Postabortal infectious morbidity after antibiotic treatment of chlamydia-positive patients.

The postabortal infection rate in chlamydia-positive women after antibiotic treatment (doxycycline or erythromycin) was compared with infectious morbidity among untreated culture-positive women in a comparable previous study. Of 69 chlamydia-positive patients, 5 (7.2%) developed endometritis and one (1.4%) salpingitis during the first postoperative month. The corresponding figures during the previous regimen were 16 (23.2%) and 10 (14.5%), respectively, i.e. a highly significant decrease (P less than 0.001). The infection rate among the chlamydia-negative women was unchanged. It is suggested that preoperative screening for C. trachomatis should precede legal abortion. Initiation of treatment of culture-positive cases before or at least in conjunction with the abortion seems to reduce the risk of infectious complications to the same level as in chlamydia-negative women.

The influence of sexual and social factors on the risk of Chlamydia trachomatis infections: a population-based serologic study.

BACKGROUND: Genital chlamydia infections often are asymptomatic, which promotes their spread in the population. In women, the possible consequences of infection are pelvic inflammatory disease and infertility. Most studies on the prevalence of Chlamydia trachomatis have been based on clinical series, and prevalences tend to vary with the clinical setting. Few seroepidemiologic studies have emerged from industrialized countries. GOAL OF THIS STUDY: To assess the prevalence of Chlamydia trachomatis using culture and serology, and its relationship with possible risk factors. STUDY DESIGN: This was a population-based study involving completion of a self-administered questionnaire, analysis of cervical samples for Chlamydia trachomatis, and serologic tests for Chlamydia trachomatis antibodies. RESULTS: The prevalence of Chlamydia trachomatis infection was 2.7%, and the seroprevalence was 24.7% among the sexually active women. Seropositivity was correlated with sexual behavior variables, and the incidence of serologic cross-reactivity with respiratory infections (strain TWAR) was low. Multivariate logistic regression analysis showed the number of sexual partners, age at first coitus, history of therapeutic abortion, and previous pelvic inflammatory disease to be independently correlated with seropositivity. CONCLUSION: Early sexual experience and multiple lifetime sexual partners are independent risk factors for Chlamydia trachomatis infection.

Metabolic interaction between morphine and naloxone in human liver. A common pathway of glucuronidation?

Metabolic interaction between naloxone and morphine has been studied in vitro in human liver microsomes. Morphine and naloxone are metabolized by an UDP-glucuronyl transferase to their 3-glucuronides. There is a very good correlation between the rates of formation of morphine-3-glucuronide and of naloxone-3-glucuronide. Naloxone seems to have a 10-fold higher affinity for the enzyme binding site than does morphine. Morphine and naloxone show bisubstrate kinetic patterns which appear very similar.

Contact allergy to a contaminant in Kathon CG in the guinea pig.

Kathon CG is a commercial preservative, consisting of the two active ingredients, 2-methyl-4-isothiazolin-3-one and 5-chloro-2-methyl-4-isothiazolin-3-one (5243-K-CG) and other components. 4,5-dichloro-2-methyl-4-isothiazolin-3-one (45243-K-CG) is a contaminant in Kathon CG. The chemically related active ingredients are known to be contact sensitizers in humans and guinea pigs. Aims of this study were to determine the sensitizing capacity of this contaminant and also to investigate the cross-reaction pattern by guinea pig sensitization tests. 45243-K-CG was demonstrated to be a strong sensitizer; all animals reacting to 45243-K-CG also reacted to 5243-K-CG when rechallenged.
