BACKGROUND: Although current guidelines do not recommend immediate anticoagulation therapy (IAC) for acute ischemic stroke, judicious debates are still lingering on whether it might be done for acute cardioembolic stroke (ACES). We surveyed current practice patterns of anticoagulation therapy for ACES in Korea, and analyzed their related factors. METHODS: Using a web-based system, all neurology staffs of training hospitals in Korea surveyed about when and how they commenced anticoagulation therapy in the hypothetical cases with ACES. RESULTS: Of the 359 subjects invited, 281 responded to the e-mail, of whom 76 abstained from participating. The number of participants was therefore 205 (57.1%). Although a few physicians (4.4%) always performed IAC and some (10.7%) never did, most physicians made different decisions according to infarct size and presence of hemorrhagic transformation (HTr): IAC was performed more often in cases with medium-sized or small infarct than large one (68.2% vs. 35.9%, P<0.001), and in cases without HTr (68.6% vs. 34.9%, P<0.001). The most common method of administration was 'heparin followed by warfarin' (68.2%), and then 'warfarin alone' or 'warfarin with aspirin'. If IAC was not commenced, it resumed most commonly between 1 and 2 weeks after the onset (44.0%). CONCLUSION: Quite many neurologists in Korea did IAC in selective ACES, e.g. small sized infarction without HTr. Further studies are needed to prove the efficacy of IAC therapy in this selective population.

Terlipressin, a vasopressin agonist, is widely used to treat variceal bleeding and hepatorenal syndrome in patients with liver cirrhosis. Terlipressin increases systemic vascular resistance, particularly in the splanchnic area, thus decreasing portal pressure. Although terlipressin is associated with a lower incidence of severe cardiovascular complications than is vasopressin, terlipressin can induce serious ischemic complications including myocardial infarction, skin necrosis, and bowel ischemia in < 1% of patients. We report the case of a 79-year-old female with liver cirrhosis treated with terlipressin to control hepatorenal syndrome that developed into ischemic colitis. The patient improved upon cessation of terlipressin and provision of supportive care.

A 57-year-old man with chronic kidney disease and a history of using numerous herbal medications visited Inje University Ilsan Paik Hospital for abdominal pain and vomiting. An abdominal radiograph showed diffuse small bowel distension containing multiple air-fluid levels and extensive calcifications along the colon. Computed tomography showed colon wall thickening with diffuse calcification along the colonic mesenteric vein and colonic wall. Colonoscopy, performed without bowel preparation, showed bluish edematous mucosa from the transverse to the distal sigmoid colon, with multiple scar changes. At the mid transverse colon, a stricture was noted and the scope could not pass through. A biopsy of the stricture site revealed nonspecific changes. The patient was diagnosed with phlebosclerotic colitis. After the colonoscopy, the obstructive ileus spontaneously resolved, and the patient was discharged without an operation. Currently, after 2 months of follow-up, the patient has remained asymptomatic. Herein, we report the rare case of an obstructive ileus caused by phlebosclerotic colitis with a colon stricture.

The development of gastric cancer (GC) is closely related to chronic inflammation caused by Helicobacter pylori infection, and herpes virus entry mediator (HVEM) is a receptor expressed on the surface of leukocytes that mediates potent inflammatory responses in animal models. However, the role of HVEM in human GC has not been studied. Previously, we showed that the interaction of HVEM on human leukocytes with its ligand LIGHT induces intracellular calcium mobilization, which results in inflammatory responses including induction of proinflammatory cytokine production and anti-bacterial activities. In this study, we report that leukocytes from GC patients express lower levels of membrane HVEM (mHVEM) and have lower LIGHT-induced bactericidal activities than those from healthy controls (HC). In contrast, levels of soluble HVEM (sHVEM) in the sera of GC patients were significantly higher than in those of HC. We found that monocyte membrane-bound HVEM is released into the medium when cells are activated by proinflammatory cytokines such as TNF-alpha and IL-8, which are elevated in the sera of GC patients. mHVEM level dropped in parallel with the release of sHVEM, and release was completely blocked by the metalloprotease inhibitor, GM6001. We also found that the low level of mHVEM on GC patient leukocytes was correlated with low LIGHT-induced bactericidal activities against H. pylori and S. aureus and production of reactive oxygen species. Our results indicate that mHVEM on leukocytes and sHVEM in sera may contribute to the development and/or progression of GC.

Coronary pseudo-lesion is an artificial lesion that occurs during percutaneous transluminal coronary angioplasty by an angioplasty guide wire and/or a balloon as a result of a straightening of the vessel curvature. A specific treatment is not required and the condition is completely resolved after removing the angioplasty wire. There are few reports about a pseudo-lesion, particularly in the left circumflex artery. We report two cases of a coronary pseudo-lesion induced by an angioplasty guide wire; one case affecting the left circumflex artery and the other affecting the right coronary artery.
