July 5, 19^0 Mr. Mathias H. Heck 815 U. B. Building Dayton, Ohio Dear Mr. Hock: As the result of our interview on the afternoon of July 1st, I ax^sendinp: herewith a statement on the case in so far as the factsag^nown to me .^^^oT^cnow I have not seen Mr. IRfor several years and I have no direct knowledg^ofhis present condition. However the results of Dr. Fischbein's examination are quite adequate to establish the facts in that regard and therefore I have no hesitation in expressing my opinion, I trust that this statement will cover your requirements. Very truly yours. RAK:is Robert A. Kehoe, M.D 0020850 Claim No. O.D. 2129 Claimant Harold Sibole Age: I4J4. Date: July 5, 19^0 The facts concerning the original illness of and the relationship of his present condition to that illness are not entirely clear, end it appears that a statement from me might be beneficial in clarifying certain aspects of these matters, in as much as I, as plant physician, was responsible for the medical care of Mr. during his employment and in the early phase of his illness Sr. was employed by Ethyl Gasoline Corporation in its Dayton, Ohio,plant for blending Ethyl Fluid, in December of 1;/2I4. At this time the hazards in the handling of Ethyl Fluid had been explored in at least a preliminary practical fashion and safeguards had been devised for the purpose of enabling the workmen to avoid serious lead exposure. As a consequence it was not anticipated that cases of lead poisoning would develop, and in fact nothing more serious than minor or doubtful symptoms were noted in workmen during this period. Mr. Sibole had not been em ployed during a previous period when conditions in the plant had been inadequately controlled and there was no reason to suspect that he had ever been seriously exposed to load. Accordingly when he became ill and was seen by me on March 11^ 1925 with what appeared to me to be a typical case of influenza, which was then occurring with somewhat les3 than epidemic proportions, I sent him home (after an examination) to be cared for by his own physician, with no apprehension as to any toxic manifestations of lead. 0020851 N 24431.01 2 The report of a private physician indicated that the case of following the normal pattern, until Saturday, March 28th, at which time I was informed that he was delirious. I saw him in the afternoon and from the clinical picture at that time, and from my belief that his lead exposure had not been severe enough to produce lead encephalopathy, I concluded that we were dealing with a post-influenzal encephalitis. (In this connection other physicians, who since have discarded completely the possible relationship of influenza to^^^jjjjjj^cerebral condition, have not had the benefit of seeing the onset and character of his illness, nor do they know anything about the plant conditions under which worked. They make the unwarranted assumption that had a serious and obviously dangerous lead exposure, and on that basis arrive at a conclusion by much too simple processes of reasoning.) Despite my tentative opinion as to the nature of the case, I considered it wise to hospitalize Mr. to keep him tinder observation, and to Instigate treatment on the possibility that his condition was due to the absorption of tetraethyl lead. Facilities for making a prompt differential diagnosis were not available then as now, and, in my opinion, treatment was Indicated on the theory that If lead were a factor^ failure to treat the patient might result fatally. Accordingly Mrwas put under treatment in a private hospital, where he remained until he became so noisy and uncontrollable as to necessitate his transfer to the Dayton State Hospital, at which time he went out of my care. Fearing that his conditions would not be understood and that medical treatment might not be carried out, I followed him to the hospital and conferred K 0020352 -5- with the house-staff, acquainting them with my point of view and suggesting that the patient he treated as though he were admittedly suffering from tetraethyl lead intoxication. It was in this manner that the visiting staff of the hospital came by the admission diagnosis of tetraethyl lead poisoning, regard less of such confirmation as their subsequent observations may have provided. The patient's subsequent course la a matter of record, and requires no additional information from me as to tho facts. The experience of the past fifteen years, with respect to the potential dangers in the handling of tetraethyl lead, as well as the course and sequellae of tetraethyl lead poisoning, throws light on this case, and should be of value in the determination of the present status of By roason of such experience, it now seems much more assured than it was at the time, that Mr. acute illness was the result of absorption of tetraethyl lead and certain of its decomposition products. Several factors contribute to that opinion, which, unfortunately, is not subject to proof. First, despite the fact that no other person in the group among which Mr. worked became ill as the result of lead absorption, {all other cases reported from Dayton occurred in an earlier period when the conditions were admittedly hazardous), one knows that certain opportunities for exposure existed at that time potentially which would be considered^dangerous now. Therefore Mr. have had greater exposure than I believed at the time of his initial illness. Second, the time of the onset of the cerebral symptoms in relation to the cessation of exposure, and the development of the HE 0020853 symptoms, which then were believed to be atypical, have since been found to be characteristic of a certain proportion of acute cases. Third, two cases of a schizophrenic type of response to tetraethyl lead intoxication, in association with previous histories of behavior tendencies in this direction, have demonstrated the ability of this intoxication to intensify such mental patterns, at least temporarily. Recovery occurred in both of these cases, and indeed it may be said that no permanent sequellae have ever been seen in relation to tetraethyl lead intoxication. On the other hand J!r. Sibole had definite stigmata of mental instability during my acquaintance with him, and the development of a definite psychosi might be regarded as the sequel of an acute tetraethyl load intoxi cation, emphasized by the shock of commitment and treatment in an institution for the insane as well as subsequent nervous trauma from family, friends and acquaintances. This might be regarded as compensation neurosis but for the fact that compensation was dis continued some time ago, and the further fact that his present mental condition of mental deterioration, according to the results of the recent (May 27> 19^0) examination of Dr. 3. C. FIschbein, would appear to be too serious to fit in that category. There is, of course, some doubt as to the specific effects of tetraethyl lead absorption in this case, and it could be argued that the present merit cl status of Mr. Sibole would have developed on some other stimulus, or perhaps without any special stimulus. Be this as it may, his present condition developed immediately after KE 0020854 -5" his acute Illness, and has existed continuously since, and therefore it would 3eem somewhat arbitrary to separate the one from the other. It is my opinion, based on the considerations above, together with the results of Dr. Fischbein*s examination as referred to, that Mr. jjdU^disabili ty is permanent and that It may properly be regarded as the result of the acute intoxication from which he suffered In 1925, not In the sense that that intoxication produced organic disease of the brain with permanent damage, but rather that the intoxication was the stimulus which brought out an abnormal mental state and contributed to its establishment as a fixed be havior pattern. 0020855 CLINICAL HISTORY OF mH|^Phas been an employe of the Ethyl Oasoline Cor poration sinc^December, 1924. History taken at that time dis closed no significant previous Illness. His previous employment showed no indications of any absorption of lead or of any other toxic substances. Physical examination showed only the following findings: Tonsils are large, rough and anterior pillars injected. Small amount of liquid puss could be expressed from either tonsil. Teeth showed a moderate pyorrhea with some retraction but no deep purulent pockets. Chest rather poorly developed. No abnormalities could be found In either the lungs or the heart. Color - sallow. There were no abnormalities found on examination of the blood and urine. During the time of his employment no significant illness occurred. In February he developed a common cold which persisted for about two weeks leaving him in a somewhat subnormal state. At this time his temperature and blood pressure were subnormal in the early morning hours but no other signs of illness were apparent. He was off from work for several days and returned in apparently normal state. On March 17th he reported with a very severe headache, cough, sore throat, and a temperature of 99-4/5. He complained of great muscular sore ness and intense weakness. He was sent home and from that time on was under the care of other physicians. His condition was reported as improving until Saturday, March 28th when it.was reported to me that he was delirious. when seen by me Saturday afternoon his condition was as follows: He was lying in bed apparently in a stupor with eyes staring. He was unable to recognize anyone but his wife, talked somewhat irrationally at times, and refused all medication and food. His c on-- dition at this time resembled rather strikingly a post influensal encephalitis but the description of his previous behavior by his family and the physician together with afebrile character of his condition suggested tetraethyl lead intoxication. His family stated that he had been delirious, apparently fearful, having had very disturbing dreams and otherwise running amuck, `^he family physician had felt it necessary the night before- to quiet him and had adminis tered morphine, 1/2 grain in one dose. This morphine and other hypnotics had failed entirely to quiet him at the time but it would appear that his later stuporous condition was in part the effect of the morphine. With presumable diagnosis of a secondary lead intoxication superimposed upon a convalescent acute infection, treatment was instituted for the clearing up of the mental state and the elimi nation of lead. Inasmuch as no medication could be given orally, a solution of sodium carbonate and sodium chloride (known as Fischers Solution) was instilled per rectum. This was retained fairly well. About two hours later the patient became rational, recognized me and K'E' 0020856 N 24431.02 cC 8- - and the members of his family and agreed to do anything that was required of him. Food was given in the form of fruit juices heavily sweetened with dextrose and arrangements were made to move the patient to a hospital for treatment. He was therefore admitted into the private hospital of Doctor Hatcher at 28 Monument Avenue. He spent Saturday night quietly but slept only about two hours. On Sunday morning he awakened in a confused mental state and his con fused state developed into an acute mania at about 9 o'clock bunciay morning. He was restrained and about 800 c.c. Fischers Solution was administered intravenously, `the administration occupied about an hour and a quarter at the end of which time he had become quiet and for brief intervals of time appeared rational only to lapse into a somewhat confused state. After a few hours his confused state again developed into an extremely noisy, talkative, but non-violent condition. He appeared to be on the point of becoming violent again and 2% magnesium sulphate was administered intravenously. . He was quieted at once and broke into a profuse perspiration. In this condition he was moved to the Dayton State Hospital. ^ In view of the experience which has been had with these cases up to the present, it seems worth while to point out some things which have been observed. In the first place out of 12 cases of acute mania of this type only one has survived; the others have died of exhaustion in the course of acute manaical attacks. All of the common hypnotics have been used and have proved themselves a disadvantage rather than and advantage. xhey have failed to control the manaical symptoms and in fact they appear to heighten them. This with one notable exception. One case was treated by an interne with apomorphine; whether by accident or not this man fell into a sleep which lasted for 17 hours from which he emerged in a clear mental state, a week later he developed another manaical attack which was controlled in the same fashion. ^ I have been fearful of the use of hypnotics for the reason that it seems to me that by their very nature they should increase the severity of a condition brought about by such a general poison as lead. It has been experimentally shown in animals and at autopsy in the fatal cases that an edema of the brain is a terminal finding. It has seemed advisable to me to make an attempt to reduce the edema and thus if possible to bring back the normal mental state. In addition to that magnesium sulphate is known to be a powerful central nervous system aepressent and I have used it for that reason and for its strong dehydrating powers. xhe success with which such a therapy has been met in the case of this man would appear to me to justify its use. i In our milder cases I have found it quite satisfactory to use salts and alkalies by mouth. We have demonstrated experimentally ^ that by this means the excretion of lead from the body is greatly ^ increased. In bringing about this result I have used the following mixture: sodium bicarbonate - 4 parts, magnesium oxide - one part, and calcium carbonate - one part. This is administered in doses of about 20 grams daily. The quantity being determined by that which is necessary to obtain and maintain a slight alkalinity of the urine. K g 0020857 3 This course of treatment has been so satisfactory that it seems worth while to make note of it. The above suggestions as to the therapy are not interred as a presumption but merely as a statement of previous experiences which you may or may not be interested in pursuing. (Signed) Robt. A.
