DermACELL: a novel and biocompatible acellular dermal matrix in tissue expander and implant-based breast reconstruction

BACKGROUND: Acellular dermal matrices present a new alternative to supporting expanders and implants for breast reconstruction in breast cancer patients following mastectomy. However, some studies have suggested that acellular dermal matrix may increase the complication rates in certain clinical settings. DermACELL acellular dermal matrix offers advanced processing in order to attempt to decrease bio-intolerance and complications. METHODS: Ten consecutive patients that presented for breast reconstruction and were candidates for tissue expanders underwent the procedure with the use of an acellular dermal matrix. The patients underwent postoperative expansion/adjuvant cancer therapy, then tissue expander exchange for permanent silicone breast prostheses. Patients were followed through the postoperative course to assess complication outcomes. Histologic evaluation of host integration into the dermal matrix was also assessed. RESULTS: Of the ten patients, eight completed reconstruction while two patients failed reconstruction. The failures were related to chronic seromas and infection. Histology analysis confirms rapid integration of mesenchymal cells into the matrix compared to other acellular dermal matrices. CONCLUSIONS: Based on our observations, DermACELL is an appropriate adjunct to reconstruction with expanders. Histological analysis of vascularization and recellularization support the ready incorporation of DermACELL into host tissue. Level of Evidence: Level IV, therapeutic study

Search for light resonances decaying to boosted quark pairs and produced in association with a photon or a jet in proton–proton collisions at √s=13 TeV with the ATLAS detector

This Letter presents a search for new light resonances decaying to pairs of quarks and produced in association with a high-pT photon or jet. The dataset consists of proton–proton collisions with an integrated luminosity of 36.1 fb−1at a centre-of-mass energy of √s=13TeV recorded by the ATLAS detector at the Large Hadron Collider. Resonance candidates are identified as massive large-radius jets with substructure consistent with a particle decaying into a quark pair. The mass spectrum of the candidates is examined for local excesses above background. No evidence of a new resonance is observed in the data, which are used to exclude the production of a lepto-phobic axial-vector Z boson

Infection Prophylaxis Update

The use of prophylactic antibiotics in surgery has been debated for numerous years. Although their indications have been elucidated in the general surgery literature, their role in plastic surgery has yet to be clearly defined. Although the incidence of surgical site infections in clean, elective plastic surgery procedures has been reported to be as low as 1.1%, the use of antibiotics has surged over the past 20 years. Much of the increased use has been attributed to common surgical practice and fear of legal ramifications rather than empirically based data. In contrast, there remain numerous physicians who argue against routine antibiotic use in plastic surgery. This article summarizes the recent literature on infection prophylaxis and advises physicians to consider relative risks and benefits when deciding which patients should receive prophylactic antibiotics

Composite Arteriovenous Radial Conduit Flap for Lower Limb Reconstruction

WOS: 000402766100010PubMed ID: 28507855In complex lower limb trauma, the healthy recipient vessels can be far from the defect to be reconstructed due to the usually high-energy injury sustained. The use of vein grafts, either directly or in the form of arteriovenous loops, is the usual solution in these cases. In the vein graft donor-depleted patient, other options are required; the composite arteriovenous radial conduit flap may be a useful resort in these situations

Variations of Structural Components: Specific Intercultural Differences in Facial Morphology, Skin Type, and Structures

Analysis of the differences in facial morphology and skin structure and tone among ethnic groups within the realm of plastic surgery is relevant due to the increasing number of ethnic individuals seeking cosmetic surgery. Previous classifications of ideal facial morphologic characteristics have been revised and challenged over the years to accurately reflect the differences in facial structure that are aesthetically pleasing to individuals of differing ethnic groups. The traditional neoclassic canons reflected the European Caucasian facial morphology and cannot be used to classify facial characteristics in ethnic groups due to drastic differences in measurement and proportion. In addition, differences in biophysiologic properties of ethnic skin types influence the progression of aging and the ability of skin to withstand environmental insults. Thickness of the stratum corneum, water content, and melanin composition are important factors that were analyzed in varying ethnic groups. Although it appears that Caucasian Americans are subject to earlier onset of skin wrinkling and sagging than are African Americans due to thinner stratum corneum layers and decreased water content, more research needs to be conducted to be inclusive of other ethnic groups. These data will enable plastic surgeons to treat these groups more effectively while preserving their unique characteristics
