Juvenile Paget's Disease: Evaluation of Novel Mutation and Treatment Response

Betul Kaygusuz Sare , Gokoglu Mustafa , Turan Serap

Introduction: Juvenile Paget's Disease(JPD) is an extremely rare disease of bone characterized by progressive painful bone deformities, fractures and increased bone turnover. Findings also include deafness, loss of vision, vascular calcification and aneurysm. Here, we report two siblings presented with recurrent fractures and diagnosed as JPD by very high alkaline phosphatase levels and radiographic findings. A novel homozygous mutation in the TNFRSF11B g...

Introduction: Genetic factors play an important role in determining individual susceptibility to weight gain and obesity. In the last few years, several genetic variants have been identified as monogenic forms of obesity. Among them, Leptin (LEP) and its receptor on hypothalamic neurons (LEPR) are key players in the regulation of body weight, food intake and energy homeostasis. Pathogenic variants in the LEPR gene cause severe childhood-onset obesity with an a...

Introduction: Increased frequency of Grave’s disease (GD) has been reported both in adults and youth during the COVID-19 pandemic. Aim: To compare the frequency of GD prior and during the COVID-19 pandemic.Methods: Retrospective analysis of children diagnosed with GD over the last 13 years in our Department.Results: A total of 22 children (31.8% boys) with a mean age of 10.55...

Challenges Experienced in Delivering Growth Hormone Therapy in Children's with Prader Willi Syndrome in Birmingham Children's Hospital.

Kollurage D Udeni Anuruddhika , Barrett Tim , Jayamanne B D W , Krone Ruth

Prader Willi Syndrome (PWS) is a rare neuro-genetic disorder inherited as a result of lack of expression in 15q11-13 gene and 70% are paternally inherited. Characteristic features are dysmorphism, behavioural problems, infantile hypotonia, short stature, hypothalamic dysfunction, hyperphagia and morbid obesity. The long-term morbidity and mortality depend on hypothalamic dysfunction and obesity. While multidisciplinary care is essential, growth hormone (GH) is a recognized...

Management of Hypoparathyroidism: Follow-Up of 20 Patients

Darcan Sukran , Ozcan Nurhan , Ozen Samim , Goksen Damla

Background: Hypoparathyroidism is a rare disease characterized by inadequate parathyroid hormone (PTH), resulting in hypocalcemia and hyperphosphatemia. Hypoparathyroidism can be transient, inherited, or acquired, and is caused by inability to synthesize or secrete PTH, abnormal parathyroid gland development, destruction of parathyroid tissue, or peripheral resistance to PTH.Methods: Medical records from 20 children and adolescents diagnosed with hypopar...

Continuous Glucose Monitoring and Hypoglycemia Unawareness in Children and Adolescents with Type 1 Diabetes

Demir Gunay , Ozen Samim , Cetin Hafize , Darcan Sukran , Goksen Damla

Background: Seeking strict normoglycemia in type 1 diabetes mellitus increases the risk of hypoglycemia, exposing to hypoglycemia unawareness. Hypoglycemia unawareness (HU) is defined as the occurrence of hypoglycemic symptoms directly without autonomic symptoms. This study is designed to determine the incidence of HU in children and adolescents with continuous subcutaneous glucose monitoring system and to assess the effect of structured education to improve awareness.<p c...

A Novel MC4R Mutation Associated with Infancy-Onset Obesity

Goksen Damla , Onay Huseyin , Ozen Samim , Ozkinay Ferda , Darcan Sukran

Background: The melanocortin-4-receptor gene (MC4R) is a key regulator of energy homeostasis, food intake, and body weight which has intensively been analysed in molecular genetic obesity research. MC4R dysfunction in humans causes hyperphagia, impaired satiety and obesity. Most patients are heterozygotes, with some reports of homozygotes and compound heterozygotes.Objective and hypotheses: A 2-year-old boy with progressive weight gain from infa...

A Case of Sjogren's Syndrome with systemic involvement combined with exacerbated hyperthyroidism improved after glucocorticoid treatment

Lee Donghyun , Sik Kim Heung , Yun Park So , Kang Seokjin

Background: Sjogren’s syndrome is a systemic autoimmune disease, and it is rare in pediatric population. Primary symptoms are dry mouth and dry eyes. However, it may present with systemic manifestations, involving lungs, liver, kidneys, vasculature, and blood. We report a case of Sjogren's syndrome with systemic involvement in a child with Graves' disease.Case report: A 9-year-old 11-month-old girl presen...

Background: Acquired Von Willebrand's syndrome (aVWS) associated with hypothyroidism is rare in children and more often diagnosed during the peripubertal period in the context of Hashimoto's thyroiditis.Case presentation: A 5-year-old girl was referred to the paediatric haematology unit for rectal bleeding, anaemia, and prolonged activated partial thromboplastin time. Her developmental and learning skills were no...

Novel Role(s) for Immunoglobulin Superfamily, Member 1 (IGSF1) in the Hypothalamic–Pituitary–Thyroid Axis

Bernard Daniel

Background: Immunoglobulin superfamily, member 1 (IGSF1) was originally proposed to function as an inhibin co-receptor in pituitary gonadotroph cells. More recently, however, loss of function mutations in the human IGSF1 gene were linked to a novel syndrome of central hypothyroidism, testicular enlargement, and variable prolactin-deficiency. Igsf1-deficient mice are also centrally hypothyroid, with reduced pituitary thyrotropin-releasing hormone receptor (<em...
