The great apes include, in addition to Homo, the genera Pongo (orangutans), Gorilla (gorillas), and Pan, the latter comprising two species, P. troglodytes (chimpanzees) and P. paniscus (bonobos). Adult-onset hypothyroidism was previously reported in 4 individual nonhuman great apes. However, there is scarce information on normal serum thyroid hormone levels and virtually no data for thyroid aut...

Antibody-dependent macrophage-mediated cytotoxicity was studied to determine the significance of cytophilic anti-thyroglobulin antibody (ATgA) present in the sera of patients with Hashimoto's thyroiditis. Effector cells were normal human monocytes or guinea-pig peritoneal exudate cells, and target cells were human thyroglobulin(Tg)-coated chicken erythrocytes. Cytotoxicity was evaluated by morp...

PURPOSE We investigated the incidence and risk factors of hypothyroidism after thyroid lobectomy, and evaluated the possibility to predict hypothyroidism preoperatively with serologic markers, such as thyrotropin (TSH), thyroglobulin (TG), anti-thyroglobulin (ATA), and anti-microsomal antibody (AMA). METHODS We enrolled 123 consecutive patients who underwent thyroid lobectomy due to benign co...

BACKGROUND AND OBJECTIVE Thyroglobulin in the needle washout (Tg-FNA) and cytology of fine needle aspiration (cyto-FNA) are recommended for diagnosis of metastatic lymphadenopathies and recurrence of differentiated thyroid cancer. The objective of this study was to assess the value of these procedures in 16 cervical masses from patients with thyroid cancer of the follicular epithelium (TC). P...

Breast cancer is a hormone-dependent neoplasm. Conflicting results regarding the clinical correlation between breast cancer and thyroid diseases have been reported. The aim of this study was to determine the goiter prevalence, thyroid hormones and antithyroid antibody levels in patients with breast cancer. For this purpose, thyroid ultrasonography was performed and serum levels of free triiodot...

OBJECTIVES Following iodisation in Sri Lanka we observed a high prevalence of thyroglobulin antibodies (TgAbs) in type 1 diabetic (T1DM) patients. The clinical significance of these TgAbs is uncertain. We sought to obtain a detailed epitope analysis of TgAbs in T1DM patients recruited from diabetes clinics and to compare these with TgAb epitope specificities in patients with autoimmune thyroid ...

BACKGROUND Thyroglobulin measurement in the washout of the needle used in fine-needle aspiration cytology (FNAC) has been proposed for the early detection of lymph node metastasis both in patients with or without serum thyroglobulin antibodies; however, up to now, there have been no reports that recombinant human thyrotropin (rhTSH) stimulation modifies thyroglobulin measurement in lymph node a...

BACKGROUND Knowing the postsurgery thyroglobulin (Tg) kinetic would enable its rationale for use in patients with differentiated thyroid cancer (DTC). Heterogeneous results were previously reported, then we aimed to evaluate the postsurgery Tg kinetic in a large group of patients with DTC. METHODS Enrolled were 96 patients with DTC. Serum Tg was measured first at 5 minutes, then at 24, 48, 72...

It is worthwhile to measure serum thyroglobulin (TG) level in thyroid cancer before subjecting patients to surgery for two reasons. Firstly, if the level is high, it may give a clue to the local and metastatic tumour burden at presentation; secondly, if the level is normal, it identifies the patients who are unlikely to show rising TG levels in the presence of thyroid cancer. Those who have hig...
