Randomized Controlled Trial
End-Tidal Oxygen Saturation with Nasal Cannula During Noninvasive Positive Pressure Ventilation: A Randomized Crossover Trial.
Simultaneous use of nasal cannula (NC) with noninvasive positive pressure ventilation (NIPPV) may help streamline the transition from preoxygenation to intubation with apneic oxygenation in patients with deteriorating respiratory status, but may also compromise preoxygenation by impairing NIPPV mask seal. ⋯ The mean difference confidence interval did not include the noninferiority margin. Hence, NIPPV with NC seems noninferior to NIPPV alone with regard to EtO2. These results indicate that concomitant use of NC with NIPPV may be an appropriate preoxygenation strategy in anticipation of the potential need for transition to intubation.

Pulmonary embolism (PE) is a disease diagnosed relatively frequently in emergency departments (EDs). Evidence suggests that improved decision making may decrease inappropriate testing, unnecessary radiation exposure, and non-beneficial treatment. Several studies have looked at the utility and safety of age-adjusting the D-dimer levels used to safely rule out PE. ⋯ Age-adjusted D-dimer cutoff values, in combination with a non-high clinical probability, is safe and effective to essentially rule out PE in ED patients.

Ghana is a developing country that has strategically invested in expanding emergency care services as a means of improving national health outcomes. ⋯ Emergency medicine as a horizontal component of low- to middle-income countries' health systems may fuel national health and economic development. Ghana's experience may serve as a model.

Humerus fractures caused by the throwing motion are extremely rare. They have been reported mostly in recreational adult athletes in their third or later decades of life. A pediatric thrower's fracture is even less common, with few reported cases. The pediatric version of this fracture is located in the proximal to midshaft humerus, distinguishing it from the adult type, which occurs in the middle to distal shaft. ⋯ A 12-year-old male pitcher experienced a "snap" in his right arm while throwing a pitch in a baseball game. He presented to the Emergency Department with right arm pain and deformity. He was misdiagnosed with a right glenohumeral dislocation and a reduction maneuver was attempted prior to any radiographic imaging. Upon further review of the imaging and outpatient follow-up, he was found to have a humeral spiral fracture consistent with a "ball-thrower's fracture." The fracture healed with conservative treatment and he returned to unrestricted sports participation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Recognition of this fracture is important to avoid unnecessary and potentially harmful treatment of the pediatric patient. A thrower's fracture of the pediatric humerus is rare, but glenohumeral dislocation without direct trauma is even less common and has never been reported as a result of the throwing motion in a pediatric patient. Radiographic imaging is important, and consideration of the thrower's fracture should be in the differential for any patient presenting with acute pain and deformity of the arm resulting from throwing any object.

Observational Study
Effectiveness of Outpatient Antibiotics After Surgical Drainage of Abscesses in Reducing Treatment Failure.
The optimal approach to outpatient antibiotic use after surgical drainage of abscesses is unclear given conflicting clinical trial results. ⋯ This real-world, comparative effectiveness analysis did not demonstrate any significant reduction in treatment failure with the use of antibiotics after drainage of abscesses in the ED. It is unclear if the clinical benefit observed under controlled trial conditions will carry over to routine clinical practice where varied antibiotic regimens are the norm and local bacterial resistance patterns vary.
