Background: Costello syndrome may be associated with Hyperinsulinaemic Hypoglycaemia (HI), but this is usually a mild medically-responsive form.Objective and hypotheses: To describe the clinical characteristics, biochemical findings and challenging management of a case of Costello syndrome with severe HI.Method: Review of the patient’s medical records.Results: Male, born to non-consanguineous healthy par...

Background: Isolated GH deficiency (IGHD) may be due to several different causes. Mutations in the GHRH receptor (GHRHR) gene are a relatively rare cause of IGHD.Objective and hypotheses: To understand the molecular cause of severe short stature in a large highly consanguineous family with IGHD.Method: Affected patients were evaluated for GH secretion and other anterior pituitary function. Anterior pituitary size was measu...

Background: Congenital hyperinsulinism (CHI) causes severe hypoglycaemia in children, due to dysregulated insulin secretion from pancreatic β-cells. Glucagon, secreted from the pancreatic α-cells, is critical for blood glucose homeostasis. Somatostatin is secreted by Δ-cells of the islets and by extraislet neuroendocrine cells. Exogenous somatostatin potently inhibits insulin and glucagon release from pancreatic islets. Under normal physiological conditions, low...

Background: Congenital hyperinsulinism (CHI) is the most common cause of persistent hypoglycaemia in the neonatal period, characterized by unregulated insulin secretion by pancreatic β-cells. In addition to medical therapy, frequent feeding to prevent hypoglycaemia is one of the most important aspects in the management of CHI.Objective and hypotheses: To identify the number of patients with CHI who have associated feeding difficulties and determine ...

Background: Autoimmune polyglandular syndrome type 3 (APS3) comprises a wide spectrum of autoimmune endocrine disorders other than adrenal insufficiency. It includes the association of autoimmune thyroid disease (ATD) with type 1 diabetes (T1D) which is known as APS3 variant (APSA3v). Genes linked to possible joint susceptibility for APS3v have been reported in few cases. We report a 10-year-old girl with Graves’ disease (GD) who developed T1D after 6 years of the diagnos...

Introduction: We report the first known case of a child with mosaic Turner syndrome (TS) with ring X chromosome abnormality and Kabuki syndrome (KDM6A deletion) presenting with hypoglycaemia secondary to severe GH deficiency. Ring X Turner’s mosaic have the XIST locus, so the chromosome is inactivated, however the KDM6A gene deletion associated with Kabuki syndrome escapes X-inactivation as it is falls below the threshold required to manifest inactivation. This r...

Background: Hyperinsulinaemic hypoglycaemia (HH) has two main histological subtypes: diffuse and focal. Diffuse HH are most commonly due to recessive or dominant ABCC8/KCNJ11 mutations. Focal HH results due to somatic loss of the maternal 11p allele involving the ABCC8 and KCNJ11 region in patients with paternally inherited ABCC8 or KCNJ11 mutation.Aim: To molecular characterise a novel non-stop KCNJ11</em...

Background: Vitamin D dependent rickets type I (VDDR1) is an autosomal recessive disorder caused by mutations in the 25-Hydroxyvitamin-D3 1-α-hydroxylase gene(CYP27B1).Objective and hypotheses: To evaluate clinical characteristics and molecular genetic analysis of the pediatric patients with VDDR1 who were being followed at Diyarbakir Children’s State Hospital, Turkey.Method: VDDR1 diagnosis was consid...

Background: Persistent hyperinsulinaemic hypoglycaemia (HH) of infancy (PHHI) is a rare condition which presents with severe hypoglycaemia during the neonatal period. For medically unresponsive forms of diffuse HH, subtotal pancreatectomy was previously the only treatment option, with the potential consequences of recurrence of hyperinsulinism, diabetes mellitus and exocrine pancreatic insufficiency. The novel use of sirolimus treatment was recently reported in four infants wh...

Introduction: Since diabetes mellitus is one of the major non-communicable diseases, therefore it is important taking this subject in some details during the undergraduate medical course, to prepare the students for recognizing the disease and understanding its management. In Sultan Qaboos University, the medical students go through a pre-internship training period, immediately after their final year of clerkship and just before starting their internship.<...
