Peritoneal injury sustained at laparotomy may evoke local inflammatory responses that result in adhesion formation. Peritoneal mast cells are likely to initiate this process, whereas vascular permeability/endothelial growth factor (VEGF) may facilitate the degree to which subsequent adhesion formation occurs. ⋯ Mast cells and VEGF are central to the formation of postoperative intra-abdominal adhesions with mast cells being responsible, either directly or indirectly, for VEGF release into the peritoneal cavity after operation. In tandem with the recent clinical success of anti-VEGF monoclonal antibodies in oncologic practice, our observations suggest an intriguing avenue for research and development of anti-adhesion strategy.

The aim of this prospective study was to determine whether the change between the initial and subsequent analysis of serum inflammatory markers measured 6 to 10 hours later could improve diagnostic accuracy in appendicitis. ⋯ The cutoff values of the change in total neutrophil count on the first day after onset of symptoms and the change in CRP on the second and third days after onset of symptoms during in-hospital observation may serve as useful parameters to surgeons in differentiating acute appendicitis from other acute abdominal diseases.

Selective beta adrenergic antagonists are commonly used to reduce myocardial demise in patients at risk for cardiac-related death. The purpose of this study was to examine the hemodynamic and metabolic effects of cardiac selective beta adrenergic blockade in patients. ⋯ Cardiac selective beta adrenergic blockade with esmolol reduces cardiac output in proportion to the percentage decreases in heart rate in moderately severe septic patients without adversely affecting oxygen utilization or hepatic, peripheral blood flow.
