Context: In focal congenital hyperinsulinism (CHI), localized clonal expansion of pancreatic β-cells causes excess insulin secretion and severe hypoglycemia. Surgery is curative, but not all lesions are amenable to surgery.
Objective: We describe surgical and nonsurgical outcomes of focal CHI in a national cohort.
Context: Meta-analyses report that the low dose short Synacthen test (LDSST) is more sensitive but less specific than the standard dose test for the diagnosis of adrenal insufficiency, and there are concerns regarding the accuracy of dosing in the LDSST.
Objective: Perform a retrospective, observational study to review the outcomes of LDSSTs performed in a tertiary endocrine service from 2008 to 2014 (N = 335) and 2016 to 2020 (N = 160), and examine for relationships between cortisol measurements and indication for testing, age and sex.
Methods: LDSST were performed by endocrine nurses.
Background: Noonan syndrome is an autosomal dominant condition with an incidence of 1:1000 to 1:2500. The disorder is associated with distinct dysmorphic features, cardiac anomalies, developmental delay and delayed puberty. Short stature is a recognised feature of Noonan syndrome.

Objectives Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disorder, caused by mutation in NF1. The condition is typified by the development of benign and malignant tumours in both the central nervous system and peripheral tissues. Isolated menarche is a sub-classification of incomplete isosexual precocious puberty typified by menarche in girls with no other features of pubertal development.

Although a biphasic phenotype of congenital hyperinsulinism in infancy followed by Maturity-Onset Diabetes of the Young (MODY) in later life has been established for HNF4A, the existence of a similar phenotype for a related MODY gene, HNF1A, is less clear. We describe two cases of congenital hyperinsulinism in association with dominantly inherited variants in HNF1A.

Various autosomal dominant heterozygous mutations leading to hyperinsulinemic hypoglycaemia (HH) have been described in adults and children (more than 3 years of age) but not in the neonatal period. Family 1: A small for gestational age (SGA) child born to a mother with gestational diabetes presented with persistent hypoglycaemia, was diagnosed with HH and responded well to diazoxide treatment.

Design: Retrospective cohort study.
Objective: To compare the efficacy, safety, and cost utility of continuous subcutaneous insulin infusion (CSII) with multiple daily injection (MDI) regimens during the first year following diagnosis of type 1 diabetes in children and young people.
Design: Pragmatic, multicentre, open label, parallel group, randomised controlled trial and economic evaluation.
Setting: 15 paediatric National Health Service (NHS) diabetes services in England and Wales.

Background There is limited data on adrenal function in the early days after birth in extremely premature infants. The relationship between plasma adrenocorticotrophic (ACTH) and cortisol hormone is central to the integrity of the hypothalamic-pituitary-adrenal (HPA) axis yet there are no studies examining this relationship in prematurity. Methods The aim of this study was to examine the relationship between early morning plasma cortisol and ACTH concentrations during the first 5 days after birth in infants born at less than 28 weeks' gestation and to identify any independent factors that determine plasma cortisol levels in these infants during extreme prematurity.

Beckwith-Wiedemann syndrome (BWS) can be associated with embryonal tumours and congenital hyperinsulinism (CHI). We present an infant with BWS who developed congenital hepatoblastoma and Wilms' tumour during infancy. The infant presented with recurrent hypoglycaemia requiring high intravenous glucose infusion and was biochemically confirmed to have CHI.
View Article and Find Full Text PDFBackground Congenital hyperinsulinism (CHI) occurs due to an unregulated insulin secretion from the pancreatic β-cells resulting in hypoglycaemia. Causative mutations in multiple genes have been reported. Phenotypic variability exists both within and between different genetic subgroups.
View Article and Find Full Text PDFBackground: The risk of developing long-term complications of type 1 diabetes (T1D) is related to glycaemic control and is reduced by the use of intensive insulin treatment regimens: multiple daily injections (MDI) (≥ 4) and continuous subcutaneous insulin infusion (CSII). Despite a lack of evidence that the more expensive treatment with CSII is superior to MDI, both treatments are used widely within the NHS.
Objectives: (1) To compare glycaemic control during treatment with CSII and MDI and (2) to determine safety and cost-effectiveness of the treatment, and quality of life (QoL) of the patients.
Background: Hydrocortisone is the preferred treatment for adrenal insufficiency in childhood. A small minority of children experience low cortisol concentrations and symptoms of cortisol insufficiency, poorly responsive to modifications in dosing. We speculated that treatment with modified-release hydrocortisone Plenadren may be beneficial in these selected patients.

The screening guidelines for TS suggest karyotype evaluation in patients presenting with short stature, webbed neck, lymphoedema, coarctation of aorta or ≥ two dysmorphic features. The aim of the study was to determine the age and clinical features at the time of presentation and to identify potential delays in diagnosis of TS.

With the development of new minimally invasive techniques for the treatment of HH, there is a need to reappraise the effectiveness and safety of each approach. We review the outcomes of HH patients treated surgically, utilizing intraoperative magnetic resonance imaging (IOMRI), by a team of Alder Hey NHS Foundation Trust tumour and epilepsy neurosurgeons since 2011.

There are no reports available regarding its use in patients with congenital hyperinsulinism (CHI). We have assessed the accuracy of FSL compared to the finger prick capillary blood glucose (CBG) over 2 weeks period in patients with CHI and evaluated the parents' experience of using FSL.

We describe the occurrence and higher prevalence of ketotic hypoglycemia (KH) in 5 children with transient CHI. Four children had required diazoxide to control the persistent hypoglycemia that was discontinued at a mean age of 11.

Homozygous mutations have been associated with short stature, skeletal deformities, and congenital heart defects. We describe for the first time a novel heterozygous splice site mutation in contributing to severe short stature, growth hormone (GH) deficiency, recurrent ketotic hypoglycaemia, facial dysmorphism, and congenital heart defects.

Congenital hyperinsulinism (CHI) is a disorder of unregulated insulin secretion despite hypoglycaemia that can occur in isolation or as part of a wider syndrome. Molecular diagnosis is unknown in many cases of CH and CHI.

Although testosterone usage in this group has not been shown to affect the final adult height, the effect on the first year height velocity has not been widely reported.
Objectives: The aim is to determine whether testosterone treatment improves the first year height velocity in boys with CDGP when compared to boys with CDGP who go through puberty spontaneously.
Background: De novo truncating and splicing mutations in the additional sex combs-like 3 () gene have been implicated in the development of Bainbridge-Ropers syndrome (BRPS) characterised by severe developmental delay, feeding problems, short stature and characteristic facial features.
Case Presentation: We describe, for the first time, a patient with severe short stature, learning difficulties, feeding difficulties and dysmorphic features with a novel compound heterozygous mutation in .Additionally the patient also has primary insulin like growth factor-1 (IGF1) deficiency.
Background: A baby girl was born at 39 weeks gestation to consanguineous Asian parents. From day 1 of life she had severe hypoglycaemia with an inappropriately elevated insulin concentration consistent with congenital hyperinsulinism (CHI), confirmed by the finding of a homozygous mutation in ABCC8 (encoding the sulfonylurea receptor 1).
Case Diagnosis/treatment: Urine organic acid analysis showed an incidentally elevated excretion of glycolate.
Background: Recent data indicates that adults with Down syndrome (DS) are at increased risk for cardiovascular disease (CVD) that significantly contributes to their morbidity and mortality. Although identification of cardiometabolic risk factors during childhood is desirable to design preventive interventions, the data on such risk factors in children with DS is scarce. The aim of this study was to study the cardiometabolic risk factors such as insulin resistance (IR), leptin and adiponectin concentrations, lipid abnormalities and leptin resistance in non-obese children with DS.
