Abstract
BACKGROUND Predicting the bleeding risk in hemophilia A and B carriers (HAC, HBC) is challenging. OBJECTIVE The objectives of this study were to describe the bleeding phenotype in HAC and HBC using the standardized Tosetto bleeding score (BS); to determine whether the BS correlates better with factor levels measured with a chromogenic assay than with factor levels measured with chronometric and thrombin generation assays; and to compare the results in HAC and HBC. METHODS This ambispective, noninterventional study included obligate and sporadic HAC and HBC followed at a hemophilia treatment center between 1995 and 2019. RESULTS AND CONCLUSION The median BS (3, range 0-21 vs. 3.5, range 0-15, P = ns, respectively) and the abnormal BS rate (35.6% vs. 38.2%, P = ns) were not significantly different in 104 HAC and 34 HBC (mean age: 38 years, 6-80 years). However, some differences were identified. The risk of factor deficiency was higher in HBC than HAC. Specifically, Factor VIII activity (FVIII):C/Factor IX activity (FIX):C level was low (<40 IU/dl) in 18.3% (chronometric assay) and 17.5% (chromogenic assay) of HAC and in 47% and 72.2% of HBC ( P < 0.001). Moreover, the FIX:C level thresholds of 39.5 IU/dl (chronometric assay) and of 33.5 IU/dl (chromogenic assay) were associated with very good sensitivity (92% and 100%, respectively) and specificity (80% for both) for bleeding risk prediction in HBC. Conversely, no FVIII:C level threshold could be identified for HAC, probably due to FVIII:C level variations throughout life.

Which risk score best predicts cardiovascular outcome in pregnant women with congenital heart disease? EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2023; 9:177-183. [PMID: 35472215 DOI: 10.1093/ehjqcco/qcac019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 04/03/2022] [Accepted: 04/23/2022] [Indexed: 11/14/2022]
Abstract
BACKGROUND Management of pregnancy and risk stratification in women with congenital heart diseases (CHD) are challenging, especially due to physiological haemodynamic modifications that inevitably occur during pregnancy. AIMS To compare the accuracy of the existing pregnancy cardiovascular risk scores in prediction of maternal complications during pregnancy in CHD patients. METHOD AND RESULTS From 2007 to 2018, all pregnant women with a CHD who delivered birth after 20 weeks of gestation were identified. The discriminating power and the accuracy of the five existing pregnancy cardiovascular risk scores [CARPREG, CARPREG II, HARRIS, ZAHARA risk scores, and modified WHO (mWHO)] were evaluated.Out of 104 pregnancies in 65 CHD patients, 29% experienced cardiovascular complications during pregnancy or post-partum. For the five scores, the observed rate of cardiovascular events was higher than the expected risk. The values of area under the ROC curve were 0.75 (0.62-0.88) for mWHO, 0.65 (0.53-0.77) for CARPREG II, 0.60 (0.40-0.80) for HARRIS, 0.59 (0.47-0.72) for ZAHARA, and 0.58 (0.43-0.73) for CARPREG. CONCLUSION The modified WHO classification appeared to better predict cardiovascular outcome in pregnant women with CHD than the four other existing risk scores.Clinical Trial Registration: Clinicaltrials.gov: NCT04221048.

Abstract
INTRODUCTION In France, performance of a termination of pregnancy is legally possible without any gestational age limit. After 22 weeks of gestation, a feticide is ethically performed using usually sufentanil and lidocaine. The aim of this study was to compare the use of remifentanil, a fast-acting morphine-derivating product, instead of sufentanil. METHODS This 2-center randomized, controlled, single-blinded phase-III treatment trial had 2 parallel arms: an experimental group using remifentanil with lidocaine versus a control group receiving sufentanil associated with lidocaine. This trial took place over a 40-month period. The primary outcome was time to fetal asystole after lidocaine injection. The secondary outcome measures were the procedure's success rate, the rate of serious maternal side effects, and the presence of cellular or tissue modifications. RESULTS The study included 66 women, randomized into 2 groups of similar size and characteristics. Time to fetal asystole did not differ significantly between the groups, with a delay of 4 min (Q1-Q3, 2-11) in the sufentanil group and 4 min (Q1-Q3, 1-10) in the remifentanil group (p = 0.84). Similarly, the success rate of the procedure did not differ significantly. Fetal asystole was procured in <2 min and persisted >1 min for 16 (25.8%) women in our total population: 7 (22.5%) in the sufentanil group and 9 (29.0%) in the remifentanil group, p = 0.77. No severe maternal side effects were observed. Among the 49 fetopathological examinations performed, the few tissue and cell modifications observed did not cause any interpretation difficulties in either group. DISCUSSION/CONCLUSION Use of remifentanil instead of sufentanil for feticide procedure did not improve time to fetal asystole. No harmful effect was observed for either maternal tolerance or interpretation of the histologic slides.

A prospective cohort study of postpartum glucose metabolic disorders in early versus standard diagnosed gestational diabetes mellitus. Sci Rep 2021; 11:10430. [PMID: 34001938 PMCID: PMC8128886 DOI: 10.1038/s41598-021-89679-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 04/15/2021] [Indexed: 01/19/2023] Open
Abstract
Early gestational diabetes mellitus (eGDM) is diagnosed when fasting plasma glucose before 24 weeks of gestation (WG) is ≥ 5.1 mmol/L, whilst standard GDM is diagnosed between 24 and 28 WG by oral glucose tolerance test (OGTT). eGDM seems to have worse obstetric outcomes than standard GDM. We compared the rates of postpartum glucose metabolism disorders between women with early versus standard GDM in this prospective study on women with GDM from three university hospitals between 2014 and 2016. Patients were included if they were < 24 WG with at least one risk factor for GDM and excluded if they had type 2 diabetes. Patients were assigned to Group 1 (G1) for eGDM according to IADPSG: fasting blood glucose < 24 WG between 5.1 and 7 mmol/L. Group 2 (G2) consisted of patients presenting a standard GDM at 24–28 WG on OGTT results according to IADPSG: T0 ≥ 5.1 mmol/L or T60 ≥ 10.0 mmol g/L or T120 ≥ 8.5 mmol/L. The primary outcome was postpartum OGTT result. Five hundred patients were analysed, with 273 patients undergoing OGTT at 4–18 weeks postpartum: 192 patients in G1 (early) and 81 in G2 (standard). Patients in G1 experienced more insulin therapy during pregnancy than G2 (52.2% versus 32.5%, p < 0.001), but no patients were taking insulin postpartum in either group. G1 patients experienced less preterm labour (2.6% versus 9.1%, p = 0.043), more induced deliveries (38% versus 25%, p = 0.049) and reduced foetal complications (29.2% versus 42.0%, p = 0.048). There was no significant difference in the rate of postpartum glucose metabolism disorders (type 2 diabetes, impaired glucose tolerance, impaired fasting glycaemia) between groups: 48/192 (25%) in G1 and 17/81 (21%) in G2, p = 0.58. Thus the frequency of early postpartum glucose metabolism disorders is high, without difference between eGDM and standard GDM. This supports measurement of fasting plasma glucose before 24 WG and the threshold of 5.1 mmol/L seems appropriate until verification in future studies. Trial registration: NCT01839448, ClinicalTrials.gov on 22/04/2013.

Prenatal ultrasound diagnosis of cleft palate without cleft lip, the new ultrasound semiology. Prenat Diagn 2020; 40:1447-1458. [PMID: 32673416 DOI: 10.1002/pd.5794] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2020] [Revised: 07/01/2020] [Accepted: 07/09/2020] [Indexed: 11/12/2022]
Abstract
OBJECTIVES The aim of this study was to define the prenatal ultrasound semiology of cleft palate without cleft lip using 3D visualization of the fetal palate. METHODS A prospective longitudinal study was performed in our University Hospital Center from 2011 to 2018. The fetal secondary palate was studied in 3D, starting with 2D axial transverse ultrasound view. We defined a cleft palate as a disruption of the horizontal plate of the palatine bone of the secondary palate. Prenatal findings were correlated to anatomic postnatal examinations performed by a paediatric plastic surgeon. RESULTS Forty-three cases of cleft palate without cleft lip were prenatally diagnosed, of whom 34 were associated with malformations. We defined four types of disruptive appearances: isolated nonvisualization of the posterior nasal spine; partial-disruption or cleft velum; complete disappearance or V-shaped cleft palate; and complete disappearance or U-shaped cleft palate. The adjusted kappa coefficient, between prenatal and postnatal evaluation, was 0.88 (95% CI: 0.79-0.97), corresponding to an excellent agreement. CONCLUSIONS Using a strictly axial transverse ultrasound view, visualization of the secondary fetal palate enables to diagnose a cleft palate without cleft lip. This method offers a prenatal anatomic classification of cleft palate with a high level of concordance to postnatal findings.

Abstract
Physiological modifications of blood rheology during pregnancy and their alterations in pregnant hypertensive women have been extensively studied in the 1980's. Since vascular resistance is higher in hypertensive pregnant women whose newborns are small-for gestational-age (SGA), we investigated in a personal database if growth retardation of newborns is related to the oxygen delivery index (ratio hematocrit/blood viscosity) and to the difference between hematocrit (Hct) and the prediction of its optimal valued based on Quemada's equation. A sample of 38 hypertensive pregnant women (age 29 yr±1) was compared with 64 controls matched for age and gestational age, studied at 35±1 weeks gestation, extracted from a larger series of 162 pregnant women. On the whole the hypertensive group gave birth to smaller children (p = 0.014). Plasma viscosity correlated with blood pressure (BP) only in hypertensive women (r = 0.403 p < 0.05). The bell-shaped curve of predicted optimal Hct of non hypertensive pregnant women was similar to that of non-pregnant women, but in hypertensive women it was shifted toward higher values (p = 0.07), and the predicted optimal Hct (but not the actual one) was correlated with systolic blood pressure (SBP) (r = 0.349 p < 0.001) and diastolic blood pressure (DBP) (r = 0.218 p < 0.05). The predicted optimal Hct/viscosity (h/η) ratio was higher in hypertensive women whose newborns exhibited a low birth weight (p = 0.03), resulting in a higher discrepancy between actual and model-predicted «ideal» values of h/η ratio (p = 0.03) and Hct (p = 0.02) compared with the subgroup with no growth retardation. Therefore, in hypertensive women whose newborns exhibited a low birth weight, hemorheological parameters predicting oxygen supply are shifted to lower values than predicted by the model.

Abstract
OBJECTIVES To report the clinical spectrum of genital defects diagnosed before birth, identify predictive factors for severe phenotypes at birth, and determine the rate of associated malformations. PATIENTS AND METHODS A retrospective study (2008-2017) of 4580 fetuses, identified prenatally with abnormalities evaluated by our Reference Center for Fetal Medicine, included cases with fetal sonographic findings of abnormal genitalia or uncertainty of fetal sex determination. Familial, prenatal and postnatal data were collected via a standardised questionnaire. RESULTS In all, 61 fetuses were included. The positive predictive value (PPV) of the prenatal diagnosis of genital defects was 90.1%. Most cases were 46,XY-undervirilized boys, 42 cases (68.8%), which included 29 with mid-penile or posterior hypospadias, nine with anterior hypospadias, and epispadias, micropenis, scrotal transposition, and buried penis (one each). In all, 46,XX-virilized girls were identified in seven cases (11.5%), which included four with congenital adrenal hyperplasia, two with isolated clitoromegaly, and one with ovotestis. Other defects included prune belly syndrome and persistent cloaca (six cases). Early detection during the second trimester (58.1% vs 18.8%, P = 0.03), intra-uterine growth restriction (IUGR) (45.2% vs 9.1%, P = 0.06), and curvature of the penis (38.7% vs 0%, P = 0.02), were more frequently related to severe defects in male newborns. Associated malformations (14 cases, 22.9%) and genetic defects (six) were frequent in undervirilized boys. CONCLUSION Prenatal imaging of genital defects leads to a wide range of phenotypes at birth. Its PPV is high and extra-urinary malformations are frequent. Early diagnosis during the second trimester, associated IUGR, and curvature of the genital tubercle, should raise suspicion of a severe phenotype and may justify delivery near a multidisciplinary disorders/differences of sex development team.

Prognosis of severe congenital heart diseases: Do we overestimate the impact of prenatal diagnosis? Arch Cardiovasc Dis 2019; 112:261-269.

Abstract
BACKGROUND Prenatal diagnosis of congenital heart disease (CHD) is controversial because of unclear benefits in terms of morbidity and mortality, and issues with healthcare costs and organization. AIM To compare, in children with severe CHD, 1-year morbidity and mortality between prenatal and postnatal diagnosis groups. METHODS All pregnancies and children aged<1 year with a diagnosis of severe CHD were collected over a 5-year period from our database. Severe CHDs were defined as lethal cases, cases leading to medical termination of pregnancy, or children requiring surgery and/or interventional catheterization and/or hospitalization during their first year of life. The primary endpoint was 1-year mortality rate among live births. RESULTS Overall, 322 cases of severe CHD were identified; 200 had a prenatal diagnosis and there were 97 terminations of pregnancy. Of the 225 live births, 34 died before the age of 1 year. The 1-year mortality rate was not significantly different between prenatal and postnatal groups (16.7% vs. 13.9%; p=0.13). In the prenatal group, prostaglandin use was more important and precocious, duration of hospitalization stay was longer, extracardiac complications were less common and cardiac surgery was performed more frequently and later. An association with chromosomal or syndromic anomalies was a risk factor for 1-year mortality. CONCLUSIONS Prenatal diagnosis of severe CHD had an impact on the decision regarding termination of pregnancy, but not on the 1-year prognosis among live births. We should now use large multicentre CHD registries to determine the impact of prenatal diagnosis on postnatal management, neurological prognosis and quality of life.

Abstract
OBJECTIVE HELLP syndrome exposes to severe maternal and fetal complications. Prompt delivery is thus recommended after 34 weeks of gestation, or earlier in case of nonreassuring maternofetal conditions. However, no consensus has been raised in the treatment of HELLP syndrome occurring before 34 weeks of gestation, when both maternal and fetal conditions are stable: it remains still unclear whether an active attitude should be prioritized over expectant management. Herein, we aimed to compare mother and child outcomes according to the type of obstetrical management, either active or conservative. STUDY DESIGN Retrospective and multicenter study involving two tertiary care units. In Center A, obstetrical attitude consisted in expectant management: all women received full antenatal betamethasone therapy and pregnancy was prolonged until maternal or fetal follow up indicated delivery. In Center B, management was active: all deliveries were initiated within 48 hours following diagnosis. RESULTS From 2003 to 2011, 118 patients were included (87 in Center A, 31 in Center B). Both groups of patients were similar regarding maternal and fetal features at baseline. Active management led to increased risks of post-partum hemorrhage (relative risks (RR) = 5.38, 95%CI: 1.2-24.06) and neonatal morbidity including respiratory distress syndrome (RR = 3.1, 95%CI: 1.4-7.1), sepsis (RR = 2.5, 95%CI: 1.1-6.0), necrotizing enterocolitis (RR = 4.8, 95%CI: 1.1-21.2), intracerebral hemorrhage (RR = 5.4, 95%CI: 2.1-13.6), and blood transfusion (RR = 6.1, 95%CI: 1.7-21.7). CONCLUSIONS Conservative management may be beneficial for both mother and newborn in patients with stable HELLP syndrome. Identification of maternal and fetal specific prognostic factors would allow a better stratification of women with HELLP syndrome according to illness progressive potential, resulting in a more personalized management.

Abstract
Physiological studies on fetal blood in narrow glass tubes have suggested that fetal optimal hematocrit (hct) might be as high as 60%. A theoretical 'ideal' hct can also be predicted with a theoretical curve of hematocrit/viscosity (h/η) ratio vs hct constructed with Quemada's model. We used the database of one of our previous papers on fetal hemorheology to reinterpret its results with this concept. A series of 28 intrauterine cord punctures (between 19 and 33 weeks gestation) with doppler measurements of resistance in umbilical arteries was studied. The theoretical 'optimal hematocrit' was well correlated to actual (r = 0.857, p < 0.01) but systematically lower (Bland-Altman plot +12.1[8.52-15.7]) than the actual one. Umbilical artery resistance index is correlated with actual hematocrit (r = 0.407, p < 0.05), the discrepancy between ideal and actual (r = - 0.542, p < 0.05) but not predicted ideal hematocrit, suggesting that the discrepancy between ideal and actual may reflect an adaptative decrease aiming at reducing vascular resistance. These findings indicate that prediction of ideal hematocrit with Quemada's equation makes sense in fetal blood, and suggest that a 'viscoregulatory mechanism' maintains hematocrit below this theoretical value in order to avoid excess vascular resistance.

Abstract
OBJECTIVE It seeks to assess the appearance of the hysterorrhaphy area and seeks hematoma in asymptomatic patients at 48hours of their cesarean. METHOD It is common to see, ultrasound or CT scan, collection of images next to the hysterorrhaphy area in symptomatic patients after cesarean. Their interpretation remains difficult which led us to propose a prospective study looking for an evocative image collection or hematoma in asymptomatic patients at 48hours of their cesarean. It was directed suprapubic and transvaginal pelvic ultrasound with study area hysterorrhaphy and inter-uterine bladder space. RESULTS The suprapubic ultrasound examination was performed in 31 asymptomatic patients after collecting their written consent. Twenty-eight patients also received an endovaginal examination. The studied area was easily identified by visualizing the path of hysterotomy and hyperechoic aspect of the hysterorrhaphy. In 28 cases there were no abnormal image in front of the hysterorrhaphy area. In 3 cases, an evocative image of a haematic collection was displayed and measured a maximum of only 49mm long axis with a weak Doppler signal. The exam was very well tolerated by patients, especially by transvaginal route. Also the duration of ultrasound never exceeded 58seconds and remained fastest vaginally. CONCLUSION This preliminary work to a prospective double cohort (symptomatic patients and asymptomatic patients) has clarified the technique to use and focus in the search for a collection next to the hysterorrhaphy area. Ultrasound examination postoperatively, especially vaginally, is very fast, well tolerated with satisfactory image quality. Finally in this cohort of asymptomatic patients, it was very unusual for a collection, confirming the credit to be given to this type of image in case of symptoms after cesarean.

Abstract
IMPORTANCE Up-to-date estimates of the health outcomes of preterm children are needed for assessing perinatal care, informing parents, making decisions about care, and providing evidence for clinical guidelines. OBJECTIVES To determine survival and neonatal morbidity of infants born from 22 through 34 completed weeks' gestation in France in 2011 and compare these outcomes with a comparable cohort in 1997. DESIGN, SETTING, AND PARTICIPANTS The EPIPAGE-2 study is a national, prospective, population-based cohort study conducted in all maternity and neonatal units in France in 2011. A total of 2205 births (stillbirths and live births) and terminations of pregnancy at 22 through 26 weeks' gestation, 3257 at 27 through 31 weeks, and 1234 at 32 through 34 weeks were studied. Cohort data were collected from January 1 through December 31, 1997, and from March 28 through December 31, 2011. Analyses for 1997 were run for the entire year and then separately for April to December; the rates for survival and morbidities did not differ. Data are therefore presented for the whole year in 1997 and the 8-month and 6-month periods in 2011. MAIN OUTCOMES AND MEASURES Survival to discharge and survival without any of the following adverse outcomes: grade III or IV intraventricular hemorrhage, cystic periventricular leukomalacia, severe bronchopulmonary dysplasia, retinopathy of prematurity (stage 3 or higher), or necrotizing enterocolitis (stages 2-3). RESULTS A total of 0.7% of infants born before 24 weeks' gestation survived to discharge: 31.2% of those born at 24 weeks, 59.1% at 25 weeks, and 75.3% at 26 weeks. Survival rates were 93.6% at 27 through 31 weeks and 98.9% at 32 through 34 weeks. Infants discharged home without severe neonatal morbidity represented 0% at 23 weeks, 11.6% at 24 weeks, 30.0% at 25 weeks, 47.5% at 26 weeks, 81.3% at 27 through 31 weeks, and 96.8% at 32 through 34 weeks. Compared with 1997, the proportion of infants surviving without severe morbidity in 2011 increased by 14.4% (P < .001) at 25 through 29 weeks and 6% (P < .001) at 30 through 31 weeks but did not change appreciably for those born at less than 25 weeks. The rates of antenatal corticosteroid use, induced preterm deliveries, cesarean deliveries, and surfactant use increased significantly in all gestational-age groups, except at 22 through 23 weeks. CONCLUSIONS AND RELEVANCE The substantial improvement in survival in France for newborns born at 25 through 31 weeks' gestation was accompanied by an important reduction in severe morbidity, but survival remained rare before 25 weeks. Although improvement in survival at extremely low gestational age may be possible, its effect on long-term outcomes requires further studies. The long-term results of the EPIPAGE-2 study will be informative in this regard.

Abstract
AIM Create a record of the role given to members of the psychological professions in CPDPN Centers (multidisciplinary prenatal diagnosis). After more than 10 years in operation, describe the work methods of the different centers and their members, evaluate the possible diversity of practices and clarify the scope of interventions used by psychologists with patients and members of the CPDPN. METHOD A descriptive survey consisting of 71 questions sent to psychologists, paediatricians and psychiatrists involved with the 48 CPDPN Centers in France. The main parameters studied are the means used by the CPDPN and their organization in the field of psychology, pre-medical counseling for the termination of pregnancy (IMG), conditions of hospitalization and post-IMG counseling. RESULTS The survey revealed a high-level of homogeneous practices in the French CPDPN Centers between members of the medical and psychological professions, through joint consultations, ethical committees or specific case meetings for complex fetal pathologies. CONCLUSIONS AND PERSPECTIVES This study has established a working relationship between members of the psychological professions working in the French CPDPN Centers and has led to the creation of a listing/directory, which facilitates the exchange of information. Video-conferencing is currently being considered in order to share respective practices.

Abstract
We report a case of discordant phenotypic sex in monozygotic twins mosaic 47,XXY/46,XX: monozygotic heterokaryotypic twins. The twins presented with cognitive and comprehension delay, behavioural and language disorders, all symptoms frequently reported in Klinefelter syndrome. Molecular zygosity analysis with several markers confirmed that the twins are in effect monozygotic (MZ). Array comparative genomic hybridization found no evidence for the implication of copy number variation in the phenotypes. Ultrasound scans of the reproductive organs revealed no abnormalities. Endocrine tests showed a low testosterone level in Twin 1 (male phenotype) and a low gonadotrophin level in Twin 2 (female phenotype) which, combined with the results from ultrasound examination, provided useful information for potentially predicting the future fertility potential of the twins. Blood karyotypes revealed the presence of a normal 46,XX cell line and an aneuploïd 47,XXY cell line in both patients. Examination of the chromosome constitutions of various tissues such as blood, buccal smear and urinary sediment not surprisingly showed different proportions for the 46,XX and 47,XXY cell lines, which most likely explains the discordant phenotypic sex and mild Klinefelter features. The most plausible underlying biological mechanism is a post-zygotic loss of the Y chromosome in an initially 47,XXY zygote. This would result in an embryo with both 46,XX and 47,XXY cells lines which could subsequently divide into two monozygotic embryos through a twinning process. The two cell lines would then be distributed differently between tissues which could result in phenotypic discordances in the twins. These observations emphasize the importance of regular paediatric evaluations to determine the optimal timing for fertility preservation measures and to detect new Klinefelter features which could appear throughout childhood in the two subjects.

Partial lipodystrophy with severe insulin resistance and adult progeria Werner syndrome. Orphanet J Rare Dis 2013; 8:106.

Abstract
Background Laminopathies, due to mutations in LMNA, encoding A type-lamins, can lead to premature ageing and/or lipodystrophic syndromes, showing that these diseases could have close physiopathological relationships. We show here that lipodystrophy and extreme insulin resistance can also reveal the adult progeria Werner syndrome linked to mutations in WRN, encoding a RecQ DNA helicase. Methods We analysed the clinical and biological features of two women, aged 32 and 36, referred for partial lipodystrophic syndrome which led to the molecular diagnosis of Werner syndrome. Cultured skin fibroblasts from one patient were studied. Results Two normal-weighted women presented with a partial lipodystrophic syndrome with hypertriglyceridemia and liver steatosis. One of them had also diabetes. Both patients showed a peculiar, striking lipodystrophic phenotype with subcutaneous lipoatrophy of the four limbs contrasting with truncal and abdominal fat accumulation. Their oral glucose tolerance tests showed extremely high levels of insulinemia, revealing major insulin resistance. Low serum levels of sex-hormone binding globulin and adiponectin suggested a post-receptor insulin signalling defect. Other clinical features included bilateral cataracts, greying hair and distal skin atrophy. We observed biallelic WRN null mutations in both women (p.Q748X homozygous, and compound heterozygous p.Q1257X/p.M1329fs). Their fertility was decreased, with preserved menstrual cycles and normal follicle-stimulating hormone levels ruling out premature ovarian failure. However undetectable anti-müllerian hormone and inhibin B indicated diminished follicular ovarian reserve. Insulin-resistance linked ovarian hyperandrogenism could also contribute to decreased fertility, and the two patients became pregnant after initiation of insulin-sensitizers (metformin). Both pregnancies were complicated by severe cervical incompetence, leading to the preterm birth of a healthy newborn in one case, but to a second trimester-abortion in the other. WRN-mutated fibroblasts showed oxidative stress, increased lamin B1 expression, nuclear dysmorphies and premature senescence. Conclusions We show here for the first time that partial lipodystrophy with severe insulin resistance can reveal WRN-linked premature aging syndrome. Increased expression of lamin B1 with altered lamina architecture observed in WRN-mutated fibroblasts could contribute to premature cellular senescence. Primary alterations in DNA replication and/or repair should be considered as possible causes of lipodystrophic syndromes.

[Rupture of membranes in case of internal podalic version: a risk for cesarean section on the second twin]. GYNECOLOGIE, OBSTETRIQUE & FERTILITE 2012; 40:402-5.

Abstract
OBJECTIVES To evaluate if internal version with ruptured membranes is a risk factor of cesarean section for the second twin. PATIENTS AND METHODS Two hundred and fifty-nine twins vaginal deliveries after 33 weeks of gestation from 1997 to 2009 in a level 3 maternity. A retrospective case-control study comparing two groups: cases of cesarean section on second twin and five twins vaginal deliveries following the case. Active management of the second twin delivery was performed with a short intertwin delivery. RESULTS Eleven cesarean sections on the second twin were performed (4.2%). The main indication was failure of internal version. The risk of cesarean section was significantly greater when the internal version was performed with ruptured membranes (OR: 25.4 IC 95% [2.3-275.7] P<0.003) and when intertwin time delivery interval was increased (8.1±5.1 vs 16.7±6.3, P<0.001). DISCUSSION AND CONCLUSION The rupture of amniotic membranes before or during the internal podalic version is associated with a risk of failure and cesarean for the second twin. We recommend to perform the internal podalic version with unruptured membranes according to the French recommendations.

Abstract
OBJECTIVES To audit French maternity units' obstetric procedures in delivering women who have undergone previous caesarean section. MATERIAL AND METHODS [corrected] Survey by questionnaire collecting the obstetrical practices about agreement and methods of delivery of women with previous caesarean section in France in 2009. The questionnaire was sent by email to 472 private and public maternity units of grades 1, 2 and 3. RESULTS One hundred and seventy-five units (37%) replied, about 305,710 new-borns representated, few private maternity units answered (12.6% of the answers), despite their accounting for 30.2% of obstetric work; 50.9% had no written policy for the management of patients with previous caesarean; 53.1% of units relied on written consent from women attempting vaginal delivery after previous caesarean. The documentation concerning previous caesarean section was considered important by 73.1% of units. Rates for acceptance of attempted vaginal delivery were as follows: after a transverse lower uterine segment incision - 100% of maternity units; after a transverse corporeal incision - 30.3% of units and after a vertical incision - 25.1% of units; 55.4% of maternities induced labour after a previous caesarean section, 29.9% of them with prostaglandin E2; 64% used internal tocometry. Radiopelvimetry was a routine examination for 55.9% of grade 1 units, compared with 13.5% of grade 3 (P=0.000035). Induction was practised by more grade 3 units (78.3%) than grade 1 units (44%) (P=0.009). No team acknowledged carrying out subsequent caesarean delivery as a matter of principle. CONCLUSIONS This national survey, statistically representative in terms of the numbers of deliveries, gives an objective view of different practices, according to type and grade of maternity unit in France, in 2009. The data indicate that it is desirable to devise specific recommendations in order to harmonise management, bearing in mind the frequency of caesarean sections.

Abstract
OBJECTIVE To investigate the accuracy of prenatal axial three-dimensional (3D) ultrasound in predicting the absence or presence of cleft palate in the presence of cleft lip. METHODS Between March 2005 and January 2009, there were 81 cases with a prenatal two-dimensional (2D) ultrasound screening diagnosis of unilateral or bilateral cleft lip at 22-25 weeks of gestation referred to our tertiary care center. Of these, 79 fetuses were included in this prospective study and two were excluded. Axial 3D ultrasound imaging of the fetal palate was performed and the diagnoses were compared with clinical findings at delivery. The frequencies of intact and cleft palate, the degree of association between the prenatal predictions and postnatal findings and the probability of detection of cleft lip and palate were determined. RESULTS Of 79 prenatal predictions, 77 (97%) were correct and the association between the prenatal predictions and postnatal findings was strong. The sensitivity for detection of cleft lip and palate within this high-risk population was 100% and the specificity was 90%. In one of the excluded cases, the palate could not be visualized due to a fetal prone position. There were chromosomal anomalies in 4% of cases and associated structural or growth anomalies in 23%, termination of pregnancy was carried out in 4% and intrauterine fetal demise occurred in 3%. CONCLUSION Axial 3D ultrasound of the fetal palate has high accuracy in identifying prenatal cleft palate when cleft lip is diagnosed at mid-trimester 2D ultrasound screening.

Abstract
OBJECTIVE To determine the prevalence and the timing of pregnancy termination relative to the type of central nervous system (CNS) malformations. Design Retrospective cohort study. SETTING Multidisciplinary centre for prenatal diagnosis in the Languedoc-Roussillon region, France. POPULATION A cohort of 481 pregnancy terminations performed between 2005 and 2009. METHODS Detailed post-termination fetal and neuropathological analyses were carried out to identify the CNS malformations. Then, the prevalence and timing of pregnancy termination were assessed relative to the identified malformations. RESULTS About one-third of pregnancy terminations (143/481) were performed for severe CNS malformations. Up to 24 weeks of gestation (WG), pregnancy terminations (56.6%) were carried out mainly for defects occurring during the two major first steps of CNS development (neurulation and differentiation of cerebral vesicles). After 24 WG, pregnancy terminations (43.3%) were mainly performed for corpus callosum agenesis (16/17), vermian agenesis (10/12) and gyral anomalies (13/15). For hindbrain malformations and gyral anomalies, there was a significant relationship between the timing of pregnancy termination and the presence of a severe ventriculomegaly at prenatal diagnosis (p=0.002 and p=0.02, respectively). CONCLUSION By classifying CNS malformations according to the neuropathological analysis, the authors show that the timing and prevalence of pregnancy termination are distributed in a manner that is consistent with what is currently known on the development of brain. They are also influenced by the French prenatal screening policy and the variable expressivity of the brain malformations and associated lesions.

Abstract
We report the case of a large leg tumor in a fetus at 36 weeks of gestation. The tumor's location, ultrasound characteristics and magnetic resonance imaging (MRI) findings enabled a prenatal diagnosis of congenital fibrosarcoma and allowed us to establish the prognosis. After multidisciplinary discussion, it was decided that the pregnancy should continue to 38 weeks, with surgery or neo-adjuvant chemotherapy scheduled after delivery. Unfortunately, the tumor unexpectedly burst in utero and the newborn died of the consequences of hemorrhagic shock, despite rapid amputation. Histological examination confirmed the nature of the tumor. The prognosis of congenital fibrosarcoma is generally good when there are no metastases. MRI is key to establishing a prenatal diagnosis. However, rupture of the tumor can result in fatal hemorrhaging and the pregnancy should be monitored closely before scheduled delivery.

Abstract
Inherited disorders of fibrinogen are rare and affect either the quantity (hypofibrinogenaemia and afibrinogenaemia) or the quality of the circulating fibrinogen (dysfibrinogenaemia) or both (hypodysfibrinogenaemia). Extensive allelic heterogeneity has been found for all these disorders: in congenital afibrinogenaemia for example more than 40 mutations, the majority in FGA , have been identified in homozygosity or in compound heterozygosity. Numerous mutations have also been identified in patients with hypofibrinogenaemia, many of these patients are in fact heterozygous carriers of afibrinogenaemia mutations. Despite the number of genetic analyses performed, the study of additional patients still allows the identification of novel mutations. Here we describe the characterization of a novel FGA intron 2 donor splice-site mutation (Fibrinogen Montpellier II) identified in three siblings with hypodysfibrinogenaemia. Functional analysis of RNA produced by the mutant minigene in COS-7 cells revealed that the mutation led to the in-frame skipping of exon 2. Western blot analysis of COS-7 cells expressing an exon 2 deleted FGA cDNA revealed that an alpha-chain lacking exon 2, which codes in particular for fibrinopeptide A and polymerisation knob 'A', has the potential to be assembled into a hexamer and secreted. Analysis of precipitated fibrinogen from patient plasma showed that the defect leads to the presence in the circulation of alpha-chains lacking knob 'A' which is essential for the early stages of fibrin polymerisation. Fibrin made from purified patient fibrinogen clotted with thrombin displayed thinner fibers with frequent ends and large pores.

Abstract
BACKGROUND Early postpartum discharge is a recent practice in France, but the influence of a shortened hospital stay on subsequent breastfeeding is unknown. The objective of the present study was to compare the breastfeeding mode after early discharge (ED) and conventional discharge (CD) from a hospital maternity unit. METHODS An observational study was conducted in a French university hospital among 135 breastfeeding mothers, who delivered between 1 January and 31 July 2006. Forty-five ED mothers were matched with 90 CD mothers on 13 criteria. A structured questionnaire was used to collect data regarding feeding practices at 10 weeks postpartum, the period corresponding to paid maternity leave. RESULTS Exclusive breast-, mixed, and bottle feedings were reported by, respectively, 35 (77.8%), three (6.7%) and seven (15.5%) ED mothers and 64 (71.1%), 12 (13.3%) and 14 (15.6%) CD mothers (no significant differences). Satisfaction with support for breastfeeding and reasons for switching to mixed or bottle feeding were comparable in the two groups. Multivariate analysis indicated that only the planned duration of breastfeeding and the mother's dissatisfaction with help significantly influenced breastfeeding prevalence. CONCLUSIONS Early postpartum hospital discharge organized by skilled professionals is compatible with a satisfactory rate of exclusive breastfeeding up to the return to work. Formalized programs of instruction for perinatal professionals would help to reduce early abandonment.

Abstract
OBJECTIVES To describe a three-dimensional (3D) ultrasound technique for assessing the fetal soft palate. METHODS A prospective study conducted from April to December 2006 included 87 fetuses in a low-risk population. Fetal ultrasound scans were performed between 21 and 25 weeks of gestation to determine the normal 3D ultrasound view of the fetal soft tissues of the palate. The sonographers used a 30 degrees-inclined axial 3D view of the fetal palate. Ultrasound images obtained in this view were compared with fetopathological specimens of the same gestational age by two observers, both pediatric surgeons. Each observer indicated whether they thought that the uvula or the velum could be detected, and the differences in responses between the observers were assessed. RESULTS The frequencies of detection of the uvula and velum of each observer varied between 80% and 90%. The observers showed a significant difference in judging the visualization of the uvula, but not in judging the velum. CONCLUSIONS A 30 degrees -inclined axial 3D ultrasound view seems to be effective in assessing the integrity of the fetal soft palate.

Abstract
AIM To evaluate the use of arterial embolization in postpartum hemorrhage (PPH) by comparing the indications, efficacy, times to diagnosis, treatment, and embolization, and conditions of management of patients before and after publication of the Collège National des Gynécologues et Obstétriciens Français clinical practice recommendations (CPR). METHODS Forty-eight patients who underwent embolization between January 2000 and December 2005 were included in a retrospective, descriptive, and comparative study. We compared the management before (n=21) and after (n=27) publication of the CPR. The main outcome measures were time to diagnosis of PPH, time to treatment initiation, time to decision to implement embolization, time to embolization, hemodynamic characteristics. RESULTS The number of embolizations has quadrupled since publication of the CPR, and the time taken to decide on embolization has been reduced by 30%. The success rate was 96%, there were no second embolization procedures, and one complication was recorded (hematoma of pubic symphysis). Hemodynamic status was better in patients treated after the CPR (P=0.003). CONCLUSION Embolization is an effective and safe technique, with a low complication rate. In our healthcare network, the decision to use embolization was faster since the CPR, embolizations have quadrupled, and patients' hemodynamic status has improved.

Abstract
As the prevalence of obesity grows in western countries, maternal obesity is becoming an increasingly frequent high-risk obstetrical situation. Obese women have a higher incidence of pregnancy complications (gestational diabetes, hypertension, toxaemia, etc.) and of adverse fetal outcomes (macrosomia, neural tube defects, perinatal mortality). Cesarean section is more frequent in obese women, resulting in a higher risk of anaesthetic and post-operative complications. Maternofetal complications are proportional to the degree of obesity, and even moderate overweight amplifies the risk. Long-term complications include worsening of maternal obesity, maternal type 2 diabetes, and childhood obesity and metabolic disorders. Before conception, these patients should receive tailored weight-loss advice and be screened for obesity complications. Food intake during pregnancy should be tailored to achieve the minimum maternal weight gain required for normal fetal growth. Long-term follow-up is required to prevent worsening of maternal obesity after delivery, and the child's growth curve should be closely watched

Abstract
The obesity epidemic is of some concern in women of reproductive age. Maternal obesity is associated with many pregnancy complications, especially gestational diabetes and hypertensive disorders of pregnancy. Delivery in obese women is characterized by a high caesarean-section rate and an increased risk of anaesthetic and postoperative complications. Weight retention after birth may increase the risk of type 2 diabetes in the long term. Foetal risks include macrosomia, malformations and increased perinatal mortality, with the long-term infant health marked by a higher risk of obesity and metabolic disorders. Optimal management includes preconception counselling, pregravid weight-loss programmes, monitoring of gestational weight gain, repeated screening for pregnancy complications and long-term follow-up to minimize the social and economic consequences of pregnancy in overweight women.

Abstract
We report on a 35-year-old woman who underwent at 15 weeks of pregnancy exclusive parenteral nutrition for recurrent episodes of acute pancreatitis. She had a pancreatico-jejunal anastomosis stenosis secondary to cephalic duodenopancreatectomy. Nocturnal exclusive parenteral nutrition was used 79 days during pregnancy and 12 days during post-partum. The fetal growth was normal and the foetal well-being was normal. She presented cholestasis at 30 weeks of pregnancy treated medically. She delivered at 33 weeks of pregnancy by cesarean section a healthy baby girl with normal birth weight.

Abstract
PURPOSE Drug abuse during pregnancy is an important public health problem. Montpellier University Hospital established a center for addiction and pregnancy in 1997 to provide multidisciplinary prenatal care aimed at reducing maternal and fetal risks during pregnancy and afterwards. This study assesses the trends in drug-taking behavior and pregnancy outcome among women receiving this prenatal care. METHODS This exploratory prospective study examined participants in this program during its first 5 years (1997-2002). Women were included if they had been: pregnant, addicted to opiates, enrolled in the program for at least 15 days, and if their delivery took place at Montpellier Hospital. We recorded how often they came to prenatal care, drug-taking behavior, social and economic level, and obstetrical and neonatal outcomes. RESULTS The study included 114 women. Those receiving drug substitution at the onset of pregnancy mainly saw general practitioners (64/89 at the beginning of pregnancy), who most often prescribed buprenorphine (70/105 at the end of pregnancy). More than two thirds of patients (n=78) abused several substances. Heroine abuse decreased (p<0.01) over pregnancy, and social and economic level rose (p<0.001). Mean gestational age at delivery was 38.5 weeks. Neonatal withdrawal syndrome remained an important problem and required treatment in 89 infants (78%). No mothers abandoned their infant. CONCLUSION Multidisciplinary prenatal care with medical, social, and psychological support can decrease opiate abusers' risks during pregnancy even when the drug treatment program is essentially unsupervised.

Abstract
OBJECTIVES The aim of this study was to describe a novel three-dimensional (3D) ultrasound rendering technique to examine the normal fetal posterior palate and to assess its correspondence with the real fetal anatomy. METHODS A prospective longitudinal study was conducted from January to October 2005 and included 100 fetuses in a low-risk population. Fetal ultrasound examinations were performed at 17, 22, 27 and 32 weeks' gestation to determine the normal 3D ultrasound view of the fetal palate at different gestational ages. The ultrasound scans were performed using the strict anterior axial plane of the starting reconstruction volume and the underside 3D view of the fetal palate. The 3D view of the fetal palate was compared with the normal anatomical view of the fetal palate obtained by surgical fetopathological examination of fetuses at the same gestational ages. The sonographic visualization rates of seven defined anatomical landmarks of the fetal palate were computed for each gestational age. The visualization rates across gestational ages were compared by use of the Cochrane Q test. The reliability of detection of each anatomical landmark across gestational ages was determined by Cronbach's Alpha. RESULTS In all cases a 3D ultrasound view of the fetal maxilla and secondary palate was obtained at each period of gestation and corresponded well to the fetal anatomical specimens. The seven defined anatomical landmarks of the fetal palate were identified in 42-100% of cases. The visualization rates across gestational ages were significantly different in five of these anatomical landmarks. These differences can be explained by different developmental processes of these anatomical structures. The overall reliability of visualization across the gestational ages for the anatomical landmarks was medium to very high (0.73-0.96), except for the landmark interpalatal suture which was low (0.48). CONCLUSIONS This technique of anterior axial 3D view reconstruction of the fetal palate seen by an underside view can provide unique diagnostic information on the integrity of the secondary palate. This innovative, simple and rapid technique may become the reference technique in ultrasound investigation of the fetal palate, and should be of value in diagnosing isolated secondary cleft palate or palatal involvement when cleft lip and alveolus are diagnosed.

Abstract
OBJECTIVES To evaluate the risk of very preterm birth (22-32 weeks of gestation) associated with previous induced abortion according to the complications leading to very preterm delivery in singletons. DESIGN Multicentre, case-control study (the French EPIPAGE study). SETTING Regionally defined population of births in France. SAMPLE The sample consisted of 1943 very preterm live-born singletons (< 33 weeks of gestation), 276 moderate preterm live-born singletons (33-34 weeks) and 618 unmatched full-term controls (39-40 weeks). METHODS Data from the EPIPAGE study were analysed using polytomous logistic regression models to control for social and demographic characteristics, lifestyle habits during pregnancy and obstetric history. The main mechanisms of preterm delivery were classified as gestational hypertension, antepartum haemorrhage, fetal growth restriction, premature rupture of membranes, idiopathic preterm labor and other causes. MAIN OUTCOME MEASURES Odds ratios for very preterm birth by gestational age and by pregnancy complications leading to preterm delivery associated with a history of induced abortion. RESULTS Women with a history of induced abortion were at higher risk of very preterm delivery than those with no such history (OR + 1.5, 95% CI 1.1-2.0); the risk was even higher for extremely preterm deliveries (< 28 weeks). The association between previous induced abortion and very preterm delivery varied according to the main complications leading to very preterm delivery. A history of induced abortion was associated with an increased risk of premature rupture of the membranes, antepartum haemorrhage (not in association with hypertension) and idiopathic spontaneous preterm labour that occur at very small gestational ages (< 28 weeks). Conversely, no association was found between induced abortion and very preterm delivery due to hypertension. CONCLUSION Previous induced abortion was associated with an increased risk of very preterm delivery. The strength of the association increased with decreasing gestational age.

Abstract
OBJECTIVE: To report a child born with renal impairment following severe anhydramnios due to maternal exposure to an angiotensin II receptor type 1 (AT1) antagonist, valsartan, and hydrochlorothiazide during the first 28 weeks of pregnancy. CASE SUMMARY: A hypertensive woman treated with valsartan 80 mg/day, hydrochlorothiazide 12.5 mg/day, prazosin 10 mg/day, lysine acetylsalicylate 100 mg/day, and levothyroxine 250 μg/day became pregnant. At 28 weeks' gestational age, severe anhydramnios associated with high β2-microglobulin levels in the fetal blood cord was observed. Upon discontinuation of valsartan, fetal renal prognosis improved. In this case, using the Naranjo probability scale, the renal insufficiency of the child was probably related to valsartan. At the age of 2.5 years, the child presented with only mild chronic renal insufficiency. Growth parameters were within the normal range, and there was no evidence of developmental delay. DISCUSSION: Exposure to AT1 antagonists during the second part of pregnancy can lead to abnormalities similar to those observed after exposure to angiotensin-converting enzyme inhibitors, that is, reduced fetal kidney perfusion that may result in oligoamnios and neonatal renal insufficiency. Fourteen previous reports of maternal exposure to AT1 antagonists during this period have been published. In 6 cases, fetal or neonatal death occurred; in 2 cases, pregnancy was terminated because of complete anhydramnios or fetal abnormalities; in 1 case, renal insufficiency persisted at 8 months of age; in 2 cases, kidney function was fairly normal at birth; and in 4 cases, including the one described here, neonatal renal failure improved in the first year of life. CONCLUSIONS: AT1 antagonists should be avoided throughout pregnancy. If these agents are prescribed accidentally to a pregnant woman, monitoring of amniotic fluid volume and β2-microglobulin fetal blood levels after discontinuation of the AT1 antagonist can provide critical data for advising parents on pregnancy and fetal outcome.

Abstract
OBJECTIVES Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a usually lethal disease during the first year of life. There is no specific ultrasound prenatal diagnosis and no identified genetic locus. The value of amniotic fluid digestive enzyme assay and fetal urine biochemistry in the prediction of MMIHS was analysed. METHODS Retrospective study of 14 MMIHS cases. Amniotic fluid digestive enzymes and fetal urine biochemistry were compared in MMIHS and megabladder (63 and 264 cases respectively). RESULTS Abnormal amniotic fluid digestive enzyme profile (vomiting of bile or digestive secretion leakage) was observed in 8/10 MMIHS cases. These profiles were observed in 7/63 controls; 80% sensitivity (95%CI = 55%-100%); 89% specificity (95%CI = 81%-96%). Fetal urinalysis was normal in 12/12 MMIHS cases except high calcium (>0.6 mmol/l). This profile was observed in 33/264 megabladder control cases; 100% sensitivity; 98.7% specificity (95%CI = 83.5%-91.5%). CONCLUSION For the first time, we propose a prenatal diagnosis of MMIHS based on amniotic fluid digestive enzyme assay and on fetal urinalysis.

Abstract
OBJECTIVE To evaluate perinatal outcome in pregnancies in women with type 1 and type 2 diabetes and the influence of preconception care 10 years after the St. Vincent's declaration. RESEARCH DESIGN AND METHODS A cross-sectional study was conducted in 12 perinatal centers in France in 2000-2001. The main investigated outcomes were perinatal mortality, major congenital malformations, and preterm delivery. RESULTS Among 435 single pregnancies, 289 (66.4%) were from women with type 1 and 146 (33.6%) from women with type 2 diabetes. Perinatal mortality rate was 4.4% (0.7% national rate), severe congenital malformations rate was 4.1% (2.2% national rate), and preterm delivery rate was 38.2% (4.7% national rate). Preconception care was provided in 48.5% women with type 1 diabetes and in 24.0% women with type 2 diabetes. Women whose first trimester HbA(1c) was >8% had higher rates of perinatal mortality (9.2 vs. 2.5%; odds ratio 3.9; 95% CI 1.5-9.7; P < 0.005), major congenital malformations (8.3 vs. 2.5%; 3.5; 1.3-8.9; P < 0.01), and preterm delivery (57.6 vs. 24.8%; 1.4; 1.1-1.7; P < 0.005) than those with first trimester HbA(1c) <8%. These results are similar to those reported in France in 1986-1988. CONCLUSIONS Pregnancies in women with diabetes are still poorly planned and complicated by higher rates of perinatal mortality and major congenital malformations. Despite knowledge of the importance of intensified glycemic control before pregnancy, reaching the St. Vincent's target needs further implementation in France.

Abstract
OBJECTIVE To define the diagnostic and therapeutic value of foetal urine sampling (FUS). MATERIAL AND METHOD Between 1996 and 2001, FUS was performed in 16 patients for three indications: assessment of renal function (Group 1, n = 12), diagnosis of a cystic mass (Group 2, n = 2), prevention of dystocia (Group 3, n = 2). The anomaly was detected by ultrasound. Urine was aspirated from the two renal pelves and/or bladder, or the cystic mass in the other cases. b2-microglobulin and urinary sodium were assayed and karyotyping was performed at the same time. RESULTS 20 FUS were performed In 4 cases, two samples were taken at an interval of 2 weeks. No complications were observed. Group 1: 9 pregnancies were terminated for potential renal failure (6 posterior urethral valves (PUV), 1 Prune Belly syndrome, 2 cases of recessive polycystic kidney disease (PKD). Three pregnancies were continued for 2 foetuses with normal renal function (1 PUV, 1 ureterocele) and one foetus died with severe renal failure (bilateral hydronephrosis). Group 2: one termination of pregnancy was performed in a case of hepatic cyst with portobiliary dysplasia and a giant bladder diverticulum was operated. Group 3: in both cases, evacuating aspiration allowed normal delivery of one live infant (left polycystic dysplasia), and one neonatal death from megabladder-megacolon syndrome. DISCUSSION The value of FUS is controversial. We usually performed this examination for assessment of renal function. The results of FUS are useful for management decisions when they are in favour of potential impaired renal function. They usually confirmed the ultrasound results that already indicated a poor prognosis and they did not change the decision already based on ultrasound findings in any of our cases. For the diagnosis of cystic masses, after drainage of the mass, FUS facilitated investigation of the urinary tract and adjacent organs. When FUS was performed during labour, it reduced the size of the mass and the abdomen, allowing vaginal delivery with a better ventilatory adaptation of the infant.
