Asbestosis; the HRCT scan shows the typical The pneumoconioses are parenchymal lung diseases that arise from picture of subpleural fibrosis (solid arrow); in addition inhalation of (usually) inorganic dusts at work. Some such dusts are there is diffuse, left-sided pleural thickening (broken biologically inert but visible on a chest X-ray or CT scan; thus, while arrow), characteristic too of heavy asbestos exposure they are radiologically alarming they do not give rise to either clinical disease or deficits in pulmonary function. Others – notably asbestos and crystalline silica – are fibrogenic so that the damage they cause is through the fibrosis induced by the inhaled dust rather than the dust itself. Classically these give rise to characteristic radiological patterns and restrictive deficits in lung function with reductions in diffusion capacity; importantly, they may progress long after exposure to the causative mineral has finished. In the UK and similar countries asbestosis is the commonest form of pneumoconiosis but in less developed parts of the world asbestosis is less frequent than silicosis; these two types are discussed in detail below. Other, rarer types of pneumoconiosis include stannosis (from tin fume), siderosis (iron), berylliosis (beryllium), hard metal disease (cobalt) and coal worker’s pneumoconiosis.

Five had computed tomography of the thorax. All the scans showed marked circumferential pleural thickening often with calcification, and four showed no significant evidence of intrapulmonary fibrosis (asbestosis). Lung function testing showed reduc- tion of the inspiratory capacity and the single-breath carbon monoxide transfer factor (TLco). The transfer coefficient, calculated as the TLCO divided by the alveolar volume determined by helium dilution during the measurement of TLco, was increased. Pseudo-static compliance curves showed markedly more negative intrapleural pressures at all lung volumes than found in normal people. These results suggest that the circumferential pleural thickening was preventing normal lung expansion despite abnormally great distending pressures. The pattern of lung function tests is sufficiently distinctive for it to be recognised in clinical practice, and suggests that the lungs are held rigidly within an abnormal pleura. The pleural thickening in our patients may have been related to the condition described as "benign asbestos pleurisy" rather than the copyright. interstitial fibrosis of asbestosis.

School ofPathology, Trinity College, Dublin WIDESPREAD recognition of asbestosis dates from the work of Merewether and Price in 1930. They investigated 363 asbestos workers and concluded that there was a pneumoconiosis resulting from asbestos inhalation, that this condition shortened life, and that measures to diminish the atmospheric concentration of asbestos dust would reduce the incidence of the disease. In 1931 asbestosis was accepted as a compensatable disease in Great Britain and steps were taken to reduce the risk in the asbestos industry. 18 years later Wyers (1949) found that the age at death in this disorder had Protected by copyright. increased and that finger-clubbing had become more common. He suggested that these changes were due to a more chronic form of the disease resulting from improved dust control in the industry following the legislation of 1931. Currently however, the number of new cases of asbestosis in Great Britain is increasing, their frequency suggesting an incidence rate of at least five per thousand of those occupation- ally exposed (McVittie, 1965). Though earlier reports indicated that tuberculosis was common in asbestosis (Wyers, 1949; Gloyne, 1951; Bonser, Foulds and Stewart, 1955) it appears to be a rare I 0 n < ,.

GERSON, Judge COLLEEN DUFFY KIKO, Judge JAMES A. HAYNES, Alternate Judge JURISDICTION On October 30, 2007 appellant filed a timely appeal from a November 17, 2006 decision of the Office of Workers’ Compensation Programs denying his occupational disease claim. Pursuant to 20 C.F.R. §§ 501.2(c) and 501.3, the Board has jurisdiction over the merits of the claim. ISSUE The issue is whether appellant has established that he sustained occupational asthma in the performance of duty due to accepted workplace exposures. On appeal, he, through his attorney, asserts that the Office did not provide Dr. William C. Stewart, the impartial medical examiner, with a complete, accurate statement of accepted facts. FACTUAL HISTORY On December 8, 2004 appellant, then a 57-year-old insulator, filed an occupational disease claim (Form CA-2) asserting that he sustained occupational asthma and increasing shortness of breath due to workplace exposures to fiberglass, silicates, welding smoke, polychlorobenzenes, rubber, dusts, gases, fumes and smoke from “burning out” submarines from 1991 through January

  • Cryptococcus Pneumonia Presenting in an Immunocompetent Host with Pulmonary Asbestosis
    Guy et al. Journal of Medical Case Reports 2012, 6:170 JOURNAL OF MEDICAL http://www.jmedicalcasereports.com/content/6/1/170 CASE REPORTS CASE REPORT Open Access Cryptococcus pneumonia presenting in an immunocompetent host with pulmonary asbestosis: a case report Judah P Guy1, Shahzad Raza1,2*, Elliot Bondi1, Yale Rosen2, Dong-Sung Kim2 and Barbara J Berger1 Abstract Introduction: Cryptococcal infections pose a diagnostic challenge in an immunocompetent host. Asbestos exposure has been associated with pulmonary aspergillosis. This case highlights an interesting presentation of cryptococcal lung inflammation with underlying asbestosis. Case presentation: A 63-year-old Mediterranean Caucasian woman presented with progressive dry cough of nine months duration. A computed tomography (CT) scan of her chest revealed multiple foci in the right infra-hilar region, which were seen as hot lung masses on a positron emission tomography (PET) scan. These multiple foci appeared metastatic in nature throughout both lung fields with early mediastinal invasion. A computed tomography (CT)-guided core biopsy was obtained from a dominant right lower lobe lung mass. Histology showed chronic granulomatous inflammation with numerous budding yeast forms that were GMS-, PAS-, and mucin- positive, consistent with cryptococcosis together with asbestos bodies (ferruginous). She was managed with fluconazole (400mg (6mg/kg) per day orally) daily. At her six-month follow up, she had marked improvement in her general condition along with a diminution of the lower lobe lung mass. Conclusion: We report a clinical and radiological improvement in a patient treated for cryptococcal pneumonia. Asbestos exposure was likely to have been an important pathophysiological precursor to infection by environmental fungi.

  • Asbestos Safety Manual
    Asbestos Safety Manual D. Potential Health Effects Related to Asbestos Routes of Entry While asbestos fibers may gain entry into the body through ingestion, the major route of exposure is inhalation. Asbestos fibers have no odor, and those that you may inhale are invisible to the naked eye. The Respiratory System The respiratory system includes the mouth, nose, wind pipe (trachea), bronchi, and lungs. The lungs are located within the pleural cavity. Lying within the cavity and covering the lungs is a lining called the pleural mesothelium. The lungs contain air sacks called alveoli. The alveoli are the sites where oxygen is absorbed into the blood and carbon dioxide is removed from the blood. The body’s respiratory system has defense mechanisms to keep foreign particles from causing damage. Amazingly, estimates indicate that these mechanisms are 95 to 98 percent effective. Examples of some defense mechanisms and their functions are: • The mouth and nose filter out very large particles. • Coated bronchi filter out smaller particles. • Cilia, which are hair-like protrusions on cells lining the airways (bronchial tree), move particles up to the back of the mouth where they are swallowed or expelled. • Alveoli in the lower respiratory system trap the smallest particles. The particles may be attacked by large cells, known as macrophages, which try to digest them. Because asbestos is a mineral fiber, the macrophages are often not successful. Asbestos Health Risks Most of the information about asbestos disease comes from studying workers in the various asbestos industries. The bulk of data comes from World War II shipbuilding activities and the asbestos industries in the United States and England.

Learn the current diagnosis and treatment for inhalation pulmonary diseases due to exposure to air pollution. Exposure to air pollution is associated with numerous effects on human health, including pulmonary, cardiac, vascular, and neurological impairments. The health effects vary greatly from person to person. High-risk groups such as the elderly, infants, pregnant women, and sufferers from chronic heart and lung diseases are more susceptible to air pollution. Children are at greater risk because they are generally more active outdoors and their lungs are still developing. Exposure to air pollution can cause both acute (short-term) and chronic (long-term) health effects. Acute effects are usually immediate and often reversible when exposure to the pollutant ends. Some acute health effects include eye irritation, headaches, and nausea. Chronic effects are usually not immediate and tend not to be reversible when exposure to the pollutant ends. Some chronic health effects include decreased lung capacity and lung cancer resulting from long-term exposure to toxic air pollutants. The scientific techniques for assessing health impacts of air pollution include air pollutant monitoring, exposure assessment, dosimetry, toxicology, and epidemiology. Although in humans pollutants can affect the skin, eyes and other body systems, they affect primarily the respiratory system. Air is breathed in through the nose, which acts as the primary filtering system of the body.

  • Work-Related Lung Diseases
    American Thoracic Society PATIENT EDUCATION | INFORMATION SERIES Work-Related Lung Diseases Most types of lung disease can be caused by work exposures including: asthma, chronic obstructive pulmonary disease (COPD), interstitial lung diseases, lung cancer, pulmonary infections, and pleural disease. It is important to recognize whether exposures in your workplace are contributing to your lung disease because often steps can be taken to prevent the lung disease or keep it from progressing. If you are having problems, there may be other workers who can look just like sarcoidosis. Other metals such as indium, are also at risk for the disease.

  • Advances in the Diagnosis and Management of Pulmonary Aspergillosis
    REVIEW Yuqing Gao, Ayman O. Soubani Division of Pulmonary, Critical Care and Sleep Medicine, Wayne State University School of Medicine, Detroit, USA Advances in the diagnosis and management of pulmonary aspergillosis Abstract Aspergillus is a mould that is ubiquitous in nature and may lead to a variety of infectious and allergic diseases depending on the host’s immune status or pulmonary structure. Invasive pulmonary aspergillosis occurs primarily in patients with severe immuno- deficiency. The significance of this infection has dramatically increased with growing numbers of patients with impaired immune state associated with the management of malignancy, organ transplantation, autoimmune and inflammatory conditions; critically ill patients appear to be at an increased risk as well. The introduction of new noninvasive tests, combined with more effective and better-tolerated antifungal agents, has resulted in lower mortality rates associated with this infection. Chronic pulmonary aspergillosis is a locally invasive disease described in patients with chronic lung disease or mild immunodeficiency. Recently, the European Society for Clinical Microbiology and Infectious Diseases provided a more robust sub-classification of this entity that allows for a straightforward approach to diagnosis and management. Allergic bronchopulmonary aspergillosis, a hypersensitivity reaction to Aspergillus antigens, is generally seen in patients with atopy, asthma or cystic fibrosis. This review provides an update on the evolving epidemiology and risk factors of the major manifestations of Aspergillus lung disease and the clinical manifesta- tions that should prompt the clinician to consider these conditions. It also details the role of noninvasive tests in the diagnosis of Aspergillus related lung diseases and advances in the management of these disorders.
