Value of Biochemical Amniotic Fluid Analysis and Fetal Magnetic Resonance Imaging in the Prenatal Diagnosis of Congenital Microgastria.

INTRODUCTION: Congenital microgastria (CM) is a rare condition due to early interruption of stomach development between the 4th and 8th week of gestation, leading to a small midline tubular stomach. Prenatal diagnosis of CM is a challenge with important implications. This study explores the value of biochemical amniotic fluid (AF) analysis and fetal magnetic resonance imaging (MRI) for the prenatal diagnosis of CM in case of nonvisible stomach on fetal ultrasound. CASE PRESENTATION: Four cases of CM were retrospectively investigated in terms of fetal ultrasound, MRI findings, and biochemical AF analyses. The patients were referred to the Prenatal Diagnosis Unit of the Hôpital Femme Mère Enfant (Lyon, France) at a mean age of 21 weeks of gestation for absent or small fetal stomach on ultrasound with a suspected diagnosis of esophageal atresia (EA). Ultrasound examination confirmed that the stomach was absent in two of the four fetuses and small in the other two. This feature was associated with a congenital heart defect in two cases and a terminal transverse limb defect in one case. Standard genetic workup (array-CGH) results were normal. Biochemical AF analysis, including the EA index, was not suggestive of EA. Fetal MRI showed a small midline tubular stomach, associated with a dilated esophagus, highly suggestive of CM. CONCLUSION: If the fetal stomach is absent on ultrasound, CM should be considered if the AF volume is normal, especially during the third trimester, and if the EA index is not suggestive of gastrointestinal obstruction. In these cases, the diagnosis can be confirmed by fetal MRI, through observation of a small midline tubular stomach associated with a dilated esophagus.

Minimum evidence-based care in intrauterine growth-restricted fetuses and neonatal prognosis.

BACKGROUND: Introduction: There is clear evidence that fetuses with intrauterine growth restriction (IUGR) do not receive the minimum evidence-based care during their antenatal management. OBJECTIVE: Considering that optimal management of IUGR may reduce neonatal morbi-mortality in IUGR, the objective of the present study was to evaluate the impact of antenatal management of IUGR according to the recommendations of the French college of gynecologists and obstetricians (CNGOF) on the neonatal prognosis of IUGR fetuses. STUDY DESIGN: From a historical cohort of 31,052 children, born at the Femme Mère Enfant hospital (Lyon, France) between January 1, 2011 and December 31, 2017, we selected the population of IUGR fetuses. The minimum evidence-based care (MEC) in the antenatal management of fetuses with IUGR was defined according to the CNGOF recommendations and neonatal prognosis of early and late IUGR fetuses were assessed based on the whether or not they received MEC. The neonatal prognosis was defined according to a composite criterion that included neonatal morbidity and mortality. RESULTS: A total of 1020 fetuses with IUGR were studied. The application of MEC showed an improvement in the neonatal prognosis of early-onset IUGR (p = 0.003), and an improvement in the neonatal prognosis of IUGR born before 32 weeks (p = 0.030). Multivariate analysis confirmed the results showing an increase in neonatal morbi-mortality in early-onset IUGR in the absence of MEC with OR 1.79 (95% CI 1.01-3.19). CONCLUSION: Diagnosed IUGR with MEC had a better neonatal prognosis when born before 32 weeks. Regardless of the birth term, MEC improved the neonatal prognosis of fetuses with early IUGR. Improvement in the rate of MEC during antenatal management has a significant impact on neonatal prognosis.

Fetal and perinatal outcome associated with small cerebellar diameter based on second- or third-trimester ultrasonography.

OBJECTIVE: To examine the outcome of pregnancy with fetal transverse cerebellar diameter (TCD) below the fifth percentile based on routine second- or third-trimester ultrasonography. METHODS: We retrospectively analyzed the outcomes of 12 344 women according to TCD Z scores based on systematic second- or third-trimester ultrasound examination between 2007 and 2015. Information on major malformations, chromosomal anomalies, intrauterine or neonatal demise, and other abnormal findings were collected. RESULTS: In total, 408 fetuses with small prenatal TCD underwent clinical investigation; 160 major malformations were noted, consisting mainly of neurological or cardiac anomalies (39,2%%). Chromosomal anomalies were reported in 39 (9.5%) and intrauterine or neonatal demise in 41 cases (10%). Major malformations and chromosomal anomalies were found in 46.4% and 10% of fetuses with extremely small TCD (Z score < -2.5), respectively, 31.3% and 12.7% of fetuses with small TCD (Z score between -2.0 and -1.645), and 39.6 % and 7.7% of fetuses with subnormal TCD (Z score between -2.0 and -1.645). Intrauterine or neonatal demise was noted in 22%, 8.8%, and 4.8% of fetuses with extremely small, small, and subnormal TCD, respectively (P < .05). Among intrauterine growth-restricted fetuses, fetal demise or neonatal adverse outcome was reported in 75%, 81.8%, and 18.5%, respectively. Of all the fetuses, 2.2% were lost to follow-up. CONCLUSION: A small cerebellar diameter below the fifth percentile is a relevant marker to detect associated anomalies during routine ultrasound examination in the second or third trimester. This is related to a high rate of fetal malformations, chromosomal anomalies, and genetic disorders, regardless of the severity of the cerebellar small size. Small TCD seems to be a prognostic factor for fetal growth restriction. Therefore, when facing a TCD below the fifth percentile, patients should be referred for further sonography and fetal karyotyping.

Risk Factors of Inadequate Colposcopy After Large Loop Excision of the Transformation Zone: A Prospective Cohort Study.

OBJECTIVE: The aim of the study was to identify the risk factors of post-large loop excision of the transformation zone (LLETZ) inadequate colposcopy. MATERIALS AND METHODS: From December 2013 to July 2014, a total of 157 patients who had a LLETZ performed for the treatment of high-grade intraepithelial lesion with fully visible cervical squamocolumnar junction were included. All procedures were performed using semicircular loops. The use of colposcopy made during each procedure was systematically documented. Dimensions and volume of LLETZ specimens were measured at the time of procedure, before formaldehyde fixation. All participants were invited for a follow-up colposcopy 3 to 6 months after LLETZ. Primary end point was the diagnosis of post-LLETZ inadequate colposcopy, defined by a not fully visible cervical squamocolumnar junction and/or cervical stenosis. RESULTS: Colposcopies were performed in a mean (SD) delay of 136 (88) days and were inadequate in 22 (14%) cases. Factors found to significantly increase the probability of post-LLETZ inadequate colposcopy were a history of previous excisional cervical therapy [adjusted odds ratio (aOR) = 4.29, 95% CI = 1.12-16.37, p = .033] and the thickness of the specimen (aOR = 3.12, 95% CI = 1.02-9.60, p = .047). The use of colposcopy for the guidance of LLETZ was statistically associated with a decrease in the risk of post-LLETZ inadequate colposcopy (aOR = 0.19, 95% CI = 0.04-0.80, p = .024) as the achievement of negative endocervical margins (aOR = 0.26, 95% CI = 0.08-0.86, p = .027). CONCLUSIONS: Although the risk of post-LLETZ inadequate colposcopy is increased in patients with history of excisional therapy and with the thickness of the excised specimen, it could be reduced with the use of colposcopic guidance and the achievement of negative endocervical margins.

The Accuracy of Large Loop Excision of the Transformation Zone Specimen Dimensions in Determining Volume: A Multicentric Prospective Observational Study.

OBJECTIVE: The aim of the study was to determine which mathematical formula of specimen dimensions is the most accurate method of determining volume of the excised specimen at loop excision of the transformation zone. MATERIALS AND METHODS: A multicenter prospective observational study was conducted. A total of 258 patients who had a loop excision of the transformation zone performed as treatment of cervical intraepithelial neoplasia 2-3 were included. The dimensions and the volume of the specimen were measured at the time of the procedure, before formaldehyde fixation. The volume was measured by immersing the specimen in a graduated cylinder using Archimedes fluid displacement technique. The measured volume was compared with the calculated volume using different volume formulas, that is, a cone, a cylinder, a parallelepiped, and a hemiellipsoid. The main outcome measure was the relationship between calculated volume (using the dimensions of thickness, length, and circumference) and the measured volume of the specimen. RESULTS: The mean (SD) thickness, length, and circumference of specimens were 8.8 mm (3.8), 12.7 mm (5.9), and 45.7 mm (16.8), respectively. The mean (SD) measured volume was 2.53 (1.49) mL. Using the formula for the volume of a cone, a cylinder, a parallelepiped and a hemiellipsoid, estimated volumes were 1.03 mL (1.22), 3.10 mL (3.65), 6.20 mL (7.31), and 2.07 mL (2.44), respectively. The highest intraclass correlation coefficient between measured and calculated volume was observed when using the formula for the volume of a hemiellipsoid specimen (0.47, 95% CI = 0.36-0.56). CONCLUSIONS: The hemiellipsoid formula is the most accurate determinant of the excised volume. Other formulas do not allow for an accurate estimation of the excised volume.

Benefits of Direct Colposcopic Vision for Optimal LLETZ Procedure: A Prospective Multicenter Study.

OBJECTIVE: The aim of the study was to assess whether direct colposcopic vision (DCV) of the cervix during large loop excision of the transformation zone (LLETZ) is associated with a decrease in the volume and dimensions of specimens or affects margin status at histology. MATERIALS AND METHODS: A prospective multicenter observational study of 216 women who underwent LLETZ for grades 2 and 3 cervical intraepithelial neoplasia was conducted. The volume and dimensions (circumference, length, and thickness) of the surgical specimens were measured before fixation. Data were compared according to the use of colposcopy during LLETZ. The following 3 groups were considered: LLETZ performed without colposcopy (n = 91), LLETZ performed immediately after colposcopy (n = 51), and LLETZ performed under DCV (n = 74). RESULTS: Patient characteristics were comparable with regard to age, parity, history of excision, indication of the procedure, and the size of the cervix. We found a significant decrease in all dimensions of the specimens obtained under DCV (p < .001). Margin status was not affected. After adjusting for confounders, the mean volumes were significantly lower in the DCV group (adjusted mean difference = -0.66 mL; 95% CI = -1.17 to -0.14). The probability that negative margins would be achieved together with the attainment of a volume less than 5 mL and a thickness less than 10 mm was the highest in the DCV group (adjusted OR = 2.80; 95% CI = 1.13 to 6.90). CONCLUSIONS: Direct colposcopic vision is associated with a significant decrease in the volume and in all dimensions of LLETZ specimens with no compromise in the margin status.

Early detection of perinatal depression in couples: a single-center prospective study.

OBJECTIVE: This prospective study aimed to assess couples' psychological status during the perinatal period to identify those at risk for postpartum depression. METHODS: Conducted at Lyon University Hospital from March to July 2022, the study enrolled pregnant women without progressive psychiatric disorders or obstetric risk factors, and their partners. Participants completed the Edinburgh Postnatal Depression Scale (EPDS) at three points: during the 9th month of pregnancy, immediate postpartum, and 6-8 weeks after delivery. A score ≥10 on the EPDS indicated depression risk. A score ≥10 on the EPDS indicate depression risk. The primary endpoint was EPDS scores throughout the perinatal period. RESULTS: Ninety-five couples participated; 96% of patients and 68% of partners completed pre-delivery questionnaires, 81% and 71% during maternity stay, and 64% and 46% postpartum, respectively. Overall, 15% of patients and 1% of partners had EPDS scores >10 in the postpartum period. Psychiatric history and emergency cesarean sections were associated with higher immediate postpartum EPDS scores in patients [Beta 3.7 points, 95% CI 0.91; 6.4 and Beta 5.2 points, 2.2; 8.1, respectively]. Episiotomy was associated with higher EPDS scores in partners. No significant association between the different factors studied and the EPDS score was found at 6-8 weeks postpartum in patients nor their partners. CONCLUSIONS: While specific risk factors for persistent perinatal depression in couples were not identified, a notable proportion of patients exhibited high EPDS scores. Screening all couples during prepartum and postpartum periods is crucial, regardless of identified risk factors.

Combined first trimester screening for trisomy 21: Assessment of excess risk in case of free ß-human chorionic gonadotrophin between 5 and 10 multiples of the median.

OBJECTIVE: The first trimester combined risk of trisomy 21 is obtained by multiplying the risk related to maternal age by the likelihood ratios of nuchal translucency, free beta-human chorionic gonadotrophin (ß-hCG) and placenta associated plasma protein-A. Beyond five multiples of the median (MoM) of ß-hCG, the risk of trisomy 21 is truncated. The objective of the present study was to evaluate the evolution of the first trimester combined risk of trisomy 21 in individuals with first-trimester free-ß-hCG levels between 5 and 10 MoM. METHODS: We conducted a non-interventional cohort study from a 6-year database of combined first-trimester trisomy 21 screening of all individuals who underwent the screening in a French specialized medical analysis center. We included all pregnant individuals who had a serum-free ß-hCG between 5 and 10 MoM. Patients for whom the status of the fetus, with or without trisomy 21, was not identified by the outcome of the pregnancy or by a karyotype result were excluded from the study. The discriminatory capacity of free-ß-hCG above 5 MoM was studied by a receiver operating characteristic curve. We used an orthogonal polynomial regression to represent the evolution of likelihood ratios according to free-ß-hCG in MoM. RESULTS: Among 413 216 combined first-trimester screens of trisomy 21, 2239 (0.5%) screens met the inclusion criteria. In the selected population, 801 (35.8%) were excluded from the study because of missing fetal or neonatal status, and 46 (3.2%) fetuses out of 1438 included were diagnosed with trisomy 21. For free ß-hCG values between 5 and 10 MoM, the area under the curve is 0.56 (0.46-0.65). The scatterplot of the likelihood ratio of ß-hCG showed an increasing parabolic pattern: the likelihood of trisomy 21 increases with the free-ß-hCG threshold. CONCLUSION: To override the truncated risk of trisomy 21 in case of free ß-hCG values between 5 and 10 MoM, the study has allowed us to estimate the adjusted risk of trisomy 21, enabling health professionals to offer appropriate prenatal counseling.

Fibrinogen for the prediction of severe maternal complications in placental abruption with fetal death after 24 weeks of gestation.

OBJECTIVE: To assess the correlation between standard laboratory indicators at admission and severe maternal complications due to placental abruption (PA) with intrauterine fetal death (IUFD) after 24 weeks. METHODS: Retrospective study in three French tertiary referral hospitals. Correlation of laboratory indicators at admission (platelet count, prothrombin, activated partial thromboplastin time, fibrinogen) and severe maternal complications (massive transfusion, multiple organ failure, hysterectomy, or maternal deaths) in patients with PA and IUFD. RESULTS: Over 12 years, we identified 27/344 (7.8%) pregnant women presenting PA with IUFD. No patient had coagulopathy at admission. Fifteen individuals (55.5%) underwent delivery by cesarean section before or during labor. Fifteen individuals (55.5%) presented severe complications, and 17/27 (63%) lost more than 1 L of blood during delivery. Fibrinogen level was shown to be the laboratory indicator most correlated with severe complications (r = -0.52, P = 0.01). The receiver operating characteristic curve of fibrinogen less than 1.9 g/L in the prediction of severe complications (area under the curve = 0.80, 95% confidence interval [CI] 0.54-0.97) showed both a sensitivity and specificity of 83% (95% CI 54%-96%). CONCLUSIONS: In cases of IUFD with PA, fibrinogen levels at admission had a prognostic value for the prediction of severe maternal complications.

SARS-CoV-2 vaccine uptake and reasons for hesitancy among Canadian pregnant people: a prospective cohort study.

BACKGROUND: Several vaccines against SARS-CoV-2 have been developed and approved at an unparalleled speed. Given that SARS-CoV-2 vaccines are recommended to pregnant people, our aim was to quantify vaccination uptake, and describe vaccination hesitancy and behavioural attitudes surrounding SARS-CoV-2 vaccination in pregnancy in Canada. METHODS: The CONCEPTION study is an ongoing international study started in June 2020, evaluating the impact of the COVID-19 pandemic on the health of pregnant people and their children. For this study, pregnant people recruited from Apr. 20, 2021, to Feb. 8, 2022, and residing in Canada were invited to complete a Web-based survey. In addition to all CONCEPTION variables, data on vaccine uptake as well as personal knowledge of COVID-19 severity in pregnancy and of SARS-CoV-2 vaccine safety and efficacy were collected. Marginal risk differences and adjusted odds ratios (ORs) were calculated to assess determinants of SARS-CoV-2 vaccination during pregnancy. RESULTS: From Apr. 20, 2021, to Feb. 8, 2022, 603 pregnant people were recruited and gave consent, of which 83.7% (n = 505) were vaccinated and 16.3% (n = 98) were not vaccinated against SARS-CoV-2. Uptake of the influenza vaccine in 2020/21 was a significant predictor of being vaccinated against SARS-CoV-2 or intention to be vaccinated (marginal risk difference 3.2%, 95% confidence interval [CI] 3.0% to 3.3%, adjusted OR 4.43, 95% CI 2.32 to 9.25), and being employed (marginal risk difference 11.2%, 95% CI 10.6% to 11.9%, adjusted OR 2.17, 95% CI 1.03 to 4.35) increased the likelihood of being vaccinated against SARS-CoV-2. Self-assessed knowledge of COVID-19 severity and vaccine efficacy was not associated with vaccine uptake. INTERPRETATION: Among the Canadian pregnant people who responded to this study, vaccine uptake against SARS-CoV-2 was high. However, our results underscore the importance of improving knowledge transfer about the efficacy of SARS-CoV-2 vaccines in pregnancy to guide vaccination efforts.

Psychological impact on healthcare workers in obstetrics and gynecology in France in 18 French University Hospitals during the first Covid-19 lockdown: a prospective observational study.

PURPOSE: To assess the level of stress and anxiety in healthcare workers in the departments of obstetrics and gynecology in France during and after the first Covid-19 lockdown. METHODS: Two web-based cross-sectional surveys using several validated questionnaires (the HAD scale, the PSS-10 questionnaire and the Short Form 12 Questionnaire [SF-12]) were proposed to all staff of obstetrics and gynecologic departments in 18 French university hospitals. RESULTS: A total of 1565 respondents answered the first questionnaire and 1109 completed the second survey. Respondents reported greater levels of stress and impaired mental quality of life during the lockdown, followed by a significant improvement after the end of lockdown (respectively p < .0001 and p = .01). Anxiety was significantly higher among the older participants during the lockdown (p = .008). The potential putative factors related to impaired mental health status were personal protective equipment (PPE) deficit (<.0001), the fear of contracting the virus from the workplace and transmitting to their families (<.0001) and concerns about information given by media and hospitals (<.0001). CONCLUSIONS: Understanding the heavy mental repercussions of the Covid-19 pandemic on healthcare workers could lead to the identification of high-risk in medical and non-medical staff and the implementation of targeted psychological monitoring program.

Conservative surgical treatment of post-partum hemorrhage: Should we reconsider compression penetrating sutures?

OBJECTIVES: Evaluate the prevalence of uterine synechia after total uterine ligation (TUL) in comparison to TUL associated with compression-penetrating-sutures (CPS) in the conservative surgical management of severe postpartum hemorrhage (PPH). METHODS: Prospective observational study of pregnant women that underwent conservative surgical management for PPH in a single French tertiary referral center. We compared the risk of uterine synechia with TUL, in comparison to performing TUL in addition to CPS. The synechia rate was calculated after uterine cavity assessment by 3D hysterosonography. Hysterectomies, women with placenta accreta spectrum and patients that received additional embolization treatment were excluded. RESULTS: Over 6 years, 36 pregnant women underwent surgical treatment for PPH in 21,944 deliveries (1.64 per 1000). The median blood loss was 2700 [1570-3000] milliliters. Twenty-eight (77.7%) women underwent TUL, 8/36 (22.2%) underwent TUL in addition to CPS. Thirty-four (94,4%) cavity assessments were performed 2-to-6 months after delivery, since one woman of each group was lost to follow-up. When TUL was performed in addition to CPS, the prevalence of synechia was 42.9% (n = 3/7), versus 3.7% (n = 1/27) in TUL (p = 0.021; RR = 16.88, 95%CI [1.1-1051]). Synechia was absent in 30/34 (88.2%) women. CONCLUSION: The prevalence of synechia was very low after TUL unlike CPS. Further studies should evaluate TUL in the conservative surgical management of PPH, to confirm the lower prevalence of synechiae in TUL and evaluate its impact on fertility.

Fetal growth restriction: underdiagnosed condition with non-optimal screening.

BACKGROUND: Fetal Growth restriction (FGR) is the pathological failure of a fetus to reach its biologically determined growth potential. Detection of FGR fetuses is a universally agreed key objective of antenatal care. Antenatal detection of FGR has undeniable benefits, juggling between intensive fetal surveillance and optimized timing of delivery; it reduces adverse perinatal outcomes by up to four-fold. However, FGR is still widely underdiagnosed. We aimed to identify the prevalence of FGR diagnosis in our wards and study the impact of the 2013 published French guidelines on the detection rate of FGR. The secondary objective aimed to highlight the factors of suboptimal screening in the population of non-diagnosed FGR fetuses and emphasize the screening method that led to antenatal diagnosis of FGR. MATERIALS AND METHODS: We conducted a retrospective study at a single tertiary maternity center in Lyon-France, the Femme Mère Enfant Hospital, including the exhaustive population of FGR born after 24 + 0 weeks of gestation from 1 January 2011 to 31 December 2017. FGR was defined combining the neonatal and antenatal consensus-based definitions for early and late FGR in absence of congenital anomalies, excluding small for gestational age fetuses. For all FGR fetuses, we compared the antenatal detection rate of FGR during 2011-2013 to 2015-2017, since the French guidelines were published in December 2013. When FGR fetuses underwent an antenatal diagnosis of FGR, we retrospectively collected the characteristics that led to the diagnosis. When fetuses were not diagnosed as FGR, we retrospectively reviewed the implementation of the recommended screening method, enabling to evaluate whether screening was optimal or not. Statistical analysis was performed in July 2018, and statistical significance was regarded as a p-value <.05. RESULTS: Over the seven-year period, and among 31,052 newborns, 1020 (3.3%) infants were identified as FGR and met the inclusion criteria. The detection rate of FGR was similar before and after publication of the French Guidelines related to FGR in 2013. Indeed, 50.8% (201/395) FGR were diagnosed between 2011 and 2013 versus 52.6% (245/465) between 2015 and 2017 (p = .59). In the population of non-diagnosed FGR infants, screening was suboptimal in 80%. Symphysis-fundal height (SFH) was not measured in 10.7%, with no difference before and after 2014 (7.3 versus 11.8% p = .11). Ultrasound examination for fetal biometry had not been prescribed in spite of abnormal SFH in 47.7% of undiagnosed FGR infants. Diagnosis has been missed in 11.5% of infants because of misinterpretation of the estimated fetal weight's centile. CONCLUSION: FGR is widely underdiagnosed. However, the limited performances can partially be explained by the regular misuse of screening method in clinical practice. Despite the systematic third trimester ultrasound screening, the detection rate of FGR was similar to the one reported in the medical literature. The timing of routine third trimester ultrasound in low-risk women may be rethought.

Fourth degree perineal tears: Surgical repair technique in 10 steps.

Obstetrical anal sphincter injury (OASIS) may lead to significant comorbidities, including anal incontinence, rectovaginal fistula, and pain. A correct repair is required to avoid improper healing, as a persistent defect in the external anal sphincter after delivery can increase the risk of complications and worsening of symptoms following subsequent vaginal deliveries. Herein is described the surgical repair technique for a fourth degree perineal tear. Regarding resident education, there are challenges associated with the proper training in OASIS repair. The procedure is illustrated by an instructive video article that standardizes the essential steps to make the technique ergonomic and easy to perform with step-by-step explanations.

Standardized healthcare pathway in intrauterine growth restriction and minimum evidence-based care.

INTRODUCTION: Fetal growth restricted fetuses are less likely to receive evidence-based care; a previous work demonstrated an improvement in neonatal prognosis when fetuses with intrauterine growth restriction (IUGR) received minimum evidence based-care. OBJECTIVE: The objective of the study was to evaluate the impact of a standardized healthcare pathway on the implementation of the recommended clinical practice in the antenatal management of IUGR fetuses, in comparison to a traditional pathway. The quality of the implementation of practice has been defined whether or not minimum evidence-based care (MEC), defined according to the recommendations of the French college of gynecologists and obstetricians (CNGOF), has been implemented. STUDY DESIGN: From a historical cohort of 31,052 children, born at the Femme Mère Enfant Hospital (Lyon, France) between January 1st, 2011 and December 31st, 2017, we selected the population of IUGR fetuses. We compared the rate of MEC between the IUGR fetuses followed-up in the traditional healthcare pathway versus the IUGR fetuses followed-up in a standardized healthcare pathway between 2015 and 2017. RESULTS: A total of 245 IUGR were tracked between 2015 and 2017. Over this period, 120 fetuses were followed within the traditional pathway and 125 within the IUGR pathway. The standardized pathway resulted in a higher rate of MEC (86,4%) when compared to IUGR fetuses followed-up in the traditional pathway (27,5% (OR* 20 (95 % CI 10.0-39.7). Among early-onset IUGR: 31 % received MEC in the traditional pathway versus 83 % in the standardized pathway (p<0.001). Among late-onset IUGR: 22 % received MEC in the traditional pathway versus 92 % in the standardized pathway (p<0.001). The provided care in the standardized pathway resulted in an increase of complete antenatal corticosteroid therapy (92,8 %) when compared to the traditional pathway (50.0 %; p<0.001) and a reduction of the rate of caesarean sections before labor for non-reassuring fetal heart rate (15 %) when compared to the traditional pathway (41.3 % p=0.007). CONCLUSION: The standardized pathway improves the implementation of the local recommendations in the management of early- and late-onset IUGR. This study is the first to suggest a standardized care pathway in prenatal medicine. A medico-economic study could estimate the health care savings that such a pathway would provide by allowing a medical management in accordance with the recommendations.

Vesicules or placental lakes in ultrasonography, determining the correct etiology.

The prenatal examination of the placenta is often an afterthought to that of the fetus in ultrasonography. Not giving the placenta its due may however result in potentially serious placental pathologies remaining undiscovered, notably in the presence of anechoic zones. These latter have earned numerous names, including "placental lakes", "placental venous lakes", "placental lacunae" or "placental caverns" among others, but they have received little attention in the literature. We thus feel that it is essential to review the various pathologies that placental lakes may signal, since any one of them may greatly affect patient management. The difficulty resides in the diversity of these pathologies, sometimes oncological, other times fetal, and in the potential need for multidisciplinary surgery. Some of these causes of placental lakes may result in maternal or fetal complications and/or necessitate increased and casespecific surveillance. The diagnosis and treatment of such cases requires close collaboration between sonographers, obstetricians, geneticists and pathologists. The work we present here focuses on the different etiologies to consider in the presence of a lacunar placenta and the necessary diagnostic measures. Our objective is to propose a diagnostic flowchart to aid clinicians in this dense differential diagnosis.

Technics to put on and remove personal protective equipment before surgical or obstetrical procedure in suspected or infected COVID-19 patients (with video).

Coronavirus pandemic is widely changing our professional daily practice and preventive measures must be taken and taught. Before any planned gynaecological or obstetric surgery, specific technics to put on and safely remove personal protective equipment should be implemented in order to avoid any contamination for both patients and healthcare workers.

[Aspirin and preeclampsia]. / Aspirine et prééclampsie.

Indications for aspirin during pregnancy are a matter of debate and there is a recent trend to an extended prescription and an overuse of aspirin in pregnancy. Aspirin is efficient in secondary prevention of preeclampsia essentially in patients with a personal history of preeclampsia. The effect of aspirin on platelet aggregation and on the TXA2/PGI2 balance is dose-dependent. The optimum dosage, from 75mg/day to 150mg/day, needs to be determined. Fetal safety data at 150mg/day are still limited. The efficacy of aspirin seems to be subject to a chronobiological effect. It is recommended to prescribe an evening or bedtime intake. Aspirin, in primary prevention of preeclampsia, given to high-risk patients identified in the first trimester by screening tests, seems to reduce the occurrence of early-onset preeclampsia. Nevertheless, there are insufficient data for the implementation of such screening procedures in practice.

Prenatal imaging features suggestive of liver gestational allo immune disease.

We report prenatal imaging features of four cases of neonatal hemochromatosis due to an alloimmune disease. All cases exhibited intra uterine growth restriction (IUGR) without arguments for a vascular etiology, associated with oligohydramnios. Placental hydrops was present in 75% of cases. Splenomegaly was identified in one case. Other causes of NH have been ruled out during diagnostic workup including karyotype, detection of IGFBP-1 to evaluate a premature rupture of membranes, maternal serologic tests. MRI was performed in two cases and showed an atrophic liver associated with a low signal intensity on T2-sequence in one case. Prenatal NH was suspected in this later case and the fetus was successfully treated with two IVIG (intravenous immunoglobulins) perfusions performed during pregnancy followed by exchange transfusion and IVIG after birth. The child is doing well with normal liver function tests after 17 months of follow up. Our aim was to highlight the importance of suggesting NH-GALD when facing IUGR with oligohydramnios, ascites, placental hydrops, splenomegaly on prenatal ultrasound with negative work up for placental vascular pathologies and infectious fetopathies. MRI might be of a good help, showing an atrophic liver but enhancing iron overload in hepatic and extrahepatic tissue is helpful but not constant.

Early pelvic floor muscle training after obstetrical anal sphincter injuries for the reduction of anal incontinence.

OBJECTIVES: Between 0.5 and 5% of vaginal deliveries involve obstetrical anal sphincter injuries (OASIS). Thirty to forty percent of patients with OASIS will suffer from anal incontinence in the subacute postpartum period. The aim of the present study was to assess the effectiveness of early pelvic floor muscle training (PFMT) combined with standard rehabilitation on anal incontinence after vaginal deliveries complicated by OASIS. STUDY DESIGN: The present work was a retrospective quantitative study performed in a tertiary-level maternity hospital. Women with 3rd or 4th degree obstetric tears were included. Women who gave birth between January 1st, 2011 and December 31st, 2012 underwent standard pelvic-perineal rehabilitation within 6-8 weeks postpartum. Women who gave birth between January 1st, 2013 and July 1st, 2014 had early rehabilitation (within 30 days after delivery) followed by the same standard rehabilitation received by the other group. Rehabilitation was performed by physiotherapists specialized in perineology. No electrostimulation was done in early rehabilitation. An in-house-validated modification of the Jorge and Wexner questionnaire was sent by mail to the patients to assess symptoms. The main judgment criterion was anal incontinence to gas, loose stools and/or solid stool. RESULTS: Two hundred and thirty patients were diagnosed with OASIS. Nineteen women (8.3%) were lost to follow-up. The intention-to-treat analysis included 211 patients, 109 of whom underwent standard rehabilitation and 102 early rehabilitation plus standard rehabilitation. The two groups were comparable in terms of parity, birth weight, assisted delivery, epidural anesthesia and rates of mediolateral episiotomy. Multivariate analyses adjusted for type of perineal lesion were performed. Early rehabilitation significantly reduced gas leakage: OR 0.51 [0.29-0.90] (p=0.02), liquid stool leakage: OR 0.22 [0.08-0.58] (p=0.02) and urinary stress incontinence: OR 0.43 [0.24-0.77] (p=0.004). CONCLUSIONS: We recommend early (during the first month postpartum) PFMT after vaginal deliveries associated with OASIS. Rehabilitation should be carried out by a physiotherapist specialized in perineology in order to prevent medium-term functional consequences. A longer follow-up may be necessary to confirm the stability of results.
