We present a patient who was operated on suspected Cushing syndrome based on abnormal results in overnight dexamethasone suppression tests.Case presentationA 49-year-old female patient was referred to our clinic for reoperation due to per...

Introduction: Neuroendocrine tumors (NETs) are rare tumors harboring overexpression of somatostatin receptors (SSTRs) on their cell membrane. Gallium 68-tetraazacyclododecane tetraacetic acid-octreotate (68Ga-DOTATATE) positron emission tomography/computed tomography (PET/CT) is an important imaging modality in diagnosis and staging of NETs. Because some organs such as spleen, adrenal glands and liver physiologically express SSTR, it might be challenging to distinguish some pa...

Background: LC-MS/MS is recommended for accurately measuring circulating steroids. However, laboratories using LC-MS/MS adopt various pre-analytical and analytical strategies, and little is known about comparability of results. Whether different blood derivatives impact LC-MS/MS measurements is unclear, and the benefit of unifying the calibration system among laboratories was not tested.Aim: Comparisons of LC-MS/MS measurements of circulating aldosterone...
