Chalicosis is a form of pneumoconiosis affecting the lungs or bronchioles, found mainly among stonecutters.[1] The disease is caused by the inhalation of fine particles of stone.[2] The term is from Greek, χάλιξ, gravel.
Risk factors
Occupations with significant exposure to stone dust are at an increased risk of chalicosis include:
- Miners[3][1]
- Stone cutters and stone masons[3][4]
- Quarry workers[3][4]
- Pottery and porcelain casters[3][1]
- Tunneller/tunnel workers[3]
- Foundry workers[3]
- Plasterers[4]
Signs and symptoms
Signs and symptoms of chalicosis are slow to develop and thus patients may not show signs of incapacity until years after exposure.[4] It may even take up to 10 years before manifestations of the disorder are present.[3] Signs and symptoms include:
- Dyspnea (uncomfortable breathing sensation/shortness of breath) aggravated by exertion[3][4]
- Chronic, non-productive cough[3]
- Expelled matter, such as phlegm, from the throat or lungs stained gray, black, or red[4]
- Wheezing[3]
- Loss of appetite[1]
- Fatigue[1]
- Emaciation[1]
- Soreness in stomach region[1]
- General malaise[1]
Treatment and Prevention
There is no definitive cure for chalicosis,[5] nor is there a specific targeted therapy.[3] Current treatment of this lung disorder primarily involves managing respiratory symptoms, associated comorbidities, and complications, with the overarching goal of enhancing the patient's quality of life.[5][3] These include:
Acute pharmacotherapies
- Corticosteroids are a class of steroid hormones that can be used for acute management of chalicotic symptoms.[3][5]They are not recommended for chronic management.[3]
Chronic pharmacotherapies
- Whole lung lavage uses saline solution to wash out lodged particles in the lungs.[5]
- Bronchodilators dilate the bronchi and bronchioles to increase airflow to the lungs.[5][3]
- Oxygen therapy or supplemental oxygen is a medical treatment that provides extra oxygen, often to prevent complications of chronic hypoxemia.[3][5]
- Pulmonary rehabilitation is a therapeutic concept which utilizes a series of services to aid improved breathing.[5]
- Antifibrotics.[3]
- Smoking cessation.[3]
- Lung transplantation is a last resort in which one lung, both, or damaged lung tissue are replaced with a donor during a surgical procedure.[5]
