Objective: This is a prospective audit looking at cardiovascular parameters in transpeople comparing those who have self medicated verses those who have not.Methods: Patients attending a workshop for new patients were questioned about cardiovascular risk factors including diabetes hypertension and smoking status. Measurements were made of lipid profile, glucose, blood pressure, waist, height and weight measurement. Those that were self medicating (SM) we...

A 45-year-old male to female transsexual presented with poor female fat distribution. She had been treated with oestrogen for 13 years, initially as ethinyl oestradiol to a maximum dose of 150 ug/day, presently taking 100 mcg with GNRH analogue. On this regimen she had B cup breast development but underwent breast augmentation surgery and still suffered from low self-esteem. She was dissatisfied with her body image because she perceived a male body fat distribution. Her initia...

For many animals anticipation of future changes in environmental conditions is a critical adaptation for survival. Seasonal changes in reproductive activity, body weight and adiposity, metabolism and coat condition are examples of such adaptive physiology. Clearly each of these involves neuroendocrine control. The environmental cue that triggers these changes is photoperiod, which is translated into the hormonal signal, melatonin, a product of the pineal gland. A considerable ...

Most children with diabetes are insulin deficient (type 1). We have reported type 2 diabetes in children, defined by evidence of insulin resistance, but the prevalence and characteristics in UK children is unknown. We aimed to characterise and determine the prevalence of non-type 1 diabetes in the UK. The British Society for Paediatric Endocrinology and Diabetes Clinical Trials unit undertook a cross-sectional questionnaire survey of all paediatric diabetes centres during 2000...

Background: Alstrom syndrome (AS) is a very rare multisystem disorder secondary to mutations in the ALMS1 gene, associated with infantile cardiomyopathy, retinal dystrophy, early onset obesity, and diabetes. Whilst a previous international review, including 35 males, cited pubertal delay and hypogonadism to be common, no detailed characterisation of puberty exists. This retrospective longitudinal analysis aims to describe puberty in boys with AS.<p class="...

Introduction: Prader–Willi Syndrome (PWS) is a rare genetic disorder due to loss of paternally inherited genes on chromosome 15q11-13. It is characterised by neonatal hypotonia, childhood hyperphagia and obesity, hypogonadism, cognitive and behavioural disabilities, and development of scoliosis. PWS multidisciplinary (MDT) clinics were introduced from 2004 at Birmingham Children’s Hospital, a tertiary paediatric centre. This enabled centralised coordination of growth...

Introduction: Prader–Willi Syndrome (PWS) is a rare genetic disorder due to loss of paternally inherited genes on chromosome 15q11-13. It is characterised by neonatal hypotonia, childhood obesity, hypogonadism, cognitive and behavioural disabilities, and development of scoliosis. We aimed to review the impact of growth hormone (GH) doses, scoliosis and IGF1 levels on height gain in children with PWS.Methods/design: Retrospective observational study ...

Introduction: Bardet-Biedl syndrome (BBS) is a monogenic disease characterized by retinitis pigmentosa (>90%), obesity (72–86%), insulin resistant diabetes, and hypogonadism. Weight management is challenging due to frequent association of learning and visual impairment. At our BBS MDT clinic, dietetic review is provided at each visit. Dietetic input focuses primarily on reduced fat and sugar content in diet and exercise is encouraged. Individualised written dietary pl...

Background: Hypothalamic hamartomas (HH) are congenital, benign tumours consisting of disorganised neuronal cells within the hypothalamus. They usually present with precocious puberty, seizures, behavioural abnormalities, either in isolation or combined.Aims: To look at the endocrine outcomes of patients with HH.Methods: A retrospective casenote review of all patients diagnosed with HH over a 20-year period within a single endocrin...

A retrospective single centre audit was conducted on the effects of polycythaemia in trans-male and native male.Polycythaemia is a recognised side effect of testosterone treatment. It could be viewed as a maker of excess testosterone action. We examined whether lipid profiles as a marker of cardiovascular risk differed in a population of polycythaemic transmen (TM) and native males (NM).Forty-six NM and 12 TM were identified to hav...
