The technic of the practice of medicine represents a field which is constantly increasing in scope. This book details the diagnostic, therapeutic and dietetic methods employed in the Hospital for Sick Children in Toronto. Discussion of the procedures employed is not included. Rather, the text presents in a brief form the procedures found to be useful in common conditions in hospital practice. The chapters on history taking in infants and children, feeding the infant and child, and therapeutic and diagnostic procedures are especially valuable because of their simplicity, brevity and practical application. The chapter on difficulties in diagnosis deals with many not uncommon disorders, obtained from a review of hospital records, which offered a problem in etiology. In the present edition new sections have been added on feeding, behavior problems, intelligence tests, eczema and related subjects. The book should be of value to interns and general practitioners for practical reference.
