High serum copeptin levels are associated with injury severity after traumatic brain injury (TBI). However, not much is known regarding its relation with mortality. Thus, we sought to evaluate its relation with disease mortality. ⋯ Increased plasma copeptin levels are associated with mortality after TBI.

The purpose of this study was to investigate the amount of fluid required and the sensitivity of the saline load test to identify an intra-articular arthrotomy of the elbow. ⋯ Our results demonstrate that 40 mL of fluid must be injected to identify the majority of traumatic arthrotomies about the elbow. Moreover, adding range of motion after the injection increases the detection rate.

Comparative Study
Controlled blast exposure during forced explosive entry training and mild traumatic brain injury.
There is a paucity of data regarding the pathophysiology and short- and long-term neurologic consequences of primary blast injury in humans. The purpose of this investigation was to test the feasibility of implementing a research protocol in the context of a forced explosive entry training course. ⋯ Studying the effects of blast exposure on the human brain in a controlled experimental setting is not possible. Forced explosive entry training courses afford an opportunity to begin examining this issue in real time in a controlled setting. This study underscores the importance of baseline testing of troops, of the consideration of subclinical implications of blast exposure, and of continued studies of the effects of blast exposures, including repeated exposures on the human brain.

Injuries to pedestrians struck by motor vehicles represent a significant public health hazard in large cities. The purpose of this study is to investigate the demographics of alcohol users who are struck by motor vehicles and to assess the effects of alcohol on pedestrian crossing patterns, medical management, and outcomes. ⋯ Alcohol use is a significant risk factor for pedestrians who are struck by motor vehicles. These patients are more likely to cross the street in an unsafe manner and sustain more serious injuries. Traffic safety and injury prevention programs must address irresponsible alcohol use by pedestrians.

Comparative Study
Targeting pediatric pedestrian injury prevention efforts: teasing the information through spatial analysis.
Pediatric pedestrian injuries remain a major cause of childhood death, hospitalization, and disability. To target injury prevention efforts, it is imperative to identify those children at risk. Racial disparities have been noted in the rates of pediatric pedestrian injury and death. Children from low-income families living in dense, urban residential neighborhoods have a higher risk of sustaining pedestrian injury. Geographic information systems (GIS) analysis of associated community factors such as child population density and median income may offer insights into prevention. ⋯ Spatial analysis using GIS identified associations between pediatric pedestrian motor vehicle crash sites and the neighborhoods served by our pediatric trauma center. Pediatric pedestrian motor vehicle crash sites occurred predominantly within low-income, African-American neighborhoods. The disparity in prevalence of crash sites is somewhat attributable to the lower density of children living in the predominantly higher income, non-African-American neighborhoods, including the community immediately around our hospital. Traffic volume patterns, as a denominator of these injury events, remain to be studied.
