Introduction: Gas chromatography/mass spectrometry based steroid profiling has been proposed as a tool for differentiating adrenocortical carcinoma (ACC) from benign adrenocortical adenoma (ACA). We retrospectively examined urinary steroid profiles from ten patients with ACC and 14 patients with ACA to determine, if the steroid profiles were predictive in distinguishing benign from malignant disease.Methods: Patients who had undergone adrenalectomy for r...

Introduction: The diagnosis of Cushing’s syndrome (CS) can be challenging and there is no single gold standard diagnostic test. Endocrinologists rely on a combination of plasma cortisol (before and after dexamethasone), midnight salivary cortisol and urinary free cortisol (UFC) to make the diagnosis. Assessment of urinary corticosteroids and their metabolites, measured by gas chromatography–mass spectrometry (GC–MS), provide a comprehensive picture of corticoste...

Introduction: In children undergoing investigation of testicular function the relationship between serum anti-Müllerian hormone (AMH) and the testosterone response to hCG stimulation test (HST) is unclear.Methods: 71 children (three females and 68 males) with a median age of 1.08 years (range: 0.003, 14.3) were investigated for suspected DSD by AMH on D1 and testosterone on D1 and D4, before and after 3-day HST. Of these children, 27 had an addition...

Background: Calculation of a urinary steroid metabolite ratio (uSMR) may be a useful method of improving diagnostic yield when investigating disorders of steroid hormone synthesis.Objective & HypothesisTo investigate the range of uSMR in children with suspected disorders of steroid hormone synthesis.Population / MethodsTen ratios were calculated on steroid metabolite data analysed b...
