[Benign afebrile seizures in rotavirus gastroenteritis].
Benign afebrile seizures associated with mild gastroenteritis and normal serum electrolytes are often described in Asian infants under the name of convulsions with mild gastroenteritis (CwG). Herein, we report 3 cases of CwG that occurred in Caucasian children. Clinical features and outcomes are described and the cases reported in the literature are reviewed. The CwG syndrome is now recognized as a distinct entity characterized by the following criteria: (1) it occurs in previously healthy 6-month to 3-year-old children who present with afebrile convulsions, (2) it is associated with mild gastroenteritis, (3) seizures tend to occur in a clustered manner, (4) interictal EEG shows no paroxysmal discharge, and (5) laboratory examinations are normal, including normal cerebrospinal fluid, serum electrolytes and glycemia. The CwG syndrome is a self-limited disease with a short course and a good prognosis. Investigations must be targeted and anticonvulsivant therapy is not required. As rotavirus is the most common agent among the diarrheal viruses detected to be the cause of CwG, one could hypothesize that this virus may play a role in the CwG pathogenesis.
