Despite the rapid development of assisted reproductive technologies (ART) in recent years, implantation rates after replacement of embryos into the uterine cavity remains low. Several techniques such as culture conditions based on formulations of human tubal fluid and various ART techniques as GIFT, ZIFT, TET have been adopted in recent years to improve embryo viability in vitro and implantation rates. Also, coculture of human IVF-derived embryos have been used in an effort to increase the number of viable embryos following IVF and to improve synchrony between the developing embryo and the uterine environment. The aim of this study was to evaluate whether the use of coculture with autologous cumulus cells has a significant beneficial effect on the development of embryos in vitro and its relation to the pregnancy rates in 120 patients with previous failed IVF-ET from September, 1995 to January 1998. We obtained the results from which significant improvement in the quality of viable embryos were observed using a coculture system with autologous cumulus cells, but pregnancy rates in this group of patients did not differ from the rate in the standard IVF group during the same period. Our study shows that a simplified short-term coculture system with autologous cumulus cells may help rescue moderate quality embryos to cleave regularly.

PURPOSE: To evaluate the clinical characteristics, treatments and outcome of patients with hemorrhagic shock and encephalopathy(HSE) syndrome. METHODS: We performed a clinical study on 14 patients who were diagnosed as hemorrhagic shock and having encephalopathy syndrome in the Department of Pediatrics, from 1984 to 1998. Age, sex, clinical symptoms and physical findings at admission, the most deranged laboratory findings, radiologic findings, treatments and outcome were analyzed. RESULTS: The age of onset was 1.0+/-0.9 years and the male to female ratio was 1: 1.8. At admission, clinical findings included dehydration in 85.7%, shock in 85.7%, fever in 71.4%, vomiting in 71.4%, diarrhea in 64.3%, GI bleeding in 50%, convulsion in 42.9%, and edema in 35.7%. Altered mental state was found in 100%, hepatomegaly in 64.3%, and splenomegaly in 21.4%. Laboratory findings revealed D-dimer positive in 92.9%, the mean hemoglobin level 8.2+/-2.1g/dL, BUN 35.7+/-24.0mg/dL, creatinine 1.9+/-1.5mg/dL, AST 561.0+/-1,412.1IU/L, ALT 858.9+/-1,649.8IU/L, blood glucose 229.5+/-197.4mg/dL, ammonia 195.4+/-129.7pg/dL, and total bilirubin 4.9+/-8.2mg/dL. On serologic tests, rotavirus and Epstein-Barr virus was found in 1 patient(7.1%), respectively. The mortality rate was 78.6%. CONCLUSION: We found that shock and disseminated intravascular coagulation(DIC) played important roles in the pathogensis of HSE syndrome, and encephalopathy, hepatic and renal insufficiency, and respiratory failure were secondary complications resulting from shock and DIC. Despite vigorous treatment, the prognosis was very poor. We feel more efforts should be focused on investigating the etiology and pathophysiology of HSE to prevent as well as develop a specific therapy. (J Korean Pediatr Soc 2000;43:814-819)

Lichenoid drug eruption is lichenoid skin eruptions caused by certain drugs and compounds, and can be identical or similiar to lichen planus. A 75-year-old woman who had taken antituberculosis medication(INH, ethambutol, rifampin) for 4 months developed pruritic generalized erythematous papular eruptions on the trunk and extremities, alopecia and nail dystropy. Histopathologic findings were hyperkeratosis, hypergranulosis, hyc rophic degenaration of basal layer, band like lymphohistiocytic infiltration in the upper dermis and perivascular lymphohistiocytic infiltration in the deep dermis. She was treated with systemic corticosteroid, and then skin lesion were slightly improved. After termination of antituberculosis medication, skin lesions were markedly improved with residual hyperpigmentation. Alopecia and nail dystrophy were also improved.

BACKGROUND: In tinea pedis, the response of treatment and prognosis are different according to clinical types. Positivity in KOH mount and causative agent in culture are also different. OBJECTIVE: Our purpose was to evaluate the clinical characteristics and mycologic findings of tinea pedis according to the clinical type. METHODS: A clinical and mycological study was conducted with 97 cases of tinea pedis among out patients examined for 7 months from June 1994 to December 1994 at Yeungnam University Hospital and Catholic Skin Clizic, Taegu, Korea. RESULTS: 1. Age distribution showed patients in their fourth decade to be most common. The ratio of male to female was 1.2: 1. The distribution of patients by clinical type was interdigital type, interdigital combined with hyperkeratotic type, interdigital combined with vesicular type, hyperkeratotic type, and hyperkeratotic combined with vesicular type, in descending order. One to five years was the most comrrion duration of tinea pedis. Duration of tinea pedis was the shortest in the vesicular type, otherwis was longer in hyperkeratotic type. Rate of family history of tinea pedis was 54.6%. The larger the size of family was, the higher the positivity in family history. The rate of coexistent dermatiophytosis with tinea pedis was 39.1%, and tinea unguium was the most common one. 2. The isolated dermatophytis were T. rubrum, 90.7%, T. mentagrophytes, 7.2%, and T. rubrum rnixed with T. mentagrophytes, 2.1%. T. rubrum showed an even distribution in all clinical types of tinea pedis whereas T. mentanophytes was isolated only in the interdigital type, vesicular type, and interdigital combined with vesicular type. T. rubrum mixed with T. mentagrophytes was isolated in the interdigital combine with vesicular type. Distribution of dermatophytes was relatively even arnong the age groups. T. rubrum showed a relatively even distribution in duration of tinea pedis, but T. mentagrophytes was isolated in tinea pedis with shorter duration.

Angiosarcoma is a rare malignant vascular tumor of endothelial cell origin, Cutaneous angiosarcoma usually occurs on the scalp and face of the elderly and most frequently in the sixth and seventh decade. We presented a case of angicisarcoma in a 70 year old woman. The patient had a well-demarcated, 3 x 3cm sized, dark brownish-colored, ulcerative nodule on the vertex with hemorrhagic bulla on the right. temporal scalp. Histopathologic examination of the nodule showed a well differentiated tumor with irregular anastomosing scular channels lined by atypical endothelial cells in the dermis and subcutaneous fat. Immunohistochenlical study for factorVlll-related antigen was partially positive in tumor channels. She was treated by wide surgical excision but she expired 5 months after discharge from the hospital.
