Late-onset chronic progressive panencephalitis developed in a 12-year-old boy with congenital rubella syndrome from whose brain rubella virus was isolated. Progressive dementia began at eight, and ataxia, choreiform movements, myoclonic seizures, and fine perimacular pigmentation appeared at 11 years of age. The cerebrospinal fluid was minimally pleocytotic and had a total protein of 156 mg per deciliter, of which 52 per cent was gamma globulin. Electroencephalography demonstrated generalized medium and occasional high-voltage slowing without burst suppression. The antibody titer to rubella virus (hemagglutination inhibition) was 1:8192 in serum and 1:256 in cerebrospinal fluid. Antibody titer to measles virus (complement fixation) was less than 1:8 in serum. Microscopical study of biopsied brain tissue at the age of 11 disclosed panencephalitis similar to subacute sclerosing panencephalitis, but with perivascular deposits and without inclusion bodies. Rubella virus was isolated from the brain by cocultivation with CV-1 cells.

Diseases of the central nervous system (CNS) occurring during treatment of acute lymphoblastic leukemia (ALL) may be of leukemic or nonleukemic origin. Well known examples for CNS disease of nonleukemic origin are somnolence following prophylactic CNS irradiation, methotrexate-induced encephalopathy and acute infections caused by bacteria, viruses and toxoplasma gondii. Less known is the fact that also subacute CNS infections may occur in patients undergoing cytostatic therapy. Progressive multifocal leukoencephalopathy and subacute sclerosing panencephalitis (SSPE) are examples of this category of disease. Up to now 11 well documented cases of SSPE were reported occurring during treatment of ALL. Main clinical features were disorders of behaviour, consciousness and speach, seizures, paresis and inappropriate secretion of ADH. Several authors were able to demonstrate a deficiency of cellular immunity in patients with SSPE. In some cases this deficiency was consistent with reduced reactivity of T-lymphocytes against measles antigen only. The presence of inhibiting factors may be responsible for this phenomenon. Other authors found a normal or increased function of cellular immunity in SSPE; In hamsters occurrence of SSPE is induced by the simultaneous injection of hamster-adapted SSPE virus and antihamster lymphocyte serum. We, therefore, conclude that also in humans SSPE appearing during treatment of ALL is due to immunosuppression.

We report a seven-year follow-up of identical twins, in one of whom subacute sclerosing panencephalitis (SSPE) developed. Primary measles infection occurred simultaneous in both twins at age 4. The affected twin sustained a grade 1 closed head injury within six months of her primary measles infection. At age 13, SSPE was diagnosed following the onset of personality change and myoclonic seizures. Measles antibody level was elevated in the serum and CSF. After remaining in stage 2 for five years, rapid mental and neurological deterioration occurred. Measles antibody level remained elevated, and oligoclonal IgG was present in both serum and CSF. Results of neurological examination as well as virological and immunological tests were normal in the unaffected twin. Besides the occurrence of head injury, factors known to be associated with SSPE were not obviously different in the twins. We have been unable to determine a difference that would easily explain the occurrence of SSPE in only one of two identical twins.

Subacute progressive panencephalitis is usually a progressive and fatal disease, being uncommon temporary or definitive remissions. A three years old boy, previously vaccinated against measles, developed trembling, progressive and severe mental deterioration, partial seizures and myoclonic jerks. The electroencephalogram showed periodic high amplitude waves concomitantly with myoclonic jerks and the cerebrospinal fluid revealed an increase of the gammaglobulin fraction (16,8), benjoin coloidal reaction shifted to the left and the antimeasles antibody titres were positive (complement fixation text 1:16; neutralization test 1:32). In spite of that, two months after the beginning of the illness the patient showed mental and motor improvement and similar modifications of the electroencephalographic aspects and now, eleven months later, is well, remaining only a slight motor and mental deficiency.

EEGs of 18 cases of measles (uncomplicated, with seizures, with encephalitides) were obtained through an underground cable connection between the Infections Diseases Department and the EEG unit. The varions EEG features of the disease have been studied during the evolution of the illness. An occasional EEG does not offer specific information on either the severity or the evolution of the disease. Marked EEG abnormalities appeared in the encephalitic group. The Authors emphasize the importance of serial prolonged EEG follow-up of measles in order to define precisely the stage and the evolution of the disease.

Five patients with an unusual encephalopathy, possible secondary to measles virus infection, are described. Features common to these patients are: an existing chronic disease, neurologic deterioration 2 1/2 to 6 months after a measles infection, and death several weeks later. These events occurred when the chronic disease (e.g. leukemia or neuroblastoma) was in remission. That the measles virus was the causative agent is suggested only by finding in brain and extracranial tissues intracytoplasmic and intranuclear inclusions which contained measleslike particles. Additional clinical features seen in each of the five patients were: seizures, hypertension, and the inappropriate secretion of antidiuretic hormone.

Subacute sclerosing panencephalitis (SSPE) has become rare since the widespread use of the measles vaccine. In this patient with a 5 month history of seizures and progressive dementia due to SSPE, the atypical electroencephalographic pattern was characterized by generalized spike-and-wave discharges, maximal on the right, associated with clinical seizures. After diazepam (intravenously), more typical periodic complexes appeared.

A retrospective study of 36 confirmed cases of subacute sclerosing panencephalitis (SSPE) was carried out to detect any variation in the clinical and EEG patterns previously described. There were 31 males and 5 females, aged 4 to 24 years. Onset of SSPE at or after 15 years of age was observed in 22.2% of cases. Rapid progression of the disease was observed in 52%. The first symptom was myoclonus in 61.6%, mental regression in 22.2% and generalised seizures in 11.1% of cases. Low positive measles antibody titres in the CSF were found in 36.1% of cases. EEG analysis revealed slow background in 69.2% and periodic complexes in 94.4% of cases. Atypical periodic complexes, focal abnormalities and paroxysms of bisynchronus sharp activity were also observed.

To evaluate the risks of seizures and other neurologic events following measles-mumps-rubella (MMR) or measles-rubella (MR) immunization, a retrospective cohort study was conducted among 18,364 Tennessee children enrolled in Medicaid who received MMR or MR immunizations in their first 3 years of life. One hundred children had seizures at some time between immunization and 36 months; there were no encephalopathies during this period. Four children had febrile seizures in the 7 through 14 days following MMR or MR immunization compared with 72 in the interval 30 or more days following MMR or MR immunization yielding a relative risk (95% confidence interval) of 2.1 (0.7 to 6.4). Although not statistically significant, this increase in febrile seizures in the 7- through 14-day interval following MMR immunization is coincident with the occurrence of fever following MMR immunization and is consistent with reports of other investigators.

Multiple sclerosis lesions may occur predominantly in the hemispheric white matter and cause various psychiatric disorders such as remitting-relapsing endoform or exogenous psychosis, organic personality alterations and dementia. Nineteen patients suffering from this encephalitic form of multiple sclerosis as diagnosed by characteristic CSF immunoglobulin findings are analysed according to established psychopathological criteria. All cases began with psychiatric symptoms and neurological signs were either absent or overlooked. Several patients developed typical encephalomyelitic symptoms in successive relapses, but other remained with psychiatric disorders over many years. Only four patients had retrobulbar neuritis, but seven suffered from epileptic seizures. The humoral immune response was characterized by a strong dominance of IgG and a local synthesis of polyspecific antibodies against measles, rubella and varicella/zoster virus. The mononuclear CSF pleocytosis was comparatively marked with cell counts up to 180/microliter.
