The spleen selectively removes cells with intracellular inclusions, for example, detached nuclear fragments in circulating erythrocytes, called Howell-Jolly Bodies (HJBs). With absent or deficient splenic function HJBs appear in the peripheral blood and can be used as a simple and non-invasive risk-indicator for fulminant potentially life-threatening infection after spleenectomy. However, it is still under debate whether counting of the rare HJBs is a reliable measure of splenic function. Investigating HJBs in premature erythrocytes from patients during radioiodine therapy gives about 10 thousand times higher HJB counts than in blood smears...

OBJECTIVES: Follow-up of patients with low-risk differentiated thyroid cancer treated with total thyroidectomy and radioiodine requires neck sonography and thyroglobulin (Tg). The need to stimulate Tg is controversial. The goal of this study was to compare the diagnostic performances of sonography plus suppressed or stimulated Tg in low-risk thyroid cancer. METHODS: After total thyroidectomy and radioiodine, patients with low-risk thyroid cancer were retrospectively identified as having structural or biochemical persistence/recurrence...

OBJECTIVES: In thyroid cancer treatment, the thyroid-stimulating hormone (TSH) must be elevated before radioiodine ablation, either by exogenous (with recombinant human thyrotropin [rhTSH]) or endogenous stimulation by thyroid hormone withdrawal (THW). The use of rhTSH avoids hypothyroidism and favours the subsequent elimination of radioiodine, but involves the cost of the product. For this reason, a cost-effectiveness analysis was performed, taking into account all costs involved and the benefits associated with the use of this therapy...

PURPOSE: Aberrant expression of human sodium iodide symporter (NIS) in breast cancer (BC) is well documented but the transcription factors (TF) regulating its aberrant expression is poorly known. We identify the presence of three p53 binding sites on the human NIS promoter sequence by conducting genome-wide TF analysis, and further investigate their regulatory role. METHODS: The differences in transcription and translation were measured by real-time PCR, luciferase reporter assay, site-directed mutagenesis, in vivo optical imaging, and chromatin immunoprecipitation...

This study set out to investigate chromosomal damage in peripheral blood lymphocytes of thyroid cancer patients receiving (131)I for thyroid remnant ablation or treatment of metastatic disease. The observed chromosomal damage was further converted to the estimates of whole-body dose to project the adverse side effects. Chromosomal aberration analysis was performed in 24 patients treated for the first time or after multiple courses. Blood samples were collected before treatment and 3 or 4 days after administration of 2-4 GBq of (131)I...

Radioiodine uptake in the thyroid tissue, metastasis of differentiated thyroid cancer (DTC), and in other tissues, depends on the expression of sodium-iodide symporter (NIS). Vascular permeability, effusions, inflammation, and other mechanisms may also play a role in the accumulation of radioactive iodine. A 63-year-old woman underwent radioiodine therapy, as well as a post-therapy whole-body scan,as she was suspected of having lung metastasis from thyroid carcinoma. The scan not only showed uptake at the lung metastasis but also a faint diffuse bilateral uptake in the posterior thorax...

Gliomas, the most prevalent type of brain tumor in adults, are associated with high rates of morbidity and mortality. Recent studies on (131)I labeled scorpion toxins suggest they can be developed as tumor-specific agents for glioma diagnosis and treatment. This study investigated the potential of (131)I labeled Buthus martensii Karsch chlorotoxin ((131)I-BmK CT) as a new approach for targeted imaging and therapy of glioma. The results showed that (131)I can be successfully linked to BmK CT with satisfactory radiochemical purity and stability and that (131)I-BmK CT markedly inhibited glioma cell growth in a dose and time dependent manner, with significant accumulation in glioma cells in vitro...

Radioiodine can be released from nuclear accidents and cause internal contamination of the thyroid gland of members of the public. In thyroid measurements of the general public, the counting efficiency is very important to accurately determine thyroid activity. Here, we estimated the counting efficiencies of a portable NaI detector using Monte Carlo simulations. Two different types of neck phantoms and a 7.62×7.62 cm2 NaI detector were modeled and the counting efficiencies were calculated depending on the thyroid size and distance from the neck phantom to the detector...
