Right bundle branch block (RBBB) is occasionally encountered in young persons who lack any other evidence of overt cardiac disease (Hiss and Lamb, 1962; Lancaster, Schechter, and Massing, 1972). The block may be complete or incomplete, the latter being more common. Right bundle branch block has been studied in relation to body weight, obesity, serum cholesterol and glucose levels, and blood pressure, but the results have been negative (Ostrander, 1964; Kannel et al., 1962). Data presented here suggest that incomplete RBBB is related to vital capacity. [ABSTRACT FROM PUBLISHER]

Fifty-one women with lung cancer and 163 other hospital patients were interviewed regarding the smoking habits of themselves and their husbands. Forty of the lung cancer cases and 149 of the other patients were non-smokers. Among the non-smoking women there was a statistically significant difference between the cancer cases and the other patients with respect to their husbands' smoking habits. Estimates of the relative risk of lung cancer associated with having a husband who smokes were 2.4 for a smoker of less than one pack and 3.4 for women whose husbands smoked more than one pack of cigarettes per day. The limitations of the data are examined; it is evident that further investigation of this issue is warranted.

Smoking histories were obtained from 79 patients with primary hepatocellular carcinoma (PHC) (of whom 40 were negative and 39 positive for serum hepatitis B surface antigen), 39 patients with liver cancer not primary in the liver (LCNP), and 204 hospitalized controls. All subjects were Caucasians of Greek nationality and residence. No significant difference in smoking habits was found between controls and either PHC patients positive for serum hepatitis B surface antigen or LCNP patients. In contrast, there was a highly significant association between smoking and PHC negative for serum hepatitis B surface antigen (P less than 10(-4)); this association was not accounted for by the greater alcohol consumption of smokers. The risk ratios were 1.3, 2.5, 3.7, and 8.4 for current smokers of 1-10, 11-20, 21-30, and 30+ cigarettes per day.
