[Update in respiratory disease and environmental exposure: an invisible relationship]. / Actualización en enfermedad respiratoria y exposición ambiental: una relación invisible.

ABSTRACT

Significant contributions have been made in the past year on different aspects of occupational/environmental respiratory disease. In the case of neoplastic diseases associated with asbestos inhalation, the areas of most interest have been in the search for tumour markers, the importance of the determination of asbestos fibre deposits in biological samples, and new therapeutic schemes in malignant pleural mesothelioma. A consensus article has been published on occupational asthma, in which some clinical evidenced-based recommendations are established, directed at the diagnosis and management of work-related asthma. As regards hypersensitivity-induced pneumonitis, the clinical and evolutionary aspects of this disease have been described in a large series of 86 patients with pigeon-fancier lung. There have also been interesting studies published this year that emphasise the need to take an occupational history in patients with respiratory symptoms in order to look for a causal or synergic relationship with smoking. Finally, the results of studies have been published which were directed at elucidating the role of urban contamination, mainly caused by road traffic, in the deterioration of lung function. A recent study showed that it would be possible to achieve a significant reduction in urban mortality attributed to urban contamination by reducing the levels of PM 2.5. They conclude that more restrictive standards need to be adopted in Europe to protect the health of the population, which coincides with the proposal by the World Health Organisation.
