Increasing trend of type 1 diabetes incidence in the pediatric population of the Calabria region in 2019-2021.

Background: Although type 1 diabetes (T1D) represents one of the most common chronic diseases in pediatric age, few studies on the epidemiology of T1D exist globally and the exact prevalence and incidence rates of the disease are unknown. In many countries, including Italy, national registries are missing.

Methods: This study aims to assess T1D incidence in the pediatric population of the Calabria region (southern Italy) in the period 2019-2021.

Uniparental disomy and pretreatment IGF-1 may predict elevated IGF-1 levels in Prader-Willi patients on GH treatment.

Pediatric patients with Prader-Willi syndrome (PWS) can be treated with recombinant human GH (rhGH). These patients are highly sensitive to rhGH and the standard doses suggested by the international guidelines often result in IGF-1 above the normal range. We aimed to evaluate 1 the proper rhGH dose to optimize auxological outcomes and to avoid potential overtreatment, and 2 which patients are more sensitive to rhGH.

Erythrocyte Galactose-1-phosphate measurement by GC-MS in the monitoring of classical galactosemia.

Background: Classical galactosemia is a rare but very severe disease characterized by a deficiency of the galactose-1-phosphate uridyltransferase enzyme. The confirmed galactosemic patients are treated with a galactose-restricted diet. Nevertheless, metabolites such as galactose-1-phosphate can accumulate in red blood cells of treated patients and its measurement is a standard practice for their monitoring.
