A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.

Transforming growth factor-alpha acting at the epidermal growth factor receptor reduces infarct volume after permanent middle cerebral artery occlusion in rats. (1/3121)

Transforming growth factor-alpha (TGF-alpha) is a ligand for the epidermal growth factor (EGF) receptor (EGFR), and is more abundant than EGF in the brain. The authors studied whether administration of exogenous TGF-alpha into the brain can protect neurons against ischemia in a model of permanent middle cerebral artery (MCA) occlusion in the rat, and whether any effect of TGF-alpha was mediated by EGFR by administering 4,5-dianilinophthalimide (DAPH), a protein-tyrosine kinase inhibitor with high selectivity for EGFR. Rats received either TGF-alpha (10 or 25 ng), DAPH (100 ng), DAPH plus TGF-alpha (25 ng), or vehicle in the ipsilateral first ventricle. Drugs were administered twice: 30 minutes before and 30 minutes after MCA occlusion, and infarct volume was evaluated 24 hours later. Transforming growth factor-alpha at the dose of 25 ng caused a statistically significant reduction of infarct volume (60%) in relation to ischemic rats administered vehicle. This reduction was no longer seen when TGF-alpha was administered in combination with DAPH. The present results show that TGF-alpha can protect neurons from ischemic damage, and that this effect is mediated by EGFR. It is suggested that activation of EGFR-mediated intracellular signalling pathways contributes to the survival of neural cells susceptible to ischemic injury.  (+info)

Synergistic protective effects of antioxidant and nitric oxide synthase inhibitor in transient focal ischemia. (2/3121)

Both nitric oxide synthase (NOS) inhibitors and free radical scavengers have been shown to protect brain tissue in ischemia-reperfusion injury. Nitric oxide and superoxide anion act via distinct mechanisms and react together to form the highly deleterious peroxynitrite. Therefore the authors examined the effects and the interaction between the NOS inhibitor, NG nitro-L-arginine (LNA) and the antioxidant/superoxide scavenger, di-tert-butyl-hydroxybenzoic acid (DtBHB) in the rat submitted to 2 hours of middle cerebral artery occlusion. Posttreatment was initiated 4 hours after the onset of ischemia and infarct volume was measured at 48 hours. The dose-related effect of LNA resulted in a bell-shaped curve: 15, 56, 65, and 33% reduction of total infarct for 0.03, 0.1, 0.3, and 1 mg/kg (intravenously [IV]) respectively and 11% increase in infarct volume for 3 mg/kg (IV). Whereas DtBHB (20 mg/kg; intraperitoneally [IP]) was ineffective, the dose of 60 mg/kg produced 65% protection in infarct volume. The combination of a subthreshold dose of LNA (0.03 mg/kg; IV) and DtBHB (20 mg/kg; IP) resulted in significant reduction (49%) in infarct volume. These results show that LNA and DtBHB act synergistically to provide a consistent neuroprotection against ischemic injury when administered 4 hours after ischemia. This suggests that nitric oxide and free radicals are involved and interact in synergy in ischemia-reperfusion injury.  (+info)

N-Acetylaspartate distribution in rat brain striatum during acute brain ischemia. (3/3121)

Brain N-acetylaspartate (NAA) can be quantified by in vivo proton magnetic resonance spectroscopy (1H-MRS) and is used in clinical settings as a marker of neuronal density. It is, however, uncertain whether the change in brain NAA content in acute stroke is reliably measured by 1H-MRS and how NAA is distributed within the ischemic area. Rats were exposed to middle cerebral artery occlusion. Preischemic values of [NAA] in striatum were 11 mmol/L by 1H-MRS and 8 mmol/kg by HPLC. The methods showed a comparable reduction during the 8 hours of ischemia. The interstitial level of [NAA] ([NAA]e) was determined by microdialysis using [3H]NAA to assess in vivo recovery. After induction of ischemia, [NAA]e increased linearly from 70 micromol/L to a peak level of 2 mmol/L after 2 to 3 hours before declining to 0.7 mmol/L at 7 hours. For comparison, [NAA]e was measured in striatum during global ischemia, revealing that [NAA]e increased linearly to 4 mmol/L after 3 hours and this level was maintained for the next 4 h. From the change in in vivo recovery of the interstitial space volume marker [14C]mannitol, the relative amount of NAA distributed in the interstitial space was calculated to be 0.2% of the total brain NAA during normal conditions and only 2 to 6% during ischemia. It was concluded that the majority of brain NAA is intracellularly located during ischemia despite large increases of interstitial [NAA]. Thus, MR quantification of NAA during acute ischemia reflects primarily changes in intracellular levels of NAA.  (+info)

Early diagnosis of central nervous system aspergillosis with combination use of cerebral diffusion-weighted echo-planar magnetic resonance image and polymerase chain reaction of cerebrospinal fluid. (4/3121)

We treated a patient diagnosed as central nervous system (CNS) aspergillosis with the combined use of cerebral diffusion-weighted echo-planar magnetic resonance imaging (DWI) and polymerase chain reaction of the cerebrospinal fluid (CSF-PCR). DWI, a cutting-edge imaging modality to reveal the earliest changes of cerebral infarction, detected cerebral fungal embolization when the conventional computed tomographic scan and magnetic resonance imaging failed to reveal it. CSF-PCR demonstrated the presence of Aspergillus-specific DNA in the specimen, when the conventional examination and culture of CSF were nonspecific or negative. These diagnostic methods could be useful in the early diagnosis of CNS aspergillosis.  (+info)

Delayed increase in infarct volume after cerebral ischemia: correlations with thrombolytic treatment and clinical outcome. (5/3121)

BACKGROUND AND PURPOSE: Growing experimental evidence indicates that the development of cerebral ischemic damage is slower than previously believed. The aims of this work were (1) to study the evolution of CT hypoattenuation between 24 to 36 hours and 7 days in ischemic stroke patients; (2) to evaluate whether thrombolytic treatment given within 6 hours of stroke affects delayed infarction evolution; and (3) to investigate possible correlations between lesion volume changes over time and clinical outcome. METHODS: Of 620 patients included in the European Cooperative Acute Stroke Study 1 (ECASS1), we selected 450 patients whose control CT scans at day 1 (CT1) and day 7 (CT7) were available. They had been randomly divided into 2 groups: 206 patients had been treated with rtPA and 244 with placebo. CT1 and CT7 were classified according to the location of the infarct. The volume of CT hypoattenuation was measured using the formula AxBxC/2 for irregular volumes. The 95% confidence interval of inter- and intrarater variability was used to determine whether significant changes in lesion volume had occurred between CT1 and CT7. Clinical severity was evaluated by means of the Scandinavian Stroke Scale (SSS) at entry (SSS0) and at day 30 (SSS30). RESULTS: Mean lesion volumes were significantly (P<0.0001) higher at day 7 than at day 1 in all the subgroups of patients and particularly in patients with a subcortical lesion. Of the 450 patients studied, 287 (64%) did not show any significant change in lesion volume between CT1 and CT7, 143 (32%) showed a significant increase and the remaining 20 (4%) a significant decrease. No significant correlation was observed between treatment and lesion evolution between CT1 and CT7. Both clinical scores (SSS0 and SSS30) and degree of neurological recovery were significantly (P<0.05) lower in the subgroup of patients with a significant lesion volume increase than in the other 2 groups. CONCLUSIONS: In approximately two thirds of patients, infarct size is established 24 to 36 hours after stroke onset, whereas in the remaining one third, changes in lesion volume may occur later than the first 24 to 36 hours. Many factors may be responsible for delayed infarct enlargement and for a lower degree of clinical recovery, both of which may occur despite early recombinant tissue plasminogen activator treatment.  (+info)

Carotid endarterectomy and intracranial thrombolysis: simultaneous and staged procedures in ischemic stroke. (6/3121)

PURPOSE: The feasibility and safety of combining carotid surgery and thrombolysis for occlusions of the internal carotid artery (ICA) and the middle cerebral artery (MCA), either as a simultaneous or as a staged procedure in acute ischemic strokes, was studied. METHODS: A nonrandomized clinical pilot study, which included patients who had severe hemispheric carotid-related ischemic strokes and acute occlusions of the MCA, was performed between January 1994 and January 1998. Exclusion criteria were cerebral coma and major infarction established by means of cerebral computed tomography scan. Clinical outcome was assessed with the modified Rankin scale. RESULTS: Carotid reconstruction and thrombolysis was performed in 14 of 845 patients (1.7%). The ICA was occluded in 11 patients; occlusions of the MCA (mainstem/major branches/distal branch) or the anterior cerebral artery (ACA) were found in 14 patients. In three of the 14 patients, thrombolysis was performed first, followed by carotid enarterectomy (CEA) after clinical improvement (6 to 21 days). In 11 of 14 patients, 0.15 to 1 mIU urokinase was administered intraoperatively, ie, emergency CEA for acute ischemic stroke (n = 5) or surgical reexploration after elective CEA complicated by perioperative intracerebral embolism (n = 6). Thirteen of 14 intracranial embolic occlusions and 10 of 11 ICA occlusions were recanalized successfully (confirmed with angiography or transcranial Doppler studies). Four patients recovered completely (Rankin 0), six patients sustained a minor stroke (Rankin 2/3), two patients had a major stroke (Rankin 4/5), and two patients died. In one patient, hemorrhagic transformation of an ischemic infarction was detectable postoperatively. CONCLUSION: Combining carotid surgery with thrombolysis (simultaneous or staged procedure) offers a new therapeutic approach in the emergency management of an acute carotid-related stroke. Its efficacy should be evaluated in interdisciplinary studies.  (+info)

An 18-mer peptide fragment of prosaposin ameliorates place navigation disability, cortical infarction, and retrograde thalamic degeneration in rats with focal cerebral ischemia. (7/3121)

It was previously reported that prosaposin possesses neurotrophic activity that is ascribed to an 18-mer peptide comprising the hydrophilic sequence of the rat saposin C domain. To evaluate the effect of the 18-mer peptide on ischemic neuronal damage, the peptide was infused in the left lateral ventricle immediately after occlusion of the left middle cerebral artery (MCA) in stroke-prone spontaneously hypertensive (SP-SH) rats. The treatment ameliorated the ischemia-induced space navigation disability and cortical infarction and prevented secondary thalamic degeneration in a dose-dependent manner. In culture experiments, treatment with the 18-mer peptide attenuated free radical-induced neuronal injury at low concentrations (0.002 to 2 pg/mL), and the peptide at higher concentrations (0.2 to 20 ng/mL) protected neurons against hypoxic insult. Furthermore, a saposin C fragment comprising the 18-mer peptide bound to synaptosomal fractions of the cerebral cortex, and this binding decreased at the 1st day after MCA occlusion and recovered to the preischemic level at the 7th day after ischemia. These findings suggest that the 18-mer peptide ameliorates neuronal damage in vivo and in vitro through binding to the functional receptor, although the cDNA encoding prosaposin receptor has not been determined yet.  (+info)

Factor V Leiden and antibodies against phospholipids and protein S in a young woman with recurrent thromboses and abortion. (8/3121)

We describe the case of a 39-year-old woman who suffered two iliofemoral venous thromboses, a cerebral ischemic infarct and recurrent fetal loss. Initial studies showed high levels of antiphospholipid antibodies (APAs) and a moderate thrombocytopenia. After her second miscarriage, laboratory diagnosis revealed that the woman was heterozygous for the factor V Leiden mutation and had a functional protein S deficiency as well as anti-protein S and anti-beta 2-glycoprotein I antibodies. The impairment of the protein C pathway at various points could well explain the recurrent thromboses in the patient and supports the role of a disturbed protein C system in the pathophysiology of thrombosis in patients with APAs.  (+info)

We previously reported that major depression developing during or after the presenile period is frequently combined with silent cerebral infarction and that these patients have a high risk of stroke. Therefore, we investigated whether the background factors and clinical symptoms of patients with major depression with silent cerebral infarction [SCI(+)] different from those in patients with major depression without silent cerebral infarction [SCI(-)] before medical treatment.. Patients with major depression with onset after 50 years of age were classified based on magnetic resonance imaging findings into the SCI(+) (n = 37) or SCI(-) (n = 20) group. The diagnostic criteria for major depression were those of the American Psychiatry Association (DSM-III-R). Patients with stroke or focal neurological symptoms were excluded. The SCI(+) group was subclassified according to whether the infarction area was perforating, cortical, or mixed artery. Family history of affective disorder, risk factors for ...
Background: Atherosclerotic middle cerebral artery (MCA) disease may produce subcortical infarction either in the upper part (corona radiata, CR) or in the lower area (internal capsule, IC) of the pyramidal tract. The study aimed to see whether the location of MCA stenosis (proximal vs distal) determines the location of subcortical infarction.. Methods: 62 consecutive patients who developed an acute (,72 h) infarction either on the CR or IC confirmed by diffusion-weighted MRI due to corresponding focal MCA M1 stenosis assessed by MR angiography were studied. The distance between the MCA origin and the centre of stenotic portion (S) and that between the MCA origin and its bifurcation site (M) were measured. Based on the S/M ratio, stenotic lesions were divided into proximal and distal. The relationship between the location of arterial stenosis and the location of infarcts was analysed.. Results: Thirteen of 31 patients (41.9%) with proximal M1 stenosis had IC lesions, while 26 (83.9%) of 31 ...
BACKGROUND: Sickle cell disease (SCD) is one of the commonest severe monogenic disorders in the world, due to the inheritance of two abnormal haemoglobin (beta globin) genes. SCD can cause severe pain, significant end-organ damage, pulmonary complications, and premature death. Silent cerebral infarcts are the commonest neurological complication in children and probably adults with SCD. Silent cerebral infarcts also affect academic performance, increase cognitive deficits and may lower intelligence quotient. OBJECTIVES: To assess the effectiveness of interventions to reduce or prevent silent cerebral infarcts in people with SCD. SEARCH METHODS: We searched for relevant trials in the Cochrane Library, MEDLINE (from 1946), Embase (from 1974), the Transfusion Evidence Library (from 1980), and ongoing trial databases; all searches current to 19 September 2016. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register: 06 October 2016. SELECTION CRITERIA: Randomised controlled

PY - 1991/1/1. Y1 - 1991/1/1. N2 - We reviewed the one-month mortality among 213 patients aged fifteen to forty-five years (mean thirty-five) with acute cerebral infarction (CI) evaluated during the period July 1, 1977, to February 1, 1988. Atherosclerotic cerebral infarction (ACI) was diagnosed in 59 (27.7%) patients, 53 (24.9%) had non- atherosclerotic vasculopathies (NAV); 46 (21.6%) had cardioembolic infarcts (CEI). Hematologically related disorders were diagnosed in 30 (14.1%) patients; the cause of CI could not be established in 25 (11.7%) patients. Fourteen patients (9 men, 5 women, mean age 34.8 years), (6.6%) died within thirty days of their CI: 7 had CEI (7/46, 15.2%); 4 had ACI (4/59, 6.7%); and 3 had NAV (3/53, 5.6%). Our data suggest that young patients with acute CI have a thirty-day ...
A cerebral infarction is a type of ischemic stroke resulting from a blockage in the blood vessels supplying blood to the brain. It can be atherothrombotic or embolic. Stroke caused by cerebral infarction should be distinguished from two other kinds of stroke: cerebral hemorrhage and subarachnoid hemorrhage. A cerebral infarction occurs when a blood vessel that supplies a part of the brain becomes blocked or leakage occurs outside the vessel walls. This loss of blood supply results in the death of tissue in that area. Cerebral infarctions vary in their severity with one third of the cases resulting in death. ...

Aim. The aims of the study were to evaluate prevalence of silent cerebral infarctions (SCI) and determine their clinical and echocardiographic predictors in patients with atrial fibrillation (AF). Patients and methods. In prospective cross sectional study we examined 134 patients with non-valvular AF. Clinical examination, laboratory tests, transoesophageal, transthoracic echocardiography and multislice computed tomography of the brain were performed for all patients. According to current guidelines, SCI was defined as imaging (≥3 mm) or neuropathological evidence of central nervous system infarction, without a history of acute neurological dysfunction attributable to the lesion. Results. Silent cerebral infarctions were detected in 34.3% (n = 46) of patients, and infarctions ≥ 15 mm (mean diameter 31.3 mm) were detected in 11.2% (n = 15) of patients. Superficial SCIwere found in 12.7%and basal SCI in 21.6% of cases. In multivariate analysis low creatinine clearance , 90 ml/min was ...

A previous study suggested that occlusive diseases of small penetrating arteries account for most anterior choroidal artery (AChA) territory infarcts, but half of the patients did not have an echocardiogram. Cases of AChA territory infarcts associated with internal carotid artery stenosis or atrial fibrillation suggest that this hypothesis may be wrong. The aim of this study was to determine the mechanism of 16 nonselected consecutive AChA territory infarcts.. The study population consisted of 8 men and 8 women aged 17 to 89 years. They underwent a computed tomographic scan at the acute stage, Doppler ultrasonography and B-mode echotomography of the cervical arteries, bidimensional transthoracic echocardiography, and cerebral magnetic resonance imaging, replaced by a second computed tomographic scan in 3 patients. Ten patients underwent cerebral angiography. We defined the presumed cause of stroke according to the criteria used in the trial of Org 10172 in acute stroke treatment.. The presumed ...
OBJECTIVE: To assess various aspects of visual function at school age in children with neonatal cerebral infarction. PATIENTS AND METHODS: Sixteen children born at term, who had cerebral infarction of perinatal onset on neonatal magnetic resonance imaging (MRI) were assessed using a battery of visual tests. This included measures of crowding acuity (Cambridge Crowding Cards), stereopsis (TNO test), and visual fields. The results of the visual assessment were compared with the type and the extent of the lesion observed on neonatal MRI. RESULTS: Only six of the 16 children (28%) had some abnormalities of visual function on these tests. Visual abnormalities were more common in children with more extensive lesions involving the main branch of the middle cerebral artery and were less often associated with lesions in the territory of one of the cortical branches of the middle cerebral artery. The presence of visual abnormalities was not always associated with the involvement of optic radiations or occipital
Objective. The aim of this study was to assess neuromotor function at school age in children who had cerebral infarction on neonatal magnetic resonance imaging (MRI).. Design. Twenty-two children with evidence of cerebral infarction on neonatal brain MRI (18 with arterial infarction and 4 with border-zone lesions) were assessed at school age with a structured neurologic examination and the Movement Assessment Battery for Children, a battery of tests designed to assess motor function.. Results. Of the 22 children, 6 (30%) had hemiplegia and a further 7 (30%) showed some neuromotor abnormality such as asymmetry on the neurologic examination (n = 4) or poor scores on the neuromotor test without any sign of asymmetry (n = 3). The remaining 9 children had a normal motor outcome. Hemiplegia was found only in children who had concomitant involvement of hemisphere, internal capsule, and basal ganglia on brain MRI. Children with involvement of the internal capsule, associated either with basal ganglia or ...
Previous chronic cerebral infarction is predictive for new cerebral ischemia after carotid endarterectomy. - Mehmet Besir Akpinar, Veysel Sahin, Neslin Sahin, Ahmet Feyzi Abacilar, İlker Kiris, Ihsan Sami Uyar, Faik Fevzi Okur
This study shows that a group of hospital doctors, many of whom were experienced in interpreting CT on stroke patients, are not very good at recognising cerebral infarction on CT within six hours of the stroke, and even worse at judging when an infarct occupies a third or more of the MCA territory.. The experience of the doctor and knowledge of the patients symptoms did not improve this significantly. However, the high repeatability of their results between readings (both for coding normalv abnormal and whether the patient should be randomised in a stroke treatment trial) suggests consistency of observer coding (despite repeatedly failing to recognise the true early infarct signs). Although the observers failed to recognise the early infarct signs that were present, they rarely said that a sign was present when it wasnot. Worryingly, hypodensity, the sign that was particularly used in trials and guidelines to identify the extent of the infarct (to determine whether one third of the MCA ...
Cerebral infarction is a major contributor to poor outcome after subarachnoid hemorrhage (SAH). While usually considered a complication of delayed cerebral ischemia (DCI), infarcts may also occur early, in relation to initial brain injury or aneurysm
Background: The role of each nitric oxide synthase (NOS) isoform in the pathogenesis of cerebral infarction has been studied in individual NOS isoform-deficient mice. It has been reported that, in a model of middle cerebral artery occlusion (MCAO), neuronal and inducible NOSs exacerbate cerebral infarction, whereas endothelial NOS conversely alleviates cerebral infarction. Although the role of the whole NOSs system in cerebral infarction has been examined in pharmacological studies with non-selective NOS inhibitors, the results are quit inconsistent, possibly because of non-specificity of the agents. In this study, we addressed this point in mice in which all three NOS genes are completely disrupted.. Method and Results: We newly generated triple NOSs-deficient mice and wild-type littermates by crossbreeding single NOS-/- mice. Transient (1 hour) and permanent MCAO was performed in male triple NOSs-/- and wild-type mice at 8-12 weeks of age (n=9-11). Cerebral infarct size was evaluated by ...
TY - JOUR. T1 - Decreases in Electrocardiographic R-Wave Amplitude and QT Interval Predict Myocardial Ischemic Infarction in Rhesus Monkeys with Left Anterior Descending Artery Ligation.

N2 - Clinical studies have demonstrated the predictive values of changes in electrocardiographic (ECG) parameters for the preexisting myocardial ischemic infarction. However, a simple and early predictor for the subsequent development of myocardial infarction during the ischemic phase is of significant value for the identification of ischemic patients at high risk. The present study was undertaken by using non-human primate model of myocardial ischemic infarction to fulfill this gap. Twenty male Rhesus monkeys at age of 2-3 years old were subjected to left anterior descending artery ligation. This ligation was performed at varying ...

A registry of consecutive patients who were admitted and diagnosed with acute myocardial infarction or acute cerebral infarction were conducted at the Guangdong General Hospital or the First Affiliated Hospital of Guangzhou University of Chinese Medicine, Yue Bei Peoples Hospital, China, between January 2000 and December 2016. The adverse clinical outcomes, including all-cause mortality, were followed from the date of admission for acute myocardial infarction or acute cerebral infarction until study end (December 31, 2016). All-cause mortality, including the date of death, was identified from the electronic hospitalization data, phone follow-up, and confirmed by the household registration (HUKOU) system, a record of registration required by law in China. Baseline characteristics, including major treatment of acute myocardial infarction or acute cerebral infarction, estimated glomerular filtration rate (eGFR) and proteinuria, were collected. Demographic data were determined from the electronic ...

Cerebrovascular Disease - abnormality of the brain resulting from pathological processes of the blood vessels any lesions of the vessel wall, occlusion of vessel lumen by an embolus or thrombosis, rupture of the vessel, altered permeability of the vessel wall or increased viscosity or other changes of the blood quality. Equally important are the metabolic and chemical changes that occur within the brain. Minor Traumatic Brain Injury , ischemic cerebral infarction ...
A cerebral infarction is an area of necrotic tissue in the brain resulting from a blockage or narrowing in the arteries supplying blood and oxygen to the brain. The restricted oxygen due to the restricted blood supply causes an ischemic stroke that can result in an infarction if the blood flow is not restored within a relatively short period of time. The blockage can be due to a thrombus, an embolus or an atheromatous stenosis of one or more arteries. Which arteries are problematic will determine which areas of the brain are affected (infarcted). These varying infarcts will produce different symptoms and outcomes. About one third will prove fatal. There are various classification systems for a cerebral infarction. The Oxford Community Stroke Project classification (OCSP, also known as the Bamford or Oxford classification) relies primarily on the initial symptoms. Based on the extent of the symptoms, the stroke episode is classified as total anterior circulation infarct (TACI), partial anterior ...

Design: The rat group with treadmill training (n = 10) were compared with the rat group without treadmill training (n = 10) after 2.5 hrs of transient middle cerebral artery occlusion. Motor performance measured by the rotarod test and alteration of protein expression using two-dimensional electrophoresis based on proteomics in the cerebellum were examined. Results: In behavioral evaluation, the mean latency until falling from the rotating rod in the group with treadmill training was significantly longer (P , 0.01) than that in ...
Our findings indicate that, in children with MCA territory infarcts, although the functional sequelae of small lesions might be variable, infarction of more than 10% ICV is associated with pronounced residual deficits.. There are methodological constraints inherent in measuring infarct volumes in the manner described here. The reproducibility of measuring individual volumes in the our study was compromised by subjectively defining the lesion boundaries, both in the acute and chronic stages. This was especially difficult in the case of small lesions, as is apparent from the data presented in table 2, where relatively small absolute differences in measurement resulted in large percentage differences in repeated measurements. In contrast, the reproducibility of the ICV measurements was good.. The natural history of cerebral infarction on MRI is for signal hyperintensity and swelling on T2 weighted images to be apparent around six to 12 hours after symptom onset.11 Chronic infarcts show signal ...
One-hundred patients had attempted endovascular treatment. At procedure end, 23% were thrombolysis in cerebral infarction 0-1, 31% thrombolysis in cerebral infarction 2A, 28% thrombolysis in cerebral infarction 2B, and 18% thrombolysis in cerebral infarction 3. More favorable thrombolysis in cerebral infarction-reperfusion scores were associated with greater magnetic resonance imaging reperfusion (P , 0·001). thrombolysis in cerebral infarction scores correlated with 30-day favorable clinical response (P = 0·041) and 90-day modified Rankin Scale 0-2 (P = 0·008). These correlations were significant for target mismatch patients at 30 days (P = 0·034) and 90 days (P = 0·003). Infarct growth was strongly associated with poorer thrombolysis in cerebral infarction scores in target mismatch patients (P , 0·001). Patients with thrombolysis in cerebral infarctionnfarction 2A reperfusion had less magnetic resonance imaging reperfusion (P = 0·004) and poorer clinical outcome at 90 days (P = 0·01) ...
Editor-Christopher J Weir and colleagues conclude from their study of a cohort of 750 non-diabetic patients with stroke that hyperglycaemia (plasma glucose concentration ,8 mmol/l) during the acute phase has an adverse influence on outcome and that this is independent of severity of stroke.1 Stroke severity was assessed in a limited way using only the Oxfordshire community stroke project classification and time to resolution of symptoms (≤72 hours or ,72 hours), both of which are relatively inaccurate measures. When two variables are closely correlated-for example, stroke severity and glucose concentration-the one that is most accurately measured (glucose concentration) will always emerge as the strongest explanatory variable in multiple regression even if it is, in fact, less important.2. We have produced a series of validated models to predict the probability of survival and disability using the 530 patients from the Oxfordshire community stroke project who were seen within 30 days of their ...
In last decade, similar to myocardial infarction treatment, thrombolytic drugs were introduced in the therapy of cerebral infarction. The use of intravenous rtPA therapy can be advocated in patients who arrive to stroke unit and can be fully evaluated within 3 h of the onset.. If cerebral infarction is caused by a thrombus occluding blood flow to an artery supplying the brain, definitive therapy is aimed at removing the blockage by breaking the clot down (thrombolysis), or by removing it mechanically (thrombectomy). The more rapidly blood flow is restored to the brain, the fewer brain cells die. In increasing numbers of primary stroke centers, pharmacologic thrombolysis with the drug tissue plasminogen activator (tPA), is used to dissolve the clot and unblock the artery. Another intervention for acute cerebral ischaemia is removal of the offending thrombus directly. This is accomplished by inserting a catheter into the femoral artery, directing it into the cerebral circulation, and deploying a ...

METHODS: The authors established three cohorts of Hisayama residents age ≥40 years in 1961 (1,618 subjects), 1974 (2,038 subjects), and 1988 (2,637 subjects). They followed up with each cohort for 12 years, comparing the incidence and survival rate of ischemic stroke subtypes. Morphologic examinations by autopsy or brain imaging was performed on most of the ischemic stroke cases in all cohorts. RESULTS: The age-standardized incidence of lacunar infarction significantly declined by 59% for men and by 28% for women from the first to the second cohort. It continued to ...
Translocator protein (TSPO) imaging can be used to detect neuroinflammation (including microglial activation) after acute cerebral infarction. However, longitudinal changes of TSPO binding after mild ischemia that induces selective neuronal loss (SNL) without acute infarction are not well understood. Here, we performed TSPO imaging with [18F]DPA-714 to determine the time course of neuroinflammation and SNL after mild focal ischemia. Mild focal ischemia was induced by middle cerebral artery occlusion (MCAO) for 20 min. In MCAO rats without acute infarction investigated by 2, 3, 5-triphenyltetrazolium chloride (TTC) staining, in vitro ARG revealed a significant increase of [18F]DPA-714 binding in the ipsilateral striatum compared with that in the contralateral side at 1, 2, 3, and 7 days after MCAO. Increased [18F]DPA-714 binding was observed in the cerebral cortex penumbra, reaching maximal values at 7 days after MCAO. Activation of striatal microglia and astrocytes was observed with immunohistochemistry
The NIHSS is a 15-item neurologic examination stroke scale used to evaluate the effect of acute cerebral infarction on the levels of consciousness, language, neglect, visual-field loss, extraocular movement, motor strength, ataxia, dysarthria, and sensory loss. NIHSS scores range from 0 - 42. A score of 0 indicates no stroke symptoms. Higher scores indicate incremental levels of neurological impairment ...
This is a first-in-human (FIH) study of 42037788 (referred to as CNTO 0007), a cell therapy being tested to see if it may be useful in treating patients with ischemic cerebral infarction also known as stroke. Patients will be randomized (assigned by chance) to receive a single dose of CNTO 0007 or placebo (identical in appearance to CNTO 0007 but does not contain cells) by intravenous (IV) infusion (injection directly into a vein). Patients and study staff will not know if patients are assigned CNTO 0007 or the placebo. The study will be conducted in 2 stages (Stage A and Stage B). In Stage A, the highest dose of CNTO 0007 that does not cause unacceptable side effects, referred to as the maximum tolerated dose (MTD) will be determined to and administered to patients in Stage B of the study. In Stage A, 5 (up to 7) cohorts (groups) of 4-8 patients each will be administered a single IV infusion of CNTO 0007 or placebo 1-5 days (depending on cohort) after stroke (the first cohort of patients will ...
A 64-year-old man visited our hospital with a chief complaint of appetite loss and epigastralgia. Upper GI series and an endoscopic examination revealed type 3 carcinoma on the upper third. Abdominal CT scan showed enlargement of the paraaortic lymph nodes that had invaded the pancreas. Preoperative diagnosis was cStage Ⅳ gastric cancer, and we considered a curative operation impossible. Therefore, chemotherapy with a combination therapy of 5-fluorouracil (5-FU) and low-dose cisplatin (CDDP) was planned. After 19 days of administration, the patient without vascular risk factors suddenly exhibited diplopia and left-member weakness. Brain CT showed a low- density area at the occipital lobe. Though we diagnosed cerebral infarction and treated with anti-thrombus therapy, he died of multiple cerebral infarction on day 12 of the treatrnent ...

Association between interleukin-4 genetic polymorphisms and the risk of cerebral infarction in a population of China, Hu Wei, Gao Feng, Wang Pei, Wang Gang, Zhang Yuelin
Cerebral infarction is the most common form of stroke (80% of strokes). Stroke is the first cause of acquired disability, and the 2nd cause of dementia and death. The only approved treatment in the first 4.5 hour is intravenous rt-PA thrombolysis (Actilyse ®) whose objective is recanalization of occluded artery and reperfusion of the brain parenchyma. Few patients are treated (1-5%) and they keep disability in 50-60% of cases. This handicap is mainly correlated to the final infarct size. The objective of neuroprotective treatments is to reduce the final size of the cerebral infarction. The per-conditioning remote ischemic (Per-CID) showed a neuroprotective effect in cerebral ischemia by reducing the final size of cerebral infarction animal models. The per-CID corresponds, in cases of cerebral ischemia, to iterative ischemia realization of a member with a cuff. In humans, the per-CID has shown a cardioprotective effect in a randomized control trial involving 250 patients within 6 first hours of ...
Stroke has serious implications on patients and a huge impact on society. The current treatment regimens with drug for acute cerebral infarction are unsatisfactory. Here, we explore whether the two long non-coding RNA (lncRNA) candidates from preliminary research regulate apoptosis after cerebral infarction, and evaluate the underlying mechanism of action. Bioinformatics analysis of the lncRNA microarray in the preliminary research of our group was performed. Changes in the expression of candidate lncRNAs in SH-SY5Y cells were detected by quantitative polymerase chain reaction (qPCR) after treatment with seven different oxygen and glucose deprivation (OGD) methods. The changes were detected after transfection of cells with six small-interfering RNAs (siRNAs). Cell models were established by OGD after transfection with siRNAs. Cell viability was evaluated with the cell counting kit 8 (CCK8) assay, while TUNEL staining and flow cytometry analysis were performed to determine apoptosis. Changes in ...
Background: It has been suggested that iron metabolism may be involvedin the pathogenesis of atherothrombotic cerebral infarction (ACI). The C282Y and H63D mutations in thehemochromatosis (HFE) gene are associated with increased serum iron levels and net iron accumulation.The aim of this study was to test the hypothesis that the C282Y and H63D mutations in the HFE gene arerisk factors for ACI in a Slovene population. Material/Methods: The C282Y and H63D HFE gene mutationswere tested in 96 Caucasian patients who had suffered an acute cerebral infarction, later confirmed asACI, and 115 control subjects. Genotypes were determined by electrophoresis of the DNA digestion productsfrom RsaI (C282Y) and MboI (H63D). Results: We failed to demonstrate that the C282Y and H63D mutationswere risk factors for ACI in Caucasians. The percentage of C282Y and H63D genotypes (dominant model)in ACI-cases (C282Y: 7.3%, n=7; H63D: 28.1%, n=27) did not differ significantly (P=0.9 and P=0.7 respectively)from that of ...

Large hemispheric infarction (LHI) is a severe form of stroke with high mortality and disability rates. The purpose of this study was to explore predictive indicators of the in-hospital mortality of LHI patients treated conservatively without decompressive hemicraniectomy. We performed a retrospective study of 187 consecutive patients with LHI between January 1, 2016 to May 31, 2019. The receiver operating curves were preformed to evaluate predictive performance of demographics factors, biomarkers and radiologic characteristics. Significant prognostic factors were combined to build a nomogram to predict the risk of in-hospital death of individual patients. One hundred fifty-eight patients with LHI were finally enrolled, 58 of which died. Through multivariate logistic regression analysis, we identified that independent prognostic factors for in-hospital death were age (adjusted odds ratio [aOR] = 1.066; 95% confidence interval [CI], 1.025-1.108; P = 0.001), midline shift (MLS, aOR = 1.330, 95% CI, 1.177

Top of the basilar (TOB) syndrome occurs with occlusion of the rostral portion of the basilar artery that supplies blood to the midbrain, thalamus, and temporal and occipital lobes. Symptoms associated with TOB include decreased alertness, abnormal eye movement, dysarthria, and disorders of cerebellar function. A 47-year-old man was transferred to our hospital to manage C2 vertebral fracture sustained in a traffic accident. He was alert on arrival; however, he lapsed into semicoma. He was diagnosed with TOB. Thrombolytic agents could not be administered due to a contraindication in cervical spine fracture. Brain magnetic resonance imaging showed acute infarction of the pons, cerebellum, and posterior cerebral artery territory. This rare case demonstrates that C2 vertebral fracture can result in TOB ...
Recommendations from experts and recently established guidelines on how to improve the face and predictive validity of animal models of stroke have stressed the importance of using older animals and long-term behavioral-functional endpoints rather than relying almost exclusively on acute measures of infarct volume in young animals. The objective of the present study was to determine whether we could produce occlusions in older rats with an acceptable mortality rate and then detect reliable, long-lasting functional deficits. A reversible intraluminar suture middle cerebral artery occlusion (MCAO) procedure was used to produce small infarcts in middle-aged rats. This resulted in an acceptable mortality rate, and robust disabilities were detected in functional assays, although the degree of total tissue loss measured 90 d after MCAO was quite modest. Infarcted animals were functionally impaired relative to sham control animals even 90 d after the occlusions, and when animals were subgrouped based ...
Silent brain infarction is a frequent complication of cardiac surgery and is associated with mood changes and cognitive disruption. Microsphere embolism (ME) rodent models recapitulate both the diffuse ischemic infarcts and the delayed subtle behavioral disturbances characteristic to silent infarction (SI). Previously, we have shown that ME leads to increased hippocampal inflammation, weakening of the blood brain barrier, and the infiltration of peripherally circulating inflammatory cells in rats. Given long-term increases in inflammatory activity following SI, the current study tests the efficacy of anti-inflammatory versus anti-depressant treatment strategies to reduce the inflammatory and behavioral sequelae of injury. Adult rats were administered either chronic meloxicam (preferential COX-2 inhibitor) or fluoxetine (SSRI) beginning five days prior to ME surgeries. After a two week recovery, animals were tested for anxiety-like behaviors in the open field paradigm and the hippocampus was ...

In our previous study, β-hydroxybutyrate (BHB) was found to prolong survival time and to inhibit cerebral edema by improving energy metabolism in the hypoxia, anoxia and global cerebral ischemia models. In this study, the cerebroprotective effect of BHB was examined in rats with permanent (p)-occlusion and transient (t)-occlusion of middle cerebral artery (MCA). BHB (30 mg · kg,sup,−,/sup,,sup,1,/sup, · h,sup,−,/sup,,sup,1,/sup,) was continuously administered through the femoral vein. In rats with p-MCA occlusion, BHB significantly reduced infarct area at 24 h after the occlusion, but not at 72 h after the occlusion. In rats with 2-h t-MCA occlusion followed by 22-h reperfusion, BHB significantly reduced cerebral infarct area, edema formation, lipid peroxidation and neurological deficits. Moreover, in the t-MCA occlusion model, delayed administration of BHB started at 1 h after the initiation of the MCA occlusion also significantly reduced cerebral infarct area. Taking together the ...

This is a Phase 3 study, which means that BIIB093 (study drug) has already been investigated in previous clinical research studies with a small number of people with large hemispheric infarction (LHI). These studies suggested that the study drug was safe, did not cause serious side effects or discomfort, and may reduce brain swelling, disability, and death in subjects with LHI. In this study, we want to investigate the study drug in a larger number of subjects (hundreds) to know more about it. LHI is a type of stroke. An ischemic stroke occurs when blood flow to parts of the brain is blocked, such as by a blood clot. This can cause damage to the brain. In LHI a large portion of the brain is damaged. People who have LHI can develop swelling of the brain called cerebral edema, which can worsen the symptoms and outcomes of LHI. Currently, there are no medications available to specifically reduce brain swelling caused by LHI. In this study, we want to investigate how well the study drug works to ...

Cerebrovascular diseases threaten public health, especially the aging population. Deep understanding of the features of cerebrovascular diseases can effectively assist in clinical practice. Recent studies showed that the genesis and development of cerebrovascular diseases involved in many mechanisms, e.g. inflammation, hemodynamics, dysplasia and so on. However, most of these factors will result in a degeneration of cerebral vessels and neurodegeneration, which plays an important role on genesis and development of cerebrovascular diseases. Therefore, how to diagnose and block the pathological change of degeneration of cerebral vessels could provide neurosurgeons and neurologists useful tools in the clinical practice, and provide patients an accurate treatment which could significantly improve the prognosis.This Research Topic will focus on the frontiers in the accurate treatment of cerebrovascular disease, including hemorrhagic and ischemic diseases. The goal of this Topic is to discuss the advances of
