Brief summary: In 2021 and 2022, two important publications on pediatric thyroid carcinomas revealed a distinct molecular landscape compared to adult thyroid carcinomas (1,2). Pediatric differentiated thyroid carcinoma was mainly caused by fusion oncogenes, especially in children younger than 10 years (93%), compared to children aged 10–15 years (28%) and 15–20 years old patients (14%). In contrast, PTC due to BRAF mutations showed increasing frequency with age (7%, ...

Brief Summary: This retrospective cohort study investigated referral closures due to reidentification with birth-registered sex at the Child and Adolescent Health Service Gender Diversity Service in Perth, the sole provider of gender-affirming medical treatment for individuals <18 years in Western Australia. Out of 548 referral closures, 29 reidentified with birth-registered sex. Only 2 did so after having started medical treatment, constituting 1.2% (95% CI, 0.1%-4.4%) of...
