BACKGROUND Lipid peroxidation plays an important role in the pathogenesis of pneumoconiosis. Volatile organic compounds (VOCs) generated from lipid peroxidation might be used to detect pneumoconiosis. The objective of this study was to develop a breath test for pneumoconiosis. METHODS A case-control study was designed. Breath and ambient air were analysed by gas chromatography/mass spectromet...

The pneumoconiosis of coalminers is a primary disorder of the lungs that can cause pulmonary heart disease, a condition also called cor pulmonale. The occurrence of right heart changes in pneumoconiosis was noted by Pancoast and Pendergrass (1931). Dyson (1933 and 1934) described the radiological recognition of heart disease in pneumoconiosis, and in a review of 127 cases found 18 with evidence...

One of the tasks of the Pneumoconiosis Research Unit has been to try to relate the incidence of pneumoconiosis to the environment in which it has developed. In surveys in coal-mines, the incidence of pneumoconiosis among the miners has been measured by x-ray examinations; in addition, detailed industrial histories and measurements of the miners' dust exposure have been collected. In this paper ...

Sadler, R. L. (1974). Thorax, 29, 699-702. Attributability of death to pneumoconiosis in beneficiaries. Coal workers and slate workers who were receiving in 1965 industrial disability benefit for pneumoconiosis were grouped according to the radiological extent of their disease and their disability assessment. They were followed up for 7-5 years. Standard mortality rates, and from these the perc...

We have been developing a computer-aided detection (CAD) scheme for pneumoconiosis based on a rule-based plus artificial neural network (ANN) analysis of power spectra. In this study, we have developed three enhancement methods for the abnormal patterns to reduce false-positive and false-negative values. The image database consisted of 2 normal and 15 abnormal chest radiographs. The Internation...

Abstract Pneumoconiosis is a disease characterized by pulmonary tissue deposition caused dust exposure in the workplace. In China, due to large number and wide distribution of pneumoconiosis patients, there high demand for case data lung biopsy during diagnosis pneumoconiosis. This text studied application medical image detection technology based on deep learning (DL). A convolution neural netw...

According to scientific statistical information that occupational pathology includes a number of diseases are undesirable consequences the working area and nature work. One these is pneumoconiosis. Despite improvements in mining technology, majority miners work adverse conditions. The problem pneumoconiosis continues be relevant, both interests vast key economies world for Republic Uzbekistan. ...

OBJECTIVE To investigate if blood Cu++/Zn++ superoxide dismutase, glutathione peroxidase, catalase, and total plasma antioxidant activities could be markers of biological activity resulting from exposure to respirable coal mine dust in active miners, and of pneumoconiosis in retired miners. METHODS Blood samples were randomly obtained from active surface workers (n = 30) and underground miner...

Results from a correlation survey which compared radiological and physiological findings during life with detailed morbid anatomical findings in the lungs of 247 deceased miners and ex-miners with pneumoconiosis were used to assess the extent and significance of their pulmonary disability.Coal workers' pneumoconiosis usually caused progressive impairment of ventilation, which in the simple type...

During the past 20 years number of definitive occupational diseases has not increased above 1500 case/year according to official statistics in Turkey. Although pneumoconiosis is the most diagnosed occupational disease, incidence of pneumoconiosis is very low.The present paper aims at reaching conclusions on the true dimension of the pneumoconiosis problem by evaluating whole the studies and cas...
