Repigmentation of vitiliginous facial area after Q-switched Nd-YAG laser therapy for depigmentation: Is it a case of true reverse Koebner phenomenon in vitiligo?
The patients with universal vitiligo and residual pigmented patches usually do not benefit from available repigmenting methods and are better scheduled for depigmentation by medical, laser,and or freezing procedures. A 37-year-old lady with universal vitiligo and remaining pigmentation in the left anterior chest wall, ...
متن کاملبررسی و مقایسه اثر q-switched nd yag laser و erbium laser در درمان ضایعات پیگمانته
هدف: این مطالعه به منظور بررسی و مقایسه اثر q-switched nd yag laser و erbium laser در درمان ضایعات پیگمانته انجام شده است. روش مطالعه: 116 فرد مبتلا به ضایعات پیگمانته از نوع فرکل و خال وارد مطالعه شدند که 58 مورد با استفاده از q-switched nd yag laser و 58 مورد با لیزر erbium درمان شدند و در نهایت میزان اثربخشی (از بین رفتن کامل ضایعات) در دو گروه تعیین و مقایسه گردید. یافته ها: در این مطالعه...
15 صفحه اولEfficient Selection of High-Order Laguerre–Gaussian Modes in a Q-Switched Nd : YAG Laser
Intra-cavity binary phase elements are incorporated into a -switched Nd : YAG laser resonator to obtain efficient high-order transverse mode selection. The resonator configuration is analyzed using the propagation-matrix diagonalization method and the Fox–Li algorithm, and a simple model for predicting the relative output powers of the selected modes is developed. The predicted results are veri...
متن کاملQ - switched Cryogenically Cooled Yb : YAG Laser
This work describes a cryogenic, electro-optically -switched Yb:YAG laser that generates 114-W average TEM power with 47% optical-to-optical efficiency. Pulse repetition frequency is 5 kHz, pulse duration is 16 ns full-width at half-maximum, and is less than 1.05.
متن کاملCryotherapy is more effective and faster than Q-switched Nd-YAG laser fordepigmentation in universal vitiligo patients
Background: Although cryotherapy has been reported as atechnique for depigmenting residual pigmented patches inpatients with universal vitiligo, Q-switched Nd-YAG lasershave not yet been used for this purpose. The aim of this studywas to compare the efficacy of cryotherapy with that of 532nmQ-switched Nd-YAG laser therapy for depigmentation in patientswith universal vitiligo.Method: Six adult p...
