[Registry of occupational respiratory diseases in Navarre]

In January 2002 an occupational respiratory diseases record was established in Navarre so that the number and characteristics of the occupational respiratory pathology could be analysed.

The cases reported by doctors who collaborated in 2002, 2003 and 2004, were entered in a database for subsequently analysis. This database has several variables: gender, age, tobacco habit, hospital department and notifying doctor, diagnosis, job and causal agent.

125 cases were reported. 97 males (77.6%) and 28 females (22.4%). Average age was 55,4 years old. Eighty-eight were non-smokers (70.4%) and 37 were smokers (29.6%). Pneumology reported 84 cases (67.2%) and Allergology 41 (32.8%). The diagnoses were: 50 bronchial asthma (40%), 31 benign pleural disease (24.8%), 8 extrinsic allergic alveolitis (6.4%), 8 mesothelioma (6.4%), 7 bronchopulmonary cancer (5.6%), 5 acute inhalations (4%), 3 amianthinopsy (2.4%), 2 rhinitis (1.6%), 1 RADS (0.8%) and 1 COPD (0.8%). The most reported jobs were: 13 painting and varnishing (10.4%), 12 spinning asbestos yarn (9.6%) and 8 bakery and confectionery (6.4%). The main causal agents were: 49 cases of asbestos (39.2%), 15 isocyanates (12%) and 8 silica (6.4%).

The most frequent pathology was bronchial asthma, followed by benign pleural disease. The most reported job was painting and varnishing and secondly spinning asbestos yarn. Asbestos was the first substance involved and the second was isocyanates. Most of the patients were males and non-smokers. The Pneumology Service of the Virgen del Camino Hospital reported most of the cases. Ratio contrast analysis showed a certain tendency towards a statistical significance in rhinitis, occupational asthma and amianthinopsy.
