Concept
Occupational lung disease
Résumé
Occupational lung diseases are work-related, lung conditions that have been caused or made worse by the materials a person is exposed to within the workplace. It includes a broad group of diseases, including occupational asthma, industrial bronchitis, chronic obstructive pulmonary disease (COPD), bronchiolitis obliterans, inhalation injury, interstitial lung diseases (such as pneumoconiosis, hypersensitivity pneumonitis, lung fibrosis), infections, lung cancer and mesothelioma. These diseases can be caused directly or due to immunological response to an exposure to a variety of dusts, chemicals, proteins or organisms.
Occupational cases of interstitial lung disease may be misdiagnosed as COPD, idiopathic pulmonary fibrosis, or a myriad of other diseases; leading to a delay in identification of the causative agent.
Occupational asthma
Asthma is a respiratory disease that can begin or worsen due to exposure at work and is characterized by episodic narrowing of the respiratory tract. Occupational asthma has a variety of causes, including sensitization to a specific substance, causing an allergic response; or a reaction to an irritant that is inhaled in the workplace. Exposure to various substances can also worsen pre-existing asthma. People who work in isocyanate manufacturing, who use latex gloves, or who work in an indoor office environment are at higher risk for occupational asthma than the average US worker. Approximately 2 million people in the US have occupational asthma.
Bronchiolitis obliterans
Bronchiolitis obliterans, also known as constrictive bronchiolitis or obliterative bronchiolitis is a respiratory disease caused by injury to the smallest airways, called bronchioles. It has been reported to occur from exposure to inhaled toxins and gases including sulfur mustard gas, nitrogen oxides, diacetyl (used in many food and beverage flavorings), 2,3-pentanedione, fly ash and fiberglass.
Chronic obstructive pulmonary disease
Chronic obstructive pulmonary disease is a respiratory disease that can encompass chronic bronchitis and/or emphysema.
