Oyanguren and E. Bartholin Rev. mcd de Chile 71 464 May 1943 The diagnosis of silicosis has been confirmed by demonstration of silica in the sputum and blood of 40 individuals Silica which is conveyed to the lungs by inhalation is taken up in greater part by the lymphatics and the remainder is expectorated Silica interferes with the lymphatic circulation producing a fibrous proliferation which eventually results in the inclusion of the particles themselves But before this occurs the silice which is inhaled passes through the blood and may be excreted in the urine Silica may normally be found in the blood but if the quantity is less than 8 mg percent as determined by the colorimetric method it is believed to be of no clinical significance Quantities from 12 to 20 mg percent are expressed as 1 plus from 20 to 50 mg percent 2 plus and above 50 mg percent 3 plus Positive chemical reactions for silica in the sputum may be obtained in all cases of silicosis The positive reactions in the blood correspond to the amounts of silica contained in the sputum and positive chemical reactions are found only in those individuals who have been exposed to bearing dust The specific chemical reaction used is that described by Oberhauser and depends on the reaction obtained with nitromolybdonate of ammonia This may be used equally on the blood and sputum and is a more certain test than the spectrographic methods ~- Am Rev.

They have no relation to asbestos of the lungs One characteristic is that they appear and foel as if a foreign body were present none is ever found It is probable however that one is present in the very early stages 59 Asbestosis and Pulmonary Carcinoma H.W. Wedler Deut med Wochschr 69 575576 Aug. 6 1943 German The author has collected the published autopsy records on asbestosis from various countries and finds that there have been 14 instances of malignant disease of the lungs and pleura in 92 mortem examinations 16 percent This is in excess of the proportion of lung carcinomata in autopsies generally 2-6 percent Carcinoma as a complication of asbestosis occurred most frequently in males between 35 and 41 and was generally in the part of the lung most affected with asbestosis Development of the lesion was slow but corresponded with the length and intensity of the exposure 12-42 years There was often a long interval between the cessation of exposure and the development of the cancer which in the author's view must now be regarded as an occupational cancer -- Bull Hyg Skin Diseases and Burns N.
