Problems in the Diagnosis of Cyclic Vomiting Syndrome in Children.

The cyclic vomiting syndrome (CVS) is an infrequent condition in pediatric practice, in which recurrent vomiting episodes are followed by asymptomatic periods. The authors report the case of an 8-year and 2-month old child who had been hospitalized on several occasions for persistent vomiting accompanied by nausea, and periumbilical and epigastric abdominal pain. The child's anamnesis and clinical examination determined the doctors to suspect aCVS, which was later confirmed due toruling out all of the differential diagnoses: infectious, drug-related or surgical causes. CVS is a severe condition, which causes nutrition disorders, social integration problems, school absenteeism and lower life quality on the whole. This condition requires early detection in order to initiate adequate supportive therapy, to identify the triggering causes and to prevent them.
