Breast asymmetry is a common finding in developing adolescents. In select cases, there is maldevelopment of 1 or both breasts, which persists into adulthood and causes significant negative impact on life. Various surgical techniques (eg, breast augmentation/reduction) and nonsurgical techniques (eg, bras/gel inserts) are currently in practice to achieve breast symmetry. We describe a unique case of a young lady with Poland's syndrome, who presented with a lateralized right breast. We have used a V-Y advancement flap, along with a breast implant, to medialize the breast and achieve symmetry in contour and volume, followed by medialization of the nipple areolar complex...

Breast augmentation is the most common cosmetic surgery in the United States. Squamous cell carcinoma (SCC) of the breast raises suspicion of possibly metastatic origin. Here, we report an unusual case of implant-associated SCC of the breast post silicone gel breast implant. The patient is a 46-year-old female with SCC of the breast. She initially had silicone gel breast implantation for breast augmentation in 1995. She had multiple revisions due to swelling and hardening. In 2016, she underwent bilateral prosthesis explantation and bilateral capsulectomy...

In response to a growing demand for simultaneous detection of multiple proteins in a single sample, multiplex immunoassay platforms have emerged at the forefront of proteomic analysis. In particular, detections using graphically encoded hydrogel microparticles synthesized via flow lithography have received attention for integrating a hydrogel, a substrate that can provide enhanced kinetics and high loading capacity, into the bead-based multiplex platform. Currently, the method of microparticle functionalization involves copolymerization of antibodies with the gel during particle synthesis...

The effect on protein conformation and thermal stability was studied for β-Galactosidase (β-Gal) encapsulated in the nanopores of a silicate matrix (Eβ-Gal ). Circular dichroism spectra showed that, compared with the enzyme in buffer (Sβ-Gal ), Eβ-Gal exhibited a higher content of α-helix structure. Heating Eβ-Gal up to 75 °C caused a decrease in the content of β-sheet structure and additional augments on Eβ-Gal components attributed to helical content, instead of the generalized loss of the ellipticity signal observed with Sβ-Gal ...

In this study, polysaccharide-based hydrogel wound dressings containing in situ synthesized gold nanoparticles (AuNPs) were prepared by using a simple, fast and green protocol. The prepared hydrogels were characterized with UV-vis and infrared spectroscopy (FT-IR), and dynamic light scattering (DLS). The rheological and swelling properties and the feasibility to scale-up the wound dressing production from the lamination of the prepared hydrogel on non-woven fabric were also investigated. UV-vis spectra confirmed the AuNPs synthesis and the DLS results exhibited an increase in the size of AuNPs with increasing the initial Au3+ concentration...

Despite the controversy regarding penile augmentation (PA), glans penis augmentation (GPA) is used in penile reconstructive surgery in selected patients with small glans penis. Since 2003, injectable hyaluronic acid (HA) gel has been used for GPA. The attractiveness of HA gel fillers and interest in this technique have led to the use of other fillers for GPA, particularly irreversible fillers that improve the longevity of HA gels. Conversely, indirect glans augmentation via implantation of dermofat grafts or scaffolds between the corpus spongiosum and the distal tip of the corpus cavernosum is used to overcome poor longevity of the gel and glans surface undulation, which are the primary limitations of GPA using HA gel...

We report the design, synthesis and efficacy of a new class of gel-like nano-carrier, or 'nanogel', prepared via templated electrostatic assembly of anionic hyaluronic acid (HA) polysaccharides with the cationic peptide amphiphile poly-L-lysine (PLL). Small molecules and proteins present during nanogel assembly become directly encapsulated within the carrier and are precisely released by tuning the nanogel HA:PLL ratio to control particle swelling. Remarkably, nanogels exhibit versatile and complimentary mechanisms of cargo delivery depending on the biologic context...

Breast augmentation using implants is the most common aesthetic and reconstructive breast surgical procedure. Complications such as implant rupture maybe related to surgical technique and damage to the implant. Autologous fat transfer (lipofilling) using metallic cannulae has become a standard adjunctive, yet there is little evidence on lipofilling safety in the presence of implants. The aims of this study are to verify the effects of different cannulae and to quantify the forces applied by surgeons during lipofilling...

Breast implants have been shadowed in controversy since their introduction to the market; however, they represent a multi-million dollar industry and play a critical role both for cosmetic augmentation and enhancement and for reconstruction following treatment for cancer. With advancements in technology, breast implants have evolved tremendously over the years. Further, with the cessation of the FDA implemented moratorium on silicone, the use of silicone implants has grown exponentially over the years. Novel designs in the outer shell, breast implant fill particularly the cohesivity of the silicone gel, texturing of the outer shell, and the shape and projection of breast implants have produced a broad array of implants that can be employed by plastic and reconstructive surgeons to maximize outcomes for patients...

The engineering of breast implants for both augmentation and reconstruction is centered on facilitating optimal aesthetic results pleasing to the patient, while minimizing both short- and long-term complications. Some of the key individual design elements that have been the primary focus over time have included gel cohesivity, shell thickness, shell surface, and implant gel fill. A review of these separate elements points to the potential benefits of increased focus on a combined overall performance perspective for engineering of new implants as exemplified in the recently introduced MemoryGel Xtra Breast Implants...
