BACKGROUND The aim of the study was to achieve an effective target dose in the thyroid by increasing the effective half-life (Teff) of (131)I by use of iodide ((127)I) two days after (131)I therapy in patients with hyperthyroidism with low Teff. MATERIAL AND METHODS The study was carried out in two groups. Group A - 41 patients, and Group B - 14 patients, all the patients were with hyperthyro...

Three groups of patients who had undergone subtotal thyroidectomy for Graves's disease, toxic multinodular goitre, or euthyroid multinodular goitre 12 to 15 years before and in whom a normal serum thyroxine (T-4) level was found were each divided into two subgroups on the basis of a normal or a raised serum thyrotrophin concentration. There was no difference in mean serum T-4 concentration betw...

OBJECTIVE Epidermal growth factor (EGF) is believed to be one of the most potent growth factors for the thyroid gland. DESIGN AND METHODS We tested plasma EGF concentrations (radioreceptor method) in patients with non-toxic nodular goitre (NNG). Blood samples from patients with NNG were collected on the day before the surgery, during subtotal thyroidectomy (sTx)--from peripheral and thyroid v...

In order to compare the effect of propylthiouracil (PTU) of Iran Hormone Co. and that of Dr. Herbrand KG, Germany, 28 patients with toxic goiter entered this study. Each patient received 200 mg PTU daily for the first 4 weeks and 50 mg daily thereafter. 17 patients received PTU from Iran Hormone (group 1) and 111 took PTU from Germany (group 2). T4, T3 and TSH by RIA and resine T3, uptake were ...

The levothyroxine suppressive efficacy in benign thyroid nodules treatment is well described in uninodular non-toxic goiter, whereas only few controlled trials enrolled patients with multinodular disease. The aim of the present study is to evaluate the short term effects of levothyroxine treatment in never treated, pre-menopausal women affected by thyroid multinodular disease. Seventy-one pre-m...

Sporadic nontoxic goiter (SNG) is defined as a benign enlargement of the thyroid gland in a euthyroid subject living in an iodine-sufficient area. Such goiters can be diffuse, uninodular, or multinodular and can vary greatly in size at presentation, growth rate, and symptomatology. The causes of SNG are incompletely understood, but include autoimmune, genetic, and extrinsic factors. SNG is a co...

We report a 55-year-old female who presented with trochanteric fracture of right femur. Examination and investigation revealed a huge retrosternal goiter with compression of great vessels which was asymptomatic for more than two decades. Subsequent investigation confirmed it as a case of toxic multinodular goitre with subclinical hyperthyroidism which is the possible cause of secondary osteopor...

A retrospective, comparative review of 100 consecutive new outpatients presenting with hyperthyroidism in Cardiff, South Wales, and in Toronto, Canada, was performed. The aim was to quantify the causes of hyperthyroidism with particular emphasis on the prevalence of viral thyroiditis and "silent" thyroiditis. The proportional morbidity of Graves' disease (approximately 70%) was similar in the t...

Intrathoracic goiters generally occupy anterior mediastinum, rarely involving the posterior mediastinal space. Reported herein is a 54-year-old female with a giant posterior mediastinal mass that was successfully resected via right posterolateral thoracotomy. The final pathologic diagnosis was giant posterior mediastinal goiter. This patient has done well postoperatively, with no evidence of lo...

Radioiodine (RAI) therapy is a safe and effective treatment for hyperthyroidism and individual doses are frequently administered. Initial thyroid volume (TV) is an important parameter for RAI therapy. Ultrasonography (US) is considered the most reliable method of determining TV. The aim of this study was to evaluate TV by means of US in a cohort of 75 hyperthyroid patients before and after RAI ...
