Heterogeneity in the evaluation of suspected MIS-C: a cross-sectional vignette-based survey.

Background And Objectives: Multisystem Inflammatory Syndrome in Children (MIS-C) is an emerging complication of COVID-19 which lacks a definitive diagnostic test and evidence-based guidelines for workup. We sought to assess practitioners' preferences when initiating a workup for pediatric patients presenting with symptoms concerning for MIS-C.

Methods: In a cross-sectional vignette-based survey, providers were presented with clinical vignettes of a patient presenting with 24 h of fever from a community with high rates of COVID-19.

Good outcome with early empiric treatment of neural larva migrans due to Baylisascaris procyonis.

We report a remarkably good outcome in a 14-month-old boy with early clinical diagnosis and aggressive empirical treatment of neural larva migrans caused by the raccoon roundworm Baylisascaris procyonis. He presented with fever, meningismus, lethargy, irritability and asymmetric spastic extremity weakness. Early findings of marked blood and cerebrospinal fluid eosinophilia and of diffuse white matter signal abnormality in the brain and spinal cord on MRI suggested a parasitic encephalomyelitis.

Spinal cord involvement in a child with raccoon roundworm (Baylisascaris procyonis) meningoencephalitis.

A 14-month-old previously healthy boy developed progressively worsening neurological symptoms secondary to eosinophilic meningoencephalitis with myelitis caused by raccoon roundworm (Baylisascaris procyonis) infection. MRI demonstrated T2 hyperintensity and enhancement of the cerebral white matter, cerebellum and spinal cord. Prior case reports have described signal abnormality within the brains of patients with raccoon roundworm neural larva migrans (NLM).
