Evaluation du Cursus Romand de Médecine de Famille (CRMF)

Le Cursus Romand de Médecine de Famille, appelé jusqu'en 2013 « Cursus Romand de Médecine Générale (CRMG), est né de la convergence de deux dynamiques. La première était locale : elle se situait autour du canton de Vaud avec le programme de formation postgraduée en médecine générale initié dans ce canton en 1999 sous l'impulsion du Dr. Fréchelin, du Prof. Pécoud et du Dr. Pilet. L'idée de départ de ce cursus strictement vaudois était de développer un programme de formation postgraduée permettant d'aider les médecins assistants à se former, mais également à promouvoir la médecine de famille et à créer une identité professionnelle forte. La seconde dynamique était politique : en 2005, lors d'une conférence de presse, la CDS annonce publiquement qu'une pénurie de médecins menace la Suisse. Parallèlement, le groupe de médecins ayant lancé le cursus Vaudois envisageait également d'étendre le territoire de la formation postgraduée de médecine générale, estimant que la formation postgrade des médecins de famille ne devait pas se cantonner aux cantons universitaires.

Neuropathologie et pathologie moléculaire des gliomes [Neuropathology and molecular pathology of gliomas]

Gliomas are the most frequent primary brain tumours. The WHO classification is essentially based on histological and immunohistochemical criteria. More recently multiple cytogenetic and molecular alterations associated with initiation and progression have been shown and the genetic profiles of tumour entities have been incorporated in the WHO classifiacation. Molecular testing of the MGMT promotor methylation in glioblastoma, predictive for the response to combined radio-/chimiothérapie, and the LOH 1p/19q in oligodendroglial tumours, as prognostic factor supplements the histopathological diagnosis. In the near futur array-based profiling techniques will contribute to a refinement of glioma classification and identify targets for more individualized glioma therapies.

Mise en place d'un cathéter veineux central chez l'adulte. 2. Technique détaillée [The central vein catheterization. 2. Procedure, step by step]

La pose d'un cathéter veineux central peut se faire par plusieurs abords. La connaissance de l'anatomie, du matériel, la maîtrise des détails de la procédure pour chaque type d'abord et une attention particulière à l'asepsie sont des prérequis importants pour limiter les risques de complications et pour donner une information complète et exhaustive au patient. Cet article peut être utilisé comme base pour le développement d'une check-list, utile pour les médecins qui doivent procéder à la pose d'un cathéter veineux central mais qui ne possèdent pas encore une maîtrise du geste. Several approaches exist for central vein catheterization. Mastery of the various steps of this procedure and understanding of the basics of asepsis are critical to prevent any complication. They also built the basis for an exhaustive communication with the patient, to obtain an informed consent. This article can in addition be used to develop a checklist in order to (self-)assess competence in procedural skills

Cercles de qualité médecins-pharmaciens, pour une responsabilité partagée de la liberté de prescription [Physicians-pharmacists quality circles: shared responsibility of the freedom of prescription].

Physicians-pharmacists quality circles (PPQCs) were introduced in 1997-98 by visionary healthcare practitioners of the French-speaking part of Switzerland with the aim to improve the quality of drug prescription. Indeed the challenge is to manage the 7917 brand names of the Swiss drug market (2010), including 19793 different dosages, galenic formulations and packaging. The impact of these PPQCs on the containment of drug costs and on drug prescribing profiles has been demonstrated and has led to their spread throughout Switzerland. PPQCs provide clear educational benefits and have thus been accredited by various continuous education bodies. In this article, participating physicians and pharmacists share their vision and illustrate how they work and influence the safety and efficiency of drug prescription, a routine process complex enough to warrant sharing of its burden in a constructive interdisciplinary collaboration.

Aider les étudiants en médecine à approcher la mort [Helping medical students to approach death].

A project recently launched by the Faculty of biology and medicine of Lausanne introduces the approach of facing death during both the dissection and the course of clinical activities. Existential questions relating to mortality are bound to arise sooner or later during the course of the study. For the sake of humanized clinical practice, these questions must be confronted. In response to a request by a student association, an accompanying curriculum with active student's contribution through encounters with death in anatomy and clinical situations was created in Lausanne. Students will benefit from this new program throughout their curriculum. This program is the first of its kind in Switzerland.

Traitement de l'hypertension artérielle chez le sujet obèse [Treatment of hypertension in obese patients].

Prevalence of obesity and hypertension has increased these last decades. Around 60 to 70% of the incidence of hypertension is related to obesity. The relationship between obesity and hypertension is now well established. The sympathetic nervous system and the renin-angiotensin-aldosterone (RAA) system are activated in obese patients, mostly by insulin, and predispose the kidney to reabsorb sodium and water. In obese patients with hypertension, it is recommended to target a blood pressure < 140/90 mmHg. Lifestyle changes (weight loss, physical activity, low-salt diets) are useful to decrease blood pressure but are difficult to maintain in the long-term. When drugs are necessary, drugs that are metabolically neutral should be used, and often need to be combined to other drug classes in order to achieve blood pressure target.

Accès sans prescription aux statines: bénéfique ou délétère. [Over-the-counter statins: benefit or harmful?]

Making statin available over the counter is one of the measures proposed to correct its underuse. Since May 2004, simvastatin 10 mg is sold over the counter in Great Britain. But uncertainties persist concerning the efficacy of statin in primary prevention and at a 10 mg dose. Finally, there is a risk of side effects and drug interactions. Beyond the correction of statin underuse and the hope of coronary heart disease mortality reduction, the British decision highlighted the will to give individuals a sense of responsibility concerning their health and its financial cost. Anyway, the benefit of switching statin from prescription to over the counter should be experimentally evaluated before its introduction.

Fièvre, adénopathie: une situation clinique de toxoplasmose aiguë chez une patiente immunocompétente [Fever and lymphadenopathy: acute toxoplasmosis in an immunocompetent patient].

Toxoplasmosis is an infectious disease caused by the intracellular parasite Toxoplasma gondii. In Switzerland about a third of the population has antibodies against this pathogen and has thus already been in contact with the parasite or has contracted the disease. Immunocompetent patients are usually asymptomatic (80-90%) during primary infection. The most common symptom is neck or occipital lymphadenopathy. Serology is the diagnostic gold standard in immunocompetent individuals. The presence of IgM antibodies is however not sufficient to make a definite diagnosis of acute toxoplasmosis. Distinction between acute and chronic toxoplasmosis requires additional serological tests (IgG avidity test). If required, the most used and probably most effective treatment is the combination of pyrimethamine and sulfadiazine, with folinic acid.

Sédation par propofol administrée par un non-anesthésiste pour l'endoscopie digestive [Administration of propofol by non-anesthesiologists for digestive endoscopy].

Propofol is progressively replacing benzodiazepines for sedation during endoscopy, even when the sedation is administered by non-anesthesiologists. Propofol ensures a more rapid induction of sedation and recovery and, in certain conditions, higher patient satisfaction and improved quality of endoscopic examination. Specific training is required to use this drug. Patients at risk of complications should be identified before the endoscopy to optimize patient management with an anesthesiologist. After sedation, psychomotor recovery is faster with propofol compared to traditional sedation agents but tasks requiring particular attention (eg, driving) should be avoided. It is important to advise patients of these restrictions in advance.
