Pleural anthracosis as an indicator of lifetime exposure to urban air pollution: An autopsy-based study in Sao Paulo.

Environ Res 2019 Mar 4;173:23-32. Epub 2019 Mar 4.

Universidade de Sao Paulo Medical School (FMUSP), Sao Paulo, Brazil.

Many studies have been conducted to evaluate the association between air pollution and adverse health effects using a wide variety of methods to assess exposure. However, the assessment of individual long-term exposure to ambient air pollution is a challenging task and has not been evaluated in a large autopsy study. Our goal was to investigate whether exposure to urban air pollution is associated to the degree of lung anthracosis, considering modifying factors such as personal habits, mobility patterns and occupational activities.

James Craufurd Gregory, 19th century Scottish physicians, and the link between occupation as a coal miner and lung disease.

J R Coll Physicians Edinb 2017 Sep;47(3):296-302

K Donaldson, Surgeons' Hall Museums, Royal College of Surgeons of Edinburgh, Nicolson Street, Edinburgh EH8 9DW, UK. Email:

By the mid-19th century about 200,000 miners were employed in a UK coal mining industry still growing with the advances of the Industrial Revolution. Coal miners were long known to suffer poor health but the link to inhaling dust in the mines had not been made. In 1813 George Pearson was the first to suggest that darkening of lungs seen in normal individuals as they aged was caused by inhaled soot from burning oil, candles and coal, which were the common domestic sources of heat and light.

With interest, I read the recent analysis by Tomaskova and co-workers (2017) about mortality from coal workers' pneumoconiosis (CWP). The research question remains unclear whether coal workers' pneumoconiosis (CWP) resulting from exposure to respirable coal dust containing crystalline silica accelerates the development of lung cancer or whether it is an intermediate stage in the pathway. I made several points of considerations with respect to (1) qualified data; (2) alternate measures for excessive risks; and (3) methodological flaws that should be avoided. Read More

Element-based prognostics of occupational pneumoconiosis using micro-proton-induced X-ray emission analysis.

Am J Physiol Lung Cell Mol Physiol 2017 Dec 14;313(6):L1154-L1163. Epub 2017 Sep 14.

Department of Pneumoconiosis, Occupational Disease Clinical Research Centre, Department of Radiotherapy, Central Laboratory, Department of Pathology, Shanghai Pulmonary Hospital, Tongji University School of Medicine, Shanghai, China;

Pneumoconiosis is an occupational disease accompanied by long-term lung impairment, for which prediction of prognosis is poorly understood because of the complexity of the inhaled particles. Micro-proton-induced X-ray emission (micro-PIXE) analysis, which is advantageous for high-sensitivity, two-dimensional element mapping of lung tissues, was used to investigate element-based predictive factors of prognosis in Chinese patients with welder's and coal miner's pneumoconiosis. Chest radiographs and lung function tests showed that most of the coal miners deteriorated, whereas symptoms in some welders were alleviated after 5 yr, as determined by comparing percent vital capacity (%VC) and forced expiratory volume in the 1st second over forced vital capacity (FEV1.

State-of-the-art nanopathological diagnostics.

Ultrastruct Pathol 2017 Sep-Oct;41(5):309-311. Epub 2017 Aug 14.

a Department of Diagnostic and Clinical Medicine and of Public Health , University of Modena and Reggio Emilia , Modena , MO , Italy.

The nanopathological diagnostics (ND) is an ultra-specialized branch of pathological anatomy aimed to identify the nanoparticles of metallic, semimetallic, or nonmetallic elements in the inorganic particulate matter present inside pathological tissues, even on the nanometer scale. ND exploits an environmental scanning electron microscope, connected to an X-ray microprobe mounted on an energy-dispersive spectrometer. The searching of nanoparticles can be performed on paraffin-embedded material, omitting emissions of black overlay and plating procedures. Read More
