A 65-year-old female, with a 4 month history of left upper quadrant discomfort, was identified as having a multi-loculated para-renal ‘cyst’ on ultrasound scanning. CT identified a 13×11×10 cm heterogeneous mass arising from the left adrenal. An enlarged ill-defined left retro-crural ‘lymph node’ was also noted. There was no history of weight loss. Past medical history was unremarkable. She was no medication. Examination was unremarkable apart fro...

PYY is secreted postprandially from the endocrine L-cells of the gastrointestinal tract. PYY3–36, the major circulating form of PYY, reduces food intake in humans and rodents via high affinity binding to the auto-inhibitory NPY receptor, Y2R, within the hypothalamic arcuate nucleus.Aims: To investigate (1) the effects of length of fast on the anorexigenic actions of PYY3–36; (2) the effects of early light phase administrat...

Peptide YY(3-36) (PYY(3-36)) is secreted from endocrine L-cells of the gastrointestinal tract and is thought to induce post-prandial satiety by inhibiting the release of neuropeptide Y (NPY) in the arcuate nucleus of the hypothalamus via the hypothalamic neuropeptide Y2 receptor (Y2R). NPY mRNA expression in the hypothalamus is markedly increased with fasting. Therefore, we investigated the effect of intraperitoneal (i.p.) injections of PYY(3-36) (120ug/kg) on food intake vers...

Introduction: Obesity is a chronic and complex disease which is considered as one of the major health challenges with short- and long-term health consequences. Childhood obesity is defined as having a body mass index (BMI) at or above the 95th percentile for age and gender after two years of age. The glucagon-like peptide-1 (GLP-1) receptor agonist, liraglutide, is proven to promote weight reduction when used at a higher dose of 3.0 mg once daily. This study a...

Background: Immune checkpoint (CTLA-4, PD-1) inhibitors are increasingly used to treat cancers including advanced melanoma. Although endocrine immune related adverse events (IRAEs) are now well reported, the frequency and type of thyroid and pituitary dysfunction reported varies considerably, with hypophysitis after CTLA-4 inhibitors reported in 2–16%, and thyroid dysfunction after PD-1 inhibitors in 2–39%. In addition, recove...

Introduction: Evaluating hunger and hyperphagia is an important component of assessing children and young people with obesity. Identifying increased hunger levels will help clinicians and health professionals to taper management aspects including relevant genetic testing and providing tailored dietary and pharmacological management.Aim: The aim of this study was to evaluate the baseline hunger levels in a group of UK adolescents with severe obesity.<...

Introduction: Visceral body fat has been shown to correlate with complications related to obesity. Body mass index (BMI) is widely used to define obesity in the adolescent population; however, it does not take the overall body composition into account. We present body composition data in a group of UK adolescents attending the tertiary MDT weight management service.Methods: Data was collected on 31 patients (M:F = 15:16) attending the MDT service over a ...

Introduction: Childhood obesity is associated with several complications related to physical and mental health. Determining health-related quality of life (HRQOL) is an important outcome measure to ensure patients receive the appropriate care.Aim: We report the baseline HRQOL in a group of UK children and adolescents with severe obesity who were managed in a Tier 3 weight management service.Methods: Paediatric quality of life (Peds...

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is regarded as a precursor to the development of carcinoid tumorlets. It is confined to the neuroendocrine cell of the airway mucosa without penetration through the basement membrane and appears in a diffuse pattern, typically in association with obliterative bronchiolar fibrosis. DIPNECH belongs to the preinvasive lesions defined by the 1999 World Health Organization classification, along with atypical ade...
