Cavitary lesions on a chest radiograph can be the manifestations of various diseases. The etiologies include abscess, mycobacterial infections, fungal infections, parasite infection, cavitary tumors, septic pulmonary embolism and vasculitis. While in comparison with the causes that could simultaneously develop a complete heart block, the differential diagnosis is limited. ⋯ Cardiac involvements are not rare in Wegener's granulomatosis, but are not usually clinically apparent. A complete atrioventricular block is a rare but treatable manifestation of cardiac involvement usually indicating early active systemic disease. Patients presenting with cardiac abnormalities and evidence of systemic inflammation should be screened for Wegener's by history, radiographic and laboratory assessment.

Point-of-care ocular ultrasonography is emerging as a powerful tool to evaluate emergency department (ED) patients at risk for ophthalmologic and intracranial pathology. We present cases of 3 patients in whom optic disc swelling was identified using ocular ultrasound. Causes for optic disc swelling in our patients included idiopathic intracranial hypertension, secondary syphilis, and malignant hypertension with associated hypertensive retinopathy. Because direct visualization of the optic disc may be challenging in an ED setting, ultrasound examination of the optic disc may represent an important adjunct to fundoscopy when assessing patients with headache or visual complaints.

Most commonly, patients with pulmonary embolism present with dyspnea, chest pain, and/or tachypnea to the emergency department (ED). The presence of multiple suggestive symptoms, especially when severe, significantly reduces delay in diagnosis. ⋯ The combination of absence of specific symptoms regarding pulmonary embolism and radiologic findings of an obstructed pulmonary artery supplying the cavitary lung segment is rare. Common etiologies of cavitary lung processes are discussed, and risk factors of pulmonary infarction are highlighted.

Treatment of pain in the emergency department (ED) is a significant area of focus, as previous studies have noted generally inadequate treatment of pain in ED patients. Previous studies have not evaluated the impact of computerized physician order entry (CPOE) on the treatment of pain in the ED. We sought to evaluate treatment of pain before and after implementation of CPOE in an academic ED. ⋯ The use of CPOE in the ED may offer modest benefits in the treatment of patients with pain-related complaints.

The objective of this study was to assess the impact of an emergency department (ED)-only full-capacity protocol and diversion, controlling for patient volumes and other potential confounding factors. ⋯ Our predivert/full-capacity protocol is a simple and generalizable strategy that can be implemented within the boundaries of the ED and is significantly associated with a decreased diversion rate.
