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.

Prior to 1988, endometrial cancer was clinically staged but there was the considerable discrepancy between clinical and aetual stage. FIGO surgical staging classification of endometrial cancer(I988) provides the advanatage of recognizing the true disease distribution and extension, and more rational treatraent can be accomplished. This retrospective study was based on a clinical review of 73 patients with endometrial carcinoma from l982 through 1991 who underwent primary surgical evaluation. A11 cases were restaged ueing the newly adopted FIGO surgical staging. The distribution of FIGO clinical staging was as follows:85 patients(89.1%) were with stage I, 5(6.9%) with stage II, 2(2.7%) with stage III and 1(l.3%) with stage IV. Surgical restaging according new FlG0 classification reveald 56(76.7%) patients with stage I, 1(1.4%) with stage II, 14(19.2%) with stage III and 2(2.7%) with stage IV. Surgery upstaged 12.3% of clinical stage I patients, In clinical stage II patients, 80.0% was doenstaged. There wes no stage changing in cliaical stage III and IV patients. The acturial survival rates for surgical stages I a, I b, I c, and III were 80.0%, 77.2%, 68.4A%, and 35.0% respectively. By using FIGO surgical staging, the initial extent of endometrial cancer can be more accurately evaluated and we may predict prognosis and survival relatively well.

We report two cases of vulvar syringorna in a 40-year-old women and a 28-year-old woman who had 2-3mm sized, brownish papules on both valvar areas an l-3rnm sized, yellow-brownish papules on both vulvar ares with yellowish milia-like lesion the surface, respectively. Microscopically the lesions revealed characteristic findings of syrinzoiza However the second case showed a small cystic duct in the papillary dermis, which is lineilly a stratified epithelium and filled with concenteric lamellae of keratin.

The first description on the discoid meniscus was made by Young in 1889 and was known as it affects only the lateral meniscus for a long time. However, Cave and Staples had reported the two cases of discoid changes on medial meniscus in 1941. Smillie(1948) had stated that the menisci exist as cartilagenous discs at an early stage of fetus and remain in discoid shape congenitally. Kaplan(1957) reported that the discoid meniscus is not caused by congenitally but acquired in relation of joint motion. A clinical analysis is made on the 22 discoid meniscus which were removed surgically and summarized as follows: 1. The click sound on walking, tenderness and positive McMurray test were important as diagnostic criteria and were present all of the cases. 2. The most of the discoid meniscus were found in first and second decade in 13 cases(76.5%) out of 22. The five cases were bilateral. 3. The discoid change of the meniscus had no sex defferences in their incidence but lateral involvement were far superior than in ten times. 4. The discoid meniscus shows degenerative change microscopically 17(77.3%). 5. The clinical result of surgical removal of discoid meniscus was satisfactory in resuming their full activities in six weeks.

Prognosis in carcinona of the ulerine cervix appears to be influenced by multiple factors (the size of primary tumor, nodal status, deep invasion into cervical stroma, histologic grade etc) that are frequently in terrelated. Recently other new factors may have been propoeed as prognostic factors in cervical cancer, such as number of cells in S-phase, or act,ivation of c- Ha-ras nnnd c-myc protooncogenes. It has been sug gested that c-myc proto-ancogene is associated with cellular proliferation and that its inappvopriate expression may be involved in carcinogerieais and in tumor progression. But its status as prognostic factor in cervical cancer is controversal. So we studied 42 with normal cervix and 61 wiith cervical carcinorna to investigate the relatiarship betwveer the prognostic variables of the cervical cancer(age, stage, tumor size, depth of invasion, lymph node metastasia) and c-myc gene expression, analyzed uaing immunohistochemical stainirig with formalin fixed paraffin embedded tissues from January 1985 to December 1986. And we assessed the progrioatic signifieance of r, myc gene expression by multivariate analysis. There was, significant, difference in c-myc gene expression between the normal cervix and the invasive cervical carcinama(0%: 34.4%, p<0.001). And the c-myc gene expressian was increased significantly according to clinical stage and depth of invasion. But, no relationship was found between c myc overexpression and other clinical ancl histologic parameters, such as age, primary tunaor size and lymph node metastasis. The 5 year disease free survival rates of the patients whose tumors showed c-myc overexpression were significantly lower(23.1%) than that(50.0%) of Other cancer patients. But only lymph node metastasis was significant]y related to the relative risk of relapse when the multivariate analysis was performed. These results suggested that c-myc gene expression may be associated with the cervieal tumorigenesis, but not useful as an indepenclent pragnoetic factor of the cervical carcinoma.

This phase II study aimed to assess the clinical activity and toxicity of ifosfamide based regimen in patients with epithelial ovarian cancer, relapsed or refractory to cisplatin-containing combination chemotherapy. From July 1991 to June 1993, 18 patients with epithelial ovarian cancer, relapsed or refractory to cisplatin were treated as follows. Relapsed cases were treated with IP(ifosfamide 4,0g/m2 intravenously and cisplatin 60mg/m2 intravenously on day 1) regimen every 3-4 weeks. The regimen used in refractory cases was Et-I(etoposide 100mg/m2 intravenously on days 1 to 3 and ifosfamide 1.0g/m2 intravenously on days 1 to 5) regimen every 3 or 4 weeks. The uroprotectant mesna was concomitantly used. Responses and toxicities were evaluated according to the WHO Criteria. The overall response rate was 27.8%(5/18), including 2 complete response and 3 partial response. There were four episodes(22.2%) of grade 3, 4 myelosuppression, but no other grade 3, 4 non-hematologic toxicity. Salvage therapy with ifosfamide based regimen is a useful and well tolerated treatment strategy in selected patients with relapsed ovarian cancer.
