Study Design: Two case reports of telangiectatic osteosarcoma treated with complete segmental resection of the spine, including the spinal cord.
Objectives: To report the en bloc tumor excision, including the spinal cord, for telangiectatic osteosarcoma, and discuss the indication of cord transection and influence after cutting the spinal cord.
Summary Of Background Data: To our knowledge, there are no previous reports describing telangiectatic osteosarcoma of the spine and the subsequent en bloc excision of the spine, including the spinal cord.
Methods: The clinical and radiographic presentations of 2 cases with telangiectatic osteosarcoma are presented. Because these 2 cases already had complete paralysis for at least 1 month, it was suspected that there was no possibility of recovering spinal cord function. Complete segmental spinal resection (total en bloc spondylectomy) was performed. At that level, the spinal cord was also cut and resected.
Results: En bloc excision of the tumor with a wide margin was achieved in both cases. In the resected specimen, the nerve cells in the spinal cord had lapsed into degenerative necrosis. The pathologic findings showed that there was no hope for recovery of spinal cord function.
Conclusion: En bloc spinal resection, including the spinal cord, is an operation allowed when there is no hope for recovery of spinal cord function. This surgery should be accepted as an option in spine tumor surgeries.

Hypertrophic pachymeningitis (HP) is a rare inflammatory disease that causes the thickening of the dura mater. Its etiology is mainly classified as idiopathic or secondary, and autoimmune disease is one of the main causes of secondary HP. Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis and IgG4-related disease are common among autoimmune diseases.

Spinal microglia and astrocytes are both involved in neuropathic and inflammatory pain, which may display sexual dimorphism. Here, we demonstrate that the sustained activation of spinal astrocytes and astrocyte-derived interleukin (IL)-17A promotes the progression of mouse bone cancer pain without sex differences. Chemogenetic or pharmacological inhibition of spinal astrocytes effectively ameliorates bone cancer-induced pain-like behaviors.

Background: Spinal cord injury (SCI) triggers a complex inflammatory response that impedes neural repair and functional recovery. The modulation of macrophage phenotypes is thus considered a promising therapeutic strategy to mitigate inflammation and promote regeneration.
Methods: We employed microarray and single-cell RNA sequencing (scRNA-seq) to investigate gene expression changes and immune cell dynamics in mice following crush injury at 3 and 7 days post-injury (dpi).

Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is a rare white matter disease characterized by axonal and glial injury. Although its clinical characteristics have been described in case reports, the prevalence of CSF1R mutations in clinically suspected ALSP cases remains unclear. Herein, we analysed the frequency of CSF1R mutations in patients with probable or possible ALSP and describe the genetic, clinical, radiological, and pathological findings of ALSP cases in individuals of Korean ancestry.

Spinal cord injury (SCI) poses a complex set of physiological, psychological, and cognitive challenges that significantly affect an individual's quality of life. Analysis of longitudinal studies reveals that cognitive changes following SCI are often underestimated yet significantly impact patient's ability to adapt to their new circumstances. However, the role of neuropsychology in SCI management and rehabilitation is yet to be elucidated.
