Sickle Mice Are Sensitive to Hypoxia/Ischemia-Induced Stroke but Respond to Tissue-Type Plasminogen Activator Treatment Basic Sciences
Conclusions—Sickle mice are sensitive to hypoxia/ischemia-induced cerebral infarct but benefit from thrombolytic treatment. An increased resistive index in carotid arteries may be an early marker of sickle cell vasculopathy.

Increasing the Risk of Stroke by Opium Addiction
Stroke is among the leading causes of mortality and morbidity in the world. Besides the identified risk factor, Ischemic stroke evidence show drug use develops or exacerbates the atherosclerotic process. The current study aimed at comparing cerebrovascular ultrasounds ’ changes in addicted and nonaddicted people who developed ischemic stroke.

Stroke and Cardio-ankle Vascular Stiffness Index
Background: We investigated the relationship between stroke and cardio-ankle vascular stiffness index (CAVI), a novel noninvasive measure of vascular stiffness.Methods: Eighty-five patients with cerebrovascular disease who underwent CAVI were enrolled in the current study. They were 63 men and 22 women with a mean age of 70.0 ± 10.8 years. They were divided into 4 groups according to neurologic abnormalities and magnetic resonance imaging (MRI) findings: 12 with transient ischemic attack (TIA), 26 with white matter ischemic lesions (WMLs), 17 with large artery atherosclerosis, and 30 with small vessel occlusion. Eight hun...

Progression Rate and Ipsilateral Neurological Events in Asymptomatic Carotid Stenosis Clinical Sciences
Conclusions— Fast rates of progression of carotid luminal narrowing should be interpreted as a sign of significantly increased risk of future ipsilateral neurological events.

Optical Bedside Monitoring of Cerebral Blood Flow in Acute Ischemic Stroke Patients During Head-of-Bed Manipulation Clinical Sciences
Conclusions— A lower HOB angle results in an increase in cortical CBF without a significant change in arterial flow velocity in AIS, but there is variability across patients in this response. Bedside CBF monitoring with diffuse correlation spectroscopy provides a potential means to individualize interventions designed to optimize CBF in AIS.

Provoked Right-to-Left Shunt in Patent Foramen Ovale Associates With Ischemic Stroke in Posterior Circulation Brief Reports
Conclusions— The predominance of posterior-circulatory infarction in provoked RLS patients suggests that the Valsalva maneuver may promote RLS and paradoxical embolization to the posterior circulation.

An Ultrasound Investigation of Tongue Shape in Stroke Patients with Lingual Hemiparalysis
Stroke can cause hemilateral paresis of the tongue. The present study investigated the functional consequences of a lingual hemiparalysis on the symmetry and the grooving of the tongue in the coronal plane during the production of vowel-consonant-vowel sequences. The hypotheses were that, because of the lingual hemiparalysis, the stroke patients' tongue shapes would be (1) more asymmetrical and (2) less grooved than the tongues of the control speakers.

Silent Brain Infarctions and Leukoaraiosis in Patients With Retinal Ischemia Brief Report
Conclusions—Silent cerebral ischemia is present in about 1 in 7 patients with retinal ischemia. The high rate of symptomatic internal carotid artery stenosis suggests that large artery atherosclerosis plays a major role in the pathogenesis of acute retinal ischemia.

Comparison of Therapeutic Ultrasound and Radial Shock Wave Therapy in the Treatment of Plantar Flexor Spasticity After Stroke: A Prospective, Single-blind, Randomized Clinical Trial
This study aimed to compare the effects of therapeutic ultrasound (US) and radial extracorporeal shock wave therapy (rESWT) in the treatment of plantar flexor spasticity after stroke. Materials and Methods: In this prospective, single-blind, randomized clinical trial, 32 patients (age range 42-78 years; male 19) with stroke were randomly divided into two groups: The US group (n  = 16) received the continuous ultrasound, intensity 1.5 w/cm2, frequency 1MHz, and duration 10 minutes. The rESWT group (n = 16) was treated with rESWT, 0.340 mJ/mm2, 2000 shots.

Impaired Cerebrovascular Autoregulation in Large Vessel Occlusive Stroke after Successful Mechanical Thrombectomy: A Prospective Cohort Study
Introduction: Successful thrombectomy improves morbidity and mortality after stroke. The present prospective, observational cohort study investigated a potential correlation between the successful restoration of tissue perfusion by mechanical thrombectomy and intact cerebrovascular autoregulation (CA). Objective: Status of CA in patients with large vessel occlusive stroke after thrombectomy. Methods: After thrombectomy CA was measured using transcranial Doppler ultrasound. For this purpose a moving correlation index (Mxa) based on spontaneous arterial blood pressure fluctuations and corresponding cerebral blood flow veloci...

Ultrasound and magnetic resonance findings and correlation in hemiplegic patients with shoulder pain.
Conclusion: Although US is recommended as the first method in determining shoulder pathologies in hemiplegic patients, we suggest that MRI should be used as the first choice in hemiplegic patients with shoulder pain. MRI and US findings were not consistent, and US is dependent on the experience of the operator. MRI should be the first choice in cases where the diagnosis will affect the treatment choice due to the lack of correlation between US and MRI findings. PMID: 24722039 [PubMed - in process]
