AIM: Pneumoconiosis is caused by inhaling dust. The aim of the study was to analyze 208 cases of workers' pneumoconiosis. METHOD: Patients' files were used for the descriptive study. RESULTS: All patients were male aged 38.82±13 years. The most important symptom was breathlessness. Patients were denim sandblasters (50.5%), dental technicians (12%), coal miners (6.7%), and others. The mean exposure time before pneumoconiosis occurred was shorter in denim sandblasters and teflon kitchenware producers compared to other occupations (5...

Occupational lung diseases span a variety of pulmonary disorders caused by inhalation of dusts or chemical antigens in a vocational setting. Included in these are the classic mineral pneumoconioses of silicosis, coal worker's pneumoconiosis, and asbestos-related diseases as well as many immune-mediated and airway-centric diseases, and new and emerging disorders. Although some of these have characteristic imaging appearances, a multidisciplinary approach with focus on occupational exposure history is essential to proper diagnosis...

The H19 is a kind of long noncoding RNA, which has been implicated in multiple biological functions. However, the associations between genetic variants in H19 and susceptibility of coal workers' pneumoconiosis (CWP) have been seldom reported. In the present study, three potential polymorphisms (rs2067051, rs217727, and rs2839702) in H19 were genotyped in a case-control study including 703 CWP cases and 705 controls. We found that individuals with the H19 rs2067051 CT/TT genotypes showed a decreased risk of CWP compared with those with the CC genotype (adjusted OR = 0...

LncRNA-ATB (lncRNA was activated by transforming growth factor-β) has been reported to be involved in specific physiological and pathological processes in human diseases, and could serve as biomarkers for cancers. However, the role of lncRNA-ATB in coal workers' pneumoconiosis (CWP) is still unknown. This study aimed to investigate the association between lncRNA-ATB and CWP. Quantitative real-time polymerase chain reaction was performed to detect plasma lncRNA-ATB expression in 137 CWP patients, 72 healthy coal miners and 168 healthy controls...

Coal workers' pneumoconiosis (CWP) is an untreatable but preventable lung disease arising from chronic inhalation of coal dust. Recent reports of CWP in Queensland, along with international data, suggest that there is a resurgence in pneumoconiosis. The prevalence of CWP varies considerably between countries. In Australia, there is no mandatory reporting system and no national data on the prevalence of CWP. The symptoms and manifestations of CWP vary depending on the composition of the inhaled dust, duration of exposure, stage of disease and host-related factors...

OBJECTIVE: Our study aimed to evaluate ocular findings and structural changes in coal mine workers who were chronically exposed to coal mine dust and diagnosed with pneumoconiosis. METHODS: Ocular findings of 161 eyes of 81 patients diagnosed with pneumoconiosis who had previously worked or are currently working in coal mines were analyzed. Forty-six coal mine workers and sex matched healthy people (n = 20) participated in the study. Workers who had early changes of pneumoconiosis were included in Group 1 (n = 17), workers diagnosed with pneumoconiosis were included in Group 2 (n = 29), and healthy subjects were included in Group 3 (n = 20)...

PURPOSE: Coal workers' pneumoconiosis (CWP) is caused by an accumulation of coal particles in the lung parenchyma. Reactive oxygen species (ROS) play an important role in the pathogenesis of CWP. It is well documented that ROS stimulate platelet activation, adhesion, and aggregation. The aim of the present study was to investigate the relationship between platelet indices and CWP. METHODS: The demographic features, occupational and medical history, exposure time, and complete blood count of retired coal miners were retrospectively analysed...

This research was aimed at estimating possible Coal workers' pneumoconiosis (CWP) cases as of 2012, and predicting future CWP cases among redeployed coal workers from the Fuxin Mining Industry Group. This study provided the scientific basis for regulations on CWP screening and diagnosis and labor insurance policies for redeployed coal workers of resource-exhausted mines. The study cohort included 19,116 coal workers. The cumulative incidence of CWP was calculated by the life-table method. Possible CWP cases by occupational category were estimated through the average annual incidence rate of CWP and males' life expectancy...

OBJECTIVES: The aim of the study was to determine ventilatory function in a group of patients with silicosis and coal workers pneumoconisos (CWP) newly granted as occupational disease. METHODS: The authors have undertaken the analysis of all cases of occupational silicosis and CWP which were diagnosed in men in the South Moravia region. Information on ventilatory function, chest symptoms, age, working and smoking history was collected during the medical surveys, including spirometry testing and chest radiography...

PURPOSE OF REVIEW: Coal mine workers are at risk for a range of chronic respiratory diseases including coal workers' pneumoconiosis, diffuse dust-related fibrosis, and chronic obstructive pulmonary disease. The purpose of this review is to describe coal mining processes and associated exposures to inform the diagnostic evaluation of miners with respiratory symptoms. RECENT FINDINGS: Although rates of coal workers' pneumoconiosis declined after regulations were enacted in the 1970s, more recent data shows a reversal in this downward trend...

BACKGROUND: The prevalence of coal workers' pneumoconiosis (CWP) in U.S. coal miners has increased, and severe presentations are increasingly common. METHODS: We describe trends in lung transplantation during 1996-2014 for recipients with a primary diagnosis of CWP or pneumoconiosis unspecified, and we summarize recipient characteristics and estimate survival. RESULTS: A total of 47 transplants were included; nearly three-quarters were performed during 2008-2014...

Occupational lung disease is a category of disease entities characterized by a reaction of the lung parenchyma to inhaled aerosolized particles found in the environment. This document summarizes the imaging appropriateness data for silicosis, coal worker pneumoconiosis, and asbestosis. The main points of the document are that computed tomography is more sensitive than radiography, computed tomography without contrast generally suffices for evaluation, and fluorodeoxyglucose-positron emission tomography may have utility in patients with mesothelioma...

Coal miners are exposed to a wide range of genotoxic agents that can induce genome damage. In addition, miners are characterised by a high risk of the initiation of different occupational inflammatory as well as non-inflammatory diseases. The aim of this investigation is to analyse the modifying influence of occupational pulmonary inflammatory diseases on the level of chromosome aberrations (CAs) in miners working in underground coal mines in Kemerovo Region (Russian Federation). The study group included 90 coal miners with the following pulmonary diseases: chronic dust-induced bronchitis (CDB) and coal-workers' pneumoconiosis (CWP) (mean age = 53...
