PURPOSE: We performed urinary mass screening(UMS) program for 2,804 children of second grade elemantary school 8 years of age in Paju city with cooperation of Paju City Health Center to determine the prevalence of asymptomatic proteinuria and hematuria, and to estimate the risk of incipient renal diseases. Also we attempted to evaluate the significance of hematuria in UMS in addidtion to proteinuria. METHODS: 2,804 children of the 2nd grade of elementary school who lived in Paju city were included to our UMS program in 2000. They were constituted with 1,428 boys and 1,376 girls. The screening program was carried out in 3 steps. The 1st screenig test was performed at schools and then students with abnormal results were examined repeatedly at Paju City Health Center and our hospital. Those students who showed proteinuria and/or hematuria in the 1st and 2nd test were referred to our hospital to undertake the 3rd close examination including physical examination, laboratory tests and radiologic tests. RESULTS: (1) The prevalence of urinary abnormality in the 1st screening test was 8.3%(233 students), comprised of 5.9% of boys, 10.8% of girls. (2) Among 2,804 children tested in the first screening, prevalences of asymptomatic proteinuria and isolated hematuria were 64(2.3%), 163(5.8%) respectively, and the prevalence of proteinuria with hematuria was 6(0.2%). (3) Among 233 students with urinary abnormalities at the 1st screening test, 102 students applied to the 2nd test. 32 children, about one third of them, were also found to have abnormal urinary findings; isolated hematuria 30, proteinuria with hematuria 2. (4) Those findings of clinical evaluation for children with isolated hematuria at the hospital showed as follows: idiopathic isolated microscopic hematuria 21, normal 6, urinary tract infection 1, idiopathic hypercalciuria 1 and simple renal cyst 1. Those 2 students with proteinuria and hematuria seemed to have chronic glomerulonephritis. CONCLUSION: (1) The clinical evaluation for children who showed positive results at the 1st screening test should be done judiciously. Because of high false positive rate, almost who showed positive results was normal, only a few of them had pathologic conditions. In this study, actual incidence of incipient renal diseases in children of 8 year old was calculated to be 0.4%. (2) The definite conclusion whether a urinary mass screening test can alter the prognosis of incipient renal diseases could not be drawn with this study. Further study must be necessary. (3) We could acknowledge the significance of hematuria in UMS, but it is necessary that one should be judicious in managing and follow-up those that show abnormal results.

OBJECTIVES: Copper and Zinc, the trace elements of a living body, take a part in immunologic mechanism and induce the pulmonary fibrosis which is the pathologic progress of pneumoconiosis. This study was performed to assist the identification of the pathologic process of pulmonary fibrosis in pneumoconiosis. METHODS: The subjects of this study was 200 diagnosed persons as pneumoconiosis, of whom 100 persons was the visitors in the outpatients departments of pneumoconiosis and 100 admissive pneumoconiosis patients. The serum copper and zinc are measured and com pared. RESULTS: The mean serum copper concentration of visitor group was significantly higher than that of control group, and that of stage V3 subgroup of visitor group was highest because of their advanced fibrosis. But, there was not the difference of serum copper concentration between patient and control group. We thought that the reason was poor nutritional and health status of the patient. The mean of serum zinc concentration of visitor and patient control was lower than that of control group. As the degree of pulmonary fibrosis was more severe from stage Vl, V2, V3 of visitor to stage Pl, P2, P3 of patient, the mean of serum zinc concentration was lower. The ratio of serum copper/zinc of visitor and patient was higher than that of control, and that of patient was higher than that of visitor. Those results showed that the ratio of serum copper/zinc ratio more greatly expressed the degree of progression of pneumoconiosis than only copper or zinc concentration by adjustment of nutritional and health status of the patient. CONCLUSIONS: As above study results, the degree of pulmonary fibrosis of pneumoconiosis could be estimated by means of serum copper/zinc ratio.

The interstitial lung diseases(ILD) comprises a large, heterogeneous group of disorders characterized by derangement of alveolar walls and alveolar capillary unit causing restrictive pulmonary dysfunction and disordered gas exchange. It is rare, especially in children, and the opinions on investigation and treatments are controversial. The classification of adult ILD is applied to that of children. But considering occurrence during the developing state of lung and immune systems, we should be more cautious because the clinical manifestations and prognosis will be different from those of adults. In 1995, Katzenstein named a unique type of ILD, chronic pneumonitis of infancy (CPI) for the first time. CPI is characterized by marked alveolar septal thickening, striking type II pneumocyte hyperplasia, and eosinophilic alveolar exudate containing numerous macrophages. We report a 14 month-old girl, who had continuing respiratory difficulty and cyanosis after upper respiratory infection, could not sustain oxygen saturation and was finally diagnosed as CPI by histologic examination.

BACKGROUND: In an effort t enhance long term patency of coronary bypass grafts, utilization of arterial conduits have been on an icrease. With the same objective, we have been using the right gastroepiploic artery (RGEA) in coronary artery bypass procedures since 1998. The current paper has been undertaken with the aim of assessing the apropriateness, problems, and short term results of using the RGEA as an arterial graft conduit by studying the postoperative clinical results of 100 patients than received coronary artery bypass grafting (CARG) with this artery. MATERIAL AND METHOD: Between May of 1998 and May of 1999, an analysis of the mortality, postoperative myocardial infarction, and the need for IABP insertion as a result of low cardiac output were made between 100 consecutive patients undergoing CABG with the RGEA. There was one postoperative death due to cerebral infarction. Postoperative complications/morbidity comprised myocardial infarction in 2, cerebral infarct in 3, reoperation due to bleeding in 1, mediastinitis in 1, and low cardiac output syndrome necessitating IABP in 3 patients. Complicatons related to harvesting of the arterial grafts were not experienced in any of the patients. CONCLUSION: The results of the current data show that utilization of the RGEA in CABG is not associated with increased mortality/morbidity and demonstrates satisfactory short term results suggesting the usefulnessof this conduit as an arterial graft.

Our purpose was to evaluate the clinical significance of large (>5cm) placental chorioangioma. Obstetrical and neonatal records which were confirmed chorioangioma in pathology and greater than 5 cm in diameter, were reviewed retrospectively from April. 1, 1991, to March. 31, 1996. 11 cases of placental chorioangioma greater than 5 cm were diagnosed prenatally by ultrasonography except one. I'hey were associated with maternal or fetal complications-6 cases of polyhydramnios, 2 cases of PIH, 1 case of neonatal anemia, 2 cases of preterm birth, 2 cases of neonatal hyperbilirubinemia, 1 case of cardiomegaly, 1 case of IUGR and 1 case of oligohydramnios. Nevertheless, there were not remarkable neonatal morbidity and mortality. These uncommon large tumors were often associated with maternal or fetal complications. But, we could get good neonatal outcome through thorough antenatal surveillance.

It has been estimated that chromosomal aberrations account for 2.3% to 3% of normal pregnancies and of them 85% are aborted. Therefore, the survival rate of neonates with chromosomal aberrations are very low. Patients with partial deletion of the long arm of chromosome 10 are rare. We experienced a case of partial monosomy 10 in a 14-years-old girl. She showed mental and growth retardation, low-set malformed ears, hyperterolism, hypothyroidism and dilated cardiomyopathy. Chromosomal analysis on G-banding with high resolution showed a terminal deletion of the long arm of chromosome 10. Her karyotype was designated as 46, XX, del (l0) (q26). A brief review of literature is also presented.
