AbstractNon-functioning pituitary adenomas (NFPAs) are the most common pituitary tumours, often presenting with chiasmal compression or hypopituitarism. Surgical resection, accompanied by radiotherapy (RTX) in selected cases, is the treatment of choice for compressive tumours. Long-term health consequences of NFPAs and their treatment are unclear. In this retrospective study, we aimed to assess long-term pituitary function, recurrence and mortality in a ...

Lithium is used in psychiatric practice as maintenance therapy in bipolar disorder. It has a narrow therapeutic index with serious toxic potential. Lithium is associated with multiple endocrine and metabolic disturbances but data regarding the rates of these in individual patients is lacking. In a tertiary referral centre, all patients on lithium therapy from 2000 to 2014 were identified. The aim of this study was to assess the impact of lithium therapy on the development of e...

Non-functioning pituitary adenomas (NFPAs) are the commonest subtype of pituitary tumour. Surgical resection, accompanied by radiotherapy (RTX) in selected cases, is the treatment of choice for compressive tumours. Long-term health consequences of treatment for NFPAs are unclear. In this retrospective study, we assessed long-term pituitary function and mortality rates in a large NFPA cohort across two tertiary centres in the UK and Ireland.Case-note revi...

Background: Distress tolerance (DT) has been proposed as a possible contributor to the ability to successfully adhere to difficult behaviour changes, such as stopping problematic substance and cigarette use. A number of measures of DT have been used in attempts to predict behaviour change outcomes. Findings however, have been inconclusive and no one measure has shown consistent results. Importantly, no work has yet assessed the predictive value of DT measures in successful wei...

Introduction: Childhood papillary thyroid carcinoma (CPTC), despite bilateral thyroidectomy (BT), nodal resection and radioiodine remnant ablation (RRA), recurs within neck nodal metastases (NNM) in >30% within 20 postoperative years. However, these NNM are usually treated with re-operation or further radioiodine; US-guided ethanol ablation (EA) may be considered (j.sempedsurg.2020.150920) for patients with limited numbers of NNMMethods: We studied l...

Primary hyperparathyroidism (PHPT) is a common endocrine disorder with a prevalence of 0.86% in Europe. Approximately 10% of cases are hereditary. Syndromic PHPT occurs as part of multiple endocrine neoplasia (MEN)1, MEN4, MEN2A and hyperparathyroidism jaw tumour syndrome. Non-syndromic causes include familial hypocalciuric hypercalcaemia. Establishing the underlying genetic cause allows for targeted, cost effective management. Current guidelines recommend that genetic testing...

Primary hyperparathyroidism (PHPTH) is a common endocrine disorder and it is estimated that 10% of cases are hereditary, related to syndromes including; multiple endocrine neoplasia (MEN) type 1, MEN type 4, MEN2A and hereditary hyperparathyroidism jaw tumour syndrome. Further hereditary cases can occur in the absence of syndromic features such as familial hypercalcemia hypocalcuria. Identifying cases of hereditary PHPTH enables a personalised medicine approach. Current guidel...

Hyponatraemia is commonly encountered in neurosurgical units. Salt wasting syndrome is rare, and thought to occur due to ANP- and BNP-mediated natriuresis, leading to hypovolemic hyponatraemia. A 31 year old male was transferred to the National Neurosurgical Unit with a 12 hour history of back pain, progressive lower limb weakness and sensory loss. MRI demonstrated an epidural haematoma, extending from C7 to T3, and he underwent emergency decompressive laminectomy. Vasopressin...

Transsphenoidal surgery (TSS) to resect a corticotroph adenoma is the first-line treatment for Cushing’s disease (CD); remission rates of up to 80% have been reported in cases of microadenomas. Endocrine Society guidelines define post-operative biochemical remission as morning serum cortisol <138 nmol/L within seven days of surgery. Our practice is to use a cut-off of <50 nmol/L at day 3 post-op to indicate biochemical remission. If serum cortisol on day 3 is 50&#...

Idiopathic Isolated ATCH deficiency (IIAD) is a rare cause of secondary adrenal insufficiency characterised by ACTH deficiency with otherwise intact pituitary function. Our objective was to describe the presentation, the autoimmune associations and diagnostic findings observed in IIAD. We present a case series of 19 cases of idiopathic Isolated ACTH deficiency which were identified from the National Pituitary Register in Ireland. A chart and biochemical review was performed to...
