Reports state that Down syndrome (DS) patients with congenitally normal hearts might experience the development of cardiac abnormalities such as cardiac autonomic dysfunction, valvular lesions, bradycardia, and atrioventricular block. However, the presence of any difference in terms of P-wave dispersion (PWd) and QT dispersion (QTd) was not evaluated(More)
Oriental beech (Fagus orientalis Lipsky.) and Oriental spruce [Picea orientalis (L.) Link] are the two most common tree species in northeast Turkey. Their distribution, stand type and understorey species are known to be influenced by topographical landforms. However, little information is available as to how these changes affect litter decomposition rates(More)
Background The association between ketogenic diet (KD) and prolonged QT interval, life-threatening ventricular arrhythmias, and sudden death is controversial. Aim We aimed to prospectively evaluate the effect of KD on electrocardiography (ECG) measures in children with refractory epilepsy. Method A total of 70 children with drug-resistant epilepsy who(More)
The closure of a secundum atrial septal defect through the jugular vein in a child with interrupted inferior vena cava with azygos continuation by steerable delivery catheter is described in the present report. The steerable catheter can be used to correct the perpendicular position of the device over the margins of the defect, and is particularly useful in(More)
BACKGROUND The Modified Blalock-Taussig shunt procedure can provide increased flow of blood to the lungs for babies born with certain congenital heart defects. We evaluated 44 subjects under 2 years of age who had a Modified Blalock-Taussig shunt (MBTS) procedure performed from 2009-2013, to investigate risk factors for thrombosis, overshunting and death.(More)
Hemolysis after percutaneous device closure of ventricular septal defect (VSD) is a rare complication that can be conservatively managed in the majority of cases. However, surgery or transcatheter occlusion may be necessary. Presently described is the successful treatment of hemolysis that developed after implantation of the Nit-Occlud Lê VSD coil, using(More)
AIM We analysed 25 children with 21-hydroxylase deficiency who received glucocorticoid and/or mineralocorticoid treatment for at least 12 months to determine the effects of the disease and its treatment on vascular structures and ventricular function. METHODS Twenty-five patients with 21-hydroxylase-deficient congenital adrenal hyperplasia (CAH) and 25(More)
OBJECTIVE Rheumatic heart disease is still a major health problem in developing countries. The impact of coronary artery disease (CAD) on or its relation to rheumatic fever is not well established. We aimed to evaluate the prevalence of CAD and atherosclerotic risk factors in patients who underwent valvular surgery due to rheumatic heart disease. METHODS(More)
Heterotaxy syndrome is a rare complex syndrome characterized by cardiac and extra cardiac congenital malformations. The syndrome is divided into two main groups; right isomerism (Ivemark syndrome, asplenia) and left isomerism (polysplenia syndrome). Here we report a polysplenia syndrome with agenesis of head and uncinate process of the pancreas in a 52 year(More)
Stent restenosis remains the main limitation of percutaneous coronary intervention. Elevated serum gamma-glutamyl transferase (GGT) level is associated with an inflammatory response. We aimed to determine the correlation of stent restenosis with the serums level of GGT. One hundred and twenty patients (age 58.56+/-10.46 years, 66% male) with a history of(More)
