BACKGROUND: Neopterin is released from monocytes/macrophages specifically by stimulation with interferon-γ. Therefore the increase refers to the activation of T lymphocytes. OBJECTIVE: Our objective was to examine the potential role of neopterin in the cell mediated immune response to Behçet's disease. METHODS: We studied 67 patients of Behçet's disease classified by Shimizu and a control group of 30 normal healthy people. Serum neopterin was detected by radioimmunoassay technique. RESULTS: The serum neopterin concentration of the group with Behçet's disease was significantly elevated, compared with the control group (6.36 nmol/ml vs 3.63 nmol/ml). The increase of neopterin concentration was well correlated to the clinical severity of the diseases in increasing order. CONCLUSION: Our data suggest that the T lymphocyte derived IFN-γ which stimulates the production of neopterin has some role in the pathogenesis and clinical severity of Behçet's disease.

Purpose: Additional surgery is recommended for patients after a non-curative endoscopic submucosal dissection (ESD) to prevent residual cancer (RC) or lymph node metastasis (LNM). We aimed to evaluate the clinicopathologic characteristics of patients who underwent an additional gastrectomy after a non-curative ESD procedure and identify the risk factors of RC and LNM. Methods: We retrospectively assessed the clinicopathological factors of 73 patients who underwent additional gastrectomy following a non-curative ESD between January 2009 and December 2019 at our center. Results: RC and LNM rates after additional gastrectomy were 9.6% and 8.2%, respectively. Invasion deeper than 500 μm (P = 0.045), positive horizontal resection margin (P < 0.001), and positive ESD margin (P = 0.001) were identified as statistically significant factors in univariate analysis for RC, but not in multivariate analysis. Lymphatic invasion was the only risk factor found to be significant in both univariate and multivariate analyses (P = 0.005 and P = 0.012). Conclusion Additional gastrectomy is necessary to prevent RC or LNM after non-curative ESD. Lymphatic invasion was also associated with LNM in patients who underwent an additional gastrectomy after a non-curative ESD, and in such cases, active treatment is required.

Cardioplegic myocardial protection has become the most popular method for coronary artery bypass surgery. In contrast, we reported 17 consecutive coronary artery bypass operations with ventricular fibrilation, nitroglycerine infusion, and moderate hypothermia. The average patients age was 55 years. 11 patients had stable angina, 4 patients unstable angina, 2 patients varient angina, and 6 patients had prior myocardial infarcation. On cardiac catheterization, the mean LVEDP was 17.32+/-2.13mmHg, EF was 0.67, and abnormal LV wall motion was noted in 5 patients. Premedication usually consisted of hydroxyzine 1~3mg/kg with or without morphine 0.05~0.1mg/kg IM. Induction agents was morphine sulfate, diazepam, lidocaine and pancuronium for muscle relaxant. Maintaninance agents were nitrous oxide, morphine with small dose of halothane or enflurane. Almost all case (15 patient) was infused nitroglycerine 0.5~1.5 microg/kg throughout entire procedure. After bypass, average patient's temperature maintained 25~28 degrees C, and ventricular fibrillation were induced with or without cold saline irrigation around the heart. Average mean arterial pressure were maintained 60~80 mmHg during bypass period. At the end of bypass, if spontaneous beating were not occurred under normal temperature, defibrillation were used. After bypass stop, methylprednisolone were injected in 15 patients. Average anesthetic time was 585 min., surgery time was 529 min, bypass time was 237 min. Arterial blood gas and electrolyte was acceptable range during all period. Complication implicated with anesthesia was myocardial infarction (3 patient), arrhythmia and transient vocal cord paralysis, 1 patient, respectively and no mortality. In all cases the anginal pain was improved.

Progressive multifocal leukoencephalopathy (PML) is a rare disease that occurs mainly in immunocompromised patients. Despite the progressive nature of the disease, the changes on MRI during the disease course - which may help in monitoring the disease process - have seldom been reported. Here we describe a patient with polymerase-chain-reaction-proven PML examined using serial diffusion-weighted imaging (DWI) and apparent-diffusion-coefficient mapping. Magnetic resonance spectroscopy (MRS) revealed that the demyelinating process was more active without significant neuronal loss at the newer and advancing edge of a lesion than in the older central part of the lesion. This case shows that MRI findings such as DWI and MRS may improve the diagnosis and the understanding of the pathophysiology of PML.

PURPOSE: Peritoneal seeding is the most common type of metastasis or recurrence and one of the poor prognostic factors in gastric cancer. Moreover, there are as yet no effective treatment modalities available. Recently some research groups suggested the benefit of combined cytoreductive surgery and intraperitoneal chemotherapy, but the related experiments remain in the trial stage. Therefore, we assessed the safety and evaluated the efficacy of combined cytoreductive surgery and early postoperative intraperitoneal chemotherapy (EPIC) in gastric cancer patients with peritoneal carcinomatosis of gastric cancer. MATERIALS AND METHODS: From Nov. 1997 to May. 2002, eighteen cases of combined cytoreduction and EPIC were performed in the Korea Cancer Center Hospital due to gastric cancer with peritoneal carcinomatosis. The control group consisted of 33 patients who had no resection without EPIC during the same periods. After combined cytoreductive surgery and EPIC, all patients received systemic chemotheraphy with the exception of 2 patients who could not tolerate the treatment. We retrospectively investigated the clinicopathologic features and analyzed the factors affecting the prognosis. Median follow-up period was 11.9 months (range 0.5~61 months). Statistical analysis was performed by SPSS 11.0 for Windows. A P-value less than 0.05 was considered as statistically significant. RESULTS: There was one case of the treatment-related mortality (5.5%) and seven cases of treatment-related complications (38%) in the combined cytoreductive surgery and intraperitoneal chemotherapy group. One-, 3- and 5-year survival rates of cytoreductive surgery plus EPIC were 57.6%, 25.9% and 13.0%, respectively, and those of the control group were 18.2%, 3% and 0%, respectively. Survival of the combined cytoreductive surgery plus EPIC group was better than that of the control group (p=0.0026). In multivariate analysis of prognostic factors affecting the survival, combined cytoreductive surgery plus EPIC (p=0.02) and systemic chemotherapy (p=0.019) were independent prognostic factors. CONCLUSION: Although a small number of cases were included in this study, combined cytoreductive surgery plus EPIC showed survival benefit and retained a comparable complication rate compared with the control group.

Although extrahepatic metastasis of hepatocellular carcinoma are frequent as about 64%, implants involving the peritoneum are rare. We presented a cases, whieh is hepatocellular carcinoma with metastasis to visceral peritoneum revealing multiple, hard, variable-sized and nodular mass including large mass over 10 cm in size. The presence of tumor was diagnosed by serum alpha fetoprotein, abdaminal CT, celiac and SMA angiography and biopsy with laparoscopy.
