Diagnosis of asbestos-related lung diseases.

Expert Rev Respir Med 2019 03 25;13(3):241-249. Epub 2019 Jan 25.

a Department of Respiratory Medicine , Sir Charles Gairdner Hospital , Perth , WA , Australia.

Introduction: The diagnosis of lung disease in asbestos-exposed individuals is a process that not only requires a detailed occupational and tobacco smoking history, but the correlation with physical signs, appropriate imaging, detailed lung function assessment and histology/cytology when required. Worldwide, the total quantity of asbestos mined is static, having decreased dramatically in developed countries but increased in countries where there is no restriction on mining: for example, Russia, China, Brazil, and Kazakhstan. The predominant diagnostic challenge in most cases of possible asbestos-related disease is the significant interval between exposure and development of the disease. Read More

Diffuse pleural thickening following heart failure-related pleural effusions in an asbestos exposed patient.

Int J Occup Environ Health 2015 13;21(2):169-71. Epub 2015 Jan 13.

Diffuse pleural thickening (DPT) is a well-recognized consequence of asbestos exposure and often follows a benign asbestos-related pleural effusion. At our tertiary center, in the North West of England where the prevalence of asbestos-related pleural disease is high, we have encountered a series of patients that have had led us to consider a new hypothesis in DPT. We postulate that non-asbestos-related pleural effusions, particularly transudative pleural effusions, caused by heart failure can trigger the development of DPT. Read More
