Review
INTRODUCTION
Raynaud's phenomenon is episodic vasospasm of the peripheral vessels. It presents as episodic colour changes of the digits (sometimes accompanied by pain and paraesthesia), usually in response to cold exposure or stress. The classic triphasic colour change is white (ischaemia), then blue (de-oxygenation), then red (reperfusion). Raynaud's phenomenon can be primary (idiopathic) or secondary to several different conditions and causes. When secondary (e.g., to systemic sclerosis), it can progress to ulceration of the fingers and toes. This review deals with secondary Raynaud's phenomenon.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of surgical interventions in complicated secondary Raynaud's phenomenon? We searched: Medline, Embase, The Cochrane Library, and other important databases up to March 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 two 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: botulinum toxin, simple debridement/surgical toilet of ulcers, peripheral sympathectomy (digital, digital plus sympathectomy of the ulnar and/or radial artery, ligation of the ulnar artery), cervical/thoracic sympathectomy, arterial reconstruction (venous graft, arterial graft, balloon angioplasty), and amputation.

Meta-Analysis Review
Antimicrobial photodynamic therapy (aPDT) has been proposed as an adjunctive treatment strategy for peri-implant diseases. This systematic review aimed to determine whether aPDT as an adjunct to mechanical debridement has an additional benefit for smokers with peri-implant diseases. Randomized controlled trials (RCTs), which evaluated the clinical outcomes of mechanical debridement alone versus mechanical debridement + aPDT among smokers, were considered eligible to be included. The primary outcome was bleeding on probing (BOP) and secondary outcomes included probing depth (PD), plaque index (PI), and crestal bone loss (CBL). Meta-analyses using a random-effects model were conducted to calculate the mean difference (MD) with a 95% confidence interval (CI). The quality of evidence was assessed according to Grading of Recommendations Assessment, Development and Evaluation (GRADE). A total of four RCTs (188 participants) were included. The aPDT group showed significantly improved PD (MD = - 1.26, 95% CI = - 2.19 to - 0.32, p = 0.008) and PI (MD = - 10.6%, 95% CI = - 14.46 to - 6.74%, p = 0.0001) compared with mechanical debridement group at 3-month follow-up. No significant difference in bleeding on probing (BOP) was observed at 3-month follow-up (MD = - 0.60%, 95% CI = - 2.36 to 1.16%, p = 0.50). The subgroup analyses on photosensitizers demonstrated significant differences between the two groups on PD (MD = - 1.23, 95% CI = - 2.41 to - 0.05, p = 0.04) and PI (MD = - 12.33, 95% CI = - 14.74 to - 9.92, p < 0.00001) by the use of methylene blue (MB). Within the limitation of this study, compared with mechanical debridement alone, combined use of aPDT was more effective in reducing PD and PI in smokers at 3-month follow-up. MB was a predictable photosensitizer for aPDT. However, the findings should be interpreted with caution due to the limited number of included studies, methodological deficiencies, and heterogeneity between studies.

Meta-Analysis Review
Superior capsule reconstruction, partial cuff repair, graft interposition, arthroscopic debridement or balloon spacers for large and massive irreparable rotator cuff tears: a systematic review and meta-analysis.
BACKGROUND
Multiple non-arthroplasty surgical techniques are described for the management of large and massive irreparable rotator cuff tears. There is currently no consensus on the best management strategy. Our aim was to compare clinical outcomes following arthroscopic debridement, arthroscopic partial cuff repair, superior capsule reconstruction, balloon spacers or graft interposition for the management of large and massive irreparable rotator cuff tears.
METHODS
A comprehensive search was performed of the following databases: Medline, Embase, CINAHL and Cochrane Database of Systematic Reviews. Data were extracted from relevant studies published since January 2000 according to the pre-specified inclusion criteria. The primary outcome was the post-operative improvement in shoulder scores. Meta-analysis of the primary outcome was performed. Secondary outcomes included retear rates and complications.
RESULTS
Eighty-two studies were included reporting the outcomes of 2790 shoulders. Fifty-one studies were included in the meta-analysis of the primary outcome. The definition of an irreparable tear varied. All procedures resulted in improved shoulder scores at early follow-up. Shoulder scores declined after 2 years following balloon spacers, arthroscopic debridement and partial cuff repair. High retear rates were seen with partial cuff repairs (45%), graft interposition (21%) and superior capsule reconstruction (21%).
CONCLUSIONS
Large initial improvements in shoulder scores were demonstrated for all techniques despite high retear rates for reconstructive procedures. Shoulder scores may decline at mid- to long-term follow-up.

Meta-Analysis
BACKGROUND
Foot wounds in people with diabetes mellitus (DM) are a common and serious global health issue. People with DM are prone to developing foot ulcers and, if these do not heal, they may also undergo foot amputation surgery resulting in postoperative wounds. Negative pressure wound therapy (NPWT) is a technology that is currently used widely in wound care. NPWT involves the application of a wound dressing attached to a vacuum suction machine. A carefully controlled negative pressure (or vacuum) sucks wound and tissue fluid away from the treated area into a canister. A clear and current overview of current evidence is required to facilitate decision-making regarding its use.
OBJECTIVES
To assess the effects of negative pressure wound therapy compared with standard care or other therapies in the treatment of foot wounds in people with DM in any care setting.
SEARCH METHODS
In January 2018, for this first update of this review, we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies, reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting. We identified six additional studies for inclusion in the review.
SELECTION CRITERIA
Published or unpublished randomised controlled trials (RCTs) that evaluated the effects of any brand of NPWT in the treatment of foot wounds in people with DM, irrespective of date or language of publication. Particular effort was made to identify unpublished studies.
DATA COLLECTION AND ANALYSIS
Two review authors independently performed study selection, risk of bias assessment and data extraction. Initial disagreements were resolved by discussion, or by including a third review author when necessary. We presented and analysed data separately for foot ulcers and postoperative wounds.
MAIN RESULTS
Eleven RCTs (972 participants) met the inclusion criteria. Study sample sizes ranged from 15 to 341 participants. One study had three arms, which were all included in the review. The remaining 10 studies had two arms. Two studies focused on postamputation wounds and all other studies included foot ulcers in people with DM. Ten studies compared NPWT with dressings; and one study compared NPWT delivered at 75 mmHg with NPWT delivered at 125 mmHg. Our primary outcome measures were the number of wounds healed and time to wound healing.NPWT compared with dressings for postoperative woundsTwo studies (292 participants) compared NPWT with moist wound dressings in postoperative wounds (postamputation wounds). Only one study specified a follow-up time, which was 16 weeks. This study (162 participants) reported an increased number of healed wounds in the NPWT group compared with the dressings group (risk ratio (RR) 1.44, 95% confidence interval (CI) 1.03 to 2.01; low-certainty evidence, downgraded for risk of bias and imprecision). This study also reported that median time to healing was 21 days shorter with NPWT compared with moist dressings (hazard ratio (HR) calculated by review authors 1.91, 95% CI 1.21 to 2.99; low-certainty evidence, downgraded for risk of bias and imprecision). Data from the two studies suggest that it is uncertain whether there is a difference between groups in amputation risk (RR 0.38, 95% CI 0.14 to 1.02; 292 participants; very low-certainty evidence, downgraded once for risk of bias and twice for imprecision).NPWT compared with dressings for foot ulcersThere were eight studies (640 participants) in this analysis and follow-up times varied between studies. Six studies (513 participants) reported the proportion of wounds healed and data could be pooled for five studies. Pooled data (486 participants) suggest that NPWT may increase the number of healed wounds compared with dressings (RR 1.40, 95% CI 1.14 to 1.72; I² = 0%; low-certainty evidence, downgraded once for risk of bias and once for imprecision). Three studies assessed time to healing, but only one study reported usable data. This study reported that NPWT reduced the time to healing compared with dressings (hazard ratio (HR) calculated by review authors 1.82, 95% CI 1.27 to 2.60; 341 participants; low-certainty evidence, downgraded once for risk of bias and once for imprecision).Data from three studies (441 participants) suggest that people allocated to NPWT may be at reduced risk of amputation compared with people allocated to dressings (RR 0.33, 95% CI 0.15 to 0.70; I² = 0%; low-certainty evidence; downgraded once for risk of bias and once for imprecision).Low-pressure compared with high-pressure NPWT for foot ulcersOne study (40 participants) compared NPWT 75 mmHg and NPWT 125 mmHg. Follow-up time was four weeks. There were no data on primary outcomes. There was no clear difference in the number of wounds closed or covered with surgery between groups (RR 0.83, 95% CI 0.47 to 1.47; very low-certainty evidence, downgraded once for risk of bias and twice for serious imprecision) and adverse events (RR 1.50, 95% CI 0.28 to 8.04; very low-certainty evidence, downgraded once for risk of bias and twice for serious imprecision).
AUTHORS' CONCLUSIONS
There is low-certainty evidence to suggest that NPWT, when compared with wound dressings, may increase the proportion of wounds healed and reduce the time to healing for postoperative foot wounds and ulcers of the foot in people with DM. For the comparisons of different pressures of NPWT for treating foot ulcers in people with DM, it is uncertain whether there is a difference in the number of wounds closed or covered with surgery, and adverse events. None of the included studies provided evidence on time to closure or coverage surgery, health-related quality of life or cost-effectiveness. The limitations in current RCT evidence suggest that further trials are required to reduce uncertainty around decision-making regarding the use of NPWT to treat foot wounds in people with DM.

Meta-Analysis Review
BACKGROUND
Suboccipital decompressive craniectomy (SDC) for cerebellar infarction has been traditionally performed with minimal high-quality evidence. The aim of this systematic review and meta-analysis is to investigate the impact of SDC on functional outcomes, mortality, and adverse events in patients with cerebellar infarcts.
METHODS
A systematic review and meta-analysis in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Our primary outcome was the proportion of patients with moderate-severe disability after SDC. Secondary outcomes included mortality and adverse events. A sensitivity analysis was conducted to examine the roles of age, preoperative neurologic status, external ventricular drain insertion, and debridement of infarcted tissue on SDC outcomes.
RESULTS
Eleven studies (with 283 patients) met our inclusion criteria. The pooled event rate for moderate-severe disability was 28% (95% confidence interval [CI], 20%-37%) and for mortality, it was 20% (95% CI, 12%-31%). The estimated overall rate of adverse events for SDC was 23% (95% CI, 14%-35%). Sensitivity analysis found less mortality with mean age <60 years, higher rates of concomitant external ventricular drain insertion, and debridement of infarcted tissue. Several factors were identified for heterogeneity between studies, including follow-up time, outcomes scale, extent of infarction, and other neuroimaging features.
CONCLUSIONS
The best available evidence for SDC is based on retrospective observational studies. SDC for cerebellar infarction is associated with better outcomes compared with decompressive surgery for hemispheric infarctions. Lack of standardized reporting methods for SDC is a considerable drawback to the development of a better understanding of the impact of this surgery on patient outcomes.

Review
INTRODUCTION
Fungal infections are reported to cause 23% of foot diseases and 50% of nail conditions in people seen by dermatologists, but are less common in the general population, affecting 3-5% of people.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of oral treatments for fungal toenail infections? What are the effects of topical treatments for fungal toenail infections? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2008 (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 11 systematic reviews, RCTs, or observational 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: amorolfine, butenafine, ciclopirox, fluconazole, griseofulvin, itraconazole, ketoconazole, mechanical debridement, terbinafine, and tioconazole.

Optimal wound care is an essential component in the management of systemic sclerosis (SSc) digital ulcers (DUs). DU debridement has been suggested to reduce ulcer-related pain and improve tissue healing. However, only a minority of rheumatologists perform DU debridement, and there is no standard of care/protocol. Our objectives were to (i) evaluate the current evidence for the use of debridement in DU management and (ii) assess whether there are any specific protocols. A systematic literature review was performed searching the PubMed database (between 01/01/1950-01/03/2019) in accordance with PRISMA guidelines. Two independent reviewers screened and extracted the abstracts/full manuscripts. Articles in English, which focussed on SSc-DU debridement/curettage, were included. Exclusion criteria included studies of juvenile/paediatric patients and basic/non-clinical research. Our search identified 1497 studies of which 4 studies were included in our final analysis. Three studies used scalpel debridement, and one study used this in combination with autolytic debridement. No studies specifically reported the effect on DU healing from debridement. Autolytic debridement with hyaluronate-based products was associated with significant ulcer pain and inflammation. Local anaesthetic significantly reduces pain both during and after debridement. Combined local and oral analgesia is often required for more severe or infected DUs. DU (scalpel and autolytic) debridement is being used by some clinicians in rheumatology; however, there are no standardised protocols. To improve wound care for SSc-DUs, future research should focus on developing a standardised protocol for SSc-DU debridement, with a view to facilitate randomised controlled trials to demonstrate safety and treatment efficacy.Key Points• Optimal wound care is an essential component in the management of systemic sclerosis-digital ulcers.• 'Sharp' debridement uses a scalpel, whereas 'autolytic' debridement uses dressings to optimize endogenous tissue lysis.• There is significant variation in the use of digital ulcer debridement in systemic sclerosis.• A standardized protocol and randomized controlled trials are needed to demonstrate debridement the safety and efficacy of digital ulcer debridement in systemic sclerosis.

Review
A systematic review and meta-analysis were carried out to investigate the effect of ultrasound-assisted wound (UAW) debridement in patients with diabetic foot ulcers (DFUs). All selected studies were evaluated using the Cochrane risk of bias tool to assess the risk of bias for randomized controlled trials. PubMed and Web of Science were searched in October 2021 to find randomized clinical trials (RCT) assessing the effect of UAW debridement on DFUs. RevMan v5.4. was used to analyze the data with the Mantel-Haenszel method for dichotomous outcomes. A total of 8 RCT met our inclusion criteria, with 263 participants. Concerning the healing rate comparing UAW versus the control group, a meta-analysis estimated the pooled OR at 2.22 (95% CI 0.96-5.11, = 0.06), favoring UAW debridement, with low heterogeneity (x = 7.47, df = 5, = 0.19, I = 33%). Time to healing was similar in both groups: UAW group (14.25 ± 10.10 weeks) versus the control group (13.38 ± 1.99 weeks, = 0.87). Wound area reduction was greater in the UAW debridement group (74.58% ± 19.21%) than in the control group (56.86% ± 25.09%), although no significant differences were observed between them ( 0.24). UAW debridement showed higher healing rates, a greater percentage of wound area reduction, and similar healing times when compared with placebo (sham device) and standard of care in patients with DFUs, although no statistically significant differences were observed between groups.

Review
INTRODUCTION
Leg ulcers usually occur secondary to venous reflux or obstruction, but 20% of people with leg ulcers have arterial disease, with or without venous disorders. Between 1.5 and 3.0/1000 people have active leg ulcers. Prevalence increases with age to about 20/1000 in people aged over 80 years.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of standard treatments, adjuvant treatments, and organisational interventions for venous leg ulcers? What are the effects of advice about self-help interventions in people receiving usual care for venous leg ulcers? What are the effects of interventions to prevent recurrence of venous leg ulcers? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2011 (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 101 systematic reviews, RCTs, or observational 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: compression bandages and stockings, cultured allogenic (single or bilayer) skin replacement, debriding agents, dressings (cellulose, collagen, film, foam, hyaluronic acid-derived, semi-occlusive alginate), hydrocolloid (occlusive) dressings in the presence of compression, intermittent pneumatic compression, intravenous prostaglandin E1, larval therapy, laser treatment (low-level), leg ulcer clinics, multilayer elastic system, multilayer elastomeric (or non-elastomeric) high-compression regimens or bandages, oral treatments (aspirin, flavonoids, pentoxifylline, rutosides, stanozolol, sulodexide, thromboxane alpha(2) antagonists, zinc), peri-ulcer injection of granulocyte-macrophage colony-stimulating factor, self-help (advice to elevate leg, to keep leg active, to modify diet, to stop smoking, to reduce weight), short-stretch bandages, single-layer non-elastic system, skin grafting, superficial vein surgery, systemic mesoglycan, therapeutic ultrasound, and topical treatments (antimicrobial agents, autologous platelet lysate, calcitonin gene-related peptide plus vasoactive intestinal polypeptide, freeze-dried keratinocyte lysate, mesoglycan, negative pressure, recombinant keratinocyte growth factor, platelet-derived growth factor).

Meta-Analysis
OBJECTIVES
We aimed to assess infection control rates after DAIR in patients with periprosthetic joint infection (PJI) following joint arthroplasty and evaluate factors associated with infection control using a systematic review and meta-analysis.
METHODS
We searched MEDLINE, EMBASE, Web of Science, Cochrane databases and reference lists of relevant studies up to May 2017. Longitudinal studies conducted in patients with PJI treated exclusively by DAIR were eligible. Infection control rates were meta-analysed using random-effect models after arcsine transformation.
RESULTS
We included 93 articles based on 99 unique observational studies with data on 4897 PJIs treated by DAIR. The infection control rate for DAIR ranged from 11.1% to 100% with an overall pooled estimate of 61.4% (95% CI, 57.3-65.4) and a 95% prediction interval of 25.5% to 91.8%. Infection control rates remained generally similar for several relevant characteristics, except for evidence of variation by age, geographical location, type of infection and joint affected, duration of parenteral antibiotic therapy after the DAIR procedure, and period (year) of DAIR procedure.
CONCLUSIONS
The DAIR approach remains an option for the treatment of PJI as it is associated with acceptable infection control rates, particularly in acute postoperative infections and infections of the hip and shoulder joints.
