abstract: Low molecular weight heparins (LMWHs) have proved to be as safe and effective as unfractionated heparin for the treatment of venous thromboembolism. They have the advantage of not requiring frequent measurement of activated partial thromboplastin time and subsequent dosage adjustments. Patients who have deep venous thrombosis can be treated with once- or twice-daily subcutaneous doses. Hospital admission is necessary for patients with risk factors for major bleeding complications, for those with symptomatic pulmonary embolism, or when noncompliance is likely. Symptomatic proximal deep venous thrombosis and asymptomatic pulmonary embolism may be managed on an outpatient basis if there are no contraindications. Although heparin-induced thrombocytopenia occurs less frequently with LMWHs than with unfractionated heparin, the platelet count must still be monitored during therapy.

abstract: Hemoptysis has many causes, including bronchiectasis, lung cancer, and bronchitis. The initial goals of the history and physical examination are to differentiate hemoptysis from epistaxis and hematemesis and then to establish its severity. A variety of signs and symptoms may suggest the underlying cause. For example, hematuria suggests vasculitis or an immunologically mediated disease, such as Wegener granulomatosis or systemic lupus erythematosus. The workup includes chest radiography and measurement of hemoglobin and hematocrit levels, platelet count, international normalized ratio, activated partial thromboplastin time, and creatinine level. Chest CT scanning often identifies sources of bleeding that are not apparent on radiographs and sometimes can be used in conjunction with bronchoscopy. Patients with massive hemoptysis should be hospitalized for rapid evaluation and intervention; treatment may include interventional bronchoscopy, angiography, or embolization.

Oral Contraceptives: Five Vignettes Illustrate Dx and Rx Problems-- and Solutions

A 57-year-old woman presents with swelling of the hands that began several weeks earlier and is now worsening. She denies joint pain, and she has no history of trauma or significant vascular disease. She has had pneumonia several times; each episode was successfully treated with antibiotics. She has smoked 2 packs of cigarettes a day for the past 20 years

Binge eating disorder is more common than anorexia and bulimia combined, according to a national survey, but many physicians are unaware of the problem. The guidance and evidence discussed here highlight the key issues in recognizing and managing the disorder.

DURHAM, N.C. -- Biopsies may underestimate the severity of prostate cancer in obese men, a team of investigators found.
