Syphilitic chancre

I need this paper to have 4 pages (APA style). I need three or more articles in this paper (bibliography), the articles must be about the treatment, assessment and diagnosis for this disease. The articles must be 2014 or more advance. No older than 2014. After talking about the treatment, assessment and diagnosis of this disease it can also include other revelant information about it. Thanks
