Unlike previous studies in an urban environment, this study examines traumatic death in a geographically diverse county in the southwestern United States. ⋯ Although there appears to continue to be a trimodal distribution of trauma deaths in urban environments, we found the distribution to be bimodal in an environment with a higher ratio of blunt to penetrating trauma.

Arterial embolization is a rapid and effective technique for controlling pelvic fracture hemorrhage.
To review the success rate of embolization in stopping hemorrhage for unstable patients with severe pelvic fractures, to calculate the time to achieve embolization, and to determine the yield from angiography. ⋯ Only a small percentage of patients with pelvic fractures require embolization, but when it is used, embolization can be 100% effective. Age, time to achieve embolization, and initial hemodynamic instability appear to be important factors in survival.

Comparative Study
Value of thoracic computed tomography in the first assessment of severely injured patients with blunt chest trauma: results of a prospective study.
The aim of this prospective study was to evaluate whether early thoracic computed tomography (TCT) is superior to routine chest x-ray (CXR) in the diagnostic work-up of blunt thoracic trauma and whether the additional information influences subsequent therapeutic decisions on the early management of severely injured patients. ⋯ TCT is highly sensitive in detecting thoracic injuries after blunt chest trauma and is superior to routine CXR in visualzing lung contusions, pneumothorax, and hemothorax. Early TCT influences therapeutic management in a significant number of patients. We therefore recommend TCT in the initial diagnostic work-up of patients with multiple injuries and with suspected chest trauma because early and exact diagnosis of all thoracic injuries along with sufficient therapeutic consequences may reduce complications and improve outcome of severely injured patients with blunt chest trauma.

Comparative Study
Analysis of cellular and decellular allogeneic dermal grafts for the treatment of full-thickness wounds in a porcine model.
The need for a reliable skin substitute to improve burn treatment has been long apparent. We have investigated the use of cryopreserved cellular and decellularized porcine allogeneic dermal grafts (CADGs or DADGs) in conjunction with an overlying thin split-thickness autograft (STSG) in a one-step technique. Control mirror-image wounds were treated with thin STSG alone. Autograft "take" rates and wound contraction were determined; biopsies were taken at weeks 2, 5, and 8, and blinded scar assessment was performed at week 10. ⋯ CADGs and DADGs permitted simultaneous engraftment of an overlying thin STSG. Although CADGs had no effect on wound contraction and cosmetic outcome, DADGs significantly reduced wound contraction and improved cosmetic outcome of full-thickness wounds in a porcine model. The use of DADGs may represent a potential improvement in burn care.
