Context: Although 60% of papillary thyroid carcinomas are BRAFV600E mutant (PTCV600E), the higher aggressiveness of these cancers is still debated. Objective: In PTCV600E we aimed to further characterize the extent of the stroma and its activation, the 3D tumor-stroma interface, and the proliferation rates of tumor and stromal fibroblasts. Design: We analyzed exomes, trancriptomes and images of 364 PTC from The Cancer Genome Atlas (TCGA), including 211 PTCV600E; stained 22 independent PTC for BRAFV600E and Ki67; sequenced the exomes and stained BRAFV600E in 5 primary tumor blocks and 4 nodal metastases from one PTCV600E patient; and reconstructed the 3D volumes of one tumor and one metastatic blocks at histological resolution...

Probe-based confocal laser endomicroscopy has a high potential to be a promising tool that can provide intraoperative high-resolution in vivo morphological imaging at cellular and subcellular levels for thyroidectomy, and allow real-time assessment of tumor margins. However, the typical images acquired with this technique cover a very small area limited by the field of view of the probe, accompanied by tissue deformation and inconsistent probe-tissue contact when operated manually. In this paper, a novel compact robotic device for large area scanning has been developed...

INTRODUCTION: Hyperthyroidism is rarely associated with malignancy, but it cannot rule out thyroid cancer. Although there is published data describing this coexistence, thyroid carcinomas inside autonomously functioning nodules are uncommon. PRESENTATION OF CASE: A 49-year-old woman presented with a cervical mass, unexplained weight loss and anxiousness, sweating and insomnia. On physical examination, she had a palpable left thyroid nodule. Thyroid function tests showed suppressed TSH (<0,1 uUI/mL), thyroxine 1,44 ng/dL (normal range 0,70-1,48) and triiodothyronine 4,33 pg/mL (normal range 1,71-3,71)...

OBJECTIVES/HYPOTHESIS: Young professional singers can easily reach very high pitches. In contrast, older singers often complain that they have to exert substantially more laryngopharyngeal force to reach the same high pitch compared with their earlier years. Various factors such as the property changes of the mucosa and ossification that impact the singing apparatus were suggested as explanations in the literature. The aim of this study was to analyze thyroid deformation-and thereby stiffness indirectly-during singing as a potential reason for this phenomenon...

OBJECTIVE: After radioiodine therapy of differentiated thyroid cancer (DTC) patients, whole body scintigraphy (WBS) is standard procedure before releasing the patient from the hospital. A common problem is the precise localization of regions where the iod-avide tissue is located. Sometimes is practically impossible to perform precise topographic localization of such regions. METHOD: In order to face this problem, we have developed a low-cost Vision-Fusion system for web-camera image acquisition simultaneously with routine scintigraphic whole body acquisition including the algorithm for fusion of images given from both cameras...

The pathogenesis of Graves' orbitopathy (GO) is not completely understood. Coexistent hyperfunction of the thyroid gland is frequent; however, GO may also coexist with hypo- or euthyrodism. The course of GO is largely independent of thyroid function, although elevated serum TSH is known to negatively interfere with GO course. GO is severe in 10 % of the cases; sight threatening complications may also develop. A successful therapy of GO requires the assesment of both the severity and activity of orbital inflammation...

Background: Ultrasonography (US) is being recognized as a traditional way of the diagnosis of various thyroid disorders, and this will help in detecting the thyroid tumors in early stage. Thyroid nodules are common and usually benign; steps to diagnose malignancy should include a careful clinical evaluation, laboratory tests, a thyroid US exam and a fine-needle aspiration (FNA) biopsy. Methods: A total of 173 registered cases were used for analysis in this study...

Amyloid goiter (AG) is defined as the diffuse enlargement of the thyroid gland resulting from extensive amyloid deposition. Imaging findings in AG may vary depending on the amount of amyloid and fat deposition. A few case reports of AG with clinically subacute thyroiditis (SAT)-like syndrome have been published. However, there have been no reports on AG mimicking SAT with clinical and imaging findings. Herein, we present a case of AG mimicking SAT with a detailed report of the clinical and imaging findings.

Amino acids derivatives are well established molecular probes for diagnosis of a variety of cancer using positron emission tomography (PET). Recently, boramino acid (BAAs) was found as a prospective molecular platform for developing PET tracer. The objective of this study was to develop a 18F-labeled alanine derivative through displacing its carboxylate by trifluoroborate as a selective ASCT2 marker for cancer imaging. 18F-Ala-BF3 was firstly evaluated in healthy FVB/N mice in vivo, exhibiting rapid renal clearance with almost negligible uptake in stomach (1...

The Delphian nodes (DNs) are frequently involved in cancers of the head and neck, including laryngeal and thyroid malignancies. Positivity in the DN has been considered a predictor of recurrence as well as an overall aggressive tumor biology. However, little has been written regarding the consequences of recurrence at the site of the DN. We present two case reports regarding recurrence in the DN and the unique challenges associated with DN metastases. In addition, we discuss our surgical approach to disease at the prelaryngeal space, including workup, imaging, and resection...

Simultaneous existence of parathyroid adenoma and thyroid nonmedullary carcinoma is rarely observed. A 52-year-old female was diagnosed approximately 4 years ago with primary hyperparathyroidism (PHPT) on the basis of hypercalcemia and elevated serum parathyroid hormone (PTH) level. Clinically, PHPT diagnosed patient was examined with Tc-99m MIBI scintigraphy to investigate parathyroid adenoma. Early Tc-99m MIBI images showed focal focused enhanced activity retention on both thyroid left lobe upper pole and thyroid lower pole inferior neighborhood...
