Duodenal gastrointestinal stromal tumors (GISTs) are uncommon and a relatively small subset of GISTs whose optimal surgical procedure has not been well defined. Because submucosal spread and local lymph node involvement is infrequent in GISTs, wide margins with routine lymph node dissection may not be required. Various techniques of limited resection for duodenal GISTs have been described depending on the site and the size of the tumors. In this study, we report two cases of GIST involving the third and fourth portion of the duodenum successfully treated by segmental duodenectomy with end-to-end duodenojejunostomy. This technique should be considered as a treatment option for GIST located at the third and fourth portion of the duodenum.

Cystoscopy is important in staging of cervix cancer. However, there have been controversies about its routine use, interpretation of the result and necessity of biopsy during cystoscopy. Herein we analysed 1,049 cases. Among 1,049, 53 abnormalities (5.1 %) were found.; 22 grossly visible tumor invasion (2.1 %), 30 bullous edema (2.9 %), 1 transitional cell carcinoma (0.1 %). Transurethral biopsy was done on 14 cases with gross tumor invasion and 13 (92.9 %) showed microscopic bladder mucosa invasion, all of which were in from stage II b to IV. Bullous edema was analyzed by biopsy results, operative findings and computed tomography scan in 25 cases.; 13 bladder muscle invasion (52 %), 2 bladder mucosa invasion (8%), 5 normal bladder wall (20 %), 5 nonspecific inflammation (20 %). However, cystoscopic biopsy was unreliable in evaluation of bullous edema. Biopsy confirmed bladder mucosa invasion were found in 15 of 1,049 (1.4 %).; stage 0 to II a 0. stage II b 2.4%, III 11.3%, IV 15%. We conclude that cystoscopy is useful only in stage more than II b, bullous edema means bladder wall invasion in majority of cases and should be evaluated by noninvasive computed tomography and that biopsy should be reserved only in suspicious cases.

BACKGROUND: Several keratolytic agents have been used in many dirmatologic conditions such as callus, keratosis palmaris of plantaris, however the evaluation method of the effects of keratolytiic agents has not been good enough in clinical use. OBJECT: We have conducted an investigation to measure the effect of several keratolytic agents using an in vitro model. METHOD: We measured the fegraded protein of keratin by the bui iet method after adding enzymes such as trypsin, pepsin and papain, and irritants, salicylic acid and sodii m lauryl sulfate to the collected callus. RESULT: The order of the keratolytic effect of the enzymes was trypsir >pepsin>papain. It was difficult to detect the keratolytic effect of salicylic acid becaues of color hiidrance and there was an increasing tendency of keratolyti effect of sodium lauryl sulfate, however it was prominent mainly at a high concentration. CONCLUSION: These results suggested that the potency of similar types of keratolytic enzymes such as pepsin, trypsin and papain can be possible. However it was not such a sitable model to check the potency of the keratolytic effect of salicylic acid and the eoncentration tevel may be an important factor for certain kinds of chemicals such as sodium lauryl sulfate.

The positive binding activity of lectin, peanut agglutinin (PNA), against the mucinous malignancies of the ovary was studied in order to clarify biologic differences among those lesions using immunoperoxidase method (ABC). A total of 23 cases were included in this study and they were classified as 10 cases of mucinous cystadenocarcinoma, 9 mucinous tumors of borderline malignancy and 4 pseudomyxoma peritonei, histologically. Nine of 10 cystadenocarcinomas and all cases of pseuomyxoma peritonei showed more than moderate degree of positive binding activity (>2+) with PNA in the neoplastic epithelial cells. In the cases of borderline malignancy, only 3 of 9 revealed as much similar binding pattern with PNA as cystadenocarcinoma group, in contrast, minimal degree of positivity (1+) was noted in the remainder. These findings may suggest heterogeneity in the biochemical characteristics among the cases of borderline lesion. And it is proposed that the higher PNA binding cases in ovarian mucinous borderline malignancy require extensive sampling by multiple sections and further careful follow-up study.
