Bone mineral content in smokers.
We did a cross-sectional evaluation of the effect of heavy cigarette smoking on bone mass using single photon absorptiometry (SPA) of the radius in 35 smokers (24 women, 11 men) and 35 nonsmokers (24 women, 11 men). Individuals from the two groups were carefully matched for sex, age, weight, height, calcium intake, and, for women, menopausal history and estrogen use. We found no differences between smokers and nonsmokers at the middle or distal portion of the radius. This suggests that smoking has no direct effect on appendicular bone mass; however, it may still influence bone loss indirectly through effects on other factors such as age at menopause, body weight, diet, and possibly physical activity.

Incidence of fever and bacteremia following transbronchial needle aspiration.
Fiberoptic bronchoscopy and transbronchial needle aspiration were performed on 50 occasions in 47 afebrile patients. The aspirations were followed by endobronchial or transbronchial biopsies in 22 patients, as well as bronchial brushings and washings where appropriate. Blood for cultures was drawn at 5 and 30 minutes following needle aspiration, as well as at the time of any temperature above 38 degrees C during the 24 hours following the procedure. In five (10 percent) of the 50 cases, there was temperature greater than 38 degrees C (100.4 degrees F) in the 24 hours following the bronchoscopy; in no patient were cultures of blood positive, whether done early after the procedure or at the time of fever. We conclude that transbronchial needle aspiration, a new procedure gaining widespread popularity in diagnostic thoracic medicine, is not associated with clinically detectable bacteremia. This procedure should not require antimicrobial prophylaxis in patients susceptible to endocarditis.
