A 73-year-old man presented with three episodes of dysphasia and disinhibited behaviour, a single seizure and transient ischaemic attack-like events characterised by right arm and/or leg weakness. These episodes were separated by month-long asymptomatic intervals. Medical history included rheumatoid arthritis, which was clinically quiescent on leflunomide.Repeated cerebrospinal fluid examination showed a persistent lymphocytosis with mildly reduced glucose and elevated protein; oligoclonal bands and viral PCR were negative...

Pseudoexfoliation syndrome is an age-related systemic disease that mainly affects the anterior structures of the eye. Despite a worldwide distribution, reported incidence and prevalence of this syndrome vary widely between ethnicities and geographical areas. The exfoliative material is composed mainly of abnormal cross-linked fibrils that accumulate progressively in some organs such as the heart, blood vessels, lungs or meninges, and particularly in the anterior structures of the eye. The exact pathophysiological process still remains unclear but the association of genetic and environmental factors are thought to play a role in the development and progressive extracellular accumulation of exfoliative material...

Most flying-spot optical coherence tomography and optical coherence microscopy (OCM) systems use a symmetric confocal geometry, where the detection path retraces the illumination path starting from and ending with the spatial mode of a single-mode optical fiber. Here we describe a visible light OCM instrument that breaks this symmetry to improve transverse resolution without sacrificing collection efficiency in scattering tissue. This was achieved by overfilling a water immersion objective on the illumination path while maintaining a conventional Gaussian mode detection path (1/e2 intensity diameter ∼0...

An approximately 10-year-old, female Congo African grey parrot ( Psittacus erithacus erithacus) developed progressive, unilateral exophthalmos and buphthalmos. Survey radiographs revealed a large, coelomic, soft tissue mass, which was confirmed on computed tomography scan. Aspirates of both the contents of the buphthalmic globe and coelomic mass were consistent with Cryptococcus species. Initial results were later confirmed with serum antigen latex agglutination and polymerase chain reaction testing, and the organism was then identified as Cryptococcus neoformans with DNA sequencing...

Mouse hepatitis virus (MHV) infection causes meningoencephalitis by disrupting the neuro-glial and glial-pial homeostasis. Recent studies suggest that MHV infection alters gap junction protein connexin 43 (Cx43)-mediated intercellular communication in brain and primary cultured astrocytes. In addition to astrocytes, meningeal fibroblasts also express high levels of Cx43. Fibroblasts in the meninges together with the basal lamina and the astrocyte endfeet forms the glial limitans superficialis as part of the blood-brain barrier (BBB)...

Primary lymphomas of the central nervous system (PCNSL) are highly aggressive tumors affecting exclusively the CNS, meninges, and eyes. PCNSL must be separated from secondary spread of systemic lymphoma to the CNS (SCNSL), which may occur at diagnosis or relapse of systemic lymphomas. At present, there are no valid methods to distinguish PCNSL from SCNSL based on tumor biopsy because of similar histological presentation. However, SCNSL and PCNSL are different in terms of prognosis and adequate therapy protocols...

The epidemiological surveillance data for tuberculosis in Spain in 2015 is analysed in this report. This information was gathered through cases reported to the Red Nacional de Vigilancia Epidemiológica [National Epidemiological Surveillance Network]. In addition, the update of the treatment of the cases reported in 2014 is included. The incidence rate of tuberculosis in 2015 was 10.59 cases per 100,000 inhabitants, 10% less than in 2014. This decrease was mainly due to the sustained decreased trend of pulmonary tuberculosis rates, from other locations and in adults, while for cases of tuberculous meningitis and in children the decrease is less marked, with a tendency to stabilization...

Serogroup C invasive meningococcal disease (IMD) outbreaks in men who have sex with men (MSM) have been occurring with greater frequency in urban areas across the United States. An effective vaccine for IMD is available and is recommended for MSM in outbreak settings. Particular subgroups of MSM have been disproportionately represented in outbreaks, specifically young, Black, and HIV-positive MSM. As little is known about the knowledge, awareness, and vaccination status of young MSM, we sought to describe this and explore racial/ethnic differences...

Arthropod-borne viruses (arboviruses) are transmitted to humans primarily through the bites of infected mosquitoes and ticks. West Nile virus (WNV) is the leading cause of domestically acquired arboviral disease in the continental United States (1,2). Other arboviruses, including La Crosse, Powassan, Jamestown Canyon, St. Louis encephalitis, and eastern equine encephalitis viruses, cause sporadic cases of disease and occasional outbreaks. This report summarizes surveillance data reported to CDC for 2016 for nationally notifiable arboviruses...

Human enteroviruses (EVs) are the most common causative agents infecting human, causing many harmful diseases, such as hand, foot, and mouth disease (HFMD), herpangina (HA), myocarditis, encephalitis, and aseptic meningitis. EV-related diseases pose a serious worldwide threat to public health. To gain comprehensive insight into the seroepidemiology of major prevalent EVs in humans, we firstly performed a serological survey for neutralizing antibodies (nAbs) against Enterovirus A71 (EV-A71), Coxsackie virus A16 (CV-A16), Coxsackie virus A6 (CV-A6), Coxsackie virus A10 (CV-A10), Coxsackie virus B3 (CV-B3), Coxsackie virus B5 (CV-B5), Echovirus 25 (ECHO25), and Echovirus 30 (ECHO30) among the healthy population in Xiamen City in 2016, using micro-neutralization assay...

We report a case of vaccine-associated paralytic poliomyelitis (VAPP) in an immunocompromised patient with acute lymphocytic leukemia who was initially diagnosed with aseptic meningitis. Isolation of Sabin-like type 1 poliovirus from the patient's cerebrospinal fluid made this a case of vaccine-related poliovirus (VRPV) infection. The patient developed paralysis and respiratory distress and deceased a few months after onset of paralysis with respiratory failure. This tragic case report highlights the emergence of VAPP and indicates the importance of timely diagnosis of VRPV infections to improve clinical management of VRPV-infected patients and to prevent the devastating consequences of silent introduction of VRPVs in treatment wards and eventually in the society...

The high human immunodeficiency virus (HIV) prevalence in sub-Saharan Africa has markedly changed the epidemiology and presentation of adult meningitis. We conducted a systematic review using PubMed, Embase, Ovid, CENTRAL, and African Index Medicus to identify studies in Africa with data on neurological outcomes in adults after meningitis. We found 22 articles meeting inclusion criteria. From 4 studies with predominately pneumococcal meningitis, a median of 19% of survivors experienced hearing loss up to 40 days...

Congenital anomalies of the spine may occur with malformations of the central nervous, cardiovascular, gastrointestinal, respiratory, and genitourinary systems. This is a case of myelomeningocele with unilateral right renal agenesis in a newborn. The patient suffered complications of cerebrospinal fluid leak and meningitis, but was successfully treated and discharged on day 86. In this case, unilateral right renal agenesis represented a significant surgical risk because failure of the remaining kidney could result in renal failure...

We herein report a case of a 31-year-old Japanese man who simultaneously had a positive influenza A virus antigen test result and Vogt-Koyanagi-Harada disease (VKHD), demonstrated by both diffuse multiple early hyperfluorescent points on fluorescein fundus photography and serous retinal detachments on optical coherence tomography. He had meningitis. It was difficult to determine whether the main cause of meningitis was influenza A or VKHD. After initial treatment with peramivir for influenza A and then methylprednisolone pulse with subsequent corticosteroid therapy for VKHD, his symptoms improved gradually...

A 2-day-old infant presented with poor feeding and grunting. Investigations revealed a raised C reactive protein of 164. Full septic screen was done, which subsequently confirmed a diagnosis of group B streptococcus meningitis. Baby was apyrexial and haemodynamically stable. There were no obvious neurological manifestations, and a routine cranial ultrasound scan was done, which revealed echogenic changes in the basal ganglia and thalami. MRI brain showed extensive haemorrhagic infarction within the lentiform and caudate nuclei with involvement of both posterior limbs of the internal capsule...

Following a request by the Australian government, human remains of Australian origin were identified in the anatomical collection of Charité, the medical faculty of Berlin. We initiated an interdisciplinary provenance research on such remains to ensure their identity, elucidate their history, and prepare for a possible return to Australia. Here, we present results regarding a skull in the collection labeled as stemming from Tasmania. The non-invasive anthropological investigation revealed the skull to stem from a girl of about 15 years of age who most likely died of a massive otitis/petrositis with subsequent meningitis...
