Background: Being born small for gestational age (SGA) has been associated with a reduction in health-related quality of life (HRQoL) and more problem behaviour. Growth hormone (GH) treatment, which leads to a significant improvement in adult height (AH), improves HRQoL and decreases problem behavior in SGA children. However, such results are very limited in SGA adults who were treated with GH during childhood.Objective:...

Introduction: Following the onset of the COVID-19 pandemic in spring 2020, the European Registries For Rare Endocrine Conditions (EuRRECa), which is a collaboration between Endo-ERN, ESPE and ESE provided the possibility for registration of cases. Obesity is a risk factor for severe COVID-19 disease course in adults. In children and adolescents, COVID-19 disease course is much milder, but has also been identified as risk factor. As rare genetic obesity disorde...

Introduction: Boys born small for gestational age (SGA) often have undermasculinized genitalia. Little is known about the pubertal development and gonadal function on a longer-term in this specific group of males.Aims: To determine the (pubertal) development and long-term urological and endocrine outcome of undermasculinized boys born SGA compared to undervirilized boys born appropriate for gestational age (AGA).<p c...

Summary Answer: Most primordial/primary oocytes were found to have a 46,XX karyotype. Chromosome patterns of the ovarian cells were different from that observed in other tissues.Background: TS is a chromosomal condition associated with partial or complete absence of one of the two X-chromosomes. Females with TS have a limited reproductive lifespan due to an accelerated loss of germ cells. It has been hypothesized that vi...

Background: Excessive gain in fat mass (FM) during the first months of life, known as the critical window for adiposity programming, is associated with an increased risk for adiposity and cardiovascular diseases in later life. Early life nutrition (breastfeeding or formula feeding) might influence body composition (FM and fat free mass (FFM)) development in early life.Aims: To investigate differences in sex-specific long...

The Polycomb Repressive Complex 1 (PRC1) represses gene expression through CBX2, which binds to H3K27me3 and promotes chromatin expression. Recently, CBX2 has been shown to function in testis-formation by directly repressing Wnt4's downstream target, Lef1, in Sertoli cells rather than positively controlling Sry expression, as previously thought. Here, we describe two new cases carrying missense mutations in CBX2. The first is a female with 46,XY ...

Introduction: Hormonal deficits are well known complications after allogeneic human stem cell transplantation (alloHSCT) in childhood and treated according to existing guidelines. It is assumed that bone mass and strength accrual during puberty is also often impaired, due to toxic therapy and prolonged inactivity, but data on bone geometry and strength are scare in this particular group.Objective/Patients and Methods: Cr...

Resistance to thyroid hormone due to mutations inactivating thyroid hormone receptor-Beta occurs in one in 40,000 individuals and can arise de novo or be inherited, generally in a dominant fashion. Clinical manifestations are widely variable and include failure to thrive in infancy. The biochemical diagnosis is usually straightforward: high serum fT4 and non-suppressed TSH.We report two brothers who both inherited the known c.728G>A, p.R24...

Background and Aims: It has been postulated that the first 3 months of life are critical for programming of adult metabolic health. We investigated if Body Mass Index (BMI) and Fat Mass percentage (FM%) in early life tracks to 5 years of age and if feeding mode influences tracking.Methods: In 268 term born, healthy infants from the Sophia Pluto cohort (161 boys ), BMI was determined at 3 and 6 months, 2 and 5 years o...

Background: Neonatal cortisol assessment is indicated in suspected adrenal insufficiency. Clinical presentation includes: low blood glucose, low blood pressure, ambiguous genitalia, electrolyte abnormalities, midline abnormalities.Aims: Review the trends, outcomes and associations of cortisol assessment in neonates within our Trust between 2012-2018.Objectives: Review:<p class=...
