Department of Neurological Sciences, Rush University Medical Center, Chicago, Illinois. Electronic address:

Fibrocartilaginous embolism (FCE) is an uncommon cause of spinal cord infarction often misdiagnosed as transverse myelitis. The mechanism of ischemia is suspected to be due to retrograde embolization of nucleus pulposus material originating from Schmorl's nodes to the spinal vessels following acute disk herniation. We describe the clinical and imaging findings of FCE in 3 healthy young women with history of trivial spinal cord trauma, and recommend that FCE should be considered in the differential diagnosis of acute myelopathy.

Spinal cord infarction is very rare condition and usually occurs in the thoracic region of the spine. The etiology is often unknown and patophysiology can be diverse. The stroke may occur while performing a surgical procedure, but it is also found in vascular diseases, for example dissecting aneurysms, vasculitis and vascular malformations. Read More

Introduction: Computed tomography-guided cervical nerve root corticosteroid injections are a commonly performed procedure for cervical radiculopathy. There have been major complications such as spinal cord infarction and posterior circulation stroke reported mostly with X-ray fluoroscopic-guided methods, however, there is relatively little data on the safety of newer CT-guided methods. The purpose of this study was to identify any major complications and evaluate the rate of minor complications from CT-guided cervical nerve root corticosteroid injections performed in a tertiary public hospital.

Dental pulp stem cells (DPSCs) are mesenchymal stem cells (MSCs) that have multipotent differentiation and a self-renewal ability. They have been useful not only for dental diseases, but also for systemic diseases. Extensive studies have suggested that DPSCs are effective for various diseases, such as spinal cord injuries, Parkinson's disease, Alzheimer's disease, cerebral ischemia, myocardial infarction, muscular dystrophy, diabetes, liver diseases, eye diseases, immune diseases, and oral diseases.

Background: Phagocytosis is a key function of myeloid cells and is highly involved in brain ischemic injury. It has been scarcely studied in vivo, thus preventing a deep knowledge of the processes occurring in the ischemic environment. Structured illumination microscopy (SIM) is a superresolution technique which helps study phagocytosis, a process involving the recruitment of vesicles sized below the resolution limits of standard confocal microscopy.

Background And Purpose: White matter hyperintensities (WMH) is identified as a marker of cerebral small vessel diseases and is a major contributor to cognitive impairment, depression, gait disturbance, and urinary incontinence. However, the risk factors for WMH in patients with type 2 diabetes mellitus (T2DM) has not been well explored. Thus, in this study, we aimed to investigate the relationship between the severity of WMH and vascular risk factors in lacunar infarction patients with T2DM. Read More

Timely reperfusion is still the most effective approach to limit infarct size in humans. Yet, despite advances in care and reduction in door-to-balloon times, nearly 25% of patients develop heart failure postmyocardial infarction, with its attendant morbidity and mortality. We previously showed that cardioprotection results from a skin incision through the umbilicus in a murine model of myocardial infarction. Read More

Pediatric emergency medicine providers must be astute at generating the differential diagnosis and performing the appropriate evaluation to promptly determine the underlying cause of new onset paraplegia. Spinal cord infarction (SCI) is a potential etiology of paraplegia in children, and fibrocartilaginous embolization is a rare underlying cause of SCI. We present an illustrative case of SCI secondary to fibrocartilaginous embolization in an otherwise healthy adolescent who developed symptoms of spinal cord dysfunction after basketball play.

Tumor excision surgeries of the spine present a distinct challenge regarding the maintenance of spinal cord blood supply because they often require preoperative embolization of segmental arteries, ligation of the corresponding nerve roots, and circumferential exposure of the dural sac. The authors present a case of delayed-onset spinal cord infarction after repeated tumor excision surgeries of the thoracic spine. A 49-year-old man had undergone a left nephrectomy for renal cell carcinoma, 2 pulmonary metastasectomies, and excision of a left sixth rib metastasis before referral to the authors' institution.

Hepatocellular carcinoma (HCC) is a common cancer worldwide with a great potential for metastatic spread. Hepatocellular carcinoma often arises in people with underlying viral hepatitides or liver cirrhosis and may present in various ways including abdominal pain, liver mass, and signs of hepatocellular decompensation.

Background: The migration of peripheral immune cells and splenocytes to the ischemic brain is one of the major causes of delayed neuroinflammation after permanent large vessel stroke. Other groups have demonstrated that leukemia inhibitory factor (LIF), a cytokine that promotes neural cell survival through upregulation of antioxidant enzymes, promotes an anti-inflammatory phenotype in several types of immune cells. The goal of this study was to determine whether LIF treatment modulates the peripheral immune response after stroke. Read More

This paper illustrates the cases of two patients with an acute onset of right brachial neuropathic pain, flaccid paralysis and contralateral thermal and thermal pain hypoesthesia, without posterior column impairment nor pyramidal signs below the segmental lesion. MRI showed right sided spinal cord infarction, in the anterior spinal artery territory between C1 and C5 in one patient and between C3 and C7 in the other. Contact Heat Evoked Potentials and Quantitative Thermal Sensory testing are consistent with contralateral, but not ipsilateral, spinothalamic tract involvement. Read More

Fatal arrhythmias, heart failure, and sudden cardiac death after myocardial ischemia/infarction are serious threats to human health. In recent years, studies have shown that spinal cord stimulation (SCS) can balance autonomic activity, inhibit myocardial structural remodeling, improve blood flow to ischemic myocardium, effectively reduce the incidence of arrhythmia, heart failure and sudden cardiac death after myocardial ischemia/infarction, but its specific mechanism has not yet been fully elucidated. The effect of SCS on cardiac function may be achieved by inhibiting neural remodeling, or by ameliorating structural remodeling and electrical remodeling. Read More

As the systematic work on the pathogenesis of the white matter injury in the spinal cord models progresses, it becomes obvious that a severe and extraordinarily protracted, destructive inflammation follows the initial injury. Appropriate anti-inflammatory therapies of sufficient duration should not only inhibit but also lead to the elimination of this destructive inflammation, thus resulting in neuroprotection of the spinal cord tissue and a greater preservation of the neurologic function. While dexamethasone, a powerful, anti-inflammatory steroid analog administered continuously by subdural infusion for 7 days inhibited severe macrophage infiltration in the cavity of injury, the dose used was remarkably toxic.

Background: Postoperative brain injury is a cause of mortality and morbidity in patients who undergo thoracic aortic replacement. Chronic microvascular white matter ischemic change (WMIC) has been shown to be associated with acute brain infarction in the general population.

Background: Electroencephalogram-based brain-computer interfaces (BCIs) represent novel human machine interactive technology that allows people to communicate and interact with the external world without relying on their peripheral muscles and nervous system. Among BCI systems, brain-actuated wheelchairs are promising systems for the rehabilitation of severely motor disabled individuals who are unable to control a wheelchair by conventional interfaces. Previous related studies realized the easy use of brain-actuated wheelchairs that enable people to navigate the wheelchair through simple commands; however, these systems rely on offline calibration of the environment.
