Upon investigation, it appeared, however, that a year before the attack above described, the patient had been examined and both blood and spinal fluid found positive to the W. R. At that time, treatment, consisting of intravenous injections of salvarsan and intraspinous injections of salvarsanized serum (Swift-Ellis), had been instituted. Whereupon the laboratory tests had become negative, as above stated, and there had been no alleviation of the symptoms. 1. How can Rokicki’s normal deep leg reflexes be explained? The abolition of the deep reflexes is of course due to lesions properly localized. It is probable that this particular case of tabes dorsalis is more truly “dorsal” than most cases; for most cases exhibit lesions involving regions lower than the dorsal. Both in these dorsal cases and in certain rare cases of cervical tabes, the deep leg reflexes are preserved. (See cases Green (30) and Halleck (31).) 2. What is the mechanism by which a characteristic gastric crisis is produced? The mechanism is unknown. Some endeavors have been made to meet gastric crises by surgery of the posterior roots, on the assumption that the irritation causing the pain was located either in the posterior ganglion or in the passage of the nerve through the meninges. In only a few instances, however, has the result been what was desired. In many instances the gastric crises and pain continued uninterrupted and in addition came discomfort due to the lack of sensation in the part supplied by the severed nerve. At present this treatment is seldom carried out. 3. Should antisyphilitic treatment be continued in such a case? As far as our present knowledge of syphilis goes one would hesitate to suggest further antisyphilitic treatment, feeling that the active process had been entirely stopped as suggested by the absence of any positive findings either in the blood serum or in the spinal fluid. We should perhaps conclude that there was no more activity in this case and that the crises were due to the changes that had already taken place in the nerve tissue and which could no longer be changed. =The literature is in doubt concerning (in fact is preponderantly against) the success of treatment in PARETIC NEUROSYPHILIS (“general paresis”). Our experience has yielded a number of apparently successful results through systematic intensive intravenous salvarsan therapy. Example.=
