title: Cystic fibrosis presenting with recurrent vomiting and metabolic alkalosis.
abstract: Between January 1980 and December 1987, ten Saudi Arabian children at Saudi Arabian Oil Co. (Saudi Aramco) health care facilities in the Eastern Province of Saudi Arabia had cystic fibrosis (CF). The incidence of CF in Saudi Arab children less than or equal to 14 years was 1 in 4243. Five of the ten children had hypoelectrolytaemia and metabolic alkalosis on initial presentation. Two of the five had recurrent vomiting, hypoelectrolytaemia and metabolic alkalosis alone and initially no chest symptoms. Early exclusion of CF should be part of the workup in any child, especially in an infant with hypoelectrolytaemia and metabolic alkalosis.
