Systemic isotretinoin therapy causes significant alterations in sTFTs. Dose dependent or long-term effects of systemic isotretinoin on sTFTs needs further evaluation.

ÖzBackground and Design: Vitiligo is a chronic skin disease. To reduce side effects associated with current treatment modalities, new treatment methods are required. Microphototherapy was introduced to treat vitiligo patients with a limited number of lesions (lesions affecting <10% of the body surface area). Materials and Methods: Our study has aimed to evaluate the efficacy of microphototherapy in vitiligo patients with localized lesions. In this unblinded and prospective study, patients were treated thrice weekly for at least 50 sessions using an MedLight CupCUBE Grimed ® microphototherapy device which emits ultraviolet B spectrum with a starting dose of 150 mJ/cm 2 for 5 seconds and with increments of 30 mj/cm 2 , 1 second at each session. At the end of the 50 th session, 50% reduction in Vitiligo Area Scoring Index (VASI) score was accepted as the required minimum response. Results: Thirty-three lesions from 14 patients were treated. Treatment outcome was evaluated based on the VASI. Between 0 th and 50 th sessions, the mean VASI score in 33 lesions decreased from 2.25 to 1.79 showing 20.4% decline (p<0.05). Twenty-one of 33 lesions exhibited decrease in VASI scores at the end of the 50 th session although only 11 of these 21 lesions reached the target of VASI 50% while the remaining 10 lesions did not reach the target. As a result, 11 lesions (33.3%) reached VASI 50% while the remaining 22 lesions (66.7%) did not reach the target. Conclusion: The efficacy of the MedLight CupCUBE Grimed ® microphototherapy device was poor with these starting doses, durations and increments for the treatment of patients with vitiligo who had localized lesions. Trying topical therapies initially, calculating minimal erythema dose and, thus, measuring the beginning ultraviolet doses and durations as a way to decrease the number of in-hospital sessions are feasible rather than applying this technique as the first option or alone in vitiligo patients with non-segmental and localized lesions. Keywords: Vitiligo, phototherapy, treatment Amaç: Vitiligo kronik bir deri hastalığıdır. Mevcut tedavi yöntemlerine bağlı oluşabilen yan etkileri azaltmak için yeni tedavi yöntemlerine ihtiyaç bulunmaktadır. Mikrofototerapi yöntemi sınırlı sayıda lezyona sahip (lezyonların vücut yüzey alanının %10'undan azını etkilemesi) vitiligo hastalarını tedavi etmek için kullanılmaya başlamıştır. Gereç ve Yöntem: Çalışmamız lokalize lezyonlara sahip vitiligo hastalarında mikrofototerapinin etkinliğini değerlendirmeyi hedeflemektedir. Prospektif olan ve kör olmayan bu çalışmada hastalara ultraviyole (UV) B ışını yayan MedLight CupCUBE Grimed ® mikrofototerapi cihazı ile başlangıç UV dozu 150 mJ/cm 2 ve 5 saniye, her seansta doz artımı 30 mj/cm 2 ve 1 saniye olacak şekilde haftada 3 kez en az 50 seans boyunca tedavi uygulanmıştır.

Background/aim: Psoriasis is a chronic skin disease. To reduce side effects associated with current treatment modalities, new treatment methods are required. Some clinicians have begun to use microphototherapy to treat psoriatic patients with a limited number of lesions (lesions affecting <10% of the body surface area). Materials and methods:Microphototherapy is indicated in patients whose lesions persist despite systemic and topical treatment or when such treatment is contraindicated. Our study aimed to evaluate the efficacy of microphototherapy in psoriasis patients with localized lesions. Patients in this unblinded and prospective study were treated three times a week for 50 sessions using a MedLight CupCUBE Grimed microphototherapy device that emits an ultraviolet B (UVB) spectrum.Results: Forty-five lesions in 23 psoriatic patients were treated. Treatment outcome was evaluated based on the Psoriasis Severity Index (PSI). PSI scores decreased significantly during the treatment. Conclusion:The MedLight CupCUBE Grimed microphototherapy device was effective for the treatment of psoriasis patients with localized lesions. The device can administer UVB radiation to involved regions while protecting uninvolved regions and minimizing radiation dose. However, having to be administered by experienced technicians and the long time required for each treatment session are disadvantages of the technique.
