An experimental study on the effect of the induced avascular necrosis of the femoral head on the femoral anteversion was made in the hips of 74 three to four-week-old rabbits. The results were as follows; l. In 18 of the 74 operated rabbits, a relative increase of anteversion was observed on the operated side, as compared with the nonoperated femur, the differences ranging from 10 to 75°(average increase was 25.9°). 2. Anteversion increase was actually internal rotation of femoral shaft starting from the subtrochanteric level and progressively increasing downward with spiral fashion. 3. The cause of anteversion increase was not proved in this experiment, but anteversion increase was a result of avascular necrosis.

The clinical and histopathologic study of 26 cases with tsutsugamushi disease seen at the Department of Derrnatology, Kosin Medical Center, Pusan, Korea from October 1986 to December 1988 was performed. The results were summarized as follows : 1. Age distribution was from 12 to 73 years and male to female ratio was 1: 1.2 (1P, males 14 females). 2. The disease occurred from September to December in a year. The peak incidence was in October (61.5%). 3. Major clinical manifestations were as follows : Chill, fever and headache (100 %), maculopapular eruption (90.2%), eschar (88.5%) and myalgia (84.6%). 4. Eschars were distributed on the abdomen (34.8%), chest (30.4%), leg (7.4%) and ot.her sites. 5. Histopathologic findings of the erythernatous macules in 24 patients showed epiderrnal changes including exocytosis of rnononuclear cells (66.7%), liquefaction degeneration of basal cells (54.2%), spongiosis (33.3%) and epidermal cell necrosis (29.2%). Dermal changes revealed vascular dilatation and perivascular infiltration of rnononuclear cells (100%), extravasated RBC (50%), and edema of papillary dermis (45.8%). Epidermal changes around the eschar were liquefaction degeneration of basal cells (52.2%), spongiosis (43.5%) and exocytosis of mononuclear cells (30.4%). Dermal changes included vascular dilatation and perivascular mononuclear cell infiltration (100%), vessel wall necrosis (73.9%), ederna of papillary dermis (65.2%) and endothelial cell swelling (65.2%).

A 47-year-old male patient presented us with erythematous, telangiectatic, purpuric or hyperpigmented patqhes, recurrent painful ulceration and ivory white atrophic scars on the lower portions of his legs, ankles and dorsal surfaces of both feet exacerbating on every summer for 5 years. The histopathalogical findings of an atrophic patch showed endothelial proliforetiion, partial occlusion of the dermal capillaries and fibrinoid material) on the superficial blood vessels, This patient was treated with aspirin and dipyriclamole for 4 months, and the skin lesions were improved significantly.

We report a case of Wells' syndrome consisting chiefly of papular, vesicular, pustular and vegetative lesions on the trunk, lower extremities and palms in a 48-year-old female, though characteristic lesions of this syndrome are known to be cellulitis or urticaria like plaques. Only a few cases with such lesions as ours have been reported until now. Histologic finding showed spongiotic vesicles in the epidermis and diffuse dense infiltration of eosinophils with characteristic flame figures in the dermis. In addition, marked blood eosinophilia was noted. We tried oral prednisolone for 3 weeks, and the skin lesions improved almost completely.

BACKGROUND: A fully automated enzyme-immunoassay (EIA) analyzer, Enzymun System, ES-300 (Boehringer Mannheim, Germany) uses streptavidin technology and performs single test or panels of up to 12 tests per run. We evaluated the results of ES-300 for anti-HCV by comparing the results with microplate-EIA, radioimmunoassay (RIA), and confirmatory test. METHODS: Total 79 sera (51 positive, 24 negative, 4 indeterminate results confirmed by Lucky HCD Confirm) were analysed. ES-300 with Enzymun-Test(R) Anti-HCV (Boehringer Mannheim, Germany) and microplate-EIA (Green Cross Center Innotest HCV 3.0(R)) were used. Fifty one sera were examined additionally by 2nd-generation RIA method, NANBDINE 125C(General Biologicals Corp., R.O.C.). And all results were compared to the results of Lucky HCD Confirm. RESULTS: The overall concordance rate of ES-300 and Innotest(R) was 72/79 (91.1%). The results of Lucky HCD Confirm on seven discrepant samples were five negative and two indeterminate. The results of ES-300 and NANBDINE 125C showed concordance rate of 90.2%. The sensitivity and specificity of ES-300 with regard to Lucky HCD Confirm were 94.5%, and 87.5%, respectively, and that of Innotest(R) were 98.2% and 66.7%, respectively. Clear distinction of positive and negative results by signal/cut off ratio was available in both EIAs. The positive predictive values of ES-300 and Innotest(R) were 94.5%, and 87.1%, respectively. CONCLUSIONS: ES-300 showed relatively good results in sensitivity and positive predictive value with regard to confirmatory test. In EIA-positive persons, however, follow-up study would be necessary for reliable evaluation of HCV infection.

OBJECTIVES: The purpose of this study is to evaluate effects of patients' age, amenorrhea duration, motivation, purpose, regimen, side effects on compliance to hormone replacement therapy(HRT) Methods: Compliance to HRT was assessed in 258 postmenopausal women who began HRT in the Menopause Clinic of Hangang Sacred Heart Hospital, Hallym university. One hundred sixty nine women who had intact uterus received continuous combined therapy with 0.625 mg of conjugated equine estrogen (CEE) and 100 mg of micronized progesterone. Eighty nine women who were hysterectomized received only 0.625 mg of CEE. RESULTS: A total of 103 women (39.9%) reported that they continued HRT at least for one year. Continuation of HRT was significantly more common among women who started HRT becuase of recommendation by gynecologist after hysterectomy in our department (p< 0.05). A greater percentage of women who received only CEE without uterus continued HRT than women who received continuous combined therapy (p< 0.05). Duration of amenorrhea, reasons for taking HRT and side effects such as irregular bleeding or breast tenderness were not related to the continuation of HRT. CONCLUSION: Education of menopausal women about the benefit/risk and side effects of HRT may be critical in improving compliance.

PURPOSE: MRI is known to be an effective imaging modality of the aorta and its role is steadily increasing in the evaluation of acquired aortic diseases including aortic dissections and aortic aneurysms. However, differentiation of the aortic dissections with thrombosed false lumen from the aortic aneurysm with mural thrombus in MRI has not been easy. Therefore, the authors tried to find the characteristic MR featrses which would to differentiate the two diseases. MATERIALS AND METHODS: MR images of 6 patients with thrombosed aortic dissection and 7 patients with thrombosed aortic aneurysms were reviewed retrospectively and compared in regand to shape and extent of thrombus, dimension of aorta, and luminal flow signal. RESULTS: Thrombosed aortic dissections showed sharply demarcated crescent shaped aortic wall thickening of even thickness involving long segment of the aorta, whereas thrombosed aortic aneurysms showed irregular aortic wall thickening of uneven thickness localized in the short dilated segment of the aorta. Characteristically aortic aneurysm with mural thrombus showed eccentric intraluminal slow flow signal. In contrast to the signal void of the true lumen in aortic dissections, the residual lumen of the aortic aneurysm with mural thrombus revealed intraluminal signal due to slow flow. CONCLUSION: Familiarity to these MRI findings of thrombosed aortic dissections and aortic aneurysms may lead to the accurate differential diagnosis in majority of cases.

Retroperitoneal tumors are relatively rare, accounting for 0.2% of all cancers; many different histologic types are present, and primitive retroperitoneal germ cell tumors constitute a small miniority of about 3%. Most primary extragonadal germ cell tumors (EGCTs) arise from the mediastinum of retroperitoneum in young males. The authors experienced a case of primary extragonadal mixed germ cell tumor with a 43-year-old woman complaining left lower abdominal pain. With the case report, a brief review was made.

Trichorrhexis nodosa(TN) denotes small node-like swelling with a loss of cuticle of the hair shaft through which the hair readily fractures. The basic cause of TN is mechanical or chemical trauma, and a contributing factor is an inherent weakness of the hair shaft. We report a case of localized TN in a 37-year-old male. He had an ovoid hair patch with multiple small white-gray dotted and stubby hairs localized to the right occipital scalp. TN is known to be the commonest of all hair shaft anomalies (Price, 1975). However TN is rarely reported, and there have been only four reports in Korean dermatological literature, to our knowledge, which might be due to underdiagnosis of this disorder. We postulated that diagnostic difficulty lies in the discrepancy between terminology and gross morphological findings.
