Treatment.—The most valuable drugs for the treatment of the manifestations of the tertiary period are the arsenical preparations and the iodides of sodium and potassium. On account of their depressing effects, the latter are frequently prescribed along with carbonate of ammonium. The dose is usually a matter of experiment in each individual case; 5 grains three times a day may suffice, or it may be necessary to increase each dose to 20 or 25 grains. The symptoms of iodism which may follow from the smaller doses usually disappear on giving a larger amount of the drug. It should be taken after meals, with abundant water or other fluid, especially if given in tablet form. It is advisable to continue the iodides for from one to three months after the lesions for which they are given have cleared up. If the potassium salt is not tolerated, it may be replaced by the ammonium or sodium iodide.

Local Treatment.—The absorption of a subcutaneous gumma is often hastened by the application of a fly-blister. When a gumma has broken on the surface and caused an ulcer, this is treated on general principles, with a preference, however, for applications containing mercury or iodine, or both. If a wet dressing is required to cleanse the ulcer, black wash may be used; if a powder to promote dryness, one containing iodoform; if an ointment is indicated, the choice lies between the red oxide of mercury or the dilute nitrate of mercury ointment, and one consisting of equal parts of lanolin and vaselin with 2 per cent. of iodine. Deep ulcers, and obstinate lesions of the bones, larynx, and other parts may be treated by excision or scraping with the sharp spoon.

Second Attacks of Syphilis.—Instances of re-infection of syphilis have been recorded with greater frequency since the more general introduction of arsenical treatment. A remarkable feature in such cases is the shortness of the interval between the original infection and the alleged re-infection; in a recent series of twenty-eight cases, this interval was less than a year. Another feature of interest is that when patients in the tertiary stage of syphilis are inoculated with the virus from lesions from these in the primary and secondary stage lesions of the tertiary type are produced.

Reference may be made to the relapsing false indurated chancre, described by Hutchinson and by Fournier, as it may be the source of difficulty in diagnosis. A patient who has had an infecting chancre one or more years before, may present a slightly raised induration on the penis at or close to the site of his original sore. This relapsed induration is often so like that of a primary chancre that it is impossible to distinguish between them, except by the history. If there has been a recent exposure to venereal infection, it is liable to be regarded as the primary lesion of a second attack of syphilis, but the further progress shows that neither bullet-buboes nor secondary manifestations develop. These facts, together with the disappearance of the induration under treatment, make it very likely that the lesion is really gummatous in character.

One of the most striking features of syphilis is that it may be transmitted from infected parents to their offspring, the children exhibiting the manifestations that characterise the acquired form of the disease.

The more recent the syphilis in the parent, the greater is the risk of the disease being communicated to the offspring; so that if either parent suffers from secondary syphilis the infection is almost inevitably transmitted.

While it is certain that either parent may be responsible for transmitting the disease to the next generation, the method of transmission is not known. In the case of a syphilitic mother it is most probable that the infection is conveyed to the fœtus by the placental circulation. In the case of a syphilitic father, it is commonly believed that the infection is conveyed to the ovum through the seminal fluid at the moment of conception. If a series of children, one after the other, suffer from inherited syphilis, it is almost invariably the case that the mother has been infected.

In contrast to the acquired form, inherited syphilis is remarkable for the absence of any primary stage, the infection being a general one from the outset. The spirochæte is demonstrated in incredible numbers in the liver, spleen, lung, and other organs, and in the nasal secretion, and, from any of these, successful inoculations in monkeys can readily be made. The manifestations differ in degree rather than in kind from those of the acquired disease; the difference is partly due to the fact that the virus is attacking developing instead of fully formed tissues.

The virus exercises an injurious influence on the fœtus, which in many cases dies during the early months of intra-uterine life, so that miscarriage results, and this may take place in repeated pregnancies, the date at which the miscarriage occurs becoming later as the virus in the mother becomes attenuated. Eventually a child is carried to full term, and it may be still-born, or, if born alive, may suffer from syphilitic manifestations. It is difficult to explain such vagaries of syphilitic inheritance as the infection of one twin and the escape of the other.

Clinical Features.—We are not here concerned with the severe forms of the disease which prove fatal, but with the milder forms in which the infant is apparently healthy when born, but after from two to six weeks begins to show evidence of the syphilitic taint.

The usual phenomena are that the child ceases to thrive, becomes thin and sallow, and suffers from eruptions on the skin and mucous membranes. There is frequently a condition known as snuffles, in which the nasal passages are obstructed by an accumulation of thin muco-purulent discharge which causes the breathing to be noisy. It usually begins within a month after birth and before the eruptions on the skin appear. When long continued it is liable to interfere with the development of the nasal bones, so that when the child grows up there results a condition known as the “saddle-nose” deformity (Figs. 43 and 44).
