Aim The aim of this systematic review was to evaluate the efficacy of anti-plaque chemical formulations for managing gingivitis, in 6-month, home-use, randomised clinical trials ( RCTs). Material and Methods A protocol was designed, including inclusion and exclusion criteria to identify RCTs assessing gingival and/or bleeding indices. Electronic and hand-searches identified relevant papers, which were screened and evaluated for inclusion. Full-papers were retrieved and relevant information was extracted (also plaque indices), including quality and risk of bias. Mean treatment effects were calculated to obtain weighted mean differences ( WMD) and 95% confidence intervals. Results After the process of screening and selection, 87 articles with 133 comparisons, were included in the review. The additional effects of the tested products were statistically significant in terms of Löe & Silness gingival index (46 comparisons, WMD −0.217), modified gingival index ( n = 23, −0.415), gingivitis severity index ( n = 26, −14.939%) or bleeding index ( n = 23, −7.626%), with significant heterogeneity. For plaque, additional effects were found for Turesky (66 studies, WMD −0.475), Silness & Löe ( n = 26, −0.109), and plaque severity ( n = 12, −23.4%) indices, with significant heterogeneity. Conclusion Within the limitations of the present study, formulations with specific agents for chemical plaque control provide statistically significant improvements in terms of gingival, bleeding and plaque indices.

Aim To report the evidence on the effect of mechanical and/or chemical plaque control in the simultaneous management of gingivitis and caries. Material and Methods A protocol was designed to identify randomized ( RCTs) and controlled ( CCTs) clinical trials, cohort studies and prospective case series ( PCS), with at least 6 months of follow-up, reporting on plaque, gingivitis and caries. Relevant information was extracted from full papers, including quality and risk of bias. Meta-analyses were performed whenever possible. Results After the screening of 1,373 titles, 15 RCTs, 10 CCTs and 2 PCS were included. Low to moderate evidence support that combined professional and self-performed mechanical plaque control significantly reduces standardized plaque index [ n = 4; weighted mean difference ( WMD) = 1.294; 95% CI (0.445; 2.144); p = 0.003] and gingivitis scores [ n = 4; WMD = 1.728; 95% CI (0.631; 2.825); p = 0.002]. The addition of fluoride to mechanical plaque control is relevant for caries management [ n = 5; WMD = 1.159; 95% CI (0.145; 2.172); p = 0.025] while chlorhexidine rinses are relevant for gingivitis. Conclusion Mechanical plaque control procedures are effective in reducing plaque and gingivitis. The addition of fluoride to mechanical plaque control is significant for caries management. Chlorhexidine rinse has a positive effect on gingivitis and inconclusive role in caries. [ABSTRACT FROM AUTHOR]

Background Central venous catheters (CVCs) facilitate the administration of intravenous drugs, fluids, blood products and parenteral nutrition to patients with either chronic disease or critical illness. Despite a pivotal role within medical management, a common complication associated with CVC use is occlusion of the CVC lumen(s). CVC occlusion can interrupt and cause serious delays in administration of treatment interventions. Objectives The primary objective of this review was to assess the efficacy and safety of different interventions used to restore patency of occluded CVC lumens, in adults and children. Search methods We identified trials by searching the Cochrane Central Register of Clinical Trials (CENTRAL) ( The Cochrane Library 2011, Issue 9); OvidSP MEDLINE (1950 to September 2011); OvidSP EMBASE (1980 to September 2011) and NHS Evidence CINAHL (1982 to September 2011). We also searched clinical trial registers, handsearched reference lists, contacted pharmaceutical companies and authors of publications that met the inclusion criteria to identify trials. Selection criteria We selected randomized controlled trials which investigated the efficacy of an intervention (chemical, surgical or drug) used to restore patency to an occluded CVC lumen, in either adults or children. Data collection and analysis Three authors independently assessed those studies that met the inclusion criteria for quality and extracted the relevant data using a standardized form. Main results No studies were found that investigated the efficacy and safety of either chemical or surgical interventions. Seven studies (eight papers) with a total of 632 participants were identified from the search. They investigated different comparisons, strengths of thrombolytic or anticoagulant drug interventions for treating CVC lumen occlusion thought to be caused by a thrombus. There was low quality evidence from a meta-analysis of two studies suggesting that urokinase (various strengths) was more effective than placebo for restoring patency to occluded CVC lumens in adults and children with underlying medical conditions (relative risk (RR) 2.09, 95% confidence interval (CI) 1.47 to 2.95), with a number needed to treat of 4 (95% CI 2 to 8). There was insufficient evidence to draw conclusions on the safety of urokinase. The overall quality of the evidence provided by these studies was low to very low due to one or more domains being assessed as either at 'unclear risk of bias' or 'high risk of bias'. Furthermore, the total number of participants in these studies was small and consequently may lead to spurious results. Authors' conclusions There is inadequate evidence to draw strong conclusions on the efficacy or safety of the drug interventions included in this review. There is some low quality evidence from a meta-analysis of two studies investigating urokinase (various strengths) and some very low evidence from two single studies investigating alteplase 2 mg/2 mL that suggest that these two drug interventions may be effective in treating withdrawal or total occlusion of CVC lumens caused by thrombosis. Further high quality, sufficiently powered research is still required to look at the efficacy and safety of urokinase, alteplase and other chemical, surgical and drug interventions for treating CVC lumen occlusion. Research studies which exclusively include child participants are especially warranted. Plain Language Summary Interventions for restoring patency of occluded central venous catheter lumens A central venous catheter is a small, hollow tube that is inserted into a large vein in either the chest, neck or groin. Central venous catheters enable healthcare professionals to administer drugs and other fluids directly into the blood stream, in order to treat critically ill patients or those patients with a long-term condition. In certain chronic conditions, patients or their carers may also be involved with the administration of treatment interventions via the central venous catheter. Occasionally, the catheter lumens can become blocked with either a blood clot or a treatment intervention solidifying in the tube, or due to the position of the tube inside the vein. If the catheter does become blocked it may mean that the patient has to undergo further surgery to remove and replace the blocked catheter. No studies were found investigating the efficacy and safety of surgical interventions (brush, snare or guidewire exchange) or chemical interventions (hydrochloric acid, sodium bicarbonate, 70% ethanol solution) to unblock the catheter. Our search identified seven studies (eight papers), with a total of 632 participants, that investigated different drug comparisons or compared different strengths of drug therapies for treating catheters that were either completely or partially blocked with a blood clot. This review has found low to very low quality evidence suggesting that thrombolytic drugs (urokinase and alteplase) could be effective in unblocking central venous catheter lumens blocked by blood clots. However, the total number of participants included in these trials was small and consequently the results of the analysis may well be over exaggerated. There were also issues with the way the studies were conducted that could possibly have introduced bias. In conclusion, more research is required to establish the efficacy and safety of different treatment interventions used to unblock occluded central venous catheter lumens. Particularly, there is a need for studies exclusively in children. [ABSTRACT FROM AUTHOR]

Background Despite harmful drinking causing a significant burden on global health, there is a large treatment gap, especially in low- and middle-income countries. A major barrier to care is the lack of adequately skilled human resources to deliver contextually appropriate treatments. This paper describes the systematic process used to develop Counselling for Alcohol Problems ( CAP), a brief psychological treatment (PT) for delivery by lay counselors in routine primary care settings to men with harmful drinking in India. Methods CAP was developed using a methodology involving 3 sequential steps: (i) identifying potential treatment strategies; (ii) developing a theoretical framework for the treatment; and (iii) evaluating the acceptability and feasibility of the treatment. Results CAP is a 3-phase treatment delivered over 1 to 4 sessions based on a motivational interviewing ( MI) stance and involves the following strategies: assessment and personalized feedback, family engagement, drink refusal skills, skills to address drinking urges, problem-solving skills and handling difficult emotions, and relapse prevention and management. Data from a case series were used to inform several adaptations to enhance the acceptability of CAP to the recipients and feasibility of delivery by lay counselors of the treatment, for example expansion of the target group to include alcohol-dependent patients and the extension of the delivery settings to include home-based delivery. There was preliminary evidence of the effectiveness of CAP. Conclusions CAP is an acceptable brief PT for harmful drinking delivered by lay counselors in primary care whose effectiveness is currently being tested in a randomized controlled trial based in primary care in Goa, India.

Purpose To assess the efficacy of petrolatum jelly for the prevention of diaper rash and to evaluate the relationship between the occurrence of diaper rash and certain treatments and type of nutrition. Design and Methods A randomized clinical trial was carried out with two parallel groups ( n = 213) at the neonatal care unit of Donostia University Hospital in San Sebastián, Guipuzcoa Province, Spain. Results There was a lower incidence of diaper rash in the experimental group with petrolatum jelly (17.1%) than the control group (22.2%), but the difference was not statistically significant ( p =.39). The use of antibiotics and oral 50% glucose as well as an increased number of stools are associated with a higher incidence of diaper rash, while breastfeeding and phototherapy are protective factors. Practice Implications Prevention is strengthened by a better understanding of the risk factors. [ABSTRACT FROM AUTHOR]

Objective: To assess methods, quality and outcomes of systematic reviews (SRs) conducted to evaluate the effectiveness of root coverage (RC) procedures in the treatment of recession-type defects (RTD). Methods: MEDLINE and EMBASE were searched up to and including April 2010 to identify SRs investigating the effectiveness/efficacy of surgical interventions for the treatment of patients with RTD. Searching was conducted independently by two reviewers, and data extraction was based on the methodological criteria applied and on the effects of interventions reported by each SR. The checklist proposed by Glenny and colleagues, the Overview Quality Assessment Questionnaire and the "Assessment of Multiple systematic Reviews", instrument were used to assess the quality of SRs. Additionally, the methodological criteria applied by included reviews were compared with those proposed by the Cochrane Collaboration. Results: Search strategy identified 716 potentially eligible articles, of which 12 papers regarding 10 SRs were included in the study. Results from different SRs showed that subepithelial connective tissue grafts associated or not to coronally advanced flaps can be used to reduce recession depth and improve the width of keratinized tissue. All quality assessment tools showed that most of the SRs were of good methodological quality, but they also highlighted key points that could be improved in future reviews. Only two SRs followed in full the guidelines proposed by the Cochrane Collaboration. Conclusions: All SRs agree that RC may be anticipated by different surgical procedures. However, differences in the methodological quality between reviews were quite evident, and thus making a clear indication that there is a need of standardization of the methods that will be applied by future SRs. As a result, a standardized checklist for reporting SRs was proposed by the authors. [ABSTRACT FROM AUTHOR]

What's known on the subject? and What does the study add? Upper urinary tract transitional cell carcinoma (UUT-TCC) is an aggressive disease. The mainstay in the treatment of UUT-TCC is surgical intervention, with oncological control the primary objective. UUT-TCCs have been conventionally treated with radical nephroureterectomy (NU). This procedure involves removal of the kidney, ureter and ipsilateral excision of a bladder cuff. Whilst open NU has traditionally been the approach used, laparoscopic NU (LNU) is now an increasingly popular and established approach for UUT-TCC. It is argued that LNU reduces postoperative morbidity without compromising oncological efficacy. With technological evolution, robotic NU has now been attempted in some centres as well. In addition, several techniques have been described to manage the bladder cuff with no agreement as to the most efficacious approach. In a further attempt to reduce morbidity and safeguard nephrons, there have been advocates of a number of nephron-sparing techniques, e.g. ureteroscopic management, percutaneous approaches, and distal ureterectomy. These approaches obviously raise concern on oncological efficacy with requirement for more stringent long-term surveillance protocols. This study comprehensively reviews and summarises the evidence comparing various surgical techniques in the management of UUT-TCC. The review additionally evaluates and critically appraises the quality of evidence available, which currently informs practice. Surgical management of upper urinary tract transitional cell carcinoma (UUT-TCC) has significantly changed over the past two decades. Data for several new surgical techniques, including nephron-sparing surgery (NSS), is emerging., The study systematically reviewed the literature comparing (randomised and observational studies) surgical and oncological outcomes for various surgical techniques, MEDLINE, EMBASE, Cochrane Library, CINAHL, British Nursing Index, AMED, LILACS, Web of Science, Scopus, Biosis, TRIP, Biomed Central, Dissertation Abstracts, ISI proceedings, and PubMed were searched to identify suitable studies. Data were extracted from each identified paper independently by two reviewers (B.R. and B.S.) and cross checked by a senior member of the team., The data analysis was performed using the Cochrane software Review manager version 5. Comparable data from each study was combined in a meta-analysis where possible. For dichotomous data, odds ratios with 95% confidence intervals (CIs) were estimated based on the fixed-effects model and according to an intention-to-treat analysis. If the data available were deemed not suitable for a meta-analysis it was described in a narrative fashion., One randomised control trial (RCT) and 19 observational studies comparing open nephroureterectomy (ONU) and laparoscopic NU (LNU) were identified. The RCT reported the LNU group to have statistically significantly less blood loss (104 vs 430 mL, P < 0.001) and mean time to discharge (2.30 vs 3.65 days, P < 0.001) than the ONU group. At a median follow-up of 44 months, the overall 5-year cancer-specific survival (CSS; 89.9 vs 79.8%) and 5-year metastasis-free survival rates (77.4 vs 72.5%) for the ONU were better than for LNU, respectively, although not statistically significant., A meta-analysis of the observational studies favoured LNU group for lower urinary recurrence ( P < 0.001) and distant metastasis. The meta-analyses for local recurrence for the two groups were comparable., One retrospective study comparing ONU with a percutaneous approach for grade 2 disease reported no significant differences in CSS rates (53.8 vs 53.3 months)., Three retrospective studies compared NSS and radical NU, and reported no significant differences in overall CSS and recurrence-free survival between the two approaches., Five retrospective studies compared various techniques of en bloc excision of the lower ureter. No technique was reported to be better (operative and oncological) than any other., This review concludes that there is a paucity of good quality evidence for the various surgical approaches for UUT-TCC. The techniques have been assessed and reported in many retrospective single-centre studies favouring LNU for better perioperative outcomes and comparable oncological safety. The reported observational studies data is further supported by one RCT. [ABSTRACT FROM AUTHOR]
