The peritoneal equilibration test (PET) has been widely used as a standardized means for estimating solute transport. However, the procedure is rather complex, and patients must spend more than half a day in the hospital. The fast PET is an alternative method, but the results are not reliable in patients whose peritoneal catheters drain poorly. We postulated that patients could perform the PET ...

since hospitals are an important and integral part of the overall health delivery system, this study was carried out to measure the effectiveness of this institution within the system. the records of 633 hospitalized patients in the pediatrics ward of ghaem hospital in mashhad during 1357 (21 march 1978-20 march 1979) has been consulted. more than half of the patients were hospitalized with the...

Methods Prospective observational study included patients with septic shock admitted to a Tunisian medical -surgical ICU. Each patient was equipped with an arterial and a central venous catheter; patients were also monitored with a pulmonary artery catheter. Treatment for septic shock was standardized according to international recommendations. Microdialysis(MD) catheter was inserted in the fem...

BACKGROUND In a previous study we demonstrated that mild metabolic alkalosis resulting from standard bicarbonate haemodialysis induces hypotension. In this study, we have further investigated the changes in systemic haemodynamics induced by bicarbonate and calcium, using non-invasive procedures. METHODS In a randomized controlled trial with a single-blind, crossover design, we sequentially ch...

Central prolactin (PRL) modulates neuronal activity, which is physiologically relevant and behaviorally meaningful. The stimulatory or inhibitory behavioral effects of exogenous PRL are strongly associated with dose and time of treatment. Central PRL injections produce a dual modulation of striatal dopaminergic responses in males. The activity of the striatal monoaminergic system can be modulat...

background : identifying the sources of variation in qtc measurements is important for preventing arrhythmias during and after hemodialysis. the present study was designed to determine the correlation between the type of hemodialysis buffer and the changes in qtc interval in patients on chronic hemodialysis.   methods: fifty-nine patients on chronic hemodialysis who referred in winter 2007 to h...

BACKGROUND Fluid and sodium balance is important for the success of long-term peritoneal dialysis. Convective transport is the major determinant for sodium removal during peritoneal dialysis using conventional dialysis solutions. However, recent studies showed that lower sodium concentration in dialysate could significantly increase sodium removal by increasing the diffusion gradient, thereby i...
