Herpes simplex infection of the CNS may occur as part of a generalized infection with visceral involvement or with the CNS alone involved. Aseptic meningitis due to herpes simplex is rare, but necrotizing encephalitis is being recognized with increasing frequency. The distribution of lesions within the CNS and the mode of spread to and within the CNS are discussed. Serological tests indicate th...

acyclovir (9-[2-hydroxyethoxymethyl] guanine) is an acyclic nucleoside analogue of guanosine which is a potent and selective antiviral agent. acycloviris converted to the monophosphate by thymidine kinase the virus-specific form of this enzyme and is subsequently converted to the triphosphate by the host cell kinase. acyclovir triphosphate inhibits viral dna-polymerase terminating the chain and...

Acute confusion and memory loss associated with asymmetrical mesiotemporal hyperintensity on T2-weighted MRI are characteristic of herpes encephalitis. The authors report the case of a patient with these symptoms and MRI presentation who had neurosyphilis. Recently clinical and imaging patterns usually associated with herpes simplex encephalitis have been seen in patients with neurosyphilis. Be...

Equine herpesvirus 1 replicated in the brains of 2-week-old mice but did not produce fatal encephalitis; it thus simulated the majority of cases of herpes simplex encephalitis in man. This replication was not inhibited by iododeoxyuridine, although in tissue cultures the equine and human viruses were equally susceptible. The continued use of iododeoxyuridine for human encephalitis should be ser...

Encephalitis is a disease characterised by inflammation of the encephalon. An important element to take into account in this pathology that it has several causes, among which viral and metabolic are most important. This clinical picture generally manifests itself with headache, altered mental state, seizures, focal signs, movement disorders, some cases also manifested meningeal or cortical depe...

Herpes simplex encephalitis is a potentially fatal infection of central nervous system that typically involves frontal and temporal lobes. Occasionally, it presents an extratemporal involvement and in rarer cases, it is limited to the brainstem. We describe a case of an adolescent who presented with fever, sore throat, and vertigo. Clinical picture evolved to lethargy, tetraparesis, consciousne...
