Abstract
Onychomycosis, a fungal infection of the nails, presents a significant challenge in clinical management due to its chronic nature and resistance to conventional therapies. This study aims to evaluate the efficacy of laser therapy in treating onychomycosis compared to traditional methods such as terbinafine. A systematic review and meta-analysis were conducted to analyze existing literature on the subject. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) diagram illustrates the selection process of studies. Findings suggest that laser therapy demonstrates promising results in the treatment of onychomycosis, with comparable efficacy to terbinafine and fewer adverse effects. Further large-scale randomized controlled trials are warranted to validate these findings and establish laser therapy as a standard treatment option for onychomycosis.

Abstract
Introduction Onychomycosis is a common nail disorders. Antifungal resistance, interactions, and side effects limit treatment options. Fractional CO2 (FCO2) laser along with topical antifungal is effective in multiple monthly sessions. A modification reducing repeated visits and hence better compliance is preferable. Single-session FCO2 laser following urea occlusion is reported to be effective. Thus, we conducted a study to determine the efficacy of single-session FCO2 laser with 1% terbinafine cream with and without "urea cream occlusion" in managing onychomycosis. Methods A prospective, randomized, parallel-group study was conducted at a tertiary centre. Onychomycosis was confirmed by positive fungal mount and culture. Patients were randomized into 2 groups and administered single-session FCO2 laser. Group A was treated after overnight urea cream occlusion and group B without occlusion. Both groups applied 1% terbinafine cream twice daily for 3 months. Response was assessed by improvement in Onychomycosis Severity Index (OSI) at 6 months. Results Group A had 10 patients, 14 nails. Clinical improvement was seen in 12/14 (85.7%) nails. Average reduction in OSI was 10.78. Group B had 10 patients, 11 nails. Clinical improvement was seen in 5/11 (45.5%) nails. Average reduction in OSI was 1.73. "Reduction in OSI" was statistically significant (p < 0.05) only in group A. Conclusion Single-session FCO2 laser following overnight urea cream occlusion, followed by 1% terbinafine cream, is effective for management of onychomycosis.

Abstract
Onychomycosis is a fungal infection of the nail unit caused by various species of dermatophytes, non-dermatophytic moulds or yeasts. They pose a therapeutic challenge to the treating dermatologist as the infection is often resistant to treatment and requires prolonged therapy. To evaluate the efficacy and safety profile of fractional CO2 laser and 0.25% Amorolfine hydrochloride cream in the treatment of onychomycosis. In this randomized controlled study on 50 patients with fingernail onychomycosis, one group (25 patients, 30 nails) were treated with fractional CO2 laser and 0.25% Amorolfine hydrochloride cream, and the second group (25 patients, 31 nails) with oral itraconazole pulse therapy. Four treatment sessions were carried out in the first group at an interval of two weeks each. Whereas, the second group received 2 doses of itraconazole pulse therapy with one month interval each. Both the groups were followed up for a period of 4 months. Results were assessed by Onychomycosis severity index(OSI), Physician global assessment scale, patient's subjective score and fungal microscopy. Complete resolution was seen in 14 out of 25(56%) patients and 6 out of 25(24%) patients in group 1 and group 2 respectively. There was statistically significant difference in the response between the two groups during 1st and 2nd follow up (p value - 0.004 and 0.023 respectively). Fractional CO2 laser with amorolfine cream is proved to be a better modality in onychomycosis therapy compared to oral itraconazole pulse therapy, especially in distal lateral subungual and superficial white onychomycosis.

Abstract
Keratolytic properties of urea 40% have long time used for the treatment of onychomycosis. Fractional ablative lasers enhance the delivery of topically applied photosensitizers improving photodynamic therapy (PDT) efficacy. The aim of this study was to compare the short- and medium-term efficacy of a pretreatment with urea 40% and fractional Er:YAG (Fr Er:YAG) laser radiation before PDT mediated by methylene blue (MB) for moderate toenail onychomycosis. Twenty-first-toe toenails were randomized to receive either urea 40% (Group I) or Fr Er:YAG laser (Group II) pretreatment and 9 sessions of MB/PDT over the course of 16 weeks. At baseline, 28- and 40-week follow-ups, clinical efficacy was assessed by digital photographs [allowing determination of the onychomycosis severity index (OSI)], whereas mycological efficacy was assessed by histological examination and fungal culture. Details of the side effects and patients' satisfaction were also recorded. In both groups, a significant decrease in OSI values was observed at the 28-week follow-up and a slight rebound at the 40-week follow-up. The percentage of nail involvement decreased significantly in both groups at the 28-week follow-up, to continue declining gently in Group I at 40 weeks, in contrast to the rebound observed during this period in Group II. The mycological cure rate was 20% and 30% at 28-week follow-up and 70% and 40% at 40-week follow-up, in Group I and II, respectively. Patients reported being fairly satisfied, and no side effects were detected in any groups. Although both pretreatments favor the action of PDT for the treatment of onychomycosis, the use of urea at 40% is more effective in the medium term.

Abstract
Background Onychomycosis accounts for 20-40% of all nail disorders. It is difficult to cure with resistance to anti-fungal drugs, their side effects and drug interactions limiting treatment options. Itraconazole is a widely accepted oral medication used for onychomycosis while fractional CO2 laser along with a topical anti-fungal has shown promising results for nail plate clearance in onychomycosis. Aim To compare the efficacy of fractional CO2 laser with 1% terbinafine cream versus itraconazole in the management of onychomycosis. Methods A prospective, randomised, single-centre, two-arm, parallel-group interventional study was conducted at Command Hospital Air Force, Bangalore. Onychomycosis cases confirmed by KOH mount/culture-positive were included. Patients were randomly divided into two groups. Group A received 4 sessions of fractional CO2 laser every fourth week with twice-daily application of 1% terbinafine cream; Group B received one-week pulse therapy with capsule itraconazole once every four-week for three pulses. The response was assessed by Onychomycosis Severity Index, a validated onychomycosis assessment scale, at baseline and at six months. Results Group A had 50 patients with a total of 98 nails. Clinical improvement was seen in 83/98 (84.7%) nails. The average reduction in Onychomycosis Severity Index was 8.65 (P < 0.05). Group B had 50 patients with a total of 136 nails. Clinical improvement was seen in 104/136 (76.5%) nails. The average reduction in Onychomycosis Severity Index was 7.37 (P < 0.05). Both groups showed statistically significant improvement measured by 'Reduction in Onychomycosis Severity Index' at six months; however, there was no significant difference between the two arms. Limitations The main limitations of the study are the small sample size and lack of long-term follow-up to assess recurrence of infection. Conclusion Fractional CO2 laser with 1% terbinafine cream is an effective and safe method for inducing nail clearance in onychomycosis and has efficacy similar to itraconazole pulse therapy.

Abstract
Onychomycosis (OM) is a fungal infection, responsible for about 50% of nail diseases. OM has been attributed to the ability of fungi to naturally organize themselves into biofilms on nail surfaces. However, little is known about the exact role of the biofilm in the etiopathogenesis of OM, as well as its influence in the permeation of a topical treatment. The objectives of this study were to review the literature for topical OM treatments in clinical trials, assess the efficiency of these treatments, and discuss factors that could affect the success of these treatments. First, a systematic search of articles published in the MEDLINE database (PubMed) between January 2010 and December 2019 was conducted, focusing on drugs under clinical trials for the topical treatment of OM. Of the publications selected, it was clear that none of them had considered the fungi organized in biofilm. Therefore, we reflected on some important variables involved in OM, such as the nail structure and the mechanism of fungal invasion. Some methods, such as histopathologic analysis and spectroscopy techniques, were found to be effective in the detection of nail biofilm, and could be used in future drug permeation studies. This review allowed us to conclude that novel antifungals for the topical treatment of OM must consider the drug to permeate through biofilm. Natural products, such as propolis, seem strong candidates in this respect.

Lasers Surg Med 2022; 54:861-874.

Abstract
Purpose Conventional oral antifungal therapies for onychomycosis (OM) often do not achieve complete cure and may be associated with adverse effects, medical interactions, and compliance issues restricting their use in a large group of patients. Topical treatment can bypass the systemic side effects but is limited by the physical barrier of the nail plate. Ablative fractional laser (AFL) treatment can be used to improve the penetration of topical drugs into the nail. This study visualized the effects of laser ablation of nail tissue and assessed their impact on the biodistribution of a fluorescent dye in healthy and fungal nail tissue. Methods For the qualitative assessment of CO2 AFL effects on healthy nail tissue, scanning electron microscopy (SEM), coherent anti‐Stokes Raman scattering microscopy (CARS‐M), and widefield fluorescence microscopy (WFM) were used. To quantitate the effect of laser‐pretreatment on the delivery of a fluorescent dye, ATTO‐647N, into healthy and fungal nail tissue, ablation depth, nail plate thickness, and ATTO‐647N fluorescence intensity in three nail plate layers were measured using WFM. A total of 30 nail clippings (healthy n = 18, fungal n = 12) were collected. An aqueous ATTO‐647N solution was directly applied to the dorsal surface of 24 nail samples (healthy n = 12, fungal n = 12) and incubated for 4 hours, of which half (healthy n = 6, fungal n = 6) had been pretreated with AFL (30 mJ/mb, 15% density, 300 Hz, pulse duration <1 ms). Results Imaging revealed a three‐layered nail structure, an AFL‐induced porous ablation crater, and changes in autofluorescence. While intact fungal samples showed a 106% higher ATTO‐647N signal intensity than healthy controls, microporation led to a significantly increased fluorophore permeation in all samples (p < 0.0001). AFL processing of nail tissue enhanced topical delivery of ATTO‐647N in all layers, (average increase: healthy +108%, fungal +33%), most pronounced in the top nail layer (healthy +122%, fungal +68%). While proportionally deeper ablation craters correlated moderately with higher fluorescence intensities in healthy nail tissue, fungal samples showed no significant relationship. Conclusion Fractional CO2 laser microporation is a simple way of enhancing the passive delivery of topically applied ATTO‐647N. Although the impaired nail plate barrier in OM leads to greater diffusion of the aqueous solution, AFL can increase the permeability of both structurally deficient and intact nails.

Abstract
BACKGROUND Current therapeutic agents for onychomycosis have limited efficacy or cause side effects. Recently, successful treatment using fractional CO2 lasers has been reported; however, the results are inconsistent. OBJECTIVE We analyzed the real-world effectiveness of a Fractional CO2 laser for the treatment of Onychomycosis METHODS: A single-center retrospective chart review was conducted during January 2015-December 2018. Patients, diagnosed with onychomycosis through fungal culture and/or potassium hydroxide staining, underwent three or more fractional CO2 laser treatments and used topical antifungal agents. Treatment effects were assessed by using clinical images at 6 months, 12 months, and the last visit. RESULTS Ninety-six patients were included; they underwent an average of 7.7 laser treatment sessions. Finally, 15 patents (15.6%) showed complete response (CR, 100% clearing of all nails), 24 patients (25%) showed partial response, and 57 patients (59.4%) showed no response (no 100% clearing of nails among all treated toenails per patient including mild improvement or temporary cosmetic improvement). Multivariable logistic regression analysis revealed longer disease duration (P=0.006, OR=1.16(95% CI: 1.05-1.31)), patients with diabetes (P=0.021, OR=9.82(95% CI:1.75-94.01)) and fewer number of laser treatment sessions (P=0.001, OR=0.76(95% CI:0.64-0.89)) were significantly associated with non-response group. CONCLUSIONS In conclusion, fractional CO2 laser with topical antifungal could be a safe alternative treatment in patients with onychomycosis, who are difficult to take oral antifungals.

Abstract
Onychomycosis is the most common nail disease encountered in clinical practice. Its importance extends well beyond aesthetics, often causing pain, difficulty with ambulation and performing daily activities, and impairing quality of life. Many patients fail to achieve cure with antifungal monotherapy and recurrences are common. Combination therapy has therefore gained considerable interest, given the potential for drug synergy and prevention of antifungal resistance, but it has not been well studied. A systematic review of onychomycosis medication only, as well as medication and procedural (laser, debridement, photodynamic therapy), clinical or randomized controlled trials evaluating combination vs. monotherapies was performed. After exclusions, 30 studies were included in the final analysis. There were conflicting results for medication-only trials, with some showing significant benefit of combination therapy over monotherapy, however, trials were not robustly designed and lacked sufficient follow-up. Procedural studies also lacked long-term follow-up, and failed to demonstrate efficacy in some severe onychomycosis cases. Considering the high cure rates demonstrated in pivotal antifungal monotherapy trials, and conflicting results, costs, and safety concerns associated with combination therapy, we recommend that combination therapy be reserved as second-line treatment options in patients with poor prognostic factors or for those who failed monotherapy for onychomycosis.

Abstract
Background Onychomycosis has always been a therapeutic challenge because of longer treatment duration, potential adverse effects of oral antifungals, and limited efficacy of topical agents. During the past few years, the emergence of laser therapy has been the topic of discussion as a newer, safe, minimally invasive modality of treatment. Aim The aim of this study was to evaluate the role of fractional CO2 laser and topical luliconazole 5% lotion in the treatment of onychomycosis, as a combined treatment and as independent modalities. Materials and Methods This was a prospective, randomized, triple-limb comparative observational study in which 106 patients with KOH and culture-proven onychomycosis were randomly assigned to three groups. Group A received fractional CO2 laser (10,600nm) triweekly for four sessions (0, 3, 9, and 12 weeks) plus topical luliconazole 5.0% lotion applied twice daily on the affected nail plates and nail folds for 12 weeks. Group B received only fractional CO2 with the same frequency of sessions and laser parameters as in group A. Group C received only topical luliconazole 5.0% solution twice daily for 12 weeks. Treatment outcome was evaluated using onychomycosis severity index (OSI) score, mycological parameters, and level of satisfaction of patients. Results The degree of clinical improvement, mycological cure, and patient's satisfaction was significantly better in the combined group than individual modalities. There were no severe adverse effects that warranted the discontinuation of the treatment in any of these patients. Conclusion Fractional CO2 laser combined with topical luliconazole 5% lotion is a safe and effective treatment for onychomycosis especially in those who have contraindications to oral antifungals.

Abstract
BACKGROUND Treatment of nail psoriasis is disappointing; due to poor penetrability of topical therapies and variable efficacy of systemic therapies. Fractional carbon dioxide laser (FCL) may enhance penetration of topical therapy for nail psoriasis. OBJECTIVE To evaluate the efficacy and safety of FCL plus topical tazarotene versus tazarotene monotherapy in the treatment of nail psoriasis. METHODS Twenty-seven patients with bilateral fingernail psoriasis randomly received 3 sessions of FCL at four-week interval plus once-daily tazarotene 0.1% gel for one hand, and once-daily tazarotene 0.1% gel only for 3 months on the other hand. The primary outcome was modified Nail Psoriasis Severity Index (mNAPSI) at 3 and 6 months compared to baseline, and the secondary outcomes included dermoscopic examination and patient global assessment. Adverse events were reported. RESULTS The total, nail matrix, and nail bed mNAPSI scores were significantly improved at 3 and 6 months by both regimens, but they decreased more after FCL/tazarotene combination (p = 0.001, p = 0.023, and p = 0.001, respectively). Combination therapy showed faster improvement of nail matrix signs and greater efficacy for nail bed signs. The dermoscopic features of the nail plate were the most responsive after both treatments. The combined therapy was more effective in improving the dermoscopic nail bed features. Patient's global assessment scores were significantly higher after the combined therapy. Both treatments were well tolerated. CONCLUSION Fractional CO2 laser is an effective and well-tolerated treatment for nail psoriasis; it improves the outcomes of topical tazarotene especially in nail bed lesions.

[PMID: 34538013 DOI: 10.1111/dth.15136] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Revised: 09/11/2021] [Accepted: 09/16/2021] [Indexed: 02/07/2023]
Abstract
The routine options for onychomycosis are oral, topical, and device-based therapies which are often limited in terms of efficacy and unsatisfactory side effects. Topical agents such as luliconazole, tioconazole, terbinafine, and tazarotene can be more effective when combined with laser therapies. Our aim was to compare the efficacy and satisfaction rates of CO2 laser therapy with topical agents in patients with onychomycosis. PubMed, the Cochrane Library, Embase, and Ovid databases were searched to identify randomized controlled trials (RCTs) evaluating the effects of combined therapies. Selected study data were analyzed for differences expressed as odds ratio (OR) and relative ratio (RR) with 95% confidence intervals (CI) for dichotomous outcomes. Efficacy and satisfaction outcomes were assessed using quantitative methods. Our investigations showed that combined CO2 laser and topical treatments significantly increased efficacy 5.38-fold when compared with topical agents alone (OR 5.38; 95% CI; 3.20-9.04; p < 0.00001), with low heterogeneity observed among studies (I2 = 38%). Mycological clearance comparison rates were also improved by combined treatments. The higher satisfaction of the combined group was assessed by pooled effect (OR 4.56; 95% CI; 2.78-7.49; p < 0.00001). Our evidence suggests combined therapy may exert positive effects and satisfactory safety for patients with moderate to severe onychomycosis, however, optimal combination options and appropriate dosages require more comprehensive RCTs.

Abstract
BACKGROUND Onychomycosis is the most common nail disease seen in clinical practice. Inclusion of diverse groups in onychomycosis clinical trials subjects is necessary to generalise efficacy data. OBJECTIVES We aimed to systematically review race and ethnicity reporting and representation, as well as, treatment outcomes in onychomycosis clinical trials. METHODS A PubMed search for onychomycosis clinical trials was performed in August 2020. Primary clinical trial data were included and post hoc analyses were excluded. Categorical variables were compared using chi-squared and Fisher's exact tests. Statistical significance was set at p < .05. Photos in articles were categorised by Fitzpatrick skin type. RESULTS Only 32/182 (17.5%) trials reported on race and/or ethnicity and only one trial compared treatment efficacy in different subgroups. Darker skin colours were infrequently depicted in articles. Topical treatment, location with ≥1 US-based site, industry funding type and publication date after 2000 were significantly associated with reporting of racial/ethnic data (p < .05 for all comparisons). LIMITATIONS Demographics on excluded subjects and methods of recruitment were not available. Assigning Fitzpatrick skin type is inherently subjective. CONCLUSIONS This study highlights a need for consistent reporting of races and ethnicities of onychomycosis clinical trial participants with subgroup analyses of treatment efficacies.

Abstract
Background: Onychomycosis is a common fungal infection of the nail. Objective: The study aimed to provide an update on the evaluation, diagnosis, and treatment of onychomycosis. Methods: A PubMed search was completed in Clinical Queries using the key term “onychomycosis”. The search was conducted in May 2019. The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews published within the past 20 years. The search was restricted to English literature. Patents were searched using the key term “onychomycosis” in www.freepatentsonline.com. Results: Onychomycosis is a fungal infection of the nail unit. Approximately 90% of toenail and 75% of fingernail onychomycosis are caused by dermatophytes, notably Trichophyton mentagrophytes and Trichophyton rubrum. Clinical manifestations include discoloration of the nail, subungual hyperkeratosis, onycholysis, and onychauxis. The diagnosis can be confirmed by direct microscopic examination with a potassium hydroxide wet-mount preparation, histopathologic examination of the trimmed affected nail plate with a periodic-acid-Schiff stain, fungal culture, or polymerase chain reaction assays. Laboratory confirmation of onychomycosis before beginning a treatment regimen should be considered. Currently, oral terbinafine is the treatment of choice, followed by oral itraconazole. In general, topical monotherapy can be considered for mild to moderate onychomycosis and is a therapeutic option when oral antifungal agents are contraindicated or cannot be tolerated. Recent patents related to the management of onychomycosis are also discussed. Conclusion: Oral antifungal therapies are effective, but significant adverse effects limit their use.Although topical antifungal therapies have minimal adverse events, they are less effective than oral antifungal therapies, due to poor nail penetration. Therefore, there is a need for exploring more effective and/or alternative treatment modalities for the treatment of onychomycosis which are safer and more effective.

Abstract
BACKGROUND AND OBJECTIVES While optical imaging is a useful technique to quantitate morphological differences and treatment effects, comparative investigations of the various techniques are lacking. This study aimed at evaluating intermethod agreement, reliability, and technical limitations of wide-field microscopy (WFM), reflectance confocal microscopy (RCM), and optical coherence tomography (OCT) for morphometry by assessing fractionally ablated nail tissue. STUDY DESIGN/MATERIALS AND METHODS Fifty healthy nail clippings were processed with a fractionated CO2 -laser (20 mJ/microbeam, density 15%), measured with calipers, and imaged using WFM, OCT, and RCM. Images were assessed for nail plate thickness, micropore dimensions, degree of poration, and artifacts. Repeated measurements (2-5) were taken to evaluate method repeatability using Cronbach's α and coefficients of variation (CoV), and estimate the intermethod correlation through linear correlation assessment (Pearson correlation coefficient [PCC]), ranked correlation (Kendall's tau; tau-c), and intraclass correlation (Shrout-Fleiss reliability coefficient; ICC). RESULTS The repeatability varied substantially between methods and target measurements. The level of intermethod agreement for thickness measurements performed with calipers, WFM, and OCT was high (tau-c ≥ 0.7; ICC ≥ 0.8; PCC ≥ 0.9). RCM could only image 28 out of 50 samples due to its limited penetration depth. OCT demonstrated the highest repeatability of all imaging techniques (CoV 4-7%) and nail thickness showed the highest measurement reliability (α = 0.92). Micropore dimensions correlated strongest between OCT and RCM (tau-c/ICC/PCC ≥ 0.5). All modalities were prone to artifacts, which may have adversely affected measurement variation and intermethod agreement. CONCLUSION Intermethod agreement and reliability appear to be highly dependent on the specific modality and target measurement. To reap the benefits of each technique while mitigating their limitations, an integrated approach to optical imaging is recommended. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

Abstract
Naftifine is used to treat fungal skin infections as it inhibits dermatophytes, which are the cause of onychomycosis. However, naftifine's ability to permeate the human nail barrier has not been investigated, thus, the antimycotic potential is not clearly established. This work aims to evaluate the effect of penetration enhancing factors on the accumulation of naftifine hydrochloride through human nail clippings. Naftifine polymeric nail lacquers with Eudragit RL100 were developed as a suitable delivery system. Low penetration of naftifine into nail has been determined as less than 10% of applied drug dose accumulated in the nail layers. Incorporation of thioglycolic acid into formulations resulted in increased accumulation of antifungal agent in the nail layers by 100% compared with a control group. Salicylic acid did not effect naftifine accumulation in the human nail. The permeation of naftifine through the nail increased by threefold when the thioglycolic acid-containing formulation was applied and the nail was pretreated with a fractional CO2 laser. Structural changes of the nail barrier, induced by fractional CO2 laser, were visualized by microscopy. The results suggest, that naftifine nail penetration could be significantly increased when physical and chemical enhancing factors are applied.

Abstract
Background: Device-based therapies have been used for onychomycosis patients with intolerance to systemic treatments. Photodynamic therapy (PDT) improves onychomycosis, while fractional carbon dioxide (FrCO2) augments the topical drug delivery. Comparative studies between PDT alone and laser-assisted one are lacking.Objective: We aimed to evaluate the efficacy of PDT alone versus FrCO2-assisted PDT for treatment of onychomycosis.Methods: Twenty-one patients with bilateral onychomycosis of toenails with nearly the same degree of affection were enrolled in this prospective intra-patient-controlled study. The right affected toenail was treated via PDT alone. The left toenail was treated via a FrCO2 followed immediately by PDT. The sessions were bimonthly for a total of six sessions. Direct microscopy, fungal cultures, clinical evaluation, onychomycosis severity index scoring, and patient's satisfaction were assessed before and 12 weeks after the last session.Results: Both treatments reduced significantly the onychomycosis severity index (p < .05) without significant difference between them. The improvement in nail appearance and patient's satisfaction were higher in laser-assisted PDT than PDT alone (p < .05).Conclusion: Both treatments effectively reduced the severity of onychomycosis with a high degree of safety and tolerability. Fractional CO2-assisted PDT enhanced the clinical outcome via improving the nail appearance and patient's satisfaction.Key messagePhotodynamic therapy has a good success rate in clearing onychomycosis. Addition of fractional CO2 to photodynamic therapy improves the nail appearance and induces better satisfaction to treatment.

Abstract
Onychomycosis is a fungal infection of the nail. The aim of this randomized controlled clinical trial was to compare the efficacy of 2940-nm Er:YAG laser treatment combined with a 5% amorolfine lacquer versus amorolfine monotherapy for treating onychomycosis. In this study, patients with onychomycosis of the great toenail were randomly assigned to a combination therapy group and a monotherapy group. In the combination therapy group, the included toenails were treated with a fractional 2940-nm Er:YAG laser at weeks 1, 2, 3, 4, 8, and 12, combined with a 5% amorolfine lacquer twice a week for 12 weeks, while in the monotherapy group, the included toenails were treated with only a 5% amorolfine lacquer twice a week for 12 weeks. The onychomycosis severity index (OSI) score and the mycological clearance rate (MCR) of the included toenails were assessed at baseline, week 12, and week 24. At weeks 12 and 24, the great toenails with mild and moderate onychomycosis in the combination therapy group showed obvious improvement and a greater decrease in OSI than those in the monotherapy group. At week 24, the toenails with mild and moderate onychomycosis in the combination therapy group also showed a better MCR. For the toenails with severe onychomycosis, little improvement was observed in either group at week 12 or week 24. In conclusion, fractional 2940-nm Er:YAG laser treatment combined with a 5% amorolfine lacquer is more effective than amorolfine monotherapy in short-term improvement of onychomycosis.

Abstract
Purpose To examine the benefits of different numbers of 1064-nm Nd-YAG laser treatments in patients with onychomycosis. Methods This was a pilot study of patients with onychomycosis who were divided into three groups: four treatment sessions (group A), eight sessions (group B), and 12 sessions (group C). Only infected nails of degrees II–III (Scoring Clinical Index for Onychomycosis) were included. Treatment was given once a week using a long-pulse Nd-YAG 1064-nm laser. Patients were followed at 8, 16, and 24 weeks after the first treatment. Side effects were recorded. Results Treatments were completed for 442 nails in 102 patients. The efficacy rates at 8, 16, and 24 weeks were 35.5%, 38.7%, and 37.4% for group A; 31.4%, 41.7%, and 44.0% for group B; and 27.7%, 50.0%, and 55.4% for group C, respectively. There was a significant difference in the efficacy rate at 24 weeks (P = 0.016) between groups A and C, but not for groups A vs. B, or for groups B vs. C. No difference in the efficacy rate at 8 or 16 weeks was observed among the three groups. In all three groups, the efficacy was better for degree II nails than for degree III nails (all P = 0.016) between groups A and C, but not for groups A vs. B, or for groups B vs. C. No difference in the efficacy rate at 8 or 16 weeks was observed among the three groups. In all three groups, the efficacy was better for degree II nails than for degree III nails (all Conclusions The 1064-nm Nd-YAG laser had clinical benefits against onychomycosis. Higher numbers of treatments provided better long-term (24-week) benefits, but had no impact on the short-term outcomes. The efficacy of laser treatment on degree II onychomycosis was better than for degree III.

Abstract
BACKGROUND Onychomycosis refers to fungal infections of the nail apparatus that may cause pain, discomfort, and disfigurement. This is an update of a Cochrane Review published in 2007; a substantial amount of new research warrants a review exclusively on toenails. OBJECTIVES To assess the clinical and mycological effects of topical drugs and device-based therapies for toenail onychomycosis. SEARCH METHODS We searched the following databases up to May 2019: the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase and LILACS. We also searched five trials registers, and checked the reference lists of included and excluded studies for further references to relevant randomised controlled trials. SELECTION CRITERIA Randomised controlled trials of topical and device-based therapies for onychomycosis in participants with toenail onychomycosis, confirmed by positive cultures, direct microscopy, or histological nail examination. Eligible comparators were placebo, vehicle, no treatment, or an active topical or device-based treatment. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Primary outcomes were complete cure rate (normal-looking nail plus fungus elimination, determined with laboratory methods) and number of participants reporting treatment-related adverse events. MAIN RESULTS We included 56 studies (12,501 participants, average age: 27 to 68 years), with mainly mild-to-moderate onychomycosis without matrix involvement (where reported). Participants had more than one toenail affected. Most studies lasted 48 to 52 weeks; 23% reported disease duration (variable). Thirty-five studies specifically examined dermatophyte-caused onychomycosis. Forty-three studies were carried out in outpatient settings. Most studies assessed topical treatments, 9% devices, and 11% both. We rated three studies at low risk of bias across all domains. The most common high-risk domain was performance bias. We present results for key comparisons, where treatment duration was 36 or 48 weeks, and clinical outcomes were measured at 40 to 52 weeks. Based on two studies (460 participants), compared with vehicle, ciclopirox 8% lacquer may be more effective in achieving complete cure (risk ratio (RR) 9.29, 95% confidence interval (CI) 1.72 to 50.14; low-quality evidence) and is probably more effective in achieving mycological cure (RR 3.15, 95% CI 1.93 to 5.12; moderate-quality evidence). Ciclopirox lacquer may lead to increased adverse events, commonly application reactions, rashes, and nail alteration (e.g. colour, shape). However, the 95% CI indicates that ciclopirox lacquer may actually make little or no difference (RR 1.61, 95% CI 0.89 to 2.92; low-quality evidence). Efinaconazole 10% solution is more effective than vehicle in achieving complete cure (RR 3.54, 95% CI 2.24 to 5.60; 3 studies, 1716 participants) and clinical cure (RR 3.07, 95% CI 2.08 to 4.53; 2 studies, 1655 participants) (both high-quality evidence) and is probably more effective in achieving mycological cure (RR 2.31, 95% CI 1.08 to 4.94; 3 studies, 1716 participants; moderate-quality evidence). Risk of adverse events (such as dermatitis and vesicles) was slightly higher with efinaconazole (RR 1.10, 95% CI 1.01 to 1.20; 3 studies, 1701 participants; high-quality evidence). No other key comparison measured clinical cure. Based on two studies, compared with vehicle, tavaborole 5% solution is probably more effective in achieving complete cure (RR 7.40, 95% CI 2.71 to 20.24; 1198 participants), but probably has a higher risk of adverse events (application site reactions were most commonly reported) (RR 3.82, 95% CI 1.65 to 8.85; 1186 participants (both moderate-quality evidence)). Tavaborole improves mycological cure (RR 3.40, 95% CI 2.34 to 4.93; 1198 participants; high-quality evidence). Moderate-quality evidence from two studies (490 participants) indicates that P-3051 (ciclopirox 8% hydrolacquer) is probably more effective than the comparators ciclopirox 8% lacquer or amorolfine 5% in achieving complete cure (RR 2.43, 95% CI 1.32 to 4.48), but there is probably little or no difference between the treatments in achieving mycological cure (RR 1.08, 95% CI 0.85 to 1.37). We found no difference in the risk of adverse events (RR 0.60, 95% CI 0.19 to 1.92; 2 studies, 487 participants; low-quality evidence). The most common events were erythema, rash, and burning. Three studies (112 participants) compared 1064-nm Nd:YAG laser to no treatment or sham treatment. We are uncertain if there is a difference in adverse events (very low-quality evidence) (two studies; 85 participants). There may be little or no difference in mycological cure at 52 weeks (RR 1.04, 95% CI 0.59 to 1.85; 2 studies, 85 participants; low-quality evidence). Complete cure was not measured. One study (293 participants) compared luliconazole 5% solution to vehicle. We are uncertain whether luliconazole leads to higher rates of complete cure (very low-quality evidence). Low-quality evidence indicates there may be little or no difference in adverse events (RR 1.02, 95% CI 0.90 to 1.16) and there may be increased mycological cure with luliconazole; however, the 95% CI indicates that luliconazole may make little or no difference to mycological cure (RR 1.39, 95% CI 0.98 to 1.97). Commonly-reported adverse events were dry skin, paronychia, eczema, and hyperkeratosis, which improved or resolved post-treatment. AUTHORS' CONCLUSIONS Assessing complete cure, high-quality evidence supports the effectiveness of efinaconazole, moderate-quality evidence supports P-3051 (ciclopirox 8% hydrolacquer) and tavaborole, and low-quality evidence supports ciclopirox 8% lacquer. We are uncertain whether luliconazole 5% solution leads to complete cure (very low-quality evidence); this outcome was not measured by the 1064-nm Nd:YAG laser comparison. Although evidence supports topical treatments, complete cure rates with topical treatments are relatively low. We are uncertain if 1064-nm Nd:YAG laser increases adverse events compared with no treatment or sham treatment (very low-quality evidence). Low-quality evidence indicates that there is no difference in adverse events between P-3051 (ciclopirox hydrolacquer), luliconazole 5% solution, and their comparators. Ciclopirox 8% lacquer may increase adverse events (low-quality evidence). High- to moderate-quality evidence suggests increased adverse events with efinaconazole 10% solution or tavaborole 5% solution. We downgraded evidence for heterogeneity, lack of blinding, and small sample sizes. There is uncertainty about the effectiveness of device-based treatments, which were under-represented; 80% of studies assessed topical treatments, but we were unable to evaluate all of the currently relevant topical treatments. Future studies of topical and device-based therapies should be blinded, with patient-centred outcomes and an adequate sample size. They should specify the causative organism and directly compare treatments.

Abstract
Onychomycosis is an important medical disorder affecting both health and quality of life of patients. This study was done to compare the efficacy of CO2 laser in combination with topical tioconazole versus CO2 laser only versus topical tioconazole alone in onychomycosis. A total of 120 patients with onychomycosis were randomly assigned to three groups. Group A patients were treated with fractional CO2 laser followed by topical tioconazole 28% for five sessions with 3 weeks interval. Group B patients were treated with only fractional CO2 laser for five sessions with 3 weeks interval. Group C patients were treated with only topical tioconazole 28% for 16 weeks. The clinical effect, KOH examination, and culture for the affected nails in the three groups were analyzed. One month after the last session, regarding clinical response, 55% showed complete clinical improvement in Group A versus 30% in Group B versus 25% in Group C with a significant difference in between. There was a significant difference between the three studied groups as regard KOH test and culture after treatment. Fractional CO2 laser combined with topical antifungal is a safe and effective treatment for onychomycosis.

Abstract
BACKGROUND Laser systems are a common treatment choice for onychomycosis. They exert their effects on inhibiting the growth of the fungus by selective photothermolysis but efficacy is dependent on the specific type of apparatus used. To systematically review the available published literature on the curative effects and safety of laser treatment for onychomycosis. METHODS Databases including PubMed, web of science, China National Knowledge Internet (CNKI), WanFang Database and VIP were searched systematically to identify relevant articles published up to July 2018. Potentially relevant articles were sourced, assessed against eligibility criteria by 2 researchers independently and data were extracted from included studies. A meta-analysis was performed using R software. RESULTS Thirty-five articles involving 1723 patients and 4278 infected nails were included. Meta-analysis of data extracted from these studies revealed that: the overall mycological cure rate was 63.0% (95%CI 0.53-0.73); the mycological cure rate associated with the 1064-nm Nd: YAG laser was 63.0% (95%CI 0.51-0.74); and that of CO2 lasers was 74.0% (95%CI 0.37-0.98). The published data indicate that laser treatment is relatively safe, but can cause tolerable pain and occasionally lead to bleeding after treatment. CONCLUSION Laser treatment of onychomycosis is effective and safe. The cumulative cure rate of laser treatment was significantly higher for CO2 lasers than other types of laser. Laser practitioners should be made aware of potential adverse effects such as pain and bleeding.

Abstract
Superficial fungal infections which effect the skin, hair, and nails, are widely observed in the world. Causative agents are Candida species, dermatophytes, and Malassezia species. In recent years, new antifungal agents and formulations have been developed for these infections. In addition, laser therapies have been tried for onychomycosis. There are also studies on the antifungal activity of some herbs and propolis. In the present study, relatively new treatment methods of superficial fungal infections will be described.
