conclusion the open-cell stent is effective and its performance is higher than that obtained with the closed-cell stent for treating central vein stenosis or occlusion in hemodialysis patients. results for the open-cell stent group, 159 patients were diagnosed as central vein stenosis and 98 were occlusion. for the closed-cell stent group, 78 were stenosis and 66 were occlusion. there were two ...

background chronic kidney disease related mineral and bone disease (ckd-mbd) is a worldwide challenge in hemodialysis patients. in senegal, number of dialysis patients is growing but few data are available about their bone disorders. objectives to describe patterns of ckd-mbd in senegalese dialysis patients. patients and methods we performed a cross-sectional study including patients from three...

The first human hemodialysis in the history of medicine was performed by Georg Haas in 1924 in the town of Giessen, Germany. The procedure lasted only 15 minutes, and hirudin served as the anticoagulant. Haas was able to develop a dialyzer consisting of U-shaped collodion tubes immersed in a dialysate bath placed in a glass cylinder. He performed several hemodialysis procedures in uremics betwe...

Peritoneal dialysis catheter ruptures have been managed by immediate removal and subsequent reinsertion of the catheter which inevitably entails interruption in peritoneal dialysis and a need for vascular access. A 36-year-old man on continuous ambulatory peritoneal dialysis complaining of dialysate leakage was found to have a small rupture near the outer cuff of the peritoneal dialysis cathete...

Blood leakage and blood loss are serious life-threatening complications occurring during dialysis therapy. These events have been of concerns to both healthcare givers and patients. More than 40% of adult blood volume can be lost in just a few minutes, resulting in morbidities and mortality. The authors intend to propose the design of a warning tool for the detection of blood leakage/blood loss...

Ignorance of the true length of the DNA molecules in the chromosomes of higher organisms has always been a major obstacle to understanding chromosome structure. Consequently, attempts have been made, usually with the aid of electron microscopy, to estimate the size of DNA in higher organisms. Solari' has reported the longest such DNA measured before now-a DNA fiber from a sea urchin sperm at le...
