Meta-Analysis Review
This systematic review aims to update current evidence on the efficacy and safety of photodynamic therapy (PDT) and anti-vascular endothelial growth factor (anti-VEGF) injections for acute central serous chorioretinopathy (CSC). A comprehensive literature search was conducted in PubMed, EMBASE, and Cochrane Library. Studies comparing (1) PDT versus placebo, (2) anti-VEGF versus placebo, and (3) PDT versus anti-VEGF were included and meta-analyzes were performed when appropriate. Ocular and systemic adverse effects were also summarized. Literature search yielded six comparative studies, among which five were included for this review. Meta-analysis with three studies indicated that eyes treated with PDT achieved better best-corrected visual acuity (BCVA) and central macular thickness (CMT) than the placebo group throughout a follow-up of 12 months. Meta-analysis with another two studies comparing anti-VEGF injections and placebo showed that BCVA at first month was better in anti-VEGF group than in placebo group, though the differences of BCVA and CMT no longer existed at 3 and 6 months after injection. There was no report directly comparing PDT and anti-VEGF for acute CSC. No severe complications was reported in included studies. In this review, current evidence suggested that early treatment of acute CSC by PDT is valuable in improving visual acuity, reducing subretinal fluid, and maintaining long term effectiveness. Anti-VEGF injection could shorten the duration of symptoms and accelerate visual improvement at early stage of disease. Direct comparison between these two treatment will be needed in the future.

Meta-Analysis Review
Central serous chorioretinopathy (CSC) is a prevalent exudative maculopathy and the ongoing verteporfin shortage restricts current treatment possibilities. Topical non-steroidal anti-inflammatory drugs (NSAID) have previously been proposed as a treatment for CSC, although its exact efficacy remains unclear. In this systematic review and meta-analysis, we outlined the efficacy of topical NSAIDs for the treatment of CSC. We searched 11 literature databases on 13 December 2022, for any study describing topical NSAID treatment for CSC. Thirteen eligible studies were included with a total of 1001 eyes of 994 patients with CSC. Six studies were case reports, two were cohort studies and five were non-randomized comparative studies. Where specified, topical NSAIDs used were bromfenac 0.09%, diclofenac 0.1%, ketorolac 0.4% and 0.5%, pranoprofen 0.1%, and nepafenac 0.1% and 0.3%. Studies were predominantly of cases with acute CSC and several case studies reported treatment outcomes simultaneously with discontinuation of corticosteroid use, which complicated treatment evaluation. Meta-analyses of comparative studies revealed a statistically significant but clinically irrelevant best-corrected visual acuity improvement of -0.04 logMAR (95% CI: -0.07 to -0.01 logMAR; p = 0.01) at 1-month follow-up, which became statistically insignificant at 3-month follow-up (-0.03 logMAR; 95% CI: -0.06 to 0.003 logMAR; p = 0.08). Further, we found no benefit in complete subretinal fluid resolution at 1-month follow-up (OR: 1.20; 95% CI: 0.81-1.76; p = 0.37) or 3-month follow-up (OR: 1.17; 95% CI: 0.86 to 1.59; p = 0.33). Taken together, available evidence does not support the use of topical NSAIDs for the treatment of CSC.

Phycobiliprotein is a natural product with many biological activities in various seaweeds. Phycobiliproteins have been widely used for anti-oxidation, anti-tumor, anti-inflammatory and immune-enhancing activities as a functional factor. Phycobiliproteins with high purity are considerably more expensive than common. To provide with a systematic, deep and detailed information about those features of phycobiliproteins, we performed a relatively comprehensive analysis on structural composition, the application of phycobiliproteins in the fields of fluorescent probe and photodynamic therapy in this report.

Meta-Analysis Review
OBJECTIVES
To evaluate the effectiveness of Photodynamic Therapy (PDT) in the treatment of Oral Potentially Malignant Disorders (OPMDs) patients.
METHODOLOGY
An electronic search was conducted to retrieve articles published until September 2021. Meta-analyses were conducted for the outcomes of complete response (CR) and any response (AR) after treatment with PDT using data from single-arm studies, case series and non-randomised controlled trials (NRCTs).
RESULTS
In total, 49 articles were included. RCTs revealed insignificant mean difference (MD) in efficacy index between PDT and comparison groups (MD: 1.32; 95% CI:-28.10-30.72, p=0.930). The likelihood of CR (OR:0.84; 95% CI: 0.42-1.71, p=0.637) or AR (OR:2.10; 95% CI: 0.31-14.25, p=0.448) was not different in PDT group when compared with any comparison treatments in NRCTs. CR/AR among single arm studies was 60.6% (95% CI: 50.5-70.7, P<0.001) and 93.7% (95% CI:91.5-95.8, P<0.001) respectively. Higher prevalence of CR and AR was observed for dysplasia or carcinoma insitu (CIS) (CR: 81%, 95% CI: 70.8-91.3, P<0.001; AR: 94.3%; 95% CI: 89-99.6, P<0.001) and actinic cheilitis (AC) (CR: 73.9%, 95% CI: 65.9-81.9, P<0.001; AR:97%; 95% CI:94.9-99, P<0.001).
CONCLUSIONS
More than half of the patients receiving PDT showed CR, with more than 90% responding to the treatment. PDT was most effective on oral dysplasias, followed by AC.

Meta-Analysis Comparative Study
Corneal crosslinking (CXL) is used for treating keratoconus and post-laser in situ keratomileusis ectasia. However, refractive surgery is not usually performed with prophylactic CXL. Therefore, we performed a meta-analysis comparing outcomes of refractive surgeries with vs without prophylactic CXL. We systematically searched databases for studies comparing refractive surgeries for myopic correction with vs without prophylactic corneal crosslinking. Review Manager 5.4.1 was used to perform statistical analysis. We included 2820 eyes from 28 studies. Compared with refractive surgery alone, surgery with prophylactic CXL resulted in decreased central corneal thickness, corrected distance visual acuity logMAR, and safety and efficacy indices. There were no significant differences in postoperative uncorrected distance visual acuity of 20/20 or better at ≥12 months and other visual outcomes among both groups. More randomized controlled trials with standard crosslinking protocols are needed to analyze the prophylactic use of crosslinking with refractive surgeries.

Review
BACKGROUND
Noninvasive procedures for facial rejuvenation are becoming an increasingly popular component of a comprehensive skin care regimen. Concurrently, many new treatment methods are now available to both the plastic surgeon and the aesthetician. Because these techniques have become an integral part of many cosmetic practices, this study aimed to assess the existing evidence-based literature as to their clinical efficacy; to provide an objective overview of some of the most popular noninvasive rejuvenation strategies such as dermaplaning, oxygen therapy, and light therapy; to discuss recent pertinent scientific evidence-based literature; and to provide treatment recommendations based on these findings.
METHODS
A systematic review was performed in August 2009 using PubMed and the following keywords: "dermaplaning," "oxygen therapy," and "light therapy." All peer-reviewed articles then were screened independently by three plastic surgeons.
RESULTS
The search identified 42 English-written, peer-reviewed manuscripts. The overall amount of scientific data supporting these methods was found to be scarce, anecdotal, and not well documented. Nevertheless, all three noninvasive therapies have become increasingly popular in the cosmetic market because many patients and physicians or surgeons report being pleased with their results.
CONCLUSION
Although the evidence supporting these nonsurgical methods is suboptimal, their uses continue to expand. As with any plastic surgery procedure, providing patients with realistic expectations is essential to achieving optimal outcomes and patient satisfaction. Therefore, critical investigation is warranted. In addition, these methods are most effective when included within a comprehensive skin care regimen consisting of sunscreen, vitamin therapy, and lifestyle modification.

Clinical and Radiographic Outcomes of Adjunctive Photodynamic Therapy for Treating Peri-Implant Mucositis Among Cigarette Smokers and Diabetics: A Systematic Review and Meta-Analysis.
This systematic review aimed to assess the influence of antimicrobial photodynamic therapy (aPDT) as an adjunct to mechanical debridement (MD) on peri-implant clinical and radiographic outcomes among cigarette smokers and diabetics with peri-implant mucositis (piM). Randomized controlled trials, assessing the clinical and radiographic parameters of aPDT versus MD alone among smokers and diabetics with piM, were included in the study. Meta-analyses were conducted to calculate the standard mean difference with a 95% confidence interval. The methodological quality of the included studies was assessed utilizing the modified Jadad quality scale. The meta-analyses found statistically significant differences between the impact of adjunct aPDT and MD alone on the peri-implant plaque index (PI), probing depth (PD), and bleeding on probing among smokers and diabetics with piM at the final follow-up visit. However, no significant differences were found between the impact of adjunct aPDT and MD alone on the peri-implant crestal bone loss among smokers and diabetics with piM at the final follow-up. The application of aPDT as an adjunctive to MD demonstrated improved scores of the peri-implant clinical parameters among smokers and diabetics with piM in comparison with MD alone.

Review
Oral cancer represents an important health problem, as it is the sixth most common type of cancer in the world and is associated with high rates of morbidity and mortality. The treatment considered the gold standard for this type of tumor is surgical resection with negative margins, with a distance of at least 5 mm from the tumor. This procedure is strongly associated with local control and disease-specific survival, however, in many cases, large amounts of healthy tissue are removed, resulting in surgical defects, compromising various functions and directly affecting the individual's quality of life. From this perspective, this systematic review aimed to evaluate the use of autofluorescence and fluorescent probes as potential adjuvant techniques to facilitate the delineation of surgical margins for oral cancers. A comprehensive search was performed in Pubmed, Scopus, Web of Science, LIVIVO, Embase, ProQuest Open Access Dissertations & Theses, Open Access Theses and Dissertations, and DART Europe databases, where 1948 articles were found. After the different stages of critical evaluation, 15 articles were selected, eligible for the inclusion criteria. Of these, 7 articles used autofluorescence, 7 used fluorescent probes and 1 article used both methods. As for autofluorescence, the most used device was the VELScope, and indocyanine green was the most used probe. Compared to histopathology, autofluorescence did not obtain significant and/or superiors results. In contrast to fluorescent probes that, most articles showed a good performance of margins during surgical resection, making them a promising alternative. However, it is still necessary to carry out the analysis of more articles, with more significant samples and sensitivity and specificity data to qualify the results.

Meta-Analysis Review
BACKGROUND
To determine whether treatment with antimicrobial photodynamic therapy (aPDT) as an adjunct to scaling and root planing (SRP) yield better clinical periodontal outcomes than antibiotics (AB) as adjunct to SRP in periodontitis.
METHODS
Electronic searches were conducted in databases (MEDLINE, PubMed, EMBASE, SCOPUS, Cochrane Central Register of Controlled Trials and Cochrane Oral Health Group Trials Register databases) up to and including April 2017.
RESULTS
Five randomized trials were included. All studies used the combined approach aPDT+SRP and AB+SRP in the test and control group respectively. The follow up period ranged from 12 to 48 weeks. All studies used diode lasers. The wavelengths, power density and duration of irradiation used were 670 nanometre, 75 milliwatts per square centimeters and 60s respectively. None of the studies showed additional benefits of aPDT at follow up. Considering the effects of adjunctive aPDT as compared to AB, a high degree of heterogeneity for periodontal probing depth (PPD) (p<0.0001, I=87.47%) was noticed among both the groups. Meta-analysis showed significant clinical attachment level (CAL) gain (WMD=0.60, 95% CI=0.25 to 0.95, p=0.001), and not PPD reduction (WMD=0.67, 95% CI=-0.36 to 1.71, p=0.204) for aPDT as compared to AB at follow up.
CONCLUSION
It remains debatable whether aPDT is more effective as compared to adjunctive AB in the treatment of periodontitis, given that the scientific evidence is weak. Precautions must be exercised when interpreting the results of this study due to the small sample size and high heterogeneity among studies.

Meta-Analysis Review
Oral potentially malignant disorders (OPMD) represent a group of lesions with increased risk for malignant transformation. The management of such injuries is based on surgical treatment or detailed follow-up throughout the patient's lifetime. This systematic review and meta-analysis investigated and critically evaluated the use of autofluorescence and fluorescent probes as potential techniques for the early detection of OPMD. A comprehensive search was performed on Pubmed, Scopus, Web of Science and LIVIVO databases. The gray literature was also consulted and included Google Scholar, Proquest and Open gray databases. 2715 articles were retrieved, and after the different stages of critical evaluation, were reduced to 25 articles that fully met the inclusion criteria. VELscope® was the most used equipment for autofluorescence, while aminolevulinic acid (5-ALA) was the main representative of the probes. The meta-analysis performed included 10 articles that used VELscope® as a method to detect oral disorders. A 95% confidence interval (CI) with a p value significance <0.05 was considered as a criterion for the statistical analysis. The combined sensitivity was 74% (CI95 60-76%, p = 0.0001) and the specificity was 57% (CI95 52-60%, p = 0.0000). The inclusion of these adjunct methods in clinical practice is very promising, since they are able to help both the clinician and the specialist in the early detection of potentially malignant oral disorders, favoring a better prognosis. However, it is still necessary to carry out further studies, with the aim of establishing a protocol for use and qualification of results.
