BACKGROUND/AIM Increasing evidence is available about the role of prolactin in the development of various cancers. The purpose of this study is to evaluate the frequency of thyroid cancer in patients with prolactinoma followed at a single site. MATERIALS AND METHODS The medical records of 182 patients diagnosed with prolactinoma were reviewed retrospectively. Serum prolactin, antithyroglobuli...

OBJECTIVE To report the clinical and molecular aspects of a patient with a diagnosis of Resistance to Thyroid Hormone (RTH) harboring the E449X mutation associated with autoimmune thyroid disease and severe neuropsychomotor retardation. METHODS We present a case report including clinical and laboratory findings, and molecular analysis of a Brazilian patient with RTH. RESULTS A 23-year old m...

To investigate whether circulating thyroglobulin (Tg) messenger ribonucleic acid (mRNA) and sodium/iodide symporter (NIS) mRNA transcripts in peripheral blood are valuable in the follow-up of patients with thyroid cancer, we developed highly sensitive nested Tg and NIS mRNA detection assays and compared their accuracy with serum thyroglobulin (sTg) and whole body scan with 131I during the monit...

OBJECTIVE To assess whether FDG PET could localize the recurrent or metastatic lesions in papillary thyroid cancer patients with negative radioiodine scan. METHODS Whole body PET was performed after injecting 370-555 MBq of 18F-FDG in 108 patients, who were suspected of having recurrence or metastasis and whose 131I whole body scans were negative. Recurrence or metastasis occurred in 63 patie...

Alpha interferon (alphaIFN) therapy is known to induce thyroid autoimmunity in up to 40% of patients. The mechanism is unknown, but Th1 switching has been hypothesized. The aim of our study was to examine whether alphaIFN accelerated the development of thyroiditis in genetically susceptible mice. We took advantage of NOD-H2h4, a genetically susceptible animal model, which develops thyroiditis w...

A 57-year-old woman came to our hospital with complaints of neck swelling and headache in 1991. She was diagnosed as having chronic thyroiditis in euthyroidism because she had a diffuse goiter with both antithyroglobulin antibody (TGHA) and antimicrosomal antibody (MCHA). In 1992, she complained of the rapid growth of her thyroid gland and a swallowing disturbance. Atypical lymphocytes were obs...

Objective: The clinical diagnosis of autoimmune thyroid diseases (AITD) is usually confirmed by detection of various antibodies in the patient’s blood or by histopathological evaluation. In this study, we evaluated the prevalence of serum antibodies in histopathologically proven AITD and assessed the correlation between antibodies and thyroid dysfunction. Methods: 100 consecutive patients with ...

BACKGROUND The prevalence of hypothyroidism in Iran is unknown. The aims of the present study were to estimate the prevalence of overt and subclinical hypothyroidism among the adult population of Isfahan, a large metropolitan city in Iran, 15 years after universal salt iodization. METHODS A cross-sectional survey was conducted from January 2006 through April 2006. The selection was conducted ...

RATIONALE Hysterosalpingography (HSG), a standard procedure for the evaluation of women with infertility and repetitive pregnancy loss, is associated with complications such as uterine perforation, infection, allergic reactions, syncope, hemorrhage and shock, and pulmonary or retinal embolus. However, hyperthyroidism has not been reported as one of its complications. PATIENT CONCERNS AND DIAG...

Antithyroglobulin antibodies (TgAb) were measured using a chemiluminescent immunoassay (ICMA) and an agglutination test. TgAb laboratory and clinical interference with Tg measurements were assessed. The course of TgAb concentration and disease status were compared during 3 years after initial treatment. The agglutination test failed to detect all titers < 10 IU/mL (ICMA). Interference from TgAb...
