Chapter 25: Children: Infancy through Adolescence

Children: Infancy through Adolescence focuses on the clinical assessment of children from birth through late adolescence, providing a detailed framework for pediatric history taking and physical examination. It establishes core principles of development, highlighting that growth follows a predictable trajectory while maintaining a wide range of typical variance influenced by genetic and environmental factors. The text outlines the critical domains of developmental surveillance—physical motor skills, cognitive problem-solving, language articulation, and social-emotional relationship building—while advocating for the use of standardized screening tools and the calculation of a developmental quotient, where a result (greater than) 85 is typically considered normal. For neonates and infants, the guide details essential birth assessments such as the Apgar score and Ballard Scoring System for gestational age, alongside meticulous tracking of somatic growth using World Health Organization and CDC charts to identify variations (lesser than) the 5th percentile. It covers specialized examination techniques for the pediatric population, including the evaluation of fontanelles, red retinal reflexes, and primitive automatisms like the Moro and palmar grasp reflexes. As patients progress into middle childhood and adolescence, the clinical approach shifts toward fostering rapport, ensuring patient modesty, and utilizing the HEEADSSS psychosocial framework to identify health risks. Detailed attention is given to the Tanner sexual maturity ratings, scoliosis screening, and the specific requirements for sports preparticipation evaluations. Throughout the age spectrum, the chapter emphasizes health promotion through routine immunizations, metabolic screenings, and anticipatory guidance to support families in navigating nutritional, safety, and behavioral challenges.
