[Management of onychomycosis]

Area of Science:

• Dermatology
• Mycology
• Infectious Diseases

Context:

• Onychomycosis represents 50% of all nail diseases.
• Accurate diagnosis is paramount before initiating antifungal therapy.
• Nail sample quality is critical for mycological analysis.

Purpose:

• To emphasize the importance of diagnostic confirmation in onychomycosis.
• To guide clinicians on appropriate diagnostic sampling and interpretation.
• To identify clinical factors associated with treatment failure.

Summary:

• Prescribe antifungals only after confirming onychomycosis through mycological analysis.
• Re-sampling is advised for highly suggestive clinical presentations with negative initial results.
• Eradicate infected keratin and consider alternative diagnoses if clinical features suggest treatment failure.

Impact:

• Improves diagnostic accuracy for onychomycosis.
• Reduces inappropriate antifungal prescriptions.
• Enhances treatment outcomes by identifying high-risk cases and guiding management.
