Tumoral calcinosis was coined by Inclan in 1943 and thereafter about 40 cases have been reported in the literature, but there has not been reported on a case which involved knee joints. The majority of cases hitherto reported were found in Negro. There was no report in yellow race. Authors presented a case of tumoral calcinosis that involved boih knee joints of a 55 years old Korean housewife. On physical examination chronic draining sinuses with spontaneous extrusion of calcific material was noted on the left infrapatellar region. A radiograph of the both knees showed dense, multinodular deposits of calcium. The masses were confined to the soft tissues; the contiguous joint showed no pathological change. En-block excisianal biopsy was done. The histological section of the excised mass disclosed the foreign-body giant cell with inflamed connective tissue surrounding calcific deposits.

PURPOSE: This research was conducted to compare the effects of an obesity control program on knowledge of obesity, diet habit, exercise habits, and weight loss of children in a pediatric and adolescent psychiatric hospital. METHODS: A non-equivalent control group non-synchronized design was used for this study. Eighteen patients were participated in the experimental group and seventeen were participated in the control group. For 8 weeks, the experimental group received the interventions for fifty minutes weekly, which were consisted of knowledge of obesity, diet habit, and exercise habits and weight loss, while the control group received the usual care during the same period. The outcome variables were measured before and after the program. Data were analyzed using t-test with SPSS/WIN 18.0. RESULTS: The experimental group showed more significant improvement in knowledge of obesity, diet and exercise habits than the control group, but weight loss was not different between the groups. CONCLUSION: To be more effective obesity control program, nurses should collaborate with other staffs including doctors and social workers, and consistently educate the families of the patients.

The purpose of this study was to identify school dieticians' perceptions on the Potentially Hazardous Food (PHF) and the inspection of food safety and sanitation conducted by Provincial Office of Education. Questionnaires were distributed to 400 school dieticians in elementary schools in Seoul and Gyeonggi Province, and 217 responses were collected. The majority of respondents (64%) defined PHF as food that easily decays at room temperature and over half of the respondents considered Korean cooked vegetables as a PHF. In addition, 4% of respondents completely excluded PHFs from their menus. Forty five percent of the respondents selected CCP rule 7 (delivery and distribution process) and 34% selected CCP rule 6 as the most difficult of the CCP rules to follow. Also, perceptions concerning food safety inspection and sanitation were not high in terms of validity, objectivity, and reliability among the evaluation criteria. The study results suggest that PHF as well as Potentially Hazardous Menu (PHM) definitions and guidelines should be re-established in consideration of traditional Korean food culture and the preparation of Korean foods.

Endoscopic injection sclerotheraphy(EIS) was an effective method for treatment of bleeding esophageal varices. However, it might be associated with some undesirable complications. Endoscopic variceal ligation(EVL) is a recently developed method for control of active variceal bleeding and eradicating esophageal varices with similar efficacy and minimal risk of complications compare to EIS. We performed EVL in 40 patients who had recently bled from esophageal varices. Total 198 variceal ligations were performed during 64 separate EVL session. Control rate of acute bleeding was 90%(36 of 40patients) and 4 patients died after EVL because of failure of bleeding control. Rebleeding following initiation of EVL occured in 5 patients-three patients were successfully controlled by EVL, one patient was controlled but eradication was impossible and one patient died. Varices were eradicated or reduced to grade I in 31(86.1%) of 36 survivors by 1-9 ligation(mean 5.0) in l-4 EVL sessions(mean 1.6). After EVL, there were mild complications-mild substernal discomfort in 4 patients, mild dysphagia in 2 patients and fever in 2 patients. These results suggest that EVL is a safe and effective method for treatment of bleeding and eradication of esophageal varices with less complication.

BACKGROUND: This study investigates the prevalance of HBV precore mutant in chronic B hepatitis patients and whether HBV precore mutants affect hepatic inflammation and response to interferon alfa. METHODS: HBV DNA in liver tissue from 48 chronic hepatitis patients was amplified by polymerase chain reaction. The HBV precore mutants were detected by direct sequencing of amplified PCR products. Thirty-three HBeAg-positive patients (Group 1: wild- type, Group 2: mixed) were received 3-6 MU INF three times a week for 4-6 months. We did follow-ups for at least six months(mean : Group 1-11.3, Group 2- 13.7 months). A complete responder was defined as persistent(>6 months) normalization of transaminase and loss of HBeAg and/or seroconversion. RESULTS: The HBV precore mutants were found in 15 cases(31.2%) among 48 patients: 7 cases(21.2%) in 33 HBeAg-positive patients and 8 cases(53.3%) in 15 HBeAg-negative patients. The HBV precore mutants were more frequently found in HBeAg-negative patients(p= 0.043). Differences in severity of hepatic pathology were not observed in the wild-type versus mutant-type chronic hepatitis B patients(p =1.00). Initial response rate was not significantly different between two Groups(p= 0.228), but complete response rate had a lower tendency in Group 2 (p=0.073). CONCLUSION: There is a tendency for HBV precore mutants to be less responsive to INF therapy than wild type. Therefore the patients with chronic hepatitis B should be treated as early as possible in natural history of their liver disease before the emergence of HBV precore mutants.

The effects of resin on the respiratory health have been investigated in 309 workers from four iron and steel foundries and the results compared with those from 122 workers who were not significantly exposed to resin gas and silica dust at the same industries. Phenol-formaldehyde resin was used in the core making and molding processes and workers were exposed to their decomposition products as well as to silica dist containing particulates The subjects were grouped according to formaldehyde, dust and other gas exposures, and smoking habits were considered also in the analysis. Standardized respiratory symptom questionnaire was administered by trained interviewers. Chest radiograph, pulmonary function tests, and methacholine challenge tests were done. Environmental measurements at the breathing zone were carried out to determine levels of formaldehyde, respirable dust and total dust. Foundry workers had a higher prevalence of symptoms of chronic bronchitis with chronic phlegm and chronic cough when exposed to dust. Exposure to gas was significantly associated with lowered FEV1 and obstructive pulmonary function changes. Exposure to formaldehyde and phenol gas was associated with wheezing symptom among workers, but FEV1 changes after methacholine challenge were not significantly different among different exposure groups. When asthma was defined as the presence of bronchial hyperreactivity with more than 20% decrease in FEV1 after methacholine challenge, 17 workers out of 222 tested had asthma. Fewer asthmatic workers were found among groups exposed to for maldehyde, gas and dust, which indicates a healthy worker effects in a cross-sectional study. The concentration of formaldehyde gas ranged from 0.24 to 0.43 ppm among studied foundries. The authors conclude that fornaldehyde and phenol gas from combust resin is probably the cause of asthmatic symptoms and also a selection force of those with higher bronchial reactivity away from exposures.

Bacillus anthracis, the etiological agent of anthrax, has been taxonomically classified into Bacillus subgroup I with B. cereus, B. mycoides, and B. thuringiensis based on their phenetic and genetic charateristics. Especially, DNA studies indicated that these species were closely related hence these species has been proposed as a single species with four subspecies. There has been controversy about taxonomy of B. anthracis isolates because none of the simple and rapid identification methods are available for closely related taxa so far. In this study, we have used VNTR analysis for reidentification of 7 strains of B. anthracis and 9 strains of closely related species. In the PCR analysis, All of the B. anthracis had a variable region of DNA sequence exception with Youngdungpo. One polymorphisms were found by the presence of four copies with the 12-bp tandem repeat sequences except Kunja. Of the closely related species, the equal size of (VNTR)' was amplified from Bacillus spp. Kyungjoo 3 and B. cereus. The sequences of Kyungjoo 3 was identical with B. anthracis. Whereas the tandem repeat sequences was not found in B. anthracis Kunja and B. cereus. Therefore, B. anthracis Kunja was finally reidentified as a B. cereus. As a results, the analysis of VNTR could be used for rapid identification for B. anthraicis from B. anthracis closely related taxa and molecular epidemiological studies of anthrax.

Brunners gland adenoma is a benign epithelial tumor of the duodenum originating from submucosal Brunners gland. This is an extremely rare entity that account for only 10.6% of benign duodenal tumor, which are themselves relatively rare, representing 0.008% of all surgical and autopsy specimens. The clinical manifestation are nonspecific gastrointestinal complaints, such as bloating or epigastric pain, and the tumor gives rise to melena or anemia, due to the ulceration or erosion of the tumor. The diagnosis is usually made by radiologic studies and gastroduodenal endoscopy which can also provide definitive treatment. The aim of treatment is complete removal of the lesion and exclude malignancy. We report on 4 cases of Brunners gland adenoma which was confirmed by operation or endoscopic polypectomy.
