Statistics

Se han estudiado 106 trabajadores de entre 1.000 de una factoría de fibras sintéticas provistas de instalaciones de aire acondicionado con humidificadores. Treinta y seis de ellos evidenciaron clínica compatible con alveolitis alérgica extrínseca (3,6% sobre el total de operarios). Diecinueve presentaron clínica aguda (52,7%), y 17 clínica subaguda (47,3%). Se objetivó el valor diagnóstico de la historia clínica y de la prueba de provocación en el lugar de trabajo. Las intradermorreacciones, las precipitinas en sangre y la radiología de tórax fueron escasamente rentables. El estudio de los barros y del agua de los humidificadores demostró la presencia de diversos microorganismos con escasos actinomicetos termofílicos.

Tres años después de la limpieza de los humidificadores, objetivamos un nuevo caso de alveolitis.

The authors studied 106 workers of 1,000 in a synthetic fiber mill equiped with an airconditioning Systems with humidifiers. Clinical signs compatible with extrinsic allergic alveolitis were found in (3.6%/l,000 workers) of these, 19 (52.7%) had acute clinical signs and 17 (47.3%) subacute symptoms. The clinical history and challenge test in the work place were found useful diagnostic aids. The intradermal reactions, blood precipitin tests and chest films were not efficacious. Study of the bars and water of the humidifiers revealed the presence of various microorganisms with scant thermophylic actinomycetes.Three years after humidifiers were cleaned a new case of alveolitis was diagnosed.
