RESUMEN
Hyperparathyroidism is a desease caused by increase of parathormone secretion, leading to a misfunction of calcium metabolism. Although not very common among population in general, it is frequently observed in patients with cronic renal disease. It can involve a slight syntomatic form, but as a whole, its main repercurssions occur in skeletic muscles, urinary and intestinal systems. The authors conduct a broad revision of the literature, focusing on the methods of diagnosis and spot checking before and during the operations of parathyroid glands. Surgical recommendations, tatic aspects and types of surgery to be implemented are discussed. A systematization for adequate surgical technics performed at the General Surgery Service of Clementino Fraga Filho Hospital of Federal University of Rio de Janeiro is fully discribed and recommended.
RESUMEN
Objective To research the changes of the lumbar bone mineral density(BMD) in maintenance hemodialysis(HD) patients, and significance of quantitative computed tomography(QCT) on lumbar bone mineral density measurement.Methods The lumbar BMD (L 2～4 ) were measured by QCT in fifty maintenance HD patients ,and a comparison of data was made between HD patients and normal subjects.Results The BMD of HD patients were significantly lower than those of the sex-age matched group,and it were dropping with prolongation of hemodialysis duration. Conclusion The BMD in HD patients decrease obviously,and there was correlation between the BMD and duration. QCT-BMD is a useful sensitive diagnostic method for renal bone disease in HD patients.
