The Editorial Board is pleased to respond to Dr. Kaplan’s letter of March 27, 2002.  His article in The Endocrinologist has been updated and is published in response to his letter to the Editorial Board.  We believe Dr. Kaplan has succinctly summarized the current knowledge in respect to the inter-relationships between IGF-I, hGH, and growth.  Thank you, Dr. Kaplan.
