[Induction of labor in women with previous caesarean delivery with balloon catheter: Is it worth it?] / Déclenchement par ballonnet en cas d'utérus cicatriciel et col défavorable : la tentative en vaut-elle la chandelle ?

OBJECTIF: Balloon catheters for labor induction at term after previous cesarean section is an alternative option to iterative cesarean section. The aim of this study was to analyze the maternal and neonatal outcomes of the trial of labor after cesarean (TOLAC) in women with unfavorable cervix and balloon catheter induction, 2 years after introduction of this process. METHODS: Unicentric observational study of women with term cephalic singleton, unfavorable cervix (simplified Bishop score<5) after TOLAC using double-balloon catheter. Were analyzed the mode of delivery and severe maternal (uterine rupture, post-partum hemorrhage, severe perineal tears) and neonatal (neonatal unit admission, APGAR<7 at 5minutes, pH<7.1) outcomes. Predictive factors for failed TOLAC were analyzed by using multivariate logistic regression. RESULTS: Between 2016-2017, 455 (75.4%) women had TOLAC, whose 59 (13%) women with balloon catheter. The overall vaginal delivery (VD) was 73.9%. After Balloon catheter, the VD rate was 50.8%, versus 79.1% after spontaneous labor, and 68.2% after alone oxytocin/artificial membrane rupture induction (P<0.05). Previous VD (aOR 0.176 CI-95% [0.048-0.651]) and prior sweeping membrane (aOR 0.161 CI-95% [0.034-0.761]) was protective for cesarean section after TOLAC. Severe maternal and neonatal morbidities were observed in 10 (17%) and 8 (13.6%) cases, respectively. CONCLUSION: Double-Balloon catheter is an option for unfavorable cervix and term induction after previous cesarean section. However, the TOLAC in women whose unfavorable cervix is not without maternal and neonatal risk, especially due to its failure.

Is episiotomy worthwile to prevent obstetric anal sphincter injury during operative vaginal delivery in nulliparous women?

OBJECTIVES: Episiotomy is a marker of Obstetric Anal Sphincter Injury (OASIS) condition, therefore, unmeasured factors could have biased the strength of the association between episiotomy and reduced OASIS during Operative Vaginal Delivery (OVD). The aim of this study was to compare the OASIS rate during OVD according to episiotomy practice. STUDY DESIGN: Retrospective cohort study of all nulliparous pregnant women attempting an OVD between 2014-2017. To avoid unmeasured bias, all maternal and delivery data were prospectively captured after the birth. The strong relationship between parity and episiotomy practice (indication bias) lead to analyze only nulliparous women. Association between mediolateral episiotomy and OASIS following OVD was performing by using multivariate logistic regression analysis including significant variable in univariate analysis and relevant factors known to be associated both with OASIS and/or OVD. RESULTS: Over the study period, 1709 (17.1%) women had an OVD, among them 40 (2.3%) had OASIS. In the 1342 (78.5%) nulliparous women, OASIS rate were 2% and 5.1% with and without episiotomy (p < 0.01). In multivariate analysis a lower incidence of OASIS with the use of episiotomy (OR 0.267 IC 0.132-0.541) were observed. The persistent occiput posterior position was associated with an increase risk of OASIS (OR 6.742 IC 2.376-19.124). Spatula/forceps, as compared to vacuum operative vaginal delivery increased the risk OASIS (OR 2.847 IC 1.311-7.168). Area under the curve of the model was 0.745. CONCLUSION: Episiotomy is a modifiable risk factors which can contribute to reduce the risk of OASIS in nulliparous women with operative vaginal delivery. This intervention should be included in a global management of the second stage of labor.

Induction du travail après une version par manœuvres externes pour siège réussie : un sur-risque de césarienne?

OBJECTIVE: To assess the effect of successful external cephalic version (ECV) on the risk of caesarean section (CS) during attempted vaginal delivery after induction of labour. METHODS: A unicentric matched retrospective observational case-control cohort study with exposed and unexposed groups. All pregnant women who had an induction of labour after a successful external cephalic version (sECV) between 1998 and 2016 were included. A total of 88 cases were compared with 176 controls (spontaneous cephalic presentation), matching for the year of delivery, parity, gestational age, indication and mode of induction of labour. The main outcome measure was the risk of caesarean. A univariate analysis and a multivariate logistic regression analysis were performed. RESULTS: The caesarean section rate was significantly higher after sECV (22% versus 13.1%; p = 0.039) especially for postdate pregnancy (55% versus 8.2%; p <0.05). For the univariate analysis, age (31 years and 4 months versus 24 years and 6 months; p <0.01) and maximal speed of oxytocin infusion (72 ml/h versus 68 ml/h; p = 0.04) were higher in the case group. The multivariate analysis showed that the risk of caesarean section was significantly increased after an sECV (aOR 1.946; 95% CI 1.017-3.772) and after the use of prostaglandins for ripening (aOR 1.951; 95% CI 1.097-3.468), and decreased for multipara (aOR 0.208; 95% CI 0.114-0.377). CONCLUSION: Women who have a successful ECV are at increased risk of caesarean section after subsequent induction of labour.

Bartholin gland abscess during pregnancy: Report on 40 patients.

OBJECTIVE(S): To study the clinical and bacterial characteristic of Bartholin gland abscesses during pregnancy and the obstetric and neonatal outcomes. STUDY DESIGN: Retrospective cohort study of all patients with surgical treatment of Bartholin gland abscesses between 2004 and 2015 in our university center. Clinical and bacterial characteristics between pregnant and non-pregnant women were compared. RESULTS: During the period study, 156 patients were included (40 pregnant and 116 non pregnant). The incidence of Bartholin gland abscesses during pregnancy was 0.13%. Eight (20%) abscesses occurred in the first, 18 (45%) in the second, 11 (47.5%) in the third trimester and 3 (7.5%) in the post-partum course. No severe perineal and neonatal infections occurred during pregnancy. One late miscarriage and one preterm delivery were observed. We found more multiparity in the pregnant woman group than in non-pregnant women (62.5% versus 45%, p<0.05). A history of Bartholin gland abscesses were also more frequent in pregnant women (55% versus 30.1%, p<0.05). First line antibiotic therapy was more frequent in non-pregnant women (20% versus 45%, p<0.05). The rate of positive culture did not differ between the two groups (70% versus 55.2%). Among negative pus cultures, no patient in the pregnant woman group had received a first line antibiotic therapy, in contrast with non-pregnant women (0% versus 25%, p<0.05). E. coli was the most common pathogen in the two groups (48.9% of positive cultures and 28.2% of the overall population). The distribution of bacterial taxa was not different between the two groups. CONCLUSION: Bacterial characteristics did not differ from non-pregnant women. Pregnancy could increase the occurrence of Bartholin gland abscesses in patients with previous surgical treatment of abscesses. When appropriate management is applied, maternal and neonatal outcomes are favorable, and severe infections are not to be expected.

[Cord accident after external cephalic version: Reality or mostly myth?] / Accident funiculaire après version par manœuvre externe : mythe ou réalité ?

OBJECTIVES: To study the occurrence of cords accident (nuchal cords, prolapse, and braces) after external cephalic version according to its failure or success. METHODS: Retrospective study between 1998-2015 comparing in the cord accident diagnosed at delivery (by midwife or doctors according to mode of delivery): Patients with attempt ECV: Group 1 cephalic presentation after successful ECV with trial of labor, and Group 2 failed ECV followed by elective cesarean or trial of labor. Patients with no attempt ECV Group 3 spontaneous cephalic presentation matching for delivery date, maternal age, parity, body mass index, and delivery history with group 1, Group 4 Breech presentation without attempt ECV with trial of labor. RESULTS: A total of 776 women with breech presentation were included (198 in group 1, 446 in group 2, 396 in group 3 and 118 in group 4). The prevalence of cord accident did not differ according to ECV attempt (17.08 % versus 18.9 %), to cephalic presentation (group 1: 24.7 % versus group 3: 25 %) and to breech presentation (group 2: 16.9 % versus group 4: 17.2 %). The trial of labor after failed ECV did not increase the risk of cord accident when compared with elective cesarean (17.4 % versus 16 %). A prolapse cord was only observed after trial of labor, i.e. in groups 1, 2 and 4 without difference (respectively 1, 0.8 and 1.7 %). In each group, the rate of cesarean was not different according to the presence of nuchal cord. CONCLUSION: Success or failed External cephalic version is not associated with an increased risk of cord accident.

Should fetal scalp blood sampling be performed in the case of meconium-stained amniotic fluid?

OBJECTIVE: To investigate the effect of using fetal scalp blood sampling on the risk of neonatal respiratory distress syndrome (NRDS) with meconium-stained amniotic fluid (MSAF). METHODS: Prospective data collection with regard to MSAF during labor for low-risk term cephalic singleton live birth from 2012 to 2014. Maternal, obstetric and neonatal data were compared according to the occurrence of respiratory distress syndrome (RDS group) or not (no RDS group). RESULTS: Of 515 newborns born through MSAF, 46 experienced RDS and from them 10 experienced meconium aspiration syndrome. No difference was observed according to maternal characteristic, abnormal fetal heart rate tracing pattern irrespective of its category and cesarean rate. Apgar at one minute was lower in the group RDS (7.6 versus 8.5, p < 0.05). The mean umbilical artery pH values did not differ between the two groups. Significant difference between newborns with and without RDS in terms of fetal scalp lactate sampling during the labor (71.1% versus 55.1%, p < 0.05), and neonatal care unit (NCU) admissions (22.8% versus 10.8%, p < 0.05). Secondary rather than primary meconium was associated with RDS when performing fetal scalp blood assessment (p < 0.05). A significant correlation between RDS, fetal scalp blood assessment and MSAF diagnosed during the first stage of labor (after spontaneous rupture of membranes or at amniotomy) was found. CONCLUSION: In case of MSAF, fetal scalp blood sampling did not reduce the risk of RDS.

[Cornual pregnancy: Management and subsequent fertility]. / Grossesse extra-utérine cornuale : prise en charge, fertilité ultérieure et devenir obstétrical.

OBJECTIVE: Cornual pregnancy is a rare entity, representing 2% of ectopic pregnancies. Its management is poorly codified and often guided by the clinical situation. The aim of our study was to describe the management of cornual pregnancies, subsequent fertility, and obstetric outcomes according to the management. METHODS: Observational retrospective unicentric study. Nineteen patients hospitalized for cornual pregnancy between 2006 and 2015 were included. The data was collected with medical records and a phone standardized questionnaire. Patients were managed according to hemodynamic status by either systemic or local methotrexate injection or surgical corneal resection. RESULTS: Among the 19 patients, 32% (6) were treated by systemic injection (one failure treated by surgical treatment) and 68% (13) underwent surgical treatment by cornual resection. The median HCG rate decrease was 33 days (16-62). Among the twelve patients with a desire for a new pregnancy, 7 (58%) became pregnant without assisted reproductive technology (2 following medical treatment and 5 following surgical resection). Histological analysis of uterine horn showed proximal fallopian tube lesions in 76.9% of case (chronic salpingitis, endosalpingiosis and adenomyosis). CONCLUSION: Cornual pregnancies are at high risk of hemorrhagic rupture. Ectopic recidive may occur. Fertility and obstetrical outcomes following cornual pregnancy are not affected whatever the initial treatment. Other studies are needed to aid clinical management according to HCG level and ultrasound features.

Pregnancy adverse outcomes related to pregravid body mass index and gestational weight gain, according to the presence or not of gestational diabetes mellitus: A retrospective observational study.

AIM: This study retrospectively evaluated the complications associated with prepregnancy overweight (OW) or obesity (OB) and gestational weight gain (GWG) in women with or without universally screened and treated gestational diabetes mellitus (GDM). METHODS: A total of 15,551 non-Asian women without pregravid diabetes or hypertension who delivered singleton babies (2002-2010) were classified according to GDM (13.5%), pregestational body mass index (BMI; normal range: 18.5-24.9kg/m(2)), OW (26.2%), OB (13.9%; BMI≥30kg/m(2)) and GWG (<7kg: 32%; 7-11.5kg: 37%; 11.6-16kg: 23%;>16kg: 8%). Main outcome measures were large/small for gestational age (LGA/SGA), caesarean section, preeclampsia, preterm delivery and shoulder dystocia. RESULTS: GDM was associated with more LGA babies [Odds Ratio (OR): 2.12, 95% confidence interval (CI): 1.85-2.43], caesarean section (OR: 1.49, 95% CI: 1.34-1.65) and preeclampsia (OR: 1.59, 95% CI: 1.21-2.09). OW/OB and GWG were associated with LGA infants whatever the GDM status, and with SGA babies only in women without GDM. LGA status was independently associated with GWG in women with GDM (11.6-16kg: OR: 1.74, 95% CI: 1.49-2.03 and>16kg OR: 3.42, 95% CI: 2.83-4.13 vs 7-11.5kg) and in women without GDM (OR: 2.14, 95% CI: 1.54-2.97 or OR: 2.65, 95% CI: 1.68-4.17, respectively), and with BMI only in women without GDM (OR: 1.12, 95% CI: 1.00-1.24, per 10kg/m(2)). SGA status was independently associated with OW (OR: 0.86, 95% CI: 0.77-0.98), OB (OR: 0.84, 95% CI: 0.72-0.98) and GWG<7kg (1.14, 95% CI: 1.01-1.29) only in women without GDM. CONCLUSION: In our European cohort and considering the triumvirate of GDM, BMI and GWG, GDM was the main contributor to caesarean section and preeclampsia. OW/OB and GWG contributed to LGA and SGA infants mainly in women without GDM.

[Disproportion between placenta weight and birth weight: Physiologic or pathologic]. / Disproportion fœto-placentaire à terme : physiologique ou pathologique.

OBJECTIVES: To study risk factors, maternal and neonatal outcome with a high placental weight to birth weight ratio (PW/BW). MATERIALS AND METHODS: Two groups of full term singleton pregnancies were created in this single centre retrospective population-based study (a high PW/BW above 0.25 and group control with normal PW/BW between 0.15 and 0.25). Maternal and neonatal outcomes were compared. RESULTS: Compared with the group with normal PW/BW ratios, the high PW/BW ratio group was associated with increased rates of pre-eclampsia (15.5% versus 1.7%, P<0.05) and small for gestational age (8% versus 0%, P<0.05). Neither maternal risk factors nor neonatal outcome difference were shown after adjusting confounding factors. CONCLUSION: High PW/BW with placentomegaly is associated with increased risk of pre-eclampsia at term underlying a mixture of condition in its pathogenesis.

[Obstetric and neonatal outcomes of adolescent pregnancies: a cohort study in a hospital in Seine-Saint-Denis France]. / Devenir obstétrical et néonatal des grossesses chez les adolescentes : cohorte de patientes en Seine-Saint-Denis.

OBJECTIVES: The aim of this study was to describe the characteristics, monitoring, obstetrical complications, childbirth and neonatal outcomes of pregnancies among minors in a cohort of adolescents from Seine-Saint-Denis (France). PATIENTS AND METHODS: This is a retrospective, cohort, comparative study, conducted from January 1, 1996 to July 31, 2011, made from the database of Jean-Verdier hospital in Seine-Saint-Denis. Three groups were established: patients aged less than 16 years old, patients aged over 16 years old and under 18 years old compared to a group consisting of older primiparas from 18 to 25 years old. The criteria considered were the characteristics of pregnancy, terms of delivery, neonatal outcome and conduct of post-partum. RESULTS: Minor patients were statistically more likely to be single, student, smoking and anemia compared to young adults. The obstetrical care was lower for minor compared to the control group with a number of consultations and ultrasounds lower (P < 0.001). Obstetrical complications were similar in the three groups outside of preterm labor. Adolescentes under 16 years old had a higher preterm delivery risk in multivariate analysis (RR = 0.33 CI 95% [0.12; 0.90] P = 0.03). Adolescents had fewer cesarean and instrumental deliveries (P < 0.05). DISCUSSION AND CONCLUSION: Teenage pregnancy remains an important managing issue for maternities, particularly from a social standpoint. On the medical side, one preterm delivery appears to be more common among these adolescents.

[Prognostic and predictive factors in multifocal breast carcinoma]. / Facteurs prédictifs et pronostiques des cancers du sein multifocaux.

OBJECTIVES: Multicentricity is not listed as a major prognostic parameter in invasive breast carcinoma, and is not by itself an indication of systemic adjuvant treatment. Furthermore, evaluating the size of these tumors is discussed. The aims of this study are to evaluate prognostic value of multicentricity, and to compare different way for measuring multicentric breast carcinomas. PATIENTS AND METHODS: Between 2001 and 2008, 1458 patients having breast invasive carcinoma were included in Tenon Hospital, Paris, France; 16% had a multicentric cancer. We have compared impact of multicentricity on lymph node (LN) involvement, and compared 3 ways for measuring these cancers. RESULTS: LN involvement was significantly associated with multicentricity. We found an over-risk of 20% for LN involvement in patients having multicentric cancer, whatever the size of the tumors. Considering the diameter of the largest focus is the best way for measuring these cancers. DISCUSSION AND CONCLUSION: We did not find a subgroup of patients at low risk of LN involvement when having a multicentric breast cancers. These results lead us to extend indications of adjuvant chemotherapies in all multicentric breast cancer. These results should be validated by randomized prospective studies.

[Clinicopathological and genomics predictors of response to neoadjuvant chemotherapy in breast cancer]. / Prédicteurs clinicopathologiques et génomiques de la réponse à la chimiothérapie néoadjuvante dans les cancers du sein.

Breast cancer is a frequent and heterogeneous disease. The choice of systemic treatments such as chemotherapy is based on predicting factors of response that did not much evolve. Preoperative chemotherapy provides an opportunity to directly assess tumor response to therapy. Predictors based on mathematical models could optimize those treatments. To go on this way, three different concepts have been developed to predict the preoperative chemotherapy complete response. Predictors based on clinical and pathological variables are specific of a tumor. They combine into mathematical models variables that have been previously identified as predicting the preoperative chemotherapy complete response. Predictors based on gene expression profile have been developed from groups of patients who received preoperative chemotherapy. They integrate multigene information to predict the tumor behaviour in front of several cytotoxic agents. Those predictors developed for each type of drug characterize the genetic chemoresistance of a tumor. In the same time, predictors of chemosensitivity developed from cell lines of diverse human cancer appeared. The authors established a genetic profile involved into chemoresistance and extrapolated the drug sensitivity for another type of cancer which was not represented, as breast cancer. All those predictors seem interesting but evolution of patients' characteristics and treatments induces a perpetual reassessment to optimize our predictive abilities.

[Surgical and functional results of rectosigmoidal resection for severe endometriosis]. / Résection rectosigmoïdienne pour endométriose profonde : résultats chirurgicaux et fonctionnels.

OBJECTIVES: Indications of colorectal resection for endometriosis are controversial because of the risk of major complications. This study aims to evaluate the value of different diagnostic tests in decision-making, and to evaluate the surgical results and complications, as well as long-term functional results after surgery. PATIENTS AND METHODS: In the set of a retrospective case series, 50 patients who have been admitted for a colorectal resection because of deep endometriosis were included. Most of them have had an MRI and an endorectal ultrasonography. Specific questionnaires have been proposed in order to evaluate symptoms, sexuality (BISF-W) and quality of life (EHP-30). RESULTS: For the diagnosis of rectal involvement, the sensitivity of MRI and endorectal ultrasonography were 55 and 100%, respectively. Forty-one colorectal amputations and nine partial colorectal resections have been done by 24 laparotomies, two laparoscopies and 24 laparoconversions. Major complications included six (12.5%) digestive fistulas, three (6%) anastomotic strictures, one ureterovaginal fistula and one ureteral stricture. Risk factors associated with digestive fistulas were the association of a vaginal opening (p=0.002) and an additional ileocaecal resection (p=0.007). The mean follow-up period was of 42 months. A significant improvement of dysmenorrhea (p<10(-4)), dyschesia (p<10(-4)), chronic pelvic pain (p<10(-4)), and of some digestive symptoms such as catamenial epreintes (p=0.002) and catamenial diarrheas (p=0.006), was noted. We noted postoperative 14 dysurias, six constipations and 12 rectal polykynesias. Four patients have had deep recurrent lesions. Twenty patients had a desire of pregnancy after the operation, 17 pregnancies were obtained (eight spontaneous and nine by ART) giving birth to 14 living children. Sexuality evaluation was below normal range. The quality of life was improved for most of the items. The global satisfaction was good (91%). DISCUSSION AND CONCLUSION: Colorectal resection for deep endometriosis improve significantly most of the pain symptoms, but the women should have detailed counselling about the risks of major complications and recurrence.
