Farmers Bird Breeders Cheese Workers Mollusc Shell Workers Paprika splitters
Diseases from occupations which may lead to pneumoconiosis
Abestosis
Silicosis
Coal Workers lungs
Berylliosis
Typical CT pattern in chronic hypersensitivity pneumonitis
extensive fibrosis with honeycombing and air-trapping
Focus for treatment of occupational and environmental lung diseases
antigen avoidance
Development of mesothelioma occurs over…
20 years (30 - 40 usually) after exposure
Asbestos and Smoking do not increase the risk of developing lung cancer over the individual components - True or false
False - the risk increases, RR is 30-50 times higher with exposure to both
Indoor environmental sources of lung disease
asbestos; mould; cooking smoke; passive smoking; nanoparticles
Outdoor environmental sources of lung disease
air and traffic pollution
Areas which are most likely to suffer from indoor damp and mould which increases lung disease
deprived and overcrowded
Most dominant part of photochemical Smog
ozone O3
photochemical smog components
ozone; nitrogen oxide; nitrogen dioxide; volatile organic compounds (VOCs)
Most common hazardous air pollutants
Sulphur dioxide Nitrogen oxides Particular matter Ozone and VOCs Persistent Organic Compounds Benzene Carbon monoxide Lead and Heavy metals
Effects of traffic fumes on lung disease (3)
Reduced lung growth in adolescents
Increased rates of asthma and COPD
Increased rates of resp. symptomes i.e. cough, wheeze and breathlessness
Effects of inhaled substances outside the lungs
Low Birth Weight
Appendicitis
Stroke
Neurological disease i.e. Neurodegeneration, cognitive decline, depression, suicide
Dioxins are associated with…
