Smoking is the leading controllable risk factor for heart disease. Only about 69% of U.S. indoor workers are currently covered by a smoke-free workplace policy. This analysis projects the cardiovascular health and economic effects of making all U.S. workplaces smoke free after 1 year and at steady state. ⋯ Making all U.S. workplaces smoke free would result in considerable health and economic benefits within 1 year. Reductions in passive smoking would account for a majority of these savings. Similar effects would occur with enactment of state or local smoke-free policies.

PRESENTING FEATURES: An 18-year-old white man was admitted to the Osler Medical Service with the chief complaint of back pain. Two weeks prior to admission, the patient developed diffuse and aching upper back pain. Over the next couple of days, he also developed severe anterior chest pain that was somewhat pleuritic in nature but diffuse and extending bilaterally into the shoulders. ⋯ A white blood cell differential revealed 7% bands, 53% polys, 34% lymphs, 5% atypical lymphocytes, 2% nucleated red cells, and a few young unidentified cells. His chemistry studies were unremarkable. What is the diagnosis?

To determine the incidence of deep vein thrombosis and pulmonary embolism in two cohorts representing regions of the United States. ⋯ The incidence of venous thromboembolism in this cohort of middle- and older-aged subjects was similar to that observed in more geographically homogeneous samples. Half of cases were idiopathic. Short-term mortality and 2-year recurrence rates were appreciable, especially among subjects with cancer. Based on this study we estimate that 187,000 cases of first-time venous thromboembolism are diagnosed yearly in the United States among those aged 45 years or older.
