Authors: Memon A, Rogers I, Paudyal P, Sundin J Abstract We revised and added text to the abstract according to the 5 points/suggestions raised by Reviewer 1. Because of these additions, the abstract now contains 409 words, and therefore does not fit in this box completely due to 350 words limit. It is given in the Final text - R2 version document.

In this study, we reviewed major human studies on the health risks of radiation exposure and showed that sex-related factors may potentially influence the long-term response to radiation exposure. Available data suggest that long-term radiosensitivity in women is higher than that in men who receive a comparable dose of radiation. The report on the biological effects of ionizing radiation (BEIR VII) published in 2006 by the National Academy of Sciences, United States emphasized that women may be at significantly greater risk of suffering and dying from radiation-induced cancer than men exposed to the same dose of radiation....

1129Background: Astatine (At) is increasingly focusing attention in theragnostics because of its similar chemical properties to iodine and of its alpha particles which have shorter range in tissue compared with beta particles. However, previous studies on the biodistribution of At-211 in rats have shown that the uptake of At-211 in thyroid gland was not as high as expected compared to extrathyroidal organs like stomach. The purpose of this study was to evaluate the uptake of At-211 solution treated with reducing agent in the thyroid gland. [Methods] Two groups of male Wistar rats (total n=6, body weight=295.2 ± 16.2...

Follow me on Twitter @drClaire Children often complain of being tired. Usually it’s for simple reasons — because it’s the end of a busy day, or because they stayed up late the night before, or because they are trying to get out of doing something they don’t want to do. When kids are sick they are usually tired, and need more rest to get better. But when a child complains all the time, and fatigue starts to get in the way of things they usually enjoy, it could be a sign of a problem. Here are some possible reasons for chronic fatigue in children: Sleep problems. This makes sense, obviously, since if...

CONCLUSIONS: While "radiosensitivity" was historically related to RI adverse tissue events attributable to cell death, the first efforts to quantify the RI risk specific to each organ/tissue revealed some different semantic fields that are not necessarily compatible together (e.g. adverse tissue events for skin, cataracts for eyes, RI cancer for breast or thyroid). To avoid such confusion, we propose to keep the historical definition of "radiosensitivity" to any clinical and cellular consequences of radiation attributable to cell death and to introduce the term "radiosusceptibility" to describ...

In conclusion, excess nitrate intake seems to be an independent risk factor for DTC. Additionally, we hypothesize from our data that high nitrate levels modulate the carcinogenic effect of radiation on the thyroid. Cohort studies, case-control studies, or both, are needed to quantify the effects of nitrates on DTC risk in the presence or absence of radiation exposure, e.g., that associated with diagnostic or therapeutic health care interventions.Eur Thyroid J

CONCLUSIONS: The results of this meta-analysis indicates that diagnostic radiation exposure is associated with an increased thyroid cancer risk. Therefore, to the extent that it will not compromise the information being sought, radiation exposure to the thyroid should be minimized during diagnostic examinations.

We present four cases of Saudi patients with Paget disease with variable presentations. The first case, a 63-year-old woman with a history of papillary thyroid cancer, presented with bone, shoulder and chest wall pain and foci of uptake in the ribs and skull that were thought to be metastases, indicating the possibility of diagnostic difficulty in a patient with history of malignancy. Bone biopsy confirmed the diagnosis of Paget disease. The second case was a 47-year-old asymptomatic woman with an elevated alkaline phosphatase of 427 U/L, a common presentation but at an unusual age. Plain x-rays and bone scan confirmed the...
