Childhood Diseases & Disorders, ACR-VEN

Although the diseases of childhood are largely similar to those of the adult, there are several important differences. Certain specific disorders are unique to children; others, such as acute nephritis—inflammation of the kidney—are common in children and infrequent in adults. Additionally, a major segment of pediatric care concerns the treatment and prevention of congenital anomalies, both functional and structural.
