Coryza is one of the most characteristic, and at the same time one of the most important, of these in its influence on the health of the child. It is due to the same condition of the mucous membrane lining the nasal fossæ as manifests itself simultaneously or soon afterward on the skin in the shape of erythema, roseola, or papules; in other words, it is a hyperæmia with papillary infiltration. Now, on the skin this condition, except in so far as it indicates the presence of a grave constitutional disease, is of no special importance. In the nostrils of a sucking infant, already debilitated and impoverished by the anæmia of syphilis, and depending upon its nutrition for the continuance of the miserable flickering life which was its original endowment, the same condition assumes the gravest significance.
The excessive supply of blood to the parts induces a catarrhal condition which shows itself in a thin, watery discharge, which, as the child during sucking is compelled to breathe through the nose, is rapidly dried into crusts. These become adherent, fill up and lessen the channel for the passage of air, and in so doing add to the rapidity and force of the respiration through the nose, and thus increase the tendency to the deposit of these crusts. The peculiar nasal, noisy respiration of the child has given the affection the popular name of snuffles. As the child can no longer breathe, or can breathe only with great difficulty, while sucking, it takes the breast only to drop it again immediately on account of impending suffocation.75 As the disease progresses ulceration occurs beneath the crusts, and often involves the entire thickness of the delicate mucous and periosteal layers underlying the thin bones of the nose; perforation of these bones results, sometimes with caries to such an extent as to cause an entire loss of the nasal septum, with flattening of the nose—a symptom comparable to one which sometimes occurs in the tertiary period of adults, but produced, as we have seen, by other causes. In adults syphilitic caries and necrosis are usually due to lesions seated primarily in the osseous or subperiosteal tissues; in the child, at least in this instance, these tissues are involved secondarily.
75 For an admirable description of the mechanism of this and other symptoms of coryza see Diday, op. cit., pp. 78-83.
Erythema, or roseola as it is differently called, is apt to present itself about the second or third week76 after birth. As in the adult, it begins upon the abdomen in the form of little oval, circular, or irregular spots, dull red in color and disappearing upon pressure. Later the color becomes deeper, the eruption extends to the trunk and limbs, and, as exudation and cell-proliferation succeed to simple capillary stains, it ceases to disappear when pressed upon. It is often moist, owing to the thinness of the epidermis, sometimes excoriated. Occasionally it is confluent, and covers large areas with an almost unbroken sheet of deep-red color.
76 Bassereau gives an instance of its occurrence within three days.
The diagnosis in the early stage is often difficult on account of the resemblance to the simple erythema of infancy. As the disease progresses, however, maculæ form here and there; the cell-infiltration involves the papillæ, several of which coalesce, forming flat papules; the nutrition of the superficial layers of the epiderm is interfered with, especially where it is thick, as on the palms and soles, and the eruption in those regions becomes scaly, and then the diagnosis is not difficult.
Papules and Mucous Patches.—In the ordinary evolution of the disease the next manifestation is usually the development of papules upon the general cutaneous surface and of mucous patches on the tongue, lips, and cheeks—probably also on other mucous membranes not exposed to examination. The papules are apt, for the reason already mentioned—the thinness and moisture of the skin—to be of the broad, flat kind, especially, as in the adult, in those regions where the elements of warmth and friction are superadded to the moisture, as in the folds of the skin about the genitalia, the neck, the flexures of the joints, etc. They are then moist, covered with a grayish secretion or a thin crust, and are in reality mucous patches. Occasionally they take on a little hypertrophy and develop condylomatous excrescences which closely resemble the simple acute condylomata of infants. In syphilis, however, the growth springs from a previously existing papule, which is not apt to be solitary, there being others in the neighborhood which will probably establish the diagnosis. The syphilitic condylomata also have a peculiar fetid discharge, resembling that of mucous patches and more or less characteristic.77

Mucous patches in the infant are among the most important of the early syphilitic lesions—not to the child itself, because they do not materially affect its health, save in those exceptional instances where they are accompanied by a marked degree of stomatitis, and thus interfere with its nursing. Their importance is due to the fact that they are almost constantly present, and they are thus by far the most frequent vehicle of contagion from the child to its nurse or to others with whom it may come in contact. At times they do not differ materially from the same lesion occurring in the adult, but lose much sooner their epithelial investment (on account of the delicacy and comparatively slight attachment of the epithelium at this stage), and they then appear as oval or irregular red, slightly depressed spots, distinct or coalescing, ulcerating or oftener covered by a false membrane. They especially affect the angles of the mouth and the sides and dorsum of the tongue; and indeed their disposition to select the former situation constitutes a diagnostic difference between them and non-specific stomatitis which is to be found in the sulci between the gums and cheeks and on the gums themselves—locations rarely invaded by mucous patches.78 When the latter are ulcerating or are concealed by diphtheritic membrane, and are situated on the tongue, they may be mistaken for either simple or parasitic stomatitis. The diagnosis can often be made by the presence of other syphilitic symptoms—coryza, erythema, and especially papules. In their absence, however, it must be remembered that in simple stomatitis, the inflammation not being limited to special areas, the whole tongue is apt to be involved or a much larger portion of the buccal mucous membrane; and as there is no marked tendency to cell-proliferation in these cases, the accompanying exudation is apt to be serous or watery and to result in vesiculation—a condition never seen in syphilitic stomatitis. In the parasitic disease, too, the inflammation is less localized, there is more swelling and congestion, and the false membrane is said to be of a whiter color.
