E. Concina and O. Orlandi. R ass. m ed. ind. 20, 424-426 (N ov.-D ec. 1951) Italian. The im portance of the existence of bronchial lesions in silico sis has been underestim ated. Bronchoscopy allows direct observations of changes in the tracheal and bronchial mucous m em brane, deviations in the trach ea and m ain bronchi, and m odifications in the o rific es of the lobes and segm ents. Lavage, aspiration of the bronchial section, and endo bronchial adm inistration of adrenaline and antibiotics majN>e conducted during the p ro cess. Inflammation of the mucous m em branes and other changes characteristic of silicosis are disclosed by this method. Findings in 25 p atien ts a r e re p o rte d . -- Cond. from Bull.

The au th o r used the e le c tro c a rd io g ra p h to exam ine 11 c a se s of anthraco-silicosis with clinical signs'of loss of com pensation of the right ventricle, and 200 cases of an th raco -silico sis, com pensated for invalidity but s till am bulant, who w ere doubly c la ssified according to the extent of fibrosis present and according to the amount of em physem a. The findings are presented in somewhat cryptic sym bolism . They a re held to justify the claim that the electrocardiograph m ay be of considerable value in establishing early strain on the right side of the heart. -- Bull. Hyg. Data for statistical proof of any association of asbestosis with pulmonary carcinom a are hard to collect, but three investigators have found carcinom a in 7 .5 to 14.8% of c a se s of a sb e sto sis. A case is rep o rted in which a w orker had been exposed to asb esto s for 6 y e ars and had refused to w ear a re s p ira to r. He cam e under notice with w eakness and a p e rs iste n t cough. Clumps of malignant cells w ere seen in the bone m arrow , and x -ra y showed generalized large d iscrete oval shadows indicative of pulmonary m tasta s s. A fter death, m odules varying to 4 cm . in diam eter w ere found scattered throughout both lungs, with in te rstitial fib ro sis. L arge a re a s of necrosis existed throughout the lungs, and typical asbestos bodies w ere seen inside and outside the tum or a re a s . M tastass w ere found in the kidneys, brain, and liver. The ^Q pn.is suggested that the silicate in asbestbs m u lt itself be directly c a r c ih ^ ih ic .

The Foundation's staff includes physicians, chemists, engineers, industrial hygienists and medical technicians-- all specialists in health problems arising in manufacturing and raining. Through affiliation with I n d u s t r ia l H y g ie n e F o u n d a t io n , companies are entitled to the services of these specialists, plus the technical facilities of Mellon Institute, the Foundation's headquarters. FOUNDATION ACTIVITIES The activities of I-H-F fall into three major categories: (1) To rive direct professional assistance to member companies i in the study and solution of industrial health problems. (2) To assist companies in the development of health and medical j programs as essential parts of industrial organizations. (3) To contribute to the scientific advancement of industrial ; medicine and hygiene, through research, surveys and allied activities. The broad scope of questions and problems that come to the Foundation for consideration is snown by the follow ing tabulation o f activities, classified under eight major headings: (1) medical, (2) chemistry, toxicology and in d u stry hygiene, (3) engineering, (4) air pollution, (5) noise, (6) research, (7) legal, and (8) general advancement of industrial health. j (1) Medical (a) Gencral information and advice on o ^ a n h ^ tio a ^ u i4 ^ u n < arriTanriym, plans lor physical layoutt, perionnel needs and ration on specific industrial medical problems and ex- (2) Chemistry, Toxicology and Industrial Hygiene (a) Industrial hygiene field studies are conducted--appraisals of nature and magnitude of hazardous exposures ana effect iveness of control measures. These may be on a plant basis or on an industry-wide scale. (b) Information on toxicity of chemical and physical agents, and on hazards of particular processes; preparation of bibliog raphies, literature searches, and securing of information from other sources, as, for example, companies having related problems. (c) Information and advice on sampling and analytical proce dures, choice and availability of equipment. (d) Preliminary training of industrial hygiene personnel in lab oratory procedures, sources of information, organization of laboratory, record keeping, etc. (e) Studies and development of new sampling and analytical methods and techniques.
