Total parathyroidectomy followed by partial autotransplantation was effective in reducing PTH serum levels in patients with terminal kidney disease. The elevation of serum calcium during the suppression test was not able to inhibit the autograft gland secretion of PTH. The assessment of parathyroid graft function demonstrated an inability to respond to the stimulus of hypocalcemia induced by EDTA, although there was a partial recovery, in late postoperative period.
Brown tumors are equally found in secondary and primary hyperparathyroidism. Craniofacial brown tumors involve the orbit, usually because of the osteodystrophy process that involves the maxilla and paranasal sinuses. The lesions do not necessarily need to be excised and may regress spontaneously after the control of hyperparathyroidism.
RESUMOObjetivos: Estimar a população elegível para o tratamento de pacientes com hiperparatireoidismo secundário (HPTS), não controlados com terapia convencional, bem como avaliar a utilização de recursos para o tratamento dessa população com cinacalcete ou paratireoidectomia (PTX). Métodos: Utilização da técnica Delphi por painel de especialistas. A pesquisa foi realizada utilizando questionário estruturado, enviado por meio eletrônico aos especialistas, e seguida de encontro presencial. Os custos foram obtidos de bases de dados governamentais. Apenas custos médicos diretos foram incluídos, sob a perspectiva do Sistema Único de Saúde (SUS) (em reais no ano de 2014). Os dados foram avaliados pelo Microsoft Excel versão 2013. Resultados: A população no cenário de mundo real indicada para o tratamento com cinacalcete foi de 7.705 pacientes. Já a população real encaminhada para a PTX foi de 7.691 pacientes, sendo esse número 76,3% maior que a população ideal com indicação de PTX, que foi de 1.822 pacientes. O custo estimado do tratamento com cinacalcete foi de R$ 27.712,95 (considerando a dose recomendada em bula para cinacalcete, de 30 a 180 mg/ dia) e de R$ 16.841,85 para PTX (incluindo os períodos pré e pós-cirúrgico). A análise de sensibilidade foi baseada na dose média de cinacalcete, conforme o estudo EVOLVE (66,8 mg/dia). Nesse cenário, o custo do tratamento com cinacalcete foi de R$ 11.924,13 (57% menor que o cenário com a dose de bula). Conclusão: No cenário SUS, o número de pacientes encaminhados para PTX foi 76,3% maior que os idealmente indicados à cirurgia, o que ocorre devido à falta de opções terapêuticas.
Chyluria is an inappropriate urinary excretion of chyle that turns the urine milky. A nutritional approach based on low-fat/high-protein content diet associated or not with medium-chain triglyceride (MCT) showed to be an efficient conservative treatment to improve the milky urine appearance in a patient with chyluria. Case report: A 30-year-old female patient was admitted with chyluria of unknown etiology. An ureteropyeloscopy revealed a single lesion in each kidney, both with linear aspect and measuring 5 mm in extension. These lesions were located close to the renal papillae and were leaking a cloudy and milky fluid. Both lesions were laser cauterized followed by improvement of the milky urine. However, the chyluria relapsed after few months and a low-fat/high-protein content diet with 10 g of soybean oil to meet the requirements essential fatty acids (EFA) and with MCT from coconut oil as alternative to prepare foods was started. Few weeks later the patient returned reporting consistent improvement of the milky urine appearance related with the use of the diet. However since the diet was tasteless and time consuming to prepare, she reported low compliance to diet with MCT and the milky urine relapsed. The MCT was discontinued and the diet with EFA source was maintained with better compliance. Since then the chyluria remains in remission. In conclusion, the dramatic improvement of the milky urine with low-fat/high-protein diet with EFA source observed in our patient demonstrates that this nutritional approach is efficient with fast results to treat chyluria during long term.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
