Horizons in Endometriosis: Proceedings of the Montreux Reproductive Summit, 14-15 July 2023.

Endometriosis is a complex and chronic gynaecological disorder that affects millions of women worldwide, leading to significant morbidity and impacting reproductive health. This condition affects up to 10% of women of reproductive age and is characterised by the presence of endometrial-like tissue outside the uterus, potentially leading to symptoms such as chronic pelvic pain, dysmenorrhoea, dyspareunia, and infertility. The Montreux summit brought a number of experts in this field together to provide a platform for discussion and exchange of ideas. These proceedings summarise the six main topics that were discussed at this summit to shed light on future directions of endometriosis classification, diagnosis, and therapeutical management. The first question addressed the possibility of preventing endometriosis in the future by identifying risk factors, genetic predispositions, and further understanding of the pathophysiology of the condition to develop targeted interventions. The clinical presentation of endometriosis is varied, and the correlation between symptoms severity and disease extent is unclear. While there is currently no universally accepted optimal classification system for endometriosis, several attempts striving towards its optimisation - each with its own advantages and limitations - were discussed. The ideal classification should be able to reconcile disease status based on the various diagnostic tools, and prognosis to guide proper patient tailored management. Regarding diagnosis, we focused on future tools and critically discussed emerging approaches aimed at reducing diagnostic delay. Preserving fertility in endometriosis patients was another debatable aspect of management that was reviewed. Moreover, besides current treatment modalities, potential novel medical therapies that can target underlying mechanisms, provide effective symptom relief, and minimise side effects in endometriotic patients were considered, including hormonal therapies, immunomodulation, and regenerative medicine. Finally, the question of hormonal substitution therapy after radical treatment for endometriosis was debated, weighing the benefits of hormone replacement.

COVID-19 reinfection after pregnancy.

BACKGROUND: There have been reports of COVID-19 reinfections, but the immunological characterization of these cases is partial. We report a case of reinfection with SARS-CoV-2, where the first infection occurred in the course of late pregnancy. CASE PRESENTATION: On May 27, 2020, a 37-year-old woman gave birth at full term, 3 hours after full dilatation. She developed fever (38.3°C) after delivery. Mild biological anomalies compatible with COVID-19 were observed: lymphopenia, thrombocytopenia, elevated D-Dimers, CRP, and LDH. At 6-month follow-up, she reported having contracted COVID-19 with high fever, rhinorrhea, hand frostbites, cough, headache, dysgeusia and anosmia. CONCLUSIONS: We report a case of COVID-19 reinfection with a first mild infection during late pregnancy and a more aggressive second infection 5 months later.

[Uterus transplantation, current prospect and future indications. State of art with review of literature]. / La transplantation utérine : essor de la technique chirurgicale, nouvelles indications. État de l'art avec revue de la littérature.

OBJECTIVES: The aim of this review is to summarize the development of UT on worldwide and to develop the new questions posed by this technique in 2020. METHODS: According to the PRISMA model, via Pubmed, we searched for publications containing the keywords: uterus transplantation; UT and cryopreservation from 2000 to 2020. RESULTS: At least 76 UTx have been carried out around the world and 19 healthy babies were born. The main indication remains the uterine agenesis (MRKH Syndrome>85% cases) then the history of hysterectomy (hemorrhage of the delivery or cervical cancer) and the non-functional uterus (Asherman's syndrome, diffuse adenomyosis). The 2 types of donors (living and deceased) are developed representing respectively 75% and 25% of the TU; the success rate in terms of return of rules is better in the living donor group and is 79% vs 68% in the deceased donor group. The choice of donor type must take into account the constraints of both procedures. Surgical complications (grade III) for the donor are estimated to be 14% mainly represented by ureter wounds. Technical simplifications concerning the venous return of the graft but also the carrying out of robot-assisted surgery would reduce the operating time for the donor and facilitate the collection process. CONCLUSION: TU is a complementary alternative to GPA and adoption allowing patients to be surrogates, legal and biological of the baby. An extension of the indications to patients with non absolute uterine infertility is in the process of democratization.

Improving safety of preparation and administration of medicines and enteral nutrition in a neonatal care unit: Global risk analysis.

OBJECTIVE: To date, few adapted pharmaceutical forms are available for infants leading to multiple steps of preparation and medicines dilution before administration. The main purpose of this study was to assess the risks on the steps of preparation and administration of medicines in a neonatal care unit and to propose corrective actions to ensure the medicines safety. METHODS: A global risk analysis was performed, conducted by a multidisciplinary working group of 9 experts, that is 9 meetings. RESULTS: We identified 57 scenarios: 59,6% of scenarios had an initial criticality C1, 31,6% C2 and 8,8% C3. The most risky phases were phases of needs identification including the step of doses calculation and phases of preparation. The strategic management together with the human factor were the most risky dangers. Nineteen corrective actions were proposed. After implementing those actions, 82,5% of scenarios had residual criticality C1, 17,5% C2 and no scenario had residual criticality C3. Follow-up actions have been implemented to control the residual risk as in service training. CONCLUSION: Neonatal unit care is a risky service and should be a priority in the risk management policy. This analysis joins the quality policy implemented in the hospital and similar risk analysis is on process.

[Assessment of pelvic floor muscle training programs and urinary incontinence in women: A literature Review]. / Évaluation des programmes d'entraînement musculaire du plancher pelvien et incontinence urinaire chez la femme : revue de la littérature.

OBJECTIVES: Pelvic floor rehabilitation is efficient for the first line treatment of urinary incontinence in women. However, several questions remain as regards the best pelvic floor muscle training program to recommend. The objective was perform a literature review regarding the muscular strengthening program to recommend to treat stress or mixed urinary incontinence in women. METHODS: We performed a systematic review of studies on the topic using Medline's database covering the 10 last years. Among the 1130 articles that were identified, we retained 6 for our analysis. RESULTS: Given the heterogeneity of the exercise programs, it was impossible to exhaustively and comparatively analyze their efficacies. However, a significant improvement is noted when the exercises are based on the muscular training principles of the American College of Sports Medicine. They combine long and short contractions with the practice of the knack in situations of pressure exertion and are part of a self-rehabilitation program based on the needs of the patient and the individual's progression. CONCLUSION: Current knowledge does not allow us to recommend an optimal muscle training program to treat female urinary incontinence. Research must be conducted to evaluate different muscular training regimens but also their integration into a program based on personal needs as well as factors of adherence to the treatment of patients.

Determination of rubella virus-specific humoral and cell-mediated immunity in pregnant women with negative or equivocal rubella-specific IgG in routine screening.

BACKGROUND: Immunity to rubella-virus (RV) is commonly determined by measuring specific IgG (RV-IgG). However, RV-IgG results may be different and even discordant, depending on the assay used. Cell-mediated immunity is not routinely investigated for diagnostic purposes. OBJECTIVES: Our aim was to investigate humoral and cellular immunity of women with negative or equivocal RV-IgG before, and after post-partum vaccination. STUDY DESIGN: A total of 186 pregnant women were included in the study. During pregnancy, humoral immunity was investigated with two RV-IgG immunoassays, an immunoblot and a T-cell mediated immunity test. In the post-partum vaccination period, measuring RV-IgM and RV-IgG avidity allowed us to determine whether women raised a primary or a secondary immune response. RESULTS: Before vaccination, 52.2% women, supposed to be susceptible, had positive anti-E1 RV-IgG indicating strong evidence of previous exposure to RV. All (100%) pregant women who had a positive immunoblot before immunization raised a secondary immune response to vaccination, and 96.8% who had a negative immunoblot before immunization, raised a primary immune response to vaccination. All women who raised a primary immune response after vaccination had negative anti-E1 RV-IgG and negative cell-mediated immunity. DISCUSSION: These results indicate that individuals can have evidence of protective immunity against rubella despite negative RV-IgG.

Risk factors and management of persistent postpartum urinary retention.

INTRODUCTION AND HYPOTHESIS: Our objective was to identify the risk factors for persistent postpartum urinary retention (PUR). MATERIAL AND METHODS: This multicenter retrospective case-control study included 91 women with PUR exceeding 400ml during the first urinary catheterization performed after delivery, from 2010 through 2015. Two groups were defined: one included 25 women with PUR that persisted longer than 3 days, and the other, comprising 66 women with PUR that lasted three days or less. We compared the two groups to define the risk factors. We also studied the outcome of the women with persistent PUR. RESULTS: The time until diagnosis/management and the urinary volume at the first catheterization after delivery were both significantly greater in the group with persistent PUR (11h vs 7.8h and 1020ml vs 715ml, P<0.05). Multivariate logistic regression indicated that cesarean delivery, perineal tear or episiotomy, and fluid administration in the delivery room were also associated with the persistence of PUR (P<0.05). CONCLUSION: Time in the management of urinary retention can cause bladder overdistension that can substantially delay its resolution. More attentive monitoring of voiding, could reduce the duration of this complication and thereby improve patient comfort and minimize long-term complications. BRIEF SUMMARY: This multicenter retrospective study show that the time in the management of urinary retention is a major factor of persistent urinary retention.

Adverse effects of maternal enterovirus infection on the pregnancy outcome: a prospective and retrospective pilot study.

BACKGROUND: Enteroviruses account for about one billion infections worldwide each year, the majority remain asymptomatic. Data on enterovirus infections during pregnancy appear to be very rare. Several cases have been reported in the literature of fetal and neonatal complications attributed to these viruses, but prospective data on these infections during pregnancy are not available. OBJECTIVE: To estimate the prevalence of enterovirus infections in febrile syndromes in pregnant women, and in case of in utero fetal death (IUFD). METHODS: Ttri-centric observational cohort study. We performed prospective inclusion for patients with fever during a four-month period. We also analyzed the amniotic fluid in patients with unexplained IUFD retrospectively during a five-year period. Investigations of enteroviruses are made by RT-PCR from routine biological samples (amniocentesis, RT-PCR in maternal blood or CSF). RESULTS: Prospectively, 33 patients were included during the study period. We have identified 4 cases of confirmed enterovirus infection (12.4%). We have recorded a severe form of perinatal enterovirus infection involving the vital prognosis of the newborn. In the retrospective cohort of 75 IUFD cases, we had only one case of enterovirus-positive RT-PCR in amniotic fluid during 5 years, meaning a frequency of 1.3%. We did not had any positive EV case in case of early miscarriage, but the limited number of inclusions cannot help us to conclude. CONCLUSION: Enteroviruses are probably an underestimated cause of obstetric and neonatal complications. Investigation of enterovirus by PCR should be discussed during pregnancy and peripartum in case of febrile syndrome with no obvious bacterial cause, and unexplained IUFD.

Uterine transplantation: Review in human research.

Uterine transplantation is the solution to treat absolute uterine fertility. In this review, we present the historical, medical, technical, psychological and ethical perspectives in human uterine transplantation research. We reviewed the PubMed database following PRISMA guidelines and added data presented by several research teams during the first international congress on uterine transplantation.

[Comparative study about enhanced recovery after cesarean section: What benefits, what risks?] / Étude comparative sur la réhabilitation améliorée postcésarienne : quels bénéfices, quels risques ?

OBJECTIVE: The post-caesarean enhanced recovery protocol's goal is to allow a quick recovery of previous physical capabilities and increase the chances of an early release and return to normal activities. METHODS: At the Foch Hospital, we performed a case control survey including 2 consecutive groups of patients. The first group was composed of 83 patients that experienced the regular post c-section treatment and the second group of 84 patients that benefited from the enhanced recovery treatment. The characteristics of both groups were comparable. We monitored the complications, hospitalization time and full recovery time for each group. RESULTS: The average hospitalisation time for the patients that received the enhanced recovery treatment was significantly lower than for those that received the standard treatment (3,92 days vs 4,34 days P<0,01). The autonomy for the toilet and the mobility was improved. The average number of complications was not greater for the enhanced recovery group, except for acute retention of urine which were all treated with a simple urine sample return. CONCLUSION: The post-cesarean enhanced recovery seams to allow the significant improvement in recovery of autonomy and length of hospitalization stay without increasing significantly the rate of complications except for the acute retentions of urines which involve in postpartum period close monitoring patients' urination.

[Enterovirus infection during pregnancy: Underestimated cause of fetal and neonatal complications?] / L'infection à entérovirus durant la grossesse : une cause sous-estimée de complications fœtale et néonatale ?

Enteroviruses are responsible for about one billion infections every year in the world. The clinical expression is in the vast majority asymptomatic cases (90%). Its consequences during pregnancy are rarely described. From the Medline database, we selected and analyzed 34 articles ranging from 1965 to 2015, to analyse the current knowledge of enterovirus infection consequences during pregnancy. We found that enterovirus infections may be the cause of fetal loss. The enterovirus infections during the 2nd and 3rd trimester may also lead to in utero fetal anomalies and death, but also to severe neonatal infections. PCR enterovirus detection should be performed during pregnancy and the peripartum in case of unexplained fever, specific fetal anomalies or unexplained fetal demise.

Uterus transplantation in France: for which patients?

OBJECTIVE: Uterine infertility (UI), which can be caused by a variety of congenital or acquired factors, affects several thousand women in Europe. Uterus transplantation (UTx), at the current stage of research, offers hope for these women to be both the biological mother and the carrier of their child. However, the indications of UTx still need to be defined. The main aim of the study was to describe the different etiologies of UI and other data as marital and parental status from women requesting UTx who contacted us in the framework of a UTx clinical trial. Secondarily, we discussed the potential indications of UTx and their feasibility. STUDY DESIGN: This is an observational study. RESULTS: Of a total of 139 patients with UI, 105 patients (75.5%) had uterine agenesis, making it the leading cause of UI in this sample. Among the patients with uterine agenesis, 25% had a solitary kidney and 44.7% had undergone vaginal reconstruction. Peripartum hysterectomy, hysterectomy for cancer, and hysterectomy for benign pathologies accounted for 9.4%, 7.2% and 5% of cases, respectively. Less common causes of UI included complete androgen insensitivity syndrome (2.2% of patients) and prenatal diethylstilbestrol exposure (0.7%). Approximately 14% of the women already had at least one child and 66% were in a couple living together for at least 2 years. CONCLUSION: UTx is still under evaluation and further research is under way. Nulliparous patients with no major medical or surgical history and with normal ovarian function, who meet the legal criteria for medically assisted reproduction, represent the best indications for UTx at this stage of its development.

Robotic Surgery in Gynecology.

Minimally invasive surgery (MIS) can be considered as the greatest surgical innovation over the past 30 years. It revolutionized surgical practice with well-proven advantages over traditional open surgery: reduced surgical trauma and incision-related complications, such as surgical-site infections, postoperative pain and hernia, reduced hospital stay, and improved cosmetic outcome. Nonetheless, proficiency in MIS can be technically challenging as conventional laparoscopy is associated with several limitations as the two-dimensional (2D) monitor reduction in-depth perception, camera instability, limited range of motion, and steep learning curves. The surgeon has a low force feedback, which allows simple gestures, respect for tissues, and more effective treatment of complications. Since the 1980s, several computer sciences and robotics projects have been set up to overcome the difficulties encountered with conventional laparoscopy, to augment the surgeon's skills, achieve accuracy and high precision during complex surgery, and facilitate widespread of MIS. Surgical instruments are guided by haptic interfaces that replicate and filter hand movements. Robotically assisted technology offers advantages that include improved three-dimensional stereoscopic vision, wristed instruments that improve dexterity, and tremor canceling software that improves surgical precision.
