Introduction: Septo-optic dysplasia (SOD) is characterized by a combination of midline forebrain, pituitary and eye abnormalities. We aimed to evaluate the clinical, neuroradiological and endocrine features of patients with SOD and multiple pituitary hormone deficiencies (MPHD).Design: Retrospective data were collected from 76 patients with SOD and 26 with MPHD, followed at a single centre. SOD patients were divided into two groups: i) with pituitary hor...

Introduction: To date, few cases with both congenital hypopituitarism (CH) and hyperinsulinaemic hypoglycemia (HH) have been reported in the literature. We now report a cohort of 12 cases with CHI associated with HH.Clinical Phenotype: An association between congenital hypopituitarism (CH) and hyperinsulinaemic hypoglycemia (HH) was present in 12 patients (M:F 9:3). Mean age at diagnosis of HH was 0.9 months, whereas mean age at diagnosis of CH was 2.0 y...

Introduction: In congenital hyperinsulinism (CHI) hypoglycaemia results from a dysregulation of insulin secretion. We hypothesised that other pancreatic hormones may also be dysregulated in this condition.Objectives: To proof the applicability of Luminex Multiplex method to measure pancreatic hormones (insulin, C-peptide, glucagon, amylin and PP) in the paediatric age. To elucidate the fasting response of these hormones in children with different forms o...

Introduction: Isolated postprandial hyperinsulinaemic hypoglycaemia (PPHH) in the paediatric age has been exceptionally reported in the literature.Objective: To describe the clinical and biochemical characteristics as well as the management of a cohort of children with isolated PPHH followed at a single tertiary paediatric centre.Subjects and methods: Six children (three males) were collected. The clinical characteristics, diagnosi...

Introduction: Multiple pituitary hormone deficiency (MPHD) and septo-optic dysplasia (SOD) are well known causes of hypopituitarism, but children with optic nerve hypoplasia (ONH) may also be at risk of hormone and neurocognitive disturbances. Clinical and neuroradiological findings of these three related conditions are characterised in this study, aiming to understand their pathophysiology.Design: Data from 140 patients with hypopituitarism (MPHD, SOD) ...

Introduction: Post-prandial hyerinsulinaemic hypoglycaemia (PPHH) or dumping is a recognized complication of various gastric surgeries. There are very few paediatric case reports to confirm PPHH post esophageal repair. We here report two cases who presented with dumping syndrome after a variable time period post esophageal atresia repair and response to medications.Case 1: A 6 month old female diagnosed with Wolf-Hirschhorn syndrome, born at 38+3 weeks b...

Introduction: Cushing’s syndrome is a rare and life-threatening paediatric disease, the diagnosis of which can be challenging given its heterogeneous clinical presentation and the investigation results which are frequently inconclusive.Aim: To assess the reliability of the tests used for screening and for establishing the aetiology of Cushing’s syndrome.Design: We conducted a retrospective study analyzing cases of Cushing...

Introduction: Several previous case reports have described the use of the calcium-blocker Nifedipine for the treatment of hyperinsulinaemic hypoglycaemia (HH). These cases are a collection of transient/permanent forms of HH, with known/unknown genetics, where Nifedipine has been used either as monotherapy or in combination with other medications. There have been no previous reports of any systematic trial of Nifedipine use in patients with HH due to mutations in the ABCC8<...

Background: CHI is a cause of severe hypoglycaemia in children. Diazoxide (KATP channel agonist) is used as first-line treatment but is known to cause severe hypertrichosis and reduced appetite in children. Diazoxide unresponsive CHI us treated with daily octreotide subcutaneous injections (3–4 times/day).Objective and hypotheses: To evaluate the efficacy, safety and pharmacokinetics of long acting Somatostatin analogue (Lanreotide) thera...
