Dear Manfredt
It appears that some thing in the nature of a teaepest has developed* whether in a teapot or perhaps in some large receptacle* over the somewhat inadequate but veil-Intended Information supplied to you by my friend and colleague, Doctor Robert Kotte, concerning come unfortunate results
which attended the use of Calcium DIb odium Versenate (5 cc
ampules supplied by Riker Laboratories)In the treatment of two infants suffering from lead poisoning. Under the circumstances it seems best for me to clear the atmosphere by a statement of the facto* so far as I have them* since ever? one involved in the matter seems to be touchy, suspioious or otherwise upset. It even appears that I am suspected of sabotage in the matter* and of being constitutionally opposed to the development and use of specific therapy in lead poisoning* although I find it difficult to believe that anyone has seriously entertained any such idea. At any rate, while I a m willing to do any required penance for m y s i n s , I do not accept quietly indirect queries concerning my medical and scientific attitudes, and therefor in the not unalloyed role of peacemaker* I am prepared to accept the intermediate position which invites any blows intended for myself or others.
The situation* with respect to the use of EUTA in the treatment of lead poisoning came about here seme months ago* when it was first suggested publicly that this agent might be useful. As is well known* I should think* I have had only a mild concern about the'treatment of the usual case of lead poisoning in the adult, although we have subjected a number of types of thcrapy to rather rigid investigation. Moreover* I have Inveighed* as vigorously as I know how* against the substitution of therapy for the preventive measures that are available and demonstrably effective* against industrial lead poisoning. On the other hand* I have been deeply concerned* for many years* over the serious problem of the development of adequate treatment for two types of lead poisoning which give rise to high incidence of fatalities* namely* lead encephalopathy in the infant and small child* and tetraethyl lead poisoning in the adult* which* if exposure is sufficient* is uniformly fatal. The former Is a public health

problem of rather serious proportions, which, at present, is not wholly preventable, and which, therefore, requires and will continue, until it is solved, to require effective treatment*
When it appeared that E D I A might be useful, I obtained all of the information I could get, together with a supply of the material, and conferred with the group here in Cincinnati with whom I have collaborated for many years in the diagnosis of cases and in the study of the problem. I strongly reooumended the use of the px'oduct in the treatment of selected cases of grave illness, and found complete agreement that the highly unfavorable prognosis justified the trial of the preparation. A means of following the cases, to determine the extent of the
clinical benefits and to observe tb* effects upon .the lead metabolism, was agreed upon, well before the time of year when such cases can be expected to reach their peak incidence, (Wo
had somewhat in excess of twenty cases in 1951, with a mortality
of about one third, and we are quite certain of seeing several serious cases, some of which are destined to be fatal, during the summer months of any year.) Meanwhile you (Bowditch) and Doctor Wheatley had been in more or less continuing communica tion with Doctor Kotte on the matter of lead poisoning as veil as other types of illness among children, and ve complied with your request to cake such suggestions as ve could for a form of report and an outline of procedures Indicated for demonstrating the results of therapy. Our own procedure differed somewhat from that which was regarded as essential and that which could be carried out in certain other places, with particular reference
to the analytical regimen. In this ve followed our own counsel, since I have not been favorably impressed by the critique, or I should say, the lack of critique, on either the clinical or metabolic effects of tho use of remedial agents in recent years in lead poisoning, because of the a lmost complete disregard of the known facts concerning the metabolism of lead in health ahcTlXlaease and the^reliability of the methods required to establish the facts in the individual case, on the part of most of those who have; undertaken such observations. Such methods were not available in the nineteen twenties, and there was no serviceable information on the subject until after the late thirties. There are such methods now and some data, but neither the methods nor the data have been taken seriously by sore than a very few people. Consequently, I may be forgiven, perhaps, If
I considered that it would be necessary for us to answer questions on tho metabolic aspects of the matter for ourselves. :
ho suitable cases ,of lead encephalopathy among children were available for .treatment until the late summer of this year, but two such cases appeared then, and treatment was initiated with EDI'A in the Cincinnati General Hospital (I misinformed Lanza in an earlier letter, by saying that these were in the Children's Hospital). I was away at the time,but Doctor Kotte felt that it was vise to infoxm you (Bowditch) of what had occurred. The cases were not his own, and he had no direct or delegated

authority to obtain or to give out any detailed Information,
especially In the absence of the Chief of the Pedlatrlo
Service of the Hospital* He spoke,therefore, In general terms, feeling that It vas best that every one concerned should knov that caution should be exercised In the use of the cate rial in the case of infante. It vas this cautious warning of Dr. Kotte that precipitated the present situation. The correspondence vlth Dr. Kotte, which I regard as based on some lnpatience and misunderstanding ,haa troubled and offended him, as will be seen from his replies to the correspondence. His reaction vould seem to me also to have resulted from some degree of misunderstanding, but he Is a sensitive and honorable man, if perhaps somewhat Inarticulate In spots, who would deeply resent any implication that he has been devious or anything less than completely straightforward in his dealings,with his professional colleagues.
The essential facts about the two cases, vhlch Will require care ful sifting by those responsible for the Service, as reported briefly to mo, are as follows * Both children were dangerously ill,'were hypertensive at the time the specific treatment vas attempted, and both reacted badly to the test doss with further arterial and intracranial hypertension. The reaction vas prompt and alarming, and while It may not have been due to the effects of the drug. It appeared to be. One of the children died In such unfortunate time relationship (l am not certain of the time interval) to the attempted therapy as to convince the resident staff that they do not wish to employ the'drug in similar cases in the future. Thie fact also conditioned their reaction to giving out Information that might bring serious criticism .upon themselves and the Hospital, until ouoh a time as the Chief of the Service had assumed responsibility for further action.
I have taken up the matter of furnishing the .group vlth appropriate
information on the results of the treatment of .the two children,
and I ae assured that it will be forthcoming shortly. The Chief
of Service has been away until recently. He has been heavily
engaged in gathering up the loose ends of his work, and vas not
aware of the significance of the matter, at Issue .until I explained
It to him yesterday. (I have been out of town much of late,
myself, and was too busy to go into it sooner.) In due course,
therefore, the matter will be aired fully and reported in such
manner as those responsible cay determine. Meanwhile, one must

to avoid obscuring the possible usefulness of a remedial agent.
More favorable news can be reported vlth referenc to an experience wi/th:EDTA in the, therapy of tetraethyl lead poisoning. A recent episode in Panama took one of m y Internist associates to Panama City, to assist in the treatment of seme seventeen men, who had been poisoned because of failure to carry out the prescribed precautions for cleaning tanka in vhlch leaded gasoline had been
stored. Two of these men died before he arrived. Three others

That there vere no further fatalities may not he attributed to the beneficial effects of the use of BIX.'A* a supply of vhlch vos taken along* and further supplies obtained from Dr. Boole (whose accidental death* some days later has shocked all of ua). However, the drug was veil tolerated by these patients* and observations vere made as veil as they could be under the circumstances to determine the metabolic effects of the use of the drug' in certain of these cases.

It does not follov* of course* that these facts will have any important bearing on the problem of lead poisoning from inorganic poisoning, but they will have some significance, I hope* in relation to TEL poisoning.

Our experience* although as yet inadequately reported, fully Justifies the position taken by the group ihat this preparation should not be distributed for general use, until such a time as adequate evidence can be obtained concerning its possible benefits and dangers. The incident and the hubbub about it also demonstrate clearly that the applica bility of a proposed new remedy needs to be examined in an attitude of unhurried objectivity* rather than in an aura of enthusiasm based on theroretioal considerations however exciting they may be*
I have given this letter as vide circulation as secncd ne-cc?uory at tills time. In view of the fact that I have gone somevhat outside my own professional province in reporting incomplete end inadequate information on patients who vere not under my care* I must ask that this information be handled with appropriate professional discretion until the facts halve been released by the responsible physicians.
