Background: Age at onset of puberty exhibits a remarkable variation mirroring nutritional, environmental, socioeconomic and genetic factors. While large genome-wide association studies identified more than hundred genetic loci associated with age at menarche in girls, knowledge on loci associated with age at pubertal onset in boys is sparse. FSHB/FSHR genetic variants have been shown to affect pubertal timing in girls and reproductive parameters in men.<p class="a...

Background: The anogenital distance (AGD) is considered a valid marker of altered androgen action in utero. Recently, reduced AGD has been shown in males with hypospadias, cryptorchidism, reduced semen quality and infertility. It has also been proposed as a new marker to be used by clinicians when managing patients with Disorders of Sex Development. However, little normative data exist and measurement methods vary.Objective and hypotheses: We established...

Background: Children and adolescents with chronic conditions are at increased risk of secondary osteoporosis. In adult patients, long-term anticoagulation (LTA) including Vitamin K antagonist (VKA) treatment is associated with lower bone mineral density and hip fractures. In children and adolsescent, risk factors for impaired skeletal health and the role of LTA on bone metabolism during the vulnerable phase of linear bone growth remain poorly defined.<p cl...

Background: Genetic defects in the Wnt signaling pathway lead to early-onset osteoporosis (EOOP). Romosozumab is a monoclonal antibody against sclerostin, an inhibitor of the Wnt/ß-catenin pathway. Romosozumab has shown great efficacy in adult osteoporosis, however its effect in patients with Wnt-related EOOP is unknown. In monoallelic loss-of-function WNT1 mutations, romosozumab could potentially stimulate the defective Wnt signaling pathway an...

Background: Linear growth during spontaneous puberty contributes approximately 20% to adult height in healthy subjects. The impact of gender-affirming hormone therapy (GAHT) on final height in transgender adolescents is sparsely studied.Aim: We aimed to investigate the growth and final height of Danish transgender adolescents.Methods: Our national cohort of transgender adolescents ...

Background: Hypercalcaemia has various etiologies and treatment is often challenging. Therapeutic options include aggressive fluid management, loop diuretics and antiresorptive drugs. Since both hypercalcaemia and bisphosphonates can cause acute kidney injury (AKI), bisphosphonates are not recommended in patients with renal impairment. Denosumab, an antiresorptive human monoclonal antibody, is not associated with AKI and offers a temporary treatment option. Ho...

Background/Aims: Magnetic resonance imaging (MRI) is used to investigate the etiology of growth hormone deficiency (GHD). There is a close relationship between structural changes in the pituitary gland and clinical status.We aimed to investigate the relationship between MRI findings and clinical symptoms and treatment response in children with GHD.Methods: The study was conducted in nine Department...

Background and Aims: Klinefelter syndrome (KS) is the most common chromosomal abnormality in men, but because of its highly variable phenotype and clinical unawareness, it remains largely under-diagnosed. Cardinal features include tall stature, gynecomastia, hypergonadotropic hypogonadism, azoospermia and infertility. Learning and behavioral problems are also common. Testosterone replacement therapy (TRT) helps to prevent or ameliorate many of the comorbiditie...

Background: Growth hormone (GH) treatment is indicated for children who are born small for gestational age (SGA) and fail to achieve sufficient catch-up growth during infancy and remain short throughout childhood.Aims: To evaluate the effect of GH treatment in a large, multicentric, Portuguese SGA children cohort and to analyze for correlation between GH treatment response and clinical factors.<str...
