An increasing proportion of cancer patients are aged >65 years and many are aged >70 years. Treatment of the elderly with lung cancer has, therefore, become an important issue; so we performed a retrospective study of our patients to demonstrate how elderly patients with NSCLC are treated in real-life, clinical practice. All patients aged ≥70 years with NSCLC at our department were reviewed retrospectively. In total, 1059 patients (50.8% of all NSCLC patients). Of these patients, 243 (22.9%) received chemotherapy, 164 (70.4%) of whom were treated with a platinum doublet using carboplatin. Second- and third-line chemotherapy were given to 31.4% and 13.9% of patients, respectively. Median overall survival was 289 and 320 days for male and female patients, respectively. Patients with performance status (PS) 0 experienced significantly better survival than patients with PS1 or PS 2: 410, 314, and 204 days, respectively. Age was of less importance, with patients aged 70-79 years versus those aged ≥80 years. Treatment of elderly NSCLC patients with chemotherapy is feasible if they have a good PS and appears to prolong survival. In this study, we found no significant differences in survival either between age groups or genders.

Background: Utilization of health services is the actual attendance by the members of the public at health care facilities to receive care. Utilization, serves as an important tool for oral health policy decision-making. The aim of the present study was to retrospectively gauge and assess the utilization pattern of the dental treatments which was given in hospital for last 10 years. Materials and Methods: This retrospective infirmary based study was carried out at Sheri Kashmir Institute of Medical Sciences (SKIMS), Srinagar, Jammu and Kashmir, India. The yearly outpatient department (OPD) records for the utilization of specific dental treatment of a total of 103963 patients were assessed retrospectively from 2014 to 2003. Trend analysis was used to assess the trend of utilization of each speciality with best fitted linear trend lines. Results: The pattern of new patients has also shown a constant rise during the study period except for 2008 and 2009. The utilization of oral surgery speciality has shown a tremendous fall from 2003 to 2014 whereas the number of patients coming to periodontics and conservative dentistry has shown an increasing pattern. Conclusion: Utilization of oral health care has long been used as an indicator of oral health related behaviour of a population. In the present study it can be conclude that the outlook of the population under study has changed from blood and vulcanite dentistry outlook and is moving towards restorative dentistry. .

To determine the association between antibiotic exposure in the first year of life and the development of childhood asthma. Metaanalysis of observational studies retrieved through systematic search of all available electronic data sources. Studies included in the metaanalyses were those with populations exposed to one or more courses of antibiotics during the first year of life, and asthma diagnosis was defined as diagnosis by a physician between the age of 1 to 18 years. Retrospective and prospective studies published in the English-language literature from 1966 to present. Eight studies (four prospective and four retrospective) examined the association between exposure to at least one course of antibiotics and development of childhood asthma. The total number of subjects for the analysis comparing exposure to at least one antibiotic to no exposure in the first year of life was 12,082 children and 1,817 asthma cases. In the dose-response analysis, we included data from a total of 27,167 children and 3,392 asthma cases. The pooled odds ratio (OR) for the eight studies was 2.05 (95% confidence interval [CI], 1.41 to 2.99). The association was significantly stronger in the retrospective studies (OR, 2.82; 95% CI, 2.07 to 3.85) than the prospective studies (OR, 1.12; 95% CI, 0.88 to 1.42). Five of the eight studies examined whether the association was related to the number of courses of antibiotics taken in the first year of life. The overall OR for the dose-response analysis was 1.16 (95% CI, 1.05 to 1.28) for each additional course of antibiotics; however, this association was not significantly stronger in the retrospective studies (OR, 1.37; 95% CI, 1.18 to 1.60) relative to the prospective studies (OR, 1.07; 95% CI, 0.95 to 1.20). Exposure to at least one course of antibiotics in the first year of life appears to be a risk factor for the development of childhood asthma. Because of the limitations of the studies conducted to date, additional large-scale, prospective studies are needed to confirm this potential association.

Objective. We examined the extent to which retrospective proxy reports of well-being mirror participant self-reports at 12–24 months before death and how proxy reports of well-being change over the last year of life. We also explored the role of sociodemographic, cognitive, and health factors of both participants and proxies in moderating such associations. Method. We used retrospective proxy ratings obtained in the German Socio-Economic Panel Study (N = 164; age at death = 19–99 years). Results. Results revealed moderate agreement between self- and proxy reports (r = .42), but proxies, on average, overestimated participants’ life satisfaction by two thirds of a scale point on a 0–10 scale (or 0.4 SD). Discrepancies were particularly pronounced when proxies themselves reported low life satisfaction. Over the last year of life, participants were viewed to have experienced declines in life satisfaction (−0.54 SD). Declines were stronger for ill participants and proxies who reported low life satisfaction. Discussion. Results qualify theoretical expectations and empirical results based on self-report data that are typically available 1 or 2 years before death. We discuss that retrospective proxy reports in panel surveys can be used as a hypothesis-generating tool to gather insights into late life. PMID:23766436

Evaluation of 1-year safety profile of intravitreal ranibizumab 0.5 mg in neovascular age-related macular degeneration (NV-AMD) within routine clinical practice. The LUMINOUS programme comprises a prospective observational study assessing ranibizumab 'real-world' safety and clinical effectiveness across licensed indications worldwide and an annual retrospective pooled safety analysis from completed NV-AMD ranibizumab registries. 1-year data from four European registries are available. This retrospective pooled safety analysis assessed 1-year incidence rates for safety events of particular interest (key ocular or systemic events possibly related to the injection procedure or vascular endothelial growth factor inhibition) together with treatment exposure. Patients were treated according to local protocols within the ranibizumab licence. Data of 4444 patients from registries in Germany (n=3470), the Netherlands (n=243), Belgium (n=260) and Sweden (n=471) were retrospectively pooled. Between 70.4% and 84.4% of enrolled patients completed 1 year of follow-up. Most frequent overall ocular events of particular interest were retinal pigment epithelial tears (27 patients; <1%) and intraocular pressure-related events (12 patients; <0.3%). Most frequent non-ocular event of particular interest was stroke (19 patients; 0.4%); annual incidence of stroke was low across all registries (0.0-0.5%). Ranibizumab demonstrated favourable 1-year safety profile for NV-AMD in this routine clinical practice sample, consistent with previous reported trial data. Additional data from a larger patient population are needed to better describe the long-term safety profile of ranibizumab in routine clinical practice and further evaluate risk for infrequent but serious events in 'real-life' settings. The 5-year LUMINOUS prospective observational study will address this need.

Objectives. This study investigated retrospective validation of a prospective surveillance system for unexplained illness and death due to possibly infectious causes. Methods. A computerized search of hospital discharge data identified patients with potential unexplained illness and death due to possibly infectious causes. Medical records for such patients were reviewed for satisfaction of study criteria. Cases identified retrospectively were combined with prospectively identified cases to form a reference population against which sensitivity could be measured. Results. Retrospective validation was 41% sensitive, whereas prospective surveillance was 73% sensitive. The annual incidence of unexplained illness and death due to possibly infectious causes during 1995 and 1996 in the study county was conservatively estimated to range from 2.7 to 6.2 per 100 000 residents aged 1 to 49 years. Conclusions. Active prospective surveillance for unexplained illness and death due to possibly infectious causes is more sensitive than retrospective surveillance conducted through a published list of indicator codes. However, retrospective surveillance can be a feasible and much less labor-intensive alternative to active prospective surveillance when the latter is not possible or desired. PMID:11499106

A retrospective nested case-control study was designed to explore whether freshman year mental health status and level of adaptation are predictors of Internet addiction. The study cohort was 977 college students at a university in northwest China. In the first college year, the students' mental health status and adaptation level were assessed using the Chinese College Student Mental Health Scale (CCSMHS) and the Chinese College Student Adjustment Scale (CCSAS). In the following 1-3 years, 62 Internet-addicted subjects were identified using Young's 8-item diagnostic questionnaire. Controls were matched for demographic characteristics. Using logistic regression analysis, freshman year mental health status, including factors such as somatization, anxiety, depression and self-contempt, and freshman year adaptive problems were found to be causal factors and predictors of Internet addiction. Freshman with features of depression, learning maladaptation and dissatisfaction could be an important target-intervention population for reducing Internet addiction. © 2013 Elsevier Ireland Ltd.

Overt hepatic encephalopathy (HE) is a major cause of significant morbidity and mortality in patients with liver cirrhosis. We examined the frequency and profile of the precipitating factors resulting in hospitalizations for overt HE. We conducted both retrospective and prospective studies to identify clinical precipitants of overt HE in patients with cirrhosis. The retrospective study patients were hospitalized at a large urban safety-net hospital, and the prospective study included the patients admitted at a liver transplant center. There were a total of 149 patients with cirrhosis and overt HE (91 males, mean age 55.3 ± 8.6 years) in the retrospective group and 45 patients (27 males, mean age 58.3 ± 8.2 years) in the prospective group of the study. The average MELD score was 16 ± 6.8 in the retrospective group and 22.7 ± 7.2 in the prospective group. Dehydration (46-76%), acute kidney injury (32-76%), lactulose nonadherence (about 50%), constipation (about 40%), and infections (20-42%) were the most frequently identified precipitants for hospitalization in retrospective and prospective groups. Multiple precipitants were identified in 60 (40.3%) patients in the retrospective group and 34 (76%) patients in the prospective group. Multiple concurrent precipitating factors were identified in the majority of patients with overt HE requiring hospitalization. Dehydration due to various causes was the most common precipitant of overt HE, followed by acute kidney injury (AKI), constipation, and infections. Prevention of dehydration, AKI, and constipation by close outpatient monitoring may be an effective measure to prevent hospitalization for overt HE in patients with cirrhosis.

To identify a possible connection between anaplastic large cell lymphoma and different types of breast implants. We conducted a retrospective evaluation of 296 breast tissues of 227 women with different breast implant types undergoing surgical revision or explantation between January 2000 and June 2015. Histological and selected immunohistochemical analyses of CD30-&ALK-1-markers of the breast capsules were performed. The womens' average age was 42.91±12.66 years (median: 43.83 years) during implantation and 51.40±11.40 years (median: 52.37 years) during revision or explantation of the implants. Average implant residing time was 8.49±8.90 years (median: 5.83 years). In 51% implantation was for reconstructive, in 48% for aesthetic reasons, in 1% for other reasons. At 59% the main reason for explantation or removal was capsular fibrosis (n = 173). In 296 breast capsules we could not find pathological lymphoma cells according to ALCL, retrospectively. In our study we detected high incidences of various cells in relationship to the implant's type and residing time, which will be published in further articles. We could not find ALCL-cells in breast capsules of explanted or revised breast implants during 2000-2015, retrospectively.There should be a heightened awareness of a possible relationship between the development of cancer and breast implants. To date there are case reports about a possible association between the development of ALCL and breast implants. The number of cases are few and our knowledge of the pathogenesis is little. Further investigation is needed to understand the possible link between breast implants and ALCL found in the breast.

Pancreatic ductal adenocarcinoma (PDAC) may present with acute and /or chronic pancreatitis due to pancreatic ductal obstruction causing diagnostic dilemma. The aim of this retrospective study was to investigate the outcome and prognosis of the patients of PDAC presenting with pancreatitis. From 1991 to 2009, 298 patients with PDAC that underwent surgical treatment were retrospectively studied and divided in two groups depending upon initial symptomatic presentation. Group A (n=254) comprised patients without pancreatitis while group B (n=44) patients presented with acute and/or chronic pancreatitis initially. All the patients in studied cohort were surgically treated. Mean age of group A was 63.1 years & for group B it was 62.9 years. Location of tumor was in head of the pancreas in 66.14% of group A patients (n=168) and 61.36% of group B patients (n=27). Although statistically insignificant, the patients in group B had overall better 5-year survival than the patients in group A (20% vs 15.9%). This retrospective study highlights the overall better survival of PDAC patients presenting with acute and/or chronic pancreatitis than those without as contrary to previous reports which stated the poor prognosis of PDAC patients if associated with underlying pancreatitis.

Retrospective studies on oral cancer patient profiles related to risk habits could provide etiologic clues for prevention in specific geographic areas. To study risk habit characteristics of oral cancer patients. A cross sectional retrospective case record study of oral cancer patients who reported during 1991-2000 to Karnataka Cancer Therapy and Research Institute, Hubli, India was conducted. Data on socio-demography, histopathology, site of cancer and risk habit profiles of the patients were recorded in a predesigned Performa by one calibrated examiner with internal validity checks. The 1,472 oral cancer patients constituted 11% of total cancer patients. Mean age of the patients was 55 years, ranging from 12-88, with a male: female ratio of 2:1. 1,110 (75%) oral cancer patients had risk habits, 55% were habituated for >10 years and 25% were habit free. 751(51%) patients had individual and 359(24%) had combined risk habits. Majority 59% were chewers of betel quid alone (17%)/betel quid with tobacco (42%); smokers were (31%) and alcohol users were (14%) of patients. Chewers of gutkha, khaini were more in <40 years and betel quid in >40 years. Risk habituates were highest (87%) in patients with cancer of buccal mucosa, commonly affected site attributed to chewing habit in (51%) of patients. The prevalence of oral cancer was higher among elderly males predominantly with risk habits of betel quid/tobacco chewing and smoking for more than 10 years.

A retrospective analysis of toxicity studies in dogs and impact on the chronic reference dose for conventional pesticide chemicals.

Prior to October 2007, the US Environmental Protection Agency (EPA) required both 13-week and 1-year studies in Beagle dogs be submitted in support of registration for pesticides. Following an extensive retrospective analysis, we (the authors) determined that the 1-year toxicity dog study should be eliminated as a requirement for pesticide registration. The present work presents this retrospective analysis of results from 13-week and 1-year dog studies for 110 conventional pesticide chemicals, representing more than 50 classes of pesticides. The data were evaluated to determine if the 13-week dog study, in addition to the long-term studies in two rodent species (mice and rats), were sufficient for the identification of no observed adverse effect levels (NOAELs) and lowest observed adverse effect levels (LOAELs) for the derivation of chronic reference doses (RfD). Only pesticides with adequate 13-week and 1-year duration studies were included in the present evaluation. Toxicity endpoints and dose-response data from 13-week and 1-year studies were compared. The analysis showed that 70 of the 110 pesticides had similar critical effects regardless of duration and had NOAELs and LOAELs within a difference of 1.5-fold of each other. For the remaining 40 pesticides, 31 had lower NOAELs and LOAELs in the 1-year study, primarily due to dose selection and spacing. In only 2% of the cases were additional toxic effects identified in the 1-year study that were not observed in the 13-week study and/or in the rodent studies. In 8% of the cases, the 1-year dog had a lower NOAEL and/or LOAEL than the 13-week study, but there would have been no regulatory impact if the 1-year dog study had not been performed because adequate data were available from the other required studies. A dog toxicity study beyond 13-weeks does not have significant impact on the derivation of a chronic RfD for pesticide risk assessment.

The aim of this retrospective study was to determine the clinical and the radiographic outcomes of dental implants placed in elderly people older than 65 years. In total, 902 implants in 346 patients (age: 65-89 years) were followed up for 2-17 years following the implant surgery. The survival rate of these implants was recorded and analyzed. Changes in marginal bone levels were also analyzed in serial radiographs, and Cox regression analysis for implant loss was performed. The survival rates were 95.39% and 99.98% in the implant- and patient-based analyses, respectively (involving a total of 29 implant failures), and the marginal bone loss at the implants was 0.17 ± 0.71 mm (mean ± SD). The number of failures was greatest in patients aged 65-69 years. The Cox regression with shared frailty analysis showed that implant loss was significantly greater in those aged 65-69 years than in those aged 70-74 years (P < 0.05), and it varied between specific implant systems. Within the limitations of this retrospective study, it was concluded that implant therapy can be successfully provided to elderly patients and that age alone does not seem to affect the implant survival rate. © 2016 John Wiley & Sons A/S.

2017-12-01

Although research often relies on retrospective affect self-reports, little is known about personality's role in retrospective reports and how these converge or deviate from affect reported in the moment. This micro-longitudinal study examines personality (Neuroticism, Extraversion) and emotional salience (peak and recent affect) associations with retrospective-momentary affect report discrepancies over different time frames. Participants were 179 adults aged 20-78 (M = 48.7 years; 73.7% Caucasian/White) who each provided up to 60 concurrent affect reports over 10 days, then retrospectively reported overall intensity of each affective state after 1 day and again after 1-2 months. Multilevel models revealed that individuals retrospectively overreported or underreported various affective states, exhibiting peak associations for high arousal positive and negative affect, recency associations for low arousal positive affect, and distinct personality profiles that strengthened over time. Individuals high in both Extraversion and Neuroticism exaggerated high arousal positive and negative affect and underreported low arousal positive affect, high Extraversion/low Neuroticism individuals exaggerated high arousal positive affect and underreported low arousal positive affect, and low Extraversion/high Neuroticism individuals exaggerated high and low arousal negative affect. This study is the first to identify arousal-specific retrospective affect report discrepancies over time and suggests retrospective reports also reflect personality differences in affective self-knowledge. © 2016 Wiley Periodicals, Inc.

Intracorneal ring segment implantation is an effective and safe method of visual improvement in patients with keratoconus. The aim of our study was to evaluate the long-term clinical outcomes after Keraring implantation for keratoconus in patients older than 40 years. Eleven eyes from 11 patients with keratoconus who underwent femtosecond laser-assisted Keraring implantation for keratoconus were included in this retrospective study. The uncorrected visual acuity (UCVA), corrected visual acuity, keratometric readings, central corneal thickness and thinnest corneal pachymetry were evaluated preoperatively and 6 months after the Keraring implantation. UCVA, BCVA and keratometric readings improved at 6 months postoperatively. Our data showed significant keratometric amelioration and visual improvement after Keraring implantation for keratoconus in patients older than 40 years at 6 months postoperatively.

A retrospective study of 30 long-term survivors of cranial or craniospinal irradiation for intracranial space-occupying lesions has demonstrated physical and mental handicaps in the majority. This is most severe in those cases treated before the age of 11 years, and is not confined to those children having craniospinal or whole-brain irradiation. The mental handicap also appears to be progressive, but cannot be easily examined in this retrospective study. (auth)

Background. Malaria is a major public health problem in Ethiopia where an estimated 68% of the population lives in malarious areas. Studying its prevalence is necessary to implement effective control measures. Therefore, the aim of this study was to determine seven-year slide positive rate of malaria. Methods. A retrospective study was conducted at Metema Hospital from September 2006 to August 2012. Seven-year malaria cases data had been collected from laboratory registration book. Results. A total of 55,833 patients were examined for malaria; of these, 9486 (17%) study subjects were positive for malaria. The predominant Plasmodium species detected was P. falciparum (8602) (90.7%) followed by P. vivax (852) (9%). A slide positive rate of malaria within the last seven years (2006-2012) was almost constant with slight fluctuation. The age groups of 5-14 years old were highly affected by malariainfection (1375) (20.1%), followed by 15-29 years old (3986) (18.5%). High slide positive rate of malaria occurred during spring (September-November), followed by summer (June-August). Conclusion. Slide positive rate of malaria was high in study area. Therefore, health planners and administrators should give intensive health education for the community.

The purpose of this retrospective study was to describe the magnetic resonance imaging (MRI) features of Poly Implant Prothèse (PIP) hydrogel implants in a group of 64 patients and to assess the incidence of rupture, compared to other clinical trials. In this double-center study, we retrospectively reviewed the data sets of 64 consecutive patients (mean age, 43±9 years, age range, 27-65 years), who underwent breast MRI examinations, between January 2008 and October 2013, with suspected implant rupture on the basis of clinical assessment or after conventional imaging examination (either mammography or ultrasound). All patients had undergone breast operation with bilateral textured cohesive gel PIP implant insertion for aesthetic reasons. The mean time after operation was 8 years (range, 6-14 years). No patients reported history of direct trauma to their implants. At the time of clinical examination, 41 patients were asymptomatic, 16 complained of breast tenderness and 7 had clinical evidence of rupture. Normal findings were observed in 15 patients. In 26 patients there were signs of mild collapse, with associated not significant peri-capsular fluid collections and no evidence of implant rupture; in 23 patients there was suggestion of implant rupture, according to breast MRI leading to an indication for surgery. In particular, 14 patients showed intra-capsular rupture, with associated evidence of the linguine sign in all cases; the keyhole sign and the droplet signs were observed in 6 cases. In 9 patients there was evidence of extra-capsular rupture, with presence of axillary collections (siliconomas) in 7 cases and peri-prosthetic and mediastinal cavity siliconomas, in 5 cases. The results of this double center retrospective study, confirm the higher incidence (36%) of prosthesis rupture observed with the PIP implants, compared to other breast implants.

Objective The present study was aimed at investigating bone involvement secondary to rotator cuff calcific tendonitis at ultrasonography. Materials and Methods Retrospective study of a case series. The authors reviewed shoulder ultrasonography reports of 141 patients diagnosed with rotator cuff calcific tendonitis, collected from the computer-based data records of their institution over a four-year period. Imaging findings were retrospectively and consensually analyzed by two experienced musculoskeletal radiologists looking for bone involvement associated with calcific tendonitis. Only the cases confirmed by computed tomography were considered for descriptive analysis. Results Sonographic findings of calcific tendinopathy with bone involvement were observed in 7/141 (~ 5%) patients (mean age, 50.9 years; age range, 42-58 years; 42% female). Cortical bone erosion adjacent to tendon calcification was the most common finding, observed in 7/7 cases. Signs of intraosseous migration were found in 3/7 cases, and subcortical cysts in 2/7 cases. The findings were confirmed by computed tomography. Calcifications associated with bone abnormalities showed no acoustic shadowing at ultrasonography, favoring the hypothesis of resorption phase of the disease. Conclusion Preliminary results of the present study suggest that ultrasonography can identify bone abnormalities secondary to rotator cuff calcific tendinopathy, particularly the presence of cortical bone erosion.

Postweaning multisystemic wasting syndrome (PMWS) is considered a multifactorial emerging disease of which Porcine circovirus-2 (PCV-2) is the necessary infectious cause. However, retrospective studies have shown that PMWS is not a new disease and that PCV-2 has been circulating in pig farms for years. Most of these studies were performed in Europe and Asia; only a few were performed in North or South America. A PCV-2 retrospective serological survey was carried out with 659 serum samples collected from pigs in Mexico between 1972 and 2000. Serological analyses were performed with an immunoperoxidase monolayer assay (IPMA). The overall prevalence of PCV-2 antibodies was 59% (387/659); the prevalence was 27% (24/90) for the period from 1972–1979; 44% (74/169) from 1980–1989, and 72% (289/400) from 1990–2000. Antibodies to PCV-2 were detected in at least 1 pig from all tested years since 1973. This study shows evidence of enzootic PCV-2 infection in Mexico for many years before the first description of PMWS in the country (in 2001), further supporting results obtained in other parts of the world. To date, this study provides the earliest evidence of PCV-2 infection in the North and South American continents. PMID:19337391

2015-01-01

Decompressive hemicraniectomy (DHC) after space-occupying strokes among patients older than 60 years has been shown to reduce mortality rates but at the cost of severe disability. There is an ongoing debate about what could be considered an acceptable outcome for these patients. Data about retrospective consent to the procedure after lengthy time periods are lacking. This study included 79 consecutive patients who underwent DHC during a 7.75-year period. Surviving patients were assessed for functional and psychological outcome, quality of life (QoL) and retrospective consent for the procedure. Patients younger than 60 years were compared with older patients. Of our 79 patients, 44 were younger than 60 years (median 50 years, interquartile range (IQR) 19-59 years) and 35 were older (median 68 years, interquartile range 60-87 years). The 30-day mortality rate was higher for the older group, but the difference was not statistically significant. Functional outcome was significantly better in the younger group: 31% of the patients in this group vs. 10% in the older group had a modified Rankin Scale score of 0-3 (p = 0.046). The mean National Institutes of Health Stroke Scale score was 17 ± 14 for the younger group and 29 ± 15 for the older group (p = 0.002). On the 36-Item Short Form Health Survey, with the exception of the item 'General health', the older group reported higher values for all items, with statistically significant differences between the 2 groups on the items 'Role limitation emotional' (p = 0.0007) and 'Vitality' (p = 0.02). In the younger group, 29% of patients retrospectively declined consent for DHC opposed to 0% of patients in the older group (p = 0.07). Despite impaired functional outcome after DHC, indicators of QoL and retrospective consent are higher for patients older than 60 years over the long term. This finding should be taken into account by those who counsel patients and caregivers with regard to this serious procedure. © 2015 S. Karger AG, Basel.

To report the prevalence of impacted third molars according to the age, gender and type among Saudi population. This retrospective study involved 3800 panoramic radiographs of subjects aged 18 to 45 years who presented to the College of Dentistry, King Khalid University, Abha, Kingdom of Saudi Arabia for oral care during the period from February 2009 to February 2011. Data collected was entered into a spreadsheet (Excel 2000; Microsoft, US) and analyzed using Statistical Package for Social Sciences (SPSS) version 16.0. A total of 713 impacted teeth were identified (18.76%) (p=0.003). The male to female ratio with impacted third molars was 604:109 (5.54:1) and the ratio of patients with impacted teeth was (5:1). Age group 1 (i.e., 20 to 25 years)had the highest prevalence of third molar tooth impaction (64.5%) and this decreased with increasing age. Incidence of tooth impaction is higher in the mandible than in maxilla. Males had a higher incidence of third molar impaction as compared to the females. Highest incidence is found in the age group of 20-25 years. Mesio-angular impaction was the most predominant type. How to cite this article: Syed KB, Kota Z, Ibrahim M, Bagi MA, Assiri MA.

In the past, immunogenicity of hepatitis A and B vaccines needed to be questioned in persons of advanced age, especially in those of 40 years and older. We performed a comparative multicenter prospective and retrospective study with the combined hepatitis A and B vaccine Twinrix to identify factors influencing the results of the vaccination in a population of all age groups. Out of 489 subjects enrolled, 241 were vaccinated in a prospective study (group 1) and 248 subjects in a retrospective study (group 2) in 17 German centers with median age of 40.1 (14-79) years. Following three applications of the combined hepatitis A/B vaccine we found 96.2% with protective antibodies against HAV and 88.7% were protected against HBV. With increasing age the subjects developed decreasing anti-HBs antibody levels whereas the seroprotection rate was significantly reduced by age (p < 0.05) in the retrospective study group only. Subjects with arterial hypertension and thyroid disease showed significantly decreased protection rates. The timing of the HBV antibody control seems to be important especially in low-responders because protective antibodies may drop below the detection limit within some month. The combined hepatitis A and B vaccine Twinrix proved to be highly effective against HBV, although antibody concentrations and seroprotection rates decreased with increasing age.

A retrospective analysis of oral cysts that were seen over an 11-year period in children at a dental institution in Nigeria was carried out. In general, oral cysts accounted for only 2.6% of the total biopsied lesions during the period under review. The most common oral cysts were the mucous retention cysts, the gingival cysts of infants and the dentigerous cyst. The commonest sites were the maxilla, the mandible and the floor of the mouth respectively and there was no significant difference in sex preference. Most of the cases were seen in the age group 11-16 years while the least was in the group aged 6-10 years.

increasingly, reflection is highlighted as integral to core practice competencies but empirical research into the relationship between reflection and performance in the clinical workplace is scarce. this study investigated the relationship between reflection ability and clinical performance. we designed a cross-sectional and a retrospective-longitudinal cohort study. Data from first, second and third year midwifery students were collected to study the variables 'clinical performance' and 'reflection ability'. Data were analysed with SPSS for Windows, Release 20.0. Descriptive statistics, Pearson׳s Product Moment Correlation Coefficients (r) and r² values were computed to investigate associations between the research variables. the results showed a moderate observed correlation between reflection ability and clinical performance scores. When adopting a cross-sectional perspective, all correlation values were significant (p<0.01) and above 0.4, with the exception of the third year correlations. Assuming perfect reliability in the measurement, the adjusted correlations, for year 2 and year 3 indicated a high association between reflection ability and clinical performance (>0.6). The results based on the retrospective-longitudinal data set explained a moderate proportion of the variance after correction for attenuation. Finally, the results indicate that 'reflection ability' scores of earlier years are significant related with 'clinical performance' scores of subsequent years. These results suggest that (1) reflection ability is linked to clinical performance; (2) that written reflections are an important, but not the sole way to assess professional competence and that (3) reflection is a contributor to clinical performance improvement. the data showed a moderate but significant relationship between 'reflection ability' and 'clinical performance' scores in clinical practice of midwifery students. Reflection therefore seems an important component of professional competence. Copyright © 2014 Elsevier Ltd. All rights reserved.

Aim of this exploratory study was to investigate whether a retrospective assessment of oral health-related quality of life (OHRQoL) using the Oral Health Impact Profile (OHIP) is susceptible to bias such as implicit theory of change and cognitive dissonance. In this prospective clinical study, a sample of 126 adult patients (age 17-83 years, 49% women) requiring prosthodontic treatment was consecutively recruited. The OHRQoL was assessed using the 49-item OHIP at baseline and at follow-up. Additionally, patients were asked at follow-up to retrospectively rate their oral health status at baseline (retrospective pretest or then-test) and the change in oral health status using a global transition question. Furthermore, patients' ratings of overall oral health and general health were used as validity criteria for the OHRQoL assessments. Response shift was calculated as the difference between the initial and retrospective baseline assessments. Baseline and retrospective pretest did not differ substantially in terms of internal consistency and convergent validity. Response shift was more pronounced when patients perceived a large change in OHRQoL during treatment. Retrospective pretests were more highly correlated with the baseline than with the follow-up assessment. Findings suggest that retrospective assessments of OHRQoL using the OHIP-49 are susceptible to bias. Cognitive dissonance is more likely to appear as a source of bias than implicit theory of change.

Firearm injuries (FI) are the most common cause of death among military personnel. In this study, postmortem examination and autopsy records of deaths resulting from firearm injuries recorded in the Department of Forensic Medicine of Gulhane Military Medical Academy between 1993-2010 were examined retrospectively. We evaluated the characteristics of 153 firearm deaths accounting for 36.6% of all medical-legal autopsies. The cases included 152 men (99.3%) and 1 woman (0.7%). The mean age of the cases was 23.1 years (±4.7; range, 20-43 years). The manner of death was determined in all cases with 41.8% of cases identified as suicide and 39.9% as homicide. The most common sites of firearm entrance wounds were the head and neck region (n=109, 71.2%), the chest (n=26, 17%), or the abdomen (n=14, 9.2%). The type of firearm was not clear in most cases. In conclusion, complete forensic and medical records will facilitate the rapid and accurate conclusion of the legal process and will enhance future retrospective studies.

A retrospective analysis of the added value of 1-year dog studies in pesticide human health risk assessments.

The 1-year dog toxicity study is no longer required by certain pesticide regulatory jurisdictions, including the United States and the European Union. Health Canada's Pest Management Regulatory Agency (PMRA) examined its current requirement for this study to determine if it could be refined or eliminated. A retrospective analysis was conducted to examine the impact of the 1-year dog study on human health risk assessment. The Acceptable Daily Intake (ADI), a measure of the amount of a pesticide in food that can be ingested on a daily basis over a lifetime without an appreciable health risk, was the metric for this analysis. For 143 pesticides evaluated by the PMRA between 2008 and 2015, the supporting toxicology databases were examined to determine if other toxicology studies were protective of the findings in the 1-year dog study. When this criterion was not met, further investigation was undertaken to determine the potential impact of not having the 1-year dog study. For most of the pesticides, effect levels in the 1-year dog study were not substantially different from those in other toxicology studies, when considering factors such as dose-spacing and known experimental variability. The results of this analysis suggest that absence of the 1-year dog study would have minimal impact on the assessment of human health risk. Therefore, Health Canada's PMRA has removed the routine requirement for the 1-year dog study from its pesticide data requirements.

The increasing use of commercial motorcycle as mode of transportation in urban cities in Nigeria has become important source of morbidity and mortality. This is coupled with poor helmet use, narrow roads, increasing traffic, and poor licensing of the motorcycle riders. The objectives of this study are to determine the pattern of injuries following accident involving motorcycles, the mortality rate, and the immediate causes of mortality. This is a combined retrospective and prospective study spanning over 2 years (1 year each). Patient's records were retrieved to collate data for the retrospective study while all the patients presenting to the casualty unit of Jos University Teaching Hospital following involvement in motorcycle accidents between April 2006 and March 2007 were selected for the study. Out of 485 motorcycle injured patients, 295 and 190 were recruited from the retrospective and prospective study respectively. The male: female (M: F) ratio was 4.8:1. The ages ranged from 2.5 to 84 years with a peak at 21-30 years. The total number of injuries was 559 with 443 patients singly injured and 42 patients multiply traumatized. Head injury (40.1%) was the most frequently occurring injury followed closely by extremity injuries (38.1%). None of the patients wore protective helmet. Thirty-six (36) mortalities (7.4%) were recorded and all dead patients had head injuries. All deaths occurred within 24 h. Head injury represents a common cause of morbidity and mortality following motorcycle injuries in our environment. Therefore, strict enforcement of helmet laws from May 10, 2010 may reduce morbidity and mortality.

The major aims of this study were to identify factors that may predict the diagnostic conversion from major depressive disorder (MDD) to bipolar disorder (BP) and to evaluate the predictive performance of the bipolar spectrum disorder (BPSD) diagnostic criteria. The medical records of 250 patients with a diagnosis of MDD for at least 5 years were retrospectively reviewed for this study. The diagnostic conversion from MDD to BP was observed in 18.4% of 250 MDD patients, and the diagnostic criteria for BPSD predicted this conversion with high sensitivity (0.870) and specificity (0.917). A family history of BP, antidepressant-induced mania/hypomania, brief major depressive episodes, early age of onset, antidepressant wear-off, and antidepressant resistance were also independent predictors of this conversion. This study was conducted using a retrospective design and did not include structured diagnostic interviews. The diagnostic criteria for BPSD were highly predictive of the conversion from MDD to BP, and conversion was associated with several clinical features of BPSD. Thus, the BPSD diagnostic criteria may be useful for the prediction of bipolar diathesis in MDD patients. Copyright © 2014 Elsevier B.V. All rights reserved.

2006-09-01

The rising prevalence of pediatric type 2 diabetes mellitus (DM2) and non-adherence to diabetes regimens pose challenges to obtaining optimal control. This study evaluated factors that may impact glycemic control (HbA1c): age, Tanner stage, body mass index (BMI), total daily insulin (TDD), metformin dose (MET), activity level, frequency of clinic visits and adherence. One-year data from 72 patients (ages 8.6-17.8 years) were collected retrospectively. From that sample, 57 patients who continued to attend clinic for the entire year were assessed and divided into optimal and suboptimal HbA1c control groups. All factors measured were similar in the two groups, except for lower initial and 1.0-year HbA1c, TDD, and rates of missing MET and insulin in the optimal HbA1c control group. Initial glycemic status and adherence rate predicted metabolic control at one year. Early identification of DM2 may improve metabolic outcome, which may improve medical regimen adherence.

Ninety percent of the lesions resulting from diving injuries affect the cervical spine and are potentially associated with spinal cord injuries. The objective is to determine the most frequent lesion mechanisms. Evaluate the therapeutic alternatives and the biomechanical evolution (kyphotic deformation) of diving-induced cervical spine injuries. Define epidemiological characteristics of diving injuries. A retrospective analysis over a period of 10 years was undertaken for patients admitted to the Department of Neurosurgery of Montpellier, France, with cervical spinal injuries due to a diving accident. Patients were re-evaluated and clinical and radiological evaluation follow-ups were done. This study included 64 patients. Cervical spine injuries resulting from diving predominantly affect young male subjects. They represent 9.5% of all the cervical spine injuries. In 22% of cases, patients presented severe neurological troubles (ASIA A, B, C) at the time of admission. A surgical treatment was done in 85% of cases, mostly using an anterior cervical approach. This is a retrospective study (type IV) with some limitations. The incidence of diving injuries in our region is one of the highest as compared to reports in the literature. Despite an increase of our surgical indications, 55% of these cases end up with a residual kyphotic deformation but there is no relationship between the severity of late vertebral deformity and high Neck Pain and Disability Scale (NPDS) scores.

A retrospective exposure assessment was performed for use in a health outcomes study of a facility manufacturing circuit boards, business machines, and other equipment during the years 1969–2002. A matrix was developed identifying chemical use by department-year based on company-provided information. Use of six chemical agents (fiberglass, lead, methylene chloride, methyl chloroform, perchloroethylene, and trichloroethylene) and six chemical classes (acid-base, aromatic hydrocarbons, chlorinated hydrocarbons, other hydrocarbons, chlorofluorocarbons, and metals), and general (including unspecified) chemicals was identified. The matrix also contained an assignment for each department-year categorizing the potential for use of chemicals as negligible, intermittent/incidental, or routine. These department-based exposure matrix data were combined with work history data to provide duration of potential chemical use for workers. Negligible, intermittent/incidental or routine extent-of-chemical-use categories comprised 42.6%, 39.4%, and 17.9%, respectively, of total person-years of employment. Cumulative exposure scores were also developed, representing a relative measure of the cumulative extent of potential exposure to the six chemical agents, six chemical classes, and general (including unspecified) chemicals. Additionally, the study period was divided into manufacturing eras showing trends in chemical use, and showing that process use of trichloroethylene and methylene chloride ended in the mid-1980s and the mid-1990s, respectively. This approach may be useful in other assessments addressing a variety of chemicals, and with data constraints common to retrospective chemical exposure studies. PMID:24224613

Objective Weight changes may be an important indicator of an ongoing pathological process. Retrospective self-report might be the only possibility to capture prior weight. The objective of the study was to evaluate the accuracy of retrospective recall of body weight in old age and factors that might predict accuracy. Design and Methods In 2007, 646 participants (mean age, 71.6 years) of the Swedish Adoption/Twin Study of Aging (SATSA) answered questions about their present weight and how much they weighed 20-years ago. Of these, 436 had self-reported their weight twenty years earlier and among these 134 had also had their weight assessed at this time point. Results Twenty year retrospectively recalled weight underestimated the prior assessed weight by −1.89 ± 5.9 kg and underestimated prior self-reported weight by −0.55 ± 5.2 kg. Moreover, 82.4% of the sample were accurate within 10%, and 45.8% were accurate within 5% of their prior assessed weights; similarly, 84.2% and 58.0 % were accurate within 10% and 5% respectively, for prior self-reported weight. Current higher body mass index and preferences of reporting weights ending with zero or five was associated with an underestimation of prior weight, while greater weight change over 20 year, and low Mini-Mental State Scores (MMSE) (<25) led to an overestimation of prior weight. Conclusions Recalled weight comes close to the assessed population mean, but at the individual level there is a large variation. The accuracy is affected by current BMI, changes in weight, end-digit preferences, and current cognitive ability. Recalled weight should be used with caution. PMID:23913738

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

There is an increasing trend for administration of invasive radiological interventions, laparoscopic surgery, and transplantation procedures in recent years, and determining the vascular variations prior to these procedures is crucially important. Celiacomesenteric trunk (CMT) is among these variations. This study aimed to retrospectively evaluate this rare anomaly by computed tomography (CT). A total of 1000 CT angiography images were analyzed retrospectively, and the patients with mesenteric and celiac arteries arising from the abdominal aorta with a single root were identified. The level that CMT arose, and its branching patterns were determined individually for all patients. Ten patients (6 males and 4 females) with a mean age of 50.2 years (17-87 years) had CMT in CT images. The knowledge of variations in the CMT prior to vascular or laparoscopic interventions will contribute to early intervention in case of a complication, or to avoid from a potential damage.

Epistaxis was retrospectively evaluated in 35 dogs. Systemic disease was diagnosed in seven dogs and intranasal disease in 29. Nineteen dogs with intranasal disease had neoplasia. Dogs with neoplasia were older (mean 10.0 years) than dogs with nonneoplastic intranasal disease (mean 5.6 years). Signs persisting for >1 month occurred more often in dogs with intranasal than systemic disease. Unilateral epistaxis did not distinguish intranasal from systemic disease. Only dogs with intranasal disease had facial deformity, decreased airflow, or regional sub-mandibular lymphadenopathy. Dogs with systemic disease had a lower packed cell volume (mean 31.8%) than dogs with intranasal disease (mean 42.7%).

Objective: Topical oxygen devices are Food and Drug Administration (FDA) cleared for the following indications for use of various etiologies: skin ulcerations due to diabetes, venous stasis, postsurgical infections and gangrenous lesions, decubitus ulcers; amputations/infected stumps; skin grafts; burns; and frostbite. The goal of this study was to understand the impact of topical oxygen therapy (TOT) on patient outcomes, including amputation and healing rates. Approach: This retrospective chart review included records collected between January 1, 2007, and July 18, 2016, from male and female patients ranging in age from 4 years to 105 years. All wounds were at least 1 cm 2 and were treated with at least one separate modality before treatment with TOT and then treated with TOT for a minimum of 2 weeks in compliance with the FDA-approved indications. All records were from wounds that were no longer being treated with TOT. Results: In this study, TOT was associated with an overall rate of 59.4% for a reduction in chronic wound size, while 41.6% of wounds had no healing. The overall amputation rate was 2.4% for wounds in this study. Innovation: To our knowledge, this retrospective chart review represents one of the largest data sets (4,127 total wounds) collected over one of the longest time periods (9.5 years) to evaluate patient outcomes following TOT. Conclusion: This study revealed healing and amputation rates similar to those reported in controlled clinical studies using TOT to treat chronic wounds.

Background. Colorectal cancer (CRC) is a growing public health concern with increasing rates in countries with previously known low incidence. This study determined pattern and distribution of CRC in Tanzania and identified hot spots in case distribution. Methods. A retrospective chart audit reviewed hospital registers and patient files from two national institutions. Descriptive statistics, Chi square (χ 2) tests, and regression analyses were employed and augmented by data visualization to display risk variable differences. Results. CRC cases increased sixfold in the last decade in Tanzania. There was a 1.5% decrease in incidences levels of rectal cancer and 2% increase for colon cancer every year from 2005 to 2015. Nearly half of patients listed Dar es Salaam as their primary residence. CRC was equally distributed between males (50.06%) and females (49.94%), although gender likelihood of diagnosis type (i.e., rectal or colon) was significantly different (P = 0.027). More than 60% of patients were between 40 and 69 years. Conclusions. Age (P = 0.0183) and time (P = 0.004) but not gender (P = 0.0864) were significantly associated with rectal cancer in a retrospective study in Tanzania. Gender (P = 0.0405), age (P = 0.0015), and time (P = 0.0075) were all significantly associated with colon cancer in this study. This retrospective study found that colon cancer is more prevalent among males at a relatively younger age than rectal cancer. Further, our study showed that although more patients were diagnosed with rectal cancer, the trend has shown that colon cancer is increasing at a faster rate. PMID:27965709

Atomoxetine is a non-stimulant drug indicated for the treatment of attention-deficit/hyperactivity disorder in children aged ≥6 years, adolescents, and adults. In this retrospective cohort study, the incidence and risk of dystonia in children and adolescents treated with atomoxetine was compared to a propensity score-matched cohort of stimulant users. Data between 1 January 2006 and 31 December 2014 from patients aged 6-17 years in the Truven Health Analytics MarketScan database were used to generate two cohorts of patients: (1) atomoxetine users and (2) stimulant (methylphenidates or amphetamines) users. A Cox proportional hazards regression model was used to compare incidence of dystonia across propensity score-matched cohorts. Of the 70,657 atomoxetine users, 70,655 users were propensity score-matched to a stimulant user. In the atomoxetine- and stimulant-treated cohorts, the crude incidence rates of dystonia were 54.9 (95% CI: 27.1-82.7) and 77.9 (95% CI: 49.1-106.8) per 100,000 person-years, respectively. The hazard ratio for occurrence of dystonia with atomoxetine use relative to stimulant use was 0.68 (95% CI: 0.36 - 1.28; P = 0.23). In this large retrospective cohort study, there was no significant difference in incidence or risk of dystonia among patients treated with atomoxetine compared to stimulants.

Both prospective informant-reports and retrospective self-reports may be used to measure childhood maltreatment, though both methods entail potential limitations such as underestimation and memory biases. The validity and utility of standard measures of childhood maltreatment requires clarification in order to inform the design of future studies investigating the mental health consequences of maltreatment. The present study assessed agreement between prospective informant-reports and retrospective self-reports of childhood maltreatment, as well as the comparative utility of both reports for predicting a range of psychiatric problems at age 18. Data were obtained from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally-representative birth cohort of 2232 children followed to 18 years of age (with 93% retention). Childhood maltreatment was assessed in two ways: (i) prospective informant-reports from caregivers, researchers, and clinicians when children were aged 5, 7, 10 and 12; and (ii) retrospective self-reports of maltreatment experiences occurring up to age 12, obtained at age 18 using the Childhood Trauma Questionnaire. Participants were privately interviewed at age 18 concerning several psychiatric problems including depression, anxiety, self-injury, alcohol/cannabis dependence, and conduct disorder. There was only slight to fair agreement between prospective and retrospective reports of childhood maltreatment (all Kappa's ≤ 0.31). Both prospective and retrospective reports of maltreatment were associated with age-18 psychiatric problems, though the strongest associations were found when maltreatment was retrospectively self-reported. These findings indicate that prospective and retrospective reports of childhood maltreatment capture largely non-overlapping groups of individuals. Young adults who recall being maltreated have a particularly elevated risk for psychopathology. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

We report a retrospective study of 47 consecutive patients with uterine sarcoma treated at the Churchill Hospital in Oxford between 1990-1998. The mainstay of treatment was surgery with adjuvant chemotherapy and radiotherapy reserved for selected patients with early stage disease. Overall 1 and 2 year survival was 49% and 30% respectively compared with 73% and 55% in the group who received adjuvant chemotherapy/radiotherapy. Median survival was 11 months for the group as a whole compared to 32.9 months in the adjuvant therapy group. This is a retrospective review with small numbers and considerable selection bias, however, given the poor survival of patients with this disease, adjuvant treatment should be considered in future trials of patients with uterine sarcoma.

Numerous studies have reported a decline in stroke-related mortality in developed countries. To assess trends in one-year mortality following a stroke diagnosis in Saudi Arabia. Retrospective longitudinal cohort study. Single tertiary care center from 2010 through 2014. All patients admitted with a primary admitting diagnosis of stroke. Demographic data (age, gender, nationality), risk factor profile, stroke subtypes, in-hospital complications and mortality data as well as cause of death were collected for all patients. A multivariable logistic regression model was used to assess factors associated with one-year mortality following a stroke admission. One-year mortality. In 548 patients with a mean age of 62.9 years (SD 16.9), the most frequent vascular risk factors were hypertension (90.6%), diabetes (65.5%), and hyperlipidemia (27.2%). Hemorrhagic stroke was diagnosed in 9.9%. The overall mortality risk was 26.9%. Non-Saudis had a significantly higher one-year mortality risk compared with Saudis (25% vs. 16.8%, respectively; P=.025). The most frequently reported causes of mortality were neurological and related to the underlying stroke (32%), sepsis (30%), and cardiac or other organ dysfunction-related (each 9%) in addition to other etiologies (collectively 9.5%) such as pulmonary embolism or an underlying malignancy. Significant predictors in the multivariate model were age (P < .0001), non-Saudi nationality (OR 1.8, CI 95 1.1 to 2.9; P=.019), and hospital length of stay (OR 1.01, CI 95 1 to 1.004; P=.001). We observed no decline in stroke mortality in our center over the 5-year span. The establishment of stroke systems of care, use of thrombolytic agents, and opening of a stroke unit should play an important role in a decline in stroke mortality. Retrospective single center study. Mortality data were available only for patients who died in our hospital.

To investigate the prevalence of oral lichen planus in patients younger than 18 years, referred to a dermatology centre in Iran during 2002-2014. Lichen planus is a chronic inflammatory, immune-mediated disease that could affect the oral mucosa and is a pre-cancerous condition. The disease usually develops in middle age with female predominance and is rare in children. In this retrospective study, cases with definitive histopathologic diagnosis of lichen planus, over a 12-year period from 2002 to 2014 from a dermatologic hospital archive were evaluated. The prevalence of both cutaneous and oral lichen planus, the male:female ratio and site of involvement were calculated using SPSS version 21. Thirty-six of 564 patients younger than 18 years old diagnosed with lichen planus. Two females (0.4%) had oral lichen planus. One patient had erosive, and one had bullous, oral lichen planus. Oral lichen planus had a very low frequency in Iranian population younger than 18 years old, identifying these patients is recommended for long-term follow-up.

To determine the pattern of occurrence of mandibular fractures in the pediatric population in Portugal. This retrospective study reviews the records of patients 18 years of age or younger from the 10-year period 1993 to 2002. Age, gender, anatomic site, cause of the accident, weekly and monthly variation, location and type of fractures, presence and location of associated injuries, treatment methods, and complications were reviewed. During this 10-year period, 521 patients with 681 mandibular fractures were treated. Motor-vehicle accident (MVA) was the most common (53.9% patients) cause of fracture. Almost half of the patients (48.8%) were in the oldest age group (16 to 18 years old). The condyle of the mandible was involved in 31.0% of the fractures. Maxillomandibular (MMF) fixation was used in 534 (78.4%) fractures. Overall mortality in this series was 0.6% (3 patients); mortality was caused by multiple traumas, mainly head trauma. There is a need to reinforce legislation aimed to prevent MVA and the total enforcement of existing laws to reduce maxillofacial injuries among children and adolescents.

The aim of this study was to assess change in the number of adolescent females prescribed hormonal contraception in primary care following the publication in the United Kingdom of the Social Exclusion Unit report on Teenage Pregnancy. We conducted a retrospective observational study of 320 primary care practices in Scotland. Hormonal contraceptive prescribing to girls aged <16 years and those aged 16-19 years was assessed for April 1 to March 31 for the study years 2000-2001 to 2005-2006 from Scottish primary care practice data. Between 2000-2001 and 2005-2006, the proportion of girls aged <16 years and those 16-19 years who were prescribed hormonal contraception by their primary care physicians increased by 82% (p < .001) and 53% (p < .001) respectively. The increase became significant from age 12 years for the combined oral contraceptive, 14 years for the progestogen-only pill, and 15 years for depot progestogens. By 2005-2006, 2.9% of girls aged <16 years and 40.5% of those aged 16-19 years were prescribed some form of hormonal contraception by their primary care physicians. The small number of girls aged <12 years who were prescribed hormonal contraception remained constant over the study period. Since the publication in the United Kingdom of the Social Exclusion Unit Report on Teenage Pregnancy, there has been a significant increase in the number of female adolescents aged > or =12 years prescribed hormonal contraception by their primary care physicians. However the number of individuals prescribed hormonal contraception still remains relatively low in comparison to the reported levels of sexual activity among adolescents in the United Kingdom.

To describe the design and baseline characteristics of patients enrolled into 2 natural history studies of Stargardt disease (STGD1). Multicenter retrospective and prospective cohort studies. Three hundred sixty-five unique patients aged 6 years and older at baseline harboring disease-causing variants in the ABCA4 gene and with specified ocular lesions were enrolled from 9 centers in the United States and Europe. In the retrospective study, patients contributed medical record data from at least 2 and up to 4 visits for at least 1 examination modality: fundus autofluorescence (FAF), spectral-domain (SD) optical coherence tomography (SD OCT), and/or microperimetry (MP). The total observational period was at least 2 years and up to 5 years between single visits. Demographic and visual acuity (VA) data also were obtained. In the prospective study, eligible patients were examined at baseline using a standard protocol, with 6-month follow-up visits planned for a 2-year period for serial Early Treatment Diabetic Retinopathy Study (ETDRS) best-corrected VA, SD OCT, FAF, and MP. Design and rationale of a multicenter study to determine the progression of STGD1 in 2 large retrospective and prospective international cohorts. Detailed baseline characteristics of both cohorts are presented, including demographics, and structural and functional retinal metrics. Into the retrospective study, 251 patients (458 eyes) were enrolled; mean follow-up ± standard deviation was 3.9±1.6 years. At baseline, 36% had no or mild VA loss, and 47% of the study eyes had areas of definitely decreased autofluorescence (DDAF) with an average lesion area of 2.5±2.9 mm(2) (range, 0.02-16.03 mm(2)). Two hundred fifty-nine patients (489 eyes) were enrolled in the prospective study. At baseline, 20% had no or mild VA loss, and 64% had areas of DDAF with an average lesion area of 4.0±4.4 mm(2) (range, 0.03-24.24 mm(2)). The mean retinal sensitivity with MP was 10.8±5.0 dB. The ProgStar cohorts have baseline characteristics that encompass a wide range of disease severity and are expected to provide valuable data on progression based on serial quantitative measurements derived from multiple methods, which will be critical to the design of planned clinical trials.

Our aim was to summarise the clinical characteristics and presentation of ameloblastomas in eastern Nigeria. We organised a retrospective study of 240 patients who presented with ameloblastomas to the Oral and Maxillofacial Surgery units of five specialist hospitals in the eastern states of Nigeria over an eight-year period (2004-2011). We analysed the casenotes, and categorised the cases by site of tumour, age, sex, and time of presentation. There were 117 men (49%) (mean (SD) age 43 (6.2) years) and 123 women (51%) (mean (SD) age 32 (4.7) years), a male:female ratio of 1:1.1. The largest age group was 20-39 years (n=102, 43%), and the most common site was the anterior mandible (n=140, 58%). Most of the patients presented late. Our results show that the most common site of ameloblastomas in Eastern Nigeria is the anterior mandible and that women are affected more than men, which is at variance with the results of most other studies.

The use of hyperinsulin therapy (HIT) in severe calcium channel antagonist (CCA) poisoning has become a more common therapy within the last decade. The objective of this study is to report 7 years of experience recommending HIT. This was a retrospective chart review utilizing our regional poison center (RPC) data from January 1, 2002, through December 31, 2008. All cases of CCA poisoning receiving HIT were searched. Endpoints included the number of CCA cases utilizing HIT, insulin dose, time of initiation of HIT, patient outcome, adverse events, age, glucose concentration, and lowest systolic blood pressure recorded. Forty-six cases of CCA poisoning were managed with HIT over 7 years. All the patients received standard antidotal therapy (= intravenous fluids, calcium salts, glucagon, and pressors). HIT administration followed our RPC recommendation 23 times (50%), and no hypoglycemic events occurred. Means (age, highest glucose measured, and lowest systolic blood pressure measured) were 51 years, 282 mg/dL, and 74 mm Hg, respectively. Our RPC recommendations for HIT were followed 50% of the time over the last 7 years. In light of the lack of hypoglycemia associated with HIT in our study population, we recommend HIT as an early and safe antidote in significant CCA poisoning.

We assessed the effectiveness of South Africa's Firearm Control Act (FCA), passed in 2000, on firearm homicide rates compared with rates of nonfirearm homicide across 5 South African cities from 2001 to 2005. We conducted a retrospective population-based study of 37 067 firearm and nonfirearm homicide cases. Generalized linear models helped estimate and compare time trends of firearm and nonfirearm homicides, adjusting for age, sex, race, day of week, city, year of death, and population size. There was a statistically significant decreasing trend regarding firearm homicides from 2001, with an adjusted year-on-year homicide rate ratio of 0.864 (95% confidence interval [CI] = 0.848, 0.880), representing a decrease of 13.6% per annum. The year-on-year decrease in nonfirearm homicide rates was also significant, but considerably lower at 0.976 (95% CI = 0.954, 0.997). Results suggest that 4585 (95% CI = 4427, 4723) lives were saved across 5 cities from 2001 to 2005 because of the FCA. Strength, timing and consistent decline suggest stricter gun control mediated by the FCA accounted for a significant decrease in homicide overall, and firearm homicide in particular, during the study period.

To determine causes of death for Peace Corps Volunteers (PCV) between 1984 and 2003 and compare them with prior Volunteer death rates and with US death rates. We conducted a retrospective cohort study of all PCV between 1984 and 2003 and compared them to published data for prior years and against US death rates. Of the 66 deaths in our study period, the major causes were unintentional injury, homicide, medical illness, and suicide. Comparisons to US mortality data controlled for age, marital status, and educational attainment found equal or lower death rates among Volunteers. When compared to previous study results from 1961 to 1983, the total number of deaths, as well as the death rate per Volunteer-year, decreased. Deaths from unintentional injury, suicide, and medical illness decreased in number and rate; only homicides increased in number during our study period, but this increase did not reach statistical significance. PCV are exposed to unique risks, but these risks have become significantly less fatal over the past 20 years when compared to prior Peace Corps data and matched US population data.

Purpose: To present, analyze, and discuss results of a nationwide, multicenter, retrospective study on high-dose-rate brachytherapy (HDR-BT) as monotherapy for low-, intermediate-, and high-risk prostate cancer. Methods and Materials: From 1995 through 2013, 524 patients, 73 (14%) with low-risk, 207 (40%) with intermediate-risk, and 244 (47%) with high-risk prostate cancer, were treated with HDR-BT as monotherapy at 5 institutions in Japan. Dose fractionations were 27 Gy/2 fractions for 69 patients (13%), 45.5 Gy/7 fractions for 168 (32%), 49 Gy/7 fractions for 149 (28%), 54 Gy/9 fractions for 130 (25%), and others for 8 (2%). Of these patients, 156 (30%) did not receive androgen deprivationmore » therapy, and 202 patients (39%) did receive androgen deprivation therapy <1 year, 112 (21%) for 1-3 years, and 54 (10%) for >3 years. Median follow-up time was 5.9 years (range, 0.4-18.1 years), with a minimum of 2 years for surviving patients. Results: After 5 years, respective actuarial rates of no biochemical evidence of disease, overall survival, cause-specific survival, and metastasis-free survival for all patients were 92%, 97%, 99%, and 94%. For low/intermediate/high-risk patients, the 5-year no biochemical evidence of disease rates were 95%/94%/89%, the 5-year overall survival rates were 98%/98%/94%, the 5-year cause-specific survival rates were 98%/100%/98%, and the 5-year metastasis-free survival rates were 98%/95%/90%, respectively. The cumulative incidence of late grade 2 to 3 genitourinary toxicity at 5 years was 19%, and that of late grade 3 was 1%. The corresponding incidences of gastrointestinal toxicity were 3% and 0% (0.2%). No grade 4 or 5 of either type of toxicity was detected. Conclusions: The findings of this nationwide, multicenter, retrospective study demonstrate that HDR-BT as monotherapy was safe and effective for all patients with low-, intermediate-, and high-risk prostate cancer.« less

Seizures are a hallmark manifestation of tuberous sclerosis complex, yet data characterizing resource utilization are lacking. This retrospective chart review was performed to assess the economic burden of tuberous sclerosis complex with neurologic manifestations. Demographic and resource utilization data were collected for 95 patients for up to 5 years after tuberous sclerosis complex diagnosis. Mean age at diagnosis was 3.1 years, with complex partial and infantile spasms as the most common seizure types. In the first 5 years post-diagnosis, 83.2% required hospitalization, 30.5% underwent surgery, and the majority of patients (90.5%) underwent ≥3 testing procedures. In 79 patients with a full 5 years of data, hospitalizations, intensive care unit stays, diagnostic testing, and rehabilitation services decreased over the 5-year period. Resource utilization is cost-intensive in children with tuberous sclerosis complex and associated seizures during the first few years following diagnosis. Improving seizure control and reducing health care costs in this population remain unmet needs.

Objectives To investigate the association between the trends of CT utilisation in an emergency department (ED) and changes in clinical imaging practice and patients' disposition. Setting A hospital-based retrospective observational study of a public 1520-bed referral medical centre in Taiwan. Participants Adult ED visits (aged ≥18 years) during 2009–2013, with or without receiving CT, were enrolled as the study participants. Main outcome measures For all enrolled ED visits, we retrospectively analysed: (1) demographic characteristics, (2) triage categories, (3) whether CT was performed and the type of CT scan, (4) further ED disposition, (5) ED cost and (6) ED length of stay. Results In all, 269 239 adult ED visits (148 613 male patients and 120 626 female patients) were collected during the 5-year study period, comprising 38 609 CT scans. CT utilisation increased from 11.10% in 2009 to 17.70% in 2013 (trend test, p<0.001). Four in 5 types of CT scan (head, chest, abdomen and miscellaneous) were increasingly utilised during the study period. Also, CT was increasingly ordered annually in all age groups. Although ED CT utilisation rates increased markedly, the annual ED visits did not actually increase. Moreover, the subsequent admission rate, after receiving ED CT, declined (59.9% in 2009 to 48.2% in 2013). Conclusions ED CT utilisation rates increased significantly during 2009–2013. Emergency physicians may be using CT for non-emergent studies in the ED. Further investigation is needed to determine whether increasing CT utilisation is efficient and cost-effective. PMID:27279477

Little is known about how physical activity patterns during childhood and adolescence are associated with risk of subsequent depression. We examined prospective and retrospective associations between leisure physical activity patterns from childhood to adulthood and risk of clinical depression in young adulthood. Participants (759 males, 871 females) in a national survey, aged 9-15 years, were re-interviewed approximately 20 years later. Leisure physical activity was self-reported at baseline (1985) and follow-up (2004-2006). To bridge the interval between the two time-points, historical leisure activity from age 15 years to adulthood was self-reported retrospectively at follow-up. Physical activity was categorized into groups that, from a public health perspective, compared patterns that were least beneficial (persistently inactive) with those increasingly beneficial (decreasing, increasing and persistently active). Depression (major depressive or dysthymic disorder) was assessed using the Composite International Diagnostic Interview. Compared with those persistently inactive, males who were increasingly and persistently active had a 69 and 65 % reduced risk of depression in adulthood, respectively (all p < 0.05). In retrospective analyses, females who were persistently active had a 51 % reduced risk of depression in adulthood (p = 0.01). Similar but non-significant trends were observed for leisure physical activity in females and historical leisure activity in males. Results excluded those with childhood onset of depression and were adjusted for various sociodemographic and health covariates. Findings from both prospective and retrospective analyses indicate a beneficial effect of habitual discretionary physical activity since childhood on risk of depression in young adulthood.

Interstitial cystitis/bladder pain syndrome (IC/BPS) has several well-known comorbid psychiatric manifestations, including insomnia, anxiety, and depression. We hypothesized that somatoform disorder, which is a psychosomatic disease, can be used as a sensitive psychiatric phenotype of IC/BPS. We investigated whether somatoform disorder increases the risk of IC/BPS.A nested case-control study and a retrospective cohort study were followed up over a 12-year period (2002-2013) in the Taiwan Health Insurance Reimbursement Database. In the nested case-control study, 1612 patients with IC/BPS were matched in a 1:2 ratio to 3224 controls based on propensity scores. The odds ratio for somatoform disorder was calculated using conditional logistic regression analysis. In the retrospective cohort study, 1436 patients with somatoform disorder were matched in a 1:2 ratio to 2872 patients with nonsomatoform disorder based on propensity scores. Cox regression analysis was used to estimate the hazard ratio associated with the development of IC/BPS in patients with somatoform disorder, and the cumulative survival probability was tested using the Kaplan-Meier analysis.We found that the odds ratio for somatoform disorder was 2.46 (95% confidence interval [CI], 1.05-5.76). Although the average time until IC/BPS development in the control subjects was 11.5 ± 1.3 years, this interval was shorter in patients with somatoform disorder (6.3 ± 3.6 years). The hazard ratio for developing IC/BPS was 2.50 (95% CI 1.23-5.58); the adjusted hazard ratio was 2.26 (95% CI 1.002-5.007). The patients and controls also differed significantly in their cumulative survival probability for IC/BPS (log rank P < .05).Evidence from the nested case-control study and retrospective cohort study consistently indicated that somatoform disorder increases the risk for IC/BPS. Our study suggests that somatoform disorder can be used as a sensitive psychiatric phenotype to predict IC/BPS. Any past history of somatoform disorder should be documented while examining patients with IC/BPS.

The aim of the present study was to retrospectively evaluate women who were admitted to Hiroshima University Hospital, Department of Psychiatry and Neurosciences, from 1979 to 2008. The women were classified as 'depressed women' (n = 159; mean age, 52.3 +/- 5.7 years) or 'non-depressed women' (n = 182; mean age, 51.5 +/- 4.5 years). A total of 14.5% of the depressed women and 3.3% of the non-depressed women had a hysterectomy and/or oophorectomy; this difference was statistically significant (P = 0.0003). This is consistent with previous reported information as well as clinical experience that depressed women had a higher incidence of hysterectomy and/or oophorectomy.

Purpose: To retrospectively analyze and assess the outcomes and prognostic factors in a large number of patients with atypical and malignant meningiomas. Methods and Materials: Ten academic medical centers participating in this Rare Cancer Network contributed 119 cases of patients with atypical or malignant meningiomas treated with external beam radiotherapy (EBRT) after surgery or for recurrence. Eligibility criteria were histologically proven atypical or anaplastic (malignant) meningioma (World Health Organization Grade 2 and 3) treated with fractionated EBRT after initial resection or for recurrence, and age >18 years. Sex ratio (male/female) was 1.3, and mean ({+-}SD) age was 57.6 {+-} 12more » years. Surgery was macroscopically complete (Simpson Grades 1-3) in 71% of patients; histology was atypical and malignant in 69% and 31%, respectively. Mean dose of EBRT was 54.6 {+-} 5.1 Gy (range, 40-66 Gy). Median follow-up was 4.1 years. Results: The 5- and 10-year actuarial overall survival rates were 65% and 51%, respectively, and were significantly influenced by age >60 years (p = 0.005), Karnofsky performance status (KPS) (p = 0.01), and high mitotic rate (p = 0.047) on univariate analysis. On multivariate analysis age >60 years (p = 0.001) and high mitotic rate (p = 0.02) remained significant adverse prognostic factors. The 5- and 10-year disease-free survival rates were 58% and 48%, respectively, and were significantly influenced by KPS (p 0.04) and high mitotic rate (p = 0.003) on univariate analysis. On multivariate analysis only high mitotic rate (p = 0.003) remained a significant prognostic factor. Conclusions: In this multicenter retrospective study, age, KPS, and mitotic rate influenced outcome. Multicenter prospective studies are necessary to clarify the management and prognostic factors of such a rare disease.« less

Rotavirus (RV) vaccination was introduced into the UK vaccination schedule in July 2013. This retrospective observational study assessed, in a UK setting, the impact of the vaccination programme on the number of RV gastroenteritis (RVGE) admissions, the complications of RVGE in hospitalised children, and the impact on hospital-acquired RVGE. Over a 3 year period, 1-year before and 2 years after the introduction of the vaccine, children under 13 years of age in Lothian region with RV+ve stool sample by PCR were identified, retrospectively, and admission data (length of stay, complications) and vaccination status analysed. Viral strain (vaccine/wild type) was typed using PCR-based methods in vaccinated children. Vaccination uptake in the first 2 years of the programme was 93-94%. In the 2 years following vaccine introduction, the annual number of confirmed RVGE admissions fell by 84.7% (95% CI 75.4 to 91.0), from 131 to 20, bed days reduced by 91.1% (86.9 to 94.1), from 325 to 29, and suspected hospital-acquired infections reduced by 95.7% (73.5-99.5), from 23 to 1. The reduction in admissions was seen across all age groups despite the vaccination only being administered to infants. Despite the reduction in incidence, complication rates in children admitted with RVGE remained unchanged across the three study years. A frequent incidental finding was RV vaccine strain in the stools of vaccinated children, up to 43 days after last immunisation. There has been no concurrent increase in rate of intussusception in the region. These results provide encouraging initial evidence of the public health benefit, including to the unimmunised population, of the RV vaccination programme in the UK.

While most previous surveys on the clinico-epidemiological features of autoimmune bullous diseases (AIBDs) have predominantly focused on a single disease entity or just one disease group, there have been only few studies examining the incidence of various AIBDs. In the present study, we set out to determine the spectrum of AIBDs, to estimate the incidence of the most common AIBDs, and to examine their temporal trends in Central Serbia over a period of 20 years. We retrospectively recruited 1,161 new AIBD cases diagnosed in Central Serbia during the period from January 1991 to December 2010. The diagnosis was based on strict clinical, histological, and immunohistological evaluation. The incidence rates were: 4.35 per million population/year (pmp/year) for pemphigus, 4.47 pmp/year for pemphigoid, 1.42 pmp/year for dermatitis herpetiformis (DH), 0.25 pmp/year for linear IgA disease, and 0.08 pmp/year for epidermolysis bullosa acquisita. In the period observed, age-adjusted incidence rates significantly increased for pemphigus and particularly for pemphigoid, whereas they decreased, albeit not significantly, for DH. For the first time, our study evaluates the incidence rates of the entire spectrum of AIBDs in Serbia, and examines their temporal trends over a 20-year period. To the best of our knowledge, our finding of similar incidence rates for pemphigus and pemphigoid has previously not been reported. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

Fractures of facial bones in children are relatively uncommon although both children and adults are subjected to similar types of injuries. This study aims to evaluate the epidemiology of facial bone fractures among children under 14 years, their management and outcome. This retrospective study included maxillofacial injuries treated in 112 children under 14 years admitted due to maxillofacial injuries during the period from 2001 to 2011. Of them ten (8.93 %) were below 5 years, 44 (39.29 %) between 6 and 10 years and 58 (51.78 %) between 11 and 14 years of age. Male to female ratio was 1.8:1. Fall from a height was the most common etiology. The most common jaw involved in the fracture was the mandible. Conservative management was done in 83.04 % of cases and open reduction and internal fixation was performed in 16.96 % of cases. Five (4.46 %) cases accounted for post-operative wound infection. Fracture of the mandible is the most common maxillofacial injury in children, most often caused by fall from a height. The osteogenic potential of the mandible in children leads to conservative management of these fractures. Opportunities for prevention of maxillofacial trauma should be taken into consideration by parents and care takers.

The retrospective analysis of bibliographical trends for nine biomedical engineering journals from 1999 to 2007.

PubMed

2009-07-01

For academic research outcomes, there is an increasing emphasis on the bibliometric scorings like the journal impact factor (JIF) when assessment of the quality of research is required. Currently, no known study has been conducted to explore the bibliographical trends of the biomedical engineering journals indexed by the annual Journal Citation Reports of the Thomson Scientific. In this study, the trends of nine reputable journals were selected and analyzed over a 9-year period (year 1999 to year 2007). The results show that the JIF rose exponentially for some journals (up to 597.0%) while for others, it shrank (down to -19.5%). A similar trend is observed for the citations trend over the same period and there was a significant increase in the number of citable articles published (> or =23.6%) in all the selected journals using year 1999 as the base year. However, journals which published significant more non-research articles (> or =10%) saw favorable subsequent effects on their citations. It is postulated that the changes in bibliographical trends can be classified as editorial and non-editorial influences. The retrospective impacts of these influences on the nine selected journals over the 9-year period were also discussed in this study.

The overall median lifespan of domestic dogs has been estimated to 9-12 years, but little is known about risk factors for mortality in aged and a priori healthy dogs. The objective of this retrospective cohort study was to determine which characteristics are associated with mortality in aged and a priori healthy guide dogs, in a retrospective cohort study of 116 guide dogs followed from a systematic geriatric examination at the age of 8-10 years old. A geriatric grid collected the clinical data and usual biological parameters were measured at the time of examination. Univariate (Kaplan-Meier estimates) and multivariable (Cox proportional hazard model) survival analyses were used to assess the associations with time to all-cause death. The majority of dogs were Golden Retrievers (n=48) and Labrador Retrievers (n=27). Median age at geriatric examination was 8.9 years. A total of 76 dogs died during follow-up, leading to a median survival time from geriatric examination of 4.4 years. After adjustment for demographic and biological variables, an increased alanine amionotransferase level (adjusted Hazard Ratio (adjusted HR), 6.2; 95% confidence interval [95%CI], 2.0-19.0; P<0.01), presenting skin nodules (adjusted HR, 1.9; 95% CI, 1.0-3.4; P=0.04), and not being a Labrador Retriever (adjusted HR, 3.3; 95%CI, 1.4-10; P<0.01) were independently associated with a shorter time to death. This study documents independent associations of alanine aminotransferase level, skin nodules and breed with mortality in aged guide dogs. These results may be useful for preventive medical care when conducting a geriatric examination in working dogs. Copyright © 2016 Elsevier B.V. All rights reserved.

Prescription opioids (PO) addiction is increasing to an epidemic level. Few studies exist regarding its treatment. Although buprenorphine has been the mainstay so far, other treatment options might be considered, such as methadone. We conducted a retrospective assessment of all patients admitted to a psychiatry ward for PO detoxification using methadone between 2010 and 2013. The assessment and description was carried out during a 3-month follow-up period after their discharge. Although this is a retrospective chart review, our exploration included sociodemographic and treatment variables in addition to the abstinence rates for the whole sample. Eleven patients were included, mostly women (81.8%), with a median age of 50 years. The median duration of dependence was 8 years. Dependence on other substances and psychiatric comorbidities were high. Eight patients were monitored during three months. Of these, 7 (87.5%) were abstinent after that period. The results suggest that methadone deserves further exploration as a potentially efficacious treatment option for PO dependence.

This study aims to investigate whether previous AAS-use affects mental health, present sociodemographic data, sport activity and substance abuse in a retrospective 30-year follow-up study of former elite athletes. Swedish male-elite power sport athletes (n=683) on the top 10 national ranking lists during any of the years 1960-1979 in wrestling, Olympic lifting, powerlifting and the throwing events in track and field answered a questionnaire. At least 20% of the former athletes admitted previous AAS-use. They had more often sought professional expertise for mental problems and had used illicit drugs compared to those not having used AAS. The AAS-users also differed in former sport activity pattern compared to non AAS-users. It is clear that a relationship exists between use of AAS and mental-health problems. Further studies need to be done in order to clarify this relationship.

Assessment of dental caries predictors in 6-year-old school children - results from 5-year retrospective cohort study

PubMed Central

2012-01-01

Background This was a retrospective cohort study undertaken to assess the rate and pattern of dental caries development in 6-year-old school children followed-up for a period of 5 years, and to identify baseline risk factors that were associated with 5 years caries experience in Malaysian children. Methods This 5-years retrospective cohort study comprised primary school children initially aged 6 years in 2004. Caries experience of each child was recorded annually using World Health Organization criteria. The rates of dental caries were recorded in prevalence and incidence density of carious lesions from baseline to final examination. Risk assessment was done to assess relative risk for caries after 5 years in children with baseline caries status. Simple and multiple logistic regression analysis were performed to identify significant independent risk factors for caries. Results The sample consisted of 1830 school children. All components of DMFT showed significant differences between baseline and final examination. Filled teeth (FT) component of the DMFT showed the greatest increases. Results revealed the initial baseline caries level in permanent dentition was a strong predictor for future caries after 5 years (RR=3.78, 95% CI=3.48-4.10, P<0.001). Logistic regression analysis showed significant association between caries occurrence and residence (urban/rural) (OR=1.80, P<0.001). However, it was not significantly associated with gender and ethnicity. The incidence density of caries, affected persons (IDp) observed from baseline and after 5 years was 5.80 persons/100 person-year of observation. The rate of new caries-affected tooth (IDt) in the period from baseline and after 5-years was 0.76 teeth/100 teeth-year of observation. Conclusion The majority of 12-year-old school children (70%) were caries-free and most of the caries were concentrated in only a small proportion (30%) of them. We found that the presence of caries in permanent teeth at the age of 6 years was a strong predictor of future caries development in this population. The strong evidence of early permanent teeth caries at six years old to predict future caries incidence at 12-year-olds, which could be obtained at almost no cost, questions the need for and cost-effectiveness of expensive technology-based commercial caries predictions kits.

With two study protocols, one retrospective and the other prospective, we evaluated hypothalamo-hypophysial dysfunction (HHD) in paediatric patients treated for traumatic brain injury (TBI) in the neurosurgical or intensive care department at our hospital. The retrospective group comprised 22 patients who had experienced TBI 0.7-7.25 years before the study. The prospective group included 30 patients assessed at TBI (T0), 26 of 30 after 6 months (T6), and 20 of 26 after 12 months (T12). Auxological and hormonal basal parameters of hypothalamo-hypophysial function were evaluated at recall in the retrospective group, and at T0, T6 and T12 in the prospective group. Basal data and standard dynamic tests in selected patients revealed one with precocious puberty, one with total anterior hypopituitarism, one with central hypogonadism, and one with growth hormone (GH) deficiency in the retrospective group; three patients with cerebral salt-wasting syndrome, one with diabetes insipidus and seven with low T3 syndrome at T0 (all transient), one with hypocorticism at T6 confirmed at T12, and one with GH deficiency at T12 in the prospective group. The results of our study show that post-TBI HHD in our paediatric cohort is not uncommon. Of the 48 patients who underwent a complete evaluation (22 retrospective study patients and 26 prospective study patients evaluated at T6) five (10.4%) developed HHD 6 months or more after TBI. HHD was newly diagnosed in one previously normal patient from the prospective group at 12 months after TBI. GH deficiency was the most frequent disorder in our paediatric cohort.

Substance use disorders constitute a serious and persistent threat to military readiness and to the health and safety of military personnel and their families. Methamphetamine is among the most addictive and damaging of commonly abused drugs; this is of great concern for military health providers in Hawaii due to the unusually high prevalence in the local community. The effect of regional drug use on active duty subpopulations has not been previously studied. This study includes a 6-year retrospective sample of laboratory-confirmed methamphetamine-, cocaine-, and marijuana-positive drug tests among Army soldiers stationed in Hawaii and western and eastern continental U.S. installations. The findings suggest that active duty members are significantly affected by the local drug climate. However, current military drug policies also deter use as evidenced by low absolute drug-positive rates even in regions of high civilian prevalence.

Only few long-term data on ligament-balanced cruciate-retaining total knee arthroplasty (CR TKA) are currently available. Either a mobile- or fixed-bearing insert can be chosen, which showed good mid-term outcome and few complications and revisions. This multi-centre retrospective cross-sectional cohort study investigated the 12-year results of primary TKA using a balancing gap technique and compared survival and clinical outcome between fixed and mobile inserts. In this retrospective cross-sectional cohort study, 557 cases of three clinics (2 Swiss, 1 Dutch) operated between 1998 and 2003 with the first series of a TKA implanted with a balanced gap technique (433 (77.7%) fixed, 124 (22.3%) mobile (anterior-posterior gliding (7-9 mm) and rotational (15°) degrees of freedom) inserts) were included for survival analysis (Kaplan-Meier, by insert type). At the 12-year follow-up (FU) examination of 189 cases, range of motion, knee society score (KSS), numeric rating scale (NRS) for pain and satisfaction were determined and radiographs were evaluated by median tests, by insert type. Of 521 cases available for analysis, 28 (5.4%; 11 fixed, 17 mobile bearing) were revised. Mean cumulative survival after 12.4 years was 97.0% (95% CI 94.7-98.4) for fixed bearings and 85.4% (95% CI 77.5-90.7) after 12.2 years for mobile bearings, p < 0.0001. Patients' mean age at 11.0 years FU (n = 189) was 78.0 (range 54.5-97.3) years. Mean total KSS was 157.8 (24-200) points, and mean passive flexion was 114° (45-150); no clinical score differed significantly between fixed and mobile bearings. This study showed a superior survival for fixed bearing compared with mobile bearing in a CR TKA using a ligament-balanced technique after more than 12 years. Clinical outcomes are excellent to good after long-term follow-up, and similar for fixed and mobile bearing. Therapeutic studies-retrospective cohort study, Level III.

The "oldest old" are now the fastest growing section of most western populations, yet there are scarcely any data concerning even the common problem of falls amongst the very old. Prospective data collection is encouraged as the most reliable method for researching older people's falls, though in clinical practice guidelines advise taking a history of any recalled falls. This study set out to inform service planning by describing the epidemiology of falls in advanced old age using both retrospectively and prospectively collected falls data. Re-survey of over-90-year-olds in a longitudinal cohort study - cross-sectional interview and intensive 12-month follow-up. 90 women and 20 men participating in a population-based cohort (aged 91-105 years, in care-homes and community-dwelling) recruited from representative general practices in Cambridge, UKMeasurements: Prospective falls data were collected using fall calendars and telephone follow-up for one year after cross-sectional survey including fall history. 58% were reported to have fallen at least once in the previous year and 60% in the 1-year follow-up. The proportion reported to have fallen more than once was lower using retrospective recall of the past year than prospective reports gathered the following year (34% versus 45%), as were fall rates (1.6 and 2.8 falls/person-year respectively). Repeated falls in the past year were more highly predictive of falls during the following year - IRR 4.7, 95% CI 2.6-8.7 - than just one - IRR 3.6, 95% CI 2.0-6.3, using negative binomial regression. Only 1/5 reportedly did not fall during either the year before or after interview. Fall rates in this representative sample of over-90-year-olds are even higher than previous reports from octogenarians. Recalled falls last year, particularly repeated falls, strongly predicted falls during follow-up. Similar proportions of people who fell were reported by retrospective and prospective methods covering two consecutive years. Recall methods may underestimate numbers of repeated falls and the extent of recurrent falling. Professionals caring for people of advanced age can easily ask routinely whether someone has fallen at all, or more than once, in the past year to identify those at high risk of subsequent falls.

Tinea capitis is considered as a public health problem in Senegal. The aim of this study was to investigate trends in the incidence, the mycological and epidemiological aspects of tinea capitis diagnosed at Le Dantec Hospital in Dakar. Our work is a retrospective study concerning all scalp samples taken by the parasitology laboratory, over a 6-year period (2008-2013). A total of 1640 specimens were examined. Of these, 566 were positive with direct examination and after culture. We noted the reduction of patients and of the incidence of tineas during 6 years with variations of 147 (46.82%) to 37 (22.02%). The average incidence of the tineas during six years was 34.51%. Patients' age varied between 1 to 83 years with a mean of 27.33 years. Prevalence varied between age groups, with 10.61 % in adults between 20 to 29 years, 7.19% in children between 0 to 9 years, 6.04% between 10 to 19 years, and 5.91% in adults between 30 to 39 years. Women were more infected 469 (82.9%) than men 97 (17.1%). The main dermatophytes isolated were: T. soudanense in 318 cases (56.18%), T. rubrum in 104 cases (18.37%), M. langeronii in 72 cases (12.72%), M. canis in 36 cases (6.36%), and T. mentagrophytes in 26 cases (4.60%). Our study showed a decrease in the annual incidence of tinea capitis over the study period with an evident increase in trichophytic tinea. This study showed that tinea is endemic in Senegal mainly among women between 20 and 29 years. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

2018-06-01

There is an increasing trend to investigate plantar heel pain with magnetic resonance imaging (MRI) scan though plantar fasciitis is the most common cause. The purpose of our study was to evaluate the role of MRI in patients presenting with plantar heel pain. Case notes and MRI scans of 141 patients with a clinical diagnosis of plantar fasciitis were reviewed retrospectively. There were 98 females and 43 males patients. Fourteen patients had bilateral symptoms. Average age for male patients was 51 years (range = 26-78 years), and for female patients the average age was 52 years (range = 29-76 years). A total of 121 feet had MRI features suggestive of plantar fasciitis. MRI was normal in 32 feet. There was one case of stress fracture of calcaneus and another of a heel fibroma diagnosed on MRI scan. In our study, MRI scan was normal in 20.7% of the cases; 1.3% had a diagnosis other than plantar fasciitis but no sinister pathology. We therefore conclude that MRI scan is not routinely indicated and key is careful clinical assessment. Therapeutic, Level IV: Retrospective, Case series.

2017-02-01

A question arose in our practice of whether all cysts considered sebaceous should be sent for pathologic evaluation. To address this controversial topic, we performed a retrospective study of our single institution's histopathology database. A natural language search of the CoPath database across the institution was undertaken using the diagnosis of sebaceous cyst, epidermal cyst, epidermoid cyst, epithelial cyst, infundibular cyst, pilar cyst, trichilemmal cyst, and steatocystoma. A surgical pathologic review of all specimens with one of these preexcision diagnoses was included in the 15-year retrospective study of 1998 to 2013. All slides were confirmed to have undergone histopathologic review, and the preexcision diagnoses were compared with the postexcision diagnoses. Chart review was undertaken in instances of a diagnosis of malignancy. A total of 13,746 samples were identified. Forty-eight specimens had histopathologic diagnosis of malignancy, for an incidence of 0.3% and with the most common malignancy being squamous cell carcinoma. Chart review showed that for all cases, the surgeons reported uncertainty with regard to the diagnosis because of history or physical characteristics, or both. In addition, a comprehensive literature review showed results consistent with our data and illustrated 19 cases during the past 10 years in which most of the findings were squamous cell carcinoma. We propose the recommendation that routine pathologic evaluation of sebaceous cysts is necessary only when clinical suspicion exists.

1989-04-01

A sample of 99 resin-bonded prostheses placed over a 10-year period were examined by four clinicians using a standardized criteria sheet. Areas examined included hard tissues, periodontium, retainer and pontic design, retention, the effect of occlusion on framework design and retention rate, and bonding media. The data from 7- and 10-year retrospective studies were compared for meaningful trends. Results showed (1) caries on retainer teeth was 3%, (2) gingival index of the retainer teeth was less than the gingival index of the rest of the mouth (0.7 +/- 0.5 versus 0.9 +/- 0.6), (3) the respective mean probing depths of retainer teeth of 34 patients in the 7- and 10-year studies were 2.2 +/- 0.4 mm and 1.9 +/- 0.7 mm, (4) the debond rate of all the prostheses from all causes was 31%, (5) the debond rate comparing etched metal and perforated retainers from all causes was 32% and 31% [corrected], respectively, and (6) 83% liked the prosthesis; 17% were noncommittal. The authors concluded that the resin-bonded prosthesis may be considered a permanent restoration and a valuable asset in the clinician's armamentarium.

Complications of the retromandibular transparotid approach for low condylar neck and subcondylar fractures: a retrospective study

PubMed Central

2018-01-01

Objectives The goal of this study was to evaluate the rates of complications, morbidity, and safety with the transparotid approach. Materials and Methods A retrospective study was conducted and consisted of 53 surgically treated patients in the past five years for low condylar neck and subcondylar fractures. Only patients with malocclusion and who underwent open reduction with internal fixation with the retromandibular transparotid approach were included. The examined parameters were postoperative suboptimal occlusion, deflection, saliva fistula, and facial nerve weakness. Results Fifty-three patients had an open reduction with internal fixation on 55 sides (41 males, 77.4%; mean age, 42 years [range, 18–72 years]). Four patients (7.5%) experienced transient facial nerve weakness of the marginal mandibular branch, but none was permanent. Four patients had a salivary fistula, and 5 patients showed postoperative malocclusion, where one needed repeat surgery after one year. One patient showed long-term deflection. No other complications were observed. Conclusion The retromandibular transparotid approach is a safe procedure for open reduction and internal fixation of low condylar neck and subcondylar fractures, and it has minimal complications.

The facial region is a commonly fractured site, but the etiology varies widely by country and geographic region. To date, there are no population-based studies of facial fractures in Taiwan. We conducted a retrospective study of patients diagnosed with facial fracture and registered in the National Health Insurance Research Database of Taiwan between 1997 and 2011. The epidemiological characteristics of this cohort were analyzed, including the etiology, fracture site, associated injuries, and sex and age distributions. A total of 6,013 cases were identified that involved facial fractures. Most patients were male (69.8%), aged 18-29 years (35.8%), and had fractures caused by road traffic accidents (RTAs; 55.2%), particularly motorcycle accidents (31.5%). Falls increased in frequency with advancing age, reaching 23.9% among the elderly (age > 65 years). The most common sites of involvement were the malar and maxillary bones (54.0%), but nasal bone fractures were more common among those younger than 18 years. Most facial injuries in Taiwan occur in young males and typically result from RTAs, particularly involving motorcycles. However, with increasing age, there is an increase in the proportion of facial injuries due to falls.

2015-01-01

Previous case reports and small studies have suggested that 3-hydroxy-3-methylglutaryl-CoA reductase inhibitors (HMG-CoA-Is) may increase the risk of tendon rupture. We conducted a population-based retrospective cohort evaluation to better assess this relationship. From approximately 800,000 enrollees of a private insurance database, those who were aged ≤64 years with at least 1 year of continuous enrollment were selected. Exposure was defined as initiation of HMG-CoA-I after the beginning of the study period. Each exposed person was matched with 2 controls of similar age and gender. Baseline characteristics, including known risk factors for tendon rupture, were compared between exposed and control cohorts with fidelity to the study's matched design. After adjusting for differences in follow-up and baseline characteristics, incidence rate ratios for tendon rupture was assessed in HMG-CoA-I users and nonusers. A total of 34,749 exposed patients were matched with 69,498 controls. There was no difference in the occurrence of tendon ruptures in HMG-CoA-I users versus nonusers. The results remained unchanged after adjustment for age and gender. In conclusion, this population-based retrospective cohort evaluation suggests that use of HMG-CoA-Is as a group are not associated with tendon rupture.

This retrospective longitudinal study evaluated the clinical performance of bonded ceramic inlays/onlays, placed by the first author in his private practice, in a 5 to 18-year period. The patients evaluated had been treated in the office for at least 7 years and were still in the practice up to year 2013. 130 randomly selected patients agreed to participate in the study. 93 bonded ceramic inlays/onlays (BCRs), were placed on posterior teeth in 47 subjects. Gender, age, tooth preparation, number, type, extent, location, quality and survival of the restorations, ceramic materials, luting resins cements, parafunctional habits, secondary caries and maintenance therapy were the variables evaluated. Cohen 's Kappa coefficient, on the quality analysis of the restorations, ranged from 0.78 to 1. Fisher 's exact test, Chi Square test, Kruskal-Wallis test and Mann-Whitney non-parametric test were indicated to analyze significant differences. At the initial examination, 87 (93.5%) restorations were in function and six failed (6.5%). 81 (93%) were rated as clinical successes. The observed mean survival time of those that remained functional was 11 years. The standard deviation was 4 years, with a 95% CI for the overall observed mean survival time (10 years-11 years, 9 months). 87 of 93 BCRs had a functional success of 93.5%, with an observed mean survival of 11 years. The clinical performance of bonded ceramic onlays was very acceptable. Bonded ceramic onlays showed a predictable, esthetic, and functional treatment, with acceptable longevity.

To investigate the association between the trends of CT utilisation in an emergency department (ED) and changes in clinical imaging practice and patients' disposition. A hospital-based retrospective observational study of a public 1520-bed referral medical centre in Taiwan. Adult ED visits (aged ≥18 years) during 2009-2013, with or without receiving CT, were enrolled as the study participants. For all enrolled ED visits, we retrospectively analysed: (1) demographic characteristics, (2) triage categories, (3) whether CT was performed and the type of CT scan, (4) further ED disposition, (5) ED cost and (6) ED length of stay. In all, 269 239 adult ED visits (148 613 male patients and 120 626 female patients) were collected during the 5-year study period, comprising 38 609 CT scans. CT utilisation increased from 11.10% in 2009 to 17.70% in 2013 (trend test, p<0.001). Four in 5 types of CT scan (head, chest, abdomen and miscellaneous) were increasingly utilised during the study period. Also, CT was increasingly ordered annually in all age groups. Although ED CT utilisation rates increased markedly, the annual ED visits did not actually increase. Moreover, the subsequent admission rate, after receiving ED CT, declined (59.9% in 2009 to 48.2% in 2013). ED CT utilisation rates increased significantly during 2009-2013. Emergency physicians may be using CT for non-emergent studies in the ED. Further investigation is needed to determine whether increasing CT utilisation is efficient and cost-effective.

The objective of the study was to describe the age distribution and to evaluate the role of prognostic value of age on survival in patients diagnosed with olfactory neuroblastoma (ONB). A population-based retrospective analysis was conducted. The population-based study of patients in the Surveillance, Epidemiology, and End Results (SEER) tumor registry, who were diagnosed with ONB from 1973 to 2014, were retrospectively analyzed. The cohort included 876 patients with a median age of 54 years. There was a unimodal distribution of age and ONBs most frequently occurred in the fifth to sixth decades of life. Kaplan-Meier analysis demonstrated overall survival (OS) and cancer-specific survival (CSS) rates of 69% and 78% at 5 years. Multivariable Cox regression analysis showed that age, SEER stage, and surgery were independent prognostic factors for CSS. The risk of overall death and cancer-specific death increased 3.1% and 1.6% per year, respectively. Patients aged >60 years presented significantly poor OS and CSS compared with patients aged ≤60 years, even in patients with loco-regional disease or in those treated with surgery. This study highlights the growing evidence that there is a unimodal age distribution of ONB and that age is an important adverse prognostic factor.

The aim of the present study was to evaluate retrospectively the clinical and radiographic behaviour of four commercially-available short implants with different macrodesigns and microdesigns in areas in which the height of the bone was reduced. We took into account the success and survival, peri-implant crestal bone loss, and the level of probing at which the gum bled. Patients were included if they had been given one or more short implants (≤8.5mm long) in the posterior jaws at least three years earlier. Three hundred and ninety-one short implants were placed in 170 subjects, and were divided in four groups based on the brand of implant. The implants were evaluated one, two, and three years after they had been inserted. Short implants had a three-year survival and success rate of 90% in all groups, and bone loss was acceptable after three years with no significant differences between them. These results support the use of short implants as an effective and safe treatment. However, within the limitations of this study, the design of the implant does seem to influence the behaviour of peri-implant bone at the crestal level. Copyright © 2017. Published by Elsevier Ltd.

Firearm and Nonfirearm Homicide in 5 South African Cities: A Retrospective Population-Based Study

Thompson, Mary Lou; Myers, Jonathan E.

2014-01-01

Objective. We assessed the effectiveness of South Africa’s Firearm Control Act (FCA), passed in 2000, on firearm homicide rates compared with rates of nonfirearm homicide across 5 South African cities from 2001 to 2005. Methods. We conducted a retrospective population-based study of 37 067 firearm and nonfirearm homicide cases. Generalized linear models helped estimate and compare time trends of firearm and nonfirearm homicides, adjusting for age, sex, race, day of week, city, year of death, and population size. Results. There was a statistically significant decreasing trend regarding firearm homicides from 2001, with an adjusted year-on-year homicide rate ratio of 0.864 (95% confidence interval [CI] = 0.848, 0.880), representing a decrease of 13.6% per annum. The year-on-year decrease in nonfirearm homicide rates was also significant, but considerably lower at 0.976 (95% CI = 0.954, 0.997). Results suggest that 4585 (95% CI = 4427, 4723) lives were saved across 5 cities from 2001 to 2005 because of the FCA. Conclusions. Strength, timing and consistent decline suggest stricter gun control mediated by the FCA accounted for a significant decrease in homicide overall, and firearm homicide in particular, during the study period.

Clozapine has been regarded as the gold standard for patients with treatment-resistant schizophrenia, but a recent network meta-analysis has questioned its relative superiority over other second-generation antipsychotics (SGAs) such as olanzapine and risperidone. We conducted a retrospective mirror-image study of clozapine vs other SGAs to evaluate real-world effectiveness of clozapine in terms of the duration of hospitalization and seclusion, both of which represent a critical outcome. We included all patients who initiated clozapine at the Yamanashi Prefectural KITA Hospital and had continued to take any SGA(s) other than clozapine for at least 1 year before the initiation of clozapine. We obtained data on hospitalization and seclusion during 1 year of SGA treatment (SGA phase) and 1 year after the treatment was switched to clozapine (clozapine phase). The study included 35 patients (21 men, 31 with schizophrenia, 4 with schizoaffective disorder) with the average ± SD age of 37.3 ± 11.1 years. The results indicated that total hospitalization days did not differ significantly between SGA and clozapine treatment. However, total duration of seclusion was significantly shorter in the clozapine phase than in the SGA phase. Furthermore, the number of patients who were secluded at least once was significantly smaller in the clozapine phase than in the SGA phase. The results were essentially unchanged when outlier patients were excluded and only when patients taking olanzapine and/or risperidone during the SGA phase were considered. Although the findings from this retrospective analysis need to be further tested in prospective trials, they endorse the relative effectiveness of clozapine over other SGAs in the real world.

The objective of this study was to compare implant survival and success rates, peri-implant parameters, and prosthodontic maintenance efforts for implant-supported telescopic crown overdentures and bar overdentures to restore maxillary edentulism. This retrospective clinical study involved patients with maxillary edentulism who were fitted with implant-supported overdentures from January 2004 to June 2007. During a 5- to 8-year follow-up period, the implant survival and success rates, biologic and mechanical complications, prosthodontic maintenance, and patient satisfaction were retrospectively analyzed. The data were evaluated statistically and P < .05 was considered to be statistically significant. Forty-four patients with maxillary edentulism received implant-supported removable overdentures. Twenty-one patients chose telescopic crown overdentures and 23 patients chose bar overdentures. A total of 41 patients and 201 implants were available for follow-up. The implant survival and success rates, average bone resorption, and subjective patient satisfaction scores showed no difference between the telescopic crown and the bar overdenture group at follow-up. However, there were higher values for Plaque and Calculus Indexes in the bar group compared with the telescopic crown group, and these values showed a statistically significant difference annually from the 3-year follow-up (P < .05). Each year, the number of prosthodontics maintenance procedures per patient did not significantly differ between the telescopic crown (approximately 0.36 to 0.58) and bar groups (approximately 0.30 to 0.49) (P = .16). Although there were higher plaque and calculus levels in the bar group and more maintenance was required for the telescopic crown group, overdentures provided a healthy peri-implant structure for implants in both groups. Implant-supported telescopic crown or bar overdentures can provide a good treatment option for patients with edentulous maxillae.

Gestational diabetes has been associated with obesity later in life. However, reported results have not been consistent and the methods used have shown weakness. To analize prospective and retrospective cohort studies that assess the gestational diabetes effects on adiposity indicators in the offspring during their first 18 years. A search was made for prospective or retrospective cohort studies registered in Medline/ Pubmed database, from January 2011 to September 2013 that evaluated the gestational diabetes effects on adiposity indicators at birth or after birth. Eleven studies met the inclusion criteria. A total of 472,959 pairs of mother and child were studied. Children age at the moment of evaluation ranged from birth to 18 years. In nine out of eleven articles an association between gestational diabetes and adiposity indicators was observed. In seven studies adjustments for potential confounders (pre gestational BMI, maternal age) were made. In five of those an association between gestational diabetes and adiposity was found. The results of this review indicate that the evidence showing that gestational diabetes increase adiposity indicators later in life is moderate. Copyright AULA MEDICA EDICIONES 2014.

Bilingualism and Cognitive Decline: A Story of Pride and Prejudice.

Woumans, Evy; Versijpt, Jan; Sieben, Anne; Santens, Patrick; Duyck, Wouter

2017-01-01

In a recent review, Mukadam, Sommerlad, and Livingston (2017) argue that bilingualism offers no protection against cognitive decline. The authors examined the results of 13 studies (five prospective, eight retrospective) in which monolinguals and bilinguals were compared for cognitive decline and onset of dementia symptoms. Analysis of four of the five prospective studies resulted in the conclusion that there was no difference between monolinguals and bilinguals, whereas seven of the eight retrospective studies actually showed bilingualism to result in a four-to-five year delay of symptom onset. The authors decided to ignore the results from the retrospective studies in favor of those from the prospective studies, reasoning that the former may be confounded by participants' cultural background and education levels. In this commentary, we argue that most of these studies actually controlled for these two variables and still found a positive effect of bilingualism. Furthermore, we argue that the meta-analysis of the prospective studies is not complete, lacking the results of two crucial reports. We conclude that the literature offers substantial evidence for a bilingual effect on the development of cognitive decline and dementia.

To study effectiveness of surgery and watchful waiting in localized laryngeal amyloidosis, retrospective case series. This retrospective study comprises all consecutive patients with localized laryngeal amyloidosis surgically treated in a tertiary hospital between 1994 and February 2016. Recurrence rate, revision surgery, progression to systemic amyloidosis, and changes in voice were monitored yearly. Eighteen patients were included. Seven women and eleven men had a median age 50 years (range 21-77 years) and median follow-up 6.4 years (2.4-17 years). Amyloid was located in subglottis (5), glottis (8), false vocal folds (8) and other supraglottic areas (5), in more than one laryngeal region (13) and bilaterally (12). Cold steel excision was used at the glottis; CO2 laser excision, sometimes assisted by microdebrider, at other laryngeal areas. Eleven patients needed revision surgery, ten within the first 4 years after surgical treatment. One patient needed his first revision surgery after 11 years. Five patients needed a second revision within 6 years after initial diagnosis. Two patients needed a third revision. Indications for first revision surgery were progression (8) with dysphonia (7), dyspnea (2), dysphagia (1), exclusion of malignancy (1), and aphonia (1). No patient developed systemic amyloidosis during follow-up. Although local progression of amyloid necessitates revision surgery once or twice in the first 4-6 years, progression slows down thereafter. Late progression, however, remains possible.

Predictors of mortality among HIV infected patients taking antiretroviral treatment in Ethiopia: a retrospective cohort study

PubMed Central

2012-01-01

Background Studies indicate that there is high early mortality among patients starting antiretroviral treatment in sub-Saharan Africa. However, there is paucity of evidence on long term survival of patients on anti-retroviral treatment in the region. The objective of this study is to examine mortality and its predictors among a cohort of HIV infected patients on anti-retroviral treatment retrospectively followed for five years. Methods A retrospective cohort study was conducted among HIV infected patients on ART in eastern Ethiopia. Cox regression and Kaplan-Meier analyses were performed to investigate factors that influence time to death and survival over time. Result A total of 1540 study participants were included in the study. From the registered patients in the cohort, the outcome of patients as active, deceased, lost to follow up and transfer out was 1005 (67.2%), 86 (5.9%), 210 (14.0%) and 192 (12.8%) respectively. The overall mortality rate provides an incidence density of 2.03 deaths per 100 person years (95% CI 1.64 - 2.50). Out of a total of 86 deaths over 60 month period; 63 (73.3%) died during the first 12 months, 10 (11.6%) during the second year, and 10 (11.6%) in the third year of follow up. In multivariate analysis, the independent predictors for mortality were loss of more 10% weight loss, bedridden functional status at baseline, ≤ 200 CD4 cell count/ml, and advanced WHO stage patients. Conclusion A lower level of mortality was detected among the cohort of patients on antiretroviral treatment in eastern Ethiopia. Previous history of weight loss, bedridden functional status at baseline, low CD4 cell count and advanced WHO status patients had a higher risk of death. Early initiation of ART, provision of nutritional support and strengthening of the food by prescription initiative, and counseling of patients for early presentation to treatment is recommended.

Designing a household survey to address seasonality in child care arrangements.

Schmidt, Stefanie R; Wang, Kevin H; Sonenstein, Freya L

2008-04-01

In household telephone surveys, a long field period may be required to maximize the response rate and achieve adequate sample sizes. However, long field periods can be problematic when measures of seasonally affected behavior are sought. Surveys of child care use are one example because child care arrangements vary by season. Options include varying the questions posed about school-year and summer arrangements or posing retrospective questions about child care use for the school year only. This article evaluates the bias associated with the use of retrospective questions about school-year child care arrangements in the 1999 National Survey of America's Families. The authors find little evidence of bias and hence recommend that future surveys use the retrospective approach.

The National Oral Health Screening Program (NOHSP) is a general population-based program in Korea. The objective of this study was to assess the association between participation in the NOHSP and dental visit for periapical abscess (PA) and advanced periodontal disease (APD) among Korean adults. Data were obtained for subjects from the National Health Insurance database. The authors conducted a retrospective cohort study of 9358 randomly selected subjects who were between 40 and 64 years old in 2002. The outcomes of dental visit for PA or APD from the years 2003 to 2007 were compared between the screening and nonscreening groups. The nonscreening group had 19% higher risk of PA and 15% higher risk of APD. This study suggests that the NOHSP may decrease the risk of dental visit because of PA and APD by preventing the progress of lesion to the advanced stage among Korean adults.

Thyroid malignancy among goitrous thyroid lesions: a review of hospital-based studies in Malaysia and Myanmar.

PubMed

Htwe, T T

2012-03-01

Endemic goitre is a major concern in many parts of the world, including Southeast Asia. Goitrous thyroid lesion is postulated as a precursor lesion to thyroid cancer (TC). This paper reviews the prevalence rates and characteristics of TC among cases of goitrous thyroid-swelling in different parts of Malaysia and Myanmar. Recorded data from hospital-based retrospective studies of thyroid cases, whose study periods ranged from three to 11 years, were analysed. These included research findings from the author's publications as well as other published review articles of retrospective analyses. The incidence of TC varies among gender, age, race/ethnicity and histological type. There appears to be a higher rate of occurrence among females aged 21-60 years. Papillary thyroid carcinoma is the more common histological type compared to follicular cancer. This review also presents a descriptive analysis and discussion on studies conducted in other countries. Further exploration is warranted in order to uncover the possible risk factors for the rising incidence of TC.

Objective This study aims to analyze the clinical and endoscopic presentations of upper gastrointestinal bleeding (UGIB) in the Chinese children. Methods A 10-year retrospective study was made on children with UGIB and undertaken esophagogastroduodenoscopy (EGD) from 4 tertiary referral centers in China. Results Of the 1218 children studied, the bleeding source was found in 76.4%. Erosive gastritis was the most common endoscopic finding (33.5%), followed by duodenal ulcer (23.2%). The proportion of erosive gastritis decreased with age (correlation coefficient = -0.787), and duodenal ulcer increased with age (correlation coefficient = 0.958). The bleeding source was more likely to be determined in children having EGDs within 48 hours (80.6% vs 67.9%). Conclusions In Chinese children with UGIB, erosive gastritis and duodenal ulcer were the leading causes, and their proportions varied with age. EGDs performed within 48 hours may improve the possibility of finding the source of bleeding. © The Author(s) 2015.

2002-01-01

Objectives To assess whether prospective, observational study procedures, including questionnaires and audio recording, are associated with different patterns of physician diagnostic decision making and antibiotic prescribing. Data Sources/Setting (1) Survey data from a prospective observational study of treatment patterns for children with acute upper respiratory illnesses (10/96–3/97) and (2) retrospective medical record abstraction data of nonobserved encounters for the same problems occurring during (10/96–3/97) and one year after (10/97–3/98) the observational study period. Ten pediatricians in two community practices were studied. Study Design Patterns of diagnoses recorded in the medical record and antibiotics ordered for visits occurring outside of the observational study (same time period and one year later) were compared with the pattern of diagnoses and antibiotics ordered during the observational study. Data Collection/Extraction Methods For the observational study (10/96–2/97), diagnosis and treatment choices were obtained from questionnaires completed by physicians immediately following the visit. For the nonstudy encounters (10/96–3/97 and 10/97–3/98), data were abstracted from medical records one year after the observational study was completed. Principal Findings The proportion of viral cases in which an antibiotic was prescribed was 29 percentage points lower for the observational study compared to the retrospective analysis (p <.05). In one of two study sites, the proportion of cases assigned a bacterial diagnosis was 29 percentage points lower in the observational study period compared to the retrospective study (p <.05). Conclusions Observational study procedures including questionnaires and audio recording can affect antibiotic prescribing behavior. Future observational studies aimed at examining the frequency of inappropriate antibiotic prescribing should measure and adjust for the Hawthorne effect; without such adjustments, the results will likely underestimate the true degree of the problem. Future interventions aimed at decreasing inappropriate antibiotic prescribing should consider “harnessing” the Hawthorne effect through performance feedback to participating physicians.

This study aims to evaluate and analyze the clinical features and outcomes of oral and oropharyngeal squamous cell carcinoma (SCC) in patients < 45-years old in our center. A retrospective analysis was conducted using the records of patients diagnosed with oral and oropharyngeal SCC between 1998 and 2011 in the University Hospital of Granada (Spain). The analysis identified 33 patients with oral and oropharyngeal SCC with an age of <45 years. Moreover, during the years studied, a further 472 patients were diagnosed with oral and oropharyngeal SCC in our center. Thus, 100 SCC patients with an age of >45 years were randomly selected from the same database. A retrospective analysis was conducted to determine specific features including sites of occurrence, risk factors, sex distribution, socio-economic status, T stage at diagnosis, nodal involvement, degree of tumor differentiation, locoregional failure and overall survival at 5 years was. Further, the results of both groups were compared. The male-female ratio was 1.2:1 in the group of young adults and 2.03:1 in the group of patients with an age of >45 years. No significant differences were found in terms of site, nodal involvement, locoregional failure, and overall survival. However, there were statistically significant differences between the two groups in terms of features such as risk factors, socio-economic status, T stage at diagnosis, and degree of tumor differentiation. The overall 5-year survival rate was 62% for patients >45 years old, whilst for the group of young adults this rate was 48.4% (p= 0.17). The poor association between the common risk factors and oral and oropharyngeal cancers in young adults suggests that other pathogenic mechanisms should be investigated. For young patients, the data show evidence of poorer outcomes in terms of overall survival (p=0.17), and locoregional failure (p=0.23). Nevertheless, the literature shows that the results in this field are particularly inconsistent, and further research is therefore needed to provide more in-depth knowledge of the disease in this age group.

This retrospective study investigated the clinical characteristics and outcomes of second malignant neoplasms (SMNs) in survivors of childhood cancer from multiple institutions in Korea. A total of 102 patients from 11 institutions who developed SMN after childhood cancer treatment between 1998 and 2011 were retrospectively enrolled. The most common primary malignant neoplasms (PMNs) were central nervous system (CNS) tumors (n = 17), followed by acute lymphoblastic leukemia (n = 16), non-Hodgkin lymphoma (n = 13), and osteosarcoma (n = 12). The most common SMNs were therapy-related myeloid neoplasms (t-MNs; acute myeloid leukemia [AML], 29 cases; myelodysplastic syndrome [MDS], 12 cases), followed by thyroid carcinomas (n = 15) and CNS tumors (n = 10). The median latency period was 4.9 years (range, 0.5-18.5 years). Among 45 patients with solid tumors defined as an SMN, 15 (33%) developed the lesion in a field previously subjected to radiation. The 5-year overall survival (OS) rate of patients with an SMN was 45% with a median follow-up time of 8.6 years. Patients with AML, MDS, and CNS tumors exhibited the poorest outcomes with 5-year OS rates of 18%, 33%, and 32%, respectively, whereas those with second osteosarcoma showed comparable outcomes (64%) to patients with primary counterpart and those with second thyroid carcinoma had a 100% OS rate. Further therapeutic efforts are recommended to improve the survival outcomes in patients with SMNs, especially in cases with t-MNs and CNS tumors.

This report retrospectively analyzed the outcome of 91 patients aged 60 years or older with refractory/relapsed (R/R) classical Hodgkin's lymphoma (cHL) who underwent autologous stem cell transplantation (ASCT) between 1992 and 2013 and were reported to the French Society of Bone Marrow Transplantation and Cell Therapies registry. The median age at transplant was 63 years. The majority of patients exhibited disease chemosensitivity to salvage treatment (57 complete responses, 30 partial responses, 1 progressive disease and 3 unknown). The most frequent conditioning regimen consisted of BCNU, cytarabine, etoposide, melphalan (BEAM) chemotherapy (93%). With a median follow-up of 54 months, 5-year estimates of overall survival (OS) and progression free survival (PFS) for the entire group were 67 and 54%, respectively. Despite the missing data, in univariate analysis, the number of salvage chemotherapy lines (1-2 versus ⩾3) significantly influenced the OS, unlike the other prognostic factors (stage III-IV at relapse, disease status before ASCT and negative positron emission tomography (PET) scan) encountered in younger patients. In spite of its limitations, this retrospective study with a long-term follow-up suggests that ASCT is a valid treatment option for chemosensitive R/R cHL in selected elderly patients, with an acceptable rate of toxicity.

Although recent short-term cross-sectional studies have revealed that chronic periodontitis (CP) may be a risk factor for increased cognitive impairment in patients with Alzheimer's disease (AD), systematic reviews and long-term longitudinal studies have provided less clear evidence regarding the relationship between CP and AD. Therefore, we conducted a retrospective cohort study using the National Health Insurance Research Database (NHIRD) of Taiwan to determine whether patients with CP are at increased risk of developing AD. We conducted a retrospective matched-cohort study using the NHIRD of Taiwan. We identified 9291 patients newly diagnosed with CP between 1997 and 2004. A total of 18,672 patients without CP were matched to the patient cohort according to sex, age, index year, co-morbidity and urbanisation level. Cox proportional hazards regression analyses were performed to evaluate the subsequent risk of AD. Patients with CP had a higher prevalence of hyperlipidaemia, depression, traumatic brain injury and co-morbidities, as well as higher urbanisation levels, than those in the unexposed cohort (all p < 0.01). At the final follow-up, totals of 115 (1.24%) and 208 (1.11%) individuals in the CP exposed and unexposed groups, respectively, had developed AD. Patients with 10 years of CP exposure exhibited a higher risk of developing AD than unexposed groups (adjusted HR 1.707, 95% CI 1.152-2.528, p = 0.0077). Our findings demonstrate that 10-year CP exposure was associated with a 1.707-fold increase in the risk of developing AD. These findings highlight the need to prevent progression of periodontal disease and promote healthcare service at the national level.

Animal bite wounds are a significant problem, which have caused several preventable child deaths in clinical practice in the past. The majority of bite wounds is caused by dogs and cats, and also humans have to be considered to lead to those extreme complicated diagnosis in the paediatric patient population. Early estimation of infection risk, adequate antibiotic therapy and, if indicated, surgical treatment, are cornerstones of successful cures of bite wounds. However, antibiotic prophylaxis and wound management are discussed controversially in the current literature. In our study, we retrospectively investigated the bite source, infection risk and treatment options of paediatric bite wounds. A total of 1592 paediatric trauma patients were analysed over a period of 19 years in this retrospective study at a level I trauma centre, Department of Trauma Surgery, Medical University of Vienna, Austria. Data for this study were obtained from our electronic patient records and follow-up visits. In our database, all paediatric patients triaged to our major urban trauma centre have been entered retrospectively. During the 19-year study period, 1592 paediatric trauma patients met the inclusion criteria. The mean age was 7.7 years (range 0-18.9), 878 (55.2%) were males and 714 (44.8%) were females. In our study population, a total of 698 dog bites (43.8%), 694 human bites (43.6%), 138 other bites (8.7%) and 62 cat bites (3.9%) have been observed. A total of 171 wounds (10.7%) have been infected. Surgical intervention was done in 27 wounds (1.7%). Gender-related incidence in bite wounds for dog and cat could be detected. Second, our findings for originator of bite wounds reflect the findings in the published literature. Total infection rate reached 10.7%, primary antibiotic therapy was administered in 221 cases (13.9%) and secondary antibiotic therapy in 20 (1.3%) cases. Observed infection rate of punctured wounds and wounds greater than 3 cm was 3 times higher than for all other wounds. Our findings need to be proven in further prospective clinical trials.

Alcohol intake has been associated with reduced incidence of common cold symptoms in 2 European studies. However, no study has addressed the association between the frequency of alcohol intake and the incidence of common cold. This study aimed to investigate the association between the amount and frequency of alcohol drinking and the retrospective prevalence of common cold in Japanese men. This retrospective study included men who participated in an annual health examination conducted in Sendai, Japan. The frequency of common cold episodes in the previous year was self-reported. The weekly frequency and amount of alcohol consumed, as well as the type of alcoholic drink, were reported by a brief-type self-administered diet history questionnaire. Logistic regression models were used to analyze the association between the amount and frequency of alcohol intake and the retrospective prevalence of common cold. Among 899 men, 83.4% of the subjects reported drinking alcohol, and 55.4% of the subjects reported having experienced at least one episode of common cold in the previous year. Compared with non-drinkers, the adjusted odds ratios (ORs) with 95% confidence intervals (CIs) for having had 1 or more episodes of common cold during the past year across categories of alcohol intake frequency of 3 or less, 4-6, and 7 days/week were 0.827 (0.541-1.266), 0.703 (0.439-1.124), and 0.621 (0.400-0.965), respectively (P for trend = 0.025); the adjusted ORs with 95% CIs for having had of 2 or more episodes of common cold across the same categories were 0.642 (0.395-1.045), 0.557 (0.319-0.973), and 0.461 (0.270-0.787), respectively (P for trend = 0.006). Compared with subjects who consumed 11.5-35.8 g of alcohol per day, the non-drinkers were significantly more likely to experience 2 or more episodes of common cold (OR, 1.843; 95% CI, 1.115-3.047). The frequency, not the amount, of alcohol intake was significantly related to lower prevalence of self-reported common cold episodes in Japanese men.

Scientific data about the long-term survival of teeth treated with cast post and cores are scarce. Retrospective studies often use different target events for their analyses. A comparison is therefore complicated. For associated tooth-, jaw-, and patient-related factors little evidence exists as to their effect on survival. The purpose of this study was to extend the knowledge on the survival of teeth treated with cast post and cores for observation periods of more than 10 years. A decrease or increase in survival times according to the presence or absence of associated parameters needs to be evaluated. A retrospective evaluation was conducted of all cast post and cores inserted in 1 university clinic between January 1992 and June 2011. A Kaplan-Meier survival analysis was carried out by using extraction as the target event. The survival curves for different tooth types, the presence or absence of adjacent teeth, and the prosthetic restoration of the respective jaws were compared by using the log-rank test (α=.05). A Cox regression model was calculated for multivariate analyses. A total of 717 cast post and cores for 343 patients were recorded. The mean survival time was 13.5 years. A statistically significant decrease in survival times was found for canines (11.9 years) and premolars (13.4 years) versus molars (14.1 years), no adjacent teeth (10.6 years) versus at least 1 adjacent tooth (13.8 years), and the restoration with removable dental prostheses (12.5 years) versus fixed dental prostheses and single crowns (13.9 years). The largest reduction in survival time was found for teeth being used as an abutment for a double crown-retained removable partial dental prosthesis (telescopic denture) (9.8 years). Tooth type and adjacent tooth status remained as significant variables within the multivariate Cox regression model. Cast post and cores have an acceptable long-term survival time. Because different factors may influence survival, considering these factors in treatment planning may increase the long-term success of these restorations.

The aim of this study was to analyze the prevalence of depression, anxiety, and adjustment disorders in women within the year following miscarriage in Germany. This study included women between the ages of 16 and 45 with a first pregnancy terminated by spontaneous abortion between January 2007 and December 2015 (index date). These women were followed in 262 gynecological practices. Women with a spontaneous abortion were matched (1:1) with pregnant women without spontaneous abortion by age, index year, diagnosis of female infertility prior to the index date, procreative management prior to the index date, and physician. This retrospective cohort study included 12,158 women with a spontaneous abortion and 12,158 pregnant women without a spontaneous abortion. The mean age was 31.6 (SD: 5.5).years. One year after the index date, 8.9% of women with spontaneous abortion and 5.7% of controls were diagnosed with depression, anxiety, or adjustment disorder. Individuals who had previously undergone a spontaneous abortion were more likely to have one of these three psychiatric disorders compared to controls (OR = 1.53). Similar results were found in the age groups 21-30 and 31-40. Spontaneous abortion is associated with an increased prevalence of developing psychiatric diseases within the first year.

2004-01-01

This study used a retrospective narrative procedure to examine the critical events that influence reactions and adjustment to euthanasia-related work of 35 employees who have stayed in the animal care and welfare field for at least 2 years. The study analyzed adjustment trajectory graphs and interview notes to identify turning-point events that spurred either a positive or negative change in shelter workers' psychological well-being. Analysis of the identified turning-point events revealed 10 common event themes that have implications for a range of work, personnel, and organizational practices. The article discusses implications for shelter, employee, and animal welfare.

1992-09-10

Based on a retrospective study of the case records of the primary health care services in a small Norwegian coastal community (Finnøy), we found an incidence of 13% for lower respiratory infections in persons aged 70 years or more. Most often the initial medication was penicillin. In 23% of recorded episodes, medication was changed, owing to unsatisfactory response. Overall mortality in the group was 9%. Three out of five deaths occurred in patients terminally ill from other diseases at the time the respiratory infection started. Problems related to diagnosis, management and prevention are discussed.

2017-01-01

Background In Vietnam, dengue fever is a major health concern, yet comprehensive information on its economic costs is lacking. The present study investigated treatment costs associated with dengue fever from the perspective of health care provision. Methods This retrospective study was conducted between January 2013 and December 2015 in Cu Chi General Hospital. The following dengue-related treatment costs were calculated: hospitalisation, diagnosis, specialised services, drug usage and medical supplies. Average cost per case and treatment cost across different age was calculated. Results In the study period, 1672 patients with dengue fever were hospitalised. The average age was 24.98 (SD = 14.10) years, and 47.5% were males (795 patients). Across age groups, the average cost per episode was USD 48.10 (SD = 3.22). The highest costs (USD 56.61, SD = 48.84) were incurred in the adult age group (> 15 years), and the lowest costs (USD 30.10, SD = 17.27) were incurred in the paediatric age group (< 15 years). Conclusion The direct medical costs of dengue-related hospitalisation place a severe economic burden on patients and their families. The probable economic value of dengue management in Vietnam is significant. PMID:28814934

To study the characteristics of clinical presentations and treatment outcome of patients with HIV infection who developed cytomegalovirus(CMV) retinitis. A retrospective study for the period 1986-97 at the regional Unit of Infectious Diseases, Newcastle General Hospital; a teaching hospital in the north-east of England. Twenty-seven patients with advanced HIV disease and clinically confirmed CMV retinitis were studied. The mean age was 40.8 years, standard deviation +/-6.3 years. The male : female ratio was 25 : 2. Twenty-six of the patients were white Caucasians and one was of Afro-Caribbean origin. The median time between the first AIDS-defining diagnosis and development of CMV retinitis was 1.5 years and the CD4+ cell count at the time of diagnosis of CMV retinitis was 7/mm3. After 14 months of treatment. 80% of patients on mono antiretroviral therapy had impairment of sight (visual acuity 3/60) versus 30% for those on triple antiretroviral therapy. In the same period, the survival rate was 18 versus 70% for mono versus triple antiretroviral therapy, respectively. The outcome for patients with CMV retinitis was significantly better for those who were on triple than for those on mono antiretroviral therapy.

This study aimed to evaluate the demographic, clinical features, laboratory data, pathology and other survey in pediatric patients with cryofibrinogenemia. A 12-year retrospective chart review identified eight pediatric patients at Mackay Memorial Hospital, Taipei, Taiwan. The female-to-male ratio was 3:1. The mean age at symptom onset and of diagnosis was 10.3 ± 4.6 years and 12.3 ± 4 years, respectively. One child (12.5%) had primary cryofibrinogenemia. The common symptoms were purpura, arthralgia, and muscle weakness (100%). On laboratory examination, cryofibrinogen was positive in all patients. All patients had increased anti-thrombin III while 87.5% and 62.5% had abnormal protein S and protein C, respectively. All eight also complained of neurologic symptoms. One had vertebral artery narrowing, two showed increased T2-weighted signal intensity on the thalamus or white matter, and one had acute hemorrhagic encephalomyelitis on brain magnetic resonance imaging. This study reports on the presentations of cryofibrinogenemia, which is rare in children. Most cases are associated with autoimmune disease and have severe and complex presentations. Central nervous system involvement is common.

2009-01-01

In this 31-year retrospective study, we examined the influence of meteorology on airborne Betula spp. (birch) pollen concentrations in Turku, Finland. The seasonal incidence of airborne birch pollen in Turku occurred over a brief period each year during spring (April 30 – May 31). Mean peak concentrations were restricted to May (May 5 to 13). Statistically significant increases in the annual accumulated birch pollen sum and daily maximum values were observed over the study period. Birch pollen counts collected in April were retrospectively shown to increase over the duration of the study. Increases in April temperature values were also significantly associated with the earlier onset of the birch pollen season. Furthermore, the number of days where daily birch pollen concentrations exceeded 10 and 1,000 grains/m3 also increased throughout the study period. These data demonstrate that increases in temperature, especially during months preceding the onset of the birch pollen season, favor preseason phenological development and pollen dispersal. Birch pollen derived from other geographical locations may also contribute to the aerospora of Turku, Finland. To date, the public health burden associated with personal exposure to elevated birch pollen loads remains unclear and is the focus of future epidemiological research. PMID:19578456

Optical Coherence Tomography Angiography Reveals Mature, Tangled Vascular Networks in Eyes With Neovascular Age-Related Macular Degeneration Showing Resistance to Geographic Atrophy.

To demonstrate a vascular pattern seen on optical coherence tomography angiography (OCTA) that appears to correlate with reduced rates of geographic atrophy (GA) in eyes receiving long-term anti-vascular endothelial growth factor (VEGF) treatment for neovascular age-related macular degeneration (AMD). Non-consecutive, retrospective cohort study. Patients were included if they had received more than 50 anti-VEGF injections during a period of at least 4 years for neovascular AMD in at least one eye, with absence or minimal progression of GA. Clinical charts and imaging were reviewed retrospectively; study eyes underwent OCTA. Nine eyes of eight patients were included. Mean age was 82 years, and mean follow-up of study eyes 9.1 years; study eyes received a mean of 65.8 injections. OCTA revealed tangled networks of neovessels associated with type 1 lesions. With prolonged anti-VEGF treatment, GA appears to occur less commonly in eyes with type 1 neovascularization. OCTA shows mature tangled vessels with substantial flow within type 1 lesions. Mature, tangled networks may be associated with a decreased likelihood of developing GA despite the presence of choriocapillaris atrophy. Copyright 2015, SLACK Incorporated.

Correlates of achievement in the basic science years in medical school and on the Step 1 of the United States Medical Licensing Examination® (USMLE®), (Step 1) in relation to preadmission variables have been the subject of considerable study. Preadmissions variables such as the undergraduate grade point average (uGPA) and Medical College Admission Test® (MCAT®) scores, solely or in combination, have previously been found to be predictors of achievement in the basic science years and/or on the Step 1. The purposes of this retrospective study were to: (1) determine if our statistical analysis confirmed previously published relationships between preadmission variables (MCAT, uGPA, and applicant pool size), and (2) study correlates of the number of failures in five M1 courses with those preadmission variables and failures on Step 1. Statistical analysis confirmed previously published relationships between all preadmission variables. Only one course, Microscopic Anatomy, demonstrated significant correlations with all variables studied including the Step 1 failures. Physiology correlated with three of the four variables studied, but not with the Step 1 failures. Analyses such as these provide a tool by which administrators will be able to identify what courses are or are not responding in appropriate ways to changes in the preadmissions variables that signal student performance on the Step 1. © 2014 American Association of Anatomists.

Predictors of Loss to Follow-up Among HIV-infected Patients in a Rural South-Eastern Nigeria Hospital: A 5-year Retrospective Cohort Study

2015-01-01

Background: Patient attrition has been a challenge in managing HIV programs in resource-limited settings. Aim: This study reviews the predictors of loss to follow-up (LTFU) in our hospital and suggests the best practices for dealing with the issue. Subjects and Methods: A 5-year retrospective cohort study of 1256 HIV-infected patients. Baseline CD4 counts, age, gender, year of enrolment, and antiretroviral therapy combination regimen were considered in this study. Kaplan–Meier models were used to estimate the univariate time-to-LTFU and Cox proportional hazards models to identify the multivariate predictors of LTFU. Results: Twenty-four percent (23.9% [301/1256]) of patients were lost to follow-up. Baseline CD4 count, year of enrolment, and drug combination were significant predictors of LTFU. Patients enrolled earlier (2008/2009) were twice as likely to be LTFU compared with those enrolled later (2010–2013). Gender and age did not significantly predict LTFU nor confound other predictors. Conclusion: The program showed higher LTFU rates than most studies in Nigeria and Africa, maybe due to difficulties with the access to the hospital and possible treatment fatigue. This study recommends the provision of transportation subsidies and proactive patient follow-up with “peer-tracking” to reduce LTFU among HIV infected patients, especially in resource-limited settings.

Pernicious anemia (PA) is an autoimmune disease that causes achlorhydria or profound hypochlorhydria. We conducted a population-based study to determine whether individuals with PA are at an increased risk for community-acquired pneumonia (CAP). We performed a retrospective cohort study using The Health Improvement Network (THIN) from the UK (1993-2009). The eligible study cohort included individuals 18 years of age or older, with at least 1 year of THIN follow-up. The exposed group consisted of individuals with a diagnosis code for PA. The unexposed group consisted of individuals without a diagnosis of PA and was frequency matched with the exposed group with respect to age, sex, and practice site. Cox regression analysis was used to determine the hazard ratio with the 95% confidence interval for CAP associated with PA, accounting for a comprehensive list of potential confounders. The study included 13,605 individuals with PA and 50,586 non-PA individuals. The crude incidence rate of CAP was 9.4/1000 person-years for those with PA, versus 6.4/1000 person-years for those without PA. The multivariable adjusted hazard ratio for CAP associated with PA was 1.18 (95% confidence interval 1.08-1.29). In this large population-based cohort study, individuals with PA and presumed chronic achlorhydria were at an increased risk for CAP.

Factors associated with one-year mortality after recovery from critical illness are not well understood. Clinicians generally lack information regarding post-hospital discharge outcomes of patients from the intensive care unit, which may be important when counseling patients and families. We sought to determine which factors among patients who survived for at least 30 days post-ICU admission are associated with one-year mortality. Single-center, longitudinal retrospective cohort study of all ICU patients admitted to a tertiary-care academic medical center from 2001-2012 who survived ≥30 days from ICU admission. Cox's proportional hazards model was used to identify the variables that are associated with one-year mortality. The primary outcome was one-year mortality. 32,420 patients met the inclusion criteria and were included in the study. Among patients who survived to ≥30 days, 28,583 (88.2%) survived for greater than one year, whereas 3,837 (11.8%) did not. Variables associated with decreased one-year survival include: increased age, malignancy, number of hospital admissions within the prior year, duration of mechanical ventilation and vasoactive agent use, sepsis, history of congestive heart failure, end-stage renal disease, cirrhosis, chronic obstructive pulmonary disease, and the need for renal replacement therapy. Numerous effect modifications between these factors were found. Among survivors of critical illness, a significant number survive less than one year. More research is needed to help clinicians accurately identify those patients who, despite surviving their acute illness, are likely to suffer one-year mortality, and thereby to improve the quality of the decisions and care that impact this outcome.

To assess the existing situation relating to investments made by development partners in the health sector in Pakistan. This was a retrospective study completed over a period of 6 months in which financial data for the year July 2004 to June 2005 was collected. A uniform matrix was circulated to all the stakeholders in public sector and international donors who had a stake in health. Details of expenses in health over the last 5 years and plans for the next 10 years were requested. Initial draft was shared with all concerned for concurrence before finalization. Simple analysis was carried out on the collected data. About 80% of the financial resources in the public sector are provided by the Government of Pakistan with non-development and recurring expenses predominating in these allocations. The study shows that Pakistan's per capita spending on health by the public sector is Rs 375.00 (US$ 6.4) out of which Rs 80 (US$ 1.3) is being contributed by the partners. Majority of the partners contributions are used for development projects. The study concludes that an additional amount of about 250 billion rupees per year (keeping in mind the recommendations of Commission for Macroeconomics and Health) are required by the health sector. This can only be achieved by allocating at least 50% more for health every year for next 10 years in order to catch up on the lagging targets set by Millennium Development Goals for Pakistan.

Ballet dancers are high-performance athletes who are particularly susceptible to a wide variety of musculoskeletal injuries. However, they are relatively understudied, and data on their injury rates are lacking. This retrospective study features the largest aggregate data on professional ballet dancers to date and aims to identify the most common diagnoses and areas of injury in this unique population to better direct preventative and clinical practices. The study encompassed a 10-year period from January 2000 to December 2010 of dancers from a single company. Data regarding the dancers' age, gender, location of injury, and diagnosis were collected from workers' compensation claims, company records, and medical records maintained by the treating doctors. These were analyzed to determine metrics on injury incidence, frequency, and diagnosis. Over the 10-year span, 574 injuries occurred. There were approximately 52 dancers per year for a total of 153 who danced at least one complete season during the study period. The average age was 27, and 53% were female. Given turnover with retirement and replacements, the total number of dancer-years was 520, indicating an injury incidence per annum of 1.10 (574 injuries per 520 dancer-years). The most common locations of injury were foot and ankle and the lumbar spine, with the three most common diagnoses making up greater than a third (37%) of the total. As the current largest study in professional ballet, the findings set the benchmark metrics for musculoskeletal injury to the foot, ankle, and lumbar spine sites. Future studies should aim to identify injury risk factors and modalities for prevention of these injuries.

2006-01-01

The Composipost endodontic post, made of stretched aligned carbon fibers embedded in an epoxy-resin matrix, has since the beginning of the nineties been widely used for the restoration of endodontically treated teeth. The aim of this retrospective study was to evaluate the treatment outcome of the Composipost system up to 7 years. In a study published 1998, 236 patients treated during 1992-93 by seven Swedish general dental private practitioners were studied. Five of the former seven private practitionersi consented to participate in this follow up of that study. Thus the material was reduced to 138 patients. Thirty-nine of these were excluded due to insufficient data. For the remaining 99 patients, data were collected from dental records. All patients were offered a clinical examination but only 25 accepted. Data were collected from dental records for the remaining 74 patients. The mean follow up time was 6,7 years with a range from 1 month to 10 years (median 7.6 years, SD 2.5 years), (five teeth were extracted during the previous study). The outcome was considered successful if the post and core was in situ and showed no clinical or radiographic signs of technical failures. Sixty-four teeth (65%) restored with the Composipost system were successful after a mean time of 6.7 years. Thirty-two teeth were extracted due to fractures, periapical lesions and periodontitis. Dislodgment of post was observed in three cases. In conclusion, within the limitations of this study, after a mean time of 6.7 years, the Composipost restored teeth had shorter survival times than those of previously documented cast posts.

To determine participant knowledge and reporting of hypoglycaemia in the non-interventional Hypoglycaemia Assessment Tool (HAT) study. HAT was conducted in 24 countries over a 6-month retrospective/4-week prospective period in 27 585 adults with Type 1 or insulin-treated Type 2 diabetes mellitus. Participants recorded whether hypoglycaemia was based on blood glucose levels, symptoms or both. Hypoglycaemia rates were consistently higher in the prospective compared with the retrospective period. Most respondents (96.8% Type 1 diabetes; 85.6% Type 2 diabetes) knew the American Diabetes Association/European Association for the Study of Diabetes hypoglycaemia definition, but there were regional differences in the use of blood glucose measurements and/or symptoms to define events. Confirmed symptomatic hypoglycaemia rates were highest in Northern Europe/Canada for Type 1 diabetes (63.9 events/year) and in Eastern Europe for Type 2 diabetes (19.4 events/year), and lowest in South East Asia (Type 1 diabetes: 6.0 events/year; Type 2 diabetes: 3.2 events/year). Unconfirmed symptomatic hypoglycaemia rates were highest in Eastern Europe for Type 1 diabetes (5.6 events/year) and South East Asia for Type 2 diabetes (4.7 events/year), and lowest for both in Russia (Type 1 diabetes: 2.1 events/year; Type 2 diabetes: 0.4 events/year). Participants in Latin America reported the highest rates of severe hypoglycaemia (Type 1 diabetes: 10.8 events/year; Type 2 diabetes 3.7 events/year) and severe hypoglycaemia requiring hospitalization (Type 1 diabetes: 0.56 events/year; Type 2 diabetes: 0.44 events/year). The lowest rates of severe hypoglycaemia were reported in South East Asia (Type 1 diabetes: 2.0 events/year) and Northern Europe/Canada (Type 2 diabetes: 1.3 events/year), and the lowest rates of severe hypoglycaemia requiring hospitalization were in Russia (Type 1 diabetes: 0.15 events/year; Type 2 diabetes: 0.09 events/year). The blood glucose cut-off used to define hypoglycaemia varied between regions (Type 1 diabetes: 3.1-3.6 mmol/l; Type 2 diabetes: 3.5-3.8 mmol/l). Under-reporting of hypoglycaemia rates in retrospective recall and regional variations in participant definitions of hypoglycaemia may contribute to the global differences in reported rates. Discrepancies between participant definitions and guidelines may highlight a need to redefine hypoglycaemia criteria. This article is protected by copyright. All rights reserved.

Fleming, Jane; Matthews, Fiona E; Brayne, Carol

2008-01-01

Background The "oldest old" are now the fastest growing section of most western populations, yet there are scarcely any data concerning even the common problem of falls amongst the very old. Prospective data collection is encouraged as the most reliable method for researching older people's falls, though in clinical practice guidelines advise taking a history of any recalled falls. This study set out to inform service planning by describing the epidemiology of falls in advanced old age using both retrospectively and prospectively collected falls data. Methods Design: Re-survey of over-90-year-olds in a longitudinal cohort study – cross-sectional interview and intensive 12-month follow-up. Participants and setting: 90 women and 20 men participating in a population-based cohort (aged 91–105 years, in care-homes and community-dwelling) recruited from representative general practices in Cambridge, UK Measurements: Prospective falls data were collected using fall calendars and telephone follow-up for one year after cross-sectional survey including fall history. Results 58% were reported to have fallen at least once in the previous year and 60% in the 1-year follow-up. The proportion reported to have fallen more than once was lower using retrospective recall of the past year than prospective reports gathered the following year (34% versus 45%), as were fall rates (1.6 and 2.8 falls/person-year respectively). Repeated falls in the past year were more highly predictive of falls during the following year – IRR 4.7, 95% CI 2.6–8.7 – than just one – IRR 3.6, 95% CI 2.0–6.3, using negative binomial regression. Only 1/5 reportedly did not fall during either the year before or after interview. Conclusion Fall rates in this representative sample of over-90-year-olds are even higher than previous reports from octogenarians. Recalled falls last year, particularly repeated falls, strongly predicted falls during follow-up. Similar proportions of people who fell were reported by retrospective and prospective methods covering two consecutive years. Recall methods may underestimate numbers of repeated falls and the extent of recurrent falling. Professionals caring for people of advanced age can easily ask routinely whether someone has fallen at all, or more than once, in the past year to identify those at high risk of subsequent falls.

2002-09-01

In these prospective and retrospective studies the authors evaluated trauma-induced myelopathy in patients with ossification of the posterior longitudinal ligament (OPLL) to determine the effectiveness of preventive surgery for this disease. The authors studied 552 patients with cervical OPLL, including 184 with myelopathy at the time of initial consultation and 368 patients without myelopathy at that time. In the former group of 184 patients retrospective analysis was performed using an interview survey to ascertain the relationship between onset of myelopathy and trauma. In the latter group of 368 patients prospective examination was conducted by assessing radiographic findings and noting changes in clinical symptoms apparent during regular physical examination. The follow-up period ranged from 10 to 32 years (mean 19.6 years). In the retrospective investigation, 24 patients (13%) identified cervical trauma as the trigger of their myelopathy. In the prospective investigation, 70% of patients did not develop myelopathy over a follow-up period greater than 20 years (determined using the Kaplan-Meier method). Of the 368 patients without myelopathy at the time of initial consultation, only six patients (2%) subsequently developed trauma-induced myelopathy. Types of ossification in patients who developed trauma-induced myelopathy were primarily a mixed type. All patients in whom stenosis affected 60% or greater of the spinal canal developed myelopathy regardless of a history of trauma. Preventive surgery prior to onset of myelopathy is unnecessary in most patients with OPLL.

We conducted a retrospective analysis to investigate treatment results and prognostic factors of pediatric neuroblastoma patients. This retrospective study was carried out analyzing the medical records of patients with the pathological diagnosis of neuroblastoma seen at South Egypt Cancer Institute, Assiut University during the period from January 2001 and January 2010. After induction chemotherapy, response according to international neuoblastoma response criteria was assessed. Radiotherapy to patients with residual primary tumor was applied. Overall and event free survival (OAS and EFS) rates were estimated using Graphed prism program. The Log-rank test was used to examine differences in OAS and EFS rates. Cox-regression multivariate analysis was done to determine the independent prognostic factors affecting survival rates. Fifty three cases were analyzed. The median follow-up duration was 32 months and ranged from 2 to 84 months. The 3-year OAS and EFS rates were 39.4% and 29.3% respectively. Poor prognostic factors included age >1 year of age, N-MYC amplification, and high risk group. The majority of patients (68%) presented in high risk group, where treatment outcome was poor, as only 21% of patients survived for 3 year. Multivariate analysis confirmed only the association between survival and risk group. However, in univariate analysis, local radiation therapy resulted in significant survival improvement. Therefore, radiotherapy should be given to patients with residual tumor evident after induction chemotherapy and surgery. Future attempts to improve OAS in high risk group patients with aggressive chemotherapy and bone marrow transplantation should be considered.

Patients frequently report functional and subjective improvement following total hip (THA) and knee arthroplasty (TKA), but these improvements do not correlate with decreased body weight at 1- and 2-year follow-up. The purpose of this retrospective study was to investigate changes in body weight following THA and TKA at longer follow-up than the 1- to 2-year follow-up frequently reported in the literature. A retrospective review of patients undergoing THA and TKA, as well as other commonly performed lower extremity orthopedic surgeries, was completed for January 2002 to October 2011 at a single tertiary care facility. Adults who underwent a single lower extremity orthopedic procedure during that time period were included in the study. Patients undergoing THA and TKA were analyzed for clinically and statistically significant weight changes at 1- and minimum 2-year follow-up. At a mean follow-up of 4.82 years, TKA resulted in a statistically significant decrease in mean body weight (1.47 kg; P=.0109). This finding was unique to TKA. The proportion of individuals who experienced clinically significant weight loss between the 1- and minimum 2-year follow-up was higher than the proportion of individuals who gained clinically significant weight over the same time period following THA and TKA. The results of this study suggest that clinically significant weight loss may continue for several years beyond the 1- and 2-year follow-up that is frequently reported in the literature.

Introduction Children with myelomeningocele (MMC) are usually subjected to multiple surgeries. However, the number and type of surgeries are not the same in every patient with MMC over time. This report summarizes the surgical interventions in a cohort of several ages. Materials and methods Data on all of the patients with MMC, aged from 1 year and 10 months to 21 years and 11 months, were retrospectively reviewed at the Dona Estefânia Hospital in Lisbon, Portugal. Data were collected by chart review and individual interviews. The factors analyzed were demographics, ambulatory status, neurological level of involvement, shunt status, Arnold–Chiari malformation type II, surgical history, and occurrence of fracture. The surgical interventions were categorized as neurosurgical, orthopedic, urinary, ulcer repair and others. Results A total of 84 alive were eligible and enrolled. The average age was 14 years and six months. A total of 59 patients received shunts (all but one ventriculoperitoneal). In the study group, the 84 patients required 663 surgeries. Neurosurgical interventions were the most frequent surgical procedure and predominated during the first 2 years of life. Surgical interventions related to shunts were the most common neurosurgical interventions. Orthopedic surgeries were more frequent in the age group 6–12 years. Urological surgeries were done mainly after 6 years of age. Surgical repair of pressure ulcers was more common after 12 years of age. Conclusions Our study brings to light the complexity of this condition, with multiple surgeries among patients with MMC. PMID:25029586

Abstract This retrospective study compared efficacy and safety of fludarabine combined with intermediate-dose cytarabine (FA regimen) versus high-dose cytarabine (HiDAC regimen) as consolidation therapy in acute myeloid leukemia (AML) patients who achieved complete remission. Disease-free survival (DFS) and overall survival (OS) based on age (≥60, <60 years) and cytogenetics were evaluated from data between January 2005 and March 2013. Total 82 patients (FA, n = 45; HiDAC, n = 37; 14–65 years) were evaluated. Five-year DFS was 32.0% and 36.2% for FA and HiDAC groups, respectively (P = 0.729), and 5-year OS was 39.5% and 47.8% (P = 0.568), respectively. Among older patients (≥60 years), 3-year DFS was 26.0% for FA group and 12.5% for HiDAC group (P = 0.032), and 3-year OS was 34.6% and 12.5%, respectively (P = 0.026). In FA group, hematological toxicities were significantly lower. FA regimen was as effective as HiDAC regimen in patients with good/intermediate cytogenetics and significantly improved DFS and OS in older patients. PMID:25501050

Nontuberculous mycobacterial pulmonary disease (NTM-PD) has become an emerging infectious disease and is responsible for more deaths than tuberculosis in industrialized countries. NTM-PD mortality remains high in some series reportedly ranging from 25% to 40% at five years and often due to unfavorable evolution of NTM-PD despite established treatment. The purpose of our study was to search for early factors that could predict the favorable or unfavorable evolution of NTM-PD at the first year of treatment. In this retrospective and multicenter study, we selected 119 patients based on clinical, radiological and microbiological data from 2002 to 2012 from three French university hospitals (Guadeloupe, Martinique, Montpellier) with definite (meeting the criteria of the American Thoracic Society and the Infectious Disease Society of America in 2007; ATS/IDSA) or probable (one positive sputum culture) NTM-PD. We compared two patient groups: those who improved at one year (clinical symptoms, radiological lesions and microbiology data) and those who did not improve at one year. The data were analyzed for all patients as well as for subgroups by gender, HIV-positive patients, and Mycobacterium avium complex (MAC) infection. The average patient age was 50 years ± 19.4; 58% had respiratory comorbidities, 24% were HIV positive and 19% had cystic fibrosis. Coughing concerned 66% of patients and bronchiectasis concerned 45%. The most frequently isolated NTM were MAC (46%). 57% (n = 68) of patients met the ATS criteria and improved status concerned 38.6% (n = 46). The improvement factors at one year of NTM-PD were associated with the duration of ethambutol treatment: (Odds ratio adjusted [ORa]: 2.24, 95% Confidence interval [CI]; 2.11-3.41), HIV-positive status: (ORa: 3.23, 95% CI; 1.27-8.45), and male gender: (ORa: 2.34, 95% CI; 1.26-8.16). For the group with NTM-PD due to MAC, improvement was associated with the duration of macrolide treatment (ORa: 3.27, 95% CI; 1.88-7.30) and an age <50 years (ORa: 1.88, 95% CI; 1.55-8.50). In this retrospective multicenter study, improvement at one year in patients with definite or probable NTM-PD was associated with the duration of ethambutol treatment, HIV-positive status and male gender. For the group of patients infected with MAC, improvement was associated with the duration of macrolide treatment and an age <50 years. Identifying predictors of improvement at one year of NTM-PD is expected to optimize the management of the disease in its early stages.

Studies on children with hyperhidrosis are sparse. This retrospective study presents clinical data and quality of life, along with treatment effect and safety of botulinum toxin (BTX). Case reports from 366 children were included to capture the medical history of hyperhidrosis. The total median score of the Dermatology Life Quality Index before treatment was 11 for children aged 16-17 years and 12 for children younger than 16 years. The children described physical, psychosocial and consequence-related symptoms. More than 70% had multifocal hyperhidrosis. BTX-A and/or BTX-B were given to 323 children, 193 of whom received repeated treatments. The highest score in a 5-grade scale concerning treatment effect was reported by 176/193 children, i.e. their "sweating disappeared completely". No severe adverse events occurred. Focal and multifocal hyperhidrosis in children reduces quality of life considerably. Treatment with BTX-A and/or BTX-B has been performed with success.

The purpose of this study was to examine institutional trends in the volume of clavicle fractures in children and adolescents. Medical records were retrospectively reviewed to identify patients aged 10-18 years treated for a clavicle fracture between 1999 and 2011 at a single tertiary-care pediatric hospital. There were significant increases in the number of clavicle fractures seen annually, of midshaft clavicle fractures, and of midshaft clavicle fractures treated operatively. The percentage of midshaft clavicle fractures treated with fixation also increased significantly. The volumes of clavicle fractures and midshaft clavicle fractures treated operatively appear to be increasing. Despite a lack of evidence-based support, the frequency of fixation of midshaft clavicle fractures appear to be increasing in the pediatric population.

Carcinoma vulva is a rare disease accounting for 1.3% of all gynaecological malignancies. The present study is a 10-year retrospective review of our experience of the surgical options, morbidity, failure pattern, and survival for invasive carcinoma vulva. Retrospective analysis of case records of 39 patients who underwent surgery for invasive vulval cancer between 2004 and 2013 in the Department of Surgical Oncology at the Government Royapettah Hospital, Chennai. The median age was 55 years. Radical vulvectomy was the preferred surgery. 31 patients underwent lymphadenectomy. Seroma formation and groin skin necrosis were the most common postoperative complications. With a median follow-up of 32 months, 8 patients (20.5%) developed recurrence (systemic = 1, regional = 4, and local = 3). The estimated 5-year disease-free survival (DFS) was 65.4% and the overall survival (OS) was 85.1%. On univariate analysis, stage and lymph node involvement significantly affected OS. Nodal involvement with extracapsular spread (ECS) significantly affected both DFS and OS. The treatment of carcinoma vulva should be individualized with multidisciplinary cooperation. The paucity of data, especially from India, necessitates the need for more studies, preferably multicentric, keeping in mind the low prevalence.

Ewing tumors remain of poor prognosis, with 5-year overall survival of 55% to 65% in localized patients and not exceeding 25% in primarily metastatic disease. Several reports, mainly in children, have reported that some patients with poor-risk Ewing tumors may benefit from high-dose chemotherapy (HDCT) with autologous stem cell rescue. This retrospective study analyzed 46 patients treated in our institution between 1987 and 2000 for localized or primary metastatic Ewing tumors by HDCT followed by stem cell rescue. Median follow up was 7.1 years. Median age was 21 years (range, 15-46 years). Twenty-two percent of patients had metastases at diagnosis. The tumor site was axial in 56% of patients. Median tumor size was 9.5 cm. The treatment regimen consisted of induction chemotherapy, local treatment, maintenance chemotherapy, and consolidation HDCT based on alkylating agents. No toxic death was observed in the intensive therapy phase. Five-year overall survival and progression-free survival were 63 +/- 7.7% and 47 +/- 7.6%, respectively. Pejorative prognostic factors in this population were metastases at diagnosis (5-year overall survival 34% vs.71%, P = 0.017) and poor pathologic response (5-year overall survival 44% vs.77%, P = 0.03). This retrospective study shows a high long-term survival rate with high-dose chemotherapy in adults.

Background Rabies is a fatal zoonotic disease that has been known in Ethiopia for centuries in society as “Mad Dog Disease”. It is an important disease with veterinary and public health significance in the North western zone of Tigray where previous studies have not been conducted. Frequent occurrence of outbreaks in the area led the researchers to carry out a four year retrospective study to estimate the incidence of human rabies exposure in Northwestern Tigray, Ethiopia. Methodology A referent study was conducted on human rabies exposure cases recorded from 2012 to 2015 at Suhul hospital, Shire Endaselase, Northwestern Tigray, Ethiopia. Exposure cases included in this research constituted victims bitten by unprovoked dogs and who received post exposure prophylaxis (PEP) at the hospital. Two thousand one hundred eighty human rabies exposure cases retrieved from the rabies case database were included in this study. Principal findings The majority of the exposed cases were males (1363/2180, 63%). Age wise, the most exposed age group was ≥15 years in all the study years: 166 (58%), 335 (65%), 492 (66%) and 394 (63%) in 2012, 2013, 2014 and 2015, respectively. Similarly, exposure cases for human rabies increased with age in both males and females across the study years. The incidence of human rabies exposure cases calculated per 100,000 populations was 35.8, 63.0, 89.8 and 73.1 in 2012, 2013, 2014 and 2015, respectively. Binary logistic regression analysis revealed that being male was a risk for human rabies exposure in all the study years. Conclusion The study discovered the highest annual human rabies exposure incidence in Ethiopia. This suggests an urgent need for synergistic efforts of human and animal health sectors to implement prevention and control strategies in this area. PMID:28060935

Bone metastases are a frequent complication of advanced oncologic disease. Pain associated to bone metastasis is a major cause of morbidity in cancer patients, especially in elderly. The aim of this multicentric retrospective observational study is to evaluate the efficacy of different schedules of radiation therapy in elderly patients in terms of pain relief. 206 patients over the age of 60 were enrolled in 1 year time for a multicentre retrospective observational study. Patients were treated with palliative purposes for painful bone metastases. Pain intensity difference (PID) was found in 72% of patients. Reported PID was statistically significant for p < 0.01. Pain intensity measured by a point numeric rating scale was statistically significant reduced for p < 0.05 by one-fraction regimen compared to other two regimens. In recent years, numerous studies have evaluated the most appropriate regimen of fractionation in individual cases, despite this, a consensus about the best schedule is still debated. On our analysis, single-fractionation scheme (8 Gy) confirmed to be statistical significant effective in providing pain reduction due to bone metastases. Radiation therapy provides significant pain relief of symptomatic bone metastases, but appropriate radiotherapy scheduled is needed in order to get significant response to treatment. Multidisciplinary approach is warranted to value the balance between the therapeutic objectives and the patient quality of life.

PURPOSE The aim of this retrospective study is to analyze the relationship between local factors and survival rate of dental implant which had been installed and restored in Seoul Veterans Hospital dental center for past 10 years. And when the relationship is found out, it could be helpful to predict the prognosis of dental implants. MATERIALS AND METHODS A retrospective study of patients receiving root-shaped screw-type dental implants placed from January 2000 to December 2009 was conducted. 6385 implants were placed in 3755 patients. The following data were collected from the dental records and radiographs: patient's age, gender, implant type and surface, length, diameter, location of implant placement, bone quality, prosthesis type. The correlations between these data and survival rate were analyzed. Statistical analysis was performed with the use of Kaplan-Meier analysis, Chi-square test and odds ratio. RESULTS In all, 6385 implants were placed in 3755 patients (3120 male, 635 female; mean age 65 ± 10.58 years). 108 implants failed and the cumulative survival rate was 96.33%. There were significant differences in age, implant type and surface, length, location and prosthesis type (P<.05). No significant differences were found in relation to the following factors: gender, diameter and bone quality (P>.05). CONCLUSION Related factors such as age, implant type, length, location and prosthesis type had a significant effect on the implant survival. PMID:22259704

Abstract Early language delay has often been associated with atypical language/literacy development. Neuroimaging studies further indicate functional disruptions during language and print processing in school-age children with a retrospective report of early language delay. Behavioral data of 114 5-year-olds with a retrospective report of early language delay in infancy (N = 34) and those without (N = 80) and with a familial risk for dyslexia and those without are presented. Behaviorally, children with a retrospective report of early language delay exhibited reduced performance in language/reading-related measures. A voxel-based morphometry analysis in a subset (N = 46) demonstrated an association between reduced gray matter volume and early language delay in left-hemispheric middle temporal, occipital, and frontal regions. Alterations in middle temporal cortex in children with a retrospective report of early language delay were observed regardless of familial risk for dyslexia. Additionally, while children with isolated familial risk for dyslexia showed gray matter reductions in temporoparietal and occipitotemporal regions, these effects were most profound in children with both risk factors. An interaction effect of early language delay and familial risk was revealed in temporoparietal, occipital, and frontal cortex. Our findings support a cumulative effect of early behavioral and genetic risk factors on brain development and may ultimately inform diagnosis/treatment. PMID:26585334

Objective To directly compare the performance and externally validate the three most studied prediction tools for osteoporotic fractures—QFracture, FRAX, and Garvan—using data from electronic health records. Design Retrospective cohort study. Setting Payer provider healthcare organisation in Israel. Participants 1 054 815 members aged 50 to 90 years for comparison between tools and cohorts of different age ranges, corresponding to those in each tools’ development study, for tool specific external validation. Main outcome measure First diagnosis of a major osteoporotic fracture (for QFracture and FRAX tools) and hip fractures (for all three tools) recorded in electronic health records from 2010 to 2014. Observed fracture rates were compared to probabilities predicted retrospectively as of 2010. Results The observed five year hip fracture rate was 2.7% and the rate for major osteoporotic fractures was 7.7%. The areas under the receiver operating curve (AUC) for hip fracture prediction were 82.7% for QFracture, 81.5% for FRAX, and 77.8% for Garvan. For major osteoporotic fractures, AUCs were 71.2% for QFracture and 71.4% for FRAX. All the tools underestimated the fracture risk, but the average observed to predicted ratios and the calibration slopes of FRAX were closest to 1. Tool specific validation analyses yielded hip fracture prediction AUCs of 88.0% for QFracture (among those aged 30-100 years), 81.5% for FRAX (50-90 years), and 71.2% for Garvan (60-95 years). Conclusions Both QFracture and FRAX had high discriminatory power for hip fracture prediction, with QFracture performing slightly better. This performance gap was more pronounced in previous studies, likely because of broader age inclusion criteria for QFracture validations. The simpler FRAX performed almost as well as QFracture for hip fracture prediction, and may have advantages if some of the input data required for QFracture are not available. However, both tools require calibration before implementation. PMID:28104610

Stroke occurring during pregnancy and the postnatal period is a rare but potentially catastrophic event. The aim of this study was to examine the incidence and outcomes of pregnancies complicated by maternal stroke in a single centre. This is a prospective study of over 35,000 consecutive pregnancies over a four-year period at the National Maternity Hospital in Dublin from 2004 to 2008; in addition we also retrospectively examined all cases of maternal mortality at our institution over a 50-year period from 1959 to 2009. We prospectively identified eight cases of strokes complicating pregnancy and the postnatal period giving an overall incidence of 22.34 per 100,000 pregnancies or 24.74 per 100,000 deliveries. There were no stroke-related mortalities during that time. Retrospective analysis of maternal mortality revealed 102 maternal deaths over a 50-year period, 19 (18.6%) of which were due to cerebrovascular accidents. In conclusion, strokes complicating pregnancy and the puerperium remain a rare event and though there appears to be evidence that the incidence is increasing, the associated maternal mortality appears to be falling.

A fall in hospital deaths in dementia has been interpreted as indicating an improvement in end-of-life care. Whether other indicators of quality of end-of-life care, such as emergency department (ED) attendance, show a similar trend is unclear. Retrospective cohort study using electronic medical records from a large mental health care provider, linked to national mortality and hospital use data (2008-2013). Of 4867 patients, 78.6% (3824) had at least one ED attendance during their last year of life (mean 2.13, standard deviation 2.34, range 0-54). ED attendance increased over the time period (incidence rate ratio 1.62, 95% confidence interval 1.46-1.80 for 2012-2013 compared with 2008-2009). ED attendance in the last year of life for people with dementia is common and is increasing. Policy makers must pay attention to a broader range of indicators of poor end-of-life care alongside the place of death. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

To quantify the Lower Extremity Amputations (LEA) incidence in population with and without diabetes mellitus (DM). Retrospective cohort study of all the LEA carried out during 2001-2006 in area 3 of Madrid, from the codification of the reports of discharge reports. 310 LEA were carried out. The age-ajusted LEA incidence for any reason was 19,2/10(5) inhabitants per year (27,2 y 11,2 for men and women respectively). 261 were not-traumatic and non-tumoural (NTT) LEA, 76% were associated with DM and the incidence was 191/10(5) people with DM per year (95% confidence interval [CI(95)] 122-299) and 4,4/10(5) for people without DM per year (CI(95) 7-23), with a risk ratio of 44 (CI(95) 23-73). The LEA rates in population with o without diabetes are higher than the previously communicated in Madrid. It would appear convenient to design strategies to reduce the LEA rates.

Roberts, Ralph A

2005-01-01

This study quantifies the changes in bone height noted in the body of the edentulous mandibles when the load of the complete denture is born by an RA Ramus Frame Implant (Pacific Implant, Rio Dell, Calif). Eighty-three patients with implants were followed for 3 to 24 years. Pre- and postoperative panoramic films were taken and again at each succeeding 5-year follow-up. The results of the bone changes were gathered retrospectively and calculated. The data revealed a significant increase in bone height from 4.413 to 13 mm and statistically significant P values of <.0003 were determined. The growth of bone appears to be influenced by the design of the posterior feet, dominant chewing side, and a range of extreme atrophy from 5.9 mm to 15 mm. Also, the previously lost anatomical structures appear to repair, such as the luman of the mental foramen and the superior wall over the inferior alveolar canal. All mandibles were loaded postoperatively with an appliance having cutting bars and porcelain teeth or just porcelain teeth in both appliances.

A retrospective, longitudinal study examined changes in participation in fitness-related activities and hospital claims over 5 years amongst members of an incentivized health promotion program offered by a private health insurer. A 3-year retrospective observational analysis measuring gym visits and participation in documented fitness-related activities, probability of hospital admission, and associated costs of admission. A South African private health plan, Discovery Health and the Vitality health promotion program. 304,054 adult members of the Discovery medical plan, 192,467 of whom registered for the health promotion program and 111,587 members who were not on the program. Members were incentivised for fitness-related activities on the basis of the frequency of gym visits. Changes in electronically documented gym visits and registered participation in fitness-related activities over 3 years and measures of association between changes in participation (years 1-3) and subsequent probability and costs of hospital admission (years 4-5). Hospital admissions and associated costs are based on claims extracted from the health insurer database. The probability of a claim modeled by using linear logistic regression and costs of claims examined by using general linear models. Propensity scores were estimated and included age, gender, registration for chronic disease benefits, plan type, and the presence of a claim during the transition period, and these were used as covariates in the final model. There was a significant decrease in the prevalence of inactive members (76% to 68%) over 5 years. Members who remained highly active (years 1-3) had a lower probability (p < .05) of hospital admission in years 4 to 5 (20.7%) compared with those who remained inactive (22.2%). The odds of admission were 13% lower for two additional gym visits per week (odds ratio, .87; 95% confidence interval [CI], .801-.949). We observed an increase in fitness-related activities over time amongst members of this incentive-based health promotion program, which was associated with a lower probability of hospital admission and lower hospital costs in the subsequent 2 years.

Zhou, Jinhong; Shan, Guoping; Chen, Yiwen

2016-08-01

Our objective was to perform a meta-analysis examining the effectiveness of lymphadenectomy in patients with ovarian cancer. PubMed and CENTRAL databases were searched on 15 November 2015 using the terms 'lymphadenectomy', 'ovarian cancer', 'dissection', 'para-aortic', 'pelvic' and survival. Prospective and retrospective studies comparing the outcomes of surgery with or without lymphadenectomy were included. Outcomes were 5-year overall survival, progression-free survival and recurrence rate. Of the 556 studies identified, 3 randomized controlled trials and 11 retrospective studies were included. Lymphadenectomy was associated with greater 5-year overall survival than no lymphadenectomy (pooled odds ratio = 1.58, 95% confidence interval: 1.41-1.77, p < 0.001). There was no difference in progression-free survival between the groups (pooled overall survival = 1.62, 95% confidence interval: 0.82-3.21, p = 0.168). Lymphadenectomy was associated with greater progression-free survival in randomized clinical trials (pooled overall survival = 1.57, 95% confidence interval: 1.11-2.21, p = 0.010), but not in retrospective studies. Lymphadenectomy was associated with a significantly lower recurrence rate (pooled overall survival = 0.51, 95% confidence interval: 0.30-0.85, p = 0.011). Lymphadenectomy was associated with greater 5-year overall survival in patients with both early and advanced stage cancer, but was associated with greater progression-free survival and lower recurrence rate only in patients with advanced stage cancer. Lymphadenectomy is associated with greater 5-year overall survival in patients with early and advanced stage ovarian cancer, but an effect on progression-free survival and recurrence rate was only found in patients with advanced stage ovarian cancer. © The Author 2016.

Clostridium difficile is an emerging cause of healthcare associated infections. In nine hospitals of an Italian Local Health Authority the episodes of C. difficile infection (CDI) were identified using the data registered by the centralized Laboratory Information System, from 2010 to 2015. CDI incidence (positive patients for A and/or B toxins per patients-days) was analysed per year, hospital, and ward. A number of cases approximately equivalent to the mean of identified cases per year were studied retrospectively to highlight the risk factors associated to CDI and their severity. Nine hundred and forty-two patients affected by CDI were identified. The overall incidence was 3.7/10,000 patients-days, with a stable trend across the six years and the highest rates observed in smaller and outlying hospitals (up to 17.8/10,000), where the admitted patients were older and the wards with the highest incidences (long-term-care: 7.6/10,000, general medicine: 5.7/10,000) were more represented. The mean age of patients in each hospital was correlated with CDI rates. Of the 101 cases selected for the retrospective study, 86.1% were healthcare associated, 10.9% community acquired; 9.1% met the criteria for recurrent case and 23.8% for severe case of CDI. The overall mortality rate was 28.7%. Comorbidity conditions occurred in 91.1%, previous exposure to antibiotics in 76.2%, and proton pump inhibitors in 77.2%. Recurrent and severe cases were significantly associated with renal insufficiency and creatinine levels ≥2 mg/dL. The survey based on the centralized laboratory data was useful to study CDI epidemiology in the different centres in order to identify possible weaknesses and plan control strategies, in particular the reinforcement of staff training, mainly targeted at compliance with contact precautions and hand hygiene.

The retrospective epidemiological study of Latin Americans with transfusional hemosiderosis is the first regional patient registry to gather data regarding the burden of transfusional hemosiderosis and patterns of care in these patients. Retrospective and cross-sectional data were collected on patients ≥2 years with selected chronic anemias and minimum 20 transfusions. In the 960 patients analyzed, sickle-cell disease (48·3%) and thalassemias (24·0%) were the most frequent underlying diagnoses. The registry enrolled 355 pediatric patients (187 with sickle-cell disease/94 with thalassemia). Serum ferritin was the most frequent method used to detect iron overload. Complications from transfusional hemosiderosis were reported in ~80% of patients; hepatic (65·3%), endocrine (27·5%), and cardiac (18·2%) being the most frequent. These data indicate that hemoglobinopathies and complications due to transfusional hemosiderosis are a significant clinical problem in the Latin American population with iron overload. Chelation therapy is used insufficiently and has a high rate of discontinuation.

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.

Defining reference range is an essential tool for diagnostic. Age and sexe influences on thyroid hormone levels have been already discussed. In this study, we are defining a new pediatric reference range for TSH, FT3 and FT4 for Cobas C6000 analyzer. To do so, we have taken in account 0 to 18 year old outclinic patients. During the first year of life, thyroid hormone levels change dramatically before getting stabilized around 3 years old. We also compared our results to those obtained in a Canadian large-scale prospective study (the CALIPER initiative).

2010-05-01

The aim of this retrospective cohort study was to examine whether exposure to early childhood protein-energy malnutrition (ECPEM) is related to worsened periodontal status in the permanent dentition during adolescence. A trained clinician/researcher examined the periodontal status of 96 persons aged 12-19 living in rural Haiti using WHO diagnostic criteria (Community Periodontal Index, WHO 1997). Malnutrition data of the study participants had been collected during the years 1988-1993 by a nongovernmental organization. We compared those who had been malnourished in early childhood, based on z-scores for anthropomorphic data collected during the first 5 years of life, with those who had not been malnourished, regarding mean Community Periodontal Index (CPI) score, controlling for age, sex, socioeconomic status, and smoking. Overall, 57.3% of the participants demonstrated a CPI score of 3 or greater in at least one sextant. ECPEM was independently and positively related to mean CPI score, when controlling for sex and smoking. More than half of these young Haitians demonstrated CPI scores of 3 or greater, and ECPEM was related to poorer periodontal status, as measured by CPI, in the permanent dentition.

Transforaminal endoscopic discectomy and foraminotomy is a well-described minimally invasive technique for surgically treating lumbar radiculopathy caused by a herniated disc and foraminal narrowing. To describe the technique and feasibility of transforaminal foraminoplasty for the treatment of lumbar radiculopathy in patients who have already undergone instrumented spinal fusion. Retrospective study. Hospital and ambulatory surgery center After Institutional Review Board approval, charts from 18 consecutive patients with lumbar radiculopathy and instrumented spinal fusions who underwent endoscopic procedures between 2008 and 2013 were reviewed. The average pain relief one year postoperatively was reported to be 67.0%, good results as defined by MacNab. The average preoperative VAS score was 9.14, indicated in our questionnaire as severe and constant pain. The average one year postoperative VAS score was 3.00, indicated in our questionnaire as mild and intermittent pain. This is a retrospective study and only offers one year follow-up data for patients with instrumented fusions who have undergone endoscopic spine surgery. Transforaminal endoscopic discectomy and foraminotomy could be used as a safe, yet, minimally invasive and innovative technique for the treatment of lumbar radiculopathy in the setting of previous instrumented lumbar fusion.

Sulphur mustard (SM) is an alkylating chemical warfare agent which causes acute and chronic injuries to the eyes, skin, lung and respiratory tract. We aimed to investigate the relationship between SM poisoning and Mycosis fungoides (MF) as a late consequence. In this retrospective study, the medical files of 1100 Iranian veterans confirmed to have exposure to SM agent during the Iraq-Iran war of the 1980s were reviewed. All 10 cases with MF were confirmed by clinical and histopathological examinations. The mean age of the studied subjects was 43.3 ± 9.8 (years). In comparison to MF incidence rate in Iranian general population (0.39/100 000 person-years), we found an incidence rate of 0.799/100 000 person-years for MF among those who had short-term exposure to SM. The most common sites for SM lesions were flexural and thin skin areas. The main limitation was the retrospective design. This study indicates that the risk of MF in those exposed to SM may increase over time. Therefore, their follow-up is recommended. © 2016 European Academy of Dermatology and Venereology.

Objective To determine the prospective association between retrospectively assessed physical work environment during working life and prospectively assessed sickness absence and labour market exit among older workers. Methods Using Cox regression analyses we estimated the 4-year to 6-year prospective risk of register-based long-term sickness absence (LTSA), disability pension, early retirement and unemployment from exposure to different physical work environmental factors during working life among 5076 older workers (age 49–63 at baseline) from the Copenhagen Aging and Midlife Biobank cohort. Results Very hard physical work throughout working life was a risk factor for LTSA (HR 1.66,95% CI 1.32 to 2.07), disability pension (HR 2.21,95% CI 1.04 to 4.72) and early retirement (HR 1.57,95% CI 1.13 to 2.17). Both short-term (<10 years) and long-term (≥20 years) exposures to lifting or carrying of heavy burdens predicted the risk of LTSA (HRs 1.49–1.56) and disability pension (HRs 2.26–3.29). In contrast, exposure to dust was associated with LTSA and disability pension only following 20 or more exposure years. Conclusions Retrospectively assessed hard physical work during working life and exposure to several factors in the physical work environment, especially heavy lifting, were important for labour market exit and sickness absence. This study underscores the importance of reducing physical work exposures throughout the working life course for preventing sickness absence and premature exit from the labour market. PMID:28819019

To report the visual outcome and refractive status in first 3 years of age in preterm infants suffered from laser-treated Type 1 retinopathy of prematurity (ROP): a 6-year review in Hong Kong DESIGN: Retrospective case series METHODOLOGY: Clinical records of all infants suffered from Type 1 ROP who had undergone laser therapy between 2007 and 2012 were retrospectively reviewed. Basic demographic data, serial changes of refractive error, visual acuity, severity of ROP and laser were analyzed. Correlation with myopia and astigmatism progression, body weight, height, growth and gestational age were also analyzed. Among 494 babies screened, 14 Chinese babies (26 eyes) recruited with 1:1 male-to-female ratio in this study. All eyes showed gradual progression of myopia in first 3 years of age but no significant change of astigmatism. Further correlation analysis showed no correlation with laser energy consumed, birth weight (p = 0.14), head circumference growth (p = 0.57) and body weight growth (p = 0.71). However, severity of myopia was related to the post-conceptual age when receiving laser therapy (p < 0.005), gestation age (p = 0.02) and possibly body height growth with age (p = 0.05). Myopia in early life is one of the most common ocular sequelae in Type 1 ROP survivors. Early detection of refractive error is important for prompt correction and visual rehabilitation to prevent amblyopia.

Given that there is no standard systemic treatment for children and adolescents with plaque psoriasis, this non-interventional, multicenter, retrospective study collected data on the efficacy and safety of long-term treatment with fumaric acid esters (FAEs) in this particular patient group. In patients younger than 18 years of age at the start of FAE treatment, data on efficacy and safety was retrospectively collected for at least 36 months. Data from 127 patients (aged 6-17 years) was collected for treatment durations of up to 60 months. Physician's Global Assessment, Psoriasis Area and Severity Index, and Body Surface Area showed marked improvement in the first six months. After 36 months, these parameters had, on average, improved by up to two-thirds of baseline values. Thirty-seven patients experienced at least one adverse event (AE), which was FAE-related in 36 individuals. Three AEs (proteinuria (one case), flushing (two cases)) persisted during the observation period while on treatment. Fifteen AEs led to the discontinuation of therapy; nearly all of these cases were related to gastrointestinal disorders. The KIDS FUTURE study - for the first time - included a larger population of children and adolescents with psoriasis who were treated with FAEs. The data obtained suggests that long-term FAE therapy in this patient group may be effective and safe. The results are currently being verified in an ongoing clinical study. © 2015 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Given that there are currently no clear recommendations regarding therapeutic options for rituximab refractory/relapsed follicular lymphoma patients, this study aimed to describe the real-life management of patients with refractory follicular lymphoma after systemic rituximab-containing regimens (rFL), and rFL patient characteristics. In this retrospective, national, multicentre study, descriptive analyses were mainly performed according to rituximab-containing regimen at rFL diagnosis [rituximab monotherapy (R-MONO), rituximab + chemotherapy (R-COMBO), and ongoing rituximab maintenance (R-MAINTAIN)]. The 459 analysed patients experienced rituximab-refractoriness between October 2013 and September 2015: R-MONO: 58 (13%), R-COMBO: 197 (43%), R-MAINTAIN: 204 (44%). Post-refractoriness strategies were heterogeneous: idelalisib ± rituximab (22%), without anti-lymphoma treatment (21%), rituximab-chemotherapy (21%) and stem cell transplantation (18%). Rituximab was continued in combination in 41% of cases. Chosen strategies varied according to patient age (without anti-lymphoma treatment: 28% of patients if ≥65 years vs. 12% if <65 years old; stem-cell transplantation: 4% vs. 38%), treatment line at rFL, FL International Prognostic Index score and prior treatment. This French retrospective study, the first one conducted in a large cohort of rFL patients, showed that further strategies were highly heterogeneous, depending notably on patient characteristics and previous treatment. These data are the basis for a better understanding of rFL management and for the design of clinical trials in these patients. © 2017 John Wiley & Sons Ltd.

Are scabies and impetigo “normalised”? A cross-sectional comparative study of hospitalised children in northern Australia assessing clinical recognition and treatment of skin infections

2017-01-01

Background Complications of scabies and impetigo such as glomerulonephritis and invasive bacterial infection in Australian Aboriginal children remain significant problems and the overall global burden of disease attributable to these skin infections remains high despite the availability of effective treatment. We hypothesised that one factor contributing to this high burden is that skin infection is under-recognised and hence under-treated, in settings where prevalence is high. Methods We conducted a prospective, cross-sectional study to assess the burden of scabies, impetigo, tinea and pediculosis in children admitted to two regional Australian hospitals from October 2015 to January 2016. A retrospective chart review of patients admitted in November 2014 (mid-point of the prospective data collection in the preceding year) was performed. Prevalence of documented skin infection was compared in the prospective and retrospective population to assess clinician recognition and treatment of skin infections. Results 158 patients with median age 3.6 years, 74% Aboriginal, were prospectively recruited. 77 patient records were retrospectively reviewed. Scabies (8.2% vs 0.0%, OR N/A, p = 0.006) and impetigo (49.4% vs 19.5%, OR 4.0 (95% confidence interval [CI 2.1–7.7) were more prevalent in the prospective analysis. Skin examination was only documented in 45.5% of cases in the retrospective review. Patients in the prospective analysis were more likely to be prescribed specific treatment for skin infection compared with those in the retrospective review (31.6% vs 5.2%, OR 8.5 (95% CI 2.9–24.4). Conclusions Scabies and impetigo infections are under-recognised and hence under-treated by clinicians. Improving the recognition and treatment of skin infections by clinicians is a priority to reduce the high burden of skin infection and subsequent sequelae in paediatric populations where scabies and impetigo are endemic.

Second malignancies (SM) represent one of the potential hazards of modern cancer treatment and especially of radio- and chemotherapy after surgery for breast cancer. For this reason, regional tumor registry data (1960-1975) on 1985 breast cancer patients were analyzed for SM in the retrospective part of our study. These data were compared with the prospective part of the study in which 241 patients were randomly assigned to either mastectomy or mastectomy and chemoimmunotherapy (CT + IT). In the retrospective part of the study, SM were observed in 83 cases (4.2%), 49% of which were SM of the contralateral breast. Most frequent extramammary SM were of gastrointestinal (25%), gynecologic (8%) and cerebral (5%) origin. Leukemias were found in 4% of all SM. Median time interval to SM was 5 years and 1 month. Within 5, 10 and 15 years after mastectomy 60%, 85% and 95% of SM were observed respectively. Median survival of patients with SM was 6 1/2 years. In the prospective part of the study, SM were observed in 9 cases (3.7%), 4.1% in the surgical control group and 3.4% in the adjuvant CT + IT group with a median observation time of 6 years post mastectomy. These data are compared to other current adjuvant breast trials and do not indicate as of now an increase in SM under present adjuvant therapy.

The periauricular percutaneous implantation of the Neuro-Stim System™ family of devices EAD, MFS, and BRIDGE is a procedure involving the use of a non-opiate, neuromodulation analgesic for relieving acute and chronic pain. It has been approved as a minimal-risk procedure by multiple governmental and institutional facilities. This retrospective report of findings will help quantify the incidence of clinically observed bleeding, localized dermatitis, and infections at the implantation sites of the electrode/needle arrays, dermatitis at the site of the generator, and patient syncope. A total of 1,207 devices, each producing up to 16 percutaneous punctures, for a total of 19,312 punctures were monitored for adverse effects, based on retrospective chart audits conducted at six clinical facilities over a 1-year period.

Blood transfusion services are a vital and integral part of modern healthcare services. However, the risk of transfusion transmittable infections (TTI) has been a major handicap. Therefore this study was aimed at determining the prevalence of hepatitis B, Hepatitis C and human immunodeficiency virus among blood donors. A retrospective study was conducted to collect data about the blood donors that consecutively donated blood from October 2011 to 2014. A three-year retrospective study was conducted in Mekelle Blood Bank. A data abstraction format was used to collect the socio-demographic and clinical data and the prevalence of HBV, HCV and HIV was determined. Data were analyzed using STATA version 10 analytical software. P value less than 0.05 were considered significant in all the analysis. A total of 10,728 blood donors, median (IQR) of age 30 (23-45) years and 3,750 (34.9%) males were enrolled in this study. Of the participants 407(3.79%), 143(1.33%) and 111(1.03%) blood donors were positive for HBV, HCV and HIV respectively. HBV-HIV co infections were found 10 (1.93%), followed by HBV-HCV and HIV-HCV. A significant association between sex and marital status with HBV and HIV infection was found. However, significant association of HCV were observed among sex (X 2 =33.18, P < 0.001) and occupational (X 2 = 84.33, P <0.001). Significant percentage of HBV, HCV and HIV among blood donors was observed. In order to select donor and collect safe blood risk factors exposing blood donor should be studied and community based prevalence studies on the TTI are also required.

OBJECTIVES: To investigate the recent fall in mortality from breast cancer in England and Wales, and to determine the relative contributions of improvements in treatment and earlier detection of tumours. DESIGN: Retrospective study of all women with breast cancer registered by the East Anglian cancer registry and diagnosed between 1982 and 1989. SUBJECTS: 3965 patients diagnosed 1982-5 compared with 4665 patients diagnosed 1986-9, in three age groups 0-49, 50-64, > or = 65 years, with information on stage at diagnosis and survival. MAIN OUTCOME MEASURES: Three year relative survival rates by time period, age group, and stage; relative hazard ratios for each time period and age group derived from Cox's proportional hazards model, adjusted for single year of age and stage. RESULTS: Survival improved in the later time period, although there was little stage specific improvement. The proportion of early stage tumours increased especially in the 50-64 year age group, and adjustment for stage accounted for over half of the improvement in survival in women aged under 65 years. CONCLUSION: Over half of the drop in mortality in women aged under 65 years seems to be attributable to earlier detection of tumours, which has been observed since the mid-1980s. This could have resulted from an increase in breast awareness predating the start of the breast screening programme. PMID:9056796

Staphylococcus saprophyticus is a rarely reported agent of urinary tract infection (UTI) in the pediatric population. In our retrospective 3-year study, S. saprophyticus comprised 24.5% of 106 isolates of UTIs in female adolescents 12-15 years of age who attended an emergency department. Clinicians should be aware of the high prevalence of this etiology when empirically treating UTIs in female adolescents.

1996-12-01

The objective of the Florida Trauma Triage Study was to assess the performance of state-adopted field triage criteria. The study addressed three specific age groups: pediatric (age < 15 years), adult (age 15-54 years), and geriatric (age 55+ years). Since 1990, Florida has used a uniform set of eight triage criteria, known as the trauma scorecard, for triaging adult trauma patients to state-approved trauma centers. However, only five of the criteria are recommended for use with pediatric patients. This article presents the findings regarding the performance of the scorecard when applied to a pediatric population. We used state trauma registry data linked to state hospital discharge data in a retrospective analysis of trauma patients transported by prehospital providers to any acute care hospital within nine selected Florida counties between July 1, 1991, and December 31, 1991. We used cross-table and logistic regression analysis to determine the ability of triage criteria to correctly identify patients who were retrospectively defined as major trauma. We applied the field criteria to physiologic and anatomy/mechanism of injury data contained in the trauma registry to "score" the patient as major or minor trauma. To make our retrospective determination of major or minor trauma we used the protocols developed by an expert medical panel as described by E. J. MacKenzie et al. (1990). We calculated sensitivity, specificity, and the corresponding over- and undertriage rates by comparing patient classifications (major or minor trauma) produced by the triage criteria and the retrospective algorithm. We used logistic regression to identify which triage criteria were statistically significant in predicting major trauma. Pediatric cases accounted for 9.2% of the total study population, 6.0% of all hospitalized cases, and 6.8% of all trauma deaths. Of the 1505 pediatric cases available for analysis, the triage criteria classified 269 cases as expected major trauma and 1236 cases as expected minor trauma. The retrospective algorithm classified 78 cases as expected major trauma and 1427 cases as expected minor trauma. The resulting specificity is 84.8% (15.2% overtriage), and the sensitivity is 66.7% (33.3% undertriage). Logistic regression indicated that, of the eight state-adopted field triage criteria, only the Glasgow coma score, ejection from vehicle, and penetrating injuries have a statistically significant impact on predicting major trauma in pediatric patients. Although the state-adopted trauma scorecard, applied to a pediatric population, produced acceptable overtriage, it did not produce acceptable undertriage. However, our undertriage rate is comparable to the results of other published studies on pediatric trauma. As a result of the Florida Trauma Triage Study, a new pediatric triage instrument was developed. It is currently being field-tested.

Objective Pernicious anemia (PA) is an autoimmune disease that causes achlorhydria or profound hypochlorhydria. We conducted a population-based study to determine whether individuals with PA are at increased risk for community-acquired pneumonia (CAP). Methods We performed a retrospective cohort study using The Health Improvement Network (THIN) from the United Kingdom (1993 to 2009). The eligible study cohort included individuals 18 years of age or older and with at least 1 year of THIN follow-up. The exposed group consisted of individuals with a diagnosis code for PA. The unexposed group consisted of individuals without a diagnosis of PA and was frequency matched with the exposed group with respect to age, sex, and practice site. Cox regression analysis was used to determine the hazard ratio (HR) with 95% confidence interval (CI) for CAP associated with PA, accounting for a comprehensive list of potential confounders. Results The study included 13,605 individuals with PA and 50,586 non-PA subjects. The crude incidence rate of CAP was 9.4 per 1000 person-years for those with PA, versus 6.4 per 1000 person-years for those without PA. The multivariable adjusted HR for CAP associated with PA was 1.18, 95% CI 1.08 – 1.29. Conclusions In this large population-based cohort study, individuals with PA and presumed chronic achlorhydria were at increased risk for CAP. PMID:26225868

A substantial evidence base in the peer-reviewed literature exists investigating mental illness in the military, but relatively less is documented about mental illness in veterans. This study uses provincial, administrative data to study the use of mental health services by Canadian veterans in Ontario. This was a retrospective cohort study of Canadian Armed Forces and Royal Canadian Mounted Police veterans who were released between 1990 and 2013 and resided in Ontario. Mental health-related primary care physician, psychiatrist, emergency department (ED) visits, and psychiatric hospitalisations were counted. Repeated measures were presented in 5-year intervals, stratified by age at release. The cohort included 23,818 veterans. In the first 5 years following entry into the health care system, 28.9% of veterans had ≥1 mental health-related primary care physician visit, 5.8% visited a psychiatrist at least once, and 2.4% received acute mental health services at an ED. The use of mental health services was consistent over time. Almost 8% of veterans aged 30 to 39 years saw a psychiatrist in the first 5 years after release, compared to 3.5% of veterans aged ≥50 years at release. The youngest veterans at release (<30 years) were the most frequent users of ED services for a mental health-related reason (5.1% had at least 1 ED visit). Understanding how veterans use the health care system for mental health problems is an important step to ensuring needs are met during the transition to civilian life.

To describe treatment and referral patterns and National Health Service resource use in patients with chronic pain associated with low back pain or osteoarthritis, from a Primary Care perspective. Osteoarthritis and low back pain are the two commonest debilitating causes of chronic pain, with high health and social costs, and particularly important in primary care. Understanding current practice and resource use in their management will inform health service and educational requirements and the design and optimisation of future care. Multi-centre, retrospective, descriptive study of adults (⩾18 years) with chronic pain arising from low back pain or osteoarthritis, identified through primary care records. Five general practices in Scotland, England (two), Northern Ireland and Wales. All patients with a diagnosis of low back pain or osteoarthritis made on or before 01/09/2006 who had received three or more prescriptions for pain medication were identified and a sub-sample randomly selected then consented to an in-depth review of their medical records (n=264). Data on management of chronic pain were collected retrospectively from patients' records for three years from diagnosis ('newly diagnosed' patients) or for the most recent three years ('established' patients). Patients received a wide variety of pain medications with no overall common prescribing pattern. GP visits represented the majority of the resource use and 'newly diagnosed' patients were significantly more likely to visit their GP for pain management than 'established' patients. Although 'newly diagnosed' patients had more referrals outside the GP practice, the number of visits to secondary care for pain management was similar for both groups. This retrospective study confirmed the complexity of managing these causes of chronic pain and the associated high resource use. It provides an in-depth picture of prescribing and referral patterns and of resource use.

Chronic wounds usually get trapped in the inflammatory stage of wound healing; however, aggressive debridement transforms chronic wounds to acute wounds and therefore complete healing. To investigate healing outcomes and debridement frequency in a large wound data set. Retrospective cohort study. Data collected from 525 wound care centers from June 1, 2008, through June 31, 2012, using a web-based clinical management system. Referred sample of 154 644 patients with 312 744 wounds of all causes (of an initial data set of 364 534 wounds) participated. A total of 47.1% were male. Median age was 69 years (age range, 19-112 years), with 59.2% having one wound. Eligibility criteria included age older than 18 years, receiving at least 1 debridement, and having been discharged from the system. Advanced therapeutic treatment was ineligible. Because of incomplete, questionable, or ineligible data, 57 190 wounds were not included. Most wounds were diabetic foot ulcers (19.0%), venous leg ulcers (26.1%), and pressure ulcers (16.2%). Debridement (removal of necrotic tissue and foreign bodies from the wound) at different frequencies. Wound healing (completely epithelialized with dimensions at 0 × 0 × 0 cm). A total of 70.8% of wounds healed. The median number of debridements was 2 (range, 1-138). Frequent debridement healed more wounds in a shorter time (P <  .001). In regression analysis, significant variables included male sex, physician category, wound type, increased patient age, and increased wound age, area, and depth. The odds ratio varied considerably for each variable. The more frequent the debridements, the better the healing outcome. Although limited by retrospective data, this study's strength was the analysis of the largest wound data set to date.

A retrospective study of expert opinions of a psychosomatic-psychotherapeutic university hospital for public and private customers over a period of 12 years Objectives: Both the public and the legislative have developed an increasingly critical awareness for the fact that expert witnesses need to be independent. In contrast, to date there have been few studies concerning the quantity and the results of psychosomatic-psychotherapeutic expert opinions for public and private clients. In a retrospective study design, 285 expert opinions of a psychosomatic-psychotherapeutic university hospital stemming from consecutive, unselected random sampling over a 12-year time period (1990-2011) were analyzed using a predefined list of criteria. Besides client data, the study also noted the type and the objectives of the expertise, the sociodemographic data of the subjects, the biographic data of the subjects, the size of records, the particular psychopathological findings including conflict and structural diagnostics via the Operationalized Psychodynamic Diagnostics (OPD-2, Research Group 2006), syndromic diagnostics according to ICD-10 (WHO) including the related Impairment Scale Score (ISS, Schepank 1995), and the Global Assessment of Functioning-Scale (GAF, Heuft 2016). 54% of the subjects were men. All subjects were 46 years old at the time of examination; on average symptomatology had existed for 7 years, which made assessment of causality difficult. Most assignments referred to the effects of diseases or accidents in private contexts, followed by pension reports. Among the expert opinions related to possible implications of acts of violence, 95% were women. In 43.2% (n = 123) of the cases, the assessment had occurred in the context of legal action. In 65 cases at least one party had requested a supplemental written report during further procedure. In 17.8% (n = 22) of the cases sought by the courts, the expert witness was requested by at least one party to present the assessment verbally. It should be emphasized that OPD conflict and structural diagnostics appear indispensable also for assessing mental health prior to an external event (accident or assault). The use of the two severity ratings (ISS, GAF) is discussed. It is proposed that expert witnesses be requested to name all their clients fromthe last 5 years at the beginning or end of the expert opinion, so that their independence from possible conflicts of interest can be established.

To analyse differences in children and adolescents aged ≤18 years admitted to the leprosy ward in a rural Ethiopian hospital >16 years. We retrospectively collected data from leprosy admission registry books on patients with leprosy who were admitted to a referral hospital from September 2000 to September 2016. There were 2129 admissions for leprosy during the study period: 180 (8.4%) patients were s ≤ 18 years old. Of these, 98 (54.4%) were male and 82 (45.6%) were female. The proportion of new diagnoses in children and adolescents was 31.7%, significantly higher than in adults (11.7%; p < 0.001). There were also significant differences in the prevalence of lepromatous ulcers (46.9 vs. 61.7%), leprosy reaction (29.4 vs. 13.0%) and neuritis (16.9 vs.5.3%) between these age groups. There were more new diagnoses, leprosy reactions and neuritis, and fewer lepromatous ulcers, in children and adolescents compared with adults, with younger patients being referred more frequently to reference centres.

We have retrospectively examined the nature of acute mastioditis (in western Norway) during a 20 year period (1980-2000). Sixty-one cases of AM were identified in 57 patients with a mean age of 3.6 years. We found no significant change in the incidence of AM during the last 20 years. Seven patients were treated solely with intravenous antibiotics and myringotomies. Fifty patients also underwent cortical mastoidectomy, four cases with bilateral surgery. Antibiotic treatment was given to 31 of the patients before admission to hospital and this group had a significant longer duration of symptoms (12.4 days) compared to untreated patients (7.3 days). Streptococcus pneumoniae was the most common organism recovered from patient cultures. Surgery was found to correlate to patients with retroauricular fluctuation or to children with at least two of the three clinical signs: protrusion of the ear, retroauricular oedema and swelling of the ear canal. Our data show that clinical examination only reveal 50% of the cases with surgically proven retroauricular subperiostal abscess. We therefore recommend a CT scan of patients treated conservatively.

The aim of this study was to estimate the incidence of recurrent pregnancy loss (RPL). The prevalence of RPL defined as three or more consecutive miscarriages before gestation week 22, is often stated to be 1%. To our knowledge no study has estimated the incidence of RPL, which might be more informative and clinically relevant than the prevalence. This retrospective register-based study was conducted from 2003 until 2012 in Sweden with data provided by the Swedish National Board of Health and Welfare. In all, 6852 women were registered with the diagnoses of RPL in the National Patient Register. The incidence of RPL is the number of new women receiving the RPL diagnosis per year in the numerator and population at risk in the denominator. For each year, from 2003 to 2012, the incidence was calculated in two different risk populations: [1] all women aged 18-42 years, and [2] all women registered as being pregnant (deliveries or miscarriages). The average incidence in the study period was 53 per 100 000 (0.05%) in women aged 18-42 years and 650 per 100 000 (0.65%) in women who had achieved pregnancy in the period. The incidence of RPL in the two risk populations increased by 74 and 58%, respectively, during the study period. This study suggests that the incidence of RPL increased during the 10-year period studied. Causes can only be speculated upon in this study design, but might be associated with environmental changes, as the increase was fairly rapid. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Objective Fever of unknown origin (FUO) can be caused by many diseases, and varies depending on region and time period. Research on FUO in Japan has been limited to single medical institution or region, and no nationwide study has been conducted. We identified diseases that should be considered and useful diagnostic testing in patients with FUO. Design A nationwide retrospective study. Setting 17 hospitals affiliated with the Japanese Society of Hospital General Medicine. Participants This study included patients ≥18 years diagnosed with ‘classical fever of unknown origin’ (axillary temperature ≥38°C at least twice over a ≥3-week period without elucidation of a cause at three outpatient visits or during 3 days of hospitalisation) between January and December 2011. Results A total of 121 patients with FUO were enrolled. The median age was 59 years (range 19–94 years). Causative diseases were infectious disease in 28 patients (23.1%), non-infectious inflammatory disease in 37 (30.6%), malignancy in 13 (10.7%), other in 15 (12.4%) and unknown in 28 (23.1%). The median interval from fever onset to evaluation at each hospital was 28 days. The longest time required for diagnosis involved a case of familial Mediterranean fever. Tests performed included blood cultures in 86.8%, serum procalcitonin in 43.8% and positron emission tomography in 29.8% of patients. Conclusions With the widespread use of CT, FUO due to deep-seated abscess or solid tumour is decreasing markedly. Owing to the influence of the ageing population, polymyalgia rheumatica was the most frequent cause (9 patients). Four patients had FUO associated with HIV/AIDS, an important cause of FUO in Japan. In a relatively small number of cases, cause remained unclear. This may have been due to bias inherent in a retrospective study. This study identified diseases that should be considered in the differential diagnosis of FUO. PMID:24362014

The primary aims were to determine the rates of and prognostic factors for overall survival, disease-specific survival and disease-free survival following salvage total laryngectomy. Retrospective longitudinal study. Tertiary medical centres. A total of 142 patients in eastern Denmark undergoing salvage total laryngectomy for squamous cell carcinoma of the larynx or hypopharynx. 5-year overall survival, 5-year disease-specific survival, 5-year disease-free survival and prognostic factors for these outcomes. 5-year overall survival, disease-specific survival and disease-free survival were 37.7%, 54.9% and 55.3%, respectively. N classification at primary diagnosis, lymph node excision and postoperative complications within 1 year after salvage total laryngectomy were prognostic factors for shorter overall survival, disease-specific survival and disease-free survival. Residual tumour/recurrence was negatively associated with overall survival, close or involved resection margins with disease-specific survival, and second primary cancer was associated with longer disease-specific survival and disease-free survival. Nine per cent of all patients had residual tumour and 33.8% developed a recurrence. Our overall survival, disease-specific survival and disease-free survival findings are in accordance with previous studies. With the purpose of identifying recurrent tumour, we suggest extra attention being given to patients with higher N classification and need for lymph node excision during salvage total laryngectomy along with use of frozen sections. The high number of patients with recurrence within 1 year after salvage total laryngectomy occurred although thorough and regular follow-up visits were performed. © 2016 John Wiley & Sons Ltd.

Long-term employment trajectories of young problem drinkers are poorly understood. We constructed retrospective labour market participation histories at ages 18-34 of 64 342 persons born in 1969-1982. Beginning from the year of each subject's 18th birthday, we extracted information from the records of Statistics Finland on educational attainment, main type of economic activity, months in employment, and months in unemployment for a minimum of seven years (range 7-16 years). We used information on the timing of alcohol-related hospitalizations and deaths in the same period to define problem drinkers with early onset limited course, early onset persistent course, and late onset problem drinking. Early onset limited course problem drinkers improved their employment considerably by age, whereas early onset persistent problem drinkers experienced a constant decline in their employment by age. From the age of 18 to 34, early onset persistent problem drinkers were in employment merely 12% of the time, in comparison with 39% among the early onset limited course problem drinkers, and 58% among the general population. These results indicate that young adults who were retrospectively defined as having early onset persistent course problem drinking were extensively marginalized from the labour market early on during their life course, and that their employment trajectory was significantly worse compared to other problem drinkers.

Treatment results and prognostic factors of pediatric neuroblastoma: a retrospective study

PubMed Central

2010-01-01

Background We conducted a retrospective analysis to investigate treatment results and prognostic factors of pediatric neuroblastoma patients. Methods This retrospective study was carried out analyzing the medical records of patients with the pathological diagnosis of neuroblastoma seen at South Egypt Cancer Institute, Assiut University during the period from January 2001 and January 2010. After induction chemotherapy, response according to international neuoblastoma response criteria was assessed. Radiotherapy to patients with residual primary tumor was applied. Overall and event free survival (OAS and EFS) rates were estimated using Graphed prism program. The Log-rank test was used to examine differences in OAS and EFS rates. Cox-regression multivariate analysis was done to determine the independent prognostic factors affecting survival rates. Results Fifty three cases were analyzed. The median follow-up duration was 32 months and ranged from 2 to 84 months. The 3-year OAS and EFS rates were 39.4% and 29.3% respectively. Poor prognostic factors included age >1 year of age, N-MYC amplification, and high risk group. The majority of patients (68%) presented in high risk group, where treatment outcome was poor, as only 21% of patients survived for 3 year. Conclusion Multivariate analysis confirmed only the association between survival and risk group. However, in univariate analysis, local radiation therapy resulted in significant survival improvement. Therefore, radiotherapy should be given to patients with residual tumor evident after induction chemotherapy and surgery. Future attempts to improve OAS in high risk group patients with aggressive chemotherapy and bone marrow transplantation should be considered. PMID:21182799

Inborn errors of metabolism (IEMs) are individually rare; however, they are collectively common. More than 600 human diseases caused by inborn errors of metabolism are now recognized, and this number is constantly increasing as new concepts and techniques become available for identifying biochemical phenotypes. The aim of this study was to determine the type and distribution of IEMs in patients presenting to a tertiary care center in Saudi Arabia. We conducted a retrospective review of children diagnosed with IEMs presenting to the Pediatric Department of King Abdulaziz Medical City in Riyadh, Saudi Arabia over a 13-year period. Over the 13- year period of this retrospective cohort, the total number of live births reached 110,601. A total of 187 patients were diagnosed with IEMs, representing a incidence of 169 in 100,000 births (1:591). Of these, 121 patients (64.7 %) were identified to have small molecule diseases and 66 (35.3 %) to have large molecule diseases. Organic acidemias were the most common small molecule IEMs, while lysosomal storage disorders (LSD) were the most common large molecule diseases. Sphingolipidosis were the most common LSD. Our study confirms the previous results of the high rate of IEMs in Saudi Arabia and urges the health care strategists in the country to devise a long-term strategic plan, including an IEM national registry and a high school carrier screening program, for the prevention of such disorders. In addition, we identified 43 novel mutations that were not described previously, which will help in the molecular diagnosis of these disorders.

A retrospective study to compare the failure patterns and effects of elective nodal irradiation (ENI) or involved field irradiation (IFI) for cervical and upper thoracic esophageal squamous cell carcinoma (SCC) patients. One hundred and sixty nine patients with the cervical and upper thoracic esophageal SCC were analyzed retrospectively; 99 patients (59%) underwent IFI and 70 patients (41%) received ENI. We defined "Out-PTVifi in-PTVeni metastasis" as lymph node metastasis occurring in the cervical prophylactic field of PTVeni thus out of PTVifi. Out-PTVifi in-PTVeni cervical node metastasis occurred in 8% of patients in the IFI group, all within 2 years after treatment. However, it occurred in 10% of patients in the ENI group, and these failures happened gradually since one year after treatments. No difference was found in OS and the incidences of Grade ≥ 3 treatment-related esophageal and lung toxicities between the two groups. ENI for cervical and upper thoracic esophageal SCC patients did not bring longer OS and better long-term control of cervical lymph nodes. Although ENI might delay cervical nodes progression in elective field; it could not decrease the incidence of these failures.

The method for retrospective dose assessment based on the analysis of cell distribution by the number of dicentrics and unstable aberrations using a special computer program was earlier developed based on the data about the persons irradiated as a result of the accident at the Chernobyl nuclear power plant. This method was applied for the same purpose for data processing of repeated cytogenetic studies of the patients exposed to γ-, γ-β- or γ-neutron radiation in various situations. As a whole, this group was followed up in more distant periods (17-50 years) after exposure than Chernobyl patients (up to 25 years). The use for retrospective dose assessment of the multiple regression equations obtained for the Chernobyl cohort showed that the equation, which includes computer recovered estimate of the dose and the time elapsed after irradiation, was generally unsatisfactory (r = 0.069 at p = 0.599). Similar equations with recovered estimate of the dose and frequency of abnormal chromosomes in a distant period or with all three parameters as variables gave better results (r = 0.686 at p = 0.000000001 and r = 0.542 at p = 0.000008, respectively).

We discuss clinical symptoms and radiological findings of variable esophageal foreign bodies as well as therapeutic procedures in Caucasian pediatric patients. A retrospective study of 192 cases of suspected esophageal foreign bodies between 1998 and 2010 was conducted. Data were statistically analyzed by chi-square test. A foreign body was removed from a digestive tract of 163 children aged 6 months to 15 years (mean age 4.9). Most objects were located within cricopharyngeal sphincter. Dysphagia occurred in 43%, followed by vomiting (29%) and drooling (28%). The most common objects were coins. Plain chest X-rays demonstrated aberrations in 132 cases, and in doubtful situations an esophagram test was ordered. In the group of thirty-seven patients whose radiograms were normal, esophagoscopy revealed fifteen more objects, which were eventually successfully removed. No major complications occurred. Esophagram should be a second X-ray examination if an object is not detected in plain chest X-ray. We recommend a rigid esophagoscopy under general anesthesia in doubtful cases as a safe treatment for pediatric patients.

SUMMARY We undertook a 5-year retrospective study of group A streptococcal (GAS) bacteraemia in Fiji, supplemented by a 9-month detailed retrospective study of β-haemolytic streptococcal (BHS) infections. The all-age incidence of GAS bacteraemia over 5 years was 11·6/100 000. Indigenous Fijians were 4·7 times more likely to present with invasive BHS disease than people of other ethnicities, and 6·4 times more likely than Indo-Fijians. The case-fatality rate for invasive BHS infections was 28%. emm-typing was performed on 23 isolates: 17 different emm-types were found, and the emm-type profile was different from that found in industrialized nations. These data support the contentions that elevated rates of invasive BHS and GAS infections are widespread in developing countries, and that the profile of invasive organisms in these settings reflects a wide diversity of emm-types and a paucity of types typically found in industrialized countries.

Cystic echinococcosis is an important public health problem in our region. The aim of this study was to assess the surgical incidence of cystic echinococcosis in Sivas, Turkey. A retrospective follow-up study was carried out between 1997 and 2004. The mean age of 124 men (39.2%) and 192 women was 36.4 years. The liver was the primary site of cyst development (76.6%), followed by the lungs (19.9%), the spleen (5.4%), the kidneys (3.5%) and the peritoneal cavity (3.2%). Mean annual surgical incidence was 6.4 per 100,000 inhabitants for a 7-year period. The most common site of recurrence was the liver. Hepatic cysts were more frequently infected than pulmonary cysts (P < 0.05). In those patients with an infected cyst, the mean circulating eosinophil level was significantly lower than in those without. Rupture and infection were more common in men (P < 0.01). In conclusion, serious structural, legislative, surveillance, prevention and control measures for echinooccus should be undertaken in our region.

Elderly patients are often judged to be fit for emergency surgery based on age alone. This study identified risk factors predictive of in-hospital mortality amongst octogenarians undergoing emergency general surgery. A retrospective review of octogenarians undergoing emergency general surgery over 3 years was performed. Parametric survival analysis using Cox multivariate regression model was used to identify risk factors predictive of in-hospital mortality. Hazard ratios (HR) and corresponding 95% confidence interval were calculated. Seventy-three patients with a median age of 84 years were identified. Twenty-eight (38%) patients died post-operatively. Multivariate analysis identified ASA grade (ASA 5 HR 23.4 95% CI 2.38-230, p = 0.007) and chronic obstructive pulmonary disease (COPD) (HR 3.35 95% CI 1.15-9.69, p = 0.026) to be the only significant predictors of in-hospital mortality. Identification of high risk surgical patients should be based on physiological fitness for surgery rather than chronological age. Crown Copyright © 2014. Published by Elsevier Ltd.

Scalp cooling is an intervention used to decrease the degree of chemotherapy-induced alopecia. The objective is to determine the incidence of scalp metastases among women with early breast cancer who received neoadjuvant or adjuvant chemotherapy. We conducted a retrospective cohort study of women with breast carcinoma diagnosed between June 1, 1998 and June 30, 2002. The median follow-up was 5.8 years (+/-1.7) for the scalp cooling group (n = 553) and 5.4 years (+/-1.7) for the non-scalp cooling group (n = 87). The incidence of scalp metastases was 1.1% (6 cases out of 553 patients) among women who used scalp cooling in the neoadjuvant or adjuvant setting and 1.2% also (1 case out of 87 patients) among women who did not use scalp cooling in the neoadjuvant or adjuvant setting. The incidence of scalp metastases was low and no case presented as an isolated site of relapse.

Does Mid-Urethral Sling Surgery in the Treatment of Stress Urinary Incontinence Affect Weight Changes in Women? A Retrospective Cohort Study Using Internal Controls.

Stress urinary incontinence (SUI) is a common disorder among women. This is particularly bothersome to physically active women, such as those who serve in the Armed Forces. With the documented success of the midurethral sling (MUS) in the treatment of SUI, more women are electing to undergo surgical treatment. Studies document that women have less inhibition about exercise as a result of decreased incontinence following MUS surgery. We sought to determine if MUS surgery is associated with a change in weight postoperatively resulting from increased levels of activity following surgery. We hypothesized that women, particularly active duty (AD) women, would experience a decrease in weight and body mass index (BMI) in the year following the MUS procedure. This retrospective cohort study used the military electronic medical record system. The subjects included AD military and civilian (CV) patients who underwent MUS surgery at tertiary care centers between July 2006 and March 2013. Weight and BMI were recorded for three distinct time periods: 1-year preoperatively, at time of surgery, and 1-year postoperatively. A total of 207 women met inclusion criteria, 76 of which were AD women in the U.S. military. For the group as a whole, we found no significant difference in mean weight or BMI among the three time points examined; however, decreases in BMI and weight were noted in the year following surgery for the subgroups of AD and obese women. Analysis of covariance showed that age, parity, preoperative weight, and concomitant hysterectomy were not significant determinants for change in weight postoperatively. Despite its effective treatment of SUI, MUS surgery did not significantly affect the weight of patients postoperatively in our retrospective cohort.

Frequent alcohol drinking is associated with lower prevalence of self-reported common cold: a retrospective study

PubMed Central

2012-01-01

Background Alcohol intake has been associated with reduced incidence of common cold symptoms in 2 European studies. However, no study has addressed the association between the frequency of alcohol intake and the incidence of common cold. This study aimed to investigate the association between the amount and frequency of alcohol drinking and the retrospective prevalence of common cold in Japanese men. Methods This retrospective study included men who participated in an annual health examination conducted in Sendai, Japan. The frequency of common cold episodes in the previous year was self-reported. The weekly frequency and amount of alcohol consumed, as well as the type of alcoholic drink, were reported by a brief-type self-administered diet history questionnaire. Logistic regression models were used to analyze the association between the amount and frequency of alcohol intake and the retrospective prevalence of common cold. Results Among 899 men, 83.4% of the subjects reported drinking alcohol, and 55.4% of the subjects reported having experienced at least one episode of common cold in the previous year. Compared with non-drinkers, the adjusted odds ratios (ORs) with 95% confidence intervals (CIs) for having had 1 or more episodes of common cold during the past year across categories of alcohol intake frequency of 3 or less, 4–6, and 7 days/week were 0.827 (0.541–1.266), 0.703 (0.439–1.124), and 0.621 (0.400–0.965), respectively (P for trend = 0.025); the adjusted ORs with 95% CIs for having had of 2 or more episodes of common cold across the same categories were 0.642 (0.395–1.045), 0.557 (0.319–0.973), and 0.461 (0.270–0.787), respectively (P for trend = 0.006). Compared with subjects who consumed 11.5–35.8 g of alcohol per day, the non-drinkers were significantly more likely to experience 2 or more episodes of common cold (OR, 1.843; 95% CI, 1.115–3.047). Conclusion The frequency, not the amount, of alcohol intake was significantly related to lower prevalence of self-reported common cold episodes in Japanese men. PMID:23158193

The purpose of this study is first to report the outcomes, at 4 years follow-up, in revision ACL surgery using allografts in patients younger than 40 years old, and then compared soft tissue allografts to bone tendon allografts. This retrospective study included 47 patients who underwent ACL revision surgery with fresh-frozen allografts. Patellar tendon allograft or tibialis anterior allograft was used. Twenty-seven patients undergoing ACL revision with patellar tendon allograft were compared retrospectively with twenty-two patients undergoing the same procedure with soft tissue tibialis anterior allograft. Lysholm, IKDC, and KT-1000 values were obtained preoperatively and postoperatively. The average patient follow-up was 4.6 years (±2.5). The mean age at time of the revision was 34 years old (±6.3). Overall, patients reported the overall condition of their knee as excellent or good in 85% of the patients (10 excellent, 33 good). Based on their experience, 85% would have the surgery again if they had the same problem in the other knee. Both subgroups experienced significant improvement in Lysholm, IKDC, and KT-1000 values, with no difference found between groups at final follow-up. Revision ACL with allografts has excellent and good results in 85% of patients younger than 40 years old. No statistical difference was seen between soft tissue (tibialis anterior) and patellar tendon allograft. IV.

Complications from diabetes mellitus including major lower extremity amputation may have significant impact on a patient's mortality. This study determined what impact the addition of a limb salvage and diabetic foot program involving podiatry had at an academic institution over 16years by analyzing high-low amputation ratio data. The high-low amputation ratio in the diabetic population who underwent non-traumatic amputation of the lower extremity was retrospectively evaluated at an academic institution via cohort discovery of the electronic medical record and analysis of billing over 16years. We directly compared two eras, one without podiatry and one with a podiatry presence. It was found that with the addition of a podiatry program, limb salvage rates significantly increased (R 2 (without podiatry)=0.45, R 2 (with podiatry)=0.26), with a significant change in both the rate of limb salvage per year (-0.11% per year versus -0.36% per year; p<0.01) and an overall decrease in high-low amputation ratio (0.89 without podiatry to 0.60 with podiatry). Of note, approximately 40 major lower extremity amputations were avoided per year with the addition of a podiatry program (p<0.05). Our findings signify the importance of podiatric care in the diabetic population. With an established podiatry program present at an academic institution, major lower extremity amputations can be avoided and more limbs can be salvaged, thus preventing some of the moribund complications from this condition.

The aim of this study was to evaluate oral function rehabilitation in patients with hypohidrotic ectodermal dysplasia (HED) using implant-supported prostheses based on bone augmentation. From September 2005 and March 2009, 25 HED patients were chosen for clinical data analysis in this study. The criteria for patient selection included the following: the display of clinical features of HED, the number of congenitally missing teeth (>5), the patient age (>16 years), the patient's willingness, and the patient's tolerance for bone graft surgery and implant placement. Follow-up evaluations were initiated from the time of implant prosthetic placement and scheduled annually for 3-5 years. The effects of oral function reconstruction were assessed based on the cumulative survival and success rates of implants, the health of the peri-implant area, and the degree of patient satisfaction. Twenty-five HED patients received 169 conventional implants and 10 zygomatic implants (179 total implants). During 3-5 years of post-loading evaluations, 5 of the 179 implants failed and 3 implants were removed. The 3-year success and cumulative survival rates were 97.2% and 98.3%, respectively. Furthermore, periodontal probing and radiographic assessments showed that the 3-year incidence of peri-implantitis was 4.5%. Finally, HED patients expressed high degrees of satisfaction with their facial contours, masticatory function, pronunciation ability, and comfort with the implant-supported prostheses. The results of this 3- to 5-year retrospective study indicate that the oral function of HED patients can be effectively reconstructed using bone augmentation and implant-supported prostheses; however, longer term results are warranted in the future.

The lungs are among the first organ affected by remote metastases from many primary tumors. The surgical resection of isolated pulmonary metastases represents an important and effective element of therapy. This is a retrospective study about our entire experience with pulmonary resection for metastatic cancer using 1318-nm neodymium-doped yttrium-aluminum garnet laser. In this single-institution study, we retrospectively analyzed a group of 209 patients previously treated for primary malignant solid tumors. We excluded 103 patients. The number and location of lesions in the lungs was determined using chest computed tomography and positron emission tomography-computed tomography. Disseminated malignancy was excluded. All pulmonary laser resections are performed via an anteroaxillary muscle-sparing thoracotomy. All lesions were routinely removed by laser with a small (5-10 mm) margin of the healthy lung. Patients received systematic lymph node sampling with intraoperative smear cytology of sampled lymph nodes. Mortality at 2 years from the first surgery is around 20% (10% annually). This value increases to 45% in the third year. The estimated median survival for patients who underwent the first surgery is reported to be approximately 42 months. Our results show that laser resection of lung metastases can achieve good result, in terms of radical resection and survival, as conventional surgical metastasectomy. The great advantage is the possibility of limiting the damage to the lung. Stapler resection of a high number of metastases would mutilate the lung.

Carbon dioxide field flooding: a retrospective study.

Frados, A

2001-05-01

The carbon dioxide surgical field flooding technique has long been tried with varying degrees of success. A recent revival of the technique that began over 40 years ago in cardiac surgery, has brought promise as well as improved results attributable to improved technology. Studies at JFK Medical Center have been very successful using the carbon dioxide surgical field-flooding technique. Establishing new guidelines will assist other institutions in attempting this "old" technique with renewed success. Modern, more efficient equipment make use of carbon dioxide to displace intracardiac gases a safe procedure. The carbon dioxide field-flooding technique is safer, easier, and more efficacious than traditional de-airing techniques. This study shows that a long-standing procedure is valuable by observing the results, and, retrospectively evaluating stroke rates among cardiac valve cases at the hospital.

Objectives Long-term magnetic resonance angiography (MRA) follow-up studies regarding cryptogenic nonperimesencephalic subarachnoid hemorrhage (nSAH) are scarce. This single-centre study identified all patients with angiographically verified cryptogenic nSAH from 1998 to 2007: The two main objectives were to prospectively assess the incidence of de novo aneurysm with 3.0-MRI years after cryptogenic nSAH in patients without evidence for further hemorrhage, and retrospectively assess patient demographics and outcome. Methods From prospectively maintained report databases all patients with angiographically verified cryptogenic nSAH were identified. 21 of 29 patients received high-resolution 3T-MRI including time-of-flight and contrast-enhanced angiography, 10.2 ± 2.8 years after cryptogenic nSAH. MRA follow-up imaging was compared with initial digital subtraction angiography (DSA) and CT/MRA. Post-hemorrhage images were related to current MRI with reference to persistent lesions resulting from delayed cerebral ischemia (DCI) and post-hemorrhagic siderosis. Patient-based objectives were retrospectively abstracted from clinical databases. Results 29 patients were identified with cryptogenic nSAH, 17 (59%) were male. Mean age at time of hemorrhage was 52.9 ± 14.4 years (range 4 – 74 years). 21 persons were available for long-term follow-up. In these, there were 213.5 person years of MRI-follow-up. No de novo aneurysm was detected. Mean modified Rankin Scale (mRS) during discharge was 1.28. Post-hemorrhage radiographic vasospasm was found in three patients (10.3%); DCI-related lesions occurred in one patient (3.4%). Five patients (17.2%) needed temporary external ventricular drainage; long-term CSF shunt dependency was necessary only in one patient (3.4%). Initial DSA retrospectively showed a 2 x 2 mm aneurysm of the right distal ICA in one patient, which remained stable. Post-hemorrhage siderosis was detected 8.1 years after the initial bleeding in one patient (4.8%). Conclusion Patients with cryptogenic nSAH have favourable outcomes and do not exhibit higher risks for de novo aneurysms. Therefore the need for long-term follow up after cryptogenic nSAH is questionable. PMID:25688554

Background Nontuberculous mycobacterial pulmonary disease (NTM-PD) has become an emerging infectious disease and is responsible for more deaths than tuberculosis in industrialized countries. NTM-PD mortality remains high in some series reportedly ranging from 25% to 40% at five years and often due to unfavorable evolution of NTM-PD despite established treatment. The purpose of our study was to search for early factors that could predict the favorable or unfavorable evolution of NTM-PD at the first year of treatment. Methods In this retrospective and multicenter study, we selected 119 patients based on clinical, radiological and microbiological data from 2002 to 2012 from three French university hospitals (Guadeloupe, Martinique, Montpellier) with definite (meeting the criteria of the American Thoracic Society and the Infectious Disease Society of America in 2007; ATS/IDSA) or probable (one positive sputum culture) NTM-PD. We compared two patient groups: those who improved at one year (clinical symptoms, radiological lesions and microbiology data) and those who did not improve at one year. The data were analyzed for all patients as well as for subgroups by gender, HIV-positive patients, and Mycobacterium avium complex (MAC) infection. Results The average patient age was 50 years ± 19.4; 58% had respiratory comorbidities, 24% were HIV positive and 19% had cystic fibrosis. Coughing concerned 66% of patients and bronchiectasis concerned 45%. The most frequently isolated NTM were MAC (46%). 57% (n = 68) of patients met the ATS criteria and improved status concerned 38.6% (n = 46). The improvement factors at one year of NTM-PD were associated with the duration of ethambutol treatment: (Odds ratio adjusted [ORa]: 2.24, 95% Confidence interval [CI]; 2.11–3.41), HIV-positive status: (ORa: 3.23, 95% CI; 1.27–8.45), and male gender: (ORa: 2.34, 95% CI; 1.26–8.16). For the group with NTM-PD due to MAC, improvement was associated with the duration of macrolide treatment (ORa: 3.27, 95% CI; 1.88–7.30) and an age <50 years (ORa: 1.88, 95% CI; 1.55–8.50). Conclusion In this retrospective multicenter study, improvement at one year in patients with definite or probable NTM-PD was associated with the duration of ethambutol treatment, HIV-positive status and male gender. For the group of patients infected with MAC, improvement was associated with the duration of macrolide treatment and an age <50 years. Identifying predictors of improvement at one year of NTM-PD is expected to optimize the management of the disease in its early stages. PMID:28787454

Cumulative estrogen exposure and prospective memory in older women.

Hesson, Jacqueline

This study looked at cumulative lifetime estrogen exposure, as estimated with a mathematical index (Index of Cumulative Estrogen Exposure (ICEE)) that included variables (length of time on estrogen therapy, age at menarche and menopause, postmenopausal body mass index, time since menopause, nulliparity and duration of breastfeeding) known to influence estrogen levels across the life span, and performance on prospective and retrospective memory measures in a group of 50 postmenopausal women (mean age=69.3years) who, if they were current or former users of estrogen therapy, had started therapy within 5years of menopause. The ICEE was found to be a significant predictor of performance on the Prospective Memory task (F(1)=4.21, p=.046, η(p)(2)=.084). No significant relationship was noted between the ICEE and performance on measures of retrospective memory. The results suggest that the level of cumulative lifetime exposure to estrogen a woman has influences her prospective memory performance later in life and that the influence of reproductive and biological markers of endogenous estrogen exposure are relevant factors to consider when studying the effect of estrogen therapy on cognitive functioning in postmenopausal women. In addition, the finding that performance on a measure of prospective memory, but not performance on measures of retrospective memory, was associated with the ICEE adds further support to the theory that the frontal cortex may be especially sensitive to estrogen.

Statement of Problem: Early childhood is a crucial period of life as it affects one’s future health. However, precise data on adverse events during this period is usually hard to access or collect, especially in developing countries. Objectives: This paper first reviews the existing methods for retrospective data collection in health and social sciences, and then introduces a new method/tool for obtaining more accurate general and oral health related information from early childhood retrospectively. Materials and Methods: The Early Childhood Events Life-Grid (ECEL) was developed to collect information on the type and time of health-related adverse events during the early years of life, by questioning the parents. The validity of ECEL and the accuracy of information obtained by this method were assessed in a pilot study and in a main study of 30 parents of 8 to 11 year old children from Shiraz (Iran). Responses obtained from parents using the final ECEL were compared with the recorded health insurance documents. Results: There was an almost perfect agreement between the health insurance and ECEL data sets (Kappa value=0.95 and p < 0.001). Interviewees remembered the important events more accurately (100% exact timing match in case of hospitalization). Conclusions: The Early Childhood Events Life-Grid method proved to be highly accurate when compared with recorded medical documents. PMID:28959773

The aim of this retrospective hospital-based study was to review and evaluate the long-term outcome of patients with oral epithelial dysplasia (OED), with or without surgical intervention, to identify factors affecting clinical course and malignant evolution. Patients with a follow-up of at least 12 months were included. Data collected were statistically analyzed. The mean age was 63.58 years for women (n = 100) and 64.17 years for men (n = 107). One hundred and thirty-five of the patients had lesions with histopathological features of mild OED, 50 had moderate OED and 22 had severe OED. Gender and risk factors seemed not to be related with the development of OED. One hundred and thirty-three patients underwent active treatment. During the period considered, 39.4% of the 207 lesions disappeared; 19.66% remained stable and 33.7% of the total cases showed a new dysplastic event after treatment. Fifteen (7.24%) out of 207 developed a squamous cell carcinoma during follow-up. Our data showed that speckled lesions are more often associated with high histological grade. The risk of malignant development does not seem to be predictable. Surrounded by the limitations of the retrospective designs, we have showed that there is no eminent benefit of surgical intervention of OED in preventing recurrences and malignant development.

The efficacy of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) in elderly patients with non-small-cell lung cancer (NSCLC) remains uncertain. This retrospective study aimed to evaluate the efficacy and feasibility of EGFR-TKIs for NSCLC patients aged ≥ 80 years. We analyzed data from 21 NSCLC patients aged ≥ 80 years who were administered gefitinib and/or erlotinib between January, 2009 and December, 2014. The clinical characteristics, smoking status, type of EFGR mutation and the efficacy and toxicity of EGFR-TKIs were evaluated in these patients. In total, 14 (66.7%), 5 (23.8%) and 2 patients (9.5%) displayed partial response, stable disease and progressive disease, respectively. The median progression-free survival was 182 days, whereas the median overall survival was 371 days. Adverse events ≥ grade 2 were as follows: skin toxicities, 12 patients; liver function test abnormalities, 7 patients; anorexia, 3 patients; and diarrhea, 2 patients. Dose reduction of EGFR-TKIs due to adverse events was required in 15 patients (71.4%). Although gefitinib and erlotinib therapy may be beneficial in patients aged ≥ 80 years, EGFR-TKI dose modification may be necessary according to the overall medical condition of elderly patients. Further studies are required to evaluate our findings. PMID:25798276

Despite many educational campaigns we still see burns caused by methylated spirit every year. We undertook a retrospective study to analyse the impact of this problem. We retrospectively collected data of all patients with burns caused by methylated spirit over twelve years from 1996 to 2008. Our main endpoints were: incidence, age, mechanism of injury, total body surface area (TBSA) burned, burn depth, need for surgery and length of hospital stay. Ninety-seven patients with methylated spirit burns were included. During the study period there was no decrease in the number of patients annually admitted to the burn unit with methylated spirit burns. 28% of the patients (n=27) were younger than eighteen years old, 15% (n=15) were ten years old or younger. The most common cause of burns was carelessness in activities involving barbecues, campfires and fondues. Mean TBSA burned was 16% (SD 12.4). 70% (n=68) had full thickness burns. 66% (n=64) needed grafting. Mean length of hospital stay was 23 days (SD 24.7). The use of methylated spirit is an ongoing problem, which continues to cause severe burns in adults and children. Therefore methylated spirit should be banned in households. We suggest sale only in specialised shops, clear labelling and mandatory warnings. Copyright © 2012 Elsevier Ltd and ISBI. All rights reserved.

To identify the frequency and causes of uveitis leading to visual impairment in patients referred to the Low Vision Service - Department of Ophthalmology - UNIFESP, over a twenty years period. In a retrospective study, medical records of 5,461 patients were reviewed. Data from the first clinical evaluation at the Low Vision Service were collected, patient's age, gender and cause of visual impairment were analyzed. Patients with uveitis had their chart reviewed for anatomical classification and clinical diagnosis. The mean age of the patients referred to the Low Vision Service was 42.86 years and the mean age of patients with uveitis diagnosis was 25.51 years. Retinal disorders were the most common cause of visual impairment (N=2,835 patients; 51.9%) followed by uveitis (862 patients, 15.7%). Uveitis was posterior in 792 patients (91.9% of uveitis) and toxoplasmosis was the most common diagnosis (765 patients, 88.7%). In our study, uveitis represents the second cause of visual impairment in patients referred for visual rehabilitation and toxoplasmic retinochoroiditis was the most common clinical diagnosis. It affects a young working age population with a relevant social and economic impact, but the early diagnosis and treatment can improve the quality of life of these patients.

Background Carcinoma vulva is a rare disease accounting for 1.3% of all gynaecological malignancies. The present study is a 10-year retrospective review of our experience of the surgical options, morbidity, failure pattern, and survival for invasive carcinoma vulva. Materials and Methods Retrospective analysis of case records of 39 patients who underwent surgery for invasive vulval cancer between 2004 and 2013 in the Department of Surgical Oncology at the Government Royapettah Hospital, Chennai. Results The median age was 55 years. Radical vulvectomy was the preferred surgery. 31 patients underwent lymphadenectomy. Seroma formation and groin skin necrosis were the most common postoperative complications. With a median follow-up of 32 months, 8 patients (20.5%) developed recurrence (systemic = 1, regional = 4, and local = 3). The estimated 5-year disease-free survival (DFS) was 65.4% and the overall survival (OS) was 85.1%. On univariate analysis, stage and lymph node involvement significantly affected OS. Nodal involvement with extracapsular spread (ECS) significantly affected both DFS and OS. Conclusion The treatment of carcinoma vulva should be individualized with multidisciplinary cooperation. The paucity of data, especially from India, necessitates the need for more studies, preferably multicentric, keeping in mind the low prevalence. PMID:29387486

With the growing demand for dental work, trigeminal nerve injuries are increasingly common. This retrospective cohort study examined 53 cases of iatrogenic trigeminal nerve injury seen at the Department of Oral and Maxillofacial Surgery, University Hospitals of Leuven between 2013 and 2014 (0.6% among 8845 new patient visits). Patient records were screened for post-traumatic trigeminal nerve neuropathy caused by nerve injury incurred during implant surgery, endodontic treatment, local anaesthesia, tooth extraction, or specifically third molar removal. The patients ranged in age from 15 to 80years (mean age 42.1years) and 68% were female. The referral delay ranged from 1day to 6.5years (average 10months). The inferior alveolar nerve (IAN) was most frequently injured (28 cases), followed by the lingual nerve (LN) (21 cases). Most nerve injuries were caused during third molar removal (24 cases), followed by implant placement (nine cases) and local anaesthesia injuries (nine cases). Pain symptoms were experienced by 54% of patients suffering IAN injury, compared to 10% of patients with LN injury. Persistent neurosensory disturbances were identified in 60% of patients. While prevention remains the key issue, timely referral seems to be a critical factor for the successful treatment of post-traumatic neuropathy. Copyright © 2018 The Author(s).

Childhood allergic contact dermatitis is recognized as a significant clinical problem. The objective was to evaluate the rate of positive patch tests in Israeli children with clinically suspected allergic contact dermatitis, identify possible sex and age differences, compare results with those in Israeli adults, and review pediatric studies in the literature. The study sample included 343 children and adolescents (197 female, 146 male; 1-18 years of age, mean age 11.8 years) with clinically suspected allergic contact dermatitis who underwent patch testing with a standard pediatric series of 23 allergens at a tertiary medical center from 1999 to 2012. Data on clinical characteristics and test results were collected retrospectively from the medical files. Ninety-eight subjects (28.6%) (75 girls [38.1%], 23 boys [15.8%]) had at least one positive reaction. The most frequent reactions were to nickel sulfate, followed by potassium dichromate and cobalt chloride. Nickel sulfate sensitivity was more common in girls, especially those younger than 3 years and older than 12 years. The prevalence of contact sensitization was similar in subjects with and without atopic dermatitis (50% and 51%, respectively). Nickel is the most common allergen in Israeli children, especially girls. Patch testing should be performed in children with clinically suspected allergic contact dermatitis regardless of atopic background. © 2017 Wiley Periodicals, Inc.

A retrospective cross-sectional study was used to analyse pyometra cases at five RSPCA Animal Hospitals across the UK from 2006 to 2011. A total of 1728 cases of pyometra were recovered from a female dog outpatient caseload of 78,469 animals, giving a total prevalence of 2.2 per cent over the study period. There was an annual increase in the incidence of pyometra within the population, while elective ovariohysterectomy caseload has declined. There were variations in breed and age at presentation. Bullmastiffs (P<0.0001), golden retrievers (P=0.001) and dogue de Bordeaux (P=0.008) were over-represented in the pyometra population when compared with the female dog outpatient caseload. Mean age at presentation was 7.7 years. Some breeds presented at a significantly lower age, including dogue de Bordeaux (mean age 3.3 years) and bullmastiffs (mean age 5.4 years), while others presented as older dogs, including Yorkshire terriers (mean age 9.4 years) and border collies (mean age 10.3 years). Surgical mortality rate at the Greater Manchester Animal Hospital was 3.2 per cent. Pyometra is of significant welfare concern, and also has cost implications, particularly in charity practice. These results serve to highlight this condition so that future change in charity practice caseload can be anticipated and strategies can be directed to improve animal welfare. PMID:24114733

The present work was carried out to study the prevalence of Tinea capitis (TC) in Campania over a 9-year period and also to delineate the prevalence of the causative fungus responsible and the clinical forms of tinea capitis. This retrospective study included all the cases of TC occurring between January 2004 and December 2012 to the Mycology Laboratory at the University of Naples "Federico II" and mycologically confirmed. Samples for potassium hydroxide 20% mounts and fungal cultures were collected. Sabouraud dextrose agar were inoculated with the samples. TC was diagnosed by direct microscopy and culture in 143 patients. TC was found to be most common in the group including patients aged between 1-18 years; 13% of patients were over 18 years old. Non-inflammatory clinical forms were the most common type (80.4%). M. canis was the dermatophyte most frequently isolated (64.1%). Microscopic examination revealed an ectothrix pattern of hair invasion to be more common (72% cases). TC was clinical and mycologically diagnosed in 143 patients. It was prevalent in patients aged 1-18 years old; 73.2% of adults affected by TC had possible risk factors and in these patients TC often presented in atypical forms; atypical forms were also observed in children. M. canis was the most common dermatophyte species isolated in children, T. rubrum in adults. We noticed a significant increase of anthropophilic dermatophytes possibly linked to the immigration from African countries. For the diagnosis of TC, mycological examinations are essential.

Tarquini, Giacomo

This retrospective study aimed to compare the effectiveness of an equine collagen matrix (ECM) with that of a subepithelial connective tissue graft (CTG) in patients affected by Class I and II gingival recessions treated with a coronally advanced flap (CAF) technique. Records of 50 consecutive patients were analyzed. Recession depth, probing depth, keratinized tissue width, and percentage of root coverage had been recorded at baseline and at the 1-year follow-up. The number of patients that achieved complete root coverage was also assessed. According to the investigated parameters, ECM and CTG provide similar results when used in association with a CAF technique.

ABSTRACT Objective: To assess socio-demographic characteristics of patients undergoing total knee arthroplasty (TKA) in a public university hospital, evaluating the outcome infection and associated factors. Method: A retrospective study was carried out with 78 patients undergoing TKA, from 2013 to 2014. The socio-demographic and clinical characteristics of the patients were collected. Comparison between infected and non-infected patients was performed to find out which variables were possibly associated to this complication. Result: Of 81 arthroplasties performed, patients were older (mean age 64 years), women (79%), with primary osteoarthritis as main etiology (87.6%) and most had comorbidities (82.7%). Infection occurred in 16% of patients, and this outcome associated with age older than 65 years (p=0.023) and the occurrence of deep vein thrombosis (p=0.027). Conclusion: Patients undergoing TKA are mostly elderly women with primary osteoarthritis in the knee and comorbidities who developed infection in 16% of cases. More studies need to be conducted aimed at creating specific protocols in order to improve the quality of clinical practice. Level of Evidence III, Retrospective Comparative Study. PMID:28924354

To determine the prospective association between retrospectively assessed physical work environment during working life and prospectively assessed sickness absence and labour market exit among older workers. Using Cox regression analyses we estimated the 4-year to 6-year prospective risk of register-based long-term sickness absence (LTSA), disability pension, early retirement and unemployment from exposure to different physical work environmental factors during working life among 5076 older workers (age 49-63 at baseline) from the Copenhagen Aging and Midlife Biobank cohort. Very hard physical work throughout working life was a risk factor for LTSA (HR 1.66,95% CI 1.32 to 2.07), disability pension (HR 2.21,95% CI 1.04 to 4.72) and early retirement (HR 1.57,95% CI 1.13 to 2.17). Both short-term (<10 years) and long-term (≥20 years) exposures to lifting or carrying of heavy burdens predicted the risk of LTSA (HRs 1.49-1.56) and disability pension (HRs 2.26-3.29). In contrast, exposure to dust was associated with LTSA and disability pension only following 20 or more exposure years. Retrospectively assessed hard physical work during working life and exposure to several factors in the physical work environment, especially heavy lifting, were important for labour market exit and sickness absence. This study underscores the importance of reducing physical work exposures throughout the working life course for preventing sickness absence and premature exit from the labour market. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Andrade, Neelam N; Choradia, Smriti; Sriram S, Ganapathy

2015-09-01

In maxillofacial surgery, children represent a special group of patients, as they have significant differences from adults as far as the facial skeleton is concerned. The etiology and epidemiology of pediatric trauma involving the facial skeleton has been reported in a large series of patients. Nevertheless, few of these reports review large numbers of pediatric patients, and little is known about treatment protocols for fractures in children. The aims of this study were to retrospectively analyze the treatment methods and outcomes of pediatric mandibular fractures in children and young adolescents up to the age of 15 years, to discuss the findings, and to propose treatment protocols for maxillofacial fractures in childhood. The present study retrospectively analyzed the treatment methods and outcome of the pediatric mandibular fractures in children and young adolescents' up to the age of 15 years over a period of 5 years. All patients were followed up for an average period of 18 months, with a maximum follow-up of 2 years. A total of 74 patients were treated for mandibular and dentoalveolar fractures in children upto the age of 15 years at the Department of Oral and Maxillofacial Surgery at Nair Hospital Dental College, Mumbai from 2007 to 2012. AND CONCLUSIONS: The treatment methods used at our centre had satisfactory outcomes at the end of a follow-up period of 2 years. Reported complications were minimal. Our results confirm the usefulness of open reduction and plate fixation in older children (>12 years of age) and a conservative approach in younger children (≤12 years of age) in treating mandibular fractures.

Community acquired-Clostridium difficile infection (CDI) has increased also in children in the last years. To determine the incidence of community-acquired CDI and to understand whether Clostridium difficile could be considered a symptom-triggering pathogen in infants. A five-year retrospective analysis (January 2007-December 2011) of faecal specimens from 124 children hospitalized in the Niguarda Ca' Granda Hospital for prolonged or muco-haemorrhagic diarrhoea was carried out. Stool samples were evaluated for common infective causes of diarrhoea and for Clostridium difficile toxins. Patients with and without CDI were compared for clinical characteristics and known risk factors for infection. Twenty-two children with CDI were identified in 5 years. An increased incidence of community-acquired CDI was observed, ranging from 0.75 per 1000 hospitalizations in 2007 to 9.8 per 1000 hospitalizations in 2011. Antimicrobial treatment was successful in all 19 children in whom it was administered; 8/22 CDI-positive children were younger than 2 years. No statistically significant differences in clinical presentation were observed between patients with and without CDI, nor in patients with and without risk factors for CDI. Our study shows that Clostridium difficile infection is increasing and suggests a possible pathogenic role in the first 2 years of life. Copyright © 2015 Editrice Gastroenterologica Italiana S.r.l.

Objective. To determine any changes in tuberculosis epidemiology in the last 15 years in Benin, seasonal variations, and forecasted numbers of tuberculosis cases in the next five years. Materials and Methods. Retrospective cohort and time series study of all tuberculosis cases notified between 2000 and 2014. The “R” software version 3.2.1 (Institute for Statistics and Mathematics Vienna Austria) and the Box-Jenkins 1976 modeling approach were used for time series analysis. Results. Of 246943 presumptive cases, 54303 (22%) were diagnosed with tuberculosis. Annual notified case numbers increased, with the highest reported in 2011. New pulmonary bacteriologically confirmed tuberculosis (NPBCT) represented 78%  ± SD 2%. Retreatment cases decreased from 10% to 6% and new pulmonary clinically diagnosed cases increased from 2% to 8%. NPBCT notification rates decreased in males from 2012, in young people aged 15–34 years and in Borgou-Alibori region. There was a seasonal pattern in tuberculosis cases. Over 90% of NPBCT were HIV-tested with a stable HIV prevalence of 13%. The ARIMA best fit model predicted a decrease in tuberculosis cases finding in the next five years. Conclusion. Tuberculosis case notifications are predicted to decrease in the next five years if current passive case finding is used. Additional strategies are needed in the country. PMID:27293887

Ectodermal dysplasias form a complex, nosologic group of diseases with defects in at least 2 ectodermal structures. A retrospective study of patients with ectodermal dysplasia seen at our department over a period of 19 years (1994-2013) was performed. The study population consisted of 67 patients covering 17 different diagnoses. Forty-five families were identified of which 26 were sporadic cases with no affected family members. In 27 tested families a disease-causing mutation was identified in 23 families. Eleven mutations were novel mutations. To our knowledge, we present the first large ectodermal dysplasia cohort focusing on clinical manifestations in combination with mutational analysis. We recommend a nationwide study to estimate the prevalence of the ectodermal dysplasia and to ensure relevant molecular genetic testing which may form the basis of a national ectodermal dysplasia database.

Severe child abuse in north-east Wiltshire was studied retrospectively during the period 1965-71, and prospectively for 18 months from January 1972, after a period of consultative activity with those actively involved to increase awareness of the phenomenon. Severe abuse was strictly defined. A rate of 1 per thousand children under four years old was obtained, together with a death rate of 0-1 per thousand. The families of the retrospective series of abused children were studied in detail and identifying characteristics of large family size, youthfulness, low social-class, instability, and gross psychiatric, medical, and social pathology described. The implications of the ascertainment and death rates are discussed in relation to data from some other studies, and the need emphasized for detailed studies of the apparent clustering of disorder in the families, using linked record systems.

Uterine sarcomas are rare, malignant, gynecological tumors and show diverse histopathological features. Therefore, there is no consensus on risk factors for poor outcome and optimal treatment. The aim of this retrospective analysis is to report the clinical outcome of patients with uterine sarcoma treated at a single center. The data was obtained regarding the patient's demographic characteristics, pathological results, treatments given, survival, and complications of all uterine sarcoma patients treated in a single center between the years 2000 and 2012. The 80.month overall survival. (OS) was determined with respect to prognostic factors including age, stage of disease, histopathological type, and adjuvant treatment. A total of 57 case records are retrieved for this retrospective analysis. The mean age of the patients is 62.5 ± 11.2 years. International Federation of Gynecology and Obstetrics (FIGO) stage distribution is stage I: 29; stage II: 13; stage III: 9; stage IV: 6. Fifty-seven patients underwent surgery, 33 received postoperative radiotherapy (PORT), and 32 received chemotherapy. Median follow-up period was 25 months (range 2-85 months). The 80-month OS for the entire group of patients was 36.7%. The significant prognostic factors for survival are age under 50 years, stage of disease, and adjuvant chemotherapy. Although limited by small sample size and retrospective nature, age under 50 years, stage of disease, and adjuvant chemotherapy are significant prognostic factors for survival for uterine sarcomas.

Laparoscopic sleeve gastrectomy (LSG) is gaining popularity worldwide. This retrospective cohort study evaluated the outcomes of a large cohort of patients with obesity who underwent LSG in a Bariatric Center of Excellence. All consecutive patients who underwent LSG between July 2013 and April 2016 were identified retrospectively. Preoperative and postoperative variables and comorbidities were recorded. The study consisted of 750 patients. Their mean age was 37.4 years; 72% were women, and the mean body mass index was 42.8 kg/m. The most common preoperative comorbidities were diabetes (23.3%), hyperlipidemia (21.9%), hypertension (21.1%), and obstructive sleep apnea (21.1%). The rates of comorbidity resolution during follow-up were 80.6%, 74.4%, 82.9%, and 94.3%, respectively. The percentage average excess weight loss 1, 3, and 6 months and 1 and 2 years after surgery was 29.4%±11.3%, 54.4%±17.7%, 76.9%±20.9%, 85.5%±23.6%, and 89.7%±27.6%, respectively. There was no mortality. LSG effectively and safely induced weight loss and comorbidity resolution.

This retrospective study was carried out to evaluate the indications for and outcomes of the hemiclamshell (HCS) approach (longitudinal partial sternotomy with antero-lateral thoracotomy) in patients undergoing mass resection in thoracic surgery. All patients (50) who underwent a HCS procedure in our department, between July 1996 and July 2005, were studied retrospectively, analyzing the indications, morbidity and outcome (pain, neurological or shoulder defects, mortality) at one month and one year. The main indications were apical tumours (38%), tumours of the cervicothoracic junction (46%) and chest wall (10%), and 'bulky' tumours (6%). One-month mortality was 6%. Two patients suffered from a chylothorax and one from phrenic paralysis. The postoperative analgesic requirements were similar to those after other thoracic surgery approaches. Twelve percent of patients suffered pain at one month and 6% at one year. Shoulder dysfunction was observed in 10% of patients at one month and 6% at one year. In conclusion, the HCS surgical approach was associated with an uncomplicated postoperative course. This anterior approach is suitable for apical tumours, tumours of the cervicothoracic junction and 'bulky' lung tumours, providing good access for control of the large vessels and radical mediastinal clearance.

Distal biliary stricture is a challenging clinical condition that requires a co-ordinated multidisciplinary approach. was to evaluate the predictors of success of different treatment modalities of distal two thirds CBD strictures. Data were retrieved retrospectively from the medical records of the patients with distal biliary strictures treated in the Main Alexandria University Hospital from June 2013 to June 2015. Patients were classified into three groups according to the intervention performed: (endoscopic, open surgical, and percutaneous). In addition to the forth group that was followed up without intervention. The study included 282 patients. The mean age was 61.1 ± 10.8 years (25-78) years. The most frequent presenting symptom was jaundice. Pancreatic adenocarcinoma was the most common cause followed by fibrotic stricture secondary to stones. In univariate analysis, the success of treatment was significantly associated with the pathology of the stricture of the distal two thirds CBD. In the multivariate analysis, only two factors were affecting the success of the treatment; the stricture length and site. Copyright © 2016 IJS Publishing Group Limited. Published by Elsevier Ltd.

Skin cancer is the most common cancer worldwide; one in every three diagnosed malignancies is a skin cancer. However, skin cancer is rarely reported in Saudi Arabia so we conducted this study to highlight these underreported neoplasms. Determine the prevalence and patterns of basal cell carcinoma (BCC) and primary squamous cell carcinoma (SCC), the most common types of nonmelanoma skin cancer (NMSC) with respect to age, sex, and anatomic location and to identify potentially associated risk factors. Retrospective, descriptive medical record review. A tertiary care centre. We did a retrospective chart review of all patients diagnosed with basal cell carcinoma and primary squamous cell carcinoma between 2003-2016. Prevalence and pattern of BCC and SCC with respect to age, sex, and anatomic location. Of 593 cases reviewed, 279 had NMSC. Most (95%) were diagnosed with BCC or SCC or both in a few cases. The mean age at diagnosis was 59 (19.5) years. Sixty-two percent of the patients were males. However, 24.3% (n=68) of skin cancers occurred in patients younger than 50 years. The frequency of BCC and SCC was 50.2% and 44.8%, respectively. The head and neck was the most common location (79.6%). In patients younger than 50 years, xeroderma pigmentosum and previously treated solid malignancies were the major factors. BCC and SCC are uncommon but not rare. However, skin cancers are underreported in our population. NMSC in individuals younger than 50 years of age requires more careful evaluation of possible risk factors.

Ramkumar, Prem; Navarro, Sergio Michael

2017-01-01

Objectives: The primary goal of this study was to assess the short-term outcomes among National Football League (NFL) players following concussion in terms of: (1) DNP protocol activation, (2) release rate at one and three years, and (3) mean salary reduction. A secondary goal of the study was to stratify the post-concussive release rate by franchise and player position. Methods: NFL player transaction records and publicly available weekly injury reports from August 2005 to January 2016 for NFL players were analyzed. All players immediately sustaining recorded concussions were evaluated for a change to inactive or do-not-play (DNP) status. The one-year and three-year release rate following concussion was defined as any player transitioning to inactivation, retirement, free agency, or any failure to return for a successive season on the same team’s active roster after one or three years from the initial concussion. Student’s t-test was used to compare release rates between non-concussed and concussed players at one and three years. Mean salary reduction per year following concussion was calculated using publicly available player contracts. Additionally, franchise-level and position-based analyses of the release rate were performed. Results: Of the total 5,451 NFL players retrospectively analyzed over the 11-year period, 373 sustained publicly reported concussions resulting in DNP protocol activation. The release rate of the post-concussive versus non-concussive player was 26% vs. 20% at 1 year (p<0.01) and 31% vs. 19% at 3 years (p<0.01). After analyzing individual player contracts, the mean year-over-year change in contract value for concussed players after DNP protocol activation was an overall salary reduction of $760,000/year ± $2,380,000. Figure 1 depicts the tendency of each NFL franchise to release an athlete following concussion within one and three years. Table 1 reports a position-based analysis in terms of concussion rate, mean salary reduction, and NFL career longevity. Conclusion: Our retrospective study demonstrates that NFL concussions resulting in DNP protocol activation leads to a statistically greater release rate among concussed NFL players than non-concussed players. Released players suffered reduction in year-over-year accumulated earnings, and particular franchises tended to release concussed players more than others.

Recent population-based studies of measles incidence and deaths in Sudan are not available. To determine the epidemiology and case-fatality rate (CFR) of measles, we conducted a retrospective outbreak investigation in two states in northern Sudan. Of 1144 case-patients identified, 92% were <15 years; 48.6% were vaccinated; and 62% received vitamin A before illness. Ten measles-associated deaths were identified (CFR 0.9%; 95% confidence interval 0.16-1.91). CFR determined by this investigation is lower than expected for the region but remains 10 times higher than that in developed countries. Measles control should be strengthened by improving vaccine coverage, measles surveillance and case-management.

Tracheobronchial foreign body aspiration is a common emergency in childhood constituting major cause of mortality. Although ample studies regarding airway foreign bodies are present in western literature, studies in Indian context are however lacking. The aim of the study is to present an epidemiological data regarding airway foreign bodies in Indian context thereby helping to analyze the situation with regard to our socio-economic condition. Retrospective file review of all case (n = 82) that underwent rigid bronchoscopy for suspected tracheo-bronchial foreign body over a period of 7 years (2001-2008) in the department of otolaryngology of a tertiary care centre of eastern India. Patient characteristics, history, clinical, radiographic and bronchoscopic findings were noted in an attempt to define the epidemiology, clinical presentation, management and associated morbidity. Most common age of presentation was between 1 and 3 years (56.4%). Most common symptom in our study was Cough, wheezing and respiratory distress (63.4%). Most common clinical signs at presentation were diminished breath sound in unilateral lung field seen in 36.6% cases. Most common radiological finding on chest radiograph was collapse seen in 41.65% cases. Most common type of foreign body below 3 years of age was food material (seeds, beans) removed in 48.78%. Complications were encountered in 14.6% cases of which most common complication was bronchospasm and acute respiratory distress seen in 41.6% cases.

Although the incidence and risk factors of child abuse have been well researched, there continues to be a need for large studies that provide information regarding the process of recognizing children whose health and lives are most seriously threatened by abuse and neglect, in particular children requiring hospitalization as a result of child abuse. The purpose of this study was to (1) describe differences in the type of injuries and illnesses of children hospitalized for abuse and neglect and (2) assess the relationship between in-hospital mortality and child maltreatment. For this retrospective cohort study, child maltreatment cases were identified using medical record databases of patients treated in all hospitals and trauma units in Illinois. A comparison group of children not suffering from suspected maltreatment were randomly selected and matched by age and data source to the suspected maltreatment cases. 2656 children under the age of 13 years suspected of suffering maltreatment who were admitted to any hospital in Illinois between 2000 and 2009. The analysis showed distinct patterns in injury, physical illness and psychological disorders for each subgroup of maltreatment cases. Among the cases of maltreatment 75.6% were discharged home, 2.9% into child protective services and 15.8% to an intermediate care facility. In the final multivariable conditional logistic regression model, children suffering maltreatment continued to have a higher odds of dying during hospitalization (adjusted OR=2.99; CI95%: 1.63, 5.45; p<0.001). There were distinct diagnostic patterns and outcomes among suspected cases of child maltreatment admitted to Illinois hospitals over a 10-year period. This large retrospective cohort study confirms findings reported in many smaller studies and larger national cross-sectional surveys. Copyright © 2012 Elsevier Ltd. All rights reserved.

Objective: To investigate the class, type, position, diagnosis and most common procedures used in the surgical removal of third molars, and evaluate the sex and age distribution in a representative sample of Mexican patients. Study Design: A retrospective descriptive study was made covering the period 1993-2008 in relation to 9148 extracted third molars in 3206 patients treated in the Dental School of Salle Bajío University, A.C. (Mexico). Patients of either sex and aged 11-59 years, with at least one third molar programmed for surgical removal, were included in the study. A descriptive statistical study was made. Results: The mean patient age was 27.6 ± 10.6 years. There were 2093 females (65.3%) and 1111 males (34.6%). In relation to the 4025 upper molars, extraction was decided for prophylactic reasons in 3827 cases (95.08%). Type A presentations were recorded in 1929 cases (47.9%), with a vertical position in 1931 teeth (48%). In relation to the 5123 lower third molars, extraction was likewise most often indicated for prophylactic reasons (4424 cases, 86.36%). A total of 2353 teeth corresponded to type A (45.9%), 2545 were class I cases (49.7%), and a mesioangular position was observed in 1850 cases (36.1%). Conclusions: The present study shows that in Mexican patients, upper third molars most often correspond to type A and class I, with a vertical position, while lower third molars predominantly correspond to type A and class I, with a mesioangular position. This information can help dental surgeons take better decisions before and after surgery, to the benefit of their patients. Key words:Third molars, retrospective review, surgical removal.

The goal of this article was twofold, and a 2-study approach was conducted. The first study aimed to expose the anthropometrical, physical performance, and motor coordination characteristics that influence dropout from a high-level soccer training program in players aged 8-16 years. The mixed-longitudinal sample included 388 Belgian youth soccer players who were assigned to either a "club group" or a "dropout group." In the second study, cross-sectional data of anthropometry, physical performance, and motor coordination were retrospectively explored to investigate which characteristics influence future contract status (contract vs. no contract group) and first-team playing time for 72 high-level youth soccer players (mean age = 16.2 years). Generally, club players outperformed their dropout peers for motor coordination, soccer-specific aerobic endurance, and speed. Anthropometry and estimated maturity status did not discriminate between club and dropout players. Contract players jumped further (p = 0.011) and had faster times for a 5-m sprint (p = 0.041) than no contract players. The following prediction equation explains 16.7% of the variance in future playing minutes in adolescent youth male soccer players: -2,869.3 + 14.6 × standing broad jump. Practitioners should include the evaluation of motor coordination, aerobic endurance, and speed performances to distinguish high-level soccer players further succeeding a talent development program and future dropout players, between 8 and 16 years. From the age of 16 years, measures of explosivity are supportive when selecting players into a future professional soccer career.

Rattlesnake envenomation occasionally results in repetitive small-muscle fasciculations known as myokymia. We report the results of a retrospective inquiry of this phenomenon from a statewide poison center's database. Data was obtained from a poison system database for the years 2000-2003, inclusive, for rattlesnake envenomation exposures coded as having fasciculations. A total of 47 cases were identified, and nine other cases were found from previously published literature. There was no consistent temporal pattern by monthly analyses in incidence or proportion of reported snakebites with myokymia. All four of the reviewed cases with myokymia of the shoulders were intubated and none without it were intubated. A review of four consecutive years of data revealed no pattern to correlate the incidence of fasciculations with the month. The development of respiratory failure associated with myokymia, sometimes despite antivenom, is a newly reported occurrence. Clinicians are reminded to monitor closely airway and inspiratory capacity in patients with severe myokymia.

2017-01-01

Cushing's syndrome due to ectopic adrenocorticotropic hormone production from adrenal medullary lesions has occasionally been described. We retrospectively reviewed all 164 cases of Cushing's syndrome and 77 cases of pheochromocytomas during 10 years. Of all cases with Cushing's syndrome, only two cases (1.2 %) were due to ectopic adrenocorticotropic hormone production from adrenal medullary lesions (one case of pheochromocytoma and one case of adrenal medullary hyperplasia). Of all pheochromocytomas only the above-mentioned case (1.3 %) also gave rise to an ectopic adrenocorticotropic hormone syndrome. The clinical presentation of adrenocorticotropic hormone-secreting pheochromocytoma and adrenal medullary hyperplasia can be anything from mild to dramatic. These are rare conditions important to bear in mind in the workup of a patient with Cushing's syndrome or with pheochromocytoma. The identification of ectopic adrenocorticotropic hormone secretion from adrenal medullary lesions can be life-saving.

Objectives The aim of this retrospective cohort study was to examine whether exposure to early childhood protein-energy malnutrition (ECPEM) is related to worsened periodontal status in the permanent dentition during adolescence. Design A trained clinician/researcher examined the periodontal status of 96 persons aged 12–19 living in rural Haiti using WHO diagnostic criteria (Community Periodontal Index, WHO 1997). Malnutrition data of the study participants had been collected during the years 1988–1993 by a nongovernmental organization. We compared those who had been malnourished in early childhood, based on z-scores for anthropomorphic data collected during the first 5 years of life, with those who had not been malnourished, regarding mean Community Periodontal Index (CPI) score, controlling for age, sex, socioeconomic status, and smoking. Results Overall, 57.3% of the participants demonstrated a CPI score of 3 or greater in at least one sextant. ECPEM was independently and positively related to mean CPI score, when controlling for sex and smoking. Conclusions More than half of these young Haitians demonstrated CPI scores of 3 or greater, and ECPEM was related to poorer periodontal status, as measured by CPI, in the permanent dentition.

Data regarding length of stay (LOS) in a rehabilitation programme after traumatic brain injury (TBI) are limited. The goal of this study was to examine the effect of LOS and disability on outcome following TBI. Records from patients in a multidisciplinary rehabilitation programme at least 3 months after TBI were analysed retrospectively to study the influence of LOS on functional outcome at different levels of disability. Functional status was determined by the Mayo-Portland Adaptability Inventory (MPAI) and the Community Integration Questionnaire (CIQ). Patients were further grouped by time since injury of 3-12 months or over 1 year. Those with a mild and moderate disabilities and over 1 year chronicity showed improvements after 90 days of rehabilitation. Patients with a severe disability and over 1 year chronicity required at least 180 days to show improvements. Moderately and severely disabled patients with an injury chronicity of 3-12 months showed improvements in the MPAI after 90 days. However, further improvement was observed after 180 days in the severely disabled group. Results suggest that both, level of disability and injury chronicity, should be considered when determining LOS. Data also show an association between LOS and changes in the MPAI and CIQ.

Studies published from centers across India have reported different and contradicting patterns of glomerular disease. In this retrospective study, we report our experience from a Tertiary Care Center in Northwest India. A total of 702 renal biopsies performed between 2008 and 2013 were reviewed of which 80 were excluded from the study because of having insufficient records or if the biopsies were taken from an allograft. The study included 411 males (66.1 %) and 211 females (33.9%) with an age range of 12-70 years (mean 30.34 ± 7.04 years). Majority of the biopsies (93.9%) showed some form of glomerulonephritis (GN), either primary (79.4%) or secondary glomerular disease (SGD) (14.5%). Minimal change disease (MCD) was the most common type of primary GN (26.5% of primary GN), followed by membranous nephropathy (MN; 18.8%) and focal and segmental glomerulosclerosis (FSGS; 13.2%). Lupus nephritis (LN) was the most frequent SGD (52.2% of secondary GN). Amyloidosis was found in 41.1% and diabetic glomerulosclerosis in 4.4%. LN was also the second most common diagnosis in females after MCD, seen in 19.4% of females. MCD followed by membranoproliferative GN and diffuse proliferative GN were the most common entities in individuals <20 years of age. In the 20-39 years age group, MN was the most common pathology seen. MN was again the most common pathology seen in patients aged above 40 years followed by amyloidosis and FSGS. In this study, MCD was the most common primary GN observed overall from this part of India. MN was the most common GN in individuals above 20 years of age presenting with the nephrotic syndrome. The geographical and regional differences in the pattern of GNs point to the necessity of having a central biopsy registry.

Önal, Gülsüm; Civaner, M. Murat

2015-01-01

Background: In 2004, Patient Rights Units were established in all public hospitals in Turkey to allow patients to voice their complaints about services. Aims: To determine what violations are reflected into the complaint mechanism, the pattern over time, and patients’ expectations of the services. Study Design: Descriptive study. Methods: A retrospective study performed using the complaint database of the Istanbul Health Directorate, from 2005 to 2011. Results: The results indicate that people who are older than 40 years, women, and those with less than high school education are the most common patients in these units. A total of 218,186 complaints were filed. Each year, the number of complaints increased compared to the previous year, and nearly half of the applications were made in 2010 and 2011 (48.9%). The three most frequent complaints were “not benefiting from services in general” (35.4%), “not being treated in a respectable manner and in comfortable conditions” (17.8%), and “not being properly informed” (13.5%). Two-thirds of the overall applications were found in favour of the patients (63.3%), and but this rate has decreased over the years. Conclusion: Patients would like to be treated in a manner that respects their human dignity. Educating healthcare workers on communication skills might be a useful initiative. More importantly, health policies and the organisation of services should prioritise patient rights. It is only then would be possible to exercise patient rights in reality. PMID:25759767

Patients with cerebral palsy (CP) frequently present with scoliosis; however, the pattern of curve progression is difficult to predict. We aimed to clarify the natural course of the progression of scoliosis and to identify scoliosis predictors. This was a retrospective, single-center, observational study. Total of 92 CP patients from Asahikawasou Ryouiku Iryou Center in Okayama, Japan were retrospectively analyzed. Cobb angle, presence of hip dislocation and pelvic obliquity, and Gross Motor Function Classification System (GMFCS) were investigated. Severe CP was defined as GMFCS level IV or V. The mean observation period was 10.7 years. Thirtyfour severe CP patients presented with scoliosis and were divided into 3 groups based on their clinical courses: severe, moderate and mild. The mean Cobb angles at the final follow-up were 129°, 53°, and 13° in the severe, moderate, and mild groups, respectively. The average progressions from 18 to 25 years were 2.7°/year, 0.7°/year, and 0.1°/year in the severe, moderate, and mild curve groups, respectively. We observed the natural course of scoliosis and identified 3 courses based on the Cobb angle at 15 and 18 years of age. This method of classification may help clinicians predict the patients' disease progression.

The purpose of this retrospective cohort study was to analyze the association between income level and health care access in Japan. Data from a total of 222,259 subjects (age range, 0–74 years) who submitted National Health Insurance claims in Chiba City from April 2012 to March 2014 and who declared income for the tax period from January 1 to December 31, 2012 were integrated and analyzed. The generalized estimating equation, in which household was defined as a cluster, was used to evaluate the association between equivalent income and utilization and duration of hospitalization and outpatient care services. A significant positive linear association was observed between income level and outpatient visit rates among all age groups of both sexes; however, a significantly higher rate and longer period of hospitalization, and longer outpatient care, were observed among certain lower income subgroups. To control for decreased income due to hospitalization, subjects hospitalized during the previous year were excluded, and the data was then reanalyzed. Significant inverse associations remained in the hospitalization rate among 40–59-year-old men and 60–69-year-old women, and in duration of hospitalization among 40–59 and 60–69-year-olds of both sexes and 70–74-year-old women. These results suggest that low-income individuals in Japan have poorer access to outpatient care and more serious health conditions than their higher income counterparts. PMID:26978270

Limited data is available on the feasibility of high-dose chemotherapy followed by autologous hematopoietic stem cell transplantation (AHSCT) in elderly patients over 70 years of age with non-Hodgkin's lymphoma (NHL). In the setting of the Société Française de Greffe de Moelle et de Thérapie Cellulaire (SFGM-TC) group, we retrospectively analyzed 81 consecutive patients with NHL over 70 years of age who received AHSCT. The median age at AHSCT was 72.3 years [70-80]. Patients' were diagnosed with diffuse large B-cell lymphoma (n=40), follicular lymphoma (n=16), mantle cell lymphoma (n=15), T-cell lymphoma (n=5), and other (n=5). Hematopoietic Cell Transplantation Comorbidity Index (HCT-CI) was 0 in 73% of patients. Main conditionings were BEAM (Carmustine-Etoposide-Cytarabine-Melphalan, n=61) and melphalan alone (n=14). Median delays to reach 0.5×10⁹/L neutrophils and 20 × 10(9)/L platelets were of 12 [9-76] days and 12 [0-143] days, respectively. One hundred day and one year cumulative incidence of NRM was 5.4% and 8.5%, respectively. The main cause of death remains relapse. In conclusion, this study revealed that AHSCT seemed to be acceptable in patients over 70 years of age with NHL. Patient age is not a limiting factor if clinical condition is adequate.

Although heart failure (HF) is recognized as a leading contributor to healthcare costs and a significant economic burden worldwide, studies of HF-related costs in South Korea are limited. This study aimed to estimate HF-related costs per Korean patient per year and per visit. This retrospective cohort study analyzed data obtained from six hospitals in South Korea. Patients with HF who experienced ≥one hospitalization or ≥two outpatient visits between January 1, 2013 and December 31, 2013 were included. Patients were followed up for 1 year [in Korean won (KRW)]. Among a total of 500 patients (mean age, 66.1 years; male sex, 54.4%), the mean 1-year HF-related cost per patient was KRW 2,607,173, which included both, outpatient care (KRW 952,863) and inpatient care (KRW 1,654,309). During the post-index period, 22.2% of patients had at least one hospitalization, and their 1-year costs per patient (KRW 8,530,290) were higher than those of patients who had only visited a hospital over a 12-month period (77.8%; KRW 917,029). Among 111 hospitalized patients, the 1-year costs were 1.7-fold greater in patients (n=52) who were admitted to the hospital via the emergency department (ED) than in those (n=59) who were not (KRW 11,040,453 vs. KRW 6,317,942; p<0.001). The majority of healthcare costs for HF patients in South Korea was related to hospitalization, especially admissions via the ED. Appropriate treatment strategies including modification of risk factors to prevent or decrease hospitalization are needed to reduce the economic burden on HF patients. © Copyright: Yonsei University College of Medicine 2017

[Whole-body-CT in Severely Injured Children. Results of Retrospective, Multicenter Study with Patients from the TraumaRegsiter DGU®].

A fast and comprehensive diagnostic by means of whole-body CT has been shown to reduce mortality in the adult trauma population. Therefore whole-body CT seems to be the standard in adult trauma-patients. Due to the higher radiation exposure of whole-body CT the use of this diagnostic toll in pediatric trauma patients is still under debate. It is not yet clear if whole-body CT in children can increase the probability of survival. In a retrospective, multicenter study, we used the data recorded in the TraumaRegister DGU(®) to calculate the probability of survival according to the revised injury severity classification (RISC) and standardized mortality ratio (SMR). The SMR reflects the ratio of recorded to expected mortality. Included in the study were all children (1-15 years) and adults (16-50 years) with an Injury Severity Score (ISS)>9, who were directly admitted to the hospital from the scene of accident. We compared the groups of patients given whole-body CT or non-whole-body CT. Subgroup analysis was performed for children 1-9 years, children 10-15 years and adults. A total of 1,456 pediatric trauma patients (mean age 9.9 years) and 20,796 adults (mean age 32.7 years) were included in the study. In contrast to adult trauma patients, were the SMR in the whole-body CT group was significant lower; we observed no advantage for the whole-body CT in pediatric trauma patients. Due to the missing advantage of whole-body CT in the pediatric trauma population and the higher radiation exposure of whole-body CT a non-whole-body CT approach seems equivalent with a lower radiation exposure. © Georg Thieme Verlag KG Stuttgart · New York.

Combined anteroposterior spinal fusion with instrumentation has been used for many years to treat adult thoracolumbar/lumbar scoliosis. This surgery remains a technical challenge to spine surgeons, and current literature reports high complication rates. The purpose of this study is to validate a new hybrid technique (a combination of single-rod anterior instrumentation and a shorter posterior instrumentation to the sacrum) to treat adult thoracolumbar/lumbar scoliosis. This study is a retrospective consecutive case series of surgically treated patients with adult lumbar or thoracolumbar scoliosis. This is a retrospective study of 33 matched pairs of patients with adult scoliosis who underwent two different surgical procedures: a new hybrid technique versus a third-generation anteroposterior spinal fusion. Preoperative and postoperative outcome measures include self-report measures, physiological measures, and functional measures. In a retrospective case-control study, 33 patients treated with the hybrid technique were matched with 33 patients treated with traditional anteroposterior fusion based on preoperative radiographic parameters. Mean follow-up in the hybrid group was 5.3 years (range, 2-11 years), compared with 4.6 years (range, 2-10 years) in the control group. Operating room (OR) time, estimated blood loss, and levels fused were collected as surrogates for surgical morbidity. Radiographic parameters were collected preoperatively, postoperatively, and at final follow-up. The Scoliosis Research Society Patient Questionnaire (SRS-22r) and Oswestry Disability Index (ODI) scores were collected for clinical outcomes. Operating room time, EBL, and levels fused were significantly less in the hybrid group compared with the control group (p<.0001). The postoperative thoracic Cobb angle was similar between the hybrid and control techniques (p=.24); however, the hybrid technique showed significant improvement in the thoracolumbar/lumbar curves (p=.004) and the lumbosacral fractional curve (p<.0001). The major complication rate was less in the hybrid group compared with the control group (18% vs. 39%, p=.01). Clinical outcomes at final follow-up were not significantly different based on overall SRS-22r scores and ODI scores. The new hybrid technique demonstrates good long-term results, with less morbidity and fewer complications than traditional anteroposterior surgery select patients with thoracolumbar/lumbar scoliosis. This study received no funding. No potential conflict of interest-associated bias existed. Copyright © 2014 Elsevier Inc. All rights reserved.

Coelho, Marcelo Santos; Parker, Jeffrey M; Tawil, Peter Z

2016-06-01

The aim of this retrospective clinical study was to evaluate the location and treatment of second canals in mesiobuccal roots (MB2) of first and second maxillary molars in a predoctoral endodontic clinic by the graduating classes of 2008 to 2015. These results were compared to similar clinical studies. Included in the study were 368 root canal treatments performed by 310 third- and fourth-year dental students at one U.S. dental school. All cases were done under faculty supervision, and the students were instructed to use dental loupe magnification. Students' evaluation sheets were used to deteremine the total MB2 canals treated in first and second maxillary molars. The results showed that, overall, 72.55% of the teeth had an MB2 canal treated. The frequency was higher in first molars (75.91%) than in second molars (56.92%) (p<0.05). Third-year students were able to detect 39 MB2 canals in 57 maxillary molars (68.42%), while fourth-year students detected 228 MB2 canals in 311 teeth (73.31%) (p>0.05). Under proper supervision by experienced endodontists, these dental students were capable of treating MB2 canals in maxillary molars. The frequency of MB2 canals located and treated by dental students with the assistance of experienced professionals was higher in first than in second molars. No significant difference was found between third- and fourth-year students. The incidence of MB2 canals located and treated in this study was found to be similar to that in other clinical studies.

Objective Cross-sectional/retrospective data have indicated that individuals with body dysmorphic disorder (BDD) have high rates of suicidal ideation and attempts. However, no study, to the authors' knowledge, has prospectively examined suicidality in BDD. Method In the first prospective study of BDD's course, the authors examined suicidality in 185 subjects for up to 4 years. Results Suicidal ideation was reported by a mean of 57.8% of the subjects per year, and a mean of 2.6% attempted suicide per year. Two subjects (0.3% per year) completed suicide. Conclusions Individuals with BDD have high rates of suicidal ideation and attempts. The completed suicide rate is preliminary but suggests that the rate of completed suicide in BDD is markedly high.

To estimate patients enrolling on antiretroviral therapy (ART) over time; describe trends in baseline characteristics; and compare immunological response, loss to follow-up (LTFU), and mortality by three age groups (25-39, 40-49 and ≥50 years). A retrospective observation cohort study. This study used routine ART data from two public clinics in Lilongwe, Malawi. All HIV-infected individuals, except pregnant or breastfeeding women, aged ≥ 25 years at ART initiation between 2006 and 2015 were included. Poisson regression models estimated risk of mortality, stratified by age groups. Of 37,378 ART patients, 3,406 were ≥ 50 years old. Patients aged ≥ 50 years initiated ART with more advanced WHO clinical stage and lower CD4 cell count than their younger counterparts. Older patients had a significantly slower immunological response to ART in the first 18 months on ART compared to patients aged 25-39 years (p = 0.04). Overall mortality rates were 2.3 (95% confidence Interval (CI) 2.2-2.4), 2.9 (95% CI 2.7-3.2) and 4.6 (95% CI 4.2-5.1) per 100 person-years in patients aged 25-39 years, 40-49 years and 50 years and older, respectively. Overall LTFU rates were 6.3 (95% CI 6.1-6.5), 4.5 (95% CI 4.2-4.7), and 5.6 (95% CI 5.1-6.1) per 100 person years among increasing age cohorts. The proportion of patients aged ≥ 50 years and newly enrolling into ART care remained stable at 9% while the proportion of active ART patients aged ≥50 years increased from 10% in 2006 to 15% in 2015. Older people had slower immunological response and higher mortality. Malawi appears to be undergoing a demographic shift in people living with HIV. Increased consideration of long-term ART-related problems, drug-drug interactions and age-related non-communicable diseases is warranted.

Several patients with new onset brain tumors present to the Emergency Department (ED) complaining for new symptoms. Although information exists on symptom prevalence in the entire population of patients with brain tumors, little is known about the clinical presentation in ED. This retrospective study was planned to investigate clinical presentation and epidemiology of brain tumors firstly diagnosed in a large urban ED throughout a 10-year period. All medical records of patients aged ≥18 years, discharged from our ED with a diagnosis of brain tumor were retrieved from the electronic hospital database during a 10-year period (2006 to 2015). The records were reassessed for selecting only brain tumors firstly diagnosed in the ED. The symptoms at presentation were divided in six categories: (I) headache; (II) seizures; (III) focal signs; (IV) altered mental status; (V) nausea/vomiting/dizziness; (VI) trauma. For all cases, the hospital record was retrieved, to obtain histologic classification of tumors. Patients with inflammatory neoformations were excluded from the study. Overall, 205 patients with firstly diagnosed brain tumor were identified among 870,135 ED visits (i.e., <1%). Glial tumors were the most frequent (50% of the entire sample). No significant differences were found between mean age of patients in the different histologically based groups (meningiomas 66±14; glioblastomas 65±16 years; metastases 66±13 years; other miscellaneous 66±19 years). Focal signs accounted for more than 50% of all presentation signs/symptoms. First presentation of brain tumor in the ED is not a rare occurrence, so that the emergency physicians should be aware of this possibility.

Posterior Mandibular Ridge Resorption Associated with Different Retentive Systems for Overdentures: A 7-Year Retrospective Preliminary Study.

PubMed

Elsyad, Moustafa Abdou; Mohamed, Shahinaz Sayed; Shawky, Ahmad Fathalla

This retrospective study compared posterior mandibular residual ridge resorption with two different retentive mechanisms for overdentures after 7 years. A convenience sample of 18 edentulous men was assigned to one of two equal groups. Two implants were placed in the mandibular canine areas for each patient using the conventional two-stage surgical protocol, and the implants were splinted with a round bar 3 months later. New mandibular overdentures were then connected to the bars with clips (clip-retained overdentures, CR group) or resilient liners (resilient liner-retained overdentures, RR group). Posterior mandibular ridge resorption (PMRR) was recorded using proportional measurements and posterior area index (PAI) on panoramic radiographs taken immediately after overdenture insertion (T 0 ) and 7 years later (T 7 ). A linear regression model was used to verify the relationship between PAI and the following considerations: attachment type, age, initial mandibular ridge height, period of mandibular edentulism, number of previously worn dentures, and relining events. After 7 years, the RR group demonstrated a significantly (P = .014) higher change in PAI (0.11 ± 0.02) than the CR group (0.06 ± 0.04). The average PMRR for each mm of posterior mandibular ridge was 0.79 mm (0.11 mm/year) in the CR group and 1.4 mm (0.2 mm/year) in the RR group. Attachment type, initial mandibular ridge height, and relining times were significantly correlated with change in the PAI (P = .004, P = .035, and P = .045, respectively). Within the limitations of this preliminary study's design, it was observed that following a 7-year period of use, resilient liner attachments for bar/implant-retained overdentures appear to be associated with greater posterior mandibular ridge resorption when compared to clip attachments.

Study Design: Retrospective review. Objective: The aim of our study was to quantify the frequency of complications associated with recombinant human bone morphogenetic protein 2 (rhBMP-2) use in anterior lumbar interbody fusion (ALIF). Methods: The orthopedic subset of the Medicare database (PearlDiver) was queried for this retrospective cohort study using International Statistical Classification of Diseases 9 (ICD-9) and Current Procedure Terminology (CPT) codes for ALIF procedures with and without rhBMP-2 between 2005 and 2010. Frequencies of complications and reoperations were then identified within 1 year from the index procedure. Complications included reoperations, pulmonary embolus, deep vein thrombosis, myocardial infarction, nerve-related complications, incision and drainage procedures, wound, sepsis, pneumonia, urinary tract infections, respiratory, heterotopic ossification, retrograde ejaculation, radiculopathy, and other medical complications. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the statistical significance. Results: We identified a total of 41 865 patients who had an ALIF procedure. A total of 14 384 patients received rhBMP-2 while 27 481 did not. Overall, 6016 (41.8%) complications within 1 year from surgery were noted within the group who received rhBMP-2 and 12 950 (47.1%) complications within 1 year from surgery were recorded in those who did not receive rhBMP-2 (OR = 0.81, CI = 0.77-0.84). Overall, exposure to rhBMP-2 was associated with significantly decreased odds of complications with exception to reoperation rates (0.9% rhBMP-2 vs 1.0% no rhBMP-2; OR = 0.88, CI = 0.71-1.09) and radiculopathy (4.4% rhBMP-2 vs 4.3% no rhBMP-2; OR = 1.02, CI = 0.93-1.13). Conclusions: The use of rhBMP-2 in patients undergoing ALIF procedure was associated with a significantly decreased rate of complications. Further studies are needed to elucidate a true incidence of complication. PMID:28507884

Late-onset vitiligo, defined as being aged 50 years and above at the point of clinical onset, remains poorly characterized till now. This study aims to describe the clinical characteristics and treatment response of patients with late-onset vitiligo. We retrospectively reviewed the case records of all patients diagnosed with late-onset vitiligo, from January 1, 2010 to December 31, 2014. Information obtained included patient demographics, characteristics of vitiligo and treatment responses. Of the 3128 patients diagnosed with vitiligo over the 5-year period, 461 (14.7%) had late-onset disease. The study had more females (n = 260, 56.4%) than males, with an average onset age of 59.4 ± 7.4 years. Majority of patients were Chinese (n = 308, 66.8%) and 45 (9.8%) patients had an associated autoimmune disease. Focal vitiligo, defined as the localized presence of depigmented patches, was most common (n = 209, 45.3%). Treatment response was evaluated in 359 patients, of which 216 received monotherapy (topical creams: n = 210, 97.2%; phototherapy: n = 6, 2.8%) and 143 received both modalities. Fifty six (15.6%) patients received oral steroids. Patients who were treated with both topical creams and phototherapy yielded better clinical responses compared to those on monotherapy (P < 0.001) with 56.6% (n = 81) of them achieving good epidermal repigmentation, defined as >50% return of pigmentation compared to baseline (vs. n = 66, 30.6% in the monotherapy group). The choice of phototherapy (targeted, narrowband ultraviolet B or psoralen + ultraviolet A) did not significantly affect clinical response (P = 0.774). This study is limited by its retrospective nature, the nonstandardized documentation resulting in the inability to determine disease progression and associated metabolic comorbidities and also by the gradual loss to follow-up of patients. Late-onset vitiligo is not uncommon and tends to be of the focal vitiligo subtype. Nonsegmented vitiligo is more prevalent than segmental vitiligo. Combination therapy with topical medications and phototherapy is superior to monotherapy.

The purpose of this study was to analyze the impact of intra-cavitary brachytherapy (ICBT) as boost radiation after external beam radiotherapy (EBRT) in carcinoma of the external auditory canal and middle ear (EACMA): A retrospective analysis. A retrospective study of 18 patients with carcinoma of the EACMA who were treated with a curative intent from the year 1998 to 2010 was carried out. The age of the patients ranged from 25 years to 67 years. There were 11 male patients (61.1%) and 7 female patients (38.9%). A total of 15 (88.2%) patients were treated with curative radiation alone after a biopsy and two patients received post-operative radiation therapy. The patients were initially treated with EBRT with cobalt 60 machine up to 60-64 Gy. In our department, all the patients who were technically suitable for ICBT received an ICBT boost. The overall survival (OS) in these patients ranged from 7 months to 151 months (9 out of 17 patients, no evidence of disease 53%). The OS in patients treated with a combination of EBRT with ICBT was (8 out of 11) 72.7%, P value statistically significant (P value: 0.0024). The multivariate analysis shows statistically significant difference only for patients who got an ICBT boost (P Value: 0.020). ICBT as a boost after EBRT has got a positive impact on the OS. In conclusion, our results demonstrate that radical radiation therapy (EBRT and ICBT) is the treatment of choice for stage T2, carcinoma of EACMA.

Experiences in adolescence may have a lasting impact on adulthood. The objective of this study is to evaluate the association between adolescent (12-18 years of age) volunteerism with the incidence of illegal behaviors, arrests, and convictions in adulthood (>18 years of age). We conducted a retrospective cohort study using secondary data from the National Longitudinal Study of Adolescent to Adult Health. Students from grades 7-12 were recruited in 1994-1995 (n = 20,745), and then followed in 2001-2002 (n = 14,322) and in 2008-2009 (n = 12,288). In 2000-2001, participants were retrospectively asked about their volunteering experience from 12 to 18 years of age. Consequently, participants were divided into non-volunteers, self-volunteers, adult-required volunteers, and court-ordered volunteers. Groups were compared for rates of illegal behaviors, arrest, and convictions in adulthood (>18 years of age) using weighted generalized linear mixed negative binomial models while accounting for sampling design. Relative to non-volunteers, self-volunteers reported 11 % fewer illegal behaviors (RR: 0.89, 95 % CI: 0.80, 0.99), 31 % fewer arrests (RR: 0.69, 95 %: 0.57, 0.85), and 39 % fewer convictions (RR: 0.61, 95 % CI: 0.47, 0.79) by age 18-28 years, and 28 % fewer illegal behaviors, 53 % fewer arrests, and 36 % fewer convictions by age 24-34. In comparison the adult-required volunteers also reported fewer arrests and convictions; however, they reported more illegal behaviors than the non-volunteers. The court-ordered volunteers reported higher rates of criminal involvement than the non-volunteers, throughout. This study suggests that volunteering in adolescence may reduce crime involvement in adulthood.

Mechanical ventilation support can be the main source of ventilator-associated pneumonia (VAP). VAP is a serious infection that may be associated with dangerous gram-negative bacteria mainly, and it leads to an increase in the mortality in the intensive care unit (ICU). Imipenem is one of the strongest antibiotics now available for treating VAP which is associated with gram-negative and gram-positive bacteria, and it belongs to beta-lactam antibiotic group (carbapenem). This study tried to investigate the efficacy of imipenem against VAP when it was infused within 180 min versus the efficacy when it was infused within 30-60 min. This study was conducted in main ICU in general hospital which consists of surgical and medical beds within 2 years. One hundred and eighty-seven patients were enrolled on it. This study is a retrospective cohort which was conducted within 2 years. The efficacy of imipenem which was administered by intermittent infusion (30-60 min) within first year was compared with the efficacy of imipenem which was administered by extended infusion (180 min) within second year in the field of VAP curing and cost reduction. All data were collected retrospectively from patient medical files and were statistically analyzed by SPSS version 20. The study was designed to measure clinical and cost reduction outcomes, mortality and hospital stay. The results indicated that there is a significant decrease in mortality, number of recurrent infection, and ICU stay length, and the number of mechanical ventilator days was associated with extended imipenem infusion during the second year of the study. The use of imipenem with extended infusion over 3 hours enhances its clinical outcomes in the treatment of VAP.

Background Long-term employment trajectories of young problem drinkers are poorly understood. Methods We constructed retrospective labour market participation histories at ages 18–34 of 64 342 persons born in 1969–1982. Beginning from the year of each subject’s 18th birthday, we extracted information from the records of Statistics Finland on educational attainment, main type of economic activity, months in employment, and months in unemployment for a minimum of seven years (range 7–16 years). We used information on the timing of alcohol-related hospitalizations and deaths in the same period to define problem drinkers with early onset limited course, early onset persistent course, and late onset problem drinking. Results Early onset limited course problem drinkers improved their employment considerably by age, whereas early onset persistent problem drinkers experienced a constant decline in their employment by age. From the age of 18 to 34, early onset persistent problem drinkers were in employment merely 12% of the time, in comparison with 39% among the early onset limited course problem drinkers, and 58% among the general population. Conclusions These results indicate that young adults who were retrospectively defined as having early onset persistent course problem drinking were extensively marginalized from the labour market early on during their life course, and that their employment trajectory was significantly worse compared to other problem drinkers.

Pigment epithelial detachment (PED) may be seen in all stages of age-related macular degeneration (ARMD) and may lead to poor prognosis. In this study, we retrospectively examined the effect of anti-VEGF treatments in ARMD patients with vascularized PED. Medical records of 15 patients with PED secondary to ARMD were reviewed retrospectively. The diagnosis of PED was made with fundoscopy, fundus fluorescein angiography and optical coherence tomography. Patients were treated with intravitreal ranibizumab or/and bevacizumab and followed up for a minimum of one year. PED height and best corrected visual acuity (BCVA) was obtained before the first intravitreal anti-VEGF injection and again at the 1st, 3rd, 6th and 12th month after the injection. The mean baseline BCVA was 0.71 ± 0.48 logarithm of the minimal angle of resolution (logMAR) unit and the mean baseline PED height was 361 ± 153 µ. The mean injection count per eye was 3.9 ± 2.9. There was a significant reduce in mean PED height (247 ± 177 µ) also in 2 eyes PED completely resolved at the end of the follow up period. The mean BCVA at 12th month (0,69 ± 0,37) were not different from the baseline record. This retrospective case series showed that intravitreal anti-VEGF therapy preserved vision and reduced PED height in PED patients in a one-year follow-up period.

Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma encountered in childhood and adolescence. Early diagnosis of pediatric cases is critical to improving outcomes, especially when socioeconomic status and geographical access to specialist services can reduce opportunities for early cancer detection and treatment. The objective of this study is to determine factors that can delay referral and treatment in specialist pediatric oncology center upon our population specificities. This retrospective study involved 31 children between 2003 and 2013. Children affected by histologically confirmed RMS occurring as a primary lesion in the orofacial area were included. The median age was 8 ± 4.22 years (range: 3 months - 15 years). The male to female ratio was 1.8:1. Most of the patients had advanced stage disease at presentation (81.7% group had 3-4 pretreatment staging) with parameningeal involvement in 80.6% of the cases. The 2-year event-free survival rate was 17.7 ± 7.8% for all the patients. Delay of admission to our unit and abandonment of treatment seem to be important factors for the dismal prognosis. Patient's location, socioeconomic status and health care coverage have had an impact on longer delays in seeking care and on follow-up. More studies are needed for implementation of a better management practices and a better supportive care upon specificities of our population.

The global burden from cancer is rising, especially as low-income countries like Bangladesh observe rapid aging. So far, there are no comprehensive descriptions reporting diagnosed cancer group that include hematological malignancies in Bangladesh. This was a multi-center hospital-based retrospective descriptive study of over 5000 confirmed hematological cancer cases in between January 2008 to December 2012. Morphological typing was carried out using the "French American British" classification system. A total of 5013 patients aged between 2 to 90 years had been diagnosed with malignant hematological disorders. A 69.2% were males (n=3468) and 30.8% females (n=1545), with a male to female ratio of 2.2:1. The overall median age at diagnosis was 42 years. Acute myeloid leukemia was most frequent (28.3%) with a median age of 35 years, followed by chronic myeloid leukemia with 18.2% (median age 40 years), non-Hodgkin lymphoma (16.9%; median age 48 years), acute lymphoblastic leukemia (14.1%; median age 27 years), multiple myeloma (10.5%; median age 55 years), myelodysplastic syndromes (4.5%; median age 57 years) and Hodgkin's lymphoma (3.9%; median age 36 years). The least common was chronic lymphocytic leukemia (3.7%; median age 60 years). Below the age of 20 years, acute lymphoblastic leukemia was predominant (37.3%), followed by acute myeloid leukemia (34%). Chronic lymphocytic leukemia and multiple myeloma had mostly occurred among older patients, aged 50-over. For the first time, our study presents the pattern and distribution of diagnosed hematological cancers in Bangladesh. It shows differences in population distributions as compared to other settings with possibly a lower presence of non-Hodgkin lymphoma. There might be under-reporting of affected women. Further studies are necessary on the epidemiology, genetics and potential environmental risk factors within this rapidly aging country.

The present study was designed to assess possible relationships between deterioration of the glycated hemoglobin (HbA1c)-lowering effects in dipeptidyl peptidase-4 inhibitor (DPP4i) monotherapy and macronutrient intake among individuals with type 2 diabetes. Type 2 diabetes patients who began and continued DPP4i monotherapy without any prescription change for 1 year were retrospectively stratified into two groups: (i) patients who maintained their HbA1c levels during the 0.5- to 1-year period after DPP4i initiation (group A, ΔHbA1c [1-0.5 year] <0.4%, n = 53); and (ii) those whose HbA1c levels increased [group B, ΔHbA1c (1-0.5 year] ≥0.4%, n = 10). Group B had significantly higher ΔHbA1c (1-0.5 year), Δbodyweight (1-0.5 year) and fat intake, especially of saturated and monounsaturated fats; the carbohydrate and protein intake were similar between groups. Multiple regression analyses showed that fat intake, especially saturated fat intake, was significantly correlated with ΔHbA1c (1-0.5 year). Thus, dietary habits, especially saturated fat intake, might well contribute to deterioration of the HbA1c-lowering effects in DPP4i monotherapy. © 2017 The Authors.

Androgen receptor defects affect the regulation of the gonadotropic axis. However, little is known about the timing of pubertal maturation in complete androgen insensitivity syndrome (CAIS). To evaluate growth, skeletal maturation and gonadotropin and sex steroid secretion in patients with CAIS and intact gonads at puberty. Clinical, auxological and hormonal evaluation of 9 patients with CAIS from birth up to 17 years of age, prior to gonadectomy, in a single institution, retrospective study. Breast development occurred at a median age of 11.1 years, thumb sesamoid appeared at 11.5 years, and peak height velocity at 12.3 years, all consistent with average female values. However, median adult male height (+1.2 SDS) was closer to the patients' male target height (-0.3 SDS). Plasma testosterone levels rose early compared to normal boys. LH (basal and GnRH-stimulated) increased rapidly, above normal male values, in early puberty. This retrospective evaluation of a limited number of cases with a heterogeneous pattern of follow-up suggests that patients with CAIS may enter puberty at an age closer to female standards. These results imply a major role of direct androgen action, in utero or in early life, in determining the pattern of pubertal gonadotropin maturation.

ABSTRACT Objective: To evaluate using tomographic study the thickness of the cranial board at the insertions points of the cranial halo pins in adults Methods: This is a retrospective, cross-sectional, descriptive analysis of Computed Tomography (CT) scans of adult patients' crania. The study included adults between 20 and 50 years without cranial abnormalities. We excluded any exam with cranial abnormalities Results: We analyzed 50 CT scans, including 27 men and 23 women, at the original insertion points and alternative points (1 and 2 cm above the frontal and parietal bones). The average values were 7.4333 mm in the frontal bone and 6.0290 mm in the parietal bone Conclusion: There was no statistically significant difference between the classical and alternative points, making room for alternative fixings and safer introduction of the pins, if necessary.Level of Evidence II, Retrospective Study.

The impact of implementing the European Working Time Directive (EWTD) and the consequent reduction in hours of work has led to concerns about training. This retrospective study compared total caseload, obstetric caseload, out-of-hours caseload and supervision levels of trainee anaesthetists in one region of the UK (Wessex) before and after the implementation of EWTD compliant rotas. Anaesthetic trainee logbooks submitted at the annual Record of In-Training Assessment were compared between the years 1999 and 2006. The logbook data was divided into two groups, group A (13-h shift) and group B (24-h on-call rota). There was no difference in total caseload, obstetric caseload or supervision. Out-of-hours caseload was greater in group A (p < 0.01).

Our aim was to retrospectively investigate the frequency and outcome of large-volume iodinated contrast medium (CM) extravasation in our institution and to compare our management protocol to current practice. Institutional review board approval was obtained, and informed consent was waived because the study was retrospective. From January 2008 to September 2016, radiological examinations with intravenous non-ionic iodinated CM administration were performed in 67,129 patients. Contrast medium extravasation events on CT scans and intravenous pyelograms but not on angiograms were included. All data were collected prospectively and stratified according to age, injection method (manual vs auto-injection), prevention of extravasation by various means (including intercom alarm), management of extravasation (routine application of silver sulfadiazine ointment, clobetasol propionate cream, and damp gauze at room temperature), etc. RESULTS: The incidence of large-volume CM extravasation was very low (0.04% [27/67,129] overall; 0.03% related to manual injection [age range, 59-92 years; mean, 75.4 years], and 0.045% related to auto-injection [age range, 36-86 years; mean, 65.8 years]). The CM extravasation volume in majority of patients was 20-40 ml in 5 of 9 patients (55.6%) in the manual injection group and 14 of 18 (77.8%) in the auto-injection group. Swelling and pain were the most common symptoms. No patient developed severe signs or needed surgical intervention. Results show a very low incidence of large-volume CM extravasation without severe complications or sequelae. The casual effect between our protocols and good outcome cannot be scrutinised thoroughly because the study lacks a control group and is retrospective. • The incidence of large-volume contrast medium extravasation (≥20 ml) was 0.04%. • No patient needed surgical intervention, and most recovered within 7 days. • Each element of our management protocol contributed to good outcome.

A multicenter, retrospective, cohort study was conducted in the Netherlands. The aim was to evaluate whether surgical volume of laparoscopic hysterectomies (LHs) performed by proven skilled gynecologists had an impact on the conversion rate from laparoscopy to laparotomy. In 14 hospitals, all LHs performed by 19 proven skilled gynecologists between 2007 and 2010 were included in the analysis. Surgical volume, conversion rate and type of conversion (reactive or strategic) were retrospectively assessed. To estimate the impact of surgical volume on the conversion rate, logistic regressions were performed. These regressions were adjusted for patient's age, Body Mass Index (BMI), ASA classification, previous abdominal surgery and the indication (malignant versus benign) for the LH. During the study period, 19 proven skilled gynecologists performed a total of 1051 LHs. Forty percent of the gynecologists performed over 20 LHs per year (median 17.3, range 5.4-49.5). Conversion to laparotomy occurred in 5.0% of all LHs (53 of 1051); 38 (3.6%) were strategic and 15 (1.4%) were reactive conversions. Performing over 20 LHs per year was significantly associated with a lower overall conversion rate (OR adjusted 0.43, 95% CI 0.24-0.77), a lower strategic conversion rate (OR adjusted 0.32, 95% CI 0.16-0.65), but not with a lower reactive conversion rate (OR adjusted 0.96, 95% CI 0.33-2.79). A higher annual surgical volume of LHs by proven skilled gynecologists is inversely related to the conversion rate to laparotomy, and results in a lower strategic conversion rate.

Introduction: The Ottawa Knee Rule is a validated clinical decision rule for determining whether knee radiographs should be obtained in the setting of acute knee trauma. The objectives of this study were to assess physician knowledge of, barriers to implementation of, and compliance with the Ottawa Knee Rule in academic emergency departments (EDs), and evaluate whether patient characteristics predict guideline noncompliance. Methods: A 10 question online survey was distributed to all attending ED physicians working at three affiliated academic EDs to assess knowledge, attitudes and self-reported practice behaviors related to the Ottawa Knee Rule. We also performed a retrospective ED record review of patients 13 years of age and older who presented with acute knee trauma to the 3 study EDs during the 2009 calendar year, and we analyzed ED records for 19 variables. Results: ED physicians (n = 47) correctly answered 73.2% of questions assessing knowledge of the Ottawa Knee Rule. The most commonly cited barriers to implementation were “patient expectations” and system issues, such as “orthopedics referral requirement.” We retrospectively reviewed 838 records, with 260 eligible for study inclusion. The rate of Ottawa Knee Rule compliance was retrospectively determined to be 63.1%. We observed a statistically significant correlation between Ottawa Knee Rule compliance and patient age, but not gender, insurance status, or provider type, among others. Conclusion: Compliance with the Ottawa Knee Rule among academic ED healthcare providers is poor, which was predicted by patient age and not other physician or patient variables. Improving compliance will require comprehensive educational and systemic interventions. PMID:23251717

Psoriatic alopecia - fact or fiction? A clinicohistopathologic reappraisal.

Silva, Claudine Yap; Brown, Katherine L; Kurban, Amal K; Mahalingam, Meera

2012-01-01

The incidence of psoriatic alopecia in psoriatic patients is underwhelming, given the prevalence of psoriasis in the North American population. Recently, a 60-year-old Albanian female, lacking a significant medical history for psoriasis, presented to our clinic with a 1-year history of "dandruff" associated with itch, hair thinning, and histopathologic evidence consistent with prior reports of "psoriatic alopecia." The absence of preceding or concomitant psoriasis suggests that the patient's alopecia is an antecedent manifestation of psoriasis, thus prompting this retrospective study to ascertain better the relationship between alopecia and psoriasis. We performed a retrospective review of 33 scalp biopsies on 31 patients having histopathologic diagnosis of psoriasis belonging to 31 patients seen between 2007 and 2010. Alopecia was a presenting feature in 48% of cases with definitive clinical and/or histopathologic diagnosis of psoriasis (scale crust with neutrophils, psoriasiform epidermal hyperplasia, and hypogranulosis). The most common follicular-related changes were infundibular dilatation (87%) followed by perifollicular fibrosis (77%), perifollicular lymphocytic inflammation (68%), thinning of the follicular infundibulum (55%), and fibrous tracts (28%). Of interest, sebaceous glands were absent in 60% and atrophic in 25% of cases. While a major limitation of this study is that it is a retrospective one, given that these changes are common to varying degrees in all lymphocytic scarring alopecias, we posit that psoriatic alopecia likely represents a secondary clinical change to a primary process and is not a unique histopathologic entity. A prospective study with a control group that includes lymphocytic scarring alopecias from non-psoriatic patients is required to support our findings.

Various techniques have been reported for the treatment of chronic acromioclavicular (AC) joint separation. The purpose of this study was to evaluate the results of surgical construction of coracoclavicular ligament using coracoid process transfer augmented with a hook plate fixation. Twenty-one patients treated with coracoid process transfer augmented with a hook plate fixation for chronic type III and V AC injuries were retrospectively analysed in 2003-2009. The age of the patients ranged from 23 to 58 years with an average age of 41.6 years. The patients were followed up clinically and radiographically, with an average of 33.0 months. Functional status and the ability to return to work were recorded during follow-up. Constant score and visual analogue scale (VAS) for pain were measured. The mean Constant score has increased from 70.9 points preoperatively to 90.7 points at follow-up. The mean VAS score has decreased from 4.7 preoperatively to 1.2 at follow-up. The average abduction was 172°, forward flexion was 170° and external rotation was 56°. There were 10 excellent results, 10 good results and one fair result. All patients had resumed their job or returned to original sport activity at mean 3.7 months postoperatively. No reduction loss was observed after plate removal and the final follow-up. Despite retrospective nature of the study, the outcomes of surgical construction with process transfer augmented with hook plate fixation are promising for chronic type III and V AC injuries.

Sensitive outcome measures for disease progression are needed for treatment trials of Stargardt disease. To describe the yearly progression rate of atrophic lesions in the retrospective Progression of Stargardt Disease study. A multicenter retrospective cohort study was conducted at tertiary referral centers in the United States and Europe. A total of 251 patients aged 6 years or older at baseline, harboring disease-causing variants in ABCA4 (OMIM 601691), enrolled in the study from 9 centers between August 2, 2013, and December 12, 2014; of these patients, 215 had at least 2 gradable fundus autofluorescence images with atrophic lesion(s) present in at least 1 eye. Areas of definitely decreased autofluorescence (DDAF) and questionably decreased autofluorescence were quantified by a reading center. Progression rates were estimated from linear mixed models with time as the independent variable. Yearly rate of progression using the growth of atrophic lesions measured by fundus autofluorescence. A total of 251 participants (458 study eyes) were enrolled. Images from 386 eyes of 215 participants (126 females and 89 males; mean [SD] age, 29.9 [14.7] years; mean [SD] age of onset of symptoms, 21.9 [13.3] years) showed atrophic lesions present on at least 2 visits and were graded for 2 (156 eyes), 3 (174 eyes), or 4 (57 eyes) visits. A subset of 224 eyes (123 female participants and 101 male participants; mean [SD] age, 33.0 [15.1] years) had areas of DDAF present on at least 2 visits; these eyes were included in the estimation of the progression of the area of DDAF. At the first visit, DDAF was present in 224 eyes (58.0%), with a mean (SD) lesion size of 2.2 (2.7) mm2. The total mean (SD) area of decreased autofluorescence (DDAF and questionably decreased autofluorescence) at first visit was 2.6 (2.8) mm2. Mean progression of DDAF was 0.51 mm2/y (95% CI, 0.42-0.61 mm2/y), and of total decreased fundus autofluorescence was 0.35 mm2/y (95% CI, 0.28-0.43 mm2/y). Rates of progression depended on the initial size of the lesion. In Stargardt disease with DDAF lesions, fundus autofluorescence may serve as a monitoring tool for interventional clinical trials that aim to slow disease progression. Rates of progression depended mainly on initial lesion size.

Mucosal melanoma of the nasal cavity and paranasal sinuses is a rare and highly aggressive tumor. We report our experience over 20 years in management of this tumor. A retrospective study included 14 patients with primary sinonasal mucosal melanoma. The series comprised 8 male and 6 female patients, with a median age at diagnosis of 67 years. Staging on the American Joint Committee on Cancer classification of sinus cancer was 14% T2, 22% T3, 75% T4a and 7% T4b. All patients underwent primary surgical treatment; 71% received adjuvant external radiotherapy. Median recurrence-free interval was 28.7 months. Two- and 5-year overall survival was 43% and 32%, respectively. Median follow-up was 43 months. Mucosal melanomas of the nasal cavity and paranasal sinuses are very specific entities. Limited pathophysiological knowledge still precludes effective medium- and long-term management. Future treatment will probably be based on global adjuvant or neoadjuvant-targeted chemotherapy.

A number of long-distance running events are held each year in the United States; the Army Ten Miler (ATM) is one such race held annually in Washington, DC. The purpose of the present study was to retrospectively analyze medical encounters for runners participating in the ATM from 1998 to 2004. Of the estimated 91,750 runners over the 6-year period, 73,100 participants finished the race and were included in the data analysis. Demographic and injury data were collected from medical records of participants who received medical care while participating in the ATM, and injury-related factors were assessed. The most common category of injury was musculoskeletal (44%), followed by medical-related problems (27%) and dermatological injuries (27%). Similar to marathon and ironman races, ATM injury rates correlate with race-day temperature and dew point. Overall, however, the injury rates observed at the ATM were relatively low compared to those reported for longer distance events. Finally, we detail the medical coverage provided at the ATM, as this coverage could be used as a guide for similarly distanced races.

The impact of Luminex-detected HLA antibodies on outcomes after lung transplantation is unclear. Herein we have undertaken a retrospective study of pre-transplant sera from 425 lung transplants performed between 1991 and 2003. Pre-transplant sera, originally screened by complement-dependent cytotoxicity (CDC) assays, were retrospectively tested for the presence of HLA-specific antibodies using HLA-coated Luminex beads and C4d deposition on Luminex beads. The results were correlated with graft survival at 1 year. Twenty-seven patients were retrospectively identified as having been transplanted against donor-specific HLA antibodies (DSA) and 36 patients against non-donor-specific HLA antibodies (NDSA). DSA-positive patients had 1-year survival of 51.9% compared with 77.8% for NDSA and 71.8% for antibody-negative patients (p = 0.029). One-year survival of patients with complement-fixing DSA was 12.5% compared with 62.5% for non-complement-fixing DSA, 75.8% for non-complement-fixing NDSA and 71.8% for antibody-negative patients (p < 0.0001). DSA-positive patients with mean fluorescence intensity (MFI) >5,000 had 1-year survival of 33.3% compared with 71.4% for MFI 2,000 to 5000 and 62.5% for MFI <2,000 (p = 0.0046). Multivariable analysis revealed DSA to be an independent predictor of poor patient survival within 1 year (p = 0.0010, hazard ratio [HR] = 3.569) as well as complement-fixing DSA (p < 0.0001, HR = 11.083) and DSA with MFI >5,000 (p = 0.0001, HR = 5.512). Pre-formed DSA, particularly complement-fixing DSA, and high MFI are associated with poor survival within the first year after lung transplantation. Risk stratification according to complement fixation or MFI levels may allow for increased transplantation in sensitized patients.

What is the impact of the Belgian legislation (1 July 2003), coupling reimbursement of six assisted reproduction technology (ART) cycles per patient to restricted embryo transfer policy, on cumulative delivery rate (CDR) per patient? The introduction of Belgian legislation in ART had no negative impact on the CDR per patient based on realistic estimates within six cycles or 36 months. The introduction of Belgian legislation limiting the number of embryos for transfer resulted in a reduction of the multiple pregnancy rate (MPR) per cycle by 50%. A retrospective cohort study with a study group after implementation of the new ART legislation (July 2003 to June 2006) and the control group, before legislation (July 1999 to June 2002). CDR was compared in an academic tertiary setting between a study group after legislation (n = 795 patients, 1927 fresh and 383 frozen-thawed embryo transfer (FET) cycles) and a control group before legislation (n = 463 patients, 876 fresh and 185 FET cycles) within six cycles or 36 months, delivery or discontinuation of treatment. The CDR was estimated using life table analysis considering pessimistic, optimistic and realistic scenarios and compared after adjustment for confounding variables. In the realistic scenario we included information on embryo quality to define the prognosis of each patient discontinuing treatment. In the realistic scenario, CDR within 36 months was comparable (all ages, P = 0.221) in study group (60.8%) and control group (65.6%), as well as in different age groups (<36 years, P = 0.242; 36-39 years, P = 0.851; 40-42 years, P = 0.840). In the realistic scenario applied to six cycles, we found lower CDRs in the study group than in the control group within the two first cycles (all ages, P = 0.009; <36 years, P = 0.007) but no difference in CDRs between the two groups within the four subsequent cycles (all ages P = 0.232; <36 years, P = 0.198). The CDR within six cycles was 60 and 65.3% for study group and control group, respectively, for all ages, and 65.8 and 70.4%, respectively, in the subgroup younger than 36 years. In women ≥36 years, CDR within six cycles was comparable in both groups (36-39 years, 43% in study versus 44.4% in control group, P = 0.730; 40-42 years, 21% in study versus 23% in control group, P = 0.786). A retrospective cohort study design was the only way to study the impact of legislation on CDR. Owing to the retrospective nature of this analysis over a long period of time, our data are potentially influenced by improvements in techniques and therefore improved success rates in ART over time. This 'Belgian model' can now be considered for application worldwide in countries with the aim to reduce the main ART side effect (high MPR) and its associated costs without a negative effect on the main intended effect (high CDR). The authors have no conflict of interest to declare. No funding was obtained for this study.

Quantifying the function of the epiphyseal plate is worthwhile for the management of children with growth disorders. The aim of this retrospective study was to quantify the osteoblastic activity at the epiphyseal plate using the quantitative bone SPECT/CT. We enrolled patients under the age of 20 years who received Tc-99m hydroxymethylene diphosphonate bone scintigraphy acquired by a quantitative SPECT/CT scanner. The images were reconstructed by ordered subset conjugate-gradient minimizer, and the uptake on the distal margin of the femur was quantified by peak standardized uptake value (SUVpeak). A public database of standard body height was used to calculate growth velocities (cm/year). Fifteen patients (6.9-19.7 years, 9 female, 6 male) were enrolled and a total of 25 legs were analyzed. SUVpeak in the epiphyseal plate was 18.9 ± 2.4 (average ± standard deviation) in the subjects under 15 years and decreased gradually by aging. The SUVpeak correlated significantly with the age- and sex-matched growth velocity obtained from the database (R 2  = 0.83, p < 0.0001). The SUV measured by quantitative bone SPECT/CT was increased at the epiphyseal plates of children under the age of 15 years in comparison with the older group, corresponding to higher osteoblastic activity. Moreover, this study suggested a correlation between growth velocity and the SUV. Although this is a small retrospective pilot study, the objective and quantitative values measured by the quantitative bone SPECT/CT has the potential to improve the management of children with growth disorder.

To examine medium- to long-term orthodontic treatment stability and its possible association with certain variables. In a retrospective longitudinal study of 70 postretention patients, the Peer Assessment Rating (PAR) index was measured at the start (T1) and end (T2) of treatment and between 4 and 10 years afterwards (T3). The stability was considered absolute when the T2 and T3 values were identical and relative when the difference was within the ±5 range. Among the 70 patients, 65.8% were female and 34.2% were male. Their mean age was 14.5 years. The mean treatment length was 2.4 years. The mean retention phase was 3.3 years. The mean pre- and posttreatment PAR scores were 29.8 (T1) and 6.3 (T2). The mean T1-T2 difference was 23.6. The mean T2-T3 difference was -0.39. Within the study, 7.1% presented absolute stability and 68.6% presented relative stability. Lower anterior segment alignment and overbite were the most unstable occlusal features and tended to worsen. Fixed retainer (odds ratio [OR] 0.31; 95% confidence interval [CI] 0.10-0.98) as a protective factor and years without retention (OR 1.32; 95% CI 1.03-1.68) as a risk factor are predictor variables of instability in the case of lower anterior segment alignment. The PAR value at the end of treatment (OR 1.29; 95% CI 1.08-1.54) and extractions (OR 4.76; 95% CI 1.05-21.6) before treatment are predictors for midline instability.

To identify factors that might contribute to pregnancies reported after hysteroscopic sterilization worldwide. Retrospective review of commercial data compiled from the MAUDE database, medical literature, and manufacturer reports received during commercial distribution of hysteroscopic sterilization micro-inserts from 2001 through 2010 (Canadian Taskforce classification III descriptive study). From 2001 through 2010, 497 305 hysteroscopic sterilization kits were distributed worldwide, and 748 pregnancies were reported, i.e., 0.15% of the estimated user population based on the number of distributed kits. The data were sufficient to enable analysis of 508 pregnancies for potential contributing factors and showed most to be associated with patient or physician noncompliance (n = 264) or misinterpreted confirmation tests (n = 212). Conceptions deemed to have occurred within 2 weeks of the procedure and therefore too early for detection were identified in 32 cases. Although there are limitations to the dataset and the study design is retrospective, it represents the largest body of cumulative hysteroscopic sterilization data available to date. Of the 748 pregnancies reported, it is apparent that some might have been prevented with greater patient and clinician attention to interim contraceptive use and counseling and with more rigorous evaluation and informed interpretation of the procedure confirmation tests. Although the estimated pregnancy rate based on such a dataset is likely an underestimation, it does suggest that the evaluable field performance of hysteroscopic sterilization micro-inserts is consistent with the labeled age-adjusted effectiveness of 99.74% at 5 years.

Two cases of hematological malignancies were reported in an industrial radiography company over a year, which were reasonably suspected of being consequences of prolonged exposure to ionizing radiation because of the higher incidence than expected in the general population. We analyzed chromosomal aberrations in the peripheral blood lymphocytes from the other workers who had been working under similar circumstances as the patients in the company. Among the subjects tested, 10 workers who belonged to the highest band were followed up periodically for 1.5 years since the first analysis. The aim of this study was to clarify pertinence of translocation analysis to an industrial set-up where chronic exposure was commonly expected. To be a useful tool for a retrospective biodosimetry, the aberrations need to be persistent for a decade or longer. Therefore we calculated the decline rates and half-lives of frequency for both a reciprocal translocation and a dicentric chromosome and compared them. In this study, while the frequency of reciprocal translocations was maintained at the initial level, dicentric chromosomes were decreased to 46.9% (31.0-76.5) of the initial frequency over the follow-up period. Our results support the long-term stability of reciprocal translocation through the cell cycle and validate the usefulness of translocation analysis as a retrospective biodosimetry for cases of occupational exposure. © The Author 2015.

Bronchiolitis is an acute inflammatory injury of the bronchioles, and is the most frequent cause of hospitalization for lower respiratory tract infections in preterm infants. This was a retrospective, observational, case-control study conducted in Italy, based on administrative database analysis. The aim of this study was to evaluate differences in health care costs of preterm infants with and without early hospitalization for bronchiolitis. Preterm infants born in the period between January 1, 2009 and December 31, 2010 and hospitalized for bronchiolitis in the first year of life were selected from the ARNO Observatory database and observed for the first 4 years of life. These preterm infants were compared (paired 1-3) with preterm infants who were not hospitalized for bronchiolitis in the first year of life and with similar characteristics. Only direct health care costs reimbursed by the Italian National Health Service were considered for this study (drugs, hospitalizations, and diagnostic/therapeutic procedures). Of 40,823 newborns in the accrual period, 863 were preterm with no evidence of prophylaxis, and 22 preterm infants were hospitalized for bronchiolitis (cases) and paired with 62 controls. Overall, cases had 74% higher average cost per infant in the first 4 years of life than controls (18,624€ versus 10,189€, respectively). The major cost drivers were hospitalizations, accounting for >90% in both the populations. The increase in total yearly health care cost between cases and controls remained substantial even in the fourth year of life for all cost items. A relevant increase in hospitalizations and drug consumption linked to respiratory tract diseases was noted in infants hospitalized for bronchiolitis during the entire follow-up period. Preterm infants hospitalized for bronchiolitis in the first year of life were associated with increased resource consumption and costs throughout the entire period of observation; even in the fourth year, the difference versus paired controls was relevant.

The purpose of this study was to evaluate the clinical, radiographic, and patient-based outcomes of dental implants placed at an undergraduate student dental clinic. A retrospective study was performed to determine the success and survival rates of dental implants placed at the undergraduate dental clinic at Dalhousie University between January 1999 and January 2012. Only patients with a minimum of 1-year follow-up were included. Clinical and radiographic assessments determined implant success and survival rates. Questionnaires recorded patients' satisfaction with esthetics, comfort, and ease of hygiene. Of the 352 patients (n = 591 implants) who received implants over 13 years, 165 patients completed the clinical and radiographic examinations. By the end of the study period, demographic information and implant characteristics were collected for 111 (n = 217 implants; 47.5% in the maxilla, 52.6% in the mandible) of these patients. Of those assessed clinically, 36.4% were males and 63.6% females, with a mean age of 56.1 ± 14.15 years (range, 17 to 86 years) at the time of implant placement. The mean follow-up period was 5.8 years (range, 1 to 13 years). The overall implant success and survival rates were 88.0% and 97.2%, respectively. No observable bone loss was evident in 88.0% of the surviving implants. There were no implant fractures. Most patients (91.2%) were very satisfied with the implant restoration appearance, 88.0% were very comfortable with the implant, 92.6% were very satisfied with their ability to chew, and 84.8% reported easy hygiene maintenance at the implant sites. Implant success and survival in an undergraduate student clinic were comparable to those reported in the literature. It seems that inexperienced students were able to provide restorations that were very satisfying to the patients.

This retrospective cohort study evaluated the impact of the Stress Check Program, a recently introduced national policy and program aimed at reducing psychological distress among Japanese workers. A baseline survey was conducted from November 2015 to February 2016, the period when Japan began enforcing the Stress Check Program. A one-year follow-up survey was conducted in December 2016. In the follow-up survey, two exposure variables were collected: having taken the annual stress survey, and experiencing an improvement in the psychosocial work environment. Psychological distress was assessed using the Brief Job Stress Questionnaire (BJSQ) at baseline and 1-year follow-up. The two exposure variables were used to define four groups: "Neither", "Stress survey (SS) only", "Psychosocial work environment improvement (WI) only", and "Both". BJSQ results were analyzed using repeated measures general linear modeling (GLM). The study included 2,492 participants: 1,342 in the "Neither" group, 1,009 in the "SS only" group, 76 in the "WI only" group, and 65 in the "Both" group. Overall time-group interaction effects were not significant. The "Both" group showed significantly greater improvements in psychological distress than the "Neither" group (p = 0.02) at the 1-year follow-up, although the effect size was small (d = -0.14). Combination of the annual stress survey and improvement in psychosocial work environment may have been effective in reducing psychological distress in workers, although the effect size was small.

In 2004, Patient Rights Units were established in all public hospitals in Turkey to allow patients to voice their complaints about services. To determine what violations are reflected into the complaint mechanism, the pattern over time, and patients' expectations of the services. Descriptive study. A retrospective study performed using the complaint database of the Istanbul Health Directorate, from 2005 to 2011. The results indicate that people who are older than 40 years, women, and those with less than high school education are the most common patients in these units. A total of 218,186 complaints were filed. Each year, the number of complaints increased compared to the previous year, and nearly half of the applications were made in 2010 and 2011 (48.9%). The three most frequent complaints were "not benefiting from services in general" (35.4%), "not being treated in a respectable manner and in comfortable conditions" (17.8%), and "not being properly informed" (13.5%). Two-thirds of the overall applications were found in favour of the patients (63.3%), and but this rate has decreased over the years. Patients would like to be treated in a manner that respects their human dignity. Educating healthcare workers on communication skills might be a useful initiative. More importantly, health policies and the organisation of services should prioritise patient rights. It is only then would be possible to exercise patient rights in reality.

The purpose of this retrospective analysis is to document and discuss the features, treatment rendered and result of 25 histologically proven cases of ossifying fibromas of jaw bones operated by a single surgeon over a period of 10 years. The records of ossifying fibroma were obtained from the archives of Oral and Maxillofacial Surgery at Maulana Azad Institute of Dental Sciences (MAIDS) from 2001 to 2011. Only those cases were included in the study where definitive surgery was performed based on clinical, radiological & histopathological features. Twenty-five patients were analyzed with a final diagnosis of ossifying fibroma comprising of 14 males (56 %) and 11 females (44 %). The age range was 11-45 years with a mean of 24.12 years. Mandible was involved in 72 % and maxilla in 28 % cases with a predominance of mandibular posterior [19 (76 %)] cases. The study showed similar findings in regard to clinical, radiographic & histological features of ossifying fibroma as compared to other studies. It also showed that the treatment rendered in the form of eneucleation, curettage or resection of the lesion depending on its stage and extent were adequate, as no recurrence has been reported till date. Enucleation is preferred in small and well demarcated lesions. Curettage should be done in relatively large lesions with ill defined borders, not involving basal bone of mandible or cortical perforation. Resection should be reserved for aggressive and extensive cases with involvement of basal bone or perforation of cortices.

This retrospective cohort study aims to investigate the impact of regular pre- and postoperative geriatric input into the management of geriatric patients with hip fracture, with specific interests in morbidity and mortality. Patients with hip fracture (n = 548) older than 60 years were identified within a 2-year period. In the first year, the patients (n = 270) were managed mainly by orthopedics and this group constituted the control group. In the second year, this group of patients (orthogeriatric group, n = 278) had reviews by orthopedic surgeons and geriatricians (physicians specializing in medicine for the elderly), within 48 hours of admission and regularly thereafter. The main outcomes measured included demographics, length of hospital stay, postoperative complications, mortality, and functional outcomes. Data were collected from records of acute and rehabilitation admissions, and outpatient consultations. The admission to operation time for those in the orthogeriatric group was shorter by 17% (p = 0.02). The percentage of patients deceased at 12 months postoperative was 11.5% for the orthogeriatric group and 20.4% for the conventional group (p = 0.02). A higher percentage of patients in the orthogeriatric group remained independent for daily living activities (24.5%) when compared with the conventional group (23.7%; p = 0.02). In addition to existing evidence that postoperative orthogeriatric collaboration improves mortality and functional outcomes in older patients with hip fractures, this study suggests that allowing preoperative geriatric input in this model of care can produce even more superior results.

Collegiate-level musical theater performance students are a specialized group of vocal performers, who rely on frequent and optimal voice use for their academic advancement and ultimate livelihood. The purpose of this study was to gather information to develop a greater understanding of vocal health and practice patterns of incoming collegiate-level musical theater performers. Data obtained from questionnaires completed by freshman musical theater majors were retrospectively analyzed to gather information about baseline vocal habits of the participants. Results of a questionnaire were obtained from incoming freshman musical theater students at the Cincinnati Conservatory of Music over a period of 10 years (2002-2011). One hundred eighty-eight participants (female = 90) (male = 98) with an average age of 18.28 years (standard deviation = 0.726) were included. Results specifying participants' self-reported vocal training and practice habits, vocal health and hygiene practices, and current vocal symptoms or contributing factors to potential voice problems are provided. Data obtained from the participants revealed that the potential for vocal problems exists in this group of performers, as over half of the subjects reported at least one current negative vocal symptom. The findings from this study provide information that may be useful for individuals who are involved in the training of vocal performers. Copyright © 2014 The Voice Foundation.

Rocky Mountain spotted fever (RMSF), a lethal tick-borne illness, is prevalent in the south central United States. Children younger than 10 years old have the greatest risk of fatal outcome from RMSF. The objective of the current study was to review pediatric cases of RMSF seen in the dermatology consult service and to evaluate dermatology's role in the diagnosis and management of this disease. A retrospective review was performed of inpatient dermatology consultations at a tertiary care center in North Carolina from 2001 to 2011. Data collected included patient demographic characteristics, symptoms, pre- and postconsultation diagnoses, diagnostic procedures, length of hospital stay, and outcome. A total of 3,912 consultations were conducted in the dermatology service over 10 years. Six patients with RMSF, ranging in age from 22 months to 10 years (mean 5.1 years), were evaluated during April, May, and June. All preconsultation diagnoses included RMSF in the differential diagnosis. All patients underwent skin biopsies, and a culture was obtained in one case. Fifty percent of patients died within 4 days of hospitalization. Variables associated with mortality from RMSF are delayed diagnosis and initiation of antirickettsial therapy. Physicians should consider RMSF in children presenting with fever and rash during the summer months. Dermatology consultation is useful in evaluating patients with suspicious clinical features of RMSF with skin findings. © 2016 Wiley Periodicals, Inc.

Screening for opportunistic infections prior to starting biological therapy in patients with inflammatory bowel disease is recommended. To assess adherence to screening for opportunistic infections prior to starting biological therapy in Crohn's disease patients and its yield. A multicentre retrospective study was conducted in Crohn's disease patients in whom infliximab or adalimumab was started between 2000 and 2010. Screening included tuberculin skin test, interferon-gamma release assay or chest X-ray for tuberculosis. Extended screening included screening for tuberculosis and viral infections. Patients were followed until three months after ending treatment. Primary endpoints were opportunistic and serious infections. 611 patients were included, 91% on infliximab. 463 (76%) patients were screened for tuberculosis, of whom 113 (24%) underwent extended screening. Screening for tuberculosis and hepatitis B increased to, respectively, 90-97% and 36-49% in the last two years. During a median follow-up of two years, 64/611 (9%, 3.4/100 patient-years) opportunistic infections and 26/611 (4%, 1.6/100 patient-years) serious infections were detected. Comorbidity was significantly associated with serious infections (hazard ratio 3.94). Although screening rates for tuberculosis and hepatitis B increased, screening for hepatitis B was still suboptimal. More caution is required when prescribing biologicals in patients with comorbid conditions. Copyright © 2014 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

Retrospective cohort review. To assess whether immediate postoperative neck pain scores accurately predict 12-month visual analog scale-neck pain (VAS-NP) outcomes following Anterior Cervical Discectomy and Fusion surgery (ACDF). This was a retrospective study of 82 patients undergoing elective ACDF surgery at a major academic medical center. Patient reported outcomes measures VAS-NP scores were recorded on the first postoperative day, then at 6-weeks, 3, 6, and 12-months after surgery. Multivariate correlation and logistic regression methods were utilized to determine whether immediate postoperative VAS-NP score accurately predicted 1-year patient reported VAS-NP Scores. Overall, 46.3% male, 25.6% were smokers, and the mean age and body mass index (BMI) were 53.7 years and 28.28 kg/m 2 , respectively. There were significant correlations between immediate postoperative pain scores and neck pain scores at 6 weeks VAS-NP ( P = .0015), 6 months VAS-NP ( P = .0333), and 12 months VAS-NP ( P = .0247) after surgery. Furthermore, immediate postoperative pain score is an independent predictor of 6 weeks, 6 months, and 1 year VAS-NP scores. Our study suggests that immediate postoperative patient reported neck pain scores accurately predicts and correlates with 12-month VAS-NP scores after an ACDF procedure. Patients with high neck pain scores after surgery are more likely to report persistent neck pain 12 months after index surgery.

Original data reported a potential increased incidence of thyroid cancer surrounding the Three Mile Island (TMI) nuclear facility. A causal link to the accident, however, was indeterminate. Our objective was to determine if data 30 years later will change original conclusions, explore thyroid cancer incidence rates near nuclear power plants, and better understand effects of chronic low level radiation. Retrospective cross-sectional study. Retrospective data for specific Pennsylvania counties were provided by the Pennsylvania Cancer Registry Dataset for thyroid cancer using the Epidemiological Query and Mapping System search engine. Our study examines thyroid cancer incidence from 1985 through 2009 analyzed by year, county, and age. Thirty years after the TMI accident, an increased incidence of thyroid cancer is seen in counties south of TMI and in high-risk age groups. The average incidence rates from 1990 through 2009 were greater than expected in York, Lancaster, Adams, and Chester Counties. Thyroid cancer incidence since the TMI accident was greater than expected in the counties analyzed when compared to local and national population growth. This supports a link to chronic low level radiation exposure and thyroid cancer development. Despite these findings, a direct correlation to the accident remains uncertain as incidence rates may coincide with other factors, and original data were limited. © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

A retrospective study was carried out between 2006-2011. Six hundred and eighteen patients with suspected allergic contact dermatitis underwent the standard patch test series recommended by the Brazilian Contact Dermatitis Research Group. The aim of our study was to evaluate the variation of positive patch-test results from standard series year by year. The most frequently positive allergens were: nickel sulfate, thimerosal and potassium bichromate. Decrease of positive patch-test results over the years was statistically significant for: lanolin (p=0.01), neomycin (p=0.01) and anthraquinone (p=0.04). A follow-up study should be useful in determining which allergens could be excluded from standard series, as they may represent low sensitization risk.

Dysplastic nevi with severe atypia (severely dysplastic nevi [SDN]) are frequently re-excised because of the concern that these lesions may in fact represent early melanoma. Data on long-term follow-up of these patients are limited. We sought to determine the rate of subsequent melanoma development in patients with SDN who underwent re-excision versus those who did not and to determine factors associated with decision to re-excise. A retrospective single institutional study was conducted with 451 adult patients (mean age 41.3 years) with SDN biopsied between November 1994 and November 2004, with clinical follow-up of at least 5 years. In 451 patients with SDN, re-excision was performed on 36.6%. Two melanomas were diagnosed in the re-excision specimens. Subsequent metastatic melanoma developed in 7 patients, all of whom had a history of melanoma. Margin comments influenced decision to re-excise. This was a retrospective study at a single institution. Re-excision of all SDN may not be necessary. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc.

A retrospective study of autopsy cases was conducted at the Department of Forensic Medicine, Tongji Medical College (DFM-TMC), in Hubei, China to describe the characteristics of poisoning deaths from 1999 to 2008. A total of 212 poisoning deaths were investigated by DFM-TMC during the 10-year period. The poisoning deaths ranged from 17 cases in 1999 to 27 cases in 2008. Of the 212 cases, 82 deaths (38.7%) were from pesticides, 36 deaths (17.0%) from carbon monoxide, 34 deaths (16.0%) from drugs, 22 deaths (10.4%) from alcohol, 17 deaths (8.0%) from other chemicals, 15 deaths (7.1%) from poisonous plants and animals, and six deaths (2.8%) from heavy metals. Of the 82 pesticide poisoning deaths, 43 (52.4%) cases were caused by rodenticides, mainly tetramine (N = 39). The majority of poisoning deaths were accidents (63.7%), followed by suicides (25.9%) and homicides (3.8%). The manner of death could not be determined in 14 cases (6.6%). © 2010 American Academy of Forensic Sciences.

Somatization in Post-Concussion Syndrome: A Retrospective Study

Gibaldi, James C

2016-01-01

This is a retrospective study of concussion patient data conducted to analyze the prevalence of somatization in patients presenting with post-concussion symptoms. Patient records from June 2010 to December 2015 were examined for concussion history, psychosocial history, neuropsychological test results, validity scores, and a symptom severity scale. Records meeting inclusion criteria from 33 males and 27 females were located. The sample had an age range of 11–78 years with a mean age of 33.40 (SD +/- 7.5 years). A clinically significant number of patients (55%) were found to be somaticizing their symptoms and a significant majority (78%) of somaticizing patients reported no loss of consciousness, retrograde amnesia, or post-traumatic amnesia but their symptom validity scales were significantly exaggerated. Caution should be exercised by clinicians to ensure that the obtained results of neuropsychological testing are reliable and valid. It is very important for the clinician to take into account the entire patient history, including psychosocial factors (such as pre-existing psychological traits or conditions) and social influences (such as stressors in family dynamics or work/school activities that may be affecting the patient's complaints).

2016-03-01

Retrospective data of 32 patients supplied with implant-supported and Locator-attached overdentures were screened for prosthetic complications and maintenance requirements, which were recorded and statistically analyzed. Mean observation time was 4.78 ± 1.72) years. Loss of retention was the most frequently observed event (n = 22). Damage and exchange of the insert holders (n = 4) and loosening of locator attachments (n = 2) and fracture of the insert holder (n = 2) were uncommon events; no loss of locator attachments was observed. Loss of retention in Locator-attached overdentures is frequent; correlating patient-specific parameters with prosthetic complications is necessary to define recommendations for the use of Locator attachments.

The purpose of this study was to analyze the incidence, clinical presentation, diagnosis, and treatment of false traumatic aneurysms and arteriovenous fistulas as well as the outcomes of the patients. A retrospective, 16-year survey has been conducted regarding the cases of patients who underwent surgery for false traumatic aneurysms (FTA) of arteries and traumatic arteriovenous fistulas (TAVF). Patients with iatrogenic AV fistulas and iatrogenic false aneurysms were excluded from the study. There were 36 patients with TAVF and 47 with FTA. In all, 73 (87.95%) were male, and 10 (12.05%) were female, with an average age of 36.93 years (13-82 years). In 25 (29.76%) cases TAVF and FTA appeared combat-related, and 59 (70.24%) were in noncombatants. The average of all intervals between the injury and surgery was 919. 8 days (1 day to 41 years) for FTA and 396.6 days (1 day to 9 years) for TAVF. Most of the patients in both groups were surgically treated during the first 30 days after injury. One patient died on the fourth postoperative day. There were two early complications. The early patency rate was 83.34%, and limb salvage was 100%. There were no recurrent AV fistulas that required additional operations. Because of their history of severe complications, FTA and TAV fistulas require prompt treatment. The treatment is simpler if there is only a short interval between the injury and the operation. Surgical endovascular repair is mostly indicated.

Effectiveness of Omalizumab in Severe Allergic Asthma: A Retrospective UK Real-World Study

PubMed Central

2013-01-01

Objective. The aim of this study was to evaluate the “real world” effects of the monoclonal antibody omalizumab (OMB) when used to treat severe persistent allergic asthma in UK clinical practice. Methods. A 10-center retrospective observational study was carried out to compare oral corticosteroid (OCS) use and exacerbation frequency in 12 months pre- versus post-OMB initiation in 136 patients aged ≥12 years with severe persistent allergic asthma. All patients received ≥1 dose of OMB. Patients who had received OMB in a clinical trial were excluded. Data were obtained from hospital and if necessary general practitioners’ (GPs’) records on OCS use, lung function, hospital resource use, and routinely used quality of life (QoL) measures at baseline (pre-OMB), 16 weeks, and up to 12 months post-OMB initiation. Results. Mean total quantity of OCS prescribed per year decreased by 34% between the 12 months pre- and post-OMB initiation. During the 12 months post-OMB initiation, 87 patients (64%) stopped/reduced OCS use by 20% or more and 66 (49%) stopped OCS completely. Mean percent predicted forced expiratory volume in one second (FEV1) increased from 66.0% at baseline to 75.2% at week 16 of OMB therapy. The number of asthma exacerbations decreased by 53% during the 12 months post-initiation. Accident and emergency visits reduced by 70% and hospitalizations by 61% in the 12 months post-OMB initiation. Conclusion. This retrospective analysis showed a reduction in exacerbations and improved QoL as per previous studies with OMB. However, the total reduction in annual steroid burden and improved lung function in this severely ill group of patients taking regular or frequent OCS is greater than that seen in previous trials.

Lacosamide is an antiepileptic drug approved for the treatment of focal epilepsy in adult patients. The aim of this observational study was to review our centre's experience with lacosamide and to characterize its effectiveness and tolerability as an adjunctive antiepileptic drug in a retrospective cohort of children with refractory focal epilepsy. We retrospectively reviewed the medical records of 22 patients who received lacosamide from November 2009 to April 2014 at the CHU Ste-Justine, University of Montreal. Treatment responders were defined as children with a ≥50% reduction in seizure frequency compared to baseline, and this was determined three months after the initiation of treatment and at the last follow-up visit. We included 14 boys and eight girls with a mean age of 12.9 years (SD: 5.2; range: 5.2-20.7 years) at the initiation of treatment. The average length of follow-up was 11.9 months. Patients had previously received an average of 7.5 antiepileptic drugs. The mean number of concomitant antiepileptic drugs was 2.3. The mean initial and maintenance doses were 2.9 and 8.4 mg/kg/d, respectively. Thirteen (59%) and ten (45%) patients were responders after three months of treatment and at the last follow-up visit, respectively. One became seizure-free. Adverse effects were reported in 11 patients and none were severe. Responders and non-responders were identical with respect to all studied parameters except gender, with the proportion of responders being greater in girls than in boys (75% vs 29%; p=0.035). Our study adds evidence that lacosamide appears to be a safe and effective adjunctive therapy for children with refractory focal epilepsy.

The present observational, multicenter, retrospective study investigated the efficacy and tolerability of lacosamide in controlling secondary epileptic seizures in patients with brain tumors in Spain. Data from the medical records of patients ≥18 years of age with brain tumors, who had received at least one dose of lacosamide for seizure management between July 2013 and November 2013, were collected. The primary and secondary objectives of the present study were to assess the effectiveness and tolerability of lacosamide. Data from 39 patients (mean age, 54.1 years; 66.7% male) were collected, where the two main reasons for initiation of lacosamide treatment were the lack of efficacy of other antiepileptic drugs (in 76.9% of patients) and the presence of adverse events (12.8%) associated with other antiepileptic drugs. At the initiation of treatment, patients received a mean lacosamide dose of 138.5±68.3 mg/day. At 6 months, lacosamide had significantly reduced the mean number of seizures from 26.4 (standard deviation [SD], 50.4) seizures for the 6 months prior to lacosamide initiation to a mean of 9.4 (SD, 22.8) seizures during the 6 months subsequent to lacosamide initiation; P<0.001. Lacosamide was generally well tolerated; of the 25 patients who had complete safety data available at a 6-month follow-up, 3 patients (12%) reported an adverse event, including dizziness, asthenia, instability and irritability. The present retrospective analysis suggested that lacosamide is an effective and well-tolerated treatment in patients experiencing seizures due to brain tumors. Additional prospective studies with a larger patient population and randomized trial design are warranted. PMID:28599411

The aim of this retrospective study was to determine the long-term effect of exercise on bone mineral density (BMD), bone mineral content (BMC) and body composition (BC) in post-menopausal women who were elite athletes during their youth compared with sedentary controls. It is a retrospective study and carried out in an outpatient clinic. A total of 48 post-menopausal women (54-73 years of age) were enrolled. Ex-elite athletes with long-term (>20 years) histories of significant training and performance were divided into two groups: weight-bearing sports (runners, n=12) and non-weight-bearing sports (swimmers, n=12). The athletes were age matched with sedentary controls (n=24). BMD, BMC and BC were measured using dual-energy X-ray absorptiometry. Healthcare and sport activity histories were evaluated using a questionnaire. No significant differences were found with regard to body weight, height, body mass index and hours of activity between the two groups of athletes. There were no significant differences in activity levels between athletes and controls at the time of this study. BMD and BMC were not significantly different between athletes; they were significantly higher in athletes than in controls (P<0.001). Although the ex-athletes did not significantly differ in BC, left and right lean arm mass and arm BMD were significantly higher in swimmers than in runners (P<0.0001). The high level of physical activity observed in female athletes is associated with improved muscle mass, BMD and BMC, and physical activity during youth seems to have a beneficial effect on bone mass and helps to prevent bone loss due to aging.

A comparison study: image-based vs signal-based retrospective gating on microCT

NASA Astrophysics Data System (ADS)

Liu, Xuan; Salmon, Phil L.; Laperre, Kjell; Sasov, Alexander

2017-09-01

Retrospective gating on animal studies with microCT has gained popularity in recent years. Previously, we use ECG signals for cardiac gating and breathing airflow or video signals of abdominal motion for respiratory gating. This method is adequate and works well for most applications. However, through the years, researchers have noticed some pitfalls in the method. For example, the additional signal acquisition step may increase failure rate in practice. X-Ray image-based gating, on the other hand, does not require any extra step in the scanning. Therefore we investigate imagebased gating techniques. This paper presents a comparison study of the image-based versus signal-based approach to retrospective gating. The two application areas we have studied are respiratory and cardiac imaging for both rats and mice. Image-based respiratory gating on microCT is relatively straightforward and has been done by several other researchers and groups. This method retrieves an intensity curve of a region of interest (ROI) placed in the lung area on all projections. From scans on our systems based on step-and-shoot scanning mode, we confirm that this method is very effective. A detailed comparison between image-based and signal-based gating methods is given. For cardiac gating, breathing motion is not negligible and has to be dealt with. Another difficulty in cardiac gating is the relatively smaller amplitude of cardiac movements comparing to the respirational movements, and the higher heart rate. Higher heart rate requires high speed image acquisition. We have been working on our systems to improve the acquisition speed. A dual gating technique has been developed to achieve adequate cardiac imaging.

Lithuania is one of the countries with the highest incidence of tick-borne encephalitis (TBE) in Europe. The aim of this study was to describe the epidemiological patterns of TBE in Lithuania, and characterize clinical features in adults in the light of the high incidence in recent years. Surveillance data available on the website of the Centre for Communicable Diseases and AIDS of Lithuania were used to describe the epidemiological patterns of TBE. The retrospective study included 712 patients hospitalized in the Centre for Infectious Diseases and the Centre for Neurology of Vilnius University in the years 2005-2014. Tick-borne encephalitis incidence rates have been increasing by 8.5% per year for the 45-year period from 1970 to 2014. The joinpoint model finds two joinpoints at 1991 and 1994, with a significant decrease of 8.4% per year (P < 0.05) prior to the joinpoint at 1991, and a rise of 195.2% afterwards. TBE presented with meningoencephalitis in 556 cases (81.3%). A total of 129 patients (18%) had a severe case of the disease. The most common neurological signs were ataxia (579, 81.3%), meningeal signs (474, 66.5%) and tremor (338, 47.5%). Limb paresis was observed in 6.3% of patients. Five patients (0.7%) died, and 544 patients (76.7%) were discharged with sequelae. Intensified efforts in promoting TBE vaccination will be needed in the light of the high incidence and expanded spatial distribution. Significant prognostic factors for severe cases of the disease were age above 61 and delayed immune response of specific immunoglobulin G. © 2017 The Authors.

The present study aimed to evaluate the risk of retinal vein occlusion (RVO) in Korean patients with end-stage renal disease (ESRD). In this retrospective, nationwide, propensity score-matched cohort study, subjects were randomly enrolled from the 12-year longitudinal Korean National Health Insurance Service-National Sample Cohort 2002-2013 database comprising 1 million subjects. The ESRD group comprised 988 patients newly diagnosed with ESRD from 2003 onward by washing out data from 2002. The comparison group comprised 4940 (5 for each patient with ESRD) randomly selected propensity score-matched individuals not diagnosed with ESRD. Each sampled patient was tracked until 2013 for RVO development. Multiple conditional Cox regression analysis was performed to compare the risk of RVO between the two groups. The mean follow-up period was 7.37 years. The incidence of RVO was 3.95% in the ESRD group and 2.17% in the comparison group (P = 0.001). ESRD was associated with greater risk of RVO development after adjustment for possible confounders (adjusted hazard ratio [HR], 2.122; 95% confidence interval [CI], 1.396-3.226; P = 0.0004). The 50- to 60-year (adjusted HR, 2.635; 95% CI, 1.100-6.313; P = 0.0297) and 60- to 70-year (adjusted HR, 2.544; 95% CI, 1.059-6.110; P = 0.0368) age groups exhibited higher risk of RVO compared with the <40-year age group. Hyperlipidemia (adjusted HR, 1.670; 95% CI, 1.176-2.371; P = 0.0042) and hypertension (adjusted HR, 1.896; 95% CI, 1.165-3.086; P = 0.01) were also associated with RVO. An association between ESRD and subsequent RVO development was found after adjustment for possible confounding factors.

While studies demonstrated favorable outcomes of nocturnal home hemodialysis (NHHD), direct comparison on employment rate, clinical and laboratory outcomes between the NHHD and continuous ambulatory peritoneal dialysis (CAPD) had not been previously performed. A 1-year retrospective observation study was performed in 20 incidents alternate night NHHD and 81 incident CAPD patients of Chinese ethnicity, who were sex, diabetic status, and Charlson comorbidity index matched, but not age due to our center's age limit for NHHD enrollment. The primary outcome was the difference in employment rate at 1 year. Secondary outcomes included differences in clinical parameters (weight, blood pressure, number of antihypertensive medication, dosage of phosphate binders, and erythropoietin stimulating agent) and laboratory parameters (residual renal function, mineral metabolic markers, hemoglobin). NHHD subjects were 5 years younger than CAPD patients, and they had higher employment rate (80% vs. 33.3%, P < 0.01) at 1 year, with age-adjusted odds ratio for employment was 6.10 (95% confidence interval 1.77-20.99, P = 0.04). They consumed less aluminum-based phosphate binder (0 vs. 1800 mg, P < 0.01), but showed no significant disparities in other clinical parameters. Residual renal function in both groups declined comparably, nonetheless NHHD group had lower serum phosphate (1.37 vs. 1.71 mmol/L, P = 0.01) and calcium phosphate product (3.13 vs. 4.12 mmol 2 /L 2 , P < 0.01), with similar hemoglobin levels. NHHD appeared to offer higher employment rate, lower dosage of aluminum-based phosphate binder and mineral metabolic markers at 1 year compared with CAPD in Hong Kong. © 2017 International Society for Hemodialysis.

Little is known about the incidence of nephrolithiasis in the United States Navy. Navy pilots must be kidney stone-free and are often referred for treatment of small asymptomatic stones. The primary objectives of this study were to determine the incidence of nephrolithiasis and computerized tomography, proportion undergoing treatment and incidence of stone related mishaps in Navy pilots compared with other Navy personnel. We retrospectively studied the records of all Navy service members from 2002 to 2011 for nephrolithiasis based on ICD-9 stone codes to determine the mentioned rates. We also reviewed NSC (Naval Safety Center) data for a history of accidents associated with nephrolithiasis. Rates of disease were calculated using person-years of followup and inferential statistics were done using univariable and multivariable analyses. We evaluated 667,840 Navy personnel with a total of 3,238,331 person-years of followup. The annual incidence of nephrolithiasis was 240/100,000 person-years with a 5-year recurrence rate of 35.3%. On multivariable analysis pilots had nephrolithiasis incidence and treatment rates similar to those of the overall Navy population. Women had a higher incidence of nephrolithiasis compared with men (OR 1.17, p <0.0001). The rate of computerized tomography was lower in pilots than in the rest of the Navy (39 vs 66/10,000 person-years, p <0.0001). No recorded accidents were associated with kidney stones. Navy pilots had a similar incidence of nephrolithiasis and were no more likely to undergo a surgical procedure. Given that no accidents were associated with nephrolithiasis, this study suggests reconsidering current military policies necessitating pilots to be completely stone-free.

Many patients with epilepsy are treated with antiepileptic drug (AED) polytherapy. Several factors influence the choice of early add-on therapy, and deciding on the most appropriate drug can be difficult. This study aimed to assess the efficacy and tolerability of lacosamide as early add-on therapy in patients with partial-onset seizures. REALLY (REtrospective study of lAcosamide as earLy add-on aLong one Year) was a multicenter, retrospective, 1-year, real-life study. Patients included were aged older than 16 years, had partial-onset seizures, and were treated with lacosamide as add-on therapy after one or two prior AEDs. Data were collected retrospectively from clinical records. The primary study objective was to assess the efficacy of lacosamide over 12 months (seizure-free and responder rates), and the secondary objective was to assess the tolerability of lacosamide at 3, 6, and 12 months [adverse events (AEs) and discontinuation]. One hundred and ninety-nine patients were enrolled in the study; 89 patients (44.7 %) had tried one AED and 110 patients (55.3 %) had tried two AEDs before lacosamide. At 12 months, the proportion of patients who were seizure free was 44.9 %, and 76 % of patients were responders. The seizure-free rate at 12 months for patients who had previously received one or two AEDs was 58 and 34.3 %, and the responder rate at 12 months was 83.0 and 70.4 %, respectively. The AE rate was 21.5 % at 3 months, 27.1 % at 6 months, and 31.2 % at 12 months, with 7.0 % of patients discontinuing treatment because of an AE. The most common AE reported was dizziness (11.6 %). Cryptogenic epilepsy, a higher number of prior AEDs, and the use of a sodium channel blocker at onset were associated with a worse outcome. The number of concomitant AEDs decreased over 1 year (Z = 5.89; p < 0.001). Twenty-two patients were converted to lacosamide monotherapy with at least one evaluation ≥6 months from the beginning of monotherapy conversion. Lacosamide was effective and well tolerated as early add-on treatment in patients who had received one or two previous AEDs.

The aim of this 10-year retrospective study was to evaluate the impact of teaching nursing process to students at different levels of baccalaureate education, using the North American Nursing Diagnosis Association International (NANDA-I) Taxonomy. Nursing care plans written between 1996 and 2006 by 3,784 students who had completed a baccalaureate course in nursing process at a university in northern Italy were evaluated. At least three of the four steps of the nursing process were included in the evaluation: assessing, planning, intervening, and evaluating. An average of 6.3 (range 0-31; +/-3.9; median 6) problems were identified in each care plan. Of these, 5.1 (range 0-29; +/-3.06; median 5) were related to nursing diagnoses concerning either an actual problem or the risk of developing a problem; the remaining 1.2 (range 0-20; +/-1.9; median 0) diagnoses were concerned either with collaborative problems or with potential complications. The students demonstrated significant improvement in accurately identifying 75 diagnostic titles from the NANDA-I Taxonomy as they progressed through their first, second, and third years of baccalaureate study. These findings suggest that the ability to use the NANDA-I Taxonomy accurately is acquired over time. Thus, the theory and practice of using nursing process should be introduced in a formal course during the first year of baccalaureate nursing education and should be reinforced throughout the remaining courses. Students can then progressively improve their knowledge, critical thinking abilities, and use of the NANDA-I Taxonomy during their second and third years of study. Teaching strategies to reinforce students' learning are recommended.

To assess the effectiveness of bracing in adult with scoliosis. Retrospective cohort study. Outpatients followed in 2 tertiary care hospitals. Adults (N=38) with nonoperated progressive idiopathic or degenerative scoliosis treated by custom-molded lumbar-sacral orthoses, with a minimum follow-up time of 10 years before bracing and 5 years after bracing. Progression was defined as a variation in Cobb angle ≥10° between the first and the last radiograph before bracing. The brace was prescribed to be worn for a minimum of 6h/d. Not applicable. Rate of progression of the Cobb angle before and after bracing measured on upright 3-ft full-spine radiographs. At the moment of bracing, the mean age was 61.3±8.2 years, and the mean Cobb angle was 49.6°±17.7°. The mean follow-up time was 22.0±11.1 years before bracing and 8.7±3.3 years after bracing. For both types of scoliosis, the rate of progression decreased from 1.28°±.79°/y before to .21°±.43°/y after bracing (P<.0001). For degenerative and idiopathic scoliosis, it dropped from 1.47°±.83°/y before to .24°±.43°/y after bracing (P<.0001) and .70°±.06°/y before to .24°±.43°/y after bracing (P=.03), respectively. For the first time, to our knowledge, this study suggests that underarm bracing may be effective in slowing down the rate of progression in adult scoliosis. Further prospective studies are needed to confirm these results. Copyright © 2016 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

Background Chlamydia (Chlamydia trachomatis) continues to be a public health challenge in Australia, with some contention as to the best screening approach. In the present study we examined chlamydia testing, positivity and sexual behaviour among women with the aim of informing targeted testing among women aged ≥30 years. A longitudinal analysis was conducted on retrospective surveillance data collected among women attending general practice, family planning and sexual health clinics participating in sentinel surveillance in Melbourne, Australia. Women were aged ≥16 years and underwent urogenital testing for C. trachomatis (chlamydia) at participating clinics between 2007 and 2014. Chlamydia incidence was calculated as positive chlamydia tests over person-years (PY) among women and reported by 5-year age groups. A Cox regression model examined correlates of a positive chlamydia test among women aged ≥30 years. In all, 36770 women contributed 46432 PY and 52395 chlamydia tests, of which 2895 were positive. The overall chlamydia incidence rate was 6.2 per 100 PY (95% confidence interval (CI) 6.0-6.5). Chlamydia incidence declined with age, plateauing to <5 per 100 PY among women aged ≥30 years. Among women aged ≥30 years, being born in North-East Asia (adjusted hazard ratio (aHR) 2.9; 95% CI 1.9-4.5) and reporting multiple partners (aHR 2.5; 95% CI 1.8-3.5) in the past 12 months were associated with a positive chlamydia test. Chlamydia control remains challenging in Australia and optimising testing in primary care is a key priority. The results of the present study suggest that, at least among women aged ≥30 years, chlamydia testing should be risk-based and informed by appropriate sexual history taking.

There is inadequate evidence for the effectiveness and cost-effectiveness of health promotion interventions. The Salut Programme aims to reach all parents and children in the Västerbotten County of Sweden with a combination of health promotion interventions initiated during pregnancy and continued over the childhood period. This study protocol describes an effectiveness study and an economic evaluation study, where the ongoing Salut Programme is compared to care-as-usual over the periods of pregnancy, delivery and the child's first 2 years of life. A register-based retrospective observational study design will be used with existing data sources with respect to exposures and outcomes. Outcomes of interest are clustered at 3 points: around the child's birth, 1 month after the child's birth and 2 years after the child's birth. We will simulate an experiment by retrospectively identifying and comparing children and their parents in the geographical areas where the Salut Programme was implemented since 2006 and onwards, and the areas where the Programme was not implemented before 2009. Outcomes will be analysed and compared for the premeasure period, and the postmeasure period for both groups. Our analysis combines difference-in-difference estimation with matching. A complementary analysis will be carried out on the longitudinal subsample of mothers who gave birth at least once during each of the time periods. The economic evaluation aims to capture the wider societal costs and benefits of the Salut Programme for the first 2 years of the children's lives. Incremental costs will be compared with incremental health gains and the results will be presented as a cost-consequence analysis. The Regional Ethical Review Board in Umeå has given clearance for the Salut Programme research (2010-63-31M). No individual's identity will be revealed when presenting results. This study will provide information that can guide decision-makers to allocate resources optimally. Published by the BMJ Publishing Group Limited.

To define a general methodology for maximising the success of follow-up processes for retrospective cohort studies in New Zealand, and to illustrate an approach to developing country-specific follow-up methodologies. We recently conducted a cohort study of mortality and cancer incidence in New Zealand professional fire fighters. A number of methods were used to trace vital status, including matching with records of the New Zealand Health Information Service (NZHIS), pension records of Work and Income New Zealand (WINZ), and electronic electoral rolls. Non-electronic methods included use of paper electoral rolls and the records of the Registrar of Births Deaths and Marriages. 95% of the theoretical person-years of follow-up of the cohort were traced using these methods. In terms of numbers of cohort members traced to end of follow-up, the most useful tracing methods were fire fighter employment records, the NZHIS, WINZ, and the electronic electoral rolls. The follow-up process used for the cohort study was highly successful. On the basis of this experience, we propose a generic, but flexible, model for follow-up of retrospective cohort studies in New Zealand. Similar models could be constructed for other countries. Successful follow-up of cohort studies is possible in New Zealand using established methods. This should encourage the use of cohort studies for the investigation of epidemiological issues. Similar models for follow-up processes could be constructed for other countries.

Objective. The aim of this study was to evaluate the effect of maternal age on prenatal and obstetric outcome in multiparaous women. Materials and Methods. A retrospective case control study was conducted, including women aged 40 years and over (study group, n = 97) who delivered at 20 week's gestation or beyond and women aged 20–29 years (control group, n = 97). Results. The mean age of women in the study group was 41.2 ± 1.7 years versus 25.4 ± 2.3 years in the control group. Advanced maternal age was associated with a significantly higher rate of hypertension, diabetes mellitus, fetal complication, and 5-minute Apgar scores <7 (P < 0.05). Caeserean section rate, incidence of placental abruption, preterm delivery, and neonatal intensive care unit admission were more common in the older group, but the differences were not statistically significant. Conclusions. Advanced maternal age is related to maternal and neonatal complications. PMID:25954770

Ocular trauma is a major cause of acquired monocular blindness in children. Firework injuries account for 20% of ocular trauma. The purpose of our study was to document the profile of ocular firework injuries in children during the festive season of Diwali and to determine the prevalence of unilateral blindness in them. A retrospective chart analysis of ocular firework injury in children during the festival of Diwali from 2009 to 2013, conducted in a tertiary care eye center in Tamil Nadu, Southern India. Children below 18 years of age with ocular firework injuries who presented to the emergency department for 3 consecutive days - the day of Diwali, 1 day before, and 1 day after Diwali - were included in this study. Eighty-four children presented with firework-related ocular injuries during the study period. Male to female ratio was 4:1 with mean age 9.48 ± 4 years. Forty-four percentage required hospitalization. The prevalence of unilateral blindness in children due to fireworks was found to be 8% (95% confidence interval - 2-13%). Vision 2020 gives high priority to avoidable blindness, especially in children. In our study, for every 12 children who presented with firecracker injury, one resulted in unilateral blindness. This is an avoidable cause of blindness. Awareness needs to be created, and changes in policy regarding sales and handling of firecrackers including mandatory use of protective eyewear should be considered.

The long-term clinical value of the optimization of atrioventricular (AVD) and interventricular (VVD) delays in cardiac resynchronization therapy (CRT) remains controversial. We studied retrospectively the association between the frequency of AVD and VVD optimization and 1-year clinical outcomes in the 199 CRT patients who completed the Clinical Evaluation on Advanced Resynchronization study. From the 199 patients assigned to CRT-pacemaker (CRT-P) (New York Heart Association, NYHA, class III/IV, left ventricular ejection fraction <35%), two groups were retrospectively composed a posteriori on the basis of the frequency of their AVD and VVD optimization: Group 1 (n = 66) was composed of patients 'systematically' optimized at implant, at 3 and 6 months; Group 2 (n = 133) was composed of all other patients optimized 'non-systematically' (less than three times) during the 1 year study. The primary endpoint was a composite of all-cause mortality, heart failure-related hospitalization, NYHA functional class, and Quality of Life score, at 1 year. Systematic CRT optimization was associated with a higher percentage of improved patients based on the composite endpoint (85% in Group 1 vs. 61% in Group 2, P < 0.001), with fewer deaths (3% in Group 1 vs. 14% in Group 2, P = 0.014) and fewer hospitalizations (8% in Group 1 vs. 23% in Group 2, P = 0.007), at 1 year. These results further suggest that AVD and VVD frequent optimization (at implant, at 3 and 6 months) is associated with improved long-term clinical response in CRT-P patients.

Endometriosis has been associated with a higher risk of cutaneous melanoma, but the mechanisms underlying this association are unknown.Some constitutional factors known to influence melanoma risk have been associated with endometriosis in some retrospective studies. However, prospective data are scarce, and more research is needed to confirm this potentially novel endometriosis risk profile. To investigate the relationships between pigmentary traits, family history of melanoma and endometriosis risk, we analysed data from the Nurses’ Health Study II, a cohort of 116 430 female US nurses aged 25–42 years at inclusion in 1989. Data were collected every 2 years with 20 years of follow-up for these analyses. We used Cox proportional hazards regression models to compute relative risks(RRs) and 95% confidence intervals (CIs). During 1 212 499 woman-years of follow-up, 4763 cases of laparoscopically-confirmed endometriosis were reported among premenopausal Caucasian women. Endometriosis risk was increased with presence of naevi on the lower legs (RR=1.08, 95% CI=1.021.14) and higher level of skin’s burning reaction to sun exposure in childhood/adolescence (‘burn with blisters’: RR=1.20,95% CI=1.061.36) compared with ‘practically none’;P(trend)=0.0006) and family history of melanoma (RR=1.13, 95%CI=1.011.26). This assessment reports modest associations between several pigmentary traits, family history of melanoma and endometriosis risk,corroborating the results from previous retrospective studies. Our findings call for further research to better understand the mechanisms under lying these associations.

Objective To describe trends in new drugs launched in the UK from 1982 to 2011 and test the hypothesis that the rate of new drug introductions has declined over the study period. There is wide concern that pharmaceutical innovation is declining. Reported trends suggest that fewer new drugs have been launched over recent decades, despite increasing investment into research and development. Design Retrospective observational study. Setting and data source Database of new preparations added annually to the British National Formulary (BNF). Main outcome measures The number of new drugs entered each year, including new chemical entities(NCEs) and new biological drugs, based on first appearance in the BNF. Results There was no significant linear trend in the number of new drugs introduced into the UK from 1982 to 2011. Following a dip in the mid-1980s (11–12 NCEs/new biologics introduced annually from 1985 to 1987), there was a variable increase in the numbers of new drugs introduced annually to a peak of 34 in 1997. This peak was followed by a decline to approximately 20 new drugs/year between 2003 and 2006, and another peak in 2010. Extending the timeline further back with existing published data shows an overall slight increase in new drug introductions of 0.16/year over the entire 1971 to 2011 period. Conclusions The purported ‘innovation dip’ is an artefact of the time periods previously studied. Reports of declining innovation need to be considered in the context of their timescale and perspective. PMID:23427198

Cryptococcal meningitis (CM) is a common central nervous system infection in HIV-infected patients. This study aimed to determine treatment outcomes among HIV-infected patients who had cryptococcal meningitis and to determine predictors of death. We conducted a retrospective cohort study among HIV-infected patients receiving care at Chiang Mai University Hospital from January 1, 2005 to December 31, 2010. We studied 79 patients; 45 (57.0%) were male and the mean age was 35.1 +/- 7.2 years. Eleven patients (13.9%) had previous opportunistic infection. The most common presenting symptoms were headache (63 patients, 79.8%), fever (49 patients, 62.0%), and altered consciousness (21 patients, 26.6%). The median CD4+ cell count was 20 cells/mm3 [Interquartile range (IQR) 10, 53]. The in-hospital, 90-day, and 1-year mortality rates were 24.1%, 32.4%, and 52.2%, respectively. The CM attributable in-hospital, 90-day and 1-year mortality rates were 13.9%, 20.3%, and 23.2%, respectively. Predictors associated with a 1-year mortality were a high cerebrospinal (CSF) cryptococcal antigen titer (> 1:10,000) [Odds Ratio (OR) =7.08, 95% confidence interval (CI): 1.62-31.00, p = 0.009], and altered consciousness at presentation (OR = 5.27; 95% CI: 1.16-24.05; p = 0.032). Cryptococcal meningitis is an important cause of death in HIV-infected patients. HIV-infected patients with a low CD4+ cell count, a headache, fever and altered consciousness should be investigated for CM and those with a high CSF cryptococcal antigen titer are at high risk for mortality.

Objective The aim of this study is to describe the epidemiological and clinical aspects of patients who applied to the Bursa Nilufer Tuberculosis Dispensary by investigating the trends in epidemics over three decades. Method In this retrospective observational study, the records of all tuberculosis cases (1630 patients) treated in the last 30 years (1985–2014) at the Bursa Nilufer Tuberculosis Dispensary were examined and statistically analyzed. Results Males comprised 65.2% of the patients. The ages of the patients ranged from 1 to 87 years, and the mean age was 37.4 (95% CI: 36.6–38.2). Among the cases, 86.7% were new infections and 74.1% were pulmonary tuberculosis. In the last decade, the education level, the percentage of patients who had received a BCG vaccination, the proportion of women and active employees among them increased (p<0.05), while it decreased among men (p<0.05). Clinical symptoms accompanying TB such as weakness, anorexia, weight loss, and cough, decreased to a statistically significant degree (p<0.05). In the last decade, the mortality rate was 3.6% and increased compared with previous decades (p<0.05). Mortality was higher among patients who were elderly, male, did not have a BCG scar or had a chronic disease (p<0.05). Conclusion This study adds information about the change of TB epidemics in Turkey in the last 30 years. Further studies are needed to determine the risk factors associated with tuberculosis mortality and to evaluate the effectiveness control programs of this disease. PMID:27872739

Plasma metanephrines (PMN) are highly sensitive for diagnosis of pheochromocytoma, but the natural history of PMN before pheochromocytoma diagnosis has not been previously described. The aim of the study was to compare the progression of PMN before pheochromocytoma diagnosis to matched healthy and essential hypertension disease controls. A retrospective case-control Department of Defense Serum Repository (DoDSR) study. We performed a DoDSR study that compared three longitudinal pre-diagnostic PMN for 30 biopsy-proven pheochromocytoma cases to three longitudinal PMN for age, sex, race, and age of serum sample matched healthy and essential hypertension disease controls. Predominant metanephrine (MN) or normetanephrine (NMN) production was identified for each case and converted to a percentage of the upper limit of normal to allow analysis of all cases together. PMN were measured by Quest Diagnostics. The predominant plasma metanephrine (PPM) was >100 and 300% of the upper limit of normal a median of 6.6 and 4.1 years before diagnosis respectively. A greater percentage of pheochromocytoma patients had a PPM >100 and >300% of the upper limit of normal compared with combined healthy and essential hypertension disease controls <2, 2-8, and >8 years prior to diagnosis. For patients with a baseline PPM 90-300% of the upper limit of normal, a 25% rate of rise per year was 100% specific for pheochromocytoma. PPMs elevate years before diagnosis which suggests that delayed diagnoses are common. For mild PMN elevations, follow-up longitudinal PMN trends may provide a highly specific and economical diagnostic tool. © 2016 European Society of Endocrinology.

Retrospective review. The aim of our study was to quantify the frequency of complications associated with recombinant human bone morphogenetic protein 2 (rhBMP-2) use in anterior lumbar interbody fusion (ALIF). The orthopedic subset of the Medicare database (PearlDiver) was queried for this retrospective cohort study using International Statistical Classification of Diseases 9 (ICD-9) and Current Procedure Terminology (CPT) codes for ALIF procedures with and without rhBMP-2 between 2005 and 2010. Frequencies of complications and reoperations were then identified within 1 year from the index procedure. Complications included reoperations, pulmonary embolus, deep vein thrombosis, myocardial infarction, nerve-related complications, incision and drainage procedures, wound, sepsis, pneumonia, urinary tract infections, respiratory, heterotopic ossification, retrograde ejaculation, radiculopathy, and other medical complications. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the statistical significance. We identified a total of 41 865 patients who had an ALIF procedure. A total of 14 384 patients received rhBMP-2 while 27 481 did not. Overall, 6016 (41.8%) complications within 1 year from surgery were noted within the group who received rhBMP-2 and 12 950 (47.1%) complications within 1 year from surgery were recorded in those who did not receive rhBMP-2 (OR = 0.81, CI = 0.77-0.84). Overall, exposure to rhBMP-2 was associated with significantly decreased odds of complications with exception to reoperation rates (0.9% rhBMP-2 vs 1.0% no rhBMP-2; OR = 0.88, CI = 0.71-1.09) and radiculopathy (4.4% rhBMP-2 vs 4.3% no rhBMP-2; OR = 1.02, CI = 0.93-1.13). The use of rhBMP-2 in patients undergoing ALIF procedure was associated with a significantly decreased rate of complications. Further studies are needed to elucidate a true incidence of complication.

[Purpose] The aim of this retrospective study was to determine the associations between clinical, physical, and neurophysiological outcomes and self-reported symptoms and functions of patients after surgical carpal tunnel release. [Subjects and Methods] Among 261 patients who had undergone open surgical carpal tunnel release within the last three years, 83 (mean age 50.27 ± 11.13 years) participated in this study. Their socio-demographics and comorbidities were recorded. The intensity of pain, paresthesia, and fatigue symptoms in the hand were assessed by means of a Visual Analogue Scale, the Semmes-Weinstein Monofilaments test of light touch pressure sensation, and Jamar dynamometry for measurement of grip and pinch strengths. The Boston Carpal Tunnel Questionnaire evaluated the severity of symptoms and hand functional status, and the variables were analyzed by multivariate linear regression. [Results] The severity of the symptoms and functional status of release surgery patients was associated with diabetes mellitus, migraine, night pain, paresthesia and fatigue symptoms, impaired light touch pressure, and lack of medical treatment. [Conclusion] Appropriate post-surgery treatment programs for these factors should be taken into consideration to help patients obtain optimal functionality and health in their daily lives.

Objective Although several studies have been conducted worldwide on factors that might improve residents' knowledge, the relationship between the hospital volume and the internal medicine residents' knowledge has not been fully understood. We conducted a cross-sectional study to compare the relationships of the hospital volume and hospital resources with the residents' knowledge assessed by the In-training Examination. Methods We conducted a retrospective survey and a clinical knowledge evaluation of postgraduate year 1 and 2 (PGY-1 and -2) resident physicians in Japan by using the General Medicine In-training Examination (GM-ITE) in 2014. We compared the ITE score and the hospital volume. Results A total of 2,015 participants (70.6% men; age, 27.3±2.9 years old) from 208 hospitals were retrospectively analyzed. Generalized estimating equations were used, and the results revealed that an increasing number of hospitalizations, decreasing staff number, decreasing age and PGY-2 were significantly associated with higher GM-ITE scores. Conclusion The hospital volume, such as the number of hospitalizations, is thus considered to have a positive impact on the GM-ITE scores.

The purposes of this retrospective clinical review were to: (1) describe the demographics of implant patients, types of implant treatment and implant-supported prostheses in an Advanced Education in Prosthodontic Program, (2) evaluate the survival rate of dental implants placed by prosthodontic residents from 2006 to 2008, and (3) analyze the relationship between resident year of training and implant survival rate. All patients who received dental implants placed by prosthodontic residents from January 2006 to October of 2008 in the Advanced Prosthodontic Program at the University of Illinois at Chicago College of Dentistry were selected for this study. Age, gender, implant diameter, length, implant locations, surgical and restorative detail, and year of prosthodontic residency training were collected and analyzed. Life-table and Kaplan-Meier survival analyses were performed based on implants overall, locations, year of training, and use of a computer-generated surgical guide. A Logrank statistic was performed between implant survival and year of prosthodontic residency training, location, and use of computer-generated surgical guide (α= 0.05). Three hundred and six implants were placed, and of these, seven failed. Life-table and Kaplan-Meier analyses computed a cumulative survival rate (CSR) of 97% for overall implants and implants placed with a computer-generated surgical guide. No statistical difference was found in implant survival rates as a function of year of training (P= 0.85). Dental implants placed by prosthodontic residents had a CSR comparable to previously published studies by other specialties. The year of prosthodontic residency training and implant failure rate did not have any significant relationship. © 2012 by the American College of Prosthodontists.

Background Recent studies have suggested an effect of metformin on mortality for patients with both diabetes and colorectal cancer (crc). However, the literature is contradictory, with both positive and negative effects being identified. We set out to determine the effect of metformin with respect to prognosis in crc patients. Methods After a retrospective chart review of crc patients treated at the Cancer Centre of Southeastern Ontario, Kaplan–Meier analyses and Cox proportional hazards regression models were used to compare overall survival (os) in patients with and without diabetes. Results We identified 1304 crc patients treated at the centre. No significant differences between the diabetic and nondiabetic groups were observed with respect to tumour pathology, extent of metastatic disease, time or toxicity of chemotherapy, and the os rate (1-year os: 85.6% vs. 86.4%, p = 0.695; 2-year os: 73.6% vs. 77.0%, p = 0.265). In subgroup analysis, diabetic patients taking metformin survived significantly longer than their counterparts taking other diabetes treatments (os for the metformin group: 91% at 1 year; 80.5% at 2 years; os for the group taking other treatments, including diet control: 80.6% at 1 year, 67.4% at 2 years). Multivariate analysis suggests that patients with diabetes taking treatments other than metformin experience worse survival (p = 0.025). Conclusions Our results suggest that crc patients with diabetes, excluding those taking metformin, might have a worse crc prognosis. Taking metformin appears to have a positive association with prognosis. The protective nature of metformin needs further evaluation in prospective analyses. PMID:27122979

This study was conducted to evaluate recent clinical and anthropologic features of neonates with reactive serology for syphilis and their mothers from three institutions in Korea over an 11-year-period. The medical records of 20 neonates with reactive serology for syphilis and their mothers at three centers (Kyung Hee University Hospital, Kyung Hee University Hospital at Gangdong, and Korea Electric Power Corporation Hospital) seen between January 2000 and December 2010 were reviewed retrospectively. Among 20 mothers, 16 (80%) were native Korean and four (20%) were foreign-born immigrants. Two mothers (10%) were unmarried. The annual distribution of cases was three (15%) in 2000, one each (5%) in 2005 and 2006, respectively, two each (10%) in 2007 and 2008, respectively, six (30%) in 2009, and five (25%) in 2010. Just over half (55%) occurred across 2009 and 2010. All neonates, by definition, were diagnosed with presumptive congenital syphilis (CS). Among the neonates, four had positive cerebrospinal fluid venereal disease research laboratory test, and three exhibited symptoms and signs. In three centers in Seoul, Korea, the observed number of CS cases was higher in 2009 and 2010 than in previous years. This finding is consistent with a trend toward increasing prevalence of international marriage and suggests that more meticulous screening of CS is needed. © 2015 Japan Pediatric Society.

Total elbow arthroplasty (TEA) is one option in distal humerus fracture in elderly osteoporotic patients. The study hypothesis was that, in patients aged 70years or more, TEA provides functional results and ranges of motion compatible with everyday activity, with a complications rate equal to or lower than with internal fixation, and no loss of autonomy or cognitive impairment. In this retrospective study, 21 patients receiving TEA for distal humerus fracture were included. Mean follow-up was 3.2years, with functional (Quick DASH and MEPS), cognitive (MMSE), autonomy-related (ADL) and radiological assessment (Morrey). Mean MEPS was 84 and QuickDASH 32.4. Mean extension deficit was 22°, and mean flexion 125°. There was no loss of autonomy or cognitive impairment. The complications rate was 9.5%. There were no revision surgeries. TEA proved reliable in comminuted distal humerus fracture in elderly patients. Functional results were comparable to those in the literature, and the complications rate was lower. Long-term implant survival needs confirmation to validate this option as a treatment of choice in these indications in geriatric traumatology. Retrospective non-comparative, single-center. 4.

To evaluate the influence of the weight gain rate at 4-6 months on nutritional status and body composition in children between 4 and 7 years of age. Retrospective cohort study, sample of 257 children. Data collection was performed in two stages, with the first relating to retrospective data of weight gain from birth to the first 4-6 months of life in the patient records. Measurements of weight, height, waist circumference, and body composition in children between ages 4 and 7 years were obtained. Nutritional status was assessed by the BMI/age. Control variables, such as pregnancy, breastfeeding, lifestyle, and sociodemographics, were studied. Descriptive analysis and multiple linear regression were performed. In the nutritional status assessment, the prevalence of overweight observed was 24.9%. After adjusting for control variables, it was found that the increase of the WGR at 4-6 months of age explained the occurrence of higher BMI/age, percentage of total body fat, body fat percentage in the android region, and waist circumference in children between 4 and 7 years of age. The increase of the WGR in the first months of life can lead to the occurrence of higher values of parameters of nutritional status and body composition in later life.

Objectives We sought to elucidate the long-term association of tobacco use and respiratory health in designated pollution victims with and without obstructive pulmonary defects. Design A retrospective cross-sectional study. Setting The register of pollution victims in Kurashiki, Japan. Participants 730 individuals over 65 years of age previously diagnosed with pollution-related respiratory disease. Patients were classified into four groups according to their smoking status and whether they had obstructive pulmonary disease. We then compared the prevalence of respiratory symptoms and lung function over time between groups. Primary outcome measures Spirometry was performed and a respiratory health questionnaire completed in the same season each year for up to 30 years. Results Rates of smoking and respiratory disease were high in our sample. Although respiratory function in non-smoking patients did not completely recover, the annual rate of change in lung function was within the normal range (p<0.01). However, smokers had worse lung function and were more likely to report more severe pulmonary symptoms (p<0.01). Conclusions Patients’ respiratory function did not fully recover despite improved air quality. Our results suggest that, in the context of exposure to air pollution, tobacco use causes additional loss of lung function and exacerbates respiratory symptoms. PMID:25082419

To establish trends in frequency of serious spinal cord injuries in rugby and rugby league over a 20 year period and to elucidate patterns of injury from retrospective analysis of cases admitted to New Zealand's two spinal injuries units. A detailed survey of unit records with follow-up of selected patients; statistical analysis of data. During the 20 years 1976 to 1995, 119 rugby and 22 rugby league players (total 141) were admitted to New Zealand's two spinal injuries units suffering serious spinal injuries and 47 of these became permanently confined to wheelchairs. There was a steady increase in frequency throughout the period studied. Of the injuries 83% occurred in forwards and 17% in backs. In rugby it was the scrum which produced most injuries, and in rugby league it was the tackle. The early season month of April produced most spinal injuries. In the eighteen months since intense compulsory educational programmes on safety were introduced by the New Zealand Rugby Union there have been no serious spinal cord injuries from rugby scrums. Contrary to widespread belief, there has not been a decrease in spinal cord injuries in rugby following rule changes in the mid 1980s. The information produced by this retrospective study has been an effective educational platform to make rugby and rugby league safer.

Emergency services manage trauma patients frequently and falls from height comprise the main cause of emergency service admissions. In this study, we aimed to analyse the demographic characteristics of falls from height and their relationship to the mortality. A total of 460 patients, who admitted to the Emergency Department of Inonu University between November 2011 and November 2014 with a history of fall from height, were examined retrospectively. Demographic parameters, fall characteristics and their effect to mortality were evaluated statistically. The study comprised of 292 (63.5%) men and 168 (36.5%) women patients. The mean age of all patients was 27±24.99 years. Twenty-six (5.6%) patients died and the majority of them were in ≥62 years old group. The highest percentage of falls was at 0-5 years age group (28.3%). People fell mainly from 1.1-4 metres(m) level (46.1%). The causes of falls were ordered as unintentional (92.2%), workplace (8.1%) and suicidal (1.7%). Skin and soft tissue injuries (37.4%) were the main traumatic lesions. Age, fall height, fall place, lineer skull fracture, subarachnoidal hemorrhage, cervical fracture, thoracic vertebra fracture and trauma scores had statistically significant effect on mortality. The casualties died because of subarachnoid hemorrhage mostly.

To investigate the risk of hypothyroidism after radioiodine (131I) treatment for hyperfunctioning thyroid nodules. Retrospective analysis of patients treated with 131I for hyperfunctioning thyroid nodules and followed up for a maximum of 20 years. A total of 346 patients treated with 131I in the years 1975-95, for a single hyperfunctioning nodule. Hypothyroidism was defined as TSH levels > 3.7 mU/l. Kaplan-Meier survival analysis was used to analyse permanence of euthyroidism after 131I. A stepwise Cox proportional hazard model was used to identify factors influencing the progression to hypothyroidism. The cumulative incidence of hypothyroidism was 7.6% at 1 year, 28% at 5 years, 46% at 10 years and 60% at 20 years. Age (P < 0.01), 24-th 131I uptake (P < 0.05) and previous treatment with methimazole (MMI, P < 0.1) were associated with a faster progression towards hypothyroidism, while thyroid and nodule size, thyroid status at diagnosis and degree of extranodular thyroid parenchymal suppression had no influence. In hyperthyroid patients with partial parenchymal suppression, however, previous MMI treatment was the most important prognostic factor (P < 0.01). After 20 years of follow-up, 60% of patients treated with 131I for a single hyperfunctioning nodule are hypothyroid. Factors increasing the risk of hypothyroidism are age, 131I uptake and MMI pretreatment. The prognostic value of this last factor, however, depends on the degree of suppression of the extranodular thyroid parenchyma at the scan.

The incidence of type 1 diabetes mellitus (T1DM) is increasing rapidly worldwide for children of every age group. A retrospective analysis of hospital registration data from five tertiary hospitals in Beijing, China, identified 485 patients (210 boys, 275 girls) younger than 15 years of age with newly diagnosed T1DM between 1995 and 2010. From 1995 to 2010, the incidence of T1DM in patients <15 years of age ranged from 0.935-3.26 per 100,000 per year. During this period, the average age-standardized incidence rate was 1.7 per 100,000 per year, and the average annual increase in T1DM incidence was 4.36%. The highest rate increases occurred in boys and in patients <5 years of age. For both genders and all age groups, T1DM incidence increased at an accelerated rate after 2006. By 2020, the incidence of T1DM among children in Beijing is projected to increase by a factor of 1.69. The incidence of T1DM among patients younger than 15 years of age in Beijing increased from 1995 to 2010, with rates growing at an accelerated pace since 2006. Based on recent trends, we project continued rapid growth in the number of new childhood T1DM cases in Beijing.

Socioeconomic status (SES) is a well-established determinant of health status and home ownership is a commonly used composite indicator of SES. Patients in low-income households often stay in public rental housing. The association between public rental housing and mortality has not been examined in Singapore. A retrospective, cohort study was conducted involving all patients who utilized the healthcare facilities under SingHealth Regional Health (SHRS) Services in Year 2012. Each patient was followed up for 5 years. Patients who were non-citizens or residing in a non-SHRS area were excluded from the study. A total of 147,004 patients were included in the study, of which 7252 (4.9%) patients died during the study period. The mean age of patients was 50.2 ± 17.2 years old and 7.1% (n = 10,400) of patients stayed in public rental housing. Patients who passed away had higher utilization of healthcare resources in the past 1 year and a higher proportion stayed in public rental housing (p < 0.001). They also had higher rates of co-morbidities such as hypertension, hyperlipidaemia and diabetes. (p < 0.001) After adjustment for demographic and clinical covariates, residence in public rental housing was associated with increased risk of all-cause mortality (Adjusted hazard ratio: 1.568, 95% CI: 1.469-1.673). Public rental housing was an independent risk factor for all-cause mortality. More studies should be conducted to understand health-seeking behavior and needs of public rental housing patients, to aid policymakers in formulating better plans for improving their health outcomes.

The study aim was to evaluate pharmacotherapy effects and long-term seizure outcomes in patients with juvenile absence epilepsy (JAE) during a five-year follow-up period. The secondary aim was to identify factors from patient history and determine their influence on seizure control. We retrospectively studied 46 patients with JAE in the period between 2006 and 2011. The age at seizure onset, onset seizure type, family history of epilepsy, status epilepticus in history, medication history, and the rate of seizure control were studied. There were 30 females (65.2%) and 16 males (34.8%) in the study. The mean age at seizure onset was 12.9±5.6 years (ranged from 3 to 28 years). In 30 patients (65.2%), seizure onset was with absences, in 15 patients (32.6%) with generalized tonic-clonic seizure (GTCS), and in 1 patient (2.2%) with absence status. In 43 patients (93.5%), GTCS occurred in the course of the disease. Family history for epilepsy was positive in 10 patients (21.7%). In the five-year follow-up period, seizure freedom (Group 1) was achieved in 7 patients (15.2%). In total, 22 patients (47.8%) were classified into the groups involving very poor seizure control and antiepileptic drug resistance (Groups 5 and 6). The mean number of antiepileptic drugs (AEDs) used in the course of the disease in appropriate therapeutic doses was 3.8±2.3 (1-10 AEDs). The study results show that almost half of JAE patients have poor seizure control with a high rate of pharmacoresistance. The outcome of JAE can be very uncertain.

Nowadays, the entire manufacturing process is based on the current GMPs, which emphasize the reproducibility of the process, and companies have a lot of recorded data about their processes. The establishment of the design space (DS) from retrospective data for a wet compression process. A design of experiments (DoE) with historical data from 4 years of industrial production has been carried out using the experimental factors as the results of the previous risk analysis and eight key parameters (quality specifications) that encompassed process and quality control data. Software Statgraphics 5.0 was applied, and data were processed to obtain eight DS as well as their safe and working ranges. Experience shows that it is possible to determine DS retrospectively, being the greatest difficulty in handling and processing of high amounts of data; however, the practicality of this study is very interesting as it let have the DS with minimal investment in experiments since actual production batch data are processed statistically.

The purpose of this retrospective study was to determine the frequency of occurrence of oculomotor dysfunctions in a sample of ambulatory outpatients who have acquired brain injury (ABI), either traumatic brain injury (TBI) or cerebrovascular accident (CVA), with associated vision symptoms. Medical records of 220 individuals with either TBI (n = 160) or CVA (n = 60) were reviewed retrospectively. This was determined by a computer-based query spanning the years 2000 through 2003, for the frequency of occurrence of oculomotor dysfunctions including accommodation, version, vergence, strabismus, and cranial nerve (CN) palsy. The majority of individuals with either TBI (90%) or CVA (86.7%) manifested an oculomotor dysfunction. Accommodative and vergence deficits were most common in the TBI subgroup, whereas strabismus and CN palsy were most common in the CVA subgroup. The frequency of occurrence of versional deficits was similar in each diagnostic subgroup. These new findings should alert the clinician to the higher frequency of occurrence of oculomotor dysfunctions in these populations and the associated therapeutic, rehabilitative, and quality-of-life implications.

Past research with the Berkeley Adult Attachment Interview demonstrates that retrospectively defined earned-secures (who coherently describe negative childhood experiences) parent as effectively as do continuous-secures (who coherently describe positive childhood experiences), but manifest liabilities in the form of depressive symptomatology. This article presents data from a 23-year longitudinal study that replicate and extend prior research, testing a key premise that earned-secures so defined actually have a history of insecure attachments that change over time and/or endure consistently harsh or ineffective parenting in their youth. Discrepant with assumptions, retrospective earned-secures were not more likely than continuous-secures to have been anxiously attached in infancy and were observed in childhood and adolescence to have encountered among the most supportive and structured maternal parenting in a high-risk sample. Prospectively defined earned-secures (operationalized using participants' infant attachment classifications) did indeed go on to have success in their close relationships, many without reporting relatively high levels of internalizing distress in adulthood.

Can cemented dual-mobility cups be used without a reinforcement device in cases of mild acetabular bone stock alteration in total hip arthroplasty?

Cemented versions of dual-mobility cups (DMCs), helpful in cases of bone stock alteration, are usually used in association with a reinforcement device. To simplify the intervention in elderly subjects or those with a poor bone stock, the cups can be cemented directly into the bone, but the long-term result remains uncertain. We conducted a retrospective study in this population so as to: (1) assess whether cemented fixation of a DMC without a reinforcement device leads to a higher loosening rate, (2) confirm its efficacy in preventing dislocations in subjects at high risk of instability, and (3) measure the functional results. Cemented fixation of a DMC is reliable in cases of moderate alteration of bone stock. Sixty-four patients (66 hips) undergoing implantation of a cemented DMC (Saturne™) without a reinforcement device were included in this single-center retrospective study. Their mean age was 79.8 years (range, 40-95 years). The indications varied: hip osteoarthritis (30.3%), prosthesis revision (44.0%), and trauma (25.8%). The patients were evaluated radiologically and clinically at follow-up. The main evaluation criterion was the revision rate for aseptic loosening. Dislocations, the infection rate, and the Postel Merle d'Aubigné (PMA) score were noted. At the mean follow-up of 4.2 years, three (4.6%) patients had been lost to follow-up and 22 (33.3%) had died. There was one case of aseptic loosening (1.5%). Cup survival was 98% at 5 years (95%CI [94-100]). There were no dislocations. There was one revision for infection. The mean PMA score was 15.5 (range, 9-18). The frequency of acetabular loosening was comparable to the frequency in cemented DMCs with a reinforcement device. A cemented DMC without a reinforcement device is possible and is a simple and viable option when there is moderate bone stock alteration. IV, retrospective cohort study.

the main objective was to evaluate if the admission functional independence measure (FIM) score could be used to predict the risk of falls in geriatric inpatients. a 10-year retrospective study was performed. the study was conducted in a 298-bed geriatric teaching hospital in Geneva, Switzerland. all patients discharged from the hospital from 1 January 1997 to 31 December 2006 were selected. measures used were FIM scores at admission using the FIM instrument and number of falls extracted from the institution's fall report forms. during the study period, there were 23,966 hospital stays. A total of 8,254 falls occurred. Of these, 7,995 falls were linked to 4,651 stays. Falls were recorded in 19.4% of hospital stays, with a mean incidence of 7.84 falls per 1,000 patients-days. Although there was a statistically significant relationship between total FIM score, its subscales, and the risk of falling, the sensitivity, specificity, positive predictive value and negative predictive value obtained with receiver operating characteristic curves were insufficient to permit fall prediction. This might be due in part to a non-linear relationship between FIM score and fall risk. in this study, the FIM instrument was found to be unable to predict risk of falls in general geriatric wards.

How many patients in Denmark were treated with fertility-sparing surgery (FSS) for epithelial ovarian cancer (EOC) and what was their prognosis compared with patients treated with radical surgery (RS)? This study was a retrospective Danish nationwide study, evaluating the effect of FSS compared with RS in patients with EOC, age ≤45 years and International Federation of Gynecology and Obstetrics (FIGO) stage ≤IC3 from 2005 to 2016. A total of 106 patients were included. Of these, 13 were treated with FSS and 93 were treated with RS. Median age was 27 versus 42 years (P < 0.0001). Overall survival did not differ significantly between the two groups. Overall survival rate in the FSS group was 100%, while the overall survival in the RS group was 87%. Disease-specific survival was 100% in the FSS group and 91% in the RS group. This study shows that patients treated with FSS for FIGO stage I EOC do not have an impaired survival compared with patients treated with RS. Nevertheless, the conclusion must be interpreted with caution due to the limited number of patients and the retrospective nature of the study. Larger studies are needed before conclusions can be drawn. Copyright © 2018. Published by Elsevier Ltd.

Objectives: Data reflecting cardiopulmonary resuscitation (CPR) efforts in Saudi Arabia are limited. In this study, we analyzed the characteristics, and estimated the outcome, of in-hospital CPR in a teaching hospital in Saudi Arabia over 4 years. Methods: A retrospective, observational study was conducted between January 2009 and December 2012 and included 4361 patients with sudden cardiopulmonary arrest. Resuscitation forms were reviewed. Demographic data, resuscitation characteristics, and survival outcomes were recorded. Results: The mean ± standard deviation age of arrested patient was 40 ± 31 years. The immediate survival rate was 64%, 43% at 24 h, and 30% at discharge. The death rate was 70%. Respiratory type of arrest, time and place of arrest, short duration of arrest, witnessed arrest, the use of epinephrine and atropine boluses, and shockable arrhythmias were associated with higher 24-h survival rates. A low survival rate was found among patients with cardiac types of arrest, and those with a longer duration of arrest, pulseless electrical activity, and asystole. Comorbidities were present in 3786 patients with cardiac arrest and contributed to a poor survival rate (P < 0.001). Conclusions: The study confirms the findings of previously published studies in highly developed countries and provides some reflection on the practice of resuscitation in Saudi Arabia.

The aim of this study was to evaluate the incidence and the risk factors of osteonecrosis of the jaw (ONJ) in a group of patients treated with zoledronic acid (ZA) for bone metastases from solid tumors and enrolled in a preventive dental program. This 5-year retrospective longitudinal study included all consecutive oncological patients who underwent at least one infusion with ZA between 2004 and 2011 for bone metastases due to solid neoplasms. Of the 156 patients enrolled in the study, 17 developed ONJ (10.89%). At the multivariate analysis, severe periodontal disease (P=0.025), tooth extraction (P<0.0001) and starting the preventive dental program after the beginning of ZA therapy (P=0.02) were the only factors which showed a significant association with the occurrence of ONJ. This study demonstrated the importance of beginning dental prevention before zoledronic acid exposure in reducing ONJ occurrence, especially in the long term. The results of this research show that control of periodontal disease and an increase in the time between tooth extraction and the first ZA administration are recommended in order to reduce the risk of ONJ development.

This retrospective study analyzes post-mortem examination data of 164 firearm-related casualties recorded by the Brescia, Italy Institute of Forensic Medicine between the years 1994 and 2006. The following variables were considered: year, month and day of death, gender and age of the victim, manner of death (homicide, suicide, accidental), type of weapon used, anatomical site and number of wounds, scene of death, and, whenever requested by the local District Attorney's Office, results of the toxicological examinations conducted on the corpses of the deceased. In the County of Brescia, Italy, the 2006 firearm-related mortality rate amounted to 0.84 per 100,000 residents, with an average of 12.6 cases per year. The most common manner of death was suicide (60.4%), followed by homicide (35.9%) and accidental death (3.7%). Most victims were male, with an average age of 47.2 in cases of suicide, 37.9 in cases of homicide, and 47.5 in cases of accidental death. Considering all of the death manners contemplated in this study, the weapon types most frequently resorted to were single-action, short-barrelled guns, followed by multiple-action, long-barrelled ones. In cases of suicide, entry wounds were primarily situated on the head (right temple) and chest (precordium), while in cases of homicide no conclusions could be drawn as to the entry wounds' predominant location.

It is generally recommended that patients with splanchnic vein thrombosis (SVT) should receive a minimum of 3 months of anticoagulant treatment. However, little information is available on the long-term risk of recurrent thrombotic events. The aim of this study was to evaluate the risk of venous and arterial thrombosis after discontinuation of vitamin K antagonist (VKA) in SVT patients. Retrospective information from a cohort of SVT patients treated with VKA and followed by 37 Italian Anticoagulation Clinics, up to June 2013, was collected. Only patients who discontinued VKA and did not receive any other anticoagulant drug were enrolled in this study. Thrombotic events during follow-up were centrally adjudicated. Ninety patients were included: 33 unprovoked SVT, 27 SVT secondary to transient risk factors, and 30 with permanent risk factors. During a median follow-up of 1.6 years, 6 venous and 1 arterial thrombosis were documented, for an incidence of 3.3/100 patient-years (pt-y). The recurrence rate was highest in the first year after VKA discontinuation (8.2/100'pt-y) and in patients with permanent risk factors (10.2/100'pt-y). Liver cirrhosis significantly increased the risk of recurrence. In conclusion, the rate of recurrent vascular complications after SVT is not negligible, at least in some patient subgroups.

The screening of anti-Human Immunodeficiency Virus antibodies is mandatory in every blood donor admitted to the Blood Bank of Kinshasa University Clinics since 1984. However, no compiled data are available to date. The objective of this study was to establish the trend, prevalence, viral co-infections, and determinants of Human Immunodeficiency anti-Virus serology in blood donors admitted between 2003-2006 and 2008-2013. A retrospective analysis was carried out at University Kinshasa Clinics, using blood donors' records during 2003-2006 and 2008-2013. The prevalence of the human immunodeficiency virus per year, age, sex and type of blood donors were estimated. Independent predictors of human immunodeficiency virus seropositivity were also identified. Out of 26,341 blood donors, 2.2% (n=576/26,341) were seropositive for Human Immunodeficiency Virus. Age<25 years (OR=1.7; 95% CI: 1.4-2; P<0.0001) and Hepatitis C virus seropositivity (OR=3; 95% CI; 1.8-4.9; P<0.001) emerged as independent predictors of Human Immunodeficiency Virus seropositivity. This study shows a strong association between the Human Immunodeficiency Virus and hepatitis C and younger age respectively. Further studies are needed to ensure safety of Blood donation in Democratic Republic of Congo. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Since the first description of infective endocarditis, the profile of the disease has evolved continuously with stable incidence. However, epidemiological features are different in developing countries compared with western countries. To describe epidemiological, microbiological and outcome characteristics of infective endocarditis in Tunisia. This was a descriptive multicenter retrospective study of inpatients treated for infective endocarditis from 1991 to 2000. Charts of patients with possible or definite infective endocarditis according to the Duke criteria were included in the study. Four hundred and forty episodes of infective endocarditis among 435 patients (242 males, 193 females; mean (SD) age=32.4 (16.8) years, range 1-78 years) were reviewed. The most common predisposing heart disease was rheumatic valvular disease (45.2%). Infective endocarditis occurred on prosthetic valves in 17.3% of cases. Causative microorganisms were identified in 50.2% of cases: streptococci (17.3%), enterococci (3.9%), staphylococci (17.9%), and other pathogens (11.1%). Blood cultures were negative in 53.6% and no microorganism was identified in 49.8%. Early valve surgery was performed in 51.2% of patients. The in-hospital mortality was 20.6%. Infective endocarditis is still frequently associated with rheumatic disease among young adults in Tunisia, with a high frequency of negative blood cultures and high in-hospital mortality, given that the population affected is relatively young.

Antipsychotics are commonly used to manage behavioral and psychological symptoms of dementia. Concerns over their safety and efficacy in this role have resulted in antipsychotics typically being recommended for short-term usage only when used among dementia patients. However, there is little work examining the duration of antipsychotic treatment in the elderly dementia patient population. To determine the persistence of use of antipsychotics in elderly dementia patients and the role of dose on therapy duration. A retrospective, population-based cohort study using administrative data, including dispensing records from a provincial public drug program, from Ontario, Canada between 2009 and 2012. Elderly dementia patients newly initiated onto antipsychotics were followed until drug discontinuation, death, 2-year follow-up, or end of study. Competing risk analysis was performed to determine time to discontinuation, stratified by categories of initial dose. After 2 years 49.1 % of the cohort ( N  = 22,927 of 46,695) had discontinued treatment. When stratified by dose, the high-dose group (51.1 % discontinued) discontinued more frequently than the medium- (48.7 % discontinued) and low- (47.5 % discontinued) dose groups ( p  < 0.0001). Approximately half of elderly dementia patients treated with antipsychotics discontinue within 2 years, with those on higher doses more likely to discontinue. However, the number of patients remaining on therapy represents a serious public health concern.

To further understand management of pediatric patients with multiple sclerosis (MS), we examined disease features, clinical practice patterns, and response to treatment in the United States (US) and seven other countries ('rest of World'; ROW). Anonymized data, recorded as part of routine clinical practice, were obtained from medical records (1997-2009) of study participants (who received subcutaneous interferon β-1a before age 18 years) from the US and ROW. Samples were stratified by age (preadolescents [<12 years] and adolescents [12-17 years]). US adolescents had a higher mean body mass index versus ROW adolescents (BMI; 27.2 versus 22.5 kg/m(2)), started disease-modifying therapy (DMT) earlier after the first relapse, were more likely to have received a DMT before initiating subcutaneous interferon β-1a, had a higher relapse rate, and were more likely to switch from subcutaneous interferon β-1a to another DMT before the end of the observation period. This retrospective analysis of a multinational sample of pediatric MS patients who received subcutaneous interferon β-1a found that those from the US had higher BMI, relapsed more frequently, and were managed differently, compared with ROW patients. Future prospective studies are needed to confirm these observations and ascertain their clinical significance. Copyright © 2016 The Authors. Published by Elsevier B.V. All rights reserved.

Bronchiectasis is characterized by abnormal, permanent and irreversible dilatation of the bronchi, usually responsible for daily symptoms and frequent respiratory complications. Many causes have been identified, but only limited data are available concerning the association between bronchiectasis and renal transplantation. We conducted a retrospective multicenter study of cases of bronchiectasis diagnosed after renal transplantation in 14 renal transplantation departments (French SPIESSER group). Demographic, clinical, laboratory and CT scan data were collected. Forty-six patients were included (mean age 58.2 years, 52.2 % men). Autosomal dominant polycystic kidney disease (32.6 %) was the main underlying renal disease. Chronic cough and sputum (50.0 %) were the major symptoms leading to chest CT scan. Mean duration of symptoms before diagnosis was 1.5 years [0-12.1 years]. Microorganisms were identified in 22 patients, predominantly Haemophilus influenzae. Hypogammaglobulinemia was observed in 46.9 % patients. Bronchiectasis was usually extensive (84.8 %). The total bronchiectasis score was 7.4 ± 5.5 with a significant gradient from apex to bases. Many patients remained symptomatic (43.5 %) and/or presented recurrent respiratory tract infections (37.0 %) during follow-up. Six deaths (13 %) occurred during follow-up, but none were attributable to bronchiectasis. These results highlight that the diagnosis of bronchiectasis should be considered in patients with de novo respiratory symptoms after renal transplantation. Further studies are needed to more clearly understand the mechanisms underlying bronchiectasis in this setting.

Residual bacterial biofilm and/or bacteria in planktonic form may be survived in the bone following an extraction of an infected tooth that was endodontically treated unsuccessfully Failed endodontic treatment may be associated with failure of implants to osseointegrate in the same sites. Therefore, the aim of this retrospective case-control study is to examine the risk of implant failure in previous failed endodontic sites. This retrospective case-control study is based on 94 dental records of implants placed at the University of Minnesota School of Dentistry. Dental records of patients who received an implant in sites with previously failed endodontic therapy in the dental school were identified from the electronic database, while control subjects were obtained from the same pool of patients with the requirement to have received an implant in a site that was not endodontically treated. The mean age of the population was 62.89±14.17 years with 57.4% of the sample being females and 42.6% of them being males. In regards to the socio-economic status and dental insurance, 84.0% of this population was classified as low socio-economic status and 68.1% had dental insurance. Tobacco use was self-reported by 9.6% and hypercholesterolemia was the most prevalent systemic medical condition. Dental implant failure was identified in two of the included records (2.1%), both of which were placed in sites with a history of failed endodontic treatment. Within the limitations of this retrospective case-control study, further investigation with a larger population group into implant failure of sites that previously had unsuccessful endodontic treatment would be warranted. Implant failure may be associated with a history of failed endodontic treatment. Key words: Implantology, endodontics, osseointegration, treatment outcome, case-control study.

The authors retrospectively evaluated 33 eye injuries due to metal missiles in 31 patients presenting to our emergency center over the last 3 years. Injuries occurred most frequently when the patients were grinding metal or working on their cars. The type of metal involved in the injury often dictates the type of ophthalmic reaction that will occur. A discussion of intraocular metallic foreign bodies with an emphasis on electroretinograms and metal analysis is presented.

To assess the profile and describe the clinical presentations and complications of childhood leprosy in a tertiary care hospital in North Kerala, South India during 2003-2012 and to analyse any change in the age-sex profile and the clinical pattern of leprosy in children below the age of 15 years over the 10-year study period. A retrospective descriptive study of children less than 15 years of age diagnosed with leprosy and registered for treatment in a tertiary care institution from 2003 to 2012. Demographic, clinical, investigative and treatment data were collected using a pre-set proforma. 138 (12.1%) of the total 1143 leprosy cases registered for treatment during the 10-year period were below 15 years of age. The 10-year study period witnessed a statistically insignificant decrease in the new childhood leprosy cases registered for treatment in our tertiary care institution. The majority of cases belonged to the 6-12 year age group (61.6%) with a male predominance. Borderline tuberculoid (BT) was the commonest clinical type (65.9%) followed by indeterminate leprosy (18.8%); 101 patients required paucibacillary (PB) and 37 needed multibacillary (MB) treatment. The number of patients requiring MB treatment showed a statistically significant increase and there was a significant decline in number of cases requiring PB treatment. During the entire study period no Type 2 lepra reaction was documented in patients below Hema 15 years and only two patients manifested Type 1 reaction. Ten (7.2%) out of the 138 patients were cases of relapse. There was a clear female predilection among relapse cases with the majority belonging to the adolescent age. Childhood leprosy still contributes to a significant proportion of the total case load denoting the continuing active horizontal transmission of leprosy. The rise in number of patients with more extensive disease in the background of declining disease prevalence is suggestive of the delay in diagnosis and treatment. A high relapse rate noted in the present study may be due to incorrect classification and treatment of MB as PB leprosy which in turn might have resulted in treatment failure due to inadequate treatment.

Several studies reported the efficacy of orthokeratology for myopia control. Somehow, there is limited publication with follow-up longer than 3 years. This study aims to research whether overnight orthokeratology influences the progression rate of the manifest refractive error of myopic children in a longer follow-up period (up to 12 years). And if changes in progression rate are found, to investigate the relationship between refractive changes and different baseline factors, including refraction error, wearing age and lens replacement frequency. In addition, this study collects long-term safety profile of overnight orthokeratology. This is a retrospective study of sixty-six school-age children who received overnight orthokeratology correction between January 1998 and December 2013. Thirty-six subjects whose baseline age and refractive error matched with those in the orthokeratology group were selected to form control group. These subjects were followed up at least for 12 months. Manifest refractions, cycloplegic refractions, uncorrected and best-corrected visual acuities, power vector of astigmatism, corneal curvature, and lens replacement frequency were obtained for analysis. Data of 203 eyes were derived from 66 orthokeratology subjects (31 males and 35 females) and 36 control subjects (22 males and 14 females) enrolled in this study. Their wearing ages ranged from 7 years to 16 years (mean ± SE, 11.72 ± 0.18 years). The follow-up time ranged from 1 year to 13 years (mean ± SE, 6.32 ± 0.15 years). At baseline, their myopia ranged from -0.5 D to -8.0 D (mean ± SE, -3.70 ± 0.12 D), and astigmatism ranged from 0 D to -3.0 D (mean ± SE, -0.55 ± 0.05 D). Comparing with control group, orthokeratology group had a significantly (p < 0.001) lower trend of refractive error change during the follow-up periods. According to the analysis results of GEE model, greater power of astigmatism was found to be associated with increased change of refractive error during follow-up years. Overnight orthokeratology was effective in slowing myopia progression over a twelve-year follow-up period and demonstrated a clinically acceptable safety profile. Initial higher astigmatism power was found to be associated with increased change of refractive error during follow-up years.

Patients with chronic thromboembolic pulmonary hypertension (CTEPH) require lifelong anticoagulation therapy. However, the bleeding risk and recurrence of venous thromboembolism (VTE) in CTEPH patients who are administered warfarin have not been adequately evaluated. The purpose of this study was to evaluate the risk of clinically relevant bleeding, recurrent VTE, and clinical worsening in patients with CTEPH who were administered warfarin. The clinical records of 72 patients with CTEPH who regularly visited our institution and were administered warfarin were retrospectively reviewed between 1 January 2011 and 31 December 2015. We investigated the incidence of clinically relevant bleeding events, recurrent VTE, and hospitalization for the deterioration of pulmonary hypertension or right heart failure (RHF) during the observation period. The mean observation period for the 72 patients was 3.60 ± 1.60 person-years. Clinically relevant bleeding, RHF, and recurrent VTE occurred in 21 (29.2%), eight (11.1%), and three (4.2%) of 72 patients, respectively, and the incidence rates for these events were 8.1%/person-year, 3.1%/person-year, and 1.2%/person-year, respectively. The incidence rates for the major and non-major bleeding events were 5.0%/person-year and 3.9%/person-year, respectively. The incidence of clinically relevant bleeding events was 20.8%/person-year during medical treatment with a soluble guanylate cyclase stimulator. One of 35 patients (2.9%) during the post-pulmonary endarterectomy period experienced hemoptysis during observation period (> 6 months after pulmonary endarterectomy). No bleeding events occurred during the post-balloon pulmonary angioplasty period. In conclusion, warfarin effectively prevents VTE recurrence in CTEPH patients, but its effects may be associated with a considerable bleeding risk. PMID:28604280

Radiation dose to the eye lens is a crucial issue for interventional cardiologists (ICs) who are exposed during the procedures they perform. This paper presents a retrospective assessment of the cumulative eye lens doses of ICs enrolled in the O'CLOC study for Occupational Cataracts and Lens Opacities in interventional Cardiology. Information on the workload in the catheterisation laboratory, radiation protection equipment, eye lens dose per procedure and dose reduction factors associated with eye-protective equipment were considered. For the 129 ICs at an average age of 51 who had worked for an average period of 22 years, the estimated cumulative eye lens dose ranged from 25 mSv to more than 1600 mSv; the mean ± SD was 423 ± 359 mSv. After several years of practice, without eye protection, ICs may exceed the new ICRP lifetime eye dose threshold of 500 mSv and be at high risk of developing early radiation-induced cataracts. Radiation protection equipment can reduce these doses and should be used routinely.

The aim of the study was to describe temporal changes in bipolar disorder during 20 years within the Swedish population and to investigate clinical and socioeconomic characteristics, drug treatment, and mortality among patients with bipolar disorder. We conducted a retrospective, nationwide registry study (the Swedish Population Register) that included all patients diagnosed with bipolar disorder (1991-2010) and linked individual data from the Swedish National Patient Register, the National Prescribed Drug Register, and the Population Register (NCT01455961). A cross-sectional cohort analysis was performed for years 2006 versus 2009. Data were analyzed using descriptive statistics. During the study period, the annual incidence of diagnosed bipolar disorder increased 3.5-fold, and patients were diagnosed at a younger age. Mortality among patients with bipolar disorder was twice that of the general population. Compared to an age-standardized population, 30% fewer patients with bipolar disorder were available for work. Among the 40% employed, 64% reported sick leave (46% >100 days/year). Despite similar education levels, disposable income was lower compared to the general population. The most commonly preceding psychiatric diagnoses were depressive or anxiety disorders. Comparing the data for 2006 and 2009 demonstrated similar somatic comorbidity burdens and socioeconomic levels. There was also a decrease in dispensed antipsychotic medications and lithium, while antiepileptic prescriptions increased slightly. Antidepressant dispenses remained virtually unchanged. In Sweden, the incidence and prevalence of diagnosed bipolar disorder have increased during the last 20 years. Compared to the general population, these patients had similar education levels, lower employment levels, less disposable income, more sick leave, and twice the mortality. A trend towards earlier diagnosis, more use of antidepressants, and less use of lithium was seen. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To compare healthcare costs and utilization among participants in a study of two active lifestyle interventions implemented in the workplace and designed to foster awareness of and attention to health with a propensity score matched control group. We retrospectively compared changes in healthcare (HC) utilization among participants in the mindfulness intervention (n=84) and the diet/exercise intervention (n=86) to a retrospectively matched control group (n=258) drawn for this study. The control group was matched from the non-participant population on age, gender, relative risk score, and HC expenditures in the 9 month preceding the study. Measures included number of primary care visits, number and cost of pharmacy prescriptions, number of hospital admissions, and overall healthcare costs tracked for 5 years after the intervention. Significantly fewer primary care visits (p<.001) for both intervention groups as compared to controls, with a non-significant trend towards lower overall HC utilization (4,300.00 actual dollar differences) and hospital admissions for the intervention groups after five years. Pharmacy costs and number of prescriptions were significantly higher for the two intervention groups compared to controls over the five years (p<0.05), yet still resulted in less HC utilization costs, potentially indicating greater self-management of care. This study provides valuable information as to the cost savings and value of providing workplace lifestyle interventions that focus on awareness of one's body and health. Health economic studies validate the scale of personal and organization health cost savings that such programs can generate. Copyright © 2016 Elsevier Ltd. All rights reserved.

This retrospective study attempted to identify the pattern of ambulance calls for the past two years at the Hospital Universiti Sains Malaysia (HUSM) and Hospital Kota Bharu (HKB). This study will provide a simple method of acquiring information related to ambulance response time (ART) and to test whether it met the international standards and needs of the client. Additionally, this paper takes into account the management of emergency calls. This included ambulance response time, which was part of Emergency Medical Services (EMS) episode: onset of ART, which started when details like phone number of the caller, exact location of the incident and the nature of the main complaint had been noted. ART ended when the emergency team arrived at the scene of incident. Information regarding ambulance calls from the record offices of HUSM and HKB was recorded for the year 2001 and 2002, tabulated and analyzed. There was a significant difference in the total number of calls managed by HUSM and HKB in the year 2001. It was noted that 645 calls were managed by HUSM while 1069 calls were recorded at HKB. In the year 2002, however, HUSM led with 613 extra numbers of calls as compare to HKB with 1193 numbers of calls. The pattern of ambulance calls observed is thought to possibly be influenced by social activities like local festivities, school holidays and the seasons. Further, it is observed that no studies were previously undertaken to compare the ART at both the HUSM and HKB to that of the international standards. In fact, a literature review undertaken so far showed no similar studies have been done for the whole Malaysia. PMID:22605956

Background Hispanic patients undergoing long-term dialysis experience better survival compared with non-Hispanic whites. It is unknown whether this association differs by age, has changed over time, or is due to differential access to kidney transplantation. Study Design National retrospective cohort study. Setting & Participants Using the US Renal Data System, we identified 615,618 white patients 18 years or older who initiated dialysis therapy between January 1, 1995, and December 31, 2007. Predictors Hispanic ethnicity (vs non-Hispanic whites), year of end-stage renal disease incidence, age (as potential effect modifier). Outcomes All-cause and cause-specific mortality. Results We found that Hispanics initiating dialysis therapy experienced lower mortality, but age modified this association (P < 0.001). Compared with non-Hispanic whites, mortality in Hispanics was 33% lower at ages 18–39 years (adjusted cause-specific HR [HRcs], 0.67; 95% CI, 0.64–0.71) and 40–59 years (HRcs, 0.67; 95% CI, 0.66–0.68), 19% lower at ages 60–79 years (HRcs, 0.81; 95% CI, 0.80–0.82), and 6% lower at 80 years or older (HRcs, 0.94; 95% CI, 0.91–0.97). Accounting for the differential rates of kidney transplantation, the associations were attenuated markedly in the younger age strata; the survival benefit for Hispanics was reduced from 33% to 10% at ages 18–39 years (adjusted subdistribution-specific HR [HRsd], 0.90; 95% CI, 0.85–0.94) and from 33% to 19% among those aged 40–59 years (HRsd, 0.81; 95% CI, 0.80–0.83). Limitations Inability to analyze Hispanic subgroups that may experience heterogeneous mortality outcomes. Conclusions Overall, Hispanics experienced lower mortality, but differential access to kidney transplantation was responsible for much of the apparent survival benefit noted in younger Hispanics.

With improvement in survival, it is important to evaluate the impact of treatment on secondary cancers in acute lymphoblastic leukaemia (ALL) survivors. A retrospective cohort study comprising 2918 children diagnosed with ALL and enrolled on Tokyo Children's Cancer Study Group (TCCSG) protocols between 1984 and 2005 was conducted to evaluate the incidence of secondary cancers and associated factors including treatment protocol, cranial irradiation and other characteristics of the primary ALL. Thirty-seven patients developed secondary cancers, including acute myeloid leukaemia (n = 11), myelodysplastic syndrome (n = 5), non-Hodgkin lymphoma (n = 2), brain tumours (n = 13) and other solid carcinomas (n = 6) within a median follow-up duration of 9·5 years. The cumulative incidence of any secondary cancers was 1·0% (95% confidence interval (CI), 0·7-1·4%) at 10 years and 2·4% (95% CI, 1·5-3·7%) at 20 years, respectively. Standardized incidence rate ratio of secondary cancers was 9·3 (95% CI, 6·5-12·8). Multivariate analyses showed an increased risk of secondary cancers associated with the recent treatment protocol and cranial irradiation. There was no evidence of a reduction in secondary cancer incidence despite marked decreases in cranial irradiation use in the recent protocols. © 2013 John Wiley & Sons Ltd.

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

The presentation of scientific studies at major meetings serves to rapidly share study results with the scientific community. On the other hand, full-text publication of abstracts in peer-reviewed journals ensures the dissemination of science. This study examines the publication rate (PR) of meeting abstracts presented at the European Society for Surgical Research (ESSR) congresses and determines/compares the factors affecting the PRs. All presentations at the ESSR congresses held during 2008-2011 were retrospectively assessed. Manuscripts indexed in PubMed were included. The meeting year, journal impact factor (IF) in the publication year, study type, presentation type, time to publication and geographic origin of studies were assessed. Among a total of 1,368 oral and poster abstracts, 48.7% (n = 391) of the oral presentations (OPs) and 29.7% (n = 168) of the poster presentations (PPs) were published in medical journals indexed in PubMed. The mean IF of the journals was 2.696 (0.17-14.95). The journals that published OPs had a higher IF than the journals in which PPs were published (2.944 vs. 2.118; p < 0.001). The PR was also higher in the OP group than in the PP group of journals (p < 0.001). The time to publication was 17.5 months (-166 to 82) and was shorter for PPs than for OPs (14.02 vs. 19.09 months; p = 0.01). According to the study type, experimental studies had a significantly higher PR (53.7%; p < 0.001); however, there was no significant difference in PR in terms of the prospective or retrospective nature of clinical studies. The clinical studies were also compared according to the IF values of the journals in terms of the prospective or retrospective nature of the study, and no significant difference was found (p = 0.62). The ESSR congress is an efficient meeting for researchers from varied surgical disciplines and has a PR equivalent to that of similar scientific meetings. The congress has achieved a PR of 40.9% over 4 years with an average IF of 2.696 and a mean time to publication of 17.5 months, which is equivalent to that of similar scientific meetings. OPs have a higher PR in journals with greater IF values as compared with PPs. © 2016 S. Karger AG, Basel.

Atypical antipsychotics have been associated with weight gain. This study examines the efficacy of adjunctive topiramate in patients with schizophrenia and schizoaffective disorder with antipsychotic-induced weight gain. A 2-year retrospective case analysis was performed in all 300 patients of the outpatient Special Follow-up Clinic for chronic schizophrenia and related psychoses at the Allan Memorial Institute, McGill University Health Centre (Montreal, Canada), a tertiary care University teaching hospital. 10 patients met study inclusion criteria. Mean daily topiramate dose was 197.5 mg (A+/-77) (range, 125-400 mg). Topiramate produced continued weight loss throughout the study duration without tolerance. Patients treated for 6 months and more had significantly higher Body Mass Index (BMI) differences than those treated for shorter durations (BMI-d6 months=-4.7A+/-2.4; BMI-d2 months=-3.2A+/-2.3; P=0.015). BMI changes were similar across genders. This study supports topiramate use to target weight loss in stable overweight schizophrenic patients as a potential therapy that requires further investigation.

To investigate epidemiologic, clinical and pathologic aspects of various grades of vulvar intraepithelial neoplasia (VIN). A retrospective, multicenter study of 370 cases of vulvar intraepithelial neoplasia (VIN) was performed by the Italian Study Group on Vulvar Disease. Of the 370 cases, 148 were VIN 1 (40.0%, 53 were VIN 2 (14.3%), and 169 were VIN 3 (45.7%). The mean age of the patients was 52.6 years. During the study period an increase in the rate of human papillomavirus-associated VIN was observed. In addition, while VIN 1 and 2 were associated mostly with squamous cell hyperplasia, VIN 3 was almost equally associated with lichen sclerosus and squamous cell hyperplasia; the difference was statistically significant. Intraepithelial or invasive squamous neoplasia of the lower genital tract was associated in 22% of the cases (82/370). The results of the investigation, although not allowing firm conclusions due to the retrospective and multicentered nature of the study, demonstrate the extreme heterogeneity of VIN lesions.

Sarcopenia, defined as age-related loss of skeletal muscle mass and function, increases the risk of albuminuria. However, it has still unknown whether sarcopenia could increase the risk for the progression of albuminuria. A total 238 patients with type 2 diabetes (mean age 64 ± 12 years; 39.2% women) were studied in the present retrospective observational study. The prevalence of sarcopenia was 17.6%. During the median follow-up period of 2.6 years, albuminuria was measured 5.8 ± 1.8 times, and progression of albuminuria was observed in 14.9% of patients with normoalbuminuria, as was 11.5% in those with microalbuminuria. Sarcopenia was significantly associated with both progression (hazard ratio 2.61, 95% confidence interval 1.08-6.31, P = 0.034) and regression (hazard ratio 0.23, 95% confidence interval 0.05-0.98, P = 0.048) of albuminuria by multivariate Cox regression analysis. The present data suggest that sarcopenia is an important determinant of both progression and regression of albuminuria in patients with type 2 diabetes. © 2017 The Authors.

The Essure(®) system is a hysteroscopic sterilization method. The aim of our study is to retrospectively evaluate the sterilization procedure with Essure(®) devices, with and without anesthesia, and in particular with hypnosis. The descriptive study includes all tubal sterilization with Essure(®) performed during the year 2009 at the Maternité régionale de Nancy. Hypnosis efficiency is retrospectively evaluated with Verbal Numeric Rating Scale (VNRS) for peroperative pain, and analgesic medication use for postoperative pain. Ninety-four sterilizations are performed, 85% (85/94) of them without anesthesia. The mean VNRS is 3.0. The mean operative time is 8.7 minutes, positively correlated with the VNRS (P=0.0005). The rate of successful insertion is 94%. At 3 months, 91% of the implants have a correct location. Inadequate locations are more frequent when anesthesia have been performed (37% vs 4%, P=0.016). There is no significant difference between groups with and without hypnosis for the VNRS, the failure rate and the use of analgesic medication. Tubal sterilization with the Essure(®) system is a quick and efficient method. Our study does not demonstrate efficiency of hypnosis in pain control. This remains to be explored with a prospective study, including others parameters, such as anxiety. Copyright © 2011 Elsevier Masson SAS. All rights reserved.
