Abstract
OBJECTIVE To assess long-term efficacy and safety of salsalate to improve glycemia in persons with diabetes risk, who are overweight with statin-treated, stable coronary heart disease. METHODS Glycemic status was assessed in 192 persons without diabetes at baseline in a pre-specified secondary analysis from Targeting INflammation Using SALsalate in CardioVascular Disease (TINSAL-CVD), a multi-center, double-masked, randomized (1:1), placebo-controlled, parallel clinical trial. RESULTS Participants were mostly Caucasian males, age 60±7 years, BMI 31.4±3.0 kg/m2 , fasting glucose 92.8±11.0 mg/dL, and HbA1c 5.8±0.3%. Reductions in mean fasting glucose -5.70 mg/dL (95%CI: -7.44 to -3.97 mg/dL, P<0.001), HbA1c -0.11% (95%CI: -0.210 to -0.002%, P=0.046) and glycated serum protein -81.8 μg/mL (95%CI: -93.7 to -69.9 μg/mL, P<0.001) were demonstrated in salsalate compared to placebo-assigned groups over 30 months. Reductions in fasting glucose and glycated serum protein were greater with salsalate compared to placebo in participants with prediabetes compared to a normoglycemic sub-group (Pinteraction =0.018). Salsalate lowered total white blood cell counts (mean difference -0.7x103 /μL, 95%CI: -1.0 to -0.4 x103 /μL, P<0.001) and increased adiponectin (mean difference 1.8 μg/mL, 95%CI: 0.9 to 2.6 μg/mL, P<0.001) and albuminurea (16.7 μg/mg, 95%CI: 6.4 to 27.1 μg/mg, P<0.001) compared to placebo, consistent with previous results for patients with type 2 diabetes taking salsalate for shorter times. CONCLUSIONS Salsalate improves glycemia in obese persons at increased risk for diabetes, and hence may decrease risk of incident type 2 diabetes. Salsalate may inform new therapeutic approaches for diabetes prevention, but renal safety may limit clinical utility.

Abstract
BACKGROUND Lymphocytic colitis is a cause of chronic diarrhea. It is a subtype of microscopic colitis characterized by chronic, watery, non-bloody diarrhea and normal endoscopic and radiologic findings. The etiology of this disorder is unknown.Therapy is based mainly on case series and uncontrolled trials, or by extrapolation of data for treating collagenous colitis, a related disorder. This review is an update of a previously published Cochrane review. OBJECTIVES To evaluate the efficacy and safety of treatments for clinically active lymphocytic colitis. SEARCH METHODS The MEDLINE, PUBMED and EMBASE databases were searched from inception to 11 August 2016 to identify relevant papers. Manual searches from the references of included studies and relevant review articles were performed.Abstracts from major gastroenterological meetings were also searched to identify research submitted in abstract form only. The trial registry web site www.ClinicalTrials.gov was searched to identify registered but unpublished trials. Finally, the Cochrane Central Register of Controlled Trials and the Cochrane Inflammatory Bowel Disease and Functional Bowel Disorders Group Specialized Trials Register were searched for other studies. SELECTION CRITERIA Randomized controlled trials assessing medical therapy for patients with biopsy-proven lymphocytic colitis were considered for inclusion DATA COLLECTION AND ANALYSIS: Data was independently extracted by at least two authors. Any disagreements were resolved by consensus. Data were analyzed on an intention-to-treat (ITT) basis. The primary outcome was clinical response as defined by the included studies. Secondary outcome measures included histological response as defined by the included studies, quality of life as measured by a validated instrument and the occurrence of adverse events. Risk ratios (RR) and 95% confidence intervals (CI) were calculated for dichotomous outcomes. The methodological quality of included studies was evaluated using the Cochrane risk of bias tool. The overall quality of the evidence supporting the primary outcome and selected secondary outcomes was assessed using the GRADE criteria. Data were combined for analysis if they assessed the same treatments. Dichotomous data were combined using a pooled RR along with corresponding 95% CI. A fixed-effect model was used for the pooled analysis. MAIN RESULTS Five RCTs (149 participants) met the inclusion criteria. These studies assessed bismuth subsalicylate versus placebo, budesonide versus placebo, mesalazine versus mesalazine plus cholestyramine and beclometasone dipropionate versus mesalazine. The study which assessed mesalazine versus mesalazine plus cholestyramine and the study which assessed beclometasone dipropionate versus mesalazine were judged to be at high risk of bias due to lack of blinding. The study which compared bismuth subsalicylate versus us placebo was judged as low quality due to a very small sample size and limited data. The other 3 studies were judged to be at low risk of bias. Budesonide (9 mg/day for 6 to 8 weeks) was significantly more effective than placebo for induction of clinical and histological response. Clinical response was noted in 88% of budesonide patients compared to 38% of placebo patients (2 studies; 57 participants; RR 2.03, 95% CI 1.25 to 3.33; GRADE = low). Histological response was noted in 78% of budesonide patients compared to 33% of placebo patients (2 studies; 39 patients; RR 2.44, 95% CI 1.13 to 5.28; GRADE = low). Forty-one patients were enrolled in the study assessing mesalazine (2.4 g/day) versus mesalazine plus cholestyramine (4 g/day). Clinical response was noted in 85% of patients in the mesalazine group compared to 86% of patients in the mesalazine plus cholestyramine group (RR 0.99, 95% CI 0.77 to 1.28; GRADE = low). Five patients were enrolled in the trial studying bismuth subsalicylate (nine 262 mg tablets daily for 8 weeks versus placebo). There were no differences in clinical (P=0.10) or histological responses (P=0.71) in patients treated with bismuth subsalicylate compared with placebo (GRADE = very low). Forty-six patients were enrolled in the trial studying beclometasone dipropionate (5 mg/day or 10 mg/day) versus mesalazine (2.4 g/day). There were no differences in clinical remission at 8 weeks (RR 0.97; 95% CI 0.75 to 1.24; GRADE = low) and 12 months of treatment (RR 1.29; 95% CI 0.40 to 4.18; GRADE = very low). Although patients receiving beclometasone dipropionate (84%) and mesalazine (86%) achieved clinical remission at 8 weeks, it was not maintained at 12 months (26% and 20%, respectively). Adverse events reported in the budesonide studies include nausea, vomiting, neck pain, abdominal pain, hyperhidrosis and headache. Nausea and skin rash were reported as adverse events in the mesalazine study. Adverse events in the beclometasone dipropionate trial include nausea, sleepiness and change of mood. No adverse events were reported in the bismuth subsalicylate study. AUTHORS' CONCLUSIONS Low quality evidence suggests that budesonide may be effective for the treatment of active lymphocytic colitis. This benefit needs to be confirmed by a large placebo -controlled trial. Low quality evidence also suggests that mesalazine with or without cholestyramine and beclometasone dipropionate may be effective for the treatment of lymphocytic colitis, however this needs to be confirmed by large placebo-controlled studies. No conclusions can be made regarding bismuth subsalicylate due to the very small number of patients in the study, Further trials studying interventions for lymphocytic colitis are warranted.

Abstract
INTRODUCTION There is conflicting evidence regarding the efficacy of high dose salicylates in improving cardiometabolic risk in healthy and type 2 diabetes patients. We aimed to determine whether treatment with salicylates at an anti-inflammatory dose (≥1g daily) would improve cardiometabolic risk in healthy individuals and type 2 diabetes patients, compared to placebo. METHODS Medline, Medline-in-process, Embase, and all EBM databases were searched for studies published up to December 2016. Twenty-eight articles from 24 studies comprising 1591 participants were included. Two reviewers independently assessed the risk of bias and extracted data from included studies. Meta-analyses using random-effects model were used to analyze the data. RESULTS High dose salicylates (≥3g/d) decreased fasting glucose (MD -0.4mmol/l, 95% CI -0.54, -0.27) and glucose area under the curve (MD -0.41mmol/l, 95% CI -0.81, -0.01). Salicylates (≥3g/d) also increased fasting insulin (MD 2.4 μU/ml, 95% CI 0.3, 4.4), 2-h insulin (MD 25.4 μU/ml, 95% CI 8.2, 42.6), insulin secretion (MD 79.2, 95% CI 35, 123) but decreased fasting C-peptide (MD -0.11nmol/l, 95% CI -0.2, -0.04), insulin clearance (MD -0.26l/min, 95% CI -0.36, -0.16) and triglycerides (MD -0.36mmol/l, 95% CI -0.51, -0.21) and increased total adiponectin (MD 1.97μg/ml, 95% CI 0.99, 2.95). A lower salicylate dose (1-2.9g) did not change any cardiometabolic parameters (p>0.1). No significant difference was observed between those receiving salicylates and placebo following withdrawal due to adverse events. CONCLUSIONS High dose salicylates appear to improve cardiometabolic risk factors in healthy individuals and type 2 diabetes patients. PROSPERO REGISTRATION NUMBER CRD42015029826.

Abstract
Neuroinflammation plays a critical role in the pathogenesis of traumatic brain injury (TBI). TBI induces rapid activation of astrocytes and microglia, infiltration of peripheral leukocytes, and secretion of inflammatory cytokines. In the context of modest or severe TBI, such inflammation contributes to tissue destruction and permanent brain damage. However, it is clear that the inflammatory response is also necessary to promote post-injury healing. To date, anti-inflammatory therapies, including the broad class of non-steroidal anti-inflammatory drugs (NSAIDs), have met with little success in treatment of TBI, perhaps because these drugs have inhibited both the tissue-damaging and repair-promoting aspects of the inflammatory response, or because inhibition of inflammation alone is insufficient to yield therapeutic benefit. Salsalate is an unacetylated salicylate with long history of use in limiting inflammation. This drug is known to block activation of NF-κB, and recent data suggest that salsalate has a number of additional biological activities, which may also contribute to its efficacy in treatment of human disease. Here, we show that salsalate potently blocks pro-inflammatory gene expression and nitrite secretion by microglia in vitro. Using the controlled cortical impact (CCI) model in mice, we find that salsalate has a broad anti-inflammatory effect on in vivo TBI-induced gene expression, when administered post-injury. Interestingly, salsalate also elevates expression of genes associated with neuroprotection and neurogenesis, including the neuropeptides, oxytocin and thyrotropin releasing hormone. Histological analysis reveals salsalate-dependent decreases in numbers and activation-associated morphological changes in microglia/macrophages, proximal to the injury site. Flow cytometry data show that salsalate changes the kinetics of CCI-induced accumulation of various populations of CD11b-positive myeloid cells in the injured brain. Behavioral assays demonstrate that salsalate treatment promotes significant recovery of function following CCI. These pre-clinical data suggest that salsalate may show promise as a TBI therapy with a multifactorial mechanism of action to enhance functional recovery.

Abstract
OBJECTIVE The aim of this study was to compare the efficacy and safety of 2-week levofloxacin-containing triple therapy, levofloxacin-containing bismuth quadruple therapy, and standard bismuth-containing quadruple therapy as a first-line regimen for the eradication of Helicobacter pylori. METHODS A total of 329 patients with H. pylori infection were randomly divided into 3 groups to receive one of the following regimens: (a) levofloxacin-containing bismuth quadruple therapy, RBAL (rabeprazole 20 mg, b.i.d., bismuth subsalicylate 562 mg, b.i.d., amoxicillin 1 g, b.i.d, levofloxacin 500 mg, once daily), (b) standard bismuth quadruple therapy, RBMT (rabeprazole 20 mg, b.i.d, subsalicylate 562 mg, b.i.d., metronidazole 500 mg, t.i.d, tetracycline 500 mg, q.i.d), or (c) levofloxacin-containing triple therapy, RAL (rabeprazole 20 mg, b.i.d., amoxicillin 1 g, b.i.d, levofloxacin 500 mg, once daily). The primary outcome was the eradication rate in the intention-to-treat (ITT) and per protocol (PP) analysis. RESULTS The eradication rates of the above 3 groups using ITT analysis were RBAL 83.8%, RBMT 88.3%, and RAL 74.8% compared with 91.2, 92.5, and 79.2%, respectively, using PP analysis. The eradication rate using RBMT was significantly higher than that of RAL (p = 0.029 in ITT analysis and p = 0.017 in PP analysis). Several side effects occurred in 156 patients (54.1%) in the RBAL group, 215 (52.3%) in the RBMT group, and 56 (26.2%) in the RAL group (p > 0.05, RBAL vs. RBMT; p < 0.001, RBMT vs. RAL; p < 0.001, RBAL vs. RAL). CONCLUSION All bismuth-containing quadruple therapies had acceptable eradication rates, but levofloxacin-containing triple therapy was not as good as quadruple therapies. Hence, quadruple therapies should be considered the preferred first-line therapy for H. pylori infections.

Abstract
Dental plaque is a biofilm that forms naturally on the surfaces of exposed teeth and other areas of the oral cavity. It is the primary etiological factor for the most frequently occurring oral diseases, such as dental caries and periodontal diseases. Specific, nonspecific, and ecologic plaque hypothesis explains the causation of dental and associated diseases. Adequate control of biofilm accumulation on teeth has been the cornerstone of prevention of periodontitis and dental caries. Mechanical plaque control is the mainstay for prevention of oral diseases, but it requires patient cooperation and motivation; therefore, chemical plaque control agents act as useful adjuvants for achieving the desired results. Hence, it is imperative for the clinicians to update their knowledge in chemical antiplaque agents and other developments for the effective management of plaque biofilm-associated diseases. This article explores the critical analysis of various chemical plaque control strategies and the current trends in the control and prevention of dental plaque biofilm.

Abstract
Traveler's diarrhea (TD) is the most common travel-related illness, and it can have a significant impact on the traveler. Pretravel consultation provides an excellent opportunity for the clinician to counsel the traveler and discuss strategies such as food and water hygiene, vaccinations, and medications for prophylaxis or self-treatment that may decrease the incidence and impact of TD. Postinfectious sequelae, such as postinfectious irritable bowel syndrome, reactive arthritis, and Guillain-Barre syndrome, may develop weeks or months after return.

Abstract
RATIONALE AND AIM The antiplatelet effect of clopidogrel is reportedly influenced by cytochrome P450 2C19 (CYP2C19) polymorphisms. However, there is no data concerning the relationship between stroke recurrence and CYP2C19 polymorphisms in patients treated with clopidogrel for secondary prevention of ischemic stroke. Triflusal may be an alternative therapy for clopidogrel in patients with poor genotype. The Comparison of Triflusal and Clopidogrel Effects in Secondary Prevention of Stroke Based on Cytochrome P450 2C19 Genotyping (MAESTRO) study will investigate the effect of antiplatelet agents based on CYP2C19 polymorphisms in secondary prevention of ischemic stroke. SAMPLE SIZE AND DESIGN Assuming that 55% of patients belong to the poor genotype group, the required sample size is 1080 patients with at least 24 months of follow-up. This study is designed as a prospective, multicenter, randomized, parallel-group, open-label, and blind genotype trial. Patients who experience their first non-cardiogenic ischemic stroke within 30 days prior to screening are eligible. Patients received 300 mg triflusal twice a day or 75 mg clopidogrel once daily during the trial. The study is registered with ClinicalTrials.gov (NCT01174693). STUDY OUTCOME The primary outcome is recurrent ischemic stroke or hemorrhagic stroke. Secondary outcomes consist of composite major vascular events including stroke, myocardial infarction, coronary revascularization, or vascular death. DISCUSSION Personalized medicine may be essential for patients according to individual drug metabolism abilities. MAESTRO is the first prospective study designed to evaluate the effect of CYP2C19 polymorphism in secondary stroke prevention and will resolve several questions regarding preventive antiplatelet agents for recurrent stroke.

Abstract
Objective. Diabetic nephropathy is a life-threatening complication in patients with long-standing diabetes. Hemodynamic, inflammatory, and metabolic factors are considered as developmental factors for diabetic nephropathy. In this study, we evaluated whether pharmacological interventions with salicylate, compared to pyridoxamine, could prevent diabetic nephropathy in mice. Methods. Male mice overexpressing inducible nitric oxide synthase in pancreatic β-cells were employed as a diabetic model. Salicylate (3 g/kg diet) or pyridoxamine (1 g/L drinking water; ~200 mg/kg/day) was given for 16 weeks to assess the development of diabetic nephropathy. Treatment with long-acting insulin (Levemir 2 units/kg twice a day) was used as a control. Results. Although higher blood glucose levels were not significantly affected by pyridoxamine, early to late stage indices of nephropathy were attenuated, including kidney enlargement, albuminuria, and increased serum creatinine, glomerulosclerosis, and inflammatory and profibrotic gene expressions. Salicylate showed beneficial effects on diabetic nephropathy similar to those of pyridoxamine, which include lowering blood glucose levels and inhibiting macrophage infiltration into the kidneys. Attenuation of macrophage infiltration into the kidneys and upregulation of antiglycating enzyme glyoxalase 1 gene expression were found only in the salicylate treatment group. Conclusions. Treatment with salicylate and pyridoxamine could prevent the development of diabetic nephropathy in mice and, therefore, would be a potentially useful therapeutic strategy against kidney problems in patients with diabetes.

Abstract
Microscopic colitis is a common cause of chronic diarrhea. It is characterized by non-bloody watery diarrhea with macroscopically normal colonic mucosa. Its specific histological characteristics confirm the diagnosis. Two distinct histological forms can be identified, namely, collagenous colitis and lymphocytic colitis. In collagenous colitis, a thick colonic subepithelial collagenous deposit can be observed, whereas in lymphocytic colitis, a pronounced intraepithelial lymphocytic inflammation in the absence of a thickened collagen band can be identified. Microscopic colitis occurs more frequently in elderly females and its etiology is believed to be multifactorial, although smoking and consumption of several drugs have been identified as risks factors for the development of the disease. The treatment is based on avoiding the risks factors and administration of oral budesonide.

Abstract
PURPOSE Primary vascular dysregulation (PVD) is a condition in which the response to cold temperature or external stimuli is abnormal. We investigated whether triflusal use results in amelioration of PVD symptoms and improvement of several related parameters compared with aspirin. MATERIALS AND METHODS Eighty-eight PVD patients (54% female, 56±8 years) were randomly selected to receive either triflusal (300 mg, b.i.d.) or aspirin (150 mg, b.i.d.) for a period of 6 weeks followed by crossover. PVD was defined as both red-blood-cell standstill in video-assisted microscopic capillaroscopy during cold stimulation using carbon dioxide gas and a score of more than 7 points in a validated questionnaire. Efficacy of treatment was assessed by 1) cold intolerance symptom severity (CISS) score, 2) finger Doppler indices, and 3) indocyanine green perfusion imaging. RESULTS The use of triflusal resulted in a greater improvement in CISS score (44.5±18.4 vs. 51.9±16.2; p<0.001) and in mean radial peak systolic velocity (69.8±17.2 vs. 66.1±16.4; p=0.011) compared to aspirin. Furthermore, significant differences were also observed in perfusion rates on indocyanine green perfusion imaging between triflusal and aspirin (45.6±25.8 vs. 51.6±26.9; p=0.020). CONCLUSION Triflusal was more effective and demonstrated a more consistent impact on the improvement of symptoms and blood flow in patients with PVD than aspirin.

We conducted a randomised single-blinded clinical trial of 100 cholera patients in Port-au-Prince, Haiti to determine if the probiotic Saccharomyces cerevisiae var. boulardii and the anti-diarrhoeal drug bismuth subsalicylate (BS) were able to reduce the duration and severity of cholera. Subjects received either: S. boulardii 250 mg, S. boulardii 250 mg capsule plus BS 524 mg tablet, BS 524 mg, or two placebo capsules every 6 hours alongside standard treatment for cholera. The length of hospitalisation plus the number and volume of emesis, stool and urine were recorded every 6 hours until the study subject was discharged (n = 83), left against medical advice (n = 11), or requested removal from the study (n = 6). There were no reported deaths or adverse study-related events. There were no statistically significant differences between the study arms and the outcomes of interest.

Abstract
Docosahexaenoic acid (DHA 22:6n-3) and salicylate are both known to exert anti-inflammatory effects. This study investigated the effects of a novel bifunctional drug compound consisting of DHA and salicylate linked together by a small molecule that is stable in plasma but hydrolyzed in the cytoplasm. The components of the bifunctional compound acted synergistically to reduce inflammation mediated via nuclear factor κB in cultured macrophages. Notably, oral administration of the bifunctional compound acted in two distinct ways to mitigate hyperglycemia in high-fat diet-induced insulin resistance. In mice with diet-induced obesity, the compound lowered blood glucose by reducing hepatic insulin resistance. It also had an immediate glucose-lowering effect that was secondary to enhanced glucagon-like peptide-1 (GLP-1) secretion and abrogated by the administration of exendin(9-39), a GLP-1 receptor antagonist. These results suggest that the bifunctional compound could be an effective treatment for individuals with type 2 diabetes and insulin resistance. This strategy could also be employed in other disease conditions characterized by chronic inflammation.

Abstract
BACKGROUND Collagenous colitis (CC) and lymphocytic colitis (LC) are chronic inflammatory disorders of the colon. There is a paucity of data on differences in etiology, natural history, and treatment response between CC and LC. METHODS Between 2002 and 2013, we identified new diagnoses of CC and LC using the Research Patient Data Registry in a tertiary referral center. We used chi square or Fischer's exact test and Wilcoxon rank-sum tests to compare the differences in clinical characteristics, treatment types, and response rates between LC and CC. RESULTS Through 2013, we confirmed 131 patients with a new diagnosis of microscopic colitis (MC) (55 LC, 76 CC). Compared to cases of LC, patients with a diagnosis of CC were more likely to be women (86% vs. 69%, p = 0.03), have elevated erythrocyte sedimentation rate (mean 28 vs. 13 mm/h, p = 0.04), and less likely to be diabetic (5% vs. 18%, p = 0.02). Budesonide was the most effective treatment for both CC and LC (94% and 80%, respectively). However, there were no statistically significant differences in response to various treatments according to the type of MC (all p > 0.10). Older age at the time of diagnosis was associated with better response to bismuth subsalicylate (odds ratio: 1.76; 95% confidence interval: 1.21-2.56 for every 5-year increase) for both CC and LC. CONCLUSION Despite differences in the clinical characteristics, response rates to available treatments appeared to be similar in both LC and CC. Older patients may have a better response to bismuth subsalicylate therapy.

Abstract
INTRODUCTION It is estimated that approximately 30% to 70% of international travellers will develop diarrhoea during their travels or after returning home. METHODS AND OUTCOMES We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute mild-to-moderate diarrhoea in adults from resource-rich countries travelling to resource-poor countries? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2014 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). RESULTS We found 24 studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. CONCLUSIONS In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics (empirical), antibiotics plus antimotility agents, antimotility agents, bismuth subsalicylate, diet, oral rehydration solutions, and racecadotril for travellers' diarrhoea.

Abstract
OBJECTIVES To establish the efficiency and adverse effects of the addition of bismuth subsalicylate to triple eradication therapy for Helicobacter pylori infection. MATERIAL AND METHODS Double blind controlled experimental trial. The study population consisted of 54 patients with Helicobacter pylori infection: 29 were allocated to the experimental group, who received the usual triple plus bismuth subsalicylate therapy, and 24 received the triple therapy plus placebo. RESULTS The average age was 47+-14.9 years, 66.7% of the patients were women. Both groups underwent the breath test: it was negative in 89.7% of the patients from the experimental group and 80% of the patients from the placebo group (p=0.319). The adverse events of both groups were: diarrhea (10.3% in the experimental group vs 16% in the placebo group; p=0.537), dark feces (37.9% in the experimental group vs 0% in the placebo group; p=0.001), abdominal pain (20.7% in the experimental group vs 52% in the placebo group; p=0.016). Nausea only were present in 3% of the patients of placebo group p=0.055). CONCLUSIONS The association of bismuth subsalicylate to the triple therapy scheme for the eradication of Helicobacter pylori was effective in 89.7% of patients, whereas 80% of efficiency in the experimental group.

Abstract
BACKGROUND Tinea infections are fungal infections of the skin caused by dermatophytes. It is estimated that 10% to 20% of the world population is affected by fungal skin infections. Sites of infection vary according to geographical location, the organism involved, and environmental and cultural differences. Both tinea corporis, also referred to as 'ringworm' and tinea cruris or 'jock itch' are conditions frequently seen by primary care doctors and dermatologists. The diagnosis can be made on clinical appearance and can be confirmed by microscopy or culture. A wide range of topical antifungal drugs are used to treat these superficial dermatomycoses, but it is unclear which are the most effective. OBJECTIVES To assess the effects of topical antifungal treatments in tinea cruris and tinea corporis. SEARCH METHODS We searched the following databases up to 13th August 2013: the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library (2013, Issue 7), MEDLINE (from 1946), EMBASE (from 1974), and LILACS (from 1982). We also searched five trials registers, and checked the reference lists of included and excluded studies for further references to relevant randomised controlled trials. We handsearched the journal Mycoses from 1957 to 1990. SELECTION CRITERIA Randomised controlled trials in people with proven dermatophyte infection of the body (tinea corporis) or groin (tinea cruris). DATA COLLECTION AND ANALYSIS Two review authors independently carried out study selection, data extraction, assessment of risk of bias, and analyses. MAIN RESULTS Of the 364 records identified, 129 studies with 18,086 participants met the inclusion criteria. Half of the studies were judged at high risk of bias with the remainder judged at unclear risk. A wide range of different comparisons were evaluated across the 129 studies, 92 in total, with azoles accounting for the majority of the interventions. Treatment duration varied from one week to two months, but in most studies this was two to four weeks. The length of follow-up varied from one week to six months. Sixty-three studies contained no usable or retrievable data mainly due to the lack of separate data for different tinea infections. Mycological and clinical cure were assessed in the majority of studies, along with adverse effects. Less than half of the studies assessed disease relapse, and hardly any of them assessed duration until clinical cure, or participant-judged cure. The quality of the body of evidence was rated as low to very low for the different outcomes.Data for several outcomes for two individual treatments were pooled. Across five studies, significantly higher clinical cure rates were seen in participants treated with terbinafine compared to placebo (risk ratio (RR) 4.51, 95% confidence interval (CI) 3.10 to 6.56, number needed to treat (NNT) 3, 95% CI 2 to 4). The quality of evidence for this outcome was rated as low. Data for mycological cure for terbinafine could not be pooled due to substantial heterogeneity.Mycological cure rates favoured naftifine 1% compared to placebo across three studies (RR 2.38, 95% CI 1.80 to 3.14, NNT 3, 95% CI 2 to 4) with the quality of evidence rated as low. In one study, naftifine 1% was more effective than placebo in achieving clinical cure (RR 2.42, 95% CI 1.41 to 4.16, NNT 3, 95% CI 2 to 5) with the quality of evidence rated as low.Across two studies, mycological cure rates favoured clotrimazole 1% compared to placebo (RR 2.87, 95% CI 2.28 to 3.62, NNT 2, 95% CI 2 to 3).Data for several outcomes were pooled for three comparisons between different classes of treatment. There was no difference in mycological cure between azoles and benzylamines (RR 1.01, 95% CI 0.94 to 1.07). The quality of the evidence was rated as low for this comparison. Substantial heterogeneity precluded the pooling of data for mycological and clinical cure when comparing azoles and allylamines. Azoles were slightly less effective in achieving clinical cure compared to azole and steroid combination creams immediately at the end of treatment (RR 0.67, 95% CI 0.53 to 0.84, NNT 6, 95% CI 5 to 13), but there was no difference in mycological cure rate (RR 0.99, 95% CI 0.93 to 1.05). The quality of evidence for these two outcomes was rated as low for mycological cure and very low for clinical cure.All of the treatments that were examined appeared to be effective, but most comparisons were evaluated in single studies. There was no evidence for a difference in cure rates between tinea cruris and tinea corporis. Adverse effects were minimal - mainly irritation and burning; results were generally imprecise between active interventions and placebo, and between different classes of treatment. AUTHORS' CONCLUSIONS The pooled data suggest that the individual treatments terbinafine and naftifine are effective. Adverse effects were generally mild and reported infrequently. A substantial number of the studies were more than 20 years old and of unclear or high risk of bias; there is however, some evidence that other topical antifungal treatments also provide similar clinical and mycological cure rates, particularly azoles although most were evaluated in single studies.There is insufficient evidence to determine if Whitfield's ointment, a widely used agent is effective.Although combinations of topical steroids and antifungals are not currently recommended in any clinical guidelines, relevant studies included in this review reported higher clinical cure rates with similar mycological cure rates at the end of treatment, but the quality of evidence for these outcomes was rated very low due to imprecision, indirectness and risk of bias. There was insufficient evidence to confidently assess relapse rates in the individual or combination treatments.Although there was little difference between different classes of treatment in achieving cure, some interventions may be more appealing as they require fewer applications and a shorter duration of treatment. Further, high quality, adequately powered trials focusing on patient-centred outcomes, such as patient satisfaction with treatment should be considered.

Abstract
PURPOSE This randomized, single center, examiner-blind, controlled, parallel-group, 6-month clinical study compared the antiplaque/antigingivitis potential of an essential oil (EO) versus a 0.07% cetylpyridinium chloride (CPC)-containing mouthrinse. A 5% hydroalcohol solution was included as a control group. METHODS 354 healthy volunteers (18-71 years of age) were enrolled in this clinical trial; 338 subjects completed the study. At baseline, 1-, 3-, and 6-month visits, subjects received an oral examination, gingivitis (MGI), gingival bleeding (BI) and plaque assessments (PI). Following randomization, subjects received a prophylaxis and began brushing twice daily with the provided fluoride toothpaste and rinsing twice daily with 20 mL of the assigned mouthrinse for 30 seconds. RESULTS All rinses were well tolerated by the subjects, with the exception of extrinsic tooth stain complaints in 13 subjects in the CPC group between the 3- and 6-month exams. Statistically significant reductions in gingivitis, bleeding and plaque were observed for both EO and CPC at all post-baseline time-points when compared to the negative control. At 6 months MGI and PI were reduced by 42.6% and 42.0% for EO and by 17.1% and 13.9% respectively, for CPC vs. control. When compared to CPC, EO was statistically significantly superior at all post-baseline time-points. EO showed increasing reductions in MGI of 10.5%, 20.3% and 30.7% as well as reductions in PI of 12.7%, 23.7% and 32.6% at 1, 3 and 6 months, respectively. When analyzing the number of healthy sites (MGI scores of 0 or 1), the beneficial effect of the EO-containing mouthrinse is 45.8% greater than using a CPC-containing mouthrinse and 59.8% greater than placebo.

Abstract
PURPOSE The purpose of this study was to verify the influence of prebrushing mouthwashes on dental plaque removal in children. METHODS This study had a double-blind, randomized, controlled, crossover, 25-day experimental design, including 38 12- to 14-year-olds. Four solutions were used as prebrushing mouthwashes (Colgate Plax Magic, Listerine Cool Blue Agent, water and dye, and water) by each participant with seven days' washout. The plaque index was evaluated before and after tooth-brushing during the experimental period. RESULTS Intergroup comparisons showed no significant differences in plaque reduction among evaluated solutions (Friedman test, P>.78). Significantly more plaque was present before vs. after tooth-brushing (Wilcoxon rank test, P<.001), independent of the surface (buccal or lingual/palatal). CONCLUSION Use of prebrushing mouthwashes by children does not influence plaque removal by tooth-brushing.

Abstract
PURPOSE The aim of this investigation through post-hoc analyses was to determine the ability to achieve gingival health in the short term with daily rinsing with an essential oil containing antimicrobial mouthrinse. METHODS Conventional Analysis of Covariance (ANCOVA) on whole mouth mean plaque and gingivitis scores were originally conducted to demonstrate efficacy of adjunctive use of Cool Mint® LISTERINE® Antiseptic (EO) compared to negative control [brushing (B) or brushing/flossing (BF)] in each of 5 studies containing a 4 week evaluation. The Modified Gingival Index (MGI) was split into 2 categories: healthy (scores 0, 1) and unhealthy (≥2). Data, reflecting subjects that completed 4 weeks of treatment from 5 studies, were evaluated to determine the mean percent of healthy sites and mean percent of more inflamed "affected" areas (MGI≥3). RESULTS At baseline, the mean percent healthy gingival sites ranged from 0.1 to 3.2%. At 4 weeks, up to 29.3% and 16.1% of sites were healthy for the EO group and negative control group, respectively. Three and 6 month data from 2 of the 5 studies resulted in up to 39.6% and 62% at 3 and 6 month mean percent healthy sites per subject for EO and up to 17.2% and 15.6% at 3 and 6 months, respectively, for negative control. Virtually plaque free sites (PI=0, 1) at 4 weeks ranged up to 34.3% and 8.1% for EO and control groups, respectively. CONCLUSION Significantly more healthy gingival sites and virtually plaque free tooth surfaces can be achieved as early as 4 weeks with use of an essential oil antimicrobial mouthrinse. This finding continues through 6 months twice daily use as part of oral care practices compared to mechanical oral hygiene alone.
