Positron emission tomography (PET) and PET/computed tomography (PET/CT) with different tracers are imaging methods increasingly used in patients with thyroid and adrenal diseases. The aim of this article is to provide an overview based on literature data about the usefulness of PET imaging in this setting …

The relation of thyroid autoimmunity to miscarriage is an important issue that has attracted the interest of many investigators. A number of papers have been published so far, which include healthy women, women with recurrent miscarriage and those undergoing assisted reproductive techniques. Most studies have shown a significant positive association between the presence of thyroid autoantibodies and miscarriage rate…

Active transport of iodide into the thyroid gland is a crucial and rate-limiting step in the biosynthesis of thyroid hormones which play an important role in the metabolism, growth and maturation of a variety of organ systems, in particular the nervous system1. Although, iodide transport into the thyroid gland has been known …

The thyroid gland is dependent on dietary iodine for the production of thyroid hormones, normal iodine requirement being about 150-200μg/day. Long-term deficiency in iodine intake is associated with the development of goiter. When the prevalence of goiter in a population rises above 5-10%, the problem is considered endemic …

Autoimmune diseases are a group of heterogeneous disorders characterized by abnormal lymphocytic activation directed against self-tissues. Hashimoto’s thyroiditis (HT) and Graves’ disease (GD) are two of the most common clinical expressions of organ-specific autoimmunity …

The central neuroendocrine systems are responsible for the control of homeostatic processes in the body, including reproduction, growth, metabolism and energy balance, as well as stress responsiveness. These processes are initiated by signals in the central nervous system, specifically the hypothalamus, and are conveyed first by neural and then by endocrine effectors …

Thyroid cancer accounts for approximately 1% of total cancer cases in developed countries. It affects all age groups, although it is rare in children. Thyroid tumors are more frequent in women than in men. Despite their relative rarity they exhibit a wide range of morphological patterns and biological behavior which may explain the great interest in these neoplasms of both pathologists and clinicians…

OBJECTIVE: The association between Hashimoto’s thyroiditis (HT) and papillary thyroid carcinoma (PTC) remains controversial in medical bibliography. The main objective of our study was to determine the prevalence of PTC and HT coexistence in histopathologic material of thyroidectomized patients. DESIGN: In a retrospective study …

OBJECTIVE AND DESIGN: Sarcoidosis has been associated with thyroid diseases. However, until today no definite conclusions have been drawn. We aimed to assess the frequency of thyroid disorders and the levels of thyroid hormones and thyroid antibodies in 68 sarcoidosis patients and 75 controls …

OBJECTIVE: Adequate dietary iodine intake is necessary for normal thyroid gland function at all times, and most particularly during pregnancy. Increased iodine loss is cited, among other factors, as responsible for the increased iodine demand in this period. Our aim was to compare renal iodine excretion between …

Objective: The objective of this study was to compare various parameters in patients with hypothyroidism receiving either monotherapy with L-Thyroxine (L-T4) or combination therapy with L-T4 and L-Triiodothyronine (L-T3). Design: We conducted a randomized, controlled trial in 36 premenopausal women with hypothyroidism …

Most clinicians assume that a thyroid mass which appears to be malignant is most likely a tumour arising from thyroid cells. We present a case where the thyroid malignancy was associated with a degree of systemic clinical and biochemical disturbance which suggested alternative diagnoses, and in which fine-needle aspiration revealed that the patient had a thyroid lymphoma …

OBJECTIVE: In the last few years a number of studies have found that metformin has a thyrotropin (TSH)-lowering effect in patients with type 2 diabetes (DM2) and that this effect disappears after discontinuation of the drug. Initial studies were carried out in hypothyroid patients on levothyroxine (LT4) treatment …

OBJECTIVE: Zinc is essential for many biochemical processes and also for cell proliferation. Thyroid hormones influence zinc metabolism by affecting zinc absorption and excretion. Additionally, zinc deficiency affects thyroid function. The aim of the present study was to evaluate a possible association of zinc levels with thyroid volume …

Albania is an in-transition country in the Balkan area and among those with the lowest per capita income in Europe. The Health System of Albania, as the Albanian society itself, is now taking its first steps in adopting the Western financial model. Globalization in modern Western society, even at the level of dietary practices …

Distant metastases as initial presentation of follicular carcinoma of the thyroid is rare, especially in young patients. We report the clinical and pathological features of a 33-year old pregnant patient with follicular carcinoma of the thyroid who presented with widespread bone and lung metastases at the time of diagnosis…
