Planned delivery route of preterm breech singletons, and neonatal and 2-year outcomes: a population-based cohort study.

OBJECTIVE: To assess whether planned route of delivery is associated with perinatal and 2-year outcomes for preterm breech singletons. DESIGN: Prospective nationwide population-based EPIPAGE-2 cohort study. SETTING: France, 2011. SAMPLE: Three hundred and ninety women with breech singletons born at 26-34 weeks of gestation after preterm labour or preterm prelabour rupture of membranes. METHODS: Propensity-score analysis. MAIN OUTCOME MEASURES: Survival at discharge, survival at discharge without severe morbidity, and survival at 2 years of corrected age without neurosensory impairment. RESULTS: Vaginal and caesarean deliveries were planned in 143 and 247 women, respectively. Neonates with planned vaginal delivery and planned caesarean delivery did not differ in survival (93.0 versus 95.7%, P = 0.14), survival at discharge without severe morbidity (90.4 versus 89.9%, P = 0.85), or survival at 2 years without neurosensory impairment (86.6 versus 91.6%, P = 0.11). After applying propensity scores and assigning inverse probability of treatment weighting, as compared with planned vaginal delivery, planned caesarean delivery was not associated with improved survival (odds ratio, OR 1.31; 95% confidence interval, 95% CI 0.67-2.59), survival without severe morbidity (OR 0.75, 95% CI 0.45-1.27), or survival at 2 years without neurosensory impairment (OR 1.04, 95% CI 0.60-1.80). Results were similar after matching on propensity score. CONCLUSIONS: No association between planned caesarean delivery and improved outcomes for preterm breech singletons born at 26-34 weeks of gestation after preterm labour or preterm prelabour rupture of membranes was found. The route of delivery should be discussed with women, balancing neonatal outcomes with the higher risks of maternal morbidity associated with caesarean section performed at low gestational age.

Performance of semiconductor sequencing platform for non-invasive prenatal genetic screening for fetal aneuploidy: results from a multicenter prospective cohort study in a clinical setting.

OBJECTIVE: To validate and evaluate the performance metrics of the high-throughput semiconductor sequencing platform, Ion Proton®, in non-invasive prenatal genetic screening (NIPS) for common fetal aneuploidies in a clinical setting. METHODS: This prospective cohort study included 2505 pregnant women from eight academic genetics laboratories (695 high risk for trisomy 21 (risk ≥ 1/250) pregnancies in a validation study, and 1810 such pregnancies, without ultrasound anomalies, in a real-life NIPS clinical setting). Outcome was available for all cases in the validation cohort and for 521 in the clinical cohort. Cell-free DNA from plasma samples was sequenced using the Ion Proton sequencer, and sequencing data were analyzed using the open-access software, WISECONDOR. Performance metrics for detection of trisomies 21, 18 and 13 were calculated based on either fetal karyotype result or clinical data collected at birth. We also evaluated the failure rate and compared three methods of fetal fraction quantification (RASSF1A assay, and DEFRAG and SANEFALCON software). RESULTS: Results from both cohorts were consistent and their gestational age was not significantly different so their data were combined to increase the sample size for analysis. Sensitivities and specificities, respectively, were as follows: for trisomy 21, 98.3% (95% CI, 93.5-99.7%) and 99.9% (95% CI, 99.4-100%); for trisomy 18, 96.7% (95% CI, 80.9-99.8%) and 100% (95% CI, 99.6-100%); and for trisomy 13, 94.1% (95% CI, 69.2-99.7%) and 100% (95% CI, 99.6-100%). Our failure rate was 1.2% initially and as low as 0.6% after retesting some of the failed samples. Fetal fraction estimation by the RASSF1A assay was consistent with DEFRAG results, and both were adequate for routine diagnosis. CONCLUSIONS: We describe one of the largest studies evaluating Ion Proton-based NIPS and the first clinical study reporting pregnancy outcome in a large series of patients. This platform is highly efficient in detecting the three most common trisomies. Our protocol is robust and can be implemented easily in any medical genetics laboratory. Copyright © 2018 ISUOG.

Alcohol use and self-perceived mental health status among pregnant and breastfeeding women in Canada: a secondary data analysis.

OBJECTIVE: To estimate the prevalence of alcohol consumption during pregnancy and while breastfeeding in Canada from 2003 to 2010, and to test the relation between self-perceived mental health status and alcohol consumption during pregnancy and while breastfeeding. DESIGN: Secondary analysis of four cycles of the Canadian Community Health Survey, a population-based cross-sectional survey. SETTING: Canada. SAMPLE: A total of 18 612 pregnant and 15 836 breastfeeding women. METHODS: The prevalence of alcohol consumption during pregnancy and while breastfeeding and 95% confidence intervals (CI) were calculated by province and territory, and cycle. The relation between self-perceived mental health status and alcohol consumption during pregnancy and while breastfeeding was explored using quasi-Poisson regression models. MAIN OUTCOME MEASURES: Alcohol consumption during pregnancy and while breastfeeding, and self-perceived mental health status. RESULTS: In Canada, between 2003 and 2010, approximately one in every ten pregnant women (9.9%; 95%CI 9.2-10.5%) and two in every ten breastfeeding women (20.3%; 95%CI 19.4-21.2%) women consumed alcohol. Women with a lower self-perceived mental health status (i.e. 'good') were 1.40 (95%CI 1.18-1.67, P < 0.001) times more likely to have consumed alcohol during pregnancy, compared with women with an 'excellent' self-perceived mental health. There were no notable differences between the categories of mental health status in regard to alcohol consumption while breastfeeding. CONCLUSION: Despite public health efforts in Canada, a significant proportion of pregnant and breastfeeding women consume alcohol. It is imperative that a standard screening protocol be initiated among pregnant and breastfeeding women, especially in high-risk populations (e.g. women utilising substance abuse treatment programs). TWEETABLE ABSTRACT: In Canada in 2003-2010, approximately 10% of pregnant and 20% of breastfeeding women consumed alcohol.

Isolated and syndromic brachydactylies: Diagnostic value of hand X-rays.

Brachydactyly, or shortening of the digits, is due to the abnormal development of phalanges, metacarpals and/or metatarsals. This congenital malformation is common, easily detectable clinically but often requires additional radiological exploration. Radiographs are essential to characterize the type of brachydactyly and to show the location of the bone shortening, as well as any associated malformation. This article reviews the radiological findings for isolated brachydactylies (according to the types classified by Bell, and Temtamy and McKusick) and for brachydactylies that are part of complex multisystem malformation syndromes. If warranted by the clinical and radiological examinations, a genetic analysis (molecular and/or cytogenetic) can confirm the etiologic diagnosis.

Mutation update and uncommon phenotypes in a French cohort of 96 patients with WFS1-related disorders.

WFS1 mutations are responsible for Wolfram syndrome (WS) characterized by juvenile-onset diabetes mellitus and optic atrophy, and for low-frequency sensorineural hearing loss (LFSNHL). Our aim was to analyze the French cohort of 96 patients with WFS1-related disorders in order (i) to update clinical and molecular data with 37 novel affected individuals, (ii) to describe uncommon phenotypes and, (iii) to precise the frequency of large-scale rearrangements in WFS1. We performed quantitative polymerase chain reaction (PCR) in 13 patients, carrying only one heterozygous variant, to identify large-scale rearrangements in WFS1. Among the 37 novel patients, 15 carried 15 novel deleterious putative mutations, including one large deletion of 17,444 base pairs. The analysis of the cohort revealed unexpected phenotypes including (i) late-onset symptoms in 13.8% of patients with a probable autosomal recessive transmission; (ii) two siblings with recessive optic atrophy without diabetes mellitus and, (iii) six patients from four families with dominantly-inherited deafness and optic atrophy. We highlight the expanding spectrum of WFS1-related disorders and we show that, even if large deletions are rare events, they have to be searched in patients with classical WS carrying only one WFS1 mutation after sequencing.

[Rare case of bilateral pulmonary agenesis and prenatal diagnosis]. / Diagnostic anténatal d'une agénésie pulmonaire bilatérale : une observation exceptionnelle.

Bilateral pulmonary agenesis (BPA) is a rare congenital lung malformation. The prognosis is severe as it is incompatible with extra-uterine life. Although multiple prenatal imaging modalities are developed, the prenatal diagnosis of BPA remains problematic. We report a case of BPA observed in our unity and for which the diagnosis was not clearly identified during the evaluation. This report illustrates the need to consider all the imaging aspects and particularly during US examination suspecting BPA.

Everolimus- and sirolimus-eluting stents in patients with and without ST-segment elevation myocardial infarction.

AIMS: Everolimus-eluting stents (EES) were superior to sirolimus-eluting stents (SES) in a dedicated myocardial infarction trial, a finding that was not observed in trials with low percentages of ST-elevation myocardial infarction (STEMI). Therefore, this study sought to investigate the influence of clinical presentation on outcome after EES and SES implantation. METHODS: A pooled population of 1602 randomised patients was formed from XAMI (acute MI trial) and APPENDIX-AMI (all-comer trial). Primary outcome was cardiac mortality, MI and target vessel revascularisation at 2 years. Secondary endpoints included definite/probable stent thrombosis (ST). Adjustment was done using Cox regression. RESULTS: In total, 902 EES and 700 SES patients were included, of which 44 % STEMI patients (EES 455; SES 257) and 56 % without STEMI (EES 447; SES 443). In the pooled population, EES and SES showed similar outcomes during follow-up. Moreover, no differences in the endpoints were observed after stratification according to presentation. Although a trend toward reduced early definite/probable ST was observed in EES compared with SES in STEMI patients, long-term ST rates were low and comparable. CONCLUSIONS: EES and SES showed a similar outcome during 2-year follow-up, regardless of clinical presentation. Long-term safety was excellent for both devices, despite wide inclusion criteria and a large sub-population of STEMI patients.

[When should evoke prenatal paternal uniparental disomy 14?]. / Quand faut-il évoquer en anténatal une disomie uniparentale paternelle 14 ?

The paternal uniparental disomy 14 is a rare malformation syndrome whose postnatal pathognomonic sign is the deformation of the rib as coat hanger. In prenatal, ultrasonographic signs are major recurrent polyhydramnios, a narrow thorax and deformed long bones short and sometimes other anomalies including ends. The authors report one rare case of prenatal paternal uniparental disomy 14 with the deformation of the rib as coat hanger. Prenatally, the narrow deformed thorax can be searched by ultrasound three-dimensional (3D) and/or helical CT and thus represent an aid to prenatal diagnosis.

Antidepressive effect of mirtazapine in post-myocardial infarction depression is associated with soluble TNF-R1 increase: data from the MIND-IT.

BACKGROUND: Depressive disorder after myocardial infarction (MI) is associated with increased cardiac morbidity and mortality. Immune activity such as inflammation might be implicated as an underlying mechanism. The purpose of this study is to investigate whether the response to an antidepressant in post-MI depression is associated with changes of inflammatory markers in serum. METHODS: In a double-blind placebo-controlled study with mirtazapine 30 mg/day (50 patients), the antidepressive effect was related to immune activation parameters. The cytokines interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α), the soluble cytokine receptors sIL-6R, sTNF-R1 and sTNF-R2, and the inflammation-sensitive plasma proteins C-reactive protein and neopterin were assessed. RESULTS: Subgroup analyses revealed a highly significant correlation of pronounced sTNF-R1 increase with a decrease in depressive symptoms in antidepressant responders. CONCLUSION: Significant effects on inflammation accompany the therapeutic efficacy of mirtazapine in contrast to the therapeutic efficacy of placebo and the nontherapeutic efficacy of mirtazapine.

Evolution of a patient with Bohring-Opitz syndrome.

We detailed the story from birth to the age of 5 years 9 months, of the oldest patient reported with a Bohring-Opitz syndrome with the three main diagnostic criteria: characteristic facial appearance, fixed contractures of the upper limbs and severe feeding difficulties. The facial anomalies described in our patient were microcephaly, bitemporal narrowing, "puffy" cheeks, forehead naevus flammeus, hypoplastic orbital ridges, prominent eyes, broad nasal bridge, high arched palate, buccal-alveola frenula and retrognathism. The magnetic resonance imaging (MRI) of the brain showed a hypoplastic corpus callosum and a narrowed upper cervical canal; and the cervical MRI showed a malformation of the atlas consisting in an agenesis of the anterior arch and an anterior slip of the posterior arch. We focused on her neurological and nutritional evolution. Despite the gastrostomy and a Nissen fundoplication at age 7 months, she still had developmental growth delays overall (<3rd centile). At 3 years 9 months of age, she began to put on weight quickly, which seemed to be atypical. Meanwhile she developed epilepsy, which was controlled with specific drugs. Currently, she is 5 years 9 months old and has significant psychomotor retardation, although this disease is often fatal in early childhood, due to obstructive apnea and unexplained bradycardia.

[Is the bronchial atresia prenatal diagnosis possible?]. / Le diagnostic anténatal d'atrésie bronchique est-il possible ?

Bronchial atresia is a rare congenital malformation of the lung. The main-stem segmental or lobar bronchus fails to construct normally, which can lead to accumulation of mucus within the distal bronchi or lung hyperinflation of the obstructed lobe. The prenatal diagnosis is rare and difficult. We report two cases of fetuses who presented pathological examination of the lung on the ultrasonography, at 22 weeks of gestation, suspect of prenatal bronchial atresia diagnosis. We analysed this malformation through a literature review in order to discuss differential diagnosis to be evoked, as well as appropriate perinatal management.

Inhalation induction using sevoflurane in children: the single-breath vital capacity technique compared to the tidal volume technique*.

The single-breath vital capacity technique is suitable for inhalation induction of anaesthesia, using sevoflurane in children aged > 5 years. The purpose of this randomised trial was to compare the single breath vital capacity technique with the conventional tidal volume technique. Seventy- three ASA 1 or 2 children were instructed during the pre-operative visit in the vital capacity technique. The main criterion measured was time to loss of the eyelash reflex. Induction was performed using a circle-absorber breathing circuit primed with sevoflurane 7% in 50% nitrous oxide/oxygen with 6 l.min(-1) fresh gas flow. Time required for induction, haemodynamic changes, airway tolerance and side-effects were recorded. The children's opinion on the technique used was scored using a visual analogue scale (0-100) and a Smiley scale (0-10). The time to loss of the eyelash reflex was found to be reduced in the vital capacity group compared to the tidal volume group. The time to central myosis, to achieve bispectral index values 60 and 40, haemodynamic changes, respiratory events and side-effect incidences were similar in both groups. However, we found that the vital capacity technique was preferred by the children to the tidal volume technique.

[Value of multidetector-row computed tomography for infantile renovascular hypertension: report of two cases]. / Apport de la tomodensitométrie multicoupe dans l'hypertension rénovasculaire du nourrisson: à propos de deux cas.

The work-up of renovascular hypertension (10% of children hypertension cases) benefits from multiple imaging modalities. These two cases show the difficulties encountered with infant and underscore "the major role" of the computed tomography angiography within for diagnosis and management. Indeed CTA allows reproducible studies of abdominal vessels at the expense of radiation exposure.

Prenatal diagnosis of a cleidocranial dysplasia-like phenotype associated with a de novo balanced t(2q;6q)(q36;q16) translocation.

Cleidocranial dysplasia (CCD) is a congenital disorder of bone development characterized by persistently open or delayed closure of cranial sutures and wormian bones, hypoplastic and/or aplastic clavicles, wide pubic symphysis, dental anomalies and short stature. The condition is inherited as an autosomal-dominant trait and the human CBFA1 gene has been identified as the CCD gene. We describe a prenatal form of the skeletal disorder that included clavicular hypoplasia, absence of ossification of the cranial parietal bones and very poor ossification of the frontal and pubic bones. Growth restriction affecting only the long bones was also noted. The fetal karyotype revealed an apparently de novo balanced t(2q;6q)(q36;q16) translocation. This particular form of skeletal disorder associated with the absence of family history and an apparently de novo balanced translocation led the parents to opt for termination of the pregnancy.

Prenatal diagnosis of sacrococcygeal teratoma with constitutional partial monosomy 7q/trisomy 2p.

We report the prenatal diagnosis of a fetus with sacrococcygeal teratoma and facial dysmorphism attributed to a constitutional terminal deletion of chromosome 7q and partial trisomy of chromosome 2p likely resulting from a de novo balanced translocation. The cytogenetic abnormality was diagnosed prenatally after sonographic detection of teratoma and confirmed on peripheral blood cells at birth. The newborn died of post-operative complications at seven days of age. FISH analysis demonstrated haploinsufficiency of HLXB9, a gene identified in the triad of a presacral mass (teratoma or anterior meningocele), sacral agenesis, and anorectal malformation, which constitutes the Currarino syndrome. Despite the absence of other features of the triad, the teratoma observed in the fetus we describe might represent a partial form of Currarino syndrome.

Limitations of ultrasonography for diagnosing white matter damage in preterm infants.

DESIGN: Prospective cohort study. SETTING: A neonatal intensive care unit in France. PATIENTS: All preterm infants (

A search tool based on 'encapsulated' MeSH thesaurus to retrieve quality health resources on the internet.

In the year 2001, the Internet has become a major source of health information for the health professional and the Netizen. The objective of Doc' CISMeF (D'C) was to create a powerful generic search tool based on a structured information model which 'encapsulates' the MeSH thesaurus to index and retrieve quality health resources on the Internet. To index resources, D'C uses four sections in its information model: 'meta-term', keyword, subheading, and resource type. Two search options are available: simple and advanced. The simple search requires the end-user to input a single term or expression. If this term belongs to the D'C information structure model, it will be exploded. If not, a full-text search is performed. In the advanced search, complex searches are possible combining Boolean operators with meta-terms, keywords, subheadings and resource types. D'C uses two standard tools for organising information: the MeSH thesaurus and the Dublin Core metadata format. Resources included in D'C are described according to the following elements: title, author or creator, subject and keywords, description, publishers, date, resource type, format, identifier, and language.

Fetal lung volume: estimation at MR imaging-initial results.

PURPOSE: To plot normal fetal lung volume (FLV) obtained with fast spin-echo magnetic resonance (MR) images against gestational age; to investigate the correlation between lung growth and fetal presentation, sex, and ultrasonographic (US) biometric measurements; and to investigate its potential application in fetuses with thoracoabdominal malformations. MATERIALS AND METHODS: In a prospective multicenter study, 336 fetuses suspected of having central nervous system disorders underwent fast spin-echo T2-weighted lung MR imaging. Data obtained at 21-38 weeks gestation in 215 fetuses without thoracoabdominal malformations and with normal US biometric findings were selected for an FLV normative curve. FLV measurements obtained at pathologic examination with an immersion method were compared with MR FLV measurements in 11 fetuses. MR FLV values in 16 fetuses with thoracoabdominal malformations were compared with the normative curve. RESULTS: Normal FLV increased with gestational age as a power curve; the spread of values increased with age. Interobserver correlation was excellent (R(2) = 0.96). FLV measurements at MR imaging were 0.90 times those at pathologic examination. A constant ratio (0.78) between FLV on the left and right sides was observed. No significant difference in FLV was observed between fetal presentations. Normal FLV was observed in all fetuses with cystic adenomatoid malformations and in four of six with oligohydramnios. Lowest FLV values were observed in fetuses with diaphragmatic hernia. CONCLUSION: In fetuses with normal lungs, FLV distribution against gestational age is easily assessed in utero with fast spin-echo T2-weighted MR imaging. These preliminary findings illustrate the potential for comparing FLV measurements in fetuses at risk of lung hypoplasia with normative values.
