We sought to describe the clinical characteristics and management of patients with discordant syphilis serology. METHODS From August 2007-October 200...

The clinical significance of discordant serology (CIA(+)/RPR(-)) for maternal and neonatal outcomes is...
متن کاملSyphilis serology in patients with primary syphilis and non-treponemal sexually transmitted diseases in southern Africa.
