A survey of anesthetic health hazards among dentists.

Measurable concentrations of waste anesthetic gases have been found in hospital dental operating rooms. A mail survey of 4,797 general dental practitioners and 2,642 oral surgeons indicated that 20.2% of the general practitioners and 74.8% of the oral surgeons had anesthetic exposures exceeding three hours per week. In the comparison of the health of individuals exposed or unexposed to inhalation anesthetics, there was a significant increase (78%) of spontaneous abortion in the spouses of exposed dentists and a significant increase (156%) in liver disease for exposed dentists. The implication of these findings and possible solutions are discussed.

Breast cancer: a critical review of a patient sample with a ten-year follow-up.

Records of 407 patients with primary breast cancer treated at the M.D. Anderson Hospital in 1958 and 1959 were reviewed with regard to patient characteristics, treatment, and results. These patients presented with relatively advanced disease (42% were inoperable on initial evaluation). Black and Chicano patients had significantly more advanced disease on admission than did white patients. Approximately 61% of patients received treatment appropriate to their clinical category indicating that multiple factors influence therapy selection. Absolute ten-year survival free of disease was 21%. Black and Chicano patients with early disease (categories 1 and 2) had significantly worse survival than did white patients. Problems with retrospective studies are multiple and limit the validity of conclusions. Randomized controlled studies are essential to answer critical questions.
