Abstract: In the United States, the Emergency Medical Treatment and Active Labor Act (EMTALA) effectively requires Level I trauma centers to accept hand trauma transfers for higher level of care if capacity exists. However, patient transfer for non-medical reasons, such as ability to pay, is still perceived as a common practice. We hypothesized that EMTALA would cause selective transfer of han…
Abstract: Because of the thin skin envelope of the hand, especially at the dorsum, flaps are frequently required for defect reconstruction in the hand. The pedicled radial forearm flap is a time proven procedure that offers reliable coverage in this area without the need of advanced microsurgical expertise. Despite several alternatives and an increasing acceptance of free tissue transfers, the…
Abstract: Ischemia–reperfusion (I/R) injury is, in part, related to the burst of reactive oxygen species (ROS) generated after reperfusion. Vitamin E has been shown to exert its biological effects as an antioxidant, inhibiting the ROS. In this report, the effect of Vitamin E succinate (VES) on ischemia/reperfusion injury and NF-κB expression was studied in a rat skeletal muscle model during…
Abstract: Dupuytren’s disease (DD) is a familial, fibroproliferative, irreversible, and progressive disease of the palmar fascia, yet with unknown etiology. However, there is compelling evidence which has consistently suggested a genetic ethiopathogenesis given the high occurrence among the Northern European extraction, familial nature, and demonstration of concordance in twins. DD is an inc…
