CT Angiography in Evaluating Large-Vessel Occlusion in Acute Anterior Circulation Ischemic Stroke: Factors Associated with Diagnostic Error in Clinical Practice

Fellows’ Journal Club This study included 520 consecutive patients with a clinical diagnosis of acute ischemic stroke (49.4% men; mean age, 72 years) who underwent CTA to evaluate large-vessel occlusion of the proximal anterior circulation. CTA scans were retrospectively reviewed by a consensus panel of 2 neuroradiologists. The prevalence of large-vessel occlusion was 16% (84/520 patients); 20% (17/84) of large-vessel occlusions were missed atthe initial CTA evaluation. In multivariate analysis, non-neuroradiologists were more likely to miss large-vessel occlusion compared with neuroradiologists, and occlusions of the M2 segment were more likely to be missed compared with occlusions of the distal internal carotid artery and/or M1 segment. Calcified emboli were present in 4 of 17 (24%) initially missed or misinterpreted large-vessel occlusions. Abstract A 70-year-old male patient with acute ischemic stroke. At initial CTA evaluation, LVO due to a calcified embolus in the M2 seg

Nanodevices for the brain could thwart formation of Alzheimer’s plaques

Experts warn against malarial drugs as a cure for coronavirus

Researchers warn early encouraging signals from small-scale preliminary trials for the use of hydroxychloroquine to treat coronavirus should be taken with caution. Current evidence suggests chloroquine and hydroxychloroquine can not be used as a general treatment for all COVID-19 infections. Researchers say the medications should be restricted for the treatment of COVID-19 patients with pneumonia and high death risk, and only then as part of a clinical trial. The study also points out the negative side effects produced by the anti-malarial drugs and warns that those who need the medication to treat Lupus might not have access to treatment if widespread use for coronavirus occurs. The study reports there is no evidence to support the mass use of chloroquine or hydroxychloroquine to prevent infection from occurring. from Neuroscience News https://ift.tt/2KPYQoJ

COVID-19 study shows that men have over double the death rate of women

Males who contract COVID-19 have 2.5 times the death rate of women. Being males is a significant risk factor for worse disease severity, regardless of age. Researchers found a similar trend in data from the 2003 SARS outbreak. The study speculates the reason why males are more prone to negative outcomes of coronavirus is due to levels of ACE2, which is significantly higher in males than females. from Neuroscience News https://ift.tt/2Skuizp

A Comprehensive Review of Brain Connectomics and Imaging to Improve Deep Brain Stimulation Outcomes

Congratulations Drs. Wong, Almedia, Hess and Okun on the publication of “A Comprehensive Review of Brain Connectomics and Imaging to Improve Deep Brain Stimulation Outcomes,” in Movement Disorders. Abstract DBS is an effective neuromodulatory therapy that has been applied in various conditions, including PD, essential tremor, dystonia, Tourette syndrome, and other movement disorders. There have also been recent examples of applications in epilepsy, chronic pain, and neuropsychiatric conditions. Innovations in neuroimaging technology have been driving connectomics, an emerging whole‐brain network approach to neuroscience. Two rising techniques are functional connectivity profiling and structural connectivity profiling. Functional connectivity profiling explores the operational relationships between multiple regions of the brain with respect to time and stimuli. Structural connectivity profiling approximates physical connections between different brain regions through reconstruction o

Teaching Video NeuroImages: Useful bedside testing for myasthenia gravis: The phenomenon of enhanced ptosis

During examination of a 62-year-old woman with a diagnosis of myasthenia gravis, left eyelid manual elevation caused exacerbated ptosis on the right (enhanced ptosis) (figure). According to Hering law, there is approximately equal innervation of the levator palpebrae superioris muscles in both eyelids. 1 In an asymmetric ptosis, the motor impulses increase to compensate ptosis on the more affected side but also flow to the contralateral eyelid, which mitigates ptosis on that side. With manual elevation of the more affected eyelid, the need to sustain eyelid elevation is relieved, and there is an attenuation of these motor impulses causing ptosis enhancement of the other eyelid (video 1). 2 from Neurology recent issues https://ift.tt/3eZkVij

Patterns of common coronavirus infections could aid understanding of COVID-19

Examining different types of coronaviruses, researchers report the viral infections coexist in most winter seasons, although they exhibit structured seasonal patterns with some appearing to generate illnesses in the community at the same time. Others appear to circulate in their own unique patterns. Findings suggest SARS-CoV-2, the virus responsible for COVID-19, may find itself in competition with other seasonal coronaviruses and either struggle to persist in the longterm or may eliminate one or more seasonal coronavirus. from Neuroscience News https://ift.tt/2y3SdMI

Neurologic Complications in COVID-19 Patients: Signal or Noise?

The medical community continues to wrestle with the full implications of the COVID-19 pandemic. Data is surfacing daily based on the experiences of physicians working on the frontlines. Now we must sort out this information to develop a more complete understanding of what it means. We also need to figure out how – or if – it should change the approach to caring for patients infected by the novel coronavirus. This is certainly true for neurologists as case information trickles in about neurologic signs and symptoms. A recent case report in JAMA outlined the clinical course of an elderly patient with COVID-19 who developed encephalopathy. The authors of the paper mentioned other potential neurologic complications of the disease, including acute stroke, impaired consciousness, and skeletal muscle injury. Another case study published in The Lancet on April 1 reports the first known presentation of Guillain-Barré syndrome in a patient with COVID-19. Other reports include trigeminal neu

The cutting-edge applications of ultrasound in neurology

Imaging is central to neurological practice. It doesn’t take much to tempt a neurologist to ‘order’ or ‘request’ an MRI or a CT . In appropriate circumstances the imaging is a DAT scan , and with a bit more savvy, exciting imaging modalities such as amyloid scans and tau PET scans . In the playpen of the neurologist, the more ‘high tech’ the imaging technology, the more cutting-edge it feels-even if it doesn’t make much of a difference to the patient. Ultrasound on the other hand is the mongrel of imaging technologies. Too simple, too cheap, too available, too unsophisticated-not better than good old  X-rays . It is safe to assume that the pen of the neurologist hardly ever ticks the ultrasound box. What for? prd brain scan.
