Ingestion of cylindrical batteries is uncommon. Management can include removal via upper endoscopy, surgical excision, or observation. This case demonstrates the rare phenomenon of cylindrical battery ingestion causing an electrocardiogram (ECG) artifact that mimics ST segment myocardial infarction (STEMI). ⋯ A 51-year-old man who ingested 13 small pencils and 18 AA batteries was found to have ST segment elevation in the inferior leads of the ECG. Further cardiac workup including cardiac biomarkers and transthoracic echocardiogram was negative, and his ECG changes resolved after extraction of the batteries. The ST segment changes were most likely caused by electrical artifact from battery ingestion. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: When faced with an ECG finding that is unexpected and that does not fit the patient's overall clinical picture, emergency physicians should consider artifact as a possible cause. Recognition of artifact as the cause of an ECG abnormality can obviate the need for a prolonged and potentially invasive cardiac workup.

Discharge against medical advice (AMA) is an important, yet understudied, aspect of health care-particularly in trauma populations. AMA discharges result in increased mortality, increased readmission rates, and higher health care costs. ⋯ Insurance status, race, and ethnicity are associated with a patient's decision to leave AMA. Uninsured and Medicaid patients have more than twice the odds of leaving AMA. These findings demonstrate that racial and socioeconomic disparities are important targets for future efforts to reduce AMA rates and improve outcomes from blunt and penetrating trauma.

Acute or recurrent hip pain in adults can be a challenging presentation in the emergency department. While ultrasound is routinely used in the evaluation of pediatric patients with hip pain and a new limp, it is not commonly used for this purpose in adult emergency medicine. This case series demonstrates the clinical utility of point-of-care ultrasound (POCUS) in adult patients with acute or recurrent hip pain because performance of POCUS was the critical action that led to the identification of pathologic hip effusions in this series of adults. ⋯ This case series includes 5 patients in whom clinical suspicion existed for the presence of a hip effusion and possible septic arthritis, despite nondiagnostic radiographic findings. Ultrasound was used to detect the effusion and guide subsequent arthrocentesis, imaging, or surgical intervention. In all patients, computed tomography scans or magnetic resonance imaging scans were later used to confirm the presence of effusion. In all 5 patients (2 women and 3 men, with a mean age of 47.4 years), POCUS accurately detected the presence of hip effusion. Two of 5 synovial collections were caused by septic arthritis as confirmed by synovial fluid microbiologic examination. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case series emphasizes the clinical utility of POCUS in adult patients with acute and recurrent hip pain to detect a hip effusion, particularly in patients with significant risk factors for septic arthritis. POCUS can also be used to guide further imaging, arthrocentesis, surgical consultation, and intervention.

Inhaled β-agonists are the cornerstone of acute treatment for asthma and chronic lung disease. Upon emergency department (ED) discharge, patients optimally receive prescriptions for metered-dose inhalers (MDIs) with instructions on their proper use. Yet prior studies suggest that ED personnel have limited knowledge of proper MDI techniques. It is unclear how effectively brief education will improve this knowledge to enable them to provide adequate patient instructions. ⋯ This study demonstrated both that ED personnel had poor initial knowledge about MDI techniques and that a brief educational intervention improved most people's ability to use, and presumably to instruct patients/parents in proper use of, MDIs.

Acute aortic dissection is the most common life-threatening disorder affecting the aorta, and can mimic other disease processes. We describe an unusual presentation of a critically ill patient with initial hematospermia diagnosed with a type A acute aortic dissection. ⋯ A 68 year old man presented to a community ED after masturbation and report of blood in his ejaculate, followed by rapid development of severe low back, chest and hip pain with shock. ECG showed evidence of ST segment elevation, but suspicion remained high for thoracic or abdominal aortic catastrophe. Bedside ultrasound demonstrated no pericardial effusion, a severely hypokinetic myocardium and a question of fluid in the left perinephric space. Attempts were made to resuscitate the patient, and an ED chest/abdomen/pelvis CT showed a type A acute thoracic aortic dissection. Unfortunately, the patient remained profoundly unstable, with multiple arrests. He was transferred to a tertiary care facility, but expired shortly after arrival. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: An emergency physician needs to be aware of the myriad of presentations of acute aortic dissection. Although hematospermia was felt ultimately to be an incidental symptom, sexual activity may bring about a significant transient increase in blood pressure, which could contribute to sheer force causing aortic injury. Awareness of this trigger and a careful sensitive history may aid the clinician in early diagnosis.
