Purpose : Chromosome microdissection has become a very powerful approach to generate chromosome band-specific library and painting probes for physical mapping or cytogenetic analysis. We have constructed here band-specific painting probes for human chromosomes by microdissection and polymerase chain reaction(PCR). Methods : We pretreated the microdissected fragments with Topoisomerase I(Topo I) which catalyzes the relaxation of supercoiled DNA, and performed... |
Purpose : Cisapride, a prokinetic agent, is widely used in preterm infants with feeding intolerance or gastroesophageal reflux. Although cisapride is regarded as a safe drug, increased QTc interval or ventricular arrhythmia has been reported in adults and neonates. So we prospectively examined the effects of cisapride on the QTc interval and QT dispersion in preterm infants. Methods : QTc interval... |
Purpose : Adenoviral respiratory infection can develop a life threatening condition similar to severe bacterial pneumonia. Despite adequate intensive care, this infection progresses to acute respiratory distress syndrome and causes permanent lung damage in some patients. In this study, we analyzed clinical features and long-term follow-up clinical data of this infection in children. Methods : Forty-seven cases of inpatients were diagnosed... |
Purpose : To find out the efficacy, safety and early complication of radiofrequency catheter ablation(RFCA) in pediatric patients with paroxysmal tachycardia, we compared short-term results of RFCA in pediatric patients to adult patients. Methods : We studied 25 patients(11 pediatric patients, 14 adult patients), who underwent RFCA due to paroxysmal supraventricular tachycardia(PSVT) or idiopathic ventricular tachycardia(VT) from November 1997 to August... |
Purpose : RFCA has been proven to be an effective and safe tool for treating different kinds of tachycardia in adults. This study was designed to analyze the efficacy of this method in children and adolescents.

Purpose : Abnormality in the composition of lipid metabolism is well known to be a main cause of atherosclerosis. Accordingly the abnormality in lipid metabolism after suffering from Kawasaki disease may lead to premature coronary atherosclerosis. The aim of this study is to investigate the abnormalities of lipid metabolism in patients with Kawasaki disease. We studied 67 patients with Kawasaki... |
Purpose : Intravenous gamma globulin(IVGG) treatment has reduced symptoms and complications in Kawasaki disease(KD). However, fever persisted in 20-30% of the patients, and there are no reliable data on the indication and dosage of IVGG re-treatment. Therefore, we tried to reveal the effectiveness of IVGG re-treatment and to find risk factors in predicting the re-treatment. Methods : Among 57 patients with... |
Purpose : Total anomalous pulmonary venous return is a rare congenital heart disease, which is fatal if untreated, especially, if the obstruction in pulmonary venous return is obstructed. With the technical development of echocardiogram, we are now able to do an early diagnosis if TAPVR and perform surgery. Accordingly, this report was aimed to evaluate patients with TAPVR as well... |
Purpose : Systemic lupus erythematosus(SLE) is a disease of immunologic origin, affecting multiple organs including joints, skin, kidneys, nervous system, heart and blood, with rare involvement of gut and liver. The incidence of renal disease in children with SLE was approximately 70 percent and tended to be more severe than in adults. Accordingly we have retrospectively studied on the prognostic... |
Purpose : Cryopreserved stem cells from cord blood are usually infused with Dimethyl Sulfoxide (DMSO) immediately after thawing. However, this process may cause cell damage due to osmotic shock, and the administration of DMSO may also cause toxic effects. We studied a new method of increasing cell viability by stabilizing osmolarity by adding dextran 40 and washing out DMSO. Methods :... |
Purpose : Growth hormone(GH) is a powerful inhibitor of lipoprotein lipase and is known to decrease fat cell mass. The lipolytic effect has more pronounced influence on visceral fat than subcutaneous fat. The effects of GH therapy on GH receptor in fat tissue are not clear. We investigated the changes in fat tissue and GH receptor mRNA in adipose tissue... |
Purpose : Persistent hyperinsulinemic hypoglycemia of infancy(PHHI), which is characterised by inappropriate insulin secretion in spite of hypoglycemia, needs urgent treatment to prevent cerebral hypoglycemic damage. Although pancreatectomy is the treatment of choice for PHHI, there are several complications which follow treatment. We suggest that aggressive medical therapy, when effective, is preferable to partial pancreatectomy. Methods : We evaluated 8 patients... |
Purpose : Although Henoch-Schönlein purpura(HSP) has been described in detail, there is a paucity of information describing scrotal involvement and risk factors for renal involvement. This study was performed to evaluate the incidence of scrotal involvement and the relationship between renal and nonrenal involvement, including scrotal involvement. Methods : We retrospectively reviewed medical records of 164 male children who were diagnosed... |
Purpose : Seizures during the neonatal period may be an important indicator of serious neurologic abnormalities and can cause permanent neurologic sequelae. We attempted to find and analyze the factors related to the outcome of neonatal seizures. Methods : Seventy-six newborns with seizure were reviewed. The outcomes were analyzed according to etiologic diseases, gestational ages, characteristics of seizure, and neuroimaging and... |
Since Pallister first described 12p tetrasomy syndrome in 1977, approximately 50 patients have been described. Chromosomal study of lymphocyte is normal in most cases, but fibroblasts usually reveal 12p tetrasomy in chromosomal study. We report on a 17-month-old male infant with Pallister-Killian syndrome. He was admitted in our hospital for investigation of developmental delay and myoclonic seizure. He was diagnosed... |
Megacystis Microcolon Intestinal Hypoperistalsis(MMIH) Syndrome is a rare cause of functional neonatal bowel obstruction, characterized by hypoperistalsis, narrow distal ileum and colon, and bladder distension. We report a case of MMIH syndrome and review the literature. The patient was born after 34 weeks of gestation with marked abdominal distension. Her birth weight was 2,830g with 276ml of urine drained by... |
Intrahepatic portosystemic venous shunt(IPVS) is an uncommon pathologic condition which occurs mostly in adult patients with portal hypertension and cirrhosis of the liver with only scattered reports are on children. However, asymptomatic IPVS have been detected in an increasing number of patients with recent advances in imaging techniques, such as sonography, CT, MR imaging, and color Doppler sonography. The cause... |
Hepatoblastoma is the most common primary malignant liver tumor in childhood. Most cases are boys generally below three years of age. Hepatoblastoma are associated with various non-metastatic syndromes. Rarely, human chorionic gonadotropin may be produced by the tumor. Ectopic gonadotropin production from this source is a rare cause of precocious puberty in boys. Since a report by Behrendt in 1931,... |
Several different tumors in different tissues(including the central nervous system, heart, kidney, liver, bone, and soft tissues) are found to be associated with tuberous sclerosis. In the brain, this tumor characteristically arises from the floor of the lateral ventricle and often occluded the foramen of Monro. Cardiac tumor is among the earliest signs of tuberous sclerosis and occurs in over... |
Invasive diseases caused by Trichosporon beigelii are rare, usually fatal, opportunistic infections that occur exclusively in immunocompromised patients. This fungus has been known to produce cutaneous involvement in immunocompetent hosts, and is rarely reported to cause systemic disease in patients with cardiac valve replacement. In this report, we described a case of invasive Trichosporon beigelii pneumonia in a 9-year-old boy... |
