Context: Prior studies of children with endogenous Cushing syndrome (CS) have identified cognitive decline despite reversal of brain atrophy after remission as well as residual impairment of quality of life measures. Although parental observations support personality changes with CS, significant psychopathology has not been described. We investigated the feasibility of using paediatric Patient-reported outcomes (PROMIS) using a computer interface to assess patient perception o...

Context: Hair cortisol has been recently studied to determine evidence of hypercortisolemia in humans. This test may be valuable in estimating cortisol levels, particularly in patients with cyclical Cushing’s syndrome (CS).Objective: To determine correlations with biochemical evidence of CS, and to compare hair cortisol measurements in patients with CS to normative data.Methods: Hair samples from 49 study subjects were collect...

Background: General anaesthesia and surgical intervention in humans are known to affect the function of the hypothalamic–pituitary–adrenal axis (HPA). In the literature there are conflicting reports about the effect of propofol, a commonly used intravenous anaesthetic agent, on HPA function.Case reports: We report two males (11 and 12 years) with ACTH-dependent Cushing syndrome (CS) who underwent inferior petrosal sinus sampling (IPSS) with gen...

Background: Various genetic syndromes have identified distinct and consistent behavior patterns. Carney complex (CNC) is a rare multiple endocrine neoplasia syndrome first described by Dr Carney in 1985 as a complex of myxomas (cardiac, skin), spotty skin pigmentation, and endocrine over activity. CNC is caused by mutations of the PRKARIA gene that encodes the RIα regulatory subunit of Protein kinase A (PKA). We recently reported that a Prkar1a heterozyg...

Context: Primary aldosteronism (PA) is a common cause of secondary hypertension, and some PA adrenal tumors co-secrete glucocorticoids, causing subclinical or overt Cushing syndrome (CS). We recently reported correlations between hair cortisol concentration (HCC) and serum and urinary levels of cortisol in patients with CS.Objective: To determine correlations of segmental hair cortisol and biochemical markers of a referred cohort of patients for the eval...
