Atypical Centriolar Composition Correlates with Internal Fertilization in Fish.

The sperm competition theory, as proposed by Geoff Parker, predicts that sperm evolve through a cascade of changes. As an example, internal fertilization is followed by sperm morphology diversification. However, little is known about the evolution of internal sperm structures.

ERCP-related perforation: an analysis of operative outcomes in a large series over 12 years.

Background: Perforation is a rare but serious adverse event of endoscopic retrograde cholangiopancreatography (ERCP). The aim of this study was to determine the predictors of morbidity and mortality after surgical management of ERCP-related perforation (EP).

Methods: The records of patients with EP requiring surgical intervention at a tertiary referral center in a 12-year period (2004-2016) were retrospectively analyzed for demography, indications for ERCP, risk factors, timing and type of surgical repair, post-operative course, hospital stay, and outcome.

High patency of proximal splenorenal shunt: A myth or reality ? - A prospective cohort study.

Background: Proximal splenorenal shunt (PSRS) is a well-accepted surgical procedure for non-cirrhotic portal hypertension (NCPH). Though a patent shunt is important for good long term outcome, there are very few studies on patency of these shunts. We analysed shunt patency using dynamic computed tomographic (CT) portography and compared it with other modalities.

Intrarectal migration of mesh following Rectopexy: Case series and review of literature.

Introduction: Mesh rectopexy for complete rectal prolapse is associated with complications such as fecal impaction, constipation and rarely recurrence. Mesh erosion following rectopexy is rare. We report three such cases managed successfully in our unit.
