PURPOSE Diagnosis of WNV (WNV) relies upon serologic testing which may take several days after the onset of clinical symptoms to turn positive. Anecdotal reports suggest the presence of plasma cells or plasmacytoid lymphocytes in the cerebrospinal fluid (CSF) may be an early indicator of WNV infection. METHODS The CSFs of 89 patients (12 with WNV, 12 with other viral illness {OVI}, and 65 wit...

Scrub typhus, which is caused by Orientia tsutsugamushi, is a systemic illness that causes generalized vasculitis. The central nervous system (CNS) is the most crucial target in other rickettsial diseases; however, there have been several reports of encephalitis or meningitis without direct evidence of rickettsial invasion of the CNS in cases of scrub typhus. To investigate CNS involvement in c...

Introduction. Myelin oligodendrocyte glycoprotein antibody associated disorders (MOGAD) are immunemediated inflammatory conditions of the central nervous system (CNS) with a wide clinical phenotypic variability. In order to further understand possible phenotype MOGAD here we report pediatric case acute disseminated encephalomyelitis (ADEM) MOG antibodies. Case outline. A previously healthy four...

Multiple sclerosis is a common inflammatory disease of the CNS. A great number of immunologically active molecules have been identified in the CSF of these patients (CSF-MS), but the role of these substances in neuronal dysfunction, especially in the origin of transient symptoms, is unclear. Therefore, we investigated the effect of CSF from 13 multiple sclerosis patients on membrane currents of...

We report a case of Eikenella corrodens sepsis associated with CSF pleocytosis in a very low birth weight neonate. A 1000-gram male neonate was born at 27-week gestation due to preterm labor. The patient presented with signs and symptoms of sepsis and was treated for suspected meningitis with intravenous ampicillin and gentamicin for 7 days, with cefotaxime added for three weeks. He had a norma...

A 40-year-old man developed headache and a left oculomotor nerve palsy. MRI revealed diffuse enlargement of the pituitary gland and thickening of the pituitary stalk with strong gadolinium enhancement (figure). CSF examination showed a lymphocytic pleocytosis; there were laboratory findings of panhypopituitarism, but no related symptoms. We administered IV methylprednisolone. The headache and o...

BACKGROUND The seasonality, clinical and radiographic features and outcome of aseptic meningitis have been described for regional outbreaks but data from a wider geographic area is necessary to delineate the epidemiology of this condition. METHODS A retrospective chart review was completed of children presenting with aseptic meningitis to eight Canadian pediatric hospitals over a two-year per...

Abstract. A 17-year-old man who presented with progressive quadriparesis is reported. About 8 months prior to admission, he had miliary tuberculosis, and that improved with anti-tuberculous therapy. He had also developed tuberculous meningitis and tuberculous myelitis, respectively. He regularly took anti-tuberculous drugs until this illness. Neurological findings were compatible with cervical ...

Experimental allergic encephalomyelitis (EAE) was produced in six adult rhesus monkeys. The animals were evaluated serially by ocular, ophthalmoscopic, fluorescein fundus angiographic, pupillary, visual evoked potential, neurologic, cerebrospinal fluid (CSF), and hematologic examinations and by postmortem detailed histopathologic examination. All the animals developed acute EAE. Four of the mon...
