Background/Aims: Cryptorchidism or undescended testis is a prevalent congenital urogenital condition affecting male newborns with an incidence rate ranging from 1.0 to 4.6%. Mouse models have implicated INSL3 and its receptor RXFP2 (formerly known as GREAT or LGR8) in the development of the condition. RXFP2 acts as a G protein-coupled receptor that triggers the generation of cAMP by binding INSL3. But despite the established role in testicular descent, so far ...

Defects in QSOX2, a novel regulator of STAT5B nuclear import and transcriptional activity, lead to severe post-natal growth restriction

Maharaj Avinaash , Andrews Afiya , Chatterjee Sumana , Hwa Vivian , Storr Helen

Background: Growth Hormone Insensitivity (GHI) is characterised by short stature and functional IGF-I deficiency associated with normal/elevated GH levels. Marked genetic and phenotypic heterogeneity exist, and heritable defects in GH-IGF-I axis genes/associated pathways account for mild-moderate to severe GHI cases. We report twin brothers from a non-consanguineous kindred who present with short stature and bi-allelic mutations in QSOX2 encoding the nuclear m...

A single-centre evaluation of remote video consultation for children and young people with diabetes

Andrews Edward , Odeleye Esther , Kumaran Anitha , Trevelyan Nicola ,

Background: Throughout 2020 telemedicine was rapidly deployed across health services and, during the COVID-19 pandemic, replaced many face-to-face (FTF) medical consultations. Children and young people (CYP) with diabetes present a unique opportunity for this type of consultation, due to the ability to interpret and share glucose data via other platforms. This study describes both CYP and parent experience of a new telemedicine service for CYP with diabetes.</...

Cystic Fibrosis-related diabetes

Kelly Andrea ,

Emerging in childhood and becoming increasingly prevalent to affect 40-50% of adults with cystic fibrosis (CF), CF-related diabetes (CFRD) is a common co-morbidity with the potential to negatively impact nutritional status, pulmonary function, and survival. Stymying interventions to preserve beta-cell function, the mechanisms underlying the progressive insulin secretion defects responsible for CFRD are poorly delineated. This meet-the-professor session will use case-based pres...

Effects of Selective GPER-1 Agonist G1 on Bone Growth

Iravani Maryam , Karimian Elham , Chagin Andrei , Savendahl Lars

Background: Abnormal growth is a common problem in children. Some children do not respond to growth hormone therapy and alternative treatments selectively targeting the growth plate are needed. High doses of estrogens induce growth plate closure and stop further growth. However, high-dose estrogen treatment may also have severe side effects, including increased risk of cancer and reduced fertility. The expression of estrogen receptors (ER), including GPER-1, has been demonstra...

Disrupting the Norm: The Experience of Young People with DSD

Steers Denise , Andrews Georgia , Collings Sunny , Ballantyne Angela , Stubbe Maria , Wiltshire Esko

The experiences of older adults with Variations in Sex Characteristics (VSC or Differences/Disorders in Sex Development/DSD) are well documented. However there has been a gap in the literature with respect to representing the voices of younger people. This qualitative research study has been conducted in collaboration with Intersex Trust Aotearoa New Zealand. Ten young people with VSC were recruited via health professionals, intersex advocates, support groups and social media ...

Adequate Interpretation of Cortisol Levels in Children

Chueca Maria J , Villarreal Maria , Andres Carlos , Berrade Sara , Dura Teodoro , Nova Luiz-Miguel , Rodriguez Pablo

Adrenocortical tumours are a rare disease in the paediatric population, with a higher prevalence in children under 5 years. The aetiology is partially known; in some cases it is related to mutations in the tumour suppressor gene p53 (TP 53). The classical symptoms of the Cushing syndrome are not usually present in children, so we should suspect this disease in children and teenagers with obesity or with slow growth velocity.Methods: We report a case of a...

Pituitary gland volume measured by Magnetic Resonance Imaging as diagnostic predictor of persistent Childhood-onset growth hormone deficiency

Corredor-Andres Beatriz , Walton-Betancourth Sandra , Brain Caroline , Butler Gary , Hindmarsh Peter , Dattani Mehul ,

Introduction: Pituitary imaging is important for the evaluation of hypothalamo-pituitary axis defects in patients diagnosed with childhood-onset growth hormone deficiency (CO-GHD). Published evidence shows that there is a close relationship between structural changes in the pituitary gland and growth hormone deficiency.Aim: To evaluate the relationship between clinical, laboratory and magnetic resonance imaging of the pi...

Endocrinological assessment in patients with fanconi anemia

Corredor-Andres Beatriz , Martin-Rivada Alvaro , Zubicaray Josune , Barrios Vicente , Sevilla Julian , Argente Jesus ,

Introduction: Fanconi anemia (FA) is a rare genetic disease that presents with aplastic anemia. Around 60% have short stature (SST), with a mean height of -2.2 SD. However, studies assessing the etiology of SST not having reached relevant conclusions.Aim: Our aim was to evaluate the clinical features and endocrine status in relationship to SST in patients with FA.Methods and Patients: A cross-secti...

Epidemiology of Type 1 Diabetes among children under 15 years of age in Navarre (Northern Spain) between 2012-2022

J. Chueca Maria , Berrade Sara , Andres Carlos , Elcano Leire , Bello Paula , Burillo Elisabet

The incidence of TIDM varies greatly between different countries and regions. In Navarre, located in the north of Spain, at the western end of the Pyrenees, there has been a clear increase in the incidence of TIDM, from 13,5 cases per 100000 in the decade 1990-2000 to 20,1 cases per 100000 between 2006-2011. We wonder if this upward trend has continued in recent years. Our hospital is a reference center for Pediatric Endocrinology in Navarre.Obje...
