PURPOSE OF REVIEW: Posttraumatic seizures (PTS) and posttraumatic epilepsy (PTE) are common and debilitating consequences of traumatic brain injury (TBI). Early PTS result in secondary brain injury by raising intracranial pressure and worsening cerebral edema and metabolic crisis. PTE is a localization-related epilepsy strongly associated with TBI severity, but risk factors for PTE and epileptogenesis are incompletely understood and are active areas of research. Medical management of PTS in adults and children is reviewed...

Mike Yoshio Hamasaki, Marcel Cerqueira César Machado, Fabiano Pinheiro da Silva
The term "neuroinflammation" has been widely used to describe a series of acute or chronic conditions that cause inflammation in the central nervous system (CNS). Neurological damage can be a consequence of direct local injury or, secondary, of systemic or even distant inflammatory processes. In this respect, animal models have been developed to better understand the pathophysiology and, possibly, to evaluate more effective methods of treatment for these disorders. Animal models that promote alterations in blood-brain barrier permeability-the activation of microglia or astrocytes, modifications in neuropeptide expression, oxidative stress, increased apoptosis, release of inflammatory mediators, leukocyte infiltration, and brain edema-are likely to involve neuroinflammation and therefore can serve as useful models for human inflammatory CNS injury...

BACKGROUND: Early brain injury (EBI) after aneurysmal subarachnoid hemorrhage (aSAH) is defined as brain injury occurring within 72 h of aneurysmal rupture. Although EBI is the most significant predictor of outcomes after aSAH, its underlying pathophysiology is not well understood. We hypothesize that EBI after aSAH is associated with an increase in peripheral inflammation measured by cytokine expression levels and changes in associations between cytokines. METHODS: aSAH patients were enrolled into a prospective observational study and were assessed for markers of EBI: global cerebral edema (GCE), subarachnoid hemorrhage early brain edema score (SEBES), and Hunt-Hess grade...

Posterior reversible encephalopathy syndrome (PRES) is characterized by a clinical and radiological entity with the sudden onset of seizures, headache, altered consciousness, and visual disturbances in patients with the findings of reversible vasogenic subcortical edema without infarction. Hypertension, renal disease, and autoimmune disease are co-morbid conditions of PRES. Nevertheless, there have only been a few case reports of PRES in a patient with anti-glomerular basement membrane antibody glomerulonephritis (anti-GBM GN)...

MiR-126, a microRNA implicated in blood vessel integrity, angiogenesis and vascular inflammation, is markedly decreased in the sera of patients with intracerebral hemorrhage (ICH). The current study aims to evaluate the potential therapeutic effect of miR-126-3p on brain injuries in a rat model of collagenase-induced ICH. Intracerebroventricular administration of a miR-126-3p mimic significantly alleviated behavioral defects 24 h after ICH, as examined by paw placement and corner tests. ICH led to increased blood-brain barrier (BBB) permeability and cerebral edema, both of which were attenuated by miR-126-3p mimic...

Glioblastoma is highly aggressive. Early dispersal of the primary tumor renders localized therapy ineffective. Recurrence always occurs and leads to patient death. Prior studies have shown that dispersal of Glioblastoma can be significantly reduced by Dexamethasone (Dex), a drug currently used to control brain tumor related edema. However, due to high doses and significant side effects, treatment is tapered and discontinued as soon as edema has resolved. Prior analyses of the dispersal inhibitory effects of Dex were performed on tissue culture plastic, or polystyrene filters seeded with normal human astrocytes, conditions which inherently differ from the parenchymal architecture of neuronal tissue...

Early brain injury is considered to be a major risk that is related to the prognosis of subarachnoid hemorrhage (SAH). In SAH model rats, brain edema and apoptosis have been closely related with death rate and neurological function. Sirtuin 1 (SIRT1) was reported to be involved in apoptosis in cerebral ischemia and brain tumor formation through p53 deacetylation. The present study aimed to evaluate the role of SIRT1 in a rat endovascular perforation model of SAH. The SIRT1 activator resveratrol (RES) was administered 48 h prior to SAH induction and the SIRT1 inhibitor Sirtinol (SIR) was used to reverse the effects of RES on SIRT1 expression...

Intravascular large B-cell lymphoma (IVL) is a rare type of extranodal diffuse large B-cell lymphoma (DLBCL), which often infiltrates the central nervous system (CNS) during the clinical course. Cerebral hemorrhage in patients with CNS lymphoma at presentation is rare. Herein, we describe a case of secondary CNS lymphoma with intratumoral hemorrhage, which was suggested as IVL from autopsy findings. A 76-year-old Japanese man with a history of treatment for B-cell non-Hodgkin's lymphoma was transferred to our hospital in an ambulance for generalized convulsions...

Multiple sclerosis is one of the most common neurological diseases in young people. This paper dealt with an automatic biomedical aided tool involving volumetric segmentation of Multiple Sclerosis lesions. To meet this challenge, our proposed methodology requires one preliminary cerebral zones segmentation performed using a new Gaussian Mixture Model based on various databases atlases. Afterwards, lesion segmentation begins with the estimation of a lesion map which is then subjected to threshold constraints and refined by a new lesion expansion algorithm...

Although extrahepatic metastases from hepatocellular carcinoma (HCC) are present in only 5-15% of cases, they are certainly factors associated with poor prognosis. The main sites include lung, lymph nodes, bones, and adrenal glands, in descending order. Metastasis in the central nervous system is extremely rare, and the incidences vary from 0.6 to 1.7%. We report a case of a 54-year-old man previously diagnosed with alcohol-induced cirrhosis of the liver and HCC. The patient was admitted presenting progressive left hemiparesis and headache which started 2 days earlier, with no history of cranioencephalic trauma...

Hydrogen gas (H2) exerts a beneficial effect against traumatic brain injury (TBI). miR-21 is one of the most highly expressed members of small non-coding microRNA family in mammalian cells. miR-21 can improve the neurological outcome after TBI. In the present study, we investigated whether H2 treatment could improve the neurological outcome after TBI via increasing miR-21 expression. TBI was induced by controlled cortical impact (CCI) in rats. H2 treatment was given by exposure to 2% H2 from 30 minutes to 5 hours after TBI operation...

BACKGROUND: High-grade gliomas are primary brain tumors that have shown increasing incidence and unfavorable outcomes. Local control is crucial to the management of this pathology. Photodynamic therapy (PDT), based on the light-induced activation of a photosensitizer (PS), achieves local treatment by inducing selective lesions in tumor tissue. OBJECTIVES: Previous studies have reported the outcomes of PDT for glioblastoma via immunohistological data. Our study aimed to evaluate MRI findings, including diffusion, and perfusion sequences, compared with immunohistological data from the same population to address the efficiency of light fractionation...

OBJECTIVE: Quantitative and semi-quantitative MRI (qMRI) metrics provide complementary specificity and differential sensitivity to pathological brain changes compatible with brain inflammation, degeneration, and repair. Moreover, advanced magnetic resonance imaging (MRI) metrics with overlapping elements amplify the true tissue-related information and limit measurement noise. In this work, we combined multiple advanced MRI parameters to assess focal and diffuse brain changes over 2 years in a group of early-stage relapsing-remitting MS patients...

Chiari type 1 malformation (CM1) rarely causes papilloedema, which is indicative of high intracranial pressure with or without ventricular dilatation. Furthermore, concomitant brain parenchymal abnormalities have not been reported to date. In this paper, the authors report on a young woman of CM1-induced intracranial hypertension (ICH) with diffuse brain edema with a focus on venous sinus assessment, and discuss the surgical strategy. A 24-year-old woman presented to Nagoya University Hospital complaining of 4-year history of severe occipital headache and blurry vision with slowly progressive worsening...

BACKGROUND AND PURPOSE: Intracerebral hemorrhage (ICH) is a subtype of stroke with highest mortality and morbidity. Pronounced inflammation plays a significant role in the development of the secondary brain injury after ICH. Recently, SIK-2 (salt-inducible kinase-2) was identified as an important component controlling inflammatory response. Here we sought to investigate the role of SIK-2 in post-ICH inflammation and potential protective effects of SIK-2 inhibition after ICH. METHODS: Two hundred and ninety-three male CD-1 mice were used...
