RAYON DEPARTMENT RAYON DIVISION "A I R MAI L" Old Hickory, Tennessee February 2k, I9V7 Dr. Robert A. Kehoe University of Cincinnati Kettering Laboratory College of Medicine Eden Avenue Cincinnati 19, Ohio Dear Dr. Kehoe: ^^^receLved your letter of February 21 regarding the case off^HHIHBB I appreciate very much your comments and would like to have your laboratory endeavor to determine this man's status. If you will furnish us with the necessary con tainers and instructions for their use and what other informa tion may be pertinent to their proper handling, we will return them as promptly as we can. In reading your letter, I get the impression that the subjective symptoms are practically valueless in the early diag nosis of lead poisoning. I am enclosing copy of a form we use in the examination of our leadburners and their helpers each month. It occurs to me that it is possible we are consuming a great deal of time and effort and getting very little practical information. Would it be better, in your opinion, to establish a different period of time to examine these men (including painters) and at that time possibly,for the sake of discussion, at two or three-month intervals run a blood and urine determina tion for lead? In this way, we would establish an average for the entire group and thus be in a better position to recognize the appearance of abnormal amounts should they occur. At the present time I do not believe it will be worth while to check the accuracy of our own laboratory until our im mediate problem is solved and we establish the best possible method of follow-ups on our people exposed to lead. I would appreciate your outlining what you would con sider an adequate routine that we may follow. We will, of course, be responsible for all normal fees. Very truly yours, /W. r. MILLER, M.D. MEDICAL SUPERVISOR v
