industrial Hygiene Digest - 29 September, 1952 )q07 Findings of Bronchoscopy in Silicosis and Silico-Tuberculosis. E. Coneina and O. Orlandi. Rass. med. ind. 20, 424-426 (Nov.-Dec. 1951) Italian. The importance of the existence of bronchial lesions in silicosis has been underestimated. Bronchoscopy allows direct observations of changes in the tracheal and bronchial mucous membrane, deviations in the trachea and main bronchi, and modifications in the orifices of the lobes and segments. Lavage, aspiration of the bronchial section, and endo bronchial administration of adrenaline and antibiotics may be conducted during the process. Inflammation of the mucous membranes and other changes characteristic of silicosis are disclosed by this method. Findings in 25 patients are reported. -- Cond. from Bull. Hyg. 1008 The Value of the Electrocardiograph for Examining Anthraco-Sillcotlca. F. Lavenne. Institut d'Hygiene des Mines, Hasseit, Belgium, Communication No. 90, 5pp. (1951). French. The author used the electrocardiograph to examine 11 eases of anthraco-silicosis with clinical signs of loss of compensation of the right ventricle, and 200 cases of anthraco-silicosis, compensated for invalidity but still ambulant, who were doubly classified according to the extent of fibrosis present and according to the amount of emphysema. The findings are presented in somewhat cryptic symbolism. They fire held to justify the claim that the electrocardiograph may be of considerable value in establishing early strain on the right side of the heart. -- Bull. Hyg. 1009 Asbestosis Associated with Bronchiogenic Carcinoma. R. Stoll, R. Bass, ,and A. A. Angrist. Arch. Intern. Med. 88, 831-834 (Dec. 1951) German.' Data for statistical proof of any association of asbestosis with pulmonary carcinoma are hard to collect, but three Investigators have found carcinoma in 7.5 to 14.8% of cases of asbestosis. A ease is reported in which a worker had been exposed to asbestos for 6 years and had refused to wear a respirator. He came under notice with weakness and a persistent cough. Clumps of malignant cells were seen in the bone marrow, and x-ray showed generalised large discrete oval shadows indicative of pulmonary metastases. After death, modules varying to 4 cm. in diameter were found scattered throughout both lungs, with interstitial fibrosis. Large areas of necrosis existed throughout the lungs, and typical asbestos bodies were seen inside and outside the tumor areas. Metastases were found in the kidneys, brain, and liver. The opinion is suggested that the silicate in asbestos must itself be directly carcinogenic. It establishes an additional reason for pre ventive measures in the use of asbestos. - Cond. from Bull.
