Aim: To determine whether cases of hypocalcaemia presenting via an emergency medical admissions unit (EAU) are appropriately investigated.Background: Hypocalcaemia is a potentially life threatening abnormality, with a prevalence of 18% among hospital inpatients.1,2 Risk factors include vitamin D deficiency, renal disease, hypoparathyroidism (typically post-neck surgery) and hypomagnesaemia. A reasonable investigational dataset comprises U+Es a...

MM, a 51-year-old female was reviewed in the Endocrinology clinic for the assessment of hypercalcaemia, hyperprolactinaemia, and an adrenal mass. Bipolar depression had been diagnosed 24 years previously with continuous use of Lithium Carbonate since. An acute deterioration in mental state 3 years previously prompted Risperidone treatment which was ongoing. Hypercalcaemia (calcium=2.78 mmol/l, PTH=13.8 pmol/l, vitamin D=33 nmol/l) was recorded. Polyuria and nocturia was noted....

Aim: To present a case of severe primary hyperparathyroidism (PHPT) manifested predominantly with polyuria.Case: A 53 years old caucasian female presented to the emergency room with polyuria (5-6 l), and increasing during last 4 weeks dehydration, weight loss (10 kg), weakness, confusion. Diabetes mellitus and insipidus had been excluded. After hypercalcemia (3.6–3.9 mmol\l), Ca++ to 2.0 mmol\l and PTH of 616 pg\ml (11–62) were revealed acute P...

The injectable contraceptive depot medroxyprogesterone acetate (DMPA, Depo-Provera®) is used by over nine million women worldwide. It induces amenorrhoea, raising concern about effects on bone density. This study aims to ascertain if the skeletal effects of DMPA are age-specific and to identity the mechanisms through which DMPA acts on the skeleton. The study was approved by the local Ethics Committee. We recruited 100 pairs of women ages 18–25 and 35&#150...

41 year old male presented in 1992 with 2 years history of blurring of vision, headaches, dizzy spells. Had Right supratemporal visual field defect, pituitary MRI which showed cystic pituitary lesion. Had TSS in May 1992 and histology showed Rathkes pouch cyst. Post operatively developed DI and started on DDAVP.SST,TRH and GnRH tests were normal. Persisted retro orbital head aches, developed nasal and temporal field loss. MRI in Sept 1992 showed large intrasellar recurrence of...

Objective: Our aim was to identify and treat sleep disorders in asymptomatic patients with craniopharyngioma and to identify co-existing respiratory disease.Methods: 5 patients (1 male) with a diagnosis of craniopharyngioma, were identified from the local pituitary database and admitted for polysomnography (Alice 4, Respironics), as part of a study of hypothalamic disease in craniopharyngioma. Sleep disturbance was defined as an apnoea index (AHI) of &#6...

Progressive osseous heteroplasia (POH, MIM 166350) is a rare autosomal dominant disorder characterised by extensive dermal ossification during childhood, followed by widespread heterotopic ossification of skeletal muscle and deep connective tissue. Recently, genetic basis was found to be common with Albright’s hereditary osteodystrophy (AHO) (Shore et al., 2002): paternally inherited inactivating mutations of the GNAS1 gene were found. GNAS1 is the ge...

Case History: A 52 year old man presented in 2009 with a gradual loss of peripheral vision associated with headaches. Examination confirmed bi-temporal hemianopia. Further investigation revealed elevated prolactin levels and pituitary MRI showed evidence of large pituitary tumour. A diagnosis of macroprolactinoma was made and cabergoline was commenced. Given resistance to medical treatment, the patient required two surgical resections (2011 and 2013) and radical radiotherapy (...

Background: Osilodrostat is an oral inhibitor of 11β-hydroxylase (CYP11B1), the enzyme that catalyses the final step in cortisol biosynthesis. In a 22-week, phase II study, osilodrostat treatment normalised mean urinary free cortisol (mUFC) in 78.9% (15/19) of patients with uncontrolled Cushing’s disease and was well tolerated. The present phase 3 study is designed to confirm the safety and efficacy of osilodrostat in patients with uncontrolled Cushing’s disease...

Background: Hypocalcaemia is a common electrolyte disorder and it can occur following parathyroidectomy or thyroidectomy. It has been suggested that some post-operative hypocalcaemic crises may reflect severe vitamin D deficiency and vitamin D supplementation may have a protective effect.Objectives: To establish the prevalence of severe post-operative hypocalcaemia (as defined by the requirement for i.v. calcium gluconate) following parathyroid surgery a...
