Abstract
INTRODUCTION Breast augmentation remains one of the most prevalent procedures in plastic surgery. While most patients experience high satisfaction with the outcomes, a subset may encounter various complications or dissatisfaction with achieved results necessitating subsequent surgical intervention including implant removal or exchange. MATERIALS AND METHODS We collected information from three pivotal private medical centers in Israel where a considerable number of breast surgeries are performed. We examined the number of breast augmentations, implant exchange and implant removal surgeries with or without breast lift that were performed on a biannual basis for each center for the period 2018-2022. Trends in surgery types were analyzed and compared to registries in other countries. RESULTS Between the years 2018 and 2022, 20,075 surgeries were done in three main private medical centers in Israel. Data show a gradual increase in implant removal surgeries from 2018 (n = 80, 2.9%) to 2019 (n = 269, 9.9%), followed by a significant increase in 2020 (n = 1436, 27.3%), and a gradual decline between 2021 (n = 1019, 22.8%) and 2022 (n = 916, 18.5%). The overall number of breast implant insertion procedures (breast augmentation procedures and exchange procedures) was 2659 in 2018 (97%), 2424 in 2019 (90.0%), 3816 in 2020 (72.6%), 3437 in 2021 (77.1%), and 4019 in 2022 (81.4%). SUMMARY We present updated trends in breast implant surgeries in Israel. 2020 was a key year in which the rate of explantations was the highest, and the percentage rate of implantations was the lowest and a year in which the trend changed. These patterns partly align with trends seen in other countries worldwide.

Abstract
Autoimmune/autoinflammatory syndrome induced by adjuvants (ASIA) was first described in 2011 to cover disorders characterized by dysregulation of the immune system after exposure to an adjuvant. In the present review, the authors focus on silicone-induced ASIA. In the last two decades, there has been worldwide increase in the use of silicone breast implant (SBI) as an aesthetic procedure, raising concerns for possible effects on the immune system, especially in people who already have previous immune dysregulation. The authors did a critical review of the most important articles referring to silicone-induced ASIA, including most recent studies regarding physiopathologic mechanism. Despite large-scale epidemiological studies conducted to assess the association between SBI and autoimmune/rheumatic disorders, the results remain inconclusive, and the debate over the safety of SBIs remains heated. The explantation of silicone breast has been indicated for silicone-induced ASIA with improvement of unspecific symptoms in the majority of patients; however, the outcome seems different in patients with definitive autoimmune rheumatic disease (AIRD). There is no prospective study evaluating the risk of flares after SBI in patients who already have an AIRD. Therefore, based on the literature, we cannot contraindicate the procedure; however, we need to advertise about the risk of ASIA to the patients with AIRD. Long-term safety and implant-related outcomes should be discussed with these patients, considering each case individually, assessing genetic and environmental factors, and determining if the autoimmune disease is in remission or not, for shared decision among patient and the physician.

Abstract
Silicone breast implant ruptures have been widely reported in the literature. Granuloma formation is a known complication of such ruptures with reported sites including the axillae, limbs, chest wall muscles, and internal organs, such as the lungs and the liver. To the best of our knowledge, there are no reported cases of a silicone granuloma causing osteomyelitis of the sternum and multiple ribs in the absence of infection. We therefore report on the case of an 81-year-old patient who presented with an anterior chest wall discharging sinus tract on the background of a ruptured silicone breast implant. We raise awareness about the potentially devastating complications resulting from a ruptured silicone implant with relevance to cardiothoracic practice.

Abstract
"Silicone breast implants are the most widely used medical devices for breast reconstruction and augmentation, and revision, but even after more than 60 years of use they are associated with multiple continued complications. Using advancement in current technologies, researchers are attempting to create an optimal implant surface for patients. Through these efforts, plastic surgeons and material researchers have made great progress in the field of implant research. Multimodal techniques for the functional modification of implant surfaces will contribute to further the development of ideal biomaterials useful in breast implants.

Abstract
Background Capsular contracture is one of the most common complications in surgical interventions for aesthetic breast augmentation or post-mastectomy breast reconstruction involving the use of silicone prostheses. Although the precise cause of capsular contracture is yet unknown, the leading hypothesis is that it is caused by long-term unresolved foreign body reaction towards the silicone breast implant. To authors’ best knowledge, this is the first study that elucidates the presence of lysyl oxidase (LOX)—an enzyme that is involved in collagen and elastin crosslinking within fibrous capsules harvested from patients with severe capsular contracture. It was hypothesized that over-expression of LOX plays a role in the irreversible crosslinking of collagen and elastin which, in turn, stabilizes the fibrous proteins and contributes to the progression of capsular contracture. Methods Eight fibrous capsules were collected from patients undergoing capsulectomy procedure, biomechanical testing was performed for compressive Young’s moduli and evaluated for Type I and II collagen, elastin and LOX by means of non-linear optical microscopy and immunohistology techniques. Results Observations revealed the heterogeneity of tissue structure within and among the collected fibrous capsules. Regardless of the tissue structure, it has been shown that LOX expression was intensified at the implant-to-tissue interface. Conclusion Our results indicate the involvement of LOX in the initiation of fibrous capsule formation which ultimately contributes towards the progression of capsular contracture.

Abstract
BACKGROUND Macro-texturing of breast implants was developed with the double goal of improving implant stabilization within the breast cavity and decreasing the rate of capsular contractures. However, recent evidence suggests that double capsular formation, a potentially worrisome phenomenon associated with late seromas and biofilms, occurs with preponderance in macro-textured implants. Our objective was to analyze histologically different regions of double capsules to determine if they are more prone to mechanical movements. METHODS A prospective analysis including patients undergoing second-stage expander to definitive breast-implant reconstruction post-mastectomy was conducted after intraoperative identification of the double capsule phenomenon. Two samples were collected from each capsules around the implant, located centrally and laterally. The specimens were sent for histological analysis by the institution's pathologist. RESULTS In total, 10 patients were identified intraoperatively with partial double capsule phenomenon. Among samples retrieved from the lateral aspect of the breast implant, all were associated with delamination and fractures in the collagen matrix of the double capsules. This phenomenon was not observed in any sample from the dome of the breast. CONCLUSIONS Breast-implant macro-texturing plays an important role on delamination of capsules on lateral portions of the breast, which may have an etiologic role in double capsule formation. Manufacturing implants with macro-texturing on one side and smooth surface on the other could diminish mechanical shear forces responsible for these findings.

Abstract
Despite some case reports and small series of women with silicone breast implants (SBI) developing Systemic Sclerosis (SSc), no clear evidence of an association of SBI with SSc is available. However, SSc is characterized by clinical and immunological heterogeneity and autoantibodies are currently the best markers to stratify this heterogeneity of patients. Therefore, we have reviewed the literature for details of autoantibody characterization in reports of SSc associated with SBI. Moreover, the case of an anti-RNA polymerase III-positive SSc with rapid onset and progression, in which SBI rupture was found is described. This case may support a previous observation suggesting a possible role of SBI rupture as a trigger for anti-RNA polymerase III-positive SSc. This possible causal role may be reinforced by the observation that in our patient, despite immunosuppressive treatment, the disease progressed until SBI were removed, and reduction of anti-RNA polymerase III titer was obtained after rituximab treatment. This result may support data suggesting that B-cell depleting therapy may decrease specific autoantibody level in SSc patients, and that these changes are associated with disease improvement.

Abstract
BACKGROUND Silicone implants have been successfully used for breast augmentation and reconstruction in millions of women worldwide. The reaction to the silicone implant is highly variable; it can lead to local inflammatory symptoms, and sometimes to systemic symptoms and disease. Over 80 cases of anaplastic lymphoma kinase-negative anaplastic large cell lymphoma have been reported in patients with silicone breast implants and have been accepted as a new clinical entity. To the best of our knowledge, an intravascular large B-cell lymphoma associated with a silicone breast implant has not been reported previously. CASE PRESENTATION A 48-year-old Caucasian woman who presented with high fever was found to have splenomegaly on physical examination. A laboratory diagnosis revealed pancytopenia, hypertriglyceridemia, and hyperferritinemia. She developed signs of altered sensorium, hemiparesis, aphasia, and cauda equina syndrome. On further evaluation, she fulfilled the necessary five out of eight criteria for diagnosis of macrophage activation syndrome/hemophagocytic lymphohistiocytosis. Dexamethasone administration was followed by prompt improvement; however, 3 days later she again manifested high fever, which persisted despite administration of immunoglobulin and cyclosporine A. Her silicone breast implant was considered a possible contributor to her macrophage activation syndrome and was therefore removed. A histological examination of the capsule tissue showed an extensive lymphohistiocytic/giant cell foreign body reaction suggestive of autoimmune/inflammatory syndrome induced by adjuvants. However, the histological examination unexpectedly also revealed an intravascular large B-cell lymphoma. CONCLUSIONS The genetic background of our patient with silicone breast implants might have predisposed her to three rare and difficult to diagnose syndromes/diseases: macrophage activation syndrome/hemophagocytic lymphohistiocytosis, autoimmune/inflammatory syndrome induced by adjuvants, and intravascular large B-cell lymphoma. The simultaneous manifestation of all three syndromes suggests causal interrelationships. Human leukocyte antigen testing in all women who undergo silicon breast implantation could in the future enable us to better evaluate the risk of potential side effects.

Abstract
New technology related to artificial organs is most attractive for worldwide researchers. We believe they must contribute for the future patients against untreatable diseases. Regulatory science is a new science to establish 'social acceptance' of new technology into the clinical market as soon as possible. In the history of silicone breast implants, we could recognize risks many times; however, we missed such chances to prevent a subsequent crisis. We analyzed the trend of published literature related to silicone breast implants to review the medical professionals' interests on such risks. This trend showed, despite issues of a social acceptance of silicone breast implants in a few countries, other countries' medical professionals had no interest. Our hypothesis is 'medical professionals face the government and do not have contributed to re-establish the social acceptance of new technologies for patients'. Any technology does not have the complete evidence of safety, efficacy and quality, despite regulatory authorities' review and approval with clinical evidences. medical professionals need to conduct subsequently the epidemiological study, to take a meta-analysis periodically and to create/update the guidance for their patients under their professional ethics after the marketing of new technologies. We need to take seriously the 'lesson learned' from the history of silicone breast implants for all kind of new technologies existed in the present.

Abstract
Reproducing extracellular matrix topographical cues, such as those present within acellular dermal matrix (ADM), in synthetic implant surfaces, may augment cellular responses, independent of surface chemistry. This could lead to enhanced implant integration and performance while reducing complications. In this work, the hierarchical micro and nanoscale features of ADM were accurately and reproducibly replicated in polydimethylsiloxane (PDMS), using an innovative maskless 3D grayscale fabrication process not previously reported. Human breast derived fibroblasts (n=5) were cultured on PDMS surfaces and compared to commercially available smooth and textured silicone implant surfaces, for up to one week. Cell attachment, proliferation and cytotoxicity, in addition to immunofluorescence staining, SEM imaging, qRT-PCR and cytokine array were performed. ADM PDMS surfaces promoted cell adhesion, proliferation and survival (p=<0.05), in addition to increased focal contact formation and spread fibroblast morphology when compared to commercially available implant surfaces. PCNA, vinculin and collagen 1 were up-regulated in fibroblasts on biomimetic surfaces while IL8, TNFα, TGFβ1 and HSP60 were down-regulated (p=<0.05). A reduced inflammatory cytokine response was also observed (p=<0.05). This study represents a novel approach to the development of functionalised biomimetic prosthetic implant surfaces which were demonstrated to significantly attenuate the acute in vitro foreign body reaction to silicone.

Abstract
Primary breast lymphoma represents less than 1% of all primary breast malignancies and most primary breast lymphomas are of B-Cell origin. The association of anaplastic lymphoma kinase (ALK) negative anaplastic large cell lymphoma (ALCL), a very rare form of primary breast lymphoma, with silicone-filled breast implants has been suggested and several case reports supported this proposal, especially in Western countries. Here we describe one of the first cases of primary breast ALK-negative ALCL in association with saline-filled silicone breast implants evaluated in Iran, where the rising number of breast reconstructive and aesthetic surgeries would commit both surgical pathologists and plastic surgeons to be familiar with this entity.
