Thyroid tissue located within the upper airway has received only sparse attention in the English literature. Aberrant benign thyroid masses may present as either an unrelated autopsy finding or with symptoms such as dyspnea, hemoptysis or adult -onset asthma. There is no place for medical management in the therapy of these lesions, although the appropriate surgical procedure is not clearly ...

BACKGROUND Thyroid hemiagenesis is a rare congenital anomaly in which 1 thyroid lobe fails to develop. Co-occurrence of hemiagenesis and thyroid carcinoma is extremely rare. Here, we report 2 cases of thyroid hemiagenesis with carcinoma. METHODS The first patient was referred with a left thyroid mass and absent right lobe. The frozen section examination revealed medullary thyroid carcinoma (M...

The aim of this report is to present a new two-piece thyroid-neck phantom produced by the concurrent use of epoxy resin and poly(methyl methacrylate) (PMMA: plexiglass) soft tissue equivalent materials. Accordingly, mass attenuation coefficients of the epoxy resin and the plexiglass compounds were obtained from simulation (NIST XCOM 3.1) and measurements (practical dosimetry) and compared to th...

The presence of specific receptors for synthetic growth hormone secretagogues (GHSs) has been investigated in non-tumoral and neoplastic human thyroid tissue using a radio-iodinated peptidyl GHS ((125)I-labelled Tyr-Ala-hexarelin) as ligand. Specific binding sites for Tyr-Ala-hexarelin were detected in membranes from non-tumoral and follicular-derived neoplastic thyroid tissue, but not in thyro...

1. Coincident progressive and regressive changes are induced in the tail of the frog larva by simultaneous thyroid administration and removal of a portion of the tail. The rate of growth of the regenerating tail is greatest in animals not treated with thyroid, next greatest in animals treated with thyroid 2 days after tail removal, somewhat less in animals treated with thyroid simultaneously wi...

Purpose: There are no effective therapies for patients with poorly differentiated papillary thyroid cancer (PTC) or anaplastic thyroid cancer (ATC), and metastasis to the bone represents a significantly worse prognosis. Src family kinases (SFKs) are overexpressed and activated in numerous tumor types and have emerged as a promising therapeutic target, especially in relation to metastasis. We re...

introduction:  in order to assess echocardiographic left ventricular functional indices in patients with differentiated thyroid carcinoma (dtc), after l-t4 withdrawal (short-term overt hypothyroidism) and during tsh suppressive therapy, we have evaluated cardiac hemodynamics in a single cohort study. methods: 24 patients with dtc were studied in two phases: 1: at least 4 weeks after l-t4 withdr...

Tissue samples of thyroid glands of 16 healthy camels (Camelus dromedarius) were investigated under two age groups i.e. group A (3-5 years) and group B (6-10 years)) with equal number of animals, for their gross and microscopic anatomy. Gross studies revealed that thyroid glands were located near the first ring of trachea and had two lobes, connected by an isthmus. They were of reddish brown in...

A serious hazard to patients during orthotopic liver transplantation is hyperkalemia. Although the most frequent and hazardous hyperkalemia occurs immediately after reperfusion of the newly transplanted liver, morbid hyperkalemia could happen in the other phases during orthotopic liver transplantation. However, pre-anhepatic hyperkalemia during orthotopic liver transplantation is rare. This rep...
