Malaria is a severe disease and kills over 400,000 people each year. Malarial complications are the main cause of death and include cerebral malaria and malaria-associated acute respiratory distress syndrome (MA-ARDS). Despite antimalarial treatment, lethality rates of MA-ARDS are still between 20 and 80%. Patients develop pulmonary edema with hemorrhages and leukocyte extravasation in the lungs. The vascular endothelial growth factor-A (VEGF-A) and the placental growth factor (PlGF) are vascular permeability factors and may be involved in the disruption of the alveolar-capillary membrane, leading to alveolar edema...

Kosei Hashimoto, Akira Uno, Ami Sambai, Go Mizumoto
We report a patient with aphasia, caused by cerebral hemorrhage, who probably used the nonsemantic lexical route when reading words aloud. To investigate the mechanisms underlying her reading dysfunction, we analyzed her reading abilities using the Dual-Route Cascaded Model. Language tests resulted in low correct percentages for both reading comprehension and reading nonwords aloud, suggesting problems in the semantic system and the nonlexical route. Conversely, the patient showed high scores on the reading words aloud task...

PURPOSE OF REVIEW: Cerebral cavernous malformations (CCMs) are common vascular abnormalities often discovered on imaging as an incidental finding. The most common clinical presentations of CCMs include seizure, headache, focal neurological deficits, and intracranial hemorrhage. This article discusses the most recent guidelines including imaging diagnostic criteria and radiographic standards of CCMs and reviews the utility of currently available imaging techniques. RECENT FINDINGS: Gradient echo T2*-weighted imaging and susceptibility-weighted imaging are the recommended imaging protocols for evaluation of suspected CCMs...

BACKGROUND AND PURPOSE: 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). METHODS: Using the 2000-2012 NIS, we performed a case-control study matching cases of Marfan syndrome to controls without such a diagnosis...

BACKGROUND: Prospective studies of unruptured aneurysms have shown very low rates of rupture for small aneurysms (<10 mm) and suggested that the risk of treatment outweighs benefit. However, common clinical practice shows that patients with aneurysmal subarachnoid hemorrhage (aSAH) frequently have small aneurysms. OBJECTIVE: To investigate trends in size and location of ruptured aneurysms over a 25-yr period. METHODS: A prospective, Institutional Review Board-approved database of all patients presenting to our institution with aSAH from 1991 to 2016 was analyzed...

OBJECTIVE It has been suggested that increased body mass index (BMI) may confer a protective effect on patients who suffer from aneurysmal subarachnoid hemorrhage (aSAH). Whether the modality of aneurysm occlusion influences the effect of BMI on patient outcomes is not well understood. The authors aimed to compare the effect of BMI on outcomes for patients with aSAH treated with surgical clipping versus endovascular coiling. METHODS The authors retrospectively reviewed the outcomes for patients admitted to their institution for the management of aSAH treated with either clipping or coiling...

The objective of this study is to analyze CSF red blood cell (RBC) count from first-attempt lumbar punctures and to analyze parameters associated with first-attempt lumbar punctures and hemorrhagic lumbar puncture. This is a prospective analysis of consecutive patients who underwent lumbar puncture for any reason other than suspected acute subarachnoid hemorrhage. Analyzed parameters were the following: age, indication for lumbar puncture, aPTT ratio, PTT, platelet count, patient's position, needle type (atraumatic/standard), needle diameter, person performing lumbar puncture (medical student/resident/attending physician), number of lumbar levels punctured, necessity of needle repositioning, CSF RBC and white blood cell count, and protein level...

Defects in vascular integrity in cerebrovasculature lead to serious pathologies including hemorrhagic stroke. The stability of cell adhesion junctions and actin-myosin contractile machinery are two major determinants for the integrity of endothelial monolayer. Here we have evaluated the protective effects of tanshinone I (Tan I), a lipophilic compound presents in Salvia miltiorrhiza, against atorvastatin-induced cerebral hemorrhage in zebrafish in vivo, and further dissected the molecular mechanisms in HUVECs...

OBJECTIVE: Exposure to selective serotonin reuptake inhibitors (SSRIs) has been shown to increase the risk of stroke. In this study, we investigated age and time effects on the risk of first onset stroke in SSRI-exposed (SSRIEXP) adult subjects. METHODS: We analyzed an 8-year cohort from the National Health Insurance Research Database, Taiwan. Patients were defined as SSRIEXP subjects if they received SSRI prescriptions for at least 2 consecutive months during January 1, 2001, to December 31, 2007...

BACKGROUND: Anterior and posterior circulation atherosclerosis differ in vascular risk factors and stroke mechanisms. However, few studies have compared the pathological features between these lesions. Using a series of intracranial artery specimens, we characterized the intracranial atherosclerotic lesions and compared pathological features among different arteries of the intracranial vasculature. METHODS: Intracranial large arteries of 32 consecutively recruited autopsy cases of Chinese adults aged 45 years or older were examined pathologically using routine histology and immunostaining, to characterize the pathological features of the atherosclerotic lesions...

BACKGROUND: Time-resolved rotational angiography (t-RA) enables interventionists to better comprehend complex arteriovenous malformations (AVMs), thereby facilitating endovascular treatment. However, its use in evaluating hemodynamic changes has rarely been explored. OBJECTIVE: This study uses t-RA to estimate intravascular flow in patients with AVM to compare this with flow in the normal population. METHODS: Patients with available t-RA scans were prospectively categorized into one of three groups: hemorrhagic AVM, non-hemorrhagic AVM and control...

Cerebral amyloid angiopathy is diagnosed in stroke units after lobar intracerebral hemorrhage. CAA can also be diagnosed in memory clinics when patients are referred for cognitive impairment assessment, and may be a reason for admission to emergency or neurology departments because of rapidly progressive cognitive or neurological decline, or a transient focal neurological episode. CAA may even be observed in older community-dwelling individuals. Neuropsychological impairment in CAA has been described over the past 20 years...
