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.

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.

Comparison of trauma survival rates between institutions and reference data bases is hampered by different injury severity mixes. To overcome this, a standardized comparison using a stratified W statistic (Ws) has been proposed. Ws enables comparisons but does not represent actual survival rates at an institution. ⋯ Ws is useful for comparison between centers. Trauma and Injury Severity Score methodology overpredicts survival in certain probability of survival intervals. Adjustment can be made to estimate the actual survival rate. When applied to an integrated trauma system, such adjustments demonstrate overall improved survival, most noticeable in a more severely injured subgroup.

Many new types of expanding or fragmenting handgun ammunition have been developed. Knowledge of these unusual bullets may aid in the management of patients and their wounds. ⋯ Expanding/fragmenting bullets produce larger, shallower wounds than do full metal jacketed bullets. Recognition of the wound and roentgenographic appearances of these unusual bullets will help the trauma surgeon to properly treat gunshot victims. Because of the occurrence of jacket separation in water, ordnance gelatin should be used for optimal evaluation of bullet performance.
