1.Epidemiological Trend of Japanese Encephalitis in Korea.
Korean Journal of Preventive Medicine 1987;20(1):137-146
The following facts have been identified as a result of epidemiogical trend and characteristic of Japanese Encephalitis in Korea for the last 20 years. First: The Epidemiological period which was ten-year and three-year in the past has been disappeared following the start of immunization program at 1970. Second: The incidence rate was much higher in the south and West areas than northeast area of Korea. City and province with the highest incidence rate was Chungcheong Nam Province and Cholla Buk Province. Third: Regardless of scope of prevalence, the main season that 90 percent of total incidence occurs in one month from mid-September. Fourth: The number of case by age was that 80 percent of total patients is children aged 3-15. Recently there is an increase in the number of patients who are elderly people. Fifth: The study on the ecological conditions of mosquito including wintering and effectiveness of immunization for Japanese Encephalitis and duration on antibody should be done. Sixth: There has been no case of Japanese Encephalitis during last three years since 1984 mainly due to disinfecting to eradicate mosquitos, immunization for vulnerable group of people aged 3-15, individual precaution not to be bitten by mosquito, improvement sanitation. While there has been no case of Japanese Encephalitis during last three years, there is possibility that Japanese Encephalitis becomes prevalent again anytime since its virus has been isolated continuously from the natural reservoirs.

3.Study of the Amount and Share of Drug Cost in the Total Medical Fee under Medical Insurance Scheme.
Korean Journal of Preventive Medicine 1989;22(2):223-235
To grasp the idea about how drugs are used under Medical Insurance Scheme, the amount and share of drug cost in the total medical fee have been reviewed and analyzed for different types of patients(in-patient out-patient), medical institutions and frequently seen diseases and following findings were revealed. In 1986, drug cost took 32.78% of total medical fee for in-patients and 32.98% for out-patients averaged over 30% share as a whole. When drug cost per case in 1980 be indexed to 100, it has shown steady growth to become 200 for in-patients and about 150 for out-patients in 1986. The contribution of drug cost to the total medical fee is, regardless of patient type-in-patients and out-patients, the highest in University hospitals and followed by General hospitals, Hospitals and Clinics in descending order. That for the most frequent 10 diseases came out the highest, 79% with the essential benign hypertension of out-patients in the General hospitals, 61% for the gastric ulcer of out-patients in Hospitals and 33% for the female genital disease of out-patient in Clinics. The drug cost of oral formula was contributed the most, 7.93% by cardiovascular agents followed by hepatic detoxicants(5.47%) and out-patients(4.93%), and that of injectable formula was contributed the most by antibiotics(24.17%), followed by protein amino-acid preparations(6.19%). The order of drug usage by specially for the in-patients was the highest with internal medicine followed by general surgery and E.N.T, and that for the out-patients was in the order of Internal medicine, neuropsychology and Ob/Gy. This study revealed that the drug dependency was characteristically different to specialty. In view of the fact that drug cost on average exceeds over 30% of total medical fee, proper drug administration appears to be vitally important for the financial standing of the Medical Insurance Scheme. As a consequence, drug usage guidelines including antibiotics usage shall be established first of all and the voluntary participation for the regulation of drug usage and propagation of the guidelines to medical institutions are strongly coerced.

We report a case of acute graft-versus-host disease, which developed after bone marrow transplantation because of acute myelocytic leukemia in a 39-year old male, The pruritic, erythematous maculopapular eruptions began to developed on the perioral regions, and spreaded the face, the oral mucosa, both hands, and buttocks at the twenty fourth day after bone marrow transplanta.tion. The eruptions were confluent to form erythematous patches. Iistopathological findings show parakeratosis, lymphoid cell exocytosis, and papillary edema, lymphohistiocytic infiltration, and melanophage in the upper dermis, and basal vacuolation. He was treated systemically by methylprednisolone, and antilymphocytic globulin, and tapically by emollients and steroids.

BACKGROUND: Increasing evidence supports an association between age-related loss of muscle mass and insulin resistance. However, the association has not been fully investigated in the general population. Thus, we investigated the association between appendicular skeletal muscle mass (ASM) and insulin resistance in an elderly Korean population. METHODS: This cross-sectional study included 158 men (mean age, 71.8) and 241 women (mean age, 70.6) from the Korean Social Life, Health and Aging Project, which started in 2011. In this study, ASM was measured by bioelectrical impedance analysis and was analyzed in three forms: ASM (kg), ASM/height2 (kg/m2), and ASM/weight (%). The homeostasis model assessment of insulin resistance (HOMA-IR) was used as a measure of insulin resistance. The relationships between the ASM values and the HOMA-IR were investigated by multiple linear regression models. RESULTS: The HOMA-IR was positively associated with ASM (beta=0.43, P<0.0001) and ASM/height2 (beta=0.36, P<0.0001) when adjusted for sex and age. However, after additional adjustment for body weight, HOMA-IR was inversely associated with ASM (beta=-0.43, P<0.001) and ASM/height2 (beta=-0.30, P=0.001). Adjustment for other potential confounders did not change these associations. Conversely, HOMA-IR was consistently and inversely associated with ASM/weight before and after adjustment for other potential confounders. CONCLUSION: Our results support the idea that lower skeletal muscle mass is independently associated with insulin resistance in older adults. When evaluating sarcopenia or muscle-related conditions in older adults, their whole body sizes also need to be considered.

Angiodysplasia is a vascular lesion of the gut, which reveals intestinal bleeding as a major symptom. It is the cause of as much as 5~6% of the intestinal bleeding of unkown origin. Pathologically, it reveals anomalous submucosal vascular overgrowth, which is characterized by tortuous, dilated and thin-walled vessels. Because the lesion is mainly submucosal. It is hard to diagnosis with endoscopy and even in laparotpmy. Angiography has a low detection rate for angiodysplasia, but some of this typical findings are delayed excretion of dye into the venous structure around the lesion, vascular tuft in the arterial phase, and accelerated dye secretion into venous structure in the situation of arteriovenous malformation. Endoscopy, especially colonoscopy is so effective a diagnostic method as to make interventional therapy. Conjugated estrogen therapy is effective and is regarded as choice of treatment in the not-life-threatening intestinal bleeding caused by angiodysplasia. Surgery is only indicated in the case of uncontrolled bleeding. Intestinal obstruction has rarely been reported as another manifestation of intestinal angiodysplasia. Therefore pathologic definition should be confirmed, and research for pathophysiology of mucosal hypertrophy in the angiodysplasia is needed.

Chronic postirradiation changes of skin reflect the injury of dermal structures particularly the vasculature and connective tissue. The clinical signs include atrophy, partial or complete destruc tion of cutaneous appendatges, telangiectasis, sclerosis of underlying tissue, pigrnentary changes, and in rare instances, ulceration with or without var ious premalignant and malignant neoplasms. The patient, was a 65-year-old man, who had been exposed to a large amount. of X-ray irradi- ation on his hands incidentally or accidentally for a long time. The skin changes of his hand were thickening and hardening of all digits loss or focal consttict,ion of digits, and keratotic papules. Epidermal hyperplasia and fibrous thickening of collagen bundles were found on skin biopsy. Gradual narrowingal of the bony caliber with eventual resorption was noticed on radiologic examination. It has been rarely reported in the literature that chronic radiation dermatitis develops severe and unusal manifestions such as acrosclerosis and loss of digit due to osteoradionecrosis.
