Comparison of different systems of ultrasound (US) risk stratification for malignancy in elderly patients with thyroid nodules. Real world experience.

Purpose: To comparatively assess the performance of three sonographic classification systems, American Thyroid Association (ATA), the American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS), and American Association of Clinical Endocrinologists (AACE)/American College of Endocrinology (ACE)/Associazione Medici Endocrinologi (AME) in identifying malignant nodules in an elderly population.

Methods: Cross-sectional study of patients referred for fine needle aspiration biopsy in an academic center for the elderly. One nodule/patient was considered.

Differential profile of ultrasound findings associated with malignancy in mixed and solid thyroid nodules in an elderly female population.

Objective. Ultrasonographic characteristics are associated with thyroid malignancy. Our aim was to compare the diagnostic value of ultrasound features in the detection of thyroid malignancy in both solid and mixed nodules.

Internal jugular vein valve incompetence is highly prevalent in transient global amnesia.

Background And Purpose: Transient global amnesia (TGA) is the inability to retain new information and to recall past events during a period of minutes or hours. Its etiology is unclear, and flow disturbances in the mesial temporal lobes secondary to venous congestion have been proposed as a potential cause. Ultrasonographic evaluation of the internal jugular vein (IJV) has demonstrated valvular insufficiency in TGA.

Evaluation of innovative skin-marking technique performed before thyroid ultrasound-guided fine-needle aspiration biopsies.

Objective: To introduce an innovative skin-marking technique performed before ultrasound-guided fine-needle aspiration biopsy (US-FNAB) of the thyroid.

Methods: We studied 248 patients with thyroid nodules, who were classified on the basis of physical examination into two groups-those with palpable nodules (N = 127) and those with nonpalpable or difficult-to-palpate nodules (N = 121). Each group was further subdivided according to the size of the thyroid nodule (< or = 15 mm versus >15 mm).
