Standard method for developing stroke registers in low-income and middle-income countries: experiences from a feasibility study of a stepwise approach to stroke surveillance (STEPS Stroke).

Background: Stroke is a leading global cause of death, with an estimated 5.8 million fatal events in 2005, two-thirds of which happened in low-income and middle-income countries. In these regions, epidemiological methods to establish hospital-based stroke registers for clinical audit or studies to estimate incidence are scarce.

High incidence of subacute sclerosing panencephalitis in south India.

During 1983-7 a clinical diagnosis of subacute sclerosing panencephalitis (SSPE) was confirmed by the detection of measles virus haemagglutination inhibiting antibody in the cerebrospinal fluid (CSF) in 81 subjects resident in Tamilnadu. The antibody titre (reciprocol of the end-point dilution) in the CSF ranged from 2 to 32 and in the sera from 8 to 2048. The CSF:serum ratios of titres were 1:4-1:64 in 80 cases and 1:128 in one case.
