1. Thyroid gland changes in patients with acromegaly
ABSTRACT Objective Acromegaly is characterized by high neoplastic morbidity as a side effect of growth hormone (GH) hypersecretion. Increased incidence of goiter, thyroid carcinoma, and thyroid dysfunction is also reported. The aim of the present study was to find the prevalence of thyroid dysfunction and goiter in patients with acromegaly and determine it

2. Timing of thyroid ultrasonography in the etiological investigation of congenital hypothyroidism
ABSTRACT Objectives To describe the findings of thyroid ultrasonography (T-US), its contribution to diagnose congenital hypothyroidism (CH) and the best time to perform it. Subjects and methods Forty-four patients with CH were invited to undergo T-US and 41 accepted. Age ranged from 2 months to 45 years; 23 patients were females. All were treated with L-

3. Ultrasonographic assessment of thyroid volume in oldest-old individuals
ABSTRACT Objective The aim of this study was to describe the relationship between thyroid volume and age, gender, anthropometric characteristics, and echogenicity in oldest-old subjects in an iodine-sufficient area. Subjects and methods The study included 81 independent elderly individuals aged ≥ 80 years (65 [80.2%] women). We determined these individ

4. Coexistence of resistance to thyroid hormone and ectopic thyroid: ten-year follow-up
SUMMARY Resistance to thyroid hormone (RTH) coexisting with ectopic thyroid is rare. Here we report a case of RTH with ectopic thyroid. A ten-year-old girl had been misdiagnosed as congenital hypothyroidism and treated with levothyroxine since she was born. Ten-year follow-up showed that the elevated thyrotropin was never suppressed by levothyroxine and no s

5. FT3/FT4 ratio predicts non-alcoholic fatty liver disease independent of metabolic parameters in patients with euthyroidism and hypothyroidism
OBJECTIVE: This study was performed to evaluate the effects of metabolic parameters and thyroid dysfunction on the development of non-alcoholic fatty liver disease (NAFLD). METHODS: The current study evaluated a total of 115 patients, 75 female and 40 male. Physical examination and anthropometric measurements were applied to all participants. Hypothyroidis

6. Circulating levels of irisin is elevated in hypothyroidism, a case-control study
Objective Our objective in this study was to determine the relationship between irisin hormone, which has a similar effect with thyroid hormones on adipose tissue and the metabolism, and the thyroid functions and the obesity secondary to thyroid disease. Subjects and methods Seventy-four patients were included in the study, of the patients, 37 were newly

7. Thyroid function, autoimmunity and nodules in hematological malignancies
Objective Hematological malignancies encompass a large spectrum of disease entities whose treatment by chemo/radiotherapy could lead to thyroid complications. To the best of our knowledge, no study has simultaneously addressed thyroid function, autoimmunity and nodularity. Therefore, we decided to conduct one.Materials and methods We evaluated 82 Caucasian p

8. The role of the resistive index in Hashimoto's thyroiditis: a Sonographic pilot study in children
OBJECTIVE: The role of Doppler ultrasonography in the diagnosis of diffuse thyroid diseases is not well established. In particular, Doppler ultrasonography findings in children with Hashimoto's thyroiditis are very limited. We examined gray-scale and Doppler ultrasound findings in Hashimoto's thyroiditis in children in an attempt to understand the feasibilit

9. Thyroid hormonal disturbances related to treatment of hepatitis C with interferon-alpha and ribavirin
OBJECTIVE: To characterize thyroid disturbances induced by interferon-alpha and ribavirin therapy in patients with chronic hepatitis C. INTRODUCTION: Interferon-alpha is used to treat chronic hepatitis C infections. This compound commonly induces both autoimmune and non-autoimmune thyroiditis. METHODS: We prospectively selected 26 patients with chronic hepat

10. Mapeamento dúplex-Doppler colorido na avaliação da eficácia do Laser de baixa intensidade para o tratamento da tireoidite crônica autoimune: ensaio clínico randomizado placebo-controlado / Color Doppler ultrasonography in the evaluation of efficacy of the low-intensity Laser therapy of chronic autoimmune thyroiditis: placebo-controlled randomized clinical trial
INTRODUÇÂO: A tireoidite crônica autoimune (TCA) é a principal causa de hipotireoidismo adquirido, o qual requer tratamento contínuo com levotiroxina (LT4). Até o momento, não há terapia capaz de regenerar o tecido tireóideo lesado e melhorar sua função. Como a terapia com Laser de baixa intensidade (LILT) foi eficaz em outras doenças autoimunes,

11. Subclinical thyroid function and thyroid ultrasound characteristics in a sample of women submitted to screening of thyroid function at worksite / Função tireoidiana subclínica e aspectos ultra-sonográficos em mulheres submetidas a rastreamento de função tireoideana em local de trabalho
INTRODUÇÃO: No Brasil, são poucos os estudos sobre a freqüência das doenças tireoidianas e a maioria limita-se a populações específicas. OBJETIVOS: O objetivo principal deste estudo é correlacionar função tireoidiana subclínica a aspectos ultra-sonográficos em mulheres que realizaram rastreamento para função tireoidiana em local de trabalho.

12. Familial congenital hypothyroidism due to inactivating mutation of the thyrotropin receptor causing profound hypoplasia of the thyroid gland.
Thyroid gland agenesis is the most common cause of congenital hypothyroidism and is usually sporadic. We investigated a brother and sister from consanguineous parents, ascertained through systematic newborn screening, and initially diagnosed with thyroid agenesis. Careful cervical ultrasonography in both patients revealed a very hypoplastic thyroid gland. By
