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.

Neuropsychiatrie de l'épilepsie, des accidents vasculaires cérébraux, de la maladie de Parkinson et de la sclérose en plaques [Neuropsychiatry of epilepsy, stroke, Parkinson's disease and multiple sclerosis]

L'étude du comportement au sens large fait partie intégrante de l'examen neurologique classique. Cet article présente une revue des manifestations comportementales et thymiques dans l'épilepsie, l'accident vasculaire cérébral, la maladie de Parkinson et la sclérose en plaques. The assessement of behavior is common part of the neurological examination. This article reviews the behavioral and mood manifestations in four classical syndroms: Epilepsy, stroke, Parkinson's disease and multiple sclerosis

Prévalence des troubles de l'humeur dans la maladie de Parkinson traitée par stimulation cérébrale profonde [Prevalence of mood disorders in Parkinson's disease patients treated with subthalamic nucleus deep brain stimulation].

Subthalamic nucleus deep brain stimulation (STN-DBS) is a recognized treatment for advanced and severe forms of Parkinson's Disease. The procedure improves motor signs and often allows a reduction of the medication. The impact of the procedure on cognitive and neuropsychiatric signs of the disease is more debated and there is an international consensus for the need of a multidisciplinary evaluation of patients undergoing such programs, including a neuropsychiatric assessment. We present a review of the literature as well as the experience at our centre focused on the short and long term outcome on mood following STN-DBS.

La maladie de Still de l'adulte [Adult-onset Still's disease]

La maladie de Still de l'adulte reste un diagnostic souvent évoqué, mais difficile à poser en l'absence d'anomalie clinique ou de laboratoire pathognomonique. Il est encore un diagnostic d'exclusion et la difficulté réside dans l'utilisation rationnelle et adéquate de ces tests d'exclusion. Le traitement reste quant à lui pragmatique, basé sur une analyse de situation et une définition claire des objectifs. Finalement, si les traitements biologiques semblent efficaces, ils restent réservés aux cas résistant aux traitements conventionnels ou corticodépendants. If the diagnosis of Adult-onset Still disease is often entertained, the disease remains difficult to diagnose in the absence of any specific clinical or laboratory anomaly. Diagnosis is still a diagnosis of exclusion, and the difficulty rests in the rational and appropriate use of those exclusion tests. Treatment is pragmatic, based on an analysis of the situation and a clear definition of the objectives. Finally, if biological treatments appear efficient, they should be reserved for patients resistant to conventional therapy or corticodependant

Recommandations pour la prise en charge de la forme systémique l'arthrite juvénile idiopathique (maladie de Still) [Guidelines for diagnosis and treatment in systemic-onset juvenile idiopathic arthritis.]

A guideline group of pediatric rheumatologist experts elaborated guidelines related to the management of idiopathic juvenile arthritis in association with the Haute Autorité de Santé (HAS). A systematic search of the literature published between 1998 and August 2008 and indexed in Pubmed was undertaken. Here, we present the guidelines for diagnosis and treatment in systemic-onset juvenile idiopathic arthritis.

S. P. Huntington : identitats i geopolítica

Aquest treball té com a propòsit esbrinar quina política internacional legitima S. P. Huntington, i quin paper hi adjudica als Estats Units. En aquest sentit, s'analitza el contingut de la teoria del "xoc de civilitzacions" i es treuen conclusions a partir de l'associació que realitza el politòleg nord-americà entre política internacional i les identitats cultural i religiosa en un món que ell considera marcadament hobbesià o d'esperit agonista.

Peut-on traiter la maladie d'Alzheimer [Is there a treatment for Alzheimer's disease?].

Alzheimer's disease is a frequent neurodegenerative disease, which affects more than one third of elderly persons over 80 years. No curative treatment is currently available for this disease, but symptomatic treatments have produced significant improvements in patients' condition. Cholinesterase inhibitors should be prescribed for early and moderate stages and memantine for more severe stages of the disease. These drugs have an impact on cognitive performances, may delay functional decline and improve behaviour disturbances. From a preventive perspective, evidence of benefit from early management of vascular risk factors is accumulating. In the near future, the improved comprehension of the underlying mechanisms of Alzheimer's disease will hopefully bring new treatments, thats will delay or modify its course.

Hypertension artérielle pulmonaire primitive et maladie de Basedow [Primary pulmonary hypertension arterial and Basedow disease].

We report a case of a fifty year old woman with Graves' disease with positive AntiTPO antibodies and positive AntiTSH receptor antibodies, who was hospitalized with a right cardiac failure. A pulmonary hypertension was discovered on echocardiography. After adequate antithyroid therapy, the right cardiac failure regressed rapidly and pulmonary pressure normalised. An autoimmune process has often been proposed to explain the association between pulmonary hypertension and hyperthyroidism. We report the arguments supporting this autoimmune etiopathogenesis. We also discuss an other hypothesis based on a direct effect of thyroid hormones on the pulmonary circulation and the effects of high cardiac output associated with hyperthyroidism.
