RATIONALE: Patients with Klippel-Feil syndrome (KFS) are always anomaly associated with vertebrobasilar dysplasia. That may present commonly as infarction of brainstem, medulla, and cerebellum. In this article, we reported a rare case of lateral medullary infarction (LMI) with similar features of Brown Sequard syndrome caused by vertebrobasilar dysplasia and KFS, and the 2 rare conditions that are causally related. The case is being reported because of its unusual and rare presentation...

We report the case of a 4-year-old female with a primary extradural intramedullary atypical teratoid/rhabdoid tumor (AT/RT) leading to a middle cerebral artery (MCA) infarct and Froin's syndrome. She presented with a 6-pound weight loss over the previous week, as well as a decreased urinary output and an altered mental status. She underwent a brain MRI that revealed a left MCA infarct, mild ventriculomegaly, and bilateral internal carotid artery, M1, and A1 stenosis. An external ventricular drain (EVD) was placed due to increased intracranial pressure...

Cervical transforaminal epidural steroid injection (TFESI) under the guidance of computed tomography (CT) can offer great anatomical resolution and precise needle placement in the axial plane. However, some complications, including blood pressure surge, allergic reactions, vasovagal syncope, and cerebral infarct, have been reported after CT-guided cervical TFESI. We report the first case of iatrogenic spinal cord injury (SCI) during a CT-guided cervical TFESI. A 67-year-old woman, upon receiving TFESI on Lt...

Among other autonomic dysfunctions complicating acute spinal cord injury, deep hypothermia is rare but may induce serious cardiovascular complications. There are few pharmacological options to influence hypothermia. A 66-year-old woman was transferred to the intensive care unit (ICU) for serious cardiac arrhythmias (atrial fibrillation and asystole) in the context of a deep hypothermia (axillary temperature below 32°C). She had been admitted to the hospital two months before for an acute L4-L5 infectious spondylodiscitis without any initial neurological deficit...

Background and purpose: Until now, stroke and transient ischemic attack (TIA) have been clinically based terms which describe the presence and duration of characteristic neurological deficits attributable to intrinsic disorders of particular arteries supplying the brain, retina, or (sometimes) the spinal cord. Further, infarction has been pathologically defined as death of neural tissue due to reduced blood supply. Recently, it has been proposed we shift to definitions of stroke and TIA determined by neuroimaging results alone and that neuroimaging findings be equated with infarction...

Intramedullary spinal lesions present a wide differential diagnosis including infectious, inflammatory, traumatic, ischemic, benign, or malignant neoplastic etiologies. Using knowledge of anatomy and physiology within the spinal cord, many similar appearing entities can be parsed into a prioritized differential. The purpose of this article is to review anatomy and pathophysiology of the spinal cord, with subsequent discussion of how this knowledge can be used to differentiate several similar appearing intramedullary pathologic processes...

The limited recovery that occurs following stroke happens almost entirely in the first weeks post injury. Moreover, the efficacy of rehabilitative training is limited beyond this narrow time frame. Sprouting of spared corticospinal tract axons in the contralesional spinal cord makes a significant contribution to sensorimotor recovery, but this structural plasticity is also limited to the first few weeks after stroke. Here, we tested the hypothesis that inducing plasticity in the spinal cord during chronic stroke could improve recovery from persistent sensorimotor impairment...

OBJECTIVE: Surgery for syringomyelia generally aims to treat the underlying cause, if it is known. Optimal management is unclear for idiopathic syringomyelia, or where treatment of the putative cause has failed or is high risk. Syrinx to subarachnoid shunting is an option for these cases; a series is reported to assess the outcomes of this approach. METHODS: We retrospectively analysed the clinical and radiological features of a consecutive series of patients with syringomyelia treated with syrinx to subarachnoid shunting...

Anterior cervical discectomy and fusion (ACDF) for cord compression is a safe and effective procedure with good outcomes. However, worsening of myelopathy is the most feared adverse event of the surgery. We report the case of a 36-year-old male patient who presented with an acute non-traumatic C5-6 cervical disc herniation causing incomplete quadriparesis. He underwent an uncomplicated ACDF at C5-6, and after an initial period of improvement, he developed a delayed onset of an anterior cord syndrome on day 3, without any discerning cause...

CONTEXT: Spinal cord infarction (SCI) causes gait disturbance because of paresis, spasticity, and sensory disturbance of the lower limbs. There is no effective medical treatment for SCI, and conventional rehabilitation alone is the main approach to helping individuals work toward independent walking. The aim of this study was to evaluate the effect of gait treatment using the Hybrid Assistive Limb (HAL) on acute SCI. FINDINGS: A 61-year-old female and a 62-year-old male with incomplete paraplegia participated in this study...

Based on our previous demonstration of CXCR7 as the major mediator of CXCL12 signaling in cultured astrocytes, we have now compared astrocytic expression of the CXCL12 receptors, CXCR7 and CXCR4, during CNS development and disease. In addition, we asked whether disease-associated conditions/factors affect expression of CXCL12 receptors in astrocytes. In the late embryonic rat brain, CXCR7(+)/GFAP(+) cells were restricted to the ventricular/subventricular zone while CXCR4 was widely absent from GFAP-positive cells...

Nogo receptor-1 (NgR1) and its ligands inhibit neuronal plasticity and limit functional recovery after brain damage such as ischemic stroke. We have previously shown that lateral olfactory tract usher substance (LOTUS) antagonizes NgR1-mediated signaling. Here, we investigated whether LOTUS enhances neuronal plasticity and functional recovery after brain focal ischemia in adult mice. Focal ischemic infarcts were induced in wild-type and LOTUS-overexpressing transgenic mice via middle cerebral artery occlusion...

BACKGROUND: During scuba diving, nitrogen dissolves into the body tissues due to elevated pressure under water. During a sudden drop in pressure due to a rapid return to the water surface, arterial gas embolism can arise from pulmonary barotrauma. In a later phase, nitrogen bubbles can also arise in the venous circulation (decompression sickness). Arterial bubbles can incur vascular damage, obstruction, hypoxia and infarction. CASE DESCRIPTION: A 53-year-old healthy sport diver presented at the emergency department in a hypovolemic shock with progressive paresis of all the extremities...

In physiological conditions, adult neurons have low intracellular Cl(-) [(Cl(-))I] levels underlying the γ-aminobutyric acid (GABA)ergic inhibitory drive. In contrast, neurons have high (Cl(-))I levels and excitatory GABA actions in a wide range of pathological conditions including spinal cord lesions, chronic pain, brain trauma, cerebrovascular infarcts, autism, Rett and Down syndrome, various types of epilepsies, and other genetic or environmental insults. The diuretic highly specific NKCC1 chloride importer antagonist bumetanide (PubChem CID: 2461) efficiently restores low (Cl(-))I levels and attenuates many disorders in experimental conditions and in some clinical trials...

A 36-year-old woman with a clinical history of Friedreich ataxia and hypertrophic cardiomyopathy was found unexpectedly dead at her home. The heart showed asymmetric left ventricular hypertrophy, with an interventricular septal thickness of 20-25 mm (the remainder of the left ventricular wall measured 15 mm). Histologically, both ventricles had irregular areas of marked myocyte hypertrophy with associated interstitial fibrosis and focal myofibre disarray. There was neuronal loss within the dentate nucleus of the cerebellum, with vacuolation and axonal loss in the dorsal columns and spinocerebellar tracts of the upper cervical spinal cord...

There are complex and dynamic reflex control networks between the heart and the brain, including cardiac and intrathoracic ganglia, spinal cord, brainstem, and central nucleus. Recent literature based on animal model and clinical trials indicates a close link between cardiac function and nervous systems. It is noteworthy that the autonomic nervous-based therapeutics has shown great potential in the management of atrial fibrillation, ventricular arrhythmia, and myocardial remodeling. However, the potential mechanisms of postoperative brain injury and cardiovascular changes, particularly heart rate variability and the presence of arrhythmias, are not understood...

BACKGROUND: Choroid plexus (CP) supports the entry of monocyte-derived macrophages (MDMs) to the central nervous system in animal models of traumatic brain injury, spinal cord injury, and Alzheimer's disease. Whether the CP is involved in the recruitment of MDMs to the injured brain after ischemic stroke is unknown. METHODS: Adult male C57BL/6 mice were subjected to focal cortical ischemia by permanent occlusion of the distal branch of the right middle cerebral artery...

OBJECTIVE: We investigated the hypothesis that methane-rich saline (MS) can be used to repair spinal cord injury (SCI) in a rat model through suppressing microglial activation related to oxidative, inflammatory, and apoptotic injury. METHODS: MS was injected intraperitoneally in rats after SCI. Hematoxylin-eosin (HE) staining, oxidative stress, inflammatory parameters, and cell apoptosis were detected 72 h after SCI to determine the optimal dose. Then, we investigated the protective mechanisms and the long-term effects of MS on SCI...
