Hyphal Index Following a Potassium Hydroxide Mount in Dermatophytosis.

Area of Science:

• Medical Mycology
• Dermatology
• Diagnostic Pathology

Background:

• Dermatophytes are keratinophilic fungi causing superficial infections.
• Potassium hydroxide (KOH) microscopy is a standard diagnostic method for dermatophytosis.
• Current KOH mount interpretation is qualitative, lacking objective quantification.

Purpose of the Study:

• To develop and validate a semi-quantitative method for KOH mounts in dermatophytosis.
• To introduce the Hyphal Index (HI) as a standardized measurement.
• To assess the potential of HI as a prognostic tool in clinical management.

Main Methods:

• Semi-quantification of fungal elements in KOH mounts.
• Development of the Hyphal Index (HI) based on fungal load.
• Validation of HI against clinical assessment of dermatophytosis severity.

Main Results:

• The Hyphal Index (HI) provides a semi-quantitative measure of fungal elements in KOH mounts.
• HI demonstrates potential for correlating fungal load with disease severity.
• The method offers a simple, reproducible approach to KOH mount assessment.

Conclusions:

• The Hyphal Index (HI) is a viable tool for semi-quantifying KOH microscopy in dermatophytosis.
• HI may aid in assessing disease severity and guiding treatment.
• Further validation is recommended to establish HI as a standard prognostic indicator.
