Recent advances in technology have provided laser surgeons with new options for cutaneous laser resurfacing. Despite its popularity, there is limited information on the short-term and long-term side effects and complications of variable-pulsed erbium:yttrium-aluminum-garnet (erbium:YAG) laser skin resurfacing. The purpose of this study was to prospectively evaluate postoperative wound healing, ...

BACKGROUND Liposome used in spray form to encapsulate and deliver 5-aminolevulinic acid (5-ALA) into the pilosebaceous unit lowers the concentration of 5-ALA to 0.5% in photodynamic therapy (PDT) for acne, with low post-treatment photosensitivity. OBJECTIVE To investigate the clinical outcome and side effects of PDT using intense pulsed light (IPL) and 0.5% 5-ALA spray for inflammatory facial...

BACKGROUND Cutaneous aging is manifested by rhytides, dyschromias, and skin laxity. Ablative laser skin resurfacing can effectively improve many signs of skin aging; however, the photoaged patient with facial laxity often requires a surgical lifting procedure in order to obtain optimal results. Concerns with delayed or impaired wound healing has led to reluctance to perform both procedures simu...

BACKGROUND Port-wine stains (PWS) affect 0.3% to 0.5% of newborns and pulsed dye laser (PDL) remains the treatment of choice. Optimal treatment intervals have not been established. OBJECTIVE We sought to validate the optimal treatment intervals for the management of facial PWS with PDL. METHODS In all, 24 infants with facial PWS who received at least 5 treatments with the PDL at 2-, 3-, and...

The characteristic clinical features of FXS include moderate to severe mental retardation, dysmorphic facial features, joint laxity, postpubertal macro-orchidism and behavioral anomalies. Seizures are reported to occur in 10 to 20 percent of cases with a full mutation FXS and are typically of the complex partial type. Previous studies have identified marked similarities between seizures occurri...

Gingival hyperpigmentation is mostly caused by the physiologic deposition of melanin by melanocytes. Melanin pigmentation of the gingiva is completely benign and does not present a medical problem. In "Gummy Smile" Patients, melanin gingival hyperpigmentation causes an esthetic problem and physiologic disturbances. Many methods are now available for depigmentation of the gingival. This paper re...

conclusions all plants could inhibit mushroom tyrosinase, but more investigations on human tyrosinase and clinical studies are needed. results the hydroalcoholic extract of p. alkekengi showed the most tyrosinase inhibitory effect with ic50 of 0.09 mg/ml vs. 0.38, 0.38 and 2.82 mg/ml of b. persicum, a. rosea and m. vulgare, respectively. m. vulgare exhibited uncompetitive inhibition and other p...
