To identify risk factors for fractures associated with an anterior shoulder dislocation treated in an emergency department (ED). ⋯ Three risk factors predict clinically important fractures that are associated with shoulder dislocation: age, first episode, and mechanism of dislocation. A prospective validation may lead to standardized use of prereduction radiographs of the shoulder in the ED.

The Society for Academic Emergency Medicine (SAEM) surveyed the Council of Academic Societies (CAS) organizations to obtain useful information to project SAEM goals into the year 2010. The objective of this work was to understand common and varying organizational operations and identify opportunities. ⋯ The survey methodology was used to gain insight into modes of operation of CAS organizations and enable SAEM to review its own operations and identify potential organizational changes based on the experiences of others. Individual CAS organizations might similarly benefit by reviewing the results of the survey and comparing themselves with others.

Comparative Study
Multiple episodes of mild traumatic brain injury result in impaired cognitive performance in mice.
Results from recent studies on animal models of concussion suggest that multiple, rather than single, episodes of mild traumatic brain injury result in impaired cognitive performance in mice. The objective of the present study was to administer multiple impacts to the heads of mice while directly measuring the force of the impacts to determine how these parameters are related to transient loss of consciousness, cognitive deficits, and potential neuropathologic effects. ⋯ This multiple-impact model, delivered within a specifiable force range, results in transient, reversible loss of consciousness, a contra-coup brain injury, and cognitive impairment.
