An 18-year-old female had common cold and insomnia in early March 1987. Later, abnormal speech and behavior, emotional incontinence, anorexia and consciousness disturbance appeared. On March 19, she was admitted to our hospital in semi-comatose state. Myoclonus-like movement on hands was observed, and epileptic attacks with tonic and clonic convulsions occasionally occurred. There were no neurological findings that suspected cerebral focal lesions. The respiration was assisted through tracheal intubation. Laboratory examinations showed inflammatory reactions (CRP+2, WBC 10,600) and transient high levels serum CK (6,215 IU). As she had bradycardia (30-40/min) with complete AV block on ECG, the pacemaker was implanted. The complication of myocarditis was suspected. EEG showed bilateral slow waves (3-6Hz), dominantly in frontal areas. Brain CT and CSF examinations were normal. After the combined administration of ara-A, dexamethasone and anti-convulsant, the consciousness level was recovered within a month. The serum antibody against coxsackie virus B4 alone was significantly increased. We concluded that coxsackie virus B4 caused acute encephalitis with mental symptoms and myocarditis with AV block. Recently, cytomegalovirus was reported to be the causative virus in a young female with non-HSV encephalitis who showed mental symptoms with good prognosis, but coxsackie virus B4 should also be considered as one of the causative viruses.

Five patients with spontaneously recovering Dancing Eye Syndrome/Opsoclonus Myoclonus Syndrome are described. Age at presentation ranged from 4 to 19 months. Four had symptoms of fever and a coryzal illness within days to a few weeks prior to the onset. One of the 4 also had varicella zoster 4 weeks before presentation. All had opsoclonus, myoclonus/ataxia and irritability. Associated infective agents identified were Coxsackie virus and rotavirus. Spontaneous improvement of symptoms started within 9 days of presentation and total duration of illness ranged from 10 to 24 days. Developmental progress at follow-up was normal in all cases. A range of immunomodulatory therapies have been advocated for the treatment of Dancing Eye Syndrome/Opsoclonus Myoclonus Syndrome. However, in some children, early spontaneous recovery may occur, an observation which should be borne in mind when designing therapeutic trials in this condition.

Opsoclonus-myoclonus-ataxia (OMA) syndrome is a rare neurological disorder, characterized by a rapid onset of generalized myoclonus in association with chaotic multi-directional eye movements and, less frequently, cerebellar ataxia. OMA is commonly related to a paraneoplastic process, specifically neuroblastoma in children and lung or breast cancer in adults. Nevertheless, OMA may occur in association with various infectious agents, such as Coxsackie virus B3, Epstein-Barr virus, mumps, enterovirus, and streptococcus. We recently encountered two cases of HIV-related OMA syndrome. The first patient developed a sudden onset of OMA at the time of HIV seroconversion. The second patient experienced severe ataxia with a mild degree of myoclonus and opsoclonus, associated with an elevated CD4 count following the initiation of highly active antiretroviral therapy (HAART). We suggest that OMA syndrome may be another rare manifestation of HIV infection at the time of seroconversion or during an immune restoration period.
