Neuroinvasion of emerging and re-emerging arboviruses: A scoping review.

Background: Arboviruses are RNA viruses and some have the potential to cause neuroinvasive disease and are a growing threat to global health.

Objectives: Our objective is to identify and map all aspects of arbovirus neuroinvasive disease, clarify key concepts, and identify gaps within our knowledge with appropriate future directions related to the improvement of global health.

Methods: : A scoping review of the literature was conducted using PubMed, Scopus, ScienceDirect, and Hinari.

Stealth invaders: unraveling the mystery of neurotropic viruses and their elusive presence in cerebrospinal fluid - a comprehensive review.

Neurotropic viruses are a threat to human populations due to ongoing zoonosis. A wide array of neurological manifestations can occur most often including parkinsonism, encephalitis/encephalopathy, flaccid myelitis, and Guillain-Barré syndrome. Neuroinvasion occurs through: transneural transmission, blood brain barrier (BBB) dysfunction, and 'trojan horse' mechanism or infected immune cell trafficking into the central nervous system (CNS).

Systemic Lupus Erythematosus in the Elderly That Debuts With an Organic Manifestation of Lupus Nephritis.

Systemic lupus erythematosus (SLE) is a systemic autoimmune condition with many clinical presentations. It is classically seen in young to middle-aged females and can present with cutaneous, renal, serosal, hematological, joint, and/or neurological manifestations at the time of diagnosis or may develop over the course of the disease. Late-onset SLE or SLE in the elderly is a subtype that differs from the classic SLE in age group, clinical presentation, involvement of organs, and severity.
