In plain English

This was a letter to the editor, not a research study, and it reported no new data. The author argued that the ILO classification, a standard system for reading chest X-rays for dust-related lung disease, should record asbestos-related changes of the visceral pleura (the lining covering the lung) separately from changes of the parietal pleura (the lining of the chest wall). Citing earlier studies, the author stated that diffuse pleural thickening, without lung scarring, results in impaired lung function, while pleural plaques alone are not recognized as causing significant impairment. The author noted that the type of pleural change can determine compensation eligibility. According to the author, thickening of the lung fissures appeared only in the subset of symbols. Pleural strand formation could be recorded only under "comments" in the 1980 edition and 1997 draft. Rounded atelectasis fell outside the main section for pleural changes. The author warned that linear calcification along the chest wall could be misread as plaque calcification. The author concluded that visceral pleural changes deserve separate inclusion in any revised ILO classification.

What the study did and found

• Design: Letter to the editor (opinion/commentary); no original data
• Main results:
  • Citing earlier studies, the author stated that diffuse pleural thickening without parenchymal fibrosis results in impaired lung function, while pleural plaques alone are not recognized as being associated with significant respiratory impairment
  • The author stated that the nature of the pleural changes can determine a worker's eligibility for compensation
  • The author argued that thickening of the interlobar fissures is currently relegated to the subset of symbols in the ILO classification rather than its main body
  • The author noted that pleural strand formation is not addressed in the 1980 revised edition or the 1997 revised draft and can be recorded only under "comments"
  • The author argued that diffuse linear calcification along the lateral chest wall could be misinterpreted as plaque calcification
  • The author noted that rounded atelectasis (folded lung) is recorded outside the main body of the ILO section for pleural changes
  • The author argued that separating benign parietal pleural changes from visceral pleural changes is necessary because the latter can be associated with lung function impairment
• The authors' conclusion: The author concluded that asbestos-related visceral pleural manifestations deserve separate inclusion in any revised ILO classification
