The rationale for implantation of autologous human Schwann cells (SCs) in people 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...

BACKGROUND: and Purpose: Several studies have looked for an association between radiological findings and neurological outcome after cervical trauma. In the current literature, there is a paucity of evidence proving the prognostic role of soft tissue damage or bony integrity. Our objective is to determine radiological findings related to neurological prognosis in patients after incomplete acute traumatic cervical spinal cord injury, regardless of initial neurological exam. MATERIAL AND METHODS: We retrospectively reviewed patients with acute traumatic cervical Spinal Cord Injury who had an MRI performed within the first 96 hours...

Spinal cord injury (SCI) is a clinical syndrome encountered frequently in trauma centers and is accompanied by both acute and chronic heart rhythm abnormalities. The injury is characterized by sympathetic nervous system (SNS) impairment with preservation of parasympathetic output via the vagus nerve. Severe bradycardia in the form of life-threatening sinus arrest or complete heart block may be observed in the acute recovery phase. Therapy for arrhythmias in the acute phase includes atropine, intravenous chronotropes, methylxanthines for prevention of episodic bradycardia, and pacemaker implantation in severe cases...

Neuronal cell death following spinal cord injury (SCI) is an important contributor to neurological deficits. The purpose of our work was to delineate the function of mammalian sterile 20-like kinase 1 (Mst1), a pro-apoptotic kinase and key mediator of apoptotic signaling, in the pathogenesis of an experimental mouse model of SCI. Male mice received a mid-thoracic spinal contusion injury, and it was found that phosphorylation of Mst1 at the injured site was enhanced significantly following SCI. Furthermore, when compared to the wild-type controls, Mst1-deficient mice displayed improved locomotor function by increased Basso mouse scale score...

Neurologic complications in polytrauma can be classified by etiology and clinical manifestations: neurovascular, delirium, and spinal or neuromuscular problems. Neurovascular complications include ischemic strokes, intracranial hemorrhage, or the development of traumatic arteriovenous fistulae. Delirium and encephalopathy have a reported incidence of 67-92% in mechanically ventilated polytrauma patients. Causes include sedation, analgesia/pain, medications, sleep deprivation, postoperative state, toxic ingestions, withdrawal syndromes, organ system dysfunction, electrolyte/metabolic abnormalities, and infections...

After unresolved endoplasmic reticulum stress, recovery of protein synthesis including increased expression of ribosomal components and translation factors may induce cell death. Using a mouse model of moderate contusive spinal cord injury (SCI) at the T9 level, upregulation of ribosomal biogenesis was observed in the injury epicenter at 24h after trauma. Such upregulation coincided with endoplasmic reticulum stress response as previously reported in this model. It was also accompanied by changes in expression of many other genes associated with translational regulation...

Most spinal cord injury is seen with trauma. Nontraumatic spinal cord emergencies are discussed in this chapter. These myelopathies are rare but potentially devastating neurologic disorders. In some situations prior comorbidity (e.g., advanced cancer) provides a clue, but in others (e.g., autoimmune myelopathies) it may come with little warning. Neurologic examination helps distinguish spinal cord emergencies from peripheral nervous system emergencies (e.g., Guillain-Barré), although some features overlap...

Acute traumatic spinal cord injury (SCI) is a devastating disease process affecting tens of thousands of people across the USA each year. Despite the increase in primary prevention measures, such as educational programs, motor vehicle speed limits, automobile running lights, and safety technology that includes automobile passive restraint systems and airbags, SCIs continue to carry substantial permanent morbidity and mortality. Medical measures implemented following the initial injury are designed to limit secondary insult to the spinal cord and to stabilize the spinal column in an attempt to decrease devastating sequelae...

Spinal trauma is a devastating event with a high morbidity and mortality. The rationale of imaging is to diagnose the traumatic abnormalities and characterize the type of injury, to estimate the severity of the lesions, to evaluate the potential spinal instability. In case of spinal instability, the goals of operative treatment are decompression of the spinal cord canal and stabilization of the disrupted vertebral column. Particularly, diagnostic imaging, mainly by CT and MR, has a main role in the post-treatment evaluation...

In food animals, spinal cord damage is most commonly associated with infection or trauma. Antemortem diagnosis is based on clinical signs, history, cerebrospinal fluid analysis, and imaging. As clinical signs are often severe, and prognosis is grave, necropsy may provide a postmortem diagnosis. Peripheral nerve abnormalities are most often the result of trauma. Calving paralysis or paresis is the most common condition affecting the sciatic or obturator nerve and often concurrently involves the peroneal branch of the sciatic...

BACKGROUND: One of the most severe conditions specific to the critically ill polytrauma patient is traumatic brain injury and traumatic spinal cord injury. The mortality rate is high in the case of these patients, both because of the direct traumatic lesions, and because of the pathophysiological imbalances associated with trauma. Amongst the most common pathologies associated with the critically ill polytrauma patients responsible for a lower survival rate, are redox imbalance, systemic inflammatory response, infections, and multiple organ dysfunction syndrome...

Traumatic spinal cord injury requires a multidisciplinary approach both for specialized treatment of the acute phase and for dealing with the secondary complications. A suspicion or diagnosis of spinal cord injury is the first step for a correct management. A review is made of the prehospital management and characteristics of the acute phase of spinal cord injury. Respiratory monitoring for early selective intubation, proper identification and treatment of neurogenic shock are essential for the prevention of secondary spinal cord injury...

Disease or trauma-induced loss or dysfunction of neurons in any central nervous system (CNS) tissue will have a significant impact on the health of the affected patient. The retina is a multilayered tissue that originates from the neuroectoderm, much like the brain and spinal cord. While sight is not required for life, neurodegeneration-related loss of vision not only affects the quality of life for the patient, but also has societal implications in terms of health care expenditure. Thus, it is essential to develop effective strategies to repair the retina and prevent disease symptoms...

: Introduction Earthquake-related trauma results in crush injuries and bony- and soft-tissue trauma. There are no systematic reviews analyzing the typical injury patterns and treatments in "Mega-Mass-Casualty" earthquakes. The characterization of an injury pattern specific to disaster type, be it natural or manmade, is imperative to build an effective disaster preparedness and response system. METHODS: The systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)...

Spinal cord injury (SCI) is a devastating condition that affects patient on a personal as well as on a societal level. The objective of the study is to improve the prediction of long-term functional outcome following SCI based on the acute clinical findings. 76 patients with acute traumatic SCI were prospectively enrolled in a cohort study in a single level I trauma center. Spinal Cord Independence Measure (SCIM) at 1 year after the trauma was the primary outcome. Potential predictors of functional outcome were recorded during the acute hospitalization: age, sex, level and type of injury, comorbidities, American Spinal Injury Association (ASIA) Impairment Scale (AIS), ASIA Motor Score (AMS), ASIA Light Touch score (LT), ASIA Pin Prick score (PP), Injury Severity Score (ISS), Traumatic Brain Injury (TBI) and delay from trauma to surgery...
