ReviewDiagnosis and management of the primary headache disorders in the emergency department setting.
Headache continues to be a frequent cause of emergency department (ED) use, accounting for 2% of all visits. Most of these headaches prove to be benign but painful exacerbations of chronic headache disorders, such as migraine, tension-type, and cluster. ⋯ Although these headaches have distinct epidemiologies and clinical phenotypes, there is overlapping response to therapy; nonsteroidals, triptans, dihydroergotamine, and the antiemetic dopamine antagonists may play a therapeutic role for each of these acute headaches. This article reviews the diagnostic criteria and management strategies for the primary headache disorders.

ReviewEmergency treatment of status epilepticus: current thinking.
Current thinking about the acute treatment of status epilepticus (SE) emphasizes a more aggressive clinical approach to this common life-threatening neurologic emergency. In this review, the authors consider four concepts that can accelerate effective treatment of SE. These include (1) updating the definition of SE to make it more clinically relevant, (2) consideration of faster ways to initiate first-line benzodiazepine therapy in the prehospital environment, (3) moving to second-line agents more quickly in refractory status in the emergency department, and (4) increasing detection and treatment of unrecognized nonconvulsive SE in comatose neurologic emergency patients.

ReviewEnhancing community delivery of tissue plasminogen activator in stroke through community-academic collaborative clinical knowledge translation.
Improving the clinical outcomes of stroke patients depends on the adoption of proven new therapies throughout the broader medical community. Approximately 1% of stroke patients in community settings are receiving tissue plasminogen activator (tPA) therapy 12 years after US Food and Drug Administration approval. ⋯ This article reviews the history of tPA use in stroke as a case study of a breakdown of knowledge translation in emergency medicine. It reviews knowledge translation concepts and theory and explores practical community-academic collaborative methods based on these tenets to enhance acute stroke care delivery in the community setting.

Understanding three peripheral vestibular disorders--vestibular neuritis, benign paroxysmal positional vertigo, and Meniere's disease--is the key to the evaluation and management of vertigo and dizziness presentations in the emergency department. Each of these benign disorders is a common cause of a broad category of dizziness presentation. ⋯ An effective strategy for "ruling-out" a serious disorder, such as stroke, is "ruling-in" a peripheral vestibular disorder. In this article a focus is on the key features of these disorders.

This review briefly discusses induced therapeutic hypothermia (TH), which represents the intentional induction of a lowered core body temperature of 35 degrees C or less. The focus is on resuscitative or postarrest hypothermia, the data that support it, and the practical issues pertaining to TH implementation.
