Introduction: Patients carrying homozygous IGF1 loss-of-function mutations are extremely rare and show severe pre- and postnatal growth failure, microcephaly, developmental delay, retrognathia and sensorineural deafness. Heterozygous variants in IGF1 appear to be more common in short stature, but only few cases have been reported in detail. Therefore, clinical features and growth response to recombinant human growth hormone (rhGH) therapy are...

Introduction: The ESPE e-Learning web portal is a free, globally accessible online tool to enhance learning in Paediatric Endocrinology and Diabetes. Since August 2022, the e-learning content includes 30 accredited hours of ESPE/ISPAD e-learning Continuing Medical Education (CME) courses with ten core modules each in Paediatric Endocrinology, Paediatric Endocrinology in Resource Limited Setting (RLS) and Paediatric Diabetes. The CME modules were created by wor...

Introduction: West Midlands Complications of Excess Weight (CEW) service covers a large geographical area with high levels of ethnic diversity with over 40% of people living in the most deprived decile (Index of Multiple Deprivation -IMD). We aim to investigate markers of deprivation in our CEW cohort.Methods: Retrospective review of patients seen in our CEW service between July 2021 and August 2023. Data was collected f...

Introduction: Diagnosis of growth hormone (GH) deficiency is known to have unreliable results, especially due to low specificity of GH stimulation tests. Children diagnosed with GH deficiency (GHD) therefore form a heterogeneous group with a cause frequently unrelated to GH secretion or function. On the other hand, children with extremely low maximal stimulated GH concentrations (<3 ug/L) are believed to have “real” GH deficiency (GHD). However,...

Background: P450 oxidoreductase (POR) is a co-factor critical for the function of type 2 microsomal cytochrome P450 enzymes. POR deficiency (PORD) results in a rare form of congenital adrenal hyperplasia, with combined attenuation of CYP21A2 and CYP17A1 steroidogenic enzymes. It is characterised by combined deficiencies of glucocorticoids and androgens postnatally. Differences in sex development can arise in both sexes due to antenatal activation of the altern...

Background: Current Turkish growth reference charts based on anthropometric measurements of individuals with high socioeconomic status in Istanbul in 1989-2002 (TK2002) had shown an increase of mean adult height (1.4 and 2.7 cm in males and females) compared with 1978. Given recent improvements in nutrition, hygiene and access to preventive health services, we hypothesized that this positive secular trend may continue.Methods:</s...

Background: N-methyl-D-aspartate receptors (NMDARs) are ionotropic glutamate receptors that are widely expressed in the CNS where they play an important role in neurotransmission and cell viability and serve as drug targets for the treatment of neurodegenerative disorders.Objective and hypotheses: Much less is known about the role of pancreatic NMDARs. Since neurons and pancreatic islets have many features in common, we hypothesiz...

Introduction: Health related Quality of Life (QoL) outcome is used as an argument when continuation or stopping growth hormone (GH) treatment is considered in patients with idiopathic isolated growth hormone deficiency (IIGHD) who tested GH sufficient in mid-puberty (inclusion moment for this study).Aim: To assess potential differences in QoL between patients with IIGHD who discontinued treatment and those who continued ...

Background: Subtle phenotypic differences have previously been described among children with varied genetic subtypes of Prader-Willi syndrome (PWS) – 15q11-q13 paternal microdeletion, maternal uniparental disomy (mUPD), and rare imprinting center defects. The MKRN3 gene, located on 15q11.2, is a master regulator of pubertal initiation and is a candidate gene for abnormal pubertal development in PWS.Objective and hy...

Background: 5α-reductase type 2 deficiency (SRD5A2) is a rare cause of 46,XY DSD. Consensus guidelines on sex of rearing assignment at birth favours male gender. Typically undervirilised genitalia at birth virilise variably at puberty, posing gender identity challenges.Aim: We describe relevant data on clinical phenotype, hormonal and molecular workup and gender preference in patients with SRD5A2 deficiency from a ...
