Evaluation of the relationship between mast cell activation and postural orthostatic tachycardia syndrome in children and adolescents.

Objective: Postural orthostatic tachycardia syndrome (POTS) is one of the orthostatic intolerance syndromes that are common in young adolescents and impair quality of life. POTS is a multi-systemic disease. Many mechanisms have been defined in POTS etiology, such as autonomic denervation, hypovolemia, hyperadrenergic stimulation, low condition, and hypervigilance.

Retrospective evaluation of 130 cases with kawasaki disease follow-up in a tertiary care center in Turkey between 1999 and 2019: a 20-year experience.

Objectives: Kawasaki disease (KD), which is a medium vessel vasculitis, is common in Asian countries and is the most common cause of childhood-acquired heart diseases in developed countries. However, disease course and epidemiological data are limited in non-Asian developing countries like ours. We aimed to evaluate the clinical features and prognosis of patients with KD in our country and ethnicity, one of the referee centers of our country.

Evaluation of clinical features and outcome of eight fetuses with ectopia cordis; A study from a fetal cardiology center.

We aim to evaluate the clinical course and outcome of cases with a prenatal diagnosis of ectopia cordis in our center. In this retrospective study, we analyzed clinical variables including gestational age at diagnosis, maternal age, associated cardiac, extracardiac, genetic anomalies and, outcome in prenatally diagnosed ectopia cordis cases in our tertiary referral center. Eight ectopia cordis cases from seven pregnancies were included in the study.

Is there myocardial involvement in children with long-term follow-up for Kawasaki disease? A study based on two-dimensional speckle tracking echocardiography.

Objective: This study aimed to determine the possibility of subclinical myocardial dysfunction detected by strain echocardiography in the late period of children with Kawasaki disease.

Material And Methods: The study enrolled 30 patients with Kawasaki disease with a follow-up period of at least 12 months and 30 healthy age- and gender-matched children. During the follow-up period, standard echocardiography, pulsed and tissue Doppler, and strain echocardiography were recorded for both groups.

Effect of high-dose oral cholecalciferol on cardiac mechanics in children with chronic kidney disease.

Cardiovascular factors are an important cause of mortality in chronic kidney disease, and vitamin-D deficiency is common in this patient population. Therefore, we aimed to investigate the effect of oral cholecalciferol on cardiac mechanics in children with chronic kidney disease. A total of 41 children with chronic kidney disease - the patient group - and 24 healthy subjects - the control group - free of any underlying cardiac or renal disease with low 25-hydroxyvitamin-D3 levels were evaluated by conventional tissue Doppler imaging and two-dimensional speckle-tracking echocardiography, both at baseline and following Stoss vitamin-D supplementation.

A rare cause of early repolarisation in an adolescent boy with chest pain: myocardial bridging.

Early repolarisation is a common electrocardiographic (ECG) finding characterised by J-point and ST segment elevation ≥ 0.1 mV in two or more adjacent leads. The ECG pattern of early repolarisation is relatively common in asymptomatic subjects.

Left ventricular mechanics are affected in children with celiac disease: A study based on two-dimensional speckle tracking echocardiography.

Background: An association between cardiomyopathy and celiac disease has been reported, but not frequently. We examined the effects on cardiac mechanics in children with celiac disease (CD) by two-dimensional speckle tracking echocardiography (2DSTE).

Methods: Eighty-one children with CD were compared with a control group comprising 51 healthy children by echocardiographic examination.

Effect of cholecalciferol on local arterial stiffness and endothelial dysfunction in children with chronic kidney disease.

Background: As cardiovascular factors are the leading cause of mortality in chronic kidney disease (CKD) and as vitamin D deficiency is prevalent in this population, we aimed to examine the effect of oral cholecalciferol on cardiac parameters and biomarkers for endothelial cell activation in children with CKD.

Methods: Forty-one children with CKD and 24 healthy subjects free of any underlying cardiac or renal disease with low 25-hydroxyvitamin D3 (25OHD) levels were evaluated using echocardiography basally and following Stoss vitamin D supplementation. The local vascular stiffness and endothelial dysfunction markers were compared among the groups.

Prevalence of overweight and obesity among patients with congenital and acquired heart disease in Kocaeli, Turkey.

Background: Childhood obesity has increased in the last half of the century. The aim of this study was to evaluate the frequency of obesity in the children with congenital or acquired heart disease.

Methods: A total of 1410 children were assessed in this study.

Effects that different types of sports have on the hearts of children and adolescents and the value of two-dimensional strain-strain-rate echocardiography.

Whether the hypertrophy found in the hearts of athletes is physiologic or a risk factor for the progression of pathologic hypertrophy remains controversial. The diastolic and systolic functions of athletes with left ventricular (LV) hypertrophy usually are normal when measured by conventional methods. More precise assessment of global and regional myocardial function may be possible using a newly developed two-dimensional (2D) strain echocardiographic method.

Crossed pulmonary arteries: a report on 20 cases with an emphasis on the clinical features and the genetic and cardiac abnormalities.

Crossed pulmonary arteries (CPAs) are a rare abnormality in which the ostium of the left pulmonary artery originates superior to the right pulmonary artery and to its right. Recognition of this rare pathology is important because it generally is accompanied by other congenital heart defects, extracardiac anomalies, and certain genetic problems. To date, only a few cases have been reported, and most of these cases have been associated with complex cardiac abnormalities.
