Meta-Analysis
BACKGROUND
Randomized clinical trials (RCTs) investigating the impact of omega-3-fatty acid supplementation on cardiovascular events have largely shown no benefit. However, there is debate about the benign nature of the placebo in these trials. We aimed to conduct a network meta-analysis of RCTs to compare the outcomes of omega-3 fatty acid supplementation to various placebo oils.
METHODS
MEDLINE and EMBASE were searched through May, 2021 to identify RCTs investigating cardiovascular outcomes with omega-3-fatty acid formulations [eicosapentaenoic acid (EPA), decosahexanoic acid (DHA), or the combination] versus placebo or standard of care controls.
RESULTS
Our analysis included 17 RCTs that enrolled a total of 141,009 patients randomized to EPA (n=13,655), EPA+DHA (n=56,908), mineral oil placebo (n=5,338), corn oil placebo (n =8,876), olive oil placebo (n=41,009), and controls (no placebo oil; n=15,223). Rates of cardiovascular death [hazard ratio (HR) (95% confidence interval, CI) =0.80 (0.65-0.98); p =0.033], myocardial infarction [HR (95% CI) =0.73 (0.55-0.97); p=0.029] and stroke [HR (95% CI) =0.74 (0.58-0.94); p=0.014] were significantly lower in those receiving EPA compared to those receiving mineral oil, but were not different from rates in those receiving other oils or controls. Rates of coronary revascularization were significantly lower in those receiving EPA than in those receiving either EPA+DHA, mineral oil, corn oil, or olive oil placebo, but not controls. All-cause death was similar among all groups, but combined EPA+DHA was associated with reduced risk of cardiovascular death compared to controls [HR (95%CI): 0.83 (0.71-0.98)].
CONCLUSIONS
Our analyses demonstrate that although EPA supplementation lowers risk of coronary revascularization more than other oils, there may not be a benefit relative to standard of care. Further, EPA reduces the risk of cardiovascular events only in comparison to mineral oil and not when compared with other placebo oils or controls. In contrast, combined EPA+DHA was associated with reduced risk of cardiovascular death compared to controls.

Review
Diaper dermatitis (DD) is one of the most common skin conditions in neonates and infants, with a peak between the ages of 9 and 12 months. Appropriate skin care practices that support skin barrier function and protect the buttocks skin from urine and feces are supposed to be effective in the prevention of DD. Despite many recommendations for parents and caregivers on proper diaper skin care, there is no up-to-date synthesis of the available evidence to develop recommendations for DD prevention practice. Therefore we performed a systematic literature review on the efficacy of nonmedical skin care practices on the diapered area of healthy, full-term infants ages 0 to 24 months. We identified 13 studies covering skin care practices such as cleansing, bathing, and application of topical products. DD prevalence and incidence and physiologic skin parameters were used as efficacy parameters. The results of this review indicate that cleansing of the diaper area using baby wipes or water and a washcloth have comparable effects on diapered skin. Bathing with a liquid baby cleanser twice weekly seems comparable with water alone. The application of ointments containing zinc oxide or petrolatum with or without vitamin A seems to have comparable effects on DD severity. There seems to be no information on whether single skin care practices such as cleansing, bathing, and application of topical preparations can prevent DD. High-quality randomized clinical trials are needed to show the effectiveness of skin care practices for controlling and preventing DD.

Meta-Analysis Review
BACKGROUND
Following surgery, incisions are usually closed by fixing the edges together with sutures (stitches), staples, adhesives (glue) or clips. This process helps the cut edges heal together and is called 'healing by primary intention'. However, a minority of surgical wounds are not closed in this way. Where the risk of infection is high or there has been significant loss of tissue, wounds may be left open to heal by the growth of new tissue rather than by primary closure; this is known as 'healing by secondary intention'. There is a risk of infection in open wounds, which may impact on wound healing, and antiseptic or antibiotic treatments may be used with the aim of preventing or treating such infections. This review is one of a suite of Cochrane reviews investigating the evidence on antiseptics and antibiotics in different types of wounds. It aims to present current evidence related to the use of antiseptics and antibiotics for surgical wounds healing by secondary intention (SWHSI).
OBJECTIVES
To assess the effects of systemic and topical antibiotics, and topical antiseptics for the treatment of surgical wounds healing by secondary intention.
SEARCH METHODS
In November 2015 we searched: The Cochrane Wounds Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE and EBSCO CINAHL. We also searched three clinical trials registries and the references of included studies and relevant systematic reviews. There were no restrictions with respect to language, date of publication or study setting.
SELECTION CRITERIA
Randomised controlled trials which enrolled adults with a surgical wound healing by secondary intention and assessed treatment with an antiseptic or antibiotic treatment. Studies enrolling people with skin graft donor sites were not included, neither were studies of wounds with a non-surgical origin which had subsequently undergone sharp or surgical debridement or other surgical treatments or wounds within the oral or aural cavities.
DATA COLLECTION AND ANALYSIS
Two review authors independently performed study selection, risk of bias assessment and data extraction.
MAIN RESULTS
Eleven studies with a total of 886 participants were included in the review. These evaluated a range of comparisons in a range of surgical wounds healing by secondary intention. In general studies were small and some did not present data or analyses that could be easily interpreted or related to clinical outcomes. These factors reduced the quality of the evidence.Two comparisons compared different iodine preparations with no antiseptic treatment and found no clear evidence of effects for these treatments. The outcome data available were limited and what evidence there was low quality.One study compared a zinc oxide mesh dressing with a plain mesh dressing. There was no clear evidence of a difference in time to wound healing between groups. There was some evidence of a difference in measures used to assess wound infection (wound with foul smell and number of participants prescribed antibiotics) which favoured the zinc oxide group. This was low quality evidence.One study reported that sucralfate cream increased the likelihood of healing open wounds following haemorrhoidectomy compared to a petrolatum cream (RR: 1.50, 95% CI 1.13 to 1.99) over a three week period. This evidence was graded as being of moderate quality. The study also reported lower wound pain scores in the sucralfate group.There was a reduction in time to healing of open wounds following haemorrhoidectomy when treated with Triclosan post-operatively compared with a standard sodium hypochlorite solution (mean difference -1.70 days, 95% CI -3.41 to 0.01). This was classed as low quality evidence.There was moderate quality evidence that more open wounds resulting from excision of pyomyositis abscesses healed when treated with a honey-soaked gauze compared with a EUSOL-soaked gauze over three weeks' follow-up (RR: 1.58, 95% CI 1.03 to 2.42). There was also some evidence of a reduction in the mean length of hospital stay in the honey group. Evidence was taken from one small study that only had 43 participants.There was moderate quality evidence that more Dermacym®-treated post-operative foot wounds in people with diabetes healed compared to those treated with iodine (RR 0.61, 95% CI 0.40 to 0.93). Again estimates came from one small study with 40 participants.
AUTHORS' CONCLUSIONS
There is no robust evidence on the relative effectiveness of any antiseptic/antibiotic/anti-bacterial preparation evaluated to date for use on SWHSI. Where some evidence for possible treatment effects was reported, it stemmed from single studies with small participant numbers and was classed as moderate or low quality evidence. This means it is likely or very likely that further research will have an important impact on our confidence in the estimate of effect, and may change this estimate.

Meta-Analysis
BACKGROUND
Topical occlusive agents, such as petroleum jelly and silicone oils, kill head lice by coating and blocking its excretory system and are unlikely to induce treatment resistance. Although a popular alternative to neurotoxic pediculicides, their efficacy and safety remain unclear.
METHODS
We searched CENTRAL, MEDLINE, HERDIN (from inception to October 31, 2017), and other relevant sources for randomized controlled trials that compared topical occlusive agents with neurotoxic pediculicides to treat patients with head lice infestation. Using Cochrane collaboration methods, we selected studies, assessed risk of bias, and pooled similar studies. We assessed certainty of evidence using GRADEPro.
RESULTS
Seventeen trials (N = 2005) testing occlusive agents met inclusion criteria. Risk of bias was moderate across trials, mainly from lack of blinding of participants and personnel. As a class, occlusive agents may be more pediculicidal than neurotoxic agents (final cure rate, RR 1.20, 95% CI 1.02, 1.41; 16 RCTs, N = 1779; I = 88%; low certainty of evidence). Post hoc subgroup analysis suggests that this benefit may be limited to synthetic combination occlusive products. Adverse effects, such as skin and eye irritation, are similar between groups (RR 0.65, 95% CI 0.36, 1.17; 15 RCTs, N = 1790; I = 28%; low certainty of evidence).
CONCLUSIONS
In treating head louse infestation, evidence suggests occlusive agents may be superior to or equally efficacious as neurotoxic pediculicides. Adverse effects are few and minor. Future trials should use appropriate comparators and consider effects of confounders such as neurotoxin resistance. Additionally, optimal occlusive formulation and dosing regimen need to be determined.

Review
BACKGROUND
Recurrent idiopathic epistaxis (nosebleeds) in children is repeated nasal bleeding in patients up to the age of 16 for which no specific cause has been identified. Although nosebleeds are very common in children, and most cases are self-limiting or settle with simple measures (such as pinching the nose), more severe recurrent cases can require treatment from a healthcare professional. However, there is no consensus on the effectiveness of the different clinical interventions currently used in managing this condition.
OBJECTIVES
To assess the effects of different interventions for the management of recurrent idiopathic epistaxis in children.
SEARCH STRATEGY
We searched the Cochrane ENT Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library Issue 3, 2003), MEDLINE (January 1966 to August 2003), EMBASE (January 1980 to August 2003), CINAHL (January 1982 to August 2003), and reference lists of relevant articles.
SELECTION CRITERIA
We identified all randomised controlled trials (with or without blinding) in which any surgical or medical intervention for the treatment of recurrent idiopathic epistaxis in children was evaluated in comparison with either no treatment, a placebo, or another intervention, and in which the frequency and severity of episodes of nasal bleeding following treatment was stated or calculable. The full text articles of all the retrieved trials of possible relevance were reviewed by the two reviewers and the inclusion criteria applied independently.
DATA COLLECTION AND ANALYSIS
Trials were graded for methodological quality using the Cochrane approach. Data extraction was performed in a standardised manner by one reviewer and rechecked by the other, and where necessary investigators were contacted to obtain missing information. A meta-analysis was not undertaken because of the heterogeneity of the treatments, procedures and quality of the included trials. A narrative overview of the results is therefore presented.
MAIN RESULTS
Three studies - two randomised controlled trials (RCTs) and one controlled clinical trial (CCT) - involving 256 participants satisfied the inclusion criteria. One RCT compared Naseptin antiseptic cream with no treatment, the second RCT compared Vaseline(R) petroleum jelly with no treatment, and the CCT compared Naseptin antiseptic cream with silver nitrate cautery. Overall, results were inconclusive, with no statistically significant difference found between the compared treatments. No serious adverse effects were reported from any of the interventions, although children receiving silver nitrate cautery reported that it was a painful experience (despite the use of local anaesthetic).
REVIEWER'S CONCLUSIONS
The optimal management of children with recurrent idiopathic epistaxis is unknown. High quality randomised controlled trials comparing interventions either with placebo or no treatment, and with a follow-up period of at least a year, are needed to assess the relative merits of the various treatments currently in use.

Meta-Analysis Review
BACKGROUND
Constipation within childhood is an extremely common problem. Despite the widespread use of osmotic and stimulant laxatives by health professionals to manage constipation in children, there has been a long standing paucity of high quality evidence to support this practice.
OBJECTIVES
We set out to evaluate the efficacy and safety of osmotic and stimulant laxatives used to treat functional childhood constipation.
SEARCH METHODS
The search (inception to May 7, 2012) was standardised and not limited by language and included electronic searching (MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Inflammatory Bowel Disease and Functional Bowel Disorders Group Specialized Trials Register), reference searching of all included studies, personal contacts and drug companies.
SELECTION CRITERIA
Randomised controlled trials (RCTs) which compared osmotic or stimulant laxatives with either placebo or another intervention, with patients aged 0 to 18 years old were considered for inclusion. The primary outcome was frequency of defecation. Secondary endpoints included faecal incontinence, disimpaction, need for additional therapies and adverse events.
DATA COLLECTION AND ANALYSIS
Relevant papers were identified and the authors independently assessed the eligibility of trials. Methodological quality was assessed using the Cochrane risk of bias tool.The Cochrane RevMan software was used for analyses. Patients with final missing outcomes were assumed to have relapsed. For continuous outcomes we calculated a mean difference (MD) and 95% confidence interval (CI) using a fixed-effect model. For dichotomous outcomes we calculated an odds ratio (OR) and 95% confidence intervals (95% CI) using a fixed-effect model. The chi square and I(2) statistics were used to assess statistical heterogeneity. A random-effects model was used in situations of unexplained heterogeneity
MAIN RESULTS
Eighteen RCTs (1643 patients) were included in the review. Nine studies were judged to be at high risk of bias due to lack of blinding, incomplete outcome data and selective reporting. Meta-analysis of two studies (101 patients) comparing polyethylene glycol (PEG) with placebo showed a significantly increased number of stools per week with PEG (MD 2.61 stools per week, 95% CI 1.15 to 4.08). Common adverse events in the placebo-controlled studies included flatulence, abdominal pain, nausea, diarrhoea and headache. Meta-analysis of 4 studies with 338 participants comparing PEG with lactulose showed significantly greater stools per week with PEG (MD 0.95 stools per week, 95% CI 0.46 to 1.44), although follow up was short. Patients who received PEG were significantly less likely to require additional laxative therapies. Eighteen per cent of PEG patients required additional therapies compared to 30% of lactulose patients (OR 0.49, 95% CI 0.27 to 0.89). No serious adverse events were reported with either agent. Common adverse events in these studies included diarrhoea, abdominal pain, nausea, vomiting and pruritis ani. Meta-analysis of 3 studies with 211 participants comparing PEG with milk of magnesia showed that the stools/wk was significantly greater with PEG (MD 0.69 stools per week, 95% CI 0.48 to 0.89). However, the magnitude of this difference is quite small and may not be clinically significant. One child was noted to be allergic to PEG, but there were no other serious adverse events reported. Meta-analysis of 2 studies with 287 patients comparing liquid paraffin (mineral oil) with lactulose revealed a relatively large statistically significant difference in the number of stools per week favouring paraffin (MD 4.94 stools per week, 95% CI 4.28 to 5.61). No serious adverse events were reported. Adverse events included abdominal pain, distention and watery stools. No statistically significant differences in the number of stools per week were found between PEG and enemas (1 study, 90 patients, MD 1.00, 95% CI -1.58 to 3.58), dietary fibre mix and lactulose (1 study, 125 patients, P = 0.481), senna and lactulose (1 study, 21 patients, P > 0.05), lactitol and lactulose (1 study, 51 patients, MD -0.80, 95% CI -2.63 to 1.03), and PEG and liquid paraffin (1 study, 158 patients, MD 0.70, 95% CI -0.38 to 1.78).
AUTHORS' CONCLUSIONS
The pooled analyses suggest that PEG preparations may be superior to placebo, lactulose and milk of magnesia for childhood constipation. GRADE analyses indicated that the overall quality of the evidence for the primary outcome (number of stools per week) was low or very low due to sparse data, inconsistency (heterogeneity), and high risk of bias in the studies in the pooled analyses. Thus, the results of the pooled analyses should be interpreted with caution because of quality and methodological concerns, as well as clinical heterogeneity, and short follow up. However, PEG appears safe and well tolerated. There is also evidence suggesting the efficacy of liquid paraffin (mineral oil), which was also well tolerated.There is no evidence to demonstrate the superiority of lactulose when compared to the other agents studied, although there is a lack of placebo controlled studies. Further research is needed to investigate the long term use of PEG for childhood constipation, as well as the role of liquid paraffin.

BACKGROUND
To improve the penile contour, some men choose to undergo implantation or injection of nonbiological materials. Foreign body reactions in penile tissue may produce scarring, deformity, ulceration, necrosis, and even gangrene. Consensus is lacking regarding the most effective surgical procedure for reconstruction of these penile lesions.
OBJECTIVES
The authors describe one case study and the first systematic review focusing on reconstructive surgical management for penile lesions secondary to foreign body reaction.
METHODS
PubMed, Medline, and Cochrane databases were queried for publications written in English, French, Portuguese, and Spanish from 1951 to May 2017. Multiple search terms were applied.
RESULTS
Of the 3304 articles identified, 51 were included in the systematic review. All were retrospective studies, case series, or case reports. A total of 260 patients underwent surgical procedures, and the complication rate was 37.3%. The scrotal flap technique was performed most frequently (43.4%) and resulted in 65.6% of the total complications observed. One Brazilian case study was also described with an extensive and circumferential ulcer after six mineral oil bolls implant in the penile subcutaneous tissue.
CONCLUSIONS
Restoration of the penile shape preserving the functionality and maintaining a good physician-patient relationship may be a challenge. The scrotal pouch may be advantageous for patch grafting of penile soft-tissue lesions, owing to its skin laxity and good blood supply. A less aggressive surgical approach has the benefits of shorter healing time and fewer early complications. Penile injuries are best treated by experienced surgeons on a case-by-case basis with care given to identify the most appropriate treatment.

Review
BACKGROUND
Recurrent idiopathic epistaxis (nosebleeds) in children is repeated nasal bleeding in patients up to the age of 16 for which no specific cause has been identified. Although nosebleeds are very common in children, and most cases are self limiting or settle with simple measures (such as pinching the nose), more severe recurrent cases can require treatment from a healthcare professional. However, there is no consensus on the effectiveness of the different clinical interventions currently used in managing this condition.
OBJECTIVES
To assess the effects of different interventions for the management of recurrent idiopathic epistaxis in children.
SEARCH METHODS
We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the most recent search was 5 March 2012.
SELECTION CRITERIA
We identified all randomised controlled trials (RCTs) (with or without blinding) in which any surgical or medical intervention for the treatment of recurrent idiopathic epistaxis in children was evaluated in comparison with either no treatment, a placebo or another intervention, and in which the frequency and severity of episodes of nasal bleeding following treatment was stated or calculable. The two authors reviewed the full-text articles of all retrieved trials of possible relevance and applied the inclusion criteria independently.
DATA COLLECTION AND ANALYSIS
We graded trials for risk of bias using the Cochrane approach. One author performed data extraction in a standardised manner and this was rechecked by the other author. Where necessary we contacted investigators to obtain missing information. We did not undertake a meta-analysis because of the heterogeneity of the treatments, procedures and quality of the included trials. A narrative overview of the results is therefore presented.
MAIN RESULTS
Five studies (four RCTs and one quasi-randomised controlled trial) involving 468 participants satisfied the inclusion criteria. The identified RCTs compared 0.5% neomycin + 0.1% chlorhexidine (Naseptin®) cream with no treatment, Vaseline® petroleum jelly with no treatment, 75% with 95% silver nitrate nasal cautery, and silver nitrate cautery combined with Naseptin® against Naseptin® alone; the quasi-randomised controlled trial compared Naseptin® antiseptic cream with silver nitrate cautery. Overall results were inconclusive, with no statistically significant difference found between the compared treatments upon completion of the trials, however 75% silver nitrate was more effective than 95% silver nitrate at two weeks following application. The group treated with 75% silver nitrate had 88% complete resolution of epistaxis compared to 65% in the group treated with 95% silver nitrate (P = 0.01). No serious adverse effects were reported from any of the interventions, although children receiving silver nitrate cautery reported that it was a painful experience (despite the use of local anaesthetic). The pain scores were significantly less in those treated with 75% silver nitrate, the mean score being 1 compared to a mean score of 5 in those treated with 95% silver nitrate; this was statistically significant (P = 0.001).We carried out a 'Risk of bias' assessment of each study according to the Cochrane methodology and judged that two randomised controlled trials had a low risk of bias, two had an unclear risk of bias and the quasi-randomised controlled trial had a high risk of bias.
AUTHORS' CONCLUSIONS
The optimal management of children with recurrent idiopathic epistaxis is unknown, however if silver nitrate nasal cautery is undertaken 75% is preferable to 95% as it is more effective in the short term and causes less pain. High-quality randomised controlled trials comparing interventions either with placebo or no treatment, and with a follow-up period of at least a year, are needed to assess the relative merits of the various treatments currently in use.
