We performed a retrospective review of (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) examination to determine the prevalence of thyroid FDG-PET incidentaloma in a patient group evaluated for metastasis of cancer and in a group of healthy subjects who underwent voluntary cancer screening. We also evaluated the risk of malignancy in focal(More)
BACKGROUND The BRAFV600E mutation is highly specific to papillary thyroid carcinoma. A test for this mutation may increase the diagnostic accuracy of fine-needle aspiration cytology (FNAC), especially in a BRAFV600E mutation-prevalent population. METHODS This prospective study enrolled 1074 patients with thyroid nodules who underwent both FNAC and(More)
The indications for and extent of routine lymph node dissection in patients with papillary thyroid carcinoma (PTC) are unclear. The aim of this study was to investigate the association between the extent of central lymph node dissection (CLND) and the therapeutic effects and potential risks in patients with a small PTC. A total of 103 patients with a PTC <2(More)
BACKGROUND Between 10 and 30% of the fine needle aspiration biopsies (FNABs) of thyroid nodules are diagnosed as 'indeterminate'. A molecular diagnostic method is needed to reduce unnecessary surgery in this group. In Korea, most thyroid cancer is the classic papillary type and the BRAF(V600E) mutation is highly prevalent. AIM To evaluate the role of(More)
Although papillary thyroid carcinoma (PTC) often presents as multifocal or bilateral tumors, but whether multifocality or bilaterality is associated with disease recurrence/persistence is controversial. We evaluated the association between multifocality and bilaterality of PTC and disease recurrence/persistence. We also analyzed the location and number of(More)
OBJECTIVE Epidemiological studies have demonstrated that excess weight increases the risk of thyroid cancer. However, the associations between excess weight and prognostic factors for thyroid cancer are uncertain. We evaluated the relationships between body mass index (BMI) and clinico-pathological features and outcomes of papillary thyroid cancer (PTC). (More)
We tested the ability of healthy elderly persons to use anticipatory synergy adjustments (ASAs) prior to a self-triggered perturbation of one of the fingers during a multifinger force production task. An index of a force-stabilizing synergy was computed reflecting covariation of commands to fingers. The subjects produced constant force by pressing with the(More)
CONTEXT Detection of the BRAF V600E mutation in fine-needle aspiration cytology (FNAC) specimens may increase the value of FNAC. OBJECTIVE The objectives of the study was to compare the diagnostic performance of BRAF assays that differ in sensitivity and to examine the associations between the BRAF V600E mutation status and the clinicopathological(More)
Tumor localization is difficult in patients with medullary thyroid carcinoma (MTC) that have persistent hypercalcitoninemia after thyroidectomy. In this study, the (11)C-methionine positron emission tomography/computed tomography (PET/CT) was compared with the (18)F-FDG PET/CT for diagnostic sensitivity in detecting residual or metastatic disease.(More)
AIMS In this study, we investigated whether pre-conditioning (PC) by electrical stimulation (EleS) induces cytoprotective effect on cardiac stem cells (CSCs) and determined its underlying molecular mechanisms. METHODS AND RESULTS Sca-1(+) CSCs were isolated from male C57BL6 mice (12 weeks) hearts. PC of CSCs with EleS ((EleS)CSCs) was carried out for 3 h(More)
