Le corps, lieu de l'expérience des limites? Réflexions à partir de la littérature chrétienne antique (Ascension d'Esaïe 6 et Recconnaissances II,61-66, en écho à 2 Co 12,1-11)

(Résumé de l'ouvrage) Dans cet ouvrage réunissant théologiens et philosophes, le corps contemporain est pensé par rapport à ce qui l'excède, ce qui le met en scène, ce qui le reprend, ce qui le transforme aujourd'hui. Dans une première partie, l'ouvrage propose des éclairages sur le corps à partir de ce qui met en question sa vision strictement rationnelle. Puis, trois auteurs évoquent les différentes manières dont la Bible, la philosophie et la littérature contemporaine mettent en scène les corps. Dans une troisième partie, sont abordées des questions plus spécifiquement reliées à la tradition catholique, au christianisme primitif et à la pratique de l'ascèse. Enfin, quatre contributions explorent le défi posé par la déréalisation du corps dans nos sociétés d'aujourd'hui, avec, pour clore l'ensemble, une réflexion sur le dualisme qui traverse le questionnement sur le corps.

Testostérone et os: indications et limites [Testosterone and bone: indications and limitations].

Osteoporosis incidence increases exponentially with age in men and hypogonadism represents a risk factor. Sex steroids levels are correlated to bone mineral density and to fracture prevalence. Most studies demonstrate an improvement in bone mineral density in men with hypogonadism as a result of testosterone therapy. Nevertheless there are no data evaluating the effect of testosterone therapy on fractures in men. Approximately 20% of men older than 60 have a total testosterone level lower than the lower limit of the reference range but there is no true consensus on the definition of hypogonadism in older men. In older men we recommend to treat only if total morning testosterone levels are < 8 nmol/l or even < 6,9 nmol/l on several occasions in the absence of any reversible illness and if there is no contraindication for treatment.

Interét et limites de l'evaluation du risque de récidive d'actes illégaux dans les expertises psychiatriques [Benefits and limitation of the assessment of second offense risk in psychiatric expertise].

The legislatives evolutions imply an important recourse to the psychiatric expertise in order to evaluate the potential dangerousness of a subject. However, in spite of the development of techniques and tools for this evaluation, the dangerousness assessment of a subject is in practice extremely complex and discussed in the scientific literature. The evolution of the concept of dangerousness to the risk assessment involved a technicisation of this evaluation which should not make forget the limits of these tools and the need for restoring the subject, the meaning and the clinic in this evaluation.

Limites des procédés d'investigation de la fonction érectile dans le cadre d'expertises médicolégales [Limits of the processes of investigation of the erectile function in forensic expertises].

Résumé La responsabilité d'un expert chargé d'apprécier la capacité érectile d'un prévenu est importante, car la peine infligée par le tribunal peut dépendre de ses conclusions. Sa tâche est en plus ardue car les procédés d'investigations de la fonction érectile ont tous des limites. Malgré toutes ces limites qui sont décrites dans cet article, l'expert peut aider à la recherche de la vérité comme les auteurs le démontrent. Summary The responsability of the expert in charge to appreciate the erectile capacity of an accused is considerable, as the sentence inflicted by the Tribunal could depend directly on his conclusions. His duty is harder as all the investigation procedures of the erectile functions have limits. Despite these limits, described in this article, the expert can help to discover the truth, as demonstrated by the authors.

Dégénérescence maculaire liée à l'âge exsudative: efficacité et limites des différents traitements [Exudative age-related macular degeneration: efficacy and limits of the different treatments].

Ocular neovascularizations are responsible for irreversible loss of vision in various diseases, including age-related macular degeneration. Treatments have changed greatly, and photodynamic therapy with verteporfin has come into common use. However, the visual prognosis remains poor. The recent approval of new antiangiogenic molecules such as ranibizumab and pegaptanib should allow for new therapeutical possibilities. The unapproved ophthalmological use of bevacizumab requires further studies. This paper updates what is known about old and new neovascularization treatments: their mechanism of action, their efficacy, and their toxicity. It reviews the principal clinical studies, and concludes with the recognized recommendations. For the first time, ophthalmologists can hope not only to stabilize loss of vision, but also to improve visual acuity. Complementary treatments can now be tested in associations, concomitantly or not, with the hope of improving visual results.

Laparoscopie abdominale: possibilités et limites [Abdominal laparoscopy: an update]

Laparoscopic surgery has become a standard approach for many interventions, including oncologic surgery. Laparoscopic instruments have been developed to allow advanced surgical procedure. Imaging and computer assistance in virtual reality or robotic procedure will certainly improve access to this surgery.

Indications, perspectives et limites de la stimulation électrique épidurale en cas d'artériopathie périphérique ou coronarienne [Indications, limits and future of epidural spinal cord electrical stimulation for coronary and peripheral artery disease]

The electrical stimulation of the dorsal columns of the spinal cord exerts a dual analgesic and vasodilatory effect on ischemic tissues. It is increasingly considered a valuable method to treat severe and otherwise intractable coronary and peripheral artery disease. The quality of the results depends from both a strict selection of the patients by vascular specialists and the frequency and quality of the follow-up controls. However the indications, limits, mode of action and results of spinal cord stimulation are still poorly understood. This article, based on a personal experience of 164 implantations for peripheral and coronary artery disease, aims to draw attention to this technique and to provide information on recent and future developments.
