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.

Several enterovirus (EV) genotypes can result in aseptic meningitis, but their routes of access to the central nervous system remain to be elucidated and may differ between the pediatric and adult populations. To assess the pattern of viral shedding in pediatric and adult subjects with acute EV meningitis and to generate EV surveillance data for Switzerland. All pediatric and adult subjects admitted to the University Hospitals of Geneva with a diagnosis of EV meningitis between 2013 and 2015 were enrolled. A quantitative EV real-time reverse transcriptase (rRT)-PCR was performed on the cerebrospinal fluid (CSF), blood, stool, urine and respiratory specimens to assess viral shedding and provide a comparative analysis of pediatric and adult populations. EV genotyping was systematically performed. EV positivity rates differed significantly between pediatric and adult subjects; 62.5% of pediatric cases (no adult case) were EV-positive in stool and blood for subjects for whom these samples were all collected. Similarly, the EV viral load in blood was significantly higher in pediatric subjects. Blood C-reactive protein levels were lower and the number of leucocytes/mm 3 in the CSF were higher in non-viremic than in viremic pediatric subjects, respectively. A greater diversity of EV genotypes was observed in pediatric cases, with a predominance of echovirus 30 in children ≥3 years old and adults. In contrast to adults, EV-disseminated infections are predominant in pediatric subjects and show different patterns of EV viral shedding. This observation may be useful for clinicians and contribute to modify current practices of patient care. Copyright © 2017 The Author(s). Published by Elsevier B.V. All rights reserved.

In 2010, 8.6 million children were treated for unintentional injuries in American emergency departments. Child engagement in sports and recreation offers many health benefits but also exposure to injury risks. In this analysis, we consider possible developmental risk factors in a review of age, sex, and incidence of 39 sport and recreational injuries. To assess (1) how the incidence of 39 sport and recreational injuries changed through each year of child and adolescent development, ages 1 to 18 years, and (2) sex differences. Design : Descriptive epidemiology study. Emergency department visits across the United States, as reported in the 2001-2008 National Electronic Injury Surveillance System database. Data represent population-wide emergency department visits in the United States. Main Outcome Measure(s) : Pediatric sport- and recreation-related injuries requiring treatment in hospital emergency departments. Almost 37 pediatric sport or recreational injuries are treated hourly in the United States. The incidence of sport- and recreation-related injuries peaks at widely different ages. Team-sport injuries tend to peak in the middle teen years, playground injuries peak in the early elementary ages and then drop off slowly, and bicycling injuries peak in the preteen years but are a common cause of injury throughout childhood and adolescence. Bowling injuries peaked at the earliest age (4 years), and injuries linked to camping and personal watercraft peaked at the oldest age (18 years). The 5 most common causes of sport and recreational injuries across development, in order, were basketball, football, bicycling, playgrounds, and soccer. Sex disparities were common in the incidence of pediatric sport and recreational injuries. Both biological and sociocultural factors likely influence the developmental aspects of pediatric sport and recreational injury risk. Biologically, changes in perception, cognition, and motor control might influence injury risk. Socioculturally

Pediatric white matter disorders can be distinguished into well-defined leukoencephalopathies, and undefined leukoencephalopathies. The first category may be subdivided into: (a) hypomyelinating disorders; (b) dysmyelinating disorders; (c) leukodystrophies; (d) disorders related to cystic degeneration of myelin; and (e) disorders secondary to axonal damage. The second category, representing up to 50% of leukoencephalopathies in childhood, requires a multidisciplinar approach in order to define novel homogeneous subgroups of patients, possibly representing "new genetic disorders" (such as megalencephalic leukoencepahlopathy with subcortical cysts and vanishing white matter disease that have recently been identified). In the majority of cases, pediatric white matter disorders are inherited diseases. An integrated description of the clinical, neuroimaging and pathophysiological features is crucial for categorizing myelin disorders and better understanding their genetic basis. A review of the genetic disorders affecting white matter in the pediatric age, including some novel entities, is provided. Copyright 2004 Wiley-Liss, Inc.

Objectives The primary objective of this study was to investigate the pharmacokinetic profile of gadoterate meglumine in pediatric patients younger than 2 years; the secondary objectives were to document its efficacy and safety. Material and Methods This was a Phase IV open-label, prospective study conducted in 9 centers (4 countries). Forty-five patients younger than 2 years with normal estimated glomerular filtration rate and scheduled to undergo routine gadolinium-enhanced magnetic resonance imaging (MRI) of any organ were included and received a single intravenous injection of gadoterate meglumine (0.1 mmol/kg). To perform the population pharmacokinetics analysis, 3 blood samples per subject were drawn during 3 time windows at time points allocated by randomization. Results Gadoterate meglumine concentrations were best fitted using a 2-compartmental model with linear elimination from central compartment. The median total clearance adjusted to body weight was estimated at 0.06 L/h per kg and increased with estimated glomerular filtration rate according to a power model. The median volume of distribution at steady state (Vss) adjusted to body weight was estimated at 0.047 L/kg. Estimated median terminal half-life (t1/2β) was 1.35 h, and the median systemic exposure (area under the curve) was 1591 μmol h/L. Efficacy was assessed by comparing precontrast +postcontrast images to precontrast images in a subset of 28 subjects who underwent an MRI examination of brain, spine, and associated tissues. A total of 28 lesions were identified and analyzed in 15 subjects with precontrast images versus 30 lesions in 16 subjects with precontrast + postcontrast images. Lesion visualization was improved with a mean (SD) increase in scores at subject level of 0.7 (1.0) for lesion border delineation, 0.9 (1.6) for internal morphology, and 3.1 (3.2) for contrast enhancement. Twenty-six adverse events occurred postinjection in 13 subjects (28.9%), including 3 serious reported in 1

To determine if children with benign joint hypermobility (BJH) syndrome and chronic functional pain disorders have more autonomic dysfunction. Retrospective chart review study of pediatric patients seen in the pediatric neurogastroenterology and autonomic clinic who underwent autonomic testing and had either a Beighton score of ≥6 and met Brighton criteria for BJH (with BJH) or a score of ≤2 (no BJH). Twenty-one female subjects (10 without BJH) met inclusion criteria; 64% of BJH had diagnosis confirmed by genetics consultation. We evaluated for postural tachycardia syndrome, syncope, orthostatic intolerance, and orthostatic hypotension. None of these diagnoses, as well as baseline heart rate, peak heart rate in first 10 minutes of head up tilt (P = .35 and P = .61, respectively), and sudomotor index (suggestive of autonomic neuropathy) (P = .58), showed differences between the groups. Age of onset of symptoms was also similar (P = .61) (BJH vs without BJH: median [range]:15.6 years [12.9-17.5] vs 15.4 years [11.1-18.2]). There was no difference between groups in complaints of migraine, chronic nausea, chronic fatigue, lightheadedness, dizziness, fainting >3 times/lifetime, delayed onset of sleep, irritable bowel syndrome, dyspepsia, abdominal migraine, functional abdominal pain, constipation, or fibromyalgia. Children with chronic functional pain disorders and BJH have autonomic testing findings and comorbid features compared with a similar cohort of subjects without BJH, suggesting that BJH is not the driver of the autonomic and comorbid disorders.

OBJECTIVE Our understanding of pediatric cervical spine development remains incomplete. The purpose of this analysis was to quantitatively define cervical spine growth in a population of children with normal CT scans. METHODS A total of 1458 children older than 1 year and younger than 18 years of age who had undergone a cervical spine CT scan at the authors' institution were identified. Subjects were separated by sex and age (in years) into 34 groups. Following this assignment, subjects within each group were randomly selected for inclusion until a target of 15 subjects in each group had been measured. Linear measurements were performed on the midsagittal image of the cervical spine. Twenty-three unique measurements were obtained for each subject. RESULTS Data showed that normal vertical growth of the pediatric cervical spine continues up to 18 years of age in boys and 14 years of age in girls. Approximately 75% of the vertical growth occurs throughout the subaxial spine and 25% occurs across the craniovertebral region. The C-2 body is the largest single-segment contributor to vertical growth, but the subaxial vertebral bodies and disc spaces also contribute. Overall vertical growth of the cervical spine throughout childhood is dependent on individual vertebral body growth as well as vertical growth of the disc spaces. The majority of spinal canal diameter growth occurs by 4 years of age. CONCLUSIONS The authors' morphometric analyses establish parameters for normal pediatric cervical spine growth up to 18 years of age. These data should be considered when evaluating children for potential surgical intervention and provide a basis of comparison for studies investigating the effects of cervical spine instrumentation and fusion on subsequent growth.

Recent transcriptomic studies describe two subgroups of adults with sepsis differentiated by a sepsis response signature. The implied biology and related clinical associations are comparable with recently reported pediatric sepsis endotypes, labeled "A" and "B." We classified adults with sepsis using the pediatric endotyping strategy and the sepsis response signature and determined how endotype assignment, sepsis response signature membership, and age interact with respect to mortality. Retrospective analysis of publically available transcriptomic data representing critically ill adults with sepsis from which the sepsis response signature groups were derived and validated. Multiple ICUs. Adults with sepsis. None. Transcriptomic data were conormalized into a single dataset yielding 549 unique cases with sepsis response signature assignments. Each subject was assigned to endotype A or B using the expression data for the 100 endotyping genes. There were 163 subjects (30%) assigned to endotype A and 386 to endotype B. There was a weak, positive correlation between endotype assignment and sepsis response signature membership. Mortality rates were similar between patients assigned endotype A and those assigned endotype B. A multivariable logistic regression model fit to endotype assignment, sepsis response signature membership, age, and the respective two-way interactions revealed that endotype A, sepsis response signature 1 membership, older age, and the interactions between them were associated with mortality. Subjects coassigned to endotype A, and sepsis response signature 1 had the highest mortality. Combining the pediatric endotyping strategy with sepsis response signature membership might provide complementary, age-dependent, biological, and prognostic information.

 Since hospitalization can be a traumatic event for children, many of them may suffer from a cluster of chronic psychological and emotional difficulties called Pediatric Medical Traumatic Stress (PMTS). Although PMTS causes considerable functional impairment and psychological distress and may decrease the children's compliance with post-surgical care, awareness of this condition is low and thus not enough effort is made to prevent it. The objective of this study is to assess prospectively the prevalence and characteristics of PMTS in school-age children following hospitalization in a general pediatric surgery ward and in their parents, which has not been documented before.  We recruited parents of 88 children aged 6 to 13 years old, hospitalized in a pediatric surgery ward and which form a representative sample of the children of this age in the ward. Three to five months after discharge from the hospital, the parents completed questionnaires measuring symptoms of psychological distress.  About 26.4% of children displayed symptoms of PMTS, and 11.6% of parents suffered from posttraumatic stress disorder following their child's hospitalization. Moreover, we found a medium high positive correlation between the parents' level of distress and that of their child.  In view of the prevalence of PMTS among school-aged children following surgical intervention, it is necessary to promote increased awareness, preventive interventions, and early identification and treatment of this condition.

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

Biological covariates such as age and sex can markedly influence biochemical marker reference values, but no comprehensive study has examined such changes across pediatric, adult, and geriatric ages. The Canadian Health Measures Survey (CHMS) collected comprehensive nationwide health information and blood samples from children and adults in the household population and, in collaboration with the Canadian Laboratory Initiative on Pediatric Reference Intervals (CALIPER), examined biological changes in biochemical markers from pediatric to geriatric age, establishing a comprehensive reference interval database for routine disease biomarkers. The CHMS collected health information, physical measurements, and biosamples (blood and urine) from approximately 12 000 Canadians aged 3-79 years and measured 24 biochemical markers with the Ortho Vitros 5600 FS analyzer or a manual microplate. By use of CLSI C28-A3 guidelines, we determined age- and sex-specific reference intervals, including corresponding 90% CIs, on the basis of specific exclusion criteria. Biochemical marker reference values exhibited dynamic changes from pediatric to geriatric age. Most biochemical markers required some combination of age and/or sex partitioning. Two or more age partitions were required for all analytes except bicarbonate, which remained constant throughout life. Additional sex partitioning was required for most biomarkers, except bicarbonate, total cholesterol, total protein, urine iodine, and potassium. Understanding the fluctuations in biochemical markers over a wide age range provides important insight into biological processes and facilitates clinical application of biochemical markers to monitor manifestation of various disease states. The CHMS-CALIPER collaboration addresses this important evidence gap and allows the establishment of robust pediatric and adult reference intervals. © 2015 American Association for Clinical Chemistry.

Tinea pedis is the most common superficial fungal infection. Naftifine hydrochloride is a topical antifungal of the allylamine class, displaying fungicidal activity and clinically significant anti-bacterial and anti-inflammatory effects. Clinical data on topical antifungal therapy using naftifine for tinea pedis in a pediatric population is limited. To assess trends in efficacy, tolerability, safety, and to quantify the pharmacokinetics (PK) of topical naftifine hydrochloride gel 2% in pediatric subjects with tinea pedis. Twenty-eight subjects (22 pediatric and 6 adult controls) were enrolled and treated in the study. Approximately 2 grams of naftifine hydrochloride gel 2% was applied to each foot (4 grams total) for subjects with tinea pedis. Pharmacokinetic blood and urine samples were collected at various time points throughout the study. Efficacy was assessed based on potassium hydroxide, dermatophyte culture, and signs and symptom results at days 7, 14, and 28. Adverse event information was collected routinely.
The rate and extent of systemic exposure among the pediatric and adult control subjects was low. Adverse events were minimal and were not related to treatment. Positive results were observed as early as day 7; however the proportion of subjects achieving success generally increased over time through day 28 in both treatment groups. Naftifine hydrochloride gel 2% was found to be well tolerated and safe. Trends in clinical benefit were observed throughout the treatment period; however, continued improvement in efficacy rates were observed during the post-treatment period.

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

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 good knowledge of safety and age group-specific pharmacokinetics (PK) of antiepileptic drugs (AEDs) in young pediatric patients is of great importance in clinical practice. This paper presents 6-month interim safety and PK from an ongoing 2-year open-label study (Study 303) of adjunctive rufinamide treatment in pediatric subjects ≥ 1 to < 4 years with inadequately controlled epilepsies of the Lennox-Gastaut syndrome (LGS) spectrum. Subjects (N = 37) were randomized to either rufinamide or any other approved AED chosen by the investigator as adjunctive therapy to the subject's existing regimen of 1-3 AEDs. Interim safety results showed that treatment-emergent adverse events (TEAEs) were similar between the rufinamide (22 [88.0%]) and any-other-AED group (9 [81.8%]), with most events considered mild or moderate. A population PK analysis was conducted including plasma rufinamide concentrations from Study 303 and two other study populations of LGS subjects ≥ 4 years. The rufinamide PK profile was dose independent. The apparent clearance (CL/F) estimated from the PK model was 2.19 L/h; it was found to increase significantly as a function of body weight. Coadministration of valproic acid significantly decreased rufinamide CL/F. CL/F was not significantly affected by other concomitant AEDs, age, gender, race, hepatic function, or renal function. No adjustments to body weight-based rufinamide dosing in subjects ≥ 1 to < 4 years are necessary. Rufinamide was safe and well tolerated in these pediatric subjects. Results from the interim analysis demonstrate that rufinamide's safety and PK profile is comparable in subjects ≥ 1 to < 4 and ≥ 4 years with LGS. Study 303 (clinicaltrials.gov: NCT01405053).

Little is known about neuropsychological and social-cognitive function in patients with pediatric bipolar disorder. Identification of specific deficits and strengths that characterize pediatric bipolar disorder would facilitate advances in diagnosis, treatment, and research on pathophysiology. The purpose of this study was to test the hypothesis that youths with bipolar disorder would perform more poorly than matched healthy comparison subjects on measures of social cognition, motor inhibition, and response flexibility. Forty outpatients with pediatric bipolar disorder and 22 comparison subjects (no differences in age, gender, and IQ) completed measures of social cognition (the pragmatic judgment subtest of the Comprehensive Assessment of Spoken Language, facial expression recognition subtests of the Diagnostic Analysis of Nonverbal Accuracy Scale, the oral expression subtest of the Test of Language Competence), inhibition and response flexibility (stop and stop-change tasks), and motor inhibition (continuous performance tasks). Pediatric bipolar disorder patients performed more poorly than comparison subjects on social-cognitive measures (pragmatic judgment of language, facial expression recognition) and on a task requiring response flexibility. These deficits were present in euthymic patients. Differences between patients and comparison subjects could not be attributed to comorbid attention deficit hyperactivity disorder. Findings of impaired social cognition and response flexibility in youths with pediatric bipolar disorder suggest continuity between pediatric bipolar disorder and adult bipolar disorder. These findings provide a foundation for neurocognitive research designed to identify the neural mechanisms underlying these deficits.

The past few decades have seen increased scholarly attention to gay and lesbian individuals' aging experiences; however, few studies examine differences in subjective aging by sexual minority status. We identify four perspectives on the association between sexual minority status and subjective aging-double jeopardy, crisis competence, gender interactive, and limited salience perspectives. We examine each perspective's predictions using data from the first wave of Midlife in the United States (1995-1996; MIDUS). Ordinary least square regression models reveal strongest support for the limited salience perspective, suggesting that sexual minority status has weaker effects on subjective aging than do other social factors, such as age, health, and gender. However, some results provide support for the gender interactive perspective, positing that the effect of sexual minority status on subjective aging varies by gender. Our study provides an organizational framework of theoretical perspectives that can guide further examinations of variation in aging experiences by sexual minority status.

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.

Personality theory and research typically focus on chronological age as a key indicator of personality development. This study examines whether the subjective experience of age is an alternative marker of the biomedical and psychosocial factors that contribute to individual differences in personality development. The present study uses data from the Midlife in the United States longitudinal survey (N = 3,617) to examine how subjective age is associated with stability and change in personality and the dynamic associations between subjective age and personality traits over a 10-year period. Regression analyses indicated that a younger subjective age at baseline was associated with increases in Openness, Conscientiousness, and Agreeableness; correlated changes were also found. The rank-order stability of Extraversion and Openness and overall profile consistency were higher among those with a younger subjective age at baseline and were also associated with the rate of subjective aging over time. The present study reveals that beyond chronological age, the age an individual feels is related to changes in characteristic ways of thinking, feeling, and behaving over time. © 2014 Wiley Periodicals, Inc.

Background Survival rates in pediatric oncology have improved dramatically, in part due to high patient participation in clinical trials. Although racial/ethnic inequalities in clinical trial participation have been reported in adults, pediatric data and studies comparing participation rates by socio-demographic characteristics are scarce. The goal of this study was to assess differences in research protocol participation for childhood cancer by age, sex, race/ethnicity, parental language, cancer type and insurance status. Procedure Data on enrollment in any protocol, biospecimen, or therapeutic protocols were collected and analyzed for newly diagnosed pediatric patients with cancer from 2008–2012 at Rady Children’s Hospital. Results Among the 353 patients included in the analysis, 304 (86.1%) were enrolled in any protocol. Enrollment in biospecimen and therapeutic protocols was 84.2% (261/310) and 81.1% (206/254), respectively. Logistic regression analyses revealed significant enrollment underrepresentation in any protocol for Hispanics compared to Non-Hispanic whites (81% vs. 91%; Odds Ratio [OR], 0.43; 95% Confidence Interval [CI], 0.21–0.90; p=0.021) and among children of Spanish-speaking vs. English-speaking parents (78% vs. 89%; OR, 0.45; 95%CI, 0.23–0.87; p=0.016). Compared to patients aged 0–4 years, significant underrepresentation was also found among patients 15–21 years old (92% vs.72%; OR, 0.21; 95% CI, 0.09–0.48; p<0.001). Similar trends were observed when analyzing enrollment in biospecimen and therapeutic protocols separately. Conclusions There was significant underrepresentation in protocol participation for Hispanics, children of Spanish-speaking parents, and patients ages 15–21. Research is urgently needed to understand barriers to research participation among these groups underrepresented in pediatric oncology clinical trials. PMID:25755225

Morphometric magnetic resonance imaging (MRI) studies of pediatric bipolar disorder (BD) have not reported on gray matter volumes but have reported increased lateral ventricular size and presence of white matter hyperintensities (WMH). We studied gray matter volume, ventricular-to-brain ratios (VBR), and number of WMH in patients with familial, pediatric BD compared with control subjects. Twenty subjects with BD (aged 14.6 +/- 2.8 years; 4 female) according to the Washington University in St. Louis Kiddie Schedule for Affective Disorders and Schizophrenia, each with a parent with BD, and 20 age-, gender-, and intelligence quotient-matched healthy control subjects (aged 14.1 +/- 2.8 years; 4 female) were scanned at 3 T. Most subjects were taking psychotropic medications. A high-resolution T1-weighted spoiled gradient echo three-dimensional MRI sequence was analyzed by BrainImage for volumetric measurements, and T2-weighted images were read by a neuroradiologist to determine presence of WMH. After covarying for age and total brain volume, there were no significant differences between subjects with BD and control subjects in volume of cerebral (p = .09) or prefrontal gray matter (p = .34). Subjects with BD did not have elevated numbers of WMH or greater VBR when compared with control subjects. Children and adolescents with familial BD do not seem to have decreased cerebral grey matter or increased numbers of WMH, dissimilar to findings in adults with BD. Gray matter decreases and development of WMH might be later sequelae of BD or unique to adult-onset BD.

Subjective Age and Changes in Memory in Older Adults.

The subjective experience of aging, indexed by how old or young an individual feels, has been related to well-being and health-related outcomes among older adults. The present study examined whether subjective age is associated with memory level and changes, as indexed by measures of immediate and delayed recall. A complementary purpose was to test the mediating role of depressive symptoms and physical activity in the relation between subjective age and memory changes. Participants were drawn from three waves of the Health and Retirement Study. Subjective age, baseline memory measures, and covariates were assessed during the 2008 wave (N = 5809), depressive symptoms and physical activity were assessed again in the 2010 wave, and the follow-up memory measures were assessed in the 2012 wave. Regression analyses that included demographic, metabolic, and vascular covariates revealed that a younger subjective age at baseline was associated with better concurrent performance and with slower decline in immediate and delayed recall. Bootstrap procedures indicated that fewer depressive symptoms mediated these associations. Additional analyses revealed that memory level and change were unrelated to changes in subjective age. Beyond chronological age, the subjective experience of age is associated with cognitive aging. © The Author 2015.

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.

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

Objective To determine the association between family-centered rounds (FCR) and medical student knowledge acquisition as assessed by the National Board of Medical Examiners (NBME) pediatric subject (shelf) exam. Methods A retrospective cohort study was conducted of third-year medical students who graduated from Virginia Commonwealth University School of Medicine between 2009 and 2014. This timeframe represented the transition from 'traditional' rounds to FCR on the pediatric inpatient unit. Data collected included demographics, United States Medical Licensing Examination (USMLE) Step 1 and 2 scores, and NBME subject examinations in pediatrics (PSE), medicine (MSE), and surgery (SSE). Results Eight hundred and sixteen participants were included in the analysis. Student performance on the PSE could not be statistically differentiated from performance on the MSE for any year except 2011 (z-score=-0.17, p=0.02). Average scores on PSE for years 2009, 2010, 2013, and 2014 were significantly higher than for SSE, but not significantly different for all other years. The PSE was highly correlated with USMLE Step 1 and Step 2 examinations (correlation range 0.56-0.77) for all years. Conclusions Our results showed no difference in PSE performance during a time in which our institution transitioned to FCR. These findings should be reassuring for students, attending physicians, and medical educators.

Clinical research involves direct observation or data collection on human subjects. This study was conducted to evaluate the profile of pediatric neurology clinical research over a decade. Trends in pediatric neurology clinical research were documented through a systematic comparative review of articles published in selected journals. Eleven journals (five pediatric neurology, three general neurology, three general pediatrics) were systematically reviewed for articles involving a majority of human subjects less than 18 years of age for the years 1990 and 2000. Three hundred thirty-five clinical research articles in pediatric neurology were identified in the 11 journals for 1990 and 398 for 2000, a 19% increase. A statistically significant increase in analytic design (21.8% vs 39.5%; P = .01), statistical support (6% vs 16.6%; P < .0001), and multidisciplinary team (69.9% vs 87%; P = .003) was observed. In terms of specific study design, a significant decline in case reports (34.3% vs 10.3%; P < .0001) and an increase in case-control studies (11.3% vs 22.9%; P = .02) were evident over the 10-year interval. This comparative audit revealed that there has been a discernible change in the methodology profile of clinical research in child neurology over a decade. Trends apparently suggest a more rigorous approach to study design and investigation in this field.

In forensic practice, there is a growing need for accurate methods of age estimation, especially in the cases of young individuals of unknown age. Age can be estimated through somatic features that are universally considered associated with chronological age. Unfortunately, these features do not always coincide with the real chronological age: for these reasons that age determination is often very difficult. Our aim is to evaluate accuracy of skeletal age estimation using Tomei's MRI method in subjects between 12 and 19 years old for forensic purposes. Two investigators analyzed MRI images of the left hand and wrist of 77 male and 74 female caucasian subjects, without chronic diseases or developmental disorders, whose age ranged from 12 to 19 years. Skeletal maturation was determined by two operators, who analyzed all MRI images separately, in blinded fashion to the chronological age. Inter-rater agreement was measured with Pearson (R (2)) coefficient. One of the examiners repeated the evaluation after 6 months, and intraobserver variation was analyzed. Bland-Altman plots were used to determine mean differences between skeletal and chronological age. Inter-rater agreement Pearson coefficient showed a good linear correlation, respectively, 0.98 and 0.97 in males and females. Bland-Altman analysis demonstrated that the differences between chronological and skeletal age are not significant. Spearman's correlation coefficient showed good correlation between skeletal and chronological age both in females (R (2) = 0.96) and in males (R (2) = 0.94). Our results show that MRI skeletal age is a reproducible method and has good correlation with chronological age.

Children's health programs in Sub-Saharan Africa have always been oriented primarily to infectious diseases and malnutrition. We are witnessing in the early 21(st) century an epidemiological transition marked by the decline of old diseases and the identification of new diseases including heart disease. Therefore, it is necessary to describe the spectrum of these diseases in order to better prepare health workers to these new challenges. We conducted a cross-sectional study focused on heart disease diagnosed by echocardiography in children seen from January 2006 to December 2014 in a pediatric hospital of Yaounde. We collected socio-demographic data and the types of heart disease from registers, patients files as well as the electronic database of echocardiographic records. A total of 2,235 patients underwent echocardiographic examination during the study period including 1,666 subjects with heart disease. Congenital cardiopathies were found in 1,230 (73.8%) patients and acquired abnormalities in 429 (25.8%). Seven children (0.4%) had a combination of both types. Congenital heart defects (CHD) were dominated by ventricular septal defect (VSD). Acquired heart disease was mostly rheumatic valvulopathies. Dyspnea on exertion was the most frequent presenting complaint (87.6%). Discovery of a heart murmur was the principal clinical finding on physical examination (81.4%). The median age was 9 months for congenital heart disease and 132 months for acquired heart disease. As infectious diseases recede and the diagnostic facilities are improving, pediatric heart diseases occupy a more important position in the spectrum of pediatric diseases in our context. However, the ability to evoke the diagnosis remains unsatisfactory by the majority of health personnel and therefore needs to be improved. Apart from congenital heart diseases, the impact of acquired heart diseases, rheumatic valvulopathy being the highest ranking, is remarkable in pediatrics. Awareness of health

Restoring craniofacial symmetry is an important objective in the treatment of many craniofacial conditions. Normal form has been measured using anthropometry, cephalometry, and photography, yet all of these modalities have drawbacks. In this study, the authors define normal pediatric craniofacial form and craniofacial asymmetry using stereophotogrammetric images, which capture a densely sampled set of points on the form. After institutional review board approval, normal, healthy children (n = 533) with no known craniofacial abnormalities were recruited at well-child visits to undergo full head stereophotogrammetric imaging. The children's ages ranged from 0 to 18 years. A symmetric three-dimensional template was registered and scaled to each individual scan using 25 manually placed landmarks. The template was deformed to each subject's three-dimensional scan using a thin-plate spline algorithm and closest point matching. Age-based normal facial models were derived. Mean facial asymmetry and statistical characteristics of the population were calculated. The mean head asymmetry across all pediatric subjects was 1.5 ± 0.5 mm (range, 0.46 to 4.78 mm), and the mean facial asymmetry was 1.2 ± 0.6 mm (range, 0.4 to 5.4 mm). There were no significant differences in the mean head or facial asymmetry with age, sex, or race. Understanding the "normal" form and baseline distribution of asymmetry is an important anthropomorphic foundation. The authors present a method to quantify normal craniofacial form and baseline asymmetry in a large pediatric sample. The authors found that the normal pediatric craniofacial form is asymmetric, and does not change in magnitude with age, sex, or race.

Chordomas are rare malignancies that primarily affect adults, but also rarely affect pediatric patients. We compared the imaging appearance, demographic and anatomic distributions of adult and pediatric chordomas in a large cohort. We performed a retrospective review of medical records of 220 subjects with histologically confirmed chordomas of the axial skeleton and pre-treatment magnetic resonance imaging studies. Age, sex, type of chordoma (conventional, chondroid or dedifferentiated), the anatomic location of the chordoma, as well as whether the lesion was primarily extra-osseous were recorded. Pediatric subjects were less than 21 years at the time of diagnosis. Binomial two-sample tests of proportions and Fisher's exact tests were used to compare proportions between the pediatric and adult subjects. Fifty six pediatric subjects (58.9 % female) and 164 adult subjects (42.1 % female) were identified. The proportion of female subjects with chordomas was significantly higher in the pediatric cohort compared to the adult cohort (P = 0.04). Most chordomas occur in Caucasians, however African-Americans were more represented in the pediatric cohort than in the adult cohort (P = 0.01). 69.6 % (39/56) of the pediatric chordomas involved the clivus/skull base and cervical spine compared to 29.3 % (48/164) of the adult chordomas (P = 1.99 × 10(-7)). Only 1.8 % (1/56) of the pediatric chordomas was in the sacrococcygeal region compared to 36.0 % (59/164) of the adult chordomas (P = 2.55 × 10(-8)). In cases where pre-treatment imaging was available, 93.8 % (16/17) of pediatric chordomas were predominantly extra-osseous compared to 76.7 % (46/60) of adult chordomas (P = 0.17). Pediatric chordomas more often affect females and occur most frequently at the craniocervical junction with decrease in incidence distally in the spine, whereas adult chordomas most frequently involve the craniocervical and sacrococcygeal regions.

We compared uropathogen antibiotic susceptibility across age groups of ambulatory pediatric patients. For Escherichia coli (n=5,099) and other Gram-negative rods (n=626), significant differences (p<0.05) existed across age groups for ampicillin, cefazolin, and trimethoprim/sulfamethoxazole susceptibility. In E. coli, differences in trimethoprim/sulfamethoxazole susceptibility varied from 79% in children under 2 to 88% in ages 16–18 (p<0.001) while ampicillin susceptibility varied from 30% in children under 2 to 53% in ages 2–5 (p=0.015). Uropathogen susceptibility to common urinary anti-infectives may be lower in the youngest children. Further investigation into these differences is needed to facilitate appropriate and prudent treatment of urinary tract infections. PMID:24091131

Animal models and studies in adults have demonstrated that copper restriction increases severity of liver injury in nonalcoholic fatty liver disease (NAFLD). This has not been studied in children. We aimed to determine if lower tissue copper is associated with increased NAFLD severity in children. This was a retrospective study of pediatric patients who had a liver biopsy including a hepatic copper quantitation. The primary outcome compared hepatic copper concentration in NAFLD versus non-NAFLD. Secondary outcomes compared hepatic copper levels against steatosis, fibrosis, lobular inflammation, balloon degeneration, and NAFLD activity score (NAS). The study analysis included 150 pediatric subjects (102 with NAFLD and 48 non-NAFLD). After adjusting for age, body mass index z score, gamma glutamyl transferase, alanine aminotransferase, and total bilirubin, NAFLD subjects had lower levels of hepatic copper than non-NAFLD (P = 0.005). In addition, tissue copper concentration decreased as steatosis severity increased (P < 0.001). Copper levels were not associated with degree of fibrosis, lobular inflammation, portal inflammation, or balloon degeneration. In this cohort of pediatric subjects with NAFLD, we observed decreased tissue copper levels in subjects with NAFLD when compared with non-NAFLD subjects. In addition, tissue copper levels were lower in subjects with nonalcoholic steatohepatitis, a more severe form of the disease, when compared with steatosis alone. Further studies are needed to explore the relationship between copper levels and NAFLD progression.

Pediatric thyroid cancer (TC) is rare but its incidence is increasing. We analyzed incidence and characteristics of pediatric TC in Sicily and comparatively evaluated data from the volcanic and non-volcanic areas. All incident pediatric (0-19 years) TCs in Sicily between 2002-2009 were analyzed for the area of residence and compared to data for adults. A total of 54 differentiated TCs (DTC) and nine medullary TCs were diagnosed in Sicily in children between 2002-2009. DTC age standardized rate for the world population (ASRw) was 0.8/10 5 in females and 0.2/10 5 in males, with a higher incidence in the volcanic area (ASRw=1.4/10 5 in females, 0.5/10 5 in males) vs. the rest of Sicily (ASRw=0.6/10 5 in females, 0.1/10 5 in males). Pediatric TCs were larger in size and more frequently with extrathyroid extension and lymph-node involvement in comparison to TCs in adults. In the volcanic environment of Sicily, TC incidence is markedly increased in children, suggesting a short-term effect of unidentified carcinogens of volcanic origin.

Pediatric unintentional falls are the leading cause of injury-related emergency visits for children < 5 years old. The purpose of this study was to identify population characteristics, injury mechanisms, and injury severities and patterns among children < 5 years to better inform age-appropriate falls prevention strategies. This retrospective database study used trauma registry data from the lead pediatric trauma system in Georgia. Data were analyzed for all patients < 5 years with an international classification of disease, 9th revision, clinical modification (ICD-9 CM) external cause of injury code (E-code) for unintentional falls between 1/1/2013 and 12/31/2015. Age (months) was compared across categories of demographic variables, injury mechanisms, and emergency department (ED) disposition using Kruskal-Wallis ANOVA and the Mann Whitney U test. The relationships between demographic variables, mechanism of injury (MOI), and Injury Severity Score (ISS) were evaluated using multinomial logistic regression. Inclusion criteria were met by 1086 patients (median age = 28 months; 59.7% male; 53.8% White; 49.1% <  1 m fall height). Younger children, < 1-year-old, primarily fell from caregiver's arms, bed, or furniture, while older children sustained more falls from furniture and playgrounds. Children who fell from playground equipment were older (median = 49 months, p < 0.01) than those who fell from the bed (median = 10 months), stairs (median = 18 months), or furniture (median = 19 months). Children < 1 year had the highest proportion of head injuries including skull fracture (63.1%) and intracranial hemorrhage (65.5%), 2-year-old children had the highest proportion of femur fractures (32.9%), and 4-year-old children had the highest proportion of humerus fractures (41.0%). Medicaid patients were younger (median = 24.5 months, p < 0.01) than private payer (median = 34 months). Black patients were younger

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

Although discouraged, pacifier usage is widespread and often practiced beyond two years of age. The current study explored the effects of maternal education and dental visits on the age of pacifier withdrawal. The dental histories of 213 children (53.1% male) attending a primary school in Madrid were obtained along with maternal education level and age at pacifier withdrawal. Data were analyzed by using independent samples t-test, one-way ANOVA two-way ANOVA and a complementary non-parametric approach was also used. There was a significant effect of maternal education on the age of pacifier withdrawal; the higher the maternal education, the younger the age of withdrawal. The frequency of dental visits influenced the relationship between maternal education and the age of pacifier withdrawal. Dental visits considerably shortened pacifier use among children with low- and medium-educated mothers. Pediatric dentists play a critical role in the correction of unhealthy oral habits such as prolonged pacifier use. The educational component of pediatric dentistry could reverse the lack of knowledge or misinformation among high-risk groups (e.g. low maternal education). As a consequence, we recommend that children start dental visits at an early age and maintain visits with a high frequency.

Current guidelines adopted by the American Academy of Pediatrics calls for prolonged fasting times before performing pediatric procedural sedation and analgesia (PSA). PSA is increasingly provided to children outside of the operating theater by sedation trained pediatric providers and does not require airway manipulation. We investigated the safety of a shorter fasting time compared to a longer and guideline compliant fasting time. We tried to identify the association between fasting time and sedation-related complications. This is a prospective observational study that included children 2 months to 18 years of age and had an American Society of Anesthesiologists physical status classification of I or II, who underwent deep sedation for elective procedures, performed by pediatric critical care providers. Procedures included radiologic imaging studies, electroencephalograms, auditory brainstem response, echocardiograms, Botox injections, and other minor surgical procedures. Subjects were divided into two groups depending on the length of their fasting time (4-6 h and >6 h). Complication rates were calculated and compared between the three groups. In the studied group of 2487 subjects, 1007 (40.5%) had fasting time of 4-6 h and the remaining 1480 (59.5%) subjects had fasted for >6 h. There were no statistically significant differences in any of the studied complications between the two groups. This study found no difference in complication rate in regard to the fasting time among our subjects cohort, which included only healthy children receiving elective procedures performed by sedation trained pediatric critical care providers. This suggests that using shorter fasting time may be safe for procedures performed outside of the operating theater that does not involve high-risk patients or airway manipulation.

Adult patient series have shown hand-held echocardiography (echo) units (HHE) to be accurate for rapid diagnosis and triage. This is the first study to evaluate the ability of HHE to inform decision making in outpatient pediatric cardiology. New pediatric cardiology patients in outpatient clinics staffed by six pediatric cardiologists (experience 1-17 years) were prospectively enrolled if an echocardiogram (echo) was ordered during their initial visit. After history and physical examination and before a standard echo, the cardiologists performed a bedside HHE examination (GE Vscan 1.7-3.8 MHz), documented findings, and made a clinical decision. Diagnoses and decisions based on HHE were compared with final management after the standard echo. The study enrolled 101 subjects (ages 9 days to 19 years). The cardiologists considered HHE imaging adequate for decision making for 80 of the 101 subjects. For 77 of the 80 subjects with acceptable HHE imaging (68/68 normal and 9/12 abnormal standard echoes), the HHE-based primary diagnoses and decisions agreed with the final management. The sensitivity of HHE was 75 % (95 % confidence interval [CI] 43-94 %) and the positive predictive value 100 % (95 % CI 66-100 %) for pediatric heart disease. The agreement between standard echocardiography and HHE imaging was substantial (κ = 0.82). Excluding one of the least experienced cardiologists, HHE provided the basis for correct cardiac diagnoses and management for all the subjects with acceptable HHE imaging (58/58 normal and 9/9 abnormal echoes). In outpatient pediatric cardiology, HHE has potential as a tool to complement physical examination. Further investigation is needed to evaluate how value improves with clinical experience.

The effectiveness of high-frequency oscillatory ventilation (HFOV) in the pediatric hematopoietic cell transplant patient has not been established. We sought to identify current practice patterns of HFOV, investigate parameters during HFOV and their association with mortality, and compare the use of HFOV to conventional mechanical ventilation in severe pediatric ARDS. This is a retrospective analysis of a multi-center database of pediatric and young adult allogeneic hematopoietic cell transplant subjects requiring invasive mechanical ventilation for critical illness from 2009 through 2014. Twelve United States pediatric centers contributed data. Continuous variables were compared using a Wilcoxon rank-sum test or a Kruskal-Wallis analysis. For categorical variables, univariate analysis with logistic regression was performed. The database contains 222 patients, of which 85 subjects were managed with HFOV. Of this HFOV cohort, the overall pediatric ICU survival was 23.5% ( n = 20). HFOV survivors were transitioned to HFOV at a lower oxygenation index than nonsurvivors (25.6, interquartile range 21.1-36.8, vs 37.2, interquartile range 26.5-52.2, P = .046). Survivors were transitioned to HFOV earlier in the course of mechanical ventilation, (day 0 vs day 2, P = .002). No subject survived who was transitioned to HFOV after 1 week of invasive mechanical ventilation. We compared subjects with severe pediatric ARDS treated only with conventional mechanical ventilation versus early HFOV (within 2 d of invasive mechanical ventilation) versus late HFOV. There was a trend toward difference in survival (conventional mechanical ventilation 24%, early HFOV 30%, and late HFOV 9%, P = .08). In this large database of pediatric allogeneic hematopoietic cell transplant subjects who had acute respiratory failure requiring invasive mechanical ventilation for critical illness with severe pediatric ARDS, early use of HFOV was associated with improved survival compared to late

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

Pediatric obesity has become a significant public health concern. The historical focus in pediatric liver transplant (LT) has been undernutrition, with limited knowledge regarding obesity. Therefore, we sought to determine the prevalence of obesity in pediatric LT, compare it to National Health and Nutrition Examination Surveys (NHANES) data, and identify risk factors for obesity in pediatric LT. SPLIT, which collects pediatric LT data at 39 centers, was queried for subjects ages 2 to 18 years at follow-up, LT between 1995 and 2007, and with at least 1 body mass index measured 1 to 5 years after LT. Of 1706 individuals included, 44% had biliary atresia (47% boys, 58% white, mean age at LT 4.6 years). Of these individuals, 19% were obese at 1 year and 18% at 3 years, higher than in the general pediatric population reported by 2003-2004 NHANES, whereas 11% obesity at 5 years after LT was similar to NHANES data. Using logistic regression, Hispanic ethnicity (odds ratio [OR] 1.8, 95% confidence interval [CI] 1.19-2.23), steroid use at follow-up (OR 1.48, 95% CI 1.23-1.77), overweight (OR 4.34, 95% CI 2.91-6.68), and obesity (OR 10.62, 95% CI 5.9-19.65) at LT independently predicted post-LT obesity. These findings suggest a need to broaden standard care to include obesity assessment and intervention in routine pre- and posttransplant care.

Pediatric bipolar disorder is a severe and impairing illness. Characterizing the impact of pediatric bipolar disorder on cognitive function might aid in understanding the phenomenology of the disorder. While previous studies of pediatric bipolar disorder have reported deficits in cognitive control and reward behavior, little is understood about how affective processes influence behavioral control. Relative to prior studies using manual-response paradigms, eye movement tasks provide a more precise assessment of reward sensitivity and cognitive and motor control. The current study compares 20 youths with bipolar disorder (mean age = 13.9 years ± 2.22) and 23 healthy subjects (mean age = 13.8 years ± 2.49) on a mixed pro–antisaccade task with monetary incentives. On both types of saccades, participants were presented with three types of incentives: those where subjects can win money, lose money, or neither win nor lose money. Impaired reward processing was found in youths with bipolar disorder relative to controls, particularly on antisaccades. This difference was reflected in lower error rates during incentive trials in the control but not in the bipolar disorder group. By comparison, no group differences were found on prosaccade trials. The results provide further evidence for deficits in cognitive and reward processing in bipolar disorder. PMID:20080923

Characterization of the age-dependent shape of the pediatric thoracic spine and vertebrae using generalized procrustes analysis.

Generalized Procrustes Analysis (GPA) is a superimposition method used to generate size-invariant distributions of homologous landmark points. Several studies have used GPA to assess the three-dimensional (3D) shapes of or to evaluate sex-related differences in the human brain, skull, rib cage, pelvis and lower limbs. Previous studies of the pediatric thoracic vertebrae suggest that they may undergo changes in shape asa result of normative growth. This study uses GPA and second order polynomial equations to model growth and age- and sex-related changes in shape of the pediatric thoracic spine. We present a thorough analysis of the normative 3D shape, size, and orientation of the pediatric thoracic spine and vertebrae as well as equations which can be used to generate models of the thoracic spine and vertebrae for any age between 1 and 19years. Such models could be used to create more accurate 3D reconstructions of the thoracic spine, generate improved age-specific geometries for finite element models (FEMs) and used to assist clinicians with patient-specific planning and surgical interventions for spine deformity.

Eisen, Marc D; Franck, Kevin H

2004-12-01

To characterize the amplitude growth functions of the electrically evoked compound action potential (ECAP) in pediatric subjects implanted with the Clarion HiFocus electrode array with respect to electrode position and the presence or absence of a Silastic positioner. Electrophysiologic growth function data are compared with HiResolution (HiRes) psychophysical programming levels. ECAP growth functions were measured for all electrodes along the implant's array in 16 pediatric subjects. Nine of the patients were implanted with a Silastic positioner, whereas seven had no positioner. ECAP thresholds and growth function slopes were calculated. Fifteen of the 16 patients had psychophysical threshold and maximum comfort levels available. Programming levels and ECAP thresholds were compared within and among the subjects. ECAP thresholds showed variability among patients, ranging from 178 to 920 nA at 32 musec pulse width. ECAP thresholds did not depend on electrode position along the cochlea but were lower in the presence of the Silastic positioner (p < 0.001). Thresholds determined with the masker-probe versus the alternating polarity paradigms revealed moderate (r = 0.76) correlation. Growth function slopes also showed considerable variation among patients. Unlike thresholds, slopes decreased from apical to basal cochlear locations (p < 0.001) but showed no difference between the absence and presence of the positioner. Programming levels in HiRes were correlated with ECAP threshold levels. When ECAP thresholds were adjusted for each patient by the difference between M level and ECAP threshold at electrode 9, however, overall correlation between the two measurements was excellent (r = 0.98, N = 224). In pediatric subjects with the Clarion HiFocus electrode, ECAP growth function thresholds appear to decrease with the presence of the Silastic positioner but are unaffected by electrode position along the array. Growth function slope, however, depends on electrode position

Smaller amygdalar volumes have been consistently observed in pediatric bipolar disorder subjects compared to healthy control subjects. Whether smaller amygdalar volume is a consequence or antecedent of the first episode of mania is not known. Additionally, smaller volume has not been localized to specific amygdala subregions. We compared surface contour maps of the amygdala between 22 youths at high risk for bipolar disorder, 26 youths meeting full diagnostic criteria for pediatric familial bipolar disorder, and 24 healthy control subjects matched for age, gender, and intelligence quotient. Amygdalae were manually delineated on three-dimensional spoiled gradient echo images by a blinded rater using established tracing protocols. Statistical surface mesh modeling algorithms supported by permutation statistics were used to identify regional surface differences between the groups. When compared to high-risk subjects and controls, youth with bipolar disorder showed surface deformations in specific amygdalar subregions, suggesting smaller volume of the basolateral nuclei. The high-risk subjects did not differ from controls in any subregion. These findings support previous reports of smaller amygdala volume in pediatric bipolar disorder and map the location of abnormality to specific amygdala subregions. These subregions have been associated with fear conditioning and emotion-enhanced memory. The absence of amygdala size abnormalities in youth at high risk for bipolar disorder suggests that reductions might occur after the onset of mania. © 2013 John Wiley & Sons A/S.

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.

Objective This manuscript provides an evidence-based psychometric review of parent and child-report pediatric sleep measures using criteria developed by the American Psychological Association (APA) Division 54 Evidence-Based Assessment (EBA) Task Force. Methods Twenty-one measures were reviewed: four measures of daytime sleepiness, four measures of sleep habits/hygiene, two measures assessing sleep-related attitudes/cognitions, five measures of sleep initiation/maintenance, and six multidimensional sleep measures. Results Six of the 21 measures met “well-established” evidence-based assessment criteria. An additional eight measures were rated as “approaching well-established” and seven were rated as “promising.” Conclusions Overall, the multidimensional sleep measures received the highest ratings. Strengths and weaknesses of the measures are described. Recommendations for future pediatric sleep assessment are presented including further validation of measures, use of multiple informants, and stability of sleep measures over time. PMID:21227912

It has been observed that subjective age (SA) often trails chronological age, especially in older adults. In a previously published article, we argued that differences in individual's SA is a function of their level of activity on biological, mental, and social dimensions. This article empirically tests this proposition using a newly created Subjective Aging Index (SAI). The SAI is related to SA above the effect of age with differences existing across age groups and sex. The findings contribute to the literature on successful aging strategies with important implications for health care practitioners, marketers, and individuals heading towards older adult years.

Background Pediatric sudden cardiac arrest (CA) is an unfortunate and devastating condition, often leading to poor neurologic outcomes. However, little experimental data on the pathophysiology of pediatric CA is currently available due to the scarcity of animal models. New Method We developed a novel experimental model of pediatric cardiac arrest and cardiopulmonary resuscitation (CA/CPR) using postnatal day 20–25 mice. Adult (8–12 weeks) and pediatric (P20–25) mice were subjected to 6 min CA/CPR. Hippocampal CA1 and striatal neuronal injury were quantified 3 days after resuscitation by hematoxylin and eosin (H&E) and Fluoro-Jade B staining, respectively. Results Pediatric mice exhibited less neuronal injury in both CA1 hippocampal and striatal neurons compared to adult mice. Increasing ischemia time to 8 min CA/CPR resulted in an increase in hippocampal injury in pediatric mice, resulting in similar damage in adult and pediatric brains. In contrast, striatal injury in the pediatric brain following 6 or 8 min CA/CPR remained extremely low. As observed in adult mice, cardiac arrest causes delayed neuronal death in pediatric mice, with hippocampal CA1 neuronal damage maturing at 72 hours after insult. Finally, mild therapeutic hypothermia reduced hippocampal CA1 neuronal injury after pediatric CA/CPR. Comparison with Existing Method This is the first report of a cardiac arrest and CPR model of global cerebral ischemia in mice Conclusions Therefore, the mouse pediatric CA/CPR model we developed is unique and will provide an important new tool to the research community for the study of pediatric brain injury.

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.

Perceiving oneself as younger than one's actual age functions as a self-enhancing positive illusion that promotes life satisfaction. However, no research has yet focused on the mechanisms through which a youthful subjective age could be related to higher life satisfaction. The purpose of this study was to identify the mediating role of resources, such as subjective health and memory self-efficacy, in the relation between subjective age and life satisfaction among older adults. A cross-sectional study was conducted with 250 older individuals aged from 60 to 77 years who completed measures of subjective age, subjective health, memory self-efficacy, and life satisfaction. Path analysis revealed that subjective age was positively related to both subjective health and memory self-efficacy, and that subjective health and memory self-efficacy were both positively related to life satisfaction. Bootstrap procedures further indicated that subjective age has significant total and specific indirect contribution to life satisfaction through subjective health and memory self-efficacy. This study fills a gap in existing literature and suggests that a youthful subjective age is associated with higher life satisfaction because it is related to higher evaluation of health and memory self-efficacy. It provides an initial support for a resource-based explanation of the relation between subjective age and life satisfaction.

Inventory of pediatric neurology "manpower" in Canada.

Keene, Daniel L; Humphreys, Peter

2005-08-01

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.

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.

Although caregiver burden is relevant to the outcome for psychiatrically ill youth, most studies have focused on caregiver burden in the community or research settings. Therefore, we aimed at evaluating the subjective caregiver strain (SCS) at the time of presentation of youth to a pediatric psychiatric emergency room (PPER), assessing potential correlates to provide leads for improvements in formal support systems. In this retrospective cohort study, the internalized, externalized, and total SCS were assessed in caregivers of youth <18 years of age consecutively evaluated at a PPER during a 1 year period using the Caregiver Strain Questionnaire. Sociodemographic and a broad range of clinical data were collected during the PPER visit using a 12-page semistructured institutional evaluation form. The Appropriateness of Pediatric Psychiatric Emergency Room Contact scale, incorporating acuity, severity and harm potential, was used to rate appropriateness of the visit. In caregivers of 444 youth, the internalized SCS was significantly higher than the externalized SCS (p < 0.001). Multivariable analyses indicated that higher total and externalized SCS were associated with disruptive behavior or substance abuse/dependent disorder diagnosis, presenting complaint of aggression, and discharge plan to the police. Higher total and internalized SCS were associated with lower child functioning, whereas total and internalized SCS were lower in adopted children. In addition, higher externalized SCS was associated with investigator-rated inappropriateness of the emergency visit, presenting complaint of defiance, and a lack of prior psychiatric ER visits. High levels of CS in PPER highlight the necessity to adhere to existing guidelines regarding the inclusion of caregivers' perceptions into comprehensive psychiatric assessments. The particularly high strain in caregivers of children with externalizing disorders and in families with low-functioning youth may need to prompt PPER

Acetaminophen toxicity is a common cause of pediatric liver failure. The diagnosis may be limited by the short window of detection of acetaminophen in serum. Recently acetaminophen protein adducts (APAP-CYS) have been used as a biomarker with a longer duration of detection. The objective of this study was to describe the serum concentrations of APAP-CYS in pediatric patients with and without reported therapeutic acetaminophen exposure. A cross-sectional study of children age 1 to <12 years presenting to a pediatric emergency department. Subjects were stratified by recent acetaminophen use and had serum APAP-CYS measured using LC/MS. One hundred patients were enrolled. All of the patients whose caregivers denied acetaminophen exposure had nondetectable APAP-CYS. Fifty-two percent of subjects who were reported to have taken acetaminophen in the preceding 2 weeks had detectable serum APAP-CYS. The APAP-CYS concentrations were positively correlated with higher overall dose and more recent ingestion. APAP-CYS is detectable in the majority of children taking acetaminophen and not detected in the majority of children who are not exposed to acetaminophen.

Abstract: Pediatric Bipolar Disorder (BD) is a highly morbid pediatric psychiatric disease, consistently associated with family psychiatric history of mood disorders and associated with high levels of morbidity and disability and with a great risk of suicide. While there is a general consensus on the symptomatology of depression in childhood, the phenomenology of pediatric mania is still highly debated and the course and long-term outcome of pediatric BD still need to be clarified. We reviewed the available studies on the phenomenology of pediatric mania with the aim of summarizing the prevalence, demographics, clinical correlates and course of these two types of pediatric mania. Eighteen studies reported the number of subjects presenting with either irritable or elated mood during mania. Irritability has been reported to be the most frequent clinical feature of pediatric mania reaching a sensitivity of 95–100% in several samples. Only half the studies reviewed reported on number of episodes or cycling patterns and the described course was mostly chronic and ultra-rapid whereas the classical episodic presentation was less common. Few long-term outcome studies have reported a diagnostic stability of mania from childhood to young adult age. Future research should focus on the heterogeneity of irritability aiming at differentiating distinct subtypes of pediatric psychiatric disorders with distinct phenomenology, course, outcome and biomarkers. Longitudinal studies of samples attending to mood presentation, irritable versus elated, and course, chronic versus episodic, may help clarify whether these are meaningful distinctions in the course, treatment and outcome of pediatric onset bipolar disorder.

Pediatric maxillofacial fractures.

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.

Personality, self-rated health, and subjective age in a life-span sample: the moderating role of chronological age.

The present study tested whether chronological age moderates the association between subjective age and self-rated health and personality in a community-dwelling life-span sample (N = 1,016; age range: 18-91 years). Self-rated health, extraversion, and openness to experience were associated with a younger subjective age at older ages. Conscientious individuals felt more mature early in life. Conscientiousness, neuroticism, and agreeableness were not related to subjective age at older ages. These findings suggest that with aging self-rated health and personality traits are increasingly important for subjective age. 2013 APA, all rights reserved

The reintroduction of measles-rubella combined (MR) vaccination to Japan raised concerns about adverse events as well as immunogenicity related to booster immunization in subjects with naturally acquired immunity to measles or rubella. The time course of reactogenicity and antibody responses in recipients with pre-existing immunity to measles through natural infection was observed. Eighteen children aged 80-104 months received MR booster vaccination; 16 of them had had previous rubella vaccination. There were virtually no clinical reactions related to booster vaccination, and a highly significant antibody response to rubella antigen, whereas the antibody rise to measles was statistically significant but poor. Vaccination of individuals already immune is not harmful. Booster immunization to rubella for Japanese children is vitally important. © 2015 Japan Pediatric Society.

Dose selection is one of the key decisions made during drug development in pediatrics. There are regulatory initiatives that promote the use of model-based drug development in pediatrics. Pharmacometrics or quantitative clinical pharmacology enables development of models that can describe factors affecting pharmacokinetics and/or pharmacodynamics in pediatric patients. This manuscript describes some examples in which pharmacometric analysis was used to support approval and labeling in pediatrics. In particular, the role of pharmacokinetic (PK) comparison of pediatric PK to adults and utilization of dose/exposure-response analysis for dose selection are highlighted. Dose selection for esomeprazole in pediatrics was based on PK matching to adults, whereas for adalimumab, exposure-response, PK, efficacy, and safety data together were useful to recommend doses for pediatric Crohn's disease. For vigabatrin, demonstration of similar dose-response between pediatrics and adults allowed for selection of a pediatric dose. Based on model-based pharmacokinetic simulations and safety data from darunavir pediatric clinical studies with a twice-daily regimen, different once-daily dosing regimens for treatment-naïve human immunodeficiency virus 1-infected pediatric subjects 3 to <12 years of age were evaluated. The role of physiologically based pharmacokinetic modeling (PBPK) in predicting pediatric PK is rapidly evolving. However, regulatory review experiences and an understanding of the state of science indicate that there is a lack of established predictive performance of PBPK in pediatric PK prediction. Moving forward, pharmacometrics will continue to play a key role in pediatric drug development contributing toward decisions pertaining to dose selection, trial designs, and assessing disease similarity to adults to support extrapolation of efficacy.

Greenham, Mardee; Anderson, Vicki; Mackay, Mark T

2017-04-01

The past 20 years have seen a 35% increase in prevalence of pediatric stroke. Contrary to widely held views, children do not recover better than adults. This review explores the impact of pediatric stroke on cognitive domains, including intellectual and executive functions, memory and behavior, and the influence of age, lesion characteristics, and comorbidities on outcome. Cognitive problems occur in up to half of ischemic and hemorrhagic stroke survivors. Single-center studies have shown intelligence quotient scores skewed to the lower end of the average range, with greater impairment in performance than verbal domains. Executive function, such as attention and processing speed are particularly vulnerable to the effects of pediatric stroke. Age at stroke, larger infarct size, cortical/subcortical lesion location, epilepsy, and comorbid physical deficits are associated with poorer cognitive outcomes. Cognitive impairment occurs relatively frequently following pediatric stroke but the nature, severity, and predictors of specific deficits are not well defined. Improving understanding of outcomes following pediatric stroke is a key priority for families but a paucity of data limits the ability to develop targeted disease, and age-specific pediatric rehabilitation strategies to optimize cognitive outcomes following pediatric stroke.

Purpose To examine anthropometric and maturational characteristics at diagnosis in pediatric idiopathic intracranial hypertension (IIH). Design Retrospective, international, multisite study. Participants Pediatric patients (2–18 years of age at diagnosis) with IIH. Main Outcome Measures Body mass index (BMI), height, and weight Z-scores; sexual maturation. 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

Background and Objectives To evaluate the relationship between age and anesthesia method used for tympanostomy tube insertion (TTI) and to provide evidence to guide the selection of an appropriate anesthesia method in children. Subjects and Methods We performed a retrospective review of children under 15 years of age who underwent tympanostomy tube insertion (n=159) or myringotomy alone (n=175) under local or general anesthesia by a single surgeon at a university-based, secondary care referral hospital. Epidermiologic data between local and general anesthesia groups as well as between TTI and myringotomy were analyzed. Medical costs were compared between local and general anesthesia groups. Results Children who received local anesthesia were significantly older than those who received general anesthesia. Unilateral tympanostomy tube insertion was performed more frequently under local anesthesia than bilateral. Logistic regression modeling showed that local anesthesia was more frequently applied in older children (odds ratio=1.041) and for unilateral tympanostomy tube insertion (odds ratio=8.990). The cut-off value of age for local anesthesia was roughly 5 years. Conclusions In a pediatric population at a single medical center, age and whether unilateral or bilateral procedures were required were important factors in selecting an anesthesia method for tympanostomy tube insertion. Our findings suggest that local anesthesia can be preferentially considered for children 5 years of age or older, especially in those with unilateral otitis media with effusion. PMID:26185791

The effect of cognitive testing and feedback on older adults' subjective age.

Subjective age, or how old a person feels, is an important measure of self-perception that is associated with consequential cognitive and health outcomes. Recent research suggests that subjective age is affected by certain situations, including cognitive testing contexts. The current study examined whether cognitive testing and positive performance feedback affect subjective age and subsequent cognitive performance. Older adults took a series of neuropsychological and cognitive tests and subjective age was measured at various time points. Participants also either received positive or no feedback on an initial cognitive task, an analogies task. Results showed that participants felt older over the course of the testing session, particularly after taking a working memory test, relative to baseline. Positive feedback did not significantly mitigate this subjective aging effect. Results suggest that subjective age is malleable and that it can be affected by standard cognitive and neuropsychological test conditions.

To determine if nephrolithiasis-associated atherosclerosis has pediatric origins and to consider possible association between kidney stones and atherosclerosis-related proteins. We matched children aged 12-17 years with kidney stones and without kidney stones. Carotid artery intima-media thickness (cIMT) was measured by ultrasound. Participants' urine was investigated by enzyme-linked immunosorbent assay for the atherosclerosis-related proteins fibronectin 1, macrophage scavenger receptor 1, osteopontin, and vascular cell adhesion molecule 1 levels, and normalized to urine creatinine levels. Subjects with nephrolithiasis had higher cIMT in the right common carotid artery and overall mean measurement. Urine osteopontin and fibronectin 1 were significant predictors of cIMT. We have provided initial preliminary evidence that nephrolithiasis-associated atherosclerosis has pediatric origins and performed studies that begin to identify potential reasons for the association of nephrolithiasis and vascular disease.

To determine cancer incidence in a large pediatric-onset systemic lupus erythematosus (SLE) population. Data were examined from 12 pediatric SLE registries in North America. Patients were linked to their regional cancer registries to detect cancers observed after cohort entry, defined as date first seen in the clinic. The expected number of malignancies was obtained by multiplying the person-years in the cohort (defined from cohort entry to end of followup) by the geographically matched age-, sex-, and calendar year-specific cancer rates. The standardized incidence ratio (SIR; ratio of cancers observed to expected) was generated, with 95% CI. A total of 1168 patients were identified from the registries. The mean age at cohort entry was 13 years (SD 3.3), and 83.7% of the subjects were female. The mean duration of followup was 7.6 years, resulting in a total observation period of 8839 years spanning the calendar period 1974-2009. During followup, fourteen invasive cancers occurred (1.6 cancers per 1000 person-yrs, SIR 4.13, 95% CI 2.26-6.93). Three of these were hematologic (all lymphomas), resulting in an SIR for hematologic cancers of 4.68 (95% CI 0.96-13.67). SIR were increased for both male and female patients, and across age groups. Although cancer remains a relatively rare outcome in pediatric-onset SLE, our data do suggest an increase in cancer for patients followed an average of 7.6 years. About one-fifth of the cancers were hematologic. Longer followup, and study of drug effects and disease activity, is warranted.

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.

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.

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

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.

Kinematics is recommended for the quantitative assessment of upper limb movements. The aims of this study were to determine the age effects on upper limb kinematics and establish normative values in healthy subjects. Three hundred and seventy healthy subjects, aged 3-93 years, participated in the study. They performed two unidirectional and two geometrical tasks ten consecutive times with the REAplan, a distal effector robotic device that allows upper limb displacements in the horizontal plane. Twenty-six kinematic indices were computed for the four tasks. For the four tasks, nineteen of the computed kinematic indices showed an age effect. Seventeen indices (the accuracy, speed and smoothness indices and the reproducibility of the accuracy, speed and smoothness) improved in young subjects aged 3-30 years, showed stabilization in adults aged 30-60 years and declined in elderly subjects aged 60-93 years. Additionally, for both geometrical tasks, the speed index exhibited a decrease throughout life. Finally, a principal component analysis provided the relations between the kinematic indices, tasks and subjects' age. This study is the first to assess age effects on upper limb kinematics and establish normative values in subjects aged 3-93 years.

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.

The aim of this study was to discern the percentile distribution of the Active Substance Index (AKS) in boys and girls aged 4 to 9 years in order to obtain reference values for this indicator. This index was calculated in 3634 healthy and well-nourished children with normal stature from a poor urban community at Centro de Atención Nutricional Infantil Antímano (CANIA), within the period between January 1999 and December 2007. Children with prematurity backgrounds, pubertal growth spurts, or with chronic pathologies, whether defined or under study, were excluded. The Dugdale & Griffiths two-skinfold equation for boys and girls shorter than 150 cm and 140 cm, respectively was used to obtain the fat body mass required to estimate the AKS index. The variables were measured by standardized anthropometrics technicians, with quality control every 4 months as recommended by international standards. Descriptive statistics of the AKS index and variables used for their calculation were obtained, as well as index percentiles 3, 10, 25, 50, 75, 90, and 97. Tests applied included Kolmogorov-Smirnoff, Anova one-way, Chi Square, Tukey and bivariated correlations (p < 0.05). The AKS index behavior exhibited higher values in the boys, decreasing with age in both sexes, ranging from 1.28 to 1.04 in the boys and from 1.17 to 0.94 in the girls. Statistically significant differences were found for each age and sex. These results provide the AKS index percentile distribution values needed for nutritional assessments in pediatric ages. These values should be validated and their effectiveness should be studied.

Metabolic syndrome is associated with long-term morbidity and mortality after adult liver transplantation (LT). Whether pediatric LT recipients have a higher prevalence of metabolic syndrome remains controversial. In a cross-sectional study, we evaluated pediatric LT recipients aged 8-30 years using National Health and Nutrition Examination Survey (NHANES) protocols. LT recipients were matched by gender, race/ethnicity, and age with controls from NHANES. Pediatric LT recipients (n = 83), after adjusting for overweight/obesity and glucocorticoid use, had increased prevalence of prehypertension and hypertension, impaired glucose tolerance (IGT; 2-h glucose after oral glucose tolerance test ≥140 mg/dL), and low high-density lipoprotein compared to matched NHANES controls (n = 235) despite a lower prevalence of overweight/obesity. Among LT recipients, the adjusted odds of IGT doubled for every 7.5 years taking calcineurin inhibitors (odds ratio = 2.10, 95% confidence interval 1.06-4.17 per 7.5 years taking calcineurin inhibitors, p = 0.03). Among all subjects with IGT, LT recipients had a lower prevalence of overweight/obesity and less insulin resistance (homeostatic model assessment of insulin resistance) than did controls with IGT. Among normal weight subjects, LT recipients were significantly more likely than controls to have prehypertension/hypertension, IGT, low high-density lipoprotein, and metabolic syndrome. Pediatric LT recipients have unique metabolic syndrome profiles and risk factors and will require tailored screening and management protocols. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

The objective of the study was to compare estimates of pediatric cumulative exposure and lifetime attributable risk (LAR) of radiation-induced cancer from dental radiology between cleft palate (CP) subjects and age- and gender-matched controls (non-CP), with and without orthodontic treatment. The radiation exposure frequency of CP subjects and non-CP controls with and without orthodontic treatment was compared for two-dimensional radiography (intra-oral, panoramic and cephalometric radiography), computed tomography (CT), and cone-beam CT (CBCT) using cumulative radiation dose as an estimate. From this dose estimate, the age- and gender-dependent risk for radiation-induced stochastic effects was calculated for each patient group. CP patients received more radiographic examinations than non-CP controls, with the exception of intra-oral radiographs. The cumulative dose to CP patients was considerably higher (1963 μSv at the age of 20 years) than non-CP patients with (597 μSv) and without (383 μSv) orthodontic treatment, primarily due to the higher frequency of CT scanning. Accordingly, CP patients had a three to five times higher LAR than non-CP patients. This study suggests a significantly higher lifetime radiation exposure to CP patients than non-CP controls from dental radiographic procedures. Diagnostic benefits from the use of CT and CBCT in children must be justified and appropriate dose optimization strategies implemented. The present study indicates the need for proper justification and optimization of pediatric exposures in dentistry, with a special focus on high-risk groups.

To determine the efficacy of nasogastric administration of omeprazole suspension in raising the gastric pH >4 in critically ill pediatric patients and to determine the most appropriate dosing regimen for this indication. Open-label pharmacodynamic study. Twenty-six bed tertiary-care pediatric intensive care unit. Mechanically ventilated children aged 1-18 yrs with an additional risk factor for stress ulcer formation. Continuous gastric pH monitoring was performed during administration and dose titration of omeprazole suspension to achieve the goal of gastric pH >4 for greater than 75% of the dosing interval. Data were collected from 18 patients. Subjects were categorized based on the pharmacologic response to nasogastric administration of 1 mg/kg omeprazole suspension (maximum 20 mg) as rapid (n = 9), late (n = 5), and nonresponders (n = 4). Rapid responders required 0.72 mg/kg per day omeprazole suspension to achieve adequate gastric pH elevation for stress ulcer prophylaxis. Late responders required 1.58 mg/kg per day. Nonresponders did not achieve adequate elevation of gastric pH for stress ulcer prophylaxis. Nasogastric administration of omeprazole suspension has variable efficacy in critically ill pediatric patients. Half of the studied subjects either required significant dose titrations to achieve gastric acid suppression or did not respond to nasogastric administration of omeprazole suspension.

In 2014, the overall rate of smartphone use in Korea was 83 and 89.8 % in children and adolescents. The rate of smartphone use differs according to region (urban vs. rural) and age (younger grade vs. older grade). We investigated risk and protective factors associated with pediatric dry eye disease (DED) in relation to smartphone use rate according to region and age. We enrolled 916 children and performed an ocular exam that included slit lamp exam and tear break-up time. A questionnaire administered to children and their families consisted of video display terminal (VDT) use, outdoor activity, learning, and modified ocular surface disease index (OSDI) score. DED was defined based on the International Dry Eye Workshop guidelines (Objective signs: punctate epithelial erosion or short tear break-up time; subjective symptoms: modified OSDI score) We performed statistical analysis of risk factors and protective factors in children divided into groups as follows: DED vs. control, urban vs. rural, younger grade (1st to 3rd) vs. older grade (4th to 6th). A total of 6.6 % of children were included in the DED group, and 8.3 % of children in the urban group were diagnosed with DED compared to 2.8 % in the rural group (P = 0.03). The rate of smartphone use was 61.3 % in the urban group and 51.0 % in the rural group (P = 0.04). In total, 9.1 % of children in the older-grade group were diagnosed with DED compared to 4 % in the younger-grade group (P = 0.03). The rate of smartphone use was 65.1 % in older-grade children and 50.9 % in younger-grade children (P < 0.001). The mean daily duration of smartphone use was longer in the DED group than controls (logistic regression analysis, P < 0.001, OR = 13.07), and the mean daily duration of outdoor activities was shorter in the DED group than controls (logistic regression analysis, P < 0.01, OR = 0.33).

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. 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-area 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. 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 2 for <1 yr; 1.74 and 1.90 Gy cm 2 for 1 to <5 yr; 2.83 and 3.22 Gy cm 2 for 5 to <10 yr; and 7.34 and 8.68 Gy cm 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 2 /kg) for diagnostic and therapeutic procedures. 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

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

The purpose of this study was to improve the reliability and validity of skeletal age assessment using an open and compact pediatric hand magnetic resonance (MR) imaging scanner. We used such a scanner with 0.3-tesla permanent magnet to image the left hands of 88 healthy children (aged 3.4 to 15.7 years, mean 8.8 years), and 3 raters (2 orthopedic specialists and a radiologist) assessed skeletal age using those images. We measured the strength of agreement in ratings by values of weighted Cohen's κ and the proportion of cases excluded from rating because of motion artifact and inappropriate positioning. We compared the current results with those of a previous study in which 93 healthy children (aged 4.1 to 16.4 years, mean 9.7 years) were examined with an adult hand scanner. The κ values between raters exceeded 0.80, which indicates almost perfect agreement, and most were higher than those of the previous study. The proportion of cases excluded from rating because of motion artifact or inappropriate positioning was also reduced. The results indicate that use of the compact pediatric hand scanner improved the reliability and validity of skeletal age assessments.

Background Myocardial strain is a sensitive measure of ventricular systolic function. Two-dimensional speckle-tracking echocardiography (2DSE) is an angle-independent method for strain measurement but has not been validated in pediatric subjects. We evaluated the accuracy and reproducibility of 2DSE-measured strain against reference tagged MRI-measured strain in pediatric subjects with normal hearts and those with single ventricle (SV) of left ventricle (LV) morphology s/p Fontan procedure. Methods Peak systolic circumferential (CS) and longitudinal (LS) strains in segments (n = 16) of LVs in age and BSA matched 20 healthy and 12 pediatric subjects with tricuspid atresia s/p Fontan procedure were measured by 2DSE and tagged MRI. Average (global) and regional segmental strains measured by two methods were compared using Spearman and Bland-Altman analyses. Results 2DSE and tagged MRI measured global strains demonstrated close agreements, which were better for LS than CS and in normal LVs than in SVs (95% limits of agreement: +0.0% to +3.12%, −2.48 % to +1.08%, −4.6% to +1.8% and −3.6% to +1.8% respectively). There was variability in agreement between regional strains with wider limits in apical than in basal regions in normal LVs and heterogeneous in SVs. The strain values were significantly (p < 0.05) higher in normal LVs than in SVs except for basal LSs, which were similar in both cohorts. The regional strains in normal LVs demonstrated an apico-basal magnitude gradient whereas SVs showed heterogeneity. The reproducibility was the most robust for images obtained with frame rates between 60 and 90 frame/sec; global LS in both cohorts; and basal strains in normal LVs. Conclusions 2DSE-measured strains agree with MRI-measured strain globally but vary regionally particularly in SVs. Global strain may be more robust tool for the cardiac function evaluation than regional strain in SV physiology. The reliability of 2DSE measured strain is affected by the frame rate

This descriptive study was conducted to determine the validity and reliability in Turkey of the Pediatric Quality of Life Inventory Cancer Module (PedsQL 3.0) for children aged 8-12 in the hematology-oncology polyclinics of two university hospitals in Istanbul during the period 2006-2007. The data collection instruments were the Pediatric Quality of Life Inventory (PedsQL 4.0), the Pediatric Quality of Life Inventory Cancer Module (PedsQL 3.0) and a socio-demographic questionnaire, applied for 146 children diagnosed with cancer and 146 parents. Cronbach's alpha coefficients for the PedsQL 3.0 were found to be 0.602-0.982 for sub-groups with the children's form, 0.644-0.966 with the parents' form. The scale was found to give a significantly high level of reliability (0.60 ≤ ± < 0.80). Significant and directly proportional correlations were demonstrated between the forms for children and parents. It was concluded that the PedsQL 3.0 cancer module is a valid and reliable tool for assessing the quality of life of Turkish children, aged 8-12, diagnosed with cancer.

The aim of this cross-sectional study was to determine the associations between self-reported subjective physical and cognitive age, and actual physical and cognitive functions among community-dwelling older people aged 75 years and older. The sample comprised 275 older adults aged 75-91 years. Two questions were asked regarding subjective age: 'How old do you feel physically?' and 'How old do you feel cognitively?' To assess physical functions, we measured handgrip strength, knee extension strength, standing balance and walking speed. Tests of attention, executive function, processing speed and memory were performed to assess actual cognitive function. Subjective physical and cognitive age was associated with performance on all of the physical and cognitive tests, respectively (p < 0.01). We also found that older adults who reported themselves as feeling older than their chronological age had a slower walking speed and lower scores for word-list memory recall than those who did not report themselves as feeling older than their actual age. These findings suggest that promoting a fast walking speed and good memory function may help to maintain a younger subjective physical and cognitive age in older adults aged 75 years and older.

A cross-sectional study of insight and family accommodation in pediatric obsessive-compulsive disorder

PubMed Central

2013-01-01

Background Factors predicting treatment outcome in pediatric patients with obsessive-compulsive disorder (OCD) include disease severity, functional impairment, comorbid disorders, insight, and family accommodation (FA). Treatment of pediatric OCD is often only partly successful as some of these predictors are not targeted with conventional therapy. Among these, insight and FA were identified to be modifiable predictors of special relevance to pediatric OCD. Despite their clinical relevance, insight and FA remain understudied in youth with OCD. This study examined the clinical correlates of insight and FA and determined whether FA mediates the relationship between symptom severity and functional impairment in pediatric OCD. Methods This was a cross-sectional, outpatient study. Thirty-five treatment-naive children and adolescentswith DSM-IV diagnosis of OCD (mean age: 13.11 ± 3.16; 54.3% males) were included. Standard questionnaires were administered for assessing the study variables. Insight and comorbidities were assessed based on clinician’s interview. Subjects were categorized as belonging to a high insight or a low insight group, and the differences between these two groups were analyzed using ANOVA. Pearson’s correlation coefficients were calculated for the remaining variables of interest. Mediation analysis was carried out using structural equation modeling. Results Relative to those in the high insight group, subjects in the low insight group were younger, had more severe disease and symptoms, and were accommodated to a greater extent by their families. In addition, comorbid depression was more frequent in subjects belonging to the low insight group. Family accommodation was positively related to disease severity, symptom severity, and functional impairment. Family accommodation totally mediated the relationship between symptom severity and functional impairment. Conclusions Results support the differences in the diagnostic criteria between adult and

Older adults have a high prevalence of gait and balance disturbances and falls. Normal aging is associated with significant striatal dopaminergic denervation, which might be a previously unrecognized additional contributor to geriatric falls. This study investigated the relationship between the severity of age-associated striatal dopaminergic denervation (AASDD) and falls in community-dwelling subjects. Community-dwelling subjects who did not have a clinical diagnosis to explain falls (n = 77: 43 female, 34 male; mean age 61.4 +/− 16.4; range 20–85) completed clinical assessment and brain dopamine transporter (DAT) [11C]beta-CFT (2-beta-carbomethoxy-3beta-(4-fluorophenyl) tropane) positron emission tomography imaging followed by 6 months of prospective fall monitoring using diaries. Results showed a significant inverse relationship between striatal DAT activity and age (r = −0.82, p < 0.001). A total of 26 subjects (33.8%) reported at least one fall, with 5 subjects (6.5%) reporting two or more falls. While no significant difference was noted in striatal DAT activity between nonfallers (n = 51) and fallers (n = 26; f = 0.02, not significant), striatal DAT activity was modestly reduced in the small subgroup of recurrent fallers compared with the other subjects (f = 5.07, p < 0.05). Findings indicate that AASDD does not explain isolated self-reported falls in community-dwelling subjects. However, it may be a contributing factor in the small subgroup of subjects with recurrent falls. PMID:20157861

To study free- and protein-bound cobalamin absorption and the correlation with atrophic gastritis in healthy middle-aged and older subjects. A cross-sectional study. Fifty-two healthy subjects, aged 26 to 87 years, apparently free from conditions known to influence the cobalamin status. Middle-aged subjects were defined as those younger than 65 years of age (median age 57 years) and older subjects as those 65 years and older (median age 75 years). Protein-bound cobalamin absorption was assessed by 48-hour urinary excretion method following oral administration of scrambled egg yolk, labeled in vivo with 57 Co-cobalamin by injecting a hen with 57 Co-cyanocobalamin. The percentage of 57 Co-cobalamin bound to protein was 65%. Free cobalamin absorption was assessed by 48-hour urinary excretion method following oral administration of crystalline 57 Co-cyanocobalamin. Plasma cobalamin, folate and fasting plasma gastrin, and pepsinogen A and C concentrations were determined. The median urinary excretion of egg yolk 57 Co-cobalamin in middle-aged subjects was 12.3% (25th and 75th percentiles 10.5%-14.5%) compared with 11.7% (25th and 75th percentiles 9.8%-13.6%) in older subjects (P = .283). The median urinary excretion after administration of free 57 Co-cobalamin in middle-aged subjects was 25.7% (25th and 75th percentiles 20.6%-30.7%) compared with 27.9% (25th and 75th percentiles 21.4%-34.5%) in older subjects (P = .694). Neither egg yolk nor free 57 Co-cobalamin excretion correlated with age. A ratio of pepsinogen A to pepsinogen C less than 1.6, indicating atrophic gastritis, was found in 13 subjects. Within the atrophic gastritis group, 11 subjects had a pepsinogen A concentration greater than or equal to 17 micrograms/L, indicating mild to moderate atrophic gastritis, and two subjects had a pepsinogen A concentration less than 17 micrograms/L, indicating severe atrophic gastritis or gastric atrophy. All subjects had normal fasting plasma gastrin concentrations. Free

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.

Although small series have suggested that younger age is associated with less favorable outcome after severe traumatic brain injury (TBI), confounders and biases have limited our understanding of this relationship. We hypothesized that there would be an association between age and mortality in children within an ongoing observational, cohort study. The first 200 subjects from the Approaches and Decisions for Acute Pediatric TBI trial were eligible for this analysis (inclusion criteria: severe TBI (Glasgow Coma Scale [GCS] score ≤ 8], age 18 years, and intracranial pressure (ICP) monitor placed; exclusion: pregnancy). Children with suspected abusive head trauma (AHT) were excluded to avoid bias related to the association between AHT and mortality. Demographics, and prehospital and resuscitation events were collected/analyzed, and children were stratified based on age at time of injury (< 5, 5-< 11, 11-18 years) and presented as mean ± standard error of the mean (SEM). Analyses of variance were used to test the equality of the means across the group for continuous variable, and Chi-square tests were used to compare percentages for discrete variables (post hoc comparisons were made using t test and Bonferroni corrections, as needed). Kaplan-Meier curves were generated for each age subgroup describing the time of death, and log-rank was used to compare the curves. Cox proportional hazards regression models were used to assess the effect of age on time to death while controlling for covariates. In the final cohort (n = 155, 45 excluded for AHT), overall age was 9.2 years ± 0.4 and GCS was 5.3 ± 0.1. Mortality was similar between strata (14.0, 20.0, 20.9%, respectively, p = 0.58). Motor vehicle accidents were the most common mechanism across all strata, while falls tended to be more common in the youngest stratum (p = 0.08). The youngest stratum demonstrated increased incidence of spontaneous hypothermia at presentation and decreased hemoglobin

Local patient dose diagnostic reference levels in pediatric interventional cardiology in Chile using age bands and patient weight values

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

Ubeda, Carlos, E-mail: cubeda@uta.cl; Miranda, Patricia; Vano, Eliseo

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

Objective Cochlear implantation has become the mainstay of treatment for children with severe-to-profound sensorineural hearing loss (SNHL). Yet, despite mounting evidence on the clinical benefits of early implantation, little data are available on the long-term societal benefits and comparative effectiveness of this procedure across various ages of implantation--a choice parameter for parents and clinicians with high prognostic value for clinical outcome. As such, the aim of the current study is to evaluate a model of the consequences of the timing of this intervention from a societal economic perspective. Average cost-utility of pediatric cochlear implantation by age at intervention will be analyzed. Design Prospective, longitudinal assessment of health-utility and educational placement outcomes in 175 children recruited from 6 US centers between November 2002 and December 2004, who had severe-to-profound SNHL onset within 1 year of age, underwent cochlear implantation before 5 years of age, and had up to 6 years of post-implant follow-up that ended in November 2008 to December 2011. Costs of care were collected retrospectively and stratified by pre-operative, operative, and post-operative expenditures. Incremental costs and benefits of implantation were compared between the three age groups and relative to a non-implantation baseline. Results Children implanted at <18 months of age gained an average of 10.7 QALYs over their projected lifetime as compared to 9.0 and 8.4 QALYs for those implanted between 18 and 36 months and at >36 months of age, respectively. Medical and surgical complication rates were not significantly different between the 3 age groups. Additionally, mean lifetime costs of implantation were similar between the 3 groups, at approximately $2,000/child/year (77.5 year life expectancy), yielding costs of $14,996, $17,849, and $19,173 per QALY for the youngest, middle, and oldest implant age groups, respectively.

Pediatric lung transplantation

PubMed Central

2017-01-01

Pediatric lung transplantation has been undertaken since the 1980s, and it is today considered an accepted therapy option in carefully selected children with end-stage pulmonary diseases, providing carefully selected children a net survival benefit and improved health-related quality of life. Nowadays, >100 pediatric lung transplants are done worldwide every year. Here, specific pediatric aspects of lung transplantation are reviewed such as the surgical challenge, effects of immunosuppression on the developing pediatric immune system, and typical infections of childhood, as it is vital to comprehend that children undergoing lung transplants present a real challenge as children are not ‘just small adults’. Further, an update on the management of the pediatric lung transplant patient is provided in this review, and future challenges outlined. Indications for lung transplantation in children are different compared to adults, the most common being cystic fibrosis (CF). However, the primary diagnoses leading to pediatric lung transplantation vary considerably by age group. Furthermore, there are regional differences regarding the primary indication for lung transplantation in children. Overall, early referral, careful patient selection and appropriate timing of listing are crucial to achieve real survival benefit. Although allograft function is to be preserved, immunosuppressant-related side effects are common in children post-transplantation. Strategies need to be put into practice to reduce drug-related side effects through careful therapeutic drug monitoring and lowering of target levels of immunosuppression, to avoid acute-reversible and chronic-irreversible renal damage. Instead of a “one fits all approach”, tailored immunosuppression and a personalized therapy is to be advocated, particularly in children. Further, infectious complications are a common in children of all ages, accounting for almost 50% of death in the first year post

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

To date, not much is known about the psychological and motivational factors underlying technology use in late life. What are the interindividual determinants that lead older adults to invest in using technological innovations despite the age-related physiological changes that impose challenges on behavioral plasticity in everyday life? This research explores interindividual differences in subjective technology adaptivity - a general technology-related motivational resource that accounts for technology use in late life. More specifically, we investigate the influence of this factor relative to demographic characteristics, personality traits, and functional limitations in a longitudinal sample of community-dwelling older adults. We report results from a paper-and-pencil survey with 136 older adults between 59 and 92 years of age (mean = 71.4, SD = 7.4). Of those participants, 77 participated in a 2-year follow-up. We assessed self-reports of technology use, subjective technology adaptivity, functional limitations, and the personality traits openness to new experiences and neuroticism. Higher levels of subjective technology adaptivity were associated with technology use at the first measurement as well as increased use over the course of 2 years. Subjective technology adaptivity is a significant predictor of technology use in old age. Our findings contribute to improving the understanding of interindividual differences when using technological innovation in late life. Moreover, our findings have implications in the context of user involvement and may contribute to the successful development of innovative technology for older adults. © 2017 S. Karger AG, Basel.

Evidence supporting the use of music during pediatric physical therapy intervention is limited. The purpose of this single-subject design was to evaluate the effects of music on patient progress, the amount of crying during therapy, and parent satisfaction with physical therapy services. The subject was an infant girl with Erb's palsy who participated in this study from age 8 months to age 20 months. An A-B-A withdrawal single-subject design was used. The patient's progress was assessed by using the T.I.M.E. The amount of crying was documented in the Crying Log. A parent satisfaction questionnaire was administered three times over the course of the study. The subject's progress in the music intervention period increased on three of five primary subtests of the T.I.M.E. The amount of crying decreased and parent satisfaction increased when music was played during therapy. Music may be used by pediatric physical therapists to decrease the patient's crying, increase parent satisfaction, and possibly to increase the child's rate of progress. Further research conducted with a group of infants and toddlers may help generalize these findings to a wider patient population.

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

Subjective age has been shown to reliably predict a variety of psychological and physical health outcomes, yet our understanding of its determinants is still quite limited. Using data from the Aging as Future project, the authors examined the degree to which views of aging influence subjective age and how this influence varies across cultures and domains of everyday functioning. Using data from 1,877 adults aged from 30 to 95 years of age collected in China, Germany, and the United States, they assessed how general attitudes about aging and perceptions of oneself as an older adult influenced subjective age estimates in 8 different domains of functioning. More positive attitudes about aging were associated with older subjective ages, whereas more positive views of self in old age were associated with younger subjective age. It is hypothesized that these effects are reflective of social-comparison processes and self-protective mechanisms. These influences varied considerably over contexts, with views of aging having a greater impact in domains associated with stronger negative stereotypes of aging (e.g., health) compared to those with more positive ones (e.g., family). Culture also moderated the impact of aging views in terms of the strength of prediction, direction of effect, and age of greatest influence, presumably due to cultural differences in the salience and strength of aging-related belief systems across contexts. The results illustrate the contextual sensitivity of subjective age and highlight the role played by an individual's views of old age-both in general and regarding oneself-in determining their own experience of aging.

Significant changes in body composition are known to occur with aging. The aim of the present study was to provide a normative reference of body composition and to investigate age and sex-related differences in healthy subjects by multifrequency bioelectrical impedance analyzer (BIA).A cross-sectional study was conducted on a sample of 3451 healthy Chinese adults, 1611 males and 1840 females. The volunteers were enrolled in 5 different age bands (18-30, 31-40, 41-50, 51-60, 60+). All subjects were measured for weight and height and submitted to BIA, to determine body composition. Body composition measures accounted for differences between men and women.A decrease in fat-free mass and increase in percent body fat was observed with aging, although the phenomenon was proved to be attenuated in women. The central and visceral redistribution of fat mass was also shown along lifetime.This study is a report on body composition of healthy subjects, to be used as an important data for future investigations and differences between nationalities and countries.

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

Canine pulp ratios in estimating pensionable age in subjects with questionable documents of identification.

One of the most interesting reasons for needing to estimate age in adult subjects is to ascertain the age of a person of questionable pensionable age. This problem is becoming increasingly important in Europe, owing to the high number of immigrants without valid birth certificates. The aim of this paper is to evaluate the application of the apposition of secondary dentine of canines by the method of Cameriere et al. [10], in order to estimate the pensionable age of subjects without proper birth certificates. Periapical X-rays of 180 canines from 90 subjects aged between 50 and 79, 46 men and 44 women, were analysed. Estimated ages were used to test the medico-legal question as to whether an individual was older or younger than 65 years of age. In subjects under 65, age was correctly evaluated in 91% and 89% of individuals using maxillary and mandibular canines, respectively. In subjects over 65, of pensionable age, estimates were correct in 85% and 88% of cases, respectively. The proportion of individuals with correct classifications was 89% for both maxillary and mandibular canines taken together. In only four subjects, the results of maxillary and mandibular canines were discordant; in the other 86 subjects, the test of maxillary and mandibular canines yielded concordant results. Among the latter, the proportion of individuals who were really aged 65 years or older, and who were correctly estimated as such, was 94%, and the proportion of individuals younger than 65 years of age who were correctly estimated as such was 96%.

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.

A mood-induction paradigm was implemented in a sample of 144 adults covering midlife and old age (40-80 years) to investigate associations between mood and subjective age. Sad or neutral mood was induced by texts and music pieces. Subjective age was operationalized as felt age relative to chronological age. Participants receiving the sad-mood induction reported changes toward older felt ages from pre- to postinduction. Participants receiving the neutral-mood induction reported comparable levels of subjective age at pre- and postinduction. Effects were comparable across middle- and older aged participants. Results suggest that sad affective states might dampen subjective age. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

The aims of this study were to develop a computerized program for objectively evaluating skeletal maturation on cephalometric radiographs, and to apply the new method to Brazilian subjects. The samples were taken from the patient files of Oral Radiological Clinics from the North, Northeast, Midwest and South regions of the country. A total of 717 subjects aged 7.0 to 15.9 years who had lateral cephalometric radiographs and hand-wrist radiographs were selected. A cervical vertebral computerized analysis was created in the Radiocef Studio 2 computer software for digital cephalometric analysis, and cervical vertebral bone age was calculated using the formulas developed by Caldas et al.17 (2007). Hand-wrist bone age was evaluated by the TW3 method. Analysis of variance (ANOVA) and the Tukey test were used to compare cervical vertebral bone age, hand-wrist bone age and chronological age (P < 0.05). No significant difference was found between cervical vertebral bone age and chronological age in all regions studied. When analyzing bone age, it was possible to observe a statistically significant difference between cervical vertebral bone age and hand-wrist bone age for female and male subjects in the North and Northeast regions, as well as for male subjects in the Midwest region. No significant difference was observed between bone age and chronological age in all regions except for male subjects in the North and female subjects in the Northeast. Using cervical vertebral bone age, it might be possible to evaluate skeletal maturation in an objective manner using cephalometric radiographs.

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.

In an institutional review board-approved study, 25 pediatric subjects diagnosed with chronic or recurrent otitis media were observed over a period of six months with optical coherence tomography (OCT). Subjects were followed throughout their treatment at the initial patient evaluation and preoperative consultation, surgery (intraoperative imaging), and postoperative follow-up, followed by an additional six months of records-based observation. At each time point, the tympanic membrane (at the light reflex region) and directly adjacent middle-ear cavity were observed in vivo with a handheld OCT probe and portable system. Imaging results were compared with clinical outcomes to correlate the clearance of symptoms in relation to changes in the image-based features of infection. OCT images of most all participants showed the presence of additional infection-related biofilm structures during their initial consultation visit and similarly for subjects imaged intraoperatively before myringotomy. Subjects with successful treatment (no recurrence of infectious symptoms) had no additional structures visible in OCT images during the postoperative visit. OCT image findings suggest surgical intervention consisting of myringotomy and tympanostomy tube placement provides a means to clear the middle ear of infection-related components, including middle-ear fluid and biofilms. Furthermore, OCT was demonstrated as a rapid diagnostic tool to prospectively monitor patients in both outpatient and surgical settings.

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 demonstrate the use of a state-maintained database (CHILD Profile) to monitor immunization status of pediatric cochlear implant recipients, and to assess compliance with current vaccination recommendations for cochlear implant users managed at Seattle Children's Hospital. Cross-sectional study. Tertiary academic pediatric hospital. Subjects were 260 patients with cochlear implants managed at Seattle Children's Hospital between July 1, 1995, and May 1, 2008. Patients were stratified by age groups (0-2 years, 2-5 years, 5-10 years, > 10 years). Using a statewide children's immunization registry (CHILD Profile), subjects were assessed with regard to their immunization status for Haemophilus influenzae type B vaccination (HiB), 7-valent pneumococcal conjugate vaccination (PCV-7), and 23-valent pneumococcal polysaccharide vaccine (PPV-23). Two hundred twenty-five of 260 subjects (87%) were registered in CHILD Profile; 126 of 225 (56%) were up to date with CDC recommendations for patients with cochlear implants. PPV-23 was the vaccination most likely to be incomplete. Age was predictive of immunization status only with HiB vaccination. A statewide immunization registry can be used to monitor the immunization status of cochlear implant recipients. Subjects were significantly more likely to be incomplete for PPV-23 than for either PCV-7 or HiB vaccinations. Copyright © 2010 American Academy of Otolaryngology–Head and Neck Surgery Foundation.

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.

Next-generation sequencing technologies will likely be used with increasing frequency in pediatric research. One consequence will be the increased identification of individual genomic research findings that are incidental to the aims of the research. Although researchers and ethicists have raised theoretical concerns about incidental findings in the context of genetic research, next-generation sequencing will make this once largely hypothetical concern an increasing reality. Most commentators have begun to accept the notion that there is some duty to disclose individual genetic research results to research subjects; however, the scope of that duty remains unclear. These issues are especially complicated in the pediatric setting, where subjects cannot currently but typically will eventually be able to make their own medical decisions at the age of adulthood. This article discusses the management of incidental findings in the context of pediatric genomic research. We provide an overview of the current literature and propose a framework to manage incidental findings in this unique context, based on what we believe is a limited responsibility to disclose. We hope this will be a useful source of guidance for investigators, institutional review boards, and bioethicists that anticipates the complicated ethical issues raised by advances in genomic technology.

To investigate changes in cerebral blood flow (CBF) in gray matter (GM) between 6 months and 15 years of age and to provide CBF values for the brain, GM, white matter (WM), hemispheres and lobes. Between 2013 and 2016, we retrospectively included all clinical MRI examinations with arterial spin labeling (ASL). We excluded subjects with a condition potentially affecting brain perfusion. For each subject, mean values of CBF in the brain, GM, WM, hemispheres and lobes were calculated. GM CBF was fitted using linear, quadratic and cubic polynomial regression against age. Regression models were compared with Akaike's information criterion (AIC), and Likelihood Ratio tests. 84 children were included (44 females/40 males). Mean CBF values were 64.2 ± 13.8 mL/100 g/min in GM, and 29.3 ± 10.0 mL/100 g/min in WM. The best-fit model of brain perfusion was the cubic polynomial function (AIC = 672.7, versus respectively AIC = 673.9 and AIC = 674.1 with the linear negative function and the quadratic polynomial function). A statistically significant difference between the tested models demonstrating the superiority of the quadratic (p = 0.18) or cubic polynomial model (p = 0.06), over the negative linear regression model was not found. No effect of general anesthesia (p = 0.34) or of gender (p = 0.16) was found. we provided values for ASL CBF in the brain, GM, WM, hemispheres, and lobes over a wide pediatric age range, approximately showing inverted U-shaped changes in GM perfusion over the course of childhood.

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

PubMed

Reinhard-Rupp, Jutta; Klohe, Katharina

2017-08-03

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.

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.

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

Infliximab (IFX) is efficacious for induction and maintenance of remission in pediatric patients with moderate-to-severe inflammatory bowel disease (IBD). It has, however, not been studied in patients 7 years old and younger. Our aim was to characterize efficacy and safety of IFX therapy in this cohort. This was a retrospective study of patients with IBD ages 7 years and younger, treated with IFX between 1999 and 2011. Medical records were reviewed for age of diagnosis, disease phenotype, therapy, surgery, IFX infusion dates, dose, and intervals. Outcome measures included physician global assessment, corticosteroid requirement, and adverse events. Thirty-three children (ages 2.4-7 years) were included. Twenty patients had Crohn disease, 4 had ulcerative colitis, and 9 had indeterminate colitis. Maintenance of IFX therapy at 1, 2, and 3 years was 36%, 18%, and 12%, respectively. Patients of age 5 years and younger had the lowest rates of maintenance of therapy at 25% at year 1, and 10% at years 2 and 3 combined. Nine percent of all of the patients demonstrated response measured by the physician global assessment and were steroid free at 1 year. There were 8 infusion reactions. There were no malignancies, serious infections, or deaths. IFX demonstrated a modest response rate and a low steroid-sparing effect in patients with IBD 7 years old and younger. Although this is a limited study, there appears to be a trend for decreased sustained efficacy with IFX in this age group, particularly in children 5 years old and younger, when compared with the previously published literature in older children.

The Combined Effects of Daily Stressors and Major Life Events on Daily Subjective Ages.

Stressors may be a contributing factor in determining how old an individual feels, looks, or would like to be. Currently, little research has been devoted to understanding the relationship between stressors and subjective age in older adults. We focus on the combined impact of major life-event stressors and daily stressors on multiple indicators of subjective age: felt age, ideal age, and look age. Furthermore, we examine the process by which daily stressors relate to subjective ages by testing whether positive affect, control, and negative affect mediate this relationship. Using a daily-diary design, the current study measured older adults' (60-96 years old) stressors, subjective ages, personal control, and affect. Felt, ideal, and look ages each demonstrated a unique pattern of interactions between daily stressors and major life-event stressors. Furthermore, our findings suggest that on the daily level, the relationship between stressors and felt age is mediated by negative affect but not by control and positive affect. Findings indicate the need to consider the broader contextual picture of stressors, as well as their differential impact on multiple indicators of subjective age. © The Author 2015.

Since infection with human immunodeficiency virus (HIV) was first described, there have been many advances in its diagnosis, monitoring and treatment. However, few contributions are related to the area of health care quality. In this sense, the Spanish Study Group on AIDS (GESIDA) has developed a set of quality care indicators for adult patients living with HIV infection that includes a total of 66 indicators, 22 of which are considered to be relevant. Standards were calculated for each of them in order to reflect the level of the quality of care offered to these patients. Similar documents for pediatric patients are currently lacking. Preparation of a set of quality care indicators applicable to pediatric patients based on the GESIDA document and the Spanish Guidelines for monitoring of pediatric patients infected with HIV. Each indicator was analysed with respect to the required standards in all patients under 18 years of age followed-up in our Unit, with the aim of evaluating the quality of care provided. A total of 61 indicators were collected (51 from the GESIDA document and 10 from currently available pediatric guidelines), 30 of which were considered to be relevant. An overall compliance of 81%-83% was obtained when assessing the relevant indicators. The availability of health care quality standards is essential for the care of pediatric HIV-infected patients. The assessment of these indicators in our Unit yielded satisfactory results. Copyright © 2012 Elsevier España, S.L. y Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

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

Scientific advances provide opportunities to improve pediatric environmental health

The health consequences of contaminants in the environment, with respect to the health of children and infants, recently have been dramatically brought to public attention by the motion pictures Erin Brockovich and A Civil Action. These productions focused public attention on the potential link between water contaminants and pediatric health, a continuing subject of public concern. As a consequence of the increasing production of new commercial chemicals, many chemicals have appeared in the scientific and public awareness as potential threats to health. These new or novel compounds eventually distribute in the environment and often are termed emerging contaminants. Gitterman and Bearer stated, "Children may serve as unwitting sentinels for society; they are often the youngest exposed to many environmental toxicants and may become the youngest in age to manifest adverse responses." The discipline of pediatric environmental health is still in its adolescence, but it will be increasingly important as new chemicals are generated and as more is learned about the health effects of chemicals already in commerce. Here, we provide an overview of recent advances in biomonitoring and environmental monitoring of environmental contaminants including emerging contaminants. Our purpose in writing this commentary is to make pediatricians aware of the current resources available for learning about pediatric environmental health and of ongoing research initiatives that provide opportunities to improve pediatric environmental health.

To assess pressure ulcer (PrU) treatment in Swiss hospitalized pediatric patients and to determine whether there are differences in PrU treatment, according to demographic characteristics of the patients. A descriptive multicenter point prevalence study was conducted in June 2009 in all German-speaking pediatric hospitals in Switzerland. All hospitalized patients from birth up to 17 years or younger in 14 Swiss pediatric hospitals, including all pediatric departments, were assessed. A total of 412 patients participated in this study. The instrument and method of the Dutch National Prevalence Measurement of Care Problems were used. Thirty-five percent of the patients had a PrU. Almost all of these PrUs (94.1%) were of category 1. The most severe PrUs occurred in patients older than 8 years. Age of the patient and department were the only characteristics that significantly influenced the occurrence of PrU categories 2 to 4. Pressure ulcer categories 2 to 4 were mostly covered with hydrocolloid or polyurethane foam dressings. No pediatric-specific guideline regarding PrU treatment is used in the involved hospitals. Most patients had category 1 PrUs, so appropriate prevention to decrease any further trauma in these patients was necessary. Severe PrUs (categories 2-4) are mostly limited to older pediatric (aged >8 years) patients with chronic conditions or after surgery intervention. A PrU treatment guideline adapted for pediatric needs is recommended.

Experimental Injury Biomechanics of the Pediatric Head and Brain

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.

European perspectives on pediatric formulations.

2008-11-01

The 2007 European Union (EU) regulation on medicinal products for pediatric use may change the present unsatisfying situation in the EU by stimulating research and development of medicines for use in children through rewards and incentives. This commentary reflects on the new EU regulations and guidelines, with special attention paid to the impact on pediatric formulation science. The focus of this article is on the EU perspective for pediatric formulations and highlights the differences compared with the pediatric drug formulation situation in the United States. Materials for this article were gathered during a literature search of MEDLINE and Chemical Abstracts (1970-October 2008) using the following terms: paediatric/pediatric drug formulations, age-appropriate dosage forms, child-appropriate medicines, and paediatric/pediatric regulation. Since the EU legislation on medicines for children came into force in 2007, a great emphasis has been placed on creating new organizations, scientific networks, and programs dealing with pediatric medicines and child-appropriate drug formulations. Although the US legislation was an appropriate model, the EU introduced some novel measures to improve the current situation, such as the Paediatric Investigation Plan and the Paediatric Use Marketing Authorisation. For globally operating pharmaceutical companies, the peculiarities of the European market have a strong impact on their product development strategies. Because the European approach demands early investigations into drug formulations for children, various issues must be resolved, including the following: choosing formulations for each age group, determining which excipients may be used in the formulation and which delivery device is appropriate, and predicting the taste sensation of an oral formulation. Numerous initiatives and networks are evolving in Europe. An important future task will be the coordination of these activities and the linking to other groups working on

This study aims to determine prevalence and incidence of epilepsy in the US pediatric population. We analyzed commercial claims and Medicaid insurance claims data between 2008 and 2012. Over 8 million continuously enrolled lives aged 0 to 19 years were included. Our definition of a prevalent case of epilepsy was based on International Classification of Diseases-coded diagnoses of epilepsy or seizures and evidence of prescribed antiepileptic drugs. Incident cases were identified in subjects continuously enrolled for ≥2 years of which the first 2 years had no indication of epilepsy or seizures. The overall prevalence estimate for 2012 was 6.8 per 1,000 children. The overall incidence estimate for 2012 was 104 per 100,000 pediatric population. This study provides estimates of the prevalence and incidence of epilepsy in the US pediatric population, using large claims datasets from multiple US population sectors. The findings appear reasonably representative of the US-insured pediatric population. © The Author(s) 2015.

Peripheral neuropathy is a known side effect of several chemotherapy agents, including vinca alkaloids and platinum-based chemotherapy. Early recognition and monitoring of this side effect is an important role of the pediatric oncology nurse. There are a variety of peripheral neuropathy assessment tools currently in use, but the usefulness of these tools in identifying and grading neuropathy in children varies, and there is currently no standardized tool in place to evaluate peripheral neuropathy in pediatric oncology. A systematic review was performed to identify the peripheral neuropathy assessment tools that best evaluate the early onset and progression of peripheral neuropathy in pediatric patients receiving vincristine. Because of the limited information available in pediatric oncology, this review was extended to any pediatric patient with neuropathy. A total of 8 studies were included in the evidence synthesis. Based on available evidence, the pediatric-modified Total Neuropathy Scale (ped-m TNS) and the Total Neuropathy Score-pediatric version (TNS-PV) are recommended for the assessment of vincristine-induced peripheral neuropathy in children 6 years of age and older. In addition, several studies demonstrated that subjective symptoms alone are not adequate to assess for vincristine-induced peripheral neuropathy. Nursing assessment of peripheral neuropathy should be an integral and regular part of patient care throughout the course of chemotherapy treatment.

Pediatric Cervical Spine Injuries: A Rare But Challenging Entity.

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.

Background Pediatric chest injuries were infrequent in our practice, but the outbreak of the Syrian crisis resulted in an increase in number and a change in the pattern of thoracic trauma incidents. We compared our experience of pediatric chest injuries before and during the crisis. Methods We reviewed the records of 256 children aged 12.8 ± 5 years who were admitted to our hospital with the diagnosis of chest trauma over a 12-year period. Collected data included mechanism of injury, associated injuries, method of management, length of hospital stay, complications, and mortality. Results The incidence of pediatric chest injuries increased significantly following the outbreak of the crisis, and penetrating injuries prevailed, mainly due to shrapnel, bullets, and stab wounds. Forty percent of patients with blunt injuries and 20% of those with penetrating injuries were managed conservatively, whereas urgent thoracotomies were indicated in 10%, mostly in patients with penetrating injuries. Associated injuries were more frequent in patients with blunt injuries and resulted in a longer hospital stay and an increased mortality rate. The overall mortality rate was 7.8% and it was higher in children younger than 7 years of age and in patients who had been subjected to blunt injuries. Conclusions There has been a recent substantial upsurge in the incidence of pediatric thoracic trauma, with a predominance of penetrating injuries. Most patients could be managed nonoperatively, but a small subset required an open thoracotomy. The presence of associated injuries constitutes the main determinant of prognosis in this group of patients.

Symptoms of psoriasis can be embarrassing and distressing, and may increase risk of developing psychiatric disorders in young people. We sought to compare incidences of psychiatric disorders between pediatric patients with psoriasis and psoriasis-free control subjects. Patients (<18 years) with continuous health plan enrollment 6 months before and after first psoriasis diagnosis (index date) were selected (Thomson Reuters MarketScan database, 2000-2006 [Thomson Reuters, New York, NY]). Patients with psoriasis (N = 7404) were matched 1:5 on age and sex to psoriasis-free control subjects (N = 37,020). Patients were followed from index date to first diagnosis of a psychiatric disorder (ie, alcohol/drug abuse, depression, anxiety disorder, bipolar disorder, suicidal ideation, eating disorder), end of data availability, or disenrollment. Patients with psychiatric diagnoses or psychotropic medication use before the index date were excluded. Cox proportional hazard models controlling for age, sex, and comorbidities were used to estimate the effect of psoriasis on risks of developing psychiatric disorders. Patients with psoriasis were significantly more at risk of developing psychiatric disorders versus control subjects (5.13% vs 4.07%; P = .0001; hazard ratio = 1.25; P = .0001), especially depression (3.01% vs 2.42%; P = .0036; hazard ratio = 1.25; P = .0053) and anxiety (1.81% vs 1.35%; P = .0048; hazard ratio = 1.32; P = .0045). Retrospective, observational studies of medical claims data are typically limited by overall quality and completeness of data and accuracy of coding for diagnoses and procedures. Pediatric patients with psoriasis had an increased risk of developing psychiatric disorders, including depression and anxiety, compared with psoriasis-free control subjects.

The purpose of this study was to identify the clinical pediatric orthopaedic articles with at least 100 citations published in all orthopaedic journals and to examine their characteristics. All journals dedicated to orthopaedics and its subspecialties were selected from the Journal Citation Report 2001 under the subject category "orthopedics." Articles cited 100 times or more were identified using the database of the Science Citation Index Expanded (SCI-EXPANDED, 1900 to present). The articles were ranked in a comprehensive list. Two authors independently reviewed the full text of each article and applied the inclusion and exclusion criteria to the list of articles. The 2 lists were then compared. All disagreements were resolved by consensus with input from the senior author. The final list of pediatric orthopaedic articles was then compiled. There were a total of 49 journals under the search category "orthopedics." Five journals were excluded as they were non-English journals. The remaining 44 journals were screened for articles with at least 100 citations. A total of 135 clinical pediatric orthopaedic articles cited at least 100 times were included. The most cited article was cited 692 times. The mean number of citations per article was 159 (95% confidence interval, 145-173). All the articles were published between 1949 and 2001, with 1980 and 1989 producing the most citation classics (34). The majority (90) originated from the United States, followed by the United Kingdom (12) and Canada (11). Scoliosis/kyphosis was the most common topic with 26 papers. The second most common subject was hip disorders (24). Therapeutic studies were the most common study type (71). Ninety-seven papers were assigned a 4 for level of evidence. The list of citation classics in pediatric orthopaedic articles is useful for several reasons. It identifies important contributions to the field of pediatric orthopaedics and their originators; it facilitates the understanding and discourse

In the United States, the Best Pharmaceuticals for Children Act and the Pediatric Research Equity Act continue to promote clinical trials in pediatric populations across all age ranges. In 2014 and 2015, over 70 changes were made to drug labels with updates on information regarding pediatric populations. Additionally, multiple new therapies have received first-approvals for the treatment of pediatric indications ranging form rare genetic metabolic diseases to oncology. In the European Union, there have been more than 30 new authorizations for medicines used in children and 130 approved pediatric investigation plans. Despite the progress that has been made over the last two years, much work remains to further the development of safe and effective therapies for pediatric patients. PMID:27426903

Cranial traumas have different particularities in infants, toddlers, preschool child, school child and teenagers. The assessment of these cases must be individualized according to age. It is completely different in children that in adults. Trauma scales, very useful in grading the severity and predicting outcome in traumatic brain injury, used in adults must be adapted in children. Children have age-related specificity and anatomic particularities, for each of this period of development. Neurotrauma scales, specific for infants and children, such as Pediatric Coma Scale, Children’s Coma Score, Trauma Infant Neurological Score, Glasgow Coma Scale, Liege Scale are reviewed, as well as neurotrauma outcome scales, like Glasgow Outcome Scale, modified Rankin score, KOSCHI score and Barthel Index. The authors present these scales in an exhaustive manner for thoroughgoing pediatric neurotrauma standards. PMID:20108520

In 2010, researchers reported that the two US-licensed rotavirus vaccines contained DNA or DNA fragments from porcine circovirus (PCV). Although PCV, a common virus among pigs, is not thought to cause illness in humans, these findings raised several safety concerns. In this study, we sought to determine whether viruses, including PCV, could be detected in ileal tissue samples of children vaccinated with one of the two rotavirus vaccines. A broad spectrum, novel DNA detection technology, the Lawrence Livermore Microbial Detection Array (LLMDA), was utilized, and confirmation of viral pathogens using the polymerase chain reaction (PCR) was conducted. The LLMDA technologymore » was recently used to identify PCV from one rotavirus vaccine. Ileal tissue samples were analyzed from 21 subjects, aged 15–62 months. PCV was not detected in any ileal tissue samples by the LLMDA or PCR. LLMDA identified a human rotavirus A from one of the vaccinated subjects, which is likely due to a recent infection from a wild type rotavirus. LLMDA also identified human parechovirus, a common gastroenteritis viral infection, from two subjects. Additionally, LLMDA detected common gastrointestinal bacterial organisms from the Enterobacteriaceae , Bacteroidaceae , and Streptococcaceae families from several subjects.

This article was designed to consider the congenital age-specific features of palm dermatoglyphics in the adults subjects (including the type of the papillary patterns, axial tri-radii, the termini of palmar main lines, the rudiments of palmar lines, the dermatoglyphic ridge count between the stable anatomical structures). The objective of the study was to look for the new diagnostic markers of the biological age. It included the identification of the palm prints obtained from 180 Caucasoid men and 120 women at the age varying from 16 to 80 years. The results of the mathematical and statistical analysis provided the basis for drawing up the list of 18 attributes of palm dermatoglyphics significantly (p<0.05) differing in the frequency of occurrence between the representatives of individual age groups. The methods are proposed allowing to use these findings for the expert evaluation of the age of unknown subjects.

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.

Prediabetes in Pediatric Recipients of Liver Transplant: Mechanism and Risk Factors.

To investigate the role of calcineurin inhibitor exposure and states of insulin resistance-obesity and adolescence-in prediabetes after pediatric liver transplant via oral glucose tolerance testing, which previously has not been done systematically in these at-risk youths. This was a cross-sectional study of 81 pediatric recipients of liver transplant. Prediabetes was defined as impaired glucose tolerance (IGT; glucose ≥140 mg/dL at 2 hours) or impaired fasting glucose (IFG, ≥100 mg/dL). Corrected insulin response (CIR) was calculated as measure of insulin secretion, corrected for glucose (CIR 30 , CIR 60 , CIR 120 ). Subjects were aged 8.1-30.0 years and 1.1-24.7 years post-transplant; 44% had prediabetes-27% IGT, 14% IFG, and 3% both. IGT was characterized by insulin hyposecretion, with lower CIR 60 and CIR 120 in IGT than subjects with normal glucose tolerance. Subjects with tacrolimus trough >6 µg/mL at study visit had lower CIR 120 than those with trough ≤6 µg/mL and those off calcineurin-inhibitors. Mean of tacrolimus troughs preceding the study visit, years since transplant, and rejection episodes were not associated significantly with lower CIR. CIR suppression by tacrolimus was most pronounced >6 years from transplant. Overweight/obese subjects and adolescents who retained normal glucose tolerance had greater CIR than those who were IGT. IGT after pediatric liver transplant is driven by inadequate insulin secretion. It is quite common but not detectable with fasting laboratory values-the screening recommended by current guidelines. Calcineurin inhibitors suppress insulin secretion in these patients in a dose-dependent manner. Given the recent focus on long-term outcomes and immunosuppression withdrawal in these children, longitudinal studies are warranted to investigate whether IGT is reversible with calcineurin inhibitor minimization.

Pediatric sepsis

Sepsis is the leading cause of death in children worldwide. Although the diagnosis and management of sepsis in infants and children is largely influenced by studies done in adults, there are important considerations relevant for pediatrics. This article highlights pediatric-specific issues related to the definition of sepsis and its epidemiology and management. We review how the capacity of the immune system to respond to infection develops over early life. We also bring attention to primary immune deficiencies that should be considered in children recurrently infected with specific types of organisms. The management of pediatric sepsis must be tailored to the child’s age and immune capacity, and to the site, severity, and source of the infection. It is important for clinicians to be aware of infection-related syndromes that primarily affect children. Although children in developed countries are more likely to survive severe infections than adults, many survivors have chronic health impairments. PMID:24225404

The Chicago Classification (CC) facilitates interpretation of high-resolution manometry (HRM) recordings. Application of this adult based algorithm to the pediatric population is unknown. We therefore assessed intra and interrater reliability of software-based CC diagnosis in a pediatric cohort. Thirty pediatric solid state HRM recordings (13M; mean age 12.1 ± 5.1 years) assessing 10 liquid swallows per patient were analyzed twice by 11 raters (six experts, five non-experts). Software-placed anatomical landmarks required manual adjustment or removal. Integrated relaxation pressure (IRP4s), distal contractile integral (DCI), contractile front velocity (CFV), distal latency (DL) and break size (BS), and an overall CC diagnosis were software-generated. In addition, raters provided their subjective CC diagnosis. Reliability was calculated with Cohen's and Fleiss' kappa (κ) and intraclass correlation coefficient (ICC). Intra- and interrater reliability of software-generated CC diagnosis after manual adjustment of landmarks was substantial (mean κ = 0.69 and 0.77 respectively) and moderate-substantial for subjective CC diagnosis (mean κ = 0.70 and 0.58 respectively). Reliability of both software-generated and subjective diagnosis of normal motility was high (κ = 0.81 and κ = 0.79). Intra- and interrater reliability were excellent for IRP4s, DCI, and BS. Experts had higher interrater reliability than non-experts for DL (ICC = 0.65 vs ICC = 0.36 respectively) and the software-generated diagnosis diffuse esophageal spasm (DES, κ = 0.64 vs κ = 0.30). Among experts, the reliability for the subjective diagnosis of achalasia and esophageal gastric junction outflow obstruction was moderate-substantial (κ = 0.45-0.82). Inter- and intrarater reliability of software-based CC diagnosis of pediatric HRM recordings was high overall. However, experience was a factor influencing the diagnosis of some motility disorders, particularly DES and achalasia. © 2014 John Wiley & Sons

Gender Distribution of Pediatric Stone Formers

2008-09-01

Recent epidemiologic evidence suggests that the gender prevalence among adult stone-formers is changing, with an increasing incidence of stone disease among women. No similar data have ever been reported for the pediatric stone-forming population. We performed a study to define the gender distribution among pediatric stone-formers using a large-scale national pediatric database. Our findings suggest that gender distribution among stone formers varies by age with male predominance in the first decade of life shifting to female predominance in the second decade. In contrast to adults, females in the pediatric population are more commonly affected by stones than are males. The incidence of pediatric stone disease appears to be increasing at a great rate in both sexes. Further studies should build on this hypothesis-generating work and define the effects of metabolic and environmental risk factors that may influence stone risk in the pediatric patient population

Purpose At our institution, speculation amongst medical students and faculty exists as to whether team-based learning (TBL) can improve scores on high-stakes examinations over traditional didactic lectures. Faculty with experience using TBL developed and piloted a required TBL blood disorders (BD) module for third-year medical students on their pediatric clerkship. The purpose of this study is to analyze the BD scores from the NBME subject exams before and after the introduction of the module. Methods We analyzed institutional and national item difficulties for BD items from the NBME pediatrics content area item analysis reports from 2011 to 2014 before (pre) and after (post) the pilot (October 2012). Total scores of 590 NBME subject examination students from examinee performance profiles were analyzed pre/post. t-Tests and Cohen's d effect sizes were used to analyze item difficulties for institutional versus national scores and pre/post comparisons of item difficulties and total scores. Results BD scores for our institution were 0.65 (±0.19) compared to 0.62 (±0.15) nationally (P=0.346; Cohen's d=0.15). The average of post-consecutive BD scores for our students was 0.70(±0.21) compared to examinees nationally [0.64 (±0.15)] with a significant mean difference (P=0.031; Cohen's d=0.43). The difference in our institutions pre [0.65 (±0.19)] and post [0.70 (±0.21)] BD scores trended higher (P=0.391; Cohen's d=0.27). Institutional BD scores were higher than national BD scores for both pre and post, with an effect size that tripled from pre to post scores. Institutional BD scores increased after the use of the TBL module, while overall exam scores remained steadily above national norms. Conclusions Institutional BD scores were higher than national BD scores for both pre and post, with an effect size that tripled from pre to post scores. Institutional BD scores increased after the use of the TBL module, while overall exam scores remained steadily above national

The management of cardiopulmonary bypass for pediatric cardiac surgery is more challenging than that in adults due to the smaller size, immaturity, and complexity of the anatomy in children. Despite major improvements in cardiopulmonary bypass, there remain many subjects of debate. This review article discusses the physiology of cardiopulmonary bypass for pediatric and congenital heart surgery, including topics related to hemodilution, hypothermia, acid-base strategies, inflammatory response, and myocardial protection.

Too many pediatric trampoline injuries.

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

To study the epidemiology and management of pediatric trauma patients as well as the organizational, human and technical resources dedicated to these children from the perspective of the pediatric intensive care unit (PICU). A standardized data collection form was sent to 43 PICUs in Spain. Items inquired about the existence of training courses, trauma clinical practice guidelines and trauma registers, and which physician was in charge of trauma patients. Data on casuistics, the age of trauma patients, and the availability of human and technical resources, were also recorded. Twenty-four PICUs completed the questionnaire. The PICU physician was responsible for trauma patient care in 66% of the hospitals. No training courses were available in 59% of the hospitals. No trauma register was available in 62% of the hospitals. Trauma patients represented 11% of PICU admissions, and most patients were aged up to 14 years old. An anesthetist was always at the hospital in 100% of the hospitals. A radiologist and traumatologist were always at the hospital in 91%, a neurosurgeon in 66% and a pediatric surgeon in 50%. The remaining surgical and medical specialties were on call. Continuous intracranial pressure monitoring was available in 87% of the PICUs, jugular venous saturation monitoring in 54% and continuous electroencephalogram and transcranial Doppler ultrasound in 50%. Computed tomography and ultrasound were available at all times in all hospitals. Magnetic nuclear resonance and echocardiography were available at all times in 44% of the hospitals, and arteriography in 42%. In Spain, the organization of pediatric trauma management is based on pediatric teams under the supervision of a PICU physician. Some hospitals show a lack of technical and human resources. Therefore, the minimum criteria required to consider a hospital as a pediatric trauma center should be established. Trauma training courses are required.

The purpose of this cross-sectional observational study was to determine the distribution and patterns of refractive errors, strabismus, and amblyopia in children seen at a pediatric eye care. The study was conducted in a Private Hospital in Dammam, Kingdom of Saudi Arabia, from March to July 2013. During this period, a total of 1350 children, aged 1-15 years were seen at this Center's Pediatric Ophthalmology Unit. All the children underwent complete ophthalmic examination with cycloplegic refraction. Refractive errors accounted for 44.4% of the cases, the predominant refractive error being hypermetropia which represented 83%. Strabismus and amblyopia were present in 38% and 9.1% of children, respectively. In this clinic-based study, the focus was on the frequency of refractive errors, strabismus, and amblyopia which were considerably high. Hypermetropia was the predominant refractive error in contrast to other studies in which myopia was more common. This could be attributed to the criteria for sample selection since it was clinic-based rather than a population-based study. However, it is important to promote public education on the significance of early detection of refractive errors, and have periodic screening in schools.

While extensive research in toy safety has been performed, data is unavailable with regard to the kinematics of toy swords. To improve upon design criteria, knowledge of a child’s physical capacity is essential. The purpose of this study was to quantify the linear and angular velocities generated by children swinging toy swords. A total of 36 male subjects, ages 4-14 years old, each participated in one trial. Subjects were instructed to swing a toy sword as fast and hard as possible for ~10 seconds. A Vicon motion analysis system was used to capture subject and sword kinematics. Peak linear and angular sword velocities were calculated. A strong correlation was identified between age and velocity. The 8-14 year old males were not significantly different. The 4 year old males generated significantly lower velocities than the 8-14 year old males. The 6 year old males produced significantly lower velocities than the 10- 14 year old males. It was concluded that age had a significant effect on the linear and angular velocities generated by children. The trends observed within this study likely result from typical pediatric and adolescent development. By accounting for the physical capabilities of a specific population, toys can be designed with decreased inherent risks of injury.

The relationships among types of social support and different facets of subjective well-being (i.e., life satisfaction, positive affect, and negative affect) were examined in a sample of 1,111 individuals between the ages of 18 and 95. Using structural equation modeling we found that life satisfaction was predicted by enacted and perceived support, positive affect was predicted by family embeddedness and provided support, and negative affect was predicted by perceived support. When personality variables were included in a subsequent model, the influence of the social support variables were generally reduced. Invariance analyses conducted across age groups indicated that there were no substantial differences in predictors of the different types of subjective well-being across age. PMID:25045200

Spatial normalization is a very important step in the processing of magnetic resonance imaging (MRI) data. So the quality of brain templates is crucial for the accuracy of MRI analysis. In this paper, using the classical protocol and the optimized protocol plus nonlinear deformation, we constructed the T1 whole brain templates and apriori brain tissue data from 69 Chinese pediatric MRI data (age 7-16 years). Then we proposed a new assessment method to evaluate our templates. 10 pediatric subjects were chosen to do the assessment as the following steps. First, the cerebellum region, the region of interest (ROI), was located on both the pediatric volume and the template volume by an experienced neuroanatomist. Second, the pediatric whole brain was mapped to the template with affine and nonlinear deformation. Third, the parameter, derived from the second step, was used to only normalize the ROI of the child to the ROI of the template. Last, the overlapping ratio, which described the overlapping rate between the ROI of the template and the normalized ROI of the child, was calculated. The mean of overlapping ratio normalized to the classical template was 0.9687, and the mean normalized to the optimized template was 0.9713. The results show that the two Chinese pediatric brain templates are comparable and their accuracy is adequate to our studies.

The subjective global assessment (SGA) is a simple, sensitive tool used to identify nutritional risk. It is widely used in the adult population, but there is little evidence on its effectiveness in children with cancer. This cross-sectional study was undertaken to demonstrate significant correlation between a simplified version of the Patient-Generated SGA (PG-SGA) and anthropometric assessment to identify nutritional status in children recently diagnosed with cancer. The nutritional status of 70 pediatric cancer patients was assessed with the PG-SGA and anthropometric measurements. The relation between the assessments was tested with ANOVA, independent samples t-test, Kappa statistic, and non-parametric Spearman and Kendall correlation coefficient. The PG-SGA divided the patients into four groups: well nourished, mildly, moderately and severely malnourished. The prevalence of malnutrition according to the PG-SGA was 21.4%. The correlations (r ≥ 0.300, p < 0.001) and the concordance (k ≥ 0.327, p < 0.001) between the PG-SGA and anthropometric indicators were moderate and significant. The results indicate that the PG-SGA is a valid tool for assessing nutritional status in hospitalized children recently diagnosed with cancer. It is important to emphasize that the subjective assessment does not detect growth retardation, overweight or obesity.

Decreased information processing speed (IPS) is frequently reported in pediatric multiple sclerosis (MS) patients. The computerized version of the Symbol Digit Modalities Test (c-SDMT) measures IPS over eight consecutive trials per session and additionally captures changes in performance within the session. Here, we establish normative c-SDMT performance and test-retest reliability in healthy children (HC) and explore differences in the overall c-SDMT-performance between HC and MS patients. This cross-sectional study included 478 HC (237 female, 49.5%) divided into five age groups (2 years each), and 27 MS patients (22 female, 81.5%) aged 8-18 years. The average time to complete the c-SDMT increased with age (|r| 0.70, 95% CI -0.74, -0.64). Test-retest reliability was high (ICC = 0.91) in HC. The total time to complete the c-SDMT did not differ between children with MS and sex- and age- matched HC (p = 0.23). However, MS patients were less likely to show faster performance across all the successive eight trials compared to HC (p = 0.0001). Healthy children demonstrate faster IPS with increasing age, as well as during successive trials of the c-SDMT. The inability of pediatric MS patients to maintain the increase in processing speed over successive trials suggests a reduced capacity for procedural learning, possibly resulting from cognitive fatigue.

Attenuated adult biphasic shocks for prolonged pediatric ventricular fibrillation: support for pediatric automated defibrillators.

PubMed

Berg, Robert A

2004-09-01

To evaluate published data regarding the treatment of prolonged pediatric defibrillation, with special emphasis on the use of attenuated adult biphasic shocks for pediatric defibrillation. Review relevant human and animal literature. Rhythm analysis algorithms from two manufacturers of automated external defibrillators can accurately distinguish shockable from nonshockable rhythms in children. Theoretical considerations and transthoracic impedance data from animals and children suggest that pediatric defibrillation doses should not necessarily vary in a simple weight-based manner. Two piglet studies have established that an attenuated adult biphasic dosage can be successfully used for 3.5- to 24-kg animals in ventricular fibrillation. One study established that the attenuated adult biphasic dosage was at least as safe and effective as the standard monophasic weight-based dosing. This review supports the American Heart Association's new guidelines for pediatric automated external defibrillator usage: "Automated external defibrillators may be used for children 1 to 8 yrs of age who have no signs of circulation. Ideally the device should deliver a pediatric dose. The arrhythmia detection system used in the device should demonstrate high specificity for pediatric shockable rhythms, i.e., it will not recommend delivery of a shock for nonshockable rhythms."

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

SYNOPSIS With the ongoing epidemic of human immune deficiency virus (HIV) infections in the pediatric age group, the delivery of safe and effective antiretroviral therapy to children and adolescents is crucial to save the lives of millions of children worldwide. Antiretroviral drugs have been demonstrated to significantly decrease HIV-associated morbidity and mortality, assure normal growth and development, and improve survival and quality of life in children and adolescents. The immunologic response to HIV infection is closely related to the child’s development and creates age specific parameters for the evaluation of therapeutic response to antiretroviral therapy in pediatric HIV disease. In addition to the changes in immunological response to HIV infection, the development and maturation of organ systems involved in drug absorption, distribution, metabolism, and elimination determines significant changes in the pharmacokinetics of antiretroviral drugs throughout the childhood. Multiple factors including age-specific adherence barriers, changes in social and economical surroundings, and psychological and sexual maturation affect the choices and outcomes of the treatment of pediatric HIV disease. In this chapter we will review the evolution of antiretroviral treatment from early infancy through adolescence. PMID:23036246

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

Purpose In this study, the authors examined the effect of hearing loss on subjective reports of fatigue in school-age children using a standardized measure. Methods As part of a larger ongoing study, the authors obtained subjective ratings of fatigue using the Pediatric Quality of Life Inventory (PedsQL) Multidimensional Fatigue Scale (Varni, Burwinkle, Katz, Meeske, & Dickinson, 2002). This standardized scale provides a measure of general fatigue, sleep/rest fatigue, cognitive fatigue, and an overall composite measure of fatigue. To date, data from 10 children with hearing loss (CHL) and 10 age-matched children with normal hearing (CNH) have been analyzed. Results These preliminary results show that subjective fatigue is increased in school-age children with hearing loss (Cohen's d = 0.78–1.90). In addition, the impact of hearing loss on fatigue in school-age children appears pervasive across multiple domains (general, sleep/rest, and cognitive fatigue). Conclusion School-age CHL reported significantly more fatigue than did CNH. These preliminary data are important given the negative academic and psychosocial consequences associated with fatigue. Further research is needed to determine the underlying mechanisms responsible for this increased fatigue in school-age children with hearing loss, and to identify factors that may modulate (e.g., degree of loss) and mediate (e.g., hearing aid or cochlear implant use) its impact.

Pediatric endotracheal intubation (ETI) is difficult and can have serious adverse events when performed by paramedics in the prehospital setting. Paramedics may use the King Laryngeal Tube airway (KLT) in difficult adult airways, but only limited data describe their application in pediatric patients. To compare paramedic airway insertion speed and complications between KLT and ETI in a simulated model of pediatric respiratory arrest. This prospective, randomized trial included paramedics and senior paramedic students with limited prior KLT experience. We provided brief training on pediatric KLT insertion. Using a random allocation protocol, participants performed both ETI and KLT on a pediatric mannequin (6-month old size) in simulated respiratory arrest. The primary outcomes were 1) elapsed time to successful airway placement (seconds), and 2) proper airway positioning. We compared airway insertion performance between KLT and ETI using the Wilcoxon signed-ranks test. Subjects also indicated their preferred airway device. The 25 subjects included 19 paramedics and 6 senior paramedic students. Two subjects had prior adult KLT experience. Airway insertion time was not statistically different between the KLT (median 27 secs) and ETI (median 31 secs) (p = 0.08). Esophageal intubation occurred in 2 of 25 (8%) ETI. Airway leak occurred in 3 of 25 (12%) KLT, but ventilation remained satisfactory. Eighty-four percent of the subjects preferred the KLT over ETI. Paramedics and paramedic students demonstrated similar airway insertion performance between KLT and ETI in simulated, pediatric respiratory arrest. Most subjects preferred KLT. KLT may provide a viable alternative to ETI in prehospital pediatric airway management.

Objectives Perceptions of future time are of key interest to aging research because of their implications for subjective well-being. Interestingly, perceptions about future time are only moderately associated with age, pointing to a vast heterogeneity in future time perceptions among older adults. We examine associations between future time perceptions, age, and subjective well-being across two studies, including moderations by individual resources. Method Using data from the Berlin Aging Study (N = 516; Mage = 85 years), we link one operationalization (subjective nearness to death) and age to subjective well-being. Using Health and Retirement Study data (N = 2,596; Mage = 77 years), we examine associations of another future time perception indicator (subjective future life expectancy) and age with subjective well-being. Results Consistent across studies, perceptions of limited time left were associated with poorer subjective well-being (lower life satisfaction and positive affect; more negative affect and depressive symptoms). Importantly, individual resources moderated future time perception–subjective well-being associations with those of better health exhibiting reduced future time perception–subjective well-being associations. Discussion We discuss our findings in the context of the Model of Strength and Vulnerability Integration. PMID:26437862

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

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.

The first aim of this study was to explore the prevalence of loneliness and subjective health complaints (SHCs) among school-aged children in Finland. The second aim was to analyse to what extent perceived loneliness explains any variance in SHCs among school-aged children. A representative sample of 5925 Finnish children and adolescents from grades 5 ( M age =11.8 years), 7 ( M age =13.8) and 9 ( M age =15.8) completed the Health Behaviour in School-aged Children (HBSC) survey. Descriptive statistics were used to examine the prevalence of health complaints and loneliness. Structural equation modelling was used to test how strongly loneliness was associated with SHCs. The prevalence of loneliness and SHCs was higher among girls and increased with age. Loneliness was a significant predictor of health complaints, especially of psychological symptoms among girls and among ninth grade students. The findings indicate that loneliness is a major risk to the health and well-being of school-aged children. The strong association between loneliness and SHCs highlights the importance of active preventive actions to reduce loneliness.

Objective To examine long-term outcome in children with trichotillomania. Method We conducted follow-up clinical assessments an average of 2.8 ± 0.8 years after baseline evaluation in 30 out of 39 children who previously participated in a randomized, double-blind, placebo-controlled trial of N-acetylcysteine (NAC) for pediatric trichotillomania. Our primary outcome was change in hairpulling severity on the Massachusetts General Hospital-Hairpulling Scale (MGH-HPS) between the end of the acute phase and follow-up evaluation. We also obtained secondary measures examining styles of hairpulling, comorbid anxiety and depressive symptoms, as well as continued treatment utilization. We examined both correlates and predictors of outcome (change in MGH-HPS score) using linear regression. Results None of the participants continued to take NAC at the time of follow-up assessment. No significant changes in hairpulling severity were reported over the follow-up period. Subjects reported significantly increased anxiety and depressive symptoms but improvement in automatic pulling symptoms. Increased hairpulling symptoms during the follow-up period were associated with increased depression and anxiety symptoms and increased focused pulling. Older age and greater focused pulling at baseline assessment were associated with poor long-term prognosis. Conclusions Our findings suggest that few children with trichotillomania experience a significant improvement in trichotillomania symptoms if behavioral treatments are inaccessible or have failed to produce adequate symptom relief. Our findings also confirm results of previous cross-sectional studies that suggest an increased risk of depression and anxiety symptoms with age in pediatric trichotillomania. Increased focused pulling and older age among children with trichotillomania symptoms may be associated with poorer long-term prognosis. PMID:26139231

To assess the agreement between the results of the Subjective Global Nutritional Assessment questionnaire, adapted for children and adolescents of the Brazilian population, and the nutritional status assessment method through growth curves and the classification of the World Health Organization in a pediatric hospital service. This was an analytical, quantitative, cross-sectional study. During the data collection period, the nutritional status of all patients from 0 to 12 years of age, admitted to the pediatric unit of a university hospital, was concomitantly assessed according to the Subjective Global Nutritional Assessment and World Health Organization curves. To determine the assessment and agreement between these methods, the Kappa and Kendall coefficients were used, respectively, considering a significance level of 5%. Sixty-one children participated, with a predominance of males. It was observed that the highest frequency of equivalent results occurred among the group classified as well nourished, and that only the height/age variable showed a close agreement between the methods. Additionally, there was a good correlation only for the weight/height variable between the assessment tools used. Due to the low agreement between the methods, the combination of both may be beneficial for the nutritional assessment of pediatric patients, collaborating with the early diagnosis of nutritional alterations and facilitating the use of adequate dietary therapy.

Rationale: Although asthma is usually considered to originate in childhood, adult-onset disease is being increasingly reported. Objectives: To contrast the proportion and natural history of adult-onset versus pediatric-onset asthma in a community-based cohort. We hypothesized that asthma in women is predominantly of adult onset rather than of pediatric onset. Methods: This study used data from the Coronary Artery Risk Development in Young Adults (CARDIA) cohort in the United States over a 25-year period. Adult- and pediatric-onset asthma phenotypes were studied, as defined by age at onset of 18 years or older. Subjects with asthma were categorized by sex, obesity, atopy, smoking, and race by mean age/examination year, using a three-way analysis of covariance model. Natural history of disease was examined using probabilities derived from a Markov chain model. Measurements and Main Results: Asthma of adult onset became the dominant (i.e., exceeded 50%) phenotype in women by age 40 years. The age by which adult-onset asthma became the dominant phenotype was further lowered for obese, nonatopic, ever-smoking, or white women. The prevalence trend with increasing time for adult-onset disease was greater among subjects with nonatopic than atopic asthma among both sexes. Furthermore, adult-onset asthma had remarkable sex-related differences in risk factors. In both sexes, the quiescent state for adult-onset asthma was less frequent and also “less stable” over time than for pediatric-onset asthma. Conclusions: Using a large national cohort, this study challenges the dictum that most asthma in adults originates in childhood. Studies of the differences between pediatric- and adult-onset asthma may provide greater insight into the phenotypic heterogeneity of asthma. PMID:23802814

2013-05-01

The purpose of this summary paper is to discuss the current knowledge of the impact of age on diastolic function of the left ventricle. Data from the literature: Reports published till this time have convincingly demonstrated a significant relationship of age to diastolic function of the left ventricle. Ageing is a physiological process accompanied by structural changes in both myocardium and arterial bed resulting in worsening of parameters characterizing the left ventricular diastolic function. This "physiological" diastolic dysfunction in the elderly subjects can be explained by the deterioration of passive left ventricular filling properties and by worsening of left ventricular relaxation. The detailed analysis of published reports shows problems in distiguishing this "physiological" diastolic dysfunction resulting from physiological tissue ageing from "pathological" diastolic dysfunction reflecting a disease of cardiovascular system. To interprete correctly values of parameters quantifying diastolic function of the left ventricle, one should take into account the age of subjects under the examination. Further studies are necessary to distinguish exactly "physiological" deterioration of diastolic function associated with ageing from really "pathological" diastolic dysfunction in the elderly subjects.

Despite known benefits of diversity, certain racial/ethnic groups remain underrepresented in academic pediatrics. Little research exists regarding unconscious racial attitudes among pediatric faculty responsible for decisions on workforce recruitment and retention in academia. This study sought to describe levels of unconscious racial bias and perceived barriers to minority recruitment and retention among academic pediatric faculty leaders. Authors measured unconscious racial bias in a sample of pediatric faculty attending diversity workshops conducted at local and national meetings in 2015. A paper version of the validated Implicit Association Test (IAT) measured unconscious racial bias. Subjects also reported perceptions about minority recruitment and retention. Of 68 eligible subjects approached, 58 (85%) consented and completed the survey with IAT. Of participants, 83% had leadership roles and 93% were involved in recruitment. Participants had slight pro-white/anti-black bias on the IAT (M = 0.28, SD = 0.49). There were similar IAT scores among participants in leadership roles (M = 0.33, SD = 0.47) and involved in recruitment (M = 0.28, SD = 0.43). Results did not differ when comparing participants in local workshops to the national workshop (n = 36, M = 0.29, SD = 0.40 and n = 22, M = 0.27, SD = 0.49 respectively; p = 0.88). Perceived barriers to minority recruitment and retention included lack of minority mentors, poor recruitment efforts, and lack of qualified candidates. Unconscious pro-white/anti-black racial bias was identified in this sample of academic pediatric faculty and leaders. Further research is needed to examine how unconscious bias impacts decisions in academic pediatric workforce recruitment. Addressing unconscious bias and perceived barriers to minority recruitment and retention represent opportunities to improve diversity efforts. Copyright © 2017 National Medical Association.

2016-08-01

Recent Pediatric Advanced Life Support (PALS) guidelines have deemphasized the use of advanced airways in short transport. It is unclear if guideline recommendations have altered practice. We sought to determine if a temporal change exists in the number of prehospital pediatric trauma intubations since the 2005 PALS guidelines update. This is an institutional review board-approved, retrospective, single-center study. Reviewed all pediatric trauma activations where patients younger than 19 years were intubated at the scene, en route or at the level 1 trauma center during 2006 to 2011. Specific complications collected were esophageal intubations, mainstem intubations and need for re-intubations. There were 1012 trauma activations, 1009 pediatric patients, 300 (29.7%) intubated during transport to Children's Hospital of Wisconsin Pediatric Trauma Center (PTC) or upon arrival. Mean age of 9.5 ± 5.9 years. Fifty-seven percent (n = 172) were intubated before PTC, 31.7% (n = 95) field intubations, 25.7% (n = 77) outside facility intubations. 44% (n = 132) at PTC. Age was not a significant variable. There was no difference in the proportion of injured children requiring intubation who were intubated before arrival to the PTC. Those intubated in the field versus a facility had significantly increased mortality (P = 0.0002), longer hospital days (P = 0.0004) including intensive care unit days (P = 0.0003) and ventilator days (P = 0.0003) even when adjusted for illness severity. There was no significant change in the proportion of pretrauma room intubations following the 2005 PALS guidelines even when adjusted for illness or injury severity. Children injured farther from the PTC and more severely injured children were more likely to be intubated before arrival at the PTC.

TH-AB-207A-06: The Use of Realistic Phantoms to Predict CT Dose to Pediatric Patients

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

Carver, D; Kost, S; Fraser, N

Purpose: To predict pediatric patient dose from diagnostic CT scans using Monte Carlo simulation of realistic reference phantoms of various ages, weights, and heights. Methods: A series of deformable pediatric reference phantoms using Non-Uniform Rational B-Splines (NURBS) was developed for a large range of ages, percentiles, and reference anatomy. Individual bones were modeled using age-dependent factors, and red marrow was modeled as functions of age and spatial distribution based on Cristy1. Organ and effective doses for the phantom series were calculated using Monte Carlo simulation of chest, abdominopelvic, and chest-abdomen-pelvis CT exams. Non-linear regression was performed to determine the relationshipmore » between dose-length-product (DLP)-normalized organ and effective doses and phantom diameter. Patient-specific voxel computational phantoms were also created by manual segmentation of previously acquired CT images for 40 pediatric patients (0.7 to 17 years). Organ and effective doses were determined by Monte Carlo simulation of these patient-specific phantoms. Each patient was matched to the closest pediatric reference phantom based primarily on age and diameter for all major organs within the torso. Results: A total of 80 NURBS phantoms were created ranging from newborn to 15 years with height/weight percentiles from 10 to 90%. Organ and effective dose normalized by DLP correlated strongly with exponentially decreasing average phantom diameter (R{sup 2} > 0.95 for most organs). A similar relationship was determined for the patient-specific voxel phantoms. Differences between patient-phantom matched organ-dose values ranged from 0.37 to 2.39 mGy (2.87% to 22.1%). Conclusion: Dose estimation using NURBS-based pediatric reference phantoms offers the ability to predict patient dose before and after CT examinations, and physicians and scientists can use this information in their analysis of dose prescriptions for particular subjects and study types.

Individuals with schizophrenia (SZ) exhibit multiple premature age-related phenotypes and die ~20years prematurely. The accelerated aging hypothesis of SZ has been advanced to explain these observations, it posits that SZ-associated factors accelerate the progressive biological changes associated with normal aging. Testing the hypothesis has been limited by the absence of robust, meaningful, and multi-tissue measures of biological age. Recently, a method was described in which DNA methylation (DNAm) levels at 353 genomic sites are used to produce "DNAm age", an estimate of biological age with advantages over existing measures. We used this method and 3 publicly-available DNAm datasets, 1 from brain and 2 from blood, to test the hypothesis. The brain dataset was composed of data from the dorsolateral prefrontal cortex of 232 non-psychiatric control (NPC) and 195 SZ subjects. Blood dataset #1 was composed of data from whole blood of 304 NPC and 332 SZ subjects, and blood dataset #2 was composed of data from whole blood of 405 NPC and 260 SZ subjects. DNAm age and chronological age correlated strongly (r=0.92-0.95, p<0.0001) in both NPC and SZ subjects in all 3 datasets. DNAm age acceleration did not differ between NPC and SZ subjects in the brain dataset (t=0.52, p=0.60), blood dataset #1 (t=1.51, p=0.13), or blood dataset #2 (t=0.93, p=0.35). Consistent with our previous findings from a smaller study of postmortem brains, our findings suggest there is no acceleration of brain or blood aging in SZ and, thus, do not support the accelerated aging hypothesis of SZ.

While numerous magnetic resonance imaging (MRI) studies have evaluated adults with bipolar disorder (BPD), few have examined MRI changes in children with BPD. To determine volume alterations in children with BPD using voxel-based morphometry, an automated MRI analysis method with reduced susceptibility to various biases. A priori regions of interest included amygdala, accumbens, hippocampus, dorsolateral prefrontal cortex (DLPFC), and orbitofrontal cortex. Ongoing study of the pathophysiology of pediatric BPD. Intramural National Institute of Mental Health; approved by the institutional review board. Patients Pediatric subjects with BPD (n = 20) with at least 1 manic or hypomanic episode meeting strict DSM-IV criteria for duration and elevated, expansive mood. Controls (n = 20) and their first-degree relatives lacked psychiatric disorders. Groups were matched for age and sex and did not differ in IQ. With a 1.5-T MRI machine, we collected 1.2-mm axial sections (124 per subject) with an axial 3-dimensional spoiled gradient recalled echo in the steady state sequence. Image analysis was by optimized voxel-based morphometry. Subjects with BPD had reduced gray matter volume in the left DLPFC. With a less conservative statistical threshold, additional gray matter reductions were found in the left accumbens and left amygdala. No difference was found in the hippocampus or orbitofrontal cortex. Our results are consistent with data implicating the prefrontal cortex in emotion regulation, a process that is perturbed in BPD. Reductions in amygdala and accumbens volumes are consistent with neuropsychological data on pediatric BPD. Further study is required to determine the relationship between these findings in children and adults with BPD.

A Model to Improve Detection of Nonaccidental Pediatric Burns.

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.

Subjective age-of-acquisition norms for 600 Turkish words from four age groups.

The main purpose of this study was to report age-based subjective age-of-acquisition (AoA) norms for 600 Turkish words. A total of 115 children, 100 young adults, 115 middle-aged adults, and 127 older adults provided AoA estimates for 600 words on a 7-point scale. The intraclass correlations suggested high reliability, and the AoA estimates were highly correlated across the four age groups. Children gave earlier AoA estimates than the three adult groups; this was true for high-frequency as well as low-frequency words. In addition to the means and standard deviations of the AoA estimates, we report word frequency, concreteness, and imageability ratings, as well as word length measures (numbers of syllables and letters), for the 600 words as supplemental materials. The present ratings represent a potentially useful database for researchers working on lexical processing as well as other aspects of cognitive processing, such as autobiographical memory.

The objective of this study is to review available data on pediatric thoracic trauma seen at U.S. military treatment facilities in Iraq and Afghanistan and describe the scope of injuries, patterns seen, and associated mortality. The results were compared with adults injured in Iraq and Afghanistan and other reports of pediatric thoracic trauma in the literature. The investigators received approval from the Uniformed Services University of the Health Sciences' institutional review board before the study. The Joint Theatre Trauma Registry was queried for all patients with an ICD-9 code for thoracic trauma. Two-tailed Student's t-test, Mann-Whitney rank sum, χ2, ANOVA, or multiple logistic regression was used as indicated. There were 955 patients under the age of 18 yr, just over 12% of all thoracic trauma. Penetrating injuries were common (73.6%), including gunshot wounds. The most common pediatric diagnoses were contusions (45%), pneumothorax (40%), and rib and/or sternal fractures (18%). The overall mortality for children was 15.2% compared with 13.8% and 9% for civilian adults and Coalition members with thoracic trauma, respectively. Mortality was inversely related to age among pediatric patients. Children under 2 yr of age had the highest mortality (25.1%). Patients under 12 yr of age were more likely to die than those between 12 and 18 (OR 2.02, 95% CI 1.27-3.22) yr. Thoracic vascular injuries and cardiac injuries resulted in the highest mortality among pediatric patients. The presence of a hemothorax was independently associated with an increased risk for mortality (OR 1.78, 95% CI 1.06-2.99) as was a concomitant head injury (OR 2.17, 95% CI 1.33-3.54). There was a 2.7% incidence of burns among pediatric patients with a high associated mortality (46.2%). Nearly one-half of all the children identified required a transfusion (47%). Penetrating injuries predominated and these children commonly required a transfusion. Mortality was inversely related to age

There are many causes of gastrointestinal bleeding (GIB) in children, and this condition is not rare, having a reported incidence of 6.4%. Causes vary with age, but show considerable overlap; moreover, while many of the causes in the pediatric population are similar to those in adults, some lesions are unique to children. The diagnostic approach for pediatric GIB includes definition of the etiology, localization of the bleeding site and determination of the severity of bleeding; timely and accurate diagnosis is necessary to reduce morbidity and mortality. To assist medical care providers in the evaluation and management of children with GIB, the "Gastro-Ped Bleed Team" of the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP) carried out a systematic search on MEDLINE via PubMed (http://www.ncbi.nlm.nih.gov/pubmed/) to identify all articles published in English from January 1990 to 2016; the following key words were used to conduct the electronic search: "upper GIB" and "pediatric" [all fields]; "lower GIB" and "pediatric" [all fields]; "obscure GIB" and "pediatric" [all fields]; "GIB" and "endoscopy" [all fields]; "GIB" and "therapy" [all fields]. The identified publications included articles describing randomized controlled trials, reviews, case reports, cohort studies, case-control studies and observational studies. References from the pertinent articles were also reviewed. This paper expresses a position statement of SIGENP that can have an immediate impact on clinical practice and for which sufficient evidence is not available in literature.

We assessed whether an independent association between inflammatory markers and age-related subclinical atherosclerosis could be found in subjects free from cardiovascular disease. Metabolic parameters, inflammatory and endothelial markers, such as high-sensitivity C-reactive protein, interleukin-6, fibrinogen and von Willebrand factor, as well as the carotid intima-media thickness were assessed in 890 asymptomatic subjects (mean age: 55 years; range: 20-80 years; 80% men) with cardiovascular risk factors. Subjects in the upper quartile (age 61-80 years) showed a significant increase of traditional risk factors, particularly arterial pressure and glucose levels (p < 0.01) as compared with lower quartiles. We also found a significant increase in the levels on inflammatory and endothelial markers (p < 0.001) and intima-media thickness (p < 0.001) in older adults. In the multivarate analysis, after adjustment for cardiovascular risk factors, intima-media thickness was independently associated with inflammation and endothelial dysfunction in older adults (p < 0.01). Besides age, systemic inflammation and vascular damage are associated with subclinical atherosclerosis in asymptomatic subjects. The age-related inflammatory profile may predispose to cardiovascular complications.

The aim of the study was to explore the relationship between repressive adaptive style and self-reports of social adjustment in survivors of pediatric cancer compared to their siblings. We hypothesized that there would be a greater proportion of repressors among survivors of pediatric cancer compared to siblings, and that repressive adaptive style would be significantly associated with more positive self-reports of social adjustment. We utilized a cross-sectional approach. Seventy-seven families participated. Survivors of pediatric cancer (n = 77, 48% male; 8-18 years of age) and one sibling (n = 50, 48% male; 8-18 years of age) completed measures assessing repressive adaptive style and social adjustment. As well, one parent from each family completed a socio-demographic questionnaire. Questionnaire packages were mailed to eligible families who agreed to participate, and were mailed back to investigators in a pre-addressed, pre-stamped envelope. Chi-square analyses revealed there was no significant difference in the proportion of repressors among survivors and siblings. Social adjustment scores were subjected to a two (group: survivor, sibling) by two (repressor, nonrepressor) ANCOVA with gender and age as covariates. There was a significant main effect of repressive adaptive style (F = 5.69, p < .05, η 2 = 0.05) with a modest effect. Survivors and siblings with a repressive style reported significantly higher social adjustment scores (M = 106.91, SD = 11.69) compared to nonrepressors (M = 99.57, SD = 13.45). Repressive adaptive style explains some of the variance in survivors and siblings' self-reports of social adjustment. Future research should aim to better understand the role of the repressive adaptive style in survivors and siblings of children with cancer.

Perceptions of future time are of key interest to aging research because of their implications for subjective well-being. Interestingly, perceptions about future time are only moderately associated with age when looking at the second half of life, pointing to a vast heterogeneity in future time perceptions among older adults. We examine associations between future time perceptions, age, and subjective well-being across two studies, including moderations by individual resources. Using data from the Berlin Aging Study (N = 516; Mage = 85 years), we link one operationalization (subjective nearness to death) and age to subjective well-being. Using Health and Retirement Study data (N = 2,596; Mage = 77 years), we examine associations of another future time perception indicator (subjective future life expectancy) and age with subjective well-being. Consistent across studies, perceptions of limited time left were associated with poorer subjective well-being (lower life satisfaction and positive affect; more negative affect and depressive symptoms). Importantly, individual resources moderated future time perception-subjective well-being associations with those of better health exhibiting reduced future time perception-subjective well-being associations. We discuss our findings in the context of the Model of Strength and Vulnerability Integration. © The Author 2015.

Fractures which need urgent or emergency treatment are common in children and adolescents. This study investigated the incidence patterns of pediatric and adolescent orthopaedic fractures according to age groups and seasons in South Korea based on population data. Data on the number of pediatric and adolescent patients under the age of 18 years who utilized medical services due to fractures were retrieved from the Health Insurance Review and Assessment service in South Korea. The data included four upper extremity and two lower extremity fractures according to four age groups (0-4 years, 5-9 years, 10-14 years, and 15-18 years). Incidences of the fractures were calculated as the incidence per 10,000 per year, and patterns according to age groups and seasons were demonstrated. The annual incidence of clavicle, distal humerus, both forearm bone, distal radius, femoral shaft and tibial shaft fractures were 27.5, 34.6, 7.7, 80.1, 2.5, and 9.6 per 10,000 per year in children and adolescents, respectively. Clavicle and distal radius fractures showed significant seasonal variation for all age groups but femoral shaft fracture showed no significant seasonal variation for any of the age groups. The four upper extremity fractures tended to show greater variations than the two lower extremity fractures in the nationwide database in South Korea. The study results are believed to be helpful in the planning and assignment of medical resources for fracture management in children and adolescents.

Epidemiologic insights into pediatric kidney stone disease.

2010-12-01

The epidemiology of pediatric kidney stone has not yet been as rigorously defined as that of adult kidney stone disease. Herein, we review our recent epidemiologic works characterizing pediatric stone disease using the Kids' Inpatient Database (KID). Specifically we investigated the age and gender distribution of pediatric kidney stone disease, changes in disease prevalence over time, and medical comorbidities associated with this disorder. We identified patients by International Classification of Disease 9th Edition (ICD-9) codes for renal and ureteral calculi as the primary diagnosis. Medical comorbidities were identified using specific comorbidity software. Statistical comparisons between children with and without stone disease were performed. In the first decade of life, stone disease was more prevalent among males than females; however, in the second decade of life females were more commonly affected. Of note, there was a significant increase in treated stone disease across both genders between 1997 and 2003. We also found that the risk of kidney stone diagnosis in children younger than 6 years of age was significantly associated with hypertension and diabetes mellitus. The gender distribution among pediatric stone formers varies significantly by age, although overall females have a greater prevalence than males. There is also a strong association of stone disease and both diabetes and hypertension, although this was only observed in children less than 6 years of age. Taken all together, these findings suggest that urolithiasis in the young child is a complex systemic disease process.

To examine whether subjective sleep quality and sleep duration moderate the association between age and telomere length (TL). Participants completed a demographic and sleep quality questionnaire, followed by a blood draw. Social Neuroscience Laboratory. One hundred fifty-four middle-aged to older adults (age 45-77 y) participated. Participants were excluded if they were on immunosuppressive treatment and/or had a disease with a clear immunologic (e.g., cancer) component. N/A. Subjective sleep quality and sleep duration were assessed using the Pittsburgh Sleep Quality Index (PSQI) and TL was determined using peripheral blood mononuclear cells (PBMCs). There was a significant first-order negative association between age and TL. Age was also negatively associated with the self-reported sleep quality item and sleep duration component of the PSQI. A significant age × self-reported sleep quality interaction revealed that age was more strongly related to TL among poor sleepers, and that good sleep quality attenuated the association between age and TL. Moreover, adequate subjective sleep duration among older adults (i.e. greater than 7 h per night) was associated with TL comparable to that in middle-aged adults, whereas sleep duration was unrelated to TL for the middle-aged adults in our study. The current study provides evidence for an association between sleep quality, sleep duration, and cellular aging. Among older adults, better subjective sleep quality was associated with the extent of cellular aging, suggesting that sleep duration and sleep quality may be added to a growing list of modifiable behaviors associated with the adverse effects of aging.

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.

Reexpansion pulmonary edema: review of pediatric cases.

PubMed

Kira, Shinichiro

2014-03-01

Reexpansion pulmonary edema (RPE) is an increased permeability pulmonary edema that usually occurs in the reexpanded lung after several days of lung collapse. This condition is recognized to occur more frequently in patients under the age of 40 years, but there has been no detailed analysis of reported pediatric cases of RPE to date. For this review, PubMed literature searches were performed using the following terms: 're(-)expansion pulmonary (o)edema' AND ('child' OR 'children' OR 'infant' OR 'boy' OR 'girl' OR 'adolescent'). The 22 pediatric cases of RPE identified were included in this review. RPE was reported in almost the entire pediatric age range, and as in adult cases, the severity ranged from subclinical to lethal. No specific treatment for RPE was identified, and treatment was administered according to the clinical features of each patient. Of the 22 reported cases, 10 occurred during the perioperative period, but were not related to any specific surgical procedures or anesthetic techniques, or to the duration of lung collapse. Pediatric anesthesiologists should be aware that pediatric RPE can occur after reexpansion of any collapsed lung and that some invasive therapies can be useful in severe cases. © 2013 John Wiley & Sons Ltd.

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

Subjective health complaints are common among adolescents. There is evidence that girls are more likely to register complaints than boys. This study examines gender differences in the relationship between daily smoking and recurrent subjective health complaints in school-aged adolescents in the USA. A cross-sectional design with a multistage probability sample was used to survey 13,339 middle and high school students (grades 6 through 10) with the US 2001-2002 Health Behavior in School-Aged Children Survey. Recurrent subjective health complaints were higher for adolescents who smoke daily and experiment with cigarettes than for those who never smoke. In logistic regression analyses, the odds of daily smoking increased twofold for both boys and girls who report recurrent irritability/bad temper. For girls, the odds of daily smoking were higher among those who reported recurrent headache, stomachache and backache compared with never smokers. For boys only recurrent backache and feeling dizzy were associated with increased odds of daily smoking. The relationship between recurrent subjective health complaints and daily smoking provides new insights into both conditions for school-aged adolescents. Findings from this study suggest different patterns of association between daily smoking and recurrent subjective health complaints occur for girls and boys. Further studies are needed to explore causes and treatment of daily smoking and recurrent health complaints among school-aged children. © 2010 Blackwell Publishing Ltd.

In Italy, according to the International Study on Asthma and Allergies in Childhood study, the prevalence of current asthma, allergic rhinoconjunctivitis, and atopic eczema in 2006 was 7.9%, 6.5%, and 10.1% among children aged 6-7 and 8.4%, 15.5%, and 7.75% among children aged 13-14 yr. University education in this field is provided by the Postgraduate Schools of Pediatrics and those of Allergology and Clinical Immunology, as well as several annual Master courses. The Italian Society of Pediatric Allergology and Immunology (SIAIP) was founded in 1996 and counts about 1000 members. SIAIP promotes evidence-based management of allergic children and disseminates information to patients and their families through a quite innovative website and the National Journal 'Rivista Italiana di Allergologia Pediatrica'. In the last decade, four major regional, inter-regional, and national web-based networks have been created to link pediatric allergy centers and to share their clinical protocols and epidemiologic data. In addition, National Registers of Primary Immune-deficiencies and on Pediatric HIV link all clinical excellence centers. Research projects in the field of pediatric allergy and immunology are founded by the Italian Ministry of Education, University and Research (MIUR) and by the National Research Council (CNR), but the overall investments in this research area are quite low. Only a handful Italian excellence centers participate in European Projects on Pediatric Allergy and Immunology within the 7th Framework Program. The European Academy of Allergy and Clinical Immunology currently hosts two Italians in its Executive Committee (EC) and one in the EC of the Pediatric Section; moreover, major European Academy of Allergy and Clinical Immunology meetings and courses in the area of pediatrics (e.g., PAAM, Venice, 2009) have been held in Italy in the last 3 yr.

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.

The effects of aging on the neural correlates of subjective and objective recollection.

PubMed

Duarte, Audrey; Henson, Richard N; Graham, Kim S

2008-09-01

High-functioning older adults can exhibit normal recollection when measured subjectively, via "remember" judgments, but not when measured objectively, via source judgments, whereas low-functioning older adults exhibit impairments for both measures. A potential explanation for this is that typical subjective and objective tests of recollection necessitate different processing demands, supported by distinct brain regions, and that deficits in these tests are observed according to the degree of age-related changes in these regions. Here, we used event-related functional magnetic resonance imaging to measure the effects of aging on neural correlates of subjective and objective measures of recollection, in young, high-functioning (Old-High) and low-functioning (Old-Low) older adults. Behaviorally, the Old-High group showed intact subjective ("remember" judgments) but impaired objective recollection (for 1 of 2 spatial or temporal sources), whereas the Old-Low group was impaired on both measures. Imaging data showed changes in parietal subjective recollection effects in the Old-Low group and in lateral frontal objective recollection effects in both older adult groups. Our results highlight the importance of examining performance variability in older adults and suggest that differential effects of aging on brain regions are associated with different patterns of performance on tests of subjective and objective recollection.

Headaches are common in the pediatric population, and increase in prevalence with age. The abortive medications currently used have a number of potential side effects. Sodium valproate (VPA) has been shown to be effective for acute treatment in the adult population, but no data exist in the pediatric population. The objective of this study was to evaluate the effectiveness of VPA for acute pediatric headache in the emergency department. This was a retrospective case series of all patients <19 years of age treated in the pediatric emergency department (PED) at two tertiary care pediatric hospitals and with a final diagnosis of migraine or headache who received parenteral VPA. Data collected included patient demographics, pain reduction, length of stay, and final disposition. From July 2010 to February 2014, there were 16 patients who received VPA for acute headache in the PED; 4 were excluded. Eighty-three percent were discharged home. Mean length of stay in the PED before VPA was 395 min, and 120 min after VPA administration. Patients achieved a 17% mean pain score reduction before VPA and approximately an additional 40% mean pain reduction after VPA infusion. VPA appears to be an effective agent for acute pediatric headache in this small series. Patients responded well to VPA in a relatively short amount of time. Further studies are needed to evaluate its effectiveness in combination with other first-line medications or as a single agent. Copyright © 2015 Elsevier Inc. All rights reserved.

New Antiretroviral Therapies for Pediatric HIV Infection

Human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome affect millions of children worldwide. The development of antiretroviral therapy has significantly improved the morbidity and mortality of pediatric patients infected with HIV. Currently, 4 classes of antiretroviral agents exist: nucleoside / nucleotide reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, protease inhibitors, and entry inhibitors. A total of 21 single-entity antiretroviral agents and 4 co-formulated antiretroviral products hold Food and Drug Administration (FDA) approval for treatment of HIV-1 infection. However, not all of these agents are indicated for use in patients less than 18 years of age. Since the year 2000, 7 new antiretroviral agents (atazanavir, emtricitabine, enfuvirtide, fosamprenavir, lopinavir/ritonavir, tenofovir, and tipranavir) have been approved by the FDA for use in adult patients as part of combination therapy for the treatment of HIV-1 infection. Although only 3 of these newer agents (emtricitabine, enfuvirtide, and lopinavir/ritonavir) are currently FDA approved for use in pediatric patients, pediatric clinical studies of the other 4 new agents are currently underway. The purpose of this article is to review these 7 new antiretroviral agents and describe their roles in the treatment of pediatric HIV infection. For each drug, the following information will be addressed: FDA-approved indication and age groups, clinical efficacy, pharmacokinetics, adverse drug reactions, clinically relevant drug interactions, pediatric and adult dosing, dosage forms, administration, and place in the treatment of pediatric HIV infection.

Biomarkers for oxidative stress: clinical application in pediatric medicine.

PubMed

Tsukahara, Hirokazu

2007-01-01

Loads of reactive oxygen species (ROS), including superoxide anion and nitric oxide, that overburden antioxidant systems induce oxidative stress in the body. Major cellular targets of ROS are membrane lipids, proteins, nucleic acids, and carbohydrates. Circumstantial evidence suggests that ROS play a crucial role in the initiation and progression of various diseases in children and adolescents. The involvement of ROS and oxidative stress in pediatric diseases is an important concern, but oxidative stress status in young subjects and appropriate methods for its measurement remain to be defined. Recently, specific biomarkers for oxidative damage and antioxidant defense have been introduced into the field of pediatric medicine. This review is intended to provide an overview of clinical applications of oxidative stress biomarkers in the field of pediatric medicine. First, this review presents the biochemistry and pathophysiology of ROS and antioxidant defense systems. Second, it presents a list of clinically applicable biomarkers, along with pediatric diseases in which enhanced oxidative stress might be involved. The discussion emphasizes that several reliable biomarkers are easily measurable using enzyme-linked immunosorbent assay. Third, this review presents age-related reference normal ranges of oxidative stress biomarkers, including urinary acrolein-lysine, 8-hydroxy-2'-deoxyguanosine, nitrite/nitrate, and pentosidine, and the changes of the parameters in several clinical conditions, including atopic dermatitis and diabetes mellitus. New and interesting data on oxidative stress and antioxidant defenses in neonatal biology are also presented. Fourth, this review discusses the ever-accumulating body of data linking oxidative stress to disturbances of the nitric oxide system and vascular endothelial activation/dysfunction. Finally, this review describes the reported clinical trials that have evaluated the efficacy of antioxidants for oxidative-stress related diseases

Although sleep is important for physical and psychological health, no research has assessed the sleep of children in a pediatric ICU and the factors that affect sleep. To observe the sleep of children in a pediatric ICU and to determine the relationship of noise, light, contact with caregivers, parental presence, and severity of illness to the sleep obtained by children in a pediatric ICU during a 10-hour night. At 5-minute intervals from 8 PM until 6 AM, a convenience sample of nine patients was observed. Sleep state, noise and light levels, contact with caregivers, and parental presence were recorded. Severity of illness was measured on admission and within 26 hours of data collection. Subjects slept for a mean total of 4.7 hours (SD = 0.49) during the 10-hour night, interrupted by a mean of 9.8 awakenings (SD = 2.48). The mean length of a sleep episode was only 27.6 minutes (SD = 25.85). Mean noise level was 55.1 dB(A) (SD = 6.82), with sudden, sharp elevations of up to 90 dB(A). Probit analysis indicated that noise, light, and contact with caregivers were significant predictors of sleep. Parental presence and severity of illness were not. Patients in the pediatric ICU sleep significantly less than is normal for children of the same ages, and their patterns of sleep are seriously disturbed. Because noise, light, and contact with caregivers are significant predictors of sleep state, health professionals can use these findings to structure the environment and the care they give to promote the sleep of critically ill children.

Appendicitis is the most common indication for emergency pediatric surgery and its most significant complication is perforation. Perforated appendicitis (PA) may be managed conservatively, whereas non-perforated appendicitis (NP) is managed surgically. Recent studies have shown that ultrasound (US) is effective for differentiating between PA and NP, and does not expose pediatric patients to ionizing radiation. The purpose of this study is to enhance the accuracy of differentiation with a novel scoring system based on clinical, laboratory, and US findings. This retrospective study included 243 patients aged 2-17 years who presented between 2006 and 2013 with surgically proven appendicitis, of whom 60 had perforation. Clinical and laboratory data were collected and US images evaluated by a pediatric radiologist. To create the scoring system, point values were assigned to each parameter. A randomly selected training sample of 137 subjects was used to create a scoring prediction model. The model was tested on the remaining 106 patients. Scores of ≥6, ≥11, and ≥15 yielded specificities of 64, 91, and 99%, and sensitivities of 96, 61, and 29%, respectively (p < 0.001). We have designed a scoring system incorporating clinical, laboratory, and sonographic findings which can differentiate PA from NP with high specificity.

Pediatric oncology in Turkey.

The survival of children with cancer has increased dramatically in the last decades, as a result of advances in diagnosis, treatment and supportive care. Each year in Turkey, 2500-3000 new childhood cancer cases are expected. According to the Turkish Pediatric Oncology Group and Turkish Pediatric Hematology Societies Registry, about 2000 new pediatric cancer cases are reported each year. The population in Turkey is relatively young. One fourth of the population is younger than 15 years of age. According to childhood mortality, cancer is the fourth cause of death (7.2%) after infections, cardiac deaths and accidents. The major cancers in children in Turkey are leukemia (31%), lymphoma (19%), central nervous system (CNS) neoplasms (13%), neuroblastomas (7%), bone tumors (6.1%), soft tissue sarcomas (6%), followed by renal tumors, germ cell tumors, retinoblastoma, carcinomas-epithelial neoplasms, hepatic tumors and others. Lymphomas rank second in frequency as in many developing countries in contrast to West Europe or USA, where CNS neoplasms rank second in frequency. The seven-year survival rate in children with malignancies in Turkey is 65.8%. The history of modern Pediatric Oncology in Turkey dates back to the 1970's. Pediatric Oncology has been accepted as a subspecialty in Turkey since 1983. Pediatric Oncologists are all well trained and dedicated. All costs for the diagnosis and treatment of children with cancer is covered by the government. Education and infrastructure for palliative care needs improvement.

Alopecia areata (AA) is a non-scarring autoimmune disease of the hair follicle that can present at any age. Pediatric cases are commonly seen in a dermatology clinic, and management can potentially be challenging, with a small proportion of cases experiencing a chronic relapsing course marked by distressing hair loss that can bring about significant psychosocial morbidity. We review the established treatments for pediatric alopecia areata, alongside second and third line therapies that have shown to be efficacious. We also offer a treatment algorithm as a guide to the treatment of pediatric AA. PMID:23248364

Significant knowledge deficits exist regarding sports injuries in the young child. Children continue to engage in physically demanding, organized sports to a greater extent despite the lack of physical readiness, predisposing themselves to injury. To evaluate sports injuries sustained in very young children (5-12 years) versus their older counterparts (13-17 years) with regard to the type and location of injuries, severity, and diagnosis. Cross-sectional study; Level of evidence, 3. A retrospective chart review was performed on a 5% random probability sample (final N = 2133) of 5- to 17-year-old patients treated for sports injuries in the Division of Sports Medicine at a large, academic pediatric medical center between 2000 and 2009. Using descriptive statistics, correlates of injuries by age group, injury type, and body area are shown. Five- to 12-year-old patients differed in key ways from older patients. Children in this category sustained injuries that were more often traumatic in nature and more commonly of the upper extremity. Older patients (13-17 years) were more likely to be treated for injuries to the chest, hip/pelvis, and spine. A greater proportion of the older children were treated for overuse injuries, as compared with their younger counterparts (54.4% vs. 49.2%, respectively), and a much larger proportion of these injuries were classified as soft tissue injuries as opposed to bony injuries (37.9% vs. 26.1%, respectively). Injury diagnosis differed between the 2 age groups. The 13- to 17-year age group sustained more anterior cruciate ligament injuries, meniscal tears, and spondylolysis, while younger children were diagnosed with fractures, including physeal fractures, apophysitis, and osteochondritis dissecans. The 5- to 12-year-old patients treated for spine injuries were disproportionately female (75.8%); most of these injuries were overuse (78.8%) and bony (60.6%); over one third of the youngest children were diagnosed with spondylolysis.

Although general definitions of the sepsis continuum have been published for adults, no such work has been done for the pediatric population. Physiologic and laboratory variables used to define the systemic inflammatory response syndrome (SIRS) and organ dysfunction require modification for the developmental stages of children. An international panel of 20 experts in sepsis and clinical research from five countries (Canada, France, Netherlands, United Kingdom, and United States) was convened to modify the published adult consensus definitions of infection, sepsis, severe sepsis, septic shock, and organ dysfunction for children. Consensus conference. This document describes the issues surrounding consensus on four major questions addressed at the meeting: a) How should the pediatric age groups affected by sepsis be delineated? b) What are the specific definitions of pediatric SIRS, infection, sepsis, severe sepsis, and septic shock? c) What are the specific definitions of pediatric organ failure and the validity of pediatric organ failure scores? d) What are the appropriate study populations and study end points required to successfully conduct clinical trials in pediatric sepsis? Five subgroups first met separately and then together to evaluate the following areas: signs and symptoms of sepsis, cell markers, cytokines, microbiological data, and coagulation variables. All conference participants approved the final draft of the proceedings of the meeting. Conference attendees modified the current criteria used to define SIRS and sepsis in adults to incorporate pediatric physiologic variables appropriate for the following subcategories of children: newborn, neonate, infant, child, and adolescent. In addition, the SIRS definition was modified so that either criteria for fever or white blood count had to be met. We also defined various organ dysfunction categories, severe sepsis, and septic shock specifically for children. Although no firm conclusion was made regarding

2012-03-01

Nonoperative management (NOM) of blunt splenic injuries has become the standard of care in hemodynamically stable children. This study compares the management of these injuries between pediatric and nonpediatric hospitals in Canada. Data were obtained from the Canadian Institute of Health Information trauma database on all patients aged 2 to 16 years, admitted to a Canadian hospital with a diagnosis of splenic injury between May 2002 and April 2004. Variables included age, sex, associated major injuries, splenic procedures, intensive care unit (ICU) admissions, blood transfusions, and length of stay. Hospitals were coded as pediatric or nonpediatric. Univariate analysis and logistic regression were used to determine associations between hospital type and outcomes. Of 1284 cases, 654 were managed at pediatric hospitals and 630 at nonpediatric centers. Patients at pediatric centers tended to be younger and more likely to have associated major injuries. Controlling for covariates, including associated major injuries, patients managed at pediatric centers were less likely to undergo splenectomy compared with those managed at nonpediatric centers (odds ratio [OR], 0.2; 95% confidence interval, 0.1-0.4). The risk of receiving blood products, admission to the ICU, and staying in hospital for more than 5 days was associated only with having associated major injuries. Even in the presence of other major injuries, successful NOM of blunt splenic injuries occurs more frequently in pediatric hospitals in Canada. This has policy relevance regarding education of adult surgeons about the appropriateness of NOM in children and developing guidelines on appropriate regional triaging of pediatric patients with splenic injury in Canada.

Subjective age is an important correlate of health, well-being, and longevity. So far, little is known about short-term variability in subjective age and the circumstances under which individuals feel younger/older in daily life. This study examined whether (a) older adults' felt age fluctuates on a day-to-day basis, (b) daily changes in health, stressors, and affect explain fluctuations in felt age, and (c) the daily associations between felt age and health, stressors, or affect are time-ordered. Using an eight-day daily diary approach, N = 43 adults (60-96 years, M = 74.65, SD = 8.19) filled out daily questionnaires assessing subjective age, health, daily stressors, and affect. Data were analysed using multilevel modelling. Subjective age, health, daily stressors, affect. Intra-individual variability in felt age was not explained by time but by short-term variability in other variables. Specifically, on days when participants experienced more than average health problems, stress, or negative affect they felt older than on days with average health, stress, or negative affect. No time-ordered effects were found. Bad health, many stressors, and negative affective experiences constitute circumstances under which older adults feel older than they typically do. Thus, daily measures of subjective age could be markers of health and well-being.

Diagnosis of pediatric neuropsychiatric disorders such as unipolar depression is largely based on clinical judgment - without objective biomarkers to guide diagnostic process and subsequent therapeutic interventions. Neuroimaging studies have previously reported average group-level neuroanatomical differences between patients with pediatric unipolar depression and healthy controls. In the present study, we investigated the utility of multiple neuromorphometric indices in distinguishing pediatric unipolar depression patients from healthy controls at an individual subject level. We acquired structural T1-weighted scans from 25 pediatric unipolar depression patients and 26 demographically matched healthy controls. Multiple neuromorphometric indices such as cortical thickness, volume, and cortical folding patterns were obtained. A support vector machine pattern classification model was 'trained' to distinguish individual subjects with pediatric unipolar depression from healthy controls based on multiple neuromorphometric indices and model predictive validity (sensitivity and specificity) calculated. The model correctly identified 40 out of 51 subjects translating to 78.4% accuracy, 76.0% sensitivity and 80.8% specificity, chi-square p-value = 0.000049. Volumetric and cortical folding abnormalities in the right thalamus and right temporal pole respectively were most central in distinguishing individual patients with pediatric unipolar depression from healthy controls. These findings provide evidence that a support vector machine pattern classification model using multiple neuromorphometric indices may qualify as diagnostic marker for pediatric unipolar depression. In addition, our results identified the most relevant neuromorphometric features in distinguishing PUD patients from healthy controls. Copyright © 2015 Elsevier Ltd. All rights reserved.

To evaluate the health-related quality of life (HRQL) in pediatric leprosy patients. A cross-sectional study included 47 leprosy patients and 45 healthy subjects. The HRQL was measured by Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0), and evaluated physical, emotional, social and school domains. The leprosy patients were classified by Ridley and Jopling classification criteria and assessed according to clinical musculoskeletal manifestations, laboratory and radiographic examinations. The median of current age was similar in leprosy patients and controls [12(6-18) vs. 15(5-18)years, p = 0.384], likewise the frequencies of female gender (p = 0.835) and middle/lower Brazilian socio-economic classes (p = 1.0). The domain school activities according the child-self report was significantly lower in leprosy patients compared to controls in the age group of 13-18 years [75(45-100) vs. 90(45-100), p = 0.021]. The other domains were alike in both groups (p > 0.05). At least one musculoskeletal manifestation (arthralgia, arthritis and/or myalgia) was observed in 15% of leprosy patients and none in controls (p = 0.012). Further comparison between all leprosy patients showed that the median of the physical capacity domain [81.25(50-100) vs. 98.44(50-100), p = 0.036] and school activities domain by child-self report [60(50-85) vs. 80(45-100), p = 0.042] were significantly lower in patients with musculoskeletal manifestations compared to patients without these manifestations. No differences were evidenced between the other HRQL parameters in both groups, reported by patients and parents (p > 0.05). Reduced physical capacity and school activities domains were observed in pediatric leprosy patients with musculoskeletal manifestations. Copyright © 2015 Elsevier Editora Ltda. All rights reserved.

Pediatric nutrition risk screening tools are not routinely implemented throughout many hospitals, despite prevalence studies demonstrating malnutrition is common in hospitalized children. Existing tools lack the simplicity of those used to assess nutrition risk in the adult population. This study reports the accuracy of a new, quick, and simple pediatric nutrition screening tool (PNST) designed to be used for pediatric inpatients. The pediatric Subjective Global Nutrition Assessment (SGNA) and anthropometric measures were used to develop and assess the validity of 4 simple nutrition screening questions comprising the PNST. Participants were pediatric inpatients in 2 tertiary pediatric hospitals and 1 regional hospital. Two affirmative answers to the PNST questions were found to maximize the specificity and sensitivity to the pediatric SGNA and body mass index (BMI) z scores for malnutrition in 295 patients. The PNST identified 37.6% of patients as being at nutrition risk, whereas the pediatric SGNA identified 34.2%. The sensitivity and specificity of the PNST compared with the pediatric SGNA were 77.8% and 82.1%, respectively. The sensitivity of the PNST at detecting patients with a BMI z score of less than -2 was 89.3%, and the specificity was 66.2%. Both the PNST and pediatric SGNA were relatively poor at detecting patients who were stunted or overweight, with the sensitivity and specificity being less than 69%. The PNST provides a sensitive, valid, and simpler alternative to existing pediatric nutrition screening tools such as Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP), Screening Tool Risk on Nutritional status and Growth (STRONGkids), and Paediatric Yorkhill Malnutrition Score (PYMS) to ensure the early detection of hospitalized children at nutrition risk. © 2014 American Society for Parenteral and Enteral Nutrition.

Ethical issues in pediatric emergency mass critical care.

2011-11-01

As a result of recent events, including natural disasters and pandemics, mass critical care planning has become a priority. In general, planning involves limiting the scope of disasters, increasing the supply of medical resources, and allocating scarce resources. Entities at varying levels have articulated ethical frameworks to inform policy development. In spite of this increased focus, children have received limited attention. Children require special attention because of their unique vulnerabilities and needs. In May 2008, the Task Force for Mass Critical Care published guidance on provision of mass critical care to adults. Acknowledging that the critical care needs of children during disasters were unaddressed by this effort, a 17-member Steering Committee, assembled by the Oak Ridge Institute for Science and Education with guidance from members of the American Academy of Pediatrics, convened in April 2009 to determine priority topic areas for pediatric emergency mass critical care recommendations.Steering Committee members established subgroups by topic area and performed literature reviews of MEDLINE and Ovid databases. Draft documents were subsequently developed and revised based on the feedback from the Task Force. The Pediatric Emergency Mass Critical Care Task Force, composed of 36 experts from diverse public health, medical, and disaster response fields, convened in Atlanta, GA, on March 29-30, 2010. This document reflects expert input from the Task Force in addition to the most current medical literature. The Ethics Subcommittee recommends that surge planning seek to provide resources for children in proportion to their percentage of the population or preferably, if data are available, the percentage of those affected by the disaster. Generally, scarce resources should be allocated on the basis of need, benefit, and the conservation of resources. Estimates of need, benefit, and resource utilization may be more subjective or objective. While the

The original Pediatric Sepsis Biomarker Risk Model and revised (Pediatric Sepsis Biomarker Risk Model-II) biomarker-based risk prediction models have demonstrated utility for estimating baseline 28-day mortality risk in pediatric sepsis. Given the paucity of prediction tools in pediatric acute respiratory distress syndrome, and given the overlapping pathophysiology between sepsis and acute respiratory distress syndrome, we tested the utility of Pediatric Sepsis Biomarker Risk Model and Pediatric Sepsis Biomarker Risk Model-II for mortality prediction in a cohort of pediatric acute respiratory distress syndrome, with an a priori plan to revise the model if these existing models performed poorly. Prospective observational cohort study. University affiliated PICU. Mechanically ventilated children with acute respiratory distress syndrome. Blood collection within 24 hours of acute respiratory distress syndrome onset and biomarker measurements. In 152 children with acute respiratory distress syndrome, Pediatric Sepsis Biomarker Risk Model performed poorly and Pediatric Sepsis Biomarker Risk Model-II performed modestly (areas under receiver operating characteristic curve of 0.61 and 0.76, respectively). Therefore, we randomly selected 80% of the cohort (n = 122) to rederive a risk prediction model for pediatric acute respiratory distress syndrome. We used classification and regression tree methodology, considering the Pediatric Sepsis Biomarker Risk Model biomarkers in addition to variables relevant to acute respiratory distress syndrome. The final model was comprised of three biomarkers and age, and more accurately estimated baseline mortality risk (area under receiver operating characteristic curve 0.85, p < 0.001 and p = 0.053 compared with Pediatric Sepsis Biomarker Risk Model and Pediatric Sepsis Biomarker Risk Model-II, respectively). The model was tested in the remaining 20% of subjects (n = 30) and demonstrated similar test characteristics. A validated, biomarker

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.

Management of colonic injuries (colostomy [CO] versus primary anastomosis [PA]) among pediatric patients remains controversial. The aim of this study was to assess outcomes in pediatric trauma patient with colonic injury undergoing operative intervention. The National Trauma Data Bank (2011-2012) was queried including patients with isolated colonic injury undergoing exploratory laparotomy with PA or CO with age ≤18 y. Missing value analysis was performed. Patients were stratified into two groups: PA and CO. Outcome measures were mortality, in-hospital complications, and hospital length of stay. Multivariate regression analysis was performed. A total of 1151 patients included. Mean ± standard deviation age was 11.61 ± 2.8 y, and median [IQR] Injury Severity Score was 12 [8-16]; 39% (n = 449) of the patients had CO, and 35.6% (n = 410) were managed in pediatric trauma centers (PC). Patients with CO had a higher Injury Severity Score (P < 0.001), a trend toward lower blood pressure (P = 0.40), and an older age (P < 0.001). There was no difference in mortality between the PA and CO groups. However, patients who underwent PA had a shorter length of stay (P < 0.001) and lower in-hospital complications (P < 0.001). A subanalysis shows that, after controlling for all confounding factors, patients managed in PC were 1.2 times (1.2 [1.1-2.1], P = 0.04) more likely to receive a CO than those patients managed in adult trauma centers (AC). Moreover, there was no difference in mortality between the AC and the PC (P = 0.79). Our data demonstrate no difference in mortality in pediatric trauma patients with colonic injury who undergo primary repair or CO. However, adult trauma centers had lower rates of CO performed as compared to a similar cohort of patients managed in pediatric trauma centers. Further assessment of the reasons underlying such differences will help improve patient outcomes. Copyright © 2017 Elsevier Inc. All rights reserved.

Nasopharyngeal carcinoma (NPC) is very rare in childhood. It differs from its adult counterpart in the prevalence of the nonkeratinizing, undifferentiated subtype and by an advanced clinical stage at onset and better chances of survival. The risk of long-term treatment-related toxicity also may be a more important issue in younger individuals. A prospective chemoradiotherapy protocol for pediatric NPC was started in Italy in 2000 within the framework of the Rare Tumors in Pediatric Age (TREP) project. Three courses of cisplatin/5-fluorouracil induction chemotherapy were followed by radiotherapy (doses up to 65 grays) with concomitant cisplatin. Forty-six patients (ages 9-17 years) were considered eligible for the study over a 10-year period. The ratio of observed to expected cases based on epidemiological data was approximately 1 for both children and adolescents. All but 1 patient had lymph node involvement, and 5 patients had distant metastases. The rate of response to primary chemotherapy was 90%. The 5-year overall and progression-free survival rates were 80.9% and 79.3%, respectively (median follow-up, 62 months). The only statistically significant prognostic variable was the presence or absence of distant metastases. A 65% incidence of late sequelae was reported. This study demonstrates the feasibility and efficacy of a prospective protocol even for such rare tumors as pediatric NPC. The use of lower radiotherapy doses than those used in adults did not affect locoregional failure rates. Long-term follow-up will be needed to obtain more information on both survival and treatment sequelae. The next objective will be to establish broader, international prospective cooperation schemes.

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

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.

Witt, Cordelie E; Arbabi, Saman; Nathens, Avery B; Vavilala, Monica S; Rivara, Frederick P

2017-04-01

The implications of childhood obesity on pediatric trauma outcomes are not clearly established. Anthropomorphic data were recently added to the National Trauma Data Bank (NTDB) Research Datasets, enabling a large, multicenter evaluation of the effect of obesity on pediatric trauma patients. Children ages 2 to 19years who required hospitalization for traumatic injury were identified in the 2013-2014 NTDB Research Datasets. Age and gender-specific body mass indices (BMI) were calculated. Outcomes included injury patterns, operative procedures, complications, and hospital utilization parameters. Data from 149,817 pediatric patients were analyzed; higher BMI percentiles were associated with significantly more extremity injuries, and fewer injuries to the head, abdomen, thorax and spine (p values <0.001). On multivariable analysis, higher BMI percentiles were associated with significantly increased likelihood of death, deep venous thrombosis, pulmonary embolus and pneumonia; although there was no difference in risk of overall complications. Obese children also had significantly longer lengths of stay and more frequent ventilator requirement. Among children admitted after trauma, increased BMI percentile is associated with increased risk of death and potentially preventable complications. These findings suggest that obese children may require different management than nonobese counterparts to prevent complications. Level III; prognosis study. Copyright © 2017 Elsevier Inc.

Studies on methicillin-resistant Staphylococcus aureus (MRSA) infections have typically focused on pediatric and adult populations at urban tertiary care hospitals. Limited data exist on MRSA rates in skin and soft tissue infections (SSTI) in suburban community hospital pediatric emergency departments (PED). To describe the prevalence of MRSA in SSTIs in a contemporary suburban community hospital PED population. Patients 0-21 years old with SSTI wound cultures who were seen at our PED from 2003-2007 were studied. Data analyzed included type of infection (abscess vs. non-abscess), site of infection, and culture results. Chi-squared and t-tests were used as appropriate; p < 0.05 was considered significant. During the study period, 204 cultures were obtained for SSTIs, 11 of which were contaminants. The subjects had a mean age of 12.9 years (SD 6.8 years); 60% were male. The prevalence of MRSA was 27%; MRSA was present in 30% of abscesses vs. 2.2% of non-abscess SSTI (p < 0.005). By year, the prevalence of MRSA was 10% in 2003, 31% in 2004, 33% in 2005, 31% in 2006, and 29% in 2007. No differences between MRSA and non-MRSA infections were present for gender, age, or site of infection. At our suburban community hospital pediatric ED, MRSA was present in 30% of all SSTI wound cultures; MRSA was unlikely with non-abscess SSTI. Our overall MRSA prevalence data among SSTIs are consistent with previously published reports in pediatric ED populations but may be less than those reported in the adult literature.

Pediatric dog bite injuries are common and vary in severity. We sought to characterize predisposing factors, required interventions, and morbidity. A prospective clinical database at a level one pediatric trauma center was reviewed for dog bite injuries over 74 consecutive months ending December 2013. This included all patients brought in by ambulance and/or seen by the trauma team. Of 650 dog bite incidents, 282 met the criteria for inclusion in the trauma database. Median age was 5 years (range, 2 months to 17 years) and 55% (154/282) of patients were male. Pit bulls were most frequently responsible, accounting for 39% (83/213) of incidents in which dog breed was documented. Fifty-three percent (150/282) of dogs belonged to the patient's immediate or extended family. Sixty-nine percent (194/282) of patients required operative intervention: 76% laceration repairs, 14% tissue transfers, and 2% neurosurgical interventions. The most severe injuries were depressed skull fractures, intracranial hemorrhage, laryngotracheal transection, and bilateral orchiectomy. Median length of stay was 1 day (range, 0 to 25 days). There were no mortalities. Pediatric dog bites span a wide range of ages, frequently require operative intervention, and can cause severe morbidity. Dog familiarity did not confer safety, and in this series, Pit bulls were most frequently responsible. These findings have great relevance for child safety. Pediatric dog bites are common and can vary in severity from superficial wounds to life-threatening injuries. Dog familiarity may confer a false sense of safety. A national dog bite prevention and education campaign should be developed with the goal of decreasing the incidence of pediatric dog bites. Copyright © 2015 Elsevier Inc. All rights reserved.

Exercise training and physical activity (PA) have substantial vascular and cardiac health benefits. Ikaria Island has been recognised as having one of the highest longevity rates worldwide and a high percentage of healthy ageing. We examined the relationship between endothelial function and levels of habitual PA to evaluate the factors related to healthy ageing in this population. The study was conducted on a subgroup population of the IKARIA study consisting of 185 middle-aged (40-65 years) and 142 elderly subjects (66-91 years). Endothelial function was evaluated by ultrasound measurement of flow-mediated dilatation (FMD). PA was evaluated using the shortened version of the self-reported International Physical Activity Questionnaire (IPAQ). Subjects in the low PA group (<500 MET/ min/week) were considered as physically inactive and the rest as active. In the overall study population FMD was inversely associated with age (r=-0.24, p<0.001) and middle-aged subjects had higher FMD compared with the elderly (6.26 ± 3.31% vs. 5.21 ± 2.95%, p=0.003). Multiple linear regression analysis revealed that among middle-aged subjects the physically active had higher FMD compared with the physically inactive. Physically active subjects in the middle-aged group showed higher FMD compared with the physically active elderly (p=0.008). However, there was no difference in FMD values between middle-aged inactive subjects and the elderly physically active (p=NS). The present study revealed that increased PA was associated with improved endothelial function in middle-aged subjects and that PA in elderly subjects can ameliorate the devastating effects of ageing on arterial wall properties.

Policy statement--pediatric organ donation and transplantation.

PubMed

2010-04-01

Pediatric organ donation and organ transplantation can have a significant life-extending benefit to the young recipients of these organs and a high emotional impact on donor and recipient families. Pediatricians, pediatric medical specialists, and pediatric transplant surgeons need to be better acquainted with evolving national strategies that involve organ procurement and organ transplantation to help acquaint families with the benefits and risks of organ donation and transplantation. Efforts of pediatric professionals are needed to shape public policies to provide a system in which procurement, distribution, and cost are fair and equitable to children and adults. Major issues of concern are availability of and access to donor organs; oversight and control of the process; pediatric medical and surgical consultation and continued care throughout the organ-donation and transplantation process; ethical, social, financial, and follow-up issues; insurance-coverage issues; and public awareness of the need for organ donors of all ages.

This study showed a retrospective analysis of the etiology, incidence and treatment of maxillofacial injuries in a pediatric and adolescent population of the State of Sao Paulo. We analyzed 2986 medical records of victims of facial trauma under 18 years, treated between 1999 and 2008 by the Department of Oral and Maxillofacial Surgery, Piracicaba Dental School, University of Campinas, Sao Paulo - Brazil. During this period, 757 patients under 18 were victims of maxillofacial trauma, of which, 112 patients had 139 lines of fracture in the mandible. The most affected age group were male adolescents. The bicycle accidents constituted the main etiology (34.82%). The conservative treatment was used in 51% of cases, and 49% received surgical treatment. Only 5 cases of postoperative complications were identified. The incidence of trauma and mandible fractures in pediatric and adolescent patients was high in the area of study. Bicycle accidents and falls being the main etiological factors. The group of adolescents was most affected. The conservative and surgical treatment was used almost in the same proportion.

We developed a first-person serious game, PediatricSim, to teach and assess performances on seven critical pediatric scenarios (anaphylaxis, bronchiolitis, diabetic ketoacidosis, respiratory failure, seizure, septic shock, and supraventricular tachycardia). In the game, players are placed in the role of a code leader and direct patient management by selecting from various assessment and treatment options. The objective of this study was to obtain supportive validity evidence for the PediatricSim game scores. Game content was developed by 11 subject matter experts and followed the American Heart Association's 2011 Pediatric Advanced Life Support Provider Manual and other authoritative references. Sixty subjects with three different levels of experience were enrolled to play the game. Before game play, subjects completed a 40-item written pretest of knowledge. Game scores were compared between subject groups using scoring rubrics developed for the scenarios. Validity evidence was established and interpreted according to Messick's framework. Content validity was supported by a game development process that involved expert experience, focused literature review, and pilot testing. Subjects rated the game favorably for engagement, realism, and educational value. Interrater agreement on game scoring was excellent (intraclass correlation coefficient = 0.91, 95% confidence interval = 0.89-0.9). Game scores were higher for attendings followed by residents then medical students (Pc < 0.01) with large effect sizes (1.6-4.4) for each comparison. There was a very strong, positive correlation between game and written test scores (r = 0.84, P < 0.01). These findings contribute validity evidence for PediatricSim game scores to assess knowledge of pediatric emergency medicine resuscitation.

Perception of pediatric neurology among non-neurologists.

Pediatric neurology is considered a relatively new and evolving subspecialty. In Saudi Arabia, neurologic disorders in children are common, and the demand for trained pediatric neurologists is strong. The aim was to study the perception of the pediatric neurology specialty among practicing generalists and their referral practices. Attendees of a symposium on pediatric epilepsy comprehensive review for the generalist were included. A structured 25-item questionnaire was designed to examine their demographics, training, practice, and referral patterns. One hundred nineteen participants attended the symposium, and 90 (76%) questionnaires were returned. Attendees' ages were 22 to 70 years (mean 32 years), with 65.5% female physicians. There were 32% consultants, 51% trainees, and 17% students. Most physicians (67%) were practicing general pediatrics. Only 36% received a structured pediatric neurology rotation during training. Children with neurologic complaints constituted 28.5% of those seen in their practice, and they referred 32.5% of them to pediatric neurology. Only 32% were moderately or highly confident in making the diagnosis or providing the appropriate treatment. Those who received a structured pediatric neurology rotation felt more comfortable in their management (P = .03). Many physicians (38.5%) had no direct access to a pediatric neurologist for referrals. To conclude, pediatric neurologic disorders are common in daily practice. Most generalists did not receive a structured neurology rotation during their training and were not highly confident in diagnosing and treating these children. Given the limited number of pediatric neurologists, I highly recommend that generalists receive appropriate neurologic training.

The dorsolateral prefrontal cortex (DLPFC) plays an essential role in mood regulation and integration of cognitive functions that are abnormal in major depressive disorder (MDD). Few neuroimaging studies have evaluated the still maturing DLPFC in depressed children and adolescents. We conducted single voxel proton magnetic resonance spectroscopy ((1)H MRS) of the left DLPFC in 14 depressed children and adolescents (13.3 +/- 2.3 years old, 10 males) and 22 matched healthy controls (13.6 +/- 2.8 years old, 13 males). Depressed subjects had significantly lower levels of glycerophosphocholine plus phosphocholine (GPC + PC; or choline-containing compounds) and higher myo-inositol levels in the left DLPFC compared to healthy controls. In the depressed subjects, we found significant inverse correlations between glutamate levels and both duration of illness and number of episodes. In healthy controls there was a significant direct correlation between age and glutamine levels, which was not present in the patient group. Lower GPC + PC levels in pediatric MDD may reflect lower cell membrane content per volume in the DLPFC. Increased myo-inositol levels in MDD may represent a disturbed secondary messenger system. GPC + PC and myo-inositol abnormalities further demonstrate the involvement of DLPFC in pediatric MDD.

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.

Interactions between stereotype threat, subjective aging, and memory in older adults.

Marquet, Manon; Missotten, Pierre; Dardenne, Benoit; Adam, Stéphane

2017-12-08

This study examined whether the effects of stereotype threat on memory and subjective age were moderated by positive age stereotypes and self-perceptions of aging among older adults. Perceived threat as a mechanism underlying these effects was also explored. Results showed that stereotype threat (high vs. low threat) did not affect the dependent variables. Moreover, self-perceptions of aging did not moderate the effect of stereotype threat on the dependent variables. However, for people with more positive age stereotypes, older people under highthreat perceived more threat than people under low threat. This could be explained by an effect of age stereotypes in the high-threat group: the more positive age stereotypes held by participants, the more they perceived threat, which in turn decreased their memory performance and made them feel mentally older. We hypothesized that age group identity is stronger in people with more positive age stereotypes, which increase perceived threat.

Surgical management of pediatric urolithiasis

Pediatric urolithiasis poses a technical challenge to the urologist. A review of the recent literature on the subject was performed to highlight the various treatment modalities in the management of pediatric stones. A Medline search was used to identify manuscripts dealing with management options such as percutaneous nephrolithotomy, shock wave lithotripsy, ureteroscopy and cystolithotripsy in pediatric stone diseases. We also share our experience on the subject. Shock wave lithotripsy should be the treatment modality for renal stone less than 1cm or < 150 mm2 and proximal non-impacted ureteric stone less than 1 cm with normal renal function, no infection and favorable anatomy. Indications for PCNL in children are large burden stone more than 2cm or more than 150mm2 with or without hydronephrosis, urosepsis and renal insufficiency, more than 1cm impacted upper ureteric stone, failure of SWL and significant volume of residual stones after open surgery. Shock wave lithotripsy can be offered for more soft (< 900 HU on CT scan) renal stones between 1-2cm. Primary vesical stone more than 1cm can be tackled with percutaneous cystolithomy or open cystolithotomy. Open renal stone surgery can be done for renal stones with associated structural abnormalities, large burden infective and staghorn stones, large impacted proximal ureteric stone. The role of laparoscopic surgery for stone disease in children still needs to be explored. PMID:19718300

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

This paper was undertaken to review the experience at our institution with bilateral sequential lung transplantation for cystic fibrosis. Since 1989, 103 bilateral sequential lung transplants for cystic fibrosis have been performed (46 pediatric, 48 adult, 9 redo); the mean age was 21 +/- 10 years. Cardiopulmonary bypass was used in all but one pediatric (age <18) transplant, and in 15% of adults. Hospital mortality was 4.9%, with 80% of early deaths related to infection. Bronchial anastomotic complications occurred with equal frequency in the pediatric and the adult populations (7.3%). One- and 3-year actuarial survival are 84% and 61%, respectively (no significant difference between pediatric and adult age groups; average follow-up 2.1 +/- 1.6 years). Mean forced expiratory volume in 1 second increased from 25% +/- 9% before transplantation to 79% +/- 35% 1 year after transplantation. Acute rejection occurred 1.7 times per patient-year, with most episodes taking place within the first 6 months after transplantation. The need for treatment of lower respiratory tract infections occurred 1.2 times per patient in the first year after transplantation. Actuarial freedom from bronchiolitis obliterans was 63% at 2 years and 43% at 3 years. Redo transplantation was performed only in the pediatric population and was associated with an early mortality of 33%. Eight living donor transplants (four primary transplants, four redo transplants) were performed with an early survival of 87.5%. Patients with end-stage cystic fibrosis can undergo bilateral lung transplantation with morbidity and mortality comparable to that seen in pulmonary transplantation for other disease entities.

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.

To introduce and validate the pediatric ocular trauma score (POTS) - a mathematical model to predict visual outcome trauma in children with traumatic cataract METHODS: In this retrospective cohort study, medical records of consecutive children with traumatic cataracts aged 18 and below were retrieved and analysed. Data collected included age, gender, visual acuity, anterior segment and posterior segment findings, nature of surgery, treatment for amblyopia, follow-up, and final outcome was recorded on a precoded data information sheet. POTS was derived based on the ocular trauma score (OTS), adjusting for age of patient and location of the injury. Visual outcome was predicted using the OTS and the POTS and using receiver operating characteristic (ROC) curves. POTS predicted outcomes were more accurate compared to that of OTS (p = 0.014). POTS is a more sensitive and specific score with more accurate predicted outcomes compared to OTS, and is a viable tool to predict visual outcomes of pediatric ocular trauma with traumatic cataract.

Tuberculosis in childhood is clinically challenging, but it is a preventable and treatable disease. Risk factors depend on age and immunity status. The most common form of pediatric tuberculosis is pulmonary disease, which comprises more than half of the cases. Other forms make up the extrapulmonary tuberculosis that involves infection of the lymph nodes, central nervous system, gastrointestinal system, hepatobiliary tree, and renal and musculoskeletal systems. Knowledge of the imaging characteristics of pediatric tuberculosis provides clues to diagnosis. This article aims to review the imaging characteristics of common sites for extrapulmonary tuberculous involvement in children.

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.

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.

Accidental traumatic injury is the number 1 cause of morbidity and mortality in the pediatric population. In this study, we aim to prove that certain pediatric patients can be treated with good outcomes at an adult level 1 trauma center. Retrospective analysis using the Howard University Hospital trauma registry identified 71 patients treated at Howard University Hospital between the ages of 1 and 17 years old. Specific variables were identified and collected for each patient. The majority of pediatric traumas treated at Howard University Hospital between June 2004 and May 2005 had high survival rates (93%). The patients who did not survive (7%) included 3 patients who were dead on arrival and 2 who died shortly after arrival to the hospital. Certain pediatric populations who present with minor and/or isolated injuries can be treated in an adult level 1 trauma center with similar outcomes to treatment in a pediatric level 1 trauma center.

To examine the extent to which the theory of planned behavior (TPB) predicts academic clinicians' intent to treat pediatric obesity. A multi-disciplinary panel iteratively devised a Likert scale survey based on the constructs of the TPB applied to a set of pediatric obesity themes. A cross-sectional electronic survey was then administered to academic clinicians at tertiary care centers across Canada from January to April 2012. Descriptive statistics were used to summarize demographic and item agreement data. A hierarchical linear regression analysis controlling for demographic variables was conducted to examine the extent to which the TPB subscales predicted intent to treat pediatric obesity. A total of 198 physicians, surgeons, and allied health professionals across Canada (British Columbia, Alberta, Manitoba, Saskatchewan, Nova Scotia, Ontario and Quebec) completed the survey. On step 1, demographic factors accounted for 7.4% of the variance in intent scores. Together in step 2, demographic variables and TPB subscales predicted 56.9% of the variance in a measure of the intent to treat pediatric obesity. Perceived behavioral control, that is, confidence in one's ability to manage pediatric obesity, and subjective norms, congruent with one's context of practice, were the most significant predictors of the intent to treat pediatric obesity. Attitudes and barriers did not predict the intent to treat pediatric obesity in this context. Enhancing self-confidence in the ability to treat pediatric obesity and the existence of supportive treatment environments are important to increase clinician's intent to treat pediatric obesity.

Pediatric mandibular fractures.

In spite of curiosity, facial fractures, particularly mandibular fractures, in the pediatric age group embrace only a modest proportion of facial fractures that occur within the general population. Several large series report an overall incidence of approximately 1% of all facial bone fractures. A considerable volume of literature has been generated describing the pattern of injury and treatment modalities for pediatric facial bone fractures. At our institution, which is an extremely busy university-based regional trauma center, we have witnessed a persistent escalation in the number of patients requiring repair of their facial bone fractures. During the period of January 1989 through January 1990, we treated a total of 204 patients for repair of mandible fractures. An analysis of the records of this group revealed only 3 patients who were younger than 4 years of age and 2 additional patients younger than 8 years. There were another 10 patients 17 years and younger, for a total incidence of 0.08%. Additionally, we found that within this seemingly small group, there was a surprisingly high incidence of severe, associated injuries.

Introduction In 2007, the California signed legislation mandating a dental visit for all children entering kindergarten or first grade; no such mandate was made for physician visits. This study examines the impact of this policy change on the risk factors associated with obtaining pediatric dental and physician health care visits. Methods Every 2 years, California Health Interview Survey conducts a statewide survey on a representative community sample. This cross-sectional study took advantage of these data to conduct a "natural experiment" assessing the impact of this policy change on both pediatric physician and dental care visits in the past year. Samples included surveys of adults and children (ages 5-11) on years 2005 (n = 5096), 2007 (n = 4324) and 2009 (n = 4100). Results Although few changes in risk factors were noted in pediatric physician visits, a gradual decrease in risk factors was found in pediatric dental visits from 2005 to 2009. Report of no dental visit was less likely for: younger children (OR -0.81, CI 0.75-0.88), insured children (OR 0.34, CI 0.22-0.53), and children who had a physician's visit last year (OR 0.37, CI 0.25-0.53) in 2005. By 2007, absence of insurance was the only risk factor related to having no dental visit (OR 0.34, CI 0.19-0.61). By 2009, no a priori measured risk factors were associated with not having a dental visit for children aged 5-11 years. Conclusions A statewide policy mandating pediatric dental visits appears to have reduced disparities. A policy for medical care may contribute to similar benefits.

To document the clinical and paraclinical features of pediatric multiple sclerosis (MS) in Turkey. Data of MS patients with onset before age 18 years (n = 193) were collected from 27 pediatric neurology centers throughout Turkey. Earlier-onset (<12 years) and later-onset (≥12 years) groups were compared. There were 123 (63.7%) girls and 70 (36.3%) boys aged 4-17 years, median 14 years at disease onset. Family history of MS was 6.5%. The first presentation was polysymptomatic in 55.4% of patients, with brainstem syndromes (50.3%), sensory disturbances (44%), motor symptoms (33.2%), and optic neuritis (26.4%) as common initial manifestations. Nineteen children had facial paralysis and 10 had epileptic seizures at first attack; 21 (11%) were initially diagnosed with acute disseminated encephalomyelitis (ADEM). Oligoclonal bands were identified in 68% of patients. Magnetic resonance imaging revealed periventricular (96%), cortical/juxtacortical (64.2%), brainstem (63%), cerebellum (51.4%), and spinal cord (67%) involvement. Visual evoked potentials (VEP) were abnormal in 52%; serum 25-hydroxyvitamin D levels were low in 68.5% of patients. The earlier-onset group had a higher rate of infection/vaccination preceding initial attack, initial diagnosis of ADEM, longer interval between first 2 attacks, and more disability accumulating in the first 3 years of the disease. Brainstem and cerebellum are common sites of clinical and radiological involvement in pediatric-onset MS. VEP abnormalities are frequent even in patients without history of optic neuropathy. Vitamin D status does not appear to affect the course in early disease. MS beginning before 12 years of age has certain characteristics in history and course.

Pediatric heart allocation in Eurotransplant (ET) has evolved over the past decades to better serve patients and improve utilization. Pediatric heart transplants (HT) account for 6% of the annual transplant volume in ET. Death rates on the pediatric heart transplant waiting list have decreased over the years, from 25% in 1997 to 18% in 2011. Within the first year after listing, 32% of all infants (<12 months), 20% of all children aged 1-10 years, and 15% of all children aged 11-15 years died without having received a heart transplant. Survival after transplantation improved over the years, and in almost a decade, the 1-year survival went from 83% to 89%, and the 3-year rates increased from 81% to 85%. Improved medical management of heart failure patients and the availability of mechanical support for children have significantly improved the prospects for children on the heart transplant waiting list. © 2014 Steunstichting ESOT.

Among opinions issued by the Forensic Medicine Department, Medical Science University in Poznan, in the last six years, there are opinions concerning age estimation in child pornography materials. The issue subject to research is indicating persons under the age of 15 years in pornographic materials, since possession of pornographic materials featuring underage persons is considered a crime and is subject to article 202 of the Penal Code. The estimation of the age of teenagers based on secondary and tertiary sexual characteristics is increasingly more difficult and the available data in professional literature regarding the standard time of development differ among various authors of such studies. In the report, an attempt has been made at determining the agreement regarding different characteristics in the data included in the Tanner's scale, which has been modified to accommodate the research done on persons registered by electronic means. The modified scale, which up to now has been used in research of registered subjects in classified public prosecutors' materials, has been employed in children seen in a pediatric outpatient department. The goal has been a comparison of the outcome of the research to prove its usefulness so that in the future, the modified scale could be used as a research tool in estimation of age of persons appearing in pornography materials. medical forms of 205 children seen in a pediatric outpatient department, based on the scale created by the present authors us and later processed using Excel.

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.

After pediatric cardiac surgery, ventilation with high airway pressures can be detrimental to right ventricular function and pulmonary blood flow. Neurally adjusted ventilatory assist (NAVA) improves patient-ventilator interactions, helping maintain spontaneous ventilation. This study reports our experience with the use of NAVA in children after a cardiac surgery. We hypothesize that using NAVA in this population is feasible and allows for lower ventilation pressures. We retrospectively studied all children ventilated with NAVA (invasively or noninvasively) after undergoing cardiac surgery between January 2013 and May 2015 in our pediatric intensive care unit. The number and duration of NAVA episodes were described. For the first period of invasive NAVA in each subject, detailed clinical and ventilator data in the 4 h before and after the start of NAVA were extracted. 33 postoperative courses were included in 28 subjects with a median age of 3 [interquartile range (IQR) 1-12] months. NAVA was used invasively in 27 courses for a total duration of 87 (IQR 15-334) h per course. Peak inspiratory pressures and mean airway pressures decreased significantly after the start of NAVA (mean differences of 5.8 cm H 2 O (95% CI 4.1-7.5) and 2.0 cm H 2 O (95% CI 1.2-2.8), respectively, P < .001 for both). There was no significant difference in vital signs or blood gas values. NAVA was used noninvasively in 14 subjects, over 79 (IQR 25-137) h. NAVA could be used in pediatric subjects after cardiac surgery. The significant decrease in airway pressures observed after transition to NAVA could have a beneficial impact in this specific population, which should be investigated in future interventional studies.

The clinical utility of culture-independent testing of pediatric bronchoalveolar lavage (BAL) specimens is unknown. Additionally, the variability of the pediatric pulmonary microbiome with patient characteristics is not well understood. Study subjects were ≤22 years old and underwent BAL from May 2013 - July 2015 as part of clinical care. DNA extracted from BAL specimens was used for 16S rRNA gene-based (16S-based) microbiome analysis, and results compared to routine cultures from the same samples. Indices of microbial diversity and relative taxon abundances were compared based on subject characteristics. From 81 participants (51% male, median age 9 years), 89 samples were collected and the 16S rRNA genes of 77 (86.5%) samples were successfully analyzed. Subjects included 23 cystic fibrosis (CF), 19 immunocompromised (IC), and 28 non-immunocompromised (nIC) patients. Of 68 organisms identified in culture, 16S-based analyses were concordant with culture results in 66 (97.1%), and also identified potentially clinically significant taxa missed by cultures (e.g. Staphylococcus, Legionella, Pseudomonas). Significant differences in abundance were noted mostly for non-cultured taxa with diagnosis and antibiotic use (Veillonella, Corynebacterium, Haemophilus). The microbiota of CF samples was less diverse and a "core" group of fifteen taxa shared across samples was identified. 16S-based culture independent analysis was concordant with routine cultures and showed potential to detect non-cultured pathogens. While 16S- based testing identified relative changes in organism abundance associated with clinical characteristics, distinct microbiome profiles associated with disease states were not identified.

Environmental pediatrics: an emerging issue.

To review the most relevant articles regarding environmental pediatrics, its potential effects on health, and especially its advances in prevention. A literature search was conducted using MEDLINE/PubMed and SciELO databases. Articles from 1990 to 2010 were reviewed, in addition to book chapters related to environmental pediatrics. There is a significant variety of factors that make children highly vulnerable to environmental hazard exposure, which are mainly associated with children's comparatively greater consumption of water, food, and air in relation to body weight. According to the World Health Organization, every year more than 3 million children under the age of 5 die because of environment-related conditions. Approximately 30 to 40% of pediatric diseases are related to environmental factors. Children are constantly exposed to various environmental health hazards, among which the following stand out: contaminated water, lack of adequate sanitation facilities, air pollution, disease vectors, chemical hazards, injuries, and accidents. Nowadays, pediatricians are challenged to address environmental pediatrics health care needs. The pediatric health history needs to be more comprehensive by adding pointed questions to help identify potential environmental risks. Awareness and understanding of the noxious effects of various environmental conditions and knowledge of the related prevention measures will result in timely and adequate interventions that will improve our children's health and development.

Combat zone trauma poses a unique set of challenges and injury patterns not seen in the civilian setting. The role of the pediatric resuscitative thoracotomy in combat zones remains unclear given a paucity of data regarding procedure outcomes in this setting. We compare outcomes among children in traumatic arrest undergoing resuscitative thoracotomy versus cardiopulmonary (CPR) resuscitation only. We queried the Department of Defense Trauma Registry (DODTR) from 2007 to 2016 for all pediatric subjects that underwent a resuscitative thoracotomy or CPR in the prehospital or emergency department setting during operations in Iraq or Afghanistan. We removed CPR subjects with mechanisms of injury not matched in the thoracotomy cohort. During the study period, there were 3439 pediatric encounters. We identified 13 subjects who underwent a resuscitative thoracotomy and 66 subjects who underwent CPR without thoracotomy with matching mechanisms of injury. When comparing the two cohorts those in the thoracotomy group had higher median thorax body region scores (median 3 versus 0, p = .001), but a trend towards higher rates of survival to discharge (31% versus 9%, p = .108). The youngest survivor in the thoracotomy cohort was less than 1 year old. We observed a trend towards higher survival among subjects that underwent a resuscitative thoracotomy survived to hospital discharge compared to subjects undergoing CPR without thoracotomy. The literature will benefit from further data to confirm an association between this procedure and a survival benefit among pediatric subjects in the resource limited setting. Furthermore, improvements in documentation will guide equipping and training providers expected to care for pediatric trauma patients. Published by Elsevier Ltd.

Poor sleep is a major health concern, and there is evidence that young adults are at increased risk of suffering from poor sleep. There is also evidence that sleep duration can vary as a function of gender and body mass index (BMI). We sought to replicate these findings in a large sample of young adults, and also tested the hypothesis that a smaller gap between subjective sleep duration and subjective sleep need is associated with a greater feeling of being restored. A total of 2,929 university students (mean age 23.24±3.13 years, 69.1% female) took part in an Internet-based survey. They answered questions related to demographics and subjective sleep patterns. We found no gender differences in subjective sleep duration, subjective sleep need, BMI, age, or feeling of being restored. Nonlinear associations were observed between subjective sleep duration, BMI, and feeling of being restored. Moreover, a larger discrepancy between subjective actual sleep duration and subjective sleep need was associated with a lower feeling of being restored. The present pattern of results from a large sample of young adults suggests that males and females do not differ with respect to subjective sleep duration, BMI, or feeling of being restored. Moreover, nonlinear correlations seemed to provide a more accurate reflection of the relationship between subjective sleep and demographic variables.

The circadian rhythm in serum iron concentration was studied in 61 elderly men (74 +/- 6 years of age) and 93 women (78 +/- 8 years of age) in Bucharest, Romania, in 81 clinically healthy boys and 103 girls (11 +/- 1.5 years of age) in Tîrgovişte, Romania, in 4 elderly men and 19 women (71 +/- 5 years of age) and in 75 young-adult men (24 +/- 11 years of age) and 52 women (24 +/- 9 years of age) in St. Paul, Minnesota, USA. Six samples were obtained from each subject around a 24-hour span. The sampling sessions in the elderly subjects in Romania and in the children extended over all four seasons. A circadian rhythm statistically verified by Cosinor analysis was evident in all groups in both locations. A statistically significant sex difference with lower circadian mean (mesor) and a lower amplitude in the women was found in the Romanian elderly subjects. The children in Romania showed no sex difference in any circadian rhythm parameters. The young adult subjects in Minnesota showed a significantly higher mesor and a phase delay in the men as compared with the women. The elderly subjects of both sexes at both geographic locations had a lower circadian mesor than the young adults and the children. In the Romanian elderly subjects also the circadian amplitude was lower, which was not the case in the Minnesotans. While the acrophase in the elderly subjects and in the children in Romania was comparable (0928 and 0932 local time resp.), the young adults in Minnesota showed in comparison to the Romanians a phase delay (1132 local time) and the elderly in Minnesota showed a phase advance (0732 local time) in comparison to all other groups. The latter finding will have to be confirmed by more extensive studies. In the elderly subjects in Romania the circadian rhythm in serum iron concentration was in phase with the circadian rhythms in total serum bilirubin and alkaline phosphatase but showed significant phase differences from the circadian rhythms in serum albumin, urea

The experiences of young people who have siblings with life-limiting illnesses are not well understood. The study proposed to identify the concerns of siblings of pediatric palliative care (PPC) patients. Semistructured interviews were administered to participants and analyzed using qualitative inductive thematic analysis. Study subjects were 18 siblings of PPC patients aged 9 to 22 living in the Auckland area. The siblings of PPC patients held concerns about their siblings' impending death and desires to be involved in their lives and care. Siblings may benefit from opportunities to be involved in conversations about mortality and the care of their ill sibling. They are able to express their concerns and help provide care to PPC patients.

The aim of our study was to evaluate our liver transplant pediatric patients and to report our experience in the complications and the long-term follow-up results. Patients between the ages of 0 and 18 years, who had liver transplantation in the organ transplantation center of our university hospital between 1997 and 2016, were included in the study. The age, sex, indications for the liver transplantation, complications after the transplantation, and long-term follow-up findings were retrospectively evaluated. The obtained results were analyzed with statistical methods. In our organ transplantation center, 62 pediatric liver transplantations were carried out since 1997. The mean age of our patients was 7.3 years (6.5 months-17 years). The 4 most common reasons for liver transplantation were: Wilson's disease (n=10; 16.3%), biliary atresia (n=9; 14.5%), progressive familial intrahepatic cholestasis (n=8; 12.9%), and cryptogenic cirrhosis (n=7; 11.3%). The mortality rate after transplantation was 19.6% (12 of the total 62 patients). The observed acute and chronic rejection rates were 34% and 4.9%, respectively. Thrombosis (9.6%) was observed in the hepatic artery (4.8%) and portal vein (4.8%). Bile leakage and biliary stricture rates were 31% and 11%, respectively. 1-year and 5-year survival rates of our patients were 87% and 84%, respectively. The morbidity and mortality rates in our organ transplantation center, regarding pediatric liver transplantations, are consistent with the literature.

The return of genetic research results after death in the pediatric setting comes with unique complexities. Researchers must determine which results and through which processes results are returned. This paper discusses the experience over 15 years in pediatric cancer genetics research of returning research results after the death of a child and proposes a preventive ethics approach to protocol development in order to improve the quality of return of results in pediatric genomic settings. © 2015 American Society of Law, Medicine & Ethics, Inc.

Determining the optimal CT technique to minimize patient radiation exposure while maintaining diagnostic utility requires patient-specific protocols that are based on patient characteristics. This work develops relationships between different anthropometrics and CT image noise to determine appropriate protocol classification schemes. We measured the image noise in 387 CT examinations of pediatric patients (222 boys, 165 girls) of the chest, abdomen, and pelvis and generated mathematic relationships between image noise and patient lateral and anteroposterior dimensions, age, and weight. At the chest level, lateral distance (ld) across the body is strongly correlated with weight (ld = 0.23 × weight + 16.77; R(2) = 0.93) and is less well correlated with age (ld = 1.10 × age + 17.13; R(2) = 0.84). Similar trends were found for anteroposterior dimensions and at the abdomen level. Across all studies, when acquisition-specific parameters are factored out of the noise, the log of image noise was highly correlated with lateral distance (R(2) = 0.72) and weight (R(2) = 0.72) and was less correlated with age (R(2) = 0.62). Following first-order relationships of image noise and scanner technique, plots were formed to show techniques that could achieve matched noise across the pediatric population. Patient lateral distance and weight are essentially equally effective metrics to base maximum technique settings for pediatric patient-specific protocols. These metrics can also be used to help categorize appropriate reference levels for CT technique and size-specific dose estimates across the pediatric population.

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.

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.

The aim of this study was to investigate the effect of 8 wk of exercise training on functional capacity, muscular strength, body composition, and vascular function in sedentary but healthy subjects by using a randomized, crossover protocol. After familiarization sessions, 19 subjects aged 47 +/- 2 yr (mean +/- SE) undertook a randomized, crossover design study of the effect of 8 wk of supervised circuit training consisting of combined aerobic and resistance exercise. Peak oxygen uptake (.VO(2peak)), sum of 7 maximal voluntary contractions and the sum of 8 skinfolds and 5 segment girths were determined at entry, crossover, and 16 wk. Endothelium-dependent and -independent vascular function were determined by forearm strain-gauge plethysmography and intrabrachial infusions of acetylcholine (ACh) and sodium nitroprusside (SNP) in 16 subjects. Training did not alter ACh or SNP responses. .VO(2peak), (28.6 +/- 1.1 to 32.6 +/- 1.3 mL.kg(-1).min(-1), P < 0.001), exercise test duration (17.4 +/- 1.1 to 22.1 +/- 1.2 min, P < 0.001), and muscular strength (465 +/- 27 to 535 +/- 27 kg, P < 0.001) significantly increased after the exercise program, whereas skinfolds decreased (144 +/- 10 vs 134 +/- 9 mm, P < 0.001). These results suggest that moderate intensity circuit training designed to minimize the involvement of the arms improves functional capacity, body composition, and strength in healthy, middle-aged subjects without significantly influencing upper limb vascular function. This finding contrasts with previous studies in subjects with type 2 diabetes and heart failure that employed an identical training program.

Purpose of the Study: This research integrates successful aging and developmental adaptation models to empirically define the direct and indirect effects of 2 distal (i.e., education and past life experiences) and 5 proximal influences (i.e., physical functioning, cognitive functioning, physical health impairment, social resources, and perceived economic status) on subjective well-being. The proximal influences involved predictors outlined in most extant models of successful aging (e.g., Rowe & Kahn, 1998 [Rowe, J. W., & Kahn, R. L. (1998). Successful aging. New York: Pantheon Books.]). Our model extends such models by including distal impact as well as interactions between distal and proximal impacts. Design and Methods: Data were obtained from 234 centenarians and 72 octogenarians in the Georgia Centenarian Study. Structural equation modeling was conducted with Mplus 6.1. Results: Results showed significant direct effects of physical health impairment and social resources on positive aspects of subjective well-being among oldest-old adults. We also found significant indirect effects of cognitive functioning and education on positive affect among oldest-old adults. Social resources mediated the relationship between cognitive functioning and positive affect; and cognitive functioning and social resources mediated the relationship between education and positive affect. In addition, physical health impairment mediated the relationship between cognitive functioning and positive affect; and cognitive functioning and physical health impairment mediated the relationship between education and positive affect. Implications: Integrating 2 different models (i.e., successful aging and developmental adaptation) provided a comprehensive view of adaptation from a developmental perspective. PMID:25112594

In this study, we compared key temporal points in the whole body pointing movement of healthy aging and young subjects. During this movement, subject leans forward from a standing position to reach a target. As it involves forward inclination of the trunk, the movement creates a risk for falling. We examined two strategic time points during the task-first, the crossover point where the velocity of the center of mass (CoM) in the vertical dimension outstripped the velocity in the anteroposterior dimension and secondly, the time to peak of the CoM velocity profile. Transitions to stabilizing postures occur at these time points. They both occurred earlier in aging subjects. The crossover point also showed adjustments with target distance in aging subjects, while this was not observed in younger subjects. The shifts in these key time points could not be attributed to differences in movement duration between the two groups. Investigation with an optimal control model showed that the temporal adjustment as a function of target distance in the healthy aging subjects fits into a strategy that emphasized equilibrium maintenance rather than absolute work as a control strategy.

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.

Study Objectives: Respiratory and heart rate variability exhibit fractal scaling behavior on certain time scales. We studied the short-term and long-term correlation properties of heartbeat and breathing-interval data from disease-free subjects focusing on the age-dependent fractal organization. We also studied differences across sleep stages and night-time wake and investigated quasi-periodic variations associated with cardiac risk. Design: Full-night polysomnograms were recorded during 2 nights, including electrocardiogram and oronasal airflow. Setting: Data were collected in 7 laboratories in 5 European countries. Participants: 180 subjects without health complaints (85 males, 95 females) aged from 20 to 89 years. Interventions: None. Measurements and Results: Short-term correlations in heartbeat intervals measured by the detrended fluctuation analysis (DFA) exponent α1 show characteristic age dependence with a maximum around 50–60 years disregarding the dependence on sleep and wake states. Long-term correlations measured by α2 differ in NREM sleep when compared with REM sleep and wake, besides weak age dependence. Results for respiratory intervals are similar to those for α2 of heartbeat intervals. Deceleration capacity (DC) decreases with age; it is lower during REM and deep sleep (compared with light sleep and wake). Conclusion: The age dependence of α1 should be considered when using this value for diagnostic purposes in post-infarction patients. Pronounced long-term correlations (larger α2) for heartbeat and respiration during REM sleep and wake indicate an enhanced control of higher brain regions, which is absent during NREM sleep. Reduced DC possibly indicates an increased cardiovascular risk with aging and during REM and deep sleep. Citation: Schumann AY; Bartsch RP; Penzel T; Ivanov PC; Kantelhardt JW.

AIM To examine the extent to which the theory of planned behavior (TPB) predicts academic clinicians’ intent to treat pediatric obesity. METHODS A multi-disciplinary panel iteratively devised a Likert scale survey based on the constructs of the TPB applied to a set of pediatric obesity themes. A cross-sectional electronic survey was then administered to academic clinicians at tertiary care centers across Canada from January to April 2012. Descriptive statistics were used to summarize demographic and item agreement data. A hierarchical linear regression analysis controlling for demographic variables was conducted to examine the extent to which the TPB subscales predicted intent to treat pediatric obesity. RESULTS A total of 198 physicians, surgeons, and allied health professionals across Canada (British Columbia, Alberta, Manitoba, Saskatchewan, Nova Scotia, Ontario and Quebec) completed the survey. On step 1, demographic factors accounted for 7.4% of the variance in intent scores. Together in step 2, demographic variables and TPB subscales predicted 56.9% of the variance in a measure of the intent to treat pediatric obesity. Perceived behavioral control, that is, confidence in one’s ability to manage pediatric obesity, and subjective norms, congruent with one’s context of practice, were the most significant predictors of the intent to treat pediatric obesity. Attitudes and barriers did not predict the intent to treat pediatric obesity in this context. CONCLUSION Enhancing self-confidence in the ability to treat pediatric obesity and the existence of supportive treatment environments are important to increase clinician’s intent to treat pediatric obesity.

Although previous reports indicate that nocturnal plasma melatonin secretion declines with age, some recent findings do not support this point. In the present cross-sectional study, we documented serum melatonin concentrations at two time points, 02:00 and 08:00 h, in 144 persons aged 30-110 yr and found a significant age-related decline. It began around the age of 60 and reached a very significantly lower level in subjects in their 70s and over 80 yr of age (P < 0.01, when compared with age <60 yr). Nocturnal melatonin levels were higher among (post-menopausal only) women than men overall (P < 0.05). In the older age-groups, nocturnal melatonin levels did not differ between healthy controls and subjects with high blood pressure or ischemic heart disease. To further check these results, we also assessed the circadian pattern of serum melatonin in four subgroups of healthy men, aged 30-39, 40-49, 50-59, and 60-69 yr: blood samples were taken at 2 h intervals from 08:00 to 22:00 h and hourly from 22:00 to 08:00 h. Our results showed generally similar circadian melatonin patterns that peaked at night with very low levels during the daytime. No significant difference was found among the three younger groups, but nocturnal melatonin levels were significantly lower in the men in their 60s.

Comparison of Oral and Axillary Temperatures in Intubated Pediatric Patients.

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.

Eating habits may have a key influence on cognitive function, however, the relationship between dietary intake and cognitive impairment in the elderly Chinese population has not been explored. The present study investigated the association between cognitive impairment and eating habits in elderly Chinese subjects >90 years of age. This study comprised data from subjects included in the 2005 Project of Longevity and Ageing in Dujiangyan, China. Subjects were divided into two groups: cognitive impairment group and normal group. Sociodemographic and dietary habit data were collected and cognitive function was assessed in all subjects using the Mini-Mental State Examination. Data from 763 subjects (249 men, 514 women) were included. There was no statistically significant difference in eating habits between the two groups. Education level in the cognitive impairment group was significantly lower than in the normal group. Significant between-group differences were detected in factors relating to subjects' professions. Eating habits were not related to cognitive impairment in elderly Chinese people >90 years of age.

To characterize the availability of pediatric rheumatology training in general pediatric residencies. We surveyed 195 pediatric residency program directors in the US using a combined Web-based and paper-based survey format. The survey asked directors about the availability of an on-site pediatric rheumatologist in their institution, the availability of formal pediatric rheumatology rotations, and the types of physicians involved in teaching curriculum components related to pediatric rheumatology. Survey responses were analyzed using descriptive and bivariate statistics. Of the 195 program directors surveyed, 127 (65%) responded. More than 40% of responding programs did not have a pediatric rheumatologist on site. Programs with on-site pediatric rheumatologists were significantly more likely than those without on-site pediatric rheumatologists to have an on-site pediatric rheumatology rotation available (94% versus 9%; P < 0.001). Although pediatric rheumatologists' involvement in 4 curriculum areas relevant to pediatric rheumatology is nearly universal in programs with on-site pediatric rheumatologists, nearly two-thirds of programs without on-site pediatric rheumatologists rely on internist rheumatologists, general pediatricians, or other physicians to cover these areas. Programs without pediatric rheumatologists on site are less likely to have pediatric rheumatology rotations and are more likely to rely on internist rheumatologists and nonrheumatologists to address rheumatology-related curriculum components. Lack of exposure to pediatric rheumatology during residency may impede general pediatricians' ability to identify and treat children with rheumatic diseases, undermine resident interest in this field, and perpetuate low levels of supply.

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.

The safety of pharmacologic treatment for pediatric obesity.

Pediatric obesity is a serious public health concern. Five medications have been approved by the Food and Drug Administration (FDA) for chronic weight management in adults with obesity, when used as an adjunct to lifestyle modification. Orlistat is the only FDA-approved medication for pediatric patients aged 12 years and above. Areas covered: This paper summarizes safety and efficacy data from clinical trials of weight loss medications conducted among pediatric samples. Relevant studies were identified through searches in PubMed. Expert opinion: Orlistat, as an adjunct to lifestyle modification, results in modest weight losses and may be beneficial for some pediatric patients with obesity. However, gastrointestinal side effects are common and may limit use. In adults taking orlistat, rare but severe adverse events, including liver and renal events, have been reported. Recent pediatric pharmacokinetic studies of liraglutide have demonstrated similar safety and tolerability profiles as found in adults, with gastrointestinal disorders being the most common adverse events. Clinical trials are needed of liraglutide, as well as other medications for obesity, that systematically evaluate their risks and benefits in pediatric patients.

Experimental Injury Biomechanics of the Pediatric Neck

Motor vehicle related crashes rank as the most common cause of spinal related injuries in the pediatric population (Platzer et al. 2007; Brown et al. 2001; Kokoska et al. 2001; Eleraky et al. 2000; Hamilton and Myles 1992a; Bonadio 1993; Babcock 1975). Pediatric spinal related trauma accounts for between 1 and 12 % of all spinal related injuries (Hamilton and Myles 1992a; Hadley et al. 1988; Aufdermaur 1974). Cervical spine trauma in children accounts for approximately 2 % of all cervical spinal injuries (Henrys et al. 1977). Approximately 1-2 % of all children admitted for traumatic injury are related to injuries to the cervical spine (Platzer et al. 2007; Brown et al. 2001; Kokoska et al. 2001; Orenstein et al. 1994; Rachesky et al. 1987). Overall, pediatric neck injury rates are significantly lower than adult rates; however, the neck injury rate in children between the ages of 11 and 15 years approaches the adult rate of 18.8 per 100,000 (McGrory et al 1993; Myers and Winkelstein 1995). For children less than 11 years of age, neck injuries are relatively rare (1.2 per 100,000), but have particularly devastating consequences (McGrory et al. 1993). The overall mortality rate amongst victims of pediatric spinal trauma is approximately 16-41 % but considerably higher for the youngest ages (Platzer et al. 2007; Brown et al. 2001; Kokoska et al. 2001; Eleraky et al. 2000; Givens et al. 1996; Orenstein et al. 1994; Hamilton and Myles 1992b).

Vedolizumab is effective for inducing and maintaining remission in adults with inflammatory bowel disease (IBD); however, there is limited pediatric data. This study aimed to describe the adverse events and clinical response to vedolizumab in refractory pediatric IBD. Disease activity indices, clinical response, concomitant medication use, and adverse events were measured over 22 weeks in an observational prospective cohort study of children with refractory IBD who had failed anti-tumor necrosis factor therapy and subsequently initiated vedolizumab therapy. Twenty-one subjects, 16 with Crohn disease, received vedolizumab. Clinical response was observed in 6/19 (31.6%) of the evaluable subjects at week 6 and in 11/19 (57.9%) by week 22. Before induction, 15/21 (71.4%) participants were treated with systemic corticosteroids, as compared with 7/21 (33.3%) subjects at 22 weeks. Steroid-free remission was seen in 1/20 (5.0%) subjects at 6 weeks, 3/20 (15.0%) at 14 weeks, and 4/20 (20.0%) at 22 weeks. There was statistically significant improvement in serum albumin and hematocrit; however, C-reactive protein increased by week 22 (P < 0.05). There were no infusion reactions. Vedolizumab was discontinued in 2 patients because of severe colitis, requiring surgical intervention. There is limited experience with vedolizumab therapy in pediatric IBD. There seems to be a marked number of subjects with clinical response in the first 6 weeks that increases further by week 22 despite the severity of disease in this cohort. Adverse events may not be directly related to vedolizumab. This study is limited by small sample size, and larger prospective studies are warranted.

Techniques to quantify plasma HIV-1 RNA viral load (VL) are commercially available, and they are adequate for monitoring adults infected by HIV and treated with antiretroviral drugs. Little experience on HIV VL has been reported in pediatric cases. In Argentina, the evaluation of several assays for VL in pediatrics are now being considered. To evaluate the pediatric protocol for bDNA assay in HIV-infected children, 25 samples from HIV-infected children (according to CDC criteria for pediatric AIDS) were analyzed by using Quantiplex HIV RNA 2.0 Assay (Chiron Corporation) following the manufacturer's recommendations in a protocol that uses 50 microliters of patient's plasma (sensitivity: 10,000 copies/ml). When HIV-RNA was not detected, samples were run with the 1 ml standard bDNA protocol (sensitivity: 500 HIV-RNA c/ml). Nine samples belonged to infants under 12 months of age (group A) and 16 were over 12 months (group B). All infants under one year of age had high HIV-RNA copies in plasma. VL ranged from 30,800 to 2,560,000 RNA copies/ml (median = 362,000 c/ml) for group A and < 10,000 to 554,600 c/ml (median = < 10,000) for group B. Only 25% of children in group B had detectable HIV-RNA. By using the standard test of quantification, none of the patients had non detectable HIV-RNA, ranging between 950 and 226,200 c/ml for group B (median = 23,300 RNA c/ml). The suggested pediatric protocol could be useful in children under 12 months of age, but 1 ml standard protocol must be used for older children. Samples with undetectable results from children under one year of age should be repeated using the standard protocol.

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.

Hypertensive crisis in children is a relatively rare condition presenting with elevated blood pressure (BP) and related symptoms, and it is potentially life-threatening. The aim of this study was to survey children with first attacks of hypertensive crisis arriving at the emergency department (ED), and to determine the related parameters that predicted the severity of hypertensive crisis in children by age group. This was a retrospective study conducted from 2000 to 2007 in pediatric patients aged 18 years and younger with a diagnosis of hypertensive crisis at the ED. All patients were divided into four age groups (infants, preschool age, elementary school age, and adolescents), and two severity groups (hypertensive urgency and hypertensive emergency). BP levels, etiology, severity, and clinical manifestations were analyzed by age group and compared between the hypertensive emergency and hypertensive urgency groups. The mean systolic/diastolic BP in the hypertensive crisis patients was 161/102 mmHg. The major causes of hypertensive crisis were essential hypertension, renal disorders and endocrine/metabolic disorders. Half of all patients had a single underlying cause, and 8 had a combination of underlying causes. Headache was the most common symptom (54.5%), followed by dizziness (45.5%), nausea/vomiting (36.4%) and chest pain (29.1%). A family history of hypertension was a significant predictive factor for the older patients with hypertensive crisis. Clinical manifestations and severity showed a positive correlation with age. In contrast to diastolic BP, systolic BP showed a significant trend in the older children. Primary clinicians should pay attention to the pediatric patients who present with elevated blood pressure and related clinical hypertensive symptoms, especially headache, nausea/vomiting, and altered consciousness which may indicate that appropriate and immediate antihypertensive medications are necessary to prevent further damage.

How to perform Subjective Global Nutritional assessment in children.

PubMed

Secker, Donna J; Jeejeebhoy, Khursheed N

2012-03-01

Subjective Global Assessment (SGA) is a method for evaluating nutritional status based on a practitioner's clinical judgment rather than objective, quantitative measurements. Encompassing historical, symptomatic, and physical parameters, SGA aims to identify an individual's initial nutrition state and consider the interplay of factors influencing the progression or regression of nutrition abnormalities. SGA has been widely used for more than 25 years to assess the nutritional status of adults in both clinical and research settings. Perceiving multiple benefits of its use in children, we recently adapted and validated the SGA tool for use in a pediatric population, demonstrating its ability to identify the nutritional status of children undergoing surgery and their risk of developing nutrition-associated complications postoperatively. Objective measures of nutritional status, on the other hand, showed no association with outcomes. The purpose of this article is to describe in detail the methods used in conducting nutrition-focused physical examinations and the medical history components of a pediatric Subjective Global Nutritional Assessment tool. Guidelines are given for performing and interpreting physical examinations that look for evidence of loss of subcutaneous fat, muscle wasting, and/or edema in children of different ages. Age-related questionnaires are offered to guide history taking and the rating of growth, weight changes, dietary intake, gastrointestinal symptoms, functional capacity, and any metabolic stress. Finally, the associated rating form is provided, along with direction for how to consider all components of a physical exam and history in the context of each other, to assign an overall rating of normal/well nourished, moderate malnutrition, or severe malnutrition. With this information, interested health professionals will be able to perform Subjective Global Nutritional Assessment to determine a global rating of nutritional status for infants

The treatment of pediatric surgery diseases via utilization of aerosol delivery mechanisms is in progress for the betterment of pediatric care. Over the years, aerosol therapy has come to play an integral role in the treatment of pediatric respiratory diseases. Inhaled aerosol agents such as bronchodilators, corticosteroids, antibiotics, and mucolytics are commonly delivered to spontaneously breathing pediatric patients with a tracheostomy. Administering therapeutic inhaled aerosols to pediatric patients is challenging. The pediatric population ranges in age, which means patients with different airway sizes, breathing patterns, and cooperation levels. These patient-related factors impact the deposition of aerosol drugs in the lungs. The present review article will discuss the recent advancements in the delivery mechanisms for aerosol therapy in pediatric patients with respiratory diseases.

Purpose The primary purposes of this study were to examine the effects of hearing loss and respondent type (self- vs. parent-proxy report) on subjective fatigue in children. We also examined associations between child-specific factors and fatigue ratings. Method Subjective fatigue was assessed using the Pediatric Quality of Life Inventory Multidimensional Fatigue Scale (PedsQL-MFS; Varni, Burwinkle, Katz, Meeske, & Dickinson, 2002). We compared self- and parent-proxy ratings from 60 children with hearing loss (CHL) and 43 children with normal hearing (CNH). The children ranged in age from 6 to 12 years. Results School-age CHL experienced more overall and cognitive fatigue than CNH, although the differences were smaller than previously reported. Parent-proxy report was not strongly associated with child self-report, and parents tended to underestimate their child's fatigue, particularly sleep/rest fatigue. Language ability was also associated with subjective fatigue. For CHL and CNH, as language abilities increased, cognitive fatigue decreased. Conclusions School-age CHL experience more subjective fatigue than CNH. The poor association between parent-proxy and child reports suggests that the parent-proxy version of the PedsQL-MFS should not be used in isolation when assessing fatigue in school-age children. Future research should examine how language abilities may modulate fatigue and its potential academic consequences in CHL. PMID:29049623

In pediatric dentistry, the experiences of dental students may help dental educators better prepare graduates to treat the children. Research suggests that student's perceptions should be considered in any discussion of their education, but there has been no systematic examination of India's undergraduate dental students learning experiences. This qualitative investigation aimed to gather and analyze information about experiences in pediatric dentistry from the students' viewpoint using critical incident technique (CIT). The sample group for this investigation came from all 240 3rd and 4th year dental students from all the four dental colleges in Indore. Using CIT, participants were asked to describe at least one positive and one negative experience in detail. They described 308 positive and 359 negative experiences related to the pediatric dentistry clinic. Analysis of the data resulted in the identification of four key factors related to their experiences: 1) The instructor; 2) the patient; 3) the learning process; and 4) the learning environment. The CIT is a useful data collection and analysis technique that provides rich, useful data and has many potential uses in dental education.

As previous studies of obesity in survivors of pediatric acute lymphoblastic leukemia (ALL) have primarily been conducted among non-Hispanic white survivors or children treated on older protocols, our objective was to describe the prevalence and correlates of overweight status among an ethnically diverse population of pediatric ALL survivors, largely treated with more contemporary therapies. We evaluated the overweight/obesity status of pediatric ALL survivors (n=406) followed in the Texas Children's Cancer Center between 2004 and 2014. Survivors were classified as underweight, normal weight, overweight, or obese on the basis of their Body Mass Index (BMI) at their most current follow-up visit. Our results showed that Hispanic ethnicity (39% of subjects) was associated with being overweight (adjusted odds ratio [aOR]=1.88; 95% confidence interval [CI]: 1.13-3.14) or obese (aOR=2.84; 95% CI: 1.59-5.06) at follow-up, even after adjusting for cranial radiotherapy (CRT) exposure. BMI z-score at diagnosis was also associated with overweight/obesity at follow-up. Additionally, there was a statistically significant interaction between younger age at diagnosis and CRT, indicating that younger age at diagnosis was associated with obesity among patients who received CRT. These findings may help identify pediatric ALL patients that are at increased risk of being overweight or obese following treatment. PMID:26989911

With continued attention to pediatric sepsis at both the clinical and policy levels, it is important to understand the quality of hospitals in terms of their pediatric sepsis mortality. We sought to develop a method to evaluate hospital pediatric sepsis performance using 30-day risk-adjusted mortality and to assess hospital variation in risk-adjusted sepsis mortality in a large state-wide sample. Retrospective cohort study using administrative claims data. Acute care hospitals in the state of Pennsylvania from 2011 to 2013. Patients between the ages of 0-19 years admitted to a hospital with sepsis defined using validated International Classification of Diseases, Ninth revision, Clinical Modification, diagnosis and procedure codes. None. During the study period, there were 9,013 pediatric sepsis encounters in 153 hospitals. After excluding repeat visits and hospitals with annual patient volumes too small to reliably assess hospital performance, there were 6,468 unique encounters in 24 hospitals. The overall unadjusted mortality rate was 6.5% (range across all hospitals: 1.5-11.9%). The median number of pediatric sepsis cases per hospital was 67 (range across all hospitals: 30-1,858). A hierarchical logistic regression model for 30-day risk-adjusted mortality controlling for patient age, gender, emergency department admission, infection source, presence of organ dysfunction at admission, and presence of chronic complex conditions showed good discrimination (C-statistic = 0.80) and calibration (slope and intercept of calibration plot: 0.95 and -0.01, respectively). The hospital-specific risk-adjusted mortality rates calculated from this model varied minimally, ranging from 6.0% to 7.4%. Although a risk-adjustment model for 30-day pediatric sepsis mortality had good performance characteristics, the use of risk-adjusted mortality rates as a hospital quality measure in pediatric sepsis is not useful due to the low volume of cases at most hospitals.

Bispectral (BIS) analysis uses electroencephalogram information from a forehead electrode to calculate an index score (0 to 100; 0 = coma; 90 to 100 = awake). This index score correlates with the level of alertness in anesthetized patients. Classically, sedation has been monitored with clinical sedation scales such as the Observers Assessment of Alertness Sedation Scale (OAA/S), Modified Ramsey Scale, or a Visual Analog Scale (VAS). Our objective was to determine the correlation between clinical sedation scales and BIS index in pediatric patients undergoing sedation in an outpatient oral surgery setting. Prospective cohort study of patients aged 2 to 17 years undergoing sedation in an outpatient oral surgery office. Sedation was performed in the customary manner with the addition of BIS monitoring. Three clinical sedation scores (OAA/S: 5 to 1; 5 = awake, 1 = unresponsive; Modified Ramsey: 1 to 6; 1-2 = awake, 6 = unresponsive; VAS: 0 to 10; 0 = awake, 10 = unresponsive) were assigned every 5 minutes by an investigator blinded to the BIS index. Data were analyzed using a repeated measures linear regression model. Sixteen subjects undergoing oral surgery, ages 4.5 years to 17 years, were enrolled, mean age 12.6 years +/- 4.3 years (standard deviation). Patients received methohexital in addition to 1 or more of the following: nitrous oxide, fentanyl, or midazolam. The results of the longitudinal regression analysis showed a highly significant association between the sedation scales and the BIS index. The BIS monitor may be a useful adjunct in monitoring pediatric patients receiving sedation in the outpatient setting.

The lung just like all other organs is affected by age. The lung matures by the age of 20 and age-related changes start around middle age, at 40-50 years. Exhaled nitric oxide (F E NO) has been shown to be age, height and gender dependent. We hypothesize that the nitric oxide (NO) parameters alveolar NO (C A NO), airway flux (J aw NO), airway diffusing capacity (D aw NO) and airway wall content (C aw NO) will also demonstrate this dependence. Data from healthy subjects were gathered by the current authors from their earlier publications in which healthy individuals were included as control subjects. Healthy subjects (n = 433) ranged in age from 7 to 78 years. Age-stratified reference values of the NO parameters were significantly different. Gender differences were only observed in the 20-49 age group. The results from the multiple regression models in subjects older than 20 years revealed that age, height and gender interaction together explained 6% of variation in F E NO at 50 ml s -1 (F E NO 50 ), 4% in J aw NO, 16% in C aw NO, 8% in D aw NO and 12% in C A NO. In conclusion, in this study we have generated reference values for NO parameters from an extended NO analysis of healthy subjects. This is important in order to be able to use these parameters in clinical practice.

To determine whether obstructive sleep apnea (OSA) and/or nocturnal hypoxemia are associated with the severity of liver injury in patients with pediatric nonalcoholic fatty liver disease (NAFLD). Obese children aged 10-18 years with liver biopsy-proven NAFLD were enrolled. Demographic, clinical, and laboratory data were collected, polysomnography was performed, and liver histology was scored. Subjects were divided into those with OSA/hypoxemia and those without OSA/hypoxemia for analysis. Of 25 subjects with NAFLD, OSA/hypoxemia was present in 15 (60%) (mean age, 12.8 ± 1.9 years; 68% male; 88% Hispanic; mean body mass index z-score, 2.3 ± 0.3). Subjects with and without OSA/hypoxemia had similar levels of serum aminotransferases, serum lipids, and inflammatory and insulin resistance markers. Although there were no differences between groups in the histological severity of steatosis, inflammation, ballooning degeneration, NAFLD activity score, or histological grade, subjects with OSA/hypoxemia had significantly more severe hepatic fibrosis. Moreover, oxygen saturation nadir during polysomnography was related to hepatic fibrosis stage (r = -0.49; P = .01) and aspartate aminotransferase level (r = 0.42; P < .05). Increasing percentage of time with oxygen saturation ≤90% was related to NAFLD inflammation grade (r = 0.44; P = .03), degree of hepatic steatosis (r = -0.50; P = .01), NAFLD activity score (r = 0.42; P = .04), aspartate aminotransferase level (r = 0.56; P = .004), and alanine aminotransferase level (r = 0.44; P = .03). Moderate OSA/hypoxemia is common in pediatric patients with biopsy-proven NAFLD. OSA and the severity/duration of hypoxemia are associated with biochemical and histological measures of NAFLD severity. Copyright © 2014 Mosby, Inc. All rights reserved.

Designing a Pediatric Severe Sepsis Screening Tool

2014-01-01

We sought to create a screening tool with improved predictive value for pediatric severe sepsis (SS) and septic shock that can be incorporated into the electronic medical record and actively screen all patients arriving at a pediatric emergency department (ED). “Gold standard” SS cases were identified using a combination of coded discharge diagnosis and physician chart review from 7,402 children who visited a pediatric ED over 2 months. The tool’s identification of SS was initially based on International Consensus Conference on Pediatric Sepsis (ICCPS) parameters that were refined by an iterative, virtual process that allowed us to propose successive changes in sepsis detection parameters in order to optimize the tool’s predictive value based on receiver operating characteristics (ROC). Age-specific normal and abnormal values for heart rate (HR) and respiratory rate (RR) were empirically derived from 143,603 children seen in a second pediatric ED over 3 years. Univariate analyses were performed for each measure in the tool to assess its association with SS and to characterize it as an “early” or “late” indicator of SS. A split-sample was used to validate the final, optimized tool. The final tool incorporated age-specific thresholds for abnormal HR and RR and employed a linear temperature correction for each category. The final tool’s positive predictive value was 48.7%, a significant, nearly threefold improvement over the original ICCPS tool. False positive systemic inflammatory response syndrome identifications were nearly sixfold lower. PMID:24982852

Pediatricians generally need to treat adult patients who require long-term care for pediatric diseases. However, little is known about the characteristics of adult patients in pediatric wards. Using a national inpatient database, the aim of this study was to determine the clinical details of adult patients admitted to pediatric wards in Japanese acute-care hospitals. We extracted all inpatients aged ≥19 years who were admitted to pediatric departments in Japan from April 2012 to March 2013. We examined the patients' main diagnoses and the use of life-supporting home medical devices. Of 417,352 patients admitted to pediatric wards during the study period, we identified 4,729 (1.1%) adult patients. The major diagnoses of the adult patients were malignancy, congenital heart disease, epilepsy, and cerebral palsy. More than 35% of the patients with cerebral palsy had a tracheostomy tube, gastrostomy tube, home central venous alimentation, or home respirator. More than 20% of patients aged ≥40 years in pediatric wards had adult diseases, including ischemic heart diseases, cerebrovascular diseases, and adult malignancy. Many adult patients in pediatric wards had adult diseases. It is essential to establish a disease-oriented support system for adults with chronic conditions that originated in their childhood.

Social pediatrics teaches pediatric residents how to understand disease within their patients' social, environmental and political contexts. It's an essential component of pediatric residency training; however there is very little literature that addresses how such a broad-ranging topic can be taught effectively. The aim of this study was to determine and characterize social pediatric education in our pediatric residency training in order to identify strengths and gaps. A social pediatrics curriculum map was developed, attending to 3 different dimensions: (1) the intended curriculum as prescribed by the Objectives of Training for Pediatrics of the Royal College of Physicians and Surgeons of Canada (RCPSC), (2) the formal curriculum defined by rotation-specific learning objectives, and (3) the informal/hidden curriculum as reflected in resident and teacher experiences and perceptions. Forty-one social pediatric learning objectives were extracted from the RCPSC Objectives of Training for Pediatrics, most were listed in the Medical Expert (51%) and Health Advocate competencies (24%). Almost all RCPSC social pediatric learning objectives were identified in more than one rotation and/or seminar. Adolescent Medicine (29.2%), Pediatric Ambulatory Medicine (26.2%) and Developmental Pediatrics (25%) listed the highest proportion of social pediatric learning objectives. Four (10%) RCPSC social pediatric objectives were not explicitly named within learning objectives of the formal curriculum. The informal curriculum revealed that both teachers and residents viewed social pediatrics as integral to all clinical encounters. Perceived barriers to teaching and learning of social pediatrics included time constraints, particularly in a tertiary care environment, and the value of social pediatrics relative to medical expert knowledge. Despite the lack of an explicit thematic presentation of social pediatric learning objectives by the Royal College and residency training program

Pediatric heart transplantation at adult-specialty centers in the US: a multicenter registry analysis.

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 objective of the present study was to assess the concordance between parent and child report regarding different domains of pediatric health, headache in particular. In addition, the influence of potential moderator variables on the agreement between parents and children was examined. In an epidemiologic study on a randomly drawn sample of households with at least 1 child in the family between 7 and 14 years of age (community registries), various pediatric health disturbances (headache, other pains, somatic symptoms, and depression/anxiety) were assessed via both child (from the age of 9 y on) and parent report (n=3461). A relatively high parent-child agreement (sigmaM=0.61) was found regarding the variable headache frequency, whereas consensus regarding other pains was, for the most part, markedly lower. The lowest agreement (sigmaM=0.27) was found for depression/anxiety symptoms. A moderator analysis (with age, sex, and parental headache) between child and parent failed to reveal significant differences regarding the degree of agreement between the 2 data sources. Children reported more frequent and more severe symptoms in all health domains. The examined potential moderator variables did not elucidate processes underlying the differences in child and parent agreement. There is no convincing evidence that the children's appraisal is less valid than their parents'. In summary, parents' reports cannot be viewed as a substitute for children's reports in pediatric pain and health assessment. Instead, each perspective represents a unique subjective reality and as such, both are of importance for research on pediatric pain and other health variables.

To evaluate the correlation of a Pediatric Early Warning Score with unplanned transfer to the PICU in hospitalized oncology and hematopoietic stem cell transplant patients. We performed a retrospective matched case-control study, comparing the highest documented Pediatric Early Warning Score within 24 hours prior to unplanned PICU transfers in hospitalized pediatric oncology and hematopoietic stem cell transplant patients between September 2011 and December 2013. Controls were patients who remained on the inpatient unit and were matched 2:1 using age, condition (oncology vs hematopoietic stem cell transplant), and length of hospital stay. Pediatric Early Warning Scores were documented by nursing staff at least every 4 hours as part of routine care. Need for transfer was determined by a PICU physician called to evaluate the patient. A large tertiary/quaternary free-standing academic children's hospital. One hundred ten hospitalized pediatric oncology patients (42 oncology, 68 hematopoietic stem cell transplant) requiring unplanned PICU transfer and 220 matched controls. None. Using the highest score in the 24 hours prior to transfer for cases and a matched time period for controls, the Pediatric Early Warning Score was highly correlated with the need for PICU transfer overall (area under the receiver operating characteristic = 0.96), and in the oncology and hematopoietic stem cell transplant groups individually (area under the receiver operating characteristic = 0.95 and 0.96, respectively). The difference in Pediatric Early Warning Score results between the cases and controls was noted as early as 24 hours prior to PICU admission. Seventeen patients died (15.4%). Patients with higher Pediatric Early Warning Scores prior to transfer had increased PICU mortality (p = 0.028) and length of stay (p = 0.004). We demonstrate that our institution's Pediatric Early Warning Score is highly correlated with the need for unplanned PICU transfer in hospitalized oncology and

Presentation of suspected pediatric uveitis: Pediatric uveitis is usually managed in specialized ophthalmic centers in the UK. Meaningful data acquisition in these clinics may be helpful in clinical governance, and healthcare planning in a specialty that is gradually changing due to changes in treatment choices. Retrospective analysis of prospectively acquired data in the Liverpool pediatric uveitis database was performed. Analysis of our data, based on 147 patients, with a mean age of 10 years, indicated a female to male ratio of 2:1. 99% of patients were Caucasian. Our data indicates 86% of all patients attending the uveitis clinic were diagnosed with juvenile idiopathic arthritis, followed by intermediate uveitis 5% and idiopathic uveitis 4%. 46% of patients required treatment. Systemic treatment included methotrexate (34%), prednisolone (14%), etanercept (6%), ciclosporin (6%), mycophenolate (3%), and infliximab (1%). Severe visual loss (defined by counting fingers or below vision) was seen in 10 eyes despite appropriately treated chronic uveitis. Our data shows uveitis-related ocular morbidity in a predominantly pediatric Caucasian population. Patients with severe and chronic uveitis may experience significant uveitis-related complications and subsequent visual loss despite aggressive treatment.

To establish the incidence, mortality rate, and fracture location of pediatric patients injured while using an all-terrain vehicle (ATV) over an 11-year period. A retrospective study using a state trauma database for patients ages 0 to 17 years who sustained injuries while using an ATV. Thirty-two pediatric and adult trauma centers within the state were evaluated from January 1, 2004, to December 31, 2014. The inclusion criteria were met by 1912 patients. The estimated mean annual incidence during the period of the study was 6.2 patients per 100 000 children in the pediatric population <18 years of age. There was a decrease of 13.4% in the mean incidence when comparing the first 5 years of the study with the last 6 years. The median age of patients was 14 years. The median hospital length of stay and injury severity score were 3 days and 9, respectively. There were 28 fatalities (1.5%). The mean mortality incidence was 0.09 deaths per 100 000 children and remained relatively constant. The majority of patients (55.4%) sustained at least 1 bone fracture at or below the cervical spine. The femur and tibia were more commonly fractured (21.6% and 17.7% of the patients, respectively). Despite current guidelines by the American Academy of Pediatrics, patients younger than 16 years of age remain victims of ATV injuries. Although there was a 13.4% reduction in the incidence of ATV-related injuries in recent years, continued preventive guidelines are still necessary to avert these injuries in children and adolescents.

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

8-year retrospective analysis of intravenous arginine therapy for acute metabolic strokes in pediatric mitochondrial disease.

Intravenous (IV) arginine has been reported to ameliorate acute metabolic stroke symptoms in adult patients with Mitochondrial Encephalopathy with Lactic Acidosis and Stroke-like Episodes (MELAS) syndrome, where its therapeutic benefit is postulated to result from arginine acting as a nitric oxide donor to reverse vasospasm. Further, reduced plasma arginine may occur in mitochondrial disease since the biosynthesis of arginine's precursor, citrulline, requires ATP. Metabolic strokes occur across a wide array of primary mitochondrial diseases having diverse molecular etiologies that are likely to share similar pathophysiologic mechanisms. Therefore, IV arginine has been increasingly used for the acute clinical treatment of metabolic stroke across a broad mitochondrial disease population. We performed retrospective analysis of a large cohort of subjects who were under 18 years of age at IRB #08-6177 study enrollment and had molecularly-confirmed primary mitochondrial disease (n = 71, excluding the common MELAS m.3243A>G mutation). 9 unrelated subjects in this cohort received acute arginine IV treatment for one or more stroke-like episodes (n = 17 total episodes) between 2009 and 2016 at the Children's Hospital of Philadelphia. Retrospectively reviewed data included subject genotype, clinical symptoms, age, arginine dosing, neuroimaging (if performed), prophylactic therapies, and adverse events. Genetic etiologies of subjects who presented with acute metabolic strokes included 4 mitochondrial DNA (mtDNA) pathogenic point mutations, 1 mtDNA deletion, and 4 nuclear gene disorders. Subject age ranged from 19 months to 23 years at the time of any metabolic stroke episode (median, 8 years). 3 subjects had recurrent stroke episodes. 70% of subjects were on prophylactic arginine or citrulline therapy at the time of a stroke-like episode. IV arginine was initiated on initial presentation in 65% of cases. IV arginine was given for 1-7 days (median, 1 day). A

Objective: The aim of our study was to evaluate our liver transplant pediatric patients and to report our experience in the complications and the long-term follow-up results. Materials and Methods: Patients between the ages of 0 and 18 years, who had liver transplantation in the organ transplantation center of our university hospital between 1997 and 2016, were included in the study. The age, sex, indications for the liver transplantation, complications after the transplantation, and long-term follow-up findings were retrospectively evaluated. The obtained results were analyzed with statistical methods. Results: In our organ transplantation center, 62 pediatric liver transplantations were carried out since 1997. The mean age of our patients was 7.3 years (6.5 months–17 years). The 4 most common reasons for liver transplantation were: Wilson’s disease (n=10; 16.3%), biliary atresia (n=9; 14.5%), progressive familial intrahepatic cholestasis (n=8; 12.9%), and cryptogenic cirrhosis (n=7; 11.3%). The mortality rate after transplantation was 19.6% (12 of the total 62 patients). The observed acute and chronic rejection rates were 34% and 4.9%, respectively. Thrombosis (9.6%) was observed in the hepatic artery (4.8%) and portal vein (4.8%). Bile leakage and biliary stricture rates were 31% and 11%, respectively. 1-year and 5-year survival rates of our patients were 87% and 84%, respectively. Conclusion: The morbidity and mortality rates in our organ transplantation center, regarding pediatric liver transplantations, are consistent with the literature. PMID:28149148

Pressure ulcer (PU) is a localized trauma to the skin and or tissue beneath which lies in bony prominence due to pressure or pressure that combines with a sharp surface. Several studies have found that PU is a common problem in pediatrics population. Infection at the site of a PU is the most common complication in which the PU may host a resistant microorganism and may turn into a local infection that will be the source of bacteremia in hospitalized patients. To reveal which is the most common microbial species that underlie in pressure ulcer of pediatrics patients.A cross-sectional study was conducted in July-September 2017, involving 18 PU pediatric patients in Haji Adam Malik Hospital. To each subject, swab culture from the ulcer was madein microbial laboratory in Haji Adam Malik Hospital to determine the microbial pattern. This study found that the most common microbial pattern in pressure ulcers of pediatrics patient in Haji Adam Malik Hospital is Acinetobacter baumannii (22.2%).

Inaccuracy of age assessment from images of postpubescent subjects in cases of alleged child pornography.

PubMed

2013-03-01

Despite frequent medical expert testimony authoritatively stating that images of individuals who are postpubescent indicate age less than 18 and therefore, child pornography, developmental experts have noted that a scientific basis for such estimation is lacking. In fact, recent studies have demonstrated a high degree of inaccuracy in such estimates, and that the stage of breast development often used as indicative of age under 18 years is present in a substantial percentage of adult women. Ten images of adult women from legitimate pornographic sites promoting youthful images were shown to 16 pediatric endocrinologists expert in evaluating maturation, who determined whether or not the individuals represented were under 18 years of age. They also provided information about what features were most important in their evaluations. Sixty-nine percent of the 160 estimates were that the images represented females under 18 years of age. There was wide variability in the designation of importance of the various features of maturation in reaching conclusions, with breast development and facial appearance considered most important. This study confirms that medical testimony, even by experts in adolescent development, can deem images of adult women selected for their youthful appearance to be under age 18 two thirds of the time. Thus, important as prosecuting users of child pornographic material may be, justice requires the avoidance of testimony that is not scientifically based.

Emotional Intelligence Mediates the Relationship between Age and Subjective Well-Being

Individuals’ Subjective Well-being (SWB) increases as they grow older. Past literature suggests that emotional intelligence may increase with age and lead to higher levels of SWB in older adults. The primary purpose of the present study was to test whether emotional intelligence would mediate the relationship between age and SWB. A total of 360 Chinese adults (age range: 20 to 79 years old) participated in this study. They filled out questionnaires that assessed their age, life satisfaction (The Satisfaction with Life Scale), affective well-being (The Positive and Negative Affect Schedule), and emotional intelligence (The Wong and Law Emotional Intelligence Scale). Using Structural Equation Modeling, the mediation model was supported, χ2 (75) =194.21, p < .01; RMSEA =.07; CFI = .91. Emotional intelligence partially mediated the relationship between age and life satisfaction, and fully mediated the relationship between age and affective well-being. The findings suggest that older adults may use their increased emotional intelligence to enhance their SWB. PMID:27199490

Handgrip strength (HGS) is a useful indicator of nutrition status in adults, but evidence is lacking in pediatric patients. The aim of this study was to describe the association between undernutrition and HGS in pediatric patients at hospital admission, quantifying the modifying effect of disease severity, anthropometrics, and other patient characteristics on HGS. Eighty-nine inpatients aged ≥6 years consecutively admitted were recruited in a longitudinal study. Nutrition status was evaluated using body mass index (BMI) z scores, and HGS was evaluated at admission and discharge. In the total sample, 30.3% of patients were undernourished at admission, and 64% lost HGS during the hospital stay. This study showed that HGS at admission was independently associated with undernutrition defined by BMI z scores (β = 0.256, P = .037). In this multivariate analysis, sex, age, height, and BMI z scores explained 67.1% of HGS at hospital admission. Lower HGS may be a potential marker of undernutrition in hospitalized pediatric patients, although HGS data should be interpreted according to sex, age, and height of the patient.

The objective of this study was to evaluate the relationship between caffeine use, other drug use, and psychopathology in adolescents, using self-report measures. The study group consisted of 132 adolescents (average age 14.01 ± 2.06 years, 52% female, 19% African American, 5% other categories, 76% Caucasian). Most (47%) were recruited from a child psychiatry clinic with emphasis on youth with disruptive disorders, with 35% from an adolescent pediatric clinic with emphasis on prevention of risk-taking behavior and 18% from a pediatric clinic for families with limited resources. Subjects were consecutively recruited before or after regular clinic visits. Consent was obtained from parents and assent from the youth. High caffeine consumption was associated with daily cigarette use; aggressive behavior; conduct, attention deficit/hyperactivity, and social problems; and increased somatic complaints in adolescents.

Systematic reviews are key tools to enable decision making by healthcare providers and policymakers. Despite the availability of the evidence based Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA-2009 and PRISMA-P 2015) statements that were developed to improve the transparency and quality of reporting of systematic reviews, uncertainty on how to deal with pediatric-specific methodological challenges of systematic reviews impairs decision-making in child health. In this paper, we identify methodological challenges specific to the design, conduct and reporting of pediatric systematic reviews, and propose a process to address these challenges. One fundamental decision at the outset of a systematic review is whether to focus on a pediatric population only, or to include both adult and pediatric populations. Both from the policy and patient care point of view, the appropriateness of interventions and comparators administered to pre-defined pediatric age subgroup is critical. Decisions need to be based on the biological plausibility of differences in treatment effects across the developmental trajectory in children. Synthesis of evidence from different trials is often impaired by the use of outcomes and measurement instruments that differ between trials and are neither relevant nor validated in the pediatric population. Other issues specific to pediatric systematic reviews include lack of pediatric-sensitive search strategies and inconsistent choices of pediatric age subgroups in meta-analyses. In addition to these methodological issues generic to all pediatric systematic reviews, special considerations are required for reviews of health care interventions' safety and efficacy in neonatology, global health, comparative effectiveness interventions and individual participant data meta-analyses. To date, there is no standard approach available to overcome this problem. We propose to develop a consensus-based checklist of essential items which

Estimated radiation dose is important for assessing and communicating the risks and benefits of pediatric nuclear medicine studies. Radiation dose depends on the radiopharmaceutical, the administered activity, and patient factors such as age and size. Most radiation dose estimates for pediatric nuclear medicine have not been based on administered activities of radiopharmaceuticals recommended by established practice guidelines. The dosage card of the European Association of Nuclear Medicine (EANM) and the North American consensus guidelines each provide recommendations of administered activities of radiopharmaceuticals in children, but there are substantial differences between these two guidelines. For 12 commonly performed pediatric nuclear medicine studies, two established pediatric radiopharmaceutical administration guidelines were used to calculate updated radiation dose estimates and to compare the radiation exposure resulting from the recommendations of each of the guidelines. Estimated radiation doses were calculated for 12 common procedures in pediatric nuclear medicine using administered activities recommended by the dosage card of the EANM (version 1.5.2008) and the 2010 North American consensus guidelines for radiopharmaceutical administered activities in pediatrics. Based on standard models and nominal age-based weights, radiation dose was estimated for typical patients at ages 1, 5, 10 and 15 years and adult. The resulting effective doses were compared, with differences greater than 20% considered significant. Following either the EANM dosage card or the 2010 North American guidelines, the highest effective doses occur with radiopharmaceuticals labeled with fluorine-18 and iodine-123. In 24% of cases, following the North American consensus guidelines would result in a substantially higher radiation dose. The guidelines of the EANM dosage card would lead to a substantially higher radiation dose in 39% of all cases, and in 62% of cases in which patients

Evidence-based reference intervals (RIs) are essential to accurately interpret pediatric laboratory test results. To fill gaps in pediatric RIs, the Canadian Laboratory Initiative on Pediatric Reference Intervals (CALIPER) project developed an age- and sex-specific pediatric RI database based on healthy pediatric subjects. Originally established for Abbott ARCHITECT assays, CALIPER RIs were transferred to assays on Beckman, Roche, Siemens, and Ortho analytical platforms. This study provides transferred reference intervals for 29 biochemical assays for the Ortho VITROS 5600 Chemistry System (Ortho). Based on Clinical Laboratory Standards Institute (CLSI) guidelines, a method comparison analysis was performed by measuring approximately 200 patient serum samples using Abbott and Ortho assays. The equation of the line of best fit was calculated and the appropriateness of the linear model was assessed. This equation was used to transfer RIs from Abbott to Ortho assays. Transferred RIs were verified using 84 healthy pediatric serum samples from the CALIPER cohort. RIs for most chemistry analytes successfully transferred from Abbott to Ortho assays. Calcium and CO 2 did not meet statistical criteria for transference (r 2 <0.70). Of the 32 transferred reference intervals, 29 successfully verified with approximately 90% of results from reference samples falling within transferred confidence limits. Transferred RIs for total bilirubin, magnesium, and LDH did not meet verification criteria and are not reported. This study broadens the utility of the CALIPER pediatric RI database to laboratories using Ortho VITROS 5600 biochemical assays. Clinical laboratories should verify CALIPER reference intervals for their specific analytical platform and local population as recommended by CLSI.

Pediatric HIV patients often suffer with neurodevelopmental delay and subsequently cognitive impairment. While tissue injury in cortical and subcortical regions in the brain of adult HIV patients has been well reported there is sparse knowledge about these changes in perinatally HIV infected pediatric patients. We analyzed cortical thickness, subcortical volume, structural connectivity, and neurocognitive functions in pediatric HIV patients and compared with those of pediatric healthy controls. With informed consent, 34 perinatally infected pediatric HIV patients and 32 age and gender matched pediatric healthy controls underwent neurocognitive assessment and brain magnetic resonance imaging (MRI) on a 3 T clinical scanner. Altered cortical thickness, subcortical volumes, and abnormal neuropsychological test scores were observed in pediatric HIV patients. The structural network connectivity analysis depicted lower connection strengths, lower clustering coefficients, and higher path length in pediatric HIV patients than healthy controls. The network betweenness and network hubs in cortico-limbic regions were distorted in pediatric HIV patients. The findings suggest that altered cortical and subcortical structures and regional brain connectivity in pediatric HIV patients may contribute to deficits in their neurocognitive functions. Further, longitudinal studies are required for better understanding of the effect of HIV pathogenesis on brain structural changes throughout the brain development process under standard ART treatment.

Structural brain imaging studies in obsessive-compulsive disorder (OCD) have produced inconsistent findings. This may be partially due to limited statistical power from relatively small samples and clinical heterogeneity related to variation in illness profile and developmental stage. To address these limitations, the authors conducted meta- and mega-analyses of data from OCD sites worldwide. T 1 images from 1,830 OCD patients and 1,759 control subjects were analyzed, using coordinated and standardized processing, to identify subcortical brain volumes that differ between OCD patients and healthy subjects. The authors performed a meta-analysis on the mean of the left and right hemisphere measures of each subcortical structure, and they performed a mega-analysis by pooling these volumetric measurements from each site. The authors additionally examined potential modulating effects of clinical characteristics on morphological differences in OCD patients. The meta-analysis indicated that adult patients had significantly smaller hippocampal volumes (Cohen's d=-0.13; % difference=-2.80) and larger pallidum volumes (d=0.16; % difference=3.16) compared with adult controls. Both effects were stronger in medicated patients compared with controls (d=-0.29, % difference=-4.18, and d=0.29, % difference=4.38, respectively). Unmedicated pediatric patients had significantly larger thalamic volumes (d=0.38, % difference=3.08) compared with pediatric controls. None of these findings were mediated by sample characteristics, such as mean age or scanning field strength. The mega-analysis yielded similar results. The results indicate different patterns of subcortical abnormalities in pediatric and adult OCD patients. The pallidum and hippocampus seem to be of importance in adult OCD, whereas the thalamus seems to be key in pediatric OCD. These findings highlight the potential importance of neurodevelopmental alterations in OCD and suggest that further research on neuroplasticity in OCD

Attitudes about aging influence how people feel about their aging and affect psychological and health outcomes in later life. Given cross-cultural variability in such attitudes, the subjective experience of aging (e.g., subjective age [SA]) may also vary, potentially accounting for culture-specific patterns of aging-related outcomes. Our study explored cultural variation in SA and its determinants. American (N = 569), Chinese (N = 492), and German (N = 827) adults aged 30-95 years completed a questionnaire that included instruments measuring basic demographic information, SA, beliefs about thresholds of old age, control over life changes, and age dependency of changes in eight different life domains (i.e., family, work). Analyses revealed consistency across cultures in the domain-specificity of SA, but differences in the amount of shared variance across domains (e.g., Chinese adults exhibited greater homogeneity across domains than did Americans and Germans). Cultural differences were also observed in levels of SA in some domains, which were attenuated by domain-specific beliefs (e.g., control). Interestingly, beliefs about aging accounted for more cultural variation in SA than did sociodemographic factors (e.g., education). Our results demonstrate that subjective perceptions of aging and everyday functioning may be best understood from a perspective focused on context (i.e., culture, life domain). Given its important relation to functioning, examination of cross-cultural differences in the subjective experience of aging may highlight factors that determine variations in aging-related outcomes that then could serve as targets of culture-specific interventions promoting well-being in later life. © The Author 2017.

This article extends the conceptual knowledge of average relative subjective age in organizations by exploring organizational-level antecedents and consequences of employees, on average, feeling younger than their chronological age. We draw from the theories of selection-optimization-compensation and socioemotional selectivity to build a theoretical framework for relative subjective age in organizations. We hypothesize that companies in which employees, on average, perceive themselves to be younger than they actually are have a higher average individual goal accomplishment and, in turn, experience higher company performance. We further hypothesize that employees' average experience of high work-related meaning relates to a lower subjective age in organizations. In addition, we assess the role of environmental dynamism and age-inclusive human resource management as moderators in this theoretical model. Through empirically testing this model in a multisource dataset, including 107 companies with 15,164 participating employees, we received support for the hypothesized relationships. Our results contribute to current debates in the scientific literature on age and have important practical implications in light of the demographic changes faced by many companies. This research indicates to both researchers and practitioners that it is not employees' chronological age but their subjective age, a factor that can be influenced, which drives organizational performance outcomes.

The aim of this study was to evaluate whether an interdisciplinary, multifaceted oral health education program delivered to pediatric nurse practitioner students at the University of California, San Francisco, would improve their knowledge, confidence, attitudes, and behaviors regarding the provision of oral health assessments, consultations, referrals, and services to young children during well-child visits. Thirty pediatric nurse practitioner students were included in the study. Participants completed a written survey before and after receiving an interdisciplinary educational intervention that included didactic education, simulation exercises, and clinical observation by a pediatric dental resident. Between pre-intervention and post-intervention, a significant improvement was seen in the pediatric nurse practitioners’ knowledge of oral health topics (p<0.001), confidence when providing oral health counseling (p<0.001), and attitudes about including oral health counseling in their examinations (p=0.006). In the post-intervention survey, 83 percent of the subjects reported having incorporated oral examinations into their well-child visits. Our study suggests that providing an interdisciplinary oral health educational program for pediatric nurse practitioner students can improve their knowledge, confidence, attitudes, and behaviors regarding the incorporation of oral health care services during routine well-child visits.

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

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

Objective. Pain control is an essential goal in the management of critical children. Narcotics are the mainstay for pain control. Patients frequently need escalating doses of narcotics. In such cases an adjunctive therapy may be beneficial. Dextromethorphan (DM) is NMDA receptor antagonist and may prevent tolerance to narcotics; however, its definitive role is still unclear. We sought whether dextromethorphan addition could decrease the requirements of fentanyl to control pain in critical children. Design. Double-blind, randomized control trial (RCT). Setting. Pediatric multidisciplinary ICU in tertiary care center. Patients. Thirty-six pediatric patients 2–14 years of age in a multidisciplinary PICU requiring analgesia were randomized into dextromethorphan and placebo. The subjects in both groups showed similarity in most of the characteristics. Interventions. Subjects while receiving fentanyl for pain control received dextromethorphan or placebo through nasogastric/orogastric tubes for 96 hours. Pain was assessed using FLACC and faces scales. Measurements and Main Results. This study found no statistical significant difference in fentanyl requirements between subjects receiving dextromethorphan and those receiving placebo (p = 0.127). Conclusions. Dextromethorphan has no effect on opioid requirement for control of acute pain in children admitted with acute critical care illness in PICU. The registration number for this trial is NCT01553435. PMID:27867308

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.

Ageing is a natural phenomenon that has tremendous amount of control over normal physiological functions. Diabetes mellitus and ageing share common symptoms like stiffness and loss of functioning of tissues due to cross-liked proteins and free radicals. Glycated Haemoglobin (HbA1c) is often used as a stable cumulative index of glycemic control and has shown that even in non-diabetic adults, there is a steady increase in HbA1c levels with age. Aim of the study is to evaluate the strength of association of HbA1c with metabolic and cardiovascular ageing indices in subjects between the age group of 40 to 60 yrs. A total of 220 subjects, with (n=110) and without (n=110) diabetes were assessed for the metabolic and cardiovascular ageing indices. BMI, waist hip ratio, fat percentage, Fasting blood sugar and HbA1c were assessed as metabolic ageing indices. The cardiovascular ageing indices measured were resting heart rate, blood pressure and heart rate variability. Ageing indices were compared between subjects with and without diabetes using independent' t' test and showed that the T2DM group exhibit significant accelerated ageing as compared to that of the controls. Pearson's and partial correlation coefficient was used to assess the association of HbA1c with the ageing indices without and with controlling for chronological age, indicated that, strength of association of levels of HBA1c with cardiovascular and other metabolic indices of ageing is statistically significant. The study concludes that the tightness of glycemic control has a significant impact on the biological ageing process.

Many middle-aged women are affected by sleep disturbance. We investigated how subjective insomnia is associated with objective sleep parameters and other background characteristics. This cross-sectional study used baseline data obtained from 95 women aged 40-59 years who participated in another study assessing the effects of a dietary supplement. Participants wore an actigraph unit for 3 days to collect information concerning physical activities and objective sleep parameters and were then evaluated for body composition, cardiovascular parameters, and menopausal symptoms including insomnia and fatigue, and lifestyle factors. Stratifying Athens Insomnia Scale scores as low (0-5 points, control group) and high (≥ 6 points, subjective insomnia group), we sought to identify the parameters that are independently associated with subjective insomnia. Women with subjective insomnia (n = 30) had lower sleep efficiency than did the controls. They were also older; had more live births, lower height, higher body mass index, lower ankle brachial index, and more severe menopausal symptoms including fatigue; took more naps; smoked more cigarettes; and more of them were full-time workers. Multivariate logistic regression analysis revealed that low sleep efficiency (adjusted odds ratio, 1.44 per 1% decrease in sleep efficiency; 95% confidence interval 1.06-2.05) and fatigue assessed with Brief Fatigue Inventory (BFI) (adjusted odds ratio, 1.57 per 1-point increase in BFI score; 95% confidence interval 1.19-2.13) were independent contributors to subjective insomnia. Low sleep efficiency and feeling of fatigue were found to be independently associated with subjective insomnia in middle-aged women.

Glioblastoma multiforme (GBM) is the most common astrocytoma in adults and has a poor prognosis, with a median survival of about 12 months. But, it is rare in children. We report our experience on the pediatric population (20 years or younger) with GBM. Twenty-three patients with GBM who were treated at our hospital during 1990-2008 were evaluated. The mean age was 15.2 years, and the majority of them (14/23) were male. All had received radiotherapy and some had also received chemotherapy. The mean survival was 16.0 months. Two cases survived more than 5 years. Age, radiation dose and performance status were significantly related to survival. GBM in pediatric patients were not very common in our center, and prognosis was unfavorable.

Data are conflicting regarding the effect of professional staff attire on children at pediatric dental clinics. To compare the preferences of children and their parents in three countries, regarding the gender and attire of pediatric dentists. A multi-centered study was conducted in pediatric dental clinics in Israel (N=100), Uruguay (N=270) and Spain (N=200). Children, aged 4-12 years, and their parents were asked to choose the pediatric dentist they preferred from 5 pictures of the same male and 5 pictures of the same female, in different attire. In Israeli clinics, where half of the pediatric dentists were male, and they wore white coats or casual attire, these were preferred by children, with no preference regarding the dentist's gender. In Spain, where the majority of dentists were females, wearing surgical scrubs, children preferred female dentists with this attire. In Uruguay, where female dentists wore surgical or pediatric scrubs, these were preferred by children. Parents more often selected female than male dentists; they preferred pediatric scrubs for their children's dentists more often than their children preferred such attire. Children's preferences for the attire of pediatric dentists reflected the common wearing apparel for dentists at the clinics they attended.

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.

Vulvovaginitis accounts for 25% of all pediatric gynecology consultations. To assess the etiology of vulvovaginitis based on age and Tanner staging of breast development. Descriptive, cross-sectional study conducted between January 1st and December 31st, 2011. Patients with vulvovaginitis were assessed based on two outcome measures: age group (GI: 0 to 8.9 years old, GII: 9 to 15.9 years old, and GIII: 16 to 18 years old), and the Tanner staging of breast development (I, II-III, IV-V). Results. Two hundred and twenty-nine patients were included, 78 girls in the GI group, 134 in the GII group, and 17 in the GIII group; 81 girls were classified as TI, 36 as TII-III, and 112 as TIV-V based on Tanner staging. Shigella and Oxyuris were the most commonly found etiologic agents in younger girls. Candida albicans, other Candida species, Gardnerella and Ureaplasma urealyticum were the germs most commonly observed in older patients. Oxyuris was predominant in prepubertal girls, while Candida albicans, in postpubertal girls. Hormonal influence was more relevant than the patient's age in terms of vulvovaginitis etiology.

Pediatric neurocritical care.

PubMed

Murphy, Sarah

2012-01-01

Pediatric neurocritical care is an emerging multidisciplinary field of medicine and a new frontier in pediatric critical care and pediatric neurology. Central to pediatric neurocritical care is the goal of improving outcomes in critically ill pediatric patients with neurological illness or injury and limiting secondary brain injury through optimal critical care delivery and the support of brain function. There is a pressing need for evidence based guidelines in pediatric neurocritical care, notably in pediatric traumatic brain injury and pediatric stroke. These diseases have distinct clinical and pathophysiological features that distinguish them from their adult counterparts and prevent the direct translation of the adult experience to pediatric patients. Increased attention is also being paid to the broader application of neuromonitoring and neuroprotective strategies in the pediatric intensive care unit, in both primary neurological and primary non-neurological disease states. Although much can be learned from the adult experience, there are important differences in the critically ill pediatric population and in the circumstances that surround the emergence of neurocritical care in pediatrics.

Pediatric Awake Craniotomy for Brain Lesions.

Awake craniotomy is a special method to prevent motor deficits during the resection of lesions that are located in, or close to, functional areas. Although it is more commonly performed in adult patients, reports of pediatric cases undergoing awake craniotomy are limited in the literature. In our clinic, where we frequently use awake craniotomy in adult patients, we performed this method in 2 selected pediatric cases for lesion surgery. At an early age, these 2 cases diagnosed with epilepsy presented cerebral lesions, but since the lesions enclosed functional areas, surgical resection was not regarded as a treatment option at this time. In these 2 pediatric cases, we successfully completed lesion surgery with awake craniotomy. The method and the techniques employed during surgery are presented concomitant with other reports in the literature. © 2016 S. Karger AG, Basel.

New Developments in the Prophylactic Drug Treatment of Pediatric Migraine: What Is New in 2017 and Where Does It Leave Us?

PubMed

Kacperski, Joanne; Bazarsky, Allyson

2017-08-01

Headaches in children are quite common; however, the study and characterization of headache disorders in the pediatric age group has historically been limited. Because of the lack of controlled studies on prophylactic treatment of headache disorders in this age group, the diagnosis of migraine rests on criteria similar those in adults. Likewise, data from adult studies is often inferred and applied to children. Although it appears that many preventives are safe in children, currently none are FDA or EMA approved for this age group. Consequently, many children who present to their primary care physicians with migraines do not receive any preventive therapy despite experiencing significant disability. Controlled clinical trials investigating the use of preventive medications in children have suffered from high placebo response rates. The shorter duration of headaches and other characteristic features seen in children are such that designing randomized controlled trials in this age group is more problematic and limiting. Treatment practices vary widely, even among specialists, due to the absence of evidence-based guidelines from clinical trials. The Childhood and Adolescent Migraine Prevention Study (CHAMP) was developed to examine the effectiveness of two of the most widely prescribed preventive medications for pediatric migraine and help narrow this gap. To date, it has been the largest enrolling study of its kind within the pediatric migraine world; its results and implications will be discussed and considered here. The CHAMP trial was discontinued early on account of futility and exhibited that neither of two preventive medications for pediatric migraine was more effective than placebo in reducing the number of headache days over a period of 24 weeks. Subjects in the amitriptyline and topiramate groups had higher rates of adverse events than those who had received placebo.

Increasing evidence supports a role for mitochondrial dysfunction in organ injury and immune dysregulation in sepsis. Although differential expression of mitochondrial genes in blood cells has been reported for several diseases in which bioenergetic failure is a postulated mechanism, there are no data about the blood cell mitochondrial transcriptome in pediatric sepsis. We conducted a focused analysis using a multicenter genome-wide expression database of 180 children ≤ 10 years of age with septic shock and 53 healthy controls. Using total RNA isolated from whole blood within 24 hours of PICU admission for septic shock, we evaluated 296 nuclear-encoded mitochondrial genes using a false discovery rate of 1%. A series of bioinformatic approaches were applied to compare differentially expressed genes across previously validated gene expression-based subclasses (groups A, B, and C) of pediatric septic shock. In total, 118 genes were differentially regulated in subjects with septic shock compared to healthy controls, including 48 genes that were upregulated and 70 that were downregulated. The top scoring canonical pathway was oxidative phosphorylation, with general downregulation of the 51 genes corresponding to the electron transport system (ETS). The top two gene networks were composed primarily of mitochondrial ribosomal proteins highly connected to ETS complex I, and genes encoding for ETS complexes I, II, and IV that were highly connected to the peroxisome proliferator activated receptor (PPAR) family. There were 162 mitochondrial genes differentially regulated between groups A, B, and C. Group A, which had the highest maximum number of organ failures and mortality, exhibited a greater downregulation of mitochondrial genes compared to groups B and C. Based on a focused analysis of a pediatric septic shock transcriptomic database, nuclear-encoded mitochondrial genes were differentially regulated early in pediatric septic shock compared to healthy controls, as well

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.

Injury is the most common cause of death in pediatric patients, with a large proportion related to head injury. The craniofacial region in children develops rapidly and at an early age, making the area more prominent compared with the remainder of the body, increasing the likelihood of injury. This article reviews the primary management of pediatric soft tissue injuries, including assessment, cleansing, surgical technique, anesthesia, and considerations for special wounds. The secondary management of pediatric facial injury is also discussed, including scar revision, management of scar hypertrophy/keloids, and staged surgical correction. Copyright © 2012 Elsevier Inc.

Objectives (1) Describe longitudinal trends in annual prevalence of hospital admission for pediatric acute otitis media (AOM) and complications of AOM (CAOM) since introduction of pneumococcal vaccination in 2000 and (2) describe the longitudinal trend of prevalence of hospital admission for pneumococcal meningitis in children with AOM-related diagnoses in the postvaccination era. Study Design Retrospective analysis of Kids' Inpatient Database from 2000 to 2012. Setting Community, nonrehabilitation hospitals. Subjects and Methods To determine annual prevalence of admission for AOM/CAOM, nationally weighted frequencies of children aged <21 years with acute suppurative otitis media, acute mastoiditis, suppurative labyrinthitis, and/or acute petrositis were collected. The frequency of coexisting pneumococcal meningitis diagnoses among these patients was also collected. Trend analysis of prevalences of admission for AOM/CAOM and for pneumococcal meningitis occurring in the setting of AOM/CAOM from 2000 to 2012 was performed. Results Between 2000 and 2012, annual prevalence of admission for AOM/CAOM decreased from 3.956 to 2.618 per 100,000 persons ( P < .0001) (relative risk reduction 34%). Declines in admission prevalence were most pronounced in children <1 year of age (from 22.647 to 8.715 per 100,000 persons between 2000 and 2012, P < .0001) and 1 to 2 years of age (from 13.652 to 5.554 per 100,000 persons between 2000 and 2012, P < .0001). For all ages, the admission prevalence for pneumococcal meningitis and concomitant AOM/CAOM decreased (from 1.760 to 0.717 per 1,000,000 persons, P < .0001) over the study period. Conclusions The prevalence of hospital admission for pediatric AOM/CAOM has declined since the advent of pneumococcal vaccination. Admission rates for pneumococcal meningitis with AOM/CAOM have similarly declined.

The current study aimed to compare the efficacy and safety of 2 noninvasive respiratory support methods, which included helmet CPAP and high-flow nasal cannula (HFNC) in children with respiratory distress admitted to a pediatric intermediate care unit. This study was a prospective observational study conducted on children with respiratory distress (age 1-24 months) who were admitted to our acute and emergency operative unit. All included subjects were randomly treated with helmet CPAP or HFNC in a 1:1 fashion until their clinical picture, oxygen saturation, and arterial blood gas (ABG) parameters resolved. The efficiencies of helmet CPAP and HFNC were evaluated by breathing frequency, S pO 2 , ABG pH, ABG P aCO 2 , ABG P aO 2 , and P aO 2 /F IO 2 , recorded once at baseline and then after 1 and 6 h of treatment. Both noninvasive respiratory support modalities were compared with a control group of subjects with respiratory distress under standard therapeutic pharmaceutical protocols. We found that both helmet CPAP and HFNC were efficient in improving the clinical conditions of subjects with mild-to-moderate respiratory distress, although clinical response to helmet CPAP was more efficient and rapid compared with HFNC. Children who received respiratory support had a better clinical course in terms of hospitalization, days of intravenous rehydration therapy, and days of drug administration compared with the control group ( P < .001). Based on our knowledge, the present study is the first research comparing the effects of CPAP and HFNC in respiratory distress resolution in a pediatric intermediate care setting. It aims to identify the most efficient treatment to avoid pediatric ICU admissions and endotracheal intubation and reduce the administration of drugs and days of hospitalization.

To review current evidence of pharmacological options for managing pediatric obesity and provide potential areas for future research. A MEDLINE search (1966 to October 2014) was conducted using the following keywords: exenatide, liraglutide, lorcaserin, metformin, obesity, orlistat, pediatric, phentermine, pramlintide, topiramate, weight loss, and zonisamide. Identified articles were evaluated for inclusion, with priority given to randomized controlled trials with orlistat, metformin, glucagon-like peptide-1 agonists, topiramate, and zonisamide in human subjects and articles written in English. References were also reviewed for additional trials. Whereas lifestyle modification is considered first-line therapy for obese pediatric patients, severe obesity may benefit from pharmacotherapy. Orlistat is the only Food and Drug Administration (FDA)-approved medication for pediatric obesity and reduced body mass index (BMI) by 0.5 to 4 kg/m(2), but gastrointestinal (GI) adverse effects may limit use. Metformin has demonstrated BMI reductions of 0.17 to 1.8 kg/m(2), with mild GI adverse effects usually managed with dose titration. Exenatide reduced BMI by 1.1 to 1.7 kg/m(2) and was well-tolerated with mostly transient or mild GI adverse effects. Topiramate and zonisamide reduced weight when used in the treatment of epilepsy. Future studies should examine efficacy and safety of pharmacological agents in addition to lifestyle modifications for pediatric obesity. Lifestyle interventions remain the treatment of choice in pediatric obesity, but concomitant pharmacotherapy may be beneficial in some patients. Orlistat should be considered as second-line therapy for pediatric obesity. Evidence suggests that other diabetes and antiepileptic medications may also provide weight-loss benefits, but safety should be further evaluated. © The Author(s) 2014.

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 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.

Although there are similarities in the pathophysiology of acute respiratory distress syndrome in adults and children, pediatric-specific practice patterns, comorbidities, and differences in outcome necessitate a pediatric-specific definition. We sought to create such a definition. A subgroup of pediatric acute respiratory distress syndrome investigators who drafted a pediatric-specific definition of acute respiratory distress syndrome based on consensus opinion and supported by detailed literature review tested elements of the definition with patient data from previously published investigations. International PICUs. Children enrolled in published investigations of pediatric acute respiratory distress syndrome. None. Several aspects of the proposed pediatric acute respiratory distress syndrome definition align with the Berlin Definition of acute respiratory distress syndrome in adults: timing of acute respiratory distress syndrome after a known risk factor, the potential for acute respiratory distress syndrome to coexist with left ventricular dysfunction, and the importance of identifying a group of patients at risk to develop acute respiratory distress syndrome. There are insufficient data to support any specific age for "adult" acute respiratory distress syndrome compared with "pediatric" acute respiratory distress syndrome. However, children with perinatal-related respiratory failure should be excluded from the definition of pediatric acute respiratory distress syndrome. Larger departures from the Berlin Definition surround 1) simplification of chest imaging criteria to eliminate bilateral infiltrates; 2) use of pulse oximetry-based criteria when PaO2 is unavailable; 3) inclusion of oxygenation index and oxygen saturation index instead of PaO2/FIO2 ratio with a minimum positive end-expiratory pressure level for invasively ventilated patients; 4) and specific inclusion of children with preexisting chronic lung disease or cyanotic congenital heart disease.

An estimated 24 million people, or 11% of the North American population over 16 years of age, use the Internet. An estimated 40% of households have computers, and 37 million people have Internet access. The experience of three pediatric surgery Internet sites are reviewed to evaluate current practices and future potential of the Internet to practicing pediatric surgeons. The sites reviewed are the Pediatric Surgery Bulletin Board System (BBS), the Pediatric Surgery List Server, and the Pediatric Surgery Website. Statistics were collected at each site to characterize the number of users, traffic load, topics of interest, and times of peak use. There are currently 79 subscribers to the Pediatric Surgery BBS and 100 subscribers to the Pediatric Surgery List Server. The average user of the BBS is a young man who has placed an average of 52 calls to the BBS since joining. There have been 1413 Internet electronic mail messages sent. Twenty-five percent of the traffic has been related to clinical problems and 5% to research, teaching, and career issues. Traffic at this site has been increasing exponentially with most of the dialogue concentrated on clinical issues and problem cases. In a 3-month period the Pediatric Surgery Website received 16,270 hits. The most commonly accessed areas include an electronic mail directory, case studies, the job board, information on the pediatric surgical residency, and information on upcoming meetings. Pediatric surgeons are exploring the Internet and using available pediatric surgery resources. The scope of professional information available to pediatric surgeons on the Internet is still limited but is increasing rapidly. The Internet will impact the way physicians practice medicine through education and communication.

The population of children requiring home mechanical ventilation has evolved over the years and has grown to include a variety of diagnoses and needs that have led to changes in the care of this unique population. The purpose of this study was to provide a descriptive analysis of pediatric patients requiring home mechanical ventilation after hospitalization and how the evolution of this technology has impacted their care. A retrospective, observational, longitudinal analysis of 164 children enrolled in a university-affiliated home mechanical ventilation program over 26 years was performed. Data included each child's primary diagnosis, date of tracheostomy placement, duration of mechanical ventilation during hospitalization that consisted of home mechanical ventilator initiation, total length of pediatric ICU stay, ventilator settings at time of discharge from pediatric ICU, and disposition (home, facility, or died). Univariate, bivariate, and regression analysis was used as appropriate. The most common diagnosis requiring the use of home mechanical ventilation was neuromuscular disease (53%), followed by chronic pulmonary disease (29%). The median length of stay in the pediatric ICU decreased significantly after the implementation of a ventilator ward (70 d [30-142] vs 36 d [18-67], P = .02). The distribution of subjects upon discharge was home (71%), skilled nursing facility (24%), and died (4%), with an increase in the proportion of subjects discharged on PEEP and those going to nursing facilities over time ( P = 0.02). The evolution of home mechanical ventilation has allowed earlier transition out of the pediatric ICU and with increasing disposition to skilled nursing facilities over time. There has also been a change in ventilator management, including increased use of PEEP upon discharge, possibly driven by changes in ventilators and in-patient practice patterns.

This study aimed to evaluate age-related changes in laser-evoked potential (LEP) features, including habituation, via trigeminal and hand stimulation in a large group of healthy volunteers. We recorded the LEPs by right-hand stimulation in 237 healthy subjects and by stimulation of the right supraorbital zone in 170 cases. The subjects ranged in age from 7 to 72 years and were divided into six groups by age. At the trigeminal level, the N2 and P2 latencies were significantly shorter and the N2-P2 amplitude was significantly larger in the 7-17 age group than in the other groups. The N2-P2 amplitude of the responses evoked by hand stimulation was significantly larger in the 7-40 age range than in the older subjects. The N1 amplitude and latency were not significantly different among the groups. The N2-P2 habituation increased with age, but no significant changes among groups were revealed by the Bonferroni test. Trigeminal vertex LEPs have greater amplitudes and appear earlier in children, while a progressive age-related amplitude decrease characterizes the N2-P2 waves associated with hand stimulation. The N2-P2 habituation increases in older people. The N1 latency and amplitude seem to remain stable during ageing and are therefore potentially reliable and useful patterns for nociceptive system examination. Standardization of age-related changes in trigeminal and hand LEPs is possible and should improve their reliability in the objective assessment of pain pathways. © 2017 European Pain Federation - EFIC®.

Lymphocele is a well-known postoperative complication after kidney transplantation. The aim of this study was to analyze time trend incidence, risk factors, and outcome of post-transplant lymphocele in a large pediatric cohort. This is a retrospective single institution review of 241 pediatric kidney transplants performed from 2000 to 2013. Etiology of end-stage renal disease, recipient age and gender, transplant year, BMI percentile for age, type of dialysis, living/non-living related donor, acute rejection, and multiple transplantations were analyzed in association with lymphocele formation. Fourteen of 241 (5.81%) children developed a postoperative lymphocele. There has been a reduction in the incidence of lymphocele after 2006 (3.22% vs. 8.55%, p < 0.05). Significant risk factors for lymphocele were older age (≥11 yr), transplant before 2006, male gender, BMI percentile for age ≥95%, and multiple transplantations (p < 0.05). The one-yr graft survival was significantly reduced in the group with lymphocele compared with control (81.2% vs. 92.51%, p < 0.04). This is the first pediatric report showing the following risk factors associated with post-transplant lymphocele: age ≥11 yr, male gender, BMI for age ≥95%, and multiple transplantations. A lymphocele can contribute to graft loss in the first-year post-transplant. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

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.

After the introduction of flexible fiber optic endoscopy to pediatric gastroenterology in the 1970s, upper gastrointestinal (UGI) endoscopy can be performed for the diagnosis and treatment of all age groups of children. We review indications, contraindications, preparation of patients for the procedure, and details of diagnostic and therapeutic UGI endoscopy used in pediatric surgery. We also discuss potential complications of endoscopy. PMID:26566483

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

Emotional Intelligence Mediates the Relationship between Age and Subjective Well-Being.

Individuals' Subjective Well-being (SWB) increases as they grow older. Past literature suggests that emotional intelligence may increase with age and lead to higher levels of SWB in older adults. The primary purpose of the present study was to test whether emotional intelligence would mediate the relationship between age and SWB. A total of 360 Chinese adults (age range: 20 to 79 years old) participated in this study. They filled out questionnaires that assessed their age, life satisfaction (The Satisfaction with Life Scale), affective well-being (The Positive and Negative Affect Schedule), and emotional intelligence (The Wong and Law Emotional Intelligence Scale). Using Structural Equation Modeling, the mediation model was supported, χ(2) (75) = 194.21, p < .01; RMSEA = .07; CFI = .91. Emotional intelligence partially mediated the relationship between age and life satisfaction, and fully mediated the relationship between age and affective well-being. The findings suggest that older adults may use their increased emotional intelligence to enhance their SWB. © The Author(s) 2016.
