Vers une sociolinguistique médicale : une approche des objets de langage dans le contexte de la médecine

L'interaction soignant-soigné, dans ses aspects relationnel et communicationnel, a fait l'objet depuis les années 1970 de nombreuses études, inscrites dans une pluralité d'approches théoriques et méthodologiques. L'approche de la sociolinguistique de type médical, dans laquelle s'insère le présent travail de thèse, s'est développée dans le contexte même de ces études. Ce travail s'articule autour de trois sujets de recherche permettant d'illustrer, d'éclairer ainsi que de définir l'approche spécifique de la sociolinguistique médicale et traduisant, par ailleurs, certaines des questions relatives au développement de cette sociolinguistique, qui relève des sciences de la communication et des sciences humaines en médecine. Les deux premiers sujets de recherche se focalisent sur le processus d'échange d'information, central dans l'interaction médicale. Ils portent, pour l'un, sur un format de question spécifique utilisé par des étudiants en médecine dans le cadre d'entretiens avec patients simulés centrés sur l'annonce de mauvaises nouvelles et, pour l'autre, sur la(es) définition(s) d'une unité lexicale attestée dans le contexte communicationnel du VIH/sida. Le troisième sujet de recherche, en corrélation avec les deux autres, traite des défis qui se posent aux chercheurs-sociolinguistes relativement à l'étude et à la production de savoirs sur des questions liées à la santé et à la maladie. - Since the 1970's, many studies, following various theoretical and methodological approaches, have investigated - from a relational and communication point of view - the interaction between health care professionals and patients. The approach of the medical sociolinguistics, on which this PhD thesis is based, has been developed in the context of these studies. This PhD thesis is centred on three research topics illustrating and revealing the specific approach of the medical sociolinguistics and reflecting, as regards the third research topic, on particular issues related to the development of this discipline belonging to both communication sciences and medical humanities. The first two research topics focus on the information sharing process, a main phase and purpose of the medical interaction. They address (i) a particular question design used by medical students with simulated patients in breaking bad news interviews, and (ii) the meaning of a lexical unit used in the HIV/AIDS communication context. The third topic, related with the two other, focuses on the challenges faced by medical sociolinguists while producing knowledge and investigating health- and disease-related issues.

Traitements des facteurs de risque cardiovasculaire et dépistage de la maladie coronarienne dans le diabète de type 2 [Treatments for cardiovascular risk factors and screening for coronary artery disease in type 2 diabetes mellitus]

The recent ACCORD and DIAD studies revealed results which could modify treatments and the screening of diabetes vascular complications. Indeed, ACCORD shows no benefit on the prevention of diabetes vascular complications by aggressive treatment of hypertension or the combined treatment of the dyslipidemia. The intensive treatment of the blood glucose, if associated with severe hypoglycemias, increases mortality. DIAD revealed 20% of silent myocardial ischaemia in diabetic patients but no beneficial effect on the cardiovascular mortality. A careful reading of these studies in the light of long term studies such as UKPDS and STENO reveals that these negative results are generated by a too short follow-up and too aggressive objectives. The long term studies reveal that more realistic objectives remain beneficial.

Carie du biberon: un caillou dans la chaussure de la santé [The impact of childhood caries].

The early childhood caries affect primary dentition before the eruption of the permanent teeth. It is set to extended use of a bottle containing fermentable carbohydrates. The early childhood caries is not only a dental disease: it is a social, cultural and behavioral condition that reflects the practices and beliefs around the child. Swiss data indicate that in aged 2 children, one of for could be affected by this devastating oral disease, mainly in vulnerable populations. The primary care physician has an important role in the screening of preschool children, in determining the risk level of the child for early childhood caries. Physicians can advise families, especially pregnant women, about preventive measures and behavior, leading to a dramatic drop of early childhood caries prevalence.

Détection santé : plusieurs failles dans la gestion des absences grèvent le processus

Une recherche du Fonds national et de la SUVA [sur la réinsertion professionnelle des travailleurs absents en raison de troubles musculosquelettiques dorsaux] dévoile plusieurs failles dans la gestion des absences. Ce qui freine la détection puis la réinsertion de collaborateurs souffrant de mal de dos. La récolte des données est souvent incomplète et la coordination RH-managers-partenaires externes est lacunaire. Enquête et quelques pistes pour corriger le tir. [Ed.]

Le point sur l'ergométrie en 2012 dans le diagnostic de la maladie coronarienne.

Background In patients presenting with acute cardiac symptoms, abnormal ECG and raised troponin, myocarditis may be suspected after normal angiography. Aims To analyse cardiac magnetic resonance (CMR) findings in patients with a provisional diagnosis of acute coronary syndrome (ACS) in whom acute myocarditis was subsequently considered more likely. Methods and results 79 patients referred for CMR following an admission with presumed ACS and raised serum troponin in whom no culprit lesion was detected were studied. 13% had unrecognised myocardial infarction and 6% takotsubo cardiomyopathy. The remainder (81%) were diagnosed with myocarditis. Mean age was 45615 years and 70% were male. Left ventricular ejection fraction (EF) was 58610%; myocardial oedema was detected in 58%. A myocarditic pattern of late gadolinium enhancement (LGE) was detected in 92%. Abnormalities were detected more frequently in scans performed within 2 weeks of symptom onset: oedema in 81% vs 11% (p<0.0005), and LGE in 100% vs 76% (p<0.005). In 20 patients with both an acute (<2 weeks) and convalescent scan (>3 weeks), oedema decreased from 84% to 39% (p<0.01) and LGE from 5.6 to 3.0 segments (p¼0.005). Three patients presented with sustained ventricular tachycardia, another died suddenly 4 days after admission and one resuscitated 7 weeks following presentation. All 5 patients had preserved EF. Conclusions Our study emphasises the importance of access to CMR for heart attack centres. If myocarditis is suspected, CMR scanning should be performed within 14 days. Myocarditis should not be regarded as benign, even when EF is preserved.
