Development of Pubertal Gynaecomastia: a Longitudinal Cohort Study

Mieritz Mikkel G , Hagen Casper P , Juul Anders

Background: Pubertal gynaecomastia (PG) is considered a clinical sign of an oestrogen–androgen imbalance at the breast tissue level although little evidence exists. PG occurs in 40–60% of adolescent Caucasian boys, and in most cases however, no underlying endocrinopathy can be identified. Very few longitudinal studies on PG exist.Objective and method: As a part of the longitudinal COPENHAGEN Puberty Study we followed 110 healthy Danish boys (ag...

Tuncerler Gülten , Özyurt Gonca , Uzun Hamide , Çalan Özlem Gürsoy , Küme Tuncay , Dündar Bumin Nuri , Çatli Gönül

Introduction: Neurotensin is a 13 amino acid peptide with central and intestinal effects. It has been shown to decrease intestinal and gastric motility, increase the absorption of fat by regulating the release of pancreas and bile acid. In addition, it is reported that there is also an anorexigenic effect of the neurotensin released from the central nervous system. In the literature, conflicting results related to serum / plasma neurotensin levels were reporte...

Introduction: Thyroid cancers are rare cancers in children and their incidence is 1.4% in pediatric malignancies. However, its frequency is increasing. While the incidence of prepubertal children is equal among girls boys, it increases with age in female patients. Radiotherapy, which is applied to the neck region, and hashimoto disease are the risk factors. The relationship between Hashimoto's disease and papillary thyroid cancer is thought to be assoc...

Er Eren , Aksoylar Serap , Mehdiyeva Humay , Özek Gülcihan , Özen Samim , Göksen Damla , Darcan Sükran

Introduction: Gonadal insufficiency is a common long-term endocrinological complication of BMT and is mainly associated with the chemotherapy protocol. In the literature, gonadal insufficiency after BMT varies between 66% -80% in girls and 35-60% in boysAim: to investigate the frequency and the factors affecting gonadal insufficiency in cases with BMT due to non-malignant indications in children or adolescenc...

Rare Cause of 46,XY Sexual Development Disorder: 17β-Hydroxysteroid Dehydrogenase Type 3 Deficiency

Manyas Hayrullah , Eroğlu Filibeli Berna , Ayranci İlkay , Saka Güvenç Merve , Nuri Dündar Bumin , Çatli Gönül

Introduction: 17β-hydroxysteroid dehydrogenase type 3 (17βHSD3) enzyme deficiency is a rare cause of 46 XY disorder of sexual development. It is inherited autosomal recessively and clinical phenotype is highly heterogeneous and depends on the mutation severity. Conversion of androstenedione to testosterone deteriorates due to lack of enzyme.Objective: In this case report, we present a case who was born en...

Two Different Endocrine Cancer, One Disease; DICER-1 Mutation

Tatli Zeynep Uzan , Direk Gül , Özcan Alper , Hatipoglu Nihal , Kendirci Mustafa , Kurtoglu Selim

Autosomal dominant DICER1 mutations are among the causes of early-onset familial cancer. DICER1 mutation has been shown in pleuropulmonary blastomas as well as ovarian tumors, thyroid, parathyroid, pituitary, adrenocortical and testicular tumors. It is important to be aware of the risk for the development of other cancers in the follow-up of these cases.Cases: Case-1: Previously known to be healthy 8,5-year-old girl presented with compla...

Intestinal Ganglioneuromatosis as First Manifestation of Multiple Endocrine Neoplasia 2B in a Premature Girl

Leunbach Tina Lund , Madsen Mette , Nielsen Rasmus G , Hansen Dorthe , Mathiesen Jes S

Introduction: Multiple endocrine neoplasia 2B (MEN2B) is a rare cancer syndrome primarily caused by the M918T (95%) and A883F (<5%) germline mutations in the REarranged during Transfection (RET) proto-oncogene. Aggressive and early onset thyroid medullary carcinoma is the hallmark of the disease. Cure rates in M918T carriers who had thyroidectomy before and after 1 year of age were 83% and 15% respectively. More t...

Extreme Hypercalcaemia: Watch for Glycogen Storage Disease Type 1a with Hyperinsulinism

christesen henrik , Nielsen Rasmus G , Lund Allan M , Cananguez Arlen A , Schou Anders J

Background: Hypercalcaemia in infants may reach extreme levels due to hyperparathyroidism, subcutaneous fat necrosis, or vitamin D intoxication. Normal values for p-parathyroid hormone and p-calcitriol prompt search for other causes.Methods: Hospital file evaluation, case report.Results: A 5½-months-old Caucasian girl of non-consanguineous healthy parents was referred due to w...

The Diagnostic Yield of a Targeted Next Generation Sequencing Panel in Children with Short Stature of Undefined Aetiology

Perchard Reena , Murray Philip G , Highton Georgina L , Whatmore Andrew J , Clayton Peter E

Background: Currently, data on the diagnostic yield of targeted gene panels using next generation sequencing (NGS) in children with short stature of undefined aetiology (SSUA) are limited. EPIGROW (ClinicalTrials.gov ID NCT00710307) was a prospective European epidemio-genetic study in which a targeted NGS panel including 69 genes associated with short stature (e.g. primordial growth disorders and skeletal dysplasias) was performed in 263 patients and 263 controls. In these pat...

Central Venous Cathether-Associated Thrombosis in Children with Congenital Hyperinsulinism

Yau Daphne , Salomon-Estebanez Maria , Chinoy Amish , Murray Philip G , Banerjee Indi

Introduction: Congenital hyperinsulinism (CHI) is the most common cause of hypoglycaemia in infancy caused by dysregulated insulin secretion. The management of severe hypoglycaemia often requires the administration of high dextrose-containing fluids through a central venous catheter (CVC). However, CVCs carry the risk of complications including thrombosis. We sought to determine the incidence of CVC-associated thrombosis in patients with CHI and examine associated risk factors...
