Readers of this book can update their knowledge in the fast-moving field of endocrinology and neurobiology. Topics concerning growth and development are extensively reviewed from both basic science and clinical viewpoints. Aspects related to growth development and to the control of cellular differentiation and multiplication are discussed. Further new information is provided on: synthetic recombinant human growth hormone (rHGH); potential diagnostic and therapeutic applications of the neuropeptide, growth hormone releasing hormone (GHRH); the physiology and physiopathology of the neural control of growth hormone secretion; the diagnosis and therapy of growth hormone deficiency or excess states; and the biology, function and possible utilization of growth factors. These important new findings are relevant to progress in pediatrics, pediatric and clinical endocrinology, neuroendocrinology and physiology.
