May IS* 1339 Dr, J, Edward Hershberger 1901 S&lm Avenue Dayton* Ohio Dear Doctor Hershberger* In reply to your letter of May 11th* I have seen no reason for believing that there is any Interaction between bensol poisoning and lead poisoning, I can conceive of a case in which the*combination of these two toxic substances at the same time would produce more disastrous results than either alone* but I have never seen such a case. As to the possible relationship between a case of lead poisoning at age twenty and a case of benzol poisoning at age fifty-two* I can not conceive of any connection whatsoever. One who has been poisoned with 'cad at age twenty* will not have any quantity of lead in hia body greater than the- no real level at age fifty-two. It 1 quite beyond any doubt that lead do not remain stored in the body for any such period of time, and *here is* so far as I can sec* no way by which & subsequent benzol poisoning oould be influenced by a previous lead poison ing with such an Interval of time intervening. Obviously certain sequelae of lead poisoning say persist for an indefinite period of time. In my experience these sequelae are almost exclusively nervous or neuro-maseular in character* that is paralysis* paresis, or cerebral disturbance, I do not see how such sequelae would be influenced by a subsequent episode of benzol intoxication. If I oould be of any assistance to you in answering certain specific question with relation to the diagnosia* I should be pleased to do so. Cordially yours* RAK* is Robert""X. Kiehoe* M.S, *7
