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...

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...

Clinicopathological Characteristics of Papillary Thyroid Cancer in Children With Emphasis on the Pubertal Status and Association With BRAFV600E Mutation

Poyrazoglu Sukran , Bundak Ruveyde , Bas Firdevs , Darendeliler Feyza

Background: Papillary thyroid cancer (PTC) constitutes more than 90% of the thyroid cancer in children. PTC behaves differently in prepubertal children than in pubertal children and between children and adults. BRAF gene activating mutations lead to PTC by creating aberrant activation. The most common mutation is BRAFV600E.Objective and hypotheses: To evaluate clinicopathological characteristics of PTC patients with emphasis on the pubertal st...

Clinical Characteristics of 30 Patients with 45,X/46,XY Mosaicism

Poyrazoglu Sukran , Saka Nurcin , Bas Firdevs , Bundak Ruveyde , Darendeliler Feyza

Background: 45,X/46,XY mosaicism is associated with a broad spectrum of phenotypes, ranging from ambiguous genitalia at birth to patients with a completely male or female phenotype. Turner syndrome stigmata and associated anomalies could be found in these patients.Objective and hypotheses: To evaluate clinical presenting symptom and follow-up data of 30 patients with 45,X/46,XY karyotype.Method: Thirty patients with 45,X/46,XY mosa...

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...

Background: Crohn’s disease is a relapsing systemic inflammatory disorder with inflammatory bowel disease (IBD) due to up-regulation of pro-inflammatory cytokines including TNFα. More than 80% of newly diagnosed children present with growth failure Paediatric gastroenterology units in the UK submit data to the UK IBD database which can be accessed when required. One aim of current treatment protocols is to promote growth. Studies on the use of anti-TNFα antibodi...
