BACKGROUND: We aimed to examine the diagnostic utility of micronuclei (MN) and nuclear buds (NBs) in aspiration smears of the well-differentiated epithelial lesions of thyroid. METHODS: One hundred five cases composed of 34 follicular nodular disease (FND), 31 Hashimoto's thyroiditis (HT), and 40 papillary thyroid carcinoma (PTC) were compiled retrospectively. May- Grünwald Giemsa (MGG) stained smears of each case were selected to count cells with nuclear protrusions (NPs) per 1000 cells...

OBJECTIVE: The prevalence and clinical relevance of TSH-receptor (TSHR) blocking antibodies (TBAb) in patients with autoimmune thyroid disease (AITD) was investigated. METHODS: Serum TBAb were measured with a reporter gene bioassay using chinese hamster ovary cells. Blocking activity was defined as percentage inhibition of luciferase expression relative to induction with bovine TSH alone (cut-off 40% inhibition). All samples were measured for TSHR stimulatory Ab (TSAb) and TSHR binding inhibiting immunoglobulins (TBII)...

Autoimmune thyroid diseases (AITD) are a group of both B cell- and T cell-mediated organ-specific autoimmune diseases. Graves' disease and Hashimoto thyroiditis are the two main clinical presentations of AITD. Both genetic and environmental factors have important roles in the development of AITD. Epigenetics have been considered to exert key roles in integrating those genetic and environmental factors, and epigenetic modifications caused by environmental factors may drive genetically susceptibility individuals to develop AITD...

BACKGROUND: Ventilatory anaerobic threshold (VAT) is frequently used as a measure of exercise tolerance, with the V-slope method being the standard; however, this needs to be visually determined. Over the years, we have observed that the V-slope itself often appears to shift rightward before the appearance of the VAT (RtShift: rightward shift of V-slope). This phenomenon has long been known to occur during the first 1-2 min of steady-state exercise and disappears thereafter; it is attributed to CO2 storage, presumably in active muscle...

Hashimoto encephalopathy (HE) is believed to be an immune-mediated disorder associated with Hashimoto's thyroiditis. It was suggested that neuropsychiatric symptoms, the presence of antithyroid antibody, and good response to steroids were important for the diagnosis of HE. It has been reported that homovanillic acid (HVA) and 3-methoxy-4-hydroxyphenylglycol (MHPG), which are monoamine metabolites of dopamine and noradrenaline, respectively, are the possible biomarkers of neuropsychiatric diseases. We report a case of Hashimoto encephalopathy, in which we longitudinally measured the plasma levels of monoamine metabolites...

The aim of this study was first to investigate the oxidative proteins modifications in the plasma of both autoimmune thyroid diseases (AITD), Graves' disease (GD) and Hashimoto Thyroiditis (HT). Then, the impact of these oxidative modifications on immune response was evaluated by measuring the reactivity of patients' autoantibodies against malondialdéhyde (MDA) and Hydrogen peroxide (H2O2) modified thyroid antigens (T.Ag) in comparison to native ones. Carbonyl and thiol groups, and MDA-protein adducts were first assessed among 74 AITD patients and 65 healthy controls...

BACKGROUND: Mesenchymal stem cells (MSCs) are multipotent stem or stromal cells found in multiple tissues. Intravenous MSC injections have been used to treat various diseases with an inflammatory component in animals and humans. Inflammation is emerging as a key component of pathophysiology of intracranial aneurysms. Modulation of inflammation by MSCs may affect sustained inflammatory processes that lead to aneurysmal rupture. OBJECTIVE: To assess the effect of MSCs on the development of aneurysm rupture using a mouse model...

To investigate in a long-term study, the development of new extra-glandular manifestations (EGM) or associated auto-immune diseases (AID) from 1 year after establishing the diagnosis of primary Sjögren's syndrome (pSS). The primary goal was to examine the frequency and type of these manifestations and to find out which demographic, clinical and serological profile was most at risk. All outpatients diagnosed with primary Sjögren's syndrome were included in a retrospective study, with at least one check-up per year, from June 1991 until August 2015...

Tumor resection with cardiopulmonary bypass (CPB) remains controversial in the field of oncology. Here, we present a 57-year-old male patient with locally advanced squamous cell carcinoma. The tumor was located in the left hilum and invaded the left atrium. Complete resection, left pneumonectomy combined with partial left atrium resection, was achieved using CPB. We evaluated the circulating tumor cell (CTC) counts, as a surrogate for micrometastasis, in peripheral blood and the CPB circuit. Both CTC counts were 0, which could indicate local disease without micrometastasis...

Chronic spontaneous urticaria (CSU) patients are widely held to often have other autoimmune disorders, including autoimmune thyroid disease. Here, we systematically evaluated the literature on the prevalence of thyroid autoimmunity in CSU and vice versa. There is a strong link between CSU and elevated levels of IgG anti-thyroid autoantibodies (AAbs), with most of a large number of studies reporting rates of ≥10%. Levels of IgG against thyroid peroxidase (TPO) are more often elevated in CSU than those of other IgG anti-thyroid AAbs (strong evidence)...

The purpose of the study was to construct an efficient classifier that, along with a given reduced set of discriminant features, could be used as a part of the computer system in automatic identification and classification of ultrasound images of the thyroid gland, which is aimed to detect cases affected by Hashimoto's thyroiditis. A total of 10 supervised learning techniques and a majority vote for the combined classifier were used. Two models were proposed as a result of the classifier's construction. The first one is based on the K-nearest neighbours method (for K = 7)...

The non-inferiority of oral ibandronate 100 mg to intravenous (i.v.) ibandronate 1 mg in increasing lumbar spine (LS) bone mineral density (BMD) after 12 months of treatment was demonstrated in the randomized, phase III MOVEST study. We conducted subgroup analyses in the per-protocol set of the study (n = 183 oral ibandronate; n = 189 i.v. ibandronate). In patients with LS BMD T score ≥ -3.0 or < -3.0 at screening, LS BMD gains from baseline were 4.42 and 5.79%, respectively, with oral ibandronate, and 4...

PURPOSE: Hashimoto's thyroiditis (HT) as a chronic autoimmune disease of the thyroid gland is the most common cause of hypothyroidism. Since HT and hypothyroidism are closely related, the main aim of this study was to explore the association of established hypothyroidism single-nucleotide polymorphisms (SNPs) with HT. METHODS: The case-control dataset included 200 HT cases and 304 controls. Diagnosis of HT cases was based on clinical examination, measurement of thyroid antibodies (TgAb, TPOAb), hormones (TSH and FT4) and ultrasound examination...

PURPOSE: To evaluate the diagnostic accuracy of routine calcitonin measurement in patients with nodular thyroid disease. METHODS: Consecutive patients with nodular thyroid disease (n = 640) were studied. Serum calcitonin levels were measured under basal conditions, and when basal values were between 10-100 pg/mL, testing was repeated after pentagastrin (PG) stimulation. Patients with previously diagnosed or familial medullary thyroid cancer (MTC) were excluded. Patients were operated on when basal or stimulated calcitonin >100 pg/mL or when other surgical indications were present...

Abdominal aortic aneurysm (AAA) is a vascular disease that results in the gradual dilation of the abdominal aorta and has a high rupture-related mortality rate. However, the mechanism of AAA rupture remains unknown. In our previous study, we established a novel AAA animal model (hypoperfusion-induced AAA rat model) with spontaneous AAA rupture. Using the hypoperfusion-induced AAA rat model, we demonstrated that the abnormal appearance of adipocytes in the vascular wall is associated with AAA rupture. However, pathological analysis of the rupture area has not been performed because it is particularly difficult to identify the rupture point...
