Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
Antifungal Agents01:15

Antifungal Agents

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

Summary

Tinea incognito (TI) in children has increased, with most cases occurring in those over 9 years old. This study highlights key differences in childhood TI compared to other tineas.

Area of Science:

  • Dermatology
  • Pediatric Infectious Diseases
  • Medical Mycology

Background:

  • Tinea incognito (TI) incidence is rising, particularly in pediatric populations.
  • Limited large-scale case series exist for childhood TI.
  • Understanding TI's characteristics in children is crucial for diagnosis and management.

Purpose of the Study:

  • To analyze the epidemiological, clinical, and microbiological features of childhood tinea incognito.
  • To compare these characteristics with other tineas diagnosed in children.
  • To report the largest case series of childhood TI to date.

Main Methods:

  • Retrospective study of 818 tinea cases in children (1977-2006).
  • Focused analysis on 54 diagnosed cases of tinea incognito.

  • Comparison of TI cases with other tinea diagnoses within the same period.

    • Main Results:

    • Tinea incognito (TI) diagnosis in children increased significantly in the last 15 years of the study period.
    • Most affected children were over 9 years old, with tinea corporis and tinea faciei being the most common clinical forms.
    • Topical steroids were used in 68.5% of TI cases; Trichophyton mentagrophytes was the most frequent isolate.

    Conclusions:

    • Childhood tinea incognito (TI) incidence has demonstrably increased.
    • Significant epidemiological and clinical differences exist between TI and other tineas in children.
    • The findings underscore the importance of considering TI in pediatric dermatology, especially with prior topical steroid use.
