title: [Abdominal pain syndrome recurring after 40 years: critical revision].
abstract: Recurrent abdominal pain (RAP) syndrome is described by Apley 40 years ago. The definition of condition, still generally accepted, is at least three episodes of abdominal pain over a period of three months, with pain of intensity which affects the behaviour of the child. The prevalence of condition among school children is 10-15%. Apley's classic studies demonstrated organic disease in only 10% of the children. Apley's conclusions have dominated pediatric writing through present era. In recent years, however, a number of reports have appeared in the medical literature that have suggested that careful investigation of children with RAP may reveal previously unsuspected functional or morphologic abnormalities of the gastrointestinal tract. These have included reports of peptic disease and Helicobacter Pylori infection, abnormal antro-duodenal motility, lactase malabsorption, gastro-esophageal reflux. Nevertheless these abnormalities cannot be correlated always with specific complaints. Therefore pathogenetic background is not clarified. Despite greater understanding of these disorders the enigme remains. There is a need for controlled studies in non selected patients.
