In angiose hypertrophy the swollen membranes will contract under a mild {42} current of electricity or by change in the position of the body. Both chambers are rarely involved at the same time. Reflexes are of infrequent occurrence. Obstruction to nasal respiration due to a deflected septum arises from causes which are insignificant and do not affect the constitution. The genuine influenzal or catarrhal element is absent. In an inflamed soft nasal polypus an attempt at inspiration will, as a rule, detect the presence of the growth. In diffuse multiple polypi the case is different. Many persons who are reputed to take cold readily, or who may be said never to be free from cold, are really sufferers from neglected polypi. Persons suffering from atrophic catarrh always speak of an exacerbation of their symptoms as a fresh cold, and describe the disease itself as a cold. The sense of fulness, the throbbing, the heat, and the characteristic discharge of coryza are absent. A fresh cold in atrophic catarrh is an attack of inflammation (often catarrhal in character, it is true) which affects the involved surfaces, but is attended with an increase of plastic exudation and accompanying fetor. It is a common occurrence for patients who have had a cautery application made or a polypus removed to return after a few days' absence with the report that they have contracted a cold. While the condition may be an attack of acute coryza, the chances are in favor of the symptoms being excited by the manipulation or the reaction from the operation. The symptoms are mild in character. TREATMENT.--The treatment of coryza is both local and constitutional. The local treatment consists in applications of agents which tend to constrict the vessels of the nasal mucous membrane. In the first rank of such agents may be named cocaine, which in a 2 per cent. or a 4 per cent. solution will often give notable relief by overcoming the sense of obstruction. Individuals will be found in whom the effect is of short duration, and in some persons I found the medicine to have no effect whatever. In more favorable subjects the relief will be acknowledged for a period varying from four to six hours. Next in rank may be named a current of constant electricity (say from six to ten cells) passed through the cheeks. Should neither of the above-named agents be available, inhalations of iodine vapor, a few drops of chloroform rubbed upon the palms and inhaled, or the inhalation of the spirits of ammonia may be recommended. Toward the later stages of the disease detergents and mild astringents are well borne. The constitutional treatment includes the administration of diaphoretics and minute doses of opium, especially in the early stages of the disease. Coryza is commonly self-limited, and by far the larger number of cases do not come under the care of the physician. Chronic Nasal Catarrh.
