[Diagnosis of trisomy 21: nuchal translucency and/or serum markers?].

OBJECTIVES: To compare alternative methods of antenatal screening for Down's syndrome (nuchal translucency measurement and second trimester maternal serum screening) in a low-risk population and to evaluate the consequences of a sequential estimation of risk. METHODS: In a consecutive series of 4308 women aged less than 38 with a singleton pregnancy, we examined the detection rate of nuchal translucency (NT) measurement at 10-14 weeks and maternal serum screening (MSS) by human chorionic gonadotropin and alpha-feto-protein at 14-18 weeks. Women with a NT measurement = 3 mm and women with a MSS derived risk = 1/250 were recommended to have an amniocentesis. A second trimester detailed ultrasound scan was also performed in all women. The outcome of all pregnancies was entered in a computerized database and the detection rate and false-positive rate of different screening strategies were analysed. RESULTS: Of the 4308 pregnancies that were followed (mean maternal age 30.1 years), there were 12 cases of Down's syndrome (0.28%), all detected prenatally. Seven of twelve cases had a NT measurement above 3 mm (58%), and 6 out of ten cases with available MSS had a calculated risk = 1/250 (60%). Four of the five cases with NT measurement below 3 mm were detected by subsequent MSS. At a threshold giving 5% of positive tests, the sensitivity of NT screening and MSS were 75% and 60%, respectively. DISCUSSION AND CONCLUSION: Sequential screening for Down's syndrome by nuchal translucency and second trimester biochemistry is effective and appears to increase the detection rate compared to the use of any single test. However, this strategy is likely to raise the false-positive rate and the interpretation of MSS derived risk should be combined to the first trimester NT measurement.

Screening for Down syndrome using first-trimester ultrasound and second-trimester maternal serum markers in a low-risk population: a prospective longitudinal study.

OBJECTIVES: To compare nuchal translucency and second-trimester maternal serum measurements as alternative methods of antenatal screening for Down syndrome in a low-risk population and to evaluate the consequence of combining the results in the estimation of risk. DESIGN: In a consecutive series of 4130 women aged less than 38 years with a singleton pregnancy, we examined both the detection rate of Down syndrome by nuchal translucency measurement at 10-14 weeks and maternal serum screening by human chorionic gonadotrophin and alpha-fetoprotein at 14-18 weeks. Women with a nuchal translucency measurement of > or = 3 mm and women with a maternal serum screening-derived risk > or = 1/250 were recommended to have amniocentesis. A second-trimester detailed ultrasound scan was also performed in all women. The outcome of all pregnancies was recorded prospectively and the detection rate and false-positive rate of different screening strategies were retrospectively analyzed. RESULTS: Out of the 4130 pregnancies that were followed (mean maternal age, 30.1 years), 12 cases of Down syndrome were observed (0.28%), all detected prenatally. Seven of 12 cases had a nuchal translucency measurement of > or = 3 mm (58%), and six out of 10 cases with available maternal serum screening had a calculated risk of > or = 1/250 (60%). Four of the five Down syndrome cases with a nuchal translucency measurement of < 3 mm were detected by subsequent maternal serum screening. At a threshold giving 5% of positive tests, the sensitivity of nuchal translucency, maternal serum screening and combined risk screening were 75%, 60% and 90%, respectively. CONCLUSIONS: In screening for Down syndrome, an approach which combines the results from first-trimester nuchal translucency and second-trimester biochemistry is effective and increases the detection rate compared to the use of any single test. However, this strategy is likely to raise the false-positive rate and the interpretation of maternal serum screening-derived risk should be combined with the first-trimester nuchal translucency measurement.

Bipolar coagulation of the umbilical cord in complicated monochorionic twin pregnancy.

OBJECTIVES: In monochorionic twin pregnancy in which one twin is a nonviable fetus, selective feticide may be considered. We aimed to occlude the umbilical cord with a bipolar forceps for doing so. STUDY DESIGN: This was a multicenter experience in 10 consecutive patients either with twin-to-twin transfusion syndrome and one fetus affected by a condition not compatible with normal extrauterine life or with acardiac twinning. RESULTS: There were no intraoperative problems, and the mean procedure time was 17.5 minutes. The flow was stopped in all 10 cases. Two cases were complicated by rupture of the fetal membranes within 2 days, and the pregnancies were terminated. The other 8 pregnancies resulted in the live birth of a healthy baby. The mean interval between procedure and birth was 15.1 weeks (range, 7-20 weeks). In one patient emergency cesarean delivery for abruptio placentae was done at 26 weeks, 7 weeks after the procedure. The other 7 patients were delivered beyond the 36th week of gestation. All 8 children are alive and well, with a mean follow-up of at least 1 year. CONCLUSION: Bipolar coagulation is a safe, effective, and simple procedure for cord coagulation that is feasible through a single port and can be performed solely under ultrasonographic guidance.

Outcome of premature infants delivered after prolonged premature rupture of membranes before 25 weeks of gestation.

OBJECTIVE: To identify factors influencing the outcome of premature infants delivered after prolonged premature rupture of membranes before 25 weeks' gestation. DESIGN AND POPULATION: All premature infants with gestational age <34 weeks, either inborn or outborn, with history of rupture of membranes before 25 weeks' gestation, admitted to our NICU between January 1992 and July 1997, were eligible for this retrospective study. Collected information included birth weight, gestational age at rupture of membranes and at delivery, duration between rupture of membranes and delivery (latency period), severity of oligohydramnios, pre- and post-natal managements, and follow-up of survivors. RESULTS: A total of 28 neonates fulfilled the inclusion criteria. Despite new strategies of ventilation and optimal management, the overall mortality rate was 43% (12/28). Nonsurvivors were significantly less mature at rupture of membranes, and had severe oligohydramnios (anamnios). We also noted less antenatal corticosteroids and antibiotic therapy in this group. Nine of eleven infants (82%) following rupture of membranes before 22 weeks' gestation died shortly after birth. The two remaining infants developed severe bronchopulmonary dysplasia. Nine deaths occurred in thirteen cases (69%) of anamnios. The major death causes were refractory respiratory failure and neurologic complications. Half of all survivors (8/16) developed bronchopulmonary dysplasia. CONCLUSION: The outcome of premature infants following prolonged premature rupture of membranes before 25 weeks' gestation is influenced by gestational age at rupture, severity of oligohydramnios, and antenatal antibiotics and corticosteroids. Neonates with rupture of membranes before 22 weeks have a very low chance of survival at the present time.

Diagnosis of small-for-gestational-age fetuses between 24 and 32 weeks, based on standard sonographic measurements.

OBJECTIVE: To create and validate a formula using sonographic biometry measurements for the optimal diagnosis of small-for-gestational-age (SGA) fetuses between 24 and 32 weeks of gestation. METHODS: A logistic model using gestational age, femur diaphysis length, abdominal and head circumferences to diagnose SGA was set up in a first group of 64 fetuses born between 24 and 32 weeks (group I). A Receiver Operating Characteristic (ROC) curve was drawn. Our model was compared with standard single ultrasound measurements or combined into an estimated fetal weight (EFW) formula. An external validation was carried out on a second group of 183 fetuses (group II) from another maternity unit (ROC curve and comparisons). RESULTS: The area under the ROC curve was 0.91 in group I and 0.93 in group II. Using a 0.5 cut off point for our model yielded a sensitivity of 76% and specificity of 91% for group I. This model is more specific than most other measurement methods with a similar sensitivity. Using the same cut off point (0.5) in Group II, our model was more specific (98%) but less sensitive (66%) when compared with single ultrasound measurements and EFW formulae. By varying the cut off point, we were able to demonstrate that, for a similar sensitivity, our model had a higher specificity than single ultrasound measurements and had similar specificity to EFW formulae. CONCLUSION: The logistic model we set up was able to calculate an SGA risk score between 24 and 32 weeks of gestation in a population at high risk for elective delivery. The cut off point with a view to diagnosis can vary and makes it possible to give greater importance to the sensitivity or specificity depending on the clinical context.

Maternal-fetal staphylococcal infections: a series report.

The objective of this paper is to study the characteristics of maternal-fetal staphyloccocal infection. A retrospective study among 1,582 infants admitted consecutively to our neonatal intensive care unit was carried out from January 1995 through September 1998. The antenatal history, and the clinical and bacteriological findings and outcome of the infants fulfilling maternal-fetal staphyloccocal infection were analysed. Among 122 (7.7%) maternal-fetal infection, 11 cases (8.9%) of congenital staphyloccal infections were diagnosed in 9 premature and 2 full-term babies. Antenatal invasive procedures were noted in 6 occasions (56%). All the 11 infants developed respiratory and hemodynamic failure. Staphylococcus aureus was the most common organism encountered in maternal bacteriologic data (9/11, 82%) as well as on peripheral sites (9/11, 82%) and in blood cultures (7/11, 64%) performed in the infants. There was one case of methicillin-resistant Staphylococcus aureus. The outcome was favorable for 9 infants. Two very preterm neonates died within the first 72 hours of life. Mother-to-infant transmission of Staphylococcus should be suspected whenever invasive procedures are performed during pregnancy and in the presence of severe neonatal distress associated with an inflammatory response. Prompt and adapted antibiotic therapy allows a favourable outcome.

The relationships between antenatal management, the cause of delivery and neonatal outcome in a large cohort of very preterm singleton infants.

OBJECTIVE: To determine whether the cause of very preterm delivery influences neonatal outcome. DESIGN: A cohort study of 685 consecutive singletons born before 33 weeks of gestation. METHODS: Causes of birth and perinatal outcome variables were correlated for statistical significance by uni- and multi-variate analyses. RESULTS: Intrauterine growth retardation or pre-eclampsia were associated with a higher rate of respiratory distress syndrome compared with prolonged rupture of membranes, after controlling for gestational age, antenatal corticosteroid therapy, antenatal antibiotic administration, mode of delivery and origin (inborn or outborn) (adjusted OR 3.12; 95% CI 1.55-6.28). The prevalence of grade 3-4 intraventricular haemorrhage or cystic periventricular leukomalacia was 25% in newborn babies born after intrauterine infection or prolonged rupture of membranes. Among infants born after intrauterine growth retardation/pre-eclampsia, the rate of severe intraventricular haemorrhage was 3.2% and the rate of periventricular leukomalacia was 0.9%. Compared with intrauterine infection and after controlling for potential confounding covariates, intrauterine growth retardation/pre-eclampsia was associated with a lower rate of periventricular leukomalacia (adjusted OR 0.08; 95% CI 0.02-0.41). In the same multiple logistic regression model, antenatal corticosteroid administration was associated with a lower incidence of periventricular leukomalacia (adjusted OR 0.36; 95% CI 0.16-0.79). CONCLUSIONS: The cause of very preterm delivery has an important influence on neonatal outcome.

Multiple courses of antenatal glucocorticoid treatment and fetal outcome.

Thanks to the US National Institutes of Health Consensus Conference, the odds of antenatal use of glucocorticoids for preventing severe neonatal complications of premature delivery have significantly increased these last years. The belief that neonatal benefits last up to 7 days after the first course and administration of further courses is safe has led many obstetricians to prescribe multiple antenatal glucocorticoid courses. Whether multiple courses offer an advantage over a single course has not been demonstrated. In contrast, there are accumulating evidence suggesting that this practice may have short and long-term side effects. The potential benefits and side effects of multiple antenatal courses of glucocorticoids, extrapolated from experimental data and observational studies, are detailed in this review. Until the results of ongoing randomized trials with long term follow-up are available, the practice of giving multiple courses of glucocorticoids to women should be considered with the greatest caution.

[Cervical cerclage with buried prosthetic band: technique, indications and results in a series of 28 pregnancies].

OBJECTIVES: We performed a retrospective study to evaluate the results of a new approach to cervical cerclage using a prosthetic band. MATERIALS AND METHODS: Twenty-four patients were recruited over an 8-year period between 1991 and 1999. All had a history of at least two late abortions and/or preterm delivery and a failed attempt with McDonald or Hervet cerclage. We used a cervical cerclage technique with prosthetic band inspired from the Shirodkar technique but which has been simplified and quite easy to reproduce. The technique consists in placing a prosthetic band around the internal os under the vaginal mucosa at the vesicovaginal reflection level. Outcome of pregnancy before and after inserting the prosthetic band was compared. RESULTS: Outcome of 28 pregnancies after cerclage were assessed (4 patients had two successive pregnancies with the same cerclage left in place). 82% of the children were liveborn after cerclage versus 21.7% before cerclage. 53.3% of the patients delivered at term after cerclage versus 2.8% before cerclage. We had 7.1% late miscarriages after cerclasge versus 65.2% before. There were no surgical complications. 22 of the 23 liveborn children were delivered by cesarean section. Conclusion. These results show that the cervical prosthesis is a solution of these patients with an obstetric history of cervical incompetence with failure of classical techniques.

[Value of amnioculture for choosing antibiotic treatment for premature rupture of membranes before 34 weeks gestation].

OBJECTIVE: This study attempts to answer the following question: is systematic amniocentesis an efficient tool for adjusting an antibiotic treatment in case of preterm premature rupture of membranes? METHODS: Retrospective study of 76 cases of preterm premature rupture of membranes that occurred between January 1994 and February 1997 in a French teaching hospital. RESULTS: Amniocentesis was impossible for 28 patients (Group I). In this group there was a 46% rate of neonatal sepsis (n=13). Amniocentesis was successful in 48 patients. 24 delivered within 48 hours after amniocentesis (Group IIa). In this group there was a 29% rate of neonatal sepsis (n=7), and amniotic fluid culture was positive in 33% of the cases. 24 delivered beyond 48 hours after amniocentesis (Group IIb). In this group there was a 21% rate of neonatal sepsis (n=5) and amniotic fluid culture was positive in 12.5% of the cases. Group I and IIa had a high risk of neonatal sepsis and could not benefit from amniocentesis culture results. CONCLUSION: Group IIa and IIb cannot be distinguished a priori, therefore systematic amniocentesis can only have a restricted impact on the management of antibiotic therapy. Even in the case of a negative amniotic fluid culture, antibiotic therapy is mandatory. If a systematic amniocentesis policy is used, one hundred amniocentesis have to be performed in order to adapt six antibiotic therapies. In the group with the highest risk of neonatal sepsis (severe oligohydramnios), amniocentesis cannot be performed. A policy of systematic amniocentesis restricted to the cases that are not delivered within the first 48 hours could be evaluated in a prospective randomized trial. Such a policy could help in deciding whether to stop, adapt, or continue the antibiotic therapy, or to induce the delivery in case of an asymptomatic chorioamniotitis.

[Regionalization of perinatal care and in utero referrals].

Further improvement in perinatal morbidity and mortality figures implies in utero referral so high risk infants, particularly very early maturity infants, can be managed immediately in specialized centers. The success of such referrals depends directly on the coherence of the regional perinatal health care network. It has been demonstrated that the chances of survival and of sequelae-free survival are greater for very premature infants born in a center with a neonatal intensive care unit. The situation in France leaves room for improvement. Only 15% of the infants born before 33 months gestation and with birth weight under 1500 g are born in level III maternity wards equipped with a neonatal intensive care unit. The goal is 80%. We have tried to analyze the reasons behind this situation and propose ways to better organize perinatal health care.

Antenatal glucocorticoid treatment and cystic periventricular leukomalacia in very premature infants.

BACKGROUND: Antenatal glucocorticoid therapy decreases the incidence of several complications among very premature infants. However, its effect on the occurrence of cystic periventricular leukomalacia, a major cause of cerebral palsy, remains unknown. METHODS: We retrospectively analyzed a cohort of 883 live-born infants, with gestational ages ranging from 24 to 31 weeks, who were born between January 1993 and December 1996 at three perinatal centers in the Paris area. The mothers of 361 infants had received betamethasone before delivery, the mothers of 165 infants had received dexamethasone before delivery, and the mothers of 357 infants did not receive glucocorticoids. We compared the rates of cystic periventricular leukomalacia among the three groups of infants in bivariate and multivariate analyses after adjustment for confounding factors. RESULTS: The rate of cystic periventricular leukomalacia was 4.4 percent among the infants whose mothers had received betamethasone, 11.0 percent among the infants whose mothers had received dexamethasone, and 8.4 percent among the infants whose mothers had not received a glucocorticoid. After adjustment for gestational age, the mode of delivery, and the presence or absence of chorioamnionitis, prolonged interval between the rupture of membranes and delivery (>24 hours), preeclampsia, and the use of tocolytic drugs, antenatal exposure to betamethasone was associated with a lower risk of cystic periventricular leukomalacia than was either the absence of glucocorticoid therapy (adjusted odds ratio, 0.5; 95 percent confidence interval, 0.2 to 0.9) or exposure to dexamethasone (adjusted odds ratio, 0.3; 95 percent confidence interval, 0.1 to 0.7). The adjusted odds ratio for the group of infants whose mothers had received dexamethasone as compared with the group of infants whose mothers had not received a glucocorticoid was 1.5 (95 percent confidence interval, 0.8 to 2.9). CONCLUSIONS: Antenatal exposure to betamethasone but not dexamethasone is associated with a decreased risk of cystic periventricular leukomalacia among very premature infants.

Neonatal outcome in severe preeclampsia at 24 to 36 weeks' gestation: does the HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome matter?

OBJECTIVE: Our purpose was to compare neonatal outcome after preterm delivery of infants whose gestation was complicated by the HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome, partial HELLP syndrome, or severe preeclampsia. STUDY DESIGN: We reviewed the maternal and neonatal charts from 269 consecutive pregnancies complicated by the HELLP syndrome or severe preeclampsia managed at our perinatal center. The HELLP syndrome was defined by previously published laboratory criteria. Viable pregnancies were divided into 3 groups: HELLP syndrome, partial HELLP syndrome (at least 1, but not all 3, features of the HELLP syndrome), and severe preeclampsia (no features of the HELLP syndrome). Results were compared by means of chi2 analysis and Student t test where appropriate. Logistic regression was used to evaluate outcome variables at different gestational ages. RESULTS: There were no significant differences in complications among the 3 groups at each gestational age. There was, as expected, a significant decrease in morbidity and mortality rates with advanced gestational age. CONCLUSIONS: In severe preeclampsia, neonatal morbidity and death are related to gestational age rather than to the presence or absence of the HELLP syndrome. Whether expectant management is safe for women with the HELLP syndrome requires further study.

Herpes simplex virus encephalitis in pregnancy.

BACKGROUND: Although polymerase chain reaction (PCR) can detect herpes simplex virus (HSV) in the cerebrospinal fluid (CSF), HSV encephalitis remains a significant cause of neurologic impairment in pregnant women. Assessment of fetal contamination also remains a problem. CASES: We report two cases in which HSV encephalitis initially was not suspected and led to significant maternal neurologic impairment. In both cases, HSV PCR of CSF confirmed the diagnosis. In one case, fetal serum HSV PCR excluded fetal contamination. CONCLUSION: As soon as encephalitis in pregnancy is suspected, a combination of acyclovir and penicillin is recommended because the potential benefits far outweigh the risks. Using the HSV PCR, HSV infection in the fetus can be diagnosed.

Implication of apolipoprotein E and the L-arginine-nitric oxide system in preeclampsia.

OBJECTIVE: During pregnancy, Apolipoprotein (Apo) E is synthesized in the placenta to facilitate the uptake of maternal lipoproteins. Preeclampsia is associated with an abnormal lipid profile. Apo E levels may affect the production of nitric oxide. We investigated whether Apo E variations could be related to the high lipid levels and nitric oxide secretion in preeclamptic women. METHODS: Blood samples from 15 normotensive women and 12 mild and 23 severe cases of preeclampsia were assayed for standard lipid profile, Apo E, and nitrate. Urine samples were analyzed for nitrate and cyclic GMP. RESULTS: In women with mild preeclampsia, the triglyceride concentration was significantly higher (p < 0.05) than in normotensive women (3.30 +/- 1.38 versus 2.31 +/- 0.92 g/L) and associated with a higher (p < 0.01) triglyceride/Apo E ratio (0.71; range = 0.40-1.70). In women with severe preeclampsia, the triglyceride/Apo E ratio was similar to normotensive women [0.39 (range = 0.18-1.19) versus 0.41 (range = 0.18-0.79)] associated with a normal triglyceride level and a twofold higher serum nitrate level [36 (range = 1-63 mumol/L) versus 14 (range = 1-37 mumol/L)]. CONCLUSION: The triglyceride/Apo E ratio is significantly higher in mild preeclampsia. In the severe form, this ratio is similar to that of normotensive pregnant women, probably due to a better uptake of triglyceride. Moreover, in the severe form, it is associated with a twofold normal serum nitrate level. Thus, Apo E and the nitric oxide status may be implicated in preeclampsia.

[Clinical importance of fetal pulse oximetry. I. Methodological evaluation. Multicenter study. French Study Group on Oximetry of Fetal Pulse].

OBJECTIVE: To evaluate the feasibility of intrapartum fetal pulse oximetry, the distribution of fetal oxygen saturation values, and the relation with the neonatal outcome in a population with an abnormal fetal heart rate (FHR). STUDY DESIGN: A prospective multicenter observational study, from June 1994 to November 1995. Fetal oxygen saturation was continuously recorded using a Nellcor N-400 fetal pulse oximeter in case of abnormal FHR during labor. Simultaneous readings of fetal oxygen saturation and of fetal blood analysis (FBA) were obtained at inclusion and before birth. Feasibility, adverse effects, distribution of fetal oxygen saturation values and relation with neonatal outcome were assessed. RESULTS: 74 patients were included. From 172 attempted sensor placements, the procedure was impossible in three cases and fetal oxygen saturation values were obtained in 164 cases (95.3%). Physicians considered sensor placement an easier task than FBA attempt (easy in 87.5% vs 78.9% for FBA, p = 0.03). The mean reliable signal time (+/- SD) was 64.7 +/- 32% during the first stage. There were no serious adverse effects in the study population. The mean fetal oxygen saturation during the first stage of labor was 42.2 +/- 8.0% (10th-90th centile range: 30-53%). Fetal oxygen saturation was significantly correlated with scalp pH (r = 0.29; p = 0.01) but not with neonatal umbilical artery pH or gas values. There was a significant association between a low fetal oxygen saturation (< 30%) and a poor neonatal condition. CONCLUSION: The feasibility of fetal pulse oximetry is satisfactory in clinical practice. It is easy to use and provides a fair rate of recorded values, even in a population with suspicion of fetal distress. A low fetal oxygen saturation is significantly associated with an abnormal neonatal outcome.

[Clinical importance of fetal pulse oximetry. II. Comparative predictive values of oximetry and scalp pH. Multicenter study].

OBJECTIVE: To compare the predictive value of intrapartum fetal pulse oximetry to that of fetal blood analysis for an abnormal neonatal outcome in case of abnormal fetal heart rate (FHR). STUDY DESIGN: A prospective multicenter observational study, from June 1994 to November 1995. Fetal oxygen saturation was continuously recorded using a Nellcor N-400 fetal pulse oximeter in case of abnormal FHR during labor. Simultaneous readings of fetal oxygen saturation and fetal blood analysis obtained before birth, i.e. either at full dilatation, or before cesarean section when indicated, were compared with the neonatal status. The criteria for an abnormal neonatal outcome were 1) an umbilical arterial blood pH < or = 7.15 and 2) a combined variable including: 5 min. Apgar score < or = 7, umbilical arterial pH < or = 7.15, secondary respiratory distress, transfer in a neonatal care unit, or neonatal death. RESULTS: At a 7.20 threshold for fetal scalp pH, and 30% for fetal oxygen saturation (i.e. the tenth centile in the study population), the predictive value of fetal pulse oximetry was similar to that of fetal blood analysis for an arterial umbilical pH < or = 7.15, and for an abnormal neonatal outcome (positive predictive value 56% vs 55%, negative predictive value 81% vs 82%, sensitivity 29% vs 35%, and specificity 93% vs 91% respectively). The receiver operating curve showed similar performance of either technique for cut-off values < or = 7.20 for fetal blood pH and < or = 30% for fetal oxygen saturation, whereas fetal pulse oximetry became superior at higher thresholds. CONCLUSION: The predictive value of intrapartum fetal pulse oximetry can be favorably compared with that of fetal blood analysis. Randomized controlled management trials can now be performed to assess potential clinical benefits of this new tool.
