Subacute sclerosing panencephalitis in Northern Ireland: twenty years' experience.

Subacute sclerosing panencephalitis (SSPE) is a rare degenerative disease of the central nervous system that affects primarily children and adolescents. It is a late manifestation of measles virus infection. In a 20-year period (1965-85) there have been 26 cases of SSPE in Northern Ireland, a frequency of approximately one case per 1.2 million population per year. Males were affected more frequently than females. In other parts of the world the incidence of this disease has been dramatically reduced following effective measles immunisation programmes. The vaccination rate in Northern Ireland probably remains too low to have a similar effect.

Subsets of T lymphocytes in relation to T lymphocyte function in multiple sclerosis.

T lymphocyte control of Epstein-Barr virus (EBV) infection of autologous B lymphocytes was examined in parallel to the enumeration of subpopulations of mononuclear cells in 22 multiple sclerosis (MS) patients and in 22 healthy individuals. All were seropositive for EBV. The incidence of lack of T cell control was significantly higher in patients than in controls, confirming previous published work. In the present study, we have shown in addition a significantly reduced proportion of OKT8+ cells and a significantly increased ratio of OKT4/OKT8 cells in the group of patients with lack of control. The findings point to abnormal immunoregulation in MS.

Carotid artery thrombosis, encephalitis, myelitis and optic neuritis associated with rubella virus infections.

The clinical, virological and pathological findings in 5 patients with neurological complications associated with rubella virus infection are described. The neurological illnesses began four to ten days after the rubella illnesses. The patients were all males aged between 6 and 17 years and were diagnosed during one non-epidemic year in a population of 1-5 million people. All the patients had rubella specific IgM in their sera. Two patients had no rash. In one of the patients who died, left internal carotid artery thrombosis and cerebral infarction were found at post-mortem. Rubella virus antigen and particles resembling rubella virus were found in the brain together with IgG and IgM in the same areas. This patient also had extensive liver necrosis. The other patient had a severe meningomyelitis and radiculitis and he recovered completely after two years. His serum rubella antibody rose significantly and was shown to leak into CSF during the acute stage of his illness. Three patients had a rash. Two of these patients had encephalitis: one recovered completely and the other had residual disability. The third patient had bilateral optic neuritis from which he recovered completely. Rubella specific IgM was, however, present in his serum for the abnormally long time of twenty-eight weeks indicating possible persistence of rubella virus.
