Mr. Hugh M. Jackson, Manager Industrial Health Program Jetma-Manvillo Corporation 22 East 40th Street Now York 16, New York .Do at Hugh: - . . . - At the time of our'/nnual Meeting you and I discussed the status of the ATI study, and 1 promisod to send you material which might be help ful. 1 realize that you will not be using it until January or .February, but thought I would send you what we turned, up immediately. We will continue to search and will sand you anything more that we find before the time of your meeting. In the Amo.rican Journal of Medicine for November 1953, Isaelbacher, Klaus, and Hardy have an article entitled, "Asbeetosis and Broncho genic Carcinoma". They roport one case buJ review the literature and they state that "about 10,000 worker* are probably engaged in potentially hazardous asbestos manufacturing operations in the United States. Most of the industry is engaged in asbestos textile manufacturing....." As early as 1936 Lanza estimated that about 12,000 individuals were employed in the chief asbestos plants in the Uaitod States, of whom 10,000 might be 'exposed. Hinsha-w and Garland In their book, "Discaooa of the Chest",'just off the press, state in part "exposure occurs in industrial plants whore asbestos products are fabri cated and among those who install. Insulating materials: the spinning and weaving of asbestos In combination with other textiles also results in exposure". -The Isselbacher article collocts 20 cases including their own, of which 10 apparently occurred in this.country. The occupations of these 1C cases were as follows: three weavers, two pipe insulators, one pipe coveror, one asbestos mill worker and sorter, and throe not known. The occupations of the other-10 (foreign) cases were as follows: spinner; rr.attrcss and opening departments; packer-stores department; carder, spinner, and weaver; preapinning-aescmbly room; machine adjuoter; bagger; pipe coveror; "asbestos worker"; and one who spent 18 years In an asbestos pl-.nl although the occupa tion Is not given. Mr. Hugh M. Jackson PLAINTIFF'S EXHIBIT 000l/ 00 1...... I I ; Dcimb<r 6, 1956 _ One conclusion of this article U that Asbestos Is associated with broncho* genic carcinoma in 13. of the cases cited in the literature. Doll, "Mortality from Lung Cancer in Asbestos Workers". British Journ. Ind. Med., April 1955, prosents data on 18 cases of lung cancer diag nosed at autopsy among 105 consecutive autopsies of workers in a large asbesto works. Fifteen of the 18 bad asbestosis end three did not. These individuals were not miners, of course, and their occupations included: nine weavers, three fiberixers, two disintegrators, one bag carrier, two spinners, and one maintenance man. In addition, we have found artlclas reporting at least seven other cases, mostly in the foreign literature and many of-which do not specify the occupation, JL. W. Smith, "Pneumoconiosis and Lung Cancer", Compensation Medicine, November 19^9# states that the American and .English figures cor* respond so closely that it becomes mors and more difficult to absolvo asbestos as a potential factor in the development of pulmonary cancer. Ke quotes a re* cent editorial in the JAMA as follows: "As the s vailable evidence.shows that the occurrence ol' cancer of the lung is related to pulmonary asbestosis *nA is not merely a possible sequela of exposure to asbestos dust.and states that claim a for compensation will become of increasing frequency due to the goaeral incroaee of carcinoma of tho lung. 1 hope that this material will be helpful to you in enlightening tho representivos of the toxtile industry. We will continue to send "ammunition" as we uncover it. With kindest personal regards. ' Sincerely yours. DCUilf Daniel C. Braun, M.D. Medical Director PLAINTIFF'S EXHIBIT IAM-OQOO'tlo
