Penetrance of the R337H Mutation and Pediatric Adrenocortical Carcinoma Incidence Associated with Environmental Influences in a 12-Year Observational Cohort in Southern Brazil.

The R337H mutation is associated with increased incidence of pediatric adrenocortical tumor (ACT). The different environmental conditions where R337H carriers live have not been systematically analyzed. Here, the R337H frequencies, ACT incidences, and R337H penetrance for ACT were calculated using the 2006 cohort with 4165 R337H carriers living in Paraná state (PR) subregions.

Simulation in Pediatric Video Surgery: Training with Simple and Reproducible Exercises Elaborated by Residents.

Most residents do not have a defined program for simulation training in video surgery in Brazil. The training takes place for the most part or in short courses. The goal of this article is to describe and evaluate a set of exercises using low-cost materials, created by the residents themselves, to enable basic skills training in video surgery.

Choledochal cyst in the pediatric population: experience of 13 laparoscopic procedures in two years at a single institution.

Objective: to describe the first 13 cases of laparoscopic correction of common bile duct cyst in the Pequeno Príncipe Hospital, Curitiba, Paraná, Brazil.

Methods: we performed a retrospective analysis of medical records of cases of choledochal cyst operated by laparoscopy between March 2014 and September 2016.

Results: of the 13 patients, eight were female and the mean age at surgery was 7.

Impact of neonatal screening and surveillance for the TP53 R337H mutation on early detection of childhood adrenocortical tumors.

Purpose: The incidence of pediatric adrenocortical tumors (ACTs) is remarkably high in southern Brazil, where more than 90% of patients carry the germline TP53 mutation R337H. We assessed the impact of early detection of this mutation and of surveillance of carriers.

Patients And Methods: Free newborn screening was offered at all hospitals in the state of Paraná.
