ABSTRACT
ABSTRACT Objective: The objective of the study was to determine how physicians in Brazil manage Graves' disease in different scenarios including extrathyroidal manifestations. Materials and methods: This study was conducted via a digital survey. The respondents (n = 573) answered multiple-choice questions based on a clinical case and variations of the case regarding laboratory and imaging evaluation, treatment choice, and follow-up. Results: The preferred initial treatment chosen by 95% of the respondents was ATD with a preferred treatment duration of 18-24 months. For 5% of the respondents, RAI was the initial treatment of choice. None of the respondents chose thyroidectomy. When presented with a patient with a desire for pregnancy in the near future, most respondents (69%) opted for ATD as the initial treatment. For a patient with signs of mild to moderate Graves' orbitopathy, ATD remained the initial therapy for 93.9% of the respondents. For patients initially treated with ATD with disease recurrence after ATD interruption, most respondents (60%) chose definitive treatment with RAI. A similar survey published in 2011 by Burch and cols. had results comparable to those of the present survey but with a higher proportion of respondents choosing RAI (45% in the 2011 survey versus 5% in the present survey). Conclusion: Brazilian endocrinologists choose ATD as the initial management of Graves' disease, and most choose RAI as a definitive treatment for a patient with relapse after ATD therapy.
ABSTRACT
ABSTRACT Objective: Choosing Wisely (CW) is an initiative that aims to advance the dialogue between physicians and patients about low-value health interventions. Given that thyroid conditions are frequent in clinical practice, we aimed to develop an evidence-based list of thyroid CW recommendations. Materials and methods: The Thyroid Department of the Brazilian Society of Endocrinology and Metabolism (SBEM) named a Task Force to conduct the initiative. The Task Force work was based on an electronic Delphi approach. The 10 recommendations that received the highest scores by the Task Force were submitted for voting by all SBEM associates. The 5 recommendations that received the highest scores by SBEM associates are presented herein. Results: The Task Force was composed of 14 thyroidologists from 10 tertiary-care, teaching-based Brazilian institutions. The brainstorming/ideation phase resulted in 69 recommendations. After the removal of duplicates and recommendations that did not adhere to the initiative's scope, 35 remained. Then the Task Force voted to attribute a grade (0 [lowest agreement] to 10 [highest agreement]) for each recommendation. The 10 recommendations that received the highest scores by the Task Force were submitted to all SBEM associates. A total of 683 associates voted electronically, attributing a grade (0 to 10) for each recommendation. The 5 recommendations that received the highest scores by the SBEM associates compose our final list. Conclusion: A set of recommendations to avoid unnecessary medical tests, treatments, or procedures for thyroid conditions are offered with a transparent methodology. This initiative aims to foster productive interactions between physicians and patients, stimulating shared decision-making.

Objective The objective of this study was to evaluate the efficacy and safety of percutaneous ethanol injection (PEI) in the treatment of benign thyroid nodules. Subjects and methods We evaluated 120 patients with benign thyroid nodules. Patients underwent evaluation of serum TSH and free T4, cervical ultrasound, and thyroid scintigraphy (in those with suppressed TSH levels). The application of sterile ethanol 99% was guided by ultrasound, with the injected volume amounting to one-third of the nodule volume. Response was considered complete (reduction of 90%); partial (reduction between 50 and 90%); or none (reduction of < 50%). Autonomous nodules were evaluated for normalization of TSH levels. Results Among the nodules studied, 30.8% were solid, 56.7% were mixed, 12.5% were cystic, and 21.6% were hyperfunctioning. The initial volume of the treated nodules ranged from 0.9 to 74.8 mL (mean 13.1 ± 12.4 mL). We performed 1-8 sessions of PEI, applying an average of 6.2 mL of ethanol for patient. After 2 years of follow-up, 17% of patients achieved a complete response (94% reduction); 53%, a partial response (70% reduction); and 30%, no response. A reduction in the volume of autonomous nodules was noted in 70% of cases, and 54% had a normalized value of TSH. The main side effect is local pain, lasting less than 24 hours in most cases. Conclusion This study showed that PEI is a safe and effective procedure for treatment of benign, solid or mixed thyroid nodules. Most cases resulted in significant reduction in nodule volume, with normalization of thyroid function. Arq Bras Endocrinol Metab. 2014;58(9):912-7 .
Objetivo O objetivo deste estudo foi avaliar a eficácia e segurança da injeção percutânea de etanol (IPE) no tratamento de nódulos tireoidianos benignos. Sujeitos e métodos Foram avaliados 120 pacientes com nódulos benignos de tireoide. Todos realizaram dosagens de TSH, T4 livre, ecografia cervical (US) e cintilografia de tireoide (em pacientes com TSH suprimido). A aplicação de etanol estéril a 99% foi guiada por US e o volume de etanol injetado correspondeu a um terço do volume nodular calculado. A resposta foi considerada completa (redução de 90%); parcial (redução entre 50 e 90%) ou ausência de resposta (redução menor que 50%). Nos nódulos autônomos, foi avaliada a normalização do TSH. Resultados Entre os nódulos estudados, 30,8% eram sólidos, 56,7% eram mistos, 12,5% eram císticos e 21,6%, nódulos hiperfuncionantes. O volume inicial dos nódulos tratados variou de 0,9 a 74,8 mL (média 13,1 ± 12,4 mL). Foram realizadas de 1 a 8 sessões de IPE (média 2,8), com aplicação média de 6,2 mL de etanol por paciente. Após dois anos de seguimento, 17% dos pacientes obtiveram resposta completa (redução de 94%), 53% obtiveram resposta parcial (redução de 70%) e 30% não responderam. Houve redução de volume nos nódulos autônomos em 70% dos casos, e 54% normalizaram o valor do TSH. Os efeitos colaterais registrados foram decorrentes apenas do desconforto no local de aplicação. Conclusão Este trabalho mostrou que a IPE é um procedimento seguro e eficaz para tratamento de nódulos benignos, sólidos ou mistos de tireoide. ...
