The aim of the work was to develop and to evaluate the clinical efficiency of a mobile telecare system implementing teleconsultations based on the continuous transmission of patient-collected data directly to the physician and to the clinic. The developed TeleMed system consists of the patients' and the diabetologist's mobile units, the diabetologist's clinic and home workstations and the clinical server. The evaluation of the system was performed on a group of 13 newly diagnosed type 1 diabetic patients, during a single-arm study with 3-days run-in period, including a one-day intensive educational program, and 3-week study period, when the intensive insulin treatment was conducted without visits of patients to the clinic. ⋯ The TeleMed facilitates not only efficient realization of the intensive insulin treatment but also successful remote patient training and education. No formal patient satisfaction study was done. However, some of the findings indicate that the application of the developed system increases patient self-confidence and quality of life.

Renal itch is a localized or generalized itch, affecting patients with Chronic Renal Failure, where there is no primary skin disease and no systemic or psychological dysfunction that might cause pruritus. Uremic pruritus (UP) is an unpleasant sensation, rarely appearing in earlier stages of chronic kidney disease. Renal transplantation is the definite solution for that problem. ⋯ During the last decades a big number of substances were considered to be etiologic factors of UP, and an even bigger number of therapeutic substances appeared with promising potentials and conflicting results in the course of their use. The main reason for this disorientation is the lack of sound evidence on the pathogenetic mechanisms that may potentiate UP. 'Inflammatory' and 'opioid' hypothesis are the best studied and the reduction of UP is a fact. Nevertheless the mechanisms of the pathogenesis of UP are still under investigation and a long way has to be done in order to achieve more definite results.

Since the last decade, hemofiltration and especially high volume hemofiltration has rapidly evolved from a somewhat experimental treatment towards a potentially effective 'adjunctive' therapy in severe septic shock and especially refractory or catecholamine resistant hypodynamic septic shock. Nevertheless, this approach lacks prospective randomized studies (PRT'S) evaluating the critical role of early hemofiltration in sepsis. An important step forward which could be called the 'big bang' in term of hemofiltration was the publication of a PRT in patients with acute renal failure (ARF) (1). ⋯ On top of the use of early and adequate dose of hemofiltration in sepsis, a higher dose could also provide better renal recovery rate and reduce the risk of associate chronic dialysis in these patients. Furthermore, this paper also reviews 'brand' new theories regarding the rationale for hemofiltration in sepsis. Finally, this paper also addresses the so-called negative studies as well anticipated side effects.

Continuous renal replacement therapy (CRRT) affects acid-base balance but the influence of severe hepatic failure (SHF) on this effect is unknown. ⋯ The use of CVVH does not fully correct the independent acidifying effect of liver failure on acid-base status. Increased lactate and strong ion gap values maintain a persistent base deficit despite the alkalinizing effects of hypoalbuminemia and hypochloremia. The correction of acidosis in SHF patients may require more intensive CVVH.

Comparative Study Clinical Trial
Safety of citrate based hemofiltration in critically ill patients at high risk for bleeding: a comparison with nadroparin.
To study the incidence and severity of bleeding in high risk critically ill patients during high volume, citrate based continuous veno-venous hemofiltration (CVVH). ⋯ In high risk critically ill patients citrate based anticoagulation for CVVH is safe in terms of bleeding complications and transfusion requirements.
