Management of tinea capitis. A status report
1University of Nevada School of Medicine, Las Vegas, USA.
Abstract:
Tinea capitis is the most common pediatric fungal infection, usually affecting school-age children. It is caused by a dermatophyte from the genus Trichophyton or Microsporum. The predominant pathogens vary according to geographic location. Infection rates are higher in urban regions, especially those with overcrowded living conditions. In the United States, the incidence is highest among African-American children and appears to be significantly lower among Asian Americans. Tinea capitis may persist into adulthood, especially in females with Trichophyton tonsurans infection. Tinea capitis also has been reported in neonates, infants, and elderly patients.
Insights
Tinea capitis, a common fungal infection in children, is caused by dermatophytes like Trichophyton. Predominant species and incidence vary by geography and ethnicity, impacting school-age children most frequently.
Area of Science:
- Mycology
- Pediatric Infectious Diseases
- Dermatology
Background:
- Tinea capitis is the most prevalent fungal infection in children, primarily affecting school-aged individuals.
- Caused by dermatophytes, mainly from the genera Trichophyton and Microsporum, with geographic variations in dominant species.
- Higher infection rates are observed in urban settings and among specific ethnic groups, notably African-American children in the U.S.
Purpose of the Study:
- To summarize the epidemiology and common causative agents of Tinea capitis.
- To highlight demographic and geographic factors influencing Tinea capitis prevalence.
- To discuss the potential for persistence into adulthood and occurrence in other age groups.
Main Methods:
- Literature review of Tinea capitis epidemiology.
- Analysis of geographic and demographic data on fungal infections.
- Review of etiological agents and their prevalence.
Main Results:
- Geographic location significantly influences the predominant Tinea capitis pathogens.
- Incidence varies among ethnic groups, with higher rates in African-American children in the U.S.
- Tinea capitis can persist into adulthood, particularly in females infected with Trichophyton tonsurans.
Conclusions:
- Tinea capitis epidemiology is complex, influenced by location, ethnicity, and living conditions.
- Understanding pathogen distribution is crucial for effective diagnosis and treatment.
- The infection can affect a wide age range, from neonates to the elderly.
