[Treatment of trichiasis with a diode laser].

Background: Various methods have been used in the treatment of trichiasis: epilation, excision, cryosurgery, thermocaustic needle, and argon laser. None of these is satisfactory. Based on the principle of selective photothermolysis for destroying specifically the hair follicle, we used a diode laser and evaluated its efficacy.

[Effect of pulsed dye laser radiation on the capillary vessels of the skin].

Up to now microvaporization has been considered the basic mechanism of vascular damage induced by pulsed dye laser. Regarding the laser-tissue interaction, we present experimental results giving evidence of the significance of sound waves. Thus the transformation of photoacoustic energy is proved, facilitating the explanation of experimental and therapeutic effects.

Novel concept for a mucosal adhesive ointment.

Conventional adhesive ointments cause irritation to the mucous membranes. Therefore, a novel mucosal adhesive ointment based partly on neutralized polymethacrylic acid methyl ester was formulated. The flow curves of the ointment vehicle showed pseudoplastic properties.

[New approach in the laser therapy of nevus flammeus].

The technical properties of the flashlamp-pumped dye laser are compared with those of other lasers already used in the therapy of port-wine stains. The advantages of the dye laser seem to be evident. The main reasons are the possibility of free choice of the wavelength and the small width of beam pulse.
