  • Pneumoconiosis: Symptoms, risk factors, and management

    Oct 08, 2017Different forms of the disease include coal workers' pneumoconiosis (CWP), also known as black lung disease, and byssinosis, also known as brown lung disease, caused by cotton fibers. Pneumoconiosis caused by asbestos is called asbestosis. If a person breathes in harmful dust particles, they can be deposited in the lungs.

  • Severe Occupational Pneumoconiosis Among West ian

    Miners inhale dust at work and are at a risk for coal workers pneumoconiosis (CWP), a preventable and potentially fatal lung disease. After regulations were implemented in the 1970s, declines were reported in both dust levels and the prevalence of simple and advanced CWP until about 2001, when despite stable reported dust levels, disease levels sharply increased.

    Pneumoconiosis is a fibronodular lung disease. The patient is affected when they inhale any but most commonly, silica or coal dust. The same can be said for the inhalation of graphite, tin, chromate, barium, and iron dusts. It is c ommon in miners or people who work in c arbon black and carbon electrode

  • Coal Worker's Pneumoconiosis

    Dec 16, 2015Coal worker's pneumoconiosis (CWP) can be defined as the accumulation of coal dust in the lungs and the tissue's reaction to its presence.The disease is divided into 2 categories: simple coal worker's pneumoconiosis (SCWP) and complicated coal worker's pneumoconiosis (CCWP), or progressive massive fibrosis (PMF),depending on the extent of the

  • Pneumoconiosis Causes

    The inhalation of silica dust is the most prevalent cause of pneumoconiosis and this is prevalent among workers in mining and pottery making – just 0.2 ounces of silica in the lung can bring about silicosis (a form of pneumoconiosis). This type of pneumoconiosis is normally developed over a number of year's exposure to the dust.

  • Coal Worker's Pneumoconiosis Clinical Presentation

    Dec 16, 2015Miners with simple coal worker's pneumoconiosis are usually asymptomatic. They may report cough or sputum production, but this is generally secondary to industrial bronchitis or smoking and not to the body's reaction to coal.Complicated coal worker's pneumoconiosis produces cough, dyspnea, and lung function impairment.

  • Silicosis and coal workers' pneumoconiosis.

    Exposure to coal mine dust and/or crystalline silica results in pneumoconiosis with initiation and progression of pulmonary fibrosis. This review presents characteristics of simple and complicated coal workers' pneumoconiosis (CWP) as well as pathologic indices of acute and chronic silicosis by summarizing results of in vitro, animal, and human investigations.

  • Coal Worker's Pneumoconiosis (Black Lung Disease, Coal

    Coal worker's pneumoconiosis (CWP) is a type of lung disease that is caused by inhaling coal dust particles. It is commonly known as black lung disease or coal miner's lung . As with other common types of pneumoconiosis, namely asbestosis (asbestos fibers) and silicosis (silica particles, coal worker's pneumoconiosis may result in extensive fibrotic scarring of the lung tissue.

  • Coal Workers' Pneumoconiosis

    Coal workers' pneumoconiosis (CWP) is caused by inhalation of coal dust. Deposition of dust produces dust-laden macrophages around bronchioles (coal macules), occasionally causing focal bronchiolar emphysema. CWP usually causes no symptoms but can progress to progressive massive fibrosis (PMF

  • Black lung's back? How we became complacent with coal

    Apr 20, 2016The sinister part is the slow progressing breathing disorder that develops over many years due to excessive lung inflammation and scarring that is triggered by coal mine dust. This disease, coal workers' pneumoconiosis or black lung, is preventable and was widely considered a thing of the past in Australian miners.

  • The Struggle for Coal Miners' Health Care and Pension

    Mar 11, 2019As a result, there are only a few thousand union coal miners left to pay into these funds, while roughly 12 times as many are currently drawing health care and pension benefits. The Great Recession aggravated the situation. Faced with mounting obligation and declining markets, some of the nation's largest coal companies declared bankruptcy. This allowed them to shed their obligations to

  • Advanced Pneumoconiosis Among Working Underground Coal

    *Pneumoconiosis refers to either coal workers' pneumoconiosis (CWP) or silicosis, two similar, chronic fibrotic diseases of the lungs that can result from inhalation of coal-mine dust or silica dust, respectively. Silica dust is more toxic than coal-mine dust, and silicosis historically has developed at a

  • Pneumoconiosis among underground bituminous coal miners in

    Objectives Epidemiological reports since 2000 have documented increased prevalence and rapid progression of pneumoconiosis among underground coal miners in the United States. To investigate a possible role of silica exposure in the increase, we examined chest x-rays (CXRs) for specific abnormalities (r-type small opacities) known to be associated with silicosis lung pathology.

  • Industrial Dust Diseases. About Industrial Dust Diseases

    Oct 20, 2014The term 'pneumoconiosis' refers to a group of lung diseases caused by the inhalation and retention of dust in the lung. This causes a range of granulomatous and fibrotic changes. In modern times, the most commonly occurring variant, apart from asbestosis, is coal worker's pneumoconiosis (CWP), arising from the inhalation of coal dust.
