Intracerebral hemorrhage (ICH) is a devastating subtype of stroke that lacks effective therapy and reliable prognosis. Neovascularization following ICH is an essential compensatory response that mediates brain repair and modulates the clinical outcome of stroke patients. However, the mechanism that dictates this process is unknown. Bone marrow-derived endothelial progenitor cells (EPCs) promote endothelial repair and contribute to ischemia-induced neovascularization. The human Tp53 gene harbors a common single-nucleotide polymorphism (SNP) at codon 72, which yields an arginine-to-proline amino-acidic substitution (Arg72Pro) that modulates the apoptotic activity of the p53 protein...

AIM: In this study, we investigated the effects of genistein in a rat model of sciatic nerve crush injury and complete sciatic nerve transection. The effects of genistein were compared with those of gabapentin, which is widely used in clinical practice for peripheral nerve injury. MATERIAL AND METHODS: Forty-eight rats were randomly divided into six groups (n = 8 for all groups): group 1 (sham); group 2, sciatic nerve crush injury (control); group 3, sciatic nerve crush injury + genistein 20 mg/kg; group 4, sciatic nerve crush injury + gabapentin 90 mg/kg; group 5, sciatic nerve transection + genistein 20 mg/kg; group 6, sciatic nerve transection + gabapentin 90 mg/kg...

BACKGROUND: Increased spinal cord perfusion and blood pressure goals have been recommended for spinal cord injury (SCI). Penetrating SCI is associated with poor prognosis, but there is a paucity of literature examining the role of vasopressor administration for the maintenance of mean arterial pressure (MAP) goals in this patient population. OBJECTIVE: To elucidate this topic and to determine the efficacy of vasopressor administration in penetrating SCI by examining a case series of consecutive penetrating SCIs...

BACKGROUND AND PURPOSE: Intracerebral hemorrhage (ICH) is a devastating disease without a proven therapy to improve long-term outcome. Considerable controversy about the role of surgery remains. Minimally invasive endoscopic surgery for ICH offers the potential of improved neurological outcome. METHODS: We tested the hypothesis that intraoperative computerized tomographic image-guided endoscopic surgery is safe and effectively removes the majority of the hematoma rapidly...

BACKGROUND: Atlanto-occipital dislocation (AOD) is a rare but severe sequela of high energy trauma. Children are at increased risk, due to their immature spine and biomechanical characteristics. LITERATURE REVIEW: The prevailing mechanism of injury is motor vehicle collision as passenger. AOD commonly presents with cardiorespiratory arrest, spinal cord injury or cranial nerve deficits. Concomitant injuries, such as traumatic brain injury, are frequently encountered...

We present a 62-year-old lady admitted in our hospital with two episodes of acute ischemic stroke about 2 weeks apart. She was evaluated for acute ischemic stroke and was thrombolysed for recent stroke in right MCA territory first time. On further evaluation, she was found to have a RVOT mass. A transthoracic and transesophageal echocardiogram revealed a PFO and a large, 5.1cm×2.3cm, ovoid, well circumscribed, echogenic mass in the right ventricle outflow tract attached by small pedicle to the ventricular side of anterior tricuspid leaflet, partly obstructing the right ventricular outflow tract and protruding through the pulmonic valve during systole...

Carotid artery dissection (CAD) is a frequent cause of stroke, accounting for up to 25% of all ischemic strokes in young and middle-aged patients.(1,2) It may be traumatic or spontaneous, with multi-factorial etiology. A tear in the arterial wall causes intrusion of blood within its layers, producing intra-luminal stenosis, or aneurysmal dilatation.(3) Thrombo-embolism arising from this anatomic disruption has been postulated as the essential stroke mechanism in CAD.(4) Bilateral internal carotid artery dissection (ICAD) has been rarely reported...

BACKGROUND: Slow waves (less than 1 Hz) are the most important electroencephalogram signatures of nonrapid eye movement sleep. While considered to have a substantial importance in, for example, providing conditions for single-cell rest and preventing long-term neural damage, a disturbance in this neurophysiologic phenomenon is a potential indicator of brain dysfunction. METHODS: Since, in healthy individuals, slow waves can be induced with anesthetics, the authors tested the possible association between hypoxic brain injury and slow-wave activity in comatose postcardiac arrest patients (n = 10) using controlled propofol exposure...

Using a model of middle cerebral artery occlusion (MCAO), we have previously demonstrated that treadmill exercise promotes angiogenesis in the ischemic penumbra through caveolin-1/VEGF signaling pathways. However, the function of caveolin-1/VEGF signaling in neurogenesis after MCAO has not been determined. In this study, we aimed to investigate the potential of treadmill exercise to promote neurogenesis after MCAO and whether caveolin-1/VEGF signaling pathways are involved. After MCAO, rats were subjected to a program of treadmill exercise...

Awake craniotomy for brain tumours  Awake neurosurgery is a useful method in lesions near eloquent brain areas, particularly low-grade gliomas.The aim is to maximise tumour resection and preserve neurological function. We performed 40 primary awake surgeries and 8 residual surgeries. Patients were operated awake throughout the procedure or with a laryngeal mask and general anaesthesia during the opening stage and then awake during intracerebral surgery. Language and motor function were mapped with direct cortical stimulation, motor evoked potential and standardised neurological testing...

Posterior reversible encephalopathy syndrome (PRES) has been described in the context of uncontrolled hypertension, eclampsia, renal disease and autoimmune conditions, or in patients treated with chemotherapy or immunosuppressive agents. In contrast, we report the occurrence of PRES in a patient with untreated metastatic transitional cell carcinoma. The case emphasizes important diagnostic challenges associated with atypical presentations without "typical" risk factors and the limitations of common diagnostic imaging modalities...

INTRODUCTION: Primary central nervous system lymphoma (PCNSL) of T-cell origin is an exceptionally rare, highly malignant intracranial neoplasm. Although such a tumor typically presents with a focal mass lesion. CASE REPORT: Past medical history of a 26-year-old male patient with a PCNS lymphoma of T-cell origin was not suggestive of intracranial pathology or any disorder of other organs and organic systems. To achieve a gross total tumor resection, surgery was performed via osteoplastic craniotomy using the left frontal transcortical transventricular approach...

In view of the failure of pharmacological therapies, alternative strategies promoting post-stroke brain repair are needed. Post-conditioning is a potentially promising therapeutic strategy, which induces acute neuroprotection against ischemic injury. To elucidate longer lasting actions of ischemic post-conditioning, mice were exposed to a 60-min stroke and post-conditioning by an additional 10-min stroke that was induced 10 min after reperfusion onset. Animals were sacrificed 24 h or 28 days post-stroke...

PURPOSE: The spinal epidural angiolipomas are rare expansive processes made of mature lipomatous and angiomatous elements. They often have a benign character. Their etiology, pathogenesis remains uncertain, and it is a cause of spinal cord compression. The magnetic resonance imaging is the most important neuroradiological examination. Histological examination is the only examination to confirm the diagnosis. Surgery is the treatment of choice. METHODS: A retrospective study of all patients operated on for a spinal epidural angiolipoma at the Department of Neurosurgery at the National Institute of Neurology of Tunis between January 2000 and December 2014 (15 years) was performed...

Neurological complications of haemolytic uraemic syndrome (HUS) include altered states of consciousness, seizures, ischaemic stroke and encephalopathy. Adult-onset HUS is uncommon, and there is only a limited literature reporting neurological complications in this population. We report an adult with Shiga toxin-associated HUS complicated by focal-onset non-convulsive status epilepticus, who made a full neurological recovery.
