A rising incidence of thyroid cancers (TCs) mainly small tumors, observed during recent years, lead to many controversies regarding treatment strategies. TCs represent a distinct molecular background and clinical outcome. Although in most cases TCs are characterized by a good prognosis, there are some aggressive forms, which do not respond to standard treatment. There are still some questions, which have to be resolved to avoid dangerous simplifications in the clinical management. In this article, we focused on the current advantages in preoperative molecular diagnostic tests and histopathological examination including noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP)...

Anaplastic thyroid carcinoma is the rarest but extremely aggressive thyroid cancer subtype. This neoplasia is composed of undifferentiated tumor cells with poor prognosis and resistant to common thyroid cancer therapy. Early stage identification of this cancer for prompt treatment is very vital. Presently, cytological evaluation of fine needle aspiration biopsy (FNAB) which is known as invasive recognition assay, is the standard diagnostic method for the diagnosis of malignant thyroid tumors. Frequent studies have suggested that using the molecular biomarkers of thyroid cancer tissue alongside cytological examination, increase the accuracy of diagnostic tests...

BACKGROUND Muscular symptoms, including stiffness, myalgia, cramps, and fatigue, are present in the majority of the patients with symptomatic hypothyroidism, but rhabdomyolysis, the rapid breakdown of skeletal muscle, is a rare manifestation. In most patients with hypothyroidism who develop rhabdomyolysis, precipitating factors, such as strenuous exercise or use of lipid-lowering drugs, can be identified. CASE REPORT We report a case of a 52-year-old Hispanic woman with a history of hypothyroidism, hypertension, and type 2 diabetes mellitus who presented with fatigue, severe generalized weakness, bilateral leg pain, and recurrent falls...

Autoimmune thyroid disease (AITD) is characterized by immune attacks on the person's own thyroid. Hashimoto's thyroiditis (HT) is a subtype of AITD and is a common cause of hypothyroidism and related symptoms. Regulatory B (Breg) cells can express interleukin 10 (IL-10) and have recently emerged as a critical participant in suppression pathogenic inflammation and promoting peripheral tolerance. The role of Breg cells in HT is not yet clear. In this study, we first examined the IL-10 production by B cells in healthy controls and HT patients, and found that the healthy control B cells demonstrated significantly higher IL-10 expression than HT B cells after CpG stimulation...

Hyperparathyroidism is a common disorder affecting more than hundreds of thousands of people annually. While most commonly secondary to an adenoma, it may also arise from four-gland hyperplasia or malignancy. In the case of primary hyperparathyroidism, the number of glands involved may be unknown prior to surgery. In contrast, the metabolic disorder associated with renal failure induced hyperparathyroidism ensures a hyperplasia picture. Despite the uniform hyperplasia seen in tertiary disease and the preoperative expectation for four-gland exploration, our case demonstrates the continued need for a surgeon's vigilance during dissection to identify all glands and appropriately use intraoperative parathyroid hormone (PTH) testing...

Long-term exposure to dampness microbiota induces multi-organ morbidity. One of the symptoms related to this disorder is non-thyroidal illness syndrome (NTIS). A retrospective study was carried out in nine patients with a history of mold exposure, experiencing chronic fatigue, cognitive disorder, and different kinds of hypothyroid symptoms despite provision of levothyroxine (3,5,3',5'-tetraiodothyronine, LT4) monotherapy. Exposure to volatile organic compounds present in water-damaged buildings including metabolic products of toxigenic fungi and mold-derived inflammatory agents can lead to a deficiency or imbalance of many hormones, such as active T3 hormone...

INTRODUCTION: Graves' orbitopathy is the extra thyroidal manifestation of Graves' disease and the most common cause of exophthalmos. It is also known as thyroid-associated orbitopathy (TAO) as it occasionally occurs in euthyroid or hypothyroid patients with chronic thyroiditis. 5% of patients with Graves' orbitopathy can be euthyroid or hypothyroid as they have low titers of anti-thyrotropin-receptor antibodies, which are difficult to detect in some assays. Orbitopathy has also been seen in a small percentage of patients with Hashimotos thyroiditis...

With the increased pro-inflammatory response in both rheumatoid arthritis and thyroid autoimmune diseases, treatment with biological antirheumatic agents (BAAs) of the former may affect the course of the latter. In hepatitis C and cancer patients, treatment with biological agents substantially increases the risk of developing thyroid autoimmunity. As the use of BAAs in the treatment of rheumatoid arthritis is increasing, this review aimed to investigate if such use affected thyroid status in rheumatoid arthritis patients...

Thyroid hormone (TH) receptors are highly distributed in the hippocampus, which plays a vital role in memory processes. However, how THs are involved in the different stages of memory process is little known. Herein, we used hippocampus dependent contextual fear conditioning to address the effects of hippocampal THs on the different stages of fear memory. First, we found that a single systemic levothyroxine (LT4) administration increased the level of free triiodothyronine (FT3) and free tetraiodothyroxine (FT4) not only in serum but also in hippocampus...
