1 Coal Worker’s Pneumoconiosis
Penyaji : Dr. Sinatra Gunawan, MK3, SpOk Referensi : Amer Rassam MD1, Gerry San Pedro MD2, Daniel Banks MD1. Department of Internal Medicine LSUHSC-Shreveport

2 Coal Worker’s Pneumoconiosis
Simple CWP Asymptomatic Black dust macules in respiratory bronchioles CXR – Bilateral, small parenchymal nodules Simple silicosis and simple CWP look identical on CXR

3 Coal Worker’s Pneumoconiosis
Progressive CWP Large fibrotic lung masses called progressive massive fibrosis (PMF) PMF of nodules > 2 cm Melanoptysis No hilar involvement No association with TB No specific treatment

4 Berylliosis

5 Berylliosis Causative agent: Beryllium Cell-mediated immune response
Working in high-tech electronics, alloys, ceramics, and pre-1950 fluorescent light manufacturing 2 year exposure to even slight amount can cause disease Chronic interstitial pneumonitis (upper lobes) Hilar lymphadenopathy identical to Sarcoidosis

6 Berylliosis Acute Exposure Massive accidental exposure
CXR – Pulmonary edema Treat immediately with prednisone Recovery within 1-6 months Risk of death is 5-10%

7 Berylliosis Chronic Exposure Granulomatous disorder
Skin lesions, granulomatous hepatitis, hypercalcemia Beryllium lymphocyte proliferation test (this is how to separate from Sarcoidosis) Treat with prednisone Beryllium clearance from the lungs is slow

8 Berylliosis Again … Remember !
Beryllium lymphocyte proliferation test is the single best test to identify beryllium sensitization and beryllium chronic disease Beryllium is the only pneumoconiosis that can be treated (corticosteroids)

9 Hard-Metal Lung Disease

10 Hard-Metal Lung Disease
Exposure to tungsten carbide and cobalt Used as an abrasive or metal cutting tool Cause air flow obstruction or diffuse interstitial fibrosis. Asthma-like syndrome towards the end of the work shift or in the evening. Develop rapidly within a year of employment P/E – Basilar rales. CXR – irregular opacities with hilar prominence
