Asbestosis is long-term inflammation and scarring of the lungs due to asbestos fibers. [4] Symptoms may include shortness of breath , cough, wheezing , and chest tightness . [ 1 ] Complications may include lung cancer , mesothelioma , and pulmonary heart disease .
The first known U.S. workers' compensation claim for asbestos disease was in 1927. In 1930, the first reported autopsy of a person with asbestosis was conducted in the United States and later presented by a doctor at the Mayo Clinic, although in this case the exposure involved mining activities somewhere in South America.

Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...
It may cause other lung cancers and respiratory diseases such as asbestosis. [7] When asbestos fibers can easily be made into airborne dust, the material is known as "friable". For example, a popcorn ceiling is extremely friable, whereas asbestos floor tile is considered non-friable.
[1] [2] The three most common types are asbestosis, silicosis, and coal miner's lung. [3] Pneumoconiosis often causes restrictive impairment, [4] although diagnosable pneumoconiosis can occur without measurable impairment of lung function. [1] [2] Depending on extent and severity, it may cause death within months or years, or it may never ...
The Berlin definition included ALI as a mild form of ARDS. [53] However, the criteria for the diagnosis of ARDS in the Berlin definition excludes many children, and a new definition for children was termed pediatric acute respiratory distress syndrome (PARDS); this is known as the PALICC definition (2015). [54] [55]
Asbestosis - A lung disease first found in textile workers, [11] [12] [13] asbestosis is a scarring of the lung tissue resulting from the production of growth factors that stimulate fibroblasts (the scar-producing lung cells) to proliferate and synthesize the scar tissue in response to injury by the inhaled fibers. The scarring may eventually ...
The standard radiographs provide differing types ("shape and size") and severity ("profusion") of abnormalities seen in persons with pneumoconiosis, including Coal Workers’ Pneumoconiosis, silicosis, and asbestosis. The reader then classifies the subject x-ray, often recording the findings on the NIOSH Roentgenographic Interpretation form.
