The purpose of this study was to examine the trends of length of hospital stay (LOS), which is most likely to be a major attribute to hospital performance From 1984 to 1994, an average LOS of each hospital was analyzed by factors such as medical departments, bed size, occupancy rate, region and ownership. This study was analyzed changing rate of LOS during 11 years. This rate was calculated by simple regression, which was used only with hospital without missing data during 11 years. This study findings are as follows. 1. The results indicated that the average LOS was steadily increased until 1990 but it was slightly decreased after 1990. 2. This trend could be found in all hospital scale and all group of occupancy rate. Specifically this trends of LOS were found in internal medicine, corporate owned hospitals, and hospitals in major city. But LOS of individual owned hospital was continuously increased until 1994. 3. Means of changing rates of LOS were calculated from 1984 to 1994. If we divided it into two parts, before 1990 and after 1990, most changing rates of LOS before 1990 except individual owned hospital were found positive sign. The changing rates after 1990 were negative sign but small hospital(lesser then 200 bed), individual owned hospital, national & public hospital and hospital in small urban have little change of LOS after 1990. Finally from this results we thought that most hospitals in korea began to be concerned with LOS. Nevertheless LOS of several hospital such as small hospital or individual owned hospital was increased. And this trend may be caused by a few patients, low occupancy rate, or low profit. This trend of LOS is different from that of other countries. Perhaps this phenomenon is resulted from the reimbursement method. Because of fee for service reimbursement system in korea the hospitals didn't need to shorten LOS in order to save the cost and increase the profit. Therefore reform of hospital cost reimbursement method will be reduced to reduce hospital cost in korea. we thought that the korean health authority should consider the reimbursement method by unit of bundle of services, for example DRG and prepayment in the united states. This study presents some limitations such as on insight of severity of disease, case-mix measurement of hospital, and other clinical characteristics that can possibly affect LOS, However, this study reports an important trend in LOS from 1984 to 1994.

Korean Journal of Dermatology 1987;25(2):222-233
A clinical observation of cutaneous complications was made on 200 patients receiving cancer chemotherapy at the Department of Internal Medicine, Seoul National University from January through May, 1986. The results were as follows: 1. Among the 200 patients, 191 case(95. 5%) showed cutaneous complications 2. The cutaneous complications included the following; hyperpigmentation(14l cases, 70. 5%), alopecia(138 cases, 69.4%), nail change(118 cases, 59.0%), mucositis(47 cases, 23.5%), dryness of the skin(40 cases, 20.0%), seborrheic dermatitis(24 cases, 12. 2%), increase of seborrheic keratosis(11 cases, 5.6%), folliculitis or acneiform eruptions(9 cases, 4,5%), melasma(6 cases, 3.0%), gynecomastia(3 cases, 1.5%), vessel hardening or dimpling(3 cases, 1.5%), radiation recall(2 cases, 1.0%), hyperhydrosis(2 cases), photosensitivity(1 case, 0.5%), tissue necrosis(1 case), facial flushing(1 case), purpura(1 case) and obesity(1 case), 3 Steps were taken to determine the chemotherapeutic agents causing these cutaneous complications, though in some cases it was difficult in determining exaetlr which chemotherapeutic agent was the cause of the observed cutaneous complication.

A clinical observation of the nail pigmentation change was made on 200 patients receiving cancer chemotheray who were seen at; the Department of Internal Medicine, Seoul National University Hospital, from January through May, 1986. The results were as follows: l. Among the 200 patients, 118 cases(59%,) showed nail pigmentation changes. 2. The patterns of nail pigmentation change were as follows: Parallel transverse band(70 cases 59.3%), longitudinal pigmentated band(32 cases, 27. 1%), brown arc(25 cases, 21. 2%), Proximal black pigmentation(10 cases, 8. 5%), diffuse pigmentation(5 cases, 4.2%), parallel transverse white line(5 cases, 4.2%), half and half nail(3 cases, 2. 5%), pigmentations with transverse white band(1 case, 0. 8%). 3. Various cambinations of nail pigmentation pattern were found in 33 patients (28. 0%). 4. 11 cases of the nail dystrophy with nail pigmentation change were observed: Longitudinal ridge(7 cases), transverse groove(3 cases), wavy transverse fissure (1 case).

We report a case of morphea profunda in a 21-year-old male who had diffuse brown sclerotic plaques on his extremities. Laboratory findings showed peripheral eosinophilia and an increased titers for anti-DNA and anti-nuclear antibodies. Histopathologic findings showed diffuse fibrosis and a thickening of the lower dermis and subcutaneous tissue. He has been treated with hydroxychloroquine 400mg per day and the sclerosis of the skin improved.

Korean Journal of Dermatology 1987;25(4):543-545
Adenoma of the nipple is a benign tumor of the lactiferous ducts of the nipple which frequently causes erosion of the surface. It can clinically mmic Paget's disease and histologically be misdiagnosed as a well-differentiated adenocarcinoma. A 20-year-old woman developed an erythematous oozing patch on the right nipple two years ago, which subsequently developed iiito verrucous surfaccd papules. A biopsy specimen of the lesion showed focal acanthosis of the epidermis. The tumor was composed of fairly well-circumscribed, glandlike structures within the nipple stroma. Ductlike struciures, papillary areas, solid nests of cells and cysts lined by squarnous epithelium, could be seen, Two cell types lining the ducts were recognized; inner columnar cells and peripherally located cuboidal cells. Although simple excision of the adenoma is the treatment of choice, our case was treated successfully by electrucoagulation.

Xanthoma disseminatum (XD) is one of cutaneous nonhistiocytosis X, and characterized by multiple, widely distributed red, brown, yellowish papules and nodules that tend to coalesce. We present a case of XD with characteristic clinical findings and treated with the combination therapy of COz laser vaporization and high dose steroid.
