Background: Insulin dose requirements are higher during puberty and in overweight/obese individuals with type 1 diabetes mellitus (T1DM) due to insulin resistance. Through meta-analysis metformin has been shown to be beneficial as adjunctive therapy in T1DM adults independent of BMI. The large volumes of insulin required to administer higher insulin doses in insulin-resistant individuals have adverse effects on insulin absorption. Insulin degludec (Tresiba) U200 preparation al...

Introduction: Congenital hypothyroidism (CH) occurs 1 in 3,000-4,000 live-births. The causes of CH can be divided into two groups: thyroid developmental defects (thyroid dysgenesis) and inborn errors of thyroid hormone biosynthesis (dyshormonogenesis). Although mutations in paired box gene 8 (PAX8) usually cause thyroid dysgenesis, they have been reported in association with eutopic thyroid gland without function. PAX8 has been described to have a role in regulating the expres...

Background and ObjectiveData on the epidemiology, effects of dopamine agonists and long term outcome of prolactinoma in children and adolescents have been gradually accumulating but are still scarce. We conducted a systematic review and meta-analysis of published literature (1994 – 2019) to study the epidemiology of prolactinoma in patients < 20 years old, and determine the management strategies adopted.Methods: Relevant ...

Introduction: Paired box gene 8 (PAX8) is a key transcription factor required both for normal fetal thyroid development and maintenance of the differentiated thyroid phenotype, mediating transcriptional activation of SLC5A5, TG, and TPO, and synergizing with NKX2-1 at the TG promoter. Heterozygous PAX8 mutations are a rare but well-recognized cause of congenital hypothyroidism (CH) due to thyroid dysgenesis (TD), and are classically associated with thyroid hypoplasia. However,...

Introduction: Pituitary inflammation (Hypophysitis) is rare in paediatric population and usually results in pituitary enlargement and hypopituitarism. Hypophysitis can be either primary (most commonly lymphocytic, granulomatous or xanthomatous disease) or secondary (consequent to systemic diseases, immunotherapy or alternative sella-based pathologies). We describe the clinical presentation and management of apparent primary lymphocytic hypophysitis in an adolescent girl. Case ...
