P. S. Dr. Lanahan , I presume we are to send our reports directly to Doctor Parns- ' worth, rather than to you, hut it seems wise to send you a copy of this letter. If you want to instruct us differently, do not hesitate to do so. R.A.K. October 26, 1948 e\> o. Ui Dr. J. J. Farnsworth, The Electric Storage 129 Belmont Blvd., Kansas City 1, Mo. Co., Dear Doctor Farnsworth* I send you herewith the analytical results on the urine and blood of your patient, -The'report is self explanatory, X believe. .- In connection with the interpretation of analytical results we very commonly neeo information beyond that contained in your letter. . Ihat this was not true in this instance was due to the fact that the results were quite high and, therefore, carried the implication of danger in themselves, ifowever, even in this instance it would be advisable for us to have other information, and under certain condi tions no sensible interpretation can be made without additional facts, lour letters to us -thotiid' carry at least the following items of information: ' .' '' A, 1. Ihe nature of the man's occupation within the plant; (I have not seen your plant, but I am generally familiar with the ope* tions, of battery plants, and will knew something oi the relative hazards of\ the individual occupations .j 2. The duration of the man's employment In this job, and his total length of employment in the plant; This information should show whether the employment was continuous or intermittent, so that we can interpret the all-over picture man's occupational lead exposure in terms of its durtionyCOMiar as possible its severity as well. Lead excretion is a function of lead absorption over a period of time, and both severity and duration are of the utmost importance in the understanding of the excretory data. 3. ,'It is necessary to know whether the individual worked under conditions of occupational exposure up to the time the samples were obtained. If this is not tne case, the interval of time between the last day of exposure and the day on which the samples were obtained should be clearly Indicated. 4. The stippling is not very important to us, since the degree of stippling is not related to the severity of the lead exposure. How ever, we are glad to have this information. It is much more important however, that, we should know all of the features of the clinical condition that presentiltheiEseives. This can be done briefly, but ve should have this information in order to be of maximum help to you. . Very truly yours, RAK ef Robert . ehoe , M. t>. Came ; Material: Submitted Crine and Blood %.
