[Efficacy and safety of 308 nm excimer laser for vitiligo].

Objective: To assess the efficacy and safety of the 308 nm excimer laser for the treatment of vitiligo.

Methods: We treated 170 patients with stable vitiligo by using the 308 nm excimer laser. The lesions of vitiligo were treated one to two times per week for 10-30 times.

Analysis of 602 Chinese cases of nevus of Ota and the treatment results treated by Q-switched alexandrite laser.

Background: Nevus of Ota is a congenital or acquired pigmentary disorder of the skin and mucous membranes, which are areas innervated by the first and second branches of the trigeminal nerve. Nevus of Ota is very common in Asia. Nevus of Ota was effectively treated with Q-switched alexandrite (755 nm) laser, but no detailed report existed on many Chinese cases treated with Q-switched alexandrite laser.

[Effectiveness and safety of long-pulsed Alexandrite laser for hair removal in 1702 patients].

Objective: To evaluate the effectiveness and safety of long-pulsed Alexandrite laser for hair removal.

Methods: Hair removal was performed in 1702 hirsute patients with long-pulsed Alexandrite laser. Among them 1603 patients received two or more operations.

[Flashlamp-pumped pulsed dye laser (585 nm) in the treatment of port-wine stains--a retrospective study of 2317 Chinese patients].

Objective: To evaluate the efficacy and safety of 585 nm flashlamp-pumped pulsed dye lasers (PDL) in the treatment of port-wine stains (PWS).

Methods: A retrospective review was performed in 2 317 patients with PWS who visited the Dermatology Laser Centre of PUMC Hospital and accepted treatment with 585 nm PDL. The correlation between the treatment efficacy and the treatment sessions, lesion types, and usage of other therapies were analyzed.

[Clinical efficacy of Q-switched Alexandrite laser for pigmentary skin diseases in 4656 patients].

Objective: To evaluate the clinical efficacy and safety of Q-switched Alexandrite laser in the treatment of pigmentary skin, diseases ( PSDs).

Methods: Totally 4 656 patients with PSDs were treated with Q-switched Alexandrite laser. These PDSs included nevus of Ota, seborrheic keratosis, tattoo, naevus fusco-caeruleus zygomaticus, cafe-au-lait-spots, lentigo, naevus of Ito, and spilus naevus.

[Analysis of 602 cases of nevus of Ota and study of ultrastructures on the melanocytes].

Objective: To analyze clinical information and efficacy of 602 cases of nevus of Ota, and investigate the histopathology and ultrastructure on the melanocytes before and after Q-switched Alexandrite laser irradiation.

Methods: Clinical information of 602 cases of nevus of Ota were collected by applying clinical records, checking photos, and inquiry to patients by letters and telephones. Ten cases of biopsies were observed by light microscopy and 6 cases by electron microscopy before and after laser irradiation.
