To compare the incidence of infective complications after transrectal ultrasonography (TRUS)-guided biopsy with either empirical fluoroquinolone or culture-based targeted antimicrobial prophylaxis, and the prevalence of fluoroquinolone resistance (FQ-R) in men undergoing prostate biopsy. A systematic review of the literature was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We included studies of patients undergoing TRUS-guided biopsy that compared infective outcomes of those who received targeted antimicrobial therapy based on the results of preprocedural rectal swab cultures, with those receiving empiric fluoroquinolone antimicrobial prophylaxis. The prevalence of FQ-R was recorded as a secondary outcome measure. Studies with no control group were excluded. From 125 studies screened, nine studies (4 571 patients) met the inclusion criteria. All studies were of cohort design, and included a combination of retrospective and prospective data. Six studies included were undertaken in North America. The remaining studies were undertaken in Spain, Turkey and Columbia. Within these studies, 2 484 (54.3%) patients received empirical fluoroquinolone prophylaxis, whilst 2 087 (45.7%) patients had pre-biopsy rectal swabs and targeted antibiotics. The mean FQ-R was 22.8%. Post-biopsy infection and sepsis rates were significantly higher in groups given empirical prophylaxis (4.55% and 2.21%) compared with groups receiving targeted antibiotics (0.72% and 0.48%). Based on these results 27 men would need to receive targeted antibiotics to prevent one infective complication. Our systematic review suggests that targeted prophylactic antimicrobial therapy before TRUS-guided prostate biopsy is associated with lower rates of sepsis. We therefore recommend changing current pathways to adopt this measure.

The purpose of this study was to determine if Neisseria gonorrhoeae; Chlamydia trachomatis; herpes simplex virus; cytomegalovirus; Epstein-Barr virus; human herpesviruses 6, 7, and 8; or adeno-associated virus influenced the production of cervical intraepithelial neoplasia. Two hundred thirty-one cervical smear samples were tested for the presence of the organisms by PCR. In addition, human papillomavirus types in the samples were determined by PCR and classified into cancer risk types of high, moderate, and low. There was no link with cervical intraepithelial neoplasia status and detection of herpes simplex virus, cytomegalovirus, EpsteinBarr virus, human herpesviruses 6 and 8, gonorrhea, or chlamydia. However, high-grade cervical intraepithelial neoplasia was found more frequently with mixed infection by moderate-risk human papillomavirus types and human herpesvirus 7 than with these papillomavirus types alone. The presence of human herpesvirus 7 may increase the oncogenic potential of moderate-risk human papillomavirus types.
