[Diagnostic workup and treatment of sexually transmitted infections].

There are a number of reasons to exclude sexual transmitted infections (STI). In addition to testing patients presenting with symptoms like discharge, burning when urinating or genitals ulcers, risk-adapted STI tests should be offered. Medical history taking should include sexual orientation and practices, symptoms also of sex partners and symptom-free intervals, previous STI and other medical conditions (especially allergies against antibiotics), previous treatment, vaccination status, contraceptive methods and condom use. Clinical examination depends on anatomy, sexual practices and symptoms. It should always include the inspection of the genital and anal region, the throat and the skin. The goal is to also diagnose oral and anal STI and to provide guideline-based treatment including monitoring of outcome.
