Neuroendocrine tumours are slow growing and could be mistaken for other more malignant tumours with poorer prognosis. Their secretory profile may alter with time. The importance of awareness of these tumours and their clinical behaviour is illustrated by the case of a 78-year-old woman who presented with recurrent fasting hypoglycaemia.The patient had been diagnosed with metastatic pancreatic adenocarcinoma a year previously on the basis of radiographic ...

IntroductionThe secretion of multiple hormones occurs in both a circadian and an ultradian manner. Both animal and human studies have shown that cortisol has an ultradian rhythm. Variations in ultradian cortisol secretion may explain inter-individual variation in the stress response.ObjectiveWe have developed an automated blood sampling system (ABS) that allows undisturbed sampling of blood, thus reducing str...

Background: Cushing’s syndrome is a well-known risk factor for endothelial dysfunction, cardiovascular morbidity and mortality.Objectives: We aimed to prospectively investigate changes in metabolic and cardiovascular parameters and their correlations with markers of endothelial function in patients with endogenous Cushing syndrome following remission. Methods: Adult patients newly diagnosed with endogenous Cushing’s Syndr...

Background: Millions of people worldwide take an intentional nap or siesta after lunch, but data describing potential health effects of naps are very limited. We report on associations between napping and metabolic syndrome risk in a large older Chinese group.Methods: Data from 16 480 older participants (≥50 years) from the Guangzhou Biobank Cohort Study were analysed. Sociodemographic parameters, including frequency of lunch-time napping were coll...
