Background: FOP is an ultra-rare, severely disabling genetic disorder characterised by progressive heterotopic ossification. The median age at diagnosis is 5 years and patients are supported by multiple specialties. We describe normal long bone growth changes and incidence of bone abnormalities in participants with FOP aged <18 years in a 3-year, prospective, global NHS (NCT02322255).Methods: Individuals with FOP age...

Background: Thyroidectomy is a definitive treatment option in some benign thyroid disorders and the definitive treatment option for thyroid cancer. As postoperative mortality is extremely rare data on postoperative complications and long-term health consequences are important.Objective: To evaluate the frequencies of short- and long-term complications, and their risk factors in pediatric patients (0-18 years) who underwent a thyroidectomy in a tertiary c...

Introduction: Lockdown measures following the COVID-19 pandemic are shown to have greatly affected lifestyle behaviours and health-related quality of life (HRQoL) of children. The impact on children with severe obesity has not yet been described. Aim of this study was to investigate the impact of COVID-19 lockdown on eating behaviours, physical activity (PA), screen time, and HRQoL of children (including adolescents) with severe obesity....

We introduce the ReTRIACt Trial (NCT05579327) of tiratricol (Triac) for MCT8-deficiency, a rare X-linked disease resulting from disordered thyroid hormone transport and characterized by profound neurodevelopmental delay and features of chronic peripheral thyrotoxicosis. The ReTRIACt Trial aims to verify the effects of tiratricol observed in previous studies. It is a double-blind, randomized, multicenter, placebo-controlled study to evaluate the effects of tiratricol discontinu...

Introduction: Children with cancer are at increased risk of endocrine complications, especially children with a brain tumor. One of these late effects includes bone disorders (ranging from low bone mineral density (BMD) to osteoporosis). Children with a suprasellar Low Grade Glioma (LGG) may be especially at risk for bone problems due to exposure to multiple treatment modalities, hypothalamic dysfunction and/or decreased mobility in combination with vision los...

Three patients from two unrelated families in Malta; one consanguineous (siblings: Patient 1, male and Patient 2, female) and one non-consanguineous (Patient 3, male), manifested hypogonadotropic hypogonadism with delayed puberty, intellectual disability, scoliosis, and ataxia with cerebellar hypoplasia on MRI. GnRH tests revealed low peak LH and FSH concentrations in the patients: Patient 1; LH 2.3 IU/L, FSH 4.4 IU/L (14.3y), Patient 2; LH 3.6 IU/L, FSH 6.4 IU/L (12.5y), Pati...

Congenital hyperinsulinism (CHI) is a life-threatening disease and manifests in the majority of cases in the first days after birth. Based on the distribution of affected cells, focal CHI forms are distinguished from diffuse CHI forms. Focal forms occur in most cases due to a paternally inherited heterozygous mutation in a subunit of an ATP sensitive potassium channel (ABCC8, KCNJ11). Within the diagnostic setting, focal forms can be visualized by 18F DOPA PET scan, as a marke...

Background: Recently, patients with severe obesity have been described due to functional leptin deficiency. This new entity is characterized by high immunoreactive levels of circulating leptin (Lep), but a reduced bioactivity of the hormone due to defective receptor binding (N Engl J Med 2015;372:48–54). Since these patients can be successfully treated with human recombinant leptin (metreleptin), a diagnostic tool to detect functional leptin deficiency is needed.<p cl...

Objectives: Compared to the US, prevalence rates of T2DM in obese children are significantly lower in European countries. Data from cohorts of obese children living in the US suggest a concurrent worsening of insulin sensitivity and ß-cell function over the spectrum of glucose tolerance. If these results can be applied to European populations is currently unknown.Methods: A combination of our novel method for mathematical modelling ...

Background: Congenital adrenal hyperplasia (CAH) and long-term glucocorticoid treatment may be associated with an increased risk of developing cardiometabolic sequelae such as abnormal glucose homeostasis, hyperlipidaemia, hypertension, cardiovascular (CV) disease, obesity and osteoporosis.Objectives: To study the current practice amongst expert centres for assessing cardiometabolic outcomes in adult patients with 21-hyd...
