BACKGROUND: The purpose of this study was to find the factors associated with becoming obese children during the past 2 years in 6th grade children of elementary school and then to evaluate the high risk groups for childhood obesity. METHODS: The 738 children from May to June, 2001 in 6th grade of 5 elementary schools in Busan were the subjects of this study. The children's height and weight in 4th grade and 6th grade were obtained from school health records. We calculated the body mass index in 4th and 6th grades and classified into 3 weight groups (normal, at risk for obesity, and obese) according to the age and sex-specific BMI established by the Korean Academy of Pediatrics. If children's weight group in 4th grade was changed to heavier weight group in 6th grade, we defined it as increased group. Otherwise, we defined it as non-increased group. The association between the increase in weight group and parental and children's characteristics were analyzed by x2-test, x2-test for the trend, t-test, ANOVA and multiple logistic regression. RESULTS: Among the total, 3.3% of children with normal weight and 16.9% of children at the risk for obesity in 4th grade were transformed to increased group in 6th grade, respectively (P<0.001). Children who had excessive appetite (P<0.001), watched TV greater than or equal to 2 hours per day (P=0.004) or had an obese father (P=0.044) were more likely to become increased group. After adjusting for father's obesity, appetite and TV watching time in children, the odds ratio of transforming to increased group after 2 years in children at risk for obesity or in obese child in 4th grade was 2.5 (95% CI: 1.09~5.55) compared to children with normal weight. Children having excessive appetite were 3.2 times (95% CI: 1.42~7.01) more likely to become the increased group after adjusting for father's obesity, TV watching time and weight in 4th grade. Children watching TV greater than or equal to 2 hours/day was 2.8 times (95% CI: 1.27~6.18) more likely to become increased group after adjusting for father's obesity, appetite and weight in 4th grade. CONCLUSION: The risk of becoming obese was higher in children at risk for obesity or obese children in those with excessive appetite or those who have watched TV> or =2 hours/day for the past two years. These findings suggest promotion of educational plan to prevent childhood obesity.

BACKGROUND: The purpose of this study was to assess the lifestyle associated with weight gain and persistent overweight for 2 years. METHODS: The subjects were 580 workers (109 men, 471 women) at one university affiliated hospital. Their height and weight were measured twice in 2000 and 2002. A questionnaire, about lifestyle was filled out in 2000. The questionnaire included the average amount of alcohol intake and the number of days per week in which alcohol was consumed, smoking status, and the number of days per week in which exercise was done. Their weight change in 2 years was calculated and their weight status was classified into two groups: persistent normal weight (BMI <23 kg/m2) and persistent overweight (BMI> or =23 kg/m2). RESULTS: Among the total, 54.3% of men and 10.0% of women had persistent overweight over 2 years. Overall 93.4% of overweight men and 68.7% of overweight women remained overweight after 2 years. Compared with male non-smokers and male ex- smokers, current male smokers gained weight as much as 1.17 kg over 2 years after adjusting for age and initial BMI (P=0.033). Compared with females who exercised less than 3 per week, those who exercised 3 or more per week lost weight as much as 1.21 kg over 2 years after adjusting for age and initial BMI (P=0.005). Compared with males who consumed alcohol an average of< or =30 g per consumption, those who consumed an average of > 30 g were 4.1 times (95% C.I. 1.04~16.21) more likely to maintain persistent overweight over 2 years after adjustment for age and frequency of alcohol use. However no particular lifestyle was shown to predict the risk of persistent overweight for women. CONCLUSION: Regular exercise of moderate intensity and modest alcohol consumption seemed to prevent weight gain and persistent overweight. Such lifestyle may be encouraged to maintain healthy weight.

Leiomyosarcoma is extremely rare in the oral cavity and especially in the mandible. At first, the case of this report was diagnosed as odontogenic fibroma but after approximately 3.5 years, it was diagnosed as leiomyosarcoma. Conventional radiograph of the first time showed an ill-defined radiolucent lesion in the mandible. After local recurrence, CT images showed a large irregular soft tissue mass with some necrotic areas. These findings were not specific for leiomyosarcoma, but they suggested that this lesion was a recurrent soft tissue sarcoma. Histopathological examinations using H & E staining, immunohistochemical staining and Masson's trichrome staining confirmed this case as leiomyosarcoma. Deciding its malignany or benignancy, defining the tumor extent and its relationship to the surrounding anatomic structures, and evaluating the distant metastasis are more important role of radiographic examination than finding out the name of disease.

Background: The purpose of this study was to evaluate the effectiveness of telephone call reminder on retention rate in obese patients. Methods: A total of 118 patients (85 first-time visitors, 33 re-visitors), who visited an obesity management clinic from May 2003 to May 2004, were divided into the intervention group (n=64) and the comparison group (n=54). The intervention was a telephone call reminder before the appointment date. The retention rate up to 7th visit and body mass index were compared between the two groups. Results: The retention rate was 64.4% at 4th visit (after 66.5+/-29.2 days from the first visit) and 36.4% at 7th visit (after 142.1+/-57.8 days from the first visit). For the first- time visitors, the retention rate at 3rd visit was significantly higher (85.1%) in the intervention group than those in the comparison group (67.6%, P=0.049). Otherwise, there were no significant differences in retention rate and body mass index at each visit between the two groups regardless of the visiting status. However, the body mass index at 4th and 7th visit was significantly lower in the intervention group than in the comparison group among the first-time visitors who completely attended 7 times (P=0.031). Conclusion: We could not find the telephone call reminder to be an effective method to improve retention rate in obesity management clinic. Further intensive approach is needed to promote attendance.

BACKGROUND: It has been found that parental role is essential for obesity management in childhood. However, there are few studies concerning parental perception on childhood obesity in Korea. Parental perception on childhood obesity according to weight status in elementary school children was examined. METHODS: The subjects were 3,996 elementary school children and their parents in Busan. The surveys which included socioeconomic characteristics, children's eating habits and activities, parental weight and height, parental perception on childhood obesity, were filled out by parents. Children's body mass index (BMI) were calculated using the height and weight measured in school children were classified into the obese group (BMI 95 Percentile) , the high risk group (85 percentile BMI <95 percentile) and the normal weight group (85 percentile) according to BMI gender and age. The analyses were done using x2_ test and ANOVA. RESULTS: Parental BMI in the obese group was higher than the normal weight group in boys a girls (P<0.001) . Participation in regular exercise was higher among the obese group compared to the normal weight group regardless of sex, but daily exercise time was lesser among the obese group only in boys (P <0.001) . Daily TV watching time was not different according to weight status in both sex. The parents with obese children perceived their children's weight as an appearance problem or a health problem about 7-18 times more likely than the parents of children with normal weight. 70% of obese children have tried weight control. The proportion of parental understanding on childhood obesity as a disease was not different among boys, but different among girls (P<0.001) . Eighty five percents of the parents perceived childhood obesity as a disease or a risk factor. But, their perception for the association of hypertension, fatty liver, sleep apnea syndrome with obesity was relative low. CONCLUSION: Most parents with obese children perceived childhood obesity as an appearance problem, a health problem and as a disease or a risk factor.

We report a case of the isolation of the Aspergillus versicolor complex, initially misidentified by morphological characteristics as the Scopulariopsis species, from a homograft with a bicuspidalized pulmonary valve. An eighteen-month-old female, who had critical pulmonary stenosis, underwent pulmonary valve replacement. On postoperative day 8, she developed a fever, which did not respond to empiric broad-spectrum antibiotics. While no definitive source was identified, a filamentous fungus was isolated from the thawed homograft tissue culture prior to implantation on the operation day. The colonies were powdery green with white edges on Sabouraud dextrose agar. Microscopic examination showed septate hyphae with branched conidiophores and chains of spiny conidia, which suggested Scopulariopsis species. After direct sequencing of the internal transcribed spacer (ITS) regions, the fungus was identified as the A. versicolor complex. To our knowledge, the isolation of the A. versicolor complex from a homograft valve has not been previously described. This case shows that laboratory staff should be aware that microscopic morphology of the A. versicolor complex can resemble that of a number of other genera, including Scopulariopsis species.

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract, but also occurs at a lower frequency in extra-gastrointestinal regions such as omentum, mesentery, retroperitoneum and undefined abdominal sites. This tumor is called extragastrointestinal stromal tumor (EGIST). EGIST is mostly diagnosed as a cystic mass, but rarely occurs as a disseminated abdominal tumor. We experienced a 70-year-old man with primary EGIST presenting as peritoneal dissemination. Abdominal CT showed diffuse peritoneal thickening with a large amount of ascites, but no definite mass lesion. Laparoscopic biopsy was performed and histologic findings showed tumor composed of epithelioid cells. In the results of immunohistochemical stains, the tumor showed positive reactivity with CD117 (c-kit), CD34, vimentin and actin, but negative reactivity with desmin and S-100 protein. On account of unresectability and histologic parameters of malignant behavior, he was started on imatinib.
