Review
Pneumoconiosis refers to a spectrum of pulmonary diseases caused by inhalation of mineral dust, usually as the result of certain occupations. The main pathological features include chronic pulmonary inflammation and progressive pulmonary fibrosis, which can eventually lead to death caused by respiratory and/or heart failure. Pneumoconiosis is widespread globally, seriously threatening global public health. Its high incidence and mortality lie in improper occupational protection, and in the lack of early diagnostic methods and effective treatments. This article reviews the epidemiology, safeguard procedures, diagnosis, and treatment of pneumoconiosis, and summarizes recent research advances and future research prospects.

Review
Occupational lung diseases are caused or made worse by exposure to harmful substances in the work-place. "Pneumoconiosis" is the term used for the diseases associated with inhalation of mineral dusts. While many of these broad-spectrum substances may be encountered in the general environment, many occur in the work-place for greater amounts as a result of industrial processes; therefore, a range of lung reactions may occur as a result of work-place exposure. Physicians in metropolitan cities are likely to encounter pneumoconiosis for two reasons: (i) patients coming to seek medical help from geographic areas where pneumoconiosis is common, and (ii) pneumoconiosis caused by unregulated small-scale industries that are housed in poorly ventilated sheds within the city. A sound knowledge about the various pneumoconioses and a high index of suspicion are necessary in order to make a diagnosis. Identifying the disease is important not only for treatment of the individual case but also to recognise and prevent similar disease in co-workers.

Immunological investigations of 37 patients with bagassosis, 92 unaffected bagasse workers, and 150 non-exposed controls showed that precipitins against extracts of bagasse could be demonstrated just as frequently in the unaffected and the non-exposed as in the affected. However, there was a general tendency for the precipitin levels of patients with bagassosis to fall slightly with increasing time after recovery from the clinical episode. The presence of the precipitins so far demonstrated in the sera of bagasse workers therefore appears to be of no clinical significance. Inhalation tests with an extract of bagasse, in a group of 16 patients who had had bagassosis, produced late, systemic reactions in 15 similar to those described in farmer's lung and bird fancier's lung, so supporting the hypothesis that a similar type of hypersensitivity is the cause of bagassosis. Inhalation of extracts of also produced typical, late reactions in 12 out of 15 subjects, whereas extracts of failed to produce reactions in any of 16 subjects. The specific reactions to inhalation tests with were typical of a precipitin-mediated type of hypersensitivity reaction and support the view that this actinomycete may be important in the aetiology of bagassosis.

The only workers presently exposed to bagasse dust in Japan are the employees of sugar refineries and lacquerware factories. A follow up study of six former cases of bagassosis from among the retired employees of a paper board factory, closed since 1973, showed that none of the subjects still had bagassosis. Examinations of 70 employees of a sugar refinery for allergic reactions also showed no case of bagassosis. Seven cases with suspicious shadows of bagassosis on chest radiographs and four cases with positive serum precipitin to stored bagasse were, however, found among those 70 subjects. The results show the disappearance of a past episode of bagassosis and the possibility of a new occurrence of bagassosis among the employees of sugar refineries and lacquerware factories in the near future in Japan.
