RESUMO

Graves' disease (GD) is the leading cause of hyperthyroidism and diffuse toxic goiter in iodine-sufficient geographi-cal areas. GD is associated with classical manifestations such as ophthalmopathy and thyroid dermopathy, in addi-tion to diffuse goiter, which may be the site of carcinomas, as a complication. Case report: A 52-year-old woman presented with goiter and symptoms compatible with hyperthyroidism, such as heat intolerance, weight loss, fati-gue, increased sweat, tachycardia, fine tremors, increased intestinal transit, anxiety, emotional lability, insomnia, exophthalmos, and pretibial myxedema. A complementary investigation confirmed the diagnosis of hyperthyroidism (high free T4 and total T3 levels and low thyroid-stimulating hormone - TSH levels). Ultrasound images showed dif-fuse enlargement of the thyroid lobes by approximately 10 times and the presence of three thyroid nodules, one of which was larger than 2 cm with heterogeneous echogenicity and vascularization throughout the nodule; ultrasoun-d-guided fine needle aspiration revealed cytology compatible with Bethesda IV; scintigraphy revealed a low uptake area (cold nodule) amid a diffuse high-uptake goiter. A thyroidectomy was performed, and the anatomical specimen diagnosis revealed papillary thyroid carcinoma in the right lobe, with adjacent parenchyma compatible with GD. Histopathological examination of the skin showed the presence of myxedema compatible with Graves' dermopathy. The patient evolved with the normalization of TSH levels and a reduction of cutaneous manifestations. Conclusion:GD abnormalities may not be restricted to the classic clinical manifestations, and a careful investigation may reveal the coexistence of carcinomas. (AU)


A doença de Graves (DG) é a principal causa de hipertireoidismo e bócio difuso tóxico em áreas geográficas com iodo suficiente. DG está associada a manifestações clínicas clássicas como oftalmopatia e dermopatia da tireoide, além do bócio difuso, que pode ser sítio de carcinomas, como uma complicação. Relato de caso: Mulher de 52 anos apresentou bócio e sintomas compatíveis com hipertireoidismo como intolerância ao calor, emagrecimento, fadiga, sudorese aumentada, taquicardia, tremores finos, trânsito intestinal aumentado, ansiedade, labilidade emocional, insônia, exoftalmia e mixedema pré-tibial. A investigação complementar confirmou o diagnóstico de hipertireoidis-mo (níveis elevados de T4 livre e T3 total; níveis baixos de hormônio estimulante da tireoide - TSH). As imagens ultrassonográficas mostraram aumento difuso dos lobos tireoidianos em aproximadamente 10 vezes e a presença de três nódulos tireoidianos, um dos quais, maior que 2 cm, com ecogenicidade e vascularização heterogêneas em todo o nódulo, cuja punção aspirativa por agulha fina guiada por ultrassom revelou citologia compatível com Bethesda IV; e a cintilografia evidenciou uma área de baixa captação (nódulo frio) em meio a um bócio difuso de alta captação. Foi realizada tireoidectomia e o diagnóstico da peça anatômica revelou carcinoma papilífero de tir-eoide em lobo direito, com parênquima adjacente compatível com DG. O exame histopatológico da pele mostrou a presença de mixedema compatível com dermopatia de Graves. A paciente evoluiu com normalização dos níveis de TSH e redução das manifestações cutâneas. Conclusão: As anormalidades da DG podem não estar restritas às manifestações clínicas clássicas, e uma investigação criteriosa pode revelar a coexistência de carcinomas, (AU)

RESUMO

La enfermedad por coronavirus SARS-CoV-2 que surgió en el año 2019 (COVID-19), ha obligado al rápido desarrollo de vacunas para prevenir su propagación e intentar controlar la pandemia. Dentro de las vacunas desarrolladas, las primeras en ser aprobadas con una tecnología nueva en el campo de la vacunación, fueron las vacunas basadas en ARNm (ácido ribonucleico mensajero), que lograron tasas de efectividad cercanas al 95 % para la prevención de la enfermedad COVID-19 grave. Los eventos adversos comunes son reacciones locales leves, pero ha habido varios informes de pacientes que desarrollaron tiroiditis subaguda y disfunción tiroidea después de recibir la vacuna contra SARS-CoV-2. Este artículo presenta dos casos de tiroiditis subaguda poco después de recibir la vacuna contra COVID-19


The SARS-CoV-2 coronavirus disease which emerged in 2019 (COVID-19), has forced the rapid development of vaccines to prevent the spread of infection and attempt to control the pandemic. Among the vaccines developed, one of the first to be approved with a new technology in the field of vaccination, was the mRNA (messenger ribonucleic acid) vaccine, with rates of effectiveness close to 95% for the prevention of severe COVID-19 disease. Common adverse events are mild local reactions, but there have been some reports of patients developing sub-acute thyroiditis and thyroid dysfunction after receiving the SARS-CoV-2 vaccine. This article presents two case reports of subacute thyroiditis shortly after receiving the COVID-19 vaccine

RESUMO

Abstract Fetal thyroid complications in pregnancy are uncommon, and are commonly related to the passage of substances through the placenta. The excessive iodine intake during the pregnancy is a well-known mechanism of fetal thyroid enlargement or goiter, and invasive procedures have been proposed for the treatment of fetal thyroid pathologies. In the present report, we demonstrate two cases from different centers of prenatal diagnosis of fetal thyroid enlargement and/or goiter in three fetuses (one pair of twins, wherein both fetuses were affected, and one singleton pregnancy). The anamnesis revealed the ingestion of iodine by the patients, prescribed from inadequate vitamin supplementation. In both cases, the cessation of iodine supplement intake resulted in a marked reduction of the volume of the fetal thyroid glands, demonstrating that conservative treatmentmay be an option in those cases. Also, clinicians must be aware that patients may be exposed to harmful dosages or substances during pregnancy.


Resumo As complicações fetais da tireoide na gravidez são incomuns e são comumente relacionadas à passagem de substâncias pela placenta. A ingestão excessiva de iodo durante a gravidez é um mecanismo bem conhecido de aumento da tireoide ou bócio fetal, e procedimentos invasivos foram propostos para o tratamento de patologias da tireoide fetal. No presente relato de caso, demonstramos dois casos de diferentes centros de diagnóstico pré-natal de aumento da tireoide fetal e/ou bócio em três fetos (um par de gêmeos, em que ambos os fetos foram afetados, e uma gravidez única). A anamnese revelou a ingestão de iodo pelos pacientes prescrita por suplementação inadequada de vitaminas. Nos dois casos, a interrupção da ingestão de suplemento de iodo resultou em uma redução acentuada do volume das glândulas tireoides fetais, demonstrando que o tratamento conservador pode ser uma opção nestes casos. Além disso, os médicos devem estar cientes de que as pacientes podem ser expostas a doses ou substâncias nocivas durante a gravidez.

RESUMO

La hemiagenesia tiroidea representa un trastorno congénito caracterizado por la ausencia de desarrollo de uno de los lóbulos tiroideos, asociado o no a ausencia del istmo. Es más frecuente en las mujeres y por lo general se presenta como falta del lóbulo izquierdo, con hipertrofia compensatoria del lóbulo contralateral. Su diagnóstico es generalmente incidental o por manifestaciones del lóbulo tiroideo presente. Se hizo una revisión bibliografía, en donde no se encontraron casos reportados en Venezuela de hemiagenesia o agenesia tiroidea, describiéndose el siguiente. Presentamos a una paciente de 50 años de edad, conocida con hipotiroidismo desde los 31 años, negando cualquier cirugía en el área de cabeza y cuello. Desde febrero 2019 presentó aumento progresivo de volumen en región anterior de cuello. Al examen físico se observó aumento de volumen en región anterior derecha del cuello, palpándose lóbulo tiroideo derecho aumentado de tamaño, de aspecto nodular, no doloroso. En ecosonograma tiroideo se concluyó como bocio tiroideo derecho de aspecto multinodular, con ausencia del lóbulo izquierdo. Perfil tiroideo dentro de límites normales. Se lleva a mesa operatoria corroborándose ausencia del lóbulo izquierdo y presentado en la biopsia definitiva hiperplasia nodular en el lóbulo derecho. Se discute su frecuencia, la forma de presentación y se hace revisión de la literatura(AU)


Thyroid hemiagenesis represents a congenital disorder characterized by the absence of development of one of thyroid lobes, associated or not with absence of isthmus. It is more frequent in women and generally presents as absence of the left lobe, with compensatory hypertrophy of the contralateral lobe. Its diagnosis is generally incidental or by manifestations of the present thyroid lobe. A bibliography review was made, where no cases reported in Venezuela of hemiagenesis or thyroid agenesis were found, describing the following. We present a 50-year-old patient, known with hypothyroidism since she was 31, denying any surgery in the head and neck area. Since February 2019, presented a progressive increase in volume in the anterior neck region. On physical examination, an increase in volume was observed in right anterior region of the neck, palpating an enlarged right thyroid lobe, with a nodular appearance and not painful. In a thyroid echo-sonogram, it was concluded as a right thyroid goiter with a multinodular appearance, with the absence of the left lobe. Thyroid profile within normal limits. It is taken to the operating table, confirming the absence of the left lobe and presented in the definitive biopsy nodular hyperplasia in the right lobe. Its frequency, form of presentation, and literature review are discussed(AU)

RESUMO

RESUMEN Objetivo: evaluar la prevalencia de yodo deficiencia y de bocio en mujeres indígenas gestantes de cinco áreas no metropolitanas en Colombia. Materiales y métodos: estudio de corte transversal descriptivo. Se incluyeron mujeres embarazadas de cualquier edad gestacional sin condiciones patológicas del embarazo, atendidas en los centros de salud comunitarios o en sus residencias. Se excluyeron aquellas con comorbilidades presentes al momento del embarazo y también a quienes recibían suplementos con yodo. Muestreo aleatorio simple. Se midieron las características sociodemográficas y obstétricas, la concentración de yodo en orina y la presencia de bocio de acuerdo a la metodología de la Organización Mundial de la Salud. Se realizó un análisis descriptivo. Resultados: 189 gestantes indígenas fueron candidatas a ingresar al estudio, de las cuales 2 no aceptaron participar y 62 tenían criterios de exclusión, finalmente se analizaron 125. La concentración urinaria de yodo tuvo una mediana de 184,4 µg/L (min-max: 12,0-390,0). Un total de 42 gestantes (33,6%) tenían yodo deficiencia (< 100 µg/L) y se evidenció bocio (grado 1-2) en 43 (34,4%). No se identificó bocio grados 3 o 4. Conclusiones: embarazadas indígenas residentes en áreas no metropolitanas evidenciaron alta prevalencia de bocio y yodo deficiencia. Se requiere evaluar los efectos materno-perinatales e implementar intervenciones nutricionales.


ABSTRACT Objective: To assess the prevalence of goiter and iodine deficiency in indigenous pregnant women coming from five non-metropolitan areas in Colombia. Materials and methods: Descriptive cross-sectional cohort study that included pregnant women of any gestational age with no pregnancy-related conditions, seen in community health centers or in their homes. Patients with comorbidities at the time of pregnancy and those who were receiving iodine supplementation were excluded. Simple random sampling was used. The sociodemographic and obstetric characteristics, urinary iodine concentration and the presence of goiter were measured in accordance with the World Health Organization methodology. A descriptive analysis was performed. Results: Of 189 indigenous pregnant women who were candidates to enter the study, 2 declined participation, and 62 had exclusion criteria, and 125 were included in the final analysis. The mean urinary iodine concentration was 184.4 µg/L (min-max: 12.0-390.0). A total of 42 women (33.6%) had iodine deficiency (< 100 µg/L), and goiter (grade 1-2) was found in 43 (34.4%). No grade 3 or 4 goiter was identified. Conclusions: A high prevalence of goiter and iodine deficiency was found in indigenous pregnant women living in non-metropolitan areas. There is a need to assess maternal and perinatal effects and to implement nutritional interventions.

RESUMO

El hipotiroidismo es la disfunción tiroidea más frecuente, resultante de una disminución de la actividad biológica de las hormonas tiroideas en los tejidos. El objetivo es realizar una revisión y actualización del hipotiroidismo adquirido en la infancia y adolescencia con énfasis en el hipotiroidismo primario. La causa más común es la tiroiditis de Hashimoto o tiroiditis linfocitaria crónica. La característica distintiva es el impacto profundo en el crecimiento esquelético, maduración y desarrollo puberal, con potencial repercusión en la talla adulta. Los signos y síntomas del hipotiroidismo adquirido son similares a los adultos y, en general, no se asocia con compromiso del desarrollo neuromadurativo.La presunción clínica se confirma con niveles elevados de tirotrofina y disminuidos de tiroxina libre. Las metas del tratamiento incluyen lograr adecuado crecimiento, maduración sexual, desarrollo neuromadurativo y cognitivo óptimo. En la mayoría de los pacientes, el tratamiento de reemplazo revierte los signos y síntomas.


Hypothyroidism is the most frequent thyroid dysfunction. It is the consequence of a decrease in the biological activity of thyroid hormones in target tissues. The aim of this paper is to review and update acquired hypothyroidism in childhood and adolescence with emphasis on primary hypothyroidism due to its greater frequency. Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis, is the most common cause of primary acquired hypothyroidism. The distinctive feature is the profound impact on skeletal growth, maturation, and pubertal development, with potential implications on adult height. Signs and symptoms of acquired hypothyroidism are similar to those reported in adults and are generally not associated with neurodevelopmental impairment. Biochemi confirmation of primary hypothyroidism requires the finding of elevated thyrophine and decreased free thyroxine levels. Treatment goals are to achieve normal growth and maturation as well as cognitive development. In most of the patients, replacement treatment reverses symptoms and signs of hypothyroidism and may decrease goiter size.

RESUMO

Introducción: Los valores de tirotropina (TSH) pueden modificarse marcadamente durante el embarazo, en relación con diversos factores clínicos y bioquímicos. Objetivo: Identificar los factores clínicos y bioquímicos asociados con la tirotropina en embarazadas aparentemente sanas. Métodos: Estudio descriptivo, transversal, con 247 gestantes aparentemente sanas del municipio Plaza de la Revolución., en el periodo comprendido de septiembre de 2015 a enero de 2019. Variables analizadas: edad materna y gestacional, trimestre del embarazo, color de la piel, paridad, hábito de fumar, antecedentes familiares de enfermedad tiroidea (APF), consumo de suplementos con yodo, índice de masa corporal (IMC), presencia de bocio al examen físico, TSH, tiroxina total (T4t) y libre (T4l), triyodotironina total (T3t) y libre (T3l), gonadotropina coriónica (hCG), anticuerpos contra la peroxidasa tiroidea (AcTPO) y la tiroglobulina (AcTg) y yoduria. Resultados: La TSH (1,66 ± 0,91mUI/L) tuvo una asociación negativa con la edad materna (r = -0,17; p = 0,008), la paridad (nulíparas 1,80 ± 0,90 mUI/L, multíparas 1,45 ± 0,89 mUI/L; p = 0,003), los APF (positivos 1,56 ± 0,91 mUI/L, negativos 1,81 ± 0,89 mUI/L; p = 0,03), la T4t (r = -0,15; p = 0,02), la T4l (r = -0,23; p = 0,000) y la hCG (r = -0,52; p = 0,001). Mostraron una relación directa la edad gestacional (r = 0,25; p = 0,000) y el uso de suplementos yodados (consumo 1,96 ± 0,72mUI/L, no consumo 1,62 ± 0,93 mUI/L; p = 0,03). Conclusiones: La tirotropina presenta una relación inversa con la edad materna, la paridad, los antecedentes familiares de enfermedad tiroidea, la T4 total y libre, y la gonadotropina coriónica, y una relación directa con la edad gestacional y el consumo de suplementos con yodo(AU)


Introduction: Thyrotropin (TSH) values can be sharply modified during pregnancy, in relation to various clinical and biochemical factors. Objective: Identify clinical and biochemical factors associated with thyrotropin in seemingly healthy pregnant women. Methods: Descriptive, cross-sectional study with 247 seemingly healthy pregnant women from Plaza de la Revolution municipality in the period from September 2015 to January 2019. Variables analyzed: maternal and gestational age, trimester of pregnancy, skin color, pregnancies, smoking habit, family history of thyroid disease (APF), consumption of iodine supplements, body mass index (BMI), presence of goiter to physical examination, TSH, total and free (T4l) thyroxine (T4t), total (T3t) and free (T3l) triiodothyronine, chorionic gonadotropin (hCG), antibodies against thyroid peroxidase (AcTPO) and thyroglobulin (AcTg) and urinary iodine. Results: TSH (1.66 ± 0.91mUI/L) had a negative association with maternal age (r = -0.17; p x 0.008), pregnancy (nulliparas 1.80 ± 0.90 mUI/L, 1.45 ± 0.89 mUI/L; p x 0.003), APF (positive 1.56 ± 0.91 mUI/L, negative 1.81 ± 0.89 mUI/L; p x 0.03), the T4t (r = -0.15; p s 0.02), the T4l (r = -0.23; p x 0.000) and the hCG (r = -0.52; p x 0.001). They showed a direct relationship with gestational age (r x 0.25; p x 0.000) and the use of iodine supplements (consumption 1.96 ± 0.72mUI/L, not consumption 1.62 ± 0.93 mUI/L; p x 0.03). Conclusions: Thyrotropin has an inverse relationship with maternal age, pregnancies, family history of thyroid disease, total and free T4, and chorionic gonadotropin, and a direct relationship with gestational age and consumption of iodine supplements(AU)

RESUMO

ABSTRACT As pregnant women are susceptible to changes in iodine, which can cause miscarriage, goiter, thyroid nodules, hypothyroidism, in addition to fetal neurological impairment or development. The aim of this study was to verify the implications of the iodine alteration in each gestational trimester and its consequences of physiological justification. The review was based on PRISMA. Searching for articles that took place in March 2020 without delimiting data. As bases consulted were the Clinical Trials, Cochrane Library, Lilacs and Medline (PubMed). The descriptors were combined as follows: "pregnancy" AND "iodine deficiency". Articles that addressed iodine deficiency and its implications were included. The selection followed the steps of reading the titles, abstracts and full articles. To assess the methodological quality of the studies, the STROBE Instruction instrument was used. The research resulted in 1,266 studies and 11 were included. In assessing methodological quality, the lowest score was and the maximum 20. According to studies, the fourth most affected by iodine loss are the second and third, it is possible to increase the volume and pneumatic nodules, subclinical hypothyroidism, pre-eclampsia, among others. The damages caused by iodine deficiency in the first or second trimester are still reversible, therefore, they need to be diagnosed early, to guarantee an iodic homeostasis and prevent damage to the health of the mother-child binomial.

RESUMO

Se estudió una paciente de 33 años de edad con antecedentes patológicos de Bocio tiroideo difuso desde hace 8 años, que acude al cuerpo de guardia por presentar falta de aire, fiebre de 39-40 °C, dolor de garganta y palpitaciones hace alrededor de tres días. Al examen físico se le constató exoftalmos, mucosas hipocoloreadas y faringe purulenta y punteada de color blanquecina, artralgia y taquicardia. Referente a los exámenes complementarios presentó anemia, leucopenia y pancitopenia luego de haber consumido propiltiouracilo (50mg) por un período prolongado; por lo que se concluye como agranulocitosis como consecuencia de una reacción adversa al propiltiouracilo. Luego de ser tratada la paciente se recupera de su gravedad con el uso de factores estimulantes de colonias de granulocitos(AU)


A female 33-year-old patient with an 8-year history of diffuse thyroid goiter presents at the emergency service with shortness of breath, a 39-40ºC fever, a sore throat and palpitation of 3 days' evolution. Physical examination revealed exophthalmos, hypopigmented mucosas, a purulent pharynx dotted with whitish spots, arthralgia and tachycardia. Complementary tests found anemia, leukopenia and pancytopenia upon consumption of propylthiouracil (50 mg) for a long period. The diagnosis is agranulocytosis resulting from an adverse reaction to propylthiouracil. After being treated the patient recovered from her severe status with the use of granulocyte colony stimulating factors(AU)

RESUMO

El hipotiroidismo subclínico (HS), elevación de tirotrofina con hormonas tiroideas normales, junto al bocio, aumentó la frecuencia en las últimas décadas. Con el objetivo de relacionar la prevalencia de bocio y HS con el consumo de agua subterránea como factor de riesgo etiológico poblacional, se analizaron 879 historias clínicas de un centro médico de Glew, en el conurbano bonaerense Sur. Se estudió la población según edad (20-60 y 12-19 años) y tipo de agua consumida (potabilizada o napa subterránea). El agua subterránea fue consumida por el 70.5% del grupo de 20 a 60 años (n = 559, 79.9% mujeres) y por el 66.3% del grupo de 12 a 19 años (n = 57, 81.4% mujeres). En el grupo de 20 a 60 años la prevalencia de HS en consumidores de agua potabilizada y subterránea fue del 1% y 57.8% (p < 0.0001) y la de bocio de 3.8% y 38.9% (p < 0.0001), respectivamente; con un riesgo atribuible al agua subterránea de 57% para HS y 35% para bocio. En el grupo de 12 a 19 años, la prevalencia de HS fue 6.9% y 52.6% (p < 0.0001) y de bocio 13.8% y 77.2% para los grupos de agua potabilizada y subterránea, (p < 0.0001) respectivamente; con un riesgo atribuible al agua subterránea de 46% para HS y 61% para bocio. El análisis fisicoquímico mostró presencia de nitratos (entre 24 y 83 mg/l) en aguas de pozos y ausencia en agua potable. La prevalencia aumentada de HS y bocio podrían deberse a la acción disruptora tiroidea de los nitratos.


Subclinical hypothyroidism (SH), elevation of the level of thyrotrophin with normal thyroid hormones, along with goiter (glandular size > 25g), increased in recent decades. In order to relate the prevalence of goiter and SH with the consumption of groundwater, as a population etiological risk factor, we analyzed 879 clinical histories from a medical center in the city of Glew in the South Buenos Aires suburbs. The population was studied according to age (20 to 60 and 12 to 19 years) and type of water consumed (potable water or groundwater). Groundwater was consumed by 70.5% of the group from 20 to 60 years old (n = 559, 79.9% women) and by 66.3% of the group from 12 to 19 years old (n = 57, 81.4% women In the group of 20 to 60 years, the prevalence of SH in potable water and groundwater users was 1% and 57.8% (p < 0.0001) and the goiter rate of 3.8% and 38.9% (p < 0.0001) respectively; with an attributable risk to groundwater of 57% for HS, and 35% for goiter In the group of 12 to 19 years, the prevalence of SH was 6.9% and 52.6% (p < 0.0001) and goiter 13.8% and 77.2% for the water and groundwater groups (p>0.0001) respectively, with an attributable risk of 46% for HS y 61% for goiter. The physicochemical analysis showed the presence of nitrates in the range of 24 to 83 mg/l in groundwater and absence in potable water. The increased prevalence of HS and goiter could be due to the thyroid disrupting action of nitrates.

RESUMO

El bocio congénito es una patología infrecuente, que se genera por alteración de la función tiroidea fetal de causa endógena o exógena: disfunción tiroidea materna, déficit de aporte de yodo en la dieta o secundario a la toma de medicación. La repercusión en la maduración del feto, la compresión de estructuras adyacentes debido al aumento de tamaño, lo cual puede ser un factor de riesgo de obstrucción de la vía aérea y de lesiones hipóxico-isquémicas, hacen que el diagnóstico y tratamiento de esta patología sea de vital importancia. Habitualmente, se diagnostica por ecografía en el segundo o tercer trimestre de embarazo, pero la resonancia magnética (RM) se ha convertido en una técnica diagnóstica complementaria e importante ante un eventual tratamiento intraparto


Congenital goiter is an uncommon condition caused by altered fetal thyroid function of endogenous or exogenous cause (maternal thyroid dysfunction, iodine deficiency in the diet or secondary to taking medication). The impact on the mature development of the fetus, as well as the compression of adjacent structures due to increased size, which may be a risk factor for airway obstruction and hypoxic-ischemic lesions, make the diagnosis and treatment of this pathology of vital importance. It is usually diagnosed by ultrasound in the second or third trimester of pregnancy, but magnetic resonance imaging (MRI) has become a complementary and important diagnostic technique in the event of an intrapartum treatment procedure

RESUMO

Introdução: A comida tem um papel proeminente na obtenção do iodo e uma das melhores estratégias é a iodização do sal. No Brasil, a Anvisa reduziu as doses de iodo no sal de cozinha desde 2014. Portanto, é importante avaliar a concentração urinária de iodo (CIU) em nossa população. Com base no exposto, propõe-se avaliar a CIU das gestantes, associando-a à frequência de bócio materno, aborto e peso neonatal. Métodos: Trata-se de um estudo observacional com um corte transversal composto por 37 pacientes atendidos no Serviço de Obstetrícia da Faculdade de Medicina de Barbacena e uma clínica particular em Juiz de Fora. A CIU foi verificada em 24 horas de urina. Resultados: A média de CIU foi de 213,6 µg/l de urina, com dose mínima de 29 µg/l e máxima de 437 µg/l. A glândula tireoide foi avaliada durante o exame clínico prénatal (palpação da glândula) e em 24 pacientes (38,1%) foi considerada normal. A palpação da glândula tireoide foi associada à CIU. Houve maior iodúria em gestantes com glândula não palpável (p = 0,004; T = 14,13). Não houve associação entre a CIU e história de aborto ou peso fetal ao nascimento (p > 0,05). Conclusões: Apesar de ser uma amostra pequena da população, identificamos pacientes expostas ao déficit. No entanto, a CIU não parece estar associada ao peso do recém-nascido ou a abortos, mas à dosagem de TSH e ao tamanho da glândula tireoide. Assim, a palpação da glândula tireoide poderia ser usada como uma medida indireta do CIU. (AU)


Introduction: Food has a prominent role in providing iodine and one of the best strategies is salt iodization. The Brazilian Health Regulatory Agency has reduced iodine content in table salt since 2014. Therefore, there is a need for evaluating urinary iodine concentration in our population, especially after the modified recommendations. Based on the above, we sought to assess urinary iodine concentration in pregnant women, associating it with frequency of maternal goiter, abortion and neonatal weight. Methods: This observational, cross-sectional study included 37 patients seen at the Obstetrics Service of Barbacena Medical School and a private clinic in Juiz de Fora, both in the state of Minas Gerais, Brazil. Iodine concentration was determined in 24- hour urine through chromatography. Results: The mean 24-hour urine iodine was 213.6 µg/l, with minimum and maximum measures of 29 µg/l and 437 µg/l, respectively. The thyroid gland was assessed by prenatal clinical examination (palpation of the gland). In 24 patients (38.1%) it was considered normal. Palpation of the thyroid gland was associated with 24-hour urine iodine concentration, although a higher iodine concentration was identified in pregnant women with non-palpable gland (p = 0.004; T = 14.13). There was no association between 24-hour urine iodine concentration and history of abortion or birth weight (p > 0.05). Conclusions: This study, although based on a small sample of the population, was important to identify that even in areas where iodine is considered sufficient there may be patients exposed to iodine deficit. However, urinary iodine concentration does not appear to be associated with birth weight or abortion frequency but is associated with thyroid-stimulating hormone (TSH) level and thyroid gland size, suggesting that clinical evaluation of the thyroid gland is an important element for predicting urinary iodine concentration. Thus, palpation of the thyroid gland could be used as an indirect measure of urinary iodine concentration. (AU)

RESUMO

Bócio é o aumento não inflamatório e não neoplásico da glândula tireoide em animais adultos e recém-nascidos. Uma das principais causas envolvidas é a deficiência nutricional de iodo. Relata-se neste trabalho, a ocorrência de três surtos de bócio em bovinos. Na primeira propriedade (Propriedade A), 60 bezerros foram afetados, sendo que 20 morreram logo após o nascimento, 30 recuperaram-se e 10 permaneceram doentes e tiveram remissão dos sinais apenas após tratamento parenteral com iodo. Na segunda propriedade (Propriedade B) uma vaca e seu feto foram acometidos e na terceira (Propriedade C) dois bezerros foram afetados. Os principais sinais clínicos observados nos bezerros foram aumento de volume bilateral na região cervical ventral, emagrecimento, dificuldade respiratória, hipotricose e desenvolvimento corpóreo retardado. Na propriedade A foi relatada ainda a ocorrência de abortamentos. Macroscopicamente, os bezerros e o feto apresentavam tireoide aumentada, vermelho-escura, com vascularização evidente e edema subcutâneo cervical. No surto dois também foi observado, à necropsia, aumento de volume da glândula tireoide da vaca. Microscopicamente, a tiroide dos bezerros e do feto apresentava folículos tireoidianos hiperplásicos, heterogêneos, destituídos de coloide e com interstício acentuadamente vascularizado. A tireoide da vaca era semelhante à dos bezerros, no entanto, possuía quantidade maior de coloide. Em todos os casos a suplementação mineral era realizada por meio da mistura de sal mineral com sal branco. Na Propriedade A o sal branco era não iodado e misturado em partes iguais com o sal mineral. Na Propriedade B o sal também era misturado a um sal branco não iodado na proporção e 1:2, respectivamente. Na Propriedade C o sal mineral e o sal branco não iodado eram ofertados em cochos separados no campo e, segundo relato do proprietário, os animais priorizavam o consumo do sal branco. Em todas as propriedades acompanhadas foi recomendada a interrupção da adição de sal branco na mistura mineral e a administração de iodo aos bezerros acometidos. Após essas medidas não foram observados novos casos nas propriedades. Apesar de ser uma enfermidade bem conhecida, ainda são poucos os relatados de casos de bócios em bovinos no Brasil. Além disso, pouco se sabe sobre as reais deficiências minerais de cada região, e que simples orientações de manejo nutricional ainda são necessárias.(AU)


Goiter is a non-inflammatory and non-neoplastic enlargement of the thyroid gland in adults and neonates. One of the main causes involved is the nutritional deficiency of iodine. In this study three outbreaks of goiter in cattle are reported. In the first outbreak (Farm A) 60 calves were affected, of which 20 died soon after birth, 30 recovered and 10 remained sick. In the second outbreak (Farm B) a cow and its fetus were affected and in the third outbreak (Farm C) two calves were affected. The main clinical signs observed were bilaterally enlarged thyroid glands, weight loss, respiratory distress, hypotrichosis and myxedema. Additionally in the Farm A abortions were reported. Macroscopically the thyroid of the calves and fetus was enlarged, dark red with evident vascularization and cervical subcutaneous edema. In the Farm B the cow showed enlarged thyroid gland as well. Microscopically the calves and the fetus had hyperplastic and heterogeneous thyroid follicles with absence of colloid and vascularized interstitium. The thyroid of the cow was also hyperplastic, but had higher amount of colloid. In all outbreaks the mineral supplementation was performed by mixing non-iodized white salt with the mineral mixture. On the property A the white salt was non-iodized and mixed in equal parts with the mineral salt. At property B the salt was also mixed to a non-iodized white salt in ratio and 1:2, respectively. In the property C, mineral salt and non-iodized white salt were offered in separate troughs in the field, and according to the owner's report the animals prioritized the consumption of white salt. In all the monitored properties it was recommended to stop the addition of white salt in the mineral mixture and the administration of iodine to the affected calves. After these measurements no new cases were observed in the properties. Despite being a well-known disease, there are still few reported cases of goiter in cattle in Brazil. Moreover, little is known about the actual mineral deficiencies of each region, and that simple nutritional management guidelines are still needed.(AU)

RESUMO

El hipotiroidismo congénito es la enfermedad endócrina más frecuente en neonatología y suele transcurrir sin sintomatología clara en ésta etapa de la vida. Es la principal causa de retardo mental tratable cuyo pronóstico radica en el diagnóstico oportuno y tratamiento precoz. El propósito de este artículo es evidenciar cómo situaciones no habituales del comportamiento clínico que despiertan sospecha y el empleo del tamizaje neonatal hacen herramientas eficaces para la detección temprana de ésta patología. De acuerdo con la revisión bibliográfica; además, en este caso, presentamos una situación que debe profundizar el análisis de la etiología ya que la dishormonogénesis es un tipo de hipotiroidismo primario congénito caracterizado por un déficit permanente de hormonas tiroideas que se acompaña de bocio, tiene una transmisión autosómica recesiva y puede requerir confirmación mediante pruebas genéticas.


Congenital hypothyroidism is the most frequent endocrine disease in neonatology and usually occurs without clear symptoms in this stage of life. It is the main cause of treatable mental retardation whose prognosis lies in the timely diagnosis and early initiation of treatment. The purpose of this article is to show that unusual situations of clinical behavior that arouse suspicion and the use of neonatal screening make effective tools for the early detection of this pathology. According to the bibliographic review. Furthermore, in this case, we present a situation that should deepen the analysis of the etiology since the dyshormonogenesis is a type of congenital primary hypothyroidism characterized by a permanent deficit of thyroid hormones that is usually accompanied by goiter, has an autosomal recessive transmission and can require confirmation through genetic tests.

RESUMO

ABSTRACT Objective This study aims to compare the prevalence of laryngopharyngeal reflux signs between two groups of patients undergoing thyroidectomy for voluminous goiter: substernal goiters and voluminous cervical goiter without thoracic extension. Subjects and methods A retrospective case-control study was performed with data retrieved of the charts of the patients submitted to thyroidectomies occurred at a tertiary care center (Head and Neck Surgery Department, University of São Paulo Medical School) between 2010 and 2014. The selected thyroidectomies were allocated in two groups for study: patients with substernal goiters and patients with voluminous cervical goiter without thoracic extension. Cervical goiters were selected by ultrasonography mensuration. Clinical criterion was used to define substernal goiter. Results The average thyroid volume in patients with substernal goiter was significantly greater than the average volume in patients with only cervical goiter (p < 0.001). The prevalence of signs of reflux laryngitis at laryngoscopy was significantly greater in substernal goiter patients (p = 0.036). Moreover, substernal goiter was considered as the unique independent variable for high reflux laryngitis signs at laryngoscopy (OR = 2.75; CI95%: 1.05-7.20; p = 0.039) when compared to only cervical goiter patients. Conclusion This study shows a significant association between substernal goiters and signs of laryngopharyngeal reflux at preoperative laryngoscopy. Therefore, when compared with voluminous cervical goiters, the substernal goiters increase the chance of reflux laryngitis signs in patients.
