Background: Mild isolated neonatal hyperthyrotropinaemia (HTT), defined as elevated thyroid stimulating hormone (TSH) with normal free thyroxine (FT4) concentrations, may be identified by newborn screening programmes for congenital hypothyroidism (CHT) or when neonatal thyroid function tests (TFTs) are performed for a clinical indication. Reported HTT incidence rates vary (from 0.001-0.1%)1. Case definition also varies, with some authors using a TSH...

Background: Research on the impacts of achondroplasia on children's functioning and well-being is limited. The purpose of the study was to investigate the impacts of achondroplasia on children's daily lives to support the development of an impact measure of achondroplasia on children's functioning and well-being.Methods: Individual telephone interviews and one parent focus group were conducted in the United S...

Aims: To examine growth, body composition and glucose metabolism during childhood in children born small for gestational age (SGA).Methods: Single centre cohort study of 150 children (63 boys), identified from newborn records as being born SGA (birth weight SDS <−1.5) and assessed between the age of 4 and 7 years. Data collected included: anthropometric parameters (height, weight, BMI: transformed into age- and sex-adjusted SDS), lean and fat m...

Background: Polycystic ovarian syndrome (PCOS) is the most common cause of oligomenorrhea and hyperandrogenism. Diagnostic criteria for PCOS includes ovarian dysfunction and clinical or biochemical evidence of hyperandrogenism. The differential diagnosis includes congenital adrenal hyperplasia as well as steroid producing tumors.Case presentation: 18-years-old female presented to establish care with a history of PCOS diagnosed at the age of 11 years. She...

Introduction: Bardet-Biedl syndrome (BBS) is a rare, pleiotropic, autosomal recessive disorder, with prevalence between 1 in 100,000 – 160,000 in Europe and the USA. It is characterised by 6 cardinal features: rod-cone dystrophy, truncal obesity, cognitive impairment, hypogonadism and genitourinary anomalies, postaxial polydactyly and renal dysfunction, as well as a plethora of secondary features spanning multiple body systems. BBS belongs to a family of ...

Background: Individuals with congenital adrenal hyperplasia (CAH), a form of adrenal insufficiency, are exposed to daily non-physiologic, non-circadian cortisol profiles due to both the disease and therapeutic limitations. Dysfunction in the hypothalamic-pituitary-adrenal axis is strongly associated with depressive disorders. However, little is known about the prevalence of depression among children and young adults with CAH. We investigated the prevalence of ...

Background: Turner syndrome (TS) arises from a complete or partial loss of one X chromosome (45,X) and is the most common genetic cause of primary ovarian insufficiency (POI) in women. Surprisingly little is understood about the pathogenesis of POI in TS beyond an acknowledged germ cell loss throughout the second trimester. Although X chromosome haploinsufficiency likely contributes, the variability in reproductive phenotype in 45,X TS suggests it is not the o...

Background: Giant cell granulomas (GCG) are uncommon bony lesions that most commonly affect the maxilla and mandible; whilst generally benign they can be disfiguring to the face. Historically, GCGs have been treated with steroids or bisphosphonates to try and avoid surgical resection. Over recent years denosumab, a human monoclonal antibody which acts against the receptor activator of nuclear factor kappa B ligand, has been shown to be effective in treating GC...

Introduction: Bardet-Biedl syndrome (BBS) is a rare, autosomal recessive ciliopathy, with a prevalence of 1 in 100,000 – 160,000, caused by mutations across >20 known genes encoding for proteins responsible for the integrity of the primary cilium/basal body complex. Endocrinopathies associated with BBS include hypogonadism, hypothyroidism, and the metabolic complications of obesity. The endocrine characteristics of a large adult BBS cohort have been r...

Background: The presentation of early-onset Primary Ovarian Insufficiency (EO-POI), most often with primary amenorrhea, is at one end of a spectrum spanning 40 years. The aetiology of POI is frequently unclear but next generation sequencing of varied age groups has identified several associated genetic variants. Whether girls with EO-POI are more likely to have a genetic aetiology than those with later presentations remains unknown.<stro...
