Background: Primary aldosteronism is an increasingly recognised cause of hypertension, caused by excess aldosterone secretion. Screening and confirmatory tests such as saline suppression tests (SST) require accurate measurements of aldosterone and use of appropriate cut-offs. Many laboratories have chosen liquid chromatography tandem mass spectrometry (LC-MSMS) methods as issues of poor specificity have been reported for immunoassay methods. During the validat...

Introduction: Testicular adrenal rest tumours (TARTs) are a complication of congenital adrenal hyperplasia (CAH), stimulated by hyper-secretion of adrenocorticotropic hormone (ACTH). They are the main reason for fertility problems in men with CAH owing to compression of the seminiferous tubules, obstructive azoospermia and potentially permanent testicular damage. These lesions are benign and, in most patients present bilaterally. TARTs are treatable, but they can be misdiagnos...
