Enterovirus 71 (EV71) is a single-strand RNA virus that causes hand, foot and mouth disease (HFMD) in infants and young children, leading to neurological complications with significant morbidity and mortality. Unfortunately, the pathogenesis of EV71 infection is not well understood. In this study, we investigated the IL-17F rs1889570 and rs4715290 gene polymorphisms in a Chinese Han population. Severe cases and cases with EV71 encephalitis had a significantly higher frequency of the rs1889570 T/T genotype and T allele...

Early establishment of infectious process allows for expedited clinical management of meningitis and encephalitis. The FilmArray Meningitis/Encephalitis (FA-M/E) panel provides rapid detection of potential pathogens associated with encephalitis/meningitis in both immunocompetent and compromised patients. Here we conducted a one year review of the performance of the FA-M/E panel at a tertiary care children's hospital. 265 samples from 251 patients were tested. 87.25% (219/251) were negative, 9.96% (25/251) were positive for viral analytes and 3...

Neurological manifestations associated with HHV-7 have been described in primary infection in children, and very occasionally in immunocompromised adult patients. However, the role of HHV-7 reactivation as a cause of central nervous system (CNS) diseases in immunocompetent adults has not yet been defined. We retrospectively analyzed clinical and microbiological features of adults with neurological symptoms who underwent lumbar puncture and a multiplex polymerase chain reaction (PCR) for herpesviruses (HHV-1-8) and enteroviruses performed in cerebrospinal fluid (CSF), during a 4-year period...

Enterovirus A71 (EV-A71) infection has grown to become a serious threat to global public health. It is one of the major causes of hand, foot, and mouth disease (HFMD) in infants and young children. EV-A71 can also infect the central nervous system (CNS) and induce diverse neurological complications, such as brainstem encephalitis, aseptic meningitis, and acute flaccid paralysis, or even death. Viral proteins play a crucial role in EV-A71 infection. Many recent studies have discussed the structure and function of EV-A71 proteins, and the findings reported will definitely aid the development of vaccines and therapeutic approaches...

Empirical knowledge suggests that acute neurologic disorders are common in sub-Saharan Africa, but studies examining the true burden of these diseases in children are scarce. We performed this prospective, observational study to evaluate the prevalence, clinical characteristics, treatment approaches, and outcomes of children suffering acute neurologic illness or injury (ANI) in an urban and rural site in the Democratic Republic of the Congo. Over 12 months, 471 out of 6,563 children admitted met diagnostic criteria for ANI, giving a hospital-based prevalence of 72/1,000 admissions...

Studies of cerebrospinal fluid (CSF) γδ T cells in children are limited, especially due to the lack of control data. In adults, gamma/delta T cells (TCR-γδ) residing in the intrathecal space are sometimes involved in neuroinflammation. To evaluate the possible role of γδ T cells in pediatric neuroinflammation, we immunophenotyped CSF and blood lymphocytes using flow cytometry in a case-control study of 100 children with non-inflammatory neurologic disorders (NIND), 312 with opsoclonus-myoclonus (OMS), and 23 with other inflammatory neurologic disorders (OIND)...

BACKGROUND: The necessity of lumbar puncture for the differentiation of central nervous system (CNS) infection in children with febrile status epilepticus (FSE) remains controversial. The aim of the present study is to investigate the diagnostic necessity of lumbar puncture for children with FSE after the introduction of bacterial conjugate vaccines into the infant immunization program. METHODS: Our retrospective cohort study was performed in children aged 6 to 60 months who were admitted to the pediatric ward at Kitakyushu General Hospital from January 1, 2011 to December 31, 2015 for seizures with fever...

Bickerstaff's brainstem encephalitis (BBE) is a rare immune-mediated disorder characterized by ophthalmoplegia, ataxia and disturbance of consciousness, which may overlap with Guillain-Barré syndrome (GBS) if there is additional limb weakness. We report a 7-month-old boy presented with ophthalmoplegia followed by a rapidly ascending paralysis of all four limbs and disturbance of consciousness. The initial impression was BBE with overlapping GBS. This was supported by sequential nerve conduction study (NCS) findings compatible with an acute inflammatory demyelinating polyneuropathy (AIDP)...

N-methyl-D-aspartate receptor (NMDAR) encephalitis is the most common autoimmune encephalitis due to autoantibodies against neuronal surface antigens, can affect both children and adults, leading to neurological and neuropsychological sequelae. However, it is potentially treatable and the prompt start of immunotherapy associates with better prognosis. Conversely, misdiagnosis can be harmful. The detection of NMDAR antibodies in serum and cerebrospinal fluid plays a pivotal role in the diagnostic work-up. Reliable methods for NMDAR antibody detection are thus fundamental to assure accurate diagnosis and allow early treatments...

Enterovirus 71 (EV71) is a major pathogen that causes hand, foot and mouth disease (HFMD) as well as neurological complications, such as encephalitis. The chemokines involved in the migration of leukocytes have increasingly been implicated in infectious diseases of the central nervous system. Few studies have evaluated the levels of chemokines in HMFD children with EV71-related encephalitis. In the present study, we evaluated the cerebrospinal fluid (CSF) levels of the chemokines IL-8, RANTES, MIG, MCP-1 and IP-10 in 99 children with EV71-related encephalitis and 22 children with febrile convulsion (FC)...
