Chapter 51: Endocrine Disorders in Pediatric Patients

Endocrine Disorders in Pediatric Patients overview explores the multifaceted world of pediatric endocrinology, focusing on the hormonal regulation of growth, metabolism, fluid balance, and sexual development in children. The text begins with pituitary dysfunction, contrasting growth hormone deficiency and its resulting short stature with hyperpituitary conditions like gigantism and acromegaly. It examines the complexities of precocious puberty, distinguishing between central and peripheral origins, while also addressing posterior pituitary disorders such as diabetes insipidus, characterized by uncontrolled diuresis, and the syndrome of inappropriate antidiuretic hormone (SIADH), which leads to fluid retention and hyponatremia. Significant attention is given to thyroid health, detailing the management of juvenile hypothyroidism, Hashimoto’s thyroiditis, and the autoimmune-driven Graves' disease, alongside parathyroid imbalances that disrupt calcium and phosphorus homeostasis. Adrenal conditions are meticulously reviewed, including the life-threatening nature of acute adrenal insufficiency, the chronic management of Addison disease, the distinct physical hallmarks of Cushing syndrome, and the genetic complexities of congenital adrenal hyperplasia, which may present as ambiguous genitalia or salt-wasting crises. A major portion of the material is dedicated to the metabolic challenges of diabetes mellitus, contrasting the autoimmune-mediated absolute insulin deficiency in type 1 diabetes with the lifestyle-influenced insulin resistance characteristic of type 2 diabetes. The discussion emphasizes critical nursing interventions, ranging from the recognition of diabetic ketoacidosis and the nuances of insulin pump therapy to the psychological support required for families navigating chronic endocrine management. By integrating concepts of physiological feedback loops with patient-centered education and lifestyle modification, the summary provides a vital framework for nursing students and educators to understand how hormonal imbalances impact pediatric growth and long-term health outcomes.
