Characteristics and outcomes of cerebral venous thrombosis associated with COVID-19.

Introduction: Previous reports and meta-analyses derived from small case series reported a mortality rate of up to 40% in patients with coronavirus disease 2019 associated cerebral venous thrombosis (COVID-CVT). We assessed the clinical characteristics and outcomes in an international cohort of patients with COVID-CVT.

Patients And Methods: This was a registry study of consecutive COVID-CVT patients diagnosed between March 2020 and March 2023.

Delayed onset Bickerstaff brainstem encephalitis overlapping Miller-Fisher Syndrome during SARS-CoV-2 infection.

Bickerstaff brainstem encephalitis (BBE) is a neuroimmunologic disease characterized by the acute onset of external ophthalmoplegia, ataxia, and consciousness disturbance, mostly subsequent to an infection. BBE is considered to be a variant of Miller-Fisher syndrome (MFS), which also exhibits external ophthalmoplegia and ataxia but not presenting consciousness alterations. Therefore, these two medical conditions are included in the clinical spectrum of the "Fisher-Bickerstaff syndrome" ( Shahrizaila and Yuki in J Neurol Neurosurg Psychiatry 84(5):576-583) [1].

Clinical and Diagnostic Findings of Acute Macular Neuroretinopathy and Paracentral Acute Middle Maculopathy in the COVID-19 Era.

Background: Growing evidence suggests an association between the infection from the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and eye disorders. The aim of this review was to analyze the clinical presentation and diagnostic features of acute macular neuroretinopathy (AMN) and paracentral acute middle maculopathy (PAMM) associated with COVID-19 infection. The features are then compared with previous reports regarding these retinal disorders, to recognize possible specific characteristics and to assess the role of multimodal ophthalmic imaging.

A case of febrile infection-related epilepsy syndrome (FIRES) in young adult: still a diagnostic and therapeutic challenge.

A new onset of status epilepticus in a previously healthy adult preceded by a recent minor febrile infection represents a diagnostic and therapeutic challenge in clinical practice. Considering the broad spectrum of epileptic encephalopathies caused by autoimmune mechanisms, differential diagnosis for new-onset refractory status epilepticus (NORSE) should include febrile infection-related epilepsy syndrome (FIRES), in order to not underestimate the underlying etiological condition triggering epilepsy in non-epileptic patients (Hon et al. in Recent Pat Inflamm Allergy Drug Discov 12:128-135, 2018).
