Background: Adrenal cortical carcinoma (ACC) in children is rare and aggressive, with the mainstay of treatment being surgical resection, although there have been recent improvements in outcomes with chemotherapy. Further characterisation of the presenting features and biochemical markers are needed to support earlier diagnosis. Refractory hypertension related to high cortisol concentrations prior to surgery, and post-operative decrease in cortisol can be chal...

Introduction: Multiple endocrine neoplasia 2B (MEN2B) is a rare cancer syndrome primarily caused by the M918T (95%) and A883F (<5%) germline mutations in the REarranged during Transfection (RET) proto-oncogene. Aggressive and early onset thyroid medullary carcinoma is the hallmark of the disease. Cure rates in M918T carriers who had thyroidectomy before and after 1 year of age were 83% and 15% respectively. More t...

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 ...

Introduction: Brain tumors are the most common solid neoplasm in children, and treatment often includes high-dose irradiation of the central nervous system (CNS). Although not universal, growth hormone deficiency (GHD) is a very common endocrine late effect after CNS irradiation in childhood. The consequences of GHD in adults are many e.g., reduced bone mineral density, fatigue, decreased lean body mass and adiposity, which implies that adults with severe GHD ...

Objective: Type 1 diabetes in childhood is associated with an increased risk of psychiatric morbidities. We investigated predictors and diabetes outcomes in a pediatric population with psychiatric comorbidities.Research Design and Methods: Nationwide pediatric registerbased study. Data from the Danish national childhood diabetes register (DanDiabKids) and The National Patient Register were collected (1996–2015) for this population-based study. We us...

Background: Recombinant human GH (rhGH) is normally administered as a daily s.c. injection. NNC0195-0092 is a reversible albumin-binding GH derivative developed with the aim of reducing clearance and thereby extending the exposure. It has previously been demonstrated that NNC0195-0092 is well tolerated in healthy subjects with the potential for once weekly administration.Objective and hypotheses: In this trial NNC0195-0092 was administrated subcutaneousl...

Background: Transgender adolescents may be treated with gender affirming hormone therapy (GAHT) consisting of gonadotropin-releasing hormone agonists (GnRHa) and cross-sex hormones. Limited data are available regarding the metabolic effects of GAHT in adolescence.Objective: To evaluate the lipid profiles and HbA1c in transgender adolescents after one year of cross-hormone treatment.Patients...

Background: X-linked hypophosphatemia (XLH) are rare inheritable disorders caused by excessive renal phosphate wasting manifesting as rickets in children and osteomalacia in adults. Osteoid accumulates due to the reduced mineralization rate. Based on previous histomorphometric bone biopsy studies it the impression that XLH is a low bone turnover disease. Very little is known about the level of bone markers in XLH and the effects of conventional medical treatment with oral phos...

Background: Alterations in the timing or expression level of players involved in sex determination and differentiation can cause disorders of sex development, gonadal dysgenesis and germ cell neoplasms later in life. The mitosis–meiosis switch is one of the first manifestations of female sex differentiation and we hypothesise that a conflict between meiosis-inhibiting (male pathway) and meiosis-inducing signals (female pathway) is one of the possible mechanisms for disrup...

Introduction: The diagnosis of a disorder/difference of sexual development (dsd) is an exceptional psychosocial situation. As the diagnosis is often made in childhood, the parents are the primary communication partners. In some cases, the impossibility of immediate sex determination of the child can be a traumatic experience with a negative impact on the relationship between the parents and the child, the couple and members of the entire family. It has been recommended by the ...
