The differential pharmacological responsiveness of cephalic and extra-cephalic neuropathic pain has been proposed to relate to distinct mechanisms that may involve neuroinflammatory reactions mediated by glial cells. Astrocytes are particularly important for neuronal sensitization in neuropathic pain, in part through modulation of glutamatergic transmission. Because the metabotropic glutamate receptor 5 (mGluR5) is involved in the astrocytic regulation of the glutamatergic system, we investigated modifications of its expression in models of cephalic versus extra-cephalic neuropathic pain...

Telehealth refers to health care interactions that leverage telecommunication devices to provide medical care outside the traditional face-to-face, in-person medical encounter. Technology advances and research have expanded use of telehealth in health care delivery. Physical medicine and rehabilitation providers may use telehealth to deliver care to populations with neurologic and musculoskeletal conditions, commonly treated in both acute care and outpatient settings. Patients with impaired mobility and those living in locations with reduced access to care may particularly benefit...

Agmatine is a neuromodulator that regulates multiple neurotransmitters and signaling pathways. Several studies have focused on elucidating the mechanisms underlying the neuroprotective effects of this molecule, which seems to be mediated by a reduction in oxidative damage, neuroinflammation, and proapoptotic signaling. Since these events are implicated in acute and chronic excitotoxicity-related disorders (ischemia, epilepsy, traumatic brain injury, spinal cord injury, neurodegenerative, and psychiatric disorders) as well as in nociception, agmatine has been proposed as a therapeutic strategy for the treatment of central nervous system (CNS) disorders...

Open spina bifida or myelomeningocele (MMC) is one of the most common serious congenital malformations. Historically, this condition has been treated with closure of the MMC defect shortly after birth. The goal of postnatal closure is to cover the exposed spinal cord and prevent infection. However, postnatal surgery does not reverse or prevent the neurologic injury seen in MMC, reverse hindbrain herniation, or prevent hydrocephalus. The neurologic defects result from primary incomplete neurulation and secondary chronic prenatal damage to the exposed neural elements through mechanical and chemical trauma...

Schwann cells (SCs) are promising candidates for transplantation-strategies in the central nervous system by promoting axonal regeneration. The dog represents a translational model for human spinal cord injury (SCI) for studies with new repair strategies after intervertebral disk herniation (IVDH). To overcome the necessity for an additional surgical procedure, for the first time a protocol for isolation, and purification of canine SCs from spinal-nerve-biopsies during standard hemilaminectomy in IVDH affected paraplegic dogs for potential transplantation was developed...

BACKGROUND: Recovering hand function has important implications for improving independence of patients with tetraplegia after traumatic spinal cord injury (SCI). Transcranial direct current stimulation (tDCS) is a noninvasive rehabilitation technique that has potential to improve motor function. OBJECTIVE: To investigate the effects of one session of 1 mA, 2 mA, and sham anodal tDCS (a-tDCS) in the upper extremity (hand) motor performance (grasp and lease) in patients with chronic cervical SCI...

Pathological conditions such as amyotrophic lateral sclerosis, spinal cord injury and chronic pain are characterized by activation of astrocytes and microglia in spinal cord and have been modeled in rodents. In vivo imaging at cellular level in these animal models is limited due to the spinal cord's highly myelinated funiculi. The preparation of acute slices may offer an alternative and valuable strategy to collect structural and functional information in vitro from dorsal, lateral and ventral regions of spinal cord...

Neurogenic bladder is common in most spinal cord injury patients. Voiding cystourethrography (VCUG) is recommended in these patients to detect urinary tract complications. However, rare but serious complications may occur during VCUG, although VCUG is generally safe. There are several case reports of bladder rupture occurring in pediatric patients. Here, we report the first case of iatrogenic bladder rupture in an adult spinal cord injury patient in Korea. Particularly, extravasation of contrast without manual instillation has hardly ever been reported...

Spinal Cord Injury (SCI) is a serious devastating condition associated to the high chances of morbidity and mortality. It involves a primary and a secondary injury, former cause damages to both lower and upper motor neurones and disrupts sensory, motor and autonomic functions while the latter involves various stages of molecular plus cellular incidents which elaborate the original injury. In the treatment of SCI, stem cells possess a good therapeutic potential. Bone marrow, adipose tissue, placenta, amniotic fluid and umbilical cord are the good sources for mesenchymal stem cells...

PURPOSE: Spinal cord injury (SCI) results in accelerated bone mineral density (BMD) loss and disorganization of trabecular bone architecture. The mechanisms underlying post-SCI osteoporosis are complex and different from other types of osteoporosis. Findings of studies investigating efficacy of pharmacological or rehabilitative interventions in SCI-related osteoporosis are controversial. The aim of this study was to review the literature pertaining to prevention and evidence-based treatments of SCI-related osteoporosis...

BACKGROUND: CNS inflammation resulting from infection, injury, or neurodegeneration leads to accumulation of diverse B cell subsets. Although antibody secreting cells (ASC) within the inflamed CNS have been extensively examined, memory B cell (Bmem) characterization has been limited as they do not secrete antibody without stimulation. Moreover, unlike human Bmem, reliable surface markers for murine Bmem remain elusive. NEW METHOD: Using a viral encephalomyelitis model we developed a modified limiting dilution in vitro stimulation assay to convert CNS-derived virus specific Bmem into ASC...

CONTEXT: There are few treatment options for managing autonomic dysreflexia in patients with chronic spinal cord injury (SCI). According to some studies, intravesical botulinum toxin for SCI patients with autonomic dysreflexia has a preventive effect on symptoms of autonomic dysreflexia. However, the usefulness of an intravesical botulinum toxin injection has never been reported for autonomic dysreflexia in an adult patient with chronic cervical SCI, although there has been for one pediatric patient...

Effective therapeutic strategies for treating chronic spinal cord injury (SCI) are currently unavailable. Scar tissue in the lesion area is a main inhibitory factor for axonal regeneration and repair of chronic SCI. In this study, scar tissue was surgically resected from adult rats with 12-week chronic SCI, and then collagen scaffold (named NeuroRegen Scaffold [NRS]) and human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) were implanted into the resected cavity to repair chronic SCI. The results demonstrated that the locomotor function of rats was not affected by surgical scar resection, indicating its safety in treating chronic SCI...

Recovery of lower-limb function after spinal cord injury (SCI) likely depends on transmission in the corticospinal pathway. Here, we examined whether paired corticospinal-motoneuronal stimulation (PCMS) changes transmission at spinal synapses of lower-limb motoneurons in humans with chronic incomplete SCI and aged-matched controls. We used 200 pairs of stimuli where corticospinal volleys evoked by transcranial magnetic stimulation (TMS) over the leg representation of the motor cortex were timed to arrive at corticospinal-motoneuronal synapses of the tibialis anterior (TA) muscle 2 ms before antidromic potentials evoked in motoneurons by electrical stimulation of the common peroneal nerve (PCMS+) or when antidromic potentials arrived 15 or 28 ms before corticospinal volleys (PCMS-) on separate days...

Human functional MRI studies in acute and various chronic pain conditions have revolutionized how we view pain, and have led to a new theory that complex multi-dimensional pain experience (sensory-discriminative, affective/motivational, and cognitive) is represented by concurrent activity in widely-distributed brain regions (termed a network or pain matrix). Despite these breakthrough discoveries, the specific functions proposed for these regions remain elusive, because detailed electrophysiological characterizations of these regions in the primate brain are lacking...

Chronic spinal cord injury (SCI) is often associated with reductions in left ventricular (LV) diastolic function. Impairments in sympathetic activity and activation of the renin-angiotensin system are reported in SCI individuals and may hypothetically be implicated in this association. Hence, the present study verified the relationship between these two neuro-hormonal and cardiac functional and structural characteristics in SCI individuals. Twenty-two men with SCI (injury level above T6 and no voluntary motion below the injury) and 11 able-bodied men were evaluated by clinical, hemodynamic, laboratory and echocardiographic analysis, and had plasmatic renin, angiotensin I (ANGI), angiotensin II (ANGII), angiotensin 1-7 (ANG1-7) and noradrenaline levels measured...

Objective Age and lesion level are believed to represent outcome predictors in rehabilitation of patients with chronic spinal cord injury (SCI). The Hybrid Assistive Limb (HAL) exoskeleton enables patients to perform a voluntary controlled gait pattern via an electromyography-triggered neuromuscular feedback system, and has been introduced as a temporary gait training tool in patients with SCI. The aim of this prospective pre- and postintervention study was to examine functional outcomes as a function of age and lesion level in patients with chronic incomplete SCI (iSCI) or chronic complete SCI (cSCI) with zones of partial preservation (ZPP) by using the HAL as a temporary training tool...
