Pneumoconiosis (CWP)
All of the following restrictive conditions fall under the diagnosis of pneumoconiosis: Black lung disease is predominant in coal miners who inhale coal dust. Farmer's lung is caused by inhaling farm-related dust. These lung diseases are caused by lung inflammation and scarring, known as pulmonary fibrosis, which cause a decreased ability to hold air in the lungs. Common symptoms of restrictive lung diseases include coughing, shortness of breath, wheezing and chest pain. Coal worker's pneumoconiosis. Coal worker's pneumoconiosis is caused by inhaling coal dust. Also known as black lung disease, the condition, in severe cases, is characterized by scarring on the lungs (which often permanently damages the lungs and may lead to shortness of breath). About 2.8 percent of coal miners have coal worker's pneumoconiosis. Silicosis. Examples of organic dust diseases. Byssinosis. Byssinosis is caused by dust from hemp, flax, and cotton processing. Also known as brown lung disease, the condition is chronic and characterized by chest tightness and shortness of breath. Chronic obstructive pulmonary disease (COPD), also known as chronic obstructive lung disease (COLD), and chronic obstructive airway disease (COAD), among others, is a type of obstructive lung disease characterized by chronically poor airflow. It typically worsens over time.  Black lung disease: A disease of the lungs that is caused by inhaling coal dust, which in some patients can lead to progressive massive fibrosis of the lungs and severely impaired lung function. Also known as anthracosis and coal miner's pneumoconiosis.  Black lung disease is a common name for any lung disease that develops from inhaling coal dust. This name comes from the fact that those with the disease have lungs that look black instead of pink. Medically, it is a type of pneumoconiosis called coal workers' pneumoconiosis (CWP). There are two forms: simple CWP and complicated CWP, which also involves progressive massive fibrosis (PMF) Black lung disease was first reported back in 1822. Doctors were under the impression that the the symptoms from black lung disease were asthma related. and called it miners a … sthma. However when In 1831, Upon discovering the blackening of miners lungs the term black lung disease was created.  The only way to prevent black lung disease is to avoid long-term exposure to coal dust. Coal mines may help prevent the condition by lowering coal dust levels and providing protective clothes to coal miners. A light micrograph of a human lung containing particles of inspired coal dust (anthracosis). Some patients develop emphysema (a disease in which the tiny air sacs in the lungs become damaged, leading to shortness of breath, and respiratory and heart failure) as a complication of black lung disease. Coal workers' pneumoconiosis (CWP), also known as black lung disease or black lung, is caused by long exposure to coal dust. It is common in coal miners and others who work with coal.  Definition. Black lung disease is the common name for coal workers' pneumoconiosis (CWP) or anthracosis, a lung disease of older workers in the coal industry, caused by inhalation, over many years, of small amounts of coal dust. Some patients develop emphysema (a disease in which the tiny air sacs in the lungs become damaged, leading to shortness of breath, and respiratory and heart failure) as a complication of black lung disease. Types of pneumoconiosis. The disease appears in different forms, depending on the type of dust you inhale. One of the most common forms is black lung disease, also known as miner's lung. It’s caused by breathing in coal dust. Another is brown lung, which comes from working around dust from cotton or other fibers.
