Pneumoconiosis is an occupational lung disease and a restrictive lung disease caused by the inhalation of dust, often in mines.
Types
Depending upon the type of dust, the disease is given different names:
- Coalworker's pneumoconiosis (also known as "miner's lung", "black lung" or anthracosis) - coal, carbon
- Asbestosis - asbestos
- Silicosis (also known as "grinder's disease" or Potter's rot) - silica
- Bauxite fibrosis - bauxite
- Berylliosis - beryllium
- Siderosis - iron
- Byssinosis - cotton
- Silicosiderosis - mixed dust containing silica and iron
- Labrador Lung (found in miners in Labrador, Canada) - mixed dust containing iron, silica and anthophyllite, a type of asbestos
Diagnosis
Positive indications on patient assessment:
- Shortness of breath
- Chest X-ray may show a characteristic patchy, subpleural, bibasilar interstitial infiltrates or small cystic radiolucencies called honeycombing
Pneumoconiosis in combination with multiple pulmonary rheumatoid nodules in rheumatoid arthritis patients is known as Caplan's syndrome.[1]
- Popcorn workers lung disease - Diacetyl emissions and airborne dust from butter flavorings used in microwave popcorn production
Popular culture references
- In the classic British film Brief Encounter (1945), derived from a Noël Coward play, housewife Laura (Celia Johnson) and physician Alec (Trevor Howard) begin an affair. She is desperately mesmerized in a train station lounge by his evocation of his passion for pneumoconioses:
- Laura: “You were saying about the coal mines…”
- Alec: “Oh yes, the inhalation of coal dust…That’s one specific form of the disease. It’s called anthracosis.”
- Laura [Tenderly]: “What are the others?”
- Alec: “Chalicosis. That comes from metal dust. Steel works, you know…”
- Laura [Breathlessly]: “Yes, of course… Steel works…”
- Alec: “And silicosis… That’s stone dust… Gold mines…”
- Laura [Almost swooning]: “I see…”
- Bell rings
- Laura: “There’s your train.”
- Alec: “Yes.”
- Laura: “You mustn’t miss it.”
- Alec: “No.”
- In the 1995 British film Brassed Off, the band leader (Pete Postlethwaite) in a small coal-mining town is hospitalized with pneumoconiosis.
- 2006 documentary film by Shane Roberts. Features interviews with miners suffering from the disease and footage shot inside the mine
- 1000 Ways to Die featured an incident where two kitchen workers succumb to Pneumoconiosis from playing in cocoa powder.
- In the widely acclaimed Puzzle/Shooter game Portal 2, former CEO and founder of Aperture Science Laboratories, Cave Johnson, purportedly contracted and died of Lunar Pneumoconiosis after prolonged exposure to the moon rocks he was utilizing in teleportation technology research.
