Spinal cord

Sarah Löw, Tracy T Batchelor
Primary central nervous system lymphoma (PCNSL) is an extranodal non-Hodgkin lymphoma limited to the brain, spinal cord, leptomeninges, and eyes. The majority of patients are immunocompetent, with a median age of 65 years at diagnosis. Historically, whole-brain radiation therapy (WBRT) was the first and sole treatment for PCNSL. Today, due to the recognized neurotoxicity of WBRT, this modality is usually avoided in the treatment. Most chemotherapy regimens are based on high-dose methotrexate plus the anti-CD20 monoclonal antibody rituximab, leading to high response rates, but 5-year survival is still poor at approximately 30% compared with other extranodal lymphomas...

BACKGROUND: Advanced cervical spondylosis (CS) can cause structural damage to the spinal cord resulting in long-term neurological impairment including neck pain and motor weakness. We hypothesized long-term structural reorganization within the brain in patients with CS. OBJECTIVE: To explore the associations between cortical thickness, subcortical volumes, neurological symptoms, and pain severity in CS patients with or without myelopathy and healthy controls (HCs)...

BACKGROUND: Spinal cord stimulation (SCS) is a common intervention for managing intractable pain. Generally, leads are implanted in a minimally invasive procedure with verbal feedback regarding the location and nature of generated paresthesias by active stimulation; in this way their optimal location can be confirmed. However, lead placement under general anesthesia can have additional benefits. OBJECTIVE: To investigate the outcomes of awake vs asleep lead placement procedures...

: Individuals with concomitant spinal cord injury and traumatic brain injury have cognitive deficits that may limit the ability to learn novel motor tasks necessary for functional independence. Errorless learning has been shown to improve cognitive task performance in persons with brain injury but little is known about its usefulness for improving novel motor task learning. CASE DESCRIPTION: A 44-year-old man with traumatic spinal cord and brain injuries from a motor vehicle accident was admitted to an inpatient rehabilitation hospital...

BACKGROUND AND PURPOSE: Previous data suggest that large amounts of high-intensity stepping training in variable contexts (tasks and environments) may improve locomotor function, aerobic capacity, and treadmill gait kinematics in individuals poststroke. Whether similar training strategies are tolerated and efficacious for patients with other acute-onset neurological diagnoses, such as motor incomplete spinal cord injury (iSCI), is unknown. Individuals with iSCI potentially have greater bilateral impairments...

BACKGROUND: Neuropathic pain is one of the common complications after spinal cord injury (SCI), affecting patients' life quality. The molecular mechanism for neuropathic pain after SCI is still unclear. We aimed to discover potential genes and MicroRNAs(miRNAs) related to neuropathic pain by bioinformatics method. METHODS: Microarray data of GSE69901 were obtained from Gene Expression Omnibus (GEO) database. Peripheral blood samples from patients with or without neuropathic pain after spinal cord injury (SCI) were collected...

Symptomatic ventral cervical cord compressions have been treated by anterior discectomy with fusion, anterior corpectomy and fusion, discectomy with an artificial disc, and minimally invasive techniques. There are complications associated with the fusion procedure, especially when a long segment fusion is undertaken. Partial removal of the vertebral body without fusion could help in avoiding fusion and its associated complications. We are describing the detailed surgical technique, indications, limitations, and early results of endoscopic partially corpectomy...

Introduction Neuropathic pain is a debilitating condition. The importance of neuroimmune interactions in neuropathic pain has been evidenced by the involvement of different immune cells in peripheral and central sensitization of pathological pain. Macrophages and microglia are the most abundant immune cells activated in injured nerves and spinal cord, respectively. Several lines of evidence showed that macrophage/microglia survival, activation, proliferation, and differentiation require the involvement of macrophage-colony stimulating factor...

Cell transplant-mediated tissue repair of the damaged spinal cord is being tested in several clinical trials. The current candidates are neural stem cells, stromal cells, and autologous Schwann cells (aSC). Due to their peripheral origin and limited penetration of astrocytic regions, aSC are transplanted intralesionally as compared to neural stem cells that are transplanted into intact spinal cord. Injections into either location can cause iatrogenic injury, and thus technical precision is important in the therapeutic risk-benefit equation...

Adult Schwann cells (SCs) can provide both a permissive substrate for axonal growth and a source of cells to ensheath and myelinate axons when transplanted into the injured spinal cord. Multiple studies have demonstrated that SC transplants can be used as part of a combinatorial approach to repairing the injured spinal cord. Here, we describe the protocols for collection and transplantation of adult rat primary SCs into the injured spinal cord. Protocols are included for the tissue culture procedures necessary for collection, quantification, and suspension of the cells for transplantation and for the surgical procedures for spinal cord injury at thoracic level nine (T9), reexposure of the injury site for delayed transplantation, and injection of the cells into the spinal cord...

In vitro models using Schwann cell and astrocyte co-cultures have been used to understand the mechanisms underlying the formation of boundaries between these cells in vivo. Schwann cell/astrocyte co-cultures also mimic the in vivo scenario of a transplant in a spinal cord injury site, thereby allowing testing of therapeutic approaches. In this chapter, we describe a triple cell culture system with Schwann cells, astrocytes, and neurons that replicates axon growth from a Schwann cell graft into an astrocyte-rich region...

Cell-based therapies have become a major focus in preclinical research that leads to clinical application of a therapeutic product. Since 1990, scientists at the Miami Project to Cure Paralysis have generated extensive data demonstrating that Schwann cell (SC) transplantation supports spinal cord repair in animals with spinal cord injury. After preclinical efforts in SC transplantation strategies, efficient methods for procuring large, essentially pure populations of SCs from the adult peripheral nerve were developed for rodent and pig studies...

Neurosyphilis occurs in the late stage of systemic syphilis infection; early diagnosis and treatment are crucial to the prognosis. We review 3 autopsy cases with different subtypes of neurosyphilis, that is cases with meningovascular, general paresis, and a combination of the 2, respectively. We investigated the gross morphology and leptomeninges, vessels, cerebral cortex, white matter, brainstem, cerebellum, olfactory bulb and spinal cord microscopically. We found that meningovascular inflammation exists in both early and late phases of neurosyphilis, not only in the meningovascular subtype...

The purpose of the present study was to establish an effective robotic assistive stepping pattern of body-weight-supported treadmill training based on a rat spinal cord injury (SCI) model and assess the effect by comparing this with another frequently used assistive stepping pattern. The recorded stepping patterns of both hind limbs of trained intact rats were edited to establish a 30-sec playback normal rat stepping pattern (NRSP). Step features (step length, step height, step number and swing duration), BBB scores, latencies, and amplitudes of the transcranial electrical motor-evoked potentials (tceMEPs) and neurofilament 200 (NF200) expression in the spinal cord lesion area during and after 3 weeks of body-weight-supported treadmill training (BWSTT) were compared in rats with spinal contusion receiving NRSP assistance (NRSPA) and those that received manual assistance (MA)...

[Purpose] Robot-assisted gait training (RAGT) using Hybrid Assistive Limb (HAL, CYBERDYNE) was previously reported beneficial for stroke and spinal cord injury patients. Here, we investigate the immediate effect of a single session of RAGT using HAL on gait function for cerebral palsy (CP) patients. [Subjects and Methods] Twelve patients (average age: 16.2 ± 7.3 years) with CP received a single session of RAGT using HAL. Gait speed, step length, cadence, single-leg support per gait cycle, hip and knee joint angle in stance, and swing phase per gait cycle were assessed before, during, and immediately after HAL intervention...
