Rapid atrial fibrillation (AF) is commonly associated with ST-segment depressions. ST-segment depression during a chest pain episode or exercise stress testing in sinus rhythm is predictive of obstructive coronary artery disease (CAD), but it is unclear if the presence or magnitude of ST-segment depression during rapid AF has similar predictive accuracy. ⋯ ST-segment depression during rapid AF is not predictive for the presence of obstructive CAD.

A 42-year-old man noted decreased urine output and visited our emergency department. He said that 3 days previously, he had gotten drunk and fallen down a set of stairs. Blood tests and abdominal contrast-enhanced computed tomography revealed no abnormalities. ⋯ Microscopic examination of his ascitic fluid sediment revealed the presence of hyaline casts enclosing renal tubular epithelial cells. Cystography demonstrated contrast medium leakage into the peritoneal cavity, which led to a diagnosis of bladder rupture. Examination of ascitic fluid sediment is simple and very useful for diagnosing bladder rupture.

Adults older than 50 years are at greater risk for death and severe disability from influenza. Persons in this age group, however, are frequently not vaccinated, despite extensive efforts by physicians to provide this preventive measure in primary care settings. We performed this study to determine if influenza vaccination of older adults in the emergency department (ED) may be cost-effective. ⋯ Vaccination of older adults against influenza in the ED setting is cost-effective, especially for those older than 65 years. Emergency departments may be an important setting for providing influenza vaccination to adults who may otherwise have remained unvaccinated.

Obesity is a growing problem in the United States. Obesity alters the pharmacokinetic profiles of various drugs. Although there are guidelines for dose adjustments for many of the antibiotics commonly used in the emergency department (ED), they are seldom used. ⋯ Emergency physicians frequently underdose cefepime, cefazolin, and ciprofloxacin in obese patients. Underdosing antimicrobials presents risk of treatment failure and may promote antimicrobial resistance. Education is necessary to improve early antibiotic administration to obese patients.
