homovanillic acid/diarrhea

A 23-month-old girl with intractable diarrhea that had persisted for the past 6 months showed typical evidence of water-diarrhea-hypokalemia-achlorhydria (WDHA) syndrome. Serum vasoactive intestinal peptide (VIP)-like immunoactivity was very high, and urine homovanillic acid and noradrenaline were
