1

what is coal workers pneumoconiosis

a restrictive, occupational disease which leads to granulomatous and fibrous changes in the lung

The scarring acts like a tumour and progresses the destroying of the lung

2

what causes the granulomatous and fibrotic changes in the lung

dust particles typically 2-5 micrometers in diameter retained in the small airways and alveoli

3

what is the most common form of pneumoconiosis

simple pneumonconiosis

4

what does simple pneumoconiosis refer to?

deposition of coal dust in the lungs

5

symptoms of simple pneumoconiosis

usually COPD related but predominantly they are asymptomatic

There is not much change in respiratory function

6

how is simple pneumoconiosis diagnosed?

CXR abnormality only - it shows micro-nodular function

7

what happens in complicated pneumoconiosis?

round fibrotic masses, several cm in diameter develop in upper lobes

They have necrotic centres

8

what do the upper lobe fibrotic masses lead to ?

apical destruction of the lungs

9

what do people with complicated pneumoconiosis have an increased risk of?

infection

10

what is the pattern with breathlessness in C pneumoconiosis?

restrictive pattern

11

what are the causes of pneumoconiosis?

inhalation and retention of coal dust

12

what are the signs

- finger clubbing
- no cough or dyspnoea

13

what investigations should be done with pneumoconiosis?

- CXR - upper lobe reticular shadowing/fibrosis
- lung function test- not impaired function

14

what is the treatment?

palliative

15

what is caplan's syndrome?

also known as rheumatoid pneumoconiosis, is the combination of seropositive rheumatoid arthritis and a characteristic pattern of fibrosis. Although first described in coal miners (coal workers' pneumoconiosis), it has subsequently been found in patients with a variety of pneumoconiosis.
