pneumoconiosis

 [noo″mo-ko″ne-o´sis]
any of a group of lung diseases resulting from inhalation of particles of industrial substances, particularly inorganic dusts such as the dust of iron ore or coal, and permanent deposition of substantial amounts of such particles in the lungs. The diseases vary in severity but all are occupational diseases, acquired by workers in the course of their jobs. Symptoms include shortness of breath, chronic cough, and expectoration of mucus containing the offending particles.

Silicosis is probably the best known and most severe of these diseases. asbestosis, caused by inhalation of asbestos fibers, is probably second only to silicosis in severity. Prevention and early diagnosis are important, for no effective treatment is available. Coal workers' pneumoconiosis, or black lung, usually in the form of bituminosis or anthracosilicosis, is caused by the inhalation of coal dust, often with silica, and is similar in its development and its effects to silicosis. Berylliosis is a variety found in workers exposed to beryllium in the manufacture of fluorescent lamps, and in members of their families who are contaminated by the chemicals in the worker's clothing. Other types of pneumoconiosis include aluminosis, cadmiosis, and siderosis.
talc pneumoconiosis a type of silicatosis caused by the inhalation of talc; symptoms include shortness of breath, cough, fatigue, weakness, and weight loss. Prolonged exposure may result in pulmonary fibrosis. Called also talcosis.

(nū'mō-kō'nē-ō'sis, nū'mō-kō'nē-ō'sis, -sēz),
Inflammation commonly leading to fibrosis of the lungs caused by the inhalation of dust incident to various occupations; characterized by pain in the chest, cough with little or no expectoration, dyspnea, reduced thoracic excursion, sometimes cyanosis, and fatigue after slight exertion; often leads to chronic restrictive lung disease as measured by pulmonary testing; degree of disability depends on the types of particles inhaled, as well as the level of exposure to them.

pneumoconiosis

Any of a group of conditions in which a mineral dust, such as asbestos, bauxite, coal dust, diatomite, granite dust, quartz, silicon or talc, has accumulated in the lungs. The significance depends on the material and the particle size. Pneumoconiosis may cause severe lung damage with scarring (FIBROSIS) that may interfere with lung function. It may also lead to secondary HEART FAILURE and an increased risk of TUBERCULOSIS and lung cancer. See ANTHRACOSIS, ASBESTOSIS, SILICOSIS, SIDEROSIS.

Pneumoconiosis (plural, pneumoconioses)

Any chronic lung disease caused by inhaling particles of silica or similar substances that lead to loss of lung function.
