Carney’s triad; a diagnosis based on the presence of three associated neoplasms; epithelioid leiomyosarcoma, pulmonary chondroma, and extra-adrenal paraganglioma remains a rare diagnosis. Here we report a 52-year-old female investigated for chronic cough. Initial chest X-ray demonstrated calcified masses, and CT thorax confirmed a left pulmonary lesion measuring 41 mm in diameter with 3 adjacent smaller nodules up to 20 mm. A chondroid pattern o...

Introduction: The importance of good transition care has been highlighted by NICE and NHSI. Over the last 5 year we have focused on transforming our endocrine transition service.Background: Our centre took part in the BSPED/BES-led 2014 National Adolescent Care and Transition Audit of Young people with Hormone Conditions. From this we identified key areas for service improvement including: families wanted to establish a better relationship with and have ...

Craniopharyngioma is a rare benign pituitary tumour that occurs in children and adults. Recurrence rates are high (up to 90%) but factors underpinning this are unclear, particularly in cases of childhood onset. We aimed to investigate factors that may influence subsequent recurrence rates in childhood onset craniopharyngiomas in patients attending our centre. A retrospective study of patients followed up at the Oxford Late Effects of Childhood Cancer service was conducted. Pat...

Background: Hypopituitarism is a potential complication of trans-sphenoidal adenomectomy (TSA). Recovery of pituitary function can occur, and reassessment is required to avoid unnecessary hormonal replacement. However, frequency of re-testing is variable across centres. Aim of this study was to determine recovery rates and time to recovery of hypothalamo-pituitary adrenal (HPA) and thyroid axis after TSA.Methods: We performed a single-centre, retrospecti...

We present a case of 71-year-old gentleman who presented with bitemporal hemianopia in 2008 with pituitary apoplexy compressing the optic chiasm. Prolactin was 55287MU/l, with deficiency of all other anterior pituitary hormones. He underwent transphenoidal adenectomy (TSA). Prolactin was 35633MU/l post-operatively and cabergoline was commenced. Histology was consistent with a lactotroph adenoma with MiB-1 index of 3–5%. Visual fields recovered and prolactin was normal unt...

Introduction: Pituitary gigantism is a rare but clinically significant paediatric condition. Transphenoidal surgery is the treatment of choice, however medical treatment is often considered as adjuvant therapy.Case report: A 10.6 year old boy presented with tall stature. With hindsight he was noticeably tall from age 5 years. At 10 years his height velocity was 12 cm/year, prompting referral and further investigation. His height was 178.7 cm (+5.79 sds a...

Background: Pituitary apoplexy has been reported in around 2% of surgically treated adenomas. Around 45% of all pituitary tumours presenting with apoplexy are non-functioning ones (NFAs). Currently, no data exist on recurrence rates in patients with NFAs who have had classical apoplexy.Aim: We therefore, put together our data aiming to provide the first reliable series on recurrence rates in patients with NFA and classical pituitary apoplexy.<p class...

Background: To date, there is no consensus as to the gold-standard screening test for diagnosing Cushing’s Syndrome (CS).Objectives: This study aimed to: a) compare the ability of late-night salivary cortisol (LNSC) against overnight dexamethasone suppression test (ONDT) and urinary free cortisol (UFC) as screening test for pathological hypercortisolism (PH); b) test the performance of those tests in diagnosing Cushing’s disease (CD) or mild au...

The dexamethasone suppression test (DST) is a common screening test in Cushing’s syndrome but associated with false positive result in 10-20%. One cause of false positivity is inadequate dexamethasone absorption. An assay to measure serum dexamethasone concentration can be used to validate the accuracy of the DST result.Aims: To audit 1) Use of the dexamethasone assay in DSTs 2) How frequently dexamethasone levels are inadequate 3) ...

Introduction: Although acromegaly and pituitary gigantism have the same pathological cause, they have different disease characteristics.Aim: To study tumour size, treatment course and the most common comorbidities in a population with young-onset acromegaly.Materials and Methods: UK Acromegaly Register (UKAR, 22 centres, 1997-2017) retrospective analysis, enriched with patients from the FIPA-consortium. We defined gigantism as diag...
