Childhood rubella encephalitis: diagnosis, management, and outcome.

We to report clinical biological and radiologic features of rubella encephalitis in childhood and assess its prognostic impact. Our retrospective study was conducted in an intensive care unit of a university hospital in Sfax, Tunisia. Twenty-one children (age range, 1-15 years) were included. Median age was 9 years (lower and upper quartiles, 7-11 years). On admission, generalized maculopapular eruption was found in 17 cases (81%). Median Glasgow Coma Scale score was 7 (lower and upper quartiles, 7-8). Twenty patients (95.2%) experienced at least 1 episode of seizures. Sixteen patients (76.2%) developed a status epilepticus. The result for enzyme-linked immunosorbent assay detecting anti-rubella immunoglobulin (M) was positive in the serum and in the cerebrospinal fluid samples for all our patients. Magnetic resonance imaging (MRI) of the brain was performed on admission for 3 patients (14.3%) and within a median of 4 days (lower and upper quartiles, 2-6 days) for 8 patients. The test was normal in 6 cases. Two deaths were recorded (9.5%). Survivors had no neurological sequelae 6 months after intensive care unit discharge.
