    Full Text Available OBJECTIVE: Cerebrovascular disease is one of the important causes of seizures and epilepsy among the advanced age group. Seziures are found to be associated with lesion localization and size in previous studies. METHODS: Here, we aimed to detect prevelance of seizure, relation of seizure and lesion localization, and observed seizure types. RESULTS: Three hundred seventy eight patients with ischemic cerebrovascular disease or intraparenchymal hemorrhage who were followed in Cerrahpasa IVIedical School clinic were studied retrospectively and probability of seizure occurence within 1 month after stroke was evaluated. CONCLUSION: Among 378 patients hospitalized by acute stroke, 339 were diagnosed as ischemic cerebrovascular disease and 39 (10.3% had primary intraparenchymal hematoma. Seizures were observed in 16 patients (4.2%, 2 (%5.1 in intraparenchymal hematoma group and 14 (%4.1 in ischemic cerebrovascular disease. Early seizures were detected in 33% of patients with anterior cerebral artery, in 6.8% of posterior cerebral artery and in 3.3% of middle cerebral artery infarcts and in three patients out of 12 who were known to have epilepsy. Seizure types were secondarily generalised tonic-clonic seizure in nine cases (57%. Among whole group status epilepticus was observed in four patients (1.1%. Conclusion: Early seizure rates are found to be high among patients with anterior cerebral artery infarct and known epilepsy

  3. [Small vessel cerebrovascular disease].

    Small vessel vascular disease is a spectrum of different conditions that includes lacunar infarction, alteration of deep white matter, or microbleeds. Hypertension is the main risk factor, although the atherothrombotic lesion may be present, particularly in large-sized lacunar infarctions along with other vascular risk factors. MRI findings are characteristic and the lesions authentic biomarkers that allow differentiating the value of risk factors and defining their prognostic value. Copyright © 2018 SEH-LELHA.

  4. Migraine, cerebrovascular disease and the metabolic syndrome

    Alexandra J Sinclair

    2012-01-01

    Full Text Available Evidence is emerging that migraine is not solely a headache disorder. Observations that ischemic stroke could occur in the setting of a migraine attack, and that migraine headaches could be precipitated by cerebral ischemia, initially highlighted a possibly association between migraine and cerebrovascular disease. More recently, large population-based studies that have demonstrated that migraineurs are at increased risk of stroke outside the setting of a migraine attack have prompted the concept that migraine and cerebrovascular disease are comorbid conditions. Explanations for this association are numerous and widely debated, particularly as the comorbid association does not appear to be confined to the cerebral circulation as cardiovascular and peripheral vascular disease also appear to be comorbid with migraine. A growing body of evidence has also suggested that migraineurs are more likely to be obese, hypertensive, hyperlipidemic and have impaired insulin sensitivity, all features of the metabolic syndrome. The comorbid association between migraine and cerebrovascular disease may consequently be explained by migraineurs having the metabolic syndrome and consequently being at increased risk of cerebrovascular disease. This review will summarise the salient evidence suggesting a comorbid association between migraine, cerebrovascular disease and the metabolic syndrome.

  6. Positron emission tomography in cerebrovascular disease

    Powers, W.J.

    1988-01-01

    This paper reviews and discusses those aspects of PET that are relevant to its current and future role in the clinical care of individual patients with ischemic cerebrovascular disease. In making a judgement about the value of any diagnostic test in the management of patients with a specific disease, one must decide what criteria to apply. It is tempting to conclude that any test that provides accurate data related to the pathophysiology of the disease under consideration must be clinically useful. This is not necessarily the case, however, if the data do not lead to better patient care by reducing either morbidity and mortality or expense. Such is currently the case for PET in human cerebrovascular disease. The data that PET can provide on CBF, CBV, OEF, and CMRO 2 are accurate and are directly related to the pathophysiology of cerebral ischemia. As yet, however, there is no evidence that the application of these data leads to improvements in patient care

  7. Bacterial Endocarditis and Cerebrovascular Disease.

    Silver, Brian; Behrouz, Réza; Silliman, Scott

    2016-12-01

    Cerebrovascular complications of endocarditis occur in 25-70% of patients with infective endocarditis. The cornerstone of treatment is early initiation of antibiotic treatment, which significantly reduces the risk of embolization after 1 week of treatment. In general, thrombolysis and anticoagulation of these patients should be avoided, while antiplatelet therapy may be considered in those with other indications. Endovascular treatment of acute septic emboli is uncertain, but a few case reports have demonstrated benefit. Other complications of infective endocarditis include intracerebral hemorrhage, which may be predicted by the presence of two or more cerebral microbleeds on gradient echo sequences. Intracranial mycotic aneurysms can often be managed with serial imaging and coiled if there is evidence of failure to reduce in size, or enlargement.

    Full Text Available Although rare in childhood, stroke may have a serious impact when it happens in this stage of life. Also, it may be the first sign of a systemic disease. We report 12 cases of patients with stroke treated in the Neuropediatrics Unit of Hospital de Clínicas de Porto Alegre (HCPA from March 1997 to March 2000. All patients, from term infants to 12-year-old children hospitalized in the Pediatrics Unit of HCPA, had clinical suspicion of stroke, which was later confirmed by radiological studies. Patient follow up ranged from 1 to 6 years (mean = 3.4 years. Presenting symptoms were hemiparesis in 9 patients, seizures in 7, deviation of labial commissure in 3, and loss of consciousness in 1. The increase in the number of cases of childhood stroke identified and later confirmed by noninvasive methods had helped in the determination of different ethiologies of stroke: the most frequent being hematologic, cardiac and genetic diseases. However, our study included 6 newborns with stroke whose ethiology was not identified. Seven children with seizures received phenobarbital. Six term infants had neonatal seizures secondary to stroke and restricted to the first 72 hours of life.

    1988-01-01

    Dynamic CT was performed with 41 patients with the clinically diagnosed cerebrovascular diseases. A visual evaluation based on the dynamic CT images classified six patterns of brain parenchymal enhancement, especially four patterns of which could only be detected by dynamic CT technique. Dynamic CT was proved of great value in detecting regional cerebral tissue filled by collaterals in retrograde fashion because of the occlusion of main arteries, namely brain tissue perfusion of internal carotid occlusion disease and moyamoya disease was best understood by dynamic CT with adequate resolution.

  10. Aspirin Allergy Desensitization in Cerebrovascular Disease

    Zuckerman, Scott L; Seder, David B; Tsujiura, Crystiana; Cushing, Deborah; Gallup, Holly; Mocco, J; Hanel, Richard A; Ecker, Robert D

    2014-01-01

    Summary Aspirin (ASA) is the mainstay of treatment in cerebrovascular and systemic vascular disease. ASA hypersensitivity can pose a challenge to achieving optimum medical management prior to and after neurointerventional treatment. Desensitization to ASA is well described in the allergy and cardiovascular literature, but there are no similar discussions specific to neurointervention. The purpose of our study was to describe our experience with ASA hypersensitivity management and review the relevant literature. Two cases of patients with symptomatic cerebrovascular disease requiring neurointervention who were successfully desensitized to their ASA hypersensitivity prior to treatment are described. The subsequent literature is reviewed. Several ASA desensitization protocols exist and have been proven to successfully treat ASA hypersensitivity and allow for ASA therapy to be safely initiated. We describe several previously published protocols. ASA desensitization is a safe and simple way to manage ASA hypersensitivity. We provide comprehensive management guidelines for the neurointerventionalist engaging in ASA desensitization. PMID:24556294

  11. Coding in Stroke and Other Cerebrovascular Diseases.

    Korb, Pearce J; Jones, William

    2017-02-01

    Accurate coding is critical for clinical practice and research. Ongoing changes to diagnostic and billing codes require the clinician to stay abreast of coding updates. Payment for health care services, data sets for health services research, and reporting for medical quality improvement all require accurate administrative coding. This article provides an overview of coding principles for patients with strokes and other cerebrovascular diseases and includes an illustrative case as a review of coding principles in a patient with acute stroke.

  12. Auditory Dysfunction in Patients with Cerebrovascular Disease

    Sadaharu Tabuchi

    2014-01-01

    Full Text Available Auditory dysfunction is a common clinical symptom that can induce profound effects on the quality of life of those affected. Cerebrovascular disease (CVD is the most prevalent neurological disorder today, but it has generally been considered a rare cause of auditory dysfunction. However, a substantial proportion of patients with stroke might have auditory dysfunction that has been underestimated due to difficulties with evaluation. The present study reviews relationships between auditory dysfunction and types of CVD including cerebral infarction, intracerebral hemorrhage, subarachnoid hemorrhage, cerebrovascular malformation, moyamoya disease, and superficial siderosis. Recent advances in the etiology, anatomy, and strategies to diagnose and treat these conditions are described. The numbers of patients with CVD accompanied by auditory dysfunction will increase as the population ages. Cerebrovascular diseases often include the auditory system, resulting in various types of auditory dysfunctions, such as unilateral or bilateral deafness, cortical deafness, pure word deafness, auditory agnosia, and auditory hallucinations, some of which are subtle and can only be detected by precise psychoacoustic and electrophysiological testing. The contribution of CVD to auditory dysfunction needs to be understood because CVD can be fatal if overlooked.

  13. Arterial Spin Labeling and Blood Oxygen Level-Dependent MRI Cerebrovascular Reactivity in Cerebrovascular Disease

    Smeeing, Diederik P J; Hendrikse, Jeroen; Petersen, Esben T

    2016-01-01

    BACKGROUND: The cerebrovascular reactivity (CVR) results of blood oxygen level-dependent (BOLD) and arterial spin labeling (ASL) MRI studies performed in patients with cerebrovascular disease (steno-occlusive vascular disease or stroke) were systematically reviewed. SUMMARY: Thirty-one articles...... found a significant lower ASL CVR in the ipsilateral hemispheres of patients compared to controls. KEY MESSAGES: This review brings support for a reduced BOLD and ASL CVR in the ipsilateral hemisphere of patients with cerebrovascular disease. We suggest that future studies will be performed in a uniform...... way so reference values can be established and could be used to guide treatment decisions in patients with cerebrovascular disease....

  14. Cerebrovascular disease in Utah, 1968--1971.

    Lyon, J L; Bishop, C T; Nielsen, N S

    1981-01-01

    Utah mortality rates for cerebrovascular disease (ICD numbers 430--438) are 13% below U.S. rates. About 70% of Utahns are members of the Church of Jesus Christ of Latter-day Saints, commonly called Mormons of LDS, which proscribes use of tobacco and alcohol. Other studies on this group have found significantly lower occurrence of many cancers and ischemic heart disease. We tested the hypothesis that Utah's lower cerebrovascular disease (CBVD) mortality was contributed by the LDS population. We classified by religion all CBVD deaths (2,521) (except subarachnoid hemorrhage and cerebral embolism) occurring in the state in 1968--1971. No significant difference was found between LDS and non-LDS, but both groups had mortality rates below U.S. expectation. Although recent studies have reported smoking to be a risk factor for CBVD, we found no consistent difference between the LDS and non-LDS, even in the younger age groups. The results do not support the hypothesis that tobacco is an important etiologic agent in CBVD mortality.

  15. Radiation-induced cerebrovascular disease in children

    Wright, T.L.; Bresnan, M.J.

    1976-01-01

    Radiation-induced internal carotid artery occlusion has not been well recognized previously as a cause of childhood cerebrovascular disease. A child who had received radiation as a neonate for a hemangioma involving the left orbit at the age of 6 years experienced a recurrent right-sided paresis, vascular headaches, and speech difficulties. Angiography showed a hypoplastic left carotid artery with occlusion of both the anterior and middle cerebral arteries. Collateral vessels bypassed the occluded-stenotic segments. Review of the literature showed two additional cases of large vessel occlusion in childhood associated with anastomatic telangiectatic vessel development following early radiation therapy of facial hemangioma

    Network-sensitive neuroimaging methods have been used to characterize large-scale brain network degeneration in Alzheimer's disease and its prodrome. However, few studies have investigated the combined effect of Alzheimer's disease and cerebrovascular disease on brain network degeneration. Our study sought to examine the intrinsic functional connectivity and structural covariance network changes in 235 prodromal and clinical Alzheimer's disease patients with and without cerebrovascular disease. We focused particularly on two higher-order cognitive networks-the default mode network and the executive control network. We found divergent functional connectivity and structural covariance patterns in Alzheimer's disease patients with and without cerebrovascular disease. Alzheimer's disease patients without cerebrovascular disease, but not Alzheimer's disease patients with cerebrovascular disease, showed reductions in posterior default mode network functional connectivity. By comparison, while both groups exhibited parietal reductions in executive control network functional connectivity, only Alzheimer's disease patients with cerebrovascular disease showed increases in frontal executive control network connectivity. Importantly, these distinct executive control network changes were recapitulated in prodromal Alzheimer's disease patients with and without cerebrovascular disease. Across Alzheimer's disease patients with and without cerebrovascular disease, higher default mode network functional connectivity z-scores correlated with greater hippocampal volumes while higher executive control network functional connectivity z-scores correlated with greater white matter changes. In parallel, only Alzheimer's disease patients without cerebrovascular disease showed increased default mode network structural covariance, while only Alzheimer's disease patients with cerebrovascular disease showed increased executive control network structural covariance compared to controls.

    Full Text Available Background: Atherosclerosis is a multifactor process in which several risk factors are involved. It is the leading cause of death and morbidity in hospital admitted patients, and it may cause a marked decrease in blood flow to all organs of the body.Objective: To determine the impact of systolic hypertension on cerebrovascular disease.Methods: A cross-sectional, observational and analytical study was conducted in 59 death patients who suffered from hypertension. Cerebral arteries were analyzed and atherosclerotic lesion and its variety were quantified by using the atherometric system. The different types of hypertension were considered. Statistical (central tendency measures and comparative (comparison test based on Student’s arithmetic t-test procedures were used.Results: Recent strokes were more frequent in systodiastolic hypertensive patients. There was no significant difference in the injury onset age for both sexes, but women with systolic hypertension were significantly more damaged (from a morphometric point of view. Significant correlation for both groups of hypertensive patients was observed between type of stroke and atherometric system variables.Conclusions: Systolic hypertension is an important factor in the genesis of cerebrovascular disease and is associated with the progression of atherosclerotic plaque.

    In 131 patients with cerebrovascular disease, regional cerebral blood flow were determined by 123 I-IMP (N-isopropyl ( 123 I)-iodoamphetamine) or 99m Tc-HM-PAO ( 99m Tc (d, 1)-hexamethyl propyleneamine oxime) SPECT and findings were compared with those of X-CT or MRI. The perfusion deficit detected by SPECT was larger than the deficit by X-CT or MRI in every case. The perfusion deficit area was more clearly demonstrated by SPECT than by X-CT or MRI in patients with acute cerebral infarction. The hypoperfusion area determined by 123 I-IMP SPECT was wider than that by 99m Tc-HM-PAO SPECT. The crossed cerebellar diaschisis was observed in 56 out of 131 cases (43%). The results of operation were quantitatively evaluated by 123 I-IMP SPECT in 25 patients. (author)

    2009-01-01

    Objective: The Women's Health Initiative Memory Study (WHIMS) hormone therapy (HT) trials reported that conjugated equine estrogen (CEE) with or without medroxyprogesterone acetate (MPA) increases risk for all-cause dementia and global cognitive decline. WHIMS MRI measured subclinical cerebrovascular disease as a possible mechanism to explain cognitive decline reported in WHIMS. Methods: We contacted 2,345 women at 14 WHIMS sites; scans were completed on 1,424 (61%) and 1,403 were accepted for analysis. The primary outcome measure was total ischemic lesion volume on brain MRI. Mean duration of on-trial HT or placebo was 4 (CEE+MPA) or 5.6 years (CEE-Alone) and scans were conducted an average of 3 (CEE+MPA) or 1.4 years (CEE-Alone) post-trial termination. Cross-sectional analysis of MRI lesions was conducted; general linear models were fitted to assess treatment group differences using analysis of covariance. A (two-tailed) critical value of α = 0.05 was used. Results: In women evenly matched within trials at baseline, increased lesion volumes were significantly related to age, smoking, history of cardiovascular disease, hypertension, lower post-trial global cognition scores, and increased incident cases of on- or post-trial mild cognitive impairment or probable dementia. Mean ischemic lesion volumes were slightly larger for the CEE+MPA group vs placebo, except for the basal ganglia, but the differences were not significant. Women assigned to CEE-Alone had similar mean ischemic lesion volumes compared to placebo. Conclusions: Conjugated equine estrogen–based hormone therapy was not associated with a significant increase in ischemic brain lesion volume relative to placebo. This finding was consistent within each trial and in pooled analyses across trials.

    Thirty-four patients with cerebrovascular disease were studied with both magnetic resonance imaging (MRI) and cranial computed tomography (CT). They were 29 cerebral or cerebreller infarction and 5 cerebral bleeding. From the clinical symptoms, supratentorial lesions were suspected in 17 patients. Areas of abnormal density on CT were detected in all these patients. Areas of abnormal intensity on MRI were detected in 14 patients. Based on the infratentorial MRI, in four patients who have not shown any abnormal symptoms asyptomatic small lesions were detected. Infratentorial lesions were suspected in 17 patients. Areas of abnormal density on CT were detected in 6 patients (35%), while areas of abnormal intensity on MRI were detected in 13 patients (77%). Abnormal regions, which failed to be demonstrated on MRI were enhanced with Gd-DTPA in a patient with midbrain infarction. In a patient with Wallenberg's syndrome, area of abnormal intensity shown by MRI was consistent with lateral medullary infarct identified by autopsy. The results indicate that MRI is more useful than CT for detecting brainstem lesions in stroke. (author).

    2013-01-01

    In Spain, cerebrovascular disease (CVD) is a very common cause of morbidity and hospitalization. They are the second leading cause of mortality in the general population, and the first in women. They also constitute a very high social spending, which is estimated to increase in coming years, due to the aging of our population. Data from the Hospital Morbidity Survey of the National Statistics Institute recorded, in 2011, 116,017 strokes and 14,933 transient ischemic attacks, corresponding, respectively, to an incidence of 252 and 32 events per 100,000 people. In 2002, the cost of hospitalization for each stroke was estimated at €3,047. The amount of total cost health care throughout the life of a stroke patient is calculated at €43,129. Internationally, the direct costs of stroke constitute 3% of national health spending, this being similar amount in different countries around us. Hypertension was the cardiovascular risk factor (CVRF) more prevalent in both ischemic and hemorrhagic strokes, followed by dyslipidemia and diabetes mellitus. Peripheral arterial disease and hypertension were more frequently associated with atherothrombotic events, atrial fibrillation with cardioembolic strokes, and obesity and high blood pressure to lacunar infarcts. In Spain, as showing several studies, we are far from optimal control of CVRF, especially in secondary prevention of stroke. According to the ICTUSCARE study, achieving recommended values was 17.6% in the case of hypertension, 29.8% in LDL-cholesterol, 74.9% of smoking, and 50.2% in diabetes mellitus. In this review, we analyze in detail the epidemiology, prevention and costs originated by CVD. Copyright © 2013 Elsevier España, S.L. y SEA. All rights reserved.

    Single photon emission computed tomography(SPECT) and positron emission tomography(PET) are modern imaging techniques that allow for both qualitative are quantitative assessment of hemodynamic changes in cerebrovascular diseases. SPECT has been becoming an indispensable method to investigate regional cerebral blood flow because equipment and isotope are easily available in most general hospitals. Acetazolamide stress SPECT has also been proved to be useful to evaluate the cerebrovascular reserve of occlusive cerebrovascular diseases and to select surgical candidate. PET has gained wide spread clinical use in the evaluation of the hemodynamic and metabolic consequences of extracranial or intracranial arterial obstructive disease despite its complexity and limited availability. PET has been established as an invaluable tool in the pathophysilogy investigation of acute ischemic stroke. The potentials, limitations, and clinical applications of SPECT and PET in various cerebrovascular diseases will be discussed in this article with reviews of literatures

    En XU

    2015-01-01

    Full Text Available Cerebrovascular diseases are important causes of clinical death and disability because of high prevalence and morbidity and easy to recurrence. A number of risk factors have involved in the progress of cerebrovascular diseases, which include uncontrolled and controlled risk factors. The former refers to old age, gender, low birth weight, race/ethnicity, genetic factors, etc. The latter includes hypertension, diabetes mellitus, atrial fibrillation and other cardiac diseases, dyslipidemia, asymptomatic carotid stenosis, obesity, smoking, unhealthy lifestyle, alcoholism, metabolic syndrome, hyperhomocysteinemia, etc. Meanwhile, hypertension is the most important one in the above-mentioned risk factors. It would effectively reduce or postpone the onset of cerebrovascular diseases through proper intervention and management on those risk factors. DOI: 10.3969/j.issn.1672-6731.2015.01.006

  8. Non-invasive examination method for cerebrovascular diseases

    Chiba, Kazuo

    1979-01-01

    CT is superior in the diagnosis of the characteristics and the region of cerebrovascular diseases (CVD) to the examination with RI. The RI examination can only demonstrate the cerebrovascular diseases with large area disturbance of the cerebral cortex, that passed some days after the attack. Moreover, it is difficult to detect the small lesions or the lesions localized in the deep area such as the basal nucleus and the internal capsule by this method. A slight decrease and retardation in unilateral cerebral blood flow (under 20%, within 1.5 second) found by RI-angiography does not always indicate the side of the lesion of cerebrovascular diseases. It is expected that non-invasive examination method for CVD is improved more, and that more precise estimation method for regional cerebral circulation is developed. (Tsunoda, M.)

    Single photon emission computed tomography (SPECT) after injection of 99m-Tc-HM-PAO was used to examine 34 patients whose clinical findings could not exclude a cerebrovascular disease. In all patients an X-ray computed tomography examination was inconclusive for the clinical-neurological findings. The regional cerebral bloodflow was pathologically disturbed in 10 of 34 patients in the HM-PAO SPECT examination. The detection of the regional cerebral bloodflow with HM-PAO SPECT is helpful in the diagnosis of cerebrovascular disease. (orig.) [de

    Abstract The aim of this study is to explore whether there is a relationship between chronic pancreatitis and cerebrovascular disease in Taiwan. Using the claims data of the Taiwan National Health Insurance Program, we identified 16,672 subjects aged 20 to 84 years with a new diagnosis of chronic pancreatitis from 2000 to 2010 as the chronic pancreatitis group. We randomly selected 65,877 subjects aged 20 to 84 years without chronic pancreatitis as the nonchronic pancreatitis group. Both groups were matched by sex, age, comorbidities, and the index year of diagnosing chronic pancreatitis. The incidence of cerebrovascular disease at the end of 2011 was measured. The multivariable Cox proportional hazards regression model was used to measure the hazard ratio (HR) and 95% confidence interval (CI) for cerebrovascular disease risk associated with chronic pancreatitis and other comorbidities. The overall incidence of cerebrovascular disease was 1.24-fold greater in the chronic pancreatitis group than that in the nonchronic pancreatitis group (14.2 vs. 11.5 per 1000 person-years, 95% CI = 1.19–1.30). After controlling for confounding factors, the adjusted HR of cerebrovascular disease was 1.27 (95% CI = 1.19–1.36) for the chronic pancreatitis group as compared with the nonchronic pancreatitis group. Woman (adjusted HR = 1.41, 95% CI = 1.31–1.51), age (every 1 year, HR = 1.04, 95% CI = 1.04–1.05), atrial fibrillation (adjusted HR = 1.23, 95% CI = 1.02–1.48), chronic kidney disease (adjusted HR = 1.48, 95% CI = 1.31–1.67), chronic obstructive pulmonary disease (adjusted HR = 1.27, 95% CI = 1.16–1.40), diabetes mellitus (adjusted HR = 1.82, 95% CI = 1.72–1.92), hypertension (adjusted HR = 1.66, 95% CI = 1.56–1.76), and peripheral atherosclerosis (adjusted HR = 1.26, 95% CI = 1.06–1.51) were other factors significantly associated with cerebrovascular disease. Chronic pancreatitis is

    BACKGROUND/AIMS: To examine whether brevity can be combined with precision in measuring global cognitive ability in patients with cerebrovascular disease (CVD) or vascular dementia (VaD). Longer tests (e.g. the CAMCOG) are precise but inefficient, whereas brief tests (e.g. the MMSE) are efficient

  16. Conventional cerebral angiography in occlusive cerebrovascular disease

    Caplan, L.R.; Wolpert, S.M.

    1987-01-01

    Treatment of the patient with occlusive vascular lesions of the extracranial and intracranial arteries will depend on the location, nature, and severity of the vascular disease and the general and neurologic condition of the patient. At present, standard angiography is the best method of opacifying the vascular system to gain critical information about the vascular lesion

    While conventional angiography has been used to demonstrate cerebrovascular occlusive disease in the past, digital subtraction angiography (DSA) is capable of showing progressive vascular involvement with ease, simplicity, and extremely low morbidity, making it particularly well suited for children and outpatients either alone or coordinated with computed tomography. The authors discuss the usefulness and advantages of DSA as demonstrated in 7 infants and children with hemiplegia, 4 of whom had sickle-cell disease

    2000-01-01

    Hyperhomocysteinaemia has been identified as a risk factor for stroke and cerebrovascular disease in several studies. To evaluate the evidence we performed a meta-analysis. We found 21 studies searching Medline from 1966-July 1999 using the key words homocysteine, homocystine and cerebrovascular...... was used. The reports on 8 cross-sectional and 4 longitudinal studies gave data on the mean and standard deviations of plasma or serum homocysteine for both cases and controls, and these studies were included in the meta-analysis. The results of the 5 excluded studies all pointed to a positive relationship...

  19. Diamox-enhanced brain SPECT in cerebrovascular diseases

    Choi, Yun Young

    2007-01-01

    Acute event in cerebrovascular disease is the second most common cause of death in Korea following cancer, and it can also cause serious neurologic deficits. Understanding of perfusion status is important for clinical applications in management of patients with cerebrovascular diseases, and then the attacks of ischemic neurologic symptoms and the risk of acute events can be reduced. Therefore, the normal vascular anatomy of brain, various clinical applications of acetazolamide-enhanced brain perfusion SPECT, including meaning and role of assessment of vascular reserve in carotid stenosis before procedure, in pediatric Moyamoya disease before and after operation, in prediction of development of hyperperfusion syndrome before procedure, and in prediction of vasospasm and of prognosis in subarachnoid hemorrhage were reviewed in this paper

  20. Cerebral blood flow in sickle cell cerebrovascular disease

    Huttenlocher, P.R.; Moohr, J.W.; Johns, L.; Brown, F.D.

    1984-01-01

    Cerebral blood flow (CBF) has been studied by the xenon-133 ( 133 Xe) inhalation method in 16 children with suspected sickle cell cerebrovascular disease. Abnormalities consisting of decreases in total, hemispheral, or regional CBF were found in 17 of 26 studies. Eleven studies performed immediately after stroke, transient ischemic attack, or depression of state of alertness showed abnormalities. In addition to confirming regional cerebrovascular insufficiency in children with stroke due to major cerebral artery occlusion, the method detected diffuse decrease in CBF in children with stupor, coma, and seizures who had normal angiographic findings. In contrast, six of seven studies obtained after exchange transfusion or during maintenance on hypertransfusion therapy showed normal findings. The difference between results in patients with acute neurologic disturbances and those receiving transfusion therapy was statistically significant (P less than .005). The data indicate that the 133 Xe method reliably demonstrates cerebrovascular impairment in sickle cell disease. They also suggest that CBF changes in patients with sickle cell disease can be reversed by exchange transfusion and by hypertransfusion therapy. The 133 Xe CBF method may be useful for following up children with sickle cell disease who are at high risk for recurrent stroke

  1. Evaluating patients with ischemic cerebrovascular disease using positron emission tomography

    Raichle, M.E.

    1982-01-01

    Recent advances in nuclear medicine imaging techniques offer an important alternative for the evaluation of therapy for ischemic cerebrovascular disease. In particular, positron emission tomography (PET), with its capacity to provide quantitative measurements of brain blood flow, metabolism and biochemistry on a truly regional basis, now offers the opportunity to evaluate therapy in terms of specific changes in these parameters. By doing this PET permits one to study the problem on an individual patient basis with each subject serving as his own control. The author has been pursuing this approach in patients considered candidates for superficial temporal artery-middle cerebral artery anastomosis to bypass major stenotic or occlusive lesions of the internal carotid or middle cerebral artery. The results indicate that PET is of considerable value in establishing much more exactly the pathophysiology of certain forms of ischemic cerebrovascular disease and evaluating a form of therapy designed to correct the basic underlying defect.

    2016-09-01

    Full Text Available Endovascular therapy for ischemic cerebrovascular diseases has developed rapidly in recent years. The latest clinical trials of acute ischemic stroke have shown promising results with the continued advancement of concepts, techniques, and materials. Mechanical thrombectomy is recommended in the treatment of acute ischemic stroke caused by large vessel occlusion of the anterior circulation, according to the guidelines updated in Europe, USA, and China. The long-term therapeutic efficacy of endovascular stenting for carotid artery stenosis has also been proved noninferior to that of carotid endarterectomy. However, the latest clinical trials have shown that the efficacy of stenting for intracranial artery and vertebral artery stenosis is inferior to that of medical treatment alone, which needs urgent attention through further development and studies.

  3. The diagnosis and management of cerebrovascular disease in diabetes.

    Phipps, Michael S; Jastreboff, Ania M; Furie, Karen; Kernan, Walter N

    2012-06-01

    Cerebrovascular disease is a leading cause of morbidity and mortality in diabetes. Compared with nondiabetic patients, diabetic patients have at least twice the risk for stroke, earlier onset of symptoms, and worse functional outcomes. Approximately 20 % of diabetic patients will die from stroke, making it one of the leading causes of death in this population. Effective strategies for primary and secondary prevention of stroke have been developed in research cohorts that included both diabetic and nondiabetic patients. Nevertheless, prevention in diabetes has some specific considerations. In this paper, we summarize evidence to guide the diagnosis and management of stroke in diabetic patients. We propose that diabetic stroke patients should have a robust risk assessment to target interventions, like other patients with cerebrovascular disease, but with special attention to glycemic control and lifestyle modification.

  4. Imaging neurochemistry of cerebrovascular disease with PET and SPECT

    Hatazawa, J.; Shimosegawa, E.

    1998-01-01

    Pathophysiology od cerebrovascular disease has been studied by measuring cerebral blood flow and energy metabolism using single photon emission computed tomography (SPECT) and positron emission tomography (PET). These parameters are measures for brain tissue consisting of heterogeneous components such as neurons, glial cells, and blood vessels. It is still difficult to evaluate brain damages specifically involving either neurons or other components. Several trials were recently conducted to visualize neuron-specific injury in cerebrovascular disease by means of 11 C flumazenil for PET and 123 I-iomazenil for SPECT. These tracers selectively bind to central benzodiazepine receptor which is purely neuronal. A reduced accumulation of these ligands was found in the area surrounding the complete infarction and in the cortex remote from putaminal hemorrhage, indicating the existence of neuron specific injury not visualized by CT and MR. Neurological deficits were well correlated with the loss of cortical accumulation of these ligands. These preliminary studies indicated a potential of neurochemical imaging in cerebrovascular disease. Vulnerability to ischemia which may differ among brain tissue components, among subpopulations of neurons, and among pre-synaptic and post-synaptic functions can be more precisely examined. Neurochemical imaging can be also applied to reveal releases and re-organization of each neurotransmitter-acceptor system after stroke

  6. Clinical utility of carotid and transcranial ultrasound in cerebrovascular diseases

    Figueiredo L

    2014-08-01

    Full Text Available Lívia Figueiredo, Viviane F Zétola, Marcos C Lange Neurology Division, Hospital de Clínicas, Universidade Federal do Paraná, Curitiba, Brazil Abstract: Carotid and transcranial (CTU ultrasound is a useful tool in a number of clinical settings, particularly in cerebrovascular diseases. CTU is the only method that provides real-time determination of velocity and the spectral waveform of blood flow in the extracranial and basal intracranial arteries, and is effective in the detection of stenosis and occlusion. When transcranial ultrasound is considered, CTU is the only method that allows visualization of microembolic signals in the intracranial arteries. CTU makes a rapid differential diagnosis possible, improving therapeutic decision-making in acute stroke and determining the risk of recurrence and prognosis based on its findings. It is also the standard of care in children with sickle cell disease, when selecting patients for chronic blood transfusion, and for reducing the risk of ischemic stroke in these patients. CTU has some advantages, ie, relative simplicity in terms of interpretation and performance, and affordability, noninvasiveness, and portability. The main concern with ultrasound is that it is an operator-dependent tool and requires a high level of expertise and knowledge of three-dimensional cerebrovascular anatomy for correct interpretation of sonograms. The most significant limitation of intracranial evaluation by transcranial ultrasound is the absence of a suitable bone window in approximately 10% of patients. This paper gives an overview of the current utility and importance of CTU in the prevention and evaluation of ischemic cerebrovascular disease.

  9. Autumn Weather and Winter Increase in Cerebrovascular Disease Mortality

    McDonagh, R

    2016-11-01

    Mortality from cerebrovascular disease increases in winter but the cause is unclear. Ireland’s oceanic climate means that it infrequently experiences extremes of weather. We examined how weather patterns relate to stroke mortality in Ireland. Seasonal data for Sunshine (% of average), Rainfall (% of average) and Temperature (degrees Celsius above average) were collected for autumn (September-November) and winter (December-February) using official Irish Meteorological Office data. National cerebrovascular mortality data was obtained from Quarterly Vital Statistics. Excess winter deaths were calculated by subtracting (nadir) 3rd quarter mortality data from subsequent 1st quarter data. Data for 12 years were analysed, 2002-2014. Mean winter mortality excess was 24.7%. Winter mortality correlated with temperature (r=.60, p=0.04). Rise in winter mortality correlated strongly with the weather in the preceding autumn (Rainfall: r=-0.19 p=0.53, Temperature: r=-0.60, p=0.03, Sunshine, r=0.58, p=0.04). Winter cerebrovascular disease mortality appears higher following cool, sunny autum

    2015-01-01

    Full Text Available Background. Orthostatic hypotension (OH is an important nonmotor manifestation of Parkinson’s disease (PD. Changes in cerebrovascular reactivity may contribute to this manifestation and can be monitored using transcranial Doppler. Objective. To identify possible changes in cerebrovascular reactivity in patients with OH. Methods. Twenty-two individuals were selected and divided into three groups: with and without OH and controls. Transcranial Doppler was used to assess basal mean blood flow velocity, postapnea mean blood flow velocity, percentage increase in mean blood flow velocity, and cerebrovascular reactivity as measured by the breath-holding index. Results. PD patients had lower values of basal velocity (p=0.019, postapnea velocity (p=0.0015, percentage increase in velocity (p=0.039, and breath-holding index (p=0.04 than the controls. Patients with OH had higher values of basal velocity (p=0.09 and postapnea velocity (p=0.19 but lower values of percentage increase in velocity (p=0.22 and breath-holding index (p=0.32 than patients without OH. Conclusions. PD patients present with abnormalities in a compensatory mechanism that regulates cerebral blood flow. OH could be an indicator of these abnormalities.

    Full Text Available Chronic cerebrovascular disease (CCVD is one of the most common  iagnoses in Russian neurology, by which is meant vascular cognitive impairment (VCI in modern foreign literature. There are data available in the literature on the diagnosis and treatment of CCVD (VCI. Theresults of the author’s studies show that CCVD often masks other diseases (anxiety and depressive disorders, primary headache, peripheral vestibulopathy, and Alzheimer's disease that are unfortunately poorly diagnosed in our country, so patients do not receive effective treatment. To modify risk factors for stroke (smoking and alcohol cessation, sufficient exercise, to normalize blood pressure (the use of antihypertensivemedications, to reduce blood cholesterol levels (statins, to perform antithrombotic therapy (antiplatelet agents and anticoagulants, and to use cognitive enhancers are of key importance when treating patients with CCVD (VCI.

    1984-01-01

    Most of cerebrovascular disease are composed of vascular occulusive changes and hemorrhage. Now a day, the computed tomography is the best way for evaluation of cerebrovascular disease including detection of nature, location, and associated changes. This study includes evaluation of computed tomography of 70 patients with cerebrovascular disease during the period of 10 months from April. 1983 to Feb. 1984 in Department of Radiology, Ewha Womans University Hospital. The results were as follows: 1. Age distribution of the total 70 patients was broad ranging from 25 years to 79 years. 78.6% of patients were over the age of 50. The male and female sex ratio was 1.4:1. 2. 4 out of 70 patients were normal and 66 patients revealed abnormal on C.T. findings; those were intracranial hemorrhage (28 patients), cerebral infarction (34 patients) and brain atrophy (4 patients). 3. In cases of cerebral infarction, the cerebral hemisphere was most common site of lesion (28 cases), and next was basal ganglia (2 cases). Most of the infarcts in cerebral hemisphere were located in the parietal and temporal lobes. 4. In cases of intracranial hemorrhage, the basal ganglia was most common site of lesion (15 cases). The next common site was cerebral hemisphere (9 cases). 6 patients of all intracranial hemorrhage were combined with intraventricular hemorrhage. Ratio of right and left was 2:3. 5. In patients with motor weakness or hemiparesis, more common findings on CT scan were cerebral infarction. In case with hemiplegia, more common CT findings were intracerebral hemorrhage. 6. Of the 40 cases thought to be cerebral infarction initially by clinical findings and spinal tap. 8 cases (20.0%) were proved to be cerebral hemorrhage by the CT scan. However, of the 22 cases thought to be cerebral hemorrhage, initially, only two cases (9.0%) were cerebral infarction

  13. The Impact of Aging on Cardio and Cerebrovascular Diseases

    Carmine Izzo

    2018-02-01

    Full Text Available A growing number of evidences report that aging represents the major risk factor for the development of cardio and cerebrovascular diseases. Understanding Aging from a genetic, biochemical and physiological point of view could be helpful to design a better medical approach and to elaborate the best therapeutic strategy to adopt, without neglecting all the risk factors associated with advanced age. Of course, the better way should always be understanding risk-to-benefit ratio, maintenance of independence and reduction of symptoms. Although improvements in treatment of cardiovascular diseases in the elderly population have increased the survival rate, several studies are needed to understand the best management option to improve therapeutic outcomes. The aim of this review is to give a 360° panorama on what goes on in the fragile ecosystem of elderly, why it happens and what we can do, right now, with the tools at our disposal to slow down aging, until new discoveries on aging, cardio and cerebrovascular diseases are at hand.

  14. Helical CT scan for emergent patients with cerebrovascular diseases

    1995-01-01

    We studied 44 emergent patients with cerebrovascular diseases (18 cases of subarachnoid hemorrhage, 15 of occlusive lesions, 7 of intracerebral hematoma and 4 of suspected subarachnoid hemorrhage) using helical CT scan. The helical CT scan was performed with contrast medium at a rate of 3 ml/sec with a delay of 20 sec, and was carried out before conventional angiography. The reconstruction time of 3D-CTA was within 10 min. We were able to obtain findings for the lesion on 3D-CTA before those on conventional angiography. The 3D-CTA yielded excellent images of the vascular structures and anatomical relationships of the aneurysm, its neck and parent artery, and surrounding arteries. However, it proved difficult to visualize vessels of less than 1 mm in diameter, especially the perforating arteries. In occlusive diseases, the degree of stenosis depended on the changes in CT number threshold: at present, evaluations of the lesions should be made by conventional angiography. 3D-CTA using helical CT scan can thus be applied for emergent patients with cerebrovascular diseases. Surgical simulation images of 3D-CTA were especially useful at the time of operation. (author)

  16. Cerebral blood flow measurement in cerebrovascular occlusive diseases

    Yanagihara, T.; Wahner, H.W.

    1984-01-01

    In order to evaluate cerebral blood flow (CBF) patterns among individual patients with increased statistical confidence, CBF measurements were carried out using the 133Xe-inhalation method and external head detectors. F1 values representing gray matter flow from 3 to 6 head detectors were averaged to form 16 different regions for each cerebral hemisphere. Normative values were obtained from 46 healthy volunteers, and data from individual regions were analyzed for absolute blood flow rates (ml/100g/min), for concordance between right and left hemispheres and as percent of mean hemispheric flow. CBF measurements were then carried out among 37 patients with cerebrovascular occlusive diseases, and results were compared with normative values. A high incidence of abnormal flows were detected among symptomatic patients with intracranial arterial stenosis or occlusion and those with extracranial internal carotid artery occlusion. By using the above method for data analysis, it was possible to delineate hypoperfused areas among these patients. Even though the 133Xe-inhalation method has inherent limitations, this is a practical and safe method for measurement of CBF which can provide reliable information useful for management of patients with cerebrovascular occlusive diseases, particularly when the results are presented with statistical confidence

  17. Anton's syndrome due to cerebrovascular disease: a case report

    Maddula Mohana

    2009-09-01

    Full Text Available Abstract Introduction Anton's syndrome describes the condition in which patients deny their blindness despite objective evidence of visual loss, and moreover confabulate to support their stance. It is a rare extension of cortical blindness in which, in addition to the injury to the occipital cortex, other cortical centres are also affected, with patients typically behaving as if they were sighted. Case presentation We present a case report of an 83-year-old white woman with cortical blindness as a result of bilateral occipital lobe infarcts. Despite her obvious blindness, illustrated by her walking into objects, the patient expressed denial of visual loss and demonstrated confabulation in her accounts of her surroundings, consistent with a diagnosis of Anton's syndrome. Conclusions A suspicion of cortical blindness and Anton's syndrome should be considered in patients with atypical visual loss and evidence of occipital lobe injury. Cerebrovascular disease is the most common cause of Anton's syndrome, as in our patient. However, any condition that may result in cortical blindness can potentially lead to Anton's syndrome. Recovery of visual function will depend on the underlying aetiology, with cases due to occipital lobe infarction after cerebrovascular events being less likely to result in complete recovery. Management in these circumstances should accordingly focus on secondary prevention and rehabilitation.

    1988-02-01

    CT findings of cerebrovascular diseases were studied in 111 patients with atrial fibrillation (Af). One of these patients had cerebral hemorrhage, and another, subarachnoid hemorrhage, while the others all had cerebral infarctions. CT revealed 122 lesions with a low-density area (LDA) in 105 patients. Based on the cerebral artery territory, the 122 CT lesions were classified into the following 8 types: 10 hemispheric, 43 superficial, 23 deep, 28 superficial+deep, 1 anterior cerebral artery, 6 posterior cerebral artery, 10 watershed, and 1 vertebrobasilar. Therefore, infarctions of the internal carotid artery (ICA) system, including 94 infarctions of the middle cerebral artery territory, were most frequent, accounting for 94% of all lesions. The ratio of the left to the right infarctions of the ICA system was 1.1:1. However, it should be noted that non-embolic infarctions can occur even patients with Af.

  20. Small Vessel Cerebrovascular Disease: The Past, Present, and Future

    Réza Behrouz

    2012-01-01

    Full Text Available Brain infarction due to small vessel cerebrovascular disease (SVCD—also known as small vessel infarct (SVI or “lacunar” stroke—accounts for 20% to 25% of all ischemic strokes. Historically, SVIs have been associated with a favorable short-term prognosis. However, studies over the years have demonstrated that SVCD/SVI is perhaps a more complex and less benign phenomenon than generally presumed. The currently employed diagnostic and therapeutic strategies are based upon historical and contemporary perceptions of SVCD/SVI. What is discovered in the future will unmask the true countenance of SVCD/SVI and help furnish more accurate prognostication schemes and effective treatments for this condition. This paper is an overview of SVCD/SVI with respect to the discoveries of the past, what is known now, and what will the ongoing investigations evince in the future.

All patients underwent standard Mill and SWI, and most of them also underwent enhanced T 1 WI and MRA. The corrected phase (CP) values were obtained at the lesions and control areas. Results: The average CP values of the lesions and the control areas were -0.112±0.032 and -0.013±0.004, respectively (t=2.167, P 2 WI. The cavemoma could be differentiated from the hemorrhage within lesions. Moreover, multiple microcavernomas were detected on SWI. In 4 cases of venous hemangioma, SWI detected spider-like lesions with more hair-thin pulp veins adjacent to the dilated draining vein than contrast MRI. In 3 cases of small AVM, SWI was more advantageous than MRA in clearly detecting the small feeding artery. In 1 case of Sturge-Weber Syndrome, SWI demonstrated large areas of calcification and the abnormal vessels on the cerebral surface and the deep part of the cerebrum at the same time. In 2 cases of cerebral venous sinus thrombosis, the deep draining veins and superficial venous rete were generally dilated and winding, and the hemorrhagic lesions could be detected earlier than conventional MR images in one case. In 6 eases of cerebral infarction, old hemorrhage was clearly displayed within the lesions. Conclusion: SWI has more predominant advantages than conventional MRI and MRA in detecting the low-flow cerebral vascular malformations, identifying microbleeds and cerebral infarction accompanying hemorrhage, and the dilation of cerebral deep or superficial veins in patients with cerebral venous sinus thrombosis. Moreover, SWI can show the phase contrast between the lesions and the control areas. (authors)

  2. PET in cerebrovascular disease; PET bei zerebrovaskulaeren Erkrankungen

    Tissue viability is of particular interest in acute cerebral ischemia because it may be preserved if reperfusion can be achieved rapidly, e.g. by acute thrombolysis. Measurements of regional cerebral blood flow (CBF) and oxygen consumption by PET can assess tissue viability, and they have substantially increased our knowledge of th pathophysiology of ischemic stroke and the associated penumbra. Widerspread clinical application in acute stroke, however, is unlikely because of the large logistic and personnel resources required. In chronic cerebrovascular disease, measurement of regional CBF and glucose metabolism, which is usually coupled, provide detailed insights in disturbance of cortical function, e.g. due to deafferentiation, and contribute to differentiation of dementia types. Chronic misery perfusion, i.e. reduced perfusion that does not match the metabolic demand of the tissue, can be demonstrated by PET. It may be found in some patients with high-grade arterial stenoses. Less severe impairment of brain perfusion can be demonstrated by measurement of the cerebrovascular reserve capacity. The most frequent clinical situations can be assessed by less demanding procedures, e.g. by SPECT. In conclusion, PET has its role in cerebrovascular disease primarily within scientific studies, where high resolution and absolute quantitation of physiological variables are essential.

    CT findings in eight cerebrovascular moyamoya disease were compared with carotid angiographic findings and the results were as follows: 1. The patient's age was ranged from 2 to 49 years. Of eight patients, five were less than 17 years old and the rests were two 23 years and one 49 years of age. 2. Except one 6 years old boy, all of them were female patients. 3. In precontrast CT scan of 8 cases, 6 cases of cortical atrophy, 6 cases of ventricular dilatation and 5 cases of low density area were observed. In postcontrast study the children group shows abnormal contrast enhancement in 3 out of 5 patients but all adult reveal no contrast enhancement. 4. The isodense area in CT were thought to represent good collateral manifested by angiographic moyamoya vascular network and leptomeningeal anastomosis while the low density area in CT appears to poor colleaterals manifested by transdural anastomosis. 5. To evaluate the possibility of this disease, carotid angiography should be performed to the hemiplgic child who shows multiple low density area and abnormal enhancement in CT scan. 6. CT is not only reliable for evaluation of ventricular hemorrhage but also brain damage in patients with moyamoya disease.

    2017-01-01

    Endothelial dysfunction (ED), in particular cerebral ED, may be an essential biomarker for ischaemic cerebrovascular disease. However, there is no consensus on methods to best estimate cerebral ED. In this systematic review, we evaluate the use of l-arginine and NG -monomethyl-l-arginine (l......-NMMA) for assessment of cerebral ED. A systematic search of PubMed, EMBASE and the Cochrane Library was done. We included studies investigating cerebrovascular response to l-arginine or l-NMMA in human subjects with vascular risk factors or ischaemic cerebrovascular disease. Seven studies (315 subjects) were eligible...... cerebrovascular disease. Inconsistencies in results were most likely due to variations in methods and included subject populations. In order to use cerebral ED as a prognostic marker, further studies are required to evaluate the association to cerebrovascular disease....

    2014-12-01

    Full Text Available Background: cerebrovascular disease is the second leading cause of death in some countries, causing 10 million annual deaths. In-hospital mortality from these diseases is high in our country. Objective: to describe mortality from cerebrovascular disease at the Dr. Gustavo Aldereguía Lima University General Hospital in Cienfuegos during 2006-2010. Methods: a retrospective case series study involving all patients (4449 diagnosed with cerebrovascular disease discharged from the Dr. Gustavo Aldereguía Lima University General Hospital from January 1st, 2006 to December 31, 2010 was conducted. The variables analyzed included age, sex, status at discharge, types of cerebrovascular disease and hospital stay. Results: in-hospital mortality from cerebrovascular disease in the study period was 23.8 %. It was higher in men than in women (24.5 % and 22.9 %, respectively. According to the type of cerebrovascular disease, mortality rate of ischemic stroke was 20 %, subarachnoid hemorrhage, 22.4 % and intraparenchymal hemorrhage, 71.2 %. Conclusions: in-hospital mortality from cerebrovascular disease in Cienfuegos shows a downward trend, though it increased in 2010. It was more common in men. Death from stroke tends to decrease and, to a lesser extent, mortality due to brain hemorrhage, which remains high. There is also an increase in subarachnoid hemorrhage.

    Cerebrovascular disease (CD) and metabolic syndrome (MetS) are two devastating health dilemma that continues to be a potential contributor to disability and mortality in human population all across the world. Scientific data clearly shows several mechanistic similarities between these two co-existing and interlinked conditions. The linkage exacerbates ongoing patho-physiological condition towards more lethal events. In view of the presence of modifiable risk factors in both CD and MetS, their management holds potential therapeutic value. Hence, developing common treatment strategies for these diseases could involve common molecular agents. In this communication, we have summarized some of the common pathological conditions viz. abdominal obesity, insulin resistance, dyslipidemia, hypertension, and endothelial dysfunction that further deteriorate existing homeostasis in CD and MetS. Based on our article, it is advocated that substantial improvements in novel multi-targeted drug discovery could provide the effective treatment methods in order to avoid the fatal complications related with CD and MetS.

  9. Clinical aspects and prognosis of intraventricular hemorrhage with cerebrovascular disease

    Ikeda, Yukio; Nakazawa, Shozo; Higuchi, Hiroshi; Ueda, Kenji; Kouzo

    1982-01-01

    Intraventricular hemorrhage with cerebrovascular disease was identified in 81 cases and death occurred within seven days in 34 cases. Hypertension was the most common etiological factor, accounting for 40 of the 81 cases. Cerebral aneurysm was the second most common cause accounting for 27 cases, arteriovenous malformation accounted for 9 of the cases, and 5 were of other causes. Signs of primary or secondary brain stem dysfunction were mainly seen in cases with hypertension and aneurysm, while cases with arteriovenous malformation had benign courses. The mortality depended on the severity of intraventricular hemorrhage; i.e., the distribution, site, and the number of cast formation. The presence of intraventricular clot in the third and/or fourth ventricles was correlated with a high mortality rate, especially in cases accompanied by cast formation and third and fourth ventricular dilatation, which affects hypothalamus and brain stem function. Analysis of CT findings for the mechanism of intraventricular hemorrhage revealed three types: extension type, in which massive intracerebral hematomas extended and ruptured into ventricles; the direct type, which bled directly into ventricles without forming definite intracerebral hematomas; and the reflux type, which was characterized by reflux of the subarachnoid blood.

    Dynamic computed tomography (DCT) was evaluated as a diagnostic indicator for chronic supratentorial ischemia in 50 cases with or without minor neurological deficits. Peak height (PH, the maximum value of the gamma fitted curve), peak time (PT, the time to PH from the start of DCT), transit time (TT, the time between the first and second inflection points of the gamma fitted curve), and their functional maps were analyzed. Cerebral angiography was then performed in all cases to identify stenotic or occlusive vascular lesions in major cerebral arteries. DCT clearly detected 12 of 13 occlusions of the internal carotid artery (ICA) or middle cerebral artery (MCA), although one ICA occlusion was masked by the contralateral MCA occlusion. However, DCT detected only severe ICA or MCA stenosis (more than 90%). Probably, stenotic lesions of less than 90% did not cause detectable hemodynamic compromise. DCT using PH, PT, and TT functional maps is a useful diagnostic method for hemodynamic changes in ischemic cerebrovascular disease, althogh bilateral lesions and less stenotic lesions (<90%) are difficult to detect.

  11. The anatomy and pathophysiology of extracranial atherosclerotic cerebrovascular disease

    O'Connor, R.A.J.

    1984-01-01

    The brain is supplied by two pairs of arteries, the large carotid arteries anteriorly and the vertebral arteries (so called because they are so close to the vertebral column) posteriorly. All four arteries enter the skull at the base of the brain and are connected in the arterial circle of Willis, a unique safety device that permits arterial blood to cross from one side to the other, in case of need, or from front to back or back to front. When one inflow artery is narrowed or occluded, flow increases via other inflow arteries to maintain pressure and flow within the circle. This collateral circulation is also assisted by inflow to the circle through the orbit. When needed, arterial blood reaches the circle of Willis from the face by traversing the orbit in reverse direction. In unusual circumstances, blood in the circle of Willis can leave the brain and flow down the vertebral artery-the so-called ''vertebral steal.'' The authors provide a detailed description of the anatomy, particularly as it affects the signs, symptoms, and noninvasive diagnosis of cerebrovascular disease

    1988-01-01

    Thirty patients with acute cerebrovascular disease were evaluated by both computed tomography (CT) and magnetic resonance (MR) imaging. The 17 patients with cerebral infarction (CI) were evaluated within 24 hours and the 13 with intracerebral hemorrhage (ICH) within 6 hours of the onset of symptoms. All ICHs were detected in T2-weighted images and appeared as perifocal, ring-like areas of high signal intensity. T2-weighted images also demonstrated a ruptured aneurysm and an arteriovenous malformation. In T1-weighted images, all ICHs displayed high signal intensity, which paralleled the CT images and is characteristic of MR imaging with an ultra-low magnetic filed. These findings were obtained as early as 90 minutes from the onset of symptoms. In cases of CI, T2-weighted images obtained 3 - 7 hours after onset demonstrated the pathology more clearly than did CT. This study proved MR imaging useful in the evaluation of both ICH and CI in the acute stage. In addition, it was possible to differentiate ICH from CI in the acute stage by T2-weighted images alone.

  13. Crossed cerebellar atrophy in cases with cerebrovascular disease

    Yagishita, Toshiyuki; Kojima, Shigeyuki; Hirayama, Keizo; Iwabuchi, Sadamu.

    1989-01-01

    Crossed cerebellar atrophy (CCA) was investigated by X-ray CT to establish the incidence, mechanism, and the relation to cerebral lesions in 130 cases of unilateral supratentorial cerebrovascular diseases. The 130 cases consisted of 83 males and 47 females with cerebral infarction (65 cases) and cerebral hemorrhage (65 cases). The patients' average age was 57.6 years. Crossed cerebellar atrophy was demonstrated in 8 cases (6.2%), 6 of whom had massive cerebral infarction in the middle cerebral artery area (9.2% of the 65 cases of cerebral infarction. The six cases of CCA caused by cerebral infarction had lesions in the frontal and temporal lobes. Two had a cerebral hemorrhage in the putamen and in the thalamus, respectively, accounting for 3.1% of the 65 cases of cerebral hemorrhage. Of the 2 cases, one had putaminal hemorrhage, and the other had thalamic hemorrhage. Cerebrovascular stroke had occured in these patients with CCA more than 2 months previously. In 5 of the 8 cases of CCA, atrophy was present in the basis pedunculi and the basis pontis on the side of the cerebral lesion. However, neither dilation nor deformity of the fourth ventricle was present in any of the patients, suggesting that none of the CCA patients had atrophy of the dentate nucleus. The CCA patients had massive cerebral lesion in the frontal and temporal lobes or atrophy of the basis pedunculi and basis pontis, suggesting the presence of the transsynaptic degeneration of the cortico-ponto-cerebellar pathway. In the case of the thalamic hemorrhage, who had not hemorrhagic lesion in the frontal and temporal lobes, atrophy of the basis peduncli and basis pontis was not observed. Though dilation or deformity of the fourth ventricle is not observed in this case, presence of the degeneration of the dentate-rubro-thalamic pathway cannot be denied. CCA seems to be caused by both the transsynaptic degeneration of the cortico-ponto-cerebellar pathway and the dentate-rubro-thalamic pathway. (J.P.N.)

    2000-01-01

    To detect the clinical value of dipyridamole cerebral blood flow stress test in cerebrovascular diseases (CVD). Nineteen patients (9 male, 10 female, mean age=65) who were diagnosed as CVD were included. One suffered from infarct, two suffered from thrombosis, one feel dizziness. All 4 performed rest and stress test. The other 15 were VBI, 9 of them performed stress test. Rest and stress test were done two-day method using Elscint Apex SP-6 SPECT equipped with low energy all purpose collimator. Rest perfusion imaging was started 30 min after injecting 1.11 GBq 99m Tc-ECD. Dipyridamole stress test was done within one week. 0.56 mg/Kg dipyridamole was injected intravenously during 4 min the same dose of ECD was injected 2 min later. The acquisition started 30 min later with the same parameter. Heart rate, ECG and the patient's complaint were monitored 2 min before and after dipyridamole. After correction for attenuation, transverse, coronal and sagittal slices were reconstructed. Eighteen ROIs were drawn symmetrically on cingulate, frontal, temporal-parietal, temporal, occipital, vision cortex, basal ganglia, superior frontal and parietal on the 3 rd , 6 th , 9 th transverse slices, selecting the contralateral as the reference region. The counts per pixel in each ROI were divided by the counts of the mirror region to obtain the relative uptake ratio. We think it abnormality when the ratio is above 1,1 or below 0.9. The sensitivity for rest and stress rCBF test was compared. rCBF was decreased at 10 of 19 patients (sensitivity 52.6%). 14 had low rCBF after dipyridamole (sensitivity 72.3%), Among the patients who studied stress test, 6 had normal rCBF at rest and low rCBF after stress. The abnormal area was enlarged after dipyridamole for 1 patients, 2 improved and 2 unchanged. 8 of 15 VBI had normal rCBF at rest (sensitivity 53.3%). 9 of 15 VBI performed stress test. rCBF was normal at rest for 5 patients, rCBF was decreased after stress, it was improved for one

    Moyamoya disease is a rare steno-occlusive cerebrovascular disorder often resulting in hemorrhagic and ischemic strokes. Although sharing the same ischemic stimulus with atherosclerotic cerebrovascular disease, Moyamoya disease is characterized by a highly instable cerebrovascular system which is prone to rupture due to pathological neovascularization. To understand the molecular mechanisms underlying this instability, angiopoietin-2 gene expression was analyzed in middle cerebral artery lesions obtained from Moyamoya disease and atherosclerotic cerebrovascular disease patients. Angiopoietin-2 was significantly up-regulated in Moyamoya vessels, while serum concentrations of soluble angiopoietins were not changed. For further evaluations, cerebral endothelial cells incubated with serum from these patients in vitro were applied. In contrast to atherosclerotic cerebrovascular disease serum, Moyamoya disease serum induced an angiopoietin-2 overexpression and secretion, accompanied by loss of endothelial integrity. These effects were absent or inverse in endothelial cells of non-brain origin suggesting brain endothelium specificity. The destabilizing effects on brain endothelial cells to Moyamoya disease serum were partially suppressed by the inhibition of angiopoietin-2. Our findings define brain endothelial cells as the potential source of vessel-destabilizing factors inducing the high plasticity state and disintegration in Moyamoya disease in an autocrine manner. We also provide new insights into Moyamoya disease pathophysiology that may be helpful for preventive treatment strategies in future.

    OBJECTIVE: Cysteinyl leukotrienes are involved in inflammation and possibly in early carotid atherosclerosis. We tested the hypothesis that the -444 A/C and -1072 G/A polymorphisms of the leukotriene C(4) synthase associate with risk of ischemic cerebrovascular disease. METHODS AND RESULTS: We...... genotyped 10 592 individuals from the Danish general population, the Copenhagen City Heart Study. During 24 years of follow-up, 557 individuals developed ischemic cerebrovascular disease. The allele frequency was 0.07 for -1072 A and 0.29 for -444 C. Cumulative incidence for ischemic cerebrovascular disease...... was higher for -1072 AA versus GG genotype (log-rank: P=0.002), and lower for -444 CC versus AA genotype (log-rank: P=0.008). Combined genotypes showed corresponding cumulative incidence differences (log-rank: P=0.003). Multifactorially adjusted hazard ratios for ischemic cerebrovascular disease were 2...

    Asymptomatic extracranial artery stenosis (ECAS) is a well-known risk factor for stroke events, but it remains unclear whether it has the same role in predicting cardiovascular and cerebrovascular diseases, especially in China. We investigated the potential associations between ECAS, carotid plaque and carotid intima-media thickness and the new occurrence of cardiovascular and cerebrovascular diseases in the study. Out of 5440 study participants, 364 showed an asymptomatic ECAS at baseline, a...

    2010-08-01

    To investigate the prevalence and characteristics of cerebrovascular accidents (CVA) in a large population of adults with congenital heart disease (CHD). In a retrospective analysis of aggregated European and Canadian databases a total population of 23 153 patients with CHD was followed up to the age of 16-91 years (mean 36.4 years). Among them, 458 patients (2.0%) had one or more CVA, with an estimated event rate of 0.05% per patient-year. Permanent neurological sequelae were noted in 116 patients (25.3%). The prevalence of CVA in selected diagnostic categories was as follows: open atrial septal defect 93/2351 (4.0%); closed atrial or ventricular septal defect 57/4035 (1.4%); corrected tetralogy of Fallot 52/2196 (2.4%); Eisenmenger physiology 24/467 (5.1%); other cyanotic 50/215 (23.3%); mechanical prostheses (29/882 (3.3%). Associated conditions in patients with CVA were absence of sinus rhythm (25%), transvenous pacemakers (7%), endocarditis (2%), cardiac surgery (11%) and catheter intervention (2%), but with the exception of absent sinus rhythm these were not significantly more prevalent in patients with CVA. CVA are a major contributor to morbidity in this young population despite absence of classical cardiovascular risk factors. Although the prevalence of CVA in patients with CHD appears low, it is 10-100 times higher than expected in control populations of comparable age. Residua occur in a strong minority of patients. The subjects at highest risk are those patients with CHD with cyanotic lesions, in whom the prevalence is over 10-fold above the average.

    2003-01-01

    The purpose of this study is to present the importance of work-related cerebrovascular and heart disease from the viewpoint of expenses. Using the insurance benefit paid for the 4,300 cases, this study estimated the burden of insurance benefits spent on work-related cerebrovascular and heart disease. The number of cases with work-related cerebrovascular and heart disease per 100,000 insured workers were 3.36 in 1995; they were increased to 13.16 in 2000. By the days of occurrence, the estimated number of cases were 1,336 in 2001 (95% CI: 1,211-1,460 cases) and 1,769 in 2005 (CI: 1,610-1,931 cases). The estimated average insurance benefits paid per person with work-related cerebrovascular and heart disease was 75-19 million won for medical care benefit and 56 million won for other benefits except medical care. By considering the increase in insurance payment and average pay, the predicted insurance benefits for work-related cerebrovascular and heart disease was 107.9 billion won for the 2001 cohort and 192.4 billion won for the 2005 cohort. From an economic perspective, the results will be used as important evidence for the prevention and management of work-related cerebrovascular and heart disease. PMID:12923322

  1. Long-term exposure to ambient air pollution and mortality due to cardiovascular disease and cerebrovascular disease in Shenyang, China.

    Pengfei Zhang

    Full Text Available BACKGROUND: The relationship between ambient air pollution exposure and mortality of cardiovascular and cerebrovascular diseases in human is controversial, and there is little information about how exposures to ambient air pollution contribution to the mortality of cardiovascular and cerebrovascular diseases among Chinese. The aim of the present study was to examine whether exposure to ambient-air pollution increases the risk for cardiovascular and cerebrovascular disease. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a retrospective cohort study among humans to examine the association between compound-air pollutants [particulate matter <10 µm in aerodynamic diameter (PM(10, sulfur dioxide (SO(2 and nitrogen dioxide (NO(2] and mortality in Shenyang, China, using 12 years of data (1998-2009. Also, stratified analysis by sex, age, education, and income was conducted for cardiovascular and cerebrovascular mortality. The results showed that an increase of 10 µg/m(3 in a year average concentration of PM(10 corresponds to 55% increase in the risk of a death cardiovascular disease (hazard ratio [HR], 1.55; 95% confidence interval [CI], 1.51 to 1.60 and 49% increase in cerebrovascular disease (HR, 1.49; 95% CI, 1.45 to 1.53, respectively. The corresponding figures of adjusted HR (95%CI for a 10 µg/m(3 increase in NO(2 was 2.46 (2.31 to 2.63 for cardiovascular mortality and 2.44 (2.27 to 2.62 for cerebrovascular mortality, respectively. The effects of air pollution were more evident in female that in male, and nonsmokers and residents with BMI<18.5 were more vulnerable to outdoor air pollution. CONCLUSION/SIGNIFICANCE: Long-term exposure to ambient air pollution is associated with the death of cardiovascular and cerebrovascular diseases among Chinese populations.

    2012-01-01

    The usefulness of ambulatory, home, and casual/clinic blood pressure measurements to predict subclinical cerebrovascular diseases (silent cerebrovascular lesions and carotid atherosclerosis) was compared in a general population. Data on ambulatory, home, and casual/clinic blood pressures and brain MRI to detect silent cerebrovascular lesions were obtained in 1007 subjects aged ≥55 years in a general population of Ohasama, Japan. Of the 1007 subjects, 583 underwent evaluation of the extent of carotid atherosclerosis. Twenty-four-hour, daytime, and nighttime ambulatory and home blood pressure levels were closely associated with the risk of silent cerebrovascular lesions and carotid atherosclerosis (all Ppressure values were simultaneously included in the same regression model, each of the ambulatory blood pressure values remained a significant predictor of silent cerebrovascular lesions, whereas home blood pressure lost its predictive value. Of the ambulatory blood pressure values, nighttime blood pressure was the strongest predictor of silent cerebrovascular lesions. The home blood pressure value was more closely associated with the risk of carotid atherosclerosis than any of the ambulatory blood pressure values when home and one of the ambulatory blood pressure values were simultaneously included in the same regression model. The casual/clinic blood pressure value had no significant association with the risk of subclinical cerebrovascular diseases. Although the clinical indications for ambulatory blood pressure monitoring and home blood pressure measurements may overlap, the clinical significance of each method for predicting target organ damage may differ for different target organs.

    To investigate the relationship between cerebrovascular disease and the serum levels of homocysteine(Hcy), folate and vitamin B 12 , the serum levels of Hcy, folate and vitamin B 12 in 148 patients with cerebrovascular disease were measured by fluorescence polarization immuno- assay and chemiluminescence and were compared with those in healthy controls. The result showed that the serum Hcy levels in patients with cerebral infarction, cerebral hemorrhage and vertebrobasilar ischemiay were significantly higher than those in healthy controls (P 12 levels were signifieantly lower (P 0.05). No significantly higher ratio of increased Hcy levels was observed in patient with complications (P> 0.05). Our conclusion is that hyperhomocysteinemia may be a new and an independent risk factor for cerebrovascular disease. The serum Hcy level is correlated with decreased levels of folate and vitamin B 12 but not obviously correlated with hypertension, diabetes and coronary heart disease. (authors)

    Cerebral revascularization techniques are an indispensable tool in the current armamentarium of vascular neurosurgeons. We present revascularization surgery experience and results in both moyamoya disease and occlusive cerebral ischaemia. Patients with ischaemic occlusive disease and moyamoya disease who underwent microsurgical revascularization between October 2014 and September 2017 were analysed. In the study period, 23 patients with occlusive ischaemic disease underwent microsurgical revascularization. Three patients presented with serious postoperative complications (2 intraparenchymal haemorrhages in the immediate postoperative period and one thrombosis of the femoral artery). All patients, except one, achieved normalization of the cerebral hemodynamic reserve (CHR) in the SPECT study. Twenty patients had a good neurological result, with no ischaemic recurrence of the revascularized territory. Among patients with moyamoya, 20 had moyamoya disease and 5 had moyamoya syndrome with unilateral involvement. Five patients were treated at paediatric age. Haemorrhagic onset occurred in 2 patients. The CHR study showed hemodynamic compromise in all patients. Cerebral SPECT at one year showed resolution of the hemodynamic failure in all patients. There have been 4 postoperative complications (acute subdural hematoma, two subdural collections and one dehiscence of the surgical wound). No patient presented with neurological worsening at 6 and 12months of follow-up. Cerebral revascularization through end-to-side anastomosis between the superficial temporal artery and a cortical branch of the middle cerebral artery is an indisputable technique in the treatment of moyamoya disease and possibly in a subgroup of patients with symptomatic occlusive ischaemic cerebrovascular disease.

    Some rheumatic diseases are associated with stroke. Less is known about associations with stroke subtypes or stroke risk by age. We quantified the association between stroke, its subtypes, and rheumatic diseases and identified when stroke risk is greatest. Searches of EMBASE (from 1980) and MEDLINE (from inception) to end 2014 and manual search of reference lists for studies of stroke and stroke subtypes in rheumatic diseases as well as studies measuring cerebrovascular disease from magnetic resonance imaging. Prior published meta-analyses and new pooled analyses of any stroke in rheumatoid arthritis, systemic lupus erythematosus, ankylosing spondylitis, gout, and psoriasis show an excess risk of stroke over the general population with odds ratio (OR) ranging from 1.51 (95% confidence interval: 1.39-1.62) to 2.13 (1.53-2.98). New meta-analyses of stroke subtypes in rheumatoid arthritis [ischemic: OR, 1.64 (1.32-2.05); hemorrhagic: OR, 1.68 (1.11-2.53)] and systemic lupus erythematosus [ischemic: OR, 2.11 (1.66-2.67); hemorrhagic: OR, 1.82 (1.07-3.09)] show an excess risk of stroke over the general population. Stroke risk across rheumatic diseases is highest in those aged 65 years: OR, 1.14 (0.94-1.38); difference Pdiseases (OR, 1.3, 1.2-1.3). It was not possible to adjust ORs for risk factors or treatments. Risk of any stroke is higher in most rheumatic diseases than in the general population, particularly <50 years. Rheumatoid arthritis and systemic lupus erythematosus increase ischemic and hemorrhagic stroke risk by 60% to 100% relative to the general population. © 2016 American Heart Association, Inc.

    Objective: To explore the relationship between the dynamic changes of plasma neuropeptide (β-EP, NT, NPY) levels and the pathogenesis as well as clinical outcomes of acute cardiovascular and cerebrovascular diseases. Methods: The concentrations of serum neuropeptides (β-EP, NT, NPY) were measured on the 1 st, 3 rd, 7 th, 14 th day after the onset of disease with RIA in 103 patients with acute cardiovascular and cerebrovascular diseases (38 cases of acute cerebral infarction, 32 cases of cerebral hemorrhage, 33 cases of acute myocardial infarction and acute heart failure) and 66 controls. Results: 1. NPY, NT and β-EP levels in patients with acute cardiovascular and cerebrovascular disease were significantly higher than those in controls (p<0.01). (F=39.54, p<0.01; F=33.38, p<0.01; F=8.38, p<0.01 For β-EP, NPY and NT respectively). 2. The plasma neuropeptide levels were highest at onset and gradually lowered till to normal levels on the 14 th day. Conclusion: Plasma neuropeptide levels were closely related to the pathogenesis and clinical outcome of acute cardiovascular and cerebrovascular diseases, study of which might be useful in the clinical management of the diseases

    2002-01-01

    To study the clinical value of serum vitamin B 12 and folate in cerebrovascular disease, the concentration of serum vitamin B 12 and folate in 32 patients with cerebrovascular disease was measured by radioimmunoassay. The results showed that the changes in folate in all groups were not significant. The content of vitamin B 12 in multi-infarct dementia was markedly lower than that in cerebral infarction and cerebral hemorrhage. Moreover, the level of vitamin B 12 was lower in paralytic patients with muscular strength of grade 0-III. It can be concluded that serum vitamin B 12 level had association with intelligent disorder and paralytic degree

    1995-01-01

    We reported the usefulness of three dimensional CT angiography (3 DCTA) in cerebrovascular disease. Twenty two of twenty three intracerebral aneurysms were visualized in 3 DCTA. 3 DTPA was especially useful for the evaluation of posterior-projection anterior communicating arteries and the distinction between a carotid-posterior communicating aneurysm and an infundibular dilatation. An anterior-projection carotid bifurcation aneurysm, which we missed in DSA, was visualized clearly in 3 DCTA. Stenotic cervical carotid artery lesions were well evaluated in 3 DCTA, including ulceration. 3 DCTA was not so useful for evaluation of intracranial artery stenosis. 3 DCTA was useful as a non-invasive method to evaluate cerebrovascular diseases.

    Full Text Available James Galea,1 David Brough21Manchester Academic Health Sciences Center, Brain Injury Research Group, Clinical Sciences Building, Salford Royal Foundation Trust, Salford, UK; 2Faculty of Life Sciences, University of Manchester, AV Hill Building, Manchester, UKAbstract: Acute cerebrovascular disease can affect people at all stages of life, from neonates to the elderly, with devastating consequences. It is responsible for up to 10% of deaths worldwide, is a major cause of disability, and represents an area of real unmet clinical need. Acute cerebrovascular disease is multifactorial with many mechanisms contributing to a complex pathophysiology. One of the major processes worsening disease severity and outcome is inflammation. Pro-inflammatory cytokines of the interleukin (IL-1 family are now known to drive damaging inflammatory processes in the brain. The aim of this review is to discuss the recent literature describing the role of IL-1 in acute cerebrovascular disease and to provide an update on our current understanding of the mechanisms of IL-1 production. We also discuss the recent literature where the effects of IL-1 have been targeted in animal models, thus reviewing potential future strategies that may limit the devastating effects of acute cerebrovascular disease.Keywords: cerebral ischemia, stroke, inflammation, microglia, interleukin-1, caspase-1

    A short-term increase in dietary nitrate (NO 3 - ) improves markers of vascular health via formation of nitric oxide and other bioactive nitrogen oxides. Whether this translates into long-term vascular disease risk reduction has yet to be examined. We investigated the association of vegetable-derived nitrate intake with common carotid artery intima-media thickness (CCA-IMT), plaque severity, and ischemic cerebrovascular disease events in elderly women (n=1226). Vegetable nitrate intake, lifestyle factors, and cardiovascular disease risk factors were determined at baseline (1998). CCA-IMT and plaque severity were measured using B-mode carotid ultrasound (2001). Complete ischemic cerebrovascular disease hospitalizations or deaths (events) over 14.5 years (15 032 person-years of follow-up) were obtained from the West Australian Data Linkage System. Higher vegetable nitrate intake was associated with a lower maximum CCA-IMT (B=-0.015, P =0.002) and lower mean CCA-IMT (B=-0.012, P =0.006). This relationship remained significant after adjustment for lifestyle and cardiovascular risk factors ( P ≤0.01). Vegetable nitrate intake was not a predictor of plaque severity. In total 186 (15%) women experienced an ischemic cerebrovascular disease event. For every 1 SD (29 mg/d) higher intake of vegetable nitrate, there was an associated 17% lower risk of 14.5-year ischemic cerebrovascular disease events in both unadjusted and fully adjusted models ( P =0.02). Independent of other risk factors, higher vegetable nitrate was associated with a lower CCA-IMT and a lower risk of an ischemic cerebrovascular disease event. © 2017 American Heart Association, Inc.

    To evaluate the status and trend of direct economic burden on cerebrovascular disease, from 1993 to 2008 in China. Using two-step model to calculate the economic cost with related trend of cerebrovascular disease within the population among the over 30-year-olds, from 1993 to 2008. Data was gathered from the National Health Service Surveys Analysis Reports of 1993, 1998, 2003 and 2008, that including both direct outpatient and inpatient cost. There appeared a significant increase on the burden of cerebrovascular diseases in the period of 15 years, with direct economic cost increasing from 8.473 billion to 103.125 billion RMB. In fact, the actual increase was 5.3 times, without the influence of the price. The average annual growth rate was 13.1%, exceeding the rate of total expenditure on health and GDP during the same time span. In addition, the growth rate in 2003-2008 was the fastest, which appeared to be 19.8%. Burden that caused by cerebrovascular disease on individuals and the whole society was heavy which warrented further theoratical and practical studies on it.

    The literature on the place and role of insomnia in cerebral blood circulation disturbances is reviewed. It is emphasized that insomnia is a modifying risk factor of cerebrovascular pathology. The syndrome of obstructive sleep apnea may be a cause of arterial hypertension. The diagnostic relevance of the complex examination of patients with sleep pathology, including polysomnographic technology, and its role in the choice of corrective measures and treatment of insomnia in whole are shown.

  19. Association between Smokefree Legislation and Hospitalizations for Cardiac, Cerebrovascular and Respiratory Diseases: A Meta-Analysis

    Tan, Crystal E.; Glantz, Stanton A.

    2012-01-01

    Background Secondhand smoke causes cardiovascular and respiratory disease. Smokefree legislation is associated with a lower risk of hospitalization and death from these diseases. Methods and Results Random effects meta-analysis was conducted by law comprehensiveness to determine the relationship between smokefree legislation and hospital admission or death from cardiac, cerebrovascular, and respiratory diseases. Studies were identified using a systematic search for studies published before November 30, 2011 using Science Citation Index, Google Scholar, PubMed, and Embase and references in identified papers. Change in hospital admissions (or deaths) in the presence of a smokefree law, duration of follow-up, and law comprehensiveness (workplaces only; workplaces and restaurants; or workplaces, restaurants, and bars) were recorded. Forty-five studies of 33 smokefree laws with median follow-up of 24 months (range 2–57 months) were included. Comprehensive smokefree legislation was associated with significantly lower rates of hospital admissions (or deaths) for all 4 diagnostic groups: coronary events (RR .848, 95% CI .816–.881), other heart disease (RR .610, 95% CI .440–.847), cerebrovascular accidents (RR .840, 95% CI .753–.936), and respiratory disease (RR .760, 95% CI .682–.846). The difference in risk following comprehensive smokefree laws does not change with longer follow-up. More comprehensive laws were associated with larger changes in risk. Conclusions Smokefree legislation was associated with a lower risk of smoking-related cardiac, cerebrovascular, and respiratory diseases, with more comprehensive laws associated with greater changes in risk.

    Endothelial dysfunction (ED), in particular cerebral ED, may be an essential biomarker for ischaemic cerebrovascular disease. However, there is no consensus on methods to best estimate cerebral ED. In this systematic review, we evaluate the use of l-arginine and NG -monomethyl-l-arginine (l......-NMMA) for assessment of cerebral ED. A systematic search of PubMed, EMBASE and the Cochrane Library was done. We included studies investigating cerebrovascular response to l-arginine or l-NMMA in human subjects with vascular risk factors or ischaemic cerebrovascular disease. Seven studies (315 subjects) were eligible...... cerebrovascular disease. Inconsistencies in results were most likely due to variations in methods and included subject populations. In order to use cerebral ED as a prognostic marker, further studies are required to evaluate the association to cerebrovascular disease....

  2. Endogenous sex steroids and cardio- and cerebro-vascular disease in the postmenopausal period.

    Pappa, Theodora; Alevizaki, Maria

    2012-08-01

    Cardio- and cerebro-vascular diseases are two leading causes of death and long-term disability in postmenopausal women. The acute fall of estrogen in menopause is associated with increased cardiovascular risk. The relative contribution of androgen to this risk is also being recognized. The use of more sensitive assays for estradiol measurement and the study of receptor and carrier protein gene polymorphisms have provided some new information on the clinical relevance of endogenous sex steroids. We provide an update on the role of endogenous sex steroids on cardio- and cerebro-vascular disease in the postmenopausal period. We performed a PubMed search using the terms 'endogenous estrogen', 'androgen', 'cardiovascular disease', 'cerebro-vascular disease', 'stroke', 'carotid artery disease', and 'subclinical atherosclerosis'. The majority of studies show a beneficial effect of endogenous estrogen on the vasculature; however, there are a few studies reporting the contrary. A significant body of literature has reported associations of endogenous estrogen and androgen with early markers of atherosclerosis and metabolic parameters. Data on the relevance of endogenous sex steroids in heart disease and stroke are inconclusive. Most studies support a beneficial role of endogenous estrogens and, probably, an adverse effect of androgens in the vasculature in postmenopausal women. However, the described associations may not always be considered as causal. It is possible that circulating estrogen might represent a marker of general health status or alternatively reflect the sum of endogenous androgens aromatized in the periphery. Elucidating the role of sex steroids in cardio- and cerebro-vascular disease remains an interesting field of future research.

    2016-03-01

    Full Text Available INTRODUCTION Cardiac abnormalities are relatively common after acute neurologic injury. Disturbances can vary in severity from transient ECG abnormalities to profound myocardial injury and dysfunction. CNS is involved in the generation of cardiac arrhythmias and dysfunction even in an otherwise normal myocardium. AIM To find out proportion of ECG changes observed in ischaemic and haemorrhagic stroke. MATERIALS AND METHODS The Electrocardiographs of 100 patients with acute stroke were studied to find out the types of ECG abnormalities among different types of stroke. RESULTS In our study, the most common ECG abnormalities associated with stroke were prolonged QTc interval, ST-T segment abnormalities, prominent U wave and arrhythmias. Trop-I was positive in 12.8% patients with ECG changes. Statistical significance was found in association with Trop-I positivity and ST depression. CONCLUSION Usually patients with heart disease present with arrhythmias and Ischaemic like ECG changes. But these changes are also seen most often in the patients with presenting with stroke who didn’t have any past history of heart disease. This shows that arrhythmias and ischaemic ECG abnormalities are primarily evolved due to central nervous system disorders.

    We tried to evaluate and to compare usefulness of two brief cognitive tests in early detection of cognitive decline in subjects with increased cerebrovascular (CV) risk. As CV risk factors are recognised as important in etiology of dementia, we also aimed to determine the possible associations of specific CV risk factors and cognitive results. Patients (PGs) with first-ever stroke or TIA (N=110) and CV symptoms-free controls (CGs) with CV risk factors present (N=45) matched for age, gender and education level were tested using Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) on admission, at three- and six-month points. In all subjects, detailed CV risk factors profile was assessed. We observed the decrement in cognitive performance during the six-month study period in both groups, more evident if MoCA (pdecrement and multiple CV risk factors (>2) were found (p=0.034 for MMSE; p=0.002 for MoCA). In CGs, positive associations were found for cognitive decrement and arterial hypertension with increased IMT values (pmultiple CV risk factors and arterial hypertension (p=0.003 for MoCA). The use of MoCA could aid to early recognition of cognitive deficits in persons with increased CV risk. Individuals with multiple CV risk factors seem to have increased risk of cognitive decline.

  7. Selective intra-arterial digital subtraction angiography (IADSA) in cerebrovascular disease

    Uchino, Akira; Satoh, Yoshiyuki; Ohno, Masato

    1987-01-01

    Selective right transbrachial intra-arterial digital subtraction angiography (transbrachial selective IADSA) was successfully performed for 24 of 26 patients with known or suspected cerebrovascular disease, four of whom were outpatients. Catheterization failed in two elderly hypertensive men because of tortuosity of their brachial arteries, and in one woman whose aberrant right subclavian artery (SCA) prevented bilateral common carotid arterial (CCA) catheterizations. No complications occurred. One-hundred and ten ''excellent'' images were obtained by means of 118 injections for the 24 patients. Iopamidol, the contrast medium, was diluted to 50 % concentration with saline, then warmed to 37 deg C. Nearly all the injections of both CCAs and right vertebral arteries (VAs) were completed using 10 ml injections and a 5 ml/sec flow rate. The mean examination time for the three-vessel study was 29.4 minutes. Transbrachial selective IADSA thus proved to be a safe, useful, and relatively easy means of diagnosing cerebrovascular disease.

    Objective: This study purpose is to evaluate cerebrovascular response and reserve capacity (CVR, CVRC) by stress test with adenosine in cerebral perfusion imaging for the diagnosis of ischemic cerebrovascular diseases. Methods There were 25 patients suffered from transient ischemia attack and 16 patients suffered from occlusive cerebral artery in this study. The rest cerebral perfusion imaging was obtained 30 minutes post-injection of 99mTC-ethylene cysteinate dimmer. After 2-5 days, adenosine stress tests were performed. Adenosine (0.14 mg/kg min) was administered intravenously 3 minutes pre-injection of 99mTC-ECD.Under same condition, the rest and stress tests of cerebral perfusion imaging were performed. By visual and semiquantitative analysis, the results of the rest/stress imaging were divided into the following four patterns: A: The stress imaging showed an expand areas of hypoperfusion, asymmetry index (AI) was decreased; B: Rest imaging was normal but new hypoperfused areas appeared with AI index declining in stress test; C: The hypoperfused areas were decreased or disappeared in size with AI index increasing in stress test; D: No changes showed in cerebral perfusion imaging patterns and Al index between rest and stress tests. AI index was ratio of radio account of interest regions than average radio account of cerebella. Results It was found that A, B, C and D type were 24%,12%,56% and 8% respectively in the group of transient ischemia attack patients, and 31%,44%, 19% and 6% respectively in the group of occlusive cerebrovascular patients. In rest test, of 41 patients of cerebrovascular disease, there were 28 cases decreased of radio uptake, moreover in stress test, there were 38 case decreased of radio uptake, positive rate were 68.29% and 92.68% respectively. Compared to X±SD of AI index of rest/stress test, it is found to increasing and being significant statistics (p<0.01, Spass 8.0 statistics software). Conclusion: Adenosinal-induced vasodilatation

    We aimed to analyze the impact of drinking and smoking behavior on the risk of developing cerebrovascular diseases among male employees aged 20-46 years. Twenty years of follow-up data of male employees enrolled in the DENSO Health Insurance Program were used for analyses. Of 29,048 male employees aged 20-46 years who were enrolled in the insurance program in 1994, 25,084 (86.4%) employees underwent annual health check-ups until 2003 without missing an appointment. Of these 25,084 employees, the data of 11,784 (40.6%) employees who self-reported drinking and smoking habits were used for analyses. The hazard ratio and 95% confidence intervals (CIs) for developing cerebrovascular disease in 2004-2013 were calculated in four risk groups categorized as per drinking and smoking behavior in the young group who were in their 20s and the middle-aged group who were in their 30s-40s in 1994. Based on their drinking behavior, participants were categorized into two groups: "not drinking or drinking sometimes" and "drinking every day." Based on their smoking behavior, participants were also categorized into two groups: "not smoking for 10 years" and "smoking for 10 years." A Cox's proportional hazard model revealed that after controlling for body mass index, systolic blood pressure, triglycerides, total cholesterol, fasting plasma glucose, and age, the hazard ratios for "smoking and drinking every day" were 3.82 (95% CI: 1.40-10.41) in the young group and 2.31 (95% CI: 1.27-4.17) in the middle-aged group. Male employees who had been drinking and smoking for 10 years had a higher risk of developing cerebrovascular diseases. To prevent cerebrovascular diseases among male employees, it may be effective to offer behavior change interventions for both drinking and smoking habits, regardless of the age group.

    Cerebrovascular accidents, or strokes, are the second leading cause of mortality and the leading cause of morbidity in both Chile and the rest of the world. However, the relationship between particulate matter pollution and strokes is not well characterized. The association between fine particle concentration and stroke admissions was studied. Data on hospital admissions due to cerebrovascular accidents were collected from the Ministry of Health. Air quality and meteorological data were taken from the Air Quality database of the Santiago Metropolitan Area. Santiago reported 33,624 stroke admissions between January 1, 2002 and December 30, 2006. PM2.5 concentration was markedly seasonal, increasing during the winter. This study found an association between PM2.5 exposure and hospital admissions for stroke; for every PM2.5 concentration increase of 10 μg m −3 , the risk of emergency hospital admissions for cerebrovascular causes increased by 1.29% (95% CI 0.552%–2.03%). Highlights: •Particulate matter pollution – cerebrovascular diseases relationship is not well known. •Cerebrovascular diseases are the second leading cause of mortality and the leading cause of morbidity. •PM2.5 increase 10 μg/m 3 the risk of hospital admissions for stroke causes increases by 1.29%. •The results are similar to that of other cities worldwide. -- Relationship between PM pollution and strokes is not well characterized. In Santiago the risk of the stroke increased by 1.29%; for every increase of 10 μg m −3 in PM2.5

    Full Text Available Abstract Background: Cerebrovascular and hypertensive diseases are among the main causes of death worldwide. However, there are limited data about the trends of these diseases over the years. Objective: To evaluate the temporal trends in mortality rates and proportional mortality from cerebrovascular and hypertensive diseases according to sex and age in Brazil between 1980 and 2012. Methods: We evaluated the underlying causes of death between 1980 and 2012 in both sexes and by age groups for circulatory diseases (CD, cerebrovascular diseases (CBVD, and hypertensive diseases (HD. We also evaluated death due to all causes (AC, external causes (EC, and ill-defined causes of death (IDCD. Data on deaths and population were obtained from the Department of Information Technology of the Unified Health System (Departamento de Informática do Sistema Único de Saúde, DATASUS/MS. We estimated crude and standardized annual mortality rates per 100,000 inhabitants and percentages of proportional mortality rates. Results: With the exception of EC, the mortality rates per 100,000 inhabitants of all other diseases increased with age. The proportional mortality of CD, CBVD, and HD increased up to the age range of 60-69 years in men and 70-79 years in women, and reached a plateau in both sexes after that. The standardized rates of CD and CBVD declined in both sexes. However, the HD rates showed the opposite trend and increased mildly during the study period. Conclusion: Despite the decline in standardized mortality rates due to CD and CBVD, there was an increase in deaths due to HD, which could be related to factors associated with the completion of the death certificates, decline in IDCD rates, and increase in the prevalence of hypertension.

    Kokubo, Yasuaki; Kayama, Takamasa; Kondo, Rei; Oki, Masato; Takaoka, Seiji

    2008-01-01

    Whenever we discuss the overall results of surgical treatment for unruptured cerebral aneurysms, especially in aged patients, we tend to consider advanced age or general anesthesia as causes for unfavorable results. There are no reports concerning ischemic stroke events following general anesthesia in aged patients with a prior history of cerebrovascular disease. The purpose of this study is to clarify the influence of general anesthesia on the brats in aged patients with a previous history of ischemic cerebrovascular disease. The subjects were 30 consecutive patients over 70 years of age with previous ischemic cerebrovascular disease who underwent various surgeries except brain and cardiac surgery under general anesthesia. The patients were 70 to 85 years old, with a mean age of 76. Twenty-three were men and 7 were women. Surgical procedures were 12 gastrointestinal, 6 orthopedic and 4 urogenital and others. The type of cerebrovascular disease evaluated by neuroradiologist and anesthesiologist based on MR imaging was devided as follows: 16 patients had minor stroke, 7 had transient ischemic attack/reversible ischemic neurological deficit (TIA/RIND) and 7 had asymptomatic cerebral infarction. MR angiography was also assessed to evaluate the main artery in the brain. Blood pressure and arterial blood gas (PaCO 2 ) during general anesthesia were analyzed, and the rate of systemic and neurological complications following general anesthesia were evaluated. MR angiography revealed no occlusion or severe stenosis of the main artery in the brain of any of the patients. The minimum systolic blood pressure showed less than 100 mmHg transiently for 5-20 minutes in 28 of 30 patients during general anesthesia. The minimum value was 65 mmHg maintained for 5 minutes. The minimum PaCO 2 during general anesthesia was as follows: 1 case 36 mmHg. There were no neurological complications following general anesthesia in this study. One of 30 patients (3.3%) had suffered from pneumonia

    Full Text Available

    Moyamoya disease is a very rare chronic cerebrovascular disease of unknown etiology characterized by recurrent ischemic or hemorrhagic strokes. Initially diagnosed in Japan and named after finding puff of smoke like collateral blood vessels around the occluded blood vessels of circle of Willis. With increase awareness this disease is now diagnosed more often. Medical and surgical treatment have been used to treat the disease, with surgical treatment been mostly experimental. Special attention should be given to the surgical treatment which has shown to have an edge over the medical treatment in some clinical trials especially in young patients with recurrent strokes to prevent progressive cognitive decline and to improve their quality of life. In our patient, who is a young man, the diagnosis was picked up late and when surgical evaluation was performed, it was considered to be fruitless with findings of nonviable brain tissue on MRI imaging.

    2017-08-01

    Small studies have suggested that Ehlers-Danlos syndrome (EDS) is associated with a number of cerebrovascular complications. We sought to determine whether a clinical diagnosis of EDS is associated with a higher prevalence of cerebrovascular diseases than the general population by performing a case-control study of hospitalized patients in the Nationwide Inpatient Sample (NIS). Using the 2000-2012 NIS, we performed a case-control study matching cases of EDS to controls without such a diagnosis. The prevalence of various cerebrovascular diseases between the 2 groups was compared, and multivariate logistic regression was used to adjust for suspected comorbidities. Between 2000 and 2012, there were a total of 9067 discharges carrying a diagnosis of EDS. On univariate analysis, patients with EDS were more likely to be hospitalized for carotid dissection (.2% versus .01%, odds ratio [OR] = 18.0, confidence interval [CI] = 2.41-135.12, P < .0001), vertebral dissection (.1% versus 0%, P = .008), cervical artery aneurysm (.1% versus .01%, OR = 9.01, CI = 1.14-71.11, P < .0001), cerebral aneurysm (.4% versus .09%, OR = 4.89, CI = 2.28-10.47, P < .0001), and cerebrovascular malformation (.1% versus .02%, OR = 5, CI = 1.10-22.85, P = .021), compared to the controls. On multivariate analysis adjusted for age, race, and comorbidities, EDS patients had significantly higher odds of carotid dissection (OR = 15.02, CI = 3.08-270.87, P < .0001), vertebral dissection (OR = 2406539.5, P = .0037), cervical artery aneurysm (OR = 11.75, CI = 2.11-220.71, P = .0026), cerebral aneurysm (OR = 5.59, CI = 2.69-13.18, P < .0001), and cerebrovascular malformation (OR = 4.67, CI = 1.20-30.87, P = .0243). Carotid and vertebral dissections, cervical and cerebral aneurysms, as well as other cerebrovascular malformations are more common in hospitalized patients with EDS compared to controls

    To explore temporal trends, geographic distribution, and socioeconomic determinants of scientific production in the field of cerebrovascular and cardiovascular disease (CCD) rehabilitation. Citations from 1967 to 2008 were downloaded from the PubMed database. Core of the search strategy was the key word cardiovascular diseases in the Medical Subject Headings major field with the subheading rehabilitation. Journal Citation Reports was used to assign an impact factor (IF). Demographic and economic data were retrieved from the International Monetary Fund. All articles retrieved were included in the bibliometric analysis. The search strategy was validated on a random sample of the articles retrieved. The search quality reflected the level of error of the PubMed database. Publications retrieved were 10,379 and have grown 8.6 times in 40 years, faster than the all-diseases rehabilitation field (7.8 times), with a particularly steep growth for cerebrovascular diseases in the last 15 years (5 times). However, in the last decade, the articles' quality (IF) decreased. From 1994 to 2008, 3466 citations were retrieved; 44.4% came from the European Union and 30.3% from the United States. The highest mean IF was reported for France (4.127). The United Kingdom and some relatively small northern European Union countries had the best ratio of IF (sum) to resident population or to gross domestic product. The most frequently used key word was stroke, and 3 journals (Archives of Physical Medicine and Rehabilitation, Clinical Rehabilitation, and Stroke) published one quarter of the articles. The overall scientific production in the field of CCD rehabilitation showed a steep growth in the last decade, especially because of cerebrovascular research. In the same period, a decrease in the overall IF was observed. The European Union and the United States contributed 3 of every 4 articles in the field, although some Asian countries showed promising performance. Copyright © 2013 American

    Hirata, Yoshifumi; Nonaka, Nobuhito; Matsukado, Yasuhiko; Takahashi, Mutsumasa

    1987-09-01

    Dynamic intravenous digital subtraction angiography (IV-DSA) was performed in 37 patients with cerebrovascular ischemic diseases. The time density curve of IV-DSA was analysed, and peak time, mean transit time and mode of transit time were obtained in each patient. On the basis of these values, cerebral perfusion was classified into low, normal and high perfusion patterns. Normal perfusion pattern was noted in 40% of patients with transient ischemic attack (TIA) and 7 % of patients with cerebral infarction. Low perfusion pattern was observed in 60 % of patients with TIA and 87 % of patients with cerebral infarction. High perfusion pattern was encountered only in 7 % of patients with cerebral infarction. In ischemic patients with moyamoya disease, extremely prolonged cerebral circulation time was evidenced by the presence of a flat or uphill type of the time density curve. This finding well correlated with decreased cerebral blood flow on single photon emission tomography. These findings suggest that the analysis of dynamic DSA is very important and useful in the clinical evaluation of patients with cerebrovascular ischemic diseases.

    1984-01-01

    Coronary artery disease is the cause of death in most patients who have transient ischemic attacks or stroke. Evaluation for this condition is not routinely performed in such patients, and no prospective studies have been reported. We prospectively examined 50 consecutive patients with transient ischemic attacks or mild stroke to determine the prevalence and importance of coronary artery disease. All patients were examined by a cardiologist and underwent both exercise thallium-201 scintigraphy and exercise radionuclide ventriculography. Sixteen patients were suspected to have coronary artery disease on the basis of clinical evaluation. In 15 of these the was confirmed by the nuclear scans. The remaining 34 patients had no clinical evidence of heart disease, yet 14 had abnormal cardiac scans. Twenty of 22 patients with abnormal scans who underwent cardiac catheterization had significant coronary artery disease or a cardiomyopathy. The discovery of heart disease altered clinical management in 13 patients. Overall, 29 of 50 patients had significant coronary artery disease, compared with a 7% prevalence of the condition in other patients of similar age at the same institution

    Full Text Available This study searches the National Health Insurance Research Database (NHIRD used in a previous project, aiming for reconstructing possible cerebrovascular disease-related groups (DRG,and estimating the costs between cerebrovascular disease and related diseases.We conducted a nationwide retrospective cohort study in stroke inpatients, we examined the overall costs in 3 municipalities in Taiwan, by evaluating the possible costs of the expecting diagnosis related group (DRG by using the international classification of diseases version-9 (ICD-9 system, and the overall analysis of the re-admission population that received traditional Chinese medicine (TCM treatment and those who did not.The trend demonstrated that the non-participant costs were consistent with the ICD-9 categories (430 to 437 because similarities existed between years 2006 to 2007. Among the TCM patients, a wide variation and additional costs were found compared to non-TCM patients during these 2 years. The average re-admission duration was significantly shorter for TCM patients, especially those initially diagnosed with ICD 434 during the first admission. In addition, TCM patients demonstrated more severe general symptoms, which incurred high conventional treatment costs, and could result in re-admission for numerous reasons. However, in Disease 7 of ICD-9 category, representing the circulatory system was most prevalent in non-TCM inpatients, which was the leading cause of re-admission.We concluded that favorable circulatory system outcomes were in adjuvant TCM treatment inpatients, there were less re-admission for circulatory system events and a two-third reduction of re-admission within ICD-9 code 430 to 437, compared to non-TCM ones. However, there were shorter re-admission duration other than circulatory system events by means of unfavorable baseline condition.

  4. Possibilities of using naftidrofuryl in the therapy of cerebrovascular diseases: Literature review and the authors’ observations

    A. N. Belova

    2015-01-01

    Full Text Available The efficacy of naftidrofuryl in treating cerebrovascular diseases is analyzed on the basis of a review of the Russian and foreign literature. Naftidrofuryl is a seroton 5-HT2 receptor antagonist and acts on brain energy metabolism mainly during hypoxia or ischemia. The results of preclinical studies proving the antispasmodic and neuroprotective properties of the drug and its capacity to normalize microcirculation in hypoxia are briefly considered. Experimental findings served as a basis for further studies of the efficacy of naftidrofuryl in patients with stroke, chronic cerebral ischemia, or vascular dementia. The use of naftidrofuryl (dusopharm was demonstrated to statistically significantly enhance the efficiency of rehabilitation in post-stroke patients and to be followed by significant psychoemotional improvement. According to a Cochrane review, the naftidrofuryl-treated patients with vascular dementia showed a tendency towards better executive and cognitive functions, behavior, and mood. The drug was noted to have a positive effect on the health of patients with chronic cerebral ischemia.The authors provide the data of their trial of naftidrofuryl used in patients with dyscirculatory encephalopathy, which have confirmed its efficacy in this category of patients. The data available in the literature suggest that oral naftidrofuryl has a good tolerability and safety profile in patients with cerebrovascular diseases.

    2004-01-01

    Objective: To investigate the inter-relationship among serum leptin insulin resistance and blood lipids, and to explore the role of leptin in the pathogenesis of ischemic cerebrovascular diseases (ICVD). Methods: Levels of serum leptin, insulin and blood lipids were determined with RIA in 131 patients with different types of ICVD and 36 controls. Results: The levels of serum leptin in ICVD patients were significantly higher than those in the controls (P<0.01). Changes of blood lipids and insulin paralleled those of leptin (cxcept with HDL-C). The serum leptin were positively correlated to cholesterol, TG and insulin levels (r=0.45, P<0.05; r=0.31, P<0.05, r=0.55, P<0.01), but negatively correlated to HDL-C (r=-0.88, P<0.05). Conclusion: The high expression of leptin in ICVD patients is associated with high lipid and insulin levels. The close relationship among them indicates that high leptin levels play an important role in the pathogenesis of metabolic syndrome as well as atheromatous cerebrovascular diseases. (authors)

    2010-01-01

    Objective: To investigate the relationship between oxygen free radicals, cytokines, cortisol and stress complications in patients with acute cerebrovascular disease (ACVD). Methods: Serum levels of superoxide dismutases (SOD), malonaldehyde (MDA) (with biochemistry) interleukin-6 (IL-6), tumor necrosis factor (TNF-α) and cortisol (with RIA) were measured in 32 patients with acute cerebrovascular disease (ACVD) plus stress complications and 48 patients without stress complications as well as 36 controls. Results: Serum SOD contents in non-stressed group were higher than those in stressed group (P<0.05) but lower than those of the controls (P<0.05). However the levels of MDA, IL-6, TNF-α and cortisol were highest in the stressed group and lowest in the controls (all P<0.05). Conclusion: Oxygen free radicals, IL-6, TNF-α and cortisol were involved in stress complications in patients with ACVD. Monitoring the levels of serum SOD, MDA, IL-6, TNF-α and cortisol could be useful for predicting stress complications and evaluating the therapeutic effect. (authors)

    2018-01-08

    There is little control of cardiovascular (CV) risk factors in secondary prevention after an ischaemic stroke, in part due to a lack of adherence to treatment. The CV polypill may contribute to proper treatment adherence, which is necessary for CV disease prevention. This study aimed to establish how and in what cases the CV polypill should be administered. A group of 8 neurologists drafted consensus recommendations using structured brainstorming and based on their experience and a literature review. These recommendations are based on the opinion of the participating experts. The use of the CV polypill is beneficial for patients, healthcare professionals, and the health system. Its use is most appropriate for atherothrombotic stroke, lacunar stroke, stroke associated with cognitive impairment, cryptogenic stroke with CV risk factors, and silent cerebrovascular disease. It is the preferred treatment in cases of suspected poor adherence, polymedicated patients, elderly people, patients with polyvascular disease or severe atherothrombosis, young patients in active work, and patients who express a preference for the CV polypill. Administration options include switching from individual drugs to the CV polypill, starting treatment with the CV polypill in the acute phase in particular cases, use in patients receiving another statin or an angiotensin ii receptor antagonist, or de novo use if there is suspicion of poor adherence. Nevertheless, use of the CV polypill requires follow-up on the achievement of the therapeutic objectives to make dose adjustments. This document is the first to establish recommendations for the use of the CV polypill in cerebrovascular disease, beyond its advantages in terms of treatment adherence.

  8. Pioglitazone improves reversal learning and exerts mixed cerebrovascular effects in a mouse model of Alzheimer's disease with combined amyloid-β and cerebrovascular pathology.

    Panayiota Papadopoulos

    Full Text Available Animal models of Alzheimer's disease (AD are invaluable in dissecting the pathogenic mechanisms and assessing the efficacy of potential new therapies. Here, we used the peroxisome proliferator-activated receptor gamma agonist pioglitazone in an attempt to rescue the pathogenic phenotype in adult (12 months and aged (>18 months bitransgenic A/T mice that overexpress a mutated human amyloid precursor protein (APPSwe,Ind and a constitutively active form of transforming growth factor-β1 (TGF-β1. A/T mice recapitulate the AD-related cognitive deficits, amyloid beta (Aβ and cerebrovascular pathologies, as well as the altered metabolic and vascular coupling responses to increased neuronal activity. Pioglitazone normalized neurometabolic and neurovascular coupling responses to sensory stimulation, and reduced cortical astroglial and hippocampal microglial activation in both age groups. Spatial learning and memory deficits in the Morris water maze were not rescued by pioglitazone, but reversal learning was improved in the adult cohort notwithstanding a progressing Aβ pathology. While pioglitazone preserved the constitutive nitric oxide synthesis in the vessel wall, it unexpectedly failed to restore cerebrovascular reactivity in A/T mice and even exacerbated the dilatory deficits. These data demonstrate pioglitazone's efficacy on selective AD hallmarks in a complex AD mouse model of comorbid amyloidosis and cerebrovascular pathology. They further suggest a potential benefit of pioglitazone in managing neuroinflammation, cerebral perfusion and glucose metabolism in AD patients devoid of cerebrovascular pathology.

    BACKGROUND: Diabetes mellitus is one of the risk factors in patients with acute cerebral disease, and always leads to stroke or get it worse. There is often a high level of blood glucose in those patients with diabetes mellitus and cerebral disease, but it is hard to distinguish from both kinds of hyperglycemia. Serum fructosamine is said to be correlated with blood glucose.OBJECTIVE: To explore the relationship between serum fructosamine and blood glucose in patients with acute cerebrovascular disease.DESTGN: A case-controlled study.SETTINGS: Department of Clinical Laboratory, Health Department for Cadres and Department of Neurology of Affiliated Hospital, Qingdao University Medical College.PARTICIPANTS: Forty-eight inpatients and outpatients with cerebrovascular diseases were selected from the Department of Neurology, Affiliated Hospital of Qingdao University Medical College from December 2004 to April 2005. All the patients were confirmed with CT and MRI. There were 25 patients with diabetes mellitus secondary cerebrovascular diseases, who met the diagnostic standards of diabetes mellitus set by WHO,including 12 males and 13 females with an average of (60±8) years old, the course of diabetes mellitus ranged from 1 to 21 years.. The other 23 patients had no diabetes mellitus (without diabetes mellitus group), including 14 males and 9 females with an average of (62±6) years old. Meanwhile, another 50 healthy physical examinees in the hospital were selected as control group, including 26 males and 24 females with the average age of (62±5) years old. Informed content was obtained from all the participants.METHODS: Venous blood was drawn from all the participants, and content of blood glucose was assayed by means of glucose oxidase, and the concentration of serum fructosamine was determined by nitroblue tetrazolium colorimetric method. Comparison between groups was performed by the analysis of variance and q test, and the correlation was tested by linear

    Findings from the Nun Study indicate that low linguistic ability in early life has a strong association with dementia and premature death in late life. In the present study, we investigated the relationship of linguistic ability in early life to the neuropathology of Alzheimer's disease and cerebrovascular disease. The analyses were done on a subset of 74 participants in the Nun Study for whom we had handwritten autobiographies completed some time between the ages of 19 and 37 (mean = 23 years). An average of 62 years after writing the autobiographies, when the participants were 78 to 97 years old, they died and their brains were removed for our neuropathologic studies. Linguistic ability in early life was measured by the idea (proposition) density of the autobiographies, i.e., a standard measure of the content of ideas in text samples. Idea density scores from early life had strong inverse correlations with the severity of Alzheimer's disease pathology in the neocortex: Correlations between idea density scores and neurofibrillary tangle counts were -0.59 for the frontal lobe, -0.48 for the temporal lobe, and -0.49 for the parietal lobe (all p values < 0.0001). Idea density scores were unrelated to the severity of atherosclerosis of the major arteries at the base of the brain and to the presence of lacunar and large brain infarcts. Low linguistic ability in early life may reflect suboptimal neurological and cognitive development, which might increase susceptibility to the development of Alzheimer's disease pathology in late life.

    As the human population continues to age, an increasing number of people will exhibit significant deficits in cognitive function and dementia. It is now recognized that cerebrovascular, metabolic and neurodegenerative diseases all play major roles in the evolution of cognitive impairment and dementia. Thus with our more recent recognition of these relationships and our need to understand and more positively impact on this world health problem, "The Leo and Anne Albert Charitable Trust" (Gene Pranzo, Trustee with significant support from Susan Brogan, Meeting Planner) provided generous support for this inaugural international workshop that was held from April 13-16, 2015 at the beautiful Ritz Carlton Golf Resort in North Naples, Florida. Researchers from SUNY Downstate Medical Center, Brooklyn, NY organized the event by selecting the present group of translationally inclined preclinical, clinical and population scientists focused on cerebrovascular disease (CVD) risk and its progression to vascular cognitive impairment (VCI) and dementia. Participants at the workshop addressed important issues related to aging, cognition and dementia by: (1) sharing new data, information and perspectives that intersect vascular, metabolic and neurodegenerative diseases, (2) discussing gaps in translating population risk, clinical and preclinical information to the progression of cognitive loss, and (3) debating new approaches and methods to fill these gaps that can translate into future therapeutic interventions. Participants agreed on topics for group discussion prior to the meeting and focused on specific translational goals that included promoting better understanding of dementia mechanisms, the identification of potential therapeutic targets for intervention, and discussed/debated the potential utility of diagnostic/prognostic markers. Below summarizes the new data-presentations, concepts, novel directions and specific discussion topics addressed by this international

    Full Text Available Background: There are a growing number of studies suggesting that depression may increase the risk of stroke. Impaired autoregulation of vascular tone may contribute to a higher risk of developing cerebrovascular diseases. Cerebrovascular reactivity (CVR reflects the compensatory dilatory capacity of cerebral arterioles to a dilatory stimulus and is an important mechanism that ensures constant cerebral blood flow. There is a hypothesis that CVR is reduced in major depression, which would explain the association between depression and stroke. Objectives: The aim of this study was to investigate the effect of depression on CVR in cerebral vessels by comparing CVR during the depression phase with that during remission. Material and Methods: Using the apnea test, we assessed CVR in 16 patients with unipolar depression during disease and after remission of disease by calculating the increase in cerebral blood flow velocity after breath-holding (the apnea test. Blood flow velocities were measured by transcranial Doppler ultrasound (TCD. Results: CVR was significantly reduced in the depression phase in comparison to that in the remission phase. However, this change was not seen in all the patients. Conclusion: CVR was reduced in most of the depressed patients. The decreased CVR, as indicated by the changes in peak systolic velocity (PSV and mean flow velocity (MFV of the middle cerebral artery, in depressed patients was more marked on the right side, which could point to a vascular basis for some kinds of depression. We recommend that other studies, with larger samples, be done; future studies should assess whether the changes in the CVR varies with the severity and type of depression.

    Full Text Available Aim: organization and follow-up of a registry of patients with cerebrovascular disease in in special department. Materials and methods. In the period from January 2011 to December 2013 all cases of cerebrovascular disease in the special department were recorded. Each patient had an electronic case book and thematic record, developed on the basis of the materials of the National Stoke Association of "Registry of stroke." Results. 418 cases of cerebral stroke were registered. Male to female ratio was 3.7: 1. Patients with initial diagnosed cerebral stroke were 78%, secondary 22%. The average age of patients was 63. The big number of strokes was observed in men aged 56-57 years; in women aged 75-77 years. TOAST criteria for subtypes of ischemic stroke were distributed to: atherothrombotic (29,3%, cardioembolic (29,1 %, 22,4% lacunar ischemic stroke due to other established reasons (8,8%, crptogenic (10,4%. Hemorrhagic stroke was observed in 16.8% of cases. Parenchymal hemorrhage was observed in 10.7% of cases, nontraumatic subarachnoid hemorrhage (4,5%. Among the risk factors in patients with ischemic stroke identified: arterial hypertension (88,9%, coronary heart disease (43%, heart rhythm disorders (28,4%, diabetes (18,6%. The proportion of endovascular interventions performed for 3 years was 31.2%. Mortality rate was 3.74% (10 people in 2011; 4.65% (14 people in 2012; 2.48% (7 people in 2013. Conclusion. Follow up the hospital stroke registry allowed to estimate the structure andcourse of cerebral stroke, found the risk factors to identify the most important factors of death.

    Full Text Available Background: Disturbances of microcirculation play a significant role in the development and progression of both acute and chronic cerebrovascular diseases (CVD and may be associated with different hemogram abnormalities. One of the reasons of the prothrombogenic state of the endothelium is the increase in the number of blood corpuscles leading to (non-Ph myeloproliferative disorders (MPD including essential thrombocythemia (ET, polycythemia vera (PV, and primary myelofibrosis (PM. Materials and Methods: The study included 167 patients: 102 patients with Ph-MPD and the control group comprising 65 patients with CVD. According to MPD subtype, the patients were divided into three groups: patients with ET (37%, n = 38, male/female 7/31, age 52 ± 7 years, those with PV (40%, n = 41, male/female 20/21, age 50 ± 6 years and those with PM (23%, n = 23, male/female 5/18, age 54 ± 4 years. Results: In 79% (n = 81 of cases in the study group (with Ph-MPD, patients had chronic CVD, with the most frequently identified symptoms being asthenia (92% and headache (72%. Headache in Ph-MPD patients was more frequently (86% associated with PM, while in patients with PV and ET it was equally distributed (70%. Neurological symptoms in 53% of cases were associated with focal changes of the brain on MRI localized in the subcortical area of the frontal and parietal lobes. Twenty-one (21% patients suffered an acute cerebrovascular accident, 8 of them had thrombotic occlusion of one of the internal carotid arteries leading to hemispheric infarcts. Endothelial function (as measured by flow-dependent dilation of the brachial artery was severely impaired in all study groups (median 5% with normal cut-off at 10%, the lowest degree of vasodilator activity being specific for patients with a history of stroke (p = 0.011. Conclusion: Patients suffering from MPD had asymptomatic focal changes in the brain in the absence of concomitant vascular disease (hypertension

  15. Social Cognition Deficits: Current Position and Future Directions for Neuropsychological Interventions in Cerebrovascular Disease

    Progress Njomboro

    2017-01-01

    Full Text Available Neuropsychological assessments of cognitive dysfunction in cerebrovascular illness commonly target basic cognitive functions involving aspects of memory, attention, language, praxis, and number processing. Here, I highlight the clinical importance of often-neglected social cognition functions. These functions recruit a widely distributed neural network, making them vulnerable in most cerebrovascular diseases. Sociocognitive deficits underlie most of the problematic social conduct observed in patients and are associated with more negative clinical outcomes (compared to nonsocial cognitive deficits. In clinical settings, social cognition deficits are normally gleaned from collateral information from caregivers or from indirect inferences made from patients’ performance on standard nonsocial cognitive tests. Information from these sources is however inadequate. I discuss key social cognition functions, focusing initially on deficits in emotion perception and theory of mind, two areas that have gained sizeable attention in neuroscientific research, and then extend the discussion into relatively new, less covered but crucial functions involving empathic behaviour, social awareness, social judgements, and social decision making. These functions are frequently impaired following neurological change. At present, a wide range of psychometrically robust social cognition tests is available, and this review also makes the case for their inclusion in neuropsychological assessments.

  16. [Lipids and cerebrovascular disease - New therapeutic options in lowering LDL-cholesterol].

    Lovadi, Emese; Csécsei, Péter; Lovig, Csenge; Karádi, Zsófia; Szapáry, László

    2016-12-01

    Stroke is the third most common cause of death worldwide following myocardial infaction and malignancies, furthermore, its functional outcome is the worst of all conditions. Cholesterol, especially LDL-cholesterol plays a key role in the formation of atherosclerotic plaques. It has been verified recently that escalating incidence and mortality of cerebrovascular diseases are proportional to increased levels of LDL-cholesterol. Statin therapy undeniably reduces the risk of stroke, however other methods for decreasing lipid levels have not been proved significantly effective. Preventive effect of high-dose statin treatment is without doubt, although administration of such high dosage might require special precautions for patients with prior intracerebral hemorrhage and it also risks development of incident diabetes. The recently published IMPROVE-IT study is the first to prove that the addition of ezetimibe as a non-statin type drug, to statin treatment contributes to further reduction of LDL-cholesterol. The combination treatment results in additional decrease in the incidence and mortality of cerebrovascular events, without any expansion in the number or adverse effects. These results confirm the importance of any further reduction of LDL-cholesterol levels. Achieving target values with statin-ezetimibe combination allows administration of low to moderate dose of statin, which decreases risks of adverse effects related to high-dose statin therapy. Orv. Hetil., 2016, 157(52), 2059-2065.

    To study the mechanisms underlying stroke-like episodes (SLEs) in MELAS syndrome. We performed a case control study in 3 siblings with MELAS syndrome (m.3243A>G tRNA(Leu(UUR))) with variable % mutant mtDNA in blood (35 to 59%) to evaluate regional cerebral blood flow (CBF) and arterial cerebrovascular reactivity (CVR) compared to age- and sex-matched healthy study controls and a healthy control population. Subjects were studied at 3T MRI using arterial spin labeling (ASL) to measure CBF; CVR was measured as a change in % Blood Oxygen Level Dependent signal (as a surrogate of CBF) to repeated 10 mmHg step increase in arterial partial pressure of CO2 (PaCO2). MELAS siblings had decreased CVR (p ≤ 0.002) and increased CBF (p MELAS disease severity and mutation load were inversely correlated with Interictal CVR and directly correlated with frontal CBF. These metrics offer further insight into the cerebrovascular hemodynamics in MELAS syndrome and may serve as noninvasive prognostic markers to stratify risk for SLEs. Class III.

  18. Cerebrovascular-Reactivity Mapping Using MRI: Considerations for Alzheimer’s Disease

    J. J. Chen

    2018-06-01

    Full Text Available Alzheimer’s disease (AD is associated with well-established macrostructural and cellular markers, including localized brain atrophy and deposition of amyloid. However, there is growing recognition of the link between cerebrovascular dysfunction and AD, supported by continuous experimental evidence in the animal and human literature. As a result, neuroimaging studies of AD are increasingly aiming to incorporate vascular measures, exemplified by measures of cerebrovascular reactivity (CVR. CVR is a measure that is rooted in clinical practice, and as non-invasive CVR-mapping techniques become more widely available, routine CVR mapping may open up new avenues of investigation into the development of AD. This review focuses on the use of MRI to map CVR, paying specific attention to recent developments in MRI methodology and on the emerging stimulus-free approaches to CVR mapping. It also summarizes the biological basis for the vascular contribution to AD, and provides critical perspective on the choice of CVR-mapping techniques amongst frail populations.

    Full Text Available A carência de dados epidemiológicos e a impressão prévia de elevada incidência de acidente vascular cerebral (AVC no Brasil criou o estímulo para estudo institucional prospectivo em Joinville. No período de 1-março-1995 a 1-março-1996, avaliamos o primeiro episódio e episódios recorrentes em AVC, incidência, mortalidade, taxa de fatalidade-caso em 30 dias (letalidade, freqüência de fatores de risco, tempo para admissão hospitalar e distribuição dos infartos cerebrais por subtipos patológicos. Registramos 429 pacientes no período, 320 destes com primeiro episódio. Tomografia de crânio foi realizada em 98% dos casos. A taxa de incidência anual ajustada por idade em primeiro episódio de AVC foi de 156/100000. A distribuição por diagnóstico foi: 73,4% para infarto cerebral, 18.4% para hemorragia cerebral e 7,5% para hemorragia subaracnóide. A taxa de mortalidade anual padronizada foi 25/100000. A letalidade foi 26%. Hipertensão, AVC prévio e diabetes foram os fatores de risco mais freqüentes. Somente 25% dos pacientes chegaram ao hospital nas primeiras três horas iniciais. Concluímos que a taxa de incidência em primeiro episódio de AVC em pacientes institucionalizados em Joinville, Brasil, é elevada. A taxa de mortalidade e letalidade são similares as de outras populações.The paucity of epidemiologic data, and the previous impression of high incidence of cerebrovascular disease in Brazil, made us elaborate a prospective institutional study in Joinville, Brazil, with the objective of identifying first and recurrent episodes in stroke. This study occurred from March 1995 to March 1996. We evaluated during the first episode of stroke: incidence, mortality and fatality-case rate (in 30 days letality, frequency of risk factor, time in hospital and distribution of cerebral infarcts by pathological subtypes. In this period, 429 patients with stroke were registered, 320 with the first episode. 98% of all the patients

  20. Screening for cerebrovascular disease in microcephalic osteodysplastic primordial dwarfism type II (MOPD II): an evidence-based proposal.

    Perry, Luke D; Robertson, Fergus; Ganesan, Vijeya

    2013-04-01

    Microcephalic osteodysplastic primordial dwarfism type II (OMIM 210720) is a rare autosomal recessive condition frequently associated with early-onset cerebrovascular disease. Presymptomatic detection and intervention could prevent the adverse consequences associated with this. We reviewed published cases of microcephalic osteodysplastic primordial dwarfism type II to ascertain prevalence and characteristics of cerebrovascular disease and use these data to propose an evidence-based approach to cerebrovascular screening. Of 147 cases identified, 47 had cerebrovascular disease (32%), including occlusive arteriopathy (including moyamoya) and cerebral aneurysmal disease. Occlusive disease occurred in younger individuals, and progression can be both rapid and clinically silent. A reasonable screening approach would be magnetic resonance imaging and angiography of the cervical and intracranial circulation at diagnosis, repeated at yearly intervals until 10 years, and every 2 years thereafter, unless clinical concerns occur earlier. At present it would appear that this needs to be life-long. Families and professionals should be alerted to the potential significance of neurologic symptoms and measures should be taken to maintain good vascular health in affected individuals.

    2014-01-01

    Preclinical and post-mortem studies suggest that Alzheimer disease (AD) causes cerebrovascular dysfunction, and therefore may enhance susceptibility to cerebrovascular disease (CVD). The objective of this study was to investigate this association in a memory clinic population. The AD biomarkers CSF amyloid β42, amyloid β40 and APOE-ε4 status have all been linked to increased CVD risk in AD, and therefore the first aim of this study was to analyze the association between these biomarkers and CVD. In 92 memory clinic patients the cross-sectional association between AD biomarkersand the severity of CVD was investigated with linear regression analysis. Additionally, we studied whether AD biomarkers modified the relation between vascular risk factors and CVD. CVD was assessed on MRI through a visual rating scale.Analyses were adjusted for age. The second aim of this study was to investigate the association between clinical AD and CVD, where 'clinical AD' was defined as follows: impairment in episodic memory, hippocampal atrophy and an aberrant concentration of cerebrospinal fluid (CSF) biomarkers. 47 of the 92 patients had AD. No association between CSF amyloid β42, amyloid β40 or APOE-ε4 status and CVD severity was found, nor did these AD biomarkers modify the relation between vascular risk factors and CVD. Clinical AD was not associated with CVD severity (p=0.83). Patients with more vascular risk factors had more CVD, but this relationship was not convincingly modified by AD (p=0.06). In this memory clinic population, CVD in patients with AD was related to vascular risk factors and age, comparable to patients without AD. Therefore, in our study, the preclinical and post-mortem evidence that AD would predispose to CVD could not be translated clinically. Further work, including replication of this work in a different and larger sample, is warranted.

    The aim of this study is to explore whether there is a relationship between chronic pancreatitis and cerebrovascular disease in Taiwan. Using the claims data of the Taiwan National Health Insurance Program, we identified 16,672 subjects aged 20 to 84 years with a new diagnosis of chronic pancreatitis from 2000 to 2010 as the chronic pancreatitis group. We randomly selected 65,877 subjects aged 20 to 84 years without chronic pancreatitis as the nonchronic pancreatitis group. Both groups were matched by sex, age, comorbidities, and the index year of diagnosing chronic pancreatitis. The incidence of cerebrovascular disease at the end of 2011 was measured. The multivariable Cox proportional hazards regression model was used to measure the hazard ratio (HR) and 95% confidence interval (CI) for cerebrovascular disease risk associated with chronic pancreatitis and other comorbidities. The overall incidence of cerebrovascular disease was 1.24-fold greater in the chronic pancreatitis group than that in the nonchronic pancreatitis group (14.2 vs. 11.5 per 1000 person-years, 95% CI = 1.19-1.30). After controlling for confounding factors, the adjusted HR of cerebrovascular disease was 1.27 (95% CI = 1.19-1.36) for the chronic pancreatitis group as compared with the nonchronic pancreatitis group. Woman (adjusted HR = 1.41, 95% CI = 1.31-1.51), age (every 1 year, HR = 1.04, 95% CI = 1.04-1.05), atrial fibrillation (adjusted HR = 1.23, 95% CI = 1.02-1.48), chronic kidney disease (adjusted HR = 1.48, 95% CI = 1.31-1.67), chronic obstructive pulmonary disease (adjusted HR = 1.27, 95% CI = 1.16-1.40), diabetes mellitus (adjusted HR = 1.82, 95% CI = 1.72-1.92), hypertension (adjusted HR = 1.66, 95% CI = 1.56-1.76), and peripheral atherosclerosis (adjusted HR = 1.26, 95% CI = 1.06-1.51) were other factors significantly associated with cerebrovascular disease. Chronic pancreatitis is associated with increased

  3. Evaluation of arterial diseases by intravenous digital angiography (IVSDA) and risk factors in patients with cerebrovascular disease

    Fukui, Toshiya

    1989-01-01

    Intravenous digital angiography (IVSDA) has been performed in 1,031 consecutive patients during the previous 4 years. Complications of IVSDA, such as coughing, dermal reaction, nausea and vomiting, occurred in 77 patients (7.5%). Among them, 234 patients with a definite diagnosis of cerebrovascular disease were entered onto this study. On the basis of findings of IVSDA, the patients were largely classified into six groups: internal carotid artery (ICA) occlusion, ICA stenosis, middle cerebral artery (MCA) occlusion, MCA stenosis, marked arterial elongation, and normal findings. A group of the patients with ICA occlusion was characterized by having sudden onset with less complicated hypertension. In this group, etiological factors seemed to be embolism, intra-atheromatic hemorrhage, and dissecting aneurysm, as well as atherosclerosis. Major risk factors were hypertension, smoking, diabetes mellitus, and ischemic heart disease for lesions of the main trunk; and severe hypertension, high hematocrit levels and elevated platelet aggregability for lesions of perforating and small cortical arteries and arterioles. In the case of arterial elongation, platelet aggregability elicited by ADP was not suppressed by antiplatelet agents. These patients need to receive intensive treatment to prevent relapse of the disease. (Namekawa, K)

    Collazo de la Maza, A.; Borron Molinos, M.; Barroso, E.

    1997-01-01

    Thirty eight patients with Cerebrovascular disease, that had suffered a Thrombotic brain infraction, demonstrated by Computed electroencephalogram or Brain Mapping (BM) and Computerized Tomography (CT) were investigated with '99' '9' 'm' Tc HM-PAO brain SPECT. Their ages ranged from 37 to 73 years old, 18 males and 20 female. Some of them were followed up with these diagnostic methods. The acquisition and processing of the SPECT studies were donw with a SOPHY DS7 Gamma Camera. The results showed that the global diagnostic sensibility of the SPECT was 79%. The sensibility of SPECT in the Acute stage was 75 %, CT 57% and BM 92%. In Steady stage we found a high positivity of SPECT with 83 %, Ct 66% and BM 66%. In the Recuperation Stage SPECT was 77%, CT 66% and 45%. Some phenomenon like the Luxury Perfusion and Diaschisis were studied and it is possible to found some prognostic relation

  5. Lack of nocturnal blood pressure fall in elderly bedridden hypertensive patients with cerebrovascular disease.

    Sasaki, Masato; Ando, Hitoshi; Fujimura, Akio

    2012-02-01

    To prevent recurrence of cerebrovascular disease (CVD), adequate control of blood pressure (BP) is extremely important for the treatment of hypertensive CVD patients. As absence of the nocturnal fall of BP by the expected 10-20% from daytime levels is reported to exaggerate target organ injury, 24-h ambulatory blood pressure monitoring (ABPM) was conducted, especially to obtain data during nighttime sleep. Forty-eight elderly bedridden chronic phase CVD hypertensive patients (assessed 1-3 mo after CVD accident) participated. As a group, nocturnal BP was higher than diurnal BP, whereas nocturnal pulse rate was lower than diurnal pulse rate. The nocturnal BP fall was blunted in most (∼90%) of the patients. These results suggest that to perform a rational drug treatment, it is essential to do 24-h ABPM before initiation of antihypertensive therapy in elderly bedridden hypertensive CVD patients.

  6. Impaired cerebrovascular function in coronary artery disease patients and recovery following cardiac rehabilitation.

    Udunna C Anazodo

    2016-01-01

    Full Text Available Coronary artery disease (CAD poses a risk to the cerebrovascular function of older adults and has been linked to impaired cognitive abilities. Using magnetic resonance perfusion imaging, we investigated changes in resting cerebral blood flow (CBF and cerebrovascular reactivity (CVR to hypercapnia in 34 coronary artery disease (CAD patients and 21 age-matched controls. Gray matter volume images were acquired and used as a confounding variable to separate changes in structure from function. Compared to healthy controls, CAD patients demonstrated reduced CBF in the superior frontal, anterior cingulate, insular, pre- and post-central gyri, middle temporal and superior temporal regions. Subsequent analysis of these regions demonstrated decreased CVR in the anterior cingulate, insula, postcentral and superior frontal regions. Except in the superior frontal and precentral regions, regional reductions in CBF and CVR were identified in brain areas where no detectable reductions in gray matter volume were observed, demonstrating that these vascular changes were independent of brain atrophy. Because aerobic fitness training can improve brain function, potential changes in regional CBF were investigated in the CAD patients after completion of a 6-month exercise-based cardiac rehabilitation program. Increased CBF was observed in the bilateral anterior cingulate, as well as recovery of CBF in the dorsal aspect of the right anterior cingulate, where the magnitude of increased CBF was roughly equal to the reduction in CBF at baseline compared to controls. These exercise-related improvements in CBF in the anterior cingulate is intriguing given the role of this area in cognitive processing and regulation of cardiovascular autonomic control.

    2018-02-01

    Small studies have suggested that Marfan syndrome is associated with a number of cerebrovascular complications. We sought to determine whether a clinical diagnosis of Marfan syndrome is associated with a higher prevalence of cerebrovascular diseases than the general population by performing a case-control study of hospitalized patients in the Nationwide Inpatient Sample (NIS). Using the 2000-2012 NIS, we performed a case-control study matching cases of Marfan syndrome to controls without such a diagnosis. The prevalence of various cerebrovascular diseases between the 2 groups were compared, and multivariate logistic regression was used to adjust for suspected comorbidities. Between 2000 and 2012, there were a total of 13,883 discharges carrying a diagnosis of Marfan syndrome. On univariate analysis, patients with Marfan syndrome were more likely to have a primary or secondary diagnosis of hemorrhagic stroke (0.5% versus 0.3%, odds ratio [OR] = 1.56, 95% confidence interval [CI] = 1.06-2.29, P = 0.02) as well as intracranial hemorrhage (subarachnoid hemorrhage [SAH] and hemorrhagic stroke) (0.3% versus 0.2%, OR = 1.72, 95% CI = 1.05-2.82, P = 0.03). Patients hospitalized with Marfan syndrome were significantly more likely to have carotid dissection (0.3% versus 0.0%, OR = 11.69, 95% CI = 3.60-38.08, P Marfan syndrome had significantly higher odds of ischemic stroke (OR = 1.20, 95% CI = 1.02-1.43, P = 0.03), hemorrhagic stroke (OR = 1.75, 95% CI = 1.18-2.63, P = 0.005), carotid artery dissection (OR = 11.94, 95% CI = 4.23-50.03, P Marfan syndrome when compared with controls.

  8. Alzheimer's disease, cerebrovascular dysfunction and the benefits of exercise: from vessels to neurons.

    Lange-Asschenfeldt, Christian; Kojda, Georg

    2008-06-01

    Exercise training promotes extensive cardiovascular changes and adaptive mechanisms in both the peripheral and cerebral vasculature, such as improved organ blood flow, induction of antioxidant pathways, and enhanced angiogenesis and vascular regeneration. Clinical studies have demonstrated a reduction of morbidity and mortality from cardiovascular disease among exercising individuals. However, evidence from recent large clinical trials also suggests a substantial reduction of dementia risk - particularly regarding Alzheimer's disease (AD) - with regular exercise. Enhanced neurogenesis and improved synaptic plasticity have been implicated in this beneficial effect. However, recent research has revealed that vascular and specifically endothelial dysfunction is essentially involved in the disease process and profoundly aggravates underlying neurodegeneration. Moreover, vascular risk factors (VRFs) are probably determinants of incidence and course of AD. In this review, we emphasize the interconnection between AD and VRFs and the impact of cerebrovascular and endothelial dysfunction on AD pathophysiology. Furthermore, we describe the molecular mechanisms of the beneficial effects of exercise on the vasculature such as activation of the vascular nitric oxide (NO)/endothelial NO synthase (eNOS) pathway, upregulation of antioxidant enzymes, and angiogenesis. Finally, recent prospective clinical studies dealing with the effect of exercise on the risk of incident AD are briefly reviewed. We conclude that, next to upholding neuronal plasticity, regular exercise may counteract AD pathophysiology by building a vascular reserve.

  9. Pharmacogenetics of cerebrovascular metabolism modulators in dementia due to Alzheimer’s disease

    Fabricio Ferreira de Oliveira

    2015-03-01

    Full Text Available The aims of this study were to investigate risk factors for cognitive and functional decline among 193 patients with Alzheimer’s disease dementia (AD, and to conduct pharmacogenetic analysis on cerebrovascular metabolism modulators, taking into account APOE haplotypes and the genotypes of ACE, CETP, LDLR and the LXR-β gene. For all patients, later age at AD onset was the most important risk factor for faster cognitive and functional decline, while the late-life coronary heart disease risk was inversely related to cognitive decline only for carriers of APOE4+ haplotypes. Schooling was protective against cognitive decline only for women and carriers of APOE4+ haplotypes, while higher body mass index in late life was protective against cognitive decline only for men. Carriers of the APOE-ε4/ε4 haplotype had earlier AD onset, whereas genotypes of CETP and LDLR that had traditionally been associated with higher risk of AD were associated with later onset of dementia. Angiotensin-converting enzyme inhibitors caused a 50% reduction in Mini-Mental State Examination score changes, and had better disease-modifying properties than did centrally-acting angiotensin-converting enzyme inhibitors alone. Angiotensin receptor blockers had genetically mediated effects that led to faster cognitive and functional decline, while patients with genetic tendencies towards faster cognitive and functional decline had maximum benefits when they used lipophilic statins, and vice versa.

  10. Red Blood Cell Distribution Width: A Novel Predictive Indicator for Cardiovascular and Cerebrovascular Diseases

    2017-01-01

    Full Text Available The red blood cell distribution width (RDW obtained from a standard complete blood count (CBC is a convenient and inexpensive biochemical parameter representing the variability in size of circulating erythrocytes. Over the past few decades, RDW with mean corpuscular volume (MCV has been used to identify quite a few hematological system diseases including iron-deficiency anemia and bone marrow dysfunction. In recent years, many clinical studies have proved that the alterations of RDW levels may be associated with the incidence and prognosis in many cardiovascular and cerebrovascular diseases (CVDs. Therefore, early detection and intervention in time of these vascular diseases is critical for delaying their progression. RDW as a new predictive marker and an independent risk factor plays a significant role in assessing the severity and progression of CVDs. However, the mechanisms of the association between RDW and the prognosis of CVDs remain unclear. In this review, we will provide an overview of the representative literatures concerning hypothetical and potential epidemiological associations between RDW and CVDs and discuss the underlying mechanisms.

  12. Research on the influence factors of the fall efficiency of the hospitalized geriatric patients with cerebrovascular diseases.

    Li, Weili; Cheng, Ruilian

    2016-11-01

    To investigate the fall efficiency and its influence factors of the hospitalized geriatric patients with cerebrovascular diseases. The Modified Fall Efficacy Scale (MFES), Morse Fall Risk Assessment Scales (MFS), Berg Balance Scale (BBS) and Tinetti Gait Analysis (TGA) were adopted and the combined ways of questionnaires and observation were utilized to investigate the 113 hospitalized geriatric patients with cerebrovascular diseases. The fall efficiency of the geriatric patients with cerebrovascular diseases were 7.85±2.57 scores. The two projects "walking up and down stairs" and "taking public transport means" have got the lowest scores; The two projects "stretching out the hand to the box or the drawer for taking something" and "sitting up and down to the chair" have got the highest scores. It was found that there were three factors which had significant influences on the fall efficiency, they were myodynamia of the right upper extremity, Berg balance functions and gait. For the sake of helping the geriatric patients with cerebrovascular diseases to establish the self-confidence of preventing the falls, the medical workers need to take further psychological counseling for the patients and befittingly and specifically to improve the fall efficiency of patients so as to effectively prevent the occurring of the fall on the basis of improving the balance ability and gait of patients.

  13. The role of CT and cerebral angiography in the neurosurgical treatment of cerebrovascular diseases and their sequels

    Bock, W.J.

    1979-01-01

    It is found that for cerebro-vascular diseases which can be surgically treated, neither angiography nor CT alone yields sufficient information. Only a combination of the two methods can help to reach a clear decision; CT is better suited for course control while angiography helps to make a diagnosis and to decide upon the best surgical treatment.

    Björ, Ove; Jonsson, Håkan; Damber, Lena; Burström, Lage; Nilsson, Tohr

    2016-01-01

    A cohort study that examined iron ore mining found negative associations between cumulative working time employed underground and several outcomes, including mortality of cerebrovascular diseases. In this cohort study, and using the same group of miners, we examined whether work in an outdoor environment could explain elevated cerebrovascular disease rates. This study was based on a Swedish iron ore mining cohort consisting of 13,000 workers. Poisson regression models were used to generate smoothed estimates of standardized mortality ratios and adjusted rate ratios, both models by cumulative exposure time in outdoor work. The adjusted rate ratio between employment classified as outdoor work ≥25 years and outdoor work 0-4 years was 1.62 (95 % CI 1.07-2.42). The subgroup underground work ≥15 years deviated most in occurrence of cerebrovascular disease mortality compared with the external reference population: SMR (0.70 (95 % CI 0.56-0.85)). Employment in outdoor environments was associated with elevated rates of cerebrovascular disease mortality. In contrast, work in tempered underground employment was associated with a protecting effect.

  17. Systems pharmacology for traditional Chinese medicine with application to cardio-cerebrovascular diseases

    Yingxue Fu

    2014-10-01

    Full Text Available Identified as a treasure of natural herbal products, traditional Chinese medicine (TCM has attracted extensive attention for their moderate treatment effect and lower side effect. Cardio-cerebrovascular diseases (CCVD are a leading cause of death. TCM is used in China to prevent and treat CCVD. However, the complexity of TCM poses challenges in understanding the mechanisms of herbs at a systems-level, thus hampering the modernization and globalization of TCM. A novel model, termed traditional Chinese medicine systems pharmacology (TCMSP analysis platform, which relies on the theory of systems pharmacology and integrates absorption, distribution, metabolism, excretion and toxicity (ADME/T evaluation, target prediction and network/pathway analysis, was proposed to address these problems. Here, we review the development of systems pharmacology, the TCMSP approach and its applications in the investigations of CCVD and compare it with other methods. TCMSP assists in uncovering the mechanisms of action of herbal formulas used in treating CCVD. It can also be applied in ascertaining the different syndrome patterns of coronary artery disease, decoding the multi-scale mechanisms of herbs, and in understanding the mechanisms of herbal synergism.

    1988-04-01

    From December 1985 to May 1986, cerebral blood flow (CBF) was studied in 11 patients with occlusive cerebrovascular diseases confined by angiography. 133Xe (5mci) intravenous injection method designed by Kuikka and coworkers was applied for the measurement of regional-CBF and mean-CBF, and the calculation was based on the initial slope index. They were composed of 4 patients of the middle cerebral artery occlusion, 2 of the posterior cerebral artery occlusion, 1 of the internal carotid artery occlusion, 2 of the middle cerebral artery stenosis, 1 of the internal carotid artery stenosis, and 1 of the anterior cerebral artery stenosis. The period from the vascular attack to the initial CBF study was 2-29 days(mean 9.2 days). Recovery of mean-CBF was correlated with clinical and neurological improvement, and vice versa. There was no correlation between mean-CBF and neurological severity. CBF study alone is not sufficient to evaluate neuronal conditions in the occlusive disease. Additional other means, such as CT-scan, angiography and etc. should be requested for it. Intravenous 133Xe injection technique has an advantage over intracarotid injection method; less dangerous, especially in ages and capable of simultaneous measurement of bilateral hemisphere. Considering /sup c/ross talk/sup /regional-CBF of a low density area on X-ray CT-scan was equal to the one obtained by intracarotid injection method.

    Cerebrovascular Disease (CVD) is also called stroke in Traditional Chinese Medicine (TCM). CVD is a kind of frequent diseases with high incidence, high death rate, high deformity rate and high relapse rate. The pathogenesis of CVD has relation to many factors. In modern medicine, we can make use of various instruments to check many biochemical parameters. However, at present, the early detection of CVD can mostly be done artificially by specialists. In TCM the salted expert can detect the state of a CVD patient by felling his (or her) pulse. It is significant to apply the modern information and engineering techniques to the early discovery of CVD. It is also a challenge to do this in fact. In this paper, the authors presented a detection method of CVD basing on analysis and pattern recognition of Manifestation of the Pulse of TCM using wavelet technology and Neural Networks. Pulse signals from normal health persons and CVD patients were studied comparatively. This research method is flexible to deal with other physiological signals.

    1994-01-01

    Cerebral blood volume before and after acetazolamide was measured by SPECT to evaluate cerebral vasodilatory capacity in eight patients with cerebrovascular disease and five control subjects. Two SPECT measurements were performed serially, and acetazolamide was administered between them. The ratio of increase in hemispheric blood volume was calculated, and it was compared with the results of cerebral blood flow and cerebral blood volume measurements. A cerebral vasodilatory capacity map, the image after acetazolamide minus the baseline image, was also produced. Acetazolamide increased hemispheric blood volume in all subjects. The ratio of increase was lower in the involved hemispheres of the patients with unilateral carotid disease than in the uninvolved hemispheres of the patients and control subjects. The ratio of concordance with blood flow and blood volume measurements was approximated at 80%. Cerebral vasodilatory capacity mapping revealed three defects compatible with the clinical data. SPECT measurements of cerebral blood volume after acetazolamide can be performed following baseline SPECT with no additional radiotracer, and may be helpful to assess hemodynamic status. (author)

    White matter lesions (WMLs) and cerebral infarcts are common findings in Alzheimer disease and may contribute to dementia severity. WMLs and lacunar infarcts may provide a potential target for intervention strategies. This study assessed whether multicomponent vascular care in patients with Alzheimer disease with cerebrovascular lesions slows progression of WMLs and prevents occurrence of new infarcts. A randomized controlled clinical trial, including 123 subjects, compared vascular care with standard care in patients with Alzheimer disease with cerebrovascular lesions on MRI. Progression of WMLs, lacunes, medial temporal lobe atrophy, and global cortical atrophy were semiquantitatively scored after 2-year follow-up. Sixty-five subjects (36 vascular care, 29 standard care) had a baseline and a follow-up MRI and in 58 subjects, a follow-up scan could not be obtained due to advanced dementia or death. Subjects in the vascular care group had less progression of WMLs as measured with the WML change score (1.4 versus 2.3, P=0.03). There was no difference in the number of new lacunes or change in global cortical atrophy or medial temporal lobe atrophy between the 2 groups. Vascular care in patients with Alzheimer disease with cerebrovascular lesions slows progression of WMLs. Treatment aimed at vascular risk factors in patients with early Alzheimer disease may be beneficial, possibly in an even earlier stage of the disease.

  2. Risk factors for cerebrovascular disease mortality among the elderly in Beijing: a competing risk analysis.

    Zhe Tang

    Full Text Available OBJECTIVE: To examine the associations of combined lifestyle factors and physical conditions with cerebrovascular diseases (CBVD mortality, after accounting for competing risk events, including death from cardiovascular diseases, cancers and other diseases. METHODS: Data on 2010 subjects aged over 55 years were finally analyzed using competing risk models. All the subjects were interviewed by the Beijing Longitudinal Study of Aging (BLSA, in China, between 1 January 1992 and 30 August 2009. RESULTS: Elderly females were at a lower risk of death from CBVD than elderly males (HR = 0.639, 95% CI = 0.457-0.895. Increasing age (HR = 1.543, 95% CI = 1.013-2.349, poor self-rated health (HR = 1.652, 95% CI = 1.198-2.277, hypertension (HR = 2.201, 95% CI = 1.524-3.178 and overweight (HR = 1.473, 95% CI = 1.013-2.142 or obesity (HR = 1.711, 95% CI = 1.1754-2.490 was associated with higher CBVD mortality risk. Normal cognition function (HR = 0.650, 95% CI = 0.434-0.973 and living in urban (HR = 0.456, 95% CI = 0.286-0.727 was associated with lower CBVD mortality risk. Gray's test also confirmed the cumulative incidence (CIF of CBVD was lower in the 'married' group than those without spouse, and the mortality was lowest in the 'nutrition sufficient' group among the 'frequent consumption of meat group' and the 'medial type group' (P value<0.001. CONCLUSIONS: CBVD mortality was associated with gender, age, blood pressure, residence, BMI, cognitive function, nutrition and the result of self-rated health assessment in the elderly in Beijing, China.

  3. Regional cerebral blood studies by the xenon-133 inhalation method in cases of cerebrovascular diseases

    Shimomura, Takahide

    1982-01-01

    rCBF was measured 428 times in 191 patients and 15 healthy volunteers by the Xenon-133 inhalation technique. The two-compartment analysis and the estimate of initial slope index were performed. There was no difference in blood flow between the two hemispheres in the 15 healthy volunteers, whose mean age was 36.5 +- 13.5 years (F 1 , right: 83.1 +- 11.4; left: 85.1 +- 12.1; 1Sl, right: 51.6 +- 6.3; left: 52.4 +- 6.0). Good correlation with a correlation coefficient of 0.965 was observed between the value obtained by the Xenon-133 inhalation and intracarotid methods in 14 patients with brain diseases. Reproducibilities of the Xenon-133 inhalation technique by serial measurement of rCBF at intervals of 30 - 40 minutes and 3 - 5 days were almost the same, with a variation coefficient of 3.7% and a correlation coefficient of 0.98. Repeated rCBF measurement by the Xenon-133 inhalation was performed during a long follow-up period of up to 1 year after bypass surgery. In 28 adult patients with occlusive cerebrovascular disease, CBF values of most patients stabilized in normal range within 3 months after the operation. In 12 patients with Moyamoya disease, CBF values were distributed over a wide range preoperatively, and increased gradually and tended to stabilize in the relatively subnormal range within 3 months after operation. This clinical experience indicates that the Xenon-133 inhalation method is a useful and safe procedure for the determination of rCBF, especially for repeated studies in cases with bypass surgery during long postoperative follow-up periods and for measurement of rCBF in child cases.

  4. The Different Effects Of Endogenous And Exogenous Sex Hormones On Cerebrovascular Diseases

    2017-02-01

    Full Text Available Background: A sexual dimorphism is seen in ischemic stroke. Women have lower stroke incidence than men until an advanced age, when the epidemiology of ischemic stroke shifts and incidence rises dramatically in women. This could indicate the role of sex hormones in pathogenesis of cerebrovascular diseases. This Review summarizes the sex differences related to stroke, and the effects of endogenous and exogenAous hormones on the cerebrovasculature of the male and female brain. Methods: We conducted a vast review to analyze possible associations between exposure to endogenous and exogenous female and male steroid hormones and the risks of cerebrovascular diseases. This association is discussed in the context of the effects of sex hormone levels on the progression of atherosclerosis, the vascular tone, and various risk factors including patient's lipid profile, arterial blood pressure and diabetes. Their therapeutic potentials is also reviewed. Results: There is a debate on the role of androgens. A large array of data testifies in favor of a variety of neuroprotective androgen effects in men mostly, but in many cases in women as well. Testosterone supplementation in low to normal levels in hypogonadal men has mostly been shown to benefit the subjects receiving it, but administration in supraphysiological doses however, along with anabolic steroid abuse, seems to adversely affect both the lipid profile and insulin sensitivity in men. Its effects in women have yet to be researched in depth. Due to the lower stroke incidence observed in pre-menopausal women and robust preclinical evidence of neuroprotective and anti-inflammatory properties of estrogen, researchers have focused on the potential benefits of hormones to reduce ischemic brain injury. However, hormone therapy to postmenopausal females increases the risk and severity of ischemic stroke. Moreover, while estrogen treatment is neuroprotective in younger females, estrogen paradoxically increases

    1980-10-01

    A study was made of the incidence of cerebrovascular diseases, their chronological trend, and relationship between the disease types and risk factors on 16,491 subjects of Hiroshima and Nagasaki who underwent medical examination at least once between 1958 - 74, and who were free of cerebrovascular disease at the initial examination. During the 16-year period, 1,162 cases of cerebrovascular disease developed in this study population with the diagnosis definite in 621, and the annual incidence was 3.2 per 1,000 population. By type, there were 108 cases of cerebral hemorrhage, 469 cases of cerebral infarction, 33 cases of subarachnoid hemorrhage, and 11 cases of other unclassifiable types, with cerebral infarction occurring more frequently than cerebral hemorrhage at the ratio of 4.5 : 1. The incidence of cerebrovascular diseases increased with age in both types, but the proportion of younger subjects in cerebral hemorrhage was greater than that in cerebral infarction. A secular trend of declining incidence was noted for both cerebral hemorrhage and cerebral infarction. As a risk factor of cerebral hemorrhage, elevation of systolic and diastolic blood pressure was the most closely related to onset, and left ventricular hypertrophy on electrocardiogram (ECG) and proteinuria were also related. However, a tendency was seen for the risk to be somewhat higher the lower the levels of serum cholesterol. In cerebral infarction, aging, like systolic blood pressure, was a most important risk factor. Left ventricular hypertrophy on ECG, proteinuria, and diabetes could also be risk factors. However, the relation to blood pressure, especially diastolic blood pressure, was not so great as in the case of cerebral hemorrhage. (author)

  6. Evaluation of successive Tc-99m brain angiography and vasoactive drugs on occlusive cerebrovascular disease

    Shimamura, Osamu

    1986-01-01

    Cerebral circulation in the patients with unilateral occlusive cerebrovascular disease (CVD) in chronic stage was evaluated by radionuclide angiography (RNA) using Tc-99m pertechnetate. RNA (each Tc-99m dose = 20 mCi) was repeated in short time interval. Employed parameters were as follows; appearance to peak time (APT), brain transit time (BTT), peak count (PC) and up slope (US). These parameters were calculated from time activity curve (TAC) of ''region of interest'' on each hemisphere and the values obtained in affected side were compared with those of normal side and control hemisphere. Reproducibility of these values were satisfactory in PC and US. The results obtained were as follows: In affected hemisphere, PC and US were significantly reduced, while APT and BTT were not significantly affected. The ratio of PC and US between left and right hemispheres increased in the patients with CVD and the latter was particularly significant to detect the abnormality. Effect of vasoactive drugs such as papaverine, acetazolamide, angiotensin II or methoxamine on these parameters was studied in 24 patients with CVD and 16 patients without CVD. Papaverine and acetazolamide increased significantly PC and US in normal hemisphere of patients without CVD and US in normal hemisphere of patients with CVD, while US in these hemispheres were decreased under high blood pressure induced by angiotensin II and methoxamine. These responses, however, were mild or not detected in the affected hemispheres. (J.P.N.)

  7. Relationship between the severity of obstructive sleep apnea syndrome and asymptomatic cerebrovascular disease

    Nishibayashi, Momoka

    2008-01-01

    In this study, examined were prevalence of asymptomatic cerebrovascular disease (ACD) in patients with obstructive sleep apnea syndrome (OSAS) and relationship between its severity and ACD prevalence. Subjects were 192 cases (M 170/F 20, av. age 50.6 y) with chief complaint of snore, sleep apnea (apnea-hypopnea index/AHI 0-118.4/h), midday drowsiness and so on without CD history, who underwent the overnight polysomnographic recording, vascular risk assessment like life habits, blood pressure and impaired GT, and brain MRI. The last item was conducted with Siemence 1.5T machine to get T1-, T2-weighted and FLAIR images to evaluate asymptomatic lacunar infarction (ALI) and periventricular hyperintensity (PVH). Light (AHI<15/h), moderate (15≤AHI<30) and severe (AHI≥30) OSASs were found in 44, 35 and 61 cases, respectively. ALIs were found in 7 light, 17 moderate and 61 severe cases and PVH, in 9, 19 and 61 cases, respectively. Thus it was revealed that patients with moderate to severe OSAS had complication of ACD in a higher rate than those with light OSAS and that prevalence of ACD was higher in OSAS patients with AHI 15/h or more.

    Ekpebegh, C; Longo-Mbenza, B

    2013-06-01

    Aim of the present study was to determine syndrome specific mortality rates and the precipitating factors associated with deaths following admission for hyperglycemic crisis to a high care unit. Retrospective review of medical records for hyperglycemic crisis at Nelson Mandela Academic Hospital, Mthatha, Eastern Cape Province of South Africa from February 1 2010 to January 31 2011. All admissions were initially into the high care unit. The overall mortality rates (per admissions) was 13.9% (N.=15/108) with syndrome specific mortality rates (per admissions) of 11.9% (N.=8/67), 0% (N.=0/8) and 21.2% (N.=7/33) respectively for diabetic ketoacidosis (DKA), hyperglycemic hyperosmolar state (HHS) and hyperglycemia with dehydration (HD). The precipitating factors that were mainly associated with mortality were infections and cerebrovascular disease (CVD). The patients with CVD who died were all unconscious. There were no deaths where non-compliance with hypoglycaemic agents (14.8%, N.=16/108) was the precipitating factor. The overall mortality rates (per admissions) following high care unit admissions for hyperglycemic crisis was 13.9% with infections and CVD as the precipitating factors most associated with deaths.

  9. Cerebral blood flow mapping using stable xenon-enhanced CT in sickle cell cerebrovascular disease

    Numaguchi, Y.; Robinson, A.E.; Carey, J.E.

    1990-01-01

    The cerebral blood flow (CBF) of 25 patients with sickle cell cerebrovascular disease (SCCVD) was examined using a xenon-CT flow mapping method. Brain CT and MR findings were correlated with those of the xenon-CT flow studies. CBF defects on xenon-CT correlated reasonably well with the areas of cortical infarctions on the MR images, but in 27% of the cases, flow defects were slightly larger than the areas of infarctions on the MR images. In deep watershed or basal ganglia infarctions, abnormal CBF was noted about the cerebral cortex near infarctions in 72% of the patients, regardless of infarction sizes on the MR images. However, decreased CBF was recognized in 4 of the 9 children whose MR images were virtually normal. Thus, the extent of flow depletion cannot be predicted accurately by MR imaging alone. Xenon-CT flow mapping proved a safe and reliable procedure for evaluation of the CBF of patients with SCCVD. Although this study is preliminary, it may have a potential in selecting patients for hypertransfusion therapy, as a noninvasive test and for following children with SCCVD during their therapy. Careful correlation of results of CBF with those of MR imaging or of CT is important for objective interpretations of flow mapping images. (orig.)

  10. The nuclear receptor PPARγ as a therapeutic target for cerebrovascular and brain dysfunction in Alzheimer's disease

    Nektaria Nicolakakis

    2010-05-01

    Full Text Available Peroxisome proliferator-activated receptors (PPARs are ligand-activated nuclear transcription factors that regulate peripheral lipid and glucose metabolism. Three subtypes make up the PPAR family (α, γ, β/δ, and synthetic ligands for PPARα (fibrates and PPARγ (Thiazolidinediones, TZDs are currently prescribed for the respective management of dyslipidemia and type 2 diabetes. In contrast to the well characterized action of PPARs in the periphery, little was known about the presence or function of these receptors in the brain and cerebral vasculature, until fairly recently. Indeed, research in the last decade has uncovered these receptors in most brain cell types, and has shown that their activation, particularly that of PPARγ, is implicated in normal brain and cerebrovascular physiology, and confers protection under pathological conditions. Notably, accumulating evidence has highlighted the therapeutic potential of PPARγ ligands in the treatment of brain disorders such as Alzheimer’s disease (AD, leading to the testing of the TZDs pioglitazone and rosiglitazone in AD clinical trials. This review will focus on the benefits of PPARγ agonists for vascular, neuronal and glial networks, and assess the value of these compounds as future AD therapeutics in light of evidence from transgenic mouse models and recent clinical trials.

  11. Clinical aspects and prognosis of intraventricular hemorrhage with cerebrovascular disease. CT findings and etiological analysis

    Ikeda, Yukio; Nakazawa, Shozo; Higuchi, Hiroshi; Ueda, Kenji; Kouzo, [Nippon Medical School, Tokyo

    1982-10-01

    Intraventricular hemorrhage with cerebrovascular disease was identified in 81 cases and death occurred within seven days in 34 cases. Hypertension was the most common etiological factor, accounting for 40 of the 81 cases. Cerebral aneurysm was the second most common cause accounting for 27 cases, arteriovenous malformation accounted for 9 of the cases, and 5 were of other causes. Signs of primary or secondary brain stem dysfunction were mainly seen in cases with hypertension and aneurysm, while cases with arteriovenous malformation had benign courses. The mortality depended on the severity of intraventricular hemorrhage; i.e., the distribution, site, and the number of cast formation. The presence of intraventricular clot in the third and/or fourth ventricles was correlated with a high mortality rate, especially in cases accompanied by cast formation and third and fourth ventricular dilatation, which affects hypothalamus and brain stem function. Analysis of CT findings for the mechanism of intraventricular hemorrhage revealed three types: extension type, in which massive intracerebral hematomas extended and ruptured into ventricles; the direct type, which bled directly into ventricles without forming definite intracerebral hematomas; and the reflux type, which was characterized by reflux of the subarachnoid blood.

    1990-09-01

    Stable xenon (Xe{sup s}) is used as a contrast agent because it freely diffuses to cerebral tissues through the blood-brain barrier. In this study, 2 axial levels for Xe{sup s} enhancement analysis were selected from a baseline series of computed tomographic (CT) scans and 6 serial CT scans were obtained every 20 seconds for each scan level during the 240 seconds inhalation period of 30% Xe{sup s} in 10 volunteer controls and in 52 patients with ischemic cerebrovascular diseases (ICVD). The serial CT scans were added and averaged in each pixel. This was used to make a new CT picture (addition CT scans). The CT scans before the Xe{sup s} inhalation, the scan at the end of the Xe{sup s} inhalation, and the addition CT scan were compared to see whether gray matter and ischemic areas could be differentiated from white matter. The addition CT scans could differentiate the three structures very well in both the acute and chronic stages of ICVD. This technique is thought to be a very simple and useful method to detect the small infarcted areas and low perfusion areas that cannot be visualized on precontrast CT scans. (author).

    2017-03-15

    In recent decades, mortality rates for cerebrovascular diseases (CVD) have decreased significantly in many countries. This study analyses recent tendencies in CVD mortality rates in Andalusia (1980-2014) to identify any changes in previously observed sex and age trends. CVD mortality and population data were obtained from Spain's National Statistics Institute database. We calculated age-specific and age-standardised mortality rates using the direct method (European standard population). Joinpoint regression analysis was used to estimate the annual percentage change in rates and identify significant changes in mortality trends. We also estimated rate ratios between Andalusia and Spain. Standardised rates for both males and females showed 3 periods in joinpoint regression analysis: an initial period of significant decline (1980-1997), a period of rate stabilisation (1997-2003), and another period of significant decline (2003-2014). Between 1997 and 2003, age-standardised rates stabilised in Andalusia but continued to decrease in Spain as a whole. This increased in the gap between CVD mortality rates in Andalusia and Spain for both sexes and most age groups. Copyright © 2017 The Author(s). Publicado por Elsevier España, S.L.U.

    Abnormalities of the retinal circulation may be associated with cerebrovascular disease. We investigated associations between retinal microvascular abnormalities and (1) strokes and subclinical cerebral infarcts and (2) cerebral white matter lesions in a UK-based triethnic population-based cohort. A total of 1185 participants (age, 68.8±6.1 years; 77% men) underwent retinal imaging and cerebral magnetic resonance imaging. Cerebral infarcts and white matter hyperintensities were identified on magnetic resonance imaging, retinopathy was graded, and retinal vessels were measured. Higher retinopathy grade (odds ratio [OR], 1.40 [95% confidence interval (95% CI), 1.16-1.70]), narrower arteriolar diameter (OR, 0.98 [95% CI, 0.97-0.99]), fewer symmetrical arteriolar bifurcations (OR, 0.84 [95% CI, 0.75-0.95]), higher arteriolar optimality deviation (OR, 1.16 [95% CI, 1.00-1.34]), and more tortuous venules (OR, 1.20 [95% CI, 1.09-1.32]) were associated with strokes/infarcts and white matter hyperintensities. Associations with quantitative retinal microvascular measures were independent of retinopathy. Abnormalities of the retinal microvasculature are independently associated with stroke, cerebral infarcts, and white matter lesions. © 2016 American Heart Association, Inc.

    The contrast enhancement of cerebro-vascular diseases on CT is thought to be due to the increase of the cerebral blood volume (CBV) and/or the disruption of the blood brain barrier (BBB). However, it is difficult to differentiate these two conditions only by contrast enhanced CT. We employed dynamic CT (DCT) to analyse these lesions with respect to the patterns of time-density curve and peak height (PH) of the curve upon the theoretical basis that flattening of the latter part of the time-density curve reflected the degree of BBB disruption and PH reflected the CBV. In all cases of hypertensive intracerebral hemorrhage (11 cases), the contrast enhanced lesion around the hematoma showed marked BBB disruption according to the results of DCT. In 11 cases of cerebral infarction, patterns of BBB disruption and CBV varied at the contrast enhanced lesions according to the result of DCT. However, all contrast enhanced lesions with increased PH were associated with hemorrhagic infarction. Thus, the precise analysis of DCT provides appropriate therapeutic schedules by predicting the occurrence of hemorrhagic infarction. (author)

    NMR images and T 1 values, which were obtained by a Fonar QED 80-α system, were investigated in patients with cerebrovascular disease. In patients with intracerebral hemorrhage, hematoma was seen as high density area on steady state free precession images, and the extension of hematoma and its surrounding edema was also visualized frequently at the onset. T 1 values are generally high in the area of edema. T 1 values and their changes are thus considered useful in selecting the method of treatment. In patients with cerebral infarction, lesions were seen as high density areas. This was noted in serious cases, i.e., the areas corresponding to low density areas on CT were visualized as high density areas on NMR imaging. T 1 values were high especially in the center part of the infarct area, and tended to be prolonged with time. Prolongation of T 1 during the chronic stage seems to provide information concerning degeneration of tissues. Local T 1 values, as well as image findings, have a great significance for the clinical application of NMR technique. Sequential observations of T 1 values seem to make a large contribution to the pathological elucidation. (Namekawa, K.)

    The Women's Health Initiative Memory Study (WHIMS) hormone therapy (HT) trials reported that conjugated equine estrogen (CEE) with or without medroxyprogesterone acetate (MPA) increases risk for all-cause dementia and global cognitive decline. WHIMS MRI measured subclinical cerebrovascular disease as a possible mechanism to explain cognitive decline reported in WHIMS. We contacted 2,345 women at 14 WHIMS sites; scans were completed on 1,424 (61%) and 1,403 were accepted for analysis. The primary outcome measure was total ischemic lesion volume on brain MRI. Mean duration of on-trial HT or placebo was 4 (CEE+MPA) or 5.6 years (CEE-Alone) and scans were conducted an average of 3 (CEE+MPA) or 1.4 years (CEE-Alone) post-trial termination. Cross-sectional analysis of MRI lesions was conducted; general linear models were fitted to assess treatment group differences using analysis of covariance. A (two-tailed) critical value of alpha = 0.05 was used. In women evenly matched within trials at baseline, increased lesion volumes were significantly related to age, smoking, history of cardiovascular disease, hypertension, lower post-trial global cognition scores, and increased incident cases of on- or post-trial mild cognitive impairment or probable dementia. Mean ischemic lesion volumes were slightly larger for the CEE+MPA group vs placebo, except for the basal ganglia, but the differences were not significant. Women assigned to CEE-Alone had similar mean ischemic lesion volumes compared to placebo. Conjugated equine estrogen-based hormone therapy was not associated with a significant increase in ischemic brain lesion volume relative to placebo. This finding was consistent within each trial and in pooled analyses across trials.

    The minimum basic dataset is the largest available hospital care administrative database that is used in clinical studies and hospital management in association with diagnosis-related groups (DRGs). In 2011, the quality of the national MBDS in hospital discharges was audited, in order to assess its reliability. This paper presents a sub-analysis of the results from that analysis which are referred to cerebrovascular disease (CVD). Using all discharge reports from the Spanish MBDS in 2009, a representative sample was obtained by stratified sampling and 11 209 records were evaluated. Outcome indicators were obtained to measure any differences observed between the national MBDS being evaluated and the hospital's original MBDS. Analysis of codes for CVD as a primary diagnosis was performed for ICD-9-CM diagnostic categories 430 through 438. We evaluated error rates in the selection and classification of main diagnoses, as well as in DRG assignment. There were 397 discharges of cases of CVD which included 21 different DRGs. Diagnostic coding showed a concordance rate of 81.87%; the selection error rate was 2.26% and the classification error rate was 15.87%. The error rate in the DRG was 16.12% and associated with the greatest impact on the mortality risk level. While the errors we observed must be taken into account, data suggest that the quality of the MBDS for CVD is sufficient to ensure delivery of valid information. The hospital discharge registry serves as a valuable tool for use in studies of this disease. Copyright © 2014 Sociedad Española de Neurología. Publicado por Elsevier España, S.L.U.

    1979-01-01

    The reliability of computed tomography (CT) in the diagnosis of cerebrovascular diseases was studied by comparing CT images and neuropathological findings in 38 autopsied cases. Our special concern was directed toward several factors which caused false positive and false negative results in CT: the size and location of lesions, and the interval between the onset of the disease and the time of CT studies. Infarctions smaller than 5 mm should be interpreted as such with great care, because only 32.1% of them could be detected in CT, and 81.0% of small low density areas supposed to be small infarctions in CT films proved to be false positive in postmortem examination. 41.9% of middle-sized infarctions were detected in CT and 40.9% of middle-sized low density areas were false positive. Most of false positive low density areas appeared on the surface of the cerebrum where deep sulci join, or in the white matter anterior to the anterior horn or posterior to the posterior horn of the lateral ventricles. The possibility of false positive findings became far less, when the number of slices showing low density areas increased. All of the large infarctions were detected in CT. However, immediately after stroke they did not stand out as low density areas. In such cases, the decrease of cerebral sulci due to brain edema and signs of compression in the ventricular system could be the clues to make the diagnosis of large infarctions. The diagnosis of hemorrhagic infarctions was often difficult. Cerebral bleeding could be diagnosed easily by CT in its early period. However, old hematomas which rapidly resolved and became shrunken, could hardly be identified in CT. (author)

  20. Imaging of Cerebrovascular Pathology in Animal Models of Alzheimer`s Disease

    2014-03-01

    Full Text Available In Alzheimer’s disease (AD, vascular pathology may interact with neurodegeneration and thus aggravate cognitive decline. As the relationship between these two processes is poorly understood, research has been increasingly focused on understanding the link between cerebrovascular alterations and AD. This has at last been spurred by the engineering of transgenic animals, which display pathological features of AD and develop cerebral amyloid angiopathy to various degrees. Transgenic models are versatile for investigating the role of amyloid deposition and vascular dysfunction, and for evaluating novel therapeutic concepts. In addition, research has benefited from the development of novel imaging techniques, which are capable of characterizing vascular pathology in vivo. They provide vascular structural read-outs and have the ability to assess the functional consequences of vascular dysfunction as well as to visualize and monitor the molecular processes underlying these pathological alterations. This article focusses on recent in vivo small animal imaging studies addressing vascular aspects related to AD. With the technical advances of imaging modalities such as magnetic resonance, nuclear and microscopic imaging, molecular, functional and structural information related to vascular pathology can now be visualized in vivo in small rodents. Imaging vascular and parenchymal amyloid-β (Aβ deposition as well as Aβ transport pathways have been shown to be useful to characterize their dynamics and to elucidate their role in the development of cerebral amyloid angiopathy and AD. Structural and functional imaging read-outs have been employed to describe the deleterious affects of Aβ on vessel morphology, hemodynamics and vascular integrity. More recent imaging studies have also addressed how inflammatory processes partake in the pathogenesis of the disease. Moreover, imaging can be pivotal in the search for novel therapies targeting the vasculature.

  1. The effects of 'Oren-gedoku-to' and quantitative evaluation of cerebral blood flow for cerebrovascular diseases

    Ushikubo, Yukio; Sakurai, Takatoshi; Yokouchi, Tetuya

    1998-01-01

    Fifty-seven patients with sequela of cerebrovascular diseases were treated with 'Oren-gedoku-to' for 8 weeks to examine the possibilities of improvements in subjective symptom, motive deterioration, mental disorder, unusual behaviors and intellectual malfunction. These symptoms showed improvement of 41.6%, 54.2%, 75.0%, 63.0%, 21.3%, respectively. For 21 patients, amount of regional cerebral blood flow were measured with SPECT. Results showed an increase of 1.7ml/100g/min. at average. However, there was no statistical difference observed among 'improved' cases, 'slightly improved' cases and 'no change or deteriorated' cases. 'Oren-gedoku-to' worked effectively for cerebrovascular diseases with the exception of intellectual malfunction. Results of the SPECT suggest though, it is uncertain whether these improvements were brought about by the increase of cerebral blood flow. (author)

    Aspirin (ASA) is the mainstay of treatment in cerebrovascular and systemic vascular disease. ASA hypersensitivity can pose a challenge to achieving optimum medical management prior to and after neurointerventional treatment. Desensitization to ASA is well described in the allergy and cardiovascular literature, but there are no similar discussions specific to neurointervention. The purpose of our study was to describe our experience with ASA hypersensitivity management and review the relevant literature. Two cases of patients with symptomatic cerebrovascular disease requiring neurointervention who were successfully desensitized to their ASA hypersensitivity prior to treatment are described. The subsequent literature is reviewed. Several ASA desensitization protocols exist and have been proven to successfully treat ASA hypersensitivity and allow for ASA therapy to be safely initiated. We describe several previously published protocols. ASA desensitization is a safe and simple way to manage ASA hypersensitivity. We provide comprehensive management guidelines for the neurointerventionalist engaging in ASA desensitization.

    Full Text Available Abstract INTRODUCTION: Cardiovascular diseases (CVD and cerebrovascular diseases (CeVD are a large and growing problem in low- and middle-income populations. Secondary prevention, which can reduce the risk of recurrent CVD includes changes in lifestyle, pharmacological interventions and revascularization procedures. The aim of the first phase of this project was to perform situation analysis and identify gaps in secondary prevention of major cardiovascular diseases. This study estimated the physicians' awareness and the patients' knowledge and behavior towards CVD and CeVD complications. It also assessed the efficacy of methods for decreasing recurrent events. methods: A sample of consecutive patients was selected from the outpatient units of the health care facilities selected for the study. Stratified random sampling of primary and secondary private and public health care facilities in cities and villages was performed to select 449 eligible cases. A total of 257 men and 192 women were selected. The inclusion criteria were as follows: Age above 21 years, established diagnosis of CVD and/or CeVD defined as any of the following alone or in combination with others: previous myocardial infarction, stable/unstable angina, percutaneous transluminal coronary angioplasty (PTCA, coronary artery bypass graft (CABG, stroke, transient ischemic attack (TIA, and/or carotid arterectomy. The patients were included if their first event had occurred more than a month, but no earlier than three years before the study. results: The prevalence of high systolic and diastolic blood pressure was 40.1% and 26.9% respectively in MI patients, and 70.1% and 51.2% respectively in CeVD patients. In most of the patients, fasting blood sugar and total cholesterol were within the normal range. Among MI patients, 93.9%, 68.5% and 48.2% were already taking aspirin, beta-blockers and statins, respectively. Among CeVD patients, 79.9%, 61.1% and 23.2% were taking aspirin, beta

    The protective effect of dexmedetomidine on cognitive dysfunction and decreased attention network function of patients with ischemic cerebrovascular disease after stenting was investigated. Fifty-eight patients with ischemic cerebrovascular disease undergoing stenting in Guizhou Provincial People's Hospital were selected and randomly divided into control group (n=29) and dexmedetomidine group (n=29). The dexmedetomidine group was treated with dexmedetomidine before induced anesthesia, while the control group was given the same dose of normal saline; and the normal volunteers of the same age were selected as the normal group (n=29). At 3 days after operation, the levels of serum S100B and nerve growth factor (NGF) in each group were detected using the enzyme-linked immunosorbent assay, and the level of brain-derived neurotrophic factor (BDNF) was detected via western blotting. Montreal cognitive assessment (MoCA) and attention network test (ANT) were performed. Moreover, the cognitive function and attention network function, and the effects of dexmedetomidine on cognitive function and attention network function were evaluated. The concentrations of serum S100B and NGF in dexmedetomidine group was lower than those in control group (Pfunction scores, attention scores, delayed memory scores, targeted network efficiency and executive control network efficiency in dexmedetomidine group were obviously higher than those in control group (Pcognitive function and attention network function of patients with ischemic cerebrovascular disease have a certain degree of damage, and the preoperative administration of dexmedetomidine can effectively improve the patient's cognitive dysfunction and attention network function after operation.

    To analyze the association between the admission systolic blood pressure (SBP) and 30-day outcome in patients with acute cerebrovascular disease. The REgistro NAcional Mexicano de Enfermedad VAScular Cerebral (RENAMEVASC) is a hospital-based multicenter registry performed between November 2002 and October 2004. A total of 2000 patients with clinical syndromes of acute cerebrovascular disease confirmed by neuroimaging were registered. The modified Rankin scale was used for outcome stratification. We analyzed 1721 patients who had registered their SBP: 78 (4.5%) had transient ischemic attack, 894 (51.9%) brain infarction, 534 (30.9%) intracerebral hemorrhage, 165 (9.6%) subarachnoid hemorrhage and 50 (2.9%) cerebral venous thrombosis. Among 1036 (60.2%) patients with the antecedent of hypertension, only 32.4% had regular treatment. The 30-day case fatality rate presented a J pattern with respect to SBP, so that the risk of death was highest in 65 years (RR: 2.16, IC 95%: 1.74 - 2.67). Both hypotension and significant arterial hypertension at hospital admission are associated with an adverse outcome after acute cerebrovascular disease. Nevertheless, a good functional outcome can be attained in a wide range of SBP.

  6. Cerebrovascular and hypertensive diseases as multiple causes of death in Brazil from 2004 to 2013.

    The proportion of deaths attributed to hypertensive diseases (HYPDs) was only 50% of that registered for cerebrovascular diseases (CBVDs) in 2013 in Brazil. This article aims to evaluate mortality related to HYPDs and CBVDs as multiple causes of death, in Brazil from 2004 to 2013. Analysis of historical series of secondary data obtained from Brazilian official registries. Data about the deaths were obtained from the Mortality Information System of the Brazilian Ministry of Health, available on the DATASUS website. CBVDs and HYPDs were evaluated according to their mentions as the underlying cause of death or entry in any line of the death certificates (DCs), according to their International Statistical Classification of Diseases and Related Health Problems, 10th Revision codes. When CBVDs were the underlying causes of death, HYPDs were mentioned in 40.9% of the DCs. When HYPDs were the underlying causes of death, CBVDs were mentioned in only 5.0%. When CBVDs were mentioned without HYPDs, they were selected as the underlying cause of death 74.4% of the time. When HYPDs were mentioned in DCs without CBVDs, HYPDs were selected 30.0% of the time. In 2004, the frequency of any mention of HYPDs relative to the frequency of HYPDs cited as underlying causes increased fourfold and was followed by a plateau until 2013. In contrast, the frequency of any mention of CBVDs relative to the frequency of CBVDs as underlying causes decreased in the same period. Because this study was based on DC records, it was limited by the way these documents were completed, which may have included lack of record of the causes related to the sequence that culminated in death. When deaths related to HYPDs were evaluated as multiple causes of death, they were mentioned up to four times more often than when they were selected as underlying causes of death. This reinforces the need for better control of hypertension to prevent deaths. Copyright © 2018 The Royal Society for Public Health. Published by

    2010-07-01

    Full Text Available Abstract Background Alzheimer's disease (AD and cerebrovascular disease (CVD including chronic small vessel disease of the brain (SVD are the most frequent causes of dementia. AD is associated with metabolism of amyloid precursor protein (APP and low levels of amyloid-β peptide (Aβ X-42 in the cerebrospinal fluid (CSF. CVD and SVD are established risk factors for AD, brain white matter lesions (WML are established surrogate markers for SVD and are also associated with reduced CSF AβX-42. A cohort survey was performed to examine whether SVD or acute CVD affects APP metabolism and to explore a potential association between WML and APP metabolism in two groups; cognitively impaired patients, subjective and mild (SCI and MCI and stroke patients. Through measurements of CSF APP metabolite levels in patients with a wide range of WML volumes, this study aimed to determine how SVD influences APP metabolism. Methods Sixty-three patients were included: 37 with subjective cognitive impairment (SCI or mild cognitive impairment (MCI without stroke, and 26 after acute stroke. Chronic and acute WML volume and infarct volume were determined by magnetic resonance imaging (MRI post-scan processing, and CSF levels of α- and β-cleaved soluble APP (sAPP-α and sAPP-β, AβX-38, AβX-40 and AβX-42 were determined. The Mann-Whitney test was used to compare the patient groups. Chronic and acute WML volumes, infarct volume, age, and sex were used as predictors for CSF biomarker levels in linear regression analysis. Results CSF levels of sAPP-α and sAPP-β were strongly correlated (r = 0.95, p p p p ≤ 0.005; p ≤ 0.01; p ≤ 0.01; p ≤ 0.05; p ≤ 0.05 respectively, but not with acute WML or infarct volumes. Conclusions Lower CSF levels of sAPP-α and sAPP-β in the stroke group than in the SCI/MCI group and an inverse correlation with chronic WML indicate that ischemia lowers the levels of CSF sAPP metabolites and suggests that APP axonal transport or

    Secondhand smoke causes cardiovascular and respiratory disease. Smoke-free legislation is associated with a lower risk of hospitalization and death from these diseases. Random-effects meta-analysis was conducted by law comprehensiveness to determine the relationship between smoke-free legislation and hospital admission or death from cardiac, cerebrovascular, and respiratory diseases. Studies were identified by using a systematic search for studies published before November 30, 2011 with the use of the Science Citation Index, Google Scholar, PubMed, and Embase and references in identified articles. Change in hospital admissions (or deaths) in the presence of a smoke-free law, duration of follow-up, and law comprehensiveness (workplaces only; workplaces and restaurants; or workplaces, restaurants, and bars) were recorded. Forty-five studies of 33 smoke-free laws with median follow-up of 24 months (range, 2-57 months) were included. Comprehensive smoke-free legislation was associated with significantly lower rates of hospital admissions (or deaths) for all 4 diagnostic groups: coronary events (relative risk, 0.848; 95% confidence interval 0.816-0.881), other heart disease (relative risk, 0.610; 95% confidence interval, 0.440-0.847), cerebrovascular accidents (relative risk, 0.840; 95% confidence interval, 0.753-0.936), and respiratory disease (relative risk, 0.760; 95% confidence interval, 0.682-0.846). The difference in risk following comprehensive smoke-free laws does not change with longer follow-up. More comprehensive laws were associated with larger changes in risk. Smoke-free legislation was associated with a lower risk of smoking-related cardiac, cerebrovascular, and respiratory diseases, with more comprehensive laws associated with greater changes in risk.

    An early diagnosis of the outcome of patients with cerebrovascular disease is important for selecting the optimal treatment strategy. The purpose of this study was to estimate the prognosis of Wallerian degeneration on MRI in stroke patients with hemiparesis. The subjects consisted of 87 stroke patients, 50 hemorrhagic patients and 37 ischemic patients, who were evaluated by MRI at 1 to 6,275 days after stroke onset. Among the 36 patients who were evaluated by consecutive MRI, 161 films were obtained and analyzed. Wallerian degeneration was diagnosed when a small prolonged T2 lesion was seen in the corticospinal tract of the brainstem on at least two contiguous slices. The atrophic rate of the midbrain was calculated as: (the area of the unaffected side of the midbrain - the area of the affected side of the midbrain)/2 x (the area of the unaffected side of the midbrain). The patients' ability to perform the activities of daily living was scored by the Barthel index (BI). Wallerian degeneration in the ipsilateral brainstem was seen for two to three months in 32 cases (37%) and in 58 films (36%) and disappeared about 3 years after the onset of stroke. Wallerian degeneration correlated with the BI scores from 2 to 6 months after stroke (p<0.05), although no relationship was observed at 7 months or later. From 2 to 6 months after stroke, the shrinkage of the midbrain on MRI correlated with the BI scores (p<0.001), although no relationship was observed at 7 months or later. It was therefore both Wallerian degeneration and a shrunken midbrain observed on MRIs, evaluated from 2 to 6 months after stroke were thus suggested to indicate a poor outcome in such patients.

  10. Availability of endovascular therapies for cerebrovascular disease at primary stroke centers.

    Alberts, Mark J; Range, Jean; Spencer, William; Cantwell, Vicki; Hampel, M J

    2017-02-01

    Background Endovascular therapies (EVTs) are useful for treating cerebrovascular disease. There are few data about the availability of such services at primary stroke centers (PSCs). Our hypothesis was that some of these services may be available at some PSCs. Methods We conducted an internet-based survey of hospitals certified as PSCs by the Joint Commission. The survey inquired about EVTs such as intra-arterial (IA) lytics, IA mechanical clot removal, coiling of aneurysms, and cervical arterial stenting, physician training, coverage models, hospital type, and outcomes. Chi-square analyses were used to detect differences between academic and community PSCs. Results Data were available from 352 PSCs, of which 75% were community hospitals, 23% academic medical centers, and 80% were non-profit; almost half (48%) see 300 or more patients annually with ischemic stroke. A majority (60%) provided some or all EVTs on site, while 29% had none on site and no plans to add them. Among the respondents offering EVTs, 95% offered stenting of neck vessels, 86% IA lytics, 80% IA mechanical, and 74% aneurysm coiling. The majority (>55%) that did offer such services provided them 24/7/365. Most endovascular coverage was provided by interventional neuroradiologists (60%), fellowship trained endovascular neurosurgeons (42%), and interventional radiologists (41%). The majority of hospitals (81%) did not participate in an audited national registry. Conclusions A variety of EVT services are offered at many PSCs by interventionalists with diverse types of training. The availability of such services is clinically relevant now with the proven efficacy of mechanical thrombectomy for ischemic stroke.

    Little is known about within-country variation in morbidity and mortality of cerebrovascular diseases (CVDs). Geographic differences in CVD morbidity and mortality have yet to be properly examined. This study examined geographic variation in morbidity and mortality of CVD, neighborhood factors for CVD morbidity and mortality, and the association between CVD morbidity and mortality across the 245 local districts in Korea during 2011-2015. District-level health care utilization and mortality data were obtained to estimate age-standardized CVD morbidity and mortality. The bivariate Pearson correlation was used to examine the linear relationship between district-level CVD morbidity and mortality Z-scores. Simple linear regression and multivariate analyses were conducted to investigate the associations of area characteristics with CVD morbidity, mortality, and discrepancies between morbidity and mortality. Substantial variation was found in CVD morbidity and mortality across the country, with 1074.9 excess CVD inpatients and 73.8 excess CVD deaths per 100,000 between the districts with the lowest and highest CVD morbidity and mortality, respectively. Higher rates of CVD admissions and deaths were clustered in the noncapital regions. A moderate geographic correlation between CVD morbidity and mortality was found (Pearson correlation coefficient = .62 for both genders). Neighborhood level indicators for socioeconomic disadvantages, undersupply of health care resources, and unhealthy behaviors were positively associated with CVD morbidity and mortality and the relative standing of CVD mortality vis-à-vis morbidity. Policy actions targeting life-course socioeconomic conditions, equitable distribution of health care resources, and behavioral risk factors may help reduce geographic differences in CVD morbidity and mortality in Korea.

    Full Text Available Objective To investigate the effect of respiratory function training on respiratory function and conscious state of patients with severe cerebrovascular disease (SCVD.  Methods A total of 27 patients with SCVD were divided into control group (N = 17 and observation group (N = 10. Control group received routine drug and rehabilitation treatment, and observation group was added respiratory function training based on routine treatment. The respiratory rate, tidal volume (TV, heart rate, blood pressure and artery oxygen saturation (SaO2 of patients were monitored by breathing machine before and after 4-week treatment. Meanwhile, arterial blood gas analysis was used to detect arterial partial pressure of oxygen (PaO2, oxygenation index, partial pressure of carbon dioxide (PaCO2 and pH value. At the same time, Glasgow Coma Scale (GCS was used to evaluate the conscious state of patients.  Results All patients successfully completed 4-week rehabilitation training, without asphyxia, arrhythmia or other adverse events. Compared with before training, the respiratory rate (P = 0.006 and pH value (P = 0.010 were significantly decreased, while SaO2 (P = 0.001, oxygenation index (P = 0.000 and GCS scores (P = 0.004, 0.017 were significantly increased in both groups of patients after training. There was no statistically significant difference between 2 groups on respiratory function indexes and GCS scores after training (P > 0.05, for all. Conclusions Respiratory function training did not significantly improve the respiratory function and conscious state of patients with SCVD, yet to be further studied. Randomized controlled clinical trials with larger, layered samples and long-term prognosis observation are needed. Examination method of respiratory function of SCVD patients is also a topic to be explored.  DOI: 10.3969/j.issn.1672-6731.2017.04.007

  13. The value of measurements of the cerebrovascular reserve capacity (CVRC) for the assessment and prognosis of cerebrovascular disease

    1997-01-01

    Today, the diagnostic and therapeutic principles in the management of stroke are changing. Prevention of stroke is one of the major fields of research. One important aim of the newly developed diagnostic techniques is the identification of a particular subgroup of patients with compromised cerebral circulation who will benefit from surgical or medical therapies. The assessment of the CVRC with tracer techniques and the acetazolamide test seem to be a realiable and promising method for this purpose: 1. In carotid artery occlusion, the measurement of CVRV facilitates the identification of a subgroup of patients with compromised CVRC who show an improvement of CVRC after EC-IC bypass surgery. The value of bypass surgery for the prevention of stroke however, has to be confirmed by prospective studies. 2. The benefit from carotid surgery for patients with high-grade carotid stenosis and transient ischemic attack has been convincingly demonstrated by several studies. In asymptomatic patients, however, desobliteration of the carotid artery remains controversial. The identification of asymptomatic cases with compromised CVRC probably contributes to the recognition of patients with a high risk of suffering hemodynamic stroke. 3. In vascular dementia, cerebral blood flow measurements at rest alone have not been useful. CVRC measurements may offer a diagnostic advance in this still not well understood disease. (orig.) [de

    The aim of the present study was to determine the national burden of cerebrovascular diseases in the adult population of Spain. Cross-sectional, descriptive population-based study. We calculated the disability-adjusted life years (DALY) metric using country-specific data from national statistics and epidemiological studies to obtain representative outcomes for the Spanish population. DALYs were divided into years of life lost due to premature mortality (YLLs) and years of life lived with disability (YLDs). DALYs were estimated for the year 2008 by applying demographic structure by sex and age-groups, cause-specific mortality, morbidity data and new disability weights proposed in the recent Global Burden of Disease study. In the base case, neither YLLs nor YLDs were discounted or age-weighted. Uncertainty around DALYs was tested using sensitivity analyses. In Spain, cerebrovascular diseases generated 418,052 DALYs, comprising 337,000 (80.6%) YLLs and 81,052 (19.4%) YLDs. This accounts for 1,113 DALYs per 100,000 population (men: 1,197 and women: 1,033) and 3,912 per 100,000 in those over the age of 65 years (men: 4,427 and women: 2,033). Depending on the standard life table and choice of social values used for calculation, total DALYs varied by 15.3% and 59.9% below the main estimate. Estimates provided here represent a comprehensive analysis of the burden of cerebrovascular diseases at a national level. Prevention and control programmes aimed at reducing the disease burden merit further priority in Spain. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

  15. The Vulnerability of Vessels Involved in the Role of Embolism and Hypoperfusion in the Mechanisms of Ischemic Cerebrovascular Diseases

    Full Text Available Accurate definition and better understanding of the mechanisms of stroke are crucial as this will guide the effective care and therapy. In this paper, we review the previous basic and clinical researches on the causes or mechanisms of ischemic cerebrovascular diseases (ICVD and interpret the correlation between embolism and hypoperfusion based on vascular stenosis and arterial intimal lesions. It was suggested that if there is no embolus (dynamic or in situ emboli, there might be no cerebral infarction. Three kinds of different clinical outcomes of TIA were theoretically interpreted based on its mechanisms. We suppose that there is a correlation between embolism and hypoperfusion, and which mechanisms (hypoperfusion or hypoperfusion induced microemboli playing the dominant role in each type of ICVD depends on the unique background of arterial intimal lesions (the vulnerability of vessels. That is to say, the vulnerability of vessels is involved in the role of embolism and hypoperfusion in the mechanisms of ischemic cerebrovascular diseases. This inference might enrich and provide better understandings for the underlying etiologies of ischemic cerebrovascular events.

    Coronary angiography and brain computed tomography were preoperatively performed to evaluate the clinical condition of coronary artery disease and cerebrovascular disease in 101 patients (mean age, 68.4 years) with revascularization for arteriosclerosis obliterans. Eighty patients had hypertension, 12 had diabetes, and 26 had hyperlipidemia. Seventy-one patients (70.3%) had coronary stenosis. Significant stenoses in major coronary artery branches were confirmed in 35 patients, including 13 patients with old myocardial infarction. Coronary artery bypass grafting and percutaneous coronary angioplasty were performed in 2 and 7 patients with critical stenosis, respectively. Of 57 patients, who underwent brain computed tomography, abnormalities were found in 52 patients (91.2%), including cortical infarction in 9, lacunar infarction in 35, and leukoaraiosis in 27 patients. During the follow-up period 13 patients died (including 3 cases of myocardial infarction and 3 cases of stroke). Actuarial survival rate at 5 years was 80.4%. The influence of ischemic heart disease and cerebrovascular disease on early and late mortality after surgical reconstruction for peripheral occlusive vascular disease is significant. Using visual diagnostic techniques, such as coronary angiography and brain computed tomography, long term survivor should be closely observed for multiple arteriosclerotic vascular diseases.

    Risk factors for vascular cognitive impairment (VCI) are the same as traditional risk factors for cerebrovascular disease (CVD). Early identification of subjects at higher risk of VCI is important for the development of effective preventive strategies. In addition to traditional vascular risk factors (VRF), circulating biomarkers have emerged as potential tools for early diagnoses, as they could provide in vivo measures of the underlying pathophysiology. While VRF have been consistently linked to a VCI profile (i.e., deficits in executive functions and processing speed), the cognitive correlates of CVD biomarkers remain unclear. In this population-based study, the aim was to study and compare cognitive patterns in relation to VRF and circulating biomarkers of CVD. The Barcelona-AsIA Neuropsychology Study included 747 subjects older than 50, without a prior history of stroke or coronary disease and with a moderate to high vascular risk (mean age, 66 years; 34.1% women). Three cognitive domains were derived from factoral analysis: visuospatial skills/speed, verbal memory and verbal fluency. Multiple linear regression was used to assess relationships between cognitive performance (multiple domains) and a panel of circulating biomarkers, including indicators of inflammation, C-reactive protein (CRP) and resistin, endothelial dysfunction, asymmetric dimethylarginine (ADMA), thrombosis, plasminogen activator inhibitor 1 (PAI-1), as well as traditional VRF, metabolic syndrome and insulin resistance (homeostatic model assessment for insulin resistance index). Analyses were adjusted for age, gender, years of education and depressive symptoms. Traditional VRF were related to lower performance in verbal fluency, insulin resistance accounted for lower performance in visuospatial skills/speed and the metabolic syndrome predicted lower performance in both cognitive domains. From the biomarkers of CVD, CRP was negatively related to verbal fluency performance and increasing ADMA

    Findings of cerebral computed tomographies were investigated in 13 patients who did not satisfy the criteria of cerebrovascular Moyamoya disease, but showed the Moyamoya vessels (so-called pseudo-Moyamoya disease). Their ages ranged from 15 to 70 years old. Single patients were diagnosed as having pituitary adenoma after radiation therapy, head trauma, aplastic anemia, and the Rainoud phenomenon, and five as having hypertension. Angiography revealed occlusion and stenosis in the unilateral carotid forks in 7 and 5 patients, respectively. Other appearances included transdural anastomosis via the superficial temporal arteries, the anterior ethmoid arteries, and the collateral pathway from the perforating branches to the cortical branches. Low density areas were seen on CT in 10 patients, seven of whom had multiple areas. Low density areas were seen in the cerebral basal ganglia, watershed zone, and the outer side of the lateral cerebral body, in that order. Four patients had intracranial hemorrhage, subarachnoid hemorrhage, and hemorrhage infarction. Pseudo-Moyamoya disease was sometimes of the incomplete form of the cerebrovascular Moyamoya disease, and attributable to arterial stenosis or constricture due to radiation therapy. (Namekawa, K.).

    Full Text Available Aim: To evaluate the morphological and hemodynamic changes that take place in carotid arteries by colour Doppler in patients presenting with features of stroke. Background and Objectives: Cerebrovascular accidents constitute a major cause of adult mortality. The principal indication for cerebrovascular Doppler examination is stroke prevention. Colour Doppler sonography is a sensitive method for detection of atherosclerotic plaque and provides considerable information about the extent and severity of plaque as well as the resulting diminution of arterial lumen. The main strengths of sonography of carotid arteries are patient comfort, lack of risk and accuracy in detecting carotid stenosis. Material and Methods: A prospective study of Colour Doppler in carotid arteries was carried out for 12 months from 1 st July 2009 to 1 st July 2010. The study was carried out on 40 individuals, suspected of cerebrovascular insufficiency and having one or the other risk factors for cerebrovascular disease. A detailed clinical history, CNS examination findings and evidence of hypertension, diabetes mellitus, hyperlipidemia and ischemic heart disease were noted. Carotid Doppler evaluation was done by using Siemens Antares Ultrasound system. The data gathered were grey scale and Doppler findings of common carotid artery, internal carotid artery and external carotid arteries. Doppler findings were correlated with clinical features and risk factors. Results: In our study of 40 patients, the commonest lesion found was the atherosclerotic plaque. Highest incidence of plaque was seen in males 41% in the age group of 60-70 years and in females 37% in age group of 70-80 years. Cigarette smoking was the most common risk factor (60% associated with stroke/ Transient Ischaemic Attacks (TIA. Hemiparesis was the most common presenting symptom (35% among the symptomatic cases. Atheromatous plaque was most commonly found in the right carotid system (60%. Most common site for

    Oxylipins and fatty acids may be novel therapeutic targets for cardiovascular disease. The objective was to determine if plasma oxylipins or fatty acids can influence the odds of cardiovascular/cerebrovascular events. In 98 patients (25 female, 73 male) with peripheral artery disease, the prevalence of transient ischemic attacks, cerebrovascular accidents, stable angina, and acute coronary syndrome was n = 16, 10, 16, and 24, respectively. Risk factors such as being male, diagnosed hypertension, diabetes mellitus, and hyperlipidemia were not associated with events. Plasma fatty acids and oxylipins were analyzed with gas chromatography and HPLC-MS/MS, respectively. None of 24 fatty acids quantified were associated with events. In contrast, 39 plasma oxylipins were quantified, and 8 were significantly associated with events. These 8 oxylipins are known regulators of vascular tone. For example, every 1 unit increase in Thromboxane B 2 /Prostaglandin F 1 α and every 1 nmol/L increase in plasma 16-hydroxyeicosatetraenoic acid, thromboxane B2, or 11,12-dihydroxyeicosatrienoic acid (DiHETrE) increased the odds of having had ≥2 events versus no event (p < 0.05). The greatest predictor was plasma 8,9-DiHETrE, which increased the odds of acute coronary syndrome by 92-fold. In conclusion, specific oxylipins were highly associated with clinical events and may represent specific biomarkers and (or) therapeutic targets of cardiovascular disease.

    1994-01-01

    The brain perfusion SPECT imaging and functional changes in 27 patients with ischemic cerebrovascular diseases and 20 controls were investigated. Correlated with the clinical findings and MRI study, we discovered the lowered perfusion of Broca and Wernicke area is closely related with the aphasia caused by left basal ganglia infarction. In hemianopia group, as the visual function improved after the light stimulation treatment, the blood perfusion increased in occipital lobe. The lowered perfusion in vestibular center can be observed in vertigo group. From these studies, we concluded that 99m Tc-HMPAO brain SPECT imaging can partly reflect the brain functions

    Single photon emission tomography is, because of its availability and the relatively low costs, the functional imaging modality currently most widely used for clinical applications in the brain. Beside the application of radiopharmaceuticals for the assessment of regional cerebral blood flow there is an increasing clinical use of more selective SPECT-radiopharmaceuticals, like amino acid analogs or receptor ligands. This article gives in its first part a critical review of the clinical applications of SPECT in neuro-oncology, epilepsy, basal ganglia disorders and cerebrovascular disease. (orig.) [de

    2011-01-01

    Purpose: To clarify the differences of the carotid and cerebrovascular disease between patients with and without type 2 diabetes using dual-source CT angiography. Materials and methods: Dual-source CT angiography of the carotid and cerebrovascular arteries was performed in 79 type 2 diabetic patients and 207 non-diabetic patients. The type, extent and distribution of plaques, and luminal stenosis were compared. Results: Compared with non-diabetic patients, diabetic patients had a higher overall incidence of plaque (p 0.05), as well as for the number of diseased segments and the distribution of plaques; both mainly involved the bilateral cavernous segment of the internal carotid artery. As for the stenosis, non-obstructive lesions were more common in diabetic patients (p 0.05). Conclusion: Diabetes is associated with a higher incidence of plaque and non-obstructive stenosis. However, no significant differences were observed in the type, extent and distribution of involved plaques between diabetic and non-diabetic patients.

    Full Text Available Objective: To study associations of cerebrovascular metabolism genotypes and haplotypes with age at Alzheimer’s disease dementia (AD onset and with neuropsychiatric symptoms according to each dementia stage. Methods: Consecutive outpatients with late-onset AD were assessed for age at dementia onset and Neuropsychiatric Inventory scores according to Clinical Dementia Rating scores, apolipoprotein E gene (APOE haplotypes, angiotensin-converting enzyme gene (ACE variants rs1800764 and rs4291, low-density lipoprotein cholesterol receptor gene (LDLR variants rs11669576 and rs5930, cholesteryl ester transfer protein gene (CETP variants I422V and TaqIB, and liver X receptor beta gene (NR1H2 polymorphism rs2695121. Results: Considering 201 patients, only APOE-ɛ4 carriers had earlier dementia onset in multiple correlations, as well as less apathy, more delusions, and more aberrant motor behavior. Both ACE polymorphisms were associated with less intense frontally mediated behaviors. Regarding LDLR variants, carriers of the A allele of rs11669576 had less anxiety and more aberrant motor behavior, whereas carriers of the A allele of rs5930 had less delusions, less anxiety, more apathy, and more irritability. CETP variants that included G alleles of I422V and TaqIB were mostly associated with less intense frontally mediated behaviors, while severely impaired carriers of the T allele of rs2695121 had more anxiety and more aberrant motor behavior. Conclusion: Though only APOE haplotypes affected AD onset, cerebrovascular metabolism genotypes were associated with differences in several neuropsychiatric manifestations of AD.

    The paper presents an analysis of the incidence of cerebrovascular diseases (CeVD) in the cohort of Russian workers involved in recovery tasks after the Chernobyl accident. The studied cohort consists of 53,772 recovery operation workers (liquidators) who arrived in the zone of the Chernobyl accident within the first year after this accident (26 April 1986-26 April 1987). The mean external whole body dose in the cohort was 0.161 Gy, while individual doses varied from 0.0001 Gy to 1.42 Gy. During the follow-up period 1986-2012, a total of 23,264 cases of CeVD were diagnosed as a result of annual health examinations. A Poisson regression model was applied for estimation of radiation risks and for an assessment of other risk factors of CeVD. The following factors were considered as risk factors for CeVD: the dose, duration of the liquidators' work in the Chernobyl zone, and the concomitant diseases (hypertension, ischemic heart disease, atherosclerosis, and diabetes). The baseline incidence of CeVD is statistically significantly (p Chernobyl zone; for those who stayed in the Chernobyl zone less than 6 wk, ERR/Gy = 0.64, 95% CI = (0.38; 0.93), p < 0.001. Among studied concomitant diseases, diabetes mellitus statistically significantly (p = 0.002) increases the radiation risk of CeVD: for liquidators with diagnosed diabetes, ERR/Gy = 1.29.

    This study investigated the relationship between weekly working hours and the occurrence of cerebro-cardiovascular diseases using a case-crossover study design. We investigated average working hours during the 7 days before the onset of illness (hazard period) and average weekly working hours between 8 days and 3 months before the onset of cerebro-cardiovascular diseases (control period) for 1,042 cases from the workers' compensation database for 2009. Among all subjects, the odds ratio by conditional logistic regression for the risk of cerebro-cardiovascular diseases with a 10 hr increase in average weekly working hours was 1.45 (95% confidence interval [CI]: 1.22-1.72), a significant association. An increase in average weekly working hours may trigger the onset of cerebro-cardiovascular disease. Am. J. Ind. Med. 60:753-761, 2017. © 2017. Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    1979-01-01

    Evidence of cerebrovascular disease at autopsy was compared in two groups of men, 186 long time residents of Hiroshima, Japan and 253 men of Japanese ancestry long resident in Honolulu, Hawaii. They were from 45 to 71 years of age at death. Atherosclerosis of the circle of Willis and its major branches, sclerosis of the intraparenchymal arteries and the frequency of cerebral hemorrhage and cerebral infarct were compared in the two populations. The Honolulu subjects had significantly more atherosclerosis of the circle of Willis, but less intraparenchymal artery sclerosis and less cerebral infarction. Cerebral hemorrhage was equally frequent in the two cities. It was concluded that cerebral infarction is more frequent in Japanese men in Hiroshima than Honolulu, and that men of Japanese ancestry in Honolulu are spared an appreciable risk of cerebral infarction through decreased frequency of intraparenchymal arterial sclerosis despite higher levels of atherosclerosis of large intracranial arteries.

    Full Text Available Scutellarein, the main metabolite of scutellarin in vivo, has relatively better solubility, bioavailability and bio-activity than scutellarin. However, it is very difficult to obtain scutellarein in nature compared with scutellarin. Therefore, the present study focused on establishing an efficient route for the synthesis of scutellarein by hydrolyzing scutellarin. The in vitro antioxidant activities of scutellarein were evaluated by measuring its scavenging capacities toward DPPH, ABTS+•, •OH free radicals and its protective effect on H2O2-induced cytotoxicity in PC12 cells using MTT assay method. The results showed that essential point to the synthesis was the implementation of H2SO4 in 90% ethanol in N2 atmosphere; scutellarein had stronger antioxidant activity than scutellarin. The results have laid the foundation for further research and the development of scutellarein as a promising candidate for ischemic cerebrovascular disease.

    The scientific community faces important discussions on the validity of the linear no-threshold (LNT) model for radiation-associated cardiovascular diseases at low and moderate doses. In the present study, mortalities from cerebrovascular diseases (CeVD) and heart diseases from the latest data on atomic bomb survivors were analyzed. The analysis was performed with several radio-biologically motivated linear and nonlinear dose-response models. For each detrimental health outcome one set of models was identified that all fitted the data about equally well. This set was used for multi-model inference (MMI), a statistical method of superposing different models to allow risk estimates to be based on several plausible dose-response models rather than just relying on a single model of choice. MMI provides a more accurate determination of the dose response and a more comprehensive characterization of uncertainties. It was found that for CeVD, the dose-response curve from MMI is located below the linear no-threshold model at low and medium doses (0-1.4 Gy). At higher doses MMI predicts a higher risk compared to the LNT model. A sublinear dose-response was also found for heart diseases (0-3 Gy). The analyses provide no conclusive answer to the question whether there is a radiation risk below 0.75 Gy for CeVD and 2.6 Gy for heart diseases. MMI suggests that the dose-response curves for CeVD and heart diseases in the Lifespan Study are sublinear at low and moderate doses. This has relevance for radiotherapy treatment planning and for international radiation protection practices in general. (orig.)

    HIV-associated neurocognitive disorders (HAND) remain prevalent in the combined antiretroviral therapy (CART) era, especially the milder forms. Despite these milder phenotypes, we have shown that motor abnormalities persist and have quantified them with the HIV Dementia Motor Scale (HDMS). Our objectives were to replicate, in an independent sample, our prior findings that the HDMS is associated with cognitive impairment in HIV, while adding consideration of age-associated comorbidities such as cerebrovascular disease, and to examine the longitudinal trajectories of cognitive and motor dysfunction. We included all participants enrolled in the Manhattan HIV Brain Bank (MHBB) from January 2007 to May 2017 who had complete baseline data (N = 164). MHBB participants undergo standardized longitudinal assessments including documentation of comorbidities and medications, blood work, the HDMS, and neurocognitive testing. We found that motor dysfunction, cognitive impairment, and cerebrovascular disease were significantly associated with each other at baseline. Cerebrovascular disease independently predicted cognitive impairment in a multivariable model. Longitudinal analysis in a subset of 78 participants with ≥ 4 years of follow-up showed a stable cognition but declining motor function. We conclude that the HDMS is a valid measurement of motor dysfunction in HIV-infected patients and is associated with cognitive impairment and the presence of cerebrovascular disease. Cognitive impairment is mild and stable in CART-treated HIV; however, motor function declines over time, which may be related to the accrual of comorbidities such as cerebrovascular disease. Further research should examine the mechanisms underlying motor dysfunction in HIV and its clinical impact.

  4. Vascular remodeling versus amyloid beta-induced oxidative stress in the cerebrovascular dysfunctions associated with Alzheimer's disease.

    2005-11-30

    The roles of oxidative stress and structural alterations in the cerebrovascular dysfunctions associated with Alzheimer's disease (AD) were investigated in transgenic mice overexpressing amyloid precusor protein (APP+) or transforming growth factor-beta1 (TGF+). Age-related impairments and their in vitro reversibility were evaluated, and underlying pathogenic mechanisms were assessed and compared with those seen in AD brains. Vasoconstrictions to 5-HT and endothelin-1 were preserved, except in the oldest (18-21 months of age) TGF+ mice. Despite unaltered relaxations to sodium nitroprusside, acetylcholine (ACh) and calcitonin gene-related peptide-mediated dilatations were impaired, and there was an age-related deficit in the basal availability of nitric oxide (NO) that progressed more gradually in TGF+ mice. The expression and progression of these deficits were unrelated to the onset or extent of thioflavin-S-positive vessels. Manganese superoxide dismutase (SOD2) was upregulated in pial vessels and around brain microvessels of APP+ mice, pointing to a role of superoxide in the dysfunctions elicited by amyloidosis. In contrast, vascular wall remodeling associated with decreased levels of endothelial NO synthase and cyclooxygenase-2 and increased contents of vascular endothelial growth factor and collagen-I and -IV characterized TGF+ mice. Exogenous SOD or catalase normalized ACh dilatations and NO availability in vessels from aged APP+ mice but had no effect in those of TGF+ mice. Increased perivascular oxidative stress was not evidenced in AD brains, but vascular wall alterations compared well with those seen in TGF+ mice. We conclude that brain vessel remodeling and associated alterations in levels of vasoactive signaling molecules are key contributors to AD cerebrovascular dysfunctions.

    Treatment with statin may be beneficial for patients with chronic kidney disease (CKD). However, the debate over the clinical importance of statin in patients with predialysis advanced CKD remains unresolved. The objective of the article was to evaluate the effect of statin on mortality, cerebrovascular, and renal outcomes in patients with predialysis advanced CKD and dyslipidemia. Data on predialysis advanced CKD patients were retrieved from the National Health Insurance Research Database based on the guidelines for prescribing regular erythropoietin-stimulating agent in CKD patients. Patients with dyslipidemia were further selected and divided into 2 groups by their statin use after the prescribed erythropoietin-stimulating agent. All-cause mortality and cerebrovascular and renal outcomes were analyzed after propensity score matching. There were 2016 and 14,412 patients in the statin and nonstatin groups. Their average follow-up periods were 3.7 and 3.0 years, respectively. After 1:2 propensity score matching, the annual all-cause mortality rate was higher in the nonstatin than in the statin group (143.99 vs 109.50 per 1000 person-years; P statin group (1269.45 vs 1095.00 per 1000 person-years; P = .002). Adverse events were not significant between the 2 groups. Statins may reduce the all-cause mortality and reduced the risk of dialysis in patients with predialysis advanced CKD and dyslipidemia. However, statins have no impact on ischemic-hemorrhage stroke. Copyright © 2016 National Lipid Association. Published by Elsevier Inc. All rights reserved.

    It is unclear whether isolated cutaneous lupus erythematosus (CLE) affects cardiovascular risk. We estimated the cumulative incidence and mortality of cardiovascular diseases in a population-based CLE cohort and compared the risk with a matched non-CLE cohort. All incident cases of CLE in Olmsted County, Minnesota, between 1965 and 2005 were followed until December 2013. The cumulative incidence of cerebrovascular accidents (CVAs [including stroke and transient ischemic attack]), ischemic heart disease (IHD [including coronary artery disease, myocardial infarction, and angina pectoris]), heart failure, and peripheral arterial disease (PAD) was derived and compared to an age-, sex-, and calendar year-matched non-CLE cohort using Cox models. There were 155 patients with CLE (mean ± SD age at diagnosis 48 ± 16 years, 65% female, mean ± SD BMI 26.3 ± 7.1 kg/m 2 , 40% smokers, 9% with diabetes mellitus). During a median followup of 14.6 years, 41 CLE patients had cardiovascular events (15 patients with CVAs, 32 patients with IHD), with a 20-year cumulative incidence of 31.6%. As compared to non-CLE subjects, the risk of CVAs (smoking-adjusted hazard ratio [HR] 2.97 [95% confidence interval (95% CI) 1.13-7.78]) and PAD (HR 2.06 [95% CI 0.99-4.32]) was increased in patients with CLE, but the risk of IHD was not increased (HR 0.94 [95% CI 0.57-1.54]). There was no increase in cardiovascular mortality (HR 1.68 [95% CI 0.76-3.75]). The magnitude of risk for any cardiovascular outcome was not significantly influenced by the extent of cutaneous involvement. CLE may be associated with an increased risk of CVAs and PAD, but not IHD. Factors contributing to increased CVA risk in patients with CLE merit evaluation. © 2016, American College of Rheumatology.

  7. Positron emission tomography in cerebrovascular disease: The relationship between regional cerebral blood flow, blood volume and oxygen metabolism

    Herold, S.

    1985-03-01

    Positron emission tomography in cerebrovascular disease has demonstrated the importance of the relationship between regional cerebral blood flow and the cerebral metabolic activity. In acute stroke it has been found that within the first hours after the onset of symptoms cerebral blood flow in the affected area is more depressed than cerebral oxygen utilisation. This relative preservation of oxygen utilisation results from an increase in the oxygen extraction ratio far above its normal value. However, the oxygen extraction fraction subsequently falls in the following days indicating the transition from a situation of possibly reversible ischaemia to irreversible infarction. In patients with carotid occlusive disease an increase in the oxygen extraction ratio has been observed only in very few cases. It has been shown, however, that at an earlier stage the relationship between CBF and CBV (as CBF/CBV-ratio) provides a sensitive measure of diminished perfusion pressure which could be helpful for the selection of patients for EC-IC bypass surgery. In patients with sickle cell anaemia it has been found that oxygen delivery to the brain is maintained by an increase in cerebral blood flow, whereas the oxygen extraction ratio is not increased despite the presence of a low oxygen affinity haemoglobin. Preliminary observations in classical migraine suggest an ischaemic situation during the attack.

  8. Risk of cerebrovascular accidents and ischemic heart disease in patients with inflammatory bowel disease: a systematic review and meta-analysis.

    2014-03-01

    Inflammatory bowel disease (IBD) is associated with an increased risk of venous thromboembolic disease. However, it is unclear whether IBD modifies the risk of arterial thromboembolic events, including cerebrovascular accidents (CVA) and ischemic heart disease (IHD). We performed a systematic review and meta-analysis of cohort and case-control studies that reported incident cases of CVA and/or IHD in patients with IBD and a non-IBD control population (or compared with a standardized population). We calculated pooled odds ratios (ORs) with 95% confidence intervals (CIs). We analyzed data from 9 studies (2424 CVA events in 5 studies, 6478 IHD events in 6 studies). IBD was associated with a modest increase in the risk of CVA (5 studies; OR, 1.18; 95% CI, 1.09-1.27), especially among women (4 studies; OR, 1.28; 95% CI, 1.17-1.41) compared with men (OR, 1.11; 95% CI, 0.98-1.25), and in young patients (<40-50 y old). The increase in risk was observed for patients with Crohn's disease and in those with ulcerative colitis. IBD also was associated with a 19% increase in the risk of IHD (6 studies; OR, 1.19; 95% CI, 1.08-1.31), both in patients with Crohn's disease and ulcerative colitis. This risk increase was seen primarily in women (4 studies; OR, 1.26; 95% CI, 1.18-1.35) compared with men (OR, 1.05; 95% CI, 0.92-1.21), in young and old patients. IBD was not associated with an increased risk of peripheral arterial thromboembolic events. Considerable heterogeneity was observed in the overall analysis. IBD is associated with a modest increase in the risk of cardiovascular morbidity (from CVA and IHD)-particularly in women. These patients should be counseled routinely on aggressive risk factor modification. Copyright © 2014 AGA Institute. Published by Elsevier Inc. All rights reserved.

    Among patients receiving clopidogrel for coronary artery disease, concomitant therapy with proton pump inhibitors (PPIs) has been associated with an increased risk for recurrent coronary events. Factores de Riesgo y ENfermedad Arterial (FRENA) is an ongoing, multicenter, observational registry of consecutive outpatients with coronary artery disease, cerebrovascular disease, or peripheral artery disease. We retrospectively examined the influence of concomitant use of PPIs on outcome in patients receiving clopidogrel. As of March 2009, 1222 patients were using clopidogrel: 595 had coronary artery disease, 329 cerebrovascular disease, and 298 had peripheral artery disease. Of these, 519 (42%) were concomitantly using PPIs. Over a mean follow-up of 15 months, 131 patients (11%) had 139 subsequent ischemic events: myocardial infarction 44, ischemic stroke 40, and critical limb ischemia 55. Seventeen of them (13%) died within 15 days of the subsequent event. PPI users had a higher incidence of myocardial infarction (rate ratio, 2.5; 95% confidence interval [CI], 1.3-4.8), ischemic stroke (rate ratio, 1.9; 95% CI, 1.03-3.7), and a nonsignificantly higher rate of critical limb ischemia (rate ratio, 1.6; 95% CI, 0.95-2.8) than nonusers. On multivariate analysis, concomitant use of clopidogrel and PPIs was independently associated with an increased risk for subsequent ischemic events both in the whole series of patients (hazard ratio, 1.8; 95% CI, 1.1-2.7) and in those with cerebrovascular disease or peripheral artery disease (hazard ratio, 1.5; 95% CI, 1.01-2.4). In patients with established arterial disease, concomitant use of PPIs and clopidogrel was associated with a nearly doubling of the incidence of subsequent myocardial infarction or ischemic stroke. This higher incidence persisted after multivariate adjustment.

    Knapp, W.H. (Herzzentrum Nordrhein-Westfalen, Bad Oeynhausen (Germany). Inst. fuer Nuklearmedizin)

    1993-02-01

    Investigations using recently emerged perfusion tracers for SPECT, Tc-99m-HMPAO in particular, and studies of local glucose metabolism and oxygen utilisation with PET have deepened our knowledge of the pathophysiology in development and in the sequel of stroke. Studies of local cerebral blood flow and cerebrovascular reserve capacity are indicated in case of neurological symptoms suspected to be caused by transient ischemic attacks or in case of significant narrowing of the cerebral arteries. PET investigations of local metabolism (at the present state) are indicated in patients with incompleted stroke or with infarction and extended ischemic border zone. The differential diagnosis between multi-infarct-dementia and primarily neurodegenerative dementias is facilitated, in some individuals, by the characteristic topography of reduced flow. (orig./MG).

  13. The value of brain scanning in cerebro-vascular disease by CT

    Huber, G.; Emde, H.

    1980-01-01

    Brain scanning by scintigraphy and CT studies of the brain are complementary methods. The precise demonstration of the anatomy and the pathology of the brain by CT is supplemented by brain scintigraphy due to the latter's value to assess the hemodynamic properties of a lesion and thus provide important clues to its site and sometimes even its histology. This is especially true in vascular brain disease thus either dispensing the need for an invasive procedure such as angiography or providing information for a specific approach.

We present a system for extracting disease-gene associations from biomedical abstracts. The system consists of a highly efficient dictionary-based tagger for named entity recognition...... of human genes and diseases, which we combine with a scoring scheme that takes into account co-occurrences both within and between sentences. We show that this approach is able to extract half of all manually curated associations with a false positive rate of only 0.16%. Nonetheless, text mining should...... not stand alone, but be combined with other types of evidence. For this reason, we have developed the DISEASES resource, which integrates the results from text mining with manually curated disease-gene associations, cancer mutation data, and genome-wide association studies from existing databases...

  15. Effects of weather variability and air pollutants on emergency admissions for cardiovascular and cerebrovascular diseases.

    Hori, Aya; Hashizume, Masahiro; Tsuda, Yoko; Tsukahara, Teruomi; Nomiyama, Tetsuo

    2012-01-01

    We examined the effect of ambient temperature, air pressure and air pollutants on daily emergency admissions by identifying the cause of admission for each type of stroke and cardiovascular disease using generalized linear Poisson regression models allowing for overdispersion, and controlling for seasonal and inter-annual variations, days of the week and public holidays, levels of influenza and respiratory syncytial viruses. Every 1°C decrease in mean temperature was associated with an increase in the daily number of emergency admissions by 7.83% (95% CI 2.06-13.25) for acute coronary syndrome (ACS) and heart failure, by 35.57% (95% CI 15.59-59.02) for intracerebral haemorrhage (ICH) and by 11.71% (95% CI 4.1-19.89) for cerebral infarction. An increase of emergency admissions due to ICH (3.25% (95% CI 0.94-5.51)), heart failure (3.56% (95% CI 1.09-5.96)) was observed at every 1 hPa decrease in air pressure from the previous days. We found stronger detrimental effect of cold on stroke than cardiovascular disease.

  16. Deaths from cerebrovascular diseases correlated to month of birth: elevated risk of death from subarachnoid hemorrhage among summer-born

    Nonaka, K.; Imaizumi, Y.

    It has been suggested that maternal nutrition, and fetal and infant growth have an important effect on the risk of cardiovascular disease in adult life. We investigated the population-based distribution of deaths from cerebrovascular diseases (ICD9 codes 430, 431, or 434) in Japan in 1986-1994 as a function of birth month, by examining death-certificate records. For a total of 853 981 people born in the years 1900-1959, the distribution of the number of deaths according to the month of birth was compared with the distribution expected from the monthly numbers of all births for each sex and for the corresponding birth decade. For those born between 1920 and 1949, there were significant discrepancies between the actual numbers of deaths from subarachnoid hemorrhage (ICD9 430) and the numbers expected, and these differences were related to the month of birth. Those born in summer, June-September, consistently had an elevated risk of death, particularly men, where the excess risk was 8%-23%. This tendency was also observed, less distinctly but significantly, for deaths from intracerebral hemorrhage (ICD9 431), but was not observed for those dying from occlusion of the cerebral arteries (ICD9 434). The observation that the risk of dying from subarachnoid hemorrhage was more than 10% higher among those born in the summer implies that at least one in ten deaths from subarachnoid hemorrhage has its origin at a perinatal stage. Although variations in hypertension in later life, which could possibly be ''programmed'' during the intra-uterine stages, could be an explanation for this observation, the disease-specific nature of the observation suggests the involvement of aneurysm formation, which is a predominant cause of subarachnoid hemorrhage.

    Full Text Available Background: Alzheimer’s disease (AD is a neurodegenerative disorder that may benefit from early diagnosis and intervention. Therefore, there is a need to identify early biomarkers of AD using non-invasive techniques such as functional magnetic resonance imaging (fMRI. Recently, novel approaches to the analysis of resting-state fMRI data have been developed that focus on the moment-to-moment variability in the blood oxygen level dependent (BOLD signal. The objective of the current study was to investigate BOLD variability as a novel early biomarker of AD and its associated psychophysiological correlates.Method: Data were obtained from the Alzheimer’s Disease Neuroimaging Initiative (ADNI 2 database from 19 participants with AD and 19 similarly aged controls. For each participant, a map of BOLD signal variability (SDBOLD was computed as the standard deviation of the BOLD timeseries at each voxel. Group comparisons were performed to examine global differences in resting state SDBOLD in AD versus healthy controls. Correlations were then examined between participant SDBOLD maps and (1 ADNI-derived composite scores of memory and executive function and (2 neuroimaging markers of cerebrovascular status.Results: Between-group comparisons revealed significant (p < 0.05 increases in SDBOLD in patients with AD relative to healthy controls in right-lateralized frontal regions. Lower memory scores and higher WMH burden were associated with greater SDBOLD in the healthy control group (p < 0.1, but not individuals with AD.Conclusion: The current study provides proof of concept of a novel resting state fMRI analysis technique that is non-invasive, easily accessible, and clinically compatible. To further explore the potential of SDBOLD as a biomarker of AD, additional studies in larger, longitudinal samples are needed to better understand the changes in SDBOLD that characterize earlier stages of disease progression and their underlying psychophysiological

    Full Text Available OBJECTIVE: If the present data defining the prognostic predictors is examined carefully, a serious contradiction is noticed. In this study, we tried to determine which factors affect the sixth month mortality, recurrence and functional recovery measured quantitatively after ischemic stroke, among our own patients followed in a tertiary health care center. METHODS: Age, sex, the presence of hypertension, coronary heart disease, atrial fibrillation, diabetes mellitus, hyperlipidemia, previous stroke, stroke subtype, admittance mean blood pressure, admittance blood sugar, hemotocrit, the presence of left ventricle hypertrophy and ejection fraction was recorded for 223 patients with ischemic stroke. The scores for National Institute of Health Stroke Scale (NIHSS, modified Rankin Scale (mRS and Barthel Index (BI were recorded at the beginning and at the end of six months. The correlation of these 14 clinical and laboratory parameters with mortality, recurrence and recovery was examined statistically. RESULTS: Mortality rate was 33%, recurrence rate was 3.8%. Factors related with mortality were age, female gender, coronary artery disease, atrial fibrillation, low ejection fraction, low hematocrit and high admittance blood glucose (p 0.05. In the multivariate analyses, only, the effect of age, gender and hyperlipidemia on mortality was persisting (p< 0.05. Considering NIHSS, patients with high mean admittance blood pressure, considering mRS and BI younger patients and patients with lacunar infarcts had better recovery levels, while patients with previous strokes had poorer recovery (p< 0.05. CONCLUSION: Higher age and high admittance blood sugar were the most important determinants of mortality after ischemic stroke. Hyperlipidemia reduces the risk of death after stroke probably because of the neuroprotective effects of lipid lowering drugs. None of these parameters clearly affect functional recovery at the end of six month

    Technetium-labeled hexamethyl-propyleneamineoxime (HM-PAO) is a promising radiopharmaceutical for the demonstration of cerebral blood flow. Twenty-four patients who had experienced either acute stroke (AS) or transient ischemic attack (TIA) were studied by x-ray CT and SPECT using technetium-labeled HM-PAO total of 26 studies. HM-PAO has a cerebral distribution similar to that of iodoamphetamine, but labeling with technetium allows good SPECT imaging on demand in any nuclear medicine department. In ten of the 16 patients who had experienced AS, findings on HM-PAO and CT studies correlated well. In six patients reduced cortical perfusion was detected on HM-PAO imaging, but only small infarcts in the internal capsule were seen on CT. In four of the eight patients who had experienced TIA, neither study revealed any abnormality. In the remaining four, areas of cortical underperfusion were seen on HM-PAO imaging, whereas the CT examination was normal. The findings in this study suggest that HM-PAO imaging is a more sensitive method for demonstrating the extent of cerebral underperfusion in cases of cerebrovascular accident

  1. Characterization of Peripheral Immune Cell Subsets in Patients with Acute and Chronic Cerebrovascular Disease: A Case-Control Study

    Full Text Available Immune cells (IC play a crucial role in murine stroke pathophysiology. However, data are limited on the role of these cells in ischemic stroke in humans. We therefore aimed to characterize and compare peripheral IC subsets in patients with acute ischemic stroke/transient ischemic attack (AIS/TIA, chronic cerebrovascular disease (CCD and healthy volunteers (HV. We conducted a case-control study of patients with AIS/TIA (n = 116 or CCD (n = 117, and HV (n = 104 who were enrolled at the University Hospital Würzburg from 2010 to 2013. We determined the expression and quantity of IC subsets in the three study groups and performed correlation analyses with demographic and clinical parameters. The quantity of several IC subsets differed between the AIS/TIA, CCD, and HV groups. Several clinical and demographic variables independently predicted the quantity of IC subsets in patients with AIS/TIA. No significant changes in the quantity of IC subsets occurred within the first three days after AIS/TIA. Overall, these findings strengthen the evidence for a pathophysiologic role of IC in human ischemic stroke and the potential use of IC-based biomarkers for the prediction of stroke risk. A comprehensive description of IC kinetics is crucial to enable the design of targeted treatment strategies.

    Cerebral vascular reserve can be assessed by development of collateral channels (DCC) on cerebral angiography(CA) or vasoreactivity (VR) on acetazolamide-enhanced brain SPECT (ACZ-SPECT). The purpose of this study was to compare Tc-99m ECD ACZ-SPECT with CA in the evaluation of vascular reserve in patients (pts) with cerebrovascular disease(CVD). Twenty seven patients with CVD, including TIA (n=13), infarction (n=11) and asymptomatic pts (AS, n=3), underwent CA and ACZ-SPECT. Basal and ACZ-SPECT was obtained consecutively, and image subtraction was performed. On CA, degree of DCC was scored 0-3 (0: normal, 3: poor) according to parenchymal staining on delayed film. In ACZ-SPECT, decrease of VR was graded 0-3 (0: normal, 3: more than 30% decrease). The correlation between degree of stenosis, DCC and VR were analyzed. 1) Variable degree of VR or DCC was observed in totally occluded or stenotic cerebral arterial territories. 2) In arterial territories with poor DCC, ACZ-SPECT showed poor VR. However, in 5 out of 11 TIA or AS with good DCC, poor VR was observed. These data suggests that 1) cerebral hemodynamic status cannot be assessed by the degree of stenosis on CA alone. 2) DCC may overestimate the cerebral vascular reserve in patients with TIA or AS. 3) ACZ-SPECT plays a complementary role to CA for evaluation of cerebral hemodynamic status in pts with CVD

    15 patients with cerebral infarctions involving major vessels, such as internal carotid and middle cerebral arteries, were studied sequentially with a 0.5 Tesla superconductive MRI system from a few hours after the insults up to 3 months. Within 24 hours after the events, high-signal areas were detected in 13 of the 15 cases by the use of T/sub 2/-weighted images. The high-signal areas were noted in two out of three cases even within 3 hours, and in one out of two within six hours, after the cerebrovascular accidents, whereas no abnormalities were noted by conventional CT scans within the same times. There was a tendency for the high-signal areas to be localized in the cortical and deep gray matter within 24 hours and to extend into the deep white matter during the following 24 hours. It was suggested that the localization of high-signal areas in the gray matter in the early ischemic phase could be due to cytotoxic edema and that there was a different vulnerability to ischemia between gray and white matter. At 2 weeks after the accidents, a ''fogging effect'' was noted in five out of the eight cases which were sequentially evaluated by MRI. MRI was superior to CT scan in the visualization of this ''fogging effect''. All of the 5 cases with cortical-subcortical infarctions showed the ''fogging effect'', whereas 3 cases with deep gray matter infarctions, in which the collateral circulation was poor angiographically, did not show such a phenomenon. The CT scans revealed no findings which suggested a hemorrhagic infarction in any of the 5 cases with the ''fogging effect''. These findings suggested that the ''fogging effect'' could represent the reflow phenomenon from collateral circulations.

    Chronic exercise has been shown to prevent or slow age-related decline in cognitive functions in otherwise healthy, asymptomatic individuals. We sought to assess cognitive function in a stable coronary heart disease (CHD) sample and its relationship to cerebral oxygenation-perfusion, cardiac hemodynamic responses, and [Formula: see text] peak compared to age-matched and young healthy control subjects. Twenty-two young healthy controls (YHC), 20 age-matched old healthy controls (OHC) and 25 patients with stable CHD were recruited. Cognitive function assessment included short term-working memory, perceptual abilities, processing speed, cognitive inhibition and flexibility and long-term verbal memory. Maximal cardiopulmonary function (gas exchange analysis), cardiac hemodynamic (impedance cardiography) and left frontal cerebral oxygenation-perfusion (near-infra red spectroscopy) were measured during and after a maximal incremental ergocycle test. Compared to OHC and CHD, YHC had higher [Formula: see text] peak, maximal cardiac index (CI max), cerebral oxygenation-perfusion (ΔO2 Hb, ΔtHb: exercise and recovery) and cognitive function (for all items) (Pcognitive inhibition and flexibility and long-term verbal memory (Pcognitive function (Pcognitive function (Pcognitive function, a similar cerebral oxygenation/perfusion during exercise but reduced one during recovery vs. their aged-matched healthy counterparts.

    2014-02-01

    Whereas statins and acetylsalicylic acid (ASA) are considered gold standard for secondary prevention following myocardial infarction or atherotrombotic stroke, there are inconsistent data on the use of these drugs for primary prevention in patients with increased cardiovascular risk. Some meta-analyses indicated that the use of statins and ASA for primary prevention of cardiovascular disease can reduce the risk of cardiovascular events such as ischemic stroke or myocardial infarction. However, the effects of primary prevention with statins and ASA on mortality varied in the data included in these meta-analyses. Therefore the guidelines of the German College of General Practitioners and Family Physicians recommend primary prevention with statins and ASA only in those patients who have a 10-year risk of cardiovascular events which exceeds 20 %. Divergently, primary prevention with ASA is not recommended by the European Society of Cardiology. Observational studies suggested that treatment success of primary prevention with statins and ASA depends on various factors such as adherence to medication and prescription behavior of physicians. This review summarizes the current literature on primary prevention of cardiovascular events with ASA and statins. © Georg Thieme Verlag KG Stuttgart · New York.

    Air pollution is associated with a broad range of adverse health effects, including mortality and morbidity due to cardio- and cerebrovascular diseases (CCVD), but the molecular mechanisms involved are not entirely understood. This study aims to investigate the involvement of oxidative stress and inflammation in the causal chain, and to identify intermediate biomarkers that are associated retrospectively with the exposure and prospectively with the disease. We designed a case-control study on CCVD nested in a cohort of 18,982 individuals from the EPIC-Italy study. We measured air pollution, inflammatory biomarkers, and whole-genome DNA methylation in blood collected up to 17 years before the diagnosis. The study sample includes all the incident CCVD cases among former- and never-smokers, with available stored blood sample, that arose in the cohort during the follow-up. We identified enrichment of altered DNA methylation in "ROS/Glutathione/Cytotoxic granules" and "Cytokine signaling" pathways related genes, associated with both air pollution (multiple comparisons adjusted p for enrichment ranging from 0.01 to 0.03 depending on pollutant) and with CCVD risk (P = 0.04 and P = 0.03, respectively). Also, Interleukin-17 was associated with higher exposure to NO 2 (P = 0.0004), NO x (P = 0.0005), and CCVD risk (OR = 1.79; CI 1.04-3.11; P = 0.04 comparing extreme tertiles). Our findings indicate that chronic exposure to air pollution can lead to oxidative stress, which in turn activates a cascade of inflammatory responses mainly involving the "Cytokine signaling" pathway, leading to increased risk of CCVD. Inflammatory proteins and DNA methylation alterations can be detected several years before CCVD diagnosis in blood samples, being promising preclinical biomarkers. Environ. Mol.

On phase image of susceptibility-weighted imaging and regions of interest were manually drawn at the bilateral head of the caudate nucleus, lenticular nucleus (LN, thalamus (TH, frontal white matter, and occipital white matter. The correlation between iron deposition level and the clinical and imaging variables was also investigated.Results: Iron deposition level at LN was significantly higher in patients with previous stroke history. It linearly correlated with the presence and number of cerebral microbleeds (CMBs but not with white matter hyperintensity and lacunar infarct. Multiple linear regression analysis showed that deep structure CMBs were the most relevant in terms of iron deposition at LN.Conclusion: Iron deposition at LN may increase in cases of more severe ischemia in aged patients with transient ischemic attack, and it may be an imaging marker for CMB of ischemic origin.

    The incidence of gallbladder sludge or gallstone formation in bedridden patients with cerebrovascular disease (CVD) remains obscure. The aim of this study was to determine the incidence, relationship to feeding method, and mechanisms of gallbladder sludge and gallstone formation in elderly patients with CVD. Using ultrasonography, we determined the development of gallbladder sludge and gallstone over a 12-month period, the area of the gallbladder, the gallbladder contractile response to cerulein, and fasting levels of plasma cholecystokinin (CCK) in 40 bedridden elderly patients with CVD. The patients were divided into three groups based on the feeding method: oral ingestion (OI), nasogastric feeding (NF), and total parenteral nutrition (TPN). Gallbladder sludge and gallstone were not observed in any of the 14 OI patients, but occurred in 6 and 1 of the 11 NF patients, and in 14 and 3 of the 15 TPN patients, respectively. Fasting gallbladder areas were significantly larger in the TPN group than in the other two groups. The TPN group showed a marked decrease in cerulein-induced gallbladder contractility. Fasting plasma CCK levels were lower in the TPN group than in the OI group. Our results indicate that elderly patients with CVD confined to bed over long periods are not necessarily at risk of gallbladder sludge or gallstone formation, and the development of these features may be associated with the feeding method. The predisposition of CVD patients on TPN to gallbladder disease is probably caused by failure of gallbladder contraction, resulting from insufficient secretion of CCK and impaired sensitivity of the gallbladder to CCK.

    The aim of this study was to obtain an estimate of the incidence of cerebrovascular disease (CVD) in the Spanish population in 2002. The study involved data on patients aged over 24 years for the year 2002 contained in both the death register and the Minimum Basic Data Set from 65 of the 84 Catalan general hospitals (i.e., 90.7% of all acute hospital beds in Catalonia). Total and age-adjusted mortality rates, cumulative incidence, and hospitalization rates, and the 28-day case fatality rate for CVD in the Catalan population were calculated after cases of traumatic and transient disease had been excluded. The unadjusted CVD mortality rate per 100,000 population aged over 24 years in Catalonia was 92 in men and 119 in women. The age-adjusted rates were 58 (95% confidence interval or CI, 56-61) and 43 (95% CI, 41-44), respectively. The cumulative incidence of CVD per 100,000 population was 218 (95% CI, 214-221) in men and 127 (95% CI, 125-128) in women. The unadjusted 28-day case fatality rate in the population was 36.2%: 30.3% in men and 42.0% in women. Some 62.5% of patients (57.2% of men and 66.4% of women) died from CVD outside hospital. These findings indicate that CVD mortality and incidence rates in Catalonia are among the lowest in developed countries. More than half of the deaths that took place within 28 days after the onset of symptoms occurred outside hospital.

Associations between mortality and mean apparent temperature and minimum apparent temperature (average for lags 0–15 were studied using Poisson regression controlling for barometric pressure (average for lags 0–3, wind speed and effects of month, year, weekends and holidays. Analyses were repeated using mean and minimum temperatures. Results. Overall, there were 320, 4468 and 2364 deaths from hypertensive disorders, ischemic heart disease and cerebrovascular diseases, respectively. No significant associations between either mean, mean apparent, minimum or minimum apparent temperatures were found for any of the studied outcomes. Conclusions. Contrary to the European findings, we did not find inverse associations between apparent temperatures and mortality from cardiovascular or cerebrovascular causes. Factors behind the lack of association may be similar to those in urban settings in Siberia, that is, centrally heated houses and a culture of wearing large volumes of winter clothes outdoors. Further research on the sensitivity of the population in Kazakhstan to climatic factors and its adaptive capacity is warranted.

    Previous studies reported Fabry disease in 0% to 4% of young patients with cryptogenic ischemic stroke (IS). We sought to determine the prevalence of Fabry and outcomes among young Canadians with cryptogenic IS or transient ischemic attack (TIA). We prospectively enrolled individuals aged 18 to 55 with IS or speech or motor TIA, and no cause identified despite predetermined investigation. α-galactosidase-A gene was sequenced for Fabry diagnosis. National Institutes of Health Stroke Scale score was measured at presentation to quantify stroke severity. Modified Rankin Scale determined functional outcomes ≤7 days after presentation and 6 months later. We enrolled 365 patients with IS and 32 with TIA. α-galactosidase-A sequencing identified a single carrier of a genetic variant of unknown significance (p.R118C) and no well-recognized pathogenic variants. Mean National Institutes of Health Stroke Scale score was 3.1. Proportion of patients with modified Rankin Scale of 0 to 2 was 70.7% at ≤7 days and 87.4% at 6 months. National Institutes of Health Stroke Scale score at presentation and diabetes mellitus predicted 6-month modified Rankin Scale. Thirteen patients experienced 5 recurrent IS and 9 TIA during follow-up. No patient died. Most patients (98.7%) returned home. Among previous workers, 43% had residual working limitations. In this Canadian cohort of patients with cryptogenic IS or TIA, the prevalence of Fabry was 0.3% if p.R118C variant is considered as pathogenic. This suggests that more cost-effective methods should be applied for diagnosis of Fabry rather than systematic genetic screening in this population. Overall, cryptogenic IS in young adults is associated with favorable outcomes. © 2017 American Heart Association, Inc.

    Full Text Available Chronic exercise has been shown to prevent or slow age-related decline in cognitive functions in otherwise healthy, asymptomatic individuals. We sought to assess cognitive function in a stable coronary heart disease (CHD sample and its relationship to cerebral oxygenation-perfusion, cardiac hemodynamic responses, and [Formula: see text] peak compared to age-matched and young healthy control subjects. Twenty-two young healthy controls (YHC, 20 age-matched old healthy controls (OHC and 25 patients with stable CHD were recruited. Cognitive function assessment included short term-working memory, perceptual abilities, processing speed, cognitive inhibition and flexibility and long-term verbal memory. Maximal cardiopulmonary function (gas exchange analysis, cardiac hemodynamic (impedance cardiography and left frontal cerebral oxygenation-perfusion (near-infra red spectroscopy were measured during and after a maximal incremental ergocycle test. Compared to OHC and CHD, YHC had higher [Formula: see text] peak, maximal cardiac index (CI max, cerebral oxygenation-perfusion (ΔO2 Hb, ΔtHb: exercise and recovery and cognitive function (for all items (P<0.05.

  17. Epidemiology of Acquired Immune Deficiency Syndrome and Cerebrovascular Disease in a Post Antiretroviral Era.

    Kucab, Phillip; Bhattacharya, Pratik

    2017-06-01

    People with acquired immune deficiency syndrome (AIDS) develop ischemic stroke through distinct mechanisms. These include infections such as syphilis, tuberculosis, varicella, and other conditions such as cocaine abuse, endocarditis, and hypercoagulability. The effect of improved awareness, detection, and treatment with highly active antiretroviral therapy (HAART) on the incidence and outcome of AIDS patients with stroke is unknown. Data from the Nationwide Inpatient Sample from 1995 to 2010 were analyzed. Patients with ischemic stroke and AIDS were identified using ICD-9 (International Classification of Diseases) codes. Time trends for demographics, survival, and frequency of AIDS-associated conditions were analyzed. Proportion of AIDS among stroke patients increased significantly during the study. Median age of all strokes decreased from 75 years in 1995 to 72 years in 2010. Conversely, median age for men with stroke and AIDS increased from 43 years to 53 years; and for women with stroke and AIDS, from 41 years to 51 years. Death rates from stroke in the AIDS patients declined. In recent years, the death rates from stroke are similar to patients without HIV/AIDS. Stroke patients with AIDS had increased odds of syphilis (odds ratio [OR]: 33.50), varicella (OR: 48.34), tuberculosis (OR: 137.48), endocarditis (OR: 5.19), cocaine abuse (OR: 26.05), and hypercoagulability (OR: 4.82). In the HAART era, the median age of incident stroke in AIDS has increased and the mortality from stroke has improved. Research should focus on optimal management of dyslipidemia while on HAART. Whether HAART can reduce the incidence and improve survival of stroke needs to be explored. Copyright © 2017 National Stroke Association. Published by Elsevier Inc. All rights reserved.

Arterial stiffness (AS can be determined by measurement of arterial pulse wave velocity (APWV. Separate from any role as a surrogate marker, AS is an important determinant of pulse pressure, left ventricular function and coronary artery perfusion pressure. Proximal elastic arteries and peripheral muscular arteries respond differently to aging and to medication. Endogenous human growth hormone (hGH, secreted by the anterior pituitary, peaks during early adulthood, declining at 14% per decade. Levels of insulin-like growth factor-I (IGF-I are at their peak during late adolescence and decline throughout adulthood, mirror imaging GH. Arterial endothelial dysfunction, an accepted cause of increased APWV in GH deficiency (GHD is reversed by recombinant human (rh GH therapy, favorably influencing the risk for atherogenesis. APWV is a noninvasive method for measuring atherosclerotic and hypertensive vascular changes increases with age and atherosclerosis leading to increased systolic blood pressure and increased left ventricular hypertrophy. Aerobic exercise training increases arterial compliance and reduces systolic blood pressure. Whole body arterial compliance is lowered in strength-trained individuals. Homocysteine and C-reactive protein are two infl ammatory markers directly linked with arterial endothelial dysfunction. Reviews of GH in the somatopause have not been favorable and side effects of treatment have marred its use except in classical GHD. Is it possible that we should be assessing the combined effects of therapy with rhGH and rh

    Severity of acute vascular illness may have changed in the last decades due to improvements in primary and secondary prevention. Population-based data on the severity of acute ischemic cerebrovascular disease are sparse. We aimed to examine incidence, characteristics and severity of acute ischemic cerebrovascular disease in a well-defined population. All patients admitted with transient ischemic attack (TIA) or acute ischemic stroke from March 1, 2007, to February 29, 2008, with residence in the Aarhus area, were included. Incidence rates and characteristics of TIA and ischemic stroke were compared. TIA accounted for 30%, TIA and minor stroke combined for 65% of all acute ischemic cerebrovascular events. Age-adjusted incidence rates of TIA and ischemic stroke were 72.2/100,000 and 129.5/100,000 person-years, respectively. TIA patients were younger than stroke patients (66.3 vs. 72.7 years; p TIA and stroke patients share many characteristics; however, TIA patients are younger and have fewer manifestations of atherosclerotic diseases, indicating a high potential for secondary prevention.

    Full Text Available La resonancia magnética de imágenes permite investigar aspectos morfológicos y funcionales del cerebro, lo cual es sumamente útil para diagnosticar enfermedades neurológicas, incluidas las cerebrovasculares y, por supuesto, la isquemia cerebral en las primeras horas de ocurrida, de modo que facilita seguir la evolución del ictus, reducir la zona de necrosis y garantizar una mejor calidad de vida de los pacientes. A diferencia de la tomografía y la angiografía no utiliza radiaciones ionizantes. En este artículo se concluye, entre otras inferencias, que su elevada sensibilidad supera el número de confirmaciones obtenidas a través de la tomografía axial computarizada.Magnetic resonance imaging allows to investigate morphological and functional aspects of the brain, something extremely useful to diagnose neurological diseases, including the cerebrovascular diseases and, of course, the cerebral ischemia in the first hours of its ocurrence, so it facilitates to follow the clinical course of ictus, to reduce the necrosis area and to guarantee a better life quality of patients. Contrary to tomography and angiography it doesn't use ionizing radiations. In this article it is concluded, among other things, that its high sensibility overcomes the number of confirmations obtained through computarized axial tomography.

    Technetium-99m d,l-hexamethyl-propyleneamine oxime ([sup 99m]Tc-HM-PAO) cerebral SPECT and whole body scintigraphy (WBS) were performed in 5 patients without cerebro-vascular disease (CVD) (Group 1), 31 patients with CVD but not hemiparesis (Group 2) and 18 patients with CVD and hemiparesis (Group 3). Four ROIs were drawn manually around the whole body (WB), brain (Br), right and left thigh (Th). We calculated some ratios: the total counts in the brain over the total counts in the whole body (Br/WB), the total counts in the thigh over the total counts in the whole body (Th/WB) and the mean counts in the thigh over the mean counts in the brain (Th/Br).The Br/WB was 6.9[+-]1.8%, rt-Th/WB was 4.9[+-]2.1%, lt-Th/WB was 5.1[+-]1.3% and Th/Br was 0.46[+-]0.17 in group 1. Whole body scintigraphies in group 1 revealed clear and similar images between right and left thigh. The Br/WB was 6.7[+-]1.4%, Th/WB of paretic side was 4.6[+-]1.0%, Th/WB of non-paretic side was 5.8[+-]1.2% and Th/Br was 0.47[+-]0.18 in group 3. The Th/WB in non paretic side was significantly higher than that in paretic side (p<0.01). The thigh images in group 3 revealed clear differences between paretic and non-paretic thighes. In conclusion we could acquire the clear thigh images with [sup 99m]Tc-HM-PAO. It was possible that we evaluated not only cerebral perfusion but also muscle atrophy and/or perfusion in patients with CVD using [sup 99m]Tc-HM-PAO. (author).

    1987-01-01

    The simultaneous measurement of dynamic computerized tomography scanning (DCT) with an iodine-contrast enhancement material bolus injection and a simultaneous xenon CT-CBF-study was done on 15 patients (8 cases of unilateral internal carotid occlusion; 3, of unilateral middle cerebral arterial occlusion, and 4, without any major cerebral arterial occlusion or significant arterial stenosis) with ischemic cerebro-vascular diseases at the subacute and/or chronic stage. The value of the width and corrected first moment (cMT1) as well as their functional images, as acquired from DCT data, were compared to the 1-CBF value and the 1-CBF map of the xenon CT-CBF-study. A comparison of the functional images of DCT and 1-CBF showed that there was a good correlation between them in the cases without leptomeningeal anastomosis as a collateral circulation. However, a poor correlation between them was found in the cases with leptomeningeal anastomosis as a collateral circulation. The correlation of 1-CBF and 1/width with 1/cMT1 was significant (r = 0.78, p < 0.01) in the former cases, but it was not significant in the latter cases. The results of our data were thought to be due to the difference in the tracer inflow pattern between the cases without leptomeningeal anastomosis and those with it as a collateral circulation. The factor of cerebral blood volume should be considered in a more detailed study, although our cases did not include any patients with acute cerebral infarction or recanalized cases, which are thought to show various changes in the cerebral blood volume. The 1/width and 1/cMT1 values acquired from DCT well reflected the CBF in the cases without leptomeningeal anastomosis as a collateral circulation. (author)

    2006-10-01

    Full Text Available Se analiza la evidencia existente a la fecha sobre los mecanismos fisiopatológicos que pueden generar accidentes cerebrovasculares en la enfermedad de Fabry. Esta entidad es el resultado de la deficiencia de a-galactosidasa A, lo que resulta en depósito patológico de glicoesfingilípidos en distintas poblaciones celulares. Asociados a la insuficiencia renal y cardíaca, los accidentes cerebrovasculares pueden derivar en la muerte de los pacientes. Durante mucho tiempo el único mecanismo generador de daño vascular informado fue la oclusión vascular por depósito lipídico a nivel endotelial. En la actualidad se describen otros mecanismos. El advenimiento de la terapia de reemplazo enzimático ha generado gran expectativa en cuanto la posibilidad de reversión de estos mecanismos. Si bien la evidencia es escasa y son necesarios más estudios a largo plazo, algunos informes demuestran que luego de meses, el tratamiento ha logrado revertir algunos de los mecanismos implicados.The objective is to analyze the updated evidence on the physiopathological mechanisms that can generate cerebrovascular damage in Fabry disease. Fabry disease is the result of the deficiency of a-galactosidasa A, which causes pathological storage of glycosphingolipids, in different cells. Associated to renal and cardiac insufficiency, cerebrovascular complications can derive in the death of the patients. During a long time the only reported mechanism was the vascular occlusion by deposit of lipids at endothelial level. At the present time, other mechanisms are postulated. The arrival of enzyme replacement therapy has generated great expectation on the possibility of reversion of these alterations. Although the evidence is scarce and more long term studies are necessary, some reports demonstrate that after months, the treatment has managed to revert some of the mechanisms involved.

  5. Application of infrared thermal imaging in the study of preventing cardiovascular and cerebrovascular diseases with Chinese medicine health food

    2009-08-01

    To explore the assessing technique which could objectively reflect the characteristics of Chinese medicine in the prevention of cardiovascular and cerebrovascular diseases, four balance features of infrared thermal images (ITI) corresponding to the up and down, left and right, proximal and distal balance of blood circulation of human body were studied. First, the ITI features of the middle-aged and elderly people with lipid abnormality history were compared with those of the healthy youth. It was found that the balance state of the youth was significantly better than that of the middle-aged and elderly, Pfood with the function of helping to decrease serum lipid, on the balance features. The subjects were middle-aged and elderly people with lipid abnormality history. Shengyi capsule was taken by the trial group while Xuezhikang capsule (with lovastatin as the main effective component) by the control group for 108 days. The balance features of ITI showed that Shengyi was significantly better than Xuezhikang in improving the whole body balance of blood circulation (including the up and down, left and right, proximal and distal balance). The relative efficacy rate was 81.0% for the trial group and 33.3% for the control group, there was significant difference between the two groups (P=0.002). Shengyi could effectively decrease the low density lipoprotein cholesterol (LDL-C) but the effect of Xuezhikang in decreasing total cholesterol (TC) and LDL-C was better than Shengyi. Though the lipid-lowering effect of Shengyi was not as good as Xuezhikang, ITI reflected the obvious advantage of Shengyi in improving the whole body balance of blood circulation which indicated that helping to decrease serum lipid is only part of the health function of Shengyi. The physiology and pathology basis of the influences of Shengyi on the four balance features and its relationship with the clinical outcome deserves further study. So the prospect of infrared thermal imaging is indicated as

    Full Text Available BACKGROUND: Epidemiological studies have evaluated the association between nicotinamide adenine dinucleotide phosphate (NADPH oxidase p22(phox C242T polymorphism and risk of ischemic cerebrovascular disease (ICVD, but the results remain inconclusive. This meta-analysis was therefore designed to clarify these controversies. METHODOLOGY/PRINCIPAL FINDINGS: Systematic searches of electronic databases Embase, PubMed and Web of Science, as well as hand searching of the references of identified articles and the meeting abstracts were performed. Statistical analyses were performed using software Review Manager (Version 5.1.7 and Stata (Version 11.0. The pooled odds ratios (ORs with 95% confidence intervals (95%CIs were performed. Fixed or random effects model was separately used depending on the heterogeneity between studies. Publication bias was tested by Begg's funnel plot and Egger's regression test. A total of 6 studies including 1,948 cases and 2,357 controls were combined showing no statistical evidence of association between NADPH oxidase p22(phox C242T polymorphism and overall ICVD (allelic model: OR = 1.08, 95%CI = 0.93-1.26; additive model: OR = 1.33, 95%CI = 0.81-2.17; dominant model: OR = 1.00, 95%CI = 0.86-1.15; recessive model: OR = 1.06, 95%CI = 0.77-1.45. Significant association was found in large-artery atherosclerotic stroke subgroup (allelic model: OR = 1.12, 95%CI = 0.88-1.41; additive model: OR = 1.36, 95%CI = 0.60-3.09; dominant model: OR = 1.25, 95%CI = 0.74-2.11; recessive model: OR = 2.17, 95%CI = 1.11-4.23. No statistical evidence of significant association was observed for small-vessel occlusive stroke, as well as Asian subgroup and Caucasian subgroup. Statistical powers on the combined sample size (total and subgroup were all lower than 80%. CONCLUSIONS/SIGNIFICANCE: This meta-analysis indicates that NADPH oxidase p22(phox C242T polymorphism is more associated

  10. The group study of diagnostic efficacy of cerebro-vascular disease by I-123 IMP SPECT images obtained with ring type SPECT scanner

    Machida, Kikuo; Honda, Norinari; Matsumoto, Toru

    1991-01-01

    We performed two image reading experiments in order to investigate the diagnostic capability of I-123 IMP SPECT obtained by the ring type SPECT scanner in cerebro-vascular disease. Fourteen physicians diagnosed SPECT images of 55 cases with reference to clinical neurological information, first without brain XCT images and second with XCT images. Each physician detected perfusion defects and redistributions of I-123 IMP and assigned a confidence level of abnormality for these SPECT findings by means of five rating method. From results obtained by ROC analysis, we concluded as follows. (1) Generally, I-123 IMP SPECT is a stable diagnostic modality in the diagnosis of cerebro-vascular disease and the image reading of XCT had no effects on the diagnosis of SPECT on the whole of physician. (2) However, there were unnegligible differences among individuals in the detectability of findings and the effect of XCT image reading. (3) Detectability of redistribution of I-123 IMP was lower than that of perfusion defect and inter-observer variation in the diagnostic performance for redistribution was larger than that of perfusion defect. The results suggest that it is necessary to standardize diagnostic criteria among physicians for redistribution of I-123 IMP. (author)

    [Purpose] The purpose of this study was to clarify the influence of high-intensity pulse irradiation with linear polarized near-infrared rays (HI-LPNR) and stretching on hypertonia in cerebrovascular disease patients. [Subjects and Methods] The subjects were 40 cerebrovascular disease patients with hypertonia of the ankle joint plantar flexor muscle. The subjects were randomly allocated to groups undergoing treatment with HI-LPNR irradiation (HI-LPNR group), stretching (stretching group), HI-LPNR irradiation followed by stretching (combination group), and control group (10 subjects each). In all groups, the passive range of motion of ankle dorsiflexion and passive resistive joint torque of ankle dorsiflexion were measured before and after the specified intervention. [Results] The changes in passive range of motion, significant increase in the stretching and combination groups compared with that in the control group. The changes in passive resistive joint torque, significant decrease in HI-LPNR, stretching, and combination groups compared with that in the control group. [Conclusion] HI-LPNR irradiation and stretching has effect of decrease muscle tone. However, combination of HI-LPNR irradiation and stretching has no multiplier effect.

    1992-04-01

    Regional cerebral blood flow (rCBF) by {sup 123}I-IMP SPECT was measured before and 2.8, 10.3 months during medication of bifemelane hydrochloride in 10 patients with cerebrovascular diseases and compared with 5 control patients without medication. Semiquantitative rCBF indices of asymmetry and redistribution (AI, RI) were calculated from mean regional counts/pixel of each region of interest (ROI) in the early and delayed images of IMP SPECT. Before medication, no significant differences of RI and AI were observed between patients with and without medication of bifemelane hydrochloride. Significantly higher RI was observed in the second measurement 2.8 months in mean during medication of bifemelane hydrochloride, while AI was less in patients medicated with bifemelane hydrochloride. In the third measurement 10.3 months in mean during medication of bifemelane hydrochloride, RI was kept to be higher than that in the second measurement of the control patients without medication. The ratio of the number of ROI, where the redistribution being observed, was significantly higher in patients medicated than in control patients. From the results, medication of bifemelane hydrochloride might keep the redistribution phenomenon, which may indicate reversible cerebral ischemia, more persistently and intensively in patients with cerebrovascular diseases.

  13. Evaluation of surgical treatment using N-isopropyl p[123I]iodoamphetamine and ringed gamma camera single photon computed tomography in patients with cerebrovascular disease

    Oshibuchi, Masao; Sato, Mitsutaka; Muramoto, Masato; Kim, I.; Ohtake, Hisashi.

    1988-01-01

    The evaluation of surgical treatment via N-isopropyl-p-[ 123 I]iodoamphetamine( 123 I-IMP) and a ringtyped SPECT instrument on 25 patients undergoing operation for the treatment of cerebrovascular disease was analyzed using 50 test results obtained by means of 123 IMP SPECT. The difference between a ratio of count on the healthy side to that on the diseased side measured before operation and that measured after operation was found to be over 3.8 % in patients showing the improvement of clinical symptoms and below 1.6 % in patients showing no improvement. Among patients undergoing to removal of hematoma, the difference was calculated to be over 10 % when clinical symptoms were improved, and to be minus figures when no improvement was attained. The method employed in this study was confirmed to be useful because it is easy to perform in a non-invasive way, and numerically expresses the state of patients before and after operation. (author)

  14. Association Between Inflammatory Skin Disease and Cardiovascular and Cerebrovascular Co-Morbidities in US Adults: Analysis of Nationwide Inpatient Sample Data.

    Kwa, Michael C; Silverberg, Jonathan I

    2017-12-01

    Psoriasis, atopic dermatitis or eczema (AD-E), pemphigus, bullous pemphigoid (BP), and hidradenitis are chronic inflammatory skin disorders associated with systemic immune activation, considerable symptom burden, stigma, functional disturbances, and mental health symptoms. All of these might increase cardiovascular risk. The objective of this study was to determine whether these inflammatory skin diseases are associated with increased cardiovascular/cerebrovascular risk and/or disease. We analyzed data from the 2002-2012 National Inpatient Sample, including a representative 20% sample of all US hospitalizations (n = 72,108,077 adults). In multivariate logistic regression models with propensity score matching, patients hospitalized with versus without a diagnosis the inflammatory skin diseases examined had higher odds of obesity (odds ratio [95% confidence interval] for pemphigus: 1.16 [1.05-1.29]; BP 1.14 [1.06-1.23]; AD-E: 1.82 [1.79-1.86]; psoriasis: 2.36 [2.32-2.41]; hidradenitis: 2.79 [2.59-3.01]). Inflammatory skin disease was also associated with significantly higher odds of different cardiovascular risk factors, including hypertension (pemphigus: 1.39 [1.31-1.48]; BP 1.96 [1.88-2.05]; AD-E: 1.19 [1.17-1.21]; psoriasis: 1.61 [1.59-1.64]), and diabetes mellitus with complications (pemphigus: 1.34 [1.18-1.52]; BP: 2.06 [1.90-2.24]; AD-E: 1.13 [1.10-1.17]; psoriasis: 1.39 [1.35-1.44]), as well as vascular, cardiovascular, and cerebrovascular disease, including peripheral vascular disease (pemphigus: 1.14 [1.00-1.30]; BP: 1.83 [1.69-1.98]; AD-E: 1.18 [1.14-1.22]; psoriasis: 1.32 [1.28-1.35]), peripheral and visceral atherosclerosis (BP: 1.67 [1.53-1.81]; AD-E: 1.16 [1.12-1.20]; psoriasis: 1.27 [1.24-1.30]), pulmonary circulation disorders (pemphigus: 1.67 [1.39-2.01]; BP: 2.17 [1.92-2.45]; AD-E: 1.39 [1.33-1.45]; psoriasis: 1.37 [1.31-1.43]), congestive heart failure (pemphigus: 1.75 [1.60-1.90]; BP: 2.82 [2.68-2.98]; AD-E: 1.10 [1.07-1.13]; psoriasis: 1.05 [1

    Objective. The authors previously reported five transcranial Doppler ultrasonography (TCD) findings as significant in detecting clinical cerebrovascular disease in a 4-year study in patients with sickle cell disease. This is a follow-up to evaluate the validity of the original findings over another 4-year period during which the study population doubled. A clinical follow-up of the original asymptomatic sickle cell patients with positive TCD, MRA, and MRI was also made. Results. Of the 4 out of original 46 control patients in 1992 who had positive MRA and TCD, 3 have subsequently had clinical stroke. None of the 9 original patients with positive TCD and positive MRI but negative MRA have developed stroke. All five original TCD indicators of disease were still significant (P<0.05) for detecting clinical disease: maximum velocity in ophthalmic artery (OA)>35 cm/s, mean velocity in middle cerebral artery (MCA) >170 cm/s, resistive index (RI) in OA<50, velocity in OA greater than in MCA, and velocity in posterior cerebral (PCA), vertebral, or basilar arteries greater than in MCA. Four additional factors were also significant: turbulence, PCA or ACA without MCA, RI<30, and maximum velocity in MCA>200 cm/s. (orig.)

    Background/Aims The goal of this study was to examine the reliability and validity of the Changsha version of the Montreal Cognitive Assessment (MoCA-CS) in ischemic cerebrovascular disease patients of Hunan Province, China, and to explore the optimal cutoff score for detecting vascular cognitive impairment-no dementia (VCI-ND) and vascular dementia (VD). Methods Three hundred and thirty-eight ischemic cerebrovascular disease patients (131 with normal cognition, 111 with VCI-ND, and 96 with VD) and 132 healthy controls were recruited. All participants accepted examination by the MoCA-CS, Mini-Mental State Examination (MMSE), and other related scales. A detailed neuropsychological battery was used for making a final cognitive diagnosis. SPSS 16.0 statistical software was used for reliability, validity examination, and optimal cutoff score detection. Results Cronbach's α of the MoCA-CS was 0.884, and test-retest and interrater reliability of the MoCA-CS were 0.966 and 0.926, respectively. MoCA-CS scores were highly correlated with MMSE scores (r = 0.867) and simplified intelligence quotients (r = 0.822). The results indicate that 1 point should be added for subjects with less than 6 years of education, and that the optimal cutoff score for detecting VCI-ND is 26/27 (sensitivity 96.1%, specificity 75.6%), whereas the optimal cutoff score for detecting VD is 16/17 (sensitivity 92.7%, specificity 96.3%). Conclusion The MoCA-CS has good reliability and validity, and is a useful cognitive screening instrument for detecting VCI in the Chinese population. PMID:23637698

    Cardiac iodine-123 metaiodobenzylguanidine ( 123 I-MIBG) scintigraphy is an established method of assessment of cardiovascular sympathetic function. The aim of the present study was to investigate the long-term cardiovascular predictive value of cardiac 123 I-MIBG scintigraphy parameters in Japanese type 2 diabetic patients without structural heart disease. Cardiac 123 I-MIBG scintigraphy in 108 patients with type 2 diabetes who did not have structural heart disease, was evaluated. The washout rate (WR) was considered enhanced if it was ≥40%. Accurate follow-up information for 4.6 years was obtained in 54 enhanced WR patients (27 male; mean age, 61±11 years) and in 54 sex- and age-matched preserved WR patients (27 male; mean age, 61±10 years). Major adverse cardiac and cerebrovascular events (MACCE) were investigated. During follow-up, 10 enhanced WR patients developed MACCE including cardiac death, coronary revascularization, stroke, and congestive heart failure, while MACCE occurred in only 3 male patients. The Kaplan-Meier curves indicated that enhanced WR patients had higher incidence of MACCE than those with preserved WR (P 123 I-MIBG scintigraphy at baseline has long-term cardiovascular predictive value in Japanese patients with type 2 diabetes without structural heart disease.

    Visit-to-visit blood pressure variability (BPV) is a simple surrogate marker for the development of atherosclerotic diseases, cardiovascular and all-cause mortality. Nevertheless, the relative prognostic value of BPV in comparison with other established vascular assessments remain uncertain. We prospectively followed-up 656 high-risk patients with diabetes or established cardiovascular or cerebrovascular diseases for the occurrence of major adverse cardiovascular events (MACEs). Baseline brachial endothelial function, carotid intima-media thickness (IMT) and plaque burden, ankle-brachial index and arterial stiffness were determined. Visit-to-visit BPV were recorded during a mean 18 ± 9 outpatient clinic visits. After a mean 81 ± 12 month's follow-up, 123 patients (19%) developed MACEs. Patients who developed a MACE had significantly higher systolic BPV, more severe endothelial function, arterial stiffness and systemic atherosclerotic burden compared to patients who did not develop a MACE (all Parea under receiver operating characteristic curve (AUC) 0.69 ± 0.03, PAUC 0.65 ± 0.03, P<0.01). After adjustment of confounding factors, a high BPV remained a significant independent predictor of MACE (hazards ratio 1.67, 95% confidence interval 1.14-2.43, P<0.01). Compared with established surrogate markers of atherosclerosis, visit-to-visit BPV provides similar prognostic information and may represent a new and simple marker for adverse outcomes in patients with vascular diseases.

    1990-12-01

    Using the {sup 133}Xenon venous method, we have studied the regional cerebral blood flow (rCBF) in 947 patients with cerebrovascular ischemic disease. In 116 stroke or TIA patients with internal carotid artery occlusion or severe stenosis, their rCBF revealed 48.9 ml/100 g/min on average in the group of one side occlusion, 46.7 ml/100 g/min in the group of both sides occlusion. These values reduced approximately 12%, 16% and 15% of the rCBF in healthy volunteers of same age, respectively. In 28 patients with moya moya disease, their rCBF tended to be higher in younger cases and lower with advanced age. In the majority of the cases, their rCBF was age-dependent with 20{similar to}25 ml/100 g/min below the curve of age-matched rCBF of healthy volunteers. The reduction of rCBF was observed in 69 (48.3%) of 143 cases clinically diagnosed as small vessel disease, in 58 (41.4%) of 140 cases with vertebro-basilar insufficiency and in 23 (44.2%) of 52 cases with syncopal attack compared with the rCBF of healthy volunteers.

  4. Measurement of regional cerebral blood flow with the Xenon-133 inhalation procedure in patients with cerebrovascular disease

    Hartmann, A.

    1985-10-01

    Measurement of regional cerebral blood flow with inhalation of Xenon-133 and recording of regional clearance curves by stationary external detectors permits repeated estimation of bilateral cortical blood flow in resting position and after different activating procedures. Measurements can be performed on an outpatient basis, measurements in critical ill patients are possible as well. Compared to Xenon-133 single photon emission computerized tomography smaller doses can be used. Compared to Iodine-123 amphetamie SPECT actual flow calculation without arterial puncture is possible. Drawbacks of the technique are the two-dimensional imaging, unsufficient indication of the look through phenomenon and non-perfused tissue with zero-flow. However, measurement of rCBF with this technique are helpful in individual diagnosis of the following diseases: transient ischemic attacks with prolonged ischemia, communicating hydrocephalus with normal intracranial pressure, follow up studies in hemodilution, evaluation of patients with polyarterial vascular disease in respect to neurosurgical or vasculosurgical intervention, subarachnoid hemorrhage and head trauma.

    Non-communicable diseases represent one of the greatest challenges for health policymakers. The main objective of this study is to analyse the development of standardised mortality rates for cerebrovascular disease, which is one of the most common causes of deaths, in relation to income inequality in individual regions of the Slovak Republic. Direct standardisation was applied using data from the Slovak mortality database, covering the time period from 1996 to 2013. The standardised mortality rate declined by 4.23% in the Slovak Republic. However, since 1996, the rate has been higher by almost 33% in men than in women. Standardised mortality rates were lower in the northern part of the Slovak Republic than in the southern part. The regression models demonstrated an impact of the observed income-related dimensions on these rates. The income quintile ratio and Gini coefficient appeared to be the most influencing variables. The results of the analysis highlight valuable baseline information for creating new support programmes aimed at eliminating health inequalities in relation to health and social policy.

    Cardiovascular and cerebrovascular diseases (CVDs) related to overwork are common in Asia, as is death from overwork, known as karoshi. Japan was the first country in the world to introduce criteria for recognizing overwork-related CVDs in 1961. Taiwan followed Japan in putting in place new policies and then updating these in 2010. We aimed to investigate the effect of introducing the new criteria for recognizing overwork-related CVDs in both countries. We defined the baseline period as the 5 years before launch of the new criteria, then collected data to 5 years after the new criteria. We applied a Poisson regression model to analyze the longitudinal change in rates of overwork-related CVDs before and after, adjusting for indicators of working conditions. Implementation of the new criteria was associated with a 2.58-fold increase in the rate of overwork-related CVDs (p-value < 0.05). However, the examined policy framework in Taiwan still appears to miss a substantial number of cases compared to that are captured by a similar policy framework used to capture overwork-related CVD rates in Japan by a factor of 0.42 (p-value < 0.05). Accordingly, we make a case for enhancements of Taiwan's system for reporting and recognizing overwork-related diseases and deaths.

    1992-01-01

    This paper is aimed to discuss the involvement of delayed radiation effects of A-bomb exposure in cardiovascular diseases. First, the relationship between radiation and cardiovascular diseases is reviewed in the literature. Animal experiments have confirmed the relationship between ionizing radiation and vascular lesions. There are many reports which describe ischemic heart disease, cervical and cerebrovascular diseases, and peripheral disease occurring after radiation therapy. The previous A-bomb survivor cohort studies, i.e., the RERF Life Span Study and Adult Health Study, have dealt with the mortality rate from cardiovascular diseases, the prevalence or incidence of cardiovascular diseases, pathological findings, clinical observation of arteriosclerosis, ECG abnormality, blood pressure abnormality, and cardiac function. The following findings have been suggested: (1) A-bomb exposure is likely to be involved in the mortality rate and incidence of ischemic heart disease and cerebrovascular diseases; (2) similarly, the involvement of A-bomb exposure is considered in the prevalence of the arch of aorta; (3) ECG abnormality corresponding to ischemic heart disease may reflect the involvement of A-bomb exposure. To confirm the above findings, further studies are required on the basis of more accurate information and the appropriate number of cohort samples. Little evidence has been presented for the correlation between A-bomb exposure and both rheumatic heart disease and congenital heart disease. (N.K.) 88 refs

  9. Short-Term Effects of Gaseous Pollutants and Particulate Matter on Daily Hospital Admissions for Cardio-Cerebrovascular Disease in Lanzhou: Evidence from a Heavily Polluted City in China

    Full Text Available Panel studies show a consistent association between increase in the cardiovascular hospitalizations with air pollutants in economically developed regions, but little evidence in less developed inland areas. In this study, a time-series analysis was used to examine the specific effects of major air pollutants [particulate matter less than 10 microns in diameter (PM10, sulfur dioxide (SO2, and nitrogen dioxides (NO2] on daily hospital admissions for cardio-cerebrovascular diseases in Lanzhou, a heavily polluted city in China. We examined the effects of air pollutants for stratified groups by age and gender, and conducted the modifying effect of seasons on air pollutants to test the possible interaction. The significant associations were found between PM10, SO2 and NO2 and cardiac disease admissions, SO2 and NO2 were found to be associated with the cerebrovascular disease admissions. The elderly was associated more strongly with gaseous pollutants than younger. The modifying effect of seasons on air pollutants also existed. The significant effect of gaseous pollutants (SO2 and NO2 was found on daily hospital admissions even after adjustment for other pollutants except for SO2 on cardiac diseases. In a word, this study provides the evidence for the detrimental short-term health effects of urban gaseous pollutants on cardio-cerebrovascular diseases in Lanzhou.

  10. Does blood pressure lowering treatment prevents dementia or cognitive decline in patients with cardiovascular and cerebrovascular disease?

    Feigin, Valery; Ratnasabapathy, Yogini; Anderson, Craig

    2005-03-15

    There is increasing evidence that both hypertension and stroke play important roles in the development of cognitive decline and dementia. Despite five high-quality randomised controlled trials (RCTs) in this area to date, there remains uncertainty about the role of blood pressure lowering therapy in the prevention of cognitive decline and dementia. It appears that lack of definitive results from these trials can be explained on the basis of (a) insufficient power to detect modest treatment effects; (b) measurement error in the diagnosis of dementia; (c) variations in the treatment effects between different types of antihypertensive agents; and (d) bias due to missing data, variation in baseline factors such as levels of blood pressure, and the inclusion of patients with cognitive impairment at entry. Preliminary meta-analysis of RCTs supports the hypothesis that blood pressure lowering may prevent dementia in high-risk patients, that is those with vascular disease. However, a meta-analysis of individual patient data (IPD) from these, and other relevant trials in patients with vascular disease, would provide much more reliable data. If the hypothesis were confirmed, it would certainly be of considerable importance not only in terms of our understanding of the aetiology of dementia, but also in promoting blood pressure lowering strategies for broader public health good.

  11. Altered low frequency oscillations of cortical vessels in patients with cerebrovascular occlusive disease – a NIRS study

    2013-12-01

    Full Text Available Analysis of cerebral autoregulation by measuring spontaneous oscillations in the low frequency spectrum of cerebral cortical vessels might be a useful tool for assessing risk and investigating different treatment strategies in carotid artery disease (CAD and stroke. Near infrared spectroscopy (NIRS is a non-invasive optical method to investigate regional changes in oxygenated (oxyHb and deoxygenated hemoglobin (deoxyHb in the outermost layers of the cerebral cortex. In the present study we examined oxyHb low frequency oscillations (LFOs, believed to reflect cortical cerebral autoregulation, in 16 patients with both symptomatic carotid occlusive disease and cerebral hypoperfusion in comparison to healthy controls. Each hemisphere was examined with 2 NIRS channels using a 3 cm source detector distance. Arterial blood pressure (ABP was measured via a finger plethysmograph. Using transfer function analysis ABP-oxyHb phase shift and gain as well as inter-hemispheric phase shift and amplitude ratio were assessed. We found that inter-hemispheric amplitude ratio was significantly altered in hypoperfusion patients compared to healthy controls (P= 0.010, because of relatively lower amplitude on the hypoperfusion side. The inter-hemispheric phase shift showed a trend (P = 0.061 towards increased phase shift in hypoperfusion patients compared to controls. We found no statistical difference between hemispheres in hypoperfusion patients for phase shift or gain values. There were no differences between the hypoperfusion side and controls for phase shift or gain values. These preliminary results suggest an impairment of autoregulation in hypoperfusion patients at the cortical level using NIRS.

    The A-S-C-O classification may be better than other methods for classifying ischaemic stroke by aetiology. Our aims are to describe A-S-C-O phenotype distribution (A: atherosclerosis, S: small vessel disease, C: cardiac source, O: other causes; 1: potential cause, 2: causality uncertain, 3: unlikely to be a direct cause although disease is present) and compare them to the Spanish Society of Neurology's Cerebrovascular Disease Study Group (GEECV/SEN) classification. We will also find the degree of concordance between these classification methods and determine whether using the A-S-C-O classification delivers a smaller percentage of strokes of undetermined cause. We analysed those patients with ischaemic stroke admitted to our stroke unit in 2010 with strokes that were classified according to GEECV/SEN and A-S-C-O criteria. The study included 496 patients. The percentages of strokes caused by atherosclerosis and small vessel disease according to GEECV/SEN criteria were higher than the percentages for potential atherosclerotic stroke (A1) (14.1 vs. 11.9%; P=.16) and potential small vessel stroke (S1) (14.3 vs. 3%; Pcause of stroke and other potential causes (O1) were observed. Some degree of atherosclerosis was present in 53.5% of patients (A1, A2, or A3); 65.5% showed markers of small vessel disease (S1, S2, or S3), and 74.9% showed signs of cardioembolism (C1, C2, or C3). Fewer patients in the group without scores of 1 or 2 for any of the A-S-C-O phenotypes were identified as having a stroke of undetermined cause (46.6 vs. 29.2%; P0.8 (unusual causes and O1). Our results show that GEECV/SEN and A-S-C-O classifications are neither fully comparable nor consistent. Using the A-S-C-O classification provided additional information on co-morbidities and delivered a smaller percentage of strokes classified as having an undetermined cause.

    Extracranial superficial temporal artery (STA) calcification is an unusual finding seen in patients with chronic kidney disease and has unknown ramifications with respect to intracranial ischemic disease. We sought to determine the association between the risk factors for vascular calcification and this rare phenomenon, in patients with chronic renal failure, and to assess the coexistence of cerebral ischemia. Medical records and laboratory data on risk factors for vascular calcification were retrospectively retrieved for 453 patients with a discharge diagnosis of end-stage renal disease (ESRD). CT head examinations were reviewed to identify and associate STA calcification with 1) risk factors for the vascular calcification, 2) intracranial artery calcification, and 3) cerebral ischemia (white matter and/or cortical ischemic changes). STA calcification was present in 9.9% (45/453) of the studied cohort. The prevalence of cerebral ischemia was 24.4% (11/45) in patients with STA calcification and 9.3% (38/408) in patients without it. Diabetes mellitus (OR: 2.56, 95% CI: 1.059-6.208; P=0.037) was independently associated with the risk of STA calcification. The risk of cerebral ischemia, however, was not related to STA calcification (P=0.221). The presence of diabetes mellitus is important in describing the risk of STA calcification in patients with ESRD, whereas age, gender, hypertension, serum calcium, serum phosphate, or serum hemoglobin levels are not. The risk of cerebral ischemia is not related to STA calcification but has the strongest association with diabetes mellitus

    In Japan, overwork-related disorders occur among local public employees as well as those in private businesses. However, to date, there are no studies reporting the state of compensation for cerebrovascular/cardiovascular diseases (CCVD) and mental disorders due to overwork or work-related stress among local public employees in Japan over multiple years. This report examined the recent trend of overwork-related CCVD and mental disorders, including the incidence rates of these disorders, among local public employees in Japan from the perspective of compensation for public accidents, using data from the Japanese Government and relevant organizations. Since 2000, compared to CCVD, there has been an overall increase in the number of claims and cases of compensation for mental disorders. Over half of the individuals receiving compensation for mental disorders were either in their 30s or younger. About 47% of cases of mental disorders were compensated due to work-related factors other than long working hours. The incidence rate by job type was highest among "police officials" and "fire department officials" for compensated CCVD and mental disorders cases, respectively. Changes in the trend of overwork-related disorders among local public employees in Japan under a legal foundation should be closely monitored.

    Single photon emission computed tomography (SPECT) with xenon-133 inhalation method was undertaken within 48 hr after the onset in 68 patients with ischemic cerebrovascular disease. The results for regional cerebral blood flow (rCBF) were compared with concurrently available computed tomography (CT) scans. In patients with cerebral infarction, SPECT detected ischemic lesions earlier than CT, with the detectability being 92 %. The area with a decreased blood flow, as seen on SPECT, was more extensive than the low density area on CT, with a concomitant decrease in blood flow in the contralateral cerebral hemisphere. Crossed cerebellar diaschisis was associated with stenosis of the internal carotid artery in 50 % (7/14), and with stenosis of the middle cerebral artery in 35 % (9/26). Abnormal SPECT findings were seen in 47 % (8/17) of the patients with transient ischemic attack (TIA). Five TIA patients had a decreased rCBF on SPECT, which was not provided by CT scans. On the contrary, small infarct lesions in the cerebral basal ganglia, as observed in 4 patients, was not detected by SPECT, but detected by CT. This may imply the limitations of SPECT in the detection of deep-seated lesions of the cerebrum. The results led to the conclusion that SPECT can be performed safely even in acute, seriously ill patients to know changes in rCBF because it is noninvasive and is capable of being repeated in a short time.

    Obstructive sleep apnea (OSA) is associated with bad cardiovascular outcomes and a high prevalence of anxiety and depression. This study investigated the effects of continuous positive airway pressure (CPAP) on the severity of anxiety and depression in OSA patients with or without coronary artery disease (CAD) and on the rate of cardio- and cerebro-vascular events in those with OSA and CAD. This prospective study included patients with moderate-to-severe OSA, with or without a recent diagnosis of CAD; all were started on CPAP therapy. Patients completed the Chinese versions of the Beck Anxiety Inventory (BAI) and Beck Depression Inventory-II (BDI-II) at baseline and after 6-month follow-up. The occurrence of major adverse cardiac and cerebrovascular events (MACCE) was assessed every 3 months up to 1 year. BAI scores decreased from 8.5 ± 8.4 at baseline to 5.4 ± 6.9 at 6 months in CPAP-compliant OSA patients without CAD ( P < 0.05). BAI scores also decreased from 20.7 ± 14.9 to 16.1 ± 14.5 in CPAP-compliant OSA patients with CAD. BDI-II scores decreased in CPAP-compliant OSA patients without CAD (from 11.1 ± 10.7 at baseline to 6.6 ± 9.5 at 6 months) and in CPAP-compliant OSA patients with CAD (from 20.4 ± 14.3 to 15.9 ± 7.3). In addition, there was a large effect size (ES) of BAI and BDI in 6-month CPAP treatment of OSA patients with CAD and a large ES in those with OSA under CPAP treatment. In OSA patients with CAD, the occurrence of MACCE was significantly lower in CPAP-compliant patients than that in CPAP noncompliant patients (11% in CPAP compliant and 50% in noncompliant; P < 0.05). CPAP improved anxiety and depression in OSA patients regardless of CAD. In OSA patients with CAD, CPAP-compliant patients had a lower 1-year rate of MACCE than CPAP-noncompliant patients.

    Full Text Available The purpose of this study was to measure cerebrovascular reactivity (CVR in chronic steno-occlusive disease using a novel approach that couples BOLD imaging with acetazolamide (ACZ vasoreactivity (aczBOLD, to evaluate dynamic effects of ACZ on BOLD and to establish the relationship between aczBOLD and dynamic susceptibility contrast (DSC perfusion MRI. Eighteen patients with unilateral chronic steno-occlusive disease of the anterior circulation underwent a 20-min aczBOLD imaging protocol, with ACZ infusion starting at 5 min of scan initiation. AczBOLD reactivity was calculated on a voxel-by-voxel basis to generate CVR maps for subsequent quantitative analyses. Reduced CVR was observed in the diseased vs. the normal hemisphere both by qualitative and quantitative assessment (gray matter (GM: 4.13% ± 1.16% vs. 4.90% ± 0.98%, P = 0.002; white matter (WM: 2.83% ± 1.23% vs. 3.50% ± 0.94%, P = 0.005. In all cases BOLD signal began increasing immediately following ACZ infusion, approaching a plateau at ~8.5 min after infusion, with the tissue volume of reduced augmentation increasing progressively with time, peaking at 2.60 min (time range above 95% of the maximum value: 0–4.43 min for the GM and 1.80 min (time range above 95% of the maximum value: 1.40–3.53 min for the WM. In the diseased hemisphere, aczBOLD CVR significantly correlated with baseline DSC time-to-maximum of the residue function (Tmax (P = 0.008 for the WM and normalized cerebral blood flow (P = 0.003 for the GM, and P = 0.001 for the WM. AczBOLD provides a novel, safe, easily implementable approach to CVR measurement in the routine clinical environments. Further studies can establish quantitative thresholds from aczBOLD towards identification of patients at heightened risk of recurrent ischemia and cognitive decline.

    The study objective was to describe radiation-induced vascular abnormalities, stroke prevalence, and stroke risk factors in survivors of childhood craniopharyngioma. Twenty survivors of childhood craniopharyngioma who received radiotherapy (RT) were included in the study. A clinical history, quality of life assessment, cognitive functioning assessment, magnetic resonance angiogram or computed tomography angiogram, fasting lipid profile, and fasting glucose or hemoglobin A1c test were obtained. Median age at diagnosis was 10.3 years and median age at time of study was 29.0 years. Vascular abnormalities were detected in six (32%) of 19 patients' angiograms (vascular stenosis, decreased artery size, aneurysm, cavernoma, and small vessel disease). Five (25%) of 20 patients experienced a stroke after RT. Median time since RT was 27.8 versus 9.1 years in patients with versus without vascular abnormalities (P = 0.02). A low level of high-density lipoproteiin (HDL) was present in 100% (5/5) of patients who had a post-RT stroke as compared with 13% (2/15) of patients who did not have any post-RT stroke (P = 0.02). Previous stroke had occurred in 0% (0/5) of patients receiving growth hormone (GH) replacement at the time of study, compared to 40% (6/15) of patients who were not receiving GH replacement (P = 0.09). Patients with craniopharyngioma treated with RT have a high prevalence of stroke and vascular abnormalities, particularly those with low HDL and longer duration of time since RT. There is a trend to suggest that continual GH replacement may reduce the risk of stroke. These patients should undergo careful monitoring and aggressive modification of stroke risk factors. © 2016 Wiley Periodicals, Inc.

    A prospective study of 58 patients with sickle cell disease (SCD) by transcranial Doppler sonography (TCD) included both MRI and MRA in patients over 7 years of age and those with abnormal TCD. Arteriography was performed in cases where a stenosis was suspected on TCD. Middle cerebral artery (MCA) and basilar artery (BA) velocities were significantly higher in the sickle cell hemoglobin SS group than in the hemoglobin SC group. Patients with a MCA mean velocity of over 1.90 m/s had stenoses found by arteriography. Patients with unilaterally undetectable MCA flow had experienced a stroke and MCA thrombosis was confirmed at MRA and arteriography. We concluded that TCD is valuable in detecting arterial stenosis in SCD and will lead to consideration of these patients for intensive therapy, such as bone marrow transplantation (BMT) or transfusion regimes.

    This study aimed to evaluate the prevalence of cognitive impairment and the distribution of its risk factors among residents aged ≥60 years without cardiovascular and cerebrovascular diseases in rural areas of northern China screened with the Chinese version of the Mini-Mental State Examination (MMSE). Between 2012 and 2013, a questionnaire survey was conducted to collect basic information from participants. Cognitive function was assessed using the MMSE. In the univariate analysis, risk factors for cognitive disorders were female sex, low education and central obesity, while drinking was found to be a protective factor. In the multivariate analysis, risk factors were old age (odds ratio [OR], 1.888; 95% confidence interval [CI]: 1.256-2.838; P = 0.002 for the 70-year-old group compared with the 60-year-old group; OR, 3.593; 95% CI, 2.468-5.230; P < 0.001 for the ≥75-year-old group compared with the 60-year-old group), low education (OR, 3.779; 95% CI: 2.218-6.440; P < 0.001 for the illiterate group compared with the group with ≥9 years of education; OR, 1.667; 95% CI, 1.001-2.775; P = 0.05 for the group with less than primary school compared with the group with ≥9 years of education), and higher blood pressure (BP; OR, 1.655; 95% CI: 1.076-2.544; P = 0.002 for individuals with stage III hypertension compared with those with normal BP). These findings suggest that it is crucial to manage and control level of BP, and improve educational attainment in order to reduce the prevalence and burden of cognitive impairment among low-income residents in rural China.

    The purpose of this study was to validate a double-injection (DI) method with N-isopropyl-[{sup 123}I]p-iodoamphetamine (IMP) to measure regional cerebral blood flow (rCBF) twice in a single session of dynamic SPECT and to elucidate a possible role of this method to identify patients with occlusive disease of major cerebral arteries, who might benefit from cerebral revascularization procedures (CR). Fourteen patients with occlusion or severe stenosis of the internal carotid or middle cerebral artery were studied before and after CR to assess hemodynamic changes after revascularization treatment. We quantitatively measured rCBF before and after acetazolamide (ACZ) challenge along with cerebrovascular reserve capacity (CVR) with two injections of IMP in a single session of dynamic SPECT scans (DI method). The reliability and reproducibility of the DI method were validated by means of a simulation study and in eight patients who were examined without ACZ challenge to measure baseline rCBF twice. The analysis of simulated noisy data with realistic noise levels showed that the errors of the estimates for the first and the second rCBF and for the increase in rCBF were 2.6%, 8.1% and 10.4%, respectively. In the 8 patients examined by the DI method to measure baseline rCBF twice, the mean and the SD of percentage differences between the two consecutive measurements in rCBF were -1.3% and 5.5%, respectively. Eight out of 14 patients with occlusive disease had at least one region with a CVR less than 10%. They showed a significant increase in resting rCBF after CR, not only in the ipsilateral hemisphere (from 26.1{+-}6.4 to 33.4{+-}4.7) but also in the contralateral one (from 28.3{+-}7.0 to 34.7{+-}4.7) with a recovery of the ipsilateral CVR from 9.3{+-}17.2 to 41.2{+-}20.1%. The remaining six patients with good-moderate CVR did not show an increase in rCBF after CR (from 28.0{+-}2.7 to 28.3{+-}3.4). The three of them with a moderate CVR (10-25%) before CR showed

    Full Text Available Objective: To explore the effect of butylphthalide soft capsule on the serum hs-CRP, MMP-9, and TNF-α in patients with ischemic cerebrovascular disease in order to evaluate the the therapeutic effect in the treatment of carotid atherosclerosis. Methods: According to the carotid ultrasound results, the patients were divided into the stable plaque group (control group and the vulnerable plaque group. The patients in the vulnerable plaque group were randomized into the intervention 1 group and intervention 2 group. The patients in the two subgroups were given bayaspirin and atorvastatin. On this basis, the patients in the intervention 1 group were given butylphthalide soft capsules. The serum hs-CRP, MMP-9, and TNF-α before treatment and 6 months after treatment in each group were detected. The color Doppler ultrasound was used to measure and evaluate IMT, Crouse score, and plaque echo change. Results: The serum hs-CRP, MMP-9, and TNF-α levels before treatment between the two subgroups were significantly higher than those in the control group, but the comparison between intervention 1 group and intervention 2 group was not statistically significant. The serum hs-CRP, MMP-9, and TNF-α levels 6 months after treatment in the two subgroups were significantly reduced when compared with before treatment. The serum hs-CRP, MMP-9, and TNF-α levels after treatment in the intervention 1 group were significantly lower than those in the intervention 2 group. IMT 6 months after treatment in the two subgroups was significantly reduced when compared with before treatment. The reduced degree of IMT after treatment in the intervention 1 group was significantly greater than that in the intervention 2 group. Crouse score after treatment in the two subgroups was significantly reduced when compared with before treatment, but the comparison between the two groups was not statistically significant.

In this study, the first wave (2,812 elders from the New Haven Epidemiological Study of the Elderly (EPESE was used. These population-weighted data combined a stratified, systematic, clustered random sample from independent residences and a census of senior housing. Physical conditions included progressive cerebrovascular disease (CVD; hypertension, silent CVD, stroke, and vascular cognitive impairment [VCI] and co-occurring excess weight and/or diabetes. These conditions and interactions (clusters simultaneously predicted 20 depression items and a latent trait of depression in participants with subsyndromal (including subthreshold depression (11≤ Center for Epidemiologic Studies Depression Scale [CES-D] score ≤27. The option for maximum likelihood estimation with standard errors that are robust to non-normality and non-independence in complex random samples (MLR in Mplus and an innovation created by the author were used for estimating unbiased effects from latent trait models with exhaustive specification.

    To study the association of air pollution with health service demand of the elderly and middle-age patients with cardiovascular and cerebrovascular diseases, and to provide a scientific basis for development of environmental protection policy and health service policy of the Chinese government. This study included survey data on self-evaluated health, outpatient service demand and inpatient service demand of the patients with hypertension, heart disease and stroke in 62 cities of 17 provinces from China Health and Retirement Longitudinal Study (CHARLS) in 2011 and 2013, and combined it with the data on the annual concentrations of inhalable particulate matter (PM(10)), sulfur dioxide(SO(2)) and nitrogen dioxide (NO(2)) of those provinces and cities. Conditional Logistic regression was carried out to assess the possible effects of air pollutants on self-evaluated health and health service utilization. The results showed that turning points existed in the effects of concentrations of NO(2) and SO(2) on the health service demand of the patients with hypertension, heart disease and stroke. The inpatient service demand of the hypertension patients increased with NO(2) concentration when it was lower than 35.1 μg/m(3) and decreased with NO(2) concentration for higher value. Self-evaluated health of the patients with heart disease and stroke decreased with SO(2) concentration when it was lower than 63.8 μg/m(3) and increased with SO(2) concentration for higher value. In addition, no evidence was found for the association between PM(10) and health service demand. Air pollution may have effects on health service demand of the patients with hypertension,cardiovascular and cerebrovascular diseases, and different air pollutants at high or low concentration may have different health effects.

    Patients with chronic kidney disease (CKD) have an increased risk of adverse cardio-cerebrovascular events. We examined whether stress myocardial perfusion single photon emission computed tomography (SPECT) provides reliable prognostic markers for these patients. In this multicenter, prospective cohort trial from the Gunma-CKD SPECT study protocol, patients with CKD [estimated glomerular filtration rate (eGFR) < 60 min/ml per 1.73 m{sup 2}] undergoing stress {sup 99m}Tc-tetrofosmin SPECT for suspected or possible ischemic heart disease were initially followed for 1 year, with the following study endpoints: primary, the occurrence of cardiac deaths (CDs), and secondary, major adverse cardiac, cerebrovascular, and renal events (MACCREs). The summed stress score (SSS), summed rest score, and summed difference score (SDS) were estimated with the standard 17-segment, 5-point scoring model. Left ventricular end-diastolic volume, end-systolic volume (ESV), and ejection fraction were measured using electrocardiogram-gated SPECT. During the first year of follow-up, 69 of 299 patients experienced MACCREs (CD, n = 7; non-fatal myocardial infarction, n = 3; hospitalization for heart failure, n = 13; cerebrovascular accident, n = 1; need for revascularization, n = 38; and renal failure, i.e., hemodialysis initiation, n = 7). ESV and SSS were associated with CDs (p < 0.05), and eGFR and SDS were associated with MACCREs (p < 0.05), in multivariate logistic analysis. Patients with high ESV and high SSS had a significantly higher CD rate during the first year than the other CKD patient subgroups (p < 0.05). Patients with low eGFR and high SDS had a significantly higher MACCRE rate than the other subgroups (p < 0.05). Myocardial perfusion SPECT can provide reliable prognostic markers for patients with CKD. (orig.)

    Studies of computed tomography were performed in 367 patients diagnosed as dementia clinically. The mean age was 70.1 years. By the clinicians 240 were classified as senile dementia of Alzheimer's type, 79 as multiinfarct dementia, and 48 were not determined definitely. In 3%, the CT studies did detect treatable causes like tumors, subdural hematomas and communicating hydrocephalus. In about 57% was found by CT a diffuse brain atrophy without focal tissue changes as to expect if occurring a cerebrovascular disease. In 25% there were focal changes of the brain tissue in CT to define as residuals of infarctions in addition to the signs of cerebral atrophy. The results of the CT studies were normal in 15% despite of the evidence of dementia clinically. The analysis of the material did show that a cerebrovascular disease as a cause of dementia is suspected clinically in much more cases than CT studies are able to prove focal pathological changes of the brain tissue due to disorders of cerebral blood flow really.

    It was aimed to study the relationships between addiction behaviors and human health and well-being in East Asians in a national and population-based setting. Data were retrieved from Japanese General Social Survey, 2010. Information on demographics, lifestyle factors, addiction behaviors and self-reported health conditions and well-being in Japanese adults was obtained by household interview. Analysis included chi-square test, logistic and multi-nominal regression modeling. Of 5003 Japanese adults (aged 20-89) included in the study cohort, 13.8%, 14.7%, 4.8% and 5.5% were addicted to drinking, smoking, gambling and video games, respectively while 10.6%, 13.8%, 4.3% and 11.4% were exposed to co-residing family member's drinking, smoking, gambling and video game addiction behaviors, respectively. People who reported addiction to drinking had poor self-rated health, hypertension and food allergy. People who reported addiction to smoking had fair to poor self-rated health, unhappiness, cerebrovascular disease and itchy skin. People who reported addiction to gambling had fair to poor self-rated health and unhappiness. People who reported addiction to video games had poor self-rated health and heart disease. People who were exposed to addiction to drinking, smoking, gambling and video games from co-residing family member(s) also reported hay fever, poor self-rated health and unhappiness. Self and environmental exposures to drinking, smoking, gambling or video game addiction are associated with adult hypertension, heart and cerebrovascular diseases, allergy, self-rated health and happiness. Future public health programs continuing to minimize self and environmental exposures to addiction behaviors tackling health concerns would still be encouraged. Copyright © 2014 Elsevier Ireland Ltd.

    Adverse effects of intravenous acetazolamide administration for evaluation of cerebrovascular reactivity using brain perfusion single-photon emission computed tomography (SPECT) were prospectively investigated in 100 patients with major cerebral artery, atherosclerotic, and steno-occlusive diseases. All patients underwent two SPECT studies (with and without acetazolamide challenge) at an interval of 2 or 3 days, received a questionnaire immediately after each SPECT study, and returned the answered questionnaire within 7 days after the study. None of the 100 patients studied experienced any symptoms during the SPECT study without acetazolamide challenge. Sixty-three patients (63%) developed symptoms during the SPECT study with acetazolamide challenge, such as headache, nausea, dizziness, tinnitus, numbness of the extremities, motor weakness of the extremities, and general malaise 1-3 hours (mean 1.6 hours) after administration of acetazolamide, and these symptoms lasted for 0.5-72 hours (mean 7.9 hours). Multivariate statistical analysis revealed that younger age (95% confidence interval [CI] 0.896-0.980, p=0.0047) and female sex (95% CI 1.178-16.129, p=0.0274) were significantly associated with development of symptoms with acetazolamide challenge. The incidences of the development of symptoms with acetazolamide challenge were 91% (21/23) and 41% (12/29) in subgroups of women <70 years and men ≥70 years, respectively. Patients should be informed of such adverse effects of intravenous acetazolamide administration prior to the acetazolamide challenge test for evaluation of cerebrovascular reactivity. (author)

    Today, the diagnostic and therapeutic principles in the management of stroke are changing. Prevention of stroke is one of the major fields of research. One important aim of the newly developed diagnostic techniques is the identification of a particular subgroup of patients with compromised cerebral circulation who will benefit from surgical or medical therapies. The assessment of the CVRC with tracer techniques and the acetazolamide test seem to be a realiable and promising method for this purpose: 1. In carotid artery occlusion, the measurement of CVRV facilitates the identification of a subgroup of patients with compromised CVRC who show an improvement of CVRC after EC-IC bypass surgery. The value of bypass surgery for the prevention of stroke however, has to be confirmed by prospective studies. 2. The benefit from carotid surgery for patients with high-grade carotid stenosis and transient ischemic attack has been convincingly demonstrated by several studies. In asymptomatic patients, however, desobliteration of the carotid artery remains controversial. The identification of asymptomatic cases with compromised CVRC probably contributes to the recognition of patients with a high risk of suffering hemodynamic stroke. 3. In vascular dementia, cerebral blood flow measurements at rest alone have not been useful. CVRC measurements may offer a diagnostic advance in this still not well understood disease. (orig.)

    Regional cerebral blood flow (CBF) was compared on CBF-SPECT brain images using two perfusion imaging agents, N-isopropyl-p-[ 123 I]iodoamphetamine ( 123 I-IMP) and 99m Tc-hexamethylpropyleneamine oxime ( 99m Tc-HMPAO), in the same patients with ischemic cerebrovascular disease. The subjects were 8 healthy volunteers (group A) and 16 patients with chronic cerebral infarction (group B). SPECT data were normalized to the count density of the tracer in the whole brain, and then converted to the absolute units of CBF by multiplying average 113 Xe-CBF in the whole brain. One-way analysis of variance (ANOVA), grouped by right and left hemispheres in group A and the affected and contralateral hemispheres in group B, was used to assess changes in regional CBF patterns in the two groups. CBF in all regions was significantly reduced on SPECT images, irrespective of the tracers, in group B. F value was higher on IMP images than HMPAO images for the frontal, temporal and occipital cortices, thalamus, and striatum); on the contrary, it was higher on HMPAO images than IMP images for the central lobule, parietal cortex, hippocampus, and centrum semiovale. Two-way ANOVA, grouped by the affected hemisphere in group B, tracer, and affected hemisphere x tracer, indicated that effects of tracer and affected hemisphere x tracer for regional CBF were not significant. For cortical infarction (n=8), regional CBF values in the infarct core were 14.8±4.1 ml/100 g/min on IMP images and 17.6±3.8 ml/100 g/min on HMPAO images; the corresponding figures for the contralateral region were 34.7±8.6 ml/100 g/min and 32.6±8.4 ml/100 g/min. Image contrast was better on IMP images than HMPAO images. In conclusion, an intrasubject comparison in ischemic cerebrovascular disease showed that the detectability of HMPAO CBF-SPECT for CBF abnormalities is roughly equivalent to that of IMP-CBF-SPECT.

    In this study, we aimed to evaluate the effects of the development of aspiration pneumonia (AP) on the intensive care unit (ICU) requirements and in-hospital mortality of patients hospitalised in the neurology ward due to an acute cerebrovascular accident (CVA). Five hundred and three patients hospitalised in the neurology ward following an acute CVA were retrospectively analysed. The patients were divided into two groups: those with AP (group 1) and those without AP (group 2). Demographic characteristics and physical and radiological findings, including the localisation, lateralisation and aetiology of the infarction, in addition to ICU requirements and mortality, were evaluated. Aspiration pneumonia was detected in 80 (15.9%) patients during the in-hospital stay. Transfer to the ICU for any reason was required in 37.5% of the patients in group 1 and 4.7% of those in group 2 ( p < 0.001). In-hospital mortality occurred in 7.5% and 1.4% of the patients in group 1 and group 2, respectively ( p = 0.006). The incidence of AP was highest in patients with an infarction of the medial cerebral artery (MCA) ( p < 0.001). The AP was associated with older age ( p < 0.001), hypertension ( p = 0.007), echocardiography findings ( p = 0.032) and the modified Rankin Scale (mRS) score ( p < 0.001). Our findings suggest that the requirement rate for transfer to the ICU and the mortality rate appear to be significantly higher in patients with a diagnosis of AP. Precautions should be taken, starting from the first day of hospitalisation, to decrease the incidence of AP in patients with acute CVA, focusing especially on older patients and those with a severe mRS score.

  1. Controlled study on the effect of pentoxifylline and an ergot alkaloid derivative on regional cerebral blood flow in patients with chronic cerebrovascular disease

    Hartmann, A.; Tsuda, Y.

    1988-05-01

    Regional cerebral blood flow (rCBF) in 90 patients with CBF decreased due to vascular diseases was studied by using the xenon 133 inhalation technique and a 32-detector setup. Whereas 30 patients received their standard basic therapy only and were regarded as controls, 30 others received 3 x 2 mg/day of an ergot alkaloid (co-dergocrine mesylate), and 30 others received 3 x 400 mg pentoxifylline (slow-release formulation)/day orally. Therapy was performed for eight weeks and CBF measured before start of treatment, after a four-week treatment period, and at the end of the study. CBF did not change significantly in the control group; both the pentoxifylline and the ergot alkaloid group presented with a significant increase in the CBF. This positive effect was significantly more pronounced in the pentoxifylline group and affected more ischemic than other brain tissues. In addition, symptoms like sleep disturbances, vertigo, and tinnitus improved significantly during the pentoxifylline observation period.

    1996-01-01

    Recently, the usefulness of three-dimensional CT angiography (3D-CTA) using helical CT has been reported. Although 3D-CTA has been applied for neurosurgical diseases, especially for surgical planning, it has not done for emergency patients because of the long time required for image reconstruction and location of a helical CT scanner. We studied emergency patients with SAH, and compared the 3D-CTA with angiography and surgical findings, using TOSHIBA X vigor. Twenty-two patients with SAH were evaluated. The helical CT was performed for 55 seconds with a bolus injection of 90 ml non-ionic, iodinated contrast medium at a rate of 3 ml/sec with a delay of 20 sec. Angiography was carried out immediately after the helical CT. Eighteen of 22 cases were operated on urgently. We were able to create the 3D-CTA in about 7 minutes, and diagnose aneurysms by the 3D-CTA before angiography. The 3D-CTA was able to demonstrate 30 of 31 aneurysms including 9 unruptured aneurysms. An unruptured internal carotid-posterior communicating artery aneurysm 1.3 mm in diameter and associated with a ruptured aneurysm was not detected by either the 3D-CTA or angiography. On the other hand, an unruptured Acom aneurysm 0.8 mm in diameter and associated with a ruptured aneurysm could be detected by the: 3D-CTA, but not by angiography. The 3D-CTA gave us useful information concerning the anatomical relationship of the aneurysm, its neck and parent artery, and the surrounding branches. There were no complications or side effects associated with the helical CT scan. Although the 3D-CTA requires further development of visualization of small arteries less than 1 mm in diameter, such as perforating arteries, subtraction technique of bony structure, and a method for checking cervical arteries, it is useful for diagnosis of emergency patients with SAH and urgent operations. We believe that an operation might be performed by only the 3D-CTA without the angiography in the near future. (author)

    2005-01-01

    Purpose: To evaluate the risk of coronary heart disease (CHD) and cerebrovascular disease after radiotherapy (RT) for peptic ulcer disease. Methods and materials: Peptic ulcer disease patients treated with RT (n = 1859) or by other means (n = 1860) at the University of Chicago Medical Center between 1936 and 1965, were followed through 1997. The observed numbers of cause-specific deaths were compared with the expected numbers from the general population rates. During RT, 5% of the heart was in the treatment field and the remainder of the heart mostly received scattered radiation. A volume-weighted cardiac dose was computed to describe the average tissue dose to the entire organ. We used Cox proportional hazards regression analysis to analyze the CHD and cerebrovascular disease risk associated with RT, adjusting for confounding factors. Results: Greater than expected CHD mortality was observed among the irradiated patients. The irradiated patients received volume-weighted cardiac doses ranging from 1.6 to 3.9 Gy and the portion of the heart directly in the field received doses of 7.6-18.4 Gy. The CHD risk increased with the cardiac dose (p trend = 0.01). The cerebrovascular disease risk was not associated with the surrogate carotid dose. Conclusion: The excess CHD risk in patients undergoing RT for peptic ulcer disease decades previously indicates the need for long-term follow-up for cardiovascular disease after chest RT

    Cognition and education influence functional trajectories, but whether associations differ with subclinical brain infarcts (SBI) or white matter hyperintensity volume (WMHV) is unknown. We hypothesized that SBI and WMHV moderated relationships between cognitive performance and education and functional trajectories. A total of 1290 stroke-free individuals underwent brain magnetic resonance imaging and were followed for 7.3 years (mean) with annual functional assessments with the Barthel index (range, 0-100). Magnetic resonance imaging measurements included pathology-informed SBI (PI-SBI) and WMHV (% total cranial volume). Generalized estimating equation models tested associations between magnetic resonance imaging variables and baseline Barthel index and change in Barthel index, adjusting for demographic, vascular, cognitive, and social risk factors, and stroke and myocardial infarction during follow-up. We tested interactions among education level, baseline cognitive performance (Mini-Mental State score), and functional trajectories and ran models stratified by levels of magnetic resonance imaging variables. Mean age was 70.6 (SD, 9.0) years; 19% had PI-SBI, and mean WMHV was 0.68%. Education did not modify associations between cognition and functional trajectories. PI-SBI modified associations between cognition and functional trajectories ( P =0.04) with a significant protective effect of better cognition on functional decline seen only in those without PI-SBI. There was no significant interaction for WMHV ( P =0.8). PI-SBI, and greater WMHV, were associated with 2- to 3-fold steeper functional decline, holding cognition constant. PI-SBI moderated the association between cognition and functional trajectories, with 3-fold greater decline among those with PI-SBI (compared with no PI-SBI) and normal baseline cognition. This highlights the strong and independent association between subclinical markers and patient-centered trajectories over time. © 2018 American Heart Association, Inc.

    1998-01-01

    Over the last few years magnetic resonance imaging (MRI) has developed into a multipurpose imaging technique. In addition to anatomical information, data can be obtained on perfusion, metabolism and imaging of the vascular anatomy. Especially in the field of neuroradiology the possibilities for obtaining multifunctional information from combined MR examinations are promising. In particular, stroke or stroke-related research benefits from these developments. This article reviews the current status and the potential of newly developed MR techniques with regard to the intracranial hemodynamic changes in patients with severe stenosis or occlusion of the internal carotid artery. The combination of MR angiography, perfusion-weighted MRI and MR spectroscopic imaging seems especially useful in the management of the individual patient. (orig.)

    Over the last few years magnetic resonance imaging (MRI) has developed into a multipurpose imaging technique. In addition to anatomical information, data can be obtained on perfusion, metabolism and imaging of the vascular anatomy. Especially in the field of neuroradiology the possibilities for obtaining multifunctional information from combined MR examinations are promising. In particular, stroke or stroke-related research benefits from these developments. This article reviews the current status and the potential of newly developed MR techniques with regard to the intracranial hemodynamic changes in patients with severe stenosis or occlusion of the internal carotid artery. The combination of MR angiography, perfusion-weighted MRI and MR spectroscopic imaging seems especially useful in the management of the individual patient. (orig.) With 4 figs., 176 refs.

    Zacho, J.; Tybjaerg-Hansen, A.; Jensen, J.S.

    2008-01-01

    Background: Elevated levels of C-reactive protein (CRP) are associated with increased risks of ischemic heart disease and ischemic cerebrovascular disease. We tested whether this is a causal association. Methods: We studied 10,276 persons from a general population cohort, including 1786 in whom...... ischemic heart disease developed and 741 in whom ischemic cerebrovascular disease developed. We examined another 31,992 persons from a cross-sectional general population study, of whom 2521 had ischemic heart disease and 1483 had ischemic cerebrovascular disease. Finally, we compared 2238 patients...... with ischemic heart disease with 4474 control subjects and 612 patients with ischemic cerebrovascular disease with 1224 control subjects. We measured levels of high-sensitivity CRP and conducted genotyping for four CRP polymorphisms and two apolipoprotein E polymorphisms. Results: The risk of ischemic heart...

    Full Text Available Dent disease is an x-linked disorder of proximal renal tubular dysfunction that occurs almost exclusively in males. It is characterized by significant, mostly low molecular weight proteinuria, hypercalciuria, nephrocalcinosis, nephrolithiasis, and chronic kidney disease. Signs and symptoms of this condition appear in early childhood and worsen over time. There are two forms of Dent disease, which are distinguished by their genetic cause and pattern of signs and symptoms (type 1 and type 2. Dent disease 2 is characterized by the features described above and also associated with extrarenal abnormalities (they include mild intellectual disability, hypotonia, and cataract. Some researchers consider Dent disease 2 to be a mild variant of a similar disorder called Lowe syndrome.We represent a case of a 3-year old boy with significant proteinuria in the nephrotic range and hypercalciuria. We confirmed Dent disease type 1 by genetic analysis.

  5. Context is everything: From cardiovascular disease to cerebral microbleeds.

    Charidimou, Andreas; Blacker, Deborah; Viswanathan, Anand

    2018-01-01

    Increasingly, our approach to cerebrovascular disease has become blurred by evidence published in literature often without careful consideration of what this evidence implies for specific patients at hand. In this essay, we analyze key contextual issues in cerebrovascular small vessel disease, in an attempt to highlight the symbolic gap that exists between research and clinical practice, a recurring theme in medicine. We highlight the importance of considering context when using data from epidemiologic, neuroimaging, and biomarker studies in determining relevance to the patient at hand. We argue, that while biomarkers and neuroimaging may eventually serve to help to identify individuals with specific cerebrovascular diseases, we must always continue to understand patients in a specific clinical context. These reflections are particularly relevant when considering cerebral microbleeds-a key marker of cerebrovascular small vessel disease whose detection often raises thorny clinical dilemmas.

  7. Celiac disease

    Holtmeier Wolfgang

    2006-03-01

    Full Text Available Abstract Celiac disease is a chronic intestinal disease caused by intolerance to gluten. It is characterized by immune-mediated enteropathy, associated with maldigestion and malabsorption of most nutrients and vitamins. In predisposed individuals, the ingestion of gluten-containing food such as wheat and rye induces a flat jejunal mucosa with infiltration of lymphocytes. The main symptoms are: stomach pain, gas, and bloating, diarrhea, weight loss, anemia, edema, bone or joint pain. Prevalence for clinically overt celiac disease varies from 1:270 in Finland to 1:5000 in North America. Since celiac disease can be asymptomatic, most subjects are not diagnosed or they can present with atypical symptoms. Furthermore, severe inflammation of the small bowel can be present without any gastrointestinal symptoms. The diagnosis should be made early since celiac disease causes growth retardation in untreated children and atypical symptoms like infertility or neurological symptoms. Diagnosis requires endoscopy with jejunal biopsy. In addition, tissue-transglutaminase antibodies are important to confirm the diagnosis since there are other diseases which can mimic celiac disease. The exact cause of celiac disease is unknown but is thought to be primarily immune mediated (tissue-transglutaminase autoantigen; often the disease is inherited. Management consists in life long withdrawal of dietary gluten, which leads to significant clinical and histological improvement. However, complete normalization of histology can take years.

    Radlović Nedeljko

    2013-01-01

    Full Text Available Celiac disease is a multysystemic autoimmune disease induced by gluten in wheat, barley and rye. It is characterized by polygenic predisposition, high prevalence (1%, widely heterogeneous expression and frequent association with other autoimmune diseases, selective deficit of IgA and Down, Turner and Williams syndrome. The basis of the disease and the key finding in its diagnostics is symptomatic or asymptomatic inflammation of the small intestinal mucosa which resolves by gluten-free diet. Therefore, the basis of the treatment involves elimination diet, so that the disorder, if timely recognized and adequately treated, also characterizes excellent prognosis.

  10. Methylenetetrahydrofolate reductase gene polymorphism is not related to the risk of ischemic cerebrovascular disease in a Brazilian population Polimorfismo no gene de metilenetetrahidrofolato redutase não está relacionado com o risco de doença cerebrovascular isquêmica em uma população brasileira

    Samuel Katsuyuki Shinjo

    2007-01-01

    Full Text Available PURPOSE: Data are conflicting concerning the risk for ischemic stroke associated with a common polymorphism in the gene encoding 5,10-methylenetetrahydrofolate reductase C677T, which predisposes carriers to hyperhomocysteinemia. A meta-analysis study suggested that the 5,10-methylenetetrahydrofolate reductase 677TT genotype might have a small influence in determining susceptibility to ischemic stroke. METHODS: We analyzed the 5,10-methylenetetrahydrofolate reductase 677TT genotype polymorphism in Brazilian subjects with ischemic stroke, using a case-control design. RESULTS: We compared 5,10-methylenetetrahydrofolate reductase genotypes in groups of subjects presenting ischemic stroke (n = 127 and normal control (n = 126 and found an odds ratio of 1.97 (95% CI, 0.84-4.64 in a multivariate analysis in which results were adjusted to baseline clinical characteristics of study participants. CONCLUSION: We found that the homozygous 5,10-methylenetetrahydrofolate reductase C677T genotype was not a risk factor for ischemic stroke in these Brazilian subjects.OBJETIVO: Os dados são conflitantes em relação a risco de acidente cerebrovascular associado a polimorfismo do gene 5,10-metilenetetrahidrofolato redutase C677T, o qual predispõe a hiperhomocisteinemia.

    2008-04-01

    Hyperhomocysteinemia has been considered an independent risk factor in the development of stroke. The present study was undertaken to evaluate serum homocysteine levels in patients with cerebrovascular accidents among the Manipuri population and to compare with the normal cases. Ninety-three cerebrovascular accident cases admitted in the hospital were enrolled for the study and twenty-seven age and sex matched individuals free from cerebrovascular diseases were taken as control group. Serum homocysteine levels were estimated by ELISA method using Axis homocysteine EIA kit manufactured by Ranbaxy Diagnostic Ltd. India. The finding suggests that hyperhomocysteinemia is associated with cerebrovascular accident with male preponderance, which increases with advancing age. However, whether hyperhomocysteinemia is the cause or the result of cerebrovascular accidents needs further investigations.

  2. Clinical Significance of Cerebrovascular Biomarkers and White Matter Tract Integrity in Alzheimer Disease: Clinical correlations With Neurobehavioral Data in Cross-Sectional and After 18 Months Follow-ups.

    2015-07-01

    Cerebrovascular risk factors and white matter (WM) damage lead to worse cognitive performance in Alzheimer dementia (AD). This study investigated WM microstructure using diffusion tensor imaging in patients with mild to moderate AD and investigated specific fiber tract involvement with respect to predefined cerebrovascular risk factors and neurobehavioral data prediction cross-sectionally and after 18 months. To identify the primary pathoanatomic relationships of risk biomarkers to fiber tract integrity, we predefined 11 major association tracts and calculated tract specific fractional anisotropy (FA) values. Eighty-five patients with AD underwent neurobehavioral assessments including the minimental state examination (MMSE) and 12-item neuropsychiatric inventory twice with a 1.5-year interval to represent major outcome factors. In the cross-sectional data, total cholesterol, low-density lipoprotein, vitamin B12, and homocysteine levels correlated variably with WM FA values. After entering the biomarkers and WM FA into a regression model to predict neurobehavioral outcomes, only fiber tract FA or homocysteine level predicted the MMSE score, and fiber tract FA or age predicted the neuropsychiatric inventory total scores and subdomains of apathy, disinhibition, and aberrant motor behavior. In the follow-up neurobehavioral data, the mean global FA value predicted the MMSE and aberrant motor behavior subdomain, while age predicted the anxiety and elation subdomains. Cerebrovascular risk biomarkers may modify WM microstructural organization, while the association with fiber integrity showed greater clinical significance to the prediction of neurobehavioral outcomes both cross-sectionally and longitudinally.

  3. Celiac Disease

    Manoochehr Karjoo

    2014-08-01

    Full Text Available Celiac disease also known as gluten-sensitive enteropathy is characterized by intestinal mucosal damage and malabsorption from dietary intake of wheat, rye or barley. Symptoms may appear with introduction of cereal in the first 3 years of life. A second peak in symptoms occurs in adults during the third or forth decade and even as late as eight decade of life. The prevalence of this disease is approximately 1 in 250 adults. The disease is more prevalent in Ireland as high as 1 in 120 adults. The disorder occurs in Arab, Hispanics, Israeli Jews, Iranian and European but is rare in Chinese and African American. To have celiac disease the patient should have the celiac disease genetic markers as HLA DQ 2 and HLA DQ 8. Patient with celiac disease may have 95 per cent for DQ 2 and the rest is by DQ 8. Someone may have the genetic marker and never develops the disease. In general 50 percent with markers may develop celiac disease. To develop the disease the gene needs to become activated. This may happen with a viral or bacterial infection, a surgery, delivery, accident, or psychological stress. After activation of gene cause the tight junction to opens with the release of Zonulin This results in passage of gluten through the tight junction and formation of multiple antibodies and autoimmune disease. This also allows entrance of other proteins and development of multiple food allergies. As a result is shortening, flattening of intestinal villi resulting in food, vitamins and minerals malabsorption.

    O. D. Ostroumova

    2018-01-01

    Full Text Available The immediate and remote benefits of smoking cessation are considered. Within one year after quitting smoking the ischemic heart disease (IHD risk will be 2 folds lower than the risk in smoking patient. Within 15 years the IHD risk declines to non-smoking population level. After 5-15 years after quitting smoking the risk of stroke also declines to non-smoker risk. Smoking cessation prior to cardio surgical intervention leads to reduction of complications incidence by 41%. Smoking cessation significantly reduces the risk of developing stable and unstable angina, acute myocardial infarction, cardiovascular death, transient ischemic attack, ischemic stroke, subarachnoid hemorrhage, intracerebral hemorrhage, peripheral arterial diseases, abdominal aortic aneurysm at any age, in both sexes in comparison to patients who continue to smoke. Smoking cessation is the most cost-effective strategy of cardiovascular disease prevention. Today, the most effective smoking cessation strategy is the identification of smokers and continuous advice on smoking cessation, and offer of the appropriate medication, primarily varenicline. The article contains data from a number of studies showing that varenicline is an effective and safe drug for tobacco dependence treatment, in particular, in patients with acute and chronic cardiovascular disease

    Background. Childhood moyamoya disease is a rare progressive cerebrovascular disease. Objective. To evaluate cerebral hemodynamics using dynamic Gd-DTPA-enhanced imaging in children with moyamoya disease. Materials and methods. Eight children (2-11 years of age) with the clinical and angiographic findings typical of moyamoya disease, before and/or after surgical intervention (pial synangiosis), underwent conventional MR imaging (MRI) and hemodynamic MR imaging (HMRI). HMRI used a spoiled gradient-echo with low flip angle (10 deg) and long TE (TR/TE = 24/15 ms) to minimize T 1 effects and emphasize T 2{sup *} weighting. Raw and calculated hemodynamic images were reviewed. Three-dimensional time-of-flight MR angiography (MRA) and perfusion brain single photon emission computed tomography (SPECT) were also performed. Results. Abnormal hemodynamic maps resulting from vascular stenosis or occlusion and basal collaterals were observed in six patient studies. HMRI depicted perfusion dynamics of affected cerebrovascular territories, detected cortical perfusion deficits, and complemented conventional MRI and MRA. HMRI findings were consistent with those of catheter angiography and perfusion SPECT. Conclusion. Our preliminary experience suggests that HMRI may be of value in the preoperative and postoperative evaluation of surgical interventions in moyamoya disease. (orig.). With 4 figs., 3 tabs.

    Morgellons disease is a rare disease with unknown etiology. Herein, we report the first case of Morgellons disease in Korea. A 30-year-old woman presented with a 2-month history of pruritic erythematous patches and erosions on the arms, hands, and chin. She insisted that she had fiber-like materials under her skin, which she had observed through a magnifying device. We performed skin biopsy, and observed a fiber extruding from the dermal side of the specimen. Histopathological examination showed only mild lymphocytic infiltration, and failed to reveal evidence of any microorganism. The polymerase chain reaction for Borrelia burgdorferi was negative in her serum.

    Chapuis-Taillard, Caroline; de Vallière, Serge; Bochud, Pierre-Yves

    2009-01-07

    In 2008, several publications have highlighted the role of climate change and globalization on the epidemiology of infectious diseases. Studies have shown the extension towards Europe of diseases such as Crimea-Congo fever (Kosovo, Turkey and Bulgaria), leismaniosis (Cyprus) and chikungunya virus infection (Italy). The article also contains comments on Plasmodium knowlesi, a newly identified cause of severe malaria in humans, as well as an update on human transmission of the H5NI avian influenza virus. It also mentions new data on Bell's palsy as well as two vaccines (varicella-zoster and pneumococcus), and provides a list of recent guidelines for the treatment of common infectious diseases.

    2008-11-01

    Hirschsprung disease is a relatively common condition managed by pediatric surgeons. Significant advances have been made in understanding its etiologies in the last decade, especially with the explosion of molecular genetic techniques and early diagnosis. The surgical management has progressed from a two- or three-stage procedure to a primary operation. More recently, definitive surgery for Hirschsprung disease through minimally invasive techniques has gained popularity. In neonates, the advancement of treatment strategies for Hirschsprung disease continues with reduced patient morbidity and improved outcomes.

  12. Crohn's disease.

    Shanahan, Fergus

    2012-02-03

    Crohn\\'s disease is a disorder mediated by T lymphocytes which arises in genetically susceptible individuals as a result of a breakdown in the regulatory constraints on mucosal immune responses to enteric bacteria. Regulation of immune reactivity to enteric antigens has improved understanding of the pathophysiological mechanisms of Crohn\\'s disease, and has expanded therapeutic options for patients with this disorder. Disease heterogeneity is probable, with various underlying defects associated with a similar pathophysiological outcome. Although most conventional drug treatments are directed at modification of host response, therapeutic manipulation of the enteric flora is becoming a realistic option.

    Full Text Available A 2-month-old male infant was found to have Norrie′s disease. The clinical presentation and detailed histological features diagnostic of the disease are discussed. This is the first authentic, histologically proven case of Norrie′s disease from India. The absence of hearing loss and mental retardation at the time of presentation at the early stage of infancy and the fact that the case was sporadic do not detract from the diagnosis. However the child at the age of one year developed hearing loss.

    Coeliac disease is increasingly recognized as a global problem in both children and adults. Traditionally, the findings of characteristic changes of villous atrophy and increased intraepithelial lymphocytosis identified in duodenal biopsy samples taken during upper gastrointestinal endoscopy have...... been required for diagnosis. Although biopsies remain advised as necessary for the diagnosis of coeliac disease in adults, European guidelines for children provide a biopsy-sparing diagnostic pathway.

  10. Ollier disease

    Jüppner Harald

    2006-09-01

    Full Text Available Abstract Enchondromas are common intraosseous, usually benign cartilaginous tumors, that develop in close proximity to growth plate cartilage. When multiple enchondromas are present, the condition is called enchondromatosis also known as Ollier disease (WHO terminology. The estimated prevalence of Ollier disease is 1/100,000. Clinical manifestations often appear in the first decade of life. Ollier disease is characterized by an asymmetric distribution of cartilage lesions and these can be extremely variable (in terms of size, number, location, evolution of enchondromas, age of onset and of diagnosis, requirement for surgery. Clinical problems caused by enchondromas include skeletal deformities, limb-length discrepancy, and the potential risk for malignant change to chondrosarcoma. The condition in which multiple enchondromatosis is associated with soft tissue hemangiomas is known as Maffucci syndrome. Until now both Ollier disease and Maffucci syndrome have only occurred in isolated patients and not familial. It remains uncertain whether the disorder is caused by a single gene defect or by combinations of (germ-line and/or somatic mutations. The diagnosis is based on clinical and conventional radiological evaluations. Histological analysis has a limited role and is mainly used if malignancy is suspected. There is no medical treatment for enchondromatosis. Surgery is indicated in case of complications (pathological fractures, growth defect, malignant transformation. The prognosis for Ollier disease is difficult to assess. As is generally the case, forms with an early onset appear more severe. Enchondromas in Ollier disease present a risk of malignant transformation of enchondromas into chondrosarcomas.

  11. Two adolescent patients with coexistent Graves' disease and Moyamoya disease in Korea.

    Cheon, Chong Kun; Kim, Su Yung; Yoo, Jae-Ho

    2014-06-01

    Moyamoya disease is a cerebrovascular condition that results in the narrowing of the vessels of the circle of Willis and collateral vessel formation at the base of the brain. Although relationships between Graves' disease and cerebrovascular accidents in Moyamoya disease are obscure, the coexistence of the two diseases is noteworthy. Moyamoya disease has been rarely reported in adolescent patients with thyrotoxicosis. Recently, we encountered two adolescent Korean patients with Moyamoya disease associated with Graves' disease who presented with episodic right-sided hemiparesis and syncope. These two girls who had Graves' disease had no history of other diseases or head trauma. A thyroid function test revealed a euthyroid state and a high thyroid-stimulating hormone (TSH) receptor antibody titer at that time. The patients were diagnosed with Moyamoya disease based on brain magnetic resonance angiography and cerebral four-vessel angiography. The patients underwent cranial revascularization by encephalo-duroarterio-synangiosis as soon as a diagnosis was made, which resulted in successful symptom resolution. They fared well and had no additional neurological symptoms as of their last follow-up visits. Here, we report these two cases of confirmed Moyamoya disease complicated by Graves' disease with a review of the literature, and discuss the possible association between the two diseases. To our knowledge, this is the first report in South Korea on Moyamoya disease associated with Graves' disease in adolescents with a euthyroid.

  12. SMOKING AS A RISK FACTOR OF CARDIOVASCULAR AND CEREBROVASCULAR DISEASES: PREVALENCE, IMPACT ON PROGNOSIS, POSSIBLE SMOKING CESSATION STRATEGIES AND THEIR EFFECTIVENESS. Part 1. Smoking Prevalence and Impact on Prognosis

    O. D. Ostroumova

    2017-01-01

    Full Text Available The prevalence of smoking in the Russian Federation is 27.7%. Losses of potential years of life in working age associated with premature death due to smoking in Russia on average are 9 years for men, for women – 5.6 years. Tobacco use is a risk factor for 6 of 8 main causes of death in the world: ischemic heart disease (IHD; cerebral circulation disorders; lower respiratory tract infection; chronic obstructive pulmonary disease; tuberculosis; trachea, bronchus, and lung cancer. The risk of developing IHD in smoking patients is increased by 2-4 times in men and women and in any age group. Myocardial infarction occurs in smoking patients at a younger age, and they have a similar risk of coronary events with patients of older age groups. The increased risk of recurrent coronary events persists with the continuation of smoking in the patient after myocardial infarction. Smoking is associated with a double risk of ischemic stroke and a 2-4-fold increase in the risk of subarachnoid hemorrhage. The risk of peripheral arteries diseases in smokers is increased 3-6 times than this in non-smokers. The mechanisms of development of acute cardiovascular events during smoking include the activation of inflammation, platelet aggregation/thrombogenesis, the sympathetic nervous system, and the development of endothelial dysfunction due to exposure to tobacco smoke components.

    2007-11-07

    Crohn's disease is a long-term chronic condition of the gastrointestinal tract. It is characterised by transmural, granulomatous inflammation that occurs in a discontinuous pattern, with a tendency to form fistulae. The cause is unknown but may depend on interactions between genetic predisposition, environmental triggers, and mucosal immunity. We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of medical treatments in adults to induce remission in Crohn's disease? What are the effects of lifestyle interventions in adults with Crohn's disease to maintain remission? What are the effects of surgical interventions in adults with small-bowel Crohn's disease to induce remission? What are the effects of surgical interventions in adults with colonic Crohn's disease to induce remission? What are the effects of medical interventions to maintain remission in adults with Crohn's disease; and to maintain remission following surgery? We searched: Medline, Embase, The Cochrane Library and other important databases up to March 2006 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 60 systematic reviews, RCTs, or observational studies that met our inclusion criteria. In this systematic review we present information relating to the effectiveness and safety of the following interventions: aminosalicylates, antibiotics, azathioprine/mercaptopurine, ciclosporin, corticosteroids (oral), enteral nutrition, fish oil, infliximab, methotrexate, probiotics, resection, segmental colectomy, smoking cessation, and strictureplasty.

  15. Dent's disease

    Thakker Rajesh V

    2010-10-01

    Full Text Available Abstract Dent's disease is a renal tubular disorder characterized by manifestations of proximal tubule dysfunction, including low-molecular-weight proteinuria, hypercalciuria, nephrolithiasis, nephrocalcinosis, and progressive renal failure. These features are generally found in males only, and may be present in early childhood, whereas female carriers may show a milder phenotype. Prevalence is unknown; the disorder has been reported in around 250 families to date. Complications such as rickets or osteomalacia may occur. The disease is caused by mutations in either the CLCN5 (Dent disease 1 or OCRL1 (Dent disease 2 genes that are located on chromosome Xp11.22 and Xq25, respectively. CLCN5 encodes the electrogenic Cl-/H+ exchanger ClC-5, which belongs to the CLC family of Cl- channels/transporters. OCRL1 encodes a phosphatidylinositol bisphosphate (PIP2 5-phosphatase and mutations are also associated with Lowe Syndrome. The phenotype of Dent's disease is explained by the predominant expression of ClC-5 in the proximal tubule segments of the kidney. No genotype-phenotype correlation has been described thus far, and there is considerable intra-familial variability in disease severity. A few patients with Dent's disease do not harbour mutations in CLCN5 and OCRL1, pointing to the involvement of other genes. Diagnosis is based on the presence of all three of the following criteria: low-molecular-weight proteinuria, hypercalciuria and at least one of the following: nephrocalcinosis, kidney stones, hematuria, hypophosphatemia or renal insufficiency. Molecular genetic testing confirms the diagnosis. The differential diagnosis includes other causes of generalized dysfunction of the proximal tubules (renal Fanconi syndrome, hereditary, acquired, or caused by exogenous substances. Antenatal diagnosis and pre-implantation genetic testing is not advised. The care of patients with Dent's disease is supportive, focusing on the treatment of hypercalciuria and

  17. Sickle Cell Disease with Cyanotic Congenital Heart Disease: Long-Term Outcomes in 5 Children.

    Iannucci, Glen J; Adisa, Olufolake A; Oster, Matthew E; McConnell, Michael; Mahle, William T

    2016-12-01

    Sickle cell disease is a risk factor for cerebrovascular accidents in the pediatric population. This risk is compounded by hypoxemia. Cyanotic congenital heart disease can expose patients to prolonged hypoxemia. To our knowledge, the long-term outcome of patients who have combined sickle cell and cyanotic congenital heart disease has not been reported. We retrospectively reviewed patient records at our institution and identified 5 patients (3 girls and 2 boys) who had both conditions. Their outcomes were uniformly poor: 4 died (age range, 12 mo-17 yr); 3 had documented cerebrovascular accidents; and 3 developed ventricular dysfunction. The surviving patient had developmental delays. On the basis of this series, we suggest mitigating hypoxemia, and thus the risk of stroke, in patients who have sickle cell disease and cyanotic congenital heart disease. Potential therapies include chronic blood transfusions, hydroxyurea, earlier surgical correction to reduce the duration of hypoxemia, and heart or bone marrow transplantation.

  19. Prionic diseases

    Abelardo Q-C Araujo

    2013-09-01

    Full Text Available Prion diseases are neurodegenerative illnesses due to the accumulation of small infectious pathogens containing protein but apparently lacking nucleic acid, which have long incubation periods and progress inexorably once clinical symptoms appear. Prions are uniquely resistant to a number of normal decontaminating procedures. The prionopathies [Kuru, Creutzfeldt-Jakob disease (CJD and its variants, Gerstmann-Sträussler-Scheinker (GSS syndrome and fatal familial insomnia (FFI] result from accumulation of abnormal isoforms of the prion protein in the brains of normal animals on both neuronal and non-neuronal cells. The accumulation of this protein or fragments of it in neurons leads to apoptosis and cell death. There is a strong link between mutations in the gene encoding the normal prion protein in humans (PRNP - located on the short arm of chromosome 20 – and forms of prion disease with a familial predisposition (familial CJD, GSS, FFI. Clinically a prionopathy should be suspected in any case of a fast progressing dementia with ataxia, myoclonus, or in individuals with pathological insomnia associated with dysautonomia. Magnetic resonance imaging, identification of the 14-3-3 protein in the cerebrospinal fluid, tonsil biopsy and genetic studies have been used for in vivo diagnosis circumventing the need of brain biopsy. Histopathology, however, remains the only conclusive method to reach a confident diagnosis. Unfortunately, despite numerous treatment efforts, prionopathies remain short-lasting and fatal diseases.

    2008-01-01

    Morgellons disease, a pattern of dermatologic symptoms very similar, if not identical, to those of delusions of parasitosis, was first described many centuries ago, but has recently been given much attention on the internet and in the mass media. The present authors present a history of Morgellons disease, in addition to which they discuss the potential benefit of using this diagnostic term as a means of building trust and rapport with patients to maximize treatment benefit. The present authors also suggest "meeting the patient halfway" and creating a therapeutic alliance when providing dermatologic treatment by taking their cutaneous symptoms seriously enough to provide both topical ointments as well as antipsychotic medications, which can be therapeutic in these patients.

    Hvas, Christian Lodberg; Jensen, Michael Dam; Reimer, Maria Christina

    2015-01-01

    This national clinical guideline approved by the Danish Society for Gastroenterology and Hepatology describes the diagnosis and treatment of celiac disease (CD) in adults. CD is a chronic immunemediated enteropathy of the small intestine triggered by the ingestion of gluten-containing proteins......, which are found in wheat, rye, and barley. The disease prevalence is 0.5-1.0%, but CD remains under-diagnosed. The diagnosis relies on the demonstration of lymphocyte infiltration, crypt hyperplasia, and villous atrophy in duodenal biopsies. Serology, malabsorption, biochemical markers......, and identification of specific HLA haplotypes may contribute to CD diagnosis. Classical CD presents with diarrhoea and weight loss, but non-classical CD with vague or extraintestinal symptoms is common. The treatment for CD is a lifelong gluten-free diet (GFD), which, in the majority of patients, normalises...

    Full Text Available Background and Purpose: Chronic granulomatous disease (CGD is an inherited disorder of the nicotinamide adenine dinucleotide phosphate (NADPH oxidase complex. This disorder results in recurrent life-threatening bacterial and fungal infections. Aspergillus species are the most common fungal infections in these patients. Case Report: Herein, we present a case of fungal infection in a girl with CGD. We confirmed aspergillosis through the positive microscopic and macroscopic examinations, as well as radiology results. Invasive aspergillosis in this patient with pneumonia, lung abscess, and osteomyelitis of the ribs was not initially treated with amphotericin B (Am B and recombinant interferon-gamma. Conclusion: Among infectious diseases, fungal infections, in particular aspergillosis, remain a serious problem in CGD patients. Considering poor clinical response and deficient immune system, rapid diagnosis of fungal infection and optimizing the treatment of these patients are recommended.

  9. [Addison's disease].

    Quinkler, M

    2012-09-01

    The clinical signs and symptoms of primary adrenal insufficiency are unspecific often causing a delayed diagnosis or even misdiagnosis. In the diagnostic work-up the short synacthen test is regarded as the gold standard. Hydrocortisone and fludrocortisone are the preferred therapy for Addison's disease. The management and surveillance of therapy requires experience and several aspects need to be followed to prevent side effects which might occur due to overtreatment or undertreatment. Very important aspects in therapy are the repeated teaching of the patient and relatives, the issuing of an emergency steroid card and the prescription of a glucocorticoid emergency set. Acute adrenal failure (adrenal crisis), which might be the first manifestation of adrenal insufficiency, is a life-threatening situation requiring immediate glucocorticoid administration and fluid substitution. The most common causes for an adrenal crisis are gastrointestinal infections and fever and discontinuation of glucocorticoid therapy. This article gives an up-to-date overview of diagnostic and therapeutic aspects of Addison's disease.

  10. Joint diseases

    Weissman, S.D.

    1989-01-01

    The authors discuss how x-ray examination is essential in the diagnosis and evaluation of the arthritides. Most arthritides are first suspected by the clinician, and x-ray evaluation of these entities along with laboratory testing is important for confirmation of the clinical diagnosis and in staging of the disease process. Several arthritides are often diagnosed first by the podiatrist on x-ray evaluation, including pseudogout, ankylosing spondylitis, early rheumatoid arthritis, degenerative joint disease, and tuberculosis of bone. The joint responds to insult in only a limited number of ways that become apparent on x-ray. The soft tissues surrounding the joint, the articulating bones, and alignment of the joint space may all be involved by the arthritic process. On roentgenographic examination, the soft tissues must be examined for edema, masses, calcifications, and atrophy. The articulating bones must be examined for demineralization, erosions, osteophytes, periosteal reaction, cysts and sclerosis

    Regional cerebral blood flow was measured using N-isopropyl- 123 I-iodoamphetamine with single-photon emission computed tomography (CT) in 16 aged patients with noninsulin-dependent diabetes mellitus (NIDDM, average age 72.8 years, average fasting plasma glucose 7.7 mmol/L), and 12 nondiabetic subjects (71.6 years, 5.3 mmol/L). None had any history of a cerebrovascular accident. Systolic blood pressure (SBP), total cholesterol, and triglyceride levels did not differ between groups. Areas of hypoperfusion were observed in 14 diabetic patients (12 patients had multiple lesions) and in 6 nondiabetic subjects (3 had multiple lesions). Areas where radioactivity was greater than or equal to 65% of the maximum count of the slice was defined as a region with normal cerebral blood flow (region of interest A, ROI-A), and areas where the count was greater than or equal to 45% were defined as brain tissue regions other than ventricles (ROI-B). The average ROI-A/B ratio of 16 slices was used as a semiquantitative indicator of normal cerebral blood flow throughout the entire brain. Mean ROI-A/B ratio was 49.6 +/- 1.7% in the diabetic group, significantly lower than the 57.9 +/- 1.6% at the nondiabetic group (p less than 0.005). The ratio was inversely correlated with SBP (r = -0.61, p less than 0.05), total cholesterol (r = -0.51, p less than 0.05), and atherogenic index (r = -0.64, p less than 0.01), and was positively correlated with high-density lipoprotein (HDL) cholesterol (r = 0.51, p less than 0.05) in the diabetic, but not the nondiabetic group. These observations suggest that the age-related reduction in cerebral blood flow may be accelerated by a combination of hyperglycemia plus other risk factors for atherosclerosis

    1988-01-01

    Diseases found in 2,104 consequetive inpatients between April 1981 and March 1986 were statistically analyzed. The incidence of disease increased in the following order: diabetes mellitus > heart disease > cerebrovascular disorder > malignancy > hypertensive disease > arteriosclerosis > osteoarthritis. Malignancy is the most common cause of death or the highest mortality rate, followed by heart disease, cerebrovascular disorder, and liver cirrhosis. For the number of autopsy, the order of diseases was: malignancy, cardiovascular disease, gastrointestinal disease, respiratory tract disease, endocrine disease, and hematopoietic disease; for the incidence of autopsy, the order was: liver cirrhosis, diabetes mellitus, cerebrovascular disorder, malignancy, and heart disease. Malignancy accounted for 23 % of the inpatients. The incidence of malignancy increased in the following organs: stomach > liver > colon > lung > breast > biliary tract > esophagus. The incidence of leukemia was low. There was no definitive correlation between the incidence of malignancy and exposure distance, although the incidence of breast cancer tended to be high in the group exposed at ≤2,000 m from the hypocenter. According to age class, gastric cancer was frequent in patients less than 40 years and more than 60 years. Liver cancer was the most common in the sixtieth decade of life of men. The incidence of lung cancer increased with advancing age; the incidence of breast cancer was higher in younger patients. (Namekawa, K.)

  1. Thyroid diseases

    Noma, Koji

    1992-01-01

    This chapter reviews the correlation between thyroid disease, other than cancer, and radiation in the literature. Radiation-induced thyroid disturbance is discussed in the context of external and internal irradiation. External irradiation of 10 to 40 Gy may lower thyroid function several months or years later. Oral administration of I-131 is widely given to patients with Basedow's disease; it may also lower thyroid function with increasing radiation doses. When giving 70 Gy or more of I-131, hypothyroidism has been reported to occur in 20-30% and at least 10%. Thyroiditis induced with internal I-131 irradiation has also been reported, but no data is available concerning external irradiation-induced thyroiditis. The incidence of nodular goiter was found to be several ten times higher with external irradiation than internal irradiation. Thyroid disturbance is correlated with A-bomb survivors. A-bomb radiation can be divided into early radiation within one minute after A-bombing and the subsequent residual radiation. Nodular goiter was significantly more frequent in the exposed group than the non-exposed group; it increased with increasing radiation doses and younger age (20 years or less) at the time of exposure. The incidence of decrease in thyroid function was higher with increasing radiation doses. However, in the case of Nagasaki, the incidence of hypothyroidism was significantly higher in the low-dose exposed group, especially A-bomb survivors aged 10-39 at the time of exposure and women.

  3. The neuropsychological profile of Alzheimer disease.

    Weintraub, Sandra; Wicklund, Alissa H; Salmon, David P

    2012-04-01

    Neuropsychological assessment has featured prominently over the past 30 years in the characterization of dementia associated with Alzheimer disease (AD). Clinical neuropsychological methods have identified the earliest, most definitive cognitive and behavioral symptoms of illness, contributing to the identification, staging, and tracking of disease. With increasing public awareness of dementia, disease detection has moved to earlier stages of illness, at a time when deficits are both behaviorally and pathologically selective. For reasons that are not well understood, early AD pathology frequently targets large-scale neuroanatomical networks for episodic memory before other networks that subserve language, attention, executive functions, and visuospatial abilities. This chapter reviews the pathognomonic neuropsychological features of AD dementia and how these differ from "normal," age-related cognitive decline and from other neurodegenerative diseases that cause dementia, including cortical Lewy body disease, frontotemporal lobar degeneration, and cerebrovascular disease.

    Full Text Available A 17-year-old male, who gave up his favorite sport cricket and started playing football, presented with one-year history of slowly progressive atrophic weakness of forearms and hands. Neurological examination showed weak and wasted arms, forearms and hand but no evidence of pyramidal tract, spinothalmic tract and posterior column lesions. Plain cervical spine radiographs showed no abnormal findings. Cervical magnetic resonance imaging (MRI showed asymmetric cord atrophy; images obtained with neck flexed showed the anterior shifting of the posterior wall of the lower cervical dural sac resulting in cord compression. These findings suggest Hirayama disease, a kind of cervical myelopathy related to the flexion movements of the neck.

  7. Predictive factors for cerebrovascular accidents after thoracic endovascular aortic repair.

    2009-12-01

    Cerebrovascular accidents are devastating and worrisome complications after thoracic endovascular aortic repair. The aim of this study was to determine cerebrovascular accident predictors after thoracic endovascular aortic repair. Between January 2001 and June 2008, 76 patients treated with thoracic endovascular aortic repair were prospectively enrolled. The study cohort included 61 men; mean age was 65.4 +/- 16.8 years. All patients underwent a specific neurologic assessment on an hourly basis postoperatively to detect neurologic deficits. Cerebrovascular accidents were diagnosed on the basis of physical examination, tomography scan or magnetic resonance imaging, or autopsy. Cerebrovascular accidents occurred in 8 (10.5%) patients, including 4 transient ischemic attack and 4 major strokes. Four cases were observed within the first 24-hours. Multivariable analysis revealed that anatomic incompleteness of the Willis circle (odds ratio [OR] 17.19, 95% confidence interval [CI] 2.10 to 140.66), as well as the presence of coronary artery disease (OR 6.86, 95 CI% 1.18 to 40.05), were independently associated with postoperative cerebrovascular accident development. Overall hospital mortality was 9.2%, with no significant difference for patients hit by cerebrovascular accidents (25.0% vs 7.3%, p = 0.102). Preexisting coronary artery disease, reflecting a severe diseased aorta and anomalies of Willis circle are independent cerebrovascular accident predictors after thoracic endovascular aortic repair procedures. A careful evaluation of the arch vessels and cerebral vascularization should be mandatory for patients suitable for thoracic endovascular aortic repair.

    2013-01-01

    Osler's disease, also known as hereditary hemorrhagic telangiectasia (HHT) and Osler-Weber-Rendu syndrome, is an autosomal dominant disorder leading to abnormal blood vessel formation in the skin, mucous membranes and often in organs, such as the lungs, liver and brain (arteriovenous malformations AVM). Various types are known. Patients may present with epistaxis. Teleangiectasia can be identified by visual inspection during physical examination of the skin or oral cavity or by endoscopy. Diagnosis is made after clinical examination and genetic testing based on the Curacao criteria. Modern imaging modalities, such as computed tomography (CT) or magnetic resonance imaging (MRI) have become more important as they can depict the AVMs. Pulmonary AVMs can be depicted in CT imaging even without the use of a contrast agent while other locations including the central nervous system (CNS) usually require administration of contrast agents. Knowledge of possible clinical manifestations in various organs, possible complications and typical radiological presentation is mandatory to enable adequate therapy of these patients. Interventional procedures are becoming increasingly more important in the treatment of HHT patients. (orig.) [de

  7. Non-Alcoholic Fatty Liver Disease: The Emerging Burden in Cardiometabolic and Renal Diseases.

    Han, Eugene; Lee, Yong Ho

    2017-12-01

    As the number of individuals with non-alcoholic fatty liver disease (NAFLD) has increased, the influence of NAFLD on other metabolic diseases has been highlighted. Accumulating epidemiologic evidence indicates that NAFLD not only affects the liver but also increases the risk of extra-hepatic diseases such as type 2 diabetes mellitus, metabolic syndrome, dyslipidemia, hypertension, cardiovascular or cerebrovascular diseases, and chronic kidney disease. Non-alcoholic steatohepatitis, an advanced type of NAFLD, can aggravate these inter-organ relationships and lead to poorer outcomes. NAFLD induces insulin resistance and exacerbates systemic chronic inflammation and oxidative stress, which leads to organ dysfunction in extra-hepatic tissues. Although more research is needed to identify the pathophysiological mechanisms and causal relationship between NAFLD and cardiometabolic and renal diseases, screening for heart, brain, and kidney diseases, risk assessment for diabetes, and a multidisciplinary approach for managing these patients should be highly encouraged.

  8. Renal disease in patients with celiac disease.

    Boonpheng, Boonphiphop; Cheungpasitporn, Wisit; Wijarnpreecha, Karn

    2018-04-01

    Celiac disease, an inflammatory disease of small bowel caused by sensitivity to dietary gluten and related protein, affects approximately 0.5-1% of the population in the Western world. Extra-intestinal symptoms and associated diseases are increasingly recognized including diabetes mellitus type 1, thyroid disease, dermatitis herpetiformis and ataxia. There have also been a number of reports of various types of renal involvement in patients with celiac disease including diabetes nephropathy, IgA nephropathy, membranous nephropathy, membranoproliferative glomerulonephritis, nephrotic syndrome related to malabsorption, oxalate nephropathy, and associations of celiac disease with chronic kidney disease and end-stage kidney disease. This review aims to present the current literature on possible pathologic mechanisms underlying renal disease in patients with celiac disease.

  9. [The systemic and differential psychoprophylaxis of vascular brain diseases in the workers of an industrial enterprise].

    Andreev, A G

    1994-01-01

    Basing on epidemiological, prospective and clinicopsychological data obtained on 1900 industrial workers of Nizhni Novgorod city, the system of psychoprophylaxis and psychotherapy of cerebrovascular diseases has been developed. The system of psychoprophylaxis was used with consideration of the disease stage and phase, psychic and psychosomatic status in risk groups, in subjects with initial and apparent symptoms of cerebrovascular failure. The psychoprophylactic system proved effective in the conditions of a large industrial enterprise.

  10. Vertebrobasilar Dolichoectasia in Fabry Disease

    Juan Politei

    2014-06-01

    Full Text Available Introduction: Fabry disease (FD is a lysosomal storage disorder associated with marked cerebrovascular involvement. Conventional magnetic resonance imaging (MRI shows different abnormalities, like white matter lesions that may already be present at an early stage in the disease. Aim: To present observations from a series of brain MRIs performed among a cohort of patients with FD and the relationship of imaging abnormalities with the presence of cardiovascular risk factors (CVRFs. Methods: A total of 70 patients with FD (43 women were enrolled. The cardiac, renal, ophthalmic, and peripheral nerve functioning was assessed. The MRI evaluation included assessment for evidence of ischemia, microbleeds, pulvinar sign, Arnold-Chiari type 1 malformation, and vertebrobasilar dolichoectasia (VBD. The presence or absence of CVRFs was examined for all patients. Results: Renal involvement was found in 60%, cardiac compromise in 30%, cornea verticillata in 91.4%, and acroparesthesias in 87.1% of patients. Brain MRI analysis found evidence of cerebral ischemic injury in 25.9% of men and 30.2% of women. Vertebrobasilar dolichoectasia was observed in imaging from 55.5% of men and 34.8% of women. The logistic regression analysis adjusted for cardiovascular risks factors, using ischemia or VBD as a dependent variable, showed no statistically significant results. Discussion: Our results have demonstrated cerebrovascular involvement before the third decade in many patients with FD. This study is further evidence confirming that women are not just carriers of FD and should be followed clinically and evaluated comprehensively to monitor for disease burden and progression. Although silent brain ischemias in MRI should be included as a key feature for the diagnoses of FD, VBD is an earlier and frequent sign.

  11. Hematopoietic diseases

    Dohi, Hiroo

    1992-01-01

    A-bombing panicked many people with anxiety because they suffered from various symptoms after A-bombing (ie, they generally called them A-bomb disease). In this chapter, major two conditions (ie, leukopenia and anemia), which caused their symptoms, are reviewed based on the early data soon after A-bombing. According to the chronological changes in both white blood cell (WBC) and red blood cell (RBC) counts, both leukopenia and anemia are discussed. The findings can be divided into acute (one week or at least 10 days), subacute (2 weeks to one month), and delayed (thereafter) periods. During an acute period, some exposed even at ≤200 m from the hypocenter showed WBC count of 6,000/mm 3 or more one week after exposure but others exposed at 1,500-2,000 m showed WBC count of less than 3,000/mm 3 , suggesting the influence of shielding on WBC count. WBC count sometimes became the lowest during a subacute period, although it was normal during an acute period. A survey for WBC count during a delayed period (one year later) showed that WBC count of less than 4,000/mm 3 was more frequent in the exposed group (78/523 A-bomb survivors, 14.9%) than the non-exposed group (6/173 persons, 3.5%). In the exposed group, leukopenia was independent of distance and symptoms at the time of exposure. For anemia, there was no data available during an acute period. Anemia frequently occurred during a subacute period. Morphological abnormality of RBC tended to be high in death cases. A delayed survey on anemia 10 years after exposure showed that there was no statistically significant difference in any of the factors, such as hemoglobin, RBC count, hematocrit, mean corpuscular volume and mean corpuscular hemoglobin, between the exposed and non-exposed groups.

  13. Association between periodontal diseases and systemic diseases

    Patrícia Weidlich

    2008-08-01

    Full Text Available Current evidence suggests that periodontal disease may be associated with systemic diseases. This paper reviewed the published data about the relationship between periodontal disease and cardiovascular diseases, adverse pregnancy outcomes, diabetes and respiratory diseases, focusing on studies conducted in the Brazilian population. Only a few studies were found in the literature focusing on Brazilians (3 concerning cardiovascular disease, 7 about pregnancy outcomes, 9 about diabetes and one regarding pneumonia. Although the majority of them observed an association between periodontitis and systemic conditions, a causal relationship still needs to be demonstrated. Further studies, particularly interventional well-designed investigations, with larger sample sizes, need to be conducted in Brazilian populations.

  16. CEREBROVASCULAR DISEASES: THE POSSIBILITIES AND EFFICIENCY OF METABOLIC THERAPY

    Kh. Ya. Umarova

    2014-07-01

    Full Text Available Acute and chronic brain ischemia is accompanied by complex metabolic rearrangements in the neurons. The ability of the cells to survive is largely determined by the presence of energy substrates and oxygen, the synthesis of neurotransmitters, and some other factors. The increasedpersistence of nerve tissue in ischemia and chances of recovering the impaired function can be achieved by the use of neuroprotective and neurotrophic agents. The efficiency of neurometabolic therapy is considered using Ceraxon and Actovegin as an example. It is emphasized that theefficiency of their administration can be achieved by the mandatory concurrent use of a wide range of nondrug treatments.

  17. Homocysteine and cerebrovascular accidents.

    Datta, Saikat; Pal, Salil K; Mazumdar, Hirak; Bhandari, Biswanath; Bhattacherjee, Sharmistha; Pandit, Sudipta

    2009-06-01

    Hyperhomocysteinaemia is rapidly emerging as an important risk factor for coronary artery disease, possibly because of its propensity to accelerate atherosclerosis. Whether it is also a risk factor for cerebrovascular accidents (CVA) is a matter of debate till now, as there are conflicting results of the various prospective studies. The present study was performed to correlate the levels of plasma homocysteine levels with that of ischaemic and haemorrhagic CVA. Forty-two cases of CVA were randomly selected over a period of one year, and their risk factors were assessed. It was observed that serum homocysteine levels were significantly raised in those with intracerebral infarcts when compared to those with intracerebral haemorrhage, although homocysteine levels didn't prove to be prognostically significant.

  19. Transcatheter aortic valve implantation and cerebrovascular accidents.

    Stortecky, Stefan; Wenaweser, Peter; Windecker, Stephan

    2012-09-01

    Transcatheter aortic valve implantation (TAVI) is an evidence-based treatment alternative for selected high-risk patients with symptomatic severe aortic stenosis as acknowledged in the most recent edition of the ESC Guidelines on Valvular Heart Disease 2012. However, periprocedural complications and in particular cerebrovascular accidents remain a matter of concern. While transcatheter heart valve technology continuously improves and the development of novel and even less invasive implantation techniques is on-going, cerebrovascular events complicating TAVI may abrogate the usual improvement in terms of prognosis and quality of life. This article describes the incidence of cerebrovascular events after cardiovascular procedures, provides an overview of the pathophysiological mechanisms as well as the impact on outcomes and provides some insights into preventive strategies as well as the acute management of these events.
