    ABSTRACT: Our aim was to evaluate the rate of occurrence of chromosomal abnormalities, associated findings, and outcome in a series of cases of prenatally diagnosed clubfoot. We conducted a retrospective study of all cases of clubfoot diagnosed prenatally in the ultrasound unit of a French tertiary center from January 2004 through December 2011. Clubfoot was scored as complex or isolated depending on the presence or absence of another structural abnormality observed on sonographic examination. Data from 90 fetuses prenatally diagnosed with clubfoot were included in this study. Thirty-four cases were considered complex (38%) and 56 were considered isolated (62%). A chromosomal abnormality was identified in 10 of 33 of the fetuses with complex clubfoot and in 1 of 45 of those with isolated clubfoot (p < 0.001). Clubfoot was associated with a poor outcome in 5 of 52 cases of isolated clubfoot and in 31 of 34 cases associated with other structural defects (p < 0.001). The deformity was bilateral in 62 cases (69%) and unilateral in 28 (31%). No statistically significantly higher rate of poor outcome was identified when the deformity occurred bilaterally nor was a significantly higher rate of chromosomal abnormality noted in this condition. Aneuploidy and adverse pregnancy outcomes occur more commonly in prenatally diagnosed cases of complex clubfoot than in those of isolated clubfoot. Fetal karyotyping is required in cases of complex clubfoot, but the need for that procedure in isolated clubfoot remains controversial. © 2015 Wiley Periodicals, Inc.

    ABSTRACT: AimThe aim of this study was to evaluate two regimens of administration of sustained-release dinoprostone on the need for oxytocin induction of labor.Material and Methods We carried out an open prospective study comparing labor, maternal and neonatal outcomes after 12 h of prostaglandin cervical ripening insert versus 24 h of prostaglandin cervical ripening insert in 284 patients (142 ripenings at 12 h [P12 group] and 142 ripenings at 24 h [P24 group]).ResultsThe two groups were demographically similar. There was a significant difference in the need for artificial rupture of membranes/oxytocin induction of labor between the groups (49.3% for the P12 group vs 38% for the P24 group, P = 0.03). The delay between the beginning of ripening and delivery was significantly decreased in the P12 group, but the duration of active labor (6.6 h), the dose of oxytocics used (1326 UI), the rate of cesarean section, the rate of uterine hyperstimulation, the rates of hemorrhaging from delivery, the neonatal state and the experience of induction were similar in the two groups.Conclusion This study allows us to show for the first time that sustained-release of dinoprostone leads to spontaneous induction of labor without increasing the obstetrical risk in a majority of patients.

    ABSTRACT: It is common that intellectually gifted children-that is, children with an IQ ≥ 130-are referred to paediatric or child neuropsychiatry clinics for socio-emotional problems and/or school underachievement or maladjustment. These clinically-referred children with intellectual giftedness are thought to typically display internalizing problems (i.e., self-focused problems reflecting overcontrol of emotion and behavior), and to be more behaviorally impaired when "highly" gifted (IQ ≥ 145) or displaying developmental asynchrony (i.e., a heterogeneous developmental pattern, reflected in a significant verbal-performance discrepancy on IQ tests). We tested all these assumptions in 143 clinically-referred gifted children aged 8 to 12, using Wechsler's intelligence profile and the Child Behavior Checklist. Compared to a normative sample, gifted children displayed increased behavioral problems in the whole symptomatic range. Internalizing problems did not predominate over externalizing ones (i.e., acted-out problems, reflecting undercontrol of emotion and behavior), revealing a symptomatic nature of behavioral syndromes more severe than expected. "Highly gifted" children did not display more behavioral problems than the "low gifted." Gifted children with a significant verbal-performance discrepancy displayed more externalizing problems and mixed behavioral syndromes than gifted children without such a discrepancy. These results suggest that developmental asynchrony matters when examining emotional and behavioral problems in gifted children.

    ABSTRACT: INTRODUCTION: Intellectually gifted children are often thought to display a high risk for psychopathology. However, this assertion has received only few direct arguments to date, and there is in fact a lack of knowledge on this subject. The aim of this study was to compare trait-anxiety - which is considered as a sensitive and early indicator of psychoaffective difficulties in children - in intellectually gifted children to the norm. METHODS: One hundred and eleven children aged 8 to 12 and with an intellectual quotient (IQ) higher than 129 participated in the study. They were recruited in a hospital department of child and adolescent psychiatry and through psychologists' private practice, where they attended consultation because of academic underachievement and/or social maladjustment. All the children were examined by trained psychiatrists and psychologists: none had a present or past medical or psychiatric condition and, additionally, none had an elevated score on the French version of the Children's Depressive Rating Scale Revised (Moor & Mack, 1982). Parents filled in a questionnaire for the collection of socio-demographic data and children answered the French version of the Revised-Children's Manifest Anxiety Scale (R-CMAS; Reynolds, 1999), a 37-items self-assessment of trait-anxiety, the psychometric properties of which have been validated in children with high IQ. DATA ANALYSIS: Mean scores and subscores on the R-CMAS in the whole studied group and as a function of gender and age were compared to French normative data (Reynolds, 1999) by calculation of 95% confidence intervals; subgroups were compared using Student's t-tests. Proportions of children who's score and subscores exceeded anxiety cut-off norms were compared to normative data using chi-square tests. Statistical significance was considered at the P<0.05 level. RESULTS: The studied group comprised mainly boys, and members of a sibling. Parents mainly lived as man and wife, had high academic levels, and had a professional activity. The confidence intervals of the R-CMAS scores and subscores all comprised their normative value, which denotes that no difference was statistically significant. Comparisons for age and gender showed no significant difference. Proportions of results exceeding the cut-off scores and subscores did not significantly differ from the norms. DISCUSSION: General and dimensional trait-anxiety levels in the studied group were comparable to normative data. These results are in accordance with previous studies of trait-anxiety in children and adolescents with high IQ, which all showed normal or decreased levels. These findings do not corroborate the hypothesis that intellectual giftedness constitutes a risk factor for psychopathology. LIMITS: The studied group was a clinical one, which could limit the generalisation of the results. However, mental disorders were ruled out, and the psychometric and socio-demographic characteristics of the group were in keeping with those described for the general population of gifted children. Moreover, considering that participant children displayed academic underachievement and/or social maladjustment, it can be supposed that their anxiety levels were not lower than those in the general population of gifted children. Secondly, the potentially confusing effect of socio-demographic variables (underrepresentation of low socio-economic levels and single-parent families) could not be statistically taken into account, due to the absence of a specific control group. CONCLUSION: Intellectually gifted children seem not to display increased trait-anxiety. However, further studies are necessary to investigate psychological functioning in gifted children and their risk for psychopathology.

    ABSTRACT: OBJECTIVE: To report on the effectiveness of cyclophosphamide (CYC) to treat glucocorticoid (GC)-dependent giant-cell arteritis (GCA) and/or severe GC-related side effects. METHODS: Fifteen patients with GCA and treated with CYC were retrieved from the computerized patient-record system. Glucocorticoid dependence was defined as a prednisone dose of >20mg/day for 6 months or >10mg/day for 1 year in order not to relapse. Response to CYC was defined as improved clinical and biological findings. Remission was defined as a sustained absence (>12 months) of active signs of vasculitis at a daily GC dose of <7.5mg. A literature review searched PubMed for all patients diagnosed with GCA and who received CYC. RESULTS: Our 15 patients responded to monthly pulses of CYC, and all experienced a GC-sparing effect, including five patients who discontinued GC long term. At a median follow-up of 43 (range: 14-75) months after CYC, nine (53%) patients were still in remission and six (40%) had relapsed at 6 (3-36) months after the last CYC infusion. Twelve (80%) patients experienced side effects, leading to discontinuation of CYC in two (13%). A literature review retrieved 88 patients who received CYC: 66 for GC-dependent disease, 53 for GC toxicity, and 14 for severe organ involvement. Their median follow-up time was 24 (4-60) months. Among the 88 patients, 74 (84%) were responsive to CYC and 17 (19%) relapsed, although all were receiving a maintenance therapy with immunosuppressive agents (such as methotrexate). Twenty-nine (33%) patients experienced side effects and 11 (12.5%) discontinued treatment. CONCLUSION: Cyclophosphamide is an interesting option for GCA patients with GC-dependent disease or with severe GC-related side effects, especially when conventional immunosuppressive agents have failed.

    ABSTRACT: Targeted therapies booming in NSCLC deeply changed prognosis in some subsets of patients experiencing long survival. A priori identification (at time of diagnosis), of patients the most beneficiating from those often costly therapies is the new issue in thoracic oncology. For EGFR tyrosine kinase inhibitors (TKI), the situation is nowadays clear and molecular targeting relies on EGFR mutations diagnosis, that led to the first conditioned molecularbased registration for a drug in thoracic oncology. This routine molecular diagnosis has been made easier in France by French NCI huge effort to sponsor the 28 regional molecular biology platforms. Other targeted therapies are developed in phases 2 and 3 trials or used inside compassional programs targeting tumors with K-Ras, B-Raf, MEK1 mutations or with ALK fusion genes. French Intergroup (IFCT) with French NCI support, initiated a large prospective study, Biomarqueurs-France, to analyse the impact of the 17 000 routine yearly biomarkers analyses performed, by regional molecular biology platforms, on the routine care of French patients. This study will contribute to validate the biomarkers use, as early as at time of cancer diagnosis. Those biomarkers currently help us, or will help us in near future, for the routine care of lung cancer patients.

    ABSTRACT: The authors describe the methods and results of the main early intervention programs after discharge in the families of premature infants. There is great variability between the studies concerning the type, frequency, and length of interventions and the length of follow-up. Inconsistent improvement in cognitive and behavioral outcomes in the first 2years of life and at preschool age were noted. Most recent studies underscore that the intervention should take into account parental psychological status, focus on parent-infant interaction, and last a sufficiently long time.

    ABSTRACT: To evaluate prognostic and predictive molecular biomarkers in early-stage non-small cell lung carcinoma (NSCLC) receiving neoadjuvant chemotherapy. The IFCT-0002 trial compared two neoadjuvant regimens in 528 stages I to II NSCLC patients. DNA extraction of snap-frozen surgical samples taken from 208 patients receiving gemcitabine-cisplatin or paclitaxel-carboplatin regimens allowed for the identification of 3p allelic imbalance, Ras association domain family 1A (RASSF1A) and death-associated protein kinase 1 (DAPK1) promoter methylation, and epidermal growth factor receptor, K-ras, and TP53 mutations. Multivariate analysis identified prognostic and predictive effects of molecular alterations. A Bootstrapping approach was used to assess stability of the prognostic models generating optimism corrected indexes. RASSF1A methylation correlated significantly with shorter disease-free survival (DFS; adjusted HR = 1.88, 95% CI: 1.25-2.82, P = 0.0048) and shorter median overall survival (OS; adjusted HR = 2.01, 95% CI: 1.26-3.20, P = 0.020). A computed bootstrap resampling strategy led to a prognostic model, including RASSF1A, DAPK1, and tumor stage, dividing patients into three prognostic groups, with median OS ranging from 34 months for high-risk patients (HR for death = 3.85, 95% CI: 1.79-6.40) to more than 84 months for moderate (HR = 1.85, 95% CI: 0.97-3.52) and low-risk patients (reference group; P = 0.00044). In addition, RASSF1A methylation predicted longer DFS in patients treated with paclitaxel-carboplatin compared with gemcitabine-cisplatin (adjusted HR = 0.47, 95% CI: 0.23-0.97, P(interaction) = 0.042). Following neoadjuvant chemotherapy, RASSF1A methylation negatively impacted prognosis of early-stage NSCLC. Along with DAPK1 methylation and tumor stage, RASSF1A methylation allowed definition of three subgroups with strikingly different prognosis. Conversely, significantly longer DFS following paclitaxel-based neoadjuvant chemotherapy for patients whose tumors showed RASSF1A methylation suggested its predictive interest in stages I and II NSCLC.

    ABSTRACT: To determine risk factors for anal sphincter laceration and define situations with a high risk for such trauma in vacuum-assisted deliveries. Retrospective observational study of 1961 vacuum-assisted deliveries over a period of 5 years. French university hospital. All women who delivered with vacuum assistance. Third- and fourth-degree perineal tears were reviewed. The factors studied through univariate and multivariate logistic regression were the mother's age, parity, history of assisted delivery, cesarean section, gestational age, uterine fundal height, duration of the second stage of labor, head position at expulsion, epidural anesthesia, episiotomy, biparietal diameter and birthweight. Third- and fourth-degree perineal tears. There were 1.9% third-degree and no fourth-degree perineal tears. Risk factors identified were occipito-posterior position (odds ratio 4.7, p < 0.001), biparietal diameter (odds ratio 2.0 for each 5 mm increase, p= 0.004), duration of second stage (only significant when parity was ≥ 1; odds ratio 1.3 for each 10 min increase, p= 0.004) and nulliparity (decreasing effect according to duration of the second stage). The patterns of the association between these factors and the risk of perineal tears were different for nulli- and multiparous women. In a targeted population of women having vacuum-assisted deliveries, the association of specific risk factors allows clinicians to identify women who are at high risk of anal sphincter laceration.

    ABSTRACT: We assessed the prognostic and predictive value of β-tubulin III (TUBB3) expression, as determined by immunohistochemistry, in 412 non-small cell lung cancer (NSCLC) specimens from early-stage patients who received neoadjuvant chemotherapy (paclitaxel- or gemcitabine-based) in a phase III trial (IFCT-0002). We also correlated TUBB3 expression with K-Ras and EGF receptor (EGFR) mutations in a subset of 208 cryopreserved specimens. High TUBB3 protein expression was associated with nonsquamous cell carcinomas (P < 0.001) and K-Ras mutation (P < 0.001). The 127 (30.8%) TUBB3-negative patients derived more than 1 year of overall survival advantage, with more than 84 months median overall survival versus 71.7 months for TUBB3-positive patients [HR, 1.58; 95% confidence interval (CI), 1.11-2.25)]. This prognostic value was confirmed in multivariate analysis (adjusted HR for death, 1.51; 95% CI, 1.04-2.21; P = 0.031) with a bootstrapping validation procedure. TUBB3 expression was associated with nonresponse to chemotherapy (adjusted HR, 1.31; 95% CI, 1.01-1.70; P = 0.044) but had no predictive value (taxane vs. gemcitabine). Taking account of these clinical findings, we further investigated TUBB3 expression in isogenic human bronchial cell lines only differing by K-Ras gene status and assessed the effect of K-Ras short interfering RNA (siRNA) mediated depletion, cell hypoxia, or pharmacologic inhibitors of K-Ras downstream effectors, on TUBB3 protein cell content. siRNA K-Ras knockdown, inhibition of RAF/MEK (MAP-ERK kinase) and phosphoinositide 3-kinase (PI3K)/AKT signaling, and hypoxia were shown to downregulate TUBB3 expression in bronchial cells. This study is the first one to identify K-Ras mutations as determinant of TUBB3 expression, a chemoresistance marker. Our in vitro data deserve studies combining standard chemotherapy with anti-MEK or anti-PI3K drugs in patients with TUBB3-overexpressing tumors.

    ABSTRACT: To study the efficacy of bagged larvae on wound debridement compared with conventional treatment. Randomized, multicenter, controlled, prospective phase 3 trial with blinded assessment of outcome measures by a single observer. Two hospital referral centers in Caen and Lyon, France. Random sampling of 119 patients with a nonhealing, sloughy wound 40 cm(2) or smaller, less than 2 cm deep, and an ankle brachial index of 0.8 or higher. During a 2-week hospital stay, patients received either maggot debridement therapy (MDT) or conventional treatment. At discharge, conventional dressings were applied and a follow-up visit occurred at day 30. Percentage of slough in wounds at day 15. There was a significant difference between groups at day 8 (54.5% in the MDT group and 66.5% in the control group) (P = .04). The mean percentage of slough at day 15 was 55.4% in the MDT group and 53.8% in the control group (P = .78). Although MDT shows no significant benefit at day 15 compared with conventional treatment, debridement by MDT is significantly faster and occurs during the first week of treatment. Because there is no benefit in continuing the treatment after 1 week, another type of dressing should be used after 2 or 3 applications of MDT. clinicaltrials.gov Identifier: NCT01211236.

    ABSTRACT: The aim of this work was to evaluate myocardial strain analysis as a tool for the early detection of left ventricular functional changes in patients with cystic fibrosis. A total of 42 consecutive patients (mean age, 24 ± 7.5 years; 52% men) diagnosed with cystic fibrosis and referred for echocardiographic cardiac function assessment were prospectively enrolled. A group of healthy age-matched and gender-matched volunteers (n = 42) formed the reference population for echocardiographic comparisons. Left ventricular ejection fraction was conserved in both groups but was significantly lower in the cystic fibrosis group. Cardiac function assessment using Doppler tissue imaging parameters revealed that both systolic and diastolic measurements differed between the two groups: mitral peak systolic and diastolic velocities, as well as septal and lateral wall strain rates, were decreased in patients with cystic fibrosis, as was longitudinal strain of both the septal and lateral walls. Using strain measurements, subclinical changes in left ventricular function were found in patients with cystic fibrosis. These parameters were correlated with the degree of pulmonary involvement severity. These findings have potentially significant clinical implications for the outcomes and follow-up of patients with cystic fibrosis, meriting further studies.
