Isolated amnesia is an uncommon presenting complaint in the pediatric age group. We report the case of an 18-year-old woman who presented with the acute onset of memory difficulty and an otherwise normal neurologic examination. Brain magnetic resonance imaging demonstrated inflammation in the bilateral temporal lobes. Serum and cerebrospinal fluid testing ultimately revealed a diagnosis of autoimmune encephalitis. Although rare, the acute onset of isolated amnesia deserves a prompt, comprehensive evaluation...

Antibody-mediated encephalopathies associated with serum or cerebrospinal fluid antibodies directed against neuronal structures may present with a multitude of neuropsychiatric syndromes. Although some of the antibody-driven conditions are now well recognized in adults (eg, N-methyl-D-aspartate receptor antibody encephalitis), the spectrum of neuropsychiatric manifestations in the pediatric population is less clear. Psychosis, confusion, catatonia, and additional behavioral changes, along with seizures, encephalopathy, and movement disorders, may be initial manifestations or concurrent features in all age groups...

Toxoplasmosis is one of the most important causes of foodborne illnesses and inflammatory complications, as well as congenital disorders. Promiscuous Toxoplasma is transmitted by contaminated food and animal produce, water, vegetations, fruits and sexually through semen. Toxoplasma infects nucleated cells with a unique tropism for muscles and central nervous system and a mind bugging malicious effect. Pregnant women with acute or reactivated toxoplasmosis can transmit Toxoplasma via transplacental to the fetus...

Human Herpes Virus 6 (HHV-6) reactivation occurs in approximately half of patients following allogeneic hematopoietic stem cell transplant (HSCT). While encephalitis and delayed engraftment are well-documented complications of HHV-6 following HSCT, the extent to which HHV-6 viremia causes disease in children is controversial. We performed a retrospective review of HHV-6 reactivation and possible manifestations in pediatric allogeneic HSCT patients at a single institution. Of 89 children and young adults who underwent allogeneic HSCT over a three-and-a-half-year period, 34 patients reactivated HHV-6 early post-transplant...

OBJECTIVE: Anti-N-methyl-d-aspartate receptor encephalitis (a-NMDARe) is an acute or subacute encephalopathy where electroencephalogram (EEG) is frequently obtained as part of the workup. Although no diagnostic EEG finding has been described so far, the definition of specific or typical patterns might help to distinguish this group among various encephalopathies of childhood. We examined EEG recordings of our patients with a-NMDARe in order to describe the most frequent findings. METHODS: Clinical and laboratory data and digital EEG recordings of 12 pediatric patients diagnosed with a-NMDARe in two major child neurology centers are evaluated...

Primary varicella zoster virus (VZV) infection, predominantly in the pediatric population, presents with pyrexia and a classic pruritic vesicular rash. In adults, although less common, it is more severe and linked to more complications. Neurological complications, which account for less than 1% of all VZV complications, include meningitis, encephalitis, arterial vasculopathy, and venous thrombosis. We present a case of a 39-year-old male who developed extensive cerebral venous sinus thrombosis following primary VZV infection...

BACKGROUND: Acute central nervous system (ACNS) infections such as meningitis, encephalitis and cerebellitis still cause morbidity and mortality among children. The aim of this study was to verify whether neuropsychological impairment may develop in ACNS survivors. METHODS: The study included pediatric patients affected by ACNS disorders, aged 3-16 years admitted to the Bambino Gesù Children Hospital, Rome from June 2013 till June 2015. The patients and their parents underwent a psychological interview and neuropsychological tests during the first week of hospital admission and 1 year after, during a follow-up control...

PURPOSE: This study aimed to investigate whether serum neuron-specific enolase (NSE) was expressed in acute encephalitis syndrome (AES) that causes neuronal damage in children. METHODS: This prospective observational study was conducted in the pediatric neurology ward of Soetomo Hospital. Cases of AES with ages ranging from 1 month to 12 years were included. Cases that were categorized as simple and complex febrile seizures constituted the non-AES group. Blood was collected for the measurement of NSE within 24 hours of hemodynamic stabilization...

Acanthamoeba encephalitis is a rare, often fatal condition, particularly after HSCT, with 9 reported cases to date in the world literature. Our case was originally diagnosed with ALL at age 3 years, and after several relapses underwent HSCT at age 9 years. At 17 years of age, he was diagnosed with secondary AML for which he underwent a second allogeneic HSCT. He presented with acute-onset worsening neurological deficits on day +226 after the second transplant and a post-mortem diagnosis of Acanthamoeba encephalitis was established, with the aid of the CDC...

BACKGROUND: Clinical syndromes associated with West Nile virus (WNV) infection range from fever to neuroinvasive disease. Understanding WNV epidemiology and disease history is important for guiding patient care and healthcare decision-making. The objective of this review was to characterize the existing body of peer-reviewed and surveillance literature on WNV syndromes and summarize epidemiologic and clinical parameters. METHODS: We followed scoping review methodology described by the Joanna Briggs Institute...

Anti-N-methyl-D-aspartate (NMDA) encephalitis is a disorder characterized by acute neuro-psychiatric symptoms, appearing mostly after a recent febrile disease, with a gradual progressive course, associated with laboratory or radiologic evidence of active inflammation. Many of the patients will present with a continuous neuro-cognitive disorder which could lead to major morbidity and even mortality. It was recently reported that this disorder can present at childhood as a primary disease or as a secondary complication of herpes simplex infection...

PURPOSE: Although influenza primarily affects the respiratory system, in some cases, it can cause severe neurological complications. Younger children are especially at risk. Pediatric literature is limited on the diagnosis, treatment, and prognosis of influenza-related neurological complications. The aim of the study was to evaluate children who suffered severe neurological manifestation as a result of seasonal influenza infection. METHODS: The medical records of 14 patients from six hospitals in different regions of the country were evaluated...

OBJECTIVE: To investigate the pathological features of fatal pediatric hand foot and mouth disease (HFMD). METHODS: The histopathological features of HFMD were first summarized from literature, and then confirmed by in-house autopsies. Furthermore, immunohistochemistry was conducted to detect the distribution and expression level of two enterovirus 71 (EV71) receptors scavenger receptor class B, member 2 (SCARB2), and P-selectin glycoprotein ligand-1 (PSGL1) in the samples of autopsies...

REVIEW

Myelin oligodendrocyte glycoprotein (MOG), a member of the immunoglobulin (Ig) superfamily, is a myelin protein solely expressed at the outermost surface of myelin sheaths and oligodendrocyte membranes. This makes MOG a potential target of cellular and humoral immune responses in inflammatory demyelinating diseases. Due to its late postnatal developmental expression, MOG is an important marker for oligodendrocyte maturation. Discovered about 30 years ago, it is one of the best-studied autoantigens for experimental autoimmune models for multiple sclerosis (MS)...

BACKGROUND: La Crosse Virus (LACV) is a primary cause of pediatric viral encephalitis in the USA and can result in severe clinical outcomes. Almost all cases of LACV encephalitis occur in children 16 years or younger, indicating an age-related susceptibility. This susceptibility is recapitulated in a mouse model where weanling (3 weeks old or younger) mice are susceptible to LACV-induced disease, and adults (greater than 6 weeks) are resistant. Disease in mice and humans is associated with infiltrating leukocytes to the CNS...

BACKGROUND: Chandipura virus (CHPV) is a leading cause of acute encephalitis with high mortality in paediatric population in India. A micro-neutralization ELISA (MN-ELISA) assay was developed for the detection of neutralizing antibodies (Nab) against CHPV. This novel method gives read-out in the form of ELISA optical density (OD) values and has a shorter turn-around time (TAT) as compared to the conventional cytopathic effect (CPE)-based neutralization assay (MN-CPE). The assay was developed using an Indian strain of CHPV...
