Asbestos fibers in the general population
…pleura. Counts did not differ significantly by sex or smoking. The authors concluded that substantial asbestos, mostly too small to form asbestos bodies, is present in the average urban lung and probably reflects general environmental contamination.

Asbestos fibers and pleural plaques in a general autopsy population
It has been claimed that symmetric lower zone pleural or diaphargmatic plaques are markers of asbestos exposure both in asbestos workers and the general population. In this study, total pulmonary asbestos burden was analyzed for 29…

Nonasbestos pulmonary mineral fibers in the general population
…sex, or smoking. It is concluded that (1) substantial numbers of nonasbestos fibers are present in lungs of the general population. Most of these fibers are short and of low aspect ratio; and (2) by phase…

Analysis of the cores of asbestos bodies from members of the general population: patients with probable low-degree exposure to asbestos
…to 9,000 of such bodies/g of lung tissue, a concentration frequently found in manual laborers in the general population who are not primary asbestos workers. All of the 123 bodies examined by electron diffraction…

Fiber size and number in workers exposed to processed chrysotile asbestos, chrysotile miners, and the general population
…chrysotile ore, 20 long-term chrysotile miners, and 20 members of the general population (controls). Significantly greater amounts of both chrysotile and tremolite were found in processed-ore workers and miners than in controls. On average…

Utility of BAP1 Immunohistochemistry and p16 (CDKN2A) FISH in the Diagnosis of Malignant Mesothelioma in Effusion Cytology Specimens
…two tests could help diagnose malignant mesothelioma from fluid drained from the chest or abdomen (effusion cytology) instead of tissue biopsy. From Vancouver General Hospital files, the authors took 15 patients with epithelial mesothelioma (13 pleural…

Re: Mesothelioma in railroad machinists
…800,000 tremolite fibers per gram of dry lung. The general-population 95th percentile for amosite plus crocidolite was 10,000 fibers per gram of dry lung. The authors stated that the amosite plus crocidolite values…

Malignant mesothelioma caused by childhood exposure to long-fiber low aspect ratio tremolite
…his later work. The authors dissolved lung tissue and examined the recovered fibers by electron microscope. His chrysotile level was within the general population's range. His tremolite and actinolite level was slightly elevated, but far…

Fiber size and number in amphibole asbestos-induced mesothelioma
…of crocidolite fibers, 0.2 X 10(6)/g; these values represent an approximately 250-fold increase over those found in the general population. Crocidolite fibers were significantly narrower than amosite fibers (mean width, 0.13…

Current issues in the pathologic and mineralogic diagnosis of asbestos-induced disease
…as the main problem. The author wrote that a million chrysotile fibers per gram of dry lung fit general-population background levels. A million amosite or crocidolite fibers per gram almost certainly indicated substantial occupational exposure…

Nonoccupational exposure to chrysotile asbestos and the risk of lung cancer
…and crocidolite fibers per gram of dry lung. The laboratory's maximal general-population background for amosite plus crocidolite is 10,000 fibers per gram of dry lung. The second and third had asbestosis at autopsy…

Analysis of lung asbestos content
…In the author's laboratory the upper 95th percentile for the Vancouver general population was around 1 000 000 fibres each of chrysotile and tremolite and 10 000 fibres of amosite plus crocidolite per g of…

Asbestos and other ferruginous bodies: their formation and clinical significance

Utility of a CEA, CD15, calretinin, and CK5/6 panel for distinguishing between mesotheliomas and pulmonary adenocarcinomas in clinical practice

The Canadian Immunohistochemistry Quality Control program circulates tissue array slides to…
