Background: Pheochromocytoma is a rare adrenal tumor that can present with a variety of different symptoms. The cardinal symptoms are paroxysmal palpitations, headaches and sweating together with paroxysmal or persistent hypertension. Increasing use of CT scan contribute to the discovery of more adrenal incidentalomas and therefore more pheochromocytomas due to the workup of the incidentalomas. We intended to investigate if the presentation of the pheochromocytoma was differen...

Introduction: Phaeochromocytomas often induce hyperglycaemia. Few cases are reported with hypoglycaemic fits. The mechanism is unknown. Our findings may indicate a mechanism.The patient: A 37 year old female had a phaeochromocytoma, with typical characteristics: attacks of headache, nausea and sweating. High blood pressures, up to 237/134. Electrocardiogram indicated ischemia, normal coronary arteries on dynamic CT, normal Echo-Doppler heart examination....

Background: We have previously shown that LC-MS/MS analyses of steroid hormones are superior to immunoassays monitoring 21OHD, due to better specificity and the possibility to multiplexing several steroid hormones in the same assay. This may lead to better understanding of the individual steroid hormone profile in patients with CAH. Here we present four patients cases with the same genotype in the CYP21A2 gene, and evaluate their steroid profile by LC-MS/MS analyses.<...

Objective: Immunoassays of steroids are still used in the diagnosis and biochemical monitoring of patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21 OHD). However, high levels of steroid intermediates can promote cross-reactivity between steroids giving rise to falsely elevated levels.Design: Fifty-nine patients with classic 21OHD (38 women) were studied. Blood samples were collected in the morning after overnight medicatio...

Background: Acromegaly is associated with increased morbidity and mortality if left untreated. The therapeutic options include surgery, medical treatment, and radiotherapy. Guidelines regarding treatment algorithms and follow-up vary considerably.Aim: To evaluate consensus on the treatment and follow-up of acromegaly in the Scandinavian countries.Methods: To map the landscape of acromegaly management in the Scandinavian countries, ...

Background: Previous research show that autoimmune adrenal insufficiency develops gradually over time and inexorably results in a total inability to produce adrenal steroids. However, growing evidence suggest that a few patients preserve some steroid producing capacity.Aim: To explore the frequency of residual cortisol production and possible clinical consequences in patients with autoimmune Addison´s disease (AAD).Material an...

BackgroundResidual adrenocortical function (RAF) is present in one third of patients with autoimmune Addison’s disease (AAD), yet its clinical significance remains unknown.ObjectiveTo investigate if biomarker profiles of cardiovascular disease and inflammation are different in patients with AAD and RAF compared to patients without RAF and healthy controls.Material and methods<p...
