Written specifically for the primary care physician, this practical management guide focuses on the biological and behavioral problems most frequently encountered in primary care. The discussions are formatted to approximate the procedure physicians typically follow when presented with a child patient and cover problems in order of prevalence, uniquely suiting this work as a diagnostic and management guide. Each section describes the problem and its frequency as well as the strategies used to arrive at a diagnosis, and then scientifically evaluates the evidence supporting suggested management strategies. Common behavior disorders, for which primary care physicians often receive little training, are treated extensively, as are controversies in nutrition and preventive health care.
