Introduction: Neuroglycopaenia is recognised with abnormal neurology and development (Ab Dev) in 26–44% of children with persistent congenital hyperinsulinism (P-CHI). The prevalence of Ab Dev in spontaneously resolving CHI (R-CHI) is not known. We aimed to investigate Ab Dev in R-CHI and P-CHI children in a contemporary cohort.Methods: All children (n=67) were assessed for Ab Dev in the domains of speech, language, motor and vision, and cate...

Introduction: Congenital hyperinsulinism (CHI) causes severe hypoglycaemia, which can be either focal or diffuse in aetiology. Both forms are associated with paternally inherited mutations in ABCC8/KCNJ11. Lymphocytic DNA analysis alone is inadequate to diagnose focal CHI, as pancreatic maternal allelic silencing cannot be tested prior to surgery. Additional 18-fluorodopa PET–CT scanning (PET–CT) is required for definitive diagnosis; in this study, ...
