Adipsic diabetes insipidus (ADI) is a rare condition which has been reported following clipping of anterior communicating artery aneurysms, craniopharyngioma and brain trauma, but not with pituitary adenoma. We report a case of ADI following surgery for a pituitary macroprolactinoma. A 14-year-old boy presented with bitemporal hemianopia due to a large macroprolactinoma. Two debulking surgeries were performed without the development of diabetes insipidus. Following a third rad...

Aminobisphosphonates impair osteoclast cell function and reduce bone remodelling rate. It has been speculated that atypical femoral fractures in patients on bisphosphonates are the result of impaired bone remodelling.The primary aim of this prospective study was to assess levels of bone remodelling in patients with osteoporosis on aminobisphosphonate therapy by measurement of bone turnover markers. The secondary aim was to assess the adequacy of concomit...

The Endocrine Society Guidelines 2016 recommend the Aldosterone Renin Ratio (ARR) to screen for Primary Hyperaldosteronism (PHA), yet we perceive low rates of referral to our service for such patients. Here we report a retrospective audit of ARR measurements requested through Regional Hospital Mullingar 01/01/2023 – 31/12/2023. ARR results were obtained directly from the referral laboratory. An assay specific ARR threshold >25 (ARR+) indicates possible PHA. We reviewe...

Published data has demonstrated that low 0900 h plasma total cortisol (PTC) immediately following traumatic brain injury (TBI) predicts mortality. However, potential discrepancies exist between PTC and plasma free cortisol (PFC). We hypothesised that low PTC would correlate closely with PFC and predict mortality and long-term hypopituitarism.One hundred patients (84 men, median age 33, range 18–75) with TBI (mean GCS±S.D.=8.59&#1...
