If the reader has made an effort to follow me in what I have said in the foregoing chapters of this treatise, he will have no difficulty in applying, to cases occurring in his practice, many of the suggestions offered. In this, the closing chapter of the treatise on regional iodine therapy, I intend to refer to a small number of conditions, in the handling of which I have found great satisfaction in the use of the preparations heretofore mentioned, and, at the same time, I shall endeavor to explain my own particular methods of using the preparations. I have already disposed of the manner in which the applications of tincture of iodine are made, previous to incision of the integument, in surgical operations. Aside from this quite common use of this preparation, I have found tincture of iodine of great worth as an application to calk wounds in the coronary region of the equine foot. When the injured horn has been pared away under the wound in the coronary band, and the loose particles of flesh and hair cleaned away, the wound is freely painted with pure tincture of iodine. This painting is to be repeated several times daily, until recovery takes place. Severe infections rarely occur if the applications are begun within a few hours after the accident occurs. Whenever tincture of iodine is used, for the correction of an abnormality in the horse and cow, it must be applied very liberally if the effect is desired with any degree of promptness. This, together with the fact that the tincture is quite irritating to the skin of animals--a fact that precludes an extensive course of treatment with this preparation--makes iodine, in this form, an agent that is chiefly of use in acute conditions, and it is, therefore, the agent of choice to act as an adjunctive treatment to the internal handling of such conditions as septicemia, strangles, distemper, parotitis, lymphangitis of a localized character, and acute inflammations in tendons, ligaments, and synovial bursae. In any of these conditions, it is best applied with a small, rather stiff brush, painting it liberally, over the parts involved, several times daily. If the parts become very much irritated from these applications, the treatment must be stopped and the area treated with a coating of vaseline or lard. The oily preparations of iodine are especially useful in various skin diseases, ring-worm, and the parasitic form of scratches in horses. The secret, in the successful handling of these conditions with oily preparations of iodine, lies in the abstinence from water; the parts should be given one thorough washing, when treatment is first begun, after which no more water should be applied. If the parts need cleansing, while the course of treatment is under way, it should be done in a dry manner, with clean cloths or cotton wads.
