Human Papillomavirus (HPV) infection is known to be associated with a number of conditions including cervical, vaginal, vulvar, penile, anal neoplasias and cancers, oropharynx cancers and genitals warts (GW). Two prophylactic vaccines are currently available: a bivalent vaccine designed to prevent HPV type 16 and 18 infection and a quadrivalent vaccine targeting HPV 6, 11, 16, and 18. In France, HPV vaccination is recommended in 11-14 year-old girls with a catch-up for girls aged 15-19. The objective of this study was to assess the potential impact of an HPV 6/11/16/18/31/33/45/52/58 nonavalent vaccine on anogenital and oropharyngeal HPV-related diseases in France. HPV genotype distributions from 6 multicentric retrospective studies (EDiTH I to VI) were analyzed including 516 cases of invasive cervical cancers (ICC), 493 high-grade cervical neoplasias (CIN2/3), 397 low-grade squamous intraepithelial lesions (LSIL), 423 GW, 366 anal cancer and 314 oropharyngeal carcinomas. Low and high estimates of HPV vaccine impact were calculated as follows: low estimate: prevalence of HPV 6/11/16/18/31/33/45/52/58 genotypes alone or in association but excluding presence of another HPV type; high estimate: prevalence of HPV 6/11/16/18/31/33/45/52/58 genotypes alone or in association, possibly in presence of another HPV type. Estimates of potential impact varied from 85% (low estimate) to 92% (high estimate) for ICC, 77% to 90% for CIN2/3, 26% to 56% for LSIL, 69% to 90% for GW, 81% to 93% for anal cancer, and 41% to 44% for oropharyngeal carcinomas. Compared to the quadrivalent vaccine, the proportion of additional cases potentially prevented by the nonavalent vaccine was 9.9%-15.3% for ICC, 24.7%-33.3% for CIN2/3, 12.3%-22.7% for LSIL, 2.1%-5.4% for GW, 8.5%-10.4% for anal cancer, and 0.0%-1.6% for oropharyngeal carcinoma. The nonavalent HPV vaccine showed significant increased potential impact compared to the HPV 6/11/16/18 quadrivalent vaccine for ICC, CIN2/3 and LSIL. Considering a 100% vaccine efficacy and high vaccine coverage, about 90% of ICC, CIN2/3, GW or anal cancer cases could be prevented by a nonavalent HPV vaccine in France.

High-risk HPV (hrHPV) testing has been implemented as a primary screening tool for cervical cancer in numerous countries. However, there is still a need for relevant triage strategies to manage hrHPV positive women to avoid excessive referral to colposcopy. The objective of this study was to assess, in women infected by hrHPV and presenting no or mild cytological abnormalities, HPV16 and HPV18 viral loads to predict the development of cervical high-grade lesion. Among 2102 women positive for hrHPV, 885 had no lesion or mild cytological abnormalities at baseline and had at least one follow-up (FU) visit. HPV16 and HPV18 prevalence was 25.9% and 8.4%, respectively. Of those women, 15% developed a high-grade lesion during the FU. An HPV16 viral load cut-off set at 3.2 log10GE/103 cells permitted to identify a subgroup of women at high risk of developing high-grade cervical lesion (HR = 2.67; 95% CI 1.80–3.97; p ≤ 0.0001). No specific HPV18 viral load threshold could have been defined in regard to the present study. In multivariate analysis, HPV16 load (absence/log10GE/103 cells < 3.2 vs. ≥3.2), RLU/PC 239 (1–100 pg/mL vs. >100 pg/mL) and cytology (normal vs abnormal) were independently associated with a significant increased risk of high-grade lesion development and were used to construct the prognostic score. In conclusion, HPV16 load is a relevant biomarker to identify women at high risk for developing cervical precancerous lesions.

Adenoid cystic carcinoma of Bartholin's gland is a very rare disease. A 48-year-old premenopausal woman of Caucasian origin was delivered adjuvant pelvic and inguinal radiotherapy after prior complete left Bartholin's gland tumor excision and inguinal lymph node dissection for adenoid cystic carcinoma of Bartholin's gland with one metastatic inguinal lymph node.Two years after primary treatment, she presented to the Emergency Room with acute headache, hypoacousia, decrease in visual acuity, and a decrease in right leg muscle strength. A cranial magnetic resonance imaging scan demonstrated three cystic brain lesions with associated perifocal edema. Chest and abdomen computed tomography scans and a magnetic resonance imaging scan of the pelvis did not find any metastatic or residual disease elsewhere. A physical examination found no local recurrence.Stereotactic brain biopsies with pathology examination revealed the presence of adenoid cystic carcinoma metastasis. She thus received 30Gy of brain radiotherapy but, three months later, the brain lesions did not decrease in size and left mid lobular lung lesions appeared on her chest computed tomography scan. A mid left lobe lung excision was undertaken followed by chemotherapy consisting of six cycles of cyclophosphamide, adriamycin and cisplatin. Five months after beginning chemotherapy, the brain disease progressed and our patient died. Our case report shows the difficulty in managing brain and lung metastasis of Bartholin's gland adenoid cystic carcinoma as no consensus on the optimal treatment exists.

Evaluate the feasibility of active delivery of the anterior arm during spontaneous delivery. This maneuver could decrease incidence of second-degree perineal tears because it reduces fetal biacromial diameter. An observational comparative prospective study was conducted at our teaching maternity from July 2012 to March 2013. The study included 199 nulliparous women ≥18 years, who met the following criteria: singleton pregnancy, vaginal delivery with occiput anterior presentation, on epidural analgesia, from 37 weeks of gestation onward. The distribution of rate and type of perineal tears were compared between two groups: a non-exposed group and a group exposed to the maneuver. A total of 101 patients were exposed to Couder’s maneuver (CM) and 98 patients were not exposed. In the intervention group, 3 failures of the maneuver were reported. The maneuver was considered easy in 80% of cases, moderately easy in 12% and difficult in 8% of cases. There was a significant difference (p = 0.03) in the distribution of perineal tears between the two groups. There was a significant reduction (p < 0.001) in the number of second-degree perineal tears in the patients exposed to CM. There was no significant difference in the rate of anterior perineal trauma between the exposed and non-exposed arms. CM in primiparous women at term is feasible with a low failure rate and influences the distribution of perineal tears by lowering second-degree perineal tears in a highly significant manner (p <0.01).
