Juvenile xanthogranuloma is characterized by one, or oftener many, yellow, re3dish yellow, or, brown 4-to-20 mm papules or nodules on the face, scalp, trunk, and mostly, extensor surfaces. It may involve internal organ besides the skin such as eye, gastrointestinal and genitourinary tracts. anthogranuloma in adult is usually solitary and dose not involve organs other than skin, and generally dose ncit resolve without treatment. Histopathologically, characteristic Touton giant cells usually appear numerously. We report a case of juvenile xanthogranulorna which occured on scalp of 49 year-old male showing typical clinical and histopathological findings.

Cavernous sinus thrombophlebitis may occur as a complication of infectious and noninfectious processes. Septic thrombosis of the cavernous sinuses is a serious life threatening condition, and most commonly follows midfacial skin infections due to Staphylococcus aureus. Isolated sphenoid sinusitis is a rare and elusive clinical problem, and it is an uncommon cause of cavernous sinus thrombosis. We report a case of cavernous sinus thrombophlebitis of spheoid sinusitis origin. A good result has been achieved with immediate medical measures and surgical drainage.

In order to investigate psychological and behavioral characteristics homosexuals and to present evidence that homosexuals are in danger of HIV infection in Korea, this study was done by self-administered questionnaire and then direct interview with the 28(35%) HIV infected homosexual/bisexuals of 79 HIV infected persons reported in 1992. Homosexuals without heterosexual activity were 9 and the others were bisexuals. Sixty-five percent of respondents had a guilty conscience for their homosexual activity. Twenty(71%) were in twenties and 5(18%) in thirties. Twelve(43%) were detected via health card checking by health office, 21% by blood donation, 18% by hospital visit, and 7% by partner notification. Motivations for homosexual activity were curiosity(36%), temptation or recommendation(14%) and compulsion(11%). Eighteen(72%) never used condom on anal sex. Nine of 26 respondents had experience for anal sex with foreigners. Fourteen(54%) of 26 respondents had history for sexually transmitted diseases. Fightly percent did not have sexual contact after HIV infection and the others usually used condom. It was confirmed that over 57% of the respondents were infected within 1 year before HIV diagnosis and over 82% within 2 years. These data suggest that HIV infection among homosexual group is rapidly spreading.

BACKGROUND: After the World-Wide-Web(www) appeared, history has abruptly fallen in the new era of the Internet. In Korea, after the first medical internet site appeared, there was a major development in the WWW. But the quality and quantity of the web-page remains in infancy. Therefore, through the analysis of the Korean medical internet sites on present status, directions for development of Korean medical internet sites can be made. METHODS: From April 1st, 1999 to June 30th, 1999 in the Korean web sites, we visited 1044 sites. They included "Medmark Korea" representing medical search engine, "Eulji medical library" in the Eulji Medical College Hospital, and the medical sites of the "Yahoo Korea", "naver.com", and "simmani.com". Through this internet search, the information about locations, first publication year, classification by characteristics of homepage, speciality, web service form was obtained. Among these sites, acquireing from insufficient source further, questions were sent to the webmasters of 143 websites by e-mail. The questions included 7 items on the characteristic of webmasters, 8 items on the general characteristics of internet sites, 8 items on the contents, and their own comments. RESULTS: The occupation of webmasters was as follows: were physicians 94.4%, were male. According to age distribution, those in their thirties was 48.2%, and forties, 33.3%. Amone the 521 websites confirmed, there were 44 sites in 199 151 in 1996, 237 in 1997, and 79 in 1999. According to the distribution of location, metropolitan areas including Seoul, Inchon, Kyonggi occupied 68.9% among total. The main portion of the intentional visitors was ordinary people comprising 39.2%, members 9.8%, and physicians 7.7%. Concerning the purposes of publication, 38.7% of websites intended for health education to citizens, 31.0% for publicity of hospital or organizations, and 15.5% for exchange of information between members. For the most significant contents, 26.6% focused on the common-sense health issues, 35.7% on exchange of special medical information, 8.4% on education data for medical students, and 13.3% on publicity of hospitals. For the update interval, 22.0% renewed their sites within 1 week, 22.7% in 1 month, 23.4% in 3 months, and 20.6% in 6 months. For the effectiveness of homepage, the rate of `good' and `very good' response was 52.8%. CONCLUSION: Our investigation, showed that medical internet sites are lead by those in their thirties and forties. Web sites was concentrated to metropolitan areas where informational infrastructure was well developed. It is emphasized that efforts to informationalization by are needed by, governmental medical database systems should be established, and that the guidelines which enables validity of medical information should be set forth.

BACKGROUND: To explore an interaction(s) of endothelin with other blood pressure regulating systems, effects of either a high concentration of sodium chloride vehicle or pretreatment with atrial natriuretic peptide (ANP) on the pressor response to endothelin were investigated in rats. METHOD: Sprague-Dawley rats were anesthetized with thiopental (50mg/kg, IP) and were cannulated into left lateral cerebral ventricle. The left femoral artery and vein were also catheterized to measure blood pressure and to serve as an infusion route, respectively. Endothelin (10pmol) dissolved in either normal (0.15M) or high concentration (3.0M) of NaCl vehicle with ANP (1 nmol, ICV). For intravenous (IV) infusion, endothelin(1pmol/min) dissolved either in normal or high concentration of NaCl vehicle was infused for 20min. RESULT: ICV endothelin caused an increase of arterial pressure, in which the NaCl did not affect but ANP-pretreatment significantly attenuated the pressor magnitude. IV endothelin also increased the arterial pressure, which was potentiated by NaCl, ie, the maximum increase caused by the IV endothelin in the high NaCl vehicle was greater than the sum of that induced by endothelin (infused in normal NaCl vehicle) and that induced by high NaCl vehicle only. CONCLUSION: These results suggest that endothelin has separate central and peripheral pressor actions, in which the former is not affected by high NaCl but is attenuated by the ANP system and the latter is potentiated by high NaCl.

BACKGROUND: Left ventricular hypertrophy is an independent risk factor for coronary artery disease, hypertension or other cardiovasular diseases, and normal health person due to cardiac arrhythmia or coronary microcirculatory insufficiency. According to development of echocardiography, left ventricular mass and the patterns of left ventricular hypertrophy can be measured. Therefore, we tried to classify the left ventricular hypertrophy in coronary artery disease and to differentiate cardiac function and severity of coronary artery disease in these groups. METHOD: From September 1993 to August 1995, in 44 cases(23 males, 21 females) without hypertension with normal coronary angiography and 84 cases(62 males, 22 females) without hypertension with coronary artery disease on coronary angiography were compared by two-dimensional, M-mode, and Doppler echocardiography. RESULTS: In normal control group, mean age was 51+/-11years, and in coronary artery disease group, mean age was 58+/-10years. Atherosclerotic risk factors showed no significant differences in each groups. LVH patterns in normal control group were 31 cases(70%) of normal left ventricle, 6 cases(14%) concentric remodelling, 2 cases(5%) concentric hypertrophy, and 5 cases(11%) eccentric hypertrophy. In coronary artery disease group, 30 cases(36%) were normal left ventricle, 17 cases(20%) concentric remodelling, 14 cases(17%) concentric hypertrophy, and 23 cases(27%) eccentric hypertrophy. CONCLUSIONS: In this study, concentric and eccentric hypertrophy were more common in coronary artery disease group than normal control group. And comparing to one vessel disease grroup, multi-vessel disease group had more common concentric and eccentric hypertrophy. This result were considered that left ventricular concentric hypertrophy may induce coronary heart disease because more oxygen demand required and fixed coronary circulation, and essentric hypertrophy was due to post-infarct left ventricular remodelling and wall thinning.
