Convulsions are a common symptom in pediatrics. In spring and summer, febrile convulsions often occur because of the high number of febrile children. When autumn and winter arrive, children often have diarrhea, and some of them may have convulsions because of diarrhea or vomiting. Most children are clinically referred to as pediatric convulsions with gastrointestinal symptoms. Clinical manifestations and diagnostic criteria: (1) 6 months to 24 months old children with febrile convulsions with gastrointestinal symptoms; (2) short duration of each convulsion, which may occur in clusters (multiple convulsions within 24 hours); (3) normal CT or MRI, normal cerebrospinal fluid, normal or abnormal EEG boundaries (abnormal waves from central and parietal areas); (4) normal motor intelligence. It is necessary to exclude: (1) first seizure of epilepsy; (2) intracranial infection. Treatment: symptomatic. Pay attention to cod liver oil supplementation, and you can take appropriate B vitamins. Prognosis and prevention: Good prognosis. Few can have a second seizure. Re-seizure children, if EEG is not good, should be treated for a long time. No vaccination for six months.
