Until 12th week of gestation foetus is entirely dependent on maternal thyroxine. Inadequate thyroxine replacement may lead to lower IQ of offspring and also an increased miscarriage rate.We audited 68 hypothyroid pregnant females to assess whether management of their thyroid status had met current standards. In the first trimester TSH is not an optimal monitoring marker as it is supressed by rising HCG level. According to established clinical guidelines ...

Background: Following the advent of thyroid function screening and highly sensitive TSH assay subclinical hyperthyroidism (SCHT) is becoming increasingly common. No audit addressed the treatment outcome of this group of patients.Methods: Prospective analysis of management outcome of patients seen in endocrine clinic over 36 months was carried out. 46 patients who presented with SCHT were included, of whom 41 had confirmed SCHT on repeat testing.<p cl...

Case history: A 74-year old gentleman was referred from Urology clinic for hypercalcemia after being treated for left vesico-ureteric calculus causing mild hydronephrosis. Past medical history included asthma, eczema and hypertension. He had been taking calcium supplements for 5 years, but stopped 2 months prior to clinic. He was asymptomatic and quite well with no recent fracture.Investigations: Adjusted Ca ranged from 2.62 to 2.78 mmol/l, PTH from 2.6 ...

Introduction: Radioactive iodine (RAI) is an effective and widely used treatment for thyrotoxicosis. Post-radioiodine thyrotoxicosis is a well-known side effect of RAI. This is usually mild and easily controlled mostly with beta blockers but sometimes needs anti-thyroid drugs (ATD).Aim of the study: To assess the incidence and predictors of post-radioiodine thyrotoxicosis.Methods: Retrospective analysis of 86 patients who had RAI t...

Aims: To define and identify patients who have ‘failed’ parathyroidectomy by a single surgeon. To explore common features of these cases to refine our pathways.Methods: This case note review began with a retrospective audit of 123 patients having neck exploration from January 2009 to May 2014. The dataset of clinicopathological information obtained from the electronic Trust records, was interrogated to identify patients fulfilling the following...

Aim: Short Synacthen test has been widely used screening test for assessment of hypothalamo-pituitary-adrenal axis (HPA). The most widely used is 30 min plasma cortisol Post synacthen. We have compared 30 min cortisol with 60 min for assessment of the HPA axis of patients with known endocrine disorders and on long term steroid, opiate use and obesity (non endocrine disorder).Method: Cortisol Response to 30 and 60 min post synacthen were measured in rando...

Background: While few hypothyroid patients require more than the expected weight related dose of levothyroxine, the underlying causes of larger-than-expected dosing requirements have not been studied in a single cohort. Our aim was to determine and quantify the multiple factors contributing to high dose levothyroxine requirements in a cohort of patients with hypothyroidism.Methods: The Grampian Automated Follow-Up Register (GAFUR) monitors around 17 500 ...
