    Le syndrome d apnĂ©es obstructives du sommeil (SAOS) est une affection frĂ©quente touchant 5 % de la population. La chirurgie d avancĂ©e maxillo-mandibulaire (MMA) en 1Ăšre intention est une alternative thĂ©rapeutique Ă  la pression positive continue. Il s agit d une Ă©tude rĂ©trospective prospective monocentrique de 34 cas, opĂ©rĂ©s entre 1995 et 2009 dans le service avec un suivi moyen de 12,5 annĂ©es. Les patients ont Ă©tĂ© revus et Ă©valuĂ©s sur la polysomnographie, les tĂ©lĂ©radiographies et le questionnaire de qualitĂ© de vie. L objectif principal Ă©tait d Ă©valuer Ă  plus de 3 ans l ensemble des patients traitĂ©s par MMA via l index apnĂ©es-hypopnĂ©es (IAH) afin de mesurer son efficacitĂ© Ă  long terme. Le taux de succĂšs Ă  long terme dĂ©fini par un IAH<10 et une diminution de plus de 50 % de l IAH Ă©tait de 28 %. Pour la moitiĂ© des patients non guĂ©ris, la diminution de l IAH se situait entre 50 et 80 %. Le succĂšs Ă©tait de 100 % pour les patients jeunes (<45 ans), minces (IMC<25 kg/m2), avec un IAH<45 Ă©vĂšnements/h, un angle SNB<75 et un espace minimum rĂ©tro-basi-lingual < 8 mm, prĂ©parĂ©s orthodontiquement et sans co-morbiditĂ© associĂ©e. Cette chirurgie Ă©tait stable sur le plan squelettique. Une avancĂ©e modĂ©rĂ©e du maxillaire associĂ©e Ă  une impaction antĂ©rieure a permis d amĂ©liorer le rĂ©sultat esthĂ©tique tout en conservant un bon allongement du ramus mandibulaire. L effet indĂ©sirable majeur Ă©tait reprĂ©sentĂ© par les troubles de la sensibilitĂ© dans le territoire du nerf alvĂ©olaire infĂ©rieur. Cette intervention est une alternative thĂ©rapeutique efficace en 1Ăšre intention, mĂȘme Ă  long terme, pour des indications posĂ©es sur des critĂšres prĂ©cis. La prĂ©paration orthodontique est indispensable.GRENOBLE1-BU MĂ©decine pharm. (385162101) / SudocSudocFranceF

    Outcomes in newly diagnosed elderly glioblastoma patients after concomitant temozolomide administration and hypofractionated radiotherapy

    This study aimed to analyze the treatment and outcomes of older glioblastoma patients. Forty-four patients older than 70 years of age were referred to the Paul Strauss Center for chemotherapy and radiotherapy. The median age was 75.5 years old (range: 70-84), and the patients included 18 females and 26 males. The median Karnofsky index (KI) was 70%. The Charlson indices varied from 4 to 6. All of the patients underwent surgery. O6-methylguanine-DNA methyltransferase (MGMT) methylation status was determined in 25 patients. All of the patients received radiation therapy. Thirty-eight patients adhered to a hypofractionated radiation therapy schedule and six patients to a normofractionated schedule. Neoadjuvant, concomitant and adjuvant chemotherapy regimens were administered to 12, 35 and 20 patients, respectively. At the time of this analysis, 41 patients had died. The median time to relapse was 6.7 months. Twenty-nine patients relapsed, and 10 patients received chemotherapy upon relapse. The median overall survival (OS) was 7.2 months and the one- and two-year OS rates were 32% and 12%, respectively. In a multivariate analysis, only the Karnofsky index was a prognostic factor. Hypofractionated radiotherapy and chemotherapy with temozolomide are feasible and acceptably tolerated in older patients. However, relevant prognostic factors are needed to optimize treatment proposals

    Complete exon sequencing of all known Usher syndrome genes greatly improves molecular diagnosis

    <p>Abstract</p> <p>Background</p> <p>Usher syndrome (USH) combines sensorineural deafness with blindness. It is inherited in an autosomal recessive mode. Early diagnosis is critical for adapted educational and patient management choices, and for genetic counseling. To date, nine causative genes have been identified for the three clinical subtypes (USH1, USH2 and USH3). Current diagnostic strategies make use of a genotyping microarray that is based on the previously reported mutations. The purpose of this study was to design a more accurate molecular diagnosis tool.</p> <p>Methods</p> <p>We sequenced the 366 coding exons and flanking regions of the nine known USH genes, in 54 USH patients (27 USH1, 21 USH2 and 6 USH3).</p> <p>Results</p> <p>Biallelic mutations were detected in 39 patients (72%) and monoallelic mutations in an additional 10 patients (18.5%). In addition to biallelic mutations in one of the USH genes, presumably pathogenic mutations in another USH gene were detected in seven patients (13%), and another patient carried monoallelic mutations in three different USH genes. Notably, none of the USH3 patients carried detectable mutations in the only known USH3 gene, whereas they all carried mutations in USH2 genes. Most importantly, the currently used microarray would have detected only 30 of the 81 different mutations that we found, of which 39 (48%) were novel.</p> <p>Conclusions</p> <p>Based on these results, complete exon sequencing of the currently known USH genes stands as a definite improvement for molecular diagnosis of this disease, which is of utmost importance in the perspective of gene therapy.</p

    7. L’eau et les exploitations miniùres : d’une contrainte à une richesse

    Les activitĂ©s liĂ©es aux mines et aux carriĂšres ont toujours Ă©tĂ© en conflit avec la gestion de l’eau (cf. IV.19). Quand l’exploitation souterraine se situe sous le niveau de la nappe, le pompage et l’évacuation de l’eau sont indispensables. Les quantitĂ©s pompĂ©es peuvent devenir trĂšs importantes. Ainsi, de 1970 Ă  1995, 80 millions de m3 d’eau par an (la consommation de 1,5 million d’habitants) Ă©taient pompĂ©s dans le bassin houiller lorrain, et seulement 35 % du total de ces eaux d’exhaure* Ă©tai..

    Du thorium, de l'ionium et du polonium ont Ă©tĂ© introduits ensemble dans une Ă©mulsion, les parcours α ont Ă©tĂ© mesurĂ©s et comparĂ©s Ă  une courbe calculĂ©e parcours-Ă©nergie. Des prĂ©cautions chimiques et autres nous ont permis de ne pas ĂȘtre gĂȘnĂ©s par les dĂ©rivĂ©s radioactifs du thorium. L'Ă©nergie pondĂ©rĂ©e des α Ă©mis par 232Th est 3,990 ± 0,020 MeV et, si on admet, d'aprĂšs Mlle Albouy, 75 keV d'Ă©cart entre les deux raies α, celles-ci ont pour Ă©nergie 4,008 ± 0,020 MeV et 3,933 ± 0,020 MeV

    Transferability of geoscientific information from various sources (study sites, underground rock laboratories, natural analogues) to support safety cases for radioactive waste repositories in argillaceous formations

    No full text
    In studies related to deep geological disposal of radioactive waste, it is current practice to transfer external information (e.g. from other sites, from underground rock laboratories or from natural analogues) to safety cases for specific projects. Transferable information most commonly includes parameters, investigation techniques, process understanding, conceptual models and high-level conclusions on system behaviour. Prior to transfer, the basis of transferability needs to be established. In argillaceous rocks, the most relevant common feature is the microstructure of the rocks, essentially determined by the properties of clay–minerals. Examples are shown from the Swiss and French programmes how transfer of information was handled and justified. These examples illustrate how transferability depends on the stage of development of a repository safety case and highlight the need for adequate system understanding at all sites involved to support the transfer
