Many cases of acute human immunodeficiency virus (HIV) infection (AHI) present to the Emergency Department (ED). Early diagnosis allows a patient to modify their behavior and seek early treatment. The Emergency Physician should know that the antibody response may be absent. ⋯ This case illustrates that AHI can present as a non-specific illness. Patients at risk should be screened for HIV. However, AHI can occur before there is a significant antibody response. In such cases, a viral load test may help make the diagnosis, allowing for early treatment and patient counseling.

Although cardiac risk prediction is widely used in various clinical settings, its potential role in enhancing prehospital triage is yet to be understood. ⋯ The models identified provided reasonable diagnostic accuracy for determining short-term outcomes. Methodological weaknesses and variability in the populations investigated limit their use in clinical practice.

Prehospital electrocardiography (PH ECG) is becoming the standard of care for patients activating Emergency Medical Services for symptoms of acute coronary syndrome (ACS). Little is known about the prognostic value of ischemia found on PH ECG. ⋯ Evidence of ischemia on PH ECG is an independent predictor of adverse hospital outcomes. ST-segment monitoring in the prehospital setting can identify high-risk patients with symptoms of ACS and provide important prognostic information at presentation to the Emergency Department.
