PURPOSE: To describe the clinical pattern of viral central nervous system (CNS) infections and compare meningitis and encephalitis. METHODS: This is a retrospective study reporting the clinical characteristics and outcome of 138 cases of viral meningitis and meningoencephalitis in a real life experience at a referral centre in Turin, Northern Italy. RESULTS: Enteroviruses were predominant in younger patients who were mainly presenting with signs of meningitis, had shorter hospital admission and absence of complications, whereas herpesviruses had more often signs of encephalitis, were more frequent in elderly patients, had longer hospital admission and frequent complications and sequelae...

The aim of the study was to describe the clinical and epidemiological characteristics of the central nervous system (CNS) infection by varicella zoster virus (VZV) in patients older than 65 years in a tertiary community hospital. We retrospectively analysed the results of cerebrospinal fluid (CSF) testing in patients older than 65 years between 2007 and 2014 with clinically suspected VZV infection with CNS involvement. Patients whose CSF samples were positive for VZV DNA were included, as were those with negative results who simultaneously presented herpes zoster and CSF or magnetic resonance imaging findings suggestive of CNS infection, and in whom other possible aetiologies had been ruled out...

Since they were identified in 1975, human astroviruses have been considered one of the most important agents of viral acute gastroenteritis in children. However, highly divergent astroviruses infecting humans have been recently discovered and associated with extra-intestinal infections. The report of cases of fatal meningitis and encephalitis, especially in immunocompromised individuals, has broadened their disease spectrum. Although zoonotic transmission among animal and human astroviruses has not been clearly recognized, the genetic similarity between some human and animal viruses makes it likely to occur...

Spontaneous acute subarachnoid hemorrhage (SAH) from lumbar ependymoma in children is rare. We report a case of a14-year-old boy who developed sudden radicular low back pain while playing baseball. He was initially managed conservatively in a local hospital for suspected lumbar disc herniation, but later developed meningeal symptoms and fever before being referred to our hospital. There he underwent a diagnostic lumbar puncture in the emergency room; his cerebrospinal fluid suggested an SAH. Physical examination showed meningeal signs and cauda equina features...

BACKGROUND: Several enterovirus (EV) genotypes can result in aseptic meningitis, but their routes of access to the central nervous system remain to be elucidated and may differ between the pediatric and adult populations. OBJECTIVE: To assess the pattern of viral shedding in pediatric and adult subjects with acute EV meningitis and to generate EV surveillance data for Switzerland. STUDY DESIGN: All pediatric and adult subjects admitted to the University Hospitals of Geneva with a diagnosis of EV meningitis between 2013 and 2015 were enrolled...

Prompt antiretroviral therapy (ART) initiation after AIDS diagnosis, in the absence of certain opportunistic infections such as tuberculosis and cryptococcal meningitis, delays disease progression and death, but system barriers to inpatient ART initiation at large hospitals in the era of modern ART have been less studied. We reviewed hospitalizations for persons newly diagnosed with AIDS at Grady Memorial Hospital in Atlanta, Georgia in 2011 and 2012. Individual- and system-level variables were collected. Logistic regression models were used to estimate the odds ratios (ORs) for ART initiation prior to discharge...

BACKGROUND Myocarditis, defined as inflammation of myocardial tissue of the heart, is an uncommon cardiac presentation and is due to a variety of causes. It affects 1% of the US population, 50% of which is caused by coxsackie B virus. Cardiac tissue is the prime target, and destruction of myocardium results in cardiac failure with fluid overload. CASE REPORT Our patient was a 57-year-old woman with fever, headache, neck pain, and generalized malaise. Her white blood cell count was 13×10³ cells/mm³. Interestingly, lumbar puncture ruled out meningitis...

In the past century, advances in antibiotics and vaccination have dramatically altered the incidence and clinical outcomes of bacterial meningitis. We review the shifting epidemiology of meningitis in children, including after the implementation of vaccines that target common meningitic pathogens and the introduction of intrapartum antibiotic prophylaxis offered to mothers colonized with Streptococcus agalactiae. We also discuss what is currently known about the pathogenesis of meningitis. Recent studies of the human microbiome have illustrated dynamic relationships of bacterial and viral populations with the host, which may potentiate the risk of bacterial meningitis...

Accurate diagnosis of bacterial meningitis (BM) relies on cerebrospinal fluid (CSF) Gram stain and bacterial culture, which often present high false-negative rates because of the antibiotic abuse. Thus a novel and reliable diagnostic biomarker is highly required. Procalcitonin (PCT) is well demonstrated to be specifically produced from peripheral tissues by bacterial infection, which makes it a potential candidate. Here, we performed a prospective clinical study comprising a total of 143 patients to investigate the diagnostic value of CSF PCT, serum PCT and other conventional biomarkers for BM...

An 11-d-old Holstein bull calf was presented to the Veterinary Medical Teaching Hospital at the University of Wisconsin-Madison because of a 4-d history of diarrhea and persistent low-grade fever. Initial diagnosis was enteritis caused by Cryptosporidium and rotavirus. During hospitalization, the calf became stuporous and was only responsive to noxious stimuli, with hypotonia of all 4 limbs, tail, head, and neck. A cerebrospinal fluid analysis revealed xanthochromia, with marked lymphocytic pleocytosis, which was suggestive of viral meningitis and/or encephalitis...

Zika virus (ZIKV), chikungunya virus (CHIKV), and dengue virus (DENV) have been associated with clinical presentations that involve acute neurological complaints. In the current study, we identified ZIKV, CHIKV, and DENV in cerebrospinal fluid (CSF) samples from patients admitted to the Hospital Luis Vernaza (Guayaquil, Ecuador) to the Emergency Room or the Intensive Care Unit, with neurological symptoms and/or concern for acute arboviral infections. Viral RNA from one or more virus was detected in 12/16 patients...

Hand, foot and mouth disease (HFMD) is a highly contagious viral infection affecting young children during the spring to fall seasons. Recently, serious outbreaks of HFMD were reported frequently in the Asia-Pacific region, including China and Korea. The symptoms of HFMD are usually mild, comprising fever, loss of appetite, and a rash with blisters, which do not need specific treatment. However, there are uncommon neurological or cardiac complications such as meningitis and acute flaccid paralysis that can be fatal...

BACKGROUND: Transfusion-transmitted West Nile virus (WNV) infection is infrequent as a result of minipool (MP) and individual-donation (ID) nucleic acid testing (NAT) of blood donations. ID-NAT is triggered on the basis of local WNV activity identified by MP-NAT. STUDY DESIGN AND METHODS: A 78-year-old male patient who was treated for cardiac disease received 14 blood components from 30 donors in August 2016. He was discharged 7 days after aortic valve replacement and coronary bypass surgery, but was re-admitted on Day 12 with symptoms of viral infection, and eventually was diagnosed with aseptic meningitis...

Viral meningitis by non-polio enteroviruses (NPEV) is a major public health burden causing fatal outcomes especially in the younger population. Strong evidence exists that the blood-cerebrospinal-fluid (CSF) barrier (BCSFB) serves as an entry point for enterovirus and leucocytes into the central nervous system (CNS). Moreover, analysis of clinical CSF specimens of patients with a NPEV infection revealed a predominance of polymorphonuclear granulocytes (PMN) in the early phase and mononuclear cells in the later course of meningitis...

PURPOSE OF REVIEW: The purpose of this review is to give an overview of viral meningitis and then focus in on some of the areas of uncertainty in diagnostics, treatment and outcome. RECENT FINDINGS: Bacterial meningitis has been declining in incidence over recent years. Over a similar time period molecular diagnostics have increasingly been used. Because of both of these developments viral meningitis is becoming relatively more important. However, there are still many unanswered questions...

Viral infections of the central nervous system (CNS) range in clinical severity, with the most severe proving fatal within a matter of days. Some of the more than 100 different viruses known to affect the brain and spinal cord are neurotropic with a predilection for producing CNS infection. The host response to viral infection of the CNS is responsible for the pathophysiology and imaging findings seen in affected patients. Viral CNS infections can take the form of meningitis, encephalitis, encephalomyelitis, or, when involving the spinal cord and nerve roots, encephalomyeloradiculitis...

In humans, the herpes virus family member cytomegalovirus (CMV) is the most prevalent mediator of intrauterine infection-induced congenital defect. Central nervous system (CNS) dysfunction is a distinguishing symptom of CMV infection, and characterized by ventriculoencephalitis and microglial nodular encephalitis. Reports on the initial distribution of CMV particles and its receptors on the blood brain barrier (BBB) are rare. Nevertheless, several factors are suggested to affect CMV etiology. Viral particle size is the primary factor in determining the pattern of CNS infections, followed by the expression of integrin β1 in endothelial cells, pericytes, meninges, choroid plexus, and neural stem progenitor cells (NSPCs), which are the primary targets of CMV infection...

Enteroviruses (EVs) are associated with a broad spectrum of clinical presentation, including aseptic meningitis (AM), encephalitis, hand, foot and mouth disease, acute flaccid paralysis and acute flaccid myelitis. Epidemics occur sporadically and are associated with increased cases of AM in children. The present study describes the seroepidemiological analysis of circulating EVs in Ireland from 2005-2014 and phylogenetic characterisation of echovirus 30 (E-30), enterovirus A71 (EV-A71) and enterovirus D68 (EV-D68)...
