Intramuscular lipomas are benign soft-tissue mesenchymal tumors which rarely occur in the region of the head. These tumors present as slow-growing, generally painless masses and are easily misdiagnosed initially as epidermal inclusion cysts. We describe a 44-year-old woman who presented with an intramuscular lipoma of the frontalis muscle.

Journal of the Korean Dietetic Association 2007;13(2):169-182
We investigated elementary school students' knowledge, behavior, experience and preference of education method related to food safety in order to provide basic information for food safety educational program. A survey study was conducted with 569, fourth and sixth grade students, from two schools in Seoul and Ulsan. Students were asked thirty-two questions regarding food safety knowledge, behavior and experiences as well as their attitude to food safety class and preference for teaching method. The data was analyzed for the frequency analysis, t-test, chi-square test, one-way ANOVA and Pearson correlation using the SPSS/Windows. Results indicated that 91.9 percent of the respondents did not know what unsanitary food is. 67 percent of the respondents did not know the proper method of hand washing. Although the students' level of knowledge and behavior associated with food safety was low, there was meaningful correlation(r =.184, p<.01) between knowledge and behavior. Surprisingly, students in higher grade did not demonstrate an exceeding food safety knowledge and behavior. More than 50 percent of the subjects did not have food safety education either at home or school. 60 percent of the respondents interested in food safety and the majority recognized that a food safety education is needed. Students want to learn about unsanitary food(34.1%), foodborne illness(29.7%), food selection and storage method(21.3%), and personal hygiene(11.2%) through game, role play, and practice in real situation. These results suggest that development of food safety education program is needed through the elementary school year and the education program must include fun activities in which students can participate.

PURPOSE: To evaluate the long-term effectiveness of different surgical procedures according to horizontal eyelid laxity in correcting involutional entropion. METHODS: This retrospective study reviewed 104 eyes of 79 patients with involutional lower eyelid entropion who underwent surgical repair. The 62 eyes with horizontal eyelid laxity were classified as group I. In 17 eyes of group I, we performed the lateral tarsal strip procedure alone (group Ia), while in 45 eyes of group I, we performed the lateral tarsal procedure and Quickert suture (group Ib). The 42 eyes without horizontal eyelid laxity were classified as group II. In 13 eyes of group II, we performed a lower eyelid retractor reinsertion procedure only (group IIa), and in 29 eyes of group II, we performed combined lower eyelid retractor reinsertion and orbicularis resection (group IIb). RESULTS: The recurrence rate in these four surgical subsets (group Ia , group Ib, group IIa, group IIb) was 11.7%, 0%, 15.4%, and 6.9%, respectively, with an average follow-up of 11 months. Six recurrent eyelids and two overcorrected eyelids successfully underwent procedures to correct recurrent entropion and ectropion, respectively. CONCLUSIONS: The lateral tarsal strip procedure is an effective approach for achieving long-lasting correction of involutional entropion with horizontal eyelid laxity, whereas the lower eyelid retractor reinsertion procedure is an effective approach for achieving long-lasting correction for involutional entropion without horizontal eyelid laxity. Use of the Quickert suture reduced the need to repeat the lateral tarsal strip procedure and additional orbicularis resection decreased the need to repeat the lower eyelid retractor reinsertion procedure.

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.

Cardiovascular changes induced by a variety of physiological, surgical or emotional stresses are associated with increased sympathetic nervous system activtity. Sympathetic stimulation lowers the ventricular resistance in patients with ischemic heart disease. Thus sympathoadrenal aetivation may play role in sudden cardiac death. We measured the catecholamine levels just before and after fiberoptic gastroscopy, The results were as follows: 1) Though there was no statistical significance, plama catecholamine levels tends to increase during and after fiberoptic gastroscopy. 2) Significant changes in mean blood pressure did not occur during and after fiberoptic gastroscopy. 3) Before fiberoptic gastroscopy, norepinephrine level of three hypertensive patients were lower than the levels of studied patients, But during and after fiberoptic gastroacopy, norepinephrine level increased by 3 times. 4) The highest norepinephrine level was 847 pg/ml and epinephrine level was 110 pg/ml. Though sympathetic response was enhanced by fiberoptic gastroscopy, norepinephrine level did not increase up to the level shown in myocardial infarction or severe exercise.

This study was undertaken to investigate the characterization and distribution patterns of MHC class II positive dendritic cells[DCs] and ED2 positive tissue macrophages throughout the estrous cycle and during pregnancy in the rat ovary. The immunohistochemical characterization of the cells was carried out using the monoclonal antibodies OX6 and ED2 in cryostat-cut sections. DCs were distributed in the theca cell layer of the growing and mature follicles,stroma and corpus luteum. Tissue macrophages were distributed in the theca externa of the growing and mature follicles, stroma and corpus luteum but they were smaller in number than DCs. None of DC and tissue macrophage was found in the ovum, granulosa layer and follicular cavity of the ovarian follicle. However, DCs and tissue macrophages were present in the granulosa layer and follicular cavity in the atretic follicles. Degenerating corpus luteum contained a vast number of OX6 positive cells. On the contrary, fewer tissue macrophages were founcl in the degenerating corpus luteum. More macrophages tended to be observed in the former follicular cavity and theca lutein cell layer than in the granulosa lutein cell layer of the corpus luteum. In stroma,DCs and tissue macrophages were more frequently found around the blood vessels than in the other region, however, DCs were relatively greater in number than tissue macrophages. There was no estrous cycle and pregnancy dependent variation in the numbers and distribution patterns of DCs and tissue macrophages. In conclusion, the rat ovary contains rich networks of MHC class II positive dendritic cells and ED2 positive tissue macrophages. These findings suggest the existence of a well-developed system of immunological surveillance in the rat ovary. The results of this study have potentially important implications for the understanding not only of the ovarian immune system and the pathogenesis of various ovarian diseases but also of various physiologic functions of the ovary.
