Abstract
미용적 성형 및 유방암 수술 후 재건의 목적으로 사용되는 실리콘 보형물의 사용이 국내외에서 크게 증가함에 따라 진료 영역에서 실리콘 보형물 삽입술을 받은 환자들을 어렵지 않게 접하게 되었다. 기존에 알려져 있던 보형물의 파열이나 구축과 같은 합병증 외에 최근에는 유방 보형물 연관 역형성 대세포 림프종과 같은 악성 종양과의 연관성도 보고되면서 보형물 관련한 영상 검사가 증가하고 있다. 이러한 상황에서 영상의학과 의사들은 보형물 삽입술을 받은 환자에 대해 어떤 검사가 필요하고 어떤 영상 소견이 보형물 관련 합병증을 시사하는지에 관한 충분한 지식을 갖추고 있어야 할 것이다. 본 종설에서는 영상의학과 의사들이 알아야 하는 실리콘 보형물의 다양한 합병증과 이들의 영상 소견에 대해 다루고자 한다.

Etiology of Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL): Current Directions in Research. Cancers (Basel) 2020; 12:cancers12123861. [PMID: 33371292 PMCID: PMC7765924 DOI: 10.3390/cancers12123861] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Accepted: 12/16/2020] [Indexed: 02/07/2023] Open
Abstract
Simple Summary The first report of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) was in 1997. Although BIA-ALCL develops around breast implants, it is considered a cancer of the immune system and not a cancer of the breast ducts or lobules. Nearly all confirmed cases to date have been associated with textured surface (versus smooth surface) breast implants. As physicians have become more aware of BIA-ALCL, so has the number of reported cases, although the number of cases remains low. In most instances, patients have an excellent prognosis following removal of the breast implant and its surrounding fibrous capsule. Many theories on factors that trigger the development of BIA-ALCL, such as the presence of bacteria, have been proposed. However, the sequence(s) of events that follow the initial triggering event(s) have not been fully determined. This article summarizes the current scientific knowledge on the development of BIA-ALCL. Abstract Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a CD30-positive, anaplastic lymphoma kinase-negative T-cell lymphoma. Where implant history is known, all confirmed cases to date have occurred in patients with exposure to textured implants. There is a spectrum of disease presentation, with the most common occurring as a seroma with an indolent course. A less common presentation occurs as locally advanced or, rarely, as metastatic disease. Here we review the immunological characteristics of BIA-ALCL and potential triggers leading to its development. BIA-ALCL occurs in an inflammatory microenvironment with significant lymphocyte and plasma cell infiltration and a prominent Th1/Th17 phenotype in advanced disease. Genetic lesions affecting the JAK/STAT signaling pathway are commonly present. Proposed triggers for the development of malignancy include mechanical friction, silicone implant shell particulates, silicone leachables, and bacteria. Of these, the bacterial hypothesis has received significant attention, supported by a plausible biologic model. In this model, bacteria form an adherent biofilm in the favorable environment of the textured implant surface, producing a bacterial load that elicits a chronic inflammatory response. Bacterial antigens, primarily of Gram-negative origin, may trigger innate immunity and induce T-cell proliferation with subsequent malignant transformation in genetically susceptible individuals. Although much remains to be elucidated regarding the multifactorial origins of BIA-ALCL, future research should focus on prevention and treatment strategies, recognizing susceptible populations, and whether decreasing the risk of BIA-ALCL is possible.

Abstract
Breast implant-associated anaplastic large T-cell lymphoma (BIA-ALCL) was first recognized by the World Health Organization in 2016. The total number of cases worldwide continues to increase, with >800 cases confirmed through a combination of Food and Drug Administration data, verified reports, and registries. To date, 33 deaths have been reported. Typical presentation includes a late seroma containing monoclonal T cells that are CD30 positive and anaplastic lymphoma kinase negative. We present a review of the current literature and report on 3 cases of BIA-ALCL at our institution, which serve to illustrate our approach to diagnosis and management of this disease. In 2 cases, the diagnosis of BIA-ALCL was not initially confirmed due to an incomplete workup but was recognized upon explantation. The seroma fluid was sent for flow cytometry. Initially, the cells were reported as morphologically suspicious for malignancy with phenotypically normal T cells based on standard CD3+ T-cell gating. Subsequent cytology specimens were reported as consistent with recurrent adenocarcinoma. However, upon regating of flow-cytometry data, a population of CD30+, CD3- T cells was noted and the diagnosis of BIA-ALCL was confirmed by immunohistochemical stains of the excised breast capsule specimen. Given the increasing incidence of this disease, as plastic surgeons we must stay informed to order the correct workup to avoid misdiagnosis and be prepared to appropriately refer affected patients to centers with multidisciplinary teams experienced in the management of BIA-ALCL.

Abstract
Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a complex topic with evolving classification and etiology. Commonalities between BIA-ALCL and lymphoproliferative disorders exist, suggesting that BIA-ALCL may be better represented on a spectrum of disease from benign effusion to malignant metastatic lymphoma. Meticulous sterile surgical technique, involving the use of betadine-containing irrigation, should be used to decrease the biological burden introduced into the surgical field and possibly prevent future incidences of BIA-ALCL.

Abstract
BACKGROUND Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an emerging cancer that has been linked to the use of textured devices. The recent increase in number and frequency of cases has led to worldwide regulatory action. OBJECTIVES The authors aimed to longitudinally study BIA-ALCL in Australia since the index case was first reported in 2007. METHODS Confirmed historical cases were collected and then prospectively analyzed from October 2015 to May 2019. Clinical and implant exposure data were determined and compared with company sales data for 4 devices to generate implant-specific risk. RESULTS A total 104 cases of BIA-ALCL were diagnosed in Australia with exposure to 149 unique breast implants. The mean age of patients was 48.2 years (range, 22.4-78.5 years). They had an average time from implantation to diagnosis of 6.8 years. A total 51.7% of implants utilized in this cohort were Allergan Biocell devices. The indication for implant usage was for primary cosmetic augmentation in 70%, post-breast cancer reconstruction in 23%, and following weight loss/pregnancy in 7%. The majority of women presented with early (stage 1) disease (87.5%). The risk for developing BIA-ALCL ranged from 1 in 1947 sales (95% confidence interval = 1199-3406) for Silimed Polyurethane devices to 1 in 36,730 (95% confidence interval = 12,568-178,107) for Siltex imprinted textured devices. CONCLUSIONS Implants with higher surface area/texture seem to be more associated with BIA-ALCL in Australia. Recent regulatory action to suspend, cancel, or recall some of these higher risk devices is supported by these findings. LEVEL OF EVIDENCE: 2

Abstract
BACKGROUND Specific antimicrobial breast pocket irrigations have been proven over the past 20 years to reduce the incidence of capsular contracture by a factor of 10, and the emergence of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) and its link to bacteria/technique has created renewed interest in different antimicrobial breast pocket preparation agents. Our previous studies have identified that both Betadine-containing and non-Betadine-containing antimicrobial irrigations provide excellent broad-spectrum bacterial coverage. The current science of BIA-ALCL has implicated the Gram-negative microbiome as a key in pathogenesis. OBJECTIVES The aim of this study was to revisit the antimicrobial effectiveness of clinically utilized Betadine and non-Betadine solutions, along with other antimicrobial agents that have not yet been tested, against multiple organisms, including additional common Gram-negative bacteria associated with chronic breast implant infections/inflammation. METHODS Current and new antimicrobial breast irrigations were tested via standard techniques for bactericidal activity against multiple Gram-positive and Gram-negative strains. Test results are detailed and clinical recommendations for current antimicrobial irrigations are provided. RESULTS Betadine-containing irrigations were found to be superior according to the testing performed. CONCLUSIONS There are quite few misconceptions with regard to antimicrobial breast pocket irrigation. These are discussed and final evidence-based recommendations for practice are given.

Abstract
BACKGROUND Previous studies have reported decreased rates of capsular contracture associated with the use of textured surface breast implants placed in the subglandular plane during breast augmentation. However, since the publication of these studies, our understanding of the pathophysiology of capsular contracture, as well as the surgical techniques utilized to minimize bacterial contamination of the implant, have advanced considerably. OBJECTIVES The purpose of this study was to re-evaluate the relation between implant surface texturization and capsular contracture rates for breast implants placed in the subglandular plane during primary breast augmentation. METHODS Retrospective chart review was performed of all primary subglandular breast augmentation procedures involving the use of either smooth or textured round silicone gel implants, with or without simultaneous mastopexy. The primary outcome measures included clinically significant capsular contracture (Baker grade III/IV) and revision surgery for capsular contracture. RESULTS Between 2010 and 2017, 526 patients underwent primary subglandular breast augmentation with either smooth (n = 212) or textured (n = 314) round silicone gel implants; 248 patients underwent breast augmentation, whereas 278 underwent breast augmentation-mastopexy. Average follow-up was 756 days in the textured group and 461 days in the smooth group. Five cases of capsular contracture were observed in the textured group, and 7 cases of capsular contracture were observed in the smooth group (P = 0.20). CONCLUSIONS Smooth surface implants placed in the subglandular plane were not at a significantly increased risk of capsular contracture compared with textured surface implants. We suggest that adherence to a surgical technique focused on minimizing bacterial contamination of the implant is of greater clinical significance than implant surface characteristics when discussing capsular contracture.

Abstract
BACKGROUND Staphylococcus epidermidis and Pseudomonas aeruginosa are the most common causes of Gram-positive and Gram-negative breast implant-associated infection. Little is known about how these bacteria infect breast implants as a function of implant surface characteristics and timing of infection. OBJECTIVES The aim of this work was to establish a mouse model for studying the impact of various conditions on breast implant infection. METHODS Ninety-one mice were implanted with 273 breast implant shells and infected with S. epidermidis or P. aeruginosa. Smooth, microtextured, and macrotextured breast implant shells were implanted in each mouse. Bacterial inoculation occurred during implantation or 1 day later. Implants were retrieved 1 or 7 days later. Explanted breast implant shells were sonicated, cultured, and colony-forming units determined or analyzed with scanning electron microscopy. RESULTS P. aeruginosa could be detected on all device surfaces at 1- and 7- days post infection (dpi), when mice were implanted and infected concurrently or when they were infected 1- day after implantation. However, P. aeruginosa infection was more robust on implant shells retrieved at 7 dpi and particularly on the macrotextured devices that were infected 1 day post implantation. S. epidermidis was mostly cleared from implants when mice were infected and implanted concurrently. Other the other hand, S. epidermidis could be detected on all device surfaces at 1 dpi and 2 days post implantation. However, S. epidermdis infection was suppressed by 7 dpi and 8 days post implantation. CONCLUSIONS S. epidermidis required higher inoculating doses to cause infection and was cleared within 7 days. P. aeruginosa infected at lower inoculating doses, with robust biofilms noted 7 days later.

Abstract
The choice between anatomical and round implants is an important decision in breast augmentation surgery; however, both have their place and the decision between them that should be made on a patient-by-patient basis, taking into account the patient's desires, anatomy, and surgical history. In some individuals, there are clear indications for using either anatomical or round devices, and there is good evidence that aesthetic outcomes are better with anatomical implants in some instances. When both types are an option, anatomical devices may offer increased flexibility and, despite a longer learning curve needed to properly manage them, they are associated with positive long-term outcomes and high levels of patient satisfaction. Concerns about implant rotation can be minimized with proper patient selection and surgical technique, and the overall complication rate may favor anatomical over round devices in appropriate patients. Breast implant-associated anaplastic large-cell lymphoma is an important issue, and while rare, it must be considered in the context of the entire patient risk profile. Both anatomical and round implants remain key elements of a complete surgical toolbox in breast augmentation.

Abstract
BACKGROUND Staphylococcus epidermidis is a primary cause of breast implant-associated infection. S epidermidis possesses several virulence factors that enable it to bind both abiotic surfaces and host factors to form a biofilm. In addition S epidermidis colocalizes with matrix proteins coating explanted human breast implants. OBJECTIVES The authors sought to identify matrix proteins that S epidermidis may exploit to infect various breast implant surfaces in vitro. METHODS A combination of in vitro assays was used to characterize S epidermidis strains isolated from human breast implants to gain a better understanding of how these bacteria colonize breast implant surfaces. These included determining the (1) minimum inhibitory and bactericidal concentrations for irrigation solutions commonly used to prevent breast implant contamination; (2) expression and carriage of polysaccharide intercellular adhesin and serine-aspartate repeat proteins, which bind fibrinogen (SdrG) and collagen (SdrF), respectively; and (3) biofilm formation on varying implant surface characteristics, in different growth media, and supplemented with fibrinogen and Types I and III collagen. Scanning electron microscopy and immunofluorescence staining analyses were performed to corroborate findings from these assays. RESULTS Textured breast implant surfaces support greater bacterial biofilm formation at baseline, and the addition of collagen significantly increases biomass on all surfaces tested. We found that S epidermidis isolated from breast implants all encoded SdrF. Consistent with this finding, these strains had a clear affinity for Type I collagen, forming dense, highly structured biofilms in its presence. CONCLUSIONS The authors found that S epidermidis may utilize SdrF to interact with Type I collagen to form biofilm on breast implant surfaces. LEVEL OF EVIDENCE: 5

Abstract
BACKGROUND Implementation of polyurethane-covered (PU) implants into practice requires a reassessment of the experience and a learning curve period. Occasional publications describe a few difficulties in this regard. However, there are no publications covering the spectrum of errors. The absence of definite information and contradictory findings makes the learning curve longer leading to many unsatisfactory results. MATERIALS AND METHODS The systematization is based on the 12 years of experience with over 1000 patients and previously published data. A literature review was conducted using PUBMED with the following keywords: polyurethane or foam or sponge and breast and implant. A total of 285 articles were found (last accessed 08/13/2019). All articles concerning polyurethane implants were studied along with any articles found describing the surgical techniques applied to them. Additional references found in the above-mentioned articles were also included in the study. RESULTS All errors can be divided into planning errors, errors in pocket development and surface-dependent errors, for which the polyurethane surface is the main reason. Surface-dependent errors include the errors connected to positioning and biointegration. The possible causes of late seroma with PU implants are discussed. CONCLUSIONS The polyurethane surface should not be considered textured in the clinical point of view. Previous experience with non-PU implants cannot be transferred to PU implants. The learning curve is unavoidable. The systematization of errors with PU implants facilitates a decision-making process during the primary and secondary surgery and lowers the risk of the unsatisfactory results.

Abstract
Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a recently recognized non-Hodgkin lymphoma of T-cell origin. Despite the low incidence of this new disease, the increasing use of breast implants for cosmetic or post-mastectomy reconstruction purposes places BIA-ALC as an emerging and compelling medical challenge. The real BIA-ALCL pathogenesis has not been fully uncovered so far, while different putative causal factors have been proposed. Breast implants with textured surfaces seem to be associated with nearly all cases of BIA-ALCL, while the real the risk of disease development has not been well estimated so far. Late onset, persistent seroma around breast implant represents the classical clinical presentation. Most of the BIA-ALCL patients presents with localized disease, which confers an excellent prognosis. Unlike other non-Hodgkin lymphomas, surgical excision of the mass has a key role in the treatment. For patients with advanced and disseminated diseases, the treatment did not differ from other types of T-cell lymphoma. For these reasons, BIA-ALCL represents an emerging disease which requires multidisciplinary team approach to well define diagnostic workup and treatment for each patient. This review article aims to summarize available data on BIA-ALCL. First, we will outline available data on BIA-ALCL epidemiology, pathogenesis, diagnostic work-up, and treatment. Second, we will point out the potential psychological implications as well as the risk of perception distortion for women with breast implants, especially for those with previous breast cancer. Lastly, we will summarize the current national recommendations regarding textured breast implants and discuss the diagnostic-therapeutic algorithm for BIA-ALCL management.

Abstract
BACKGROUND Traditional 2-stage breast reconstruction involves placement of a textured-surface tissue expander (TTE). Recent studies have demonstrated textured surface devices have higher propensity for bacterial contamination and biofilm formation. OBJECTIVES The purpose of this study was to evaluate the safety and efficacy of smooth surface tissue expanders (STE) in immediate breast reconstruction. METHODS The authors retrospectively reviewed consecutive women who underwent STE breast reconstruction from 2016 to 2017 at 3 institutions. Indications and outcomes were evaluated. RESULTS A total 112 patients underwent STE reconstruction (75 subpectoral, 37 prepectoral placement), receiving 173 devices and monitored for a mean follow-up of 14.1 months. Demographics of patients included average age of 53 years and average BMI of 27.2 kg/m2, and 18.6% received postmastectomy radiation therapy. Overall complication rates were 15.6% and included mastectomy skin flap necrosis (10.4%), seroma (5.2%), expander malposition (2.9%), and infection requiring intravenous antibiotic therapy (3.5%). Six (3.5%) unplanned reoperations with explantation were reported for 3 infections and 3 patients requesting change of plan with no reconstruction. CONCLUSIONS STEs represent a safe and efficacious alternative to TTE breast reconstruction with at least equitable outcomes. Technique modification including tab fixation, strict pocket control, postoperative bra support, and suture choice may contribute to observed favorable outcomes and are reviewed. Early results for infection control and explantation rate are encouraging and warrant comparative evaluation for potential superiority over TTEs in a prospective randomized trial.

Abstract
BACKGROUND The objective of this clinical review is to provide an overview of the use of silicone gel-filled breast implants placed in the sub-muscular position, with a focus on complication rates reported for both smooth and textured implants. Furthermore, our experience in this field is also reviewed. METHODS MEDLINE, EMBASE, Web of Science, Scopus, the Cochrane Central and Google Scholar databases were reviewed to identify the literature related to smooth breast implants. Each article was reviewed by two independent reviewers to ensure all relevant publications were identified. The literature search identified 98 applicable articles. Of these, just a few articles were found to have a therapeutic level of evidence. The reference lists in each relevant paper were screened manually to include relevant papers not found through the initial search. RESULTS Eight articles report the risk of capsular contracture when the breast implants were placed in the sub-muscular position. Six of these articles report a similar rate of capsular contracture in smooth and textured implants. Local complications such as wrinkling, late seroma and double capsules were found to be associated with the use of textured breast implants (4 articles). All articles concerning BIA-ALCL reported a total absence occurring in smooth breast implants. All cases have been associated with textured mammary prostheses. CONCLUSION With our expertise in the field and the results of this up-to-date literature review, it can be concluded that there are no significant advantages of using one type of implant surface over the other when placed in the sub-pectoral position.

Abstract
Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is an emerging and indolent, but potentially fatal cancer of the immune system that can develop around textured-surface breast implants. The World Health Organization first recognized BIA-ALCL as a unique clinical entity in 2016. To date, over 600 confirmed cases have been reported worldwide. BIA-ALCL most commonly presents with disease confined to the capsule, as a seroma or a mass adjacent to the implant. While BIA-ALCL has a fairly indolent clinical course, with an excellent prognosis in early stage disease, disseminated cancer and death have also been reported. In this review, the authors focus on the early diagnosis and treatment, including reconstructing the breast following BIA-ALCL, and also discuss recently updated National Comprehensive Cancer Network guidelines. They also review the current epidemiology and risk factors associated with BIA-ALCL. Finally, they discuss important medicolegal considerations and the bioethics surrounding the continued use of textured-surface breast implants.

Cell of Origin and Immunologic Events in the Pathogenesis of Breast Implant-Associated Anaplastic Large-Cell Lymphoma. THE AMERICAN JOURNAL OF PATHOLOGY 2019; 190:2-10.

Abstract
Breast implant–associated anaplastic large-cell lymphoma (BIA-ALCL) is a CD30-positive, anaplastic lymphoma kinase–negative T-cell lymphoma. Nearly all cases have been associated with textured implants. Most cases are of effusion-limited, indolent disease, with an excellent prognosis after implant and capsule removal. However, capsular invasion and tumor mass have a more aggressive course and a fatal outcome risk. This review summarizes the current knowledge on BIA-ALCL cell of origin and immunologic factors underlying its pathogenesis. Cytokine expression profiling of BIA-ALCL cell lines and clinical specimens reveals a predominantly type 17 helper T-cell (Th17)/Th1 signature, implicating this as its cell of origin. However, a Th2 allergic inflammatory response is suggested by the presence of IL-13, with infiltration of eosinophils and IgE-coated mast cells in clinical specimens of BIA-ALCL. The microenvironment-induced T-cell plasticity, a factor increasingly appreciated, may partially explain these divergent results. Mutations resulting in constitutive Janus kinase (JAK)–STAT activation have been detected and associated with BIA-ALCL pathogenesis in a small number of cases. One possible scenario is that an inflammatory microenvironment stimulates an immune response, followed by polyclonal expansion of Th17/Th1 cell subsets with release of inflammatory cytokines and chemokines and accumulation of seroma. JAK-STAT3 gain-of-function mutations within this pathway and others may subsequently lead to monoclonal T-cell proliferation and clinical BIA-ALCL. Current research suggests that therapies targeting JAK proteins warrant investigation in BIA-ALCL.

Abstract
The authors describe their surgical technique for single-stage periareolar mastopexy with subglandular breast augmentation. They have performed this procedure in 85 patients since 2009 and found that this operative technique has allowed them to achieve reproducible outcomes in a single-stage procedure. Periareolar mastopexy with subglandular breast augmentation is an excellent procedure for patients who desire a larger breast size and who present with mild to moderate nipple ptosis with a paucity of excess skin in the lower pole of the breast. This article will review the perioperative management and detailed steps of the procedure and outline its indications for utilization and some of the common complications the authors have encountered.

Abstract
Though rare, breast implant-associated anaplastic large cell lymphoma (BIA-ALCL), a CD30+ T-cell lymphoma associated with textured breast implants, has adversely impacted our perception of the safety of breast implants. Its etiology unknown, one hypothesis suggests an initiating inflammatory stimulus, possibly infectious, triggers BIA-ALCL. We analyzed microbiota of breast, skin, implant and capsule in BIA-ALCL patients (n = 7), and controls via culturing methods, 16S rRNA microbiome sequencing, and immunohistochemistry. Alpha and beta diversity metrics and relative abundance of Gram-negative bacteria were calculated, and phylogenetic trees constructed. Staphylococcus spp., the most commonly cultured microbes, were identified in both the BIA-ALCL and contralateral control breast. The diversity of bacterial microbiota did not differ significantly between BIA-ALCL and controls for any material analyzed. Further, there were no significant differences in the relative abundance of Gram-negative bacteria between BIA-ALCL and control specimens. Heat maps suggested substantial diversity in the composition of the bacterial microbiota of the skin, breast, implant and capsule between patients with no clear trend to distinguish BIA-ALCL from controls. While we identified no consistent differences between patients with BIA-ALCL-affected and contralateral control breasts, this study provides insights into the composition of the breast microbiota in this population.

Abstract
BACKGROUND Capsular contracture (CC) has remained an unresolved issue throughout history. Strong evidence focuses on bacterial biofilm as its main source. A literature review revealed that more than 90% of bacteria found in capsules and implants removed from patients with Baker grade III-IV CC belong to the resident skin microbiome (Staphylococcus epidermidis, predominant microorganism). The use of an adequate preoperative skin antiseptic may be a critical step to minimize implant contamination and help prevent biofilm-related CC. OBJECTIVES The authors sought to compare the effect of 2 different antiseptic skin preparations: povidone-iodine (PVP-I) vs chlorhexidine gluconate (CHG) on CC proportions after primary breast augmentation through a periareolar approach. METHODS In June of 2014, The Society for Healthcare Epidemiology of America proposed to use CHG for preoperative skin preparation in the absence of alcohol-containing antiseptic agents as strategy to prevent surgical site infection. The clinical safety committee of a surgical center in Colombia decided to change PVP-I to CHG for surgical site preparation thereafter. The medical records of 63 patients who underwent to primary breast augmentation through a periareolar approach during 2014 were reviewed. In the first 6 months PVP-I was used in 32 patients, and later CHG was employed in 31 patients. RESULTS Pearson's chi-squared test to compare CC proportions between subgroups showed a statistically significant difference. The CC proportion was higher for patients who had antisepsis with PVP-I. CC was absent when CHG was employed. CONCLUSIONS CHG as preoperative skin antiseptic for primary breast augmentation surgery was more effective than PVP-I to help prevent biofilm-related CC.

Abstract
BACKGROUND The epidemiology and implant-specific risk for breast implant-associated (BIA) anaplastic large cell lymphoma (ALCL) has been previously reported for Australia and New Zealand. The authors now present updated data and risk assessment since their last report. METHODS New cases in Australia and New Zealand were identified and analyzed. Updated sales data from three leading breast implant manufacturers (i.e., Mentor, Allergan, and Silimed) were secured to estimate implant-specific risk. RESULTS A total of 26 new cases of BIA-ALCL were diagnosed between January of 2017 and April of 2018, increasing the total number of confirmed cases in Australia and New Zealand to 81. This represents a 47 percent increase in the number of reported cases over this period. The mean age and time to development remain unchanged. The implant-specific risk has increased for Silimed polyurethane (23.4 times higher) compared with Biocell, which has remained relatively static (16.5 times higher) compared with Siltex implants. CONCLUSIONS The number of confirmed cases of BIA-ALCL in Australia and New Zealand continues to rise. The implant-specific risk has now changed to reflect a strong link to implant surface area/roughness as a major association with this cancer.

Abstract
The Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL) represents a topic of great concern. We report the case of a patient with late-onset seroma, who was initially diagnosed with an implant-related infection of the breast due to microbial detection in the seroma fluid, thus delaying the diagnosis of BIA-ALCL.

Abstract
Background Bacterial biofilms have been implicated with breast implant complications including capsular contracture and anaplastic large-cell lymphoma. The actual mechanisms for either are still under active investigation and are not clear. Due to their increased surface area, implants with textured surfaces may harbor greater biofilm loads than those with smooth surfaces. Methods Biofilm formation on the outer surface material was compared using implants with various surface areas and roughness, including Natrelle® (Smooth), SmoothSilk®/SilkSurface® (Silk), VelvetSurface ® (Velvet), Siltex®, and Biocell®. The roughness and surface area of each material were assessed using non-contact profilometry. Bacterial attachment (2 h) and biofilm formation (24 h) were evaluated for Staphylococcus epidermidis, Pseudomonas aeruginosa, and Ralstonia pickettii over nine independent experiments using a CDC biofilm reactor and viable plate counts (VPCs) as well as confocal scanning laser microscopy. VPCs of the textured implants were compared relative to the Smooth implant. Results Surface areas increased with roughness and were similar among the three least rough implants (Smooth, Silk, and Velvet) and among the roughest implants (Siltex and Biocell). Overall, VPC indicated there was significantly more bacterial attachment and biofilm formation on the Siltex and Biocell implants than the Silk or Velvet implants, although there were differences between species and time points. CSLM confirmed the formation of thicker biofilms on the implants with rougher surface textures. Conclusion This in vitro study confirmed that implant surfaces with rougher texture, resulting in more surface area, harbored greater biofilm loads than those with smoother surfaces.

Abstract
LEARNING OBJECTIVES After reading this article, the participant should be able to: 1. Develop a practical method for preoperative implant size selection. 2. List characteristics and examples of fourth- and fifth-generation silicone implants. 3. Recognize the differences in "profile" designations across implant manufacturers. 4. Recall updated statistics on breast implant-associated anaplastic large cell lymphoma and describe current guidelines on disease diagnosis and treatment. 5. Apply atraumatic and aseptic surgical techniques in primary breast augmentation. SUMMARY Modern primary breast augmentation requires an intimate knowledge of the expanding breast implant market, including characteristics of current generation silicone implants and "profile" types. Optimal implant size selection requires balancing patient desires with tissue qualities. Evidence and awareness of breast implant-associated anaplastic large cell lymphoma continue to grow, and patients and surgeons alike should be informed on the most updated facts of the disease entity. Atraumatic surgical technique and aseptic adjuncts are critical in reducing periprosthetic inflammation and contamination, both of which are known instigators of capsular contracture and potentially breast implant-associated anaplastic large cell lymphoma.

Abstract
LEARNING OBJECTIVES After reviewing the article, the participant should be able to: 1. Understand the tenets of proper patient selection. 2. Be familiar with the assessment of patients for augmentation-mastopexy. 3. Be able to plan an operative approach and execute the critical steps. 4. Be able to recognize common complications and have a basic understanding of their management. 5. Be aware of emerging adjunctive techniques and technologies with respect to augmentation-mastopexy. SUMMARY Despite being a multivariable and complex procedure, augmentation-mastopexy remains a central and pivotal component of the treatment algorithm for ptotic and deflated breasts among plastic surgeons. Careful preoperative planning, combined with proper selection of approach and implant, can lead to success. Physicians need to understand that there is a high frequency of reoperation cited in the literature with regard to this procedure, and discussions before the initial operation can help alleviate common misunderstandings and challenges inherent in this operation.

Abstract
The most common malignancy in women, breast cancer remains a major medical challenge that affects the life of thousands of patients every year. With recognized benefits to body image and self-esteem, the use of synthetic mammary implants for elective cosmetic augmentation and post-mastectomy reconstruction continues to increase. Higher breast implant use leads to an increased occurrence of implant-related complications associated with implant leakage and rupture, capsular contracture, necrosis and infections, which include delayed healing, pain, poor aesthetic outcomes and the need for revision surgeries. Along with the health status of the implant recipient and the skill of the surgeon, the properties of the implant determine the likelihood of implant-related complications and, in doing so, specific patient outcomes. This paper will review the challenges associated with the use of silicone, saline and "gummy bear" implants in view of their application in patients recovering from breast cancer-related mastectomy, and investigate the opportunities presented by advanced functional nanomaterials in meeting these challenges and potentially opening new dimensions for breast reconstruction. STATEMENT OF SIGNIFICANCE: Breast cancer is a significant cause of morbidity and mortality in women worldwide, which is difficult to prevent or predict, and its treatment carries long-term physiological and psychological consequences. Post-mastectomy breast reconstruction addresses the cosmetic aspect of cancer treatment. Yet, drawbacks of current implants contribute to the development of implant-associated complications, which may lead to prolonged patient care, pain and loss of function. Nanomaterials can help resolve the intrinsic biomechanical mismatch between implant and tissues, enhance mechanical properties of soft implantable materials, and provide an alternative avenue for controlled drug delivery. Here, we explore advances in the use of functionalized nanomaterials to enhance the properties of breast implants, with representative examples that highlight the utility of nanomaterials in addressing key challenges associated with breast reconstruction.

The Detection of Bacteria and Matrix Proteins on Clinically Benign and Pathologic Implants. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2019; 7:e2037. [PMID: 30881821 PMCID: PMC6416121 DOI: 10.1097/gox.0000000000002037] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2018] [Accepted: 09/26/2018] [Indexed: 01/24/2023]
Abstract
Supplemental Digital Content is available in the text. Background: Bacterial contamination of breast implants causes infection, can lead to capsular contracture, and is implicated in breast implant-associated anaplastic large cell lymphoma. Bacteria, however, also colonize clinically benign breast implants and little is known about the biologic signals that trigger the switch from a benign to pathologic state. Methods: Explanted smooth as well as Biocell and Siltex textured breast implants associated with clinically normal and pathologic conditions were analyzed in this observational study. Immunofluorescence and bacterial culture techniques were performed. To avoid sampling bias, implant surfaces >25 sq cm were analyzed. Results: Bacteria were detected on 9 of 22 clinically normal explanted devices or periprosthetic capsules, including 40% of Biocell tissue expanders and 75% of Biocell textured implants. Staphylococcus epidermidis was identified in 67% of the bacteria-positive capsular contractures. Fibrinogen was present on 17 of 18, and collagen on 13 of 18 analyzed breast implants. S. epidermidis co-localized with collagen, while group B streptococci and Klebsiella pneumoniae co-localized with fibrinogen. Conclusions: Bacteria are often detectable on clinically benign breast implants when a multimodal approach is applied to a substantial proportion of the device surface to avoid sampling bias. The impact of bacteria on breast implant pathology should be studied in the presence of an adequate negative control group to account for clinically benign bacteria. Disruption of the interaction of bacteria with matrix proteins coating the surface of breast implants may represent a nonantibiotic strategy for the prevention of breast implant bacterial contamination.

Abstract
BACKGROUND One of the undesirable complications that might occur after breast augmentation with silicone implants is capsular contracture. In its etiology, the relations between mast cells and myofibroblasts play an important role in collagen synthesis. Mast cells are able to activate fibroblasts into myofibroblasts, through paracrine secretions, inducing collagen production. The objectives of this study were to analyze the myofibroblast concentration through the α-SMA immunomarker and evaluate the intensity of mast cell expression against the C-Kit immunomarker. MATERIAL AND METHOD Sixty-four Wistar rats were used, divided into two groups (polyurethane foam and textured surface) with 32 animals in each. The animals received silicone implants on the back, below the panniculus carnosus, and after the determined period, they were killed and the capsules formed around the implants were studied. The capsules were analyzed employing the immunohistochemical technique, with the α-SMA and C-Kit immunomarkers in subgroups of 30, 50, 70 and 90 days. RESULTS The myofibroblast concentration was higher in the polyurethane group when compared to the textured group (30 days p = 0.105; 50 days p = 0.247; 70 days p = 0.014 and 90 days p = 0.536). The intensity of mast cell expression was more pronounced in the polyurethane group when compared to the textured group (30 days p = 0.798; 50 days p = 0.537; 70 days p = 0.094 and 90 days p = 0.536). CONCLUSIONS Polyurethane-coated implants induced higher concentrations of myofibroblasts and higher expression of mast cells, when compared to the textured surface implants.

Abstract
Anaplastic large cell lymphoma (ALCL) is a rare form of lymphoma involving cells of the immune system. It is currently gaining interest because of an association between the development of ALCL and an increased risk in women who have had breast implant surgery. Although not confirmed, many theories exist as to the etiology of this association in women, and there is growing concern that ALCL is more prevalent in women with textured breast implants. In particular, the risk of developing ALCL appears to be related to increasing implant texturization or "surface roughness." This paper examines the current manner of defining and characterizing breast implant surface texture and challenges the appropriateness of applying this technology and linking it to ALCL. It is not a comprehensive review of the etiology of capsular contracture and ALCL, but it proposes an alternative perspective on surface texture measurements from that currently employed and its role in researching the etiology of ALCL. The authors hope that their article will provoke thought and reflection when considering the issues currently being highlighted with regard to texturing of breast implants.

The Histological Composition of Capsular Contracture Focussed on the Inner Layer of the Capsule: An Intra-Donor Baker-I Versus Baker-IV Comparison. Aesthetic Plast Surg 2018; 42:1485-1491.

Abstract
Background Capsular contracture remains one of the major complications after breast implantation surgery. The extent of capsular contraction is scored using the Baker scale. The aim of this study was to compare intra-individual Baker-I with Baker-IV capsules, and in particular the prevalence and histological properties of the inner capsule layer. Methods Twenty capsules from ten patients were included after bilateral explantation surgery due to unilateral capsular contracture (Baker-IV) after cosmetic augmentation with textured implants. All capsules underwent (immune-)histochemical analysis: haematoxylin–eosin (morphology), CD68 (macrophages), cytokeratin (epithelial cells) and vimentin (fibroblasts), and were visually scored for cell density and the presence of an inner layer and measured for thickness. Results Baker-IV (n = 10) capsules were significantly thicker compared to Baker-I (n = 10) capsules (P = 0.004). An inner layer was present in 8 Baker-I capsules. All Baker-I capsules were vimentin and CD68-positive and cytokeratin-negative. Positive vimentin was seen throughout the inner layer, and CD-68 staining was observed adjacent to the intermediate capsule layer. In contrast, only 2 Baker-IV capsules had an inner layer, of which only 1 showed the same profile as Baker-I capsules (P = 0.016). No cytokeratin positivity was seen in any capsule. In Baker-IV capsules, outer layers showed more positivity for both vimentin and CD68. Conclusion The inner layer is morphologically consistent with synovial metaplasia and is more prevalent in healthy, uncontracted Baker-I capsules. This inverse relation between the presence of the inner layer and higher Baker classification or pathological contracture could indicate a protective role of the inner layer against capsular contracture formation.

Abstract
Postoperative complications in patients undergoing autologous breast reconstruction should be kept at the lowest possible level. Optimization of autologous breast reconstruction, especially techniques that can identify tissue perfusion and ischemia, will greatly benefit the patients and consequently society. Hence, the aim of this study was to evaluate the complication rates for autologous pedicle flap breast reconstructions, with and without the use of ICG-angiography. A single-institution retrospective review of mastectomy patients was performed. A total of 230 cases who underwent immediate or delayed, unilateral or bilateral pedicle autologous flap breast reconstruction between January 2013 and September 2016 was reviewed. Complication rates in the ICG-angiography and clinical assessment group were evaluated and compared. A total of 191 cases were identified of which 77 were evaluated with ICG-angiography, and 114 were evaluated clinically. There was no significant difference in overall complication rates between the two groups (ICG-angiography, 36.4%; Clinical assessment, 37.7%; p = .88). No significant difference was observed when stratifying for major or minor complications. However, when stratifying for the timing of the reconstruction, the rate of major complications was significantly lower in the ICG-angiography group (ICG-angiography, 0%; Clinical assessment 23.3%; p = .039). BMI was significantly associated with increased risk of minor complications (p = .018), whereas there was no correlation to age, prior smoking, chemotherapy, radiation, diabetes, or hypertension. Our study found that use of ICG-angiography was associated with a significant decrease in the rate of major complications for immediate autologous reconstructions.

Abstract
BACKGROUND Capsular contracture induced by chronic subclinical infection is a major cause of poor outcomes and reoperation in breast implant surgery. The use of pocket irrigation with antiseptic/antibiotic has been shown to reduce the incidence of contracture. A new formulation of hypochlorous acid solution PhaseOne has been proposed as potential agent for irrigation. OBJECTIVES This study aimed to test the efficacy of hypochlorous acid solution PhaseOne for use in breast pocket irrigation as an alternative to povidone iodine solution Betadine. METHODS The efficacy of PhaseOne, a hypochlorous acid formulated wound and skin cleanser, was tested in vitro against planktonic and biofilm Staphylococcus aureus with or without biological soil and in an implant attachment assay. Its activity was compared with Betadine containing 10% povidone iodine. RESULTS Our findings showed that PhaseOne was unable to eradicate planktonic and/or biofilm S. aureus in the presence of either tryptone soy broth or bovine calf serum (protein soil) in a variety of in vitro assays. CONCLUSIONS We advise that povidone iodine containing irrigants are superior to hypochlorous acid containing irrigants in the clinical setting and should remain the recommended solution for pocket irrigation to reduce bacterial contamination at breast implants surgery.
