Abstract

Insights

Topical antibiotic drops, particularly ofloxacin, may increase the incidence of otomycosis (fungal ear infection) in children with persistent otorrhea. Early suspicion and appropriate antifungal treatment are crucial for resolution.

Area of Science:

  • Otolaryngology
  • Pediatric Medicine
  • Infectious Diseases

Background:

  • Otomycosis, a fungal ear infection, was rarely diagnosed as a cause of persistent otorrhea before 1999.
  • An increasing incidence of otomycosis has been observed in pediatric otolaryngology outpatient settings.

Purpose of the Study:

  • To assess the contribution of ototopical antibiotic drops to the development of otomycosis in pediatric patients.

Main Methods:

  • A retrospective chart review was conducted for patients diagnosed with otomycosis between June 1999 and September 2001.
  • Twenty-six pediatric patients (17 months–29 years) diagnosed with otomycosis after treatment with topical ofloxacin for presumed bacterial otorrhea were analyzed.

Main Results:

  • All 26 patients had used ototopical antibiotics, with ofloxacin used in every case for presumed bacterial otorrhea.
  • Diagnosis of otomycosis was based on clinical and microbiological findings.
  • Antifungal therapy was successful in all 26 cases, resolving the otorrhea.

Conclusions:

  • Physicians should maintain a high suspicion for otomycosis in cases of persistent otorrhea, especially after topical antibiotic treatment.
  • While ofloxacin is effective for bacterial otorrhea, its use appears to increase the incidence of otomycosis.
  • Careful post-treatment follow-up is warranted with the use of topical antibiotic drops.

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...
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...
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...

Microbiome of the Eye

The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
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,...
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...
