The European Society of Cardiology just weighed in on the 3 new alternatives to warfarin for oral anticoagulation. The response is tempered enthusiasm.

Phrenic nerve paralysis can present with chest wall pain, cough, and exertional dyspnea mimicking cardiac dyspnea. Fluoroscopy is the most reliable way to document diaphragmatic paralysis, and the sniff test confirms that abnormal hemidiaphragm excursion is due to paralysis rather than unilateral weakness.

A 58-year-old man with a past medical history of chronic sinus disease and hypothyroidism presented with left periorbital pain and erythema that worsened despite outpatient treatment with topical antibiotics. An outpatient CT scan showed pansinusitis and orbital stranding. The diagnosis was orbital cellulitis and sinusitis.
