RESUMOCom o objetivo de avaliar os custos e a efetividade das 2 formas de tratamento mais utilizadas em nosso meio para a Doença de Graves, iodo radioativo e tratamento clínico prolongado, analisamos pacientes submetidos a essas terapias na região de Maringá, PR. In this study, we set out to evaluate the costs and effectiveness of the 2 most used therapies in our region, ATD or RAI. 23 patients, 6 men and 16 women, with a mean age of 35.4 years, treated with ATD, and 35 patients, 5 men and 30 women, mean age of 39.4 years, treated with RAI, were studied. After 2 years receiving ATD, 21 patients achieved euthyroidism and 2 remained hyperthyroid. In the RAI group, 21 patients presented hypothyroidism and 13 became euthyroid. To calculate the costs of each therapy, we analyzed the number of visits during this period, the laboratory data and the drugs needed, such as tiamazol and/or thyroxine. The group treated only with ATD needed a higher number of visits and laboratory measurements, with the mean total cost of R$ 1,345.81, while the RAI group spent a mean amount of R$ 622.94. Therefore, the costs of the RAI treatment were 53.5% lower than clinical therapy with ATD. The present study demonstrates that RAI treatment has a lower cost than ATD, being very effective in controlling the hyperthyroidism of Graves' disease. (Arq Bras Endocrinol
Purpose:To compare increment of bone mineral density (BMD) with pamidronate, zoledronate and the isolated effect of proteinous diet in undernourished oophorectomized and non-oophorectomized female rats, besides validating BMD's indexes. Methods: 60 young female Lewis rats were divided into five experimental groups and a control group, oophorectomized and non-oophorectomized. The administration of drugs were submitted to proteinous and aproteinous diets. The variables analyzed were weight, bone densitometry, histomorphometry and biochemical evolution. Results: In weight evaluation, the first interval showed a statistically meaningful increase in oophorectomized sample. In densitometry evaluation, the first interval showed statistically meaningful decrease in four medicated groups and third showed a statistically meaningful increase in 2 non-oophorectomized groups. In laboratory evaluation, there were an increase of total proteins and globulin, decrease of alkaline phosphatase, phosphorus and calcium (except for the oophorectomized) in four medicated groups and increase of phosphorus and calcium in 2 not medicated groups. In histomorphometric evaluation, the oophorectomized groups had smaller increment of BMD. Conclusions: The pamidronate and zoledronate have shown effectives in the increment of BMD. The proteinous diet itself possesses therapeutic effect in BMD though not significant compared with medicated animals. The results of histomorphometry allow validating BMD's indexes in this experimental model. Key words: Osteoporosis. Bone Density. Densitometry. Ovariectomy, Diphosphonates. Rats. RESUMO Objetivo:Comparar o incremento de densidade mineral óssea (DMA) com pamidronato, zoledronato e o efeito isolado de dieta protéica em ratas desnutridas ooforectomizadas e não ooforectomizadas, além de validar índices de DMA. Métodos: 60 ratas jovens Lewis foram divididas em cinco grupos experimentais e um grupo controle, com e sem ooforectomia. A administração das drogas foi submetida às dietas protéica e aprotéica. As variáveis analisadas foram peso, densitometria óssea, histomorfometria e evolução bioquímica. Resultados: Na avaliação ponderal, o primeiro intervalo mostrou aumento estatisticamente significante nos grupos ooforectomizados. Na avaliação densitométrica, o primeiro intervalo mostrou diminuição estatisticamente significante nos quatro grupos medicados e o terceiro mostrou aumento estatisticamente significante nos dois não ooforectomizados. Na avaliação laboratorial, houve aumento de proteínas totais e globulina, diminuição de fosfatase alcalina, fósforo e cálcio (exceto nos ooforectomizados) nos quatro grupos medicados e aumento de fósforo e cálcio nos dois não medicados. Na avaliação histomorfométrica, os grupos ooforectomizados tiveram incremento menor de DMA. Conclusões: O pamidronato e o zoledronato se mostraram efetivos no incremento de DMA. A dieta protéica em si possui efeito terapêutico na DMA, porém menos significativa, comparada aos animais medicados. Os resultados da histomorfometria per...
