Background: Our hospital is located 40 km from the nuclear power plants(Tokyo Electric Dai-ichi; NPP) exploded in northern east Japan disaster (2010.3). After the explosion, yearly radiation dose reached to 1-10 mSV in our city and 10-50 mSV in most poluted areas (next to our city). In former ESE congress, we reported cytological analysis of nodular goiter (NOD). In the present study, patients’ thyroid autoimmunity was analyzed whether there is any difference between pre-...

Background: Abnormal thyroid autoimmunity is often experienced in thyroid clinic. Some of them are associated with hyperthyroidism (HY) or chronic thyoiditis (Hashimoto, HA). The abnormality, however, is observed not only in HY or HA, but nodular goiter (NOD), and seems to be associated with various factors; age, visiting periods, residence, ABO blood type or others. We analyzed long-term (more than 16 years) data of patients who live in northeast Japan, if there is any charac...

BackgroundAn increase of pediatric thyroid cancer has been reported in Fukushima area. While there is no adult survey to date except NPP workers. Our institute is located 40 km from the NPP and has been playing a major medical role in this area (population 340, 000). We analyzed patients with NOD whether there is any difference in cytological findings between pre- and post-NPP accident. Patients and methods:1, 065 new patients (2005–2020) with NOD w...

Introduction: Surgery for benign nodular goiter (NOD) is currently limited to cancer or cosmetic deformities. Most patients are, in principle, followed up for years or decades. The long-term outcome, however, is not always clear.Patients and methods: NOD was diagnosed as benign in 1,825 patients (1990–2015). 102 patients (5%) were treated by surgery. 95% returned to home doctors (69%) or continued to visit our clinic (518 patients, 31%). Follow-up e...

Background: Nodular goiter (NOD) is one of the most common disease (69% in our thyroid clinic). Although the nodular growth is generally slow, it may be influenced by thyroid hormones, autoimmunity or other factors. The analysis may contribute to predict the outcomes.Patients and methods: 2,213 Japanese patients (2007–2018; Fukushima coast area) with NOD were enrolled in this study. Mean observation period was 6.4 years with 7 visits (1–50). Th...

Nodular goiter (ND) is increasingly found by image analysis. The long-term course of ND, however, is not necessarily clear and may differ in locality. The present study analyzed the changes of ND in Japanese, taking iodine-rich foods, during follow-up periods.Patients and methods: Patients (n=4,229) were followed up to 28 years (3.4±5.8 years). Volume of nodules (VOL) by ultrasonography (US) and laboratory data, including thyroid hormones (...
