In the 1950's a few creative physicians working in Africa and other parts of the tropical world, developed appropriate ambulatory clinical services for children. They reorganized patient flow in clinics and they faced the issue of overwhelming patient numbers by development of protocols for the management of common problems by health auxilliaries. Today their changes and ideas are taken for granted and made part of the status quo throughout the world. These concepts, interestingly enough, are beginning to permeate the ranks of primary care providers in countries such as the United States; in this instance, we are learning from the third world. This book embodies the full flowering of these ideas and provides a first class manual for all levels of those who provide primary health and medical care. It is a complete text written in simple terms. For the upper level professional it can be digested quickly and serves as an orientation manual to the pediatrics and child health of the impoverished tropics.
