A case-control study was conducted to identify the specific risk fatctors for hemorrhagic fever with renal syndrome(HFRS) in Korean soldiers. The case group consisted of 196 confirmed HFRS patients who were admitted to the Capital Armed Forces General Hospital between I November 1989 and 15 January 1992 and were 25 years old or younger. The control group consisted of 258 non-HFRS patients who were admitted to the same hospital and meeting following conditions; onset of symptom was within five days before or after the onset date of case, had regular military activities up to the onset of symptom, and no noticeable signs for the diagnosis. Most of the cases and controls came from the units located in Kyonggi province (61.7% of cases, 75.9% of controls) and Kangwon province (31.6% of cases, 15.5% of controls). The distribution of places where the cases and controls had moved into during 60 days period prior to admission was similar to that of the base units. Among 196 cases, 89.3% occurred in October through December and 46.9% in November. Significant risk factor was the field living condition. The odds ratio (OR) for sleeping in a tent vs not sleeping in a tent during 60 days period prior to admission was 1.55 (95% CI=1.07-2.25) and that for sleeping on the bare ground or in a vehicle was 3. 63 (95% CI=1.48-8.86). Other statistically significant risk factors were advanced tac tical training (OR=1.51, 95% CI=1.02-2.24), drinking surface water (OR=1.83, 95% CI=1.21-2.77), exposure to indoor dust (OR=1.58, 95% CI=1.05-2. 37), fixing trench (OR=1.63, 95% CI=1.12-2.37) and having seen Apodemus in the outdoors (OR=4. 61, 95% CI=2.12-10.02). Most of these risk factors were related with camping (field living condition) and thus the interaction between each risk factor and camping was examined by cross tabulation. None of the ORs for five risk factors was statistically significant for the cases who had no camping. However all of the ORs for the cases who had camping were increased and statistically significant ;2.27 for advanced tactical training, 2.64 for drinking surface water, 2.14 for exposure to indoor dust, 2.91 for fixing trench, and 7.58 for having seen Apodemus in outdoors. It was revealed in this study that the highest risk factor for HFRS is camping in the area where the Apodemus inhabits.

This study was conducted to investigate the food behavior during the childhood, the influence of food behavior on internalizing and externalizing behavior problems, and the pattern of influence of food behavior on behavior problem depending on children's age and gender. A total of 171 children aged 5 and 6 years were selected who attended 3 nurseries and 1 kindergarten in Seoul, and the survey data responded by teachers were analyzed. The results were as follows. First, children with higher levels of food behavior showed less internalizing behavior problems compared to those with lower levels of food behavior. The main effects and interaction of gender and age were not significant. Second, children with higher levels of food behavior showed less externalizing behavior problems compared to those with lower levels of food behavior. For hyperactivity, interaction of age and food behavior was significant, and age and the interaction of age and food behavior affected children's agression. Food behavior of children affects behavior problem and, therefore, children with better food behavior showed less behavior problems in the same circumstances.

The purpose of this study was to review the clinical features, histological types and the mode of treatment of malignant gynecologic tumors. Retrospective reviews of the medical recordings for 75 cases with malignant gynecologic tumors in department of Obstetrics and Gynecology, Kuri hospital Hanyang University from July. 1, 1995 to Jun. 30. 2000. We analysed clinical characteristics, stage, histopathologic type and treatment modality. Of 75 cases, 44 cases were carcinoma of the uterine cervix, 21 cases were ovarian cancer and 10 cases were uterine cancer. The mean age of cervix cancer is 53.3 years, ovarian cancer is 50.9 years and uterine cancer is 49.5 years old. The main treatment modality of cervix and uterine cancer were surgery followed radiotherapy and ovary cancer was surgery plus adjuvant chemotherapy. However, as the number of patients were small in our study, further study with large number of patients are warranted.

A total of 150women with singleton pregnancies who were delivered between 37 and 42weeks gestation had ultrasound scans on elective cesarean section day. The biparietal diameter(BPD), head circumference(HC), abdominal circumference(AC) and femur length(FL) were measured in all cases. Equations of estimated fetal body weight(BWT) for Korean term fetuses using AC alone, BPD/AC, AC/FL, HC/AC/FL, BPD/AC/FL, BPD/HC/AC/FL were made by stepwise multiple regression analysis and were compared with foreign equations such as Campbell(AC), Shepard(BPD/AC), Hadlock I(AC/FL), Hadlock II(HC/AC/FL), Hadlock III(BPD/AC/FL), and Hadlock IV(BPD/HC/AC/FL). The results were as follows. 1. The equations of BWT by sonographic measurement were Equation1 (AC) logeBWT=6.105936+0.005957X(AC) (R=0.876) Equation2 (BPD,AC)logeBWT=6.53614548+0.00004963X(ACXBPD) (R=0.929) Equation3 (AC,FL) logeBWT=6.25336442+0.00751602X(FL)+0.00005155X(ACXFL) (R=0.950) Equation4(HC,AC,FL) logeBWT=6.39631346+0.00004823X(ACXFL)+0.00002023X(FLXHC) (R=0.953) Equation5(BPD,AC,FL) logeBWT=5.99934074+0.00871394X(BPD)+0.00005132X(ACXFL) (R=0.960) 2. When BPD, AC and FL were measured, the addition of HC didn,t affected to accuracy of EFW 3. The best results of all equations were obtained with our equation 5(Mean error=2.36gm, Mean absolute error=96.39gm, Mean deviation + SD(%)=0.07+0.37) and among foreign equations, the best results were with Hadlock III equation(Mean error=18.35gm, Mean absolute error=107.82gm, Mean deviation + SD(%)=-0.46+0.42) 4. The equations using AC/FL (our equation 3, Hadlock I) are more accurate than those using BPD/AC (our equatione 2, Shepard) when utilizing two parameters. Therefore, equation using AC/FL is recommended when the BPD is unobtainable at term or labor 5. The percentage of cases in which the EFW was within +5% and +200gm of the actual birth weight was highest at our equation 5 for 82% and 89%, Hadlock IV equation for 79%, 88%. 6. Our equations had relatively an equal tendency to under- and overestimate fetal weight, but foreign equations, especially Campbell and Hadlock II equations tended to underestimate. 7. Analysing according to actual birth weight, our all equations gave the most accurate estimates of fetal weigh for birth weight group between 3000-3499gm, but for birth weight group above 3500gm, that was not. At birthweight group above 3500gm, the equations depend on femur length are more accurate than the equations independ on fumr length.

PURPOSE: The purpose of this study was to measure the buccal bone thickness and angulation of the maxillary incisors and to analyze the correlation between these parameters and the root position in the alveolar bone using cone-beam computed tomography (CBCT). MATERIALS AND METHODS: CBCT images of 398 maxillary central and lateral incisors from 199 patients were retrospectively reviewed. The root position in the alveolar bone was classified as buccal, middle, or palatal, and the buccal type was further classified into subtypes I, II, and III. In addition, the buccolingual inclination of the tooth and buccal bone thickness were evaluated. RESULTS: A majority of the maxillary incisors were positioned more buccally within the alveolar bone, and only 2 lateral incisors (0.5%) were positioned more palatally. The angulation of buccal subtype III was the greatest and that of the middle type was the lowest. Most of the maxillary incisors exhibited a thin facial bone wall, and the lateral incisors had a significantly thinner buccal bone than the central incisors. The buccal bone of buccal subtypes II and III was significantly thinner than that of buccal subtype I. CONCLUSION: A majority of the maxillary incisor roots were positioned close to the buccal cortical plate and had a thin buccal bone wall. Significant relationships were observed between the root position in the alveolar bone, the angulation of the tooth in the alveolar bone, and buccal bone thickness. CBCT analyses of the buccal bone and sagittal root position are recommended for the selection of the appropriate treatment approach.

PURPOSE: Vitamin D dependent rickets (VDDR) is a rare, autosomal recessively transmitted disorder characterized by hypocalcemia, hypophosphatemia, increased alkaline phosphatase, secondary hyperparathyroidism and many other clinical features. Type l VDDR arises from primary deficiency in the renal 1alpha-hydroxylase that produces 1,25 (OH)2D3. So patients with type I VDDR require life long administration of vitamin D. METHODS: There had been 6 children (4 boys and 2 girls) who were diagnosed as type I VDDR in the Department of Pediatrics, Seoul National University Children's Hospital from March 1983 to May 1997. The medical records, Clinical findings, laboratory, radiologic findings, and response to therapy of these children were analyzed retrospectively. RESULTS: The median age at diagnosis was 19.5 month, and 2 families (33.3%) had family history of rickets. The major presenting symptoms were bowing leg (100%), short stature (100%), and hypocalcemic tetany (67%). Serum levels of 1,25 (OH)2D3 7.0 3.06pg/mL (normal : 20-76pg/mL), respectively. Pretreatment serum levels of calcium (6.9 1.67mg/mL), phosphate (6.9 1.67mg/mL) and alkaline phosphatase (1892 966.4IU/L) were returned to normal levels after treatment (P<0.01). The height standard deviation scores (Z scores) were increased significantly, also (P<0.01). The side effects detected during vitamin D ttherapy were hypercalcemia (33%), hypercalciuria (67%) and nephrocalcinosis (50%). CONCLUSION: This is the first report of type I VDDR in our country. All patients revealed the characteristic clinical, laboratory and radiologic findings, and one third of patients had positive family history. The treatment improved all the clinical, laboratory and radiologic findings significantly including growth. However, complications developed in some patients during the long- term therapy of vitamin D.

PURPOSE: To investigate how the effect of bilateral rectus muscle recession changed by analyzing the effect/dose ratio of surgery according to the preoperative angle deviation.METHODS: We retrospectively studied the medical records of patients from January 2007 to March 2014 who underwent bilateral lateral rectus muscle recession and who visited our hospital for at least 2 years after surgery. We classified the patients into two groups: the preoperative large angle deviation group (35 prism diopters [PD] or more) and the small angle deviation group (20 PD or less). We observed exodrift patterns by measuring distant and near angle deviation according to the preoperative and postoperative times. The effect/dose ratio of recession was calculated at each visit. Surgical success was defined as an alignment between 10 PD of exodeviation and 5 PD of esodeviation, both at distance and at near.RESULTS: Among 165 patients, 84 patients were in the large angle deviation group and 81 patients were in the small angle deviation group. Preoperative angle deviation of the large angle deviation group was 39.34 ± 5.13 PD (range: 35–55 PD) and the small angle deviation group was 19.49 ± 1.62 PD (range: 18-20 PD) (p < 0.001). At postoperative 1 day, the alignments of eyes of the two groups were −8.32 ± 9.31 PD and −13.11 ± 6.94 PD; p < 0.001, respectively. At the date of the final follow-up, the alignments of eyes of the two groups were 4.63 ± 8.94 PD and 1.22 ± 8.01 PD; p = 0.011, respectively, and the effect/dose ratios were 2.25 ± 0.62 PD/mm and 1.94 ± 0.78 PD/mm, respectively, which meant that the effect of correction for the large angle deviation group was larger than that of the small angle deviation group (p = 0.005). Both groups showed postoperative exodrift patterns and similar success rates (75.0% and 80.2%, respectively), which showed no significant difference (p = 0.268).CONCLUSIONS: The small angle deviation group showed a larger effect of correction and high exodrift pattern at the postoperative initial time and the large angle deviation group showed a smaller effect of correction and low exodrift pattern at the postoperative initial time. The preoperative angles of deviation and the operative success rates were not related.

Coronary artery steonosis can be effectively treated by non-operative percutaneous tansluminal coronaryangioplasty(PTCA). We performed PTCA in three patients with coronary artery stenosis, who were referred to thedepartment of radiology, from January to Dec. in 1985. The results were as follows; 1. The locations of coronaryartery stenosis were the proximal anterior descending branch of left coronary artery. 2. The number of stenoticlesions was single without calcium plaque in all three cases. 3. The extent of coronary artery disease is focal,under 2cm in length. 4. PTCA was performed successfully with satisfactory post-dilatation results in all cases. 5.Severe complications such as arterial intimal dissection, acute myocardial infarction, did not occurred. PTCA hasmany advantages over vascular surgery on surgical, economical, and psychological aspects.
