Syndrome métabolique, diabète sucré et vulnérabilité: une approche "syndémique" de la maladie chronique [Metabolic syndrome, diabetes mellitus and vulnerability: a syndemic approach of chronic diseases].

The pandemic metabolic syndrome is generally attributed to our lifestyle. The current therapeutic strategies are centered on the behavioral changes and pharmacotherapy. A deeply analysis reveals the importance of the socio-cultural determinants with a "dose-responses effect according to the socio-economic level. The "syndemic" theory, which puts at the same level the socio-cultural environment, the behaviors and biomedecine, suggests a more holistic approach. This theory suggests introducing other partners of care, such cultural-mediators and welfare workers trained in the care, to have finally an approach centered on the roots of the causes. The healthcare networks centered on the management of the costs of health should not forget the socio-cultural dimension, unless wanting to select the good cases.

Des céphalées, cinq avis spécialisés: les pièges diagnostiques pour la maladie de Horton [Headaches, five expert opinions: the pitfalls involved in the diagnosis of giant cell arteritis].

Giant cell arteritis (GCA) (or Horton's disease) is a systemic disease affecting the vessels of medium and large sizes. The incidence increases with age (the disease develops rarely before age 50) and the etiology remains unknown. Clinical manifestations may vary (including asthenia, temporal headache, visual disturbances, etc.) and GCA can potentially lead to dramatic consequences (permanent loss of vision). Although some anomalies in the investigations may help in the diagnosis of GCA, research and confirmation of the diagnosis of GCA may be difficult, especially when the symptoms presented by patients are spread out in time and appear to be nonspecific at first.

La maladie du poumon de fermier : apports de la médecine du travail

- La maladie du poumon de fermier est une affection immunologique secondaire à l'inhalation de poussières antigéniques provenant de microorganismes qui colonisent le foin moisi. - Sa prévalence parmi la population d'agriculteurs varie de 0,4 à 5% selon les pays. - Les critères diagnostiques comprennent une anamnèse d'exposition au foin, une dyspnée d'effort, l'auscultation de râles inspiratoires et une lymphocytose alvéolaire. - La prise en charge de l'agriculteur atteint nécessite la mise en place de mesures professionnelles préventives comprenant le réaménagement de sa place de travail, le changement des habitudes de travail et le port d'un masque de protection respiratoire. Ces mesures permettent à l'agriculteur de poursuivre son activité dans la plupart des cas. - En Suisse, la maladie du poumon de fermier est une maladie professionnelle à déclarer à l'assurance accident.

Insuffisance rénale severe sur maladie des emboles de cholestérol: controverses thérapeutiques revisitées [Severe renal insufficiency secondary to renal cholesterol emboli: therapeutical options revisited]

Disseminated cholesterol crystal embolism is observed in elderly men with severe atherosclerosis. This syndrome may be triggered by arterial catheterizations, major vascular surgery, thrombolytic and/or anticoagulation treatment. Cutaneous signs, subacute renal insufficiency, a marked inflammatory syndrome and eosinophilia are common. Immunologic testing is normal except for hypocomplementaemia. The diagnosis may be confirmed by biopsy (skin, gastrointestinal or renal), and/or by a fundoscopic examination. The treatment consists in withdrawing all form of anticoagulation, proscribing vascular surgery and arterial catheterization, prescribing aspirin and statins, and controlling arterial blood pressure. Corticosteroids may be given in refractory cases. The prognosis of cholesterol crystal embolism is poor but may be improved by statins.
