Both viral and host genetics affect the outcome of herpes simplex virus type 1 (HSV-1) infection in humans and experimental models. Little is known about specific host gene variants and molecular networks that influence herpetic disease progression, severity, and episodic reactivation. To identify such host gene variants we have initiated a forward genetic analysis using the expanded family of ...

Herpes simplex virus-1 has been identified as the trigger factor in certain cases of NMDA-receptor autoimmune encephalitis. We report on a 67-year-old female patient, who was severely affected by post-herpetic NMDA-receptor autoimmune encephalitis. Her symptoms did not improve under methylprednisolone pulse therapy and plasma exchange under acyclovir prophylaxis. She received protein A immunoad...

We report the case of a 64-year old man who presented memory disturbance, low-grade fever, weight loss, and bilateral hand tremors for three months. He was diagnosed with non-herpetic acute limbic encephalitis (NHALE). Follow-up magnetic resonance imaging (MRI) revealed new lesions after symptomatic improvement following steroid pulse therapy. This may indicate that there is a time lag between ...

Background: Herpes simplex encephalitis (HSE) is a fatal infection of the central nervous system. The early diagnosis of HSE is crucial because the early introduction of antiviral therapy can significantly decrease mortality and morbidity associated with this disease. This study was carried out to determine the clinical manifestations, laboratory findings and the outcome of the children admitte...

1. In experimental Type I pneumococcal meningitis of dogs central cord involvement is common after the 2nd day of the disease. 2. These central cord lesions may progress toward extensive suppurative myelitis. 3. Abscesses are infrequent; they arise either as direct perivascular extensions of the meningeal disease or at the site of infected purpuric lesions. 4. In prolonged untreated meningitis ...

An 86-year-old male presented with confusion, fever and tonicclonic seizures. CSF analysis showed lymphocytic pleocytosis and high protein count, leading to initiation of acyclovir. EEG revealed PLEDs in the left hemisphere (figure 1C) and MRI demonstrated left hippocampal and insular hyperintensities (figure 1A, 1B). Herpes simplex virus (HSV) encephalitis was confirmed by PCR. PLEDs represent...

Acanthamoeba is an opportunistic protist pathogen that is ubiquitously distributed in the environment. It is known to produce a sight-threatening, extremely painful keratitis and granulomatous encephalitis [1-4]. Acanthamoeba encephalitis is a fatal brain infection with a case fatality of more than 90%, despite advances in antimicrobial chemotherapy and supportive care. This is partly due to ou...
