Context: Congenital hypothyroidism from thyroid dysgenesis (CHTD) is mainly a sporadic and non-syndromic condition occurring in 1:4,000 live births. In contrast to rare cases of syndromic monogenic CHTD, non-syndromic (NS) CHTD shows low familial recurrence risk (~2%) and low concordance rate between MZ twins, suggesting a two-hit scenario combining post-zygotic events with either a de novo monogenic mutation or incomplete penetrance of polyg...

Acar Sezer , Demir Korcan , Kırbıyık Ozgur , Paketci Ahu , Murat Erdoğan Kadri , Abacı Ayhan , Bober Ece

Introduction: Various types of mutations in GHRHR cause isolated growth hormone deficiency type 1B. Here, we report the clinical features associated with deletion of whole GHRHR gene for the first time.Case: A four-year–and-nine-month-old otherwise healthy girl was admitted due to short stature. She was born at term with a birthweight of 3750 gr. Her height velocity slowed down after 2 years of age. The mother (157.8 cm, −0.8...

Somavaratan (VRS-317) Treatment of Children with Growth Hormone Deficiency (GHD): Results at 2 Years (NCT02068521)

Bright George , Moore Wayne V. , Nguyen Huong Jil , Kletter Gad B. , Miller Bradley S. , Fechner Patricia Y. , Ng David , Humphriss Eric , Cleland Jeffrey L.

Background: Somavaratan, a novel long-acting rhGH fusion protein with t1/2>100 h, previously demonstrated clinically meaningful improvements in height velocity (HV) and IGF-I in prepubertal GHD children (Moore JCEM 2016).Objective and hypotheses: To evaluate maintenance of somavaratan treatment effects in the 2nd treatment year.Method: After subcutaneous pediatric doses were evaluated in a single dose PK/PD study (<e...

Peripheral nerve conduction velocity in children and young adults with type 1 diabetes mellitus as a marker of metabolic control

Oberhauser Sarah , l'Allemand Dagmar , Heldt Katrin , Gozzi Tiziana , Stasinaki Aikaterini , Eilers Miriam , Lütschg Jürg , Broser Philip

Background: Nerve conduction velocity (NCV) abnormalities are considered as early signs of peripheral neuropathy in patients with diabetes mellitus (DM). We investigated which determinants NCV is subject to and how it is related to markers of metabolic control.Methods: We included 51 patients treated at the outpatient clinic of paediatric diabetology because of their type 1 DM and randomly assigned them for a nerve condu...

Background: Body mass index not allow to discriminate the proportional composition of the different body compartments: fat mass and fat-free massObjective: The aim of this study is to elaborate standardized values of the fat mass index (FMI) and fat-free mass index (FFMI) in healthy adolescents (both sexes) using anthropometric techniques in order to be available as reference standards in daily clinical practice.<p c...

The Prolactin (PRL) – Growth Hormone (GH) Relationship during Growth Hormone Stimulation Tests

Laron Zvi , Silbergeld Avivah , Barazani Chen , Lilos Pearl

Background: Despite many similarities between the structure, receptors and proliferative and growth promoting actions, the interrelationship between PRL and GH in clinical conditions has received little attention.Aim: To determine the PRL response to GH stimulation tests.Subjects: Prepubertal and early pubertal boys (n=581) and girls (n=502) with short stature.</p...

Poor Weight Gain in Prader-Willi Syndrome – Not Always Over-restriction Consider Coeliac Disease

Lateva M , Kassim A , Meade C , Maher R , McCrann A , Roche E

Introduction: Prader-Willi Syndrome (PWS) is a complex genetic condition associated with feeding difficulties, hypotonia, developmental delay in infancy; hyperphagia leading to extreme obesity, growth failure and behavioral problems in childhood. Coeliac disease (CD), is an autoimmune disease characterized by gluten intolerance and a variety of symptoms most commonly diarrhea or constipation and failure to thrive. In PWS the challenge is to optimize growth while avoiding obesi...

Unusual Case of Combination of Beckwith-Wiedemann Syndrome and SHOX Gene Deficiency

Cassano Gilda , Osimani Sara , Pajno Roberta , Pitea Marco , Partenope Cristina , Russo Silvia , Pozzobon Gabriella

Background: Beckwith-Wiedemann Syndrome (BWS) is an overgrowth disorder involving a predisposition to tumor development, etiologically connected with genetic/epigenetic dysregulation. The main features of BWS include omphalocele, macroglossia and macrosomia; however there is significant clinical heterogeneity. SHOX mutation is a frequent cause of short stature with high penetrance, but extremely variable clinical expression. The mean adult height is -2.2 SDS. The presence of m...

46,XY Complete Gonadal Dysgenesis with Late Diagnosis

Mladenov Vilhelm , Andonova Silvia , Savov Alexey , Hachmeriyan Mari , Popova Ralitza , Iotova Violeta

Background: 46,XY Complete Gonadal Dysgenesis (Swyer Syndrome) is a rare cause for DSD with incidence ≈1:80000. It is characterised by defective formation of the gonads as a result of structural anomalies in the sex chromosomes or mutations in specific genes. In 20% of the patients deletion/mutation in SRY can be found. Mutations, deletions or duplications in other genes (NRD5A1, DHH, DAX1, WNT4, DMRT, etc.) are also reported. The phenotype is completely female and the d...

Astrocytes and Neuroendocrine Control

Chowen Julie A

Glial cells are the most abundant cell type in the CNS. Although they were originally thought to only play a supportive role for neurons, it is now clear that glial cells are involved in all aspects of brain function. Understanding how glia, and in particular astrocytes, tanycytes and microglia, participate in the neuroendocrine control of metabolic homeostasis has come to the forefront in recent years. This is largely due to the observation that high fat diet-induced hypothal...
