Although several reports have defined normal thyroid volume depending on either age or body surface, there are no sequential reference values on childhood thyroid volume evaluated by using ultrasonography and epidemiological analysis in Japan. The aim of the present study was to establish updated reference values for thyroid volume by ultrasound examination and epidemiological analysis in 0-19 year-old Japanese children. It is based on a cross-sectional study conducted from October 9, 2011 to March 31, 2012. The subjects were 38,063 children who were examined by ultrasonography as the initial preliminary survey of the Fukushima Health Management Survey in October 9, 2011 to March 31, 2012. The width, thickness, and height of each lobe were measured and the volume of each lobe was calculated by the mean of the elliptical shape volume formula. The values of thyroid volume at the 2.5 and 97.5 percentiles of age and body surface area for each gender group were obtained from 0-19 year-old children. Positive correlation was observed between thyroid volume and either age or body surface. The right lobe was significantly larger than the left lobe. The thyroid volume in females was larger than that in males after adjusting body surface area. The reference values of childhood thyroid for each age or body surface area were obtained by this extensive survey using ultrasound. These reference values may be used to define the normal size of thyroid gland by echosonography in Japanese children, although thyroid volume may be affected by dimorphic factors such as sex hormones.

After the Fukushima nuclear power plant accident on March 11, 2011, the public of Japan became particularly concerned about the possibility of an increased risk of childhood thyroid cancer, similar to what was observed after the Chernobyl’s accident. Due to serious public health perception, there was an urgency to evaluate the baseline levels of childhood thyroid status in Fukushima prefecture. Therefore we have commenced a thyroid ultrasound examination (TUE) survey of the approximately 360,000 pediatric inhabitants (0 to 18 years of age) who lived in Fukushima at the time of the accident in October 2011. The subjects were divided into three categories according to the standardized diagnostic criteria of ultrasound findings. Category A contained the subjects whose TUE findings were intact or benign. Category B were recommended a confirmatory TUE. Category C was recommended an immediate confirmatory TUE. Results: The survey of 40,302 subjects in the first year was completed in March, 2013. There were 40,097 (99.5%), 205 (0.50%) and 0 subjects in categories A, B and C, respectively. Of the 82 category B subjects who underwent FNAC, 12 were diagnosed with a malignant tumor or were suspected to have malignancy. The 12 subjects received thyroid surgery and 11 thyroid cancers and one benign nodule were confirmed histologically after surgery. This is the first large-scaled TUE survey to employ sophisticated ultrasound screening and aim to evaluate the baseline frequency of childhood thyroid nodules and cysts. The results will become the golden standard of future comparative TUE in Fukushima, Japan.

Background and Aims: Several investigators have reported the significance of circulating galectin-3 in thyroid cancer patients. However, the precise meaning of circulating galectin-3 remains unclear. The aim of this study was to investigate the relationships between serum galectin-3 levels and angiogenetic factors, and nutritional and inflammatory indicators in patients with thyroid cancer. Materials and Methods: Sixty-one patients with thyroid tumors were enrolled, comprising 47 pre-treatment thyroid cancer patients and 14 patients with benign thyroid diseases. Galectin-3, interleukin (IL)-6, vascular endothelial growth factor, granulocyte colony-stimulating factor (G-CSF), soluble form of intercellular adhesion molecule-1 (sICAM-1), retinol binding protein, prealbumin, albumin, and transferrin were measured. C-reactive protein (CRP), neutrophil count, lymphocyte count, and neutrophil/lymphocyte ratio (NLR) were also investigated. Results: The amounts of circulating galectin-3 in benign disease and thyroid cancer were significantly higher than those of healthy volunteers (P < 0.001). Analysis of galectin-3 performance in distinguishing malignant disease from benign disease using a receiver operating characteristic curve revealed that the area under the curve was 0.555. There were statistically significant correlations between the circulating amount of galectin-3 and IL6, G-CSF, and sICAM-1. Serum galectin-3 showed statistically significant correlations with albumin, prealbumin, and transferrin. Circulating galectin-3 exhibited strong correlations with CRP, neutrophil count, lymphocyte count, and NLR. Conclusions: Galectin-3 may be one of the key factors in the regulation of angiogenesis, inflammation, and nutrition.
