Evaluating the safety of high-intensity focused ultrasound treatment for rectal endometriosis: results from a French prospective multicentre study including 60 patients.

STUDY QUESTION: Is increasing the intensity of high-intensity focused ultrasound (HIFU) by 30% in the treatment of rectal endometriosis a safe procedure? SUMMARY ANSWER: This study demonstrates the safety of a 30% increase in the intensity of HIFU in the treatment of rectal endometriosis, with no Clavien-Dindo Grade III complications overall, and namely no rectovaginal fistulae. WHAT IS KNOWN ALREADY: A feasibility study including 20 patients with rectal endometriosis demonstrated, with no severe complications, a significant improvement in digestive disorders, dysmenorrhoea, dyspareunia, and health status, although the volume of the endometriosis nodule did not appear to be reduced. STUDY DESIGN, SIZE, DURATION: A prospective multicentre cohort study was conducted between 2020 and 2022 with 60 patients with symptomatic rectal endometriosis. Following the failure of medical treatment, HIFU treatment was offered as an alternative to surgery. PARTICIPANTS/MATERIALS, SETTING, METHODS: As the main objective of this study was to examine safety, all adverse events observed during the 6 months of follow-up were analysed and graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) and Clavien-Dindo classifications. Secondary objectives included evaluating the evolution of symptoms using validated questionnaires: gynaecological and digestive pain symptoms with a visual analogue scale, health status with the Medical Outcomes Study 36-item Short Form (SF-36) questionnaire, average post-operative daily pain level, and analgesic medication required in the 10 days following treatment. MRI was also performed at Day 1 to detect early complications. Finally, we performed a blinded MRI review of the evolution of the nodule at 6 months post-treatment. MAIN RESULTS AND THE ROLE OF CHANCE: The procedure was performed under spinal anaesthesia for 30% of the patients. The median duration of treatment was 32 min. Fifty-five patients left the hospital on Day 1. MRI scans performed on Day 1 did not highlight any early-onset post-operative complication. Using the Clavien-Dindo classification, we listed 56.7% Grade I events, 3.4% Grade II events, and no events Grade III or higher. At 1, 3, and 6 months, all gynaecologic, digestive and general symptoms, as well as health status, had significantly improved. The evolution of the nodule was also significant (P < 0.001) with a 28% decrease in volume. LIMITATIONS, REASONS FOR CAUTION: The main objective was safety and not effectiveness. The study was not randomized and there was no control group. WIDER IMPLICATIONS OF THE FINDINGS: HIFU treatment for rectal endometriosis results in an improvement of symptoms with low morbidity; as such, for selected patients, it could be a valuable alternative to surgical approaches following the failure of medical treatment. STUDY FUNDING/COMPETING INTEREST(S): The study was funded by the company EDAP TMS. Professors Dubernard and Rousset are consultants for EDAP TMS. Dubernard received travel support from EDAP-TMS. Dr F. Chavrier received industrial grants from EDAP-TMS. He has developed a device for generating focused ultrasonic waves with reduced treatment time. This device has been patented by EDAP-TMS.

Assessment of operator performance during oocyte retrievals: residents' learning curve and continuous monitoring of senior physicians.

BACKGROUND: The learning curve cumulative summation test (LC CUSUM test) allows to define an individualized learning curve and determine the moment when clinical proficiency is attained. After acquisition of the skills, the cumulative summation test (CUSUM test) allows to monitor the maintenance of the required level over time. The LC CUSUM test has been frequently used in the field of Obstetrics and Gynecology (Ob/Gyn) for several procedures, but only once for OR. METHODS: We performed a retrospective study at Angers university hospital between May 2017 and September 2018. Seven Ob/Gyn residents and 5 senior physicians were included, and all OR performed during that time (n = 690) were analyzed. The performance index assessed was the oocyte retrieval rate (ORR), defined as the ratio of oocytes retrieved to follicles aspirated. We used the LC CUSUM test to analyze the learning curves of residents, and the CUSUM test to monitor the performance of senior physicians. An ORR ≥50% in 60% of retrievals was defined as the threshold for clinical proficiency. RESULTS: Six hundred seventy-four oocyte retrieval (OR) were included: 315 were performed by residents, 220 by senior physicians, and 139 by both residents and physicians (mixed retrievals). Four residents (57%) reached the threshold after aspirating 82, 67, 53 and 46 ovaries, respectively. The mean number of ovaries aspirated in order to reach clinical proficiency was 62, and the mean number of weeks needed was 21. The duration of the learning period varied between 26 and 80 days. Two senior physicians (40%) remained proficient across the duration of the study, while two physicians (40%) had one statistically "suboptimal" OR, and one physician (20%) had two suboptimal retrievals. CONCLUSION: There is a large variability in the duration of the learning period and the number of procedures needed for a resident to master OR. Senior physicians maintain an adequate performance.

COVID-19 infection in first trimester of pregnancy marked by a liver cytolysis in a woman previously treated by hydroxychloroquine for repeated implantation failure: a case report.

BACKGROUND: In December 2019, a new disease (COVID-19) caused by a novel coronavirus called SARS-CoV-2 emerged in China and spread to many other countries. There is only limited data about the clinical features of COVID-19 during pregnancy, especially in first trimester. CASE PRESENTATION: We report a COVID-19 infection in a 35 years-old patient in first trimester of pregnancy and its consequent medical care. At 7 weeks of pregnancy, the patient, who did not have any pregestational comorbidities, complained of intense nausea and asthenia. An important liver cytolysis was discovered with biological perturbations of transaminases levels. No respiratory symptoms were recorded. Classical viral aetiologies and drug-related toxicity were discarded. Because of the aggravation of the symptoms and the occurrence of the breathlessness, the patient was tested for the COVID-19 in a nasopharyngeal swab. The RTq-PCR assay indicated the presence of SARS-CoV-2 RNA. In the absence of severe symptoms, the patient was monitored at home according to the French government guidelines. After a few days, the symptoms resolved without any complications. The pregnancy is still ongoing without any visible sequelae on the foetus so far. CONCLUSIONS: This first case illustrated the difficulty of COVID-19 diagnosis in patients with isolated digestive symptoms in first trimester of pregnancy that could be confused with gravida hyperemesis. Monitoring of pregnancy after an episode of COVID-19 should be strengthened with bimonthly foetal growth ultrasounds and doppler assessments because of the risks for intrauterine growth restriction. Comprehensive data on larger numbers of first trimester gravid women with COVID-19 are required to better understanding the overall impact of SARS-CoV-2 on maternal and birth outcomes.

The mitochondrial DNA content of cumulus cells may help predict embryo implantation.

PURPOSE: The quantification of mtDNA in cumulus granulosa cells (CGCs) surrounding an oocyte has been positively linked with morphological embryonic quality. In the present study, we evaluated the link between the amount of mtDNA in CGCs surrounding an oocyte and the chances for the corresponding embryo of implanting and leading to an ongoing pregnancy. METHODS: This is an observational study, performed on 84 oocyte-cumulus-complexes (OCCs) having led to the replacement of an embryo in the maternal uterus, retrieved from 71 patients undergoing IVF with intracytoplasmic sperm. The OCCs were classified in two groups, one including 26 OCCs having led to an implanted embryo and the other including 58 OCCs having led to a non-implanted embryo. The average mtDNA content of CGCs was assessed by using a quantitative real-time PCR technique. RESULTS: Significantly higher mtDNA copy numbers in CGCs were associated with implanted embryos than with non-implanted embryos (mean 215 [sd 375] and 59 [sd 72], respectively; p < 104). Multivariate analysis, taking into account the women's age, the embryo quality, and the AMH level, suggests an independent relationship between the mtDNA content of CGCs and the potential of embryo implantation. CONCLUSION: During in vitro fertilization (IVF) procedures, the probability of the implantation of the embryo appears to be closely correlated to the mtDNA copy numbers in the CGCs. Our results highlight the interest of mtDNA quantification in GCGs as a biomarker of the potential of embryo implantation.

The mitochondrial DNA content of cumulus granulosa cells is linked to embryo quality.

STUDY QUESTION: Could the mitochondrial DNA (mtDNA) content of cumulus granulosa cells (CGCs) be related to oocyte competence? SUMMARY ANSWER: The quality of embryos obtained during IVF procedures appears to be linked to mtDNA copy numbers in the CGCs. WHAT IS KNOWN ALREADY: Oocyte quality is linked to oocyte mtDNA content in the human and other species, and the mtDNA copy number of the oocyte is related to that of the corresponding CGCs. Moreover, the quantification of CGC mtDNA has recently been proposed as a biomarker of embryo viability. STUDY DESIGN SIZE, DURATION: An observational study was performed on 452 oocyte-cumulus complexes retrieved from 62 patients undergoing ICSI at the ART Center of the University Hospital of Angers, France, from January to May 2015. PARTICIPANTS/MATERIALS, SETTING, METHODS: The average mtDNA content of CGCs was assessed by using a quantitative real-time PCR technique. The relationship between CGC mtDNA content and oocyte maturity and fertilizability, on one hand, and embryo quality, on the other, was investigated using univariate and multivariate generalized models with fixed and mixed effects. MAIN RESULTS AND THE ROLE OF CHANCE: No relationship was found between CGC mtDNA content and oocyte maturity or fertilizability. In contrast, there was a significant link between the content of mtDNA in CGCs surrounding an oocyte and the embryo quality, with significantly higher mtDNA copy numbers being associated with good quality embryos compared with fair or poor quality embryos [interquartile range, respectively, 738 (250-1228) and 342 (159-818); P = 0.006]. However, the indication provided by the quantification of CGC mtDNA concerning the eventuality of good embryo quality was seriously subject to patient effect (AUC = 0.806, 95%CI = 0.719-0.869). The quantity of CGC mtDNA was influenced by BMI and smoking. LARGE SCALE DATA: N/A. LIMITATIONS REASONS FOR CAUTION: The quantification of CGC mtDNA may indicate embryo quality. However, since it is affected by patient specificity, it should be used with caution. It remains to be seen whether this marker could directly predict the implantation capacity of the embryo, which is the main objective in IVF practice. WIDER IMPLICATIONS OF THE FINDINGS: Our study suggests that the quantification of CGC mtDNA may be a novel biomarker of embryo viability. However, patient specificity makes it impossible to establish a general threshold value, valid for all patients. Nevertheless, further studies are needed to determine whether the quantification of CGC mtDNA may, in combination with the morpho-kinetic method, offer an additional criterion for selecting the best embryo for transfer from a given cohort.

Deep sequencing shows that oocytes are not prone to accumulate mtDNA heteroplasmic mutations during ovarian ageing.

STUDY QUESTION: Does ovarian ageing increase the number of heteroplasmic mitochondrial DNA (mtDNA) point mutations in oocytes? SUMMARY ANSWER: Our results suggest that oocytes are not subject to the accumulation of mtDNA point mutations during ovarian ageing. WHAT IS KNOWN ALREADY: Ageing is associated with the alteration of mtDNA integrity in various tissues. Primary oocytes, present in the ovary since embryonic life, may accumulate mtDNA mutations during the process of ovarian ageing. STUDY DESIGN, SIZE, DURATION: This was an observational study of 53 immature oocyte-cumulus complexes retrieved from 35 women undergoing IVF at the University Hospital of Angers, France, from March 2013 to March 2014. The women were classified in two groups, one including 19 women showing signs of ovarian ageing objectified by a diminished ovarian reserve (DOR), and the other, including 16 women with a normal ovarian reserve (NOR), which served as a control group. PARTICIPANTS/MATERIALS, SETTING, METHODS: mtDNA was extracted from isolated oocytes, and from their corresponding cumulus cells (CCs) considered as a somatic cell compartment. The average mtDNA content of each sample was assessed by using a quantitative real-time PCR technique. Deep sequencing was performed using the Ion Torrent Proton for Next-Generation Sequencing. Signal processing and base calling were done by the embedded pre-processing pipeline and the variants were analyzed using an in-house workflow. The distribution of the different variants between DOR and NOR patients, on one hand, and oocyte and CCs, on the other, was analyzed with the generalized mixed linear model to take into account the cluster of cells belonging to a given mother. MAIN RESULTS AND THE ROLE OF CHANCE: There were no significant differences between the numbers of mtDNA variants between the DOR and the NOR patients, either in the oocytes (P = 0.867) or in the surrounding CCs (P = 0.154). There were also no differences in terms of variants with potential functional consequences. De-novo mtDNA variants were found in 28% of the oocytes and in 66% of the CCs with the mean number of variants being significantly different (respectively 0.321, SD = 0.547 and 1.075, SD = 1.158) (P < 0.0001). Variants with a potential functional consequence were also overrepresented in CCs compared with oocytes (P = 0.0019). LARGE SCALE DATA: N/A. LIMITATIONS, REASONS FOR CAUTION: Limitations may be due to the use of immature oocytes discarded during the assisted reproductive technology procedure, the small size of the sample, and the high-throughput sequencing technology that might not have detected heteroplasmy levels lower than 2%. WIDER IMPLICATIONS OF THE FINDINGS: The alteration of mtDNA integrity in oocytes during ovarian ageing is a recurring question to which our pilot study suggests a reassuring answer. STUDY FUNDING/COMPETING INTEREST(S): This work was supported by the University Hospital of Angers, the University of Angers, France, and the French national research centers, INSERM and the CNRS.

Targeted metabolomics reveals reduced levels of polyunsaturated choline plasmalogens and a smaller dimethylarginine/arginine ratio in the follicular fluid of patients with a diminished ovarian reserve.

STUDY QUESTION: Does the metabolomic profile of the follicular fluid (FF) of patients with a diminished ovarian reserve (DOR) differ from that of patients with a normal ovarian reserve (NOR)? SUMMARY ANSWER: The metabolomic signature of the FF reveals a significant decrease in polyunsaturated choline plasmalogens and methyl arginine transferase activity in DOR patients compared to NOR patients. WHAT IS KNOWN ALREADY: The composition of the FF reflects the exchanges between the oocyte and its microenvironment during its acquisition of gametic competence. Studies of the FF have allowed identification of biomarkers and metabolic pathways involved in various pathologies affecting oocyte quality, but no large metabolomic analysis in the context of ovarian ageing and DOR has been undertaken so far. STUDY DESIGN, SIZE, DURATION: This was an observational study of the FF retrieved from 57 women undergoing in vitro fertilization at the University Hospital of Angers, France, from November 2015 to September 2016. The women were classified in two groups: one including 28 DOR patients, and the other including 29 NOR patients, serving as controls. PARTICIPANTS/MATERIALS, SETTING, METHODS: Patients were enrolled in the morning of oocyte retrieval after ovarian stimulation. Once the oocytes were isolated for fertilization and culture, the FF was pooled and centrifuged for analysis. A targeted quantitative metabolomic analysis was performed using high-performance liquid chromatography coupled with tandem mass spectrometry, and the Biocrates Absolute IDQ p180 kit. The FF levels of 188 metabolites and several sums and ratios of metabolic significance were assessed by multivariate and univariate analyses. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 136 metabolites were accurately quantified and used for calculating 23 sums and ratios. Samples were randomly divided into training and validation sets. The training set, allowed the construction of multivariate statistical models with a projection-supervised method, i.e. orthogonal partial least squares discriminant analysis (OPLS-DA), applied to the full set of metabolites, or the penalized least absolute shrinkage and selection operator with logistic regression (LASSO-LR), applied to the ratios and sums of the metabolites. Both multivariate models showed good predictive performances when applied to the validation set. The final penalized model retained the three most significant variables, i.e. the total dimethylarginine-to-arginine ratio (Total DMA/Arginine), the sum of the polyunsaturated choline plasmalogens (PUFA ae), and the patient's age. The negative coefficients of Total DMA/Arginine and PUFA ae indicated that these FF variables had lower values in DOR patients than in NOR patients. LARGE SCALE DATA: N/A. LIMITATIONS REASONS FOR CAUTION: This study presents two limitations. First, with this targeted metabolomics analysis, we have explored only a limited portion of the FF metabolome. Second, although the signature found was highly significant, the mechanism underlying the dysfunction remains undetermined. WIDER IMPLICATIONS OF THE FINDINGS: The understanding of the mechanisms implied in ovarian ageing is essential for providing an adequate response to affected women desiring pregnancy. Our study proposes an incoming signature that may open new paths towards this goal. STUDY FUNDING/COMPETING INTEREST(S): This study was supported by the University Hospital of Angers, the University of Angers, and the French national research centers, INSERM and the CNRS.

Relationship between diminished ovarian reserve and mitochondrial biogenesis in cumulus cells.

STUDY QUESTION: What part do mitochondria play in cases of diminished ovarian reserve (DOR)? SUMMARY ANSWER: Mitochondrial biogenesis in cumulus cells may be linked with impaired oocyte competence in patients with DOR. WHAT IS KNOWN ALREADY: DOR, one of the causes of infertility even in young women, is characterized by the depletion of the ovarian pool associated with a decline in oocyte competence. Mitochondria, which play a role in oocyte quality, could be involved in the pathogenesis of DOR. The study of cumulus cells offers an interesting non-invasive approach for evaluating oocyte quality and the metabolic processes on which it depends. If mitochondrial dysfunction is involved in DOR, it is likely to have an impact on the functioning of cumulus cells. STUDY DESIGN, SIZE, DURATION: This is an observational study of 74 immature oocyte-cumulus complexes retrieved from 47 women undergoing in vitro fertilization with intracytoplasmic sperm injection at the University Hospital of Angers, France, from March 2013 to March 2014. The women were divided into two groups: one group included 26 women with DOR, and the other, which included 21 women with a normal ovarian reserve (NOR), served as a control group. PARTICIPANTS/MATERIALS, SETTINGS, METHODS: The oocyte mitochondrial content and the average mitochondrial content of the cumulus cells were assessed by mitochondrial (mt)DNA quantification using a quantitative real-time PCR technique. Microfluidic-based quantitative RT-PCR assays were used to quantify the expression of 13 genes involved in mitochondrial functions such as apoptosis and antioxidant activity or in mitochondrial biogenesis. We used orthogonal partial least-squares discriminant analysis (OPLS-DA) to distinguish between the DOR group and the NOR group of patients, and an OPLS model to predict the value of the oocyte mtDNA content that could be used as a critical marker of oocyte quality. MAIN RESULTS AND THE ROLE OF CHANCE: The OPLS-DA model showed a good predictive capability (Q2 = 0.543). Using the variable importance in projection (VIP) metric we found three mitochondrial variables distinguishing the DOR group from the NOR group of patients, i.e. the oocyte mtDNA content (VIP = 0.92), the cumulus cell mtDNA content (VIP = 0.95) and the expression in cumulus cells of peroxisome proliferator-activated receptor γ coactivator 1 alpha (PPARGC-1A) (VIP = 1.10), all of which were lower in the DOR group than in the NOR group of patients. The OPLS model was able to satisfactorily predict the oocyte mtDNA content in only the NOR group of patients (Q2 = 0.506). We found four new variables positively linked to the oocyte mitochondrial mass, i.e. the cumulus cell mtDNA content (VIP = 1.19), and the expression in cumulus cells of three factors of mitochondrial biogenesis: polymerase gamma (POLG) (VIP = 2.13), optic atrophy 1 (OPA1) (VIP = 1.89) and the transcription factor associated with mitochondria (TFAM) (VIP = 1.32). LIMITATIONS, REASONS OF CAUTION: This is a descriptive study. Because of ethical concerns in human clinical practice, this study has been performed only on immature oocytes and corresponding cumulus cells, which are usually discarded during in vitro fertilization procedures. WIDER IMPLICATIONS OF THE FINDINGS: Cumulus cells may govern mitochondrial biogenesis, creating an adequate oocyte mitochondrial pool to promote embryonic development. The alteration of this process in patients with DOR may account for the impairment of oocyte quality. This suggests that some mitochondrial characteristics of cumulus cells may serve as indicators of oocyte competence and that oocyte quality may be improved by products enhancing mitochondrial biogenesis.

Interest of human papillomavirus DNA quantification and genotyping in paired cervical and urine samples to detect cervical lesions.

BACKGROUND: Cervical cancer is caused by persistent infection with high-risk human papillomavirus (HR-HPV). Conventional human papillomavirus (HPV) testing requires cervical sampling. However, vaginal and urine self-sampling methods are more acceptable for patients and result in increased participation when they are available in screening programs. In this context, we have developed a non-invasive screening method via the detection of HPV DNA in urine samples. PURPOSE: To compare HPV viral loads and genotypes in paired cervical and urine samples, and to assess correlation between virological and cytological results in women seeking gynecological consultation. METHODS: Paired urine and cervical specimens were collected and analyzed from 230 of 245 women participating in the previously described prospective PapU study. HPV DNA detection and quantification were performed using a real-time PCR method with short fragment PCR primers. Genotyping was carried out using the INNO-LiPA HPV genotyping assay. RESULTS: The prevalence of HPV in the 230 paired urine and cervical smear samples was 42 and 49 %, respectively. Overall agreement for HPV positivity and negativity between the paired samples was 90 % (κ = 0.80). High HPV viral load in both cervical and urine samples was associated with cytological abnormalities. HPV-positive women were mostly infected with HR-HPV types. The agreement between high- and low-risk HPV (LR-HPV) detection in both samples was 97 % (κ = 0.95 for HR-HPV and κ = 0.97 for LR-HPV). CONCLUSIONS: High concordance rates for HPV-DNA quantification and high/low-risk HPV genotyping in paired urine/cervical samples suggest that urinary HPV DNA testing could be useful for cervical lesion screening.

Comparison of neonatal outcomes of cesarean sections performed under primary or secondary general anesthesia: a retrospective study.

BACKGROUND: The conversion of neuraxial anesthesia (NA) to general anesthesia (GA) during a cesarean section (CS) may be associated with a higher risk of neonatal morbidity by adding the undesirable effects of both these anesthesia techniques. We aimed to compare the neonatal morbidity of non-elective CS performed after conversion from NA to GA (secondary GA) vs. that after GA from the outset (primary GA). METHODS: We performed a monocentric retrospective study at the Angers University Hospital (France). All non-elective CSs performed under GA between January 2015 and December 2019 were included. The CSs were classified using a three-color coding system (green for non-urgent delivery, orange for urgent CS, and red for very urgent CS). The primary neonatal outcome was a composite of umbilical artery pH <7.10 or 5-min Apgar score <7. The crude and adjusted odds ratios (OR) for the risk of neonatal morbidity associated with secondary GA were estimated. RESULTS: We included 247 patients, of whom 101 (41.3%) had a secondary GA and 146 (58.7%) had primary GA. In the secondary GA group, 86.1% (87/101) had epidural anesthesia and 13.9% (14/101) had spinal anesthesia. Multivariate analysis showed no difference in neonatal morbidity between the two groups (adjusted odds ratio 1.18, 95% CI 0.56 to 2.51). CONCLUSIONS: Our study found insufficient evidence to identify a difference in neonatal outcomes between secondary compared with primary GA for CS, regardless of the level of emergency. However, our study is underpowered and additional studies are needed to confirm these data.

[Reconstructive surgery of the clitoris after sexual mutilation]. / Chirurgie plastique reconstructrice du clitoris après mutilations sexuelles.

Ritual sexual mutilations cause gynaecologic, urologic and obstetric complications. Their surgical treatments like clitoris reconstruction or desinfibulation have been well studied. We describe the Dr Pierre Foldes's (2004, 2006a, b) surgical technique of clitoris reconstruction after ritual excision. After scar resection, clitoris knee and corporeal bodies are liberated with meticulous nerve sparing. A new clitoridian glans is created by cuneiform plasty and then reimplanted in an anatomic situation. The aim of the technique is to restore a normal anatomy and to obtain a sensory and functional organ. We also describe the desinfibulation technique in this article.

[Postpartum urinary retention]. / Rétention vésicale du post-partum.

Postpartum urinary retention is an uncommon event that occurs in 0.7 to 0.9% of vaginal deliveries. An ignorance of this situation can lead to delayed diagnosis worsening the prognosis and to inadequate treatments. This complication is defined as the absence of spontaneous micturition within 6hours of vaginal delivery with a bladder volume above 400mL. The etiology depends on multiple factors. Because of physiological changes during pregnancy, the bladder is hypotonic with an increased post-void residual volume. The occurrence of a perineal neuropathy during delivery may cause a urinary retention. Risk factors are primiparity, prolonged labour, instrumental delivery and perineal lacerations. Treatment consists on clean intermittent catheterization and recovery occurs generally in 72hours. Persistent urinary retention is the principal short-term complication and should be treated by clean intermittent self-catheterization. Long-term consequences are poorly reported in the literature.

Positive impact of simulation training of residents on the patients' psychological experience following pregnancy loss.

OBJECTIVE: Our study aimed to assess the impact of a simulation training program for residents for the disclosure of diagnosis on the psychological experience of couples following a first trimester pregnancy loss (PL). METHODS: We performed an uncontrolled prospective single center, before-after study, at the gynecological emergency department of Angers University Hospital in France, between May 2014 and April 2015. We included all patients who had a confirmed diagnosis of first trimester PL. A self-administering questionnaire (SAQ) that included the short version of the perinatal grief scale (PGS) and questions about the couples' personal experience was sent by mail 8 weeks after the diagnosis. Patients were included before and after simulation training of the residents on the communication of the diagnosis of PL, and scores were compared between the two groups (before and after training). RESULTS: Overall 72 patients fulfilled the inclusion criteria and responded to the SAQ, 45 before and 27 after simulation training. Overall, simulation training significantly lowered the overall PGS (39.4±4.9 vs 57.3±5.6, p=0.03), significantly improved the attitude of the resident when announcing the diagnosis (more considerate (74.1 % vs 48.9 %, p=0.04) and available (59.3 % vs 28.9 %, p=0.01)), and significantly improved the quality of the information given (less incomprehensible (22.2 % vs 46.7 %, p=0.04). Finally, significantly fewer patients reported needing an additional consultation for further information following training (33.3 % vs 73.3 %, p=0.01). CONCLUSION: Simulation training of residents for the disclosure of early pregnancy loss significantly improves the couples' personal experience and decreases the psychological morbidity associated with the communication.

[Delivery of twins]. / Mode d'accouchement des grossesses gémellaires.

The assessment of optimal delivery for twin gestations is complex due to the relatively high frequency of obstetrical complications and to the heterogeneity of delivery management in these conditions. The extern validity of the Anglo-Saxon studies is limited in particular because delivery management of the second twin (approach of external cephalic version) differs from the French one (approach of internal version and/or total breech extraction) in cases of non-vertex second twin. Anglo-Saxon studies suggest that a planned vaginal delivery is associated to an increased risk of neonatal morbidity for second twin compared to first twin at term, in particular in cases of combined vaginal-cesarean birth. To reduce the interval twin-to-twin delivery interval and the number of combined vaginal-cesarean births, in our opinion, one must stop to perform external cephalic version and recommend a routinely active management for the second non-vertex twin delivery. With this active management, there is no evidence to support planned cesarean section for twins. Nevertheless, active management requires training as internal version might be difficult to perform, and therefore it is essential to pursue to teach junior obstetrician these obstetric maneuvers. There is limited role for trial of labor after cesarean delivery in twin gestation with a policy of active management.

[Linear insertion of atrioventricular valves (Livav): echocardiographic diagnosis, reliability and prevalence in the general population]. / Insertion linéaire des valves auriculoventriculaires (Ilvav): fiabilité du diagnostic échographique et prévalence dans une population sans trisomie 21.

OBJECTIVES: Assess the reliability of prenatal diagnosis of linear insertion of atrioventricular valves (Livav) by echocardiography as well as estimate Livav's prevalence in a population without Down syndrome. PATIENTS: One hundred and twenty-three fetuses of whom 113 were explored before and after birth and 631 consecutive out-patients explored in cardiopediatric unit. METHODS: Determination of the likehood ratio (LHR+ and LHR-) of Livav prenatal diagnosis. Evaluation of the consistency between pre- and postnatal diagnoses as well as between two observers after birth (Kappa index). Prevalence study according to the presence of Down syndrome, cardiac malformation or others abnormalities. RESULTS: LHR+ value was 6.17 and LHR- value was 0.30 for echographic Livav prenatal diagnosis. Consistency was low between pre- and postnatal diagnoses (Kappa = 0.57) and higher between two observers after birth (Kappa = 0.79). Livav prevalence was 2 to 5% in a population without Down syndrome but 15% when associated with a cardiac malformation. Seventy-eight percent Down syndromes had either Livav or AVSD. CONCLUSION: Livav echographic prenatal diagnosis is difficult, for it generates many false positives. Livav is not specific of Down syndrome and can be found relatively frequently in other subjects.

[Two observations of evisceration after caesarean section performed according the so-called Stark procedure]. / A propos de deux observations d'éviscération après césariennes réalisées selon la technique de Stark.

Two cases of evisceration after caesarean sections performed according the Misgav Ladach General Hospital procedure (Stark's procedure) are reported. In these cases, omentum was sutured between the edges of fascia recti, creating a weakness of the abdominal sheath. These cases claim about a strict procedure for fascia suture. Also, these cases question about the parietal peritoneal closure and the drawing of rectus muscles, which are vertical breaks; so, these sutures close transversal incision of the abdominal wall with cross sutures, which are very secure.

[Indications and prerequisites for operative vaginal delivery: when, how and where?]. / Indications et prérequis à la réalisation d'une extraction instrumentale : quand, comment et où ?

OBJECTIVE: To determine the indications and prerequisites for operative vaginal delivery. METHODS: Articles were searched using PubMed and Cochrane library. RESULTS: Indications for operative vaginal delivery are non-reassuring fetal status (NP4), no progress from 30minutes of adequate active pushing, maternal exhaustion (NP5), or medical indications to avoid Valsalva (NP5). Operative vaginal delivery (Thierry's spatulas, forceps, and vacuum delivery) before that cervix is fully dilated and fetal head is fully engaged is not recommended (NP4). Obstetricians have to know patient medical record and the fetal head position before performing operative vaginal delivery (NP5). The reliability of transvaginal examination to determine the fetal engagement and intrapartum fetal head position is 88% and 80% respectively (NP2). Transabdominal ultrasound assessment is recommended in cases of doubts about the fetal head position (NP5). Available data are not sufficient to fully contraindicated midpelvic operative delivery. Each case should be considered individually and depending on the skill of the obstetrician (NP5). Obstetricians should be aware that they may wrongly consider the fetus engaged in the midpelvis in 6% of cases, whereas it is not really engaged. Moreover, the presence of factors predictive of failed operative vaginal delivery must contraindicated midpelvic operative vaginal delivery and indicated a cesarean delivery (NP5). In general, midpelvic operative vaginal delivery is not recommended. Routine instrumental delivery in theatre and episiotomy for operative vaginal delivery are not recommended (NP3 and NP4, respectively). CONCLUSIONS: Recommendations for operative vaginal delivery should be respected to minimize both fetal and maternal trauma. Obstetricians should anticipate the complications that may occurred following operative vaginal delivery.

[Mini-sling versus transobturator sling: Efficiency and morbidity]. / Mini-bandelette sous-urétrale versus bandelette transobturatrice : efficacité et morbidité.

OBJECTIVE: To compare the effectiveness of an ALTIS® mini-sling and a conventionnal suburethral sling TVT-ABBREVO® for treatment of female stress urinary incontinence. METHODS: A single-center retrospective study included all female patients fitted with a conventional transobturator tape (TVT-ABBREVO®) or mini-sling (ALTIS®), during 2015, in Angers university hospital. The success rate was defined by no urine leakage during a cough test on clinical examination, improved quality of life defined by a PGI-I (Patient Global Impression of Improvement) score of 1 to 3, and no stress urinary incontinence on USP (Urinary Symptom Profile) questionnaire. Morbidity associated with slings and perioperative data were also recorded. RESULTS: Ninety-two patients were included (39 in the ALTIS group and 53 in the ABBREVO group). The average follow-up was 13.55 months. The success rate was not significantly different in ALTIS group for the negative cough test (89.7% vs 94.3% in ABBREVO group, P=0.45), for the absence of urinary leakage reported on the USP questionnaire (87.2% vs 90.6% in ABBREVO group, P=0.61), or for the improvement of the quality of life with a PGI-I score between 1 and 3 (82.1% vs 86.8% in ABBREVO group, P=0.53). On the other hand, more patients were fully satisfied, with a PGI-I quality of life score of 1, in ABBREVO group than in ALTIS group (67.9% compared with 46.2%, P=0.03). Immediate postoperative pain was significantly less intense in ALTIS group than in ABBREVO group (average VAS score of 0.5 comparated with 1.3, P=0.01), but this difference had disappeared one week after surgery. The rates of other complications were similar in both groups. CONCLUSION: The functional results of the ALTIS and TVT-ABBREVO® slings appear similar in the treatment of female stress urinary incontinence.
