Background: Survival of newborns with gastroschisis is significantly higher in high-income versus low and middle-income countries. We reviewed treatment and outcomes of gastroschisis in a middle-income country setting with increasing protocolized management.
Methods: All newborns with gastroschisis treated during the period 1989-2013 at a single Brazilian academic surgical service were studied retrospectively.
Objective: to determine, in pediatric patients with malignant neoplasms, the characteristics of pulmonary nodules identified on computed tomography, as well as the possibility of differentiating benign lesions from metastases.
Methods: we conducted a retrospective study of patients submitted to pulmonary resections of nodules diagnosed as metastases in a period of seven years. We compared computed tomography and surgery findings, as well as results of anatomopathological examinations.
Purpose: To compare the measurement of the testicular volume of Wistar rats using a caliper and ultrasonography.
Methods: Forty Wistar rats were randomly assigned into four groups. A tensile force of 1.
Background: Bladder perforation by ventriculoperitoneal shunt is a rare complication that has been describe in 19 cases in prior literature.
Case Description: This work describes the case of a 4-month-old baby who presented with extrusion of the distal catheter through the urethra. The patient underwent a laparotomy; the catheter was cut close to the bladder wall and repositioned into the peritoneal cavity.
Purpose: To determine whether tension in the spermatic cord of rats causes lesions in the testis, epididymis or vas deferens.
Methods: Forty Wistar rats were randomly allocated into four groups. A traction force of 1.
Purpose: To investigate the effects of human chorionic gonadotropin (hCG) on the testicular tissue of young male rats.
Methods: Male Wistar rats were assigned to groups (10 rats/group).Control Group received subcutaneous saline solution; Group 1 received hCG 50 UI/Kg/dose; and Group 2 received hCG 100 UI/Kg/dose, daily for 15 days.
Purpose: To evaluate the effect of decompression fasciotomy on testes undergoing torsion of the spermatic cord.
Methods: Spermatic cord torsion was induced in 40 Wistar testes for six and 12 hours. At the time of distortion, decompression fasciotomy was performed on half of the animals.
We report a case of a nine-year-old boy with a 4-week history of general fatigue, loss of appetite, vomits and hematemesis. Laboratory evaluation revealed a hemoglobin level of 4.4 g/dl.

The aim of this study was to review 10 children with 46,XX CAH who underwent one-stage total urogenital sinus mobilization (TUM). Age at operation ranged from 11 to 78 months (mean= 32) and the follow-up from 15 to 36 months (mean= 26).

Methods: Fifty-three children with unilateral multicystic dysplastic kidney detected by prenatal ultrasound between 1989 and 2004 were included in the analysis. All children were submitted to conservative management with follow-up visits every six months.
