BACKGROUND The sphericity of the femoral head is a metric used to evaluate hip pathologies and is associated with the development of osteoarthritis and femoral-acetabular *** To analyze the three-dimensional asphericity of the femoral head of asymptomatic pediatric *** hypothesized that femoral head asphericity will vary significantly between male and female pediatric hips and increase with age in both *** Computed tomography scans were obtained on 158 children and adolescents from a single institution in the United States(8-18 years;50%male)without hip *** femoral measurements including the femoral head diameter,femoral head volume,residual volume,asphericity index,and local diameter difference were used to evaluate femoral head *** In both sexes,the residual volume increased by age(P13 years)in females,there were no sex-differences in residual volume and aspherity *** were no age-related changes in mean diameter difference in both sexes(P=0.07)with no significant sex-differences across different age groups(P=0.06).In contrast,there were significant increases in local aspherity(maximum diameter difference)across whole surface of the femoral head and all quadrants except the inferior regions in males(P=0.03).There were no sex-differences in maximum diameter difference at any regions and age group(P>0.05).Increased alpha angle was only correlated to increased mean diameter difference across overall surface of the femoral head(P=0.024).CONCLUSION There is a substantial localized asphericity in asymptomatic hips which increases with age *** 2D measured alpha angle can capture overall asphericity of the femoral head,it may not be sensitive enough to represent regional asphericity patterns.

Background:Bilateral ovarian torsions with complete loss of ovaries is *** study analyzed the literature on bilateral ovarian torsions in girls to evaluate surgical options and ***:Literature was searched on Pubmed(R)(1987-2014) using terms 'bilateral','adnexal','ovary','torsion' and 'children'.Data were collected on age,surgical preference,pathology and ***:Thirteen articles were identified,and 9 met the inclusion criteria (5 case reports,4 original articles);and analyzed 17 girls (mean age:8.75 years,range:1-16).Bilateral oophorectomies (n=4),ipsilateral oophorectomy of severely affected ovary and contralateral oophoropexy (n=10),and detorsion of bilateral ovaries and bilateral oophoropexy (n=3) were *** torsion recurrence occurred after two *** and open surgery was done in 2 and 15 girls,*** etiology,there were simple tubo-ovarian torsions (n=8),polycystic ovary (n=1),polycystic ovary associated with Down syndrome (n=1) and corpus luteum cyst (n=1).No tumors were *** ultrasound follow-ups of ipsilateral oophorectomy and contralateral oophoropexy (n=5) confirmed follicular function (n=4) and viability and position of the ovary (n=l).Conclusions:Though extremely rare,school age girls present bilateral ovarian torsion,Ipsilateral oophorectomy and contralateral detorsion with oophoropexy has been the preferred approach.

Barrett's esophagus in children: what is the evidence?

Background This study systematically reviewed etiology, prevalence, treatment and outcome of Barrett's esophagus (BE) in the pediatric population. Methods PubMed? was searched for terms 'Barrett's esophagus' and 'children'. End points were age of patients, etiology, association with other syndromes, treatment, incidence of carcinoma and outcome. This review was conducted according to the PRISMA guidelines. Data were collected, entered and analyzed into a Microsoft Excel? spreadsheet database. Results Search revealed 278 articles published between 1984 and 2017, of which 18 met the inclusion criteria. There were 130 patients for analysis with a mean age 10.6 years (0.8–17.2 years). BE was diagnosed in 80 patients with confirmed gastroesophageal reflux (GER) only;further 20 patients were neurologically impaired and had GER, 13 after esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) repair with associated GER, 6 post-chemotherapy, 1 after post caustic burns, 1 after esophageal replacement with stomach, 1 after peptic esophageal stricture, 1 with secretory diarrhea, 1 with Fanconi anemia, 1 tetralogy of Fallot, and 5 healthy children. Regarding treatment, 26 were on medical treatment only, 16 had surgeries combined with medical treatment, 80 patients underwent surgery only, 1 was on diet management, 4 were on surveillance only and 2 were never treated for BE as death occurred because of associated conditions. Fundoplication was the most commonly performed surgery (82.2%). Adenocarcinoma was found in one 23-year-old patient. Mean follow-up was 3.45 years (10 months–13 years) and long-term outcome showed recurrences in 8 and esophago-mediastinal fistula and proximal esophagus ulcer in 1. There were 7 lethal outcomes which were not directly associated with BE. Conclusions Although BE is considered a premalignant condition;incidence of carcinoma in pediatric population is low. Long-term follow-up with endoscopies and biopsies seems to be advisable for
