Evaluation de la campagne Break The Chain 2012

L'Office fédéral de la santé publique (OFSP) a mandaté l'Institut universitaire de médecine sociale et préventive (IUMSP) afin d'évaluer la campagne nationale « Break The Chain » réalisée en avril 2012. Il s'agit d'une campagne de prévention du VIH/sida s'adressant exclusivement aux hommes ayant des rapports sexuels avec des hommes (HSH). Elle a été mise en oeuvre par le Checkpoint Zürich et le Checkpoint Genève avec l'appui de l'Aide suisse contre le sida (ASS) sur mandat de l'OFSP.

The joint influence of gender and amount of smoking on weight gain one year after smoking cessation.

Weight gain is often associated with smoking cessation and may discourage smokers from quitting. This study estimated the weight gained one year after smoking cessation and examined the risk factors associated with weight gain in order to identify socio-demographic groups at higher risk of increased weight after quitting. We analyzed data from 750 adults in two randomized controlled studies that included smokers motivated to quit and found a gradient in weight gain according to the actual duration of abstinence during follow-up. Subjects who were abstinent for at least 40 weeks gained 4.6 kg (SD = 3.8) on average, compared to 1.2 kg (SD = 2.6) for those who were abstinent less than 20 weeks during the 1-year follow-up. Considering the duration of abstinence as an exposure variable, we found an age effect and a significant interaction between sex and the amount of smoking before quitting: younger subjects gained more weight than older subjects; among light smokers, men gained more weight on average than women one year after quitting, while the opposite was observed among heavy smokers. Young women smoking heavily at baseline had the highest risk of weight gain after quitting.

Traitement de la schistosomiase à S. mansoni : quelle alternative au praziquantel ?

Les schistosomiases sont des maladies parasitaires causées par des helminthes du genre Schistosoma (S.) qui touchent 200 millions de personnes dans le monde, mais restent rares chez le voyageur. Contrairement à S. heamatobium, agent de la bilharziose urinaire, S. mansoni, présent en Afrique subsaharienne, en Egypte ainsi qu'aux Antilles, au Surinam et dans le nordest du Brésil, est responsable des formes hépato-intestinales de la maladie. Les larves, vivant en eaux douces contaminées par des selles infectées, peuvent pénétrer la peau des baigneurs sans que l'individu ne s'en rende compte. Les parasites adultes s'établissent dans le système veineux digestif où ils se reproduisent et excrètent des oeufs qui migreront dans la lumière intestinale. Cette revue systématique évalue les effets des médicaments antibilharziens, utilisés seuls ou en association, pour traiter l'infection à S. mansoni.

Suivi neurodéveloppemental de l'enfant né prématuré dans l'Arc lémanique [Neurodevelopmental follow-up of premature children in Lausanne and Geneva].

Preterm children born before 32 weeks of gestation represent 1% of the annual births in Switzerland, and are the most at risk of neurodevelopmental disabilities. A neurological surveillance is thus implemented in the neonatal units, and multidisciplinary neurodevelopmental follow-up is offered to all our preterm patients. The follow-up clinics of the University hospitals in Lausanne and Geneva follow the Swiss guidelines for follow-up. An extended history and neurological examination is taken at each appointment, and a standardized test of development is performed. These examinations, which take place between the ages of 3 months and 9 years old, allow the early identification and treatment of developmental disorders frequent in this population, such as motor, cognitive or behavioral disorders, as well as the monitoring of the quality of neonatal care.

Surveillance active du cancer de la prostate [Active surveillance in prostate cancer].

Active surveillance in prostate cancer The spread of PSA in the screening of prostate cancer has almost doubled the incidence of this disease in the last twenty years. An improved understanding of the natural history of this cancer allows for risk stratification of the disease and to better predict insignificant prostate cancer. Active surveillance has recently been proposed as a new option to delay or avoid a radical treatment for patients with low-risk disease. The principle, results and future perspectives of this treatment modality are discussed in this review.

Programme cantonal Diabète: bilan de la première phase du programme (2010-2011) et construction d'une théorie d'action.

Le Programme cantonal diabète (PCD) du canton de Vaud a pour objectifs de réduire durablement l'impact du diabète sur la population vaudoise. Il a été élaboré à l'initiative du Service de la santé publique du canton de Vaud et la stratégie du programme a été construite sur la base des propositions de plusieurs groupes de travail. Ce programme inclut divers projets complémentaires qui ont été progressivement mis sur pied à partir de 2010. 2012 marque la fin de la première phase du programme et une évaluation-bilan du programme est demandée. Cette évaluation-bilan fait suite à une première phase de travaux qui ont consisté en une évaluation de l'évaluabilité du programme. Les résultats de cette première phase ont été délivrés en décembre 2011 au groupe de pilotage et consignés dans un rapport en février 2012. L'IUMSP propose donc pour 2012 des travaux en continuité de ce qui a été fait en 2011 et qui vont dans le sens d'un bilan critique et de propositions pour un système de monitoring à long terme du programme, comportant des indicateurs d'activité (à harmoniser lorsque c'est possible dans des projets similaires), des indicateurs de couverture et de résultats.

Enjeux ethiques de la psychiatrie sous contrainte [Ethical issues in psychiatry under coercion].

Psychiatry is now subject to two apparently contradictory movements. On the one hand, the need to respect the autonomy and rights of patients is reinforced and coercive measures are strictly defined and limited. On the other hand, security concerns in our society leads to prosecution of psychiatric disorders, especially when accompanied by behavioral problems or criminal acts. In these situations of compulsory treatment or care provided in prisons, a number of dilemmas emerge. The place of the healthcare professional in treatments ordered by the Justice and problems related to administrative detention are discussed in more detail.

Nouvelles directives assécurologiques pour la prise en charge de la chirurgie bariatrique: conséquences pratiques [New guidelines for bariatric surgery care: practical implications].

From the 1st of January 2011, new conditions have been validated in which surgery for weight loss is borne by the basic insurance. These are very significant changes compared to the old criteria. Indeed, on one hand, patients with BMI > or = 35 kg/m2 may, without age limit and in the absence of comorbidities benefit from surgery without prior request to the medical council health insurance company concerned. On the other hand, the notion of a minimum casuistry is for the first time introduced in centers performing this type of intervention. In addition, certified centers are required to follow standard procedures for the patients' teaching and follow up.

Cancer du sein chez la jeune femme: traitements adjuvants et désir de grossesse [Breast cancer in young women: adjuvant therapy and fertility]

Prognosis of breast cancer women has been dramatically improved by the adjuvant therapies. As the vast majority of patients are cured, the importance of long-term quality of life is growing. The question of the maternity is an essential concern for the young women who have to receive chemotherapy or several years of endocrine therapy. This problem is often underestimated and may lead to emotional distress, depression or anxiety. A regional multidisciplinary working group was set up in order to offer optimal information about fertility and cancer as to propose specific therapeutic reproduction options, when applicable. Specificity of the young patients' breast cancer, the treatment approaches and their impact on fertility are discussed in this paper.

Intoxication par les champignons [Mushroom poisoning].

Mushroom poisoning is a regular complaint for consultation in emergency facilities. These situations are usually benign and symptomatic treatment is sufficient. However, severe damage can occur, potentially life-threatening. We review the various syndromes associated with the toxins involved, their management and the major signs that are suggestive of serious injury and requiring hospitalization.

Lésions de surcharge chez l'enfant [Overuse injuries in children].

The physical-activity and sporting at the child and the teenager is probably, in these years 2000, in full change. In a paradoxical way, extremely sporting children or teenagers are living beside extremely sedentary school-boys, neglecting the majority of the physical-activities and preferring a home-lifestyle. In the evaluation of overload sporting lesion of at teenager, it is thus imperative to take into account not only the individual characteristics of the child: its sex, its age, its stage of growth, its psychology, the presence or not of preexistent pathologies or anatomical disorders. It is naturally necessary to wonder about the training methods of the activity, but it appears fundamental to me to evaluate the child from a sensitivo-motor point of view and this can be carried out by assessments physio-therapeutic or aptitude tests carried out by doctors of the sport.
