RESUMO

The risk perceptions and self-protective behavior of 282 immigrant farm workers (all of Mexican origin) in response to pesticide exposure were examined. Several variables were predicted to influence reactions, but some deviations from past studies were expected because cultural or socioeconomic factors could modify risk responses. In keeping with predictions, greater risk perceptions were associated with beliefs that past harm had occurred, future harm to self or offspring was likely, precautions were less effective, and cancer-causing agents were mostly unavoidable. Self-protective behavior was most likely for those receiving risk information, having greater perceptions of control over health and the occupational situation, and believing that precautionary methods were effective. The discussion considers variability in responses to chronic risk and the broader perspective offered by environmental hazard studies.

RESUMO

We evaluated the fluorescein-conjugated monoclonal antibody (FA) test for screening for Chlamydia trachomatis endocervical infection in a general adolescent clinic. Three hundred sixty-three consecutive adolescent girls, ages 13 to 20 years (mean 17.3 years) were examined. Forty-five (12%) FA smears had insufficient cells. Reason for visit included non-lower genital tract-related disorders in 241 (76%) girls, and lower genital tract-related disorders in 77 (24%). C. trachomatis was isolated by tissue culture in 46 (14%) patients, and Neisseria gonorrhoeae by culture in 22 (7%), and Trichomonas vaginalis was identified by wet mount in 13 (5%). Compared with our tissue culture technique, the performance of the FA test was as follows: sensitivity 61% (28 of 46), specificity 97% (264 of 272), positive predictive value 78% (28 of 36), and negative predictive value 94% (264 of 282). There was no significant difference in test performance by race, although the sensitivity rate (64%) of the test in blacks was twice that (30%) in nonblacks. This apparent difference in test performance by race may actually represent variations in group characteristics, including exposure rate, susceptibility, and number of inclusion forming units available for tissue culture of Chlamydia in blacks compared with nonblacks. In our adolescent clinic, the tissue culture is superior to FA in detecting Chlamydia. We recommend that the FA test be used where tissue culture isolation for Chlamydia is not readily available, where known or predicted chlamydial infection rates are high, and where known or predicted numbers of inclusion forming units of Chlamydia in tissue culture are high.

RESUMO

The first five years' experience of a small, Caribbean, hospital-based haemodialysis unit is reviewed with particular reference to the aetiology of end-stage renal failure (ESRF), complications of therapy, causes of death and the factors influencing rehabilitation. Malignant hypertension evolved as an important cause of ESRF, accounting for 42 percent of cases among Black Barbadians on the dialysis programme (AU)
