The presense of the esophageal varices might have a partial machanical obstruction and cushion effect on esophageal lumen due to blood within the varices. It may affect on the motility and acid clearance in the esophagus. The aim of this study was to evaluate the acid clearance and the esophageal motility according to the degree of the varices in patients with esophageal varices. We have performed esophageal manometry and acid clearance test in 41 patients with esophageal varices. Esophageal motility disorder was abserved in 29.4% of patients with esophageal varices. The number of swallowing for acid clearance was significantly increased in patients with esophageal varices than control group(23.5 +/- 14.1 Vs 6.1 +/- 1.6, p=0.004). However, there was no significant corelation with form, location, and redcolor sign of the varices. In conclusion, patients with esophageal varices accompanied esophageal motility disorders and delayed acid clearance. This results might be a useful referance data for changes in esophageal motility before and after treatment of esophageal varices.

Pheochromocytoma is relatively uncommon disease that is mostly originated from adrenal medulla. Most of pheochromocytoma are benign, and malignant pheochromocytoma are very rate. A case of malignant pheochromocytoma from the right adrenal gland in a 28 year old woman was successfully treated with surgical intervention. This is a rare malignant pheochromocytoma case report with review of literatures.

A clinicopathological study was made on 17 case with leukemia cutis diagnosed in a period of 10 years frorn 1980 to 1989 in Seoul Xational University I-lospital. The results were summarized as follows : 1. There were 4 cases with acute lyrnphocytic leukernia, 7 with acute myelocytir. leukemia (AML), 5 with chronic myelocytic leukemia (CML), 1 with eosinophilic leukemia. 2. The clinical appearance of leukemia cutis included nodules (88.2%), papules, macules, plaques and ulcerative lesions. Leukemia cutis dis not show any discernible clinical qppearance with each different type of leukemia. 3. Leukemia cutis showed a wide spectrum of histopathologic features, diffuse infiltration, patchy infiltration with linear infiltration between collagen bundles, perivascular and peridnexal involvement, perivascular involvement, and mainly subcutaneous tissue involvement. There was no distinctive histopathologic pattern with each different type of leukemia. 4. The demonstration of intracytoplasmic chloroacetate esterase and lysozyme was helpful to refine the diagnosis of leukemia cutis.

Software modules for interactive display, manipulation and retrieval of medical images have been designed for a Picture Archiving and Communications System (PACS). The target of these modules is not for a high-end diagnostic workstation for radiologists, but for a PC-based low cost clinical workstation for a referring physician. This software is constructed based on a concept of an object-oriented language which is designed to be modular and expandable. It consists of several functional modules: (a) a communication module for image retrieval, (b) a standard module for the interpretation of the DICOM images, (c) a user interface module for the non-computer oriented clinicians and (d) a tool module for viewing and manipulating images as well as editing the annotation.

BACKGROUND: There are few epidemiological studies on patch test with additional batteries in Korea. OBJECTIVE: We report the results of patch tests with additional batteries which are relatively uncommonly used in contact dermatitis patients. METHODS: Standard patch testing was performed with Finn chamber on Scanpor tape. We used additional batteries including cosmetic and fragrance series which are commonly used, and the others including 14 batteries(so-called ""other"" batteries). RESULTS: Over the last 8 years, 719 patients (male 184, female 535) were tested in our contact, dermatitis clinic. 178 patients (24.8%) were tested with both Standard and other batteries, In other batteries, rubber additive series were most frequently used (9.2%), and textile colours finish (4.3%) and hairdressing series (3.6%) were used in order of frequency. Rarely performed batteries were (meth) acrylate ser ies, photographic chemicals series, wood set, oil & cooling fluid series, and various allergens. Patients tested with steroid batteries did not show positive reactions. CONCLUSION: We suggest that 6 batteries ((meth)acrylate series, photographic chernicals series, wood set, oil & cooling fluid series, various allergens, steroid battery) have law testing frequencies and positive rates. A more organized multicenter study is required.

PURPOSE: We compared the safety of the double-stapling method with that of the hand-sewn method when performing a Billroth I anastomosis (BI) after a radical subtotal gastrectomy. METHODS: Fifty-three (53) patients who received a BI with stapler from February 1998 to April 1999 were compared with 24 patients who received a BI with the hand-sewn method from January 1996 to December 1998. All the patients were divided into three groups according to the type of reconstruction: Group 1 (n=42), double- stapling method, Group 2 (n=11), anastomosis through posterior gastric wall, and Group 3 (n=24), hand- sewn method. The length of the greater curvature, lesser curvature, and proximal margin and the number of resected lymph nodes were compared for radicality, and the incidence of complications was reviewed. ANOVA and the chi-square test were used for the statistical analysis. RESULTS: The mean ages were 55.2+/-10.8, 59.8+/-9.7, and 54.7+/-11.9 years for groups 1, 2, and 3, respectively. The sex ratios were 2.2:1, 1.2:1, and 1.4:1. The lengths (cm) of the greater curvature were 17.2+/-2.5, 18.4+/-2.5, and 18.6+/-3.3, and the lengths of the lesser curvature were 10.4+/-1.5, 10.9+/-1.6, and 10.7+/-2.1; however, the differences were not statistically significant (p>0.05). The lengths of the proximal resection margin were 5.4+/-2.5, 8.2+/-3.3, and 6.0+/-3.2 (p<0.05), and the numbers of resected lymph nodes were 25.3+/-8.3, 19.1+/-5.8, and 32.+/- 13.7 (p<0.01). We experienced no complication in any group, except one case of leakage in the hand-sewn group. CONCLUSION: The double-stapling technique is a safe operative method in BI after a radical subtotal gastrectomy with its very low complication rate. Especially, the so- called Tornado method is a more useful method since it doesn't need a gastrotomy in the remnant stomach.

Dysgerminoma developed in a 21-year-old phenotypic female patient with 46,XY pure gonadal dysgenesis, Swyer syndrome. This patient presented with pelvic mass associated with abdominal pain and primay amenorrhea. Clinical characteristics showed a typical stigmata of gonadal dysgenesis: primary amenorrhea, sexual infantilism, a small uterus and left streak gonad. A 46,XY karyotype was made by lymphocyte culture. The patient was counseled to undergo operation, chemotherapy and hormon therapy. She underwent bilateral gonadectomy with total hysterectomy, partial omentectomy and multiple pelvic wall random biopsy. Histological examination revealed dysgenetic gonads with dysgerminoma. After surgery, the patient received chemotherapy and also was started on hormone replacement therapy. She is currently alive with no evidence of disease after 19 months from surgery.
