Praxis Medical Insights: Syphilis Diagnosis and Management

Syphilis remains a persistent sexually transmitted infection that requires rigorous diagnosis and management to prevent transmission, progression, and severe complications.

HPV Vaccine: What age is too late?

Human papillomavirus (HPV) infects nearly 80% of people at some point during their lives, and while the immune system clears most infections, persistent HPV can lead to genital warts and several cancers (cervical, anal, vulvar, vaginal, penile, and oropharyngeal). HPV vaccination offers strong protection—preventing more than 90% of HPV-related cancers—and is most effective when administered before HPV exposure.
