Purpose : This study was carried out to obtain the immunization rate of MMR, and to know the related factors. Methods : Subjects of the study were 3,364 students of 8 elementary schools of Kyonggi province. Surveys accompanied with questionnaires were conducted in 1996 and 1999, respectively. Results : The salient features of the findings were as follows : The immunization rate... |
Purpose : The reasons for breast feeding failure within the first month of birth were related to inappropriate handling of problems in breast feeding. We investigated common reasons for the failure during the neonatal period and assessed medical personnels` attempts to solve them. Methods : We conducted a survey with a prepared questionnaire on one-hundred-twenty mothers who failed in breast feeding... |
Purpose : Receptors for the Fc of IgG(FcγR) and a β2 integrin molecule, CD11c/CD18 are important in clearance of microbes by granulocytes. We performed an in vitro study on the effect of recombinant human granulocyte colony-stimulating factor(rhG-CSF), or granulocyte-macrophage colony-stimulating factor(rhGM-CSF) on the expression of FcγR II, FcγR III, CD11c and CD18 and respiratory burst function of granulocytes. Methods : Peripheral... |
Purpose : The increasing prominence of pneumococcal infections and of antimicrobial resistance has emphasized the need for a effective vaccine to reduce the risk of pneumococcal disease in childhood. To study the antibody response of pneumococcal vaccine, we compared the concentration and opsonophagocytic capacity of antibodies to the capsular polysaccharide of S. pneumoniae serotype 19F in sera from healthy adults... |
Purpose : Inhaled nitric oxide(iNO) is an excellent method for the postoperative pulmonary hypertension in congenital heart disease. But more detailed care is needed because of the development of rebound pulmonary hypertension after NO withdrawal. We performed this study in order to discontinue the iNO successfully by way of presenting the adequate weaning and supplying methods. Methods : Between January, 1998... |
Purpose : The object of this study is to determine whether QT interval variability in patients with postoperative tetralogy of Fallot increases. Methods : We enrolled 41 patients who had total correction of tetralogy of Fallot, and 31 healthy controls. They were 6-12 years old. Patients were divided into 2 groups : arrhythmia-positive patients(n=10) who had ventricular premature contractions more than... |
Purpose : The diagnosis of hypertrophic pyloric stenosis(HPS) can be made by clinical manifestations and upper gastrointestinal(UGI) series in most cases. Recently, the ultrasonogram(US) is a more accurate and reliable method for the diagnosis of HPS in early stage. Methods : We retrospectively studied 27 HPS patients confirmed surgically from January 1999 to March 2000. We reviewed clinical histories and physical and laboratory findings.... |
Purpose : The developing brain has been reported to be extremely susceptible to toxicity of ischemia and/or hypoxia during a restriced developmental period. Hippocampal neuronal cell death is a typical type of perinatal hypoxic brain lesion and often coexists with other forms of cerebral hypoxic injuries. In the present study, we examined whether transcriptional changes of NR2A and NR2B subunits... |
Purpose : Williams syndrome(WS) is an autosomal dominant disorder resulting from a submicroscopic deletion of contiguous genes on the long arm of chromosome 7. We evaluated the physical, neurodevelopmental, and behavioral characteristics of children and adults with WS confirmed by fluorescence in situ hybridization. Methods : The clinically suspicious twelve cases with cardiac anomaly were confirmed as WS with fluorescence in... |
Purpose : The following study has been carried out to find the symptoms of hypoglycemia and the symptoms of transient focal neurologic deficit, which were complained by insulin dependent diabetes mellitus patients and their parents. Methods : The subjects of this study were 16 insulin dependent diabetic patients who were admitted to the pediatric department of Samsung Medical Center. From the... |
Polyarteritis nodosa(PAN) is a multisystemic disease primarily involving the small and medium- sized vessels. Prognosis depends on the presence and severity of visceral involvement. Gastrointestinal involvement in PAN may result in vague abdominal pain, nausea and melena. Angiography can be used to establish a diagnosis of PAN. We report a case of polyarteritis nodosa presenting with recurrent abdominal pain, melena... |
We experienced a case of isolated fetal pleural effusion diagnosed by antenatal ultrasonogram in the 33th week of gestational age. Chest PA at birth showed massive pleural effusion in both lungs. The serous pleural fluid changed to a milky nature after feeding so we diagnosed it as congenital chylothorax. The infant was managed by chest tube drainage, NPO & TPN... |
Tsutsugamushi disease is acute febrile illness, transmitted by Rickettsia tsutsugamushi. R. tsutusgamushi invade and proliferate in the endothelial cells of small blood vessels. Destruction of endothelial cells occurs from the proliferation of the organism and eventual disruption, and thus vascular rich organs must be carefully examined such as the kidney, lung, heart, liver. Recently we experienced a case of acute... |
Maple syrup urine disease(MSUD) is an autosomal recessive disorder involving the metabolism of the branched-chain amino acids(BCAA) such as leucine, isoleucine and valine. The disorder is due to a defect in branched-chain α-ketoacid dehydrogenase(BCKAD) and the classic form causes rapid progressive and overwhelming illness beginning in the first weeks of life, present with poor feeding, lethargy, change in muscle tone,... |
This is the first reported case of a unique interstitial deletion involving the long arm of chromosome 17 in a Korean male infant born to parents with normal karyotype. The patient presented with multiple congenital malformations suggestive of chromosomal anomaly including round face, upslanted palpebral fissure, hypertelorism, posteriorly rotated low set ear, micrognathia, microcephaly, finger- like thumb, bilateral hearing loss,... |
