Traitement et prévention de la maladie thromboembolique veineuse: quoi de neuf ? [Treatment and prevention of venous thromboembolic disease: what's new?]

Venous thromboembolic (VTE) disease is frequent and questions regarding its treatment or prevention are numerous. This review is aimed at summarizing and pointing out the novelties on VTE treatment and prevention recently published in the Chest journal earlier this year (8th edition of ACCP guidelines). Generally, the aim of guidelines and of this review as well, is to offer guidance to practictioners in making the most appropriate choice for treating or preventing VTE. They are not intended for strict application and doctors will always have to decide individually case by case taking into account patients preference and the risk-benefit balance.

Epidémiologie et prévention du mélanome cutané en Suisse. [Epidemiology and prevention of melanoma in Switzerland].

[Quintessence] - L'incidence du mélanome malin augmente rapidement depuis plus de 50 ans. - La Suisse, avec 1700 nouveaux cas diagnostiqués par an, est, avec la Norvège, le pays d'Europe le plus touché par le mélanome. - Des différences régionales sont récemment apparues avec une incidence plus élevée dans les cantons romands. - Les changements observés en Suisse dans l'attitude et le comportement face au soleil sont trop récents et modestes pour influencer l'incidence. - La détection précoce effectuée depuis près de 20 ans a permis d'augmenter la survie et le taux de mélanomes fins sans toutefois altérer l'incidence des lésions épaisses. - La mortalité associée au mélanome malin a récemment diminué, d'abord chez les femmes. L'efficacité de la prévention devrait se confirmer à terme si les efforts entrepris se poursuivent. [Auteurs] [Summary] - The incidence of malignant melanoma has steadily increased in Caucasian populations over the last 50 years. - With some 1700 new cases per year, Switzerland has, with Norway, the highest rate of melanoma in Europe. - Regional differences within Switzerland are emerging, with a higher incidence in western (French-speaking) cantons. - Observed changes in sun protection attitudes and knowledge in the Swiss population have yet to impact on the incidence trend. - Early detection, as pursued since the mid-1980s in Switzerland, has led to a substantial increase in survival and rates of thin melanoma, without major change in rates of thick melanoma. - Mortality from melanoma has recently decreased, initially in women. The effectiveness of prevention campaigns should eventually be confirmed if current efforts persist. [Authors]

Calcifications vasculaires et déficit en vitamine K: un facteur de risque modifiable dans l'insuffisance rénale chronique [Vascular calcifications and vitamin K deficiency: a modifiable risk factor in chronic kidney disease].

The mechanisms of vascular calcifications in chronic renal failure are complex. Apart for clotting factors, vitamin K-dependent proteins include matrix Gla protein. Glutamic acid residues in matrix Gla protein are carboxylated by vitamin K-dependent gamma-carboxylase, which enables it to inhibit calcification. The purpose of this review is to discuss available evidence implicating vitamin K as a modifiable risk factor in the pathogenesis of vascular calcification in renal diseases.

Enseignement de recommandations pour la pratique: la prévention et le dépistage [Teaching practice recommendations: prevention and screening].

The aim of this article is to provide guidance to family doctors on how to tutor students about effective screening and primary prevention. Family doctors know their patients and adapt national and international guidelines to their specific context, risk profile, sex and age as well as to the prevalence of the disorders under consideration. Three cases are presented to illustrate guideline use according to the level of evidence (for a 19-year-old man, a 60-year-old woman, and an 80-year-old man). A particular strength of family medicine is that doctors see their patients over the years. Thus they can progressively go through the various prevention strategies, screening, counselling and immunisation, accompanying their patients with precious advice for their health throughout their lifetime.

Insuffisance corticosurrénalienne précipitée par un traitement de lévothyroxine [Adrenal insufficiency caused by treatment with levothyroxine]

Primary adrenal insufficiency is a rare disease. Its diagnosis remains a clinical challenge since the signs and symptoms of the disease are insidious in onset and non specific in nature. A case report of Addison's crisis induced by levothyroxine substitution therapy is described. This clinical case is discussed in details with a special emphasis to the published literature regarding the strategy of diagnosis and the specific therapy of primary adrenal insufficiency.

Un projet multicentrique suisse pour améliorer la prévention et la récidive après un syndrome coronarien aigu [A Swiss multicentric project to improve the prevention of cardiovascular event recurrence after acute coronary syndromes].

Recurrence of cardiovascular events and mortality remain high after acute coronary syndromes. A Swiss multicentric study, "Inflammation and acute coronary syndromes (ACS)--Novel strategies for prevention and clinical managements", is currently underway with the support of the Swiss National Science Foundation. The study includes a clinical research subproject of which the aim is to assess the impact of the ELIPS program (multi-dimEnsionaL prevention Program after acute coronary Syndrome) on the recurrence of cardiovascular events after an ACS. The basic research sub-projects aim to investigate novel cardiovascular risk biomarkers and genetic determinants of recurrence and to study the role of stem cells after an ACS. Another sub-project will evaluate intracoronary imaging techniques and the efficacy of different types of stents.

Maladies cardiovasculaires: une cible de prévention pour contrecarrer les effets de l'évolution démographique [Cardiovascular diseases: a target for prevention to thwart the effects of population aging]

The prevalence of cardiovascular diseases is high in the old age. These conditions have a negative impact on the quality of life and are associated with a high risk of disability. A marked increase in the number of affected individuals is likely, in coming decades, with population aging. Primary cardiovascular prevention, but also an early recognition of subclinical heart diseases and secondary and tertiary prevention will be of up most importance for individuals (quality of life) and for societies (burden of functional impairments) as the baby-boom generation reaches retirement age.

Diabète et insuffisance rénate terminate. Evolution en huit ans dans le canton de Vaud [Diabetes and end stage renal disease. Eight year progression in the Canton de Vaud, Switzerland].

Diabetic nephropathy is the first cause of endstage renal disease. The demographic expansion, the increase in the incidence of diabetes and the prolonged survival rates explain the steep increase observed these last 30 years. In the United States, improved treatment has brought to a decline in the incidence of end-stage renal disease in the diabetic population since the mid nineties. We examined the change in prevalence of diabetics on dialysis from 2001 and 2009 in the Canton de Vaud, Switzerland. The prevalence of diabetics on dialysis increased from 18% to 31% in dialysis centers and increased from 1.1/1000 to 1.9/1000 in the diabetic population. These are strong indicators that efforts are needed to improve the renal outcome of patients with diabetic nephropathy.
