Abstract
Introduction Breast augmentation, a popular cosmetic surgery using devices like silicone implants, can lead to a common issue called capsular contracture (CC). This condition involves the formation of fibrous tissue around the implants and can be influenced by variables like immunological and bacterial factors. This study aimed to explore the impact of autoimmune diseases (ADs) on CC along with other factors influencing future clinical decisions. Methods A systematic review of electronic databases was conducted using PubMed, Web of Science, Scopus, EMBASE, and involving adult patients (>18) with CC and ADs after breast surgery using MeSH terminology using a broad search strategy. All searches were performed and analyzed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and duplicates were removed with Rayyan. Two independent investigators extracted and assessed the data involving demographics and baseline data related to CC and AD. Results The incidence of CC varied (2.3%-4.1%). Subglandular placement and older device age raised risk. SERI Surgical Scaffold complications included necrosis, seroma, hematoma, implant loss, and infection; CC was associated with necrosis. Natrelle 410 implants showed lower 10-year CC risk than round gel implants. Acellular dermal matrix implant-based breast reconstruction with radiotherapy (RT) correlated with 20.7% post-RT CC. Previous research demonstrated no significant connection between silicone gel implants and ADs. Biofilm, surgical site infection, implant features, and interventions emerged as frequent CC risk factors. Conclusion Finding appropriate techniques to reduce the risk factors associated with CC together with providing comprehensive patient counseling on these factors will definitely improve the patient-centered outcome of breast implant surgery.

Abstract
BACKGROUND About 30% to 50% of women with breast cancer undergo mastectomy, and approximately 50% of them will receive adjuvant radiotherapy (ART). This study evaluates the medium- and long-term impact of ART after immediate breast reconstruction (IBR) with latissimus dorsi myocutaneous (LDM) flap and silicone implants. METHODS Clinical, surgical, and oncological data were retrospectively collected and analyzed based on the medical records of 176 patients who had undergone IBR with LDM flap and silicone implants. RESULTS The data showed that 7.4% of patients had a history of previous radiotherapy, 56.3% received ART, 31.8% developed capsular contracture with a mean follow-up of 58.1 months, and 14.2% of surgeries were categorized as procedures with a prolonged operating time, lasting above 1 SD of the observed mean. Those who experienced prolonged operating time (odds ratio, 4.72; 95% confidence interval, 1.72-12.93; P = 0.003) and those who received ART (odds ratio, 7.38; 95% confidence interval, 3.18-17.10; P < 0.001) were more likely to develop capsular contracture. Thirty-two patients (18%) underwent capsulectomy with implant replacement, and 7 patients (4%) had the implant removed. The mean time between IBR and reoperation was 29.1 months. Patients who received ART were 2.84 times more likely to experience reconstruction failure or undergo implant-related reoperation ( P = 0.002). CONCLUSIONS The results indicated that IBR with LDM flap and silicone implant followed by ART is a safe procedure, resulting in low rates of reconstruction failure. However, ART increased the likelihood of capsular contracture development and implant-related reoperation, having a negative effect on reconstructed breasts.

Abstract
BACKGROUND Capsular contracture is one of the most common complications after breast surgery involving silicone implants. The most likely cause of this condition is biofilm formation. In this study, the efficacy of local antibiotherapy against biofilm formation on implant surfaces was investigated. METHODS Thirty-six rats were divided into six groups. Three pockets were created on the dorsum of each rat, and 1 × 2 cm implant surface samples from smooth, polyurethane and textured implants were randomly placed into pockets. All samples were inoculated with staphylococcus epidermidis. In groups 1-2-3, inoculated samples were placed into the pockets and removed after 1, 6 and 24 h, respectively. In groups 4-5-6, inoculated samples immersed with rifamycin were placed and removed after 1, 6 and 24 h, respectively. Bacterial load was measured with plate count method. RESULTS Bacterial load was lower in groups 4-5-6 than in groups 1-2-3 (p < 0.05). In groups 4-5-6, bacterial load was lower for polyurethane than for textured surfaces at all time points (1, 6 and 24 h; p < 0.05). Again, in groups 4-5-6, bacterial load was lower for smooth than for textured surfaces at 24 h (p < 0.05). In groups 4-5-6, bacterial load was lower for polyurethane than for smooth surfaces at all time points, but difference was not statistically significant (1, 6 and 24 h; p < 0.05). CONCLUSION The results suggest that local antibiotic therapy was effective in reducing the bacterial load on all surfaces. The effectiveness of local rifamycin on the polyurethane surface was higher, and the duration of activity was longer than other surfaces.

Abstract
BACKGROUND Bacterial contamination of implants has been linked to biofilm formation and subsequent infection, capsular contracture, and breast implant-associated anaplastic large cell lymphoma. Reducing contamination during implant insertion should therefore reduce biofilm formation disease sequelae. OBJECTIVES The aim of this study was to compare levels of contamination between preventative techniques. METHODS A model to simulate the passage of implants through a skin incision was designed that utilized a sterile textured polyvinyl plastic sheet contaminated with Staphylococcus epidermidis. In the first stage of the polyvinyl contamination model, implants were subject to infection-mitigation techniques and passed through the incision, then placed onto horse blood agar plates and incubated for 24 hours. In the second stage of the study the same contamination was applied to human abdominal wall specimens. A 5 cm incision was made through skin and fat, then implants were passed through and levels of contamination were measured as described. RESULTS Smooth implants grew a mean of 95 colony-forming units (CFUs; approximately 1 CFU/cm2) and textured implants grew 86 CFUs (also approximately 1 CFU/cm2). CFU counts were analyzed by the Mann-Whitney U-test which showed no significant difference between implant types (P < .05); independent-sample t-tests showed a significant difference. The dependent-variable techniques were then compared as groups by one-way analysis of variance, which also showed a significant reduction compared with the control group (P < .01). CONCLUSIONS This in vitro study has shown the effectiveness of antiseptic rinse and skin/implant barrier techniques for reducing bacterial contamination of breast implants at the time of insertion.

Abstract
Capsular contracture is a prevalent and severe complication that affects the postoperative outcomes of patients who receive silicone breast implants. At present, prosthesis replacement is the major treatment for capsular contracture after both breast augmentation procedures and breast reconstruction following breast cancer surgery. However, the mechanism(s) underlying breast capsular contracture remains unclear. This study aimed to identify the biological features of breast capsular contracture and reveal the potential underlying mechanism using RNA sequencing. Sample tissues from 12 female patients (15 breast capsules) were divided into low capsular contracture (LCC) and high capsular contracture (HCC) groups based on the Baker grades. Subsequently, 41 lipid metabolism-related genes were identified through enrichment analysis, and three of these genes were identified as candidate genes by SVM-RFE and LASSO algorithms. We then compared the proportions of the 22 types of immune cells between the LCC and HCC groups using a CIBERSORT analysis and explored the correlation between the candidate hub features and immune cells. Notably, PRKAR2B was positively correlated with the differentially clustered immune cells, which were M1 macrophages and follicular helper T cells (area under the ROC = 0.786). In addition, the expression of PRKAR2B at the mRNA or protein level was lower in the HCC group than in the LCC group. Potential molecular mechanisms were identified based on the expression levels in the high and low PRKAR2B groups. Our findings indicate that PRKAR2B is a novel diagnostic biomarker for breast capsular contracture and might also influence the grade and progression of capsular contracture.

Abstract
Biomedical implants are crucial in providing support and functionality to patients with missing or defective body parts. However, implants carry an inherent risk of bacterial infections that are biofilm-associated and lead to significant complications. These infections often result in implant failure, requiring replacement by surgical restoration. Given these complications, it is crucial to study the biofilm formation mechanism on various biomedical implants that will help prevent implant failures. Therefore, this comprehensive review explores various types of implants (e.g., dental implant, orthopedic implant, tracheal stent, breast implant, central venous catheter, cochlear implant, urinary catheter, intraocular lens, and heart valve) and medical devices (hemodialyzer and pacemaker) in use. In addition, the mechanism of biofilm formation on those implants, and their pathogenesis were discussed. Furthermore, this article critically reviews various approaches in combating implant-associated infections, with a special emphasis on novel non-antibiotic alternatives to mitigate biofilm infections.

Abstract
Breast implant illness (BII) is a poorly understood disease in which patients develop symptoms typical of autoimmune conditions following breast implantation. There is no known underlying cause, and patients often resort to breast implant removal and capsulectomy to alleviate symptoms. In this issue of the JCI, Khan and colleagues examined 86 breast explants from patients that reported BII symptoms and 55 control explants. The BII group showed a disproportionally high degree of biofilm, which was associated with oxylipin (10-HOME) on the implant surfaces. Injections of 10-HOME in the mammary fat pad of a murine model recapitulated BII symptoms and increased Th1 cell populations. Notably, macrophages in the periprosthetic tissue from BII patients were more likely to exhibit a proinflammatory phenotype, and naive T cells exposed to 10-HOME caused naive macrophages to differentiate to a proinflammatory phenotype. This work provides a pathophysiologic mechanism for a currently understudied and poorly characterized disease.

Abstract
BACKGROUND Rates of capsular contracture have reduced significantly since the use of insertion funnels to place breast implants became routine. However, due to financial constraints, the same funnel is usually used for implantation of both sides. OBJECTIVES The aim of this study was to determine whether the risk of capsular contracture is higher for the second breast when the same insertion funnel is used for both breasts. METHODS The authors collected a sample of the insertion funnel tip immediately after removing the funnel from its sterile packaging and another tip sample after the funnel had been used to insert the first implant. These samples were sent for microbiological culture evaluations. Capsular contracture rates in the first implanted breast vs the second implanted breast were then retrospectively analyzed. RESULTS All samples taken from the funnel before the first implantation showed no bacterial growth. All 10 samples taken from the funnel after the first implantation showed organism growth (8 were positive for Staphylococcus epidermidis and 2 for Cutibacterium acnes). Retrospective analysis of the results revealed that the overall capsular contracture rate had reduced after the authors began to use insertion funnels. However, this complication was still more common on the second implanted breast. CONCLUSIONS Surgeons should consider the use of separate insertion funnels for each breast. This might help to slightly reduce the incidence of capsular contracture.See the abstract translated into Hindi, Portuguese, Korean, German, Italian, Arabic, and Chinese (Simplified and Traditional) online here: https://doi.org/10.1093/asj/sjad288.

Abstract
Capsular contracture (CC) is one of the most common complications of implant-based breast reconstruction or augmentation surgery. Common risk factors of CC include biofilm, surgical site infections, history of prior CC or fibrosis, history of radiation therapy, and implant characteristics. Though bacterial contamination of breast protheses is associated with adverse sequelae, there are not universally accepted guidelines and limited best practice recommendations for antimicrobial breast pocket irrigation. Despite advanced molecular biology, the exact mechanism of this complication is not fully understood. Interventions that decrease the rate of CC include antibiotic prophylaxis or irrigation, acellular dermal matrix, leukotriene inhibitors, surgical techniques, and others. However, there is inconsistent evidence supporting these risk factors, and the current data was based on broad heterogeneous studies. The objective of this review was to provide a summary of the current data of contributing risk factors as well as preventative and treatment measures for CC.Level of Evidence III This journal requires that authors assign a level of evidence to each article.

Abstract
BACKGROUND Broad evidence supports the use of antiseptic pocket rinse in breast implant surgery to minimize the risk of capsular contracture or other complications. However, there is limited consensus or standardization of antiseptic rinse in practice. OBJECTIVES In this preliminary study, we sought to determine contemporary trends in antiseptic rinse use in primary breast implant surgery based on Australian Breast Device Registry (ABDR) data, and whether these trends align with the suggestions of the 14-point plan.2 This further served as a feasibility study for subsequent comparison of antiseptic rinse effects on clinical outcomes. METHODS Institutional ethics approval was obtained and national ABDR data for primary breast implant surgery from 2015-2020 was analysed for the use, and type, of antiseptic rinse. The surgeon-reported data was homogenized for terminology and categorized into major trends, and the literature reviewed. RESULTS We analysed data for 37,143 patients, totalling 73,935 primary implants. Antiseptic rinse included Povidone-Iodine (PVP-I) in 35,859 (48.5%), no antiseptic use in 24,216 (32.8%), other concentrations of PVP-I in 4,200 (5.7%), and 'Betadine® triple antibiotic'1 in 1,831 implants (2.5%). Multiple other antiseptic permutations were noted in 7,004 implants (9.5%). CONCLUSIONS The majority (56.7%) of Australian practitioners utilise previously-described antiseptic pocket irrigation solutions which align with the 14-point plan. A third (32.8%), however, do not record any antiseptic pocket irrigation use. These findings will permit a subsequent (ongoing) study of outcomes comparing PVP-I to no antiseptic pocket rinse that will likely constitute the largest study of its kind.

Abstract
BACKGROUND Capsular contracture is the most common complication following breast implant surgery, and the implant shell characteristics are important in preventing this complication. OBJECTIVES The aim of this study was to evaluate the capsular contracture rate for SmoothSilk Motiva implants (Establishment Labs Holdings Inc., New York, NY) in females who underwent primary and revisional breast augmentation over a 3-year period. METHODS A total of 1324 cases that took place from 2017 to 2020 were retrospectively analyzed, with 1027 being primary surgeries and 297 being revisional surgeries. RESULTS In the 1324 cases of augmentation mammoplasty with SmoothSilk Motiva implants, the overall capsular contracture rate was 1.8% (n = 24). The capsular contracture rate in the 1027 primary surgery cases was 1.07% (n = 11), and the capsular contracture rate in the 297 revisional surgery cases was significantly different at 4.39% (n = 13, P = .0001). More specifically, the capsular contracture rate in 182 revisional surgery for cases without capsular contracture was 1.12% (n = 2), and it showed no statistically significant difference from the rate in primary surgery cases (P = .965). However, the rate in 115 revisional surgery for cases with capsular contracture was 9.57% (n = 11), and it showed a statistically significant difference from the rate in primary surgery cases (P = .000) and the rate in revisional surgery for cases without capsular contracture (P = .001). CONCLUSIONS Augmentation mammoplasty with SmoothSilk Motiva implants demonstrated a lower rate of capsular contracture than traditional smooth or textured implants. Revisional surgery for cases without capsular contracture showed a similar rate of capsular contracture to primary surgery cases, but the rates were higher in revisional surgery for cases with capsular contracture.

Abstract
BACKGROUND Capsular contracture is the most common complication of breast augmentation and reconstruction. It occurs in up to 45% of patients and is theorized to occur secondary to an immune reaction. It can lead to pain, dissatisfaction with aesthetic outcomes, and reoperation. The gold standard for management is capsulectomy. Prior similar studies are limited by narrow inclusion criteria, single-surgeon analysis, small sample size, or univariate analysis. The goal of the following study is to prospectively identify possible risk factors for capsular contracture using a national database. METHODS A retrospective review was conducted utilizing the National Surgical Quality Improvement Program (NSQIP) Database of prospectively collected data of patients undergoing periprosthetic and/or total capsulectomy for capsular contracture from 2013 to 2016. Odds ratios (OR) with 95% confidence intervals (CI) were calculated for variables using a multivariable binary logistic regression model. RESULTS A total of 6547 patients underwent reconstructive or augmentation mammaplasty with a prosthetic implant, out of which 2543 (39%) underwent capsulectomy. Capsular contracture was more likely in older (OR: 1.10, 95% CI: 1.09-1.10, p<.001), overweight (OR: 1.12, 95% CI: 1.10-1.13, p<.001), and cancer patients (OR: 7.71, 95% CI: 2.22-28.8, p=0.001). Wound infection was associated with capsulectomy (OR: 6.69, 95% CI: 1.74-25.8, p<.001). CONCLUSION These identified risk factors should be comprehensively addressed with patients during the informed consent process before breast augmentation or reconstruction with implants.

Comparing the efficacy of antimicrobial pocket-irrigation protocols in an in vivo breast implant infection model. J Plast Reconstr Aesthet Surg 2023; 85:165-173. [PMID: 37499557 DOI: 10.1016/j.bjps.2023.06.062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 06/15/2023] [Accepted: 06/25/2023] [Indexed: 07/29/2023]
Abstract
BACKGROUND Breast implant infection and biofilm formation are major concerns in reconstructive and esthetic breast surgery, with significant medical and economic consequences. Staphylococcus is the common pathogen, with rapidly increasing rates of methicillin-resistant Staphylococcus aureus (MRSA). There is no consensus on prevention practices. This study compares the effect of several pocket irrigation and antibiotic prophylaxis regimens on implant colonization and biofilm formation in an established rat model of MRSA-infected silicone breast implants. METHODS Silicone discs were inserted in a sub-pectoral pocket in 57 rats (114 implants). Implant infection was induced by injection of free planktonic MRSA into the surgical pocket. Rats were allocated to study groups treated by different antimicrobial protocols: pocket irrigation with vancomycin, povidone-iodine, or saline. Each group was divided into subgroups treated with or without additional peri-operative systemic vancomycin. Implant colonization or overt infection was assessed at post-operative day 14 both clinically and by cultures. RESULTS Pocket irrigation with vancomycin prevented contamination in 87% of implants. Irrigation and systemic vancomycin prevented contamination in 100% of implants with no difference between a single preoperative dose and a 48-h regimen. Systemic vancomycin alone or irrigation with povidone-iodine alone resulted in 100% contamination rates. CONCLUSIONS In this in vivo model, combination of systemic vancomycin with vancomycin pocket irrigation was the most effective regimen, preventing contamination in 100% of implants. Continuation of post-operative antibiotic treatment showed no added advantage.

Abstract
BACKGROUND Capsular fibrosis (CF) often occurs around biomedical devices following implantation causing pain, discomfort, and device failure. Breast implantation remains among the most common medical procedures worldwide. Revealing specific genes that drive fibrotic deposition will help us to garner a better understanding of the pathophysiology of this disease and develop different strategies to combat it. METHODS The authors collected 631 capsules around breast implants and were able to connect clinical baseline characteristics with histopathologic findings. In addition, the authors were able to conduct the first large systematic analysis to identify differentially expressed genes in fibrotic human tissue samples, comparing the lowest form of fibrosis with the most aggravated one. RESULTS The authors identified 2559 differentially expressed genes on which they performed a knowledge-based network generation and pathway association study to identify putative novel biomarkers for CF. The authors were able to show changes of cellular influx during progression of CF and distinguish several genes as potential clinical biomarkers and drug targets. Among these, matrix metalloproteinase-9 was one of the most up-regulated ( P = 0.006) and is attractive because of its wide detectability. CONCLUSIONS Matrix metalloproteinase-9 seems to be a potential biomarker to detect capsular fibrosis. It is a measurable indicator that can easily be detected in blood, sputum, and urine. For the diagnosis of fibrosis, this biomarker might be exceedingly beneficial to developing novel screening methods and prophylaxes. CLINICAL RELEVANCE STATEMENT Discovering biomarkers at the earliest and mildest stages for the diagnosis of fibrosis is clinically important. These results bring new hope for biomarker-based diagnosis for capsular fibrosis. CLINICAL QUESTION/LEVEL OF EVIDENCE Diagnostic, V.

Abstract
Background Breast implant surgery is a popular procedure worldwide, and the same holds true for Saudi Arabia. Ensuring a sterile surgical environment is crucial to avert postoperative infections. This study explores the various antiseptic techniques adopted by Saudi plastic surgeons during breast implant procedures. Objectives This study aims to assess Saudi plastic surgeons' adherence to antiseptic measures in breast implant surgery, and determine what types of antiseptic measures are most commonly used among Saudi plastic surgeons. Methods The authors conducted a cross-sectional survey among board-certified plastic surgeons in Saudi Arabia, collecting data through a self-administered online questionnaire. This questionnaire, which covered their demographic information and their antiseptic practices during breast implant surgery, was disseminated via a WhatsApp (Menlo Park, CA) broadcast message from May 15 to June 27, 2023. Results Of the 52 Saudi plastic surgeons who completed the questionnaire, all reported employing preoperative antibiotics and skin disinfection. Other measures included pocket irrigation (86.5%), implant irrigation (92.3%), sleeve/funnel usage (65.4%), nipple shield usage (51.9%), and glove change during the procedure (96.2%). Nearly, all respondents used only a surgical cap for head cover (96.2%) and postoperative antibiotics as prophylaxis (98.1%). However, more than half of them did not minimize door movement during the procedure (51.9%). Conclusions This study offers a valuable insight into the antiseptic practices during breast implant surgery in Saudi Arabia. The findings underline the need for further research to establish evidence-based guidelines for antiseptic practices in this field. Level of Evidence 5

Abstract
BACKGROUND Capsular contracture is the most common complication of breast implantation surgery. Bacterial contamination was considered to play an important role in the occurrence of capsular contracture, and Gram-positive bacteria such as Staphylococcus epidermidis were discovered in the clinical specimens. Lipoteichoic acid (LTA) was a component of the cell wall of Gram-positive bacteria and was sufficient in the pathogenicity of the bacteria. The authors assumed that LTA could trigger the immunologic response against the implant and cause capsular contracture. METHODS The authors developed a rat model of capsular contracture by repeated injection of 10 μg/mL LTA. The histologic changes of the capsule tissue were measured by hematoxylin and eosin, sirius red, Masson, and immunohistochemical staining. The expression of related cytokines was measured by quantitative real-time polymerase chain reaction. The downstream pathway activation was shown by Western blot. The authors also applied tocilizumab, an interleukin (IL)-6 receptor antagonist, to verify the role of IL-6 in this pathologic process. RESULTS The authors discovered that repeated LTA injection, at a low concentration, could induce the thickening of capsule tissue, the deposition of collagen fiber, and the activation of myofibroblasts. The IL-6/signal transducer and activator of transcription 3 signaling pathway was activated in this process, and the inhibition of IL-6 receptor could relieve the symptoms. B cells and T-helper cells, especially T-helper type 1, could be related to this phenomenon. CONCLUSIONS The authors' research corroborated that subclinical infection could trigger capsular contracture, and the immune system played an important role in this process. The authors' results provided a possible research direction for the mechanism of bacterial infection-induced immune response against breast implants. CLINICAL RELEVANCE STATEMENT The authors' research provides a possible research direction for the mechanism of bacterial infection-induced immune response against breast implants, and a potential target for predicting the prognosis of capsular contracture.

Abstract
BACKGROUND Increasingly patients with unilateral breast cancer elect to undergo bilateral mastectomy with subsequent reconstruction. Studies have aimed to better identify the risks associated with performing mastectomy on the noncancerous breast. Our study aims to identify differences in complications between therapeutic and prophylactic mastectomy in patients undergoing implant-based breast reconstruction. METHODS A retrospective analysis of implant-based breast reconstruction from 2015 to 2020 at our institution was completed. Patients with less than 6-month follow-up after final implant placement had reconstruction using autologous flaps, expander or implant rupture, metastatic disease requiring device removal, or death before completion of reconstruction were excluded. McNemar test identified differences in incidence of complications for therapeutic and prophylactic breasts. RESULTS After analysis of 215 patients, we observed no significant difference in incidence of infection, ischemia, or hematoma between the therapeutic and prophylactic sides. Therapeutic mastectomies had higher odds of seroma formation ( P = 0.03; odds ratio, 3.500; 95% confidence interval, 1.099-14.603). Radiation treatment status was analyzed for patients with seroma; 14% of patients unilateral seroma of the therapeutic side underwent radiation (2 of 14), compared with 25% patients with unilateral seroma of the prophylactic side (1 of 4). CONCLUSIONS For patients undergoing mastectomy with implant-based reconstruction, the therapeutic mastectomy side has an increased risk of seroma formation.

Abstract
INTRODUCTION Capsular contracture is a common complication after 2-stage breast reconstruction. The relationships between native breast size, the rate of tissue expander expansion, and capsule formation have not been elucidated. This study aims to evaluate how these factors contribute to capsular contracture and establish cutoff values for increased risk. METHODS A data set consisting of 229 patients who underwent 2-stage breast reconstruction between 2012 and 2021 was included in the study. The rate of expansion is estimated as the final expanded volume subtracted by the initial filling volume of the tissue expander over time elapsed. The native breast size was estimated using various preoperative breast measurements and the weight of mastectomy specimen (grams). Further stratified analysis evaluated patients separately based on postoperative radiation status. RESULTS Greater nipple-inframammary fold distance and faster tissue expander enlargement rate conferred decreased odds of developing capsular contracture ( P < 0.05). On stratified analysis, faster tissue expansion rate was not significant in the nonradiated cohort but remained a significant negative predictor in the radiation group (odds ratio, 0.996; P < 0.05). Cut-point analysis showed an expansion rate of <240 mL/mo and a nipple-inframammary fold value of <10.5 cm as conferring a greater risk of capsular contracture. CONCLUSION Smaller inframammary fold distance may be associated with a higher risk of capsular contracture. Slower expansion rates correlate with increased odds of contracture in patients undergoing adjuvant radiation. Breast geometry should be considered when risk stratifying various reconstruction approaches (implant vs autologous). In addition, longer delays between implant exchange and initial tissue expansion should be avoided if clinically feasible.

Abstract
Tissue engineering chambers (TECs) have been shown to be useful in regenerating adipose tissue. However, tissue fibrosis caused by the chambers compromises the final volume of the newly formed adipose tissue. Surface modifications can compensate for the lack of biocompatibility of an implant. Tranilast (Tra) is an antifibrotic drug used to treat fibrotic pathologies, including keloids and scleroderma. In this study, a polydopamine-assisted tranilast coating (pDA + Tra) was prepared on a polylactic acid (PLA) chamber to minimize tissue fibrosis and achieve a large volume of fat flap regeneration. The in vitro results showed that, in contrast to a PLA chamber, roughness increased, and the fibroblast adhesion and smooth muscle antibody-positive immunoreactivity decreased in the PLA + pDA + Tra chamber. In addition, pedicled adipose tissue flaps were separated from the back of the rabbit and inserted into each chamber using the classic TEC procedure. After 16 weeks, the marked attenuation of fibrosis and promotion of fat regeneration was observed in the PLA + pDA + Tra chamber in contrast to the PLA chamber. Moreover, in contrast to the PLA chamber, Q-PCR results showed that fibrotic factor TGF-β was significantly reduced, associated with a remarkable increase in adipogenic differentiation transcription factors PPAR-γ and C/EBPα in the PLA + pDA + Tra chamber after 16 weeks (p < 0.05). Thus, PLA chambers loaded with pDA + Tra on the surface have good biocompatibility, and chemical anti-fibrosis reagents can synergistically reduce fibrosis formation while excellently promoting adipose tissue regeneration.

Abstract
With the occurrence of breast implant crises in Korea, it has become increasingly important to detect complications earlier in patients receiving a device. We have therefore combined imaging modalities with an implant-based augmentation mammaplasty. In this study, we assessed the short-term treatment outcomes and safety of the Motiva Ergonomix™ RoundSilkSurface (Establishment Labs Holdings Inc., Alajuela, Costa Rica) in Korean women. A total of 87 women (n = 87) were included in the current study. We compared preoperative anthropometric measurements between the right side and the left side of the breast. Moreover, we also compared the thickness of the skin, subcutaneous tissue and the pectoralis major measured on a breast ultrasound preoperatively and 3 months postoperatively. Furthermore, we analyzed the incidences of postoperative complications and the cumulative complication-free survival. Preoperatively, there was a significant difference in the distance from the nipple to the midline between the left and right side of the breast (p = 0.000). Both sides of the breast showed significant differences in the thickness of the pectoralis major preoperatively and 3 months postoperatively (p = 0.000). A total of 11 cases (12.6%) of postoperative complications occurred; these included five cases (5.7%) of early seroma, two cases (2.3%) of infection, two cases (2.3%) of rippling, one case (1.1%) of hematoma and one case (1.1%) of capsular contracture. Time-to-events were estimated at 386.68 ± 27.79 days (95% CI 334.11–439.27). Here, we describe our experience with imaging modalities in combination with the Motiva ErgonomixTM Round SilkSurface in Korean women.

Abstract
Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a variant of anaplastic large cell lymphoma (ALCL) associated with textured-surface silicone breast implants. Since first being described in 1997, over 1100 cases have been currently reported worldwide. A causal relationship between BIA-ALCL and textured implants has been established in epidemiological studies, but a multifactorial process is likely to be involved in the pathogenesis of BIA-ALCL. However, pathophysiologic mechanisms remain unclear. One of the hypotheses that could explain the link between textured implants and BIA-ALCL consists in the greater tendency of bacterial biofilm in colonizing the surface of textured implants compared to smooth implants, and the resulting chronic inflammation which, in predisposed individuals, may lead to tumorigenesis. This review summarizes the existing evidence on the role of micro-organisms and rough surface implants in the development of BIA-ALCL. It also provides insights into the most updated clinical practice knowledge about BIA-ALCL, from clinical presentation and investigation to treatment and outcomes.

Abstract
In 2011, a syndrome entitled ASIA (Autoimmune/inflammatory Syndrome Induced by Adjuvants; Shoenfeld's syndrome) was first described. ASIA aimed to organize under a single umbrella, the existing evidence regarding certain environmental factors which possess immune stimulatory properties, in order to shed light on a common pathway of autoimmune pathogenesis. Such environmental immune stimulators, or adjuvants, include among others: aluminum salts as in vaccines, various medical implants, as well as various infectious agents. After the launch of the ASIA syndrome, the expansion and recognition of this syndrome by different researchers from different countries began. During the past decades, evidence had been accumulating that (auto)immune symptoms can be triggered by exposure to environmental immune stimulatory factors that act as an adjuvant in genetically susceptible individuals. A panoply of unexplained subjective and autonomic-related symptoms has been reported in patients with ASIA syndrome. The current review summarizes and updates accumulated knowledge from the past decades, describing new adjuvants- (e.g. polypropylene meshes) and vaccine- (e.g. HPV and COVID vaccines) induced ASIA. Furthermore, a direct association between inflammatory/autoimmune diseases with ASIA syndrome, will be discussed. Recent cases will strengthen some of the criteria depicted in ASIA syndrome such as clear improvement of symptoms by the removal of adjuvants (e.g. silicone breast implants) from the body of patients. Finally, we will introduce additional factors to be included in the criteria for ASIA syndrome such as: (1) dysregulated non-classical autoantibodies directed against G-protein coupled receptors (GPCRs) of the autonomic nervous system and (2)) small fiber neuropathy (SFN), both of which might explain, at least in part, the development of 'dysautonomia' reported in many ASIA patients.

Keller Funnel Efficacy in "No Touch" Breast Augmentation and Reconstruction: A Systematic Review. Plast Reconstr Surg Glob Open 2022; 10:e4676. [PMID: 36448016 PMCID: PMC9699649 DOI: 10.1097/gox.0000000000004676] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 09/29/2022] [Indexed: 01/25/2023]
Abstract
UNLABELLED Breast augmentation is one of the most common aesthetic surgical procedures. Tissue expansion followed by permanent implants is the most frequent postmastectomy breast reconstruction method. Implant contamination remains a critical problem with these procedures' resulting in acute infection as well as capsular contracture. To reduce the risk of implant contamination, the "no-touch technique" utilizing the Keller funnel has been adopted by many surgeons. This systematic review aims to investigate the advantages of the Keller funnel method for breast augmentation-reconstruction. METHODS A systematic review of PubMed, Embase, the Cochrane database, and Google Scholar was performed between 2005 and 2021. All clinical-based, retrospective and prospective studies utilizing the Keller funnel method for breast implant insertion were selected. RESULTS Six studies were identified for evaluation: five were retrospective cohorts and one was a prospective trial. No randomized controlled trials were found. Outcomes reported included lower rates of capsular contracture (RR, 0.42; P = 0.0006; 95% CI, 0.25-0.69), shorter incision lengths (35.5 ± 2.1 mm), less insertion time (mean = 6 seconds), and decreased complications, and one paper reported ultimately greater patient satisfaction with outcomes (BREAST-Q Score: 92%). CONCLUSIONS This review suggests that the Keller funnel is a useful method for no-touch breast augmentation and reconstruction surgery. The Keller funnel reduces subsequent capsular contracture rate, surgical time, and incision length and allows for easier insertion. However, our findings support recommendation of a prospective randomized controlled clinical trial with larger population size and follow-up intervals.

Ultrasound Criteria and Baker Scale for Breast Implant Capsular Contracture Diagnosis. Plast Reconstr Surg Glob Open 2022; 10:e4582. [PMID: 36284718 PMCID: PMC9584181 DOI: 10.1097/gox.0000000000004582] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Accepted: 08/16/2022] [Indexed: 11/13/2022]
Abstract
Due to the subjectivity of the Baker scale in grading capsular contracture (CC), an objective and reproducible measurement tool is necessary to estimate the presence and grade of CC in patients with breast implants. This study aimed to assess the capacity of breast ultrasonography to identify CCs using the Baker grading system. Methods This study included patients who underwent breast augmentation with implants or implant-based breast reconstruction. Patient demographics, surgical type, and ultrasonographic variables were analyzed. The Kruskal-Wallis test was used to determine differences between means, and the Fisher exact test was used for binary variables. Results A total of 21 patients (28 breasts) with smooth surface implants were included. In total, 39.2% of breasts had a score of Baker I, 25% had Baker II, 17.9% had Baker III, and 17.9% had Baker IV. When comparing breasts graded Baker I to IV, a mean capsule thickness of 0.6 ± 0.2, 1.0 ± 0.53, 1.68 ± 0.99, and 1.52 ± 0.46 mm, respectively, was shown (P = 0.0044). The breast implant deformity variable was significantly different between Baker grades I to IV (0.0218). Finally, Baker III and IV categories were five times more likely to have abnormal wrinkles than Baker I and II (odds ratio, 5.25; 95% confidence interval, 0.82-33.45; P = 0.0496). Conclusion Ultrasound is a useful tool for evaluating the presence of augmented thickness, implant shape deformity, and abnormal wrinkles of the implant shell in correlation with the severity of CC.

An Experimental Murine Model to Assess Biofilm Persistence on Commercial Breast Implant Surfaces. Microorganisms 2022; 10:microorganisms10102004. [PMID: 36296280 PMCID: PMC9611056 DOI: 10.3390/microorganisms10102004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 09/29/2022] [Accepted: 10/08/2022] [Indexed: 11/16/2022] Open
Abstract
Capsular contracture is the most frequently associated complication following breast implant placement. Biofilm formation on the surface of such implants could significantly influence the pathogenesis of this complication. The objective of this study was to design an experimental model of breast implant infection that allowed us to compare the in vivo S. epidermidis ability to form and perpetuate biofilms on commonly used types of breast implants (i.e., macrotexturized, microtexturized, and smooth). A biofilm forming S. epidermidis strain (ATCC 35984) was used for all experiments. Three different implant surface types were tested: McGhan BIOCELL® (i.e., macrotexturized); Mentor Siltex® (i.e., microtexturized); and Allergan Natrelle Smooth® (i.e., smooth). Two different infection scenarios were simulated. The ability to form biofilm on capsules and implants over time was evaluated by quantitative post-sonication culture of implants and capsules biopsies. This experimental model allows the generation of a subclinical staphylococcal infection associated with a breast implant placed in the subcutaneous tissue of Wistar rats. The probability of generating an infection was different according to the type of implant studied and to the time from implantation to implant removal. Infection was achieved in 88.9% of macrotextured implants (i.e., McGhan), 37.0% of microtexturized implants (i.e., Mentor), and 18.5% of smooth implants (i.e., Allergan Smooth) in the short-term (p < 0.001). Infection was achieved in 47.2% of macrotextured implants, 2.8% of microtexturized implants, and 2.8% of smooth implants (i.e., Allergan Smooth) in the long-term (p < 0.001). There was a clear positive correlation between biofilm formation on any type of implant and capsule colonization/infection. Uniformly, the capsules formed around the macro- or microtexturized implants were consistently macroscopically thicker than those formed around the smooth implants regardless of the time at which they were removed (i.e., 1−2 weeks or 3−5 weeks). We have shown that there is a difference in the ability of S epidermidis to develop in vivo biofilms on macrotextured, microtextured, and smooth implants. Smooth implants clearly thwart bacterial adherence and, consequently, biofilm formation and persistence are hindered.

Abstract
Capsular contracture as a result of the foreign body response (FBR) is a common issue after implant-based breast reconstruction, affecting up to 20% of patients. New evidence suggests that tamoxifen may mitigate the FBR. C57BL/6 female mice were treated with daily tamoxifen or control injections and implanted with bilateral silicone implants in the submammary glandular plane. Implants were removed en bloc after 2 weeks and the implant capsules were evaluated histologically. Tamoxifen treatment decreased capsule thickness, decreased the number of αSMA+ cells (477 ± 156 cells/mm control vs 295 ± 121 cells/mm tamoxifen, p = 0.005 unpaired t test), and decreased CD31+ cells (173.9 ± 96.1 cells/mm2 control vs 106.3 ± 51.8 cells/mm2 tamoxifen, p = 0.043 unpaired t test). There were similar amounts of pro- and anti-inflammatory macrophages (iNOS 336.1 ± 226.3 cells/mm control vs 290.6 ± 104.2 cells/mm tamoxifen, p > 0.999 Mann-Whitney test and CD163 136.6 ± 76.4 cells/mm control vs 94.1 ± 45.9 cells/mm tamoxifen, p = 0.108 unpaired t test). Tamoxifen treatment in the mouse silicone breast implant model decreased capsule formation through modulation of myofibroblasts, neovascularization, and collagen deposition. Tamoxifen may be useful for reducing or preventing capsule formation in clinical breast implantations.

Abstract
BACKGROUND Intraoperative contamination of the surgical field during aesthetic breast augmentation may lead to implant infection with devastating consequences. This study covers a period of 30 years and is divided into 2 phases: a retrospective phase from 1992-2004 when a standard approach was used and a prospective phase from 2004-2022 when a no-touch approach was implemented to avoid contamination. METHODS Patients in the standard and no-touch groups underwent aesthetic breast augmentation by the same senior surgeon (FDP) in the same outpatient surgical facility during the 30-year period of the study. Patients are divided into 2 groups: from 1992-2004 and from the implementation of the no-touch protocol in 2004-2022. RESULTS Patients who underwent breast augmentation using the no-touch approach developed no infections, whereas the standard group had an infection rate of 3.54% (P = .017). The validity of this finding is discussed. CONCLUSIONS The no-touch approach as described in this article was effective in reducing implant infection rate when performing aesthetic breast augmentation by 1 surgeon at 1 surgical center during an 18-year observation period. Multicenter prospective cooperative studies are necessary to validate perioperative iatrogenic contamination as the cause of implant infection and to explore optimal approaches that could eliminate implant contamination.

Abstract
Cutibacterium acnes (C. acnes, formerly Propionibacterium acnes) is considered to be a non-pathogenic resident of the human skin, as well as mucosal surfaces. However, it also has been demonstrated that C. acnes plays a pathogenic role in diseases such as acne vulgaris or implant infections after orthopedic surgery. Besides a role in infectious disease, this bacterium also seems to harbor immunomodulatory effects demonstrated by studies using C. acnes to enhance anti-tumor activity in various cancers or vaccination response. Sarcoidosis is a systemic inflammatory disorder of unknown causes. Cultures of C. acnes in biopsy samples of sarcoidosis patients, its presence in BAL fluid, tissue samples as well as antibodies against this bacterium found in serum of patients with sarcoidosis suggest an etiological role in this disease. In this review we address the antigenic as well as immunomodulatory potential of C. acnes with a focus on sarcoidosis. Furthermore, a potential role for antibiotic treatment in patients with sarcoidosis will be explored.

Abstract
Capsular contracture is a common complication associated with breast implants following reconstructive or aesthetic surgery in which a tight or constricting scar tissue capsule forms around the implant, often distorting the breast shape and resulting in chronic pain. Capsulectomy (involving full removal of the capsule surrounding the implant) and capsulotomy (where the capsule is released and/or partly removed to create more space for the implant) are the most common surgical procedures used to treat capsular contracture. Various structural modifications of the implant device (including use of textured implants, submuscular placement of the implant, and the use of polyurethane-coated implants) and surgical strategies (including pre-operative skin washing and irrigation of the implant pocket with antibiotics) have been and/or are currently used to help reduce the incidence of capsular contracture. In this article, we review the pharmacological approaches-both commonly practiced in the clinic and experimental-reported in the scientific and clinical literature aimed at either preventing or treating capsular contracture, including (i) pre- and post-operative intravenous administration of drug substances, (ii) systemic (usually oral) administration of drugs before and after surgery, (iii) modification of the implant surface with grafted drug substances, (iv) irrigation of the implant or peri-implant tissue with drugs prior to implantation, and (v) incorporation of drugs into the implant shell or filler prior to surgery followed by drug release in situ after implantation.

Abstract
Background Bacterial biofilm can occur on all medical implanted devices and lead to infection and/or dysfunction of the device. In this study, artificial biofilm was formed on four different medical implants (silicone, piccline, peripheral venous catheter and endotracheal tube) of interest for our daily clinical and/or research practice. We investigated the best conventional technic to dislodge the biofilm on the implants and quantified the number of bacteria. Staphylococcus epidermidis previously isolated from a breast implant capsular contracture on a patient in the university hospital of Dijon was selected for its ability to produce biofilm on the implants. Different technics (sonication, Digest-EUR®, mechanized bead mill, combination of sonication plus Digest-EUR®) were tested and compared to detach the biofilm before quantifying viable bacteria by colony counting. Results For all treatments, the optical and scanning electron microscope images showed substantial less biofilm biomass remaining on the silicone implant compared to non-treated implant. This study demonstrated that the US procedure was statistically superior to the other physical treatment: beads, Digest-EUR® alone and Digest-EUR® + US (p < 0.001) for the flexible materials (picc-line, PIV, and silicone). The number of bacteria released by the US is significantly higher with a difference of 1 log on each material. The result for a rigid endotracheal tube were different with superiority for the chemical treatment dithiothreitol: Digest-EUR®. Surprisingly the combination of the US plus Digest-EUR® treatment was consistently inferior for the four materials. Conclusions Depending on the materials used, the biofilm dislodging technique must be adapted. The US procedure was the best technic to dislodge S. epidermidis biofilm on silicone, piccline, peripheral venous catheter but not endotracheal tube. This suggested that scientists should compare themselves different methods before designing a protocol of biofilm study on a given material.

Abstract
BACKGROUND The precise etiology and treatment for capsular contracture remains uncertain at least partially due to the fact that there is no reliable quantitative measurement tool. To address this, it is postulated that the surface area of an implant as defined by the surrounding pocket may provide a quantifiable variable that can be measured to evaluate the degree of capsular contracture. METHODS A bench model for capsular contracture was developed. The surface area of a series of spherical test objects and non-contracted and contracted breast implants was measured using a wax coating technique as well as three-dimensional reconstructions created from CT scan images. RESULTS Comparison of the mathematically calculated surface areas to the wax and CT results for spheres of known dimension provided nearly identical values documenting the accuracy of the two experimental methods. Comparison of the surface area measurements between the test groups showed that the average decrease in surface area for all implants was 20%, ranging from a high of 30.9% for a low profile implant to a low of 14.1 % for a high profile implant. The anatomically shaped devices demonstrated nearly uniform degrees of surface area change over three different heights with volume and projection held relatively constant. CONCLUSIONS The described bench model provides a useful tool for the study of capsular contracture. Surface area is a descriptive variable that can assess the degree of capsular contracture that is present. A classification system based on surface area is presented.

Proteome of Staphylococcus aureus Biofilm Changes Significantly with Aging. Int J Mol Sci 2022; 23:ijms23126415.

Abstract
Staphylococcus aureus is a notorious biofilm-producing pathogen that is frequently isolated from implantable medical device infections. As biofilm ages, it becomes more tolerant to antimicrobial treatment leading to treatment failure and necessitating the costly removal of infected devices. In this study, we performed in-solution digestion followed by TMT-based high-throughput mass spectrometry and investigated what changes occur in the proteome of S. aureus biofilm grown for 3-days and 12-days in comparison with 24 h planktonic. It showed that proteins associated with biosynthetic processes, ABC transporter pathway, virulence proteins, and shikimate kinase pathway were significantly upregulated in a 3-day biofilm, while proteins associated with sugar transporter, degradation, and stress response were downregulated. Interestingly, in a 3-day biofilm, we observed numerous proteins involved in the central metabolism pathways which could lead to biofilm growth under diverse environments by providing an alternative metabolic route to utilize energy. In 12-day biofilms, proteins associated with peptidoglycan biosynthesis, sugar transporters, and stress responses were upregulated, whereas proteins associated with ABC transporters, DNA replication, and adhesion proteins were downregulated. Gene Ontology analysis revealed that more proteins are involved in metabolic processes in 3dwb compared with 12dwb. Furthermore, we observed significant variations in the formation of biofilms resulting from changes in the level of metabolic activity in the different growth modes of biofilms that could be a significant factor in S. aureus biofilm maturation and persistence. Collectively, potential marker proteins were identified and further characterized to understand their exact role in S. aureus biofilm development, which may shed light on possible new therapeutic regimes in the treatment of biofilm-related implant-associated infections.

Abstract
Breast implant illness refers to a combination of different symptoms related to breast implant surgery, including fatigue, brain fog, and arthralgias. This malaise occurs after cosmetic and reconstructive breast surgeries, although it has not been proven to be a disease. Even recent studies have reported concluding statements of the etiology, diagnosis, and treatment as unclear and widely unknown. Therefore, this review aimed to determine the associations between the manifestations of breast implant illness in surgery and breast reconstruction, as well as the autoimmune responses involved. Complications associated with breast implants include breast pain, capsular contracture, infections, as well as other manifestations specific to breast reconstruction. Moreover, patients with implants may present with new-onset systemic sclerosis, Sjögren’s syndrome, and connective tissue diseases. However, the incidence of capsular contracture has steadily decreased with each generation of implants, particularly since the development of textured implants, as well as with the use of antibiotics and antiseptic pocket irrigation. However, the incidence of anaplastic large cell lymphoma has increased with the use of textured implants. Remarkably, the autoimmune response to these implants remains unclear. Therefore, close follow-up, careful observation of any symptom presentation, and evidence-based treatment decisions are necessary for patients with breast implants.

Abstract
The spread of biofilms on medical implants represents one of the principal triggers of persistent and chronic infections in clinical settings, and it has been the subject of many studies in the past few years, with most of them focused on prosthetic joint infections. We review here recent works on biofilm formation and microbial colonization on a large variety of indwelling devices, ranging from heart valves and pacemakers to urological and breast implants and from biliary stents and endoscopic tubes to contact lenses and neurosurgical implants. We focus on bacterial abundance and distribution across different devices and body sites and on the role of environmental features, such as the presence of fluid flow and properties of the implant surface, as well as on the interplay between bacterial colonization and the response of the human immune system.

Abstract
Because breast augmentation is one of the most popular cosmetic procedures, the issue of implant-related complications has been widely debated ever since the FDA approved the use of implants in 1962. Although decades have passed, breast implant illness (BII) still represents a poorly defined and controversial complication. With ongoing nonscientific discussion in the mainstream media and on social media, revealing the etiology of BII is urgent because knowledge of this subject ultimately influences patients' decisions. Little or no scientific research is currently available on BII and no final conclusions regarding its etiology, clinical manifestations, diagnostic criteria, or treatment have been made. This review aims to give an overview of the hypotheses on the etiology of BII and seeks inspiration to improve the conditions of BII patients.

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. The etiopathogenesis of BIA-ALCL is likely to be multifactorial, with current evidence-based theories recognising the combination of chronic infection in setting of textured implants, gram-negative biofilm formation, chronic inflammation, host genetics (e.g. JAK/STAT, p53) and time in tumorigenesis. Proposed triggers for the development of malignancy are mechanical friction, silicone implant shell particulates, silicone leachables and bacteria. Of these, the bacterial hypothesis has received significant attention, supported by a plausible biological model. In this model, bacteria form an adherent biofilm in the favourable 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. Future research, investigating BIA-ALCL genetic mutations and immunological modulation with Gram-negative biofilm in BIA-ALCL models is warranted to establish a unifying theory for the aetiology of BIA-ALCL.

Abstract
INTRODUCTION More than one million breast augmentation procedures using silicone breast implants (SBI) have been performed worldwide. Adverse events of SBI include local complications such as pain, swelling, redness, infections, capsular contracture, implant rupture and gel-bleed. Furthermore, patients experience systemic symptoms such as chronic fatigue, arthralgias, myalgias, pyrexia, sicca, and cognitive dysfunction. These symptoms received different names such as autoimmune/inflammatory syndrome induced by adjuvants (ASIA) due to silicone incompatibility syndrome and breast implant illness (BII). Because of chronic immune activation, BII/ASIA, allergies, autoimmune diseases, immune deficiencies and finally lymphomas may develop in SBI patients. AREAS COVERED Causality for SBI-related BII/ASIA is reviewed. To address the role of silicone implants in promoting causality, we utilized the Bradford-Hill criteria, with results highlighted in this article. EXPERT OPINION We conclude that there is a causal association between SBIs and BII/ASIA. Using data derived from patients with BII/ASIA and from other medically implanted devices, there appears to be clear pathogenic relationship between SBI and BII/ASIA. Breast implants cause characteristic systemic reactions in certain women, leading to symptoms of sufficient severity to warrant device removal. The morbidity suffered is variable. SBI removal resolves the symptoms in most women and removal is the most effective treatment.

Abstract
OBJECTIVE Breast surgery is considered a clean surgery; however, the rates of infection range between 3 and 15%. The objective of the present study was to intraoperatively investigate the presence of autochthonous microbiota in the breast. METHODS Pieces of breast tissue collected from 49 patients who underwent elective breast surgery (reconstructive, diagnostic, or oncologic) were cultured. The pieces of breast tissue were approximately 1 cm in diameter and were removed from the retroareolar area, medial quadrant, and lateral quadrant. Each piece of tissue was incubated in brain heart infusion (BHI) broth for 7 days at 37°C, and in cases in which the medium became turbid due to microorganism growth, the samples were placed in Petri dishes for culturing and isolating strains and for identifying species using an automated counter. RESULTS Microorganism growth was observed in the samples of 10 of the 49 patients (20.4%) and in 11 of the 218 pieces of tissue (5%). The detected species were Staphylococcus lugdunensis, Staphylococcus hominis, Staphylococcus epidermidis, Sphingomonas paucimobilis, and Aeromonas salmonicida. No patient with positive samples had clinical infection postoperatively. CONCLUSION The presence of these bacteria in breast tissue in approximately 20% of the patients in this series suggests that breast surgery should be considered a potential source of contamination that may have implications for adverse reactions to breast implants and should be studied in the near future for their oncological implications in breast implant-associated large-cell lymphoma etiology.

Abstract
Breast implant insertion funnels have become popular adjuncts to breast implant surgery to reduce access incision length and contact of the implant with the skin of the breast. Although labeled as single-use devices, due to cost considerations, many surgeons use a new breast implant insertion funnel with each patient rather than each breast. The purpose of this study was to evaluate the prevalence of capsular contracture of the first augmentation side and compare it to the second side utilizing one insertion funnel per patient.

Abstract
Essure (TM, Bayer; Leverkusen, Germany) may act as a potential cause of autoimmune/inflammatory syndrome by adjuvants (ASIA). Essure is a device hysteroscopically inserted into the fallopian tubes to elicit a local inflammatory response for permanent sterilization. Patients with ASIA present with a constellation of symptoms including fatigue, cognitive impairment, and arthralgias. It is well known that ASIA is triggered by implantation of foreign material such as breast implants and mesh for hernia repair. In the current study, we present a retrospective cohort of 33 patients electing to remove Essure due to pelvic pain and systemic symptoms consistent with an ASIA diagnosis, and detail a case report of an Essure patient. Furthermore, we reviewed the existing literature on adverse events associated with Essure and studies assessing outcomes following explantation. The concept that Essure may trigger ASIA is further supported by both in vivo and in vitro studies demonstrating immunostimulatory effects of the material components of the device. We conclude that the existing evidence is sufficient to recommend screening of Essure recipients for ASIA symptoms, and where indicated, discussion of the risks and potential benefits of surgical removal.

Abstract
Capsular contracture is fundamentally an immunological/inflammatory response to the implant, treating it as a foreign body in need of exclusion from the immune system. The capsule surrounding the implant is populated by a rich variety of immunologically active cells such as macrophages, T lymphocytes, and myofibroblasts. Vaccination in general and the COVID-19 vaccine in particular result in specific and nonspecific activation of the immune system, including those immune cells in proximity to the implant. This phenomenon has been previously demonstrated in delayed inflammatory reactions to previously implanted hyaluronic acid fillers following COVID-19 vaccination. This report is what is believed to be the first case of the rapid development of severe ipsilateral capsular contracture in the immediate aftermath of the second dose of the BNT162b2 (Pfizer) vaccine.

Abstract
BACKGROUND In two-stage prosthetic breast reconstruction, two types of tissue expanders are used for the first stage: microtextured Siltex and macrotextured Biocell. Despite emerging concerns regarding the safety of macrotextured prostheses, the association between the use of macrotextured expanders and adverse outcomes remains unknown clinically. This study aimed to evaluate potential impacts of the type of tissue expander on the long-term outcomes of implant-based breast reconstruction. METHODS Patients who underwent immediate two-stage tissue expander/implant breast reconstruction between 2014 and 2018 were evaluated and categorized into two groups according to the expander type. Those two were propensity score matched for baseline characteristics and compared for complication rates after the first- and second-stage operations. The impacts of several variables, including type of tissue expander used, on outcomes were assessed using multivariable logistic regression analyses. RESULTS Of the 1391 cases in 1294 patients, 276 pairs (552 cases) were successfully propensity score matched. In the first-stage operation, the macrotextured group showed a significantly shorter drain indwelling period and lower rate of seroma than the microtextured group. These differences retained influences after adjusting for other variables. Incidence rates of other complications were similar between the groups. Regarding the second-stage operation, the use of macrotextured expanders showed a significant association, with an increased rate of severe capsular contracture on the multivariable analyses in cases using textured implants. Development of other complications was not affected by the expander type. CONCLUSION The type of tissue expander might influence the outcomes of two-stage implant-based breast reconstruction, and generally acceptable safety of both microtextured and macrotextured expanders was shown.
