Patients with intermediate-risk thyroid cancers may undergo treatment with radioactive iodine-131 (I-131). They often undergo a pretreatment diagnostic iodine scan that typically shows areas of physiological uptake in the stomach, bladder, parotid glands as well as thyroid-remnant uptake and sites of metastatic disease. A 48-year-old woman with intermediate-risk papillary thyroid cancer with metastases to lateral compartment lymph nodes was found to have increased retention of iodine in the medial portion of her left orbit on the diagnostic scan.

A new biokinetic model for iodine in dairy cows was developed utilizing data from a 4 × 4 factorial feeding experiment with rumen-cannulated cows that were fed rapeseed cake containing substances known to influence iodine metabolism, and soybean meal without such effects. I was administered both intravenously and intra-ruminally to document metabolism pathways. The new model included compartments such as saliva and thyroid gland, often ignored in other models, and in contrast to previously available biokinetic models, it fitted well to our experimental data.

Disease management of malignant struma ovarii.

Department of Nuclear Medicine, Qiantang Branch of Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, Hangzhou, Zhejiang, China.

Article Synopsis
  • - Malignant struma ovarii (MSO) is a rare type of ovarian goiter that meets criteria for malignant thyroid tumors and can show invasive spread, with serum thyroglobulin (Tg) levels helping to differentiate it from other ovarian cancers.
  • - A case study is presented involving a 54-year-old woman with abdominal pain, diagnosed post-surgery with highly differentiated follicular thyroid carcinoma originating from both ovaries, which had spread to other areas.
  • - After undergoing total thyroidectomy and iodine-131 treatment, her follow-up after one year showed no significant abnormalities, highlighting the need for further discussion on clinical management and monitoring of Tg levels in MSO cases.

Numerical modelling for the distribution of Cs and I in the scheldt basin after a potential nuclear accident.

Institute of Mechanics, Material and Civil Engineering, Université Catholique de Louvain, Louvain-la-Neuve, Belgium; Earth and Life Institute, Université Catholique de Louvain, Louvain-la-Neuve, Belgium. Electronic address:

Using the discontinuous Galerkin method in the SLIM modelling framework, we study the transport in the Scheldt basin and adjacent coastal area of radionuclides possibly emitted by Doel nuclear power plant in the aftermath of an accident. The contamination pathways taken into consideration are direct liquid releases into the water and deposition via the atmosphere. In past nuclear accidents, several radionuclides were released, among which, I and Cs were considered herein.
