Introduction: Hypothyroidism in pregnancy may be associated with neurodevelopmental delay of the unborn baby. Timely management of abnormal thyroid function tests (TFTs) in pregnancy is important. In our centre, some patients attend an Endocrinology-led dedicated antenatal thyroid clinic, whilst others attend an Obstetrician-led general antenatal clinic.Objectives: The management of hypothyroid pregnant patients attending our centre was audited against T...

Pituitary apoplexy (characterised by sudden onset headache, meningism and cranial nerve defects) is an unusual but serious complication of pituitary macroadenoma. Less than 2 percent of patients with pituitary macroadenoma present initially with apoplexy. Pituitary adenoma is the presenting feature in 10–25% of cases with multiple endocrine neoplasia (MEN) type 1, with microadenomas accounting for 2/3 of MEN-related pituitary adenomas.A 35-year-old ...

Factitious thyrotoxicosis secondary to Levo-thyroxine accounts for approximately 0.3% of all cases of hyperthyroidism. Although recognised as a cause of thyrotoxicosis, there are no peer-reviewed published cases of thyrotoxicosis secondary to ingestion of Tri-iodothyronine.A 23-year old lady presented to endocrine clinic with a 6-month history of palpitations, heat intolerance and tremor. She had a history of PCOS and reported difficulties with weight co...

The multiple endocrine neoplasia (MEN) clinic at our hospital was established in 2002 with the aim of providing integrated, comprehensive and expert regional care to patients with MEN syndrome. The clinical team consists of an adult endocrinologist, a paediatric endocrinologist, a clinical geneticist and an endocrine surgeon.In 2002, 16 patients with MEN type 1 from five different kindred were seen. These patients had previously been attending a combinat...

Introduction: Adult Growth Hormone Deficiency (AGHD) is associated with osteoporosis. Underlying mechanisms involved in the pathogenesis include reduced target-organ sensitivity to the effect of PTH. Growth Hormone Replacement (GHR) in AGHD leads to increased PTH target-organ sensitivity and consequently increased bone turnover and bone mineral density (BMD).Aims: We determined the effect of alendronate, given in addition to GHR, on PTH target-organ sens...

Background: Adult growth hormone deficient (AGHD) is associated with reduced bone turnover and reduced bone mineral density (BMD): factors improved by growth hormone replacement (GHR). Obesity is associated with reduced bone turnover but increased BMD. We investigated the impact of body mass index on parathyroid hormone (PTH), phospho-calcium metabolism and bone turnover in AGHD patients before and after GHR.Study design: Of 31 AGHD patients (15 obese pa...
