THE USE OF LIFE TABLES IN PUBLIC HEALTH WORK

In this paper a man not professionally engaged in public health work but familiar with the difficulties of rendering vital statistics useful in that work and technically trained to cope with such difficulties, discusses some of the important features of "The Book-keeping of Public Health."     

Relationships between histology, monoclonal antibody reactivity, and prognosis in breast cancer

Infiltrating ductal carcinoma of the breast is histologically heterogeneous and may be subdivided into three main types (A, B, and C) which correlate with the likelihood of long-term survival. Examples of each type were tested against three monoclonal antibodies (H59, H71, and H72) prepared against the breast cancer cell line ZR-75-1. The reaction patterns of type B tumors were significantly different from those of types A and C with antibodies H59 and H71, but not with H72. Thus, the reactivity to these monoclonal antibodies, and presumably the antigen composition of the tumor cells, correlates with the histologic appearances and probability of long-term survival.     

Cardiac teratogenicity of dichloroethylene in a chick model.

Trichloroethylene (TCE) and dichloroethylene (DCE) are related halogenated aliphatic hydrocarbon industrial solvents that are frequently found as drinking water contaminants. TCE has been implicated as a cardiac teratogen in an epidemiologic study and in a chick model. The purpose of this study was to determine whether DCE was also a cardiac teratogen in the chick embryo. Fertilized White Leghorn chick eggs (n = 418) were inoculated just above the embryo with 30 microL of a test solution on d 3 of incubation. Two control groups were studied: normal saline (n = 96) and the diluent for the DCE, mineral oil (n = 108). DCE was studied at three doses: 5, 20, and 25 microM (n = 76, 62, and 76, respectively). Eggs were coded with a seven-digit number to mask identity. Chicks were terminated on d 18 of incubation, and, after external inspection, hearts and great vessels were dissected macroscopically according to a detailed protocol. Abnormal hearts were reviewed and the diagnosis was agreed upon by three investigators before decoding the seven-digit number and photographing the abnormality. Some embryo death and subsequent tissue autolysis occurred in all groups, but, compared to controls, it was not significantly greater in the treatment group. However, combining all controls and all experimentals, significantly more (p = 0.02) embryonic death occurred in the experimental group. Noncardiac anomalies occurred in 17 embryos and were highest in the saline (four), 5 microM (four), and 20 microM (seven) DCE groups.(ABSTRACT TRUNCATED AT 250 WORDS)     

HIV antibody testing among adults in the United States: data from 1988 NHIS.

Data collected from 21,168 adults using the 1988 AIDS supplement to the National Health Interview Survey were examined to determine awareness of and experience with HIV antibody testing in the United States. Three-fourths of adults knew of the blood test for HIV antibodies; awareness was lower among Blacks, Hispanics, older adults, and those less educated. Overall, 17 percent of adults had been tested; of these, 73 percent because of blood donation, 14 percent through other non-voluntary programs (such as military induction), and 16 percent sought testing voluntarily. While a smaller proportion of Black and Hispanic adults had been tested, they were more likely than their White non-Hispanic counterparts to have been tested voluntarily. Persons who reported belonging to groups with high-risk behaviors were also more likely to have been voluntarily tested. Most of those tested voluntarily received their test results, but only one-third also received prevention information. Three percent of adults plan to be tested voluntarily in the next year; about half will seek testing through their doctor or health maintenance organization.
