Clinical and animal studies suggest that peritoneal absorption of fluid and protein from dialysate to peritoneal tissue, and to blood and lymph circulation, occurs concomitantly with opposite flows of fluid and protein, i.e., from blood to dialysate. However, until now a theoretical explanation of this phenomenon has been lacking. A two-phase distributed model is proposed to explain the bidirec...

The main limitation of haemodialysis techniques is the scarce removal of solute in the range of middle to high molecular weight that may cause a progressive accumulation of these molecules with complications in the long term [1]. Moreover haemodialysis requires large amount of dialysate fluid for the removal of uremic metabolites placing a considerable cost burden on the health care provider. T...

The first objective of this study was to validate the use of water at 85°C ± 5°C to achieve high-level disinfection of a clean-in-place extracorporeal dialysis circuit. The second objective was to demonstrate that applying this hot water method to the entire fluid pathways of a newly designed dialysis instrument, including an integral reverse-osmosis membrane, routinely allowed the production o...

Peritoneal tuberculosis is a rare but a severe disease in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). A 60 years old male, who had been the CAPD program during the last 5 months, was admitted to our clinic with fever, loss of appetite, night sweats, cough, weight loss and cloudy dialysate. Mycobacteria cultures of blood and pleural fluid were sterile. Bacterial culture...

The choroid plexus epithelium is a secretory epithelium par excellence. However, this is perhaps not the most prominent reason for the massive interest in this modest-sized tissue residing inside the brain ventricles. Most likely, the dominant reason for extensive studies of the choroid plexus is the identification of this epithelium as the source of the majority of intraventricular cerebrospin...

background: except in emergency cases, all patients should be seen first by a primary healthcare physician who decides whether a referral to secondary care is necessary. the present study examined the reasons for patient self-referral to specialists. methods: a random sample of 1036 individuals was selected from people attending public outpatient clinics and specialists’ offices in the private ...

proportionating system was dismantled and a gas leak found in the Cambridge Bourdon tube type dialysate temperature gauge which caused the needle pointer to register about 20'C too low. The fault had come on over a period of time and, unfortunately, it had been assumed that the Cambridge gauge was indicating the true dialysate temperature. Therefore the back-up temperature alarm system and the ...

Peritoneal dialysis can be considered a "wearable" dialysis therapy. However, patients typically require 3 or 4 daily exchanges, each taking 20-40 minutes and potentially increasing the risk of infection by repeated disconnection and reconnection. Although peritoneal dialysis cyclers allow patients to be "free" from their machine for 13-15 hours, they similarly need a supply of fresh dialysate....

Abstract Background: Convulsion in neonatal period is a considerable clinical issue because of its potential brain damage.One of the benign neonatal seizures known as the  fifth day fits ,is due to zinc deficiency. Zinc is a rare element which has spread throughout the body fluids and tissues especially central nervous system. Reduction of neurons’ stimulation has been ascribed as the main eff...
