Benign infantile seizures associated with gastroenteritis and benign infantile seizures alone in the same patients: Related syndromes or coincidental entities?

We report two patients, the first one had benign infantile seizures (BIS) associated with gastroenteritis (BISG), followed by BIS without gastroenteritis, in the second patient BIS was followed by BISG related to anti-rotavirus vaccine. After 12 and 6 months of follow-up, both patients had normal psychomotor development. BISG may be a situation-related seizure, a coincidental entity associated with BIS. However the case evolutions suggested that both BIS and BISG are related syndromes.
