Metastasis of clear cell renal cell carcinoma to hyalinizing trabecular tumor of the thyroid: A case report.

Renal cell carcinoma (RCC) is the most common malignancy that metastasizes to the thyroid; however, metastasis of RCC to a primary tumor of the thyroid is rare. The present study reports the case of RCC that had metastasized to the primary thyroid tumor; namely, a hyalinizing trabecular tumor (HTT). Notably, the RCC was resected 2 years prior.

A Benign Lesion of Thyroid Masquerading as a Salivary Gland Malignancy on Cytology.

Introduction: Thyroid lesions are one of the most common diseases observed in clinical practice in the North India. These diseases have distinct cytological morphology and thus FNAC is done frequently. Here we report a case of adenomatoid goitre mimicking adenoid cystic carcinoma (ACC) of salivary gland on cytology.

Endoplasmic reticulum protein TXNDC5 modulates thyroid eye disease TGF-β1-induced myofibroblast transdifferentiation.

Aim: There remain limited therapies to treat thyroid eye disease (TED) orbital fibrosis, highlighting the urgency to develop novel targets. Transforming growth factor-β1 (TGF-β1)-induced myofibroblast transdifferentiation from orbital fibroblasts are important pathogenetic factor of TED. Endoplasmic reticulum (ER) stress may play a role in TED pathogenesis since it has been linked to liver, kidney, heart and lung fibrotic remodelling.

The patient reported transient episodes of weakness over recent weeks, culminating in a severe episode prompting emergency evaluation.

Thyroid-associated ophthalmopathy and ferroptosis: a review of pathological mechanisms and therapeutic strategies.

Thyroid-associated ophthalmopathy (TAO) is an inflammatory orbital disease associated with autoimmune thyroid disorders. Owing to the ambiguous nature of the pathogenesis, contemporary pharmacological treatment strategies predominantly involve the use of glucocorticoids and immunosuppressants. However, the adverse effects associated with these agents in clinical practice necessitate further investigation into the disease's pathogenesis and the identification of novel therapeutic targets and pharmacological interventions.

Graves' Disease and the Risk of Type 2 Diabetes: A Korean Population-Based Study.

Several meta-analyses have found no association between Graves' disease (GD) and an increased risk of incident diabetes; however, the intricate relationship between thyroid dysfunction and diabetes remains underexplored. In this study, we aimed to evaluate the risk of incident type 2 diabetes (T2DM) in a population newly diagnosed with GD, focusing on different treatment methods and treatment duration. This was a retrospective population-based study utilizing data from the Korean National Health Insurance database.

Transcriptomic profiling of thyroid eye disease orbital fat demonstrates differences in adipogenicity and IGF-1R pathway.

Despite recent advances in the treatment of thyroid eye disease thyroid-related eye disease (TED), marked gaps remain in our understanding of the underlying molecular mechanisms, particularly concerning the insulin-like growth factor-1 receptor (IGF-1R) pathway. To dissect the pathophysiology of TED, we used single-nucleus RNA-Seq to analyze orbital fat specimens from both patients with TED and matched individuals acting as controls. The analysis demonstrated a marked increase in the proportion of fibroblasts transitioning to adipogenesis in the orbital fat of patients with TED compared with that in control patients.

Increased incidence of Graves' disease during the COVID-19 pandemic in children and adolescents in the United States.

Introduction: Reports in adults indicate that Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2) infection and vaccination trigger the expression of autoimmune disease such as Graves' disease, but the incidence of new onset Graves' disease and its temporal relationship to the peaks of COVID-19 cases in children are unclear.

Methods: This is a retrospective study of children and adolescents with new-onset Graves' disease diagnosed between September 2017 and August 2022, N=156, mean age of 12.5 ± 4 year (y), with a range of 2.

The ability of virtual noncontrast images to remove intrinsic and external iodine from the thyroid via dual-layer spectral detector computed tomography.

Background: Virtual noncontrast (VNC) images generated by dual-layer spectral computed tomography (DLCT) remove iodine influence from enhanced images to simulate true noncontrast (TNC) images. Previous research has demonstrated the high comparability of abdominal VNC images with TNC images, suggesting their potential as substitutes. Given the thyroid's significant iodine content, this study evaluated the efficacy of VNC images for removing both intrinsic and extrinsic iodine through an analysis of computed tomography (CT) attenuation and iodine density in TNC and enhanced VNC thyroid images.

Outcomes of Total Thyroidectomy in Large Goiters With Retrosternal Extension and Tracheal Compression: A Multivariate Analysis.

Introduction: Large retrosternal goiters often cause tracheal compression and deviation, leading to respiratory symptoms and complicating surgical treatment. Total thyroidectomy is the treatment of choice though it carries a risk of complications due to the altered anatomy and its proximity to vital structures. This study examines the outcomes of total thyroidectomy in patients with retrosternal goiters and assesses the impact of tracheal compression on clinical results.

Comparative effectiveness of various orbital decompression techniques in treating thyroid-associated ophthalmopathy: a systematic review and meta-analysis.

Background: In thyroid-associated ophthalmopathy (TAO), orbital decompression is a critical surgical approach for functional and aesthetic reasons. Meanwhile, the presence of surgical complications, especially the new onset of primary gaze diplopia, also influences postoperative patient satisfaction. This research investigates the effectiveness and potential risks associated with different orbital decompression in patients with TAO.

Methods: Demographic data, white cell count parameters, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), mean platelet volume (MPV), platelet-to-neutrophil ratio (PNR), red cell distribution width (RDW), RDW-to-platelet ratio (RDW/PLT), MPV-to-lymphocyte ratio (MPV/ALC), eosinophil-to-lymphocyte ratio (ELR) and systemic immune-inflammatory index (SII) were evaluated. The European Group on Graves Orbitopathy scale and Clinical Activity Score were used for clinical activity and severity assessment.

Linsitinib inhibits IGF-1-induced cell proliferation and hyaluronic acid secretion by suppressing PI3K/Akt and ERK pathway in orbital fibroblasts from patients with thyroid-associated ophthalmopathy.

Thyroid-associated ophthalmopathy (TAO), an autoimmune disorder of the retrobulbar tissue, is present in up to 50 percent of Graves's hyperthyroidism patients. Insulin-like growth factor 1 receptor (IGF-1R) has received attention as a target for the development of therapeutic agent for TAO. IGF-1R and TSHR (thyroid stimulating hormone receptor) interact with each other to form a physical or functional complex, further promoting the development of TAO.

The signal intensity of the lacrimal gland (LG), extraocular muscle (EOM), ipsilateral temporal muscle (TM), ramus mandibulae, and white matter (WM) on MRI images was measured.

Impact of chronic lymphocytic thyroiditis on the diagnostic and intraoperative management of papillary thyroid cancer.

Background: Chronic lymphocytic thyroiditis is an autoimmune thyroid disorder and the most common cause of hypothyroidism in women. Many studies suggest that chronic lymphocytic thyroiditis contributes to a diagnostic challenge in thyroid nodules and may increase the risk of developing papillary thyroid cancer. This study examines preoperative clinical factors and tumor characteristics associated with papillary thyroid cancer among patients with chronic lymphocytic thyroiditis.
