BIBLIOGRAPHICAL NOTICES. La Syphilisation etudiee comme methode curative et comme moyen prophylactique des maladies vSneriennes, par C. Sperino, Agregd a la Faculty M^dico-Chirurgicale de Turin etc. Paris, 1853. Syphilization studied as a Curative and Prophylactic measure in Venereal Diseases, etc. No experiments have excited more interest amongst professional men, than those recently performed in Europe, to test the value of syphilization. Without discussing the question whether syphilis was known to the ancients or not, we may state that an accurate knowledge of venereal diseases cannot be traced back further than John Hunter. His experiments, indeed, repeated and modified by Ricord, have led to the adoption of a system which has served as a basis for the diagnosis and treatment of all venereal diseases. The most important points Ricord established were : 1. That chancre and blennorhagia are two distinct affections. 2. That only indurated chancres are followed by constitutional syphilis. 3. That only indurated chancres require a constitutional treatment. 4. That secondary affections are not inoculable. 5. That syphilis cannot be transmitted to animals. Experiments performed by M. Auzias-Turenne, to test the truth of this last proposition, led him to the observation of the curious fact, that each successive chancre inoculated is smaller than its predecessor. Several inoculations performed on a me- dical student seemed to be followed by the same result; and these gave rise to the doctrine of “ syphilization,” or the inoculation of syphilitic virus as a prophylactic measure against syphilis, and as a therapeutical agent for its cure. “ If,” says M. Auzias-Tu- renne, “ each successive chancre is smaller than its predecessor, must we not ultimately arrive at a point in which the constitution is so impregnated with syphilitic virus as to be incapable of re- ceiving new chancres ?” An individual who has arrived at this point of syphilitic “saturation” he called syphilized ; the pro- cess itself, syphilitic vaccination or syphilization. Had the means of cure hitherto possessed, been found adequate to the treatment of all syphilitic diseases, syphilization would have attracted, at best, but a passing attention. But every one knows how many old syphilitic affections prove refractory under the usual method of treatment, and, therefore, every new agent proposed is always eagerly tried. The hope, too, of acquiring celebrity by discovering a new remedy for syphilis, excited many to enter upon the field of experimentation, whilst others were in- duced by the controversy to repeat Ricord’s experiments on inoculation, with the view of testing their value. Thus originated the experiments on inoculation and the discussions on syphiliza- tion, which have so recently been agitating the profession abroad. Amongst those who, without entering into the subject of syphi- lization, confined their experiments to inoculation, we may men- tion Prof. Waller, of Prague,* M. Vidal de Cassis,f M. Maiso- neuve ;£ amongst those who made use of syphilization on patients, M. Auzias Turenne, M. Diday, of Lyons, and M. Sperino, of Turin. This latter observer, indeed, has recently published a complete work on the subject, containing not only all that up to the time had been written on syphilization, but also a report of ninety-six cases, in which this method was employed with great success. M. Sperino’s work occupies over 800 pages, chiefly made up of the narration of cases. Of its contents, therefore, we can ffive but the merest sketch. * Ueber den contagioesen character der secundaeren syphilis; Prague, 1851. 1 Traite des Maladies Veneriennes; Paris, 1853, tTraite pratique des Maladies Veneriennes.

(Report a M. le Prefet de Police sur la question de savoir si M. le Dr. Auzias-Turenne peut etre autorise a appliquer la Syphilization a l’infirmerie de la Prison St. Lazars ? par M. M- Melier, Ricord, Denis, Conneau et Marchal de Calais), and in Ricord’s letter on Syphilis (Leltres sur la Syphilis; Paris, 1852.) The author states in his preface, that his experiments were performed with the greatest care and precision, and the results given with the loyalty of a man of honor. We are bound to be- lieve him, although some of his facts seem almost incredible. He commences his work with a consideration of the value of ino- culation, as applied to venereal diseases. Inoculation, he says, has been recently practised for seven different purposes : 1. To prove the existence of a syphilitic virus. 2. To distinguish true from false syphilitic diseases. 3. To establish the differences which exist between primary and secondary syphilitic affections. 4. To prove the efficacy of certain therapeutical agents called preservatives. 5. To ascertain if syphilitic diseases could be communicated to animals. 6. As a therapeutical measure against syphilis. 7. As a prophylactic agent against this disease. We pass over the first five propositions (mentioning only that M. Sperino denies the difference between syphilis and blennor- hagia) and revert to propositions six and seven, or the value he attaches to inoculation as a prophylactic and therapeutical agent. Speaking of its efficacy he says in his Report to the Academy at Turin : “ All recent chancres existing in women who were subjected to this treatment disappeared spontaneously a few days after the appearance of the artificial chancres. Indurated syphilitic ulcerations which had existed for two or four years, and had resisted a treatment by mercury, by iodide of potassium, or even by the acid nitrate of mercury, or the Vienna paste, cicatrized rapidly after a few inoculations with pus taken from the recent chancres of other women. Large and deeply rooted virulent ulcerations cicatrised a short time after inoculation, and, what is more astonishing, I saw in a woman who had a chancre and two inguinal buboes, in both of which, distinct fluctuation could be felt, the pus absorbed and disappear in a few days after the inoculation on the abdomen of several artificial chancres. Mucous tubercles existing at the same time with the chancres, disappeared under the powerful action of inoculated virus. A large ulcer situated on the posterior portion of the pharynx, healed up after the 5th inoculation. In one woman herpiginous ulcers having their seat on the right leg cicatrized rapidly, whilst, at the same time, the pains in the frontal bone disappeared after the development of the arti- ficial chancres. The harmlessness and the advantage of syphilitic inoculation, became at last so well known to the patients, that they themselves, forgetting their reluctance to the first trials, begged me to syphilise them, as their companions had been thus cured.” The method of producing the artificial chancres consists in puncturing the skin with a lancet, on which venereal matter has been collected. The place best suited is the thigh or abdomen. The chancres thus produced do not differ in appearance from ordinary chancres, except that, after repeated inoculations, they become smaller. The number of inoculations necessary to pro- duce syphilization we do not find mentioned; in some cases five, in others sixty or more seem to have been necessary. The cica- trices of these artificial chancres are very superficial, except when they become gangrenous. During the treatment by syphili- zation, baths and purgatives were freely employed ; the cicatrices were dressed with simple cerate. Now follows the report of ninety-six cases cured by syphiliza- tion. To attempt a full analysis of these cases would carry us far beyond the limits assigned to a review; we therefore select but one of the most striking and interesting. (Observation I, p. 116.) “ Julia P., age 22, of a sanguine-lymphatic temperament and excel- lent constitution, entered the hospital on the 29th of January, 1851.— She has on her body several chancres, viz., an urethral chancre, evidently indurated, a chancre in the fossa navicularis in size about 12 millimetres and also indurated, and two large and irregular chancres situated on the sides of the urethra. It is the second syphilitic infection under which she labors. In 1845 she had an indurated chancre on the vulva, accom- panied with a bubo in the groin, and mucous tubercles around the arms and vulva. She was then treated with 40 mercurial inunctions. Con- stantly returning vegetations obliged her to remain in the hospital during the whole of the year 1846. As excision and cauterization did not pre- vent their reproduction, I subjected her to a new treatment by inunction. But even this did not triumph over the “ vegetative” power of the vulvo-vaginal mucous membrane. The vegetations finally yielded to deep incisions and repeated cauterizations. Since 1845 up to this day, she has been sent nine times to the hospital with chancres, twice compli- cated with urethral blennorhagia, and which have always been cured by a simple local treatment. 20z7z of January, 1851, (the day she entered the hospital,) an in- oculation was made on her left thigh, with the pus taken from her other chancres ; a large pustule was the result, which soon changed into a syphilitic ulcer ; the inoculation was repeated on the 31st, and another pustule was the result. 27
