De nombreuses maladies métaboliques peuvent atteindre la cheville et le tarse postérieur. Dans la phase aiguë, la goutte peut toucher l'arrière-pied, la cheville, le médio-tarse ou le tendon calcanéen. Une rougeur intense des tissus souscutanés du dos du pied peut être en rapport avec une inflammation liée à des microtophus sous-cutanés. Un diagnostic de certitude se fait par la mise en évidence de cristaux d'urate de sodium dans le liquide de ponction articulaire ou dans les tissus. L'imagerie par tomodensitométrie ou par échographie peut orienter de façon pratiquement certaine le diagnostic. Le traitement de la goutte de l'arrière-pied fait appel aux antiinflammatoires, aux anti-inflammatoires non stéroïdiens (AINS) et à la colchicine. Dans la phase chronique, un traitement hypo-uricémiant au long terme est à instaurer. L'hémochromatose se manifeste principalement sous forme d'une arthrose, liée souvent à une chondrocalcinose de la cheville et du tarse postérieur. L'enthésopathie hyperostosante diffuse peut causer des talalgies ou des douleurs du fascia plantaire liées à des exostoses. L'hypercholestérolémie familiale provoque souvent des xanthomes tendineux des tendons calcanéens. Des calcifications apatitiques de la région du talon peuvent s'observer, notamment chez des patients en hémodialyse chronique. Numerous metabolic diseases can affect the ankle and the hind-foot. In the acute phase, gout can affect the rear of the foot, the ankle, the mid-foot and the calcaneal (Achilles) tendon. Intense redness of the subcutaneous tissue of the back of the foot can be present in conjunction with inflammation associated with subcutaneous micro-tophaceous deposits. A definitive diagnosis is made by confirming the existence of sodium urate crystals in joint puncture fluid or in tissue. CT scan or ultrasonography images can also be used to provide a fairly definitive diagnosis. Treatment of gout of the rear of the foot requires the use of anti-inflammatory medication, NSAIDs and colchicine. In the chronic phase, long-term hypouricemic therapy is to be used. Haemochromatosis mainly shows in the form of arthritis, often associated with chondrocalcinosis of the ankle and hind-foot. A diffuse hyperostosis enthesopathy can cause talalgia or pain to the plantar fascia associated with exostoses. Familial hypercholesterolaemia often leads to tendinous xanthoma on the calcaneal tendons. Apatitic calcifications to the heel can also be observed, especially undergoing chronic haemodialysis.

Ce document présente un plan de prévention pour le Canton de Vaud (version octobre 2007). Ce plan concentre ses efforts sur la prévention de quelques maladies (infarctus du myocarde, accident vasculaire cérébral, diabète, cancer colorectal, cancer du sein, cancer du poumon, dépression, fracture ostéoporotique), à l'aide d'un nombre restreint d'interventions (améliorer l'alimentation et augmenter l'activité physique, lutte contre le tabagisme, prévention primaire et secondaire de la maladie athéromateuse, prévention secondaire du cancer colorectal, prévention secondaire du cancer du sein, prévention secondaire de la dépression). Après la présentation de quelques enjeux de ce plan, le rapport conclut sur trois recommandations portant sur les structures de la prévention des maladies et de promotion de la santé, le monitorage des activités de prévention des maladies et de promotion de la santé et enfin sur le mandat et l'organisation de la Commission cantonale de prévention.

Autoimmune glomerulopathies are an important cause of chronic kidney disease. Conventional treatments based on steroids, antiproliferative and cytotoxic agents are efficacious, but highly toxic. Because of their central role in the pathogenesis of autoimmunity, B cells have become an attractive therapeutic target. Rituximab is a monoclonal antibody directed against CD20 expressed on the surface of B cells, inducing profound depletion of B cells in the peripheral blood. In spite of encouraging results regarding the off-label use of Rituximab in membranous nephropathy, systemic lupus erythematosus and small vessel vasculitis, controlled, long-term data, and data with specific renal endpoints are currently lacking.

Controversies regarding the pathogenesis of cardiovascular diseases in HIV patients Since the introduction of HAART (Highly active anti-retroviral therapy), the incidence of cardiovascular events has risen in patients infected with HIV. This development is mainly due to the increased survival in these patients. Nonetheless, the pathogenic effects of HIV on the principal components of haemostasis (endothelium, platelets and the clotting cascade) are the subject of numerous ongoing research studies, and are becoming an argument for starting HAART or for modifying the components of an established therapy. The aim of this article is to raise clinician awareness regarding the issue of cardiovascular disease in the HIV-infected patient.

The increasing popularity of evidence-based practice (EBP) requires that nurses take a stand regarding this type of practice. This positioning rests on knowledge of EBP, however this notion varies by discipline and many definitions exist even within the nursing discipline. An improved understanding of the basic tenets of this type of practice is thus essential. This first, of a series of two articles describes the origin of EBP as well as various definitions, it also presents the major criticisms raised and takes a look at the impact of the increased tendency towards EBP on professional practice.
