Blast injuries in the United States and worldwide are not uncommon. Partially due to the increasing frequency of both domestic and international terrorist bombing attacks, it is prudent for all emergency physicians to be knowledgeable about blasts and the spectrum of associated injuries. ⋯ Blast events can produce a myriad of injuries affecting any and every body system. All emergency physicians should be familiar with the presentation and management of these injuries. This knowledge may also be incorporated into triage and discharge protocols guiding management of mass casualty events.

Patients taking antiplatelet agents (APAs) with intracranial hemorrhage (ICH) may be treated with platelet transfusion. ⋯ The evidence for platelet transfusion in APA-related ICH was inconclusive due to methodological limitations.

Headaches are common in the pediatric population, and increase in prevalence with age. The abortive medications currently used have a number of potential side effects. Sodium valproate (VPA) has been shown to be effective for acute treatment in the adult population, but no data exist in the pediatric population. ⋯ VPA appears to be an effective agent for acute pediatric headache in this small series. Patients responded well to VPA in a relatively short amount of time. Further studies are needed to evaluate its effectiveness in combination with other first-line medications or as a single agent.

Although there are no clinical decision rules for radiograph use among persons with shoulder pain, they are ordered for most patients. Previously published reviews have demonstrated that radiography is overutilized in evaluating emergency department (ED) patients with shoulder pain, and clinical factors might define patients in whom plain film radiography need not be performed. ⋯ Despite accounting for multiple variables, the area under the curve was 80%. Based on these results it is not practical to develop clinical decision radiograph ordering rules for ED patients with shoulder pain.

Intubation in hypotensive emergency department (ED) patients may increase the risk of life-threatening complications such as hypoperfusion and cardiovascular collapse. Peripherally administered, diluted "push-dose" phenylephrine has been advocated to treat peri-intubation hypotension, however, its effectiveness is unknown. ⋯ In this academic ED, bolus-dose phenylephrine was used by practitioners without a systematic pattern. Although phenylephrine improved hemodynamics, it is possible that nonsystematic use of phenylephrine may cause inadvertent negative effects. Further studies will need to be conducted to better understand the best practices for use of phenylephrine.
