Patients with ischemic stroke attributed to large- or small-vessel disease are not considered at high risk for atrial fibrillation (AF), and the AF incidence rate in this population is unknown.To determine whether long-term cardiac monitoring more effective than usual care detection patients through 12 months of follow-up.The STROKE-AF trial was a randomized (1:1), multicenter (33 sites US) clinical that enrolled 496 between April 2016 July 2019, primary end point follow-up August 2020....
Importance Recent large infarct thrombectomy trials used heterogeneous imaging modalities and time windows for patient selection. Noncontrast computed tomographic (CT) scan is the most common stroke approach. It remains uncertain whether effective patients with infarcts identified using noncontrast CT alone within 24 hours of onset. Objective To evaluate effect in a on Design, Setting, Participants Open-label, blinded–end point, bayesian-adaptive randomized trial interim analyses early...
The STROKE AF study found that in patients with prior ischemic stroke attributed to large-artery atherosclerotic disease (LAD) or small-vessel occlusive (SVD), 12% developed over 1 year when monitored an insertable cardiac monitor (ICM). occurrence subsequent years is unknown.
Many long-duration astronauts develop signs of elevated intracranial pressure and have neuro-ophthalmological findings similar to idiopathic hypertension (IIH) patients. Some also present with nasal congestion subjective olfactory impairment. We prospectively evaluated function in IIH patients the effect 6° head-down tilt, which simulates headward fluid shifting microgravity, as spaceflight analogues.Olfaction was tested for all subjects upright tilt positions using two different measures:...
The Stroke of Known Cause and Underlying Atrial Fibrillation (STROKE AF) trial found that approximately 1 in 8 patients with recent ischemic stroke attributed to large- or small-vessel disease had poststroke atrial fibrillation (AF) detected by an insertable cardiac monitor (ICM) at 12 months. Identifying predictors AF could be useful when considering ICM routine clinical care.To determine the association between commonly assessed risk factors detection new STROKE cohort monitored ICM.This...
The incidence of dementia is on the rise and expected to continue increase in foreseeable future. Two most common subtypes are Alzheimer's subtype vascular dementia. Hyperhomocysteinemia has been shown serve as a risk factor for due an associated blood-brain barrier dysfunction subsequent small-vessel disease pathology. There varying causes hyperhomocysteinemia, including genetic dietary, among others. We highlight importance identifying hyperhomocysteinemia potential etiologic therapeutic target
Neuromyelitis-optica is a relapsing inflammatory autoimmune condition characterized mainly by acute myelitis and optic neuritis although other criteria exist. IgG against AQP-4 receptor on the astrocyte foot processes 76% sensitive 100% Specific for Neuromyelitis-optica. Immunosuppression with Azathioprine 50% effective but never reported to worsen A 52-year-old-female history of blindness secondary bilateral Myasthenia gravis, in remission, underwent extensive work up remitting brain...
We report a case of 60-year-old right-handed woman with hypertension, hyperlipidemia, and hypothyroidism who presented three-week history recurrent thunderclap headaches accompanied by photophobia, phonophobia, nausea, vomiting. She reported one brief episode slurred speech, expressive aphasia, right facial droop, hemiparesis suggestive TIA. Family was remarkable for primary angiitis the CNS (PACNS) in mother. Neurologic examination unremarkable. CT head negative; angiography (CTA) neck...
OBJECTIVE: To determine whether dynamic changes in optic nerve head (ONH) structure, as measured by high definition optical coherence tomography (HD-OCT), occur immediately after lowering intracranial pressure (ICP). BACKGROUND: Biomechanical the ONH with sustained elevation ICP are well-established. However, time course of structural elevated has not been studied. It is known acute will cause measurable ONH. HD-OCT allows in-vivo enhanced depth imaging papillary sub-structures. ...
Non-arteritic anterior ischemic optic neuropathy (NAION) is characterized by sudden onset of painless visual loss with ipsilateral nerve edema. It estimated to affect 6000 Americans each year. The exact pathogenesis this condition not known but it currently thought that ischemia the disc may precipitate a compartment syndrome head (ONH) leading clinical features NAION. There have been several medication trials, which largely unsuccessful. Corticosteroids considered mainstay for treatment...
Acute lymphoblastic leukemia (ALL) is an unusual diagnosis in the adult population. These cases are rarely reported combination with ischemic stroke and endocarditis. We present a case of elderly female patient presenting acute hyperleukocytosis new ALL, border-zone nonbacterial thrombotic
