Multi-mechanism modeling of proportional and non-proportional ratchetting of stainless steel 304

International audienceThis work is devoted to a survey of the multi-mechanism (MM) models proposed in literature during the last two decades. This MM approach is a possible alternative to the wide-spread Chaboche’s model when modeling complex material behavior. Here, the description of the cyclic behavior under complex loading histories is in the focus. The capabilities of two recent versions of the MM models are demonstrated through the simulation of cyclic proportional and non-proportional loading paths under stress or the combination of stress–strain control. The reliability of the two MM models is investigated through the study of the mechanical behavior of a 304 stainless steel (304 SS) at room temperature. Beside the assessment of the stress–strain overall behavior, the local contribution of stress and strains at each mechanism level is discussed

Bipolar Disorder as Comorbidity with Sjögren’s Syndrome: What Can We Do?

Neuropsychiatric manifestations in Sjögren’s syndrome are common and can occur not only during its course, but also at the onset of the disease. Depression and anxiety were the most frequently described symptoms. However, the association with bipolar disorder seems to be rare and not well documented. This case report presents a patient with bipolar disorder as comorbidity with Sjögren’s syndrome, suggesting that bipolar disorder could be associated with this autoimmune disease, which could lead to delaying diagnosis and treatment. A better analysis of the clinical background should be done by psychiatrists so to help early diagnosis and adapting prescription. Corticosteroids indicated in Sjögren’s syndrome should be prescribed with caution in bipolar disorder.</jats:p

Radiothérapie conformationnelle du cancer de la prostate non métastatique : Experience du service de radiothérapie de l’EHS en Oncologie Emir Abdelkader d’Oran

Introduction - Le cancer de la prostate est devenu au cours de ces dernières décennies un véritable problème de santé publique, par sa fréquence et sa gravité. La radiothérapie conformationnelle constitue aujourd’hui la technique standard dansl’irradiation des cancers non métastatiques de la prostate en raison du bénéfice apporté en termes de tolérance et de contrôle de la maladie par rapport à une radiothérapie conventionnelle 2D. L’objectif de notre travail est d’étudier la survie sans rechute biochimique et la survie globale des patients atteints d’un cancer non métastatique de la prostate, traités au service de radiothérapie de l’EHS en oncologie « Emir Abdelkader » d’Oran, durant la période de juin 2010 à décembre 2014.Patients et méthodes - Il s’agit d’une étude prospective de type descriptif. Au cours de la période de l’étude, quatre-vingt-dix patients (n=90) atteints d’un cancer de la prostate non métastatique traités par radiothérapie conformationnelle ont été colligés.Résultats - L’âge moyen de de nos patients était de 66,3 ans. Le cancer de la prostate était diagnostiqué à un stade localement avancé et/ou localisé à haut risque selon la classification de D’AMICO chez 80% des cas. La radiothérapie était exclusive chez 80 patients, postopératoire immédiate chez cinq patients et de rattrapage chez cinq cas. Une hormonothérapie était associée à la radiothérapie chez la majorité des patients soit 94,4% des cas. Avec un suivi médian de 31 mois; la probabilité de survie sans rechutes biochimiques est de 64% alors que la survie globale est anestimée à 93,7%.Conclusion - Dans notre série, le cancer de la prostate est diagnostiqué à un stade avancé de la maladie, chez une population relativement jeune. La radiothérapie conformationnelle représente une réelle avancée dans le traitement du cancer de la prostate, tant sur le plan de la tolérance qu’en termes d’efficacité. Un suivi plus long et un recrutement plus important de patients est nécessaire pour valider les résultats obtenus.</jats:p
