OBJECTIVES: Doppler ultrasound (US) has been widely used to evaluate the cervical venous system of multiple sclerosis (MS) patients according to the hypothesis of chronic cerebrospinal venous insufficiency (CCSVI) with contradictory results. Venous anatomy and pathology can be examined with less operator-dependent magnetic resonance imaging (MRI). DESIGN: To assess the inter-observer agreement in measuring internal jugular vein (IJV) cross-sectional area (CSA) in MR-images and to explore the agreement between US and MRI in the detection of calibres of ≤ 0...

Benign thyroid nodules are a common disease in the general population. Most often, they are completely asymptomatic and discovered occasionally during routine ultrasound examinations, and do not require any treatment. When thyroid nodules become symptomatic, surgical excision is still considered standard treatment. In the last few years, several experiences in the treatment of benign thyroid nodules through image-guided percutaneous thermal ablation have been reported with encouraging results, so that currently, these treatments are often proposed as first-choice options for patients with symptomatic benign thyroid nodules...

Since ancient times in South Tyrol there was evidence of endemic goitre caused by iodine deficiency. In the early 80's an epidemiological research on adults and primary and secondary school children reported in the least a prevalence of goitre from grade 1 B-3 (WHO) of 23,66% (limits WHO >5%) and an urinary iodine of 10,2 µgI/L. Therefore South Tyrol population presented heavy endemic goitre. In 1982 started a generalized iodine prophylaxis with alimentary iodined salt after an intense prevention campaign...

Brain-lung-thyroid syndrome (OMIM #610978) is associated with mutations in the NK2 homeobox 1 (NKX2-1) gene, a transcription factor important in development. 50% of patients are affected by the full triad, comprising congenital hypothyroidism, benign hereditary chorea and infant respiratory distress syndrome. Four cases have previously been reported where a patient has features consistent with brain-lung-thyroid syndrome and a chromosome 14q13 deletion adjacent to, but not disrupting, NKX2-1. We present a patient who has a phenotype consistent with brain-lung-thyroid syndrome, featuring congenital hypothyroidism and choreoathetoid movements with gross motor delay...

BACKGROUND: Real-time elastography has been proposed to increase the sensitivity of ultrasound and improve the detection of thyroid nodules at risk of malignancy. To date sparse data on real-time elastography assessment of autonomously functioning thyroid nodules exist. Here, we investigated the potential role of real-time elastography in autonomously functioning thyroid nodule assessment. Specifically, the correlation between serum hormones and real-time elastography score, as well as other clinical and ultrasound features, was analyzed...

The British Thyroid Association recommended in new guidelines on thyroid cancer treatment [Kwak et al. (Korean J Radiol 14:110-117, 2013)] that ultrasound grading of thyroid nodules should be incorporated into MDT management. A retrospective study was carried out to determine that the impact of US grading has had on MDT decision making in practice. The design used in the study is a retrospective review of case notes. The study was carried out in the hub hospital for thyroid cancer in the North west London Cancer network...

A 67-year-old woman was referred for a bone scan for evaluation of increasing serum alkaline phosphatase levels. Bone scan revealed no abnormal uptake in the skeleton. However, intense hypervascularity and delayed tracer uptake were incidentally identified in an enlarged right thyroid gland. A thyroid scintigraphy, contrast-enhanced CT of the neck, and sonographic evaluation of the abnormality were subsequently organized to characterize the lesion. An ultrasound-guided fine-needle aspiration revealed a benign follicular pattern (Bethesda II), and histopathology of the right hemithyroidectomy confirmed a dominant nodule within a nodular goiter...

BACKGROUND: Thyroid incidentalomas (TI) are highly prevalent asymptomatic thyroid nodules with ultrasound as the best imaging modality for their detection and characterization. Although they are mostly benign, potential for malignancy is up to 10-15%. In sub-Saharan Africa little data exists on the prevalence and risk categorization of TI. The aim of this study was to determine the prevalence and ultrasound characteristics of non-palpable thyroid incidentalomas among adults in sub-Saharan setting...

Obesity and thyroid function are closely related. Thyroid hormones are involved in the regulation of metabolism, thermogenesis, food intake, and fat oxidation. In obese children the most frequent hormonal abnormalities are slight hyperthyrotropinaemia and moderate increases in total T3 and/or fT3 concentrations. Those abnormalities are usually considered a cause of obesity, but according to recent studies, they should actually be considered an adaptation process aimed at increasing resting energy expenditure and total energy expenditure...

Introduction. Selenium is a micronutrient embedded in several proteins. In adults, the thyroid is the organ with the highest amount of selenium per gram of tissue. Selenium levels in the body depend on the characteristics of the population and its diet, geographic area, and soil composition. In the thyroid, selenium is required for the antioxidant function and for the metabolism of thyroid hormones. Methods. We performed a review of the literature on selenium's role in thyroid function using PubMed/MEDLINE...
