Introduction. Controversy exists regarding the use of NPWT for wound healing. Objective. This study assessed the effectiveness of NPWT compared with conventional treatment in the management of different wound types, including acute and chronic wounds. Materials and Methods. PubMed, Cochrane Central Register of Controlled Trials, Scopus, EMBASE, EBSCO, Ovid, and Web of Science were searched, from database inception up to October 2021, for relevant studies comparing NPWT with conventional treatment for wound healing. Primary outcomes included time to healing, wound healing rate, and duration of treatment. Secondary outcomes included adverse events, length of hospital stay, and 30-day mortality rate. Pooled analysis of the outcomes data is presented as SMD (95% CI) for continuous data and OR (95% CI) for dichotomous data. Results. Twenty-four studies (3064 patients) were included in the meta-analysis. NPWT was associated with shorter time to healing (SMD, −0.79; 95% CI, −1.22 to −0.37), shorter duration of treatment (SMD, −1.24; 95% CI, −1.92 to −0.56), and higher rate of wound healing (OR, 2.05; 95% CI, 1.49-2.83) compared with control. NPWT was also associated with a lower incidence of adverse events (OR, 0.42; 95% CI, 0.23-0.77) and a lower 30-day mortality rate (OR, 0.25; 95% CI, 0.12-0.56). There were no significant differences between NPWT and control regarding hospital stay (SMD, −0.52; 95% CI, −1.06 to 0.03). Conclusions. NPWT is seemingly associated with better wound healing outcomes compared with conventional therapy. However, the data should be interpreted with substantial caution given limitations such as high heterogeneity between studies and the small sample size of the included studies.

Purpose The aim of this systematic review is to update and synthesize new evidence on BREAST-Q questionnaire’s ability to reflect patient-reported outcomes in women who have undergone breast reconstruction surgery (BRS) following mastectomy. Methods PubMed, Science Direct, Google Scholar, Cochrane CENTRAL, and Clincaltrial.gov were searched for relevant studies from January 2009 to September 2021. Any interventional or observational studies that used BREAST-Q to assess patient-reported outcomes in the assessment of BRS following mastectomy were included. Results A total of 42 studies were eligible for inclusion in the review. Three were randomized controlled trials and 39 were observational studies. Compared with pre-operative scores, there was an improvement in all BREAST-Q outcome domains following BRS including ‘satisfaction with breasts’, “satisfaction with outcome” “psychosocial”, “physical”, and “sexual wellbeing”. Sexual well-being had the lowest BREAST-Q score both pre-and post-operatively (37.8–80.0 and 39.0–78.0, respectively). Autologous BRS reports higher satisfaction and overall wellbeing compared to implant-based BRS. BREAST-Q has a higher and narrow internal consistency of 0.81 to 0.96 compared with other patient-reported outcome measures (PROMs; EORTC-QLQ, FACT-B, BR-23, BCTOS). The BREAST-Q questionnaire is the only PROM which allows patients to reflect on their care, surgical outcomes, and satisfaction collectively. Conclusion This review highlights the fact that BREAST-Q can effectively and reliably measure satisfaction and wellbeing of breast cancer patients after BRS. Comparatively, sexual wellbeing shows poorer outcomes following BRS and more longitudinal studies are necessary to understand the basis for these findings. Compared to other PROMs, BREAST-Q is reliable and specific to breast cancer surgery. Overall, BREAST-Q can help clinicians improve their quality of service, understand patient experiences, and may be used as an auditing tool for surgical outcomes.

Complex regional pain syndrome type 1 (CRPS-I) is a devastating complication that can occur after limb extremity injuries. The effectiveness of vitamin C in preventing CRPS-I incidence is debatable. Therefore, we conducted a systematic review and meta-analysis to assess the role of vitamin C in CRPS-I prevention and its effect on pain score, functional outcomes and complications rate after wrist, ankle, and foot fractures.We searched Medline, Embase, the Cochrane Library, Clinicaltrial.gov, and Google Scholar from infinity to May 2021 for relevant studies comparing the incidence of CRPS-I with administration of perioperative vitamin C versus placebo after wrist, ankle, and foot fractures. Continuous data such as functional outcomes and pain scores were pooled as mean differences (MD), whist dichotomous variables such as the incidence of CRPS-I and complications were pooled as odds ratios (OR), with 95% confidence interval (CI). Data analyses was done using R software (meta package, version 4.9-0) for Windows.Eight studies, including two quasi-experimental studies, were included. The timeframe for vitamin C administration ranged from 42 to 50 days post-injury and/or surgical fixation and the dosage was either 500 mg or 1000 mg. The results showed that vitamin C was associated with a lower rate of CRPS-I relative to a placebo (OR 0.33, 95% CI [0.17, 0.63]). No significant difference was found between vitamin C and placebo in terms of complications (OR 1.90, 95% CI [0.99, 3.65]), functional outcomes (MD 6.37, 95% CI [-1.40, 14.15]), and pain scores (MD −0.14, 95% CI [-1.07, 0.79]).The findings demonstrate that when compared to placebo, at least 42 days of vitamin C prophylaxis is associated with prevention of CRPS-I following wrist, ankle, and foot fractures, irrespective of vitamin C dosage or fracture type. No significant differences were found with secondary outcomes.

Purpose High tibial osteotomy (HTO) and unicompartmental knee arthroplasty (UKA) are commonly performed procedures for the treatment of compartmental knee osteoarthritis. However, the optimal procedure remains controversial. Therefore, we conducted this systematic review and meta-analysis to compare the functional outcomes, complications, and revision between the two techniques.Methods We searched electronic databases for relevant studies comparing HTO versus UKA for unicompartmental knee osteoarthritis. Continuous data as visual analogue scale (VAS), range of motion, and free walking speed were pooled as mean differences (MDs). Dichotomous data as functional knee outcomes, complications, and revision were pooled as odds ratios (ORs), with 95% confidence interval (CI), using R software for windows.Results Twenty-five studies involving 8185 patients were included. Meta-analysis showed that HTO was associated with higher risk of complications (OR= 2.47, 95% CI [1.52, 4.04]), poor functional results (excellent/good) (OR= 0.32, 95% CI [0.21, 0.49]), and larger range of motion (MD= 7.05, 95% CI [2.41, 11.68]) compared to UKA. No significant differences were found between the compared groups in terms of VAS (MD= 0.14, 95% CI [-0.08, 0.36]), revision (OR= 1.30, 95% CI [0.65, 2.60]), and free walking speed (MD= -0.05, 95% CI [-0.11, 0.00]).Conclusion This study showed that UKA achieved fewer complications, better functional outcomes, and less range of motion compared to HTO. No significant differences were detected between HTO and UKA in terms of VAS and revision rate.

Purpose This study investigated the impact of chemotherapy on complication rates of implant and free flap breast reconstruction. The effect of timing and dosage of chemotherapy in minimizing the breast reconstruction surgery (BRS) complications were also investigated. Methods PRISMA guidelines were used to search relevant studies published from January 2009 to September 2021. Quality of selected studies were assessed using GRADE assessment and risk of bias was performed using Cochrane Collaboration’s tool and ROBINS-I. Rates of major and minor complications of neoadjuvant systemic therapy (NST) and adjuvant systemic therapy (AST) were compared by t-test using GraphPad Prism v.9.3.0 and P value P=0.4) In all studies, total complication rates for post-chemotherapy BRS patients was 46.03% compared to 32.49% without chemotherapy (P=0.09). Overall major complications rate was 14.5% (P=0.61) with NST and 21.1% (P=0.69) with AST. Minor complications rate was 28.8% (P=0.97) with NST and 39.5% (P=0.59) with AST. Complication rate of NST was lower than AST, but not statistically significant (P=0.64). No significant correlation was found between timing/duration of chemotherapy and rates of BRS complications (P=0.76). Conclusion No significant difference in BRS complications with and without chemotherapy was established. Despite these results suggesting little difference between NST and AST or chemotherapy in BRS complications, prospective control studies are currently limited, and more are necessary to better inform surgeons and their patients.

To investigate association between keratoconus and allergic eye diseases, eye rubbing, and atopy.PubMed, Web of Science, Scopus, and Cochrane were searched for relevant published studies from inception to April 2021 without restrictions or filters. We included case-control, cohort, and cross-sectional studies that investigated eye allergy, atopy, or eye rubbing as possible risk factors for KC. Two authors independently screened all titles and abstracts against predefined inclusion and exclusion criteria. This study analysed keratoconus prevalence and risk factors including eye rubbing, family history of keratoconus, atopy, and allergic eye diseases. The National Institute of Health Study Quality Assessment tool was utilised. Pooled data were presented as odds ratio (OR) and 95% confidence intervals (CI). Analysis was conducted using RevMan version 5.3 software.Out of 573 articles, we excluded 161 duplicates than 361 articles by title and abstract screening. The remaining 51 articles underwent full-text screening, and 29 articles were excluded. Twenty-one studies were included in the qualitative synthesis and fifteen for quantitative synthesis. There was no significant association found between KC and allergic eye diseases (OR = 1.03, 95% CI [0.96, 1.11], p = 0.45), eye rubbing (OR = 1.59, 95% CI [0.70, 3.63], p = 0.27), or atopy (OR = 1.08, 95% CI [0.80, 1.44], p = 0.62).No significant association was observed between KC and allergic eye disease, eye rubbing, or atopy. Further prospective studies are needed to clarify and validate these findings.

Purpose The aim of this study was to evaluate the diagnostic accuracy of 18 -fluorodeoxyglucose-positron emission tomography (18 F-FDG PET) and PET/computed tomography (PET/CT) in imaging primary and metastatic lesions in Ewing sarcoma (ES). Methods PubMed, Cochrane, Scopus, and Web of Science were searched for relevant studies. Data concerning 18 F-FDG PET/CT diagnostic accuracy were extracted and then analyzed using Open Meta-analyst software. Reported diagnostic accuracy outcomes included sensitivity, specificity, negative likelihood ratio (NLR), positive likelihood ratio (PLR), and diagnostic odds ratio. Results Thirty-one studies with a total of 735 patients were included in this meta-analysis. The sensitivity and specificity of 18 F-FDG PET/CT were: 92.6% and 74.1% for total ES lesions, 96.7% and 68.3% for ES primary lesions, 76.1% and 92.4% for lung metastasis, 83.9% and 93.2% for bone metastasis, and 89.9% and 92.6% for ES recurrence, respectively. Conclusion 18 F-FDG PET/CT is sensitive and accurate in diagnosing, staging, and detecting the recurrence of ES compared with non-PET imaging. It has high accuracy for diagnosing recurrence of ES in bone metastases; however, CT remains a superior diagnostic method for detecting lung metastasis.

PURPOSE: High tibial osteotomy (HTO) and unicompartmental knee arthroplasty (UKA) are commonly performed procedures for the treatment of compartmental knee osteoarthritis; however, the optimal procedure remains controversial. We conducted this systematic review and meta-analysis to compare the functional outcomes and assess complications and revision rates between the two techniques. METHODS: We searched electronic databases for relevant studies comparing HTO versus UKA for unicompartmental knee osteoarthritis. Continuous data as visual analogue scale (VAS), range of motion, and free walking speed were pooled as mean differences (MDs). Dichotomous data as functional knee outcomes, complications, and revision were pooled as odds ratios (ORs), with 95% confidence interval (CI), using R software for windows. RESULTS: Twenty-five studies involving 8185 patients were included. Meta-analysis showed that HTO was associated with higher risk of complications (OR = 2.47, 95% CI [1.52, 4.04]), poorer functional results (excellent/good) (OR = 0.32, 95% CI [0.21, 0.49]), and greater range of motion (MD = 7.05, 95% CI [2.41, 11.68]) compared to UKA. No significant differences were found between the compared groups in terms of VAS (MD = 0.14, 95% CI [− 0.08, 0.36]), revision rates (OR = 1.30, 95% CI [0.65, 2.60]), and free walking speed (MD = − 0.05, 95% CI [− 0.11, 0.00]). CONCLUSION: This study showed that UKA achieved fewer complications, better functional outcomes, and less range of motion compared to HTO. No significant differences were detected between HTO and UKA in terms of VAS and revision rate. Treatment options should be personalized to each patient considering factors such as their age, activities of daily living, their body mass index, and severity of osteoarthritis.
