Hamsters are very susceptible to infections with herpes simplex virus. Inoculation of the skin of the lower back region leads to an ascending involvement of the central nervous system with fatal outcome. This model was used for testing the activity of antiviral substances in herpes infections of the nervous system. Acyclovir given in optimal dosages prevented infection of the central nervous system completely even when therapy was started 48 hours after inoculation. Therapy with acyclovir proved to be successful in animals showing paresis after infection even when the drug was given in lower than optimal dosages.

A 22 weeks pregnant women was affected by a life-threatening pneumonia and a paresis of the proximal muscles with cerebrospinal fluid pleocytosis. Her past medical history had been unremarkable except for recurrent episodes of paraumbilical herpes zoster. The clinical findings suggested a dissemination of varicella-zoster virus without skin lesions. Acyclovir was added to the therapy, and the clinical picture began to improve. Varicella-zoster virus DNA was detected in placental tissue by DNA-hybridisation analysis.

Bell's palsy or idiopathic palsy is the most common disorder affecting the facial nerve. Diagnosis is primarily one of exclusion. There is typically an acute unilateral facial paresis that evolves in 24 to 48 hours. Etiology and pathophysiology are heavily disputed, and as of yet unknown. The natural history of Bell's palsy is favorable. Eight-four percent show satisfactory recovery without any treatment, however 16% suffer moderate to severe sequelae. Prognosis is influenced by degree of paresis, age of patient, and time until first signs of recovery. Prognostic testing currently involves various electrophysiological tests. More than 90% degeneration of the facial nerve carries a poor prognosis for recovery; these are the patients who may benefit from facial nerve decompression surgery. If surgery is performed it should be done early (< 21 days from onset of palsy) and should include a middle cranial fossa decompression. Steroids are generally agreed to be beneficial. Acyclovir would seem to be a promising drug; however studies have not adequately assessed its use.

Identical twin brothers developed mild encephalopathy at the age of 7.0 and 9.7 years (Patient 1) and 10.7 years (Patient 2). Patient 1 had influenza A at the time of his second episode, but triggering agents were not evident at the first episode. The triggering agents in Patient 2 were unclear. The neurological features of both patients included transient facial numbness, left arm paresis, dysarthria, and gait disturbance. Diffusion-weighted images from magnetic resonance imaging showed high signal levels at the splenium of corpus callosum and in the bilateral cerebral deep white matter. These results are characteristic of mild encephalitis/encephalopathy with a reversible isolated splenium of corpus callosum lesion. All three episodes were treated with a methylprednisolone pulse. Acyclovir was also administered to Patient 2 and to Patient 1 during his first episode. Patient 1 received an anti-influenza agent and intravenous immunoglobulin during his second episode. Both patients recovered completely without sequelae. Genetic factors, which may predispose identical twins to develop encephalopathy, are discussed.
