Behcet's syndrome has been known as multisystemic disease caused by nonspecific immune mediated vasculitis, but it's precise etiology is not yet identified. Among the various systemic manifestations, pericardial effusion is extremely rare, and pericardial tamponade caused by massive pericardial effusion in Behcet'sydrome has not been reported in the literature. We report a case of Behcet's syndrome manifested as SVC syndrome due to SVC and right atrial thrombus with massive pericardial effusion resulting cardiac tamponade with the review of the literature.

We previously reported that transgenic mice produced with a transgene consisting of the SV40 T antigen and vasopressin without the 3'-flanking region exhibit brain tumors and lymphoma. In this study, transgenic mice were produced with the fusion gene containing the SV40 T antigen and the whole vasopressin gene with the 3'-flanking region. Six transgenic mice were generated, five which died after 2-6 weeks. The remaining founder mouse was investigated for fusion gene expression and tumor progression at the age of 6 weeks. Brain tumor cells were characterized for phenotypes and transgene expression. During in vitro cell cultures, the phenotypic appearances at 10, 20, and 30 passages were as a uniform monolayer with similar growth rates. The site of SV40 T antigen integration was in the A2 region of chromosome 11, and SV40 T antigen was expressed at the same level in cells of both earlier and later passages. Thirty passages were probably insufficient to reach crisis and immortalization. These cells enriched brain tumor cell compositions with astrocytes and neuronal cells.

BACKGROUND: Although many treatments for advanced gastric cancer have been developed, only poor treatment results have generally been obtained. We performed a prospective study on the combination chemotherapy of paclitaxel and cisplatin (PC). The primary objectives of the study were elucidating the disease response and evaluating the drug regimen's safety. METHODS: Patients with metastatic or recurrent gastric cancer received intravenous paclitaxel 175 mg/m2, and cisplatin 70 mg/m2 on day 1. This cycle was repeated every 3 weeks. RESULTS: From January 2000 to March 2004, 37 patients from 3 different hospitals were enrolled in this study. A total of 135 treatment cycles (median: 3 cycles) were administered. The responses were evaluable in 34 patients; 24 patients received this regimen as their first-line treatment for metastatic cancer and the other patients received it as their second-line treatment for recurrent cancer. The objective response rate (RR) was 26.5% (95% CI: 11.7-41.3) with two complete responses, and stable disease was observed in 41.1% of the patients. Importantly, an RR of 33.3% (95% CI: 0.6-66.0) was achieved for the eight patients who received this regimen as a first-line treatment. The median follow up duration was 14 months for all the patients, and the median time to progression was 6 months (95% CI: 1.9-10.2). The overall survival time was 8.9 months (95% CI: 7.0-11.0) with a 1-year survival rate of 18.7% (95% CI: 5.6-31.8). The most common toxicity was neutropenia. CONCLUSION: PC exhibited promising activity against gastric cancer for the previously untreated patients as a first-line treatment with an acceptable toxicity profile.

While the coronavirus disease 2019 pandemic is ongoing, monkeypox has been rapidly spreading in non-endemic countries since May 2022. Accurate and rapid laboratory tests are essential for identifying and controlling monkeypox. Korean Society for Laboratory Medicine and the Korea Disease Prevention and Control Agency have proposed guidelines for diagnosing monkeypox in clinical laboratories in Korea. These guidelines cover the type of tests, selection of specimens, collection of specimens, diagnostic methods, interpretation of test results, and biosafety. Molecular tests are recommended as confirmatory tests. Skin lesion specimens are recommended for testing in the symptomatic stage, and the collection of both blood and oropharyngeal swabs is recommended in the presymptomatic or prodromal stage.
