As an Internal Medicine Specialist, I work in the Division of Metabolic Diseases of the University Hospital of Padova. Since 2019, I have been the Coordinator of the Rare Metabolic Diseases of Adults Service (Division of Metabolic Diseases-University Hospital of Padova), a multidisciplinary facility dedicated to adult patients with inherited metabolic diseases. I collaborate with Neurologists, Dietologists, Nephrologists, Cardiologists, and many more, who are all experts in the field of rare diseases. I also teach our younger colleagues (both attending Internal Medicine or Endocrinology), trying to improve their knowledge of the adult branch of IMDs, to better understand and diagnose these rare (and often undiscovered) diseases. We have approximately 100 patients referring to our service, most of them affected by carbohydrate (GSD 1a, Congenital Hyperinsulism), lipid (beta oxidation disorders), and protein disorders (organic acidurias and urea cycle disorders) and lysosomal storage diseases (most of them affected by Fabry diseases).
