Postural orthostatic tachycardia syndrome (PoTS) occurs as a consequence of the abnormal functioning of the autonomic nervous system (dysautonomia). Despite the many associated conditions, the assessment and relationship to reactive hypoglycaemia has not been explored in the clinical literature.The purpose of this retrospective observational-cohort study was to identify relationships between the physical and biochemical characteristics in potential carbo...

A 50-year-old woman was referred with a history of chronic, symptomatic hypokalaemia. She also had hypertension. There was no history of diarrhoea, increased bowel motions, vomiting, or laxatives/diuretic use. She was not diabetic and she did not have menopausal symptoms.

While phaeochromocytomas are rare tumours, their identification is essential to avoid morbidity and mortality; their biochemical identification is crucial. Plasma and 24 urinary metanephrines are used as first line investigations, with plasma metanephrines increasingly used first due to its simplicity and high sensitivity/specificity. False positive results, however, can be as high as 20%, particularly secondary to medications; their exclusion is essential to avoid unnecessary...
