The Surgical Anatomy and the Deep Plane Thread Lift of the Buccal Fat Pad.

Background: Management of facial rejuvenation by the thread lift procedure has evolved over the past few years. The role of deep plane thread lift for buccal fat pad reposition was advocated. However, there are concerns about the risks and the feasibility of the deep plane thread lift.

Minimally invasive approaches to axillary osmidrosis treatment: A comparison between superficial liposuction with automatic shaver curettage, subcutaneous laser treatment, and microwave-based therapy with a modified technique.

Background: Minimally invasive techniques, including superficial liposuction with automatic shaver curettage (LC), subcutaneous laser treatment, and microwave-based therapy have been developed to treat osmidrosis. Few studies have compared these three techniques in relation to clinical efficacy, life quality improvement, and downtime.

Aims: We aim to evaluate clinical results and life quality improvement, in addition to downtime and complications, between these three techniques.

Risk assessment of excess drug and sunscreen absorption via skin with ablative fractional laser resurfacing : optimization of the applied dose for postoperative care.

The ablative fractional laser is a new modality used for surgical resurfacing. It is expected that laser treatment can generally deliver drugs into and across the skin, which is toxicologically relevant. The aim of this study was to establish skin absorption characteristics of antibiotics, sunscreens, and macromolecules via laser-treated skin and during postoperative periods.

Skin permeation of small-molecule drugs, macromolecules, and nanoparticles mediated by a fractional carbon dioxide laser: the role of hair follicles.

Purpose: To evaluate skin permeation enhancement mediated by fractional laser for different permeants, including hydroquinone, imiquimod, fluorescein isothiocyanate-labeled dextran (FD), and quantum dots.

Methods: Skin received a single irradiation of a fractional CO(2) laser, using fluence of 2 or 4 mJ with densities of 100 ∼ 400 spots/cm(2). In vitro and in vivo skin penetration experiments were performed.

Laser-assisted topical drug delivery by using a low-fluence fractional laser: imiquimod and macromolecules.

The aim of this study was to evaluate the ability of a low-fluence fractional erbium:yttrim-aluminum-garnet (Er:YAG) laser, with a wavelength of 2940 nm, for enhancing and controlling the skin permeation of imiquimod and macromolecules such as polypeptides and fluorescein isothiocyanate (FITC)-labeled dextran (FD). The in vitro permeation has been determined using a Franz diffusion cell, with porcine skin and nude mouse skin as the barriers. Hyperproliferative and ultraviolet (UV)-irradiated skins were also used as barrier models to mimic the clinical therapeutic conditions.

Fractional laser as a tool to enhance the skin permeation of 5-aminolevulinic acid with minimal skin disruption: a comparison with conventional erbium:YAG laser.

The aim of this study was to examine the in vitro skin delivery and in vivo protoporphyrin IX (PpIX) accumulation of topically applied 5-aminolevulinic acid (ALA) enhanced by a fractional laser pretreatment. This was achieved by applying an array of microscopic treatment zones (MTZ) to the skin by ablation of superficial stratum corneum in a determined area. Re-epithelialization determined by transepidermal water loss was completed within 1 day after fractional laser irradiation.

Acyclovir-induced neuropsychosis successfully recovered after immediate hemodialysis in an end-stage renal disease patient.

A 70-year-old man developed herpes zoster over the right L5-S2 region for 3 days and was admitted for acyclovir therapy. He had a medical history of rectal cancer status post-colostomy and end-stage renal disease undergoing thrice weekly hemodialysis. Without a prior loading dose, acyclovir 500 mg (7.
