Background: Diagnostic work-up for Cushing Syndrome (CS) can be challenging and is based on clinical and biochemical assessments. Biochemical evidence of endogenous steroid excess is demonstrated through overnight dexamethasone suppression test (ODST), low dose dexamethasone suppression test and/or 24-hour urinary free cortisol estimation (UFC). Once endogenous steroid excess is confirmed, random serum ACTH measurement is key in determining the suspected source of steroid exce...

Background: The COVID-19 pandemic has resulted in widespread disruption to delivery of emergency and elective care in the last 2 years. Nevertheless, healthcare systems have quickly readapted to accelerate use of novel pathways for delivering clinical services. We reviewed the impact of COVID-19 pandemic on our time from community referral to definitive surgery in patients with Primary Hyperparathyroidism (PHPT).Methods: We retrospectively reviewed the w...

Background: Diagnostic work-up for Cushing Syndrome (CS) can be challenging and is based on clinical and biochemical assessments. Once steroid excess is biochemically confirmed, the diagnostic serum ACTH threshold for determining ACTH-independent Cushing is debatable. A threshold of less than 15 ng/l has been adopted in our regional guidelines.Aims: To investigate serum ACTH levels in patients with proven adrenal Cushing and to assess the clinical utilit...
