BACKGROUND The epidemiology of human herpesvirus 6 (HHV-6) encephalitis after allogeneic hematopoietic cell transplantation (HCT) and its relationship with HHV-6 reactivation have not been sufficiently characterized. METHODS This prospective, multicenter study of 230 allogeneic HCT recipients investigated the epidemiology of HHV-6 reactivation and HHV-6 encephalitis. Plasma HHV-6 DNA load was...

We describe a 24-year-old woman with anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis that developed 3 weeks after normal delivery. She was treated with methylprednisolone, intravenous immunoglobulin, and plasmapheresis, in addition to teratoma excision. However, her recovery was slow, and dysmnesia and mental juvenility persisted even two years after onset. To date, five patients w...

The recent association of a fatal human case of encephalitis with a newly identified lyssavirus apparently acquired from a native Australian bat has highlighted the possibility that previous human infections have passed urecognised. Infected bats have been identified on the Queensland Gold Coast where extensive close contact between bats and humans has occurred for many years. In an attempt to ...

Although herpes simplex encephalitis is not classically considered an opportunistic infection, reactivation of herpes simplex is being seen increasingly in patients with cancer or immunosuppression. The authors present a patient with malignant glioma and HSV-1 encephalitis whose PCR-proven encephalitis recurred after temozolomide (TMZ) chemoradiation despite acyclovir therapy, and summarize det...

Anti-N-methyl-D-aspartate receptor (NMDA-R) encephalitis is a severe form of encephalitis that has been identified within the context of acute neuropsychiatric manifestations. We report the case of an 18-year-old adolescent referred for a first episode of acute psychosis. The clinical picture rapidly deteriorated to a state of catatonia, decreased consciousness and autonomic instability. Detect...

Since its original description in 2007, anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis associated with an ovarian teratoma is an increasingly recognized etiology of previously unexplained encephalopathy and encephalitis. Extreme delta brush (EDB) is a novel electroencephalogram (EEG) finding seen in many patients with anti-NMDAR encephalitis. The presence of this pattern is associ...

Tick-borne encephalitis (TBE) is a virus infection which sometimes causes human disease. The TBE virus is found in ticks and certain vertebrate tick hosts in restricted endemic localities termed TBE foci. The formation of natural foci is a combination of several factors: the vectors, a suitable and numerous enough number of hosts and in a habitat with suitable vegetation and climate. The presen...

Anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis, the most common type of autoimmune encephalitis, is characterized by autoantibodies against NMDA receptor. Patients with anti-NMDAR encephalitis also present with various non-specific symptoms, such as flu-like symptoms, neurological, and psychiatric manifestations. Here, we first reported a rare case of anti-NMDAR encephalitis in a ...

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a recently described and underdiagnosed entity that typically affects young, previously healthy individuals. Patients usually present in phases, which may include refractory seizures, psychosis, unresponsiveness, and autonomic instability. The diagnosis of anti-NMDAR encephalitis is challenging; however, prompt diagnosis and early ...

Hypothermia, defined as a core body temperature of ,35.0°C (,95.0°F), is a life-threatening and emergency situation. Various conditions and diseases can cause hypothermia, including environmental exposure, drug intoxication, CNS diseases, and metabolic abnormalities, such as hypopituitarism, hypoadrenalism, hypothyroidism, and hypoglycemia. Leucine-rich glioma-inactivated 1 (LGI1) antibody– ass...
