The author quot from me literature and presents the histories of seven patients observed by himself which illustrate the three stages of the disease. He aiso comments on the incidence, etiology, pathologic anatomy, and diagnosis. Generally, th disease develops only after the worker has worked with cotton for at least five years. A constricted, tight feeling m the chest is usually the first mani festation, and since this symptom is often severest on Moncays, me term "Monday fever" orMonday cough" has been applied to it. Patients with the aavaneed form of byssmosis may die of decompensation of the right side of iiv heart. Prophylaxis is of primary importance ana should involve giving atten tion to the selection of worxers ana to dust control m cotton mills. - -- .-ircr.. .tid. .-.vg. id Oww. ...cd. Studies on Cotton Dust in Relation to Byssmosis. Part III. Comsarison of Cotton Dust ana House Dust ev Chemical ana Skin Tests. A. Cayton, G. Furness, Q. S. Jacxson, ana H. o. Maitiana. Brit. J. Ir.d. Med. 9, 303-308 (Oct. 1952). An extract of cotton oust nas been comparea chemically and by sum tests with extracts of house dust. 3oth contained a poiysaccr.aride associaics wuh a polypeptide grouping of amino-acids giving none of the usuai coior reactions for proteins. Quantitative and chromatograpnic tests reveaied a similarity m the sugars ana ammo-acids detected. Both extracts produces the eariy type of skin reaction. Cotton dust generally proauccd also a late skin reaction, whereas the house dust did not. The two extracts, therefore, were not identical. Polysaccharide-polypeptide compounds were probably responsible for tr.e early sxm reaction.

The extent of tuberculosis is .* pparently typical of such areas m the country. About 30% of the miners ana e* 'miners had some roentgenological signs of pneumoconiosis; 15% had progressive massive fibrosis. All but two patients with infectious tuberculosis were given r.o_pitai treatment. The number of infectious cases has been reduced by about 60-33 and the patients are ail being closely supervised by a health visitor.

Symptomatology, diagnosis, and x-ray findings m the different :is of asbestosis are described. Special mention :s made of the association -icestosis with carcinoma, wnich is much more frequent than mat of sili.i. Post-mortem reports from the literature indicate that m 309 cases . -soestosis there were 44 lung carcinomas (14.1%), whereas in 2,204 eases -.cosh only 12 carcinomas wer- found (1.4%). The experience of the -. .-ciation of tuberculosis and asbestosis varies greatly in different countries, -.ish investigators have recorded a high rate of tuberculous infection m -stos workers, hut i: is * rare complicat^n m America and the rate is low Germany. The macrocepic and microscopic appearances ox the lungs are tcribed. and the nature and significance of asbestosis bodies are discussed " m extensive reference list dealing with that controversial subject is given. -- Cond. from Bull.
