The importance of personal and occu pational history is emphasised.. The factors to be considered when deciding whether a man should be taken from his job arc discussed. 604 The Clinical Picture and Pathology of Asbcsrosis. W. Behrens, Jr. Z. UnfaLimed. u. Beruikrankh. 45. 129-140 (June 15, 1952); 179-139 (Sept. 15, 1952). German. This paper presents an extensive review of literature on asbestosis including distribution and types of asbestos, its mining, treatment, and use, dust hazards, and effects of length of exposure of the dust in different con centration. Symptomatology, diagnosis, and x-ray findings in the different "* stages of asbestosis are described. Special mention i3 made of the-association of asbestosis with carcinorria, which is much more frequent than that of sili cosis. Post-mortem reports from the literature indicate that in 309 .cases of asbestosis there were 44 lung carcinomas (14.2%), whereas in 2,204 cases of silicosis only 32 carcinomas were found (J.4%). The experience of the association of tuberculosis and asbestosis varies greatly in different countries. English investigators have recorded a high rate of tuberculous infection in asbestos workers, but it is a rare complication in America and the rate is low in Germany. The macroscopic and microscopic appearances of the lungs are described, and the nature and significance of asbestosis bodies are discussed and an extensive reference list dealing with that controversial subject is given. -- Cond. from Bull.
