Pathology: Lung fibrosissecondary to inflammation caused by inhaled particles
Aetiology: Coal workers pneumoconiosis: coal dustparticles
Silicosis: silica particles, found in many industriesincluding metal mining, quarrying and ceramics manufacturing
Asbestosis: asbestosis fibres, previously used as a commonmaterial for fireproofing and insulation
Symptoms: Maybe asymptomatic, progressive dyspnoea
Signs: Fingerclubbing, end inspiratory crackles.
Investigations: Spirometry: Restrictive defect.
Chest X-Ray: Interstitial changes, pleural plaques withasbestos exposure
Treatment: Avoidcausative particles, otherwise supportive treatment.
Complications: Patientsexposed to asbestos are at a much greater risk of developing bronchial carcinomaand malignant mesothelioma.
Patientswith silicosis are at increased risk of developing tuberculosis
Prognosis: Dependson degree of fibrosis
Patientswith industrial lung disease are often eligible to claim compensation throughthe Industrial Injuries Act
