In September 1998, a case of nosocomial cutaneous myiasis caused by Lucilia sericata (Meigen, 1826) in a 77-year-old male was found. The patient had been receiving partial maxillectomy due to the presence of malignant tumor on premaxilla. This is the first verified case involving Lucilia sericata in Taegu, Korea. In the present paper, the salient morphological features of the third instar larvae involved have been studied.

The aim of this study was to assess the degree of association between individual stress and the amount of smoking among male senior students of a medical college. The questionnaire survey was conducted twice for collecting the data on stress level in terms of BEPSl score, smoking amounts, alcohol intake, and residence type in 1992 and 1993. Among the 223 responders, 39.9% were smokers. In the smokers, the association between stress level and smoking amount was significant after controlling for alcohol intake and residence type (P < 0.l). Especially in the group of living without family, the association was more significant (p=0.06). Therefore, it is recommendable that the stress management program is called upon for the student smokers to reduce smoking amount.

Teratomas are neoplasm composed of a wide variety of tissues foreign to the organs or anatomic sites in which they arise. They generally arise in gonads but a few cases are described in extragonadal sites, such as sacro-coccygeal region, mediastinum, neck, and retroperitoneum. Most sacrococcygeal teratomas are encountered in infants, particularly in neonates, and a primary sacrococcygeal teratoma is a extremely rare neoplasm in adults. Recently, we experienced two cases of presacral teratomas arising in adult, therefore we present these cases with a brief review of the literatures

The purpose of this study was to investigate utilization and storage management practice of the frozen and refrigerated foods in school foodservice. 222 dietitians employed in school foodservice were surveyed. In school foodservice, the refrigerated stock farm products and seafoods (78.3%) were more used rather than frozen products (47.5%). According to school foodservice characteristics, the refrigerated meats including dairy products were more frequently used in elementary and middle schools than high school foodservice. On the other hand, the foodservice in high school used more frozen seafoods and processed foods than elementary school did. The data also showed a tendency for the contracted foodservice using more frozen meats and seafoods rather than refrigerated products when comparing with the self-operated foodservice. In terms of receiving conditions, storage methods and storage time, the result indicated that frozen or refrigerated products were often delivered at inappropriate temperature. Especially some products which were needed to be shipped and stored at refrigerated temperature such as mollusks, were delivered and kept at room temperature. The most frequently used thawing method were running water (56.9%), however, the frozen products were often sitted at room temperature for the purpose of thawing. According to the results, several inappropriate handling processes for frozen and refrigerated products were found in school foodservice. In order to improve handling process for frozen and refrigerated products, recognition of food handlers' weakness about storage and distribution, development of radical standards for receiving conditions, storage and thawing methods should be debated.

PURPOSE: This study was conducted to examine prerequisite-program performance of the hospital foodservice operation and develop measures for improvement of prerequisite-program performance. METHODS: Data were collected through surveys administered to 168 hospital dieticians in the Seoul, Incheon, Gyeonggi-do, Daegu, and North Gyeongsang areas. Out of total questionnaires, 65 questionnaires were usable and the response rate was 38.7%. Statistical analyses were performed using the SPSS program (ver 20.0) for chi2-test and one-way ANOVA. RESULTS: According to the result of the prerequisite-program evaluation, the percentage of 'appropriate', 'needs to be improved', and 'inappropriate' was 44.6%, 47.7%, and 7.7%, respectively. The score for the 'inappropriate' group was significantly lower than that of the 'appropriate' group or 'needs to be improved' group on the food safety management (p < 0.001), preparation facility management (p < 0.001), water management (p < 0.001), and storage.transportation management (p < 0.05) parts. Holding rate of foodservice facility and equipments in the 'appropriate' group were significantly higher than in the others on convection oven (p < 0.01), air conditioner (p < 0.01), three-compartment sink (p < 0.01), hot-holding equipment (p < 0.01), cold-holding equipment (p < 0.05), exclusive thawing refrigerator (p < 0.05), and sterilizer for sanitary shoes (p < 0.05) items. CONCLUSION: To improve the quality of hospital foodservice, foodservice managers and HACCP specialists should develop and implement a prerequisite-program and a HACCP plan considering the characteristics of the hospital foodservice operation.

BACKGROUND: Korean people could abuse healthy foods as well as medications, which might cause serious side effects. The aim of this study was elucidating liver dysfunction due to the self-medications of hepatotonics, healthy foods and herb medications by nested case-control study. METHODS: Study subjects were drawn from male members of seoul Cohort Study who were recruited by self-administered structured questionnaire survey through mailing to the healthy men between the age of 40 and 59 years through the program of biennial health check-up offered by Korea Medical Insurance Corporation(KMIC). The liver dysfunction was defined as the level of serum AST and ALT above 40 IU/L and increased in more than one hundred per-cent during the 2 year follow-up period. To estimate the odds ratio between self-medication and liver dysfunction after controlling for potential confounders, logistic regression was performed. RESULTS: During the follow-up period, 30 members were identified to fit into case criteria and 2,625 members were selected as control. In logistic regression analyses, history of healthy foods intake, age under 45 years, obesity, and habit of regular exercise were significantly associated with liver dysfunction. The following factors exhibited no statistical significance: intake of hepatotonics, of herb medicine; history of disease in family, of operation, and of radiologic examination; smoking habits and drinking amounts. CONCLUSION: The significant association between the intake of healthy foods and the liver dysfunction illustrates that chronically optional overuse of healthy foods might bring to hazards to health. As the increasing trend of the size of purchasing healthy foods in Korea, pharmacoepidemiologic studies evaluating the safety and efficacy of the widely used healthy foods should be performed in the near future.

STUDY DESIGN: A retrospective study. OBJECTIVE: To compare the peri-operative morbidity of patients who undergo same-day operations for lumbar spinal stenosis accompanied by severe osteoarthritis of knee with those who undergo staged operations . SUMMARY AND LITERATURE REVIEW: There is no report on the peri-operative morbidity of same-day operations for patients who have a concurrent lumbar spinal stenosis and severe osteoarthritis of the knee, even though elective surgery for lumbar spinal stenosis or total knee arthroplasty are safe procedures. MATERIALS AND METHODS: From January 1996 to December 2005, 11 patients who underwent staged operations for lumbar spinal stenosis and concomitant osteoarthritis of the knee (Group I) and 14 patients who underwent total knee arthroplasty and lumbar spinal decompression and fusion on the same-day (Group II) were compared in terms of the operative time, blood loss, perioperative complications and admission days. The data was analyzed statistically using a chi-square test through SPSS v.10.0. RESULTS: The mean surgery time in groups I and II was 266+/-34.4 minutes and 258+/-54.2 minutes, respectively. The estimated blood loss during operation of groups I and II was 1055+/-229.6 and 925+/-174.0. There was no statistical differences between the two groups. There were no life-threatening complications in any group. The admission period for group I and group II were 41.0+/-6.05 days and 30.1+/-5.10 days respectively, but there was no statistical significance. CONCLUSION: There was no difference in the surgical time, estimated blood loss, and complications between the group that underwent the staged operations and the group that underwent same-day operations. A possible surgical option is to perform both procedures on the same day.
