Patients on long-term hemodialysis therapy may develop secondary hyperparathyroidism with oral symptoms. As the life expectancy of the dialysis patient increases, the dentist is seeing these manifestations with increasing frequency. A review of the subject is presented along with a case illustrating dramatic roentgenographic changes in a patient who was ...
Edwards A E - - 1977
Subtle alterations in neurological function are often difficult to identify and even harder to quantitate. The identification of a neurotoxic state existing before overt behavioral changes occur has eluded quantification. It was hypothesized that a challenging signal-detection procedure would be used to assess neurological function of dialysis patients and other ...

1) A stable group of hemodialysis patients in our study do not have a normal response to the cosyntropin test; 2) although one would expect chronic renal failure patients to accommodate to hemodialysis, our study demonstrates that hemodialysis may still serve as a useful stress test; 3) the reduced response ...
Henning H V - - 1977
Plasma triglycerides and cholesterol were measured in controls, non-dialyzed patients with chronic renal insufficiency and uremic patients receiving either regular hemodialysis or hemofiltration treatment. Normal and elevated cholesterol levels remained generally unaffected by chronic hemodialysis and hemofiltration as well. Whereas long-term hemodialysis even up to 59 months (home-dialysis) was unable ...
