BACKGROUND: Kikuchi necrotizing lymphadenitis (KNL) is a rare and benign cause of lymphadenopathy, most often cervical. The etiology of KNL remains unknown. Central nervous system (CNS) involvement, such as in meningoencephalitis, is a very rare clinical manifestation of KNL, especially in children. CASE REPORTS: A 12-year-old boy presented with unilateral cervical lymphadenopathy and fever. Histopathological findings led to the diagnosis of KNL. He revisited due to severe headache and vomiting one week later...

Most acute central nervous system (CNS) viral infections lead to either encephalitis or meningitis. Many neurotropic viruses may cause CNS dysfunctions through various mechanisms including oxidative stress. Serum uric acid (SUA) levels, which are associated with oxidative stress and antioxidant status, are reduced in patients with various neurological disorders, including multiple sclerosis. We investigated the possible correlation between SUA levels and clinical disease status in patients with acute CNS viral infections...

BACKGROUND: Kawasaki disease (KD) is a type of systemic vasculitis of unknown etiology. Atypical Kawasaki disease is defined as that where there are signs and symptoms not corresponding to the classical criteria for this nosological entity. Children with atypical Kawasaki disease may present with acute abdominal symptoms, meningeal irritation, pneumonia or renal failure. CLINICAL CASES: We describe 4 children with ages ranging from 2 to 12 years who had atypical Kawasaki disease, with neurological and gastrointestinal symptoms as part of the systemic presentation of the disease...

Communicating hydrocephalus may complicate infantile bacterial meningitis, typically presenting with systemic features of infection. We report a rare case of 'subclinical meningoventriculitis' causing obstructive hydrocephalus and its challenging management. A healthy 10-week-old immunocompetent male patient presented with failure to thrive and vomiting, secondary to presumed gastro-oesophageal reflux. The child was neurologically alert, afebrile with normal inflammatory markers. Progressive macrocephaly prompted an MRI confirming triventricular hydrocephalus secondary to aqueductal stenosis...

BACKGROUND: Haemophilus influenzae type b (Hib) is an important cause of invasive bacterial disease in children worldwide. The limited awareness of disease burden is a major barrier to the introduction of Hib vaccine into China's National Immunization Program. Therefore, we conducted a systematic review and meta-analysis to estimate carriage of Hib and burden of its related diseases in Chinese children. METHODS: We systematically searched Pubmed, Web of Science, Ovid, Chinese National Knowledge Infrastructure (CNKI), and Wanfang databases for studies published up to December 31, 2016, reporting Hib carriage and burden of Hib diseases among children in Mainland China...

A large number of viruses belonging to various families are able to cause central nervous system (CNS) infections and contribute significantly to burden of disease in humans globally. Most viral CNS infections are benign and self-limiting, and most remain undiagnosed. However, some viruses can cause severe inflammation, leading to morbidity and mortality, and result in severe long-term residual damage and neurologic dysfunction in patients. The potential of viruses to cause CNS inflammation greatly varies depending on host factors, such as age, sex, and genetic background, as well as viral factors...

Type B coxsackievirus (CVB) is a common cause of acute and chronic myocarditis, meningitis and pancreatitis, often leading to heart failure and pancreatic deficiency. The polarization of CD4+ T lymphocytes and their cytokine milieu are key factors in the outcome of CVB-induced diseases. Thus, sensing the virus and driving the adaptive immune response are essential for the establishment of a protective immune response. TLR3 is a crucial virus recognition receptor that confers the host with resistance to CVB infection...

At present, the great attention is given to the neurospecific markers as their elevated level in the cerebrospinal fluid corresponds to the degree of destruction of relevant CNS cells. Therefore, actual direction of the studies of the pathogenesis and diagnosis of CNS diseases is to determine levels of neurospecific markers in the cerebrospinal fluid (CSF). The purpose of the study was to evaluate the diagnostic and prognostic role of NSE, S-100 protein, GFAP and MBP levels in CSF of patients with acute bacterial meningitis...

REVIEW
Katharina Maria Busl
Infectious complications in the neurointensive care unit (neuro-ICU) are common, including pneumonia, urinary tract infection, bloodstream infection, and intracranial infection. The neuro-ICU population poses a specific challenge in the diagnosis of infections, because of the high incidence of fever in acutely brain-injured patients. Furthermore, susceptibility to infections is likely enhanced by brain-injury (induced immune modulation). This article reviews the concept of brain injury-induced immune modulation, and summarizes available data and knowledge on nosocomial meningitis and ventriculitis, and systemic infectious complications in patients with traumatic brain injury, ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage, and status epilepticus...

The aim of this study was to report a minor outbreak of enterovirus A71 (EV-A71) infection in Poland and characterize isolates from cases of severe neurological infection detected in 2013 and 2016. Phylogenetic analysis revealed that Polish strains belonged to the C genogroup: C1, C2, and C4. Severe neurological manifestations as encephalitis or acute flaccid paralysis (AFP), were associated with all detected subgenogroups. The C2 subgenogroup was associated with the outbreak in Gdansk, with serious cases of AFP, myelitis, cerebellitis, encephalitis, but also with mild, sporadic cases of aseptic meningitis, in other Polish cities...

Leptospiroses are worldwide spread zoonoses caused by hydrophilic bacteria of the genus Leptospira. Humans can be infected by contact with an infected animal or indirectly via staying in a contaminated environment (water, wet soil), in natural foci, while working outdoors, or while doing outdoor sport and leisure activities. Leptospirosis may manifest as a mild flu-like illness or in a severe febrile form (meningitis, pulmonary haemorrhage, hepato-renal syndrome, or myocarditis). Presented are the laboratory diagnostic methods for leptospiroses with their advantages and disadvantages...

Localized magnetic fields (MFs) could easily penetrate the scalp, skull, and meninges, thus inducing an electrical current in both the central and peripheral nervous systems, which is primarily used in transcranial magnetic stimulation (TMS) for inducing specific effects on different regions or cells that play roles in various brain activities. Studies of repetitive transcranial magnetic stimulation (rTMS) have led to novel attractive therapeutic approaches. Neural stem cells (NSCs) in adult human brain are able to self-renew and possess multidifferential ability to maintain homeostasis and repair damage after acute central nervous system...

Acute bacterial meningitis is a severe infectious disease of the central nervous system. Its incidence decreases but lethality and sequelae remain high. The early initiation of appropriate treatment is a factor strongly determining the patient´s prognosis. The authors submit the Czech national guideline for diagnosis and treatment of community-acquired acute bacterial meningitis which has to provide clear and simple recommendations for clinicans involved in the care of meningitis in adults and children. The national guideline was based on the European guideline published in 2016 and adapted for the situation in the Czech Republic...
