ABSTRACT

Introducción: en el presente reporte de caso se presenta una urgencia endocrinológica, el coma mixedematoso. Se considera una descompensación del hipotiroidismo y su mortalidad es alta alcanzando hasta 52% en algunas series de casos. Puede desencadenarse por múltiples factores y su presentación clínica es muy variada ya que comprende la afección de diversos sistemas. Presentación del caso: se presenta el caso de una paciente femenina de 42 años de edad que consultó al servicio de urgencias del Hospital de San José de Bogotá con sospecha inicial de una de falla cardiaca descompensada, sin embargo, cursó con pobre mejoría ante el manejo instaurado, por lo cual se realizaron estudios de extensión en donde se encontró una función tiroidea deprimida. Discusión y conclusiones: en este momento se consideró que la paciente padecía un coma mixedematoso, se instauró manejo con dosis altas de levotiroxina oral con lo cual evolucionó de manera favorable y se logró dar de alta a los pocos días.


Introduction: herein we present an endocrine emergency, myxedema coma, which is a form of decompensated hypothyroidism, whose mortality may be as high as 52% as evidenced in some case series. It may be triggered by multiplefactors and has varied clinical presentations for it affects diverse organ systems. Case presentation:we present the case of a 42-year-old female who presented to the emergency department of Hospital de San José in Bogotá with clinical suspicion of decompensated heart failure upon admission, however, her response was poor to the treatment she received. Extension studies were performed which showed low thyroid function. Discussion and conclusions: at this point the patient was diagnosed with myxedema coma, and was started on high doses of oral levothyroxine, with which she evolved favorably and was discharged a few days later.

ABSTRACT

La coexistencia entre cáncer de tiroides e hipertiroidismo es infrecuente, y la mayoría de las lesiones nodulares a partir de las cuales se documenta un tumor maligno en este grupo de pacientes corresponden a nódulos fríos. Justificado en el creciente número de reportes en la literatura acerca de tumores malignos diagnosticados a partir de nódulos calientes, se realizó una revisión sistemática que tuvo como objetivo determinar los posibles factores asociados con el diagnóstico de cáncer de tiroides a partir de nódulos calientes en pacientes con hipertiroidismo. Los resultados sugieren que el diagnóstico clínico de bocio nodular tóxico, lesiones nodulares de diámetro mayor de 10 mm y tipo histológico compatible con carcinoma folicular, son factores que aumentan por sí solos el riesgo de realizar el diagnóstico de cáncer a partir de un nódulo caliente


Coexistence between thyroid cancer and hyperthyroidism is rare, and most of the nodular lesions from which a malignant tumor is documented in this group of patients correspond to cold nodules. Justified by the increasing number of reports in the literature about malignant tumors diagnosed from hot nodules, a systematic review was carried out to determine possible factors associated with the diagnosis of thyroid cancer from hot nodules in pa-tients with hyperthyroidism. The results suggest that the clinical diagnosis of toxic nodular goiter, nodular lesions of diameter > 10 mm and a histological type compatible with a follicular carcinoma, are factors that on their own increase the risk of making the diagnosis of cancer from a hot nodule

ABSTRACT

INTRODUCCIÓN: el tiroides exhibe una gran avidez por el yodo radioactivo (I131) que al ser fijado por ésta glándula puede determinarse, desde afuera, aprovechando el hecho de que las radiaciones gamma atraviesan los tejidos blandos del cuello y pueden registrarse (Gammagrafía) a distancias apreciables. Desde 1962 Bolivia cuenta con esta tecnología, sin embargo, no cuenta con trabajos similares desde la declaración de país libre de enfermedades secundarias a la deficiencia de Yodo en 1997. El objetivo fue determinar valores de la captación tiroidea de I131 a las 24 horas en adultos jóvenes eutiroideos, residentes de gran altitud. MÉTODO: se realizó un estudio descriptivo transversal, en 76 sujetos obtenidos por intención y seleccionados mediante una entrevista clínica, examen físico dirigido y un consentimiento informado. El procedimiento fue ejecutado por personal calificado en el INAMEN siguiendo las recomendaciones de la OIEA. RESULTADOS: el valor de la captación tiroidea de I131 en 24 horas fue de 18,23 + 5,79% (rango 7,70 ­ 39,70). DISCUSIÓN: los expertos recomiendan establecer valores de referencia actualizados en cada región. Se han descrito variaciones de los valores normales influenciados por el sexo y edad; esta última, aparentemente por una hipofunción tiroidea inversamente proporcional con la edad. CONCLUSIÓN: el valor referencial encontrado en nuestro estudio es concordante con los establecidos en el extranjero, sin embargo, con una tendencia incrementada. Podría deberse a la secuencia cronológica de los estudios comparados en países que ya habían establecido políticas de yodación más tempranamente.


INTRODUCTION: the thyroid exhibits a great avidity for radioactive iodine (I131) which, when fixed by this gland, can be determined from the outside, taking advantage of the fact that gamma radiation passes through the soft tissues of the neck and can be registered (scintigraphy) at appreciable distances. Since 1962, Bolivia has had this technology, however, it does not have similar studies since the declaration of a country free of diseases secondary to iodine deficiency in 1997. The objective was to determine values of the thyroid uptake of I131 at 24 hours in euthyroid young adults, high altitude residents. METHOD: a descriptive cross-sectional study was carried out in 76 subjects obtained by intention and selected by means of a clinical interview, directed physical examination and informed consent. The procedure was carried out by qualified personnel at INAMEN, following IAEA recommendations. RESULTS: the value of the thyroid uptake of I131 in 24 hours was 18.23 + 5.79% (range 7.70 - 39.70). DISCUSSION: experts recommend establishing up-to-date reference values in each region. Variations in normal values influenced by sex and age have been described; the latter, apparently due to a thyroid hypofunction inversely proportional to age. CONCLUSION: the reference value found in our study is consistent with those established abroad, however, with an increased trend. It could be due to the chronological sequence of comparative studies in countries that had already established iodination policies earlier.

ABSTRACT

Se realizó una revisión narrativa sobre la genética del hipotiroidismo congénito (HC). Se utilizaron las bases de datos Medline/PubMed, LILACS-BIREME y SciELO. Se identificaron los estudios originales publicados entre 2000 y agosto de 2020. Las palabras clave utilizadas durante la búsqueda fueron las siguientes: "hipotiroidismo congénito (congenital hypothyroidism)", "genética (genetic)", "polimorfismos de nucleótido único (SNP) (single polymorphisms nucleotid)". Se revisaron 58 estudios originales que informan las bases moleculares del HC. Se ha definido el concepto básico del HC, así como las bases moleculares que están asociados con la aparición de dicho trastorno. La revisión de la literatura ha permitido identificar al menos 12 genes que codifican las proteínas, las cuales, al producirse mutaciones, están implicadas en el HC. De los 12 genes informados que desempeñan un papel importante en el HC, errores en 6 genes se han vinculado con el HC con disgenesia tiroidea, lo cual implica alteraciones en la morfogénesis de la glándula tiroides, mientras que mutaciones en otros 6 genes se han asociado con dishormonogénesis, que genera un bloqueo total o parcial de los procesos bioquímicos implicados en la síntesis y secreción de hormonas tiroideas. La prevalencia en Sudamérica varía aproximadamente desde 1 por cada 1170 hasta 1 por cada 8285 neonatos. El estudio de la genética molecular pone de manifiesto que, en el futuro, aportará datos importantes en cuanto a la identificación de nuevas mutaciones y asociaciones con fenotipos clínicos que podrían relacionarse con el HC, para, de esta manera, potenciar el diagnóstico y tratamiento


A narrative review was conducted on the genetics of congenital hypothyroidism. The Medline/PubMed, LILACS-BIREME, and SciELO databases were used. Original studies published between 2000 and August 2020 were identified. The keywords used during the search were as follows: "congenital hypothyroidism", "genetics", "polymorphisms SNPs". Fifty-eight original studies reviewing the molecular basis of congenital hypothyroidism were reviewed. The basic concept of congenital hypothyroidism has been defined as well as the molecular bases that are associated with the development of this disorder. The literature review has identified at least 12 genes encoding proteins that, when mutations occur, are involved in congenital hypothyroidism. Of the 12 genes reported to play an important role in congenital hypothyroidism, errors in 6 genes have been associated with congenital hypothyroidism with thyroid dysgenesis, which implies alterations in the morphogenesis of the thyroid gland. On the other hand, mutations in 6 other genes have been associated with dyshormonogenesis that generates a total or partial blockage of the biochemical processes involved in the synthesis and secretion of thyroid hormones. The prevalence in South America is reported to vary from approximately 1 per 1000 to 1 per 8000 newborns. The study of molecular genetics shows that in the future it will contribute to the identification of new mutations and associations with clinical phenotypes that could be related to congenital hypothyroidism, thus enhancing diagnosis and treatment

ABSTRACT

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)

ABSTRACT

Resumen Introducción: La elastografía por ondas de corte (SWE) ha demostrado ser predictiva de malignidad en nódulos tiroideos. Objetivo: Determinar mediante SWE, el punto de corte de la rigidez con mayor especificidad y sensibilidad para detectar nódulos tiroideos que requieren cirugía. Métodos: Estudio transversal de pacientes con nódulos tiroideos evaluados ultrasonográficamente en un periodo de tres años; se empleó la clasificación TI-RADS y mediante SWE se determinó la rigidez de los nódulos. Con el sistema Bethesda se clasificaron las muestras histopatológicas y mediante curva ROC se obtuvo el punto de corte de la rigidez con mayor especificidad y sensibilidad. Resultados: 41 % de los nódulos fue TI-RADS 5 y 59 %, TI-RADS 1-4. En los TI-RADS 5, la mediana de rigidez de los nódulos con categoría IV-VI del sistema Bethesda fue de 35.9 kPa y en los nódulos con TI-RADS 1-4, 21.6 kPa. En los nódulos TI-RADS 5, la rigidez > 32.5 kPa tuvo especificidad de 75 % y sensibilidad de 57 % para detectar los que requieren cirugía; en los TI-RADS 1-4, el valor de corte de 21.5 kPa tuvo especificidad de 63 % y sensibilidad de 51 %. Conclusión: La rigidez determinada por SWE es útil para detectar nódulos que requerirán exploración quirúrgica.


Abstract Introduction: Shear-wave elastography (SWE) has been shown to be predictive of malignancy in thyroid nodules. Objective: To determine, by SWE, the stiffness cutoff point with the highest specificity and sensitivity to detect thyroid nodules that require surgery. Methods: Cross-sectional study of ultrasonographically-evaluated patients for thyroid nodules over a period of three years; the TI-RADS classification system was used, and nodule stiffness was determined by SWE. Histopathological specimens were classified using the Bethesda system, and the stiffness cutoff point with the highest specificity and sensitivity was obtained using ROC curves. Results: Forty-one percent of the nodules were classified as TI-RADS 5, and 59 %, as TI-RADS 1-4. In TI-RADS 5 nodules, median stiffness of those in Bethesda system IV-VI categories was 35.9 kPa; in nodules with TI-RADS 1-4, 21.6 kPa. In TI-RADS 5 nodules, a cutoff point > 32.5 kPa had a specificity of 75 % and sensitivity of 57 % to detect those requiring surgery; in TI-RADS 1 to 4 nodules, a cutoff point of 21.5 kPa had a specificity of 63 % and sensitivity of 51 %. Conclusion: SWE-determined stiffness is useful to detect nodules that require surgical evaluation.

ABSTRACT

A paralisia periódica hipocalêmica tireotóxica é uma complicação rara do hipertireoidismo. Caracteriza-se por episódios de fraqueza muscular recorrente, associado à tireotoxicose e hipocalemia. Ocorre frequentemente em pacientes do sexo masculino e de origem asiática. Nesse contexto, o objetivo deste estudo é descrever o relato de caso de um paciente acometido por paralisia periódica hipocalêmica tireotóxica com redução acentuada da qualidade de vida e internações recorrentes devido a quadro agudo de tetraparesia flácida ascendente associado a hipocalemia grave por não adesão ao tratamento do hipertireoidismo. A paralisia periódica hipocalêmica tireotóxica apresenta evolução favorável quando reconhecida e tratada com controle inicial dos sintomas para normalização sérica do potássio e posterior resolução do quadro tireotóxico.


Thyrotoxic hypokalemic periodic paralysis is a rare complication of hyperthyroidism. The issue has been characterized by episodes of recurrent muscle weakness associated with thyrotoxicosis and hypokalemia. It occurs most often in male patients of Asian origin. This study aims on describing the case report of a patient affected by thyrotoxic hypokalemic periodic paralysis with intense reduction in life quality and recurrent hospitalizations due to ascending acute flaccid tetraparesis associated with severe hypokalemia due to non-adherence to treatment of hyperthyroidism. Thyrotoxic hypokalemic periodic paralysis presents a favorable evolution when identified and treated with initial symptom control for serum potassium normalization and subsequent resolution of the thyroid toxicity.

ABSTRACT

Objetivo: avaliar a prevalência de glaucoma entre os portadores de patologias tireoidianas, acompanhados na Clínica Escola de Saúde (CES) do núcleo de Medicina do Centro Universitário Christus (UNICHRISTUS), Fortaleza ­ Ceará ­ Brazil. Métodos: estudo transversal e descritivo de prontuários de pacientes diagnosticados com hipotireoidismo ou hipertiroidismo pelo Código Internacional de Doenças (CID-10) no sistema eletrônico da CES, entre 2013 e 2018. Pacientes triados foram convidados a realizar um exame oftalmológico na Fundação Leiria de Andrade (FLA). Resultados: dos 499 prontuários triados, 22,8% (114) possuíam diagnóstico confirmado para tireoidopatias, sendo 85,9% (98) com hipotireoidismo, e 14,0% (16) com hipertireoidismo. Desses, 72,0% (101) eram mulheres e 28,0% (13) homens. A faixa etária mais prevalente foi entre 41 a 60 anos de idade, correspondendo a 46,4% (53), sendo 65,7% (75) de Fortaleza ­ Ceará ­ Brasil. As principais comorbidades associadas às tireoidopatias foram hipertensão arterial sistêmica, representando 43,8% (50), seguida de dislipidemia, 26,3% (30) e diabetes mellitus tipo 2 em 13,1% dos pacientes (15). Do total, 25 pacientes foram encaminhados à FLA, 84,0% (21) relataram doenças oculares prévias, 4,0% (1) diagnosticado com escavação aumentada constitucional e 12,0% (3) com diagnóstico de glaucoma primário de ângulo aberto. Conclusão: apesar da hipótese de associação entre o glaucoma e as tireoidopatias, o tamanho amostral não possibilitou inferências sobre o risco aumentado de sua correlação, assim como em outros estudos preexistentes na literatura, sendo necessários mais estudos para elucidar com maior precisão essa associação relevante. Palavras-chave: Glaucoma; Tireoide; Hipotireoidismo; Hipertireoidismo; Pressão Intraocular. Resumo Objective: To evaluate the prevalence of ophthalmological pathologies, between thyroidopathies, for early diagnosis of glaucoma in patients seen at the Clínica Escola de Saúde (CES) of the Medicine Center of the Centro Universitário Christus (UNICHRISTUS), Fortaleza ­ Ceará ­ Brazil. Methods: A cross-sectional study and descriptive analysis of medical records of patients diagnosed with hypothyroidism or hyperthyroidism by the International Classification of Diseases (ICD-10) on the CES electronic system, between 2013 and 2018. Screened patients were invited to perform an eye examination at Fundação Leiria de Andrade (FLA). Results: Of the 499 medical records screened, 22.8% (114) had a confirmed diagnosis for thyroid disorders, 85.9% (98) with hypothyroidism, and 14.0% (16) with hyperthyroidism. Of these, 72.0% (101) were women and 28.0% (13) men. The most prevalent age group was between 41 and 60 years old, corresponding to 46.4% (53), being 65.7% (75) from Fortaleza - Ceará. The main comorbidities associated with thyroid diseases were systemic arterial hypertension, 43.8% (50), followed by dyslipidemia, 26.3% (30), and type 2 diabetes mellitus in 13.1% of patients (15). Of the total, 25 patients were referred to the FLA, 84.0% (21) reported previous eye diseases, 4.0% (1) diagnosticated with increased constitutional excavation, and 12.0% (3) with a diagnosis of primary open-angle glaucoma. Conclusion: Despite the hypothesis of an association between glaucoma and thyroidopathy, the sample size didn't allow inferences about the increased risk of its correlation, as well as in other pre-existing studies in the literature, requiring further studies to elucidate this relevant association.

ABSTRACT

Epidermal inclusion cyst (EIC) of the thyroid is extremely rare in the clinical practice. A handful of cases have been documented in the past in the world literature. A giant EIC of the thyroid is hitherto unreported. This lesion may arise from the squamous metaplasia of the thyroid follicular cells. Though non-neoplastic, giant forms can cause compression of the vital structures of the neck. In the present case, we have described a giant epidermal inclusion cyst successfully managed with surgical management.

ABSTRACT

ABSTRACT The thyroidectomy is the most frequently executed procedure in head and neck surgery. Since its first description by Kocher, the transverse cervical incision has been the main access to the thyroid site, as it provides broad exposure of the central neck compartment. Despite the meticulous suture of the incision, the development of a scar with variable dimensions is unavoidable and, hence, some patients might not agree to the approach, due to this consequence. The transoral endoscopic thyroidectomy vestibular access (TOETVA) gains importance as an alternative to the traditional surgery, since it avoids the formation of visible scars. The objective of this study is to develop a systematic review on the currently available literature to evaluate possible complications related to the TOETVA. The systematic review was based on the databases of Medline, Cochrane library, Embase and Scielo/Lilacs, resulting in the selection of six studies, which were compared in regard of the type of study duration of the study and identified complications. Our study showed that TOETVA is related to complications similar to the ones identified in the conventional approach, such as hematoma, seroma, recurrent laryngeal nerve injury, hypoparathyroidism, surgical site infection. The TOETVA was associated to a higher risk of thermic injury of the skin and mentual nerve paresthesia. Moreover, it was possible to conclude that TOETVA is a safe procedure for well selected patients, with favorable conditions and concerned about the aesthetic outcome. The risk of complications of the procedure should always be explained to those patients.


RESUMO A tireoidectomia é o procedimento cirúrgico mais frequentemente realizado na cirurgia de cabeça e pescoço. Desde sua descrição por Kocher, a incisão cervical transversa constitui o principal acesso à loja tireoideana e permite ampla exposição à região central do pescoço. Apesar do fechamento meticuloso da incisão, uma cicatriz de dimensões variáveis é inevitável, e certos pacientes podem discordar de tal abordagem. A tireoidectomia vestibular endoscópica transoral (TOETVA) ganha importância como alternativa à cirurgia tradicional, pois evita a formação de cicatrizes visíveis. O objetivo de estudo é realizar uma revisão sistemática da literatura das possíveis complicações da TOETVA. Foi realizada revisão sistemática da literatura nas bases de dados Medline, The Cochrane Library, Embase e SciElo/Lilacs, sendo selecionados seis artigos e tabulados os dados de tipo de estudo, período do estudo e complicações apresentadas. O estudo mostra que a TOETVA apresenta complicações semelhantes à técnica convencional, como hematoma, seroma, lesão de nervo laríngeo recorrente, hipoparatireoidismo, além de infecção de sítio cirúrgico, com maior risco de lesão térmica da pele e parestesia por lesão do nervo mentual. Em adição, foi possível concluir que a TOETVA é uma técnica segura para pacientes bem selecionados, com condições favoráveis e com especial preocupação com resultados estéticos, devendo sempre ser orientados sobre possíveis complicações.

ABSTRACT

RESUMO Objetivo: Descrever os cuidados com o uso de insulinas disponibilizadas pelo SUS e analisar os fatores associados aos cuidados inadequados. Método: Estudo transversal com 113 pessoas com Diabetes Mellitus de um ambulatório de Goiânia-GO. Foram coletados dados em prontuários sobre conservação, preparo e administração de insulina que foram classificados em adequados e inadequados. Resultados: Do total de participantes,58,4% eram mulheres e a média de idade foi 48 anos. Hipertensão arterial foi relatada por 70,8% e 89,0% apresentaram hemoglobina glicada ≥7%. A totalidade dos usuários de insulina realizavam pelo menos um tipo de cuidado inadequado e 62,8% realizavam quatro ou mais. Os mais frequentes foram:conservarem locais não recomendados (46,7%), não aplicar insulina 30 minutos antes da refeição (87,5%), não avaliar presença de grumos no frasco de insulina NPH (71,9%) e não retirar a insulina da geladeira entre 15 e 30 minutos antes da aplicação (88,7%). Não houve diferença estatisticamente significante com as variáveis de exposição analisadas, porém a maior proporção de quatro ou mais cuidados inadequados ocorreu nas mulheres, nos jovens, naqueles com 11 ou mais anos de estudo, tempo de doença superior a 10 anos e, entre os que aplicam insulina uma ou duas vezes ao dia. Conclusão: Houve alta prevalência de cuidados inadequados e grande variabilidade de práticas, reforçando a importância da implementação da linha de cuidados em Diabetes Mellitus em todos os níveis de atenção à saúde.

ABSTRACT Objective: To describe management practices of insulin provided by the SUS and analyze the factors associated with insulin management mistakes. Method: Cross-sectional study addressing 113 individuals with Diabetes Mellitus from an outpatient clinic in Goiânia, GO, Brazil. Data concerning insulin storage, preparation, and administration were collected from the patients' medical records and classified as appropriate or inappropriate. Results: 58.4% of participants were women aged 48 years old on average. Hypertension was reported by 70.8%, and glycated hemoglobin was ≥7% in 89.0%. All the patients made at least one insulin management mistake, and 62.8% made four or more mistakes. The most frequent mistakes were: storing insulin in non-recommended places (46.7%), not injecting insulin 30 minutes before meals (87.5%), not checking for the presence of lumps in the NPH insulin vial (71.9%), and not removing the insulin from the refrigerator between 15 and 30 minutes before injection (88.7%). No significant statistical differences were found among the exposure variables, though women, young individuals, those with 11 or more years of schooling, having the disease for more than ten years, and injecting insulin once or twice a day, more frequently made four or more management mistakes. Conclusion: A high prevalence of insulin management mistakes and considerable variability of practices were identified, reinforcing the importance of implementing a DM line of care at all healthcare system levels.

ABSTRACT

OBJECTIVES@#To study the effect of levothyroxine sodium tablets on the growth and development and thyroid function in preterm infants with thyroid dysfunction.@*METHODS@#A retrospective analysis was performed for 82 preterm infants who were born in the Department of Obstetrics of the First People's Hospital of Yunnan Province, from January 1, 2013 to December 31, 2017, and these infants were hospitalized after birth in the Department of Neonatology of the hospital. They were regularly followed up to observe growth and development and thyroid function at the outpatient service of the Department of Neonatology. According to thyroid function test results, they were divided into an abnormal thyroid function group (observation group; @*RESULTS@#There were no significant differences in physical development indices (body length, body weight, and head circumference) between the observation and control groups at various gestational ages after follow-up to the corrected age of 12 months (@*CONCLUSIONS@#Early diagnosis and reasonable treatment can reduce the impact on growth and development in preterm infants with thyroid dysfunction. Most preterm infants tend to have transient thyroid dysfunction, while those with positive results of neonatal screening are more likely to develop permanent thyroid dysfunction.

ABSTRACT

BACKGROUND@#Thyroid dysfunction is associated with cardiovascular diseases. However, the role of thyroid function in lipid metabolism remains partly unknown. The present study aimed to investigate the causal association between thyroid function and serum lipid metabolism via a genetic analysis termed Mendelian randomization (MR).@*METHODS@#The MR approach uses a genetic variant as the instrumental variable in epidemiological studies to mimic a randomized controlled trial. A two-sample MR was performed to assess the causal association, using summary statistics from the Atrial Fibrillation Genetics Consortium (n = 537,409) and the Global Lipids Genetics Consortium (n = 188,577). The clinical measures of thyroid function include thyrotropin (TSH), free triiodothyronine (FT3) and free thyroxine (FT4) levels, FT3:FT4 ratio and concentration of thyroid peroxidase antibodies (TPOAb). The serum lipid metabolism traits include total cholesterol (TC) and triglycerides, high-density lipoprotein, and low-density lipoprotein (LDL) levels. The MR estimate and MR inverse variance-weighted method were used to assess the association between thyroid function and serum lipid metabolism.@*RESULTS@#The results demonstrated that increased TSH levels were significantly associated with higher TC (β = 0.052, P = 0.002) and LDL (β = 0.041, P = 0.018) levels. In addition, the FT3:FT4 ratio was significantly associated with TC (β = 0.240, P = 0.033) and LDL (β = 0.025, P = 0.027) levels. However, no significant differences were observed between genetically predicted FT4 and TPOAb and serum lipids.@*CONCLUSION@#Taken together, the results of the present study suggest an association between thyroid function and serum lipid metabolism, highlighting the importance of the pituitary-thyroid-cardiac axis in dyslipidemia susceptibility.

ABSTRACT

Thyroid gland diseases are the most common endocrinopathies in feline practice. Diagnosis and surgical treatment must base on solid anatomical knowledge about the gland size, localization, and blood supply. However, some textbooks provide a general anatomical description of the thyroid gland of domestic carnivores. Thus, specific details of the feline gland are missing. The present study aimed to investigate the dimensions, topography, and arterial supply of the thyroid gland in Brazilian shorthair cats and, therefore, provide additional data to diagnose and treat feline thyroid diseases. Thirty Brazilian shorthair cats formalin-fixed cadavers (15 male and 15 female) were injected with red-stained latex solution by a canula in the thoracic aorta. The necropsy unit of the Rural Federal University of Rio de Janeiro donated the specimens. The study included only adult animals with no history of thyroid disease. After the fixation period, the cadavers were dissected to investigate the measurements (length, width at cranial and caudal poles, and thickness), topography, and in situ arterial supply of the thyroid lobes. The mean measurements of the length, cranial pole width, caudal pole width, and thickness in the right lobe were 19.39 ± 3.10 mm, 5.36 ± 1.40 mm, 3.67 ± 0.93 mm, and 1.30 ± 0.29 mm, respectively; and 20.29 ± 3.35 mm, 4.85 ± 1.58 mm, 3.88 ± 0.91 mm, 1.64 ± 0.65 mm in the left lobe, respectively. There were no statistical differences (P > 0.05) in the comparison of the measures between sexes or antimers (sides). Pearson's linear correlation detected a positive, moderate (r = 0.55), and significant (P < 0.05) correlation between the right and left lobe lengths. In 70% of the cats, both left and right lobes had the cranial poles located at the same level. Typically, the lobes extended between the first to the eighth tracheal ring. However, the cranial pole of some lobes located as cranially as the cricoid cartilage level, and the caudal pole as caudally as the 12th tracheal ring. Fifty-six percent of the cats had a ventrally located isthmus. In all the sampling, one single thyroid artery emerged as a branch of the common carotid artery and provided branches directly to the thyroid lobe, isthmus and the adjacent muscles and esophagus. Besides establishing average dimensions of normal thyroid lobes in Brazilian shorthair cats, this study detected no significant difference between the average measurements of right and left lobes. Also, a positive linear correlation between the length and width of the right and left lobes became evident. Therefore, the practitioner must consider suspicious any length asymmetry between right and left thyroid lobes until further endocrine test proves otherwise. Most of the cats had the right and left thyroid lobe positioned at the same transversal level; however, positional asymmetries are not uncommon. Unlike dogs, Brazilian shorthair cats have only a single artery to supply each lobe: the thyroid artery. In a feline thyroidectomy, the surgeon must avoid blindly ligating the thyroid artery since this vessel also provided numerous branches to adjacent muscles and esophagus. In a bilateral thyroidectomy, the ventral region between lobes should be thoroughly inspected for the common presence of an isthmus. Sometimes, the surgeon may need to extend the incision caudally beyond the 12th tracheal ring level to visualize the gland tissue entirely.(AU)

ABSTRACT

Extraskeletal Ewing sarcoma is a rare event, and extraskeletal Ewing sarcoma of the thyroid gland is even rarer. It has non-specific clinical manifestation and difficulty in early diagnosis. The diagnosis mainly depends on histology and immunohistochemistry. It possesses the features of high malignancy, high rate of local recurrence, and distant metastasis. Currently, the aggressive multimodal treatment contains surgery, chemotherapy, and radiotherapy. This study presented a case of extraskeletal Ewing sarcoma arising in the thyroid gland of a 30-year-old woman, who presented with supraclavicular mass and sense of dysphagia obstruction in Department of Otolaryngology, Head and Neck Surgery, Second Xiangya Hospital, Central South University in 2018. Imaging studies demonstrated a cystic-solid mass in inferior of the left leaf of thyroid gland and in the posterior of the trachea and esophagus. The patient underwent localized tumor resection. The pathological diagnosis revealed that it was a small round cell tumor, and the immunohistochemistry results were considered to be extraskeletal Ewing sarcoma. Subsequently, the patient was given chemotherapy and local radiation therapy. There was no evidence of tumor recurrence or metastasis.

ABSTRACT

Introdução: o presente artigo analisou e avaliou a prevalência de dinapenia em associação da idade dos Hormônio Estimulador da tireoide (TSH) e T3 em idosos da Universidade Aberta à Terceira Idade ­ UATI. A tireoide produz e secreta os hormônios triiodotironina (T3) e tiroxina (T4), responsáveis por controlar o metabolismo celular. O termo dinapenia tem sido utilizado para descrever a diminuição da força muscular relacionada à idade separando desta forma, a dinapenia da redução da massa muscular. Metodologia: trata-se de um estudo de corte transversal que investigou 63 mulheres com idade entre 60 e 95 anos, resultando numa idade média das participantes foi de 69,6 anos, não institucionalizadas, matriculados no projeto "Universidade Aberta à Terceira Idade (UATI)", da Universidade Estadual da Bahia (UNEB). A força de preensão palmar (FPP) foi avaliada em quilograma (kg), por meio do dinamômetro digital manual da marca INSTRUTHERM. Resultados: foram diagnosticados com dinapenia as pacientes que possuíram a FPP inferior a 20 kg. Descobriu-se que 23 idosas (36,51%) foram diagnosticadas com dinapenia. A correlação entre as variáveis TSH e dinapenia foi positiva e fraca Spearman=0.17 (p-valor= 0.22). Assim, a relação entre o FPP e a idade não parece ser linear possuindo uma correlação negativa e fraca: Spearman= -0.11 (p-valor= 0.39). Conclusão: o nível sérico de TSH e idade não tiveram associação significativa com a presença de dinapenia. Houve associação entre T3 sérico e dinapenia, porém não é possível identificar em qual quartil está essa associação.


Introduction: this article analyzed and evaluated the prevalence of dynapenia in association with the age of thyroid stimulating hormones (TSH) and T3 in the elderly at Universidade Aberta do Idoso ­ UATI. The thyroid produces and secretes the hormones triiodothyronine (T3) and thyroxine (T4) responsible for the control of cellular metabolism. The term dynapenia has been used to describe the decrease in muscle strength related to age, separating dynapenia from the reduction of muscle mass. Methodology: this is a cross-sectional study that investigated 63 women between 60 and 95 years old, resulting in an average age of participants of 69.6 years old, non-institutionalized, registered in the project the Open University Of The Elderly (UATI)", of Bahia State University (UNEB). The Hand Grip Strength (HGS) was measured in kilograms (kg), using the INSTRUTHERM manual digital dynamometer. Results: patients with FPP less than 20 kg were diagnosed with dynapenia. It was found that 23 elderly women (36.51%) were diagnosed with dynapenia. The correlation between TSH and dynapenia variables was positive and weak Spearman = 0.17 (p-value = 0.22). Thus, the relationship between (FPP) and age does not appear to be linear with a weak and negative correlation: Spearman = -0.11 (p-value = 0.39). Conclusion: the serum TSH level and age had no significant association with the presence of dynapenia. There was an association between(T3) and serum dinapenia, but it is not possible to identify in which quartile this association is found.

ABSTRACT

Abstract Background and objectives: In this study, we aimed to investigate the predictive value of different airway assessment tools, including parts of the Simplified Predictive Intubation Difficulty Score (SPIDS), the SPIDS itself and the Thyromental Height Test (TMHT), in intubations defined as difficult by the Intubation Difficulty Score (IDS) in a group of patients who have head and neck pathologies. Methods: One hundred fifty-three patients who underwent head and neck surgeries were included in the study. The Modified Mallampati Test (MMT) result, Thyromental Distance (TMD), Ratio of the Height/Thyromental Distance (RHTMD), TMHT, maximum range of head and neck motion and mouth opening were measured. The SPIDSs were calculated, and the IDSs were determined. Results: A total of 25.4% of the patients had difficult intubations. SPIDS scores >10 had 86.27% sensitivity, 71.57% specificity and 91.2% Negative Predictive Value (NPV). The results of the Receiver Operating Curve (ROC) analysis for the airway screening tests and SPIDS revealed that the SPIDS had the highest area under the curve; however, it was statistically similar to other tests, except for the MMT. Conclusions: The current study demonstrates the practical use of the SPIDS in predicting intubation difficulty in patients with head and neck pathologies. The performance of the SPIDS in predicting airway difficulty was found to be as efficient as those of the other tests evaluated in this study. The SPIDS may be considered a comprehensive, detailed tool for predicting airway difficulty.


Resumo Justificativa e objetivos: Neste estudo, avaliamos o valor preditivo de diferentes ferramentas de avaliação das vias aéreas, incluindo componentes do Escore Simplificado Preditivo de Intubação Difícil (ESPID), o próprio ESPID e a Medida da Altura Tireomentoniana (MATM), em intubações definidas como difícies pelo Escore de Dificuldade de Intubação (EDI) em um grupo de pacientes com patologia de cabeça e pescoço. Método: Incluímos no estudo 153 pacientes submetidos a cirurgia de cabeça e pescoço. Coletamos os resultados do Teste de Mallampati Modificado (TMM), Distância Tireomentoniana (DTM), Razão Altura/Distância Tireomentoniana (RADTM), MATM, amplitude máxima de movimentação da cabeça e pescoço e da abertura da boca. Os ESPIDs foram calculados e os EDIs, determinados. Resultados: Observamos intubação difícil em 25,4% dos pacientes. Os escores de ESPID > 10 tiveram sensibilidade de 86,27%, especificidade de 71,57% e valor preditivo negativo de 91,2% (VPN). O resultado da análise da curva de operação do receptor (curva ROC) para os testes de avaliação das vias aéreas e ESPID mostrou que o ESPID tinha a maior área sob a curva; no entanto, foi estatisticamente semelhante a outros testes, exceto para o TMM. Conclusões: O presente estudo demonstra o uso prático do ESPID na previsão da dificuldade de intubação em pacientes com patologia de cabeça e pescoço. O desempenho do ESPID na predição de via aérea difícil mostrou-se tão eficiente quanto os demais testes avaliados neste estudo. O ESPID pode ser considerado ferramenta abrangente e detalhada para prever via aérea difícil.

ABSTRACT

Introducción: Las bases fisiopatológicas del Síndrome de ovario poliquístico pueden predisponer a mayor riesgo de autoinmunidad a las mujeres que tienen esta condición y existen evidencias, aunque escasas, de mayor prevalencia de autoinmunidad tiroidea en ellas. Objetivos: Determinar la frecuencia de marcadores serológicos de autoinmunidad tiroidea en mujeres con Síndrome de ovario poliquístico e identificar si existe asociación entre la presencia de ellos y las concentraciones de progesterona y testosterona. Métodos: Se realizó un estudio en 50 mujeres con Síndrome de ovario poliquístico y 50 sin el síndrome. Se realizaron determinaciones de autoanticuerpos tiroideos (anti tiroglobulina (Anti-Tg) y anti peroxidasa (anti-TPO) a las mujeres de ambos grupos de estudio. Se realizaron determinaciones de hormonas (testosterona y progesterona) solo al grupo de estudio de mujeres con SOP. Se crearon categorías por anticuerpos: Positivo si los títulos fueron superior al rango de referencia y negativo dentro del rango. Se consideró respuesta autoinmune positiva, cuando al menos uno de los anticuerpos se encontró elevado. Para la asociación entre la presencia de autoinmunidad y las variables independientes se hicieron análisis bivariados mediante comparación de medias y test no paramétricos. Se consideró un nivel de significancia de α = 0,05. Resultados: En las mujeres con Síndrome de ovario poliquístico, 62 por ciento mostraron anticuerpos positivos y 14 por ciento en las sin el síndrome. En las mujeres sin síndrome, de las 7 mujeres con marcadores de autoinmunidad positivos, en 6 (85,7 por ciento) el anti-Tg fue el que dio positivo. No hubo diferencias significativas en cuanto a la asociación con los niveles de testosterona y progesterona. Conclusiones: Las mujeres con Síndrome de ovario poliquístico tienen mayor frecuencia de desarrollar respuesta autoinmune tiroidea, independiente de los niveles de progesterona y testosterona(AU)


Introduction: The physio-pathological bases of polycystic ovary syndrome may predispose women with this condition to a higher risk of autoimmunity and there is evidence, albeit scarce, of higher prevalence of thyroid autoimmunity in them. Objectives: Determine the frequency of serological markers of thyroid autoimmunity in women with polycystic ovary syndrome and identify whether there is an association between the presence of them and progesterone and testosterone concentrations. Methods: A study was conducted in 50 women with polycystic ovary syndrome and 50 without the syndrome. Determinations of thyroid autoantiantibodies (anti-thyroglobulin (Anti-Tg) and anti-peroxidase (anti-TPO) were made to women in both study groups. Hormone determinations (testosterone and progesterone) were made only to the study group of women with PCOS. Categories were created by antibodies: Positive if the titles were greater than the reference range, and negative if within the range. It was considered a positive autoimmune response when at least one of the antibodies was found increased. For the association between the presence of autoimmunity and independent variables, bivariate analyses were performed by means comparison and non-parametric tests. It was considered a significance level of α =0.05. Results: In women with polycystic ovary syndrome, 62 percent showed positive antibodies and 14 percent in those without the syndrome. In women without the syndrome, of the 7 women with positive autoimmune markers, in 6 (85.7 percent) the anti-Tg was the one that tested positive. There were no significant differences in the association with testosterone and progesterone levels. Conclusions: Women with polycystic ovary syndrome are more often able to develop thyroid autoimmune response, independently from the progesterone and testosterone levels(AU)
