Ionizing radiation and cost make ultrasound (US), when available, the first imaging study for the diagnosis of suspected pediatric appendicitis. US is less sensitive and specific than computed tomography (CT) or magnetic resonance imaging (MRI) scans, which are often performed after nondiagnostic US. ⋯ Overweight and older patients are more likely to have a nondiagnostic US or appendicitis, and it may be more efficient to consider alternatives to US first for these patients. Also, this information about the accuracy of US to diagnose suspected appendicitis may be useful to clinicians who wish to engage in shared decision-making with the parents or guardians of children regarding imaging options for children with acute abdominal pain.

Topical cocaine is sometimes used for the treatment of epistaxis, as it has both potent anesthetic and vasoconstrictive properties. Cocaine has unpredictable cardiovascular effects, such as sudden hypertension, tachycardia, coronary arterial vasoconstriction, and dysrhythmia. ⋯ We report a case of acute iatrogenic cardiovascular toxicity from the use of topical cocaine in a 56-year-old man presenting to the Emergency Department with profound epistaxis. To prepare for cauterization and nasal packing, the patient received 4% topical cocaine-soaked nasal pledgets. He became hypertensive, tachypneic, tachycardic, and dysphoric immediately after administration. To directly counter these adverse hyperadrenergic effects, the patient was given 10 mg intravenous labetalol, a mixed β- and α-blocker. This instantly normalized his vital signs and adverse subjective effects. His epistaxis was successfully treated, and he was discharged 1 h later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We believe that emergency physicians should be aware of the unpredictable acute cardiovascular toxicity of topical cocaine. Labetalol represents an effective first-line treatment, which, unlike benzodiazepines, directly counters the pharmacologic effects of cocaine and has no respiratory or sedative side effects. Labetalol, with its mixed β/α-blocking properties, also mitigates the potential for "unopposed α-stimulation."

Scribe use throughout health care is becoming more common. There is limited peer-reviewed literature supporting this emerging role in health care despite rapid uptake of the role. ⋯ Scribes had a positive impact on RVUs in adult but not pediatric patients. Among adults, scribes led to higher RVUs in ESI 2 and 3 but not 4 and 5 patients, perhaps suggesting a limitation to improve revenue capture on lower-acuity patients.

Transient ischemic attack (TIA) affects over 200,000 patients annually in the United States, and it precedes approximately 14% to 23% of strokes. Patients are typically admitted for evaluation and management. ⋯ TIA is a condition with high risk for stroke. Imaging is often not reliable, nor is the use of risk scores alone. The American College of Emergency Physicians provides a Level B Recommendation for the use of rapid diagnostic protocols to determine patient short-term risk for stroke while avoiding the reliance on stratification instruments to discharge patients from the ED.
