Background Despite rapid dissemination of an everolimus-eluting bioresorbable scaffold for treatment for coronary artery disease, no data from comparisons with its metallic stent counterpart are available. In a randomised controlled trial we aimed to compare an everolimus-eluting bioresorbable scaffold with an everolimus-eluting metallic stent. Here we report secondary clinical and procedural outcomes after 1 year of follow-up. Methods In a single-blind, multicentre, randomised trial, we enrolled eligible patients aged 18-85 years with evidence of myocardial ischaemia and one or two de-novo native lesions in different epicardial vessels. We randomly assigned patients in a 2:1 ratio to receive treatment with an everolimus-eluting bioresorbable scaffold (Absorb, Abbott Vascular, Santa Clara, CA, USA) or treatment with an everolimus-eluting metallic stent (Xience, Abbott Vascular, Santa Clara, CA, USA). Randomisation was stratified by diabetes status and number of planned target lesions. The co-primary endpoints of this study are vasomotion (change in mean lumen diameter before and after nitrate administration at 3 years) and difference between minimum lumen diameter (after nitrate administration) after the index procedure and at 3 years. Secondary endpoints were procedural performance assessed by quantitative angiography and intravascular ultrasound; composite clinical endpoints based on death, myocardial infarction, and coronary revascularisation; device and procedural success; and angina status assessed by the Seattle Angina Questionnaire and exercise testing at 6 and 12 months. Cumulative angina rate based on adverse event reporting was analysed post hoc. This trial is registered at ClinicalTrials.gov, number NCT01425281. Findings Between Nov 28, 2011, and June 4, 2013, we enrolled 501 patients and randomly assigned them to the bioresorbable scaffold group (335 patients, 364 lesions) or the metallic stent group (166 patients, 182 lesions). Dilatation pressure and balloon diameter at the highest pressure during implantation or postdilatation were higher and larger in the metallic stent group, whereas the acute recoil post implantation was similar (0·19 mm for both, p=0·85). Acute lumen gain was lower for the bioresorbable scaffold by quantitative coronary angiography (1·15 mm vs 1·46 mm, p<0·0001) and quantitative intravascular ultrasound (2·85 mm2 vs 3·60 mm2, p<0·0001), resulting in a smaller lumen diameter or area post procedure. At 1 year, however, cumulative rates of first new or worsening angina from adverse event reporting were lower (72 patients [22%] in the bioresorbable scaffold group vs 50 [30%] in the metallic stent group, p=0·04), whereas performance during maximum exercise and angina status by SAQ were similar. The 1-year composite device orientated endpoint was similar between the bioresorbable scaffold and metallic stent groups (16 patients [5%] vs five patients [3%], p=0·35). Three patients in the bioresorbable scaffold group had definite or probable scaffold thromboses (one definite acute, one definite sub-acute, and one probable late), compared with no patients in the metallic stent group. There were 17 (5%) major cardiac adverse events in the bioresorbable scaffold group compared with five (3%) events in the metallic stent group, with the most common adverse events being myocardial infarction (15 cases [4%] vs two cases [1%], respectively) and clinically indicated target-lesion revascularisation (four cases [1%] vs three cases [2%], respectively). Interpretation The everolimus-eluting bioresorbable scaffold showed similar 1-year composite secondary clinical outcomes to the everolimus-eluting metallic stent.

Background Although maintenance bacillus Calmette-Guérin (BCG) is the recommended treatment in high-risk non-muscle-invasive bladder cancer (NMIBC), its efficacy in older patients is controversial. Objective To determine the effect of age on prognosis and treatment outcome in patients with stage Ta T1 NMIBC treated with maintenance BCG. Design, setting, and participants A total of 957 patients with intermediate- or high-risk Ta T1 (without carcinoma in situ) NMIBC were randomized in European Organization for Research and Treatment of Cancer (EORTC) trial 30911 comparing six weekly instillations of epirubicin, BCG, and BCG plus isoniazid followed by three weekly maintenance instillations over 3 yr. Outcome measurements and statistical analysis Cox multivariate proportional hazards regression models were used to assess the relative importance of age for recurrence, progression, overall survival, and NMIBC-specific survival with adjustment for EORTC risk scores. Results and limitations Overall, 822 eligible patients were included: 546 patients in the BCG with or without INH arms and 276 in the epirubicin arm. In patients treated with BCG with or without INH, 34.1% were >70 yr of age and 3.7% were >80 yr. With a median follow-up of 9.2 yr, patients >70 yr had a shorter time to progression (p = 0.028), overall survival (p < 0.001), and NMIBC-specific survival (p = 0.049) after adjustment for EORTC risk scores in the multivariate analysis. The time to recurrence was similar compared with the younger patients. BCG was more effective than epirubicin for all four end points considered, and there was no evidence that BCG was any less effective compared with epirubicin in patients >70 yr. Conclusions In intermediate- and high-risk Ta T1 urothelial bladder cancer patients treated with BCG, patients >70 yr of age have a worse long-term prognosis; however, BCG is more effective than epirubicin independent of patient age. Patient summary Intravesical bacillus Calmette-Guérin for non-muscle-invasive bladder cancer is less effective in patients >70 yr of age, but it is still more effective than epirubicin. © 2014 European Association of Urology.

Purpose: In the recent clinical guideline for acute lateral ankle sprain, the current best evidence for diagnosis, treatment and prevention strategies was evaluated. Key findings for treatment included the use of ice and compression in the initial phase of treatment, in combination with rest and elevation. A short period of taking non-steroidal anti-inflammatory drugs (NSAIDs) may facilitate a rapid decrease in pain and swelling can also be helpful in the acute phase. The objective was to assess the effectiveness and safety of oral and topical NSAID in the treatment for acute ankle sprains. Methods: Randomised controlled trials comparing oral or topic NSAID treatment with placebo or each other were included. Primary outcome measures were pain at rest or at mobilisation and adverse events. Trials were assessed using the Cochrane risk of bias tool. Results: Twenty-eight studies were included, and 22 were available for meta-analysis. Superior results were reported for oral NSAIDs when compared with placebo, concerning pain on weight bearing on short term, pain at rest on the short term, and less swelling on short- and intermediate term. For topical NSAIDs, superior results compared with placebo were found for pain at rest (short term), persistent pain (intermediate term), pain on weight bearing (short- and intermediate term) and for swelling (short and intermediate term). No trials were included comparing oral with topic NSAIDs, so conclusions regarding this comparison are not realistic. Conclusions: The current evidence is limited due to the low number of studies, lack of methodological quality of the included studies as well as the small sample size of the included studies. Nevertheless, the findings from this review support the use of NSAIDs for the initial treatment for acute ankle sprains.

This case report describes a 38-year-old woman in whom a primary caesarean section for placenta previa was complicated by postpartum haemorrhage due to a placenta accreta. Despite tamponade with a Bakri balloon and placement of a B-Lynch suture, the amount of blood loss could not be effectively reduced. The blood loss was eventually minimised by the placement of a Penrose drain around the cervix as a cervical tourniquet. We think that a cervical tourniquet is an effective method of stopping haemorrhage during caesarean section, as shown in this case report, and we consider this technique to be a valuable addition to several existing methods through which fertility is preserved by preventing emergency hysterectomy.

The objective of this article is to systematically review the currently available literature to formulate evidence-based guidelines for the treatment of femoral shaft nonunions for clinical practice and to establish recommendations for future research. Articles from PubMed/MEDLINE, Cochrane Clinical Trial Register, and EMBASE, that presented data concerning treatment of nonunions of femoral shaft fractures in adult humans, were included for data extraction and analysis. The search was restricted to articles from January 1970 to March 2011 written in the English, German, or Dutch languages. Articles containing data that were thought to have been presented previously were used once. Reports on nonunion after periprosthetic fractures, review articles, expert opinions, abstracts from scientific meetings, and case reports on 5 or fewer patients were excluded. The data that were extracted from the relevant articles included: type of nonunion, type of initial and secondary treatments, follow-up, union rate, and general complications. Most studies had different inclusion criteria and outcome measures, thus prohibiting a proper meta-analysis. Therefore, only the union rate and number of complications were compared between the different treatments. Methodological quality was assessed by assigning levels of evidence as previously defined by the Centre for Evidence-Based Medicine. This systematic review provides evidence in favour of plating if a nail is the first treatment; after failed plate fixation, nailing has a 96 % union rate. After failed nailing, augmentative plating results in a 96 % union rate compared to 73 % in the exchange nailing group. © 2013 The Author(s). Source
