Aim Methods Results Conclusion This retrospective study aimed to assess the efficacy of prophylactic antibiotics in preventing ascending cholangitis following Kasai portoenterostomy (KPE). Data from 72 patients treated across four tertiary centres in Israel from 2008 to 2018 were analysed.Clinical and laboratory data were collected from biliary atresia (BA) diagnosis until liver transplantation (LT) or study completion.Median age at KPE was 58.5 days. Successful KPE was achieved in 23 (32%) patients. Ascending cholangitis occurred in 6/23 (26%) successful KPE cases and 15/45 (33%) unsuccessful cases. Primary antibiotic prophylaxis (49% of patients) was associated with earlier onset of cholangitis (median 77 vs 239 days, p = 0.016). During follow‐up, 39% underwent LT, with a 5‐year survival with native liver (SNL) of 54%.Prophylactic antibiotics did not reduce cholangitis rates post‐KPE in our cohort. Further research is essential to optimise management strategies for infants with BA. [ABSTRACT FROM AUTHOR]

Background: Despite accumulating data on the pathogenesis of eosinophilic esophagitis, not much is known about risk factors for the development of the disease. The role of factors such as smoking, breastfeeding, early antibiotic exposure and other factors that have been associated with other allergic diseases has not been well studied in children with eosinophilic esophagitis.Aim: To explore the role of environmental and medication exposures in the development of pediatric eosinophilic esophagitis.Methods: We conducted a cross-sectional case-control study, utilizing a parent and child questionnaire and medical chart review. Urine cotinine levels, measured by high-performance liquid chromatography, were obtained as objective evidence for smoking exposure.Results: One hundred and two children with eosinophilic esophagitis and 167 controls were recruited. The controls were mainly diagnosed with functional gastrointestinal disorders (33%) and gastroesophageal reflux disease (29%). Food allergy, specifically for peanuts and tree nuts, and allergy to pollen, tree, and grass were significantly higher among eosinophilic esophagitis children. Smoking exposure, both primary and secondary, was not associated with pediatric eosinophilic esophagitis when compared to controls (odds ratio 0.96, 95% confidence interval 0.58-1.59). Furthermore, early smoking exposure in the first year of life was higher among controls. Common accepted risk factors for allergy and atopy, such as breastfeeding practices, antibiotics exposure, animals' exposure, and others, were not found to be associated with eosinophilic esophagitis in our study.Conclusion: Common risk factors in other allergic and atopic conditions were not found to be associated with eosinophilic esophagitis.

OBJECTIVES: To characterize the clinical manifestations, outcomes, and complications of hijab pin ingestion in adolescents and to identify risk factors for a need for intervention. METHODS: A retrospective review of patients <25 years of age who presented to our emergency department because of hijab pin ingestion between 2007 and 2018. Comparison was performed between impaled and nonimpaled pins. RESULTS: We reviewed 1558 foreign-body ingestion cases. Of these, 208 (13.3%) patients presented because of hijab pin ingestion, with a total of 225 ingested pins. The mean patient age was 14.7 ± 4.1 years, and 88% of patients were girls. Time from ingestion to presentation was 24 ± 49.5 hours. Most pins were located in the stomach (46.6%), and 18.6% of all pins were impaled. Location in the stomach (odds ratio = 4.3 [95% confidence interval: 1.9-9.2]; P, .001) and abdominal tenderness on examination (odds ratio = 2.7 [95% confidence interval: 1.3-5.6]; P = .007) were strong independent risk factors for an impaled pin. Time to intervention was 22.9 hours, and 41 endoscopies were performed. One patient required laparoscopic surgery. No complications were observed. CONCLUSIONS: The hijab pin is an increasingly encountered foreign body in pediatric practice. Its specific clinical features distinguish it from other sharp objects. A delayed interventional approach in selected patients does not carry a higher risk of complications and results in significantly fewer interventions compared to existing guidelines. These findings will help guide pediatric specialists in this prevalent clinical scenario. Management recommendations are proposed. [ABSTRACT FROM AUTHOR]
