Thermal Imaging Facilitates Design of a Keystone Perforator Island Flap for a Myxofibrosarcoma Resection Reconstruction: Case Report.

Lower extremity defects are challenging to reconstruct. The keystone perforator island flap proves useful in difficult cases. Traditionally, a handheld Doppler is used to confirm perforator vessel(s) within the flap but has disadvantages including low sensitivity/specificity.

Prophylactic fasciotomy in a porcine model of extremity trauma.

Background: Extremity injury, with concomitant hemorrhagic shock, can result in ischemia-reperfusion injury and the formation of compartment syndrome requiring fasciotomy. As the benefit of prophylactic fasciotomy is unclear, the objective of this study is to determine the functional recovery of an ischemic limb with hemorrhagic shock after prophylactic fasciotomy.

Material And Methods: Yorkshire swine underwent 35% blood volume hemorrhage, followed by 1, 3, and 6 h of ischemia (n = 17; 1HR, 3HR, and 6HR) via iliac artery occlusion followed by repair and reperfusion.

Interpreting comparative died of wounds rates as a quality benchmark of combat casualty care.

Background: The died of wounds (DOW) rate is cited as a measure of combat casualty care effectiveness without the context of injury severity or insight into lethality of the battlefield. The objective of this study was to characterize injury severity and other factors related to variations in the DOW rate.

Methods: The highest monthly DOW (HDOW) and lowest monthly DOW (LDOW) rates from 2004 to 2008 were identified from analysis and casualty report databases and used to direct a search of the Joint Theater Trauma Registry.

Microvascular porcine model for the optimization of vascularized composite tissue transplantation.

Background: Devastating extremity injuries are prevalent but most often survivable on the modern battlefield. The complexity of these injuries requires advanced methods of reconstruction. This study is designed to validate the feasibility of gracilis myocutaneous flap transplantation via microvascular free tissue transfer in a porcine model.

Progressive reduction in central blood volume is not detected by sublingual capnography.

Early detection and management of shock are important in optimizing clinical outcomes. One regional marker, sublingual capnography (SLCO2), is particularly appealing as redistribution of blood flow away from the sublingual mucosa can happen very early in the compensatory phase of hypovolemic shock. Our objective was to test the hypothesis that SLCO2 would detect early hypovolemia in a human laboratory model of hemorrhage: progressive lower body negative pressure until onset of cardiovascular collapse.

Attitudes toward predeployment and experimental vaccinations among troops deployed to Operation Iraqi Freedom and Operation Enduring Freedom.

Background: The Department of Defense is actively engaged in the research and development of vaccine(s) to mitigate the burden of disease associated with diarrhea among deployed troops. Soldiers' attitudes and beliefs toward predeployment vaccines and participation in experimental research with vaccines are unknown.

Methods: To assess these attitudes, a survey was distributed among soldiers who had been and were currently deployed to Operations Iraqi and Enduring Freedom.
