Selected AbstractsDrug-Eluting Stents Versus Bare Metal Stents Following Rotational Atherectomy for Heavily Calcified Coronary Lesions: Late Angiographic and Clinical Follow-Up ResultsJOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 2 2007AHMED A. KHATTAB M.D. Objectives: To study the effectiveness of drug-eluting stents following rotablation of severely calcified lesions. Background: Drug-eluting stents are increasingly showing promising results in complex lesions and high-risk patients. Heavily calcified stenoses have not been adequately studied, and form a challenge both for the immediate and late outcomes. Methods: Single-center prospective study among 27 patients treated by rotablation followed by a drug-eluting stent implantation for angiographically heavily calcified lesions, compared with a historical control of 34 patients treated by rotablation followed by bare stent implantation for the same indication. The primary endpoint was the late lumen loss at 9 months; secondary endpoints were binary restenosis and major adverse cardiac events at 9 months. A 2-year follow-up directed to death and myocardial infarction was added. Results: Both groups were comparable regarding baseline and procedural characteristics. Angiographic success was 100% for both groups. At 9 months, there was a significant difference in the late lumen loss (0.11 ± 0.7 mm in the DES group and 1.11 ± 0.9 mm in the BMS group, P = 0.001). This difference was manifest in the clinical event rates at late follow-up (combined incidence of death due to any cause, MI, and TLR was 7.4% in the DES group and 38.2% in the BMS group; P = 0.004). At 2 years, there were 5 deaths in each group (P = 0.5) and 2 infarctions in the BMS group versus none in the DES group (P = 1.0). Conclusion: The combination of rotablation and drug-eluting stent implantation (Rota-DES) has a favorable effect on clinical and angiographic outcomes at 9 months when treating heavily calcified lesions compared to rotablation followed by bare metal stent implantation. No safety concerns are observed at 2 years. [source] Comparative immunogenicity of recombinant B domain-deleted porcine factor VIII and Hyate:C in hemophilia A mice presensitized to human factor VIIIJOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 4 2004E. T. Parker Summary., Hyate is a commercial plasma-derived porcine factor (F)VIII concentrate that is used in the treatment of patients with inhibitory antibodies to FVIII. OBI-1 is a recombinant B domain-deleted form of porcine FVIII that is in clinical development for the same indication. Hemophilia A mice were presensitized with human FVIII to simulate clinical inhibitory antibody formation and then were randomized to receive OBI-1 or Hyate:C in a comparative immunogenicity trial. OBI-1 or Hyate:C were given in a series of four intravenous injections at weekly intervals at doses of 1, 10, or 100 U kg,1. Inhibitory antibodies to porcine FVIII were not detected by Bethesda assay in most of the mice given OBI-1 or Hyate:C at doses of 1 or 10 U kg,1, but were identified in 81% and 94% of mice given 100 U kg,1 of OBI-1 or Hyate:C, respectively. There was no significant difference between OBI-1 and Hyate:C in inhibitory antibody formation at any dose, although there was a trend toward a lower Bethesda titer in OBI-1-treated mice at 10 U kg,1 (P = 0.09). Total anti-FVIII antibodies to Hyate:C and OBI-1 were also measured by ELISA using immobilized purified plasma-derived porcine FVIII and OBI-1, respectively, as antigens. At the 10 and 100 U kg,1 doses, the mean anti-FVIII response was higher in Hyate:C-treated-mice than in OBI-1-treated mice (P = 0.02 and P = 0.004, respectively). The results using this model suggest that OBI-1 may be less immunogenic and safer than Hyate:C in FVIII inhibitor patients. [source] Domperidone versus cisapride in the treatment of infant regurgitation and increased acid gastro-oesophageal reflux: a pilot studyACTA PAEDIATRICA, Issue 4 2009Badriul Hegar Abstract Aim: Although domperidone is used frequently to treat infant regurgitation, efficacy data are scarce. Cisapride was previously used in the same indication. Methods: Domperidone and cisapride were compared in an investigator-blinded, prospective comparative trial by evaluating (a) the frequency of regurgitation, (b) acid reflux and (c) cardiac side effects in infants regurgitating >4 times/day since >2 weeks and with reflux-associated symptoms of discomfort, after conservative treatment failure. Results: Within the first treatment week, the frequency of regurgitation decreased in both groups, more rapidly in the cisapride group: the median regurgitation decreased from 6.22 to 3.50 in the cisapride group versus from 4.80 to 3.70 in the domperidone group. The decrease in regurgitation was still significant after 1 month: cisapride from 6.22 to 1.55 versus domperidone from 4.80 to 1.25. However, the natural decrease in the incidence of regurgitation induced by age should also be considered. The median reflux index decreased after 1 month in the cisapride group from 3.60 to 1.75 versus from 2.70 to 2.45 in the domperidone group. One child treated with cisapride developed a significant QT prolongation. Conclusion: The decrease in regurgitation was comparable in both groups, although acid reflux decreased more in the cisapride group. Cisapride induced QT prolongation in one infant.

Montalti Montalti R, Rompianesi G, Di Benedetto F, Ballarin R, Gerring RC, Busani S, De Pietri L, De Ruvo N, Iemmolo RM, Guerrini GP, Smerieri N, Gerunda GE. Liver transplantation in patients aged 65 and over: a case,control study. Clin Transplant 2010 DOI: 10.1111/j.1399-0012.2010.01230.x. © 2010 John Wiley & Sons A/S. Abstract:, Introduction:, The average age of patients undergoing liver transplantation (LT) is consistently increasing. The aim of this case,control study is to evaluate survival and outcome of patients ,65 yr compared to younger patients undergoing LT. Materials and methods:, From 10/00 to 4/08 we performed 330 primary LT, 31 (9.4%) of these were in patients aged 65,70. Following a case,control approach, we compared these patients with 31 patients aged between 41 and 64 yr and matched according to sex, LT indication, viral status, cadaveric/living donor, LT timing, and Model for End-Stage Liver Disease (MELD) score. Results:, There were no statistically significant differences in demographic and surgical donor characteristics. The mean MELD score was under 18 in both groups. Post-LT complications occurred with a similar incidence in the two groups. one-, three-, and five-yr survival was 83.9%, 80.6%, and 80.6%, respectively, for the elderly group, and 80.6%, 73.8%, and 73.8%, respectively, for the young group (p = 0.61). Discussion:, Patients aged between 65 and 70 with low MELD score who undergo LT have the same short- and middle-term survival expectancy, morbidity, and outcome quality as younger patients with the same indication and same pre-LT pathology severity, whatever they might be. Thus, chronological age alone should not deter LT workup in patients >65 and <70. [source] First trimester exposure to cefuroxime: a prospective cohort studyBRITISH JOURNAL OF CLINICAL PHARMACOLOGY, Issue 2 2000Matitiahu Berkovitch Aims There are no published studies on the safety of cefuroxime use during pregnancy. We therefore investigated prospectively the possible teratogenic effect of intrauterine exposure to cefuroxime. Methods One hundred and six women who received cefuroxime during the first trimester of pregnancy were recruited from three teratogen information centres in Israel. Exposed women were paired for age, smoking habits and alcohol consumption with references being exposed to nonteratogenic antibiotics administered for the same indications. Results Maternal history, birthweight, gestational age at delivery, rates of live births, spontaneous abortions and fetal distress were comparable among the two groups. Rates of major malformations in the cefuroxime group (3.2%) did not differ from references (2%) (P = 0.61, relative risk = 1.56, 95% confidence interval 0.27,9.15). There was a significantly higher rate of induced abortions among the cefuroxime exposed women as compared to the references (P = 0.04, relative risk = 3.33, 95% confidence interval 0.94,11.77). Conclusions Our data may suggest that exposure to cefuroxime during the first trimester is probably not associated with an increased risk for malformations or spontaneous abortions; however, in light of the small sample size and the broad confidence limits, larger studies are needed to confirm these findings.
