Background: Bisphosphonates have been used for treatment of bone fragility disorders for over 25 years to increase bone mineral density (BMD). Anecdotally, bisphosphonate-treated Osteogenesis Imperfecta (OI) has a different trajectory to the natural history of untreated OI, with minimal published evidence to support this clinical observation.Aims: To describe functional outcomes of a cohort of adults with OI, stratified according to severity and treated ...

We report three cases of neonatal diabetes from Kazakhstan, Almaty with the KCNJ11 gene mutation who were successfully switched from insulin to sulphonylurea treatment and 1 case of insulin (INS) gene mutation that presented as permanent insulin dependent neonatal diabetes.Case 1: An 1 month old girl presented with elevated glucose level, dehydation, ketoacidosis and was treated with Insulin. HbA1c at diagnosis was 10%. Heterozygous missense mut...

Background: It is important to make correct diagnosis of monogenic diabetes or MODY in children. Most of the patients are misdiagnosed with diabetes type 1 or type 2 and undergo unnecessary treatment with insulin or oral medications. We report first 1 case of MODY with heterozygous mutation in HNF1A gene when Insulin treatment was changed to sulphonylurea treatment and 1 case of compound heterozygote of glucokinase (GCK) gene and HNF1A gene mutations.Cas...

Background: Single nucleotide polymorphisms (SNPs) within the promotor and 5’UTR of the transcriptional factor, ZBTB38, are associated with adult height and idiopathic short stature although their precise auxological effects have not previously been described. In addition, the molecular mechanisms through which ZBTB38 affects growth have not been fully elucidated but potential downstream mediators are suggested to include MCM10 or IGF2.Objectives: <...

Background: Prolactinomas are relatively rare during childhood, with an incidence of 0.1 per million. Children with hyperprolactinaemia have widely varied presentations depending on age, sex, and tumour size. Whilst adults typically present with galactorrhoea or hypogonadism, children tend to present with pubertal delay and growth issues.Objective and hypotheses: Poorer surgical outcomes have been reported in children with macroprolactinomas compared to ...

Background: Steroidogenic factor 1 (SF1), encoded by the gene NR5A1, is a member of the orphan nuclear receptor superfamily and important regulator of gonadal and adrenal function. Variations in SF1 lead to a spectrum of conditions including 46,XY DSD, hypospadias, adrenal insufficiency, male factor infertility, and primary ovarian insufficiency. Inheritance patterns can be complicated (e.g. de novo dominant, sex-limited dominant, and autosomal recessive). In...

Background: Glycogen-storage disease type VI (GSD VI) is an autosomal recessive disorder due to deficiency of the liver isoform of phosphorylase resulting in abnormal accumulation of glycogen. Patients typically present in early childhood with growth retardation, hepatomegaly, hypoglycaemia and ketosis. Ketotic hypoglycaemia is a relatively common diagnosis (of exclusion) in children presenting with hypoglycaemia.Case: A 3-year-old girl presented with an...

Introduction: Peroxisomal biogenesis disorders - Zellweger Syndrome Spectrum (PBD-ZWS) are rare disorders involving multiple systems including the central nervous system, adrenals, liver and skeleton but hyperinsulinism is not a recognized association. We present a child with PBD-ZWS due to a novel mutation in PEX1 who developed hyperinsulinaemic hypoglycaemia (HH).Case report: A 7 month old boy presented with recurrent hypoglyc...

Synacthen tests are used widely in paediatric practice for diagnosis of AI. The standard dose test may be more specific and low dose test (LDSST), more sensitive. The LDSST requires dilution of commercially available Synacthen, which may result in unreliable dosing and over diagnosis of AI.Aim: To determine the prevalence of AI requiring treatment with hydrocortisone (a) daily (peak cortisol <350nmol/l) (b) on sick days only (peak co...

Background: Rapid-onset obesity with hypoventilation, hypothalamic dysfunction, autonomic dysregulation (ROHHAD) is a rare syndrome associated with high morbidity and mortality presenting with rapid onset of obesity in early childhood. An immune-inflammatory aetiology has been postulated; however, the immune profile is not well described.Case report: We report the case of a five-year-old female who presented in respirato...
