BACKGROUND: A lumbar lipomyelocele is a closed spinal dysraphism that can cause tethered cord syndrome. Between 5-15% of spinal dysraphism surgery cases are burdened with complications, the most common being wound infections or dehiscence and cerebrospinal fluid leak. Acute communicating hydrocephalus has never been described as a complication of this type of surgery. CASE DESCRIPTION: A 6-year-old girl, who had undergone several surgeries in another Institution for lumbar lipomyeloschisis, came to our attention for a second opinion about the management of her spinal dysraphism...

BACKGROUND: Tick-borne encephalitis (TBE) is a clinically variable but potentially severe Flavivirus infection, with the outcome strongly dependent on secondary immunopathology. Neutrophils are present in cerebrospinal fluid (CSF) of TBE patients, but their pathogenetic role remains unknown. In animal models, neutrophils contributed both to the Flavivirus entry into central nervous system (CNS) and to the control of the encephalitis, which we attempted to evaluate in human TBE. METHODS: We analyzed records of 240 patients with TBE presenting as meningitis (n = 110), meningoencephalitis (n = 114) or meningoencephalomyelitis (n = 16) assessing CSF neutrophil count on admission and at follow-up 2 weeks later, and their associations with other laboratory and clinical parameters...

BACKGROUND: Powassan virus (POWV) is a tick-borne flavivirus that causes rare, but often severe, disease in humans. POWV neuroinvasive disease was added to the U.S. nationally notifiable disease list in 2001 and nonneuroinvasive disease was added in 2004. The only previous review of the epidemiology of POWV disease in the United States based on cases reported to the Centers for Disease Control and Prevention (CDC) covered the period from 1999 through 2005. METHODS: We describe the epidemiology and clinical features of laboratory-confirmed POWV disease cases reported to CDC from 2006 through 2016...

Oropouche virus (OROV) is the unique known human pathogen belonging to serogroup Simbu of Orthobunyavirus genus and Bunyaviridae family. OROV is transmitted by wild mosquitoes species to sloths, rodents, monkeys and birds in sylvatic environment, and by midges (Culicoides paraensis and Culex quinquefasciatus) to man causing explosive outbreaks in urban locations. OROV infection causes dengue fever-like symptoms and in few cases, can cause clinical symptoms of aseptic meningitis. OROV contains a tripartite negative RNA genome encapsidated by the viral nucleocapsid protein (NP), which is essential for viral genome encapsidation, transcription and replication...

Acute meningitis can be the first manifestation of an underlying systemic inflammatory disorder (SID). In the current study, we aimed to identify clinical indicators for SIDs in patients admitted for acute aseptic meningitis. All patients hospitalised for acute aseptic meningitis over a 4-year period in a department of internal medicine were included retrospectively. Patients with neoplastic meningitis were excluded. Extraneurological signs were recorded using a systematic panel. Systemic inflammatory disorder diagnosis was made according to current international criteria...

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...

Headache is an uncommon symptom in Guillain-Barré syndrome (GBS). We review four clinical settings related to GBS in which headache may be present. We focus on pathophysiological explanations, alerting the clinician to further potential investigations and treatment. Most reports of headache in GBS occur in the context of the posterior reversible encephalopathy syndrome, an increasingly recognized dysautonomia-related GBS complication. Less frequent is headache in the setting of increased intracranial pressure and papilledema (secondary intracranial hypertension), Miller Fisher syndrome, and cerebral venous sinus thrombosis...

This study aimed to quantitatively assess and compare the effect and safety of posterior fossa decompression with duraplasty (PFDD) and posterior fossa decompression (PFD) in treating patients with Chiari malformation type I (CM1). PubMed, Embase, and Cochrane Library were searched through May 2017. Fourteen cohort studies, involving a total of 3666 patients with CM1, were included. Studies were pooled, and the relative risk (RR) and its corresponding 95% confidence interval (CI) were calculated. The decrease in syringomyelia was better for patients in the PFDD group than for patients in the PFD group (RR=1...

BACKGROUND: Echovirus 6 (E6), is one of the main enteroviral serotypes, was initially isolated from patients with aseptic meningitis (AM) and is a major cause of hospitalization among children and adults worldwide. METHODS: A cerebrospinal fluid (CSF) sample was collected from patient with clinically suspected aseptic meningitis (AM) in August 2011. Following detection of a virus and subsequent virus serotyping, the whole genome sequence was determined. The sequence of the VP1 region of the isolated strain E6 RA/E6/Ahvaz/Iran/2011 showed 79% (>75%) nucleotide and 94% (>85%) amino acid homology with prototype strain D'Amori...

Despite the availability of nucleic acid amplification tests (NAATs), most of aseptic acute meningitides, encephalitides, and meningoencephalitides (AAMEMs) in adults remain of unknown etiology so far. To shed light on such topic, we aimed to evaluate potential predictors for AAMEMs of unknown origin. We collected retrospectively data from all consecutive cases of AAMEMs in adults discharged from an Italian referral hospital, from January 2004 to December 2016. Laboratory analysis included common immunometric methods and NAATs...

Enterovirus A71 (EV-A71), coxsackievirus A16 (CV-A16), and CV-A6 are the major causative agents of Hand-foot-and-mouth disease (HFMD). These viruses belong to the species Enterovirus A of the genus Enterovirus of the family Picornaviridae. These viruses can also cause aseptic meningitis (AM), encephalitis and/or paralysis. EV-A71 is one of the main infectious agents related to severe encephalitis. Between 1997 and 2013, East and Southeast Asia experienced large encephalitis outbreaks caused by EV-A71 infections, which ranged from severe to lethal...

We reviewed the epidemiological and clinical characteristics of 927 aseptic meningitis patients in Shandong in 2014, and the phylogeny of predominant enterovirus (EV) types causing this disease was analyzed. A total of 209 patients that were positive for EV were identified by both cell culture and a reverse transcription-seminested PCR in cerebrospinal fluid samples. The positive patients were most likely to be children within 15 years of age, had symptoms such as fever, vomiting and nausea (P< .05). The 209 EV sequences belonged to 11 types, and coxsackievirus B5, echovirus types 6 and 30 were predominant types...

PURPOSE OF REVIEW: Immune checkpoint inhibitors represent a major step forward in the field of oncologic immunotherapy these last years and have significantly increased survival of cancer patients in an ever-growing number of indications. These agents block specific immune checkpoint molecules (programmed cell death protein 1 and its ligand as well as cytotoxic T-lymphocyte-associated antigen 4) that normally downregulate the immune response. These new agents show a specific range of adverse effects induced by abnormal immunologic activation...
