Thoracic VGluT2 Spinal Interneurons Regulate Structural and Functional Plasticity of Sympathetic Networks after High-Level Spinal Cord Injury.

J Neurosci 2022 04 18;42(17):3659-3675. Epub 2022 Mar 18.

Department of Neuroscience, Center for Brain and Spinal Cord Repair, Belford Center for Spinal Cord Injury, Wexner Medical Center, The Ohio State University, Columbus, Ohio 43210

Traumatic spinal cord injury (SCI) above the major spinal sympathetic outflow (T6 level) disinhibits sympathetic neurons from supraspinal control, causing systems-wide "dysautonomia." We recently showed that remarkable structural remodeling and plasticity occurs within spinal sympathetic circuitry, creating abnormal sympathetic reflexes that exacerbate dysautonomia over time. As an example, thoracic VGluT2 spinal interneurons (SpINs) become structurally and functionally integrated with neurons that comprise the spinal-splenic sympathetic network and immunological dysfunction becomes progressively worse after SCI.

Role of Descending Serotonergic Fibers in the Development of Pathophysiology after Spinal Cord Injury (SCI): Contribution to Chronic Pain, Spasticity, and Autonomic Dysreflexia.

Biology (Basel) 2022 Feb 1;11(2). Epub 2022 Feb 1.

Department of Psychological and Brain Sciences, Texas A&M University, College Station, TX 77843, USA.

As the nervous system develops, nerve fibers from the brain form descending tracts that regulate the execution of motor behavior within the spinal cord, incoming sensory signals, and capacity to change (plasticity). How these fibers affect function depends upon the transmitter released, the receptor system engaged, and the pattern of neural innervation. The current review focuses upon the neurotransmitter serotonin (5-HT) and its capacity to dampen (inhibit) neural excitation. Read More

Autonomic Dysreflexia After Hip Fractures Managed by Regional Anesthesia: A Case Report.

A A Pract 2022 Jan 11;16(1):e01556. Epub 2022 Jan 11.

Department of Anesthesiology, Sidney Kimmel Medical College at Thomas Jefferson University, Philadelphia, Pennsylvania.

Autonomic dysreflexia occurs after a spinal cord injury usually at the level of T6 or above, and its hallmark feature is exaggerated autonomic response to noxious stimuli resulting in uncontrolled hypertensive episodes with reflexive bradycardia that can be fatal if not controlled. We present a case highlighting regional anesthetic techniques, including peripheral nerve blocks, to ameliorate the symptoms of autonomic dysreflexia triggered by hip fractures in a 57-year-old woman with an old C5-C6 spinal cord injury before definitive hip surgery. The regional techniques described provide anesthesiologists with a simple strategy to potentially mitigate a life-threatening situation. Read More

Diagnostic and Therapeutic Particularities in Abdominal Trauma Associated with Spinal Cord Injuries - Review of the Literature.

Chirurgia (Bucur) 2021 Dec;116(6):669-677

Post-traumatic morbid associations may evolve by themselves, or can interact, with effects of adding or potentiating gravity. Sometimes cumulative or potentiating effects are associated with clinical and paraclinical confusing manifestations induced by one of the components of the lesion complex, or by mutually aggravating effects. It is also the case of vertebromedular traumas associated with other post-traumatic lesions, where the neurological signal is distorted, and may induce particularities of associated lesions.

Peripherally delivered Adeno-associated viral vectors for spinal cord injury repair.

Exp Neurol 2022 02 8;348:113945. Epub 2021 Dec 8.

Neurorestoration Group, Wolfson Centre for Age-Related Diseases, King's College London, University of London, 16-20 Newcomen Street, London SE1 1UL, United Kingdom. Electronic address:

Via the peripheral and autonomic nervous systems, the spinal cord directly or indirectly connects reciprocally with many body systems (muscular, intengumentary, respiratory, immune, digestive, excretory, reproductive, cardiovascular, etc). Accordingly, spinal cord injury (SCI) can result in catastrophe for multiple body systems including muscle paralysis affecting movement and loss of normal sensation, as well as neuropathic pain, spasticity, reduced fertility and autonomic dysreflexia. Treatments and cure for an injured spinal cord will likely require access of therapeutic agents across the blood-CNS (central nervous system) barrier. Read More

Sint Maartenskliniek, afd. Revalidatiegeneeskunde, Nijmegen.

Depending on the level and severity of spinal cord injury (SCI), SCI patients may suffer from loss of autonomic nervous system function besides the well-known motor and sensory function loss. Changes in the autonomic control of the cardiovascular system can lead to the life-threatening phenomenon of autonomic dysreflexia (AD), especially in patients with cervical or high thoracic SCI. AD is defined as a sudden increase in systolic blood pressure of at least 20 mmHg above baseline. Read More

Auton Neurosci 2022 01 11;237:102905. Epub 2021 Nov 11.

Spaulding Rehabilitation Hospital, 300 First Ave, Boston, MA 02129, USA; Department of Physical Medicine & Rehabilitation, Harvard Medical School, 300 First Ave, Boston, MA 02129, USA; Spaulding Research Institute, 300 First Ave, Boston, MA 02129, USA. Electronic address:

High-level spinal cord injury commonly leads to blood pressure instability. This manifests clinically as orthostatic hypotension (OH), where blood pressure can drop to the point of loss of consciousness, and autonomic dysreflexia (AD), where systolic blood pressure can climb to over 300 mmHg in response to an unperceived noxious stimulus. These blood pressure fluctuations can occur multiple times a day, contributing to increased vessel shear stress and heightened risk of cardiovascular disease. Read More
