To assess the need for cranial computed tomography (CT) in the emergency department evaluation of children with Glasgow Coma Scale (GCS) score of 15 after mild head injury with loss of consciousness. ⋯ The prevalence of intracranial hemorrhage in children with mild closed-head injury appears to vary with the presence of neurologic abnormalities and other noncranial injuries. After isolated head injury with loss of consciousness, children older than 2 years who are neurologically normal and without signs of depressed or basilar skull fracture may be discharged home from the ED without a cranial CT scan after careful physical examination alone.

Femoral artery injuries can be predicted by the mechanism of injury, wound location and tract, and physical findings following penetrating thigh trauma. ⋯ Only patients with medial thigh wounds need to undergo angiography for the detection of femoral artery injuries. This approach would have reduced the angiography rate by 36% in this series. Had angiography been performed only on patients with any physical findings, a 70% reduction in the rate of angiography would have been achieved, although five occult arterial injuries per year would have been missed. Angiography should not be performed solely because of a gunshot mechanism or the presence of a femur fracture.

To analyze a standardized medical evaluation of alert, adult emergency department patients with new psychiatric symptoms. ⋯ Most alert, adult patients with new psychiatric symptoms have an organic etiology. We recommend performing a medical history, physical examination, SMA-7, calcium, CPK if there is possible myoglobinuria, alcohol and drug screens, computed tomography scan, and lumbar puncture as part of the medical clearance of these patients.

Adenosine is an efficacious diagnostic and therapeutic agent in the acute management of wide complex tachycardias. Its potent negative dromotropic effect terminates supraventricular tachycardias involving the atrioventricular node, allowing differentiation from tachycardias of atrial and ventricular origin. ⋯ One patient had idiopathic ventricular tachycardia originating from the right ventricular outflow tract, one had ectopic atrial tachycardia, and one had atrial fibrillation with rate-related intraventricular aberration. Recognition of the extranodal actions of adenosine and careful ECG evaluation before and after adenosine administration should maximize the diagnostic accuracy of adenosine in wide complex tachycardias.
