ABSTRACT
Introduction: An increased basal metabolism rate and hyperphagia associated with weight loss are among the main clinical manifestations of hyperthyroidism. However, few literature reports are available regarding the adequacy of calorie consumption based on the energy expenditure of the patient. Case Report: A 24-year-old male patient (weight 61.5 kg, height 1.78 m) with a diagnosis of hyperthyroidism due to Graves' disease and initial hormone values consistent with this disease (free T3=17,6 pg/ml; free T4>6,0 ng/dl; TSH<0,004 IU/ml). Indirect calorimetry was performed in order to estimate real energy expenditure and adequacy of the nutritional conducts adopted during hospitalization. The patient had a resting energy expenditure of2574 kcal. Conclusion: The present study suggests that the measurement of energy expenditure by indirect calorimetry is an important tool for the evaluation of the energy requirements and diet adequacy of a patient with thyrotoxicosis due to Graves' disease.
Introducción: El aumento del metabolismo basal, hiperfagia asociada con pérdida de peso son algunas de las principales manifestaciones clínicas que ocurren en el hipertiroidismo. Sin embargo, hay pocos estudios disponibles acerca de la necessidad y del gasto energético del paciente. Caso clínico: Varón de 24 años de edad con 61,5 kg de peso y estatura de 1,78 m, con el diagnóstico de hipertiroidismo por enfermedad de Graves (T3 libre = 17,6 pg/ml; T4 livre >6,0 ng/dl; TSH <0,004 IU/ml) y con los siguientes síntomas: pérdida de peso, aumento de apetito y hiperactividad. La calorimetría indirecta se realizó para estimar el consumo energético real para definir la conduta nutricional durante la hospitalización. El gasto energético basal fue de 2574 kcal. Conclusión: El presente estudio sugiere que la medición del gasto energético por calorimetría indirecta es una herramienta importante para la evaluación de las necesidades de energía y la adecuación de la dieta de un paciente con tirotoxicosis por enfermedad de Graves. Se necesitan más estudios para determinar el impacto de esta conducta en la evaluación de la respuesta al tratamiento del hipertiroidismo.

Introduction: Bioelectrical impedance is a fast, inexpensive, easy, portable, and noninvasive method. A major innovation in the analysis of body composition is segmental bioelectrical impedance. Objectives: To assess the applicability of segmental bioelectrical impedance. Subjects and methods: The study was conducted on female subjects divided into two groups: Group I (n =8) consisted of healthy women and group II (n=25) of obese women with Polycystic Ovary Syndrome (PCOS). All subjects were submitted to examination by total and segmental bioelectrical impedance. Results and discussion: Anthropometric parameters (weight, BMI, total lean mass and total fat mass) showed significant differences between groups. There was a significant difference between groups I and II for all body segments evaluated, except for lean mass of the leg. Conclusion: Procedures of segmental bioelectrical impedance will be increasingly useful in the nutritional assessment of tissue masses, enabling assessment that is more sensitive and monitoring of nutritional care.
Introdução : A impedância bioelétrica é um método rápido, barato, fácil, portátil e nao invasivo. Urna grande inovação na análise da composição corporal é a Impedância Bioelétrica Segmentar. Objetivos: Avahar a aplicabilidade da impedância bioelétrica segmentar. Sujetos e Métodos: o estudo foi realizado com individuos do sexo feminino, divididos em: Group I (n=8) composto por mulheres eutróficas e o Group II (n=25) mulheres obesas com Síndrome do Ovario Policístico (SOP). Todos os individuos foram submetidos ao exame de impedância bioelétrica total e segmentar. Resultados e discussão : Os parâmetros antropométricos de peso, IMC, massa magra total e massa gorda total apresentaram diferencas significativas entre os groups. Houve diferenca significativa para todos os segmentos corporais avahados, com exceção da massa magra da perna entre o group I e II. Conclusão : Procedimentos de impedância bioelétrica segmentar serão cada vez mais úteis na avaliação nutricional de massas teciduais, possibilitando avaliações e monitoramentos mais sensíveis do cuidado nutricional.
