The fact that a trauma may light up a syphilitic process is illustrated in a case that came to the Psychopathic Hospital, in which a Syphilitic Lesion developed in the skull at the Site of Skull Injury.[[119]]

A case of Occupation-neurosis[[120]] that might be interpreted as a syphilitic neuritis is presented. The case is still in doubt as to its scientific evaluation.

The workmen’s compensation group of syphilitic cases is of extraordinary general interest since it indicates that employers may well be on the lookout not to employ known syphilitics unless fortified by special insurance arrangements. Whether in future employers may desire to employ only W. R. negative workmen is one of the highly complicated questions re workmen’s compensation and health insurance.

But the problems of neurosyphilis are not merely medicolegal and broadly public or social. The most appealing difficulties lodge within the bosom of the family. Now and then a case of Incompatibility of Temperament, perhaps complicated by alcoholism, occurs which tests prove to be Neurosyphilitic.[[121]]

Special attention should be drawn to a certain Neurosyphilitic Family[[122]] in which both parents and five children showed a variety of syphilitic diseases, including syphilis without apparent neural complications, paretic neurosyphilis, juvenile paresis, aortic aneurysm, achondroplasia and caries of the spine, and an as yet indefinite neurosis. There was a sixth child that died shortly after birth, as well as three stillborn.

One cannot conclude from the normal[[123]] look of a neurosyphilitic’s family that the normal-looking members are not syphilitic, as illustrated by the family of our draughtsman.

The most intricate social complications may arise. We present a case of a syphilitic man (a well-to-do merchant) who was apparently being goaded into a second marriage[[124]] because he was continually being charged with having caused his first wife’s death. This he had actually done in a certain sense because his wife had died of general paresis, having contracted syphilis from him.

In the fifth section on THERAPY, we have attempted to outline some of the principles and problems that arise in the treatment of neurosyphilis. Enough has probably been said concerning the attitude of optimism or pessimistic nihilism that may be adopted toward the whole subject. It must be borne in mind, however, that a great deal of the work on treatment of neurosyphilis is still in the experimental stage. As a rule, each case must be considered separately and individually and the prognosis can be made satisfactorily only after treatment has been given. This section contains a group of cases that have been treated rather intensively and the results of this treatment are indicated. The section is introduced by five untreated cases, the brains and cords of which have been studied post mortem. These illustrate the pathological conditions which we have to meet, and from these examples we can draw the theoretical conclusion that some cases are beyond the aid of therapy on account of the brain destruction. Others, in which the symptomatology bespeaks just as grave a situation, turn out on autopsy to have very little actual damage to the brain tissues and therefore should theoretically at any rate be amenable to antisyphilitic therapy.

In order to get any adequate conception of the possibilities of therapeutic results in cases of neurosyphilis, one must consider the pathological changes that occur and how far these changes are reparable. In cases in which the destruction of tissue is marked, it is, of course, out of the question to expect to get any marked clinical improvement. A case of spastic hemiplegia[[125]] in paretic neurosyphilis is given with the autopsy findings as an illustration of irreparable damage that may occur to the parenchymatous structure, thus precluding any chance of functional recovery.

On the other hand, there is a group of cases in which the symptoms may be exceedingly severe and yet the actual destruction of tissue be almost nil. This point is illustrated by a case[[126]] in which total duration of symptoms terminating in death was only 22 days. At autopsy there was very little in the way of macroscopical lesions, and microscopically there was no marked evidence of destruction in the parenchymatous tissue. The lesions were represented chiefly by perivascular infiltration. According to all our modern ideas, this type of reaction is resolvable under antisyphilitic treatment. Though this case was one of very short duration, similar pathological pictures may be obtained in cases of considerably longer standing. It is also of great importance to remember that symptomatically such a case may be in no way distinguished from a case with marked atrophy.
