This review focuses on typical and atypical manifestations of neurosyphilis. The manifestations of neurosyphilis are manyfold and may involve many specialties. Today, clinicians have limited experience with the well-described manifestations of neurosyphilis. Many screening opportunities for men who have sex with men might catch the majority of cases of syphilis in this group. However, a concern could be if disclosure about heterosexuality or, in general, monosymptomatic neurosyphilis constitute a risk for delayed diagnosis.

Mycoplasma genitalium (MG) is a common cause of nongonococcal cervicitis and urethritis. We investigated the demographic and clinical characteristics of patients tested in Denmark with the Conformité Européenne (CE)/in vitro diagnostics (IVD) Aptima Mycoplasma genitalium assay (CE/IVD AMG; Hologic) and examined the clinical significance of the higher sensitivity of the TMA-based MG assays. From March to June 2016, urogenital and extragenital specimens from consecutive attendees at a sexually transmitted infection clinic in Copenhagen, Denmark were tested with the CE/IVD AMG assay (TMA-based), the research-use-only MG Alt TMA-1 assay (Hologic), a laboratory-developed TaqMan mgpB quantitative real-time PCR (qPCR), and the Aptima Combo 2 (CT/NG; Hologic). Demographic characteristics and clinical symptoms were collected from the patient records. There were 1,245 patients included in the study. The MG prevalence among female subjects was 9.4%, and the MG prevalence among male subjects was 8.7%. Compared to the TMA-based assays, the sensitivity of the PCR-based MG assay was 64.52%, and 55 specimens from 48 individuals were missed in the mgpB qPCR. Of these, 26 individuals (54.2%) were symptomatic, whereas, among 64 individuals with concordant results, 30 individuals (46.9%) were symptomatic; no statistically significant difference was found between the groups (P = 0.567). The improved sensitivity of the TMA-based assays resulted in diagnoses of more patients with clinically relevant symptoms for which antibiotic treatment is indicated. However, approximately half of the MG-infected patients reported no symptoms, and future research is needed to investigate the pros and cons of diagnosing and treating MG in asymptomatic subjects.

Background Kidney transplant recipients (KTRs) have increased risk of human papillomavirus (HPV)–related anogenital (pre)cancers, including anal high-grade intraepithelial lesions and cancer. Previous studies on anal high-risk HPV (hrHPV) among KTRs are sparse. Methods In a cross-sectional study, we included 247 KTRs and 248 controls from a dermatology department and 5 nephrology departments in Denmark during 2016–2017. All participants provided an anal cytobrush sample that was tested for HPV DNA. Participants completed a questionnaire on lifestyle and sexual habits. We used logistic regression to estimate odds ratios (ORs) of anal hrHPV in KTRs compared with controls and risk factors for anal hrHPV in KTRs. Results The anal hrHPV prevalence was higher in female KTRs (45.5%) than in controls (27.2%). Female KTRs had almost 3-fold higher adjusted odds of anal hrHPV than controls (adjusted OR, 2.87 [95% confidence interval, 1.57–5.22]). In contrast, among men we did not observe increased prevalence or odds of anal hrHPV in KTRs compared with controls (prevalence, 19.4% vs 23.6%; adjusted OR, 0.85 [95% 95% confidence interval, .44–1.64]). Among hrHPV-positive KTRs, 63% and 52% of men and women, respectively, were infected with hrHPV types covered by the nonavalent HPV vaccine (type 16, 18, 31, 33, 45, 52, or 58). Current smoking, >10 lifetime sexual partners, history of genital warts, and among men having had receptive anal sex were risk factors for anal hrHPV in KTRs. Conclusions Female KTRs had an increased risk of anal hrHPV compared with immunocompetent controls. Our findings indicate that pretransplant HPV vaccination should be considered to prevent anal high-grade intraepithelial lesions and cancer caused by anal hrHPV infection in KTRs.
