Predictors of bethesda i category in thyroid fine needle aspiration cytology

Rodrigues Catarina , Benido Silva Vania , Puga Francisca , Freitas Claudia , Couto Carvalho Andre

Introduction: Fine needle aspiration cytology(FNAC) is the mainstay for evaluation of nodular thyroid disease. Internationally reported prevalence for Bethesda I(unsatisfactory sample) category is 5-60%. Several factors may determine this result, including patient and nodules’ features as well as both FNAC performer and pathologists’ skills. Few studies have evaluated pre-procedure factors associated with unsatisfactory cytology results. If present, recognizing these...

Diverse clinical and laboratory phenotypes associated with heterozygous PAX8 mutations

Ravikumar Vikashini , Peters Catherine , Cerbone Manuela , Bhushan Arya Ved , Agrawal Pankaj , Katugampola Harshini , Langham Shirley , Schoenmakers Erik , Schoenmakers Nadia

Introduction: Paired box gene 8 (PAX8) is a key transcription factor required both for normal fetal thyroid development and maintenance of the differentiated thyroid phenotype, mediating transcriptional activation of SLC5A5, TG, and TPO, and synergizing with NKX2-1 at the TG promoter. Heterozygous PAX8 mutations are a rare but well-recognized cause of congenital hypothyroidism (CH) due to thyroid dysgenesis (TD), and are classically associated with thyroid hypoplasia. However,...

Association between ultrasonographic findings and thyroid function in autoimmune diffuse thyroid disease in children and adolescents

Min Hwang Sook , Eun Park Ji

Purpose: To evaluate the association between ultrasonography (US) feature of thyroid gland and thyroid function in pediatric and adolescent populations with autoimmune diffuse thyroid diseases (AITD).Methods: From 2000 to 2020, we reviewed thyroid ultrasound (US) images and thyroid function statuses in 133 children and adolescent AITD patients. Our review of the images focused on decreased echogenicity and heterogeneity, which were classified into four g...

Diagnostic performance of 18F-choline PET/CT for detection of hyperfunctioning parathyroid glands in patients with primary hyperparathyroidism: a single-center experience

Heo Jung , Park Hyunju , Hyuk Kim Tae , Hoon Chung Jae , Wook Kim Sun , Yang Heera , Soo Kim Jee , Ho Choe Jun , Han Kim Jung , Seok Cho Young , Young Choi Joon

Objectives: 18F-choline PET/CT is a recently introduced imaging modality to localize hyperfunctioning parathyroid glands in patient with hyperparathyroidism. But there has been no study according the diagnostic power of 18F-choline PET/CT in Korea so far owing to its limited distribution. Therefore, we evaluated the diagnostic performance of 18F-choline PET/CT in detection of hyperfunctioning parathyroid gland in patients with primary hyperpara...

Radiomics analysis of thyroid ultrasound in relation to the radioactive iodine therapy-related sialadenitis

Hyun Lee Da

Objective: Patients with thyroiditis often have sialadenitis. Radioactive iodine therapy (RAIT) sialadenitis could lower the patient’s quality of life. However, it had not been investigated about the occurrence of RAIT sialadenitis and the presence of underlying thyroiditis. Therefore, we analyzed the preoperative thyroid ultrasound (US) with radiomics to figure out the occurrence of the RAIT sialadenitis.Materials and Methods: In this retrospective...

Does hypoechogenicity, as a single variable in decision of FNA, offer similar sensitivity and specificity as the elaborate tirads in the 10-20 mm range of thyroid nodules for cancer detection?

Solymosi Tamas , Joop Bonnema Steen , Frasoldati Andrea , Hegedus Laszlo , Laszlo Jambor Dr , Karanyi Zsolt , Laszlo Kovacs Gabor , Papini Enrico , Rucz Karoly , Russ Gilles , Nagy Endre

Background: Widespread use of imaging has led to the detection of an increasing number of thyroid nodules. Thyroid societies have recommended the use of Thyroid Imaging, Reporting and Data System (TIRADS). However, there is a multitude of such risk stratification systems (RSS) for selecting thyroid nodules for FNA. They may be time consuming and consensus on thyroid nodule descriptors lacks. Also studies have suggested that operators’ experience may not be inferior to usi...

Ultrasound and cytological evaluation of PET-CT positive incidental thyroid lesions

Nonchev Boyan , Argatska Antoaneta , Chobankova Elena , Dimov Rosen , Chonov Veselin

Introduction: Positron emission tomography - computed tomography (PET-CT) is a highly sensitive imaging modality for evaluating a variety of conditions, including detection of cancer and potential metastases. PET-CT positive thyroid lesions are found incidentally in about 2.5 % of the scans. They can be focal or diffuse and as they pose a considerably high risk of malignancy further diagnostic tests such as neck ultrasound and fine-needle aspiration biopsy (FNAB) are recommend...

Assessment of thyroid stiffness in beta thalassemia patients by using shear-wave ultrasound elastography

Unluturk Uğur , Hanife Oğuz Seda , Mammadlı Khalid , Unal Cangul Şule , Sayınalp Nilgun , Ruhi Onur Mehmet

Objective: Beta thalassemia is associated with a number of endocrinopathies. Iron overload is thought to be at the root of thalassemia-related endocrinopathies, including hypothyroidism; however, morphologic changes that could be attributable to iron deposition in the thyroid gland have been under investigated. This study aims to evaluate thyroid gland volumes and stiffness in thalassemia patients using shear-wave ultrasound elastography (SWE), and to analyze if there is any r...

Thyroid antibodies and early response to treatment in graves’ disease

Tammelin Karin , Holmberg Mats , Filipsson Nystrom Helena

Objective: Some patients with Graves’ disease (GD) respond faster to antithyroid drugs (ATD) than others. Our aim was to study if levels of autoantibodies to the TSH-receptor (TRAb), thyroid-stimulating immunoglobulin (TSI), thyroid peroxidase antibodies (anti-TPO) and/or clinical factors influence the early response to anti thyroid drugs (ATD) in women with GD.Methods: This was a longitudinal cohort study of 65 women with GD and fT4 ≥50 pmol/...
