Ideal tongue reconstruction after partial or total glossectomy should be accomplished with like tissue. The buccinator musculomucosal island flap is similar to lingual tissue, consisting of thin, pliable mucosa of mucus production, with high cell renewal rate and minimal scar formation, excellent color, contour, texture match, and buccinator muscle fibers over the flap's entire length, providing tongual muscle reconstruction without a conspicuous donor site. ⋯ The buccal musculomucosal island flap based on the facial artery and vein is a better reconstruction option with the same or similar kind of tissue as the tongue and, with the addition of the reinnervated flap, offers the potential for improved physiologic motion.

Acute limb ischemia initiates a systemic inflammatory response, including pulmonary polymorphonuclear leukocyte (PMN) sequestration and acute lung injury. Lung injury is partly attributed to release by PMN's of extracellular matrix (ECM) modifying metalloproteinases (MMPs). We hypothesized that acute hindlimb ischemia (HI) would increase MMP activity in the lung and other organs and that systemic neutrophil depletion before HI would block this effect. ⋯ HI increases pulmonary proMMP-9, active MMP-9, and active MMP-2 levels. Neutrophil depletion blocks this effect. These data suggest that acute limb ischemia leads to PMN-mediated changes in MMP activity.

Recombinant Factor VIIa (rFVIIa) has been used to decrease bleeding in a number of settings, including hemophilia, liver transplantation, intractable bleeding, and cirrhosis. It has also been shown to reduce bleeding in coagulopathic pigs with Grade V liver injuries when used as an adjunct to packing. This study was performed to determine if rFVIIa would reduce blood loss after a Grade V liver injury in noncoagulopathic pigs when used as sole therapy. ⋯ rFVIIa does not reduce blood loss after Grade V liver injury when it is used as sole therapy in warm noncoagulopathic pigs.

Data on the relative clinical and economic impact of postoperative complications are needed in order to direct quality improvement efforts. ⋯ Complications are independently associated with increased resource use after high-risk surgery. Population-based studies may be valuable in determining the relative economic importance of postoperative complications. Quality improvement efforts for these complications should be prioritized based on both the incidence of the complication and its independent contribution to increased resource use.
