    BAC KGROUND: The prominent cause of mortality in children receiving dialysis treatment is cardiovascular diseases. Risk factors related to chronic renal disease, are effective in the development of cardiovascular diseases. The aim of study was to investigate cardiovascular system (CVS) involvement for functional and structural alterations in children receiving dialysis, and display any association between cardiovascular morbidity and uremic toxins. MET HODS: 20 dialysis patients and 20 healthy controls were included to the study. Clearance of small, middle and large molecular-weight uremic toxins was evaluated in blood samples collected 30 minutes before (D0) and 2 hour after dialysis (D2), and change value was calculated as D0-D2/D0. Cardiovascular involvement was determined by comparing arterial stiffness, carotid intima-media thickness (CI MT) and Left Ventricular Mass Index (LVMI) with the control group. RESULTS: Four patients receiving hemodialysis and two patients in continuous ambulatory peritoneal dialysis (CAPD) group who have significant differences in all functional and structural parameters were detected. Four dialysis patients with detected cardiovascular disease have distinctively lower beta-2 microglobulin and homocysteine clearances compared to the patients with no CVS involvement. C ONCLUSIONS: The clearance of middle and large molecular-weight substances should be closely monitored in children receiving dialysis.

    The PMTs of the CMS Hadron Forward calorimeter were found to generate a large size signal when their windows were traversed by energetic charged particles. This signal, which is due to erenkov light production at the PMT window, could interfere with the calorimeter signal and mislead the measurements. In order to find a viable solution to this problem, the response of four different types of PMTs to muons traversing their windows at different orientations is measured at the H2 beam-line at CERN. Certain kinds of PMTs with thinner windows show significantly lower response to direct muon incidence. For the four anode PMT, a simple and powerful algorithm to identify such events and recover the PMT signal using the signals of the quadrants without window hits is also presented. For the measurement of PMT responses to erenkov light, the Hadron Forward calorimeter signal was mimicked by two different setups in electron beams and the PMT performances were compared with each other. Superior performance of particular PMTs was observed. © 2010 IOP Publishing Ltd and SISSA.
