AI Article Synopsis
- Oral antifungals are the main treatment for onychomycosis, with topical treatments for mild cases, and CO laser therapy has been introduced to improve topical effectiveness.
- This study compared the effectiveness of two CO laser treatments (fractional and fully ablative) in patients with a specific type of toenail fungal infection.
- Results showed that fully ablative CO laser treatment had a higher success rate and lower relapse rate compared to fractional treatment, indicating it may be a better option for cases resistant to topical therapies.
Article Abstract
Introduction: Oral antifungals are the treatment choice for onychomycosis, and topical therapies are favored in cases of limited nail involvement. Recently, carbon dioxide (CO) laser treatment has emerged as an option to enhance the effectiveness of topical therapies.
Objectives: Our objective was to compare the efficacy of fractional ablative and fully ablative CO laser treatments for distolateral subungual onychomycosis affecting a single toenail and caused by dermatophytes.
Methods: The records of 10 patients treated with a single fully ablative CO session were matched with those of 10 patients who underwent a single CO fractional treatment. All had previously failed topical antifungal lacquers and were discharged with the prescription of topical ciclopirox nail lacquer (8%) for 3 months.
Results: The clinical response rates were 80% for the fully ablative group and 60% for the fractional group. Additionally, the mean reduction in Onychomycosis Severity Index from baseline to 8.6±1.6 weeks after treatment completion was 6.9±5.4 in the fully ablative group and 3.6±6.6 in the fractional group. The relapse rate among responders was 12.5% in the fully ablative and 33.3% in the fractional group after a mean follow-up time of 29.4±2.3 weeks.
Conclusions: Fractional and fully ablative CO laser in combination with ciclopirox lacquer could increase the response rate in onychomycosis resistant to topical antifungals when systemic therapy is contraindicated or not yet pursued. Fully ablative mode therapy is significantly more effective than fractional (P < 0.05). Further studies are needed to identify prognostic response factors and assess the long-term effectiveness of CO laser treatment.

Neutrophil extracellular traps (NETs) promote neovascularization during the acute phase after ocular chemical injury, while the local inflammatory acidic environment delays post-injury repair. Currently, the mechanism of NETs promoting neovascularization has not been fully elucidated, and there is a lack of therapeutic strategies to effectively improve the local microenvironment for corneal repair. In this study, we validated the NETs-M2-angiogenic pathway after injury.

A systematic search was performed to identify publications comparing outcomes following image-guided thermal ablation (IGTA), stereotactic ablative radiotherapy (SABR), and sublobar resection-the main treatment options applicable to high-risk patients with stage I NSCLC. There were no publications detailing completed randomized controlled trials comparing these treatment options.

Stereotactic ablative radiotherapy (SABR) has emerged as an alternative, non-surgical treatment for high-risk patients with stage I non-small cell lung cancer (NSCLC) with increased use over time. The American Association for Thoracic Surgery (AATS) Clinical Practice Standards Committee (CPSC) assembled an expert panel and conducted a systematic review of the literature evaluating the results of SABR, which is also referred to as stereotactic body radiation therapy (SBRT) or stereotactic radiosurgery (SRS), prior to developing treatment recommendations for high-risk patients with stage I NSCLC based on expert consensus. Publications detailing the findings of 16 prospective studies of SABR and 14 retrospective studies of SABR for the management of early-stage lung cancer in 54 697 patients were identified by systematic review of the literature with further review by members of our expert panel.

Background: Isotretinoin is widely used for moderate to severe acne vulgaris. Despite its broad application, isotretinoin carries a risk of permanent scarring and keloid formation following various skin procedures. As a result, a delay of at least 6-12 months after completing or discontinuing isotretinoin treatment is commonly recommended before undergoing skin procedures.
