Primary Intracranial Gliosarcoma: Is It Really a Variant of Glioblastoma? An Update of the Clinical, Radiological, and Biomolecular Characteristics.

Gliosarcomas (GS) are sporadic malignant tumors classified as a Glioblastoma (GBM) variant with IDH-wild type phenotype. It appears as a well-circumscribed lesion with a biphasic, glial, and metaplastic mesenchymal component. The current knowledge about GS comes from the limited literature.

A novel 3D anatomical visualization system to avoid injuries of nerves in retrosigmoid approach.

The retro-sigmoid approach (RA), widely used during different neurosurgical procedures, is burdened by the risk of injuries of the nerves that cross that region contributing to possible postoperative complications. By using, anatomage table (AT), a novel 3D anatomical visualization system, we described the nerves passing through the retromastoid area including the great occipital nerve (GON), the lesser occipital nerve (LON) and the great auricular nerve (GAN), and their courses from the origins, till terminal branches. Moreover, using dedicated software, we measured distances between the nerves and well-recognizable bony landmarks.

Percutaneous intradiscal injection of radiopaque gelified ethanol: short- and long-term functional outcome and complication rate in a consecutive series of patients with lumbar disc herniation.

Lumbar disc herniation (LDH) is a common cause of low back pain (LBP) and/or radicular pain (RP). Over the years, different therapies have been proposed to treat symptomatic LDH, including different minimally invasive techniques and open surgical methods. Recently, percutaneous intradiscal injection of radiopaque gelified ethanol (RGE) DiscoGel has emerged as an effective therapeutic option in patients with LDH.

The Legacy of Rita Levi-Montalcini: From Nerve Growth Factor to Neuroinflammation.

Rita Levi-Montalcini was an extraordinary personality and with her profession she made a tremendous contribution to humanity. Doctor, Nobel laureate for medicine, neuroscientist, she contributed, thanks to her research, to improve the knowledge of the nervous system. She discovered the nerve growth factor, which is applied in various fields of neurology, concerning neurodegenerative diseases.
