Laparoscopic resection of a torsioned appendix epiploica in a previously appendectomized patient.

Torsion of the appendices epiploicae is a rare condition that may present with acute abdominal pain and mimics appendicitis. We report a 20-year-old previously appendectomized man presenting with right lower abdominal quadrant pain. Abdominal ultrasonography showed a localized omental thickening in the right paracolic region.

Beneficial effects of N-acetylcysteine on sodium taurocholate-induced pancreatitis in rats.

Background: Acute pancreatitis (AP) is a complex disease associated with significant complications and a high rate of mortality. Although several mechanisms are put forward, oxidative stress seems the most important early event in the pathophysiology of AP. Therefore, we evaluated the beneficial effects of N-acetylcysteine (NAC), a strong antioxidant, in experimental AP.
