A case report and a call for early recognition: post-operative Pyoderma Gangrenosum after breast-conserving surgery in a locally advanced breast tumor.

We present a case of a patient addressed to our plastic surgery department after a breast tumor resection and subsequent necrosis and ulceration of the right breast. A diagnosis of pyoderma gangrenosum was made based on the clinical criteria, early recognition resulted in complete recovery without further reconstructive surgery.

Skin Perfusion After Hemostatic Net: An Anatomic and Radiologic Study in a Cadaver Model.

Background: The hemostatic net is a recent technique initially developed to reduce the occurrence of postoperative hematomas following facelift procedures. Its applications have expanded to include skin redraping, deep plane fixation, and other areas beyond the face. However, no experimental study has investigated its effect on skin blood supply.

Bilateral Pedicled Scrotal Flaps as an Alternative to Skin Graft in Penile Shaft Defects Repair.

Objective: To analyze surgical and functional outcomes of bilateral pedicled scrotal flaps for penile shaft reconstruction.

Materials And Methods: A retrospective analysis was performed on 22 patients who underwent penile shaft reconstruction with bilateral pedicled scrotal flaps between 2009 and 2017. Demographics, peri-operative data, and surgical complications were collected.

Determining the outcomes of urethral construction in phalloplasty.

Objective: To evaluate the surgical and functional outcomes of urethral reconstruction associated with phalloplasty, depending on the surgical techniques and patient history.

Materials And Methods: We conducted a single-centre retrospective study including 89 patients who underwent phalloplasty with urethral reconstruction between 2007 and 2018. Patients included were trans-male patients undergoing gender-affirming surgery and cis-male patients undergoing penile reconstruction after trauma, congenital malformation, or cancer.

Microsurgical phalloplasty: Anatomical study evaluating the use of the external pudendal vessels as recipients.

The inferior epigastric artery (IEA) is commonly used as a recipient vessel in microsurgical phalloplasty but its use can be associated with abdominal parietal complications (hernia, bulging). To preclude such complications and avoid involvement of the femoral artery, we assessed an external pudendal artery (EPA) as a recipient vessel. We studied the disposition of the external pudendal system and its general anatomy.

Functional and surgical outcomes after phalloplasty in cis men.

Purpose: Evaluate the surgical outcomes along with a comprehensive assessment of functional outcomes in cis men (non-trans) who underwent phalloplasty.

Methods: All consecutive cis men who underwent phalloplasty from 2008 to 2018 for penile insufficiency due to various causes were included. These underwent phalloplasty by either a radial forearm free flap (RFFF) or suprapubic phalloplasty (SPP).

Revisiting Mg solubility in CuO nanorods: limit probed by neutron diffraction and effect on the particle toxicity towards bacteria in water.

Both nanometer-sized CuO and MgO particles exhibit bactericidal activities against and , two bacteria causing healthcare-associated infections. The solid solution CuMgO is potentially interesting for biomedical applications as one of the compositions could have a much higher bactericidal activity than the parent CuO and MgO oxides considered separately. But, to date, no Vegard's law proves the real existence of such a solid solution.

"Reverse tensor fascia latae perforator flap for reconstruction of knee defect: Anatomic study by computed tomographic angiography and a case report".

Background: Reverse anterolateral thigh perforator (ALTp) pedicle flap can be used to reconstruct perigenicular defect thanks to the anastomoses between the descending branch of the lateral circumflex femoral artery (LCFA) and the perigenicular network. In a few cases, however, patients do not present any ALTp. We hypothesized that, in such cases, an adjacent perforator, the tensor fascia latae perforator (TFLp), emerging from the LCFA ascending branch, could be used instead.

Understanding the bactericidal mechanism of Cu(OH) nanorods in water through Mg-substitution: high production of toxic hydroxyl radicals by non-soluble particles.

To date, there is still a lack of definite knowledge regarding the toxicity of Cu(OH) nanoparticles towards bacteria. This study was aimed at shedding light on the role played by released cupric ions in the toxicity of nanoparticles. To address this issue, the bactericidal activity of Cu(OH) was at first evaluated in sterile water, a medium in which particles are not soluble.

Chest wall infarction following bilateral internal thoracic harvesting for coronary revascularization in a patient with previous aortic abdominal aneurysm surgery: A rare complication.

A 75 years old man with previous aortic abdominal aneurysm surgery through a transverse laparotomy underwent bilateral internal thoracic artery to coronary artery bypass grafting. He immediately thereafter developed a severe chest and upper abdominal walls ischemia with metabolic acidosis, and finally deep sternum wound infection and upper abdominal wall necrosis. He benefitted from sternal reconstruction and vaccum assisted treatment, with delayed pectus major flap reconstruction.

Hydration and bactericidal activity of nanometer- and micrometer-sized particles of rock salt-type MgCuO oxides.

Copper substitution together with nano-structuring are applied with the aim to increase the bactericidal performances of the rocksalt-type MgO oxide. The partial substitution of magnesium ions with Cu has been successfully achieved in both micrometer- and nanometer-sized particles of MgO up to 20 mol% in increments of 5 mol%. Microstructural analyses using the Integral Breadth method revealed that the thermal decomposition of the single source precursor MgCu(OH)(CO).

Trans-oral versus cervico-facial lift approach for mandibular angle resection in facial feminization: A retrospective study.

Introduction: Mandibular angle resection is an important procedure in facial feminization surgery. Two different approaches are described: trans-oral and cervico-facial lift (CFL) approaches. The aim of the study was to compare surgical outcomes and patient's satisfaction between the two approaches.

ALGINATE versus NPWT in the Preparation of Surgical Excisions for an STSG: ATEC Trial.

Unlabelled: A calcium alginate dressing (ALGINATE) and negative pressure wound therapy (NPWT) are frequently used to treat wounds which heal by secondary intention. This trial compared the healing efficacy and safety of these 2 treatments.

Methods: This randomized, non-inferiority trial enrolled patients who underwent skin excision (>30 cm), which was left open to heal by secondary intention.

Enhanced bactericidal activity of brucite through partial copper substitution.

Brucite Mg(OH) belongs to a family of two-dimensional compounds with a CdI-type structure built up from layers of edge-sharing octahedra delineating 2D galleries. In the current study, nanometer-sized platelets of copper substituted Mg(OH) were prepared by co-precipitation at room temperature in mixed alkaline (NaOH/NaCO) medium. Very weak substitution of a few hydroxyl ions by carbonate groups was highlighted at first by infrared spectroscopy and then quantified by thermogravimetric (TG) and mass spectrometric (MS) evolved gas analyses.

Transverse Facial Artery Perforators: Anatomical, Two- and Three-Dimensional Radiographic Study.

Background: Increased anatomical knowledge of skin vascularization, such as the recent description of angiosome and perforasome concepts, has led to important innovations in flap surgery. In this sense, few studies have been performed on face vascularization especially for facial artery perforasomes. The aim of this study was to analyze the number, size, and localization of transverse facial artery perforators and their perfusion area.

Pressure ulcer-related pelvic osteomyelitis: evaluation of a two-stage surgical strategy (debridement, negative pressure therapy and flap coverage) with prolonged antimicrobial therapy.

Background: A two-stage surgical strategy (debridement-negative pressure therapy (NPT) and flap coverage) with prolonged antimicrobial therapy is usually proposed in pressure ulcer-related pelvic osteomyelitis but has not been widely evaluated.

Methods: Adult patients with pressure ulcer-related pelvic osteomyelitis treated by a two-stage surgical strategy were included in a retrospective cohort study. Determinants of superinfection (i.

Evaluation of Three Devices for the Isolation of the Stromal Vascular Fraction from Adipose Tissue and for ASC Culture: A Comparative Study.

Adipose-derived stem/stromal cells (ASCs) reside in the stromal vascular fraction (SVF) of adipose tissue (AT) and can be easily isolated. However, extraction of the SVF from lipoaspirate is a critical step in generating ASC, and semiautomated devices have been developed to enhance the efficacy and reproducibility of the outcomes and to decrease manipulation and contamination. In this study, we compared the reference method used in our lab for SVF isolation from lipoaspirate, with three medical devices: GID SVF-1™, Puregraft™, and Stem.

Hand Allograft Saved by an Ultrathin Groin Flap.

We report a case of a young double-hand allotransplant patient who presented with a full-thickness skin necrosis of the dorsum of the left hand after vascular compromise of the allotransplantation. Considering the lack of viable dorsal tissue overlying the extensor tendons and the need for early hand rehabilitation, an ultrathin pedicled groin flap was used for the coverage. This procedure resulted in salvaging the allotransplantation, and the patient was able to successfully return to work after his surgery.

Intradermal injection of human adipose-derived stem cells accelerates skin wound healing in nude mice.

Background: The use of stem cells from adipose tissue or adipose-derived stem cells (ASCs) in regenerative medicine could be an interesting alternative to bone marrow stem cells because they are easily accessible and available in large quantities. The aim of this study was to evaluate the potential effect of ASCs on the healing of 12 mm diameter-excisional wounds (around 110 mm(2)) in nude mice.

Methods: Thirty nude mice underwent surgery to create one 12-mm excisional wound per mouse (spontaneous healing, n = 6; Cytocare® 532, n = 12; ASCs, n = 12).

In vitro and in vivo biocompatibility, bioavailability and tolerance of an injectable vehicle for adipose-derived stem/stromal cells for plastic surgery indications.

Soft tissue reconstruction is a challenge in plastic surgery, when replacing lost materials and correcting contour defects. Many permanent and temporary fillers have been used to restore the volume of these lesions, but often with poor results and even complications. Adipose-derived stem/stromal cells (ASCs) and adipose tissue engineering have been suggested as valuable alternatives.

Superficial femoral artery perforator flap: anatomical study of a new flap and clinical cases.

Background: The medial thigh has been infrequently studied as a donor site for pedicled or free flaps. In their previous studies, the authors observed a direct cutaneous branch from the superficial femoral artery. This study aimed to investigate the anatomy and potential possibility for flap elevation (the midmedial thigh flap) on this direct branch of the superficial femoral vessels.
