CT venography vs ultrasound in the diagnosis of thromboembolic disease in patients with clinical suspicion of pulmonary embolism.

To assess the reliability of indirect computed tomography venography (CTV) in the detection of deep venous thrombosis (DVT) in patients with clinical suspicion of pulmonary embolism (PE). 235 consecutive patients with suspicion of PE underwent an imaging protocol composed of a CT pulmonary angiography (CTPA), a CTV and an ultrasound study of the deep venous system, which was considered the "gold standard." Sensitivity, specificity, and predictive values were calculated for CTV.

Necrotizing fasciitis secondary to diverticulitis.

Necrotizing fasciitis is a rare, rapidly progressive infectious process primarily involving the fascia and the subcutaneous tissue, with thrombosis of the cutaneous microcirculation. We present a case of necrotizing fasciitis secondary to diverticulitis in an immunosuppressed patient with rheumatoid arthritis.
