A 65-year-old man presenting with urinary symptoms was incidentally discovered to have an adrenal mass on imaging. Abdominal computed tomography (CT) revealed a 9.5 x 8 cm heterogenous solid right adrenal tumour with no evidence of metastatic disease. Family history included a brother who died from metastatic carcinoid and another brother who died from metastatic neuroendocrine tumour. The initial differential lay between adrenocortical carcinoma (ACC) or a pheochromocytoma. T...

Abstract: Idiopathic intracranial hypertension (IIH) is a devastating neurological condition, with elevated intracranial pressure of unknown aetiology. IIH is largely a disease of obese females of reproductive age. The clinical phenotype of IIH overlaps with polycystic ovary syndrome (PCOS), with prevalent obesity, hyperandrogenism and anovulation. In this study, we aimed to delineate the androgen excess phenotype of IIH women compared to those with PCOS and simple obesity. Wo...

Abstract: PCOS prevalence is reported to be increased in reproductive-age women with type-1 diabetes (T1DM) but measurement of androgens, crucial for diagnosis, has been with inaccurate immunoassays. No studies have been reported using liquid-chromatography-mass-spectrometry (LCMS). Reproductive-age T1DM women attending a single centre were evaluated for PCOS (NIH criteria). Women with T1DM and PCOS (T1/PCOS) were compared to T1DM women without hyperandrogenism (T1/no HA), and...

Abstract: The prevalence of hyperandrogenism has been reported to be increased in reproductive-age women with type-1 diabetes (T1DM). This observation however is based on findings using inaccurate immunoassays. No studies have been reported in diabetes using liquid-chromatography-mass-spectrometry (LCMS). We compared LCMS-measured androgens in T1DM-women with age-/ BMI-matched normal women, and compared findings with those in women with type-2 diabetes (T2DM) also compared to ...

Context: Patients with hypopituitarism have increased morbidity and mortality. There is ongoing debate around the optimum glucocorticoid replacement therapy.Objective: To assess the effect of glucocorticoid replacement in hypopituitarism on corticosteroid metabolism and its impact on body composition.Design and patients: We assessed the urinary corticosteroid metabolite profile (using gas chromatography/mass spectrometry) and body ...

Fluid restriction (FR) is the recommended first-line treatment for chronic hyponatraemia due to syndrome of inappropriate antidiuresis (SIAD) in expert guidelines, despite the lack of prospective data to support its efficacy. We aimed to test the hypothesis that FR was more effective than no treatment. 46 patients with chronic SIAD were randomised to either fluid restriction (1 litre/day, FR) or no specific hyponatraemia treatment (NoTx) for one month. Inclusion criteria were ...

Acromegaly is associated with increased morbidity and mortality. Surgery, radiotherapy (RT) and medical therapy are the treatment options to decrease GH and IGF-I concentrations to levels associated with cure or normalisation of mortality. We examined the response to dopamine agonists (DA) and somatostatin analogues (SSA) in 276 patients with acromegaly who received medical therapy during follow up (198 DA, 143 SSA). One hundred and seventy two had surgery and 73 RT prior to m...

Acromegaly is associated with increased morbidity and mortality. There are several treatment options for acromegaly including surgery, radiotherapy and medical therapy. The aims of treatment in patients with acromegaly is to achieve GH and IGF-I concentrations associated with cure or normalisation of mortality.We examined predictive factors of response to treatment with dopamine agonists (DA) and somatostatin analogues (SSA) in a cohort of 501 patients w...

Acromegaly is associated with increased morbidity and premature mortality which has been demonstrated in a number of retrospective studies reporting a standardised mortality ratio (SMR) between 1.3 and 3. Many patients with acromegaly develop hypopituitarism as a result of the pituitary adenoma itself or surgery and/or radiotherapy. Hypopituitarism is also associated with an increased SMR (1.2–2.17).Using the West Midlands Acromegaly database (n<...

Hypothalamic-pituitary (HP) dysfunction is common in children treated with cranial radiotherapy (RT) for brain tumours but there is little known about the risk of HP dysfunction in adults treated with RT for primary non-pituitary brain tumours.We aimed to investigate the frequency of HP dysfunction in adults after RT for primary brain tumours which are distant from the HP region.We studied 56 adult patients who received external be...
