Abnormal signaling through the platelet-derived growth factor receptor (PDGFR) has been proposed as a possible mechanism of spinal cord glioma initiation and progression. However, the extent of PDGFR expression in human spinal cord gliomas remains unknown. In this study we perform immunohistochemical analysis of PDGFRα expression in a series of 33 primary intramedullary spinal cord gliomas of different types and grades. PDGFRα was seen to be expressed in a significant subset of these tumors across all major glioma types including ependymoma, oligodendroglioma, pilocytic astrocytoma, astrocytoma, and glioblastoma. These results support the hypothesis that growth factor signaling through the PDGFR may be important for the development of at least a subset of human spinal cord gliomas. Further studies investigating the prognostic significance of PDGFR expression as well as the role of PDGF signaling on the development of intramedullary spinal cord gliomas are warranted.

Background: Although transcutaneous spinal cord stimulation (tSCS) has been suggested as a safe and feasible intervention for gait rehabilitation, no studies have determined its effectiveness compared to sham stimulation.
Objective: To determine the effectiveness of tSCS combined with robotic-assisted gait training (RAGT) on lower limb muscle strength and walking function in incomplete spinal cord injury (iSCI) participants.
Methods: A randomized, double-blind, sham-controlled clinical trial was conducted.

Background: Repetitive neonatal painful procedures experienced in the neonatal intensive care unit (NICU) are known to alter the development of the nociceptive system and have long-lasting consequences. Recent evidence indicates that NICU stay affects the methylation of the opioid receptor mu 1 encoding gene (Mor-1). Additionally, a preclinical model of neonatal procedural pain established lower adult post-operative MOR-1 levels in the spinal cord.

Parkinson's disease (PD) is a significant source of morbidity, especially with an aging population. Gait problems, particularly freezing of gait (FOG), remain a persistent issue, causing falls and reduced quality of life without consistent responses to therapies. PD and related symptoms have classically been attributed to dopamine deficiency secondary to substantia nigra degeneration from Lewy body (LB) and Lewy neurite (LN) infiltration.

Spinal arteriovenous(AV) shunt disease is rare, although many neurosurgeons may encounter patients with the disease. Recently, the pathological findings and classification of spinal AV shunt disease have been well described. The fundamental treatment of spinal AV shunt disease involves interruption of the shunt, which is achieved by endovascular treatment or direct surgery.

This study reviews the diagnostic criteria and treatment strategies for spinal malignant gliomas, particularly glioblastoma with -wildtype and diffuse midline gliomas with H3-K27 alteration, according to the World Health Organization 2021 classification. Surgical resection remains challenging owing to the diffuse nature of these tumors. Even with the Stupp regimen(temozolomide and radiotherapy), the prognosis remains poor, with an average survival of 12 months.
