coal worker's lungs, chest x-ray, coal workers pneumoconiosis, stage ii, coal workers pneumoconiosis, stage ii #2, coal workers pneumoconiosis, complicated #2, respiratory system, acute silicosis, chronic silicosis, accelerated silicosis, progressive massive fibrosis, conglomerate silicosis, silicosis, respiratory disease, inhalation of silica dust, leads to inflammation, scarring, the lung tissue, three types of silicosis, simple chronic silicosis, results from long-term exposure, than 20 years, to low amounts of silica dust, nodules of chronic inflammation, scarring provoked by the silica dust form, in the lungs, chest lymph nodes, feature breathlessness, resemble chronic obstructive pulmonary disease, copd, accelerated silicosis, occurs after exposure to larger amounts of silica over a shorter period of time, 15 years, inflammation, scarring, symptoms progress faster in accelerated silicosis than in simple silicosis, acute silicosis, results from short-term exposure to very large amounts of silica, lungs, become very inflamed, fill, fluid, causing severe shortness of breath, low blood oxygen levels, progressive massive fibrosis, occur in simple, accelerated silicosis, more common, in the accelerated form, progressive massive fibrosis results from severe scarring, leads to obliteration of normal lung structures, silica, common, naturally-occurring crystal, found in most rock beds, forms dust, mining, quarrying, tunneling, work, many metal ores, silica is a main component of sand, glass workers, sand-blasters also receive heavy exposure to silica, risk factors include any work that includes exposure to silica dust, mining, stone cutting, quarrying, road, building construction, work, abrasives manufacturing, sand blasting, many other occupations, hobbies involve exposure to silica, intense exposure to silica, year, takes at least 10, 15 years of exposure, symptoms develop, silicosis has, become less common, the occupational safety, health administration, osha, instituted regulations requiring the use of protective equipment which limit the amount, silica dust inhaled, chronic cough, shortness of breath, exercise, in patients, progressive massive fibrosis, additional symptoms that associated, in acute silicosis, fever, cough, weight loss, severe breathing difficulty, careful medical history that includes many questions, occupations, hobbies, have exposed to, excessive silica, a physical exam, diagnostic tests to confirm the diagnosis, exclude other diseases, appear similar, chest x-ray, pulmonary function tests, purified protein derivative, ppd, skin test, tuberculosis, no specific treatment, silicosis, removal, the source of silica exposure is important, prevent further worsening, supportive treatment includes cough suppression medications, bronchodilators, oxygen, antibiotics, respiratory infections, considerations, treatment include limiting continued exposure to irritants, smoking cessation, routine tuberculosis skin testing, silicosis, at high risk, developing tuberculosis, tb, silica is believed to interfere, the body's immune response, bacteria that causes, tb, yearly skin testing to check, exposure to tb, anti-tb drugs, a positive skin test, change, in the appearance, the chest x-ray, indicate tb, support groups, others who suffer from silicosis, related diseases, help understand disease, adapt to its treatments, changes in life that result from it, depends upon the extent of damage, lungs, increased risk, tuberculosis, progressive massive fibrosis, have an occupational exposure to silica, symptoms develop, work, high-risk occupation, high-risk hobby, wear dust masks, not smoke, protection, prescribed by osha, respirator, murray j, nadel j, textbook of respiratory medicine, 3rd ed, philadelphia, pa, wb saunders, 2000. , pipavath s, imaging of interstitial lung disease, radiol clin north am, 43(3), 589-599, noble j, textbook of primary care medicine, 3rd ed, mosby, 694-696.
