Thickening of pulmonary interlobar fissures: exposure-response relationship in crocidolite and amosite miners

Thickening of pulmonary interlobar fissures: exposure-response relationship in crocidolite and amosite miners.

Asbestos (chrysotile, Amosite, Crocidolite, Tremolite, Actinolite, and Anthophyllite)

Asbestos is the generic commercial designation for a group of naturally occurring mineral silicate fibres of the serpentine and amphibole series. These include the serpentine mineral chrysotile (also known as ‘white asbestos’), and the five amphibole minerals – actinolite, amosite (also known as ‘brown asbestos’), anthophyllite, crocidolite (also known as ‘blue asbestos’), and tremolite (IARC, ...

Correlation between collateral ventilation and interlobar lung fissures.

BACKGROUND New bronchoscopic techniques for end-stage emphysema treatment are nowadays available; the presence of interlobar collateral ventilation (CV) and interlobar lung fissures (ILF) is crucial for patient selection. OBJECTIVES Assessment of these variables has been reported previously, but it has never been anatomically validated in vivo. This is the purpose of our study. METHODS Twen...

Emphysema and pulmonary impairment in coal miners: Quantitative relationship with dust exposure and cigarette smoking

Coal miners have been shown to be at increased risk of developing chronic obstructive pulmonary diseases including emphysema. The objective of this study was to determine whether lifetime cumulative exposure to respirable coal mine dust is a significant predictor of developing emphysema at a clinically-relevant level of severity by the end of life, after controlling for cigarette smoking and ot...

Dust exposure and mortality in an American factory using chrysotile, amosite, and crocidolite in mainly textile manufacture.

This report describes the second in a series of three parallel cohort studies of asbestos factories in South Carolina, Pennsylvania, and Connecticut to assess the effects of mineral fibre type and industrial process on mortality from malignant mesothelioma, respiratory cancer, and asbestosis. In the present plant (in Pennsylvania) mainly chrysotile, with some amosite and a small amount of croci...
