Neurovirological research of encephalitides in and around Karachi: the clinical aspects [interim report]

One hundred-and-fourteen cases of encephalitides and encephalopathies were selected from the patients admitted to the Neurology ward Civil Hospital, Karachi [CHK], during the twelve years' period from 1971 to June 1983. There were eleven cases of subacute sclerosing pan encephalities [SSPE] and seven cases of chronic progressive encephalopathies [CPE].

Epidemiology of subacute sclerosing panencephalitis [SSPE] and other encephalitides in Karachi area: a progress note

Relative frequency of neurologic diseases in Karachi, with special reference to inflammatory disorders has been estimated by using the comprehensive data from the Deptt. of Neurology, Dow Medical College, Karachi,The incidence of subacute sclerosing pan-encephalitis has been estimated to be approx. 10 per million. Figures for multiple sclerosis appear comparable to those from India, Turkey and Israel. Rates for active encephalitides and postencephalitic sequelae are unbelievably higher than in the developed countries
