Bilateral papilledema with vision loss due to post-COVID-19-induced thiamine deficiency: illustrative case.

Background: Bilateral papilledema with vision loss is considered a neurosurgical emergency due to high intracranial pressure. However, it may not be the only cause of papilledema. The authors reported an association among coronavirus disease 2019 (COVID-19), bilateral papilledema, blindness, and Wernicke's encephalopathy (WE).

Cerebral venous sinus thrombosis complicated by subdural hematomas: Case series and literature review.

Background: Cerebral venous sinus thrombosis (CVST) can cause elevated intracranial pressure, hemorrhagic venous infarct, and cortical subarachnoid hemorrhage. We present a case series and literature review to illustrate that CVST can also present with subdural hematoma (SDH).

Case Description: Chart review was completed on a retrospective case series of CVST with spontaneous SDH.

Rapid Warfarin reversal in the setting of intracranial hemorrhage: a comparison of plasma, recombinant activated factor VII, and prothrombin complex concentrate.

Objective: To compare the safety and effectiveness of three methods of reversing coagulopathic effects of warfarin in patients with potentially life-threatening intracranial hemorrhage.

Methods: A retrospective electronic medical record review of 63 patients with warfarin-related intracranial hemorrhage between 2007 and 2010 in an integrated health care delivery system was conducted. The three methods of rapid warfarin reversal were fresh-frozen plasma (FFP), activated factor VII (FVIIa; NovoSevenRT [Novo Nordisk, Bagsværd, Denmark]), and prothrombin complex concentrate (PCC; BebulinVH [Baxter, Westlake Village, California, USA], ProfilnineSD [Grifols, North Carolina, USA]), each used adjunctively with vitamin K (Vit K, phytonadione).

Temperature management in acute neurologic disorders.

Temperature management in acute neurologic disorders has received considerable attention in the last 2 decades. Numerous trials of hypothermia have been performed in patients with head injury, stroke, and cardiac arrest. This article reviews the physiology of thermoregulation and mechanisms responsible for hyperpyrexia.
