Pediatric and Adult Brain Death/Death by Neurologic Criteria Consensus Guideline.

Background And Objectives: The purpose of this guideline is to update the 2010 American Academy of Neurology (AAN) brain death/death by neurologic criteria (BD/DNC) guideline for adults and the 2011 American Academy of Pediatrics, Child Neurology Society, and Society of Critical Care Medicine guideline for infants and children and to clarify the BD/DNC determination process by integrating guidance for adults and children into a single guideline. Updates in this guideline include guidance related to conducting the BD/DNC evaluation in the context of extracorporeal membrane oxygenation, targeted temperature management, and primary infratentorial injury.

Methods: A panel of experts from multiple medical societies developed BD/DNC recommendations.

Comparative effectiveness and complications of intravenous ceftriaxone compared with oral doxycycline in Lyme meningitis in children: a multicentre prospective cohort study.

Introduction: Lyme disease is the most common vectorborne disease in the Northern hemisphere with more than 400 000 new cases in the USA annually. Lyme meningitis is an uncommon but potentially serious clinical manifestation of Lyme disease. Intravenous ceftriaxone had been the first-line treatment for Lyme meningitis, but is associated with a high rate of complications.

Nervous System Lyme Disease-Facts and Fallacies.

The central or peripheral nervous systems may be involved in up to 15% of patients with untreated infection with B burgdorferi sensu lato, characteristic involvement including meningitis, cranial neuritis, and radiculoneuritis. Diagnosis, based on a logical combination of clinical context and antibody-based testing, is usually straightforward, as is treatment. Misconceptions about what does and does not constitute neurologic disease, and about laboratory testing in this infection, have resulted in widespread anxiety that a broad range of other disorders may be attributable to nervous system Lyme disease.

Lyme neuroborreliosis: known knowns, known unknowns.

Lyme borreliosis affects the nervous system in three principal ways-mononuclear cell meningitis, cranial neuropathies and radiculoneuropathies-the last a broad term encompassing painful radiculopathy, unifocal and multifocal peripheral nerve involvement. Diagnostic tools have been significantly refined-including improved peripheral blood and CSF serodiagnostics-and much has been learned about the interactions between the causative pathogen and the nervous system. Despite these advances in our understanding of this disease, a broad range of other disorders continue to be misattributed to nervous system Lyme borreliosis, supported by, at best, limited evidence.

Papilledema Secondary to Neurologic Lyme Borreliosis: A Meta-Case Series.

Background: Papilledema can be a manifestation of neurologic Lyme borreliosis (LB). The clinical manifestations and progression of these cases have not been comprehensively documented to date. We aimed to describe clinical and diagnostic features and to assess patient outcomes in cases of papilledema secondary to neurologic LB.

Clinical Practice Guidelines by the Infectious Diseases Society of America (IDSA), American Academy of Neurology (AAN), and American College of Rheumatology (ACR): 2020 Guidelines for the Prevention, Diagnosis and Treatment of Lyme Disease.

This evidence-based clinical practice guideline for the prevention, diagnosis, and treatment of Lyme disease was developed by a multidisciplinary panel representing the Infectious Diseases Society of America (IDSA), the American Academy of Neurology (AAN), and the American College of Rheumatology (ACR). The scope of this guideline includes prevention of Lyme disease, and the diagnosis and treatment of Lyme disease presenting as erythema migrans, Lyme disease complicated by neurologic, cardiac, and rheumatologic manifestations, Eurasian manifestations of Lyme disease, and Lyme disease complicated by coinfection with other tick-borne pathogens. This guideline does not include comprehensive recommendations for babesiosis and tick-borne rickettsial infections, which are published in separate guidelines.

Specificity and Diagnostic Utility of Cerebrospinal Fluid CXCL13 in Lyme Neuroborreliosis.

Background: Demonstration of intrathecal production of Borrelia-specific antibodies (ITAb) is considered the most specific diagnostic marker of Lyme neuroborreliosis (LNB). Limitations include delayed detectability in early infection and continued presence long after successful treatment. Markers of active inflammation-increased cerebrospinal fluid (CSF) leukocytes, protein, and CXCL13-provide nonspecific markers of active infection.

A Neurologist's View of Lyme Disease and Other Tick-Borne Infections.

Tick-borne infections-including tick-borne encephalitis viruses, represented in the United States by rare infections with Powassan and deer tick viruses, and more often Lyme disease-are of increasing importance to neurologists. Lyme neuroborreliosis (LNB) causes all or part of a triad including meningitis, radiculoneuritis, and cranial neuritis. Rarely, parenchymal brain and spinal cord involvement occur, with focal findings on examination and magnetic resonance imaging (MRI).

Lyme neuroborreliosis.

Purpose Of Review: To review the recent evidence clarifying the symptomatology and diagnosis of nervous system Lyme disease.

Recent Findings: Two-tier testing combining pairs of ELISAs, using C6 or VlsE assays to replace second tier Western blots, may eliminate confusion about test interpretation. Cerebrospinal fluid (CSF) can be informative in diagnosing central nervous system (CNS) Lyme disease, not peripheral nervous system (PNS) disorders.

Neuroborreliosis.

Neurologic manifestations of nervous system infection with Borrelia burgdorferi, Borrelia garinii, and Borrelia afzelii are qualitatively similar, and include lymphocytic meningitis, cranial neuritis, radiculoneuritis, and other focal or multifocal mononeuropathies. Parenchymal central nervous system (CNS) infection occurs rarely. Neurobehavioral changes are common, but are rarely evidence of CNS infection.

Neuroborreliosis and Neurosyphilis.

Purpose Of Review: This article presents an overview of the current diagnosis and management of two spirochetal infections of the nervous system, neuroborreliosis (Lyme disease) and neurosyphilis, focusing on similarities and differences. Although neuroborreliosis was first identified almost a century ago, much confusion remains about how to accurately diagnose this quite treatable nervous system infection. Well-established diagnostic tools and therapeutic regimens exist for neurosyphilis, which has been well-known for centuries.

Neuroimmunomodulators in Neuroborreliosis and Lyme Encephalopathy.

Background: Lyme encephalopathy, characterized by nonspecific neurobehavioral symptoms including mild cognitive difficulties, may occur in patients with systemic Lyme disease and is often mistakenly attributed to central nervous system (CNS) infection. Identical symptoms occur in many inflammatory states, possibly reflecting the effect of systemic immune mediators on the CNS.

Methods: Multiplex immunoassays were used to measure serum and cerebrospinal fluid (CSF) cytokines in patients with or without Lyme disease to determine if there are specific markers of active CNS infection (neuroborreliosis), or systemic inflammatory mediators associated with neurobehavioral syndromes.

Diagnosis and management of Lyme neuroborreliosis.

The nervous system is involved in 10-15% of patients infected with B. burgdorferi, B. afzelii and B.

Nervous System Abnormalities and Legionnaire's Disease.

Although patients with Legionnaire's disease frequently develop alterations of consciousness, this is no more frequent than in patients hospitalized with other, equally severe forms of bacterial pneumonia. Legionella meningitis occurs rarely, if ever. Patients with Legionnaire's are susceptible to critical illness polyneuropathy/myopathy, as are other critically ill patients.

Neuroborreliosis.

Appropriate, critical application of evidence-based diagnostic criteria enables both a clear definition of what constitutes neuroborreliosis-nervous system infection with Borrelia burgdorferi sensu stricto in the US, B garinii and less commonly B. afzelii and other species in Europe-and recognition that this disorder is quite similar in Europe and the US. Most commonly evidenced by lymphocytic meningitis and/or multifocal inflammation of the peripheral (common; cranial neuropathy, radiculopathy, mononeuropathy multiplex) or central (rare) nervous system, it is readily diagnosed and highly antibiotic responsive.

In-Transit Telemedicine Speeds Ischemic Stroke Treatment: Preliminary Results.

Background And Purpose: Time to treatment is critically important in ischemic stroke. We compared the efficacy and cost of teleneurology evaluation during patient transport with that of mobile stroke transport units.

Methods: Using cellular-connected telemedicine devices, we assessed 89 presumptive stroke patients in ambulances in transit.

Reducing Hospital-Acquired Infections Among the Neurologically Critically Ill.

Background: Hospital-acquired infections (HAIs) result in excess morbidity, mortality, and resource consumption. Immobilized, ventilator-dependent ICU patients are at the highest risk of HAI.

Methods: Despite broad implementation of relevant bundles, HAI incidence in our neuro ICU remained high, particularly catheter-associated urinary tract infections (CAUTIs) and ventilator-associated events (VAEs).
