Valoración médico-legal del dolor lumbar en una población trabajadora

Martín Utrillas, Carmen 26 September 2002 (has links)
PLANTEAMIENTO DEL ESTUDIO: Desde el punto de vista de la VALORACIÓN MÉDICO-LEGAL, la lumbalgia de origen laboral, genera un problema de Incapacidad Temporal (IT) o Permanente, y es la causa más importante de desembolso económico para nuestro sistema de Seguridad Social. Existe una gran dificultad en la Valoración del Daño Corporal (VDC) para medir e indemnizar los casos de lumbalgia.MATERIAL Y MÉTODOS: Estudio de la población laboral activa de la provincia de Valencia. Se determinó una muestra que quedó reducida a 1.346 sujetos: 958 varones (71'17%) y 388 mujeres (28'83%).A través de una encuesta adaptada se estudiaron los factores:Demográficos. Laborales. Condiciones del puesto de trabajo. Datos sobre lumbalgia. Entorno laboral. Trabajo con pantallas de visualización de datos (PVD).A partir de este estudio de la población se determinan las consecuencias médico-legales para la valoración del dolor lumbar.RESULTADOS Y CONCLUSIONES:En nuestro estudio se han recogido 343 bajas por lumbalgia (el 56,51%).Debemos destacar que los factores considerados de mayor riesgo en las actividades laborales son varios. Por orden de importancia: los esfuerzos (36,74 %), las posturas forzadas (32,45 %) y los falsos movimientos (21,58 %), que se podrían también corresponder con posturas forzadas.Resulta muy difícil establecer un perfil de riesgo de patología lumbar, debido a la multiplicidad de los factores causales implicados.En nuestro estudio, 229 trabajadores (17,01%) eran usuarios de pantallas de visualización de datos. Con características específicas, independientes de la actividad y ocupación.Entre ellos los factores de riesgo más significativos, vienen constituidos por el apoyo y la posición de la espalda respecto a la silla, la altura de la mesa, así como la situación y posición de los documentos con los que se trabaja.Por lo que se refiere a los factores psicosociales, la tensión nerviosa se ha revelado como el que guarda una relación muy significativa con las lumbalgias (Odds ratio 2,81 y p < 0,0002).De nuestro estudio se desprende la magnitud del problema del dolor lumbar y su importante repercusión socio-económica, coincidiendo con estudios previos.En nuestra Comunidad Autónoma Valenciana, se dan en mayor medida que en el resto del Estado, la incidencia del dolor lumbar y de incapacidad temporal por este motivo.Es necesario mejorar las medidas técnicas, organizativas y de formación e información, pues las estrategias de prevención de los trastornos lumbares relacionados con la actividad laboral, se basan en intervenciones en el lugar de trabajo y en la atención médica.Aunque se dispone de algunos instrumentos para la evaluación clínica del impacto del dolor lumbar en la aptitud para el trabajo, es imperativo buscar fórmulas que permitan en estos casos una valoración del daño corporal objetiva, fiable y reproducible.Para lograrlo debe seguirse investigando, y así establecer protocolos de consenso entre los profesionales dedicados a la valoración del daño corporal, aplicables a este tipo de patología, de tal modo que se minimicen las discrepancias de resultados que existen entre unas valoraciones y otras.Considero que debería estudiarse la posibilidad de crear unas unidades de apoyo, integradas por profesionales de los distintos campos implicados para la ayuda en la toma de decisiones, tanto desde el punto de vista clínico como médico-legal, en los casos que lo requiera por su especial dificultad o problemática. / STUDY'S ENOUNCEMENT:From the MEDICAL-LEGAL evaluation's point of view, the origin of laborer lumbar pain, the more important cause becomes of economic expenditure for our social security system. MATERIAL And METHODS: Study of the worker population active of the from Valencia department. It was determined a sign that she got reduced to 1,346 subjects: 958 males and 388 females.OUTCOMES and CONCLUSIONS:It have picked 343 casualties for lumbar pain up In our study ( the 56.51).We must stand out than the considerate bigger risk factors in the work activities: The efforts and the postures enforced (36.74).In our study, 229 workpeople were visual display screens users of visualization of data (17.01). Among themselves the more- risk factors significant, they are composed of the support and the documents's position of the back in relation to the chair, the height of table, as well as the situation and position that it is worked up with. As regards the factors psycho-social, stress has been revealed as the that he puts away a very significant relation with them lumbar pain.In our Valencian Autonomous region, they come to happen that in principal once was measured in the state rest, the incidence of the lumbar and temporary incapacity's pain for this motive.It is necessary to improve measured techniques, organizational and of formation and information, because the strategies spare of the lumbar upsets related with the worker activity, they are based on interventions on the job and in the medical attention.I must be followed investigating and establishing consent protocols among the dedicated professionals to the corporal damage's evaluation, in such a manner that the outcomes discrepancies that exist among an evaluations and another one reach a minimum .I should be studied the possibility to create a units supportive, integrated for professionals of the distinct implicated fields for the decision makings, point from the clinical point of view as medical-legal, in the cases than require it for his special difficulty or problems.

Risk factors for allergic disease in the first two years of life

Fleming, Sheelagh January 2003 (has links)
A cohort of 2000 women was recruited in early pregnancy when blood was taken, a full family history of allergic disease was obtained and skin prick tests were performed. Data about diet during pregnancy were collected from a food frequency questionnaire.  Information on symptoms of allergic disease, smoking and home environment, illness history, antibiotic usage and infant diet were all requested by postal questionnaire at 6, 12 and 24 months of age.  A sample of 151 children had skin prick tests performed to determine allergic status at two years of age;  10% were positive.  As expected male gender and maternal atopy were associated with wheeze in the first two years of life, while maternal atopy was the only consistent association between the administration of antibiotics and early wheeze.  Some non-significant trends were found suggesting an inverse association between maternal dietary vitamin C showed trends towards a positive association as did total fruit intake.  Maternal plasma vitamin C also showed a positive association with wheeze in the second year of the child’s life.  No association were found between selenium or n-6:n-3 fatty acid ratio and wheeze or eczema in the first two years of life.  Antibiotics given for non-chest/cold or non-skin conditions in the first six months of life were associated with wheeze and eczema in the second six months and second year of life.
