Metabolic syndrome in Turkish children and adolescents.

The aim of this study was to determine the prevalence and phenotype of metabolic syndrome in Turkish children and adolescents. We adapted the National Cholesterol Education Program Adult Treatment Panel III criteria of metabolic syndrome to children and adolescents. Using the international cutoff points and percentiles, we determined 10- to 17-year-old Turkish children and adolescents with high blood pressure, high triglyceride (TG), low high-density lipoprotein cholesterol (HDL-C), fasting glucose of 100 mg/dL or greater, and elevated body mass index corresponding to overweight or obesity.

Active-fixation, steroid-eluting ventricular leads: the medium-term results in children.

Objective: Low threshold characteristics and mechanical stability are important features of an ideal pacing lead, especially for children. We report our experience and medium-term results with a steroid-eluting, active-fixation ventricular lead in children.

Methods: Telectronics Accufix II DEC model 033-212 ventricular leads were implanted in 21 patients.

Body mass index and lipid levels in children from Ankara, Turkey versus Bogalusa, Louisiana.

Background: Turkish Heart Study demonstrated that low high density lipoprotein cholesterol levels are prevalent among Turkish adults.

Methods: We compared body mass index and lipid levels of Turkish children (n = 1525, ages 10-17) with the bi-racial community of Bogalusa Heart Study.

Results: Turkish children have lower body mass index than American children (19.

Spontaneous resolution of ventricular tachycardia with right bundle branch block morphology: a case report.

Ventricular tachycardia is rare in children. In the absence of structural heart disease, ventricular tachycardia is known as idiopathic ventricular tachycardia and carries a good prognosis. We report a 14-month-old male child with right bundle branch block incessant ventricular tachycardia without structural heart disease.

Reproducibility of the head-up tilt test results in children with vasovagal syncope.

Background: This prospective study aims to investigate the reproducibility of HUTT results in children with typical history of vasovagal syncope.

Methods: Between October 1996 and October 1999, 58 children with a history of typical vasovagal syncope attacks were evaluated with head up tilt test (HUTT). The table was tilted to 60 degrees and the patients were monitored for heart rate and blood pressure changes during 45 min.

Assessment of left ventricular systolic and diastolic functions in children with merosin-positive congenital muscular dystrophy.

Cardiopathy is an expected finding in X-linked Duchenne and Becker muscular dystrophies. This holds true for some other forms such as autosomal recessive limb-girdle dystrophies. However, data on early-onset and usually severe congenital muscular dystrophies are limited.

Sinus node dysfunction in children and adolescents: treatment by implantation of a permanent pacemaker in 26 patients.

Sinus node dysfunction has been reported rarely in pediatric patients with structurally normal hearts. It has been diagnosed with increasing frequency in children and young adult patients with congenital heart defect, especially in patients who have undergone corrective cardiac surgery related with atrial tissue. Between 1984-1999, 26 patients who were under 22 years of age underwent implantation of a permanent pacemaker for treatment of sinus node dysfunction at our medical center.

Dual chamber cardiac pacing in children: Single chamber pacing dual chamber sensing cardiac pacemaker or dual chamber pacing and sensing cardiac pacemaker?

Background: Dual chamber pacemakers (single chamber pacing dual chamber sensing cardiac pacemaker (VDD) and dual chamber pacing and sensing cardiac pacemaker (DDD)) are being used frequently in children and adolescents. The aim of this study was to verify the safety and performance of the VDD and DDD pacing systems, and to evaluate the differences between two pacing modes with regard to atrial sensing and tracking functions.

Methods: In this study, we evaluated 14 patients with VDD pacing and 15 patients with DDD pacing between 1994 and 2000.

Incidence of dysrhythmias in congenitally corrected transposition of the great arteries.

We reviewed hospital records of 45 children with corrected transposition of the great arteries (c-TGA) to determine the incidence and outcome of congenital and postoperative dysrhythmias seen in this congenital anomaly. Our study comprised 45 patients (12 girls, 33 boys). The mean age of the patients at initial evaluation was 3.

Influence of D-net (EUROPEAN GSM-standard) cellular telephones on implanted pacemakers in children.

This study was designed to evaluate possible interactions between digital cellular telephones and implanted pacemakers in children. The study comprised 95 patients (53 males and 42 females) with a mean age of 11.5 +/- 4.

Dysrhythmia as a cause of syncope in children without neurological or cardiac morphological abnormalities.

Background: Arrhythmias are among the malignant causes of syncope. This study has been undertaken to determine the relative incidence and significance of dysrhythmia in the pathogenesis of syncope among patients referred to a pediatric cardiology unit.

Methods: Between March 1997 and March 1999, 105 consecutive patients (59 female, 46 male) aged 11.

Complications and outcome in left-sided endocarditis in children.

We retrospectively assessed the clinical course and outcome of left-sided endocarditis in pediatric patients to find out the prognostic significance of the presence and size of echocardiographically detected vegetations. Among the children admitted to our institution with endocarditis between January 1987 and October 1999, 16 patients (mean age 9.03 +/- 4.
