An unfortunate error appeared in the Seminar article in the September, 1960, American Journal of Diseases of Children which was entitled "Congenital Virilizing Adrenal Hyperplasia," page 422 of this volume. Under a discussion of therapy, the author states that "... desoxycorticosterone acetate (Percorten) 25 mg/cc. may be employed intramuscularly every 25 to 30 days. The dose is 1 cc. every 25 to 30 days...." The statement should read "Desoxycorticosterone trimethylacetate (Percorten trimethylacetate) 25 mg/cc. may be employed intramuscularly every 25 to 30 days." DCA trimethylacetate is the long-acting derivative which may be given every 25 to 30 days. Desoxycorticosterone acetate is the "short-acting" form which is given daily in doses of 1 to 2 mg. We suggest you clip this item and insert it at page 422.
