Tinea capitis, a common scalp infection in children, is primarily caused by Trichophyton or Microsporum species. Newer oral antifungal treatments show efficacy similar to griseofulvin but with shorter therapy durations.

Area of Science:

  • Dermatology
  • Mycology
  • Infectious Diseases

Background:

  • Tinea capitis is a prevalent fungal infection affecting children's scalps.
  • Predominant causative agents include Trichophyton and Microsporum species, with varying global epidemiology.
  • In North America, Trichophyton tonsurans is now the most common cause, shifting from historical prevalence of Microsporum species.

Purpose of the Study:

  • To review the epidemiology, clinical presentations, diagnosis, and treatment of tinea capitis.
  • To highlight the changing etiological landscape of tinea capitis, particularly in North America.
  • To discuss current and emerging therapeutic options for tinea capitis.

Main Methods:

  • Literature review of dermatophyte infections, focusing on tinea capitis.

  • Analysis of epidemiological data and etiological shifts.
  • Evaluation of diagnostic methods and treatment efficacy.
  • Main Results:

    • Tinea capitis presents with diverse clinical signs, including scaling, 'black dot' patterns, and inflammatory kerions.
    • Mycological examination is crucial for diagnosis; Wood's light is useful for some species but not T. tonsurans.
    • Asymptomatic carriers contribute to transmission, and inanimate objects can harbor spores.

    Conclusions:

    • Effective treatment of tinea capitis necessitates oral antifungal agents.
    • Newer antifungals like terbinafine, itraconazole, and fluconazole offer promising alternatives to griseofulvin, with comparable efficacy and shorter treatment courses.
    • Both older and newer antifungal medications possess favorable safety profiles, promoting patient compliance.
