Brief summary
There are several topical treatment for Pityriasis Versicolor including ketoconazole and selenium sulfide. Ketoconazole is a broad spectrum anti-fungal drug from imidazole group that has been reported to be effective in PV. The study aimed to reveal the mycological efficacy, safety, recurrence and cost-effectiveness of selenium sulfide 1.8% shampoo (SeS2) and ketoconazole 2% shampoo in the treatment of pityriasis versicolor. A double blind randomized controlled trial was performed in patients with PV during September-December 2018. Patients who involved in this study were allocated to SeS2 or ketoconazole 2% based on block randomization. Physical examinations, scale provocation test, Wood lamp and potassium hydroxide (KOH) examination were conducted to evaluate the treatment response and side effects on 7th - 14th day. Intention to treat analysis was performed in this study. cost-effectiveness was analyzed by Incremental Cost-Effectiveness Ratio (ICER).

Inclusion criteria
* Having PV characteristic skin lesions,proven by 20% KOH scraping test and Parker Blue-Black® ink, with the founding of short hyphae and group spores or short hyphae only * willing to participate in the study by signing the written informed consent * Subjects under the age of 18 with permission from parents or guardians.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| mycology efficacy | 7 days | skin scrapping with KOH test 20% and Parker Blue-Black® ink with the founding of short hyphae and group spores or short hypha only as a positive result |
| compliance | 7 days | the number of day in which a participant using the shampoo which was assigned for minimum 5 days or more and the remaining volume of shampoo does not exceed 25 ml. |
| side effect | 7 days | based on clinical symptoms : itching, burning or stinging sensation. Assessed based on patient records in the diary and through interviews during control |
| cost-effectiveness | two weeks | Cost calculations include administrative fees (registration and consultation of doctors), laboratory examinations, medical expenses and compensation for side effects adjusted for the duration of therapy. The results of the calculation of costs obtained are then linked to the negative outcome difference (KOH is still positive) or the value of absolute risk reduction (ARR) on day 14. So that cost efficacy is seen from Incremental Cost-Effectiveness Ratio |
| recurrence | 1 month | if the KOH test 20% give a positive result again |
