Selective case finding versus universal screening for detecting hypothyroidism ...
Berbara,Tatiana Martins Benvenuto Louro; Morais,Nathalie Silva de; Saraiva,Débora Ayres; Corcino,Carolina Martins; Schtscherbyna,AnnieABSTRACT Objective Maternal hypothyroidism during pregnancy may lead to adverse outcomes. Recently published guidelines by the American Thyroid Association (ATA) do not advocate for universal screening but recommend a case-finding approach in high-risk pregnant women. The present study aims to evaluate the accuracy of this approach in identifying women with thyroid dysfunction during early pregnancy. Subjects a...
Thyroid nodules ≤ 1 cm and papillary thyroid microcarcinomas: Brazilian experts...
Rosario,Pedro Weslley; Ward,Laura Sterian; Graf,Hans; Vaisman,Fernanda; Mourão,Gabriela Franco; Vaisman,MarioABSTRACT The indolent evolution of low-risk papillary thyroid microcarcinoma (mPTC) in adult patients and the consequences of thyroidectomy require a revision of the management traditionally recommended. Aiming to spare patients unnecessary procedures and therapies and to optimize the health system in Brazil, we suggest some measures. Fine-needle aspiration of nodules ≤ 1 cm without extrathyroidal extension on ...
Recent recommendations from ATA guidelines to define the upper reference range ...
Morais,Nathalie Anne de Oliveira e Silva de; Assis,Annie Schtscherbyna Almeida de; Corcino,Carolina Martins; Saraiva,Débora AyresABSTRACT Objectives: American Thyroid Association (ATA)'s new guidelines recommend use of population-based trimester-specific reference range (RR) for thyrotropin (TSH) in pregnancy. The aim of this study was to determine first trimester TSH RR for a population of pregnant women in Rio de Janeiro State. Subjects and methods: Two hundred and seventy pregnant women without thyroid illness, defined by National Aca...
Heart rate response to graded exercise test of elderly subjects in different ra...
Carvalho,Rafael Cavalcante; Vigário,Patrícia dos Santos; Chachamovitz,Dhiãnah Santini de Oliveira; Silvestre,Diego Henrique da SilvaABSTRACT Objective: Life expectancy is increasing worldwide and studies have been demonstrating that elevated serum thyroid stimulating hormone (TSH) concentration in elderly is associated with some better health outcomes. This elevation is somewhat physiological as aging. The aim of this study was to investigate the heart rate (HR) response during a graded exercise test and its recovery in healthy elderly, com...

Barbosa,Mayara Peres; Momesso,Denise; Bulzico,Daniel Alves; Farias,Terence; Dias,Fernando; Lima,Roberto Araújo; Corbo,Rossana; Vaisman,MarioABSTRACT Objective: The aim of this study was to evaluate the association between this characteristic and outcomes in patients with lymph node metastasis in a Brazilian cohort. Subjects and methods: This study examined a retrospective cohort of adult patients diagnosed with differentiated thyroid cancer and lymph node metastases from 1998 to 2015 in two referral centers. Number, location, size and extranodal ex...

Souza,Marcelo Cruzick de; Momesso,Denise P.; Vaisman,Fernanda; Vieira Neto,Leonardo; Martins,Rosangela Aparecida Gomes; Corbo,Rossana; Vaisman,MarioObjective Much controversy relates to the risk of non-synchronous second primary malignancies (NSSPM) after radioactive iodine treatment (RAI-131) in differentiated thyroid cancer (DTC) patients. This study evaluated the relationship between RAI-131 and NSSPM in DTC survivors with long-term follow-up. Materials and methods Retrospective analysis of 413 DTC cases was performed; 252 received RAI-131 and 161 were ...

Souza,Luciana Lopes de; Guedes,Erika Paniago; Teixeira,Patrícia Fátima dos Santos; Moreira,Rodrigo Oliveira; Godoy-Matos,Amelio Fernando; Vaisman,MarioAbstract Objective: To investigate the relationship between serum thyrotropin (TSH), insulin resistance (IR), and cardiovascular risk factors (CRF) in a sample of overweight and obese Brazilian adolescents. Methods: A retrospective, longitudinal analysis of 199 overweight and obese pubescent adolescents was performed. The TSH and free T4 (fT4) levels, anthropometric measurements, and laboratory test results of ...

Araujo,Débora Batista; Barone,Bianca; Melleti,Natasha Ferreira Teixeira; Dantas,Joana Rodrigues; Oliveira,Marcus Miranda dos Santos; Zajdenverg,LenitaObjective Thyroid diseases are common in individuals with type 1 diabetes mellitus (T1DM) and should be investigated annually in these individuals. The aim of this study was to evaluate the frequency of thyroid diseases in first degree relatives (FDR) of patients with T1DM. Subjects and methods Eighty individuals (40 patients with T1DM and 40 FDR) were interviewed and blood was sampled for thyroid-stimulating h...
Estimates of thyroid cancer incidence in Brazil: an approach using polynomial m...
Brito,Alexandre dos Santos; Coeli,Cláudia Medina; Barbosa,Flávia dos Santos; Caetano,Rosangela; Santos,Marceli de Oliveira; Vaisman,MarioThis study aimed to estimate thyroid cancer incidence in Brazil in 2006 using polynomial models that take age and birth cohort effects into account in the estimation process. Estimates were based on new cases of thyroid cancer in nine Brazilian cities (Manaus, Palmas, Natal, Recife, Cuiabá, Belo Horizonte, São Paulo, Porto Alegre, and Curitiba) and the Federal District from 1997 to 2001. We estimated 6,066 new ...

Tavares,Ana Beatriz Winter; Paula,Simone Kalil de; Vaisman,Mario; Teixeira,Patrícia de Fátima dos SantosRelata-se que a disfunção tireoidiana induzida pela amiodarona afeta de 2 a 24% dos usuários. Embora seja fácil tratar o hipotireoidismo induzido pela amiodarona, o desenvolvimento da tireotoxicose leva a uma abordagem difícil na maioria dos casos. O objetivo deste estudo é descrever três casos diferentes de pacientes com tireotoxicose induzida por amiodarona e discutir os aspectos clínicos e laboratoriais, e a...
