Severe sepsis and septic shock are potentially deadly conditions managed in the emergency department (ED). Management centers on source control, fluid resuscitation, broad-spectrum antimicrobials, and vasopressors as needed. The use of corticosteroids is controversial. ⋯ Septic shock is associated with higher mortality, specifically for patients with vasopressor and fluid-refractory shock. The use of physiologic-dose steroids can reduce vasopressor requirements and improve time of shock resolution. Current literature suggests corticosteroids do not improve mortality, but further studies are required.

Case Reports
Spontaneous Subclavian Artery Dissection Causing Ischemia of the Medulla Oblongata and Cerebellum.
Spontaneous subclavian artery dissection is a rare etiology. Spontaneous artery dissection causing brain ischemia is rare in all ischemic strokes. However, in young to middle-aged patients with brain ischemia, spontaneous carotid or vertebral artery dissection causing ischemic stroke accounts for 10-25%. ⋯ A 58-year-old man with a history of hypertension presented to the Emergency Department with a sudden onset of left-arm paresthesia and numbness followed by symptoms of vertigo and vomiting. A neurological examination showed left-arm paresthesia, horizontal-rotational nystagmus, and left-side dysmetria according to a finger-to-nose test. Contrast-enhanced computed tomography showed left subclavian artery dissection. Diffusion-weighted imaging demonstrated hyperintensity in the left medulla oblongata and inferior part of the cerebellum. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Spontaneous artery dissection is an important etiology of ischemic stroke among young patients. Cervical magnetic resonance angiography is the gold standard for the diagnosis of arterial dissection. Cervical disc disease is a common etiology in a patient with neck and shoulder pain without cause or neurologic symptoms, when cervical MRI is negative, however, spontaneous subclavian artery dissection should be considered in the differential diagnosis when a patient, especially in a case of younger patient, presents with acute new-onset neck and shoulder pain followed by the onset of neurological symptoms.

Case Reports
Intractable Nausea Due to the Area Postrema Syndrome of Neuromyelitis Optica: An Uncommon Cause of a Common Symptom.
Nausea and vomiting are common emergency department (ED) complaints. Neuromyelitis optica, a demyelinating disorder, has a predilection for the area postrema, the central nausea and vomiting center. Demyelinating lesions in this region cause intractable nausea and vomiting. ⋯ We present a case of area postrema syndrome due to neuromyelitis optica in a 34-year-old woman who was seen in several EDs before the appropriate diagnosis was made. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Nausea and vomiting are complaints that commonly bring people to the ED, thus, emergency physicians are likely to be the first to encounter and diagnose the area postrema syndrome.

Studies have shown that patient understanding and recall of their emergency department (ED) discharge instructions is limited. The teach-back method involves patients repeating back what they understand, in their own words, so that discharge providers can confirm comprehension and correct misunderstandings. ⋯ The teach-back method had a positive association on retention of discharge instructions in the ED regardless of age and education.
