The Nirvanol Treatment of Chorea.

Since the introduction of nirvanol in the treatment of chorea by Roeder' in 1919, it has been used by many workers, particularly in Germany, and it was introduced into this country in 1929 by Poynton and Schlesinger2. Details of its composition and general use may be found in many papers, notably those of Lesigang3 in German and Poynton and Schlesinger in English, and it is the intention in the present paper to discuss those points in which there may be difference from papers already published, thus to some extent avoiding unnecessary recapitulation. During 1929 a number of cases were treated at the East London Hospital for Children, and of these eleven have been already published by Whitaker4, but, by arrangement with him, they have been included in the present series, as the present writer was able to follow them from the beginning and to see them as out-patients later, thus being able to present a more complete picture.
