Introduction: Achieving/maintaining effective hormone suppression is fundamental in treating Central Precocious Puberty(CPP). CPP patients are vulnerable to late dosing as they cannot self-administer and require clinic/hospital visits for injections, currently exacerbated by COVID-19. In children, the hypothalamic-pituitary-gonadal axis may rebound faster than elderly oncology patients, so hormone escapes are possible with late dosing. Additionally, the stimul...

Background: Severe diazoxide unresponsive hyperinsulinism (DUHI) is most often caused by autosomal recessive variants in the KATP channel genes. Because of the limited medical treatments available, many patients are treated with 98% pancreatectomy. This results in a high rate of diabetes by the age of 15 years. Many centers now try to avoid surgery to prevent the inevitable transition to post-surgical diabetes.Objectives:</strong...

Background: Pseudohypoparathyroidism (PHP) is a rare group of disorders characterised by end-organ resistance to parathyroid hormone (PTH), and possibly TSH, with or without features of Albright’s hereditary osteodystrophy.Case presentation: A 14-year-old boy presented with fatigue and spontaneous carpal spasms in association with a febrile viral infection. Past medical history was significant for an episode of asymptomatic hypocalcemia treated with...

Introduction: Neonatal diabetes mellitus (NDM) is a rare (1:300,000–400,000 newborns) but potentially devastating metabolic disorder characterized by hyperglycemia combined with low levels of insulin. Two main groups have been recognized, transient NDM (TNDM) and permanent NDM (PNDM).Objective: To describle clinical features and laboratory manifestations of patient with NDM and evaluate outcome of management.Subject and method...

Background: Transient neonatal diabetes mellitus (TNDM) is a rare form of diabetes mellitus that presents within the first 6 months of life with remission in infancy or early childhood. TNDM is mainly caused by anomalies in the imprinted region on chromosome 6q24; however, recently, mutations in the ABCC8 gene, which encodes sulfonylurea receptor 1, have also been implicated in TNDM.Objective and hypotheses: To describe clinical features and lab...

Background: Neonatal diabetes mellitus (NDM), either transient (TNDM) or permanent (PNDM), is a rare form of monogenic diabetes, and usually presents in the first 6 months of life.Objective and Hypotheses: To describe the clinical characteristics and molecular genetics of a large Turkish cohort of NDM from a single centre.Method: NDM patients presenting to Diyarbakır Children State Hospital between 2010 and 2013 were prospecti...

Growth hormone (GH) is commonly used during childhood to treat short stature in Silver-Russell syndrome (SRS), but final height and long-term body mass index (BMI) data are limited.Objective: To evaluate height and BMI in older individuals with molecularly confirmed SRS and compare those previously treated with GH to those untreated.Methods: Growth data on individuals aged ≥13 years with SRS were evaluated from UK, French and...

Background: Genetic causes of central precocious puberty (CPP) has been increasingly recognized, extending our knowledge of the triggering factors of human pubertal timing. Distinct etiologies remain to be elucidated in sporadic and familial cases. Methyl-CpG-binding protein 2 (MECP2) is a chromatin-associated protein that can activate or repress gene transcription, playing a role in neuronal maturation. It is encoded by MECP2 gene located at chromoso...

Beckwith Wiedemann syndrome (BWS) is a rare overgrowth disorder characterised by macroglossia, exomphalos, lateralised overgrowth, organomegaly, hyperinsulinism, and an increased risk of embryonic tumor during early life. In about 80% of BWS cases, molecular defects are identified at the imprinted 11p15.5 region which contains the IGF2 and the CDKN1C genes (most patients show methylation defects at either imprinting control region IC1 or IC2, or paternal unip...

Background: Loss of function mutations in SGPL1, a key component of sphingolipid metabolism, are associated with accumulation of sphingolipid intermediates giving rise to a multisystemic disease incorporating primary adrenal insufficiency (PAI) and progressive renal and neurological disease. Sphingolipids are implicated in mitochondrial apoptosis via induction of mitochondrial outer membrane permeabilization, cytosolic release of inter-membranal cytochrome c and activ...
