Introduction Transposed basilic vein arteriovenous fistulas suffer from stenosis at their basilic angle of transposition (BAT). This lesion exhibits frequent recurrence after angioplasty. The primary goal of this study was to determine the effect of stent-graft placement on BAT lesion- and access-patency. The secondary goals were to determine the frequency of intervention pre- and post-stent placement and stent-associated stenosis.Methods Thirty-seven cases had stent-grafts placed at their BAT to manage stenosis. Cases served as their own controls by analyzing their lesion- and access-patency pre- and post-stent placement. Student's t-test was used for analysis of continuous variables. Categorical variables were evaluated by Fisher's exact test. Tests were considered significant when p was =0.05.Results At 6 and 12 months, pre-stent lesion primary patency rates were 29% and 3%, and post-stent were 57% and 40%, respectively. Lesion primary assisted patency rates were 39% and 13%, and post-stent were 91% and 80%, respectively. At 6 and 12 months, pre-stent access primary patency rates were 29% and 3%, and post-stent were 26% and 19%, respectively. Pre-stent primary access assisted patency rates were 36% and 10%, and post-stent were 82% and 75%, respectively. Lesion intervention rates averaged 0.47/month pre-stent and 0.13/month post-stent. Access intervention rate averaged 0.50/month pre-stent, and 0.15/month post-stent. Stent-associated stenosis was seen in 23 cases.Conclusions Treatment of BAT stenosis with stent-grafts had positive impact on the target lesion and the dialysis access circuit.

Daclizumab can decrease the incidence of acute rejection (AR) in renal transplant (RTx) recipients. In this prospective study, 52 RTx patients were divided into two groups according to the dose of daclizumab: 1 mg/kg on day 0 and every 14 days for five doses (group 1, n30) or a truncated regimen of 2 mg/kg on day 0 and on the day of discharge (group 2, n22). The following variables were recorded: demographics; delayed graft function; AR at 3, 6, and 12 months; time to AR; chronic allograft nephropathy (CAN); and serum creatinine. The overall incidences of AR were 23% and 27% (P0.76) in groups 1 and 2, respectively, whereas at 6 months they were 21% and 18% (P1.0). Median time to AR was 10 days in group 1 and 94 days in group 2 (P0.09). The incidence of CAN was 6.6% in group 1 and 13% in group 2 (P0.63). These data suggest that the truncated dose of daclizumab is as effective as the standard regimen for AR prophylaxis.

A crystalline cubic ammonium molybdate (CAM) was synthesized by the reaction of hexaammonium heptamolybdate and HNO3at 60 °C. The X-ray diffraction pattern showed a body-centered cubic structure with crystal lattice of 12.94±0.005 Å. Ammonia free molybdic acid was not obtained even at high acid concentration. CAM contains both exchangeable and structural ammonium ions. On the basis of chemical and thermal analyses and amount of exchangeable H+, the empirical formula of the H+form of CAM referred to [H0.68(NH4)2]O1.34·14.16MoO3·6.92H2O. CAM was found to be stable at relatively high acid concentration and temperature, and was suitable for column operations by grading to the desired mesh size.

The alkali metal ion exchange reaction on cubic ammonium molybdate (CAM) cation exchanger was studied in acidic as well as alkaline media. The ion-exchange reaction and TPD-Mass thermogram of CAM indicated the presence of structural NH4+as interstitial solid solution. The stuctural NH4+in the H+form of CAM (H-CAM) was efficiently exchanged with K+as compared with other alkali metal ions in the equilibrated solutions. The exchanger was observed to be stable in acid medium, however structural transformations were observed at high pH. The presence of K+and Cs+at high pH could act as “Structure Building Ions” for CAM or H-CAM.

The ion-exchange selectivity of H+-form of cubic ammonium molybdate (H-CAM) was studied for alkali metal ions in both HNO3and NH4NO3media. Ideal ion-exchange reaction was observed in both the media with high selectivity for Rb+and Cs+. The selectivity sequence was found to be Li+

Difluoroethane is the active ingredient in various computer cleaners and is increasingly abused by teenagers due to its ease of access, quick onset of euphoric effects, and lack of detectability on current urine drug screens. The substance has detrimental effects on various organ systems; however, its effects on the kidneys remain largely unreported. The following case report adds new information to the developing topic of acute kidney injury in patients abusing difluoroethane inhalants. In addition, it is one of the first to show a possible relationship between prolonged difluoroethane abuse and the development of chronic kidney disease in the absence of other predisposing risk factors.
