CONTENTS. I. Introduction. II. General Considerations of Local Iodine Therapy. III. Special Considerations of Local Iodine Therapy. IV. The Selection of Iodine Preparations for Practical Use. V. Method of using Regional Iodine Therapy in the Correction of Various Pathological Conditions. I. Introduction. In presenting to the veterinary profession this treatise on Regional Iodine Therapy, I do so with the object of bringing into the light certain clinical facts that have to do with the topical application of iodine in veterinary patients, and to discuss, from the standpoint of the clinician, those particular pathological conditions to which these facts apply. It will be further my purpose to point out to the reader the special indications for topical iodine medication which have, in the past, been overlooked by the practitioner of veterinary medicine. Throughout the treatise I shall confine myself to the exposition of only such matter as I have found to be compatible with the practical phases of veterinary science in the conduct of my own practice. M. R. S. Milwaukee, Wis. March, 1919. II. General Considerations of Local Iodine Therapy. While it is a fact that iodine is one of the most popular of the many medicinal agents used by the practitioner of veterinary medicine and surgery, it also is a fact that iodine--more so than any other agent--is frequently used in pathological conditions and under circumstances that lack every scientific indication for its application. To a certain extent this is true of almost any medicinal agent in common use, even those whose field of applicability is less broad than that of iodine; but it is especially noteworthy in the use of iodine. Iodine does not differ from any other therapeutic agent with regard to individual indications for its application; it has these as prominently marked as have the alkaloids, physiologically. But it does differ from almost all other therapeutical agents in the fact that, it has such a vast field of applicability in which the indications for its use are supported solely by clinical evidence and in which its action defies all attempts at an explanation of results attained, on a physiological basis.
