Impact of percutaneous ventricular septal defect closure on left ventricular remodeling and function.

Background: Ventricular septal defect (VSD) is the most common congenital heart disease. In patients with large VSD, left side chambers are subjected to volume overload with subsequent chambers dilatation and eccentric left ventricular hypertrophy. Percutaneous closure of VSD has been shown to be an effective method with equal safety and efficacy when compared to surgery.

Correction to: Prevalence of prolonged QT interval in patients with HCV-related chronic liver disease.

Following publication of the original article [1], the authors reported that the family name of Mohamed El Kassas was incorrectly published as Mohamed ElKassas.

Prevalence of prolonged QT interval in patients with HCV-related chronic liver disease.

Background: Hepatitis C virus (HCV) is a common disease in Egypt with a high socioeconomic burden and extra-hepatic manifestations as QT prolongation, but previous studies included mainly patients with advanced liver disease, so in this study, we aimed to delineate the prevalence of QT prolongation in early-stage HCV patients.

Results: The study included 874 HCV patients with early cirrhosis; in Child's class A, 57 (6.5%) patients had prolonged QT interval corrected (QTc).

Incidence of orbital, conjunctival and lacrimal gland malignant tumors in USA from Surveillance, Epidemiology and End Results, 1973-2009.

Aim: To determine the types and incidence of tumors affecting the orbit, conjunctiva and lacrimal glands and to study the trend line of these tumors in the United States from 1973 to 2009.

Methods: We used the publicly available Surveillance, Epidemiology and End Results (SEER) database registries to determine the incidence rates. Age was adjusted to the 2000 US Standard Population.
