16
Q

Chronic Hypersensitivity Pneumonitis

A 
Repeated low dose exposure over time
Progressive breathlessness and cough
Crackles
CXR = Pulmonary Fibrosis
Pulmonary Function = restrictive
17
Q

Treatment of Chronic Hypersensitivity Pneumonitis

A

Remove antigen exposure

Oral steroids if breathless or low gras transfer

18
Q

Idiopathic Pulmonary Fibrosis

A 
Most common interstitial lung disease
Progressive breathlessness, dry cough
Clubbing, bilateral fine inspiratory crackles
CXR = bilateral infiltrates
CT = reticulondular fibrotic shadowing
19
Q

Simple Pneumoconiosis

A

CXR abnormality only

No impairment of lung function

20
Q

Complicated pneumoconiosis

A

Progressive massive fibrosis (restrictive)

21
Q

Caplans syndrome

A

Rheumatoid pneumoconiosis

22
Q

Silicosis

A

15-20 years exposure to Quartz

CXR = egg shell calcification of hilar nodes

23
Q

Asbestos

A

Mining, construction
Pleural disease:
1. Benign pleural plaques - asymptomatic
2. Acute asbestos pleuritis - fever, pain, bloody pleural effusion
3. Pleural Effusion and Diffuse Pleural Thickening - restrictive impairment
4. Malignant mesothelioma - fatal
