OBJECTIVE To determine whether clinical and biochemical features of Graves' disease at presentation predict response to medical and radioiodine treatment. METHODS We carried out a retrospective 10-year study of 194 consecutive Saudi subjects with Graves' disease who were treated with antithyroid drugs, radioiodine therapy, or both, between January 1995 and December 2004 at King Khalid Univers...

Radioiodine therapy is the safest, simplest, least expensive and most effective method for treatment of hyperthyroidism. The method employed in this research was a systematic bibliographic review, in which only valid studies or the clinically detailed enough open-labeled studies using validated scales were used. Iodine-131 (I-131) acts by the destructive effect of short-range beta radiation on ...

Salivary gland involvement is one of the radioiodine therapy complications. Salivary gland scintigraphy in quantitative mode can accurately evaluate salivary gland function. Methods: Salivary gland scintigraphy was performed with Tc-99m Pertechnetate, at the time of iodine therapy as a basic study and then 3 weeks and 3 months afterwards. Ejection Fraction (EF) of parotid and submandibula...

Background: Induction of radioadaptive responses in cells pretreated with a low dose radiation before exposure to a high dose is well documented by many investigators. The aim of this study is to determine the frequency of chromosomal aberration in peripheral blood lymphocytes of patients treated by radioiodine (131I) for hyperthyroidism, with or without previous thyroid scan with 99mTc. Materi...

OBJECTIVE Patients with thyroid cancer may require detailed anatomic imaging before 131I therapy. Imaging by contrast-enhanced CT is contraindicated because it may result in saturation of tissues with iodine, decreasing the avidity of thyroid or thyroid cancer cells to subsequent radioiodine for extended intervals. Gadolinium-enhanced MRI offers an alternative to CT for detailed anatomic imagin...

The overall survival rate of non-radioiodine avid differentiated (follicular, papillary, medullary) thyroid carcinoma is significantly lower than for patients with iodine-avid lesions. The purpose of this study was to evaluate toxicity and efficacy (response and survival) of peptide receptor radionuclide therapy (PRRT) in non-radioiodine-avid or radioiodine therapy refractory thyroid cancer pat...

Pemphigus foliaceus (PF) is an autoimmune blistering disease presenting in endemic and sporadic forms. The typical presentation is recurrent shallow erosions in a seborrheic distribution. PF has also been found in association with autoimmune diseases such as autoimmune thyroid disease (e.g. toxic nodular goiter and Hashimoto’s thyroiditis). In some patients, PF appears to be triggered by radioi...

Radioiodine-concentrating activity in thyroid tissues has allowed the use of radioiodine as a diagnostic and therapeutic agent for patients with thyroid disorders such as well-differentiated thyroid cancer. However, some extrathyroidal tissues also take up radioiodine, contributing to unwanted side effects of radioiodine therapy. Now that the molecule that mediates radioiodine uptake, the sodiu...

BACKGROUND Radioiodine treatment of hyperthyroidism in Graves' disease patients may cause or aggravate the course of ophthalmopathy (GO). We evaluated the activity and severity of ophthalmopathy in patients who acquired GO following radioiodine therapy. MATERIAL AND METHODS Between 2003 and 2005, 763 Graves' disease patients (50.9% of the total number of 1,500 patients referred to our Departm...

UNLABELLED Salivary gland dysfunction is one of the common side effects of high-dose radioiodine therapy for thyroid cancer. The purpose of this study was to determine whether an early start of sucking lemon candy decreases salivary gland injury after radioiodine therapy. METHODS The incidence of the side effects of radioiodine therapy on the salivary glands was prospectively and longitudinal...
