Non-neoplastic pituitary stalk thickening is rare in patients without infiltrative disorders and diabetes insipidus. We present a non-diabetic patient with end stage renal failure with hyperprolactinaemia and pituitary stalk thickening.A 53-year-old Nigerian gentleman presented with reduced libido, erectile dysfunction and painful gynaecomastia. He denied galactorrhea, headaches or visual disturbances. He previously received spironolactone for resistant ...

Somatostatin analogues (SSA) have an established role in the medical management of patients with neuroendocrine tumours (NETs). They are effective in the symptomatic treatment of some metastatic NETs and may also provide tumour stabilisation or reduction. We report two patients with disease progression who benefited from SSA. Mrs HW, 64-year old woman, was diagnosed with a grade 1 small-bowel NET with lymph node and liver metastasis in 2012: Ki-67 index < 1%. Despite a seg...

We report the case of an 82-year-old lady who was admitted with hypercalaemic crisis (adjusted Calcium 4.82 mmol/L) and acute kidney injury (creatinine 169 micromol/L). PTH was 295 pmol/L, raising the suspicion of an underlying parathyroid carcinoma. She had no palpable neck mass. Her ALP was 131 IU/L and Vitamin D 73 nmol/L; myeloma screen was negative and chest radiograph showed no pathology. A DEXA scan revealed osteoporosis. The hypercalcaemic crisis...

A 22-year-old female first presented in 2008 with a six-month history of galactorrhoea and irregular menses. She had hyperprolactinaemia (2401 mIU/L), a negative macroprolactin screen and her pituitary MRI scan demonstrated a 4 mm microadenoma. Her cannulated prolactin levels were >1500 mIU/L. TFTs, IGF-1, cortisol and remaining pituitary profile were within normal range.Cabergoline was commenced and gradually i...

Case history: A 22-year-old female first presented to our endocrine clinic in 2008 with a six-month history of galactorrhoea and irregular menses.Investigations: She had hyperprolactinaemia (2401 mIU/l), a negative macroprolactin screen and her pituitary MRI scan demonstrated a 4-mm microadenoma. Her cannulated prolactin levels were >1500 mIU/l. She had reverse FSH:LH ratio hence the possibility of PCOS was considered. Her pelvic ultrasound did not s...

Background: Surgery has a significant role in the management of benign thyroid disease, necessitating pre-operative evaluation and appreciation of possible complications. These include hypoparathyroidism and hypothyroidism. We compared outcomes of our benign thyroid disease patients requiring surgery to national standards set by the British Thyroid Association.Method: Outcomes for patients operated between December 2010 and December 2012 with benign dise...

Generously supported by IPSEN)-->Moderate hyperprolactinaemia (<1000 mU/l) is a common abnormal biochemical finding in patients with end-stage renal failure (ESRF). The underlying pathophysiological mechanism is thought to be due to a combination of increased prolactin secretion as well as delayed renal clearance. There are no current clear guidelines for the treatment of ESRF-induced symptomatic hyperprolactinaemia but renal tra...

Background: Circulating levels of total oestradiol (E2) decrease with age in adult males; the effect of altered E2 circadian rhythm is uncertain. We hypothesised that age-related changes in the circadian rhythm contribute to decreased BMD in older males and investigated this.Methods: Nineteen subjects were studied: six young-healthy (YH) males (mean age (years) 27.3±4.6) with normal BMD, eight older-healthy (OH) males (mean age...
