BACKGROUND: Our purpose was to assess the utility of prenatal triple-marker (alpha- fetoprotein (AFP), beta-human chorionic gonadotropin (hCG) and unconjugated estriol (uE3) testing for chromosomal abnormalities in women with Down syndrome screen-positive results. METHODS: Total 1,082 women between 15 and 21 weeks' gestation received second trimester Down syndrome risk evaluation by triple marker testing. AFP, beta-hCG and uE3 were measured by Coat-A-Count(R) IRMA (Diagnostic Products Corporation, LA, USA), The risk for Down syndrome was calculated using a commercially available software program (AFP Expert; Benetech Medical System, Toronto, Canada) by use of a Down syndrome risk cutoff value(1:270 at midtrimester). Karyotypes were reviewed for 32 (54.2%) of these patients who received prenatal chromosome analysis. RESULTS: Fifty nine (5.5%) patients of the 1,082 women screened were identified as positive. Two chromosome abnormalities (47,XYY and 46,XX, int (9) ) were found in the 32 patients who underwent prenatal chromosome analysis (6.3%). Any cases on the abnormal serum tests torn out not to be associated with trisomy 21. CONCLUSIONS: Although triple marker screen appears to be an effective method detecting chromosome abnormalities there is a high false positive rate. Therefore, new screening test that reduce false positive rate is need to be introduced.

The fifty gastrointestinal polyps, which were removed endoscopically frorn 47 patients at the Seoul National Univeraity. Hospital from January, 1978 to September, 1983, were reviewed with regard to the clinical and pathological features. The observed data are as follows; 1) Fifty polyps were reoved from 10 patients with gastric polyps and 37 patients with colonic polyps. Out of 37 patients 26 were male and 21 female, the sex ratio being 1.2: 1. 2) The gastric polyps were located in the body and antrum and 90 per cent of the colonic polyps were found in the left colon, especially in the rectosigmoid colon. 3) Out of the 10 gastric ployps snared, 8 could be retrivevd, 2 being lost. The histological examination showed that 3 were hyperplastic polyps, 2 gastritis verrucosa, 1 inflammatory polyp and the remaining 1 revealed intramucosel carcinoma with borderline epithelium. 4) Fourty polypectomies were performed in 37 patients with colonic polyps. Histological examination revealed that 24(60%) were adenomatous polyps, 9(22.5%) retention polyp, 4 (10.0%) inflammatory polyp and 3(7. 5%) Peutz-Jegher's poIyps. Among the adenomatous polys, 4 cases were complicated with focal adenocarcinoma. 5) Except the 2 cases of post-polypectomy bleeding, no other complication was encountered. The one case of hemorrhage after gastric polypectomy was treated with transfusion of 2 pints of whole blood, and the other case after colonic polypectomy required exploratory laparotomy because of inability of bleeding control by electrocoagulation.

Bowens disease is generally regarded as a premalignant dermatosis. If untreated, 3% to 5% of patients may develop squamous cell carcinoma. However, sebaciou carcinoma arising from Bowens disease is very rare. We presented a case of quarnous cell carcinoma and sebaceous circ s disease in a 68 year-old male. He had multiple bowenoid skin lesi nsties. A bean-sized nodule as developed on the bowenoid lesion of the he had a large yellow crust.ed exudative tumor on the Rt. thigh. We took a biopsy specimen of these three discrete lesions. The nu lipid stain of frozen section revealed Bowens disease, squarnous concllnoma arising from Bowen on the trunk and extremi Rt. lower abdomen. Almost of routine histology and carcinoma, and sebaceous carcinoma, respectively.
