Introduction: in the field of Occupational Security and Health, highway transportation is still affronting a series of conditionings. The implantation of preventive actions in transport enterprises is been taking place gradually, forced by the interest of government and autonomic administrations, businessmen and workers and their respective organizations. Aim: to evaluate ergonomically the main risks associated to driving. Materials and Methods: the evaluation has three stages: the identification and assessment of the risks professional drivers are at, the assessment of potential pathologies associated to the activity, the identification of bio-chemical indicators involved in the activity. Outcomes: driving long periods without break and highway’s characteristics stood out in the first stage. The second stage is developed beginning from a medical examination and a survey to know the potential pathologies, being the musculoskeletal disorders, diabetes, gastrointestinal and cardiovascular disorders the ones with higher presence. In the first and last stage biochemical indicators are analyzed: cholesterol, glucose, triglycerides and apolipoprotein B. Finally, the causes that may condition them are showed, and also several elements that should be considered to minimize their influence on drivers´ health. Conclusions: the main ergonomic risks were determined as a result of the assessment and it also was reaffirmed the existent criteria of considering that stressing professions compromise several somatic and sensorial structures, the manifestations of which are measurable and allow to infer the burnout the organism suffered.

Introducción: en el campo de la Seguridad y Salud Laboral, el transporte por carretera sigue enfrentándose a una serie de condicionantes. La implantación de actuaciones en materia preventiva en las empresas del sector se viene realizando de una manera gradual, impulsada por el interés de las administraciones estatales y autonómicas, empresarios y trabajadores, y sus organizaciones respectivas. Objetivo: evaluar ergonómicamente los principales riesgos asociados a dicha actividad. Materiales y métodos: la evaluación consta de tres fases: la identificación y evaluación de riesgos a que están sometidos los conductores profesionales, la valoración de patologías potenciales asociadas a la actividad, la identificación de indicadores bioquímicos comprometidos con la actividad. Resultados: se destaca en la primera fase los accidentes de tránsito, los períodos largos de conducción sin descanso y las características de la vía. La segunda fase se desarrolla a partir de un reconocimiento médico y una encuesta para conocer las patologías potenciales, señalándose a los trastornos músculo-esqueléticos, la diabetes, los trastornos gastrointestinales y las alteraciones cardiovasculares como las de mayor presencia. En la tercera y última fase se analizan los indicadores bioquímicos: colesterol, glucosa, triglicéridos y apolipoproteína B. Finalmente se muestran las causas que pudieran condicionarlos, así como algunos elementos que deben ser considerados para minimizar su influencia en la salud de los conductores. Conclusiones: como resultado de la evaluación se determinaron los principales riesgos ergonómicos y se reafirma el criterio existente de considerar que las profesiones estresantes comprometen a diversas estructuras somáticas y sensoriales, cuyas manifestaciones son medibles y permiten inferir el desgaste sufrido por el organismo.

Mais de 500.000 casos novos de malária foram notificados no Brasil, em 1992. P.falciparum and P.vivax são as espécies responsáveis por 99,3% dos casos. O diagnóstico precoce é indispensável para início do tratamento adequado. Neste trabalho, apresentamos os resultados do método tradicional para detecção de plasmódios, gota espessa, e os resultados de métodos alternativos estudados: imunofluorescência indireta com anticorpo policlonal anti-P.falciparum e QBC-método, em grupos populacionais bem definidos. A análise dos resultados foi feita em relação à presença ou ausênsia de sintomas clínicos de malária. Também, diferentes classes de imunoglobulinas anti-P.falciparum foram quantificadas para auxiliar na análise global dos resultados, principalmente nos resultados discrepantes. Nós concluímos que os métodos alternativos são mais sensíveis do que a gota espessa e que a associação das informações epidemiológicas, clínicas e laboratoriais é necessária para definir a presença de malária.

In Brazil, more than 500,000 new cases of malaria were notified in 1992. Plasmodium falciparum and P.vivax are the responsible species for 99.3% of the cases. For adequate treatment, precoce diagnosis is necessary. In this work, we present the results of the traditional Plasmodia detection method, thick blood film (TBF), and the results of alternative methods: Immunofluorescence assay (IFA) with polyclonal antibody and Quantitative Buffy Coat method (QBC)® in a well defined population groups. The analysis were done in relation to the presence or absence of malaria clinical symptoms. Also different classes of immunoglobulins anti-P.falciparum were quantified for the global analysis of the results, mainly in the discrepant results. We concluded that alternative methods are more sensitive than TBF and that the association of epidemiological, clinical and laboratory findings is necessary to define the presence of malaria.
