Immunoglobulin G4-Related Inflammatory Pseudotumor Presenting as a Solitary Mass in the Stomach.

Immunoglobulin G4 (IgG4)-related disease (IgG4RD) is a relatively recently recognized entity that is histopathologically characterized by an extensive infiltration of lymphocytes and IgG4-positive plasma cells with dense fibrosis. IgG4RD is now known to affect any organ system, and a few cases of gastrointestinal lesions have also been reported. However, solitary IgG4RD of the stomach is still very rare.

[Prognostic factors in patients with advanced pancreatic cancer treated with gemcitabine chemotherapy: clinical characteristics of long-term survivors].

Background/aims: Gemcitabine-based chemotherapy has been used as a standard treatment in patients with unresectable pancreatic cancer. However, the clinical outcomes of this regimen are still unsatisfactory in prolonging survival. We retrospectively analyzed clinical characteristics of patients with advanced pancreatic cancers who received gemcitabine-based chemotherapy and showed long-term survival.

Comparison of infarct-related artery vs multivessel revascularization in ST-segment elevation myocardial infarction with multivessel disease: analysis from Korea Acute Myocardial Infarction Registry.

Background: Many ST-segment elevation myocardial infarction (STEMI) patients have multivessel disease. There is still controversy in treatment strategy in STEMI patients with multivessel disease. We compared clinical outcomes of multivessel revascularization with infarct- related artery (IRA) revascularization in STEMI patients.

Safety and effect of adipose tissue-derived stem cell implantation in patients with critical limb ischemia: a pilot study.

Background: Treatment of critical limb ischemia (CLI) by bypass operation or percutaneous vascular intervention is occasionally difficult. The safety and efficacy of multiple intramuscular adipose tissue-derived mesenchymal stem cells (ATMSC) injections in CLI patients was determined in the study.

Methods And Results: The study included 15 male CLI patients with ischemic resting pain in 1 limb with/without non-healing ulcers and necrotic foot.

Effect of intra-coronary nicorandil administration prior to reperfusion in acute ST segment elevation myocardial infarction.

Background: Intravenous nicorandil infusion with percutaneous coronary intervention (PCI) has been reported to reduce reperfusion injury events and improve cardiac function in patients with acute myocardial infarction (MI). However, there is limited information on the use of intracoronary nicorandil.

Methods And Results: In the present study, 73 patients with acute ST segment elevation MI undergoing PCI were randomly assigned to the Nicorandil Group (n=37) or the Control Group (n=36).
