Case history: 63 year man with two trans-temporal incomplete resections of a glomus jugulare tumour (HNPGL) in 1993 and 2000 with regular surveillance scans for residual disease. Eight years later, an MRI demonstrated an incidental pituitary macroadenoma with cavernous and sphenoid sinuses invasion. The patient was asymptomatic but, his biochemistry revealed a markedly raised prolactin of 43,000 mIU/l with no other pituitary hormone deficiency. Cabergoline was commenced and th...

The continuous glucose monitoring system (CGMS) have recently been developed for use in diabetes to provide comprehensive blood glucose data around the clock during normal activities. We have demonstrated for the first time that CGMS can assist in the management of 2 patients with confirmed insulinomas. We present 2 female patients (aged 41 and 35 years) with symptoms suggestive of hypoglycaemia. Both had biochemical evidence of insulinoma with hypoglycaemia, hyperinsulinaemia...

The results of transsphenoidal surgery for acromegaly by a single neurosurgeon (MP) operated between 1981 and July 2002 were examined retrospectively. 141 database and case note records for patients with a clear pre-operative diagnosis of acromegaly were reviewed. Patients with incomplete pre- or postoperative data on growth hormone (GH) status were excluded from further analysis (n=14). The remaining 127 formed the audit group.Pituitary imaging data was available in 84 of...

Pituitary apoplexy is a rare condition caused by haemorrhage or infarction into a pituitary tumour. The majority of patients do not have any identifiable triggering event, although situations altering the blood flow to the pituitary gland and pre-existing systemic hypertension have been identified as potential causal factors.We retrospectively reviewed the presentation and outcome of 15 patients with pituitary apoplexy (8 men, 7 women; age 16-87, mean 5...

We examined the results of treatment of adult Cushing's disease by transphenoidal surgery by a single neurosurgeon (MP). Patients with Nelson's syndrome and those who previously had received treatment for Cushing's by a different surgeon were excluded. We reviewed the pituitary database and patient records for all patients operated between 1988 and 2000 with clear pre-operative evidence of Cushing's disease. 117 patients had clear evidence of a pituitary source of excess ACTH....

The ACTH receptor (ACTH-R) is the second member of the melanocortin receptor family that includes five seven-transmembrane G protein-coupled receptors, and has been shown to be predominantly expressed in the adrenal cortex. It has been postulated that ACTH may regulate its own secretion through ultra-short loop feedback within the pituitary, and as ACTH-secreting adenomas are characterised by resistance to glucocorticoid feedback, they may also have dysregulated ACTH feedback....

Introduction: Familial isolated pituitary adenoma (FIPA) and young-onset sporadic pituitary adenoma patients are suggested to be screened for mutations in AIP, a gene described in 2006 and amenable to UK testing since 2008.Methods: affected subjects have been tested in Exeter and Oxford genetic laboratories. Data were collected from 120 FIPA-families and 193 sporadic cases with young-onset disease (<30y) from 49 centres in the UK. The Mann&#...
