Background
Excimer laser therapy of vitiligo generally takes months to years to achieve excellent outcomes. Platelet‐rich plasma is an autologous preparation with a focus on various growth factors that can help with vitiligo repigmentation.
Objectives
To assess the additive effect of PRP in the therapy of vitiligo on the results of the excimer laser.
Patients and Methods
A comparative study included 52 patients (8 males and 44 females) in two groups with stable (no new lesion for 6 months), nonsegmental and symmetrical vitiligo. Group I (26 patients): The patient was treated by intradermal PRP injection and the excimer laser, while group II (26 patients) was treated with the excimer laser only. The PRP injection was repeated every 3 weeks for 4 months and excimer laser two times a week and for 16 weeks till complete response. VAS for patient's satisfaction assessment, safety assessment for complications, and follow‐up for 3 months was done. Clinical (repigmentation response) and histopathological assessment was done.
Results
There was a higher statistically significant treatment response in group I compared with group II. In addition, a statistically significant correlation between the treatment response and the lesion site in group I (P < .000). A significant difference in VAS between both groups (P < .000). Few the side effects were reported.
Conclusion
The combination of PRP and excimer laser phototherapy is an efficient vitiligo treatment as PRP increases the excimer laser impact and also improves the result.
The Major Depression Inventory (MDI) is a brief questionnaire to assess the presence of a depressive disorder. We prepared an Arabic version of the MDI and tested its reliability and concurrent and discriminant validity as a diagnostic tool of major depressive disorder. A group of 50 Egyptian outpatients with major depressive disorder (assessed clinically and with the Structured Clinical Interview for DSM-IV-TR Axis I Disorders) were compared with 50 healthy controls using the MDI-A, Beck Depression Inventory (BDI) and Spielberger State-Trait Anxiety Inventory (STAI). Cronbach α was 0.91 and intraclass correlation coefficient was 0.98 (95% CI: 0.97-0.99). Scores on the MDI-A strongly correlated with BDI scores (r = 0.81) but insignificantly correlated with STAI scores. Using the MDI scoring algorithm, the sensitivity was 88.4% and specificity 78.9%. We conclude that the MDI-A has an excellent reliability and an acceptable concurrent and discriminant validity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
