Assessing Patent Ductus Arteriosus (PDA) Significance on Cardiac Output by Whole-Body Bio-impedance.

We evaluated the effectiveness of a whole-body bioimpedance device (NICaS®, NI Medical, Petach Tikva, Israel) to predict the presence of a hemodynamically significant patent ductus arteriosus (PDA) in premature infants. A total of 36 infants less than 35 week's gestation age and birth weights of less than 1750 g were included in the study. Using the NICaS® device, we obtained whole-body bioimpedance measurements of stroke volume index (SI), cardiac output index (CI) and total peripheral resistance index.

Late cardiac assessment in children diagnosed with post-streptococcal reactive arthritis: a long term study.

Objectives: Unlike rheumatic fever (RF), the association of post-streptococcal reactive arthritis (PSRA) and carditis is controversial. The American Heart Association recommends anti-streptococcal prophylaxis for PSRA for one year, repeating echocardiogram and discontinuation of prophylaxis if normal. In this study the possibility of late cardiac involvement was investigated in a cohort of children with PSRA.

An unusual neonatal presentation of anomalous origin of the left coronary artery arising from the pulmonary artery.

We describe a previously unreported neonatal presentation of an anomalous origin of the left coronary artery arising from the pulmonary artery. This is a full-term female infant after normal pregnancy and delivery. The baby was diagnosed at 2 days of age due to weak femoral pulses noted on the routine nursery discharge examination.

Transcatheter closure of pulmonary arteriovenous malformations with amplatzer devices.

Objective: To review the authors' experience with transcatheter closure of pulmonary arteriovenous malformations (PAVMs) using amplatzer duct occluder (ADO) devices and vascular plugs (AGA Medical, Golden Valley, MN) and present a novel technique for delivery sheath placement and device delivery.

Background: PAVMs can cause cyanosis, fatigue, polycythemia, and thromboembolic phenomena. Transcatheter closure using coils, detachable balloons, and various devices has replaced surgery as the preferred therapy.

Corticosteroid treatment in patients with Sydenham's chorea.

Sydenham's chorea occurs in approximately 10% of acute rheumatic fever and is one of its major manifestations. The disease may last for weeks or months, with a high risk of recurrence; usually only supportive treatment is recommended. This report describes five children diagnosed with Sydenham's chorea and treated with a short course of corticosteroids.
