38 year female presented to the endocrine clinic with palpitations. On further questioning she reported weight loss, diarrhoea but normal menstrual cycles. She was diagnosed in September 2022 with thyrotoxicosis in a country outside UK and was commenced on carbimazole 20 mg once daily. Blood investigations in September 2022- TSH 0.02 serum FT4 31.0 FT3 8.17). Bloods repeated by GP 4 months later after arrival in UK, showed the following: Serum TSH 23.45, serum T4 1.20, serum T...

Introduction: Tc99m-Sestamibi+I-123 subtraction using planar and SPECT-CT is commonly used to investigate PHPT. Our centre previously published sensitivity and specificity of 92 and 86% respectively for Tc99m-Sestamibi+I-123 subtraction. Five false-negative studies required neck exploratory surgery. One false-positive study incorrectly localised a PA which was not found in surgery (n=67). In recent years 4D-CT parathyroid has emerged as a useful technique to detect an...

Background: Approximately a third of pregnant women in the UK are Vitamin D deficient, which may confer deleterious consequences, including an increased risk of pre-eclampsia, gestational diabetes mellitus, and intrauterine growth restriction. Vitamin D supplementation in pregnancy has shown to be beneficial, including a reduced risk of pre-eclampsia and pre-term birth, compared to placebo. This audit investigated the extent to which women attending an ante-natal centre adhere...

Introduction: A biochemical profile of an underactive pituitary gland allied to visual field loss is commonly due to an underlying adenoma. We report a case where such a clinical picture was found but imaging/biopsy revealed a different cause.Case report: A 52-year-old Indian male was referred by his GP to an endocrine outpatient department with reduced visual acuity, balance problems and a biochemical profile of an underactive pituitary gland. Past hist...

Introduction: Thyrotoxicosis is a common condition referred to endocrine clinics. However, not all of them needed treatment with antithyroid medications. We report a case of thyroid hormone resistance due to a novel TSHRβ mutation who has been treated with subtotal thyroidectomy and antithyroid medications due to raised T4 levels.Case report: A 38-year-old south Asian woman was seen in orthopaedic clinic for elective right foot scarf oste...

The presentation of a patient with an adrenal tumour often causes diagnostic difficulty for the endocrinologist. Adrenal tumours are rare occurrences, particularly when large in size. We present two cases, where large adrenal tumours were found in inpatients on CT scanning and discuss the difficulties which arose in each case when attempting to obtain a definitive diagnosis. Case 1 A 38 year old Bangladeshi woman was being investigated for fevers, sweats and pancytopaenia. She...

Introduction: Radioiodine (RI) is a safe and effective treatment for Graves’ disease. In the months following RI different strategies are used to gain control of thyroid status, although there is no evidence base as to the optimal approach.Objectives: To compare the incidence of dysthyroidism post-RI between three principal management strategies employed by clinicians.Study design and methods: Retrospective, observational, mul...
