Neurological complications in hospitalized patients with pertussis: a 15-year Sicilian experience.

Three hundred forty patients were diagnosed with pertussis infection at the Pediatric Clinic of the University of Catania, Sicily during the period 1979-1994. None of these patients had been previously vaccinated. Fourteen developed neurological complications at some point in their course, which took the form of seizures (both febrile and afebrile) and, in some cases, encephalopathy. Serious permanent neurological sequelae were not observed in this series of patients though they had pertussis severe enough to require hospitalization.
