Amantadine as an Aid to Extubation in Severe Acute Brain Injury: A Case Series.

For a subset of patients with severe acute brain injury (SABI) undergoing invasive mechanical ventilation, the primary barrier to successful extubation is depressed mental status. Amantadine is a neurostimulant that has been demonstrated to increase arousal and improve functional outcomes in patients with SABI. In this case series, we describe 5 patients with SABI and invasive mechanical ventilation who received amantadine as an agent to improve mental status to allow extubation.

Trends and predictors of decompressive craniectomy in acute ischemic stroke, 2011-2020.

Introduction: Rates of decompressive craniectomy (DC) in acute ischemic stroke (AIS) have been reported to decline over time, attributed to an increase in endovascular therapy (EVT) preventing the development of malignant cerebral edema. We sought to characterize trends in DC in AIS between 2011 and 2020.

Material And Methods: We performed a retrospective observational study of U.

Spontaneous Hypothermia As an Indicator of Early Diffuse Anoxic Brain Injury in Post-Cardiac Arrest Patients.

Objectives: To determine the association between spontaneous hypothermia (SH), defined as initial post-resuscitation core body temperature less than 34°C, and diffuse anoxic brain injury (DABI) on initial CT scan of the head (CTH) in post-cardiac arrest patients.

Design Setting And Participants: This was a retrospective, observational cohort study. This study was performed at the University of Rochester Medical Center Strong Memorial Hospital.

Association of Do-Not-Resuscitate orders and in-hospital mortality among patients undergoing cranial neurosurgery.

Background: Previous studies identified pre-existing DNR orders as a predictor of mortality after surgery. We sought to evaluate mortality of patients receiving cranial neurosurgery with DNR orders placed at the time of, or within 24 h of admission.

Methods: We performed a retrospective cohort study using the California State Inpatient Database, January 2018 to December 2020.

Hospital Discharge and Readmissions Before and During the COVID-19 Pandemic for California Acute Stroke Inpatients.

Background: Acute stroke therapy and rehabilitation declined during the COVID-19 pandemic. We characterized changes in acute stroke disposition and readmissions during the pandemic.

Methods: We used the California State Inpatient Database in this retrospective observational study of ischemic and hemorrhagic stroke.

Reversal of Advanced Directives in Neurologic Emergencies.

Objective: Patients with advanced directives or Medical Orders for Life-Sustaining Treatment (MOLST), including "Do Not Resuscitate" (DNR) and/or "Do Not Intubate" (DNI), may be candidates for procedural interventions when presenting with acute neurologic emergencies. Such interventions may limit morbidity and mortality, but typically they require MOLST reversal. We investigated outcomes of patients with MOLST reversal for treatment of neurologic emergencies.

Safer Stroke-Dx Instrument: Identifying Stroke Misdiagnosis in the Emergency Department.

Background: Missed or delayed diagnosis of acute stroke, or false-negative stroke (FNS), at initial emergency department (ED) presentation occurs in ≈9% of confirmed stroke patients. Failure to rapidly diagnose stroke can preclude time-sensitive treatments, resulting in higher risks of severe sequelae and disability. In this study, we developed and tested a modified version of a structured medical record review tool, the Safer Dx Instrument, to identify FNS in a subgroup of hospitalized patients with stroke to gain insight into sources of ED stroke misdiagnosis.

A Novel COL4A2 Mutation Associated with Recurrent Strokes.

Mutations in type four collagens, specifically COL4A1 and COL4A2, have been associated with cerebral small vessel disease (SVD), defined as lacunar infarcts, deep intracerebral hemorrhages (ICH), and leukoaraiosis. We present a case of a man with recurrent cerebral infarcts, related to a novel COL4A2 mutation, the p.A1534S variant.

Assessing diagnostic error in cerebral venous thrombosis via detailed chart review.

Background Diagnostic error in cerebral venous thrombosis (CVT) has been understudied despite the harm associated with misdiagnosis of other cerebrovascular diseases as well as the known challenges of evaluating non-specific neurological symptoms in clinical practice. Methods We conducted a retrospective cohort study of CVT patients hospitalized at a single center. Two independent reviewers used a medical record review tool, the Safer Dx Instrument, to identify diagnostic errors.

Bifrontal Biparietal Cruciate Decompressive Craniectomy in Pediatric Traumatic Brain Injury.

Background: We investigated a novel surgical approach to decompressive craniectomy (DC), the bifrontal biparietal, or "cruciate," craniectomy, in severe pediatric traumatic brain injury (TBI). Cruciate DC was designed with a fundamentally different approach to intracranial pressure (ICP) control compared to traditional DC. Cruciate DC involves craniectomies in all 4 skull quadrants.

A Systematic Review of the Efficacy of Levetiracetam in Neonatal Seizures.

Objective: Seizures are the most common neurological complication in neonatal intensive care units. Phenobarbital (PB) remains the first-line antiepileptic drug (AED) for neonatal seizures despite known neurotoxicity. Levetiracetam (LEV) is a newer AED not approved for neonates.

Hemostasis in endoscopic endonasal skull base surgery using the Aquamantys bipolar sealer: Technical note.

Background: A major challenge during endoscopic transsphenoidal surgery is adequate intraoperative hemostasis. The Aquamantys® is a relatively new bipolar sealing device which uses radiofrequency energy and saline. This promotes hemostasis while decreasing charring and thermal spread.
