Immediate prepectoral versus submuscular breast reconstruction in nipple-sparing mastectomy: a retrospective cohort analysis.

Objective: To evaluate early complications in prepectoral breast reconstruction. Methods: A retrospective cohort study including 180 consecutive cases of nipple-sparing mastectomy, comparing immediate breast reconstruction with subpectoral to prepectoral mammary implants in 2012-2022. Clinical and demographic characteristics and complications in the first three months following surgery were compared between the two techniques. Results: The prepectoral technique was used in 22 cases (12.2%) and the subpectoral in 158 (87.8%). Median age was higher in the prepectoral group (47 versus 43.8 years; p=0.038), as was body mass index (25.1 versus 23.8; p=0.002) and implant volume (447.5 versus 409 cc; p=0.001). The prepectoral technique was more associated with an inframammary fold (IMF) incision (19 cases, 86.4% versus 85, 53.8%) than with periareolar incisions (3 cases, 13.6% versus 73, 46.2%); (p=0.004). All cases in the prepectoral group underwent direct-to-implant reconstruction compared to 54 cases (34.2%) in the subpectoral group. Thirty-eight complications were recorded: 36 (22.8%) in the subpectoral group and 2 (9.1%) in the prepectoral group (p=0.24). Necrosis of the nipple-areola complex/skin flap occurred in 27 patients (17.1%) in the subpectoral group (prepectoral group: no cases; p=0.04). The groups were comparable regarding dehiscence, seroma, infection, and hematoma. Reconstruction failed in one case per group (p=0.230). In the multivariate analysis, IMF incision was associated with the prepectoral group (aOR: 34.72; 95%CI: 2.84-424.63). Conclusion: The incidence of early complications was comparable between the two techniques and compatible with previous reports. The clinical and demographic characteristics differed between the techniques. Randomized clinical trials are required.

A Decalogue on Enhanced Recovery After Breast Augmentation Surgery (ERABAS).

BACKGROUND: Medical and technical advances have changed the state of postoperative surgical patient care, allowing for better and faster recovery. Since its publication, predictable 24-hour recovery in breast augmentation surgery has been controversial and has generated discussion. In this study, we present a novel, easy, and reproducible protocol for Enhanced Recovery After Breast Augmentation Surgery (ERABAS), along with a summary of the ten points to follow. METHODS: We conducted a retrospective study of all primary breast augmentation surgeries performed between 2010 and 2020 by a private activity. All surgeries were performed by the same surgeon according to the same protocol, and all implants were obtained from the same company. Data were evaluated using two binary logistic regression models, taking as variables responses to recovery time and postoperative pain and as predictor or explanatory variables to the factors age, smoking, size, and location of the implant. RESULTS: In total, 2906 patients were included in this study. Of these, 2770 patients (95%) immediately returned to normal life within the first 24 h, 129 achieved normal life in four days, and only seven needed a week to recover. In these seven patients, the main acute complications were hemorrhage and acute hematoma. The implants were always round; textured implants were used in 88.8% of patients, while smooth implants were used in 11.2%. A subfascial pocket was used in 934 patients, and a dual-plane pocket was performed for 1972 patients. The only factor that showed a significant effect on recovery time was the location of the implant (p < 0.05), with the dual-plane pocket being the intervention associated with a later recovery, specifically a probability of recovery after 24 hour, 2.86 times greater than subfascial. CONCLUSIONS: The ERABAS protocol allowed rapid return to daily activities with low complication rates. Further prospective comparative multicenter studies are required to confirm these results.

Achados incomuns em ressonância magnética de pacientes com implantes mamários / Unusual findings on MRI of patients with breast implants

Introdução: O implante de prótese mamárias é uma das cirurgias mais realizadas no mundo. Ao longo do tempo, diversos materiais foram utilizados com objetivo de reconstituir o volume mamário. Apesar das melhorias técnicas, cirúrgicas e da segurança dos implantes atuais, os pacientes são confrontados com potenciais complicações "não usuais": rupturas intracapsulares e extracapsulares, hematomas tardios e deformidade de contorno, silicone intralinfonodal ou herniação da cápsula fibrosa. A ressonância magnética (RMN) é a modalidade de imagem mais útil para investigação dessas complicações. Método: Trata-se de uma série de casos em que foram levantadas alterações ditas "não usuais", pela baixa frequência ou ausência na citação da literatura, após cirurgias de inclusão de prótese de silicone. Os dados foram coletados da experiência pessoal da clínica privada de um dos autores, na cidade de Brasília-DF, entre abril de 2015 e março de 2023. Resultados: Foram um total de 211 pacientes avaliados, e foram encontradas alterações menos frequentes nas RMN de 12 pacientes (5,68%), das quais: 5 com volumosa quantidade de líquido pericapsular, 3 com granuloma capsular, 1 seroma tardio com conteúdo hemorrágico,1 rotura intra e extracapsular, 1 nódulo junto à cápsula fibrosa do implante, 2 linfonodopatia axilar ipsilateral, 1 silicone intralinfonodal, 1 edema do músculo peitoral, 2 tumor desmoide e 1 herniação da cápsula fibrosa. Conclusão: Estima-se que existam 50 milhões de mulheres com próteses de mama no mundo. Com base nesse dado, o número de complicações ditas "não usuais" passa a ser um desafio diagnóstico para o cirurgião plástico e o radiologista.

Introduction: Breast prosthesis implantation is one of the most performed surgeries in the world. Over time, different materials were used to reconstitute breast volume. Despite technical and surgical improvements and the safety of current implants, patients are faced with potential "unusual" complications: intracapsular and extracapsular ruptures, late hematomas and contour deformity, intra-nodal silicone, or herniation of the fibrous capsule. Magnetic resonance imaging (MRI) is the most useful imaging modality for investigating these complications. Method: This is a series of cases in which so-called "unusual" changes were reported, due to their low frequency or lack of mention in the literature, after surgeries to include a silicone prosthesis. The data were collected from the personal experience of one of the authors in his private clinic, in the city of Brasília-DF, between April 2015 and March 2023. Results: A total of 211 patients were evaluated, and less frequent changes were found in the MRI of 12 patients (5.68%), of which: 5 with a large amount of pericapsular fluid, 3 with capsular granuloma, 1 late seroma with hemorrhagic content, 1 intra and extracapsular rupture, 1 nodule close to the implant's fibrous capsule, 2 axillary lymph node disease ipsilateral, 1 intra-nodal silicone, 1 pectoral muscle edema, 2 desmoid tumor and 1 herniation of the fibrous capsule. Conclusion: It is estimated that there are 50 million women with breast implants in the world. Based on this data, the number of so-called "unusual" complications becomes a diagnostic challenge for the plastic surgeon and radiologist.

Outcomes after elevation of serratus anterior fascia flap versus serratus muscle flap in direct-to-implant breast reconstruction following mastectomy: a prospective study.

Objective: The purpose of this study was to compare postoperative pain between SF flap and serratus anterior muscle (SM) in direct-to-implant breast reconstruction. Methods: This is a prospective cohort study that included 53 women diagnosed with breast cancer who underwent mastectomy and one-stage implant-based breast reconstruction from January 2020 to March 2021. Twenty-nine patients (54.7%) had SF elevation, and 24 patients (45.3%) underwent SM elevation. We evaluated patient-reported early postoperative pain on the first day after surgery. Also, it was reported that all surgical complications in the first month and patient reported outcomes (PROs) were measured with the BRECON 23 questionnaire. Results: The serratus fascia group used implants with larger volumes, 407.6 ± 98.9 cc (p < 0.01). There was no significant difference between the fascial and muscular groups regarding the postoperative pain score reported by the patients (2 versus 3; p = 0.30). Also, there was no difference between the groups regarding early surgical complications and PROs after breast reconstruction. Conclusion: The use of SF seems to cause less morbidity, which makes the technique an alternative to be considered in breast reconstruction. Although there was no statistical difference in postoperative pain scores between the fascia and serratus muscle groups.

Unraveling Drug Delivery from Cyclodextrin Polymer-Coated Breast Implants: Integrating a Unidirectional Diffusion Mathematical Model with COMSOL Simulations.

Breast cancer ranks among the most commonly diagnosed cancers worldwide and bears the highest mortality rate. As an integral component of cancer treatment, mastectomy entails the complete removal of the affected breast. Typically, breast reconstruction, involving the use of silicone implants (augmentation mammaplasty), is employed to address the aftermath of mastectomy. To mitigate postoperative risks associated with mammaplasty, such as capsular contracture or bacterial infections, the functionalization of breast implants with coatings of cyclodextrin polymers as drug delivery systems represents an excellent alternative. In this context, our work focuses on the application of a mathematical model for simulating drug release from breast implants coated with cyclodextrin polymers. The proposed model considers a unidirectional diffusion process following Fick's second law, which was solved using the orthogonal collocation method, a numerical technique employed to approximate solutions for ordinary and partial differential equations. We conducted simulations to obtain release profiles for three therapeutic molecules: pirfenidone, used for preventing capsular contracture; rose Bengal, an anticancer agent; and the antimicrobial peptide KR-12. Furthermore, we calculated the diffusion profiles of these drugs through the cyclodextrin polymers, determining parameters related to diffusivity, solute solid-liquid partition coefficients, and the Sherwood number. Finally, integrating these parameters in COMSOL multiphysics simulations, the unidirectional diffusion mathematical model was validated.

Explante de silicone: a importância da ressonância nuclear magnética das mamas no planejamento préoperatório / Silicone explant: the importance of breast magnetic resonance imaging in preoperative planning

Introdução: A recente preocupação sobre a segurança dos implantes de silicone tem levado muitas mulheres a buscarem a retirada de seus implantes, mesmo sem aparente complicação nas mamas. Por outro lado, muitos cirurgiões não se sentem confortáveis em realizar o explante por receio de que a paciente não gostará do resultado estético após a cirurgia. A ressonância nuclear magnética (RNM) é um recurso valioso para avaliação diagnóstica das mamas e pode ser usada no planejamento do explante. O objetivo é demonstrar como a análise sistematizada das imagens da ressonância magnética das mamas pode auxiliar no planejamento do explante de silicone. Método: Uma análise detalhada dos cortes axial e sagital da RNM foi feita para avaliar a quantidade de tecido em cada mama. Essas imagens foram apresentadas às pacientes durante a consulta pré-operatória para que elas pudessem perceber, com clareza, o quanto o implante influencia no tamanho de suas mamas. No mesmo momento, foram apresentadas fotos de pós-operatório de pacientes com características semelhantes para que a paciente pudesse analisar, de forma mais objetiva, se ficaria satisfeita ou não com a estética das mamas após o explante. Resultados: As pacientes demonstraram alto grau de compreensão das imagens apresentadas e se mostraram satisfeitas com esta análise detalhada de expectativa de resultado. Conclusão: A comparação das imagens da RNM das mamas e das imagens de resultados de pós-operatório confere maior objetividade ao diálogo pré-operatório, favorecendo a compreensão do resultado esperado e trazendo maior clareza à decisão pelo explante.

Introduction: Recent concerns about the safety of silicone implants have led many women to seek the removal of their implants, even without apparent breast complications. On the other hand, many surgeons do not feel comfortable performing the explant for fear that the patient will not like the aesthetic result after surgery. Magnetic resonance imaging (MRI) is a valuable resource for diagnostic evaluation of the breast and can be used in explant planning. The objective is to demonstrate how the systematic analysis of breast MRI images can assist in planning silicone explantation. Method: A detailed analysis of the axial and sagittal MRI sections was performed to assess the amount of tissue in each breast. These images were presented to patients during the preoperative consultation so that they could clearly understand how much the implant influences the size of their breasts. At the same time, post-operative photos of patients with similar characteristics were presented so that the patient could analyze, more objectively, whether or not she would be satisfied with the aesthetics of her breasts after explantation. Results: The patients demonstrated a high degree of understanding of the images presented and were satisfied with this detailed analysis of expected results. Conclusion: The comparison of breast MRI images and postoperative results images provides greater objectivity to the preoperative dialogue, favoring the understanding of the expected result and bringing greater clarity to the decision for explantation.

Evaluation of conventional IMRT and VMAT strategies for postmastectomy radiation therapy after immediate implant-based reconstruction using the new ESTRO-ACROP contouring guidelines.

This study evaluated the usability of conventional templates based on the new contour guidelines of the European Society of Radiation and Oncology and Advisory Committee in Radiation Oncology Practice (ESTRO-ACROP) for treatment plans of postmastectomy radiotherapy after immediate implant-based reconstruction. Intensity-modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) plans generated with two different treatment planning systems (TPSs, Eclipse and Monaco) were examined. Six computed tomography scans of patients aged 35-54 years were retrospectively analysed who had undergone mastectomy and breast reconstruction using silicone implants after being diagnosed with left breast cancer. Six radiation oncologists participated in this study, and each of them contoured the target volume of one left breast using conventional contour (CTV-CONV) and new contour (CTV-ESTRO) methods. This study showed that compared with CTV-CONV, using CTV-ESTRO with objectives and cost functions similar to those of TPSs worsened the target volume coverage and increased the total number of monitor units. Considering the organs at risk, CTV-ESTRO tended to increase the mean dose delivered to the contralateral lung. It is concluded that the approach used for the new ESTRO-ACROP contour method cannot be applied in a manner similar to that for the conventional breast contour method, implying that the new ESTRO-ACROP contour method may require more time for improving plans for a given treatment.

Conclusion: The use of SF seems to cause less morbidity, which makes the technique an alternative to be considered in breast reconstruction. Although there was no statistical difference in postoperative pain scores between the fascia and serratus muscle groups.

Immediate prepectoral versus submuscular breast reconstruction in nipple-sparing mastectomy: a retrospective cohort analysis

Abstract Objective To evaluate early complications in prepectoral breast reconstruction. Methods A retrospective cohort study including 180 consecutive cases of nipple-sparing mastectomy, comparing immediate breast reconstruction with subpectoral to prepectoral mammary implants in 2012-2022. Clinical and demographic characteristics and complications in the first three months following surgery were compared between the two techniques. Results The prepectoral technique was used in 22 cases (12.2%) and the subpectoral in 158 (87.8%). Median age was higher in the prepectoral group (47 versus 43.8 years; p=0.038), as was body mass index (25.1 versus 23.8; p=0.002) and implant volume (447.5 versus 409 cc; p=0.001). The prepectoral technique was more associated with an inframammary fold (IMF) incision (19 cases, 86.4% versus 85, 53.8%) than with periareolar incisions (3 cases, 13.6% versus 73, 46.2%); (p=0.004).

The clinical and demographic characteristics differed between the techniques. Randomized clinical trials are required.

Experimental protocol for evaluation of biomaterials in an in-vivo silicone implant coverage

Purpose: To describe an experimental surgical model in rats using a dual-plane technique for evaluation of biomaterials in an in-vivo silicone implant coverage. Methods: This study was developed following the ISO 10993-6 standard. In this study, 40 male Wistar rats weighing between 250 and 350 g were used, distributed into two groups: experimental, biomaterial superimposed on the minimammary prosthesis (MP); and control, MP without implantation of the biomaterial, with eight animals at each biological point: 1, 2, 4, 12, and 26 weeks. Thus, at the end of biological points (1, 2, 4, 12, and 26 weeks; n = 8 animals per week), the tissue specimens achieved were fixed in buffered formalin and stained with hematoxylin-eosin. Results: Macroscopically, throughout the study, no postoperative complications were apparent. In the histological analysis, it was possible to observe the evolution of the inflammatory response, tissue repair, and fibrous capsule during the biological points. Conclusions: The experimental model described in this study proved to be suitable for evaluating the biomaterial used in the coverage of breast silicone implants.

Fatores de risco consequentes a complicações no pósoperatório da mastoplastia de aumento primária com implantes de silicone: Estudo retrospectivo / Risk factors resulting from complications in the postoperative period of primary breast augmentation with silicone implants: Retrospective study

Introdução: A mamoplastia de aumento é uma das cirurgias plásticas mais realizadas no mundo. Tendo em vista sua alta aplicabilidade, é fundamental conhecer os fatores de risco relacionados à incidência de complicações pós-operatórias a fim de reduzilas nesse tipo de procedimento. Método: Este estudo é retrospectivo feito por meio da análise dos prontuários de 76 pacientes que realizaram mamoplastia de aumento primária com implantes de silicone durante os meses de janeiro de 2018 a dezembro de 2020. Resultados: Observou-se que a presença de comorbidades aumentou a incidência de complicações pós-operatórias precoces (p<0,001), mas não de complicações pósoperatórias tardias (p=0,8). O maior tempo cirúrgico também aumentou a incidência de complicações pós-operatórias (p=0,005). Conclusão: A presença de comorbidades influencia diretamente na incidência de complicações pós-operatórias da mastoplastia de aumento e por esta razão deve-se realizar uma adequada compensação pré-operatória antes de submeter as pacientes a este procedimento cirúrgico.

Introduction: Breast augmentation is one of the most performed plastic surgeries in the world. Given its high applicability, it is essential to know the risk factors related to the incidence of postoperative complications to reduce them in this type of procedure. Method: This retrospective study analyzed the medical records of 76 patients who underwent primary breast augmentation with silicone implants from January 2018 to December 2020. Results: It was observed that the presence of comorbidities increased the incidence of early postoperative complications (p<0.001) but not of late postoperative complications (p=0.8). Longer surgical time also increased the incidence of postoperative complications (p=0.005). Conclusion: The presence of comorbidities directly influences the incidence of postoperative complications after breast augmentation, and for this reason, adequate preoperative compensation must be carried out before submitting patients to this surgical procedure.

Functionalization of breast implants by cyclodextrin in-situ polymerization: a local drug delivery system for augmentation mammaplasty.

Mammaplasty is a widely performed surgical procedure worldwide, utilized for breast reconstruction, in the context of breast cancer treatment, and aesthetic purposes. To enhance post-operative outcomes and reduce risks (hematoma with required evacuation, capsular contracture, implant-associated infection and others), the controlled release of medicaments can be achieved using drug delivery systems based on cyclodextrins (CDs). In this study, our objective was to functionalize commercially available silicone breast implants with smooth and textured surfaces through in-situ polymerization of two CDs: ß-CD/citric acid and 2-hydroxypropyl-ß-CD/citric acid. This functionalization serves as a local drug delivery system for the controlled release of therapeutic molecules that potentially can be a preventive treatment for post-operative complications in mammaplasty interventions. Initially, we evaluated the pre-treatment of sample surfaces with O2 plasma, followed by chitosan grafting. Subsequently, in-situ polymerization using both types of CDs was performed on implants. The results demonstrated that the proposed pre-treatment significantly increased the polymerization yield. The functionalized samples were characterized using microscopic and physicochemical techniques. To evaluate the efficacy of the proposed system for controlled drug delivery in augmentation mammaplasty, three different molecules were utilized: pirfenidone (PFD) for capsular contracture prevention, Rose Bengal (RB) as anticancer agent, and KR-12 peptide (KR-12) to prevent bacterial infection. The release kinetics of PFD, RB, and KR-12 were analyzed using the Korsmeyer-Peppas and monolithic solution mathematical models to identify the respective delivery mechanisms. The antibacterial effect of KR-12 was assessed against Staphylococcus epidermidis and Pseudomonas aeruginosa, revealing that the antibacterial rate of functionalized samples loaded with KR-12 was dependent on the diffusion coefficients. Finally, due to the immunomodulatory properties of KR-12 peptide on epithelial cells, this type of cells was employed to investigate the cytotoxicity of the functionalized samples. These assays confirmed the superior properties of functionalized samples compared to unprotected implants.

Breast implant-associated anaplastic large cell lymphoma presenting as a breast mass: A case report and literature review.

INTRODUCTION: Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare neoplasm most frequently associated with textured implant placement. The classic presentation consists of a persistent periprosthetic seroma. Implant removal and individualized adjuvant treatment are potentially curative interventions. Most BIA-ALCL present with a seroma, not with a breast and/or axillary mass. Knowledge of this presentation and how to manage it allows an adequate diagnosis, and appropriate treatment with excellent results. PRESENTATION OF CASE: A 44-year-old woman presented with a 3-month history of a right breast mass located in the lower medial quadrant, with associated right axillary lymphadenopathy. Medical history was significant for a mastoplasty with textured implants 15 years before the onset of her symptoms. Imaging studies and histological analysis helped to confirm the diagnosis of BIA-ALCL. A bilateral capsulectomy was performed and adjuvant chemotherapy and immunotherapy were administered. With these interventions, the patient had complete resolution of her symptoms, good cosmetic results, and absence of tumor activity detectable by positron emission tomography with fluorodeoxyglucose (PET-CT FDG) at a 2.5-year follow-up. DISCUSSION: This case describes an atypical presentation of BIA-ALCL as a breast mass, as well as lymph node and bone marrow involvement. Knowledge of the different presentation modalities of this pathology is necessary for a correct diagnosis and treatment. Through a multidisciplinary approach, adequate treatment was given with excellent results. CONCLUSION: Anaplastic large cell lymphoma associated with breast implants is a clinicopathological entity still little known in some medical fields. A variety of presentations must be considered, and high clinical suspicion must be maintained in patients with a history of textured breast implant placement to optimize diagnosis and avoid delays in treatment.

Linfoma anaplásico de células gigantes asociado a implantes mamarios, una enfermedad desconocida / Breast implant-associated anaplastic large cell lymphoma, an unknown disease

Resumen Existe un gran número de enfermedades del tejido mamario que tienen patrones radiológicos específicos y hallazgos imagenológicos concretos. No obstante, el linfoma anaplásico de células gigantes asociado a implantes mamarios (LACG-AIM) es una enfermedad con hallazgos poco específicos que ha presentado un aumento en su incidencia debido al crecimiento exponencial de la mamoplastia de aumento a lo largo de los años en todo el mundo, así como al uso de implantes tanto en cirugía estética como reconstructiva. En este artículo se realiza una revisión de la epidemiología, etiología, fisiopatología y diagnóstico del LACG-AIM. Se plantean hallazgos radiológicos sugestivos de esta enfermedad, lo que permite al radiólogo aportar información al equipo tratante para el diagnóstico y la planificación quirúrgica en caso de ser necesario.

Abstract There are many diseases related to breast tissue that have specific radiological patterns and imaging findings. However, anaplastic large cell lymphoma associated with breast implants is a condition with nonspecific findings that has an increased incidence due to the exponential growth worldwide of augmentation mammoplasty over the years and the use of implants in aesthetic and reconstructive surgery. In this article, a review of the epidemiology, etiology, pathophysiology, and diagnosis of this disease is carried out, highlighting radiological findings suggestive of this disease, which allows the radiologist to provide information to the treating team for diagnosis and surgical planning if necessary.

ASIA and BIA-ALCL as adverse reactions to silicone breast implants / ASIA e BIA-ALCL como reações adversas aos implantes mamários de silicone

Adjuvant-induced autoimmune/inflammatory syndrome leads to capsular contracture and fibrosis from the oxidation that takes place in silicone. Anaplastic large cell lymphoma occurs through the development of a seroma, with the formation of a periprosthetic effusion, or through the infiltration of the condition itself. To analyze these conditions, a review of the literature was carried out on the symptoms and pathophysiology of the autoimmune/inflammatory syndrome induced by adjuvants and anaplastic large cell lymphoma, searched using the terms "ASIA breast silicone," "Lymphoma," "Adjuvants" "Immunologic" " Breast Implants" on the PubMed platform. Analyzing the data obtained, it was noted that the symptoms of the autoimmune/inflammatory syndrome induced by adjuvants are nonspecific, such as fatigue, myalgia, arthralgia, morning stiffness, and night sweats, and therefore need attention. Anaplastic large cell lymphoma presents with breast pain, periprosthetic effusion, and palpable mass, among other characteristics. Because of these aspects, it is concluded that a good investigation should be carried out when nonspecific symptoms appear, regardless of the time the surgery was performed since these complications can occur years later.

A síndrome autoimune/inflamatória induzida por adjuvantes leva à contratura capsular e fibrose pela oxidação que acontece no silicone. O linfoma anaplásico de grandes células ocorre através do desenvolvimento de um seroma, com a formação de derrame periprotético ou por uma infiltração da própria afecção. Para análise destes acometimentos, foi realizada uma revisão da literatura acerca da sintomatologia e fisiopatologia da síndrome autoimune/inflamatória induzida por adjuvantes e linfoma anaplásico de grandes células, pesquisada através dos termos "ASIA breast silicone" "Lymphoma" "Adjuvants" "Immunologic" "Breast Implants" na plataforma PubMed. Analisando os dados obtidos, notou-se que os sintomas da síndrome autoimune/inflamatória induzida por adjuvantes são inespecíficos, como fadiga, mialgia, artralgia, rigidez matinal e suores noturnos, e, portanto, necessitam de atenção. Já o linfoma anaplásico de grandes células se apresenta com dor mamária, derrame periprotético, massa palpável, dentre outras características. Em vista destes aspectos, conclui-se que uma boa investigação deve ser realizada ao surgirem sintomas inespecíficos, independentemente do tempo que a cirurgia foi realizada, uma vez que estas complicações podem ocorrer anos após a cirurgia.

Milky secretion after late breast reconstruction with latissimus dorsi musculocutaneous flap with implant / Produção de secreção leitosa após reconstrução mamária tardia com retalho musculocutâneo de latíssimo do dorso com implante

We present a rare case of a 28-year-old patient with invasive ductal carcinoma who underwent neoadjuvant chemotherapy, modified radical mastectomy, radiotherapy, and late breast reconstruction with latissimus dorsi flap associated with the implant. One year later, she underwent reconstruction of the nipple-areola complex over the cutaneous island of the latissimus dorsi flap with a total skin graft from the thigh and graft from the caudal portion of the contralateral papilla. She became pregnant six months after the reconstruction of the nipple-areola complex and, unexpectedly, presented milk production by the reconstructed breast.

Apresentamos um caso raro de uma paciente de 28 anos com carcinoma ductal invasivo submetida a quimioterapia neoadjuvante, mastectomia radical modificada, radioterapia e reconstrução mamária tardia com retalho de latíssimo do dorso associado a implante. Um ano depois, foi submetida a reconstrução do complexo areolopapilar sobre a ilha cutânea do retalho do grande dorsal com enxerto de pele total da coxa e enxerto da porção caudal da papila contralateral. Ela engravidou seis meses após a reconstrução do complexo areolopapilar e, inesperadamente, apresentou produção de leite pela mama reconstruída.

[Autoimmune/inflammatory syndrome induced by adjuvants. Case report]. / Síndrome autoinmunitario/inflamatorio inducido por adyuvantes. Reporte de caso.

Background: The indiscriminate application of substances for aesthetic purposes, such as silicone in breast implants, leads to the production of common local signs such as inflammation, skin irregularities, edema, erythema, vascular neoformations, and ulcers, which can evolve into general symptoms such as fever, asthenia, weakness, arthralgia or activate the immune system abnormally, causing the appearance of autoimmune diseases. This set of signs and symptoms is called adjuvant-induced autoimmune/inflammatory syndrome. Clinical case: We present the case of a 50-year-old woman with a history of silicone-based breast implants who spontaneously developed a hemorrhagic coagulopathy, type A acquired hemophilia was documented, that is, autoantibodies against coagulation factor VIII. Thanks to the work of a multidisciplinary team, it is possible to successfully diagnose and treat the patient with bridging agents, implant removal and management of associated symptoms. Conclusion: the importance of knowing the pathology is recognized, which, although it is rare, when it occurs has a high mortality rate if it is not diagnosed and treated on time.

Introducción: la aplicación de sustancias con fines estéticos de forma indiscriminada, como es el caso de la silicona en los implantes mamarios, llevan a la producción de signos locales comunes como: inflamación, irregularidad en la piel, edema, eritema, neoformaciones vasculares y úlceras, que pueden evolucionar a síntomas generales como la fiebre, astenia, adinamia, artralgias o a activar, de manera anómala, el sistema inmunitario, causando la aparición de enfermedades autoinmunitarias. A este conjunto de signos y síntomas se le denomina síndrome autoinmunitario/inflamatorio inducido por adyuvantes. Caso clínico: presentamos el caso de una mujer de 50 años con antecedente de implantes mamarios a base de silicona que desarrolla, de manera espontánea, una coagulopatía hemorrágica, se documenta hemofilia tipo A adquirida, es decir, autoanticuerpos contra el factor VIII de la coagulación. Gracias al trabajo de un equipo multidisciplinario se consigue diagnosticar y tratar de manera exitosa a la paciente con agentes de puente, remoción de los implantes y manejo de los síntomas asociados. Conclusión: se reconoce la importancia de conocer la patología que, si bien es rara, cuando se presenta tiene alta tasa de mortalidad si no se diagnostica y trata a tiempo.

Increase in the volume of the breast implant by passing organic material into it / Aumento do volume do implante mamário por passagem de material orgânico para seu interior

Introduction: The search for an anatomical substitute for the breast, for the purpose of correcting aesthetic problems has a long history of failure until the arrival of silicone. Since the beginning of its use, in the 1960s, many complications have appeared, such as infection, rejection, rupture, in addition to silicone leakage. We did not find in the literature, however, any report on the passage of materials from the human organism to the interior of implants. The objective is to identification by infrared spectrophotometry (FTIR) and clinical analysis, reporting the passage of organic substances into breast implants without any violation of their capsule. Methods: 1500 pairs of breast implants were analyzed, surgically removed from 1998 to 2018. Of which six were included in the study. Results: Three materials were analyzed showing macroscopic changes in their interior, without violating the capsule. A second sample was performed on a similar implant, but without use. The third material was a sample of fatty breast tissue removed from the patient during the surgery. Materials compatible with fat, animal protein and hemoglobin were found inside the implant. Conclusions: The change evidenced in the material inside the two implants indicates the occurrence of the passage of organic materials through an intact capsule.

Introdução: A busca de um substituto anatômico para a mama, para fins de correção de problemas estéticos, tem longa história de insucessos até a chegada do silicone. Desde o início de seu uso, na década de 1960, muitas complicações surgiram, como infecção, rejeição, rotura, além do extravasamento de silicone. Não encontramos na literatura, porém, relato algum sobre a passagem de materiais do organismo humano para o interior de implantes. O objetivo é a identificação por espectrofotometria de infravermelho (FTIR) e análise clínica, relatando a passagem de substâncias orgânicas para o interior de implantes mamários sem que os mesmos apresentem violação qualquer de sua cápsula. Método: Foram analisados 1500 pares de implantes mamários, removidos cirurgicamente no período de 1998 a 2018. Destes, seis foram encaminhados incluídos no estudo. Resultados: Foram analisados três materiais apresentando alterações macroscópicas em seu interior, sem que houvesse violação da cápsula. Uma segunda amostra foi realizada em implante semelhante, porém sem uso. O terceiro material foi uma amostra de tecido gorduroso mamário removido da própria paciente durante o ato cirúrgico. Foram encontrados materiais compatíveis com gordura, proteína animal e hemoglobina no interior do implante. Conclusões: A alteração evidenciada no material do interior dos dois implantes nos indica a ocorrência de passagem de materiais orgânicos através de cápsula intacta.
