A case of parasitic thyroid nodule is presented. The patient was a non symptomatic 53-year-old white woman, on irregular course of L-thyroxine to treat hypothyroidism due to Hashimoto's thyroiditis. Without a history of thyroid trauma or surgery, she presented a 1.6 x 0.7 x 0.5cm right pre-laryngeal lymph node-like mass which, on ultrasonography, appeared distinct from the gland. TSH, thyroid p...

We investigated thyroid function and urinary iodine concentration (UIC) in seven patients with severe motor intellectual disabilities. All seven received total enteral nutrition (TEN) for more than three years with a daily iodine intake of less than 20 µg. They were diagnosed as hypothyroidism due to iodine deficiency (HID) because of high TSH levels (7.6-82.3 µIU/ml), lower free T4 (FT4 0.4-1....

The dependent tumors exhibited minor chromosomal changes and thyroglobulin antigenicity similar to that of normal rat thyroid. The transitional tumors exhibited moderate chromosomal alterations and practically no thyroglobulin antigenicity. The autonomous tumors exhibited severe chromosomal alteration, numerically and/or structurally, and no detectable immunogenicity related to thyroglobulin. A...

Background: Serum thyroglobulin appears to be a sensitive marker of thyroid dysfunction in endemic goiter. However, its value as an indicator of thyroid status in children after the introduction of iodized salt has not been tested. Objective: The objective was to optimize and validate a thyroglobulin assay on dried whole blood spots and to evaluate thyroglobulin as an indicator of thyroid respo...

BACKGROUND AND PURPOSE Washout thyroglobulin provides evidence for metastatic or recurrent lesions, However, the cutoff value is still controversial. We investigated an optimized cutoff value and indication for the use of washout thyroglobulin from fine-needle aspiration in neck lymph nodes from preoperative or postoperative patients with well-differentiated thyroid cancers. MATERIALS AND MET...

Thyroid tissue obtained from 12 patients with Graves' disease and treated with thionamide drugs for 3-7 mo before subtotal thyroidectomy, from 12 patients with Graves' disease, similarly treated, and given 50 mug of triiodothyronine (T3) for 10 days before surgery, and from 12 euthyroid patients with solitary cold nodules was investigated to compare in vitro iodination of thyroglobulin in toxic...

Perinuclear type of antineutrophil cytoplasmic antibodies (p-ANCA) have been found in patients with periarteritis nodosa, Churg-Strauss arteritis, or pauci-immune idiopathic crescentic glomerulonephritis. Recently, the association of p-ANCA and normotensive renal failure, in patients with systemic sclerosis (SSc), was reported. We have studied the incidence of p-ANCA in patients with SSc and ha...
