This study aimed to review the literature to compare therapeutic strategies to prevent common adverse events in abdominoplasty.

Effectiveness of negative-pressure wound therapy with instillation compared to standard negative-pressure wound therapy and traditional gauze layer dressing for the treatment of acute traumatic wounds: A randomized controlled trial.

Background: Acute traumatic wounds often require prolonged healing time and hospitalization. Negative-pressure wound therapy with instillation and dwell time (NPWTi-d) has demonstrated effectiveness in accelerating patient healing over traditional NPWT, and its benefits are well established in the treatment of chronic infected wounds. However, randomized studies examining the use of NPWTi-d in acute traumatic wounds are scarce.

Treatment of facial lipodystrophy induced by a biologic agent (IPD-1): a literature review.

Agents that inhibit programmed cell death (IPD-1) in T lymphocytes are indicated for patients with advanced cancer. However, some individuals may develop endocrinological conditions, such as diabetes, thyroid dysfunction, and lipodystrophy, after treatment. This systematic review and case report of IPD-1 lipodystrophies describes a patient who received nivolumab treatment for advanced clear cell renal carcinoma and subsequently developed diabetes as well as facial and body lipodystrophy.

Effect of Early Postoperative Mobilization on Functional Recovery, Hospital Length of Stay, and Postoperative Complications After Immediate Internal Pudendal Artery Perforator Flap Reconstruction for Irradiated Abdominoperineal Resection Defects: A Prospective, Randomized Controlled Trial.

Background: Patients undergoing perineal defect reconstruction with the internal pudendal artery perforator (IPAP) flap traditionally face 5 days of postoperative bed rest (BR) to minimize surgical risks. However, prolonged BR can exacerbate postoperative physiologic changes such as increased fatigue, reduced body mass, and declining lung function, while also leading to complications such as pneumonia, delirium, deep vein thrombosis, and pressure injuries. This study assessed the effectiveness, feasibility, and safety of an adapted early mobilization (EM) program for these patients.

Ethnic Rhinoplasty in the Brazilian Population: Current Concepts.

Introduction: The large mixture of races in Brazil gives the nose its distinctive composition, which makes rhinoplasty difficult for these patients. Every patient should have their anatomy thoroughly examined on an individual basis, as there is no unique strategy that works for all situations.

Methodology: This is a narrative overview of the last 10 years' worth of literature that describes the ethnic traits of each nose, with a particular emphasis on the Brazilian nose, and talks about the major surgical approaches that can be applied in these situations.

Does the Webster's Triangle Preservation Really Matter? A Retrospective Analysis of the Low-to-Low Osteotomies in the Head of the Inferior Turbinates.

Background: Osteotomies are important maneuvers in the plastic surgeon's arsenal for the nasal dorsum treatment. However, there is a concern regarding a possible medialization of the inferior turbinate's heads and narrowing of the internal nasal valve if the Webster's triangle is not preserved.

Objectives: To analyze the mobilization of the inferior turbinates during primary rhinoplasty after lateral osteotomies.

Methotrexate-Loaded solid lipid nanoparticles enhance the viability of cutaneous flaps: potential for surgical wound healing.

Skin flaps are employed to cover cutaneous denuded surfaces, but ensuing flap necrosis often occurs. Previously, rats with myocardial infarction treated with lipid-core nanoparticles (LDE) loaded with methotrexate (MTX) improved myocardial irrigation and reduced necrosis. Here, the aim was to investigate the efficacy of LDE-MTX to preserve the viability of cutaneous flaps and its implications for surgical wound healing.

Effect of Hyperbaric Oxygen Therapy and Adipocyte Stem Cell on the Viability of Degloving Injury: A Murine Model.

Introduction: Degloving soft tissue injuries (DSTIs) involve skin and tissue detachment from muscle or fascia. Surgical treatments exist, but they cannot prevent necrosis.

Objective: Our aim was to investigate the effects of hyperbaric oxygen therapy (HOT) and adipocyte stem cell (ASC) treatment on tissue viability in degloving injuries in a murine model.

Enrichment of Fat Graft with Association of ASC and Nanofat in an Animal Model.

Introduction: Fat graft (FG) absorption rate varies from 20 to 80% in two years. Recently, several bioengineering techniques were applied to improve FG retention rate. Numerous studies investigated the use of adipocyte-derived stem cells (ASC) as FG enrichment.

Effect of ASC Injection in the Inflammatory Reaction in Silicone Implant Capsule: Animal Model.

Background: Capsular contracture is a common complication affecting about 80% of patients who receive radiotherapy after breast reconstruction with silicone prostheses. This study examines the use of adipocyte stem cells (ASCs) to treat capsular contracture.

Methods: Thirty rats were operated on to implant a minisilicone prosthesis in the dorsal region.

Surgical treatment of sacral pressure injury in ambulating patients during the COVID-19 pandemic: A prospective cohort with complications analysis and elaboration of a surgical treatment protocol.

Background: The sudden increase of intensive care unit patients during the coronavirus pandemic led to an increase in the incidence of sacral pressure lesions. Despite being ambulating patients, in many cases the lesions were deep (Grade III and IV), mainly due to the long-term intubation and being bedridden during the pandemic. Most of these wounds necessitated surgical repair.

Microneedling in the Treatment of Post-burn Hypertrophic Scars.

Introduction: Post-burn hypertrophic scars are an important cause of physical discomfort, limitation of movements, psychological disorders, low self-esteem and reduced quality of life. Treatment for this condition is complex and involves several options. Microneedling, also known as minimally invasive percutaneous collagen induction, is an affordable minimally invasive option that can be combined with other treatments, including ablative ones.

Adipose tissue-derived stem cells as a therapeutic strategy for enterocutaneous fistula: an experimental model study.

Purpose: Enterocutaneous fistula (ECF) is a condition in which there is an abnormal connection between the intestinal tract and the skin. It can lead to high morbidity and mortality rates despite the availability of therapeutic options. Stem cells have emerged as a potential strategy to treat ECF.

Surgical treatment of sacral pressure wounds in patients with COVID-19: A case series.

Introduction: The COVID 19 pandemic has resulted in an increased number of patients requiring intubation and intensive care.

The Influence of the Superficial Venous System on DIEP Flap Drainage in Breast Reconstruction.

Background:  Autologous tissue has become the gold standard in breast reconstruction. The use of a deep inferior epigastric perforator (DIEP) flap has the advantages of giving a natural appearance to the reconstructed breast and being associated with lower morbidity at the donor site when compared with the transverse rectus abdominis myocutaneous flap. Venous complications such as venous thrombosis and insufficiency remain the main causes of flap loss and surgical revisions.
