Introduction: Previous UK study (2009) showed that parents rather than school staff were responsible for supporting the majority of children with insulin administration (IA) whilst at school. Since then, the law has changed and the Children and Families Act 2014 (UK) places a legal duty on schools to provide the right care and support.Objective: To establish what support & facilities are available to Children & Young people (CYP) with TID whilst ...

Androgen excess in women is most commonly caused by polycystic ovary syndrome (PCOS), but sinister ovarian and adrenal pathology requiring immediate action needs to be excluded. Here we examined whether the severity of androgen excess indicates the likely underlying pathology in women evaluated for androgen excess.We included all women undergoing assessment of serum DHEAS, androstenedione (D4) and testosterone (T) by liquid chromatogra...

Background: Congenital adrenal hyperplasia (CAH) is the underlying diagnosis in most newborns presenting with 46,XX disorders of sex development (DSD). Cytochrome P450 oxidoreductase deficiency (PORD) is a rare form of CAH caused by inactivating mutations in the POR gene. The hallmark feature of PORD is combined sex-steroid and glucocorticoid deficiency due to impairment of CYP17A1 and CYP21A2. Skeletal malformations resembling the Antley-Bixler Syndrome phenotype are common i...

Introduction: Language barriers can pose a significant barrier to successful education of children and young people (CYP) with type 1 diabetes (T1DM) and their families, potentially influencing their glycaemic control.Methods: Retrospective analysis from diagnosis to 18 months post diagnosis of glycaemic control in 41 CYP with T1DM requiring interpreter support (INT) under care of our diabetes centre based within a multi-ethnic community. Median HbA1c at...

In humans, androgen synthesis crucially depends on the enzyme CYP17A1 expressed in adrenals and gonads. The 17,20 lyase activity of CYP17A1 catalyses the key step in human androgen biosynthesis, the conversion of 17-hydroxypregnenolone to the universal sex steroid precursor dehydroepiandrosterone (DHEA). For its catalytic activity, CYP17A1 requires electron transfer from P450 oxidoreductase (POR). Mutations in CYP17A1 and POR are known to disrupt human androgen s...

A key component of androgen synthesis is the availability of the pro-hormone DHEA, which is either converted to active androgens or inactivated to its sulfate ester DHEAS by DHEA sulfotransferase (SULT2A1). The latter reaction requires provision of the universal sulfate donor 3′-phosphoadenosine-5′-phosphosulfate, PAPS. In humans, PAPS is generated by the PAPS synthase isoforms PAPSS1 and PAPSS2. Recently, inactivating PAPSS2 mutations have been identified i...

Context: Turner syndrome (TS) is associated with short stature, delayed puberty, primary ovarian insufficiency, infertility, and other features. The majority of girls with TS require pubertal induction and life-long oestrogen replacement therapy. There is paucity of data in adult TS on the efficacy of pubertal induction, such as breast satisfaction. Patient-related outcome measures (PROMs) assess the quality of care and treatment from the patient’s perspective. We have em...

Introduction: NICE recommends specific annual health checks for children and young people (CYP) with diabetes aged 12 years and over to check for health of feet, kidneys, thyroid and eyes in addition to BP, BMI and HbA1c. Historically, we included annual review care processes into regular diabetes multi-disciplinary clinics. In 2017, our service was identified as negative outlier in the National Paediatric Diabetes Audit for completion of health care processes. In particular, ...

Background: Turner’s syndrome (TS) affects 25-50 per 100,000 females. Germinal cell tumour risk is described for TS with Y-chromosome presence (12%) and gonadal dysgenesis (15-35%) but other cancer risk is less well described. Neuroblastoma accounts for 6% of UK childhood cancer registrations, is the commonest cancer diagnosed in the first year of life and the most common extra-cranial solid tumour in childhood. It carries a UK incidence of 10.9 cases/million children. Pr...
