In spite of vigorous efforts to enhance appropriateness of blood usage in surgery, it is recognized that there are still not a few overuse and misuse of blood products in Korean hospitals. To assure appropriate use of blood, continuous monitoring and controlfling blood orders, particularly for surgical operations, should be implemented. The indicator of 'ratio of crossmatching to transfusion' (C/T ratio) has been focalized on in this regard. The authors investigated C/T ratio for eight hospitals, evenly distributed in their geographical location as well as size. Only elective surgeries operated from March 1 to May 31, 1995 were included for analysis. Standardized survey format was distributed, and retrospective reviews of medical records were performed by volunteer surveyors from each hospital after two sessions of pre- survey education. The results were as follows. Average C/T ratio, for all hospitals and all surgeries, was 1.76. Differences in C/T ratio by sex, months, clinical departments, blood components were not significant. However, the ratio showed increasing tendency with ages. The C/T ratio on the average was not higher, compared with the recommended guideline. However, due to study' s limitations ini standardization of survey method and verification of data, we could not conclude that current status of appropriateness of blood use is satisfactory. In addition, to pervasively use the C/T ratio as a quality indicator for blood use management, supplementary measures, such as standardization of data, should be adopted.

This study was conducted to assess macro- and micronutrient compositions in school lunch menus based on the 'Dietary Guideline' for School Lunches. Ninety-five dieticians in elementary school in Chungbuk were asked to complete a questionnaire on characteristics of the school lunch program (such as type of foodservice, food production system), the information about dietitians (such as age, education, and job history), and the extent of the use of processed foods and frozen foods. They were asked to return the questionnaire with the menus including the name and the quantity of every food ingredient offered during a week. A total of 554 lunch menus provided for a week of June 2004 were analyzed. Average nutrient content per meal was as follows; 660 kcal, energy; 92.9 g, carbohydrate; 26.7 g, protein; 21.1 g, fat; 287 microgramRE, vitamin A; 0.5 mg, thiamin; 0.5 mg, riboflavin; 29.3 mg, vitamin C; 338.2 mg, calcium; 3.9 mg, iron; and 97 mg, cholesterol. Average percentages of energy from carbohydrate, protein and fat was 56.2%, 16.2%, and 29.0%, respectively. The mean nutrient content per meal was higher in rural-type than in urban-type schools. The weekly menu of 40% of the schools provided < 55% of energy from carbohydrate, and 39% of the schools offered lunch that provided > or =30% of energy from fat. The micronutrient content was generally high when the percent energy from fat was less than 25%. Our results showed that only 52.6% of the schools provided lunches with the energy composition as in the 'Dietary Guideline' of School Lunches. Whole Milk was the major contributor to fat, saturated fatty acid and cholesterol. We suggest that school foodservices start to provide low fat milk instead of whole milk to reduce fat, saturated fatty acid and cholesterol. If low fat milk is served instead of whole milk, percentage of energy from fat and saturated fat can be reduced from 29% to 25%, and from 10.2% to 9.1%, respectively, and cholesterol could be reduced from 97 mg to 79 mg. Efforts to meet 'Dietary Guideline' for School Lunches should be made, especially to reduce fat intake, while maintaining essential nutrient intake at sufficient levels for children.

BACKGROUND: It is a popular notion that cutaneous ageing includes two distinct phenomenon; true ageing, a universal presumably inevitable change attributable to the passage of time alone, and photoageing, changes attributable to chronic habitual sun exposure that are neither universal nor inevitable. Numerous investigations with experimental animals, in vitro skin models have been conducted, although, few histological studies to date have attempted to announce fundamental morphological changes with innate ageing. OBJECTIVE: We compared skin derived from the breast of old and young persons using light microscopy to discern structural changes in epidermal and dermal morphology with advancing age. METHODS: The histological, immunohistochemical studies were performed with normal skin sections of thirty donors who were diagnosed with breast cancer. They were classified into three age cohort groups; nine into group I (22 to 38), twelve into group II(40 to 52), and nine into group III(54 to 87). We chose the breast as an area that might closely resemble intrinsically aged skin. This region is relatively shielded from photoageing by its anatomical location. Analysis of data was performed using the Kruskal-Wallis and ANOVA test for dermal parameters based on a 5-point rating scale, and a simple regression test for a positive rate of immunoreactants. Results : 1. Light microscopic appearance of aged skin revealed a more flattened epidermis than young skin. There was no trend for an increase in epidermal melanin content per unit area on Fontana-Masson staining. There was an age-associated decrease in the Ki-67 positive rate(p<0.001), the density of Ki-67 positive cells declined approximately 1.16% per decade in photoprotected skin(p<0.001). The number of S-100 positive cells declined approximately 4.4/mm width along the dermo-epidermal juction per decade in photoprotected skin(p<0.001). The expression of differentiation markers(keratin 1, involucrin, filaggrin, loricrin) were not different among the three age cohort groups. 2. With advancing age, there was an attenuation in the number and diameter of elastic fibers in the papillary dermis and an increase in the number and straightness of the same fibers in the reticular dermis. The collagen fibers are arranged in sparse bundles in disarray, and/or aggregates of loosely woven, straight fibers in the aged skin. There was an apparent, age-related decrease in the stainability of ground substances in the papillary dermis on colloidal iron staining. Conclusions : Our data documents semi-quantitative differences among three groups in intrinsically aged breast skin and provide the framework for future research to evaluate the ageing process.

PURPOSE: To estimate the prevalence of periodontitis in Korean adults and to examine the associations between periodontitis and known risk factors. METHODS: Using Korean National Oral Health Survey 2006 data, a total of 4,263 people who had taken oral examination, interviewed by questionnaire, and aged 18 or older were sampled. The prevalence of periodontitis measured by Community Periodontal Index (CPI) was calculated and the differences in prevalence according to known risk factors (age, sex, monthly income, education, residential area, tooth-brushing frequency, regular dental visit, smoking, and diabetes) were examined with chi-square test. Logistic regression analysis was performed to see the effects of each risk factor on the risk of having periodontitis. All statistical approaches were reflected national sampling design using Survey procedures in SAS 9.1. RESULTS: The overall prevalence of periodontitis in Korean adults was 10.3%. There existed statistically significant differences in crude prevalence for periodontitis according to the all risk factors. In logistic regression, older age groups (O.R.:2.94-3.71), people living in rural area (O.R.:1.87), and current smokers (O.R.:1.77) were significantly prone to have periodontitis. People who earned monthly income of more than 2 million Korean won (O.R.:0.64) and brushed their teeth two or more times per day (O.R.:0.60-0.62) had significantly lower risk of having periodontitis. CONCLUSIONS: About 10% of Korean adults had periodontitis in 2006. People who were older, living in rural region, in lower income status, smoking, less tooth brushing were more likely to have periodontitis.

BACKGROUND: Neurofibiomat,osis type 1(NF-1) is a multisystemic disorder of genetic ori gin, affecting one in every 3000 to 4000 people. It is clinically important in the aspect of dermatology, pediatrics, orthopedic surgery, neurology, neurosurgery and ophthalmology. OBJECTIVE: The purpore of this study was to elucidate the clinical characteristics of NF-1 in Korean people. METHODS: We carried out a retrospective study on 112 patients which were compatible to the diagnostic criteria of Riccardi and Neurofibromatosis Conference Statement. The results were compared with other western studies. RESULTS: The age of onset, sex ratio, family history of neurofibromatosis, and clinica features of cafe-au-lait spot, neurofibroma, and axillary freckinings did not differed from western countries. However, some characterist,ics of NF 1(e.g. Lisch nodule) were not as sessed in the most of the cases and incomplete evaluations of the systemic diseases wen found. CONCLUSION: In this study t.he clinial features of NF-1 did not differ from western coun tries in many aspects. A more intensive evaluation of patient,s status is needed to manag; NF-1 patients appropritely.

Peritoneal mesothelioma is a rare disease which arises from the mesothelial lining cells in the peritoneum and spreads to the peritoneal wall, omentum and other abdomina1 organs. Aabestos is one etiologic factor and the other factors are genetic cause, radiation, exposure to toxic materials and recurrent yeritonitis. We experienced a case of multiple small nodular peritoneal mesothelioma after exposure to asbestos for over 20 years. He was a sailor and had worked in the engine department of the ship, in which he wrapped up the pipe of engine in asbestos. This person came to our hospital because of inconvenience due to a distended abdomen. Tumor markers were all within normal limits and there was no evidence of tuberculosis in the abdomen and chest. The CT findings of the abdomen were as follows: There was abundant ascites in the abdominal cavity and multiple small nodules on the parietal peritoneum and especially on the lower abdomen. The omentum thickened diffusely. It was difficult to distinguish from peritoneal mesothelioma and peritoneal carcinomatosis or intestinal tuberculosis. The laparoscopic findings were as follows: There were multiple small nodules on the parietal peritoneum and omentum. The small nodules were a gray white color and uneven compared to tuberculous peritonitis. Therefore, we observed the malignant mesothelial cells by means of the light microscope and electron microscope and concluded that this case was peritoneal mesothelioma.
