Purpose : Down syndrome, the most common single cause of mental retardation, is usually due to meiotic nondisjunction leading to trisomy 21. In order to understand the mechanisms of meiotic nondisjunction including parental origin of an extrachromosome and the meiotic stage of nondisjunction, we have studied DNA polymorphisms at loci on the long arm of chromosome 21 in 36 families with free trisomy 21. Methods... |
Purpose : The need for analgesia in neonates during and after surgery has been widely accepted in the past decade. Pain relief and sedation are still rarely used during minor treatment procedures in the neonatal intensive care units. However, many diagnostic and treatment procedures in the neonatal intensive care unit are noxious and often painful, and highly stressful for sick neonates. Methods : A prospective... |
Purpose : Neonatal jaundice is one of the most common problems in our country leading to hospitalization. Agar is low cost, low risk, and easily fed orally; it can bind bilirubin in the intestine, decreasing its enterohepatic circulation, thereby decreasing serum bilirubin levels. At present, however, the effectiveness of agar in the prevention and treament of neonatal jaundice is quite conflicting and controversy. Recently we... |
Purpose : With the recent advent of surfactant replacement therapy, there is an increasing need for a rapid and reliable test to predict respiratory distress syndrome (RDS) immediately before or at birth. There are many investigations and methods for the detection of RDS in prenatal or postnatal period. The stable microbubble rating test (SMR-test) developed by pattle et al. is rapid and simple test... |
Purpose : The prevalance rate of chronic hepatitis B viral infection in children is high in our contry. We performed a prospective study to evaluate the effectiveness of and the factors predictive of response to interferon-alpha therapy in children with chronic hepatitis B. Methods : Thirty-two children with chronic hepatitis B werew admitted to the Department of Pediatrics, Yonsei University College of Medicine from... |
Purpose : The role of H. pylori in the pathogenesis of recurrent abdominal pain in children is uncertain. In order to find a correlation between H. pylori infection and recurrent abdominal pain in children, the present study was designed to compare the clinical manifestations between recurrent abdominal pain children with and without H. pylori infection and to investigate the effects of H. pylori eradication... |
Purpose : Thin glomerular basement membrane (TGBM) disease is now recognized as one of leading causes of isolated microscopic hematuria, regarded as a benign condition and characterized by the presence of familial benign hematuria. But there are few studies of TGBM in Korea. The purpose of this study was to evaluate the clinical and pathological findings in TGBM according to... |
Purpose : IL-1β and TNF-α are important mediators of the inflammatory response in serious bacterial infections. The mucosal and systemic IL-1β and TNF-α responses to urinary tract infection are analyzed in children with acute urinary tract infection. Methods : We studied the levels of these two cytokines in the urine and sera of 21 children at diagnosis and after treatment with sandwich ELISA method. Results... |
Purpose : Juvenile myoclonic epilepsy, juvenile absence epilepsy, and epilepsy wth generalized tonic clonic seizure(GTCS) on awakening are the three syndromes of idiopathic generalized epilepsy of adolescent onset currently included in the classification of epilepsy syndromes of the International League Against Epilepsy(ILAE). Although they differ in their predominant seizure types, the syndromes share several seizure types. Also, there are no unique electrophysiologic or genetic markers.... |
The “band heterotopia” or “double cortex” is a brain anomaly that is presumed to result from a premature arrest of neuronal migration. Generalized disorders of neuronal migration to the cerebral cortex have been recognized since the end of the 19th century. Recently, development of neuroimaging technique, such as MRI, have permitted easy diagnosis of generalized neuronal migration disorder. This syndrome is prevalent in females. Most... |
Choledochal cysts are congenital or acquired lesions of the biliary tree with a cystic dilatation of the bile duct. We experienced a choledochal cyst accompanying acute pancreatitis caused by anomalous pancreaticobiliary ductal union(APBDU) in a 2 year old boy. The choledochal cyst associated with APBDU is rarely encountered in the clinical field, and thus we report this case with the presentation of abdominal ultrasonogram, computed... |
Authors experienced a case of Morquio’s syndrome accompanied by respiratory failure in a aged fifteen year old boy. Patient showed normal intelligence, but stunted growth with short trunk and unproportionately large head, pectus carinatum, kyposcoliosis, muscular weakness, paralysis and genu valgum. No other member of family was affected with this syndrome. There were radiological findings of subluxation between first and second cervical vertevrae, central beaking with... |
Chronic granulomatous disease is a group of rare disorders characterized by a disease of oxidative metabolism of phagocytes with deficit of antimicrobial activity. Also, it has clinical features of chronic pyogenic infection, granuloma formation, hypergammaglobulinemia, anemia and leukocytosis. We experienced a case of chronic granulomatous disease with chronic recurrent infection, hypergammaglobulinemia and liver abscess. It was confirmed by modified NBT test. The result of patient' s... |
Infectious mononucleosis is an acute infectious disease occurring predominantly in older children and young adults due to primary Epstein-Barr virus infection. The clinical picture is extremely variable in both severity and duration. The disease in children is generally mild. It is characterized clinically by fever, exudative or membranous pharyngitis, generalized lymphadenopathy, and splenomegaly. Rarely, it complicates neurologic involvement such as cranial nerve palsy, meningoencephalitis, and... |
