During the past two decades the use of gold salts in the treatment of various diseases has become increasingly popular. In particular, the therapy of so-called chronic atrophic arthritis has resulted in an increasing number of favorable reports. In a series of 900 cases, Hartfall, Garland and Goldie1reported apparent cure or striking improvement in 80 per cent. Forestier2records good results in at least 70 per cent of his cases. In the series of Copeman and Tegner,394 per cent showed demonstrable improvement. In general it may be said that cures have been accomplished in an average of 10 per cent of foreign cases and in from 0 to 6 per cent of American cases.4Other diseases which are said to be benefited by gold therapy include lupus erythematosus, cutaneous tuberculids and syphilis.
