| Purpose : There was marked decline of measles outbreak in the world since the first measles vaccine had been introduced. Recently, however, measles outbreak in the vaccinated children have been reported worldwide, which was ascribed to the possibilities of primary or secondary vaccine failure. We investigated the incidence in the school-aged children in the Kyong-gi Do area, the larger district... |
| Purpose : Neonatal pulmonary function test(PFT) adds a new dimension to the understanding and care of the infant at risk for lung dysfunction. PFT can be identified the risk for pulmonary problems and safely and effectively diagnosed, quantified, and qualified the dysfunction. So it is possible to early institution of prophylatic respiratory therapy in such neonates and it can improved... |
| Purpose : There has been no nationwide report pertaining to the epidemiology of aseptic meningitis, although a great numer of patients have been diagnosed of the illness. Therefore, we report an explosive outbreak of aseptic meningitis occured in a nationwide scale in 1993. Methods : Aseptic meningitis epidemiology surveillence was performed retrospectively on the patients diagnosed of aseptic meinigitis from January... |
| Kawasaki disease may be associatde with a variety of hematologic abnormalities, the most characteristic being thrombocytosis. Thrombocytopenia, in contrast, appears to occur rarely in children with this disease. Hera et al observed the 2% manifested thrombocytopenia early in their illness. To our knowledge, early thrombocytopenia has not been reported in other populations, We report the case of a children with... |
| Purpose : Cushing syndrome occurs rarely in children and adolescents. The clinical manifestation is variable and growth is usually adversely affected. Methods : We retrospectively analyzed 8 patients with Cushing syndrome between the ages of 1 and 14 year who were admitted to the pediatric department of Seoul National University Children's Hospital during the period from 1978 to 1995. Results : 1)... |
| Purpose : Several studies recently have emphasized the value of sonography as an new therapeutic method for hydrostatic reduction of intussusception by using a saline enema under ultrasound guidance.

| The recognition that deletion of 22ql1 is a common cause of varied malformations and clinical disorders took more than a decade to achieve. Deletions of chromosome 22ql1 have been seen in association with DiGeorge syndrome (DGS) and velo¡ⓒ cardio-facial syndrome (VCFS). The large clinical overlap between DiGeorge syndrome and velo-cardio-facial syndrome suggest an aetiological connection. CATCH 22 synd¡ⓒrome is characterized... |
