Evaluation of diastolic dysfunction in children with hypertrophic cardiomyopathy and its relationship with development of myocardial fibrosis.

Background: Patients with hypertrophic cardiomyopathy may develop symptoms of shortness of breathing due to diastolic dysfunction which is not related to the severity of left ventricular outflow tract obstruction. As these patients usually develop a non-ischemic pattern of myocardial fibrosis, this may represent a mechanism for increased myocardial stiffness leading to impaired diastolic filling. The study aimed to determine the prevalence of myocardial fibrosis assessed by magnetic resonance imaging in children with hypertrophic cardiomyopathy and to evaluate its relationship with echocardiographic parameters including left ventricle diastolic dysfunction and to find echocardiographic indices which correlates with myocardial fibrosis as detected by cardiac magnetic resonance.

Repolarization Patterns in Congenital Heart Disease.

The aim of this study was to study the repolarization patterns in pediatric patients with cyanotic and acyanotic congenital heart diseases as prolonged QT indicates a myocardium at risk of ventricular arrhythmia. A cross-sectional case-control study included 50 patients with acyanotic congenital heart diseases and 50 patients with cyanotic congenital heart diseases who presented to Catheterization Unit of Cairo University Pediatric Hospital between March 2013 and June 2014. We included 50 healthy children as a control.

INTESTINAL PARASITIC INFECTIONS AND ATOPIC DISEASES IN CHILDREN: A HOSPITAL BASED STUDY.

Different helminth parasites may have different effects on allergy depending on the timing of the exposure. A meta-analysis of many of studies reported the association between the presence of geohelminth eggs in stool samples and asthma provided some evidence for parasite-specific effects. This study evaluated the occurrence of allergy among different intestinal parasitic infected patients.
