AIMS To determine the long term visual outcome of patients who were eligible for randomisation to enucleation versus brachytherapy in a US collaborative ocular melanoma study (COMS) but were treated with either helium ion or 125I radioactive plaque therapy. METHOD A retrospective analysis was performed of 426 ciliochoroidal melanomas that met COMS inclusion criteria for randomisation to enucl...

Patients entering hospitals in the USA are reported to have about one chance in three of having a radioactive tracer play a role in the diagnosis of their medical problem. , One important diagnostic technique is radionuclide imaging — the use of radioactive isotopes to obtain images of body organs and processes. The IAEA, from its very beginning, has paid close attention to this particular fiel...

Endogenously radioiodinated thyroglobulin (tg) and thyroxine (T4), in the circulation following, therapeutic doses of radioiodine were studied in five patients with differentiated thyroid carcinoma. Radioactive serum was fractionated on a Sephadex G-200 and the various radioactive peaks thus obtained were analyzed for their biochemical and immunologic characteristics using precipitation with tr...

PURPOSE To report the finding of nasolacrimal drainage system obstruction associated with radio iodine therapy and to review clinical data and the surgical treatment outcome of this rare complication. METHODS We retrospectively analyzed ophthalmological data of patients with history of thyroid carcinoma that underwent radioactive iodine I-131 therapy and were referred to lacrimal surgery. R...

OBJECTIVE To investigate the long term effect of radioactive iodine on thyroid function and size in patients with non-toxic multinodular goitre. DESIGN Consecutive patients with multinodular non-toxic goitre selected for radioactive iodine treatment and followed for a minimum of 12 months (median 48 months) after an intended dose of 3.7 MBq/g thyroid tissue corrected to a 100% uptake of iodin...

background: radioactive iodine is widely used for the treatment of various thyroid disorders. safety issues are often a source of worry and anxiety for the patients, their families and comforters. the patients are advised to restrict their social and work related activities. the work presented in this study describes the results of a structured survey conducted on patients visiting our hospital...

Hypothyroidism is one of the most common endocrine diseases. More than 99% all cases hypothyroidism in adults are due to primary hypothyroidism. Most often, develops because chronic autoimmune thyroiditis, as well after medical manipulations (iatrogenic hypothyroidism) — postoperative or a result therapy with radioactive iodine. The article presents draft clinical guidelines for diagnosis and t...

he topic of radioactive waste generates debate, both publicly and scientifically. Like chemical and other hazardous waste, radioactive waste needs to be dealt with to ensure its safety and its security. Proper management and disposal of most forms of radioactive waste is technically straightforward. A robust safety regime has been developed internationally for managing and disposing of radioact...

conclusions the results demonstrated that the mortality rate was higher in cf patients with a positive family history, a consanguineous marriage, and residence in a rural area. therefore, demographic factors play an important role in the outcome of cystic fibrosis. unfortunately, these parameters, which can be managed easily and with low cost, have been overlooked. patients and methods this was...

introduction: hyperthyroidism is a relatively common disorder caused by different etiologies. graves’ disease, and toxic-nodular goiter (plummer’s disease) are among the most common causes. treatment with radioiodine is considered to be the treatment of choice in many of the patients. higher biological half-life of ¹³¹i in hyperthyroid patients as compared with patients with differentiated thyr...
