Pathology
Lung fibrosis secondary to inflammation caused by inhaled particles
Aetiology
Coal workers pneumoconiosis: coal dust particles
Silicosis: silica particles, found in many industries including metal mining, quarrying and ceramics manufacturing
Asbestosis: asbestosis fibres, previously used as a common material for fireproofing and insulation.Signs
Finger clubbing, end inspiratory crackles.
Symptoms
May be asymptomatic, progressive dyspnoea
Investigations
Spirometry: Restrictive defect.
Chest X-Ray: Interstitial changes, pleural plaques with asbestos exposure
Treatment
Avoid causative particles, otherwise supportive treatment.
Prognosis
Depends on degree of fibrosis
Patients with industrial lung disease are often eligible to claim compensation through the Industrial Injuries Act
Patients exposed to asbestos are at a much greater risk of developing bronchial carcinoma and malignant mesothelioma.
Patients with silicosis are at increased risk of developing tuberculosis
