We assessed the iodine nutrition of upper socioeconomic strata school children from Delhi to identify its association with goiter, thyroid autoimmunity or thyroid function. After informed consent of parents, all assenting students (n=997) from one randomly selected section of each class from five private schools representing all the zones of Delhi) were evaluated for goiter, urinary iodine excr...

The radiologist needs to be aware of a potential pitfall that can influence the imaging appearance of thyroid goiter. Whether the patient is imaged with the arms overhead or by the side may affect the apparent mediastinal excursion of a goiter. CT scans obtained with the patient's arms by the side are more accurate for determining substernal extent of goiter than when the arms are overhead, a p...

1414 school children (789 boys and 625 girls) residing in east-Tehran, were evaluated for the evidence of goiter. 88% of girls and 71.5% of boys had goiter. In 30% of girls and 17.5% of boys goiter was clearly visible (grade 2 and over). FT4I, FT3I, TSH, and thyroglobulin concentrations were not significantly different in groups with or without goiter. The concentration of iodide in urine was 2...

Iodine deficiency remains a considerable challenge worldwide, even after decades of efforts to address the problem. The aim of this review is to present the current situation in historically iodine-deficient Pakistan regarding iodine nutritional status and place it in a global perspective. We collected relevant articles from online bibliographic databases and websites of concerned organizations...

Goiter is more common in women, suggesting that estrogen could be involved in its physiopathology. The presence of classical estrogen receptors (ERα and ERβ) has been described in thyroid tissue, suggesting a direct effect of estrogen on the gland. A nonclassic estrogen receptor, the G-protein-coupled estrogen receptor (GPER1), has been described recently in several tissues. However, in goiter,...

We carefully assessed thyroid status and goiter by ultrasound in 1411 subjects virtually representing the entire resident population of Pescopagano, an iodine-deficient village of Southern Italy. Median urinary iodine excretion was 55 microg/L. The prevalence of goiter was 16.0% in children and 59.8% in adults. Thyroid nodularity was 0.5% in children and progressively increased with age to 28.5...

Haizao Yuhu Decoction (HYD), a famous multi-component herbal formula, has been widely used to treat various thyroid-related diseases, including iodine-deficient goiter. Herb pair Thallus Sargassi Pallidi (HZ) and Radix Glycyrrhizae (GC), one of the so-called "eighteen antagonistic medicaments", contains in HYD. To explore pharmacological mechanisms of HYD acting on iodine-deficient goiter and t...

The RAS protooncogene has an important, although not yet established role in thyroid neoplasia. In this study, we evaluated the H-RAS mRNA and protein levels in human samples of nontoxic and toxic multinodular goiter samples, according to serum TSH levels. The mean of H-RAS mRNA levels in nodules of nontoxic nodular goiter were significantly increased compared to nonnodular tissue (1.49+/-1.21 ...

OBJECTIVES To report a new phenotype of advanced endemic goiter that affects only one lobe of the thyroid gland. PATIENTS AND METHODS This study included 60 patients from the west of Sudan with long-standing unilateral simple endemic goiter that required obectomy, with emphasis on the gross appearance, measurements and cytological features of the contralateral lobe. RESULTS Out of 60 patien...

We report a case of polyglandular autoimmune syndrome (PGA) complicated by Duane's syndrome. The patient was 44-year-old female with marked limitation of abduction in the left eye, lethargy, nonhomogeneous facial pigmentation, goiter, and oligomenorrhea. A diagnosis of chronic thyroiditis was first made to explain the patient's symptoms. Laboratory examinations were performed. Plasma ACTH level...
