Background In order to apply the right treatment for hemostatic disorders in pediatric patients, laboratory data should be interpreted with age-appropriate reference ranges. Objectives The purpose of this study was to determining age-dependent reference range values for prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen tests, and D-dimer tests. Materials and Methods A total of 320 volunteers were included in the study with the following ages: 1 month - 1 year (n = 52), 2 - 5 years (n = 50), 6 - 10 years (n = 48), 11 - 17 years (n = 38), and 18 - 65 years (n = 132). Each volunteer completed a survey to exclude hemostatic system disorder. Using a nonparametric method, the lower and upper limits, including 95% distribution and 90% confidence intervals, were calculated. Results No statistically significant differences were found between PT and aPTT values in the groups consisting of children. Thus, the reference ranges were separated into child and adult age groups. PT and aPTT values were significantly higher in the children than in the adults. Fibrinogen values in the 6 - 10 age group and the adult age group were significantly higher than in the other groups. D-dimer levels were significantly lower in those aged 2 - 17; thus, a separate reference range was established. Conclusions These results support other findings related to developmental hemostasis, confirming that adult and pediatric age groups should be evaluated using different reference ranges.

Adults with congenital heart disease (CHD) are often cared for at pediatric hospitals. There are no data describing the incidence or type of medication prescribing errors in adult patients admitted to a pediatric cardiovascular intensive care unit (CVICU). A review of patients >18 years of age admitted to the pediatric CVICU at our institution from 2009 to 2011 occurred. A comparator group <18 years of age but >70 kg (a typical adult weight) was identified. Medication prescribing errors were determined according to a commonly used adult drug reference. An independent panel consisting of a physician specializing in the care of adult CHD patients, a nurse, and a pharmacist evaluated all errors. Medication prescribing orders were classified as appropriate, underdose, overdose, or nonstandard (dosing per weight instead of standard adult dosing), and severity of error was classified. Eighty-five adult (74 patients) and 33 pediatric admissions (32 patients) met study criteria (mean age 27.5 ± 9.4 years, 53% male vs. 14.9 ± 1.8 years, 63% male). A cardiothoracic surgical procedure occurred in 81.4% of admissions. Adult admissions weighed less than pediatric admissions (72.8 ± 22.4 kg vs. 85.6 ± 14.9 kg, P < .01) but hospital length of stay was similar. (Adult 6 days [range 1-216 days]; pediatric 5 days [Range 2-123 days], P = .52.) A total of 112 prescribing errors were identified and they occurred less often in adults (42.4% of admissions vs. 66.7% of admissions, P = .02). Adults had a lower mean number of errors (0.7 errors per adult admission vs. 1.7 errors per pediatric admission, P < .01). Prescribing errors occurred most commonly with antimicrobials (n = 27). Underdosing was the most common category of prescribing error. Most prescribing errors were determined to have not caused harm to the patient. Prescribing errors occur frequently in adult patients admitted to a pediatric CVICU but occur more often in pediatric patients of adult weight. © 2013 Wiley Periodicals, Inc.

Many pediatric surgeons have limited experience of esophageal replacement. This study reports outcomes of esophageal replacement by gastric transposition performed by a single UK-based pediatric surgeon. Consecutive patients were identified who underwent esophageal replacement by gastric transposition over a 28 year period. Clinical and demographic data were collected. Weight-for-age Z-scores were calculated for esophageal atresia patients. Nineteen patients were identified. Indication in the majority was long-gap esophageal atresia (n = 17; 10 with tracheoesophageal fistula). At surgery, median age was 8.5 months (range 2-55); median weight was 7.4 kg (range 4.0-17.4 kg). A right-sided thoracotomy or transhiatal approach was used. Median postoperative length of stay was 17.5 days (range 7-130); median intensive care stay was three days (range 1-63). There were no deaths. Anastomotic leak rate at 30 days was 10.5% (n = 2). One patient required early stricture dilatation. Median weight-for-age Z-score increased from -2.17 at one year of age to -1.86, -1.70 and -1.93 at 5, 10 and 15 years. Esophageal replacement by gastric transposition offers a potentially life-changing treatment; however, it is associated with significant morbidity. The majority of patients eventually achieve full oral feeding and maintenance of weight gain trajectory. A right-sided approach to the esophagus is feasible. Treatment Study. IV.

Armed conflicts can result in humanitarian crises and have major impacts on civilians, of whom children represent a significant proportion. Usual pediatric medical care is often disrupted and trauma resulting from war-related injuries is often devastating. High pediatric mortality rates are thus experienced in these ravaged medical environments. Using simple communication technology to provide real-time management recommendations from highly trained pediatric personnel can provide substantive clinical support and have a significant impact on pediatric morbidity and mortality. We implemented a "Tele-Pediatric Intensive Care" program (Tele-PICU) to provide real-time management consultation for critically ill and injured pediatric patients in Syria with intensive care needs. Over the course of 7 months, 19 cases were evaluated, ranging in age from 1 day to 11 years. Consultation questions addressed a wide range of critical care needs. Five patients are known to have survived, three were transferred, five died, and six outcomes were unknown. Based on this limited undertaking with its positive impact on survival, further development of Tele-PICU-based efforts with attention to implementation and barriers identified through this program is desirable. Even limited Tele-PICU can provide timely and potentially lifesaving assistance to pediatric care providers. Future efforts are encouraged.

Objectives: Abdominal intensity-modulated radiation therapy and proton therapy require quantification of target and organ motion to optimize localization and treatment. Although addressed in adults, there is no available literature on this issue in pediatric patients. We assessed physiologic renal motion in pediatric patients. Methods and Materials: Twenty free-breathing pediatric patients at a median age of 8 years (range, 2-18 years) with intra-abdominal tumors underwent computed tomography simulation and four-dimensional computed tomography acquisition (slice thickness, 3 mm). Kidneys and diaphragms were contoured during eight phases of respiration to estimate center-of-mass motion. We quantified center of kidney mass mobility vectors in threemore » dimensions: anteroposterior (AP), mediolateral (ML), and superoinferior (SI). Results: Kidney motion decreases linearly with decreasing age and height. The 95% confidence interval for the averaged minima and maxima of renal motion in children younger than 9 years was 5-9 mm in the ML direction, 4-11 mm in the AP direction, and 12-25 mm in the SI dimension for both kidneys. In children older than 9 years, the same confidence interval reveals a widening range of motion that was 5-16 mm in the ML direction, 6-17 mm in the AP direction, and 21-52 mm in the SI direction. Although not statistically significant, renal motion correlated with diaphragm motion in older patients. The correlation between diaphragm motion and body mass index was borderline (r = 0.52, p = 0.0816) in younger patients. Conclusions: Renal motion is age and height dependent. Measuring diaphragmatic motion alone does not reliably quantify pediatric renal motion. Renal motion in young children ranges from 5 to 25 mm in orientation-specific directions. The vectors of motion range from 5 to 52 mm in older children. These preliminary data represent novel analyses of pediatric intra-abdominal organ motion.« less

To describe the clinical characteristics and outcome of patients admitted to pediatric intensive care with influenza A (pH1N1) 2009 in Argentina. Retrospective observational study. Thirteen pediatric intensive care units in Argentina. One hundred and forty-two patients with confirmed or suspected influenza A (H1N1). None. We included 142 critically ill patients. The median age was 19 months (range, 2-110 months) with 39% of the patients <24 months of age. Ninety-nine patients (70%) had an underlying disease. Influenza A (pH1N1) 2009 infection was confirmed in 90 patients and the remaining 52 had a positive direct immunofluorescence assay for influenza A. The median length of stay in the pediatric intensive care unit was 12 days (range, 2-52 days). One hundred eighteen patients (83%) received invasive mechanical ventilation and 19 patients were treated with noninvasive ventilation; however, seven of the patients receiving noninvasive ventilation later needed mechanical ventilation. Sixty-eight patients died (47%) with the most frequent cause refractory hypoxemia. Multivariate logistic regression analysis showed that age <24 months (odds ratio, 2.87; 2.35-3.93), asthma (odds ratio, 1.34; 1.20-2.91), and respiratory coinfection with respiratory syncytial virus (odds ratio, 2.92; 1.20-4.10) were associated with higher mortality. As expected, mechanical ventilation and treatment with inotropes were also associated with increased mortality. The mortality of children admitted to the pediatric intensive care unit with 2009 pH1N1 influenza was high (47%) in our population. Age <24 months, asthma, respiratory coinfection, need of mechanical ventilation, and treatment with inotropes were predictors of poorer outcome.

To report optical coherence tomography angiography (OCTA) values in healthy pediatric eyes and to identify factors that may modify these values. In this prospective observational cross-sectional study, macular OCTA images were acquired from healthy pediatric patients. Main outcome measures were 1) foveal avascular zone (FAZ) area at the level of the superficial retinal capillary plexus (SCP); 2) SCP and deep retinal capillary plexus (DCP) perfusion density (based on the area of vessels); 3) SCP and DCP vessel density (based on a map with vessels of 1-pixel width); and 4) CC perfusion density. Multiple regression analysis was performed to assess the effect of age, sex, ethnicity, refraction, and foveal macular thickness (FMT) on OCTA parameters. Seventy-seven eyes from 52 subjects (23 male and 29 female) were included in analysis. Mean age was 11.1 ± 3.3 years (range = 5.0-17.0 years). Twenty-nine (55.8%) subjects were white, 14 (27.0%) Hispanic, 8 (15.4%) Asian, and 1 (1.8%) African-American. Mean refraction was -0.1 ± 2.4 diopters (D) (range = -5.75 to +9.0 D). Mean FMT was 248.6 ± 18.6 μm. Larger FAZ area was significantly associated with older age (P = 0.014). Furthermore, larger FAZ area was associated with reduced FMT (P < 0.0001). Male sex was associated only with increased SCP perfusion density (P = 0.042). Increased CC perfusion density was associated with younger age (P = 0.022). We report data for pediatric OCTA parameters in healthy subjects. Several variables influence the density of macular microvascular networks, and these factors should be considered in the OCTA study of pediatric eye disorders.

In routine practice, intensive care physicians rarely have to manage children under 18years of age, particularly those under 15. This study's objectives were to assess the quality of training in pediatrics of adult intensive care teams, to document the workload generated by care of pediatric patients, and to identify the difficulties encountered in managing minors as patients. A survey was administered in Lower Normandy from 4 April 2012 to 1 September 2012. Physicians, residents, nurses, and nurses' aides practicing in one of the nine intensive care units of Lower Normandy were asked to complete an electronic or paper format questionnaire. This questionnaire assessed their level of pediatric training, the workload management of pediatric patients entailed, and the challenges posed by these patients. One hundred and nine questionnaires were returned (by 26 attending physicians, 18 residents, 38 nurses, and 27 nurses' aides). Eighty-three of the respondents (76%) had no experience in a pediatric unit of any kind. Forty-two percent thought that the pediatric age range lies between 3months and 15years of age. However, more than 50% of respondents would like the upper limit to be 16years or even older. Ninety-three respondents (85%) estimated having some exposure to pediatric patients in their routine practice, but this activity remained quite low. Seventy-three (67%) reported difficulties with the management of these young patients. This survey provides current information regarding the level of training of adult intensive care unit professionals and their concerns about managing patients under 18years of age, both in terms of workload and specific challenges.

2006-01-01

Urinary tract infections (UTIs) represent a common infection in the pediatric population. Escherichia coli is the most common uropathogen in children, and antimicrobial resistance in this species complicates the treatment of pediatric UTIs. Despite the impact of resistance on empiric antibiotic choice, there is little data on multidrug resistance in pediatric patients. In this paper, we describe characteristics of multidrug-resistant E. coli in pediatric patients using a large national database of uropathogens antimicrobial sensitivities. Antimicrobial susceptibility patterns to commonly prescribed antibiotics were performed on uropathogens isolated from children presenting to participating hospitals between 1999 and 2001. Data were analyzed separately for four pediatric age groups. Single and multidrug resistance to ampicillin, amoxicillin-clavulanate, cefazolin, ciprofloxacin, nitrofurantoin, and trimethoprim-sulfamethoxazole (TMP-SMX) were performed on all specimens. There were a total of 11,341 E. coli urine cultures from 343 infants (0-4 weeks), 1,801 toddlers (5 weeks-24 months), 6,742 preteens (2-12 years), and 2,455 teens (13-17 years). E. coli resistance to ampicillin peaked in toddlers (52.8%) but was high in preteens (52.1%), infants (50.4%), and teens (40.6%). Resistance to two or more antibiotics varied across age groups, with toddlers (27%) leading preteens (23.1%), infants (21%), and teens (15.9%). Resistance to three or more antibiotics was low in all age groups (range 3.1-5.2%). The most common co-resistance in all age groups was ampicillin/TMP-SMZ. In conclusion, less than half of all pediatric UTIs are susceptible to all commonly used antibiotics. In some age groups, there is a significant percentage of co-resistance between the two most commonly used antibiotics (ampicillin and TMP-SMZ).

To identify the prevalence of depression in Mexican pediatric patients with systemic lupus erythematosus. Analytical transversal study including patients aged 7-16 years with a diagnosis of systemic lupus erythematosus seen at the Pediatric Rheumatology Consultation Service. The disease was classified by means of the MEX-SLEDAI questionnaire. Descriptive statistics with central tendency and dispersion and comparative measurements with chi-squared and Mann-Whitney U tests. Logistic regression and association with odds ratios. SPSS v.21.0 statistical software package. We evaluated 45 patients who presented depression, n=9 (20%), including eight females (89%) and one male (11%), median age 13 years (range, 7-16) in children with depression vs. 13 years (range, 9-14) p=0.941, depression more frequent in schoolchildren. Habitual residence, disease evolution time, and duration of the immunosuppressor did not show a significant difference between both groups. Divorced parents p=0.037. Neuropsychiatric manifestations of lupus presented in 2.2% of all patients and in 100% of patients with depression. Disease activity index (MEX-SLEDAI) did not demonstrate a relationship with the presence of depression. Prevalences in pediatric populations are less that that reported in adults, association with disease activity, evolution time, and immunosuppressor use and duration not found.

Constipation is a common pediatric condition with a prevalence of 3% to 5% in children aged 4 to 17 years. Currently, there are no evidence-based guidelines for the management of pediatric patients hospitalized with constipation. The primary objective was to evaluate practice patterns and patient outcomes for the hospital management of functional constipation in US children's hospitals. We conducted a multicenter, retrospective cohort study of children aged 0 to 18 years hospitalized for functional constipation from 2012 to 2014 by using the Pediatric Health Information System. Patients were included by using constipation and other related diagnoses as classified by International Classification of Diseases, Ninth Revision . Patients with complex chronic conditions were excluded. Outcome measures included percentage of hospitalizations due to functional constipation, therapies used, length of stay, and 90-day readmission rates. Statistical analysis included means with 95% confidence intervals for individual hospital outcomes. A total of 14 243 hospitalizations were included, representing 12 804 unique patients. The overall percentage of hospitalizations due to functional constipation was 0.65% (range: 0.19%-1.41%, P < .0001). The percentage of patients receiving the following treatment during their hospitalization included: electrolyte laxatives: 40% to 96%; sodium phosphate enema: 0% to 64%; mineral oil enema: 0% to 61%; glycerin suppository: 0% to 37%; bisacodyl 0% to 47%; senna: 0% to 23%; and docusate 0% to 11%. Mean length of stay was 1.97 days (range: 1.31-2.73 days, P < .0001). Mean 90-day readmission rate was 3.78% (range: 0.95%-7.53%, P < .0001). There is significant variation in practice patterns and clinical outcomes for pediatric patients hospitalized with functional constipation across US children's hospitals. Collaborative initiatives to adopt evidence-based best practices guidelines could help standardize the hospital management of pediatric functional constipation.

Recent studies have shown the feasibility of estimating patient dose from a CT exam using CTDI(vol)-normalized-organ dose (denoted as h), DLP-normalized-effective dose (denoted as k), and DLP-normalized-risk index (denoted as q). However, previous studies were limited to a small number of phantom models. The purpose of this work was to provide dose coefficients (h, k, and q) across a large number of computational models covering a broad range of patient anatomy, age, size percentile, and gender. The study consisted of 100 patient computer models (age range, 0 to 78 y.o.; weight range, 2-180 kg) including 42 pediatric models (age range, 0 to 16 y.o.; weight range, 2-80 kg) and 58 adult models (age range, 18 to 78 y.o.; weight range, 57-180 kg). Multi-detector array CT scanners from two commercial manufacturers (LightSpeed VCT, GE Healthcare; SOMATOM Definition Flash, Siemens Healthcare) were included. A previously-validated Monte Carlo program was used to simulate organ dose for each patient model and each scanner, from which h, k, and q were derived. The relationships between h, k, and q and patient characteristics (size, age, and gender) were ascertained. The differences in conversion coefficients across the scanners were further characterized. CTDI(vol)-normalized-organ dose (h) showed an exponential decrease with increasing patient size. For organs within the image coverage, the average differences of h across scanners were less than 15%. That value increased to 29% for organs on the periphery or outside the image coverage, and to 8% for distributed organs, respectively. The DLP-normalized-effective dose (k) decreased exponentially with increasing patient size. For a given gender, the DLP-normalized-risk index (q) showed an exponential decrease with both increasing patient size and patient age. The average differences in k and q across scanners were 8% and 10%, respectively. This study demonstrated that the knowledge of patient information and CTDIvol/DLP values may be used to estimate organ dose, effective dose, and risk index in abdominopelvic CT based on the coefficients derived from a large population of pediatric and adult patients.

To determine the role of laparoscopic surgery in the treatment of pediatric urachal disorders. Case reports and a literature review of laparoscopic excision of urachal remnants. In a five-year period, three children were diagnosed with urachal anomalies presenting as abdominal or urinary symptoms, and were treated by laparoscopic surgery. The average age was 8.3 years (range, 4-13),and there were two girls and one boy. Mean operative time was 90 minutes (range, 60-120), and there were nopostoperative complications. The three patients were all discharged by postoperative day four. Laparoscopy is an effective and safe minimally invasive technique in the management of pediatricurachal anomalies. It is effective even in cases of infected urachal cysts.

Defining laboratory biomarker reference values in a healthy population and understanding the fluctuations in biomarker concentrations throughout life and between sexes are critical to clinical interpretation of laboratory test results in different disease states. The Canadian Health Measures Survey (CHMS) has collected blood samples and health information from the Canadian household population. In collaboration with the Canadian Laboratory Initiative on Pediatric Reference Intervals (CALIPER), the data have been analyzed to determine reference value distributions and reference intervals for several endocrine and special chemistry biomarkers in pediatric, adult, and geriatric age groups. CHMS collected data and blood samples from thousands of community participants aged 3 to 79 years. We used serum samples to measure 13 immunoassay-based special chemistry and endocrine markers. We assessed reference value distributions and, after excluding outliers, calculated age- and sex-specific reference intervals, along with corresponding 90% CIs, according to CLSI C28-A3 guidelines. We observed fluctuations in biomarker reference values across the pediatric, adult, and geriatric age range, with stratification required on the basis of age for all analytes. Additional sex partitions were required for apolipoprotein AI, homocysteine, ferritin, and high sensitivity C-reactive protein. The unique collaboration between CALIPER and CHMS has enabled, for the first time, a detailed examination of the changes in various immunochemical markers that occur in healthy individuals of different ages. The robust age- and sex-specific reference intervals established in this study provide insight into the complex biological changes that take place throughout development and aging and will contribute to improved clinical test interpretation. © 2015 American Association for Clinical Chemistry.

Purpose: Phantom development in medical physics plays an important role in radiation dose assessment and image quality evaluation, and this is especially true in the pediatric patient population. The purpose of this investigation was to establish the relationship between patient age and patient size, focusing on the abdomen-pelvis and head effective diameters, for patients ranging in age from newborn to 18 years. Methods: A dose reporting tool for computed tomography systems was installed at our institution to achieve compliance with state law commencing on July 1, 2012. The software records a number of patient-specific data, and also reports CT dosemore » metrics (CTDIvol and DLP) into the patients interpretive report. The database generated by the software was mined to determine patient effective diameter as a function of age for pediatric patients aged 0–18 years. CT protocols including abdomen-pelvis and routine head were evaluated, and specific to this study the patients age, gender and equivalent diameter were recorded. Results: Six age ranges were evaluated: A(0–3), B(4–6), C(7–9), D(10–12),E(13–15),F(16–18). For the torso in these groups based upon 694 patients, median effective diameters were 147, 167, 184, 214, 231, 246 mm, respectively. For the head (N=1833), median diameters were 143, 157, 162, 168, 174, and 174, respectively. Conclusion: A solid understanding of the approximate dimensions of pediatric patients as a function of age is useful in the development of age-based imaging protocols and dose assessments. CT dose-reporting tools generate a great deal of data with respect to body dimensions automatically. In this study, median equivalent diameters for the abdomen-pelvis and head of pediatric patients were evaluated. These data may prove useful in the development of both mathematical and physical phantoms for dosimetry and image quality assessment.« less

The standardization of treatment of older adults with Philadelphia chromosome negative (Ph-) acute lymphoblastic leukemia (ALL) is challenging, especially in the age range of 55-65 years. This study aimed to compare intensive, pediatric-inspired therapy with non-intensive therapy in this population of patients. The outcomes of 67 patients prospectively included in two consecutive pediatric-inspired intensive protocols (ALL-HR03 and ALL-HR11) from the Spanish PETHEMA Group were compared with those from 44 patients included in a contemporary semi-intensive protocol (ALL-OLD07). Baseline patient and ALL characteristics were similar in both groups, except for a younger median age in the intensive group (medians: 58 vs. 62 years). Patients treated intensively had a higher complete remission rate (85% vs. 64%, p = 0.005), a lower cumulative incidence of relapse (39% [95%CI, 25% to 52%] vs. 60% [95%CI, 38% to 77%], p = .003), a similar cumulative incidence of treatment-related mortality (28% [95% CI, 18%, 40%] vs. 21% [95% CI, 10%, 34%]) and superior event-free survival at 2 years (37% [95%CI, 25%-49%) vs. 21% [8%-34%], p = 0.002). On multivariable analysis the type of protocol was the only variable with independent significance for event-free survival (HR [95% CI]: 2 [1.3, 3], p = .002). Compared with less intensive chemotherapy, pediatric-inspired intensive chemotherapy significantly improves the outcome of older adults with Ph-negative ALL in the age range of 55-65 years.

To evaluate differences in child health care service delivery in Europe based on comparisons across health care systems active in European nations. A survey involved experts in child health care of 40 national pediatric societies belonging both to European Union and non-European Union member countries. The study investigated which type of health care provider cared for children in 3 different age groups and the pediatric training and education of this workforce. In 24 of 36 countries 70%-100% of children (0-5 years) were cared for by primary care pediatricians. In 12 of 36 of countries, general practitioners (GPs) provided health care to more than 60% of young children. The median percentage of children receiving primary health care by pediatricians was 80% in age group 0-5 years, 50% in age group 6-11, and 25% in children >11 years of age. Postgraduate training in pediatrics ranged from 2 to 6 years. A special primary pediatric care track during general training was offered in 52% of the countries. One-quarter (9/40) of the countries reported a steady state of the numbers of pediatricians, and in one-quarter (11/40) the number of pediatricians was increasing; one-half (20/40) of the countries reported a decreasing number of pediatricians, mostly in those where public health was changing from pediatric to GP systems for primary care. An assessment on the variations in workforce and pediatric training systems is needed in all European nations, using the best possible evidence to determine the ideal skill mix between pediatricians and GPs.

Objectives Severity of illness measures have long been used in pediatric critical care. The Pediatric Risk of Mortality is a physiologically based score used to quantify physiologic status, and when combined with other independent variables, it can compute expected mortality risk and expected morbidity risk. Although the physiologic ranges for the Pediatric Risk of Mortality variables have not changed, recent Pediatric Risk of Mortality data collection improvements have been made to adapt to new practice patterns, minimize bias, and reduce potential sources of error. These include changing the outcome to hospital survival/death for the first PICU admission only, shortening the data collection period and altering the Pediatric Risk of Mortality data collection period for patients admitted for “optimizing” care before cardiac surgery or interventional catheterization. This analysis incorporates those changes, assesses the potential for Pediatric Risk of Mortality physiologic variable subcategories to improve score performance, and recalibrates the Pediatric Risk of Mortality score, placing the algorithms (Pediatric Risk of Mortality IV) in the public domain. Design Prospective cohort study from December 4, 2011, to April 7, 2013. Measurements and Main Results Among 10,078 admissions, the unadjusted mortality rate was 2.7% (site range, 1.3–5.0%). Data were divided into derivation (75%) and validation (25%) sets. The new Pediatric Risk of Mortality prediction algorithm (Pediatric Risk of Mortality IV) includes the same Pediatric Risk of Mortality physiologic variable ranges with the subcategories of neurologic and nonneurologic Pediatric Risk of Mortality scores, age, admission source, cardiopulmonary arrest within 24 hours before admission, cancer, and low-risk systems of primary dysfunction. The area under the receiver operating characteristic curve for the development and validation sets was 0.88 ± 0.013 and 0.90 ± 0.018, respectively. The Hosmer-Lemeshow goodness of fit statistics indicated adequate model fit for both the development (p = 0.39) and validation (p = 0.50) sets. Conclusions The new Pediatric Risk of Mortality data collection methods include significant improvements that minimize the potential for bias and errors, and the new Pediatric Risk of Mortality IV algorithm for survival and death has excellent prediction performance.

Efforts to promote the development of pediatric pharmacotherapy include regulatory frameworks and close collaboration between the US Food and Drug Administration and the European Medicines Agency. We characterized the current status of pediatric clinical trials conducted in the United States by the pharmaceutical industry, focusing on the involvement of the European Union member countries, to clarify the industry perspective. Data on US pediatric clinical trials were obtained from ClinicalTrials.gov . Binary regression analysis was performed to identify what factors influence the likelihood of involvement of European Union countries. A total of 633 US pediatric clinical trials that met inclusion criteria were extracted and surveyed. Of these, 206 (32.5%) involved a European Union country site(s). The results of binary regression analysis indicated that attribution of industry, phase, disease area, and age of pediatric participants influenced the likelihood of the involvement of European Union countries in US pediatric clinical trials. Relatively complicated or large pediatric clinical trials, such as phase II and III trials and those that included a broad age range of participants, had a significantly greater likelihood of the involvement of European Union countries ( P < .05). Our results suggest that (1) the pharmaceutical industry utilizes regulatory frameworks in making business decisions regarding pediatric clinical trials, (2) disease area affects the involvement of European Union countries, and (3) feasibility of clinical trials is mainly concerned by pharmaceutical industry for pediatric drug development. Additional incentives for high marketability may further motivate pharmaceutical industry to develop pediatric drugs.

Youth with epilepsy have impaired health-related quality of life (HRQOL). Existing epilepsy-specific HRQOL measures are limited by not having parallel self- and parent-proxy versions, having a restricted age range, not being inclusive of children with developmental disabilities, or being too lengthy for use in a clinical setting. Generic HRQOL measures do not adequately capture the idiosyncrasies of epilepsy. The purpose of the present study was to develop items and content validity for the PedsQL™ Epilepsy Module. An iterative qualitative process of conducting focus group interviews with families of children with epilepsy, obtaining expert input, and conducting cognitive interviews and debriefing was utilized to develop empirically derived content for the instrument. Eleven health providers with expertise in pediatric epilepsy from across the country provided feedback on the conceptual model and content, including epileptologists, nurse practitioners, social workers, and psychologists. Ten pediatric patients (age 4-16years) with a diagnosis of epilepsy and 11 parents participated in focus groups. Thirteen pediatric patients (age 5-17years) and 17 parents participated in cognitive interviews. Focus groups, expert input, and cognitive debriefing resulted in 6 final domains including restrictions, seizure management, cognitive/executive functioning, social, sleep/fatigue, and mood/behavior. Patient self-report versions ranged from 30 to 33 items and parent proxy-report versions ranged from 26 to 33 items, with the toddler and young child versions having fewer items. Standardized qualitative methodology was employed to develop the items and content for the novel PedsQL™ Epilepsy Module. The PedsQL™ Epilepsy Module has the potential to enhance clinical decision-making in pediatric epilepsy by capturing and monitoring important patient-identified contributors to HRQOL.

Searching the optimal PTH target range in children undergoing peritoneal dialysis: new insights from international cohort studies.

PubMed

Haffner, Dieter; Schaefer, Franz

2013-04-01

The treatment of the mineral and bone disorder associated with chronic kidney disease (CKD-MBD) remains a major challenge in pediatric patients. The principal aims of therapeutic measures are not only to prevent the debilitating skeletal complications and to achieve normal growth but also to preserve long-term cardiovascular health. Serum parathyroid hormone (PTH) levels are used as a surrogate parameter of bone turnover. Whereas it is generally accepted that serum calcium and phosphate levels should be kept within the range for age, current pediatric consensus guidelines differ markedly with respect to the optimal PTH target range and operate on a limited evidence base. Recently, the International Pediatric Dialysis Network (IPPN) established a global registry collecting detailed clinical and biochemical information, including data relevant to CKD-MBD in children on chronic peritoneal dialysis (PD). This review highlights the current evidence basis regarding the optimal PTH target range in pediatric CKD patients, and re-assesses the current guidelines in view of the outcome data collected by the IPPN registry. Based on a comprehensive evaluation of CKD-MBD outcome measures in this global patient cohort, a PTH target range of 1.7-3 times the upper limit of normal (i.e. 100-200 pg/ml) appears reasonable in children undergoing chronic PD.

Penicillin allergy is commonly reported in the pediatric emergency department (ED). True penicillin allergy is rare, yet the diagnosis results from the denial of first-line antibiotics. We hypothesize that all children presenting to the pediatric ED with symptoms deemed to be low-risk for immunoglobulin E-mediated hypersensitivity will return negative results for true penicillin allergy. Parents of children aged 4 to 18 years old presenting to the pediatric ED with a history of parent-reported penicillin allergy completed an allergy questionnaire. A prespecified 100 children categorized as low-risk on the basis of reported symptoms completed penicillin allergy testing by using a standard 3-tier testing process. The percent of children with negative allergy testing results was calculated with a 95% confidence interval. Five hundred ninety-seven parents completed the questionnaire describing their child's reported allergy symptoms. Three hundred two (51%) children had low-risk symptoms and were eligible for testing. Of those, 100 children were tested for penicillin allergy. The median (interquartile range) age at testing was 9 years (5-12). The median (interquartile range) age at allergy diagnosis was 1 year (9 months-3 years). Rash (97 [97%]) and itching (63 [63%]) were the most commonly reported allergy symptoms. Overall, 100 children (100%; 95% confidence interval 96.4%-100%) were found to have negative results for penicillin allergy and had their labeled penicillin allergy removed from their medical record. All children categorized as low-risk by our penicillin allergy questionnaire were found to have negative results for true penicillin allergy. The utilization of this questionnaire in the pediatric ED may facilitate increased use of first-line penicillin antibiotics. Copyright © 2017 by the American Academy of Pediatrics.

To 1) describe the characteristics and outcomes over time of PICU patients with severe sepsis within the dedicated U.S. children's hospitals, 2) identify patient subgroups at risk for mortality from pediatric severe sepsis, and 3) describe overall pediatric severe sepsis resource utilization. Retrospective review of a prospectively collected multi-institutional children's hospital database. PICUs in 43 U.S. children's hospitals. PICU patients from birth to younger than 19 years were identified with severe sepsis by modified Angus criteria and International Classification of Diseases, 9th Revision, codes for severe sepsis and septic shock. None. Data from the Pediatric Health Information System database collected by the Children's Hospital Association from 2004 to 2012. Pediatric severe sepsis was defined by 1) International Classification of Diseases, 9th Revision, codes reflecting severe sepsis and septic shock and 2) International Classification of Diseases, 9th Revision, codes of infection and organ dysfunction as defined by modified Angus criteria. From 2004 to 2012, 636,842 patients were identified from 43 hospitals. Pediatric severe sepsis prevalence was 7.7% (49,153) with an associated mortality rate of 14.4%. Age less than 1 year (vs age 10 to < 19) (odds ratio, 1.4), underlying cardiovascular condition (odds ratio, 1.4) and multiple organ dysfunction, conferred higher odds of mortality. Resource burden was significant with median hospital length of stay of 17 days (interquartile range, 8-36 d) and PICU length of stay of 7 days (interquartile range, 2-17 d), with median cost/day of $4,516 and median total hospitalization cost of $77,446. There was a significant increase in the severe sepsis prevalence rate from 6.2% to 7.7% from 2004 to 2012 (p < 0.001) and a significant decrease in mortality from 18.9% to 12.0% (p < 0.001). Center mortality was negatively correlated with prevalence (rs = -0.48) and volume (rs = -0.39) and positively correlated with cost (rs = 0.36). In this largest reported pediatric severe sepsis cohort to date, prevalence increased from 2004 to 2012 while associated mortality decreased. Age, cardiovascular comorbidity, and organ dysfunction were significant prognostic factors. Pediatric severe sepsis remains an important cause for PICU admission and mortality and leads to a substantial burden in healthcare costs. Individual center's prevalence and volume are associated with improved outcomes.

There is no comprehensive database of pediatric anesthesiologists, their demographic characteristics, or geographic location in the United States. We endeavored to create a comprehensive database of pediatric anesthesiologists by merging individuals identified as US pediatric anesthesiologists by the American Board of Anesthesiology, National Provider Identifier registry, Healthgrades.com database, and the Society for Pediatric Anesthesia membership list as of November 5, 2015. Professorial rank was accessed via the Association of American Medical Colleges and other online sources. Descriptive statistics characterized pediatric anesthesiologists' demographics. Pediatric anesthesiologists' locations at the city and state level were geocoded and mapped with the use of ArcGIS Desktop 10.1 mapping software (Redlands, CA). We identified 4048 pediatric anesthesiologists in the United States, which is approximately 8.8% of the physician anesthesiology workforce (n = 46,000). The median age of pediatric anesthesiologists was 49 years (interquartile range, 40-57 years), and the majority (56.4%) were men. Approximately two-thirds of identified pediatric anesthesiologists were subspecialty board certified in pediatric anesthesiology, and 33% of pediatric anesthesiologists had an identified academic affiliation. There is substantial heterogeneity in the geographic distribution of pediatric anesthesiologists by state and US Census Division with urban clustering. This description of pediatric anesthesiologists' demographic characteristics and geographic distribution fills an important gap in our understanding of pediatric anesthesia systems of care.

The aim of this study was to evaluate the pharmacokinetic variations of mycophenolic acid (MPA), the active metabolite of mycophenolate mofetil (MMF), in both pediatric and adult patients following hematopoietic stem cell transplantation (HSCT). Twenty pediatric patients with a median age of 3 years (range 0.2-12 years) and 13 adult patients with a median age of 54 years (range 18-63 years) were enrolled. Blood samples were collected on days 0, 7, 14, 21, and 30 after allogeneic HSCT. Total and free (unbound) MPA as well as MPA 7-O-glucuronide (MPAG) were quantified using a validated LC-MS/MS assay. The plasma protein binding of MPA and MPAG did not change significantly in pediatric patients over the 1-month sampling period post-HSCT. However, it increased in adult patients from day 7 to day 30 post-HSCT, from 97.3 ± 0.8% to 98.3 ± 0.6% for MPA (P < .05), and 74.6 ± 9.4% to 82.9 ± 8.1% for MPAG (P < .05). The plasma protein binding of MPA was significantly higher in males compared to females in both pediatric (98.3 ± 1.1% vs 97.4 ± 1.1%) and adult (98.1 ± 0.7% vs 97.4 ± 1.2%) patients (P < .05). The MPAG/MPA ratios on a milligram-per-kilogram dose basis in adult patients were significantly higher than those in pediatric patients (4.3 ± 3.4 vs 2.4 ± 2.6; P < .05). Time-dependent plasma protein binding and age-related differences in MPA metabolism at least in part impact the reported large intra- and interindividual variability in MPA pharmacokinetics. These patient and pharmacologic factors, if incorporated into MMF regimen design and modification, may contribute to the rational dose selection of MMF in HSCT patients. © 2016, The American College of Clinical Pharmacology.

Clinical case series. To investigate the efficacy of intraoperative neuromonitoring in pediatric cervical spine surgery. Intraoperative neuromonitoring (IONM) consisting of somatosensory-evoked potentials (SSEP) and transcranial motor-evoked potentials (tcMEP) has been shown to effectively prevent permaneny neurologic injury in deformity surgery. The role of IONM during pediatric cervical spine surgery is not well documented. Advances in cervical spine instrumentation have expanded the surgical options in pediatric populations. The goal of this study is to report the ability of IONM to detect neurologic injury during pediatric cervical spine instrumentation. A single institution database was queried for pediatric-aged patients who underwent cervical spine instrumentation and fusion between 2011 and 2014. Age, diagnosis, surgical indication, number of instrumented levels, and a complete IONM were extracted. Sensitivity and specificity for the detection of neurologic deficits were calculated with exact 95% confidence intervals. Positive and negative predictive values were calculated with estimated 95% confidence intervals. Sixty-seven patients who underwent cervical spine instrumentation were identified with a mean age of 11.6 years (range 1-18). Diagnoses included instability (27), congenital (11), kyphosis (8), fracture (7), tumor (7), arthritis (4), and basilar invagination (3). Mean number of vertebral levels fused was 4 (range 2-7). All patients underwent cervical instrumentation with SSEP and tcMEP monitoring. A significant change in tcMEP monitoring was observed in 7 subjects (10%). There were no corresponding SSEP changes in these patients. The sensitivity of combined IONM was 75% [95% CI = 24.9, 98.7] and the specificity was 98.5% [92.7, 99.9]. tcMEP is a more sensitive indicator to spinal cord injury than SSEP, which is consistent with previous studies. IONM changes in 10% of a patient population are significant enough to warrant intraoperative determination if true SCI has occurred or is underway and intervene accordingly. 4.

Although blood pressure (BP) monitoring is a recommended standard of care by the ASA, and pediatric anesthesiologists routinely monitor the BP of their patients and when appropriate treat deviations from 'normal', there is no robust definition of hypotension in any of the pediatric anesthesia texts or journals. Consequently, what constitutes hypotension in pediatric anesthesia is currently unknown. We designed a questionnaire-based survey of pediatric anesthesiologists to determine the BP ranges and thresholds used to define intraoperative hypotension (IOH). Members of the Society of Pediatric Anesthesia (SPA) and the Association of Paediatric Anaesthetists (APA) of Great Britain and Ireland were contacted through e-mail to participate in this survey. We asked a few demographic questions and five questions about specific definitions of hypotension for different age groups of patients undergoing inguinal herniorraphy, a common pediatric surgical procedure. The overall response rate was 56% (483/860), of which 76% were SPA members. Majority of the respondents (72%) work in academic institutions, while 8.9% work in institutions with fewer than 1000 annual pediatric surgical caseload. About 76% of respondents indicated that a 20-30% reduction in baseline systolic blood pressure (SBP) indicates significant hypotension in children under anesthesia. Most responders (86.7%) indicated that they use mean arterial pressure or SBP (72%) to define IOH. The mean SBP values for hypotension quoted by SPA members was about 5-7% lower across all pediatric age groups compared to values quoted by APA members (P = 0.001 for all age groups). There is great variability in the BP parameters used and the threshold used for defining and treating IOH among pediatric anesthesiologists. The majority of respondents considered a 20-30% reduction from baseline in SBP as indicative of significant hypotension. Lack of a consensus definition for a common clinical condition like IOH could have implications for patient care as well as future clinical research.

To investigate school absenteeism among childhood cancer survivors and their siblings and examine factors related to absenteeism in survivors. A cross-sectional study was conducted among consecutive cancer survivors attending a large pediatric cancer survivor clinic. Absenteeism rates were obtained for survivors and their closest in age sibling from school report cards. Absenteeism was compared with a population control group of 167752 students using 1-sample t tests. The Child Vulnerability Scale, Pediatric Quality of Life Inventory, and Behavior Assessment System for Children were administered to survivors. Univariate and multiple regression analyses assessed variables associated with days absent. One hundred thirty-one survivors (median age at assessment: 13.4 years, range 8.0-19.2; median age at diagnosis: 9.4 years, range 4.3-17.3) and 77 siblings (median age at assessment: 13 years, age range 7-18) participated. Survivors and siblings missed significantly more school days than the population control group (mean ± SD: 9.6 ± 9.2 and 9.9 ± 9.8 vs 5.0 ± 5.6 days, respectively, P < .0001). Among matched survivor-sibling pairs (N = 77), there was no difference in absenteeism (9.6 ± 9.2 vs 9.9 ± 9.8 days, P = .85). Absenteeism in survivors was significantly associated with a low Pediatric Quality of Life Inventory Physical Health Summary Score (P = .01). Parents' perception of their child's vulnerability and emotional and social functioning were not associated with absenteeism. Childhood cancer survivors and siblings miss more school than the general population. The only predictor of absenteeism in survivors is poor physical quality of health. More research should be devoted to school attendance and other outcomes in siblings of childhood cancer survivors. Copyright © 2013 Mosby, Inc. All rights reserved.

Background Pediatric-onset multiple sclerosis (MS) patients represent a subpopulation who are diagnosed during the course of development. Social cognitive deficits have recently been recognized in adults with MS. It is critical to identify if these youngest patients with the disorder are also at risk. Objective To determine whether pediatric-onset MS is associated with social cognitive deficits. Methods Consecutively-recruited participants with pediatric-onset MS were compared to a group of age- and gender-matched healthy controls on Theory of Mind (ToM) task performance. Tasks measured facial affect recognition (Reading the Mind in the Eyes Test), understanding social faux pas (Faux Pas Test), and understanding the perspective of another (False Beliefs Task). Results Twenty-eight (28) pediatric-onset MS participants (median age 17 years) and 32 healthy controls (median age 16 years) completed the study. The MS participants performed worse than controls on all three ToM tasks: Reading the Mind in the Eyes Test (p=0.008), the Faux-Pas Test (p=0.009), and the False Beliefs Task (p=0.06). While more MS than control participants were impaired on a measure of information processing speed (the Symbol Digit Modalities Test; 38% versus 6%), it did not account for the differences in ToM performance. Conclusions Social cognition may represent an area of cognitive functioning affected by MS in the pediatric-onset population. These processes are especially important to study in younger patients as these deficits could have long range implications on social adjustment, employment, and well-being. PMID:24647558

Age-related changes in the anatomy and physiology of infants and children produce normal ranges for electrocardiogram features that differ from adults and vary with age. Bradycardia is defined as a heart rate below the lowest normal value for age. Pediatric bradycardia most commonly manifests as sinus bradycardia, junctional bradycardia, or atrioventricular block. As a result of several different etiologies, it may occur in an entirely structurally normal heart or in association with concomitant congenital heart disease. Genetic variants in multiple genes have been described to date in the pathogenesis of inherited sinus node dysfunction or progressive cardiac conduction disorders. Management and eventual prognosis of bradycardia in the young are entirely dependent upon the underlying cause. Reasons to intervene for bradycardia are the association of related symptoms and/or the downstream risk of heart failure or pause-dependent tachyarrhythmia. The simplest aspect of severe bradycardia management is reflected in the Pediatric and Advanced Life Support (PALS) guidelines. Early diagnosis and appropriate management are critical in many cases in order to prevent sudden death, and this review critically assesses our current practice for evaluation and management of bradycardia in neonates and children.

Background Vancomycin treatment failure has been associated with low serum vancomycin trough concentrations, prompting recommendations to increase the daily doses in adults and children. Despite more aggressive vancomycin dosing, there continues to be significant variability in vancomycin trough concentrations in pediatric patients. Methods To determine if vancomycin trough concentrations in pediatric patients differ by age and weight, we reviewed records of hospitalized patients who received vancomycin between 2008 and 2012. Patients were divided into groups that received vancomycin 40 mg/kg/day (2008 to 2009) or 60 mg/kg/day (2010 to 2012). Vancomycin trough concentrations were compared between groups and within the 60-mg/kg/day group, stratified by patient age and weight. Results After increasing the vancomycin dose from 40 mg/kg/day to 60 mg/kg/day, initial trough concentrations increased significantly in patients younger than 2 and greater than 6 years of age, but not in patients between the ages of 2 and 5 years. In the 60-mg/kg/day group, only 16.7% of patients between 2 and 5 years of age had initial trough concentrations in the therapeutic range (10 mcg/mL to 20 mcg/mL). Initial trough concentrations were therapeutic in a greater proportion of patients ages 6 years to 12 years (38.7%) and 13 years to 18 years (63.0%). Patients between the ages of 13 and 18 had the highest proportion of supratherapeutic initial vancomycin trough concentrations (14.8%). Patients weighing > 50 kg had significantly higher trough concentrations than patients ≤ 50 kg (17.1 mcg/mL vs. 9.3 mcg/mL; p<0.001). Conclusion Although increasing the vancomycin dose from 40 mg/kg/day to 60 mg/kg/day led to a significant increase in vancomycin trough concentrations, a large proportion of patients receiving 60 mg/kg/day of vancomycin had trough concentrations outside of the therapeutic range. Specifically, patients younger than 6 years tend to have low trough concentrations, while adolescents and children > 50 kg are more likely to have elevated trough concentrations. Vancomycin dosing strategies in pediatric patients should consider age and weight as well as renal function and indication. PMID:23864541

The use of resorbable plates and screws for fixation of pediatric facial fractures is both well tolerated and effective. It enables realignment and stable positioning of rapidly healing fracture segments while obviating any future issues secondary to long-term metal retention. Forty-four pediatric facial fractures were treated over a 10-year period at our institution using differing techniques of polymeric bone fixation. Twenty-nine mandible fractures in patients under the age of 10 (age range, 6 months to 8 years) were treated. Displaced fractures of the symphysis, parasymphysis, body, and ramus underwent open reduction and either 1.5-mm or 2.0-mm plate and screw fixation in 14 patients. Subcondylar fractures were treated by a short period of maxillomandibular fixation (3 weeks) achieved with suture ligation between resorbable screws placed at the zygoma and symphysis or a circummandibular suture attached to a zygomatic screw. Fifteen patients (age range, 4 to 11 years) with isolated frontal, supraorbital, intraorbital, or orbitozygomatic fractures were treated by open reduction and internal fixation with 1.5-mm resorbable plates, mesh, and screws. No long-term implant-related complications were seen in any of the treated patients. Resorbable polylactic and polyglycolic acid plates and screws can be an effective fixation method for facial fractures in children in the primary and secondary dentition periods.

To evaluate the efficacy and safety of lacosamide in pediatric patients with refractory focal epilepsy. We reviewed retrospectively the medical records of children younger than 18 years of age treated at Seoul National University Bundang Hospital, in whom oral lacosamide was used as an adjunctive treatment for refractory focal epilepsy. Clinical information regarding the patients' epilepsy and the outcome of lacosamide treatment was gathered and analyzed. Twenty-one patients (16 boys, 5 girls) were included, with a median age of 13.9 (range, 1.2-17.9) years. The mean number of concomitant antiepileptic drugs was 3.0 (range, 1-6) and the mean duration of follow-up was 10.1 (range, 6.1-13.0) months. The mean maintenance dose of lacosamide was 5.4 (range, 1.4-9.8) mg/kg/day. Fourteen patients (67%) were responders; four of these were seizure free at the last follow-up. Seven patients (33%) were nonresponders: two of these presented with <50% seizure reduction and five showed no change in seizure frequency. Two patients (10%) discontinued oral lacosamide because of adverse events (aggressive behavior and depression). Mild transient treatment-related adverse events were observed in eight of the 21 patients (38%). Lacosamide represents a useful drug that is effective for a wide range of pediatric refractory focal epilepsy and is well tolerated. Copyright © 2013 The Japanese Society of Child Neurology.

To obtain objective measurements of motor speech characteristics in normal children, using a computer-based motor speech software program. Cross-sectional, observational design in a university-based ambulatory pediatric otolaryngology clinic. Participants included 112 subjects (54 females and 58 males) aged 4-18 years. Participants with previously diagnosed hearing loss, voice and motor disorders, and children unable to repeat a passage in English were excluded. Voice samples were recorded and analysed using the Motor Speech Profile (MSP) software (KayPENTAX, Lincoln Park, NJ). The MSP produced measures of diadochokinetics, second formant transition, intonation, and syllabic rates. Demographic data, including sex, age, and cigarette smoke exposure were obtained. Normative data for several motor speech characteristics were derived for children ranging from age 4 to 18 years. A number of age-dependent changes were indentified, including an increase in average diadochokinetic rate (p<0.001) and standard syllabic duration (p<0.001) with age. There were no identified differences in motor speech characteristics between males and females across the measured age range. Variations in fundamental frequency (Fo) during speech did not change significantly with age for both males and females. To our knowledge, this is the first pediatric normative database for the MSP progam. The MSP is suitable for testing children and can be used to study developmental changes in motor speech. The analysis demonstrated that males and females behave similarly and show the same relationship with age for the motor speech characteristics studied. This normative database will provide essential comparative data for future studies exploring alterations in motor speech that may occur with hearing, voice, and motor disorders and to assess the results of targeted therapies.

Behavioral rating scales represent one potential method for screening of cognitive functioning in routine clinical care. It is not yet known if objective performance based measures and behavioral rating scales of cognitive functioning completed by parents yield similar information in pediatric endocrinology patients. The purpose of the present study was to evaluate the associations between performance-based measures and behavioral rating scales of memory and attention/concentration completed by parents of pediatric patients with Type 1 Diabetes or obesity. The sample consisted of 73 pediatric patients with Type 1 Diabetes or obesity (BMI > 95th percentile) ages 6-16 years (mean age = 12.29 years) referred to an outpatient pediatric endocrinology clinic. Youth were administered the Wide Range Assessment of Memory and Learning (WRAML-2). Parents completed the Child Behavior Checklist (CBCL) and the PedsQL Cognitive Functioning Scale. Pearson's Product Moment Correlations were examined among the performance-based measures and behavioral rating scales. All intercorrelations between the performance-based measures and behavioral rating scales completed by parents were in the small range. The only statistically significant (P < 0.05) and approaching medium correlation was between the PedsQL Cognitive Functioning Scale and WRAML-2 Verbal Memory Index (r = 0.28). On behavioral rating scales and performance-based measures of visual memory and attention/concentration, our sample exhibited greater difficulties than healthy youth from previously published data (P < 0.05). One possible explanation for our findings is that behavioral rating scales of attention/concentration and memory completed by parents measure different aspects of cognitive functioning than performance based measures in pediatric patients with Type 1 Diabetes or obesity.

Perforator-based propeller flaps for leg reconstruction in pediatric patients.

Perforator-based propeller flaps provide adequate soft tissue coverage for leg reconstruction. The aim of this study was to assess the versatility and reliability of the use of propeller flaps for leg reconstruction in pediatric patients. Seven male pediatric patients ranging in age from 2 to 13 years with a mean age of 6.7 underwent perforator-based propeller flap surgery over a four-year period. The defects resulted from burn injuries (n = 4) and traffic accidents (n = 3). The injuries were located on the ankles of four patients and on the knee, anterior lower tibia, and foot dorsum of the other three patients, respectively. The flap sizes ranged from 5 × 3 to 10 × 6 cm with a mean flap size of 7.6 × 4.3 cm. Flap harvesting time ranged from 38 to 56 m with a mean of 46 m. The rotation degree range of the flaps was from 90° to 180°. The propeller flaps were based on the posterior tibial artery (n = 4), anterior tibial artery (n = 2), and the descending branch of the lateral circumflex femoral artery (n = 1). All flaps survived completely without surgical complication; however, one patient developed disseminated intravascular coagulation syndrome two days post-surgery and died within four days. Perforator-based propeller flap reconstruction is a safe, reliable, and versatile method for lower extremities in pediatric patients; however, it requires meticulous surgical dissection and extreme patience during the surgical procedure.

Few published reports describe nutrition provision for critically ill children and young adults with acute kidney injury receiving continuous renal replacement therapy. The goals of this study were to describe feeding practices in pediatric continuous renal replacement therapy and to evaluate factors associated with over- and under-prescription of protein and calories. Retrospective database study. Multicenter study in pediatric critical care units. Patients with acute kidney injury (estimated glomerular filtration rate < 75 mL/min/1.73 m at continuous renal replacement therapy initiation) enrolled in the Prospective Pediatric Continuous Renal Replacement Therapy Registry. None. Nutrition variables: initial and maximal protein (g/kg/day) and caloric (kcal/kg/day) prescription and predicted resting energy expenditure (kcal/kg/day). We determined factors predicting initial and maximal protein and caloric prescription by multivariate analysis. One hundred ninety-five patients (median [interquartile range] age = 8.1 [12.8] yrs, 56.9% men) were studied. Mean protein and caloric prescriptions at continuous renal replacement therapy initiation were 1.3 +/- 1.5 g/kg/day (median, 1.0; range, 0-10) and 37 +/- 27 kcal/kg/day (median, 32; range, 0-107). Mean maximal protein and caloric prescriptions during continuous renal replacement therapy were 2.0 +/- 1.5 g/kg/day (median, 1.7; range, 0-12) and 48 +/- 32 kcal/kg/day (median, 43; range, 0-117). Thirty-four percent of patients were initially prescribed < 1 g/kg/day protein; 23% never attained > 1 g/kg/day protein prescription. By continuous renal replacement therapy day 5, median protein prescribed was > 2 g/kg/day. Protein prescription practices differed substantially between medical centers with 5 of 10 centers achieving maximal protein prescription of > 2 g/kg/day in > or = 40% of patients. Caloric prescription exceeded predicted resting energy expenditure by 30%-100%. Factors independently associated with maximal protein and caloric prescription while on continuous renal replacement therapy were younger age, initial protein and caloric prescription and number of continuous renal replacement therapy treatment days (p < 0.05). Protein prescription in pediatric continuous renal replacement therapy may be inadequate. Inter-center variation exists with respect to nutrition prescription. Feeding practice standardization and research in pediatric acute kidney injury nutrition are essential to begin providing evidence-based feeding recommendations.

A congenital adhesion band is a rare condition, but may induce a small bowel obstruction (SBO) at any age. However, only a few sporadic case reports exit. We aimed to identify the clinical characteristics of congenital adhesion band manifesting a SBO stratified by age group between pediatric and adult patients. The medical records of all patients with a SBO between Jan 1, 2009 and Dec 31, 2015 were retrospectively reviewed. Cases associated with previous surgical procedure and cases of secondary obstruction due to inflammatory processes or tumor and other systemic diseases were excluded. The patients were divided into two groups according to age below or above 18 years: pediatric and adult. The basic clinical characteristics were analyzed and compared between groups. Of 251 patients with a SBO, 15 (5.9%) met the inclusion criteria; 10 cases in pediatric group (mean age 17.9 ± 38.7 months) and 5 cases in adult group (mean age 60.0 ± 19.7 years). The pediatric group (66.6%) included 3 neonates, 5 infants, and 2 school children. They usually presented with bilious vomiting (50.0%) and abdominal distention (60.0%), and demonstrated a high rate of early operation (80.0%) and bowel resection (70.0%). In contrast, the adult group (33.3%) presented with abdominal pain (100%) in all cases and underwent a relatively simple procedure of band release using a laparoscopic approach (60%). However, group differences did not reach statistical significance. In addition, two groups did not differ in the time interval to the operation or in the range of the operation (p = 0.089 vs. p = 0.329). No significant correlation was found between the time interval to the operation and the necessity of bowel resection (p = 0.136). There was no mortality in either group. Congenital adhesion band is a very rare condition with diverse clinical presentations across ages. Unlike adult patients, pediatric patients showed a high proportion of early operation and bowel resection. A good result can be expected with an early diagnosis and prompt management regardless of age.

To assess physicians' knowledge and beliefs regarding vestibular evoked myogenic potential (VEMP) testing in children. A survey was delivered via email in html format to 1069 members of the American Academy of Otolaryngology--Head and Neck Surgery who identified as pediatric otolaryngologists. Study data were collected and managed using the Research Electronic Data Capture (REDCap) tools. 443 (41.4%) physicians opened the email. 190 (42.9% of opens) initiated the survey, of which 117 (61.9%) fully completed the survey of the physicians who responded to a question regarding knowledge of VEMP, 16% of respondents had never heard of the test. 16% of participants would use it in the setting of diagnosing pediatric conductive hearing loss. Responses regarding the youngest age at which VEMP is possible ranged from younger than 6 months through greater than 13 years of age. Beliefs regarding utility and reliability of VEMP varied, with 'unsure' as the most frequent response. Additionally, only 26% of pediatric otolaryngologists indicated some access to the test. The knowledge and availability of VEMP testing in the pediatric otolaryngology community varies widely. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Pediatric mandibular fractures: a free hand technique.

The treatment of pediatric mandibular fractures is rare, controversial, and complicated by mixed dentition. To determine if open mandibular fracture repair with intraoral and extraoral rigid plate placement, after free hand occlusal and bone reduction, without intermaxillary fixation (IMF), is appropriate and to discuss postoperative advantages, namely, maximal early return of function and minimal oral hygiene issues. A group of 29 pediatric patients with a mandibular fracture were examined. Twenty pediatric patients (13 males and 7 females) with a mean age of 9 years (age range, 1-17 years) were treated using IMF. All patients were treated by the same surgeon (G.S.). Surgical time for plating was reduced by 1 hour, the average time to place patients in IMF. The patients who underwent open reduction internal fixation without IMF ate a soft mechanical diet by postoperative day 3 compared with postoperative day 16 for those who underwent IMF. Complication rates related to fixation technique were comparable at 20% for those who did not undergo IMF and 33% for those who did. We believe that free hand reduction is a valuable technique to reduce operative time for pediatric mandibular fractures. It maximizes return to function while minimizing the oral hygiene issues and hardware removal of intermaxillary function.

Purpose: Investigate the correlation of SSDE with organ dose in a pediatric population. Methods: Four anthropomorphic phantoms, representing a range of pediatric body habitus, were scanned with MOSFET dosimeters placed at 23 organ locations to determine absolute organ dosimetry. Phantom organ dosimetry was divided by phantom SSDE to determine correlation between organ dose and SSDE. Correlation factors were then multiplied by patient SSDE to estimate patient organ dose. Patient demographics consisted of 352 chest and 241 abdominopelvic CT examinations, 22 ± 15 kg (range 5−55 kg) mean weight, and 6 ± 5 years (range 4 mon to 23 years) meanmore » age. Patient organ dose estimates were compared to published pediatric Monte Carlo study results. Results: Phantom effective diameters were matched with patient population effective diameters to within 4 cm. 23 organ correlation factors were determined in the chest and abdominopelvic region across nine pediatric weight subcategories. For organs fully covered by the scan volume, correlation in the chest (average 1.1; range 0.7−1.4) and abdominopelvic (average 0.9; range 0.7−1.3) was near unity. For organs that extended beyond the scan volume (i.e., skin, bone marrow, and bone surface), correlation was determined to be poor (average 0.3; range: 0.1−0.4) for both the chest and abdominopelvic regions, respectively. Pediatric organ dosimetry was compared to published values and was found to agree in the chest to better than an average of 5% (27.6/26.2) and in the abdominopelvic region to better than 2% (73.4/75.0). Conclusion: Average correlation of SSDE and organ dosimetry was found to be better than ± 10% for fully covered organs within the scan volume. This study provides a list of organ dose correlation factors for the chest and abdominopelvic regions, and describes a simple methodology to estimate individual pediatric patient organ dose based on patient SSDE.« less

Subspecialty pediatric practice provides comprehensive medical care for a range of ages, from premature infants to children, and often includes adults with complex medical and surgical issues that warrant multidisciplinary care. Normal physiologic variations involving different body systems occur during sleep and these vary with age, stage of sleep, and underlying health conditions. This article is a concise review of the cardiovascular (CV) physiology and pathophysiology in children, sleep-disordered breathing (SDB) contributing to CV morbidity, congenital and acquired CV pathology resulting in SDB, and the relationship between SDB and CV morbidity in different clinical syndromes and systemic diseases in the expanded pediatric population.

Since it was approved by the Food and Drug Administration in October 2000, Crotalidae Polyvalent Immune Fab (CroFab) has largely replaced previously used crotaline antivenom. CroFab is more specifically tailored for crotalids of North America and is less allergenic than whole immunoglobulin antivenoms. However, premarketing and postmarketing studies have excluded children. To describe the safety and efficacy of CroFab in pediatric crotaline envenomations. Using admission and billing records, the authors identified all children 13 years of age and younger treated with CroFab at a pediatric hospital between October 2000 and September 2005. Charts were reviewed by two trained, blinded extractors. Data regarding age, signs of envenomation, laboratory values, total antivenom vials used, total vials used to gain control, transfused blood products, signs of acute allergy to antivenom, and any surgical procedures were abstracted. Data were analyzed using descriptive statistics. Twenty-four patients were identified, and their mean age was 7.3 (range, 1.9-13) years. At presentation, all had swelling, 14 (58%) had a prothrombin time >13 seconds, two (8.3%) had a fibrinogen level <150 mg/dL, and three (12.5%) had platelet counts <150,000/mL. The mean number of total antivenom vials used was 12.3 (range, 4-24). Five patients had resolution of swelling, but platelet counts continued to fall despite antivenom treatment. No patient required blood products, debridement of skin, or fasciotomy. There was only one (4.2%) possible acute allergy to CroFab, and there were no deaths. In this pediatric series, CroFab appears safe and effective, despite occasional resistant thrombocytopenia.

Commercially premixed 3-chamber bags for pediatric parenteral nutrition are available for hospitalized children.

Colomb, Virginie

Hospitalized children are vulnerable to malnutrition during serious illness or recovery from injury and are at subsequent risk of increased morbidity and growth retardation. In cases in which enteral nutrition is not possible, parenteral nutrition (PN) can be used to ensure that patients at nutritional risk receive appropriate amounts of macro- and micronutrients. Nutritional needs cannot be met by 1 standard PN formulation in pediatric patients (term to 18 y) because of the wide range of needs according to age, weight, degree of maturity, and disease state. Preparation of individualized PN is associated with several limitations, including prescribing errors, stability issues, and risk of infection. These risks may be avoided by the availability of a range of pediatric PN formulations provided as commercial premixed 3-chamber bags (3-CBs). These 3-CBs were developed in conjunction with experienced neonatologists and pediatricians in accordance with international guidelines. A prospective study has previously shown the practical handling and ease of use of 2 formulations of these 3-CBs, 1 designed for term infants and toddlers up to 2 y of age and 1 for children and adolescents aged 2-18 y. The majority of pharmacists and nurses described the 3-CB as easy to use and favored it over individual bottles, bags compounded on the ward, ready-to-use compounded bags, and premixes prepared by the pharmacy and tailored to patient needs. These formulations offer a means of improving the quality of care in hospital pediatric units, particularly in the absence of a nutrition support team.

The incidence of acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) in adolescent and young adult (AYA) patients (age range, 15-39 years) in the United States is increasing at a greater rate than in younger or older persons. Their optimal treatment has been increasingly debated as pediatric regimens have become more widely used in the age group. This review compares the basic features of pediatric and adult chemotherapy regimens for ALL and LBL, recognizes and describes the challenges of the pediatric regimen, and suggests strategies to facilitate its adoption for AYAs with ALL and LBL. All but 2 of 25 published comparisons of outcomes with pediatric and adult regimens for ALL and LBL in AYAs and 1 meta-analysis favor the pediatric regimen. After more than a half-century of clinical trials of the pediatric regimens, including at least 160 phase 3 trials in the United States, the pediatric regimens have become far more complex than most adult regimens. Asparaginase, a critical component of the pediatric regimens, is more difficult to administer to AYAs (and older patients) but nonetheless has a favorable benefit to toxicity ratio for AYAs. A dramatic reduction in outcome of ALL and LBL during the AYA years (the "survival cliff") is coincident with similar reductions in proportions of AYAs referred to academic centers and enrolled on clinical trials (the "accrual cliff" and "referral cliff"). The accumulating data increasingly support treating AYAs with ALL and LBL with a pediatric-inspired regimen or an approved institutional or national clinical trial tailored for this patient group. A need to develop clinical trials specifically for AYAs and to encourage their participation is paramount, with a goal to improve both the quantity and quality of survival.

Our objective in this report was to describe the epidemiologic features of and workload associated with pediatric admissions to 12 US Army military hospitals deployed to Iraq and Afghanistan. The Patient Administration Systems and Biostatistics Activity database was queried for all local national patients <18 years of age who were admitted to deployed Army hospitals in Afghanistan and Iraq between December 2001 and December 2004. Pediatric admissions during the study period were 1012 (4.2%) of 24,227 admissions, occupying 10% of all bed-days. The median length of stay was 4 days (interquartile range: 1-8 days). The largest proportion of children were 11 to 17 years of age (332 of 757 children; 44%), although 45 (6%) of 757 children hospitalized were <1 year of age. The majority (63%) of pediatric patients admitted required either general surgical or orthopedic procedures. The in-hospital mortality rate for all pediatric patients was 59 (5.8%) of 1012 patients, compared with 274 (4.5%) of 6077 patients for all adult non-US coalition patients. Pediatric patients with injuries threatening life, limb, or eyesight are part of the primary responsibility of military medical facilities during combat and have accounted for a significant number of admissions and hospital bed-days in deployed Army hospitals in Afghanistan and Iraq. Military medical planners must continue to improve pediatric medical support, including personnel, equipment, and medications that are necessary to treat children injured during combat operations, as well as those for whom the existing host nation medical infrastructure is unable to provide care.

Context: Patients with von Hippel-Lindau (VHL) syndrome have a 25–30% chance of developing pheochromocytoma. Although practice guidelines recommend biochemical and radiological screening every 1–2 years for pheochromocytoma in patients with VHL, there are limited data on the optimal age and frequency for screening. Objective: Our objective was to determine the earliest age of onset and frequency of contralateral and recurrent pheochromocytomas in patients with VHL syndrome. Methods: This is a retrospective analysis of a prospective cohort of patients with VHL enrolled in a natural history study. Results: A total of 273 patients diagnosed with VHL were enrolled in a natural history clinical study. Thirty-one percent (84) were diagnosed with pheochromocytoma. The mean age of diagnosis was 28.8 ± 13.9 years. The earliest age at diagnosis was 5.5 years. Median follow-up for the cohort was 116.6 months (range, 0.1–613.2). Ninety-nine percent (83) of patients underwent adrenalectomy. Fifty-eight and 32% of patients had metanephrines and/or catecholamines elevated more than two times and more than four times the upper limit of normal, respectively. Twenty-five percent (21) of pheochromocytomas were diagnosed in pediatric patients younger than 19 years of age, and 86% and 57% of pediatric patients had an elevation more than two times and more than four times upper limit of normal, respectively. Eight patients had a total of nine recurrences. The median age at recurrence was 33.5 years (range, 8.8–51.9). Recurrences occurred as short as 0.5 years and as long as 39.7 years after the initial operation. Conclusions: Our findings among VHL pediatric patients supports the need for biochemical screening starting at age 5 with annual lifelong screening. PMID:26451910

Pediatric populations, including those with autistic disorder or other pervasive developmental disorders, increasingly are being prescribed selective serotonin reuptake inhibitors (SSRIs). Little is known about the age-related brain pharmacokinetics of SSRIs; there is a lack of data regarding optimal dosing of medications for children. The authors used fluorine magnetic resonance spectroscopy ((19)F MRS) to evaluate age effects on whole-brain concentrations of fluvoxamine and fluoxetine in children taking SSRIs. Twenty-one pediatric subjects with diagnoses of autistic disorder or other pervasive developmental disorders, 6-15 years old and stabilized with a consistent dose of fluvoxamine or fluoxetine, were recruited for the study; 16 successfully completed the imaging protocol. Whole-brain drug levels in this group were compared to similarly acquired data from 28 adults. A significant relationship between dose and brain drug concentration was observed for both drugs across the age range studied. Brain fluvoxamine concentration in the children was lower, consistent with a lower dose/body mass drug prescription; when brain concentration was adjusted for dose/mass, age effects were no longer significant. Brain fluoxetine concentration was similar between age groups; no significant age effects on brain fluoxetine drug levels remained after adjustment for dose/mass. Observations of brain fluoxetine bioavailability and elimination half-life also were similar between age groups. These findings suggest that fluvoxamine or fluoxetine prescriptions adjusted for dose/mass are an acceptable treatment approach for medicating children with autistic disorder or other pervasive developmental disorders. It must be determined whether these findings can be generalized to other pediatric populations.

To study the incidence, risk factors, and treatment of hemorrhagic cystitis secondary to BK-virus reactivation (HC-BKV) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the pediatric population. Case-control study in which all pediatric patients (0-18 years) who underwent allo-HSCT from September 2009 to January 2014 were followed. Twenty-nine patients underwent an allo-HSCT. The median age was 9 years (range = 6 months to 15 years), 61% male. The primary diagnosis was acute lymphoblastic leukemia (72.4%). Six (20.7%) developed HC-BKV. In a multivariate analysis of risk factors, it was observed that the reactivation of BK virus was associated with age more than 10 years (P = .098) and those with positive serology for Epstein-Barr virus (P = .06). Five of the 6 patients with HC-BKV received cidofovir (CDV) at doses of 3 to 5 mg/kg/week. The treatment lasted a median of 3 cycles (range = 2-5). One of the patients (20%) developed nephrotoxicity. Of the 5 patients treated with CDV, 3 (60%) had a complete response, 1 (20%) partial response, and 1 (20%) no response. We conclude that HC-BKV is a frequent complication after allo-HSCT. CDV therapy can be effective but controlled clinical trials are needed. © 2016 by Association of Pediatric Hematology/Oncology Nurses.

In the case of pediatric medicinal products the selection of an appropriate and palatable liquid dosage form can make the difference between treatment success and failure. Since the recent adoption of Pediatric Regulations in the U.S. and E.U., there is a greater demand for age-appropriate medicines for children. Extended research on the use of milk on drug administration in pediatric population has shown the multiple benefits of its use. Milk exhibits great solubilizing, gastroprotective and taste masking properties, which are very important characteristics in the case of insoluble, irritating and bitter-tasting active compounds. Milk-based formulations rely on a novel, simple and user-friendly approach for the delivery of ionized and unionized lipophilic drugs. In parallel they can provide critical nutritive elements and a wide range of biologically active peptides, very important elements especially for pediatric patients. Copyright © 2015.

Cervical spine injuries are uncommon in pediatric trauma patients. Previous studies were often limited by the small numbers of patients available for evaluation. The aim of this study was to determine the incidence and characteristics of pediatric cervical spine injuries at this Level 1 trauma center and to review the authors' experiences with documented cases. This study retrospectively analyzed the clinical records of all pediatric trauma patients with skeletal and/or nonskeletal injuries of the spine that were admitted to this Level 1 trauma center between 1980 and 2004. Those with significant injuries of the cervical spine were identified and included in this study. Pediatric patients were defined as patients younger than the age of 17 years. In addition, they were stratified by age into two study groups: group A included patients aged 8 years or fewer and group B contained patients from the ages of 9 to 16 years. We found 56 pediatric patients with injuries of the cervical spine that met criteria for inclusion. Thirty-one female and 25 male patients with an average age of 8.9 years (range, 1-16 years) sustained significant skeletal and/or nonskeletal injuries of the cervical spine and were entered in this study. Thirty patients (54%) were aged 8 years or fewer and entered into study group A, whereas 26 patients (46%) from the ages of 9 to 16 met criteria for inclusion in study group B. An analysis of data revealed that younger patients (group A) showed significantly more injuries of the upper cervical spine, whereas older children (group B) sustained significantly more injuries of the lower level. Spinal cord injuries without radiographic findings were only found in study group A. In addition, younger children were more likely injured by motor vehicle crashes, whereas older children more commonly sustained C-spine injuries during sports activities. Two-thirds of our patients showed neurologic deficits, and the overall mortality was 28%. The results of our study were similar to several previous reports, underscoring a low incidence (1.2%) and age-related characteristics. Younger children had a predilection for injuries of the upper cervical spine, whereas children in the older age group sustained significantly more injuries of the lower cervical spine. Spinal cord injuries without radiographic abnormalities were only seen in the younger age group. Despite the low incidence of cervical spine injuries in pediatric patients, increased efforts at prevention are demanded because mortality rate (27%) and incidence of neurologic deficits (66%) were dreadfully high in our series.

Intravenous levetiracetam (LEV) has been shown to be effective and safe in treating adults with refractory status epilepticus (SE). We sought to investigate the efficacy and safety of intravenous LEV for pediatric patients with refractory SE. We performed a retrospective medical-record review of pediatric patients who were treated with intravenous LEV for refractory SE. Clinical information regarding age, sex, seizure type, and underlying neurological status was collected. We evaluated other anticonvulsants that were used prior to administration of intravenous LEV and assessed loading dose, response to treatment, and any adverse events from intravenous LEV administration. Fourteen patients (8 boys and 6 girls) received intravenous LEV for the treatment of refractory SE. The mean age of the patients was 4.4 ± 5.5 years (range, 4 days to 14.6 years). Ten of the patients were neurologically healthy prior to the refractory SE, and the other 4 had been previously diagnosed with epilepsy. The mean loading dose of intravenous LEV was 26 ± 4.6 mg/kg (range, 20-30 mg/kg). Seizure termination occurred in 6 (43%) of the 14 patients. In particular, 4 (57%) of the 7 patients younger than 2 years showed seizure termination. No immediate adverse events occurred during or after infusions. The current study demonstrated that the adjunctive use of intravenous LEV was effective and well tolerated in pediatric patients with refractory SE, even in patients younger than 2 years. Intravenous LEV should be considered as an effective and safe treatment option for refractory SE in pediatric patients.

Background Ultrasonography is one of the most common imaging modality to measure dimensions of visceral organs in children. However, the normal limit of size of visceral organs according to age and body habitus has not been specified in the standard textbooks. This might result in under detection of organomegaly in pediatrics population. Objective The objective of this study was to determine the normal range of dimensions for the liver, spleen, and kidney in healthy children. Method This is prospective cross-sectional, hospital-based study done at Tertiary-care teaching hospital. Participants included 272 pediatric subjects (152 male and 120 female) with normal physical or sonographic findings who were examined because of problems unrelated to the measured organs. The subjects were one month to 15 year (180 months) old. All measured organs were sonographically normal. Relationships of the dimensions of these organs with sex, age, body weight and height were investigated. Limits of normal dimensions of these organs were defined. Result Normal length of liver, kidneys and spleen were obtained sonographically for 272 children (152 male [55.9%] and 120 female [44.1%]) in the age group from 1 months to 15 (180 months) years. The mean age was 45.78 months (SD, 44.73). The measured dimensions of all these organs showed highest correlation with height and age so the descriptive analysis of the organ dimensions (mean, minimum, and maximum values, SD and 5th and 95th percentiles) were expressed in 10 age groups along with height range of the included children. The mean length of right kidney was shorter than the left kidney length, and the difference was statistically significant (p = 0.001). Conclusion This study provides practical and comprehensive guide to the normal visceral organ dimension in pediatric population. The normal range limit of the liver, spleen, and kidney determined in this study could be used as a reference in daily practice in local radiology clinics.

Pediatric mild traumatic brain injury (mTBI) is a common and poorly understood injury. Neuroimaging indexes brain injury and outcome after pediatric mTBI, but remains largely unexplored. To investigate the differences in neuroimaging findings in children/youth with mTBI. Measures of behavior, symptoms, time since injury, and age at injury were also considered. A systematic review was conducted up to July 6, 2016. Studies were independently screened by 2 authors and included if they met predetermined eligibility criteria: (1) children/youth (5-18 years of age), (2) diagnosis of mTBI, and (3) use of neuroimaging. Two authors independently appraised study quality and extracted demographic and outcome data. Twenty-two studies met the eligibility criteria, involving 448 participants with mTBI (mean age = 12.7 years ± 2.8). Time postinjury ranged from 1 day to 5 years. Seven different neuroimaging methods were investigated in included studies. The most frequently used method, diffusion tensor imaging (41%), had heterogeneous findings with respect to the specific regions and tracts that showed group differences. However, group differences were observed in many regions containing the corticospinal tract, portions of the corpus callosum, or frontal white-matter regions; fractional anisotropy was increased in 88% of the studies. This review included a heterogeneous sample with regard to participant ages, time since injury, symptoms, and imaging methods which prevented statistical pooling/modelling. These data highlight essential priorities for future research (eg, common data elements) that are foundational to progress the understanding of pediatric concussion.

OBJECTIVE Pediatric patients (age < 18 years) harboring brain arteriovenous malformations (AVMs) are burdened with a considerably higher cumulative lifetime risk of hemorrhage than adults. Additionally, the pediatric population was excluded from recent prospective comparisons of intervention versus conservative management for unruptured AVMs. The aims of this multicenter, retrospective cohort study are to analyze the outcomes after stereotactic radiosurgery for unruptured and ruptured pediatric AVMs. METHODS We analyzed and pooled AVM radiosurgery data from 7 participating in the International Gamma Knife Research Foundation. Patients younger than 18 years of age who had at least 12 months of follow-up were included in the study cohort. Favorable outcome was defined as AVM obliteration, no post-radiosurgical hemorrhage, and no permanently symptomatic radiation-induced changes (RIC). The post-radiosurgery outcomes of unruptured versus ruptured pediatric AVMs were compared, and statistical analyses were performed to identify predictive factors. RESULTS The overall pediatric AVM cohort comprised 357 patients with a mean age of 12.6 years (range 2.8-17.9 years). AVMs were previously treated with embolization, resection, and fractionated external beam radiation therapy in 22%, 6%, and 13% of patients, respectively. The mean nidus volume was 3.5 cm 3 , 77% of AVMs were located in eloquent brain areas, and the Spetzler-Martin grade was III or higher in 59%. The mean radiosurgical margin dose was 21 Gy (range 5-35 Gy), and the mean follow-up was 92 months (range 12-266 months). AVM obliteration was achieved in 63%. During a cumulative latency period of 2748 years, the annual post-radiosurgery hemorrhage rate was 1.4%. Symptomatic and permanent radiation-induced changes occurred in 8% and 3%, respectively. Favorable outcome was achieved in 59%. In the multivariate logistic regression analysis, the absence of prior AVM embolization (p = 0.001) and higher margin dose (p < 0.001) were found to be independent predictors of a favorable outcome. The rates of favorable outcome for patients treated with a margin dose ≥ 22 Gy vs < 22 Gy were 78% (110/141 patients) and 47% (101/216 patients), respectively. A margin dose ≥ 22 Gy yielded a significantly higher probability of a favorable outcome (p < 0.001). The unruptured and ruptured pediatric AVM cohorts included 112 and 245 patients, respectively. Ruptured AVMs had significantly higher rates of obliteration (68% vs 53%, p = 0.005) and favorable outcome (63% vs 51%, p = 0.033), with a trend toward a higher incidence of post-radiosurgery hemorrhage (10% vs 4%, p = 0.07). The annual post-radiosurgery hemorrhage rates were 0.8% for unruptured and 1.6% for ruptured AVMs. CONCLUSIONS Radiosurgery is a reasonable treatment option for pediatric AVMs. Obliteration and favorable outcomes are achieved in the majority of patients. The annual rate of latency period hemorrhage after radiosurgery for both ruptured and unruptured pediatric AVM patients conveys a significant risk until the nidus is obliterated.

Tracheostomy is a procedure that can be performed in any age group, including children under 1year of age. Unfortunately health professionals in Brazil have great difficulty dealing with this condition due to the lack of standard care orientation. This clinical consensus by Academia Brasileira de Otorrinolaringologia Pediátrica (ABOPe) and Sociedade Brasileira de Pediatria (SBP) aims to generate national recommendations on the care concerning tracheostomized children. A group of experts experienced in pediatric tracheostomy (otorhinolaryngologists, intensive care pediatricians, endoscopists, and pediatric pulmonologists) were selected, taking into account the different regions of Brazil and following inclusion and exclusion criteria. The results generated from this document were based on the agreement of the majority of participants regarding the indications, type of cannula, surgical techniques, care, and general guidelines and decannulation. These guidelines can be used as directives for a wide range of health professionals across the country that deal with tracheostomized children.

This study outlined the epidemiological profiles of patients who were admitted to the Pediatric Intensive Care Center at Albert Einstein Israelite Hospital during 2009. Data were retrospectively collected for all patients admitted to the PICC during 2009. A total of 433 medical charts were reviewed, and these data were extracted using the DATAMARTS System and analyzed using the statistical software package STATA, version 11.0. There were no statistically significant differences in regards to patient gender, and the predominant age group consisted of patients between the ages of 1 to 4 years. The average occupancy rate was 69.3% per year, and there was a greater number of admissions during April, August, and October. The average length of stay at the hospital ranged from 9.7 to 19.1 days. Respiratory diseases were the main cause for admission to the Pediatric Intensive Care Center, and the mortality rate of the patients admitted was 1.85%. Respiratory diseases were the most common ailment among patients admitted to the Pediatric Intensive Care Center, and the highest mortality rates were associated with neoplastic diseases.

Outcomes of laryngeal reinnervation with ansa-cervicalis for unilateral vocal fold paralysis (UVFP) may be influenced by age of the patient and time interval between laryngeal nerve injury and reinnervation, suggesting less favorable outcomes in older patients and greater than 2-year time interval after injury. This study examines these issues in the pediatric population. Review of prospectively collected data set of 35 children and adolescents (1-21 years) that underwent ansa-recurrent laryngeal nerve (RLN) laryngeal reinnervation for UVFP. The time from RLN injury to reinnervation averaged 5.0 years (range, 0.8-15.2 years). No correlation was found between age at reinnervation (r = 0.15) and patient- or parent-reported global percentage voice outcome or perceptual ratings. There was slight negative correlation in duration between RLN injury and reinnervation and voice outcomes (r = -0.31). Postoperative voice self/surrogate global percentage rating average was 80.5% (range, 50%-100%), and perceptual rating GRBAS sum score average was 2.9 (range, 0-7). In pediatric ansa-RLN reinnervation for UVFP, no correlation between age at surgery and postoperative outcome was found. Denervation duration showed slight negative correlation, similar to what has been reported in adults, though voice improvement was seen in all patients. © The Author(s) 2015.

Purpose: To present the results of a patient dose evaluation program in pediatric cardiology and propose local diagnostic reference levels (DRLs) for different types of procedure and age range, in addition to suggesting approaches to correlate patient dose values with patient weight. This study was the first conducted in Latin America for pediatric interventional cardiology under the auspices of the International Atomic Energy Agency. Methods: Over three years, the following data regarding demographic and patient dose values were collected: age, gender, weight, height, number of cine series, total number of cine frames, fluoroscopy time (FT), and two dosimetric quantities, dose-areamore » product (DAP) and cumulative dose (CD), at the patient entrance reference point. The third quartile values for FT, DAP, CD, number of cine series, and the DAP/body weight ratio were proposed as the set of quantities to use as local DRLs. Results: Five hundred and seventeen patients were divided into four age groups. Sample sizes by age group were 120 for <1 yr; 213 for 1 to <5 yr; 82 for 5 to <10 yr; and 102 for 10 to <16 yr. The third quartile values obtained for DAP by diagnostic and therapeutic procedures and age range were 1.17 and 1.11 Gy cm{sup 2} for <1 yr; 1.74 and 1.90 Gy cm{sup 2} for 1 to <5 yr; 2.83 and 3.22 Gy cm{sup 2} for 5 to <10 yr; and 7.34 and 8.68 Gy cm{sup 2} for 10 to <16 yr, respectively. The third quartile value obtained for the DAP/body weight ratio for the full sample of procedures was 0.17 (Gy cm{sup 2}/kg) for diagnostic and therapeutic procedures. Conclusions: The data presented in this paper are an initial attempt at establishing local DRLs in pediatric interventional cardiology, from a large sample of procedures for the standard age bands used in Europe, complemented with the values of the ratio between DAP and patient weight. This permits a rough estimate of DRLs for different patient weights and the refining of these values for the age bands when there may be large differences in child size. These DRLs were obtained at the largest pediatric hospital in Chile, with an active optimization program, and could be used by other hospitals in the Latin America region to compare their current patient dose values and determine whether corrective action is appropriate.« less

Current efforts to reconstruct organ doses in children undergoing diagnostic imaging or therapeutic interventions using ionizing radiation typically rely upon the use of reference anthropomorphic computational phantoms coupled to Monte Carlo radiation transport codes. These phantoms are generally matched to individual patients based upon nearest age or sometimes total body mass. In this study, we explore alternative methods of phantom-to-patient matching with the goal of identifying those methods which yield the lowest residual errors in internal organ volumes. Various thoracic and abdominal organs were segmented and organ volumes obtained from chest-abdominal-pelvic (CAP) computed tomography (CT) image sets from 38 pediatric patients ranging in age from 2 months to 15 years. The organs segmented included the skeleton, heart, kidneys, liver, lungs and spleen. For each organ, least-squared regression lines, 95th percentile confidence intervals and 95th percentile prediction intervals were established as a function of patient age, trunk volume, estimated trunk mass, trunk height, and three estimates of the ventral body cavity volume based on trunk height alone, or in combination with circumferential, width and/or breadth measurements in the mid-chest of the patient. When matching phantom to patient based upon age, residual uncertainties in organ volumes ranged from 53% (lungs) to 33% (kidneys), and when trunk mass was used (surrogate for total body mass as we did not have images of patient head, arms or legs), these uncertainties ranged from 56% (spleen) to 32% (liver). When trunk height is used as the matching parameter, residual uncertainties in organ volumes were reduced to between 21 and 29% for all organs except the spleen (40%). In the case of the lungs and skeleton, the two-fold reduction in organ volume uncertainties was seen in moving from patient age to trunk height—a parameter easily measured in the clinic. When ventral body cavity volumes were used, residual uncertainties were lowered even further to a range of between 14 and 20% for all organs except the spleen, which continued to remain at around 40%. The results of this study suggest that a more anthropometric pairing of computational phantom to individual patient based on simple measurements of trunk height and possibly mid-chest circumference or thickness (where influences of subcutaneous fat are minimized) can lead to significant reductions in organ volume uncertainties: ranges of 40-50% (based on patient age) to between 15 and 20% (based on body cavity volumes tied to trunk height). An expanded series of non-uniform rational B-spine (NURBS) pediatric phantoms are being created at the University of Florida to allow the full application of this new approach in pediatric medical imaging studies.

Apnea is a known complication of pediatric seizures, but patient factors that predispose children are unclear. We seek to quantify the risk of apnea attributable to midazolam and identify additional risk factors for apnea in children transported by paramedics for out-of-hospital seizure. This is a 2-year retrospective study of pediatric patients transported by paramedics to 2 tertiary care centers. Patients were younger than 15 years and transported by paramedics to the pediatric emergency department (ED) for seizure. Patients with trauma and those with another pediatric ED diagnosis were excluded. Investigators abstracted charts for patient characteristics and predefined risk factors: developmental delay, treatment with antiepileptic medications, and seizure on pediatric ED arrival. Primary outcome was apnea defined as bag-mask ventilation or intubation for apnea by paramedics or by pediatric ED staff within 30 minutes of arrival. There were 1,584 patients who met inclusion criteria, with a median age of 2.3 years (Interquartile range 1.4 to 5.2 years). Paramedics treated 214 patients (13%) with midazolam. Seventy-one patients had apnea (4.5%): 44 patients were treated with midazolam and 27 patients were not treated with midazolam. After simultaneous evaluation of midazolam administration, age, fever, developmental delay, antiepileptic medication use, and seizure on pediatric ED arrival, 2 independent risk factors for apnea were identified: persistent seizure on arrival (odds ratio [OR]=15; 95% confidence interval [CI] 8 to 27) and administration of field midazolam (OR=4; 95% CI 2 to 7). We identified 2 risk factors for apnea in children transported for seizure: seizure on arrival to the pediatric ED and out-of-hospital administration of midazolam.

Unintentional pediatric cocaine exposures are rare but concerning due to potentially serious complications such as seizures, dysrhythmias, and death. The objectives were to assess the demographic and clinical characteristics of pediatric cocaine exposures reported to the California Poison Control System. This is a retrospective study of all confirmed pediatric (< 6 years of age) cocaine exposures reported to the California Poison Control System from January 1, 1997-September 30, 2010. Case narratives were reviewed for patient demographics, exposure details, clinical effects, therapy, hospitalization, and final outcome. Of the 86 reported pediatric cocaine exposures, 36 had positive urine drug testing and were included in the study cohort. The median age at presentation was 18 months (range: 0-48 months), and 56% were male (n = 20). The most common clinical manifestations were tachycardia and seizures. The most common disposition was admission to an intensive care unit (n = 14; 39%). Eleven cases (31%) were classified as having a major effect as per American Association of Poison Control Centers case coding guidelines. One child presented in asystole with return of spontaneous circulation after cardiopulmonary resuscitation and multiple vasoactive medications. The proportion of cocaine exposures with serious (moderate or major) outcomes (66.7%; 95% confidence interval 50.3-79.8%) was higher than other pediatric poisonings reported to the American Association of Poison Control Centers during the study period (0.88%; 95% confidence interval 0.87-0.88). Although pediatric cocaine exposures are rare, they result in more severe outcomes than most unintentional pediatric poisonings. Practitioners need to be aware of the risk of recurrent seizures and cardiovascular collapse associated with cocaine poisoning. Copyright © 2017 Elsevier Inc. All rights reserved.

OBJECT The purpose of this study focusing on fusion rate was to determine the efficacy of recombinant human bone morphogenetic protein-2 (rhBMP-2) use in posterior instrumented fusions of the craniocervical junction in the pediatric population. The authors previously reported the short-term (mean follow-up 11 months) safety and efficacy of rhBMP-2 use in the pediatric age group. The present study reports on their long-term results (minimum of 12 months' follow-up) and focuses on efficacy. METHODS The authors performed a retrospective review of 83 consecutive pediatric patients who had undergone posterior occipitocervical or atlantoaxial spine fusion at Texas Children's Hospital or Riley Children's Hospital during the period from October 2007 to October 2012. Forty-nine patients were excluded from further analysis because of death, loss to follow-up, or lack of CT evaluation of fusion at 12 or more months after surgery. Fusion was determined by postoperative CT scan at a minimum of 12 months after surgery. The fusion was graded and classified by a board-certified fellowship-trained pediatric neuroradiologist. Other factors, such as patient age, diagnosis, number of vertebral levels fused, use of allograft or autograft, dosage of bone morphogenetic protein (BMP), and use of postoperative orthosis, were recorded. RESULTS Thirty-four patients had a CT scan at least 12 months after surgery. The average age of the patients at surgery was 8 years, 1 month (range 10 months-17 years). The mean follow-up was 27.7 months (range 12-81 months). There were 37 fusion procedures in 34 patients. Solid fusion (CT Grade 4 or 4-) was achieved in 89.2% of attempts (33 of 37), while incomplete fusion or failure of fusion was seen in 10.8%. Based on logistic regression analysis, there was no significant association between solid fusion and age, sex, BMP dose, type of graft material, use of postoperative orthosis, or number of levels fused. Three of 34 patients (8.8%) required revision surgery. CONCLUSIONS Despite the large number of adult studies reporting positive effects of BMP on bone fusion, our long-term outcomes using rhBMP-2 in the pediatric population suggest that rates of fusion failure are higher than observed in contemporary adult and pediatric reports of occipitocervical and atlantoaxial spine fusions.

Traumatic brain injury (TBI) is a common condition affecting children all over the world, and it represents a global public health concern. It is unclear how geopolitical, societal, and ethnic differences may influence the nature of TBI among children. A comprehensive literature search was conducted incorporating studies with hospital-, regional-, or country-specific pediatric TBI epidemiology data published between 1995 and 2015. Incidence, age, severity, mechanism of injury, and other relevant injury characteristics were extracted and compared across diverse geographic regions. Thirty articles met inclusion criteria, incorporating TBI data from more than 165,000 children on 5 continents. The worldwide incidence of pediatric TBI ranges broadly and varies greatly by country, with most reporting a range between 47 and 280 per 100,000 children. After the age of 3, male children suffered higher rates of TBI than females. A bimodal age distribution is often described, with very young children (0-2 years) and adolescents (15-18) more commonly injured. Mild TBI (Glasgow Coma Scale ≥13) constitutes more than 80% of injuries, and up to 90% of all injuries are associated with negative imaging. Only a small fraction (<10%) requires surgical intervention. Independent of country or region of origin, the vast majority of children suffering TBI achieve a good clinical outcome. Hospital admission rates vary widely, with U.S. patients more commonly admitted than those from other countries. Falls and motor vehicle collisions (MVCs) represent the majority of injury mechanisms. In Africa and Asia, pedestrians were most commonly injured in MVCs, while vehicle occupants were more likely involved among Australian, European, and U.S. For children, nonaccidental trauma was prevalent in developing and developed nations alike. TBI is a relatively common entity stretching across traditional geographic and demographic boundaries and affecting pediatric populations worldwide. Continued civil infrastructure development and public health policy reforms may help to reduce the societal burden of pediatric TBI. Copyright © 2016 Elsevier Inc. All rights reserved.

There is a need for updated radiation dose estimates in pediatric fluoroscopy given the routine use of new dose-saving technologies and increased radiation safety awareness in pediatric imaging. To estimate effective doses for standardized pediatric upper gastrointestinal (UGI) examinations at our institute using direct dose measurement, as well as provide dose-area product (DAP) to effective dose conversion factors to be used for the estimation of UGI effective doses for boys and girls up to 10 years of age at other centers. Metal oxide semiconductor field-effect transistor (MOSFET) dosimeters were placed within four anthropomorphic phantoms representing children ≤10 years of age and exposed to mock UGI examinations using exposures much greater than used clinically to minimize measurement error. Measured effective dose was calculated using ICRP 103 weights and scaled to our institution's standardized clinical UGI (3.6-min fluoroscopy, four spot exposures and four examination beam projections) as determined from patient logs. Results were compared to Monte Carlo simulations and related to fluoroscope-displayed DAP. Measured effective doses for standardized pediatric UGI examinations in our institute ranged from 0.35 to 0.79 mSv in girls and were 3-8% lower for boys. Simulation-derived and measured effective doses were in agreement (percentage differences <19%, T > 0.18). DAP-to-effective dose conversion factors ranged from 6.5 ×10(-4) mSv per Gy-cm(2) to 4.3 × 10(-3) mSv per Gy-cm(2) for girls and were similarly lower for boys. Using modern fluoroscopy equipment, the effective dose associated with the UGI examination in children ≤10 years at our institute is < 1 mSv. Estimations of effective dose associated with pediatric UGI examinations can be made for children up to the age of 10 using the DAP-normalized conversion factors provided in this study. These estimates can be further refined to reflect individual hospital examination protocols through the use of direct organ dose measurement using MOSFETs, which were shown to agree with Monte Carlo simulated doses.

Graves' disease (GD) accounts for 10-15% of thyroid disorders in patients less than 18 years of age. It is the most common cause of thyrotoxicosis in children and accounts for at least 95% of cases in children. Pediatric Treatment of Graves' disease consists of anti-thyroid drugs, radioactive iodide and thyroidectomy but the optimal treatment of GD in children is still controversial. To review treatment outcome of pediatric Graves' disease in Albania. Descriptive review of 15 children with Graves' disease, diagnosed from Jan.2007 to Dec. 2013, at the Division of Pediatric Endocrinology, Department of Pediatrics, University Hospital Centre "Mother Teresa", Albania was performed. All patients, mean age 10.56 ± 3.37 years, (range 2.02-16.09 years) were presented with goiter and increased serum FT4, mean 39.80 ± 16.02 ng/mL, (range 21.0-74.70 ng/mL), serum FT3, mean 12.98 ± 3.45 pg/mL, (range 6.90 -17.90 pg/mL) and suppressed TSH levels, mean 0.02 ± 0.01 mUI/L, (range 0.01-0.05 mUI/L). Anti TSH Receptor were positive in 100% of patients mean value 6.51 ± 3.61 UI/mL (range 1.63 - 14.10 UI/mL). Anti-thyroglobulin and Anti-TPO antibodies were positive in 60% and 46.6% respectively. Clinical course of 15 patients after treatment with anti-thyroid drugs mainly MMI for 3.19 ± 1.48 (range 0.60 - 6.20) years is as follows: seven (46.66%) underwent remission, five out of seven (71.41%) who underwent remission, relapsed. Three of them (20%) were treated with I(131), and two (13.3%) underwent to total thyroidectomy. MMI was the most common first line therapy in the presented patients with Graves' disease. Remission rate was 46.66% after an average 1.48 ± 0.71 years (range 0.60 - 2.70 years) of treatment with anti-thyroid drugs. Remission period was 2.70 ± 0.36 years (2.1 - 3.1 years) Relapse occurred in 71.41% of patient. I(131) and thyroidectomy were used as second line therapy in the present study.

The objective of this study is to validate the Inoue method so that it would be the preferential choice in determining glomerular filtration rate (GFR) in Philippine pediatrics. The study consisted of 36 patients ranging from ages 2 months to 19 years old. The subjects used were those who were previously subjected to in-vitro method. The scintigrams of the invitro method was obtained and processed for split percentage uptake and for parameters needed to obtain Inoue GFR. The result of this paper correlates the Inoue GFR and In-vitro method (r = 0.926). Thus, Inoue method is a viable, simple, and practical technique in determining GFR in pediatric patients.

Aim Outcomes for pediatric out-of-hospital cardiac arrest (OHCA) are poor. Our objective was to determine temporal trends in incidence and mortality for pediatric OHCA. Methods Adjusted incidence and hospital mortality rates of pediatric non-traumatic OHCA patients from 2007-2012 were analyzed using the 9 region Resuscitation Outcomes Consortium - Epidemiological Registry (ROC-Epistry) database. Children were divided into 4 age groups: perinatal (< 3 days), infants (3 days - 1 year), children (1 - 11 years), and adolescents (12 - 19 years). ROC regions were analyzed post-hoc. Results We studied 1,738 children with OHCA. The age- and sex-adjusted incidence rate of OHCA was 8.3 per 100,000 person-years (75.3 for infants vs. 3.7 for children and 6.3 for adolescents, per 100,000 person-years, p<0.001). Incidence rates differed by year (p<0.001) without overall linear trend. Annual survival rates ranged from 6.7-10.2%. Survival was highest in the perinatal (25%) and adolescent (17.3%) groups. Stratified by age group, survival rates over time were unchanged (all p>0.05) but there was a non-significant linear trend (1.3% increase) in infants. In the multivariable logistic regression analysis, infants, unwitnessed event, initial rhythm of asystole, and region were associated with worse survival, all p<0.001. Survival by region ranged from 2.6-14.7%. Regions with the highest survival had more cases of EMS-witnessed OHCA, bystander CPR, and increased EMS-defibrillation (all p<0.05). Conclusions Overall incidence and survival of children with OHCA in ROC regions did not significantly change over a recent 5 year period. Regional variation represents an opportunity for further study to improve outcomes. PMID:27565862

The purpose of this work was to investigate the clinical manifestations and diagnostic range of malignant entities presenting as a nasal mass in the pediatric population. A retrospective cohort analysis was conducted at a specialty hospital and a tertiary care university hospital. Patients aged between birth and 18 years and diagnosed with a malignancy that arose within the nasal cavity between the years 1991 and 2006 were included. This institution-specific patient group was compared with a similar cohort of patients extracted from the national Surveillance Epidemiology and End Results database. The main outcome measures were the incidence, presentation, and diagnoses of nasal cancer presenting in this population. Sixteen patients with nasal malignancies presented institutionally in the defined pediatric age group. Patient age at the time of diagnosis ranged from 7 months to 17 years, with a slight male predominance. The main presenting symptoms were unilateral nasal congestion and ophthalmologic complaints. The median time from presentation to diagnosis was 7 weeks; patients who presented with nonspecific complaints, such as nasal obstruction, headache, and fatigue, were given a diagnosis, on average, later than those who presented with focal manifestations. Nationwide, 47 patients were identified from the Surveillance Epidemiology and End Results database. In both subject groups, the most common diagnoses were rhabdomyosarcoma (37.5% institutionally and 23% in the Surveillance Epidemiology and End Results group) and esthesioneuroblastoma (25% institutionally and 28% Surveillance Epidemiology and End Results). In the Surveillance Epidemiology and End Results cohort, the overall mean survival rate was 188 months. Nasal cancer in the pediatric population often presents with nonspecific signs and symptoms, and a high index of suspicion is necessary for a timely diagnosis. Soft tissue sarcomas are expectedly common. The relative high frequency of esthesioneuroblastoma is particularly noteworthy.

Studies from Nigeria on pediatric otorhinolaryngology (ORL) emergencies are rare in literature with most focusing on emergencies involving individual systems. The aim of this study is to determine the prevalence of all ORL emergencies among children in our region to provide a baseline data for future health planning. This is a 1-year retrospective cross-sectional study of patients aged 16 years and below presenting to the Accident and Emergency Department of the Jos University Teaching Hospital, Jos, Nigeria. A total of 203 otolaryngology emergencies were attended of which 129 (63.5%) were pediatric emergencies. Records of 87 patients were retrievable with age range 2 months to 15 years (mean 3.44 years; standard deviation ± 3.35). There were 55 males and 32 females with a male to female ratio of 1.7:1. The majority of cases were aged under 5 years (64; 73.6%). Acute tonsillitis accounted for 32 (36.7%) cases with 6 (6.9%) having peritonsillar abscesses. Acute pharyngitis accounted for 11 (12.6%) presentations followed closely by foreign bodies (FBs) in the ear with 10 (11.5%) presentations. FB in the throat occurred in 4 (4.6%) patients who had removal under general anesthesia. Three (3.4%) cases of maxillofacial injuries occurred as a result of insurgent terror attacks and 3.4% presented following corrosive substance ingestion. Conservative management was commenced in 76 (87.4%) patients, 23 (26.4%) had surgery with 68 (78.2%) admitted and discharged, 18 (20.7%) treated as outpatients, and 1 (1.1%) died on admission. Otolaryngologists attended most (95.4%) patients. Pediatric ORL emergencies are common in our region involving a wide range of pathologies. Expansion is required in the ORL training of the emergency room physician to enhance emergency services.

Aim: This study aimed at identifying risk factors related to pediatric burns mortality in a middle income country such as Ghana. Methods: The data for the three years retrospective study (May 2009 – April 2012) was obtained from the pediatric burn admissions records and patients’ folders of the Reconstructive Plastic Surgery & Burns Unit (RPSBU), Komfo Anokye Teaching Hospital (KATH), Ghana. Data retrieved included: Demographic features, Total Burned Surface Area (TBSA) incurred; Aetiology of burns; Duration of the admission; Outcome of admission; Part of the body affected and Cost incurred. Ethical approval for this study was obtained from the KNUST-SMS/KATH Committee on Human Research, Publications and Ethics. Data analyses were performed with SPSS 17.0 version. Results: Information on 197 patients was completely retrieved for the study. Burns mortality rate for the study was identified to be 21.3% (N=42). The mean age of the 42 dead patients was 3.7±0.3 years, ranging from 0-13 years, while, males (54.8%, N= 23) outnumbered females (45.2%, N=19). The TBSA burned interquartile range was 48%. In terms of etiology of burns Scald (73.8%, N=31) was the commonest cause of injury. Mortality risk factors identified were Age <6 years (P=0.028); Scald especially hot water and soup (P=0.016); TBSA >36% (P=0.028) and Inhalation injury (P=0.040). Conclusion: Age, scald, TBSA and Inhalation Injury were identified as pediatric burns mortality risk factors in a developing country such as Ghana’s RPSBU. These identified factors will serve as a guideline for plastic surgeons and other health professionals practicing in countries such as Ghana. PMID:23875121

To evaluate and to obtain analytic formulation for the calculation of the effective dose and associated cancer risk using the EOS microdose protocol for scoliotic pediatric patients undergoing full spine imaging at different age of exposure; to demonstrate the microdose protocol capable of delivering lesser radiation dose and hence of further reducing cancer risk induction when compared with the EOS low dose protocol; to obtain cumulative effective dose and cancer risk for both genders scoliotic pediatrics of US and Hong Kong population using the microdose protocol. Organ absorbed doses of full spine exposed scoliotic pediatric patients have been simulated with the use of EOS microdose protocol imaging parameters input to the Monte Carlo software PCXMC. Gender and age specific effective dose has been calculated with the simulated organ absorbed dose using the ICRP-103 approach. The associated radiation induced cancer risk, expressed as lifetime attributable risk (LAR), has been estimated according to the method introduced in the Biological Effects of Ionizing Radiation VII report. Values of LAR have been estimated for scoliotic patients exposed repetitively during their follow up period at different age for US and Hong Kong population. The effective doses of full spine imaging with simultaneous posteroanterior and lateral projection for patients exposed at the age between 5 and 18 years using the EOS microdose protocol have been calculated within the range of 2.54-14.75 μSv. The corresponding LAR for US and Hong Kong population was ranged between 0.04 × 10 -6 and 0.84 × 10 -6 . Cumulative effective dose and cancer risk during follow-up period can be estimated using the results and are of information to patients and their parents. With the use of computer simulation and analytic formulation, we obtained the cumulative effective dose and cancer risk at any age of exposure for pediatric patients of US and Hong Kong population undergoing repetitive microdose protocol full spine imaging. Girls would be at a statistically significant higher cumulative cancer risk than boys undergoing the same microdose full spine imaging protocol and the same follow-up schedule.

Pediatric heart transplantation (HT) is resource intensive. Event-driven pediatric databases do not capture data on resource use. The objective of this study was to evaluate resource utilization and identify associated factors during initial hospitalization for pediatric HT. This multicenter retrospective cohort study utilized the Pediatric Health Information Systems database (43 children's hospitals in the United States) of children ≤19 years of age who underwent transplant between January 2007 and July 2013. Demographic variables including site, payer, distance and time to center, clinical pre- and post-transplant variables, mortality, cost, and charge were the data collected. Total length of stay (LOS) and charge for the initial hospitalization were used as surrogates for resource use. Charges were inflation adjusted to 2013 dollars. Of 1,629 subjects, 54% were male, and the median age at HT was 5 years (IQR [interquartile range] 0 to 13). The median total and intensive care unit LOS were 51 (IQR 23 to 98) and 23 (IQR 9 to 58) days, respectively. Total charge and cost for hospitalization were $852,713 ($464,900 to $1,609,300) and $383,600 ($214,900 to $681,000) respectively. Younger age, lower volume center, southern region, and co-morbidities before transplant were associated with higher resource use. In later years, charges increased despite shorter LOS. In conclusion, this large multicenter study provides novel insight into factors associated with resource use in pediatric patients having HT. Peritransplant morbidities are associated with increased cost and LOS. Reducing costs in line with LOS will improve health-care value. Regional and center volume differences need further investigation for optimizing value-based care and efficient use of scarce resources. Copyright © 2018 Elsevier Inc. All rights reserved.

Visceral adiposity index (VAI) is a mathematical model associated with cardiometabolic risk in adults, but studies on children failed to support this association. Our group has proposed a pediatric VAI model using pediatric ranges, but it has not yet been evaluated and needs further adjustments. The objective of this study was to further adjust the proposed pediatric VAI by age, creating a new pediatric metabolic index (PMI), and assess the correlation of the PMI with insulin resistance indexes and hepatic enzymes. A cross-sectional design with data from 396 children (age 5 to 17 years) was analyzed with a generalized linear model to find the coefficients for triglycerides, high-density-lipoprotein cholesterol, and waist circumference-body mass index quotient. The model was constructed according to sex and age and designated PMI. A cross-validation analysis was performed and a receiver operating characteristic curve was used to determine cut-off points. Significant moderate correlation was found between PMI and homeostatic model assessment of insulin resistance (HOMA-IR) ( r = 0.452; P = .003), Matsuda ( r = -0.366; P = .019), alanine aminotransferase ( r = 0.315, P = .045), and γ-glutamyltransferase ( r = 0.397; P = .010). A PMI score >1.7 was considered as risk. PMI correlates with HOMA-IR, Matsuda, and hepatic enzymes. It could be helpful for identifying children at risk for cardiometabolic diseases. ALT = alanine transaminase BMI = body mass index GGT = γ-glutamyltransferase HDL-C = high-density-lipoprotein cholesterol HOMA-IR = homeostatic model assessment of insulin resistance hs-CRP = high sensitivity C-reactive protein ISI = insulin sensitivity index NAFLD = nonalcoholic fatty liver disease PMI = pediatric metabolic index QUICKI = quantitative insulin sensitivity check index ROC = receiver operating characteristic TG = triglyceride TNF-α = tumor necrosis factor-alpha VAI = visceral adiposity index VAT = visceral adipose tissue WC = waist circumference.

Thyroid hormone concentrations fluctuate during growth and development. To accurately diagnose thyroid disease in pediatric patients, reference intervals (RIs) should be established with appropriate age groups from an adequate number of healthy subjects using the most exact methods possible. Obtaining statistically useful numbers of healthy patients is particularly challenging for pediatric populations. The objective of this study was to determine non-parametric RIs for free thyroxine (fT4) and free triiodothyronine (fT3) using equilibrium dialysis-high performance liquid chromatography-tandem mass spectrometry with over 2200 healthy children 6 months-17 years of age. Subjects were negative for both thyroglobulin and thyroid peroxidase autoantibodies and had normal thyrotropin concentrations. The study included 2213 children (1129 boys and 1084 girls), with at least 120 subjects (average of 125) from each year of life, except for the 6 month to 1 year age group (n=96). Non-parametric RIs (95th percentile) for fT4 were: 18.0-34.7 pmol/L (boys and girls, 6 months-6 years) and 14.2-25.7 pmol/L (boys and girls, 7-17 years). RIs for fT3 were: 5.8-13.1 pmol/L (girls, 6 months-6 years); 5.7-11.8 pmol/L (boys, 6 months-6 years); 5.7-10.0 pmol/L (boys and girls, 7-12 years); 4.5-8.6 pmol/L (girls, 13-17 years); and 5.2-9.4 pmol/L (boys, 13-17 years). Numerous significant differences were observed between pediatric age groups and previously established adult ranges. This emphasizes the need for well-characterized RIs for thyroid hormones in the pediatric population.

The use of ventricular assist devices has increased dramatically in adult heart failure patients. However, the overall use, outcome, comorbidities, and resource utilization of ventricular assist devices in pediatric patients have not been well described. We sought to demonstrate that the use of ventricular assist devices in pediatric patients has increased over time and that mortality has decreased. A retrospective study of the Pediatric Health Information System database was performed for patients 20 years old or younger undergoing ventricular assist device placement from 2000 to 2010. None. Four hundred seventy-five pediatric patients were implanted with ventricular assist devices during the study period: 69 in 2000-2003 (era 1), 135 in 2004-2006 (era 2), and 271 in 2007-2010 (era 3). Median age at ventricular assist device implantation was 6.0 years (interquartile range, 0.5-13.8), and the proportion of children who were 1-12 years old increased from 29% in era 1 to 47% in era 3 (p = 0.002). The majority of patients had a diagnosis of cardiomyopathy; this increased from 52% in era 1 to 72% in era 3 (p = 0.003). Comorbidities included arrhythmias (48%), pulmonary hypertension (16%), acute renal failure (34%), cerebrovascular disease (28%), and sepsis/systemic inflammatory response syndrome (34%). Two hundred forty-seven patients (52%) underwent heart transplantation and 327 (69%) survived to hospital discharge. Hospital mortality decreased from 42% in era 1 to 25% in era 3 (p = 0.004). Median hospital length of stay increased (37 d [interquartile range, 12-64 d] in era 1 vs 69 d [interquartile range, 35-130] in era 3; p < 0.001) and median adjusted hospital charges increased ($630,630 [interquartile range, $227,052-$853,318] in era 1 vs $1,577,983 [interquartile range, $874,463-$2,280,435] in era 3; p < 0.001). Factors associated with increased mortality include age less than 1 year (odds ratio, 2.04; 95% CI, 1.01-3.83), acute renal failure (odds ratio, 2.1; 95% CI, 1.26-3.65), cerebrovascular disease (odds ratio, 2.1; 95% CI, 1.25-3.62), and extracorporeal membrane oxygenation (odds ratio, 3.16; 95% CI, 1.79-5.60). Ventricular assist device placement in era 3 (odds ratio, 0.3; 95% CI, 0.15-0.57) and a diagnosis of cardiomyopathy (odds ratio, 0.5; 95% CI, 0.32-0.84), were associated with decreased mortality. Large-volume centers had lower mortality (odds ratio, 0.55; 95% CI, 0.34-0.88), lower use of extracorporeal membrane oxygenation, and higher charges. The use of ventricular assist devices and survival after ventricular assist device placement in pediatric patients have increased over time, with a concomitant increase in resource utilization. Age under 1 year, certain noncardiac morbidities, and the use of extracorporeal membrane oxygenation are associated with worse outcomes. Lower mortality was seen at larger volume ventricular assist device centers.

Though vedolizumab has received regulatory approval for the treatment of Crohn's disease (CD) and ulcerative colitis (UC) in adults, there is increasing off-label use in children. To describe the experience with vedolizumab in pediatric inflammatory bowel disease (IBD) patients at 3 tertiary IBD centers and examine predictors of remission. A retrospective review identified pediatric IBD patients (age < 18 yrs) receiving vedolizumab. Data on demographics, disease behavior, location, activity, and previous treatments/surgeries were collected. Disease activity was assessed using the weighted pediatric CD activity index or pediatric UC activity index. Primary outcome was week 14 remission, defined as pediatric UC activity index <10 or weighted pediatric CD activity index <12.5. Descriptive statistics and univariate analyses were performed to examine associations of clinical characteristics with efficacy. Fifty-two patients, 58% CD and 42% UC, initiated vedolizumab between June 2014 and August 2015. Median age at vedolizumab initiation was 14.9 (range 7-17) years. Ninety percent had failed ≥1 anti-tumor necrosis factor (TNF) agent. Week 14 remission rates for UC and CD were 76% and 42%, respectively (P < 0.05). Eighty percent of anti-TNF-naive patients experienced week 14 remission. At week 22, anti-TNF-naive patients had higher remission rates than TNF-exposed patients (100% versus 45%, P = 0.04). There were no infusion reactions or serious adverse events/infections. Our results suggest that vedolizumab is efficacious and safe in pediatric IBD patients, with UC patients experiencing earlier and higher rates of remission than CD patients. Anti-TNF-naive patients experienced higher remission rates than those with anti-TNF exposure. Controlled clinical trial data are needed to confirm these observations.

The PedsQL (Pediatric Quality of Life Inventory) is a modular instrument designed to measure health-related quality of life (HRQOL) and disease-specific symptoms in children and adolescents ages 2-18. The PedsQL Multidimensional Fatigue Scale was designed as a generic symptom-specific instrument to measure fatigue in pediatric patients ages 2-18. Since a sizeable number of pediatric patients prefer to remain with their pediatric providers after age 18, the objective of the present study was to determine the feasibility, reliability, and validity of the PedsQL Multidimensional Fatigue Scale in young adults. The 18-item PedsQL Multidimensional Fatigue Scale (General Fatigue, Sleep/Rest Fatigue, and Cognitive Fatigue domains), the PedsQL 4.0 Generic Core Scales Young Adult Version, and the SF-8 Health Survey were completed by 423 university students ages 18-25. The PedsQL Multidimensional Fatigue Scale evidenced minimal missing responses, achieved excellent reliability for the Total Scale Score (alpha = 0.90), distinguished between healthy young adults and young adults with chronic health conditions, was significantly correlated with the relevant PedsQL 4.0 Generic Core Scales and the SF-8 standardized scores, and demonstrated a factor-derived structure largely consistent with the a priori conceptual model. The results demonstrate the measurement properties of the PedsQL Multidimensional Fatigue Scale in a convenience sample of young adult university students. The findings suggest that the PedsQL Multidimensional Fatigue Scale may be utilized in the evaluation of fatigue for a broad age range.

Knowledge of the spectrum and frequencies of pediatric emergencies presenting to an emergency department (ED) of individual developing countries is vital in optimizing the quality of care delivered locally. A prospective 6 wk review of all pediatric (< 18 y) attendees to an urban ED was done, with patient age, presenting complaints, diagnoses, time of arrival and disposition recorded. Complete data were available on 1172 patients, with an age range of 4 d to 18 y (mean +/- SD 6.9 +/- 5.6 y); 43% were aged < or = 4 y. The main presenting complaints were injuries (26.9%), fever (24%) and breathing difficulties (16.6%). The most common diagnosis was minor trauma (24.2%), with soft-tissue injuries predominating (80.6%). The other diagnoses were asthma (12.6%), upper respiratory infections (12.1%), other infections (12.1%) and gastroenteritis (11.8%). Equal proportions of patients were seen throughout the day. 25% of patients were admitted. Young age (< 1 y); presence of past medical history, general practitioner referrals, diagnosis of bronchiolitis and pneumonia were significantly associated with risk of admission. A wide spectrum of paediatric illnesses was seen in the ED, with an overrepresentation of young children. This supports the decision to have either a separate pediatric ED or paediatric residents on the staff. The training curricula should emphasize the management of pediatric trauma, infections and asthma. Alternatively, developing guidelines for the five most common presenting complaints would account for 82% of all attendees and could be directed towards all staff on the ED.

Intact knee extensor mechanism is required for the normal function of the lower extremity. Patellar tendon rupture is a relatively rare injury with peak age incidence around 40 years and usually occurs midsubstance. The occurrence of pure patellar tendon rupture without bony avulsion is an extremely rare injury in the pediatric population with few cases reported in the literature with limited information regarding frequency, complications, and outcomes in children. However, due to increased participation in sports and high-energy recreational activities during childhood, the frequency of such injuries has progressively increased. To evaluate the frequency of pediatric patellar tendon rupture injuries and describe the radiological findings, treatment modalities, and outcome of such injuries. Demographic and clinical data on a series of patients who sustained patellar tendon rupture were reviewed. These data included age at time of injury, sex, laterality, mechanism of injury, associated injuries, complications, presence or absence of Osgood-Schlatter disease, diagnostic imaging such as plain radiographs and magnetic resonance images (MRI), surgical technique, method of fixation, period of postoperative immobilization, total duration of physiotherapy, time to return to sports activities and follow-up duration. Insall-Salvati ratio was calculated on the preoperative lateral x-ray. The functional outcome was evaluated with regard to final knee active range of motion (AROM), manual quadriceps muscle testing, and presence or the absence of terminal extension lag. Clinical outcome rating using knee society score (KSS) was performed and functional outcome was further classified according to the calculated score. Five male patients with patellar tendon rupture (7%) were identified among 71 pediatric patients who sustained acute traumatic injury of the knee extensor mechanism. The mean age at the time of injury was 13.6 years (range: 12-15 years). The injury occurred in relation to sports activities in 4 patients. Osteogenesis imperfecta and Osgood-Schlatter disease were identified in 2 patients. High riding patella is the hallmark diagnostic sign detected in plain x-ray with preoperative Insall-Salvati ratio ranged from 1.7 to 2.5. Three patients had pure soft tissue avulsion distally from the proximal tibia, 1 patient had pure soft tissue avulsion proximally from the inferior patellar pole, and 1 patient with midsubstance tendinous disruption. No associated intra-articular lesions were identified. Suture bridge double row technique, transpatellar suturing, and transosseous suturing through the proximal tibia were used for patellar tendon reinsertion. After a mean follow-up period of 18. 4 weeks (range: 10-30 weeks), patients achieved AROM ranging from 0 to 120° to 0-137° without terminal extension lag. The mean time to return to sports activity was 22 weeks (range: 13-30 weeks). Quadriceps muscle strength was 5/5 at the final follow-up visit in all patients; however, relative muscle atrophy was noted in comparison to the other side in one patient. The mean KSS was 91.8 points (range: 79-100 points) with excellent outcome in 4 patients and good outcome in 1 patient. Patellar tendon rupture is rare in the pediatric population and represents 7% of pediatric patients who sustained acute traumatic injury of the knee extensor mechanism. Ruptures may occur midsubstance, or from proximal or distal insertions. High riding patella is the hallmark diagnostic sign for such injury. Although rare, it is considered a serious injury that necessitates early diagnosis and surgical intervention. Functional range of motion was obtained in all patients with different modalities of treatment. Copyright © 2017 Elsevier Ltd. All rights reserved.

Characteristics and Associated Comorbidities of Pediatric Dental Patients Treated under General Anesthesia.

Delfiner, Alexandra; Myers, Aaron; Lumsden, Christie; Chussid, Steve; Yoon, Richard

To describe characteristics and identify common comorbidities of children receiving dental treatment under general anesthesia at Children's Hospital of New York-Presbyterian. Electronic medical records of all children that received dental treatment under general anesthesia through the Division of Pediatric Dentistry from 2012-2014 were reviewed. Data describing patient characteristics (age, sex, race/ethnicity, insurance carrier, and American Society of Anesthesiologists physical status classification system), medical history, and justification for treatment were collected. Descriptive statistics, including frequencies, percentages and t-tests, were calculated. A total of 298 electronic medical records were reviewed, of which 50 records were excluded due to missing information. Of the 248 electronic medical records included, the average age was 5-years-old and 58% were male. The most common reason for dental treatment under general anesthesia was extent and severity of dental disease (53%), followed by significant medical history (47%) and behavior/pre-cooperative age (39%). Those who were ASA III or IV were older (6.6-years) (p<.001). Common medical comorbidities appear evenly distributed: autism (12%), cardiac anomalies (14%), developmental delay (14%), genetic syndromes/chromosomal disorders (13%), and neurological disorders (12%). Younger age groups (1 to 2 years and 3 to 5 years) had a high percentage of hospitalizations due to the extent and severity of the dental disease (83%) and behavior (77%) (p<0.001). No single comorbidity was seen more often than others in this patient population. The range of medical conditions in this population may be a reflection of the range of pediatric specialty services at Children's Hospital of NewYork-Presbyterian.

A survey on electronic communication in pediatric clinics.

Short message service (SMS) or text messaging is growing in use in personal, business, and more recently healthcare matters. If and how a tool used in adult healthcare may be transitioned to pediatric patients must be carefully studied to minimize potential harms. The current surveys were performed to examine approval for the use of SMS among both parents of pediatric patients as well as pediatric healthcare practitioners. A prospective, paper-based survey was distributed to parents of patients attending pediatric clinics in our large, urban medical center. An online survey was used to poll healthcare providers at all levels who provide care in those same clinics. Overall approval was positive for the use of SMS, with appointment reminders being felt to be the most likely use for the technology by healthcare practitioners. Parental approval was highest when they were able to see the answers their children provided, but parents also approved of the use of SMS when they could not. Among parents and healthcare providers at our large urban pediatric clinics, approval for SMS use was high for a large range of patient ages and clinical uses.

Risk factors (RF) in pediatric stroke differ from those of adults, and they include a wide range of diseases such as heart disease, infections, leukemias, and inborn errors of metabolism. To describe RF for ischemic stroke in a pediatric population, and to examine the relationship of RF with age, sex and type of stroke. An analysis was made of database of 114 children and adolescents with ischemic stroke from January 2003 to July 2012. Risk factors were stratified into 6 categories and ischemic strokes were classified as arterial and venous. We compared the RF with age, sex, and type of stroke (chi2 and OR). The median age was 2.5 years, with 74 (62.2%) males. No RF was identified in 7.9% of patients, and 67% had more than one RF. The most common RF were acute systemic diseases (56.1%), heart disease (35.1%), and chronic systemic diseases (29.8%). There was a statistically significant association between acute systemic disease and age less than 5 years (P<.001), and between chronic systemic disease and age 5 years or more (P<.02). The RF of heart disease was associated with arterial infarction (P<.05), and the acute head and neck disease RF was associated with venous infarction (P<.05). The RF for ischemic stroke are multiple in the pediatric population, and some of them are associated with a specific age and type of stroke. The detection of these factors may help in the primary prevention of people at risk, an early diagnosis, and treatment and prevention of recurrences.

Purpose This study evaluates the relationship between county-level pediatric dentist density and dental care utilization for Medicaid-enrolled children in Washington State. Methods This is a cross-sectional analysis of 604,885 children ages 0-17 enrolled in the Washington State Medicaid Program for ≥11 months in 2012. The relationship between county-level pediatric dentist density, defined as the number of pediatric dentists per 10,000 Medicaid-enrolled children, and preventive dental care utilization was evaluated using linear regression models. Results In 2012, 179 pediatric dentists practiced in 16 of the 39 counties in Washington. County-level pediatric dentist density varied from zero to 5.98 pediatric dentists per 10,000 Medicaid-enrolled children. County-level preventive dental care utilization ranged from 32 percent to 81 percent, with 62 percent of Medicaid-enrolled children in Washington utilizing preventive dental services. After adjusting for confounders, county-level density was significantly associated with county-level dental care utilization (β=1.67, 95 percent CI=0.02, 3.32, p=0.047). Conclusions There is a significant relationship between pediatric dentist density and the proportion of Medicaid-enrolled children who utilize preventive dental care services. Policies aimed at improving pediatric oral health disparities should include strategies to increase the number of oral health care providers, including pediatric dentists, in geographic areas with large proportions of Medicaid-enrolled children.

To study the characteristics and the predictors of survival observed in our pediatric live-donor renal transplant recipients with an allograft that functioned for more than 10 yr. One hundred fifteen children underwent renal transplantation between 1976 and 1995. Of these, 30 had functioning allografts for more than 10 yr (range, 11-18). The patients included 18 males and 12 females, with a mean age at transplantation of 13 yr (range, 5-18). Characteristics of the patients, data on graft survival, and determinants of outcome were obtained by reviewing all medical charts. At most recent follow-up (January 2005), the mean daily dose of azathioprine was 1.2 mg/kg (range, 1-2) and that of prednisone was 0.16 mg/kg (range, 0.1-0.2). Mean creatinine clearance was 72 mL/min per 1.73 m(2) (range, 45-112). Acute rejection occurred in 14 (47%) patients. Seven patients had one episode, five had two episodes, and two had three episodes of acute rejection. Three patients (10%) developed malignancy. A substantial proportion of patients (44%) were short, with a height standard deviation score (SDS) less than -1.88, which is below the third percentile for age and gender. One quarter of the patients, more commonly the females, were obese. Other complications included osteoporosis in 16 (53%) patients, avascular bone necrosis in four (13%), post-transplantation diabetes mellitus in three (10%), and hypertension in 18 (60%). Twelve (40%) patients were married and 27% had children post-transplantation. The independent determinants of long-term graft survival were acute rejection and post-transplant hypertension. Despite good renal function, long-term pediatric renal transplant survivors are at risk of significant morbidity. The determinants of long-term graft survival are acute rejection and post-transplant hypertension.

Asthma is the first cause of children hospitalization and need for emergency and impose high economic burden on the families and governments. We aimed to investigate the economic burden of pediatric asthma and its contribution to family health budget in Iran. Overall, 283 pediatric asthmatic patients, who referred to two tertiary pediatric referral centers in Tehran capital of Iran, included from 2010-2012. Direct and indirect asthma-related costs were recorded during one-year period. Data were statistically analyzed for finding association between the costs and factors that affect this cost (demographic variables, tobacco smoke exposure, control status of asthma and asthma concomitant diseases). Ninety-two (32.5%) females and 191(67.5%) males with the age range of 1-16 yr old were included. We found the annual total pediatrics asthma related costs were 367.97±23.06 USD. The highest cost belonged to the medications (69%) and the lowest one to the emergency (2%). We noticed a significant increasing in boys' total costs ( P =0.011), and 7-11 yr old age group ( P =0.018). In addition, we found significant association between total asthma costs and asthma control status ( P =0.011). The presence of an asthmatic child can consume nearly half of the health budget of a family. Our results emphasis on improving asthma management programs, which leads to successful control status of the disease and reduction in economic burden of pediatric asthma.

Bilateral pediatric cataracts are important cause of visual impairment in children. To study the outcome of bilateral pediatric cataract surgery in young children. Retrospective case series in a tertiary center. Records of pediatric cataracts operated between January 2001 and December 2003, with a minimum follow-up of 3 months, were reviewed retrospectively. Independent sample t-test, Fisher's exact test, and logistic regression using SPSS (Statistical Package for Social Science, Chicago, USA) version 12. 215/257 (83.7%) patients had a minimum follow-up of 3 months. The mean age of presentation to the hospital was 53 months (range: 0-168 months). Congenital cataract was present in 107 patients (58.2%) and developmental cataract in 77 patients (41.8%). The mean age at surgery was 55.2 months (range: 1-168 months). Out of 430 eyes, 269 (62.6%) had an intraocular lens implanted. The mean duration of follow-up was 13.1 months (range: 3-38 months). Pre-operatively, 102 patients (47.3%) had visual acuity <6/60, in the better eye, compared to 37 patients (17.2%) post-operatively ( P < 0.001). Eighty-five patients (39.5%) had visual acuity >6/18. The most common early post-operative complication was fibrinous uveitis in 57 eyes (13.3%) and the most common delayed post-operative complication was posterior capsular opacification in 118 eyes (27.4%). The most important prognostic factor for poor outcome was congenital cataract (odds ratio [OR]: 26.3; 95% confidence interval [CI], 4.4-158.5) and total cataract (OR: 4.8; 95% CI, 1.3-17). Nearly half of the eyes had visual acuity >6/18. The outcome was poorer in congenital cataracts, especially those operated after >1 year of age.

Little prospectively collected data are available comparing the dietary intake of urea cycle disorder (UCD) patients to UCD treatment guidelines or to healthy individuals. To examine the protein and calorie intakes of UCD subjects who participated in clinical trials of glycerol phenylbutyrate (GPB) and compare these data to published UCD dietary guidelines and nutritional surveys. Dietary data were recorded for 45 adult and 49 pediatric UCD subjects in metabolic control during participation in clinical trials of GPB. Protein and calorie intakes were compared to UCD treatment guidelines, average nutrient intakes of a healthy US population based on the National Health and Nutrition Examination Survey (NHANES) and Recommended Daily Allowances (RDA). In adults, mean protein intake was higher than UCD recommendations but lower than RDA and NHANES values, while calorie intake was lower than UCD recommendations, RDA and NHANES. In pediatric subjects, prescribed protein intake was higher than UCD guidelines, similar to RDA, and lower than NHANES data for all age groups, while calorie intake was at the lower end of the recommended UCD range and close to RDA and NHANES data. In pediatric subjects height, weight, and body mass index (BMI) Z-scores were within normal range (- 2 to 2). Pediatric patients treated with phenylbutyrate derivatives exhibited normal height and weight. Protein and calorie intakes in adult and pediatric UCD subjects differed from UCD dietary guidelines, suggesting that these guidelines may need to be reconsidered.

There is a need for a pediatric trauma outcomes benchmarking model that is adapted for Low-and-Middle-Income Countries (LMICs). We used the National-Trauma-Data-Bank (NTDB) and applied constraints specific to resource-poor environments to develop and validate an LMIC-specific pediatric trauma score. We selected a sample of pediatric trauma patients aged 0-14years in the NTDB from 2007 to 2012. Primary outcome was in-hospital death. Logistic regression was used to create the Pediatric Resuscitation and Trauma Outcome (PRESTO) score, which includes only low-tech predictor variables - those easily obtainable at point-of-care. Internal validation was performed using 10-fold cross-validation. External validation compared PRESTO to TRISS using ROC analyses. Among 651,030 patients, there were 64% males. Median age was 7. In-hospital mortality-rate was 1.2%. Mean TRISS predicted mortality was 0.04% (range 0%-43%). Independent predictors included in PRESTO (p<0.01) were age, blood pressure, neurologic status, need for supplemental oxygen, pulse, and oxygen saturation. The sensitivity and specificity of PRESTO were 95.7% and 94.0%. The resulting model had an AUC of 0.98 compared to 0.89 for TRISS. PRESTO satisfies the requirements of low-resource settings and is inherently adapted to children, allowing for benchmarking and eventual quality improvement initiatives. Further research is necessary for in-situ validation using prospectively collected LMIC data. Level III - Case-Control (Prognostic) Study. Copyright © 2017 Elsevier Inc. All rights reserved.

"Holi" is a spring festival celebrated primarily in the Indian subcontinent and also abroad by expatriate Indians. It is a festival of colors, traditionally celebrated by mutual application of colors in different forms on a particular day of the year. These colors frequently comprise a range of synthetic dyes which have harmful effects on the skin and mucosae. Children take part in this colorful festival with much enthusiasm and vigor, making them prone to develop different "Holi"-related dermatoses. Our objective was to find out the different patterns of "Holi"-related dermatoses in a group of pediatric patients. This was a cross-sectional descriptive study carried out over a period of 6 years (2010-2015). Consecutive patients of pediatric age group who attended dermatology outpatient department (OPD) with different dermatoses following application of "Holi" color were included in this study. A total of 63 patients (mean age 11 years; range 1-16 years) were evaluated with a female to male ratio of 1.3:1. Itching is the predominant presenting symptom followed by burning sensation, dryness, scaling, oozing, and loss of hair. Examination revealed that eczematous lesion was the most common (69.8%) reaction pattern followed by xerosis, desquamation, excoriation, erythema, morbilliform eruption, erosion, alopecia, ulceration, acute paronychia, and hyperpigmentation. The face was the most common (76.4%) site of affection. A sizable number of patients of pediatric age group may be affected by "Holi"-related dermatoses necessitating precautionary measures.

It is unknown whether spontaneous gastrorenal shunts actually develop in the pediatric population. The minimum age documented in studies from Asia is 32 (range 32–44) years. This study describes three pediatric patients undergoing balloon-occluded retrograde transvenous obliteration (BRTO) for bleeding gastric varices with two of the three patients undergoing combined partial splenic embolization. The first BRTO is a selective-BRTO via a surgical splenorenal shunt (15 years old) and the other two patients underwent conventional-BRTO via a spontaneous gastrorenal shunt (8 and 14 years old). The recurrent significant bleeding that they exhibited before the combined endovascular therapy did not recur for an averagemore » of 7.1 (range 1.4–14) months. In the second patient, quantitative digitally subtracted angiography was utilized to evaluate the inline portal venous flow before and after BRTO.« less

Legg-Calvé-Perthes disease (LCPD) is an idiopathic hip osteonecrosis prevalent in children < age 15 years. The etiology remains incompletely understood, partly because of multiple potential environmental risk factors and partly because of lack of genetic markers. It has been hypothesized that hyperactivity may induce mechanical stress and/or vascular damage at a fragile joint. To assess children with LCPD for markers of attention deficit hyperactivity disorder (ADHD) relative to their unaffected comparably aged siblings to exclude the contribution of hyperactive behavior versus environmental and/or genetic factors in LCPD. All children followed in the Pediatric Orthopedic Clinic, and their comparably aged siblings, were recruited. ADHD was assessed using the TOVA computerized test and DSM-IV criteria. Quality of life and sleep disorders as ancillary tests were assessed using the Child Health Questionnaire (Parent Form 50), Pediatric Outcomes Data Collection Instrument, and Pediatric Daytime Sleepiness Scale. Sixteen children with LCPD (age 9.1 ± 3.3, 75% males) were compared with their closest-aged siblings (age 9.3 ± 2.6, 30% males). Mean TOVA scores of children with LCPD (-3.79 ± 2.6) and of their non-LCPD siblings (-3.6 ± 4.04) were lower relative to the general population (0 ± 1.8, P < 0.0001). Both group means were in the ADHD range (≤ -1.8) implying that 73% of this LCPD cohort and 53% of their non-LCPD siblings performed in the ADHD range, relative to 3.6% incidence expected in the general population (P < 0.0001). Other test results were similar in both groups. Our findings in a small cohort of children with LCPD and their comparably aged siblings do not support an association between LCPD and ADHD. ADHD markers were equally high in the LCPD children and siblings.

Pediatric head and neck Squamous cell carcinoma (PHNSCC) is a rare disease. The optimum treatment and outcome remains poorly understood because of rarity. We conducted an individual patient data analysis of PHNSCC. Two authors independently searched PubMed, google search, and Cochrane library for eligible studies using following search words: Pediatric Head and neck squamous cell carcinoma, Head and neck squamous cell carcinoma under age of 20, Head and neck squamous cell carcinoma in young, PHNSCC till June 1, 2016 published in English language. Total of 217 patients of PHNSCC were found in the literature. Median age among the cohort was 15 years (Range: 0-20 years) with a clear male preponderance. Oral cavity tumors were commonest 75 (70%) followed by laryngeal neoplasms 16(15%). Median disease free survival was 9 months (Range: 0-216 months). Median overall survival was 48 months (Range: 1-216 months). In univariate analysis treatment modality had significant impact on disease free survival (DFS). Whereas, patients treated with Surgery, Laryngeal primary had significantly better OS. Patients with associated fanconis anemia had significantly worse overall survival (OS). PHNSCC is a rare disease with poorer outcome. Associated DNA defects leads to poorer OS. Patients treated with surgery alone or surgery followed by adjuvant radiation had better DFS and OS. Molecular profiling and personalized therapy may improve survival with limited toxicity. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

AIM: To investigate the evolution of disease phenotype in adult and pediatric onset Crohn’s disease (CD) populations, diagnosed between 1977 and 2008. METHODS: Data of 506 incident CD patients were analyzed (age at diagnosis: 28.5 years, interquartile range: 22-38 years). Both in- and outpatient records were collected prospectively with a complete clinical follow-up and comprehensively reviewed in the population-based Veszprem province database, which included incident patients diagnosed between January 1, 1977 and December 31, 2008 in adult and pediatric onset CD populations. Disease phenotype according to the Montreal classification and long-term disease course was analysed according to the age at onset in time-dependent univariate and multivariate analysis. RESULTS: Among this population-based cohort, seventy-four (12.8%) pediatric-onset CD patients were identified (diagnosed ≤ 17 years of age). There was no significant difference in the distribution of disease behavior between pediatric (B1: 62%, B2: 15%, B3: 23%) and adult-onset CD patients (B1: 56%, B2: 21%, B3: 23%) at diagnosis, or during follow-up. Overall, the probability of developing complicated disease behaviour was 49.7% and 61.3% in the pediatric and 55.1% and 62.4% in the adult onset patients after 5- and 10-years of follow-up. Similarly, time to change in disease behaviour from non stricturing, non penetrating (B1) to complicated, stricturing or penetrating (B2/B3) disease was not significantly different between pediatric and adult onset CD in a Kaplan-Meier analysis. Calendar year of diagnosis (P = 0.04), ileal location (P < 0.001), perianal disease (P < 0.001), smoking (P = 0.038) and need for steroids (P < 0.001) were associated with presence of, or progression to, complicated disease behavior at diagnosis and during follow-up. A change in disease location was observed in 8.9% of patients and it was associated with smoking status (P = 0.01), but not with age at diagnosis. CONCLUSION: Long-term evolution of disease behavior was not different in pediatric- and adult-onset CD patients in this population-based cohort but was associated to location, perianal disease and smoking status.

It is important to understand the anesthetic requirements of elderly patients. However, little is known about age-related recovery from inhalational anesthetics. In this retrospective study, we compared age-related differences in recovery from three inhalational anesthetics  in elderly subjects. Patients were investigated as three age groups which can be defined as age ranges pediatric (< 15 years), adult (15-64 years), and elderly patients ( > 65 years) under general anesthesia using inhalational anesthetics. Anesthesia and surgery times, drug end-tidal concentrations, the time to first movement, time to eye opening, body movement, extubation, and discharge were recorded. The data were analyzed using a Kruskal-Wallis test and Steel-Dwass multiple comparisons. A total of 594 patients were included in the study. In inhalational anesthetics such as sevoflurane, isoflurane, or desflurane, recovery from general anesthesia was not significantly different among age groups (P > 0.05). In inhalational group, recovery was significantly 5-40% faster in desflurane group than in other inhalational anesthetics groups (P < 0.05). There were 20% faster recovery in pediatric and adult groups with desflurane than in elderly with desflurane group. Drug end-tidal inhalational concentrations in pediatric group were significantly higher than that in adult and elderly groups of all inhalational anesthetics, respectively (P < 0.05). In the current study, we have found that recovery from desflurane was faster in younger patients than in other inhalational anesthetics and aged patients.

The goal of this retrospective cohort study of pediatric patients exposed to flumazenil was to identify the frequency of seizures. Included patient were those aged 12 years or younger who received flumazenil, who had evidence of clinical poisoning as defined by an altered mental status, and who were reported to the California Poison Control System for the period 1999 to 2008. Data variables were age, sex, seizure, death, acute exposure to a benzodiazepine, drugs of exposure, long-term use of benzodiazepines, history of a seizure disorder, mental status before flumazenil administration, and poison center recommendation of flumazenil (yes/no). Eighty-three patients were included. Forty-eight (58%) of this subset were female. Median age was 2 years (range, 3 months-12 years). Seventy (84%) patients were younger than 5 years. Of the 83 patients, 68 (82%) were allegedly exposed to a benzodiazepine; whereas, 12 (15%) had been allegedly exposed to a proconvulsant drug. No flumazenil-related seizures occurred (0% with 95% confidence interval, 0%-4%). The California Poison Control System recommended flumazenil use in 60 (72%) of the 83 cases, and 48 of these had been allegedly exposed to a benzodiazepine. No flumazenil-associated seizures occurred among allegedly benzodiazepine- and non-benzodiazepine-poisoned pediatric patients aged 12 years or younger.

The study aimed to test the hypothesis that computer-based calculation of malnutrition risk may enhance the ability to identify pediatric patients at malnutrition-related risk for an unfavorable outcome. The Pediatric Digital Scaled MAlnutrition Risk screening Tool (PeDiSMART), incorporating the World Health Organization (WHO) growth reference data and malnutrition-related parameters, was used. This was a prospective cohort study of 500 pediatric patients aged 1 month to 17 years. Upon admission, the PeDiSMART score was calculated and anthropometry was performed. Pediatric Yorkhill Malnutrition Score (PYMS), Screening Tool Risk on Nutritional Status and Growth (STRONGkids), and Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP) malnutrition screening tools were also applied. PeDiSMART's association with the clinical outcome measures (weight loss/nutrition support and hospitalization duration) was assessed and compared with the other screening tools. The PeDiSMART score was inversely correlated with anthropometry and bioelectrical impedance phase angle (BIA PhA). The score's grading scale was based on BIA Pha quartiles. Weight loss/nutrition support during hospitalization was significantly independently associated with the malnutrition risk group allocation on admission, after controlling for anthropometric parameters and age. Receiver operating characteristic curve analysis showed a sensitivity of 87% and a specificity of 75% and a significant area under the curve, which differed significantly from that of STRONGkids and STAMP. In the subgroups of patients with PeDiSMART-based risk allocation different from that based on the other tools, PeDiSMART allocation was more closely related to outcome measures. PeDiSMART, applicable to the full age range of patients hospitalized in pediatric departments, graded according to BIA PhA, and embeddable in medical electronic records, enhances efficacy and reproducibility in identifying pediatric patients at malnutrition-related risk for an unfavorable outcome. Patient allocation according to the PeDiSMART score on admission is associated with clinical outcome measures. © 2014 American Society for Parenteral and Enteral Nutrition.

OBJECTIVE Cerebral mapping for surgical planning and operative guidance is a challenging task in neurosurgery. Pediatric patients are often poor candidates for many modern mapping techniques because of inability to cooperate due to their immature age, cognitive deficits, or other factors. Resting-state functional MRI (rs-fMRI) is uniquely suited to benefit pediatric patients because it is inherently noninvasive and does not require task performance or significant cooperation. Recent advances in the field have made mapping cerebral networks possible on an individual basis for use in clinical decision making. The authors present their initial experience translating rs-fMRI into clinical practice for surgical planning in pediatric patients. METHODS The authors retrospectively reviewed cases in which the rs-fMRI analysis technique was used prior to craniotomy in pediatric patients undergoing surgery in their institution. Resting-state analysis was performed using a previously trained machine-learning algorithm for identification of resting-state networks on an individual basis. Network maps were uploaded to the clinical imaging and surgical navigation systems. Patient demographic and clinical characteristics, including need for sedation during imaging and use of task-based fMRI, were also recorded. RESULTS Twenty patients underwent rs-fMRI prior to craniotomy between December 2013 and June 2016. Their ages ranged from 1.9 to 18.4 years, and 12 were male. Five of the 20 patients also underwent task-based fMRI and one underwent awake craniotomy. Six patients required sedation to tolerate MRI acquisition, including resting-state sequences. Exemplar cases are presented including anatomical and resting-state functional imaging. CONCLUSIONS Resting-state fMRI is a rapidly advancing field of study allowing for whole brain analysis by a noninvasive modality. It is applicable to a wide range of patients and effective even under general anesthesia. The nature of resting-state analysis precludes any need for task cooperation. These features make rs-fMRI an ideal technology for cerebral mapping in pediatric neurosurgical patients. This review of the use of rs-fMRI mapping in an initial pediatric case series demonstrates the feasibility of utilizing this technique in pediatric neurosurgical patients. The preliminary experience presented here is a first step in translating this technique to a broader clinical practice.

The aim of this study was to investigate the validity of office spirometry in primary care pediatric practices. Ten primary care pediatricians undertook a spirometry training program that was led by 2 pediatric pulmonologists from the Pediatric Department of the University of Padova. After the pediatricians' training, children with asthma or persistent cough underwent a spirometric test in the pediatrician's office and at a pulmonary function (PF) laboratory, in the same day in random order. Both spirometric tests were performed with a portable turbine flow sensor spirometer. We assessed the quality of the spirometric tests and compared a range of PF parameters obtained in the pediatricians' offices and in the PF laboratory according to the Bland and Altman method. A total of 109 children (mean age: 10.4 years; range: 6-15) were included in the study. Eighty-five (78%) of the spirometric tests that were performed in the pediatricians' offices met all of the acceptability and reproducibility criteria. The 24 unacceptable test results were attributable largely to a slow start and failure to satisfy end-of-test criteria. Only the 85 acceptable spirometric tests were considered for analysis. The agreement between the spirometric tests that were performed in the pediatrician's office and in the PF laboratory was good for the key parameters (forced vital capacity, forced expiratory volume in 1 second, and forced expiratory flow between 25% and 75%). The repeatability coefficient was 0.26 L for forced expiratory volume in 1 second (83 of 85 values fall within this range), 0.30 L for forced vital capacity (81 values fall within this range), and 0.58 L/s for forced expiratory flow between 25% and 75% (82 values fall within this range). In 79% of cases, the primary care pediatricians interpreted the spirometric tests correctly. It seems justifiable to perform spirometry in pediatric primary care, but an integrated approach involving both the primary care pediatrician and certified pediatric respiratory medicine centers is recommended because effective training and quality assurance are vital prerequisites for successful spirometry.

To compare outcomes and charges of health care delivery to extremely low-birth-weight infants by neonatal nurse practitioners (NNP) and pediatric residents. Retrospective cohort study. A 56-bed neonatal intensive care unit (NICU) in a university teaching hospital. Study population included all infants with birth weights less than 1000 g who were admitted to the NICU during the 2-year period between September 1, 1994, and August 31, 1996. Infants who died earlier than 12 hours of age, or who were admitted after 1 week of age or with major malformations, chromosomal abnormalities, or congenital infections were excluded. There were separate teams of NNPs and residents providing care around the clock. The study group included 201 infants with birth weights of less than 1000 g. The NNP team cared for 94 infants and the resident team cared for 107 infants. Survival, length of stay, and total charges. Survival to discharge occurred for 71 NNP team infants (76%) and 82 resident team infants (77%) (P =.87). The median total length of stay was 87 days (range, 39-230 days) for NNP team infants and 88 days (range, 41-365 days) for resident team infants (P =.54). There were no significant differences between NNP infants and resident team infants in the prevalence of severe intracranial hemorrhage, threshold retinopathy of prematurity, or chronic lung disease at 36 weeks postconceptual age. Median total NICU hospital charges were $141,624 (range, $52,020-$693,018) for NNP team infants and $139,388 (range, $50,178-$990,865) for resident team infants (P =.89). There were no significant differences between NNP team infants and resident team infants in NICU charges for laboratory, radiology, or pharmacy services. Neonatal nurse practitioners and pediatric residents provided comparable patient care to extremely low-birth-weight infants, with similar outcomes and similar charges.

Although the exact incidence of pediatric oral lichen planus (OLP) is unknown, the oral mucosa seems to be less commonly involved, and the clinical presentation is often atypical. The aim of the study is to present a case series of OLP in childhood. From our database, we retrospectively selected and analyzed the clinical data of OLP patients under the age of 18 where the diagnosis had been confirmed by histopathological analysis. The case series from our database shows eight patients, four males and four females. The mean (±SD) age at the time of diagnosis of the disease was 13.5 (±2.73) years, ranging in age from 9 to 17. Clinically, a reticular pattern was present in six patients (75%), and the tongue was the most commonly involved oral site (six cases, 75%). We also report the first case of OLP in a 9-year-old girl affected by autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy. We report the largest case series of pediatric OLP published in literature thus far. Differences in the disease between adults and pediatric patients have been detected, but further investigation and a larger case series are needed to establish any detailed differences in clinical outcomes. © 2017 The International Society of Dermatology.

Autoimmune hepatitis (AIH) is a progressive inflammatory liver disease of unknown etiology, with limited population-based estimates of pediatric incidence. We reported the incidence of pediatric AIH in Canada and described its clinical characteristics. We conducted a retrospective cohort study of patients aged <18 years diagnosed with AIH between 2000-2009 at all pediatric centers in Canada. A total of 159 children with AIH (60.3% female, 13.2% type 2 AIH) were identified. Annual incidence was 0.23 per 100000 children. Median age at presentation for type 1 was 12 years (interquartile range: 11-14) versus 10 years for type 2 (interquartile range: 4.5-13) (P = .03). Fatigue (58%), jaundice (54%), and abdominal pain (49%) were the most common presenting symptoms. Serum albumin (33 vs 38 g/L; P = .03) and platelet count (187 000 vs 249 000; P <.001) were significantly lower and the international normalized ratio (1.4 vs 1.2; P <.001) was higher in cirrhotic versus noncirrhotic patients. Initial treatment included corticosteroids (80%), azathioprine (32%), and/or cyclosporine (13%). Response to treatment at 1 year was complete in 90%, and partial in 3%. 3% of patients had no response, and 3% responded and later relapsed. Nine patients underwent liver transplantation, and 4 patients died at a mean follow-up of 4 years. AIH is uncommon in children and adolescents in Canada. Type 1 AIH was diagnosed 5.5 times more frequently than type 2 AIH. Most patients respond well to conventional therapy, diminishing the need for liver transplantation.

Alterations in the gut microbial community composition may be influential in neurological disease. Microbial community profiles were compared between early onset pediatric multiple sclerosis (MS) and control children similar for age and sex. Children ≤18 years old within 2 years of MS onset or controls without autoimmune disorders attending a University of California, San Francisco, USA, pediatric clinic were examined for fecal bacterial community composition and predicted function by 16S ribosomal RNA sequencing and phylogenetic reconstruction of unobserved states (PICRUSt) analysis. Associations between subject characteristics and the microbiota, including beta diversity and taxa abundance, were identified using non-parametric tests, permutational multivariate analysis of variance and negative binomial regression. Eighteen relapsing-remitting MS cases and 17 controls (mean age 13 years; range 4-18) were studied. Cases had a short disease duration (mean 11 months; range 2-24) and half were immunomodulatory drug (IMD) naïve. Whilst overall gut bacterial beta diversity was not significantly related to MS status, IMD exposure was (Canberra, P < 0.02). However, relative to controls, MS cases had a significant enrichment in relative abundance for members of the Desulfovibrionaceae (Bilophila, Desulfovibrio and Christensenellaceae) and depletion in Lachnospiraceae and Ruminococcaceae (all P and q < 0.000005). Microbial genes predicted as enriched in MS versus controls included those involved in glutathione metabolism (Mann-Whitney, P = 0.017), findings that were consistent regardless of IMD exposure. In recent onset pediatric MS, perturbations in the gut microbiome composition were observed, in parallel with predicted enrichment of metabolic pathways associated with neurodegeneration. Findings were suggestive of a pro-inflammatory milieu. © 2016 EAN.

To review the demographics and workload characteristics of pediatric neurology in Canada. A standardized survey questionnaire was mailed out to practicing pediatric neurologists in Canada in 2001. Variables examined were age, gender, hours on call, regular hours worked per week, type of practice and projected changes in practice over next five to ten years. Results were compared to the 1994 Pediatric Neurology Manpower Survey which had used the same survey instrument. Fifty-six (70%) pediatric neurologists practicing in Canada returned the survey. As was the case in 1994, no significant differences in workload were found based on age or gender. The average age of the practicing pediatric neurologist in 2001 was 51 years compared to 45 years in 1994. The proportion of physicians over 55 years in 2001 was 35% compared to 25% in 1994.

Lorazepam is one of the preferred agents used for intravenous treatment of status epilepticus (SE). We combined data from two pediatric clinical trials to characterize the population pharmacokinetics of intravenous lorazepam in infants and children aged 3 months to 17 years with active SE or a history of SE. We developed a population pharmacokinetic model for lorazepam using the NONMEM software. We then assessed exploratory exposure-response relationships using the overall efficacy and safety study endpoints, and performed dosing simulations. A total of 145 patients contributed 439 pharmacokinetic samples. The median (range) age and dose were 5.4 years (0.3-17.8) and 0.10 mg/kg (0.02-0.18), respectively. A two-compartment pharmacokinetic model with allometric scaling described the data well. In addition to total body weight (WT), younger age was associated with slightly higher weight-normalized clearance (CL). The following relationships characterized the typical values for the central compartment volume (V1), CL, peripheral compartment volume (V2), and intercompartmental CL (Q), using individual subject WT (kg) and age (years): V1 (L) = 0.879*WT; CL (L/h) = 0.115*(Age/4.7) 0.133 *WT 0.75 ; V2 (L) = 0.542*V1; Q (L/h) = 1.45*WT 0.75 . No pharmacokinetic parameters were associated with clinical outcomes. Simulations suggest uniform pediatric dosing (0.1 mg/kg, to a maximum of 4 mg) can be used to achieve concentrations of 50-100 ng/mL in children with SE, which have been previously associated with effective seizure control. The population pharmacokinetics of lorazepam were successfully described using a sparse sampling approach and a two-compartment model in pediatric patients with active SE.

Children often present to the pediatric emergency department (ED) with a reported penicillin allergy. The true incidence of pediatric penicillin allergy is low, and patients may be inappropriately denied first-line antibiotics. We hypothesized that more than 70% of reported penicillin allergies in the pediatric ED are low risk for true allergy. Parents of children presenting to the pediatric ED with parent-reported penicillin allergy completed an allergy questionnaire. The questionnaire included age at allergy diagnosis, symptoms of allergy, and time to allergic reaction from first dose. The allergy symptoms were dichotomized into high and low risk in consultation with a pediatric allergist before questionnaire implementation. A total of 605 parents were approached; 500 (82.6%) completed the survey. The median (interquartile range) age of the children at diagnosis was 1 year (7 months, 2 years); 75% were diagnosed before their third birthday. Overall, 380 (76%) (95% confidence interval 72.3, 79.7) children had exclusively low-risk symptoms. The most commonly reported symptoms were rash (466, 92.8%) and itching (203, 40.6%). Of the 120 children with one or more high-risk symptom, facial swelling (50, 10%) was the most common. Overall, 354 children (71%) were diagnosed after their first exposure to penicillin. Symptom onset within 24 hours of medication administration occurred in 274 children (54.8%). Seventy-six percent of patients with parent-reported penicillin allergy have symptoms unlikely to be consistent with true allergy. Determination of true penicillin allergy in patients with low-risk symptoms may permit the increased use of first-line penicillin antibiotics. Copyright © 2016 Academic Pediatric Association.

Age Limit of Pediatrics.

PubMed

Hardin, Amy Peykoff; Hackell, Jesse M

2017-09-01

Pediatrics is a multifaceted specialty that encompasses children's physical, psychosocial, developmental, and mental health. Pediatric care may begin periconceptionally and continues through gestation, infancy, childhood, adolescence, and young adulthood. Although adolescence and young adulthood are recognizable phases of life, an upper age limit is not easily demarcated and varies depending on the individual patient. The establishment of arbitrary age limits on pediatric care by health care providers should be discouraged. The decision to continue care with a pediatrician or pediatric medical or surgical subspecialist should be made solely by the patient (and family, when appropriate) and the physician and must take into account the physical and psychosocial needs of the patient and the abilities of the pediatric provider to meet these needs.

Treatment of pediatric patients and young adults with particle therapy at the Heidelberg Ion Therapy Center (HIT): establishment of workflow and initial clinical data

PubMed Central

2012-01-01

Background To report on establishment of workflow and clinical results of particle therapy at the Heidelberg Ion Therapy Center. Materials and methods We treated 36 pediatric patients (aged 21 or younger) with particle therapy at HIT. Median age was 12 years (range 2-21 years), five patients (14%) were younger than 5 years of age. Indications included pilocytic astrocytoma, parameningeal and orbital rhabdomyosarcoma, skull base and cervical chordoma, osteosarcoma and adenoid-cystic carcinoma (ACC), as well as one patient with an angiofibroma of the nasopharynx. For the treatment of small children, an anesthesia unit at HIT was established in cooperation with the Department of Anesthesiology. Results Treatment concepts depended on tumor type, staging, age of the patient, as well as availability of specific study protocols. In all patients, particle radiotherapy was well tolerated and no interruptions due to toxicity had to be undertaken. During follow-up, only mild toxicites were observed. Only one patient died of tumor progression: Carbon ion radiotherapy was performed as an individual treatment approach in a child with a skull base recurrence of the previously irradiated rhabdomyosarcoma. Besides this patient, tumor recurrence was observed in two additional patients. Conclusion Clinical protocols have been generated to evaluate the real potential of particle therapy, also with respect to carbon ions in distinct pediatric patient populations. The strong cooperation between the pediatric department and the department of radiation oncology enable an interdisciplinary treatment and stream-lined workflow and acceptance of the treatment for the patients and their parents.

The purpose of this study was to compare the technical success and complication rates of ultrasonography-guided central venous catheterization between adult and pediatric patients which have not been reported previously. In a 4-year period, 859 ultrasonography-guided central vein catheterizations in 688 adult patients and 247 catheterizations in 156 pediatric patients were retrospectively evaluated. Mean age was 56.3 years (range, 18 to 95 years) for adults and 3.3 years (range, 0.1 to 16.3 years) for children. The preferred catheterization site was internal jugular vein in 97% of adults and 85% of children. The technical success rate, mean number of punctures, andmore » rate of single wall puncture were 99.4%, 1.04 (range, 1-3), and 83% for adults and 90.3%, 1.25 (range, 1-5), and 49% for children, respectively. All the differences were statistically significant (p < 0.05). Complication rates were 2.3% and 2.4% for adults and children, respectively (p > 0.05). Major complications such as pneumothorax and hemothorax were not seen in any group. In conclusion, ultrasonography-guided central venous catheterization has a high technical success rate, lower puncture attempt rate, and higher single wall puncture rate in adults compared to children. Complication rates are comparable in the two groups.« less

Acute severe hypertension occurs infrequently in pediatric patients and, consequently, data on the efficacy and safety of most antihypertensive agents, as well as the adverse events associated with these agents, are very limited in this population. In this case series, we evaluated the use of metoprolol infusion in children with hypertensive emergencies. The study population comprised children younger than 18 years who had been admitted to the pediatric intensive care unit at King Abdullah University Hospital with blood pressure above the 99th percentile for age, height, and sex and who were symptomatic at the time of presentation. Metoprolol was given as an infusion at a dose of 1-5 mcg/kg/min. The rate of decrease in blood pressure, side effects from the medication, and outcome were assessed. Thirteen patients ranging in age from 2 months to 16 years were included in this study. The initial mean blood pressure was 23-75 mmHg above the 99th percentile for age, height, and sex. Metoprolol was initiated at a dose of 0.5 mcg/kg/min and titrated according to the target blood pressure to a maximum of 5 mcg/kg/min. Mean blood pressure fell by an average of 12.3, 20.4, and 27.1% at 1, 8, and 24 h, respectively, which is consistent with findings on the use of other intravenous medications reported in published studies. The heart rate did not decrease below the normal range for age. There were no significant side effects of the metoprolol infusion. All patients were discharged home with no neurological sequelae secondary to their hypertension. An infusion of metoprolol for a hypertensive emergency is a safe and effective treatment for pediatric patients.

Little is known about long-term quality of life (QoL) of survivors of pediatric differentiated thyroid carcinoma. Therefore, this study aimed to evaluate generic health-related QoL (HRQoL), fatigue, anxiety, and depression in these survivors compared with matched controls, and to evaluate thyroid cancer-specific HRQoL in survivors only. Survivors diagnosed between 1970 and 2013 at age ≤18 years, were included. Exclusion criteria were a follow-up <5 years, attained age <18 years, or diagnosis of DTC as a second malignant neoplasm (SMN). Controls were matched by age, sex, and socioeconomic status. Survivors and controls were asked to complete 3 questionnaires [Short-Form 36 (HRQoL), Multidimensional Fatigue Inventory 20 (fatigue), and Hospital Anxiety and Depression Scale (anxiety/depression)]. Survivors completed a thyroid cancer-specific HRQoL questionnaire. Sixty-seven survivors and 56 controls. Median age of survivors at evaluation was 34.2 years (range, 18.8 to 61.7). Median follow-up was 17.8 years (range, 5.0 to 44.7). On most QoL subscales, scores of survivors and controls did not differ significantly. However, survivors had more physical problems (P = 0.031), role limitations due to physical problems (P = 0.021), and mental fatigue (P = 0.016) than controls. Some thyroid cancer-specific complaints (e.g., sensory complaints and chilliness) were present in survivors. Unemployment and more extensive disease or treatment characteristics were most frequently associated with worse QoL. Overall, long-term QoL in survivors of pediatric DTC was normal. Survivors experienced mild impairment of QoL in some domains (physical problems, mental fatigue, and various thyroid cancer-specific complaints). Factors possibly affecting QoL need further exploration. Copyright © 2017 Endocrine Society

To assess the part-time workforce and average hours worked per week among pediatric subspecialists in the 15 medical subspecialties certified by the American Board of Pediatrics. We examined data from pediatric subspecialists who enrolled in Maintenance of Certification with the American Board of Pediatrics from 2009 to 2015. Data were collected via an online survey. Providers indicated whether they worked full time or part time and estimated the average number of hours worked per week in clinical, research, education, and administrative tasks, excluding time on call. We calculated and compared the range of hours worked by those in full- and part-time positions overall, by demographic characteristics, and by subspecialty. Overall, 9.6% of subspecialists worked part time. There was significant variation in part-time employment rates between subspecialties, ranging from 3.8% among critical care pediatricians to 22.9% among developmental-behavioral pediatricians. Women, American medical graduates, and physicians older than 70 years of age reported higher rates of part-time employment than men, international medical graduates, and younger physicians. There was marked variation in the number of hours worked across subspecialties. Most, but not all, full-time subspecialists reported working at least 40 hours per week. More than one-half of physicians working part time in hematology and oncology, pulmonology, and transplant hepatology reported working at least 40 hours per week. There are unique patterns of part-time employment and hours worked per week among pediatric medical subspecialists that make simple head counts inadequate to determine the effective workforce. Our findings are limited to the 15 American Board of Pediatrics-certified medical subspecialties. Copyright © 2017 Elsevier Inc. All rights reserved.

2011-01-01

The objective of the present study was to quantify ossification processes of the human pediatric cervical spine. Computed tomography images were obtained from a high resolution scanner according to clinical protocols. Bone window images were used to identify the presence of the primary synchondroses of the atlas, axis, and C3 vertebrae in 101 children. Principles of logistic regression were used to determine probability distributions as a function of subject age for each synchondrosis for each vertebra. The mean and 95% upper and 95% lower confidence intervals are given for each dataset delineating probability curves. Posterior ossifications preceded bilateral anterior closures of the synchondroses in all vertebrae. However, ossifications occurred at different ages. Logistic regression results for closures of different synchondrosis indicated p-values of <0.001 for the atlas, ranging from 0.002 to <0.001 for the axis, and 0.021 to 0.005 for the C3 vertebra. Fifty percent probability of three, two, and one synchondroses occurred at 2.53, 6.97, and 7.57 years of age for the atlas; 3.59, 4.74, and 5.7 years of age for the axis; and 1.28, 2.22, and 3.17 years of age for the third cervical vertebrae, respectively. Ossifications occurring at different ages indicate non-uniform maturations of bone growth/strength. They provide an anatomical rationale to reexamine dummies, scaling processes, and injury metrics for improved understanding of pediatric neck injuries PMID:22105393

Too many pediatric trampoline injuries.

Furnival, R A; Street, K A; Schunk, J E

1999-05-01

Recent reports note a dramatic increase in the number of pediatric trampoline injuries (PTI) during the past several years. In 1996, the US Consumer Product Safety Commission estimates that 83 000 patients received treatment for trampoline injuries in US hospital emergency departments (EDs), and that approximately 75% of these patients were <15 years of age. We sought to review our experience with PTI since our previous report (Pediatrics 1992;89:849), and to determine if the American Academy of Pediatrics' current (Pediatrics 1981;67:438) safety recommendations are adequate. Retrospective medical record review of all PTI patients presenting to the pediatric ED from November 1990 through November 1997. A total of 727 PTI patients were included; medical records were unavailable for 3 patients. The annual number of PTI nearly tripled during the study period, from 51 in 1991 to a peak of 148 in 1996. PTI patients were 53% female, with a median age of 7 years; 37% were <6 years of age. Privately owned trampolines accounted for 99% of PTI. Most injuries (66%) occurred on the trampoline, 28% resulted from falls off, and 4% from imaginative mechanisms. One hundred eleven patients (15%) suffered severe injury (1990 Abbreviated Injury Scale value >/=3), usually of an extremity (89 out of 111). Fractures occurred in 324 patients (45%). Spinal injuries were common (12%), including 7 patients with cervical or thoracic fractures, and 1 with C7 paraplegia. Fractures were more frequently associated with falls off the trampoline, whereas spinal injuries more frequently occurred on the trampoline. Eighty patients (11%) required prehospital medical transport to our ED, 584 (80%) had ED radiographs, and 382 (53%) required pediatric surgical subspecialty involvement. Seventeen percent of PTI patients (125 out of 727) were admitted to the hospital, including 9 to the pediatric intensive care unit; 99 (14%) required one or more operations. Mean hospital stay was 2 days (range, 1-63 days); 24 stays (19%) were for >/=3 days. We estimate that the hospital charges for the acute medical care of PTI study patients at our institution totaled approximately $700 000. PTI are dramatically increasing in number, and result in considerable childhood morbidity. Most PTI occur on privately owned trampolines. Few, if any, safety recommendations for the trampoline are followed. We support recommendations for a ban on the recreational, school, and competitive pediatric use of trampolines.

There is no consensus regarding the appropriate use of endoscopic retrograde cholangiopancreatography (ERCP) in pediatric trauma. We report our experience with ERCP for management of pediatric pancreatic and biliary injury following blunt abdominal trauma. A retrospective chart review was performed for pediatric patients with blunt abdominal trauma from July 2008 through December 2012 at our pediatric trauma center. For patients who underwent ERCP, demographics, injury characteristics, diagnostic details, procedures performed, length of stay, total parenteral nutrition use, and complications were reviewed. There were 532 patients identified: 115 hepatic injuries, 25 pancreatic injuries and one gall bladder injury. Nine patients (mean age 7.8 years) underwent ERCP. Seven (78%) had pancreatic injuries, while two (22%) had bilateral hepatic duct injuries. The median time to diagnosis was one day (range, 0-12). Diagnostic ERCP only was performed in three patients, two of which proceeded to distal pancreatectomy. Five patients had stents placed (two biliary and three pancreatic) and four sphincterotomies were performed. Despite pancreatic stenting, one patient required distal pancreatectomy for persistent leak. Median length of stay was 11 days. Pediatric pancreatic and biliary ductal injuries following blunt abdominal trauma are uncommon. ERCP can safely provide definitive treatment for some patients. Copyright © 2015 Elsevier Inc.

2014-01-01

A summary of the evidence pertaining to the association between methylenetetrahydrofolate reductase (MTHFR) C677T and overall survival in pediatric acute lymphoblastic leukemia (ALL) is not currently available. We thus reviewed the literature on the association between MTFHR C677T and overall survival in pediatric ALL. We searched PubMed/MEDLINE, Scopus and ISI Web of Knowledge literature databases without language restrictions to identify observational studies among children diagnosed between ages 0 and 19 years that assessed MTHFR 677 polymorphisms in relation to ALL survival. We identified six studies comprising 909 pediatric patients with ALL. The magnitude of relative risk (RR) for pediatric ALL mortality varied by genotype comparison and study population, ranging from RR = 0.84 (95% confidence limits [CL]: 0.24, 3.0) for a TT vs. CT/CC comparison to RR = 7.0 (95% CL: 0.98, 49) for a TT vs. CC comparison. The current evidence suggests that individuals with MTHFR 677 variants (i.e. at least one T allele) may have a higher relative risk of pediatric ALL mortality, with greater statistical support for MTHFR 677TT. With more detailed supporting evidence, MTHFR 677 genotyping at diagnosis could provide an option for individualizing therapy and further reducing pediatric ALL mortality in certain populations.

Both our teams were the first to implement pediatric robotic surgery in France. The aim of this study was to define the key points we brought to light so other pediatric teams that want to set up a robotic surgery program will benefit. We reviewed the medical records of all children who underwent robotic surgery between Nov 2007 and June 2011 in both departments, including patient data, installation and changes, operative time, hospital stay, intraoperative complications, and postoperative outcome. The department's internal organization, the organization within the hospital complex, and cost were evaluated. A total of 96 procedures were evaluated. There were 38 girls and 56 boys with average age at surgery of 7.6 years (range, 0.7-18 years) and average weight of 26 kg (range, 6-77 kg). Thirty-six patients had general surgery, 57 patients urologic surgery, and 1 thoracic surgery. Overall average operative time was 189 min (range, 70-550 min), and average hospital stay was 6.4 days (range, 2-24 days). The procedures of 3 patients were converted. Median follow-up was 18 months (range, 0.5-43 months). Robotic surgical procedure had an extra cost of 1934 compared to conventional open surgery. Our experience was similar to the findings described in the literature for feasibility, security, and patient outcomes; we had an overall operative success rate of 97 %. Three main actors are concerned in the implementation of a robotic pediatric surgery program: surgeons and anesthetists, nurses, and the administration. The surgeon is at the starting point with motivation for minimally invasive surgery without laparoscopic constraints. We found that it was possible to implement a long-lasting robotic surgery program with comparable quality of care.

Ketamine is an emerging therapy for pediatric refractory status epilepticus. The circumstances of its use, however, are understudied. The authors described pediatric refractory status epilepticus treated with ketamine from 2010 to 2014 at 45 centers using the Pediatric Hospital Inpatient System database. For comparison, they described children treated with pentobarbital. The authors estimated that 48 children received ketamine and pentobarbital for refractory status epilepticus, and 630 pentobarbital without ketamine. Those receiving only pentobarbital were median age 3 [interquartile range 0-10], and spent 30 [18-52] days in-hospital, including 17 [9-28] intensive care unit (ICU) days; 17% died. Median cost was $148 000 [81 000-241 000]. The pentobarbital-ketamine group was older (7 [2-11]) with longer hospital stays (51 [30-93]) and more ICU days (29 [20-56]); 29% died. Median cost was $298 000 [176 000-607 000]. For 71%, ketamine was given ≥1 day after pentobarbital. Ketamine cases per half-year increased from 2 to 9 ( P < .05). Ketamine is increasingly used for severe pediatric refractory status epilepticus, typically after pentobarbital. Research on its effectiveness is indicated.

Pediatric patients with acute lymphoblastic leukemia (ALL) are treated with oral 6-mercaptopurine (6MP) for nearly 2 years, but no pediatric formulation has been available. In this study, an oral 6MP liquid suitable for pediatric use was developed and tested in the target population. A randomized cross-over study was performed in 20 pediatric ALL patients (age 1.9 - 14.6 years), comparing pharmacokinetics and pharmacodynamics of a newly developed 6MP liquid formulation to 6MP capsules, both taken orally for 4 weeks. Based upon trough levels of the principal active metabolite,6-thioguanine nucleotides (6-TGN),a relative bioavailability of the liquid vs. capsules of 1.01 was found (90% CI 0.86 - 1.20), demonstrating bioequivalence. This was supported by the similarly observed 6MP dosages needed for leucocyte depletion, for both formulations (35 mg/day (range 10 - 115 mg)). 75% of the parents/patients (p = 0.005) preferred the oral liquid over the capsules because of the ease of administration. We conclude that the novel 6MP liquid is a promising treatment for ALL.

The aim of this study was to identify the different influencing patterns of demographic and epilepsy-related variables on various aspects of psychosocial function in pediatric epilepsy. Five hundred ninety-eight patients with pediatric epilepsy between the ages of 4 and 18 years (boys=360, 60% and girls=238, 40%) and their parents participated in the study. Parents completed the Social Maturity Scale (SMS), the Korean version of the Child Behavior Checklist (K-CBCL), and the Korean version of the Quality of Life in Childhood Epilepsy Questionnaire (K-QOLCE) to assess daily living function, behavior, and quality of life. The Children's Global Assessment Scale (CGAS) was completed by clinicians to assess general adaptive function. Demographic variables, such as age and sex of child, and epilepsy-related clinical variables, including seizure type, seizure frequency, duration of epilepsy, and number of medications, were obtained from medical records. Demographic and epilepsy-related clinical variables had a strong influence (22-32%) on the cognition-related domain such as general adaptive function, school/total competence, and quality of life for cognitive function while a comparatively smaller effect (2-16%) on the more psychological domain including behavioral, emotional, and social variables. Younger age, shorter duration of illness, and smaller number of medications showed a strong positive impact on psychosocial function in pediatric epilepsy, particularly for adaptive function, competence, and quality-of-life aspects. Given the wide range of impact of demographic and clinical variables on various facets of psychosocial functions, more specific understanding of the various aspects of factors and their particular pattern of influence may enable more effective therapeutic approaches that address both the medical and psychological needs in pediatric epilepsy.

Malnutrition is common in infants and children with congenital heart disease (CHD). Cardiac surgery has improved patient survival and nutritional status. To evaluate the impact of cardiac surgery on nutritional status of pediatric patients with CHD. A prospective cohort study was conducted in pediatric patients with CHD, admitted for cardiac surgery at Queen Sirikit National Institute of Child Health (QSNICH), Bangkok, from August 1st, 2002 to 2003. Demographic data, cardiac and related problems were obtained before operation. Anthropometry was performed at the presentation and post cardiac surgery. Nutritional status was assessed by Z-score of weight for age (ZWA), weight for height (ZWH) and height for age (ZHA). Malnutrition was defined as Z-score <- 2 and compared pre- and post-operation using Chi-square. Paired t-test was used to compare mean Z-score and p-value < 0.05 was statistically significant. All of 161 pediatric patients with CHD undergoing cardiac surgery were 41% males and 59% females. Patients' age ranged from 1 month to 15 years. The related problems included low birth weight (28%) and feeding problem (58%). The most common CHD was ventricular septal defect (29%). The nutritional status of the patients before surgery was defined as normal 57%, malnutrition 40% and over-nutrition 3%. Malnutrition included underweight 28%, wasting 22% and stunting 16%. Post cardiac surgery, the means of ZWA, ZWH and ZHA were significantly increased and the prevalence of underweight and wasting were decreased to 17% and 6% respectively, with statistically significant from the baseline (p < 0.05). Malnutrition was found in 40% of pediatric patients with CHD and cardiac surgery has a significant positive effect on weight gain and nutritional status.

Pediatric acute gastroenteritis: understanding caregivers' experiences and information needs.

2017-05-01

Pediatric acute gastroenteritis (AGE) is a common condition with high health care utilization, persistent practice variation, and substantial family burden. An initial approach to resolve these issues is to understand the patient/caregiver experience of this illness. The objective of this study was to describe caregivers' experiences of pediatric AGE and identify their information needs, preferences, and priorities. A qualitative, descriptive study was conducted. Caregivers of a child with AGE were recruited for this study in the pediatric emergency department (ED) at a tertiary hospital in a major urban centre. Individual interviews were conducted (n=15), and a thematic analysis of interview transcripts was completed using a hybrid inductive/deductive approach. Five major themes were identified and described: 1) caregiver management strategies; 2) reasons for going to the ED; 3) treatment and management of AGE in the ED; 4) caregivers' information needs; and 5) additional factors influencing caregivers' experiences and decision-making. A number of subthemes within each major theme were identified and described. This qualitative descriptive study has identified caregiver information needs, preferences, and priorities regarding pediatric AGE. This study also identified inconsistencies in the treatment and management of pediatric AGE at home and in the ED that influence health care utilization and patient outcomes related to pediatric AGE.

Background Little prospectively collected data are available comparing the dietary intake of urea cycle disorder (UCD) patients to UCD treatment guidelines or to healthy individuals. Objective To examine the protein and calorie intakes of UCD subjects who participated in clinical trials of glycerol phenylbutyrate (GPB) and compare these data to published UCD dietary guidelines and nutritional surveys. Design Dietary data were recorded for 45 adult and 49 pediatric UCD subjects in metabolic control during participation in clinical trials of GPB. Protein and calorie intakes were compared to UCD treatment guidelines, average nutrient intakes of a healthy US population based on the National Health and Nutrition Examination Survey (NHANES) and Recommended Daily Allowances (RDA). Results In adults, mean protein intake was higher than UCD recommendations but lower than RDA and NHANES values, while calorie intake was lower than UCD recommendations, RDA and NHANES. In pediatric subjects, prescribed protein intake was higher than UCD guidelines, similar to RDA, and lower than NHANES data for all age groups, while calorie intake was at the lower end of the recommended UCD range and close to RDA and NHANES data. In pediatric subjects height, weight, and body mass index (BMI) Z-scores were within normal range (− 2 to 2). Conclusions Pediatric patients treated with phenylbutyrate derivatives exhibited normal height and weight. Protein and calorie intakes in adult and pediatric UCD subjects differed from UCD dietary guidelines, suggesting that these guidelines may need to be reconsidered. PMID:27014577

Background: Studies from Nigeria on pediatric otorhinolaryngology (ORL) emergencies are rare in literature with most focusing on emergencies involving individual systems. Objective: The aim of this study is to determine the prevalence of all ORL emergencies among children in our region to provide a baseline data for future health planning. Patients and Methods: This is a 1-year retrospective cross-sectional study of patients aged 16 years and below presenting to the Accident and Emergency Department of the Jos University Teaching Hospital, Jos, Nigeria. Results: A total of 203 otolaryngology emergencies were attended of which 129 (63.5%) were pediatric emergencies. Records of 87 patients were retrievable with age range 2 months to 15 years (mean 3.44 years; standard deviation ± 3.35). There were 55 males and 32 females with a male to female ratio of 1.7:1. The majority of cases were aged under 5 years (64; 73.6%). Acute tonsillitis accounted for 32 (36.7%) cases with 6 (6.9%) having peritonsillar abscesses. Acute pharyngitis accounted for 11 (12.6%) presentations followed closely by foreign bodies (FBs) in the ear with 10 (11.5%) presentations. FB in the throat occurred in 4 (4.6%) patients who had removal under general anesthesia. Three (3.4%) cases of maxillofacial injuries occurred as a result of insurgent terror attacks and 3.4% presented following corrosive substance ingestion. Conservative management was commenced in 76 (87.4%) patients, 23 (26.4%) had surgery with 68 (78.2%) admitted and discharged, 18 (20.7%) treated as outpatients, and 1 (1.1%) died on admission. Otolaryngologists attended most (95.4%) patients. Conclusion: Pediatric ORL emergencies are common in our region involving a wide range of pathologies. Expansion is required in the ORL training of the emergency room physician to enhance emergency services. PMID:28469122

The goal of this evaluation was to obtain insight into possible benefits derived from the ABI and to begin developing assessment protocols for pediatric clinical trials. Case study. Tertiary referral center. Pediatric ABI Patient 1 was born with auditory nerve agenesis. Auditory brainstem implant surgery was performed in December, 2005, in Verona, Italy. The child was assessed at the House Ear Institute, Los Angeles, in July 2006 at the age of 3 years 11 months. Follow-up assessment has continued at the HEAR Center in Birmingham, Alabama. Auditory brainstem implant. Performance was assessed for the domains of audition, speech and language, intelligence and behavior, quality of life, and parental factors. Patient 1 demonstrated detection of sound, speech pattern perception with visual cues, and inconsistent auditory-only vowel discrimination. Language age with signs was approximately 2 years, and vocalizations were increasing. Of normal intelligence, he exhibited attention deficits with difficulty completing structured tasks. Twelve months later, this child was able to identify speech patterns consistently; closed-set word identification was emerging. These results were within the range of performance for a small sample of similarly aged pediatric cochlear implant users. Pediatric ABI assessment with a group of well-selected children is needed to examine risk versus benefit in this population and to analyze whether open-set speech recognition is achievable.

Thyrotropin (TSH)-secreting pituitary adenomas are exceedingly rare at the pediatric age and no cases of co-secretion with other pituitary hormones in these tumors have been described in this age range. We present a case of a monomorphous plurihormonal pituitary adenoma that co-secreted TSH and GH in a pediatric patient. A 13-year-old male presented with increasing height velocity (17.75 cm/year, 9.55SD), weight loss, and visual impairment. Initial biochemical evaluations revealed secondary hyperthyroidism. A giant pituitary tumor compressing the surrounding structures was detected by magnetic resonance, and a transsphenoidal surgery was initially performed. Pathological examinations revealed an atypical, monomorphous plurihormonal Pit-1 lineage tumor with mixed features of silent subtype 3 adenoma and acidophil stem cell adenoma. In the postoperative period, secondary hyperthyroidism recurred with high levels of both GH and IGF1. In addition, due to tumor re-growth, a multimodality treatment plan was undertaken including surgery, somatostatin analogs, and radiotherapy. We report the first pediatric case of a plurihormonal TSH- and GH-secreting pituitary adenoma, further expanding the clinical manifestations of pediatric pituitary tumors. Comprehensive pathological evaluation and close follow-up surveillance are crucial to the prompt delivery of the best therapeutic options in the context of this particularly aggressive pituitary tumor.

Background: “Holi” is a spring festival celebrated primarily in the Indian subcontinent and also abroad by expatriate Indians. It is a festival of colors, traditionally celebrated by mutual application of colors in different forms on a particular day of the year. These colors frequently comprise a range of synthetic dyes which have harmful effects on the skin and mucosae. Children take part in this colorful festival with much enthusiasm and vigor, making them prone to develop different “Holi”-related dermatoses. Our objective was to find out the different patterns of “Holi”-related dermatoses in a group of pediatric patients. Methodology: This was a cross-sectional descriptive study carried out over a period of 6 years (2010–2015). Consecutive patients of pediatric age group who attended dermatology outpatient department (OPD) with different dermatoses following application of “Holi” color were included in this study. Results: A total of 63 patients (mean age 11 years; range 1–16 years) were evaluated with a female to male ratio of 1.3:1. Itching is the predominant presenting symptom followed by burning sensation, dryness, scaling, oozing, and loss of hair. Examination revealed that eczematous lesion was the most common (69.8%) reaction pattern followed by xerosis, desquamation, excoriation, erythema, morbilliform eruption, erosion, alopecia, ulceration, acute paronychia, and hyperpigmentation. The face was the most common (76.4%) site of affection. Conclusion: A sizable number of patients of pediatric age group may be affected by “Holi”-related dermatoses necessitating precautionary measures. PMID:27688442

Stenting for aortic coarctation (CoA) has been accepted as an alternative to surgery for adolescents and adults, but only a few case have been reported in Japan. The purpose of this study was to provide a detailed review of Japanese national data on stenting of CoA. In a subanalysis of the data of the Japanese Society of Pediatric Interventional Cardiology (JPIC), we identified 35 patients with CoA who underwent stenting. We analyzed procedural characteristics including factors that may have contributed to hemodynamic effectiveness, and we compared these parameters between the patients under and over 15 years of age. The mean ratio of balloon diameter/minimum lumen diameter (MLD) before stenting was 1.7 (range, 1.2-4.0), and the mean difference between the balloon diameter and the reference vessel diameter was -0.7 mm (range, -5.0 to +3.0 mm). %MLD/balloon diameter, which was defined as [(balloon diameter - MLD after dilation)/balloon diameter] × 100 predicted achievement of <10 mmHg pressure gradient after stenting. The sensitivity and the specificity of its cut-off of 7% were 93% and 47% (AUC, 0.7), respectively. There was no statistical difference between the two age groups under and over 15 years of age, in terms of selection criteria of stent size, balloon type used for deployment and immediate angiographic and hemodynamic result. Stenting for CoA was clinically effective with few complications in Japan, even in patients not fully grown. © 2015 Japan Pediatric Society.

Recurrent respiratory tract infections are one of the most frequent reasons for pediatric visits and hospitalization. Causes of this pathology are multiple ranging from congenital to acquired and local to general. Immune deficiencies are considered as underlying conditions predisposing to this pathology. Our work is about to determine when and how to explore the immune system when facing recurrent respiratory infections. This was based on the records of 53 children hospitalized at the pediatrics unit of Hassan II University Hospital, Fez Morocco. Thirty boys and 23 girls with age ranging from 5 months to 12 years with an average age of 2 years were involved in this study. Bronchial foreign body was the main etiology in children of 3 to 6 year old. Gastro-esophageal reflux, which in some cases is a consequence of chronic cough, as well as asthma were most frequent in infants (17 and 15% respectively). Immune deficiency was described in 7.5% of patients and the only death we deplored in our series belongs to this group. Recurrent respiratory tract infections have multiple causes. In our series they are dominated by foreign body inhalation and gastroesophageal reflux, which in some cases is a consequence of a chronic cough. Immune deficiency is not frequent but could influence the prognosis. Therefore immune explorations should be well codified.

We aimed to evaluate the effects of preoperative urinary catheterization in nephrolithiasis treatment with extracorporeal shock wave lithotripsy (SWL). Patients admitted to the Department of Pediatric Surgery for renal stones between June 2012 and June 2014 were evaluated retrospectively. Patients were divided into 2 groups based on JJ stent placements. Group 1 did not receive JJ stents, while group 2 did. The recorded demographic data for each group included age, gender, stone size, location, sessions, and complications. The Elmed Complit ESWL system was used with 11-13 kV, and 1,000-1,200 shots in patients 2-4 years of age, and 11-14 kV, and 1,000-1,500 shots for patients over 4 years. In group 1, 18 sessions of SWL were performed on 8 female and 2 male children with a mean age of 4.5 (range 2-12) years and stone diameter of 9 (range 7-15) mm. The locations of the renal stones were in the upper pole in 1 patient, 7 in the lower pole, and 2 in the pelvis renalis. Postoperatively, 1 patient had hematuria, 2 had dysuria, and one had a stone in the external urethral meatus. Eighty percent of patients were stone free; there were no fragmentations in 2 patients, and 1 patient discontinued treatment. In group 2, 15 SWL sessions were performed on 5 female and 5 male children aged 4 (range 3-5) and the stone diameter was 9 (range 7-16) mm. The locations of the renal stones were in the upper pole in 6 patients, in the lower pole in 3 patients, and in the ureteropelvic junction in one patient. JJ stents were placed in all patients preoperatively. Postoperatively, 3 patients had hematuria and one had dysuria. At the end of the study, all of the patients were stone free. Statistically, there were no differences in age, gender, stone size, location, and the number of sessions. Our results indicate that SWL without preoperative ureteral stenting is an effective and safe procedure that can be carried out in the pediatric population. Preoperative JJ stenting is unnecessary in patients, especially in those with smaller stone diameters. © 2016 S. Karger AG, Basel.

Studies on adolescents and young adults with acute lymphoblastic leukemia suggest better results when using pediatric protocols for adult patients, while corresponding data for acute myeloid leukemia (AML) are limited. We investigated disease characteristics and outcome for de novo AML patients 10-30 years old treated in pediatric or adult departments. We included 166 patients 10-18 years of age with AML treated according to the pediatric NOPHO-protocols (1993-2009) compared with 253 patients aged 15-30 years treated in hematology departments (1996-2009) in the Nordic countries. The incidence of AML was 4.9/million/year for the age group 10-14 years, 6.5 for 15-18 years, and 6.9 for 19-30 years. Acute promyelocytic leukemia (APL) was more frequent in adults and in females of all ages. Pediatric patients with APL had similar overall survival as pediatric patients without APL. Overall survival at 5 years was 60% (52-68%) for pediatric patients compared to 65% (58-70%) for adult patients. Cytogenetics and presenting white blood cell count were the only independent prognostic factors for overall survival. Age was not an independent prognostic factor. No difference was found in outcome for AML patients age 10-30 years treated according to pediatric as compared to adult protocols. © 2015 Wiley Periodicals, Inc.

Abdominal Non-Hodgkin lymphomas (NHL) are the most common extra nodal presentation of pediatric NHL. Our aim is to assess the role of surgery as a risk factor and to evaluate the impact of risk-adjusted systemic chemotherapy on survival of patients with stages II and III disease. This study included 35 pediatric patients with abdominal NHL treated over five years at South Egypt Cancer Institute (SECI), Assiut University, between January 2005 and January 2010. The data of every patient included: Age, sex, and presentation, staging work up to determine extent of the disease and the type of resection performed, histopathological examination, details of chemotherapy, disease free survival and overall survival. The study included 25 boys and 10 girls with a median age of six years (range: 2.5:15). Thirty patients (86%) presented with abdominal pain, 23 patients (66%) presented with abdominal mass and distention, 13 patients (34%) presented with weight loss, and intestinal obstruction occurred in six patients (17%). The ileo-cecal region and abdominal lymph nodes were the commonest sites (48.5%, 21% respectively). Burkitt's lymphoma was the most common histological type in 29 patients (83%). Ten (28.5%) stage II (group A) and 25 (71.5%) stage III (group B). Complete resections were performed in 10 (28.5%), debulking in 6 (17%) and imaging guided biopsy in 19 (54%). A11 patients received systemic chemotherapy. The median follow up duration was 63 months (range 51-78 months). The parameters that significantly affect the overall survival were stage at presentation complete resection for localized disease. In conclusion, the extent of disease at presentation is the most important prognostic factor in pediatric abdominal NHL. Surgery is restricted to defined situations such as; abdominal emergencies, diagnostic biopsy and total tumor extirpation in localized disease. Chemotherapy is the cornerstone in the management of pediatric abdominal NHL. PMID:24212775

Continuous-flow (CF) ventricular assist devices (VADs) have largely replaced pulsatile-flow VADs in adult patients. However, there are few data on CF VADs among pediatric patients. In this study we aimed to describe the overall use, patients' characteristics and outcomes of CF VADs in this population. The Pediatric Interagency Registry for Mechanical Circulatory Support (PediMACS) is a national registry for U.S. Food and Drug Adminstration (FDA)-approved VADs in patients <19 years of age. Patients undergoing placement of durable CF VADs between September 2012 and June 2015 were included and outcomes were compared with those of adults from the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS). CF VADs were implanted in 109 patients at 35 hospitals. The median age at implantation was 15 years (2.8 to 18.9 years) and median weight was 62 kg (range 16 to 141 kg). The underlying disease was cardiomyopathy in 89 (82%) patients. The INTERMACS level at time of implant was Level 1 in 20 (19%), Level 2 in 64 (61%) and Levels 3 to 7 in 21 (20%) patients. Most were implanted as LVADs (n = 102, 94%). Median duration of support was 2.3 months (range <1 day to 28 months). Serious adverse event rates were low, including neurologic dysfunction (early event rate 4.1 per 100 patient-months with 2 late events). Competing outcomes analysis at 6 months post-implant indicated 61% transplanted, 31% alive with device in place and 8% death before transplant. These outcomes compared favorably with the 3,894 adults supported with CF VADs as a bridge to transplant. CF VADs are commonly utilized in older children and adolescents, with excellent survival rates. Further study is needed to understand impact of patient and device characteristics on outcomes in pediatric patients. Copyright © 2016 International Society for Heart and Lung Transplantation.

To evaluate the technical feasibility and clinical efficacy of osteoid osteoma (OO) cryoablation in a large, pediatric/adolescent cohort. An electronic medical record and imaging archive review was performed to identify all cryoablations performed for OOs between 2011 and 2015 at a single tertiary care pediatric hospital. The subsequent analysis included 29 patients with suspected OOs treated by cryoablation (age range, 3-18 y; mean age, 11.3 y; 17 boys; 12 girls). Conventional CT guidance was used in 22 procedures; cone-beam CT guidance was used in 7 procedures. Follow-up data were obtained via a standardized telephone questionnaire (23/29 patients; 79.3%) and clinical notes (5/29 patients; 17.2%). One patient was lost to follow-up. Technical success was achieved in 100% of patients (29/29). Immediate clinical success (cessation of pain and nonsteroidal antiinflammatory drug [NSAID] use within 1 mo after the procedure) was achieved in 27/28 patients (96.4%). Short-term clinical success (cessation of pain and NSAID use for > 3 mo after the procedure) was achieved in 24/25 patients (96%). Long-term clinical success (cessation of pain and NSAID use for > 12 mo after the procedure) was achieved in 19/21 patients (90.5%). Median pain scale score before the procedure was 10 (range, 5-10); median pain scale score after the procedure was 0 (range, 0-8; P < .0001). There were 6 minor complications (21%) and no major complications. Image-guided cryoablation is a technically feasible, clinically efficacious therapeutic option for children and adolescents with symptomatic OO. Copyright © 2016 SIR. Published by Elsevier Inc.

2012-07-01

The purpose of this study was to investigate the possibility of estimating pediatric thyroid doses from CT using surface neck doses. Optically stimulated luminescence dosimeters were used to measure the neck surface dose of 25 children ranging in ages between one and three years old. The neck circumference for each child was measured. The relationship between obtained surface doses and thyroid dose was studied using acrylic phantoms of various sizes and with holes of different depths. The ratios of hole-to-surface doses were used to convert patients' surface dose to thyroid dose. ImPACT software was utilized to calculate thyroid dose after applying the appropriate age correction factors. A paired t-test was performed to compare thyroid doses from our approach and ImPACT. The ratio of thyroid to surface dose was found to be 1.1. Thyroid doses ranged from 20 to 80 mGy. Comparison showed no statistical significance (p = 0.18). In addition, the average of surface dose variation along the z-axis in helical scans was studied and found to range between 5% (in 10 cm diameter phantom/24 mm collimation/pitch 1.0) and 8% (in 16 cm diameter phantom/12 mm collimation/pitch 0.7). We conclude that surface dose is an acceptable predictor for pediatric thyroid dose from CT. The uncertainty due to surface dose variability may be reduced if narrower collimation is used with a pitch factor close to 1.0. Also, the results did not show any effect of thyroid depth on the measured dose.

The geographic relationship between pediatric anesthesiologists and the pediatric population has potentially important clinical and policy implications. In the current study, we describe the geographic distribution of pediatric anesthesiologists relative to the US pediatric population (0-17 years) and a subset of the pediatric population (0-4 years). The percentage of the US pediatric population that lives within different driving distances to the nearest pediatric anesthesiologist (0 to 25 miles, >25 to 50 miles, >50 to 100 miles, >100 to 250 miles, and >250 miles) was determined by creating concentric driving distance service areas surrounding pediatric anesthesiologist practice locations. US Census block groups were used to determine the sum pediatric population in each anesthesiologist driving distance service area. The pediatric anesthesiologist-to-pediatric population ratio was then determined for each of the 306 hospital referral regions (HRRs) in the United States and compared with ratios of other physician groups to the pediatric population. All geographic mapping and analysis was performed using ArcGIS Desktop 10.2.2 mapping software (Redlands, CA). A majority of the pediatric population (71.4%) lives within a 25-mile drive of a pediatric anesthesiologist; however, 10.2 million US children (0-17 years) live greater than 50 miles from the nearest pediatric anesthesiologist. More than 2.7 million children ages 0 to 4 years live greater than 50 miles from the nearest identified pediatric anesthesiologist. The median ratio of pediatric anesthesiologists to 100,000 pediatric population at the HRR level was 2.25 (interquartile range, 0-5.46). Pediatric anesthesiologist geographic distribution relative to the pediatric population by HRR is lower and less uniform than for all anesthesiologists, neonatologists, and pediatricians. A substantial proportion of the US pediatric population lives greater than 50 miles from the nearest pediatric anesthesiologist, and pediatric anesthesiologist-to-pediatric population ratios by HRR vary widely across the United States. These findings are important given that the new guidelines from the American College of Surgeons Children's Surgery Verification™ Quality Improvement Program state that pediatric anesthesiologists must care for a subset of pediatric patients. Because of the geographic distribution of pediatric anesthesiologists relative to the pediatric population, access to care by a pediatric anesthesiologist may not be feasible for all children, particularly for those with limited resources or in emergent situations.

Stein, Jill M.; Walkup, Laura L.; Brody, Alan S.; Fleck, Robert J.

2016-01-01

Background The use of quantitative CT analysis in children is limited by lack of normal values of lung parenchymal attenuation. These characteristics are important because normal lung development yields significant parenchymal attenuation changes as children age. Objective To perform quantitative characterization of normal pediatric lung parenchymal X-ray CT attenuation under routine clinical conditions in order to establish a baseline comparison to that seen in pathological lung conditions. Materials and methods We conducted a retrospective query of normal CT chest examinations in children ages 0–7 years from 2004 to 2014 using standard clinical protocol. During these examinations semi-automated lung parenchymal segmentation was performed to measure lung volume and mean lung attenuation. Results We analyzed 42 CT examinations in 39 children, ages 3 days to 83 months (mean ± standard deviation [SD] = 42±27 months). Lung volume ranged 0.10–1.72 liters (L). Mean lung attenuation was much higher in children younger than 12 months, with values as high as −380 Hounsfield units (HU) in neonates (lung volume 0.10 L). Lung volume decreased to approximately −650 HU by age 2 years (lung volume 0.47 L), with subsequently slower exponential decrease toward a relatively constant value of −860 HU as age and lung volume increased. Conclusion Normal lung parenchymal X-ray CT attenuation decreases with increasing lung volume and age; lung attenuation decreases rapidly in the first 2 years of age and more slowly thereafter. This change in normal lung attenuation should be taken into account as quantitative CT methods are translated to pediatric pulmonary imaging. PMID:27576458

The characteristics of adult patients with chronic active Epstein-Barr virus infection are poorly recognized, hindering early diagnosis and an improved prognosis. We studied 54 patients with adult-onset chronic active Epstein-Barr virus infection diagnosed between 2005 and 2015. Adult onset was defined as an estimated age of onset of 15 years or older. To characterize the clinical features of these adults, we compared them to those of 75 pediatric cases (estimated age of onset <15 years). We compared the prognosis of adult-onset chronic active Epstein-Barr virus infection with that of patients with nasal-type (n=37) and non-nasal-type (n=45) extranodal NK/T-cell lymphoma. The median estimated age of onset of these lymphomas was 39 years (range, 16-86 years). Compared to patients with pediatric-onset disease, those in whom the chronic active Epstein-Barr virus infection developed in adulthood had a significantly decreased incidence of fever ( P =0.005), but greater frequency of skin lesions ( P <0.001). Moreover, hypersensitivity to mosquito bites and the occurrence of hydroa vacciniforme were less frequent in patients with adult-onset disease ( P <0.001 and P =0.0238, respectively). Thrombocytopenia, high Epstein-Barr virus nuclear antigen antibody titer, and the presence of hemophagocytic syndrome were associated with a poor prognosis ( P =0.0087, P =0.0236, and P =0.0149, respectively). Allogeneic hematopoietic stem cell transplantation may improve survival ( P =0.0289). Compared to pediatric-onset chronic active Epstein-Barr virus infection and extranodal NK/T-cell lymphoma, adult-onset chronic active Epstein-Barr virus infection had a poorer prognosis ( P <0.001 and P =0.0484, respectively). Chronic active Epstein-Barr virus infection can develop in a wide age range, with clinical differences between adult-onset and pediatric-onset disease. Adult-onset chronic active Epstein-Barr virus infection is a disease with a poor prognosis. Further research will be needed. Copyright © 2018 Ferrata Storti Foundation.

Functional gastrointestinal disorders (FGIDs) are common in children of all ages and comprise of a wide range of conditions related to the gastrointestinal tract that cannot be attributed to structural or biochemical abnormalities. FGIDs are diagnosed according to the symptom-based Rome criteria. Areas covered: In 2016, the revised pediatric Rome IV criteria were published, these revised criteria are discussed in this review article. For the youngest age group (neonates/toddlers), the criteria for infant colic have undergone the most notable revisions. The most prominent changes in Rome IV were made in the criteria for children/adolescents, with the definition of two new FGIDs (functional nausea and functional vomiting) and the restructuring of the criteria for functional abdominal pain disorders, including the definition of FGID subtypes for functional dyspepsia and irritable bowel syndrome. Expert commentary: Overall, the Rome IV have been refined and are expected to improve the process of diagnosing FGIDs in the pediatric population and to better facilitate the healthcare professional in distinguishing different clinical entities. These changes will likely benefit future research and clinical care.

This study examined pediatric dentists' perspectives on the types of dental services general dentists provide to children who are 0-3 years old. A web-based survey was sent to 5185 pediatric dentists and 769 (14.8%) responded. Among the respondents, 58% agreed with general dentists' providing an age 1 dental visit. Only 24% agreed with general dentists' performing complex behavior management techniques, such as sedation, to patients aged 0-3 years. Those respondents who taught pediatric dentistry full time were more likely to agree with general dentists' providing an age 1 dental visit (P = 0.0088). Those who reported that their own dental school had adequately prepared them for this type of age 1 visit were also more in agreement (P < 0.0001). The results of this study promote better understanding of pediatric dentists' perceptions of the level of collaboration between general dentists and pediatric dentists; the types of oral health services general dentists can provide for children aged 0-3 years; and the anticipated level of competency of entry-level general dentists.

Development of pediatric medications and devices is complicated by differences in pediatric physiology and pathophysiology (both compared with adults and within the pediatric age range), small patient populations, and practical and ethical challenges to designing clinical trials. This article summarizes the discussions that occurred at a Cardiac Safety Research Consortium-sponsored Think Tank convened on December 10, 2010, where members from academia, industry, and regulatory agencies discussed important issues regarding pediatric cardiovascular safety of medications and cardiovascular devices. Pediatric drug and device development may use adult data but often requires additional preclinical and clinical testing to characterize effects on cardiac function and development. Challenges in preclinical trials include identifying appropriate animal models, clinically relevant efficacy end points, and methods to monitor cardiovascular safety. Pediatric clinical trials have different ethical concerns from adult trials, including consideration of the subjects' families. Clinical trial design in pediatrics should assess risks and benefits as well as incorporate input from families. Postmarketing surveillance, mandated by federal law, plays an important role in both drug and device safety assessment and becomes crucial in the pediatric population because of the limitations of premarketing pediatric studies. Solutions for this wide array of issues will require collaboration between academia, industry, and government as well as creativity in pediatric study design. Formation of various epidemiologic tools including registries to describe outcomes of pediatric cardiac disease and its treatment as well as cardiac effects of noncardiovascular medications, should inform preclinical and clinical development and improve benefit-risk assessments for the patients. The discussions in this article summarize areas of emerging consensus and other areas in which consensus remains elusive and provide suggestions for additional research to further our knowledge and understanding of this topic.

To evaluate a protocol for rapid sequence intubation (RSI) for pediatric patients in a Level 1 trauma center. Retrospective review of prospectively gathered Continuing Quality Improvement (CQI) data at an inner city Level 1 trauma center with an emergency medicine residency program. Protocols for RSI were established prior to initiating the study. All pediatric intubations at the center from February 1996 to February 2000 were included. Statistical analysis included descriptive statistics for categorical data and Chi-square for comparisons between groups. Over the 4-year study period there were 83 pediatric intubations ranging in age from 18 months to 17 years; mean age 8.6. All had data collected at the time of intubation. There were 20 (24%) females and 62 (76%) males (p<0.001). Reasons for intubation were related to trauma in 71 (86%) and medical reasons in 12 (14%) (p<0.001). Of the trauma intubations 7 (10%) were for gunshot wounds, 39 (55%) were secondary to MVCs, and the remainder (25; 35%) were from assaults, falls, and closed head injuries. The non-trauma intubations were for smoke inhalation, overdose, seizure, HIV related complications, eclampsia, and near drowning. Intubations were successful with one attempt in 65 (78%) cases. No surgical airways were necessary. Rocuronium was used in 4 cases. Protocol deviations did not lead to complications. This protocol based pediatric rapid sequence intubation method worked well in an EM residency program. More intubations were in males and more were necessary due to trauma in this group.

Objectives: The recurrence of pediatric nephrolithiasis, the morbidity of repeated open surgical treatment as well as our experience in percutaneous nephrolithotomy (PNL) in adult patients, all derived us to shift to PNL for managing renal stones >1.5 cm in pediatric patients. Our aim of this study is to evaluate the safety and efficacy of PNL in pediatric patients. Materials and Methods: During the period of the month between May 2011 and April 2013, 38 children (47 renal units) underwent PNL for renal stones 1.5-5 cm in length. Patient demographics, stone characteristics, and clinical outcome were prospectively studied. Data of those who underwent conventional and tubeless PNL were compared. Median follow-up period was 12 months (range: 6-24). Results: The median age at presentation was 8-year (range: 3-12). The operative time ranged from 30 to 120 min (median 90). Overall stone clearance rate was 91.5% after single PNL. The median hospital stay was 3 days. Auxiliary procedures were successful for the remaining 4 patients (nephroscopic clearance in one and shockwave lithotripsy in 3). Tubeless PNL was performed in 17 renal units with a comparable outcome to conventional ones. The perioperative complications were noted in 5/47 (10.6%) of all procedures (Clavien Grade II in 4 and Clavien Grade IIIa in 1) and were managed conservatively. Conclusions: Percutaneous nephrolithotomy for renal stones in pediatric patients is safe and feasible if performed by a well-experienced endourologist. Tubeless PNL is a better choice for children.

The clinical effectiveness of negative pressure wound therapy for the management of acute and chronic wounds is well documented in the adult population but information regarding its use in the pediatric population is limited. A retrospective, descriptive study was conducted to examine the clinical outcomes of using negative pressure wound therapy in the treatment of pediatric wounds. The medical records of 24 consecutive pediatric patients receiving negative pressure wound therapy were reviewed. Demographic data, wound etiology, time to closure, closure method, duration of negative pressure wound therapy, complications, dressing change frequency, dressing type used, and pressure settings were analyzed. All categorical variables in the dataset were summarized using frequency (count and percentages) and all continuous variables were summarized using median (minimum, maximum). The 24 pediatric patients (mean age 8.5 years [range 14 days to 18 years old]) had 24 wounds - 12 (50%) were infected at baseline. Sixteen patients had hypoalbuminemia and six had exposed hardware and bone in their wounds. Twenty-two wounds reached full closure in a median time of 10 days (range 2 to 45) following negative pressure wound therapy and flap closure (11), split-thickness skin graft (three), secondary (four), and primary (four) closure. Pressures used in this population ranged from 50 to 125 mm Hg and most wounds were covered with reticulated polyurethane foam. One patient developed a fistula during the course of negative pressure wound therapy. When coupled with appropriate systemic antibiotics, surgical debridement, and medical and nutritional optimization, in this population negative pressure wound therapy resulted in rapid granulation tissue and 92% successful wound closure. Future neonatal and pediatric negative pressure wound therapy usage registries and prospective studies are needed to provide a strong evidence base from which treatment decisions can be made in the management of these challenging cases, especially pertaining to the safety and efficacy of pressure settings, dressings, and interposing contact layer selection.

Pediatric population has increasing incidence of renal calculus and it is estimated to be around 50/10,000 population. The treatment of choice for large and complex stone in anomalous kidney is percutaneous nephrolithotomy (PCNL). The fate of insignificant residual fragment after PCNL in pediatric patients is not well documented. Here, we are reporting our long-term experience and follow-up of insignificant residual fragment in pediatric patients with anomalous kidney in comparison to normal kidney. Intuitional ethical approval was taken. A retrospective analysis of PCNL in pediatric (<18 years) anomalous kidney was performed from 2001 to 2013. The data of 52 pediatric patients with anomalous kidney (group B) have been compared to 251 normal kidneys (group A). The mean age of the patients was 7.83 + 3.45 (range 3-18) in group A and 8.21 ± 3.25 (range 5-18) in group B. The mean size of the insignificant residual fragment was 2.2 + 0.5 mm (1-4) in group A and 2.1 + 0.6 mm (range 1-4) in group B. Most of these residual fragments were single in number (72.55 vs. 67.30%, respectively). 54.98% children in group A and 67.30% in group B were symptomatic in the follow-up. Stone size was increased, stable and spontaneously passed in 49.8 vs. 71.15, 22.7 vs. 19.23 and 27.49 vs. 9.61% (p < 0.03), respectively, over mean follow-up of 50.34 months. Insignificant residual fragments in children are notorious for regrowth (49.8% in normal and 71.15% in anomalous kidney) in future. Most of the children will require symptomatic treatment (55.37 vs. 82.69%) or reintervention (39 vs. 46%) for insignificant residual fragment.

We aimed to present the complications of auditory brain stem implantations (ABI) in pediatric patients which were performed via retrosigmoid approach. Between March 2007 and February 2010, five prelingually deaf children underwent ABI (Medel device) operation via retrosigmoid approach. All children had severe cochlear malformations. The ages ranged from 20 months to 5 years. The perioperative complications encountered in 2 patients were evaluated retrospectively. No intraoperative complication was observed in the patients. Cerebrospinal fluid (CSF) leakage was the most common postoperative complication that was seen in 2 patients. The CSF leak triggered a cascade of comorbidities, and elongated the hospitalization. Pediatric ABI surgery can lead to morbidity. The CSF leak is the most common complication encountered in retrosigmoid approach. The other complications usually result from long-term hospital stay during treatment period of the CSF leak. Therefore, every attempt must be made to prevent occurrence of CSF leaks in pediatric ABI operations. Copyright © 2011 S. Karger AG, Basel.

We present recent data on the bacteriological profile and antibiotic susceptibility of uropathogenic bacteria isolated in children and newborns in our region over the past 2 years. A retrospective study on the positive urine cultures from pediatric and neonatal populations during 2012-2013. Bacteria were identified using conventional methods. Susceptibility testing was performed and interpreted as recommended by the committee of the susceptibility of the French Society of Microbiology (CA-SFM). We collected 1879 non-redundant bacteria with more than 73% Escherichia coli. Children and infants (mean age, 32 months [range, 1 month to 14 years]) accounted for 84% of the bacteria collected and newborns (mean age, 12 days [range, 1 day to 1 month]) 16%. A female predominance was observed in the pediatric population (M:F sex ratio, 3.2), whereas for the neonatal population, the proportions were almost identical in both sexes (M:F sex ratio, 1.1). Most of the positive urine cultures (n=1234) were from the community. Hospitalized patients (n=636) were divided into pediatric (60%) and neonatal units (40%). Five bacterial genera dominated the bacteriological profile: E. coli, Klebsiella sp., Proteus sp., Enterobacter sp., and Enterococcus. The susceptibility of the main BUP antibiotics used for treatment of frequent UTI showed the effectiveness of furadoine, imipenem, fosfomycin, and colistin. Amoxicillin kept constant activity against Enterococcus and Streptococcus agalactiae. The rates of resistance of Enterobacteriaceae to beta-lactam antibiotics were high, especially in the neonatal population. The production of extended-spectrum beta-lactamase (ESBL) was noted in 12.8% of pediatric Enterobacteria vs. 22.6% of the neonatal strains. For community Enterobacteriaceae, the activity of beta-lactam antibiotics was limited with 11.2% resistance to third-generation cephalosporins (C3G), including 8.6% ESBL production. The impact of widespread use of beta-lactam antibiotics in neonatal and pediatric environments is felt. Colistin, imipenem, and fosfomycin are the most frequently used antibiotics active against bacteria responsible for neonatal and pediatric UTI; however, they cannot be used as probabilistic treatment. Nitrofurans seem to be active antibiotics on UTI, but they present limits in their use in neonatal and pediatric populations. Their indication in case of pyelonephritis should be discussed.

To evaluate the efficacy of pars plana vitrectomy (PPV) as an anti-inflammatory therapy in pediatric recurrent intermediate uveitis. A retrospective study evaluated the long-term results of PPV indicated for intermediate uveitis with a mean observation period of 10.3 years (range 7-15.6 years) in 6 children (mean age 8 years, range 6-12 years). Pars plana vitrectomy was performed on 10 eyes in the standard manner and was initiated by vitreous sampling for laboratory examination. Data recorded were perioperative or postoperative vitrectomy complications, anatomic and functional results of PPV, and preoperative and postoperative best-corrected Snellen visual acuity. No perioperative or postoperative complications were observed. Bacteriologic, virologic, mycotic, and cytologic analysis of the vitreous was negative in all tested children. Five eyes were subsequently operated on for posterior subcapsular cataracts. An average preoperative visual acuity of 0.32 improved to an average postoperative visual acuity of 0.8. In the case of systemic immunosuppressive treatment failure in pediatric uveitis, particularly in eyes with cystoid macular edema, we recommend PPV relatively early.

To outline the characteristics, clinical course, and outcome of pediatric patients requiring mechanical ventilation with influenza A/H1N1 infection in Japan. Prospective case registry analysis. Eleven pediatric or general intensive care units in Japan. Consecutive patients infected with A/H1N1, aged from 1 month to 16 yrs old admitted to the intensive care unit for mechanical ventilation between July 2009 and March 2010. None. Eighty-one children, aged 6.3 [0.8-13.6] (median [interquartile range]) years, were enrolled. Seventy-four (91%) had mechanical ventilation with tracheal intubation. Median duration of mechanical ventilation was 4 days (range 0.04-87) and 18 patients (23%) required mechanical ventilation >7 days. Two patients (2%) required extracorporeal membrane oxygenation. The in-hospital mortality was 1%. Forty-one patients (50%) had at least one underlying chronic condition, including 31 with asthma. Associated clinical symptoms and diagnosis were as follows: acute respiratory distress syndrome (9%), asthma or bronchitis (37%), pneumonia (68%) with 8 (14%) having bacterial pneumonia, neurological symptoms (32%), myocarditis (2%), and rhabdomyolysis (1%). Therapeutic interventions include inotropic support (21%), methylprednisolone therapy (33%), and antimicrobial therapy (88%). Multivariate analysis revealed that inotropic support was the only statistically significant factor associated with mechanical ventilation for more than a week (odds ratio 5.5, 95% confidence interval 1.5-20.5, p = .005). The clinical presentations of pediatric patients requiring mechanical ventilation for A/H1N1 in Japan were diverse. In-hospital mortality of this population was remarkably low. Rapid access to medical facilities in combination with early administration of antiviral agents may have contributed to the low mortality in this population.

Maintaining long-term central venous catheters (CVCs) in children undergoing chemotherapy can be challenging. Guidewire catheter exchange (GCE) replaces a CVC without repeat venipuncture. This study evaluated the indications, success rate, and complications of GCE in a large cohort of pediatric cancer patients. Medical records of pediatric cancer patients who underwent GCE at our institution between 2003 and 2013 were retrospectively reviewed. Variables analyzed included gender, age at GCE, primary cancer diagnosis, indication for GCE, absolute neutrophil count (ANC) at GCE, vein used, success rate, and postoperative complications (<30 days after exchange). A total of 435 GCEs performed in 407 patients (230 males and 177 females) were reviewed. Median age at GCE was 8 years (range, 0.2-24). Acute lymphoblastic leukemia was the most common diagnosis (50.6%). The primary indication for GCE was the desire to have an alternative type of CVC (71%). Other indications included catheter displacement (17%), catheter malfunction (11%), and catheter infection (1%). Median ANC at GCE was 2,581/mm(3) (range, 0-43,400). Left subclavian vein was more commonly used (57.7%). The success rate of GCE was 93.4% (406 of 435 procedures, 95% confidence interval: 91.0-97.5%). A total of 33 (7.5%) postoperative complications occurred including central line associated bloodstream infection (CLABSI) (n = 20, 4.5%), catheter dislodgement (n = 6, 1.4%), and catheter malfunction (n = 7, 1.6%). We conclude that GCE in pediatric cancer patients is associated with a high success rate and a low risk of complications. The most common postoperative complication, CLABSI, occurred at a rate significantly lower than following de novo CVC placement. © 2016 Wiley Periodicals, Inc.

To study long term outcome of bilateral congenital and developmental cataract surgery. 258 pediatric cataract operated eyes of 129 children. Children who underwent pediatric cataract surgery in 2004-8 were traced and examined prospectively in 2010-11. Demographic and clinical factors were noted from retrospective chart readings. All children underwent visual acuity estimation and comprehensive ocular examination in a standardized manner. L. V. Prasad Child Vision Function scores (LVP-CVF) were noted for before and after surgery. Statistical analysis was done with SPSS version 16 including multi-variate analysis. Children aged 9.1 years (std dev 4.6, range 7 weeks-15 years) at the time of surgery. 74/129 (57.4%) were boys. The average duration of follow-up was 4.4 years (stddev 1.6, range 3-8 years). 177 (68.6%) eyes had vision <3/60 before surgery, while 109 (42.2%) had best corrected visual acuity (BCVA) >6/18 and 157 (60.9%) had BCVA >6/60 3-8 years after surgery. 48 (37.2%) had binocular stereoacuity <480 sec of arc by TNO test. Visual outcome depended on type of cataract (P = 0.004), type of cataract surgery (P < 0.001), type of intra-ocular lens (P = 0.05), age at surgery (P = 0.004), absence of post-operative uveitis (P = 0.01) and pre-operative vision (P < 0.001), but did not depend on delay (0.612) between diagnosis and surgery. There was a statistically significant improvement for all the 20 questions of the LVP-CVF scale (P < 0.001). Pediatric cataract surgery improved the children's visual acuity, stereo acuity and vision function. Developmental cataract, use of phacoemulsification, older children and those with better pre-operative vision had betterlong-termoutcomes.

Long-acting reversible contraceptive (LARC) methods can prevent teen pregnancy yet remain underutilized by adolescents in the United States. Pediatric providers are well positioned to discuss LARCs with adolescents, but little is known about how counseling should occur in pediatric primary care settings. We explored adolescent womens' attitudes and experiences with LARCs to inform the development of adolescent-centered LARC counseling strategies. Qualitative analysis of one-on-one interviews. Participants were recruited from 2 urban school-based, primary care centers. Thirty adolescent women aged 14-18 years, diverse in race/ethnicity, and sexual experience. Interviews were audio-recorded, transcribed, and coded using inductive and deductive coding. Major themes were identified to integrate LARC-specific adolescent preferences into existing counseling approaches. Participants (mean age, 16.2 years; range, 14-18 years) represented a diverse range of racial and/or ethnic identities. Half (15/30) were sexually active and 17% (5/30) reported current or past LARC use. Five themes emerged regarding key factors that influence LARC choice, including: (1) strong preferences about device-specific characteristics; (2) previous exposure to information about LARCs from peers, family members, or health counseling sessions; (3) knowledge gaps about LARC methods that affect informed decision-making; (4) personal circumstances or experiences that motivate a desire for effective and/or long-acting contraception; and (5) environmental constraints and supports that might influence adolescent access to LARCs. We identified 5 factors that influence LARC choice among adolescent women and propose a framework for incorporating these factors into contraceptive counseling services in pediatric primary care settings.

Chronic migraine is common in pediatrics and generally disabling. In adults, infiltration of the area around the greater occipital nerve can provide short- to medium-term benefit in some patients. This study reports the efficacy of greater occipital nerve infiltrations in pediatric patients with chronic primary headache disorders. Retrospective chart review of patients <18 years with a chronic primary headache disorder undergoing a first-time injection. Infiltrations were unilateral and consisted of a mixture of methylprednisolone acetate, adjusted for weight, and lidocaine 2%. Forty-six patients were treated. Thirty-five (76%) had chronic migraine, 9 (20%) new daily persistent headache (NDPH), and 2 (4%) a chronic trigeminal autonomic cephalalgia. Medication overuse was present in 26%. Ages ranged from 7 to 17 years. Follow-up data were available for 40 (87%). Overall, 53% (21/40) benefitted, and 52% (11/21) benefitted significantly. Benefit onset ranged from 0 to 14 days, mean 4.7 (SD 4.3), with mean benefit duration of 5.4 (SD 4.9) weeks. In chronic migraine, 62% (18/29) benefitted, and 56% (10/18) significantly benefitted. In NDPH, 33% (3/9) benefitted; 33% (n = 1) significantly. Neither child with a chronic trigeminal autonomic cephalalgia benefitted. In logistic regression modeling, medication overuse, age, sex, and sensory change in the distribution of the infiltrated nerve did not predict outcome. There were no serious side effects. Greater occipital nerve injections benefitted 53% of pediatric patients with chronic primary headache disorders. Efficacy appeared greater in chronic migraine than NDPH. Given the benign side effect profile, a greater occipital nerve infiltration seems appropriate before more aggressive approaches. Copyright © 2014 Elsevier Inc. All rights reserved.

The combination of the severity of pediatric-onset inflammatory bowel disease (IBD) phenotypes and the need for intense medical treatment may increase the risk of malignancy and mortality, but evidence regarding the extent of the problem is scarce. Therefore, the Porto Pediatric IBD working group of ESPGHAN conducted a multinational-based survey of cancer and mortality in pediatric IBD. A survey among pediatric gastroenterologists of 20 European countries and Israel on cancer and/or mortality in the pediatric patient population with IBD was undertaken. One representative from each country repeatedly contacted all pediatric gastroenterologists from each country for reporting retrospectively cancer and/or mortality of pediatric patients with IBD after IBD onset, during 2006-2011. We identified 18 cases of cancers and/or 31 deaths in 44 children (26 males) who were diagnosed with IBD (ulcerative colitis, n = 21) at a median age of 10.0 years (inter quartile range, 3.0-14.0). Causes of mortality were infectious (n = 14), cancer (n = 5), uncontrolled disease activity of IBD (n = 4), procedure-related (n = 3), other non-IBD related diseases (n = 3), and unknown (n = 2). The most common malignancies were hematopoietic tumors (n = 11), of which 3 were hepatosplenic T-cell lymphoma and 3 Ebstein-Barr virus-associated lymphomas. Cancer and mortality in pediatric IBD are rare, but cumulative rates are not insignificant. Mortality is primarily related to infections, particularly in patients with 2 or more immunosuppressive agents, followed by cancer and uncontrolled disease. At least 6 lymphomas were likely treatment-associated by virtue of their phenotype.

Collected data included age, gender, unilateral vs bilateral C/SC fracture, presence of concomitant fracture, velocity of injury, and treatment modality. Tertiary care children's hospital. Of 164 patients with mandibular fractures, 83 (50.6%) had C/SC fractures, of which 45 (54.2%) completed the questionnaire. Helkimo Anamnestic Dysfunction Index (A(i)) quantification of TMJ dysfunction after C/SC fracture and treatment modality of C/SC fractures. Of the 164 patients, 122 (74.4%) were male (median age, 10.4 years; age range, 0.6-19.0 years). Of the 83 patients with C/SC fractures, 61 (73.5%) were male (median age, 9.1 years; age range, 1.1-18.7 years); 66 (79.5%) had unilateral fractures and 17 (20.5%) had bilateral fractures. The A(i) distribution of the 45 patients who completed the questionnaire was as follows: 15 (33.3%) none, 6 (13.3%) mild, and 24 (53.3%) severe. Females have more severe dysfunction than do males (95% confidence interval, 1.6-140.0; P = .02). No other significant predictors of treatment modality or TMJ dysfunction were identified. Patients with bilateral fracture are 8.1 times (95% confidence interval, 1.0-66.1 times; P = .05) more likely to have closed reduction than are those with unilateral fracture. This is one of the largest series of pediatric C/SC fractures reported in the recent literature. Findings are significant for increased severity of TMJ dysfunction in females and higher incidence of closed reduction in patients with bilateral C/SC fracture.

Advanced Automatic Crash Notification (AACN) uses vehicle telemetry data to predict risk of serious injury among motor vehicle crash occupants and can thus improve the accuracy with which injured children are triaged by first responders. To better define serious injury for AACN systems (which typically use Abbreviated Injury Scale [AIS] metrics), an age-specific approach evaluating severity, time sensitivity (TS), and predictability of injury has been developed. This study outlines the development of the TS score. The 95% most frequent AIS 2+ injuries in a national motor vehicle crash data set spanning 2000 to 2011 were determined for the following age groups: 0 to 4, 5 to 9, 10 to 14, and 15 to 18 years. For each age-specific injury, clinicians with pediatric trauma expertise were asked if treatment at a trauma center was required and were asked about the urgency of treatment. A TS score (range 0-1) was calculated by combining the mean trauma center decision and urgency scores. A total of 30 to 32 responses were obtained for each age-specific injury. The most frequent motor vehicle crash-induced injuries in the younger groups received significantly higher scores than those in the older groups (median TS score 0 to 4 years: 0.89, 5-9 years: 0.87, 10-14 years: 0.82, 15-18 years: 0.72, P < .001). Large variations in TS existed within each AIS severity level; for example, scores among AIS 2 injuries in 0- to 4-year-olds ranged from 0.12 to 0.98. The TS of common pediatric injuries varies on the basis of age and may not be accurately reflected by AIS metrics. AIS may not capture all aspects of injury that should be considered by AACN systems.

To evaluate the clinicopathologic features of pediatric mucoceles diagnosed in two public institutions in Brazil during an 18-year period. Clinical data (age, sex, history of trauma, location, and size) of 138 cases of mucoceles in children 0 to 16 years of age were obtained from medical records. The lesions were classified as mucus extravasation phenomenon and mucus retention phenomenon, depending on the presence of epithelial lining in the microscopic analysis. Mucoceles made up 24.5% of the oral pediatric lesions diagnosed in the period of study. Age at diagnosis ranged from 0.4 to 16.0 years, with a mean age of 10.8 years. Of the total of mucoceles, 87 were observed in females and 51 in males. The lower lip was the most commonly affected site, and a history of trauma was related by 87% of the patients. Histologically, 96.4% of mucoceles were diagnosed as mucus extravasation phenomenon. Cases of mucus retention phenomenon were relatively more common in the floor of the mouth, since one in three lesions in this location belonged to this histologic type. Regarding lesions in the lower lip, only 2.65% were diagnosed as mucus retention phenomenon. Trauma is the main etiologic factor involved in the development of mucoceles in children. The mucus extravasation phenomenon is the most common histologic type in this age group. Although rare, the retention type seems to be more common in lesions on the floor of the mouth.

"Not just little adults": qualitative methods to support the development of pediatric patient-reported outcomes.

PubMed

Arbuckle, Rob; Abetz-Webb, Linda

The US FDA and the European Medicines Agency (EMA) have issued incentives and laws mandating clinical research in pediatrics. While guidances for the development and validation of patient-reported outcomes (PROs) or health-related quality of life (HRQL) measures have been issued by these agencies, little attention has focused on pediatric PRO development methods. With reference to the literature, this article provides an overview of specific considerations that should be made with regard to the development of pediatric PRO measures, with a focus on performing qualitative research to ensure content validity. Throughout the questionnaire development process it is critical to use developmentally appropriate language and techniques to ensure outcomes have content validity, and will be reliable and valid within narrow age bands (0-2, 3-5, 6-8, 9-11, 12-14, 15-17 years). For qualitative research, sample sizes within those age bands must be adequate to demonstrate saturation while taking into account children's rapid growth and development. Interview methods, interview guides, and length of interview must all take developmental stage into account. Drawings, play-doh, or props can be used to engage the child. Care needs to be taken during cognitive debriefing, where repeated questioning can lead a child to change their answers, due to thinking their answer is incorrect. For the PROs themselves, the greatest challenge is in measuring outcomes in children aged 5-8 years. In this age range, while self-report is generally more valid, parent reports of observable behaviors are generally more reliable. As such, 'team completion' or a parent-administered child report is often the best option for children aged 5-8 years. For infants and very young children (aged 0-4 years), patient rating of observable behaviors is necessary, and, for adolescents and children aged 9 years and older, self-reported outcomes are generally valid and reliable. In conclusion, the development of PRO measures for use in children requires careful tailoring of qualitative methods, and performing research within narrow age bands. The best reporter should be carefully considered dependent on the child's age, developmental ability, and the concept being measured, and team completion should be considered alongside self-completion and observer measures.

Quality of Life and Its Predictors Among Children and Adolescents With Cancer.

Quality of life (QoL) increasingly is being assessed in pediatric patients with cancer. However, only a few studies focused on QoL predictors during and after treatment for pediatric patients with cancer. The aims of this study were to (1) assess differences of QoL, distress behavior, and fatigue among children and adolescents; (2) examine the relationship of distress behaviors, fatigue, and a variety of demographic factors to QoL; and (3) identify QoL predictors. A cross-sectional descriptive study involving 150 participants treated between 2012 and 2014 was conducted. All participants were given a diagnosis of cancer, ranged in age from 7 to 18 years, and had no developmental delay or mental illness. Three instruments including Pediatric Quality of Life, Distress Behaviors, and Multidimensional Fatigue Scale were administered. Adolescents aged 16 to 18 years reported lower school functioning and experienced more general and sleep/rest fatigue. Fatigue and distress behaviors were associated with a poorer QoL. Diagnosis at a younger age, greater time since diagnosis, and family structure were associated with a better QoL. General fatigue, relationship distress, family structure, and time since diagnosis were significant predictors of QoL, accounting for 64% of the total variance. Factors associated with a poorer QoL included fatigue, distress behaviors, and diagnosis at an older age. Less general fatigue and relationship distress, greater time since diagnosis, and living in nuclear family predicted a better QoL. Routinely evaluating fatigue and school functioning in pediatric patients with cancer is warranted, as well as developing educational programs to enhance the management of fatigue and relationship issues, especially for those who were given a diagnosis recently or for late adolescents.

In the last century, with the advancement of the diagnostic procedures, hematologic disorders in pediatric age group have been increased dramatically. In parallel with this increase, splenectomy procedures have also been popularized with different techniques and surgical outcomes. Laparoscopic splenectomy (LS) in the pediatric age group is generally accepted as a technically demanding procedure, which needs experience. The purpose of this study is to present the long-term follow-up results of a case series of children who underwent LS for a variety of hematologic disorders, evaluate possible complications and outcomes. All patients who were admitted to the clinic and who were scheduled for LS from 2005 to 2016 were considered for this study. The study parameters were grouped in four categories including socio-demographic data, preoperative evaluation, clinical follow-up and complications. There were 24 male (48.9%) and 25 (51.1%) female patients. The median age and body weight for the study group was 12 years and 35 kg. Most common indications for LS were thalassemia (13; 26.5%) and hereditary spherocytosis (12; 24.4%). As a technical standpoint, 2 patients (4%) underwent singleport LS surgery. The mean time for LS surgeries was found as 80 minutes. The total intraoperative complication rate was 4% (2/57). The mean time for hospital stay was 5 days. Mean follow-up period was 6.4 years (range: 6 months-16 years). There was no long-term complication. Bilirubin levels and need for blood transfusion significantly decreased in the long term follow-up period (p <0.05). LS is a powerful tool in the hands of an experienced surgeon. It's a safe and effective procedure in children with hematologic disorders resulting in shorter length of stay and lower complication rates. Sociedad Argentina de Pediatría

Abuse by burning is estimated to occur in 1 to 25% of children admitted with burn injuries annually. Hair and urine toxicology for illicit drug exposure may provide additional confirmatory evidence for abuse. To determine the impact of hair and urine toxicology on the identification of child abuse, we performed a retrospective chart review of all pediatric patients admitted to our burn unit. The medical records of 263 children aged 0 to 16 years of age who were admitted to our burn unit from January 2002 to December 2007 were reviewed. Sixty-five children had suspected abuse. Of those with suspected abuse, 33 were confirmed by the Department of Health and Human Services and comprised the study group. Each of the 33 cases was randomly matched to three pediatric (0-16 years of age) control patients (99). The average annual incidence of abuse in pediatric burn patients was 13.7+/-8.4% of total annual pediatric admissions (range, 0-25.6%). Age younger than 5 years, hot tap water cause, bilateral, and posterior location of injury were significantly associated with nonaccidental burn injury on multivariate analysis. Thirteen (39.4%) abused children had positive ancillary tests. These included four (16%) skeletal surveys positive for fractures and 10 (45%) hair samples positive for drugs of abuse (one patient had a fracture and a positive hair screen). In three (9.1%) patients who were not initially suspected of abuse but later confirmed, positive hair test for illicit drugs was the only indicator of abuse. Nonaccidental injury can be difficult to confirm. Although inconsistent injury history and burn injury pattern remain central to the diagnosis of abuse by burning, hair and urine toxicology offers a further means to facilitate confirmation of abuse.

Adverse drug reactions (ADR) are a public health problem. They cause significant morbidity, mortality and health costs. Less is known about pediatric ADR. Our goal was to characterize a pediatric case series of ADR reported to the Portuguese Pharmacovigilance System (PPS) during the past 10 years. Retrospective analysis of ADR reports concerning patients till 17 years old received by the PPS between 2003 and 2012. We evaluated patients' demographic data and involved drugs, as well as characteristics and seriousness of reactions, stratified by age groups. We found 1742 reports (50% females) corresponding to 9.7% of the total received. The age of the patients varied from 0 to 17 years (median: 5 years, interquartile range: 10.6), with 566 cases (32%) occurring in patients younger than 2y. Among the 1195 serious cases, 31% (370) episodes led to hospitalization. In 32 cases (2%) there was a fatal outcome. Most of the ADR reported referred to general disorders and administration site conditions, followed by skin and subcutaneous tissue reactions. Vaccines were the most represented group (42%) followed by antibacterials for systemic use (17%). Pediatric ADR represents about 10% of the reports received by the PPS. Most ADR were considered serious. Major findings varied according to age groups.

Previous research has identified vaso-occlusive pain crisis as the most common reason for hospitalization among pediatric patients with sickle cell disease. We sought to identify contributors to hospitalization and length of stay (LOS) for this patient population. A descriptive design was used to determine factors associated with hospitalization and LOS for patients with sickle cell disease at an urban tertiary care pediatric hospital in the Midwest. Sickle cell disease as a principal or secondary diagnosis during calendar year 2003 was used to identify patients for study inclusion. Data were collected from subjects' medical records and the hospital accounting system. 72 African American subjects, ranging in age from infant to 24 years (mean = 10.3) met study inclusion criteria, and accounted for 186 hospitalizations. Sickle cell pain crisis was the most common diagnosis associated with hospitalization (n = 122). Adolescent age was significantly associated with longer LOS (r = .451; p<.001), and females stayed on average 2.1 days longer than male subjects (p = .001). Age and gender appear to be associated with LOS in pediatric patients with sickle cell disease, although specific factors underlying these findings remain unclear. Further research is necessary to determine how the complex interplay of social, cultural, developmental, and physiologic factors may contribute to the hospitalization experience of children and adolescents with sickle cell disease.

Summary Radiation therapy is often considered the treatment of choice for low-grade gliomas. However, given the long-term effects of radiation on the developing brain, the appropriate use of radiation therapy in pediatric patients remains controversial. The purpose of this study was to evaluate progression-free survival (PFS) of pediatric low-grade glioma patients treated with radiation therapy. Data were obtained through a retrospective chart review of patients treated between 1991 and 2008 from a single tertiary care center in the midwest. The study population consisted of 17 patients, of whom 8 (47%) had tumor recurrence after radiation therapy. The median follow-up time was 8.2 years, with a range of 2.3 to 17.2 years. The median age at diagnosis was 5.4 years, and the median age at radiation therapy was 9.4 years. The 3- and the 10-year PFS were 69% ± 11.7% and 46% ± 13.3%, respectively. A significant difference in PFS was seen when comparing brainstem tumors with hypothalamic/optic pathway tumors (P = 0.019). Differences in PFS based on the age at diagnosis, the extent of initial surgery, and indication for radiation therapy were not significant. A larger multicenter study is needed to better assess PFS in these patients. PMID:24714505

To evaluate the Symbol Digit Modalities Test (SDMT) as a tool for identifying pediatric-onset MS patients at risk for cognitive impairment. The SDMT is a brief measure of cognitive processing speed that is often used in adult MS patients. Approximately one-third of pediatric-onset MS patients have cognitive impairment and there is a need for an effective screening instrument. Seventy (70) consecutive outpatients with pediatric-onset MS underwent clinical evaluations including the SDMT and were compared to those with other pediatric neurological diagnoses (OND, n=40) and healthy controls (HC, n=32). A subset of the MS group and all healthy controls completed neuropsychological evaluation within one year of SDMT administration. The MS group performed worse on the SDMT compared to the HC group (p=0.02). Thirty-seven percent (37%) of the MS, 20% of the OND, and 9% of HC groups scored in the impaired range. For MS participants who underwent neuropsychological testing (n=31), the SDMT showed 77% sensitivity and 81% specificity for detecting neuropsychological impairment when administered within one year and reached 100% sensitivity when the interval was under two months (n=17). Overall, older age and increased disability predicted poorer SDMT performance (age r=-0.26, p=0.03) and the Expanded Disability Status Scale score or EDSS (r=-0.47, p<0.001), while a history of optic neuritis predicted better performance (p=0.04). Optical coherence tomography measures were not related to SDMT performance. In this preliminary study, the SDMT was an effective brief screen for detecting cognitive impairment in pediatric-onset MS.

Since the use of robotic surgery (RS) revolutionized some adult surgery procedures such as radical prostatectomy, it has been progressively and increasingly introduced in pediatric surgery. The aim of this study is to evaluate how the Da Vinci ® Si HD technology impacts a pediatric public hospital and to define the use of a robotic system in pediatric surgery. We prospectively included patients older than 6 months of age undergoing RS or conventional minimal access surgery (MAS): Study period ranges between February 2015 and April 2016. Surgical indications were defined after a detailed disease-specific diagnostic work-up. We analyzed surgical outcomes and the most relevant economic aspects. The 30-day postoperative complications were evaluated and retrospectively collected in an electronic database. From February 2015 to April 2016, we performed 77 procedures with RS and 84 with conventional MAS in patients with a median age of 77 and 98 months at surgery and a median weight of 20 and 23 kg, respectively. Median operative times were 130 and 109 minutes, respectively. We observed 9.1% of complications in the RS group and 6% in the MAS group and the difference was not statistically significant. Of note, 8 out of 77 RS procedures would have been performed with open classic surgery in case of conversion or failure of RS. This initial experience confirms that RS is as safe and effective as conventional MAS. A number of selected procedures performed with RS would only benefit from this approach, as it is not suitable for conventional MAS. Although economically demanding, in particular for a pediatric hospital, we firmly believe that centralization of care would allow pediatric surgeons adopting RS to perform complex reconstructive surgical procedures with great advantages for the patients and a minimal increase in overall costs for the health system.

OBJECTIVES: Emergence agitation (EA) is a common and troublesome problem in pediatric patients recovering from general anesthesia. The incidence of EA is reportedly higher after general anesthesia maintained with sevoflurane, a popular inhalational anesthetic agent for pediatric patients. We conducted this prospective, randomized, double-blind study to test the effect of an intravenous ultra-short–acting barbiturate, thiamylal, administered during induction of general anesthesia on the incidence and severity of EA in pediatric patients recovering from Sevoflurane anesthesia. METHODS: Fifty-four pediatric patients (1 to 6 years of age) undergoing subumbilical surgeries were randomized into 2 groups. Patients received either intravenous thiamylal 5mg/kg (Group T) or inhalational Sevoflurane 5% (Group S) as an anesthetic induction agent. Following induction, general anesthesia was maintained with Sevoflurane and nitrous oxide (N2O) in both groups. To control the intra- and post-operative pain, caudal block or ilioinguinal/iliohypogastric block was performed. The incidence and severity of EA were evaluated by using the Modified Objective Pain Scale (MOPS: 0 to 6) at 15 and 30 min after arrival in the post-anesthesia care unit (PACU). RESULTS: Fifteen minutes after arrival in the PACU, the incidence of EA in Group T (28%) was significantly lower than in Group S (64%; p = 0.023) and the MOPS in Group T (median 0, range 0 to 6) was significantly lower than in Group S (median 4, range 0 to 6; p = 0.005). The interval from discontinuation of Sevoflurane to emergence from anesthesia was not significantly different between the 2 groups. CONCLUSIONS: Thiamylal induction reduced the incidence and severity of EA in pediatric patients immediately after Sevoflurane anesthesia. PMID:26472953

In 2010, the National Cardiovascular Data Registry enhanced pediatric, nonatherosclerotic structural heart disease and congenital heart disease (CHD) data collection. This report characterizes CHD and pediatric patients undergoing implantable cardioverter defibrillator implantation. In this article, we report implantable cardioverter defibrillator procedures (April 2010 to December 2012) in the registry for 2 cohorts: (1) all patients with CHD (atrial septal defect, ventricular septal defect, tetralogy of Fallot, Ebstein anomaly, transposition of the great vessels, and common ventricle) and (2) patients <21 years. We evaluated indications and characteristics to include transvenous and nontransvenous lead implants, CHD type, and New York Heart Association class. There were 3139 CHD procedures, 1601 for patients <21 years and 126 for CHD <21 years. Implantable cardioverter defibrillator indications for patients with CHD were primary prevention in 1943 (61.9%) and secondary prevention in 1107 (35.2%). Pediatric patients had 935 (58.4%) primary prevention and 588 (36.7%) secondary prevention devices. Primary prevention had higher New York Heart Association class. Nontransvenous age (35.9 ± 23.2 versus 40.1 ± 24.6 years; P=0.05) and nontransvenous height (167.1 ± 18.9 cm; range, 53-193 cm versus 170.4 ± 13.1 cm; range, 61-203 cm; P<0.01) were lower than for transvenous patients. CHD and pediatrics had similar rates of transvenous (97%) and nontransvenous (3%) leads and did not differ from the overall registry. Transposition of the great vessels and common ventricle had higher rates of nontransvenous leads. Primary prevention exceeds secondary prevention for CHD and pediatrics. Nontransvenous lead patients were younger, with higher rates of transposition of the great vessels and common ventricle patients compared with transvenous lead patients. © 2014 American Heart Association, Inc.

Questionnaires are a useful and extensively used tool in clinical sleep medicine and in sleep research. The number of sleep questionnaires targeting the pediatric age range has tremendously increased in recent years, and with such explosion in the number of instruments, their heterogeneity has become all the more apparent. Here, we explore the theoretical and pragmatic processes required for instrument design and development, i.e., how any questionnaire, inventory, log, or diary should be created and evaluated, and also provide illustrative examples to further underline the potential pitfalls that are inherently embedded in every step of tool development.

The authors studied the health-related quality of life of children aged 5 to 18 years with Charcot-Marie-Tooth disease of varying types and severity and compared it with the general pediatric population. To capture and compare the quality-of-life data across a broad range of ages, the Child Health Questionnaire was completed by parents of 127 children with Charcot-Marie-Tooth disease. Affected children exhibited lower physical, psychological, and social well-being than the general pediatric population, with subsequent worsening of many domains with age. The type of Charcot-Marie-Tooth disease influenced some physical and behavioral quality-of-life domains, while gender, body size, and ethnicity did not. Parent characteristics had generally little impact on the reporting of their child's quality of life, although parents with Charcot-Marie-Tooth disease reported higher bodily pain in their children than those without. Overall, quality of life is negatively affected by the presence and severity of Charcot-Marie-Tooth disease in childhood.

Purpose To investigate the frequency of childhood sleep problems at pediatric clinics in Seoul and Gyeonggi provinces. Methods Children (n=936) and their parents who visited 5 primary and 1 secondary pediatric outpatient clinics were invited to complete a Pediatric Sleep Questionnaire. Results Among patients, 901 (96.3%) answered questionnaires in sufficient detail for evaluation. The participant's mean age was 4.35±3.02 years (range, 0–18 years). The male to female ratio was 1:0.93 (466 boys, 435 girls). Habitual snoring (>3 day/week) was reported in 16.9% of the participants. The prevalence of habitual snoring in children <2 years and those between 2–5 years was 9% and 18%, respectively. Sleep disordered breathing was found in 15.1% (106 of 700) of children >2 years. Insomnia was reported in 13.2% of children. The prevalence of sleepwalking, night terrors, and bruxism, is 1.6%, 19%, and 21.1%, respectively. Snoring was associated with increased incidence of sleepwalking, night terrors, and bruxism. Age was associated with insomnia and habitual snoring (P<0.05). Insomnia was more prevalent in younger (21%) than in older children (6%). Snoring was more frequent in both preschool (34%) and school-aged children (33%). The frequency of sleep disordered breathing and insomnia did not vary significantly with gender. However, snoring was more prevalent in boys. Conclusion Sleep problems are frequent among children in Korea. Children with snoring have an increased risk of sleepwalking, night terror, and bruxism. Primary clinicians should consider children's sleep habits to improve their health. PMID:28592979

To determine how training in pediatric cardiopulmonary resuscitation is provided in the Iberoamerican countries. Survey. Latin America, Spain, and Portugal. Experts in pediatric cardiopulmonary resuscitation education. A questionnaire was sent to experts in pediatric cardiopulmonary resuscitation training in 21 countries in Latin America, Spain, and Portugal; we received 15 replies. Pediatric cardiopulmonary resuscitation training is not included in medical undergraduate or nursing training in any of these countries and pediatric residents receive systematic cardiopulmonary resuscitation training in only four countries. Basic pediatric life support courses, pediatric advanced life support courses, and pediatric cardiopulmonary resuscitation instructors courses are given in 13 of 15, 14 of 15, and 11 of 15 respondent countries, respectively. Course duration and the number of hours of practical training were variable: basic life support, 5 hrs (range, 4-8 hrs); practical training, 4 hrs (range, 2-5 hrs); advanced life support, 18 hrs (range, 10-30 hrs); and practical training, 14 hrs (range, 5-18 hrs). Only nine countries (60%) had a national group that organized pediatric cardiopulmonary resuscitation training. Thirteen countries (86.6%) had fewer than five centers offering pediatric cardiopulmonary resuscitation training. Respondents considered the main obstacles to the expansion of training in pediatric cardiopulmonary resuscitation to be the shortage of instructors (28.5%), students' lack of financial resources (21.4%), and deficiencies in educational organization (21.4%). Pediatric cardiopulmonary resuscitation training is not uniform across the majority of Iberoamerican countries, with poor organization and little institutional involvement. National groups should be created in each country to plan and coordinate pediatric cardiopulmonary resuscitation training and to coordinate with other Iberoamerican countries.

Purpose: To investigate the correlation of size-specific dose estimate (SSDE) with absorbed organ dose, and to develop a simple methodology for estimating patient organ dose in a pediatric population (5–55 kg). Methods: Four physical anthropomorphic phantoms representing a range of pediatric body habitus were scanned with metal oxide semiconductor field effect transistor (MOSFET) dosimeters placed at 23 organ locations to determine absolute organ dose. Phantom absolute organ dose was divided by phantom SSDE to determine correlation between organ dose and SSDE. Organ dose correlation factors (CF{sub SSDE}{sup organ}) were then multiplied by patient-specific SSDE to estimate patient organ dose. Themore » CF{sub SSDE}{sup organ} were used to retrospectively estimate individual organ doses from 352 chest and 241 abdominopelvic pediatric CT examinations, where mean patient weight was 22 kg ± 15 (range 5–55 kg), and mean patient age was 6 yrs ± 5 (range 4 months to 23 yrs). Patient organ dose estimates were compared to published pediatric Monte Carlo study results. Results: Phantom effective diameters were matched with patient population effective diameters to within 4 cm; thus, showing appropriate scalability of the phantoms across the entire pediatric population in this study. IndividualCF{sub SSDE}{sup organ} were determined for a total of 23 organs in the chest and abdominopelvic region across nine weight subcategories. For organs fully covered by the scan volume, correlation in the chest (average 1.1; range 0.7–1.4) and abdominopelvic region (average 0.9; range 0.7–1.3) was near unity. For organ/tissue that extended beyond the scan volume (i.e., skin, bone marrow, and bone surface), correlation was determined to be poor (average 0.3; range: 0.1–0.4) for both the chest and abdominopelvic regions, respectively. A means to estimate patient organ dose was demonstrated. Calculated patient organ dose, using patient SSDE and CF{sub SSDE}{sup organ}, was compared to previously published pediatric patient doses that accounted for patient size in their dose calculation, and was found to agree in the chest to better than an average of 5% (27.6/26.2) and in the abdominopelvic region to better than 2% (73.4/75.0). Conclusions: For organs fully covered within the scan volume, the average correlation of SSDE and organ absolute dose was found to be better than ±10%. In addition, this study provides a complete list of organ dose correlation factors (CF{sub SSDE}{sup organ}) for the chest and abdominopelvic regions, and describes a simple methodology to estimate individual pediatric patient organ dose based on patient SSDE.« less

Kawasaki disease shock syndrome (KDSS) and toxic shock syndrome (TSS) can present as shock and fever with skin rash, but the management of these 2 groups of patients is different. This report proposes to help clinicians earlier distinguish these 2 diseases and expedite institution of appropriate therapy. We retrospectively reviewed the medical records of patients admitted to the pediatric intensive care unit with the diagnosis of KDSS or TSS from January 2000 through December 2010. Clinical, laboratory and echocardiographic data were collected for analysis of differences between them. Seventeen patients met the inclusion criteria of KDSS and 16 had a confirmed diagnosis of TSS. The mean age of the KDSS group was significantly younger than that of the TSS group (36.8 ± 41.1 vs. 113.3 ± 55.6 months, P < 0.001). Significantly lower hemoglobulin and age-adjusted hemoglobulin concentrations were noted in the KDSS group [Hb, age-adjusted Z score, -1.88 (range, -3.9 to 3.9) vs. 0.89 (range, -6.4 to 10.8), P = 0.006]. The median platelet count of the KDSS group was nearly twice that of the TSS group [312 × 10³ per μL (range, 116-518) vs. 184.5 × 10³ per μL (range: 31-629), P = 0.021]. Echocardiographic abnormalities, such as valvulitis (mitral or tricuspid regurgitation) and coronary artery lesions, were significantly more common in the KDSS group (P = 0.022). Echocardiography, anemia and thrombocytosis are useful early differentiating features between KDSS and TSS patients.

This study aimed to develop the Scale for Quality of Life in Pediatric Oncology Patients Aged 13-18: Adolescent Form and Parent Form. We used the child and parent information form, Visual Quality of Life Scale, and our own scale, the Scale for Quality of Life in Pediatric Oncology Patients Aged 13-18: Adolescent Form and Parent Form. We finalized the 35-item scale to determine the items, received opinions from 14 specialists on the scale, and pilot-tested the scale in 25 children and their parents. We used Pearson correlation analysis, Cronbach α coefficient, factor analysis and receiver operating characteristics analysis to analyze the data. The total Cronbach α of the parent form was .97, the total factor load was .60-.97 and the total variance was 80.4%. The cutoff point of the parent form was 85.50. The total Cronbach α of the adolescent form was .98, the total factor load was .62-.96, and the total variance explained was 83.4%. The cutoff point of the adolescent form was 75.50. As a result of the parent form factor analysis, we determined the Kaiser-Meyer-Olkin coefficient as .83, the Barlett test χ(2) as 12,615.92; the factor coefficients of all items of the parent form ranged from .63 to .98. The factor coefficients of all items of the adolescent form ranged from .34 to .99. As a result of the adolescent form factor analysis, we determined the KMO as .79, and the Barlett test χ(2) as 13,970.62. Conclusively, we found that the adolescent form and the parent form were valid and reliable in assessing the children's quality of life. Copyright © 2016. Published by Elsevier B.V.

The clinical and epidemiologic characteristics of pediatric sporotrichosis are poorly understood. To describe the incidence and clinical characteristics of cases of sporotrichosis in children 14 years of age and younger reported in Abancay from 2004 to 2011, stratified according to age. We performed a retrospective review of pediatric patients 14 years of age and younger who were diagnosed with sporotrichosis in a referral center at Abancay, a poor area located in the south central highlands of Peru, to estimate the incidence rates (per 100,000 person-years) according to age and sporotrichosis type (lymphocutaneous and fixed), and clinical characteristics of these patients. Of the 240 pediatric cases identified, 131 (54.6%) were male. The median age at baseline was 6 years. The mean incidence rate was 81.4 cases per 100,000 person-years for the period from 2004 to 2011, and was highest among children ranging in age from 5-9 years. The incidence of lymphocutaneous sporotrichosis and fixed sporotrichosis was 55 and 27 cases per 100,000 person-years, respectively, and the face was the most commonly affected anatomic site. Ninety-six of the 240 patients (40%) reported previous contact with cats, and 46 (19.2%) had a clear history of traumatic inoculation with plant material. The therapeutic response to treatment with potassium iodide was satisfactory. In this retrospective study, we described a high incidence of sporotrichosis in children in the south central highlands of Peru, which increased with age. Lymphocutaneous sporotrichosis was the more common type with an incidence rate twice that of the fixed type. The face was the most commonly affected anatomic site, and infection appeared to be acquired predominantly through contact with cats. © 2017 The International Society of Dermatology.

This paper describes FitKids360, a stage 2 pediatric weight management program. FitKids360 is a physician-referred, multicomponent, low-cost healthy lifestyle program for overweight and obese youth 5-16 years of age and their families. FitKids360 provides an evidence-based approach to the treatment of pediatric overweight by targeting patients' physical activity, screen time, and dietary behaviors using a family-centered approach. The intervention begins with a two-hour orientation and assessment period followed by six weekly sessions. Assessments include lifestyle behaviors, anthropometry, and the Family Nutrition and Physical Activity (FNPA) survey, which screens for obesogenic risk factors in the home environment. Outcomes are presented from 258 patients who completed one of 33 FitKids360 classes. After completing FitKids360, patients increased moderate to vigorous physical activity by 14 minutes (P = 0.019), reduced screen time by 44 minutes (P < 0.001), and improved key dietary behaviors. Overall, FNPA scores increased by 9% (P < 0.001) and 69% of patients with "high risk" FNPA scores at baseline dropped below the "high risk" range by followup. Patients also lowered BMIs (P = 0.011) and age- and sex-adjusted BMI z-scores (P < 0.001) after completing the 7-week program. We hope this report will be useful to medical and public health professionals seeking to develop stage 2 pediatric obesity programs.

Severe pediatric facial trauma is characterized by multiple, comminuted, and unstable fractures, frequently necessitating operative intervention. Disruption of facial growth is a primary concern in the long-term sequelae of such conditions. Children suffering from midface fractures were followed over time in a long-term growth and development study. Lateral cephalograms at longest-term follow-up were traced, digitized, and averaged. Seven landmarks of the midface (A point, ANS, orbitale, bridge of nose, distal U6, upper lip, stomion superius) were identified for comparative measurements with age and sex-matched superimposed Bolton norms as controls. Differences in x and y axes between test and control metrics were measured. Clinical significance was defined as a 2-mm discrepancy from the norm. Statistical significance for each patient was determined using t tests of the x and y arrays of patient values versus normal controls. Seven patients met the inclusion criteria with mean age of 8.9 years at the time of injury. Mean cephalometric follow-up was 4.6 years (range 2-10 years). Six out of 7 patients (86%) showed clinically significant impairment in growth in horizontal (29%), vertical (29%), or both planes (29%). T Tests confirmed statistical significance (P ≤ 0.05) for all clinically significant differences. Mean deficiency in growth for all landmarks was 3.7  mm (range -4.0 to 13.7  mm) in the x axis and 2.9  mm (range -1.1 to 8.8  mm) in the y axis. Severe pediatric midface trauma often results in compromised bone growth and permanent facial deformity. New methodologies of management that better allow for growth are needed.

Context: Bilateral pediatric cataracts are important cause of visual impairment in children. Aim: To study the outcome of bilateral pediatric cataract surgery in young children. Setting and Design: Retrospective case series in a tertiary center. Materials and Methods: Records of pediatric cataracts operated between January 2001 and December 2003, with a minimum follow-up of 3 months, were reviewed retrospectively. Statistical Methods: Independent sample t-test, Fisher's exact test, and logistic regression using SPSS (Statistical Package for Social Science, Chicago, USA) version 12. Results: 215/257 (83.7%) patients had a minimum follow-up of 3 months. The mean age of presentation to the hospital was 53 months (range: 0-168 months). Congenital cataract was present in 107 patients (58.2%) and developmental cataract in 77 patients (41.8%). The mean age at surgery was 55.2 months (range: 1-168 months). Out of 430 eyes, 269 (62.6%) had an intraocular lens implanted. The mean duration of follow-up was 13.1 months (range: 3-38 months). Pre-operatively, 102 patients (47.3%) had visual acuity <6/60, in the better eye, compared to 37 patients (17.2%) post-operatively (P < 0.001). Eighty-five patients (39.5%) had visual acuity >6/18. The most common early post-operative complication was fibrinous uveitis in 57 eyes (13.3%) and the most common delayed post-operative complication was posterior capsular opacification in 118 eyes (27.4%). The most important prognostic factor for poor outcome was congenital cataract (odds ratio [OR]: 26.3; 95% confidence interval [CI], 4.4-158.5) and total cataract (OR: 4.8; 95% CI, 1.3-17).

Multiple treatment modalities exist for unicameral bone cysts (UBC), including steroid injection, autologous bone marrow injection, mechanical decompression, intramedullary fixation, curettage, and bone grafting. All have their own potential limitations such as high recurrence rates, cyst persistence, need for multiple procedures, and prolonged immobilization. A minimally invasive regimen consisting of curettage, decompression, and injection of a calcium sulfate-calcium phosphate (CaSO4-CaPO4) composite has been utilized at our institution in an attempt to obtain optimal results for the treatment of UBCs in the pediatric population. We retrospectively evaluated 16 patients with pathologically confirmed UBC who were treated with curettage, decompression, and injection of a calcium sulfate-calcium phosphate composite between April 2006 and August 2010 at a single institution. The average age of the patients at time of surgical intervention was 9.4 years of age (range, 3 to 16 y). Average follow-up was 16 months (range, 6 to 36 mo). Radiographic healing, clinical outcomes, and complications were evaluated. Final follow-up radiographs demonstrated healing in 93.7% (15 of 16) of patients after a single procedure. Complete healing was observed in 14 of 16 patients and partially healed with a defect in 1 of 16 patients. One patient had a persistent cyst but did not wish to receive further treatment. All patients returned to full activities including sports on average at 3.1 months (range, 1 to 6 mo) and were asymptomatic on most recent follow-up. No postoperative complications, including refracture, were observed. Curettage, decompression, and injection of a calcium sulfate-calcium phosphate composite for UBC in the pediatric population demonstrates encouraging results with low recurrence rates and complications compared with conventional methods.

Quality-of-life (QOL) measures can be a valuable tool to assess the general welfare across a spectrum of patients in a pediatric orthopaedic outpatient clinic and can be a simple way to assess patient-based outcomes particularly for quality initiatives. The Pediatric Outcomes Data Collection Instrument (PODCI) is validated for many orthopaedic conditions but typically takes around 20 minutes to complete (86 questions). The Pediatric Quality of Life Inventory (PedsQL) takes <4 minutes to complete (23 questions) but has not been assessed in an orthopaedic setting. We initiated this study to find the best method for assessing QOL in our outpatient clinic. A short pediatric QOL measure that is correlated to an established orthopaedic-specific QOL measure is needed; therefore, we compared the PedsQL to the PODCI in the outpatient orthopaedic clinic. This was a quality initiative project and as such did not require a priori IRB approval. Families of patients 2 to 18 years old who presented for follow-up after upper or lower extremity fractures or brachial plexus injuries in the orthopaedic clinic from October 2010 through August 2011 were asked to fill out both the PODCI and the PedsQL. Patients aged 5 years and older filled out a patient-report PedsQL; patients aged 11 years and older filled out the patient-report PODCI. Parents/guardians completed questionnaires for children of all ages. Most fracture patients (and/or their parent/guardian) repeated the questionnaires after 6 to 12 weeks. Data were then assessed for correlation between the PODCI and PedsQL. A total of 428 parent/guardian reports for 283 patients and 172 self-reports for 104 patients were included. The correlation between the PODCI Global score and the PedsQL Total score for the parent/guardian-reported questionnaires for all injuries was 0.77 (95% confidence interval, 0.72-0.82). When categorized within domains and injuries, parent/guardian-reported correlations ranged from 0.23 to 0.79. In patients aged 11 years and older, the correlation between the PODCI and PedsQL for the patient-reported questionnaire for all injuries was 0.85 (95% confidence interval, 0.80-0.89). When categorized within domains and injuries, patient-reported correlations ranged from 0.30 to 0.99. Utilizing the substantially shorter PedsQL in a high volume orthopaedic clinic as a substitute for the PODCI for quality improvement measures seems reasonable. Correlation between the PedsQL Global score and the PODCI Total score for orthopaedic patients is strong. Utilizing the patient-reported questionnaires when age appropriate is best. In this era of increased outcome reporting, PedsQL may be a valuable tool.

In 1993, the nonbenzodiazepine sedative-hypnotic zolpidem tartrate (Ambien) was approved for use in the US. Zolpidem has an imidazopyridine structure and possesses a rapid onset of action and a short half-life. The toxic threshold and profile have not been well established in the pediatric population. All pediatric zolpidem exposures reported to a regional poison information center over 24 months were reviewed retrospectively from the American Association of Poison Control Centers Toxic Exposure Surveillance System data collection forms. Twelve pediatric zolpidem exposures were reported. Seven were unintentional (ages 20 mon-5 y) and five were intentional misuse/suicide (ages 12-16 y). The regional poison information center was contacted within 1 h in ten cases with onset of symptoms within 10 to 60 min (mean 31.6 min). One child had no effect with 2.5 mg. As little as 5 mg caused symptoms with minor outcome in six unintentional ingestions (5-30 mg). Minor to moderate symptoms were reported 1-4 h after intentional ingestions (12.5-150 mg). The duration of symptoms in the unintentional cases ranged from less than 60 min up to 4 h (mean 2.4 h) and 6-10 h (mean 7.5 h) in the intentional exposures. Treatment consisted of observation (4), syrup of ipecac (1), lavage and activated charcoal (1), activated charcoal alone (5), and unknown (1). Due to the very rapid onset of central nervous system symptoms in children, emesis is not a treatment option. Supportive care, activated charcoal in large ingestions, and observation until symptoms resolve may be sufficient in most pediatric cases.

To investigate: 1) the demographics and clinical characteristics, 2) the findings, and 3) the safety and effectiveness in a cohort of Chinese pediatric patients undergoing colonoscopy. The study participants were consecutive patients aged ≤14 years old that underwent their first colonoscopy in the endoscopy center at the First Affiliated Hospital, Sun Yat-sen University between Jan. 1, 2001 and Dec. 31, 2012. Demographic, clinical, endoscopic, and pathological findings were collected. The cohort consisted of 322 patients, including 218 boys (67.7%) and 104 girls (32.3%). The median age was 8.0 years old and ranged from 9 months to 14 years old. Hematochezia (48.8%) and abdominal pain/discomfort (41.3%) were the most common presentations preceding pediatric colonoscopy. The caecal intubation success rate was 96.3%. No serious complications occurred during the procedures. A total of 227 patients (70.5%) received a positive diagnosis under endoscopy, including 138 patients with polyps and 53 patients with inflammatory bowel disease (IBD). Among the patients with polyps, 71.0% were juvenile polyps. Comparisons between years 2001-2006 and 2007-2012 showed that the IBD detection rate increased significantly (4.6% vs. 22.4%, P<0.001), while the opposite occurred for the polyp detection rate (73.1% vs. 27.6%, P<0.001). Colonoscopy in pediatric patients is a safe and effective procedure. Polyps are the primary finding during colonoscopy. In South China there has been an increase in pediatric patients diagnosed with IBD over the past decade. However, a large epidemiological study is needed to confirm our findings.

To analyze the nutritional status of pediatric patients after orthotopic liver transplantation and the relationship with short-term clinical outcome. Anthropometric evaluations of 60 children and adolescents after orthotopic liver transplantation, during the first 24 hours in a tertiary pediatric intensive care unit. Nutritional status was determined from the Z score for the following indices: weight/age height/age or length/age, weight/height or weight/length, body mass index/age, arm circumference/age and triceps skinfold/age. The severity of liver disease was evaluated using one of the two models which was adequated to the patients' age: 1. Pediatric End-stage Liver Disease, 2. Model for End-Stage Liver Disease. We found 50.0% undernutrition by height/age; 27.3% by weight/age; 11.1% by weight/height or weight/ length; 10.0% by body mass index/age; 61.6% by arm circumference/age and 51.0% by triceps skinfold/age. There was no correlation between nutritional status and Pediatric End-stage Liver Disease or mortality. We found a negative correlation between arm circumference/age and length of hospitalization. Children with chronic liver diseases experience a significant degree of undernutrition, which makes nutritional support an important aspect of therapy. Despite the difficulties in assessment, anthropometric evaluation of the upper limbs is useful to evaluate nutritional status of children before or after liver transplantation.

Objective To describe the qualitative development of the Patient-Reported Outcome Measurement Information System (PROMIS®) Pediatric Stress Response item banks. Methods Stress response concepts were specified through a literature review and interviews with content experts, children, and parents. A library comprising 2,677 items derived from 71 instruments was developed. Items were classified into conceptual categories; new items were written and redundant items were removed. Items were then revised based on cognitive interviews (n = 39 children), readability analyses, and translatability reviews. Results 2 pediatric Stress Response sub-domains were identified: somatic experiences (43 items) and psychological experiences (64 items). Final item pools cover the full range of children’s stress experiences. Items are comprehensible among children aged ≥8 years and ready for translation. Conclusions Child- and parent-report versions of the item banks assess children’s somatic and psychological states when demands tax their adaptive capabilities.

Rates and characteristics of intracerebral cavernous malformations (ICMs) after cranial radiation therapy (CRT) remain poorly understood. Herein we report on ICMs detected on follow+up imaging in pediatric cancer patients who received CRT at age ≤ 18 years from 1980 to 2009. Through chart reviews (n=362) and phone interviews (n=104) of a retrospective cohort we identified 10 patients with ICMs. The median latency time for detection of ICMs after CRT was 12 years (range 1+24 years) at a median age of 21.4 years (IQR 15+28). The cumulative incidence was 3% (95% CI 1+8%) at 10 years post CRT and 14% (95% CI 7+26%) at 15 years. Three patients underwent surgical resection. Two surgical specimens were pathologically similar to sporadically occurring ICMs; one was consistent with capillary telangiectasia. ICMs are common after CRT and can show a spectrum of histological features. PMID:25122111

Narcolepsy, a chronic disorder of the sleep–wake cycle of multifactorial etiology, is characterized by excessive daytime sleepiness, often associated with cataplexy, hypnagogic/hypnopompic hallucinations and sleep paralysis. Both early clinical suspicion and therapeutic approach are essential for promotion of cognitive development and social integration of these children. The authors present a descriptive retrospective study of a series of eight children in whom symptoms first started between 6.8 and 10.5 years of age. Diagnostic delay ranged from 4 months to 2 years. One child had H1N1 flu vaccination eight months before the clinical onset. The first multiple sleep latency test was positive in 6 of 8 cases. All cases were treated with methylphenidate, and venlafaxine was associated in 4 of them. In one case the initial therapy was exclusively behavioral. In all cases, symptomatic improvement, better school performance and social integration were achieved after therapeutic adjustment. PMID:26483902

Background and Objectives: For reduced port surgery in pediatric patients, the initial umbilical incision plays an important role in both functional ability and cosmetic impact. Larger umbilical incisions enable better manipulation of forceps, extraction of larger surgical specimens, and easier exteriorization of the intestine for anastomosis. We have pursued an incision of the small pediatric umbilicus that allows for enlargement of the orifice of the abdominal opening with preservation of the natural umbilical profile. This article aims to present a new umbilical incision technique and describe the outcomes. Methods: We devised a new umbilical incision technique for reduced port surgery in pediatric patients. Our incision is made in an inverted Y shape (Benz incision), allowing for access port device insertion. The Benz incision technique was applied between November 2010 and May 2014 and was retrospectively studied. Results: Seventy-five patients underwent Benz incisions. The median age of all patients was 6 years 6 months (range, 26 days to 18 years), and the median body weight was 21.7 kg (range, 3.1–54.3 kg). Benz incisions were applied for various procedures, including reduced port surgery with hepaticojejunostomy for congenital biliary dilatation, portojejunostomy for biliary atresia, Meckel diverticulectomy, tumor resection, varicocelectomy, cholecystectomy, splenectomy, ileus surgery, ileocecal resection, and total colectomy. All patients were successfully treated, without a significant increase in operating time or severe complications. The cosmetic profile of the umbilicus was maintained after surgery. Conclusion: The Benz incision is a feasible, effective, and scarless approach for reduced port surgery in pediatric patients whose umbilical rings are too small for the conventional approach.

To document the quantity and architecture of sleep using objective electrophysiologic assessment in sedated mechanically ventilated pediatric intensive care unit patients over a 24-hr period and to investigate the effect of noise and staff interventions on sleep pattern in these subjects. Prospective observational study. Pediatric intensive care unit at a university hospital. A total of 11 patients studied between September 2000 and June 2001, with ages ranging from 3 to 21 months. All patients were intubated, mechanically ventilated, and sedated with morphine and midazolam infusions. Limited sleep polysomnograph, staff interventions, and noise levels were continuously monitored during a 24-hr period. Noise levels were consistently >48 dB(A); the highest night peak reached 103 dB(A). Staff interventions lasted for a mean of 240 (SD 90) mins in a 24-hr period. There was no significant difference in the number of interventions between day and night. Severe alterations to sleep architecture were found throughout the 24 hrs, with no diurnal variations. Active sleep was severely reduced to a mean of 3% (SD 4%; range, 0-11%) of total sleep time. There was severe sleep fragmentation as reflected by the high number (mean, 40 [SD 20]) of wake episodes. The above findings suggest a significant electrophysiologic abnormality of sleep in the pediatric intensive care unit patients. Our pediatric intensive care unit environment is characterized by both, high noise levels and frequent staff interventions. This study has several limitations and future studies are needed, with larger sample size and an attempt to manipulate the environmental factors to minimize their negative effects on sleep.

Risk of multiple sclerosis (MS) is influenced by environment and genetics. Infant breastfeeding appears protective against some childhood autoimmune disorders, but its impact on risk of MS in childhood is unknown. The objective of this study is to analyze the association of breastfeeding in infancy on future risk of pediatric-onset MS. Biological mothers of 36 consecutive pediatric-onset MS patients completed a questionnaire on history of breastfeeding and various birth and demographic factors. The control group consisted of 72 otherwise healthy patients with a diagnosis of migraine and normal brain magnetic resonance imaging obtained less than 12 months before enrollment. Inverse probability of treatment weighting was used to reduce selection bias and balance the covariates between breastfed and non-breastfed children. Demographics (with the exception of body mass index) and birth factors were not significantly different between groups. Whereas 36% of cases were breastfed, 71% of controls were breastfed (P = 0.001). The median duration of breastfeeding was 0 weeks (range: 0 to 40 weeks) for cases and 16 weeks (range: 0 to 216 weeks) for controls. Lack of infant breastfeeding was associated with future diagnosis of pediatric-onset MS (odds ratio = 4.43; 95% confidence interval, 1.68 to 11.71; P = 0.003). This association remained significant after correcting for covariates, such as body mass index and age at diagnosis. These data demonstrate that absence of infant breastfeeding has an association with an increased risk of pediatric-onset MS diagnosis. Copyright © 2017 Elsevier Inc. All rights reserved.

Delivery of inhaled drugs for infants and small children: a commentary on present and future needs.

PubMed

Fink, James B

2012-11-01

Although the manufacture of inhaled medications is a multibillion dollar industry, virtually no pharmaceutical drug/device combination has been approved for inhalation across the range of pediatric patient ages and sizes. The clinician who treats neonates, infants, or toddlers is often faced with the dilemma of prescribing inhaled medications that may be disease appropriate but have not been approved for use in patients in these age categories. Their use is thus technically "off label," with limited empirical data to guide both dose and device selection. This dilemma requires the prescribing physician to go beyond the limitations of the product label, often without benefit of appropriately designed clinical trials, in an attempt to select safe and effective doses for use with these smallest of patients. The vast majority of drugs approved for inhalation were studied by using aerosol devices designed for older children and adults using a mouthpiece interface, which may not be practical for use in infants and patients aged <4 years. The selection of the most age-appropriate device and interface is critical for the effective administration of the prescribed therapy. In the absence of industry-sponsored clinical trials in neonates, infants, and toddlers, in vitro and in vivo strategies may help guide age-appropriate dosing, device, and interface selection to better inform clinical practice. In this commentary, the challenges in developing and prescribing effective formulations for aerosol delivery across the range of pediatric ages and sizes are explored, with guidance for device and interface selection. Recommendations for future collaborative sharing of in vitro models and age-specific breathing patterns between academic and industry researchers could help regulators and clinicians better understand the impact age and size have on pulmonary drug delivery.

Age related changes in fractional elimination pathways for drugs: assessing the impact of variable ontogeny on metabolic drug-drug interactions.

The magnitude of any metabolic drug-drug interactions (DDIs) depends on fractional importance of inhibited pathway which may not necessarily be the same in young children when compared to adults. The ontogeny pattern of cytochrome P450 (CYP) enzymes (CYPs 1A2, 2B6, 2C8, 2C9, 2C18/19, 2D6, 2E1, 3A4) and renal function were analyzed systematically. Bootstrap methodology was used to account for variability, and to define the age range over which statistical differences existed between each pair of specific pathways. A number of DDIs were simulated (Simcyp Pediatric v12) for virtual compounds to highlight effects of age on fractional elimination and consequent magnitude of DDI. For a theoretical drug metabolized 50% by each of CYP2D6 and CYP3A4 pathways at birth, co-administration of ketoconazole (3 mg/kg) resulted in a 1.65-fold difference between inhibited versus uninhibited AUC compared to 2.4-fold in 1 year olds and 3.2-fold in adults. Conversely, neonates could be more sensitive to DDI than adults in certain scenarios. Thus, extrapolation from adult data may not be applicable across all pediatric age groups. The use of pediatric physiologically based pharmacokinetic (p-PBPK) models may offer an interim solution to uncovering potential periods of vulnerability to DDI where there are no existing clinical data derived from children. © The Author(s) 2013.

Mortality Risk in Pediatric Motor Vehicle Crash Occupants: Accounting for Developmental Stage and Challenging Abbreviated Injury Scale Metrics.

Survival risk ratios (SRRs) and their probabilistic counterpart, mortality risk ratios (MRRs), have been shown to be at odds with Abbreviated Injury Scale (AIS) severity scores for particular injuries in adults. SRRs have been validated for pediatrics but have not been studied within the context of pediatric age stratifications. We hypothesized that children with similar motor vehicle crash (MVC) injuries may have different mortality risks (MR) based upon developmental stage and that these MRs may not correlate with AIS severity. The NASS-CDS 2000-2011 was used to define the top 95% most common AIS 2+ injuries among MVC occupants in 4 age groups: 0-4, 5-9, 10-14, and 15-18 years. Next, the National Trauma Databank 2002-2011 was used to calculate the MR (proportion of those dying with an injury to those sustaining the injury) and the co-injury-adjusted MR (MRMAIS) for each injury within 6 age groups: 0-4, 5-9, 10-14, 15-18, 0-18, and 19+ years. MR differences were evaluated between age groups aggregately, between age groups based upon anatomic injury patterns and between age groups on an individual injury level using nonparametric Wilcoxon tests and chi-square or Fisher's exact tests as appropriate. Correlation between AIS and MR within each age group was also evaluated. MR and MRMAIS distributions of the most common AIS 2+ injuries were right skewed. Aggregate MR of these most common injuries varied between the age groups, with 5- to 9-year-old and 10- to 14-year-old children having the lowest MRs and 0- to 4-year-old and 15- to 18-year-old children and adults having the highest MRs (all P <.05). Head and thoracic injuries imparted the greatest mortality risk in all age groups with median MRMAIS ranging from 0 to 6% and 0 to 4.5%, respectively. Injuries to particular body regions also varied with respect to MR based upon age. For example, thoracic injuries in adults had significantly higher MRMAIS than such injuries among 5- to 9-year-olds and 10- to 14-year-olds (P =.04; P <.01). Furthermore, though AIS was positively correlated with MR within each age group, less correlation was seen for children than for adults. Large MR variations were seen within each AIS grade, with some lower AIS severity injuries demonstrating greater MRs than higher AIS severity injuries. As an example, MRMAIS in 0- to 18-year-olds was 0.4% for an AIS 3 radius fracture versus 1.4% for an AIS 2 vault fracture. Trauma severity metrics are important for outcome prediction models and can be used in pediatric triage algorithms and other injury research. Trauma severity may vary for similar injuries based upon developmental stage, and this difference should be reflected in severity metrics. The MR-based data-driven determination of injury severity in pediatric occupants of different age cohorts provides a supplement or an alternative to AIS severity classification for pediatric occupants in MVCs.

The specific aim of this study was to evaluate the feasibility, reproducibility and maturational changes of LV rotation, twist and torsion variables by real-time 3D speckle-tracking echocardiography (RT3DSTE) in children. A prospective study was conducted in 347 consecutive healthy subjects (181 males/156 females, mean age 7.12 ± 5.3 years, and range from birth to 18-years) using RT 3D echocardiography (3DE). The LV rotation, twist and torsion measurements were made off-line using TomTec software. Manual landmark selection and endocardial border editing were performed in 3 planes (apical "2"-, "4"-, and "3"- chamber views) and semi-automated tracking yielded LV rotation, twist and torsion measurements. LV rotation, twist and torsion analysis by RT 3DSTE were feasible in 307 out of 347 subjects (88.5%). There was no correlation between rotation or twist and age, height, weight, BSA or heart rate, respectively. However, there was statistically significant, but very modest correlation between LV torsion and age (R2 = 0.036, P< 0.001). The normal ranges were defined for rotation and twist in this cohort, and for torsion for each age group. The intra-observer and inter-observer variabilities for apical and basal rotation, twist and torsion ranged from 7.3% ± 3.8% to 12.3% ± 8.8% and from 8.8% ± 4.6% to 15.7% ± 10.1%, respectively. We conclude that analysis of LV rotation, twist and torsion by this new RT3D STE is feasible and reproducible in pediatric population. There is no maturational change in rotation and twist, but torsion decreases with age in this cohort. Further refinement is warranted to validate the utility of this new methodology in more sensitive and quantitative evaluation of congenital and acquired heart diseases in children.

To define the sex prevalence of inpatient hospital discharges for pediatric patients diagnosed with upper urinary tract stone disease. The study examined inpatient admissions for pediatric urolithiasis in 2003, using the Healthcare Cost and Utilization Project Kids' Inpatient Database. We used the International Classification of Disease, 9th edition, Clinical Modification codes, to identify patients with a principal diagnosis of renal (592.0) or ureteral (592.1) calculi. Sex prevalence was assessed, and the results were stratified by age group. In the 2003 Kids' Inpatient Database, the sex distribution among pediatric patients with stone formation varied significantly by age. In the first decade of age, a male predominance was found that had shifted to a female predominance in the second decade. Overall, however, girls in the pediatric population were more commonly affected by stones than were boys. In this nationally representative sample, the sex distribution of pediatric urolithiasis varied with age, with boys more commonly affected in the first decade of age and girls in the second decade. Although the reason for this unique epidemiologic finding is not readily apparent, additional studies can build on this hypothesis-generating work.

The health care team. The role of pediatric nurse practitioners as viewed by California pediatricians.

A single-mailing questionnaire surveyed attitudes of members of District IX, American Academy of Pediatrics (California) toward the role of the pediatric nurse practitioner (pnp). Responses from 568 members (53%) represented a broad range of age, practice type (58% group, 25% solo, 17% "other"), geographic location, and opinion. The most favorable attitudes toward pnp use were expressed by young pediatricians in large-group and "other" categories; least favorable were solo practitioners older than 60 years. Practice type was more important than age. Most respondents expressed the opinion that a pediatrician-pnp team approach would enrich both professions, and that parental acceptance of the pnp was likely; but that pnp use would not reduce costs. Majorities favored the concept of the pnp as part of the practice team but under constant pediatrician surveillance: seeing the patient for part of the visit and participating under supervision in care for minor illness, but not replacing the pediatrician even in well-child care. Some pnps hope for a more independent role on the pediatrician-pnp team. Modification of both pediatrician and pnp ideas appears requisite to a team approach that will satisfy both professional groups and the public.

Competent examination of the pediatric musculoskeletal (MSK) system is a vital component of clinical assessment of children with MSK presentations. The aim was to develop a regional MSK examination for school-age children that is age appropriate and reflects clinical practice. Qualitative and quantitative analyses involving video observation of clinical examination technique, systematic review, and expert consensus were employed to reveal descriptions, frequencies, and variations in technique for joint regions in various clinical scenarios. Systematic review and data from clinical observation were combined with feedback from a group of pediatric MSK experts through a web-based survey. All results were collated and discussed by consensus development groups to derive the pediatric Regional Examination of the Musculoskeletal System (pREMS). A total of 48 pediatric MSK expert clinicians were involved to derive pREMS. Systematic review revealed a paucity of evidence about regional pediatric MSK examination. Video observations of MSK examinations (a total of 2,901 maneuvers) performed by pediatric MSK experts (n = 11 doctors and 8 therapists) of 89 school-age children attending outpatient clinics in 7 UK pediatric rheumatology centers were followed by semistructured interviews with 14 of 19 clinicians. Video observation showed variation in examination techniques, most frequently at the hip and knee in the context of mechanical and inflammatory clinical scenarios. pREMS is the first practice- and consensus-based regional pediatric MSK examination for school-age children. The structured approach is an important step toward improved pediatric MSK clinical skills relevant to clinical training. Copyright © 2011 by the American College of Rheumatology.

Introduction: Tumors of the central nervous system (CNS) are the second most frequent malignancy of childhood and the most common solid tumor in this age group. CNS tumors represent approximately 17% of all malignancies in the pediatric age range, including adolescents. Glial neoplasms in children account for up to 60% of supratentorial intraaxial tumors. Their histological distribution and prognostic features differ from that of adults. Aims and Objectives: To study clinical and pathological characteristics, and to analyze the outcome using the Engel's classification for seizures, Karnofsky's score during the available follow-up period of minimum 1 year following the surgical and adjuvant therapy of supratentorial intraaxial extraventricular primary pediatric (SIEPP) brain tumors in children equal or less than 18 years. Materials and Methods: The study design is a prospective study done in NIMS from October 2008 to January 2012. All the patients less than 18 years of age operated for SIEPP brain tumors proven histopathologically were included in the study. All the patients with recurrent or residual primary tumors or secondaries were excluded from the study. Post operative CT or magnetic resonance imaging (MRI) is done following surgery. Results and Analysis: There were 2, 8 and 20 patients in the age range of 0-2 years, >2-10 years and 10-18 years, respectively. There were 21 male patients and 9 female patients. Out of 30 patients, 16 had lesion in the temporal lobe, 6 in frontal lobe, 4 in thalamus, 3 in parietal lobe and 1 in occipital lobe. Out of 30 patients, 11 patients had malignant lesions and nineteen patients had benign lesions. Gross total excision could be achieved in 19 patients and subtotal in 11 patients. Seven patients had mortality and four of the remaining 23 patients had increased deficits postoperatively. Remaining 19 patients either improved or remained same. Conclusions: SIEPP brain tumors have male preponderance, occur in 95% of patients in the age range of 7-18 years and have temporal lobe as the most common site of origin. The seizure presentation has good outcome compared to raised intracranial pressure features. The seizure control is quite good irrespective of subtotal or gross total excision in temporal lobe low grade tumors. All PNETs have survival of less than 1 year even with adjuvant chemo and radiotherapy. PMID:25624922

IMPORTANCE Acute kidney injury (AKI) after pediatric cardiac surgery is associated with high short-term morbidity and mortality; however, the long-term kidney outcomes are unclear. OBJECTIVE To assess long-term kidney outcomes after pediatric cardiac surgery and to determine if perioperative AKI is associated with worse long-term kidney outcomes. DESIGN, SETTING, AND PARTICIPANTS This prospective multicenter cohort study recruited children between ages 1 month to 18 years who underwent cardiopulmonary bypass for cardiac surgery and survived hospitalization from 3 North American pediatric centers between July 2007 and December 2009. Children were followed up with telephone calls and an in-person visit at 5 years after their surgery. EXPOSURES Acute kidney injury defined as a postoperative serum creatinine rise from preoperative baseline by 50% or 0.3 mg/dL or more during hospitalization for cardiac surgery. MAIN OUTCOMES AND MEASURES Hypertension (blood pressure ≥95th percentile for height, age, sex, or self-reported hypertension), microalbuminuria (urine albumin to creatinine ratio >30 mg/g), and chronic kidney disease (serum creatinine estimated glomerular filtration rate [eGFR] <90 mL/min/1.73 m2 or microalbuminuria). RESULTS Overall, 131 children (median [interquartile range] age, 7.7 [5.9–9.9] years) participated in the 5-year in-person follow-up visit; 68 children (52%) were male. Fifty-seven of 131 children (44%) had postoperative AKI. At follow-up, 22 children (17%) had hypertension (10 times higher than the published general pediatric population prevalence), while 9 (8%), 13 (13%), and 1 (1%) had microalbuminuria, an eGFR less than 90 mL/min/1.73 m2, and an eGFR less than 60 mL/min/1.73 m2, respectively. Twenty-one children (18%) had chronic kidney disease. Only 5 children (4%) had been seen by a nephrologist during follow-up. There was no significant difference in renal outcomes between children with and without postoperative AKI. CONCLUSIONS AND RELEVANCE Chronic kidney disease and hypertension are common 5 years after pediatric cardiac surgery. Perioperative AKI is not associated with these complications. Longer follow-up is needed to ascertain resolution or worsening of chronic kidney disease and hypertension. PMID:27618162

We describe the use of ustekinumab for 4 patients with pediatric Crohn disease treated at the Seattle Children's Hospital Inflammatory Bowel Disease Center. A retrospective chart review was done to identify patients' clinical data, disease phenotype, treatment history, and laboratory and growth parameters before treatment with ustekinumab and at last follow-up. Adverse events while on ustekinumab were also recorded. Four adolescent patients with Crohn disease at our center received ustekinumab. All had previously received corticosteroids, methotrexate, azathioprine/6-mercaptopurine, and both infliximab and adalimumab. Patients had varying disease phenotypes. Ages at ustekinumab initiation were 12, 13, 16, and 17 years. Weight ranged from 40.5 to 57.8 kg, mean 49.5 kg. Two patients showed clinical response and remain on ustekinumab. Two patients discontinued therapy because of continued symptoms and disease complications and required multiple hospitalizations. Ustekinumab was used in 4 children with pediatric Crohn disease with 2 of 4 patients showing clinical response (1 with persistently elevated C-reactive protein). A prospective study is needed to define its efficacy, safety, and placement in managing pediatric Crohn disease in the future.

Few data exist on resource utilization with pediatric ventricular assist devices (VADs). We tested the hypothesis that device type and adverse events are associated with increased resource utilization in pediatric patients supported with VADs. The Pediatric Interagency Registry for Mechanically Assisted Circulatory Support, a national registry of VADs in patients <19 years old, and the Pediatric Health Information System, an administrative database, were merged. Univariate analysis was performed assessing the association of all factors with the total cost and length of stay first. Significant variables ( P <0.05) were subjected to multivariable analysis. The study included 142 patients from 19 centers with VAD implants from October 2012 to June 2016. The median age was 9 years (interquartile range [IQR] 2-15), 84 (59%) supported with a continuous-flow VAD. Overall median hospital costs were $750 000 (IQR $539 000 to $1 100 000) with a median hospital length of stay of 81 days (IQR 54-128). On multivariable analysis, device type and postoperative complications were not associated with resource utilization. Factors associated with increased costs included patient age, lower-volume VAD center, being intubated, being on extracorporeal membrane oxygenation, number of complex chronic medical conditions, and length of stay. Among continuous-flow VAD patients, discharge to home before transplant versus remaining hospitalized was associated with lower hospital costs (median $600 000 [IQR $400 000 to $820 000] versus median $680 000 [IQR $500 000 to $970 000], P =0.03). VADs in pediatric patients are associated with high resource utilization. Increased resource utilization was associated with lower-volume VAD centers, disease severity at VAD implantation, and the presence of complex chronic medical conditions. Further study is needed to develop cost-effective strategies in this complex population. © 2018 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley.

We aimed to apply the pediatric abdominal CT protocol of Donnelly et al. in the United States to the pediatric abdominal CT-AEC. Examining CT images of 100 children, we found that the sectional area of the hepatic portal region (y) was strongly correlated with the body weight (x) as follows: y=7.14x + 84.39 (correlation coefficient=0.9574). We scanned an elliptical cone phantom that simulates the human body using a pediatric abdominal CT scanning method of Donnelly et al. in, and measured SD values. We further scanned the same phantom under the settings for adult CT-AEC scan and obtained the relationship between the sectional areas (y) and the SD values. Using these results, we obtained the following preset noise factors for CT-AEC at each body weight range: 6.90 at 4.5-8.9 kg, 8.40 at 9.0-17.9 kg, 8.68 at 18.0-26.9 kg, 9.89 at 27.0-35.9 kg, 12.22 at 36.0-45.0 kg, 13.52 at 45.1-70.0 kg, 15.29 at more than 70 kg. From the relation between age, weight and the distance of liver and tuber ischiadicum of 500 children, we obtained the CTDI vol values and DLP values under the scanning protocol of Donnelly et al. Almost all of DRL from these values turned out to be smaller than the DRL data of IAEA and various countries. Thus, by setting the maximum current values of CT-AEC to be the Donnelly et al.'s age-wise current values, and using our weight-wise noise factors, we think we can perform pediatric abdominal CT-AEC scans that are consistent with the same radiation safety and the image quality as those proposed by Donnelly et al.

Single-center studies have failed to link modest increases in total donor ischemic time to mortality after pediatric orthotopic heart transplant. We aimed to investigate whether prolonged total donor ischemic time is linked to pediatric intensive care morbidity after orthotopic heart transplant. Retrospective cohort review. Tertiary pediatric transplant center in the United Kingdom. Ninety-three pediatric orthotopic heart transplants between 2002 and 2006. Total donor ischemic time was investigated for association with early post-orthotopic heart transplant hemodynamics and intensive care unit morbidities. Of 43 males and 50 females with median age 7.2 (interquartile range 2.2, 13.0) yrs, 62 (68%) had dilated cardiomyopathy, 20 (22%) had congenital heart disease, and nine (10%) had restrictive cardiomyopathy. The mean total donor ischemic time was 225.9 (sd 65.6) mins. In the first 24 hrs after orthotopic heart transplant, age-adjusted mean arterial blood pressure increased (p < .001), mean pulmonary arterial pressure fell (p = .012), but central venous pressure (p = .58) and left atrial pressure (p = .20) were unchanged. After adjustment for age, primary diagnosis, pre-orthotopic heart transplant mechanical support, and marginal donor factors, longer total donor ischemic time was significantly associated with lower mean arterial blood pressure (p < .001) in the first 24 hrs after orthotopic heart transplant, longer post-orthotopic heart transplant mechanical ventilation (p = .03), longer post-orthotopic heart transplant stay in the intensive care unit (p = .004), and longer post-orthotopic heart transplant stay in hospital (p = .02). Total donor ischemic time was not related to levels of mean pulmonary arterial pressure (p = .62), left atrial pressure (p = .38), or central venous pressure (p = .76) early after orthotopic heart transplant. Prolonged total donor ischemic time has an adverse effect on the donor organ, contributing to lower mean arterial blood pressure, as well as more prolonged ventilation and intensive care unit and hospital stays post-orthotopic heart transplant, reflecting increased morbidity.

Age of cases: median, five months and controls, one year (p=0.02). Median weight, 7 vs. 10 kg (p=0.634). Surgical interventions: median n=2 (range, 1-8) vs. n=1 (range, 1-7). Infection rate, 13.2%. Main etiology ductal stenosis, n=29 (29%) vs. n=50 (23%) (p=0.530). Non-communicating, n=50 (51%) vs. 396 (61%) (p=0.456). Predominant microorganisms: enterobacteria, pseudomonas, and enterococcus. Non-use of iodized dressing OR=2.6 (range, 1.8-4.3), use of connector OR=6.8 (range, 1.9-24.0), System replacement OR=2.0 (range, 1.3-3.1), assistant without surgical facemask OR=9.7 (range, 2.3-42.0). Being a breastfeeding infant, of low weight, non-application of iodized dressing, use of connector, previous derivation, and lack of adherence to aseptic technique were all factors associated with ependymitis.

Alemtuzumab (Campath-1H) is a monoclonal antibody directed against CD52-positive B and T lymphocytes. Initial results of its use as an induction agent in adult renal transplantation have been encouraging. We report a case series of four low-risk pediatric renal transplantation patients who received 20 to 40 mg of alemtuzumab as induction followed by a steroid-free regimen consisting of a calcineurin inhibitor and mycophenolate mofetil. No infusion-related reactions occurred. Patients were aged 9 to 14 years with a mean creatinine of 1.2 mg/dL (range = 0.5-2.3 mg/dL) at a mean follow-up of 10 months (range = 4-16 months). One patient experienced biopsy-proven acute cellular rejections at 4 and 12 months posttransplantation, which were steroid sensitive. Lymphopenia post-alemtuzumab induction started to improve at 3 months posttransplantation. Two patients who received 40 mg of alemtuzumab experienced repeated infections that responded to 7-day courses of antibiotics. There was no cytomegalovirus disease detected. From these preliminary results, alemtuzumab seems to show a promising role to achieve adequate graft function with a steroid-free regimen among low-risk pediatric patients.

We investigated early outcomes for patients receiving chemotherapy followed by consolidative proton therapy (PT) for the treatment of Hodgkin lymphoma (HL). From June 2008 through August 2015, 138 patients with HL enrolled on either IRB-approved outcomes tracking protocols or registry studies received consolidative PT. Patients were excluded due to relapsed or refractory disease. Involved-site radiotherapy field designs were used for all patients. Pediatric patients received a median dose of 21 Gy(RBE) [range 15-36 Gy(RBE)]; adult patients received a median dose of 30.6 Gy(RBE) [range, 20-45 Gy(RBE)]. Patients receiving PT were young (median age, 20 years; range 6-57). Overall, 42% were pediatric (≤18 years) and 93% were under the age of 40 years. Thirty-eight percent of patients were male and 62% female. Stage distribution included 73% with I/II and 27% with III/IV disease. Patients predominantly had mediastinal involvement (96%) and bulky disease (57%), whereas 37% had B symptoms. The median follow-up was 32 months (range, 5-92 months). The 3-year relapse-free survival rate was 92% for all patients; it was 96% for adults and 87% for pediatric patients (P = 0.18). When evaluated by positron emission tomography/computed tomography scan response at the end of chemotherapy, patients with a partial response had worse 3-year progression-free survival compared with other patients (78% versus 94%; P = 0.0034). No grade 3 radiation-related toxicities have occurred to date. Consolidative PT following standard chemotherapy in HL is primarily used in young patients with mediastinal and bulky disease. Early relapse-free survival rates are similar to those reported with photon radiation treatment, and no early grade 3 toxicities have been observed. Continued follow-up to assess late effects is critical. © The Author 2017. Published by Oxford University Press on behalf of the European Society for Medical Oncology.

The content validity of the 28-item PedsQL™ 3.0 Diabetes Module has not been established in research on pediatric and adult patients with newly diagnosed Type 1 diabetes across a broad age range. This study aimed to document the content validity of three age-specific versions (8-12 years, 13-18 years, and 18-45 years) of the PedsQL™ Diabetes Module in a population of newly diagnosed patients with Type 1 diabetes. The study included in-depth interviews with 31 newly diagnosed patients with Type 1 diabetes between the ages of 8 and 45 years, as well as 14 parents and/or caregivers of child and teenage patients between the ages of 8 and 18 years of age; grounded theory data collection and analysis methods; and review by clinical and measurement experts. Following the initial round of interviews, revisions reflecting patient feedback were made to the Child and Teen versions of the Diabetes Module, and an Adult version of the Diabetes Module was drafted. Cognitive interviews of the modified versions of the Diabetes Module were conducted with an additional sample of 11 patients. The results of these interviews support the content validity of the modified 33-item PedsQL™ 3.2 Diabetes Module for pediatric and adult patients, including interpretability, comprehensiveness, and relevance suitable for all patients with Type 1 Diabetes. Qualitative methods support the content validity of the modified PedsQL™ 3.2 Diabetes Module in pediatric and adult patients. It is recommended that the PedsQL™ 3.2 Diabetes Module replaces version 3.0 and is suitable for measuring patient-reported outcomes in all patients with newly diagnosed, stable, or long-standing diabetes in clinical research and practice.

Objective: To analyze the current status of epidemiological study of burns in China, and to explore the related strategies. Methods: Retrospective or cross-sectional scientific articles in Chinese or English on epidemiological study of burns in China published from January 2005 to December 2015 were systemically retrieved from 4 databases. The databases include PubMed, Embase, China Biology Medicine disc, and Chinese Journals Full - text Database . From the results retrieved, data with regard to publication year, journal distribution, number of institutions participated in the study, affiliation of the first author and its location, and admission time span and age of patients in all the scientific articles were collected. Furthermore, the definition of age range and the grouping method of age of pediatric patients in English articles on epidemiological study of pediatric burns of China were recorded. Data were processed with descriptive statistical analysis. Results: A total of 256 scientific articles conforming to the study criteria were retrieved, among which 214 (83.59%) articles were in Chinese, and 42 (16.41%) articles were in English; 242 (94.53%) articles were retrospective studies, and 14 (5.47%) articles were cross-sectional studies. During the 11 years, the number of the relevant articles was fluctuant on the whole. The scientific articles were published in 130 journals, with 42 English articles in source journals for SCIENCE CITATION INDEX EXPANDED - JOURNAL LIST, accounting for 16.41%, and 116 Chinese articles in Source Journal for Chinese Scientific and Technical Papers, accounting for 45.31%. Totally 215 (83.98%) articles were single-center studies, and 29 (11.33%) articles were multicenter studies which were conducted by three or more centers. The number of affiliations of the first author of articles was 161 in total. The top 10 institutions regarding the article publishing number published 58 articles, accounting for 22.66%. Scientific articles on epidemiological study of burns were retrieved with location of affiliation of the first author in 31 provinces, autonomous regions, and municipalities directly under the Central Government in Mainland China, and also in Taiwan Province and Hong Kong Special Administrative Region, among which Shanghai ranked first with 24 (9.38%) articles published. The admission time span of patients in the articles ranged from 3 months to 47 years, with 120 (46.87%) articles from 3 months to 5 years, 79 (30.86%) articles from 6 to 10 years, and 57 (22.27%) articles more than 10 years, respectively. Regarding the age of patients in the study, 123 articles were on epidemiological study of pediatric burns, and 16 articles on epidemiological study of elderly burns, accounting for 48.05% and 6.25%, respectively. Further analysis of articles on epidemiological study of pediatric burns in English showed that there was no standard definition of age range or unified grouping method of age for pediatric burn patients. Conclusions: The epidemiological study of burns in China has been carried out nationwide, but the number of institutions conducted relevant study is not that much, and multicenter epidemiological studies remain scanty. The quality of the articles needs to be further improved. The epidemiological study of elderly burns is relatively deficient and calls for more attention. The epidemiological study of burns in China lacks regularity or continuity in time scope. There is an urgent need for the guideline on classification method for items of epidemiological study of burns in China so as to standardize the related research.

This review was an effort to systematically examine the nationwide data available on pediatric burns requiring hospitalization to reveal burn epidemiology and guide future education and prevention. The China Biomedical Disk Database, Chongqing VIP Database, and China Journal Full-Text Database were searched for articles reporting data on children and their burns from January 2000 through December 2005. Studies were included that systematically investigated the epidemiology of pediatric burns requiring hospitalization in China. Twenty-eight articles met the inclusion criteria, all of which were retrospective analyses. For each study included, 2 investigators independently abstracted the data related to the population description by using a standard form and included the percentage of patients with burn injury who were <15 years old; gender and distribution of age; type of residential area; place of injury; distribution of months and time; reasons for burn; anatomical sites of burn; severity of burn; and mortality and cause of death. These data were extracted, and a retrospective statistical description was performed with SPSS11.0 (SPSS Inc, Chicago, IL). Of the pediatric patients studied, the proportion of children with burn injury ranged from 22.50% to 54.66%, and the male/female ratio ranged from 1.25:1 to 4.42:1. The ratio of children aged 3 years was 0.19:1 to 4.18:1. The rural/urban ratio was 1.60:1 to 12.94:1. The ratio of those who were burned indoors versus outdoors was 1.62 to 17.00, and there were no effective hints on the distribution of seasons and anatomical sites of burn that could be found. The peak hours of pediatric burn were between 17:00 and 20:00. Most articles reported the sequence of reasons as hot liquid > flame > electricity > chemical, and scalding was, by far, the most predominant reason for burn. The majority of the studies reported the highest proportion involved in moderate burn, and the lowest proportion was for critical burn. The mortality rate ranged from 0.49% to 9.08%, and infection, shock, and multiple organ dysfunction syndrome were the most common causes of death. Considering the national proportion of children, a high proportion of hospitalized patients with burn injury were children; those who were male, aged

Qualitative research is pivotal in gaining understanding of individuals' experiences in pediatric palliative care. In the past few decades, the number of qualitative studies on pediatric palliative care has increased slightly, as has interest in qualitative research in this area. Nonetheless, a limited number of such studies have included the first-person perspective of children. The aim of this article is to understand the contribution of previous qualitative research on pediatric palliative care that included the voices of children. A systematic review of qualitative studies and a meta-summary were conducted. MEDLINE, CINAHL, PsycINFO, PsycARTICLES, and ERIC were searched without limitations on publication date or language. Eligible articles were qualitative research articles in which the participants were children ranging in age from 3 to 18 years.ResultWe retrieved 16 qualitative research articles reporting on 12 unique studies, and we selected two mixed-method articles. The meta-summary shows eight themes: the relationship with professional caregivers, pain and its management, "living beyond pain," the relationship between pediatric patients and their families, children's view on their treatment and service provision, meanings children give to their end-of-life situation, consequences of clinical decisions, and the relationships among children in pediatric palliative care and their peers.Significance of resultsThis meta-summary presents the "state of the art" of pediatric palliative care qualitative research on children and highlights additional research areas that warrant qualitative study.

Is pediatric IBD treatment different than in adults?

2012-06-01

The incidence of pediatric inflammatory bowel disease (IBD) continues to rise in most countries. Approximately 20-25% of IBD patients present before the age of 20, and their management is associated with many unique challenges. These challenges stem both from the inherent differences between children and adults, and from the differences in the nature and course of the disease. Children with IBD are more likely than adults to present with extensive disease ‑ both in Crohn's disease (CD) and ulcerative colitis (UC). Diagnosis requires a high index of suspicion, as children may present with less typical signs such as poor growth and delayed puberty. In the very young patients with inflammatory bowel disease, the pediatric clinician must consider a broader range of immunological and allergic disorders. Optimal management requires recognition of pediatric patterns of presentation, efficacy and adverse-effect profiles, and understanding monitoring aspects unique to pediatrics. These aspects include pediatric disease-related psychological issues, adherence to therapy and transition to adult care. Inadequate attention to growth, puberty or bone health in childhood can result in long-term consequences, such as impaired adult height and increased risk of fractures. Management of pediatric IBD and prevention of adverse long-term consequences relies on a variety of therapies well-known to the adult practitioner, along with therapies that are not widespread in adults, most notably exclusive enteral nutrition (EEN). The latter is as effective as corticosteroids in achieving clinical remission in children, while achieving better results than corticosteroids with regard to mucosal healing and growth. This review discusses the broad variety of issues that form the basis for management of pediatric IBD.

Background Health related quality of life (HRQL) assessments during therapy for pediatric cancer are important. The objective of this study was to describe reasons for failure to provide HRQL assessments during a pediatric acute myeloid leukemia (AML) clinical trial. Methods We focused on HRQL assessments embedded in a multicenter pediatric AML clinical trial. The PedsQL 4.0 Generic Core Scales, PedsQL 3.0 Acute Cancer Module, PedsQL Multidimensional Fatigue Scale, and Pediatric Inventory for Parents were obtained from parent/guardian respondents at a maximum of six time points. Children provided self-report optionally. A central study coordinator contacted sites with delinquent HRQL data. Reasons for failure to submit the HRQL assessments were evaluated by three pediatric oncologists and themes were generated using thematic analysis. Results There were 906 completed and 1091 potential assessments included in this analysis (83%). The median age of included children was 12.9 years (range 2.0 to 18.9). The five themes for non-completion were: patient too ill; passive or active refusal by respondent; developmental delay; logistical challenges; and poor knowledge of study processes from both the respondent and institutional perspective. Conclusions We identified reasons for non-completion of HRQL assessments during active therapy. This information will facilitate recommendations to improve study processes and future HRQL study designs to maximize response rates. PMID:24040278

This study examined the pharmacokinetics of sirolimus in pediatric allogeneic blood and marrow transplantation (BMT) recipients in the presence and absence of concomitant fluconazole. Forty pediatric BMT recipients received a daily oral dose of sirolimus and a continuous i.v. infusion of tacrolimus for graft-versus-host disease prophylaxis. Fluconazole was administered i.v. to 19 patients and orally to 6 patients. Full pharmacokinetic profiles of sirolimus within a single dosing interval were collected. Whole-blood sirolimus concentrations were measured by HPLC/mass spectrometry. Noncompartmental analysis was performed using WinNonlin. Nonlinear mixed-effects pharmacokinetic models were developed using NONMEM following standard procedures. The mean ± SD sirolimus trough level before the dose (C0) was 8.0 ± 4.6 ng/mL (range, 1.8–21.6 ng/mL). The peak concentration was 19.9 ± 11.8 ng/mL (range, 3.9–46.1 ng/mL), and the trough level 24 hours later (C24) was 9.1 ± 5.3 ng/mL (range, 1.0–19.1 ng/mL). The terminal disposition half-life (T1/2) was 24.5 ± 11.2 hours (range, 5.8–53.2 hours), and the area under the concentration-versus-time curve (AUC0–24) was 401.1 ± 316.3 ng·h/mL (range, 20.7–1332.3 ng·h/mL). In patients at steady state, C0 and C24 were closely correlated (R2 = 0.77) with a slope of 0.99, indicating the achievement of steady state. C24 was 1.7-fold greater (P = .036) and AUC0–24 was 2-fold greater (P = .012) in Caucasian patients (n = 22) compared with Hispanic patients (n = 9). The average apparent oral clearance was 3-fold greater (P = .001) and the apparent oral volume of distribution was 2-fold greater (P = .018) in patients age ≤12 years compared with those age >12 years. C24 was significantly lower in patients (n = 10) who developed grade III–IV aGVHD (n = 10) than in those with grade 0-II aGVHD (n = 22) (6.1 ± 2.9 ng/mL versus 9.4 ± 5.5 ng/mL; P = .044). Dose-normalized sirolimus trough concentrations were significantly higher in patients receiving concomitant fluconazole therapy compared with those not receiving fluconazole (C0: 3.9 ± 2.5 versus 2.4 ± 1.5 ng/mL/mg, P = .030; C24: 4.8 ± 3.3 versus 2.5 ± 1.7 ng/mL/mg, P = .018). This pharmacokinetic study of sirolimus in pediatric patients documents a large interindividual variability in the exposure of sirolimus. Steady-state trough blood concentrations were correlated with drug exposure. Trough concentrations were higher with a concomitant use of fluconazole and were higher in Caucasian patients than in Hispanic patients. Oral clearance was greater in children age ≤12 years than in older children and adolescents. With therapeutic drug monitoring, the majority (79%) of sirolimus trough levels could be maintained within the target range (3–12 ng/mL). This study provides a rationale and support for dose adjustments of sirolimus based on steady-state blood concentrations aimed at achieving a target concentration to minimize toxicity and maximize therapeutic benefits in pediatric BMT recipients.

The purposes of this study were to provide national estimates of emergency department (ED) visits for medical device-associated adverse events (MDAEs) in the pediatric population and to characterize these events further. ED medical record reports from the National Electronic Injury Surveillance System All Injury Program database from January 1, 2004, through December 21, 2005, were reviewed. MDAEs among pediatric patients were identified, and data were abstracted. National estimates for pediatric MDAEs were determined according to medical specialty, device category and class, injury diagnosis, and patient characteristics and outcome. The total estimated number of pediatric MDAEs during the 24-month period was 144,799 (95% confidence interval: 113,051-183,903), involving devices from 13 medical specialties. Contact lenses accounted for most MDAEs (23%), followed by hypodermic needles (8%). The distribution of MDAEs according to medical specialty varied according to age subgroup. The most-prevalent types of injuries included contusions/abrasions, foreign-body intrusions, punctures, lacerations, and infections. The most-frequently affected body parts were the eyeball, pubic region, finger, face, and ear. The majority of pediatric MDAEs involved class II (moderate-risk) devices. The incidence of pediatric MDAEs decreased with increasing age from early to late childhood and then spiked after 10 years of age. More girls than boys were affected at older ages (16-21 years) and more boys than girls at younger ages (< or =10 years). Hospitalizations were more likely to involve invasive or implanted devices. This study provides national estimates of pediatric MDAEs resulting in ED visits and highlights the need to develop interventions to prevent pediatric device-related injuries.

Phenytoin is a commonly used antiepileptic medication in the pediatric age group, but it has a narrow therapeutic range. Various adverse effects have been reported commonly. We report a relatively rare case of encephalopathy in a child from overdose of injectable phenytoin due to ignorance of the previous treatment. Scrutiny of medical records and history is of utmost importance while administering such medications.

2012-01-01

Magnetic resonance imaging of pediatric brain provides valuable information for early brain development studies. Automated brain extraction is challenging due to the small brain size and dynamic change of tissue contrast in the developing brains. In this paper, we propose a novel Learning Algorithm for Brain Extraction and Labeling (LABEL) specially for the pediatric MR brain images. The idea is to perform multiple complementary brain extractions on a given testing image by using a meta-algorithm, including BET and BSE, where the parameters of each run of the meta-algorithm are effectively learned from the training data. Also, the representative subjects are selected as exemplars and used to guide brain extraction of new subjects in different age groups. We further develop a level-set based fusion method to combine multiple brain extractions together with a closed smooth surface for obtaining the final extraction. The proposed method has been extensively evaluated in subjects of three representative age groups, such as neonate (less than 2 months), infant (1–2 years), and child (5–18 years). Experimental results show that, with 45 subjects for training (15 neonates, 15 infant, and 15 children), the proposed method can produce more accurate brain extraction results on 246 testing subjects (75 neonates, 126 infants, and 45 children), i.e., at average Jaccard Index of 0.953, compared to those by BET (0.918), BSE (0.902), ROBEX (0.901), GCUT (0.856), and other fusion methods such as Majority Voting (0.919) and STAPLE (0.941). Along with the largely-improved computational efficiency, the proposed method demonstrates its ability of automated brain extraction for pediatric MR images in a large age range. PMID:22634859

A recent task force has proposed the use of Sequential Organ Failure Assessment in clinical criteria for sepsis in adults. We sought to evaluate the predictive validity for PICU mortality of the Pediatric Logistic Organ Dysfunction-2 and of the "quick" Pediatric Logistic Organ Dysfunction-2 scores on day 1 in children with suspected infection. Secondary analysis of the database used for the development and validation of the Pediatric Logistic Organ Dysfunction-2. Nine university-affiliated PICUs in Europe. Only children with hypotension-low systolic blood pressure or low mean blood pressure using age-adapted cutoffs-and lactatemia greater than 2 mmol/L were considered in shock. We developed the quick Pediatric Logistic Organ Dysfunction-2 score on day 1 including tachycardia, hypotension, and altered mentation (Glasgow < 11): one point for each variable (range, 0-3). Outcome was mortality at PICU discharge. Discrimination (Area under receiver operating characteristic curve-95% CI) and calibration (goodness of fit test) of the scores were studied. This study included 862 children with suspected infection (median age: 12.3 mo; mortality: n = 60 [7.0%]). Area under the curve of the Pediatric Logistic Organ Dysfunction-2 score on day 1 was 0.91 (0.86-0.96) in children with suspected infection, 0.88 (0.79-0.96) in those with low systolic blood pressure and hyperlactatemia, and 0.91 (0.85-0.97) in those with low mean blood pressure and hyperlactatemia; calibration p value was 0.03, 0.36, and 0.49, respectively. A Pediatric Logistic Organ Dysfunction-2 score on day 1 greater than or equal to 8 reflected an overall risk of mortality greater than or equal to 9.3% in children with suspected infection. Area under the curve of the quick Pediatric Logistic Organ Dysfunction-2 score on day 1 was 0.82 (0.76-0.87) with systolic blood pressure or mean blood pressure; calibration p value was 0.89 and 0.72, respectively. A score greater than or equal to 2 reflected a mortality risk greater than or equal to 19.8% with systolic blood pressure and greater than or equal to 15.9% with mean blood pressure. Among children admitted to PICU with suspected infection, Pediatric Logistic Organ Dysfunction-2 score on day 1 was highly predictive of PICU mortality suggesting its use to standardize definitions and diagnostic criteria of pediatric sepsis. Further studies are needed to determine the usefulness of the quick Pediatric Logistic Organ Dysfunction-2 score on day 1 outside of the PICU.

The aim of this study was to analyze insulin-like growth factor I (IGF-I) serum level in pediatric patients with cancer compared with pediatric patients with nononcological diseases and to assess the relationship between IGF-I and nutritional status of oncological patients. From January 2009 to July 2012, we assessed 151 consecutively hospitalized patients in a tertiary emergency pediatric hospital. The patients were divided into two groups: group I, consisting of patients with malignant diseases (64 patients), and group II, the control group, consisting of 87 age- and gender-matched patients with different pediatric diseases. The anthropometric parameters (weight, height, body mass index, middle upper arm circumference (MUAC), and tricipital skinfold thickness (TST) and biochemical parameters (proteins, albumin, and total IGF-I) were comparatively evaluated at the diagnosis and after intensive chemotherapy in the malignant group. Anthropometric and biochemical parameters in group I were significantly different from those in group II for height, MUAC, TST, total proteins, and albumin (p < 0.05). Twenty-five out of 64 patients with malignant diseases and 5 out of 87 patients in the control group had malnutrition. IGF-I in patients with cancer was much lower than in the control group (median 48.3 ng/ml, range 25.00-662.00 ng/ml vs 129.00 ng/ml, range 25.00-745.00 ng/ml) (p = 0.014). We found a positive correlation between IGF-I, MUAC, and TST at the diagnosis of the malignant disease. Also, we identified positive correlations between IGF-I, protein, and albumin. Serum IGF-I levels in cancer patients were significantly lower at diagnosis than after chemotherapy (48.3 ng/ml, range 25.00-662.00 ng/ml vs 110.0 ng/ml, range 25.00-573.00 ng/ml; p = 0.04). IGF-I seems to be an accurate biochemical parameter used in malnutrition assessment of children with cancer. IGF-I correlated with the anthropometric parameters of the arm, serum protein, and albumin. These parameters most accurately characterize the nutritional status.

Development of optimized pediatric formulations for oral administration can be challenging, time consuming, and financially intensive process. Since its inception, the biopharmaceutical classification system (BCS) has facilitated the development of oral drug formulations destined for adults. At least theoretically, the BCS principles are applied also to pediatrics. A comprehensive age-appropriate BCS has not been fully developed. The objective of this work was to provisionally classify oral drugs listed on the latest World Health Organization's Essential Medicines List for Children into an age-appropriate BCS. A total of 38 orally administered drugs were included in this classification. Dose numbers were calculated using age-appropriate initial gastric volume for neonates, 6-month-old infants, and children aging 1 year through adulthood. Using age-appropriate initial gastric volume and British National Formulary age-specific dosing recommendations in the calculation of dose numbers, the solubility classes shifted from low to high in pediatric subpopulations of 12 years and older for amoxicillin, 5 years, 12 years and older for cephalexin, 9 years and older for chloramphenicol, 3-4 years, 9-11 and 15 years and older for diazepam, 18 years and older (adult) for doxycycline and erythromycin, 8 years and older for phenobarbital, 10 years and older for prednisolone, and 15 years and older for trimethoprim. Pediatric biopharmaceutics are not fully understood where several knowledge gaps have been recently emphasized. The current biowaiver criteria are not suitable for safe application in all pediatric populations.

This study aims to review surgical outcomes of pediatric patients undergoing total pancreatectomy with islet cell autotransplantation (TP/IAT) for the treatment of chronic pancreatitis (CP). All pediatric patients (≤18 years old) undergoing TP/IAT over a 10-year period (December 2002-June 2012) were identified for inclusion in a single-center, observational cohort study. Retrospective chart review was performed to identify pertinent preoperative, perioperative, and postoperative data, including narcotic usage, insulin requirements, etiology of pancreatitis, previous operative interventions, operative times, islet cell yields, duration of hospital stay, and overall quality of life. Quality of life was assessed using the Short Form-36 health questionnaire. Fourteen pediatric patients underwent TP/IAT for the treatment of CP at the University of Cincinnati with a mean age of 15.9 years (range, 14-18) and a mean body mass index of 21.8 kg/m(2) (range, 14-37). Of the patients, 50% (n = 7) were male and 29% had undergone previous pancreatic operations (1 each of Whipple, Puestow, Frey, and Berne procedures). Etiology of pancreatitis was idiopathic for 57% (n = 8); the remainder had identified genetic mutations predisposing to pancreatitis (CFTR, n = 4; SPINK1, n = 1; PRSS1, n = 1). Mean operative time was 532 minutes (range, 360-674) with an average hospital duration of stay of 16 days (range, 7-37). Islet cell isolation resulted in mean islet cell equivalents (IEQ) of 500,443 in patients without previous pancreatic surgery versus 413,671 IEQ in patients with prior pancreatic surgery (P = .12). Median patient follow-up was 9 months from surgery (range, 1-78). Preoperatively, patients required on average 32.7 morphine equivalent mg per day (MEQ), which improved to 13.9 MEQ at most recent follow-up. Eleven patients (79%) were narcotic independent. None of the patients were diabetic preoperatively. All of the patients were discharged after the operation with scheduled insulin requirements (mean, 17 U/d). This requirement decreased to a mean of 10.1 U/d at most recent follow-up visit. Four patients (29%) progressed to insulin independence. All patients in this series achieved stable glycemic control postoperatively and there was no incidence of "brittle" diabetes. Quality-of-life surveys showed improvement in all tested modules. This study represents one of the largest series examining TP/IAT in the pediatric population. Pediatric patients benefitted from TP/IAT with a decrease in postoperative narcotic requirements, stable glycemic control, and improved quality of life. Copyright © 2013 Mosby, Inc.

Facial fractures are relatively uncommon in the pediatric population, especially those inflicted as a result of interpersonal violence in the form of gunshot injuries. Few studies have examined the unique management of such high-energy injuries in the pediatric population. Oftentimes the resultant damage to soft tissue and bony structures is so great that it challenges the previously accepted standards in the management of pediatric facial fractures. This study will examine a level 1 trauma center's experience with these unique injuries. A retrospective review of all facial fractures occurring in a pediatric population (those 18 years of age or younger) as a result of gunshot wounds in a level 1 trauma center in an urban environment was performed for the years 2000 to 2012. Descriptive information was collected regarding each case as well as information regarding concomitant injuries, treatment modalities, and selected outcomes. During this time period, there were 3147 facial fractures treated at our institution, 353 of which were in pediatric patients. Of these, 17 were the results of gunshot wounds. Three patients were excluded due to insufficient data, leaving a total of 14 patients. The average age of patients was 16.5 (range 14-18); all patients were African-American males. The most common fracture was that of the mandible (n = 10), with 2 of those patients exhibiting panfacial fractures. The average Glasgow Coma Scale on admission was 13.5 (range 3-15). Six of the patients were intubated in the emergency department. The most common concomitant injury was a skull fracture (n = 3), followed by cervical spine fractures (n = 2) and intracranial hemorrhages (n = 2). All patients were admitted to the hospital for reasons other than fracture management. Seven patients ultimately went to the operating room for fracture management. The treatment modalities employed were conservative management with closed techniques (n = 11), rigid internal fixation (n = 2), and the use of an external fixator device (n = 1). Minimal to no soft-tissue debridement was performed in 10 of the 14 patients, 2 of which presented between 6 months and 10 years post-injury with soft-tissue complications related to retained material. The mean hospital length of stay was 8.2 days (range 1-18 days). One patient expired. Pediatric facial fractures as a result of gunshot wounds represent a unique and fortunately rare entity that presents a challenge to all disciplines involved in treatment. In our patients, there was a tendency towards conservative management, with only 3 patients undergoing some form of fixation and only 7 undergoing some form of operative debridement. Concomitant injuries and the high-energy nature of gunshot wounds often preclude traditional management with rigid fixation to ensure adequate bony healing. However, it is important to adequately debride devitalized soft tissue and remove all foreign material to avoid future soft tissue-related complications.

Many children are not being properly restrained in motor vehicles, resulting in unnecessary injury and fatalities. Health care provider (HCP) education is effective at increasing proper child restraint within vehicles. However, differences exist by HCP specialty in regards to frequency of child passenger safety (CPS) counseling. This study of a sample of 255 HCPs examined differences in CPS counseling by HCP specialty (pediatric vs. non-pediatric). HCPs from several upper Midwest states were surveyed about how frequently they provide CPS counseling in their practice by patient age and their attitudes toward CPS-related issues. Pediatric HCPs were twice as likely as non-pediatric HCPs to always provide CPS counseling to parents/guardians of children aged 5 or older. Non-pediatric HCPs were more likely than pediatric HCPs to feel that counseling is ineffective at increasing child seat/booster (p = 0.001) or seat belt use (p = 0.006). Non-pediatric HCPs were more likely than pediatric HCPs to feel there is inadequate time to provide CPS counseling in their practice setting (p = 0.001), and were less likely to know where to refer patients if they have questions regarding CPS issues (0.0291). The differences in HCP attitudes toward CPS counseling provision and the resulting differences in counseling frequency by patient age may contribute to disparities for patients who have limited or no access to pediatric HCPs. Additional research is needed to investigate the rationale for counseling differences seen by HCP specialty and patient age, and the potential effect on child motor vehicle injuries and fatalities.

Experimental Injury Biomechanics of the Pediatric Head and Brain

NASA Astrophysics Data System (ADS)

Margulies, Susan; Coats, Brittany

Traumatic brain injury (TBI) is a leading cause of death and disability among children and young adults in the United States and results in over 2,500 childhood deaths, 37,000 hospitalizations, and 435,000 emergency department visits each year (Langlois et al. 2004). Computational models of the head have proven to be powerful tools to help us understand mechanisms of adult TBI and to determine load thresholds for injuries specific to adult TBI. Similar models need to be developed for children and young adults to identify age-specific mechanisms and injury tolerances appropriate for children and young adults. The reliability of these tools, however, depends heavily on the availability of pediatric tissue material property data. To date the majority of material and structural properties used in pediatric computer models have been scaled from adult human data. Studies have shown significant age-related differences in brain and skull properties (Prange and Margulies 2002; Coats and Margulies 2006a, b), indicating that the pediatric head cannot be modeled as a miniature adult head, and pediatric computer models incorporating age-specific data are necessary to accurately mimic the pediatric head response to impact or rotation. This chapter details the developmental changes of the pediatric head and summarizes human pediatric properties currently available in the literature. Because there is a paucity of human pediatric data, material properties derived from animal tissue are also presented to demonstrate possible age-related differences in the heterogeneity and rate dependence of tissue properties. The chapter is divided into three main sections: (1) brain, meninges, and cerebral spinal fluid (CSF); (2) skull; and (3) scalp.

A Cochrane review of the evidence for non-surgical interventions for flexible pediatric flat feet.

Evans, A M; Rome, K

2011-03-01

The pediatric flat foot is a frequent presentation in clinical practice, a common concern to parents and continues to be debated within professional ranks. As an entity, it is confused by varied classifications, the notion of well-intended prevention and unsubstantiated, if common, treatment. The available prevalence estimates are all limited by variable sampling, assessment measures and age groups and hence result in disparate findings (0.6-77.9%). Consistently, flat foot has been found to normally reduce with age. The normal findings of flat foot versus children's age estimates that approximately 45% of preschool children, and 15% of older children (average age 10 years) have flat feet. Few flexible flat feet have been found to be symptomatic. Joint hypermobility and increased weight or obesity may increase flat foot prevalence, independently of age. Most attempts at classification of flat foot morphology include the arch, heel position and foot flexibility. Usual assessment methods are footprint measures, X-rays and visual (scaled) observations. There is no standardized framework from which to evaluate the pediatric flat foot. The pediatric flat foot is often unnecessarily treated, being ill-defined and of uncertain prognosis. Contemporary management of the pediatric flat foot is directed algorithmically within this review, according to pain, age, flexibility; considering gender, weight, and joint hypermobility. When foot orthoses are indicated, inexpensive generic appliances will usually suffice. Customised foot orthoses should be reserved for children with foot pain and arthritis, for unusual morphology, or unresponsive cases. Surgery is rarely indicated for pediatric flat foot (unless rigid) and only at the failure of thorough conservative management. The assessment of the pediatric flatfoot needs to be considered with reference to the epidemiological findings, where there is consensus that pediatric flexible flat foot reduces with age and that most children are asymptomatic. Globally, there is need for a standard by which the pediatric flat foot is assessed classified and managed. Until then, assessment should utilize the available evidence-based management model, the p-FFP Future research needs to evaluate the pediatric flat foot from representative samples, of healthy and known disease-group children prospectively, and using validated assessment instruments. The preliminary findings of the benefits of foot exercises, and discrete investigation into the effects of shoes and footwear use are also warranted.

The International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form is a patient-reported outcome with adult (1998) and pediatric (2011) versions validated at different ages. Prior longitudinal studies of patients aged 13 to 17 years who tore their anterior cruciate ligament (ACL) have used the only available adult IKDC, whereas currently the pediatric IKDC is the accepted form of choice. This study compared the adult and pediatric IKDC forms and tested whether the differences were clinically significant. The hypothesis was that the pediatric and adult IKDC questionnaires would show no clinically significant differences in score when completed by patients aged 13 to 17 years. Cohort study (diagnosis); Level of evidence, 2. A total of 100 participants aged 13 to 17 years with knee injuries were split into 2 groups by use of simple randomization. One group answered the adult IKDC form first and then the pediatric form. The second group answered the pediatric IKDC form first and then the adult form. A 10-minute break was given between form administrations to prevent rote repetition of answers. Study design was based on established methods to compare 2 forms of patient-reported outcomes. A 5-point threshold for clinical significance was set below previously published minimum clinically important differences for the adult IKDC. Paired t tests were used to test both differences and equivalence between scores. By ordinary least-squares models, scores were modeled to predict adult scores given certain pediatric scores and vice versa. Comparison between adult and pediatric IKDC scores showed a statistically significant difference of 1.5 points; however, the 95% CI (0.3-2.6) fell below the threshold of 5 points set for clinical significance. Further equivalence testing showed the 95% CI (0.5-2.4) between adult and pediatric scores being within the defined 5-point equivalence region. The scores were highly correlated, with a linear relationship (R(2) = 92%). There was no clinically significant difference between the pediatric and adult IKDC form scores in adolescents aged 13 to 17 years. This result allows use of whichever form is most practical for long-term tracking of patients. A simple linear equation can convert one form into the other. If the adult questionnaire is used at this age, it can be consistently used during follow-up. © 2015 The Author(s).

Invasive fungal infections are one of the major complications in pediatric patients during prolonged neutropenia after chemotherapy. Evaluation of the efficacy and safety of the triazole posaconazole in these patients is missing. This multicenter survey analyzed trough concentrations of 33 pediatric patients with a median age of 8 years during 108 neutropenic episodes who received prophylactic posaconazole oral suspension. A total of 172 posaconazole trough levels were determined to median 438 ng/ml (range 111-2011 ng/ml; mean 468 ± 244 ng/ml). Age and gender had no influence on posaconazole plasma levels. Posaconazole was not discontinued due to adverse events in any of the patients. Only hepatic parameters significantly increased beyond the upper normal limit to median values of ALT of 87 U/l (P < .0001), and AST of 67 U/l (P < .0001). One patient with a median posaconazole trough concentration of 306 ng/ml experienced an invasive fungal infection. In conclusion, posaconazole was effective, safe and feasible in 33 pediatric patients with neutropenia ≥5 days after chemotherapy. Median posaconazole plasma concentrations were approximately 1.6-fold lower than the recommended plasma level of 700 ng/ml. Larger patient cohorts are needed to evaluate these findings. © The Author 2016. Published by Oxford University Press on behalf of The International Society for Human and Animal Mycology.

The bleeding time may be longer in children than in adults.

PubMed

Sanders, J M; Holtkamp, C A; Buchanan, G R

1990-01-01

The bleeding time, the most frequently performed test reflecting in vivo platelet function, is the duration of blood flow from a standardized incision on the volar surface of the forearm. Normal values have been determined in adult subjects, but with the exception of neonates, data on the range of bleeding time values in pediatric patients are unavailable. Standard hematology textbooks imply that bleeding time values in children are similar to those of adults. We have reviewed our 9 years of experience with 137 children (mean age 6.5 years) who were referred for diagnostic evaluation of a bleeding disorder but whose history and physical examination were felt by us to be inconsistent with an abnormality of hemostasis. Bleeding time values in these individuals (mean 6.0 min, 95th percentile 9.0 min) were compared with those of 85 normal adult volunteers (mean 4.4 min, 95th percentile 6.5 min). The Simplate-I disposable device and vertical (perpendicular to elbow crease) incision direction were used in both groups. This difference between the pediatric and adult bleeding time values is statistically significant (p less than 0.0001). Neither age nor sex had a significant effect on the pediatric bleeding time measurements. We conclude that the bleeding time, when performed as described, is longer in children than in adults and that pediatric standards for bleeding time should be used in order to avoid a spurious diagnosis of a primary hemostatic disorder in some normal children.

To describe procedural characteristics of tracheal intubation (TI) during cardiopulmonary resuscitation (CPR) in a pediatric emergency department, and to characterize interruptions in CPR associated with TI performance. Retrospective single center case series. Resuscitations in a pediatric ED are videorecorded for quality improvement. Children who underwent TI while receiving chest compressions were eligible for inclusion. Intubations done by methods other than direct laryngoscopy were excluded. Background data included patient age and training background of intubator. Data on intubation attempts (success, laryngoscopy time) and chest compressions (interruptions, duration of pauses) were collected. Between December 2012 and February 2014, 32 patients had 59 TI attempts performed during CPR. Overall first attempt success at TI was 15/32 (47%); a median of 2 attempts were made per patient (range 1 to 4). Median laryngoscopy time was 47s (range 8-115s). 32/59 (54%) TI attempts had an associated interruption in CPR; the median interruption duration was 25s (range 3-64s). TI attempts without interruption in CPR were successful in 20/32 (63%) compared to 11/27 (41%) when CPR was paused (p=0.09). Laryngoscopy time was not significantly different between TI attempts with (47±21s) and without (47±26s; p=0.2) interruptions in compressions. 25/32 (78%) of pauses exceeded 10s in duration. TI during pediatric CPR results in significant interruptions in chest compressions. Procedural outcomes were not significantly different between attempts with and without compressions paused. In children receiving CPR, TI should be performed without pausing chest compressions. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

To study the efficacy of a new technique of single self-linking silicone stent exclusively in pediatric external dacryocystorhinostomy (DCR) and to report the new use and advantages of endoscopic guidance for the same. Prospective interventional case series, including 11 eyes of ten patients with nasolacrimal duct obstruction. Data collected included demographic data, clinical presentation, laterality, status of lids and puncta, syringing findings, probing interpretations, types and duration of intubation. Consecutive pediatric patients with post-saccal obstruction who underwent an external dacryocystorhinostomy were included. Exclusion criteria included patients who had undergone a DCR in the past by any route via external, endonasal or transcanalicular. Primary outcome measures were stent retention and ease of stent removal. Secondary outcome measures were anatomic patency of the passage and resolution of symptoms. There were three male and seven female patients. Mean age was 9.4 years (range 6-15). A total of 11 procedures were carried out. Following placement of self-linked stents, the removal was done at a mean duration of 13.2 weeks (range:12-16 weeks). None of the patients had a stent prolapse during this period. All stents were removed in the outpatient without the use of general anesthesia with minimal endoscopic guidance. A minimum follow-up of three months following removal was considered for final analysis. Follow-up ranged from three months to six months after tube removal. The anatomical and functional success rate was 91%. There was one anatomical failure three months following tube removal and the remaining patients were free of symptoms at the last follow-up. Self-linking stents are a useful modality in pediatric patients not only to prevent stent prolapse but also to allow easy removal with minimum discomfort. Endoscopic guidance is a useful addition to this technique.

How young can children reliably and validly self-report their health-related quality of life?: an analysis of 8,591 children across age subgroups with the PedsQL 4.0 Generic Core Scales.

The last decade has evidenced a dramatic increase in the development and utilization of pediatric health-related quality of life (HRQOL) measures in an effort to improve pediatric patient health and well-being and determine the value of healthcare services. The emerging paradigm shift toward patient-reported outcomes (PROs) in clinical trials has provided the opportunity to further emphasize the value and essential need for pediatric patient self-reported outcomes measurement. Data from the PedsQL DatabaseSM were utilized to test the hypothesis that children as young as 5 years of age can reliably and validly report their HRQOL. The sample analyzed represented child self-report age data on 8,591 children ages 5 to 16 years from the PedsQL 4.0 Generic Core Scales DatabaseSM. Participants were recruited from general pediatric clinics, subspecialty clinics, and hospitals in which children were being seen for well-child checks, mild acute illness, or chronic illness care (n = 2,603, 30.3%), and from a State Children's Health Insurance Program (SCHIP) in California (n = 5,988, 69.7%). Items on the PedsQL 4.0 Generic Core Scales had minimal missing responses for children as young as 5 years old, supporting feasibility. The majority of the child self-report scales across the age subgroups, including for children as young as 5 years, exceeded the minimum internal consistency reliability standard of 0.70 required for group comparisons, while the Total Scale Scores across the age subgroups approached or exceeded the reliability criterion of 0.90 recommended for analyzing individual patient scale scores. Construct validity was demonstrated utilizing the known groups approach. For each PedsQL scale and summary score, across age subgroups, including children as young as 5 years, healthy children demonstrated a statistically significant difference in HRQOL (better HRQOL) than children with a known chronic health condition, with most effect sizes in the medium to large effect size range. The results demonstrate that children as young as the 5 year old age subgroup can reliably and validly self-report their HRQOL when given the opportunity to do so with an age-appropriate instrument. These analyses are consistent with recent FDA guidelines which require instrument development and validation testing for children and adolescents within fairly narrow age groupings and which determine the lower age limit at which children can provide reliable and valid responses across age categories.

To review the clinical manifestations and operative management of a large contemporary pediatric cohort of patients with prune-belly syndrome (PBS). PBS patients aged <21 years followed up in our pediatric urology clinic were identified by the International Classification of Diseases, Ninth Revision code (756.71). Demographics, concomitant diagnoses, surgical history, imaging studies, and renal or bladder function were evaluated. Data were available for 46 pediatric patients (44 boys and 2 girls). Mean age was 7.6 ± 4.7 years (range, 0.9-20 years). Average length of clinical follow-up was 6.8 ± 5 years. Forty-five children (97.8%) had hydroureteronephrosis, and 36 of them (78.3%) had vesicoureteral reflux. Five patients (10.9%) had significant pulmonary insufficiency, and 2 patients (4.3%) were oxygen dependent. Eighteen children (39.1%) had other congenital malformations, including cardiac in 4 patients (8.7%) and musculoskeletal anomalies in 10 patients (21.7%). Orchidopexy was the most common surgery, with all boys aged ≥3 years having undergone the procedure. Twenty-two patients (47.8%) had a history of ureteral surgery, 22 (47.8%) had bladder surgery, 11 (23.9%) had renal surgery, and 6 (13%) had urethral procedures. Nineteen patients (41.3%) underwent abdominoplasty. Eighteen children (39.1%) had documented chronic kidney disease, and 8 children (17.4%) underwent renal transplantation. Average age at transplantation was 5.1 ± 2.9 years. The mean nadir creatinine level for patients with end-stage renal disease was 1.4 mg/dL compared with 0.4 mg/dL for those not requiring transplantation (P <.001). Children with PBS have significant comorbidities and require frequent operative intervention, with disease heterogeneity necessitating an individualized management approach. Early end-stage renal disease is prevalent, with approximately 15% of children requiring kidney transplantation. Copyright © 2015 Elsevier Inc. All rights reserved.

Multicenter study of crystalloid boluses and transfusion in pediatric trauma-When to go to blood?

The 9th edition of Advanced Trauma Life Support recommends up to three crystalloid boluses in pediatric trauma patients with consideration of transfusion after the second bolus; however, this approach is debated. We aimed to determine if requirement of more than one fluid bolus predicts the need for transfusion. The 2010 to 2016 highest tier activation patients younger than 15 years from two ACS Level I pediatric trauma centers were identified from prospectively maintained trauma databases. Those with a shock index (heart rate/systolic blood pressure) greater than 0.9 were included. Crystalloid boluses (20 ± 10 mL/kg) and transfusions administered prehospital and within 12 hours of hospital arrival were determined. Univariate and multivariable analyses were conducted to determine association between crystalloid volume and transfusion. Among 208 patients, the mean age was 5 ± 4 years (60% male), 91% sustained blunt injuries, and median (interquartile range) Injury Severity Score was 11 (6,25). Twenty-nine percent received one bolus, 17% received two, and 10% received at least three. Transfusion of any blood product occurred in 50 (24%) patients; mean (range) red blood cells was 23 (0-89) mL/kg, plasma 8 (0-69), and platelets 1 (0-18). The likelihood of transfusion increased logarithmically from 11% to 43% for those requiring 2 or more boluses (Fig. 1). This relationship persisted on multivariable analysis that adjusted for institution, age, and shock index with good discrimination (Area under the Receiver Operating Characteristic, 0.84). Shock index was also strongly associated with transfusion. Almost half of pediatric trauma patients with elevated shock index require transfusion following two crystalloid boluses and the odds of requiring a transfusion plateau at this point in resuscitation. This supports consideration of blood with the second bolus in conjunction with shock index though prospective studies are needed to confirm this and its impact on outcomes. Therapeutic study, level IV.

There are no studies evaluating the pharmacokinetics of enoxaparin in the hospitalized pediatric patient population. To characterize the pharmacokinetics of enoxaparin in pediatric patients. A retrospective review of inpatients 1 to 18 years of age admitted to our institution who received enoxaparin with anti-factor Xa activity level monitoring was performed. Demographic variables, enoxaparin dosing, and anti-factor Xa activity levels were collected. Population pharmacokinetic analysis was performed with bootstrap analysis. Simulation (n = 10 000) was performed to determine the percentage who achieved targeted anti-Xa levels at various doses. A total of 853 patients (male 52.1%, median age = 12.2 years; interquartile range [IQR] = 4.6-15.8 years) received a mean enoxaparin dose of 0.86 ± 0.31 mg/kg/dose. A median of 3 (IQR = 1-5) anti-factor Xa levels were sampled at 4.4 ± 1.3 hours after a dose, with a mean anti-factor Xa level of 0.52 ± 0.23 U/mL. A 1-compartment model best fit the data, and significant covariates included allometrically scaled weight, serum creatinine, and hematocrit on clearance, and platelets on volume of distribution. Simulations were run for patients both without and with reduced kidney function (creatinine clearance of ≤30 mL/min/1.73 m 2 ). A dose of 1 mg/kg/dose every 12 hours had the highest probability (72.3%) of achieving an anti-Xa level within the target range (0.5-1 U/mL), whereas a dose reduction of ~30% achieved the same result in patients with reduced kidney function. Pediatric patients should initially be dosed at 1-mg/kg/dose subcutaneously every 12 hours for treatment of thromboembolism followed by anti-Xa activity monitoring. Dose reductions of ~30% for creatinine clearance ≤30 mL/min/1.73 m 2 are required.

Non-Hodgkin lymphoma (NHL) accounts for 8–10% of all childhood cancers. NHL collectively represents various lymphoid malignancies with diverse clinicopathological and biological characteristics. In this study, we aimed to describe the epidemiological and clinicopathological characteristics and treatment outcomes of pediatric NHL patients treated at the Pediatric Oncology Unit of Zagazig University Hospital and the Benha Specialized Pediatric Hospital. We conducted a cross-sectional retrospective study by reviewing the medical records of 142 patients admitted with a diagnosis of NHL over a period of 8 years (February, 2004 to February, 2012) in these two Oncology Units. The age at presentation ranged between 2 and 15 years, with a mean ± standard deviation (SD) of 6.1±2.8 years and a male:female ratio of 1.7:1. Abdominal involvement was the most common presentation (73.2%). Burkitt's lymphoma (BL) was the most common NHL subtype (69%), followed by lymphoblastic lymphoma, diffuse large B-cell lymphoma and anaplastic large-cell lymphoma, accounting for 18.3, 10.6 and 2.1% of the cases, respectively. The majority of the patients (88.7%) had been diagnosed with advanced disease (Murphy stage III/IV). Complete remission was achieved in 120 cases (84.5%). A total of 16 patients (11.3%) succumbed to the disease during the first few months and 6 patients (4.2%) remained alive following relapse. The mean follow-up duration ± SD was 34.6±25.1 months (range, 3–84 months). The 5-year overall survival (OS) and event-free survival (EFS) rates were 88.7 and 85.1%, respectively. None of the clinical, epidemiological or pathological variables exhibited a statistically significant association with the OS or EFS. In conclusion, NHL occurs at a younger age, with a higher incidence of BL and advanced-stage disease. The outcome of NHL in our two centers was satisfactory, approaching the international rates.

Objective To describe pediatric patients with convulsive refractory status epilepticus (RSE) in whom there is intention-to-use an intravenous anesthetic for seizure control. Design Two-year prospective observational study evaluating patients (age range one month to 21 years) with RSE not responding to two antiepileptic drug classes and treated with continuous infusion of anesthetic agent. Setting Nine pediatric hospitals in the United States. Patients In a cohort of 111 patients with RSE (median age 3.7 years, 50% male), 54 (49%) underwent continuous infusion of anesthetic treatment. Main Results The median (interquartile range, IQR) intensive care unit length-of-stay was 10 (3–20) days. Up to four ‘cycles’ of serial anesthetic therapy were used and seizure termination was achieved in 94% by the second cycle. Seizure duration in controlled patients was 5.9 (1.9–34) hours for the first cycle, and longer when a second cycle was required (30 [4,−120] hours, p=0.048). Midazolam was the most frequent first-line anesthetic agent (78%); pentobarbital was the most frequently used second-line agent after midazolam failure (82%). An electroencephalographic endpoint was used in over half of the patients; higher midazolam dosing was used with a burst suppression endpoint. In midazolam non-responders, transition to a second agent occurred after a median of one day. Most patients (94%) experienced seizure termination with these two therapies. Conclusions Midazolam and pentobarbital remains the mainstay of continuous infusion therapy for RSE in the pediatric patient. The majority of patients experience seizure termination within a median of 30 hours. These data have implications for the design and feasibility of future intervention trials. That is, testing a new anesthetic anticonvulsant after failure of both midazolam and pentobarbital is unlikely to be feasible in a pediatric study, whereas a decision to test an alternative to pentobarbital, after midazolam failure, may be possible in a multicenter multinational study.

Skull base chordomas in children are extremely rare. Their course, management, and outcome have not been defined. To describe the preeminent clinical and radiological features in a series of pediatric patients with skull base chordomas and analyze the outcome of a cohort who underwent uniform treatment. We emphasize predictors of overall survival and progression-free survival, which aligns with Collins' law for embryonal tumors. Thirty-one patients with a mean age of 10.7 yr (range 0.8-22) harboring skull base chordomas were evaluated. We retrospectively analyzed the outcomes and prognostic factors for 18 patients treated by the senior author, with uniform management of surgery with the aim of gross total resection and adjuvant proton-beam radiotherapy. Mean follow-up was 119.2 mo (range 8-263). Abducens nerve palsy was the most common presenting symptom. Imaging disclosed large tumors that often involve multiple anatomical compartments. Patients undergoing gross total resection had significantly increased progression-free survival (P = .02) and overall survival (P = .05) compared with those having subtotal resection. Those who lived through the period of risk for recurrence without disease progression had a higher probability of living entirely free of progression (P = .03; odds ratio = 16.0). Age, sex, and histopathological variant did not yield statistical significance in survival. Long-term overall and progression-free survival in children harboring skull base chordomas can be achieved with gross surgical resection and proton-beam radiotherapy, despite an advanced stage at presentation. Collins' law does apply to pediatric skull base chordomas, and children with this disease have a high hope for cure.

The psychological well-being of siblings of children with life threatening illness remains largely uncharted. Pediatric cancer research suggests that a supportive family environment may protect the psychological well-being of siblings. We hypothesized that (1) siblings of pediatric palliative care patients would show clinical/behavioral scores that were elevated but that rates of serious psychopathology would be comparable to the general population of children their age; and (2) higher family functioning scores would be associated with lower clinical scores and higher adaptive scores for these siblings. We conducted an observational study with families in which a patient receiving palliative care had one or more siblings between the ages of 6 and 11. Parents completed the Behavioral Assessment System for Children, Second Edition (BASC-2) to assess the siblings' psychological well-being and the Family Assessment Device (FAD) to assess the family environment. Twenty-four parents reported data for 30 siblings. Only three siblings scored in the clinical range on a BASC-2 composite clinical scale, and 11 siblings scored in the at-risk range on one or more composite scales. Higher FAD scores predicted significantly higher externalization composite clinical scores (7.54, 95% CI: 1.12, 13.97, p < 0.05) and significantly higher behavioral composite scores (7.88, 95% CI: 1.55, 14.21, p < 0.05). Siblings of pediatric palliative care patients are not experiencing lower psychological well-being than the general population. The prediction that a positive family environment would be associated with higher levels of psychological health was supported.

We evaluated the long-term results of visual internal urethrotomy for pediatric urethral strictures to evaluate the efficacy and final outcome of this procedure in children and to evaluate the risk factors for stricture recurrence. The computerized surgical records of our hospital were reviewed to identify children who underwent visual internal urethrotomy between 1980 and 2001. Hospital and followup clinical charts were then reviewed. Many variables were analyzed, including age, etiology, length and site of the strictures, and catheter duration. Only patients with a minimum followup of 2 years were included. Regular self-catheterization was not used by any child. A total of 31 patients (mean age 11.2 years, range 2 to 18) were identified. Followup ranged from 2 to 20 years, with a mean of 6.6 years. The most common etiology for stricture formation was failed previous urethroplasty and post instrumentation (35.5% and 32.3%, respectively). The success rate after initial urethrotomy was 35.5% (11 of 31 patients). Mean interval to first recurrence was 26 months. A second urethrotomy improved the success rate of 58.1%. Eight patients required 2 or more urethrotomies, of whom half required open urethroplasty. Among the evaluated variables only stricture length shorter than 1 cm was associated with good results. Visual internal urethrotomy provides a safe first line therapeutic option for pediatric urethral strictures shorter than 1 cm, independent of etiology and location. For patients with more than 1 recurrence or with strictures longer than 1 cm, who are at high risk for recurrence after internal urethrotomy, open urethroplasty remains the treatment of choice.

Purpose: Survivors of pediatric and young adult cancer are at increased risk for treatment-related problems. Yet, few survivors receive risk-based care. The treatment summary and care plan are recommended to improve understanding of cancer treatment, potential late effects, and recommended screening. It is unknown whether survivors retain, understand, value, and disseminate the document, and whether it causes worry. Methods: We surveyed 111 adult survivors of pediatric and young adult cancer 1 to 6 weeks after receipt of a one-page treatment summary and care plan (response rate, 96%). Participants answered questions regarding retention, understanding, value, dissemination, concern, and preferences. Results: Participants were majority female (58%), college-educated (60%), diagnosed with cancer before age 21 (76%), on average 18 years from diagnosis (range, 2 to 50 years), and treated with radiation and chemotherapy (61%). Median age was 30 years (range, 18 to 65 years). A majority of participants stated that they understood the treatment summary (95%), retained the document (95%), and valued it (92%). A minority reported that the document caused concern (14%) or wanted more information than the form provided (20%). Although the time between receipt of the document and survey was brief, many described dissemination of the document to their personal circle (44%) or an outside provider (10 [33%] of 30 who saw an outside doctor). Conclusion: A one-page treatment summary and care plan was well-received and did not cause report of undue concern. Additional health-related information was requested by some, and dissemination to outside providers could be improved. PMID:22942816

Background Consistent localization of cerebellar cortex in a standard coordinate system is important for functional studies and detection of anatomical alterations in studies of morphometry. To date, no pediatric cerebellar atlas is available. New method The probabilistic Cape Town Pediatric Cerebellar Atlas (CAPCA18) was constructed in the age-appropriate National Institute of Health Pediatric Database asymmetric template space using manual tracings of 16 cerebellar compartments in 18 healthy children (9–13 years) from Cape Town, South Africa. The individual atlases of the training subjects were also used to implement multi atlas label fusion using multi atlas majority voting (MAMV) and multi atlas generative model (MAGM) approaches. Segmentation accuracy in 14 test subjects was compared for each method to ‘gold standard’ manual tracings. Results Spatial overlap between manual tracings and CAPCA18 automated segmentation was 73% or higher for all lobules in both hemispheres, except VIIb and X. Automated segmentation using MAGM yielded the best segmentation accuracy over all lobules (mean Dice Similarity Coefficient 0.76; range 0.55–0.91). Comparison with existing methods In all lobules, spatial overlap of CAPCA18 segmentations with manual tracings was similar or higher than those obtained with SUIT (spatially unbiased infra-tentorial template), providing additional evidence of the benefits of an age appropriate atlas. MAGM segmentation accuracy was comparable to values reported recently by Park et al. (2014) in adults (across all lobules mean DSC = 0.73, range 0.40–0.89). Conclusions CAPCA18 and the associated multi atlases of the training subjects yield improved segmentation of cerebellar structures in children. PMID:26743973

Leukocoria is the most common presenting sign for pediatric eye disease including retinoblastoma and cataract, with worse outcomes if diagnosis is delayed. We investigated whether individuals could identify leukocoria in photographs (photoleukocoria) and examined their subsequent Internet search behavior. Using a web-based questionnaire, in this cross-sectional study we invited adults aged over 18 years to view two photographs of a child with photoleukocoria, and then search the Internet to determine a possible diagnosis and action plan. The most commonly used search terms and websites accessed were recorded. The questionnaire was completed by 1639 individuals. Facebook advertisement was the most effective recruitment strategy. The mean age of all respondents was 38.95 ± 14.59 years (range, 18-83), 94% were female, and 59.3% had children. An abnormality in the images presented was identified by 1613 (98.4%) participants. The most commonly used search terms were: "white," "pupil," "photo," and "eye" reaching a variety of appropriate websites or links to print or social media articles. Different words or phrases were used to describe the same observation of photoleukocoria leading to a range of websites. Variations in the description of observed signs and search words influenced the sites reached, information obtained, and subsequent help-seeking intentions. Identifying the most commonly used search terms for photoleukocoria is an important step for search engine optimization. Being directed to the most appropriate websites informing of the significance of photoleukocoria and the appropriate actions to take could improve delays in diagnosis of important pediatric eye disease such as retinoblastoma or cataract.

The purpose of this study was to measure the scattered dose to out-of-field organs from head and neck radiotherapy in pediatric patients and to estimate the risk for second cancer induction to individual organs. Radiotherapy for thalamic tumor, brain tumor, acute leukemia and Hodgkin's disease in the neck region was simulated on 5 and 10-year-old pediatric phantoms with a 6 MV photon beam. The radiation dose to thyroid, breast, lung, stomach, ovaries, bladder, liver, uterus, prostate and colon was measured using thermoluminescent dosimeters. The methodology, provided by the BEIR VII report was used for the second cancer risk estimations. Peripheral dose range for a simulated 5-year-old patient was 0.019%-1.572% of the given tumor dose. The corresponding range at the advanced patient age was reduced to 0.018%-1.468%. The second cancer risk per fraction for male patients varied from 3 to 215 per 1,000,000 patients depending upon the age at the time of exposure, primary cancer site and organ scattered dose. The corresponding risk for females was 1-1186 per 1,000,000 patients. The higher risk values were found for breast, thyroid and lung cancer development. The current data concerning the risk magnitude for developing subsequent neoplasms to various out-of-field organs may be of value for health care professionals in the follow-up studies of childhood cancer survivors.

To assess and relate the nutritional status by type of abuse in a pediatric population diagnosed with physical abuse (PA) and sexual abuse (SA). It's a retrospective, cross-sectional, descriptive study of 178 clinical records of children aged less than 12 years, attended at the Clinic for the Integral Care of the Abused Child of the Instituto Nacional de Pediatría and the Universidad Nacional Autónoma de México (CAINM-INP-UNAM), during the period 1994 to 2005. The relationship of nutritional status with the type of abuse was analyzed in two age ranges (3 months to less than five years, and five to 11 years) and gender with Student t and chi-square tests. We identified that, in girls PA was associated with stunting (PA: 48% vs. SA: 12%, p < 0.005 and PA: 21% vs. SA: 0%, p < 0.002) and wasting (PA: 21% vs. SA: 0%, p < 0.01 and PA: 21% vs. SA: 0%, p < 0.002). Whereas in girls SA was associated with overweight and obesity in age range five to 11 years (PA: 0% vs. SA: 31%; p < 0.01). This study identified acute and chronic under nutrition in girls with PA, and overweight and obesity in girls with SA. These findings enrich the knowledge for the suspicion of maltreatment child syndrome during the search of the aetiology of the clinical expression studied.

The efficacy of nonsurgical interventions for pediatric flexible flat foot: a critical review.

The pediatric flat foot frequently presents as a common parental concern in the health care setting. Foot orthoses are often used, yet benefits are uncertain and disputed, having been variably investigated. A recent Cochrane review cites limited evidence for nonsurgical interventions. This critical and structured review evaluates the effect of pediatric foot orthoses from assessment of the current literature. A systematic search of the following electronic databases: Medline, CINAHL, AMED, and SPORTDiscus, using an array of search terms. A further search was also performed on relevant reference listings. Inclusion criteria were peer-reviewed journal articles, publication date from 1970 onwards, in the English language. Exclusion criteria were surgery interventions, adult subjects, rigid flat foot, articles based on opinion. A structured Quality Index was used to evaluate the research quality of articles. Three reviewers independently assessed the studies with disputes resolved by majority consensus. Studies were then grouped according to the outcome measures used. Thirteen articles, from an initial 429, met the criteria for quality evaluation. The mean Quality Index score was 35% (range: 13% to 81%), indicative of generally poor and varying methodological quality. The low quality of the studies negates definitive conclusions. Only 3/13 quality evaluations scored > 50%; hence, evidence for efficacy of nonsurgical interventions for flexible pediatric flat feet is very limited. Future research needs validated foot type assessment, applicable outcome measures for the intervention, the use of control groups, allowance for independent effects of footwear, age range comparisons, larger samples, and prospective, longer follow-up. There is very limited evidence for the efficacy of nonsurgical interventions for children with flexible flat feet. Clinicians need to consider the lack of good-quality evidence in their decision-making for the management of pediatric flat foot.

An external evaluation of phenobarbital population pharmacokinetic model described by Marsot et al. was performed in pediatric intensive care unit. Model evaluation is an important issue for dose adjustment. This external evaluation should allow confirming the proposed dosage adaptation and extending these recommendations to the entire intensive care pediatric population. External evaluation of phenobarbital published population pharmacokinetic model of Marsot et al. was realized in a new retrospective dataset of 35 patients hospitalized in a pediatric intensive care unit. The published population pharmacokinetic model was implemented in nonmem 7.3. Predictive performance was assessed by quantifying bias and inaccuracy of model prediction. Normalized prediction distribution errors (NPDE) and visual predictive check (VPC) were also evaluated. A total of 35 infants were studied with a mean age of 33.5 weeks (range: 12 days-16 years) and a mean weight of 12.6 kg (range: 2.7-70.0 kg). The model predicted the observed phenobarbital concentrations with a reasonable bias and inaccuracy. The median prediction error was 3.03% (95% CI: -8.52 to 58.12%), and the median absolute prediction error was 26.20% (95% CI: 13.07-75.59%). No trends in NPDE and VPC were observed. The model previously proposed by Marsot et al. in neonates hospitalized in intensive care unit was externally validated for IV infusion administration. The model-based dosing regimen was extended in all pediatric intensive care unit to optimize treatment. Due to inter- and intravariability in pharmacokinetic model, this dosing regimen should be combined with therapeutic drug monitoring. © 2017 Société Française de Pharmacologie et de Thérapeutique.

Negative-Pressure Ventilation in Pediatric Acute Respiratory Failure.

2017-12-01

The objective of this work was to describe the use of negative-pressure ventilation (NPV) in a heterogeneous critically ill, pediatric population. A retrospective chart review was conducted of all patients admitted to a pediatric ICU with acute respiratory failure supported with NPV from January 1, 2012 to May 15, 2015. Two hundred thirty-three subjects at a median age of 15.5 months were supported with NPV for various etiologies, most commonly bronchiolitis (70%). Median (interquartile range) duration of support was 18.7 (8.7-34.3) h. The majority were NPV responders (70%), defined as not needing escalation to any form of positive-pressure ventilation. In non-responders, escalation occurred at a median (interquartile range) of 6.9 (3.3-16.6) h. More NPV non-responders had upper-airway obstruction ( P = .02), and fewer had bronchiolitis ( P = .008) compared with responders. A bedside scoring system developed on these data was 98% specific in predicting NPV failure by 4 h after NPV start (area under the curve 0.759, 95% CI 0.675-0.843, P < .001). Complications from NPV were rare (3%); however, delayed enteral nutrition (33%) and continuous intravenous sedation use (51%) in children while receiving NPV were more frequent. The annual percentage of pediatric ICU admissions requiring intubation declined by 28% in the 3 y after NPV introduction, compared with the 3 y prior. NPV is a noninvasive respiratory support for pediatric acute respiratory failure from all causes with few complications and a 70% response rate. Children receiving NPV often required intravenous sedation for comfort, and one third received delayed enteral nutrition. Those who required escalation from NPV worsened within 6 h; this may be predictable with a bedside scoring system. Copyright © 2017 by Daedalus Enterprises.

Darbepoetin alfa is a commonly prescribed erythropoiesis-stimulating agent (ESA) for correcting anemia in pediatric chronic kidney disease (CKD) patients. However, little information exists on its use in ESA-naïve patients. This study evaluated the efficacy and safety of darbepoetin alfa in pediatric patients initiating ESA therapy. One-hundred sixteen pediatric ESA-naïve subjects (aged 1-18 years) with CKD stages 3-5D and hemoglobin (Hb) <10 g/dl from 43 centers in the US, Europe, and Mexico were randomized by age (three groups) and dialysis status (yes vs. no) to receive darbepoetin alfa once weekly (QW) or every 2 weeks (Q2W) subcutaneously (not on dialysis and peritoneal dialysis subjects) and intravenously (hemodialysis subjects). The drug was titrated to achieve Hb levels of 10.0-12.0 g/dl over 25 weeks. Patient- and parent-reported health-related outcomes were measured by the Pediatric Quality of Life Inventory (PedsQL™) in children ≥2 years. In both groups, mean Hb concentrations increased to ≥11.0 g/dl over the first 3 months of treatment and remained stable within the 10.0-12.0 g/dl target range. The median time to achieve hemoglobin ≥10 g/dl was slightly longer for subjects <12 years (QW and Q2W, both 28 days) vs. those ≥12 years (23 and 22 days, respectively). Adverse event profiles were similar between groups, with QW, four (7%) and Q2W, five (9%). PedsQL™ scores showed modest increases. Darbepoetin alfa can be safely administered either QW or Q2W to ESA-naïve pediatric patients with CKD-related anemia to achieve Hb targets of 10.0-12.0 g/dl.

Ankle sprain is one of the most common musculoskeletal injuries among young athletes, and there remains a gap in the literature regarding susceptibility to such injuries among physically active youth. The primary purpose of this study was to determine the associations between sex, a history of ankle sprain, and ankle range of motion (ROM) in pediatric and adolescent athletes. Athletes under the age of 18 years old who presented to a sports injury prevention center underwent ankle ROM measurements including plantarflexion (PF), inversion (IV), and eversion (EV). A two-way analysis of covariance (ANCOVA) was performed to examine effect of sex and a history of ankle sprain on ROMs. Also, a binary logistic regression was performed to investigate variables that are associated with a history of ankle injury. Among 452 pediatric and adolescent athletes [268 females (13.6 ± 2.3 years old) and 184 males (13.3 ± 2.5 years old)], 128 reported a history of previous ankle sprain. Females demonstrated significantly increased ROMs (PF and IV bilaterally, and right EV) compared to males while there was no effect of a history of ankle sprain on ROMs. Female sex was independently associated with a history of ankle sprain. There was a strong effect of female sex on ROMs rather than a history of ankle injury history. Additionally, pediatric and adolescent females have greater odds of a history of ankle sprain when compared to their male counterparts.

Occult injuries are those likely to be missed on initial assessment by first responders and, though initially asymptomatic, they may present suddenly and lead to rapid patient decompensation. No scoring systems to quantify the occultness of pediatric injuries have been established. Such a scoring system will be useful in the creation of an Advanced Automotive Crash Notification (AACN) system that assists first responders in making triage decisions following a motor vehicle crash (MVC). The most frequent MVC injuries were determined for 0-4, 5-9, 10-14 and 15-18 year olds. For each age-specific injury, experts with pediatric trauma expertise were asked to rate the likelihood that the injury may be missed by first responders. An occult score (ranging from 0-1) was calculated by averaging and normalizing the responses of the experts polled. Evaluation of all injuries across all age groups demonstrated greater occult scores for the younger age groups compared to older age groups (mean occult score 0-4yo: 0.61 ± 0.23, 5-9yo: 0.53 ± 0.25, 10-14yo: 0.48 ± 0.23, and 15-18yo: 0.42 ± 0.22, p < 0.01). Body-region specific occult scores revealed that experts judged abdominal, spine and thoracic injuries to be more occult than injuries to other body regions. The occult scores suggested that injuries are more difficult to detect in younger age groups, likely given their inability to express symptoms. An AACN algorithm that can predict the presence of clinically undetectable injuries at the scene can improve triage of children with these injuries to higher levels of care.

The fractures of facial structures lead to great morbidity. Cross-sectional studies are needed to evaluate the current state of maxillofacial traumas. Thus, this study aims to evaluate these experiences and to compare these results with the current literature. The medical records of the maxillofacial fracture cases hospitalized between January 2004 and November 2011 were examined. The age, sex, etiology, fracture localization and treatment method for each case were documented. The affected facial bones were grouped as mandible, maxilla, zygoma, naso-orbitoethmoid complex (NOEC) and blow-out. Nasal fractures were excluded. The cases were assigned to 3 groups with respect to age (below 16, above 65 and between 17 and 64). The chi Square test was used to assess the significance of the difference in mandibular fracture rates in the pediatric population compared to others. The total number of cases was 152. The total number of fractures was 185. Of the 152 cases, 117 were male and 35 were female. The average age was 31.4 (±18.3), ranging between 2 and 81. Thirty-one cases were 16 years old or less. Nine cases were 65 years old or more. Mandibular and zygomatic fractures were the most prevalent fractures in the adult group. Mandibular fractures were significantly more common in the pediatric age group compared to rest of the population (X(2), p<0.05). Traffic accidents were the most common etiological factor, with a 55.3% ratio. Open reduction and internal fixation was the most frequently conducted treatment modality in all age groups. Retrospective studies are important for the projection of future prospects. In summary, our results indicate that pediatric fractures are mostly in the lower face and usually affect the condylar region, which is consistent with the literature.

Purpose: To report, from a longitudinal study, cognitive outcome in pediatric patients treated with proton radiation therapy (PRT) for central nervous system (CNS) tumors. Methods and Materials: Sixty patients receiving PRT for medulloblastoma (38.3%), gliomas (18.3%), craniopharyngioma (15.0%), ependymoma (11.7%), and other CNS tumors (16.7%) were administered age-appropriate measures of cognitive abilities at or near PRT initiation (baseline) and afterward (follow-up). Patients were aged ≥6 years at baseline to ensure consistency in neurocognitive measures. Results: Mean age was 12.3 years at baseline; mean follow-up interval was 2.5 years. Treatment included prior surgical resection (76.7%) and chemotherapy (61.7%). Proton radiation therapy included craniospinal irradiationmore » (46.7%) and partial brain radiation (53.3%). At baseline, mean Wechsler Full Scale IQ was 104.6; means of all 4 Index scores were also in the average range. At follow-up, no significant change was observed in mean Wechsler Full Scale IQ, Verbal Comprehension, Perceptual Reasoning/Organization, or Working Memory. However, Processing Speed scores declined significantly (mean 5.2 points), with a significantly greater decline for subjects aged <12 years at baseline and those with the highest baseline scores. Cognitive outcome was not significantly related to gender, extent of radiation, radiation dose, tumor location, histology, socioeconomic status, chemotherapy, or history of surgical resection. Conclusions: Early cognitive outcomes after PRT for pediatric CNS tumors are encouraging, compared with published outcomes from photon radiation therapy.« less

We investigated the clinical value of treating pediatric multiple kidney stones with extensive distribution using flexible ureteroscopic lithotripsy (FUL) combined with micro-percutaneous nephrolithotomy (micro-PNL). In total, 21 pediatric patients with multiple renal calculi between May 2016 and June 2017 received FUL combined with micro-PNL. The group included 13 boys and eight girls; the patients' mean age was 3.8 years (range 1-8 years). The maximum stone diameter ranged from 1.0 to 1.5 cm. FUL was first performed in the lithotomy position to fragment stones that were located in the renal pelvis, and upper and mid-renal calyx. Patients were then moved to a prone position, and micro-PNL was performed to treat lower pole stones that could not be reached by the flexible ureteroscope during FUL. Percutaneous renal access to the lower calyx was achieved using a 4.8F "all-seeing needle" with ultrasound guidance, and stone fragmentation was performed with a 200-μm holmium laser at different settings to disintegrate 1- to 2-mm fragments. All 21 pediatric patients with multiple kidney stones underwent combined FUL and micro-PNL. The stone free rate (SFR) was 85.7% (18/21). The mean surgical time was 45 min (range 30-70 min). The mean volume of irrigation fluid used was 480 mL (range 300-1200 mL). The mean surgical time for FUL and micro-PNL was 31 min and 14 min, respectively, and the mean volume of fluid used for FUL and micro-PNL was 360 mL and 120 mL, respectively. According to the modified Clavien classification, grade 1 and 2 postoperative complications occurred in five and one patients, respectively. The mean decrease in the level of hemoglobin was 0.4 g/dL (0-0.7 g/dL), and no patients required a transfusion. The average hospital stay was 3 days (range 2-5 days). Combined FUL and micro-PNL is a safe, effective, and minimally invasive operation to remove multiple renal calculi with extensive distribution in children in selected cases.

Living donor liver transplantation has become a cornerstone for the treatment of children with end-stage hepatic dysfunction, especially within populations or countries with low rates of organ utilization from deceased donors. The objective is to report our experience with 185 living donors operated on by a team pediatric surgeons in a tertiary center for pediatric liver transplantation. Retrospective analysis of medical records of donors of hepatic grafts for transplant undergoing surgery between June 1998 and March 2013. Over the last 14 years, 185 liver transplants were performed in pediatric recipients of grafts from living donors. Among the donors, 166 left lateral segments (89.7%), 18 left lobes without the caudate lobe (9.7%) and 1 right lobe (0.5%) were harvested. The donor age ranged from 16 to 53 years, and the weight ranged from 47 to 106 kg. In 10 donors, an additional graft of the donor inferior mesenteric vein was harvested to substitute for a hypoplastic recipient portal vein. The transfusion of blood products was required in 15 donors (8.1%). The mean hospital stay was 5 days. No deaths occurred, but complications were identified in 23 patients (12.4%): 9 patients experienced abdominal pain and severe gastrointestinal symptoms and 3 patients required reoperations. Eight donors presented with minor bile leaks that were treated conservatively, and 3 patients developed extra-peritoneal infections (1 wound collection, 1 phlebitis and 1 pneumonia). Eight grafts (4.3%) showed primary dysfunction resulting in recipient death (3 cases of fulminant hepatitis, 1 patient with metabolic disease, 1 patient with Alagille syndrome and 3 cases of biliary atresia in infants under 1 year old). There was no relation between donor complications and primary graft dysfunction (P=0.6). Living donor transplantation is safe for the donor and presents a low morbidity. The donor surgery may be performed by a team of trained pediatric surgeons. © 2014.

The optimal therapeutic regimen for managing childhood idiopathic nephrotic syndrome (INS) is still under debate. We have evaluated the choice of steroid regimen and of symptomatic treatment adopted by pediatricians and pediatric nephrologists in a large number of centers as the first step towards establishing a shared protocol This was a multicenter, retrospective study. A total of 231 children (132 admitted to pediatric units) aged 6 months to <15 years who presented with onset of nephrotic syndrome to 54 pediatric units and six pediatric nephrology units in Italy between 2007 and 2009 were eligible for entry into the study. Median steroid dosing was 55 (range 27-75) mg/m(2)/day. The overall median cumulative dose regimen for the first episode was 3,440 (1,904-6,035) mg/m(2), and the median duration of the therapeutic regimen was 21 (9-48) weeks. The total duration and cumulative steroid dose were significantly higher in patients treated by pediatricians than in those treated by pediatric nephrologists (p = 0.001 and p = 0.008). Among the patient cohort, 55, 64 and 22 % received albumin infusions, diuretics and acetyl salicylic acid treatment, respectively, but the laboratory and clinical data did not differ between children treated or not treated with symptomatic drugs. Albumin and diuretic use did not vary between patients in pediatric units and those in pediatric nephrology units. This study shows major differences in steroid and symptomatic treatment of nephrotic syndrome by pediatricians and pediatric nephrologists. As these differences can influence the efficacy of the treatments and the appearance of side-effects, shared guidelines and their implementation through widespread educational activities are necessary.

Pediatric Cervical Spine Injuries: A Rare But Challenging Entity.

PubMed

Baumann, Florian; Ernstberger, Toni; Neumann, Carsten; Nerlich, Michael; Schroeder, Gregory D; Vaccaro, Alexander R; Loibl, Markus

2015-08-01

Injuries to the cervical spine in pediatric patients are uncommon. A missed injury can have devastating consequences in this age group. Because of the lack of routine in diagnosis and management of pediatric cervical spine injuries (PCSI), each of these cases represents a logistic and personal challenge. By means of clinical cases, we demonstrate key points in diagnostics and treatment of pediatric spine injuries. We highlight typical pediatric injury patterns and more adult-like injuries. The most common cause of injury is blunt trauma. There is an age-related pattern of injuries in pediatric patients. Children under the age of 8 frequently sustain ligamentous injuries in the upper cervical spine. After the age of 8, the biomechanics of the cervical spine are similar to adults, and therefore, bony injuries of the subaxial cervical spine are most likely to occur. Clinical presentation of PCSI is heterogeneous. Younger children can neither interpret nor communicate neurological abnormalities, which make timely and accurate diagnosis difficult. Plain radiographs are often misinterpreted. We find different types of injuries at different locations, because of different biomechanical properties of the immature spine. We outline that initial management is crucial for long-term outcome. Knowledge of biomechanical properties and radiographic presentation of the immature spine can improve the awareness for PCSI. Diagnosis and management of pediatric patients after neck trauma can be demanding. Level IV.

Few studies have examined distress in caregivers of pediatric cancer patients. We evaluated the association of socioeconomic, demographic, and patient clinical factors on caregivers' self-reported psychological distress associated with having a child with cancer. N = 366 pediatric cancer caregivers completed a self-administered questionnaire from July 2010 to July 2012. The Impact of Event Scale (IES), along with two subscales "intrusion" and "avoidance" measured caregiver cancer-specific distress, with higher scores indicating greater distress. Multivariable linear regression models were used to calculate coefficients (β) and 95 % confidence intervals (95 % CI) of IES by socioeconomic, demographic, and clinical factors. Average caregiver IES score was 31.2 (standard deviation (SD) = 16.9, range 0-75). Mean intrusion score was 18.1 (SD 9.8, range 0-35) and avoidance score was 12.8 (SD 9.0, range 0-40). Caregivers with household incomes <$40,000 reported higher mean distress scores than those with incomes ranging from $40,000 to $79,999 (β = 4.45, 95 % CI 0.04-8.87, p = 0.05). Infrequently or never attending religious services, younger child age, and a diagnosis of AML were associated with higher intrusion (all p < 0.05). Caregivers with a child currently receiving therapy reported higher overall IES (β = 5.9, 95 % CI 2.15-9.7, p < 0.01) and intrusion (β = 4.1, 95 % CI 1.9-6.3, p < 0.001) scores compared to those off therapy (β = 3.13, 95 % CI 0.93-5.33, p < 0.01). Our findings identify socioeconomic and clinical factors that influence psychological distress for caregivers of pediatric oncology patients. These findings underscore the importance of developing and testing interventions aimed at evaluating and addressing the psychosocial needs for high-risk caregivers in addition to those of patients.

Use of transesophageal Doppler ultrasonography in ventilated pediatric patients: derivation of cardiac output.

Tibby, S M; Hatherill, M; Murdoch, I A

To ascertain if cardiac output (CO) could be derived from blood flow velocity measured in the descending aorta of ventilated children by transesophageal Doppler ultrasonography (TED) without the need for direct aortic cross sectional area measurement, and to evaluate the ability of TED to follow changes in CO when compared with femoral artery thermodilution. Prospective, comparison study. A 16-bed pediatric intensive care unit of a university hospital. A total of 100 ventilated infants and children aged 4 days to 18 yrs (median age, 27 months). Diagnoses included postcardiac surgery (n = 58), sepsis/multiple organ failure (n = 32), respiratory disease (n = 5), and other (n = 5). A total of 55 patients were receiving inotropes or vasodilators. When patients were hemodynamically stable, a TED probe was placed into the distal esophagus to obtain optimal signal, and minute distance (MD) was recorded. Five consecutive MD measurements were made concurrently with five femoral artery thermodilution measurements, and the concurrent measurements were averaged. CO was then manipulated by fluid administration or inotrope adjustment, and the readings were repeated. Femoral artery thermodilution CO ranged from 0.32 to 9.19 L/min, (median, 2.46 L/min), and encompassed a wide range of high and low flow states. Theoretical consideration revealed the optimal TED estimate for CO to be (MD x patient height2 x 10(-7)). Linear regression analysis yielded a power function model such that: estimated CO = 1.158 x (MD x height2 x 10(-7))(0.785), r2 = 0.879, standard error of the estimate = 0.266. Inclusion of a correction factor for potential changes in aortic cross-sectional area with hypo- and hypertension did not appreciably improve the predictive value of the model. MD was able to follow percentage changes in CO, giving a mean bias of 0.87% (95% confidence interval -0.85% to 2.59%), and limits of agreement of +/- 16.82%. The median coefficient of variation for MD was 3.3%. TED provides a clinically accurate estimate of CO across the entire pediatric age range and is able to follow changes in CO.

Determination of the appropriate tracheal tube size using formulas based on age or height often is inaccurate in pediatric patients with congenital heart disease (CHD), particularly in those with high pulmonary arterial pressure (PAP). Here, the authors compared tracheal diameters between pediatric patients with CHD with high PAP and low PAP. Retrospective clinical study. Hospital. Pediatric patients, from birth to 6 months of age, requiring general anesthesia and tracheal intubation who underwent computed tomography were included. Patients with mean pulmonary artery pressure >25 mmHg were allocated to the high PAP group, and the remaining patients were allocated to the low PAP group. The primary outcome was the tracheal diameter at the cricoid cartilage level, and the secondary goal was to observe whether the size of the tracheal tube was appropriate compared with that obtained using predictable formulas based on age or height. The mean tracheal diameter was significantly larger in the high PAP group than in the low PAP group (p < 0.01). Pediatric patients with high PAP required a larger tracheal tube size than predicted by formulas based on age or height (p = 0.04 for age and height). Pediatric patients with high PAP had larger tracheal diameters than those with low PAP and required larger tracheal tubes compared with the size predicted using formulas based on age or height.

To summarize the clinical characteristics and outcomes of pediatric sports-related concussion (SRC) patients who were evaluated and managed at a multidisciplinary pediatric concussion program and examine the healthcare resources and personnel required to meet the needs of this patient population. We conducted a retrospective review of all pediatric SRC patients referred to the Pan Am Concussion Program from September 1st, 2013 to May 25th, 2015. Initial assessments and diagnoses were carried out by a single neurosurgeon. Return-to-Play decision-making was carried out by the multidisciplinary team. 604 patients, including 423 pediatric SRC patients were evaluated at the Pan Am Concussion Program during the study period. The mean age of study patients was 14.30 years (SD: 2.32, range 7-19 years); 252 (59.57%) were males. Hockey (182; 43.03%) and soccer (60; 14.18%) were the most commonly played sports at the time of injury. Overall, 294 (69.50%) of SRC patients met the clinical criteria for concussion recovery, while 75 (17.73%) were lost to follow-up, and 53 (12.53%) remained in active treatment at the end of the study period. The median duration of symptoms among the 261 acute SRC patients with complete follow-up was 23 days (IQR: 15, 36). Overall, 25.30% of pediatric SRC patients underwent at least one diagnostic imaging test and 32.62% received referral to another member of our multidisciplinary clinical team. Comprehensive care of pediatric SRC patients requires access to appropriate diagnostic resources and the multidisciplinary collaboration of experts with national and provincially-recognized training in TBI.

We quantified pyridoxal 5'-phosphate (PLP), pyridoxal (PL), and 4-pyridoxic acid (PA) in the cerebrospinal fluid (CSF) of children and to investigate the effect of age, sex, epilepsy, and anti-epileptic drug (AED) therapy on these vitamers. CSF samples prospectively collected from 116 pediatric patients were analyzed. PLP, PL, and PA were measured using high-performance liquid chromatography with fluorescence detection, using pre-column derivatization by semicarbazide. Effects of age, sex, epilepsy, and AEDs on these vitamers and the PLP/PL ratio were evaluated using multiple linear regression models. The PLP, PL, and PA concentrations were correlated negatively with age and the PLP/PL ratio was correlated positively with age. Multiple regression analysis revealed that the presence of epilepsy was associated with lower PLP concentrations and PLP/PL ratios but sex and AED therapy had no influence on these values. The observed ranges of these vitamers in epileptic and non-epileptic patients were demonstrated. We showed the age dependence of PLP and PL in CSF from pediatric patients. Epileptic patients had lower PLP concentrations and PLP/PL ratios than non-epileptic patients, but it is unknown whether this is the cause, or a result, of epilepsy. Copyright © 2016 Elsevier B.V.

2015-01-01

Psoriasis is a chronic, immune-mediated, inflammatory systemic disease which targets primarily the skin. It presents a genetic basis, affecting 1 to 3% of the white population. Nevertheless, the existence of two psoriasis incidence peaks has been suggested (one in adolescence before 20 years of age and another in adulthood) onset may occur at any age, including childhood and adolescence, in which its prevalence ranges between 0.7% and 1.2%. As for adult psoriasis, pediatric psoriasis has recently been associated with obesity, metabolic syndrome, increased waist circumference percentiles, and metabolic laboratory abnormalities, warranting early monitoring and lifestyle modifications. In addition, due to psoriasis chronic nature and frequently occurring relapses, psoriatic patients tend to have an impaired quality of life, often requiring long-term treatment. Therefore, education of both pediatric patients and their parents is essential to successful and safe disease management. However, systemic treatment of children is challenging as the absence of standardized guidelines and the fact that evidence-based data form randomized controlled trials are very limited. This review shows an overview of the current understanding of the pathogenesis, comorbidities, differential diagnosis, treatment and prevention of pediatric psoriasis, also presenting with an emphasis on the necessity of an integrated treatment approach involving different specialists such as dermatologist, pediatricians, rheumatologists, etc.

To study the independent determinants of graft survival among pediatric and adolescent live donor kidney transplant recipients. Between March 1976 and March 2004, 1600 live donor kidney transplants were carried out in our center. Of them 284 were 20 yr old or younger (mean age 13.1 yr, ranging from 5 to 20 yr). Evaluation of the possible variables that may affect graft survival were carried out using univariate and multivariate analyses. Studied factors included age, gender, relation between donor and recipient, original kidney disease, ABO blood group, pretransplant blood transfusion, human leukocyte antigen (HLA) matching, pretransplant dialysis, height standard deviation score (SDS), pretransplant hypertension, cold ischemia time, number of renal arteries, ureteral anastomosis, time to diuresis, time of transplantation, occurrence of acute tubular necrosis (ATN), primary and secondary immunosuppression, total dose of steroids in the first 3 months, development of acute rejection and post-transplant hypertension. Using univariate analysis, the significant predictors for graft survival were HLA matching, type of primary urinary recontinuity, time to diuresis, ATN, acute rejection and post-transplant hypertension. The multivariate analysis restricted the significance to acute rejection and post-transplant hypertension. The independent determinants of graft survival in live-donor pediatric and adolescent renal transplant recipients are acute rejection and post-transplant hypertension.

International guidelines indicate that children with profound hearing loss should receive a cochlear implant (CI) soon after diagnosis in order to optimize speech and language rehabilitation. Although prompt rehabilitation is encouraged by current guidelines, delays in cochlear implantation are still present. This study investigated whether European countries establish timely pediatric CI care based on epidemiological, commercial, and clinical data. An estimation of the number of pediatric CI candidates in European countries was performed and compared to epidemiological (Euro-CIU), commercial (Cochlear ® ), and clinical (institutional) age-at-implantation data. The ages at implantation of pediatric patients in eight countries (the Netherlands, Belgium, Germany, the United Kingdom, France, Turkey, Portugal, and Italy) between 2005 and 2015 were evaluated. From 2010 onwards, over 30% of the pediatric CI candidates were implanted before 24 months of age. Northern European institutions implanted children on average around 12 months of age, whereas southern European institutions implanted children after 18 months of age. The Netherlands and Germany implanted earliest (between 6 and 11 months). Implemented newborn hearing screening programs and reimbursement rates of CIs vary greatly within Europe due to local, social, financial, and political differences. However, internationally accepted recommendations are applicable to this heterogeneous European CI practice. Although consensus on early pediatric cochlear implantation exists, this study identified marked delays in European care. Regardless of the great heterogeneity in European practice, reasons for latency should be identified on a national level and possibilities to prevent avoidable future implantation delays should be explored to provide national recommendations.

Refractory status epilepticus carries significant morbidity and mortality. Recent reports have promoted the use of the ketogenic diet as an effective treatment for refractory status epilepticus. We describe our recent experience with instituting the ketogenic diet for 4 critically ill children in refractory status epilepticus, ranging in age from 9 weeks to 13.5 years after failure of traditional treatment. The ketogenic diet allowed these patients to be weaned off continuous infusions of anesthetics without recurrence of status epilepticus, though delayed ketosis and persistently elevated glucose measurements posed special challenges to effective initiation, and none experienced complete seizure cessation. The ease of sustaining myocardial function with fatty acid energy substrates compares favorably over the myocardial toxicity posed by anesthetic doses of barbiturates and contributes to the safety profile of the ketogenic diet. The ketogenic diet can be implemented successfully and safely for the treatment of refractory status epilepticus in pediatric patients. © The Author(s) 2014.

To examine the characteristics of pediatric trials conducted under US legislation and to compare results with data from 2002 to 2007. We reviewed all pediatric trials provided to the US Food and Drug Administration in submissions that were approved between September 28, 2007 and December 21, 2010. We extracted data for each trial including age range, therapeutic indication, design, duration, and patient and center enrollment by location. Overall 346 studies on 113 drugs and biologicals enrolled 55 819 pediatric patients. The United States participated in 86% of the studies, providing 71% of the centers and 74% of the patients. Corresponding percentages for non-US countries were 43%, 29%, and 26% respectively. Developing or transition countries participated in 22% of the studies, providing 12% of the centers and 10% of the patients; our earlier analysis found corresponding percentages of 38%, 12%, and 23%. The most common therapeutic areas studied in the latter countries were infectious, neurologic, and pulmonary diseases. Seventy-eight vaccine studies enrolled 147 692 patients. The United States participated in 40% of the studies, providing 39% of the centers and 22% of the patients. Corresponding percentages for non-US countries were 74%, 61%, and 78% respectively. Developing or transition countries participated in 27% of the studies, providing 15% of the centers and 52% of the patients. The United States remains an important location for pediatric trials. Developing country involvement in pediatric drug development is not increasing, although these countries participate significantly in vaccine trials.

To compare chiropractic students' perceptions of preparedness for practice before and after a clinical placement in Rarotonga and to report demographics from these experiences. The students completed deidentified pre- and postplacement surveys assessing pediatric practice preparedness. Students tallied the patient numbers, age, and chiropractic techniques used per visit for each day of clinic placement. On completion of the program, participating students (27/34, or 79% of the student cohort) did a postplacement survey on their perception of practice preparedness. Data were analyzed with the Spearman rho correlation, the Mann-Whitney U test, and regression analysis. There was an increase in perceived preparedness for pediatric practice, ranging from 24.1% of the student cohort at the start of the study to 82.1% following clinical placement in Rarotonga. The change in student preparedness to practice with children was positively correlated with the total number of children managed (r s = .05, p = .01) and the number of children managed who were under 10 years of age (r s = .60, p = .001). Multiple regression analysis demonstrated a medium positive effect for postprogram preparedness (F [4, 20] = 3.567, p = .024). Clinical outreach to Rarotonga provided a broad case mix of patients and a change in student perceptions of preparedness to practice with children, which was positively affected by the total number of children managed and the number of children managed who were under 10 years of age.

To examine issues regarding the granularity (size/scale) and potential acceptability of recommendations in a ventilator management protocol for children with pediatric acute respiratory distress syndrome. Survey/questionnaire. The eight PICUs in the Collaborative Pediatric Critical Care Research Network. One hundred twenty-two physicians (attendings and fellows). None. We used an online questionnaire to examine attitudes and assessed recommendations with 50 clinical scenarios. Overall 80% of scenario recommendations were accepted. Acceptance did not vary by provider characteristics but did vary by ventilator mode (high-frequency oscillatory ventilation 83%, pressure-regulated volume control 82%, pressure control 75%; p = 0.002) and variable adjusted (ranging from 88% for peak inspiratory pressure and 86% for FIO2 changes to 69% for positive end-expiratory pressure changes). Acceptance did not vary based on child size/age. There was a preference for smaller positive end-expiratory pressure changes but no clear granularity preference for other variables. Although overall acceptance rate for scenarios was good, there was little consensus regarding the size/scale of ventilator setting changes for children with pediatric acute respiratory distress syndrome. An acceptable protocol could support robust evaluation of ventilator management strategies. Further studies are needed to determine if adherence to an explicit protocol leads to better outcomes.

Donors are matched for weight in pediatric heart transplantation (PHT), yet age differences are not considered in this decision. In this study we attempt to identify the effect of age differences in weight-matched patients and the effect these differences have on post-transplant survival. The United Network of Organ Sharing (UNOS) database was queried for the period from October 1987 to March 2014 for all pediatric heart transplant patients. Transplants with donor-to-recipient (D-R) weight ratios of 0.8 to 1.5 were identified (weight-matched). D-R age differences were categorized as: donors 5 years younger than recipients (DR+5). A total of 4,408 patients were identified as weight-matched transplants. Of these transplants, 681 were D>R+5, 3,596 were D=R±5 and 131 were DR+5 transplants were found to be associated with decreased post-transplant survival compared with D=R±5 (p = 0.002). Rates of acute rejection were similar among all groups but post-transplant coronary allograft vasculopathy (CAV) was more prevalent in D>R+5 than D=R±5 patients (28% and 18%, respectively; p < 0.001). Increasing age difference by each year was associated with decreasing median post-transplant survival time (p < 0.001; hazard ratio 1.018, range 1.011 to 1.025). The overall negative association with mortality was due to the adolescent cohort (11 to 17 years), specifically D>R+5 transplants, utilizing organs from donors >25 of age. In PHT, increasing D-R age difference decreases survival; however, this effect is driven by recipients 11 to 17 years old and donors >25 years old. Allocation of younger donor organs to adolescent recipients should be a priority. Copyright © 2017 International Society for Heart and Lung Transplantation. Published by Elsevier Inc.

To determine the stated art preferences of pediatric patients through an art survey and determine whether preferences vary, with different age groups associated with different stages of cognitive development. Exposure to visual art has been shown to have an impact on improved health and satisfaction outcomes. However, there is little literature on the effect of art on pediatric patients. While designing pediatric wards, a common assumption is to use fantasy and Disney-like themes; but research across all age groups on whether children prefer these themes is limited. A survey including 20 images with a variety of subject matter and styles was administered to 64 pediatric inpatients (ages 5-17) at Memorial Hermann Hospital in Houston, TX. Children were asked to rate the selection of, and their emotional response to, the images in the survey. Qualitative comments were recorded. Results were analyzed for each of the three age groups (5-6, 7-10, and 11-17 years) according to Piaget's developmental stages, as well as across all age groups. There were significant differences in art preferences across the different age groups, especially with respect to child art (art created by children). Overall, the results for 5-10-year-olds were more significant than those for 11-17-year-olds (adolescents). Nature elements were preferred across all age groups, but all nature images were not rated similarly. Images that were bright and colorful were rated better than images that were pale. The presence of a strong context that children could associate with was a defining feature of preferred images. Content drove preference more than style, though color was a key determinant. Comments on the artwork tended to be more objective/absolute for the youngest patients and more subjective/relative for the oldest. The combination of bright colors, engaging themes, and nature content is consistently highly rated by pediatric patients. However, pediatric preferences vary significantly among the three operational stages, so one should be careful before using the "one-size-fits-all" approach. Child art, typically used in pediatric wards, is better suited for younger children than for older children.

Acute pediatric encephalitis with fulminant cerebral edema can rapidly become fatal or result in devastating neurological sequelae. All cases coded with the discharge diagnosis of acute encephalitis between January 2000 and December 2010 were reviewed. Of the 1038 children with acute pediatric encephalitis, 25 were enrolled in our study with ages ranging from 5 months to 16 years. The major neurological symptoms included an altered level of consciousness (72%), vomiting (60%), and headache (48%). The onset of neurological symptoms to signs of brain herniation ranged from 0 days to 9 days. Nineteen (76%) patients had a seizure 24-48 hours prior to showing signs of fulminant cerebral edema, and 12 (48%) patients developed status epilepticus. Sixteen patients died, and no survivors returned to baseline. Risk factors for seizures and status epilepticus were compared between the fulminant cerebral edema group (n = 25, 19 seizures, including 12 status epilepticus) and control group (nonfulminant cerebral edema) (n = 1013, 444 seizures, including 141 status epilepticus; p = 0.001 for seizures and p < 0.001 for status epilepticus). Our findings indicate that preceding seizures and status epilepticus are significant risk factors for fulminant cerebral edema in children with acute encephalitis. Copyright © 2016.

Formulation approaches to pediatric oral drug delivery: benefits and limitations of current platforms

PubMed Central

Lopez, Felipe L; Ernest, Terry B; Tuleu, Catherine; Gul, Mine Orlu

2015-01-01

Introduction: Most conventional drug delivery systems are not acceptable for pediatric patients as they differ in their developmental status and dosing requirements from other subsets of the population. Technology platforms are required to aid the development of age-appropriate medicines to maximize patient acceptability while maintaining safety, efficacy, accessibility and affordability. Areas covered: The current approaches and novel developments in the field of age-appropriate drug delivery for pediatric patients are critically discussed including patient-centric formulations, administration devices and packaging systems. Expert opinion: Despite the incentives provided by recent regulatory modifications and the efforts of formulation scientists, there is still a need for implementation of pharmaceutical technologies that enable the manufacture of licensed age-appropriate formulations. Harmonization of endeavors from regulators, industry and academia by sharing learning associated with data obtained from pediatric investigation plans, product development pathways and scientific projects would be the way forward to speed up bench-to-market age appropriate formulation development. A collaborative approach will benefit not only pediatrics, but other patient populations such as geriatrics would also benefit from an accelerated patient-centric approach to drug delivery.

The conjunctival microcirculation in 14 pediatric and 8 adult sickle cell anemia (SCA) patients was studied using computer-assisted intravital microscopy. The bulbar conjunctiva in SCA patients in both age groups exhibited a blanched/avascular appearance characterized by decreased vascularity. SCA patients from both age groups had many of the same abnormal morphometric {vessel diameter, vessel distribution, morphometry (shape), tortuosity, arteriole:venule (A:V) ratio, and hemosiderin deposits} and dynamic {vessel sludging/sludged flow, boxcar blood (trickled) flow and abnormal flow velocity} abnormalities. A severity index (SI) was computed to quantify the degree of vasculopathy for comparison between groups. The severity of vasculopathy differed significantly between the pediatric and adult patients (SI: 4.2 ± 1.8 vs 6.6 ± 2.4; p=0.028), indicative of a lesser degree of overall severity in the pediatric patients. Specific abnormalities that were less prominent in the pediatric patients included abnormal vessel morphometry and tortuosity. Sludged flow, abnormal vessel distribution, abnormal A:V ratio, and boxcar flow, appeared in high prevalence in both age groups. The results indicate that SCA microvascular abnormalities develop in childhood and the severity of vasculopathy likely progresses with age. Intervention and effective treatment/management modalities should target pediatric patients to ameliorate, slow down or prevent progressive microvascular deterioration. PMID:20872552

Recent OPTN bylaw revisions mandate US transplant programs have an "approved pediatric component" in order to perform heart transplantation (HT) in patients <18 years old. The impact of this change on adolescents, a group known to be at high-risk for graft loss and nonadherence, is unknown. We studied all US pediatric (age <18 years) HT from 2000-2015 to compare graft survival between centers organized primarily for adult versus pediatric care. Centers were designated as pediatric- or adult-specialty care according to the ratio of pediatric:adult HT performed and minimum age of HT (pediatric-specialty defined as ratio>0.7; adult-specialty ratio<0.05 and minimum age >8 years). In propensity score-matched cohorts we observed no difference in graft loss by center type (median survival: adult 12.4 vs. pediatric 9.2 years, p=0.174). Compared to the matched pediatric cohort, adult-specialty center recipients lived closer to their transplant center (31 vs. 45 miles, p=0.012), and trended toward fewer out-of-state transplants (15 vs. 25%, p=0.082). Our data suggest that select adolescents can achieve similar mid-term graft survival at centers organized primary for adult HT care. Regardless of post-HT setting, the development of care models that demonstrably improve adherence, may be of greatest benefit to improving survival of this high-risk population.

The aim of the study was to review a single institution experience of minimally invasive Heller's myotomy in pediatric patients with achalasia. An institutional review board-approved retrospective review from 1999 to 2005 identified patients 18 years old and younger who underwent a minimally invasive Heller's myotomy for achalasia. Twenty-six patients were identified with a mean age of 15 (range, 4-18 years). There were 11 female and 15 male patients. There were 3 intraoperative complications (2 esophageal mucosal injuries and 1 aspiration). There was no mortality. All 26 surgeries were completed laparoscopically. Two patients had Dor fundoplication, whereas 23 patients had Toupet fundoplication. Average length of hospital stay was 2.7 days (range, 1-4 days) excluding the 3 patients with intraoperative complications and 3.5 days for all patients (range, 1-17 days). Postoperative follow-up ranged from 0 to 75 months (mean, 20 months). Postoperatively, one patient developed reflux symptoms (incidence 4%). Seven patients (27%) had recurrence of symptoms at a mean of 13 months (range, 1-66 months) after their operation. Laparoscopic Heller's myotomy with fundoplication is a safe and effective treatment of symptomatic achalasia in the pediatric population. Complications were low in this group of patients and comparable to other published reports in the literature.

Community-acquired pneumonia (CAP) is a both common and serious childhood infection. Antibiotic treatment guidelines help to reduce inadequate antibiotics prescriptions. We conducted a retrospective study at the Clinical Emergency Hospital for Children, 3rd Pediatric Clinic, Cluj-Napoca and Dr. Gavril Curteanu Clinical City Hospital, in Oradea. All patients discharged with a diagnosis of CAP between December 1, 2014 and February 28, 2015, were included in the study. There were 146 cases discharged with pneumonia in Cluj-Napoca center (mean age 4 years; range: 1 month - 16 years), and 212 cases in Oradea center (mean age 0.9 years; range: 2 weeks - 8 years). All cases were analyzed. The analysis made in Clinical Emergency Hospital for Children, 3rd Pediatric Clinic, Cluj-Napoca, showed that the antibiotics used in children hospitalized with community-acquired CAP are cefuroxime (43%), ceftriaxone (23%), macrolides (16%), ampicillin in association with an aminoglycoside (6%) and other antibiotics. The same antibiotics were used in Dr. Gavril Curteanu Clinical City Hospital of Oradea, where ampicillin in association with aminoglycoside was utilized in younger children (mean age 1.3 years), while ceftriaxone in older children (5.7 years) and children with high inflammation markers (ESR, CRP). From 11 pleurisy cases, 9 received cefuroxime or ceftriaxone. There was a wide variability in CAP antibiotic treatment across university hospitals, regarding antibiotic choice and dosing. Antibiotic selection was not always related to the clinical and laboratory characteristics of the patient. The national guideline was not followed, especially in children aged one to three months.

Incisional hernia (IH) is a recognized complication of open and laparoscopic visceral surgery, with reported rates of 10-50% in adult surgical literature. There is a paucity of data relating to incisional hernias in children. The aim of our study was to analyze the incidence and treatment of IH in children. Retrospective review of all patients admitted for incisional hernia repair at a tertiary pediatric surgical centre in the UK more than a 7-year period was performed. Data collected included age at initial surgery, time to IH repair, and type of IH repair and postoperative complications. Twenty one patients (14 male) underwent IH repair during the study period. The incidence of IH among children who had primary abdominal surgery in our institution less than the age of 6months was 2.3%. Median age at repair was 7.9months (range: 18days-5years). Median time from primary surgery to diagnosis of IH was 2months (range 0day-3years), with 81% (17/21) diagnosed within 1year of the preceding abdominal procedure. The most common pathology necessitating the primary operative procedure was necrotising enterocolitis (n=9) in babies of gestational age less than 30weeks. The highest rates of IH were noted in infants following closure of stoma (7.5%) and pyloromyotomy (2.52%). Primary closure was undertaken in all cases. Two children had recurrence of IH, one of which underwent surgical repair. Incidence of IH in children is low but significant. IH was most commonly diagnosed following closure of stoma for NEC in this study. Copyright © 2016. Published by Elsevier Inc.

2015-01-01

Mucoceles are common cystic lesions of the oral mucosa. Extravasation mucoceles (EMs) are mainly found in the lower lip of young patients, whereas retention mucoceles (RMs) are usually located in the cheek or palate of older patients. This study was undertaken to more fully characterize the clinicopathologic features of mucoceles in pediatric patients. The records of 56 pediatric patients with mucoceles were included in the study. Age, sex, history of trauma, intraoral site, size, and method of treatment were evaluated. Histopathologically the lesions were classified as being EMs or RMs. The age range was 1.5 to 16 years (mean age 11.2 yrs). Of the 56 patients, 24 (43%) were males and 32 (57%) were females, with a male:female ratio of 1:1.33. A history of trauma was recorded in 32 (57%) patients of the lower lip. The intraoral sites were the lower lip (38 [68%]), tongue (10 [18%]), and floor of the mouth (8 [14%]). Of the 56 patients, 44 (79%) were EM and 12 (21%) were ranulas. No RMs were found. Mucoceles ranged from 0.3 to 3.8 cm in diameter (mean 0.9 cm). The treatment of EMs was surgical excision. Cryosurgey, electrosurgery, and carbon dioxide laser were also used. In contrast to adults, where EM and RM types can be found, among children all cases are of the EM type. The disparate site and age incidences of EMs and RMs of the oral mucosa suggest that these two types are not related and possibly have a different etiopathogenesis. © 2015 Wiley Periodicals, Inc.

To evaluate children's cardiovascular disease (CVD) risk factors as predictors of parents' subsequent CVD, type 2 diabetes mellitus (T2DM), and high blood pressure (HBP). We conducted a 26-year prospective follow-up of 852 5- to 19-year-old black and white schoolchildren (mean age, 12 years; Lipid Research Clinics, 1973-8), and parents (mean age, 40 years) from 519 families in Princeton Schools, Cincinnati, Ohio. Schoolchildren were reassessed in the Princeton Follow-up study 1999-2003 at mean age 39 years; CVD, T2DM, and HBP history of their 1038 parents were reassessed by mean age 66 years. We assessed relationships of childhood risk factors with parental CVD, T2DM, and HBP. Child-probands identified with triglyceride (TG) levels, blood pressure, low-density lipoprotein cholesterol levels, body mass index (BMI), and glucose level greater than and high-density lipoprotein cholesterol levels less than established cutoff points. Pediatric HBP (P=.006) and low high-density lipoprotein cholesterol (P=.018) were predictive of parental CVD at age ≤50 years. Pediatric HBP (P=.02) and high TG (P=.03) were predictive of parental CVD at age ≤60 years. Pediatric high TG (P=.009) and high low-density lipoprotein cholesterol (P=.04) were predictive of parental CVD by age 66 years. Pediatric high BMI (P=.0006) were predictive of parental T2DM. Pediatric high BMI (P=.003) and black race (P=.004) were predictive of parental HBP. Pediatric risk factors identify families with parents at increased risk for CVD, T2DM, and HBP, emphasizing the usefulness of the child as proband. Copyright © 2012 Mosby, Inc. All rights reserved.

Medical clowns (MC) have become an integral part of the pediatric staff of hospital wards. While several studies have demonstrated the huge benefits of MC, there are almost no data regarding fear of clowns, a known phenomenon that means an irrational fear of clowns. In the current study, we sought to examine the prevalence of fear of clowns in pediatrics wards, and to characterize the affected children. The clinical work of three certified MCs was prospectively assessed. Every child with fear of clowns was noted, data were retrieved from the medical records, and the parents/child completed a specific questionnaire with a research assistant. Fear of clowns was defined as crying, anxiety response or effort to avoid contact with the MCs in small children, while in older children, it was determined if the child either reported fear of MCs or made actions to avoid clowns' intervention. A total of 1160 children participated in the study. All were hospitalized in the department of pediatrics or the pediatric emergency medicine department at Carmel Medical Center, and were exposed to a MC intervention session. Of the 1160 children, 14 children experienced fear of clowns (1.2%). The average age of children who experienced fear of clowns was 3.5 years (range 1-15). Interestingly, most of the children demonstrating fear of clowns were girls (12 out of 14, 85.7%). We found no association between fear of clowns and specific diagnosis, fever, clinical appearance, religion, or ethnicity. The prevalence of fear of clowns in the general pediatric hospitalized population was 1.2%, with a significant predominance of girls (85.7%). Children who experienced significant fear of clowns also experienced significant fear of encountering or thinking about a MC visit. Fear of clowns can affect children at any age (range 1-15), any ethnicity, religion, or degree of illness. Further large scale studies are required to better understand this unique phenomenon of fear of clowns. What is Known: • Fear of clowns is a phenomenon known for more than several decades and related to the increased use of clowns as negative characters in horror movies and TV shows. • The increased use of medical clowns in hospital wards and corridors increases the significance of defining and characterizing this phenomenon in hospital wards. What is New: • The study is novel by giving new data related to the extent of fear of clowns in pediatrics wards and giving demographic characteristic of children experiencing fear of clowns.

Multiples of Median-Transformed, Normalized Reference Ranges of Steroid Profiling Data Independent of Age, Sex, and Units.

The high complexity of pediatric reference ranges across age, sex, and units impairs clinical application and comparability of steroid hormone data, e.g., in congenital adrenal hyperplasia (CAH). We developed a multiples-of-median (MoM) normalization tool to overcome this major drawback in pediatric endocrinology. Liquid chromatography tandem mass spectrometry data comprising 10 steroid hormones representing 905 controls (555 males, 350 females, 0 to > 16 years) from 2 previous datasets were MoM transformed across age and sex. Twenty-three genetically proven CAH patients were included (21-hydroxylase deficiency [21OHD], n = 19; 11β-hydroxylase deficiency [11OHD], n = 4). MoM cutoffs for single steroids predicting 21OHD and 11OHD were computed and validated through new, independent patients (21OHD, n = 8; adrenal cortical carcinoma, n = 6; obesity, n = 40). 21OHD and 11OHD patients showed disease-typical, easily recognizable MoM patterns independent of age, sex, and concentration units. Two single-steroid cutoffs indicated 21OHD: 3.87 MoM for 17-hydroxyprogesterone (100% sensitivity and 98.83% specificity) and 12.28 MoM for 21-deoxycortisol (94.74% sensitivity and 100% specificity). A cutoff of 13.18 MoM for 11-deoxycortisol indicated 11OHD (100% sensitivity and 100% specificity). Age- and sex-independent MoMs are straightforward for a clinically relevant display of multi-steroid patterns. In addition, defined single-steroid MoMs can serve alone as predictors of 21OHD and 11OHD. Finally, MoM transformation offers substantial enhancement of routine and scientific steroid hormone data exchange due to improved comparability. © 2018 S. Karger AG, Basel.

Hip fracture registries offer an opportunity to identify and to monitor patients with rare conditions and outcomes, including hip fractures in pediatric patients. To report patient demographics and surgical outcomes of pediatric patients treated surgically for hip fractures in a large integrated health care system. Pediatric patients (< 21 years old at the time of fracture) with hip fractures were identified between 2009 and 2012 using our health care system's hip fracture registry. Patient characteristics, type of fracture, surgical treatment, and short-term complications. Among 39 patients identified, 31 (79.5%) were male, and the median age was 15 years old (interquartile range: 11-17 years). Most patients were Hispanic (n = 17, 43.6%) or white (n = 14, 35.9%). There were 8 patients (20.5%) with 15 comorbidities. Delbet Type IV (intertrochanteric) fractures were the most common fracture type (n = 22, 56.4%), and fixation method was equally distributed between intramedullary, screw and sideplate, and screws (n = 12, 30.8% for each). Most surgeries were performed by medium-volume surgeons (n = 22, 56.4%) at medium- and high-volume hospitals (n = 37, 94.9%). Three 90-day readmissions (7.7%), 1 infection (2.6%), 1 malunion (2.6%), and 1 revision (2.6%) were observed in this cohort during the study period. In our series using registry data, hip fractures younger than age 21 years were more common in boys and Hispanic patients. Intertrochanteric fractures (Delbet Type IV) were the most frequently observed type in our community-based hip fracture registry. Short-term complications were infrequent.

Health-Related Quality of Life (HRQOL) studies concerning children and adolescents are a growing field of research. The Pediatric Quality of Life Inventory (PedsQL) is considered as a promising HRQOL instrument with the availability of age appropriate versions and parallel forms for both child and parents. The purpose of the current study was to evaluate the psychometric properties of the Norwegian translation of the Pediatric Quality of Life Inventory (PedsQL) 4.0 generic core scale in a sample of healthy young adolescents. A cross-sectional study of 425 healthy young adolescents and 237 of their caregivers participating as a proxy. Reliability was assessed by Cronbach's alpha. Construct validity was assessed using exploratory factor analysis and by exploring the intercorrelations between and among the four PedsQL subscales for adolescents and their parents. All the self-report scales and proxy-report scales showed satisfactory reliability with Cronbach's alpha varying between 0.77 and 0.88. Factor analysis showed results comparable with the original version, except for the Physical Health scale. On average, monotrait-multimethod correlations were higher than multitrait-multimethod correlations. Sex differences were noted on the emotional functioning subscale, girls reported lower HRQOL than boys. The Norwegian PedsQL is a valid and reliable generic pediatric health-related Quality of Life measurement that can be recommended for self-reports and proxy-reports for children in the age groups ranging from 13-15 years.

Friedman tongue position: age distribution and relationship to sleep-disordered breathing.

Friedman tongue position (FTP) may play an important role in the evaluation of children with sleep-related breathing disorders (SRBD), but there are no previous data on FTP distribution by age. The objective of the current study was to determine the distribution of FTP by age and examine the relationship between FTP and snoring in children. Prospective cross-sectional study of 199 children (mean age, 6.8 years; 59% male) had tongue position assessed by FTP as part of their clinical examination of the oral cavity during routine ENT visits at a tertiary care children's hospital. The FTP and snoring frequency of participants was examined across the entire age range as well as by comparing those older (middle childhood and above) and younger than 5 years of age. Tongue position did not correlate with age or snoring frequency. The proportion of children with FTP III/IV was not significantly different in children younger than five years of age compared to older than five. Habitual snoring was not associated with having a higher FTP. Among children who snored <3 times per week, those who had previously undergone tonsillectomy did have higher FTP compared to those who had not (p=0.007). BMI-%-for-age was significantly correlated with FTP (p=0.003). The percent of children having FTP class III/IV differed significantly between ethnicities (22% of whites, 26% of others, 45% of hispanics, 53% of African-Americans; p=0.011). Inter-rater reliability among pediatric otolaryngologist was excellent (kappa=0.93, p<0.001). There does not appear to be an association between FTP with age or snoring frequency in children. The excellent inter-rater reliability for FTP among pediatric ENT providers suggests the null findings are not due to rater bias. These findings may serve as an important reference for those studying the role of tongue position in pediatric SRBD and complement previous studies examining FTP among children with known OSA or snoring.

The purpose of this study was to perform a systematic evaluation of morbidity and mortality in type B Niemann-Pick disease. A total of 103 patients with Niemann-Pick disease (49 males, 54 females, age range: 1-72 years) participated in natural history studies through Mount Sinai's International Center for Types A and B Niemann-Pick Disease between 1992 and 2012. Serious morbidities included significant neurological, hepatic, and cardiac disease. Thirteen patients had some degree of neurological impairment. Nine patients had cirrhosis or liver failure requiring transplantation. Coronary artery and valvular heart disease were present in nine patients. Of note, only four patients were oxygen dependent, although progressive pulmonary disease is a well-described feature of Niemann-Pick disease. During the follow-up period, 18 deaths occurred. The median age of death was 15.5 years (range 1-72). Causes of death included pneumonia, liver failure, and hemorrhage. The majority of deaths (12 of 18) occurred in patients <21 years, yielding a mortality rate of 19% in the pediatric population. This study demonstrates that Niemann-Pick disease is a life-threatening disorder with significant morbidity and mortality, especially in the pediatric population. The information collected in this series highlights the need for safe, effective therapy for Niemann-Pick disease.

BACKGROUND AND OBJECTIVES: Published data on oxidative stress in children with acute hepatitis A are still very scarce. This study aims to evaluate the oxidant/antioxidant status of these patients. DESIGN AND SETTING: Prospective, case-control study, over 2.5 years in patients under hospitalized and ambulatory care. PATIENTS AND METHODS: The levels of a whole-blood antioxidant, reduced glutathione; and plasma antioxidants, β-carotene, retinol, ascorbic acid, α-tocopherol; and the biomarker of oxidative stress, malondialdehyde, were evaluated in 50 pediatric patients (age range, 5-16 years; 29 males and 21 females) with acute hepatitis A and in 50 healthy children as control subjects (age range, 5-16 years; 25 males and 25 females). RESULTS: Plasma levels of reduced glutathione, β-carotene, retinol, α-tocopherol and ascorbic acid were significantly lower, while malondialdehyde plasma levels were significantly increased in the patient group when compared to the controls (P<.0001 for all parameters). CONCLUSIONS: Our findings show that pediatric patients with acute hepatitis A were influenced by oxidative stress, resulting in significantly lower levels of plasma antioxidants and increased lipid peroxidation. In the absence of other therapeutic options, antioxidant vitamin supplements could be added to the therapy for these patients to help reestablish the oxidant status balance. Further investigations to confirm this suggestion are recommended. PMID:21623054

Gamma Knife (GK) radiosurgery for pediatric arteriovenous malformations (AVM) of the brain presents a non-invasive treatment option. We report our institutional experience with GK for pediatric AVMs. We performed a retrospective review of all pediatric patients treated with GK for cerebral AVMs at our institution from November 2003 up to and including September 2014. Patient demographics, AVM characteristics, treatment parameters and AVM responses were recorded. Nineteen patients were treated, with 4 lost to follow-up. The mean age was 14.2 years (range. 7-18 years), with 10 being males (52.6%). The mean AVM diameter and volume were 2.68 cm and 3.10 cm3 respectively. The mean Spetzler-Martin (SM) and Pollock grades of the treated AVMs were 2.4 and 0.99 respectively. The mean follow-up was 62 months. All AVMs treated demonstrated a response on follow-up imaging. Nine of 15 (60.0%) patients displayed obliteration of their AVMs. Nine of 11 patients with a minimum of 3 years follow-up (81.8%) displayed obliteration, with SM and Pollock grades correlating to the chance of obliteration in this group. Two patients developed post-GK edema requiring short course dexamethasone therapy. No other major complications occurred. No permanent complications occurred. GK radiosurgery for pediatric AVMs offers a safe and effective treatment option, with low permanent complication rates during early follow-up.

Information relating to the epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) among hospitalized pediatric patients is limited. This report describes results of national MRSA surveillance among Canadian hospitalized pediatric patients from 1995 to 2007. Surveillance was laboratory-based. Clinical and epidemiologic data were obtained by reviewing the medical records. Standardized definitions were used to determine MRSA infection. Isolates were characterized by pulsed-field gel electrophoresis, staphylococcal cassette chromosome mec typing and antimicrobial susceptibility testing. A total of 1262 pediatric patients were newly identified as MRSA positive from 1995 to 2007. Ages ranged from newborn to 17.9 years, 49% were infected with MRSA (51% colonized), skin and soft tissue infections accounted for the majority (59%) of MRSA infections and 57% were epidemiologically classified as community acquired (CA). The most common epidemic strain types isolated were CMRSA2/USA100/800, CMRSA10/USA300 and CMRSA7/USA400. Overall, MRSA rates per 10,000 patient days increased from 0.08 to 3.88. Since 2005, overall rates of CA-MRSA per 10,000 patient days have dramatically increased while healthcare-associated MRSA rates remained relatively stable. These data suggest that the increase in MRSA among hospitalized pediatric patients is largely driven by the emergence of CA-MRSA strains with skin and soft tissue infections representing the majority of MRSA infections.

The aim of this study was to analyze the postoperative progress and medical management in the Pediatric Intensive Care Unit (PICU) of patients that underwent bilateral lung transplant. From April 1997 to June 1998, 10 pediatric lung transplants were performed at the Hospital Reina Sofía (Córdoba, Spain). There were 4 males and 6 females (mean age 11.5 years, range 5 to 15 years). Indications for transplantation were cystic fibrosis (n = 9) and one pulmonary fibrosis secondary to viral infection. Before the transplant, two patients required mechanical ventilation for acute respiratory decompensation and one patient was ventilator-dependent. Immunosuppression consisted of corticosteroids, azathioprine and cyclosporine or tacrolimus. Post-transplantation management included early extubation, when possible, optimal fluid balance to prevent lung edema, low aggressive mechanical ventilation and adequate treatment of complications, such as rejection and infection. There were no peri-operative mortalities. The mean stay in the PICU was 28 days (median: 17 days) and the mean time on mechanical ventilation was 19 days (median: 5.5 days). The most frequent complications were rejection (n = 8), hyperglycemia (n = 6), renal failure (n = 4), arterial hypertension (n = 4) and respiratory infections (n = 3). There were no airway complications. Even if the post-operative period in pediatric lung transplant patients is difficult, the results have been good with an important improvement in the quality of life of these patients has been achieved.

Health-related quality of life (HRQOL) measurement has emerged as an important health outcome in clinical trials, clinical practice improvement strategies, and healthcare services research and evaluation. While pediatric patient self-report should be considered the standard for measuring perceived HRQOL, there are circumstances when children are too young, too cognitively impaired, too ill or fatigued to complete a HRQOL instrument, and reliable and valid parent proxy-report instruments are needed in such cases. Further, it is typically parents' perceptions of their children's HRQOL that influences healthcare utilization. Data from the PedsQL DatabaseSM were utilized to test the reliability and validity of parent proxy-report at the individual age subgroup level for ages 2-16 years as recommended by recent FDA guidelines. The sample analyzed represents parent proxy-report age data on 13,878 children ages 2 to 16 years from the PedsQL 4.0 Generic Core Scales DatabaseSM. Parents were recruited from general pediatric clinics, subspecialty clinics, and hospitals in which their children were being seen for well-child checks, mild acute illness, or chronic illness care (n = 3,718, 26.8%), and from a State Children's Health Insurance Program (SCHIP) in California (n = 10,160, 73.2%). The percentage of missing item responses for the parent proxy-report sample as a whole was 2.1%, supporting feasibility. The majority of the parent proxy-report scales across the age subgroups exceeded the minimum internal consistency reliability standard of 0.70 required for group comparisons, while the Total Scale Scores across the age subgroups approached or exceeded the reliability criterion of 0.90 recommended for analyzing individual patient scale scores. Construct validity was demonstrated utilizing the known groups approach. For each PedsQL scale and summary score, across age subgroups, healthy children demonstrated a statistically significant difference in HRQOL (better HRQOL) than children with a known chronic health condition, with most effect sizes in the medium to large effect size range. The results demonstrate the feasibility, reliability, and validity of parent proxy-report at the individual age subgroup for ages 2-16 years. These analyses are consistent with recent FDA guidelines which require instrument development and validation testing for children and adolescents within fairly narrow age groupings and which determine the lower age limit at which reliable and valid responses across age categories are achievable. Even as pediatric patient self-report is advocated, there remains a fundamental role for parent proxy-report in pediatric clinical trials and health services research.

Pediatric tracheotomy is a complex procedure with significant postoperative complications. Wound-related complications are increasingly reported and can have considerable impact on clinical course and health care costs to tracheotomy-dependent children. The primary objective of this study was to identify the type and rate of complications arising from pediatric tracheotomy. A retrospective review of medical records of 302 children who underwent tracheotomy between December 1, 2000, and February 28, 2014, at a tertiary care pediatric referral center. Records were reviewed for preoperative diagnoses, gestational age, age at tracheotomy, tracheotomy technique, and incidence of complication. Main outcome measures included incidence, type, and timing of complications. Secondary measures included medical diagnoses and surgical technique. Of the 302 children who underwent tracheotomy, the median (SD) age at time of tracheotomy was 5 months (64 months) and the range was birth to 21 years. The most frequent diagnosis associated with performance of a tracheotomy was ventilator-associated respiratory failure (61.9%), followed by airway anomaly or underdevelopment (25.2%), such as subglottic or tracheal stenosis, laryngotracheomalacia, or bronchopulmonary dysplasia. The remaining indications for tracheotomy included airway obstruction (11.6% [35 of 302]) and vocal fold dysfunction (1.3% [4 of 302]). No statistical significance was found associated with diagnosis and incidence of complications. Sixty children (19.9%) had a tracheotomy-related complication. Major complications, such as accidental decannulation (1.0% [3 of 302]). There were no deaths associated with tracheotomy. Minor complications, such as peristomal wound breakdown or granuloma (12.9% [39 of 302]) and bleeding from stoma (1.7% [5 of 302]), were more common. Of all complications, 70% (42 of 60) occurred early (≤7 days postoperatively) and 20% (12 of 60) were late (>7 days postoperatively). Pediatric tracheotomy at our institution is associated with an overall 19.9% incidence of complications. Although the rate of major complications such as accidental decannulation or death is low, rates of peristomal skin breakdown and development of granuloma are more frequently reported and can occur at any point following tracheotomy. Further work is necessary to understand and mitigate wound care issues in post-tracheotomy care.

Vertigo and imbalance are often underestimated in the pediatric population, due to limited communication abilities, atypical symptoms, and relatively quick adaptation and compensation in children. Moreover, examination and interpretation of vestibular tests are very challenging, because of difficulties with cooperation and maintenance of alertness, and because of the sometimes nauseatic reactions. Therefore, it is of great importance for each vestibular laboratory to implement a child-friendly test protocol with age-appropriate normative data. Because of the often masked appearance of vestibular problems in young children, the vestibular organ should be routinely examined in high-risk pediatric groups, such as children with a hearing impairment. Purposes of the present study were (1) to determine age-appropriate normative data for two child-friendly vestibular laboratory techniques (rotatory and collic vestibular evoked myogenic potential [cVEMP] test) in a group of children without auditory or vestibular complaints, and (2) to examine vestibular function in a group of children presenting with bilateral hearing impairment. Forty-eight typically developing children (mean age 8 years 0 months; range: 4 years 1 month to 12 years 11 months) without any auditory or vestibular complaints as well as 39 children (mean age 7 years 8 months; range: 3 years 8 months to 12 years 10 months) with a bilateral sensorineural hearing loss were included in this study. All children underwent three sinusoidal rotations (0.01, 0.05, and 0.1 Hz at 50 degrees/s) and bilateral cVEMP testing. No significant age differences were found for the rotatory test, whereas a significant increase of N1 latency and a significant threshold decrease was noticeable for the cVEMP, resulting in age-appropriate normative data. Hearing-impaired children demonstrated significantly lower gain values at the 0.01 Hz rotation and a larger percentage of absent cVEMP responses compared with normal-hearing children. Seventy-four percent of hearing-impaired children showed some type of vestibular abnormality when examined with a combination of rotatory and cVEMP testing, in contrast to an abnormality rate of 60% with cVEMP and a rate of 49% with rotatory testing alone. The observed pediatric age correlations underscore the necessity of age-appropriate normative data to guarantee accurate interpretation of test results. The high percentages of abnormal vestibular test results in hearing-impaired children emphasize the importance of vestibular assessment in these children because the integrity of the vestibular system is a critical factor for motor and psychological development.

Among pediatric injury, brain injury is a leading cause of death and disability. To improve outcomes, many developed countries built neurotrauma databank (NTDB) system but there was not established nationwide coverage NTDB until 2009 and there have been few studies on pediatric traumatic head injury (THI) patients in Korea. Therefore, we analyzed epidemiology and outcome from the big data of pediatric THI. We collected data on pediatric patients from 23 university hospitals including 9 regional trauma centers from 2010 to 2014 and analyzed their clinical factors (sex, age, initial Glasgow coma scale, cause and mechanism of head injury, presence of surgery). Among all the 2617 THI patients, total number of pediatric patients was 256. The average age of the subjects was 9.07 (standard deviation±6.3) years old. The male-to female ratio was 1.87 to 1 and male dominance increases with age. The most common cause for trauma were falls and traffic accidents. Age ( p =0.007), surgery ( p <0.001), mechanism of trauma ( p =0.016), subdural hemorrhage (SDH) ( p <0.001), diffuse axonal injury (DAI) ( p <0.001) were statistically significant associated with severe brain injury. Falls were the most common cause of trauma, and age, surgery, mechanism of trauma, SDH, DAI increased with injury severity. There is a critical need for effective fall and traffic accidents prevention strategies for children, and we should give attention to these predicting factors for more effective care.

OBJECTIVES Identify risk factors for venous thromboembolism (VTE) and develop a VTE risk assessment model for pediatric trauma patients. DESIGN, SETTING, AND PATIENTS We performed a retrospective review of patients 21 years and younger who were hospitalized following traumatic injuries at the John Hopkins level 1 adult and pediatric trauma center (1987-2011). The clinical characteristics of patients with and without VTE were compared, and multivariable logistic regression analysis was used to identify independent risk factors for VTE. Weighted risk assessment scoring systems were developed based on these and previously identified factors from patients in the National Trauma Data Bank (NTDB 2008-2010); the scoring systems were validated in this cohort from Johns Hopkins as well as a cohort of pediatric admissions from the NTDB (2011-2012). MAIN RESULTS Forty-nine of 17,366 pediatric trauma patients (0.28%) were diagnosed with VTE after admission to our trauma center. After adjusting for potential confounders, VTE was independently associated with older age, surgery, blood transfusion, higher Injury Severity Score (ISS), and lower Glasgow Coma Scale (GCS) score. These and additional factors were identified in 402,329 pediatric patients from the NTDB from 2008-2010; independent risk factors from the logistic regression analysis of this NTDB cohort were selected and incorporated into weighted risk assessment scoring systems. Two models were developed and were cross-validated in 2 separate pediatric trauma cohorts: 1) 282,535 patients in the NTDB from 2011 to 2012 2) 17,366 patients from Johns Hopkins. The receiver operator curve using these models in the validation cohorts had area under the curves that ranged 90% to 94%. CONCLUSIONS VTE is infrequent after trauma in pediatric patients. We developed weighted scoring systems to stratify pediatric trauma patients at risk for VTE. These systems may have potential to guide risk-appropriate VTE prophylaxis in children after trauma.

Introduction Topical benzocaine is a local anesthetic commonly used to relieve pain caused by teething, periodontal irritation, burns, wounds, and insect bites. Oral preparations may contain benzocaine concentrations ranging from 7.5% to 20%. Pediatric exposure to such large concentrations may result in methemoglobinemia and secondarily cause anemia, cyanosis, and hypoxia. Methods This is a retrospective study of exposures reported to a statewide poison control system. The electronic health records were queried for pediatric exposures to topical benzocaine treated at a healthcare facility from 2004 to 2014. Cases of benzocaine exposure were reviewed for demographic and clinical information, and descriptive statistical analysis was performed. Results The query resulted in 157 cases; 58 were excluded due to co-ingestants, or miscoding of non-benzocaine exposures. Children four years of age and younger represented the majority of cases (93%) with a median age of 1 year. There were 88 cases of accidental/ exploratory exposure, while 6 cases resulted from therapeutic application or error, 4 cases from adverse reactions, and 1 case from an unknown cause. Asymptomatic children accounted for 75.5% of cases, but major clinical effects were observed in 5 patients. Those with serious effects were exposed to a range of benzocaine concentrations (7.5–20%), with 4 cases reporting methemoglobin levels between 20.2%–55%. Methylene blue was administered in 4 of the cases exhibiting major effects. Conclusion The majority of exposures were accidental ingestions by young children. Most exposures resulted in minor to no effects. However, some patients required treatment with methylene blue and admission to a critical care unit. Therapeutic application by parents or caregivers may lead to adverse effects from these commonly available products. PMID:28874945

Background In adults with heart failure, elevated levels of fibroblast growth factor 23 (FGF23) are associated with mortality. Data on FGF23 levels in pediatric heart failure are lacking. Patients and Methods We conducted a cross-sectional study of 17 healthy children (mean age, 13 years) and 20 pediatric patients with heart failure (mean age, 12 years) who underwent echocardiography and the following measurements: plasma FGF23 and parathyroid hormone (PTH); serum phosphate, creatinine and N-terminal prohormone brain natriuretic peptide (NT-proBNP). Symptom severity was assessed with the New York Heart Association (NYHA) and the Ross classification systems. Results Of 20 patients, 11 had dilated cardiomyopathy; 4, congenital heart disease; 3, hypertrophic cardiomyopathy; 1, a failing heart transplant; and 1, pulmonary hypertension. Mean phosphate levels in patients were within the reported reference range for healthy children. Median PTH levels were in the normal range in patients and controls. The median FGF23 level was higher in patients vs. controls (110.9 vs. 66.4 RU/ml, P=0.03) and higher in patients on diuretics vs. other patients (222.4 vs. 82.1 RU/ml, P=0.01). Levels of FGF23 and NT-proBNP were directly correlated (r=0.47, P=0.04), and patients with greater physical functional impairment had higher FGF23 levels (142.5 in those with moderate-severe limitation vs. 92.8 RU/ml in those with no limitation; P=0.05). Among patients with dilated cardiomyopathy, higher FGF23 levels were associated with a greater left ventricular end-diastolic diameter (r=0.63, P=0.04). Conclusion FGF23 levels are elevated in children with heart failure and are associated with diuretic use, severity of heart failure and left ventricular dilation. PMID:23740037

Metabolic syndrome (MetS), a cluster of cardiovascular risk factors, is one of the most common metabolic disorders, which lead to many chronic diseases. The link between childhood MetS and occurrence of atherosclerosis and its sequels in adulthood is well documented. This study aims to systematically review the prevalence of MetS among Iranian children and adolescents. An electronic search was conducted on studies published from January 1990 to January 2015. The main international electronic data sources were PubMed and the NLM Gateway (for MEDLINE), Institute of Scientific Information (ISI), and SCOPUS. For Persian databases, we used domestic databases. We included all available population-based studies and national surveys conducted in the pediatric age group aged 3-21-year-old. In this review, 2138 articles were identified (PubMed: 265; SCOPUS: 368; ISI: 465; Scientific Information Database: 189; IranMedex: 851; Irandoc: 46). After quality assessment, 13 qualified articles were evaluated. The number of total population and points of data were 24,772 and 125, respectively. Regarding the geographical distribution, we found 2 national, 6 provincial, and 5 district level points of data. The prevalence range of MetS among children was 1-22% using different definitions. Reported range of pediatric MetS defined by different criteria was as follows: National Cholesterol Education Program-Adult Treatment Panel III; 3-16%, International Diabetes Federation; 0-8%, American Heart Association; 4-9.5%, The National Health and Nutrition Examination Survey III; 1-18%, de Ferranti; 0-22%. MetS is a common metabolic disorder among Iranian children and adolescents, with increasing trends during the last decades. This finding provides baseline useful information for health policy makers to implement evidence based-health promotion for appropriate controlling of this growing health problem for the pediatric population.

To evaluate the clinical efficiency of transcatheter closure of atrial septal defect (ASD) with AGA-Amplatzer occlusion device in pediatric patients. Forty patients with ASD, 16 males, 24 females, at a mean age of 10.2 years (ranged from 3 to 15 years of age) and with a mean weight of 35.8 kg (ranged from 11 to 87 kg) were studied. Six cases were complicated with pulmonary stenosis (PS), 1 was complicated with ventricular tachycardia (VT). Right heart catheterizations were done in 40 patients for measuring the pressures of right ventricle and pulmonary artery. The balloon diameter of ASD was measured using balloon catheter with guiding wire. The diameter of ASD was measured by TTE and/or TEE, ascertaining the location and size of ASD. Amplatzer occlusion device was sized to be equal to or 1 - 2 mm more than the diameter of balloon stretched. All patients had successful implantation of the Amplatzer device. The success rate was 100%. The diameter measured by TTE was 7 - 30 mm (mean 17.12 mm). The diameter measured by TEE was 7 - 32 mm (mean 18.44 mm). The diameter of balloon stretched of ASD was 8 - 34 mm. Of the 40 cases, 6 were complicated with PS and accepted percutaneous balloon valvuloplasty (PBPV). One case was complicated with VT and accepted radiofrequency catheter ablation (RFCA). Neither complication nor residual shunt was found in any of the patients. The patients were recovered and followed up for 3 or 4 days after deployment of the Amplatzer device. Clinical symptom, cardiac murmur, and findings in ECG, echocardiography and X-ray were improved markedly. AGA-Amplatzer occlusion device is safe and efficient in pediatric patients with ASD.

Dissemination of pediatric basic life support (PBLS) skills is recommended. E-learning is accessible and cost-effective, but it is currently unknown whether laypersons can learn PBLS through e-learning. The hypothesis of this study was to investigate whether e-learning PBLS is non-inferior to instructor-led training. Participants were recruited among child-minders and parents of children aged 0-6 years. Participants were randomized to either 2-h instructor-led training or e-learning using an e-learning program (duration 17 min) including an inflatable manikin. After training, participants were assessed in a simulated pediatric cardiac arrest scenario. Tests were video recorded and PBLS skills were assessed independently by two assessors blinded to training method. Primary outcome was the pass rate of the PBLS test (≥8 of 15 skills adequately performed) with a pre-specified non-inferiority margin of 20%. In total 160 participants were randomized 1:1. E-learning was non-inferior to instructor-led training (difference in pass rate -4%; 95% CI -9:0.5). Pass rates were 100% among instructor-led trained (n=67) and 96% among e-learned (n=71). E-learners median time spent on the e-learning program was 30 min (range: 15-120 min) and the median number of log-ons was 2 (range: 1-5). After the study, all participants felt that their skills had improved. E-learning PBLS is non-inferior to instructor-led training among child-minders and parents with children aged 0-6 years, although the pass rate was 4% (95% CI -9:0.5) lower with e-learning.

This study sought to determine delta granule normal ranges for children and to validate methodology for the appropriate diagnosis of delta granule deficiency (storage pool disease) by using the whole-mount technique in electron microscopy. Specimens obtained from 40 healthy volunteers (2 months of age through 21 years old, 21 females and 19 males) were tested. Results showed dense granules/platelet (DG/Plt) ranged from 1.78 to 5.25. The 5th percentile was 1.96 DG/Plt with an overall mean ± SEM 3.07 ± 0.12 DG/Plt. In comparison, a previously published lower cutoff value, 3.68 DG/Plt, was significantly higher than the mean from our volunteers (P < 0.0001). We found no variability in dense granules/platelet based on race or sex and no significant variation by age subgroup. Pending wider studies, the value of 2 DG/Plt is a more appropriate lower limit of normal. In the absence of wider studies (in healthy volunteers and patients), laboratories should consider establishing their own reference ranges.

Bone marrow ABO incompatible transplantations require graft manipulation prior to infusion to avoid potentially lethal side effects. We analyzed the influence of pre-manipulation factors (temperature at arrival, transit time, time of storage at 4°C until processing and total time from collection to red blood cell depletion) on the graft quality of 21 red blood cell depletion procedures in ABO incompatible pediatric transplants. Bone marrow collections were processed using the Spectra Optia ® (Terumo BCT) automated device. Temperature at arrival ranged between 4°C and 6°C, median transit time was 9.75h (range 0.33-28), median time of storage at 4°-6°C until processing was 1.8h (range 0.41-18.41) and median time from collection to RBC depletion was 21h (range1-39.4). Median percentage of red blood cell depletion was 97.7 (range 95.4-98.5), median mononuclear cells recovery was 92.2% (range 40-121.2), median CD34+ cell recovery was 93% (range 69.9-161.2), median cell viability was 97.7% (range 94-99.3) and median volume reduction was 83.9% (range 82-92). Graft quality was not significantly different between BM units median age. Our preliminary data show that when all good manifacturing practices are respected the post-manipulation graft quality is excellent also for those units processed after 24h.

OBJECTIVE Penetrating brain injury in civilians is much less common than blunt brain injury but is more severe overall. Gunshot wounds (GSWs) cause high morbidity and mortality related to penetrating brain injury; however, there are few reports on the management and outcome of intracranial GSWs in children. The goals of this study were to identify clinical and radiological factors predictive for death in children and to externally validate a recently proposed pediatric prognostic scale. METHODS The authors conducted a retrospective review of penetrating, isolated GSWs sustained in children whose ages ranged from birth to 18 years and who were treated at 2 major metropolitan Level 1 trauma centers from 1996 through 2013. Several standard clinical, laboratory, and radiological factors were analyzed for their ability to predict death in these patients. The authors then applied the St. Louis Scale for Pediatric Gunshot Wounds to the Head, a scoring algorithm that was designed to provide rapid prognostic information for emergency management decisions. The scale's sensitivity, specificity, and positive and negative predictability were determined, with death as the primary outcome. RESULTS Seventy-one children (57 male, 14 female) had a mean age of 14 years (range 19 months to 18 years). Overall mortality among these children was 47.9%, with 81% of survivors attaining a favorable clinical outcome (Glasgow Outcome Scale score ≥ 4). A number of predictors of mortality were identified (all p < 0.05): 1) bilateral fixed pupils; 2) deep nuclear injury; 3) transventricular projectile trajectory; 4) bihemispheric injury; 5) injury to ≥ 3 lobes; 6) systolic blood pressure < 100 mm Hg; 7) anemia (hematocrit < 30%); 8) Glasgow Coma Scale score ≤ 5; and 9) a blood base deficit < -5 mEq/L. Patient age, when converted to a categorical variable (0-9 or 10-18 years), was not predictive. Based on data from the 71 patients in this study, the positive predictive value of the St. Louis scale in predicting death (score ≥ 5) was 78%. CONCLUSIONS This series of pediatric cranial GSWs underscores the importance of the initial clinical exam and CT studies along with adequate resuscitation to make the appropriate management decision(s). Based on our population, the St. Louis Scale seems to be more useful as a predictor of who will survive than who will succumb to their injury.

Extrapyramidal movement disorders associated with mitochondrial disease are difficult to treat and can lead to considerable disability. Moreover, potential new treatment trials on the horizon highlight the importance of genotype-phenotype associations and deep phenotyping of the movement disorders related to mitochondrial disease. To describe the phenotype, genetic etiology, and investigation of extrapyramidal movement disorders in a large and well-defined mitochondrial disease cohort. An observational cohort study at a single national referral center. Among 678 patients (87% adults) followed up at the Newcastle mitochondrial disease specialized referral center between January 1, 2000, and January 31, 2015, 42 patients (12 pediatric, 30 adult) with genetic or biochemical evidence of mitochondrial disease and with 1 or more predefined extrapyramidal movement disorders (parkinsonism, dystonia, tremor, chorea, and restless legs syndrome) were included. We investigated the prevalence and genetic causes of dystonia and parkinsonism as well as radiological findings in the context of movement disorders in mitochondrial disease. All patients were interviewed and examined. All available medical notes and clinical, radiological, and genetic investigations were reviewed. Forty-two patients (mean [SD] age, 37 [25] years; 38% female) with mitochondrial disease (12 pediatric [age range, 4-14 years], 30 adult [age range, 20-81 years]) with extrapyramidal movement disorders were identified. Dystonia manifested in 11 pediatric patients (92%), often in the context of Leigh syndrome; parkinsonism predominated in 13 adult patients (43%), among whom 5 (38%) harbored either dominant (n = 1) or recessive (n = 4) mutations in POLG. Eleven adult patients (37%) manifested with either generalized or multifocal dystonia related to mutations in mitochondrial DNA, among which the most common were the m.11778G>A mutation and mutations in MT-ATP6 (3 of 11 patients [27%] each). Bilateral basal ganglia lesions were the most common finding in brain magnetic resonance imaging, usually associated with generalized dystonia or Leigh syndrome. Dystonia, often associated with Leigh syndrome, was the most common extrapyramidal movement disorder among pediatric patients with mitochondrial disease. Parkinsonism was the most prevalent extrapyramidal movement disorder in adults and was commonly associated with POLG mutations; dystonia was predominantly associated with mitochondrial DNA mutations. These findings may help direct genetic screening in a busy neurology outpatient setting.

Although left ventricular (LV) mass may be important to judge effects of left-sided cardiac obstruction or hypertension, reproducible noninvasively determined normal data in the pediatric age group are scarce. To validate cross-sectional echocardiographic LV mass determination, our data were compared with LV mass assessed by magnetic resonance imaging (MRI). MRI was considered to be a good reference method because there is usually no problem in defining endo- and epicardial borders with MRI. LV mass was assessed in 14 children aged 5.3 years (10 days to 14.7 years) with a mean body surface area of 0.78 m2 (range 0.25 to 1.61). With cross-sectional echocardiography the epicardial and endocardial volumes were calculated using a Simpsons rule algorithm in the apical 2- and 4-chamber view. The difference between epi- and endocardial volumes was multiplied by 1.05 to yield the mass. Mass was assessed with MRI using a multislice technique; the area of each myocardial slice was calculated and multiplied with the slice thickness, and the resultant slice volumes were added to obtain the myocardial volume. On cross-sectional echocardiography, the mass was 55 g (range 12 to 126) or 64 g/m2 (range 46 to 79); on MRI it was 60 g (range 33 to 87) or 69 g/m2 (range 46 to 89). Regression analysis yielded an r value of 0.98 with a standard error of the estimate of 5.7 g or a 10% difference. In older children, LV mass determined by MRI was bigger than the one derived by echocardiography. It is concluded that cross-sectional echocardiography can reliably assess LV myocardial mass in pediatric patients.

Excisional surgery for choledochal malformations in Scotland is currently performed in three specialist pediatric surgical centers using open or laparoscopic-assisted techniques. We reviewed the outcome of children who had excisional surgery in Scotland between 1992 and 2010. Case notes for all patients undergoing excisional surgery in any of the three specialist pediatric surgical centers in Scotland between 1992 and 2010 were retrospectively reviewed. A total of 25 patients were identified, with a female preponderance of 4:1. Of these, three patients (12%) were diagnosed by antenatal ultrasound scan. The commonest presenting symptoms were anorexia (56%), abdominal pain (52%), and jaundice (52%). Only 20% had the classical triad of abdominal pain, jaundice, and a palpable mass. Using the King's College Hospital classification, 14 patients had type 1 malformations, 8 had type 4 malformations, and 3 had type 2 malformations. Median age at operation was 2 years (range 35 days to 13.5 years). Two centers performed open excision while the third center used primarily a laparoscopic-assisted technique. Median follow-up was 2.1 years (range 30 days to 11.9 years). Three patients (12%) required repeat laparotomy. The wound infection rate was 8% (n=2). The recurrent cholangitis rate was 8% (n=2). There was one late death due to adhesive small bowel obstruction, 4 years after surgery. To date, no patient has developed biliary tree stones or liver failure. Choledochal malformation excisional surgery, either open or laparoscopic assisted, can be safely performed in appropriately equipped, pediatric surgical centers in Scotland by experienced pediatric surgeons.

The ProSeal laryngeal mask airway (PLMA) has been available in pediatric sizes in the UK since 2007. Although several non-UK studies have evaluated PLMAs in children, there are little published data regarding their use in this country. Having decided to introduce the pediatric PLMA into our practice, we chose to prospectively audit the first 100 uses as part of our clinical governance. We studied children undergoing elective surgery who were considered suitable for a supraglottic airway. We recorded patient, surgical and insertion details, device performance data and complications. Patient management was not altered by inclusion in this audit. Twenty size 1.5, 55 size 2.0, 15 size 2.5 and 10 size 3.0 PLMAs were inserted in 100 consecutive children [median age 2 years (range 2 months to 10 years) and median weight 15 kg (range 4.9-60 kg)]. The overall first attempt success rate was 93% (size 1.5, 100%; size 2.0, 100%; size 2.5, 87%; size 3.0, 90%) and overall successful insertion rate was 99%. Median leak pressure was 25 cmH(2)O. Outright failure was seen in one patient; complications were seen in another six patients (partial airway obstruction in five patients and mild laryngospasm in one patient), all of whom were transient and none of whom required intubation. No episodes of regurgitation were recorded. Even without prior experience and using nonconventional insertion, pediatric PLMAs (including size 1.5) can be easily inserted and provide an effective airway.

Young adults with type 1 diabetes transitioning from pediatric to adult care are at risk for adverse outcomes. We developed a survey to evaluate transition experiences in two groups of young adults with type 1 diabetes, before (PEDS) and after (ADULT) transition to adult care. We fielded an electronic survey to young adults (18 to <30 years) at 60 T1D Exchange Clinic Registry centers. Surveys were completed by 602 young adults, 303 in the PEDS group (60% female, age 20 ± 2 years) and 299 in the ADULT group (62% female, age 24 ± 3 years). In the PEDS group, mean anticipated transition age was 22 ± 2 years; 64% remained in pediatric care because of emotional attachment to the provider. The ADULT group transitioned at age 19 ± 2 years, mainly after pediatric provider recommendation. More than 80% of respondents reported receiving counseling on type 1 diabetes self-management and screening tests from pediatric providers, but less than half (43% PEDS and 33% ADULT) reported discussing reproductive health. In the PEDS group, half had discussed transfer with pediatric providers. Of the ADULT participants, 63% received an adult provider referral, and 66% felt mostly/completely prepared to transition. ADULT participants with fewer pretransition pediatric visits or who felt unprepared for transition had increased odds of gaps >6 months between pediatric and adult care. Receipt of transition preparation counseling was not associated with self-reported hemoglobin A 1c <7.0% in either group. These results support the need for intensive efforts to integrate transition preparation counseling and care coordination into pediatric type 1 diabetes care. © 2017 by the American Diabetes Association.

Health-related quality of life (HRQOL) has been recognized as an important health outcome measurement for pediatric patients. One of the most promising instruments in measuring pediatric HRQOL emerged in recent years is the Pediatric Quality of Life Inventory (PedsQL™). The PedsQL™ 3.0 Asthma Module, one of the PedsQL™disease-specific scales, was designed to measure HRQOL dimensions specifically tailored for pediatric asthma. The present study is aimed to evaluate the psychometric properties of the Chinese version of the PedsQL™ 3.0 Asthma Module. The PedsQL™ 3.0 Asthma Module was translated into Chinese following the PedsQL™ Measurement Model Translation Methodology. The Chinese version scale was administered to 204 children with asthma and 337 parents of children with asthma from four Triple A hospitals. The psychometric properties were then evaluated. The percentage of missing value for each item of the scale ranged from 0.00% to 8.31%. All child self-report subscales and parent proxy-report subscales approached or exceeded the minimum reliability standard of 0.70 for alpha coefficient, except 3 subscales of Young Child (aged 5-7) self-report (alphas ranging from 0.59 to 0.68). Test-retest reliability was satisfactory with intraclass correlation coefficients (ICCs) which exceeded the recommended standard of 0.80 in all subscales. Correlation coefficients between items and their hypothesized subscales were higher than those with other subscales. The PedsQL™ 3.0 Asthma Module distinguished between outpatients and inpatients. Patients with mild asthma reported higher scores than those with moderate/severe asthma in majority of subscales. The intercorrelations among the PedsQL™ 3.0 Asthma Module subscales and the PedsQL™ 4.0 Generic Core Scales were in medium to large effect size. The child self-report scores were consistent with the parent proxy-report scores. The Chinese version of the PedsQL™ 3.0 Asthma Module has acceptable psychometric properties, except the internal consistency reliability for Young Child (aged 5-7) self-report. Further studies should be focused on testing responsiveness of the Chinese version scale in longitudinal studies, evaluating the reliability and validity of the scale for the patients with severe asthma or teens independently, and assessing HRQOL of children with asthma in other areas.

Infections remain a serious complication in pediatric oncology patients. To determine if daily bathing with Chlorhexidine gluconate can decrease the rate of nosocomial infection in pediatric oncology patients, we reviewed rates of infections in pediatric oncology patients over a 14-month span. Intervention group received daily bath with Chlorhexidine, while the control group did not receive daily bath. The results showed that daily bath with antiseptic chlorhexidine as daily prophylactic antiseptic topical wash leads to decreased infection density amongst the pediatric oncology patients, especially in patients older than 12 years of age. Furthermore, daily chlorhexidine bathing significantly reduced the rate of hospital acquired infection in patients older than 12 years of age. The findings of this study suggest that daily bathing with chlorhexidine may be an effective measure of reducing nosocomial infection in pediatric oncology patients.

The aim of this registry is to provide data on age-related clinical features of suspected myocarditis and to create a study platform allowing for deriving diagnostic criteria and, at a later stage, testing therapeutic interventions in patients with myocarditis. After an initial 6-month pilot phase, MYKKE was opened in June 2014 as a prospective multicenter registry for patients from pediatric heart centers, university hospitals, and community hospitals with pediatric cardiology wards in Germany. Inclusion criteria consisted of age<18 years and hospitalization for suspected myocarditis as leading diagnosis at the discretion of the treating physician. By December 31, 2015, fifteen centers across Germany were actively participating and had enrolled 149 patients. Baseline data reveal 2 age peaks (<2 years, >12 years), show higher proportions of males, and document a high prevalence of severe disease courses in pediatric patients with suspected myocarditis. Severe clinical courses and early adverse events were more prevalent in younger patients and were related to severely impaired leftventricular ejection fraction at initial presentation. MYKKE represents a multicenter registry and research platform for children and adolescents with suspected myocarditis that achieve steady recruitment and generate a wide range of real-world data on clinical course, diagnostic workup, and treatment of this group of patients. The baseline data reveal the presence of 2 age peaks and provide important insights into the severity of disease in children with suspected myocarditis. In the future, MYKKE might facilitate interventional substudies by providing an established collaborating network using common diagnostic approaches. Copyright © 2017 Elsevier Inc.

Outcome of children with nephrotic syndrome has continued to improve over time. However minimal data exist to describe health-related quality of life in children with nephrotic syndrome. This cross sectional study was conducted over a period of six months to assess the health related quality of life in children with nephrotic syndrome in the Department of Pediatric Nephrology, Dhaka Medical College Hospital, Bangladesh. Fifty children (age ranged 2-12 years) with nephrotic syndrome who had three or more relapses diagnosed at least one year back receiving treatment and on follow up were included in this study. Quality of Life scores were collected using Bengali translated instruments- the Pediatric Quality of Life Inventory™ (PedsQL™) version 4.0 Generic Scale and the Pediatric Quality of Life Questionnaire for Nephrotic Syndrome proxy-report from parents. Medical data and Demographic data were collected from medical records, and from parents in outpatient department or hospital ward. Interviews of eligible guardians were performed individually to collect quality of life (QoL) scores. Among 50 children, mean±SD age of the children was 7±2.92 years. Most children were male (58%). Female parents respondent during interview were 62%, most parents (48%) were very poor in socioeconomic condition. Most children had frequent relapses (60%). Median time since diagnosis was 2 years. Regarding PedsQL scores, child age with physical summary score (p value <0.001), child age with social summary score (p value 0.003), frequent relapse with kidney disease summary score (p value 0.04) and time since diagnosis (p value <0.001) were statistically significant. In conclusion physical and social summary score were worst. Frequent relapse found to be an important factor in impaired QoL. Prolonged duration of the disease activity was associated with significant impairment of QoL.

This study was planned in an attempt to develop a scale for the quality of life in pediatric oncology patients aged 7-12, with child and parents forms. In collecting the study data, we used the Child and Parent Information Form, Visual Quality of Life Scale, Scale for Quality of Life Pediatric Oncology Patients Aged 7-12 and the Scale for the Quality of Life in Pediatric Oncology Patients Aged 7-12 for Parents. We also used Pearson correlation analysis, the Cronbach alpha coefficient, factor analysis and ROC analysis for the study data. In this study, the total Cronbach alpha value of the parent form was 0.96, the total factor load being 0.54-0.90 and the total variance explained was 82.5%. The cutoff point of the parent form was 93 points. The total Cronbach alpha value for the child form was 0.96, with a total factor load of 0.55-0.91 and the total variance being explained was 78.3%. The cutoff point of the child form was 65 points. This study suggests that the Scale for Quality of Life in Pediatric Oncology Patients Aged 7-12 Child and Parents Forms are valid and reliable instruments in assessing the quality of life of children.

Heart rate (HR) and blood pressure (BP) form the basis for monitoring the physiological state of patients. Although norms have been published for healthy and hospitalized children, little is known about their distributions in critically ill children. The objective of this study was to report the distributions of these basic physiological variables in hospitalized critically ill children. Continuous data from bedside monitors were collected and stored at 5-s intervals from 3,677 subjects aged 0-18 years admitted over a period of 30 months to the pediatric and cardiac intensive care units at a large quaternary children's hospital. Approximately 1.13 billion values served to estimate age-specific distributions for these two basic physiological variables: HR and intra-arterial BP. Centile curves were derived from the sample distributions and compared to common reference ranges. Properties such as kurtosis and skewness of these distributions are described. In comparison to previously published reference ranges, we show that children in these settings exhibit markedly higher HRs than their healthy counterparts or children hospitalized on in-patient wards. We also compared commonly used published estimates of hypotension in children (e.g., the PALS guidelines) to the values we derived from critically ill children. This is a first study reporting the distributions of basic physiological variables in children in the pediatric intensive care settings, and the percentiles derived may serve as useful references for bedside clinicians and clinical trials.

The purpose of this study was to analyze the experience with peritoneal dialysis (PD) at a high-volume, single center institution that supports a rural population. From 2000 to 2010, 88 children (median age: 1.98 years, [range: 2 days-20.2 years]) received 134 PD catheters for the management of acute and chronic renal failure. The primary outcome of interest was the incidence of primary PD catheter failure (replacement or revision within 60 days). Operative technique, longitudinal outcomes, and time intervals to transplantation were analyzed. Median time to transplant from the institution of dialysis was 1.4 years [range: 0.3-6.4 years]. Primary catheter failure occurred in 24.6% of cases. Infants less than 6 months of age demonstrated an increased incidence of primary catheter failure (p = 0.02). The operative technique for catheter placement was not associated with the incidence of primary failure. Postoperative complications included peritonitis (22.7%), omental plugging (11.9%), pericatheter drainage (9.0%), and exit site infection (3.0%). Peritoneal dialysis provides a safe and effective renal replacement therapy for regional pediatric centers that serve a rural population. However, primary catheter failure rates remain high at 24.6%. The surgical technique for placement had no effect on this failure rate in our patient population. Infants less than 6 months of age are at increased risk for primary catheter failure and warrant intensive surveillance. Copyright © 2013. Published by Elsevier Inc.

Background and objectives Poor linear growth is a frequent complication of CKD. This study evaluated the effect of kidney transplantation on age-related growth of linear body segments in pediatric renal transplant recipients who were enrolled from May 1998 until August 2013 in the CKD Growth and Development observational cohort study. Design, setting, participants, & measurements Linear growth (height, sitting height, arm and leg lengths) was prospectively investigated during 1639 annual visits in a cohort of 389 pediatric renal transplant recipients ages 2–18 years with a median follow-up of 3.4 years (interquartile range, 1.9–5.9 years). Linear mixed-effects models were used to assess age-related changes and predictors of linear body segments. Results During early childhood, patients showed lower mean SD scores (SDS) for height (−1.7) and a markedly elevated sitting height index (ratio of sitting height to total body height) compared with healthy children (1.6 SDS), indicating disproportionate stunting (each P<0.001). After early childhood a sustained increase in standardized leg length and a constant decrease in standardized sitting height were noted (each P<0.001), resulting in significant catch-up growth and almost complete normalization of sitting height index by adult age (0.4 SDS; P<0.01 versus age 2–4 years). Time after transplantation, congenital renal disease, bone maturation, steroid exposure, degree of metabolic acidosis and anemia, intrauterine growth restriction, and parental height were significant predictors of linear body dimensions and body proportions (each P<0.05). Conclusions Children with ESRD present with disproportionate stunting. In pediatric renal transplant recipients, a sustained increase in standardized leg length and total body height is observed from preschool until adult age, resulting in restoration of body proportions in most patients. Reduction of steroid exposure and optimal metabolic control before and after transplantation are promising measures to further improve growth outcome. PMID:25352379

Most health-related quality of life assessments are designed for either children or adults and have not been evaluated for adolescent and young adult survivors of pediatric cancer. The objective of this study was to examine the feasibility, reliability, and validity of the Pediatric Quality of Life Inventory (PedsQL ™ Generic Core Scales, Cancer Module, and Multidimensional Fatigue Scale in adult survivors of pediatric cancer. Adult survivors (n = 64; Mean age 35 year old; >2 years after treatment) completed the PedsQL™ Generic Core Scales, Cancer Module, and Multidimensional Fatigue Scale. Feasibility was examined with floor and ceiling effects; and internal consistency was determined by Cronbach's coefficient alpha calculations. Inter-factor correlations were also assessed. Significant ceiling effects were observed for the scales of social function, nausea, procedural anxiety, treatment anxiety, and communication. Internal consistency for all subscales was within the recommended ranges (α ≥ 0.70). Moderate to strong correlations between most Cancer Module and Generic Core Scales (r = 0.25 to r = 0.76) and between the Multidimensional Fatigue Scale and Generic Core Scales (r = 0.37 to r = 0.73). The PedsQL™ Generic Core Scales, Cancer Module, and Multidimensional Fatigue Scale appear to be feasible for an older population of pediatric cancer survivors; however, some of the Cancer Module Scales (nausea, procedural/treatment anxiety, and communication) were deemed not relevant for long-term survivors. More information is needed to determine whether the issues addressed by these modules are meaningful to long-term adult survivors of pediatric cancers. Copyright © 2012 Wiley Periodicals, Inc.

Characterization of optically stimulated luminescence dosimeters and investigating their potential for estimating pediatric organ doses in multi-slice computed tomography

NASA Astrophysics Data System (ADS)

Al-Senan, Rani Mohammed

Recent epidemiologic studies have shown a strong association between the relatively high doses of pediatric CT and the risk of cancer. Quantifying organ doses, as a measure of the risk, is commonly based on either direct anthropomorphic phantom measurements or Monte Carlo simulation. The major disadvantage in the phantom approach is its high cost especially that, for pediatric CT dosimetry, various phantom sizes are required to represent different age groups of children. On the other hand, Monte Carlo simulation, although not considered costly, requires validation by anthropomorphic phantom measurements. The aim of this project was to develop two methods of organ dose estimation in pediatric CT: 1) from the measured surface dose using optically stimulated luminescence dosimeters (OSLDs) and 2) by measuring the circumference of the body part being scanned as well as knowing the scan parameters. The project was based on a study proposed by the surgery department to monitor radiation exposure to children during their CT examination in the ER. A total of 200 pediatric patients were enrolled in this study which used OSLDs to monitor the doses. Specific aim 1 of this project was to characterize the OSLDs in the diagnostic energy range. Specific aim 2(a) was to find relationships between the patients' doses from OSLDs and both scan CTDI and the measured circumference. In specific aim 2(b) we carried out measurements using CTDI phantoms to investigate the relationships studied in specific aim 2(a). Specific aim 3 was to come up with models to estimate select organ doses from measuring surface dose or by using the circumference of the body part. To do this, pediatric examinations were simulated using a set of pediatric anthropomorphic phantoms in which doses of select organs were measured.

In the Democratic Republic of Congo, the incidence of sickle cell anemia (SCA) is estimated to affect 30,000 to 40,000 neonates per year. However, there is paucity of data on acute clinical manifestations in sickle cell children. In these circumstances, it is difficult to develop a health care policy for an adequate management of sickle cell patients. This was a seven years' retrospective study of children admitted with acute sickle cell crisis in the Department of Pediatrics in University Hospital of Kinshasa, Kinshasa, the Democratic Republic of Congo. A total of 108 patients were identified as having SCA. There were 56 (51%) girls and 52 (49%) boys. Median age was 10.5 years (range 1-24 years). No child was diagnosed by neonatal screening. The median age of diagnosis of sickle cell anemia was 90 months (range: 8-250 months). The median age at the first transfusion was 36 months (range 4-168). In this series, 61 (56.5%) patients were eligible for hydroxyurea. However, this treatment was only performed in 4 (6.6%) of them. Pain episodes, acute anemic crisis and severe infection represent respectively 38.2%, 34.3% and 21.9% of events. Altered sensorium and focal deficit were encountered occasionally and represented 3.4% of acute events. Acute renal manifestations, cholelithiasis and priapism were rarely reported, in this cohort. In Kinshasa, the care of patients suffering from sickle cell anemia is characterized by the delayed diagnosis and low detection of organ complications compared to reports of Western countries. This situation is due to resources deficiencies.

Implementing an anterior cruciate ligament injury prevention program to athletes before the age at which the greatest injury risk occurs (15-17 years) is important from a prevention standpoint. However, it is unknown whether standard programs can modify lower extremity biomechanics in pediatric populations or if specialized training is required. To compare the effects of traditional and age-specific pediatric anterior cruciate ligament injury prevention programs on lower extremity biomechanics during a cutting task in youth athletes. The authors hypothesized that the age-specific pediatric program would result in greater sagittal plane motion (ie, hip and knee flexion) and less motion in the transverse and frontal plane (ie, knee valgus, knee and hip rotation) as compared with the traditional program. Randomized controlled trial; Level of evidence, 1. Sixty-five youth soccer athletes (38 boys, 27 girls) volunteered to participate. The mean age of participants was 10 ± 1 years. Teams (n, 7) were cluster randomized to a pediatric injury prevention program, a traditional injury prevention program, or a control group. The pediatric program was modified from the traditional program to include more feedback, progressions, and variety. Teams performed their programs as part of their normal warm-up routine. Three-dimensional lower extremity biomechanics were assessed during a sidestep cutting task before and after completion of the 9-week intervention period. The pediatric program reduced the amount of knee external rotation at initial ground contact during the cutting task, F ((2,62)) = 3.79, P = .03 (change: pediatric, 7.73° ± 10.71°; control, -0.35° ± 7.76°), as compared with the control group after the intervention period. No other changes were observed. The injury prevention program designed for a pediatric population modified only knee rotation during the cutting task, whereas the traditional program did not result in any changes in cutting biomechanics. These findings suggest limited effectiveness of both programs for athletes younger than 12 years of age in terms of biomechanics during a cutting task.

Achondroplasia (ACH) and hypochondroplasia (HCH) are the most common form of short-limb skeletal dysplasias caused by activated fibroblast growth factor receptor 3 (FGFR3) signaling. Although decreased bone mass was reported in gain-of-function mutation in Fgfr3 mice, both disorders have never been described as osteoporotic. In the present study, we evaluated bone mineral density (BMD) in ACH and HCH patients. We measured spinal BMD (L1-L4) in 18 ACH and four HCH patients with an average age of 19.8 ± 7.5 years (range, 10-33 years). BMD Z-score in each individual was calculated for normalizing age and gender. Correlation between body mass index (BMI) and BMD was analyzed. Moreover, BMD and Z-score were compared between ACH patients and HCH patients. The average BMD of ACH/HCH patients was 0.805 ± 0.141 g/cm(2) (range, 0.554-1.056 g/cm(2) ), resulting in an average Z-score of -1.1 ± 0.8 (range, -2.4 to 0.6) of the standard value. A slightly positive correlation was observed between BMI and BMD (r = 0.45; P = 0.13). There was no significant difference in BMD and Z-score between ACH and HCH patients. Spinal BMD was reduced in ACH/HCH patients, and was mildly correlated with individual BMI. We should carefully monitor BMD and examine osteoporosis-related symptoms in adolescent and adult ACH/HCH patients. © 2016 Japan Pediatric Society. © 2015 Japan Pediatric Society.

To characterize and compare pharmacokinetic parameters in children and adults treated with temozolomide (TMZ) administered for 5 days in three doses daily, and to evaluate the possible relationship between AUC values and hematologic toxicity. TMZ pharmacokinetic parameters were characterized in pediatric and adult patients with primary central nervous system tumors treated with doses ranging from 120 to 200 mg/m2 per day, divided into three doses daily for 5 days. Plasma levels were measured over 8 h following oral administration in a fasting state. A total of 40 courses were studied in 22 children (mean age 10 years, range 3-16 years) and in 8 adults (mean age 30 years, range 19-54 years). In all patients, a linear relationship was found between systemic exposure (AUC) and increasing doses of TMZ. Time to peak concentration, elimination half-life, apparent clearance and volume of distribution were not related to TMZ dose. No differences were seen among TMZ C(max), t(1/2), V(d) or CL/F in children compared with adults. Intra- and interpatient variability of systemic exposure were limited in both children and adults. No statistically significant differences were found between the AUCs of children who experienced grade 4 hematologic toxicity and children who did not. No difference appears to exist between pharmacokinetic parameters in adults and children when TMZ is administered in three doses daily. Hematologic toxicity was not related to TMZ AUC. AUC measurement does not appear to be of any use in optimizing TMZ treatment.

Supracondylar fractures of the humerus are among the most common elbow injuries in the pediatric population. Because of the significant morbidity associated with treating displaced pediatric supracondylar humerus fractures, most community-based orthopedic surgeons prefer to transfer these injuries to specialty children's hospitals. Our intention in writing this article was to document and evaluate the results we obtained using the lateral diverging pin technique to treat patients at our community hospital. In doing so, we set out to determine if our results were comparable to those of specialty hospitals, allowing us in the future to eliminate the inconvenience placed on patients and their families when being transferred to a specialty facility. We retrospectively reviewed the patients treated surgically at our institution for a closed Gartland type II or type III supracondylar distal humerus fracture during the months of September and October of 2005. The medical records and radiographs of all children who had been treated for a displaced extension-type supracondylar humerus fractures were evaluated. The data recorded from the chart review included the age and sex of the patients, preoperative and postoperative neurovascular status, operative techniques (2 vs 3 lateral entry point Kirschner wires), and the operative time (start to close). The radiographs were reviewed to determine the Gartland type of fracture and the Baumann angle on the anteroposterior film immediately postoperative and at the time of fracture union. Four Gartland type II and 3 Gartland type III fractures were identified during the study period. There were 3 boys and 4 girls with a mean age of 6.29 years (range, 3.92-8.58 years). The mean immediate postoperative Baumann angle was 18.29 degrees (range, 10-25 degrees). At the time of fracture union, the mean Baumann angle was 19.0 degrees (range, 14-22 degrees). The mean range-of-motion loss as compared with the extension loss (range, 10-2 degrees) and 4.57 degrees of flexion loss (range, 10-2 degrees). The mean operative time was 20.43 minutes (range, 7-37 minutes). Our results show the change in Baumann angle and loss of range of motion compare favorably with results of studies done at specialty hospitals. We believe that the divergent lateral pinning technique, in combination with postoperative splinting and a sling can provide excellent results while eliminating the risk of injury to the ulnar nerve. With this knowledge, we feel that the advantage to treating these fractures at a community hospital is the elimination of the anxiety, stress, and time spent waiting in the emergency department of multiple hospitals.

The aim of this article is to assess Tamil Nadu pediatric computed tomography (CT) diagnostic reference levels (DRLs) by collecting radiation dose data for the most commonly performed CT examinations. This work was performed for thirty CT scanners installed in various parts of the Tamil Nadu region. The patient cohort was divided into two age groups: <1 year, and 1–5 years. CT dose indices were measured using a 10 cm3 pencil ion chamber with pediatric head and body polymethyl methacrylate phantoms. Dose data such as volumetric CT dose index (CTDIv) and dose length product (DLP) on a minimum of twenty average-sized pediatric patients in each category were recorded to calculate a mean site CTDIv and DLP value. The rounded 75th percentile was used to calculate a pediatric DRL for each hospital, and then region by compiling all results. Data were collected for 3600 pediatric patients. Pediatric CT DRL for two age groups: <1 year (CTDIv and DLP of head [20 mGy, 352 mGy.cm], chest [7 mGy, 120 mGy.cm] and abdomen [12 mGy, 252 mGy.cm]), and 1–5 years (CTDIv and DLP of head [38 mGy, 505 mGy.cm], chest [8 mGy, 132 mGy.cm] and abdomen [14 mGy, 270 mGy.cm]) for select procedures have been calculated. Proposed pediatric DRLs of CTDIv and DLP for head procedure were lower, and for chest and abdomen procedures were higher than European pediatric DRLs for both age groups. PMID:28405108

The development of a population of 4D pediatric XCAT phantoms for imaging research and optimization

DOE Office of Scientific and Technical Information (OSTI.GOV)

Segars, W. P., E-mail: paul.segars@duke.edu; Norris, Hannah; Sturgeon, Gregory M.

Purpose: We previously developed a set of highly detailed 4D reference pediatric extended cardiac-torso (XCAT) phantoms at ages of newborn, 1, 5, 10, and 15 yr with organ and tissue masses matched to ICRP Publication 89 values. In this work, we extended this reference set to a series of 64 pediatric phantoms of varying age and height and body mass percentiles representative of the public at large. The models will provide a library of pediatric phantoms for optimizing pediatric imaging protocols. Methods: High resolution positron emission tomography-computed tomography data obtained from the Duke University database were reviewed by a practicingmore » experienced radiologist for anatomic regularity. The CT portion of the data was then segmented with manual and semiautomatic methods to form a target model defined using nonuniform rational B-spline surfaces. A multichannel large deformation diffeomorphic metric mapping algorithm was used to calculate the transform from the best age matching pediatric XCAT reference phantom to the patient target. The transform was used to complete the target, filling in the nonsegmented structures and defining models for the cardiac and respiratory motions. The complete phantoms, consisting of thousands of structures, were then manually inspected for anatomical accuracy. The mass for each major tissue was calculated and compared to linearly interpolated ICRP values for different ages. Results: Sixty four new pediatric phantoms were created in this manner. Each model contains the same level of detail as the original XCAT reference phantoms and also includes parameterized models for the cardiac and respiratory motions. For the phantoms that were 10 yr old and younger, we included both sets of reproductive organs. This gave them the capability to simulate both male and female anatomy. With this, the population can be expanded to 92. Wide anatomical variation was clearly seen amongst the phantom models, both in organ shape and size, even for models of the same age and sex. The phantoms can be combined with existing simulation packages to generate realistic pediatric imaging data from different modalities. Conclusions: This work provides a large cohort of highly detailed pediatric phantoms with 4D capabilities of varying age, height, and body mass. The population of phantoms will provide a vital tool with which to optimize 3D and 4D pediatric imaging devices and techniques in terms of image quality and radiation-absorbed dose.« less

To examine relationships among age, gender, anthropometrics, and dynamic balance. Height, weight, and arm and foot length were measured in 160 children with typical development aged 5 to 12 years. Dynamic balance was assessed using the Timed Up and Go (TUG) test, Pediatric Reach Test (PRT), and Pediatric Balance Scale (PBS). Moderate to good positive relationships (r = 0.61 and r = 0.56) were found between increasing age and PRT and PBS scores. A fair negative relationship (r = -0.49) was observed between age and TUG test. No significant gender-by-age group difference was observed. Age had the strongest influence on TUG and PBS scores; arm length had the strongest influence on PRT scores. Dynamic balance ability is directly related to chronological age. Age and arm length have the strongest relationships with balance scores. These findings may assist pediatric therapists in selecting dynamic balance tests according to age rather than specific diagnosis.

Pressure Ulcer Risk and Prevention Practices in Pediatric Patients: A Secondary Analysis of Data from the National Database of Nursing Quality Indicators®.

Little is known about pressure ulcer prevention practice among pediatric patients. To describe the frequency of pressure ulcer risk assessment in pediatric patients and pressure ulcer prevention intervention use overall and by hospital unit type, a descriptive secondary analysis was performed of data submitted to the National Database for Nursing Quality Indicators® (NDNQI®) for at least 3 of the 4 quarters in 2012. Relevant data on pressure ulcer risk from 271 hospitals across the United States extracted from the NDNQI database included patient skin and pressure ulcer risk assessment on admission, time since the last pressure ulcer risk assessment, method used to assess pressure ulcer risk, and risk status. Extracted data on pressure ulcer prevention included skin assessment, pressure-redistribution surface use, routine repositioning, nutritional support, and moisture management. These data were organized by unit type and merged with data on hospital characteristics for the analysis. The sample included 39 984 patients ages 1 day to 18 years on 678 pediatric acute care units (general pediatrics, pediatric critical care units, neonatal intensive care units, pediatric step-down units, and pediatric rehabilitation units). Descriptive statistics were used to analyze study data. Most of the pediatric patients (33 644; 89.2%) were assessed for pressure ulcer risk within 24 hours of admission. The Braden Q Scale was frequently used to assess risk on general pediatrics units (75.4%), pediatric step-down units (85.5%), pediatric critical care units (81.3%), and pediatric rehabilitation units (56.1%). In the neonatal intensive care units, another scale or method was used more often (55% to 60%) to assess pressure ulcer risk. Of the 11 203 pediatric patients (39%) determined to be at risk for pressure ulcers, the majority (10 741, 95.8%) received some kind of pressure ulcer prevention intervention during the 24 hours preceding the NDNQI pressure ulcer survey. The frequency of prevention intervention use among those at risk ranged from 99.2% for skin assessment to 70.7% for redistribution surface use. Most pediatric patients are being assessed for pressure ulcer risk, but the implementation of interventions to prevent pressure ulcers among children needs to be improved. Future qualitative research should be conducted to determine how and when clinical judgment is used to assess pressure ulcer risk and the type of pressure-redistribution surfaces used among younger pediatric patients.

Patients with chronic illnesses are known to have anxiety disorders and are likely to be depressed. Anxiety and depression (A/D) has been studied in adults with spina bifida (SB), however, no study has directly screened for A/D in pediatric patients with neurogenic bladder (NB) and their caregivers. The aims of our study were to determine the prevalence of A/D in caregivers of all children with SB and other NB dysfunction and in adolescents with validated screening measures. This was a preliminary cross-sectional screening investigation for A/D in pediatric patients with NB and their caregivers and adolescents with NB. Pediatric patients were defined as ages birth to 19 years and adolescents as ages 10 years-19 years. A caregiver was self-defined as a primary parent/guardian who took care of the pediatric patient for a majority of their time on a daily basis. We contacted 75 families by mail, of which 15 returned the consent and completed the questionnaires. Subsequently, 25 consecutive families whose children were seen for routine office appointments by the pediatric urology service at the Albany Medical Center in New York participated in person. 22 adolescents completed the Hospital Anxiety and Depression Scale (HADS). 47 caregivers completed both the HADS and the Center for Epidemiologic Studies Depression Scale (CES-D). Depression among adolescents: Of the 22 adolescents who completed the HADS, the median HADS score was 5.5 (Inter-quartile range (IQR): 1.75-8.75) for anxiety and 1.5 (IQR: 0-4.25) for depression; both scores were within the normal range (<8/21). Individual abnormal HADS scores (≥8/21) were seen in 6/22 (27%) for anxiety and 1/22 (5%) for depression. Anxiety and depression among caregivers: Of the 47 caregivers who completed the HADS and CES-D, the median HADS score was 7 (IQR: 4-11) for anxiety and 4 (IQR: 1-7) for depression; both scores were within the normal range. Individual abnormal HADS scores were seen in 23/47 (49%) for anxiety and 10/47 (21%) for depression. Abnormal CES-D scores (>15) were seen in 15/47 (32%). The median CES-D scores were 8 (IQR: 3-19). In this preliminary screening study, we found considerable anxiety in adolescents with NB and both A/D in caregivers. When screening by two validated surveys, adolescents with NB had median scores for A/D that were normal; yet 27% of these patients exhibited scores for anxiety that outwit the normal range. For the caregivers, the median scores were also normal; yet 49% and 32% had scores for A/D, respectively, that were abnormal. SB among pediatric patients has been shown to result in alterations in daily functioning and to increase the dependency on adult care, factors that are associated with altered self-concept, psychological distress, including A/D. Our findings underscore such results from previous studies. In caregivers, we observed a higher prevalence of anxiety than adolescents; similar findings have been reported for caregivers of other chronic conditions. Surprisingly, in caregivers, a lower percentage of scores for depression was observed. Although we have no data on the cause of this finding this may be related to a caregiver's ability to adapt to the demands of the situation in chronic illness or perhaps, lower expectations. The cross-sectional nature of our study limited us to draw any causal relationships for anxiety or depression between neurogenic patients and their caregivers. Despite our study limitations, the prevalence of anxiety in adolescents and in the caregivers is striking. Our data highlight that clinicians should screen for A/D more aggressively in pediatric patients with NB dysfunction and in their caregivers. Copyright © 2015 Journal of Pediatric Urology Company.

The objective of this study was to evaluate the entrance surface air kerma in pediatric chest radiography. An evaluation of 301 radiographical examinations in anterior-posterior (AP) and posterior-anterior (PA) (166 examinations) and lateral (LAT) (135 examinations) projections was performed. The analyses were performed on patients grouped by age; the groups included ages 0-1 y, 1-5 y, 5-10 y, and 10-15 y. The entrance surface air kerma was determined with DoseCal software (Radiological Protection Center of Saint George's Hospital, London) and thermoluminescent dosimeters. Two different exposure techniques were compared. The doses received by patients who had undergone LAT examinations were 40% higher, on average, those in AP/PA examinations because of the difference in tube voltage. A large high-dose “tail” was observed for children up to 5 y old. An increase in tube potential and corresponding decrease in current lead to a significant dose reduction. The difference between the average dose values for different age ranges was not practically observed, implying that the exposure techniques are still not optimal. Exposure doses received using the higher tube voltage and lower current-time product correspond to the international diagnostic reference levels.

This article reports on the content range and measurement precision of an upper extremity (UE) computer adaptive testing (CAT) platform of physical function in children with cerebral palsy. Upper extremity items representing skills of all abilities were administered to 305 parents. These responses were compared with two traditional standardized measures: Pediatric Outcomes Data Collection Instrument and Functional Independence Measure for Children. The UE CAT correlated strongly with the upper extremity component of these measures and had greater precision when describing individual functional ability. The UE item bank has wider range with items populating the lower end of the ability spectrum. This new UE item bank and CAT have the capability to quickly assess children of all ages and abilities with good precision and, most importantly, with items that are meaningful and appropriate for their age and level of physical function.

Hospitals vary widely in the services they offer to care for pediatric burn patients. When a hospital does not have the ability or capacity to handle a pediatric burn, the decision often is made to transfer the patient to another short-term hospital. Transfers may be based on available specialty coverage for children; which adult and non-teaching hospitals may not have available. The effect these transfers have on costs and length of stay (LOS) has on pediatric burn patients is not well established and is warranted given the prominent view that pediatric hospitals are inefficient or more costly. The authors examined inpatient admissions for pediatric burn patients in 2003, 2006, and 2009 using the Kids' Inpatient Database, which is part of the Healthcare Cost and Utilization Project. ICD-9-CM codes 940 to 947 were used to define burn injury. The authors tested if transfer status was associated with LOS and total charges for pediatric burn patients, while adjusting for traditional risk factors (eg, age, TBSA, insurance status, type of hospital [pediatric vs adult; teaching vs nonteaching]) by using generalized linear mixed-effects modeling. A total of n = 28,777 children had a burn injury. Transfer status (P < .001) and TBSA (P < .001) was independently associated with LOS, while age, insurance status, and type of hospital were not associated with LOS. Similarly, transfer status (P < .001) and TBSA (P < .001) was independently associated with total charges, while age, insurance status, and type of hospital were not associated with total charges. In addition, the data suggest that the more severe pediatric burn patients are being transferred from adult and non-teaching hospitals to pediatric and teaching hospitals, which may explain the increased costs and LOS seen at pediatric hospitals. Larger more severe burns are being transferred to pediatric hospitals with the ability or capacity to handle these conditions in the pediatric population, which has a dramatic impact on costs and LOS. As a result, unadjusted, pediatric hospitals are seen as being inefficient in treating pediatric burns. However, since pediatric hospitals see more severe cases, after adjustment, type of hospital did not influence costs and LOS. TBSA and transfer status were the predictors studied that independently affect costs and LOS.

The clinical, endoscopic, and histologic findings of eosinophilic esophagitis (EoE) are well characterized; however, there have been very limited data regarding the radiologic findings of pediatric EoE. We report on the radiologic findings of pediatric EoE observed on barium esophagram and correlate them with the endoscopic findings. We identified children diagnosed with EoE in our center from 2004 to 2015. Two pediatric radiologists met after their independent evaluations of each fluoroscopic study to reach a consensus on each case. Clinical and endoscopic data were collected by retrospective chart review. Twenty-six pediatric EoE cases (age range 2-13 years; median 7.5 years) had barium esophagram done as part of the diagnostic approach for dysphagia. Thirteen children had abnormal radiologic findings of esophagus (50%): rings formation (n = 4), diffuse irregularity of mucosa (n = 8), fixed stricture formation (n = 3), and narrow-caliber esophagus (n = 10). Barium esophagram failed to show one of 10 cases of narrow-caliber esophagus and 10 of 14 cases of rings formation visualized endoscopically. The mean duration of symptoms prior to diagnosis of EoE was longer (3.7 vs. 1.7 year; p value 0.019), and the presentation with intermittent food impaction was commoner in the group with abnormal barium esophagram as compared to the group with normal barium esophagram (69% vs. 8%; p value 0.04). Barium swallow study is frequently normal in pediatric EoE. With the exception of narrow-caliber esophagus, our data show poor correlation between radiologic and endoscopic findings.

To review the literature on pediatric food choking risks, with the long-term goal of supporting legislation regulating the production, labeling, and distribution of high-risk foods. A PubMed search (Keywords: choking, obstruction, asphyxiation, foreign body, food) was conducted in July-September 2010 with publication dates ranging from 1966 to 2010. Articles related to pediatric foreign body aspiration (FBA) were selected by three independent reviewers. 1145 articles were initially identified. Abstracts were then screened utilizing a tool designed to isolate relevant pediatric choking events; this tool helped to only select abstracts which presented data on patients younger than 18 years of age who had choked on food items. Through this, a total of 72 pertinent articles were isolated (55 observational studies, 17 case reports/series). For each study, patient age, sex, foreign body location, presenting signs and symptoms, utility of radiographic studies, and type of foreign body detected in the majority of study participants were determined. A "majority" of patients for each study was predetermined arbitrarily to be 2/3 of the studied population. The majority of patients in each observational study was determined to be: male (87% of all studies) and age <5 years (95% of all studies). Aspirated foreign bodies were mostly detected in the right main bronchus foreign body (72% of all studies), and there were abnormal radiographic signs (81% of all studies) at the time of evaluation. Food-object foreign bodies were the most frequent factors associated with choking (94% of all studies). Childhood aspiration of food-objects is a significant public health issue. Although there is substantial legislation regulating non-food items that pose a choking hazard, equivalent guidelines do not exist for high-risk foods. Our study identifies and confirms several risk factors for pediatric FBA events. In doing so, it echoes the concerns and suggestions of various groups in supporting the development of legislation which may reduce the incidence of food-object aspiration. Copyright © 2013.

The objective of this review is to identify and synthesize the best international qualitative evidence on healthcare users' experiences of communication with healthcare professionals about children who have life-limiting conditions. For the purposes of this review, "healthcare users" will be taken to include children who have life-limiting conditions and their families. The question to be addressed is:What are healthcare users' experiences of communicating with healthcare professionals about children who have life-limiting conditions? The prospect of the death of a child from an incurable medical condition is harrowing, yet finding a way to discuss this prospect is crucial to maximize the quality of life for such children and their families. High-quality communication is well recognized as a core skill health care professionals need to maximize the quality of care they provide. This skill is valued by service users, who consistently rate it as one of the highest priorities for the care they receive. Evidence suggests, however, that healthcare professionals can feel ill-equipped or uncomfortable communicating with and about such children. Therefore, it is important to understand what represents high-quality communication and what is involved in accomplishing this within pediatric palliative care.In recent decades there has been an increased focus on providing palliative care for children who have life-limiting conditions. These are conditions for which no cure is available and for which the probable outcome is premature death. Palliative care may also be appropriate for children who have life-threatening conditions; these are conditions where there is not only a high probability of premature death but also a chance of long-term survival into adulthood Although pediatric palliative care is underpinned by the same philosophy as adult palliative care, children who have life-limiting conditions and their families have particular needs that distinguish them from users of adult palliative care. For example, at a physical level children are more likely than adults to have non-malignant conditions that follow trajectories in which children oscillate between feeling relatively well and acutely unwell. The social dynamic of their care is also radically different, particularly given the role of parents or guardians in making surrogate decisions about their child's care. Such factors warrant considering pediatric palliative care as distinct from palliative care more generally.Although the particular circumstances of children who have life-limiting conditions have led to development of pediatric palliative care, the particular provisions of this care differs among countries. One aspect of variation is the age range of patients. Pediatric palliative care is usually provided to neonates, infants, children, adolescents and young adults, but international variations in the definitions of these age ranges, particularly for adolescents and young adults, means pediatric palliative care is provided to different age groups in different countries. This review therefore adopts a pragmatic rather than an age-based definition of a pediatric palliative care, considering all studies relating to service users who are being cared for by pediatric rather than adult healthcare services.In catering for the unique needs of children who have life-limiting conditions and their families, pediatric palliative care aims to achieve pain and symptom management, enhanced dignity and quality of life, and psychosocial and spiritual care. It also seeks to incorporate care for patients' broader families and facilitating access to appropriate services and support. High-quality communication is crucial for achieving these aims. It enables healthcare users and providers to make decisions that underpin the care that is provided and the quality of the life that is possible for patients and their families.Although both users and providers recognize the value of high-quality communication with and about children who have life-limiting conditions, this does not mean that these stakeholders necessarily share the same perspective of what constitutes high-quality communication and the best way of accomplishing this. Focusing on healthcare users' experiences of communication with healthcare professionals about children who have life-limiting conditions, the present review will explore the subjective impact of professionals' communication on the people for whom they provide care.It may be necessary to consider a range of contextual factors to understand healthcare users' experiences of communicating with healthcare professionals about children who have life-limiting conditions. For instance, age, developmental stage, cognitive capacity, emotional and social strengths, and family dynamics can influence a child's level of involvement in discussions about their condition and care. Although there are factors that appear more consistent across the range of pediatric palliative care users, such as parents' preferences for being treated by healthcare professionals as partners in making decisions about the care of their child, there is not always such consistency. Nor is it clear whether such findings can be generalized across different cultural contexts. In appraising existing research, this systematic review will therefore consider the relationship between the context of individual studies and their reported findings.The primary aim of this review is to identify, appraise and synthesize existing qualitative evidence of healthcare users' experiences of communicating with healthcare professionals about children who have life-limiting conditions. The review will consider relevant details of these findings, particularly whether factors like age are relevant for understanding particular experiences of communication. An outcome of this review will be the identification of best available qualitative evidence that can be used to inform professional practice, as well as an identification of priorities for future research in pediatric palliative care.A preliminary search in MEDLINE and CINAHL found primary studies exploring healthcare users' experiences of aspects of communicating with healthcare professionals about children who have life-limiting conditions. A search was also conducted for existing systematic reviews in PubMed, CINAHL, EMBASE, PsycINFO, the Cochrane Database of Systematic Reviews, the JBI Database of Systematic Reviews and Implementation Reports, and PROSPERO. No systematic reviews on this topic were found.

To examine anthropometric and maturational characteristics at diagnosis in pediatric idiopathic intracranial hypertension (IIH). Retrospective, international, multisite study. Pediatric patients (2-18 years of age at diagnosis) with IIH. Body mass index (BMI), height, and weight Z-scores; sexual maturation. Cases of IIH were identified retrospectively based on diagnostic code, pediatric neuro-ophthalmologist databases, or both and updated diagnostic criteria (2013) were applied to confirm definite IIH. Anthropometric measurements were converted into age- and gender-specific height, weight, and BMI Z-scores CDC 2000 growth charts. When available, sexual maturation was noted. Two hundred thirty-three cases of definite IIH were identified across 8 sites. In boys, a moderate association between age and BMI Z-scores was noted (Pearson's correlation coefficient, 0.50; 95% confidence interval [CI], 0.30-0.66; P < 0.001; n = 72), and in girls, a weak association was noted (Pearson's correlation coefficient, 0.34; 95% CI, 0.20-0.47; P < 0.001; n = 161). The average patient was more likely to be overweight at diagnosis at age 6.7 years in girls and 8.7 years in boys, and obese at diagnosis at age 12.5 years in girls and 12.4 years in boys. Compared with age- and gender-matched reference values, early adolescent patients were taller for age (P = 0.002 in girls and P = 0.02 in boys). Data on Tanner staging, menarchal status, or both were available in 25% of cases (n = 57/233). Prepubertal participants (n = 12) had lower average BMI Z-scores (0.95±1.98) compared with pubertal participants (n = 45; 1.92±0.60), but this result did not reach statistical significance (P = 0.09). With updated diagnostic criteria and pediatric-specific assessments, the present study identifies 3 subgroups of pediatric IIH: a young group that is not overweight, an early adolescent group that is either overweight or obese, and a late adolescent group that is mostly obese. Data also suggest that the early adolescent group with IIH may be taller than age- and gender-matched reference values. Understanding these features of pediatric IIH may help to illuminate the complex pathogenesis of this condition. Copyright © 2016 American Academy of Ophthalmology. Published by Elsevier Inc.

Background Data from epidemiological studies investigating the prevalence and severity of malocclusions in children are of great relevance to public health programs aimed at orthodontic prevention. Previous epidemiological studies focused mainly on the adolescence age group and reported a prevalence of malocclusion with a high variability, going from 32% to 93%. Aim of our study was to assess the need for orthodontic treatment in a paediatric sample from Southern Italy in order to improve awareness among paediatricians about oral health preventive strategies in pediatric dentistry. Material and Methods The study used the IOTN-DHC index to evaluate the need for orthodontic treatment for several malocclusions (overjet, reverse overjet, overbite, openbite, crossbite) in a sample of 579 children in the 2-9 years age range. Results The most frequently altered occlusal parameter was the overbite (prevalence: 24.5%), while the occlusal anomaly that most frequently presented a need for orthodontic treatment was the crossbite (8.8%). The overall prevalence of need for orthodontic treatment was of 19.3%, while 49% of the sample showed one or more altered occlusal parameters. No statistically significant difference was found between males and females. Conclusions Results from this study support the idea that the establishment of a malocclusion is a gradual process starting at an early age. Effective orthodontic prevention programs should therefore include preschool children being aware paediatricians of the importance of early first dental visit. Key words:Orthodontic treatment, malocclusion, oral health, pediatric dentistry. PMID:28936290

Analysis of contextual variables in the evaluation of child abuse in the pediatric emergency setting.

Almeida, Ana Nunes de; Ramos, Vasco; Almeida, Helena Nunes de; Escobar, Carlos Gil; Garcia, Catarina

This article comprises a sample of abuse modalities observed in a pediatric emergency room of a public hospital in the Lisbon metropolitan area and a multifactorial characterization of physical and sexual violence. The objectives are: (1) to discuss the importance of social and family variables in the configuration of both types of violence; (2) to show how physical and sexual violence have subtypes and internal diversity. A statistical analysis was carried out in a database (1063 records of child abuse between 2004 and 2013). A form was applied to cases with suspected abuse, containing data on the child, family, abuse episode, abuser, medical history, and clinical observation. A factorial analysis of multiple correspondence was performed to identify patterns of association between social variables and physical and sexual violence, as well as their internal diversity. The prevalence of abuse in this pediatric emergency room was 0.6%. Physical violence predominated (69.4%), followed by sexual violence (39.3%). Exploratory profiles of these types of violence were constructed. Regarding physical violence, the gender of the abuser was the first differentiating dimension; the victim's gender and age range were the second one. In the case of sexual violence, the age of the abuser and co-residence with him/her comprised the first dimension; the victim's age and gender comprised the second dimension. Patterns of association between victims, family contexts, and abusers were identified. It is necessary to alert clinicians about the importance of social variables in the multiple facets of child abuse. Copyright © 2017 Sociedade Brasileira de Pediatria.

The treatment of stone disease is mostly similar in those adult and children. The standard treatment procedures are as follows: extracorporeal shock wave lithotripsy (ESWL), ureterorenoscopy (URS), percutaneous nephrolithotomy (PCNL), and laparoscopic surgery in selected cases. Open surgery (OS) is another option particularly in such cases with anatomic abnormalities of urinary tract. The present study aims to provide comparative results of stone removal procedures in preschool aged patients who were diagnosed with urinary system stone disease. The retrospective data of 616 pediatric preschool patients consulted with urinary system stone disease between January 2009 and July 2013 were evaluated. All patients were evaluated with Kidney-Ureter-Bladder (KUB) Xray and abdomino-pelvic ultrasound. Intravenous pyelography, unenhanced computed tomography (CT), and renal scintigraphy were performed when needed. Patients were categorized according to the procedures as: Group ESWL, Group URS, Group PNL, Group micro-PNL and Group OS. Following the procedures, opaque residual stones were evaluated with KUB Xray, and non-opaque residual stones were evaluated with unenhanced CT. In groups (ESWL, URS, PNL, micro-PNL, OS), the stone-free rate was 68%, 66%, 85%, 100% and 94 %, respectively. The stone analysis were observed as, calcium oxalate in 377 patients (61.2%), uric acid in 106 patients (17.2%), infection stone in 73 patients (11.8 %), and cysteine in 60 patients (9.7%). There was no significant difference in stone analysis between the groups (p > 0.05) (Table). Minimally invasive procedures are frequently preferred in the pediatric age urinary system stone disease. These procedures are ESWL, PCNL, and ureteroscopy [10,11]. Open surgery is reserved only for rare cases [12]. Similarly the current literature, 18 (2.9%) patients had anatomical anomaly and had high complex stone burden were treated with open surgery in our study. ESWL is a preferred treatment method for pediatric urolithiasis patients with a stone size <20 mm, and the rate of stone-free after ESWL ranges between 57 and 92% [13]. In a study showed the effect of stone size on the success rate in ESWL, the success rate was 91% for stones <10 mm, and 75% for stones >10 mm [15]. In the present study, stone-free rate was noted as 68% on 15 mm or lower stone size. PNL is commonly used to treat stone disease in preschool children [18-20]. In the beginning, urologists hesitated to use instruments suited for adults in case of pediatric kidneys. While some authors accept a cut-off value of 24 F for tract dilatation in the pediatric age, Desai et al. recommended a threshold value <22 F [19,21]. In our study, we used adult PNL instruments in the early period, whereas mini-PERC was performed in the later years. The success rate in PNL group was found as 85%. In recent years, the micro-PNL procedure has been developed to reduce/prevent the complications of standard PNL. In our study, the success rate was calculated as 100% with micro-PNL. This study has certain limitations. The major limitation of our study is its retrospective nature. In addition, sample size of micro-PNL group is fewer than other groups. The goal of kidney stone treatment is to achieve minimal kidney damage and a high success rate. Thus, the procedures are important in the pediatric age group where life expectancy is high, and particularly in the preschool age group. Copyright © 2015 Journal of Pediatric Urology Company.

Little information is available about survival of high-risk pediatric neuroblastoma patients in developing countries. We aimed to assess survival among high-risk pediatric neuroblastoma patients in La Plata, Argentina. Individuals eligible for our cohort were aged <20 yr when diagnosed with high-risk neuroblastoma and received cancer-directed therapy including stem cell transplantation at Hospital de Niños Sor Maria Ludovica between February 1999 and February 2015. We estimated overall survival probabilities using an extended Kaplan-Meier approach. Our study population comprised 39 high-risk neuroblastoma patients, of whom 39% were aged >4 yr at diagnosis, 54% were male, and 62% had adrenal neuroblastoma. We observed 18 deaths, and the median survival time of our study population was 1.7 yr. The five-yr overall survival probability was 24% (95% CL: 10%, 41%). In contrast, five-yr survival of high-risk neuroblastoma patients ranges between 23% and 76% in developed countries. Survival among high-risk neuroblastoma patients is generally poor regardless of geographic location, but our results illustrate dramatically worse survival for patients in a developing country. We speculate that the observed survival differences could be attenuated or eliminated with improvements in treatment and supportive care, but addressing these issues will require creative solutions because of resource limitations. © 2016 John Wiley & Sons A/S.

OBJECTIVES: The objective of this study was to evaluate the safety and efficacy of polyethylene glycol-electrolyte solution vs polyethylene glycol-3350 for the treatment of fecal impaction in pediatric patients. METHODS: A retrospective, observational, institutional review board–approved study was conducted over a 1-year time period. Patients were included in the study if they were admitted to the hospital with a diagnosis of fecal impaction or constipation and were treated with either polyethylene glycol-electrolyte solution (PEG-ES) or polyethylene glycol-3350 (PEG-3350). Patients were excluded if they were discharged prior to resolution of treatment and/or did not receive PEG-ES or PEG-3350. RESULTS: Fifty-one patients (ranging in age from 1 month to 15 years) were evaluated: 23 patients received PEG-ES and 28 patients received PEG-3350. Sex, race, age, and weight were not statistically different between the 2 groups. Resolution of fecal impaction was not significantly different between PEG-ES vs PEG-3350 (87% and 86%, respectively; p = 0.87). There was only 1 reported side effect with PEG-3350, vs 11 reported side effects with PEG-ES (p < 0.01). CONCLUSIONS: Theses results suggest that PEG-3350 is as effective as PEG-ES for the treatment of fecal impaction in pediatric patients and is associated with fewer side effects. PMID:26170773

Context: Factors influencing the outcome of surgical treatment of pediatric Cushing's disease (CD) have not been fully established. Objective: The aim of this study was to examine features influencing the outcome of surgery for pediatric CD. Design: In this prospective observational study, the clinical, imaging, endocrinological, and operative outcomes were analyzed in consecutive patients treated at the National Institutes of Health (NIH) from 1982 through 2010. Setting: The study was conducted in a tertiary referral center. Results: Two hundred CD patients (106 females, 94 males) were included. Mean age at symptom development was 10.6 ± 3.6 years (range, 4.0 to 19.0 y). Mean age at NIH operation was 13.7 ± 3.7 years. Twenty-seven patients (13%) had prior surgery at another institution. Magnetic resonance imaging identified adenomas in 97 patients (50%). When positive, magnetic resonance imaging accurately defined a discrete adenoma in 96 of the 97 patients (99%), which was more accurate than the use of ACTH ratios during inferior petrosal sinus sampling to determine adenoma lateralization (accurate in 72% of patients without prior surgery). A total of 195 of the 200 patients (98%) achieved remission after surgery (189 [97%] were hypocortisolemic; 6 [3%] were eucortisolemic postoperatively). Factors associated with initial remission (P < .05) included identification of an adenoma at surgery, immunohistochemical ACTH-producing adenoma, and noninvasive ACTH adenoma. Younger age, smaller adenoma, and absence of cavernous sinus wall or other dural invasion were associated with long-term remission (P < .05). A minimum morning serum cortisol of less than 1 μg/dl after surgery had a positive predictive value for lasting remission of 96%. Conclusions: With rare disorders, such as pediatric CD, enhanced outcomes are obtained by evaluation and treatment at centers with substantial experience. Resection of pituitary adenomas in pediatric CD in that setting can be safe, effective, and durable. Early postoperative endocrine testing predicts lasting remission. Because lasting remission is associated with younger age at surgery, smaller adenomas, and lack of dural invasion, early diagnosis should improve surgical outcome. PMID:23372173

To determine the age and sex characteristics of the children and type of dental procedures performed under dental general anesthesia (DGA) and to assess the results after six months to one year's follow-up. A sample of 30 patients treated under dental general anesthesia (DGA) during 2006-2007 in the Department of Pediatric Dentistry of China Medical University was reviewed. All the teeth were treated one time. The dental procedures performed included caries restoration, indirect pulp capping, pulpotomy, root canal therapy (RCT) and dental extraction. Oral prophylaxis and topical fluoride applications were performed on all teeth. Pit and fissure sealing was performed on all healthy premolars and molars. SPSS10.0 software package was used for statistical analysis. Chi-square test was used to analyze the difference of the sex distribution in different age group and the difference of dental procedures performed between the primary teeth and the permanent teeth. The age of the patients ranged from 19 months to 14 years. The mental retardation patients accounted for 10% and mental healthy patients accounted for 90% of the sample studied. Males were more than females with the ratio about 2 to 1 in each age group. The dental procedures performed were caries restoration (18.67%), indirect pulp capping (23.26%), pulpotomy (0.77%), RCT (29.16%), dental extractions (2.05%) and fissure sealants (26.09%). The percentage of RCT was higher than that of caries restoration in the primary teeth, whereas the result was opposite as for the permanent teeth as indicated by Chi-square test (X(2)=11.630, P=0.001). New dental caries was not found except 2 patients who suffered from dysnoesia and were not cooperative to have regular examination. Fillings were lost in 3 cases, with 3 anterior teeth and 2 posterior teeth after RCT. All the children could cooperate except two mental retardation patients during the follow-up visit. Caries restoration and RCT are the most frequently performed procedures in pediatric patients using DGA. This indicates the need to design and implement integrate control and prevention programs for special pediatric patients. DGA is a safe and effective behavior management technique to treat uncooperative children.

Two versions of the International Knee Documentation Committee (IKDC) Subjective Knee Evaluation form currently exist: the original version (1999) and a recently modified pediatric-specific version (2011). Comparison of the pediatric IKDC with the adult version in the adult population may reveal that either version could be used longitudinally. We hypothesize that the scores for the adult IKDC and pediatric IKDC will not be clinically different among adult patients aged 18 to 50 years. Randomized crossover study design. Level 2. The study consisted of 100 participants, aged 18 to 50 years, who presented to orthopaedic outpatient clinics with knee problems. All participants completed both adult and pediatric versions of the IKDC in random order with a 10-minute break in between. We used a paired t test to test for a difference between the scores and a Welch's 2-sample t test to test for equivalence. A least-squares regression model was used to model adult scores as a function of pediatric scores, and vice versa. A paired t test revealed a statistically significant 1.6-point difference between the mean adult and pediatric scores. However, the 95% confidence interval (0.54-2.66) for this difference did not exceed our a priori threshold of 5 points, indicating that this difference was not clinically important. Equivalence testing with an equivalence region of 5 points further supported this finding. The adult and pediatric scores had a linear relationship and were highly correlated with an R 2 of 92.6%. There is no clinically relevant difference between the scores of the adult and pediatric IKDC forms in adults, aged 18 to 50 years, with knee conditions. Either form, adult or pediatric, of the IKDC can be used in this population for longitudinal studies. If the pediatric version is administered in adolescence, it can be used for follow-up into adulthood.

Methods: The study consisted of 100 participants, aged 18 to 50 years, who presented to orthopaedic outpatient clinics with knee problems. All participants completed both adult and pediatric versions of the IKDC in random order with a 10-minute break in between. We used a paired t test to test for a difference between the scores and a Welch’s 2-sample t test to test for equivalence. A least-squares regression model was used to model adult scores as a function of pediatric scores, and vice versa. Results: A paired t test revealed a statistically significant 1.6-point difference between the mean adult and pediatric scores. However, the 95% confidence interval (0.54-2.66) for this difference did not exceed our a priori threshold of 5 points, indicating that this difference was not clinically important. Equivalence testing with an equivalence region of 5 points further supported this finding. The adult and pediatric scores had a linear relationship and were highly correlated with an R2 of 92.6%. Conclusion: There is no clinically relevant difference between the scores of the adult and pediatric IKDC forms in adults, aged 18 to 50 years, with knee conditions. Clinical Relevance: Either form, adult or pediatric, of the IKDC can be used in this population for longitudinal studies. If the pediatric version is administered in adolescence, it can be used for follow-up into adulthood. PMID:28080306

Pediatric central nervous system (CNS) atypical teratoid rhabdoid tumors (ATRT) are highly malignant tumors characterized by SMARCB1 gene abnormalities. Despite chemoradiation responsiveness, most children die of disease. No imaging findings distinguish ATRT from other malignant brain tumors. This study sought to describe magnetic resonance spectroscopy (MRS) of childhood CNS ATRT and identify metabolite patterns for diagnosis and disease status monitoring. Data from 7 children diagnosed with CNS ATRT from 2007 to 2010, whose imaging included MRS, were retrospectively reviewed. Age at diagnosis ranged from 2.5 to 54 months. Tumors were large with calcium and cysts and avid gadolinium enhancement. All were isointense on T1-weighted imaging and mildly hyperintense on T2-weighted imaging. Short-TE MRS showed prominent lactate+lipid and choline, minimal N-acetyl acetate (NAA), and rarely minimal myoinositol and low creatine peaks. Long TE showed prominent choline, minimal NAA, and rarely low lactate peaks. The combination of prominent choline and lactate+lipids peaks, and generally absent NAA and myoinositol peaks by MRS in this panel of ATRT expands existing information and provides a potentially distinct metabolite profile from other malignant pediatric brain tumors, including medulloblastoma. Prospective, comparative quantitative MRS of ATRT with other pediatric CNS tumors is warranted.

Emergence of extensively drug-resistant (XDR) bacteria has forced clinicians to use off-label antimicrobial agents such as tigecycline. We present our experience on salvage use of tigecycline for the treatment of infections caused by XDR Gram-negative bacteria in critically ill children and review published cases. We conducted a retrospective chart review in pediatric departments of a tertiary level hospital from January 2009 to May 2014. Patients were identified using pharmacy database. For the literature review, relevant articles were identified from PubMed. In our case series, 13 children (7 males) with a median age of 8 years (range, 2.5 months-14 years) received tigecycline for ≥2 days as treatment for healthcare-associated infections including 5 bacteremias, 6 lower respiratory tract infections, and 3 other infections. Isolated pathogens were XDR Gram-negative bacteria except 1. A loading dose (range, 1.8-6.5 mg/kg) was given in all except 2 cases. Maintenance dose was given at 1-3.2 mg/kg q12 h. Other antimicrobials including colistin and aminoglycosides (85% and 62%, respectively) were coadministered to all patients. No serious adverse events were detected in these very ill children. Twenty cases of children treated with tigecycline were previously published, mostly for multidrug-resistant/XDR bacteria. An episode of acute pancreatitis and neutrophil engraftment delay in 2 cases were reported during tigecycline treatment. Analyzing reported and all our cases together, mortality in bloodstream infections was 86%, whereas in nonbacteremic cases it was 24% (P = .009). Tigecycline, given at the range of administered doses as salvage therapy and in combination with other antimicrobial agents, seemed to be well tolerated in a series of mainly critically ill pediatric patients and demonstrated relatively good clinical response in nonbacteremic patients. © The Author 2016.

Accurate body temperature measurement is essential in providing timely care to critically ill patients. Current practice within the Pediatric ICU (PICU) at a Midwestern academic medical center is to obtain axillary temperatures in endotracheally intubated patients. According to research, axillary temperatures have greater variance than other forms of temperature measurement. Research in adult patients show that oral temperature measurement in endotracheally intubated patients is acceptable as the heated gases from the ventilator has no significant effect on measured temperatures. This study sought to determine if the same is true in pediatrics. Oral and axillary temperatures of endotracheally intubated pediatric patients were obtained during unit prescribed vital assessment intervals. Patients were divided into neonate, infant, and children age groups with 25 sets of temperatures obtained for each group. Descriptive statistics and Bland-Altman plot interpretation were performed to determine confidence intervals for each age group. Bland-Altman plot analysis of oral and axillary routes of temperature measurement showed a high positive correlation within all age groups studied. The infant age group showed lower correlation in comparison to neonates and children. The infant age group also had an outlier of data sets with lower oral temperatures as compared to the axilla. Oral temperature measurement is a viable alternative to axillary temperature measurement in endotracheally intubated pediatric patients. Correction factors for age groups were calculated for prediction of axillary temperature based on measured oral temperature. This study serves as evidence for practice change within the studied unit.

Retrospective review of prospectively accrued cohorts. We hypothesized that posterior-only vertebral column resection (PVCR) would result in improved postoperative pulmonary function, avoiding pulmonary insults from combined anterior/posterior approaches. Pulmonary function after PVCR for severe spinal deformity has not been previously studied. Previous studies have demonstrated impaired pulmonary performance after combined anterior/posterior fusions. Serial pulmonary function testing (PFTs) in 49 patients (27 pediatric, 22 adult) who underwent PVCR at a single institution was reviewed. Mean age at surgery was 28.7 years (range, 8-74 yr), and mean follow-up was 32 months (range, 23-64 mo). Thoracic PVCRs (T5-T11) were performed in 31 patients and thoracolumbar PVCRs (T12-L5) in 18 patients. Pediatric patients who underwent PVCR experienced both increased mean forced vital capacity (FVC) (2.10-2.43 L, P = 0.0005) and forced expiratory volume in 1 second (FEV1) (1.71-1.98 L, P = 0.001). There were no significant differences in percent-predicted values for FVC (69%-66%, P = 0.51) or FEV1 (64%-63%, P = 0.77). In adult patients, there were no significant changes in FVC (2.73-2.61 L, P = 0.35) or FEV1 (2.22-2.07 L, P = 0.51) after PVCR; also, changes in adult percent-predicted values for FVC (79%-76%, P = 0.47) and FEV1 (78%-74%, P = 0.40) were not significant. In pediatric patients who underwent PVCR, improved PFTs were correlated with younger age (P = 0.02), diagnosis of angular kyphosis (P ≤ 0.0001), no previous spine surgery (P = 0.04), and preoperative halo-gravity traction (P = 0.02). Comparison of PFT changes between patients who underwent PVCR and a control group who underwent combined anterior/posterior approaches revealed no significant differences. In pediatric patients, PVCR resulted in small but significant improvements in postoperative FVC and FEV1. In adult patients, no significant increases in PFTs were found. Patients who have the greatest potential for lung and thoracic cage growth after spinal correction are most likely to have improved pulmonary function after PVCR.

OBJECTIVE Previous meta-analysis has demonstrated that the most important factor in seizure freedom following surgery for focal cortical dysplasia (FCD) is completeness of resection. However, intraoperative detection of epileptogenic dysplastic cortical tissue remains a challenge, potentially leading to a partial resection and the need for reoperation. The objective of this study was to determine the role of intraoperative MRI (iMRI) in the intraoperative detection and localization of FCD as well as its impact on surgical decision making, completeness of resection, and seizure control outcomes. METHODS The authors retrospectively reviewed the medical records of pediatric patients who underwent iMRI-assisted resection of FCD at the Children's National Health System between January 2014 and April 2015. Data reviewed included demographics, length of surgery, details of iMRI acquisition, postoperative seizure freedom, and complications. Postsurgical seizure outcome was assessed utilizing the Engel Epilepsy Surgery Outcome Scale. RESULTS Twelve consecutive pediatric patients (8 females and 4 males) underwent iMRI-guided resection of FCD lesions. The mean age at the time of surgery was 8.8 years ± 1.6 years (range 0.7 to 18.8 years), and the mean duration of follow up was 3.5 months ± 1.0 month. The mean age at seizure onset was 2.8 years ± 1.0 year (range birth to 9.0 years). Two patients had Type 1 FCD, 5 patients had Type 2A FCD, 2 patients had Type 2B FCD, and 3 patients had FCD of undetermined classification. iMRI findings impacted intraoperative surgical decision making in 5 (42%) of the 12 patients, who then underwent further exploration of the resection cavity. At the time of the last postoperative follow-up, 11 (92%) of the 12 patients were seizure free (Engel Class I). No patients underwent reoperation following iMRI-guided surgery. CONCLUSIONS iMRI-guided resection of FCD in pediatric patients precluded the need for repeat surgery. Furthermore, it resulted in the achievement of complete resection in all the patients, leading to a high rate of postoperative seizure freedom.

The relative effectiveness of GlideScope(®) videolaryngoscopy (GV) for nasotracheal intubation in pediatric patients is unclear. The purpose of this study is to evaluate the usefulness of GV for nasotracheal intubation compared with direct laryngoscopy (DL) in pediatric patients. Our patient cohort consisted of 80 children <10 years of age who required nasotracheal intubation for elective dental or facial surgery. The patients were randomly allocated to GV (n = 40) or DL (n = 40) group. The time to intubation (TTI), glottic view grade, frequency of Magill forceps use, and degree of difficulty in intubation were evaluated. The median TTI was similar between the groups. The TTI of the former 20 patients was faster in the DL group (53.3 s, interquartile range: 42.0-64.3) than GV group (65.9 s, interquartile range: 56.0-93.9) (P = 0.007), whereas the TTI of the latter 20 patients was comparable between the groups. There were no significant differences in glottic view grade, frequency of Magill forceps use, and degree of difficulty in intubation between the two groups. GV can provide similar intubation performance characteristics compared with DL when used for nasotracheal intubation in pediatric patients. However, experience is needed to be skillful in the GV to acquire comparable TTI with DL. © 2011 Blackwell Publishing Ltd.

ABSTRACT Purpose: To describe our experience utilizing Laparoendoscopic single site (LESS) surgery in pediatric urology. Materials and Methods: Retrospective chart review was performed on LESS urologic procedures from November 2009 through March 2013. A total of 44 patients underwent 54 procedures including: nephrectomy (23), orchiopexy (14), varicocelectomy (9), orchiectomy (2), urachal cyst excision (3), and antegrade continence enema (3) (ACE). Results: Median patient age was 6.9 years old. Estimated blood loss (EBL), ranged from less than 5cc to 47cc for a bilateral nephrectomy. Operative time varied from 56 mins for varicocelectomy to a median of 360 minutes for a bilateral nephroureterectomy. Incision length ranged between 2 and 2.5cm. In our initial experience we used a commercial port. However, as we progressed, we were able to perform the majority of our procedures via adjacent fascial punctures for instrumentation at the single incision site. One patient did require conversion to an open procedure as a result of bleeding. Three complications were noted (6.8%), with two Clavien Grade 3b complications. Two patients required additional procedures at 1-year follow-up. Conclusions: The use of LESS applies to many pediatric urologic procedures, ideally for ablative procedures or simple reconstructive efforts. The use of adjacent fascial puncture sites for instrumentation can obviate the need for a commercial port or multiple trocars. PMID:27256182

The aim of the study was to describe and assess the technical success and safety of ultrasound-guided liver biopsy with gelatin sponge pledget tract embolization technique in infants <10 kg across 3 tertiary pediatric hospitals. There were 67 pediatric patients weighing <10 kg (36 boys; 31 girls; average age 202 days; average weight 6 kg, range 1.5-9.9 kg) referred for liver biopsy performed with ultrasound guidance and gelatin sponge pledget tract embolization during a 2-year period. Patient history, procedural records, and clinical follow-up documents were retrospectively reviewed. A total of 67 procedures were included. There was 100% technical success rate and all samples obtained provided adequate tissue for histological assessment. Average number of 18 G biopsy passes was 3 (range 1-6). There were no procedure-related deaths. There was 1 complication (1%) in a 5-kg infant who was readmitted 36 hours after biopsy with a fever and fully recovered after antibiotics were administered. Biliary atresia was the most common underlying diagnosis (20%), whereas others included acute rejection (16%) and biliary obstruction (7%). Ultrasound-guided percutaneous liver biopsy with gelatin sponge pledget tract embolization technique in children weighing <10 kg is safe, effective, and use of this technique may lead to a reduction in rates of adverse events reported in other pediatric series.

Outlining specific protocols for the management of pediatric patients with Marfan syndrome has been challenging. This is mostly due to a dearth of clinical studies performed in pediatric patients. In Marfan syndrome, the major sources of morbidity and mortality relate to the cardiovascular system. In this review, we focus on aortic involvement seen in pediatric patients with Marfan syndrome, ranging from aortic dilatation to aortic rupture and heart failure. We discuss the histological, morphological, and pathogenetic basis of the cardiac manifestations seen in pediatric Marfan syndrome and use a specific case to depict our experienced range of cardiovascular manifestations. The survival for patients with Marfan syndrome may approach the expected survival for non-affected patients, with optimal management. With this potentiality in mind, we explore possible and actual management considerations for pediatric Marfan syndrome, examining both medical and surgical therapy modalities that can make the possibility of improved survival a reality.

A workforce analysis was conducted to predict whether the projected future supply of pediatric anesthesiologists is balanced with the requirements of the inpatient pediatric population. The specific aims of our analysis were to (1) project the number of pediatric anesthesiologists in the future workforce; (2) project pediatric anesthesiologist-to-pediatric population ratios (0-17 years); (3) project the mean number of inpatient pediatric procedures per pediatric anesthesiologist; and (4) evaluate the effect of alternative projections of individual variables on the model projections through 2035. The future number of pediatric anesthesiologists is determined by the current supply, additions to the workforce, and departures from the workforce. We previously compiled a database of US pediatric anesthesiologists in the base year of 2015. The historical linear growth rate for pediatric anesthesiology fellowship positions was determined using the Accreditation Council for Graduate Medical Education Data Resource Books from 2002 to 2016. The future number of pediatric anesthesiologists in the workforce was projected given growth of pediatric anesthesiology fellowship positions at the historical linear growth rate, modeling that 75% of graduating fellows remain in the pediatric anesthesiology workforce, and anesthesiologists retire at the current mean retirement age of 64 years old. The baseline model projections were accompanied by age- and gender-adjusted anesthesiologist supply, and sensitivity analyses of potential variations in fellowship position growth, retirement, pediatric population, inpatient surgery, and market share to evaluate the effect of each model variable on the baseline model. The projected ratio of pediatric anesthesiologists to pediatric population was determined using the 2012 US Census pediatric population projections. The projected number of inpatient pediatric procedures per pediatric anesthesiologist was determined using the Kids' Inpatient Database historical data to project the future number of inpatient procedures (including out of operating room procedures). In 2015, there were 5.4 pediatric anesthesiologists per 100,000 pediatric population and a mean (±standard deviation [SD]) of 262 ±8 inpatient procedures per pediatric anesthesiologist. If historical trends continue, there will be an estimated 7.4 pediatric anesthesiologists per 100,000 pediatric population and a mean (±SD) 193 ±6 inpatient procedures per pediatric anesthesiologist in 2035. If pediatric anesthesiology fellowship positions plateau at 2015 levels, there will be an estimated 5.7 pediatric anesthesiologists per 100,000 pediatric population and a mean (±SD) 248 ±7 inpatient procedures per pediatric anesthesiologist in 2035. If historical trends continue, the growth in pediatric anesthesiologist supply may exceed the growth in both the pediatric population and inpatient procedures in the 20-year period from 2015 to 2035.

The differences between pediatric (< or = 17 years of age) and adult clinical field encounters were analyzed from four deployments of Disaster Medical Assistance Teams (DMATs). A retrospective cohort review of all patients who presented to DMAT field clinics during two hurricanes, one earthquake, and one flood was conducted. Descriptive statistics were used to analyze: (1) age; (2) gender; (3) severity category level; (4) chief complaint; (5) treatments provided; (6) discharge diagnosis; and (7) disposition. Five subsets of pediatric patients were analyzed further. Of the 2,196 patient encounters reviewed, 643 (29.5%) encounters were pediatric patients. Pediatric patients had a greater number of blank severity category levels than adults. Pediatric patients also were: (1) more likely to present with chief complaints of upper respiratory infections or wounds; (2) less likely to present with musculoskeletal pain or abdominal pain; and (3) equally likely to present with rashes. Pediatric patients were more likely to receive antibiotics, pain medication, and antihistamines, but were equally likely to need treatment for wounds. Dispositions to the hospital were less frequent for pediatric patients than for adults. Pediatric patients represent a substantial proportion of disaster victims at DMAT field clinics. They often necessitate special care requirements different from their adult counterparts. Pediatric-specific severity category criteria, treatment guidelines, equipment/medication stocks, and provider training are warranted for future DMAT response preparations.

Population models can be important extensions of therapeutic drug monitoring (TDM), as they allow estimation of individual pharmacokinetic parameters based on a small number of measured drug concentrations. This study used a Bayesian approach to explore the utility of routinely collected and sparse TDM data (1 sample per patient) for carbamazepine (CBZ) monotherapy in developing a population pharmacokinetic (PPK) model for CBZ in pediatric patients that would allow prediction of CBZ concentrations for both immediate- and controlled-release formulations. Patient and TDM data were obtained from a pediatric neurology outpatient database. Data were analyzed using an iterative 2-stage Bayesian algorithm and a nonparametric adaptive grid algorithm. Models were compared by final log likelihood, mean error (ME) as a measure of bias, and root mean squared error (RMSE) as a measure of precision. Fifty-seven entries with data on CBZ monotherapy were identified from the database and used in the analysis (36 from males, 21 from females; mean [SD] age, 9.1 [4.4] years [range, 2-21 years]). Preliminary models estimating clearance (Cl) or the elimination rate constant (K(el)) gave good prediction of serum concentrations compared with measured serum concentrations, but estimates of Cl and K(el) were highly correlated with estimates of volume of distribution (V(d)). Different covariate models were then tested. The selected model had zero-order input and had age and body weight as covariates. Cl (L/h) was calculated as K(el) . V(d), where K(el) = [K(i) - (K(s) . age)] and V(d) = [V(i) + (V(s) . body weight)]. Median parameter estimates were V(i) (intercept) = 11.5 L (fixed); V(s) (slope) = 0.3957 L/kg (range, 0.01200-1.5730); K(i) (intercept) = 0.173 h(-1) (fixed); and K(s) (slope) = 0.004487 h(-1) . y(-1) (range, 0.0001800-0.02969). The fit was good for estimates of steady-state serum concentrations based on prior values (population median estimates) (R = 0.468; R(2) = 0.219) but was even better for predictions based on individual Bayesian posterior values (R(2) = 0.991), with little bias (ME = -0.079) and good precision (RMSE = 0.055). Based on the findings of this study, sparse TDM data can be used for PPK modeling of CBZ clearance in children with epilepsy, and these models can be used to predict Cl at steady state in pediatric patients. However, to estimate additional pharmacokinetic model parameters (eg, the absorption rate constant and V(d)), it would be necessary to combine sparse TDM data with additional well-timed samples. This would allow development of more informative PPK models that could be used as part of Bayesian dose-individualization strategies.

Does pediatric body mass index affect surgical outcomes of lower-extremity external fixation?

2015-06-01

Obese patients are highly prevalent in the pediatric orthopaedic surgeon's practice and obesity is an increasing issue in the United States. Increased body mass index (BMI) has been associated with increased complications in pediatric orthopaedic patients, but no study has looked specifically at external fixation. The purpose of this study was to determine whether obesity is a risk factor for increased complications in lower-extremity procedures requiring external fixation. A retrospective chart review was conducted of pediatric patients who underwent external fixation as definitive operative treatment for any condition at a tertiary care hospital over a 15-year period. Patients were grouped into normal weight, overweight, and obese based on Centers for Disease Control definitions. All orthopaedic complications were recorded. A total of 208 patients with a mean age of 11.2 years were identified. Ninety-four children were obese at the 95th percentile BMI or higher, 22 were overweight and 93 were normal weight. External fixation was applied to the tibia in 82 cases, to the femur in 77 and to both in 49. Mean duration of fixation was 160 days (range, 31 to 570 d) and patients were followed for a mean of 3.9 years (range, 1.0 to 12.0 y). There was no statistically significant difference in the rate of complications between the 3 groups (P=0.61). In the obese group complications occurred in 68.1% versus 66.7% in the overweight group and 61.3% in normal weight. In the setting of external fixator use for lower-extremity pathology in pediatric patients, there is no association between an increase in complications and obesity as defined by BMI. Complication rates are high when external fixation is utilized for the lower extremity, however, patients and families should not be counseled that increased BMI will add to the burden of orthopaedic complications in this situation.

The study aims were to compare two models (The Pediatric Risk of Mortality III (PRISM III) and Pediatric Logistic Organ Dysfunction (PELOD-2)) for prediction of mortality in a pediatric intensive care unit (PICU) and recalibrate PELOD-2 in a Portuguese population. To achieve the previous goal, a prospective cohort study to evaluate score performance (standardized mortality ratio, discrimination, and calibration) for both models was performed. A total of 556 patients consecutively admitted to our PICU between January 2011 and December 2012 were included in the analysis. The median age was 65 months, with an interquartile range of 1 month to 17 years. The male-to-female ratio was 1.5. The median length of PICU stay was 3 days. The overall predicted number of deaths using PRISM III score was 30.8 patients whereas that by PELOD-2 was 22.1 patients. The observed mortality was 29 patients. The area under the receiver operating characteristics curve for the two models was 0.92 and 0.94, respectively. The Hosmer and Lemeshow goodness-of-fit test showed a good calibration only for PRISM III (PRISM III: χ (2) = 3.820, p = 0.282; PELOD-2: χ (2) = 9.576, p = 0.022). Both scores had good discrimination. PELOD-2 needs recalibration to be a better reliable prediction tool. • PRISM III (Pediatric Risk of Mortality III) and PELOD (Pediatric Logistic Organ Dysfunction) scores are frequently used to assess the performance of intensive care units and also for mortality prediction in the pediatric population. • Pediatric Logistic Organ Dysfunction 2 is the newer version of PELOD and has recently been validated with good discrimination and calibration. What is New: • In our population, both scores had good discrimination. • PELOD-2 needs recalibration to be a better reliable prediction tool.

Proton beams used for radiotherapy will produce neutrons when interacting with matter. The purpose of this study was to quantify the equivalent dose to tissue due to secondary neutrons in pediatric and adult patients treated by proton therapy for brain lesions. Assessment of the equivalent dose to organs away from the target requires whole-body geometrical information. Furthermore, because the patient geometry depends on age at exposure, age-dependent representations are also needed. We implemented age-dependent phantoms into our proton Monte Carlo dose calculation environment. We considered eight typical radiation fields, two of which had been previously used to treat pediatric patients. The other six fields were additionally considered to allow a systematic study of equivalent doses as a function of field parameters. For all phantoms and all fields, we simulated organ-specific equivalent neutron doses and analyzed for each organ (1) the equivalent dose due to neutrons as a function of distance to the target; (2) the equivalent dose due to neutrons as a function of patient age; (3) the equivalent dose due to neutrons as a function of field parameters; and (4) the ratio of contributions to secondary dose from the treatment head versus the contribution from the patient's body tissues. This work reports organ-specific equivalent neutron doses for up to 48 organs in a patient. We demonstrate quantitatively how organ equivalent doses for adult and pediatric patients vary as a function of patient's age, organ and field parameters. Neutron doses increase with increasing range and modulation width but decrease with field size (as defined by the aperture). We analyzed the ratio of neutron dose contributions from the patient and from the treatment head, and found that neutron-equivalent doses fall off rapidly as a function of distance from the target, in agreement with experimental data. It appears that for the fields used in this study, the neutron dose lateral to the field is smaller than the reported scattered photon doses in a typical intensity-modulated photon treatment. Most importantly, our study shows that neutron doses to specific organs depend considerably on the patient's age and body stature. The younger the patient, the higher the dose deposited due to neutrons. Given the fact that the risk also increases with decreasing patient age, this factor needs to be taken into account when treating pediatric patients of very young ages and/or of small body size. The neutron dose from a course of proton therapy treatment (assuming 70 Gy in 30 fractions) could potentially (depending on patient's age, organ, treatment site and area of CT scan) be equivalent to up to ~30 CT scans.

During LTX, there may be a risk that pathogens of the native liver are released into the systemic circulation. No investigations on incidence/spectrum of pathogens in native livers have been published. We hypothesized that pathogens are found in the native liver of a large proportion of pediatric patients during LTX and investigated the microbiology of native livers. These data may help optimize antibiotic therapy. Twenty-two consecutive pediatric patients (median age 14 months, range, 5 months-15 yr) receiving LTX in our department from October 2010 to October 2011 were included in this prospective study. Tissue and bile were collected from the explanted liver and were cultivated on different media. All liver tissues were investigated using a broad-range PCR (SepsiTest(®)). In 16 patients, blood cultures were collected post-transplantation. Eleven patients (50%) had at least one pathogen detected; nine of these patients had an underlying diagnosis of biliary atresia. SepsiTest(®) was positive in seven patients. In four patients it was the only test detecting any pathogen. In detail, the positivity rate for liver tissue in all patients was 41% (n = 9); for bile 25% (n = 3); and for blood 25% (n = 4). Thirteen different pathogens (69% bacterial, 31% fungal) were isolated. A highly-sensitive broad-range PCR appears to be an effective method to detect pathogens in native livers of patients undergoing LTX. A high number and variety of microbes, including a high proportion of fungal pathogens, were detected. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The O-arm ® navigation system allows intraoperative CT imaging that can facilitate highly accurate instrumentation surgery, but radiation exposure is higher than with X-ray radiography. This is a particular concern in pediatric surgery. The purpose of this study is to examine intraoperative radiation exposure in pediatric spinal scoliosis surgery using O-arm. The subjects were 38 consecutive patients (mean age 12.9 years, range 10-17) with scoliosis who underwent spinal surgery with posterior instrumentation using O-arm. The mean number of fused vertebral levels was 11.0 (6-15). O-arm was performed before and after screw insertion, using an original protocol for the cervical, thoracic, and lumbar spine doses. The average scanning range was 6.9 (5-9) intervertebral levels per scan, with 2-7 scans per patient (mean 4.0 scans). Using O-arm, the dose per scan was 92.5 (44-130) mGy, and the mean total dose was 401 (170-826) mGy. This dose was 80.2% of the mean preoperative CT dose of 460 (231-736) mGy (P = 0.11). The total exposure dose and number of scans using intraoperative O-arm correlated strongly and significantly with the number of fused levels; however, there was no correlation with the patient's height. As the fused range became wider, several scans were required for O-arm, and the total radiation exposure became roughly the same as that in preoperative CT. Use of O-arm in our original protocol can contribute to reduction in radiation exposure.

Pneumocystis jirovecii pneumonia occurs in various immunocompromised patients. Despite the prophylaxis strategies in clinical practice, certain patients develop P. jirovecii pneumonia. This study was performed to investigate pediatric cases with P. jirovecii pneumonia in a single center. We identified pediatric patients younger than 19 years with microbiologically confirmed P. jirovecii pneumonia from January 2000 to February 2014. A retrospective chart review was performed. Fifteen episodes of P. jirovecii pneumonia in 14 patients were identified with median age of 8.3 years (range, 0.4-18.6 years). Among these patients, 11 patients had hematology-oncology diseases, 2 had primary immunodeficiency disorders (one with severe combined immunodeficiency and the other with Wiskott Aldrich syndrome), 1 had systemic lupus erythematosus and 1 received kidney transplant. Four patients were transplant recipients; 1 allogeneic and 2 autologous hematopoietic cell transplant and 1 with kidney transplant. The median absolute lymphocyte count at the diagnosis of P. jirovecii pneumonia was 5,156 cells/mm(3) (range, 20-5,111 cells/mm(3)). In 13 episodes (13 of 15, 86.7%), patients were not receiving prophylaxis at the onset of P. jirovecii pneumonia. For treatment, trimethoprim/sulfamethoxazole was given as a main therapeutic agent in all 15 episodes. Steroid was given in 9 episodes (60%). Median treatment duration was 15 days (range, 4-33 days). Overall mortality at 60 days was 35.7% (5 of 14). Majority of our patients developed P. jirovecii pneumonia while not on prophylaxis. Continuous efforts and more data are needed to identify high risk patients who may get benefit from P. jirovecii pneumonia prophylaxis.

To describe the use and determine the prevalence of off-label and unlicensed drug use prescribing in a pediatric intensive care unit in a Southeastern Brazilian hospital Cross-sectional study of inpatients in a pediatric intensive care unit from May 2008 through January 2009. The classification according to the Brazilian regulatory agency (Agência de Vigilância Sanitária - Anvisa) approval criteria was based on the Anvisa electronic package insert list, Pharmaceuticals Dictionary, and the analysis was conducted through R software. We analysed 1,054 prescription items for 73 patients. Females predominated (52%), and the patients' age ranged from 0 to 16 years. Among the prescribed items, 23.4% were off-label, 12.6% were unlicensed, 1.4% were both off-label and unlicensed, 86% had at least one item off-label, and 67% had at least one unlicensed drug. The most frequently prescribed therapeutic groups were systemic anti-bacterial, analgesic, psycholeptic, and antiasmathic agents. The current study results confirm the high prevalence of unlicensed and off-label drug use in a pediatric intensive care unit.

Pharmacological sedation is an alternative behavior management strategy in pediatric dentistry. The aim of this study was to compare the behavioral and physiologic effects of “commercially midazolam syrup” versus “orally administered IV midazolam dosage form (extemporaneous midazolam (EF))” in uncooperative pediatric dental patients. Eighty-eight children between 4 to 7 years of age received 0.2–0.5 mg/kg midazolam in this parallel trial. Physiologic parameters were recorded at baseline and every 15 minutes. Behavior assessment was conducted objectively by Houpt scale throughout the sedation and North Carolina at baseline and during injection and cavity preparation. No significant difference in behavior was noted by Houpt or North Carolina scale. Acceptable behavior (excellent, very good, and good) was observed in 90.9% of syrup and 79.5% of EF subjects, respectively. Physiological parameters remained in normal range without significant difference between groups and no adverse effect was observed. It is concluded that EF midazolam preparation can be used as an acceptable alternative to midazolam syrup. PMID:26120325

Pediatric magnet ingestions are increasing. Commercial availability of rare-earth magnets poses a serious health risk. This study defines incidence, characteristics, and management of ingestions over time. Cases were identified by searching radiology reports from June 2002 to December 2012 at a children's hospital and verified by chart and imaging review. Relative risk (RR) regressions determined changes in incidence and interventions over time. In all, 98% of ingestions occurred since 2006; 57% involved multiple magnets. Median age was 8 years (range 0 to 18); 0% of single and 56% of multiple ingestions required intervention. Compared with 2007 to 2009, ingestions increased from 2010 to 2012 (RR = 1.9, 95% confidence interval 1.2 to 3.0). Intervention proportion was unchanged (RR = .94, 95% confidence interval .4 to 2.2). Small spherical magnets comprised 26.8% of ingestions since 2010; 86% involved multiple magnets and 47% required intervention. Pediatric magnet ingestions and interventions have increased. Multiple ingestions prompt more imaging and surgical interventions. Magnet safety standards are needed to decrease risk to children. Copyright © 2014 Elsevier Inc. All rights reserved.

Defining pediatric reference intervals is one of the most difficult tasks for laboratory physicians. The continuously changing physiology of growing children makes their laboratory values moving targets. In addition, ethnic and behavioral differences might also cause variations. The aim of this study was to establish age- and sex-specific partitioned reference intervals for 13 serum biochemical analytes in Korean children. A total of 2474 patients, girls aged 2-14 years and boys aged 2-16 years, who underwent a short stature workup but were diagnosed as normal at the Pediatric Endocrinology Clinic of Severance Hospital (Seoul, Korea) between September 2010 and June 2012 were included in this study. The levels of serum calcium, inorganic phosphorus, blood urea nitrogen, creatinine, uric acid, glucose, total cholesterol, total protein, albumin, alkaline phosphatase, aspartic aminotransferase, alanine aminotransferase, and total bilirubin were measured using a Hitachi 7600 analyzer (Hitachi High-Technologies Corporation, Tokyo, Japan). Reference intervals were partitioned according to sex or age subgroups using the Harris and Boyd method. Most analytes except calcium and albumin required partitioning either by sex or age. Age-specific partitioned reference intervals for alkaline phosphatase, creatinine, and total bilirubin were established for both males and females after being partitioned by sex. Additional age-specific partitioning of aspartic aminotransferase in females and total protein and uric acid in males was also required. Inorganic phosphorus, total cholesterol, alanine aminotransferase, blood urea nitrogen, and glucose were partitioned only by sex. This study provided updated age- and sex-specific pediatric reference intervals for 13 basic serum chemistry analytes from a sufficient number of healthy children by using a modern analytical chemistry platform.

Abstract Determining the factors modulating the genetic diversity of HIV-1 populations is essential to understand viral evolution. This study analyzes the relative importance of clinical factors in the intrahost HIV-1 subtype B (HIV-1B) evolution and in the fixation of drug resistance mutations (DRM) during longitudinal pediatric HIV-1 infection. We recovered 162 partial HIV-1B pol sequences (from 3 to 24 per patient) from 24 perinatally infected patients from the Madrid Cohort of HIV-1 infected children and adolescents in a time interval ranging from 2.2 to 20.3 years. We applied machine learning classification methods to analyze the relative importance of 28 clinical/epidemiological/virological factors in the HIV-1B evolution to predict HIV-1B genetic diversity (d), nonsynonymous and synonymous mutations (dN, dS) and DRM presence. Most of the 24 HIV-1B infected pediatric patients were Spanish (91.7%), diagnosed before 2000 (83.3%), and all were antiretroviral therapy experienced. They had from 0.3 to 18.8 years of HIV-1 exposure at sampling time. Most sequences presented DRM. The best-predictor variables for HIV-1B evolutionary parameters were the age of HIV-1 diagnosis for d, the age at first antiretroviral treatment for dN and the year of HIV-1 diagnosis for ds. The year of infection (birth year) and year of sampling seemed to be relevant for fixation of both DRM at large and, considering drug families, to protease inhibitors (PI). This study identifies, for the first time using machine learning, the factors affecting more HIV-1B pol evolution and those affecting DRM fixation in HIV-1B infected pediatric patients.

To describe the presentation, treatment, and outcomes of benign fibro-osseous tumors involving the skull base in a pediatric population. Retrospective chart review from January 2002 to September 2013 of pediatric patients (ages 0-18 years) who underwent endoscopic endonasal surgery (EES) for benign fibro-osseous tumors involving the skull base. Fourteen patients were identified with an age range of 2.7 to 17.9 years (mean, 12.5 years). Six juvenile ossifying fibromas, five benign fibro-osseous lesions, two osteomas, and one fibrous dysplasia were treated. Ocular symptoms and nasal obstruction were the most common presenting symptoms in nine (64%) and six (43%) of patients, respectively; five (36%) presented with proptosis and four (29%) with diplopia. Two (14%) patients had cranial nerve VI palsy. Transsellar and transclival approaches were used in five (36%) of patients. Orbital and optic nerve decompressions were the most common components of the approaches performed in nine (64%) of the surgeries. Gross total resection (GTR) was achieved with single-stage surgery in 10 (71%) patients; two additional patients underwent staged GTR. Two intraoperative cerebrospinal fluid (CSF) leaks occurred and were repaired endoscopically. There were no postoperative CSF leaks or infectious complications. Two patients had transient diplopia, and two had transient diabetes insipidus, all of which resolved. The mean follow-up was 13.8 months. Two patients had a recurrence, and both required additional EES achieving GTR. EES for benign fibro-osseous tumors of the skull base is a safe and effective treatment for excision of these lesions in the pediatric population. 4. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

Abusive head trauma is a severe form of child abuse. One important diagnostic finding is the presence of a subdural hematoma. Age determination of subdural hematomas is important to relate radiological findings to the clinical history presented by the caregivers. In court this topic is relevant as dating subdural hematomas can lead to identification of a suspect. The aim of our study is to describe the current practice among radiologists in the Netherlands regarding the age determination of subdural hematomas in children. This is a cross-sectional study, describing the results of an online questionnaire regarding dating subdural hematomas among pediatric and neuro-radiologists in the Netherlands. The questionnaire consisted of sociodemographic questions, theoretical questions and eight pediatric cases in which the participants were asked to date subdural hematomas based on imaging findings. Fifty-one out of 172 radiologists (30 %) filled out the questionnaire. The percentage of participants that reported it was possible to date the subdural hematoma varied between 58 and 90 % for the eight different cases. In four of eight cases (50 %), the age of the subdural hematoma as known from clinical history fell within the range reported by the participants. None of the participants was "very certain" of their age determination. The results demonstrate that there is a considerable practice variation among Dutch radiologists regarding the age determination of subdural hematomas. This implicates that dating of subdural hematomas is not suitable to use in court, as no uniformity among experts exists.

Pediatric burn patients warrant thorough evaluation because a sizeable proportion of pediatric burns are nonaccidental. A multidisciplinary method involving an internal child protection team (CPT) was developed and used to identify suspected nonaccidental pediatric burns in all pediatric burn patients 5 years of age or younger who were evaluated by the CPT and social workers at our institution over a 55-month period. We identified 343 cases for review that fit our age criteria, 6 of which we identified as cases of suspected abuse or neglect. On average, these patients were younger, suffered greater total body surface area burns (TBSA), and required a longer length of stay in the hospital than the total population. We have not had readmissions for repeat nonaccidental pediatric burn injuries in this group of patients since this model was implemented. Our multidisciplinary method might provide a more consistent and reliable method for identifying cases of suspected abuse. © 2018 American Medical Association. All Rights Reserved.

Pediatric maxillofacial fractures.

PubMed

Spring, P M; Cote, D N

1996-05-01

Maxillofacial trauma in the pediatric population is a relatively infrequent occurrence. Studies have demonstrated consistently that 5% of all facial fractures occur in children. The low percentage of facial fractures in this age group has been attributed, in part, to the lack of full pneumatization of the sinuses until later in childhood. Review of the literature indicates that boys are more commonly affected than girls and that the majority of pediatric facial fractures occur in children between 6 and 12 years of age. Motor vehicle accidents, falls, and blunt trauma are responsible for the largest number of pediatric facial fractures. The most common site of facial fracture is the nose and dentoalveolan complex, followed by the mandible, orbit, and midface in most pediatric cohorts. Management of the mandible is often conservative owing to the high percentage of isolated condylar fractures in children. Open reduction and internal fixation of pediatric facial fractures is indicated in complex mandible, midface, and orbital fractures. The effect of rigid fixation on facial skeleton growth is not completely understood.

Although rare, the incidence of venous thromboembolism (VTE) in pediatric trauma patients is increasing, and the consequences of VTE in children are significant. Studies have demonstrated increasing VTE risk in older pediatric trauma patients and improved VTE rates with institutional interventions. While national evidence-based guidelines for VTE screening and prevention are in place for adults, none exist for pediatric patients, to our knowledge. To develop a risk prediction calculator for VTE in children admitted to the hospital after traumatic injury to assist efforts in developing screening and prophylaxis guidelines for this population. Retrospective review of 536,423 pediatric patients 0 to 17 years old using the National Trauma Data Bank from January 1, 2007, to December 31, 2012. Five mixed-effects logistic regression models of varying complexity were fit on a training data set. Model validity was determined by comparison of the area under the receiver operating characteristic curve (AUROC) for the training and validation data sets from the original model fit. A clinical tool to predict the risk of VTE based on individual patient clinical characteristics was developed from the optimal model. Diagnosis of VTE during hospital admission. Venous thromboembolism was diagnosed in 1141 of 536,423 children (overall rate, 0.2%). The AUROCs in the training data set were high (range, 0.873-0.946) for each model, with minimal AUROC attenuation in the validation data set. A prediction tool was developed from a model that achieved a balance of high performance (AUROCs, 0.945 and 0.932 in the training and validation data sets, respectively; P = .048) and parsimony. Points are assigned to each variable considered (Glasgow Coma Scale score, age, sex, intensive care unit admission, intubation, transfusion of blood products, central venous catheter placement, presence of pelvic or lower extremity fractures, and major surgery), and the points total is converted to a VTE risk score. The predicted risk of VTE ranged from 0.0% to 14.4%. We developed a simple clinical tool to predict the risk of developing VTE in pediatric trauma patients. It is based on a model created using a large national database and was internally validated. The clinical tool requires external validation but provides an initial step toward the development of the specific VTE protocols for pediatric trauma patients.

AIM To study implications of measuring quality indicators on training and trainees’ performance in pediatric colonoscopy in a low-volume training center. METHODS We reviewed retrospectively the performance of pediatric colonoscopies in a training center in Malaysia over 5 years (January 2010-December 2015), benchmarked against five quality indicators: appropriateness of indications, bowel preparations, cecum and ileal examination rates, and complications. The European Society of Gastrointestinal Endoscopy guideline for pediatric endoscopy and North American Society for Pediatric Gastroenterology, Hepatology and Nutrition training guidelines were used as benchmarks. RESULTS Median (± SD) age of 121 children [males = 74 (61.2%)] who had 177 colonoscopies was 7.0 (± 4.6) years. On average, 30 colonoscopies were performed each year (range: 19-58). Except for investigations of abdominal pain (21/177, 17%), indications for colonoscopies were appropriate in the remaining 83%. Bowel preparation was good in 87%. One patient (0.6%) with severe Crohn’s disease had bowel perforation. Cecum examination and ileal intubation rate was 95% and 68.1%. Ileal intubation rate was significantly higher in diagnosing or assessing inflammatory bowel disease (IBD) than non-IBD (72.9% vs 50.0% P = 0.016). Performance of four trainees was consistent throughout the study period. Average cecum and ileal examination rate among trainees were 97% and 77%. CONCLUSION Benchmarking against established guidelines helps units with a low-volume of colonoscopies to identify area for further improvement. PMID:29531465

The aim of this study was to compare the results of enhanced Brückner test (EBT) performed by a pediatrician and an experienced pediatric ophthalmologist. In this prospective double-masked cohort study, a pediatrician and a pediatric ophthalmologist performed the EBT in a classroom of a school in semi-dark lighting condition using a direct ophthalmoscope. The results of the test were compared using 2 × 2 Bayesian table and kappa statistics. The findings of the pediatric ophthalmologists were considered gold standard. Two hundred and thirty-six eyes of 118 subjects, mean age 6.8 ± 0.5 years (range, 5.4-7.8 years), were examined. The time taken to complete this test was <10 s per subject. The ophthalmologist identified 59 eyes as ametropic (12 hyperopic and 47 myopic eyes) and 177 as emmetropic compared to 61 eyes as ametropic and 175 emmetropic by pediatrician. The prevalence of the test positive was 25.9%. The sensitivity of the pediatrician was 90.2%, specificity was 97.7%, predictive value of the positive test was 93.2%, and predictive value of the negative test was 96.6%. The clinical agreement (kappa) between the pediatric ophthalmologist and the pediatrician was 0.9. The results of the EBT performed by pediatrician were comparable to that of an experienced pediatric ophthalmologist. Opportunistic screening of refractive errors using EBT by a pediatrician can be an important approach in the detection of ametropia in children.

Epidemiology of pediatric obstructive sleep apnea.

Lumeng, Julie C; Chervin, Ronald D

2008-02-15

Pediatric obstructive sleep apnea (OSA) has become widely recognized only in the last few decades as a likely cause of significant morbidity among children. Many of the clinical characteristics of pediatric OSA, and the determinants of its epidemiology, differ from those of adult OSA. We systematically reviewed studies on the epidemiology of conditions considered part of a pediatric sleep-disordered breathing (SDB) continuum, ranging from primary snoring to OSA. We highlight a number of methodologic challenges, including widely variable methodologies for collection of questionnaire data about symptomatology, definitions of habitual snoring, criteria for advancing to further diagnostic testing, and objective diagnostic criteria for SDB or OSA. In the face of these limitations, estimated population prevalences are as follows: parent-reported "always" snoring, 1.5 to 6%; parent-reported apneic events during sleep, 0.2 to 4%; SDB by varying constellations of parent-reported symptoms on questionnaire, 4 to 11%; OSA diagnosed by varying criteria on diagnostic studies, 1 to 4%. Overall prevalence of parent-reported snoring by any definition in meta-analysis was 7.45% (95% confidence interval, 5.75-9.61). A reasonable preponderance of evidence now suggests that SDB is more common among boys than girls, and among children who are heavier than others, with emerging data to suggest a higher prevalence among African Americans. Less convincing data exist to prove differences in prevalence based on age. We conclude by outlining specific future research needs in the epidemiology of pediatric SDB.

To develop the Patient Reported Outcome Measurement Information System (PROMIS) Pediatric Sleep Health item pool and evaluate its content validity. Participants included 8 expert sleep clinician-researchers, 64 children ages 8-17 years, and 54 parents of children ages 5-17 years. We started with item concepts and expressions from the PROMIS Sleep Disturbance and Sleep Related Impairment adult measures. Additional pediatric sleep health concepts were generated by expert (n = 8), child (n = 28), and parent (n = 33) concept elicitation interviews and a systematic review of existing pediatric sleep health questionnaires. Content validity of the item pool was evaluated with item translatability review, readability analysis, and child (n = 36) and parent (n = 21) cognitive interviews. The final pediatric Sleep Health item pool includes 43 items that assess sleep disturbance (children's capacity to fall and stay asleep, sleep quality, dreams, and parasomnias) and sleep-related impairments (daytime sleepiness, low energy, difficulty waking up, and the impact of sleep and sleepiness on cognition, affect, behavior, and daily activities). Items are translatable and relevant and well understood by children ages 8-17 and parents of children ages 5-17. Rigorous qualitative procedures were used to develop and evaluate the content validity of the PROMIS Pediatric Sleep Health item pool. Once the item pool's psychometric properties are established, the scales will be useful for measuring children's subjective experiences of sleep.

Earthquake-Related Injuries in the Pediatric Population: A Systematic Review

PubMed Central

Jacquet, Gabrielle A.; Hansoti, Bhakti; Vu, Alexander; Bayram, Jamil D.

2013-01-01

Background: Children are a special population, particularly susceptible to injury. Registries for various injury types in the pediatric population are important, not only for epidemiological purposes but also for their implications on intervention programs. Although injury registries already exist, there is no uniform injury classification system for traumatic mass casualty events such as earthquakes. Objective: To systematically review peer-reviewed literature on the patterns of earthquake-related injuries in the pediatric population. Methods: On May 14, 2012, the authors performed a systematic review of literature from 1950 to 2012 indexed in Pubmed, EMBASE, Scopus, Web of Science, and Cochrane Library. Articles written in English, providing a quantitative description of pediatric injuries were included. Articles focusing on other types of disasters, geological, surgical, conceptual, psychological, indirect injuries, injury complications such as wound infections and acute kidney injury, case reports, reviews, and non-English articles were excluded. Results: A total of 2037 articles were retrieved, of which only 10 contained quantitative earthquake-related pediatric injury data. All studies were retrospective, had different age categorization, and reported injuries heterogeneously. Only 2 studies reported patterns of injury for all pediatric patients, including patients admitted and discharged. Seven articles described injuries by anatomic location, 5 articles described injuries by type, and 2 articles described injuries using both systems. Conclusions: Differences in age categorization of pediatric patients, and in the injury classification system make quantifying the burden of earthquake-related injuries in the pediatric population difficult. A uniform age categorization and injury classification system are paramount for drawing broader conclusions, enhancing disaster preparation for future disasters, and decreasing morbidity and mortality.

In low- and middle-income countries, there is a gap between the need for surgery and its equitable provision, and a lack of proxy indicators to estimate this gap. Sierra Leone is a West African country with close to three million children. It is unknown to what extent the surgical needs of these children are met. To describe a nationwide provision of pediatric surgical procedures and to assess pediatric hernia repair as a proxy indicator for the shortage of surgical care in the pediatric population in Sierra Leone. We analyzed results from a nationwide facility survey in Sierra Leone that collected data on surgical procedures from operation and anesthesia logbooks in all facilities performing surgery. We included data on all patients under the age of 16 years undergoing surgery. Primary outcomes were rate and volume of surgical procedures. We calculated the expected number of inguinal hernia in children and estimated the unmet need for hernia repair. In 2012, a total of 2381 pediatric surgical procedures were performed in Sierra Leone. The rate of pediatric surgical procedures was 84 per 100,000 children 0-15 years of age. The most common pediatric surgical procedure was hernia repair (18%), corresponding to a rate of 16 per 100,000 children 0-15 years of age. The estimated unmet need for inguinal hernia repair was 88%. The rate of pediatric surgery in Sierra Leone was very low, and inguinal hernia was the single most common procedure noted among children in Sierra Leone.

Methods Cases of IIH were identified retrospectively based on diagnostic code, pediatric neuroophthalmologist databases, or both and updated diagnostic criteria (2013) were applied to confirm definite IIH. Anthropometric measurements were converted into age- and gender-specific height, weight, and BMI Z-scores CDC 2000 growth charts. When available, sexual maturation was noted. Results Two hundred thirty-three cases of definite IIH were identified across 8 sites. In boys, a moderate association between age and BMI Z-scores was noted (Pearson’s correlation coefficient, 0.50; 95% confidence interval [CI], 0.30–0.66; P < 0.001; n = 72), and in girls, a weak association was noted (Pearson’s correlation coefficient, 0.34; 95% CI, 0.20–0.47; P < 0.001; n = 161). The average patient was more likely to be overweight at diagnosis at age 6.7 years in girls and 8.7 years in boys, and obese at diagnosis at age 12.5 years in girls and 12.4 years in boys. Compared with age- and gender-matched reference values, early adolescent patients were taller for age (P = 0.002 in girls and P = 0.02 in boys). Data on Tanner staging, menarchal status, or both were available in 25% of cases (n = 57/233). Prepubertal participants (n = 12) had lower average BMI Z-scores (0.95±1.98) compared with pubertal participants (n = 45; 1.92±0.60), but this result did not reach statistical significance (P = 0.09). Conclusions With updated diagnostic criteria and pediatric-specific assessments, the present study identifies 3 subgroups of pediatric IIH: a young group that is not overweight, an early adolescent group that is either overweight or obese, and a late adolescent group that is mostly obese. Data also suggest that the early adolescent group with IIH may be taller than age- and gender-matched reference values. Understanding these features of pediatric IIH may help to illuminate the complex pathogenesis of this condition. PMID:27692528

Background The clinical value of free thyroxine (FT4) and free triiodothyronine (FT3) analysis depends on the reference intervals with which they are compared. We determined age- and sex-specific reference intervals for neonates, infants, and children 0–18 years of age for FT4 and FT3 using tandem mass spectrometry. Methods Reference intervals were calculated for serum FT4 (n = 1426) and FT3 (n = 1107) obtained from healthy children between January 1, 2008, and June 30, 2008, from Children's National Medical Center and Georgetown University Medical Center Bioanalytical Core Laboratory, Washington, DC. Serum samples were analyzed using isotope dilution liquid chromatography tandem mass spectrometry (LC/MS/MS) with deuterium-labeled internal standards. Results FT4 reference intervals were very similar for males and females of all ages and ranged between 1.3 and 2.4 ng/dL for children 1 to 18 years old. FT4 reference intervals for 1- to 12-month-old infants were 1.3–2.8 ng/dL. These 2.5 to 97.5 percentile intervals were much tighter than reference intervals obtained using immunoassay platforms 0.48–2.78 ng/dL for males and 0.85–2.09 ng/dL for females. Similarly, FT3 intervals were consistent and similar for males and females and for all ages, ranging between 1.5 pg/mL and approximately 6.0 pg/mL for children 1 month of age to 18 years old. Conclusions This is the first study to provide pediatric reference intervals of FT4 and FT3 for children from birth to 18 years of age using LC/MS/MS. Analysis using LC/MS/MS provides more specific quantification of thyroid hormones. A comparison of the ultrafiltration tandem mass spectrometric method with equilibrium dialysis showed very good correlation. PMID:19583487

To examine geographic variation in motor vehicle crash (MVC)-related pediatric mortality and identify state-level predictors of mortality. Using the 2010-2014 Fatality Analysis Reporting System, we identified passengers <15 years of age involved in fatal MVCs, defined as crashes on US public roads with ≥1 death (adult or pediatric) within 30 days. We assessed passenger, driver, vehicle, crash, and state policy characteristics as factors potentially associated with MVC-related pediatric mortality. Our outcomes were age-adjusted, MVC-related mortality rate per 100 000 children and percentage of children who died of those in fatal MVCs. Unit of analysis was US state. We used multivariable linear regression to define state characteristics associated with higher levels of each outcome. Of 18 116 children in fatal MVCs, 15.9% died. The age-adjusted, MVC-related mortality rate per 100 000 children varied from 0.25 in Massachusetts to 3.23 in Mississippi (mean national rate of 0.94). Predictors of greater age-adjusted, MVC-related mortality rate per 100 000 children included greater percentage of children who were unrestrained or inappropriately restrained (P < .001) and greater percentage of crashes on rural roads (P = .016). Additionally, greater percentages of children died in states without red light camera legislation (P < .001). For 10% absolute improvement in appropriate child restraint use nationally, our risk-adjusted model predicted >1100 pediatric deaths averted over 5 years. MVC-related pediatric mortality varied by state and was associated with restraint nonuse or misuse, rural roads, vehicle type, and red light camera policy. Revising state regulations and improving enforcement around these factors may prevent substantial pediatric mortality. Copyright © 2017 Elsevier Inc. All rights reserved.

The gray matter abnormalities revealed by magnetic resonance imaging are inconsistent, especially in pediatric individuals with autism spectrum disorder (ASD) (age < 18 years old), a phenomenon possibly related to the core pathophysiology of ASD. The purpose of our meta-analysis was to identify and map the specific gray matter abnormalities in pediatric ASD individuals thereby exploring the potential effects of clinical and demographic characteristics of these gray matter changes. A systematic search was conducted to identify voxel-based morphometry studies in pediatric individuals with ASD. The effect-size signed differential mapping method was used to quantitatively estimate the regional gray matter abnormalities in pediatric ASD individuals. Meta-regression was used to examine the associations among age, gender, intelligence quotient, symptom severity and gray matter changes. Fifteen studies including 364 pediatric individuals with ASD (male = 282, age = 10.3 ± 4.4 years) and 377 healthy controls (male = 289, age = 10.5 ± 4.2 years) were included. Pediatric ASD individuals showed significant gray matter increases in the right angular gyrus, left superior and middle frontal gyrus, left precuneus, left inferior occipital gyrus and right inferior temporal gyrus, most of which involving the default mode network, and decreases in the left cerebellum and left postcentral gyrus. The meta-regression analysis showed that the repetitive behavior scores of the Autism Diagnostic Interview-Revised were positively associated with increased gray matter volumes in the right angular gyrus. Increased rather than decreased gray matter volume, especially involving the angular gyrus and prefrontal cortex may be the core pathophysiology in the early course of ASD.

Developing a comprehensive response for treatment of children under 6 years of age with schistosomiasis: research and development of a pediatric formulation of praziquantel.

Schistosomiasis is a parasitic disease caused by blood flukes. The disease is caused by an inflammatory reaction to parasite eggs retained in the liver, bladder and reproductive organs. According to 2017 World Health Organization (WHO) estimates 220 million people are potentially infected, from which probably 10% are children under 6 years of age. The regular treatment approach of a single, oral dose of 40 mg/kg body weight with praziquantel however, is difficult for children under the age of 6, leaving them without a treatment option. In order to address this important gap in treatment target populations, an international public-private partnership that works on a not-for-profit basis in the field of drug research and development for schistosomiasis was established in 2012. This is called the Pediatric Praziquantel Consortium. Its mission was and continues to be to develop, register and provide access to a suitable pediatric praziquantel formulation for treating schistosomiasis in preschool-age children (3-6 months up to 6 years). The Target Product Profile for the pediatric formulation of praziquantel that would be suitable to treat children as young as 3-6 months was then defined by a group of experts, including members from the Pediatric Praziquantel Consortium partner organizations as well as experts from WHO (as observer) and schistosomiasis endemic countries. The development of the drug is ongoing and the Pediatric Praziquantel Consortium aims to submit the regulatory dossier for marketing approval in endemic countries and WHO prequalification in 2018/19 with approval and product launch for schistosomiasis pediatric case management in key endemic countries in 2019. Ultimately, the goal is for the product to be considered for a large-scale mass distribution program by 2022.

Studies reporting on penetrating thoracic trauma in the pediatric population have been limited by small numbers and implied differences with the adult population. Our objectives were to report on a large cohort of pediatric patients presenting with penetrating thoracic trauma and to determine age-related impacts on management and outcome through comparison with an adult cohort. A Level I trauma center registry was queried between 2006 and 2012. All patients presenting with penetrating thoracic trauma were identified. Patient demographics, injury mechanism, injury severity, admission physiology, and outcome were recorded. Patients were compared, and outcomes were analyzed based on age at presentation, with patients 17 years or younger defining our pediatric cohort. A total of 1,423 patients with penetrating thoracic trauma were admitted during the study period. Two hundred twenty patients (15.5%) were pediatric, with 205 being adolescents (13-17 years) and 15 being children (≤ 12 years). In terms of management for the pediatric population, tube thoracostomy alone was needed in 32.7% (72 of 220), whereas operative thoracic exploration was performed in 20.0% (44 of 220). Overall mortality was 13.6% (30 of 220). There was no significant difference between the pediatric and adult population with regard to injury mechanism or severity, need for therapeutic intervention, operative approach, use of emergency department thoracotomy, or outcome. Stepwise logistic regression failed to identify age as a predictor for the need for either therapeutic intervention or mortality between the two age groups as a whole. However, subgroup analysis revealed that being 12 years or younger (odds ratio, 3.84; 95% confidence interval, 1.29-11.4) was an independent predictor of mortality. Management of traumatic penetrating thoracic injuries in terms of the need for therapeutic intervention and operative approach was similar between the adult and pediatric populations. Mortality from penetrating thoracic trauma can be predicted based on injury severity, the use of emergency department thoracotomy, and admission physiology for adolescents and adults. Children may be at increased risk for poor outcome independent of injury severity. Epidemiologic study, level III.

Guidelines for the Diagnosis and Treatment of Cutaneous Mastocytosis in Children

Castells, Mariana; Metcalfe, Dean D.; Escribano, Luis

2012-01-01

Mastocytosis is a disease with many variants, all of which are characterized by a pathologic increase in mast cells in cutaneous tissue and extracutaneous organs such as the bone marrow, liver, spleen and lymph nodes. The disease presents in two primary age-related patterns: pediatric-onset mastocytosis and adult-onset mastocytosis, which may differ in their clinical manifestations and disease course. Pediatric-onset mastocytosis commonly is diagnosed prior to 2 years of age, and usually consists of cutaneous disease, with urticaria pigmentosa (UP) the most common pattern. The course of pediatric-onset mastocytosis is variable. This is in contrast to adult onset disease which generally presents with systemic findings and increases in extent and severity over time. Because pediatric forms of mastocytosis often differ in presentation and prognosis from adult variants, it is most important to understand pediatric mastocytosis and not rely on adult approaches as a guide on how to identify and manage disease. This is especially important in selecting therapy where antiproliferative agents have a very different set of concerns when used to treat adult mastocytosis compared to pediatric mastocytosis, especially in terms of long-term toxicity. This review is directed at providing age-specific information surrounding the care of the child with mastocytosis. PMID:21668033

Forty pediatric patients, ranging from 5-13 years of age and suffering from grass pollen rhinoconjunctivitis, were submitted to local nasal preseasonal (12 weeks) immunotherapy, either with a grass pollen extract or with placebo. After 1 year, 15 of these patients (5 previously treated with active product and 10 with placebo) were treated with the grass pollen extract preseasonally for 2 consecutive years. Before and after treatment, serum total IgA and IgE, and specific IgG and IgE were assayed as well as carrying out nasal provocation tests (NPT) with extracts at different concentrations, endpoint evaluations by rhinomanometry and prick tests with different concentrations of extract. After only 1 year, the actively treated patients showed a significant decrease of daily nasal and conjunctival signs and symptoms-as judged by a 1 to 3 score-in comparison with the control group. The placebo group showed the same results after the 3rd year. The improvement was confirmed by a significant increase of the dose threshold in NPT. No immunological alterations were evident.

To assess the performance of two pediatric length-based tapes (Broselow and Handtevy) in predicting actual weights of US children. In this descriptive study, weights and lengths of children (newborn through 13 years of age) were extracted from the 2009-2010 National Health and Nutrition Examination Survey (NHANES). Using the measured length ranges for each tape and the NHANES-extracted length data, every case from the study sample was coded into Broselow and Handtevy zones. Mean weights were calculated for each zone and compared to the predicted Broselow and Handtevy weights using measures of bias, precision, and accuracy. A sub-sample was examined that excluded cases with body mass index (BMI)≥95th percentile. Weights of children longer than each tape also were examined. A total of 3,018 cases from the NHANES database met criteria. Although both tapes underestimated children's weight, the Broselow tape outperformed the Handtevy tape across most length ranges in measures of bias, precision, and accuracy of predicted weights relative to actual weights. Accuracy was higher in the Broselow tape for shorter children and in the Handtevy tape for taller children. Among the sub-sample with cases of BMI≥95th percentile removed, performance of the Handtevy tape improved, yet the Broselow tape still performed better. When assessing the weights of children who were longer than either tape, the actual mean weights did not approximate adult weights; although, those exceeding the Handtevy tape were closer. For pediatric weight estimation, the Broselow tape performed better overall than the Handtevy tape and more closely approximated actual weight. Lowe CG , Campwala RT , Ziv N , Wang VJ .

To estimate organ dose from pediatric chest and abdominopelvic computed tomography (CT) examinations and evaluate the dependency of organ dose coefficients on patient size and CT scanner models. The institutional review board approved this HIPAA-compliant study and did not require informed patient consent. A validated Monte Carlo program was used to perform simulations in 42 pediatric patient models (age range, 0-16 years; weight range, 2-80 kg; 24 boys, 18 girls). Multidetector CT scanners were modeled on those from two commercial manufacturers (LightSpeed VCT, GE Healthcare, Waukesha, Wis; SOMATOM Definition Flash, Siemens Healthcare, Forchheim, Germany). Organ doses were estimated for each patient model for routine chest and abdominopelvic examinations and were normalized by volume CT dose index (CTDI(vol)). The relationships between CTDI(vol)-normalized organ dose coefficients and average patient diameters were evaluated across scanner models. For organs within the image coverage, CTDI(vol)-normalized organ dose coefficients largely showed a strong exponential relationship with the average patient diameter (R(2) > 0.9). The average percentage differences between the two scanner models were generally within 10%. For distributed organs and organs on the periphery of or outside the image coverage, the differences were generally larger (average, 3%-32%) mainly because of the effect of overranging. It is feasible to estimate patient-specific organ dose for a given examination with the knowledge of patient size and the CTDI(vol). These CTDI(vol)-normalized organ dose coefficients enable one to readily estimate patient-specific organ dose for pediatric patients in clinical settings. This dose information, and, as appropriate, attendant risk estimations, can provide more substantive information for the individual patient for both clinical and research applications and can yield more expansive information on dose profiles across patient populations within a practice. © RSNA, 2013.

Diffuse intrinsic pontine gliomas (DIPG) constitute 10-15% of all brain tumors in the pediatric population; currently prognosis remains poor, with an overall survival of 7-14 months. Recently the indication of DIPG biopsy has been enlarged due to the development of molecular biology and various ongoing clinical and therapeutic trials. Classically a biopsy is performed using a stereotactic frame assisted procedure but the workflow may sometimes be heavy and more complex especially in children. In this study the authors present their experience with frameless robotic-guided biopsy of DIPG in a pediatric population. Retrospective study on a series of five consecutive pediatric patients harboring DIPG treated over a 4-year period. All patients underwent frameless robotic-guided biopsy via a transcerebellar approach. Among the 5 patients studied 3 were male and 2 female with a median age of 8.6 years [range 5 to 13 years]. Clinical presentation included ataxia, hemiparesis and cranial nerve palsy in all patients. MRI imaging of the lesion showed typical DIPG features (3 of them located in the pons) with hypo-intensity on T1 and hyper-intensity signal on T2 sequences and diffuse gadolinium enhancement. The mean procedure time was 56minutes (range 45 to 67minutes). No new postoperative neurological deficits were recorded. Histological diagnosis was achieved in all cases as follows: two anaplastic astrocytomas (grade III), two glioblastomas, and one diffuse astrocytoma (grade III). Frameless robotic assisted biopsy of DIPG in pediatric population is an easier, effective, safe and highly accurate method to achieve diagnosis. Copyright © 2016 Elsevier Masson SAS.

The Biopharmaceutics Classification System (BCS) allows compounds to be classified based on their in vitro solubility and intestinal permeability. The BCS has found widespread use in the pharmaceutical community as an enabling guide for the rational selection of compounds, formulation for clinical advancement and generic biowaivers. The Pediatric Biopharmaceutics Classification System (PBCS) working group was convened to consider the possibility of developing an analogous pediatric based classification system. Since there are distinct developmental differences that can alter intestinal contents, volumes, permeability and potentially biorelevant solubilities at the different ages, the PBCS working group focused on identifying age specific issues that would need to be considered in establishing a flexible, yet rigorous PBCS. Objective To summarize the findings of the PBCS working group and provide insights into considerations required for the development of a pediatric based biopharmaceutics classification system. Methods Through several meetings conducted both at The Eunice Kennedy Shriver National Institute of Child Health, Human Development (NICHD)-US Pediatric Formulation Initiative (PFI) workshop (November 2011) and via teleconferences, the PBCS working group considered several high level questions that were raised to frame the classification system. In addition, the PBCS working group identified a number of knowledge gaps that would need to be addressed in order to develop a rigorous PBCS. Results It was determined that for a PBCS to be truly meaningful, it would need to be broken down into several different age groups that would account for developmental changes in intestinal permeability, luminal contents, and gastrointestinal transit. Several critical knowledge gaps where identified including: 1) a lack of fully understanding the ontogeny of drug metabolizing enzymes and transporters along the gastrointestinal (GI) tract, in the liver and in the kidney; 2) an incomplete understanding of age-based changes in the GI, liver and kidney physiology; 3) a clear need to better understand age-based intestinal permeability and fraction absorbed required to develop the PBCS; 4) a clear need for the development and organization of pediatric tissue biobanks to serve as a source for ontogenic research; and 5) a lack of literature published in age-based pediatric pharmacokinetics in order to build Physiologically- and Population-Based Pharmacokinetic (PBPK) databases. Conclusions To begin the process of establishing a PBPK model, ten pediatric therapeutic agents were selected (based on their adult BCS classifications). Those agents should be targeted for additional research in the future. The PBCS working group also identified several areas where a greater emphasis on research is needed to enable the development of a PBCS. PMID:23149009

Unintentional burn injury is the third most common cause of death in the U.S. for children age 5 to 9, and accounts for major morbidity in the pediatric population. Pediatric burn admission data from U.S. institutions has not been reported recently. This study assesses all pediatric burn admissions to a State wide Certified Burn Treatment Center to evaluate trends in demographics, burn incidence, and cause across different age groups. Demographic and clinical data were collected on 2273 pediatric burn patients during an 18-year period (1995-2013). Pediatric patients were stratified by age into "age 0 to 6," "age 7 to 12," and "age 13 to 18." Data were obtained from National Trauma Registry of the American College of Surgeons and analyzed using standard statistical methodology. A total of 2273 burn patients under age 18 were treated between 1995 and 2013. A total of 1663 (73.2%) patients were ages 0 to 6, 294 (12.9%) were 7 to 12, and 316 (13.9%) were age 13 to 18. A total of 1400 (61.6%) were male and 873 (38.4%) were female (male:female ratio of 1.6:1). Caucasians had the highest burn incidence across all age groups (40.9%), followed by African-Americans (33.6%), P < .001. Caucasian teenagers formed 62.1% of patients age 13-18, P < .001. A total of 66.3% of all pediatric burns occurred at home, P < .001. Mean TBSA burned was 8.9%, with lower extremity being the most common site (38.5%). Scald burns constituted the majority of cases (71.1%, n = 1617), with 53% attributable to hot liquids related to cooking, including coffee or tea, P < .001. In the teenage group, flame burns were the dominant cause (53.8%). Overall mean length of stay was 10.5 ± 10.8 days for all patients, and15.5 ± 12 for those admitted to the intensive care unit, P < .005. One hundred (4.4%) patients required ventilator support (P = .02), and average duration of mechanical ventilation was 11.9 ± 14.5 days. Skin grafting was performed for 520 (22.9%) patients, P < .001. Overall mortality was 0.9% (n = 20), with mean TBSA involved of 61.5%. The majority of pediatric burn injuries are scald burns that occur at home and primarily affect the lower extremities in Caucasian and African-American males. Among Caucasian teenagers flame burns predominate. Mean length of stay was 10 days, 23% of patients required skin grafting surgery, and mortality was 0.9%. The results of this study highlight the need for primary prevention programs focusing on avoiding home scald injuries in the very young, as well as fire safety training for teenagers.

Road traffic incidents (RTIs), falls, and violence contribute to more than two thirds of pediatric traumatic brain injuries in sub-Saharan Africa. In this study, we sought to assess mechanisms of pediatric traumatic brain injury in an effort to propose interventions for more effective pediatric head injury prevention. A cohort of 100 patients who were <18 years treated at Mbarara Regional Referral Hospital between November 2016 and June 2017 were enrolled in the study. Information on etiology of injury was obtained via a questionnaire administered to patient caretakers at the time of admission. The mean age was found to be 7.5 years (standard deviation 5.2) and 38% were female. In our sample, 61% had computed tomography imaging done, of whom 88.5% had a positive finding. A majority of patients presented with a mild head injury (55%). RTIs were the predominant mechanism of injury across age groups (75%). Across all age groups, falls were responsible for a greater proportion of injuries in children aged 10-14 years (13.3%), whereas the greatest proportion of intentional injuries was reported in age group 10-14 and 15-17 years, 20% and 31.3%, respectively. Patients involved in pedestrian RTIs were significantly younger compared with those injured in nonpedestrian RTIs. Most parents (87.9%) were not with their children at the time of a pedestrian RTI. In Southwestern Uganda, the majority of pediatric neurotrauma patients are injured pedestrians, with no adult supervision at the time of the injury. Conducting a public awareness and education campaign on the necessity of child supervision is critical to decreasing pediatric head injuries in Uganda. Copyright © 2018 Elsevier Inc.

2017-01-01

Background: Incidence of dog bites continues to rise among the pediatric population and serves as a public health threat for the well-being of children. Plastic surgeons are at the forefront of initial management and eventual outcome of these devastating injuries. This study set out to determine the nature of dog bite injuries treated over a 3-year period at a large level 1 pediatric trauma center. Methods: A retrospective review of emergency room records of all pediatric patients (age, 0–18 years old) who sustained dog bites between January 2012 and December 2014 were gathered. All details about age of patient, location and severity of dog bites, type of dog breed, antibiotics given, and emergency versus operative treatment were recorded and analyzed. Results: One hundred eight patients aged 5 months to 18 years old were treated in the emergency department after suffering dog bite injuries during the study period. The highest incidence of dog bites occurred in preschool children. The mean age for patients who required operative repair was lower than the mean age for patients who underwent primary closure in the emergency department. The location of injury was most commonly isolated to the head/neck region. Of the 56 cases that had an identified dog breed, pit bulls accounted for 48.2% of the dog bites, and 47.8% of pit bull bites required intervention in the operating room. Conclusion: Children with large dog bite injuries require more immediate care in a level 1 pediatric trauma hospitals in order to optimize their hospitalization course and eventual outcome.

The aim of the study was to investigate the psychometric properties of the Hungarian version of the Pediatric Quality of Life Inventory (PedsQL) Generic Core Scales and Cardiac Module. The PedsQL 4.0 Generic Core Scales and the PedsQL 3.0 Cardiac Module was administered to 254 caregivers of children (aged 2-18 years) and to 195 children (aged 5-18 years) at a pediatric cardiology outpatient unit. A postal survey on a demographically group-matched sample of the general population with 525 caregivers of children (aged 2-18 years) and 373 children (aged 5-18 years) was conducted with the PedsQL 4.0 Generic Core Scale. Responses were described, compared over subgroups of subjects, and were used to assess practical utility, distributional coverage, construct validity, internal consistency, and inter-reporter agreement of the instrument. The moderate scale-level mean percentage of missing item responses (range 1.8-2.3%) supported the feasibility of the Generic Core Scales for general Hungarian children. Minimal to moderate ceiling effects and no floor effects were found on the Generic Core Scales. We observed stronger ceiling than floor effects in the Cardiac Module. Most of the scales showed satisfactory reliability with Cronbach's alpha estimates exceeding 0.70. Generally, moderate to good agreement was found between self- and parent proxy-reports in the patient and in the comparison group (intraclass correlation coefficient range 0.52-0.77), but remarkably low agreement in the perceived physical appearance subscale in the age group 5-7 years (0.18) and for the treatment II scale (problems on taking heart medicine) scale of the Cardiac Module in children aged 8-12 years (0.39). Assessing the construct validity of the questionnaires, statistically significant difference was found between the patient group and the comparison group only in the Physical Functioning Scale scores (p = 0.003) of the child self-report component, and in Physical (p = 0.022), Emotional, (p = 0.017), Psychosocial Summary (p = 0.019) scores and in the total HRQoL (health-related quality of life) scale score (p = 0.034) for parent proxy-report. The findings generally support the feasibility, reliability and validity of the Hungarian translation of the PedsQL 4.0 Generic Core Scales and the PedsQL 3.0 Cardiac Module in Hungarian children with heart disease.

Graft survival rates from deceased donors aged 35 years or less among all primary pediatric kidney transplant recipients in the United States between 1996 and 2004 were retrospectively examined to determine the effect of HLA-DR mismatches on graft survival. Zero HLA-DR-mismatched kidneys had statistically comparable 5-year graft survival (71%), to 1-DR-mismatched kidneys (69%) and 2-DR-mismatched kidneys (71%). When compared to donors less than 35 years of age, the relative rate of allograft failure was 1.32 (p = 0.0326) for donor age greater than or equal to age 35. There was no statistical increase in the odds of developing a panel-reactive antibody (PRA) greater than 30% at the time of second waitlisting, based upon the degree of HLA-A, -B or -DR mismatch of the first transplant, nor was there a 'dose effect' when more HLA antigens were mismatched between the donor and recipient. Therefore, pediatric transplant programs should utilize the recently implemented Organ Procurement and Transplantation Network's (OPTN)allocation policy, which prioritizes pediatric recipients to receive kidneys from deceased donors less than 35 years of age, and should not turn down such kidney offers to wait for a better HLA-DR-matched kidney.

The purpose of this study was to describe the role of public exercise equipment in pediatric hand traumas as a preventable etiological factor. Pediatric patients with hand injuries referred from the emergency department were evaluated retrospectively. Age and gender of the patients, timing, etiology, mechanism of hand trauma, localization of the injury, diagnoses of the patients, and hospitalization rates were reviewed. Amongst the 310 pediatric patients evaluated, 31 patients (10%) experienced injury related to public exercise equipment. Within this group of patients, most were between 5 to 9 years of age, and all injuries were blunt and crush type. Lacerations and fractures were the main diagnoses. Complex injuries that required inpatient care were reported in 19.3% of the patients. Public exercise equipment-related injuries are increasingly prevalent in pediatric hand traumas. Preventive actions such as shielding the moving parts should be taken to reduce these rates.

The aim of this study was to evaluate the treatment outcomes of intravitreal bevacizumab (IVB) injections, used as a monotherapy in type 1 retinopathy of prematurity (ROP). A retrospective chart review was performed for 17 type 1 ROP patients (34 eyes), who had IVB injection between July 2011 and June 2012. Birthweight, gestational age at birth, stage and location of ROP, IVB injection time, time of complete retinal vascularization, and additional treatments if needed, were noted. A total of 0.625 mg (0.025 mL) bevacizumab was injected intravitreally. Thirty eyes of 17 patients with type 1 ROP enrolled in the study were treated with IVB injection. Of them seven had aggressive posterior-ROP, six had stage 2 ROP, and four had stage 3 ROP. The mean gestational age was 28.44 weeks (range, 26-31 weeks); and the mean birthweight was 1151.88 g (range, 600-1600 g). The mean age for IVB injection was 35.47 weeks. The mean full retinal vascularization time was 136.6 ± 26.6 days. The mean follow-up time was 285.3 ± 70 days. ROP was regressed and retinal vascularization was completed in all cases except one eye, which had threshold disease. IVB injection, used as a monotherapy, is an effective treatment approach in patients with type 1 ROP. Timely treatment of stage 2 and early stage 3 ROP in which disease progression was observed, prevents vitreoretinal membrane formation in posterior disease. Further studies need to be performed to determine the safety of IVB injection. © 2013 The Authors. Pediatrics International © 2013 Japan Pediatric Society.

Biomechanical tensile testing of perinatal, neonatal, and pediatric cadaveric cervical spines to failure. To assess the tensile failure properties of the cervical spine from birth to adulthood. Pediatric cervical spine biomechanical studies have been few due to the limited availability of pediatric cadavers. Therefore, scaled data based on human adult and juvenile animal studies have been used to augment the limited pediatric cadaver data. Despite these efforts, substantial uncertainty remains in our understanding of pediatric cervical spine biomechanics. A total of 24 cadaveric osteoligamentous head-neck complexes, 20 weeks gestation to 18 years, were sectioned into segments (occiput-C2 [O-C2], C4-C5, and C6-C7) and tested in tension to determine axial stiffness, displacement at failure, and load-to-failure. Tensile stiffness-to-failure (N/mm) increased by age (O-C2: 23-fold, neonate: 22 ± 7, 18 yr: 504; C4-C5: 7-fold, neonate: 71 ± 14, 18 yr: 509; C6-C7: 7-fold, neonate: 64 ± 17, 18 yr: 456). Load-to-failure (N) increased by age (O-C2: 13-fold, neonate: 228 ± 40, 18 yr: 2888; C4-C5: 9-fold, neonate: 207 ± 63, 18 yr: 1831; C6-C7: 10-fold, neonate: 174 ± 41, 18 yr: 1720). Normalized displacement at failure (mm/mm) decreased by age (O-C2: 6-fold, neonate: 0.34 ± 0.076, 18 yr: 0.059; C4-C5: 3-fold, neonate: 0.092 ± 0.015, 18 yr: 0.035; C6-C7: 2-fold, neonate: 0.088 ± 0.019, 18 yr: 0.037). Cervical spine tensile stiffness-to-failure and load-to-failure increased nonlinearly, whereas normalized displacement at failure decreased nonlinearly, from birth to adulthood. Pronounced ligamentous laxity observed at younger ages in the O-C2 segment quantitatively supports the prevalence of spinal cord injury without radiographic abnormality in the pediatric population. This study provides important and previously unavailable data for validating pediatric cervical spine models, for evaluating current scaling techniques and animal surrogate models, and for the development of more biofidelic pediatric crash test dummies.

The relationship between the testis and tunica vaginalis changes with age.

Anatomy of the testis and tunica vaginalis (TV) is taught to pediatric surgeons from adult postmortem material. Textbooks describe the testis as 'behind' the TV, but at pediatric orchidopexy it appears to be inside the TV. We aimed to study whether testis and TV anatomy changes with age. After ethical approval, postmortem photographs and measurements of testis length, width, and mesenteric attachment length (mm) in 37 adults (22-92years), one infant (4/12), and one fetus (19/52) were compared with intraoperative orchidopexies (x6) after opening TV (n=4; 7/12-14years). Testis length, area and perimeter and ratios for mesentery attachment were plotted against age. The fetal and pediatric testes were intraperitoneal with a mesentery (mesorchium), but after 50years secondary adhesions between TV and testis obliterated the mesorchium, so in advanced age the testis appeared to be behind the TV. These results show that in childhood testes were 'intraperitoneal', but after 50years of age the TV progressively shrinks and adheres to the testis, making it appear to be behind the TV. This difference between anatomical texts and childhood anatomy suggests that pediatric surgery may need anatomy texts that specifically highlight age differences. Copyright © 2015 Elsevier Inc.

To assess if magnetic resonance enterography is capable of showing evidence/extent of disease in pediatric patients with biopsy-proven celiac disease by comparing with a control group, and to correlate the magnetic resonance enterography findings with anti-endomysial antibody level, which is an indicator of gluten-free dietary compliance. Thirty-one pediatric patients (mean age 11.7±3.1 years) with biopsy-proven celiac disease and 40 pediatric patients as a control group were recruited in the study. The magnetic resonance enterography images of both patients with celiac disease and those of the control group were evaluated by two pediatric radiologists in a blinded manner for the mucosal pattern, presence of wall thickening, luminal distention of the small bowel, and extra-intestinal findings. Patient charts were reviewed to note clinical features and laboratory findings. The histopathologic review of the duodenal biopsies was re-conducted. The mean duration of the disease was 5.6±1.8 years (range: 3-7.2 years). In 24 (77%) of the patients, anti-endomysial antibody levels were elevated (mean 119.2±66.6RU/mL). Magnetic resonance enterography revealed normal fold pattern in all the patients. Ten (32%) patients had enlarged mesenteric lymph nodes. Although a majority of the patients had elevated anti-endomysial antibody levels indicating poor dietary compliance, magnetic resonance enterography did not show any mucosal abnormality associated with the inability of magnetic resonance enterography to detect mild/early changes of celiac disease in children. Therefore, it may not be useful for the follow-up of pediatric celiac disease. Copyright © 2017 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda. All rights reserved.

Paradoxical vocal fold motion (PVFM) in pediatric otolaryngology.

PubMed

Smith, Blake; Milstein, Claudio; Rolfes, Bryan; Anne, Samantha

Paradoxical vocal fold motion (PVFM) is a condition in which the vocal cords exhibit inappropriate inspiratory adduction, and it has been poorly studied in the pediatric population. Pediatric patients diagnosed with PVCM by a pediatric otolaryngologist and doctor of speech pathology from 2008 to 2012 were reviewed. Patients in whom another cause for their respiratory disturbance was eventually identified were excluded. Patient demographics, characteristics, treatment, and outcomes were reviewed. The study was approved by the Institutional Review Board at our institution. Thirty patients met criteria for inclusion; one with chiari malformation was excluded. 17/29 (59%) were female. Body mass index (BMI) numbers ranged from 16 to 25 with a mean of 21. 9/29 (31%) competed at the highest level of a sport; only 3/29 (10%) did not participate in athletics. Average age of onset was 12.0years; average diagnosis delay was 1.3years. Mean follow up was 2.3years. 24/29 (83%) were previously treated for asthma. 23/29(79%) were previously treated for reflux. 25/29(86%) completed at least one session of respiratory and laryngeal control therapy with overall average of 2.2 sessions completed. All patients who attended a second therapy session were recorded as having improvement in symptoms. Pediatric patients with PVFM often participate in high levels of organized sports and the frequency of concurrent asthma and reflux symptoms in this population supports the theory that laryngeal hypersensitivity contributes to the pathophysiology of PVFM. These patients were not found to have any associated psychiatric diagnoses. Pediatric patients with PVFM have an excellent prognosis when treated with speech therapy and for comorbid conditions as indicated. Copyright © 2017 Elsevier Inc. All rights reserved.

The dearth of age-appropriate formulations of many medicines for children poses a major challenge to pediatric therapeutic practice, adherence, and health care delivery worldwide. We provide information on current administration practices of pediatric medicines and describe key stakeholder preferences for new formulation characteristics. We surveyed children aged 6-12 years, parents/caregivers over age 18 with children under age 12, and healthcare workers in 10 regions of Tanzania to determine current pediatric medicine prescription and administration practices as well as preferences for new formulations. Analyses were stratified by setting, pediatric age group, parent/caregiver education, and healthcare worker cadre. Complete data were available for 206 children, 202 parents/caregivers, and 202 healthcare workers. Swallowing oral solid dosage forms whole or crushing/dissolving them and mixing with water were the two most frequently reported methods of administration. Children frequently reported disliking medication taste, and many had vomited doses. Healthcare workers reported medicine availability most significantly influences prescribing practices. Most parents/caregivers and children prefer sweet-tasting medicine. Parents/caregivers and healthcare workers prefer oral liquid dosage forms for young children, and had similar thresholds for the maximum number of oral solid dosage forms children at different ages can take. There are many impediments to acceptable and accurate administration of medicines to children. Current practices are associated with poor tolerability and the potential for under- or over-dosing. Children, parents/caregivers, and healthcare workers in Tanzania have clear preferences for tastes and formulations, which should inform the development, manufacturing, and marketing of pediatric medications for resource-limited settings.

Biotin deficiency has been reported in Japanese infants fed special formulas for medical reasons, including those with milk allergy and congenital metabolic diseases, because these formulas contain little biotin. Serum biotin measurement is useful for diagnosing biotin deficiency. We applied a simple and rapid method to analyze serum biotin, and established normal ranges for children and adults. Serum biotin in 188 healthy Japanese children aged 0-4 years and in 25 healthy adults was analyzed using a Biotin ELISA Kit (immundiagnostik). The effects of various conditions on the measurement of serum biotin were also examined. Median biotin in children aged 0-4 years was 10.4 ng/dL (IQR, 7.9-13.4 ng/dL), and that in adults was 12.9 ng/dL (IQR, 10.8-15.8 ng/dL). Normal range was 4.7-22.0 ng/dL in children and 8.4-20.5 ng/dL in adults (calculated using two-sided 95%CI). Measurements obtained with this method were not affected by frozen storage, freeze-thaw, or hemolysis, indicating that serum biotin can be analyzed accurately under these conditions, with a possible application to plasma samples. Serum biotin was significantly lower in children than in adults, with the normal range being 4.7-22.0 ng/dL in children and 8.4-20.5 ng/dL in adults. This simple and accurate enzyme-linked immunosorbent assay method is useful for diagnosing biotin deficiency. © 2016 The Authors.

2001-01-01

We studied six pediatric amputees with long below-knee residual limbs, in order to delineate their functional and prosthetic situations, specifically in relation to problems with fitting for dynamic-response prosthetic feet. Three patients had congenital pseudoarthrosis of the tibia secondary to neurofibromatosis, one had fibular hemimelia, one had a traumatic amputation, and one had amputation secondary to burns. Five patients had Syme's amputations, one had a Boyd amputation. Ages at amputation ranged from nine months to five years (average age 3 years 1 month). After amputation, the long residual below-knee limbs allowed fitting with only the lowest-profile prostheses, such as deflection plates. In three patients, the femoral dome to tibial plafond length was greater on the amputated side than on the normal side. To allow room for more dynamic-response (and larger) foot prostheses, two patients have undergone proximal and distal tibial-fibular epiphyseodeses (one at age 5 years 10 months, the other at 3 years 7 months) and one had a proximal tibial-fibular epiphyseodesis at age 7 years 10 months. (All three patients are still skeletally immature.) The families of two other patients are considering epiphyseodeses, and one patient is not a candidate (skeletally mature). Scanogram data indicate that at skeletal maturity the epiphyseodesed patients will have adequate length distal to their residual limbs to fit larger and more dynamic-response prosthetic feet.

Few studies have reported prescription patterns for headache medication. The aim was to present the rates of specific medication prescribed to pediatric patients diagnosed with migraine, tension-type headache (TTH), and new daily persistent headache (NDPH), as well as differences in those prescription patterns by diagnosis, age, and gender. A query using the i2b2 platform yielded 14,591 patients [migraine 10,547 (72.3%); TTH 3200 (21.9%); NDPH 844 (5.8%)] seen over a 3-year period, who were aged 4-17 years at the time of their visit and diagnosed with migraine, TTH, or NDPH. Sumatriptan was the most frequently prescribed medication for migraine followed by amitriptyline. The most frequently prescribed medication for both TTH and NDPH was amitriptyline, followed by sumatriptan in TTH and by topiramate in NDPH. Age and gender differences were also found in prescription patterns of each of the diagnoses. The differences in prescription patterns found between the diagnoses, as well as age and gender differences found within the diagnoses, are discussed. A wide range of medications are prescribed to children and adolescents with headache, with most medications prescribed for off-label use. As these medications are not Food and Drug Administration (FDA) approved for use in children and adolescents with headache, there is a need for large scale, randomized controlled trials to assess the efficacy of these medications.

The aim of the study was to find out whether or not there is consensus among experienced pediatric orthopaedists about the management of certain clinical scenarios in Legg-Calvé-Perthes' disease. A questionnaire was sent to all 297 members of the European Paediatric Orthopaedic Society (EPOS) describing four cases of Legg-Calvé-Perthes' disease (LCPD) with two X-rays each and a short description of the clinical scenario. Two of the patients were younger and two were older than six years of age. From both age groups there was one with a good range of motion and an X-ray classified as Herring A or B, while the other patient had a poor range of motion and an X-ray classified as Herring C. EPO members were asked to choose from various treatment options or to describe any other therapy that they would advise in the clinical scenarios. One-hundred and fifty members answered the questionnaire. The participants had an average of 20 years of experience in pediatric orthopaedics. There was a consensus that no surgery should be performed in a young patient with a good range of motion and that there should be no weight relief when older with a good range of motion. Conservative containment treatment (abduction splint, Petrie cast) and arthrodiastasis was suggested in only very few centres. There was a tendency to perform an operation when the patient is older with a poor range of motion and to perform operative treatment only when there were subluxation or head at risk signs. pelvic osteotomies or a combination of pelvic and femoral osteotomies rather than femoral osteotomies alone. Age did not determine the indication for treatment and there was no agreement on the indications for physiotherapy. There was also no consensus on the type of pelvic osteotomy to be used. The study showed that indications for the treatment of LCPD is based more on the personal experience of the surgeon rather than on scientific data.

Pediatric patient-reported outcome instruments for research to support medical product labeling: report of the ISPOR PRO good research practices for the assessment of children and adolescents task force.

Patient-reported outcome (PRO) instruments for children and adolescents are often included in clinical trials with the intention of collecting data to support claims in a medical product label. The purpose of the current task force report is to recommend good practices for pediatric PRO research that is conducted to inform regulatory decision making and support claims made in medical product labeling. The recommendations are based on the consensus of an interdisciplinary group of researchers who were assembled for a task force associated with the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). In those areas in which supporting evidence is limited or in which general principles may not apply to every situation, this task force report identifies factors to consider when making decisions about the design and use of pediatric PRO instruments, while highlighting issues that require further research. Five good research practices are discussed: 1) Consider developmental differences and determine age-based criteria for PRO administration: Four age groups are discussed on the basis of previous research (<5 years old, 5-7 years, 8-11 years, and 12-18 years). These age groups are recommended as a starting point when making decisions, but they will not fit all PRO instruments or the developmental stage of every child. Specific age ranges should be determined individually for each population and PRO instrument. 2) Establish content validity of pediatric PRO instruments: This section discusses the advantages of using children as content experts, as well as strategies for concept elicitation and cognitive interviews with children. 3) Determine whether an informant-reported outcome instrument is necessary: The distinction between two types of informant-reported measures (proxy vs. observational) is discussed, and recommendations are provided. 4) Ensure that the instrument is designed and formatted appropriately for the target age group. Factors to consider include health-related vocabulary, reading level, response scales, recall period, length of instrument, pictorial representations, formatting details, administration approaches, and electronic data collection (ePRO). 5) Consider cross-cultural issues. Additional research is needed to provide methodological guidance for future studies, especially for studies involving young children and parents' observational reports. As PRO data are increasingly used to support pediatric labeling claims, there will be more information regarding the standards by which these instruments will be judged. The use of PRO instruments in clinical trials and regulatory submissions will help ensure that children's experience of disease and treatment are accurately represented and considered in regulatory decisions.

Purpose: With increased focus on radiation dose from medical imaging, prospective radiation dose estimates are becoming increasingly desired. Using available populations of adult and pediatric patient phantoms, radiation dose calculations can be catalogued and prospectively applied to individual patients that best match certain anatomical characteristics. In doing so, the knowledge of organ size and location is a required element. Here, the authors develop a predictive model of organ locations and volumes based on an analysis of adult and pediatric computed tomography (CT) data. Methods: Fifty eight adult and 69 pediatric CT datasets were segmented and utilized in the study. Themore » maximum and minimum points of the organs were recorded with respect to the axial distance from the tip of the sacrum. The axial width, midpoint, and volume of each organ were calculated. Linear correlations between these three organ parameters and patient age, BMI, weight, and height were determined. Results: No statistically significant correlations were found in adult patients between the axial width, midpoint, and volume of the organs versus the patient age or BMI. Slight, positive linear trends were found for organ midpoint versus patient weight (max r{sup 2} = 0.382, mean r{sup 2} = 0.236). Similar trends were found for organ midpoint versus height (max r{sup 2} = 0.439, mean r{sup 2} = 0.200) and for organ volume versus height (max r{sup 2} = 0.410, mean r{sup 2} = 0.153). Gaussian fits performed on probability density functions of the adult organs resulted in r{sup 2}-values ranging from 0.96 to 0.996. The pediatric patients showed much stronger correlations overall. Strong correlations were observed between organ axial midpoint versus age, height, and weight (max r{sup 2} = 0.842, mean r{sup 2} = 0.790; max r{sup 2} = 0.949, mean r{sup 2} = 0.894; and max r{sup 2} = 0.870, mean r{sup 2} = 0.847, respectively). Moderate linear correlations were also observed for organ axial width versus height (max r{sup 2} = 0.772, mean r{sup 2} = 0.562) and for organ volume versus height (max r{sup 2} = 0.781, mean r{sup 2} = 0.601). Conclusions: Adult patients exhibited small variations in organ volume and location with respect to height and weight, but no meaningful correlation existed between these parameters and age or BMI. Once adulthood is reached, organ morphology and positioning seem to remain static. However, clear trends are evident between pediatric organ locations versus age, height, and weight. Such information can be incorporated into a matching methodology that may provide the highest probability of representing the anatomy of a patient undergoing a clinical exam to prospectively estimate the radiation dose.« less

Upper pole access is safe and effective for pediatric percutaneous nephrolithotomy.

Upper pole access in percutaneous nephrolithotomy (PCNL) provides a straight tract to the ureter, resulting in easier placement of a guidewire to the ureter, good exposure of the pelvis, calices, and upper ureter, and comfortable manipulations. However, despite these benefits, upper pole access is usually avoided because of the risk of chest complications in both pediatric and adult patients. We aimed to evaluate the safety and morbidity of single upper pole access in pediatric patients undergoing PCNL. We retrospectively reviewed patients aged ≤17 years with renal stones who underwent PCNL with a single access between August 2004 and February 2016. The patients were separated into two groups: the single upper pole access group (SUPAG) and the single other pole access group (SOPAG). We compared the SUPAG and SOPAG in terms of the demographic features of the patients, stone burden and location, operative data, and postoperative outcomes. Complications were classified according to the modified Clavien system. During the study period, 101 PCNL procedures were performed, 77 of which were managed with only one access. The median age of the 77 patients managed with a single access was 12 years (range 3-17 years). The number of cases in the SUPAG and SOPAG was 10 and 67, respectively. There were no statistically significant differences between the SUPAG and SOPAG in terms of age, sex, stone location, hydronephrosis status, stone area, side of kidney, and previous stone treatment or renal surgery. Furthermoret, there were no significant differences between the groups in terms of the operative parameters. Although the difference was insignificant, the median operation times in the SUPAG and SOPAG were 37 and 45 min, respectively. There was no chest complication or bleeding that required transfusion in the SUPAG. Two cases required transfusion, and one case was managed with a double pigtail catheter (double-J) placement because of prolonged extravasation in the SOPAG. The stone-free ratios were 100% and 82.1% in the SUPAG and SOPAG, respectively. Upper pole access provides similar outcomes to other (middle and lower) pole accesses, and may be performed without serious complications. These results indicate that this is a safe and effective approach of PCNL, and it presents a good alternative for removal of renal stones in pediatric patients.

To assess the differences in work needed for pediatric and adult ophthalmologic examinations. Seven ophthalmology residents conducted slit-lamp and refraction examinations on children 3-7 years of age and adults 20-69 years of age. The examiners reported the magnitude estimate (ME) of their work in relation to two references (cross-reference ME): average adult examination and average pediatric examination. The examination time was also measured. For the slit-lamp examination, 50 children and 58 adults were recruited. The ME was 1.45 (95% CI, 1.30-1.62) times higher for the pediatric examinations than for the adult examinations when the reference was an average adult case. With respect to time, the pediatric examinations took 1.22 (95% CI, 1.06-1.41) times longer than the adult examinations. For the refraction examinations, 58 children and 96 adults were recruited. The ME was 1.35 (95% CI, 1.21-1.52) times higher for the pediatric examinations. The pediatric examination took 1.32 (95% CI, 1.16-1.50) times longer than the adult examination. The cross-reference ME ratios measuring the pediatric over adult examinations against both the pediatric and adult reference cases were equivalent in both the slit-lamp and the refraction examinations; however, the ME and time ratios of the pediatric over the adult examinations were not equivalent for the slit-lamp or for the refraction examinations. The cross-reference ME showed that pediatric ophthalmologic examinations require more work than the adult examination with validity and reliability. The time estimate was insufficient as a single indicator for work estimation. Copyright © 2017 American Association for Pediatric Ophthalmology and Strabismus. Published by Elsevier Inc.

The term cystic nephroma has traditionally been used to refer to 2 neoplasms, a lesion in adults that is now thought to be part of the spectrum of mixed epithelial stromal tumor (MEST) and a pediatric lesion that has been associated with mutations in the DICER1 gene. A direct detailed morphologic, immunohistochemical, and genetic comparison of these 2 lesions has not been performed. In this study, we compare the morphologic features, immunoreactivity for estrogen receptor and inhibin, and DICER1 genetic status of 12 adult cystic nephroma/MEST (median age 50.5 y, all females) and 7 pediatric cystic nephroma (median age 1.3 y, male:female=6:1). Both lesions (11 of 12 adult cases, 6 of 7 pediatric cases) frequently demonstrated subepithelial accentuation of stromal cellularity, though the increased cellularity frequently included inflammatory cells in the pediatric cases. All adult and pediatric cases labeled for estrogen receptor; however, whereas most (83%) of adult cases labeled for inhibin at least focally, no pediatric case labeled for inhibin. Most adult cases (58%) demonstrated wavy, ropy collagen in association with cellular stroma, whereas this was not found in pediatric cases. 86% of pediatric cases demonstrated DICER1 mutations, whereas only 1 of 10 adult cases demonstrated a DICER1 mutation. In summary, although cellular stroma and estrogen receptor immunoreactivity are commonly present in both adult and pediatric cystic nephroma, ropy collagen and inhibin immunoreactivity are far more common in adult cystic nephroma/MEST, whereas DICER1 mutations are far more prevalent in pediatric cystic nephroma. These results support the current World Health Organization Classification's separation of adult and pediatric cystic nephromas as distinct entities.

ABSTRACT Objetive: to characterize the care services performed through risk rating by the Manchester Triage System, identifying demographics (age, gender), main flowcharts, discriminators and outcomes in pediatric emergency Method: cross-sectional quantitative study. Data on risk classification were obtained through a search of computerized registration data from medical records of patients treated in the pediatric emergency within one year. Descriptive statistics with absolute and relative frequencies was used for the analysis. Results: 10,921 visits were conducted in the pediatric emergency, mostly male (54.4%), aged between 29 days and two years (44.5%). There was a prevalence of the urgent risk category (43.6%). The main flowchart used in the care was worried parents (22.4%) and the most prevalent discriminator was recent event (15.3%). The hospitalization outcome occurred in 10.4% of care performed in the pediatric emergency, however 61.8% of care needed to stay under observation and / or being under the health team care in the pediatric emergency. Conclusion: worried parents was the main flowchart used and recent events the most prevalent discriminator, comprising the hospitalization outcomes and permanency in observation in the pediatric emergency before discharge from the hospital.

Acute lymphoblastic leukemia (ALL) is the most frequent cancer in childhood, with cure rates of 80-85%. In T-cell ALL (15% of ALL), prognostic factors are ill defined. We aimed to describe the event-free survival (EFS) and analyze clinical prognostic factors in a series of pediatric T-ALL of 4 consecutive clinical trials. Children with T-ALL aged 1-18 years treated in 37 institutions in Spain were enrolled in 4 consecutive trials from February-1989 to November-2009. A total of 218 T-ALL patients out of 1,652 pediatric ALL were evaluable during the study period (SHOP/ALL-89: 35, ALL-94: 63, ALL-99: 62, ALL-2005: 58). There were 164 boys (75%). Median age (years) was 7.8 range (1.3-18.6). Median leukocytes (10(9)/L) was 78.2, range 0.8-930. Fifteen (6.8%) children had central nervous system (CNS) involvement at diagnosis. Regarding response to induction treatment, 150 (75%) patients had less than 5% blasts on day-14 bone marrow and 199 achieved complete remission at the end of induction. Overall survival (OS) at 60 months for SHOP/ALL-89, ALL-94, ALL-99 was 48 (8), 49 (6), 70 (6) %, respectively, and at 48 months for SHOP/ALL-2005 (ongoing protocol) was 74 (8) %. Median follow-up (months) was 206, 152, 74 and 17 respectively. Analysis of prognostic factors revealed no statistical differences regarding sex or age. Leukocyte count over 200×10(9)/l (P=.024), CNS infiltration at diagnosis (P<.006) and treatment response had prognostic significance (end-induction complete remission) (P=.0000), day 14-bone marrow (P=.005). Results for the SHOP/ALL-89 and ALL-94 protocols were inferior to other contemporary protocols but there has been an improvement in survival in the 2 last trials. In line with other T-ALL series, response to treatment had the strongest prognostic impact. Copyright © 2011 Elsevier España, S.L. All rights reserved.

Tuberculosis (TB) of the cranio-vertebral junction (CVJ) is a rare condition, accounting for 0.3 % to 1 % of all cases of spinal TB. Early diagnosis and treatment are important in preventing long-term neurological sequelae. Management protocol of this rare site of TB is yet to be conclusively established. This holds particularly true for pediatric age group in which this condition is infrequently encountered. A total of 29 consecutive pediatric patients presented to the Department of Neurosurgery at Sanjay Gandhi Post-Graduate Institute of Medical Sciences, Lucknow, from January 1997 to October2011 with clinical and/or radiological features suggestive of CVJ TB. A clinical grading system to evaluate the neurological status was developed, and all patients were evaluated using this scoring system. Patients were radiologically evaluated with computed tomography (CT) of CVJ and magnetic resonance imaging (MRI) with gadolinium enhancement. These cases were managed according to their grade and followed up. Out of a total of 29 cases, 18 were females and 11 males. Age range was 4 to 18 years with mean age 9 ± 3.8 years. The follow-up period ranged from 2 months to 7.5 years with mean follow-up of 2.7 years. Eleven cases were of grades 1 and 2, and 18 cases were of higher grade (grades 3 and 4). Predominantly conservative approach was utilized in cases with better clinical status, and grade (grades 1 and 2) and surgical intervention was needed in the more severe grades. All cases had significant improvement at the last follow-up. One needs to have a high index of suspicion of CVJ TB if one encounters a case with neck pain, neck restriction, and raised erythrocyte sedimentation rate. CT CVJ and MRI with gadolinium contrast enhancement are the investigations of choice for both establishing a diagnosis and planning the management. For cases with mild neurological deficit, conservative approach would work for majority of cases, and for severe cases, initial conservative approach may be tried, failing which surgical intervention would be needed.

The Pediatric Outcomes Data Collection Instrument (PODCI) was developed in 1994 as a patient-based tool for use across a broad age range and wide array of musculoskeletal disorders, including children with cerebral palsy (CP). The purpose of this study was to establish means and SDs of the Parent PODCI measures by age groups and Gross Motor Function Classification System (GMFCS) levels for ambulatory children with CP. This instrument was one of several studied in a prospective, multicenter project of ambulatory patients with CP between the aged 4 and 18 years and GMFCS levels I through III. Participants included 338 boys and 221 girls at a mean age of 11.1 years, with 370 diplegic, 162 hemiplegic, and 27 quadriplegic. Both baseline and follow-up data sets of the completed Parent PODCI responses were statistically analyzed. Age was identified as a significant predictor of the PODCI measures of Upper Extremity Function, Transfers and Basic Mobility, Global Function, and Happiness With Physical Condition. Gross Motor Function Classification System levels was a significant predictor of Transfers and Basic Mobility, Sports and Physical Function, and Global Function. Pattern of involvement, sex, and prior orthopaedic surgery were not statistically significant predictors for any of the Parent PODCI measures. Mean and SD scores were calculated for age groups stratified by GMFCS levels. Analysis of the follow-up data set validated the findings derived from the baseline data. Linear regression equations were derived, with age as a continuous variable and GMFCS levels as a categorical variable, to be used for Parent PODCI predicted scores. The results of this study provide clinicians and researchers with a set of Parent PODCI values for comparison to age- and severity-matched populations of ambulatory patients with CP.

Published nomograms of pediatric echocardiographic measurements are limited by insufficient sample size to assess the effects of age, sex, race, and ethnicity. Variable methodologies have resulted in a wide range of Z scores for a single measurement. This multicenter study sought to determine Z scores for common measurements adjusted for body surface area (BSA) and stratified by age, sex, race, and ethnicity. Data collected from healthy nonobese children ≤18 years of age at 19 centers with a normal echocardiogram included age, sex, race, ethnicity, height, weight, echocardiographic images, and measurements performed at the Core Laboratory. Z score models involved indexed parameters (X/BSA α ) that were normally distributed without residual dependence on BSA. The models were tested for the effects of age, sex, race, and ethnicity. Raw measurements from models with and without these effects were compared, and <5% difference was considered clinically insignificant because interobserver variability for echocardiographic measurements are reported as ≥5% difference. Of the 3566 subjects, 90% had measurable images. Appropriate BSA transformations (BSA α ) were selected for each measurement. Multivariable regression revealed statistically significant effects by age, sex, race, and ethnicity for all outcomes, but all effects were clinically insignificant based on comparisons of models with and without the effects, resulting in Z scores independent of age, sex, race, and ethnicity for each measurement. Echocardiographic Z scores based on BSA were derived from a large, diverse, and healthy North American population. Age, sex, race, and ethnicity have small effects on the Z scores that are statistically significant but not clinically important. © 2017 American Heart Association, Inc.

Two Sides of the Same Coin: Pediatric-Onset and Adult-Onset Common Variable Immune Deficiency.

Common variable immunodeficiency (CVID) is a complex, heterogeneous immunodeficiency characterized by hypogammaglobulinemia, recurrent infections, and poor antibody response to vaccination. While antibiotics and immunoglobulin prophylaxis have significantly reduced infectious complications, non-infectious complications of autoimmunity, inflammatory lung disease, enteropathy, and malignancy remain of great concern. Previous studies have suggested that CVID patients diagnosed in childhood are more severely affected by these complications than adults diagnosed later in life. We sought to discern whether the rates of various infectious and non-infectious conditions differed between pediatric-diagnosed (ages 17 or younger) versus adult-diagnosed CVID (ages 18 or older). Using the United States Immunodeficiency Network (USIDNET) database, we performed a retrospective analysis of 457 children and adults with CVID, stratified by age at diagnosis. Chi-squared testing was used to compare pediatric versus adult groups. After correcting for multiple comparisons, we identified few statistically significant differences (p ≤ 0.0004) between pediatric and adult groups. Pediatric-onset CVID patients had more frequent diagnoses of otitis media, developmental delay, and failure to thrive compared with adult-onset CVID patients. Adult CVID patients were more frequently diagnosed with bronchitis, arthritis, depression, and fatigue. Diagnoses of autoimmunity, lymphoma, and other malignancies were higher in adults but not to a significant degree. Serum immunoglobulins (IgG, IgA, and IgM) and lymphocyte subsets did not differ significantly between the two groups. When complications of infections and co-morbid conditions were viewed categorically, there were few differences between pediatric-onset and adult-onset CVID patients. These results suggest that pediatric CVID is not a distinct phenotype. Major features were comparable across the groups. This study underscores the need for continued longitudinal study of pediatric and early-onset CVID patients to further characterize accrual of features over time.

Objective To validate a diagnostic instrument for pediatric delirium in critically ill children, both ventilated and nonventilated, that uses standardized, developmentally appropriate measurements. Design and Setting A prospective observational cohort study investigating the Pediatric Confusion Assessment Method for Intensive Care Unit (pCAM-ICU) patients in the pediatric medical, surgical, and cardiac intensive care unit of a university-based medical center. Patients A total of 68 pediatric critically ill patients, at least 5 years of age, were enrolled from July 1, 2008, to March 30, 2009. Interventions None. Measurements Criterion validity including sensitivity and specificity and interrater reliability were determined using daily delirium assessments with the pCAM-ICU by two critical care clinicians compared with delirium diagnosis by pediatric psychiatrists using Diagnostic and Statistical Manual, 4th Edition, Text Revision criteria. Results A total of 146 paired assessments were completed among 68 enrolled patients with a mean age of 12.2 yrs. Compared with the reference standard for diagnosing delirium, the pCAM-ICU demonstrated a sensitivity of 83% (95% confidence interval, 66–93%), a specificity of 99% (95% confidence interval, 95–100%), and a high interrater reliability (κ = 0.96; 95% confidence interval, 0.74–1.0). Conclusions The pCAM-ICU is a highly valid reliable instrument for the diagnosis of pediatric delirium in critically ill children chronologically and developmentally at least 5 yrs of age. Use of the pCAM-ICU may expedite diagnosis and consultation with neuropsychiatry specialists for treatment of pediatric delirium. In addition, the pCAM-ICU may provide a means for delirium monitoring in future epidemiologic and interventional studies in critically ill children. (Crit Care Med 2011; 39:150–157) PMID:20959783

Congenital heart defects (CHDs) occur in approximately 8 per 1000 live births. Improvements in detection and treatment have increased survival. Few national estimates of the healthcare costs for infants, children and adolescents with CHDs are available. We estimated hospital costs for hospitalizations using pediatric (0-20 years) hospital discharge data from the 2009 Healthcare Cost and Utilization Project Kids' Inpatient Database (KID) for hospitalizations with CHD diagnoses. Estimates were up-weighted to be nationally representative. Mean costs were compared by demographic factors and presence of critical CHDs (CCHDs). Up-weighting of the KID generated an estimated 4,461,615 pediatric hospitalizations nationwide, excluding normal newborn births. The 163,980 (3.7%) pediatric hospitalizations with CHDs accounted for approximately $5.6 billion in hospital costs, representing 15.1% of costs for all pediatric hospitalizations in 2009. Approximately 17% of CHD hospitalizations had a CCHD, but it varied by age: approximately 14% of hospitalizations of infants, 30% of hospitalizations of patients aged 1 to 10 years, and 25% of hospitalizations of patients aged 11 to 20 years. Mean costs of CHD hospitalizations were higher in infancy ($36,601) than at older ages and were higher for hospitalizations with a CCHD diagnosis ($52,899). Hospitalizations with CCHDs accounted for 26.7% of all costs for CHD hospitalizations, with hypoplastic left heart syndrome, coarctation of the aorta, and tetralogy of Fallot having the highest total costs. Hospitalizations for children with CHDs have disproportionately high hospital costs compared with other pediatric hospitalizations, and the 17% of hospitalizations with CCHD diagnoses accounted for 27% of CHD hospital costs. © 2014 Wiley Periodicals, Inc.

The main aim of this study is to utilize the geographical information system (GIS) software and perform the spatial analysis in relation to clinical data for road traffic injury (RTI) pediatric cases attending the emergency department. The study sample included pediatric patients (age less than 18 years) with road-related injuries within a district in Malaysia who attended emergency departments of two tertiary hospitals within the district. In addition to injury, pre-hospital care and outcome data, the coordinate of the locations were obtained by the ambulance paramedics by using portable handheld GPS unit brand Garmin(®) model GPS 72 H. The data was transferred into the excel format which in turn underwent GIS analysis by using ARCGIS(®) (by ESRI) software version 10.1 licensed to the study institution. A total of 102 (24.8%) of all motor vehicle crash (MVC) victims involved the pediatric age group (age 18 years and below). The mean (SD) age of the pediatric victims was 14.30 years (SD 3.830). Male comprised of 68 (66.7%) of the cases. Motorcyclists [88 (88.0%)] were the most common type of victims involved. Interestingly, the majority of the severely injured victims [75 (73%)] sustained the RTI on roads with maximum speed limit of 60 km/hour. The mean (SD) length of hospital stay was 7.83 days (5.59). The pediatric related road traffic injury in Malaysia causes significant health and social burden in the country. This study showed both important clinical and geographical factors that need to be taken into consideration for future preventive action.

Background Dexmedetomidine, an α2-receptor agonist, provides potent sedation, analgesia, and anxiolysis without respiratory depression and is used in a variety of surgical and procedural situations. Aim of the review The aim of this study was to estimate the incidence of bradycardia in pediatric patients who received dexmedetomidine as a sole agent for any procedural, intensive care or surgical sedation. Method Literature was searched in electronic databases and studies were selected by following pre-determined eligibility criteria. Meta-analyses were carried out by pooling the percent incidence of bradycardia to attain a weighted overall effect size. Age-wise subgroup analyses and meta-regression analyses for the identification of factors affecting the incidence were also performed. Results Data of 2835 patients from 21 studies were included. The mean age was 62.21 ± 35.68 months. Initial, maintenance and total doses of dexmedetomidine (mean ± standard deviation) were 1.63 ± 0.33 μg/kg body weight, 0.86 ± 0.68 μg/kg/h, and 26.7 ± 20.8 μg/kg. The overall incidence of bradycardia (95% confidence interval) was 3.067 (2.863, 3.270)%; P < 0.0001. However, range was wider (0-22%) with 9 studies observed 0% incidence. The mean change in the heart rate was -17.26 (-21.60, -12.92); P < 0.00001. In the meta-regression analyses, age, body weight and dexmedetomidine dose were not significantly associated with the incidence of bradycardia. The minimum heart rate observed during the dexmedetomidine treatment period was positively associated with baseline heart rate. Conclusion Incidence of bradycardia in dexmedetomidine treated pediatric patients is 3%.

Multi-national findings on radiation protection of children.

This article reviews issues of radiation protection in children in 52 low-resource countries. Extensive information was obtained through a survey by the International Atomic Energy Agency (IAEA); wide-ranging information was available from 40 countries and data from the other countries pertained to frequency of pediatric CT examinations. Of note is that multi-detector CT (MDCT) was available in 77% of responses to the survey, typically nodal centers in these countries. Nearly 75% of these scanners were reported to have dose displays. The pediatric CT usage was lower in European facilities as compared to Asian and African facilities, where usage was twice as high. The most frequently scanned body part was the head. Frequent use of 120 kVp was reported in children. The ratio of maximum to minimum CT dose index volume (CTDIvol) values varied between 15 for abdomen CT in the age group 5-10 years and 100 for chest CT in the age group <1 year. In 8% of the CT systems, CTDI values for pediatric patients were higher than those for adults in at least one age group and for one type of examination. Use of adult protocols for children was associated with CTDIw or CTDIvol values in children that were double those of adults for head and chest examination and 50% higher for abdomen examination. Patient dose records were kept in nearly half of the facilities, with the highest frequency in Europe (55% of participating facilities), and in 49% of Asian, 36% of Latin American and 14% of African facilities. The analysis of the first-choice examinations in seven clinical conditions showed that practice was in accordance with guidelines for only three of seven specified clinical conditions.

Modifiable factors of health-related quality of life (HRQOL) are poorly described among children with advanced cancer. Symptom distress may be an important factor for intervention. We aimed to describe patient-reported HRQOL and its relationship to symptom distress. Prospective, longitudinal data from the multicenter Pediatric Quality of Life and Symptoms Technology study included primarily patient-reported symptom distress and HRQOL, measured at most weekly with the Memorial Symptoms Assessment Scale and Pediatric Quality of Life inventory, respectively. Associations were evaluated using linear mixed-effects models adjusting for sex, age, cancer type, intervention arm, treatment intensity, and time since disease progression. Of 104 enrolled patients, 49% were female, 89% were white, and median age was 12.6 years. Nine hundred and twenty surveys were completed over nine months of follow-up (84% by patients). The median total Pediatric Quality of Life score was 74 (interquartile range 63-87) and was "poor/fair" (e.g., <70) 38% of the time. "Poor/fair" categories were highest in physical (53%) and school (48%) compared to emotional (24%) and social (16%) subscores. Thirteen of 24 symptoms were independently associated with reductions in overall or domain-specific HRQOL. Patients commonly reported distress from two or more symptoms, corresponding to larger HRQOL score reductions. Neither cancer type, time since progression, treatment intensity, sex, nor age was associated with HRQOL scores in multivariable models. Among 25 children completing surveys during the last 12 weeks of life, 11 distressing symptoms were associated with reductions in HRQOL. Symptom distress is strongly associated with HRQOL. Future research should determine whether alleviating distressing symptoms improves HRQOL in children with advanced cancer. Copyright © 2016 American Academy of Hospice and Palliative Medicine.

Rationale: Limited data exist about the international burden of severe sepsis in critically ill children. Objectives: To characterize the global prevalence, therapies, and outcomes of severe sepsis in pediatric intensive care units to better inform interventional trials. Methods: A point prevalence study was conducted on 5 days throughout 2013–2014 at 128 sites in 26 countries. Patients younger than 18 years of age with severe sepsis as defined by consensus criteria were included. Outcomes were severe sepsis point prevalence, therapies used, new or progressive multiorgan dysfunction, ventilator- and vasoactive-free days at Day 28, functional status, and mortality. Measurements and Main Results: Of 6,925 patients screened, 569 had severe sepsis (prevalence, 8.2%; 95% confidence interval, 7.6–8.9%). The patients’ median age was 3.0 (interquartile range [IQR], 0.7–11.0) years. The most frequent sites of infection were respiratory (40%) and bloodstream (19%). Common therapies included mechanical ventilation (74% of patients), vasoactive infusions (55%), and corticosteroids (45%). Hospital mortality was 25% and did not differ by age or between developed and resource-limited countries. Median ventilator-free days were 16 (IQR, 0–25), and vasoactive-free days were 23 (IQR, 12–28). Sixty-seven percent of patients had multiorgan dysfunction at sepsis recognition, with 30% subsequently developing new or progressive multiorgan dysfunction. Among survivors, 17% developed at least moderate disability. Sample sizes needed to detect a 5–10% absolute risk reduction in outcomes within interventional trials are estimated between 165 and 1,437 patients per group. Conclusions: Pediatric severe sepsis remains a burdensome public health problem, with prevalence, morbidity, and mortality rates similar to those reported in critically ill adult populations. International clinical trials targeting children with severe sepsis are warranted. PMID:25734408

The purpose of this paper is to develop a robust and accurate method that automatically segments phalangeal and epiphyseal bones from digital pediatric hand radiographs exhibiting various stages of growth. The algorithm uses an object-oriented approach comprising several stages beginning with the most general objects to be segmented, such as the outline of the hand from background, and proceeding in a succession of stages to the most specific object, such as a specific phalangeal bone from a digit of the hand. Each stage carries custom operators unique to the needs of that specific stage which will aid in more accurate results. The method is further aided by a knowledge base where all model contours and other information such as age, race, and sex, are stored. Shape models, 1-D wrist profiles, as well as an interpretation tree are used to map model and data contour segments. Shape analysis is performed using an arc-length orientation transform. The method is tested on close to 340 phalangeal and epiphyseal objects to be segmented from 17 cases of pediatric hand images obtained from our clinical PACS. Patient age ranges from 2 - 16 years. A pediatric radiologist preliminarily assessed the results of the object contours and were found to be accurate to within 95% for cases with non-fused bones and to within 85% for cases with fused bones. With accurate and robust results, the method can be applied toward areas such as the determination of bone age, the development of a normal hand atlas, and the characterization of many congenital and acquired growth diseases. Furthermore, this method's architecture can be applied to other image segmentation problems.

In this study the authors evaluated the mechanisms and patterns of injury and the factors affecting management and outcome of pediatric subaxial cervical spine injuries (C3-7). Fifty-one pediatric patients (38 boys and 13 girls; mean age 12.4 years, range 10 months-16 years) with subaxial cervical spine injuries were reviewed retrospectively. Motor vehicle accidents (MVAs) were the most common cause of injury. Overall, 12% presented with a dislocation, 63% with a fracture, 19% with a fracture-dislocation, and 6% with a ligamentous injury. The most frequently injured level was C6-7 (33%); C3-4 (6%) was least frequently involved. Sixty-four percent of patients were neurologically intact, 16% had incomplete spinal cord injuries (SCIs), 14% had complete SCIs, and three patients (6%) died after admission and before assessment. Treatment was conservative in 64%: seven (13%) wore a halo vest and 26 (51%) wore a rigid cervical orthosis. Surgery was performed in the other 18 patients (36%), with the breakdown as follows: 15 (30%) underwent an anterior approach, two (4%) had posterior approaches, and one (2%) had a combined approach. Postoperatively, four patients (8% who had a neurological deficit improved. The overall mortality rate was 8%; all deaths were related to MVAs. There were no surgery-related deaths or complications. Subaxial cervical spine injuries are common in children 9 to 16 years of age, and occur principally between C-5 and C-7. Multilevel injury is more common in children 8 years of age and older than in younger children and infants. Most patients with subaxial cervical spine injuries can be treated conservatively. Both anterior and posterior approaches are safe and effective.

Data on pediatric HIV in Peru are limited. The National Institute of Child Health (Instituto Nacional de Salud del Niño: INSN) cares for the most HIV-infected children under the age of 18 years in the country. We describe the outcomes of children seen at INSN's HIV clinic over the 10 years when antiretroviral therapy and prevention of mother-to-child transmission (PMTCT) interventions became available in 2004. We conducted a retrospective review of INSN HIV clinic patients between 2003 and 2012. Deidentified data were collected and analyzed. A total of 280 children were included: 50.0% (140/280) were male; 80.0% (224/280) lived in metropolitan Lima. Perinatal transmission was the mode of HIV infection in 91.4% (256/280) of children. Only 17% (32/191) of mothers were known to be HIV-infected at delivery; of these mothers, 41% (13/32) were receiving antiretroviral therapy at delivery, 72% (23/32) delivered by Cesarean section and 47% (15/32) of their infants received antiretroviral prophylaxis. Median age at HIV diagnosis for all children was 35.7 months (interquartile range 14.5-76.8 months), and 67% (143/213) had advanced disease (clinical stage C). After HIV diagnosis, the most frequent hospitalization discharge diagnoses were bacterial pneumonia, chronic malnutrition, diarrhea, anemia and tuberculosis. Twenty-four patients (8.6%) died at a median age of 77.4 months. Most cases of pediatric HIV were acquired via perinatal transmission; few mothers were diagnosed before delivery; and among mothers with known HIV status, PMTCT was suboptimal even after national PMTCT policy was implemented. Most children were diagnosed with advanced disease. These findings underscore the need for improving early pediatric HIV diagnosis and treatment, as well as PMTCT strategies.

Objective: A retrospective study was designed to evaluate the results of surgical treatment and follow-up data in thyroid cancer patients less than 15 years old at the time of surgery. Summary Background Data: Pediatric thyroid carcinomas have a high rate of lymph nodal and distant metastases. Risk factors for recurrences and postoperative morbidity have not been assessed yet in a representative series. Methods: The group included 740 pediatric patients with thyroid cancer. Total thyroidectomy was performed in 426 (57.6%), lobectomy in 248 (33.5%), subtotal thyroidectomy in 58 (7.8%) cases, and 8 patients (1.1%) underwent partial lobectomy. Results: The mean follow-up period was 115.8 months (range, 1.5–236.4 months). Recurrence was diagnosed in 204 cases (27.6%), including 73 local relapses (9.9%), 90 distant metastases (12.2%), and a combination of local and distant recurrences in 41 (5.5%) patients. Multivariate statistical assessment revealed the following independent parameters significantly associated with the risk of recurrent nodal disease: a young age at diagnosis, multifocal carcinomas, N1 status, and lack of neck lymph node dissection. For lung metastases, the significant risk factors were female gender, young age at diagnosis, and presence of symptoms. The observed 5- and 10-year survival for the entire group was 99.5% and 98.8%, respectively. Postoperative hypoparathyroidism was significantly associated with multifocal tumors, central compartment removal, and ipsilateral dissection. Conclusions: Total thyroidectomy followed by radioiodine therapy is an optimal treatment strategy that makes it possible to achieve a cure in a vast majority of pediatric patients with differentiated thyroid carcinomas. Risk of recurrence is strongly associated with tumor stage, extent of surgery, the young patient's age, and presence of symptoms at diagnosis. PMID:16552205

Pharmacokinetic properties and tolerability of single-dose terbutaline in patients with severe asthma treated in the pediatric intensive care unit

Background: Asthmatic children requiring treatment in the pediatric intensive care unit (PICU) receive aggressive drug therapy that may include IV administration of β2-receptor agonists to prevent progression to life-threatening respiratory failure. The only pharmacologic agent in this class currently available for parenteral use in the United States is terbutaline. Study of IV dosing of terbutaline in the pediatric population has been limited. Objective: The aim of this study was to determine the pharmacokinetic (PK) properties and tolerability of single-dose terbutaline in pediatric patients across a broad age range who were admitted to the PICU and were receiving maximal conventional asthma drug therapy. Methods: This study was conducted at the PICU at Rainbow Babies and Children's Hospital (Cleveland, Ohio). Patients aged 6 months to 16 years with severe exacerbation of reactive airways disease and who were undergoing maximal conventional therapy and had an arterial catheter were enrolled. Patients were arbitrarily assigned to receive a single IV infusion of 1 of 3 doses of terbutaline (10, 20, or 30 μg/kg), infused over 5 minutes. Blood samples were obtained for the determination of plasma terbutaline concentrations just before terbutaline was administered (baseline), immediately on completion of the IV infusion, and at 10, 20, and 40 minutes and 1, 2, 4, 8, 16, 32, 48, and 72 hours after the 5-minute infusion. PK properties (elimination half-life [tl2], mean residence time [MRT], apparent steady-state volume of distribution [Vdss], and total body clearance [CI]) were determined and adverse effects were recorded. Results: The determination of terbutaline PK properties was possible in 50 of 56 enrolled patients (31 boys, 19 girls; mean [SD] age, 6.5 [4.5] years). The PK properties of terbutaline were linear over the dose range studied and, with the exception of the expected dose-dependent increases in peak terbutaline plasma concentration and area under the terbutaline plasma concentration-time curve, no statistically significant differences were observed in PK relative to dose. Therefore, we pooled the data for all subsequent analyses. Statistically significant correlations with patient age were observed with tl2 (r = 0.4, P < 0.006), MRT (r = 0.4, P < 0.002), and Vdss (r = 0.33, P < 0.02), but not C1 (r = −0.03, P = NS). Single-dose terbutaline administration was generally well tolerated. Conclusions: Single-dose IV terbutaline was well tolerated in this study. In maximally treated asthmatic patients in the PICU, terbutaline elimination may be more rapid than in nonacutely ill children. These PK data suggest that if the drug is to be administered intravenously, the continuous IV infusion method, including loading doses for any subsequent dose escalations, may be the most appropriate. The influence of age and safety of long-term, continuous terbutaline IV infusion requires further study. PMID:24936108

This study describes information from the National Automotive Sampling System for injury mechanisms in the pediatric age group (age 0–16). The total number of pediatric cases in the NASS database for this three year sampling period is 2141(weighted 591,084). No restraint use was identified in 23–43% of the children. For age < 1yr, 60% of patients suffer a facial injury. Head injuries make up only 10% of the total injuries, but are severe. For those age 1–4 yrs abdominal injuries and lower extremity injuries begin to appear. For those age 5–10 yrs, the predominant change over younger occupants is the proportion of spinal injuries. By age 11–16, injuries to the spine, upper extremities, and lower extremities outnumber injuries to the face and head. However, in this population, the greatest proportions of AIS 3–5 injuries still occur to the head and abdomen.

To compare the effectiveness of open reduction and conservative treatment for pediatric mandibular condylar fractures and to provide the evidence for the selection of clinical therapy. The clinical data were retrospectively analyzed from 25 patients with the mandibular condylar fractures between January 1988 and December 2006. Of them, 8 patients (11 fractures) were treated with surgical treatment (surgical group) and 17 patients (22 fractures) with non-surgical treatment (non-surgical group). In surgical group, there were 6 males (9 fractures) and 2 females (2 fractures) with an age range of 8-13 years; fracture was caused by tumbling in 7 cases and by traffic accident in 1 with an interval of 1-6 days between injury and hospitalization; and 5 cases were identified as unilateral condylar fractures (3 complicated by mental fractures) and 3 cases as bilateral condylar fractures complicated by mental fractures. In non-surgical group, there were 12 males (15 fractures) and 5 females (7 fractures) with an age range of 3-12 years; fracture was caused by falling from height in 4 cases, by tumbling in 10, and by traffic accident in 3 with an interval of 1-25 days between injury and hospitalization; and 12 cases were identified as unilateral condylar fractures (3 complicated by mental fractures) and 5 cases as bilateral condylar fractures (1 complicated by mental fracture). Incision healed by first intention in surgical group, and 25 cases were followed up 1-6 years with an average of 3.5 years. At 12 months after treatment, no temporomandibular joint pain, eating disorder, or limited mandibular movement occurred in 2 groups. No significant difference was observed in opening mouth extent, protrusive and lateral movements between 2 groups at 6 and 12 months (P > 0.05). During centric occlusion, mental point located at the midline with symmetric face figure. Two patients in surgical group and 3 in non-surgical group had slight snap when opening their mouths. Mandible deviation was observed in 3 patients of 2 groups, respectively when gaping. The X-ray films showed healing of fracture and condylar remodeling at 3-6 months. Mandibular ramus were symmetric in cephalometry. Good effectiveness can be obtained by surgical or non-surgical treatment in pediatric mandibular condylar fractures. Considering the pediatric mandibular condyle having powerful healing and reconstructing potency and avoiding secondary injury on the temporomandibular joint from surgery, non-surgical treatment should be first selected for the pediatric mandibular condylar fractures in patients under 7 years.

This study evaluated factors associated with increased risk of pulmonary toxicity (PT) from any cause in pediatric patients after myeloablative conditioning, using total body irradiation (TBI), followed by allogeneic hematopoietic stem cell transplantation (HSCT). The records of 129 consecutive pediatric patients (range: 1-21 years of age) who underwent TBI-based myeloablative conditioning for hematologic malignancies at our institution between January 2003 and May 2014 were reviewed. Although total TBI doses ranged from 10.5 to 14 Gy, lung doses were limited to 10 Gy with partial transmission blocks. TBI dose rates ranged from 5.6 cGy/min to 20.9 cGy/min. PT was classified using clinical symptoms, radiographic evidence, and ventilatory defects on pulmonary function tests. Noninfectious (idiopathic) pneumonia syndrome (IPS) was characterized by patients exhibiting PT while demonstrating no signs of infection throughout the follow-up period. PT from any cause developed in 70.5% of patients and was significantly associated with increased transplantation-related mortality (TRM) (P=.03) and decreased overall survival (OS) (P=.02). IPS developed in 23.3% of patients but was not associated with increased TRM (P=.6) or decreased OS (P=.5). Acute graft-versus-host disease (GVHD) significantly affected PT (P=.001) but did not significantly influence the development of IPS (P=.4). Infection was a leading cause of PT (75.8%). TBI dose rate significantly affected development of overall PT (P=.02) and was the sole factor to significantly influence the incidence of IPS (P=.002). TBI total dose, dose per fraction, disease type, transplantation chemotherapy, age of patient, sex, and donor type did not significantly impact overall PT or IPS. A high incidence of PT was noted in this large series of homogeneously treated pediatric patients undergoing TBI for allogeneic HSCT. TBI dose rates affected overall PT and strongly influenced IPS. TBI dose rate is a contributing factor influencing pulmonary toxicity and rates less than 15 cGy/min should be considered to decrease the risk of IPS. Copyright © 2016 Elsevier Inc.

Craniopharyngiomas can be a surgical challenge for the pediatric neurosurgeon. Ideally, total removal must be achieved. However, the need to reduce surgical morbidity and preserve quality of life has led to a number of neurosurgical approaches in order to attain this goal. The aim of this article is to present an alternative surgical approach to these lesions and to provide the rationale for this technique. Medical charts and operative records of eight pediatric patients harboring craniopharyngiomas who underwent surgical treatment using a supraorbital eyebrow approach (SOA) were reviewed from 2014 to 2016. Only patients younger than 18 years with a minimum follow-up of 12 months were included in this study. Using pre-operative magnetic resonance (MRI) scans, tumors were classified according to their degree of hypothalamic involvement. The surgical technique is also described in detail. The study group included six males and two females with a mean age of 10 years (range, 2-16 years). The SOA was used successfully in elective surgery of eight craniopharyngiomas. The hypothalamus was displaced by the tumor in three patients and severely involved in five patients. Subtotal resection was undertaken in six patients, whereas gross-total resection was achieved in two. Endoscopic assistance was used after standard microscopic visualization in two out of eight cases. Cosmetic outcomes were excellent, and the complication rate related to the surgical procedure was quite low, apart from diabetes insipidus (which occurred in three out of the eight patients). In one patient, a large subdural collection needed surgery for evacuation. Mean follow-up was 23.2 months (range, 12-36 months). Additionally, no CSF leak or wound infection was identified. The supraorbital eyebrow approach is an alternative route to operate on craniopharyngiomas in properly selected cases of all pediatric age ranges, from infants to teenagers. There is sufficient working space for the endoscope and all instruments, allowing for endoscopic assistance and bimanual surgical technique. Cosmetic results are excellent, and complications related to the approach are minimal.

We attempted to describe the opioid prescribing patterns for ambulatory pediatric surgery in the United States from 2007 to 2014. Retrospective database review. Operating room ambulatory encounters as determined by the Truven Health Marketscan Commercial Claims and Encounters database. A total of 929,874 ambulatory surgical encounters were identified in patients <18years of age and, of these, 439,286 encounters generated an analgesic prescription. N/A MEASUREMENTS: The analgesic prescription was described in terms of the type of opioid along with the inclusion of acetaminophen and/or NSAIDs. The probability of receiving a post-operative analgesic prescription increased with age, ranging from 18.2% of infants to 71.7% of teens. Acetaminophen with codeine (APAP/C) was the most common drug for infants (63.8%), while acetaminophen with hydrocodone (APAP/H) was the most common analgesic prescription for teens (53.6%). APAP/C and APAP/H were the predominant drugs used for all procedure types. Substantial variability in analgesic prescribing at the level of the procedure performed, both in terms of the probability of receiving a prescription and in which drugs were prescribed. We observed significant age and procedure-based variability in opioid prescribing following pediatric ambulatory surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

Are there differences in brain morphometry between twins and unrelated singletons? A pediatric MRI study.

2010-04-01

Twins provide a unique capacity to explore relative genetic and environmental contributions to brain development, but results are applicable to non-twin populations only to the extent that twin and singleton brains are alike. A reason to suspect differences is that as a group twins are more likely than singletons to experience adverse prenatal and perinatal events that may affect brain development. We sought to assess whether this increased risk leads to differences in child or adolescent brain anatomy in twins who do not experience behavioral or neurological sequelae during the perinatal period. Brain MRI scans of 185 healthy pediatric twins (mean age = 11.0, SD = 3.6) were compared to scans of 167 age- and sex-matched unrelated singletons on brain structures measured, which included gray and white matter lobar volumes, ventricular volume, and area of the corpus callosum. There were no significant differences between groups for any structure, despite sufficient power for low type II (i.e. false negative) error. The implications of these results are twofold: (1) within this age range and for these measures, it is appropriate to include healthy twins in studies of typical brain development, and (2) findings regarding heritability of brain structures obtained from twin studies can be generalized to non-twin populations.

Purpose: To investigate the correlation of size-specific dose estimate (SSDE) with absorbed organ dose, and to develop a simple methodology for estimating patient organ dose in a pediatric population (5–55 kg). Methods: Four physical anthropomorphic phantoms representing a range of pediatric body habitus were scanned with metal oxide semiconductor field effect transistor (MOSFET) dosimeters placed at 23 organ locations to determine absolute organ dose. Phantom absolute organ dose was divided by phantom SSDE to determine correlation between organ dose and SSDE. Organ dose correlation factors (\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{upgreek} \\usepackage{mathrsfs} \\setlength{\\oddsidemargin}{-69pt} \\begin{document} }{}${\\rm CF}_{{\\rm SSDE}}^{{\\rm organ}}$\\end{document} CF SSDE organ ) were then multiplied by patient-specific SSDE to estimate patient organ dose.

Asthma is a chronic disease that can result in exacerbations leading to urgent care in emergency departments (EDs) and hospitals. We examined seasonal and temporal trends in pediatric asthma ED (1997-1999) and hospital (1986-1999) admission data so as to identify periods of increased risk of urgent care by age group, gender, and race. All pediatric ED and hospital admission data for Maryland residents occurring within the state of Maryland were evaluated. Distinct peaks in pediatric ED and hospital asthma admissions occurred each year during the winter-spring and autumn seasons. Although the number and timing of these peaks were consistent across age and racial groups, the magnitude of the peaks differed by age and race. The same number, timing, and relative magnitude of the major peaks in asthma admissions occurred statewide, implying that the variables affecting these seasonal patterns of acute asthma exacerbations occur statewide. Similar gross seasonal trends are observed worldwide. Although several environmental, infectious, and psychosocial factors have been linked with increases in asthma exacerbations among children, thus far they have not explained these seasonal patterns of admissions. The striking temporal patterns of pediatric asthma admissions within Maryland, as described here, provide valuable information in the search for causes.

Pediatric sepsis is distinct from adult sepsis in its definitions, clinical presentations, and management. Recognition of pediatric sepsis is complicated by the various pediatric-specific comorbidities that contribute to its mortality and the age- and development-specific vital sign and clinical parameters that obscure its recognition. This article outlines the clinical presentation and management of sepsis in neonates, infants, and children, and highlights some key populations who require specialized care.

This study investigates the effects of pediatric aquatic therapy on motor function, enjoyment, activities of daily living, and health-related quality of life for children with spastic cerebral palsy of various motor severities. Children with spastic cerebral palsy were assigned to a pediatric aquatic therapy group (n = 11; mean age = 85.0 ± 33.1 months; male : female = 4 : 7) or a control group (n = 13; mean age = 87.6 ± 34.0 months; male : female = 9 : 4). The statistic results indicate that the pediatric aquatic therapy group had greater average 66-item Gross Motor Function Measure following intervention than the control group (η(2) = 0.308, P = .007), even for children with Gross Motor Function Classification System level IV (5.0 vs 1.3). The pediatric aquatic therapy group had higher Physical Activity Enjoyment Scale scores than the control group at post-treatment (P = .015). These findings demonstrate that pediatric aquatic therapy can be an effective and alternative therapy for children with cerebral palsy even with poor Gross Motor Function Classification System level. © The Author(s) 2014.

Identification of the prognostic factors for survival in patients with liver transplantation is challengeable. Various methods of survival analysis have provided different, sometimes contradictory, results from the same data. To compare Cox's regression model with parametric models for determining the independent factors for predicting adults' and pediatrics' survival after liver transplantation. This study was conducted on 183 pediatric patients and 346 adults underwent liver transplantation in Namazi Hospital, Shiraz, southern Iran. The study population included all patients undergoing liver transplantation from 2000 to 2012. The prognostic factors sex, age, Child class, initial diagnosis of the liver disease, PELD/MELD score, and pre-operative laboratory markers were selected for survival analysis. Among 529 patients, 346 (64.5%) were adult and 183 (34.6%) were pediatric cases. Overall, the lognormal distribution was the best-fitting model for adult and pediatric patients. Age in adults (HR=1.16, p<0.05) and weight (HR=2.68, p<0.01) and Child class B (HR=2.12, p<0.05) in pediatric patients were the most important factors for prediction of survival after liver transplantation. Adult patients younger than the mean age and pediatric patients weighing above the mean and Child class A (compared to those with classes B or C) had better survival. Parametric regression model is a good alternative for the Cox's regression model.

Laryngeal mask is frequently the airway device of choice in routine general anesthesia for many procedures in children. Several studies have described the use of laryngeal masks in unconventional situations. This survey was undertaken to assess how laryngeal masks are being used by pediatric anesthesiologists. The 40-question electronic survey using SurveyMonkey™ was sent to 2740 members of the Society for Pediatric Anesthesia (SPA). This survey assessed the age, work environment, types of practice, and training levels, as well as clinical situations in which the practitioners use laryngeal masks across different pediatric age groups. Seven hundred and forty-three (27.1%) responses were obtained. The use of laryngeal mask increased as the patient age increased in nearly every queried situation. The practitioners routinely utilize laryngeal masks in a variety of challenging scenarios, such as in patients with a recent upper respiratory infection, in the difficult airway, remote locations, and long-duration surgeries. A small percentage of pediatric anesthesiologists use laryngeal masks in laparoscopic surgery and prone position procedures. Pediatric anesthesiologists are using laryngeal masks in both routine and challenging/unconventional situations. Although many of the uses for laryngeal masks are not explicitly stated in the manufacturer guidelines, literature and current practice support the use of laryngeal masks in several of these scenarios. © 2015 John Wiley & Sons Ltd.

Psoriasis has been shown to be associated with cardiovascular disease in adults. Little is known about cardiovascular risk in pediatric psoriasis. To determine if there is an association between pediatric psoriasis and cardiovascular comorbidities. Data were analyzed from the 2002-2012 Nationwide Inpatient Sample, which included 4,884,448 hospitalized children aged 0-17 years. Bivariate and multivariate survey logistic regression models were created to calculate the odds of psoriasis on cardiovascular comorbidities. In multivariate survey logistic regression models adjusting for age, sex, and race/ethnicity, pediatric psoriasis was significantly associated with 5 of 10 cardiovascular comorbidities (adjusted odds ratio [95% confidence interval]), including obesity (3.15 [2.46-4.05]), hypertension (2.63 [1.93-3.59]), diabetes (2.90 [1.90-4.42]), arrhythmia (1.39 [1.02-1.88]), and valvular heart disease (1.90 [1.07-3.37]). The highest odds of cardiovascular risk factors occurred in blacks and Hispanics and children ages 0-9 years, but there were no sex differences. The study was limited to hospitalized children. We were unable to assess the impact of psoriasis treatment or family history on cardiovascular risk. Pediatric psoriasis is associated with higher odds of multiple cardiovascular comorbidities among hospitalized patients. Strategies for mitigating excess cardiovascular risk in pediatric psoriasis need to be determined. Copyright © 2017 American Academy of Dermatology, Inc. Published by Elsevier Inc.
