Association of obesity and diabetes with thyroid nodules

2017

Aim: There are conflicting data concerning the possibility that obesity and diabetes raise the risk of thyroid nodules. The incidence of thyroid nodules is increasing, as is that of obesity and diabetes; therefore, understanding whether these metabolic and nutritional disorders influence nodular thyroid disease is important for organizing prevention strategies. This study investigated the association between thyroid nodules, obesity, diabetes, and dietary habits. Materials and methods: A cohort of randomly selected adults (455 males, 746 females; age: 18–90 years) living in Palermo (Italy), a mild iodine deficiency area, was cross-sectionally investigated. Participants underwent high-reso…

Incidentally discovered thyroid nodules: incidence, and greyscale and colour Doppler pattern in an adult population screened by real-time compound sp…

2006

Purpose. Our aim was to assess the incidence and ultrasound features of thyroid nodules in an adult population screened by means of high-resolution ultrasonography (HRUS) and to evaluate the contribution of real-time spatial compound sonography (CS) in terms of image quality. Materials and methods. A total of 704 consecutive patients (400 women, 304 men) without thyroid disease underwent HRUS and CS examination of the thyroid gland. Number, size, location, echotexture and colour Doppler pattern of detected nodules were assessed. Two radiologists also assessed image quality of the two techniques. Results. Seven hundred and eleven thyroid nodules (size range 0.18-4.1 cm; mean: 1.1 cm) were de…

Improving Diagnostic Performance for Thyroid Nodules Classified as Bethesda Category III or IV: How and by Whom Ultrasonography Should be Performed

2020

Background: The purpose of this prospective study is to evaluate if the association of Bethesda system and a 3-categories Ultrasonography (US) risk stratification system proposed by the American Association of Clinical Endocrinologists/American College of Endocrinology/Associazione Medici Endocrinologi improves the performance of cytology alone in III or IV categories and if further variables such as US provider (radiologist; endocrinologist, or endocrine surgeon both coming from a dedicated team) influence the accuracy of the diagnostic. Methods: 570 consecutive patients with complete clinical records, affected by Bethesda III or IV nodules, have been addressed to two public referral surgi…

Suspicious liver nodule in chronic liver disease: Usefulness of a second biopsy

2018

International audience; Purpose: To assess the usefulness of a second biopsy when the first one was inconclusive in patients with a liver nodule found during the follow-up for chronic liver disease.Materials and methods: Among 381 patients (544 nodules) included in a prospective study designed to evaluate the accuracy of imaging for the diagnosis of small hepatocellular carcinoma (HCC) in chronic liver disease, 254 nodules were biopsied. The following histological results were considered as conclusive: HCC, dysplastic or regenerative nodule, and other identified tumors (benign or malignant). For nodules with inconclusive results (e.g. fibrosis or no definite focal lesion), a second biopsy w…

Oral verruciform xanthoma : report of 13 new cases and review of the literature

2018

Background Oral verruciform xanthoma (OVX) is a rare lesion. The purpose of the present study is to describe the clinical features of 13 OVXs and review all cases reported in the English literature. Material and Methods Thirteen cases of OVX diagnosed during a 47-year period were retrospectively collected. The patients’ gender and age, as well as the main clinical features of the lesions were retrieved from the biopsy request forms. Pubmed®, Scopus® and Google ScholarTM electronic databases were searched with the key word “verruciform xanthoma”. Only cases of histologically confirmed OVX were included in the study. Results The 13 OVXs represented approximately 0.04% of 35,617 biopsies acces…

European perspective on the 2015 American Thyroid Association Management Guidelines for Adult Patients with Thyroid Nodules and Differentiated Thyroi…

2018

The American Thyroid Association (ATA) management guidelines for patients with thyroid nodules and differentiated thyroid cancer (DTC) are highly influential practice recommendations. The latest revision appeared in 2015 ("ATA 2015"). These guidelines were developed predominantly by North American experts. European experts frequently have different perspectives, given epidemiological, technological/methodological, practice organization, and medicolegal differences between the respective regions.Divergent viewpoints were the focus of an invited symposium organized by the European Association of Nuclear Medicine involving 17 European thyroidologists, four ATA Guidelines Taskforce members, and…

Possible link between Hashimoto's thyroiditis and oral lichen planus: a novel association found

2013

Objectives: Hashimoto's thyroiditis as well as lichen planus has been associated to a number of disorders, generally of auto-immune origin. A novel possible association between oral lichen planus (OLP) and Hashimoto's thyroiditis (HT) is here proposed on the basis of a cross-sectional survey. Materials and methods: One hundred and five unrelated OLP patients were considered. Diagnosis of HT was based on positive serum anti-TPO, anti-Tg, TSH levels and the typical ultrasound pattern of the thyroid gland. Results: In the present survey, the prevalence of HT in the OLP group was 14. 3 % whereas the prevalence of HT-related hypothyroidism in the general population was reported to be equal to 1 …

Lung nodule 25 years after lobectomy - recurrence of bronchial carcinoid

2020

OBJECTIVE Introduction: Bronchopulmonary (BP) carcinoids are low and intermediate grade tumors, seen in adults between fourth to sixth decade, where no clear association with tobacco smoking is established. Most often they are sporadic lesions (95%). Half of patients have no symptoms and the tumor is incidentally found on a chest x- ray. BP carcinoids have a good prognostic, however there is a risk of distant metastasis and the recurrences are frequent. Therefore a crucial role of vigilant follow- up, extending far beyond 5 years. PATIENTS AND METHODS Case presentation: We report a case of 73 years old women, with history of recurrent pulmonary infections, and positive family history for lu…

2016

Background Transcatheter aortic valve implantation (TAVI) has become the treatment of choice in patients with severe aortic valve stenosis who are not eligible for operative replacement and an alternative for those with high surgical risk. Due to high age and smoking history in a high proportion of TAVI patients, suspicious findings are frequently observed in pre-procedural chest computer tomography (CCT).

Mature teratoma of the uterine corpus with thyroid differentiation

2000

A case of a clinically silent mature teratoma of the uterine corpus is reported. A 55-year-old woman presented with multiple uterine leiomyomas. The discovery was incidental, because the patient was asymptomatic. Macroscopically, a colloid-hemorrhagic-looking nodule was present. Histologic and immunohistochemical studies showed that this tumor was a small thyroid mass. Key words:,
