Bivalent human papillomavirus (HPV) vaccine was incorporated into the childhood vaccination calendar in Galicia, Spain in 2008. The objectives of this study were to estimate direct, indirect and total effectiveness of HPV vaccine and to identify sexual habits changes in the post-vaccination period in Galicia, Spain.Endocervical scrapings of 745 women attending 7 Health Areas of the Galician Public Health Service were collected in the post-vaccination period, from 2014–2017. Two groups were studied: women born between 1989 and 1993 (n = 397) and women born in 1994 or later (n = 348). Twelve high-risk human papillomavirus (HR-HPV) genotypes were detected by Cobas® 4800 HPV test (Roche Diagnostics, Mannheim, Germany). The Linear Array® HPV Genotyping Test (Roche Diagnostics) was used for HR-HPV genotype detection other than HPV 16/18. Information about sexual habits was collected by a self-filled questionnaire. Post-vaccination data were compared to previously published pre-vaccination data obtained between 2008 and 2010 in Galicia from women of the same age (18–26 years old, n = 523). The Stata 14.2 software was employed for statistical analyses.Data from 392 unvaccinated and 353 vaccinated women were compared. For unvaccinated and vaccinated women, HPV 16/18 prevalence was 9.2% and 0.8%, respectively, and HPV 31/33/45 prevalence was 8.4% and 1.1%, respectively. Direct, indirect and total effectiveness of the HPV vaccine were (%, 95% CI): 94 (72−99), 30 (-11−56) and 95 (79−99), respectively, for HPV 16/18 and 83 (46−94), -10 (-88−33) and 84 (54−94), respectively, for HPV 31/33/45. The number of women with first intercourse before 17 years old and 3 or more sexual partners along life was higher in the post-vaccination period (p < 0.05). A positive impact of bivalent HPV vaccine was observed, both on direct and cross protection. Sexual habits could have changed in the post-vaccination period.

Objective: To determine whether, in addition to treatment with antibiotics, it is necessary to remove the intrauterine device (IUD) to eliminate genital colonization by Actinomyces. Methods: A randomized clinical trial was carried out. Patients were divided into two groups. The intervention group did not have their IUDs removed, while the control group did. Both groups were treated with trimethoprim and sulfamethoxazole. A total of 43 patients were included. Results: The patients from the intervention group and the control group proved to be comparable. The post-intervention cytology smear tested negative for Actinomyces in 100% of the patients whose IUD had been removed and in 66.7% of those whose IUD had not been removed (p = 0.005). The probability that colonization by Actinomyces will continue if the IUD is not removed is greater the longer the patient has been exposed to the IUD. After 24 months, relative risk (RR) = 2, after 36 months RR = 2.16 and after 48 months RR = 2.66. Conclusions: The removal of the IUD has been effective in genital colonization by Actinomyces. The protective effect exerted by the removal of the IUD was found to be greater in proportion to the length of time the patient had used it.

It is concluded that retroflexion of the uterus increases the probability of removal.
