Therapeutic Cure requires both Clinical Cure and Mycological Cure. Clinical Cure was based on the following signs and symptoms: fissuring, erythema, maceration, vesiculation, scaling, exudation, pruritus, burning. Each clinical symptom was evaluated using a 0-3 point rating scale: none=0, mild=1, moderate=2 or severe=3. If the score for erythema was ≤ 2 and the sum for all of the other 7 signs and symptoms was <2 then the patient was considered a Clinical Cure. Mycological Cure: The potassium hydroxide (KOH) and the fungal culture were both negative.
