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)

BACKGROUND: Tinea faciale usually has been classified as tinea corgoris. Recently it has often been classified as a seperate disease recently because of its various clinicel pesentations. OBJECTIVE: Our purpose was to evaluate the clinical characteristics and mycological findings of tinea faciale, METHODS: Clinieal and mycological study was done with 42 eases of tinea faciale among out-patients examined for eight years from January 1985 to December 1992 at Yeungnam University Hospital, Taegu, Korea. RESULTS & CONCLUSION: 1. The average of annual distribution of patients was five and there a as no significant difference according to year. The age distribution of patients was highest under age 10(33.4%). The ratio of male to female patient was 3.1: 1. Monthly or seasonal distribution if patients was not significantly different. 2. Of 42 cases, causative organisms were isolated in 31 cases. They are Trichophyton(T.) rubrum in 19 cases (61.3%), Microsporum(M.) canis in 6 cases (19.4%), T. mentcgrophytes in 5 cases (16.1%) and M. gypseum in 1 case(3.7%) in tbe order of decreasing frequncd M. canis was the main causative organisrn in children under age 10. In the age group after 10, T. rubrum was predominated. T. rubrum infection was most frequently seen in spring, T. mentagrphates infection was seen more in winter and M. canis infectior in autumn. 3. Classic annular types were seen most frequently in the cases caused by T. rubrum and T. mentagrophytes. Papular types were seen most commonly in the case caused by M. canis. Multiple facial lesions were seen in T. rubrum infection (2 cases) and Of canis infection (1 case). Tinea faciale simulated several other dermatoses. These were contact, dermatitis, lupus erythematosus, photosensitive dermatosis, rosacea, granuloma annulare and acne. Of these, tinea faciale simulated contact dermatitis most frequently. Coexisting fungal infections were found in 7 patients and tinea corporis was most frequently present. Topical antifungsl agent was tried alone in 22 cases, and topical and systemic antifungal agent were combined in 20 cases.
