Environmental exposure to high temperatures can result in abnormalities ranging from mild heat exhaustion to heat stroke with multiorgan system failure. An understanding of the mechanisms of thermoregulation and how those mechanisms fail with extreme heat stress is critical for management of the patient with elevated body temperature in the emergency department.

ReviewFever and the rational use of antimicrobials in the emergency department.
Any patient presenting to the emergency department (ED) with fever triggers consideration of the administration of an antimicrobial. Empiric antimicrobial therapy has become a cornerstone of treatment. ⋯ This article aims to provide a systems-based approach to prescribing antimicrobials to patients presenting to the ED with fever, while understanding the risk associated with overutilization.

Neurologic conditions are categorized as either those that cause a change in mental status or those that create a focal finding on physical examination. Neurologic abnormality associated with fever can be caused by a primary neurologic condition or one that does not originate in the central nervous system. Optimal management of such conditions requires high clinical suspicion and a broad differential diagnosis, which facilitates rapid recognition and effective treatment. A thorough history and physical examination are key determinants in accurately diagnosing neurologic conditions associated with fever, often requiring acquisition of collateral information from persons other than the patient.
