Screening for Chlamydia trachomatis, Neisseria gonorrhoeae, and Mycoplasma genitalium should it be integrated into routine pregnancy care in French young pregnant women?

Chlamydia trachomatis, Neisseria gonorrhoeae, and Mycoplasma genitalium screening during pregnancy is not performed routinely in France. We conducted the first prospective study in 1004 women attending for routine antenatal care to determine the prevalence and risk factors for these bacterial infections. The overall prevalence of C. trachomatis, N. gonorrhoeae, and M. genitalium infections was 2.5%, 0%, and 0.8%, respectively. In patients aged 18-24 years, the prevalence increased to 7.9% for C. trachomatis and to 2.4% for M. genitalium. C. trachomatis infection was associated with age ≤24 years or being single or having more than 5 sexual partners in a lifetime. M. genitalium infection was more frequent in patients aged ≤24 years or who had a history of abortion or their first sexual intercourse after 20 years of age. The high prevalence of C. trachomatis in pregnant women aged ≤24 years, mostly asymptomatic, suggests that systematic screening could be beneficial.

[Bilateral uterine rupture of an unscarred gravid uterus before labor]. / Rupture utérine bilatérale sur utérus gravide non cicatriciel en dehors du travail.

We report a case of bilateral spontaneous uterine rupture of an unscarred uterus occured in a primigravida at 32 weeks to take care in our department after in utero transfert. Uterine rupture occurs mainly on scarred uterus during labor. This is an unfrequent but serious complication involving fetal-maternal prognosis in the absence of immediate care. We are conducting a review about spontaneous uterine rupture of unscarred uterus, before and during labor.

[Predictive value of combined fibronectin and ultrasound cervical assessment in twin pregnancies]. / Valeur prédictive du couplage de la fibronectine à l'échographie du col chez les grossesses gémellaires.

OBJECTIVE: To test a sequential test with fetal fibronectin detection after ultrasound measurement of cervical length to predict preterm delivery in twin pregnancies with preterm labor. PATIENTS AND METHODS: Descriptive retrospective study on 50 women with twin pregnancy hospitalised for preterm labor between 24 and 34 weeks and 6 days of gestation. The primary outcomes were preterm delivery before 34 or 37 weeks of gestation or within 7 or 14 days. Selective use of fibronectin after cervical length measurement has been tested, with a sequential test considered positive if cervical length was less than or equal to 15mm or if cervical length was between 16 and 30mm with fetal fibronectin positive. RESULTS: The sensitivity/specificity/and positive and negative predictive values of fetal fibronectin positive were 71%, 64%, 26%, et 93% for delivery within 7 days; those of cervical length less than or equal to 20mm were 89%, 51%, 31%, et 95% for delivery before 34 weeks and 6 days. The efficiency of the sequential test seemed better than each test and than for singleton pregnancies keeping an excellent negative predictive value: sensitivity of 75%, specificity of 63%, positive predictive value of 26% and negative predictive value of 93.5% for prediction of preterm delivery within 14 days. The use of this sequential test could have decreased half of fibronectin tests. DISCUSSION AND CONCLUSION: A sequential test with selective use of fetal fibronectin detection in twin pregnancies selected by ultrasound measurement of cervical length appears to be effective for predicting preterm birth if preterm labor, avoiding half of fibronectin tests.

[Interest of lactate micro-dosage in scalp and umbilical cord in cases of abnormal fetal heart rate during labor. Prospective study on 162 patients]. / Place du microdosage des lactates au scalp et au cordon devant des anomalies du rythme cardiaque fœtal pendant le travail. Étude prospective sur 162 patientes.

OBJECTIVE: To compare the interest of lactate microanalysis with pH measurement (Gold Standard procedure) in cord blood and fetal scalp blood samples for the assessment of abnormal fetal heart rate (FHR) during labour. STUDY DESIGN: A prospective observational study conducted from July 1st 2007 till March 31st 2008 on 162 patients with abnormal FHR during labour. RESULTS: Sampling failure for scalp lactate was less than 1 % compared to a failure of 10.5 % for scalp pH (P<0.001). There was a good correlation between pH and lactates in fetal scalp blood samples and in cord blood samples, between lactate in the last fetal scalp sample and in cord blood. When there was umbilical acidosis (pH≤7.15 or lactate≥5mmol/L), Apgar score at 5 minutes was significantly lower than when there was no acidosis (4.66±3.59 versus 8.35±2.73 for pH ; 6.6±3.77 versus 8.45±2.58 for lactate). The specificity of the lactate in the umbilical cord artery (≥5 mmol/laws) was 76.4 % for predicting an Apgar score at 5 minutes less than 7 ; 79.7 % for predicting the need for immediate neonatal care ; 77.3 % for predicting an hospital stay in neonatal unit. These figures were generally worse but close to those found for a threshold value of umbilical artery pH≤7.15. CONCLUSION: The values of lactate in cord blood and fetal scalp blood samples were comparable to pH values (Gold standard procedure). This method is easy to perform and is an attractive alternative to pH for monitoring fetal asphyxia. It is our opinion that the combination of the two methods is of interest.

[Confined placental mosaicisms a priori from meiotic origin: analysis of 10 cases]. / Anomalies chromosomiques limitées au placenta a priori d'origine méiotique : à propos de dix cas.

This retrospective monocenter study focused on confined placental mosaicisms a priori from meiotic origin (i.e. non-mosaic type 3 confined placental mosaicisms). From a series of 14,967 chorionic villus samplings performed in our Fetal Medicine Center, 10 non-mosaic type 3 confined placental mosaicisms were identified. These abnormalities only involved chromosomes 15, 16 or 22. Pregnancies complicated by these confined placental mosaicisms were associated with prematurity and neonatal hypotrophy. Thus, when a confined placental mosaicism is suspected, this retrospective study highlighted the need to characterize the type of confined placental mosaicism to prevent the probable intra-uterine growth retardation and to adapt the obstetrical monitoring if necessary.

[Sequential use of cervical length measurement before fetal fibronectin detection to predict spontaneous preterm delivery in women with preterm labor]. / Utilisation séquentielle de la longueur échographique du col utérin puis de la détection de la fibronectine foetale pour prédire une prématurité spontanée en cas de menace d'accouchement prématuré.

OBJECTIVE: To test a sequential test with fetal fibronectin detection after ultrasound measurement of cervical length to predict preterm delivery in women with preterm labor. STUDY DESIGN: Descriptive retrospective study on 111 women hospitalised for preterm labor between 24 and 34 weeks and six days of gestation. The primary outcomes were preterm delivery before 34 or 37 weeks of gestation or within seven or 14 days. Selective use of fetal fibronectin detection after cervical length measurement has been tested, with a sequential test considered positive if cervical length was inferior or equal to 15 mm or if cervical length was between 16 and 30 mm with fetal fibronectin positive. RESULTS: The sensitivity/specificity/and positive and negative predictive values of fetal fibronectin positive were 75, 71, 17 and 97% for delivery within 14 days; those of cervical length inferior or equal to 20mm were 75, 52, 21, and 92% for delivery before 34 weeks. The efficiency of the sequential test was similar with excellent negative predictive value: sensitivity/specificity/and positive and negative predictive values of 75, 63, 26, and 93.5% for prediction of preterm delivery before 34 entire weeks. The use of this sequential test could have avoided 37% of fibronectin tests. CONCLUSION: A sequential test with selective use of fetal fibronectin detection in population selected by ultrasound measurement of cervical length appears to be as effective than fetal fibronectin detection or cervical length alone for predicting preterm birth, if preterm labor, avoiding more than one third of fibronectin tests.

First-trimester prenatal diagnosis performed on pregnant women with fetal ultrasound abnormalities: the reliability of interphase fluorescence in situ hybridization (FISH) on mesenchymal core for the main aneuploidies.

OBJECTIVES: To examine the reliability of interphase FISH analysis of the main aneuploidies performed on mesenchymal core when prenatal diagnosis was performed on pregnant women with first-trimester fetal abnormalities on ultrasound. STUDY DESIGN: 386 first-trimester prenatal examinations were investigated from chorionic villus samplings for increased nuchal translucencies or other fetal ultrasound abnormalities. Interphase fluorescence in situ hybridization (FISH) for the main aneuploidies (trisomies 13, 18, 21 and gonosomal aneuploidies) was performed on the mesenchymal core of villi. Molecular cytogenetic results were always complemented by conventional cytogenetic results on long-term cultured villi (LTC-villi). Short-term cultured villi (STC-villi) preparations were retrospectively performed only when a chromosomal abnormality was observed with interphase FISH and/or LTC-villi. RESULTS: 88 chromosomal abnormalities (88/386=22.8% of first-trimester diagnoses) which could discuss subsequent abortions were observed after LTC-villi preparations. All cases possibly detectable by interphase FISH were detected. Thus, 85 aneuploidies (85/386=22.0% of first-trimester diagnoses; 85/88=96.6% of chromosomal abnormalities) were detected by interphase FISH, allowing early abortion by curettage before week 14 amenorrhea. No discrepancy occurred between interphase FISH and LTC-villi results for the aneuploidies studied. Three false-negative results (3/386=0.77% of first-trimester diagnoses; 3/88=3.41% of chromosomal abnormalities) were observed with STC-villi. CONCLUSION: We observed a high rate of false-negative results on cytotrophoblast cells. Conversely, interphase FISH of the main aneuploidies on the mesenchymal core provided rapid and reliable results, and therefore should be preferred to STC-villi in first-trimester prenatal diagnosis performed on pregnant women with fetal abnormalities on ultrasound.

Pain experience during chorionic villus sampling and amniocentesis: a preliminary study.

OBJECTIVE: To investigate the maternal perception of pain before and after amniocentesis (AC) or transabdominal chorionic villus sampling (TA-CVS). STUDY DESIGN: Three hundred women were divided into groups of 100 participants destined to undergo three different fetal sampling procedures: amniocentesis (group 1), transabdominal chorionic villus sampling (CVS) with a 19 gauge Blache needle (group 2) and transabdominal CVS with a 20 gauge needle (group 3). The visual analog scale (VAS) was used to quantify the patient's pre-sampling expected pain level and the real pain level was measured immediately after the sampling procedure. The factors liable to influence the VAS score after the sampling procedure were studied by single and multivariate analysis and concerned either the sampling procedure or patient demographic data. RESULTS: The VAS scores obtained before the procedure were not significantly different for the three sampling groups. When performed with a 19 gauge Blache needle TA-CVS is significantly more painful than the other sampling procedures (p=0.0002): VAS score of 3.62 (group 2), 2.49 (group 3) and 2.68 (group 1) for CVS with 20 gauge needle and amniocentesis. Multivariate analysis identified a group of patients for which the perception of pain induced by sampling was higher compared to the other patients: nulliparous patients, having undergone 19 gauge Blache needle CVS, with a high pre-sampling VAS score. CONCLUSION: Transabdominal chorionic villus sampling with a 19 gauge Blache needle seems to be the most painful sampling procedure. We question the need to use a 19 gauge needle as acceptable results are obtained with a 20 gauge needle.

[Perinatal prognosis of pregnancies complicated by placental chronic intervillitis]. / Pronostic périnatal des grossesses compliquées d'intervillites chroniques placentaires.

UNLABELLED: SUBJECT. Massive Chronic Intervillositis is an infrequent inflammation lesion of the placenta, characterized by lymphohistiocytic intervillous infiltration, associated with fibrinoid deposition. The purpose of this study was to evaluate the perinatal outcome of pregnancies complicated by such lesions. MATERIAL AND METHODS: We conducted a descriptive retrospective multicentric analysis of a series of pregnancies for which placenta or products of abortion were analyzed between January 1995 and September 2005, at the University Hospital of Bordeaux. After re-examining the histology slides, we performed a semi-quantitative graduation of the cell infiltration and fibrinoid deposition. RESULTS: Twenty-five women were included (one twin-pregnancy and two histologic recurrences). We found three spontaneous abortions before 22 weeks, four intrauterine fetal deaths and three neonatals deaths. Seven of eight elective inductions pregnancies, were performed for intrauterine growth restriction less than 2.5 percentile. The rate of pregnancy loss was 55% and the perinatal mortality was 29%. 77% of fetuses are small for gestational age. Three mothers were pre-eclamptic. 21% of the fetuses had a congenital malformation. Only 32% of the fetuses were alive one week after birth. Histologically, 25% were associated with lesions of Villitis of Unknown Etiology. 77% of the cell infiltration was grade 3 and seemed to be correlated with severe growth restriction. We describe 3 cases of antenatal diagnosis of Chronic Intervillositis, realised after immunofixation on chorionic villous sampling. CONCLUSION: Massive Chronic Intervillositis is a recurrent lesion with a poor prognosis complicated by spontaneous abortion, intrauterine growth restriction and perinatal fetal death. Currently, there is no treatment. Chorionic villous sampling in severe growth restriction might be useful in order to obtain at the same time the fetal karyotype and an histological probe of the placenta.

Nonoperative management of spontaneous splenic rupture in infectious mononucleosis: the role for emerging diagnostic and treatment modalities.

Infectious mononucleosis (IM) is a self-limiting lymphoproliferative disorder affecting teenagers and young adults. Splenomegaly is a common manifestation of IM and results in a compromised organ that may rarely rupture spontaneously, with significant morbidity and mortality. The IM spleen should be protected from even minor trauma. Although traditional management of spontaneous splenic rupture in IM has been splenectomy, the role of nonoperative management is evolving. The advent of endovascular interventional modalities has augmented the physician's armamentarium in managing these patients nonoperatively. We report a case of spontaneous splenic rupture in a patient with IM managed conservatively with the aid of splenic angiography. The option of arteriography, with or without embolization, should be considered in the management of all patients with spontaneous splenic rupture in the setting of IM.

Differential expression of the nm23 genes in the developing human trophoblast.

NDP kinases are the non-specific enzymes which catalyse the synthesis of the NTPs through a transfer reaction using ATP as phosphoryl donor. In addition to their enzymatic activity, they display other not yet explained functions related to cell growth, differentiation and apoptosis, embryonic development, tumour progression and metastasis. In this study, the expression patterns of the three highly related NDP kinases A, B and C isoforms were investigated in the developing human trophoblast. Both NDP kinase A and B were found to be primarily present in the villous and extravillous cytotrophoblasts, while NDP kinase C was found almost exclusively in the syncytiotrophoblast layer. This suggests that NDP kinase A and B could be a marker for the mononuclear stage of differentiation of villous trophoblasts, while NDP kinase C could be a marker of the syncytiotrophoblast layer.

[Importance of thrombocytopenia for the management of HELLP syndrome: a report of 104 cases]. / Importance de la thrombopénie dans la prise en charge du HELLP syndrome: à propos de 104 cas.

OBJECTIVES: To evaluate the importance of thrombocytopenia in the management of HELLP syndrome (hemolysis, elevated liver enzymes, low platelet count). MATERIALS AND METHODS: This retrospective study included all patients with HELLP syndrome treated in the three departments of the Pellegrin Maternity Hospital in Bordeaux, between January 1993 and December 2001. One hundred and four patients were included and were divided into two groups according to the severity of thrombopenia: group 1 (platelet count<50000/mm(3)) and group 2 (50000

Pregnancy outcome and prognosis in fetuses with increased first-trimester nuchal translucency.

OBJECTIVE: One of the concerns of prenatal diagnosis is to find sensitive markers to screen for chromosome abnormalities, such as serum assays or nuchal translucency (NT). This study reports our experience with NT measurement during the first trimester of pregnancy. MATERIALS: The study was performed prospectively on 252 fetuses with either NT > or =3 mm or cystic hygroma. RESULTS: We observed 50 abnormal karyotypes, i.e. 19.8%. The incidence of chromosome abnormalities increased with increasing maternal age and increasing NT thickness. For the 202 fetuses with normal karyotypes, outcome was unfavourable in 32 cases: 23 elective terminations of pregnancy, 8 spontaneous abortions and 1 neonatal death. Outcome was favourable in 141 cases. Twenty-nine pregnancies were lost to follow-up. CONCLUSION: Measurement of NT at 12 weeks' gestation seems to be a good marker for chromosome abnormalities. When the karyotype is normal, the pregnancy outcome remains correlated with the degree of NT thickness. The finding of NT >3 mm between 10 and 14 weeks' gestation dictates rigorous ultrasound monitoring and caution when predicting pregnancy outcome.

IVF following impossible or failed surgical reversal of tubal sterilization.

Microsurgical re-anastomosis or IVF offer ways of reversing previous tubal sterilization. This retrospective study analysed 56 attempts of IVF in 37 couples after impossible or failed surgical sterilization reversal. Efficacy of IVF in this group (TL) was compared with that of a tubal pathology control group (TP) at all stages of IVF (stimulation, fertilization and implantation). Depending on patient age, significantly fewer oocytes were produced after ovarian stimulation in the TL group than in the control (TP) group (P = 0.023 for all TL patients; P = 0.02 when patients aged >38 years were excluded). The total number of embryos available for transfer was significantly lower in the TL group (P = 0.0042), but this was age-related, since when women aged >38 years were excluded there was no significant difference between the two groups. The ongoing pregnancy rate was similar in both groups, the probability of ongoing pregnancy appearing to depend on patient age rather than on previous fertility.

[Maternal transport to the Bordeaux University Hospital: a retrospective study of 263 cases (1996-1998)]. / Le transfert des enfants in utero au Centre Hospitalier Universitaire de Bordeaux : analyse rétrospective de 263 cas (1996-1998).

OBJECTIVES: To describe a population of high risk pregnancies transported to a regional perinatal care centre (level III) and to analyze the advantages and limitations of the organization of this perinatal care network. METHODS: Retrospective study of 263 patients transported to the University Hospital of Bordeaux between September 1996 and September 1998. RESULTS: Maternal transport mainly came from the Gironde department (53%) and from level I care hospitals (66%). The rate of multiple pregnancies was 17%. Principal indications were preterm labor with or without rupture of fetal membranes (52%) and preeclampsia with or without intrauterine growth restriction (28%). The rate of returns to the referring care centre was 2%. The mean term at delivery was 32 WA. Forty-one percent of patients delivered within 24 hours of transport. The rate of caesarean sections was 55%. There were 303 live births. The mean duration of hospitalization of the neonates was 28 days. The rate of perinatal mortality was 6.2%. Among the 96 pregnancies beyond 32 WA, 17 (6.5%) could have been transported to some level IIb care hospitals, nearby the patient's residence, without changing maternal and neonatal prognosis. Neonatal mortality was not significantly different for maternel transport (18%) or neonatal transport (14%) in the group of premature infants born prior to 31 WA in our study. CONCLUSION: Our organization is currently trying to improve transport management (non-emergency situations, collaboration of level II care hospitals) and to increase the rate of returns to the referring care centres.

[Urinary incontinence in elderly women]. / L'incontinence urinaire de la femme âgée.

Urinary incontinence in elderly women, though due to several factors, is not inevitable; case-by-case management is often effective.
