BACKGROUND: The differential diagnosis of adrenocorticotropin (ACTH)-dependent Cushing's syndrome (CS) remains a challenging issue for clinical endocrinologists. In this respect, bilateral inferior petrosal sinus sampling (BIPSS) appears to be the most sensitive and specific test. Here, we report our 15-year experience of analyzing the performance of BIPSS, both in the ...

When evaluating delayed puberty, it is essential to determine the underlying cause. This can be done with history and physical exam as well as basal gonadotropin levels, bone age, and further testing as indicated. When the cause is hypogonadism, an underlying condition should be treated if present; otherwise lifelong hormonal ...

BACKGROUND: Acromegaly, which may be present in patients with McCune-Albright syndrome (MCAS), in association with café-au-lait spots, precocious puberty, and fibrous dysplasia, is often difficult to treat surgically because skull base bone dysplasia prevents the removal of the pituitary adenoma. Somatostatin analogs (SAs) generally give only partial responses. The use ...

Adrenal insufficiency is a rare disease, but its prevalence is increasing. The most frequent cause of primary adrenal insufficiency in western countries is autoimmune adrenalitis, whereas secondary adrenal insufficiency is most often caused by pituitary tumours and their treatment (e.g., surgery). Chronic glucocorticoid replacement consists of hydrocortisone 15-25 mg/day in ...

BACKGROUND: The integrity of the hypothalamic-pituitary-adrenal (HPA) axis is a major determinant of the host response to stress. Recent studies have proven that low doses of hydrocortisone and fludrocortisone can significantly reduce mortality in patients with relative adrenal insufficiency (RAI) without increasing adverse events. STUDY DESIGN: This study was a ...
