Abstract
This review focuses on nail changes that do not belong to the group of benign or malignant nail tumors. These common afflictions of the nail include structural changes in and under the nail plate as well as inflammation around and in the nail bed. They include onychomycoses, nail psoriasis, onychodystrophies, subungual hematoma, paronychia, ingrown nails and pincer nails. Due to the peculiar anatomy and physiological growth conditions of the nail, the pathology does not necessarily stem from the site of the clinical problem and calls for careful inspection and interpretation.

Methylene blue-mediated photodynamic therapy may be superior to 5% amorolfine nail lacquer for non-dermatophyte onychomycosis. PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE 2021; 37:183-191. [PMID: 33145834 DOI: 10.1111/phpp.12624] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Revised: 05/15/2020] [Accepted: 11/01/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND Methylene blue-mediated photodynamic therapy as an antimicrobial has been reported to improve onychomycosis. OBJECTIVES To compare the short-term efficacy of methylene blue-mediated photodynamic therapy (MB-PDT) and 5% amorolfine nail lacquer (AMO) for toenail onychomycosis using higher intensity and shorter total treatment period than previously reported. METHODS Twenty-seven toenails with onychomycosis were randomized to receive either six biweekly sessions of MB-PDT or AMO for twelve weeks. Dermoscopic photography was used for onychomycosis severity index assessment under a dermoscopic inspection (d-OSI) at baseline, weeks 6, 10, 14 and 22 as well as microscopic and microbiological tests. Adverse events were recorded. RESULTS All subjects completed the study. Causative organisms found were exclusively non-dermatophytes including Fusarium spp., Asperillus spp.,and yeasts. Fifteen toenails received MB-PDT, whilst 12 received AMO. D-OSI showed greater improvement in MB-PDT than in AMO groups at weeks 6, 10, 14 as well as 22, with median changes of -2, -3, -4 (P = .055). and - 3 respectively in the MB-PDT group. The AMO group displayed the median d-OSI change of 0 throughout the study period. Mycological cure rate at 22 weeks in MB-PDT and AMO group was 73.3% and 66.67% (P > .05). Clinical cure rate at 22 weeks in MB-PDT (26.7%) was higher than AMO (16.7%), (P > .05). All patients only felt comfortably warm during the MB-PDT treatment. No major adverse events were found in both groups. CONCLUSIONS MB-PDT appeared to be more efficacious for non-dermatophyte onychomycosis than AMO particularly in a limited period and moderately severe onychomycosis.

Efficacy of Two-Stage Treatment of Onychomycosis Using a Long-Pulsed Nd:YAG 1064-nm Laser. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:3647519. [PMID: 31316570 PMCID: PMC6601484 DOI: 10.1155/2019/3647519] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/18/2019] [Accepted: 06/10/2019] [Indexed: 11/17/2022]
Abstract
OBJECTIVES Onychomycosis is a fungal infection of the nail bed, nail matrix, and nail plate. Lasers have recently been studied as future clinical options for onychomycosis. We sought to evaluate the efficacy of the long-pulsed Nd:YAG 1064-nm laser on onychomycosis using a two-stage treatment. METHODS A total of 100 affected nails (88 toenails and 12 fingernails from 22 patients) were treated using a long-pulsed Nd:YAG 1064-nm laser. The self-controlled treatment schedule included the first stage (1 session per week for 8 weeks) and the second stage (1 session every 4 weeks for 16 weeks). Patients were followed up with for 12 weeks after the last laser treatment. Direct microscopy, cultures, and clinical assessments were performed at various time points. RESULTS Of the nails studied, 84% were infected by Trichophyton rubrum, while others were coinfected with T. rubrum and other fugal strains. The mycological clearance rate and the clinical efficacy rate of the nails were 29% and 21% after the first stage, 69% and 35% after the second stage, and 67% and 39% during follow-up, respectively. The second stage of laser treatment significantly improved the mycological clearance and clinical efficacy. CONCLUSION Long-pulsed Nd:YAG 1064-nm laser two-stage treatment was effective for onychomycosis, with significantly improved mycological clearance and clinical efficacy. This trial is registered with ChiCTR 1900021669.

Abstract
Onychomycosis is the most common affliction of the nail. It may be caused by dermatophytes, yeasts, and non-dermatophyte molds. Traditionally, oral antifungal treatments have been used to treat the fungus, although they can be accompanied by side effects and drug interactions. Topical treatments provide an alternative modality, bypassing the systemic effects of oral drugs; recent research has centered on topical drug improvement and development. Physical and laser treatments are being used in conjunction with topicals, which may help penetrate the thick nail plate. In this review, techniques from all categories are outlined: both novel experimental approaches and progress and effectiveness of recently developed treatments. More long-term studies are required to determine the efficacy of various treatments, but cure rates are improved when patients adhere to treatments and follow preventative measures to avoid disease recurrence.

Abstract
Treatment of superficial fungal infections has come a long way. This has, in part, been through the development and evaluation of new drugs. However, utilising new strategies, such as identifying variation between different species in responsiveness, e.g., in tinea capitis, as well as seeking better ways of ensuring adequate concentrations of drug in the skin or nail, and combining different treatment methods, have played equally important roles in ensuring steady improvements in the results of treatment. Yet there are still areas where we look for improvement, such as better remission and cure rates in fungal nail disease, and the development of effective community treatment programmes to address endemic scalp ringworm.

Abstract
BACKGROUND Nail disorders can arise at any age. About half of all nail disorders are of infectious origin, 15% are due to inflammatory or metabolic conditions, and 5% are due to malignancies and pigment disturbances. The differential diagnosis of nail disorders is often an area of uncertainty. METHODS This review is based on publications and guidelines retrieved by a selective search in PubMed, including Cochrane reviews, meta-analyses, and AWMF guidelines. RESULTS Nail disorders are a common reason for derma - tologic consultation. They are assessed by clinical inspection, dermatoscopy, diagnostic imaging, microbiological (including mycological) testing, and histopathological examination. Some 10% of the overall population suffers from onychomycosis, with a point prevalence of around 15%. Bacterial infections of the nails are rarer than fungal colonization. High-risk groups for nail disorders include diabetics, dialysis patients, transplant recipients, and cancer patients. Malignant tumors of the nails are often not correctly diagnosed at first. For subungual melanoma, the mean time from the initial symptom to the correct diagnosis is approximately 2 years; this delay is partly responsible for the low 10-year survival rate of only 43%. CONCLUSION Evaluation of the nail organ is an important diagnostic instrument. Aside from onychomycosis, which is a common nail disorder, important differential diagnoses such as malignant diseases, drug side effects, and bacterial infections must be considered.

Abstract
Background Onychomycosis is one of the most prevalent fungal diseases in the general population. However, treatment is of limited effectiveness and must be administered for long periods of time. Systemic antifungal agents are associated with adverse effects. Objective We evaluated the clinical efficacy and safety of a 1,064-nm neodymium-doped yttrium aluminium garnet (Nd:YAG) laser with amorolfine nail lacquer to treat onychomycosis. Methods The 128 patients were randomly divided to 2 groups: 64 in the experimental group were treated with 1,064-nm Nd:YAG laser therapy and amorolfine nail lacquer; the other 64 were in a control group treated with topical amorolfine lacquer monotherapy. The laser treatment was 4 sessions at 4-week intervals and amorolfine lacquer was applied once a week for 16 weeks. Efficacy was assessed as response rate from standardized photographs with ImagePro®Plus (Media Cybernetics, Inc., USA) analysis, microscopic examination, and subjective evaluation. Results At 16 weeks, the experimental group showed a significantly higher cumulative cure rate than the control group (71.88% vs. 20.31%, p<0.0001). Clinical therapeutic effects were linked to patient satisfaction. The percent of “very satisfied” or “satisfied” responses was higher in the test group than the control group (81.25% vs. 23.44%). The treatment regimen was well tolerated, with transient discomfort observed in the test group. Conclusion The 1,064-nm Nd:YAG laser with amorolfine nail lacquer was effective and safe for treating onychomycosis. This therapy should be considered an alternative treatment, especially for patients with contraindications to systemic antifungal agents.

Abstract
Background: Onychomycosis is a fungal infection of the nail plate and subungual area. In this study, we examined the efficacy of laser treatment using self-controlled study programs involving a long-pulsed Nd:YAG 1064-nm laser combined with oral medication. Methods: Self-controlled strategies were followed in this study. The patients received treatment with oral itraconazole in conjunction with long-pulsed Nd:YAG 1064-nm laser treatment at the nails of the unilateral limb once a week for a total of four times. A total of 84 affected nails were divided into Group A (mild to moderate) and Group B (severe) according to disease severity. Affected nails with the same Scoring Clinical Index for Onychomycosis scores were selected to compare the therapeutic effects of the pure medication treatment group and the combination treatment group with a 24-week follow-up period. Results: In Group A, at the 8th, 16th, and 24th weeks of follow-up, the efficacies in the pure medication treatment group were 81.0%, 81.0%, and 90.5%, respectively, while those in the combination treatment group were 100%, 95.2%, and 90.5%, respectively. The differences between groups were not significant (8th week: χ2 = 4.421, P > 0.05; 16th week: χ2 = 2.043, P > 0.05; 24th week: χ2 = 0.00, P > 0.05). In Group B, at the 8th, 16th, and 24th weeks of follow-up, the efficacies in the pure medication treatment group were 61.9%, 66.7%, and 52.4%, respectively, while those in the combination treatment group were 95.2%, 90.5%, and 100%, respectively. The differences between groups at the 8th and 24th weeks of follow-up were statistically significant (8th week: χ2 = 6.929, P < 0.05; 24th week: χ2 = 13.125, P < 0.05). Conclusions: For patients with mild or moderate onychomycosis, we recommended a pure medication treatment or combination treatment with medication and laser. For those patients with severe onychomycosis, we recommended a combination of medication and laser therapy.

Abstract
Skin mycoses are caused mainly by dermatophytes, which are fungal species that primarily infect areas rich in keratin such as hair, nails, and skin. Significantly, there are increasing rates of antimicrobial resistance among dermatophytes, especially for Trichophyton rubrum, the most frequent etiologic agent worldwide. Hence, investigators have been developing new therapeutic approaches, including photodynamic treatment. Photodynamic therapy (PDT) utilizes a photosensitive substance activated by a light source of a specific wavelength. The photoactivation induces cascades of photochemicals and photobiological events that cause irreversible changes in the exposed cells. Although photodynamic approaches are well established experimentally for the treatment of certain cutaneous infections, there is limited information about its mechanism of action for specific pathogens as well as the risks to healthy tissues. In this work, we have conducted a comprehensive review of the current knowledge of PDT as it specifically applies to fungal diseases. The data to date suggests that photodynamic treatment approaches hold great promise for combating certain fungal pathogens, particularly dermatophytes.
