Opis:
Introduction: Pneumoconioses (Pc) are interstitial pulmonary diseases of professional genesis, caused by long-term inhalation of high dust concentrations. Pcafflict 26.6-53% of the workers, exposed to dust contamination. The major feature of Pc course is irrevocability and incurability. Purpose: The research of the effect of ethylmethyl hydroxypyridine succinate, possessing antioxidant and antihypoxant characteristics, on the oxygen metabolism, acid-alkaline state, and lipid peroxidation at the background of experimental pneumoconiosis in albino rats. Material and methods: Pneumoconiosis was simulated on 72 albino rats through endotracheal injection of black coal suspension, on our own modification of O. Yu. Nykolenko methodology. Results: Manifestations of experimental pneumo-coniosis depended on the period of dust inhalation. Development of experimental pneumoconiosis was found to result in the decreased partial oxygen pressure in the arterial blood, compensated hyperventilation-induced respiratory alkalosis, and marked increase in lipid peroxidation activity that could be seen in the blood content of malon-dialdehyde, as well as of conjugated dienes and trienes. Conclusions: Application of ethylmethylhydroxy pyridine succinate in experimental pneumoconiosis has been found to improve oxygen metabolism, acid-alkaline state, and lipid peroxidation that is revealed in normalization of the partial oxygen pressure in the arterial blood, oxygen saturation of haemoglobin, index of bases’ deficiency BE (Ваse-Ехсеss), and in 1.6-2.0 decrease in the content of malondialdehyde, as well as of conjugated dienes and trienes.

Opis:
Objectives: The aim of this 7-year follow-up study was to determine respiratory changes in dental technicians. Material and Methods: In our region, in the year 2005, 36 dental technicians were evaluated with a cross-sectional study on respiratory occupational diseases, and in 2012 we evaluated them again. Inclusion of information on respiratory symptoms and demographic features questionnaires was applied. Pulmonary function tests (PFT) were performed. Chest X-rays (CXR) were evaluated according to the ILO-2000 classification. For the comparisons of the technicians' findings in 2005 and 2012, data analyses were performed with the Wilcoxon test in addition to descriptive statistical procedures. Results: In 2012, 19 out of the 36 technicians continued to work in the same place, so we were able to evaluate their findings. The prevalence of respiratory symptoms in dental technician was as follows: dyspnea 7 (37%), cough 6 (32%), and phlegm 5 (26%). According to ILO classifications in 2005, among the 36 technicians, 5 (13.8%) had pneumoconiosis. At the end of 7 years, there were 9 pneumoconiosis cases among the 19 remaining technicians (47%). Thus, there was a statistically significant progression on the profusion of the radiologic findings (p < 0.005). Also there was a significant worsening on spirometric findings (p < 0.05). Conclusion: In dental technicians, a determination of both radiologic and functional progressions at the end of 7 years demonstrate that the primary and secondary preventive measures are necessary for these workplaces. Workplaces must be regularly controlled for worker health and hygiene.

Opis:
Objective: The aim of the study was comparison of cancer incidence risk of lungs, stomach, colon, bladder and kidneys from ex-miners of black coal mines and the general male population of the Czech Republic. Materials and methods: The analysis was conducted in two cohorts of ex-miners according to the presence of coalworkers’ pneumoconiosis (CWP). The first cohort included the miners without CWP (N = 6705), and the second cohort included the miners who were compensated for CWP (N = 2158). Personal and occupational data was merged with the data in the National Population Register and the National Oncological Register for the period from 1992 to 2006. Cancer risk in miners in comparison to the general male population of the Czech Republic was evaluated by SIR (Standardized Incidence Ratio) and 95% confidence interval (CI). Results: About twice as high risk of lung cancer was found in miners with CWP (SIR = 2.21; 95% CI: 1.75–2.76). Lung cancer risk correlated with the severity of CWP (simple CWP SIR=1.96; 95% CI: 1.48–2.56, progressive massive fibrosis SIR = 4.29; 95% CI: 2.09–7.87). No increased risk of lung cancer was found in ex-miners without CWP. The risk of malignant neoplasm at the other selected sites was comparable with the risk in the general male population of the Czech Republic. Conclusions: This study found increased lung cancer risk in coal miners with CWP, but not in those without CWP, comparing with the general population. These results served as the basis for the inclusion of lung cancer in association with CWP into a new Czech list of occupational diseases.

Opis:
Statistical data on occupational diseases registered by the Institute of Occupational Medicine in Łódź indicates a renewed increase in the number of pneumoconiosis in Poland in recent years, especially in the section of PKD (Polish Classification of Business Activities) – mining. Simultaneously, in 2018, because of the implementation of Directives of the European Parliament and the Council of the European Union, changes were introduced to Polish legislation in the field of protection of workers against the risk of exposure to carcinogens or mutagens related to the respirable fraction of crystalline silica formed during work. Considering this information, the members of the Department of Safety Engineering of the Silesian University of Technology attempted to assess the dust hazard and the frequency of occurrence of respiratory diseases among the employees of the preparation plant of mine X exposed to the harmful effects of industrial dust produced in the work process. The following methods were used as part of the research: individual dosimetry, infrared spectrometry, directional interview, diagnostic tests, and spirometry. The obtained results made it possible to identify workstations with the highest exposure to the harmful effects of industrial dust and to recognize the impact of this action in the form of pathological changes in the respiratory system in 18.4% of the miners surveyed

Introduction: Information on the changes of pulmonary function and the right cardiac structure in patients with coal worker’s pneumoconiosis in China is very scarce. This study was performed to clarify the changes of pulmonary function and right cardiac structure in patients with coal worker’s pneumoconiosis in China. Material and methods: Pulmonary function, pulmonary artery systolic pressure, and the right cardiac structure were evaluated by spirometry and color Doppler echocardiography. Results: The pulmonary artery systolic pressure of patients with coal worker’s pneumoconiosis was increased with disease severity. Patients with coal worker’s pneumoconiosis also exhibited an impaired pulmonary function and altered right cardiac structure compared with control subjects. A significant linear correlation of the variables of pulmonary ventilation and diffusion function with the indicators of the right cardiac structure was found in patients with coal worker’s pneumoconiosis in China. Conclusions: This study elucidated a deterioration of pulmonary function and right cardiac structure in patients with coal worker’s pneumoconiosis in China.

Objectives: To explore the rate of pneumoconiosis in dental technicians (DTP) and to evaluate the risk factors. Material and Methods: Data of 893 dental technicians, who were admitted to our hospital in the period January 2007–May 2012, from 170 dental laboratories were retrospectively examined. Demographic data, respiratory symptoms, smoking status, work duration, working fields, exposure to sandblasting, physical examination findings, chest radiographs, pulmonary function tests and high-resolution computed tomography results were evaluated. Results: Dental technicians’ pneumoconiosis rate was 10.1% among 893 cases. The disease was more common among males and in those exposed to sandblasting who had 77-fold higher risk of DTP. The highest profusion subcategory was 3/+ (according to the International Labour Organization (ILO) 2011 standards) and the large opacity rate was 13.3%. Conclusions: To the best of our knowledge, it was the largest DTP case series (N = 893/90) in the literature in English. Health screenings should be performed regularly for the early diagnosis of pneumoconiosis, which is an important occupational disease for dental technicians.

Opis:
BackgroundCancer risk (especially as regards lung cancer) in black-coal miners is mainly analyzed on the basis of mortality. The risk calculated based on mortality may differ from the values based on incidence. The aim of the study was to compare cancer risk in black-coal miners with and without coal workers’ pneumoconiosis (CWP), based on data on mortality and the incidence of lung cancer in the Czech Republic in 1992–2013.Material and MethodsThe cohort without CWP was composed of 6687 miners, and the cohort with CWP of 3476 miners. Information on the incidence of lung cancer was obtained from the Czech National Oncological Register (NOR), and information on mortality from the National Population Register. The risk of lung cancer incidence was compared with the general male population in the Czech Republic using the standardized incidence ratio (SIR), and the risk of lung cancer mortality using the standardized mortality ratio (SMR), with the 95% CI.ResultsIn miners with CWP, a lower SMR value was found, SMR = 1.70 (95% CI: 1.41–2.04), compared with the SIR value, SIR = 2.01 (95% CI: 1.70–2.36). In miners without CWP, this was opposite, the value of SIR = 0.81 (95% CI: 0.69–0.94) was lower than the value of SMR = 0.83 (95% CI: 0.70–0.98). In miners without CWP, 17 cases of lung cancer (out of 176 cases in total) were not registered in NOR. In miners with CWP, the share of not registered cases was significantly lower (p = 0.018), and it was represented by 3% of not registered lung cancer cases, out of 156 cases with the diagnosis of lung cancer.ConclusionsIn spite of the difference between SIR and SMR, the results of both indicators were consistent with the resulting relationship between the lung cancer risk and CWP.

Opis:
Statistical data on occupational diseases recorded by the Institute of Occupational Medicine in Lodz, Poland, indicate a renewed increase in the number of cases of pneumoconiosis in Poland in recent years, especially in the PKD section of mining and quarrying industries. At the same time, in 2018 as a result of the implementation of directives of the European Parliament and the Council of the European Union, the changes were introduced to the Polish legislation in the area of protection of workers from the risk of exposure to carcinogenic or mutagenic agents related to the respirable fraction of crystalline silica found, among others, in mine dust. As a result of these solutions, since 2020 we have seen a spike in the number of miners employed in conditions of risk of carcinogenic dust. These facts indicate that despite the wide measurement of harmful factors in coal mines, the effectiveness of preventive measures taken does not bring tangible benefits, and OSH services have problems with the proper assessment of industrial dust hazards at workplaces. In the article, based on surveys, diagnostic (health) tests of workers and verification of the risk assessment methods used, the authors try to point out the most common mistakes made in estimating the level of risk associated with exposure to industrial dust.
