The efficacy of radioiodine treatment of feline hyperthyroidism is well established; however, limited information is known about owners' perceptions or experiences of radioiodine. This study aimed to examine factors that influence owner treatment choices and their opinions following radioiodine. Surveys were sent to owners of cats referred for radioiodine treatment between 2002 and 2011 (radioi...

Patients with advanced DTC who are refractory to I treatment have a life expectancy of 36 years and represent a group for whom there is a clear unmet medical need (1). Radioiodine refractory thyroid cancer is not common, with an estimated incidence of four cases per million population year (5% of patients with clinical thyroid cancer, 250 patients per year in France) (2,3). It occurs more frequ...

BACKGROUND The purpose of using a whole-body scanning after the radioactive I-131 treatment is to screen functional residual or metastatic thyroid tissues. In whole-body scanning of some patients, false positive radioiodine I-131 uptakes may be seen in physiological uptake regions or atypical localizations. CASE REPORT A 54 year-old woman underwent total thyroidectomy for papillary thyroid ca...

Hellenic Journal of Nuclear Medicine January April 2011 www.nuclmed.gr 2 Figures 2 and 3. 131I-SPET study (Fig. 2) further clarified these foci in both kidneys. 18F-FDG-PET scan (Fig. 3) done on a separate day revealed abnormal foci of 18F-FDG uptake in the lower poles of both kidneys, corresponding to the foci seen on post treatment 131I-SPET. In the 18F-FDG-PET image, the foci can be well vis...

Salivary dysfunction and sialadenitis are well known complications of radioiodine treatment for thyroid cancer. The parotid gland is more frequently affected and the salivary gland injury is dose related. The symptoms may develop shortly after therapeutic Iodine 131(I-131) administration or months later and progress with time. The development of unilateral parotiditis following a low dose, diag...

Subacute thyroiditis is generally felt to have a viral etiology, and the diagnosis is usually obvious when the patient presents with a diffusely enlarged and very tender thyroid gland associated with elevated free T4 levels, elevated sedimentation rate, low radioiodine uptake and/or nonvisualization on scan and often some systemic symptoms. Subacute thyroiditis can be unilateral or focal (1,2)....

Despite 70 years of experience treating thyrotoxic patients with radioiodine not all patients are successfully treated by a single dose. Multiple factors predicting radioiodine efficacy have been reported. The aim of this study was to assess whether ethnicity was associated with radioiodine response. A retrospective review was performed of patients who received radioiodine therapy for thyrotoxi...

Hypercalcaemia is a recognised complication of hypothyroidism. We describe three patients who developed hypercalcaemia after thyroidectomy when thyroid supplements were discontinued. They were treated with thyroxine, dihydrotachysterol, and calcium after operation, and in all three cases serum calcium concentrations remained constant during combined treatment. Thyroxine treatment was discontinu...
