COMPARATIVE FREQUENCY OF CHAN CRE AND CEIANCROID.—The relative fre quency of chancre and chancroid is vari ously estimated by different observers. Thus, Fournier finds in his private prac tice that the frequency of chancre as com pared with chancroid is about three to one. The statistics of ten years at one of the large Parisian hospitals show that chancroid comprised about SO per cent. of sores. From clinical experience the writer is inclined to believe that these estimates are fair criteria of the rela tive frequency of the two varieties of genital sore as seen in both private and hospital practice. It must be remem bered, however, that in hospital practice patients with atypical and possibly mixed sores are often lost sight of after they leave the hospital. Doubtless many of these afterward develop syphilis, thus cutting down the percentage of simple chancroids.
Complications of Chancre.—There are some complications of syphilitic chancre that demand attention: 1. First and
simplest we have vegetations or papil lomatous growths: the so-called venereal warts. These result from local irritation combined with heat and moisture, and are identical with vegetations occurring under other circumstances. The writer believes that, while simple genital papillo math are in no sense syphilitic, they, like herpes progenitalis, thrive best on syph ilitic soil. Proper measures of cleanli ness will usually prevent the formation of vegetations. 2. Inflammation of chan cre — pus-infection — sometimes occurs, giving rise to considerable pain and pro fuse purulent secretion. 3. Chancre may be complicated by chancroid, constitut ing "mixed sore," unless the two forms of disease appear in different locations. 4. Chancre may be attacked by phage thena or gangrene.
