We report two cases of seizures resulting from severe electrolyte imbalance.Case 1: A 48-year old lady with CREST syndrome and oesophageal dysmotility. She was admitted with diarrhoea and vomiting. Routine investigations including FBC, U&E, LFT, and CRP were normal. She later complained of pins and needles in her hands and around her mouth. Twenty-four hours later, she developed blurred vision, neck pain and generalised ache, was found drowsy, with p...

Introduction: We present 3 cases of the same severe electrolyte imbalance presenting with acute neurological symptoms.Case descriptions: Case A, a 48 year old lady with severe CREST syndrome presented with prolonged vomiting and diarrhoea. Initial investigations showed: Sodium 141 mmol/l, Potassium 3.2 mmol/l, Creatinine 53 mmol/l, Glucose 4.3 mmol/l, Haemoglobin 13.9 g/dl, Albumin 38 g/l. 2 days after admission she developed seizures. Case B, a 75 year ...

Objective: Propylthioracil (PTU) when given long term has recently been implicated in the development of antineutrophil cytoplasmic antibody (ANCA) related systemic vasculitis. We describe a case of ANCA positive athropathy induced by long term PTU therapy. Methods: Assessment was based on patient's symptoms, signs, serum markers and treatment outcome as revealed by case notes and patient review. A Medline search for PTU related vasculitis was also performed. Results: A 27-yea...

We report 28 patients (21M 7F; 17-86y) with pituitary apoplexy presenting between 1988 and 2004. Presenting features included: headache in 25 patients, 'collapse' in 3, vomiting in 13, complete blindness in 4, decreased visual acuity in 13, visual field loss in 12 and ophthalmoplegia in 16. Only 4 had no initial visual deficit. Predisposing factors included a known pituitary tumour in 4 patients, anticoagulant therapy in 3 patients and ITP in 1 patient. CT was initial imaging ...

Introduction: Accumulating evidence suggests an association of vitamin D with insulin resistance (IR) in women with polycystic ovary syndrome (PCOS). The role of PTH in insulin metabolism is less clear. We aim to study the association of PTH and 25-hydroxyvitamin D (25(OH)D) levels with metabolic and endocrine parameters in a cohort of PCOS women.Methods: We measured PTH and 25(OH)D levels in 544 PCOS and 139 healthy control women within the same age ran...

Introduction: Pheochromocytomas represent rare but potential lethal tumors arising from the adrenal medulla. Early recognition and diagnosis represent a challenge due to the non-specific character of signs and symptoms. The classic presentation includes headache, sweating, palpitations and other signs and symptoms of apparent catecholamine excess occurring in paroxysms. Sympathomimetics may result in a similar presentation, potentially complicating the diagnosis.<p class="...

Background: Transformation of the South Wales NET service in late 2017 introduced new specialised staff, gastroenterology-led clinics and MDTs with a particular emphasis on educating referring specialties on NETs. Data has shown patient experience, satisfaction rates, quality of life and gastrointestinal symptom scores have all improved. This study aims to describe findings from new NET service data for: referrals into the service, diagnosis times after symptoms, and initial s...

Pituitary apoplexy (PA) is a rare clinical syndrome related to abrupt hemorrhage and/or infarction of the pituitary gland, usually occurring in patients with preexisting pituitary disease. It is an endocrine emergency requiring rapid diagnosis and appropriate management. Pituitary apoplexy may lead to multiple pituitary hormone deficiencies. Without proper diagnosis and management, these can lead to the occurrence of irreversible complications, most significantly adrenal crisi...

Background : Adrenocortical cancer (ACC) is a very rare but aggressive tumour with annual incidence of 2 cases per million populations. Hypercalcaemia is a commonly encountered paraneoplastic manifestation of certain cancers such as lung, breast, kidney, gynaecological and neuroendocrine tumours but very rare in ACC. So far, there are only two cases of ACC and PTHrP-related hypercalcaemia reported in the literature.Case report: 32-year-old man presented ...

Introduction: Premature ovarian insufficiency (POI) is a rare cause of primary amenorrhea (1,2). We report a 16-year-old girl with normal secondary sexual characteristics, but no menses due to an autoimmune POI and associated with autoimmune gastritis. This is the first report of such constellation in an adolescent – both conditions separately already being rare in the pediatric population.Case presentation: A 16-year-old girl was referred to our de...
