Ordinarily, one might content himself regarding the case of John Doran as one of idiopathic epilepsy with mental defect or deterioration. However, the frontal bosses, suggestive teeth, the flattened bridge of the nose, the roughened tibiae, and the old scars, though singly not of great significance, collectively make one suspicious. Despite the family physician’s belief that John could not have acquired syphilis from the parents, the infection seems entirely possible despite the fact that no symptoms developed early thereafter. The W. R. in this case proved positive in both blood serum and spinal fluid. 1. What is the relation of trauma to this case of JUVENILE NEUROSYPHILIS? Probably none. 2. What would be the effect of treatment? For a number of years John Doran was lost sight of. He was, however, treated, according to our information, with intraspinous injections of salvarsanized serum, whereupon his convulsions shortly ceased. He has been recently examined mentally once more, and still grades as feebleminded. He still has violent outbreaks of temper. 3. Is such a case as Doran typical? Shanahan has investigated conditions at Craig Colony. There were 22 out of 886 epileptics (at Craig Colony) or 2½%, who showed a positive W. R. Nine of these cases were regarded by Shanahan as cases of epilepsy actually caused by syphilis. Viet had found 7%, and Bratz and Lüth 5% of constitutional epileptics to be syphilitic, but the data of these German authors were obtained before the era of Wassermann tests. =Adrenal tuberculosis complicating juvenile paretic neurosyphilis (“juvenile paresis”). Autopsy.= =Case 80.= When James Arnold appeared at the Danvers Hospital in his 22d year, he looked as if he were but 12 or 14 years of age. He was excessively fat but of fair muscular development. The left eye diverged outward, and the left pupil was smaller than the right. An odd feature was a high degree of pigmentation of the skin of the genitalia and the groins (the axilla, the mammillary areas, and the oral mucosæ were free from pigmentation). =Physically= speaking, the patient was practically normal. =Neurologically=, however, there was much of interest, in the light of which the clinical history was of value. It seems that after an apparently normal early childhood, the boy had begun, at the age of 11, to experience difficulty in carrying out every-day school tasks; and after this his mental capacity had slowly but progressively deteriorated. The deterioration was not merely intellectual, but the boy became dishonest and untrustworthy and developed a number of untidy and uncleanly habits, behaving at the age of 16, as the parents stated, like a child of six.
