Introduction: The molecular aetiology of familial glucocorticoid deficiency (FGD) is very heterogeneous. A recent report of a genetic variant in TXNRD2, the gene encoding thioredoxin reductase Type 2, in a South Asian kindred with FGD suggests that the maintenance of redox balance may be critical for adrenocortical function. We present the second report of an individual from another south Asian family harbouring a different pathological variant in <em...

Background: Insulin Tolerance tests (ITT) have long been considered the gold standard for dynamic function testing of the hypothalamo-pituitary-adrenal (HPA) axis. Sub-optimal cortisol responses during an ITT in children may be found in children during ITT without a previous clinical suspicion of Adrenal insufficiency (AI). It is not clear what the clinical significance of this is and whether all of these children require formal synacthen testing.<p class=...

Background: Complication rates following hypospadias surgery are variable and given that hypospadias may be associated with a genetic or an endocrine condition, hypospadias outcome may depend on several clinical factors that require exploration.Aim: To perform a systematic review of cases of hypospadias operated at one tertiary centre to identify clinical determinants of optimal outcome.Methods: Retrospective review of clinical rec...

Introduction: Among Disorders of Sex Development (DSDs), XY DSD, represents the most challenging group in terms of identifying a diagnosis.Objectives: The aim of the study was to determine the prevalence of biochemical and molecular genetic tests in a cohort of boys with XY DSD and to collate the phenotypes of patients with results of laboratory investigations and presence of associated abnormalities.Methods: New and existing cases...

Background: Calculation of a urinary steroid metabolite ratio (uSMR) may be a useful method of improving diagnostic yield when investigating disorders of steroid hormone synthesis. Our aim was to investigate the range of uSMR in children with suspected disorders of steroid hormone synthesis.Methods: Ten ratios were calculated on steroid metabolite data analysed by GC-MS in urine samples collected between 2008 and 2010 from 94 children who were undergoing...

Introduction: Hypoglycemia is the most common acute complication in T1D. It has ominous symptoms and it is potentially fatal. Parents of infants with T1D are instructed in how to avoid, detect and manage these episodes. However, it is well known that many parents develop fear of hypoglycemia (FoH) which may lead to phobic avoidance behaviors such as permanent hyperglycemia and anxiety, losing optimal metabolic control. We aimed to explore how parenting stress ...

GR and GT are diamniotic monochorial preterm twins (32 GA), both AGA (GR: W -1 SDS, L -1.5 SDS; GT: W and L 0 SDS), with normal karyotype and array-CGH on amniotic fluid, with no major complications associated to prematurity. At birth GT presented bilaterally cryptorchidism associated with micropenis, GR presented normal male genitalia. In the first year of life a severe growth deceleration in length (from -3SDS to -5 SDS) was observed, mainly after six months of life in both ...

Background: Congenital hyperinsulinism (CHI) is a heterogeneous group of disorders, characterized by hypoglycemia due to inappropriate insulin secretion. Despite huge progress in understanding the pathophysiology of CHI, its etiology remains unknown in about 30% of cases.Aim: To perform whole-exome sequencing in patients with CHI.Results: A total of 314 patients with congenital hyp...

Introduction: The degree of consistency between the findings from next generation sequencing (NGS) and detailed endocrine assessment is unclear in boys with XY DSD.Objectives: Examine the range of endocrine and molecular genetic variation in boys undergoing evaluation for XYDSD.Methods: Boys with XYDSD who were evaluated in Glasgow from 2016 to 2018 were included. Sequence variants...

Introduction: Advances in diagnostic capability in the field of DSD hold great promise but need a regular review.Objectives: To study the range of endocrine and molecular genetic variation in a group of boys undergoing investigation for XY DSD.Methods: 157boys with median age of 0.9yrs (range,0,18) evaluated by the DSD Diagnostic Board in Glasgow from 2016to 2021 were included. Seq...
