[Evaluation of diagnostic and therapeutic methods in hyperinsulinism in newborn infants and infants. Apropos of a retrospective study of 26 cases].

This report concerns 26 cases of hyperinsulinism in neonates and infants. Clinically, the syndrome beginning in the neonatal period seems to differ by several aspects from the disease with a later onset: diagnostic difficulties, treatment modalities and long term prognosis. Insulinemia determined when the patient presents with hypoglycemia is often (75 to 80% of cases) normal.
