Sir.—The presence of crepitations in the chests of severely dehydrated infants is better known than Drs Farmer and James, who wrote in the June issue of the Journal,1 are aware. DeSanctis and Varga2 wrote, "Auscultatory findings may reveal cardiac arrhythmias that result from alterations in electrolyte concentration as well as from primary cardiac disease and pulmonary rales which may indicate pulmonary edema." However, I must confess that I did not mention the presence of crepitations in dehydrated infants when I wrote on the subject in 1972.3
Dr Farmer did not wish to make a formal reply to this letter.—Ed.
