Congenital hydrocephalus was once a permanently disabling and even fatal disease. With the advent of ventriculoperitoneal shunts, affected women are now surviving to their reproductive years and beyond. Pregnancy outcomes in this population are generally positive. However due to possible shunt complications, including infection, migration, and organ perforation, perinatal care for pregnant individuals with a ventriculoperitoneal shunt is complex and requires input from both obstetric and neurosurgical providers. We present the case of a 28-year-old G1P1 with a history of congenital hydrocephalus and ventriculoperitoneal shunt who presented to the emergency department at two months postpartum with clear fluid leaking from her vagina. The shunt's distal end had migrated and perforated the uterus causing cerebrospinal fluid to leak into the uterine cavity. Surgical repair was required of both the uterine hysterotomy and ventriculoperitoneal shunt, and the patient's symptoms ultimately resolved. Patients with a history of shunt placement who later undergo abdominal surgery, including cesarean section, are at risk for shunt complications. Shunt-dependent patients presenting in the post-partum period with new neurological or abdominopelvic complaints should undergo evaluation by a multidisciplinary team.

A safe and non-intrusive assessment of fetal health is not only crucial in low-risk gestations, but it is also the standard of care in high-risk pregnancies. Therefore, measuring blood flow across different vessels with non-invasive ultrasound methods has been accurately and painstakingly studied and published. Amongst these state-of-the-art techniques, umbilical artery (blood flow) Doppler velocimetry (UADV) has allowed for fetal well-being follow-ups and assess uteroplacental function, which obtains a more complete and clearer picture; particularly in regard to complicated pregnancies. Additionally, there are other modalities with diverse clinical applications that have emerged, including their clinical and research utilization in conditions such as fetal growth restriction (FGR), preeclampsia, fetal anemia, monochorionic twins vascular blood flow mismatch such as is in twin-to-twin transfusion syndrome, twin anemia polycythemia sequence, and twin reverse arterial perfusion sequence. Nevertheless, their applications regarding various other maternal-fetal diagnoses in the same way as premature births and/or multiple gestation surveillance have not been reported to hold strong clinical evidence. With that in regard, the purpose of this unique study was to give update of the multiple clinical applications of this very important obstetrical tool. Additionally, to review the pathophysiology as well as revisit their reported significant valid uses and occasional overuses. We also delved into quality control measures as related to the application of Doppler in obstetrics. Lastly, it is essential to look through and reflect on the future developments of this valuable, non-invasive, high-risk marvelous modern device.

Background: We aimed to assess procedure-related risk of fetal loss associated with amniocentesis and chorionic villus sampling and compare amniocentesis and chorionic villus sampling with cell-free fetal DNA in identifying chromosomal abnormalities.

Methods: A retrospective observational study on 4712 women with singleton pregnancy who underwent invasive prenatal diagnosis, from January 2010 to December 2019. Postprocedural miscarriage rate (before 24⁺⁰ weeks gestation) was determined for the whole population and for the group of women aged ≥35 years who underwent the procedure for the sole maternal age.

Results: Miscarriage rate following amniocentesis and chorionic villus sampling were 0.50% and 1.25%, respectively. In our population of women undergoing invasive procedure for advanced maternal age cell-free fetal DNA would have identified only the 49 cases of trisomy 21, 13 and 18, whereas the other 21 more subtle chromosomal anomalies, diagnosed by amniocentesis and chorionic villus sampling, would have been missed.

Conclusions: Patients who opt for cell-free fetal DNA test should be informed of the screening nature of the test and the possibility of false positive results. Invasive prenatal testing has probably lower risks than previously reported and has unquestionable advantages such as the certainty of diagnosis and the ability to detect a higher number of chromosomal abnormalities, when compared with cell-free fetal DNA.

Background: The genomic approach has deeply changed the microbiology perspective, mainly concerning the microbioma identification. In this regard, some microbes colonize the healthy vagina. Vaginitis is a common gynecological ailment and includes bacterial vaginosis (BV), usually caused by local dysbiosis, such as a microbiota imbalance. Lactobacilli are the most prevalent bacteria colonizing the healthy vagina, so guaranteeing local eubiosis. In particular, vaginal colonization by L. crispatus is associated with low susceptibility to BV. Therefore, probiotics, such as life bacteria providing health advantages, are a current strategy in the prevention or treatment of vaginitis, including BV. However, there is a low level of evidence that probiotics after ingestion could really colonize the vagina. In particular, no study evidenced that L. crispatus after ingestion can colonize vagina. Therefore, the current study explored the capacity of Biovaginil^® (NTC, Milan, Italy) dietary supplement containing Lactobacillus crispatus NTCVAG04 and vitamin A to colonize the gut and vagina in women with a history of vaginitis/vaginosis.

Methods: Twenty fertile females (mean age 34.0 years) were enrolled in the study. Rectal and vaginal swabs were collected at baseline and after the first and second cycle of Biovaginil^®. Each cycle lasted 14 days within two consecutive menstrual periods.

Results: Seven women were excluded from the analysis because the samples were technically not evaluable. One woman dropped out because of mild adverse event. At the end of the study, nine women (75%) had positive rectal swab for L. crispatus NTCVAG04, and 8 of them also had positive vaginal swab.

Conclusions: The current study provided the first evidence that L. crispatus NTCVAG04, administered by two Biovaginil^® courses, colonized both the gut and vagina. Moreover, the L. crispatus NTCVAG04 strain could be considered the archetype of a new class of oral probiotics that actively colonize the vagina, and that could be called "colpobiotics."

Background: Pharmacovigilance agencies did not collect data regarding menstrual changes after COVID-19 vaccination even if many women experienced it. Our aim was to evaluate whether COVID-19 vaccination is associated with secondary changes in menstrual cycle and to assess both quality of life (QoL) and sexual function (SF).

Methods: This study is a retrospective analysis referred to our Department from January 2021 to December 2021. The study cohort responded to same questionnaires before the second dose of vaccination (referring to previous 3 months) and 3 months after that (referring to three menstrual cycles after full-dose vaccination). The surveys administered were FSFI, FSDS, SF-36, MEDI-Q and the VAS-scale for dysmenorrhea.

Results: Four-hundred-nineteen vaccinated women were included in the study. The survey did not show a significant change in menstrual cycle length before and after COVID-19 vaccine (5.88±3.67 vs. 4.97±2.89, P=0.21); the interval between periods was significantly higher after a full-cycle vaccination (28.32±7.34 vs. 32.38±7.45, P<0.02); 32 patients (7.6%) developed amenorrhea after the second dose; VAS Scale did not change significantly (median range 3 (3-5) vs. 4 (3-6), P=0.20). MEDI-Q did not show significant variations before and after the vaccination (43.21±11.65 vs. 40.28±9.88, P=0.35). QoL and SF did not change significantly (FSFI median 27 [24-29] vs. 28 [25-30], P=0.12, FSDS median 9 [5-11] vs. 8 [4-12], P=0.22), SF-36 median 81 [70-85] vs. 82 [72-86], P=0.43).

Conclusions: COVID-19 vaccination is associated with a significant change in intervals between menstrual cycles without other alterations in menstrual characteristics, in QoL or SF.

Female genital mutilation/cutting (FGM/C or FGM) are injuries to the female genital organs for non-medical reasons. Every year, over 4 million girls are at risk of FGM. Complications of this practice are very common and some of them are still under investigation. The purpose of this short narrative review is to highlight and summarize the main ones. Psychologic and psychiatric sequelae, chronic vulvar pain, urogenital symptoms, pelvic organs prolapse, sexual disfunction, cervical dysplasia and infections resulted as chronic sequalae of FGM. Severe pain, excessive bleeding, and tissues swelling are acute consequences of FGM. Rates of caesarean section, time of second stage of delivery, post-partum blood loss (but not major hemorrhage), peri-clitoral and perineal injuries and episiotomy rates are higher in pregnant women with FGM, when compared with those non victims of mutilation. The female genital mutilation practice is often cause of severe urogynecologic, psychologic and obstetrics sequelae. Although several studies have been carried out on FMG complications and treatments, long term sequelae are still very common and deserve major attention and further research.

Background: Infertile women carrying ovarian endometriomas can be managed either with surgery or by in-vitro fertilization (IVF). The aim of this study was to compare ovarian responsiveness to controlled ovarian stimulation (COS) in assisted reproduction techniques (ART) in infertile women carrying small intact endometriomas and those managed by endometrioma cystectomy or CO2 fiber laser ablation.

Methods: Retrospective case-control study of prospectively collected data including women underwent ART for endometriosis-related infertility. The study group consisted of infertile women undergoing endometriomas CO2 fiber laser vaporization before ART ("ART after laser CO2" group). Controls were infertile women with endometrioma managed by cystectomy before ART ("ART after cystectomy" group) and infertile women with small endometriomas undergoing ART as first approach ("ART only" group).

Results: Of the 86 included patients, 27 (31.4%) belonged to "ART after laser CO2" group, 37 (43%) to "ART after cystectomy" group and 22 (25.6%) to "ART only" group. Surgical groups had larger endometriomas than patients referred to "ART only" group. No between-groups differences were observed in terms of COS protocol, gonadotropins starting and total doses and length of COS. While women belonged to "ART after cystectomy" group had fewer recruited follicles (P=0.014), oocytes (P=0.042), MII oocytes (P=0.042) and formed embryos (P=0.004) compared to women of "ART only" group, no significant differences were found between patients of "ART only" group "ART after laser CO2" group. A greater number of good-quality embryos were observed in surgical groups. No between-groups differences were found in clinical pregnancy rates.

Conclusions: Our results demonstrate encouraging findings on IVF/ICSI outcomes after laser CO2 endometrioma ablation in terms of both quantity and quality of developed embryos.

Background: Anogenital distance (AGD) is affected by intrauterine biochemical exposure. AGD appears to be associated with intrauterine testosterone level. It was aimed to explain the relationship between AGD and women's sexual quality of life.

Methods: A total of 600 participants were included in the study, 200 of whom did not give birth, 200 who had a normal vaginal delivery, and 200 who had a cesarean section. Hormone levels on the third day of their period, age, and BMI were recorded. AGD measurements were made and compared with the Female Sexual Function Scale (FSFI) and The Sexual Quality of Life-Female (SQOL-F) scores.

Results: AGD and serum testosterone level appear to be unrelated. SQOL-F scores were statistically significantly correlated with AGD-AC and AGD-AF in all women (r=0.66 and r=0.84, respectively); FSFI scores were statistically significantly correlated with AGD-AC and AGD-AF in all women (r=0.66 and r=0.85, respectively) regardless of birth status.

Conclusions: Female sexual life is associated with AGD determined in the womb. However, further studies are needed to confirm our results.
