Esophageal replacement in children - 27 years of experience in a University Hospital.

Introduction: esophageal replacement in children is indicated when it is impossible to maintain the native esophagus, which in the pediatric population includes patients with esophageal atresia and esophageal caustic stenosis. The objective of this communication is to report the experience of a university service with two techniques of esophageal replacement.

Methods: this is a retrospective study based on the revision of hospital files.

Analysis of the efficacy and safety of conservative treatment of blunt abdominal trauma in children: retrospective study. Conservative treatment of blunt abdominal trauma in children.

Introduction: in Brazil, trauma is responsible for 40% of deaths in the age group between 5 and 9 years old, and 18% between 1 and 4 years, and bleeding is the leading cause of preventable death in the traumatized child. Conservative management of blunt abdominal trauma with solid organs injury - started in the 60s - is the current world trend, with studies showing survival rates above 90%. The objective was to assess the efficacy and safety of conservative treatment in children with blunt abdominal trauma treated at the Clinical Hospital of the University of Campinas, in the last five years.

BISHOP-KOOP OSTOMY REVISITED: A "TEST-DRIVE" INTESTINAL DIVERSION FOR CHILDREN WITH SUSPECTED BOWEL DYSMOTILITY.

Background: Bishop-Koop ileostomy has been widely used in pediatric patients with the intention of including as much bowel as possible in the intestinal transit early in the management of children with meconium ileus and intestinal atresia. In recent years, we have been using it as an alternative to test the distal bowel function before closure of a previously constructed ostomy in selected children with questionable distal bowel motility.

Aims: The aim of this study was to present our experience with this alternative use of the Bishop-Koop ostomy.

Analysis of anti-Müllerian hormone (AMH) and its receptor (AMHR2) genes in patients with persistent Müllerian duct syndrome.

Objective: To screen for mutations in AMH and AMHR2 genes in patients with persistent Müllerian duct syndrome (PMDS).

Patients And Method: Genomic DNA of eight patients with PMDS was obtained from peripheral blood leukocytes. Directed sequencing of the coding regions and the exon-intron boundaries of AMH and AMHR2 were performed.
