Background: Phaeochromocytomas (PC) are rare tumours of chromaffin cells which may present with relatively common and non-specific symptomatology. The optimal biochemical investigation to confirm or refute the diagnosis remains unclear; some centres use fractionated plasma metanephrines, which are very sensitive but lack specificity, while others use conventional measurements of urinary metanephrines, which may be affected by concurrent drug administration and are less sensiti...

Hemoglobin A1c (HbA1c) is used for the long-term management of patients with diabetes mellitus (DM). Hemoglobin variants other than HbA1c and e-N-lysine-glycated HbA0 may cause analytical interference in determinations of HbA1c. Hemoglobin J is an abnormal hemoglobin, an alpha globin gene variant and present in various geographic locations. Hemoglobin J (depending on its type) has different characteristics and functions. For example hemoglobin J Capetown (α2 92Gln β2...

Objective: To investigate the results of J – 131 treatments in patients (pts) with autonomous thyroid adenomas in long period of follow up.Material and Methods: We enrolled 68 consecutive pts with Plummer’s disease (50 females, 18 males, mean age 54,7 yrs, range 21 – 79 yrs) for period 2000 – 2020 yrs. 87%(59/68) pts had a unifocal nodule, while 13% (9/68) pts had multifocal toxic autonomous nodules. Pts stopped antithyroid drugs for ...

J J Kopchick, Ohio University, Athens, Ohio, USA. AbstractDr John J Kopchick is an internationally recognized leader in the growth hormone (GH) field. Since 1987, he has held the Milton and Lawrence H Goll Eminent Scholar Professorship in Molecular and Cellular Biology and directs the Growth/Obesity/Diabetes Section of the Edison Biotechnology Institute at Ohio University in Athens, Ohio. He also is Professor in the B...

Oncogenic activation of MAPK in thyroid cells leads to loss of expression of genes required for thyroid hormone biosynthesis, including the sodium iodide transporter (NIS) and thyroid peroxidase (TPO). Tumors with BRAF mutation have lower expression of NIS, explaining in part why BRAF-mutant PTCs are often resistant to RAI therapy. We developed mouse models of thyroid cancer driven by BRAFV600E, and these tumors also lose the ability to concentrate radioiodine, whic...

J Wass, Department of Endocrinology, OCDEM, Churchill Hospital, Oxford, UK AbstractJohn Wass is the Professor of Endocrinology at Oxford University and Head of the Department of Endocrinology at the Oxford Centre for Diabetes, Endocrinology and Metabolism, Churchill Hospital Oxford, UK. He qualified at Guy’s in 1971 and did his endocrine training at Bart’s. He got his MD from the University of London in 1980....

J Connell, University of Glasgow, Glasgow, United Kingdom Abstract John Connell graduated in medicine from the University of Glasgow (with commendation) in 1977. After initial general medical training he was appointed Registrar in Endocrinology in the Western Infirmary, Glasgow; in 1983 he became Clinical Scientist within the MRC Blood Pressure Unit and Senior Registrar in Endocrinology. In 1986 he was awarded a ...

There is no doubt that the use of a syringe and needle has led to an important cost effective strategy for the investigation of thyroid nodules by fine needle aspiration biopsy (FNAB) with cytological examination of the aspirate. A recent European Thyroid Association survey found that 99% of respondents used FNAB (Bennedbaek et al 1999). However, there are limitations of FNAB including false negatives, false positives, inadequate specimens and reporting, accessibility of nodul...
