Discussing STIs: doctors are from Mars, patients from Venus.

BACKGROUND: Primary care plays an important role in promoting sexual health, but in this setting counselling regarding sexually transmitted infections (STIs) is rarely performed and often inadequate. OBJECTIVE: Our aim was to identify and quantify the barriers physicians encounter in discussing STIs with their patients. METHODS: A postal questionnaire-based survey was carried out in a random sample of 200 primary care physicians in Antwerp, Belgium. RESULTS: The response rate was 68%. Among the 122 respondents, only 44.3% provide some form of counselling (asking about sexual history, informing about safe sex or informing about STIs) regularly, at least once a week. Major barriers are language and comprehension problems (for 74.2% of respondents), ethnic differences (68.4%), insufficient training (69.4%), lack of time (60.8%), presence of the patient's partner (89.2%) or mother (94.2%), first contact with a patient (60.8%), fear of embarrassing the patient (30.6%) and a patient without genital complaints (71.4%). About half of the GPs fail to counsel an asymptomatic patient with obvious STI risk, and as many give no safe sex advice in a first contraception consultation. CONCLUSIONS: Physicians have many and various barriers to discussing STIs with their patients. Features of contemporary STI counselling and solutions to its problems are discussed. Education of health care providers should be given priority.

First Person Account: landing a Mars lander.

The article that follows is part of the Schizophrenia Bulletin's ongoing First Person Account series. We hope that mental health professionals--the Bulletin's primary audience--will take this opportunity to learn about the issues and difficulties confronted by consumers of mental health care. In addition, we hope that these accounts will give patients and families a better sense of not being alone in confronting the problems that can be anticipated by persons with serious emotional difficulties. We welcome other contributions from patients, ex-patients, or family members. Our major editorial requirement is that such contributions be clearly written and organized, and that a novel or unique aspect of schizophrenia be described, with special emphasis on points that will be important for professionals. Clinicians who see articulate patients with experiences they believe should be shared might encourage these patients to submit their articles to Schizophrenia Bulletin, First Person Accounts, EEI Communications, 66 Canal Center Plaza, Suite 200, Alexandria, VA 22314.--The Editors.

Bayesian survival analysis using a MARS model.

A Bayesian multivariate adaptive regression spline fitting approach is used to model univariate and multivariate survival data with censoring. The possible models contain the proportional hazards model as a subclass and automatically detect departures from this. A reversible jump Markov chain Monte Carlo algorithm is described to obtain the estimate of the hazard function as well as the survival curve.

Serological reactions of leptospirosis-positive (MAR and CFT) bovine sera in ELISA.

The collection of test sera for measuring ELISA results was composed of bovine sera with MAT titres of greater than or equal to 1:200 in the leptospirosis MAT and of greater than or equal to 1:5 in the CFT together with sera from a serologically negative and clinically non-suspicious cattle herd. To establish cut-off ODs, the geometric mean net-extinction of the negative serum collection plus 1, 2, and 3 standard deviations were calculated. By comparison of 3 different conjugates from rabbits, it was demonstrated that results from anti-total bovine Ig were superior to anti-IgG and anti-IgM conjugates. Considerations regarding sensitivity and specificity led to the recommendation to use a test serum dilution of 1:160, to apply anti-total bovine Ig conjugates, and to establish the cut-off OD at the geometric mean net-extinction of negative sera plus 3 standard deviations. Under such conditions, agreement between leptospirosis MAT/CFT positivity on the one side and ELISA positivity on the other was reached in 74%. This recommendation is made for cross-sectional studies but not for examinations of clinically suspicious cattle herds.
