Secondary glioblastoma metastasis outside the central nervous system in a young HIV-infected patient.

Glioblastoma is the most common adult primary brain tumor that occurs in the central nervous system and is characterized by rapid growth and diffuse invasiveness with respect to the adjacent brain parenchyma, which renders surgical resection inefficient. Although it is a highly infiltrative tumor, it is rarely disseminated beyond the central nervous system, wherein extracranial metastasis is a unique but rare manifestation of this kind of tumor. It is very common for acquired immunodeficiency syndrome (AIDS) patients to be infected with the human immunodeficiency virus (HIV), which suggests that a possible association between HIV infection and tumor development exists.

Biomarkers in Spinal Cord Injury: from Prognosis to Treatment.

Spinal cord injury (SCI) is considered an incurable condition, having a heterogenous recovery and uncertain prognosis. Therefore, a reliable prediction of the improvement in the acute phase could benefit patients. Physicians are unanimous in insisting that at the initial damage of the spinal cord (SC), the patient should be carefully evaluated in order to help selecting an appropriate neuroprotective treatment.
