BACKGROUND: The objective of this study was to assess the relationship between exposure to methylprednisolone (MP) and improvements in motor function among patients with acute traumatic spinal cord injury (TSCI). MP therapy for patients with TSCI is controversial because of the current conflicting evidence documenting its benefits and risks. METHODS: We conducted a retrospective cohort study from September 2007 to November 2014 of 311 patients with acute TSCI who were enrolled into a model systems database of a regional, level I trauma center...

PURPOSE OF REVIEW: The current review describes the current evidence on pediatric spinal cord injury without radiographic abnormality (SCIWORA) with attention to the definition, epidemiology, and clinical presentation of the condition, as well as common MRI findings, management strategies, and outcomes. RECENT FINDINGS: Recent literature demonstrates that with more widespread MRI use, our understanding of SCIWORA has improved. The new literature, although still limited, provides a more granular conceptualization of patterns of injury as well as potential prognostic stratification of patients based on MRI findings...

Acrolein is one of the most toxic byproducts of lipid peroxidation, and it has been shown to be associated with multiple pathological processes in trauma and diseases, including spinal cord injury, multiple sclerosis, and Alzheimer's disease. Therefore, suppressing acrolein using acrolein scavengers has been suggested as a novel strategy of neuroprotection. In an effort to identify effective acrolein scavengers, we have confirmed that dimercaprol, which possesses thiol functional groups, could bind and trap acrolein...

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...

Teresa G Odle
Thoracolumbar spine trauma typically occurs when high-energy forces damage bony and ligamentous spinal structures and, in severe cases, the spinal cord. These injuries often cause considerable neurological deficits as a result of the damage. Computed tomography (CT) is the imaging method of choice for determining injury severity in most victims of multiple trauma. In addition to describing various types of thoracolumbar trauma, this article discusses the role of CT in emergency diagnosis and management of thoracolumbar injuries...

Functional deficits persist after spinal cord injury (SCI) because axons in the adult mammalian central nervous system (CNS) fail to regenerate. However, modest levels of spontaneous functional recovery are typically observed after trauma and are thought to be mediated by the plasticity of intact circuitry. The mechanisms underlying intact circuit plasticity are not delineated. Here, we characterize the in vivo transcriptome of sprouting intact neurons from Ngr1 null mice after partial SCI. We identify the lysophosphatidic acid signaling modulators LPPR1 and LPAR1 as intrinsic axon growth modulators for intact corticospinal motor neurons after adjacent injury...

OBJECTIVE There has been no established animal model of syringomyelia associated with lumbosacral spinal lipoma. The research on the pathophysiology of syringomyelia has been focused on Chiari malformation, trauma, and inflammation. To understand the pathophysiology of syringomyelia associated with occult spinal dysraphism, a novel animal model of syringomyelia induced by chronic mechanical compression of the lumbar spinal cord was created. METHODS The model was made by epidural injection of highly concentrated paste-like kaolin solution through windows created by partial laminectomy of L-1 and L-5 vertebrae...

INTRODUCTION: Spinal cord infarction followed by minor trauma in pediatric patients is rare and causes serious paralysis. Fibrocartilaginous embolism (FCE) is a possible diagnosis and there have been no consecutive magnetic resonance imaging (MRI) reports. Here, we report a case of an acute complete paraplegia with spinal cord infarction and longitudinal spinal cord signal change following minor trauma in an 8-year-old girl. CASE DESCRIPTION: An 8-year-old girl presented to our hospital emergency services with total paraplegia 2 h after she hit her back and neck after doing a handstand and falling down...

Efforts to validate novel therapies in acute clinical trials for spinal cord injury (SCI) are impeded by the lack of objective quantitative measures that reflect injury severity and accurately predict neurologic recovery. Therefore, a strong rationale exists to establish neurochemical biomarkers that objectively quantify injury severity and predict outcome. Here, we conducted a targeted proteomics analysis of cerebrospinal fluid (CSF) samples derived from 29 acute SCI patients (AIS A, B, or C) acquired at 24, 48, and 72 hours post-injury...

Dorsal root injury is a situation not expected to be followed by a strong regenerative growth, or growth of the injured axon into the central nervous system of the spinal cord, if the central axon of the dorsal root is injured but of strong regeneration if subjected to injury to the peripherally projecting axons. The clinical consequence of axonal injury is loss of sensation and may also lead to neuropathic pain. In this study, we have used in situ hybridization to examine the distribution of mRNAs for the neural guidance molecules semaphorin 3A (SEMA3A), semaphorin 3F (SEMA3F), and semaphorin 4F (SEMA4F), their receptors neuropilin 1 (NP1) and neuropilin 2 (NP2) but also for the neuropilin ligand vascular endothelial growth factor (VEGF) and Tenascin J1, an extracellular matrix molecule involved in axonal guidance, in rat dorsal root ganglia (DRG) after a unilateral dorsal rhizotomy (DRT) or sciatic nerve transcetion (SNT)...

Injuries to peripheral nerves are frequent in serious traumas and spinal cord injuries. In addition to surgical approaches, other interventions, such as cell transplantation, should be considered to keep the muscles in good condition until the axons regenerate. In this study, E14.5 rat embryonic spinal cord fetal cells and cultured neural progenitor cells from different spinal cord segments were injected into transected musculocutaneous nerve of 200-300 g female Sprague Dawley (SD) rats, and atrophy in biceps brachii was assessed...

INTRODUCTION: Spinal epidural hematoma (SEH) is a rare disease that causes cord compression and neurologic deficit. Spontaneous SEH is related to minor trauma, bleeding disorders, and anticoagulant medications. Posttraumatic SEH has been associated with low-energy spine hyperextension injuries in patients with ankylosing spinal disorders such as ankylosing spondylitis and diffuse idiopathic skeletal hyperostosis (DISH). A variant named atypical DISH-like with SEH is reported. OBJECTIVE: To describe the management, diagnosis, and treatment of an unusual SEH case in a patient causing delayed neurologic deficit with rigid atypical DISH-like spine...

Spinal cord injury (SCI) is a severe trauma for which no effective treatment is currently available. In this study, a composited treatment system was prepared using a silk fibroin/alginates/glial cell line-derived neurotrophic factor (SF/AGs/GDNF) scaffold seeded with human umbilical cord mesenchymal stem cells (hUCMSCs) and the combined therapeutic effects of the composite scaffold to repair SCI rats were evaluated. The use of SF as a scaffold material could act as a biomimetic platform allowing neurons to properly accommodate and rebuild the target tissue...

BACKGROUND: The ability of diffusion tensor imaging (DTI) to complement conventional MR imaging by diagnosing subtle injuries to the spinal cord is a subject of intense research. We attempted to study change in the DTI indices, namely fractional anisotropy (FA) and mean diffusivity (MD) after traumatic cervical spinal cord injury and compared these with corresponding data from a control group of individuals with no injury. The correlation of these quantitative indices to the neurological profile of the patients was assessed...

The rationale for implantation of autologous human Schwann cells (SCs) in persons with subacute spinal cord injury (SCI) is based on evidence that transplanted SCs are neuroprotective, support local axonal plasticity, and are capable of myelinating axons. A Phase I clinical trial was conducted to evaluate the safety of autologous human SC transplantation into the injury epicenter of six subjects with subacute SCI. The trial was an open-label, unblinded, non-randomized, non-placebo controlled study with a dose escalation design and standard medical rehabilitation...
