Relative risk of cancer in sonographically detected thyroid nodules with calcifications.

Purpose: The aim of this prospective study was to evaluate the significance of sonographically detected thyroid calcifications in the diagnosis of thyroid cancer.

Methods: One hundred eighty-eight patients with thyroid disease, including 37 with thyroid cancer, were included in the study. Each patient underwent preoperative, high-resolution sonography to evaluate the thyroid gland for the presence of calcifications.

Gallbladder contraction after hormonal manipulations in normal subjects and patients under total parenteral nutrition.

Total parenteral nutrition (TPN) induces biliary dilatation, sludge and formation of gallstones. Cholecystokinin (CCK) induces gallbladder (GB) contraction. During thyrotropin-releasing hormone (TRH) testing for thyroid function, we observed that patients felt a strong micturition reflex attributable to smooth muscle contraction of the bladder.

Diagnosis of thyroid cancer in southwestern Greece.

A prospective study of 1,200 patients with thyroid disease was performed from 1983 to 1988 to appraise the reliability of various diagnostic techniques in patients with thyroid cancer. Histologic confirmation was obtained in 201 patients. By assuming that only solid lesions, single or multiple, represented malignancy, the sensitivity and specificity of ultrasonography was 4.
