Photobiomodulation with laser and led on mesenchymal stem cells viability and wound closure in vitro.

Mesenchymal stem cells can differentiate into specific cell lineages in the tissue repair process. Photobiomodulation with laser and LED is used to treat several comorbidities, can interfere in cell proliferation and viability, in addition to promoting responses related to the physical parameters adopted. Evaluate and compare the effects of laser and LED on mesenchymal cells, with different energy doses and different wavelengths, in addition to viability and wound closure.

Comparative cohort analysis of pressure ulcer/injury in intensive care unit patients before and during the COVID-19 pandemic.

COVID-19 has emerged as a global pandemic leading to an increase in hospitalization and intensive care unit (ICU) admissions worldwide. Due to severe acute respiratory distress syndrome (ARDS), many patients require prone positioning, which is associated with increased pressure ulcer/injury (PU/PI) incidence. COVID-19 pathophysiology may favor the occurrence of PU/PI due to hypoxemia, inflammatory status, and vasculopathy.

Effects of therapeutic ultrasound and paraffin with or without vacuum massage on biomechanical properties of grafted skin after burn: a randomized controlled trial.

Objective: This study aimed to compare the effects of therapeutic ultrasound and paraffin with or without vacuum massage on the biomechanical properties of grafted skin after a burn.

Methods: A total of 44 patients with deep second- and third-degree burns, with a mean age of 35.89 (±11.

The role of the unilateral pectoralis major muscle flap in the treatment of deep sternal wound infection and dehiscence.

Deep sternal wound infection and dehiscence has been classified as complex wound, and its treatment is a challenge for the surgeon. There are many flap choices for its treatment, each one having advantages and drawbacks. The article by Wang et al.

Intra- and inter-examiner reliability of digital images of skin donor areas in burns.

Objective: The main objective of this study was to evaluate intra- and inter-rater reliability in the analysis of digital images of donor areas for skin in burn patients using the CaPAS plugin in the ImageJ®.

Methods: Donor sites were reviewed by two independent reviewers in duplicate. The capture of images was standardized on the same device and distance (with a millimeter ruler), without a flash.

Evaluation of contraction of the split-thickness skin graft using three dermal matrices in the treatment of burn contractures: A randomised clinical trial.

Burn injuries commonly result in serious sequelae (such as skin contractures) in surviving patients, for which no single optimal solution is known. The goal of this study was to compare the late contraction of autologous skin grafts with or without dermal matrices used in the treatment of patients with burn contractures. This parallel design prospective, randomised and controlled clinical trial included patients with burn contracture treated using autologous skin grafts and dermal matrix.

The role of negative pressure wound therapy (NPWT) on the treatment of pyoderma gangrenosum: A systematic review and personal experience.

Pyoderma gangrenosum (PG) is a rare painful ulcerative neutrophilic inflammatory skin disease, necessitating a high level of diagnostic suspicion associated with appropriate treatment to avoid progression. Negative pressure wound therapy (NPWT) has been efficiently used in the treatment of different types of wounds. However, the role of NPWT in the management of PG is still controversial, due to the risk of the pathergy phenomenon.

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.

Analysis of Adipose-Derived Stem Cells from Different Donor Areas and Their Influence on Fibroblasts In Vitro.

Background: New regenerative treatments have emerged with the use of multipotent mesenchymal cells, with special interest in adipose-derived stem cells (ADSCs). In recent years, studies that have sought to identify possible quantitative or qualitative differences in ADSCs derived from different donor subcutaneous adipose tissue have shown divergent results making the determination of a preferential donor area still considered inconclusive.

Materials And Methods: The number of ADSCs present in the adipose tissue collected by liposuction was quantified between five different body areas from 17 women, by means of the CFU-F assay and to investigate possible qualitative differences in the ADSCs from these different areas by analyzing: cell surface markers, cell kinetics, action of the supernatant produced by ADSCs from different body areas on fibroblast migration and, finally, differences in the secretome present in the supernatant produced by these cells.

Acute otitis externa because of negative pressure wound therapy applied over the head and ear canal for scalping treatment.

Scalping is considered a complex wound with difficult treatment, requiring early surgical intervention, reconstructive plastic surgery, and a multidisciplinary team. The reconstruction of the scalp frequently requires a combination of therapies, including temporary coverage, such as negative pressure wound therapy (NPWT). Complications of NPWT, such as bleeding, infection, and pain, have been described.

Early Application of Microsurgical Flaps in the Electric Burns of Extremities: A Two Institutional Case Series.

Some groups have avoided early microsurgical flaps in electrical burns under the pretext of injury to the microvasculature, which could increase vascular thrombosis. However, this option frequently results in amputation of the extremity. This study aims to evaluate the early application of microsurgical flaps for the treatment of electrical burns of extremities.

High-voltage electric stimulation of the donor site of skin grafts accelerates the healing process. A randomized blinded clinical trial.

Introduction: Severe burns benefit from skin grafting, and grafting surgery is of great importance in the treatment of these injuries. As a result, there is formation of an additional wound at the donor site, which is painful and susceptible to infection. However, the therapeutic approach to these problems at donor sites for skin grafting is insufficiently explored in the literature.

Unilateral pectoralis major muscle flap for the treatment of sternal wounds due to Ludwig's angina.

Necrotising descending mediastinitis may rarely originate from Ludwig's angina, which is an infection of the submandibular space. The use of the bilateral pectoralis major muscle flap for the treatment of sternal wound dehiscence is common, but reports of the unilateral application of this flap are scarce. This study aims to report the use of the unilateral pectoralis major muscle flap for the treatment of sternotomy dehiscence in a patient with mediastinitis due to Ludwig's angina.

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.

A randomized controlled trial of an educational programme with telephone reinforcement to improve perceived health status of Brazilian burn victims at 6-month post discharge.

Aim: The aim of this study was to compare health status, self-efficacy, symptoms of depression and anxiety and post-traumatic stress between two groups of burn victims receiving information on self-care through routine care or an educational programme with telephone reinforcement.

Background: Self-care post discharge is an important factor on quality of life of burn victims. Reinforcement of self-care programme via telephone follow-up might improve self-efficacy and general health perception in burn victims.
