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.

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.

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.

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.

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: 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.

Imaging Science in Dentistry 2020;50(4):359-363
Ameloblastic carcinoma is a rare odontogenic malignant tumor with the histologic features of both ameloblastoma and carcinoma. It occurs more frequently in the mandible than in the maxilla and it may appear de novo or develop from a preexisting ameloblastoma or odontogenic cyst. Rapidly progressing, painful swelling is the most common symptom, and radiographically, it shows significant bone resorption and cortical perforation. This report described a case of ameloblastic carcinoma in a 45-year-old man who presented with swelling in the left mandible. The lesion showed combined features of benign findings, such as an expansile cortex with a distinct border, and malignant findings, such as a large exophytic mass with frank bone resorption. Excisional biopsy was performed and a final diagnosis of ameloblastic carcinoma was made.

Imaging Science in Dentistry 2020;50(4):309-318
Purpose:
This study investigated correlations between findings on panoramic radiographs and cone-beam computed tomography (CBCT) to assess the relationship between the maxillary sinus floor and the roots of maxillary posterior teeth. In addition, radiographic signs indicating actual root protrusion into the maxillary sinus were evaluated on panoramic radiographs.
Materials and Methods:
Paired panoramic radiographs and CBCT images from 305 subjects were analyzed. This analysis classified 2,440 maxillary premolars and molars according to their relationship with the maxillary sinus floor on panoramic radiographs and CBCT images. In addition, interruption of the sinus floor was examined on panoramic radiographs.
Results:
Root protrusion into the maxillary sinus occurred most frequently in the mesiobuccal roots of the second molars. The classification according to panoramic radiographs and CBCT images was the same in more than 90% of cases when there was no contact between the root apex and the sinus floor. When the panoramic radiograph showed root protrusion into the sinus, the CBCT images showed the same classification in 67.5% of second molars, 48.8% of first molars, and 53.3% of second premolars. There was a statistically significant relationship between interruption of the sinus floor on panoramic radiographs and root protrusion into the sinus on CBCT images.
Conclusion
The presence of root protrusion into the sinus on panoramic radiographs demonstrated a moderate ability to predict root protrusion into the maxillary sinus. Interruption of the maxillary sinus floor could be considered an indicator of actual root protrusion into the maxillary sinus.
