Optical Properties of Human Skin Phototypes and Their Correlation with Individual Angle Typology.

This study aims to correlate human skin phototypes with complete optical characterization (absorption, scattering, effective attenuation, optical penetration, and albedo coefficients) based on individual typology angle (ITA) values and colorimetric parameters. A colorimeter was used to group 12, fresh, human skin samples according to their phototype; the CIELAB color scale and ITA values were employed. An integrating sphere system and the inverse adding-doubling algorithm were applied during optical characterization, conducted from 500 to 1300 nm.

The role of the perioperative prone position in the low recurrence of pressure injuries in the pelvic region.

Objective: A pressure injury (PI) is a localised area of damage to the skin and/or underlying soft tissue as a result of a sustained mechanical loading. There are three key aetiological mechanisms to PI formation-direct cell deformation, inflammatory oedema and ischaemic damage-which are typically activated sequentially to drive a spiral of injury. This article discusses the role of the perioperative prone position as a rational approach to reducing the recurrence of pelvic PI after reconstructive surgery.

Treating complex palmar-plantar wounds using a bilaminar 'trapdoor' technique: a case series.

Objective: Due to the similarities of glabrous skin, the plantar region is an excellent donor area for covering complex palmar-plantar wounds. However, taking grafts from the plantar area often results in significant morbidity at the donor site or non-integration of the graft due to the greater thickness of the plantar corneal layer.

Method: This is a prospective case series including patients with burns or wounds who have been treated with a dermal graft using the bilaminar 'trapdoor' technique.

Comparison Between Two Strategies of Topical Treatment in Tar Burn: A Case Report.

The management of tar burns presents a wide range of possible approaches, and several strategies can be used to reduce the damage regarding the removal of tar adhered to the patient's skin. Tar residues should preferably be emulsified with solvent solutions. Due to the low incidence of tar burns, it has not yet been possible to select the appropriate agent for the removal of the adhered tar.

Does postauricular fascial flap reduce suture complications in otoplasty?

Numerous suture techniques and covering flaps have been described to minimize complications related to sutures in otoplasty. The split postauricular fascial flap is one of such techniques, and it has been used to pad otoplasty suture. The aim of this study was to evaluate complications related to nonabsorbable cartilage sutures in otoplasty, using a variation of the split postauricular fascial flap.

Objective: This study aims to report the use of the unilateral pectoralis major muscle flap for the treatment of the sternal wound dehiscence.

Methods: A retrospective study including patients who underwent unilateral pectoralis major muscle flap was performed for the treatment of sternotomy dehiscence due to coronary artery bypass, valve replacement, congenital heart disease correction and mediastinitis, between 1997 and 2016. Data from the epidemiological profile of patients, length of hospital stay, postoperative complications and mortality rate were obtained.

Gluteal Augmentation With Intramuscular Implants in Patients With Human Immunodeficiency Virus With Lipoatrophy Related to the Use of Antiretroviral Therapy.

Introduction: Lipodystrophy syndrome associated with highly active antiretroviral therapy (HAART) may lead to low self-esteem and poor compliance with the drug treatment on patients infected with human immunodeficiency virus (HIV), which is a matter of concern for the health system. The aim of this study was to evaluate patients with HIV submitted to gluteal augmentation with intramuscular silicone implants to correct gluteal lipoatrophy related to the use of HAART.

Methods: This is a retrospective evaluation of 10 patients submitted to gluteal augmentation with intramuscular silicone implant for correction of gluteal lipoatrophy related to the use of HAART, operated between 2012 and 2015.

Negative pressure therapy for the treatment of complex wounds.

The objective of this study is to evaluate the effectiveness of negative pressure therapy (NPT) in the treatment of complex wounds, with emphasis on its mechanisms of action and main therapeutic indications. We searched the Pubmed / Medline database for articles published from 1997 to 2016, and selected the most relevant ones. The mechanisms of action of NPT involveboth physical effects, such as increased perfusion, control of edema and exudate, reduction of wound dimensions and bacterial clearance, and biological ones, such as the stimulation of granulation tissue formation, microdeformations and reduction of Inflammatory response.

Gluteal Augmentation with Silicone Implants: A New Proposal for Intramuscular Dissection.

Background: Gluteoplasty has gained notoriety over the last decades, which has motivated the development of various surgical techniques. Nevertheless, the fear of dissection of the intramuscular plane without direct visualization may inhibit learning and development of gluteal augmentation with implants. Moreover, literature detailing the technical steps of intramuscular dissection for the construction of the implant pocket is scarce.

Evidences of autologous fat grafting for the treatment of keloids and hypertrophic scars.

Introduction: Since the 1980s, the use of autologous fat grafting has been growing in plastic surgery. Recently, this procedure has come to be used as a treatment for keloids and hypertrophic scars mainly due to the lack of satisfactory results with other techniques. So far, however, it lacks more consistent scientific evidence to recommend its use.

Revisiting Escharotomy in Patients With Burns in Extremities.

Escharotomy incisions must be made in the inelastic skin eschar that is typical of circumferential third-degree burns. Later, the necrotic tissue must be debrided and substituted with a skin graft. Many reports on this topic have revealed that concepts and techniques vary widely.

Bronchial fistula closure with negative pressure wound therapy: a feasible and cost-effective treatment.

Treatment of bronchial fistula (BF) after pulmonary lobectomy is a challenge.
