Detection of post-stroke visual field loss by quantification of the retrogeniculate visual pathway
This study explored the association between the microstructural integrity of the retrogeniculate pathway and visual field loss in disabling stroke patients undergoing inpatient rehabilitation. Thirty patients with stroke lesions involving the retrogeniculate visual pathway were included. The degree of visual field loss was determined by the visual field index and mean deviation using automated perimetry.

Computed tomography versus short sequence magnetic resonance imaging in acute ischaemic stroke
It is undisputable that the acute management of stroke requires a fast and accurate diagnostic imaging modality. We read with interest and congratulate Kumar et al. on their article discussing the superiority and benefits of the use of magnetic resonance imaging (MRI) in acute ischaemic stroke (AIS) [1]. The authors suggest that MRI can improve the diagnostic accuracy of computed tomography (CT) negative AIS and allow better selection of patients for reperfusion therapies. Moreover, MRI may help avoid hospital admissions for patients with stroke mimics, facilitate earlier discharge, reduce overall hospital costs and play a...

CHADS2 score predicts functional outcome of stroke in patients with a history of coronary artery disease
Abstract: Background: The aim of this study was to evaluate the efficacy of the CHADS2 scoring system as a prognostic tool for stroke patients with a prior history of coronary artery disease (CAD).Methods: We enrolled 148 acute ischemic stroke patients (mean age, 74.2years; males, 77.0%) with a history of CAD. Pre-admission CHADS2 scores were calculated by assigning a single point for the presence of congestive heart failure, hypertension, age ≥75years, and diabetes; and assigning 2 points for a prior history of stroke or transient ischemic attack. Comparisons were made between patients with poor and good 3-month functio...

Impact of diabetes and prediabetes on the short-term prognosis in patients with acute ischemic stroke
Abstract: Objective: We aimed to explore the association between abnormal glucose metabolism such as diabetes, prediabetes, and short-term prognosis in patients with acute ischemic stroke.Methods: Of 242 consecutive acute ischemic stroke patients, a 75-g oral glucose tolerance test was administered to 116 patients without previously diagnosed diabetes. One hundred forty patients were classified into diabetes, 52 patients were prediabetes (impaired glucose tolerance or impaired fasting glucose or both), and 50 patients were normal glucose tolerance (NGT). The association between each glycemic status and early neurological d...

Recent advances in acute hearing loss due to posterior circulation ischemic stroke
Abstract: Acute hearing loss (AHL) has traditionally been considered to be a neglected and underestimated symptom of stroke. However, because the blood supply to the auditory system originates from the vertebrobasilar system, stroke in the distribution of the vertebrobasilar circulation can present with acute hearing loss (AHL) and/or tinnitus. Approximately one-tenth of vertebrobasilar ischemic stroke (VBIS) is accompanied by AHL. Sometimes, AHL is a warning symptom of impending VBIS (mainly in the anterior inferior cerebellar artery). In this case, the MRI is normal, and the clinician must rely on other clinical features...

Risk factors and acute ischemic stroke subtypes
Conclusion: Specific AIS etiology and blood characteristics associated independently to the youngest and oldest AIS patients, respectively. Chronic kidney disease was a specific predictor of cerebellum–brainstem AIS. AIS mortality showed peculiar association with the oldest patients.

Pilot assessment of a comfort scale in stroke patients
Conclusions: The scale can help to define difficulties in daily living situations and identify opportunities for intervention in stroke patients.

Blood pressure variability and stroke outcome in patients with internal carotid artery occlusion
Abstract: Purpose: The aim of this study was to evaluate the relationship between arterial blood pressure (BP) variability during the acute phase and the 3-month outcome in ischemic stroke patients with internal carotid artery (ICA) occlusion.Methods: At least 10 BP measurements during the first 48h after stroke onset were obtained in 89 patients with ICA occlusion. BP profile was described using various parameters: average of recordings, maximum (max), minimum (min), difference between max and min (max−min), standard deviation (SD) and coefficient of variation (CV) for both systolic and diastolic BP. Outcome at 3months ...

Reliability of transcranial magnetic stimulation induced corticomotor excitability measurements for a hand muscle in healthy and chronic stroke subjects
Abstract: Transcranial magnetic stimulation (TMS) has been used to evaluate neuroplastic changes in the brain in clinical trials. The purpose of this study was to establish the test–retest reliability of 4 TMS measures of corticomotor excitability — (1) resting motor threshold, (2) slope of input–output curve, (3) peak motor evoked potential amplitude, and (4) cortical silent period duration for the corticospinal projections to the first dorsal interosseous of the contralateral hand. Fourteen healthy subjects (mean age 27.4years) and 27 subjects with stroke-induced upper limb hemiparesis (mean age 61.3years) complete...

Could immediate blood pressure reduction after acute ischemic stroke prevent early recurrent strokes?
We read, with great interest, the JAMA article by Dr. He and his colleagues suggesting that modest blood pressure (BP) reduction by 10–25% within the first 24h after randomization and maintained at less than 140/90mmHg for an average hospitalization period of 13days did not reduce the likelihood of death and major disability at 14days or hospital discharge, compared with the absence of antihypertensive medication. The study results provide important evidence about the utility of BP management for enhancing two key outcomes in the immediate post-stroke period. While the conclusions seem appropriate, the authors do not dis...

Matrix metalloproteinase-1 and matrix metalloproteinase-12 gene polymorphisms and the risk of ischemic stroke in a Tunisian population
In this study, we investigated, for the first time, the association between MMP-1-16071G/2G, MMP-12 -82A/G and MMP-12 1082A/G genotypes and haplotypes and the risk of ischemic stroke (IS) among patients with type 2 diabetes mellitus (T2DM). To examine whether these genetic polymorphisms are associated with susceptibility to IS, 196 patients with IS and 192 controls were examined by PCR-based RFLP. When the analyses were adjusted for multiple risk factors, no interaction between T2DM and MMP-1-1607 1G/2G polymorphism on the risk of ischemic stroke was found (p=0.074). However, MMP-12 polymorphisms genotypes were associated ...

Screening of the NOS3 gene identifies the variants 894G/T, 1998C/G and 2479G/A to be associated with acute onset ischemic stroke in young Asian Indians
Abstract: Introduction: Nitric oxide levels and NOS3 gene variants play a pivotal role in the development of vascular diseases/stroke. We attempted to determine the role of NOS3 gene variants and plasma NO levels towards the development of ischemic stroke in young Asian-Indians.Methods: One hundred ischemic stroke patients and 200 age and sex matched control study subjects were screened for NOS3 gene variants using SSCP [single stranded confirmation polymorphism] and PCR based techniques. Plasma NO metabolites [NOx] were evaluated for the investigated population.Results: Significantly higher NOx levels were observed in con...
