Opposing Effects of Childhood Obesity on Radial and Tibial Bone Microstructure

Dimitri Paul , Jacques Richard , Paggiosi Margaret , King David , Walsh Jennifer , Bishop Nick , Eastell Richard

Background: Bone mass is low in obese children when measured by conventional techniques. However, these imaging modalities cannot quantify alterations in bone microstructure and strength. High resolution peripheral quantitative computed tomography (HRpQCT – isotropic voxel size 82 mm) provides the resolution required to determine 3-dimensional in-vivo bone microstructure; microfinite element (microFE) analysis of HRpQCT images provides insight into skeletal biome...

Infancy Lipidomic Analyses and Associations with Early Nutrition and Growth

Prentice Philippa , Koulman Albert , Matthews Lee , Acerini Carlo , Ong Ken , Dunger David

Background: Links between early life exposures and long-term health outcomes may in part be due to nutritional programming, and suggested benefits of breast feeding during infancy include reduced risk of obesity and metabolic disease. Mechanisms remain unexplained but potential differences in lipid exposures during infancy may be involved.Objective and hypotheses: To explore the effects of breast- or formula-feeding on lipidomic profiles we used recently...

Prenatal Exposure to Phthalates and Phenols in Relation to Anogenital Distance at Birth in Male Infants

Fisher Benjamin G , Thankamony Ajay , Ong Ken K , Dunger David B , Hughes Ieuan A , Acerini Carlo L

Introduction: Increasing incidence of male reproductive disorders may be due to fetal exposure to putative endocrine disruptor chemicals (EDCs), such as phthalates and phenols. Anogenital Distance (AGD) is a biomarker of fetal androgen action in animals, and has recently been linked to testicular dysgenesis syndrome in humans.Objective: To examine the relationship between prenatal phthalate and phenol exposure and birth AGD in male infants.<p class="...

The Effects of Delaying Puberty with GnRH Agonists in Patients with Idiopathic GH Deficiency

Dunger David B , Lindberg Anders , Dorr Helmut G , Camacho-Hubner Cecilia , Geffner Mitchell E

Background: Treating central precocious puberty with GnRH agonist (GnRHa) to increase height gain is well-established. Although not recommended, GnRHa have also been used in patients with IGHD at onset of puberty yet there are few data on its efficacy.Objective and hypotheses: Growth prediction models derived from KIGS (Pfizer International Growth Database) may provide an opportunity to estimate additional height gain produced by pubertal blockade.<p...

Skeletal Disproportion and Final Adult Height in Childhood-Onset Crohn’s Disease

Mason Avril , Iljuhhina Jelena , Laird Susan , Ross David , Ahmed Syed Faisal , Gaya Dan R , Gerasamidis Konstantinos

Background: Short stature is a recognized complication of Crohn’s disease (CD) in children. Less is known on the impact of disease on final adult height and body proportions.Objective and hypotheses: To assess height and body proportions in 48 adults (F: 30; M: 18) with childhood (ACO) or adult (AAO) onset CD and 44 children (C) (F:22; M:22) with CD.Method: Standing, sitting height (SH) and leg length (SILL) were measured and ...

Neuroendocrine Dysfunctions Following Traumatic Brain Injury in Children: a 12-Month Prospective Study

Rojo Pilar , Carcavilla Atilano , Ortiz Irene , Arjona David , Borrego Raul , Aragones Angel

Background: Traumatic brain injury (TBI) is a frequent cause of endocrine dysfunctions. However, studies in children are scarce.Objective and hypotheses: To determine pituitary function in children after TBI. To analyze risk factors related with endocrine dysfunctions after 12 months follow up.Method: A prospective study of endocrine function in children after head injury was performed. Data was collected for baseline Glasgow coma ...

Anogenital Distance, Penis Growth, and Masculine Behaviour Evidence for Independent Neurobehavioral Effects of Foetal Versus Postnatal Androgen Exposure in Boys

Pasterski Vickie , Acerini Carlo , Dunger David , Ong Ken , Hughes Ieuan , Thankamony Ajay , Hines Melissa

Background: Associations between foetal androgen deficiency and variations in anogenital distance (AGD) suggest that AGD is a reliable indicator of foetal androgen exposure. Similarly, variation in postnatal penis growth associated with variations in testosterone show penis growth to be a potential biomarker of early postnatal androgen exposure. Though variation in early androgen exposure is also hypothesized to underlie neurobehavioral masculinisation, until now, no reports h...

The Utility of AMH for Predicting Testosterone Response to hCG Stimulation in Children with Suspected DSD

Kyriakou Andreas , McNeilly Jane D , Shaikh Guftar M , Mason Avril , Shapiro David , Ahmed Syed Faisal

Background: In children undergoing investigation of testicular function the relationship between serum anti-Mullerian hormone (AMH) and the testosterone response to hCG stimulation test (HST) is unclear.Method: 75 children (3F, 72M) with a median age of 1.08 years (range, 0.003, 14.3) were investigated for suspected DSD by AMH on D1 and testosterone on D1 and D4, before and after 3-day HST. Of these children, 27 had an additional prolonged HST. Normal te...

Management of Middle Ear and Hearing Problems in Turner Syndrome – How Can We Do Better?

Lim David , Donaldson Malcolm , Gault Emma Jane , Clement Andrew , Kubba Haytham , Mason Avril

Background: Otological problems in Turner syndrome (TS) are notoriously common and troublesome, often requiring intervention with adeno-tonsillectomy, insertion of ventilation tubes and occasionally resulting in serious disease such as cholesteatoma.Survey of otological problems in the West of Scotland: A case note review of 174 girls attending the Turner clinic in Glasgow, Scotland from 1989–2015 found that of 155 patients in whom data were availab...

A Contextual Feature-Based Recognition Approach to Quantify Trabecular Microstructure Using 1.5T Axial-MRI: An Innovative Methodology

Dimitri Paul , Lekadir Karim , Hoogendoorn Corne , Armitage Paul , Whitby Elspeth , King David , Eastell Richard , Frangi Alejandro

Background: In-vivo skeletal MRI imaging remains challenging due to the extremely short MR relaxation times (<1 ms) of protons bound to water in bone. However, each MRI sequence contains properties identifiable through feature-based recognition, highlighting characteristics relating to skeletal configuration. We thus present a novel statistical method for clinical 1.5 Tesla (T) MRI in quantifying trabecular microstructure and use HRpQCT to determine its accuracy.<...
