- symptoms(sx) just like other asthma
- caused by irritants & chemicals
- Industrial Bronchitis
- Identical symptoms to chronic
bronchitis seen with cigarette smoking
- Coal workers & Grain workers
- Identical symptoms to chronic
bronchitis seen with cigarette smoking
- Allergic alveolitis
- alveolar and bronchiolar level
- Hypersensitivity reaction
- Causes
- Farmer’s Lung
- hay
- hay
- Pigeon breeder’s lung
- feces
- feces
- Bagassosis
- bagasse- substance produced when juice is extracted
from sugarcane & is used in making paper & explosives
- bagasse- substance produced when juice is extracted

- Byssinosis
- cotton dust
- cotton dust
- Farmer’s Lung
- Sign & Symptoms
- coughing, fever, tightness in chest,
extreme tiredness & aching
- chronic stage- trouble breathing
- coughing, fever, tightness in chest,
extreme tiredness & aching
- Diagnosis
- Chest Xray
- Pft test should be done to confirm the diagnosis
- Chest Xray
- Treatment
- Wearing of mask(PPE)
- steroid- immunosuppresive
- reduce inflammation
- reduce inflammation
- Wearing of mask(PPE)
- alveolar and bronchiolar level
- RADS: The Reactive Airways Dysfunction Syndrome
- Pneumoconiosis
- accumulation of dust in the lungs and the tissue reactions to its presence
- tissue reaction may be non-collagenous( minimal stromal reaction) or
collagenous(when scarring is permanent)
- Characterised by fibrosis & caused by chronic inhalation of mineral dusts
- lungs cannot expand- dyspnea
- lungs cannot expand- dyspnea
- Sign & Symptoms
- dyspnea, Shortness of breath, Chest pain
- dyspnea, Shortness of breath, Chest pain
- accumulation of dust in the lungs and the tissue reactions to its presence
- Asbestosis
- Diffuse fibrosis caused by a persistent alveolar inflamation
- Irregular opacities predominantly in the lung bases
- Clubbing is common
- Diffuse fibrosis caused by a persistent alveolar inflamation
- Silicosis
- Simple Silicosis
- small nodules, predominantly in upper lobes;
patient often symptomatic
- small nodules, predominantly in upper lobes;
patient often symptomatic
- Complicated Silicosis
(Progressive Massive
Fibrosis)
- coalescence into large nodules or masses with retraction of
upper lobes
- coalescence into large nodules or masses with retraction of
upper lobes
- Simple Silicosis
- Coal Worker’s Pneumoconiosis (CWP)
- Can cause industrial bronchitis, emphysema and progressive massive fibrosis
- Xray looks worse than patient
- Simple CWP
- asymptomatic
- small rounded opacities predominantly in the upper lobes
- asymptomatic
- Complications
- Caplan’s Syndrome
- syndrome with rheumatoid arthritis features, PMF, and
usually (>70%) a positive rheumatoid factor
