The incidence of asbestos bodies in the lungs at random necropsies in Montreal

Canadian Medical Association Journal
L Anjilvel, W M Thurlbeck


The incidence of asbestos bodies in the lungs of adult patients selected at random, who died in four Montreal hospitals, was studied by examining fresh unstained smears of lungs obtained at necropsy. Two techniques were used for preparation of the smears and an arbitrary grading system was developed to estimate the degree of contamination of the lungs by asbestos bodies.Asbestos bodies were present in 48 out of 100 necropsies; they were found in 32 of 56 men (57%) and in 16 of 44 women (34%). Men were more heavily contaminated. The proportion of positive smears depended on the technique used and the amount of lung sampled. No particular association was noted between asbestos bodies in the lungs and the presence of cancer in the 33 patients in this series with malignant disease. The high incidence in this random series suggests that asbestos is a significant air contaminant in Montreal.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
