Attention will often be required to the various scorbutic complications, especially stomatitis, which is always a source of discomfort and suffering. One of the best local applications for this is pencilling the parts with a solution of nitrate of silver, which often affords marked relief. Mouth-washes, composed of solutions of chlorinated lime, potassium permanganate, carbolic acid, are beneficial by suppressing foul odors, exercising local stimulative action upon the gums, and promoting healing. Should ulceration attack the legs, as is often the case, the application of mild astringents and stimulative ointments will be all that is required. The parts should, of course, be kept clean and protected from irritation by protective dressings.
Hemorrhages from the nose, gums, stomach, bowels, or into the serous cavities should be treated upon the general principles applicable to their character, as the local use of cold, astringents, and the internal administration of hæmostatic agents—lead acetate, ergot, tincture of iron, and other remedies, vegetable and mineral, of this class. In desperate cases effusions into the chest, threatening death by interfering with the respiratory and circulatory organs, may render operation necessary as the last resort for their removal.
During the treatment it is important to obviate any sudden or severe strain upon the heart by premature movements or exercises, as this is fraught with danger.
PURPURA.
BY I. E. ATKINSON, M.D.
It has been customary with authors to describe under the general heading Purpura a number of affections presenting as a common symptom the extravasation of blood into the tissues, more especially of the skin and mucous membranes, quite irrespective of etiological or pathological considerations. Thus, the tiny ecchymoses caused by the bites of fleas have been denominated purpura pulicosa; the larger bruises resulting from external violence, purpura traumatica; the extravasations occurring in the course of scurvy, purpura scorbutica; those encountered in malignant small-pox, purpura variolosa; and so on. These affections, differing widely in nature, possess as a common symptom the escape of blood from the vessels into the tissues. It is evident, therefore, that in the sense often employed the term purpura is used to describe a symptom or symptoms common to a variety of non-related maladies.
If there be a peculiar morbid process having for its constant and characteristic symptom the spontaneous escape of the blood from the blood-vessels, it is plain that interstitial hemorrhage from external violence or from the action of a definite poison circulating in the blood and disorganizing it and its containing vessels, as in phosphorus-poisoning, or from the influence of certain zymotic diseases, should not be designated by the title properly belonging to a substantive malady. The question, therefore, is: Are there groups of symptoms indicating morbid action of definite character, but of varying intensity, to which the name purpura may with propriety be applied?
