Middleton, Med. deport y trabajo 4788-4802, {Mar. 1952) English Section, The author presents a general review of silicosis, including etiology, pathogenesis, diagnosis, prognosis, and treatment. He then discusses the effects of mixed siliceous dusts and minerals, especially graphite, earthenware, and granite, Asbestosis, other fibrous silicate minerals, and non-fibrous silicate minerals are considered briefly. The effects of non-siliceous dusts, especially beryllium, and of vegetable dusts, are reviewed. 779 History of Lung Diseases of Coal Miners in Great Britain: Part II, 1875-1920, A. 'M*iklejohn. Brit. J.Ind. Med, 9, 93-98 (April 1952). The author continues the review of the history of miners' pneu moconiosis (see IHF Abst. 1136, Oct.' 1951). The principal developments in the period 1875-1920 were: the extension of interest in occupational .-liseases in other industries than mining; the development of workmen's compensation laws; and especially the gradual realization that free silica is an important factor in pneumoconiosis of miners. (80 Pneumoconiosis of Coal Miners in North East England with Special Reference to the Durham Coalfield. R. I. McCallum. Brit. J. Ind. Med. h 99-107 (April 1952). The extensive occurrence of pneumoconiosis late in the nineteenth century was reduced very greatly by improvements in ventilation at about the end c.1 the century. Mechanized mining has probably increased the true prevalence of pneumoconiosis, but diagnosis has also improved. Evidence from routine mass miniature radiography at eight Durham pits suggests that a minimum of 3 to 6% of men in those pits show well-markec! pneumoconiosis. Future developments in the coalfield will tend to intensify dust production and the risks of pneumoconiosis unless dust suppression methods are considerably extended. -- Cond, from Author's Summary
