Background: Childhood obesity remains a significant public health concern, with weight management programmes to date only showing limited success. This project aims to evaluate initial first year outcomes for our Complications of Excess Weight (CEW) Service based at our tertiary paediatric centre. Children and young people with significant obesity in our region and referred to the service, receive tier 3 weight management support, including intensive lifestyle...

Background: Ovotesticular disorders of sexual development (DSD) are a rare form of DSD with co-existence of both ovarian and testicular tissue in one or both gonads.Case report: A term infant (weight +1.38 SDS) presented at birth with severe penoscrotal hypospadias, a small phallus and a right hemiscrotum with descended gonad (external masculinization score 1.5). Pelvic ultrasound revealed no Mullerian structures, a small right gonad with probable epidid...

Background: Bone age studies require X-ray of the left hand and wrist to assess skeletal maturity. The Tanner-Whitehouse 3 (TW3) scoring method provides an objective framework for calculating bone age and specifies exact placement of the hand. In our service we have noted a number of poor quality films, caused by difficulty with hand placement, e.g. scrunching of the fingers. This compromises the ability to score accurately and in a proportion necessitates re-X-ray, with time,...

Introduction: The Short Synacthen Test (SST) is the most popular diagnostic investigation of adrenal insufficiency (AI) amongst adult and paediatric endocrinologists. AI can present insidiously and symptoms may be non-specific. The number of medical indications for glucocorticoids is growing and SST usage is correspondingly increasing. There is evidence that an early morning plasma cortisol (EMC) of below ~100–150 nmol/l is highly predictive of failing the SST and the cor...

Introduction: The Short Synacthen Test (SST) is the most popular diagnostic investigation of adrenal insufficiency (AI) worldwide. Symptoms of AI are frequently non-specific, often delaying diagnosis, however fortunately cases of adrenal crisis remain relatively rare. Diagnostic cut-offs for plasma cortisol on SST are controversial, made more complicated by modern assays and paediatric normative values extrapolated from adult data. Some advocate a division between biochemical ...

Background: The effect of profound weight loss following obesity surgery on skeletal microarchitecture and strength in adolescents has not been studied. Obese children are at an increased risk of fracture and childhood obesity leads to reconfiguration of trabecular bone without augmenting bone strength.Objective and hypotheses: To examine the impact of weight loss following 6 months treatment with an intragastric balloon supported by a lifestyle interven...

Background: The low-dose short Synacthen test is a popular diagnostic test of adrenal insufficiency in children. It is employed by 82% of UK paediatric endocrinologists. Although various dosing strategies exist, 1 μg is most commonly employed, however none of the low-dose forms are commercially available. A BSPED survey revealed 14 different methods for diluting 250 μg/ml ampoules.Objective and hypotheses: Do various dilution strategies result ...

Background: Measuring testicular volume (TV) by orchidometer is a standard method of pubertal staging in boys. A paucity of evidence exists as to its inter and intra-user reliability and the impact of clinicians’ gender, training and experience on the accuracy of measurements.Objective and hypotheses: We engineered prosthetic models of different size testes to investigate the reliability of TV estimation.Method: The study was ...

Background: A reduction in bone mass in adults and adolescents has been observed following Roux-en-Y bypass surgery with an increase in fracture risk reported in adults. However, the intragastric balloon (IGB) is a less invasive bariatric procedure.Objective and hypotheses: Given obese adolescents are at greater risk of fracture we studied the impact of a 6 month IGB insertion on skeletal mass, geometry and strength over 2 years.Me...

Background: The short synacthen test (SST) is a popular diagnostic investigation for adrenal insufficiency (AI). Cannulation and blood sampling are required making it invasive, time-consuming and resource-intensive. Salivary cortisol is a well-established alternative to serum sampling.Objective and Hypotheses: To develop a non-invasive alternative to the 1 μg SST, using a novel formulation of Synacthen (with a nasal drug enhancer, chitosan) given na...
