exanthema subitum/seizures

A 15-month-old girl developed frequent seizures at the eruptive stage of exanthema subitum. The eruption persisted for 2 weeks. Serum immunoglobulin G antibody to human herpes virus type 6 (HHV-6) increased markedly. Interleukin-6 was elevated whereas HHV-6 deoxyribonucleic acid was not detected in

We report here three infants with frequent convulsions in the post-eruptive stage of exanthem subitum (ES) due to human herpesvirus 6 (HHV-6) infection. Postictal electroencephalogram (EEG) showed in all the patients abnormal epileptic discharges, which disappeared in the following by three to

We examined long-term neurological outcome of 12 patients, whose first febrile seizures had occurred during exanthema subitum (ES) and who had been treated with continuous daily administration of anticonvulsant drugs. Six of 12 children had a family history of febrile or afebrile convulsions and in

Enterovirus focal encephalitis is a rare clinical entity that is characterized by focal neurological signs including seizure, hemiparesis, hemichorea, and headache, which are mainly followed by rapid spontaneous improvement. We herein describe the case of a 9-month-old boy who developed Coxsackie

The DNA detection of human herpes virus (HHV) 6, 7 was performed in the patients who visited to the Nakano children's hospital because of their initial febrile seizures (FS). Those patients included 35 boys and 21 girls under 3 years of age (mean: 1 year 4 months). DNAs of HHV 6, 7 in the

Human herpesvirus 6 (HHV-6) is a ubiquitous virus that causes the childhood febrile illness exanthem subitum. Primary infection usually occurs in the first few years of life and the virus is considered to be one of the most common causes of acute febrile illness in childhood. HHV-6 can infect the

In general, epileptic seizures become more serious following infections. However, transient and permanent improvement of epileptic seizures has been observed following acute viral infections, without a recent change in anti-epileptic therapy. Questionnaires were sent to 73 institutions, throughout

Two infants developed unilateral hippocampal swelling on magnetic resonance imaging after prolonged seizures of temporal origin. Subsequent images suggested hippocampal sclerosis. The first child had febrile status epilepticus with exanthem subitum and developed refractory complex partial seizures.

OBJECTIVE Febrile convulsion is a common disorder in children. Viral infections such as human herpes virus 6 (HHV-6) which results in roseola infantum may contribute to developing seizure. The objective of this study was to determine the prevalence of HHV-6 by detecting DNA in cerebrospinal fluid
