The authors cultured 2,320 patients who attended the Denver Metro Health Clinic for Sexually Transmitted Diseases from September 1981 to June 1983 to determine clinical and epidemiologic factors associated with genital chlamydial infection. Among consecutive heterosexual men with urethral discharge, 226 of 849 (27%) had positive urethral cultures, with rates significantly lower among those with profuse (18%) or purulent (19%) discharges, and higher (37%) among those with symptoms for more than seven days. In a subgroup of men without gonococci, those who had polymorphonuclear leukocytes on smear had higher isolation rates (33%) than those who did not (3%). ⋯ Younger age was significantly associated with chlamydial isolation in both men and women after controlling for sexual activity and other factors. Various patient characteristics can be combined to define subgroups of men and women, with rates of isolation ranging from under 4% to over 60%. These results can be useful in deciding whom to test and whom to treat presumptively in a public health setting.

Vaginal bleeding patterns among women using one natural and eight hormonal methods of contraception.
Menstrual diary records were obtained from a total of 5257 women using nine different methods of contraception, one natural and eight hormonal. This paper presents a comparative analysis of their vaginal bleeding patterns. The analytic procedures follow the recommendations of a recent WHO workshop on bleeding pattern analysis, which involve dividing each subject's diary into successive 90-day reference periods, calculating ten indices for each period, and classifying women according to whether they have "clinically important" bleeding disturbances. ⋯ The incidence of amenorrhea rose from just under 10% in their first injection interval to over 40% in their fourth. The methods of analysis recommended by WHO in 1985 still require substantial refinement. Nevertheless, they are more sensitive than those used previously for WHO trials and produce an easily understood, clinically meaningful characterization of bleeding patterns.

A microcomputer software was developed to analyse menstrual diaries following the reference period method as described in the article "The analysis of vaginal bleeding patterns induced by fertility regulating methods" published in this journal (Contraception, 34:253-260, 1986). The programme allows the analysis of groups of diaries selected according to subjects' characteristics recorded at commencement of the diary. ⋯ The output can be presented graphically as Box-whisker plots. A tutorial is included in the package.

ReviewAIDS education in the schools: a literature review as a guide for curriculum planning.
As plans for massive public AIDS education grow, pediatricians will become increasingly involved with school systems as consultants and leaders. A review of relevant literature on students' current level of knowledge about AIDS and on educational efforts to date with high-risk groups (homosexuals and intravenous drug users) provides the rationale for school-based AIDS education. Literature describing the approaches used and the impact of programs for sex education, drug abuse prevention, and reduction of prejudice towards the disabled is reviewed to extrapolate that which applies to AIDS education. Important developmental characteristics of adolescents are discussed insofar as they have implications for the planning of AIDS curricula.

Risk of breast cancer in relation to reproductive factors in Denmark.
The effect of reproductive factors on breast cancer risk was evaluated in a population-based case-control study, including 1,486 breast cancer cases diagnosed over a one-year period in Denmark. They were identified from the files of the nationwide trial of the Danish Breast Cancer Co-operative group and the Danish Cancer Registry. The control group was an age-stratified random sample of 1,336 women from the general population. ⋯ Trends of decreasing risk were observed by increasing parity and age at menarche. These findings were independent of age at first full-term pregnancy which overall was not related to breast cancer risk, though a weak association appeared in women less than 50 years at diagnosis. The study confirmed that pregnancies must continue to term to offer protection against breast cancer.
