An intracranial odyssey: pediatric ganglioneuroma arising from the trigeminal ganglion: a case report and review of the literature

Journal of Medical Case Reports
Background Ganglioneuroma represents an uncommon benign tumor arising from the sympathetic nerves, and its development from the fifth nerve is an infrequent entity. Few ganglioneuromas arising from the fifth nerve have been discussed in literature.

VlPAG/DRN Microglia Drive Neuropathic Pain‐Induced Depression via a Defined Neuroimmune Axis

Advanced Science, EarlyView.
Peripheral nerve injury (SNI) induces neuropathic pain, activates midbrain microglia, and triggers an NLRP3–IL‐1β–dependent inflammatory cascade. IL‐1β signals through IL‐1R1 on vlPAG/DRN VGLUT2+ neurons (vlPAG/DRNGlu), inducing hyperexcitability and driving the vlPAG/DRNGlu→BNSTGABA circuit to produce the affective component of neuropathic pain ...

Supra/ para condylar approach for resection of GLOMUS jugular tumor

Interdisciplinary Neurosurgery
Background: Glomus jugulare tumors are rare, highly vascular paragangliomas arising from the jugular bulb. Their intimate relationship with the lower cranial nerves, internal carotid artery, and sigmoid sinus makes complete resection technically ...

Machine Learning‐Driven Design of Multicomponent Bone Inorganic Matrix Mimicking Scaffolds for Osteogenesis Enhanced by Neurogenesis

Advanced Science, EarlyView.
Schematic illustration of development of experimental datasets and algorithm models, screening and preparation of the scaffolds and their applications in vivo. ABSTRACT Bone defects require materials with osteogenic, neurogenic, and angiogenic activity, yet designing such materials within high‐dimensional compositional spaces remains challenging. Here,

Purely Endoscopic Keyhole Supraorbital Approaches for Anterior and Middle Skull Base Tumors

, 2013
Anterior and middle skull base tumors, mainly meningiomas, are usually operated on using a sub-frontal route with a microscope. With modern radiotherapy, the goal of skull base surgery moves from a radical surgery with high rate of side effect to a ...
