Transsphenoidal surgery effective in children with Cushing’s disease

Transsphenoidal surgery, a minimally invasive procedure to remove pituitary tumors through the nose, achieved long-term remission in nearly all children with Cushing’s disease who participated in a single-center study in China. “While recurrence occurred in a minority of patients, primarily those with [small tumors], durable disease control is attainable for…

Test for Cushing’s still performs well with limited measurements

Limiting the number of measurements in the low-dose overnight dexamethasone suppression test (oDST), which is commonly used to diagnose Cushing’s syndrome, does not affect the test’s performance, a study showed. A new protocol, called Reflex, performs additional tests only among people whose initial tests suggest the presence of Cushing’s.

Skin cream deemed cause of woman’s Cushing’s syndrome

Long-term use of topical corticosteroids for a genetic skin condition caused Cushing’s syndrome and adrenal insufficiency — low hormone production from the adrenal glands — in a 50-year-old woman, according to a case report. “This case highlights the risk of systemic complications from chronic topical corticosteroid use,” the researchers wrote.

Using noninvasive test combo can correctly distinguish Cushing’s

A combination of two noninvasive tests — the dexamethasone suppression test and high-resolution MRI scans — was found to correctly distinguish between Cushing’s disease and ectopic Cushing’s syndrome in patients, according to a new study. The accuracy seen in combining these tests was comparable to that of bilateral inferior…
