September’s Current Opinion in Pulmonary Medicine has 4-5 review articles each on sarcoidosis (how to handle calcium problems; cardiac sarcoid); interstitial lung disease (biologics for connective-tissue disease related ILD; LAM therapies; stem cell therapy for pulmonary fibrosis), and pulmonary vascular disease. Curr Opin Pulm Med 2011;17.

Do we need to worry about pre-existing heparin-induced thrombocytopenia antibodies in people admitted with pulmonary embolism / deep venous thrombosis? Or can we keep happily slinging heparin at first sight? Warkentin et al analyze data from the Matisse VTE studies, which enrolled 3,994 patients with DVT or PE. All had ELISA HIT antibodies collected at [… read more]

Aujesky et al randomized 344 people in 19 European emergency departments with low-risk pulmonary embolism to either be sent home with enoxaparin and warfarin within one day, or to be treated until therapeutic on warfarin in-hospital. They were then treated for 90 days. One of 171 home-treated patients developed recurrent VTE, while none of the [… read more]

Douma et al compared the Wells score, Geneva score, and the simplified versions of each, combined with D-dimer, on a prospective cohort of 807 patients with suspected PE (~23% of whom were found to have PE). With a negative D-dimer and a low-probability score using any rule, risk of pulmonary embolism was ~0.5%. However, only [… read more]

Salaun et al publish their experience using a simple algorithm for management of 321 consecutive patients with suspected pulmonary embolism at one center in France. The tool sought to avoid CT-angiography (and associated radiation) wherever possible, instead favoring leg ultrasounds and ventilation-perfusion scans. Only the indeterminate cases (a mere 35, or 11%) underwent CT-A. In [… read more]

Drospirenone is the new progesterone analog in heavily marketed new oral contraceptive pills (trade names Yaz, Yasmin, Angelique). Using a large insurance claims database, Jick et al identified 186 cases of DVT or PE in women aged 15-44 taking oral contraceptives and compared them to controls. Those taking drospirenone-containing OCPs had a nonfatal DVT/PE incidence [… read more]

ICU patients have a 5-10% risk of deep venous thrombosis, even with appropriate prophylaxis. Ultrasound screening can detect many of these asymptomatic and clinically unsuspected DVTs. However, since many DVTs disappear without incident, and complications can result from additional testing and treatment with anticoagulation, and all of this costs money, the best approach to prevention [… read more]
