Unusual Presentation of Pre-T Cell Acute Lymphoblastic Leukemia Massive Pericardial Effusion Only

Despite the infectious and connective tissue diseases are most encountered, etiological factors, pericardial effusions, can also rarely emerge because of malign disease in childhood and it often develops during the course of chemotherapy and radiotherapy. Unfortunately, pericardial involvement is one of the frequently encountered symptoms of pediatric malignancies. Herein, we present a rare case who was admitted with pericardial effusion and whose disease was diagnosed as pre-T cell acute lymphoblastic leukemia without peripheral blood involvement

Prolonged T-wave peak-end interval in Down syndrome patients with congenitally normal hearts

Background Heterogeneity of ventricular repolarization has been assessed using the QT dispersion in Down syndrome (DS) patients with congenitally normal hearts. Novel repolarization indexes, that is, T-wave peak-end (Tp-e) interval and Tp-e/QT ratio, however, have not previously been evaluated in these patients. The aim of this study was therefore to evaluate the Tp-e interval and Tp-e/QT ratio in DS patients without congenital heart defects

Evaluation of ventricular arrhythmogenesis in children with acute rheumatic carditis

Background: Recent studies have shown that the Tp-e interval, which on an electrocardiogram (ECG) is the interval between. the peak and the end of the T wave, can he used as an index of transmural dispersion of ventricular repolarisation (UDR). Both Tp-e/QT and Tp-e/QTc ratios have also been used in that capacity. However, these novel repolarisation indices have not previously been studied in children with acute rheumatic carditis (ARC)
