Question 1

What are the advantages of laser treatment for onychomycosis?

Accepted Answer

Non-invasive, no systemic drug side effects, and effective at killing fungi in the nail plate and bed

Answer

Laser therapy uses focused light energy to heat and destroy fungal organisms within the nail without systemic side effects. However, multiple sessions may be needed, insurance rarely covers it, and long-term efficacy data varies.

Question 2

What is the role of urea cream in nail treatment?

Accepted Answer

High-concentration urea (40-50%) softens and dissolves thickened nail tissue, facilitating debridement and improving topical antifungal penetration

Answer

Urea at high concentrations (40-50%) is a keratolytic agent that softens and breaks down thickened nail protein, making mechanical debridement easier and allowing topical antifungal medications to penetrate deeper.

Question 3

What are the contraindications for nail procedures in patients on anticoagulant therapy?

Accepted Answer

Increased bleeding risk requires extra caution, gentler techniques, and possibly physician consultation before invasive procedures

Answer

Patients on blood thinners (warfarin, heparin, DOACs) bleed more easily and may develop hematomas from minor trauma. Extra care must be taken to avoid cutting skin, and the physician should be consulted for invasive procedures.

Question 4

What is photodynamic therapy (PDT) for nail fungus?

Accepted Answer

A treatment using photosensitizing agents and specific wavelengths of light to kill fungal organisms in the nail

Answer

PDT involves applying a photosensitizing agent to the nail, which is absorbed by fungal cells, then exposing it to specific light wavelengths that activate the agent, generating reactive oxygen species that destroy the fungi.

Question 5

What patient education should accompany nail fungus treatment?

Accepted Answer

Importance of completing full treatment course, keeping nails clean and dry, wearing breathable footwear, and treating contaminated shoes

Answer

Patient education should cover treatment compliance, foot hygiene, wearing moisture-wicking socks, alternating shoes, using antifungal shoe spray, avoiding barefoot walking in public areas, and understanding recurrence risk.
