Assessing the external validity and clinical relevance of umbilical doppler resistance index references in daily practice. J Gynecol Obstet Hum Reprod 2024; 53:102720. [PMID: 38160906 DOI: 10.1016/j.jogoh.2023.102720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 12/28/2023] [Accepted: 12/28/2023] [Indexed: 01/03/2024]
Abstract
OBJECTIVE To assess the external validity and clinical relevance of current references for umbilical artery resistance index (UA RI) in daily practice. METHODS Retrospective cross-sectional single center study including all UA RI measurements between 22 and 40 gestational weeks (GW) from distinct patients between 2014 and 2022. Patients with normal pregnancies and normal neonatal outcomes that had an UA RI measurement between 2014 and 2019 were used to calculate reference ranges. The established reference for the 95th centile was compared to two current references. The clinical relevance of the established reference was tested by comparing neonatal outcomes according to the 95th percentile among the consecutive distinct patients between 2020 and 2022. RESULTS Among the 13342 consecutive distinct patients with a singleton pregnancy that had an UA RI measurement between 22 and 40 GW between 2014 and 2022, 5298 patients were included to establish the reference ranges, and 3634 patients to validate these ranges. For each gestational age, the established references were similar to current references. Using the established references, the proportion of patients presenting an UA RI>95th percentile among the patients with normal pregnancies in the validation population was comparable to the proportion when using the two current references. Among the validation population, 268 patients (7.4 %) (95%CI[6.5-8.2]) presented an UA RI ≥ 95th percentile. Of these 268 patients, 67.9% had a SGA newborn (versus 19.2%, p<0.001) and 59% a preterm birth (versus 13.9%, p<0.001). CONCLUSIONS The reference range obtained from daily practice is clinically relevant and similar to current references.

Neu Laxova syndrome and megacystis in the first trimester: Broadening the fetal phenotype. Prenat Diagn 2023; 43:1666-1670. [PMID: 37964427 DOI: 10.1002/pd.6463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 08/11/2023] [Accepted: 08/15/2023] [Indexed: 11/16/2023]
Abstract
Neu Laxova syndrome (NLS) is a rare and lethal congenital disorder characterized by severe intra-uterine growth retardation (IUGR), ichthyosis, abnormal facial features, limb abnormalities with arthrogryposis and a wide spectrum of severe malformations of the central nervous system (CNS). NLS is due to biallelic variants in three genes previously involved in serine-deficiency disorders (PHGDH, PSAT1 and PSPH), extending the phenotypic spectrum of these disorders.

Biochemical Screening for Fetal Trisomy 21: Pathophysiology of Maternal Serum Markers and Involvement of the Placenta. Int J Mol Sci 2023; 24:ijms24087669.

Abstract
It is now well established that maternal serum markers are often abnormal in fetal trisomy 21. Their determination is recommended for prenatal screening and pregnancy follow-up. However, mechanisms leading to abnormal maternal serum levels of such markers are still debated. Our objective was to help clinicians and scientists unravel the pathophysiology of these markers via a review of the main studies published in this field, both in vivo and in vitro, focusing on the six most widely used markers (hCG, its free subunit hCGβ, PAPP-A, AFP, uE3, and inhibin A) as well as cell-free feto-placental DNA. Analysis of the literature shows that mechanisms underlying each marker's regulation are multiple and not necessarily directly linked with the supernumerary chromosome 21. The crucial involvement of the placenta is also highlighted, which could be defective in one or several of its functions (turnover and apoptosis, endocrine production, and feto-maternal exchanges and transfer). These defects were neither constant nor specific for trisomy 21, and might be more or less pronounced, reflecting a high variability in placental immaturity and alteration. This explains why maternal serum markers can lack both specificity and sensitivity, and are thus restricted to screening.

Abstract
OBJECTIVE To determine whether bladder size is associated with an unfavorable neonatal outcome, in the case of first-trimester megacystis. MATERIALS AND METHODS This was a retrospective observational study between 2009 and 2019 in two prenatal diagnosis centers. The inclusion criterion was an enlarged bladder (> 7 mm) diagnosed at the first ultrasound exam between 11 and 13+6 weeks of gestation. The main study endpoint was neonatal outcome based on bladder size. An adverse outcome was defined by the completion of a medical termination of pregnancy, the occurrence of in utero fetal death, or a neonatal death. Neonatal survival was considered as a favorable outcome and was defined by a live birth, with or without normal renal function, and with a normal karyotype. RESULTS Among 75 cases of first-trimester megacystis referred to prenatal diagnosis centers and included, there were 63 (84%) adverse outcomes and 12 (16%) live births. Fetuses with a bladder diameter of less than 12.5 mm may have a favorable outcome, with or without urological problems, with a high sensitivity (83.3%) and specificity (87.3%), area under the ROC curve = 0.93, 95% CI (0.86-0.99), p< 0.001. Fetal autopsy was performed in 52 (82.5%) cases of adverse outcome. In the 12 cases of favorable outcome, pediatric follow-up was normal and non-pathological in 8 (66.7%). CONCLUSION Bladder diameter appears to be a predictive marker for neonatal outcome. Fetuses with smaller megacystis (7-10 mm) have a significantly higher chance of progressing to a favorable outcome. Urethral stenosis and atresia are the main diagnoses made when first-trimester megacystis is observed. Karyotyping is important regardless of bladder diameter.

Abstract
OBJECTIVES To provide up-to-date evidence-based guidelines for the management of smoking cessation during pregnancy. METHODS Systematic review of the international literature. We identified papers published between January 2003 and April 2019 in Cochrane PubMed, and Embase databases with predefined keywords. All reports published in French and English relevant to the areas of focus were included and classified according the level of evidence ranging from 1 (highest) to 4 (lowest). The strength of the recommendations was classified according to the Haute Autorité de santé, France (ranging from A, highest to C, lowest). RESULTS "Counseling", involving globally all kind of non-pharmacological interventions, has a modest benefit on smoking cessation, birth weight and prematurity. Moderate physical activity did not show a significant effect on smoking cessation. The systematic use of feedback by measuring the expired air carbon monoxide concentration do not influence smoking abstinence but it may be used in establishing a therapeutic alliance. The use of self-help interventions and health education are recommended in helping pregnant smokers quit. The prescription of nicotine replacement therapies (NRT) may be offered to any pregnant woman who has failed stopping smoking without medication This prescription can be initiated by the health care professional taking care of the pregnant woman in early pregnancy. There is no scientific evidence to propose the electronic cigarette for smoking cessation to pregnant smokers; it is recommended to provide the same advice and to use methods that have already been evaluated. The use of waterpipe (shisha/narghile) during pregnancy is associated with decreased fetal growth. It is recommended not to use waterpipe during pregnancy. Breastfeeding is possible in smokers, but less often initiated by them. Although its benefit for the child's development is not demonstrated to date, breastfeeding allows the mother to reduce or stop smoking. The risk of postpartum relapse is high (up to 82% at 1 year). The main factors associated with postpartum abstinence are breastfeeding, not having a smoker at home, and having no symptoms of postpartum depression. CONCLUSIONS Smoking during pregnancy concerns more than hundred thousand women and their children per year in France. It is a major public health burden. Health care professionals should be mobilized for reducing or even eradicating it.

Abstract
OBJECTIVES To provide up-to-date evidence-based guidelines for the management of smoking cessation during pregnancy and the post-partum period. STUDY DESIGN A systematic review of the international literature was undertaken between January 2003 and April 2019. MEDLINE, EMBASE databases and the Cochrane library were searched for a range of predefined key words. All relevant reports in English and French were classified according to their level of evidence ranging from 1(highest) to 4(lowest). The strength of each recommendation was classified according to the Haute Autorité de Santé (French National Authority for Health) ranging from A (highest) to C (lowest). RESULTS "Counselling", including all types of non-pharmacological interventions, has a moderate benefit on smoking cessation, birth weight and prematurity. The systematic use of measuring expired air CO concentration does not influence smoking abstinence, however, it may be useful in assessing smoked tobacco exposure prior to and after quitting. The use of self-help therapies and health education are recommended in helping pregnant smokers quit and should be advised by healthcare professionals. Nicotine replacement therapies (NRT) may be prescribed to pregnant women who have failed to stop smoking after trying non-pharmacological interventions. Different modes of delivery and dosages can be used in optimizing their efficacy. Smoking in the postpartum period is essential to consider. The same treatment options as during pregnancy can be used. CONCLUSION Smoking during pregnancy concerns more than a hundred thousand women each year in France resulting in a major public health burden. Healthcare professionals should be mobilised to employ a range of methods to reduce or even eradicate it.

Abstract
OBJECTIVES Prognosis of infants with omphalocele depends on many factors, including associated anomalies. "Small" omphaloceles are believed to have more often WB syndrome, but so far no prenatal criterion has been demonstrated to predict associated anomalies. The aim of this study was to assess the outcomes of omphaloceles with prenatal diagnosis, and to seek for any correlation between the herniated viscera in the first trimester and the risk of associated anomalies. METHODS We conducted a retrospective study at the Necker Enfants Malades Hospital between 2008 and 2018. Pregnancy outcomes and post natal data were collected and compared to the omphalocele content in the first trimester. RESULTS One hundred and ninety-one women with antenatal diagnosis of omphalocele were included. Twenty-eight percent were isolated at birth, 32% had a polymalformative syndrome with chromosomal anomaly, 13% had a polymalformative syndrome without genetic anomaly, 9% had a Wiedemann-Beckwith syndrome, 7% had an association with cardiopathy, 6% had a limb body wall complex, 3% had OEIS complex and one case had a Cantrell pentalogy. The presence of the liver in the omphalocele during the first trimester was a predictive factor of heart disease (85.7% vs 48.6% P=0.01). The presence of bowel in the omphalocele during the first trimester was a predictor of chromosomal abnormalities (69.6% vs 37.2% P<0.001). Omphalocele content in the first trimester was not predictive of Wiedemann-Beckwith syndrome. CONCLUSION Ultrasound analysis in the first trimester of omphalocele content is a valuable clue for prenatal counseling and diagnosis of associated abnormalities.

Abstract
OBJECTIVES Giant omphalocele often represents a major surgical challenge and is reported with high mortality and morbidity rates. The aim of this study was to assess the outcome of neonates with giant omphalocele managed with early operative surgical treatment, and subsequently to identify possible factors that could alter the prognosis. METHODS We reviewed the medical records of 29 consecutive newborns with prenatally diagnosed giant omphalocele. In these cases one of two procedures had been performed: either staged closure after silo, or immediate closure with a synthetic patch. The cases were separated into 2 groups: Isolated giant omphalocele (IO group) and giant omphalocele associated with malformation (NIO group). RESULTS Infants in the IO group had a lower size of the omphalocele (p<0,001), a shorter hospital stay (95 days [45-915] vs. 41.5 days [10-110] p= 0, 02), and a shorter median ventilation length (10 days [1-33] vs. 27, 5 [6-65] p = 0, 05). In the NIO group, 5 cases displayed a significantly more difficult course than the others. They were compared to the remaining cases for prenatal and anatomic features. Four factors associated with greater morbidity were identified: CONCLUSIONS: Isolated omphalocele, even containing the whole liver, has a very good prognosis with early surgical treatment. Without associated anomalies, 95% of giant omphaloceles can be discharged with a median of 41.5 days in hospital. However, associated anomalies (especially cardiopathies) may burden the prognosis and should be both carefully assessed during pregnancy and taken into account in parental information. TYPE OF STUDY Retrospective Study LEVEL OF EVIDENCE: Level I.

Abstract
OBJECTIVE Our study aims to identify risks factors associated with failed trial of scar and to set a predictive score of labour in women with scarred uterus in the Democratic Republic of the Congo. METHODS We conducted a multicenter cross-sectional analytic study of patients with scarred uterus in four maternity units in the Democratic Republic of the Congo (DRC) from 1 January to 31 December 2013. Logistic regression model was used to identify factors associated with failed trial of scar. We set a predictive score based on this model in order to predict trial of scar failure in maternity units in the DRC. ROC curve was used to assess the ability of the set score to identify patients at risk for trial of scar failure. The cut off point for the predictive score was determined on the basis of the Youden-index-based optimal sensitivity and specificity. All the tests in our study were carried out by using a significance threshold of α=0.05. RESULTS Two explanatory factors in trial of scar failure were retained. They were the socio-demographic factor (maternal age) and three obstetric factors (fundal height, fetal presentation and premature rupture of membranes). Predictive score was set to predict trial of scar failure. This score was determined based on four elements: maternal age, evaluation of the gestational sac on admission, fundal height and fetal presentation. The minimum score was set at 4 and the maximum score was set at 16. The threshold value was set at 7. A total score greater than or equal to 7 reflects a risk of trial of scar failure. CONCLUSION We set a predictive score to predict trial of scar failure. This score was determined based on four elements: maternal age, evaluation of the gestational sac on admission, fundal height and fetal presentation. A total score greater than or equal to 7 reflects a risk of trial of scar failure.

Abstract
OBJECTIVES The fetal weight estimation depends largely on the accuracy of abdominal circumference. The quality criteria are standardized to minimize variability and include visualization of the stomach. The objective of this study is to investigate the presence or absence of the stomach on the abdominal circumference for 3 different operators. MATERIAL AND METHODS We conducted re-reading of 204 ultrasound images in the second and third trimester of pregnancy, performed by three operators, at the maternity Port Royal in Paris in 2013. On these images, the presence of the stomach was sought and other quality criteria were verified. RESULTS Among the 204 images, 166 included the stomach (81%). When studying for each of the three operators, there were 79%, 72% and 98% of the stomach into the abdominal circumference, a significant difference between operators (P=0.0029). Regarding the secondary criteria, the quality criteria found most often were the calipers and well placed ellipse (89%). CONCLUSION According to the previous studies, the stomach seems to be a reference to search. Our study shows variability depending on the different operators. If a hierarchy of quality criteria is to be considered, the stomach does not seem to be the first criterion to search.

Abstract
The quantitative assessment of the cervix is crucial for the estimation of pre-term delivery risk and the prediction of the success of labor induction. We conducted a cross-sectional study using shear wave elastography based on the supersonic shear imaging technique. The shear wave speed (SWS) of the lower anterior part of the cervix was quantified over an 8-mm region of interest in 157 pregnant women. Cervical SWS is slightly but significantly reduced in patients diagnosed with pre-term labor and in patients who actually delivered pre-term.

Abstract
Smoking during pregnancy is the leading preventable cause of perinatal morbidity. Half of smokers are weaned during pregnancy resulting in 15% of female smokers at time of delivery. Most often, women spontaneously withdraw at the announcement of pregnancy. Thus, the action of professionals has a modest effect. But this effect is real and should encourage us to take care for patients who smoke. They should feel free with guilty. The spouse must be included in this support to create an enabling environment. Every action has its effectiveness. Nicotine prescription should be reserved for cases where it reduces consumption and keep the medicalized link. It is possible to smoke with a nicotine patch in place; the substitution then reduces the cosumption of each cigarette.

Abstract
Small for gestational age (SGA) is defined by weight (in utero estimated fetal weight or birth weight) below the 10th percentile (professional consensus). Severe SGA is SGA below the third percentile (professional consensus). Fetal growth restriction (FGR) or intra-uterine growth restriction (IUGR) usually correspond with SGA associated with evidence indicating abnormal growth (with or without abnormal uterine and/or umbilical Doppler): arrest of growth or a shift in its rate measured longitudinally (at least two measurements, 3 weeks apart) (professional consensus). More rarely, they may correspond with inadequate growth, with weight near the 10th percentile without being SGA (LE2). Birthweight curves are not appropriate for the identification of SGA at early gestational ages because of the disorders associated with preterm delivery. In utero curves represent physiological growth more reliably (LE2). In diagnostic (or reference) ultrasound, the use of growth curves adjusted for maternal height and weight, parity and fetal sex is recommended (professional consensus). In screening, the use of adjusted curves must be assessed in pilot regions to determine the schedule for their subsequent introduction at national level. This choice is based on evidence of feasibility and the absence of any proven benefits for individualized curves for perinatal health in the general population (professional consensus). Children born with FGR or SGA have a higher risk of minor cognitive deficits, school problems and metabolic syndrome in adulthood. The role of preterm delivery in these complications is linked. The measurement of fundal height remains relevant to screening after 22 weeks of gestation (Grade C). The biometric ultrasound indicators recommended are: head circumference (HC), abdominal circumference (AC) and femur length (FL) (professional consensus). They allow calculation of estimated fetal weight (EFW), which, with AC, is the most relevant indicator for screening. Hadlock's EFW formula with three indicators (HC, AC and FL) should ideally be used (Grade B). The ultrasound report must specify the percentile of the EFW (Grade C). Verification of the date of conception is essential. It is based on the crown-rump length between 11 and 14 weeks of gestation (Grade A). The HC, AC and FL measurements must be related to the appropriate reference curves (professional consensus); those modelled from College Francais d'Echographie Fetale data are recommended because they are multicentere French curves (professional consensus). Whether or not a work-up should be performed and its content depend on the context (gestational age, severity of biometric abnormalities, other ultrasound data, parents' wishes, etc.) (professional consensus). Such a work-up only makes sense if it might modify pregnancy management and, in particular, if it has the potential to reduce perinatal and long-term morbidity and mortality (professional consensus). The use of umbilical artery Doppler velocimetry is associated with better newborn health status in populations at risk, especially in those with FGR (Grade A). This Doppler examination must be the first-line tool for surveillance of fetuses with SGA and FGR (professional consensus). A course of corticosteroids is recommended for women with an FGR fetus, and for whom delivery before 34 weeks of gestation is envisaged (Grade C). Magnesium sulphate should be prescribed for preterm deliveries before 32-33 weeks of gestation (Grade A). The same management should apply for preterm FGR deliveries (Grade C). In cases of FGR, fetal growth must be monitored at intervals of no less than 2 weeks, and ideally 3 weeks (professional consensus). Referral to a Level IIb or III maternity ward must be proposed in cases of EFW <1500g, potential birth before 32-34 weeks of gestation (absent or reversed umbilical end-diastolic flow, abnormal venous Doppler) or a fetal disease associated with any of these (professional consensus). Systematic caesarean deliveries for FGR are not recommended (Grade C). In cases of vaginal delivery, fetal heart rate must be monitored continuously during labour, and any delay before intervention must be faster than in low-risk situations (professional consensus). Regional anaesthesia is preferred in trials of vaginal delivery, as in planned caesareans. Morbidity and mortality are higher in SGA newborns than in normal-weight newborns of the same gestational age (LE3). The risk of neonatal mortality is two to four times higher in SGA newborns than in non-SGA preterm and full-term infants (LE2). Initial management of an SGA newborn includes combatting hypothermia by maintaining the heat chain (survival blanket), ventilation with a pressure-controlled insufflator, if necessary, and close monitoring of capillary blood glucose (professional consensus). Testing for antiphospholipids (anticardiolipin, circulating anticoagulant, anti-beta2-GP1) is recommended in women with previous severe FGR (below third percentile) that led to birth before 34 weeks of gestation (professional consensus). It is recommended that aspirin should be prescribed to women with a history of pre-eclampsia before 34 weeks of gestation, and/or FGR below the fifth percentile with a probable vascular origin (professional consensus). Aspirin must be taken in the evening or at least 8h after awakening (Grade B), before 16 weeks of gestation, at a dose of 100-160mg/day (Grade A).

Abstract
Rupture of a uterine artery pseudo-aneurysm during pregnancy is a rare condition with potential life-threatening complications, and management should take into account the fetal impact of the therapeutic choice. We report the case of a 2cm left uterine artery pseudo-aneurysm revealed by pelvic pain, in a 30-year-old pregnant woman at 26(+0)weeks of gestation (WG). Diagnosis was suspected at ultrasound scan, and confirmed with Magnetic Resonance angiography that showed signs of pre-rupture. An emergency selective embolization attempted in utero allowed the complete exclusion of the aneurysmal sac. The patient gave birth one month later to a girl at 31(+1)WG, initially managed by neonatologists, who is currently in good health.

Abstract
Objective We report an uneventful conservative approach of an advanced abdominal pregnancy discovered at 22 weeks of gestation. Study Design This study is a case report. Results Attempting to extend gestation of an advanced abdominal pregnancy is not a common strategy and is widely questioned. According to the couple's request, the management consisted in continuous hospitalization, regular ultrasound scan, and antenatal corticosteroids. While the woman remained asymptomatic, surgery was planned at 32 weeks, leading to the birth of a preterm child without any long-term complications. Placenta was left in situ with a prophylactic embolization, and its resorption was monitored. Conclusion Depending on multidisciplinary cares and agreement of the parents, when late discovered, prolonging advanced abdominal pregnancy appears to be a reasonable option.

Abstract
OBJECTIVE To determine the efficacy of 16 hour nicotine patches among pregnant smokers, with the dose individually adjusted according to saliva cotinine levels (potential range 10-30 mg/day). DESIGN Randomised, double blind, placebo controlled, parallel group, multicentre trial (Study of Nicotine Patch in Pregnancy, SNIPP) between October 2007 and January 2013. SETTING 23 maternity wards in France. PARTICIPANTS 476 pregnant smokers aged more than 18 years and between 12 and 20 weeks' gestation, who smoked at least five cigarettes a day. After exclusions, 402 women were randomised: 203 to nicotine patches and 199 to placebo patches. Data were available on 192 live births in each group. INTERVENTIONS Nicotine and identical placebo patches were administered from quit day up to the time of delivery. Doses were adjusted to saliva cotinine levels when smoking to yield a substitution rate of 100%. Participants were assessed monthly and received behavioural smoking cessation support. MAIN OUTCOME MEASURES The primary outcomes were complete abstinence (self report confirmed by carbon monoxide level in expired air ≤ 8 ppm) from quit date to delivery, and birth weight. The secondary outcomes were point prevalence of abstinence, time to lapse (a few puffs) or relapse, and delivery and birth characteristics. All data were analysed on an intention to treat basis. RESULTS Complete abstinence was achieved by 5.5% (n=11) of women in the nicotine patch group and 5.1% (n=10) in the placebo patch group (odds ratio 1.08, 95% confidence interval 0.45 to 2.60). The median time to the first cigarette smoked after target quit day was 15 days in both groups (interquartile range 13-18 in the nicotine patch group, 13-20 in the placebo patch group). The point prevalence abstinence ranged from 8% to 12.5% in the nicotine patch group and 8% to 9.5% in the placebo patch group without statistically significant differences. The nicotine substitution rate did not differ from 100%, and the self reported median compliance rate was 85% (interquartile range 56-99%) in the nicotine patch group and 83% (56-95%) in the placebo patch group, assessed at 1016 visits. The mean birth weight was 3065 g (SE 44 g) in the nicotine patch group and 3015 g (SE 44 g) in the placebo patch group (P=0.41). Diastolic blood pressure was significantly higher in the nicotine patch group than in the placebo patch group. The frequency of serious adverse events was similar between the groups, although more non-serious adverse reactions, mainly of skin, occurred in the nicotine patch group. CONCLUSION The nicotine patch did not increase either smoking cessation rates or birth weights despite adjustment of nicotine dose to match levels attained when smoking, and higher than usual doses. TRIAL REGISTRATION ClinicalTrials.gov NCT00507975.

Abstract
The medical training concerning childbirth for young obstetricians involves performing real deliveries, under supervision. This medical procedure becomes more complicated when instrumented deliveries requiring the use of forceps or suction cups become necessary. For this reason, the use of a versatile, configurable childbirth simulator, taking into account different anatomical and pathological cases, would provide an important benefit in the training of obstetricians, and improve medical procedures. The production of this type of simulator should be generally based on a computerized birth simulation, enabling the computation of the reproductive organs deformation of the parturient woman and fetal interactions as well as the calculation of efforts produced during the second stage of labor. In this paper, we present a geometrical and biomechanical modeling of the main parturient's organs involved in the birth process, interacting with the fetus. Instead of searching for absolute precision, we search to find a good compromise between accuracy and model complexity. At this stage, to verify the correctness of our hypothesis, we use finite element analysis because of its reliability, precision and stability. Moreover, our study improves the previous work carried out on childbirth simulators because: (a) our childbirth model takes into account all the major organs involved in birth process, thus potentially enabling different childbirth scenarios; (b) fetal head is not treated as a rigid body and its motion is computed by taking into account realistic boundary conditions, i.e. we do not impose a pre-computed fetal trajectory; (c) we take into account the cyclic uterine contractions as well as voluntary efforts produced by the muscles of the abdomen; (d) a slight pressure is added inside the abdomen, representing the residual muscle tone. The next stage of our work will concern the optimization of our numerical resolution approach to obtain interactive time simulation, enabling it to be coupled to our haptic device.

Abstract
Fetal choroid plexus tumors are uncommon. The prognosis is widely variable and depends on the histological findings: papilloma or carcinoma. We report a case of prenatal diagnosis of choroid plexus mass detected by ultrasound at 33 weeks of gestation. Prenatal (T1, T2, T2* and diffusion weighted sequences) magnetic resonance imaging (MRI) was used to rule out a hematoma. Follow-up examination by ultrasound and MRI revealed a significant increase in the volume of the mass, suggesting a diagnosis of malignant tumor. A healthy neonate was delivered by Cesarean section at 38 weeks of gestation. Full surgical excision of the tumor was performed at 20 days after delivery and histological analysis revealed a papilloma.

Abstract
OBJECTIVE The variability of nuchal translucency thickness (NT) measurements in the first trimester appears to be associated in part with caliper placement. Methods for obtaining semi-automated adjusted measurements (SAAMs) can provide several NT values (maximum, minimum, mean and median) automatically within a manually set frame in the zone of interest. This study sought to assess the feasibility and reproducibility of these SAAM-NTs. METHODS Three readers, two experts and one less experienced, examined archive images of 160 patients and obtained SAAM-NTs from them, on two separate occasions. The intra- and interobserver reproducibility were assessed by calculating the intraclass correlation coefficients (ICCs) for maximum, mean and median SAAM-NTs, and Bland-Altman plots were constructed. RESULTS SAAM-NTs were technically feasible for all 160 images. The range of ICCs for intraobserver reproducibility was 0.76-0.93 for mean SAAM-NT, 0.76-0.95 for median SAAM-NT and 0.74-0.95 for maximum SAAM-NT. Interobserver ICCs were 0.85, 0.85 and 0.84 for mean SAAM-NT, median SAAM-NT and maximum SAAM-NT, respectively. There were no significant differences for intra- and interobserver reproducibility of median, mean and maximum SAAM-NTs. CONCLUSIONS SAAM-NT is feasible with a high level of intra- and interobserver reproducibility. This easy-to-use method has the potential to simplify screening during the first trimester. It should be evaluated further and compared with the manual measurement method.

Abstract
In this report, the authors describe 4 recent cases of posterior giant dural venous sinus ectasia in neonates diagnosed during pregnancy and encountered at 3 different institutions. Posterior giant venous sinus ectasia was diagnosed in 4 patients using antenatal ultrasonography and confirmed in 2 patients using prenatal MR imaging and in 3 patients using postnatal MR angiography. In 2 children angiography was performed at the age of 6 months. The pregnancy was terminated in 1 case, and the fetus underwent an autopsy. The 3 children who were born presented with various degree of cardiac insufficiency and were admitted to the intensive care unit after birth. Signs of increased intracranial pressure were present immediately after birth, including a bulging fontanel. No endovascular treatment was used in these cases. Surgery was performed in 2 cases as an attempt to alleviate increased intracranial pressure symptoms, without any real benefit. A slow venous flow in the ectasia was shown by ultrasonography in the case in which the pregnancy was terminated. Angiography or MR angiography did not show an obvious arteriovenous malformation in any of the cases, but an arteriovenous fistula secondary or contributing to the formation of the venous ectasia is one of the physiopathological hypotheses of the cause of this condition. Interestingly, spontaneous progressive thrombosis and regression of the intravascular component of the venous sinus ectasia was observed in all cases. The clinical outcome was acceptable in 1 child (who had a moderate handicap after the surgery) and good for the other 2 children (who had normal neurological development). Stratified thrombi of different ages are found in these giant venous ectasias and develop within the leaves of the dura close to the confluence of the major posterior venous sinuses. Therefore, it appears that the formation of a progressive thrombosis represents the normal evolution of these giant dural venous sinus ectasias, which explains the favorable outcome in some cases without specific surgical treatment, except for resuscitation techniques.

Abstract
OBJECTIVE To characterize tracheal fluid flow during fetal breathing movements by Doppler ultrasound. STUDY DESIGN To use pulsed Doppler to measure flow velocity during inspiration and expiration in a cross-sectional study of 15 normal fetuses and determine the correlation, if any, between flow velocity and gestational age. RESULTS Cyclic respiratory profiles - both regular and irregular - were observed. Intratracheal flow velocity was very elevated during inspiration, ranging from 10 to 80 cm/s and from 5 to 20 cm/s during expiration. CONCLUSION This technique enables the noninvasive semiquantitative evaluation of fetal breathing movements. This Doppler application opens the field for future studies to characterize the extent of pulmonary hypoplasia.

Abstract
OBJECTIVES To compare the diagnostic value of fundal height and sonographically measured fetal abdominal circumference in the prediction of high and low birth weight in routine practice between 37 and 41 weeks' gestation. METHODS Data were obtained from a multicenter study of 19 415 women in France and Belgium. In this study we included 7138 low-risk women from that population who underwent fundal height measurements no more than 8 days before delivery (Population A). We also included another 1689 women with both fundal height measurements and fetal ultrasound measurements obtained no more than 8 days before delivery (Population B). Population A was used to calculate the parameters of equations for estimating fetal weight according to fundal height alone (EFW(FH)) or fundal height in combination with other clinical indicators (EFW(FH+)). The ultrasound fetal weight estimation was based on fetal abdominal circumference (EFW(AC)) using Campbell and Wilkins' equation. The correlation between the estimated fetal weight calculated using each of the formulae and the birth weight was then evaluated in Population B, and the diagnostic value of each of the methods for predicting birth weight <or=2500 g or >or=4000 g was also compared. RESULTS EFW(AC) was better correlated with birth weight than was either EFW(FH) or EFW(FH+). With specificity set at 95%, the sensitivity of EFW(AC) in screening for neonates weighing <or=2500 g was significantly higher than that of EFW(FH) (50.7% vs. 41.2%, P < 0.05) or EFW(FH+) (50.7% vs. 40.4%, P < 0.05). Similarly, its sensitivity for predicting a birth weight of >or=4000 g was significantly higher than that of EFW(FH) (54.0% vs. 37.1%, P < 0.05) or EFW(FH+) (54.0% vs. 45.1%, P < 0.05). CONCLUSIONS Sonographic measurement of fetal abdominal circumference predicts high and low birth weight better than does clinical examination based on fundal height in routine practice between 37 and 41 weeks' gestation.

Abstract
We describe a fetal intracerebral hemorrhage associated with familial thrombophilia. Intraventricular and intraparenchymal hemorrhage of the left cerebral hemisphere was diagnosed at 22 weeks of gestation. Neuropathologic examination demonstrated a large germinal zone hemorrhage and ischemic changes secondary to bleeding. The fetus manifested a heterozygous Leiden mutation of the factor V gene, and a heterozygous F76L mutation of the protein C gene. The literature indicates that the coexistence of genetic risk factors of thrombophilia and fetal intracerebral hemorrhage is rare, except in the context of pregnancy-related complications. The utility of laboratory screening is discussed.

Abstract
INTRODUCTION The human papillomavirus (HPV) is the most common cause of sexually transmitted infections worldwide, and its prevalence is highest among young women aged 17-25 years. It is the principal risk factor for cervical cancer. Systematic vaccination of adolescent girls should significantly reduce the incidence of this disease and its related mortality. AIM One of the objectives of the Enjeux study, a population-based survey, was to identify the place of young girls within the French health care system to help assess the optimal conditions for implementing anti-HPV vaccination. METHODS Data came from 5354 interviews of women aged 18-70 years, 320 of whom provided information about daughters aged 11-14 years and 406 about daughters aged 15-17 years. Among the latter, 318 were also interviewed and 294 completed a self-administered questionnaire. RESULTS The results showed that sexual activity was reported by approximately one third of the girls aged 15-17 years. At-risk behaviors in these girls included insufficient contraception (only 51% use condoms). Data on the medical management of the population of 11-17 year-old girls indicate that they have access to - and are integrated into - the health care system, with frequent medical visits. They see the general practitioner (GP) most frequently, followed by the school doctor. The frequency of general practice visits is similar in both age groups; more than 50% of the girls visit their GP more than twice a year. Vaccination is a frequent reason for these visits; gynecologic reasons are less frequent. CONCLUSION The results of this survey underline the central place of the GP in the health management of young girls aged 11 to 17 years.
