Special Issue Information

Dear Colleagues,

The Special Issue, entitled ‘Onychomycosis’, aims to present the precise definition of onychomycosis and address its management with or without the preferred treatment:

  1. Diagnostic Improvements: Recent research highlights significant advancements in diagnostic techniques for onychomycosis such as polymerase chain reaction (PCR), especially in cases where traditional methods, such as direct microscopy and culture, are negative while the clinical presentation supports onychomycosis.
  2. The gold-standard treatment for onychomycosis is systemic treatment. Emerging treatments such as topical therapies (new topical treatments) are being developed to improve drug penetration and efficacy, laser therapy and photodynamic therapy (PDT).
  3. The definition of treatment success: There must be uniformity in clinical studies regarding the definition of therapeutic success in onychomycosis. Since there is usually more than one affected nail in most cases, a single nail showing complete restoration is sufficient evidence of therapeutic success.
  4. Antifungal Resistance: The issue of antifungal resistance is becoming more prominent. There are various mechanisms by which fungi develop resistance to commonly used antifungals, and novel antifungal compounds with novel mechanisms of action to overcome resistance.
  5. Prevention and Recurrence: Relapse, reinfection and the host immune response.

To summarize: this Special Issue primarily addresses the correct laboratory diagnosis alongside a clinical picture consistent with onychomycosis, the consideration of pure or combined disorders, the adaptation of appropriate treatment even in cases of resistance, the interpretation of therapeutic success, and ultimately the prevention of recurrence or reinfection.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Fungi is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Cutaneous fungal infections predominantly caused by dermatophytes are a global concern. These infections vary widely by region, age, and body site, with recent shifts in the pathogen distribution. This study examines the distribution and trends of superficial fungal infections in a large tertiary care center in Israel from 2019 to 2022. A retrospective analysis of 2244 patients with suspected fungal infections was performed, utilizing PCR and fungal cultures for diagnosis. Confirmed fungal infections were present in 53.0% of cases. In adults, infections predominantly affected the nails and feet, while in children, the scalp and nails were the most involved sites. Trichophyton rubrum was the most common pathogen overall, but T. tonsurans was the leading cause of scalp, face, and neck infections, as well as tinea corporis in children. T. tonsurans incidence significantly increased in adults and became the most frequent agent of upper-body tinea corporis by 2022. These findings highlight a shift in pathogen distribution, with T. tonsurans emerging as the leading cause of upper-body skin infections, underscoring the need for targeted prevention strategies and further investigation of its transmission routes.
