We describe the operative approach and management for thoracic metastatic disease in a 78-yr-old man with worsening mechanical lower back and left-sided thoracic radicular pain. Imaging of the thoracic spine revealed an osteolytic T11 mass with destruction of the left T11 pedicle and transverse process. Biopsy confirmed spinal metastasis from the liver. Preoperative angiogram was completed for localization of the artery of Adamkewicz and microparticle embolization of the left T11 intercostal artery. Surgical resection was supplemented with electrophysiological monitoring and neuronavigation...

SMTP-7 ( Stachybotrys microspora triprenyl phenol-7) is a small molecule that promotes thrombolysis and suppresses inflammation possibly through plasminogen modulation and soluble epoxide hydrolase (sEH) inhibition, respectively. Here, we demonstrate an efficacy of SMTP-7 in a severe embolic stroke model in monkeys. The middle cerebral artery was embolized by an autologous blood clot. Saline, SMTP-7, or tissue-type plasminogen activator (t-PA) (n = 5 in each group) was given after 3 hours, and neurologic deficit scoring and infarct characterization were performed after 24 hours...

Cognitive impairment is very common in stroke patients and underdiagnosed. Symptoms such as language, praxis, visuospatial, visuoconstructive and memory impairment are prominent. The screening cognitive tests available do not address some specific characteristics of stroke patients and have major limitations in relation to the most impaired cognitive domains. Objective: To test the applicability of a Brazilian version of the Oxford Cognitive Screen in a convenience sample of individuals with normal cognition...

A healthy 17-year-old boy with a high-functioning pervasive developmental disorder presented to the emergency department after having a 4-minute episode of seizure-like activity in the setting of presumed viral gastroenteritis. Within an hour of emergency department arrival, he developed a forehead-sparing facial droop, right-sided ptosis, and expressive aphasia, prompting stroke team assessment and urgent neuroimaging. Laboratory results later revealed a serum sodium of 119 mmol/L. Neurologic deficits self-resolved, and a full physical examination revealed diffuse abdominal tenderness in the lower abdomen with rebound tenderness in the right-lower quadrant...

Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) is a genetically determined disease of the cerebral vessels, characterized by recurrent ischemic strokes, dementia, and degeneration of the cerebral white matter. The condition is caused by a mutation in the NOTCH3 gene, whose product plays a great role in the development and physiology of the cardiovascular system. Magnetic resonance imaging reveals multiple hyperintensive lesions of the white matter in the T2-weighted images also in asymptomatic carriers of CADASIL and can be detected even 10-15 years prior to clinical signs...

BACKGROUND: Periprocedural stroke is a rare but life-threatening complication of percutaneous coronary intervention (PCI). Transradial intervention (TRI) is more beneficial than transfemoral intervention for periprocedural bleeding and acute kidney injuries, but its effect on periprocedural stroke has not been fully investigated. Our study aimed to assess risk predictors of periprocedural stroke according to PCI access site. METHODS AND RESULTS: Between 2008 and 2016, 17 966 patients undergoing PCI were registered in a prospective multicenter database...

Cerebral ischemia-reperfusion is a complicated pathological process. The injury and cascade reactions caused by cerebral ischemia and reperfusion are characterized by high mortality, high recurrence, and high disability. However, only a limited number of antithrombotic drugs, such as recombinant tissue plasminogen activator (r-TPA), aspirin, and heparin, are currently available for ischemic stroke, and its safety concerns is inevitable which associated with reperfusion injury and hemorrhage. Therefore, it is necessary to further explore and examine some potential neuroprotective agents with treatment for cerebral ischemia and reperfusion injury to reduce safety concerns caused by antithrombotic drugs in ischemic stroke...

Stenosis of arteries that supplies blood to the brain is one of the main causes of ischemic stroke which is the third most common cause of deaths in Europe. Atherosclerosis of carotid and vertebral arteries is responsible for 20% of the ischemic stroke cases. Stenosis may be either asymptomatic or manifested with typical neurological symptoms including motor and sensory disturbances as well as disturbances in vision and speech. However, discrete non-specific symptoms of ischemia, including headaches and vertigo, tinnitus and hearing loss, are also quite common...

INTRODUCTION: Stroke is the clinical designation for a rapidly developing loss of brain function due to an interruption in the blood supply to all or part of the brain. It is the third cause of death in adults and one of the top 10 causes in pediatric age. The perinatal period of onset is the second only to adult age group in the incidence of stroke. Arterial ischemic stroke during childhood occurs most frequently in the perinatal period with an incidence of 1 out 2300-5000 live infant births...

Electroacupuncture (EA) may stimulate neurogenesis in animal models of ischemic stroke; however, the associated mechanisms are not clear. The present study aimed to evaluate the neurogenesis efficacy of EA on ischemic stroke and the underlying associated mechanisms. A model of middle cerebral artery occlusion (MCAO) was employed as the rat model of brain ischemia and reperfusion. EA treatment at the GV20 (Baihui) and GV14 (Dazhui) acupoints was conducted for 30 min daily following MCAO. Immunofluorescence was performed to measure the number of bromodeoxyuridine (BrdU)/nestin- or BrdU/doublecortin (DCX)-positive cells in the sham, MCAO and MCAO + EA groups...

Ischemic stroke is one of the leading causes of death and disability globally and has been regarded as a major public health problem. Understanding the mechanism of ischemia/reperfusion (I/R)-induced oxidative stress injury may provide new treatment for ischemic stroke. Kelch-like ECH-associated protein 1 (Keap1)/ NF-E2-related factor 2 (Nrf2)/ antioxidant response elements (ARE) signaling pathway has been considered to be the major cellular defense against oxidative stress. In the present study, our objective is to evaluate the molecular mechanism of miR-34b/Keap1 in modulating focal cerebral I/R induced oxidative injury...

The plasminogen activation (PA) system was originally thought to exclusively promote the degradation of fibrin by catalyzing the conversion of plasminogen into plasmin via two serine proteinases: tissue-type plasminogen activator (tPA) and urokinase-type plasminogen activator (uPA). However, experimental evidence accumulated over the last 30 years indicates that tPA and uPA are also found in the central nervous system (CNS), where they have a plethora of functions that not always require plasmin generation or fibrin degradation...
