EEG electrode localization with 3D iPhone scanning using point-cloud electrode selection (PC-ES).

Electroencephalography source imaging (ESI) is a valuable tool in clinical evaluation for epilepsy patients but is underutilized in part due to sensitivity to anatomical modeling errors. Accurate localization of scalp electrodes is instrumental to ESI, but existing localization devices are expensive and not portable. As a result, electrode localization challenges further impede access to ESI, particularly in inpatient and intensive care settings.

Global Impact of the COVID-19 Pandemic on Stroke Volumes and Cerebrovascular Events: A 1-Year Follow-up.

Background And Objectives: Declines in stroke admission, IV thrombolysis (IVT), and mechanical thrombectomy volumes were reported during the first wave of the COVID-19 pandemic. There is a paucity of data on the longer-term effect of the pandemic on stroke volumes over the course of a year and through the second wave of the pandemic. We sought to measure the effect of the COVID-19 pandemic on the volumes of stroke admissions, intracranial hemorrhage (ICH), IVT, and mechanical thrombectomy over a 1-year period at the onset of the pandemic (March 1, 2020, to February 28, 2021) compared with the immediately preceding year (March 1, 2019, to February 29, 2020).

Carotid endarterectomy should not be based on consensus statement duplex velocity criteria.

Objective: Randomized trials support carotid endarterectomy (CEA) in asymptomatic patients with ≥60% internal carotid artery (ICA) stenosis. The widely referenced Society for Radiologists in Ultrasound Consensus Statement on carotid duplex ultrasound (CDUS) imaging indicates that an ICA peak systolic velocity (PSV) ≥230 cm/s corresponds to a ≥70% ICA stenosis, leading to the potential conclusion that asymptomatic patients with an ICA PSV ≥230 cm/s would benefit from CEA. Our goal was to determine the natural history stroke risk of asymptomatic patients who might have undergone CEA based on consensus statement PSV of ≥230 cm/s but instead were treated medically based on more conservative CDUS imaging criteria.

Risk of stroke after chiropractic spinal manipulation in medicare B beneficiaries aged 66 to 99 years with neck pain.

Objective: The purpose of this study was to quantify risk of stroke after chiropractic spinal manipulation, as compared to evaluation by a primary care physician, for Medicare beneficiaries aged 66 to 99 years with neck pain.

Methods: This is a retrospective cohort analysis of a 100% sample of annualized Medicare claims data on 1 157 475 beneficiaries aged 66 to 99 years with an office visit to either a chiropractor or primary care physician for neck pain. We compared hazard of vertebrobasilar stroke and any stroke at 7 and 30 days after office visit using a Cox proportional hazards model.

Interhospital helicopter transport for stroke.

Introduction: The safety, cost efficacy, and time-to-treatment benefit of air transport of stroke patients have been acknowledged. We describe stroke patients transported to our facility by helicopter emergency medical services (HEMS) from a large rural area and compare 2 consecutive 3-year periods.

Methods: A retrospective chart review was conducted of all patients transferred by HEMS to our facility over 6 years.

Critical care of patients with acute ischemic and hemorrhagic stroke: update on recent evidence and international guidelines.

Patients with acute ischemic and hemorrhagic stroke are often managed in a critical care setting. Disturbances in BP, body temperature, and serum glucose are commonly observed but their management remains controversial. The reversal of antithrombotic medications and prognostication are especially challenging for intracerebral hemorrhages.

A fatal case of postpartum cerebral angiopathy with literature review.

Introduction: Postpartum cerebral angiopathy (PCA) is a rare and pathophysiologically ill-characterized cerebral vasoconstriction syndrome, occurring within 30 days of a usually uncomplicated pregnancy and delivery. Its onset has been associated with the use of vasoactive medications, particularly ergot alkaloids. Other cases have occurred in the absence of these medications, prompting conjecture into possible overlap between PCA and other conditions known to cause cerebral vasoconstriction, including primary angiitis of the central nervous system and postpartum eclampsia.

"Triple-H" therapy for cerebral vasospasm following subarachnoid hemorrhage.

The combination of induced hypertension, hypervolemia, and hemodilution (triple-H therapy) is often utilized to prevent and treat cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH). Although this paradigm has gained widespread acceptance over the past 20 years, the efficacy of triple-H therapy and its precise role in the management of the acute phase of SAH remains uncertain. In addition, triple-H therapy may carry significant medical morbidity, including pulmonary edema, myocardial ischemia, hyponatremia, renal medullary washout, indwelling catheter-related complications, cerebral hemorrhage, and cerebral edema.
