We have previously (Allehabadia et al., JCEM, 2001) reported better cure rates for patients treated with a single fixed dose of 370 MBq 131I compared with 185 MBq. We have since increased the standard dose of administered radioiodine to 600 MBq and re-audited our data in 1240 consecutive thyrotoxic patients. We aimed to compare the efficacy of the new dose regimen and to explore factors that might predict outcome. Patients were categorised in 3 diagnostic gro...

We have previously shown PTTG and PBF to be over-expressed in differentiated thyroid cancer and to be prognostic indicators for recurrence. Subsequently we reported PBF to be a transforming gene in vitro and tumourigenic in vivo. Since over-expression of PTTG results in the same findings, we examined whether PBF-induced tumourigenesis was an independent effect, or else a result of increased PTTG activity. Two HA-tagged mutants of PBF were generated, firstly subst...

During mitosis, temporal release of separase from its inhibitor securin results in cohesin cleavage, thereby promoting anaphase. The developing fetal brain has rapidly proliferating neuronal cells whilst adult neurons no longer proliferate. When comparing 61 fetal and 12 adult human brain samples, we found significantly increased separase mRNA and protein throughout ontogeny and reduced securin expression in fetal brain compared with adult. Using MTT assays, we examined the ef...

1500 euthyroid patients (1302 females and 198 males, mean age 47.8) presenting with thyroid enlargement were evaluated by fine needle aspiration (FNAC) of the thyroid as the first line investigation. The final cytological or histological diagnosis was determined after surgery (n=556) or clinical follow-up for a minimum period of 2 years (mean 9.5 yrs, range 2-19 years). Goitre type was assessed clinically and classified as diffuse in 184, multinodular in 457 or solitary nodule...

Introduction: Ectopic ACTH syndrome (EAS) is a rare condition, accounting for approximately 10% of all Cushing’s syndrome (CS). We assessed the experience managing this condition in our centre.Methods: 171 patients (105 female, 66 male) with elevated plasma ACTH concentrations were identified from local IT systems at a tertiary centre (University Hospitals Birmingham NHS Foundation Trust) between 2002 and 2015. An electron...

Background: Maternal severe iodine deficiency has been associated with pregnancy and neonatal loss but the impact of mild-moderate iodine deficiency on pregnancy is not well-documented. Mild-moderate iodine deficiency during pregnancy is common even in iodine replete countries. In the UK women of reproductive age have been found to be mildly-to-moderately iodine deficient. UI/C is an optimal indicator for iodine status in pregnancy.Aims: We...

Background and aims: Thyroid peroxidase antibody (TPOAb) positivity is prevalent in women of reproductive age and pre-disposes to thyroid dysfunction, namely hypothyroidism, which has adverse effects on pregnancy. The aim of this study was to report the rate of development of abnormal thyroid function among initially euthyroid TPOAb positive women recruited into TABLET trial. To also identify factors associated with the development of hypothyroidism and to compare outcomes bet...

Thyroid dysfunction and autoimmunity are associated with adverse fertility and pregnancy outcomes. International bodies recommend routine thyroid function screening in women with history of subfertility or miscarriage. Knowledge about the frequency of, and risk factors for, thyroid disease is limited in the asymptomatic preconception population. A prospective multi-centre study of women with history of miscarriage or subfertility conducted at 49 hospitals across the United Kin...
