  RESULTS
  This article discusses the pathophysiological mechanisms, clinical presentation and treatment of the various forms of diabetes that affect the pediatric age group, such as type 1 diabetes mellitus , type 2 diabetes mellitus, maturity-onset diabetes of youth, neonatal diabetes, mitochondrial diabetes, diabetes of generalized lipodystrophy, diabetes secondary to other pancreatic diseases, diabetes secondary to other endocrine diseases, diabetes associated with infections and cytotoxic drugs and diabetes related to certain genetic syndromes.
