BOSTON -- The gender gap in multiple sclerosis has doubled over the past six decades, reaching about four women with the disease for every affected man, investigators reported here.

ANN ARBOR, Mich. -- Several genetic regions appear to contribute to the risk of developing type 2 diabetes, three research groups have found in a major collaborative effort.

DURHAM, N.C. -- Strains, sprains, and pains are more common in obese employees than in normal-weight workers, costing U.S. companies billions of dollars, researchers here reported.

OXFORD, England -- Use of hormone replacement therapy for at least five years added up to 1,300 additional ovarian cancers over 14 years in Britain and 1,000 extra deaths, researchers here reported.

For several months, a 52-year-old woman has had burning discomfort in the region of her lower sternum and frequent acid/sour sensations in her throat; the symptoms are usually associated with burping after meals and recumbency.

EXETER, England -- The first clear genetic link to obesity for the common man or woman may have been discovered by researchers here.

BETHESDA, Md. -- Women who began hormone replacement therapy within 10 years of starting menopause appear to be at a lower risk for coronary heart disease than women who start after a decade.

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.
