Multicenter Study
National survey of emergency physicians for transient ischemic attack (TIA) risk stratification consensus and appropriate treatment for a given level of risk.
Five percent of transient ischemic attack (TIA) patients have a subsequent stroke within 7 days. The Canadian TIA Score uses clinical findings to calculate the subsequent stroke risk within 7 days. Our objectives were to assess 1) anticipated use; 2) component face validity; 3) risk strata for stroke within 7 days; and 4) actions required, for a given risk for subsequent stroke. ⋯ A validated Canadian TIA Score will likely be used by emergency physicians. Most components of the TIA Score have high face validity. Risk strata are definable, which may allow physicians to determine immediate actions, based on subsequent stroke risk, in the emergency department.

Case Reports
Massive cerebral air embolism after blunt chest trauma with full neurological recovery.
Cerebral air embolism (CAE) is a common, often lethal, complication in blunt and penetrating chest trauma. The factors affecting the outcome of CAE patients are poorly understood, and there is no generally accepted treatment algorithm. ⋯ With prehospital intubation, oxygen, transfusion, and open laparotomy but without any specific treatment regarding the CAE, a follow-up computed tomography (CT) scan approximately 6 hours later showed resolution of the cerebrovascular air. Recovery was unremarkable, and the patient was discharged neurologically intact after 22 days.
