The radiographic measurement of the renal size and position provide important information of disease of thekidney and the adjacent organs. The author analyzed the 213 cases of intravenous pyelography of normal Koreanchildren from 0 to 18 years of age (135 males and 78 females) and measured the following points; the length of thekidney, the width of the kidney, the level of both hila, and the ratio of the kidney length to the total height ofupper 4 lumbar vertebral bodies plus intervertebral discs. The results were obtained as follows; 1. Above 4 yearsof age, the annual increase rate of the kidney length was 0.31cm, and that of the height of lumbar vertebrae was0.44cm in male and 0.55 cm in female; the height of lumbar vertebrae grew more rapidly than the kidney length. 2.The age group of the most rapid growth in the length and the width of the kidney was 16 to 18 years of age inmale, and 13 to 15 years of age in female, and that of the most delayed growth was 4 to 6 years of age in bothsexes. 3. The size of the left kidney was usually larger than that of the right. But, the right kidney was largerthan the left in 20% of the cases. 4. The right hilum was usually lower than that of the left. In the 12% of thecases, however, the right hilum was higher in position than the left. 5. The width of the kidney in most childrencorresponded to the 45 to 60% of the kidney length. 6. The kidney size in age group between 16 and 18 years waswithin the range of that of normal adults. 7. The ratios of the kidney length to the height of upper 4 lumbarvertebral bodies plus intrevertebral discs were as follows; > 1.1 below 3 years of age. 1±0.1 between 4 and 12 years of age. > 0.9 above 13 years of age.

PURPOSE: The objective of this study was to find the predictors and generate a prediction scoring model of nonresponse to intravenous immunoglobulin in patients with Kawasaki disease. METHODS: We examined 573 children diagnosed with KD at the Severance Children's Hospital between January 2009 and december 2012. We retrospectively reviewed their medical records. These patients were divided into 2 groups; the experimental group (N=433) and the validation group (N=140). Each group were divided into 2 groups the intravenous immunoglobulin nonresponders and the responders. Multivariate logistic regression analysis identified predictive factors of intravenous immunoglobulin nonresponders which make predictive scoring model. We practice internal validation and external validation. RESULTS: Multivariate logistic regression analysis identified male, cervical lymphadenopathy, changes of the extremities, platelet, total bilirubin, alkaline phophatase, lactate dehydrogenase, C-reactive protein as significant predictors for nonresponse to intravenous immunoglobulin. We generated prediction score assigning 1 point for (1) male, (2) cervical lymphadenopathy, (3) changes of the extremities, (4) platelet (< or =368,000/mm3), (5) total bilirubin (> or =0.4 mg/dL), (6) alkaline phophatase (> or =227 IU/L), (7) lactate dehydrogenase (> or =268 IU/L), (8) C-reactive protein (>77.1 mg/dL). Using a cut-off point of 4 and more with this prediction score, we could identify the intravenous immunoglobulin nonresponder group. Sensitivity and specificity were 52.5% and 82.4% in experimental group and 37.8% and 81.8% in validation group, respectively. CONCLUSION: Our predictive scoring models had high specificity and low sensitivity in Korean patients. Therefore it is useful in predicting nonresponse to intravenous immunoglobulin with Kawasaki disease.

Pure red cell aplasia in uncommon disorder characterized by finding of anemia, absence of nucleated red blood cell in the marrow, absence of reticulocytes in the peripheral blood and normal peripheral platelet and leukocytes counts. We experienced one case of pure red cell aplasia associated with hemolytic anemia characterized by hemoglobinuria, reticulocytopenia, and erythroid hypoplasia of the bone marrow. The cause of the illness was not definitely identified, but we concluded that this patient had simultaneous occurrence of PRCA and hemolytic anemia following administration of diphenylhydantoin after craniotomy rather than virus or bacteria induced. The simultaneous occurrence of PRCA and hemolytic anemia in uncommon and the mechanism for diphenylhydantoin induced PRCA and hemolytic anemia is unclear.

To assess the role of multiple factors in influencing occurrence of ventricular premature complexes after acute myocardial infarction twenty-four hour Holter electrocardiographic tape recording were made in 40 survivors of an acute myocardial infarction 10 to 20days after attack. Ventricular premature complexes in the early post infarction period were not correlated with left ventricular function, age, sex, smoking, diabetes mellitus, previous angina, and previous myocardial infarction. The occurrence of ventricular premature complexes showed a positive correlation with the occurrence of ST-T change. The occurrence of ventricular premature complexes during sleep hours was compared to the awake state. In 22 patients, the incidence of ventricular premature complexes are excluded from analysis, the 22 of patients, or in 76 percent, sleep was associated with a lowered occurrence of ventricular extrasystoles.

Dysembryoplastic neuroepithelial tumor(DNET) is a recently described rare tumor that occurs most frequently in the temporal lobe of the brain and is characterized by long-standing, intractable complex partial seizures in children. The authors experienced one case of DNET occurring in a 13-year old boy, who had refractory complex partial seizure for 7 years. CT scan revealed nonenhancing low density mass in the left temporal lobe. MR images demonstrated a well-marginated cortical mass with very low signal intensity on TIWI and multinodular appearance of high signal intensity on T2WI. A few small enhancing foci within the mass were noted on contrast enhanced MR images. DNET, a rare tumor, should be considered in the differential diagnosis of neoplasm which causes seizure and is distinguished from other tumors because of its benign course. Differentiation between DN ETand other tumors by CT and MR findings is very difficult. But, our case showed the multinodular pattern on T2W image, which may be helpful feature in the differential diagnosis.

Candida Albicans is a saprophytic organism under normal circumstances and a limited pathogen when presents in large numbers. The common site of infection are the mouth, skin, vagina and respiratory tract. It is a common inhabitant of the G-I tract, where it does not usually cause symptoms. With impared defense mechanism or long-term antibiotic therapy, however it can became a significant pathogen. The clinical symptoms and endoscopic findings present a spectrum of changes depending on the degree of esophageal involvement. Painful awallowing and substernal chest pain are most common symptoms. Esophgeal infection is an unusual but impartant form of the diseases and can easily be confirmed by esophagoscopy. Recently we have experienced 4 cases of esophageal moniliasis confirmed by esophagoscopy and tissue biopay.

10.Computerization of Patient Data Management for Vology by Automatic Coding System : A Program Using dBASE IV in Personal Computer.
Korean Journal of Urology 1990;31(5):734-740
In recent years there are so many medical informations that urologists should know. Computer systems offer new opportunities for the storage and manipulation of hospital informations. A computer-based system for urologic patient data management has been designed and developed by the authors. This program was written in dBASE IV language and could be used in IBM PC/AT (16 Bit) with at least 20MB hard disk drive. The main features of this program include storage and retrieval of data easily by pull-down menus using automatic coding system for diagnoses and operation names. Searching a case or a group of cases could be performed by name, chart number and filters (date of input, diagnosis code, operation code, urology number). And they are easily printed out by two different print forms. The automatic coding system is that after diagnoses and operation named are typed, their codes are automatically registered. The urologic code system for automatic coding was also designed by the authors. In our experience this computer-based urologic patient data management system by automatic coding is very useful, easy to handle, and minimizing input errors.
