Apports de la médecine nucléaire en cardiologie préventive: l'exemple du syndrome métabolique [Value of nuclear medicine in preventive cardiology: the metabolic syndrome example]

Metabolic syndrome represents a grouping of risk factors closely linked to cardiovascular diseases and diabetes. At first, nuclear medicine has no direct application in cardiology at the level of primary prevention, but positron emission tomography is a non invasive imaging technique that can assess myocardial perfusion as well as the endothelium-dependent coronary vasomotion--a surrogate marker of cardiovascular event rate--thus finding an application in studying coronary physiopathology. As the prevalence of the metabolic syndrome is still unknown in Switzerland, we will estimate it from data available in the frame of a health promotion program. Based on the deleterious effect on the endothelium already observed with two components, we will estimate the number of persons at risk in Switzerland.

Les dysthyroïdies en médecine de premier recours [Thyroid dysfunction in primary care medicine].

Thyroid function tests include the measuring of the thyroid stimulating hormone (TSH) and free thyroxine (T4) in the case of abnormal TSH. These tests are frequently performed in primary care medicine since many clinical situations can be suggestive of dysthyroidism, as for example fatigue, depressive states or cardiac arthmia. In the case of subclinical thyroid dysfunction, the indications for treatment are controversial there being a lack of significant randomised studies. For primary care physicians faced with abnormal thyroid function tests we propose a diagnostic approach, clinical recommendations, and indications for referral to the specialist.

Compas : stratégies de prise en charge clinique : médecine interne générale ambulatoire

En 36 chapitres, concis et efficaces, cet ouvrage propose des repères pour la prise en charge des patients adultes en médecine générale et en médecine interne ambulatoire. Les thèmes ont été choisis en fonction des besoins exprimés par les médecins en formation. Chaque chapitre propose une stratégie diagnostique et thérapeutique dans une perspective d'usage rationnel des ressources du système de santé, en tenant compte des données les plus récentes de la médecine basée sur les preuves. Ce livre confirme que la pratique de la médecine reste un subtil assemblage des connaissances scientifiques, de l'expertise clinique et des valeurs du patient.

Se former à l'entretien motivationnel pour aider ses patients à changer: Les étudiants en médecine le confirment [Learning motivational interviewing to help patients change their health-related behaviors: medical students confirm it].

At the Lausanne University, 5th year medical students were trained in Motivational interviewing (MI). Eight hours of training improved their competence in the use of this approach. This experience supports the implementation of MI training in medical schools. Motivational interviewing allows the health professional to actively involve the patient in this behavior change process (drinking, smoking, diet, exercise, medication adherence, etc.), by encouraging reflection and reinforcing personal motivation and resources.

Acquisitions thérapeutiques en médecine ambulatoire en 2011 [2011 findings from literature on general internal ambulatory medicine].

In 2011 several articles seemed significant for the practice of general medicine. Diagnosis of hypertension needs several measurements and may need 24-hour ambulatory blood pressure monitoring. Glycosylated hemoglobin is a reliable tool to diagnose diabetes mellitus. The ABCD2 score with neurological imaging help the triage of transient ischemic attacks. Pulmonary embolism can be treated as outpatient for low risk patients. Gluten-free diet may be tried in irritable bowel syndrome. Nitrofurantoin is a reasonable alternative for simple urinary tract infection in women, but antibiotics are not needed after drainage of an uncomplicated skin abscess. Subclinical thyroid dysfunction is a risk factor of osteoporosis in older men. Sequential use of MMSE and ACE scores is a promising approach to assess medical decision-making capacity.
