This study aimed to evaluate the correlation, according to postnatal age, between plasma B-type natriuretic peptide (BNP) levels and echocardiographic parameters for the assessment of patent ductus arteriosus (PDA) in preterm infants with respiratory distress. We enrolled 42 preterm infants with respiratory distress who underwent serial echocardiographic evaluation with simultaneous plasma BNP measurements until ductal closure. The correlations between BNP levels... |

Pompe disease is a genetic disorder caused by a deficiency of acid α-glucosidase (GAA). Infantile onset Pompe disease is uniformly lethal. Affected infants generally present in the first few months of life with hypotonia, generalized muscle weakness, and a hypertrophic cardiomyopathy, which is rapidly followed by death, usually by the age of one. The late-onset form is characterized less severe... |
Department of Pediatrics, College of Medicine, Korea University, Seoul, Korea Purpose : Vascular endothelial cell damage and alteration of a fibrinolytic system was suggested to play a role in the development of coronary artery abnormalities in Kawasaki disease (KD). D-dimer is one of the markers of endothelial damage and fibrinolysis. We evaluated the clinical usefulness of D- dimer to differentiate KD... |
We report a case in which routine chest roentgenograms of an 840 g infant led to the belief that the peripherally inserted central catheter (PICC) was appropriately positioned within the superior vena cava when, in actuality, it was within the azygous arch. Although many cases of pleural effusions have been reported to be caused by a central venous catheter, a... |
Histiocytic necrotizing lymphadenitis, which is also commonly referred to as Kikuchi's disease (KD), is a self-limiting disease of unknown etiology. It affects individuals of all ages, although it is usually seen in young women. However, only a few descriptions of this disease are available in the pediatric literature. KD is clinically characterized by cervical lymphadenopathy, high fever, myalgia, neutropenia and,... |

Purpose : Alteration in the serum level of thyroid hormone can occur following open heart surgery due to major stress and hemodilution after extracorporeal circulation but these changes have been ignored. The purpose of this study is to evaluate the changes of thyroid hormone level after open heart surgery and if these changes influence the prognosis. Methods : We evaluated 26... |
Although hypertrophic cardiomyopathy is uncommon in infant and children, we have experienced a case of dexamethasone induced hypertrophic cardiomyopathy in preterm baby who had bronchopulmonary dysplasia. This patient had hyaline membrane disease. Therefore, he received prolonged mechanical ventilation that resulted in bronchopulmonary dysplasia. After we carried out dexamethasone therapy for 7 days, hypertrophic cardiomyopathy appeared in his echocardiographic finding. We... |
Purpose : Retinoic acid(RA) is well known as a potent teratogenic agent in both deficiency and excess. Cellular retinoic acid binding proteins(CRABPs) are involved in RA. We carried this study in order to determine the possible relations of CRABPs with RA-induced teratogenesis through observation of the expression patterns of CRABP Ⅰand Ⅱ in developing rats. Methods : 35S-labeled RNA probes were... |
Purpose : Etretinate(Tigason? is an aromatic retinoid currently in therapeutic use for psoriasis but studies have shown that it is a potent teratogen in human and in experimental animal. So we carried this study to observe teratogenic effects of etretinate and to search a possibility of etretinate for using as an experimental model to induce cardiovascular malformation. Methods : In order... |
Purpose : Adrenocorticotropic Hormone(ACTH) therapy is useful in the treatment of patients with infantile spasm. However, serious side effects including Cushing syndrome, infections, hypertension, and electrolyte imbalance must be encountered. Moreover, hypertrophic cardiomyopathy in association with ACTH therapy has recently reported. We performed thiw study to evaluate the effect of ACTH on heart muscle. Methods : We administered ACTH subcutaneously to... |
Purpose : Atherosclerotic change begins in childhood, elevated blood lipid levels and a family history of premature coronary vascular diseases are important risk factors for coronary artery disease. Identification, follow-up and treatment of children at high risk of cardiovascular diseases are very effective and important for prevention of future coronary artery diseases. The purpose of this study is to determine... |
Endotheline-1(ET-1) is a potent vasoconstrictor peptide with 21 amino acid residues. ET-1 is thought to have a key role in vasoconstriction, and cardiac, renal, and endocrine actions of the peptide. Creatine Kinase(CK), also referred to as ATP-creatine-N-phosphotransferase, consists of either the B or M type. CK is found almost exclusively in muscle (MM), myocardium (MB), and brain (BB). It is... |
The clinical symptom complex characterized by syncopal attacks and sudden death in patients with electrocardiographic anomalies, especially a prolonged Q-t interval is known as the Romano-Ward syndrome. When a similar syptom complex is accompanied by congenital deafness, it is called Jervell and Lange-Nieisen syndrome. This study was underataken to investigate the incidence of the latter syndrome in the... |
Dyke-Davidoff Masson syndrome is a rare disorder which developed hemiatrophy of brain, enlargement of ventricles and prominet pneumatrization of pertous pyramid of the temporal bone. It manifests hemiparesis, varying type seizure, and mental retardation. We experienced two cases of Dyke-Davidoff-Masson Syndrome, in a 6/12 year-old boy and a 1,10/12 year-old girl who were admitted to our department of pediatrics, because of... |
Eight neonates with transient tricuspid insufficiency are presented which was confirmed clinical and two dimensional echocardiographic assessment. We found that two dimensional Doppler echocardiography was very useful in the detection of transient tricuspid insufficiency during neonatal age as noninvasive method. Transient tricuspid insufficiency is a clinical disorder in the newborn period caused by myocardial dysfunction, secondary to asphyxia with or without... |
Obesity has been implicated as a significant risk factor for multiple medical condition including hypertention, glucose intolerance, hyperlipidemia, hyperisulinemia and fatty liver. Furthermore, obesity in childhood is believed to be a reliable predictor of a similar condition in adulthood. During the recent yars, there has been a rapid rise in the incidence of childhood obesity in Korea due to increased... |

The following results were obtained. 1) Obesity index was catergorized into mild, moderate, and severe, and the percentage of mild was... |
Generally, infants of diabetic mother(IDM) have various diseases and complications affecting multisystems resulting in high perinatal morbidity and mortality. It is well known that IDM have especially higher incidence of congenital anomalies including congenital heart disease(CH D). dTransposition of great arteries(d-TGA), ventricular septal defect and hypertrophic cardiomyopathy(HCM) form most of CHD occurring in IDM. Of these, HCM appears as a... |
Prostaglandin E1 (PGE1) was administered to 12 neonates with cyanotic congenital heart disease in whom pulmonary or systemic blood flow were entirely or significantly dependent on persistent patency of the ductus arteriosus. 10 neonates responded favorably to PGE1, by showing significant increase of PaO2 after PGE1 infusion but remaining 2 neonates with hypoplastic left heart syndrome failed to respond. The... |
or vice versa. But any specific association pattern of anomalies have remained unestablished despite of many researcherss efforts. Knowledge of the likely association of CHD and extracardiac anomalies may allow us to expect certain disturbances and to correct them, and lower the mortality and morbidity rates in children with CHD. The authors conducted this study in the hope of establishing... |
Pulsed Doppler echocardiography was performed to evaluate the flow velocity pattern of the pulmonary vein in 28 patients with congenital heart diseases which comprised of 8 atrial septal defect (ASD), 14 ventricular septal defect (VSD) and 6 patent ductus arteriosus (PDA). 20 normal children served as controls. The objective of this study was to ascertain that pulmonary venous flow velocity is dependent on the... |
