Balloon catheter vs oxytocin alone for induction of labor in women with a previous cesarean section: A randomized controlled trial.

INTRODUCTION: The aim of this study was to compare the efficacy and maternal-neonatal morbidity between balloon catheter and oxytocin for induction of labor in women with a previous cesarean section and an unfavorable cervix. MATERIAL AND METHODS: This open-label randomized controlled trial took place in seven French hospitals. Inclusion criteria were medical indication for labor induction in pregnant women, ≥37 weeks, with lower segment cesarean section, Bishop score ≤4, no pre-labor rupture of membranes, singleton fetus in cephalic presentation. Women were allocated randomly to induction with a 50-mL balloon catheter for 12 hours or a low-dose oxytocin infusion. Primary outcome was the rate of vaginal birth. Secondary outcomes were maternal and neonatal complications. RESULTS: The study enrolled 204 women from 26 December 2010 to 31 December 2013: 101 were allocated to receive balloon catheter and 103 to oxytocin. Vaginal birth rate was 50% (n = 51) in the balloon catheter group vs 37% (n = 38) in the oxytocin group (P = 0.050). Maternal and neonatal morbidity did not differ between balloon catheter and oxytocin groups: two uterine dehiscences vs one, one vs four maternal infections, five vs two hemorrhages and 11 vs five neonatal transfers, respectively. Heterogeneity of treatment effect for vaginal delivery was observed across initial Bishop scores. Balloon catheter was more effective for low values of bishop score. CONCLUSIONS: Balloon catheter tended to be associated with a higher probability of vaginal delivery as compared with low-dose intravenous oxytocin when used for induction of labor in women with a previous cesarean section and low Bishop score at induction.

Association Between Planned Cesarean Delivery and Neonatal Mortality and Morbidity in Twin Pregnancies.

OBJECTIVE: To evaluate the association between the planned mode of delivery and neonatal mortality and morbidity in an unselected population of women with twin pregnancies. METHODS: The JUmeaux MODe d'Accouchement (JUMODA) study was a national prospective population-based cohort study. All women with twin pregnancies and their neonates born at or after 32 weeks of gestation with a cephalic first twin were recruited in 176 maternity units in France from February 2014 to March 2015. The primary outcome was a composite of intrapartum mortality and neonatal mortality and morbidity. Comparisons were performed according to the planned mode of delivery, planned cesarean or planned vaginal delivery. The primary analysis to control for potential indication bias used propensity score matching. Subgroup analyses were conducted, one according to gestational age at delivery and one after exclusion of high-risk pregnancies. RESULTS: Among 5,915 women enrolled in the study, 1,454 (24.6%) had planned cesarean and 4,461 (75.4%) planned vaginal deliveries, of whom 3,583 (80.3%) delivered both twins vaginally. In the overall population, composite neonatal mortality and morbidity was increased in the planned cesarean compared with the planned vaginal delivery group (5.2% compared with 2.2%; odds ratio [OR] 2.38, 95% confidence interval [CI] 1.86-3.05). After matching, neonates born after planned cesarean compared with planned vaginal delivery had higher composite neonatal mortality and morbidity rates (5.3% compared with 3.0%; OR 1.85, 95% confidence interval 1.29-2.67). Differences in composite mortality and morbidity rates applied to neonates born before but not after 37 weeks of gestation. Multivariate and subgroup analyses after exclusion of high-risk pregnancies found similar trends. CONCLUSION: Planned vaginal delivery for twin pregnancies with a cephalic first twin at or after 32 weeks of gestation was associated with low composite neonatal mortality and morbidity. Moreover, planned cesarean compared with planned vaginal delivery before 37 weeks of gestation might be associated with increased composite neonatal mortality and morbidity.

Exploring "psychic transparency" during pregnancy: a mixed-methods approach.

BACKGROUND: Psychic transparency is described as a psychic crisis occurring during pregnancy. The objective was to test if it was clinically detectable. METHODS: Seven primiparous and seven nulliparous subjects were recorded during 5 min of spontaneous speech about their dreams. 25 raters from five groups (psychoanalysts, psychiatrists, general practitioners, pregnant women and medical students) listened to the audiotapes. They were asked to rate the probability of the women being pregnant or not. Their ability to discriminate the primiparous women was tested. The probability of being identified correctly or not was calculated for each woman. A qualitative analysis of the speech samples was performed. RESULTS: No group of rater was able to correctly classify pregnant and non-pregnant women. However, the raters' choices were not completely random. The wish to be pregnant or to have a baby could be linked to a primiparous classification whereas job priorities could be linked to a nulliparous classification. CONCLUSIONS: It was not possible to detect Psychic transparency in this study. The wish for a child might be easier to identify. In addition, the raters' choices seemed to be connected to social representations of motherhood.

Perianal Crohn's disease results in fewer pregnancies but is not exacerbated by vaginal delivery.

BACKGROUND: Despite a high prevalence of Crohn's disease in women of childbearing age, disease-related factors that may impact fertility and perianal Crohn's disease after delivery remain unclear. METHODS: Self-administered questionnaires related to childbirth were completed by women with Crohn's disease referred to a single gastroenterology unit. A survival analysis was performed for statistical purposes. RESULTS: A total of 184 patients were assessed, including 63 nulliparous women. The cumulative probabilities of having a child were 30%, 51% and 72% at the ages of 25, 30 and 35 years, respectively. Women with colonic disease, prior abdominal surgery and perianal disease were less likely to experience childbirth. After a median follow-up of 165 weeks post-delivery, the cumulative probabilities of fistulizing perianal Crohn's disease occurrence were 8%, 12% and 21% at 1, 2 and 5 years following childbirth, respectively. Contrary to a prior history of perianal Crohn's disease and colonic location, mode of delivery was not associated with perianal fistula. An episiotomy in the group of women with prior anal lesions did not result in a higher rate of fistula recurrence. CONCLUSION: Perianal Crohn's disease is associated with fewer pregnancies, however perianal fistulas were less affected by obstetric events than their own natural history.

Propranolol during pregnancy for large chorioangioma.

Large chorioangiomas are frequently associated with adverse perinatal outcome. Its treatment remains invasive and controversial. Infantile hemangiomas which have numerous similarities with chorioangiomas are now usually treated with propranolol. This drug has been extensively used with a good tolerance during pregnancy in other indications. We report the first use of propranolol with the aim of limiting the increase in chorioangioma volume and avoiding the associated complications. The observed inhibition of the growth of the chorioangioma after introduction of propranolol argues for further evaluation of this treatment in this indication.

Scoring system avoids Chlamydia trachomatis overscreening in women seeking surgical abortions.

OBJECTIVE: To develop and validate a predictive score to avoid unnecessary screening and prophylactic antibiotic use in abortion clinics by identifying a group of women who are at very low risk for Chlamydia trachomatis (CT) infection. METHODS: This population-based retrospective study includes 1000 women who underwent surgical abortion between January and September 2010. The main outcome measure was the rate of CT infection among women seeking an induced abortion according to sociodemographic and clinical data. The score was developed by using two-thirds of the data set as the derivation sample to identify the strongest predictors of CT. A receiver operating characteristic curve established cutoffs and applied the score to the remaining one-third (validation sample). RESULTS: The rate of CT infection was 6.7%. Three criteria were independently associated with CT: gestation more than 10 weeks (adjusted odds ratio [aOR], 1.96; 95% confidence interval [95% CI], 1.06-3.64), not using contraception (aOR, 2.70; 95% CI, 1.41-5.16), and having 0 or 1 child (aOR, 3.46; 95% CI, 1.34-8.93). The CT score was based on these 3 criteria. The low-risk group was derived from values of the score (probability of CT, 1.3% [95% CI, 0-3.0]). Application of these criteria to the validation data set confirmed the diagnostic accuracy of the score (probability of CT, 0%). Sensitivity was 100% and specificity was 26.9% for the score in the validation data set. When applied to the validation data set, the score avoided 25.4% of CT tests and screened 100% of CT-infected women before surgical abortion. CONCLUSIONS: This easy-to-calculate score may prove useful for avoiding CT test in 25% of patients seeking surgical abortion.

Paracetamol, aspirin, and indomethacin induce endocrine disturbances in the human fetal testis capable of interfering with testicular descent.

CONTEXT: Masculinization depends on the fetal testis. Exposure of the human fetus during pregnancy to paracetamol and/or to other mild analgesics is associated with an increased risk of cryptorchidism. OBJECTIVE: We aimed to determine whether mild analgesics disrupted the morphology and endocrine function of the human testis. DESIGN: We used an in vitro system based on the culture of human fetal testes exposed or not to paracetamol, its metabolite N-(4-hydroxyphenyl)-arachidonoylethanolamide (AM404), aspirin, indomethacin, and ketoconazole at 10(-4) to 10(-7) M. SETTING: The study was conducted at the University of Rennes I. PATIENTS/PARTICIPANTS: Human fetal testes were from pregnant women after induced abortion, between 7 and 12 weeks of gestation (GW). MAIN OUTCOME MEASURES: Testosterone (RIA), anti-Müllerian hormone (ELISA), insulin-like factor 3 (RIA), and prostaglandin (PG) D2 and PGE2 (ELISA) were assayed in the medium. Testicular cells were counted using histology and image analysis. The possible nuclear receptor-mediated activities of the analgesics were investigated using reporter cell lines expressing estrogen, androgen, and peroxisome proliferator-activated γ receptors. RESULTS: Indomethacin and aspirin stimulated testosterone production, particularly by the younger testes (8-9 GW vs 10-12 GW). Paracetamol, AM404, and ketoconazole decreased insulin-like factor 3 levels. Aspirin stimulated whereas ketoconazole inhibited AMH production. PGE2 levels were inhibited by paracetamol and aspirin in the 7 to 12 GW testes and by indomethacin but only in 7 to 9.86 GW testes. The inhibitory trends seen for PGD2 were not statistically significant. CONCLUSIONS: Analgesics at concentrations relevant to human exposure cause endocrine disturbances in the fetal testis. We suggest that the fetal human testis displays slight critical age windows for sensitivity to direct exposure to aspirin, indomethacin, and paracetamol. The analgesic-induced inhibition of INSL3 may be the mechanism by which analgesics increase the risk of cryptorchidism. Greater caution is required concerning consumption of analgesics during pregnancy.

Caesarean section at term: the relationship between neonatal respiratory morbidity and microviscosity in amniotic fluid.

OBJECTIVES: The incidence of neonatal respiratory morbidity following an elective caesarean section is 2-3 times higher than after a vaginal delivery. The microviscosity of surfactant phospholipids, as measured with fluorescence polarisation, is linked with the functional characteristics of fetal surfactant and thus fetal lung maturity, but so far this point has received little attention in newborns at term. The aim of the study is to evaluate the correlation between neonatal respiratory morbidity and amniotic microviscosity (Fluorescence Polarisation Index) in women undergoing caesarean section after 37 weeks' gestation. STUDY DESIGN: The files of 136 women who had undergone amniotic microviscosity studies during elective caesarean deliveries at term were anonymised. Amniotic fluid immaturity (AFI) was defined as a Fluorescence Polarisation Index higher than 0.335. RESULTS: Respiratory morbidity was observed in 10 babies (7.3%) and was independently associated with AFI (OR: 6.11 [95% CI, 1.20-31.1] with p=0.029) and maternal body mass index (OR: 1.12 [95% CI, 1.02-1.22] with p=0.019). Gestational age at the time of caesarean delivery was inversely associated with AFI (odds ratio, 0.46 [95% confidence interval, 0.29-0.71], p<0.001), especially before 39 weeks, and female gender was associated with an increased risk (odds ratio, 3.29 [95% confidence interval, 1.48-7.31], p=0.004). CONCLUSIONS: AFI assessed by amniotic microviscosity was significantly associated with respiratory morbidity and independently correlated with shorter gestational age especially before 39 weeks. This finding provides a physiological rationale for recommending delaying elective caesarean section delivery until 39 weeks of gestation to decrease the risk for respiratory morbidity.

Screening for Chlamydia trachomatis using self-collected vaginal swabs at a public pregnancy termination clinic in France: results of a screen-and-treat policy.

OBJECTIVE: To assess the prevalence of Chlamydia trachomatis (CT) infection and the risk factors for CT infection among women presenting for abortion at a clinic in France. METHODS: Women seeking surgically induced abortions were systematically screened by PCR on self-collected vaginal swabs between January 1, 2010, and September 30, 2010. CT-positive women were treated with oral azithromycin (1 g) before the surgical procedure. RESULTS: Of the 978 women included in the study, 66 were CT positive. The prevalence was 6.7% (95% confidence intervals [CI] 5.1%-8.3%). The risk factors for CT infection were the following: age <30 years (Odds ratio [OR]: 2.0 [95% CI: 1.2-3.5]), a relationship status of single (OR: 2.2 [95% CI: 1.2-4.0]), having 0 or 1 child (OR: 5.2 [95% CI: 2.0-13.0]), not using contraception (OR: 2.4 [95% CI: 1.4-4.1]), and completing 11 weeks or more of gestation (OR: 2.1 [95% CI: 1.3-3.6]). Multiple logistic regression indicated that 4 factors--having 0 or 1 child, a single relationship status, no contraceptive use, and a gestation of 11 weeks or more--were independently associated with CT infection. The rate of postabortion infection among all patients was 0.4% (4/978). CONCLUSIONS: These results reveal a high prevalence (6.7%) of CT-positive patients among French women seeking induced abortions. Because it is not common practice to screen the general population for CT, screening before induced abortions seems relevant. A cost-effectiveness study is required to evaluate this screen-and-treat policy.

Maternal immune response and neonatal seroprotection from a single dose of a monovalent nonadjuvanted 2009 influenza A(H1N1) vaccine: a single-group trial.

BACKGROUND: Pregnant women and infants who get influenza are at increased risk for severe illness. OBJECTIVE: To evaluate the immunogenicity and transplacental antibody transfer of 2009 pandemic influenza A(H1N1) vaccine administered during pregnancy. DESIGN: Prospective, multicenter, single-group clinical trial. (ClinicalTrials.gov registration number: NCT01024400) SETTING: Five level-3 perinatal centers in France. PATIENTS: 107 pregnant women between 22(0/7) and 32(0/7) weeks of gestation. INTERVENTION: An intramuscular dose of a nonadjuvanted H1N1 vaccine that contained 15 mcg of hemagglutinin. MEASUREMENTS: Proportion of women with an influenza antibody titer of 1:40 or greater at days 21 and 42 after vaccination, delivery, and 3 months after delivery. Seroconversion rate, fold increase in the geometric mean titer 21 days after vaccination, and proportion of neonates with an antibody titer of 1:40 or greater at birth were also assessed. RESULTS: At baseline, 19% of the women had an antibody titer of 1:40 or greater. At day 21, 98% of the women had an antibody titer of 1:40 or greater, the seroconversion rate was 93%, and the fold increase in geometric mean titer was 67.4. At day 42, delivery, and 3 months after delivery, 98%, 92%, and 90% of the women, respectively, had an antibody titer of 1:40 or greater. Ninety-five percent of the cord serum samples obtained from 88 neonates showed an antibody titer of 1:40 or greater. The median neonate-mother antibody titer ratio was 1.4. LIMITATIONS: Only healthy pregnant women were selected. Data on hemagglutination inhibition antibody titers of infants were reported only at birth. CONCLUSION: A single dose of a nonadjuvanted influenza A(H1N1) vaccine with 15 mcg of hemagglutinin triggered a strong immune response in pregnant women and a high rate of neonatal seroprotection.

Terminal 6.9 Mb deletion of chromosome 15q, associated with a structurally abnormal X chromosome in a patient with congenital diaphragmatic hernia and heart defect.

We report the case of a female patient exhibiting multiple congenital malformations including diaphragmatic hernia and heart defect. Cytogenetic studies (including karyotype, FISH and array-CGH) showed a de novo terminal deletion (6.9 Mb) on chromosome 15 in association with a recombinant X chromosome bearing a 9-Mb Xp duplication and a 46-Mb Xq deletion distal to XIST. The recombinant X chromosome was caused by a maternal inv(X)(p22.31q22.3). The X chromosome inactivation pattern was skewed in the patient suggesting a possible inactivation of the recombinant X chromosome. Considering these results, the phenotype was linked to the de novo terminal 15q deletion. These results strengthen the assumption that array-CGH should be applied to each fetus/newborn with multiple congenital malformations.

Perinatal morbidity and mortality in twin pregnancies with dichorionic placentas following assisted reproductive techniques or ovarian induction alone: a comparative study.

OBJECTIVE: To compare maternal and perinatal outcome in non-spontaneously and spontaneously conceived dichorionic twin pregnancies. STUDY DESIGN: We report a retrospective study of all 350 twin pregnancies delivered ≥22 weeks of gestation between January 1, 2001 and December 31, 2005 in a tertiary maternity unit. We compared maternal outcome, perinatal morbidity and neonatal mortality between spontaneous and non-spontaneous dichorionic twin pregnancies, with a subgroup analysis separating pregnancies following assisted reproduction technology (ART group) from those following ovarian induction alone (OI group). Generalized linear model and multivariate analysis were performed. RESULTS: The proportion of primiparous women and the mean maternal age were higher in the non-spontaneously conceived dichorionic twin pregnancy group as expected (70.2% vs. 38.2%, p<0.001 and 32.1 ± 3.8 vs. 30.7 ± 4.6 years, p<0.01). Multivariate analysis, adjusted for maternal age and parity, revealed that non-spontaneously conceived dichorionic twin pregnancies were associated with a higher risk of very preterm birth (OR 2.20, 95% confidence interval 1.02-4.77, p<0.05), low birth weight (1.77, 1.21-2.61, p<0.01), very low birth weight (1.99, 1.13-3.49, p<0.05), NICU admission (1.66, 1.14-2.43, p<0.01), and fetal or neonatal death (3.21, 1.30-7.95, p<0.05). Multivariate analysis confirmed that the mean gestational age (p<0.01) and mean birth weight of the first (p<0.05) and second twins (p<0.01) were lower in the non-spontaneously conceived dichorionic twin pregnancy group. These associations were confirmed in the OI group analysis (n=39) but not in the ART group (n=65). Ovarian induction was associated with an increase in the risk of preterm and very preterm births (2.25, 1.06-4.75, p<0.05 and 3.47, 1.42-8.49, p<0.01, respectively), low and very low birth weights (2.87, 1.63-5.05, p<0.001 and 2.59, 1.33-5.07, p<0.01, respectively), NICU admission (2.92, 1.67-5.11, p<0.001) and fetal or neonatal death (4.20, 1.40-12.56, p<0.05). The mean gestational age (p<0.001) and mean birth weight of the first (p<0.01) and second twins (p<0.001) were also lower in the OI group. CONCLUSIONS: Twin pregnancies with dichorionic placentation following non-spontaneously conceived pregnancy are associated with a higher risk of adverse perinatal outcome compared with dichorionic spontaneously conceived twin pregnancies especially in case of ovarian induction alone.

Clinical relevance of placenta examination for the diagnosis of congenital toxoplasmosis.

BACKGROUND: Neonates with congenital toxoplasmosis, even asymptomatic at birth, should be treated early to reduce long-term sequelae. Postnatal diagnosis of congenital toxoplasmosis is essential because prenatal diagnosis fails to detect approximately 15% of cases or cannot be performed when maternal infection is acquired in late pregnancy. Detection of parasites in the placenta is one diagnostic approach to the early neonatal diagnosis of congenital toxoplasmosis. METHODS: The parasitic analyses of 102 placentas from cases of toxoplasmosis acquired during gestation were reviewed, with complete biologic follow-up of neonates. The value of quantitative PCR and mouse inoculation was assessed, and results are discussed in light of prenatal treatment and postnatal outcome. RESULTS: Congenital toxoplasmosis was diagnosed in 28 of the 102 cases. A prenatal diagnosis was obtained in only 16 cases. Specific IgM was detected in 57% of the babies at birth. A positive placental examination by PCR and mouse inoculation was the only evidence of infection in 3 neonates (11%) who were asymptomatic at birth. The sensitivities of PCR and mouse inoculation were 71% and 67%, respectively, and the specificities were 97% and 100%. Parasites were detected more often when maternal infection was acquired during the third trimester of pregnancy (P < 0.01), regardless the type of treatment. The sensitivity of IgM detection appeared to be related to maternal treatment since IgM was positive in 43% and 75% when mothers were treated or not, respectively (P < 0.01). Though 5/7 symptomatic infants had a positive placenta examination, there was no correlation between a positive placenta and the presence of clinical signs during the first year of life. The positive and negative predictive values of placental examination were 91% and 90%, respectively. CONCLUSION: Placental examination is an efficient tool for the early diagnosis of congenital toxoplasmosis.

Comparing the APGAR score representation in HL7 and OpenEHR formalisms.

Semantic interoperability, a prerequisite to eHealth projects, relies on sharing both information and knowledge models between information systems. Two of the standards of information models are HL7 v3 and the European norm, EN13606/OpenEHR. The paper compares both standards on a fragment of the prenatal medical record, the APGAR score. Two factors are compared: the formal representation of both information models, and the binding to knowledge models. The HL7v3 perinatality DMIM specification and the OpenEHR APGAR archetype were used. HL7v3 appears to be more formal than OpenEHR and able to represent in an easier way the clinical context. For both standards, the binding to reference terminologies such as LOINC is poor. We provide recommendations to improve the standards.

Nutritional and genetic determinants of vitamin B and homocysteine metabolisms in neural tube defects: a multicenter case-control study.

Neural tube defects (NTDs) are severe congenital malformations due to failure of neural tube formation in early pregnancy. The proof that folic acid prevents NTDs raises the question of whether other parts of homocysteine (Hcy) metabolism may affect rates of NTDs. This French case-control study covered: 77 women aged 17-42 years sampled prior to elective abortion for a severe NTDs (cases) and 61 women aged 20-43 years with a normal pregnancy. Plasma and erythrocyte folate, plasma B6, B12 and Hcy were tested as five polymorphisms MTHFR 677 C --> T, MTHFR 1298 A --> C, MTR 2756 A --> G, MTTR 66 A --> G and TCN2 776 C --> G. Cases had significantly lower erythrocyte folate, plasma folate, B12 and B6 concentrations than the controls, and higher Hcy concentration. The odds ratio was 2.15 (95% CI: 1.00-4.59) for women with the MTRR 66 A --> G allele and it was decreased for mothers carrying the MTHFR 1298 A --> C allele. In multivariate analysis, only the erythrocyte folate concentration (P = 0.005) and plasma B6 concentration (P = 0.020) were predictors. Red cell folate is the main determinant of NTDs in France. Folic acid supplement or flour fortification would prevent most cases. Increased consumption of vitamins B12 and B6 could contribute to the prevention of NTDs. Genetic polymorphisms played only a small role. Until folic acid fortification becomes mandatory, all women of reproductive age should consume folic acid in a multivitamin that also contains B12 and B6.

Pathophysiology of intracranial epidural haematoma following birth.

Epidural haematoma in newborn infants is rare, and few specific obstetrical data related to its formation are available in the literature. The aim of this study is to discuss the pathophysiology of this condition. EDH is always a post traumatic lesion and it is only possible if the insult has produced a cleavage of the dura mater from bone. Therefore, EDH results from the mechanical forces exerted on the foetal head during birth, with or with no instrumental interference. Although it is still unclear whether the injury (and dura mater cleavage) was directly caused by the forceps or had already been inflicted by natural forces, or a combination of both however, in some patients (with neither dystocia nor skull fracture), there is no basis for explaining EDH formation, apart from propulsion of the fore coming head through the birth canal. Excessive moulding, whether or not associated with iatrogenic trauma, has been incriminated in most cases of EDH. As dystocia cannot always be anticipated, EDH will remain an ever-present cause of morbidity in the neonatal population, albeit a rare occurrence.

Prenatal diagnosis of megacystis-microcolon-intestinal hypoperistalsis syndrome: contribution of amniotic fluid digestive enzyme assay and fetal urinalysis.

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.

Diagnosis-related pitfall of a lateral sacral cyst. Case report.

Because physical examination typically demonstrates normal findings in cases of low-back pain, diaglosis of the cause can be challenging. Frequent magnetic resonance imaging studies of the lumbosacral spine can typically lead to discovery of benign diseases and thus misinterpretation of these images. The authors report an unusual case in which a functional ovarian cyst was incidentally associated with a perineural cyst and mimicked a lateral sacral meningocele. In light of this, the authors recommend repeated examinations to avoid mistakes.
