Asbestosis and small cell lung cancer in a clutch refabricator
A case of asbestosis and small cell lung cancer in a clutch refabricator is described. Exposed surfaces of used clutches similar to those refabricated in the worker's workplace were rinsed, and the filtrate analysed by analytical transmission electron microscopy. Tissue samples were also analysed by this technique. Numerous chrysotile fibres of respirable dimensions and sufficient length to form ferruginous bodies (FBs) were detected from rinsed filtrates of the clutch. Bronchoalveolar lavage fluid contained many FBs, characteristic of asbestos bodies. Necropsy lung tissue showed grade 4 asbestosis and a small cell carcinoma in the right pulmonary hilum. Tissue analysis by light and analytical electron microscopy showed tissue burdens of coated and uncoated asbestos fibres greatly exceeding reported environmental concentrations (3810 FBs/g dry weight and 2,080,000 structures ≥0.5µm/g dry weight respectively). 72% of the cores were identified as chrysotile. In conclusion, clutch refabrication may lead to exposure to asbestos of sufficient magnitude to cause asbestosis and lung cancer.

Pulmonary dysfunction in silica-exposed workers: A relationship to radiographic signs of silicosis and emphysema
To compare the contribution of silicosis and emphysema with pulmonary dysfunction, radiographic signs of silicosis and emphysema in workers at a Chinese refractory plant were analysed. Radiographic hyperinflation was detected in 9% of the workers without silicosis and in 33% of the workers with silicosis. Silicosis was significantly associated with hyperinfiation after adjusting for exposure duration, age and smoking. Respiratory symptoms were more frequent in the more severe cases of silicosis. Silicosis was significantly associated with decreases in the parameters of pulmonary function, but the significance disappeared when the hyperinflation term was added to the models. Radiographic hyperinflation was strongly associated with decreases in FEV1 and FEV1/FVC while relevant factors were controlled. Comparison between workers with and without hyperinflation showed that the former had significantly lower pulmonary function values. Emphysema associated with silicosis is likely to be responsible for pulmonary obstruction and decreased diffusing capacity occurring in silica-exposed workers.

Occurrence and prevention of coal miners' pneumoconiosis in Poland
Coal production is one of the largest industries in Poland and incidence of coal miners' pneumoconiosis is high. Epidemiological data are derived from the national register of occupational diseases and from previous investigations performed in Poland. Analysis of dust concentration measurements shows that occupational exposure limits are exceeded in 90% of underground workplaces. The number of new pneumoconiosis cases diagnosed annually ranges from 400 to 800 and has been showing a diminishing tendency in the last five years. Recently, a new system of medical and technical prevention has been introduced in seven collieries. Nevertheless pneumoconiosis prevention needs to be improved throughout the sector.

Airborne microflora in Quebec dairy farms: Lack of effect of bacterial hay preservatives
Air samples were collected from 19 barns in Quebec using bacterial hay treatment (inoculation of a lactic-acid producing bacterium in hay to prevent deterioration) and from 18 control barns. Airborne contaminants measured included total bacteria, moulds, endotoxins and Saccharopolyspora rectivirgula, the causative agent for farmer's lung. Since no significant difference was observed in any of the contaminants in the treated and untreated barns, this type of hay treatment probably does not protect farmers from the respiratory effects of ambient microbial contaminants. Topics: bacterial toxins; dairy farming; determination in air; farmer's lung; hay; microorganisms; moulds.

Respiratory symptoms and pulmonary function in coal miners: Looking into the effects of simple pneumoconiosis
Pulmonary function was measured in 205 miners with simple coal workers' pneumonconiosis (CWP) and in 289 without X-ray evidence of pneumoconiosis. A questionnaire on occupational history and respiratory symptoms including breathlessness, chronic cough, and phlegm was administered. The presence or absence of emphysema on X-ray films was also evaluated. On average, the miners with CWP had lower values of pulmonary function and higher prevalences of respiratory symptoms and emphysema than did those without. The simple CWP was associated with increased risk of the respiratory symptoms after adjusting for age, smoking, and years underground. Even when the effects of emphysema and respiratory symptoms indicating chronic bronchitis were taken into consideration, the significant relationship between CWP and decrements in forced vital capacity and diffusing capacity remained. Findings are consistent with simple CWP being a contributor to significant decrements in pulmonary function, and to increased risk of respiratory symptoms. Topics: age-linked differences; chest radiography; China; chronic respiratory diseases; coal dust; coal mining; coalworkers pneumoconiosis; emphysema; epidemiologic study; length of exposure; pulmonary function; smoking; spirometry.

Metal working fluid-associated hypersensivity pneumonitis: An outbreak investigation and case-control study
Occupational exposure to bacterial or fungal antigens has been associated with hypersensivity pneumonitis (HP), an immunologically-mediated pulmonary disease. 34 employees working in machining and assembly areas of an engine manufacturing plant were clinically diagnosed with HP. Of these, 20 employees met an epidemiologic case definition. In a case-control study, no exposure variables, including duration and intensity of metal working fluid (MWF) exposure, were statistically associated with an increased risk of disease. Neither cases nor controls demonstrated precipitin reactivity against unused samples of the seven MWF and two biocides used in the plant. HP cases had a significantly higher prevalence of positive precipitin reactions to used oil-soluble and synthetic MWFs. Reactivity to used but not unused MWF suggests a biocontaminant, probably bacteria or fungi, is the causative antigen in the development of HP in this setting. Topics: allergens; antigens; bacteria; biocides; case-control study; cutting fluids; extrinsic allergic alveolitis; fungi; motor vehicle industry; pulmonary function; serological reactions; serum precipitins; used oils.

Risk of silicosis in coalworkers exposed to unusual concentrations of respirable quartz
Chest radiographs were taken from 547 men who had worked at a colliery during the 1970s. Classifications of these films under the International Labour Organisation (ILO) 1980 scheme were related to existing data on individual men's exposures to respirable dust and quartz. 203 men (38%) showed progression of at least one profusion category on the 12-point scale, from the various 1970s surveys to the follow up in 1990-1. 158 men (29%) had a profusion of at least 1/0, and 47 (8.6%) of at least 2/1 at the follow up survey. Large opacities were recorded by at least two readers for 14 (2.6%) of the men. Profusion of small opacities was strongly related to exposures experienced in the 1970s, and more strongly for quartz than for the non-quartz fraction of the dust. Estimates of risk are presented over the range of quartz exposures experienced. The quartz exposures experienced by some men at this colliery have caused considerable progression of radiographic abnormalities since exposure ended.

Quartz exposures and severe silicosis: A role for the hilar nodes
Two stonemasons working together in an environment with high concentrations of quartz pursued very different clinical courses: one died of rapidly progressive silicosis and the other developed hilar adenopathy and, later, early massive fibrosis. The man who died had a 30-year exposure estimated to have averaged <0.1mg/m3, leading to hilar node fibrosis and calcification, followed by a five year exposure to about 2mg/m3 which proved fatal. Estimates of exposure tallied with postmortem measurement of lung burden, suggesting retention of all dust deposited in the lungs over his final period of work. The younger man, working from the start of his apprenticeship alongside the older one, had a six year exposure to about 1.5mg/m3, which caused hilar node enlargement and subsequent calcification but minimal lung involvement. Exposures to relatively low concentrations of quartz may be capable of causing hilar node fibrosis, impairing the clearance of any quartz inhaled subsequently.

Use and misuse of the I.L.O. International Classification of Radiographs of Pneumoconiosis in occupational health
Du bon usage de la classification internationale du B.I.T. des radiographies de pneumoconioses en santé du travail [in French]
The I.L.O. International Classification of Radiographs of Pneumoconiosis provides a means for systematically recording the radiographic abnormalities in the chest provoked by the inhalation of dusts, in a simple and reproducible manner. After a brief description of the I.L.O. classification, its advantages and limitations are detailed so as to define the circumstances in which it should be used by occupational physicians.

Silica, compensated silicosis, and lung cancer in Western Australian goldminers
Silica has recently been reclassified as carcinogenic in humans based largely on the observed increase in rates of lung cancer in subjects with silicosis. This study aims to examine exposure-response relations between exposure to silica and subsequent silicosis and lung cancer in a cohort of goldminers. A total of 2,297 goldminers was examined in 1961, 1974 and 1975. Data were collected on respiratory symptoms, smoking habits and employment history. Subjects were followed up to the end of 1993. Survival analyses for lung cancer mortality and incidence of compensated silicosis were performed with age and year matched conditional logistic regression analyses. 89% of the cohort were traced to the end of 1993. 84% of the men had smoked at some time and 66% were current smokers. 1386 deaths occurred during the follow up period, 138 from lung cancer, and 631 subjects were compensated for silicosis. A strong effect of smoking on mortality from lung cancer and a smaller effect on the incidence of compensated silicosis was found. The incidence of silicosis was clearly related to exposure to silica and the onset of silicosis conferred a significant increase in risk for subsequent lung cancer, but there was no evidence that exposure to silica caused lung cancer in the absence of silicosis.

Association between exposure to crystalline silica and risk of sarcoidosis
The inhabitants of a district in which a diatomaceous earth plant is located formed the basis of this study. Cases of sarcoidosis were identified from hospital records according to certain clinical, radiological, and histological criteria. Referents were selected randomly from the population of the district. Information on exposure to crystalline silica, cristobalite, was obtained by record linkage of the cases and referents with a file which included all present and past workers at the diatomaceous earth plant and those who had worked at loading vessels with the product from the plant. Eight cases of sarcoidosis were found, six of which were in the exposed group. Of the 70 referents, 13 were exposed. The odds ratio was 13.2. The odds ratios were high and there were some indications of a dose-response relation which will hopefully encourage further studies. Topics: cristobalite; diatomaceous earth; silica; case-control study; dose-response relationship; long-term exposure; pseudosilicosis.

Relations between occupational exposure to coal mine dusts, erythrocyte catalase and Cu++/Zn++ superoxide dismutase activities, and the severity of coal workers' pneumoconiosis
Blood samples were obtained from miners without coal workers' pneumoconiosis (CWP) exposed to low dust concentrations for 4 or more years, or exposed to high dust concentrations for 14 or more years, and from retired miners with CWP. Estimated cumulative exposure to dust was strongly positively related to erythrocyte catalase activity and strongly negatively related to Cu++/Zn++ superoxide dismutase activity only in miners exposed to high dust concentrations for ≥14 years. Moreover, catalase activity was strongly related to the severity of CWP as determined by chest radiography. Results are in good agreement with the hypothesis that production of reactive oxygen species may be an important event in the exposure to coal mine dusts and the severity of CWP. Topics: coal mining; coalworkers pneumoconiosis; determination in blood; enzyme activity determination; enzyme activity; epidemiologic study; erythrocytes; respirable dust; superoxide dismutase.

Temporal trends in coal workers' pneumoconiosis prevalence - Validating the National Coal Study results
Evidence from four successive rounds of the U.S. National Study of Coal Workers' Pneumoconiosis (CWP) indicates diminishing prevalence of the disease from 1969 to 1988. However, methodological inconsistencies across surveys have raised concerns. A standardized methodological approach was used to confirm the reported downward trend. Re-evaluation of radiological findings showed that the prevalence of small rounded opacities declined from 12.7% in Round 1 to 3.9% in Round 4. These findings support the National Institute for Occupational Safety and Health's recommendations for a reduced exposure limit for coal dust of 1mg/m3 because the present standard does not sufficiently protect miners against adverse health effects over a working lifetime of exposures. Topics: chest radiography; coal dust; coal mining; coalworkers pneumoconiosis; epidemiologic study; frequency rates; limitation of exposure; opacities; radiological diagnosis; statistical trends; USA.

Respiratory diseases caused by inhalation of inorganic dust in the working environment
Patología respiratoria por inhalación de polvo inorgánico en el medio laboral [in Spanish]
Pneumoconioses, especially silicosis and asbestosis, are still frequent work-related diseases in spite of current preventive measures. Aggressive types of silicosis have been detected recently in such expanding industries as rock-processing. In addition to pneumoconioses, other adverse effects of mineral dust inhalation in the workplace have been detected in the last two decades. There is increasing evidence that occupational exposure to silica (and other mineral dust) could be a risk factor for bronchitis and chronic airflow limitation. The relationship between tuberculosis and silicosis is well known. Less clear is the possible relationship between tuberculosis and silica exposure. The carcinogenic effect of silica has been recently recognized. Topics: asbestosis; silica; coal dust; coalworkers pneumoconiosis; degree of disability; inorganic man-made fibres; literature survey; pneumoconiosis; respirable dust; respiratory diseases; siderosis; silicosis.

Exposure-response analysis of risk of respiratory disease associated with occupational exposure to chrysotile asbestos
Analysis of data from a cohort mortality study of textile factory workers confirmed findings from previous investigations of a strong exposure-response relation between exposure to chrysotile asbestos and mortality from both lung cancer and asbestosis. The excess lifetime risk for white men exposed for 45 years at the revised OSHA standard of 0.1 fibre/mL was predicted to be 5/1000 for lung cancer and 2/1000 for asbestosis. Topics: asbestos processing industry; asbestosis; chrysotile; asbestos; cohort study; dose-response relationship; hazard evaluation; lung cancer; mathematical models; mortality; prediction.

Mortality of Dutch coalminers in relation to pneumoconiosis, chronic obstructive pulmonary disease, and lung function
In a retrospective cohort study of 3,790 Dutch underground coal miners, excess mortalities from coal workers' pneumoconiosis (CWP) and chronic obstructive pulmonary diseases (COPD) were found. Diminished lung function at medical examination resulted in a significantly increased mortality from COPD, whereas normal lung function yielded expected mortalities from COPD. A positive correlation was also observed between diminished lung function and mortality from CWP. The risk of dying of COPD and CWP increased with decreasing body mass index at the time of medical examination. Topics: body weight; chronic bronchitis; coal dust; coal mining; coalworkers pneumoconiosis; cohort study; emphysema; lung diseases; mortality; Netherlands; pulmonary function.
