Clin Exp Pediatr. 2009;52(3):339-345.   Published online March 15, 2009
Purpose : This study aimed to determine the variation in parameters according to cardiac cycle length (CL; time interval between the QRS peaks on ECG) in children by using the conventional pulsed Doppler and tissue Doppler imaging echocardiography. Methods : Eighteen children with an anatomically normal heart were enrolled for the study. All children were examined by conventional and pulsed...

A Case of Korean Patient with Nonketotic Hyperglycinemia; Diagnosed Based on CSF Amino Acid Analysis and Magnetic Resonance Spectroscopy
Kie-Young Park, Ai-Rhan Kim, Ki-Soo Kim, Soo-Young Pi, Tae-Sung Ko, Jung-Hee Lee, Han-Wook Yoo

Nonketotic hyperglycinemia is an extremely rare congenital metabolic disorder, which is caused by the lack of a glycine cleavage system. The onset of hyperglycinemic symptom is during the neonatal or early infant period. Progressing grave neuromotor dysfunction is one of the main symptoms. They include myoclonic seizure, hiccup, apnea, decreased deep tendon reflex, lethargy and coma. The prognosis is mostly very poor. Furthermore, there...

Critical valvular aortic stenosis(AS) is a life threatening congenital heart anomaly in neonates or infants. The main cause of death is rapidly progressing left ventricular failure. The treatment goal of critical AS is to save left ventricular function early. Before the 1980s, the preferred treatment was surgical valvotomy, however, that operative method had a high mortality rate and risk of...
