Diagnostic Significance of CTCs in Patients With Thyroid Nodules (Circulating Tumor Cells)

Thyroid NoduleDiagnoses Disease

Thyroid nodule patients with suggestion of fine needle aspiration biopsy (FNAB) offered by ultrasound are enrolled in the study. CTCs tested by Optimizing method and FNAB will be performed simultaneously. This is a double blind trial which pathologists and inspectors of CTCs don't know the result of each other. Surgical pathology and diagnostic results of FNAB is the primary endpoint and comparison will be made to see if CTCs combined with ultrasound can get similar diagnostic performance as FNAB. The diagnostic results of FNAB included Bethesda class II and more than V which are defined as benign and malignant, respectively.

Thyroid Disease and Chronic Periodontitis

Thyroid DiseasesChronic Periodontitis

Currently, the investigators are unaware of any previous studies that have analyzed the relationship between the prevalence of thyroid disease and chronic periodontitis among adults utilizing a retrospective, cross-sectional design. This study will review approximately 2000 patient records and compare the prevalence of thyroid disease in three groups with increasing severity of chronic periodontitis.

Association of Oral Lichen Planus and Thyroid Disease

Oral Lichen PlanusThyroid Diseases

Thyroid disease is a common endocrine disorder. Oral lichen planus (OLP) is a chronic autoimmune disease that occurs on the oral mucosa in 1-2% of the general population.The purpose of this study was to determine whether there is an association between thyroid disease and oral planus lichen in the population of our patients. In the last few years, a couple of studies have been published in the world literature that have studied the possible association of these diagnoses in different populations. Most of the results showed a higher prevalence of thyroid disease in the population of lichen patients, compared with patients without lichen, although some results are contradictory. Some authors believe that the onset of OLP precedes thyroid dysfunction. In the population of Croatian patients with lichen, no research has been done to study the possible connection between these two diseases. The obtained results could help clarify whether there is a connection between these two diagnoses in the population of our lichen patients and enable earlier detection of patients with thyroid hypofunction.

Cholesterol Metabolites Analysis in Human Thyroid and Iodine Resistance

Thyroid Cancer

The study team previously shown that a cholesterol metabolite, dendrogenin A (DDA) differentiates anaplastic thyroid cancer cell lines and that its mRNA expression is diminished in human radioiodine refractory thyroid cancer samples. The team aim to quantify via mass spectrometry and immunohistochemistry DDA and other cholesterol metabolites in thyroid cancer versus healthy thyroid tissue human samples.

A Nomogram Model to Predict Central Lymphnode Metastasis in Thyroid Papillary Carcinoma

Thyroid Papillary Carcinoma

To establish and validate a suitable and practical nomogram for primary hospitals to predict the risk of central lymph node metastasis (CLNM) among thyroid papillary carcinoma (PTC) patients based on clinical and ultrasound characteristics among Chinese population,1000 PTC patients were retrospectively reviewed who underwent bilateral thyroidectomy or lobectomy plus central lymph node dissection(CLND) between June 2014 and September 2019 in Sun Yat-sen Memorial Hospital (Guangzhou, South China), and then LASSO regression analysis was performed to screen out the possible predictors. Another 200 PTC patients from the First Affiliated Hospital of Zhengzhou University (Zhengzhou, North China) who underwent bilateral thyroidectomy or lobectomy plus CLND between March 2019 and November 2020 were enrolled to construct the nomogram. The area under the receiver operating characteristic (ROC) curves (AUC), calibration curves and decision curve analysis (DCA) were used to evaluate the nomogram.

In Vivo Multispectral Optoacoustic Imaging of Thyroid Nodules

Thyroid Nodule

Thyroid nodules are common in clinical practice. Head and neck ultrasound is recommended as a routine examination for all patients with thyroid lesions. The Thyroid Imaging Reporting And Documentation System (TIRADS) criteria helps to estimate the risk of malignancy based on ultrasound patterns and nodule sizes guiding the performance of fine-needle-aspiration (FNA). Approximately 20% of FNA results cannot be specified whether being benign or malig-nant tissue. A definitive diagnosis can only be made from histopathology after diagnostic (hemi)thyroidectomy. However, (hemi)thyroidectomy has disadvantages as it leads to over-treatment and has a risk of postoperative morbidity (e.g. hypothyroidism and laryngeal nerve injury). Furthermore, (hemi)thyroidectomy is known to be associated with poor quality of life. Clearly, there is an unmet need for additional diagnostic tools in order to identify malignant thyroid nodules and thereby support the decision making for treatment of the thyroid. Multispectral optoacoustic tomography (MSOT) is an innovative, non-invasive imaging method currently available in the UMCG that enables visualization of endogenous chromophores and exogenous contrast agents using the generation of ultrasound waves due to light absorption by using high frequency pulsed laser light. Recently, this system has been used by other groups for non-invasive determination of thyroid nodules. Results show that multispectral optoacoustic imaging of thyroid nodules may distinguish benign from malignant nodules. However, most certainly, a larger cohort is necessary to confirm this finding.

Thyroid Function Tests and Status of Thyroid Autoantibodies in Covid-19 Patients

COVID-19 InfectionThyroid Function Tests2 more

COVID-19 infection causes a hypersensitive immune reaction and widespread inflammation through cytokines in various organs of the body, especially the lungs. This cytokine-mediated widespread inflammation can also affect the thyroid gland, causing thyroiditis and impaired thyroid functions. The researchers evaluated thyroid function tests and thyroid autoantibodies in patients hospitalized for COVID-19 infection. Researchers excluded patients on intensive care therapy and patients with known thyroid disease. The researchers examined the relationship of thyroid hormones and thyroid autoantibodies to COVID-19 disease, white blood cells, neutrophil / lymphocyte ratio, c reactive protein, fibrinogen, procalcitonin, ferritin, and D-dimer stages in these patients. Researchers compared changes in thyroid hormones and autoantibodies in people without COVID-19 infection and without thyroid disease.

The Impact of COVID-19 Pandemic on Thyroid Surgery in Italy: Results From a Nation-wide Multicentric...

Thyroid Disease

Italy has been on the frontline of the COVID-19 pandemic, caused by the coronavirus SARS-CoV-2, the need to focus resources to deal with the pandemic led to a disruption of routine surgical care, as well as activity for oncologic and chronic disease. The aim of this study was to evaluate the impact of COVID-19 pandemic on surgical activity of the Italian Units of Endocrine Surgery belonging to the SIUEC (Italian Society of Endocrine Surgery), the most important national scientific society of endocrine surgery.The aim of this study was to evaluate the impact of COVID-19 pandemic on surgical activity of the Italian Units of Endocrine Surgery belonging to the SIUEC (Italian Society of Endocrine Surgery), the most important national scientific society of endocrine surgery.

Near-infrared Fluorescence With Indocyanine Green for Identification of Sentinels and Parathyroids...

Thyroid CancerThyroid Carcinoma5 more

Indocyanine green (ICG) is a water-soluble organic dye that is cleared totally through the hepatobiliary system. It has a half-life of 3-4 mins, which allows repeated applications. Near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) imaging has been recently introduced, and has been suggested as a useful tool for the identification and preservation of the parathyroid glands (PGs) during total thyroidectomy (TT). ICG can also be used for sentinel lymph node (SLN) biopsy to predict the micrometastases in central lymph nodes (CLN) in thyroid carcinoma, and central lymph node dissection can reduce local recurrence.
