Background: Unlike term neonates, known to exhibit a physiological pseudohypoaldosteronism, very preterms (VPT) display a high sodium waste at birth with partial aldosterone deficiency. This context, combined with a low aldosterone/renin ratio is highly suggestive of a defect in mineralocorticoid biosynthesis.Objectives and hypotheses: To investigate mineralocorticoid and glucocorticoid pathways in newborns, and to clarify the impact of prematurity upon ...

Background: Several studies have described ethnic differences in HbA1c. Non-Caucasian patients have been found to have an higher HbA1c than the Caucasian ones. These differences have often been attributed to disparities in access to medical care or quality of the care.Objective and hypotheses: Differences in Hba1c among the ethnicities could be related not only to mean glycaemia. The aim of our study was to observe if, at the same level of mean glucose, ...

Background: Pseudohypoaldosteronism is a rare condition of renal or systemic resistance to aldosterone, divisible into separate clinical presentations, each with a distinct physiological and genetic basis. Transient pseudohypoaldosteronism is a secondary form, characterised by reduced glomerulofiltration rate. It has been described in infants with obstructive uropathy and urinary tract infections.Method: We present five cases, presenting in infancy with ...

Background: Polycystic ovary syndrome (PCOS) is a common reproductive endocrinopathy in women of childbearing age, affecting 5–10% women in this age group. Its suggestive cardinal features are hyperandrogenism, ovulatory dysfunction and/or polycystic ovary appearance. The diagnostic gold standard tool is pelvic ultrasound (PUS) which may be limited in overweight and obese adolescent girls.Objective and hypotheses: To evaluate the contribution of pel...

Background and Aims: Hypoglycaemia is a life-threatening risk for many patients and prevention is individualised and complex. Continuous Glucose Monitoring (CGM) shows promise but current accuracy is insufficient for acute hypoglycaemia detection and data review services are complex and generic. Machine Learning is increasingly used but ignores weekly hypoglycaemia patterns and behaviour change and thus has demonstrated no real-world reduction in hypoglycaemia...

Background and Aims: In patients with congenital hyperinsulinism (CHI), recurrent hypoglycaemia can lead to longstanding neurological impairments. At present, glycaemic monitoring is with infrequent fingerprick tests; a practice which can miss hypoglycaemic episodes between tests. Continuous glucose monitoring (CGM) is a promising alternative method which has the utility to identify risk and patterns of hypoglycaemia. Although CGM is well established in type 1...

Background: Primary ovarian failure is (POF) characterised by primary amenorrhoea or early menopause in females. Minichromosome maintenance 10 (MCM10) is a gene involved in DNA damage repair, DNA replication and chromatin formation has received attention as a potential genetic etiology for neoplastic disease. Drosophila with mutated MCM10 have subfertility and dysfunction in female germline development. In humans, biallelic mutations of the MCM10 causes NK cel...

Introduction: Idiopathic intracranial hypertension (IIH) is a rare neurological condition characterized by raised intracranial pressure (ICP) in the absence of hydrocephalus, brain parenchymal lesion, vascular malformation, or central nervous system (CNS) infection. Hyperthyroidism is a rare but known cause of raised ICP in children and adults, with only a few case reports in the paediatric population. We describe a 7-year-old boy with IIH associated with hype...

Background: First line treatment for thyrotoxicosis is thionamide (TA) antithyroid drug therapy. The TA used is usually Carbimazole in the UK. TA can be administered in a relatively large 'blocking' dose that prevents endogenous thyroid hormone synthesis, requiring thyroid hormone replacement (block and replace or BR), or in a smaller dose that renders the patient euthyroid (dose titration or DT). The American Thyroid Association (ATA) recommends DT be...

Introduction: Osteopetrosis (OP) is a rare genetic disorder that is characterized by abnormal osteoclast function resulting in dense bones and marrow failure. The only definitive cure for OP is stem cell transplantation (SCT). Hypercalcemia is a well described complication in children with OP undergoing SCT. This study describes the calcium profile and treatment modalities used to maintain normocalcemia in children with OP undergoing SCT.<p class="abstext"...
