Fetoscopic laser coagulation for twin-twin transfusion syndrome before 17 weeks' gestation: laser data, complications and neonatal outcome.

OBJECTIVE: To compare laser data, complications and neonatal outcome in pregnancies that undergo 'early' (≤ 17 weeks' gestation) fetoscopic laser ablation of placental vascular anastomoses for twin-twin transfusion syndrome (TTTS) with those from 'conventional' cases treated after 17 weeks. METHODS: This was a cohort study of data collected prospectively between January 2004 and December 2012. We included monochorionic diamniotic twin pregnancies complicated by TTTS and treated by fetoscopic laser coagulation. Pregnancies were grouped according to laser treatment ≤ 17 gestational weeks or > 17 weeks and obstetric and neonatal outcomes were compared between groups. RESULTS: A total of 178 pregnancies with TTTS underwent laser therapy: 40 at or before 17 weeks and 138 after 17 weeks. There was no statistically significant difference between these two groups with respect to the rate of preterm prelabor rupture of membranes (PPROM), gestational age at PPROM and rate of PPROM occurring in the 7 days following fetoscopic laser coagulation. In the early group, the interval between performing fetoscopic laser coagulation and the time of delivery was significantly longer (104 days vs 74 days, P=0.0002) and the delivery rate within 7 days of laser treatment was significantly lower (2.5% vs 15.9%, P=0.026). There was no significant difference between the two groups with regard to the rates of pregnancy without live birth (15.4% vs 15.4%, P=0.993), with one live birth (84.6% vs 84.6%, P=0.993) and with two live births (64.1% vs 58.1%, P=0.500). CONCLUSION: In the event of early TTTS, fetoscopic laser coagulation is technically feasible before 17 gestational weeks and obstetric and neonatal outcomes are comparable with those in cases of laser treatment performed after 17 weeks.

Predictive value of cardiovascular parameters in twin-to-twin transfusion syndrome.

OBJECTIVE: To evaluate the prognostic value of the Children's Hospital Of Philadelphia (CHOP) cardiovascular score and the modified myocardial performance index (MPI), in determining the risk of recipient fetal loss in twin-to-twin transfusion syndrome (TTTS). METHODS: This cohort study was based on data collected prospectively from 105 pregnancies complicated by TTTS (Quintero stages I-IV) and treated with laser photocoagulation between May 2008 and February 2013. Fetuses underwent detailed anatomical and Doppler ultrasonography with cardiac assessment as part of routine care. CHOP score and right MPI were calculated and cut-offs selected using receiver-operating characteristics curve analysis. These were compared according to loss of recipient fetus, using univariate and multivariate logistic regression. The correlation between CHOP score, MPI and Quintero stage was determined and we investigated differences in MPI before and after laser coagulation in a cohort of 90 recipient fetuses. RESULTS: Rates of recipient fetal loss were significantly higher when the CHOP score was ≥ 3 (39.5% vs 12.9%, P = 0.002) and when MPI z-score was > 1.645 (34.5% vs 10.6%, P = 0.004). After adjustment for Quintero stage, the risk of recipient fetal loss remained significantly higher when the CHOP score was ≥ 3 (odds ratio, 3.09; 95% CI, 1.035-9.21). There was a positive correlation between CHOP score, MPI and Quintero stage. MPI was significantly lower after compared with before laser coagulation. CONCLUSION: CHOP score and MPI are predictors of recipient fetal loss in TTTS and may be used to supplement Quintero's classification.

Efficacy and safety of labour induction in patients with a single previous caesarean section: a proposal for a clinical protocol.

PURPOSE: To evaluate the efficacy and safety of induction in women with a single prior Caesarean section. METHODS: This was a cohort study in which we included all singleton pregnancies in patients with a single prior Caesarean who delivered between 2007 and 2012. Methods of induction were ocytocic infusion plus amniotomy (if Bishop score ≥6) or insertion of a Foley catheter (Bishop <6). RESULTS: Of the 2,075 patients included, 806 (38.8 %) had an elective repeat Caesarean, 1,045 (50.4 %) went into spontaneous labour, 89 (4.3 %) were induced by artificial rupture of the membranes and infusion of ocytocics and 135 (6.5 %) were induced using a Foley catheter. Rates of vaginal delivery were 79.2, 79.8 and 43.7 %, respectively. Six cases of uterine rupture were reported in the group of patients who went into spontaneous labour. There was no difference between groups with regard to neonatal morbidity. On multivariate analysis, risk factors for Caesarean delivery were macrosomia (OR 2.04, 95 % CI 1.31-3.18) and induction by Foley catheter (OR 3.73, 95 % CI 2.47-5.62); protective factors were previous vaginal delivery (OR 0.41, 95 % CI 0.29-0.57) and cervical dilatation (OR 0.84, 95 % CI 0.78-0.91). CONCLUSIONS: Uterine induction after a single Caesarean section with ocytocic infusion and amniotomy where the cervix is favourable does not appear to entail any significant added risk in terms of maternal or foetal morbidity. Foley catheter induction is a reasonable option if the cervix is not ripe.

Prediction of spontaneous preterm delivery in singleton pregnancies: where are we and where are we going? A review of literature.

Prematurity is the chief cause of neonatal morbidity and mortality. The objective of this study is to review the different methods for predicting preterm delivery in asymptomatic pregnant women and in situations of threatened preterm delivery. A search of the PubMed/Medline database was carried out for the years 1980-2012. We included studies for predicting preterm birth in asymptomatic and symptomatic patients. Models for predicting preterm delivery based on maternal factors, cervical length and obstetric history in first trimester of pregnancy is a valuable avenue of research. Nevertheless, prediction accuracy still needs to be improved. In the second and third trimesters, routine digital vaginal examination is of no value in asymptomatic women. Echography of the cervix is not useful except in patients with a history of late miscarriage or preterm delivery in order to offer them a preventive treatment. In symptomatic women, the combination of digital vaginal examination, cervical echography and fibronectin gives the best predictive results. Electromyography of the uterus and elastography of the cervix are interesting avenues for future research. Identifying patients at risk of preterm delivery should be considered differently at each stage of pregnancy.

Postnatal phenotype according to prenatal ultrasound features of Noonan syndrome: a retrospective study of 28 cases.

OBJECTIVE: Noonan syndrome is a frequent genetic disorder with autosomal dominant transmission. Classically, it combines postnatal growth restriction with dysmorphic and malformation syndromes that vary widely in expressivity. Lymphatic dysplasia induced during the embryonic stage might interfere with tissue migration. Our hypothesis is that the earlier the edema, the more severe postnatal phenotype. METHOD: This retrospective study analyzed data from all 32 cases of Noonan syndrome diagnosed in the Medical Genetics Department of Hautepierre Hospital in Strasbourg, France, between 1995 and 2011. The postnatal evolution of Noonan syndrome was compared according to the presence of at least one prenatal ultrasound feature of lymphatic dysplasia. RESULTS: The most frequent prenatal ultrasound features found were increased nuchal translucency, cystic hygroma and polyhydramnios; their global prevalence was 46.4%. The presence of these features was not significantly associated with the postnatal phenotype of Noonan syndrome. CONCLUSION: The results of our study indicate that prenatal ultrasound features of lymphatic dysplasia do not predict an unfavorable postnatal prognosis for Noonan syndrome.

Clinical and placental characteristics in four new cases of twin anemia-polycythemia sequence.

We report and analyze four new cases of spontaneous twin anemia-polycythemia sequence (TAPS) and discuss antenatal management by fetoscopic laser coagulation for this uncommon form of chronic intertwin transfusion. The clinical course and placental characteristics of four pairs of monochorionic-diamniotic (MCDA) twins with spontaneous TAPS, of which one was treated with fetoscopic laser surgery, are described. For the three cases that did not undergo intrauterine intervention, serial Doppler measurement revealed a gradual increase in the middle cerebral artery peak systolic velocity (MCA-PSV) in the donor and a concomitant decrease in the recipient. These twins were born at between 32 and 34 weeks' gestation by Cesarean section. At birth, the donor twins were severely anemic and the recipient twins were polycythemic. Placental injection studies revealed a few small arteriovenous (AV) and venoarterial anastomoses. In the fourth case, because of the high suspicion of TAPS on MCA-PSV data at 24 weeks' gestation, fetoscopic laser coagulation of three small AV anastomoses was successfully performed. No hematological abnormalities were detected at birth. TAPS is a newly described form of chronic twin-to-twin transfusion associated with chronic anemia in the donor and polycythemia in the recipient, without twin oligo-polyhydramnios sequence (TOPS). The monitoring of MCDA pregnancies should include measurement of MCA-PSV in both fetuses even in the absence of intertwin discordance in amniotic fluid volume. Early detection of TAPS could indicate fetoscopic laser coagulation of AV anastomoses.

[Outcome of in utero transfusion in case of fœtomaternal red blood cell incompatibility]. / Devenir obstétrical après transfusion in utero pour allo-immunisation fœto-maternelle.

OBJECTIVE: Erythrocyte allo-immunization's rate has decreased but without adapted treatment the prognosis is still poor. The aim of our study was to evaluate the fetal prognosis, the complication's rate and the risk factors of complications of the intrauterine transfusion. METHODS: Retrospective study about 37 fetus and 86 intrauterine transfusions between 2001 and 2017. Our main criterion in judging was the occurrence of procedure related complications: premature membrane rupture or premature delivery within seven days from the procedure, chorioamnionitis, abnormal fetal heart rate indicating an emergency ceasarean section within the 24hours from the procedure, in utero death or neonatal death related to the procedure. RESULTS: The survival rate was about 88.9% with a severe complication's rate of 5.8% per intrauterine transfusion and 13.5% per pregnancy. Intrauterine transfusions before 18 weeks of pregnancies was a complication risk factor: 50% of complications before 18 weeks vs. 1.3%, P=0.8×10-3. On the contrary, hydrops did not seem to be a complication risk factor (16.7% of complication with hydrops vs. 3.9%, P=0.27). The localisation of the needle insertion, intra-abdominal or placental insertion, had no effect on the fetal prognosis. CONCLUSION: Intrauterine transfusion complications are rare and it enhances the fetal prognosis. However, an early procedure is related to a higher rate of complications.

Expectant management and laser photocoagulation in isolated selective intra-uterine growth restriction: A single-center series.

INTRODUCTION: The objective was to report on a consecutive series of monochorionic diamniotic pregnancies complicated by selective Intra-Uterine Growth Restriction (sIUGR) and to describe perinatal outcomes based on whether or not there were umbilical Doppler findings, and specifically to study those pregnancies treated by laser. MATERIAL AND METHODS: This was a retrospective cohort study enrolling monochorionic diamniotic pregnancies presenting isolated sIUGR after 16 weeks' gestation (WG). RESULTS: Of the 25 cases of sIUGR, 16 were type I and 9 type II or III. Types II and III occurred earlier than type I (22.3 versus 24.3 WG), were more severe (discordance of 37% versus 23%), and delivered earlier (31.3 versus 33.9 WG). Survival was 12/18 (66.7%) for types II or III versus 32/32 (100%) for type I. Five laser photocoagulation procedures were attempted and allowed the survival of both twins in 2 cases. Overall survival after laser was 6/10 (60%). DISCUSSION: Isolated sIUGR is associated with high perinatal morbidity and mortality. Laser photocoagulation treatment is feasible and may enable survival of both twins in some cases, but may be technically difficult.

[Maternal morbidity and mortality associated with conservative management for placenta morbidly adherent (accreta) diagnosed during pregnancy. Report of 15 cases]. / Morbimortalité maternelle associée au traitement conservateur d'un placenta anormalement adhérent (accreta) diagnostiqué en anténatal. À propos d'une série continue de 15 cas.

BACKGROUND: High risk of morbidly adherent placenta increased during past years. Their management is controversial. Cesarean hysterectomy, considered the gold standard treatment by American Society, is associated with high risk of maternal morbimortality. Conservative management has been sought to reduce maternal morbidity associated with caesarean hysterectomy while maintaining fertility. It consists of leaving the placenta in place but long-term monitoring. Our main objective was to determine advantage/disadvantage of conservative management on patient with an antenatal diagnosis of placenta accreta, increta or percreta. MATERIAL AND METHODS: This retrospective study included all patients with an antenatal diagnosis of placenta accreta, increta or percreta between 2007 and 2014. Conservative treatment was systematically attempted according to our protocol. The primary outcome was defined as uterine conservation and the secondary outcome as maternal morbimortality defined as any medical or surgical condition occurring after childbirth. RESULTS: Fifteen patients (0.07 % of all living childbirths) were included. Conservative management was successful in 80 % of patients. There was no case of maternal death. Severe post-partum hemorrhage occurred in 4 patients (33.3 %) requiring uterine arteries embolization in one patient and hysterectomy in the 3 others. They underwent immediate blood transfusion of 13.5±4.5 average of red blood cell units. No severe septic condition occurred but 4 patients suffered from endometritis, 2.6±0.5 months after birth requiring intravenous antibiotics treatment in conventional hospitalization. Mean duration for spontaneous abortion of the placenta was 23.0±7.2 weeks. Three spontaneous pregnancies occurred in 2 patients after 19±16.9 months. CONCLUSION: Conservative management seems encouraging but is associated with a non-insignificant risk of secondary complication requiring long-term monitoring in conciliant patients.

[Accuracy of placenta accreta prenatal diagnosis by ultrasound and MRI in a high-risk population]. / Diagnostic anténatal des placentas accreta : apport de l'échographie et de l'IRM dans une population à risque.

OBJECTIVES: Main objective was to compare accuracy of ultrasonography and MRI for antenatal diagnosis of placenta accreta. Secondary objectives were to specify the most common sonographic and RMI signs associated with diagnosis of placenta accreta. MATERIAL AND METHODS: This retrospective study used data collected from all potential cases of placenta accreta (patients with an anterior placenta praevia with history of scarred uterus) admitted from 01/2010 to 12/2014 in a level III maternity unit in Strasbourg, France. High-risk patients beneficiated antenatally from ultrasonography and MRI. Sonographic signs registered were: abnormal placental lacunae, increased vascularity on color Doppler, absence of the retroplacental clear space, interrupted bladder line. MRI signs registered were: abnormal uterine bulging, intraplacental bands of low signal intensity on T2-weighted images, increased vascularity, heterogeneous signal of the placenta on T2-weighed, interrupted bladder line, protrusion of the placenta into the cervix. Diagnosis of placenta accreta was confirmed histologically after hysterectomy or clinically in case of successful conservative treatment. RESULTS: Twenty-two potential cases of placenta accreta were referred to our center and underwent both ultrasonography and MRI. All cases of placenta accreta had a placenta praevia associated with history of scarred uterus. Sensibility and specificity for ultrasonography were, respectively, 0.92 and 0.67, for MRI 0.84 and 0.78 without significant difference (p>0.05). The most relevant signs associated with diagnosis of placenta accreta in ultrasonography were increased vascularity on color Doppler (sensibility 0.85/specificity 0.78), abnormal placental lacunae (sensibility 0.92/specificity 0.55) and loss of retroplacental clear space (sensibility 0.76/specificity 1.0). The most relevant signs in MRI were: abnormal uterine bulging (sensitivity 0.92/specificity 0.89), dark intraplacental bands on T2-weighted images (sensitivity 0.83/specificity 0.80) or placental heterogeneity (sensitivity 0.92/specificity 0.89). Association of two sonographic or MRI signs had the best sensitivity/specificity ratio. DISCUSSION AND CONCLUSION: Ultrasonography and RMI represent two interesting and complementary diagnostic tools for antenatal diagnosis of placenta accreta. Because of its cost and accessibility, ultrasonography remains the first in line to be used for diagnosis. Use of an analytical grid for diagnosis of placenta accreta could be helpful.

[A rare case of caudal appendage]. / Appendice caudal dans l'espèce humaine : à propos d'un cas.

Caudal appendage is a rare malformation which has since ever been interesting. We present the case of a girl in which a caudal appendage was discovered before birth. A throughout checking found an extension from this abnormality to the cordal spine. The baby is operated when 2months old. Differential diagnosis are spina bifida, teratoma and pilonidal sinus. Caudal appendage is one of the typical cutaneous finding with underlying spinal dysraphism, such as hair tuft or pigmented macule. The risk is a tethered cord syndrome that can lead to severe complication. The treatment is either surgery or expectation.

Expression of prostacyclin and thromboxane synthases in placenta and placental bed after pre-eclamptic pregnancies.

Prostacyclin and thromboxane are potent antagonistic regulators of vascular tone and platelet aggregation. In pre-eclampsia, the ratio of their metabolites is decreased. Little is known about the local regulation of intrauterine prostacyclin and thromboxane production in this condition. Placenta and placental bed biopsies were obtained from uncomplicated and pre-eclamptic pregnancies. Prostacyclin synthase (PCS) and thromboxane synthase (TXS) and their mRNA's were localized by immunohistochemistry using monoclonal antibodies and in situ hybridization. Protein and mRNA levels were quantified by immunoblot and RNase protection assay. PCS-like immunoreactivity was found in endothelial cells and leiomyocytes, whereas fetal and maternal macrophages showed positive staining for TXS. Their mRNA was localized to trophoblast and endothelium, and TXS mRNA could also be detected in macrophages. Quantitative analysis showed no significant difference in intrauterine protein or mRNA expression after pre-eclampsia. The prostacyclin and thromboxane production seems to be compartmentalized within the uteroplacental unit. The expression of their synthesizing enzymes might be regulated post-transcriptionally. Additional regulation of prostaglandin production could be metabolically or on the substrate level and requires further elucidation.

A family with dominant oculoauriculovertebral spectrum.

In 1990, Gorlin et al. [Syndromes of the Head and Neck, New York: Oxford University Press, pp 641-649, 707-708] proposed to lump several syndromes together, including facioauriculovertebral syndrome, hemifacial microsomia, otomandibular dysostosis, Goldenhar syndrome, the first branchial arch anomalies and the first and second branchial arches anomalies. They proposed to use the term oculoauriculovertebral "spectrum." Because there is no agreement on minimal diagnostic criteria the phenotype overlaps many genetic and teratologic syndromes. Most cases are sporadic, but familial instances have also been observed in first-degree relatives. We report on a mother and two of her children who have the oculoauriculovertebral "spectrum." The mother had only auricular anomalies for which she had plastic and reconstructive surgery. Her first child, a girl, had a bilateral cleft lip and palate, a coloboma of upper eyelid, facial asymmetry, and posteriorly angulated ears. This child also had bilateral vesicoureteral reflux. During the second pregnancy fetal ultrasonographic examination performed at 18th week of gestation showed a cleft lip and palate. At the thirty-first week of gestation, club feet, hypoplasia of the left ear, hypoplasia of the left maxillary and mandibular arches, and left microphthalmia were evident. Examination of this fetus confirmed ultrasonographic findings and demonstrated vertebral anomalies. This familial observation confirmed variable expressivity of the oculoauriculovertebral anomaly with isolated microtia (the mother), major malformations (the fetus), and less serious anomalies (the first child) and showed that this condition may be inherited as an autosomal or X-linked dominant condition.

Antiphospholipid antibodies and preeclampsia: a case-control study.

OBJECTIVE: To assess the association between the occurrence first of preeclampsia and antiphospholipid antibodies. METHODS: We conducted a prospective case-control study of 180 pregnant women with their first incidents of preeclampsia and no histories of thrombosis or systemic autoimmune diseases. Preeclampsia (n = 180) was defined as blood pressure (BP) at least 140/90 mmHg after 20 weeks' gestation and proteinuria at least 0.3 g per 24 hours. Two control subjects were matched to each case (n = 360). They were pregnant women without hypertension or proteinuria and without histories of thrombosis or systemic autoimmune disease. Lupus anticoagulant (activated partial thromboplastin time, diluted thromboplastin time, platelet neutralization procedure) and anticardiolipin antibodies (immunoenzymatic assays) were assessed in both groups, and the coagulation state (levels of thrombin-antithrombin III complexes, fragments 1 + 2 of prothrombin) was also evaluated. The analysis design was a sequential plan with 5% type I error and 95% power. RESULTS: There was no association between antiphospholipid antibodies and preeclampsia. The odds ratio for the association was 0.95 (95% confidence interval 0.45, 2.61). Antiphospholipid antibodies were detected in eight of 180 preeclamptic women and in 19 of 360 controls. In contrast, there was a clear, confirmed activation of coagulation during preeclampsia. CONCLUSION: Despite evidence of a prothrombotic state during preeclampsia, it is unlikely that antiphospholipid antibodies (lupus anticoagulant and anticardiolipin antibodies) represent risk factors for preeclampsia among women with no previous preeclampsia and no histories of thrombosis or systemic autoimmune disease.

[Buprenorphine and pregnancy. Analysis of 24 cases]. / Grossesse et buprénorphine. A propos de 24 cas.

BACKGROUND: Maintenance therapy of drug-addict mothers with medical and psychosocial support may reduce complications (prematurity, growth retardation, fetal distress and fetal death). Methadone has been widely used during pregnancy with beneficial effects. Buprenorphine (BUP) is used more and more and shows the same beneficial effects. PATIENTS AND METHOD: Twenty-four pregnant women received BUP and their infants were enrolled in the study. Thirteen retrospective (GI) and 11 prospective (GII) cases were studied. In the GII, the women were treated and followed up in an interdisciplinary manner. RESULTS: Complications in GII were less frequent than in GI: 9 vs 30% of prematurity, 9 vs 46% of fetal growth retardation and 0 vs 23% of acute fetal distress. However, the frequency of withdrawal syndrome was the same in both groups, 63 vs 69%, though improvements came more rapidly in GII. CONCLUSION: This study shows that the use of BUP during pregnancy, combined with medical and psychosocial support, may reduce addiction complications. This support has to be maintained after the birth.

[Tetralogy of Fallot in monozygotic twins]. / Tétralogie de Fallot chez un couple de jumeaux monozygotes.

UNLABELLED: The causative mechanisms of congenital heart defects remain unclear and little is known about the respective implication of chance, genetics and environment, though recent findings in molecular biology may provide further insight into understanding the pathophysiologic basis of congenital heart diseases. CASE REPORT: We report the exceptional but significant case of monozygotic twins both affected by tetralogy of Fallot, for whom prenatal diagnosis ruled out 22q11 microdeletion. CONCLUSION: We discuss how far this observation is consistent with the latest hypothesis, which emphasizes the leading role of genetic factors. Several genes indeed, either separately or in combination, could be responsible for those defects, even if other influences may still come into play.

[Meckel syndrome. Update on a recurrent case]. / Le syndrome de Meckel. Mise au point a propos d'un cas récidivant.

Meckel's syndrome is an autosomal recessive disorder classically defined by occipital encephalocele, multicystic kidneys and polydactyly. However, a very wide phenotypic spectrum is characteristic of Meckel's syndrome. The prenatal diagnosis of this lethal syndrome is approached with ultrasound examination. The karyotype has to be done in order to make the differential diagnosis, especially with Trisomy 13 or 18. The rate of the Meckel's syndrome's gene is 1/400. The isolation of the specific gene will be soon helpful to define the Meckel's syndrome precisely.

[Prenatal and neonatal management of digestive tract duplications. Diagnostic difficulties and therapeutic implications]. / Prise en charge prénatale et néonatale des duplications digestives. Difficultés diagnostiques et implications thérapeutiques.

OBJECTIVE: To insist on the difficulty of the antenatal diagnosis of digestive duplications, to show the importance of a complete malformative screening, and the need for immediate management at birth. MATERIAL AND METHODS: A cystic duplication of the tongue, a duplication, abdomino-thoracic transdiaphragmatic, and a duplication of the small bowel are described and compared with cases previously reported in th literature. RESULTS: Antenatal evacuation puncture of a duplication of the tongue must be reserved for exceptional situations. Foregut duplications are often associated with other malformations. The duplication of the small intestine can exceptionally expose to a mechanical complication, mostly during the postnatal period, which may require emergency surgery. CONCLUSION: Duplications of the alimentary tract should be detectable on prenatal ultrasound examination. A complete antenatal malformative screening is required and in utero transfer is warranted because emergency surgery may be required.

[Ursodeoxycholic acid: prospect for treatment of gravidic cholestasis? Report of 3 cases]. / L'acide ursodésoxycholique: perspective de traitement de la cholestase gravidique? A propos de 3 observations.

Ursodeoxycholic acid, employed in treatment of intrahepatic cholestasis as seen in primary biliary cirrhosis, primary sclerosing cholangitis, and chronic hepatitis; does not have marketing approval for prescription during pregnancy because of lack of data. In 3 cases of gravidic cholestasis, we administered oral ursodeoxycholic acid 1 g a day from the 34th week of amenorrhea to delivery. In each case, it took 3 days of treatment for the pruritus to regress incompletely and for plasma levels of biliary acid and transaminases to decrease. The infants, born between the 36th and 38th week of amenorrhea, presented with no problem. Forty-eight cases of gravidic cholestasis treated by ursodeoxocholic acid (0.4 to 1 g a day) have been reported in the literature; 18 cases belonging to 2 randomized studies. In 46 cases pruritus disappeared generally 3 days after treatment onset, and plasma level of biliary acid and transaminase decreased in one week. Only two patients experienced persisting pruritus despite biological improvement. No foetal adverse effect is reported. Ursodeoxycholic acid seems to be an efficient treatment of gravidic cholestasis. Long term observation of fetuses exposed in utero to this treatment is required to assess safety.

[Abruptio placentae. Diagnosis, management and maternal-fetal prognosis: a retrospective study of 100 cases]. / Hématome rétroplacentaire. Diagnostic, prise en charge et pronostic maternofœtal: étude rétrospective de 100 cas.

OBJECTIVES: To update knowledge on placental abruption because there are few recent series published although the perinatal care has progressed. PATIENTS AND METHODS: A retrospective observational study has been conducted on 100 consecutive cases of abruptio placentae, occurring from January 2008 to June 2011, in the two maternity units of the University Hospital of Strasbourg (France). RESULTS: One hundred and five births among which five twin pregnancies were included. Clinical context was evident in 91% of cases, but the classic clinical triad was present in only 4% of cases. Clots were found at immediate placenta examination in 77% of cases. Pathological diagnosis was directly in accordance with clinical diagnosis in half the cases. Mean date of childbirth was 33 weeks of amenorrhea and 6 days. Sixty-seven patients gave birth prematurely. Among them, 50 patients delivered before 34 weeks. Sixty caesareans were performed in emergency before labor, including 47 with general anesthesia. Twelve patients had post-partum haemorrhage and ten coagulation disorders. There was no maternal death. Perinatal mortality was 19% with 13 fetal deaths in utero (12.4%), four children born in an apparent death state with resuscitation failure (3.8%) and three neonatal deaths (2.8%). DISCUSSION AND CONCLUSION: Placental abruption is a serious and unpredictable situation. Joint medical care of obstetricians and intensivists is often required. Perinatal mortality mainly occurs in utero.
