The diagnosis of hypoparathyroidism with neurological findings occurring years after thyroid surgery is considered to be rare. The authors describe 3 cases of hypoparathyroidism associated to brain calcifications diagnosed many years after partial thyroidectomy. Two patients were admitted to Emergency Services presenting with seizures, without a previous diagnosis of hypoparathyroidism. The diagnosis was suspected adding the biochemical analysis to the scar on the neck. The CT, which was performed more than 20 years after surgery, showed large cerebral calcifications in both cases. The third patient did not have neurological symptoms, but presented basal and cerebellar calcifications that were demonstrated in the CT. All patients were treated with calcium and vitamin D with great improvement of clinical status. Adding to a case published previously, we count 4 cases from the same region. Thyroidectomies were very common in this region poor in dietary iodide. Since the clinical follow up was inadequate, we suspect that undetected cases similar to these may exist in the present moment.
Este trabalho teve como objetivo relatar o emprego da técnica reconstrutiva do retalho de padrão axial da artéria angular da boca, após exérese cirúrgica de um tumor cutâneo localizado na região labial de um cão. Para correção do defeito facial ocasionado pela exérese, optou-se pela reconstrução plástica com a utilização do retalho, que se revelou eficiente na cicatrização da ferida cirúrgica. A realização de cirurgias reconstrutivas para reparação de defeitos cutâneos faciais é uma prática recorrente na Medicina Veterinária. Pelas características das lesões originadas, principalmente em cirurgias oncológicas e processos traumáticos, o uso de retalhos subdérmicos e de padrão axial é comumente preconizado.
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.
