Reiter's syndrome in an adolescent girl.

This report describes a 14-year-old girl who presented with an Escherichia coli urinary tract infection followed by diarrhoea, arthritis and iritis. She had continuing symptoms intermittently for six months, but was HLA-B27 antigen negative. The occurrence of Reiter's syndrome is unusual in young females and we are not aware of any reports of reactive arthritis following E. coli urinary tract infection in children.
