Skin grafting treatment of adolescent lower limb avulsion injury.

BackgroundUnder the influence of various factors, the number of lower extremity avulsion injuries in adolescents is increasing year by year. The main modality of treatment is skin grafting. There are many types of skin grafting. Although many studies on skin grafting after avulsion injuries have been published in the past few decades, there are differences in the treatment options for adolescents with post avulsion injuries.Main bodyThorough debridement and appropriate skin grafts are essential for the surgical management of avulsion injuries for optimal prognosis. In the acquisition of grafts, progress has been made in equipment for how to obtain different depths of skin. The severity of the avulsion injury varies among patients on admission, and therefore the manner and type of skin grafting will vary. Especially in adolescents, graft survival and functional recovery are of great concern to both patients and physicians. Therefore, many efforts have been made to improve survival rate and activity.ConclusionThis review summarizes the principles of treatment of avulsion injuries, the historical development of skin grafts, and the selection of skin grafts, hoping to be helpful for future research.

Combination of Treatments in Nonsurgical Facelift Performance to Conduce a Case of Severe Photoaging

Introduction: Combination of techniques enables access to different depths in skin improving performance in nonsurgical face lift. Objective: To determine the effectiveness of the combination: intraoral 2940 nm erbium, followed by microneedled radiofrequency and microfocused ultrasound in severe photoaging. Materials and methods: Split-face study assessing combination combination of Intraoral Erbium: Yag Laser (IEL) 2940 nm pro-collagen, Microfocused Ultrasound and Microneedled Radiofrequency (Total Lift). Improvement was evaluated through photographic record. Results: After forty days of one laser treatment, significant improvement of photoaging from baseline was observed. The laser side showed, through the photographic record, great improvement in skin laxity, skin texture and wrinkles. Conclusion: The combination of techniques (Total Lift) is a promising new technology in the treatment of photoaging in patients with contraindications or do not want to perform surgery.

Surgical Pearl: Gauzabrasion—Abrading superficial slough with rough dressing gauze

Surgical procedures like dermabrasion, salabrasion, microdermabrasion, dermasanding, dermaplaning, etc, have been used to remove different depths of skin in order to rejuvenate the layered structure of skin. 1.

J Am Acad Dermatol. 2003; 48: 897-900 Abstract Full Text Full Text PDF PubMed Scopus (34) Google Scholar Various instruments or materials are required to achieve the different levels of cutaneous abrasion. The most superficial form of dermabrasion, using chemically inert crystals, has been termed microdermabrasion and has recently become very common. Because of its innate nature, the procedure of microdermabrasion can only be used on dry and intact skin surfaces. Wet areas, like chronic non-healing ulcers, may also require the removal of superficial layers of slough and dead necrotic tissue debris. The deeper layers of slough and necrotic tissue requiring wider excision may be replaced immediately by superficial necrotic slough, which harbors infection and thus retards granulation tissue formation. These wounds with recurrent superficial slough formation need to be treated with chemical desloughing agents like hydrogen peroxide, hypochlorite solution, hydrocolloid gel, and enzymatic agents like fibrinolysins, streptokinase, streptodornase, trypsin, and collagenase, etc. 3.

Pulsed photoacoustic study of the diffusion of chromophores in human skin.

The technique of pulsed photoacoustic spectroscopy was used to investigate the diffusion of chromophores in human skin. The kinetic of diffusion has been studied for five solutions at different concentrations in a mixture of chromophores, as used in commercial sunscreens. In addition to the classical macroscopic interpretation of the diffusion process, a new method is shown to give more detailed information on chromophore presence at different depths in skin. For the first time, results are expressed in the frequency domain by means of the Fourier transform applied to the photoacoustic signal. The spectra are discussed versus the depth in skin samples and the time of diffusion kinetics. This new method of data analysis is shown to be very useful for understanding the influence of the internal structure of a medium on the penetration rate of chromophores into skin.
