Page 13 - ... most instances with propriety, introduced. The first, or introductory chapter, affords some very useful hints on the general characters and management of their diseases; the remarks on diagnosis are especially deserving of notice. The chief point is to determine the elementary lesion ; we have then merely to compare the disease with the few which possess the same elementary character. If the elementary lesion is unaltered, we have only to determine the order to which it belongs, and this is usually...
Page 16 - ... by thick, rough, yellow scabs, which cover a large portion of the extremities, especially the legs, and when they fall off, expose superficial excoriations; the latter discharge a purulent secretion, which dries up, and forms fresh scabs, these being the most characteristic features of the disease. Now it is easy enough to tell at once that this is a pustular affection, but not so easy to determine its species. The disease is evidently neither variola nor vaccinia ; the pustules of ecthyma are...
Page 15 - The fluid of a vesicle may, for example, dry off and leave a small incrustation ; a pustule may be converted into a scab, and the latter give way to an ulcer ; hence it is necessary that we should study these secondary lesions, and know to what primary characters they correspond. Incrustations may succeed vesicles, vesicopustules, and papules ; scabs occur in most pustular diseases, and ulceration may be a consequence of rupia, ecthyma, &c.
Page 15 - In cases like the foregoing, we must first ascertain the nature of the secondary lesion, then determine its corresponding primary element, and finally pursue the course just pointed out. For example, a patient comes to us with a disease of the skin...
Page 16 - The disease is evidently neither variola nor vaccinia ; the pustules of eethyma are large, isolated, and frequently covered by black, tenacious scabs, which end in ulceration ; it is neither acne nor mentagra, the pustules of which rarely ever give rise to scabs. The only affections, then, that remain are impetigo and porrigo, and we have merely to compare the character of these two species in order to decide. It is unnecessary to enumerate here the signs by which we know that the disease is not...
Page 69 - And, on the other hand, distempers which Nature has plainly brought together and connected by striking analogies and resemblances, the methodical arrangement of Willan and Bateman puts widely asunder (WATSON).
Page 67 - ... form in which the cutaneous (gouty) disease manifests itself, and that there are records of many cases in which the skin and jointaffection are alternated. Sir Thomas Watson,* speaking of psoriasis and lepra says, " I believe that they sometimes depend upon the presence, or the generation, of an excess of acid in the system ; and that they are often cured by alkaline remedies, I am sure.
Page 16 - In some cases different elementary lesions occur in the same subject,, bat even here we always find some predominant form, of which the rest are but complications. However, it may happen that we cannot ascertain at once the true nature of the disease. This occurs in certain chronic affections, where the elementary character gradually disappears, and seems confounded in a different order of phenomena. Even here a sudden exacerbation of the disease, or a return to health, may develop its primary character.
Page 36 - ... Impetigo and Scabies, there is occasionally an intermixture of lymphatic vesicles. And, lastly, the natural progress of many eruptions is to assume a considerable variety of aspect ; so that it is only at some particular period of their course that their character is to be unequivocally decided. Thus in the commencement of Scabies papuliformis and lymphatica, the eruption is of a vesicular character, although its final tendency is to the pustular form : and, on the contrary, in all the varieties...
Page 35 - ... of impetigo, and, in another, the vesicles of eczema. Again, the diseases which commence with one generic character, are liable occasionally to assume another, in the course of their progress :—thus, some of the papular eruptions become scaly, and still more frequently pustular, if their duration be long protracted ; the Lichen simplex and circumscriptus, for instance, sometimes pass into psoriasis; the Lichen agrius and Prurigo formicans are occasionally converted into impetigo ; and the Prurigo...
