Evidence for cellular and solute passage between the brain and skull bone marrow across meninges: A systematic review.

A potential two-way passage of cells and substances between the brain and skull bone marrow may open for new insights into neurological disease. The arachnoid membrane was traditionally considered to restrict cells and larger molecules in CSF from entering the dura and bone marrow directly. However, new data on exchange between brain and skull bone marrow have recently emerged.

Oropouche virus (OROV) is an orthobunyavirus endemic in the Brazilian Amazon that has caused numerous outbreaks of febrile disease since its discovery in 1955. During 2024, Oropouche fever spread from the endemic regions of Brazil into non-endemic areas and other Latin American and Caribbean countries, resulting in 13,014 confirmed infections. Similarly to other orthobunyaviruses, OROV can undergo genetic reassortment events with itself as well as other viruses.

Background: The incidence of spontaneous CSF otorrhea is increasing and knowledge about treatment management is growing.
Objectives: To analyse the cases operated the middle cranial fossa approach (MCFA) for spontaneous CSF otorrhea in our clinic and to evaluate the long-term surgical results in the light of the literature.
Methods: Demographic data, presenting complaints, complications, hearing outcomes, recurrence rates and long-term success of patients operated with MCFA between 2012 and 2022 in our tertiary care centre were evaluated.

An 11-year-old male Bengal tiger () was referred for a 2-week history of ambulatory tetraparesis, generalized ataxia, and hypermetric gait, associated with mild right head tilt and spontaneous proprioceptive deficit on the right forelimb. Neuroanatomical localization was C1-C5 myelopathy; cerebellum-vestibular system involvement was also considered. Hematology and serum biochemistry were unremarkable, although serum vitamin A (0.

Electronic address:
The brain uses a specialized system to transport cerebrospinal fluid (CSF), consisting of interconnected ventricles lined by motile ciliated ependymal cells. These cells act jointly with CSF secretion and cardiac pressure gradients to regulate CSF dynamics. To date, the link between cilia-mediated CSF flow and brain function is poorly understood.
