Evaluación de la agudeza diagnóstica de la Ecografía Translaríngea Transcutánea (ETLTC) en la valoración de la movilidad de las cuerdas vocales en cirugía de tiroides y paratiroides / Evaluation of the diagnostic acuity of the Transcutaneous Translaryngeal Ultrasound (TCTLUS) in the assessment of the vocal cords mobility in thyroid and parathyroid surgery

Introducción. La evaluación de la movilidad de las cuerdas vocales en cirugía de tiroides y paratiroides hace parte de la adecuada valoración integral. Aunque la laringoscopia directa es prueba de referencia, su uso real no es rutinario por lo que se propone la ecografía translaríngea como alternativa de evaluación. Métodos. Estudio prospectivo de evaluación de una prueba diagnóstica de la movilidad de las cuerdas vocales pre y posoperatoria, comparando la ecografía translaríngea con la video laringoscopia, en pacientes con cirugía de tiroides y paratiroides, de febrero 1° a noviembre 30 de 2022. Se describieron las variables usando frecuencias absolutas y relativas. En el análisis univariado se calcularon Chi cuadrado y T de Student y en el bivariado, regresión logística binaria. La agudeza diagnóstica se determinó con sensibilidad, especificidad y valores predictivos; se consideró la significancia estadística con p < 0,05. Resultados. Se incluyeron 267 pacientes, 219 mujeres y 48 hombres; 196 pacientes (73,4%) tenían malignidad. Se encontró en el preoperatorio, sensibilidad 100 %, especificidad 99,6 %, VPP 83,3 %, VPN 100 %, odds de probabilidad positiva 83 % y Odds de probabilidad negativa 0,004 %. En el posoperatorio, sensibilidad 82,8 %, especificidad 99,2 %, VPP 92,3 % VPN 97,9 %, odds de probabilidad positiva 92 % y odds de probabilidad negativa 0,2 %. Conclusiones. La ecografía translaríngea en nuestro medio tiene alta agudeza diagnóstica. Podría ser usada en el abordaje inicial de la evaluación de la movilidad de las cuerdas vocales y reemplazar la laringoscopia directa, dejando ésta para cuando la visualización ecográfica no sea adecuada, o en casos de afectación o sospecha de invasión, para su confirmación.

Introduction. The evaluation of the mobility of the vocal cords in thyroid and parathyroid surgery is part of the adequate comprehensive assessment. Altough, direct laryngoscopy is the gold standard, its real use is not routine, so translaryngeal ultrasound approach is proposed as an alternative. Methods. A prospective diagnostic test study was carried out to evaluate the translaryngeal ultrasound compared with video laryngoscopy in visualizing vocal mobility in patients with thyroid and parathyroid surgery from February 1 to November 30, 2022. Patients were described using absolute and relative frequencies. Univariate statistical analysis with Chi-square and Student's t tests. T. Bivariate analysis using binary logistic regression. Diagnostic acuity was calculated with sensitivity, specificity, PPV, NPV. Statistical significance with p< 0.05, 95% confidence interval. Results. 267 patients undergoing thyroid or parathyroid surgery were included, 219 women and 48 men. Malignant: thyroid neoplasm 196 patients (73.4%). The findings were for the preoperative period, 100% sensitivity, 99.6% specificity, PPV 83.33%, NPV 100%, 83% positive probability odds, and 0.004% negative probability odds. For the postoperative period, 82.8% sensitivity, 99.2% specificity, 92.3% PPV, 97.9% NPV, 92% positive probability odds, and 0.2% negative probability odds were found.Conclusions. Translaryngeal ultrasound in our series has high diagnostic acuity. It could be used as the initial approach to evaluate vocal mobility and might replace direct laryngoscopy, leaving it when its visualization is not adequate or in cases of involvement or suspected invasion for confirmation.

Manejo del paciente con Hipertiroidismo en consulta externa de la Unidad Técnica de Endocrinología del Hospital Carlos Andrade Marín / Management of the patient with hyperthyroidism in the outpatient clinic of the Technical Unit of Endocrinology of the Endocrinology Technical Unit of the Carlos Andrade Marín Hospital

El hipertiroidismo es un trastorno caracterizado por el exceso de hormonas tiroideas. El déficit de yodo es un factor clave en dicha patología y en lugares con suficiencia del mismo se asocian a au-toinmunidad tiroidea. La prevalencia de hipertiroidismo mani-fiesto varía del 0,2% al 1,3% en áreas con suficiencia de yodo, sin embargo, esto puede variar en cada país por diferencias en umbrales de diagnóstico, sensibilidad de ensayo y población se-leccionada. Un reporte de The Third National Health and Nutri-tion Examination Survey (NHANES III) mostró que el hiperti-roidismo manifiesto se presenta en 0,7% de la población general e hipertiroidismo subclínico en el 1,7%1,2.En incidencia, la patología se asocia con la suplementación de yodo, con la mayor frecuencia en áreas de deficiencias, por au-mento de nódulos tiroideos en la población anciana, teniendo a regiones de áreas montañosas como América del Sur, África Central y suroeste de Asia dentro de este grupo. Un meta aná-lisis de estudios europeos mostró una incidencia general de 50 casos por 100000 personas/años1. En Ecuador, según los datos del Instituto Nacional de Estadísticas y Censos (INEC) del 2017, se reportaron 157 casos de hipertiroidismo, de los cuales la En-fermedad de Graves (EG) fue la causa más común, seguida por el bocio multinodular tóxico (BMNT) y finalmente el adenoma tóxico (AT) con una incidencia de 61 %, 24 % y 14 % respecti-vamente3.Los pacientes con esta patología tienen aumento de riesgo com-plicaciones cardiovasculares y mortalidad por todas las causas, siendo falla cardíaca uno de sus principales desenlaces, así el diagnóstico precoz evita estos eventos, principalmente en pobla-ción de edad avanzada.El presente protocolo se ha realizado para un correcto trata-miento de esta patología en el Hospital de Especialidades Carlos Andrade Marín (HECAM).

Hyperthyroidism is a disorder characterized by an excess of thyroid hormones. Iodine deficiency is a key factor in this pa-thology and in places with iodine deficiency it is associated with thyroid autoimmunity. The prevalence of overt hyperthyroidism varies from 0,2% to 1,3% in iodine-sufficient areas; however, this may vary from country to country due to differences in diag-nostic thresholds, assay sensitivity, and selected population. A report from The Third National Health and Nutrition Examina-tion Survey (NHANES III) showed that overt hyperthyroidism occurs in 0,7% of the general population and subclinical hyper-thyroidism in 1,7%1,2.In incidence, the pathology is associated with iodine supplemen-tation, with the highest frequency in areas of deficiencies, due to increased thyroid nodules in the elderly population, having regions of mountainous areas such as South America, Central Africa and Southwest Asia within this group. A meta-analysis of European studies showed an overall incidence of 50 cases per 100000 person/years1. In Ecuador, according to data from the National Institute of Statistics and Census (INEC) in 2017, 157 cases of hyperthyroidism were reported, of which, Graves' di-sease (GD) was the most common cause, followed by toxic mul-tinodular goiter (BMNT) and finally toxic adenoma (TA) with an incidence of 61 %, 24 % and 14 % respectively3.Patients with this pathology have an increased risk of cardiovas-cular complications and all-cause mortality, with heart failure being one of the main outcomes, so early diagnosis avoids these events, mainly in the elderly population.The present protocol has been carried out for the correct treat-ment of this pathology at the Carlos Andrade Marín Specialties Hospital (HECAM).

Sintomas vocais, ansiedade e depressão pré e pós-tireoidectomia / Vocal symptoms, anxiety and depression pre and post thyroidectomy / Síntomas vocales, ansiedad y depresión pre y post tiroidectomía

Introdução: Alterações na tireoide e a tireoidectomia podem levar à sintomatologia vocal e emocional.Objetivo: Correlacionar sintomas vocais e traços de ansiedade e depressão pré e pós-tireoidectomia. Métodos: Estudo observacional, longitudinal. Participaram 20 pacientes submetidos à tireoidectomia, ao exame visual laríngeo e à Escala de Sintomas Vocais (ESV) e Escala Hospitalar de Ansiedade e Depressão (HADS) no pré-operatório, pós 1 semana e pós 3 meses, com média de idade de 54,5 anos, maior prevalência do sexo feminino (85%) e tireoidectomia parcial (70%). Resultados: Os pacientes autorreferiram sintomas vocais em todos os momentos, com maior frequência após uma semana e diferença significativa entre o domínio físico pré e pós 1 semana. Na HADS, observou-se maior escore total no pré-operatório e diferença significante nos três momentos, em todos os domínios, com maior diferença entre pré e pós 1 semana. Houve correlação positiva fraca entre os domínios limitação, emocional e escore total da ESV com a subescala de ansiedade pós 1 semana, entre o escore total da ESV e o escore total da HADS e correlação positiva moderada entre os domínios limitação e emocional da ESV com o escore total da HADS após uma semana. Conclusão: Pacientes submetidos à tireoidectomia autopercebem sintomas vocais e traços de grau leve de ansiedade tanto no pré quanto pós 1 semana e após 3 meses de cirurgia com pior autorreferência após uma semana. Quanto maior a autorreferência de sintomas vocais, mais traços de ansiedade o paciente pode apresentar. (AU)

Introduction: Thyroid alterations and thyroidectomy can lead to vocal and emotional symptoms.Purpose: To correlate vocal symptoms and anxiety and depression traits pre and post-thyroidectomy. Methods: Observational, longitudinal study. Participants were 20 patients who underwent thyroidectomy, laryngeal visual examination and the Voice Symptom Scale (VoiSS) and Hospital Anxiety and Depression Scale (HADS) preoperatively, 1 week and 3 months after, with a mean age of 54.5 years, higher prevalence of female gender (85%) and partial thyroidectomy (70%). Results: The patients self-reported vocal symptoms at all times, more frequently after one week and a significant difference between the physical domain pre and post 1 week. In HADS, there was a higher total score in the preoperative period and a significant difference in the three moments, in all domains, with a greater difference between pre and post 1 week. There was a weak positive correlation between the limitation, emotional and total score of the ESV domains with the anxiety subscale after 1 week, between the total score of the ESV and the total score of the HADS, and a moderate positive correlation between the limitation and emotional domains of the ESV with the HADS total score after one week. Conclusion: Patients undergoing thyroidectomy self-perceived vocal symptoms and mild anxiety traits both before and after 1 week and after 3 months of surgery with worse self-report after one week. The greater the self-report of vocal symptoms, the more traces of anxiety the patient may present. (AU)

Introducción: Cambios en la tiroides y tiroidectomía pueden provocar síntomas vocales y emocionales. Objetivo: Correlacionar síntomas vocales y rasgos de ansiedad y depresión antes y después de tiroidectomía. Metodos: Estudio observacional/longitudinal. Participaron 20 pacientes que se les realizó tiroidectomía, examen visual laríngeo, Escala de Síntomas Vocales (ESV) y Escala Hospitalaria de Ansiedad y Depresión (HADS) en preoperatorio, 1 semana y 3 meses después, con edad media de 54,5 años, prevalencia del género femenino (85%) y tiroidectomía parcial (70%). Resultados: Los pacientes informaron síntomas vocales en todo momento, con mayor frecuencia después de una semana y una diferencia significativa entre el dominio físico antes y después de 1 semana. En HADS, hubo mayor puntaje total en el preoperatorio y diferencia significativa en los tres momentos, con mayor diferencia entre pre y post 1 semana. Hubo una correlación positiva débil entre limitación, emocional y total de los dominios de la ESV con la subescala de ansiedad después de 1 semana, entre el total de la ESV y e total de la HADS, y una correlación positiva moderada entre la puntuación de limitación y dominios emocionales de la ESV con la puntuación total de HADS después de una semana. Conclusión: Los pacientes sometidos a tiroidectomía autopercibieron síntomas vocales y rasgos de ansiedad leve tanto antes como después de 1 semana y después de 3 meses de la cirugía con peor autoinforme después de una semana. Cuanto mayor es el autoinforme de síntomas vocales, más rastros de ansiedad puede presentar el paciente. (AU)

Enfermedad de cambios mínimos cortico-resistente e hipotiroidismo. Reporte de caso / Steroid-resistant minimal change disease and hypothyroidism: Case report

Introducción: La enfermedad de cambios mínimos es una causa rara de síndrome nefrótico en el adulto, y su relación con el hipotiroidismo es más rara aún. Se considera que esta patología renal responde favorablemente al manejo con glucocorticoides y tiene una baja frecuencia de resistencia. Su abordaje hoy en día es objeto de investigación. Objetivo: Describir una rara etiología de síndrome nefrótico en el adulto con presentación, tratamiento y desenlace infrecuentes. Presentación del caso: Paciente femenino de 53 años quien inicia con síndrome nefrótico por enfermedad de cambios mínimos cortico-resistente y su asociación con un hipotiroidismo descontrolado, quien requiere manejo con rituximab y control de la enfermedad endocrinológica asociada, como enfermedad de base. Conclusiones: En este caso clínico se muestra como las enfermedades citadas pueden coexistir y el tratamiento en conjunto es necesario. El establecimiento de nuevas terapias en la población adulta como el rituximab podría mostrar beneficio, como en este caso. Sin embargo, aún existe la necesidad de estudios de mayor evidencia que validen firmemente la efectividad de los diferentes tratamientos en este tipo de pacientes.

Introduction: Minimal change disease is a rare cause of nephrotic syndrome in adults, and its association with hypothyroidism is even more exceptional. This renal pathology is considered to respond favorably to glucocorticoid management and has a low resistance frequency. How to approach this disease is currently under investigation. Objective: To describe a rare etiology of adult nephrotic syndrome with unusual presentation, treatment, and outcome. Case presentation: A 53 years-old female patient who initially experienced nephrotic syndrome due to steroid-resistant minimal change disease, which was also associated with uncontrolled hypothyroidism. She required management with rituximab and control of the associated endocrinological disease, which was considered as the underlying disease. Conclusions: This clinical case shows (i) how the two aforementioned diseases can coexist and (ii) that a joint treatment is necessary. Establishing new therapies may be beneficial for adult populations, such as the benefits seen in this case with the use of rituximab. However, further studies are needed to strongly validate the effectiveness of the different treatments for these types of patients.

Factores clínicos y ambientales asociados a la tiroiditis de Hashimoto / Clinical and environmental factors associated with Hashimoto's thyroiditis

Introducción: La tiroiditis de Hashimoto es una enfermedad tiroidea autoinmune poligénica y multifactorial resultante de una interacción compleja de factores genéticos y ambientales. Objetivo: Determinar la posible asociación de los factores clínicos y ambientales con los niveles de anticuerpos antitiroideos y las pruebas de función tiroidea en la tiroiditis de Hashimoto. Métodos: Estudio observacional, descriptivo y transversal con 120 personas con diagnóstico de tiroiditis de Hashimoto. Variables estudiadas: edad, sexo, color de la piel, estado nutricional, paridad, hábito de fumar, consumo de alcohol, preparados estrogénicos, antecedentes familiares de enfermedad autoinmune tiroidea y personales de otras enfermedades autoinmunes.

Twenty percent had family history of thyroid disease and personal history of type 1 diabetes mellitus (7.5 percent). The mean antibody in patients with history of viral infections was higher than those without this history (732.6 vs. 624.6). The rest of the variables did not show differences between the means of the antibody. None of the factors studied showed association with the state of thyroid function. (p > 0.05). Conclusions: There was no association between clinical and environmental factors in relation to Ac TPO levels and the state of thyroid function, with a predominance of overt hypothyroidism at diagnosis of HT(AU)

Frequency of oral Lichen Planus among hypothyroid patients / Frequência de Líquen Plano oral em pacientes com hipotireoidismo

Objective: Recent investigations have suggested a correlation between thyroid diseases, particularly hypothyroidism (HT), and oral lichen planus (OLP). Objective: This study aimed to assess the frequency of OLP in HT patients. Material and Methods: This analytical descriptive study evaluated 100 HT patients including 94 females and 6 males, who were selected by convenience sampling. The subjects were clinically examined for OLP. The mean age of patients was 42.49±1.29 years. Also, 100 age- and sex-matched healthy controls were examined. The data were analyzed using chi-square test and Fisher's exact test via SPSS. Results: Of all, 14 (14%) HT patients (12 females and 2 males) had OLP while only one case of OLP was found in the control group. The difference between the two groups in the frequency of OLP was significant (P=0.001). The odds ratio (OR) of developing OLP was calculated to be 16.11 in HT patients. Reticular form was the most common type of OLP in patients (50%). The buccal mucosa was the most common site of involvement (92.85%). The mean age of patients with OLP was 42.93±1.29 years with a median of 46±1.29 years in HT group. Conclusion: The frequency of OLP was significantly higher in HT patients such that HT patients had higher odds of developing OLP by 16 folds. (AU)

Assessment of thyroid disorders in patients with rosacea: a large case-control study

Abstract Background: The frequency of autoimmune diseases and thyroid cancer has been increasingly reported in association with rosacea. However, studies investigating thyroid diseases in rosacea are scarce with conflicting results. Objective: To investigate the relationship between thyroid disorders and rosacea. Methods: A large case-control study on ageand gender-matched 2091 rosacea patients and 9572 controls was conducted. Rosacea patients using the rosacea-specific ICD codes were compiled from the hospital records. Additionally, all participants were evaluated in terms of the presence of hypothyroidism and hyperthyroidism. Conditional logistic regression analysis was used to compute case-control odds ratios (OR) with 95% confidence intervals. Results: The analysis comprehended 2091 rosacea patients (1546 female, 545 male; mean 48.73 ± 14.53 years) and 9572 controls (7009 female, 2563 male; mean 48.73 ± 15.1 years). Whereas the rate of hypothyroidism was significantly higher in rosacea patients (OR = 1.3, 95% CI 1.13-1.49, p < 0.001), there was no significant difference in the rate of hyperthyroidism between the groups (OR = 1.12, 95% CI 0.81-1.53, p = 0.497). Stratification for gender revealed a significant association between hypothyroidism and rosacea in females (OR = 1.27, 95% CI 1.1-1.47, p = 0.002) and males (OR = 1.58, 95% CI 1.04-2.4, p = 0.032). The frequency of hypothyroidism in rosacea patients increased towards the age range of 40-49 and then decreased, parallel with the hypothyroidism frequency of the study population. Study limitations: Different subtypes and severities of rosacea were not distinguished. Conclusions: Hypothyroidism may be a comorbidity of rosacea and investigation for hypothyroidism may be appropriate when evaluating rosacea patients.

Potential targets for the hepatitis C virus-mediated autoimmune thyroiditis

2021.174934ABSTRACTIntroduction: The mechanisms by which hepatitis C virus (HCV) infection induces autoimmune thyroiditis (AIT) have been studied, and it was suggested that inflammatory cytokines during HCV infection would change the thy-roperoxidase (TPO) signaling cascade and thyroglobulin (Tg) determining autoimmune thyroid disease.Objective: To show the signaling pathway, of TPO and Tg, and their potential targets mediated HCV in individuals with hepatitis C.Methods: The mapping of the signaling pathway was based on a review study approach and performed using the automatic annotation server of the Kyoto and Genome Encyclopedia (KEGG). PathVisio is free software for analysis and design of open source routes, and was used for the graphic representation of the signaling pathway.Results: The contigs were extracted from the KEGG database and their mapped transcription represents the signa-ling pathway of the main biomolecules that triggers the AIT. The action of HCV, or its treatment can trigger AIT that is characterized by the presence of autoantibodies against TPO and Tg. In AIT, autoreactive CD4 + T lymphocytes recruit B cells and CD8 + T cells in the thyroid. The progression of the disease leads to the death of thyroid cells and hypothyroidism. Conclusion: HCV or its treatment activates several signaling pathways with thyroid cells damage resulting in AIT and secondary hypothyroidism to cellular apoptosis. (AU)

RESUMOIntrodução: Os mecanismos pelos quais a infecção com o vírus da hepatite C (HCV) induz à tireoidite autoimune (TAI) têm sido alvo de estudos. Tem sido sugerido que citocinas inflamatórias, como a elevação das interleucinas na inflamação causadas pelo HCV, alterariam a cascata de sinalização da tireoperoxidase (TPO) e tireoglobulina (Tg) determinando um quadro de doença autoimune da tireóide.Objetivo: Demonstrar a via de sinalização da TPO e da Tg e seus potenciais alvos para a TAI mediados pelo HCV em indivíduos com hepatite C.Método: O mapeamento da via de sinalização foi realizado usando o servidor de anotação automática da Enciclopé-dia Quioto de Genes e Genomas (KEGG). O PathVisio, um software gratuito de análise e desenho de vias de código aberto, foi utilizado para a representação gráfica da via de sinalização.Resultado: As sequências foram retiradas do banco de dados KEGG e sua transcrição mapeada representa a via de . sinalização das principais biomoléculas que desencadeia a TAI. A ação do HCV, ou seu tratamento pode desen-cadear a TAI que é caracterizada pela presença de autoanticorpos contra a TPO e Tg. Na TAI os linfócitos T CD4+ auto-reativos recrutam células B e células T CD8+ na tireóide. A progressão da doença leva à morte de células da tireóide e hipotireoidismo.Conclusão: O HCV ou o seu tratamento ativa várias vias de sinalização com dano na célula tireoidiana, tendo como resultado TAI e hipotireoidismo secundário a apoptose celular.

A trial for improving thyroid gland dysfunction in rats by using a marine organism extract / Tentativa para melhorar a disfunção da glândula tireoide em ratos usando um extrato de organismo marinho

Abstract Understanding the relation between the environmental stress factors and the hypothalamus-pituitary-thyroid (HPT) axis efficiency can reduce the susceptibility to thyroid diseases. In our study, thyroid dysfunction was induced in female rats by administration of 40 mg Na F/kg.bd.wt/day for a month. Co-administration of the water extract of Arca noae (300 mg/kg. bw) was tested as a treatment for Na F induced thyroid dysfunction. A group of rats injected Arca noae extract only (300 mg/kg.bd.wt) was performed to observe the impact of the extract on the (HPT) axis in addition to the normal control group. Results showed that there was a significant decrease in serum triglycerides, total protein and albumin levels in the fluoride supplemented group in addition to abnormal levels of TSH, (T4) and (T3) compared to the control group. In the treated group there was an improvement in the proteins level and lipid profile but pseudo-corrected serum (T4) and (T3) levels were observed in addition to a continuous increase in TSH level. Histological findings confirmed the harmful effect of fluoride on both the non treated and the treated groups. Consequently, fluoride supplementation must be considered as a harmful stress that may affect permanently the HPT axis.

Resumo Compreender a relação entre os fatores de estresse ambiental e o eixo hipotálamo-hipófise-tireoide (HPT) pode reduzir a suscetibilidade a doenças da tireoide. Em nosso estudo, a disfunção tireoidiana foi induzida em ratos fêmeas pela administração de 40 mg Na F/kg.bw/dia durante um mês. A administração concomitante do extrato aquoso de Arca noae (300 mg/kg.Pc) foi testada como tratamento para a disfunção tireoidiana induzida por Na F. Um grupo de ratos injetados apenas com extrato de Arca noae (300 mg/kg. Pc) foi pré-formado com o intuito de observar o impacto do extrato no eixo (HPT), além do grupo controle normal. Os resultados mostraram que houve uma diminuição significativa nos níveis séricos de triglicerídeos, proteína total e albumina no grupo suplementado com fluoreto, além de níveis anormais de TSH, (T4) e (T3) em comparação ao grupo controle. No grupo tratado, houve uma melhora no nível de proteínas e perfil lipídico. Os níveis séricos pseudocorrigidos (T4) e (T3) foram observados, além de um aumento contínuo no nível de TSH. Os achados histológicos confirmaram o efeito prejudicial do flúor nos grupos não tratado e tratado. Consequentemente, a suplementação de flúor é considerada um estresse prejudicial que pode afetar permanentemente o eixo HPT.

Incidence of thyroid diseases: Results from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

ABSTRACT Objective: To evaluate incidence of subclinical and overt hyperthyroidism and hypothyroidism. Subjects and methods: The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) is a prospective cohort study of 15,105 civil servants, examined at baseline and over a 4-year follow-up. This analysis included 9,705 participants with normal thyroid function at baseline, follow-up information about thyroid function and with no report of using drugs that may interfere in the thyroid function. Thyroid function was defined by TSH/FT4 levels or routine use of thyroid hormones/anti-thyroid medications. Annual and cumulative (over 4-year) incidence rates were presented as percentages (95% Confidence Intervals). Results: The incidence of all overt and subclinical thyroid disease was 6.7% (1.73%/year): 0.19% for overt hyperthyroidism (0.048%/year), 0.54% for subclinical hyperthyroidism (0.14%/year), 1.98% for overt hypothyroidism (0.51%/year), and 3.99% for subclinical hypothyroidism (1.03%/year). The incidence of all thyroid diseases was higher in women, when compared to men, with a low women:men ratio (1.36). For Blacks the highest incidence was for overt hyperthyroidism, while for Whites, the highest incidence was for overt hypothyroidism. However, the highest incidence of overt hyperthyroidism was detected in Asian descendants. The presence of antithyroperoxidase antibodies at baseline was associated with higher incidence of overt thyroid diseases. Conclusion: These results showed a high incidence of hypothyroidism, which is compatible with a country with a more-than-adequate iodine intake. The low women:men ratio of the incidence of thyroid dysfunction highlights the importance of the diagnosis of thyroid diseases among men in Brazil.

Management of thyroid disorders during the COVID-19 outbreak: a position statement from the Thyroid Department of the Brazilian Society of Endocrinology and Metabolism (SBEM)

ABSTRACT This position statement was prepared to guide endocrinologists on the best approach to managing thyroid disorders during the coronavirus disease (COVID-19) pandemic. The most frequent thyroid hormonal findings in patients with COVID-19, particularly in individuals with severe disease, are similar to those present in the non-thyroidal illness syndrome and require no intervention. Subacute thyroiditis has also been reported during COVID-19 infection. Diagnosis and treatment of hypothyroidism during the COVID-19 pandemic may follow usual practice; however, should avoid frequent laboratory tests in patients with previous controlled disease. Well-controlled hypo and hyperthyroidism are not associated with an increased risk of COVID-19 infection or severity. Newly diagnosed hyperthyroidism during the pandemic should be preferably treated with antithyroid drugs (ATDs), bearing in mind the possibility of rare side effects with these medications, particularly agranulocytosis, which requires immediate intervention. Definitive treatment of hyperthyroidism (radioiodine therapy or surgery) may be considered in those cases that protective protocols can be followed to avoid COVID-19 contamination or once the pandemic is over. In patients with moderate Graves' ophthalmopathy (GO) not at risk of visual loss, glucocorticoids at immunosuppressive doses should be avoided, while in those with severe GO without COVID-19 and at risk of vision loss, intravenous glucocorticoid is the therapeutic choice. Considering that most of the thyroid cancer cases are low risk and associated with an excellent prognosis, surgical procedures could and should be postponed safely during the pandemic period. Additionally, when indicated, radioiodine therapy could also be safely postponed as long as it is possible.

Historia familiar de enfermedad tiroidea y riesgo de hipotiroidismo congénito en neonatos con síndrome de Down / Family history of thyroid disease and risk of congenital hypothyroidism in neonates with Down syndrome

Resumen Introducción: La historia familiar de enfermedad tiroidea (HFET) como factor de riesgo para hipotiroidismo congénito (HC), en síndrome de Down (SD) aún no ha sido explorada. Objetivo: Determinar si la HFET está asociada a mayor riesgo de HC en neonatos con SD. Método: Estudio de casos y controles en 220 neonatos con SD. Se compararon las pruebas de función tiroidea (PFT) de 37 con SD e HFET (casos), frente a las PFT de 183 recién nacidos con SD sin HFET (grupo de referencia). Se realizó análisis de regresión logística multivariante y se calculó la razón de momios (RM) y sus respectivos intervalos de confianza del 95 % (IC 95 %). Resultados: Nueve casos HC (4.1 %). El HC mostró asociación con la HFET (RMa = 8.3, IC 95 %: 2.0-34.3), particularmente en los varones (RMa = 9.0, IC 95 %: 1.6-49.6). La ausencia de HFET tuvo una RM de protección para HC (RMa = 0.4, IC 95 %: 0.1-0.8). Conclusiones: La HFET puede es una estrategia fácil y accesible para identificar pacientes con SD con mayor riesgo de HC.

Abstract Introduction: Family history of thyroid disease (FHTD) as risk factor for congenital hypothyroidism (CH) in patients with Down syndrome (DS) has not yet been explored. Objective: To determine whether FHTD is associated with an increased risk for CH in DS. Method: Case-control study in 220 neonates with DS. Thyroid function tests of 37 infants with DS and FHTD (cases) were compared with those of 183 DS newborns without FHTD (reference group). Data were analyzed using multivariate logistic regression analysis and adjusted odds ratios (aORs) with their respective 95 % confidence intervals (CI) were calculated. Results: Nine newborns with DS in our sample had CH (4.1 %). FHTD showed an association with CH in neonates with DS (aOR = 8.3, 95 % CI: 2.0-34.3), particularly in males (aOR = 9.0, 95 % CI: 1.6-49.6). In contrast, newborns with DS without FHTD were less likely to suffer from CH (aOR = 0.4, 95 % CI: 0.1-0.8). Conclusions: FHTD detailed evaluation can be an easy and accessible strategy to identify those newborns with DS at higher risk for CH.

Choosing Wisely for Thyroid Conditions: Recommendations of the Thyroid Department of the Brazilian Society of Endocrinology and Metabolism

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.
