Troubles digestifs associés aux protozoaires et aux helmintes: prise en charge par le médecin de famille [Gastrointestinal complaints associated to helminth and protozoan: management by the general practitioner].

Protozoan and helminthes are frequently associated with persistent digestive complaints, not only in returning travelers from the tropics, but also in industrialized countries. The symptoms are often more vague than those associated to bacterial or viral infections and diarrhea is not always a key feature of the clinical presentation. Three stool examinations and a full blood cells count looking for eosinophilia is the comer stone of the investigations looking for digestive parasites. This article reviews the epidemiology, clinical presentation, diagnostic and management of digestive protozoans and helminthes.

Nursing performance in the policy transfer of directly observed treatment of tuberculosis

Objective Analyzing the policy transfer of directly observed treatment of tuberculosis from the perspective of nursing. Method This is a descriptive study with qualitative approach, which had 10 nurses of the Family Health Strategy in São Paulo as subjects. The interviews were carried out between May and June 2013, and were adopted the technique of thematic content analysis and the referential of policy transfer. Results On the signification of this treatment, are related the senses of disciplinary monitoring, the bond and approximation to the context of patients’ lives. Operationally, nurses, community health agents and nursing technicians stand out as agents of implementation of this policy, developing multiple actions of user embracement. The nurse is evidenced as an educator in health, leader in the family health team, and capable of creating emotional bond with users. Conclusion It was found that the innovations proposed in the treatment are incipient in the daily work of nurses.

Compétences en santé déficientes: obstacle à une prise en charge optimale [Low health literacy: barrier to optimal care].

Health literacy is defined as "the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions." Low health literacy mainly affects certain populations at risk limiting access to care, interaction with caregivers and self-management. If there are screening tests, their routine use is not advisable and recommended interventions in practice consist rather to reduce barriers to patient-caregiver communication. It is thus important to include not only population's health literacy but also communication skills of a health system wich tend to become more complex.

Prise en charge des ruptures de la coiffe des rotateurs

Les lésions de la coiffe des rotateurs (CR) constituent une cause fréquente de douleurs de l'épaule. L'origine reste souvent multifactorielle et dépend de facteurs liés aux patients (dégénérescence tendineuse, ostéophyte acromial, cal vicieux, etc.) et de facteurs extérieurs (traumatisme, surcharge) consécutifs ou non aux activités professionnelle et sportive. L'efficacité de la prise en charge, qu'elle soit conservatrice ou chirurgicale, dépend autant du traitement de la lésion de la CR que de sa cause. Il apparaît donc Indispensable, avant de traiter une lésion de la CR, de poser au préalable un diagnostic lésionnel et étiopathogénique précis. Cette revue, qui s'adresse en premier lieu aux praticiens en médecine générale, a pour but de rappeler les modalités de prise en charge des lésions de la coiffe des rotateurs.

Simultaneous determination of antidementia drugs in human plasma: Procedure transfer from HPLC-MS to UPLC-MS/MS.

A previously developed high performance liquid chromatography mass spectrometry (HPLC-MS) procedure for the simultaneous determination of antidementia drugs, including donepezil, galantamine, memantine, rivastigmine and its metabolite NAP 226-90, was transferred to an ultra performance liquid chromatography system coupled to a tandem mass spectrometer (UPLC-MS/MS). The drugs and their internal standards ([(2)H(7)]-donepezil, [(13)C,(2)H(3)]-galantamine, [(13)C(2),(2)H(6)]-memantine, [(2)H(6)]-rivastigmine) were extracted from 250μL human plasma by protein precipitation with acetonitrile. Chromatographic separation was achieved on a reverse phase column (BEH C18 2.1mm×50mm; 1.7μm) with a gradient elution of an ammonium acetate buffer at pH 9.3 and acetonitrile at a flow rate of 0.4mL/min and an overall run time of 4.5min. The analytes were detected on a tandem quadrupole mass spectrometer operated in positive electrospray ionization mode, and quantification was performed using multiple reaction monitoring. The method was validated according to the recommendations of international guidelines over a calibration range of 1-300ng/mL for donepezil, galantamine and memantine, and 0.2-50ng/mL for rivastimgine and NAP 226-90. The trueness (86-108%), repeatability (0.8-8.3%), intermediate precision (2.3-10.9%) and selectivity of the method were found to be satisfactory. Matrix effects variability was inferior to 15% for the analytes and inferior to 5% after correction by internal standards. A method comparison was performed with patients' samples showing similar results between the HPLC-MS and UPLC-MS/MS procedures. Thus, this validated UPLC-MS/MS method allows to reduce the required amount of plasma, to use a simplified sample preparation, and to obtain a higher sensitivity and specificity with a much shortened run-time.
