Four new cases of carotid body tumors are reported, all familial, including 2 patients with bilateral tumors. The embryology, physiology, pathology, natural history, and treatment of these rare tumors are reviewed. It is recommended that all carotid body tumors be excised unless there are contraindicating medical or technical reasons.
Admission blood alcohol levels (BAL) were obtained in 111 adult passenger/driver pairs injured in vehicular crashes. Drinking patterns were studied, including the influence of the sex of the occupants on alcohol consumption. Alcohol was not a factor in 44 of the crashes. In 48 of 62 crashes (77%), the driver was either the sole drinker or had a higher BAL than the passenger. In five crashes, the passenger was the only drinker. Female drivers were drinking 40% of the time, compared to 60% of male drivers. Overall, 77.4% of the drinking drivers had a BAL of 100 mg/100 ml. When vehicular occupants were of the same sex, as opposed to both sexes, the drivers drank more frequently (62.9% vs. 43.9%). In 13 of 14 cases of a drinking male driver transporting a female passenger, the female passenger had not been drinking or had done so to a lesser degree. The data indicate that educational efforts should be directed at discouraging passengers from riding with drinking drivers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
