Introduction: 99m/Tc-MIBI parathyroid scintigraphy (MIBI) is the most common test used for pre-operative localization of parathyroid adenoma in primary hyperparathyroidism. We evaluated the influence of serum calcium and parathyroid hormone (PTH) levels on sensitivity of MIBI imaging in successful parathyroid localisation in patients identified as having primary hyperparathyroidism.Methods and material: Retrospective review of 403 patients who had MIBI s...

Background: Bone is constantly remodelling and an imbalance between bone resorption and formation can predispose to osteoporosis. Bone turnover markers (BMTs) are biochemical markers that reflect the dynamics of bone formation and resorption. Carboxy-terminal collagen crosslinks (CTx) is a bone resorption marker measured in serum which is used to monitor treatment response.Aims: The aims of the study were to determine how CTx has been used to monitor pat...

Introduction: Non-Hodgkin lymphoma (NHL) involving the hypothalamus and pituitary gland is rare. Central nervous system involvement by NHL may be either as a primary tumour or from systemic lymphoma. We report an interesting case of aggressive central nervous system (CNS) lymphoma presenting as pituitary macroadenoma.Case report: A 67-year-old Caucasian woman presented with sudden onset of left eye ptosis and diplopia. Examination showed left third nerve...

Background: NICE guidelines (NG18) state that paediatric patients aged <18 years old with suspected diabetes mellitus (DM) should be immediately referred to specialist care to confirm diagnosis and provide immediate treatment. The Nottingham University Hospitals (NUH) Paediatric Endocrine team advise primary care to investigate suspected hyperglycaemia using a POCT (point of care testing) glucose meter at the primary care facility to avoid the delay incurred by sending a s...

Introduction: Androgens have long been known to play an important role in health and wellbeing. A range of clinical disorders in males and females can arise due to disruption to production and action of androgens. Androgen receptor (AR) is widely expressed throughout the adrenal cortex, yet the wider role for androgen signalling in the adrenal remains underexplored due to the lack of suitable animal models.Methods: An adrenal-specific androgen receptor k...

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...

We developed an improved process for producing high quality 67Cu using an electron accelerator instead of a high energy proton accelerator. The beta/gamma emitting radioisotope 67Cu was created using the (g,p) reaction on isotopically enriched 68Zn target (nominally 40 g, 98% enrichment). The high energy photons were produced by bremsstrahlung conversion of electrons from a 45 MeV electron LINAC. A specially designed water cooled converter, end...

Background: Assessment of psychological burden of disease forms one criterion for accreditation of a cancer specialist center. Patient Health Questionnaire-4 (PHQ-4), a validated self-report ultra-short questionnaire was used to assess anxiety and depression level in patients with GEP NETs, attending the clinics at an ENETS Centre of Excellence.Methods: PHQ-4 was completed during routine outpatient visits over a three month period by 48 patients, who wer...

Background: Isolated pituitary stalk (PS) lesions/thickening detected on imaging pose challenging dilemmas.Aim: Audit the diagnostic approach and management of patients with isolated PS lesions/thickening reported on MRI in a tertiary hospital.Methods: Reports of pituitary/brain MRIs performed in our Radiology Department between 1/2013 and 12/2015 were searched for the terms ‘stalk’, ‘infundibular’, ‘infund...
