The prevalence and risk-factors of oral HPV DNA detection among HIV-infected men between men who have sex with men and heterosexual men.

Human papillomavirus (HPV)-associated oropharyngeal carcinomas are becoming more common with epidemiological impact on human immunodeficiency virus (HIV)- positive individuals. We evaluated prevalence and risk factors for oral HPV DNA among HIV-infected men who have sex with men (MSM) or heterosexual men. This cross-sectional hospital-based study included 255 HIV-infected men with different sexual orientation 142 MSM and 113 heterosexual men, who answered a self-administered questionnaire on sociodemographic, clinical and behavioural data.

It is spread worldwide, and there has recently been an increase in its incidence. Neurosyphilis (NS) can have a variety of presentations; meningovascular NS is a specific affection of the Treponema which occurs in an early stage after the primary infection, causing an inflammatory arteriopathy which may result in an ischemic stroke.

An Unusual Case of CMV/EBV Ventriculoencephalitis with Evolution to Primary Central Nervous System Lymphoma in HIV-Positive Patient.

Epstein-Barr virus (EBV) is a well-known cause of different types of malignancies particularly Burkitt's lymphoma, nasopharyngeal carcinoma, Hodgkin's lymphomas, and non-Hodgkin's lymphomas including primary central nervous system lymphoma (PCNSL). A higher tendency of malignant transformation associated with EBV has been noticed in immunocompromised patients, such as human immunodeficiency virus (HIV) infected patients. The rapid and effective immune reconstitution is crucial to prevent PCNSL in HIV-positive patients.
