Onychomycosis laser

BACKGROUND: Onychomycosis is a fungal infection of the nail unit that affects a large patient population globally. Onychomycosis, or tinea unguium, has a benign chronic clinical course; however, it can cause complications in certain patient populations suffering from diabetes and peripheral vascular disease. As nails grow slowly, onychomycosis requires a lengthy treatment plan, and choosing appropriate treatments can be challenging. There are a variety of treatment modalities available for patients including topical, oral, laser, light therapy, procedures such as avulsion and matrixectomy, supplements, over-the-counter medication, and plasma therapy that can be used as monotherapy or in combination for patient satisfaction...

BACKGROUND AND OBJECTIVES: Onychomycosis is common and important to distinguish from other nail diseases. Rapid and accurate diagnosis is necessary for optimal patient treatment and outcome. Non-invasive diagnostic tools have increasing potential for nail diseases including onychomycosis. This study evaluated line-field confocal optical coherence tomography (LC-OCT) as a rapid non-invasive tool for diagnosing onychomycosis as compared to confocal laser scanning microscopy (CLSM), optical coherence tomography (OCT), and conventional methods...

Onychomycosis is the most common fungal nail infection accounting for 50% of nail disorders. This infection is most common in the toenails than in the nails of the fingers. It is caused by various fungal species like Trichophyton rubrum, Trichophyton mentagrophytes, Scopulariopsis brevicaulis, Aspergillus spp, Fusarium spp, Acremonium spp, Alternaria spp, and Neoscytalidium. Among them, dermatophyte fungus is involved in 70% to 80% of infections. Clinically, there are five types of onychomycosis classified based on causative organism and location of infection origin...

BACKGROUND: Onychomycosis is a fungal nail infection of difficult treatment due to the fungal survival capacity and reduced number of effective therapies. The present study aimed to isolate fungal agents that cause onychomycosis in immunocompetent patients and evaluate how LASER treatments affect the growth and ultrastructure of isolates. METHODS: In total, 21 patients with positive direct microscopic examination (DME) for onychomycosis had nail samples collected for cultivation and phenotypic identification of microorganisms...

Introduction: The fungal nail infection (onychomycosis) involves 18%-40% of all nail disorders, which, although not fatal, can cause mechanical, aesthetic, occupational, and economic problems. Drug treatments due to prolonged treatment periods, drug interactions, adverse effects, and slow progression may associate with numerous negative outcomes. This study aimed to evaluate the long-pulsed 1064-nm Nd: YAG laser effect on fungal colonies and subsequently possible change in the minimum inhibitory concentrations (MICs) of common antifungals compared with the same non-lasered colonies as a novel way to investigate laser and antifungal interaction...

Onychomycosis is a highly prevalent and persistent nail disorder primarily caused by dermatophytes. The effectiveness of current topical and systemic antifungals is limited by the extent and severity of the infection, patient demographics and health status, hepatic toxicity, drug interactions and low compliance. Laser therapy is a promising modality for safe and cost-effective removal of mycotic nail. This prospective study assessed the performance of a multi-series long-pulsed Nd:YAG 1064 nm regimen (30-40 J/cm2 , 1 Hz) in the treatment of 213 mycotic nails in 31 patients...

BACKGROUND: Onychomycosis is the most common infective nail disease, and treatment includes topical and systemic antifungal medications. Recently, laser therapy has emerged as a therapeutic option for patients who are unable to take oral antifungal agents. We investigated the effectiveness and safety of a novel long-pulsed 1,064-nm gallium arsenide (GaAs) laser surgical device for onychomycosis. METHODS: This 24-week single-center, single-blind, active-controlled exploratory clinical study comparatively evaluated the long-pulsed 1,064-nm GaAs laser (Healer1064) with the short-pulsed Nd:YAG laser surgical device in 20 participants randomly assigned to receive either test or control treatment at 4-week intervals during the 12-week treatment period...

Onychomycosis is difficult to treat due to long treatment durations, poor efficacy rates of treatments, high relapse rates, and safety issues when using systemic antifungal agents. Device-based treatments are targeted to specific regions of the nail, have favorable safely profiles, and do not interfere with systemic agents. They may be an effective alternative therapy for onychomycosis especially with increasing reports of squalene epoxidase gene mutations and potential resistance to terbinafine therapy. In this review, we discuss four devices used as antifungal treatments and three devices used as penetration enhancers for topical agents...

INTRODUCTION: Onychomycosis, a multifactorial fungal infection of the nails, shows a global prevalence of about 5.5% and is responsible for 50% of all nail infections. Symptoms range from yellowish- brown spots under the nail surface to separation of nail from the nail bed. To develop effective management strategies, it is necessary to understand the etiology, pathophysiology, barriers, and risk factors of onychomycosis. Oral route of drug delivery is one of the routes utilized to deliver anti-fungal agents like griseofulvin, ketoconazole etc...

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...

Rose bengal (RB) solutions coupled with a green laser have proven to be efficient in clearing resilient nail infections caused by Trichophyton rubrum in a human pilot study and in extensive in vitro experiments. Nonetheless, the RB solution can become diluted or dispersed over the tissue and prevented from penetrating the nail plate to reach the subungual area where fungal infection proliferates. Nanoparticles carrying RB can mitigate the problem of dilution and are reported to effectively penetrate through the nail...

This work investigates the synthesis of linalool-containing invasomes for terbinafine (TBF-IN) in order to increase the solubility, bioavailability, and nail permeability of terbinafine (TBF) for transungual administration. TBF-IN was created utilising the thin-film hydration technique, and with the Box-Behnken design (BBD), optimisation was carried out. TBF-INopt were investigated for vesicle size, zeta potential, PDI (Polydispersity index), entrapment efficiency (EE) and in vitro TBF release. In addition, nail permeation analysis, TEM (transmission electron microscopy), and CLSM (confocal scanning laser microscopy) were performed for further evaluation...

Onychomycosis is a fungal infection of the nail unit caused by various species of dermatophytes, non-dermatophytic moulds or yeasts.
