Pneum

Pneumoconiosis is a group of conditions relating to inhalation of particles.

Causes a Fibrosis of the Lung Tissue.

Are often seen by workers of coal mines, or inhalation of asbestos or silica.

Some individual have a worse reaction

Can be inflammation, fibrosis, and destruction

Symptoms

  • Difficulty breathing  [Dyspnea]
  • Cough
  • Coughing blood  [hemoptyosis]
  • Shortness of breath
  • Pain
  • Black lungs
  • Lung nodules on X-ray
  • Increase risk for Chronic Bronchitis

Coal Worker’s Pneumoconiosis

  • When coal is brought into lungs it causes cells called macrophages to ingest the particles
  • This leads to coal spots or macules
  • Can be seen on X-ray  [typically in the upper lung]
  • The average individual will have no problems or symptoms

Silicosis

  • Exposure to silicon dioxide  [silica]
  • Causes nodules in lungs and calcification of lymph nodes
  • X-ray findings are unusual
  • Typically no symptoms are seen

Asbestosis

  • Causes fibrosis of lung tissue
  • Typically symptoms emerge 15 years post exposure
  • Increase risk for Mesothelioma

Other Pneumoconiosis

  • Siderosis Iron Oxide
  • Stannosis Tin Oxide
  • Baritosis Barium Salts
  • Talcosis Magnesium Silcate
