Intravitreal chemotherapy for vitreous seeding in retinoblastoma: Recent advances and perspectives.

For decades intravitreal chemotherapy (IViC) remained virtually banished from the therapeutic armamentarium against retinoblastoma, except as a heroic attempt of salvage before enucleation in only eyes with refractory vitreous seeding. Very recently, we have initiated a reappraisal of this route of administration by (1) profiling eligibility criteria, (2) describing a safety-enhanced injection procedure, (3) adjusting the tumoricidal dose of melphalan, and (4) reporting an unprecedented efficacy in terms of tumor control of vitreous seeding. Since then, intravitreal chemotherapy is being progressively implemented worldwide with great success, but still awaits formal validation by the ongoing prospective phase II clinical trial. As far as preliminary results are concerned, IViC appears to achieve complete vitreous response in 100% of the 35 newly recruited patients irrespective of the previous treatment regimen, including external beam radiotherapy and/or intra-arterial melphalan. In other words, vitreous seeding, still considered as the major cause of primary and secondary enucleation, can now be controlled by IViC. However, sterilization of vitreous seeding does not necessarily translate into eye survival, unless the retinal source of the seeds receives concomitant therapy. In conclusion, IViC, an unsophisticated and cost-effective treatment, is about to revolutionize the eye survival prognosis of vitreous disease in advanced retinoblastoma.

Pédiatrie. 3. Traitement du membre supérieur dans les hémiparésies congénitales: progrès et perspectives [Pediatrics. Upper limb treatment in congenital hemiparesis: progress and perspectives].

Congenital hemiparesis is one of the most frequent pediatric motor disorders. Upper limb rehabilitation of the hemiparetic child has considerably evolved during the last decade by the use of focal chemical denervation (intramuscular botulinum toxin) and the introduction of novel rehabilitation techniques such as constraint induced movement therapy or robotic reeducation.

Fourmis des bois en Suisse: état de la situation et perspectives de monitoring

The authors summarise their state of knowledge about wood ants and their role in the forest ecosystem. They also describe the situation in Switzerland, their past development and their conservation status. In several re- gions, mainly in the Plateau, wood ants seem to diminish, despite their total protection since 1966. The reasons for this regression are not well known, but the fragmentation of forest habitats in the Plateau region and direct damage to ant nests seem to play a certain role. A new project in which the development of wood ant nests is monitored in Swiss forest reserves (Formica-Forêts-CH) was recently started in the Swiss national park. It is to be extended, in collaboration with the forest services, over the whole of Switzerland.

Epilogue: Etre musulman en Suisse, hors mosquée. Notes méthodologiques et perspectives épistémologiques

En Suisse, un peu moins de 5 % de la population se déclarent musulmans. Originaires pour la majeure partie des grandes vagues migratoires de la fin du XXe siècle, les musulmans helvétiques sont le plus souvent identifiés individuellement. Ce livre présente la réalité institutionnelle et peu connue de l'islam en Suisse à partir de plusieurs enquêtes menées sur la manière dont il s'organise. Sa présence est très diversifiée selon les contextes cantonaux différents et les origines culturelles bien contrastées d'un musulman des Balkans, du Maghreb ou de la Turquie. Ces recherches menées par des sociologues et des politologues dessinent une mosaïque qui montre à partir de l'islam pratiquant et confessant qu'il ne peut être réduit aux formes conservatrices et violentes que certains considèrent comme la traduction obligée de toute posture musulmane. Cet ouvrage propose un portrait contrasté de l'islam en Suisse avec, d'une part, des ensembles qui tentent d'organiser légitimement leur culte et de maintenir leur héritage religieux et, d'autre part, des défis déterminants à relever pour l'intégration des fidèles, comme les liens avec le pays d'origine, l'indépendance financière des mosquées ou les questions relatives aux revendications religieuses ou culturelles de l'identité musulmane. A partir de la réalité musulmane, ce livre expose toute l'ambiguïté de nos sociétés « tolérantes » et « ouvertes », mais démunies et contradictoires face à l'émergence récente de la pluralité religieuse.

New perspectives in the use of ink evidence in forensic science: Part III: Operational applications and evaluation.

The research reported in this series of article aimed at (1) automating the search of questioned ink specimens in ink reference collections and (2) at evaluating the strength of ink evidence in a transparent and balanced manner. These aims require that ink samples are analysed in an accurate and reproducible way and that they are compared in an objective and automated way. This latter requirement is due to the large number of comparisons that are necessary in both scenarios. A research programme was designed to (a) develop a standard methodology for analysing ink samples in a reproducible way, (b) comparing automatically and objectively ink samples and (c) evaluate the proposed methodology in forensic contexts. This report focuses on the last of the three stages of the research programme. The calibration and acquisition process and the mathematical comparison algorithms were described in previous papers [C. Neumann, P. Margot, New perspectives in the use of ink evidence in forensic science-Part I: Development of a quality assurance process for forensic ink analysis by HPTLC, Forensic Sci. Int. 185 (2009) 29-37; C. Neumann, P. Margot, New perspectives in the use of ink evidence in forensic science-Part II: Development and testing of mathematical algorithms for the automatic comparison of ink samples analysed by HPTLC, Forensic Sci. Int. 185 (2009) 38-50]. In this paper, the benefits and challenges of the proposed concepts are tested in two forensic contexts: (1) ink identification and (2) ink evidential value assessment. The results show that different algorithms are better suited for different tasks. This research shows that it is possible to build digital ink libraries using the most commonly used ink analytical technique, i.e. high-performance thin layer chromatography, despite its reputation of lacking reproducibility. More importantly, it is possible to assign evidential value to ink evidence in a transparent way using a probabilistic model. It is therefore possible to move away from the traditional subjective approach, which is entirely based on experts' opinion, and which is usually not very informative. While there is room for the improvement, this report demonstrates the significant gains obtained over the traditional subjective approach for the search of ink specimens in ink databases, and the interpretation of their evidential value.

Rhétorique et cognition : perspectives théoriques et stratégies persuasives

D'une certaine manière, la rhétorique est un art cognitif. L'art de discourir en situation concrète dans l'espoir de faire adhérer l'auditoire à une thèse suppose une forte aptitude cognitive: celle de se représenter la façon dont l'auditoire lui-même se représente une situation rhétorique. Or, à partir du moment où agir sur les représentations d'autrui est facilité par des techniques rhétoriques ou sophistiques, la question de la tromperie verbale s'est immiscée dans des affaires de régulation sociale et, avec elle, des enjeux tant de crédibilité que de crédulité. Dans le cadre démocratique rendant encore plus aiguë une forme de dépendance à l'information d'autrui, la nécessité de croire tout comme la possibilité d'être leurré mettent à l'épreuve tant le fonctionnement social de la Cité que l'évaluation des informations et de leurs auteurs. Le but des contributions de cet ouvrage n'est pas de dénoncer les effets de certains schèmes argumentatifs que d'aucuns jugeraient fallacieux ni d'ajouter une couche nouvelle aux critiques des sophismes, mais d'étudier leur fonctionnement et leurs effets cognitifs hic et nunc. Quels sont les mécanismes langagiers et cognitifs qui expliquent la «performance» des arguments réputés fallacieux? Comment fonctionnent les stratégies rhétoriques à l'intersection entre cognition, sciences du langage et société? Cet ouvrage, issu du colloque Communication et Cognition: manipulation, persuasion et biais dans le langage, tenu à Neuchâtel du 26 au 28 janvier 2011, propose plusieurs propositions originales ou hypothèses stimulantes dans l'espoir qu'elles inspireront tant les chercheurs spécialisés en rhétorique et sciences du langage à aller voir du côté de la psychologie cognitive que les spécialistes de ce domaine à mettre en évidence la rhétoricité de leurs recherches. English version: In a way, rhetoric is a cognitive art. The art of speaking in concrete situations in the hope of gaining the audience's consent on a given issue requires the operation of a cognitive ability: that of being able to represent the way an audience represents itself a rhetorical situation. Nonetheless, once we consider that rhetorical or sophistic techniques influence people's representations, verbal deception becomes a matter of social regulation, together with issues of credibility and credulity. In a democratic context fostering a form of dependence towards other people's information, the necessity of believing everything and the possibility of being duped are challenges for both the social management of the City and the evaluation of information and of its sources. The contribution of the chapters of this volume is neither to be found in the condemnation of the fallacious effects of specific argument schemes nor in the addition of yet another layer to fallacy criticism, but in the study of how fallacies work, hic et nunc. What are the linguistic and cognitive mechanisms at play behind the "performance" of fallacious arguments? How do rhetorical strategies work at the interface of cognition, language science and society? This book gathers papers that were presented during the international conference Communication & Cognition: manipulation, persuasion and biases in language, held at the University of Neuchâtel in January 2011. A number of original proposals and stimulating hypotheses emerge from them: we hope that these will inspire researchers in the language sciences who specialise in rhetoric to take on board cognitive scientific insights but also researchers in cognitive science to engage with the rhetoricity of their own research.

Hyperuricaemia and gout: state of the art and future perspectives.

Major progress has been made in the past decade in understanding the pathogenesis and treatment of gout. These advances include identification of the genetic and environmental risk factors for gout, recognition that gout is an important risk factor for cardiovascular disease, elucidation of the pathways regulating the acute gout attack and the development of novel therapeutic agents to treat both the acute and chronic phases of the disease. This review summarises these advances and highlights the research agenda for the next decade.

Parenteral anticoagulants in heart disease: Current status and perspectives (Section II). Position Paper of the ESC Working Group on Thrombosis - Task Force on Anticoagulants in Heart Disease.

Anticoagulants are a mainstay of cardiovascular therapy, and parenteral anticoagulants have widespread use in cardiology, especially in acute situations. Parenteral anticoagulants include unfractionated heparin, low-molecular-weight heparins, the synthetic pentasaccharides fondaparinux, idraparinux and idrabiotaparinux, and parenteral direct thrombin inhibitors. The several shortcomings of unfractionated heparin and of low-molecular-weight heparins have prompted the development of the other newer agents. Here we review the mechanisms of action, pharmacological properties and side effects of parenteral anticoagulants used in the management of coronary heart disease treated with or without percutaneous coronary interventions, cardioversion for atrial fibrillation, and prosthetic heart valves and valve repair. Using an evidence-based approach, we describe the results of completed clinical trials, highlight ongoing research with currently available agents, and recommend therapeutic options for specific heart diseases.

Désensibilisation: vers de nouvelles perspectives [Allergen specific immunotherapy: review of new perspectives].

Allergic diseases constitute a health problem worldwide. More than just a treatment option, the classical desensitization (SIT--Specific immunotherapy) by subcutaneous injection has profiled over time as a unique approach, able to attenuate the immune response to allergic stimuli proved. For a long time conservative, desensitization has now progressed in the knowledge of allergens, in the understanding of the mechanisms involved in immune response and in production techniques. From recombinants to alternative routes of allergen delivery, this article gives an overview of new perspectives and assesses SIT in order to provide guidance to the general physician before choosing to initiate such treatment or not in patients with respiratory allergy.

Thérapie focale du cancer de la prostate: rationnel, résultats et perspectives [Focal therapy in prostate cancer: rationale, results and perspectives].

Focal therapy is a novel treatment strategy in prostate cancer aiming to treat only the area of the gland harbouring clinically significant disease. The overall objective is to maintain the oncological benefit of active treatment while minimising treatment-related morbidity. Leading centres are currently evaluating various minimally invasive technologies in a rigorous manner. Oncological and functional results in mid-term are encouraging with low rate of urinary incontinence and erectile dysfunction. However, the oncological outcome needs to be evaluated in the long-term in the light of the prolonged natural history of the disease.
