Insights into enlarged prostatic utricles and Müllerian duct system remnants associated with posterior hypospadias.

Introduction: The prostatic utricle (PU) consists of the caudal remnant of the Müllerian duct and the urogenital sinus. The term "vagina masculina" is used if other Müllerian structures are associated with the PU. This work aims to investigate the incidence, management, and follow up of enlarged PUs and Müllerian remnants in males with posterior hypospadias.

Iris recognition approach for identity verification with DWT and multiclass SVM.

The iris has been proven to be one of the most stable and accurate biometrics. It has been widely used in recognition systems to determine the identity of the individual who attempts to access secured or restricted areas (., airports, ATM, datacenters).

Vesico-cutaneous fistula: A modified technique for intermittent catheterization in children with impaired bladder function.

Background: Clean intermittent catheterization (CIC) is fundamental in managing children with impaired bladder function. However, it is not always feasible via the native urethra predominately males with intact sensation.

Aim: In the current study, the experience regarding a modified vesico-cutaneous fistula (VCF) technique for CIC in children is reported.

Closed Gastroschisis.

Closed gastroschisis is a rare entity usually associated with intestinal atresia and short bowel syndrome. We report two cases of closed gastroschisis presenting with neonatal intestinal obstruction and para-umbilical evisceration without an abdominal defect.

Colonic Atresia: Association with Other Anomalies.

Background: Colonic atresia (CA) is a rare form of congenital intestinal atresia. Although CA may be isolated, it is more commonly reported in literature in association with other congenital anomalies.

Materials And Methods: This study is a review of prospectively collected data of all the patients with colonic atresia presented to our center (Ain Shams University) during 2008 to 2016.

Surgical aspects of inflammatory bowel diseases in pediatric and adolescent age groups.

Background: Inflammatory bowel disease (IBD) is increasingly encountered in children. Early disease is associated with higher complication rate with increased incidence of surgical intervention.

Patients And Methods: From January 2010 to June 2015, 25 patients in the pediatric and adolescent age groups with IBD underwent surgical intervention in our center.

Low pH induces co-ordinate regulation of gene expression in oesophageal cells.

The development of gastro-oesophageal reflux disease (GORD) is known to be a causative risk factor in the evolution of adenocarcinoma of the oesophagus. The major component of this reflux is gastric acid. However, the impact of low pH on gene expression has not been extensively studied in oesophageal cells.
