Randomized Controlled Trial
The effect of triage-applied Ottawa Ankle Rules on the length of stay in a Canadian urgent care department: a randomized controlled trial.
To determine whether triage nurses ordering ankle or foot radiographs according to the Ottawa Ankle Rules (OAR) before physician evaluation decreases the length of stay for patients visiting an urgent care department. ⋯ The use of OAR and the ordering of roentgenograms by triage nurses before physician evaluation for twisting ankle or foot injuries does not decrease the length of stay in an urgent care department.

The emergency management of cerebral concussion typically centers on the decision to perform a head computed tomography (CT) scan, which only rarely detects hemorrhagic lesions requiring neurosurgery. The absence of hemorrhage on CT scan often is equated with a lack of brain injury. However, observational studies revealing poor long-term cognitive outcome after concussion suggest that brain injury may be present despite a normal CT scan. ⋯ The authors discuss the strengths and weaknesses of the evidence in each case. These reports make a compelling case for the existence of concussion as a clinically relevant disease with demonstrable neurologic pathology. Areas for future emergency medicine research are suggested.

Comparative Study
The effect of Picture Archiving and Communications Systems on the accuracy of diagnostic interpretation of pediatric emergency physicians.
To compare the accuracy of diagnostic interpretation of radiographs by pediatric emergency physicians (EPs) before and after the introduction of a Picture Archiving and Communications System (PACS). ⋯ Radiograph interpretations by pediatric EPs with digital studies remain as accurate in comparison with assessments performed by using conventional radiographs.

Verapamil is a lipid-soluble calcium channel blocker with significant mortality in overdose. Previous investigators have demonstrated the benefit of lipid emulsion therapy in ameliorating toxicity from lipid-soluble agents. The authors investigated the effect of Intralipid treatment in a rat model of verapamil toxicity. ⋯ Intralipid treatment prolongs survival and doubles median lethal dose in a rat model of verapamil toxicity. The mechanism of action remains to be elucidated.
