Percutaneous core needle biopsy of neuroblastoma in the pediatric population: what have we learned in the last decade.

Introduction: Historically, neuroblastoma has been diagnosed by surgical open biopsy (SB). In recent decades, core needle biopsy (CNB) has replaced surgical biopsy due to its safe and adequate method of obtaining tissue diagnosis.

Aim: Our study aimed to assess the effectiveness of CNB in obtaining tissue diagnosis for neuroblastoma and evaluate its safety profile in terms of post-operative complications, in comparison to SB.

Clinical Presentation of Patients with Eosinophilic Gastrointestinal Diseases beyond Eosinophilic Esophagitis.

The clinical presentation of eosinophilic gastrointestinal diseases beyond eosinophilic esophagitis (non-EoE EGIDs) varies depending on the gastrointestinal segments affected by the eosinophilic inflammation, the extent of eosinophilic inflammation within the gastrointestinal tract and its depth through the bowel wall. Non-EoE EGIDs with mucosal involvement tend to present with diarrhea, malabsorption, and sometimes bleeding, those with muscular involvement may present with symptoms of obstruction or pseudo-obstruction, intussusception, and even perforation, whereas those with serosal involvement may present with eosinophilic ascites. Here we describe the differences in symptoms experienced by children with non-EoE EGIDs with varying degrees of eosinophilic inflammation through the bowel wall.

An "On Demand" canakinumab regimen for treating children with Colchicine-Resistant familial Mediterranean fever - A multicentre study.

Objectives: Canakinumab, a human monoclonal antibody targeted at interleukin-1 beta, has demonstrated safety and efficacy in preventing familial Mediterranean fever (FMF) attacks among individuals with colchicine-resistant (crFMF). The manufacturer orders prescribe monthly subcutaneous injections. However, a subset of our patients is treated with an "canakinumab on demand " (COD) strategy, with wider intervals between drug administrations.

Recurrence rates of pilonidal sinus disease in the pediatric population following trephine surgery.

Background: Pilonidal sinus disease (PSD) is a common surgical disease. Multiple surgical methods exist in the literature, without clear consensus regarding which should be the first-line treatment. Minimally invasive methods such as the Gips procedure are gaining popularity in recent years.

Barriers to Adolescents' Adherence to Medical Advice after Metabolic Bariatric Surgery: A Statistical Analysis.

Adolescent obesity has markedly increased worldwide, and metabolic bariatric surgery is an effective treatment option. A major predictor of the outcomes of this procedure is adherence to post-surgery lifestyle changes and medical recommendations. While adolescents generally have more difficulty adhering to medical advice than adults, their failure to do so could adversely affect their physical and psychological health, the cost-effectiveness of medical care, and the results of clinical trials.

Pathogens Causing Pediatric Community Acquired Urinary Tract Infections and Their Increasing Antimicrobial Resistance: A Nationwide Study.

Urinary tract infections (UTIs) in childhood are common and are associated with considerable acute morbidity and long-term complications. The need for updated data to optimize empiric antibiotic therapy is crucial. We aimed to investigate the pathogens causing pediatric community acquired UTIs, their correlation with demographic characteristics, and trends in their antimicrobial resistance.

Autoimmune encephalitis in Israeli children - A retrospective nationwide study.

Immune-mediated or autoimmune encephalitis (AE) is a relatively new, rare and elusive form of encephalitis in children. We retrospectively collected seropositive children (0-18 years old) with well characterized antibodies through 3 reference laboratories in Israel. Clinical symptoms, MRI and EEG findings and treatment courses were described.

Children with idiopathic short stature have significantly different gut microbiota than their normal height siblings: a case-control study.

Objectives: To investigate the role of gut microbiota (GM) in pathogenesis of idiopathic short stature (ISS) by comparing GM of ISS children to their normal-height siblings.

Methods: This case-control study, conducted at the Schneider Children's Medical Center's Institute for Endocrinology and Diabetes between 4/2018-11/2020, involved 30 pairs of healthy pre-pubertal siblings aged 3-10 years, each comprising one sibling with ISS and one with normal height. Outcome measures from fecal analysis of both siblings included GM composition analyzed by 16S rRNA sequencing, fecal metabolomics, and monitoring the growth of germ-free (GF) mice after fecal transplantation.

Editorial: From the Identified Patient to Precision Medicine.

The article by Lock et al. in this month's issue of the Journal highlights 3 features that are of interest to child and adolescent psychiatrists. First, it provides further evidence for an effective therapy for an extremely debilitating condition, with additional means for improving prognosis.

Delayed Rewarming Thrombocytopenia: A Suggested Preventable and Treatable Cause of Rewarming Deaths.

The lack of a consensus of accepted prognostic factors in hypothermia suggests an additional factor has been overlooked. Delayed rewarming thrombocytopenia (DRT) is a novel candidate for such a role. At body temperature, platelets undergoing a first stage of aggregation are capable of progression to a second irreversible stage of aggregation.
