Introduction: Cushing’s disease (CD) is very rare in children and is invariably caused by a corticotroph adenoma. However, corticotroph cell hyperplasia has only been convincingly shown in two previous cases of paediatric Cushing’s disease. We report the case of a 7-year-old boy with Cushing’s disease caused by coticotroph cell hyperplasia.Case report: Our patient presented with a 10-month history of obesity, hirsutism and growth retardati...

The diagnosis of Cushing’s Syndrome (CS) requires demonstration of excess circulating cortisol. Measurement of late night salivary cortisol (LNSF) has been advocated as a simple, non-invasive and reliable outpatient diagnostic tool for patients with suspected CS but the usefulness of its metabolite cortisone (LNSE) remains unclear. LNSE levels are approximately six times higher than LNSF in saliva due to the rapid action of 11β-hydroxysteroid dehydrogenase type 2 (11...

Background: A founder mutated AIP allele, R304* was previously identified in several Irish familial isolated pituitary adenoma (FIPA) pedigrees from a small region within Mid Ulster, Northern Ireland, but the allele’s general population impact remains unknown.Aims: To estimate R304* prevalence in the general population and pituitary adenoma (PA) patients and to calculate the allele’s time to most recent common ancestor (tMRCA).<p c...
