BACKGROUND: Silicone breast implants from the French manufacturer Poly Implants Prosthèse (PIP) were recalled from the European market after the French regulator has revealed the implants contain non-medical-grade silicone filler. In December 2011, following a large increase in reported rupture rate and a possible cancer risk, the French Ministry of Health recommended consideration of the PIP explantation, regardless of their condition. In 2012, the Israel Ministry of Health recommended to replace the implants only upon suspected implant rupture...

BACKGROUND: The phyllodes tumour of the breast comprises about 0.5% of all neoplasms of the breast. CASE REPORT: we present the case of a female patient (55 years old) suffering from giant phyllodes tumour (>10cm) of the left breast, who underwent Skin Reducing Mastectomy (SRM) and reconstruction with silicone breast implant (Bostwick Technique). DISCUSSION AND CONCLUSION: In selected patients with large sized breasts (C-D cup) and poor surface area of skin involved, a valid technique in the treatment of this pathology is the Skin-Reducing Mastectomy and immediate reconstruction with implants (DTI=direct to implant)...

The aim of the current study was to determine whether the MWCNT-based scaffold has a suitable structure for cell growth and provides a biocompatible environment for human MDA-MB-231 cell lines. MWCNT-based nanostructured scaffolds were produced by plasma-enhanced chemical vapor deposition (PECVD) technique. MDA-MB-231 cells were seeded on MWCNTs-textured silicon scaffolds and on pristine silicon surfaces. After 1 week of culturing, the scaffolds were prepared for SEM analysis and immunocytochemical staining was performed for the two groups (MWCNT scaffold and pristine silicon surface), using MMP-2, MMP-9, PI3K, AKT and NF-κB primary antibodies...

Soft-tissue augmentation and implants are increasingly seen by the radiologist as more techniques emerge for a variety of indications and locations. Some surgical and implant procedures are performed for purely cosmetic reasons in otherwise healthy patients seeking to improve their body image, and some are performed for reconstruction after cancer or other chronic illnesses. Abdominoplasty, liposuction, and autologous fat grafting can be performed for abdominal and gluteal contouring. Injection of liquid injectable silicone has historically been fraught with legal issues, although it continues to be used for augmentation in a variety of anatomic locations...

Breast cancer is one of the most serious diseases, posing threats to women's physical and mental health. Gene therapy has been gradually regarded as an important part of tumor therapeutics. In the present study, the breast cancer‑specific gene 1‑small interference RNA (BCSG1‑siRNA) plasmid was designed, then encapsulated by chitosan‑silicon dioxide nanometer carriers. The results demonstrated a successful encapsulation of BCSG1‑siRNA in chitosan‑silicon dioxide nanoparticles (encapsulation efficiency exceeded 90%)...

Background: Breast implants can be characterized by their fill material, surface texture, or shape. Whereas long-term good quality studies have provided evidence for the fill material and texture, there is still little consensus for choosing the shape of an implant. Surveys indicate that many surgeons choose only one implant shape, for reasons that may not always agree with outcomes from long-term studies. Objectives: We reviewed the first author's experience over the last six years with both round and anatomical implants, compared the rate of complications with either implant shape, and discussed the importance of keeping an open mind about using both implant shapes for primary breast augmentation...

Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare peripheral T cell lymphoma. BIA-ALCL is a disease of the fibrous capsule surrounding the implant and occurs in patients after both breast reconstruction and augmentation. More than 300 cases have been reported so far, including two in a transgender patient. Here we describe BIA-ALCL presented with a mass in a transgender patient and the first case of BIA-ALCL in the Czech Republic. In 2007, a 33-year-old transgender male to female underwent bilateral breast augmentation as a part of his transformation to female...

We describe an assembly-disposable microfluidic device based on a silicone-coated release polymer thin film. It consists of a disposable polymeric superstrate and a reusable functional substrate and they are assembled simply using vacuum pressure. The disposable polymeric superstrate is manufactured by bonding a silicone-coated release polymer thin film and a microstructured polydimethylsiloxane (PDMS) replica, containing only a simple structured microchannel. The reusable functional substrate generates an intricate energy field that can penetrate the micrometer-thick polymer film into the microchannel and control microfluids...

Generally, the main complications of silicone implantation are local symptoms. However, some patients develop late-onset systemic symptoms often associated with a rare form of hyperactive immune response, as part of a syndrome known as autoimmune syndrome induced by adjuvants (ASIA). Reported cases of ASIA have shown resolution with explantation, but not with immunomodulatory therapy. In this report, we described a case of a previously healthy 23-year-old woman, who has undergone silicone breast implant augmentation, for aesthetic reasons, and developed localized cutaneous impairment 3 years postsurgery...

Connective tissue diseases associated with silicone breast implants have been widely discussed. In the last decade, siliconosis has been included in the autoimmune/inflammatory syndrome induced by adjuvants (ASIA) next to Gulf War syndrome, macrophage myofascitis and postvaccination phenomena. The ASIA syndrome may appear as lupus, rheumatoid arthritis, or more rarely, as adult Still's disease. We discuss the case of a patient with prolonged fever and clinical criteria for ASIA and Still's disease. The prostheses were resected and pathology showed absence of breast implant associated anaplastic lymphoma ALK (-)...

The surgical removal of a breast tumour is often followed by postoperative irradiation of the surrounding tissue with a radioactive source (brachytherapy). When performing the MammoSite procedure, a spherical silicone balloon is inserted and filled with a NaCl solution. In a period of about five days in several sessions an iridium-192 source with high activity travels through a catheter into the balloon (afterloading) to irradiate the tumour cells remaining in the cavity. In this study, dose distributions of a MammoSite applicator are investigated based on measurements with a 2D detector array, Monte Carlo simulations and calculations with BrachyVision...

Membrane proteins govern many important functions in cells via dynamic oligomerization into active complexes. However, analytical methods to study their distribution and functional state in relation to the cellular structure are currently limited. Here, we introduce a technique for studying single-membrane proteins within their native context of the intact plasma membrane. SKBR3 breast cancer cells were grown on silicon microchips with thin silicon nitride windows. The cells were fixed, and the epidermal growth factor receptor ErbB2 was specifically labeled with quantum dot (QD) nanoparticles...

Clinical breast examination (CBE) is traditionally taught to third-year medical students using a lecture and a tabletop breast model. The opportunity to clinically practice CBE depends on patient availability and willingness to be examined by students, especially in culturally sensitive environments. We propose the use of a hybrid simulation model consisting of a standardized patient (SP) wearing a silicone breast simulator jacket and hypothesize that this, compared to traditional teaching methods, would result in improved learning...

BACKGROUND: Implant-based breast reconstruction is the most common type of reconstruction after postmastectomy radiation therapy (PMRT). The impact of the timing of PMRT to a tissue expander or permanent implant is not well understood. The purpose of this systematic review was to evaluate outcomes in implant-based reconstruction and the timing of PMRT. METHODS: A review of the English literature in the PubMed/MEDLINE database (2000-2016) was performed to identify all articles on implant-based breast reconstruction and PMRT...
