BASIC: Bone Age Study in Children

Cockill Toby , Hewitt Amanda , Wright Neil , Elder Charlotte

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,...

Collection of salivary steroids in children under conditions replicating home sampling

Tonge Joseph , Keevil Brian , Craig Jessica , Langley Joe , Whitaker Martin , Ross Richard , Elder Charlotte

Background: Measurement of salivary glucocorticoids is an accepted method for testing adrenal function and is gaining popularity as it offers a non-invasive collection technique, enabling sampling in the community or home environment, allowing tailored capture of steroid circadian rhythm and improved patient experience. However, there is little data on stability during home collection and sampling methods in young children. Current salivary collection techniqu...

Evolution of the Short Synacthen Test over a decade - a single UK centre’s experience

Ross Callum , Craig Jessica , Hariprasad Anu-Sree , Auckland Isobel , Colyer Sharon , Elder Charlotte

Background: The Short Synacthen Test (SST) is the most popular test of adrenal insufficiency (AI) worldwide. The current SST protocol at Sheffield Children’s Hospital (SCH), UK, recommends measurement of serum cortisol at baseline, then 30- and 60-minutes post stimulation, with a peak cortisol of >429nmol/l constituting a pass. Our practice has evolved to consider near-pass results as “borderline” and patients may be treated with stress do...

Effect of maternal steroid medication prescribed during pregnancy on neonatal adrenal function

Ahmed Aneeq , Hattangadi Ibani , Gopalakrishna Nagapratheek , De Silva Shamani , Elder Charlotte , Ferguson Elspeth

Background: There is limited data supporting concerns that systemic corticosteroids, prescribed in pregnancy for maternal health reasons, can suppress the neonatal Hypothalamic-Pituitary-Adrenal (HPA) axis. Our study aimed to determine if neonates born to mothers on long-term or high dose steroids are at risk of adrenal suppression.Methodology: Neonates who underwent assessment of adrenal function over a seven-year perio...

The Relationship of Baseline, Incremental and Peak Cortisol Following a Short Synacthen Test – Single-centre Analysis of Three Years’ Data

Aji Apoorva , Colyer Sharon , Burn Sarah , Dimitri Paul , Wright Neil , Krone Nils , Elder Charlotte

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...

Borderline Peak Plasma Cortisol Following Synacthen Stimulation – Single-centre Analysis of Three Years Data

Burn Sarah , Colyer Sharon , Dimitri Paul , Wright Neil , Krone Nils , Elder Charlotte

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 ...

Current Dilution Methods Cause Large Variations and Inaccuracies when Making up 1 μg Synacthen Dose

Cross Alexandra S , Sachdev Pooja , Wright Neil P , Jabbar Imran , Elder Charlotte J

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 ...

The Intra- and Inter-User Reliability of Testicular Volume Estimation – A Simulation Study

De Silva Shamani , Akbarian-Tefaghi Ladan , Langley Joseph , Stanton Andrew , Wright Neil P , Elder Charlotte J

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 ...

A Novel Non-Invasive Short Synacthen Test

Elder Charlotte , Johnson Trevor , Loxley Martin , Keevil Brian , Wales Jerry , Wright Neil

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...

A Novel Non-invasive Short Synacthen Test Validated in a Healthy Paediatric Population

Elder Charlotte , Vilela Ruben , Johnson Trevor , Kemp E Helen , Keevil Brian , Newell-Price John , Ross Richard , Wright Neil

Introduction: Worldwide the Short Synacthen Test (SST) is the most popular diagnostic investigation for adrenal insufficiency (AI) amongst both paediatric and adult endocrinologists. Cannulation and blood sampling are required making it invasive, time-consuming and resource-intensive. We have previously validated a reliably absorbed and well tolerated formulation of nasal synacthen (Nasacthin003) in healthy adult males, measuring the glucocorticoid response in salivary cortiso...
