The present study was aimed at investigationg the usefulness of clinical stage, degree of histopatphological malignancy, p53 protein and PCNA labelded indices in deciding the prognosis, proliferation and infiltration of oral squamous cell carcinoma (SCC). Twenty-seven cases of SCC (seven were recurrent cases) were analyzed and 10 cases of non-specific inflammatory lesion served as control. Malignant scores were obtained with the Anneroth's classification. Proliferative activity of SCC in oral cavity was examined by means of proliferaling cell nuclear antigen (PCNA) and p53 protein immunostaining using DO7, PC10 (Novostra Co., U.K.) as primary antibody and biotinylated linked antibody (LSAB kit, Dako Co., U.S.A.) as secondary antibody. The labeled indices of PCNA and p53 were calculated by computer image analysis system in 400 multiplication microscopic fields. Results obtained were as follows : 1. The mean age of SCC group was 61.2 years. Seven of 20 cases had recurrence in 4 months after the operation, in which no significant correlation were noted between pre-and postoperative clinical stage, malignant scores, p53 protein and PCNA indices. 2. Positive immunostaining was noted in 65% (13 of 20 cases) on p53 protein and in 80% (16 of 20 cases) on PCNA. 3. Mean p53 protein and PCNA labeled indices were 24.71+/-27.86% and 41.49+/-2.51% in SCC group. They were high in SCC group than those in control group, although there was no signficant correlation between the two indices. 4. Mean malignant score was 15.22 0.64 in SCC group. There was no correlation between malignant score and clinical stage, and between malignant score and p53 protein or PCNA indices. 5. There was no signficant correlation between SCC and recurrent SCC group in malignant scores, p53 protein or PCNA indices. These results suggest that p53 and PCNA labeled indices have only limited usefulness in deciding the prognosis, proliferation and infiltration of oral squamous cell carcinoma.

Subcutaneous emphysema is a complication of the pneumoperitoneum necessary to perform laparoscopy and will be seen more often as laparoscopic techniques are applied to a growing number of intraabdominal procedures. We report a case of subcutaneous emphysema and hypercarbia without pneumothorax or pneumomediastinum during laparoscopic cholecystectomy, which was treated by multiple puncture with 18G needle on emphysematous site. The suspected cause is inadvertent subcutaneous insufflation of carbon dioxide through the trocar sites by increased intra-abdominal pressure for the establishment of pneumoperitoneum. Immediate recognition, evaluation, and treatment of subcutaneous emphysema is necessary since this can be life-threatening complication.

PURPOSE: Segmental parenchymal excretion delay on Tc-99m DISIDA scan is caused by intrahepatic bile duct obstruction. However, the diagmostic value for intrahepatic bile duct obstruction is unknown. We conducted this study to assess the positive predictive value of segmental excretiom delay for the diagnosis of intrahepatic bile duct obstruction, and additional benefit over other noninvasive radiologic studies. MATERIALS AND METHODS: The study population consisted of 43 patients (48 scans) Who showed segmental parenchymal excretion delay on Tc-99m DISIDA scan. The results of abdominal CT or ultrasonography, which was done within 1 month of Tc-99m DISIDA scan, were compared with scintigraphic findings. RESULTS: The etiology of segmental parenchymal excretion delay was determined by ERC or PTC in 31 scans, and follow-up studies in 13 scans. No causes were identified in 4 scans. The positive predictive value of segmental parenchymal excretion delay for intrahepatic bile duct obstruction was 92% (44/48). On the other hand, 13% (5/38) of CT and 28% (5/18) of ultrasonography were normal. In 18% (7/38) of CT and 17% (3/18) of ultrasonography, only intraheipatic bile duct dilatation was noted without any diagnostic findings of intrahepatic bile duct obstruction. CONCLUSION: Segmental parenchymal excretion delay on Tc-99rn DISIDA scan had a high positive predictive value for the diagnosis of intrahepatic bile duct obstruction. Tc-99m DISIDA scan may be useful for the diagnosis of intrahepatic bile duct obstruction, especially in patients with nondiagnostic CT or ultrasonography. The diagnostic usefulness need to be confirmed by further prospective studies. KW: Tc-99m DISIDA, Segmental parenchymal excretion delay, Intrahepatic bile duct obstruction.

Breast Cancer in women poses a problem, and it can be difficult at times to evaluate the possibility of the cancer's recurrence in node negative early cancer. Reliable prognostic markers are needed in breast-cancer management to help clinicians identify patient with high risk of recurrence and arrive at more rational decisions for proper treatment. E-cadherin is a glycoprotein that mediates Ca2 -dependent cell-cell adhesion and maintenance of the epithelial cell phenotype. It has been implicated as an invasion-suppressing protein in experimental systems and in human tumors, and alterations in the cadherin function have been implicated in tumor progression in a number of adenocarcinomas. In this study, the expression of E-cadherin was reduced in 35.3% of the case reviewed(12/34), and we could find no clinical relation between the known prognostic factors except tumor stage(p<0.05), and the degree of E-cadherin expression.

It has been thought for many years that gastric adenocarcinoma almost never crosses the pylorus. Although this theory was generally accepted, several studies have refuted it. We report three cases of gastric adenocarcinoma direct spreading into the duodenum that was diagnosed by endoscopic duodenal biopsy and review the literature.
