The case of a 57-year-old man is reported, who worked as a plasma welder about 15 years. Chronic recurrent bronchitis was diagnosed 12 years after beginning of this work. The patient changed the place of his employment but the course of disease was uncommonly progressive. He died of right ventricular heart failure 10 years later. One year before death, the chronic obstructive pulmonary lesions were acknowledged as occupational disease. The post-mortem histological and chemical analysis of lung tissue yielded a mixed dust pneumoconiosis. These findings supported additionally the diagnosis of occupational disease.

The article presents medical examination and clinical data on 117 cases of silicosis, anthracosilicosis, electric welder's pneumoconiosis and dust bronchitis. Diagnostic and therapeutic procedures were performed with due account of generally accepted resort treatment recommendations. The data obtained served as a basis for determining the role of different symptoms and results of complimentary medical, including immunologic, techniques, as well as for objective assessment of the effectiveness of resort treatment of occupational diseases.

A thermographic study of the chest was of importance in the diagnosis and differential diagnosis of pneumoconiosis, chronic dust-induced bronchitis, unspecific pulmonary diseases. This could substitute traditional methods of examination. Results make it possible to recommend the method of thermography in the diagnosis of professional diseases as well as in periodic prophylactic screenings of coal miners.

The authors studied the influence of mountain climate (altitude: 2200 m) on the course of chronic dust-induced bronchitis, pneumoconiosis and vibration disease in 45 patients. It was found that a 1-month stay of patients with dust-induced bronchitis and pneumoconiosis in the mountains results in a positive clinical effect is accompanied by amelioration of the external respiratory function, positive changes of the hemodynamic values. Mountain climate treatment was ineffective in vibration disease.

The comment on the article by D. M. Zislin (Occupational Hygiene and Industrial Diseases, 1988, N 10) is presented. Proceeding from the author's own experience and literary data, the main statement of D. M. Zislin disputing the concept of dust pulmonary disease (DPD) in the modern occupational pulmonology, is analyzed. The common cause of pneumoconiosis and dust bronchitis has been identified as fibrogenic dust, allergic, carcinogenic and toxic characteristics of which can be only condition affecting the disease clinical character. The article shows that neither generality, nor the differences in the functional changes of external respiration can serve as a convincing argument for or against the existence of the concept of DPD. Modern histomorphologic studies give evidence that low-fibrogenic dusts practically simultaneously cause the onset of the pathologic process both in the interstitial tissue and in the bronchi, the outcome of the process being diffuse pneumosclerosis. The concept of DPD caused by low-fibrogenic dusts has been substantiated on the basis of common etiology and similar pathogenetic, clinical and functional manifestations.

A seven year old girl developed recurrent bronchitis since three month of life. Chronic wheezing remain between exacerbations. Pathological examination of her lung biopsy disclosed bronchiolar obstruction due to peribronchiolar fibroses. Storage of anthracoid material, compatible with pneumoconiosis in relation to impairment on mucociliary function, was present. This is an unusual picture in childhood.

The paper is concerned with the results of roentgenofunctional investigation of 293 miners, among them there were 63 patients with dust bronchitis and 230 patients with the main types of dust disease (anthracosis, silicosis and anthracosilicosis). Two-stage roentgenopneumopolygraphy (RPPG) with a chess grid and spiral pneumoroentgenography (SPRG) with a spiral grid were employed. Respiratory dysfunction in patients with pneumoconiosis depended on an x-ray and morphological type of fibrosis and stage of disease rather than on its type. The formation of zones of emphysematous inflation in the apical area, in the upper and middle regions of the lungs was revealed, however signs of basal emphysema were ++undetectable. Analysis of RPPG and SPRG findings has shown that unlike pneumoconiosis, dust bronchitis is characterized by earlier development of respiratory dysfunction of more noticeable type, particularly in early signs of disease.

The survival of 354 claimants for compensation for pulmonary asbestosis among former workers of the Wittenoom crocidolite mine and mill in Western Australia has been examined. There were 118 deaths up to December 1982. The median time between start of work and claim for compensation was 17 years. The standardised mortality ratio (SMR) for deaths from all causes was 2.65 (p less than 0.0001). The SMR for pneumoconiosis was 177.2 (p less than 0.0001), bronchitis and emphysema 2.6 (p = 0.04), tuberculosis 44.6 (p less than 0.0001), respiratory cancer (including five deaths from malignant pleural mesothelioma) 6.4 (p less than 0.0001), gastrointestinal cancer 1.6 (p = 0.22), all other cancers 1.6 (p = 0.17), heart disease 1.4 (p = 0.07), and all other causes 2.18 (p = 0.004). Plain chest radiographs taken within two years of claiming compensation were found for 238 subjects and were categorised independently by two observers according to the International Labour Organisation criteria without knowledge of exposure or compensation details. Profusion of radiographic opacities, age at claiming compensation, work in the Wittenoom mill, and degree of disability awarded by the pneumoconiosis medical board were significant predictors of survival, but total estimated exposure to asbestos was not. Radiographic profusion and degree of disability were, however, predictable by total exposure. The median survival from claim for compensation was 17 years in subjects with ILO category 1 pneumoconiosis, 12 years in category 2, and three years in category 3.

Content of lipid peroxides was increased in blood plasma of patients with dust-dependent diseases of lungs (fibrinogenous dust--pneumoconiosis, dust bronchitis; carcinogenous dust--dust bronchitis), whereas the tocopherol level was similar to normal values in pneumoconiosis and elevated in dust bronchitis. The increase in tocopherol content might be considered as a compensatory mechanism in response to augmented lipid peroxidation. At the same time, this compensation was not sufficiently effective, as a result of which the antioxidant activity was relatively decreased in blood plasma as well as the antioxidant control was impaired in tissues and accompanied by intensification of the free radical reactions.

A cross-sectional study to assess prevalence of respiratory abnormality was conducted among 107 South African foundry workers. The prevalence of pneumoconiosis was 10.3% overall, increasing to 38% for workers with more than 15 years of service. Dyspnea was present in 38% of workers, chronic simple bronchitis in 15.9%, and asthmatic symptoms in 27%. Pneumoconiosis was not associated with higher prevalence rates of other respiratory abnormalities. The high overall prevalence of respiratory symptoms might be explained by exposure to environmental pollutants other than dust.
