Gastric schwannoma: a rare but important differential diagnosis of a gastric submucosal mass.

Schwannomas are generally slow growing asymptomatic neoplasms that rarely occur in the GI tract. However, if found, the most common site is the stomach. Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, and 60-70% of them occur in the stomach.

Modified two-stage basilic vein transposition for hemodialysis access.

Background: Various techniques for basilic vein transposition have been described, including endovascular, 1-stage, and 2-stage transposition. However, none of these 2-stage techniques include a new arteriovenous anastomosis during the second stage. This study adds to the current literature as well as introducing a new and innovative technique for hemodialysis access.

Evidence-based medicine guidelines in obstetrics/gynecology and trauma surgery.

The purpose of this study was to compare the use of evidence based medicine in the guidelines published by the American College of Obstetrician and Gynecologists (ACOG) and Trauma Surgery (Eastern Association for Trauma Surgery [East]). We compared the references and the types of recommendations in ACOG and EAST guidelines. Odds ratio (OR), along with 95% confidence intervals (CI) were calculated and 95% CI not crossing the integer 1 were considered significant.
