Social Media Use by American Association of Hip and Knee Surgeons Members.

Introduction: Social media offers physicians marketing opportunities previously unavailable. We sought to evaluate social media use and its correlation with public rankings among Association of Hip and Knee Surgeons members.

Methods: A list of members and demographics was collected.

An Enigmatic Case of Skeletal Fluorosis: Inhalant-Induced Toxicity.

Skeletal fluorosis is more common in the developing world, but is occasionally seen in the United States. We present radiographic, scintigraphic, CT, and clinical images of a 26-year-old woman with rapidly progressive, debilitating, polyostotic periostitis, and diffuse osteosclerosis typical of skeletal fluorosis. Laboratory analyses supported this diagnosis.

AAOS Clinical Practice Guideline Summary: Prevention of Surgical Site Infection After Major Extremity Trauma.

Prevention of Surgical Site Infections After Major Extremity Trauma Evidence-Based Clinical Practice Guideline is based on a systematic review of current scientific and clinical research. This clinical practice guideline (CPG) is designed to assist qualified physicians and clinicians when making treatment decisions for adults (18 years or older) who have sustained major extremity trauma. The CPG workgroup defined major extremity trauma as an open fracture, a major/high-energy closed fracture, a degloving injury, Morel-Lavallée lesions, a low-energy or high-energy gunshot injury, a crush injury, a blast injury, or any other moderate-energy to high-energy injury.

Gastric Emphysema: A Cannot-Miss Emergency Medicine Diagnosis.

The radiographic finding of gastric emphysema with portal venous gas is classically an ominous finding, associated with a high rate of mortality. Although classically the case, this imaging finding must be quickly correlated with the overall clinical picture, allowing for the essential differentiation between the highly lethal emphysematous gastritis and the much more benign gastric emphysema, each of which has drastically different management strategies. We report a case of gastric emphysema with portal venous gas likely attributable to a gastric outlet obstruction and gastric mucosal defect in a 17-year-old girl with a chief complaint of syncope that was diagnosed in the emergency department and treated conservatively.

Atrial fibrillation in pregnancy.

Background: Physiologic changes of pregnancy can predispose women to cardiac arrhythmias. Atrial fibrillation is rare in pregnancy and usually occurs in women with underlying cardiac anomalies.

Case: A young woman at 22 weeks of gestation presented with new-onset atrial fibrillation with rapid ventricular response.
