Abstract
In order to enhance the risk stratification of papillary thyroid carcinoma (PTC) patients, we assessed the presence of the most common mutation in PTC (BRAFV600E) with the expression profiles of long non-coding RNA activated by BRAFV600E (BANCR) and microRNAs, which share complementarity with BANCR (miR-203a-3p and miR-204-3p), and thereafter correlated it with several clinicopathological features of PTC. BRAFV600E was detected by mutant allele-specific PCR amplification. BANCR and miRs levels were determined by quantitative RT-PCR. Bioinformatic analysis was applied to determine the miRs' targets. The expression profile of miR-203a-3p/204-3p in PTC was not affected by BRAFV600E. In the BRAFV600E-positive PTC, high expression of miR-203a-3p correlated with extrathyroidal invasion (Ei), but the patients with both high miR-203a-3p and upregulated BANCR were not at risk of Ei. In the BRAFV600E-negative PTC, low expression of miR-204-3p correlated with Ei, intraglandular dissemination and pT status (p < 0.05), and the mutual presence of low miR-204-3p and upregulated BANCR increased the occurrence of Ei. Bioinformatic analysis predicted complementary binding between miR-203a-3p/204-3p and BANCR. The co-occurrence of tested factors might influence the spreading of PTC. These findings partially describe the complicated network of interactions that may occur during the development of PTC aggressiveness, potentially providing a new approach for high-risk PTC patient selection.

Abstract
INTRODUCTION Non functional parathyroid carcinoma (PC) is one of the rarest malignant neoplasms. Due to the lack of symptoms and laboratory findings, it is mostly diagnosed in late AQ2 stages, when local invasion and dissemination are already present. However, our case is an exception, because it was detected in early stage, with no local invasion present. We present a case of the smallest non-functional PC yet reported and review of the literature. CASE PRESENTATION A 47-year-old woman was admitted to outpatient Clinic where fine-needle aspiration biopsy (FNAB) of bilateral thyroid nodules (slide 1) and central neck mass (slide 2), which was suspected to be an enlarged lymphatic nodule or parathyroid gland was performed. Results came back as Bethesda I-colloid (slide 1), and Bethesda IV (slide 2), stating that it is hard to distinguish thyroid gland oxyphil lesions from parathyroid cells. Total thyroidectomy was performed as well as excision of the left central neck mass, without any involvement of surrounding structures. Pathological examination revealed bilateral thyroid follicular nodular disease, papillary microcarcinoma, and parathyroid carcinoma with vascular and capsular invasion, measuring 10 × 8 × 7 mm. The immunohistochemical profile included positive PTH, Chromogranin A, and negative TTF1. CONCLUSION Non-functional PC is usually diagnosed in advanced stages, already involving adjacent structures; however, this case presents a rare example. It is important not to exclude PC as a differential diagnosis in the absence of elevated Ca and PTH serum levels. Follow-up will be difficult, since there are no prognostic parameters to rely on.

Abstract
Thyroid carcinomas are growing malignancies worldwide. They encompass several diagnostic categories with varying degrees of dedifferentiation. Focal adhesion kinase is involved in cellular communication and locomotion. It is regulated on a posttranscriptional level by miR-7, miR-135a, and miR-138 and on a posttranslational level by autophosphorylation at Y397 (pY397-FAK). We related regulators of FAK with histologic dedifferentiation, clinicopathological factors, and differential diagnosis in the thyroid neoplasia spectrum. We classified 82 cases into 5 groups with increasing aggressiveness: healthy tissue, follicular and classical variants of papillary thyroid carcinoma (PTC), dedifferentiated PTC, and anaplastic carcinoma. MiRs were analyzed by RT-qPCR. Protein expression of pY397-FAK was analyzed by immunohistochemistry (separately in the membrane, cytoplasm, and nuclear compartment) and Western blot. All three miRs were upregulated in healthy tissue compared to malignant, while pY397-FAK was downregulated. MiRs and pY397-FAK were not mutually correlated. MiR-135a-5p was decreasing while membranous and cytoplasmic pY397-FAK increased with dedifferentiation. Neither miR correlated with clinicopathological factors. MiR-135a-5p, miR-138-5p, and membranous and cytoplasmic pY397-FAK discriminated the follicular from the classical variant of PTC. Disturbances of FAK regulation on different levels contribute to neoplastic dedifferentiation. pY397-FAK exerts its oncogenic role in the membrane and cytoplasm. Diagnostically, miRs-135a-5p, miR-138-5p, and membranous and cytoplasmic pY397-FAK differentiated between classical and follicular PTC.

Abstract
PURPOSE The challenge in the diagnosis and treatment of thyroid carcinoma is to correctly classify neoplasias with overlapping features and to identify the high-risk patients among those with a less aggressive form, in order to personalize the treatment of thyroid carcinoma patients accordingly. METHODS MiR-203a-3p, miR-204-3p, and miR-222-3p levels were determined in 99 cases of thyroid neoplasias (77 papillary thyroid carcinomas (PTC) of diverse variants, 12 follicular thyroid adenomas (FTA) and 10 nodular goiters (NG)) along with 99 adjacent non-malignant thyroid tissues using quantitative RT-PCR. The results were evaluated in comparison with the clinicopathological features of the patients and available TCGA data. RESULTS Down-regulated miR-203a-3p indicates the presence of thyroid tumor (PTC or FTA) with high sensitivity (75%) and specificity (73%), while its up-regulation indicates NG. If miR-203a-3p is down-regulated, up-regulated miR-204-3p with high sensitivity (83.3%) and specificity (74.4%) indicates FTA presence, while up-regulated miR-222-3p, with high sensitivity (76.6%) and specificity (75.0%), points to PTC. The expression of miR-204-3p and miR-222-3p depends on the PTC subtype (P < 0.05). While the deregulated expression of tested miRs is associated with a long-range of unfavorable clinicopathological parameters of PTC, only abundant expression of miR-222-3p may be used as an independent predictive factor for the presence of extrathyroid invasion and advanced pTNM stage of PTC (P < 0.05). CONCLUSION Successive evaluation of miR-203a-3p, miR-204-3p, and miR-222-3p expression can help in the differential diagnosis of thyroid neoplasias. A high relative value of miR-222-3p expression is an independent predictive factor for the presence of extrathyroid invasion and advanced pTNM stage of PTC. The panel consisting of miR-203a-3p, miR-204-3p, and miR-222-3p could be used as a diagnostic and prognostic tool for personalizing the treatment of thyroid cancer patients.

Abstract
INTRODUCTION The role of BRAF-activated non-protein coding RNA (BANCR) in papillary thyroid carcinoma (PTC) is controversial, its clinical significance is unclear and no study has correlated the presence of the BRAFV600E mutation in PTC with BANCR expression. METHODS BANCR levels in PTC and matched nonmalignant thyroid epithelial tissues from 85 patients were determined using quantitative RT-PCR. BRAFV600E was detected by mutant allele-specific PCR amplification. The results were correlated with clinicopathological characteristics of the patients. RESULTS The presence of BRAFV600E associates with lower relative BANCR expression (RBE) in PTC (p = 0.008). RBE is down-regulated in BRAFV600E positive PTC, while it is unchanged or up-regulated in BRAFV600E negative PTC compared to the levels in paired nonmalignant tissue (p = 0.001). At the cut-off of 31.3%, sensitivity of fold change of BANCR for the presence of BRAFV600E is 68.0% and specificity is 67.2%. In BRAFV600E positive PTC up-regulated BANCR predicts lymph node metastasis (p = 0.001), while in BRAFV600E negative PTCs high RBE predicts thyroid capsule invasion (p = 0.028). CONCLUSIONS Depending on the presence of BRAFV600E, elevated BANCR levels demonstrated different effects on lymphatic spreading and local PTC invasion. Therefore, BANCR could be a useful prognostic biomarker in risk stratification of PTC patients.

Abstract
Ectopic thyroid tissue is a rare pathological finding bellow the diaphragm and extremely rare finding is ectopic thyroid tissue in the adrenal gland. Thyroid tissue can be located anywhere along the way of embryological migration pathway of thyroglossal duct. In most cases of ectopic thyroid tissue, it is located in the neck. Pathohistologically ectopic thyroid tissue in all cases was formed of follicular cells that expressed TTF-1, Thyroglobulin, PAX8, and cytokeratin 7, and there was lack expression of calretinin. In the literature we found 15 such cases. Women are much more affected than men (14:1), and it usually presents in the fifth decade (mean age 49). In all cases it was composed of normal follicular cells, and C cells were not found. Review of the literature reveals that adrenal ectopic thyroid tissue is almost always cystic, and has distinctive pathologic features. The most important thing is that ectopic thyroid tissue must be distinguished from metastatic deposits from thyroid gland carcinoma.

Abstract
BACKGROUND The etiology of papillary thyroid carcinoma (PTC) is unknown and some literature data support the hypothesis that heavy metals, as endocrine disrupters, could play a major role in the pathogenesis of thyroid cancer. This study aimed to estimate the content of selected toxic and essential trace metals (Mn, Co, Ni, Cu, Zn, As, Se, Cd, Pb, Th, and U), as well as the selected ratio's (Cu/Zn and Cd/Se) in the malignant thyroid tissues according to sex, age, smoking habits, familial history of any thyroid disease, pathohistological (PH) types of PTC, tumor size, the existence of a thyroid capsular invasion, intrathyroid tumor dissemination, retrosternal thyroid growth, and TNM progress of PTC. METHODS The study included 66 patients with PTC (women/men ratio = 46/20, mean age: 54 ± 14 years). A comparative analysis was made by collecting the healthy thyroid tissues (HTTs) of the same patients, making the total number of samples 132. All trace metals were quantified by inductively coupled plasma-mass spectrometry (ICP-MS). RESULTS Metals that significantly separated papillary thyroid tissues (PTTs) from the HTTs were Cd, U and Se (p < 0.05). The obtained negative correlation between Cd and Se in the PTTs could explain extrusion of essential Se caused by increased content of Cd. Only Cd had an influence on the retrosternal thyroid growth, while the essential metals (Mn, Co, and Zn) had an influence on thyroid capsular invasion. CONCLUSION It was found that Cd act as the main endocrine disrupter, which could highlight its role in the etiology of PTC. Considering that the Cd/Se ratio significantly separated two studied groups and had an influence on the retrosternal thyroid growth, its altered content could contribute to the better understanding of the molecular basis for pathophysiological changes in the PTC.

Abstract
Cytological analysis of fine-needle aspiration (FNA) is the first step in evaluation of patients with nodular thyroid disease with the primary goal to exclude thyroid malignancy. Its improvement by combining cytology with molecular markers is still a matter of investigation. In this study, 2 molecular markers were used: caveolin-1 and epidermal growth factor receptor (EGFR), along with the well-established genetic marker BRAF V600E mutation. We set out to determine the expression signatures of EGFR and caveolin-1 in patients with thyroid malignancy as well as to determine their possible association with disease severity. In FNA biopsy samples (n=186), immunocytochemical expression of caveolin-1 and BRAF V600E mutation coincided with malignancy. The patients were sorted according to 3 parameters: final histopathological diagnosis, caveolin-1 expression, and BRAF V600E mutation status before measurement of EGFR mRNA expression. EGFR upregulation was detected in the group of patients with malignant diagnosis, no caveolin-1 expression, and wild-type BRAF. Spearman rank correlation yielded a statistically significant negative correlation of EGFR and caveolin-1. Double immunofluorescence confirmed colocalization and inverse expression of EGFR and caveolin-1. Our data demonstrated that EGFR overexpression is associated with malignancy but not with tumor aggressiveness. Furthermore, high-caveolin-1/low-EGFR cases were associated with an advanced pT status and had a greater degree of neoplastic infiltration than low-caveolin-1/high-EGFR cases. Combining caveolin-1 and BRAF V600E with EGFR might help in recognizing more aggressive thyroid lesions in a pool of relatively indolent tumors in FNA biopsies and thus be useful for early risk stratification of thyroid cancer patients.

Abstract
Difficult tracheal intubation (DI) is more common in thyroid than in other surgical branches due to thyromegaly. Proper preoperative airway evaluation is necessary in order to reduce the potential numerous complications. The study examined the incidence of DI in thyroid surgery and the influence of tracheal dislocation and other risk factors on DI. A prospective study was conducted on 2379 patients who underwent thyroidectomy at the Center for Endocrine Surgery, Clinical Center of Serbia, from 2007 to 2012. Patients were divided into groups with (n = 162) and without DI (n = 2217). Besides tracheal dislocation, another 13 risk factors contained in 13 screening tests and three additional factors of gender, age and diagnosis were defined. The incidence of DI in our study was 6.81%. The presence of tracheal dislocation was statistically significant, but not an independent predictor of DI. The diagnosis, large circumference and small neck length, previous DI, recessive mandible, tooth characteristics and oral anomalies were the most significant and independent predictors of DI. Neck circumference and small neck length had highest sensitivity. Previous DI had highest specificity. Thyromegaly, if causing tracheal dislocation and/or stenosis, represents a significant DI predictor, not individually, but in combination with other factors.
