Background Accumulating evidence on the causal role of spinal cord microglia activation in the development of neuropathic pain after peripheral nerve injury suggests that microglial activation inhibitors might be useful analgesics for neuropathic pain. Studies also have shown that polyamidoamine dendrimer may function as a drug delivery vehicle to microglia in the central nervous system. In this regard, we developed polyamidoamine dendrimer-conjugated triamcinolone acetonide, a previously identified microglial activation inhibitor, and tested its analgesic efficacy in a mouse peripheral nerve injury model...

Background L-acetylcarnitine, a drug marketed for the treatment of chronic pain, causes analgesia by epigenetically up-regulating type-2 metabotropic glutamate (mGlu2) receptors in the spinal cord. Because the epigenetic mechanisms are typically long-lasting, we hypothesized that analgesia could outlast the duration of L-acetylcarnitine treatment in models of inflammatory and neuropathic pain. Results A seven-day treatment with L-acetylcarnitine (100 mg/kg, once a day, i.p.) produced an antiallodynic effect in the complete Freund adjuvant mouse model of chronic inflammatory pain...

Neuropathic pain is a major complication of spinal cord injury, and despite aggressive efforts, this type of pain is refractory to available clinical treatment. Our previous work has demonstrated a structure-function link between dendritic spine dysgenesis on nociceptive sensory neurons in the intermediate zone, laminae IV/V, and chronic pain in central nervous system and peripheral nervous system injury models of neuropathic pain. To extend these findings, we performed a follow-up structural analysis to assess whether dendritic spine remodeling occurs on superficial dorsal horn neurons located in lamina II after spinal cord injury...

Pregabalin is often used for the treatment of neuropathic pain in patients with spinal cord injury (SCI). We reported a patient with C5 [S(C5/C6)] ASIA Impairment Scale C SCI due to cervical myelopathy who presented CO2 retention when taking a therapeutic dosage of pregabalin. An 88-year-old patient with cervical SCI was transferred to the department of physical medicine and rehabilitation. When he had transferred, his neuropathic pain had been treated with 150-mg pregabalin per day (75 mg twice a day); however, he still exhibited severe neuropathic pain with a Numeric Pain Rating Scale score of 7 to 8...

Stem cells from human exfoliated deciduous teeth (SHED) transplants have been investigated as a possible treatment strategy for spinal cord injuries (SCI) due to their potential for promoting functional recovery. The aim of present study was to investigate the effects of SHED on neuronal death after an experimental model of SCI. METHODS: Wistar rats were spinalized using NYU impactor®. Animals were randomly distributed into 4 groups: Control (Naive) or Surgical control, Sham (laminectomy with no SCI); SCI (laminectomy followed by SCI, treated with vehicle); SHED (SCI treated with intraspinal transplantation of 3×10(5) SHED, 1 h after SCI)...

STUDY DESIGN: Retrospective statistical analysis of database. OBJECTIVE: Spinal cord injury (SCI) clinical trials are challenged to enroll participants, and early trial outcomes have often been equivocal. We hypothesized that a specifically designed novel true linear interval-scaled outcome measure targeted to simultaneously track a broad range of SCI will enable more inclusive enrollment of participants and valid comparisons of functional changes after SCI. METHODS: To define a single SCI measurement framework, we used items from existing measures...

We investigated the effect of progesterone (P4) treatment on diabetes/hyperglycemia-induced pathological changes in brain, spinal cord and sciatic nerve tissue in male rats. Animals were rendered hyperglycemic by a single dose of streptozotocin (STZ). P4 treatment was started after hyperglycemia was confirmed and body weight and blood glucose levels were monitored once/week for 5 weeks. Rats underwent behavioral testing at week 5 and were then euthanized for histology. We assessed the expression of markers of angiogenesis (vascular endothelial growth factor (VEGF)), inflammation (interleukin-6 (IL-6)) and tissue injury (CD11b, NG2, COX2 and matrix metalloproteinase-2 (MMP-2)) in the brain, spinal cord and sciatic nerve...

There is a critical need for new analgesics acting through new mechanisms of action, which could increase the efficacy with respect to existing therapies and reduce their unwanted effects. Current preclinical evidence supports the modulatory role of sigma-1 receptors (σ1R) in nociception, mainly based on the pain-attenuated phenotype of σ1R knockout mice and on the antinociceptive effect exerted by σ1R antagonists on pains of different etiologies. σ1R is highly expressed in different pain areas of the CNS and the periphery (particularly dorsal root ganglia), and interacts and modulates the functionality of different receptors and ion channels ...

BACKGROUND: Most patients with spinal cord injury (SCI) suffer from neurogenic lower urinary tract dysfunction (NLUTD), bowel dysfunction and sexual dysfunction. If these remain untreated, severe medical complications and serious limitations (restrictions) in quality of life are imminent. OBJECTIVES: In the long term, there are considerable differences in the treatment results of highly specialized centers versus other treatment facilities. MATERIALS AND METHODS: Against this background, a consensus-based guideline, according to the AWMF (Association of the Scientific Medical Societies in Germany) criteria (S2k), was developed by the neuro-urology working group of the DMPG (German-Speaking Medical Society of Paraplegia)...

Spinal cord stimulation (SCS) is used to treat neuropathic pain, but there are no published studies on its use to treat burn pain. We used SCS to treat a 67-year-old man suffering from burn pain that could not be managed with high-dose opioids or adjuvant neuropathic analgesics. A trial of SCS markedly reduced the visual analog scale score for pain in the left lateral abdominal and gluteal regions. He underwent permanent implantation of a SCS and achieved an opioid-free state. This case suggests that SCS treatment is a therapeutic option for burn pain refractory to conventional therapy...

Spinal cord injury (SCI) is a devastating condition, where regenerative failure and cell loss lead to paralysis. The heterogeneous and time-sensitive pathophysiology has made it difficult to target tissue repair. Despite many medical advances, there are no effective regenerative therapies. As stem cells offer multi-targeted and environmentally responsive benefits, cell therapy is a promising treatment approach. Areas covered: This review highlights the cell therapies being investigated for SCI, including Schwann cells, olfactory ensheathing cells, mensenchymal stem/stromal cells, neural precursors, oligodendrocyte progenitors, embryonic stem cells, and induced pluripotent stem cells...

OBJECTIVE Posterior atlantoaxial stabilization and fusion using C-1 lateral mass screw fixation has become commonly used in the treatment of instability and for reconstructive indications since its introduction by Goel and Laheri in 1994 and modification by Harms in 2001. Placement of such lateral mass screws can be challenging because of the proximity to the spinal cord, vertebral artery, an extensive venous plexus, and the C-2 nerve root, which overlies the designated starting point on the posterior center of the lateral mass...

OBJECTIVE In patients with cervical spondylotic myelopathy (CSM), the motor system may undergo progressive functional/structural changes rostral to the lesion, and these changes may be associated with clinical disability. The extent to which these changes have a prognostic value in the clinical recovery after surgical treatment is not yet known. In this study, magnetic resonance spectroscopy (MRS) was used to test 2 primary hypotheses. 1) Based on evidence of corticospinal and spinocerebellar, rubro-, or reticulospinal tract degeneration/dysfunction during chronic spinal cord compression, the authors hypothesized that the metabolic profile of the primary motor cortices (M1s) and cerebellum, respectively, would be altered in patients with CSM, and these alterations would be associated with the extent of the neurological disabilities...

PURPOSE: Spinal Cord injury represents, in veterinary medicine, most of the neurological attendances and may result in permanent disability, death or euthanasia. Due to inflammation resulting from trauma, it originates the glial scar, which is a cell interaction complex system. Its function is to preserve the healthy circuits, however, it creates a physical and molecular barrier that prevents cell migration and restricts the neuroregeneration ability. METHODS: This review aims to present innovations in the scene of treatment of spinal cord injury, approaching cell therapy, administration of enzyme, anti-inflammatory, and other active principles capable of modulating the inflammatory response, resulting in glial scar reduction and subsequent functional improvement of animals...
