OBJECTIVES Acromegaly is frequently associated with thyroid diseases. In this study, we evaluated the frequency of thyroid disorders in a series of acromegalic patients. SUBJECTS AND METHODS We evaluated 106 acromegalic patients using thyroid ultrasonography (US) and measurements of GH, IGF-I, free T4, TSH and anti-thyroperoxidase antibody levels. IGF-I was expressed in mass units and age-rel...

Background: Thyroid masses are common, especially in areas of iodine deficiency. Mediastinal goiter is defined by the presence of enlarged thyroid tissue below the level of the thoracic inlet. This study aimed to evaluate the presentation, diagnosis, treatment, histopathological findings and complications of patients with mediastinal goiter or masses. Materials and Methods: This was a descripti...

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...

Thyroid complications resulting from excess iodide such as thyrotoxicosis, thyroiditis, sialadenitis, or hypothyroidism are much rarer after iodine supplementation with Lipiodol than with KI. They do not militate against its widespread use in endemic goiter populations, especially in pregnant women. However, patients with multinodular goiter should not be treated or should be treated only under...

INTRODUCTION Despite long standing iodine supplementation in Iran the prevalence of goiter remains high in some areas. This may suggest that causes other than iodine deficiency, such as autoimmune thyroid diseases, should also be considered. We therefore assessed the prevalence of anti-thyroid antibodies in children living in an inland area in Iran and correlated these findings with prevalence ...

Aim: To compare patients with toxic and non-toxic nodular/multinodular goiter in terms of clinical, sonographical cytological features.
 Material Method: The medical data 326 were reviewed retrospectively. Clinical sonographic features examined. Four hundred eighty-one nodules compared sonographically cytologically. One twenty-four had nodular 202 them goiter.
 Results: group was olde...

Intrathoracic goiter is commonly located in the anterior mediastinum. Here we report a case of a 58-year-old Chinese male in whom we successfully removed the intrathoracic goiter and eased his dyspnea by a right posterolateral thoracotomy approach. Posterior mediastinal thyroid goiter with mediastinal compressive symptoms is an indication of surgery.

BACKGROUND Endemic goiter is present in most parts of Iran. Iron deficiency adversely affects the physiology of thyroid. The initial steps of thyroid hormone synthesis are catalyzed by thyroperoxidases and are dependent on iron. In many developing countries, children are at high risk of both goiter and iron deficiency anemia. In addition, iron deficiency may alter central nervous system control...

Standard methods including pharmacotherapy, radioiodine and surgery cannot always be applied in treatment of thyroid diseases. The limitations of these methods are: drug intolerance and their side effects, too low radioiodine uptake, high risk of surgery. The obliteration of thyroid arteries seems to be an alternative method which could be used in the stiuation of ineffective standard treatment...

Dr. med. Josef Evers, KfH Dialysezentrum, Dorotheenweg 3, D-53474 Bad Neuenahr (Germany) Dear Sir, Various alterations of thyroid hormones, mostly decreased levels of total thyroxine (T4) and triiodothyroxine (T3) in serum, and a blunted, delayed rise of thyroid-stimulating hormone (TSH) after administration of thyrotropin-releasing hormone (TRH) have been found in patients with renal failure [...
