Resume Introduction L’IRM mammaire est l’examen de reference pour le depistage chez les patientes a haut risque genetique de cancer du sein. Sa sensibilite et sa specificite, pouvant etre limitees par le rehaussement physiologique glandulaire, il est actuellement recommande d’effectuer l’IRM de depistage dans la deuxieme semaine du cycle menstruel, ce qui peut compliquer programmation. L’objectif de notre etude etait d’evaluer l’interpretation (ou la performance) de l’IRM realisee hors de la periode souhaitee. Methodes Nous avons analyse les IRM consecutives realisees a l’Hopital Tenon chez les patientes a haut risque genetique, sans antecedent de cancer du sein, entre 2006 et 2016. Nous avons analyse le taux de rehaussement genant l’interpretation (RG) – c’est-a-dire les rehaussements de types III et IV –, le taux d’explorations supplementaires realisees (IRM et biopsie) et la survenue d’evenement d’intervalle dans 2 groupes selon les conditions de realisation de l’examen : programmation adequate (j7–j14) et programmation inadequate (en dehors de la periode recommandee). Resultats Au total, 126 IRM ont ete etudiees, realisees chez 62 patientes porteuses d’une mutation genetique predisposant au cancer du sein (BRCA 1 ou 2 : 91 %, autre : 9 %), d’âge moyen 34,5 ans, en programmation adequate (n = 84), et inadequate (n = 42). Le taux de RG etait comparable dans les 2 groupes (respectivement 31 % et 35,7 %, p = 1), ainsi que la realisation d’explorations complementaires (respectivement 31 % et 45 %, p = 0,11). Conclusion Nos resultats suggerent que la programmation de l’IRM de depistage pourrait etre simplifiee dans la population specifique des patientes indemnes a haut risque genetique de cancer du sein.

BACKGROUND Testicular sperm extraction (TESE) is an essential therapeutic tool for the male infertility management. However, it is an invasive procedure and is successful in up to 50%. Until now, no model, based on the clinical and laboratory parameters, is sufficiently powerful to accurately predict the success of sperm retrieval in TESE. OBJECTIVE The objective of this study is to compare a wide range of predictive models under similar conditions for TESE outcomes in patients with non-obstructive azoospermia (NOA) to identify the correct mathematical approach to apply thereto, as well as the most appropriate study size and the relevance of input biomarkers. METHODS Two-hundred and one patients who underwent TESE at Tenon Hospital (AP-HP, Sorbonne University, Paris) distributed in a retrospective training cohort of 175 patients (2012 to April 2021) and a prospective testing cohort (May 2021 to December 2021) of 26 patients were analyzed. Eight machine learning (ML) models were evaluated (temporal validation) and compared. RESULTS The best model was the random forest (RF): (Area under curve) AUC = 89.6%, sensitivity = 100%, and specificity = 69,2%. Moreover, a study size of 120 patients seemed to be sufficient to properly exploit the preoperative data during the modeling process. Furthermore, inhibin B and a history of varicoceles exhibited the highest predictive capacity. CONCLUSIONS Using the appropriate approach, an ML algorithm can accurately predict successful sperm retrieval in men with NOA under-going TESE. However, it will be necessary to confirm and validate these results in a multicentric prospective study prior to practical use. The applicability of seminal plasma biomarkers, especially noncoding RNAs, as markers of residual spermatogenesis in NOA patients also requires further study.

La contraception d’urgence (CU) évolue depuis les années 1960, devenant de mieux en mieux tolérée par les femmes qui la prennent. Les contraceptions d’urgence hormonales ont ainsi utilisé des doses d’hormones de plus en plus faibles, avec des schémas d’utilisation simplifiés. Les œstrogènes ont finalement été abandonnés, conduisant à la mise en vente de ces contraceptions sans besoin d’une prescription. Le dispositif intra-utérin au cuivre, qui nécessite, quant à lui, le recours à un professionnel de santé, est moins accessible. Pourtant, il permet l’instauration d’une contraception au long cours. Malgré des progrès indéniables, la contraception d’urgence reste encore trop peu utilisée, faute d’une information efficace mais aussi de différents freins.

Objective We aimed to evaluate the impact of the sentinel lymph node (SLN) biopsy on adjuvant therapy, recurrence and survival in early endometrial cancer (EC). Study design We retrospectively included all patients who underwent SLN biopsy for EC between February 2007 and March 2018. Results Of the 249 EC patients included, the overall SLN detection rate was 91 %. SLNs were positive in 36 (14.4 %) cases. Nine of the 13 preoperative low-risk patients with positive SLNs were re-operated and 22 % presented positive non-SLNs. No second surgery was required for the 10 patients upstaged to intermediate risk after negative SLN biopsy. Nine of the 11 preoperative intermediate-risk patients with positive SLNs were re-operated and 33 % presented positive non-SLNs. Eleven of the 24 preoperative high-risk patients with negative SLNs were re-operated and 27 % presented positive non-SLNs. For the whole population, 3-year overall survival was 99 % (CI 95 % (97−1)) and 3-year recurrence-free survival (RFS) was 92 % (CI 95 % (0.87−0.95)). Conclusion Our study supports the feasibility of the SLN procedure for assessing risk recurrence in patients with early-stage EC. SLN biopsy should lead to major reductions in secondary staging and better adaptation of adjuvant therapy.

FERTILITY PRESERVATION BEFORE OVARIAN MALIGNANCY TREATMENT While most ovarian epithelial malignancies affect postmenopausal women, 12% occur in reproductive age patients. In addition, borderline ovarian tumors and rare non epithelial ovarian tumors are diagnosed in young patients as well. The prognosis of early-stage epithelial tumors, non-epithelial and frontier tumors is good. Increased knowledge in this specific field now allows the development of fertility preservation strategies. They include conservative surgery when applicable, associated with oocyte and / or ovarian tissue cryopreservation. Indications remain limited, and any decision must be validated by a multidisciplinary expert committee. The different strategies depend on specific tumoral or genetic context.PRÉSERVATION DE LA FERTILITÉ AVANT TRAITEMENT D’UN CANCER DE L’OVAIRE Le cancer épithélial de l’ovaire atteint en majorité les patientes ménopausées. Cependant, 12 % des patientes ont moins de 44 ans. Les tumeurs frontières de l’ovaire et les tumeurs rares non épithéliales sont diagnostiquées plus fréquemment chez les femmes en âge de procréer. Le pronostic des stades précoces et des tumeurs non épithéliales est favorable. Les avancées scientifiques permettent de développer des stratégies de préservation de la fertilité, qui reposent d’abord sur la possibilité d’une chirurgie conservatrice et sur la préservation de gamètes ou de tissus germinaux. Les indications restent néanmoins limitées, et toute décision doit être discutée en réunion de concertation pluridisciplinaire (RCP) de recours. Les différentes stratégies dépendent du contexte tumoral ou génétique.

Our objective was to evaluate surgical outcomes of robotic compared to conventional laparoscopy for colorectal surgery for endometriosis.We conducted a prospective cohort study comparing robotic to conventional laparoscopy for colorectal endometriosis during an 18-month period. We included 61 patients in the robotic group and 61 patients in the conventional laparoscopy group.Regardless of the colorectal procedure, no differences were found between the groups for complications, blood loss, re-hospitalisation, surgical revision. Robotic surgery was associated with a higher operating time (208 ± 90 min vs. 169 ± 81 min, p = 0.01) and a higher rate of healthy margins (91% vs. 76%; p = 0.01). For the patients undergoing discoid or segmental resections, robotic surgery was associated with a lower intraoperative complication rate (2% vs. 14%; p = 0.04) without difference in operating time or in postoperative complication rates, including voiding dysfunction.Our results suggest that the robotic route confer advantages for discoid and segmental resections.

Introduction : Up to 30% of couples may face secondary infertility. The impact of ectopic pregnancy, spontaneous abortion, pregnancy termination or live birth with caesarean section may impair further fertility in different ways. However, secondary infertility after physiological vaginal life childbirth has been little studied. The aim of this study was to describe the population and the fertility issues and analyze the predictive factors of success in in vitro fertilization in women presenting secondary infertility after a physiological vaginal childbirth. Material and methods : This single-centre retrospective study included women aged 18-43 years consulting between 2013 and 2020 for secondary infertility in a couple having already had previous vaginal life childbirth. Couples’ characteristics, management decision after the first consultation and IVF outcomes were analyzed. Results : Secondary infertility was found in 286 couples, out of whom 138 had a history of vaginal life childbirth. Population was characterized by an advanced female age and overweight. After the first consultation, IVF was performed in only 40% of couples. No predictive factor of live birth was found. Conclusion : Our study shows that in couples with secondary infertility after prior physiological delivery cigarette smoking is frequent in male partners, and ovarian reserve markers are altered. However, no statistically significant predictive factor of live birth after IVF treatment has been identified. Further large prospective studies are necessary.

Emergency contraception (EC) has evolved since the 1960's to enable a better tolerance. Lower hormone doses, simplified schemes, withdrawal of estrogens have led to a user friendly, over-the-counter available EC. The copper intra-uterine device, requiring health care professionals' intervention, is less accessible. However, it allows simultaneous initiation of a reliable long-term contraception. Unfortunately, EC is still underused and information reinforcement is needed to overcome reluctance to its use.La contraception d’urgence - Une longue histoire.La contraception d’urgence (CU) évolue depuis les années 1960, devenant de mieux en mieux tolérée par les femmes qui la prennent.

(1) Background: Ulipristal acetate (UPA) is a selective progesterone receptor modulator (SPRM) widely used for emergency contraception and mid- to long-term leiomyoma treatment. The aim of this study was to identify modifications of miRNA expression in superficial and basal layers of the human endometrium at the end of the UPA treatment for at least 3 months. (2) Methods: Microarray miRNA analysis of formalin-fixed, paraffin-embedded hysterectomy tissue samples was conducted, followed by an Ingenuity Pathway Analysis. Samples were divided into three groups: women having had 3 months of UPA treatment (n = 7), and two control groups of UPA-naïve women in the proliferative (n = 8) or secretory (n = 6) phase. (3) Results: The UPA modified the expression of 59 miRNAs involved in the processes of cell cycle, carcinogenesis, and inflammation. Their expression profiles were different in the basal and superficial layers. Most of the processes influenced by the UPA in the basal layer were connected to the cell cycle and immune regulation. (4) Conclusion: Specific changes were observed in both layers of the endometrium in the UPA group. However, the miRNA expression in the basal layer was not consistent with that in the superficial layer. Other large studies analysing the long-term impact of SPRM on endometrial miRNA expression are necessary.

Research question Does mild COVID-19 infection affect the ovarian reserve of women undergoing an assisted reproductive technology (ART) protocol? Design A prospective observational study was conducted between June and December 2020 at the ART unit of Tenon Hospital, Paris. Women managed at the unit for fertility issues by in-vitro fecundation, intracytoplasmic sperm injection (IVF/ICSI), fertility preservation, frozen embryo transfer or artificial insemination, and with an anti-Mullerian hormone (AMH) test carried out within 12 months preceding ART treatment, were included. All the women underwent a COVID rapid detection test (RDT) and AMH concentrations between those who tested positive (RDT positive) and those who tested negative (RDT negative). Results The study population consisted of 118 women, 11.9% (14/118) of whom were COVID RDT positive. None of the tested women presented with a history of severe COVID-19 infection. The difference between the initial AMH concentration and AMH concentration tested during ART treatment was not significantly different between the COVID RDT positive group and COVID RDT negative group (–1.33 ng/ml [–0.35 to –1.61) versus –0.59 ng/ml [–0.15 to –1.11], P = 0.22). Conclusion A history of mild COVID-19 infection does not seem to alter the ovarian reserve as evaluated by AMH concentrations. Although these results are reassuring, further studies are necessary to assess the effect of COVID-19 on pregnancy outcomes in women undergoing ART.

International audience; The molecular responses to hormonal stimuli in the endometrium are modulated at the transcriptional and post-transcriptional stages. Any imbalance in cellular and molecular endometrial homeostasis may lead to gynecological disorders. MicroRNAs (miRNAs) are involved in a wide variety of physiological mechanisms and their expression patterns in the endometrium are currently attracting a lot of interest. miRNA regulation could be hormone dependent. Conversely, miRNAs could regulate the action of sexual hormones. Modifications to miRNA expression in pathological situations could either be a cause or a result of the existing pathology. The complexity of miRNA actions and the diversity of signaling pathways controlled by numerous miRNAs require rigorous analysis and findings need to be interpreted with caution. Alteration of miRNA expression in women with endometriosis has been reported. Thus, a potential diagnostic test supported by a specific miRNA signature could contribute to early diagnosis and a change in the therapeutic paradigm. Similarly, specific miRNA profile signatures are expected for RIF and endometrial cancer, with direct implications for associated therapies for RIF and adjuvant therapies for endometrial cancer. Advances in targeted therapies based on the regulation of miRNA expression are under evaluation.

Villitis of unknown etiology (VUE) is characterized by lympho-histiocytic infiltrates, which are predominant within the villous stroma. VUE can be of low grade i.e. affecting less than 10 contiguous villi or high grade with either patchy or diffuse subgroups (the later concerning more than 30 % of distal villi). Several other placental lesions could be associated with VUE, in particular in diffuse subgroups, such as diffuse perivillous fibrin deposition and chronic intervillositis. One of the most characteristic features of VUE is the late onset of fetal growth restriction after 32 weeks of gestation, and earlier detection of villitis should first raise an infectious origin. High grade VUE has been associated with fetal growth restriction, prematurity, fetal deaths, recurrent pregnancy loss, central nervous system injury and is characterized by relatively high risk of recurrence (25-50 %). Prospective and well-designed studies are necessary to determine the real prevalence of these adverse pregnancy events associated with VUE. Data about the management of VUE are extremely scarce and thus no recommendation based on the literature review could be actually done.

Introduction Recurrent miscarriages are defined as three or more early miscarriages before 12 weeks of gestation. The aim of this study was to describe a cohort of women with unexplained recurrent miscarriages, evaluate several potential biomarkers of immune origin and describe the outcome of pregnancies under immunomodulatory therapies METHODS: Women having a history of at least 3 early miscarriages without any etiology were recruited from 3 university hospitals. Results Among 101 women with recurrent miscarriages, overall, 652 pregnancies have been included in the analysis. Women which experienced miscarriages were older (33.3 ± 5.4 versus 31.9 ± 6.7; p = 0.03), with history of more pregnancies (4 (2-6) versus 3.5 (1-5.75); p 0.0008), and less frequently the same partner (406 (74%) versus 79 (86%); p=0.01). There was no difference in the level and frequencies of biomarkers of immune origin (NK, lymphocyte, gammaglobulins and blood cytokine levels and endometrial uNK activation status), except the higher rates of positive antinuclear antibodies in women with live birth (12 (13%) versus 36 (7%); p=0.03). Among the 652 pregnancies, 215 (33%) have been treated and received either aspirin/low weighted molecular heparin (LMWH) and/or combined to different lines of immunomodulatory treatment. Patients with pregnancy under treatment had a significantly higher rate of cumulative live birth rate that those with untreated ones (43.0% vs 34.8%; p = 0.04). When compared to patients with untreated pregnancies, patients with steroids during the pregnancy had twice more chances to obtain live birth (OR 2.0, CI95% 1.1 - 3.7, p = 0.02). Conclusions Unexplained recurrent miscarriages could have improved obstetrical outcome under immunomodulatory therapies and in particular steroids.

STUDY QUESTIONCould the anogenital distance (AGD) as assessed by MRI (MRI-AGD) be a diagnostic tool for endometriosis?SUMMARY ANSWERA short MRI-AGD is a strong diagnostic marker of endometriosis.WHAT IS KNOWN ALREADYA short clinically assessed AGD (C-AGD) is associated with the presence of endometriosis.STUDY DESIGN, SIZE, DURATIONThis study is a re-analysis of previously published data from a case–control study.PARTICIPANTS/MATERIALS, SETTING, METHODSWomen undergoing pelvic surgery from January 2018 to June 2019 and who had a preoperative pelvic MRI were included. C-AGD was measured at the beginning of the surgery by a different operator who was unaware of the endometriosis status. MRI-AGD was measured retrospectively by a senior radiologist who was blinded to the final diagnosis. Two measurements were made: from the posterior wall of the clitoris to the anterior edge of the anal canal (MRI-AGD-AC), and from the posterior wall of the vagina to the anterior edge of the anal canal (MRI-AGD-AF).MAIN RESULTS AND THE ROLE OF CHANCEThe study compared MRI-AGD of 67 women with endometriosis to 31 without endometriosis (controls). Average MRI-AGD-AF measurements were 13.3 mm (±3.9) and 21.2 mm (±5.4) in the endometriosis and non-endometriosis groups, respectively (P LIMITATIONS, REASONS FOR CAUTIONThis was a retrospective analysis and no adolescents had been included.WIDER IMPLICATIONS OF THE FINDINGSThis study is consistent with previous works associating a short C-AGD with endometriosis and the absence of correlation with the disease phenotype. MRI-AGD is more accurate than C-AGD in this setting and could be evaluated in the MRI examination of patients with suspected endometriosis.STUDY FUNDING/COMPETING INTEREST(S)N/A.TRIAL REGISTRATION NUMBERThe protocol was approved by the ‘Groupe Nantais d’Ethique dans le Domaine de la Santé’ and registered under reference 02651077.

International audience; Pelvic and para-aortic lymphadenectomy are associated with increased risk of complications and are responsible for a significant proportion of morbidity and impaired quality of life following surgical management of pelvic malignancies. Sentinel lymph node (SLN) was developed as a trade-off between systematic and no lymphadenectomy to limit morbidity while conserving good oncological staging and outcomes. In this comprehensive review, we aimed to synthetize the anatomical basis of the SLN procedure in patients with pelvic malignancies from a surgical perspective. The reliability of the SLN procedure is based on the knowledge of the dissemination pathways for each type of tumors. The most recent understanding of the uterine lymphatic anatomy defined three consistent channels: an upper paracervical pathway (UPP) with draining medial external and/or obturator lymph nodes; a lower paracervical pathway (LPP) with draining internal iliac and/or presacral lymph nodes and the infundibulo-pelvic pathway (IPP) with a course along the fallopian tube and upper broad ligament via the infundibulo-pelvic ligament to its origin. In patients with endometrial cancer, most SLNs are located on the UPP pathway: obturator and external iliac whereas 80% of the SLNs in patients with cervical cancer are located in the external iliac, interiliac and obturator area. Surgical training is a key step toward improving detection rates and exhaustiveness of SLN research while reducing overall morbidity. This is all the more important that the indications for performing complete lymphadenectomy are becoming increasingly rare.

Appendiceal mucinous neoplasm (AMN) is defined as a distended, mucous-filled appendix. It is a rare condition seen in only 8% of cases of appendiceal tumors. Appendiceal mucocele associated with endometriosis is extremely rare with only 16 cases described in the literature to date. In view of the scarcity of the finding, few data are available on preoperative assessment of AMN in women with endometriosis. The goal of the present study was to describe the imaging features that could be suggestive of AMN in the context of endometriosis, as well as the specific management and outcomes.

Objective To describe strategy and results of fertility preservation (FP) in patients with malignant and borderline ovarian tumors. Methods Consecutive cohort study of 43 women with malignant or borderline ovarian tumors who underwent FP between February 2013 and July 2019. The study was conducted in national expert center in Tenon University Hospital, Sorbonne University: French ESGO-certified ovarian cancer center and pregnancy-associated cancer network (CALG). Main outcome measure was FP technique proposed by multidisciplinary committee, FP technique used, time after surgery, number of fragments, histology and follicle density (if ovarian tissue freezing), number of expected, retrieved and frozen oocytes (if ovarian stimulation). Results Pathological diagnosis was malignant epithelial ovarian tumor in five women (11.6%), rare malignant ovarian tumor in 14 (32.6%), borderline in 24 (55.8%), and mostly unilateral (79.1%) and stage I (76.7%). Mean age at diagnosis was 26.8 ± 6.9 years and mean tumor size 109.7 ± 61 mm. Before FP, mean AFC was 11.0 ± 6.1 and AMH levels were 2.7 ± 4.6 ng/mL. Six ovarian tissue-freezing procedures were performed (offered to 13). Twenty-four procedures of ovarian stimulation and oocyte freezing were performed after surgical treatment for 19 women (offered to 28) with a median interval of 188 days. The mean number of mature oocytes retrieved per stimulation was 12.4 ± 12.8. At least 10 mature oocytes were frozen for 52.6% of the women. No FP was offered to five women. Conclusion Oocyte and ovarian tissue cryopreservation should be offered to patients with malignant and borderline ovarian tumors. More data are needed to confirm ovarian stimulation and ovarian tissue grafting safety.

Recurrent implantation failure is defined as the absence of pregnancy after at least three transfers of good-quality embryos after in vitro fecundation/intracytoplasic sperm injection.The aim of this study was to describe a multicentre cohort of women with unexplained RIF, to analyse the factors associated with clinical pregnancy and to evaluate the immunomodulatory therapies efficacy.Women were consecutively recruited from university departments with unexplained RIF.Sixty-four women were enrolled with mean age 36 ± 3 years. The rates of clinical pregnancy in 64 women were compared in untreated and treated cycles and according to therapies used during the last prospectively followed embryo transfer. A clinical pregnancy after the transfer was noted in 56 % pregnancies on intralipids and in 50 % on prednisone, versus 5 % in untreated ones (p0.001). The 340 embryo transfers of these 64 women resulted in 68 clinical pregnancies and 18 live births. Clinical pregnancies were significantly more frequent in treated versus untreated embryo transfers (44 % vs 9 %; p0.001) with odds ratio at 8.13 (95 % CI 4.49-14.72, p0.0001). Cumulative pregnancy rates were higher for steroid-treated transfers than for untreated transfers when considering overall transfers before and after using steroids and also only those under steroids. Cumulative pregnancy rates were not different from steroid- and intralipid-treated embryo transfers CONCLUSIONS: In this multicentre study of women with unexplained RIF, use of immunomodulatory treatments before embryo transfer resulted in higher clinical pregnancy. Randomised, well-designed studies in well-defined population of RIF women are necessary to confirm our preliminary data.

International audience; Background: Endometriosis is a multifactorial pathology dependent on intrinsic and extrinsic factors, but the immune deregulation seems to play a pivotal role. In endometriosis-associated infertility this could raise the benefit of immunomodulatory strategies to improve the results of ART. In this review, we will describe (1) sera and peritoneal fluid cytokines and immune markers; (2) autoantibodies; (3) immunomodulatory treatments in endometriosis with infertility.Methods: The literature research was conducted in Medline, Embase and Cochrane Library with keywords: "endometriosis", "unexplained miscarriage", "implantation failure", "recurrent implantation failure » and « IVF-ICSI », « biomarkers of autoimmunity", "TNF-α", "TNF-α antagonists", "infliximab", "adalimumab", "etanercept", "immunomodulatory treatment", "steroids", "intralipids", "intravenous immunoglobulins", "G-CSF", "pentoxyfylline".Results: Several studies analyzed the levels of pro-inflammatory cytokines in sera and peritoneal fluid of endometriosis-associated infertility, in particular TNF-α. Various autoantibodies have been found in peritoneal fluid and sera of infertile endometriosis women even in the absence of clinically defined autoimmune disease, as antinuclear, anti-SSA and antiphospholipid autoantibodies. In few uncontrolled studies, steroids and TNF-α antagonists could increase the pregnancy rates in endometriosis-associated infertility, but well-designed trials are lacking.Conclusion: Endometriosis is characterized by increased levels of cytokines and autoantibodies. This suggests the role of inflammation and immune cell deregulation in infertility associated to endometriosis. The strategies of immunomodulation to regulate these immune deregulations are poorly studied and well-designed studies are necessary.

Results from studies reporting the optimal stimulation duration of IVF-ICSI cycles are inconsistent. The aim of this study was to determine whether, in the presence of early ovulation-triggering criteria, prolonged ovarian stimulation modified the chances of a live birth. This cross-sectional study included 312 women presenting triggering criteria beginning from D8 of ovarian stimulation. Among the 312 women included in the study, 135 were triggered for ovulation before D9 (D ≤ nine group) and 177 after D9 (D > nine group). The issues of fresh +/− frozen embryo transfers were taken into consideration. Cumulative clinical pregnancy and live-birth rates after fresh +/− frozen embryo transfers were similar in both groups (37% versus 46.9%, p = 0.10 and 19.3% versus 28.2%, p = 0.09, respectively). No patient characteristics were found to be predictive of a live birth depending on the day of ovulation trigger. Postponing of ovulation trigger did not impact pregnancy or live-birth rates in early responders. A patient’s clinical characteristics should not influence the decision process of ovulation trigger day in early responders. Further prospective studies should be conducted to support these findings.

Introduction The effect of coronavirus disease (COVID-19) on pregnancy outcome in women with sickle cell disease (SCD) is unknown. Objectives To analyze the severity of the SARS-CoV-2 infection in pregnant women with SCD and its impact on pregnancy. Methods This retrospective cohort study included SCD pregnant women tested positive for COVID-19 between March 2020 – February 2021. The primary endpoint was the severity of the COVID-19 infection. Secondary endpoints were pregnancy complications and fetal outcomes. Results During the study period among 82 pregnant women with SCD, 8 have presented symptoms suggestive of COVID-19 and were tested positive. A common mild clinical presentation was observed in 6 women (75%), one woman was asymptomatic and one required oxygen. The latter was admitted to the Intensive Care Unit and a cesarean section was performed in the context of an ongoing vaso-occlusive crisis and acute chest syndrome together with incidental preeclampsia. Labor was induced in another patient who developed a vaso-occlusive crisis after COVID-19 remission. Fetal outcomes were good with an average Apgar score of 10 and normal umbilical blood pH at birth. Two newborns were small-for-gestational-age as expected on the ultrasound follow-up before occurrence of COVID-19. Conclusion COVID-19 infection in our population of pregnant women with SCD had typical presentation and rarely triggered a sickle cell crisis or other complications. Fetal outcomes were good and did not seem to be directly influenced by the SARS-CoV-2 virus. Further studies are required to confirm these observations as compared to the population of women with SCD without COVID-19 infection.

Artificial Intelligence (AI), a concept which dates back to the 1950s, is increasingly being developed by many medical specialties, especially those based on imaging or surgery. While the cognitive component of AI is far superior to that of human intelligence, it lacks consciousness, feelings, intuition and adaptation to unexpected situations. Furthermore, fundamental questions arise with regard to data security, the impact on healthcare professions, and the distribution of roles between physicians and AI especially concerning consent to medical care and liability in the event of a therapeutic accident.

Intramyometrial ectopic pregnancies are rare, and various management modalities have been described. We report a patient with intramyometrial pregnancy who was successfully treated by in situ injection of methotrexate (MTX) after the failure of 2 intramuscular injections of MTX. We emphasize the difficult management of intramyometrial pregnancy and show that in situ MTX injection may be indicated for this particular type of ectopic pregnancy.

Selective progesterone receptor modulators (PRMs) are steroid progesterone receptor ligands able to induce agonistic or antagonistic activities. Mifepristone, the class leader, was primarily used for pregnancy termination from the 1980s. Emergency contraception with extended activity was the second major development 30 years later, using mifepristone in some countries and ulipristal acetate worldwide. Finally, more recently Ulipristal acetate was released for the treatment of myoma-related uterine bleeding. In addition to a very rapid cessation of bleeding, PRMs allow decrease in myoma volume. Estradiol secretion is not blunted by PRMs. This offers new alternatives for myoma treatment, especially in women close to menopause.

We aimed to compare the proportion of peripheral blood natural killer (NK) cells (CD3–CD56+) and T-cell large granular lymphocytes (CD8+CD57+) during preconception in a homogenous group of women with unexplained well-defined recurrent miscarriage (RM) and repeated implantation failure (RIF) vs healthy controls in relation to pregnancy outcomes. This case–control study followed by a literature review and meta-analysis was conducted in three university hospitals. Patients and controls were consecutively recruited from December 2015 to October 2017. In total, 115 women were included in the study: 54 with RM, 41 with RIF and 20 healthy controls with ≥ 2 term births. Percentages of CD3–CD56+ and CD8+CD57+ cells and sub-populations of CD3–CD56+ cells did not differ between cases and controls. The results for women with subsequent miscarriage did not differ from those with live births. The meta-analysis of the literature showed higher NK-cell proportions in RM [mean difference 3.47 (95% CI 2.94–4.00); p

International audience; RESEARCH QUESTION: What are the effects of ulipristal acetate (UPA) on the expression of endometrial proliferation and maturation markers?DESIGN: A total of 45 endometrium-containing blocks of hysterectomy samples from non-menopausal women with a diagnosis of moderate to severe symptoms of uterine fibroids: 14 women operated on at the end of a 3-month course of UPA; four women who had discontinued UPA treatment 1-12 months before surgery; 27 control unexposed samples (14 in the proliferative and 13 in the secretory phase). Immunohistochemical staining of Ki67, vascular endothelial growth factor-receptor 2 (VEGFR2), oestradiol receptor, progesterone receptor, interleukin-15 (IL-15), indoleamin-2,3-dioxygenase (IDO) and C-C motif chemokine ligand-2 (CCL2) markers were analysed in both endometrial compartments and layers.RESULTS: Under UPA, oestradiol receptor and progesterone receptor expression is similar to the proliferative phase in both layers, although with a decrease in cell proliferation. IL-15, IDO and CCL2 expressions are similar to the proliferative phase, suggesting a progesterone-antagonist effect of UPA. VEGFR2 staining suggests a trend to a mixed agonist-antagonist effect. No significant difference is observed in the post-UPA proliferative phase group compared with the control group in both layers of the endometrium.CONCLUSION: The effect of 3-month UPA treatment is mostly progesterone receptor antagonist-like. After treatment is discontinued, there are no signs of any long-term effects of this molecule on endometrial proliferation and maturation. Therefore, UPA may be administered to women willing to conceive in the short term without consequences for further implantation.

Nevus sebaceous is a complex hamartoma most commonly found on the scalp, face, and neck and is often present at birth, although some may be diagnosed later in infancy. We report the first prenatal diagnosis of isolated nevus sebaceous that presented at 19 weeks' gestation as a large and exophytic tumor of the scalp. This case emphasizes the crucial role of ultrasound examination performed with high-frequency probes, which revealed associated diffuse lesions of the face. Identification of such a facial involvement could have a dramatic prognostic impact. © 2013 John Wiley & Sons, Ltd.

Key Clinical Message Nonvisualization of the gallbladder during the second trimester of pregnancy should prompt concern for biliary atresia. A normal‐sized gallbladder with irregular and crenelated wall associated with a cyst of the extrahepatic tract should raise concern for cystic biliary atresia.

Nevus sebaceous is a complex hamartoma most commonly found on the scalp, face, and neck and is often present at birth, although some may be diagnosed later in infancy. We report the first prenatal diagnosis of isolated nevus sebaceous that presented at 19 weeks' gestation as a large and exophytic tumor of the scalp. This case emphasizes the crucial role of ultrasound examination performed with high-frequency probes, which revealed associated diffuse lesions of the face. Identification of such a facial involvement could have a dramatic prognostic impact.
