Prevalent cervical HPV infection and high-risk HPV persistence consequences have been extensively investigated in the literature; nevertheless, any causative interrelations of other sexually transmitted bacterial infections (STIs) with cervical HPV infection have not yet been fully elucidated. This study aimed to investigate the possible association of STIs with cervical cytology aberrations and HPV genotyping results in a representative sample of predominantly young Greek women. Liquid-based cytology and molecular detection for bacterial STIs and HPV as well as extended HPV genotyping were simultaneously assessed in cervical samples from 2256 individuals visiting several urban outpatient Gynecology Departments for well-woman visits or cervical screening throughout a 20-month period. All specimens were centrally processed with validated molecular assays. The mean age of the studied women was 37.0 ± 11.7 years; 722 women (33.30%) tested positive for STI (mean age 34.23 ± 10.87 years). A higher mean age (38.34 ± 11.83 years (p < 0.05)) was associated with negative STI testing. Chlamydia trachomatis was detected in 59 individuals (8.2%), Mycoplasma hominis in 156 (21.6%), Mycoplasma genitalium in 14 (1.9%), and Ureaplasma spp. in 555 (76.9%); infections with two bacterial pathogens were identified in 73 samples (10.1%). Cervical HPV was detected in 357 out of 1385 samples with a valid HPV typing result (25.8%). The mean age of HPV-positive women was 32.0 ± 8.4 years; individuals testing HPV-negative were slightly older (N = 1028): 34.4 ± 9.2 (p < 0.05). Among the 1371 individuals with valid results both for bacterial STIs and cervical HPV detection, women with an HPV-positive sample were more likely to harbor an STI (OR: 2.69, 95% CI 2.10–3.46, p < 0.05). Interestingly, bacterial STI positivity illustrated significant heterogeneity between NILM and LSIL cases, with 28.88% of NILM and 46.33% of LSIL cases harboring an STI, respectively (p < 0.05). In brief, in a population with a high prevalence for STIs, especially Ureaplasma spp., an association was documented between bacterial pathogen detection and cervical HPV infection, as well as abnormal cytology; these findings merit further investigation.

A common issue is that modern obstetricians are required to manage ovarian cysts during pregnancy. Most lesions are benign and will spontaneously resolve, with a few exceptions. Management practices include conservative observation or surgery. Asymptomatic women with an ovarian cyst larger than 5 cm should undergo serial ultrasounds up to 16 weeks of pregnancy and, if the mass does not regress, further management with imaging or surgery is to be considered. This article presents a case of an ovarian cyst sized 21 cm in a second-trimester pregnancy and its management. Paracentesis was performed due to persisting symptoms. The procedure was performed with no complications for the mother and no adverse effects for the fetus. The patient was discharged in good health.

Koolen de Vries syndrome is a rare genetic disorder with an estimated prevalence 1:16000 in the general population but it is considered to be an underdiagnosed syndrome. We report a 17q21.31 microdeletion which was diagnosed prenatally in a fetus with aberrant right subclavian artery (ARSA). Koolen de Vries syndrome is a rare chromosomal abnormality and according to the literature this is the first case in which the detection of ARSA led to this syndrome.
