The mesenteric infarction is a rare but life threatening cause of acute abdomen. A 55-year-old woman was referred to the hospital because of acute mesenteric infarction and in the history claudication. ⋯ The patient is now receiving low-dose aspirin and anticoagulation therapy. The follow-up over now 14 months shows no further events.

Intestinal ischemia, frequently found in clinical states such as aortic bypass operations or hemorrhagic shock, is associated with loss of gut barrier function. Subsequent translocation of indigenous bacteria and endotoxin have been implicated as a major contributor to a systemic immuno-inflammatory response, which finally leads to multiple organ failure. There is increasing evidence that intestinal injury can result in the gut becoming a cytokine generating organ. This study was designed to show direct evidence of the gut as a major source of proinflammatory cytokines after intestinal ischemia and to further relate this cytokine response to the extent of intestinal ischemia/reperfusion. Additionally the potential role of the altered intestinal barrier function after intestinal ischemia for this cytokine response was investigated. ⋯ The gut becomes a cytokine liberating organ alter intestinal ischemia/reperfusion. This cytokine response is affected by certain conditions, but is not directly related to an impaired intestinal barrier function.

In patients with progressive systemic sclerosis (PSS) suffering from chronic dyspepsia the stomach may be affected by this disease. The objective of this study was to investigate both antral myoelectrical activity and gastric emptying in PSS patients. Electrogastrography (EGG) was performed in 17 PSS patients (16 female, one male, median age 58 years, range 32-74 years) with chronic dyspepsia. ⋯ However, EGG did not correlate to radioscintigraphy significantly. Our results reflect an absent relationship between antral myoelectrical activity in EGG and gastric emptying. Therefore, electrogastrography is unsuitable to assess gastric involvement in PSS.

Comment Meta Analysis Comparative Study
[Are proton pump inhibitors superior to H2 receptor antagonists within the scope of H. pylori eradication therapy? Meta analysis of current parallel group comparisons].
The combined treatment with acid lowering drugs and antibiotics is widely accepted for H. pylori-eradication therapy. There are, however, controversies regarding the influence of the acid lowering drug on H. pylori-eradication rates. Therefore, this meta-analysis aimed to assess the available parallel-group eradication studies with proton pump inhibitors and H2-receptor antagonists and to compare H. pylori-eradication rates for both classes of acid lowering drugs. ⋯ CONCLUSION. H. pylori-eradication rates for treatment protocols with one or two antibiotics in combination with an acid lowering drug are not different for the proton pump inhibitors or h2-receptor antagonists. Therefore, the question whether H2-receptor antagonists or proton pump inhibitors should be used in combination with antibiotics for H. pylori eradication therapy is without clinical relevance.
