Maternal Nutritional Deficiencies and Small-for-Gestational-Age Neonates at Birth of Women Who Have Undergone Bariatric Surgery.

The aim is to compare the prevalence of maternal deficiencies in micronutrients, the obstetrical and neonatal complications after bariatric surgery according to surgical techniques, the time between surgery and conception, and BMI at the onset of pregnancy. A retrospective cohort study concerned 57 singleton pregnancies between 2011 and 2016 of 48 adult women who have undergone bariatric surgery. Small-for-gestational-age neonates were identified in 36.0% of pregnancies. With supplements intake (periconceptional period: 56.8%, trimester 1 (T1): 77.8%, T2: 96.3%, and T3: 100.0%), nutritional deficiencies involved vitamins A (T1: 36.4%, T2: 21.1%, and T3: 40.0%), D (T1: 33.3%, T2: 26.3%, and T3: 8.3%), C (T1: 66.7%, T2: 41.2%, and T3: 83.3%), B1 (T1: 45.5%, T2: 15.4%, and T3: 20.0%), and B9 (T1: 14.3%, T2: 0%, and T3: 9.1%) and selenium (T1: 77.8%, T2: 22.2%, and T3: 50.0%). There was no significant difference in the prevalence of nutritional deficiencies and complications according to surgery procedures and in the prevalence of pregnancy issues according to BMI at the beginning of the pregnancy and time between surgery and pregnancy. Prevalence of micronutritional deficiencies and small-for-gestational-age neonates is high in pregnant women following bariatric surgery. Specific nutritional programmes should be recommended for these women.

[Anticoagulation and peripartum management]. / Influence des anticoagulants sur la prise en charge péri-partum.

OBJECTIVE: To compare peripartum management of anticoagulated patients concerning locoregional analgesia, post-partum hemorrhage and thrombotic events according to planified interruption or not of antithrombotic therapy. PATIENTS AND METHODS: We conducted a single tertiary care center retrospective study of all deliveries associated with antithrombotic therapy from January 2005 to September 2011. RESULTS: We identified 120 cases with prophylactic (71%) or curative (29%) anticoagulation. Two thrombotic events occurred. In case of curative therapy, the use of locoregional analgesia was lower (P<0.0001) and post-partum hemorrhage occurred more frequently (P=0.07) compared to prophylactic therapy. According to planified interruption or not of antithrombotic therapy, we observed a more prolonged duration of therapeutic interruption before delivery (55.6h±63.3 vs 26.4 h±11.6, P<0.0001), higher use of locoregional analgesia (83% vs 71%, P=0.02) but no difference concerning cesarean rate (35% vs 39%, P=0.8) or post-partum hemorrhage (13% vs 14%, P=0.9). CONCLUSION: In case of curative anticoagulation, plannified interruption favours the use of perimedullar analgesia after 24hour delay. In case of preventive anticoagulation, plannified interruption appears unnecessary as the 12hour delay is easier to reach.

[Prelabour uterine torsion complicated by partial abruption and fetal death]. / Torsion utérine avant travail avec décollement placentaire et mort fœtale.

Uterine torsion is a rare obstetrical complication whose diagnosis remains challenging. We report a case of 180 degrees dextrogyre torsion at 36(+5) weeks of gestation complicated by partial abruption and in utero fetal death. Emergency cesarean section was performed through an unintentional posterior hysterotomy. Literature reports a few similar cases. Vertical hysterotomy should be advised in this context avoiding incision on lateral sides associated with increased risk of vascular or ureteral injury.

[Rupture of membranes: pathophysiology, diagnosis, consequences and management]. / Rupture des membranes : physiopathologie, diagnostic, conséquences et prise en charge.

Rupture of membranes (ROM) depends on mechanical stretch, extracellular matrix components imbalance and increased apoptosis. It occurs in 2 to 3% of all pregnancies before 37 weeks' gestation (WG) and in up to 10% at term. Main consequences are labor induction and risk of maternal-fetal infection. ROM is associated with one third of preterm births and about 20% of perinatal mortality. This review deals with recent knowledge concerning ROM including diagnosis and management. In many cases, ROM is easily identified by clinical examination. In other cases, the use of vaginal pH appears to be less efficient than the use of immunochromatographic strips based on IGFBP-1 or PAMG-1 detection. Before 34WG, conservative management consists in in utero transfer, antibioprophylaxis and corticosteroids. After 37WG, delivery is the most appropriate option. Between 34 and 37WG, recent studies demonstrate that induction of labour does not improve pregnancy outcomes. Therefore, expectant management can be the first option between 34 and 37WG when no active infection is suspected especially in case of unfavourable cervix.

[A policy of selective episiotomy in a ward: an example of medical professional assessment]. / Politique restrictive d'épisiotomie au sein d'un service : un exemple d'évaluation des pratiques professionnelles.

OBJECTIVES: To reduce the episiotomy rates, according to the Clinical Practice Guidelines, of 2005, from the French College of Obstetricians and Gynaecologists. PATIENTS AND METHODS: A cross sectional study was conducted, in the university hospital maternities (Maternity 1 and 2) with a retrospective record from medical files. Patients who had delivered in those maternities, by vaginal route, after 22 weeks amenorrhea were eligible. The global rate of episiotomy was analysed from 2006 to 2008. A descriptive clinical study was performed with a retrospective analysis (from July to December 2005 on 100 medical files and from July to December 2007 on 85 files). Besides, a study of episiotomy rate was conducted from 2006 to 2008. Improvement actions were developed between the two phases of assessment of the audit: sharing and comparing the results to standardized episiotomy rates, and elaborating an informatized regional perinatality file with episiotomy related items and national recommendations. RESULTS: Episiotomy rate decreased during the study, from 22.35% in 2005 to 19.34% in 2008, in the Ward 1 (p<0.0001) and from 33.62% in 2005 to 17.93% en 2008 (p<0.0001) in the Ward 2. An improvement was observed between the two periods of audits, for each item of the chart but without statistical signification. DISCUSSION AND CONCLUSION: Theses procedures have led to a positive impact on practices thanks to the work group and because of the politics of the perinatal network in favour of an episiotomy reduction. We hope these results could be improved in the future.

[Information and facilities recommendations concerning trial of labour in the context of scarred womb]. / Quelles sont les recommandations d'organisation et d'information en cas de proposition de tentative de voie basse pour utérus cicatriciel ?

OBJECTIVES: To precise key elements concerning facilities and patient information prior to trial of labour in the context of scarred womb. METHOD: Bibliographic search restricted to French and English languages using Medline database and recommendations of medical societies. RESULTS: Only expert's opinions are available. Patient information should present both trial of labour and elective cesarean section. Counselling should be influenced by individual risk of failed vaginal birth and uterine rupture. Mode of delivery should be planned the latest at 8 months of gestation. Patient should be aware of obstetrical and anesthetic facilities. Trial of labour should be presented as the first option for patients with no additional risk factors. Immediate presence of obstetrician and anesthesiologist is not required except in the context of increased risk for failed trial of labour or uterine rupture. Elective cesarean section on maternal request is acceptable after extensive counselling and delay of reflexion. CONCLUSION: Individual patient information should be initiated early and mode of delivery should be planned at 8 months of gestation. Resources and facilities recommendations aim to facilitate prompt cesarean section.

[Emergency cervical cerclage during mid-trimester of pregnancy: Experience of Clermont-Ferrand]. / Cerclage cervical en urgence au deuxième trimestre de la grossesse : expérience clermontoise.

OBJECTIVES: The objective of this study was to identify factors associated with favourable perinatal outcome after emergency cervical cerclage during mid-trimester of pregnancy. PATIENTS AND METHODS: This is a retrospective study of all cases who underwent emergency cervical cerclage between 16 to 28 weeks of gestation (WG) over a period of 16 years in a University Hospital. RESULTS: Among the 32 cases, the postnatal survival rate (day 28) was 80%. Delivery occurred at a mean gestational age of 33.1 WG [18-41.3 WG] and after 37 WG in 39% of cases. The perinatal outcome was improved by absence of bleeding (P=0.01), unripened cervix (P=0.02), cervical dilatation below 2 cm (P=0.002), no protruding membranes (P=0.02) and more advanced gestational age at the procedure (P=0.005). When no uterine contraction and no maternal blood inflammation were observed at admission, an expectancy of 48 hours before the procedure did not improve significantly perinatal outcome (gestational age at birth and survival rate [P=0.1 and P=0.3 respectively]). DISCUSSION AND CONCLUSION: Perinatal outcome after emergency cerclage depends on cervical status and gestational age at procedure. It is not influenced by an expectancy of 48 hours before intervention for patients with no uterine contraction and no maternal blood inflammation at admission.

[Favourable outcome after fetoscopic laser surgery for twin-twin transfusion syndrome: experience of an emerging centre]. / Résultats favorables d'une équipe émergente dans le traitement du syndrome transfuseur-transfusé par photocoagulation-laser.

OBJECTIVES: Our objective was to report perinatal outcome during the first three years of an emerging centre for laser photocoagulation in twin-twin transfusion syndrome (TTTS) and to compare with outcome observed earlier in the same centre when management consisted in recurrent amniodrainage. PATIENTS AND METHODS: We conducted a single centre retrospective study. We compared perinatal outcome of 19 consecutive cases of mid trimester TTTS managed by amniodrainage over a 10-year period with 49 cases of TTTS managed by laser photocoagulation over a 3-year period. RESULTS: Laser photocoagulation increased survival rate at birth (P=0.02) and at postnatal day 28 (P=0.01). Neurologic and cardiologic complications did not differ significantly (P=0.5 and P=0.3 respectively). We observed a significant increase in survival of the donor after laser coagulation at birth (P=0.04). DISCUSSION AND CONCLUSION: Our study demonstrated better outcome after laser photocoagulation. Early results of an emerging centre appeared comparable to those of more experienced centres.

[Learning curve of vacuum extraction in residency: a preliminary study]. / Courbe d'apprentissage de la ventouse obstétricale par les internes : étude préliminaire.

OBJECTIVES: The aim of this study was to assess the lurning curve of young residents for vacuum extraction. MATERIALS AND METHODS: All vacuum extractions performed in our department by five residents (< or =5th semester) during a study period of nine months were systematically supervised by a senior who fulfilled an assessment questionnaire from which was calculated a score reflecting the quality of the extraction. RESULTS: Fifty-four vacuum extractions were assessed with a mean of 10.8+/-2.9 (range, 10-13) procedures by resident. We compared the group including the six first procedures performed by each resident (group 1, n = 30) with the group including the following procedures (group 2, n = 24). We observed in the group 2 compared to the group 1, a significant improvement of the scores mean (12.3+/-5.4 vs 8.4+/-6.2, p = 0.016) and a significant reduction of the need for manual assistance by the senior (12.5% vs 40%, p = 0.034). CONCLUSION: We report a method for the learning and assessment of vacuum extraction feasible at "the bed" of the patient. This approach allows to observe a significant progression of the resident for the technique of vacuum extraction on a dozen of procedures.

[Sexual outcome after pelvic reconstructive surgery]. / Impact de la chirurgie réparatrice pelvienne sur la sexualité

Sexual well-being is an important parameter of women's health and quality of live. Sexual disorders may occur in women with pelvic organ prolapse and/or stress urinary incontinence and also after pelvic reconstructive surgery. Sexual dysfunction after POP or SUI surgery has been poorly documented but new condition specific questionnaires have been developed to help us to better evaluate such consequences. This paper reports available data and highlights more specifically consequences of surgery with mesh reinforcement which is, currently, an important issue particularly when performing by vaginal approach.

[What type of delivery for twins?]. / Quelle voie d'accouchement pour les jumeaux?

OBJECTIVES: To determine if perinatal and neonatal morbidity and mortality is improved by a planned caesarean section for twins before and at term. METHODS: A systematic search was conducted in Medline between May 2001 and December 2008. Randomised controlled studies and meta-analysis were researched at first. RESULTS: There is no evidence to support a policy of planned caesarean section or vaginal delivery for twins before term or at term whatever the presentation of the first twin. There is also no evidence to support a policy of caesarean section or vaginal delivery for a patient with a history of prior caesarean section. Vaginal delivery must be made in the presence of an obstetrician, an anaesthesiologist, and a paediatrician in a level maternity adapted to the risks of the future newborn. CONCLUSION: Otherwise, there is no evidence to support a policy of planned caesarean delivery for twins but the type of delivery has to be decided with the informed patient.

[Which invasive diagnostic procedure should we use for twin pregnancies: chorionic villous sampling or amniocentesis?]. / Quel prélèvement choisir pour les grossesses gémellaires: choriocentèse ou amniocentèse?

OBJECTIVE: To describe invasive diagnostic procedures (amniocentesis/choriocentesis) and subsequent risks in twin pregnancies. MATERIAL AND METHODS: PubMed and Cochrane database investigations were conducted using following key words: twin gestation, amniocentesis, chorionic villous sampling, karyotype. Guidelines for twin management edicted by different societies were reviewed. RESULTS: Risk of pregnancy loss after invasive diagnostic procedure in twin pregnancies seems to be slightly higher to singletons, i.e about 1.5-2% after mid-trimester amniocentesis and about 2% after first trimester choriocentesis. Dual sampling is not always mandatory but can be performed on parent's request. Specific risks are associated with twins: redundant sampling, permutation or misidentification of affected twin in case of discordant status. Procedures should be performed by highly-skilled operators under permanent ultrasound-guidance. A scheme describing placental locations and funicular insertions appears to be useful for correct identification. If foeticide can be anticipated, diagnostic procedure and foeticide should be performed by the same operators. For amniocentesis, one or two needles can be used except for cases with infectious disease (two needles and two separate insertions required). For choriocentesis, sampling should be performed close to funicular insertions. CONCLUSION: First-trimester choriocentesis makes earlier diagnosis and earlier foeticide possible compared with mid-trimester amniocentesis. Both techniques require highly-skilled operators to reduce subsequent risks in the context of twin pregnancies.

[Breech presentation and vaginal delivery: evolution of acceptability by obstetricians and patients]. / Accouchement du siège par voie vaginale: évolution de l'acceptabilité par les obstétriciens et les patientes.

OBJECTIVE: To investigate the influence of obstetrician and patient respectively on mode of delivery in case of breech presentation at term. PATIENTS AND METHODS: This retrospective study included all women with a singleton pregnancy in a breech presentation delivered at term in a tertiary care maternity unit from January 1998 to December 2004. Mode of delivery was suggested by a score based on maternal age, parity, obstetrical past history, radiopelvimetry and cephalopelvic confrontation. The obstetrician was free to follow or not the score indication and patient's informed consent was required concerning the mode of delivery. Our main outcome measurements were mode of delivery and neonatal parameters. RESULTS: Two hundred cases were identified. Elective cesarean section increased progressively (from 52% in 1998 to 80% in 2004 [P=0,002]). Neonatal status and proportion of score in favour of vaginal birth remained stable during the study period. The rise in cesarean section rate was mainly due to patient's request (P=0,001) whereas the trend of obstetrician in favour of cesarean did not reach significance (P=0,3). DISCUSSION AND CONCLUSION: The rise of elective cesarean section for term breech delivery in a maternity unit using a predefinite score is mainly induced by patient's request. This evolution has no effect on neonatal status.

[Neonatal morbidity after conservative management followed by systematic delivery at thirty-four weeks of gestation in preterm rupture of membranes]. / Morbidité néonatale après attitude d'expectative suivie d'une naissance systématique à 34 semaines d'aménorrhée en situation de rupture prématurée des membranes.

OBJECTIVE: To evaluate the neonatal morbidity and its risks factors in case of uncomplicated preterm rupture of membranes managed conservatively with subsequent planned delivery at 34 weeks of gestation. PATIENTS AND METHODS: We studied retrospectively 42 consecutive neonates systematically delivered at 34 weeks of gestation after more than 48 hours of conservative management for uncomplicated preterm rupture of membranes. Conservative management was conducted in a single tertiary care center and consisted in corticotherapy and in antibiotherapy (amoxycilline during 7 days). We evaluated the neonatal mortality rate, the incidence of infection, respiratory distress, neurological disorders, and we looked for their prenatal risks factors. RESULTS: Forty-two neonates were included. The median gestational age at rupture was 31.1 weeks of gestation (from 25 to 33.9 weeks). The median duration of expectant management was 20 days (from 2.4 to 65 days). We observed 7 cases of neonatal infection but no septic failure, 18 cases of respiratory distresses among which 9 required a tracheal intubation for a mean duration of 3.7 days, no perinatal encephalopathy (5 cases of subependymal haemorrhage) and no neonatal death. We isolated one single risk factor that was the lowest gestational age at rupture in case of subsequent respiratory distress (29.6 vs 31.9 weeks; P=0.02). DISCUSSION AND CONCLUSION: Neonatal morbidity in this population consisted mainly in respiratory distresses with an increased incidence when gestational age at rupture decreased.
