The Application of Sodium Fluorescein in Resection of Medulloblastoma Under YELLOW 560 Filter: Feasibility and Preliminary Results of a Monocentric Cohort and Systematic Review.
BACKGROUND
Maximizing surgical resection of medulloblastoma (MB) affects overall survival; nevertheless, surgical resection remains a because of the infiltrative behavior of this tumor. Several dyes have been tested for improving tumor visualization; however, few reports with different protocols of fluorophores use are available and the results are inconsistent. Hence, we report our experience with sodium fluorescein in MB surgery, aiming to assess the role of this technique on the extent of resection. Furthermore, we performed a literature review of this topic.
METHODS
Fluorescence characteristics, extent of resection, and clinical outcome were analyzed in 9 consecutively operated patients with MB. A comprehensive literature search and review for English-language articles concerning fluorescein application in MB was conducted.
RESULTS
In our cohort, no side effect related to fluorescein occurred; all tumors presented with an intense or moderate yellow-green enhancement, and fluorescein was judged fundamental in distinguishing tumors from viable tissue in 7 of 9 cases. Gross total resection or near-total resection (i.e., a residual tumor volume <1.5 cm) was achieved in 8 patients. The review explored the different techniques and surgical interpretations as well as surgical radicality; we did not find a homogenous protocol for fluorescein injection in the published articles. Fluorescence appeared moderate or intense in almost all cases, with a high percentage of usefulness and consensual achievement of a high rate of gross total resection.
CONCLUSIONS
Based on these results, we can infer that fluorescein-guided surgical resection is a safe and valuable method for patients with MB.

BACKGROUND
The gold standard for sentinel lymph node staging in melanoma is the use of the combined technique of radioisotope plus blue dye. New techniques and alternative methods have been proposed, with the promise of achieving comparable efficacy. We then carried out a literature search.
METHODS
We conducted a literature search using the "sentinel lymph node biopsy" and "melanoma" keywords, then selected the case-control studies (the quality of which was assessed using the STROBE criteria).
RESULTS
Twelve studies of 13,017 were selected, concerning the identification rate of indocyanine green fluorescence and indocyanine green-99mtc-nanocolloid techniques. We have found a comparable identification rate between the various techniques, even if given the small population present for some techniques, the results did not reach statistical significance.
CONCLUSIONS
The use of new techniques in sentinel lymph node detection promises results comparable to the gold standard techniques, but further studies are needed to validate these methods in the context of melanoma surgery.

Meta-Analysis Review
Pulsed dye laser (PDL) is the most commonly used method for port-wine stain (PWS); however, no studies have reported the safety of PDL. This review aimed to collect and summarize complications reported in relevant literature, assess complication rates in treating PWS with PDL, and explore the relevant influencing factors. A systematic review and meta-analysis were conducted to search for related studies in PubMed, Embase, and the Cochrane Library until August 2022. Two reviewers independently evaluated the risk of bias of included studies. Stata Software version 17.0 was used for the analysis. All complications reported in the literature are divided into acute phase complications and long-term complications. Overall pooled purpura, edema, crusting, blistering, hyperpigmentation, hypopigmentation, and scarring rates were 98.3%, 97.6%, 21.5%, 8.7%, 12.8%, 0.9%, and 0.2%, respectively. Although the acute adverse reactions were found to be common, the long-term permanent complications clearly have a lower frequency, and the occurrence of scarring is much lower than that initially thought. This indicates that effective protective measures after treatment are very important for preventing scar formation. Overall, PDL treatment for PWS shows a high level of safety and low chances of causing long-term complications.

Meta-Analysis Review
Intradural spinal tumors present significant challenges due to involvement of critical motor and sensory tracts. Achieving maximal resection while preserving functional tissue is therefore crucial. Fluorescence-guided surgery aims to improve resection accuracy and is well studied for brain tumors, but its efficacy has not been fully assessed for spinal tumors. This meta-analysis aims to delineate the efficacy of fluorescence guidance in intradural spinal tumor resection. The authors performed a systematic review in four databases. We included studies that have utilized fluorescence agents, 5-aminolevulinic acid (5-ALA) or sodium fluorescein, for the resection of intradural spinal tumors. A meta-analysis was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A total of 12 studies involving 552 patients undergoing fluorescence-guided intradural spinal tumor resection were included. Meningiomas demonstrated a 98% fluorescence rate and were associated with a homogenous florescence pattern; however, astrocytomas had variable fluorescence rate with pooled proportion of 70%. There was no significant difference in gross total resection (GTR) rates between fluorescein and 5-ALA (94% vs 84%, p = .22). Pre-operative contrast enhancement was significantly associated with intraoperative fluorescence with fluorescein. Intramedullary tumors with positive intraoperative fluorescence were significantly associated with higher GTR rates (96% vs 73%, p = .03). Utilizing fluorescence guidance during intradural spinal tumor resection holds promise of improving intraoperative visualization for specific intradural spinal tumors. Meningiomas and ependymomas have the highest fluorescence rates especially with sodium fluorescein; on the other hand, astrocytomas have variable fluorescence rates with no superiority of either agent. Positive fluorescence of intramedullary tumors is associated with a higher degree of resection.

Review
There is increasing demand for natural and sustainable products for the treatment of dermatologic conditions. This systematic review aims to critically analyze published randomized controlled trials (RCTs) and provide evidence-based recommendations on the therapeutic use of curcumin for a variety of dermatological diseases. A systematic search of published literature was performed on July 18, 2023 using PRISMA guidelines for turmeric or curcumin for the treatment of skin diseases. Clinical recommendations were made based on the Oxford Centre for Evidence-Based Medicine guidelines. We identified 18 original randomized controlled trials for use of turmeric or curcumin for psoriasis, radiation dermatitis, oral lichen planus, pruritis, vitiligo, tinea capitis, facial erythema, and scarring. Psoriasis, cesarean section scar, and pruritus received grade of recommendation B. Radiation dermatitis, oral lichen planus, vitiligo, tinea capitis, and facial redness received grade of recommendation C or D. Curcumin was demonstrated to have an excellent safety profile in all clinical trials analyzed. Further research is required to determine optimal dosing and treatment parameters of turmeric. Additional, larger, RCTs and non-RCTs should be conducted to further investigate the safety and efficacy of curcumin as a treatment option for dermatological diseases.

Review
PURPOSE
To comprehensively review the efficacy and safety of OC-01 varenicline nasal spray versus vehicle nasal spray (VNS) in the treatment in dry eye disease (DED).
METHODS
A systematic review that included full-length randomized controlled studies (RCTs), as well as post hoc analyses of RCTs reporting new findings on OC-01 VNS treatment in three databases, PubMed, Scopus and Web of Science, was performed according to the PRISMA statement. The search period included studies published between December 2021 and September 2023. The Cochrane risk of bias tool was used to analyze the quality of the studies selected.
RESULTS
A total of 8 studies were included in this systematic review. OC-01 VNS treatment achieved higher improvement than vehicle in all reported variables. The mean differences between both groups were in favor of OC-01 VNS treatment and were as follow: eye dryness score base on a visual analogue scale (EDS-VAS) of -7.5 ± 2.2 points [-11.6 to -5.6], Schirmer test (ST) with anesthesia of 6.6 ± 2.3 mm [4.9 to 11.8] and total corneal fluorescein staining (tCFS) of -1.2 ± 0.01 points [-1.2 to -1.1]. Similar improvements were reported with OC-01 VNS 0.03 mg and 0.06 mg. Adverse events (AEs) were 15.5 ± 19.4 % [-13 to 80.5] higher in the OC-01 VNS group with an overall adherence > 93 %.
CONCLUSIONS
OC-01 VNS improves dry eye symptoms and signs with a satisfactory tolerability. Therefore, OC-01 VNS seems to be a safe and effective treatment that could be recommended in patients with DED. This new treatment could be particularly useful in those patients who have difficulties with the administration of traditional topical therapies.

Meta-Analysis Review
The objective was to evaluate the efficacy of curcumin in improving mouth opening (MO), burning sensation (BS), and tongue protrusion (TP) symptoms in patients with oral submucous fibrosis (OSF). An electronic search up to November 2022 was conducted in the PubMed, Web of Science, Embase, EBSCO, ProQuest, and Cochrane Library databases to identify studies using curcumin in the treatment of OSF with comparison to control groups (drugs previously proven to be effective for OSF treatment) or placebo. Only randomized controlled trials (RCTs) were considered. RevMan 5.3 software was used for the meta-analysis. Thirteen RCTs met the eligibility criteria and were included in the analysis. The results showed no significant improvement in MO (in millimetres) for curcumin when compared to control at 1 month (P = 0.91), 2 months (P = 0.54), 3 months (P = 0.56), or 6 months (P = 0.17) of treatment. There was no significant difference in BS (assessed using a visual analogue scale) between curcumin and control after 1 month (P = 0.05), 2 months (P = 0.64), 3 months (P = 0.13), or 6 months (P = 0.56) of treatment. Compared with the control groups, treatment with curcumin for 1 month (P = 0.32), 2 months (P = 0.07), and 3 months (P = 0.14) did not significantly improve the TP (in millimetres) of patients. The administration of curcumin, whether topically applied or taken orally, did not confer statistically significant improvements in MO, BS, or TP in comparison to the control treatments, among patients with OSF. The results of this meta-analysis showed that compared to placebo, the application of curcumin for 6 months markedly alleviated BS (P < 0.001). Curcumin treatment in OSF reaches a clinically effective range, but more bioavailability-centred outcomes should be reported. Robust multicentre RCTs are warranted to elucidate the efficacy of curcumin in improving specific outcomes like MO, BS, and TP in patients with this condition. Defining the therapeutic role of this natural compound may provide an effective botanical alternative for managing OSF.

Review
BACKGROUND
The main objective of this systematic review was to evaluate the effect of coating with titanium dioxide nanoparticles (TiO nanoparticle) on the surface condition of removable acrylic resin prosthetic base materials.
METHODS
Our review is registered in the PROSPERO database under the identification code CRD42023397170. Electronic database searches of PubMed, Scopus and Science Direct including studies from January 2009 to January 2023 were conducted and supplemented with manual searches. Research questions were generated in accordance with the PICO strategy. The modified Consolidated Standards of Reporting Trials (CONSORT) checklist was used to evaluate the quality of the selected studies.
RESULTS
Since the included studies were variable in design, a meta-analysis was not performed. The electronic searches retrieved 29 references that met the eligibility criteria, among which 5 studies matched the inclusion criteria for this review. Significant differences were detected between the TiO NP-coated and uncoated groups. The available data indicate that TiO NP coating elicits antimicrobial activity and improves the wear resistance of polymethylmethacrylate (PMMA) surfaces. Moreover, the nanoparticles provide high levels of glossiness and decelerate the process of color change of heat-cured acrylic resin, thus increasing the lifespan of dentures.
CONCLUSION
The collective results clearly indicate that TiO nanoparticle coating induces alterations in the surface properties of pure PMMA, enhancing the mechanical, physical and biological characteristics of the denture base material. Further studies are essential to identify the optimal thickness of coating and concentrations of nanoparticles for clinical applications.

Meta-Analysis
BACKGROUND
Indigo naturalis (Qing dai) is a traditional therapy reported to be useful in inflammatory bowel disease (IBD), especially for ulcerative colitis. We performed a systematic review of its efficacy and safety in IBD.
METHODS
Electronic databases (Pubmed, Embase, and Scopus) were searched on 4th March 2023 to identify reports about the use of indigo naturalis in IBD. We extracted data with respect to clinical response, remission, endoscopic and histological responses, and adverse events with the use of indigo naturalis in IBD. Pooled clinical response rates and remission rates were calculated. The quality of studies was assessed using Joanna-Briggs tools.
RESULTS
Nine studies reporting on 299 patients were included. The pooled clinical response rate was 0.796 (95 %CI, 0.7465-0.8379, I2=0), and the clinical remission rate in ulcerative colitis was 0.668 (0.488- 0.809, I=85.2 %). The pooled relative risk of clinical response was higher in the indigo naturalis group as compared to placebo in the two randomized trials [3.82 (2.04; 7.14, I=0)]. Except for one reversible pulmonary arterial hypertension case, most reported adverse effects were mild. The endoscopic and histological responses, when reported, suggested that indigo naturalis is effective for ulcerative colitis. The limitations of the systematic review included a small number of randomized studies, reports only from East Asia and a relatively small number of patients, especially for Crohn's disease.
CONCLUSION
Indigo naturalis is effective in the treatment of ulcerative colitis. Future studies should evaluate the comparative efficacy with other drugs.

Meta-Analysis
Comparison of perioperative outcomes of selective arterial clipping guided by near-infrared fluorescence imaging using indocyanine green versus undergoing standard robotic-assisted partial nephrectomy: a systematic review and meta-analysis.
BACKGROUND
This study employs a meta-analytic approach to investigate the impact of robotic-assisted partial nephrectomy, with and without near-infrared fluorescence imaging (NIRF-RAPN vs S-RAPN), on patients' perioperative outcomes and postoperative changes in renal function.
MATERIALS AND METHODS
The authors conducted a comprehensive and rigorous systematic review and cumulative meta-analysis of primary outcomes following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), AMSTAR (Assessing the Methodological Quality of Systematic Reviews) Guidelines, and Risk-of-Bias Tool (RoB2). To ensure a thorough search, the authors systematically searched five major databases, including Medline, PubMed, Cochrane Library, Scopus, and Web of Science, from databases' inception to April 2023.
RESULTS
No significant differences were found between the two groups in terms of age ( P =0.19), right side ( P =0.54), BMI ( P =0.39), complexity score ( P =0.89), tumor size ( P =0.88), operating time ( P =0.39), estimated blood loss ( P =0.47), length of stay ( P =0.87), complications ( P =0.20), transfusion ( P =0.36), and positive margins ( P =0.38). However, it is noteworthy that the NIRF-RAPN group exhibited significant reductions in warm ischemia time ( P =0.001), the percentage change in estimated glomerular filtration rate at discharge ( P =0.01) compared to the S-RAPN group.
CONCLUSION
This meta-analysis provides evidence that the group undergoing NIRF-RAPN showed a statistically significant protective effect on the estimated glomerular filtration rate (eGFR).
