OBJECTIVE: This article discusses the clinical manifestations and management of infectious peripheral neuropathies. LATEST DEVELOPMENTS: Several infectious etiologies of peripheral neuropathy are well-recognized and their treatments are firmly established. The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is associated with several central and peripheral nervous system manifestations, including peripheral neuropathies...

Progressive multifocal leukoencephalopathy (PML), a viral infection of the central nervous system (CNS), is most commonly associated with advanced HIV infection. Although the severe neurological conditions - PML and progressive multifocal leukoencephalopathy immune reconstitution inflammatory syndrome (PML-IRIS) - are linked to HIV, little is known about their characteristics in the era of established antiretroviral therapy (ART). The aim of this systematic review, which was performed by adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines, was to determine the prognosis of PML in patients with HIV...

BACKGROUND: Infections are discussed as risk factor for multiple sclerosis (MS) development and relapses. This may lead to decreased vaccination frequency in newly diagnosed patients. OBJECTIVE: The aim of this study was to evaluate the relation of MS diagnosis to subsequent vaccination frequency. METHODS: Based on German ambulatory claims data from 2005 to 2019, regression models were used to assess the relation of MS diagnosis ( n = 12,270) to vaccination...

Recent advances in Nanotechnology have revolutionized the production of materials for biomedical applications. Nowadays, there is a plethora of nanomaterials with potential for use towards improvement of human health. On the other hand, very little is known about how these materials interact with biological systems, especially at the nanoscale level, mainly because of the lack of specific methods to probe these interactions. In this review, we will analytically describe the journey of nanoparticles (NPs) through the brain, starting from the very first moment upon injection...

Patients with Lyme neuroborreliosis (LNB) are rarely tested for the presence of neurovirulent viruses other than tick-borne encephalitis virus (TBEV); however, such coinfections could be of clinical importance. The aim of the study was to search for the presence of neurotropic viruses in a LNB patients. Fourteen patients admitted with signs and symptoms of neuroinfection who were eventually diagnosed to have LNB (according to the guidelines of the European Federation of Neurological Societies) were subjects of the study...

Pneumocephalus, or air entrapment within the cranium, is a rare but dangerous condition with a variety of causes, including trauma, surgery, or predisposing infection. Trauma is the most common etiology, as fractures provide easy access for air to become entrapped in the cranium. However, access such as via the central nervous system with leak exists. Though not as common as traumatic pneumocephalus, pneumocephalus secondary to infection is a dangerous condition. The literature is sparse on this example of ear-nose-throat infection, making it difficult to form and ascertain guidelines for the management of infectious pneumocephalus and its complications...

Cryptococcal meningitis is a severe fungal infection that primarily affects individuals with compromised immune systems, such as those with the human immunodeficiency virus (HIV) or those undergoing immunosuppressive therapies after organ transplantation. In rare cases, immunocompetent individuals may also be affected by this life-threatening condition. We present the case of a 64-year-old male patient with no known underlying immune deficiency diagnosed with cryptococcal meningitis, who presented with persistent headaches and subjective fevers...

INTRODUCTION: Fusariosis of the central nervous system (CNS) is extremely uncommon. Treatment and outcome data from previously published cases may provide some guidance in light of the ongoing fungal meningitis outbreak in 2023 involving Fusarium spp. in the United States and Mexico. METHODS: We reviewed the published literature describing cases of invasive fusariosis of the (CNS) that included data on patient demographic characteristics, treatment, and outcome...

INTRODUCTION: The incidence of community-acquired acute bacterial meningitis has decreased during the last decades. However, outcome remains poor with a significant proportion of patients not surviving and up to 50% of survivors suffering from long-term sequelae. These guidelines were developed by the Deutsche Gesellschaft für Neurologie (DGN) under guidance of the Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF) to guide physicians through diagnostics and treatment of adult patients with acute bacterial meningitis...

INTRODUCTION: Vancomycin dosing tailored for newborns is challenging due to the significant influence of maturation and organ function on pharmacokinetics. Population pharmacokinetic (popPK) models can be used to improve target attainment in neonates. OBJECTIVES: The primary objective was to derive and evaluate a popPK model of intravenous vancomycin for neonates. Secondly, the predictive performance of this popPK model was compared with published popPK models. METHODS: This is a retrospective cohort study of neonates admitted to the neonatal intensive care unit receiving intravenous vancomycin...

BACKGROUND: Rhinocerebral mucormycosis (RCM) is a rare, fatal, invasive fungal infection infecting mainly patients with immunocompromised conditions, such as diabetes mellitus, hematologic malignancies, and organ transplantations. Coronavirus disease 2019 (COVID-19) disease in these patients further weakens the immune system due to several factors, including hypoxia, corticosteroid usage (further increasing hyperglycemic status), mechanical ventilation, increased serum ferritin levels, endothelitis due to free radicals, and glucose receptor protein upregulation...

OBJECTIVES: The objectives of this study were to study the spectrum of neurological complications in children with lymphoreticular malignancy (acute lymphoblastic leukemia, Hodgkin, and non-Hodgkin lymphoma) at diagnosis and during treatment and to determine the etiology of these complications. MATERIALS AND METHODS: In this descriptive cohort study, conducted between November 2018 and March 2020, 204 children with a diagnosis of lymphoreticular malignancy were enrolled...

BACKGROUND: The neurological complications of coronavirus disease 2019 (COVID-19) infection and the side effects of vaccination include immune-mediated diseases of the central nervous system (CNS) such as acute disseminated encephalomyelitis (ADEM). It is an acute-onset demyelinating disease that involves a rapid evolution and multifocal neurological deficits that develops following a viral or bacterial infection or, less frequently, following vaccination. Acute hemorrhagic leukoencephalitis (AHLE) is the hemorrhagic variant of ADEM that presents a more severe evolution which can be followed by coma and death...

BACKGROUND: This research synthesized scientific evidence on the use of pharmacotherapy as intervention to reduce cognitive impairments in adult patients with primary central nervous system (CNS) infections. METHODS: We searched for experimental studies published in English prior to October 2021 in MEDLINE, Embase and Cochrane databases. We included non-randomized studies (NRS) and randomized control trials (RCT) of pharmacotherapy versus placebo, drug, or a combination of drugs in adults with primary CNS infection...

OBJECTIVE: To date, there is no consensus on the surgery strategies of cranioplasty (CP) and ventriculoperitoneal shunt (VPS) placement. This meta-analysis aimed to investigate the safety of staged and simultaneous operation in patients with comorbid cranial defects with hydrocephalus to inform future surgery protocols. METHODS: A meta-analysis of PubMed, Ovid, Web of Science, and Cochrane Library databases from the inception dates to February 8, 2023 adherent to PRISMA guidelines was conducted...

BACKGROUND: The ratio of cerebrospinal fluid (CSF) to peripheral blood glucose at the same period is an important index for diagnosing and monitoring the efficacy of central nervous system infection, especially bacterial meningitis. Some guidelines refer that blood glucose measurement should be carried out before lumbar puncture. The main reason is to avoid possible effect of stress response induced by lumbar puncture on the level of blood glucose. However, there is no consensus on whether it should be followed in actual clinical work, since up to now no research work having been published on whether lumbar puncture will induce the changes on blood glucose...

Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system, characterized by chronic, inflammatory, demyelinating, and neurodegenerative processes. MS management relies on disease-modifying drugs that suppress/modulate the immune system. Cladribine tablets (CladT) have been approved by different health authorities for patients with various forms of relapsing MS. The drug has been demonstrated to deplete CD4+ and CD8+ T-cells, with a higher effect described in the former, and to decrease total CD19+ , CD20+ , and naive B-cell counts...

INTRODUCTION: Multiple sclerosis (MS) is an autoimmune disease affecting the central nervous system. Monoclonal antibodies (mAbs) have shown efficacy in reducing MS relapse rates, disease progression, and brain lesion activity. AREAS COVERED: This article reviews the literature on the use of mAbs for the treatment of MS, including their mechanisms of action, clinical trial data, safety profiles, and long-term outcomes. The review focuses on the three main categories of mAbs used in MS: alemtuzumab, natalizumab, and anti-CD20 drugs...

INTRODUCTION: Infections of the central nervous system are a considerable basis of mortality in people living with HIV, with progression to cryptococcal meningitis documented at around 15% of HIV-associated mortality globally, with nearly three-quarters occurring in the sub-Saharan Africa. Discoveries from previous studies prelude to the mortality of cryptococcal antigen positive, which persisted to be elevated than in cryptococcal antigen negative persons. One feasible interpretation of this could be due to undiagnosed cryptococcus...

BACKGROUND: With the new highly active drugs available for people with multiple sclerosis (pwMS), vaccination becomes an essential part of the risk management strategy. OBJECTIVE: To develop a European evidence-based consensus for the vaccination strategy of pwMS who are candidates for disease-modifying therapies (DMTs). METHODS: This work was conducted by a multidisciplinary working group using formal consensus methodology. Clinical questions (defined as population, interventions, and outcomes) considered all authorized DMTs and vaccines...
