Epigenetics, imprinting and growth

Temple I Karen ,

Human imprinting disorders are congenital disorders of growth, development and metabolism, associated with disturbance of gene dosage at imprinted loci across the genome. Causes of disease include point mutations, structural variants, uniparental disomy and ‘epimutations’ with a parent of origin specific effect. Further complexity underlies the causes of the epigenomic errors that may be the result of genetic and environmental factors at different times during the de...

Relation Between CNP Signaling Pathway and the Effect of Combined Treatment with GnRHa and rhGH on the Linear Growth in Mid/Late Pubertal Girls at Great Bone Ages with CPP or EFP

M A Hua-mei , S U Zhe , L I Yin-ya

Objectives: To evaluate the effect of combined treatment with GnRH analogue (GnRHa) and recombinant human GH (rhGH) on the linear growth in mid/late pubertal girls at great bone ages with central precocious puberty (CPP) or early and fast puberty (EFP). To investigate the relation between C-type natriuretic peptide (CNP) signaling pathway and GH’s effect on linear growth in these girls. Methods 22 girls were diagnosed as CPP or EFP, whose bone ages were older than 11.5 ye...

Relation Between CNP and the Effect of Combined Treatment With GnRHa and GH on the Linear Growth in Mid/Late Pubertal Girls with Central Precocious Puberty or Early and Fast Puberty at Great Bone Ages

Hua-mei M A , Zhe S U , Yin-ya L I

Background: It’s well known that GnRH analogue (GnRHa) could not improve the final height of mid/late pubertal girls with central precocious puberty (CPP) or early and fast puberty (EFP) for their low growth potential.Objectives: To evaluate the effect of combined treatment with GnRHa and GH on the linear growth in mid/late pubertal girls with CPP/EFP at great bone ages. To investigate the relation between C-type natriuretic peptide (CNP) and GH&#14...

Prevalence of Vitamin D Deficiency in Sickle Cell Anaemic Children in Jos, Nigeria

Abok Ibrahim I , Mukuwhana Rensom , Konrad Katja , Okolo Selina

Background: Children with SCA are six times likely to be vitamin D deficient. The prevalence of VDD in SCA is 65–100% (USA, Jeddah, Spain, England). Reasons for these include: recurrent illness, hospitalization, Increase resting energy expenditure, poor appetite, inadequate food intake, increased energy & micronutrient needs and probably excessive body covering. VDD in SCA is associated with increasing co morbidities. However, there are no studies from Nigeria the cou...

The impact of the Covid-19 pandemic on the UK National Hypothalamic-pituitary Axis Tumour (HPAT) multidisciplinary meeting

Bosch i Ara Laura , Spoudeas Helen , Wei Gan Hoong ,

Background: The HPAT multi-disciplinary meeting (MDT) was set up in 2011 with the aim to improve collaboration with other hospitals treating children with rare paediatric suprasellar brain tumours. It is a monthly remote meeting conducted virtually.Objective: To evaluate the impact of COVID19 pandemic by comparing the number of meetings, cases (news/previously discussed), diagnosis, attendees, specialties, centres and ou...

Growth, Pubertal Course and Long-Term Outcome of 46,XY Boys Born with Atypical Genitalia and Low Birthweight

Tack Lloyd , Straaten Saskia van der , Cools Martine , consortium On behalf of the I-DSD

Introduction: Boys born small for gestational age (SGA) often have undermasculinized genitalia. Little is known about the pubertal development and gonadal function on a longer-term in this specific group of males.Aims: To determine the (pubertal) development and long-term urological and endocrine outcome of undermasculinized boys born SGA compared to undervirilized boys born appropriate for gestational age (AGA).<p c...

Efficacy and Safety of Denosumab Treatment in a Boy with Cherubism

Kawamura Haruka , Watanabe Satoshi , I Takashi , Asahina Izumi , Moriuchi Hiroyuki , Dateki Sumito

Introduction: Denosumab is an inhibitor of receptor activator of nuclear factor kappa-B ligand that strongly suppresses differentiation and function of osteoclasts. Cherubism is a rare autosomal dominant disorder characterized by symmetrical swelling of the mandible and the maxilla. In patients with cherubism, the bone is replaced by a fibrous granuloma containing multinucleated giant cells, which are differentiated into activated osteoclasts<p class="abst...

Measured Free 25-Hydroxyvitamin D in Healthy Children and Relationship to Total 25-Hydroxyvitamin D, Calculated Free 25-Hydroxyvitamin D and Vitamin D Binding Protein

Bosch i Ara Laura , Lopez-Molina Maria , Santillan Cecilia , Murillo Marta , Valls Aina , Bel Joan

Introduction: Vitamin D deficiency in children is still a global health problem. Measuring free 25-hydroxyvitamin D concentrations could provide a better estimate of the vitamin D status than total 25-hydroxyvitamin D (25(OH)D) levels.Objective: To assess the relationship between measured free vitamin D (m-f25(OH)D) and calculated free 25(OH)D (c-f25(OH)D), total 25(OH)D, intact parathyroid hormone (iPTH) and other markers of phosphocalcic metabolism.

A Large Consanguineous Family with a Mild and Transient form of Autosomal Recessive Pseudohypoaldosteronism type 1 (PHA1) Caused by a Novel Mutation in the SCNN1A Gene: Functional Studies

Efthymiadou Alexandra , Gautschi I , vanBemmelen MX , Sertedaki Amalia , Chrousos George , Schild Laurent , Chrysis Dionisios

Background: PHA1 is a rare inherited disease characterized by resistance to aldosterone action and distinguished in two forms: the autosomal dominant renal form caused by mutations of the NR3C2 gene (MR) and the autosomal recessive systemic form caused by mutations of the subunit genes SCNN1A, SCNN1B, SCNN1G of the epithelial sodium channel (ENaC). The classic phenotype of the autosomal recessive form of PHA1 is usually severe, lifelong, and expressed with mu...

The Shape of the Glucose Curve and Time to Glucose Peak During an Oral Glucose Tolerance Test as Indicators of Beta Cell Function in Obese Adolescents

Sabolić Lavinia La Grasta , Stipančić Gordana , Šepec Marija Požgaj

Introduction: Morphological characteristics of the glucose concentration curve during an oral glucose tolerance test (OGTT) may reflect differences in insulin secretion and sensitivity. Whether the shape of the glucose curve and time to peak glucose concentration can be used as indicators of beta cell function and markers of type 2 diabetes risk in obese adolecents is still uncertain.Aims/hypothesis: The purpose of this cross-sectional study was to asses...
