Meeting Report: Updates in Diagnosis and Management of Hyperinsulinism and Neonatal Hypoglycemia: Highlights from the Fourth International Hyperinsulinism Symposium.

Hypoglycemia remains a significant cause of morbidity in infants and children. Up to 50% of children with hypoglycemic disorders suffer from neurodevelopmental deficits, as a consequence of delays in the diagnosis and inadequate treatment. Recent advances in the field have resulted in new therapies and improved outcomes. To review these advances and have a dialogue regarding controversies in the field, the Fourth International Hyperinsulinism Symposium, sponsored by the Children's Hospital of Philadelphia was held in Philadelphia, Pennsylvania on September 5-6, 2019. The symposium faculty, leaders in the field of hyperinsulinism and hypoglycemia, presented 25 plenary lectures on all aspects of these disorders. Additionally, a mini-symposium on neonatal hypoglycemia closed out the conference. Objectives of the symposium were to: 1. Describe the clinical manifestations, genetics and natural history of congenital hyperinsulinism 2. Review recent advances in the medical and surgical management of hyperinsulinism 3. Discuss current controversies and management options of neonatal hypoglycemia.
