Pediatric Nephrology Discussion 1: Edema
	In pediatrics, edema is an uncommon physical finding. A thoughtful history and examination may allow the practitioner to identify the etiology of the edema state. Edema may be brought about through a variety of mechanisms. An understanding of the pathophysiology of edema may allow the practitioner to identify the disease state in the patient and to formulate an initial plan of management. Allergic, cardiac, cirrhotic, nephrotic, and nephritic edema states are discussed below. Expanded discussions of nephrotic and nephritic edema may be found, with links to recent articles reviewing the other types of edema.
