    Fibromatosis refers to an extra-abdominal desmoid tumor or aggressive fibromatosis. Breast fibromatosis can develop in association with the capsule around a breast implant, although reports of cases of fibromatosis associated with breast implants are rare. As the demand for breast augmentation has increased, it is important to understand the diseases associated with breast implants. In the present report, we describe a case of breast fibromatosis that developed adjacent to a breast implant and demonstrated a relatively well-defined border even though it invaded the surrounding structures. We also explore the specific imaging features for diagnosing breast fibromatosis in association with implants by reviewing previous literature.

    Objective Since Helms' successful bilateral cochlear implantation with good results in 1996, there have been increasing number of reports on bilateral cochlear implantation. Most second device have been implantated within one year after the first. Considering effects of long time auditory deprivation, it is not clear whether a delayed second cochlear implant serves to add additional benefits and how it may interact with central nervous system plasticity. Methods Three cases who received delayed second cochlear implants at People's Hospital of Peking University from 2002 to 2005 were reviewed. The interval between the first and second implants was longer than 2 years in all three patients. Sound perception, and unilateral/bilateral speech discrimination in quiet and noise were evaluated. In addition, GAP detection test was conducted in one patient. Results In one case,having both implants on provided improved performance compared to using only one implant both in quiet and noise. Presumably due to visual interference from lip-reading or short interval between second implant and testing,one patient showed no improvement from using the second implant either in quiet or noise, while the last case demonstrated additional benefits from the second implant only in quiet. In all three patients, performance in recognizing the four tones in Mandarin was superior over word recognition. Conclusions Considerable plasticity in the cerebral auditory center is preserved, despite long acoustic deprivation in some children who have received unilateral cochlear implant. Delayed second implants can result in significant improvements in some of these children. Visual interference from lip-reading may be an obstacle during retraining. The better recognition of tones in the Mandarin language may represent a different sound discrimination mechanism in the auditory system,although it may also be related to the signal processing mechanisms of the implant used (MED-EL COMBI 40+).

    Full Text Available BackgroundIn 2012, a new anatomic breast implant of form-stable silicone gel was introduced onto the Korean market. The intended use of this implant is in the area of aesthetic breast surgery, and many reports are promising. Thus far, however, there have been no reports on the use of this implant for breast reconstruction in Korea. We used this breast implant in breast reconstruction surgery and report our early experience.MethodsFrom November 2012 to April 2013, the Natrelle Style 410 form-stable anatomically shaped cohesive silicone gel-filled breast implant was used in 31 breasts of 30 patients for implant breast reconstruction with an acellular dermal matrix. Patients were treated with skin-sparing mastectomies followed by immediate breast reconstruction.ResultsThe mean breast resection volume was 240 mL (range, 83-540 mL. The mean size of the breast implants was 217 mL (range, 125-395 mL. Breast shape outcomes were considered acceptable. Infection and skin thinning occurred in one patient each, and hematoma and seroma did not occur. Three cases of wound dehiscence occurred, one requiring surgical intervention, while the others healed with conservative treatment in one month. Rippling did not occur. So far, complications such as capsular contracture and malrotation of breast implant have not yet arisen.ConclusionsBy using anatomic breast implants in breast reconstruction, we achieved satisfactory results with aesthetics better than those obtained with round breast implants. Therefore, we concluded that the anatomical implant is suitable for breast reconstruction.

    The purpose of this study is to assess the usefulness of MRI in the preoperative diagnosis of breast implant-related complications. Thirty four breast implants in 17 patients were examined. Eight breasts had a history of repeated surgery due to rupture and in eight others, simultaneous interstitial silicone injection had been performed. MR images of the 34 implants were prospectively analyzed for implant-related complications, without prior clinical information, and the findings were compared with the results of surgery. MRI was an effective and useful method for the preoperative evaluation of implant-related complications; degree of contracture was successfully predicted. (author). 18 refs., 2 tabs., 5 figs.

    About 1 in 300 women in the Netherlands has a breast implant but many patients do not know what type of implant was inserted. The quality of breast implants is currently monitored by the implant manufacturers. Sufficient incidents have occurred to show that an independent registry is required to measure the quality of breast implants and to facilitate a national recall, if necessary. Good national and international collaboration with the government, the manufacturers and other specialist associations is crucial for setting up an implant registry. Since April 2015, data about patients and their implants have been collected, independently and prospectively, in the Dutch Breast Implant Registry to increase patient safety in cases of breast implant surgery in the Netherlands.

    Newspaper coverage of the silicone breast implant controversy from 1992 through 1996 was analyzed to determine whether women in the United States were provided with a fair and balanced account. The paper also addressed whether or not Dow Corning's public relations campaign impacted newspaper coverage. All stories from the New York Times, the Chicago Tribune and the Wall Street Journal were analyzed. Findings suggested that early coverage of the controversy focused on the health risks of silicone breast implants while later coverage focused on the financial situations of the implant manufacturers. The most-interviewed sources were spokespersons for the implant manufacturers, while the least-interviewed sources were women with implants. The findings suggested that reporting patterns were influenced by the public relations efforts of the implant manufacturer, raising questions concerning the coverage of health care controversies involving large corporations seeking refuge from litigation.

    2016-01-01

    Full Text Available The number of women undergoing breast implant procedures is increasing exponentially. It is, therefore, imperative for a radiologist to be familiar with the normal and abnormal imaging appearances of common breast implants. Diagnostic imaging studies such as mammography, ultrasonography, and magnetic resonance imaging are used to evaluate implant integrity, detect abnormalities of the implant and its surrounding capsule, and detect breast conditions unrelated to implants. Magnetic resonance imaging of silicone breast implants, with its high sensitivity and specificity for detecting implant rupture, is the most reliable modality to asses implant integrity. Whichever imaging modality is used, the overall aim of imaging breast implants is to provide the pertinent information about implant integrity, detect implant failures, and to detect breast conditions unrelated to the implants, such as cancer.

  8. Silicone breast implants and immune disease.

    Science.gov (United States)

    Shons, A R; Schubert, W

    1992-05-01

    Silicone was originally regarded as inert in the human body. Silicone medical devices have been associated with various complications that may involve an immune reaction to silicone or a silicone organic complex. There have been more than 80 cases reported in the medical literature of a varied systemic autoimmune illness in patients who have had various foreign materials placed in the breast. Controversy exists as to which complications have a cause and effect relationship, and which represent coincidental findings. It is difficult to distinguish between nonspecific local reactions and reactions that have an immunological basis. Approximately 1,000,000 to 2,000,000 women in the United States have had silicone breast implants inserted for reconstruction or augmentation mammaplasty; 28 of those patients have been reported to have developed a systemic autoimmune disease. Data on the 28 reported cases do not in any way prove a causal relationship between breast implants and immune disease. Given the natural incidence of autoimmune diseases, we would expect a coincidental occurrence in the United States of more than 1,000 cases of autoimmune disease in women who had undergone breast implant surgery. Additional information must be obtained to resolve the question. The true incidence of autoimmune disease in patients with implants needs to be determined. A prospective registry of implant patients should be established and comprehensive retrospective information obtained on the implant patient population. Further experimental work is necessary on the bioreactivity of silicone. Patients with implants and autoimmune disease, once identified, must be carefully evaluated by physicians who are experienced in the treatment of autoimmune disease.

    Rosich-Medina, Anais; Wang, Susan; Erel, Ertan; Malata, Charles M.

    2013-01-01

    Objective: The internal mammary vessels are a popular recipient site for microsurgical anastomoses of free flap breast reconstructions. We, however, observed 3 patients undergoing internal mammary vessel delayed free flap breast reconstruction that subsequently developed tumor recurrence at this site. We reviewed their characteristics to determine whether there was a correlation between delayed microsurgical reconstruction and local recurrence. Methods: A retrospective review of a single surgeon's delayed free flap breast reconstructions using the internal mammary vessels was conducted over a 7-year period to identify the time intervals between mastectomy and delayed breast reconstruction and between delayed breast reconstruction and recurrence. Results: Three patients developed local recurrence at the site of the microvascular anastomoses following delayed breast reconstruction. All patients had been disease-free following mastectomy. The median time interval between mastectomy and delayed breast reconstruction was 28 months (range = 20-120 months) while that between delayed breast reconstruction and local recurrence was 7 months (range = 4-10 months). Two patients died from metastatic disease, 36 and 72 months following their local recurrence. One patient remains alive 44 months after reconstruction. Conclusions: Local tumor recurrence at the internal mammary vessel dissection site following delayed breast reconstruction raises the question whether these 2 events may be related. Specifically, could internal mammary vessel dissection undertaken for delayed microsurgical reconstruction predispose to recurrence in the internal mammary lymph nodes? Further research is needed to ascertain whether delayed breast reconstruction increases the risk of local recurrence in this patient group. PMID:23383360

    AIM: To demonstrate the magnetic resonance imaging (MRI) appearances of intact and ruptured Trilucent TM implants with imaging and surgical correlation. The appearances of the implant transponder artefact are also described MATERIALS AND METHODS: A retrospective review of the MRI findings in 34 patients with bilateral subpectoral Trilucent TM breast implants (Lipomatrix, Inc./Collagen Aesthetics International Inc., Neuchatel, Switzerland) was performed. Patients under implant surveillance and those with suspected implant rupture formed the study group. Imaging findings were correlated with surgical appearances. RESULTS: Surgical correlation was available in 53% of patients. Fifty per cent (18/36) of implants were intact at surgery, 50% (18/36) of implants were ruptured. Of the 18 ruptured implants, 17 were intracapsular ruptures and one an extracapsular rupture. The sensitivity of MRI for detection of intracapsular rupture in Trilucent TM breast implants was 82% specificity 76%, positive predictive value 78%, negative predictive value 81% and accuracy 79% in this study group. No case of implant rupture was obscured by the transponder artefact. Four implants were found to have 'pseudocapsules' at surgery (5{center_dot}9%), the implants were intact with fluid present between the implant and capsule. Only one pseudocapsule was demonstrated on MRI. CONCLUSION: Magnetic resonance imaging is currently the most accurate technique for diagnosis of implant rupture in Trilucent TM breast implants. Transponder artefact does not appear to interfere with the assessment of implant rupture. Elson, E. M. et al. (2002)

    2013-05-01

    It has been hypothesized that bacterial biofilms on breast implants may cause chronic inflammation leading to capsular contracture. The association between bacterial biofilms of removed implants and capsular contracture was investigated. Breast implants explanted between 2006 and 2010 at five participating centres for plastic and reconstructive surgery were investigated by sonication. Bacterial cultures derived from sonication were correlated with patient, surgical and implant characteristics, and the degree of capsular contracture. The study included 121 breast implants from 84 patients, of which 119 originated from women and two from men undergoing gender reassignment. Some 50 breast prostheses were implanted for reconstruction, 48 for aesthetic reasons and 23 implants were used as temporary expander devices. The median indwelling time was 4·0 (range 0·1-32) years for permanent implants and 3 (range 1-6) months for temporary devices. Excluding nine implants with clinical signs of infection, sonication cultures were positive in 40 (45 per cent) of 89 permanent implants and in 12 (52 per cent) of 23 temporary devices. Analysis of permanent implants showed that a positive bacterial culture after sonication correlated with the degree of capsular contracture: Baker I, two of 11 implants; Baker II, two of ten; Baker III, nine of 23; and Baker IV, 27 of 45 (P contracture, indicating the potential causative role of bacterial biofilms in the pathogenesis of capsular contracture.

    Figus, Andrea; Canu, Vanessa; Iwuagwu, Fortune C; Ramakrishnan, Venkat

    2009-09-01

    Recent advances in breast reconstruction allow for high expectations regarding long-term symmetry and aesthetic appearance. The DIEP flap is currently considered as an ideal autologous reconstruction. However, there are situations in which the amount of tissue from a DIEP flap is not enough to achieve adequate symmetry. Indications and outcomes for a combined use of DIEP flap and implants are discussed in order to describe and examine a further scenario in optimising breast reconstruction. Between January 2004 and January 2006, all patients who underwent combined DIEP/implant breast reconstruction have been collected and followed prospectively. When clinical assessment demonstrated inadequate amount of tissue in the abdominal region to achieve a suitable unilateral or bilateral reconstruction with DIEP flaps, the patients were counselled about the opportunity of primary augmentation of the DIEP flaps. In cases where DIEP breast reconstruction has been done previously and there is a considerable asymmetry, delayed flap augmentation was considered. Patient's age, indication for surgery, preoperative and postoperative radiotherapy (RT), operative procedure, implant size, location and timing of insertion, complications, outcomes, and follow-up have been gathered. In all cases, textured round silicone gel implants have been used. After 12 months, four-point scales were used to analyse patients' satisfaction and aesthetic outcome. During the study period, 156 patients underwent breast reconstruction with 174 DIEP flaps. Fourteen patients (8.9%) had breast reconstruction with 19 DIEP flaps and 18 implants. The mean follow-up was 20.6 months (range 12-32 months). Fourteen implants were placed primarily at the time of DIEP reconstruction. The average implant weight was 167.2g with range between 100 and 230 g. Implant/flap weight ratio is about 1:5 corresponding to 20%. In six flaps, the patients had RT before the reconstruction, whilst in three cases of delayed DIEP flap

    This breast cancer is one of the most important death causes in women. Among the more frequently medical treatment for advanced breast cancer is the mastectomy. This situation leads to silicone implants as an esthetic option. There have been cases in patients with implants where cancer was frequently detected, in which a conventional radiotherapy is required. In this work is presented a study of the probable adverse effects caused by the application of high power X-rays (6-10 MV) to the silicone implants and to the surrounding tissues. In the research carried out at the clinic, none Bolus effect was detected in patients with implants. Our results prescribe that in the case of patients with implants and frequent breast cancer, the removal of implants is not necessary due radiotherapy works directly in the damaged tissues. (Author)

    BACKGROUND Despite current recommendations for women to be screened for breast cancer with mammography every one to two years, less than half of all newly diagnosed breast cancers are initially detected through screening mammography. Prompt medical attention to a new breast symptom can result in earlier stage at diagnosis, yet many patients delay seeking medical care after becoming aware of a breast symptom. METHODS In a population-based study of breast cancer we examined factors potentially associated with patient delay in seeking health care for a breast symptom among 436 symptomatic urban breast cancer patients (146 White, 197 Black and 95 Hispanic). Race/ethnicity, socioeconomic status, health care access and utilization, and misconceptions about the meaning of breast lumps were the key independent variables. RESULTS Sixteen percent of patients reported delaying more than 3 months before seeking medical advice about breast symptoms. Misconceptions about breast lumps, and lacking a regular provider, health insurance and recent preventive care were all associated with prolonged patient delay (p<0.005 for all). Misconceptions were much more common among ethnic minorities and women of lower socioeconomic status. CONCLUSION Reducing patient delay and disparities in delay will require both educating women about the importance of getting breast lumps evaluated in a timely manner, and providing greater access to regular health care.

  20. Versatility of Capsular Flaps in the Salvage of Exposed Breast Implants

    2015-03-01

    Full Text Available Summary: Breast implant exposure due to poor tissue coverage or previous irradiation represents a surgical challenge both in the reconstructive and aesthetic plastic surgery practice. In case of implant extrusion or incipient exposure, the commonly suggested strategies, such as targeted antibiotic therapy, drainage and lavage of the cavity, fistulectomy, and primary closure, may be ineffective leading the surgeon to an unwanted implant removal or to adopt more invasive flap coverage procedures. Breast implant capsule, in its physiological clinical behavior, can be considered as a new reliable source of tissue, which can be used in a wide range of clinical situations. In our hands, capsular flaps proved to be a versatile solution not only to treat breast contour deformities or inframammary fold malpositions but also to salvage exposed breast implants. In this scenario, the use of more invasive surgical techniques can be avoided or simply saved and delayed for future recurrences.(Plast Reconstr Surg Glob Open 2015;3:e340; doi:10.1097/GOX.0000000000000307; Published online 30 March 2015.

    We describe the case of a 46-year-old female patient treated for disseminated tuberculosis (TB) infection involving the lungs, urinary tract and skin. Following initiation of antituberculous therapy, the patient's right breast implant eroded through the overlying skin and was seen to be herniating through the resulting defect. The breast implant was removed under local anaesthetic and histological analysis of the resected tissue demonstrated granuloma formation consistent with periprosthetic TB. Wound healing following implant removal was poor and future breast augmentation surgery was only considered following completion of 12 months anti-TB treatment. This case constitutes the first report in the literature of percutaneous breast implant herniation resulting from periprosthetic infection with TB. A high index of suspicion is required to ensure early detection and timely management of TB and, in cases where periprosthetic pus aspirate is sterile, mycobacterial infection must be actively excluded. 2015 BMJ Publishing Group Ltd.

    Capsular contraction is a frequent complication following breast augmentation. On the other hand, capsular weakness, a not widely recognized complication, may occur around the implant. A weak capsule allows the migration of the prosthesis to the lateral region of the thoracic region or inferiorly, towards the abdomen, due to gravitational forces. The cause of capsular weakness remains unresolved. Implant malposition, with lateral or downward displacement, breast asymmetry, improper contour, w...

    The aging population, in combination with the popularity of breast augmentation with implants, presents surgeons with a growing number of cases involving women undergoing minimally invasive cardiac surgery (MICS) who have breast implants. We present an unusual complication involving the delayed migration of a subpectoral implant into the chest cavity through an iatrogenic defect after a minimally invasive mitral valve repair. This chest wall defect was ultimately repaired with a latissimus dorsi flap. Although MICS has been described in women with breast implants, the documented experience remains limited. Most authors classically recommend explantation of the prosthesis to provide access to the chest wall; however, some have later suggested preserving the implant capsule in situ while performing the cardiac procedure with gentle retraction. From our literature review and experience, we recommend that the posterior capsule should remain intact. If this is not possible, then the chest wall closure should be reinforced with either mesh, soft tissue, or both. Soft tissue options include the conversion from a subpectoral to a subglandular position to use the pectoralis major, or a latissimus dorsi muscle flap. With the increasing number of these cases along with the complexities of minimally invasive procedures, close communication and planning should be undertaken between both cardiothoracic and plastic surgeons when taking care of these patients. Above all, when faced with postoperative complications after MICS, the plastic surgeon must maintain a high index of clinical suspicion and consider the possibility of intrathoracic migration of an implant so that proper workup and planning may be initiated.

    Primary breast lymphoma is a rare disease and accounts for 0.5% of cases of breast cancer. Most primary breast lymphomas develop from B cells, and the involvement of T cells is rare. Anaplastic large cell lymphoma (ALCL) is a recently discovered T-cell lymphoma associated with breast implants. Only a few cases have been reported to date. It is believed that the incidence of ALCL is increasing because of the increasing number of breast implants. The clinical presentation is variable and can manifest as a palpable mass in the breast or armpit, breast pain, or capsular contracture. Because of the rarity of the disease and the lack of knowledge to date, clinical diagnosis is often delayed, with consequent delays in treatment. The cause and pathogenesis have not been fully elucidated, and there are no evidence-based guidelines for diagnosis, treatment, or follow-up of this disease. We present a review of cases of patients with silicone breast implants, including ALCL, a rare type of breast cancer that is still under study, and silicone-induced granuloma of breast implant capsule and its differential diagnosis, and discuss if a silicone-induced granuloma of breast implant capsule could be the precursor of the disease.

    The authors report a very rare case of necrobiosis lipoidica, histopathologically confirmed, which happened in the breast a few months following the insertion of a silicone implant (post-mastectomy reconstruction). This case raises two problems: the physiopathology (role of the silicone implant) and the treatment of this accident, resistant to current therapy.

    Few data are available concerning surgical site infection (SSI) and noninfectious wound complications (NIWCs) after delayed (DR) and secondary reconstruction (SR) compared with immediate reconstruction (IR) procedures in the breast. To compare the incidence of SSI and NIWCs after implant and autologous IR, DR, and SR breast procedures after mastectomy. This retrospective cohort study included women aged 18 to 64 years undergoing mastectomy from January 1, 2004, through December 31, 2011. Data were abstracted from a commercial insurer claims database in 12 states and analyzed from January 1, 2015, through February 7, 2017. Reconstruction within 7 days of mastectomy was considered immediate. Reconstruction more than 7 days after mastectomy was considered delayed if the mastectomy did not include IR or secondary if the mastectomy included IR. International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes for SSI and NIWCs. Mastectomy was performed in 17 293 women (mean [SD] age, 50.4 [8.5] years); 61.4% of women had IR or DR. Among patients undergoing implant reconstruction, the incidence of SSI was 8.9% (685 of 7655 women) for IR, 5.7% (21 of 369) for DR, and 3.2% (167 of 5150) for SR. Similar results were found for NIWCs. In contrast, the incidence of SSI was similar after autologous IR (9.8% [177 of 1799]), DR (13.9% [19 of 137]), and SR (11.6% [11 of 95]) procedures. Compared with women without an SSI after implant IR, women with an SSI after implant IR were significantly more likely to have another SSI (47 of 412 [11.4%] vs 131 of 4791 [2.7%]) and an NIWC (24 of 412 [5.8%] vs 120 of 4791 [2.5%]) after SR. The incidence of SSI (24 of 379 [6.3%] vs 152 of 5286 [2.9%]) and NIWC (22 of 379 [5.8%] vs 129 of 5286 [2.4%]) after implant SR was higher in women who had received adjuvant radiotherapy. Wound complications after IR were associated with significantly more breast surgical procedures (mean of 1.92 procedures [range, 0-9] after

    There is renewed interest in sparing the pectoralis major muscle in implant breast reconstruction, placing the implant in the subcutaneous position. This advance is made reliable by improvements in mastectomy skin flap quality, evolution of technique, and increased awareness of breast animation deformity. This retrospective review presents 13 patients (23 breasts) reconstructed immediately with placing the definitive implant in the subcutaneous space without disruption of the underlying chest muscles. None of the 13 patients had breast animation deformity postoperatively. One patient experienced an early hematoma, and 3 patients had small seromas that resolved uneventfully. One morbidly obese patient undergoing chemotherapy using a nearby chest port experienced infection requiring implant removal. This study describes an early experience, demonstrates feasibility, and discusses patient selection considerations that are important because we continue to evolve breast reconstruction approaches.

    Breast implant use has tripled in the last decade with over 320,000 breast implant based reconstructions and augmentations performed in the US per annum. Unfortunately a considerable number of women will experience capsular contracture, the irrepressible and disfiguring, tightening and hardening of the fibrous capsule that envelops the implant. Functionalising implant surfaces with biocompatible tissue-specific textures may improve in vivo performance. A novel biomimetic breast implant is presented here with anti-inflammatory in vitro abilities. Topographical assessment of native breast tissue facilitated the development of a statistical model of adipose tissue. 3D grayscale photolithography and ion etching were combined to successfully replicate a surface modelled upon the statistics of breast tissue. Pro-inflammatory genes ILβ1, TNFα, and IL6 were downregulated (p<0.001) and anti-inflammatory gene IL-10 were upregulated on the novel surface. Pro-inflammatory cytokines Gro-Alpha, TNFα and neutrophil chemoattractant IL8 were produced in lower quantities and anti-inflammatory IL-10 in higher quantities in culture with the novel surface (p<0.01). Immunocytochemistry and SEM demonstrated favourable fibroblast and macrophage responses to these novel surfaces. This study describes the first biomimetic breast tissue derived breast implant surface. Our findings attest to its potential translational ability to reduce the inflammatory phase of the implant driven foreign body reaction.

    The spacing of pregnancies has a positive impact on maternal and newborn health. The progestin contraceptive implant, which is a long-acting, reversible method of contraception, has a well-established low failure rate that is compatible with tubal sterilization. The standard provision of contraceptive methods on the first postpartum visit may put some women at risk of unintended pregnancy, either due to loss to follow-up or having sexual intercourse prior to receiving contraception. Therefore, the immediate administration of contraception prior to discharge from the hospital that has high efficacy may improve contraceptive prevalence and prevent unintended pregnancy. To compare the initiation rate, effectiveness, and side effects of immediate versus delayed postpartum insertion of implant for contraception. We searched for eligible studies up to 28 October 2016 in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and POPLINE. We examined review articles and contacted investigators. We also checked registers of ongoing clinical trials, citation lists of included studies, key textbooks, grey literature, and previous systematic reviews for potentially relevant studies. We sought randomised controlled trials (RCTs) that compared immediate postpartum versus delayed insertion of contraceptive implant for contraception. Two review authors (JS, YW) independently screened titles and abstracts of the search results, and assessed the full-text articles of potentially relevant studies for inclusion. They extracted data from the included studies, assessed risk of bias, compared results, and resolved disagreements by consulting a third review author (PL or SK). We contacted investigators for additional data, where possible. We computed the Mantel-Haenszel risk ratio (RR) with 95% confidence interval (CI) for binary outcomes and the mean difference (MD) with 95% CI for continuous variables.

    To explore the method of implant coverage with local soft tissue in immediate implant-based breast reconstruction and to evaluate the early effectiveness. Between April 2014 and August 2015, 11 patients with breast cancer underwent immediate breast reconstruction with implants after mastectomy, and the clinical data were reviewed retrospectively. The age ranged 29-48 years (mean, 36 years). The disease duration was from 7 days to 12 months (median, 3 months). According to tumor staging, 3 cases were rated as T(is)N0M0, 4 cases as T1N0M0, and 4 cases as T2N0M0. The implants were covered with local soft tissue according to the volume of mastectomy and contralateral breast size, including pectoralis major myocutaneous flaps with inframammary adipofasical flaps (3 cases), with serratus anterior fascial flap (5 cases), with rectus sheath fascial flap (1 case), and with serratus anterior fascial flap and rectus sheath fascial flap (2 cases). The size of pectoralis major myocutaneous flaps ranged from 15 cm x 9 cm to 20 cm x 15 cm, and the serratus anterior fascial flaps from 10 cm x 8 cm to 15 cm x 10 cm, and the rectus sheath fascial flap from 8 cm x 6 cm to 10 cm x 8 cm. One patient had partial nipple necrosis postoperatively and was cured, and no other postoperative complications of hematoma, infection, or implant exposure was found. The patients were followed up 4-13 months (median, 8 months). The reconstructive outcomes were excellent in 10 cases and good in 1 case, with an excellent and good rate of 100%. During follow-up, no rupture or exposure of the implant was observed; capsular contracture (Baker grade II) occurred in 1 case. Adequate coverage of implants with different local soft tissue flaps can achieve satisfactory early effectiveness in immediate implant-based breast reconstruction after mastectomy.

    Full Text Available Silicone breast implants consist of biomaterials widely used in breast reconstitution surgeries or in mammary augmentation for esthetic reasons. A preliminary stage of the implant production process is vulcanization, which consists of heating the implant to 165±5°C for approximately 9 hours. The aim of this work was to evaluate the bioburden of silicone breast implants prior to the vulcanization process and the decline in bioburden due to this process, and to confirm the sterility of the gel contained in the membrane. Breast implant production stages were evaluated by microbial counting in different steps, according to the USP 32 methodology. To evaluation of decrease in microbial load, spores strips were introduced inside the implant, and after vulcanization cycles the strips were removed from the implant. The strips were transferred to tubes containing TSB, followed by incubation for 7 days at 30-35°C. The results obtained showed that the level of microbial contamination of gel implants is relatively low, and that vulcanization allowed for the inactivation of up to 108 spores. This study led us to the conclusion that vulcanization leaded to sterility of the gel inside the product. Thus, the final sterilizing process contributed to an increase in the Sterility Assurance Level 1. Keywords: Silicone. Breast implant. Sterilization. Dry heat. Vulcanization. Bioburden.

    Objective To evaluate the success rates of immediate and delayed placement of implants with respect to the causes of tooth extraction and implant positions. Methods A total of 310 dental implants (immediate implants∶ delayed implants=76∶ 234) were inserted into 80 patients. The types, sizes and positions of the implants and the causes of tooth extraction were recorded. We then investigated the relationship of implant loss with the causes of tooth extraction and placement methods. Results A higher failure rate was found for the implants in the posterior region of the maxilla, and when periodontitis was cited as a reason for tooth extraction. The overall success rates were 93.4% and 95.7% in the immediate and delayed implant placement groups, respectively, after a 2-year follow-up. No obvious relationship of success rate was observed with the implant placement method, cause of tooth extaction, and implants' position. Conclusion The immediate placement of implants into fresh extraction sockets could offer advantages over the delayed implant placement. It seems to be a safe and predictable method for patients.

    Full Text Available Background: Traditionally, pre-operative breast markings are usually made using an indelible marker. These markings are at risk of being removed by pre-operative cleaning, positional changes and parenchymal changes post-incision. We present our approach to breast surgery with rib or intercostal markings using methylene blue. Methods: Using an indelible marker, markings are made on the breast and the inframammary crease. A blue needle (23 G mounted on a 1 ml syringe is prepared, and aliquots of 0.1 ml of methylene blue are injected. Excessive infiltration and pre-operative local anaesthetic infiltration result in diffusion of the dye and difficulty with accuracy. Dye is injected directly over the bony periosteum closest to the inframammary fold. Results: We achieved good symmetry of bilateral breast implants. Photographs were taken pre-operative and 3 months post-operative and were evaluated independently by medical officers. All results were rated as good or very good. We had 39 patients and follow-up was between 3 and 24 months. There were no implant-related complications. Conclusions: For accurate implant placement, a fixed position must be found. Our technique utilises the relative immobility of the ribs for accurate implant placement. Disadvantages to our method were few, and we had two cases of dizziness or patients feeling faint due to pain. There is also a potential allergic or anaphylaxis reaction, but we did not experience any allergic reaction.

    Breast implants and, more recently, autologous fat grafting are the two most common treatments used to correct tuberous breast deformity (TBD). The post-surgical quality of life between the two techniques is not well demonstrated. This study aimed to compare satisfaction and health-related quality of life in patients affected by TBD between these two techniques. All TBD patients operated between January 2008 and May 2015 were retrospectively identified, and only those treated with implants or lipofilling were included. Satisfaction was evaluated at least 6 months after surgery with the postoperative Breast-Q(®) augmentation module. From January 2008 to May 2015, 62 patients were recruited in our study, and 37 patients were evaluated using a Breast-Q questionnaire after at least 6 months of follow-up. Breast implant-augmented patients were significantly more satisfied concerning the "satisfaction with breasts" module (p = 0.002) and the "satisfaction with outcome" module (p = 0.00008). A question-by-question analysis revealed several interesting and significant differences, showing higher scores in most of the questions in the breast implant group. Patients in the lipofilling group, interestingly, had a mean of 1.6 interventions compared to the mean 1.36 interventions in the implant group (p = 0.23). This reflects the need to perform more surgical sessions in the lipofilling group to achieve a satisfactory result. Our study demonstrated that tuberous breast correction with implants can achieve better satisfaction along with good outcomes than lipofilling usually does.

    This paper explores the potential of implantable magnetic nanocomposites for the localized treatment of breast cancer via hyperthermia. Magnetite (Fe3O4)-reinforced polydimethylsiloxane composites were fabricated and characterized to determine their structural, magnetic, and thermal properties. The thermal properties and degree of optimization were shown to be strongly dependent on material properties of magnetic nanoparticles (MNPs). The in-vivo temperature profiles and thermal doses were investigated by the use of a 3D finite element method (FEM) model to simulate the heating of breast tissue. Heat generation was calculated using the linear response theory model. The 3D FEM model was used to investigate the effects of MNP volume fraction, nanocomposite geometry, and treatment parameters on thermal profiles. The implications of the results were then discussed for the development of implantable devices for the localized treatment of breast cancer.

    The availability of different styles of silicone gel implants-including traditional round devices and shaped, form-stable implants-offers a variety of choices for women undergoing breast augmentation and reconstruction. The purpose of this analysis was to characterize clinical outcomes associated with the Mentor MemoryGel (round) MemoryShape/Contour Profile Gel (shaped) devices through 9 years of use in women undergoing breast augmentation or reconstruction. The Mentor Core studies are nonrandomized, open-label clinical trials designed to assess the long-term safety and efficacy of silicone gel breast implants. The cumulative incidence of selected complications and reoperations was estimated using the Kaplan-Meier method. Patient satisfaction was assessed by asking the patient if she would decide to have breast implant surgery again. Shaped implants were associated with lower cumulative incidence rates of Baker Grade III/IV capsular contracture compared with round implants (3.4% vs 11.3%, respectively, in primary augmentation, P < 0.0001; 15.6% vs 24.4% in revision-augmentation, P < 0.05). Reoperation, explantation, and infection rates were comparable between devices across cohorts, except for lower incidence of infection with shaped than round implants in primary reconstruction (1.6% vs 6.2%, P < 0.05). Rupture rates were lower with shaped implants, with significance reached in primary augmentation patients at 8 years (3.1% vs 10.3%, P < 0.05). High levels of patient satisfaction (exceeding 94%) with both devices were reported at 9 years across cohorts. Prospective data through 9 years support comparable safety of round and shaped breast implants, and high levels of patient satisfaction, in patients undergoing primary and revision breast augmentation and reconstruction.

    Since the 1960s, silicone implants have been used for breast augmentations, both cosmetically and in reconstructive surgery. Tissue exposed to silicone can react with multiple adverse advents. Autoimmune/inflammatory syndrome induced by adjuvants due to silicone exposure from ruptured silicone...... implants can lead to different interstitial lung manifestations predominantly with granuloma evolvement, leading to the so-called silicone implant incompatibility syndrome (SIIS). This case describes a 57-year-old woman with multiple lung infiltrations and a left-sided breast implant. The implant had been...

    In this study, we report on the changes in psychosocial functioning over 1 year following breast cancer surgery in 3 groups of women, including those with mastectomy alone, those with mastectomy and immediate reconstruction, and those with delayed reconstruction. Women with breast cancer at 2 teaching hospitals in Ontario who were undergoing mastectomy alone, mastectomy with immediate reconstruction, or delayed reconstruction were asked to complete a battery of psychosocial questionnaires at their preoperative appointment and 1 year following surgery. A total of 190 women consented to participate in the study and completed the presurgical questionnaires. There were no presurgical differences between the 3 groups in quality of life, anxiety, depression, or sexual functioning. However, women who were undergoing delayed breast reconstruction (i.e., already had a mastectomy) had higher levels of body stigma (P = 0.01), body concerns (P = 0.002), and transparency (P = 0.002) than women who were undergoing mastectomy alone or mastectomy with immediate reconstruction. Of these women, 158 (83.2%) completed the 1-year follow-up. There were no significant differences in any of the psychosocial functioning scores between the 3 groups. Contrary to the assumed psychological benefits of breast reconstruction, psychological distress was evident among women regardless of reconstruction or timing of reconstruction. Further, psychosocial functioning (including quality of life, sexual functioning, cancer-related distress, body image, depression, and anxiety) was not different at 1-year postsurgery between women with mastectomy alone, mastectomy with immediate reconstruction, and delayed reconstruction. These results suggest that women need psychosocial support after breast cancer diagnosis, even if they have breast reconstruction.

    Breast cancer is the most common form of cancer among Swedish women. The incidence has increased since the beginning of the 1970s. Simultaneously the age-standardized mortality has been relatively constant, which is probably explained by earlier tumour detection as a result of improved diagnostic methods and treatment advances. Most patients have surgery and additional therapy such as radiation, chemotherapy and/or endocrine therapy. For those subjected to mastectomy, a brea...

    The aim of this study is to assess the accuracy of immediately placed implants using Anatomage Invivo5 computer-assisted design/computer-assisted manufacturing (CAD/CAM) surgical guides and compare the accuracy to delayed implant placement protocol. Patients who had implants placed using Anatomage Invivo5 CAD/CAM surgical guides during the period of 2012-2015 were evaluated retrospectively. Patients who received immediate implant placements and/or delayed implant placements replacing 1-2 teeth were included in this study. Pre- and postsurgical images were superimposed to evaluate deviations at the crest, apex, and angle. A total of 40 implants placed in 29 patients were included in this study. The overall mean deviations measured at the crest, apex, and angle were 0.86 mm, 1.25 mm, and 3.79°, respectively. The means for the immediate group deviations were: crest = 0.85 mm, apex = 1.10, and angle = 3.49°. The means for the delayed group deviations were: crest = 0.88 mm, apex = 1.59, and angle = 4.29°. No statistically significant difference was found at the crest and angle; however, there was a statistically significant difference between the immediate and delayed group at the apex, with the immediate group presenting more accurate placements at the apical point than the delayed group. CAD/CAM surgical guides can be reliable tools to accurately place implants immediately and/or in a delayed fashion. No statistically significant differences were found between the delayed and the immediate group at the crest and angle, however apical position was more accurate in the immediate group.

    2017-06-01

    Reconstructive surgeons are encountering an increasing number of obese women requiring postmastectomy reconstruction. These patients are poor candidates for autologous and prosthetic-based reconstructions as they have a high rate of reconstructive failure, surgical complications, and poor aesthetic outcomes. We demonstrate here the utility of the previously described Goldilocks mastectomy with free nipple grafts as a safe bridge to second stage implant-based breast reconstruction. Ten consecutive morbidly (BMI > 40) or super obese (BMI>50) women underwent bilateral Goldilocks mastectomy with free nipple grafts followed by second stage subpectoral implant placement at least three months postoperatively. Patients were assessed for implant-related complications including malposition, capsular contracture, dehiscence, and extrusion. Ten postmastectomy reconstructions in patients with BMIs ranging from 37 to 50 with a mean BMI of 45 underwent bilateral Goldilocks mastectomy with free nipple grafts. Two patients had wound healing complications after Goldilocks mastectomy but were completely healed within 8 weeks. There were no instances of delayed wound healing or reconstructive failure after prosthetic placement. With at least 9 months of follow-up on all patients, no patient has had a capsular contracture, significant malposition, or other complication requiring reoperation. The obese patient poses a significant reconstructive challenge for which no reproducible approach has been described. Here, we present a 2-stage strategy: the previously described Goldilocks mastectomy with free nipple grafts followed by second stage subpectoral definitive implant placement. This is the first proposed description of a reliable strategy for postmastectomy reconstruction in the morbidly and super obese.

    Full Text Available Breast augmentation with implantation represents a challenge for subsequent radiographic imaging and pathological sampling. Fine-needle aspiration biopsy (FNAB is an excellent technique to sample suspicious lesions that are adjacent to fragile implants. We report a case of a 51-year-old woman with breast implants presenting with an initial diagnosis of fibroadenoma by imaging studies. A definite diagnosis of mammary carcinoma with plasmacytoid cells was made on ultrasound (US-guided FNAB of the breast mass with rapid on-site evaluation which initiated core needle biopsy of the mass and subsequent mastectomy with sentinel lymph node biopsy. Our case exemplifies the role of US-guided FNAB for the initial investigation of breast masses in patients with implants. In addition, the case illustrates the cytomorphological features of the tumor cells in primary neuroendocrine carcinoma of the breast.

    Delay in seeking treatment for breast cancer is a barrier to the early diagnosis and management of the disease, resulting in a poorer prognosis. We here estimated the prevalence of delayed presentation for breast cancer and identified possible influential sociodemographic factors in a cross-sectional study of 250 patients diagnosed with primary breast cancer at the Radiotherapy and Oncology Clinic in Kuala Lumpur Hospital. Data were collected by face-to-face interview using a structured questionnaire and from medical records. We examined associations between delayed presentation (presenting to a physician more than 3 months after self-discovery of a symptom) and sociodemographic characteristics, practice of breast self examination (BSE), history of benign breast disease, family history of breast cancer and type of symptom, symptom disclosure and advice from others to seek treatment using multiple logistic regression. Time from self-discovery of symptom to presentation ranged from tghe same day to 5 years. Prevalence of delayed presentation was 33.1% (95%CI: 27.4, 39.3). A significantly higher proportion of delayers presented with late stages (stage III/IV) (58.3% vs. 26.9%, p<0.001). Divorced or widowed women (OR: 2.23, 95% CI: 1.11, 4.47) had a higher risk of delayed presentation than married women and women who never performed breast self examination were more likely to delay presentation compared to those who regularly performed BSE (OR: 2.74, 95% CI: 1.33, 5.64). Our findings indicate that delayed presentation for breast cancer symptoms among Malaysian women is high and that marital status and breast self examination play major roles in treatment-seeking for breast cancer symptoms.

    Use of long-acting, highly effective contraception has the potential to improve women's ability to avoid short interpregnancy intervals, which are associated with an increased risk of maternal morbidity and mortality, and preterm delivery. In Uganda, contraceptive implants are not routinely available during the immediate postpartum period. The purpose of this study was to compare the proportion of women using levonorgestrel contraceptive implants at 6 months after delivery in women randomized to immediate or delayed insertion. This was a randomized controlled trial among women in Kampala, Uganda. Women who desired contraceptive implants were randomly assigned to insertion of a 2-rod contraceptive implant system containing 75 mg of levonorgestrel immediately following delivery (within 5 days of delivery and before discharge from the hospital) or delayed insertion (6 weeks postpartum). The primary outcome was implant utilization at 6 months postpartum. From June to October 2015, 205 women were randomized, 103 to the immediate group and 102 to the delayed group. Ninety-three percent completed the 6 month follow-up visit. At 6 months, implant use was higher in the immediate group compared with the delayed group (97% vs 68%; P < .001), as was the use of any highly effective contraceptive (98% vs 81%; P = .001). Women in the immediate group were more satisfied with the timing of implant placement. If given the choice, 81% of women in the immediate group and 63% of women in the delayed group would choose the same timing of placement again (P = .01). There were no serious adverse events in either group. Offering women the option of initiating contraceptive implants in the immediate postpartum period has the potential to increase contraceptive utilization, decrease unwanted pregnancies, prevent short interpregnancy intervals, and help women achieve their reproductive goals.

    Optimisation of the cosmetic outcome after breast-conserving therapy (BCT) is important. We aimed to determine the cosmetic outcome following BCT and factors influencing this cosmesis and identify the most favourable options for delayed breast reconstruction. Four reconstructive surgeons evaluated the cosmetic outcome of 109 patients after BCT. Additionally, the surgeons indicated which patients were amenable for delayed reconstruction and the preferred type of reconstruction. The inter- and intra-observer agreement of the surgeons was rated. The mean overall cosmetic outcome was rated as fair (2.7/4.0, SD 0.9, 1.0-4.0). Risk factors for a poor cosmesis were larger breast size (OR 3.81, p = 0.040), larger tumour (OR 1.63, p = 0.028) and axillary lymph node dissection (ALND) (OR 3.09, p = 0.013). Reconstruction of the ipsilateral side was recommended in 55.6% and 94.5% and contralateral reconstruction in 16.7% and 73.3% of patients with good and poor cosmesis, respectively. Flap reconstruction and lipofilling were most commonly reported for the ipsilateral, and breast reduction for the contralateral breast, with reasonable improvement expected (2.2/4.0, SD 0.5, 1.08-3.3). The inter- (0.5-0.7) and intra-observer (0.63-0.79) agreement of the cosmesis was moderate to good, however, poor regarding the recommended reconstruction techniques (mainly breast and tumour size and ALND. Although several reconstructive options are available, the optimal method for revision surgery has not yet been determined.

    Loading implants immediately after their position in alveolar bone crest is a procedure that has become popular in the last decade. The aim of this study is to evaluate the survival rate of 811 immediate loaded implants (ILIs). In the period between January 2008 and December 2013, 877 patients (498 females and 379 males) were operated at the BDD private Practice Clinic (Milan, Italy). The mean post-surgical follow-up was 30±17 months (max – min, 84 – 1). One thousasnd three hundred and eighty-six fixtures (EDIERRE Implant System SpA, Genoa, Italy) were evaluated in the present study, 811 immediately loaded and 575 loaded after 3 months. All patients underwent the same surgical protocol and agreed to participate in a post-operative check-up program. SPSS program was used for statistical analysis. Survival rate (SVR) was 97.3% since only 38 fixtures were lost from a total of 1,348 implants. Cross-tabulation between failures demonstrated slight but significant worse results for ILIs (p= 0.037). There were 28 failures out of 811 ILIs whereas only 10 fixtures were lost out of 565 implants loaded after 3 months. Immediate loading performed in selected cases is a reliable tool for oral rehabilitation.

    The current approach to breast reconstruction remains largely subjective and is based on physical examination and visual-estimates of breast size. Thus, the overall success of breast reconstruction is limited by the inability of plastic surgeons to objectively assess breast volume and shape, which may result in suboptimal outcomes. A potential solution to this obstacle may be three-dimensional (3D) imaging, which can provide unique clinical data that was previously unattainable to plastic surgeons. The following study represents a prospective analysis of patient volunteers undergoing unilateral tissue expander (TE)-implant reconstruction by one of the two senior authors (MC, NSK). All patients underwent unilateral mastectomy with immediate or delayed insertion of a TE, followed by an exchange for a permanent silicone or saline implant. 3D scans were obtained during routine pre- and postoperative office visits. The 3D breast-volume calculations served as a guide for surgical management. Twelve patients have completed 3D-assisted unilateral breast reconstruction to date. These patients represent a wide range of body habitus and breast size/shape; 3D volume range from 136 to 518 cm(3). The mean baseline breast asymmetry in this group was 12.0 +/- 10.8%. Contralateral symmetry procedures were performed in eleven patients, consisting of the following: mastopexy (n = 6), augmentation (n = 1), mastopexy/augmentation (n = 2), and reduction mammoplasty (n = 2). Reconstruction was completed in a total number of 2 (n = 10) or 3 (n = 2) operations. Overall breast symmetry improved at the completion of reconstruction in the majority of patients, with an average postoperative symmetry of 95.1 +/- 4.4% (relative to 88% preoperatively). 3D imaging serves a valuable adjunct to TE-implant breast reconstruction. This technology provides volumetric data that can help guide breast reconstruction, such as in choosing the initial TE size, total volume of expansion, and final implant size

    We describe a novel technique for the sampling of breast implant-associated seroma. Using a blunt-tip lipofilling cannula, we have the freedom of movement to sample all fluid collections and prevent the misfortunes of damaging the implant. Also, we have demonstrated the inability of the Coleman style I lipofilling cannula to perforate a silicone breast implant. This practical and reliable technique will prove to be useful in managing the breast implant-associated seroma, especially with the rising incidence of the anaplastic large cell lymphoma, where the sampling of seroma is mandatory.

    Full Text Available Aims and Objectives : To assess the efficacy of flapless implant surgery on soft-tissue profile and to compare the clinical outcomes of flapless implant therapy on immediate loading (IL implants to delayed loading (DL implants. Materials and Methods : The study sample consisted of 20 patients who were partially edentulous in the anterior maxillary region. They were divided into two groups. In group I (IL 10 implants were placed and immediately provisionalized and restored with a metal ceramic crown on the 14th day. In group II (DL 10 implants were placed and loaded after 4 months. Single-piece implants were used for the IL group and two-piece implants were used for the DL group. All soft tissue parameters i.e., modified plaque index (mPI, modified bleeding index (mBI, papillary index (PPI, marginal level of soft tissue (ML and width of keratinized mucosa (WKM were recorded at baseline, Day 60, Day 120 and Day 180. Results: The success rate in group I was found to be 80%, which was lower than the success rate in group II which was found to be 90%. On comparison, there is no statistically significant difference in success rate between the two study groups. There was no statistically significant difference between the groups over time in parameters like mPI, mBI, ML and WKM. The mean PPI score in group II showed a significant increase from when compared to group I. Conclusion: The results of this study indicated that flapless implant surgery using either immediately loading implants or DL implants, demonstrate enhancement of implant esthetics.

    Although neurophysiological and psychophysical proof of osseoperception is accumulating, histomorphometric evidence for the neural mechanisms of functional compensation following immediate and delayed implant loading is still lacking. For this randomized split-mouth study, six mongrel dogs randomly received one of four treatment protocols at 36 implant-recipient sites over 16 weeks (third maxillary incisor, third and fourth mandibular premolar):immediate implant placement and immediate loading (IIP1IL);delayed implant placement and delayed loading (DIP1DL);delayed implant placement and immediate loading (DIP1IL);and natural extraction socket healing (control). Histomorphometry was performed in the peri-implant bone and soft tissues within 300 mm around the implants. Immunocytochemistry and transmission electron microscopy were used to confirm the presence of neural structures and to reveal their ultrastructural characteristics, respectively. Myelinated nerve fibres densely populated the peri-implant crestal gingival and apical regions, although they were also identified in the woven bone and in the osteons near the implant threads. Compared with the control group in the mandible, the group that received IIP1IL showed a higher innervation (in N?mm22, 5.9461.12 vs. 3.1560.63, P,0.001) and smaller fibre diameter (in mm, 1.3760.05 vs. 1.6460.13, P50.016), smaller axon diameter (in mm, 0.8960.05 vs. 1.2460.10, P50.009) and g-ratio (0.6460.04 vs. 0.7660.05, P,0.001) in the middle region around the implants. Compared with DIP1IL in the mandible, IIP1IL had a higher nerve density (in N?mm22, 13.2362.54 vs. 9.6461.86, P50.027), greater fibre diameter (in mm, 1.3260.02 vs. 1.2060.04, P50.021), greater axon diameter (in mm, 0.9260.01 vs. 0.8960.03, P50.035) and lower g-ratio (0.6960.01 vs. 0.7460.01, P50.033) in the apical region around the implants. It may be assumed that the treatment protocol with IIP1IL is the preferred method to allow optimized peri-implant re

    Breast cancer is the most common cancer, and one of the leading causes of death for females in Jordan and many countries in the world. Studies have shown that delay in symptoms presentation, diagnosis or treatment would result in poor prognosis. There has been no published study from Jordan on delays in patient presentation, delays in diagnosis, or delays in treatment. Therefore, we conducted this study to assess these important quality indicators aiming to improve prognosis for breast cancer patients in Jordan. This project was a cross-sectional study on female breast cancer patients in Jordan. The total number of participants was 327. The proportion of patients with presentation delay, diagnosis delay, and treatment delay was 32.2%, 49.1%, or 32.4%, respectively. The main reported reasons for delay in presentation were ignorance of the nature of the problem (65.6%), limited/lack of knowledge that symptoms were suggestive of cancer diagnosis (16.7%), and misdiagnosis (16.7%). Predictors of delay and mean time for presentation, diagnosis, and treatment were identified. Our results reveal that breast cancer patients in Jordan are experiencing delays in presentation, diagnosis, and treatment. This could justify the advanced stages at diagnosis and poor outcomes for breast cancer patients in Jordan. We recommend revising the current early detection and down-staging programs in Jordan.

    Several companies offer anatomically shaped breast implants but differences among manufacturers are often misunderstood. The shell texture is a crucial parameter for anatomically shaped implants to prevent rotation and to decrease the risk of capsular contracture, even though concerns have recently been raised concerning the complications associated with textured breast implants. The aim of this study was to characterize differences in terms of texture, cell adhesion, shape, and stiffness between some commonly used anatomically shaped implants from three different manufacturers. Five commercially available anatomically shaped breast implants from 3 different manufacturers (Allergan, Mentor, and Sebbin) were used. Scanning electron microscopy, X-ray microtomography, and scanning mechanical microscopy were used to characterize the shell texture. Human fibroblast adhesion onto the shells was evaluated. 3D models of the implants were obtained using CT-scan acquisitions to analyze their shape. Implant stiffness was evaluated using a tractiometer. Major differences were observed in the topography of the textures of the shells, but this was not conveyed by a statistically significant fibroblast adhesion difference. However, fibroblasts adhered better on anatomically shaped textured implants than on smooth implants (p Book Reviews, and manuscripts that concern Basic Science, Animal Studies, Cadaver Studies, and Experimental Studies.

    Even if the safety of the polyurethane prosthesis has been the subject of many studies and professional and public controversies. Nowadays, polyurethane covered implants are very popular in plastic surgery for the treatment of capsular contracture. We have identified 41 papers (1 is a communication of the FDA) by using search browsers such as Pubmed, Medline, and eMedicine. Eleven manuscripts have been used for an introduction, and the remaining thirty have been subdivided into three tables whose results have been summarized in three main chapters: (1) capsular formation and contracture, (2) complications, (3) biodegradation and cancer risk. (1) The polyurethanic capsule is a well defined foreign body reaction characterized by synovial metaplasia, a thin layer of disarranged collagen fibers and a high vascularization. These features make possible a "young" capsule and a low occurrence of capsular contracture even over a long period (10 years); (2) the polyurethane implants may be difficult to remove but there is no evidence that they cause an increase in the other complications; (3) there is no evidence of polyurethane related cancer in long-term studies (after 5 years). Polyurethane foam covered breast implants remain a valid choice for the treatment of capsular contracture even if it would be very useful to verify the ease of removal of the prosthesis and to continue investigations on biodegradation products.

    Full Text Available Objective: To determine speech-perception-in-noise (with speech and noise spatially distinct and coincident and bilateral spatial benefits of head-shadow effect, summation, squelch and spatial release of masking in adults with delayed sequential cochlear implants. Study design: A cross-sectional one group post-test-only exploratory design was employed. Eleven adults (mean age 47 years; range 21 – 69 years of the Pretoria Cochlear Implant Programme (PCIP in South Africa with a bilateral severe-to-profound sensorineural hearing loss were recruited. Prerecorded Everyday Speech Sentences of The Central Institute for the Deaf (CID were used to evaluate participants’ speech-in-noise perception at sentence level. An adaptive procedure was used to determine the signal-to-noise ratio (SNR, in dB at which the participant’s speech reception threshold (SRT was achieved. Specific calculations were used to estimate bilateral spatial benefit effects. Results: A minimal bilateral benefit for speech-in-noise perception was observed with noise directed to the first implant (CI 1 (1.69 dB and in the speech and noise spatial listening condition (0.78 dB, but was not statistically significant. The head-shadow effect at 180° was the most robust bilateral spatial benefit. An improvement in speech perception in spatially distinct speech and noise indicates the contribution of the second implant (CI 2 is greater than that of the first implant (CI 1 for bilateral spatial benefit. Conclusion: Bilateral benefit for delayed sequentially implanted adults is less than previously reported for simultaneous and sequentially implanted adults. Delayed sequential implantation benefit seems to relate to the availability of the ear with the most favourable SNR.

    First-generation polyurethane foam-coated breast implants were associated with a low risk of capsular contracture (CC), but the risk of CC with modern polyurethane-coated silicone implants has not been established. The authors sought to determine the long-term rates of CC after primary breast augmentation with Microthane, a polyurethane-coated silicone gel implant. A total of 131 patients (255 breasts) were evaluated in a retrospective study. Data were compiled from postoperative follow-up sessions at 2 weeks; 1, 3, 6, and 12 months; and annually thereafter. Rates of various complications, including CC, were determined. CC developed in 3 of the 255 implanted breasts (1.2%; Baker grade III or IV), and postoperative hematoma occurred in 2 implanted breasts (0.8%). Spontaneous CC that was not associated with other complications was observed in 1 implanted breast (0.4%). All instances of CC occurred before the 31st postoperative month. For patients who undergo primary breast augmentation with modern polyurethane-coated implants, the long-term risk of CC is low. 3 Therapeutic. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

    Background: The demand for reconstructive breast procedures of various types has accelerated in recent years. Coupled with increased patient expectations, it has fostered the development of oncoplastic and reconstructive techniques in breast surgery. In the setting of postmastectomy reconstruction, patient satisfaction and quality of life are the most significant outcome variables when evaluating surgical success. The aim of this study was to evaluate the quality of life after implant breast reconstruction compared with autologous breast reconstruction. Materials and Methods: A cross-sectional study design was used. A total of 65 women who had completed postmastectomy implant-based or autologous reconstruction in the participating center were asked to complete the BREAST-Q (Reconstruction Module). Results: Data analysis demonstrated that women with autologous breast reconstruction were significantly more satisfied with their breasts (P = 0.0003) and with the overall outcome (P = 0.0001) compared with women with implant breast reconstruction. All other BREAST-Q parameters that were considered and observed were not significantly different between the 2 patient groups. Conclusions: Through statistical analysis, our results showed that patients who underwent autologous tissue reconstruction had better satisfaction with the reconstructed breast and the outcome, while both techniques appear to equally improve psychosocial well-being, sexual well-being, and chest satisfaction.

    Background Increasing numbers of patients with breast cancer are being treated with postmastectomy radiation therapy (PMRT). The author reviewed the literature to determine the clinical impact of this increasing use of PMRT in patients with breast cancer who desire implant-based breast reconstruction. Methods The author searched the MEDLINE database for articles on breast reconstruction and radiation therapy published between January 2008 and June 2011, and reviewed the abstracts of those articles to identify articles with information about the impact of radiation on implant-based breast reconstruction. This subgroup of articles was reviewed in detail. Results Two-hundred eighty-five articles were identified. 19 papers were reviewed in detail. 8 papers provided level III evidence; one provided level I or II (n = 8) evidence from high-quality multicenter or single-center randomized controlled trials or prospective cohort studies. Two papers provided level IV evidence from case series and were included in the review because they offered a novel approach or perspective. The most recent studies find a significant need for unplanned or major corrective surgery in irradiated breasts reconstructed with implants. Although breast implant reconstruction in irradiated breasts is associated with high rates of complications; only a minority of patients require conversion to an autologous tissue flap. Conclusions Although the majority of patients who undergo implant-based reconstruction and receive radiation ultimately keep the implant reconstruction, patient surveys show that radiation has a significantly negative effect on patient satisfaction.

    We describe in this paper our experience with the technique of skin-reducing mastectomy in the treatment of breast cancer. Between October 2005 and April 2010 in our Center 33 patients underwent breast surgery utilizing the skin-reducing mastectomy technique and immediate breast reconstruction with expansor/definitive implant Becker 35 contour profile. Contralateral symmetrization was performed in the same operation. All selected patients satisfied inclusion critera either for nipple-sparing mastectomy or prophylactic mastectomy. We selected patients who had large ptosic breasts: areola-submammary fold >8 cm and jugular-nipple distance >25 cm. After histologic exam to confirm the lack of retroareolar tissue infiltration the nipple was preserved in a superior flap. Twenty-four out of 33 patients (72.7%) did not suffer from complications. In 9 patients (27.3%) we observed early complications. During follow-up we observed in 24 patients (72.7%) Baker I capsular contracture, in 9 patients (27.3%) Baker II capsular contracture. Esthetic results of symmetry, shape and volume were good to optimal. Patients' satisfaction was similar. During the follow up (6-33 months, average 17.7 months) no patient suffered from breast cancer recurrence. The "skin-reducing mastectomy" reduces mutilation and unsightly scar visibility. It gives a pleasant aesthetic outcome without hindering oncological safety.

  14. Delay in Breast Cancer: Implications for Stage at Diagnosis and Survival

    Full Text Available Breast cancer continues to be a disease with tremendous public health significance. Primary prevention of breast cancer is still not available, so efforts to promote early detection continue to be the major focus in fighting breast cancer. Since early detection is associated with decreased mortality, one would think that it is important to minimize delays in detection and diagnosis. There are two major types of delay. Patient delay is delay in seeking medical attention after self-discovering a potential breast cancer symptom. System delay is delay within the health care system in getting appointments, scheduling diagnostic tests, receiving a definitive diagnosis, and initiating therapy. Earlier studies of the consequences of delay on prognosis tended to show that increased delay is associated with more advanced stage cancers at diagnosis, thus resulting in poorer chances for survival. More recent studies have had mixed results, with some studies showing increased survival with longer delays. One hypothesis is that diagnostic difficulties could perhaps account for this survival paradox. A rapidly growing lump may suggest cancer to both doctors and patients, while a slow growing lump or other symptom could be less obvious to them. If this is the case, then the shorter delays would be seen with the more aggressive tumors for which the prognosis is worse leading to reduced survival. It seems logical that a tumor that is more advanced at diagnosis would lead to shorter survival; but the several counter-intuitive studies in this review show that it is dangerous to make assumptions.

    Full Text Available One important modality of breast cancer therapy is surgical treatment, which has become increasingly less mutilating over the last century. Breast reconstruction has become an integrated part of breast cancer treatment due to long-term psychosexual health factors and its importance for breast cancer survivors. Both autogenous tissue-based and implant-based reconstruction provides satisfactory reconstructive options due to better surgeon awareness of “the ideal breast size”, although each has its own advantages and disadvantages. An overview of the current options in breast reconstruction is presented in this article.

    Capsular contracture is a common sequelae of implant-based breast augmentation. Despite its prevalence, the etiology of capsular contracture remains controversial. Numerous studies have identified microbial biofilms on various implantable materials, including breast implants. Furthermore, biofilms have been implicated in subclinical infections associated with other surgical implants. In this review, we discuss microbial biofilms as a potential etiology of capsular contracture. The review also outlines the key diagnostic modalities available to identify the possible infectious agents found in biofilm, as well as available preventative and treatment measures. PMID:26843099

    Ever since its introduction in 1977, a minimum of few months of period is required for osseointegration to take place after dental implant surgery. With the passage of time and advancements in the fields of dental implant, this healing period is getting smaller and smaller. Immediate loading of dental implants is becoming a very popular procedure in the recent time. Hence, we retrospectively analyzed the various risk factors for the failure of delayed and immediate loaded dental implants. In the present study, retrospective analysis of all the patients was done who underwent dental implant surgeries either by immediate loading procedure or by delayed loading procedures. All the patients were divided broadly into two groups with one group containing patients in which delayed loaded dental implants were placed while other consisted of patients in whom immediate loaded dental implants were placed. All the patients in whom follow-up records were missing and who had past medical history of any systemic diseases were excluded from the present study. Evaluation of associated possible risk factors was done by classifying the predictable factors as primary and secondary factors. All the results were analyzed by Statistical Package for the Social Sciences (SPSS) software. Kaplan-Meier survival analyses and chi-square test were used for assessment of level of significance. In delayed and immediate group of dental implants, mean age of the patients was 54.2 and 54.8 years respectively. Statistically significant results were obtained while comparing the clinical parameters of the dental implants in both the groups while demographic parameters showed nonsignificant correlation. Significant higher risk of dental implant failure is associated with immediate loaded dental implants. Tobacco smoking, shorter implant size, and other risk factors play a significant role in predicting the success and failure of dental implants. Delayed loaded dental implant placement should be preferred

    Objective The benefits of cochlear implantation for children with developmental delays (DD) are often unclear. We compared cognition, adaptive behavior, familial stress, and communication in children with and without DD. Study Design Retrospective review Setting Two tertiary care pediatric hospitals Patients 204 children who underwent cochlear implantation assessed before and >1 year after implantation Main Outcome Measures The Mullen Scales of Early Learning (MSEL), Vineland Adaptive Behavior Scales (VABS), Parental Stress Index (PSI), and Preschool Language Scale (PLS). Results We developed a specific definition of DD for hearing-impaired children based upon DSM-IV criteria for mental retardation; 60 children met the criteria for DD and 144 children did not. Prior to implantation, multiple linear regression demonstrated that children with DD had lower scores in every domain of the MSEL and VABS (p0.1) compared to children without DD. After implantation, children without DD demonstrated significant improvements in intelligence as measured by the MSEL, age-appropriate improvements in adaptive behavior as evaluated by the VABS, and their familial stress levels were not increased after cochlear implantation. In contrast, children with DD underwent implantation at a later age and demonstrated less comprehensive developmental improvements after cochlear implantation and higher stress levels. However, when the age differences were taken into account using multiple linear regression analyses, the differences between two cohorts were reduced. Conclusions These data indicate that our definition of DD is a reliable method of stratifying deaf children. While children with DD have a normal developmental rate of adaptive behavior after cochlear implantation, their developmental rate of intelligence is lower and they have higher stress levels than children without DD. However, our data suggest that if children with DD could be implanted as early as children without DD, their

    One-stage implant-based breast reconstruction using titanium-coated polypropylene mesh is a novel approach widely used in Europe. Complication rates in breast reconstruction with the use of titanium-coated meshes seem to be comparable to those in patients with implant-based breast reconstruction alone. However, the use of synthetic meshes in implant-based breast reconstructive surgery leads to new clinical scenarios with the need for the breast surgeon to face new complications. We present an innovative treatment of implant exposure in the absence of infection in patients who underwent nipple-sparing mastectomy and immediate breast reconstruction with silicone implants and titanium-coated polypropylene mesh by using a pedicled sub-mammary intercostal perforator flap. Four patients who experienced implant exposure without infection have been treated with the use of a sub-mammary intercostal perforator flap. Whole coverage of the exposed implant/mesh with a sub-mammary intercostal perforator flap was obtained in all cases. No post-operative complications have been observed, whereas a pleasant aesthetic result has been achieved. Patients' post-operative quality of life and satisfaction levels were measured by the European Organisation for Research and Treatment of Cancer breast cancer-specific quality of life QLQ-BR23 questionnaire and showed an average good satisfaction with the post-operative outcomes (mean QLQ-BR23 score 1.9). For the first time, a sub-mammary intercostal perforator flap has been used with the aim of treating implant exposures without removing the prosthesis even in the presence of synthetic meshes, when wound infection was excluded. Although tested on a small series, the sub-mammary intercostal perforator flap might represent a simple, versatile and cost-effective procedure for the management of implant exposure following nipple-sparing mastectomy and immediate reconstruction with silicone implants and synthetic meshes. It should be considered to

    With the 2006 Food and Drug Administration approval of round silicone gel breast implants in the United States, there still remained a lack of versatility in implant options. The approval of Sientra's shaped cohesive implants in 2012 brought with it the innovations needed to address varying patient needs. Because access to shaped devices is still fairly recent in the United States, some surgeons remain uncomfortable with implementing shaped cohesive gel implants into their practice. The author outlines surgical techniques and algorithms from experience with the Sientra shaped device, covering the preoperative stage, measurements (base diameter, sternal notch to nipple, tissue pinch, and nipple to inframammary fold), ideal first candidates, operative techniques, and complication avoidance, as well as important factors for shaped-implant selection, including chest base diameter, implant height, implant volume, and implant projection for the patient's desired outcome. With experience, surgeons will find new utility with shaped implants for a variety of patients in their practices.

    Full Text Available Aim: The study was undertaken to find out the estrus induction and fertility response in delayed pubertal Kankrej heifers treated with norgestomet ear implant. Materials and methods: Total eighteen anoestrus Kankrej heifers of delayed puberty weighed above 250 kg and attained between 30 to 36 months of age were selected and divided in to three groups of six animals each at random to conduct the experiment. Animals in group 1 were implanted Crestar ear implant for 9 days. In addition to this, group 2 received 500 IU of PMSG on the day of implant removal. In group 3, treatment protocol remained same as in group 2, but Inj. Receptal @ 2 ml was given additionally at the time of breeding. Results: All the animals exhibited estrus with average duration of 25.41+ 0.94, 21.95+ 0.20 and 22.68 + 1.46 hours between implant withdrawal and estrus induction in group 1, 2 and 3, respectively. The duration of estrus was significantly (P<0.05 longer (25.61+ 2.95 hours in group 2, followed by group 1 (18.88 + 1.45 hours and group 3 (13.48 + 1.92 hours. The pregnancy rate at induced estrus was 33.33 percent in group 2. In group 1 and group 3 none of the heifers found pregnant at induced estrus. The overall conception rate was maximum in group 2 (66.67 percent followed by group 3 (50 percent and group 1 (33.33 percent after the 3rd service. Conclusion: Although the conception rate at induced estrus was lower, norgestomet ear implant could be utilized to induced estrus in delayed pubertal cow heifers. [Vet. World 2012; 5(8.000: 453-458

    2010-06-01

    We present the design and implementation of linear-phase delay filters for ultra-low-power signal processing in neural recording implants. We use these filters as low-distortion delay elements along with an automatic biopotential detector to perform integral waveform extraction and efficient power management. The presented delay elements are realized employing continuous-time OTA-C filters featuring 9th-order equiripple transfer functions with constant group delay. Such analog delay enables processing neural waveforms with reduced overhead compared to a digital delay since it does not requires sampling and digitization. It uses an allpass transfer function for achieving wider constant-delay bandwidth than all-pole does. Two filters realizations are compared for implementing the delay element: the Cascaded structure and the Inverse follow-the-leader feedback filter. Their respective strengths and drawbacks are assessed by modeling parasitics and non-idealities of OTAs, and by transistor-level simulations. A budget of 200 nA is used in both filters. Experimental measurements with the chosen filter topology are presented and discussed.

    Full Text Available Adrian SH Ooi,1,2 David H Song1 1Section of Plastic and Reconstructive Surgery, University of Chicago Medicine and Biological Sciences, Chicago, IL, USA; 2Department of Plastic, Reconstructive, and Aesthetic Surgery, Singapore General Hospital, Singapore Abstract: Implant-based procedures are the most commonly performed method for ­postmastectomy breast reconstruction. While donor-site morbidity is low, these procedures are associated with a higher risk of reconstructive loss. Many of these are related to infection of the implant, which can lead to prolonged antibiotic treatment, undesired additional surgical procedures, and unsatisfactory results. This review combines a summary of the recent literature regarding implant-related breast-reconstruction infections and combines this with a practical approach to the patient and surgery aimed at reducing this risk. Prevention of infection begins with appropriate reconstructive choice based on an assessment and optimization of risk factors. These include patient and disease characteristics, such as smoking, obesity, large breast size, and immediate reconstructive procedures, as well as adjuvant therapy, such as radiotherapy and chemotherapy. For implant-based breast reconstruction, preoperative planning and organization is key to reducing infection. A logical and consistent intraoperative and postoperative surgical protocol, including appropriate antibiotic choice, mastectomy-pocket creation, implant handling, and considered acellular dermal matrix use contribute toward the reduction of breast-implant infections.

    Full Text Available Background: Embarrassment and shame of visiting a doctor for a breast disease are among psychosocial factors that potentially contribute to delay in seeking medical advice. The purpose of this study is to review the published literature to determine if embarrassment regarding breast examination, diagnosis and treatment is associated with patient delay.Methods: We searched PubMed with the following key terms: patient acceptance of health care (MeSH, breast neoplasms/psychology (MeSH, shame (MeSH, embarrassment, delayed diagnosis, to find relevant literature published before August 2015.Results: The studies that explicitly assessed the association between embarrassment and delay for seeking medical advice for breast cancer were very limited. Among these studies, only 2 were quantitative studies, 4 were based on qualitative research and 4 were reviews. Other studies assessed attitudes in population-based surveys or included patients (females and males suffering from different types of cancer.Conclusions: Women should be educated that diseases of the breast need to be cared for as health issues in other parts of the body. They should be informed that embarrassment in this regard is not related to grace and integrity but can be potentially life-threatening. Further research is necessary to quantify the association of embarrassment or shame with delay in seeking diagnosis and treatment of breast cancer. More research can elucidate the ways that the negative impact of shame/embarrassment can be minimized in different ethnic groups.

    The purpose of the present meta-analysis was to test the null hypothesis of no difference in the implant failure rate, postoperative infection, and marginal bone loss for patients being rehabilitated with immediately loaded non-submerged dental implants or delayed loaded submerged implants, against the alternative hypothesis of a difference. An electronic search without time or language restrictions was undertaken in March 2014. Eligibility criteria included clinical human studies, either randomized or not. The search strategy resulted in 28 publications. The inverse variance method was used for a random- or fixed-effects model, depending on the heterogeneity. The estimates of an intervention were expressed as the risk ratio (RR) and mean difference (MD) in millimetres. Twenty-three studies were judged to be at high risk of bias, one at moderate risk of bias, and four studies were considered at low risk of bias. The difference between procedures (submerged vs. non-submerged implants) significantly affected the implant failure rate (P = 0.02), with a RR of 1.78 (95% confidence interval (CI) 1.12-2.83). There was no apparent significant effect of non-submerged dental implants on the occurrence of postoperative infection (P = 0.29; RR 2.13, CI 0.52-8.65) or on marginal bone loss (P = 0.77; MD -0.03, 95% CI -0.23 to 0.17).

    Full Text Available Abstract Background Primary non-Hodgkin lymphoma (NHL of the breast represents 0.04–0.5% of malignant lesions of the breast and accounts for 1.7–2.2% of extra-nodal NHL. Most primary cases are of B-cell phenotype and only rare cases are of T-cell phenotype. Anaplastic large cell lymphoma (ALCL is a rare T-cell lymphoma typically seen in children and young adults with the breast being one of the least common locations. There are a total of eleven cases of primary ALCL of the breast described in the literature. Eight of these cases occurred in proximity to breast implants, four in relation to silicone breast implant and three in relation to saline filled breast implant with three out of the eight implant related cases having previous history of breast cancer treated surgically. Adjuvant postoperative chemotherapy is given in only one case. Secondary hematological malignancies after breast cancer chemotherapy have been reported in literature. However in contrast to acute myeloid leukemia (AML, the association between lymphoma and administration of chemotherapy has never been clearly demonstrated. Case Presentation In this report we present a case of primary ALCL of the breast arising in reconstruction mamoplasty capsule of saline filled breast implant after radical mastectomy for infiltrating ductal carcinoma followed by postoperative chemotherapy twelve years ago. Conclusion Primary ALK negative ALCL arising at the site of saline filled breast implant is rare. It is still unclear whether chemotherapy and breast implantation increases risk of secondary hematological malignancies significantly. However, it is important to be aware of these complications and need for careful pathologic examination of tissue removed for implant related complications to make the correct diagnosis for further patient management and treatment. It is important to be aware of this entity at this site as it can be easily misdiagnosed on histologic grounds and to exclude

    Under estrogen deficiency, blastocysts cannot initiate implantation and enter dormancy. Dormant blastocysts live longer in utero than normal blastocysts, and autophagy has been suggested as a mechanism underlying the sustained survival of dormant blastocysts during delayed implantation. Autophagy is a cellular degradation pathway and a central component of the integrated stress response. Reactive oxygen species (ROS) are produced within cells during normal metabolism, but their levels increase dramatically under stressful conditions. We investigated whether heightened autophagy in dormant blastocysts is associated with the increased oxidative stress under the unfavorable condition of delayed implantation. To visualize ROS production, day 8 (short-term dormancy) and day 20 (long-term dormancy) dormant blastocysts were loaded with 1-µM 5-(and-6)-chloromethyl-2', 7'-dichlorodihydrofluorescein diacetate, acetyl ester (CM-H2DCFDA). To block autophagic activation, 3-methyladenine (3-MA) and wortmannin were used in vivo and in vitro, respectively. We observed that ROS production was not significantly affected by the status of dormancy; in other words, both dormant and activated blastocysts showed high levels of ROS. However, ROS production was higher in the dormant blastocysts of the long-term dormancy group than in those of the short-term group. The addition of wortmannin to dormant blastocysts in vitro and 3-MA injection in vivo significantly increased ROS production in the short-term dormant blastocysts. In the long-term dormant blastocysts, ROS levels were not significantly affected by the treatment of the autophagy inhibitor. During delayed implantation, heightened autophagy in dormant blastocysts may be operative as a potential mechanism to reduce oxidative stress. Further, ROS may be one of the potential causes of compromised developmental competence of long-term dormant blastocysts after implantation.

    Increasing numbers of women undergo breast implantation for cosmetic and reconstructive purposes. Contracture of the fibrous capsule, which encases the implant leads to significant pain and reoperation. Texture, wettability and the cellular reaction to implant surfaces are poorly understood determinants of implant biocompatibility. The aim of this study was to evaluate the in-vitro characteristics of a range of commercial available implants using a macrophage based assay of implant biocompatibility and a quantitative assessment of wettability and texture. Thirteen commercially available surfaces were subjected to wettability and texture characterisation using scanning and laser confocal microscopy. THP-1 macrophages were cultured on their surfaces and assessed using Integrin αV immunocytochemistry, SEM and RT-PCR for the expression of TNF-Alpha, IL-6, IL-10 and a cytokine array for the production of TNF-alpha, IL-10, IL-1RA and IL1β; important indicators of inflammation and macrophage polarization. Textured surfaces can be accurately sub-categorized dependent upon roughness and re-entrant features into four main types (macro, micro, meso and nano-textured surfaces). Significant (P based on roughness and present a macrophage based assay of breast implant biocompatibility with a quantitative assessment of implant wettability and texture. The breast implant surface-cell interaction is variable and sufficient to alter healing response and capsular contracture fate in-vivo. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    Full Text Available BackgroundBreast projection is a critical element of breast reconstruction aesthetics, but little has been published regarding breast projection as the firm expander is changed to a softer implant. Quantitative data representing this loss in projection may enhance patient education and improve our management of patient expectations.MethodsFemale patients who were undergoing immediate tissue-expander breast reconstruction with the senior author were enrolled in this prospective study. Three-dimensional camera software was used for all patient photographs and data analysis. Projection was calculated as the distance between the chest wall and the point of maximal projection of the breast form. Values were calculated for final tissue expander expansion and at varying intervals 3, 6, and 12 months after implant placement.ResultsFourteen breasts from 12 patients were included in the final analysis. Twelve of the 14 breasts had a loss of projection at three months following the implant placement or beyond. The percentage of projection lost in these 12 breasts ranged from 6.30% to 43.4%, with an average loss of projection of 21.05%.ConclusionsThis study is the first prospective quantitative analysis of temporal changes in breast projection after expander-implant reconstruction. By prospectively capturing projection data with three-dimensional photographic software, we reveal a loss of projection in this population by three months post-implant exchange. These findings will not only aid in managing patient expectations, but our methodology provides a foundation for future objective studies of the breast form.

    After initially successful preservation of residual hearing with cochlear implantation, some patients experience subsequent delayed hearing loss. The etiology of such delayed hearing loss is unknown. Human temporal bone pathology is critically important in investigating the etiology, and directing future efforts to maximize long term hearing preservation in cochlear implant patients. Here we present the temporal bone pathology from a patient implanted during life with an Iowa/Nucleus Hybrid S8 implant, with initially preserved residual hearing and subsequent hearing loss. Both temporal bones were removed for histologic processing and evaluated. Complete clinical and audiologic records were available. He had bilateral symmetric high frequency severe to profound hearing loss prior to implantation. Since he was implanted unilaterally, the unimplanted ear was presumed to be representative of the pre-implantation pathology related to his hearing loss. The implanted and contralateral unimplanted temporal bones both showed complete degeneration of inner hair cells and outer hair cells in the basal half of the cochleae, and only mild patchy loss of inner hair cells and outer hair cells in the apical half. The total spiral ganglion neuron counts were similar in both ears: 15,138 (56% of normal for age) in the unimplanted right ear and 13,722 (51% of normal for age) in the implanted left ear. In the basal turn of the implanted left cochlea, loose fibrous tissue and new bone formation filled the scala tympani, and part of the scala vestibuli. Delayed loss of initially preserved hearing after cochlear implantation was not explained by additional post-implantation degeneration of hair cells or spiral ganglion neurons in this patient. Decreased compliance at the round window and increased damping in the scala tympani due to intracochlear fibrosis and new bone formation might explain part of the post-implantation hearing loss.

  17. Reducing infection risk in implant-based breast-reconstruction surgery: challenges and solutions

    Science.gov (United States)

    Ooi, Adrian SH; Song, David H

    2016-01-01

    Implant-based procedures are the most commonly performed method for postmastectomy breast reconstruction. While donor-site morbidity is low, these procedures are associated with a higher risk of reconstructive loss. Many of these are related to infection of the implant, which can lead to prolonged antibiotic treatment, undesired additional surgical procedures, and unsatisfactory results. This review combines a summary of the recent literature regarding implant-related breast-reconstruction infections and combines this with a practical approach to the patient and surgery aimed at reducing this risk. Prevention of infection begins with appropriate reconstructive choice based on an assessment and optimization of risk factors. These include patient and disease characteristics, such as smoking, obesity, large breast size, and immediate reconstructive procedures, as well as adjuvant therapy, such as radiotherapy and chemotherapy. For implant-based breast reconstruction, preoperative planning and organization is key to reducing infection. A logical and consistent intraoperative and postoperative surgical protocol, including appropriate antibiotic choice, mastectomy-pocket creation, implant handling, and considered acellular dermal matrix use contribute toward the reduction of breast-implant infections.

    Multiple studies have reported on the safety of nipple-sparing mastectomy and low complication rates associated with single-stage implant breast reconstruction. Yet many plastic surgeons continue to be resistant to change. This article presents the senior author's (M.A.C.) experience during his transition period from the latissimus dorsi flap with adjustable implants to a "one-and-done" approach using shaped implants and fetal bovine acellular dermal matrix. A literature review was performed selecting articles discussing single-stage implant reconstruction, indications, outcomes, technique, and complications. Additional articles were selected after review of the references of identified articles. Clinical pearls discussed include patient selection, implant selection, and mastectomy incision choices, with a detailed description of the senior author's operative technique. Twenty-seven single-stage implant reconstructions were performed. Average mastectomy weight was 343.82 g. The average implant volume was 367 cc. Shaped implants were most commonly used. Acellular dermal matrix was used in all breasts. Complications included erythema requiring intravenous antibiotics (three patients), skin ischemia caused by methylene blue (one patient), seroma (one patient), unilateral partial nipple necrosis (one patient), mastectomy skin necrosis (one patient), and exposed/infected implants that were salvaged using a sequential irrigation protocol described by Sforza et al. in 2014 (two patients). Breast reconstruction after mastectomy has evolved toward less invasive, single-stage procedures. Aesthetic refinements include nipple-sparing mastectomy, use of acellular dermal matrix, shaped implants, and fat grafting. Selected patients will benefit from a one-and-done breast implant reconstruction with no additional oncologic risk. Surgeons must embrace the change and provide their patients with a procedure that will offer the best aesthetic outcomes. Therapeutic, IV.

    This study investigated the clinicopathologic characteristics and survival of women diagnosed with pregnancy-associated breast cancer (PABC) in Taiwan. PABC is defined as breast cancer diagnosed during pregnancy or within 1 year after obstetric delivery. Our sample of PABC patients (N = 26) included all patients diagnosed at a major medical center in northern Taiwan from 1984 through 2009. Among these patients, 15 were diagnosed during pregnancy and 11 were diagnosed within 1 year after delivery. The comparison group included 104 patients within the same age range as the PABC patients and diagnosed with breast cancer not associated with pregnancy from 2004 through 2009 at the same hospital. Patients' initiating treatment delayed, 5-year and 10-year overall survival were delineated by stratified Kaplan-Meier estimates. Patients' characteristics were associated with initiating treatment delayed was evaluated with multivariate proportional hazards modeling. Antepartum PABC patients were younger and had longer time between diagnosis and treatment initiation than postpartum PABC patients. The predictor of treatment delayed was including birth parity, cancer stage, and pregnancy. The PABC group had larger tumors, more advanced cancer stage, and tumors with less progesterone receptor than the comparison group. The antepartum PABC patients had higher mortality than postpartum PABC and comparison groups within 5 years after diagnosis. Based on these results, we confirmed that pregnant women with breast cancer were more likely to delay treatment. Therefore, we recommend that breast cancer screening should be integrated into the prenatal and postnatal routine visits for early detection of the women's breast problems.

    Anaplastic large cell lymphoma (ALCL) of the breast is a very rare nonepithelial neoplasm. In the literature, this tumor has sometimes been described in proximity of breast implants (60 implant-related ALCL reported). In 2010, a patient who had undergone a right mastectomy and tissue expander/implant reconstruction for a "ductal" carcinoma 10 years before was referred to our unit for evaluation. On examination, an enlarged reconstructed right breast was found. The reconstructed breast did not show tenderness or signs of infection, ulceration, or breakdown. Mammograms and ultrasound scan did not suggest the presence of recurrent cancer, infection, deflation of the implant, or severe capsule contracture. The patient underwent mammary implant replacement. About 3 weeks after surgery, the patient came back to our unit for a new mild enlargement of the operated breast and the implant was removed. Three months later, the patient returned with a skin lesion in the right parasternal region. A radical excisional biopsy was performed under local anesthesia and the diagnosis of ALK-1-negative ALCL was finally made. The clinical and histological diagnosis of this disease is difficult as it can often be mistaken for a simple seroma (breast enlargement), an infection, or an unspecific reaction to silicone (redness and/or tension of the skin, itching, and fever). We strongly suggest considering ALCL in any patient with a spontaneous breast seroma lasting more than 6 months after mammary prosthesis implantation. The suspicion of ALCL must be suggested to the pathologist immediately. This journal requires that authors assign a level of evidence to each article.

    Unusual and probably underestimated complications following breast reconstruction with a latissimus dorsi (LD) flap and sub-pectoral implant are the LD muscle twitching and the breast contour deformities from pectoralis major (PM) muscle contraction. Surgical muscle denervation is usually indicated for these complications. Botulinum toxin A (BTX-A) infiltration has been described in reducing breast contour deformity in sub-pectoral implant after breast augmentation or reconstruction. Between January 2002 and April 2006, 71 consecutive patients underwent delayed unilateral breast reconstructions with LD flap and sub-pectoral implant after mastectomy. All patients reporting discomforting signs and symptoms from muscle contraction in the reconstructed breast were included in this prospective study. Thirteen patients (18.3%) were selected and treated with BTX-A percutaneous local injections. Signs and symptoms were evaluated, after 4, 8 and 12 months, by the patients and by a panel of three physicians not involved in the study, using a five-point scale. During the study period all patients reported a decrease or disappearance of the signs and symptoms. After 12 months, 11 patients received three BTX-A infiltrations, demonstrating considerable improvements compared to the pre-treatment status. Wilcoxon matched pairs rank sum test showed a statistical difference between pre-treatment and post-treatment scores after 14 days (P<0.01) and 12 months (P<0.001). Our experience shows that muscular contraction deformities after breast reconstruction with a LD flap plus implant are not uncommon complications. The use of BTX-A infiltrations is an effective, not surgical, low cost and low risk procedure to treat these complications. It is an easy procedure to be performed on an outpatient basis with a temporary effect but safely repeatable and reproducible; it avoids hospitalisation or further surgical procedures and demonstrates tolerable latency with satisfactory outcomes.

    The aim of this study was to assess why women delay in getting treatment (i.e. surgery) for breast cancer, as well as to explore on what type of issues are involved in such delay cases. Basic interpretative of qualitative methodology was applied to construct the reality of delay phenomena, and its interaction with social worlds. Six themes were identified: new conception of breast cancer treatment, psychological defenses, health support system, symtomatology experience, model and barriers. The delay issue in breast cancer requires attention as a multidimensional problem as this will facilitate more comprehensive and effective intervention to reduce delay.

    Immediate implant-based breast reconstruction followed by postmastectomy radiation therapy (PMRT) is controversial because of the risk of compromised treatment plans and concerns regarding cosmetic outcomes. We evaluated the effects of immediate direct-to-implant breast reconstruction with anatomical implants on the quality of PMRT delivered by 3-dimensional conformal radiotherapy (3D-CRT). In this retrospective, single-institution study, patients who had undergone reconstruction with direct anatomic implant, performed by a single surgeon, received 3D-CRT between 2008 and 2013. For each patient, 2 plans (including or excluding internal mammary nodes [IMN]) were created and calculated. The primary end point was the dose distribution among reconstructed breasts, heart, lungs, and IMNs, and between right and left breasts. Of 29 consecutive patients, 11 received right-sided and 18 received left-sided PMRT to a total dose of 50 Gy. For plans excluding IMN coverage, mean D{sub mean} for right and left reconstructed breasts was 49.09 Gy (98.2% of the prescribed dose) and 48.51 Gy (97.0%), respectively. For plans including IMNs, mean D{sub mean} was 49.15 Gy (98.3%) for right and 48.46 Gy (96.9%) for left reconstructed breasts; the mean IMN D{sub mean} was 47.27 Gy (right) and 47.89 Gy (left). Heart D{sub mean} was below 1.56 Gy for all plans. Mean total lung volume receiving a dose of ≥ 20 Gy was 13.80% to 19.47%. PMRT can be delivered effectively and safely by 3D-CRT after direct-to-implant breast reconstruction with anatomical implants, even if patients require IMN treatment.

    Capsular contracture is the most common and frustrating complication in women who have undergone breast implantation. Its cause and, accordingly, treatment and prevention remain to be elucidated fully. The aim of this prospective observational pilot study was to test the hypothesis that the presence of bacteria on breast implants is associated with capsular contracture. We prospectively studied consecutive patients who underwent breast implant removal for reasons other than overt infection at the Mayo Clinic from February through September 2008. Removed breast implants were processed using a vortexing/sonication procedure and then subjected to semiquantitative culture. Twenty-seven of the 45 implants collected were removed due to significant capsular contracture, among which 9 (33%) had ≥20 CFU bacteria/10 ml sonicate fluid; 18 were removed for reasons other than significant capsular contracture, among which 1 (5%) had ≥20 CFU/10 ml sonicate fluid (P = 0.034). Propionibacterium species, coagulase-negative staphylococci, and Corynebacterium species were the microorganisms isolated. The results of this study demonstrate that there is a significant association between capsular contracture and the presence of bacteria on the implant. The role of these bacteria in the pathogenesis of capsular contracture deserves further study. PMID:19261794

    Full Text Available Lymphedema is a common complication after mastectomy in breast cancer patients. Many treatment options are available, but no treatment results in a complete cure. We report a case of lymphedema that occurred after modified radical mastectomy in a breast cancer patient who showed objective improvement after delayed breast reconstruction with an latissimus dorsi myocutaneous flap. A 41-year-old female patient with left breast cancer had undergone modified radical mastectomy with axillary lymph node dissection and postoperative radiotherapy 12 years previously. Four years after surgery, lymphedema developed and increased in aggravation despite conservative treatment. Eight years after the first operation, the patient underwent delayed breast reconstruction using the extended latissimus dorsi myocutaneous flap method. After reconstruction, the patient's lymphedema symptoms showed dramatic improvement by subjective measures including tissue softness and feeling of lightness, and by objective measures of about 7 mL per a week, resulting in near normal ranges of volume. At a postoperative follow-up after 3 years, no recurrence was observed. Delayed breast reconstruction with extended latissimus dorsi myocutaneous flaps may be helpful to patients with lymphedema after mastectomy. This may be a good option for patients who are worried about the possibility of the occurrence or aggravation of secondary lymphedema.

    Full Text Available Purpose: This article reports the clinical outcomes observed in a large number of patients receiving block bone allograft used for sinus augmentation and delayed implant placement. Patients and Methods: In total, 28 patients (13 males with a mean age of 49.8 ± 10.1 years (range: 33-67 years were included in this case series. All selected patients suffered from severe alveolar ridge atrophy in the posterior maxilla and required bone augmentation procedures, followed by implant placement after 6 months. All patients were followed for 18 months after the grafting, with scheduled monthly visits and/or more frequent visits if required. The survival rates for both the bone blocks and placed implants were then evaluated. Results: A total of 42 blocks and 90 implants were placed. Only one bone graft and 5 implants failed; the survival rate was 97.2% and 95.5% for the bone grafts and implants, respectively. The graft failed due to the onset of post-surgical infectious sinusitis, while in some patients′ implants showed absence of osteointegration at the end of the healing phase. Of note, all failed implants were observed in heavy smokers; in all other patients, blocks and implants were successful. Conclusions: This preliminary case series suggests that the grafting of bone allograft followed by delayed implant placement may be a promising strategy for sinus augmentation. More extended and larger follow-up studies are needed to confirm this preliminary data.

    Breast reconstruction has become standard of care for female patients with breast cancer. The transverse rectus abdominis musculo-cutaneous flap (TRAMf) is the most common method of immediate or delayed autologous breast reconstruction following mastectomy. We share our experience with modified, double back cut of post-mastectomy skin in delayed pedicled TRAMf breast reconstruction, resulting in fish-shaped skin paddle. This sort of back cut is a simple, reliable way to obtain a natural, esthetically pleasant breast mound with inconspicuous hidden scars.

    Outcome studies of immediate implant-based breast reconstruction have focused largely on patient factors, whereas the relative impact of the surgeon as a contributing variable is not known. As the procedure requires collaboration of both a surgical oncologist and a plastic surgeon, the effect of the surgeon team interaction can have a significant impact on outcome. This study examines outcomes in implant-based breast reconstruction and the association with patient characteristics, surgeon, and surgeon team familiarity. A retrospective review of 3142 consecutive implant-based breast reconstruction mastectomy procedures at one institution was performed. Infection and skin necrosis rates were measured. Predictors of outcomes were identified by unadjusted logistic regression followed by multivariate logistic regression. Surgeon teams were grouped according to number of cases performed together. Patient characteristics remain the most important predictors for outcomes in implant-based breast reconstruction, with odds ratios above those of surgeon variables. The authors observed significant differences in the rate of skin necrosis between surgical oncologists with an approximately two-fold difference between surgeons with the highest and lowest rates. Surgeon teams that worked together on fewer than 150 procedures had higher rates of infection. Patient characteristics are the most important predictors for surgical outcomes in implant-based breast reconstruction, but surgeons and surgeon teams are also important variables. High-volume surgeon teams achieve lower rates of infection. This study highlights the need to examine modifiable risk factors associated with optimum implant-based breast reconstruction outcomes, which include patient and provider characteristics and the surgical team treating the patient.

    This study aimed to investigate whether breast volume measured preoperatively using a Kinect 3D sensor could be used to determine the most appropriate implant size for reconstruction. Ten patients underwent 3D imaging before and after unilateral implant-based reconstruction. Imaging used seven configurations, varying patient pose and Kinect location, which were compared regarding suitability for volume measurement. Four methods of defining the breast boundary for automated volume calculation were compared, and repeatability assessed over five repetitions. The most repeatable breast boundary annotation used an ellipse to track the inframammary fold and a plane describing the chest wall (coefficient of repeatability: 70 ml). The most reproducible imaging position comparing pre- and postoperative volume measurement of the healthy breast was achieved for the sitting patient with elevated arms and Kinect centrally positioned (coefficient of repeatability: 141 ml). Optimal implant volume was calculated by correcting used implant volume by the observed postoperative asymmetry. It was possible to predict implant size using a linear model derived from preoperative volume measurement of the healthy breast (coefficient of determination R(2) = 0.78, standard error of prediction 120 ml). Mastectomy specimen weight and experienced surgeons' choice showed similar predictive ability (both: R(2) = 0.74, standard error: 141/142 ml). A leave one-out validation showed that in 61% of cases, 3D imaging could predict implant volume to within 10%; however for 17% of cases it was >30%. This technology has the potential to facilitate reconstruction surgery planning and implant procurement to maximise symmetry after unilateral reconstruction.

    1997-04-01

    Pelvic exenteration is one of the most radical procedures in the repertoire of gynecologic oncology procedures. Postoperative complications include sepsis, hemorrhage, formation of adhesions resulting in bowel obstruction, and fistulas resulting from large denuded pelvic surfaces. To date there is no clear consensus as to the best way to cover the pelvis after the destructive phase of an exenteration. Herein, we present a different approach to pelvic coverage by placement of a 300 cc saline breast implant. Use of a saline-filled breast implant to fill the pelvis represents a possible approach to addressing the denuded pelvic space created during extensive gynecologic surgery.

    The purpose of this study was to assess the diagnostic accuracy of MRI in detecting prosthesis integrity and malignancy after breast augmentation and reconstruction. Forty-one implants in 25 patients were analyzed by MRI before surgical removal. Imaging results were compared with ex vivo findings. Magnetic resonance imaging of the breast was performed on a 1.5-T system using a dedicated surface breast coil. Axial and sagittal T2-weighted fast spin-echo as well as dynamic contrast-enhanced T1-weighted gradient-recalled-echo sequences were acquired. The linguine sign indicating collapse of the silicone shell or siliconomas indicating free silicone proved implant rupture, whereas early focal contrast enhancement of a lesion was suspicious for malignancy. The sensitivity for detection of implant rupture was 86.7% with a specificity of 88.5%. The positive and negative predictive values were 81.3 and 92.0%, respectively. The linguine sign as a predictor of intracapsular implant rupture had a sensitivity of 80% with a specificity of 96.2%. Magnetic resonance imaging revealed two lesions with suspicious contrast enhancement (one carcinoma, one extra-abdominal fibromatosis). Magnetic resonance imaging is a reliable and reproducible technique for diagnosing both implant rupture and malignant lesions in women after breast augmentation and reconstruction. (orig.)

    Prosthetic-based breast reconstruction can be used in combination with autologous flaps such as a latissimus dorsi (LD) flap or a thoracodorsal artery perforator (TDAP) flap to achieve symmetry. However, the LD and TDAP flaps require a different skin incision from that which is used for the mastectomy. As a new autologous flap for use in combination with prosthetic-based breast reconstruction after nipple-sparing mastectomy (NSM), we used an inframammary adipofascial flap. The patient was a 27-year-old female with moderate ptotic breasts, who had ductal carcinoma in situ in the lower outer quadrant of her left breast. After NSM through the inframammary fold (IMF) incision, the subcutaneous fat of the intended inframammary area was undermined, and the tongue shaped adipofascial flap was pulled up in the intended area. After inserting a tissue expander under the major pectoral muscle, this adipofascial flap was reflected back to the inferior portion of the breast area. After modeling the breast mound with this flap, the inframammary skin incision was sutured. Eleven months later, the patient underwent surgery to replace the expander with a permanent implant. Eight months after the replacement with an implant, the cosmetic result is good. This procedure can be performed through the same skin incision on the IMF as NSM. Total breast reconstruction using the inframammary adipofascial flap with an implant can be an alternative approach to achieving symmetry in some patients. This method is useful for breast reconstruction after NSM for young patients with moderate-ptotic breasts. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Full Text Available This study investigated the clinicopathologic characteristics and survival of women diagnosed with pregnancy-associated breast cancer (PABC in Taiwan. PABC is defined as breast cancer diagnosed during pregnancy or within 1 year after obstetric delivery. Our sample of PABC patients (N = 26 included all patients diagnosed at a major medical center in northern Taiwan from 1984 through 2009. Among these patients, 15 were diagnosed during pregnancy and 11 were diagnosed within 1 year after delivery. The comparison group included 104 patients within the same age range as the PABC patients and diagnosed with breast cancer not associated with pregnancy from 2004 through 2009 at the same hospital. Patients' initiating treatment delayed, 5-year and 10-year overall survival were delineated by stratified Kaplan-Meier estimates. Patients' characteristics were associated with initiating treatment delayed was evaluated with multivariate proportional hazards modeling. Antepartum PABC patients were younger and had longer time between diagnosis and treatment initiation than postpartum PABC patients. The predictor of treatment delayed was including birth parity, cancer stage, and pregnancy. The PABC group had larger tumors, more advanced cancer stage, and tumors with less progesterone receptor than the comparison group. The antepartum PABC patients had higher mortality than postpartum PABC and comparison groups within 5 years after diagnosis. Based on these results, we confirmed that pregnant women with breast cancer were more likely to delay treatment. Therefore, we recommend that breast cancer screening should be integrated into the prenatal and postnatal routine visits for early detection of the women's breast problems.

  19. Two-Stage Latissimus Dorsi Flap with Implant for Unilateral Breast Reconstruction: Getting the Size Right

    Full Text Available BackgroundThe aim of unilateral breast reconstruction after mastectomy is to craft a natural-looking breast with symmetry. The latissimus dorsi (LD flap with implant is an established technique for this purpose. However, it is challenging to obtain adequate volume and satisfactory aesthetic results using a one-stage operation when considering factors such as muscle atrophy, wound dehiscence and excessive scarring. The two-stage reconstruction addresses these difficulties by using a tissue expander to gradually enlarge the skin pocket which eventually holds an appropriately sized implant.MethodsWe analyzed nine patients who underwent unilateral two-stage LD reconstruction. In the first stage, an expander was placed along with the LD flap to reconstruct the mastectomy defect, followed by gradual tissue expansion to achieve overexpansion of the skin pocket. The final implant volume was determined by measuring the residual expander volume after aspirating the excess saline. Finally, the expander was replaced with the chosen implant.ResultsThe average volume of tissue expansion was 460 mL. The resultant expansion allowed an implant ranging in volume from 255 to 420 mL to be placed alongside the LD muscle. Seven patients scored less than six on the relative breast retraction assessment formula for breast symmetry, indicating excellent breast symmetry. The remaining two patients scored between six and eight, indicating good symmetry.ConclusionsThis approach allows the size of the eventual implant to be estimated after the skin pocket has healed completely and the LD muscle has undergone natural atrophy. Optimal reconstruction results were achieved using this approach.

    Cochlear implant recipients show improved speech perception and music appreciation when residual acoustic hearing is combined with the cochlear implant. However, up to one third of patients lose their pre-operative residual hearing weeks to months after implantation, for reasons that are not well understood. This study tested whether this "delayed" hearing loss was influenced by the route of electrode array insertion and/or position of the electrode array within scala tympani in a guinea pig model of cochlear implantation. Five treatment groups were monitored over 12 weeks: (1) round window implant; (2) round window incised with no implant; (3) cochleostomy with medially-oriented implant; (4) cochleostomy with laterally-oriented implant; and (5) cochleostomy with no implant. Hearing was measured at selected time points by the auditory brainstem response. Cochlear condition was assessed histologically, with cochleae three-dimensionally reconstructed to plot electrode paths and estimate tissue response. Electrode array trajectories matched their intended paths. Arrays inserted via the round window were situated nearer to the basilar membrane and organ of Corti over the majority of their intrascalar path compared with arrays inserted via cochleostomy. Round window interventions exhibited delayed, low frequency hearing loss that was not seen after cochleostomy. This hearing loss appeared unrelated to the extent of tissue reaction or injury within scala tympani, although round window insertion was histologically the most traumatic mode of implantation. We speculate that delayed hearing loss was related not to the electrode position as postulated, but rather to the muscle graft used to seal the round window post-intervention, by altering cochlear mechanics via round window fibrosis.

    Objective: In breast reconstruction, decision of projection of silicone breast implant in tissue expander replacement is difficult because of the need to consider several parameters that cannot be expressed in accurate numerical form. The present study aimed at a quantitative analysis based on decreased projection of the reconstructed side compared with silicone breast implant projection and to develop a new method for simple and practical decision of silicone breast implant projection. Methods: Thirty-five patients who had mammary carcinoma and were treated with simple mastectomy, tissue expander insertion, and replacement with anatomical silicone breast implant from April 2013 to March 2016 were retrospectively identified. We recorded the projection of used silicone breast implant (Pi). The projections of reconstructed breast 6 months after silicone breast implant insertion (Pr) and that of the unaffected breast during silicone breast implant selection (Pu) were measured. The difference between Pi and Pr was defined as the revised numerical value (Rev). We investigated whether Rev significantly differed according to age, body mass index, or Pu and analyzed correlations between Rev and age, Pu, and body mass index. Results: Mean Rev in all patients was 1.2 ± 0.3 cm. Rev was significantly higher in patients with higher body mass index than in those with lower body mass index (P < .01) and in patients with higher Pu than in those with lower Pu (P < .01). Significant positive correlations of Rev with body mass index and Pu were found (β = .63, P < .01 and β = .67, P < .01, respectively). Conclusions: Rev was a simple, practical, and cost-effective concept. We believe that it is a useful indicator for deciding silicone breast implant projection.

    Conclusions: Both shaped and round silicone gel devices can result in natural aesthetic outcomes. Shaped devices are preferred for contouring the upper pole and for optimizing breast projection. Round devices are preferred when the upper pole is not deficient and the patient desires softer breasts. Longer follow-up studies will be necessary.

    2011-04-01

    Full Text Available Pneumonitis is a rare but serious complication associated with paclitaxel and/or trastuzumab treatment. We report a 51-year-old female patient with locally advanced breast cancer who presented with shortness of breath, fever, dry cough and pulmonary infiltrates. She had been treated without complications for 10 weeks with paclitaxel (Taxol® and trastuzumab (Herceptin® as neoadjuvant therapy, with complete clinical and pathological response. Infections and cardiomyopathy were excluded as causes of her symptoms. Bronchoscopy and biopsy were performed and a diagnosis of drug-induced interstitial pneumonitis was made. After treatment with steroids, the patient showed a significant response in less than 24 h; she was discharged home without the need for oxygen less than 48 h after therapy initiation. Although no causative association could be found between either trastuzumab or paclitaxel and this patient’s pulmonary syndrome, the potential for such toxicity should be considered, especially as paclitaxel/trastuzumab is a vey common combination therapy for breast cancer.

    2016-03-26

    Introduction Anaplastic large cell lymphoma is a very rare T-cell lymphoma that has only recently been found to be associated with breast implants. It has been described in the literature mainly in the form of case reports. This article focuses on the imaging characteristics of this rare disease. We hope to increase awareness of breast imagers and referring physicians to improve early detection rates. Case Report We present the case of a 32-year-old female who presented with several weeks of pain and firmness in her right breast. MRI and ultrasound demonstrated a peri-implant fluid collection. Ultrasound-guided aspiration revealed anaplastic large cell lymphoma. The patient was treated with implant removal alone and has now been in remission for 3 years.  Conclusion Anaplastic large cell lymphoma of the breast is a very rare entity that has mainly been described in the literature as case reports. As in the case of our patient, imaging findings can be very non-specific, and it is important for surgeons, breast imagers, and oncologists to be aware of this rare disease to ensure prompt diagnosis.

    Full Text Available Lymphedema is a common complication after mastectomy in breast cancer patients. Manytreatment options are available, but no treatment results in a complete cure. We report acase of lymphedema that occurred after modified radical mastectomy in a breast cancerpatient who showed objective improvement after delayed breast reconstruction with anlatissimus dorsi myocutaneous flap. A 41-year-old female patient with left breast cancer hadundergone modified radical mastectomy with axillary lymph node dissection and postoperativeradiotherapy 12 years previously. Four years after surgery, lymphedema developed andincreased in aggravation despite conservative treatment. Eight years after the first operation,the patient underwent delayed breast reconstruction using the extended latissimus dorsimyocutaneous flap method. After reconstruction, the patient’s lymphedema symptomsshowed dramatic improvement by subjective measures including tissue softness and feeling oflightness, and by objective measures of about 7 mL per a week, resulting in near normal rangesof volume. At a postoperative follow-up after 3 years, no recurrence was observed. Delayedbreast reconstruction with extended latissimus dorsi myocutaneous flaps may be helpful topatients with lymphedema after mastectomy. This may be a good option for patients who areworried about the possibility of the occurrence or aggravation of secondary lymphedema.

    Full Text Available Acellular dermal matrix (ADM implant-based reconstructions have transformed direct-to-implant breast reconstruction (DTI. But like all surgery, it is not deplete of complications such as seroma, infections and wound healing problems. These are cited with varying frequencies in the literature. With increased experience and through a series of measures instituted to minimize complications, we have been able to improve outcomes for our patients. We report our technical refinements for prevention of ADM reconstruction associated complications including patient selection, implant selection, drains, dressing and our post operative antibiotic regime. We also outline our protocol for the management of ADM associated complications including seroma, simple and complex infection and red breast syndrome, such that the sequelae of complications are minimized and patients achieve a better long-term outcome.

    Capsular contracture remains a hitherto unsolved complication after implantation of silicone gel-filled breast prostheses. Based on clinical and experimental data, the use of an acellular dermal matrix as a sheath around implants may lead to lesser capsular contracture acting as a proposed biological environment mimicking wound bed tissue. The aim of our study was to analyse the tissue reaction after implantation of silicone prosthesis with and without an envelope of acellular dermal matrix. Implantation of 60 silicone prostheses in the back of Lewis rats were carried out, randomly paired taking one rat from group A and one from group B. Group A included implants completely enveloped with xenogenic acellular dermis and group B undraped silicone implants. At 3, 6 and 12 weeks postoperatively, the samples were explanted and subjected to histological and immunohistochemical evaluation. A new myofibroblast tissue layer was identified in proximity to the implant in both groups. The thickness of the layer in group A was continuously thinner than in group B regarding the different explantation time points. Implants completely wrapped with acellular dermal matrix showed significantly lesser inflammatory signs at 3 and 12 weeks after implantation compared to controls. Cell proliferation after 12 weeks was significantly decreased in group A. The slight myofibroblast layer and reduced rate of inflammation and proliferation in the treatment group show a positive effect of total acellular dermal matrix envelope and hypothesise the decrease of capsular contracture in long-term periods.

    2011-06-01

    This study aimed to evaluate the influence of labial alveolar bone thickness and the corresponding vertical bone loss on postoperative gingival recessions around anterior maxillary dental implants. Using cone beam computed tomography (CBCT) scanning, the temporal changes of three-dimensional images of alveolar bone were monitored to determine hard and soft tissue outcomes of two different implant placement techniques: delayed two-stage and immediate placement. Furthermore, for the delayed two-stage placement, guided bone regeneration was applied using either nonresorbable or resorbable membranes combined with anorganic bovine bone matrix. The comparative results suggested that gingival recessions were significantly lower in delayed two-stage placement, especially when using a nonresorbable membrane, compared to immediate placement, and labial bone thickness, measured by CBCT, offered an effectual indicator to assess gingival recession in the anterior region.

    The objective of this study was to evaluate the impact of breast implant surgery and its approaches on lactation by comparing women with and without breast implants at the time of childbirth. Between April of 2013 and July of 2014, in Rosario (Sanatorio de la Mujer and Centro Quirúrgico Rosario), Argentina, a prospective cohort study of women with and without breast implants was performed. Of a total of 3950 births that occurred during this period, 200 patients with similar anthropometric characteristics (maternal and newborn) were selected. Breastfeeding (exclusive or mixed) was compared with artificial feeding at 24 and 48 hours and 30 days in both groups, and the type of incision was also compared. Breastfeeding at 30 days showed a nonsignificant trend favoring the control group (OR, 7.39; 95 percent CI, 0.92 to 339.2). The percentage of women with implants who succeeded in establishing breastfeeding (exclusive or mixed) was very high (93 percent). In the control group, 99 percent of the women were breastfeeding at 30 days. In a comparison of the submammary and areola incision, breastfeeding showed odds ratios of 0.78 (95 percent CI, 0.33 to 1.87) at 24 hours, 1.10 (95 percent CI, 0.48 to 2.56) at 48 hours, and 0.18 (95 percent CI, 0.36 to 1.82) at 30 days. This study shows that most patients with breast implants were able to establish breastfeeding. However, there is a higher number of women without implants that established exclusive breastfeeding. No significant difference was found between the different surgical approaches. Therapeutic, II.

    Implant-based breast reconstructions can result in unsatisfactory results requiring surgical revision or salvage reconstructive surgery with autologous tissue. This study compares the outcomes and complications of salvage (tertiary) flap reconstruction after failed prosthesis placement to those of primary/secondary flap reconstruction. All patients undergoing free flap breast reconstruction after failed prosthesis between July 1, 2005, and June 30, 2014, were identified. A matched number of patients who underwent a de novo free flap breast reconstruction were selected randomly for review. The indication for prosthesis removal, demographic and operative data, flap type and inset, and complication rates were evaluated. Eighty-nine women with a history of failed implant-based reconstruction required free flap reconstruction for salvage in 121 breasts. Capsular contracture was the most common indication for prosthesis removal (62.0 percent). Recipient vessel scarring was 5.23 times more likely to occur in the prior prosthesis group (p breast reconstruction with autologous tissue after failed prosthesis can be safely performed, with success rates similar to those of primary free flap breast reconstruction. However, these procedures may have increased complexity because of recipient vessel scarring, higher rates of prior radiation therapy, and major complications, which may warrant appropriate preoperative planning and patient counseling.

    Surgical-site infection causes devastating reconstructive failure in implant-based breast reconstructions. Large national database studies offer insights into complication rates, but only capture outcomes within 30 days postoperatively. This study evaluates both early and late surgical-site infection in immediate implant-based reconstruction and identifies predictors. As part of the Mastectomy Reconstruction Outcomes Consortium Study, 1662 implant-based breast reconstructions in 1024 patients were evaluated for early versus late surgical-site infection. Early surgical-site infection was defined as infection occurring within 30 days postoperatively; late surgical-site infection was defined as infection occurring 31 days to 1 year postoperatively. Minor infection required oral antibiotics only, and major infection required hospitalization and/or surgical treatment. Direct-to-implant patients had 1-year follow-up, and tissue expander patients had 1-year post-exchange follow-up. Among 1491 tissue expander and 171 direct-to-implant reconstructions, overall surgical-site infection rate for tissue expander was 5.7 percent (85 of 1491) after first-stage, 2.5 percent (31 of 1266) after second-stage, and 9.9 percent (17 of 171) for direct-to-implant reconstruction. Over 47 to 71 percent of surgical-site infection complications were late surgical-site infection. Multivariate analysis identified radiotherapy and increasing body mass index as significant predictors of late surgical-site infection. No significant difference between the direct-to-implant and tissue expander groups in the occurrence of early, late, or overall surgical-site infection was found. The majority of surgical-site infection complications in immediate implant-based breast reconstructions occur more than 30 days after both first-stage and second-stage procedures. Radiotherapy and obesity are significantly associated with late-onset surgical-site infection. Current studies limited to early complications do

    Immediate tissue expander/implant-based breast reconstruction (BR) is often avoided when post-mastectomy radiotherapy (PMRT) is planned due to concerns about high complication rates and poor aesthetic outcomes. This study evaluated surgical, aesthetic and quality of life (QoL) outcomes in women undergoing immediate implant-based BR (IIBR) followed by PMRT. Participants were recruited at least six months after completing the final stage of BR. They completed validated on-line questionnaires assessing satisfaction, QoL, distress, body image and regret. Aesthetic outcomes were rated by their operating surgeon through clinical examination and assessed by an independent surgeon using photographs. Forty-seven participants completed questionnaires and reported good outcomes for QoL (FACT-B = 115; TOI = 73), satisfaction (Breast-Q), distress (Impact of Events scale women are willing to accept the potential risks of IIBR in exchange for its benefits including enhanced body image during chemotherapy and PMRT and the possible avoidance of more complicated and costly delayed autologous BR. The results support the importance of access to BR, even in women with high-risk disease. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Postmastectomy breast reconstruction is an important component of breast cancer care, but few receive it at the time of the mastectomy. Virtually nothing is known about receipt of reconstruction after initial cancer therapy and why treatment might be delayed. A 5-year follow-up survey was mailed to a population-based cohort of mastectomy-treated breast cancer patients who were initially surveyed at time of diagnosis in 2002 and reported to the Los Angeles and Detroit SEER registries (N = 645, response rate 60%). Outcomes were receipt of reconstruction (immediate [IR], delayed [DR], or none) and patient appraisal of their treatment decisions. About one-third (35.9%) had IR, 11.5% had DR, and 52.6% had no reconstruction. One-third delayed reconstruction because they focused more on other cancer interventions, and nearly half were concerned about surgical complications and interference with cancer surveillance. Two-thirds of those with no reconstruction said that the procedure was not important to them. A large proportion of all patients were satisfied with their reconstruction decision-making (89.4% IR, 78.4% DR, 80.4% no reconstruction, P = NS). However, only 59.3% of those with no reconstruction felt that they were adequately informed about their reconstructive options (vs 82.7% IR and 78.4% DR, P breast reconstruction after initial cancer treatment. Factors associated with delayed reconstruction were primarily related to uncertainty about the procedure, concern about cancer surveillance, and low priority. Those without reconstruction demonstrated significant informational needs, which should be addressed with future research efforts.

    An estimated 1-3% of all women in the Netherlands carry breast implants. Since the introduction five decades ago, problems with a variety of breast implants have emerged with direct consequences for the patients' health. Plastic surgeons worldwide reacted through campaigning for auditing on long-term implant quality, surgeon performance, and institutional outcomes in implant registries. Especially, the PIP implant scandal of 2010 demonstrated the paucity of epidemiological data and uncovered a weakness in our ability to even 'track and trace' patients. In addition, a recent report of the Dutch Institute of National Health showed a lack of compliance of 100% of breast implant producers to CE requirements. These arguments stress the need for an independent implant registry. Insufficient capture rates or dependence from the implant producers made the variety of national and international patient registries unreliable. The Dutch Breast Implant Registry (DBIR) is unique because it is an opt-out registry without the need for informed consent and thus a high capture rate. Furthermore, an estimated 95% of breast implants are implanted by board-certified plastic surgeons. Funding was received from a non-governmental organisation to increase the quality of health care in the Netherlands, and maintenance is gathered by 25 euros per implant inserted. This article describes the way the Dutch have set up their system, with special attention to the well-known hurdles of starting a patient registry. Examples include: funding, medical ethical issues, opt out system, benchmarking, quality assurance as well as governance and collaboration. The Dutch consider their experience and data shareware for others to be used globally to the benefit of patient safety and quality improvement.

    Background Breast conserving surgery (BCS) has been the standard surgical procedure for the treatment of early breast cancer. Endoscopic subcutaneous mastectomy (ESM) plus immediate reconstruction with implants is an emerging procedure. The objective of this prospective study was to evaluate the clinical outcomes of these two surgical procedures in our clinical setting.Methods From March 2004 to October 2007, 43 patients with breast cancer underwent ESM plus axillary lymph node dissection and immediate reconstruction with implants, while 54 patients underwent BCS. The clinical and pathological characteristics, surgical safety, and therapeutic effects were compared between the two groups. Results There were no significant differences in the age, clinical stage, histopathologic type of tumor, operative blood loss, postoperative drainage time, and postoperative complications between the two groups (P>0.05).The postoperative complications were partial necrosis of the nipple and superficial skin flap in the ESM patients, and hydrops in the axilla and residual cavity in the BCS patients. There was no significant difference in the rate of satisfactory postoperative cosmetic outcomes between the ESM (88.4%, 38/43) and BCS (92.6%, 50/54) patients (P>0.05). During follow-up of 6 months to 4 years, all patients treated with ESM were disease-free, but 3 patients who underwent BCS had metastasis or recurrence-one of these patients died of multiple organ metastasis.Conclusions After considering the wide Indications for use, high surgical safety, and favorable cosmetic outcomes, we conclude that ESM plus axillary lymph node dissection and immediate reconstruction with implants-the new surgery of choice for breast cancer-warrants serious consideration as the prospective next standard surgical procedure.

  1. Obesity-related Risk Factors in Implant-based Breast Reconstruction Using AlloDerm

    Coleman, Cathryn A.; Erickson, Stephen W.

    2017-01-01

    With a population in which 70% of the patients were overweight or obese, we reviewed retrospectively 135 breasts of 70 consecutive patients who underwent implant-based immediate breast reconstruction using freeze-dried AlloDerm as the acellular dermal matrix. Several obesity-related parameters were evaluated to determine their possible correlation to early postoperative complications. We found that breast width and surface area of AlloDerm usage correlated with the development of infection and mastectomy skin flap necrosis. Increased breast width and size of AlloDerm matrix implanted were correlated with higher rates of both minor and significant skin necrosis and of cellulitis. Body mass index was correlated with the development of cellulitis and minor and major skin necrosis but not with seroma or reconstruction failure. Preexisting breast cup size correlated with the development of seroma but not the other complications. We observed no statistically significant association between reconstruction failure and any of the parameters reviewed, but this is likely due to the small number of failures in our data set (n = 10).

    We present our use of magnetic resonance (MR) measurement to determine the amount of residual breast tissue (RBT) following total mastectomy with reconstruction. Breast MR images of 45 women who underwent surgery between January and November 2011 were reviewed. The cohort included therapeutic and prophylactic mastectomies. RBT was evaluated at four points with a digital caliper assessing T2-weighted and T1-weighted images. Patients undergoing mastectomy for carcinoma tended to have less RBT than in prophylactic surgery. Greater age and recent surgery both correlated with larger RBT. Variable thickness of RBT is demonstrable following mastectomy and implant reconstruction using MR imaging. Copyright © 2015 Elsevier Inc. All rights reserved.

    2015-06-01

    Breast animation may be an unfortunate result of subpectoral implant-based reconstruction following mastectomy. This article reviews a novel approach to the treatment of animation deformity in cases of reconstruction, whereby the pectoralis major muscle is sutured down to the chest wall and the implant is transferred to the subcutaneous plane. A retrospective review was performed on 19 breasts undergoing pocket change. In selected cases, fat grafting was added to augment the soft-tissue framework around the implant. Demographics, operative details, outcomes, and complications were recorded. All 19 breasts had complete resolution of their animation deformity. Complications were seen in five breasts (26.3 percent). Four breasts (21.1 percent) developed Baker grade III or IV capsular contracture requiring capsulectomy that was curative. One seroma (5.3 percent) required in-office drainage. There were no visible implant deformities, infections, or implant removals. In appropriately selected patients, pocket change to a subcutaneous plane is a safe and effective technique for correction of severe animation deformity following implant-based breast reconstruction.

    This study compared the presurgical psychosocial and functional status of 238 women seeking breast reconstruction, either at the time of their mastectomy (immediate) (n = 151) or after prior mastectomy (delayed) (n = 87). Delayed subjects were further categorized in groups of time-since-mastectomy to examine the effects of time on postmastectomy psychosocial adjustment. Presurgical measures of quality of life, psychological distress, and somatic anxiety were obtained. The results revealed relative impairment of quality of life and psychosocial functioning for immediate compared with delayed subjects. Immediate subjects reported greater disturbance in general mental health functioning, more severe impairment in emotional well being related to their cancer diagnosis, and higher levels of anxiety. Immediate subjects also reported a trend toward greater disturbance in work and daily activities, more frequent interference in social activities, and less vitality. Similarly, it was noted that the immediate group reported greater impairment in physical and functional well being related to their cancer adjustment. On psychological assessment, immediate subjects were more likely to report higher levels of affective distress, depressive symptoms, and obsessive-compulsive traits. For the delayed group, no statistically significant differences in the dependent measures were obtained when comparing subjects at 1 year, 2 years, and more than 2 years after mastectomy. Women seeking immediate reconstruction at the time of mastectomy show a relatively higher incidence of psychosocial impairment and functional disability. Women who undergo mastectomy demonstrate early restoration of psychosocial health within the first year after surgery. Patient preoperative psychosocial distress may have important implications for clinical decision-making and surgical outcome for women seeking combined mastectomy and breast reconstruction.

    2016-11-01

    The availability of acellular dermal matrix (ADM) and synthetic mesh products has prompted plastic surgeons to revisit subcutaneous implant-based breast reconstruction. The literature is limited, however, with regards to evidence on patient selection, techniques, and outcomes. A systematic review of the Medline and Cochrane databases was performed for original studies reporting breast reconstruction with ADM or mesh, and subcutaneous implant placement. Studies were analyzed for level of evidence, inclusion/exclusion criteria for subcutaneous reconstruction, reconstruction characteristics, and outcomes. Six studies (186 reconstructions) were identified for review. The majority of studies (66.7%) were level IV evidence case series. Eighty percent of studies had contraindications for subcutaneous reconstruction, most commonly preoperative radiation, high body mass index, and active smoking. Forty percent of studies commenting on patient selection assessed mastectomy flap perfusion for subcutaneous reconstruction. Forty-five percent of reconstructions were direct-to-implant, 33.3% 2-stage, and 21.5% single-stage adjustable implant, with ADM utilized in 60.2% of reconstructions versus mesh. Pooled complication rates included: major infection 1.2%, seroma 2.9%, hematoma 2.3%, full nipple-areola complex necrosis 1.1%, partial nipple-areola complex necrosis 4.5%, major flap necrosis 1.8%, wound healing complication 2.3%, explantation 4.1%, and grade III/IV capsular contracture 1.2%. Pooled short-term complication rates in subcutaneous alloplastic breast reconstruction with ADM or mesh are low in preliminary studies with selective patient populations, though techniques and outcomes are variable across studies. Larger comparative studies and better-defined selection criteria and outcomes reporting are needed to develop appropriate indications for performing subcutaneous implant-based reconstruction.

  12. Capsular contracture by silicone breast implants: possible causes, biocompatibility, and prophylactic strategies

    Full Text Available Andreas E Steiert, Maria Boyce, Heiko Sorg Department of Plastic, Hand and Reconstructive Surgery, Hannover Medical School, Hannover, Germany Abstract: The most common implanted material in the human body consists of silicone. Breast augmentation and breast reconstruction using silicone-based implants are procedures frequently performed by reconstructive and aesthetic surgeons. A main complication of this procedure continues to be the development of capsular contracture (CC, displaying the result of a fibrotic foreign body reaction after the implantation of silicone. For many years, experimental and clinical trials have attempted to analyze the problem of its etiology, treatment, and prophylaxis. Different theories of CC formation are known; however, the reason why different individuals develop CC in days or a month, or only after years, is unknown. Therefore, we hypothesize that CC formation, might primarily be induced by immunological mechanisms along with other reasons. This article attempts to review CC formation, with special attention paid to immunological and inflammatory reasons, as well as actual prophylactic strategies. In this context, the word “biocompatibility” has been frequently used to describe the overall biological innocuousness of silicone in the respective studies, although without clear-cut definitions of this important feature. We have therefore developed a new five-point scale with distinct key points of biocompatibility. Hence, this article might provide the basis for ongoing discussion in this field to reduce single-publication definitions as well as increase the understanding of biocompatibility.

    To evaluate and compare peri-implant health, marginal bone loss and success of immediate and delayed implant placement for rehabilitation with full-arch fixed prostheses. The present study was a prospective, randomized, single-blind, clinical preliminary trial. Patients were randomized into two treatment groups. In Group A implants were placed immediately post-extraction and in Group B six months after extraction. The following control time-points were established: one week, six months and twelve months after loading. Measurements were taken of peri-implant crevicular fluid volume, plaque index, gingival retraction, keratinized mucosa, probing depth, modified gingival index and presence of mucositis. Implant success rates were evaluated for the two groups. The study sample included fifteen patients (nine women and six men) with a mean average age of 63.7 years. One hundred and forty-four implants were placed: 76 placed in healed sites and 68 placed immediately. At the moment of prosthetic loading, keratinized mucosa width and probing depth were higher in immediate implants than delayed implants, with statistically significant differences. However, after six and twelve months, differences between groups had disappeared. Bone loss was 0.54 ± 0.39 mm for immediate implants and 0.66 ± 0.25 mm for delayed implants (p=0.201). No implants failed in either group. The present study with a short follow-up and a small sample yielded no statistically significant differences in implant success and peri-implant marginal bone loss between immediate and delayed implants with fixed full-arch prostheses. Peri-implant health showed no statistically significant differences for any of the studied parameters (crevicular fluid volume, plaque index, gingival retraction, keratinized mucosa, probing depth, modified gingival index and presence of mucositis) at the twelve-month follow-up.

    2017-09-01

    Full Text Available Fibromatosis of the breast is a rare benign disease compromising <0.2% of all primary breast tumors. Although the chest wall is a common location, occurrences of implant-associated fibromatosis of the breast are extremely rare; only 33 cases have been reported. We present a case of a 42-year-old female who underwent breast augmentation with silicone breast implants, and 2 years later developed an aggressive implant-associated fibromatosis of the breast and chest wall. On imaging studies, the tumor mimicked breast carcinoma, and despite chemotherapy, the fibromatosis rapidly enlarged and was locally invasive requiring wide surgical excision. Unlike previously reported imaging findings, magnetic resonance imaging revealed an oval circumscribed mass with fringe-like internal architecture. We provide a review of the literature and discuss the imaging features of implant-associated fibromatosis of the breast.

    Since the 2012 approval of shaped implants, their use in breast reconstruction has increased in the United States. However, large-scale comparisons of complications and patient-reported outcomes are lacking. The authors endeavored to compare surgical and patient-reported outcomes across implant types. The Mastectomy Reconstruction Outcomes Consortium database was queried for expander/implant reconstructions with at least 1-year postexchange follow-up (mean, 18.5 months). Outcomes of interest included postoperative complications, 1-year revisions, and patient-reported outcomes. Bivariate and mixed-effects regression analyses evaluated the effect of implant type on patient outcomes. Overall, 822 patients (73.5 percent) received round and 297 patients (26.5 percent) received shaped implants. Patients undergoing unilateral reconstructions with round implants underwent more contralateral symmetry procedures, including augmentations (round, 18.7 percent; shaped, 6.8 percent; p = 0.003) and reductions (round, 32.2 percent; shaped, 20.5 percent; p = 0.019). Shaped implants were associated with higher rates of infection (shaped, 6.1 percent; round, 2.3 percent; p = 0.002), that remained significant after multivariable adjustment. Other complication rates did not differ significantly between cohorts. Round and shaped implants experienced similar 2-year patient-reported outcome scores. This prospective, multicenter study is the largest evaluating outcomes of shaped versus round implants in breast reconstruction. Although recipients of round implants demonstrated lower infection rates compared with shaped implants, these patients were more likely to undergo contralateral symmetry procedures. Both implant types yielded comparable patient-reported outcome scores. With appropriate patient selection, both shaped and round implants can provide acceptable outcomes in breast reconstruction.

    Full Text Available The development of breast implant associated anaplastic large cell lymphoma (ALCL is a rare phenomenon. A typical presentation is an effusion associated with a breast implant. Less commonly, disease can become more advanced locoregionally or distantly. The optimal treatment schema is a topic of debate: localized ALCL can potentially be cured with implant removal alone, while other cases in the literature, including those that are more advanced, have been treated with varying combinations of surgery, chemotherapy, and external beam radiotherapy. This is a case report of breast implant ALCL with pathologically proven lymph node involvement, the fifth such patient reported. Our patient experienced a favorable outcome with radiation therapy and chemotherapy.

    2014-08-01

    Full Text Available Background: Since the introduction of silicone based medical devices in to clinical practice, several reports appeared in the medical literature regarding their adverse effects. However, there are few reports of immunologic reactions to these implants.Case presentation: A case of systemic reaction to a breast implant inserted for immediate breast reconstruction in a breast cancer patient is presented. The patient developed fever and skin rash two months after the surgery. Investigations disclosed no infectious origin for the fever and a dramatic response to steroid therapy was observed.Conclusion: Immunologic reaction should be considered in case of systemic signs and symptoms after silicone breast implant placement as a rare complication.

    Full Text Available Background:. Immediate breast reconstruction is an acceptable treatment option after mastectomy for prophylaxis of early breast cancer. Different options exist for implant placement, incision technique, patient suitability, and institutional experience. This article is a case series exploring the feasibility and outcomes of patients undergoing immediate breast reconstruction using skin-sparing mastectomy without mesh or acellular dermal matrix (ADM and with a vertical inframammary incision. Methods:. A single-institution retrospective analysis was performed for all patients who underwent immediate single-stage reconstruction with subcutaneous silicon implants without ADM between 2009 and 2014 inclusive. Patient, operative and treatment variables were extracted. All patients with viable mastectomy skin flaps intraoperatively and at least 5 mm of subcutaneous tissue were eligible except for patients who were deemed too slim by the senior surgeon preoperatively and thus at risk of implant visibility or skin rippling. Results:. There were 26 patients (bilateral n = 12 and unilateral n = 14 eligible for analysis, with a median long-term follow-up of 51.5 months. The majority of complications were classified as minor affecting 46.2% of the cohort (n = 12. There were 20 episodes of complications overall. The most frequent episodes were contour defects (x = 5, minor seroma (x = 4, and malrotation and minor infection (x = 3. There was 1 episode of capsular contracture. Conclusion:. Skin-sparing mastectomy with immediate subcutaneous silicon implant reconstruction with a vertical incision and without the need for mesh or ADM is an acceptable and safe treatment option. Accurate patient selection and skin flap viability is the key to achieving optimal outcomes with this approach.

    Acceptable short-term survival rates (>90 %) of mini-implants (diameter implants as strategic abutments for a better retention of partial removable dental prosthesis (PRDP) are not available. The purpose of this study is to test the hypothesis that immediately loaded mini-implants show more bone loss and less success than strategic mini-implants with delayed loading. In this four-center (one university hospital, three dental practices in Germany), parallel-group, controlled clinical trial, which is cluster randomized on patient level, a total of 80 partially edentulous patients with unfavourable number and distribution of remaining abutment teeth in at least one jaw will receive supplementary min-implants to stabilize their PRDP. The mini-implant are either immediately loaded after implant placement (test group) or delayed after four months (control group). Follow-up of the patients will be performed for 36 months. The primary outcome is the radiographic bone level changes at implants. The secondary outcome is the implant success as a composite variable. Tertiary outcomes include clinical, subjective (quality of life, satisfaction, chewing ability) and dental or technical complications. Strategic implants under an existing PRDP are only documented for standard-diameter implants. Mini-implants could be a minimal invasive and low cost solution for this treatment modality. The trial is registered at Deutsches Register Klinischer Studien (German register of clinical trials) under DRKS-ID: DRKS00007589 ( www.germanctr.de ) on January 13(th), 2015.

    To conduct a systematic review of the literature to assess outcomes data on complications associated with implant-based breast reconstruction performed before or after chest wall radiation to assist in guiding the decision-making process for reconstruction of the irradiated breast. Studies from a PubMed search that met predetermined inclusion criteria were identified and included. Complications of interest were low- and high-grade capsular contractures, minor and major complications, reconstruction failure rates, and reconstruction completion rates. Pooled complication rates were calculated. A total of 26 articles were included in the study after screening 1,006 publications, with 14 studies presenting data on prereconstruction radiation and 23 studies presenting data on postreconstruction radiation. Complication rates evaluated in patients exposed to radiation before or after implant reconstruction were not significantly different. Reconstruction failure rates were similar at 19 and 20 % for pre- and postreconstruction radiation patients, respectively. Completion rates were similar at 83 and 80 % for pre- and postreconstruction radiation patients, respectively. Review of the current literature suggests similar overall success and failure rates with radiotherapy provided both before and after reconstruction. Failure rates in both groups of patients are clinically significant when considering implant reconstruction in the setting of radiation.

    Implanted silicone medical prostheses induce a dynamic sequence of histologic events in adjacent tissue resulting in the formation of a fibrotic peri-prosthetic capsule. In some cases, capsular calcification occurs, requiring surgical intervention. In this study we investigated capsules from silicone gel-filled breast prostheses to test the hypothesis that this calcification might be regulated by the small vitamin K-dependent protein, matrix Gla protein (MGP), a potent inhibitor of arterial calcification, or by Fetuin-A, a hepatocyte-derived glycoprotein also implicated as a regulator of pathologic calcification. Immunolocalization studies of explanted capsular tissue, using conformation-specific antibodies, identified the mineralization-protective γ-carboxylated MGP isomer (cMGP) within cells of uncalcified capsules, whereas the non-functional undercarboxylated isomer (uMGP) was typically absent. Both were upregulated in calcific capsules and co-localized with mineral plaque and adjacent fibers. Synovial-like metaplasia was present in one uncalcified capsule in which MGP species were differentially localized within the pseudosynovium. Fetuin-A was localized to cells within uncalcified capsules and to mineral deposits within calcific capsules. The osteoinductive cytokine bone morphogenic protein-2 localized to collagen fibers in uncalcified capsules. These findings demonstrate that MGP, in its vitamin K-activated conformer, may represent a pharmacological target to sustain the health of the peri-prosthetic tissue which encapsulates silicone breast implants as well as other implanted silicone medical devices.

    Patients undergoing implant-based reconstruction in the setting of postmastectomy radiation therapy suffer from increased complications and inferior outcomes compared with those not irradiated, but advances in radiation delivery have allowed for more nuanced therapy. The authors investigated whether these advances impact patient outcomes in implant-based breast reconstruction. Retrospective chart review identified all implant-based reconstructions performed at a single institution from November of 2010 to November of 2013. These data were cross-referenced with a registry of patients undergoing breast irradiation. Patient demographics, treatment characteristics, and outcomes were analyzed. Three hundred twenty-six patients (533 reconstructions) were not irradiated, whereas 83 patients (125 reconstructions) received radiation therapy; mean follow-up was 24.7 months versus 26.0 months (p = 0.49). Overall complication rates were higher in the irradiated group (35.2 percent versus 14.4 percent; p heart and lung dosing, to optimize reconstructive outcomes. Prone positioning significantly decreases the maximum skin dose and trends toward significance in reducing reconstructive complications. With continued study, this may become clinically important. Interdepartmental studies such as this one ensure quality of care. Therapeutic, III.

    (1998-2008 by the same surgeon. We analyzed factors like type of mastectomy, age, time of the reconstruction (immediate or delayed, etiology, tissue expander and implant used complications and patients´ satisfaction. All the patients except one underwent breast reconstruction in two stages, first submuscular tissue expander, and second reconstruction replacement of tissue expander with implant. A total of 24 breast were reconstructed in 19 patients using tissue expander/implant in a 10 years period, 14 unilateral and 5 bilateral. In terms of complications, they were present n 16,6 % cases. The follow up period was between 2 and 10 years. There was only 1 patient with previous quadrantectomy who received radiotherapy (4,1 %. In our opinion, breast reconstruction with tissue expander/implant remains a safe and reliable method with minimal complications and without morbidity at the donor site.

    Full Text Available Breast cancer is the leading cause of cancer death in women worldwide. Its surgical approach has become less and less mutilating in the last decades. However, the overall number of breast reconstructions has significantly increased lately. Nowadays breast reconstruction should be individualized at its best, first of all taking into consideration oncological aspects of the tumor, neo-/adjuvant treatment and genetic predisposition, but also its timing (immediate versus delayed breast reconstruction, as well as the patient’s condition and wish. This article gives an overview over the various possibilities of breast reconstruction, including implant- and expander-based reconstruction, flap-based reconstruction (vascularized autologous tissue, the combination of implant and flap, reconstruction using non-vascularized autologous fat, as well as refinement surgery after breast reconstruction.

    Myofibroblasts provide a force to decrease the surface area of breast implant capsules as the collagen matrix matures. 17-β-Oestradiol promotes myofibroblast differentiation and contraction. The aim of the study was to investigate the expression of oestrogen receptors α and β in capsular tissue. The study enrolled 70 women (80 capsules) who underwent expander or implant removal, following breast reconstruction. Specimens were stained with haematoxylin/eosin, Masson trichrome and immunohistochemistry and immunofluorescence stainings for alpha-smooth muscle actin (α-SMA), oestrogen receptor-alpha (ER-α) and oestrogen receptor-beta (ER-β). The relationship between anti-oestrogenic therapy and capsular severity was evaluated. A retrospective analysis of 233 cases of breast reconstruction was conducted. Myofibroblasts expressed ER-α, ER-β or both. In the whole sample, α-SMA score positively correlated with ER-α (p = 0.022) and ER-β expression (p < 0.004). ER-β expression negatively correlated with capsular thickness (p < 0.019). In capsules surrounding expanders α-SMA and ER-α, expressions negatively correlated with time from implantation (p = 0.002 and p = 0.016, respectively). The incidence of grade III-IV contracture was higher in patients who did not have anti-oestrogenic therapy (p < 0.036); retrospective analysis of 233 cases confirmed this finding (p < 0.0001). This study demonstrates the expression of oestrogen receptors in myofibroblasts of capsular tissue. A lower contracture severity was found in patients who underwent anti-oestrogenic therapy.

    Full Text Available Environmentally induced systemic sclerosis is a well-recognized condition, which is correlated with exposure to various chemical compounds or drugs. However, development of scleroderma-like disease after exposure to silicone has always been a controversial issue and, over time, it has triggered spirited debate whether there is a certain association or not. Herein, we report the case of a 35-year-old female who developed Raynaud’s phenomenon and, finally, systemic sclerosis shortly after silicone breast implantation surgery.

    This study reports the rate of breast reconstruction failure and cosmetic outcomes after postmastectomy radiation therapy (PMRT) with temporary tissue expanders (TEs) or implants in place. Ninety-four patients underwent mastectomy (93 unilateral, 1 bilateral; 95 cases total) and immediate TE reconstruction followed by PMRT. Ninety TEs and 5 permanent implants were irradiated. All patients received a dose of 5400 cGy given in 180-cGy fractions to the reconstructed breast. Twenty-one patients (22%) received tangents alone and 74 patients (78%) were treated with tangents and a supraclavicular field using a monoisocentric technique. Bolus was used in 91 patients (96%). Eighty-eight patients (93%) received chemotherapy and 78 patients (82%) received endocrine therapy. With a median follow-up of 24.1 months, 19 patients (20%) experienced failure of reconstruction. The 1-, 2-, and 3-year actuarial rate of reconstruction failure was 9.7%, 19.3%, and 25.5%, respectively. Infection was the most common cause of failure. Of the 19 failures, 8 patients underwent salvage procedures with flap reconstruction. Univariate analysis was performed examining age, chemotherapy use, hormone therapy use, use of a supraclavicular field, smoking status, diabetes, hypertension, and menopausal status. No risk factors were found to be associated with reconstruction failure. In patients who did not experience reconstruction failure, good/excellent cosmesis was observed in 75% of patients. In the current series of women with a high risk of locoregional recurrence, PMRT with a TE/implant in place provides good cosmesis in the majority of women, with an acceptable risk of expander or implant loss.

    To examine the risk of cardiac conduction abnormalities or severe ventricular arrhythmias requiring implantation of a cardiac implantable electronic device (CIED), either a pacemaker or an implantable cardioverter-defibrillator, subsequent to breast cancer (BC) radiotherapy (RT). All women treated for early-stage BC in Denmark from 1982 to 2005 were identified from the Danish Breast Cancer Cooperative Group. By record linkage to the Danish Pacemaker and ICD Registry information was retrieved on CIED implants subsequent to RT. Standardized incidence ratios (SIR) of CIED implantation were estimated for women receiving RT and compared to women not receiving RT for BC. Uni- and multivariate Poisson regression models were used to estimate incidence rate ratios (IRR) among irradiated women compared to non-irradiated. Of 44,423 BC patients, 179 had a CIED implanted among 18,251 women who received RT, and 401 had a CIED in 26,172 who did not receive RT. The unadjusted IRR was 1.09 (0.91-1.30 95% CI) for CIED implants among women receiving RT compared to non-irradiated women and the IRR was 1.13 (0.93-1.38 95% CI) when adjustments were made. BC RT as practiced in Denmark in 1982-2005 did not increase the risk of CIED implants. This indicates that RT for BC does not increase the risk of severe ventricular arrhythmias or cardiac conduction abnormalities. Copyright © 2016 The Authors. Published by Elsevier B.V.

    Galactorrhea is a rare event after breast augmentation. The physiopathologic bases of galactorrhea depend on the central secretion of prolactin. These physiopathologic bases must be clearly understood for the prevention and treatment of postoperative galactorrhea. This report describes two cases of a postoperative galactorrhea after aesthetic breast augmentation with silicone implants. The clinical appearance closely resembles a postoperative sepsis without hyperthermia. Bacteriologic samples are negative. Endocrinologic examination finds a characteristic hyperprolactinemia. The evolution is favorable under dopaminergic agonists.

    The cytological examination of peri-prosthetic breast effusions allowed the diagnosis of bilateral breast-implant ALK-negative anaplastic large cell lymphoma (BI-ALCL) in the case reported. Ten years after reconstructive surgery with bilateral breast implants, a large unilateral seroma developed and was cytologically analyzed. The presence of CD30 and CD4-positive large-sized atypical lymphoid cells exhibiting horseshoe-shaped nuclei and a brisk mitotic activity rendered the diagnosis of BI-ALCL. Similar cells were seen in the peri-prosthetic fluid intraoperatively collected from the contralateral breast. Although initial histological analysis of the capsulectomy specimens showed unilateral tumor, the cytological findings prompted a more thorough tissue sampling, resulting in the diagnosis of bilateral disease. BI-ALCL usually follows an indolent clinical course; however, there are reported cases with an aggressive behavior. While the presence of bilateral disease is a putative risk factor for a bad prognosis, the small number of cases reported precludes a definitive assessment of this risk. Since most BI-ALCL present with late seromas, cytologic analysis of these effusions in women with breast implants should be mandatory. Cytology is a safe tool for diagnosis and follow-up of patients with breast implant-related late seromas, sometimes proven more sensitive than histological analysis. Complete bilateral capsulectomy and a detailed histological analysis should follow a cytological diagnosis of BI-ALCL in a breast effusion in order to avoid false negative diagnoses. Our case constitutes the first published report of a bilateral BI-ALCL diagnosed by cytology. Diagn. Cytopathol. 2016;44:623-627. © 2016 Wiley Periodicals, Inc.

    To evaluate the benefits and limitations of helical tomotherapy (HT) for loco-regional irradiation of patients after a mastectomy and immediate implant-based reconstruction. Ten breast cancer patients with retropectoral implants were randomly selected for this comparative study. Planning target volumes (PTVs) 1 (the volume between the skin and the implant, plus margin) and 2 (supraclavicular, infraclavicular, and internal mammary nodes, plus margin) were 50 Gy in 25 fractions using a standard technique and HT. The extracted dosimetric data were compared using a 2-tailed Wilcoxon matched-pair signed-rank test. Doses for PTV1 and PTV2 were significantly higher with HT (V95 of 98.91 and 97.91%, respectively) compared with the standard technique (77.46 and 72.91%, respectively). Similarly, the indexes of homogeneity were significantly greater with HT (p = 0.002). HT reduced ipsilateral lung volume that received {>=}20 Gy (16.7 vs. 35%), and bilateral lungs (p = 0.01) and neighboring organs received doses that remained well below tolerance levels. The heart volume, which received 25 Gy, was negligible with both techniques. HT can achieve full target coverage while decreasing high doses to the heart and ipsilateral lung. However, the low doses to normal tissue volumes need to be reduced in future studies.

    Introduction. Medical tourism for aesthetic surgery is popular. Nontuberculous mycobacteria (NTM) occasionally cause surgical-site infections. As NTM grow in biofilms, implantations of foreign bodies are at risk. Due to late manifestation, infections occur when patients are back home, where they must be managed properly. Case Report. A 39-year-old healthy female was referred for acute infection of the right gluteal area. Five months before, she had breast implants replacement, abdominal liposuction, and gluteal lipofilling in Mexico. Three months postoperatively, implants were removed for NTM-infection in Switzerland. Adequate antibiotic treatment was stopped after seven days for drug-related hepatitis. At entrance, gluteal puncture for bacterial analysis was performed. MRI showed large subcutaneous collection. Debridement under general anaesthesia was followed by open wound management. Total antibiotic treatment was 20 weeks. Methods. Bacterial analysis of periprosthetic and gluteal liquids included Gram-stain plus acid-fast stain, and aerobic, anaerobic and mycobacterial cultures.  Results. In periprosthetic fluid, Mycobacterium abscessus, Propionibacterium, and Staphylococcus epidermidis were identified. The same M. abscessus strain was found gluteally. The gluteal wound healed within six weeks. At ten months' follow-up, gluteal asymmetry persists for deep scarring. Conclusion. This case presents major complications of multisite aesthetic surgery. Surgical-site infections in context of medical tourism need appropriate bacteriological investigations, considering potential NTM-infections.

    The major focus of research when addressing nipple reconstruction has been on developing new techniques to provide for long-lasting nipple projection. Rarely, has the outcome of nipple reconstruction as it relates to postoperative morbidity, particularly after implant-based breast reconstruction, been analyzed. A "matched-pair" study was designed to specifically answer the question whether a history of radiotherapy predisposes to a higher complication rate after nipple reconstruction in patients after implant-based breast reconstruction. Only patients with a history of unilateral radiotherapy who underwent bilateral mastectomy and implant-based breast reconstruction followed by bilateral nipple reconstruction were included in the study. A total of 17 patients (i.e. 34 nipple reconstructions) were identified who met inclusion criteria. The mean age of the study population was 43.5 years (range, 23-69). Complications were seen after a total of 8 nipple reconstructions (23.5 percent). Of these, 7 complications were seen on the irradiated side (41.2 percent) (p = 0.03). While nipple reconstruction is a safe procedure after implant-based breast reconstruction in patients without a history of radiotherapy the presence of an irradiated field converts it to a procedure with a significant increase in postoperative complication rate.

    Full Text Available Background: Breast cancer is the most frequent malignant tumor in women worldwide. In recent years, defined reconstruction principles along with numerous surgical techniques with volume replacement have been published. Autologous breast reconstruction is more natural but leaves donor site morbidity. It provides the opportunity to restore the breast mound without the need for scars. This study aims to evaluate the complications of radiotherapy after immediate breast reconstruction with implants in breast cancer patients who submitted to skin sparing mastectomy and nipple sparing mastectomy by taking into consideration the risk factors and management at our institution. Methods: The current study prospectively included patients with invasive breast cancer admitted between January and June 2012 who were scheduled for skin sparing mastectomy or nipple sparing mastectomy and axillary dissection followed by immediate breast reconstruction with implant. Patients received adjuvant chemotherapy followed by conventional fractionated radiation. Complications were classified as either minor or major. The minor complications included capsular contracture (Baker 1-2, seroma, minor skin infection and skin dehiscence without exposure of the implant. Major complications included capsular contracture (Baker 3-4, severe infection and major wound dehiscence with implant exposure. Capsular contracture was scored according to the modified Baker classification. Results: The study included 38 patients. Of these, 28 had skin sparing mastectomy while 10 underwent nipple sparing mastectomy. The overall complication rate was 71%. We observed minor complications in 18 patients while 9 patients had major complications. Complications occurred with a median time of 13 months following radiotherapy completion. All minor complications were managed conservatively whereas all major complications required repeat surgery. No loco-regional recurrences occurred during the follow up

    Full Text Available Background. In March 2010, ANSM (Agence Nationale de Sécurité du Medicament, the French Medical Regulatory Authority, withdrew Poly Implant Prothèse (PIP breast implants from the market due to the use of non-medical-grade silicone gel. The aim of this study was to compare the removal rate (and reasons thereof of breast implants produced by different manufacturers before the ANSM alert. Materials and Methods. From October 2006 to January 2010, 652 women received 944 implants after breast cancer surgery at the Gustave Roussy Comprehensive Cancer Center, Paris (France. The complications and removal rates of the different implant brands used (PIP, Allergan, and Pérouse were evaluated and compared. Results. PIP implants represented 50.6% of the used implants, Allergan 33.4%, and Pérouse 16%. The main reasons for implant removal were patient dissatisfaction due to aesthetic problems (43.2%, infection (22.2%, and capsular contracture (13.6%. Two years after implantation, 82% of Pérouse implants, 79% of PIP, and 79% of Allergan were still in situ. There was no difference in removal rate among implant brands. Conclusion. Before the ANSM alert concerning the higher rupture rate of PIP breast implants, our implant removal rate did not predict PIP implant failure related to the use of nonapproved silicone gel.

    The recall of Poly Implant Prothese (PIP) silicone breast implants in 2010 resulted in large numbers of asymptomatic women with implants who underwent magnetic resonance imaging (MRI) screening. This study's aim was to assess the accuracy and interobserver variability of MRI screening in the detection of rupture and extracapsular silicone leakage. A prospective study included 107 women with 214 PIP implants who underwent explantation preceded by MRI. In 2013, two radiologists blinded for previous MRI findings or outcome at surgery, independently re-evaluated all MRI examinations. A structured protocol described the MRI findings. The ex vivo findings served as reference standard. In 208 of the 214 explanted prostheses, radiologists agreed independently about the condition of the implants. In five of the six cases they disagreed (2.6 %), but subsequently reached consensus. A sensitivity of 93 %, specificity of 93 %, positive predictive value of 77 % and negative predictive value of 98 % was found. The interobserver agreement was excellent (kappa value of 0.92). MRI has a high accuracy in diagnosing rupture in silicone breast implants. Considering the high kappa value of interobserver agreement, MRI appears to be a consistent diagnostic test. A simple, uniform classification, may improve communication between radiologist and plastic surgeon. (orig.)

    Full Text Available Abstract Background Phyllodes tumors are uncommon tumors of the breast that exhibit aggressive growth. While surgical management of the tumor has been reported, a single surgical approach with immediate breast reconstruction using AlloDerm has not been reported. Case presentation A 22-year-old woman presented with a 4 cm mass in the left breast upon initial examination. Although the initial needle biopsy report indicated a fibroadenoma, the final pathologic report revealed a 6.5 cm × 6.4 cm × 6.4 cm benign phyllodes tumor ex vivo. Treatment was a simple nipple-sparing mastectomy coupled with immediate breast reconstruction. After the mastectomy, a subpectoral pocket was created for a saline implant and AlloDerm was stitched to the pectoralis and serratus muscle in the lower-pole of the breast. Conclusions Saline implant with AlloDerm can be used for immediate breast reconstruction post-mastectomy for treatment of a phyllodes tumor.

    Background A large number of clinical studies have reported that the different materials used in breast implants were a possible cause of the different incidence rates of capsular contracture observed in patients after implantation. However, this theory lacks comprehensive support from evidence-based medicine, and considerable controversy remains. Objectives In this study, a cumulative systematic review examined breast augmentation that used implants with textured or smooth surfaces to analyze the effects of these two types of implants on the occurrence of postoperative capsular contracture. Methods We conducted a comprehensive search of literature databases, including PubMed and EMBASE, for clinical reports on the incidence of capsular contracture after the implantation of breast prostheses. We performed a cumulative meta-analysis on the incidence of capsular contracture in order from small to large sample sizes and conducted subgroup analyses according to the prosthetic material used, the implant pocket placement, the incision type and the duration of follow-up. Relative risks (RR) and 95% confidence intervals (CI) were used as the final pooled statistics. Results This meta-analysis included 16 randomized controlled trials (RCTs) and two retrospective studies. The cumulative comparison of textured and smooth breast implants showed statistical significance at 2.13 (95% CI, 1.18-3.86) when the fourth study was entered into the analysis. With the inclusion of more reports, the final results indicated that smooth breast implants were more likely to be associated with capsular contracture, with statistical significance at 3.10 (95% CI, 2.23-4.33). In the subgroup analyses, the subgroups based on implant materials included the silicone implant group and the saline implant group, with significant pooled statistical levels of 4.05 (95% CI, 1.97-8.31) and 3.12 (95% CI, 2.19-4.42), respectively. According to implant pocket placement, a subglandular group and a submuscular

    Full Text Available To compare the breast cancer-specific survival (BCSS between patients who underwent tissue or implant reconstruction after mastectomy.We used the database from Surveillance, Epidemiology, and End Results (SEER registries and compared the BCSS between patients who underwent tissue and implant reconstruction after mastectomy. Cox-regression models were fitted, adjusting for known clinicopathological features. The interaction between the reconstruction types (tissue/implant and nodal status (N-stage was investigated.A total of 6,426 patients with a median age of 50 years were included. With a median follow up of 100 months, the 10-year cumulative BCSS and non-BCSS were 85.1% and 95.4%, respectively. Patients who underwent tissue reconstruction had tumors with a higher T-stage, N-stage, and tumor grade and tended to be ER/PR-negative compared to those who received implant reconstruction. In univariate analysis, implant-reconstruction was associated with a 2.4% increase (P = 0.003 in the BCSS compared with tissue-reconstruction. After adjusting for significant risk factors of the BCSS (suggested by univariate analysis and stratifying based on the N-stage, there was only an association between the reconstruction type and the BCSS for the N2-3 patients (10-year BCSS of implant vs. tissue-reconstruction: 68.7% and 59.0%, P = 0.004. The 10-year BCSS rates of implant vs. tissue-reconstruction were 91.7% and 91.8% in N0 patients (P>0.05 and 84.5% and 84.4% in N1 patients (P>0.05, respectively.The implant (vs. tissue reconstruction after mastectomy was associated with an improved BCSS in N2-3 breast cancer patients but not in N0-1 patients. A well-designed, prospective study is needed to further confirm these findings.

    Post-mastectomy breast reconstruction with expanders and implants is recognized as an integral part of breast cancer treatment. Its main complication is represented by capsular contracture, which leads to poor expansion, breast deformation, and pain, often requiring additional surgery. In such a scenario, the debate continues as to whether the second stage of breast reconstruction should be performed before or after post-mastectomy radiation therapy, in light of potential alterations induced by irradiation to silicone biomaterial. This work provides a novel, multi-technique approach to unveil the role of radiotherapy in biomaterial alterations, with potential involvement in capsular contracture. Following irradiation, implant shells underwent mechanical, chemical, and microstructural evaluation by means of tensile testing, Attenuated Total Reflectance Fourier Transform InfraRed spectroscopy (ATR/FTIR), Scanning Electron Microscopy (SEM), high resolution stylus profilometry, and Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS). Our findings are consistent with radiation-induced modifications of silicone that, although not detectable at the microscale, can be evidenced by more sophisticated nanoscale surface analyses. In light of these results, biomaterial irradiation cannot be ruled out as one of the possible co-factors underlying capsular contracture. - Highlights: • The debate continues whether to perform breast reconstruction before or after PMRT. • Radiation therapy may alter implant material, concurring to capsular contracture. • In this work, irradiated implants were investigated by a multi-technique approach. • Radiation-induced alterations could be evidenced by ATR/FTIR and ToF-SIMS. • Reported alteration might represent a co-factor underlying capsular contracture.

    Background and purpose: Radiotherapy (RT) of reconstructed breasts was associated with major complications and poor cosmetic outcome. The present study assessed complication rates, the link between risk factors and prosthesis removal, as well as cosmetic outcomes. Patients and methods: From 1997 to 2009, 101 consecutive patients received RT after breast reconstruction because of risk factors for relapse (92) or because relapse had occurred (9). At RT, 90 patients had temporary tissue expanders and 11 had permanent implants. Twelve patients underwent neo-adjuvant chemotherapy; all patients received adjuvant chemo- and/or hormone therapy. Results: At a median follow-up of 50 months, late toxicities occurred in 28 patients: pain in 7, lymphedema in 6, G1 cutaneous toxicity in 5, and subcutaneous toxicity in 19 (2G1, 9G2, 7G3, 1G4), with more than one side effect in 12. In 8 patients the prosthesis ruptured (3), was displaced (3), was displaced and ruptured (1), or lost shape (1). Capsular contracture was classified in 89 patients as IA in 14, IB in 47, II in 10, III in 11, and IV in 7. Twelve prostheses (11.9%) were removed. The only significant factor for prosthesis removal was age (p = 0.007). Judgments of cosmetic results were available from 81 physicians and 84 patients. Outcome was excellent/good in 58/81 physician judgments and in 57/84 patient evaluations. Overall inter-rater agreement on outcome was good ({kappa}-value 0.64; 95% CI: 0.48-0.79). Conclusion: RT to reconstructed breasts was associated with low rates of late toxicity and prosthesis removal. Cosmetic outcomes were, on the whole, good to excellent. (orig.)

    Background Despite 82% of patients reporting psychosocial improvement following breast reconstruction, only 33% patients choose to undergo surgery. Implant reconstruction outnumbers autologous reconstruction in many centres. Methods A systematic review of the literature was undertaken. Inclusion required: (I) Meta-analyses or review articles; (II) adult patients aged 18 years or over undergoing alloplastic breast reconstruction; (III) studies including outcome measures; (IV) case series with more than 10 patients; (V) English language; and (VI) publication after 1st January, 2000. Results After full text review, analysis and data extraction was conducted for a total of 63 articles. Definitive reconstruction with an implant can be immediate or delayed. Older patients have similar or even lower complication rates to younger patients. Complications include capsular contracture, hematoma and infection. Obesity, smoking, large breasts, diabetes and higher grade tumors are associated with increased risk of wound problems and reconstructive failure. Silicone implant patients have higher capsular contracture rates but have higher physical and psychosocial function. There were no associations made between silicone implants and cancer or systemic disease. There were no differences in outcomes or complications between round and shaped implants. Textured implants have a lower risk of capsular contracture than smooth implants. Smooth implants are more likely to be displaced as well as having higher rates of infection. Immediate breast reconstruction (IBR) gives the best aesthetic outcome if radiotherapy is not required but has a higher rate of capsular contracture and implant failure. Delayed-immediate reconstruction patients can achieve similar aesthetic results to IBR whilst preserving the breast skin if radiotherapy is required. Delayed breast reconstruction (DBR) patients have fewer complications than IBR patients. Conclusions Implant reconstruction is a safe and popular

    Nipple-sparing mastectomy permits complete preservation of the nipple-areola complex with excellent aesthetic results and with oncologic safety similar to that associated with traditional mastectomy techniques. However, outcomes have not been directly compared for tissue expander-, immediate implant-, and autologous tissue-based breast reconstruction after nipple-sparing mastectomy. All patients undergoing nipple-sparing mastectomy from 2006 to June of 2016 were identified at a single institution. Demographics and outcomes were analyzed and compared among different types of breast reconstruction. A total of 1028 nipple-sparing mastectomies were performed. Of these, 533 (51.8 percent) were tissue expander-based, 263 (25.6 percent) were autologous tissue-based, and 232 (22.6 percent) were immediate implant-based reconstructions. Tissue expander-based reconstructions had significantly more minor cellulitis (p = 0.0002) but less complete nipple necrosis (p = 0.0126) and major mastectomy flap necrosis (p < 0.0001) compared with autologous tissue-based reconstructions. Compared to immediate implant-based reconstruction, tissue expander-based reconstructions had significantly more minor cellulitis (p = 0.0006) but less complete nipple necrosis (p = 0.0005) and major (p < 0.0001) and minor (p = 0.0028) mastectomy flap necrosis (p = 0.0059). Immediate implant-based reconstructions had significantly more minor cellulitis (p = 0.0051), minor mastectomy flap necrosis (p = 0.0425), and partial nipple necrosis (p = 0.0437) compared with autologous tissue-based reconstructions. Outcomes were otherwise equivalent among the three groups. Tissue expander, immediate implant, and autologous tissue breast reconstruction techniques may all be safely offered with nipple-sparing mastectomy. However, reconstructive complications appear to be greater with immediate implant- and autologous tissue-based techniques compared with tissue expander-based reconstruction. Therapeutic, III.

    In Mexico, breast cancer is the leading cancer-related death among women and most cases are diagnosed at advanced stages (50-60%). We hypothesized health system factors could be partly responsible for this delay and performed a prospective review of 166 new breast cases at a major public hospital in Mexico City. Our analysis confirmed the prevalence of locally advanced and metastatic disease (47% of patients). A subset analysis of 32 women with confirmed stage I-IIIC breast cancer found an average time interval of 1.8 months from symptom onset to first primary care consultation (PCC), with an additional 6.6 months from first PCC to confirmed diagnosis, and 0.6 months from diagnosis to treatment initiation. Patients underwent an average of 7.9 clinic visits before confirmed diagnosis. Findings suggest that protracted referral time from primary to specialty care accounts for the bulk of delay, with earlier stage patients experiencing longer delays. These findings reveal a critical need for further study and exploration of interventions.

    The case of a giant thoracic desmoid tumour in a 44-year-old woman, who presented two years following a breast reconstruction with a latissimus dorsi (LD) flap and implant, is reported. Clinical findings included a rapidly growing, painless mass. Computed tomography (CT) suggested skin and intercostal soft tissue invasion. The tumour was resected en bloc with the LD muscle, implant capsule and underlying rib segments. The resultant thoracic and abdominal wall defects were reconstructed with Dualmesh® and polypropylene meshes respectively. There was no evidence of recurrence at thirty-six months follow-up.

    An increased risk of delayed cardiac perforation (DCP) with active-fixation small-diameter ICD leads has recently been reported, especially with regard to the St. Jude Riata lead (St. Jude Medical, Sylmar, CA, USA). Few data on the risk of DCP in small versus standard-diameter leads implanted in a single high-volume center are available. Moreover, no data on the performances of St. Jude's new small-diameter Durata lead are as yet available. The aim of this study was to assess the incidence of DCP in small versus standard-diameter leads implanted in our center. Between January 2003 and October 2009, 437 small-diameter leads (190 Medtronic Sprint Fidelis [Medtronic Inc., Minneapolis, MN, USA], 196 Riata, 51 Durata) and 421 standard-diameter (>8 Fr) leads were implanted. After a median follow-up of 421 days seven of 858 (0.8%) patients experienced DCP. The incidence of DCP was higher in patients with small-diameter leads than in those with standard-diameter leads (1.6% vs 0%, P = 0.01). No cases of DCP occurred among 371 passive-fixation leads versus 1.4% of events among active-fixation leads (P = 0.02). The incidence of DCP was 2.5% in Riata, 1% in Sprint Fidelis, 0% in Durata, and 0% in standard-diameter leads (P < 0.01 for Riata vs standard-diameter leads). Small-diameter active-fixation ICD leads are at increased risk of DCP, a finding mostly due to the higher incidence of events in the Riata family. By contrast, passive-fixation small-diameter leads and standard-diameter leads appear to be safe enough regarding the risk of DCP. Our preliminary data suggest that the new Durata lead is not associated with an increased risk of DCP. ©2010, The Authors. Journal compilation ©2010 Wiley Periodicals, Inc.

    In response to a Hazard Notice by the Medical Devices Agency of the UK in 2000 regarding the Trilucent breast implant (TBI), an expert panel was convened to implement a research program to determine whether genotoxic compounds were formed in the soybean oil filler (SOF) of TBIs and whether these could be released to produce local or systemic genotoxicity. The panel established a research program involving six laboratories. The program recruited 47 patients who had received TBIs (9 patients had received silicone implants previously). A reference group (REBI) of 34 patients who had exchanged either silicone (17 patients) implants (REBI-E) or patients (17) who were to receive primary implantation augmentation with silicone (REBI-PIA), and who were included as needed to increase either the pre- or post-explantation sample number. Of the 17 REBI-E patients, 5 had silicone implants and 12 had saline implants previously (prior to the last exchange). Investigation was undertaken before and after replacement surgery in the TBI patients and before and after replacement or augmentation surgery in the REBI patients. The pre- to post-operative sample interval was 8-12 weeks. Pre-operative samples were collected within 7 days prior to the operation. Information on a variety of demographic and behavioral features was collected. Biochemical and biological endpoints relating to genotoxic lipid peroxidation (LPO) products potentially formed in the SOF, and released locally or distributed systemically, were measured. The SOF of explanted TBIs was found to have substantial levels of LPO products, particularly malondialdehyde (MDA), and low levels of trans-4-hydroxy-2-nonenal (HNE) not found in unused implants. Mutagenicity of the SOF was related to the levels of MDA. Capsules that formed around TBIs were microscopically similar to those of reference implants, but MDA-DNA adducts were observed in capsular macrophages and fibroblasts of only TBI capsules. These cell types are not

    Full Text Available Background. In Haiti, breast cancer patients present at such advanced stages that even modern therapies offer modest survival benefit. Identifying the personal, sociocultural, and economic barriers-to-care delaying patient presentation is crucial to controlling disease. Methods. Patients presenting to the Hôpital Bon Sauveur in Cange were prospectively accrued. Delay was defined as 12 weeks or longer from initial sign/symptom discovery to presentation, as durations greater than this cutoff correlate with reduced survival. A matched case-control analysis with multivariate logistic regression was used to identify factors predicting delay. Results. Of N=123 patients accrued, 90 (73% reported symptom-presentation duration and formed the basis of this study: 52 patients presented within 12 weeks of symptoms, while 38 patients waited longer than 12 weeks. On logistic regression, lower education status (OR = 5.6, P=0.03, failure to initially recognize mass as important (OR = 13.0, P<0.01, and fear of treatment cost (OR = 8.3, P=0.03 were shown to independently predict delayed patient presentation. Conclusion. To reduce stage at presentation, future interventions must educate patients on the recognition of initial breast cancer signs and symptoms and address cost concerns by providing care free of charge and/or advertising that existing care is already free.

    TiLOOP(®) Bra is a permanent titanium-coated polypropylene mesh currently used in post-mastectomy breast reconstruction with implants. This mesh is generally presented as inducing low-grade inflammatory reactions, but only few reports focused on its possible side effects. In the case described here, the use of the mesh led to minor clinical problems that needed to be clinically and surgically managed at the same time as a local relapse. A patient with high-grade ductal carcinoma in situ underwent primary surgery (nipple-sparing mastectomy and one-stage reconstruction using the TiLOOP(®) Bra mesh) and was subsequently referred for radiological and clinical investigation when various nodules became apparent during a follow-up physical examination. Prior to the histopathological proof, the diagnosis of local recurrence was complicated by the occurrence of an extensive granulomatous reaction in the fixation areas along with mild inflammatory changes scattered on the surface of the mesh. This case illustrates a side effect of titanium-coated permanent mesh in immediate implant-based reconstruction, i.e. the formation of granulomas in the inframammary fold, probably in the area where the mesh had been folded or fixed. We propose a safer technical approach to avoid the problem and a clinical management strategy for patients at high risk of local recurrence who develop granuloma-like nodules. A surgical technique is suggested to prevent granuloma formation. If, however, subcutaneous nodules that may be local recurrences do appear, they should not be interpreted by default as a granulomatous reaction, but should be fully investigated and possibly excised.

    The replacement of medical-grade silicone with industrial-grade silicone material in some silicone gel-filled breast implants (SBI) manufactured by Poly Implant Prothèse and Rofil Medical Nederland B.V., reported in 2010, which resulted in a higher rupture tendency of these SBI, demonstrates the need for non-invasive, sensitive monitoring and screening methods. Therefore a sensitive method based on large volume injection-gas chromatography coupled to mass spectrometry (LVI-GC/MS) was developed to determine octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcyclo-hexasiloxane (D6) in blood samples from women with intact (n = 13) and ruptured SBI (n = 11). With dichloromethane extraction, sample cooling during preparation, and analysis extraction efficiencies up to 100 % and limits of detection of 0.03-0.05 ng D4-D6/g blood were achieved. Blood samples from women with SBI were investigated. In contrast to women with intact SBI, in blood from women with ruptured SBI higher D4 and D6 concentrations up to 0.57 ng D4/g blood and 0.16 ng D6/g blood were detected. With concentrations above 0.18 D4 ng/blood and 0.10 ng D6/g blood as significant criteria for ruptured SBI, this developed analytical preoperative diagnostic method shows a significant increase of the recognition rate. Finally a higher precision (error rate 17%) than the commonly used clinical diagnostic method, mamma sonography (error rate 46%), was achieved.

    Mycobacterial infection is a rare complication associated with breast surgery using implants. Over the course of 5 months, one center experienced 12 such cases, 10 of which were linked to a single surgeon. Most presented 3 to 6 weeks postoperatively with clear serous drainage from the incision, minimal local redness, no fever or other systemic signs of infection, and negative standard bacterial cultures. Patients were given empiric broad-spectrum oral antibiotic therapy. In eight cases, implants were removed and exchanged for new devices after irrigation of the pocket with antibiotics; these patients nonetheless experienced recurrent infection, which led to explantation (without immediate exchange for new implants). The last two patients proceeded straight to explantation. Because mycobacteria grow in water, the water supply and air-conditioning system were initially suspected as the source, and both were disinfected. However, this did not stop the outbreak. Eventually, the source was traced to a new species of mycobacteria isolated from a garden hot tub. These bacteria had then been unwittingly transferred to patients during surgery. A Triclosan-containing shampoo effectively ended the outbreak. This series is unique in several respects: the novelty of the pathogen, the heavy colonization of the surgeon, and the mechanism of transmission (the first occurrence of human-to-human mycobacterial transfer published in the plastic surgery literature). Surgeons who perform breast surgery with implants should be aware of the possibility of mycobacterial infection. Proactive culturing of the organism, use of antibiotics, and reoperation are essential to good outcomes.

    Our aim was to evaluate the influence of preservation of the alveolar ridge on delayed implants with different defects in the buccal bone. We enrolled 60 patients who had one posterior mandibular tooth extracted. Cone-beam computed tomography (CT) was used to measure the buccal bone defects in the alveolar ridge before the tooth was extracted (level A=3 to 5 mm, and level B=more than 5 mm). After the tooth had been extracted, the socket either had the alveolar ridge preserved (trial group) or it was left to heal spontaneously (control group). The changes in the dimensions of the alveolar ridge from preoperatively to 6 months postoperatively were evaluated by cone-beam CT. Suitable implants were inserted 6 months later, and their length and diameter recorded. The implant stability quotient was evaluated for the following 3 months. The dimensions of the bone in the alveolar ridge in the trial group were significantly less than those in the control groups in both levels. Fifty-seven patients required implants (except 3 in level B in the control group). There were more longer and wider implants in the trial group than in the control group in Level B. 3 months after implantation, there were no significant differences in implant stability quotients between the groups, though in the control group, Level B, the mean (SD) value was 69.50 (1.00) while in the other groups values were all above 70 at 3 months. We conclude that when the defect in the buccal bone was more than 5mm, the alveolar ridge preservation demonstrated a remarkable effect in preserving the alveolar ridge dimension and delayed implantation.

    Full Text Available OBJECTIVE: Characterize diagnosis and treatment of breast cancer in Bogota, Colombia and examine the extent and determinants of patient delay. MATERIAL AND METHODS: Using a census approach we identified 1 106 women with breast cancer. Information was gathered through personal interviews and the review of medical records. Patient delay was defined as the time elapsed from first symptoms to initial consultation. RESULTS: More than 80% of the women (902 consulted due to symptoms; the majority had advanced-stage disease. Patient delay was established in 20.3% and the main related factors were older age, lack of social security and advanced clinical stage. Higher education in patients was associated with reduced delays. DISCUSSION: Women do not recognize breast cancer symptoms. Patient delay and related factors are similar to those found in other studies. There is an urgent need to develop communication and education strategies regarding breast cancer symptoms and early detection.OBJETIVO: Caracterizar el diagnóstico y tratamiento de mujeres con cáncer de mama en Bogotá, Colombia; establecer la demora de pacientes en la asistencia a consulta y los factores relacionados.

    Prosthesis-based techniques are the predominant form of breast reconstruction worldwide, with two-stage tissue expander procedures being the most popular. In the past decade, there has been increasing interest in performing single-stage implant reconstruction immediately following mastectomy as an attempt to simplify the reconstructive course and improve psychosocial morbidity. However, there is a paucity of large-scale, multi-institutional data comparing the outcomes of these two reconstructive strategies. Patients who underwent immediate tissue expander or implant reconstruction following mastectomy from 2006-2010 were identified using standardised operation codes. Demographic information for patients, 30-day outcomes, and adverse events for each type of reconstruction were analysed and compared between groups. A total of 10,561 patients underwent immediate breast reconstruction. There were 9033 patients who underwent tissue expander placement (2752 bilateral), and 1528 patients who underwent immediate implant placement (485 bilateral). Patients who had implant placement demonstrated increased rates of overall complications (6.8% compared with 5.4%, p = 0.02) and prosthesis failure (1.4% compared with 0.8%, p = 0.04). There was no difference in the rate of any surgical site infections (3.9% compared with 3.4%, p = 0.39), reoperation (7.5% compared with 6.9%, p = 0.40), or major medical complications (1.8% compared with 1.6%, p = 0.57). Both immediate one-stage, direct-to-implant, and two-stage tissue expander reconstructions result in low rates of morbidity. One-stage reconstruction suggests a slightly higher complication rate related to prosthesis failure.

    During the U.S. Food and Drug Administration's advisory panel hearings to evaluate the premarket approval for conventional silicone gel implants on October 14 and 15, 2003, panel members and patient advocate representatives focused on four specific areas of concern: reoperation rates in primary breast augmentation; levels, depth, and methods of patient education and informed consent; modes, frequency, and management of silicone gel implant device failures, including management of "silent" ruptures; and methods of monitoring and managing symptoms or symptom complexes that may or may not be associated with connective tissue disease or other undefined symptom complexes. These concerns, with a reported 20 percent reoperation rate for primary augmentation within just 3 years, and a lack of concise, definitive management protocols addressing these areas of concern may have contributed to the Food and Drug Administration's rejection of the premarket approval, despite the panel's recommendation for approval. This article presents decision and management algorithms that have been used successfully for 7 years in a busy breast augmentation practice (Tebbetts and Tebbetts). The algorithms have been further expanded and refined by a group of surgeons with diverse experiences and expertise to address the following clinical situations that coincide with concerns expressed by patients and the Food and Drug Administration: implant size exchange, grade III to IV capsular contracture, infection, stretch deformities (implant bottoming or displacement), silent rupture of gel implants, and undefined symptom complexes (connective tissue disease or other). In one practice (Tebbetts and Tebbetts) that uses the TEPID system (tissue characteristics of the envelope, parenchyma, and implant and the dimensions and fill distribution dynamics of the implant), implant selection is based on quantified patient tissue characteristics, pocket selection is based on quantified soft-tissue coverage, and

    In this study we performed 77 procedures on 65 patients fulfilling the oncological criteria for skin-sparing mastectomy and presenting with large or medium size breasts. All the operations were performed as a single-stage procedure with an anatomical prosthesis allocated into a compound pouch, made up of the pectoralis major, serratus anterior fascia, and a lower dermal adipose flap. The medium size of the anatomical implants employed was 444.3 cc. The implant removal rate was 14.2%. At a median follow-up of 36 months we reported a 0.5% local recurrence rate per year. The overall specific survival rate was 98.2%. This study confirms the safety and effectiveness of this technical variation of skin and nipple-sparing mastectomies. All breast, irrespective of mammary shape and size, can be reconstructed with medium size implants and, if required, contralateral adjustments. The overall complication rate is in keeping with previous studies. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Staphylococcus epidermidis and Staphylococcus aureus are currently considered two of the most important pathogens in nosocomial infections associated with catheters and other medical implants and are also the main contaminants of medical instruments. However because these species of Staphylococcus are part of the normal bacterial flora of human skin and mucosal surfaces, it is difficult to discern when a microbial isolate is the cause of infection or is detected on samples as a consequence of contamination. Rapid identification of invasive strains of Staphylococcus infections is crucial for correctly diagnosing and treating infections. The aim of the present study was to identify specific genes to distinguish between invasive and contaminating S. epidermidis and S. aureus strains isolated on medical devices; the majority of our samples were collected from breast prostheses. As a first step, we compared the adhesion ability of these samples with their efficacy in forming biofilms; second, we explored whether it is possible to determine if isolated pathogens were more virulent compared with international controls. In addition, this work may provide additional information on these pathogens, which are traditionally considered harmful bacteria in humans, and may increase our knowledge of virulence factors for these types of infections.

    Conclusions: Preoperative signs can be predictive of PIP implant failure. Brown-stained implants are more prone to rupture. The presence of iodine in the gel suggests unacceptable permeability of the shell early in the implant’s life span. A noninvasive screening test to detect brown implants in situ could help identify implants at risk of failure in those who elect to keep their implants.

    A major complication of silicone breast implants is the formation of a capsule around the implant known as capsular contracture which results in the distortion of the implant. Recently, a mouse model for studying capsular contracture was examined using micro-computed tomography (micro-CT), however, only qualitative changes were reported. The aim of this study was to develop a quantitative method for comparing the shape changes of silicone implants using in vivo micro-CT. Mice were bilaterally implanted with silicone implants and underwent ionizing radiation to induce capsular contracture. On day 28 post-surgery mice were examined in vivo using micro-CT. The reconstructed cross-section images were visually inspected to identify distortion. Measurements were taken in 2D and 3D to quantify the shape of the implants in the normal (n = 11) and distorted (n = 5) groups. The degree of anisotropy was significantly higher in the distorted implants in the transaxial view (0.99 vs. 1.19, p = 0.002) and the y-axis lengths were significantly shorter in the sagittal (9.27 mm vs. 8.55 mm, p = 0.015) and coronal (9.24 mm vs. 8.76 mm, p = 0.031) views, indicating a deviation from the circular cross-section and shortening of the long axis. The 3D analysis revealed a significantly lower average thickness (sphere-fitting method) in distorted implants (6.86 mm vs. 5.49 mm, p = 0.002), whereas the volume and surface area did not show significant changes. Statistically significant differences between normal and distorted implants were found in 2D and 3D using distance measurements performed via micro-CT. This objective analysis method can be useful for a range of studies involving deformable implants using in vivo micro-CT. © 2016 Wiley Periodicals, Inc.

    In 1977 we reported our results of an ongoing randomized clinical trial evaluating early or delayed adjuvant chemotherapy utilizing 5-flourouracil, cytoxan and prednisone in premenopausal patients with recurrent or advanced breast cancer. At that time the group receiving early systemic chemotherapy was shown to have an improved progression-free interval and appeared to have a trend toward improved survival. The results of subsequent analysis after over 4 more years of follow-up indicate however, that while early employment of systemic chemotherapy does indeed prolong the progression-free interval, and while this advantage has been maintained, there is no survival advantage shown for either group of patients.

  12. A TRAM flap design refinement for use in delayed breast reconstruction.

    Autologous breast reconstruction following mastectomy is commonly achieved using the free Transverse Rectus Abdominis Myocutaneous (TRAM) flap. Since its first description, refinements and modifications have resulted in improved operative techniques and more aesthetically pleasing reconstructions. Pre-operative flap design, however, is a relatively new concept that has not received much attention in the literature. Patients who undergo breast reconstruction may have large, ptotic contralateral breasts. In these patients there is a tendency to raise a large abdominal flap in an attempt to achieve symmetry, or simply a larger breast. This has the potential to lead to tight closure of the abdomen and the risk of subsequent wound problems. Reconstructions that are too small or have inadequate ptosis commit the patient to contralateral breast surgery to achieve symmetry. Pre-operatively designing the flap, using a template created from the opposite breast, can help achieve a good match, often reducing the need for contralateral breast surgery. Even when contralateral breast reduction surgery is planned in advance, many of these patients still require, and prefer, a large reconstruction in order to achieve a well-proportioned result. We present a design template that addresses these particular issues and in the senior author\\'s hands has proved to be a very effective technique. Our technique allows raising an abdominal flap of less vertical height than traditionally used (thus reducing the risk of tight abdominal closure) and incorporates an inverted V-shaped flap of skin from the inferior mastectomy skin flap into the reconstruction. This allows more flap tissue to be available to fill the upper poles of the reconstructed breast and at the same time produces good ptosis.

    Use of acellular dermal matrix in breast reconstruction has been associated with increased complications. However, existing studies are generally small, from single centers, and underpowered to control for confounding using regression techniques. Here, the Tracking Outcomes and Operations in Plastic Surgery database was used to examine the effect of acellular dermal matrix on expander/implant loss when controlling for other confounders. Analysis was limited to patients having tissue expander or implant-based breast reconstruction. Surgeon-reported data, International Classification of Diseases, Ninth Edition codes, and Current Procedural Terminology codes were used to identify independent variables. The dependent variable of interest was 30-day rates of tissue expander or implant loss. Bivariate statistics were performed. Multivariable logistic regression identified independent predictors of expander/implant loss when controlling for other confounders. Data were available for 14,249 patients. The overall rate of expander/implant loss was 2.05 percent. Bivariate analysis demonstrated acellular dermal matrix was associated with an absolute increase in expander/implant loss of 0.7 percent (1.88 percent versus 2.58 percent, p = 0.012). The regression model demonstrated that rising body mass index, current smoking, and presence of diabetes were each independent predictors of expander/implant loss. When controlling for all other identified confounders, use of acellular dermal matrix was associated with a significant increase in expander/implant loss (odds ratio, 1.42; 95 percent confidence interval, 1.04 to 1.94; p = 0.026). Thirty-day risk for expander/implant loss after tissue expander or implant-based breast reconstruction was 2.05 percent. Use of acellular dermal matrix was associated with a 0.7 percent absolute risk increase for expander/implant loss. Risk, III.

    The purpose of this study was to characterize the recurrence dynamics in breast cancer patients after delayed reconstruction. We hypothesized that surgical reconstruction might stimulate dormant micrometastases and reduce time to recurrence. All mastectomy breast cancer patients with delayed surgical reconstruction at Haukeland University Hospital, between 1977 and 2007, n = 312, were studied. Our control group consisted of 1341 breast cancer patients without reconstruction. For each case, all patients in the control group with identical T and N stages and age ±2 years were considered. A paired control was randomly selected from this group. 10 years after primary surgery, 39 of the cases had relapsed, compared to 52 of the matched controls. The reconstructed group was analyzed for relapse dynamics after mastectomy; the first peak in relapses was similarly timed, but smaller than for the controls, while the second peak was similar in time and size. Second, the relapse pattern was analyzed with reconstruction as the starting point. A peak in recurrences was found after 18 months, and a lower peak at the 5th-6th year. The height of the peak correlated with the extent of surgery and initial T and N stages. Timing of the peak was not affected, neither was the cumulative effect. The relapse pattern, when time origin is placed both at mastectomy and at reconstruction, is bimodal with a peak position at the same time points, at 2 years and at 5-6 years. The timing of the transition from dormant micrometastases into clinically detectable macrometastases might be explained by an enhancing effect of surgery.

    Breast cancer is the most common cancer and the leading cause of cancer mortality among women of all ethnic and age groups in Malaysia. Delay in seeking help for breast cancer symptoms is preventable and by identifying possible factors for delayed diagnosis, patient prognosis and survival rates could be improved. This narrative review aimed to understand and evaluate the level of in-depth breast cancer knowledge in terms of clinical breast examination and breast self-examination, and other important aspects such as side-effects and risk factors in Malaysian females. Since Malaysia is multicultural, this review assessed social perceptions, cultural beliefs and help-seeking behaviour in respect to breast cancer among different ethnic groups, since these may impinge on efforts to 'avoid' the disease. A comprehensive literature search of seven databases was performed from December 2015 to January 2015. Screening of relevant published journals was also undertaken to identify available information related to the knowledge, perception and help-seeking behaviour of Malaysian women in relation to breast cancer. A total of 42 articles were appraised and included in this review. Generally, women in Malaysia had good awareness of breast cancer and its screening tools, particularly breast self-examination, but only superficial in-depth knowledge about the disease. Women in rural areas had lower levels of knowledge than those in urban areas. It was also shown that books, magazines, brochures and television were among the most common sources of breast cancer information. Delay in presentation was attributed mainly to a negative social perception of the disease, poverty, cultural and religion practices, and a strong influence of complementary and alternative medicine, rather than a lack of knowledge. This review highlighted the need for an intensive and in-depth breast cancer education campaigns using media and community health programmes, even with the existing good awareness of

    Silicone breast prostheses prove technically challenging when performing diffusion-weighted MR imaging in the breasts. We describe a combined fat and chemical suppression scheme to achieve dual suppression of fat and silicone, thereby improving the quality of diffusion-weighted images in women with breast implants. MR imaging was performed at 3.0 and 1.5 T in women with silicone breast implants using short-tau inversion recovery (STIR) fat-suppressed echo-planar (EPI) diffusion-weighted MR imaging (DWI) on its own and combined with the slice-select gradient-reversal (SSGR) technique. Imaging was performed using dedicated breast imaging coils. Complete suppression of the fat and silicone signal was possible at 3.0 T using EPI DWI with STIR and SSGR, evaluated with dedicated breast coils. However, a residual silicone signal was still perceptible at 1.5 T using this combined approach. Nevertheless, a further reduction in silicone signal at 1.5 T could be achieved by employing thinner slice partitions and the addition of the chemical-selective fat-suppression (CHESS) technique. DWI using combined STIR and SSGR chemical suppression techniques is feasible to eliminate or reduce silicone signal from prosthetic breast implants. (orig.)

    Mouse uteri were examined during estrus, early pregnancy, the peri-implantation period, and delayed implantation to determine whether changes in the surface coat of the luminal epithelium could be associated with receptivity of the uterus to the presence of blastocyst-stage embryos or blastocyst adhesion. By using alkaline bismuth subnitrate to label periodate-oxidized glycols within the glycocalyx we were able to measure the thickness and examine the morphology of the glycocalyx by electron microscopy. Ferritin-conjugated Ricinus communis agglutinin (RCA-I) demonstrated the presence of D-galactose at terminal, nonreducing positions within the glycocalyx. A relatively thick (0.06-0.1-micron) surface coat was present during estrus, but contained almost no RCA-I binding sites. During Day 3 of pregnancy the surface coat remained up to 0.1 micron thick and RCA-I binding sites were present. At Day 4 and during delay the glycocalyx had a fibrillar appearance, contained RCA-I binding sites, and was reduced to 0.06-0.08 micron in thickness. During Day 5 of pregnancy the thickness of the surface coat was greatly reduced, but there remained uniform lectin binding adjacent to the plasma membrane both at sites of blastocyst attachment and between implantation sites. The results indicate that the luminal epithelium of the mouse uterus acquired RCA-I binding sites during pregnancy and that the thickness of the surface coat was greatly reduced at the time of implantation.

    The potential impact of the trend toward delayed childbearing or nulliparity on future breast cancer incidence is quantitatively assessed for the Saarland/FRG. Distribution of age at first birth is estimated from vital statistics for seven five-year birth cohorts from 1936-40 to 1966-70. Estimates of the relative risks associated with age at first birth or nulliparity are based on median results of 23 controlled epidemiologic studies conducted in Europe and North America. Compared to the birth cohorts around 1940, a steady increase in incidence up to about +15% is projected for the younger cohorts indicating a substantial public health impact. Using data of the population based cancer registry of the Saarland, the cumulative incidence of breast cancer up to age 50 is calculated as 1.52% for the 1936-40 birth cohort and is projected to rise to 1.75% in the 1966-70 cohort. Similar changes in fertility patterns have been observed in other parts of the FRG. Given the continuing rise in mortality from breast cancer in the FRG this stresses the need for more effective screening procedures.

    Traditionally, narcotics have been used for analgesia after breast surgery. However, these agents have unpleasant side effects. Intercostal nerve blockade is an alternative technique to improve postoperative pain. In this study, the authors investigate outcomes in patients who receive thoracic intercostal nerve blocks for implant-based breast reconstruction. A retrospective chart review was performed. The operative technique for breast reconstruction and administration of nerve blocks is detailed. Demographic factors, length of stay, and complications were recorded. The consumption of morphine, Valium, Zofran, and oxycodone was recorded. Data sets for patients receiving thoracic intercostal nerve blocks were compared against those that did not. One hundred thirty-two patients were included. For patients undergoing bilateral reconstruction with nerve blocks, there was a significant reduction in length of stay (1.87 days versus 2.32 days; p = 0.001), consumption of intravenous morphine (5.15 mg versus 12.68 mg; p = 0.041) and Valium (22.24 mg versus 31.13 mg; p = 0.026). For patients undergoing unilateral reconstruction with nerve blocks, there was a significant reduction in consumption of intravenous morphine (2.80 mg versus 8.17 mg; p = 0.007). For bilateral reconstruction with intercostal nerve block, cost savings equaled $2873.14 per patient. For unilateral reconstruction with intercostal nerve block, cost savings equaled $1532.34 per patient. The authors' data demonstrate a reduction in the consumption of pain medication, in the hospital length of stay, and in hospital costs for patients receiving intercostal nerve blocks at the time of pectoralis elevation for implant-based breast reconstruction.

    This study aims to present the case of a female patient with Poland's syndrome and pectus excavatum deformity who underwent breast and chest wall reconstruction with a pre-shaped free deep inferior epigastric perforator flap. A 57-year-old female patient with Poland's syndrome and pectus excavatum presented with a Baker III capsular contracture following a previously performed implant-based right breast reconstruction. After a chest and abdominal CT angiography, she was staged as 2A1 chest wall deformity according to Park's classification and underwent implant removal and capsulectomy, followed by a pre-shaped free abdominal flap transfer, providing both breast reconstruction and chest wall deformity correction in a single stage operation. Post-operative course was uneventful, and the aesthetic result remains highly satisfactory 24 months after surgery. Deep inferior epigastric free flap represents an interesting reconstructive solution when treating Poland's syndrome female patients with chest wall and breast deformities.

    African American women (AAW) are 25% more likely to present with late stage breast cancer and 20% more likely to die from their disease than Caucasian women. Researchers report that a treatment delay of 3 months is a significant factor in breast cancer mortality. Socioeconomic factors, lack of access and knowledge, spiritual and religious beliefs, fear and fatalism are reported as contributing factors to screening delays. Studies have primarily applied the Health Belief Model (HBM) and modified versions like the Champion HBM to preventive health practices. Neither have significant inclusion of spirituality or religiosity. The TRA/TPB focus on beliefs, intent and attitude as individual determinants of the likelihood of performing a specific behavior; but have not had wide utility in studies related to screening delays among AAW. This paper explores the utility of applying the TRA/TPB as the theoretical framework for determining cultural relevance of spirituality and religiosity to screening delays among AAW.

    Recent advancements in barrier membranes, bone grafting substitutes, and surgical techniques have led to a predictable arsenal of treatment methods for clinicians who practice implant dentistry. The contemporary clinician is supplied with proven knowledge, substantiated materials, and instrument inventory that allows implant placement in cases that used to be reserved for the specialist in the past because of their complexity. Nowadays, postextraction alveolar ridge maintenance can be a predictable procedure and can certainly aid the clinician in preventing ridge collapse, thereby allowing for implant placement in a position that satisfies esthetics and function. Extraction socket maintenance for future implant therapy does not rule out immediate implant placement but rather provides an additional option when treatment planning implant patients. This article will focus on the concept of extraction socket preservation using regenerative materials. It will describe a technique suggested by the authors to resist bone resorption and soft tissue shrinkage following tooth extraction.

    For women who have mastectomy, breast reconstruction is an option which may improve psychosocial functioning. The purpose of this study was to evaluate changes in psychosocial functioning over a long follow-up period after mastectomy, specifically examining the differences between those with mastectomy alone and those who underwent postmastectomy delayed breast reconstruction (DBR). This was a prospective longitudinal survey study of women with mastectomy in which a repeated measures design was used to compare psychosocial function scores over 3 timepoints: 1) pre-mastectomy; 2) one year post-mastectomy; and 3) long-term post-mastectomy (mean 6.3 years). In addition, psychosocial functioning was compared between the mastectomy alone group and the group who elected for DBR. 67 women who completed questionnaires at all three time points were included. The long-term follow-up time post-mastectomy was 75.2 months (6.3 years). Twenty-eight women (41.8%) underwent DBR in the study period. For the entire cohort, between one-year and long-term post-mastectomy, there were significant improvements in scores for body concerns (P = 0.03), cancer-related distress (P = 0.01), and total distress (P = 0.04). At long-term follow-up, women with DBR had significantly higher levels of total distress (P = 0.01), obsessiveness (P = 0.03), and cancer-related distress (P = 0.02) compared to those with mastectomy alone. There were no differences in quality of life between the two groups at any time point. Psychosocial functioning improves over time in patients treated with mastectomy in the long-term breast cancer survivorship period, which may be related to the effect of time post-treatment, rather than an effect of choice for or against DBR. © 2014 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Considerable proportion of patients does not respond to the cardiac resynchronization therapy (CRT. This study investigated clinical relevance of left ventricular electrode local electrogram delay from the beginning of QRS (QLV. We hypothesized that longer QLV indicating more optimal lead placement in the late activated regions is associated with the higher probability of positive CRT response. Methods We conducted a retrospective, single–centre analysis of 161 consecutive patients with heart failure and LBBB or nonspecific intraventricular conduction delay (IVCD treated with CRT. We routinely intend to implant the LV lead in a region with long QLV. Clinical response to CRT, left ventricular (LV reverse remodelling (i.e. decrease in LV end-systolic diameter - LVESD ≥10% and reduction in plasma level of NT-proBNP >30% at 12-month post-implant were the study endpoints. We analyzed association between pre-implant variables and the study endpoints. Results Clinical CRT response rate reached 58%, 84% and 92% in the lowest (≤105 ms, middle (106-130 ms and the highest (>130 ms QLV tertile (p  Conclusion LV lead position assessed by duration of the QLV interval was found the strongest independent predictor of beneficial clinical response to CRT.

  5. One stage rescue procedure after capsular contracture of breast implants with autologous fat grafts collected by water assisted liposuction (“BEAULI Method”

    Full Text Available With increasing number of patients with silicone implants for breast augmentation or reconstruction we are confronted with more and more cases of capsular contracture. Not every case is resolved by resection of the capsule and exchange of implants. Many patients rather bear the consequences of severe fibrosis than to have their implants removed. The one stage procedure of implant removal and lipofilling proved to be highly efficient with good to excellent results and high patient satisfaction. Between January 2008 and October 2012 a total of 64 patients (124 breasts with capsular fibrosis Baker III to IV were treated with autologous fat grafts collected with the body-jet by water-assisted liposuction (“BEAULI Method”. Magnetic resonance imaging (MRI of the breasts was performed in 5 patients preoperatively and 6 month postoperatively, a clinical examination and photo documentation of all patients was done on day 1 and after 4 weeks, 12 weeks and 6 months postoperatively. The procedure included implant removal and lipofilling of the subcutaneous and intramuscular space in a single procedure by means of the BEAULI Method. The average gross amount of grafted fat was 260 ml. The average drainage time was one day. The shape of the breast changed to a more natural and ptotic form. Negative side effects like oily cysts or infections were not observed. The time of the overall procedure including liposuction was 70±15 min. Reoccurring capsular contracture is one of the hazards in plastic surgery. Until now the treatment of choice after more than two failed implant changes combined with resection of the capsule is usually the final removal of implants with or without possible additional autologous tissue transfer (microvascular flaps. We could add a relatively simple and efficient procedure to resolve and improve those cases by autologous fat transfer using water-assisted liposuction and the BEAULI Method.

    We treated randomly 75 premenopausal patients with advanced breast cancer with combination chemotherapy (5-fluorouracil, cyclophosphamide and prednisone), either as an early adjunct to oophorectomy or as a delayed treatment upon appearance of progressive metastatic disease after operation. The group receiving early systemic chemotherapy enjoyed an improved response rate, an improved survival rate and, most importantly, an improved progression-free interval (median of 53 versus 17 weeks). With the exclusion of the group with early (within three weeks after oophorectomy) progression, the progression-free intervals had a median duration of 77 weeks in the early-treatment group versus 33 weeks in the control group. The early-progression group did exceedingly poorly, although systemic chemotherapy was employed at that juncture, having a median survival of 22 weeks as compared to 144 weeks in the immediate-treatment group and 105 weeks in the control group.

    To report a rare case of delayed Type IIIb endoleak secondary to fabric tear following implantation of a Medtronic Talent endovascular device. A 83-year old gentleman underwent elective endovascular aneurysm repair for infrarenal abdominal aortic aneurysm with a Medtronic bifurcated stent graft in 2008. Seven years after the initial repair, imaging surveillance revealed significant endoleak and brisk aneurysm sac expansion due to Type IIIb endoleak secondary to endograft limb fabric tear. This case illustrates the imperative role of imaging surveillance in detection of long-term endovascular aneurysm repair complications. Furthermore, we discuss exclusion of the graft tear with aortouniiliac stent grafting as the treatment for this complication.

    Implant-associated anaplastic large cell lymphoma (ALCL) is the subject of much debate in the field of plastic surgery. Only a few published cases have been reported and the rarity of the disease may make proving causality exceedingly difficult. Despite this, it is of utmost importance that full attention be devoted to this subject to ensure the safety and well-being of patients. The authors report one new case of implant-associated ALCL that recently presented to their institution. Implant-associated ALCL is a poorly understood disease. It should likely be considered its own clinical entity and categorized into two subtypes: one presenting as a seroma and the other as a distinct mass or masses. When reported, only textured implants have been associated with ALCL. The United States Food and Drug Administration and American Society of Plastic Surgeons have initiated a registry and have collected critical data to gain further understanding of this disease.

    Staged expander-to-implant breast reconstruction is plagued by a high prevalence of complications. We have employed an alternative approach of using the infra-mammary crease (IMF) for expander-to-implant exchange. The IMF approach was thought to utilize healthier tissues, which are believed to be less affected by the process of tissue expansion, and reside distant from the field of the radiotherapy boost. A retrospective chart review was performed on all patients undergoing a staged implant-based breast reconstruction from 2009 to 2014. Patients were divided into those that received an IMF vs. a mastectomy scar (MS) approach in the second stage of expander-to-implant exchange. Patient characteristics and postoperative complications were extracted. A total of 75 patients undergoing 96-staged reconstructions were included (70 cases MS vs. 26 cases IMF). Patient demographics and implant characteristics were similar between groups. There were no significant differences in overall complications between the groups (11.4% MS vs. 7.7% IMF, P=0.72). All cases of implant exposure occurred in the MS group and had a history of radiation. However, there was no statistical difference in implant exposure between groups (4.3% MS vs. 0% IMF, P=0.56) or in the irradiated patients subgroup (20% MS vs. 0% IMF, P=0.25). In conclusion, the IMF approach for the second stage of expander-to-implant exchange is an alternative technique with a similar prevalence of complications as the traditional mastectomy scar approach. This technique may prove useful in reducing postoperative incisional dehiscence and implant exposure, especially in the context of radiotherapy. Copyright © 2016. Published by Elsevier Masson SAS.

  11. 3D CT-based high-dose-rate breast brachytherapy implants: treatment planning and quality assurance.

    Although accelerated partial breast irradiation (APBI) as the sole radiation modality after lumpectomy has shown promising results for select breast cancer patients, published experiences thus far have provided limited information on treatment planning methodology and quality assurance measures. A novel three-dimensional computed tomography (CT)-based treatment planning method for accurate delineation and geometric coverage of the target volume is presented. A correlation between treatment volume and irradiation time has also been studied for quality assurance purposes. Between May 2002 and January 2003, 50 consecutive patients underwent an image-guided interstitial implant followed by CT-based treatment planning and were subsequently treated with APBI with a high-dose-rate (HDR) brachytherapy remote afterloader. Target volume was defined as the lumpectomy cavity +2 cm margin modified to >/=5 mm to the skin surface. Catheter reconstruction, geometric optimization, and manual adjustment of irradiation time were done to optimally cover the target volume while minimizing hot spots. Dose homogeneity index (DHI) and percent of target volume receiving 100% of the prescription dose (32 Gy in 8 fractions or 34 Gy in 10 fractions) was determined. Additionally, the correlation between the treatment volume and irradiation time, source strength, and dose was then analyzed for manual verification of the HDR computer calculation. In all cases, the lumpectomy cavity was covered 100%. Target volume coverage was excellent with a median of 96%, and DHI had a median value of 0.7. For each plan, source strength times the treatment time for every unit of prescribed dose had an excellent agreement of +/-7% to the Manchester volume implant table corrected for modern units. CT-based treatment planning allowed excellent visualization of the lumpectomy cavity and normal structures, thereby improving target volume delineation and optimal coverage, relative to conventional orthogonal film

    Staged expander-implant breast reconstruction (EIBR) and microsurgical abdominal flap breast reconstruction (MAFBR) are the most common modes of breast reconstruction (BR) in the United States. Whether the mode of breast reconstruction has an impact on patient quality of life (QoL) and satisfaction remains a question. A retrospective study was conducted identifying a population of 119 patients who underwent unilateral immediate BR. Only patients who were eligible for either EIBR or MAFBR based on preoperative characteristics were included in the study. The following parameters were retrieved: demographics, mode of reconstruction, cancer, recovery, QoL, and patient satisfaction. The latter two parameters were determined using the BREAST-Q BR module questionnaire. Two-way analysis of variance with mode of reconstruction and occurrence of complication as independent variables was used to determine the effect on patient satisfaction and QoL. The association between mode of reconstruction and patient response with each item of the QoL and satisfaction survey domains was analyzed. The overall response rate was 62.2 %. Non-respondents and respondents did not significantly differ in demographics, surgery type, cancer staging, adjuvant therapy, and complication rate. Age and BMI were significantly higher in MAFBR, while level of education was higher in EIBR. MAFBR had higher scores in psychosocial and sexual wellbeing, satisfaction with outcome, breast, information, and plastic surgeon when compared with patients who underwent EIBR. For patients eligible for both MAFBR and EIBR, MAFBR is associated with higher levels of satisfaction and QoL. Comprehensive pre-operative information of pros and cons of both modes of BR is crucial for patients to make a well-informed decision, thus, resulting in higher levels of satisfaction.

    Malignant metastases to the heart and pericardium, which occur far more often than do primary cardiac neoplasms, typically lead to fatal outcomes. The phyllodes tumor is a rare, predominantly benign fibroepithelial breast neoplasm with variable malignancy potential. Herein, we describe the case of a 35-year-old woman who, 3 years after undergoing a simple mastectomy for a rapidly enlarging breast neoplasm, presented with cardiogenic shock and was found to have a large right ventricular tumor that obstructed the right ventricular outflow tract. Despite successful resection of the ventricular mass and a right atrial mass of organized thrombus, the patient died 8 days postoperatively of multiorgan failure due to severe right ventricular dysfunction. Histopathologic analysis determined that the right ventricular mass was a malignant, metastatic phyllodes tumor. To our knowledge, this is only the 2nd reported case of a phyllodes tumor that metastasized to the heart and presented as an intracavitary mass with cardiogenic shock. In addition to discussing our patient's case, we review the pertinent medical literature.

    Seroma formation is the most common early postoperative complication after pectus excavatum repair, but later seromas are rare. While many seromas eventually resorb or decrease in size after aspiration, our case demonstrates recurrent seroma formation as a late complication of pectus excavatum repair in a patient with an implant tear. Postoperative seromas can result in prolonged chest wall pain, large chest wall masses, and increased mass effect on the heart with potential risk for resultant right ventricular outflow obstruction. This case report illustrates a solid silicone implant tear. Though rare, early recognition may help to decrease the likelihood of recurrent postoperative seromas. (orig.)

    In 2008, the authors' institution adopted a policy requiring that all patients, regardless of preoperative risk, receive both sequential compression devices and a single preoperative subcutaneous 5000 unit injection of heparin. A previously published 12-year review at this same institution before this policy demonstrated a 1.5% 30-day postoperative incidence of hematoma in primary augmentation or delayed tissue expander based breast reconstructions. To determine the incidence of postoperative bleeding complications associated with preoperative administration of 5000 units of subcutaneous heparin and compare that incidence with previously published data. Patient data were collected prospectively and maintained in a secure database at a single institution with institutional review board approval. Current procedural terminology and International Classification of Diseases, Ninth Revision, coding was then used to identify all patients who received either primary breast augmentation or delayed tissue expander based breast reconstruction during a five-year period. The primary outcome was the incidence of postoperative bleeding complication. A bleeding complication was defined as any hemorrhagic event that required a return to the operating room. The overall incidence of significant postoperative bleeding was 1.47% (five of 340 [1.16% augmentation, 2.50% expander]). Comparing the current results with the previously published data, demonstrated an OR of 0.98 (95% CI 0.38 to 2.55). In women undergoing primary breast augmentation or delayed tissue expander breast reconstruction, heparin prophylaxis did not increase the risk for significant postoperative bleeding compared with historical controls.

    Alloderm was the first acellular dermal matrix used and remains a popular choice among plastic surgeons. However, while the overall surgical outcome of breast reconstruction using alloderm has been a success, the economic burden on the health care system makes it a subject of frequent re-evaluations in cost-effectiveness. Prompted by the high price of $3,700 USD for a 6 cm × 16 cm area, our group proposes the meshing of AlloDerm to decrease the total amount needed for breast reconstruction, while achieving comparable surgical outcomes as using unmeshed alloderm.

    Purpose: To evaluate the long-term toxicity, cosmesis, and local control of accelerated partial breast irradiation with implant brachytherapy after wide local excision for Stage T1N0 breast cancer (BCa). Materials and Methods: Between 1997 and 2001, 50 patients with Stage T1N0M0 BCa were treated in a Phase I-II protocol using low-dose-rate accelerated partial breast irradiation with implant brachytherapy after wide local excision and lymph node surgery. The total dose was escalated in three groups: 50 Gy (n = 20), 55 Gy (n = 17), and 60 Gy (n = 13). Patient- and physician-assessed breast cosmesis, patient satisfaction, toxicity, mammographic abnormalities, repeat biopsies, and disease status were prospectively evaluated at each visit. Kendall's tau ({tau}{sub {beta}}) and logistic regression analyses were used to correlate outcomes with dose, implant volume, patient age, and systemic therapy. Results: The median follow-up period was 11.2 years (range, 4-14). The patient satisfaction rate was 67%, 67% reported good-excellent cosmesis, and 54% had moderate-severe fibrosis. Higher dose was correlated with worse cosmetic outcome ({tau}{sub {beta}} 0.6, p < .0001), lower patient satisfaction ({tau}{sub {beta}} 0.5, p < .001), and worse fibrosis ({tau}{sub {beta}} 0.4, p = .0024). Of the 50 patients, 35% had fat necrosis and 34% developed telangiectasias {>=}1 cm{sup 2}. Grade 3-4 late skin and subcutaneous toxicities were seen in 4 patients (9%) and 6 patients (13%), respectively, and both correlated with higher dose ({tau}{sub {beta}} 0.3-0.5, p {<=} .01). One patient had Grade 4 skin ulceration and fat necrosis requiring surgery. Mammographic abnormalities were seen in 32% of the patients, and 30% underwent repeat biopsy, of which 73% were benign. Six patients had ipsilateral breast recurrence: five elsewhere in the breast, and one at the implant site. One patient died of metastatic BCa after recurrence.

    Pharmacological targeting of transcription factors holds great promise for the development of new therapeutics, but strategies based on blockade of DNA binding, nuclear shuttling, or individual protein partner recruitment have yielded limited success to date. Transcription factors typically engage in complex interaction networks, likely masking the effects of specifically inhibiting single protein-protein interactions. Here, we used a combination of genomic, proteomic and biophysical methods to discover a suite of protein-protein interactions involving the SOX18 transcription factor, a known regulator of vascular development and disease. We describe a small-molecule that is able to disrupt a discrete subset of SOX18-dependent interactions. This compound selectively suppressed SOX18 transcriptional outputs in vitro and interfered with vascular development in zebrafish larvae. In a mouse pre-clinical model of breast cancer, treatment with this inhibitor significantly improved survival by reducing tumour vascular density and metastatic spread. Our studies validate an interactome-based molecular strategy to interfere with transcription factor activity, for the development of novel disease therapeutics.

    Full Text Available [english] Implantation of breast prosthesis is still one of the most frequently performed breast reconstructing or contouring procedures. Infectious complications and capsular contracture are inherent problems that may have different causes which are not clearly defined yet in terms of pathophysiology. Recent findings showed bacterial contamination as a major cause of implant failure. Since this has direct implications for the surgical management we report on biofilm development on alloplastic breast prostheses, characteristics and effects after implantation of medical devices in general. This article gives a review of the current literature and discusses possible issues to solve the problem of infection after implantation of breast prosthesis. In conclusion the reinsertion of single-use devices should not be recommended and should be strictly avoided when a device related infection has occured. According to current knowledge contaminated implants should be removed, the infection then be cured and if necessary, a new prosthesis may be implanted after a regeneration period. Alternatively a change in therapy towards autologous tissue reconstruction should be considered if previous attempts with alloplastic prostheses have failed and if radiation therapy has worsened the local tissue situation in the recipient area.[german] Implantationen von Brust-Prothesen sind für Brustrekonstruktionen oder Konturierungen noch immer die am häufigsten durchgeführten Verfahren. Typische inhärente Probleme sind dabei neben infektiösen Komplikationen die Kapselkontrakturen, deren unterschiedliche Ursachen bezüglich der Pathophysiologie noch nicht eindeutig geklärt sind.Neuere Erkenntnisse weisen auf bakterielle Kontamination als eine der Hauptursachen von Implantatversagen hin. Da dies direkte Auswirkungen auf die chirurgische Behandlung hat, berichten wir über das Problem der Biofilmentwicklung auf alloplastischen Brustimplantaten sowie über deren Effekte

    Full Text Available Los tres planos de colocación de implantes para aumento mamario tienen particularidades claramente identificables. Cada modificación anatómica y los elementos tisulares acompañantes establecen beneficios y efectos adversos que influyen sobre el resultado final. El presente estudio tiene como objetivo la comunicación temprana de los hallazgos clínicos obtenidos con la creación de una cavidad de implantación en diferentes condiciones, utilizando una combinación de planos y haciendo énfasis en un fundamento anatómico y funcional de gran relevancia. El mejor manejo de los implantes mamarios y de otros biomateriales es el mantenimiento de su integridad y el control de su comportamiento a largo plazo. De manera prospectiva valoramos la colocación de implantes mamarios en una cavidad que es subfascial en la porción caudal de la mama y retropectoral en la porción cefálica. El aislamiento de las rutas linfáticas suprafasciales proporciona un menor riesgo de contaminación del implante. La facilidad técnica se produce al no tener que desinsertar inferior y medialmente el músculo pectoral. En los 15 casos estudiados, no se produjo ningún desplazamiento cefálico de los implantes con la contracción pectoral. Hacemos también una revisión de la sustentación anatómica y funcional del nuevo plano de implantación utilizado. El resultado es una suma de beneficios y la prevención de un frecuente efecto adverso, con lo que cumplimos el objetivo final de reducir la morbilidad e incrementar la seguridad del procedimiento.The particular benefits and adverse effects of the three different planes for breast implant placement are widely known. The search for a safer implantation cavity led to a combination of two dissection planes with different anatomical components placed in continuity. Instead of supporting its value with statistics of good outcomes, emphasis is stressed in the functional and anatomical consequences of the proposed plane of

    This paper reviews the evaluation of the breast of women by MR-techniques after implantation with silicon gel protheses. The main topics are the diagnosis of implant defects such as extensive ''gel bleed'' and intra- and extracapsular ruptures. Moreover, the MR-detection of siliconomas (encapsulated silicone) and differentiation from malignomas as well as MR-features of chronic foreign body reactions are presented. ''Gel bleed'' is difficult to diagnose unambiguously by MRI alone. The ''linguini'' sign is the only reliable mans to diagnose intracapsular ruptures. The presence of silicone outside the implant capsule indicates extracapsular rupture. The MR-spectroscopic detection of silicone in the liver suggests after short implantation times and a normal MR scan the diagnosis ''gel bleed'', and after longer implantation times of more than 10 years and missing ''linguini'' sign the diagnosis of ruptures due to a dissolved shell of the implant. MRI, in comparison to other imaging modalities, has the highest specificity and sensitivity in the diagnosis of implant defects. Due to its high costs, however, MR is not suitable as a screening tool and should only be used in cases of sonographic suspected rupture or after radical mastectomy. In these cases MRI is the method of choice. (orig.) [German] In dieser Uebersicht wird die Evaluation der weiblichen Brust nach Aufbau mit Silikonmammaprothesen mittels MR-Techniken vorgestellt.

    Reported complication rates of implant-based breast reconstruction in the literature exceed 50%, with mastectomy skin flap necrosis reported to occur in up to 25% of cases. Laser-assisted indocyanine green angiography (LA-ICGA) technology allows the surgeon to optimize preservation of the mastectomy skin flap while avoiding skin necrosis. The purpose of this study was to determine if outcomes of breast reconstruction are beneficially affected by using LA-ICGA. A total 269 consecutive women (467 breast reconstructions) undergoing implant-based breast reconstruction from 2008 to 2013 were examined. The complication rates of those who underwent reconstruction prior to the implementation of LA-ICGA were compared with those who were reconstructed after implementation of LA-ICGA. A total of 254 consecutive breast reconstructions were performed prior to implementation of LA-ICGA, and 213 breasts were reconstructed with the use of LA-ICGA. After implementation of LA-ICGA System, the rate of mastectomy skin flap necrosis decreased by 86% (6.7% versus 0.9%, p = 0.02). The overall complication rate prior to LA-ICGA was 13.8% compared with 6.6% with the use of LA-ICGA (p = 0.01). After LA-ICGA was incorporated, the percentage of patients undergoing single-stage reconstruction increased from 12% to 32% (p = <0.001). Implementation of LA-ICGA provides the surgeon with an objective assessment of mastectomy flap perfusion resulting in a trend toward overall reduction in complications as well as an 86% decrease in the rate of subsequent skin necrosis. The objective assessment of mastectomy flap perfusion allows the surgeon to tailor breast reconstruction intraoperatively, in real-time, adjusting for the individual patient's mastectomy flap perfusion. © 2016 Wiley Periodicals, Inc.

    Preoperative evaluation of social interaction and global development levels using the Vineland Social Maturity Scale (VSMS) and Bayley Scales of Infant Development-2nd edition (BSID-II) may be beneficial in predicting the postoperative outcome in pediatric cochlear implant recipients. In particular, cautious preoperative counseling regarding the poor postoperative prognosis may be necessary in children with low social skills and developmental status. To determine the clinical benefit of preoperative evaluation of social interaction and global development levels using VSMS and BSID-II in predicting the postoperative outcome in pediatric cochlear implant recipients. A total of 65 deaf children who underwent cochlear implantation (CI) were included in this study. Age at the time of implantation ranged from 12 to 76 months. All of the children underwent a comprehensive preimplant psychological assessment by a clinical psychologist. The VSMS and BSID-II were used for evaluating social skills and a child's development preoperatively. A social quotient (SQ) was calculated by using the VSMS for each subject using the following formula: (social age/chronological age) × 100. The auditory perception and speech production abilities were evaluated using the Categories of Auditory Performance (CAP) scale and the Korean version of the Ling's stage (K-Ling), respectively, at 1 year after CI. The associations between the preoperative SQ/developmental levels and the postoperative auditory/speech outcomes were evaluated. The mean SQ was significantly decreased in the enrolled children (90.6 ± 26.1). The improvement in CAP score at 1 year after CI was correlated with preoperative SQ. The improvements in phonemic and phonologic levels of K-Ling were correlated with preoperative VSMS and BSID-II scores.

    An in-pool small animal irradiation neutron tube (SAINT) facility was designed, constructed and installed at the University of Virginia Nuclear Research Reactor (UVAR). Thermal neutron flux profiles were measured by foil activation analysis (gold) and verified with DORT and MCNP computer code models. The gamma-ray absorbed dose in the neutron-gamma mixed field was determined from TLD measurements. The SAINT thermal neutron flux was used to investigate the well characterized human breast cancer cell line MCF-7B on both in-vitro samples and in- vivo animal subjects. Boronophenylalanine (BPA enriched in 95% 10B) was used as a neutron capturing agent. The in-vitro response of MCF-7B human breast carcinoma cells to BPA in a mixed field of neutron-gamma radiation or pure 60Co gamma radiation was investigated. The best result (lowest surviving fraction) was observed in cell cultures pre-incubated with BPA and given the neutron irradiation. The least effective treatment consisted of 60Co irradiation only. Immunologically deficient nude mice were inoculated subcutaneously with human breast cancer MCF-7B cells and estradiol pellets (to support tumor growth). The tumor volume in the mouse control group increased over time, as expected. The group of mice exposed only to neutron treatment exhibited initial tumor volume reduction lasting until 35 days following the treatment, followed by renewed tumor growth. Both groups given BPA plus neutron treatment showed continuous reduction in tumor volume over the 55-day observation period. The group given the higher BPA concentration showed the best tumor reduction response. The results on both in-vitro and in-vivo studies showed increased cell killing with BPA, substantiating the incorporation of BPA into the tumor or cell line. Therefore, BNCT may be a possible choice for the treatment of human breast carcinoma. However, prior to the initiation of any clinical studies, it is necessary to determine the therapeutic efficacy in a large

    Purpose: Capsular contracture (CC) is a serious complication in patients receiving implant-based reconstruction for breast cancer. The goal of this study was to identify image-based correlates of CC using MRI imaging in breast cancer patients who received both MRI and clinical evaluation following reconstructive surgery. Methods: We analyzed a retrospective dataset of 50 patients who had both a diagnostic MR and a plastic surgeon’s evaluations of CC score (Baker’s score) within a six month period following mastectomy and reconstructive surgery. T2w sagittal MRIs (TR/TE = 3500/102 ms, slice thickness = 4 mm) were used for morphological shape features (roundness, eccentricity, solidity, extent and ratio-length) and histogram features (median, skewness and kurtosis) of the implant and the pectoralis muscle overlying the implant. Implant and pectoralis muscles were segmented in 3D using Computation Environment for Radiological Research (CERR) and shape and histogram features were calculated as a function of Baker’s score. Results: Shape features such as roundness and eccentricity were statistically significant in differentiating grade 1 and grade 2 (p = 0.009; p = 0.06) as well as grade 1 and grade 3 CC (p = 0.001; p = 0.006). Solidity and extent were statistically significant in differentiating grade 1 and grade 3 CC (p = 0.04; p = 0.04). Ratio-length was statistically significant in differentiating all grades of CC except grade 2 and grade 3 that showed borderline significance (p = 0.06). The muscle thickness, median intensity and kurtosis were significant in differentiating between grade 1 and grade 3 (p = 0.02), grade 1 and grade 2 (p = 0.03) and grade 1 and grade 3 (p = 0.01) respectively. Conclusion: Morphological shape features described on MR images were associated with the severity of CC. MRI may be important in objectively evaluating outcomes in breast cancer patients who undergo implant reconstruction.

    Full Text Available This study aims to present the case of a female patient with Poland′s syndrome and pectus excavatum deformity who underwent breast and chest wall reconstruction with a pre-shaped free deep inferior epigastric perforator flap. A 57-year-old female patient with Poland′s syndrome and pectus excavatum presented with a Baker III capsular contracture following a previously performed implant-based right breast reconstruction. After a chest and abdominal CT angiography, she was staged as 2A1 chest wall deformity according to Park′s classification and underwent implant removal and capsulectomy, followed by a pre-shaped free abdominal flap transfer, providing both breast reconstruction and chest wall deformity correction in a single stage operation. Post-operative course was uneventful, and the aesthetic result remains highly satisfactory 24 months after surgery. Deep inferior epigastric free flap represents an interesting reconstructive solution when treating Poland′s syndrome female patients with chest wall and breast deformities.

Breast implants are industrial elastomers that may result with electrostatic charges on its surface. Its propper resistivity allows silicone to maintain enough static that atracts and adheres particulate matter to become surface contamination with periprosthetic tissue reaction. Recognition of this particular physical property and its clinical implications allows for safer conditions of practice. We review microbiology involved in periprosthetic capsular formation and infection by "biofilm" producer bacteria.

    Acellular dermal matrix (ADM) is commonly used for tissue expander/implant breast (TE/I-based) reconstruction. But the relation between ADM and postoperative complications remains controversial. A few meta-analyses were conducted in 2011-2012 and the result revealed that ADM can increase the risk of complications. The purpose of our study is to offer updated evidence for ADM clinical application by analyzing the effect of ADM on complications of TE/I-based breast reconstruction. The literature published from January 2010 to February 2015 was searched in EMbase, Medline, Science Direct, the Cochrane Central Register of Controlled Trials (CENTRAL), CBMdisc, CNKI, VIP, and the references of those included studies were also searched by hand. According to inclusive criteria, 11 studies were selected and the values were extracted from the included literature. Complications with four different categories assigned for overall complications, infection, hematoma/seroma, and explantation were collected. RevMan 5.1 was used for meta-analysis. The evidence level was assessed by using the GRADE system. Eleven published studies were included. The results showed that compared to the control group, the ADM group increased the rate of overall complications (OR = 1.33, 95% CI 1.03-1.70, p = 0.03), infection (OR = 1.47, 95% CI 1.04-2.06, p = 0.03), hematoma/seroma (OR = 1.66, 95% CI 1.13-2.44, p = 0.01), but there was no significant difference in explantation (OR = 1.37, 95% CI 0.89-2.11, p = 0.15). Based on the GRADE system, all the evidence was at level C and weak recommendation. In TE/I-based breast reconstruction, ADM increased the incidence of overall complications, infection, and hematoma/seroma; the incidence of explantation remains unknown. For the poor quality of the original studies, a prudent choice is suggested; and more high-quality, large-sample studies are needed. This journal requires that authors assign a level of evidence to each submission to which Evidence

    Prosthetic management of thin alveolar ridges in the edentulous mandibles of elderly patients, especially the time of loading, the number of implants needed, and patient expectations and perception, is a challenge in implant dentistry. Survival of conventionally and immediately loaded 2-piece reduced-diameter implants in the interforaminal region of the edentulous mandible supporting locator-analog attachments was evaluated. Prosthetic complications and peri-implant hygiene were also studied, and patient expectation and subjective evaluation of the treatment were documented. Twenty-five patients with adapted complete dentures received 4 reduced-diameter implants. All anterior implants were immediately loaded. Three months later, patients were allocated by randomization to 1 of 2 treatment groups: 2 locator-analog attachments on the anterior implants (Group A); or 4 locator-analog attachments (Group B). After another 3 months patient allocation was changed (crossover design) for the next 3 months. Questionnaires with Likert scales and numeric rating scales were used to assess patients' expectations and subjective overdenture-related variables, respectively. One implant was lost in the immediate-loading group. Survival was 98% and 100% for immediate and delayed loading, respectively. During 12-month observation, 8 complications required aftercare. At the beginning of treatment, patients' expectations were highly positive. Subjective assessment of overdenture-related variables 3 months after immediate loading of 2 implants revealed a statistically significant improvement for most of the variables studied; this was maintained 1 year later. In the subjective assessments, there were no statistically significant differences between Groups A and B. Immediate loading of reduced-diameter implants supporting locator-analog attachments resulted in high implant survival, few prosthetic complications, good oral hygiene, and improvement of subjective denture perception in the

    Purpose: To analyze patient-, disease-, and treatment-related factors for their impact on cosmetic outcome (CO) after interstitial multicatheter accelerated partial-breast irradiation (APBI). Patients and Methods: Between April 2001 and January 2005, 171 patients with early breast cancer were recruited in Erlangen for this subanalysis of the German-Austrian APBI phase II-trial. 58% (99/171) of the patients received pulsed-dose-rate (PDR), and 42% (72/171) high-dose-rate (HDR) brachytherapy. Prescribed reference dose for HDR brachytherapy was 32 Gy in eight fractions of 4 Gy, twice daily. Prescribed reference dose in PDR brachytherapy was 49.8 Gy in 83 consecutive fractions of 0.6 Gy each hour. Total treatment time was 3-4 days. Endpoint of this evaluation was the CO, graded as excellent, good, fair, or poor. Patients were divided in two groups with an excellent (n = 102) or nonexcellent (n = 69) cosmetic result. Various factors were analyzed for their impact on excellent CO. Results: The median follow-up time was 52 months (range: 21-91 months). Cosmetic results were rated as excellent in 59.6% (102/171), good in 29.8% (51/171), fair in 9.9% (17/171), and poor in 0.6% (1/171). The initial cosmetic status was significantly worse for the nonexcellent CO group (p = 0.000). The percentage of patients who received PDR brachytherapy APBI was higher in the nonexcellent CO group (68.1% vs. 51%; p = 0.026). Acute toxicity was higher in the nonexcellent CO group (24.6% vs. 12.7%; p = 0.045). Furthermore, the presence of any late toxicity was found to be associated with a worse cosmetic result (65.2% vs. 18.6%; p = 0.000). In detail, the appearance of skin hyperpigmentation (p = 0.034), breast tissue fibrosis (p = 0.000), and telangiectasia (p = 0.000) had a negative impact on CO. Conclusion: The initial, surgery-associated cosmetic status, brachytherapy modality, and the presence of acute and late toxicities were found to have an impact on overall CO. Our data have proven

The concepts of body image, wholeness, and overall well-being have been introduced to explain the paramount psychological influence the breast has on both individuals and society as a whole. Hence, a growing subspecialty has been established to recreate or simulate the lost breast. At least one third of breast cancer victims consider breast reconstruction. Breast reconstruction post mastectomy may be offered at the time of mastectomy or delayed post mastectomy after adjuvant therapy. This may be utilizing autologous tissues or implants and each has risks and benefits, especially when considering adjuvant therapy. In addition, there has been a move away from a traditional mastectomy to less invasive, but still curative procedures, such as skin-sparing and nipple-sparing mastectomy. These procedures provide the breast envelope to facilitate reconstruction. This paper reviews the primary issues in breast reconstruction, as well as their psychologic, oncologic, and social impact.Keywords: breast restoration, body image, breast reconstruction, mastectomy

    Background: Complication rates and surgical outcomes are well reported for implant-based breast reconstruction (IBBR) using supportive materials for the inferior pole of the breast. Patient-reported outcomes (PRO) are underrepresented. The aim of this study was to compare PRO in IBBR using implants alone or in combination with a synthetic mesh. Methods and Methods: PRO was measured in patients undergoing IBBR alone or in combination with a titanium-covered polypropylene mesh (TiLOOP® Bra). In this non-randomized observational trial PRO was retrospectively assessed using the validated self-reporting BREAST-Q. The raw responses of all questions applied in each domain and transformed BREAST-Q data using the Q-Score are presented. Results: Of 90 eligible women, 42 received IBBR alone and 48 received IBBR in combination with mesh. No differences in complication rates were observed. The return rate was 67.7 % and was comparable between the groups (p = 0.117). PRO revealed no differences regarding satisfaction with breast shape (p = 0.079), outcome (p = 0.604), nipple sensitivity (p = 0.502), preoperative information (p = 0.195), office staff (p = 0.462), psychosocial well-being (p = 0.370), sexual well-being (p = 0.508) and physical well-being (p = 0.654). Significant differences were noted regarding satisfaction with the surgeon (p = 0.013) and medical staff (p = 0.035) as well as the response behavior of certain questions of the sub-domains, thus helping to further stratify PRO with regards to aesthetic outcome. However, no differences were observed in the main BREAST-Q results. Conclusion: Use of the TiLOOP® Bra in IBBR results in comparable BREAST-Q scores compared with IBBR alone. Evaluating the BREAST-Q sub-domains helps to stratify PRO more profoundly and assists in interpreting the overall results and specific research questions.

In a prevention setting, treatment with Cmpd-1 markedly delayed the growth of primary tumors in both models, and reduced the onset and severity of osteolytic lesions in the MDA-MB-231 intracardiac model. Intervention treatment with Cmpd-1 on established MDA-MB-231 primary tumors also significantly inhibited subsequent growth. In contrast, no effects of Cmpd-1 were observed on soft organ metastatic burden following intracardiac or mammary fat pad inoculations of MDA-MB-231 and 4T1.2-Luc cells respectively. MMP13 immunostaining of clinical primary breast tumors and experimental mice tumors revealed intra-tumoral and stromal expression in most tumors, and vasculature expression in all. MMP13 was also detected in osteoblasts in clinical samples of breast-to-bone metastases. The data suggest that MMP13-selective inhibitors, which lack musculoskeletal side effects, may have therapeutic potential both in primary breast cancer and cancer-induced bone osteolysis.

    Background: Breast cancer is the most frequent malignant tumor in women worldwide. In recent years, defined reconstruction principles along with numerous surgical techniques with volume replacement have been published. Autologous breast reconstruction is more natural but leaves donor site morbidity. It provides the opportunity to restore the breast mound without the need for scars. This study aims to evaluate the complications of radiotherapy after immediate breast reconstructi...

    To elucidate the quality of tissue-engineered cartilage after an autologous chondrocyte implantation (ACI) technique with Atelocollagen gel as a scaffold in the knee in the short- to midterm postoperatively, we assessed delayed gadolinium-enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) and T2 mapping and clarified the relationship between T1 and T2 values and clinical results. In this cross-sectional study, T1 and T2 mapping were performed on 11 knees of 8 patients (mean age at ACI, 37.2 years) with a 3.0-T MRI scanner. T1{sub implant} and T2{sub implant} values were compared with those of the control cartilage region (T1{sub control} and T2{sub control}). Lysholm scores were also assessed for clinical evaluation. The relationships between the T1 and T2 values and the clinical Lysholm score were also assessed. There were no significant differences in the T1 values between the T1{sub implant} (386.64 ± 101.78 ms) and T1{sub control} (375.82 ± 62.89 ms) at the final follow-up. The implants showed significantly longer T2 values compared to the control cartilage (53.83 ± 13.89 vs. 38.21 ± 4.43 ms). The postoperative Lysholm scores were significantly higher than the preoperative scores. A significant correlation was observed between T1{sub implant} and clinical outcomes, but not between T2{sub implant} and clinical outcomes. Third-generation ACI implants might have obtained an almost equivalent glycosaminoglycan concentration compared to the normal cartilage, but they had lower collagen density at least 3 years after transplantation. The T1{sub implant} value, but not the T2 value, might be a predictor of clinical outcome after ACI. (orig.)

    The introduction of biological and synthetic meshes has revolutionised the practice of implant-based breast reconstruction (IBBR) but evidence for effectiveness is lacking. The iBRA (implant Breast Reconstruction evAluation) study is a national trainee-led project that aims to explore the practice and outcomes of IBBR to inform the design of a future trial. We report the results of the iBRA National Practice Questionnaire (NPQ) which aimed to comprehensively describe the provision and practice of IBBR across the UK. A questionnaire investigating local practice and service provision of IBBR developed by the iBRA Steering Group was completed by trainee and consultant leads at breast and plastic surgical units across the UK. Summary data for each survey item were calculated and variation between centres and overall provision of care examined. 81 units within 79 NHS-hospitals completed the questionnaire. Units offered a range of reconstructive techniques, with IBBR accounting for 70% (IQR:50-80%) of participating units' immediate procedures. Units on average were staffed by 2.5 breast surgeons (IQR:2.0-3.0) and 2.0 plastic surgeons (IQR:1.0-3.0) performing 35 IBBR cases per year (IQR:20-50). Variation was demonstrated in the provision of novel different techniques for IBBR especially the use of biological (n = 62) and synthetic (n = 25) meshes and in patient selection for these procedures. The iBRA-NPQ has demonstrated marked variation in the provision and practice of IBBR in the UK. The prospective audit phase of the iBRA study will determine the safety and effectiveness of different approaches to IBBR and allow evidence-based best practice to be explored.

    Prophylactic skin-sparing mastectomy (SSM) and nipple-sparing mastectomy (NSM) both are associated with major risk reduction in women with high breast cancer risk. Skin-sparing mastectomy followed by nipple-areola complex (NAC) reconstruction is standard of care, but NSM is increasingly being performed. Preservation of the NAC in NSM may increase patient satisfaction. Therefore, we measured NAC sensitivity after NSM and compared patient satisfaction as well as body image after SSM with NSM. Women who underwent prophylactic bilateral SSM or NSM and immediate implant breast reconstruction between 2002 and 2012 were eligible. Patient satisfaction was assessed using the Breast-Q reconstruction questionnaire, body image using Hopwood's body image scale (BIS), and satisfaction with the (reconstructed) NAC using a study-specific questionnaire. In the NSM group, NAC sensitivity was assessed using Semmes Weinstein monofilaments with a 5-point scale and compared with NAC sensitivity in a nonoperated control group. The SSM group comprised 25 women (50 SSMs) and the NSM group 20 women (39 NSMs). Median follow-up was 65 months in the SSM group compared with 27 months in the NSM group (P Breast-Q scores were favorable in the SSM group compared with the NSM group with trends for higher "satisfaction with breasts" (66.2 vs 56.6; P = 0.06) and "satisfaction with outcome" (76.1 vs 61.5; P = 0.09). Mean BIS score of 7.1/30 in the SSM group and 9.3/30 in the NSM group (P = 0.35). Adjusted for follow-up, there were no significant differences in Breast-Q scores, nor in BIS scores. Interestingly, satisfaction with the (reconstructed) NAC was similar after SSM and NSM. Nipple-areola complex sensitivity was lower in the NSM group (mean score, 1.9; 95% confidence interval, 1.5-2.3) compared with the control group (mean score, 4.7; 95% confidence interval, 4.6-4.9; P Breast-Q scores regarding satisfaction with breasts and overall outcome were in favor of the SSM group.

Therefore, immediate-delayed implantation can shorten the time of repair. OBJECTIVE:To evaluate the effect of implant repair after immediate-delayed implantation and application of guided bone regeneration technique in anterior maxila area. METHODS:Nineteen patients (28 teeth lost) with maxilary anterior tooth loss and labial one-waled bone defects were selected. Twenty-eight OSSTEM implants were implanted at 4 weeks after tooth extraction. Guided bone regeneration technique was applied concurrently in labial bone defect area. The secondary repair was

    Full Text Available Insulin-like growth factor I (IGF-I and its type I receptor (IGF-IR play significant roles in tumorigenesis and in immune response. Here, we wanted to know whether an RNA interference approach targeted to IGF-IR could be used for specific antitumor immunostimulation in a breast cancer model. For that, we evaluated short interfering RNA (siRNAs for inhibition of in vivo tumor growth and immunological stimulation in immunocompetent mice. We designed 2'-O-methyl-modified siRNAs to inhibit expression of IGF-IR in two murine breast cancer cell lines (EMT6, C4HD. Cell transfection of IGF-IR siRNAs decreased proliferation, diminished phosphorylation of downstream signaling pathway proteins, AKT and ERK, and caused a G0/G1 cell cycle block. The IGF-IR silencing also induced secretion of two proinflammatory cytokines, TNF- α and IFN-γ. When we transfected C4HD cells with siRNAs targeting IGF-IR, mammary tumor growth was strongly delayed in syngenic mice. Histology of developing tumors in mice grafted with IGF-IR siRNA treated C4HD cells revealed a low mitotic index, and infiltration of lymphocytes and polymorphonuclear neutrophils, suggesting activation of an antitumor immune response. When we used C4HD cells treated with siRNA as an immunogen, we observed an increase in delayed-type hypersensitivity and the presence of cytotoxic splenocytes against wild-type C4HD cells, indicative of evolving immune response. Our findings show that silencing IGF-IR using synthetic siRNA bearing 2'-O-methyl nucleotides may offer a new clinical approach for treatment of mammary tumors expressing IGF-IR. Interestingly, our work also suggests that crosstalk between IGF-I axis and antitumor immune response can mobilize proinflammatory cytokines.

    Objective To explore possible mechanism of delayed uveitis after intraocular lens implantation. Methods There were 320 paitnets (360 eyes) receiving intraocular lens implantation, and their delayed uveitis condition after operation were observed. Changes of circulating immune complexes (CIC) before and after treatment were in dynamic detection for analysis of pathogenesis for delayed uveitis. Results In 6 weeks after operation, there were 11 cases (11 eyes) with delayed uveitis, and the morbidity was 3.06%. After local and general corticosteroid hormone treatment, their vision recovery was good. CIC level in delayed uveitis group was obviously higher than that in non-delayed uveitis group (P<0.05). All the 11 cases (11 eyes) had acute delayed uveitis, there were 7 cases due to fatigue or excessive eye use after 2 weeks of operation, 2 cases due to disobedient of doctor order, 1 case due to high myopia, and 1 case due to diabetes mellitus. Conclusion Delayed uveitis after intraocular lens implantation is correlated with immune complex deposits of implantation. Morbidity of delayed uveitis can be reduced by postoperative rest, regular examination, long-term drug use, and blood glucose control. Timely and effective hormonotherapy can provide satisfactory effect in treating delayed uveitis.%目的:探讨人工晶状体植入术后并发迟发性葡萄膜炎的可能机制。方法320例(360眼)接受人工晶状体植入术的患者,观察患者手术后迟发性葡萄膜炎的发生情况,动态监测所有患者手术前和手术后的循环免疫复合物(CIC)水平变化情况,分析迟发性葡萄膜炎的发病诱因。结果术后6周内,11例(11眼)出现迟发性葡萄膜炎,发病率3.06%。经过局部及全身皮质类固醇激素治疗后,视力恢复情况良好。发生迟发性葡萄膜炎组患者的 CIC 水平明显高于未发生迟发性葡萄膜炎组患者(P<0.05),11例(11眼)出现迟发性葡萄膜炎患者均为突然发生,7例为术后2

    Although autologous tissue reconstruction is the best option for breast reconstruction, using implants is still a reliable and simple method, offering acceptable aesthetic results. Becker-type implants are permanent implants that offer a 1-stage reconstructive option. A retrospective study was carried out in our center reviewing the clinical reports of 237 patients, in whom a total of 314 Becker-type prostheses were implanted. Overall survival was calculated using a Kaplan-Meier estimate. Cox proportional hazard models were used to calculate adjusted hazard ratios. At the end of the study, 214 expanders (68.15%) presented no complications, 40 (12.47%) developed significant capsular contracture, in 27 (8.60%) infection occurred, 24 (7.64%) suffered minor complications, and 9 (2.87%) ruptured. The mean survival time of the expanders was 120.41 months (95% CI: 109.62, 131.19). Radiotherapy, chemotherapy, high Molecular Immunology Borstel, age, mastectomy performed previously to the implant, ductal carcinoma, advanced tumoral stage, experience of the surgeon, and Becker 35-type implants were significantly related to a high number of complications in relation to the survival of the implants. Cox regression analysis revealed that the main risk factors for the survival of expander implants included radiotherapy and surgeon experience. The complication hazard ratio or relative risk caused by these 2 factors was 1.976 and 1.680, respectively. One-stage reconstruction using Becker-type expanders is an appropriate, simple, and reliable option in delayed breast reconstruction in patients who have not received radiotherapy and as long as the procedure is carried out by surgeons skilled in the technique.

    Purpose: ZRBA1 is a combi-molecule designed to induce DNA alkylating lesions and to block epidermal growth factor receptor (EGFR) TK domain. Inasmuch as ZRBA1 downregulates the EGFR TK-mediated antisurvival signaling and induces DNA damage, we postulated that it might be a radiosensitizer. The aim of this study was to further investigate the potentiating effect of ZRBA1 in combination with radiation and to elucidate the possible mechanisms of interaction between these 2 treatment modalities. Methods and Materials: The triple negative human breast MDA-MB-468 cancer cell line and mouse mammary cancer 4T1 cell line were used in this study. Clonogenic assay, Western blot analysis, and DNA damage analysis were performed at multiple time points after treatment. To confirm our in vitro findings, in vivo tumor growth delay assay was performed. Results: Our results show that a combination of ZRBA1 and radiation increases the radiation sensitivity of both cell lines significantly with a dose enhancement factor of 1.56, induces significant numbers of DNA strand breaks, prolongs higher DNA damage up to 24 hours after treatment, and significantly increases tumor growth delay in a syngeneic mouse model. Conclusions: Our data suggest that the higher efficacy of this combination could be partially due to increased DNA damage and delayed DNA repair process and to the inhibition of EGFR. The encouraging results of this combination demonstrated a significant improvement in treatment efficiency and therefore could be applicable in early clinical trial settings.

    Objective: Investigate the benefit of functional multi-slice spiral computed tomography (f-MSCT) perfusion imaging in the non-invasive assessment of targeted anti-angiogenesis therapy on an implanted rabbit VX2 breast tumor model. Method: 69 female pure New Zealand white rabbits were randomly assigned to one of the 4 groups and received treatment accordingly: control (saline), Endostar, neoadjuvant chemotherapy (Cyclophosphamide, Epirubicin and 5-Fluorouracil, CEF), combination therapy (Endostar and CEF). After 2 weeks of treatment, f-MSCT perfusion scannings were performed for all rabbits and information about blood flow (BF), blood volume (BV), mean transit time (MTT) and surface permeability (SP) was collected. After perfusion imaging, tumor tissues were sampled for immunohistochemistry and the Western blot test of VEGF protein expression. Results: (1) The VEGF expression level, measured by immunohistochemistry and Western blot, decreased by treatment group (control > Endostar > CEF > combination therapy). The same was true for the mean BF, BV, MTT and PS, which decreased from the control group to the combination therapy group gradually. The mean MTT level increased in reverse order from the control to the combination therapy group. The difference between any 2 groups on these measures was statistically significant (P < 0.05). (2) There was moderate positive correlation between VEGF expression and BE, BV, or PS level (P < 0.05) and a negative correlation between VEGF expression and MTT level for all 4 groups (P < 0.05). Conclusion: Therefore, f-MSCT can be used as a non-invasive approach to evaluate the effect of anti-angiogenic therapy for implanted rabbit VX2 breast tumors.

    To appraise the feasibility of loading four implants with a pre-existing denture converted to a fixed dental prosthesis (FDP) on the day of implant surgery compared with waiting for 3- to 4-month healing. Patients with an edentulous, fully healed mandible were recruited in a faculty clinic to partake in a blinded two-arm parallel randomized controlled trial (RCT). The participants received four parallel intraforamina mandibular implants with a moderately rough titanium surface (Brånemark System Mk III or Mk IV TiUnite; Nobel Biocare AB, Göteborg, Sweden). The implants were loaded on the same day by converting the participants' pre-existing denture in the experimental group. The implants were placed using a one-stage surgery procedure, and the participants' pre-existing denture were soft-relined in the control group. For both groups, the permanent 10- to 12-unit FDP consisting of a type-3 cast precious alloy veneered with acrylic and artificial teeth was placed 3-4 months after implant surgery. All participants have been recalled annually for 5 years for appraisal of bone loss and registration of adverse events. Thirty-five of the original 42 participants (83%) returned for clinical and radiological examinations at the 5-year follow-up recall. No selective dropout or specific reasons for dropout was identified in the two study arms; leaving n = 17 (Intention-to-treat group, ITT) in the experimental group, alternatively n = 13 as per protocol group (PP), and n = 18 participants in the control group (ITT = PP). At study commencement, five of the participants assigned to the experimental group did not receive their planned intervention. In the control group, one implant failed to osseointegrate and another failed due to bone loss after 5 years. The crestal bone level changes over 5 years were identical in the experimental and control groups, that is, 1.2 mm (SD = 0.7). There were no differences between the two study arms with regard to incidence of biological and

    Positron emission tomography/computed tomography (PET/CT) imaging with fluorodeoxyglucose (FDG) have been used as a powerful fusion modality in nuclear medicine not only for detecting cancer but also for staging and therapy monitoring. Nevertheless, there are various causes of FDG uptake in normal and/or benign tissues. The purpose of present study was to investigate whether additional delayed imaging can improve the diagnosis to differentiate the rates of FDG uptake at axillary lymph nodes (ALN) between malignant and benign in breast cancer patients. 180 PET/CT images were obtained for 27 patients with ALN uptake. The patients who had radiotherapy and chemotherapy were excluded from the study. {sup 18}F-FDG PET/CT scan at 50 min (early phase) and 90 min (delayed phase) after {sup 18}F-FDG injection were included in this retrospective study. The staging of cancers was confirmed by final clinical according to radiologic follow-up and pathologic findings. The standardized uptake value (SUV) of ALN was measured at the Syngo Acquisition Workplace by Siemens. The 27 patients included 18 malignant and 9 ALN benign groups and the 18 malignant groups were classified into the 3 groups according to number of metastatic ALN in each patient. ALNs were categorized less than or equal 3 as N1, between 4 to 9 as N2 and more than 10 as N3 group. Results are expressed as the mean ± standard deviation (S.D.) and statistically analyzed by SPSS. As a result, Retention index (RI-SUV max) in metastasis was significantly higher than that in non-metastasis about 5 fold increased. On the other hand, RI-SUV max in N group tended to decrease gradually from N1 to N3. However, we could not prove significance statistically in malignant group with ANOVA. As a consequence, RI-SUV max was good indicator for differentiating ALN positive group from node negative group in breast cancer patients. These results show that dual-time-point scan appears to be useful in distinguishing malignant from benign.

    To determine the utility of {sup 18}F-FDG (FDG) PET/CT performed in an early and delayed phase during neoadjuvant chemotherapy in the prediction of lymph node histopathological response in patients with locally advanced breast cancer. FDG PET/CT studies performed in 76 patients (mean age 53 years) at baseline (PET-1), after the second course of chemotherapy (PET-2) and after the last course of chemotherapy (PET-3) were prospectively analysed. Inclusion criteria were lymph node involvement detected by PET/CT and non-sentinel node biopsy before or after the baseline PET/CT scan. Following the recommendations of the 12th International Breast Conference (St. Gallen), the patients were divided into five subgroups in relation to biological prognostic factors by immunohistochemistry. For diagnosis visual and semiquantitative analyses was performed. Absence of detectable lymph node uptake on the PET-2 or PET-3 scan with respect to the PET-1 scan was considered metabolic complete response (mCR). Lymph nodes were histopathologically classified according the lymph node regression grade and in response groups as pathological complete response (pCR) or not pCR (type A/D or B/C of the Smith grading system, respectively). ROC analysis was performed to determine a cut-off value of Δ% SUV1-2 and SUV1-3 for prediction of nodal status after chemotherapy. An association between mCR and pCR was found (Cohen's kappa analysis), and associations between phenotypes and metabolic behaviour and the final histopathological status were also found. Lymph node pCR was seen in 34 patients. The sensitivity, specificity, and positive and negative predictive values of PET-2 and PET-3 in establishing the final status of the axilla after chemotherapy were 52 %, 45 %, 50 % and 47 %, and 33 %, 84 %, 67 % and 56 %, respectively. No significant relationship was observed between mCR on PET-2 and PET-3 and pCR (p = 0.31 and 0.99, respectively). Lymph node metabolism on PET-1 was not able to predict

    Full Text Available Chromosome instability (CIN is associated with poor survival and therapeutic outcome in a number of malignancies. Despite this correlation, CIN can also lead to growth disadvantages. Here, we show that simultaneous overexpression of the mitotic checkpoint protein Mad2 with KrasG12D or Her2 in mammary glands of adult mice results in mitotic checkpoint overactivation and a delay in tumor onset. Time-lapse imaging of organotypic cultures and pathologic analysis prior to tumor establishment reveals error-prone mitosis, mitotic arrest, and cell death. Nonetheless, Mad2 expression persists and increases karyotype complexity in Kras tumors. Faced with the selective pressure of oncogene withdrawal, Mad2-positive tumors have a higher frequency of developing persistent subclones that avoid remission and continue to grow.

    Objectives To appraise the feasibility of loading four implants with a pre-existing denture converted to a fixed dental prosthesis (FDP) on the day of implant surgery compared with waiting for 3- to 4-month healing. Methods Patients with an edentulous, fully healed mandible were recruited in a faculty clinic to partake in a blinded two-arm parallel randomized controlled trial (RCT). The participants received four parallel intraforamina mandibular implants with a moderately rough titanium surface (Brånemark System Mk III or Mk IV TiUnite; Nobel Biocare AB, Göteborg, Sweden). The implants were loaded on the same day by converting the participants' pre-existing denture in the experimental group. The implants were placed using a one-stage surgery procedure, and the participants' pre-existing denture were soft-relined in the control group. For both groups, the permanent 10- to 12-unit FDP consisting of a type-3 cast precious alloy veneered with acrylic and artificial teeth was placed 3–4 months after implant surgery. All participants have been recalled annually for 5 years for appraisal of bone loss and registration of adverse events. Results Thirty-five of the original 42 participants (83%) returned for clinical and radiological examinations at the 5-year follow-up recall. No selective dropout or specific reasons for dropout was identified in the two study arms; leaving n = 17 (Intention-to-treat group, ITT) in the experimental group, alternatively n = 13 as per protocol group (PP), and n = 18 participants in the control group (ITT = PP). At study commencement, five of the participants assigned to the experimental group did not receive their planned intervention. In the control group, one implant failed to osseointegrate and another failed due to bone loss after 5 years. The crestal bone level changes over 5 years were identical in the experimental and control groups, that is, 1.2 mm (SD = 0.7). There were no differences between the two study arms

    Full Text Available Background  To date, various types of acellular dermal matrix (ADM have been developedfor clinical use. AlloDerm is the most familiar type of ADM to most surgeons in breastreconstruction. It is prepared by freeze-drying. CG CryoDerm is the first form of ADM thatrequires no drying process. Therefore,theoretically, it has a higher degree of preservation ofthedermalstructuresthan AlloDerm. We conducted thisstudy to compare the clinical course andpostoperative outcomes of patientswho underwent direct-to-implant breastreconstructionsusing AlloDermand thosewho did using CGCryoDerm.Methods  We performed a retrospective analysis ofthemedicalrecordsin a consecutive seriesof 50 patientswho underwent direct-to-implant breastreconstruction usingAlloDerm(n= 31or CryoDerm (n= 19. We then compared the clinical course and postoperative outcomes ofthe two groups based on the overall incidence of complications

    A 73-year-old woman had undergone mastectomy for left breast cancer. One year later, bone metastasis was detected. After 7 years, the patient experienced epigastric discomfort, and gastrointestinal endoscopy showed stenosis of the pylorus and enlarged gastric folds. Stomach cancer was suspected at first, but gastric metastasis of breast cancer was diagnosed on the basis of endoscopic reexamination and computed tomography(CT)images. The patient could not drink water, and therefore, gastrointestinal stenting was performed, which facilitated ingestion to some extent. However, at the same time, an elevated serum carcinoembryonic antigen(CEA)level and jaundice were observed. Therefore, biliary tract stenosis due to carcinomatous peritonitis was diagnosed. We attempted to treat the jaundice with endoscopic retrograde cholangiopancreatography( ERCP)or percutaneous transhepatic cholangiography(PTCD), but the treatment was not successful, and an increase in ascites was noted. Accordingly, gemcitabine was administered as systemic therapy. As a result, ascites decreased and jaundice improved. Patients with gastric metastasis of breast cancer have poor quality of life(QOL)because of difficulties in ingestion or vomiting, and poor prognoses, because of frequent concurrent carcinomatous peritonitis. We experienced a case of gastric metastasis and carcinomatous peritonitis, and were able to improve the patient's QOL by gastrointestinal stenting and gemcitabine administration.

    Purpose: To identify and analyze the appearance of calcifications and brachytherapy seeds on magnitude and phase MRI images and to investigate whether they can be distinguished from each other on corrected phase images for application to prostate and breast low dose rate (LDR) implant dosimetry. Methods: An agar-based gel phantom containing two LDR brachytherapy seeds (Advantage Pd-103, IsoAid, 0.8mm diameter, 4.5mm length) and two spherical calcifications (large: 7mm diameter and small: 4mm diameter) was constructed and imaged on a 3T Philips MR scanner using a 16-channel head coil and a susceptibility weighted imaging (SWI) sequence (2mm slices, 320mm FOV, TR/ TE= 26.5/5.3ms, 15 degree flip angle). The phase images were unwrapped and corrected using a 32×32, 2D Hanning high pass filter to remove background phase noise. Appearance of the seeds and calcifications was assessed visually and quantitatively using Osirix (http://www.osirix-viewer.com/). Results: As expected, calcifications and brachytherapy seeds appeared dark (hypointense) relative to the surrounding gel on the magnitude MRI images. The diameter of each seed without the surrounding artifact was measured to be 0.1 cm on the magnitude image, while diameters of 0.79 and 0.37 cm were measured for the larger and smaller calcifications, respectively. On the corrected phase images, the brachytherapy seeds and the calcifications appeared bright (hyperintense). The diameter of the seeds was larger on the phase images (0.17 cm) likely due to the dipole effect. Conclusion: MRI has the best soft tissue contrast for accurate organ delineation leading to most accurate implant dosimetry. This work demonstrated that phase images can potentially be useful in identifying brachytherapy seeds and calcifications in the prostate and breast due to their bright appearance, which helps in their visualization and quantification for accurate dosimetry using MR-only. Future work includes optimizing phase filters to best identify

    Full Text Available PURPOSE: To evaluate the effect of local nitroglycerin on the viable area of a prefabricated flap for vascular implant in rats, and to investigate the surgical delay procedure. METHODS: A femoral pedicle was implanted under the skin of the abdominal wall in forty Wistar rats. The animals were divided into four groups of ten: group 1 - without surgical delay procedure and local nitroglycerin; group 2 - with surgical delay procedure, but without local nitroglycerin; group 3 - without surgical delay procedure, but with local nitroglycerin; and group 4 - with simultaneous surgical delay procedure and local nitroglycerin. The percentages of the viable areas, in relation to the total flap, were calculated using AutoCAD R 14. RESULTS: The mean percentage value of the viable area was 8.9% in the group 1. 49.4% in the group 2; 8.4% in the group 3 and 1.1% in the group 4. There was significant difference between groups 1 and 2 (p=0.005, 1 and 4 (p=0.024, 2 and 3 (p=0.003, 2 and 4 (p=0.001. These results support the hypothesis that the closure of the arterial venous channels is responsible for the phenomenon of surgical delay procedure. CONCLUSION: Local nitroglycerin did not cause an increase in the prefabricated viable flap area by vascular implantation and decreased the viable flap area that underwent delay procedures.OBJETIVO: Avaliar o efeito da nitroglicerina tópica sobre a área viável de um modelo de retalho pré-fabricado por implante vascular em ratos e analisar o mecanismo de autonomização cirúrgica aplicada a retalhos pré-fabricados.

    Background Substantial complication rates after postmastectomy breast reconstruction (BR) in breast cancer patients have been reported. Few studies have reported on the resulting psychological distress (PD) and satisfaction with the aesthetic result in relation to postoperative complications after completion of implant or DIEP flap BR. The present study investigated whether women were able to recover from complication related distress in the long term. Methods PD was prospectively measured using questionnaires regarding anxiety, depression and cancer distress. Eligible patients completed questionnaires before BR (T0, n = 144), after one month (T1, n = 139) and after completion of BR, approximately 21 months after initial reconstructive surgery (T2, n = 119). Satisfaction with the aesthetic result was assessed 21 months after BR. Data concerning complications, subsequent additional surgery and total reconstruction failure up to T2 were collected from the medical records. Analyses were performed using multi-level regression analyses correcting for age. Results One or more complications occurred in 61 patients (42%) and 50 women required subsequent surgery (35%). In time, mean PD significantly declined towards baseline scores independent of complications. However, a total reconstruction failure (n = 10) was significantly associated with a large temporary increase in depression scores. After additional surgery due to complications patients were less satisfied with aesthetic outcome, although patient satisfaction was independent of PD. Conclusions PD outcomes generally declined to normal levels after completion of the entire BR course. Patients experiencing a total reconstruction failure reported more depression after this loss, but in the long term recovered to the same level as women without complications. These findings indicate that women generally can cope efficiently with these serious adverse events, even if they were less satisfied with the aesthetic result

    Purpose The use of multicatheter interstitial brachytherapy (MIB) for accelerated partial breast irradiation (APBI) in early breast cancer (EBC) patients outside the trial setting has increased. Hence, there is a need to critically evaluate implant quality. Moreover, there is a scarcity of reports using an open cavity technique. We report the dosimetric indices of open and closed cavity MIB techniques. Material and methods The dosimetric parameters of 60 EBC patients treated with MIB (open and closed cavity) who underwent three dimensional, computerized tomography (CT) based planning for APBI from November 2011 to July 2015 were evaluated. Coverage Index (CI), Dose Homogeneity Index (DHI), Conformity Index (COIN), Plan Quality Index (PQI), and Dose Non-uniformity Index (DNR) were assessed. Results Forty-one patients underwent open cavity and 19 patients underwent closed cavity placement of brachytherapy catheters. The median number of planes was 4 and median number of needles was 20. Median dose was 34 Gy with dose per fraction of 3.4 Gy, given twice a day, 6 hours apart. The D90 of the cavity and clinical target volume (CTV) were 105% and 89%, respectively. The median doses to the surgical clips were greater than 100%. The median CI of the cavity and CTV was 0.96 and 0.82, respectively. The DHI and COIN index of the CTV was 0.73 and 0.67. There were no significant differences in the dosimetric parameters based on whether the technique was done open or closed. Conclusions Critical evaluation of the dosimetric parameters of MIB-APBI is important for optimal results. While the open and closed techniques have similar dosimetry, our institutional preference is for an open technique which eases the procedure due to direct visualization of the tumor cavity.

    Purpose: To propose a novel framework for accurate model-based dose calculations using only MR images for LDR prostate and breast seed implant brachytherapy. Methods: Model-based dose calculation methodologies recommended by TG-186 require further knowledge about specific tissue composition, which is challenging with MRI. However, relying on MRI-only for implant dosimetry would reduce the soft tissue delineation uncertainty, costs, and uncertainties associated with multi-modality registration and fusion processes. We propose a novel framework to address this problem using quantitative MRI acquisitions and reconstruction techniques. The framework includes three steps: (1) Identify the locations of seeds(2) Identify the presence (or absence) of calcification(s)(3) Quantify the water and fat content in the underlying tissueSteps (1) and (2) consider the sources that limit patient dosimetry, particularly the inter-seed attenuation and the calcified regions; while step (3) targets the quantification of the tissue composition to consider the heterogeneities in the medium. Our preliminary work has shown that the seeds and the calcifications can be identified with MRI using both the magnitude and the phase images. By employing susceptibility-weighted imaging with specific post-processing techniques, the phase images can be further explored to distinguish the seeds from the calcifications. Absolute quantification of tissue, water, and fat content is feasible and was previously demonstrated in phantoms and in-vivo applications, particularly for brain diseases. The approach relies on the proportionality of the MR signal to the number of protons in an image volume. By employing appropriate correction algorithms for T1 - and T2*-related biases, B1 transmit and receive field inhomogeneities, absolute water/fat content can be determined. Results: By considering calcification and interseed attenuation, and through the knowledge of water and fat mass density, accurate patient

    Objective: The proper time to commence adjuvant chemotherapy after primary surgery for breast cancer is unknown. It is usually prescribed within 2-3 months after definitive surgery. The aim of this retrospective study was to assess the impact of adjuvant chemotherapy (CT) delay beyond 3 weeks ( 21 days) in premenopausal patients with ER-absent tumors being treated for early stages breast cancer on overall survival (OS) and disease-free survival (DFS). Methods: This retrospective study was conducted through revision of medical records of premenopausal patients diagnosed with early stage I-IIIA breast cancer and ER-absent tumors who received adjuvant CT after definitive surgery at the Department of Clinical Oncology, Ain-Shams University Hospitals. Results: Between 2005 and 2008, 105 patients were retrospectively analyzed and included. Patients were divided into 2 groups: Group A including 48 patients who started adjuvant CT < 21 days of surgery and group B which included 57 patients who had CT delay < 21 days. Both groups were matched demographically. Comparisons of overall survival, and disease-free survival between group A and group B patients all favored group A. At 5-year the OS rates were 87% and 73% for groups A and B respectively (P = 0.001), while DFS rates were 85% and 64% in groups A and B respectively (P = 0.001). Analysis of other prognostic factors (age, T, N, grade, HER2 status, surgery type, CT type, local radiotherapy received) were analyzed. Only nodal status predicted for worse DFS (P = 0.05) and OS (P = 0.006). Conclusion: Delay in initiating adjuvant chemotherapy for early stage breast cancer patients with ER-absent tumors was associated with a decrease in both OS and DFS rates.

    Monocyte chemoattractant protein 1 (MCP-1) has been implicated as a major modulator in the progression of mammary tumorigenesis, largely due to its ability to recruit macrophages to the tumor microenvironment. Macrophages are key mediators in the connection between inflammation and cancer progression and have been shown to play an important role in tumorigenesis. Thus, MCP-1 may be a potential therapeutic target in inflammatory and difficult-to-treat cancers such as triple negative breast cancer (TNBC). We examined the effect of MCP-1 depletion on mammary tumorigenesis in a model of TNBC. Tumor measurements were conducted weekly (until 22 weeks of age) and at sacrifice (23 weeks of age) in female C3(1)/SV40Tag and C3(1)/SV40Tag MCP-1 deficient mice to determine tumor numbers and tumorvolumes. Histopathological scoring was performed at 12 weeks of age and 23 weeks of age. Gene expression of macrophage markers and inflammatory mediators were measured in the mammary gland and tumor microenvironment at sacrifice. As expected, MCP-1 depletion resulted in decreased tumorigenesis, indicated by reduced primary tumor volume and multiplicity, and a delay in tumor progression represented by histopathological scoring (12 weeks of age). Deficiency in MCP-1 significantly downregulated expression of macrophage markers in the mammary gland (Mertk and CD64) and the tumor microenvironment (CD64), and also reduced expression of inflammatory cytokines in the mammary gland (TNFα and IL-1β) and the tumor microenvironment (IL-6). These data support the hypothesis that MCP-1 expression contributes to increased tumorigenesis in a model of TNBC via recruitment of macrophages and subsequent increase in inflammatory mediators.

    Breast reconstruction can be performed using a variety of techniques, most commonly categorized into an alloplastic approach or an autologous tissue method. Both strategies have certain risk factors that influence reconstructive outcomes and complication rates. In alloplastic breast reconstruction, surgical outcomes and complication rates are negatively impacted by radiation, smoking, increased body mass index (BMI), hypertension, and prior breast conserving therapy. Surgical factors such as the type of implant material, undergoing immediate breast reconstruction, and the use of fat grafting can improve patient satisfaction and aesthetic outcomes. In autologous breast reconstruction, radiation, increased BMI, certain previous abdominal surgery, smoking, and delayed reconstruction are associated with higher complication rates. Though a pedicled transverse rectus abdominis myocutaneous (TRAM) flap is the most common type of flap used for autologous breast reconstruction, pedicled TRAMs are more likely to be associated with fat necrosis than a free TRAM or deep inferior epigastric perforator (DIEP) flap. Fat grafting can also be used to improve aesthetic outcomes in autologous reconstruction. This article focuses on factors, both patient and surgical, that are predictors of complications and outcomes in breast reconstruction. PMID:26645003

    拔牙后牙槽嵴的高度、宽度及周围软组织的保存对于缺牙部位进行种植修复有着非常重要的意义.牙齿拔除后,拔牙窝内新生骨一般无法达到原牙槽嵴的水平,唇颊侧骨板受到的损害尤其严重,造成种植体植入时骨量不足.拔牙位点保存的目的是在拔牙窝内植入生物材料,有效地保存剩余牙槽嵴的高度、宽度以及相应软组织量,为随后的种植手术和修复提供足够的骨量和美学基础.本文报道1例拔牙位点保存延期种植即刻修复病例,经3年的临床观察,证实拔牙窝内植入人工骨粉,拉拢缝合,牙槽嵴保存良好,能满足后期种植牙即刻修复的美观与功能要求.%The site preservation of the alveolar ridge height,width and the surrounding soft tissue after tooth extraction has very important significance for the subsequent dental implantation.After tooth extraction,new bone in extraction sockets is generally unable to reach the original alveolar crest level. The labial or buccal bone plate is usually seriously damaged,resulting in the bone deficiency.Site preservation after tooth extraction can effectively save the residual alveolar ridge height,width and the corresponding soft tissue to provide sufficient bone and aesthetic foundation for subsequent implant surgery and restoration.The paper report one case of delayed dental implantation with immediate prosthesis after extraction socket site preservation.It was clinically confirmed the alveolar ridge was well preserved to meet the subsequent dental implantation and immediate restoration,by plugging artificial biomaterials in extraction socket and only sutureing the wound.

    Purpose: To investigate image-registration errors when using fiducial markers with a manual method and the point-based rigid-body registration (PRBR) algorithm in accelerated partial breast irradiation (APBI) patients, with accompanying fiducial deviations. Methods: Twenty-two consecutive patients were enrolled in a prospective trial examining 10-fraction APBI. Titanium clips were implanted intraoperatively around the seroma in all patients. For image-registration, the positions of the clips in daily kV x-ray images were matched to those in the planning digitally reconstructed radiographs. Fiducial and gravity registration errors (FREs and GREs, respectively), representing resulting misalignments of the edge and center of the target, respectively, were compared between the manual and algorithm-based methods. Results: In total, 218 fractions were evaluated. Although the mean FRE/GRE values for the manual and algorithm-based methods were within 3 mm (2.3/1.7 and 1.3/0.4 mm, respectively), the percentages of fractions where FRE/GRE exceeded 3 mm using the manual and algorithm-based methods were 18.8%/7.3% and 0%/0%, respectively. Manual registration resulted in 18.6% of patients with fractions of FRE/GRE exceeding 5 mm. The patients with larger clip deviation had significantly more fractions showing large FRE/GRE using manual registration. Conclusions: For image-registration using fiducial markers in APBI, the manual registration results in more fractions with considerable registration error due to loss of fiducial objectivity resulting from their deviation. The authors recommend the PRBR algorithm as a safe and effective strategy for accurate, image-guided registration and PTV margin reduction.

    We performed immediate breast reconstruction after nipple-sparing mastectomy or skin-sparing mastectomy and evaluated the reconstruction procedure, cosmesis, and complications. Among the 30 patients included in the study, 6 received latissimus dorsi flaps, 1 received a transverse rectus abdominis myocutaneous flap, 7 received deep inferior epigastric perforator flaps, 1 received an implant, and 15 received tissue expanders. In addition, the results were excellent in 25 patients, good in 3 patients, and poor in 2 patients. As the number of patients with breast cancer is increasing, the demand for breast reconstruction will increase. Therefore, it is essential to choose an appropriate method of breast reconstruction for each case.

    Breast augmentation surgery involving the use of implants has been one of the most popular plastic surgical procedures for decades. As the multi-million female population who received breast implants ages, the risk of cancer is increasing rapidly, therefore the incidence of malignant disease in association with breast implants will increase as well. Although there is no relationship between tumor development and implants, these cases require special considerations in diagnostics, therapy and follow-up methods. Appropriate multidisciplinary treatment of tumors in augmented breasts corresponding with modern oncoplastic principles can only be accomplished based on adequate oncological, breast and plastic surgical knowledge. Supposing a possible increase of this condition in Hungary, too, authors provide a wide review of the literature on the special oncological and esthetic considerations, for the first time in Hungarian language.

    Full Text Available OBJECTIVES: This study aims to compare breast cancer screening (BCS and cervical cancer screening (CCS practices of French women born to French parents with those of immigrants and nationals born to immigrants, taking their socioeconomic status into account. METHODS: The study is based on data collected in 2010 in the Paris metropolitan area among a representative sample of 3000 French-speaking adults. For women with no history of breast or cervical cancer, multivariate logistic regressions and structural equation models were used to investigate the factors associated with never having undergone BCS or CCS. RESULTS: We confirmed the existence of a strong gradient, with respect to migration origin, for delaying or never having undergone BCS or CCS. Thus, being a foreign immigrant or being French of immigrant parentage were risk factors for delayed and no lifetime screening. Interestingly, we found that this gradient persisted (at least partially after adjusting for the women's socioeconomic characteristics. Only the level of income seemed to play a mediating role, but only partially. We observed differences between BCS and CCS which suggest that organized CCS could be effective in reducing socioeconomic and/or ethnic inequities. CONCLUSION: Socioeconomic status partially explained the screening nonparticipation on the part of French women of immigrant origin and foreign immigrants. This was more so the case with CCS than with BCS, which suggests that organized prevention programs might reduce social inequalities.

    Full Text Available The aim of this study is to determine if fluorescence-guided surgery (FGS can eradicate human fibrosarcoma growing in the retroperitoneum of nude mice. One week after retroperitoneal implantation of human HT1080 fibrosarcoma cells, expressing green fluorescent protein (GFP (HT-1080-GFP, in nude mice, bright-light surgery (BLS was performed on all tumor-bearing mice (n = 22. After BLS, mice were randomized into 2 treatment groups; BLS-only (n = 11 or the combination of BLS + FGS (n = 11. The residual tumors remaining after BLS were resected with FGS using a hand-held portable imaging system under fluorescence navigation. The average residual tumor area after BLS + FGS was significantly smaller than after BLS-only (0.4 ± 0.4 mm(2 and 10.5 ± 2.4 mm(2, respectively; p = 0.006. Five weeks after surgery, the fluorescent-tumor areas of BLS- and BLS + FGS-treated mice were 379 ± 147 mm(2 and 11.7 ± 6.9 mm(2, respectively, indicating that FGS greatly inhibited tumor recurrence compared to BLS. The combination of BLS + FGS significantly decreased fibrosarcoma recurrence compared to BLS-only treated mice (p < 0.001. Mice treated with BLS+FGS had a significantly higher disease-free survival rate than mice treated with BLS-only at five weeks after surgery. These results suggest that combination of BLS + FGS significantly reduced the residual fibrosarcoma volume after BLS and improved disease-free survival.

    BACKGROUND:Numerous studies have demonstrated that the use of periodontal tissue-guided regeneration technique significantly elevated success rate of immediate technical planting. No significant difference is detected as compared with the delayed planting success rate in the clinic. OBJECTIVE: To compare the clinical effects of immediate implant and delayed implant in the restoration of anterior teeth. METHODS:A total of 100 cases with former dental implants, who had 160 diseased teeth, were enroled in this study. They were divided into experimental and control groups according to the principle of random pairing. In the experimental group, the implant was put into the extraction sockets after minimaly invasive tooth extraction with the use of periodontal guided tissue regeneration technique. In the control group, at 3 months after minimaly invasive tooth extraction, implant was implanted in the sockets. Delayed planting repair of denture in the missing teeth area was performed with the use of periodontal guided tissue regeneration technique. Crown restoration was conducted in both groups at 3 months after implantation. Aesthetics, periodontal pocket depth and implant success rate were compared after repair in both groups. RESULTS AND CONCLUSION: Gingival esthetics score was better at 1, 3, 6 and 12 months after repair in the experimental group than in the control group (P 0.05). Above findings confirmed that aesthetic effect, treatment cycle, and the health of periodontal tissue were better in the immediate implanting group than in the delayed implanting group. However, no significant difference in success rate was detected between immediate implanting and delayed implanting groups.%背景:大量研究表明,牙周组织引导再生技术的使用显著提高了即刻种植技术的成功率,甚至在临床上与延期种植成功率无明显差别。目的:比较种植体即刻种植和延期种植修复前牙的临床效果。方法:选

    The use of autologous tissue transfer for breast augmentation is an alternative to using foreign implant materials. The benefits of this method are the removal of unwanted fat from other body parts, no risk of implant rupture, and the same feel as real breast tissue. However, sometimes there is a dilemma about whether or not to biopsy for calcifications or masses detected after the procedure is completed. The purpose of this study is to illustrate the procedures of breast augmentation with autologous tissues, the imaging features of various complications, and the role of imaging in the diagnosis and management of complications and hidden breast diseases.

El diagnóstico y el tratamiento fueron más rápidos en mujeres con mayor nivel educativo, afiliadas al régimen especial de salud, en el estrato socioeconómico más alto y cuando consultaron por tamización. CONCLUSION: Las demoras en la atención son excesivas. Hay una clara inequidad y se requieren intervenciones para brindar mayor oportunidad, particularmente para el diagnóstico.OBJECTIVE: Establish provider delay for breast cancer and related factors. MATERIAL AND METHODS: 1 106 women with breast cancer were approached in health care institutions of Bogota, Colombia. According to the history of first consultation, we established diagnostic and treatment incidence rates, which were compared for different variables. A Cox hazard model was established. RESULTS: Median time from first consultation to diagnosis and start of treatment were 91 days (CI95%:82-97 days and 137 days (CI95%:127-147 days respectively. Diagnosis and treatment were faster in women with higher educational level, affiliated to the "special" social security, with better socioeconomic conditions and in screening-detected breast cancers. CONCLUSION: Provider delay is excessive. There are clear inequities in access to services and a need of reducing the waiting times for women with a suspicion of breast cancer.

    To determine the effectiveness of a statewide telephone service in identifying low-income women at risk for hereditary breast and ovarian cancer and referring them to free genetic counseling. From June 2010 through August 2011, eligible callers to California's toll-free breast and cervical cancer telephone service were screened for their family histories of breast and ovarian cancer. High-risk women were identified and called for a baseline survey and randomization to an immediate offer of genetic counseling or a mailed brochure on how to obtain counseling. Clinic records were used to assess receipt of genetic counseling after 2 months. Among 1212 eligible callers, 709 (58.5%) agreed to answer family history questions; 102 (14%) were at high risk (25% Hispanic, 46% White, 10% Black, 16% Asian, 3% of other racial/ethnic backgrounds). Of the high-risk women offered an immediate appointment, 39% received counseling during the intervention period, as compared with 4.5% of those receiving the brochure. A public health approach to the rare but serious risk of hereditary breast and ovarian cancer can be successful when integrated into the efforts of existing safety net organizations.

    The aim of this study was to review one-stage breast reconstruction techniques performed in elderly patients at our institution to identify the criteria of selection of each in terms of outcomes and quality of life. Patients older than 65 years who underwent one-stage breast reconstruction between January 2004 and July 2014 at our hospital were included. Patients and procedure-related data were collected from the medical records. In particular, patient's age, comorbidities and related ASA physical status, type of one-stage breast reconstruction technique, and criteria of selection were analyzed. Outcomes and results were also evaluated in terms of quality of life using the EORTC QLQ-C30 and -BR23 questionnaires 1 year after surgery. A total of 840 women underwent breast reconstruction, of whom 138 elderly women received one-stage breast reconstruction. There were 118 cases (85.5%) of monolateral reconstructions and 20 cases (14.5%) of bilateral reconstructions, resulting in 138 breast reconstructions. These were performed with permanent inflatable expanders in the sub-muscular position (Group A, n= 50), with acellular dermal matrix and partial sub-muscular anatomic implant (Group B, n= 50), and with Braxon® acellular dermal matrix and anatomic implant with muscle-sparing technique (Group C, n= 38). The EORTC questionnaires showed the best results in Group C regarding the quality of life. The elderly population is rapidly increasing, and 50% of all breast cancers occur in women older than 65 years; among them, only 2% undergo breast reconstruction. A major aspect of breast cancer treatment and subsequent quality of life is the opportunity for a post-mastectomy reconstructive surgery. As survival rates are improving, a larger proportion of patients live with the long-term consequences of their treatment, and breast reconstruction ensures a better quality of life. To increase the reconstruction rates, surgery should be one-stage, less invasive as possible, allowing

    Delayed fission is a nuclear decay process that couples {beta} decay and fission. In the delayed fission process, a parent nucleus undergoes {beta} decay and thereby populates excited states in the daughter. If these states are of energies comparable to or greater than the fission barrier of the daughter, then fission may compete with other decay modes of the excited states in the daughter. In this paper, mechanism and some experiments of the delayed fission will be discussed. (author)

  16. Teenagers and cosmetic surgery: focus on breast augmentation and liposuction.

    Science.gov (United States)

    Zuckerman, Diana; Abraham, Anisha

    2008-10-01

    Two of the most popular and controversial cosmetic procedures for adolescents are liposuction and breast implants. In this review article, the procedures are discussed. In addition, the physiological and psychological reasons to delay these procedures, including concerns about body dysmorphic disorder and research findings regarding changes in teenagers' body image as they mature, are described. The lack of persuasive empirical research on the mental health benefits of plastic surgery for teenagers is highlighted. Finally, the long-term financial and health implications of implanted medical devices with a limited lifespan are presented. Adolescent medicine providers need to be involved in improving informed decision making for these procedures, aware of the absence of data on the health and mental health risks and benefits of these surgeries for teenagers, and understand the limitations on teenagers' abilities to evaluate risks.

    Full Text Available Abstract Background Skin Sparing Mastectomy (SSM and immediate breast reconstruction has become increasingly popular as an effective treatment for patients with breast carcinoma. The aim of this study was to evaluate the clinical outcome of skin sparing mastectomy in early breast cancer at a single population-based institution. Methods Records of ninety-five consecutive patients with operable breast cancer who had skin-sparing mastectomy and immediate breast reconstructions between 1995 and 2003 were reviewed. Patient and tumor characteristic, type of reconstruction, postoperative complications, aesthetic results and incidence of recurrence were analyzed. Results Mean age of the patients was 51.6(range 33–72 years. The AJCC pathologic stages were 0 (n = 51, 53.7%, I (n = 20, 21.1%, and II (n = 2, 2.1%. Twenty of the patients had recurrent disease (21.1%. The immediate breast reconstructions were performed with autologus tissue including latissimus dorsi musculocutaneous flap in 63 (66.3% patients and transverse rectus abdominis myocutaneous (TRAM flap in 4 (4.2% patients. Implants were used in 28 (29.4% patients. The average hospital stay was 7.7 days. Flap complication occurred in seven (10.4% patients resulting in four (6% re-operations and there were no delay in accomplishing postoperative adjuvant therapy. At a median follow-up of 69 months (range 48 to 144, local recurrence was seen in one patient (1.1% and systemic recurrence was seen in two patients (2.1%. Conclusion Skin sparing mastectomy and immediate breast reconstruction for early breast cancer is associated with low morbidity and low rate of local recurrence.

    Medical treatment for breast cancer is associated with substantial toxicity and patient burden. There is less known about the impact of surgical complications. Understanding this impact could provide important information for patients when they are considering surgical options. Between 2008 and 2009, the UK National Mastectomy and Breast Reconstruction Audit recorded surgical complications for a prospective cohort of 17,844 women treated for breast cancer at 270 hospitals; 6405 of these women were surveyed about their quality of life 18 months after surgery. Breast appearance, emotional well-being, and physical well-being were quantified on 0- to 100-point scales. Linear multiple regression models, controlling for a range of baseline prognostic factors, were used to compare the scores of patients who had complications with the scores of those who did not. The overall complication rate was 10.2%. Complications were associated with little or no impairment in women undergoing mastectomy without reconstruction or with delayed reconstruction. The association was much larger for flap-related complications suffered during immediate reconstruction. The breast-appearance scores (adjusted mean difference, -23.8; 95% confidence interval [CI], -31.0 to -16.6) and emotional well-being scores (adjusted mean difference, -14.0; 95% CI, -22.0 to -6.0) of these patients were much lower than those of any other patient group. Implant-related complications were not associated with a lower quality of life in any surgical group. There is a strong case for prospectively collecting flap-complication rates at the surgeon and surgical unit level and for allowing patients to access these data when they make choices about their breast cancer surgery.

    2012-09-01

    BACKGROUND: Silicone gel-containing breast implants have been widely used for aesthetic and reconstructive mammoplasty. The development of a periprosthetic capsule is considered a local reparative process against the breast implant in which a variety of inflammatory cells may appear. Nevertheless, only few reports have evaluated the immunophenotypes of those inflammatory cells. Herein, we aim to provide more information in this regard evaluating 40 patients with breast implants. METHODS: We studied the immunophenotype of the inflammatory cells of capsular implants using antibodies against lymphocytes (CD3, CD4, CD8, CD20, CD45, and CD30) and histiocytes (CD68). Percentages of CD3 and CD20 positive cells were compared using the unpaired Student's t test. Fisher's test was also used to compare Baker grades by implant type, implant profile, and location and the presence of inflammatory cells by implant type. RESULTS: The associations between Baker grades and implant type and location were statistically nonsignificant (p = 0.42 in both cases). However, the use of low profile implants was significantly associated (p = 0.002) with a higher proportion of Baker grades 3 and 4. We found evidence of inflammation in 92.5 % of all implant capsules, with a statistically significant (p = 0.036) higher proportion in textured breast implants. T cells predominated over B cells. Textured implants elicited a more marked response to T cells than smooth implants, with a similar proportion of helper and cytotoxic T cells. Textured implants showed statistically significant higher percentages of CD3 positive cells than smooth implants. Percentages of CD20 positive cells were similar in textured and smooth implants. CONCLUSIONS: These results suggest that textured breast implants might induce a stronger local T cell immune response. Our findings could shed some light to understand the association of silicone breast implants and some cases of anaplastic large cell lymphomas

    2013-01-01

    Full Text Available Background. Most women with breast cancer today can be managed with breast conservation; however, some women still require mastectomy for treatment of their disease. Skin-sparing mastectomy (SSM with immediate reconstruction has emerged as a favorable option for many of these patients. The authors combined the SSM technique with the preservation of a small part of the areola with immediate nipple together with with breast reconstruction. Methods. In an 8-year-period 155 female patients (age: 20–52 years old; mean age: 37.5 years with extensive ductal intraepithelial neoplasia (DIN or invasive breast cancer were treated with areola skin sparing mastectomy with immediate nipple and breast reconstruction. Patients were followed up prospectively by the breast surgeon, the plastic surgeon, and the oncologist for complications and recurrence. Results. After treatment, only 2 cases (1.29% had a local recurrence. 8 out of 155 (5.5% patients developed early complications (infections, seroma, haematoma, and 5 out of 155 patients (3.22% developed delayed complications (implant rotation, aestethic deterioration in the post operative time period. The final aesthetic outcome was judged as positive in 150 out of 155 patients (96.78%. Conclusion. In our experience, immediate nipple reconstruction after skin-sparing mastectomy is a technically feasible procedure which can give excellent cosmetic results.

    The optimum sequencing of breast reconstruction (BR) in patients receiving postmastectomy radiation therapy (PMRT) is controversial. A comprehensive search of published studies that examined postoperative morbidity following immediate or delayed BR with combined radiotherapy was performed. Medical (MEDLINE & EMBASE) databases were searched and cross-referenced for appropriate studies where morbidity following BR was the primary outcome measured. A total of 1,105 patients were identified from 11 appropriately selected studies. Patients undergoing PMRT and BR are more likely to suffer morbidity compared with patients not receiving PMRT (OR = 4.2; 95% CI, 2.4-7.2 [no PMRT vs. PMRT]). Reconstruction technique was also examined with outcome when PMRT was delivered after BR, and this demonstrated that autologous reconstruction is associated with less morbidity in this setting (OR = 0.21; 95% CI, 0.1-0.4 [autologous vs. implant-based]). Delaying BR until after PMRT had no significant effect on outcome (OR = 0.87; 95% CI, 0.47-1.62 [delayed vs. immediate]). PMRT has a detrimental effect on BR outcome. These results suggest that where immediate reconstruction is undertaken with the necessity of PMRT, an autologous flap results in less morbidity when compared with implant-based reconstruction.

    Full Text Available Implantable devices such as cardiac pacemakers, drug-delivery systems, and defibrillators have had a tremendous impact on the quality of live for many disabled people. To date, many devices have been developed for implantation into various parts of the human body. In this paper, we focus on devices implanted in the head. In particular, we describe the technologies necessary to create implantable microimagers. Design, fabrication, and implementation issues are discussed vis-à-vis two examples of implantable microimagers; the retinal prosthesis and in vivo neuro-microimager. Testing of these devices in animals verify the use of the microimagers in the implanted state. We believe that further advancement of these devices will lead to the development of a new method for medical and scientific applications.

    Proton induced X-ray emission was used for a multi-element analysis of three biomaterials implanted in ovine thighbone: one tri-tricalcic phosphate and two calcium carbonates with different percentages of porosity. The proton PIXE analysis method allowed the simultaneous quantification of several elements to get profiles of concentrations versus implantation delay. We focused on calcium and phosphorous which were major elements of the bony matrix and strontium, a trace element characteristic of the mineralization of the implants. Concentrations of calcium (constitutive of CaCO{sub 3} and TCP) and phosphorous (constitutive of TCP) were known and differed from the bony matrix concentrations. The analysis of each sample for various times after implantation (1, 3, 6 and 12 months) by PIXE permitted to observe the evolution of the concentration of Ca, P and Sr in the implant area and at the interface implant/bone and to compare the different biomaterials implanted.

    Objective To compare the therapy efficiency of immediate implanting breast reconstruction after skin sparing mastectomy and modified radical mastectomy in breast cancer. Methods The data of 530 female patients with early of stage 0 to Ⅲ a breast cancer was retrospectively analyzed, from January 2004 to Decembet 2008. Among the patients,91 patients operated with skin sparing mastectomy and immediate implanting breast reconstruction ( Group of immediate implanting reconstruction), and 439 patients were with modified radical mastectomy (Group of modified radical mastectomy ). By comparing complications, local recurrence, distant metastases and mortality rates between the two groups, the research was done to evaluate the therapy efficiency. Results In the group of immediate implanting reconstruction,84 patients completed follow-up with the median follow-up time of 35 months ( 14-72 months) while the local recurring rate was 2. 4%, distant metastasis rate was 8. 3% and mortality rate was 6. 0%. In the group of modified radical mastectomy, 398 patients completed follow-up with the median follow-up time of 36 months ( 12-74 months) while the local recurring rate was 3.3%, distant metastasis rate was 9. 5% and mortality rate was 6. 5%. Therefore there was no obvious statistic difference between the two groups in local recurring rate, distant metastasis rate and mortality rate (P > 0. 05 ). Evaluation of aesthetic results was done in the 84 patients after immediate implanting reconstruction for 12 months which was 93% as good or excellent by surgeons while 87% by patients. Surgeons and patients were both satisfied with the breast appearance. Conclusions For patients with early stage breast cancer, combining standard postoperative therapy, skin sparing mastectomy and immediate implanting reconstruction could achieve the same effect as the traditional modified radical mastectomy, while reconstruction would bring about better appearance and higher quality of life.%目的

    This study aimed to evaluate the influence of the type of prosthetic abutment associated to different implant connection on bone biomechanical behavior of immediately and delayed loaded implants. Computed tomography-based finite element models comprising a mandible with a single molar implant were created with different types of prosthetic abutment (UCLA or conical), implant connection (external hexagon, EH or internal hexagon, IH), and occlusal loading (axial or oblique), for both immediately and delayed loaded implants. Analysis of variance at 95%CI was used to evaluate the peak maximum principal stress and strain in bone after applying a 100 N occlusal load. The results showed that the type of prosthetic abutment influences bone stress/strain in only immediately loaded implants. Attachment of conical abutments to IH implants exhibited the best biomechanical behavior, with optimal distribution and dissipation of the load in peri-implant bone.

    The purpose of this study was to determine the dose to the contralateral breast during accelerated partial breast irradiation (APBI) and to compare it to external beam-published values. Thermoluminescent dosimeter (TLD) packets were used to measure the dose to the most medial aspect of the contralateral breast during APBI simulation, daily quality assurance (QA), and treatment. All patients in this study were treated with a single-entry, multicatheter device for 10 fractions to a total dose of 34 Gy. A mark was placed on the patient's skin on the medial aspect of the opposite breast. Three TLD packets were taped to this mark during the pretreatment simulation. Simulations consisted of an AP and Lateral scout and a limited axial scan encompassing the lumpectomy cavity (miniscan), if rotation was a concern. After the simulation the TLD packets were removed and the patients were moved to the high-dose-rate (HDR) vault where three new TLD packets were taped onto the patients at the skin mark. Treatment was administered with a Nucletron HDR afterloader using Iridium-192 as the treatment source. Post-treatment, TLDs were read (along with the simulation and QA TLD and a set of standards exposed to a known dose of 6 MV photons). Measurements indicate an average total dose to the contralateral breast of 70 cGy for outer quadrant implants and 181 cGy for inner quadrant implants. Compared to external beam breast tangents, these results point to less dose being delivered to the contralateral breast when using APBI.

    Cho, So Hyun; Park, Sung Hee

    2013-11-01

    The aim of this article is to review benign breast lesions that can mimic carcinoma on sonography. Cases of benign lesions mimicking carcinoma on sonography were collected among lesions that were initially assessed as suspicious on sonography according to the American College of Radiology Breast Imaging Reporting and Data System category. Sonographically guided core needle biopsy was performed, and the pathologic types were confirmed to be benign. Cases of benign lesions mimicking carcinoma on sonography were shown to include fat necrosis, diabetic mastopathy, fibrocystic changes, sclerosing adenosis, ruptured inflammatory cysts, inflammatory abscesses, granulomatous mastitis, fibroadenomas, fibroadenomatous mastopathy, and apocrine metaplasia. Benign breast lesions may present with malignant features on imaging. A clear understanding of the range of appearances of benign breast lesions that mimic malignancy is important in radiologic-pathologic correlation to ensure that benign results are accepted when concordant with imaging and clinical features but, when discordant, there is no delay in further evaluation up to and including excisional biopsy.

    Purpose: Breast cancer patients with bilateral implant reconstructions who require postmastectomy radiotherapy can pose unique treatment planning challenges. The use of VMAT may provide advantages over conventional tangent or multi-beam IMRT techniques. Moreover, daily setup uncertainly of the arm position, however, could have significant impact on accurate dose delivery. This study compares the plan qualities between non-AA and AA VMAT techniques. Methods: Three breast cancer patients receiving left chest wall and regional nodal irradiation with bilateral implant reconstructions were studied. PTV included chest wall and IMNs (PTV-CW), and supraclavicular and axillary lymph nodes (PTV-SCV). For each patient, one non-AA VMAT plan (VMAT-S) with 4 partial arcs encompassing the ipsilateral arm and three AA VMAT plans where no arcs were entering or existing through the ipsilateral arm were generated. VMAT-AA1 uses 2 arcs for PTV-CW and 2 arcs for PTV-SCV. VMAT-AA2 used two static fields for PTV-SCV with 2 arcs for PTV-CW. VMAT-AA3 used 2 narrow arcs for PTV-CW and 2 long arcs for all PTVs. Prescription dose (PD) was 50 Gy (25 fractions). All plans were normalized to have 95% of PD to 95 % of PTV. PTV dose inhomogeneity and dose to the heart, left lung, right thyroid dose and left humerus were evaluated. Results: For VMAT-S, VMAT-AA1, VMAT-AA2 and VMAT-AA3, respectively, the average and standard deviation (in Gy unless specified otherwise) of PTV D05 are 54.7±0.9, 55.9±0.4, 56.7±0.7 and 55.7±0.4; mean Heart dose: 7.1±0.7, 7.2±0.8, 7.3±0.9 and 6.9±1.0; left lung V20Gy (in %): 28.1±1.0, 28.8+2.2, 32.2±4.1 and 27.8±2.0; mean right thyroid dose: 8.1±0.6, 5.1±2.1, 2.1±0.4 and 5.0±2.0; mean left humerus dose: 20.0±4.4,15.6±4.4, 15.2±8.2 and 15.3±4.6. Conclusion: AA VMAT can produce acceptable clinical plans while eliminating dosimetric impact related to arm setup uncertainty. These data require validation in larger planning studies prior to routine clinical

    A breast cancer diagnosis imposes significant emotional and psychological duress. The purpose of this study is to assess the baseline quality of life (QOL) of immediate, delayed, and secondary breast reconstruction patients, comparing these results with QOL in women seeking plastic surgery for cosmetic breast, and non-breast procedures. From 2012 through 2013, immediate (group 1), delayed (group 2), and secondary (Group 3) reconstruction patients, aesthetic breast (group 4) and non-breast plastic surgery patients (group 5) answered Breast-Q questionnaires. Groups 1, 2, 3, 4, and 5 answered 141, 12, 23, 72 and 160 preoperative questionnaires respectively. There was no difference (p = NS) in breast satisfaction, psychosocial well-being, physical well-being-chest, and sexual well-being between groups 1 and 5. Group 1 had higher satisfaction with breast (p breasts (p breasts, psychosocial, and sexual well-being, compared to groups 2 and 3.

    Full Text Available Breast reconstruction after breast cancer surgery represents a positive step in restoring a women’s idea of self by reestablishing her feminine features and confidence, thus improving essential aesthetic and emotional aspects. Regarded as the cornerstone in breast cancer management, the surgical treatment has come a long way since 1884 when W.S. Halsted performed the first radical mastectomy- a disfiguring procedure which was conducted until the late 70s when owing to contemporary advancements it was surpassed by modified radical mastectomies and other far less invasive approaches. Either performed in an immediate or a delayed fashion breast reconstruction can be achieved not only through alloplastic procedures using expander/ implant prosthesis but also through autologous tissue transfers wisely harvested from different parts of the body or through methods that combine the two. When planning a breast reconstruction, after the oncologist formally rules out any form of residual cancer, one must take into consideration several critical factors that will eventually condition the technique election process for example the possible local or systemic adjuvant therapy. Although a “one size fits all” breast reconstruction procedure has yet to prevail, the extensive volume of published literature regarding this matter enables a well-experienced plastic surgeon to proceed with careful procedural selection allowing for the best possible results.

    The development of autoimmunity and/or autoimmune diseases is multifactorial. Vitamin D is one of the factors that might play a role. We postulated that both the presence of adjuvants and insufficient levels of vitamin D may result in the development of autoimmunity in patients with autoimmune/inflammatory syndrome induced by adjuvants (ASIA) in relation to silicone implant incompatibility. We measured vitamin D levels in 135 patients with ASIA in relation to silicone implant incompatibility and related findings to the presence of autoantibodies that are commonly used to diagnose systemic autoimmune diseases. Furthermore, we systematically reviewed the literature regarding vitamin D deficiency as a risk factor for the development of autoantibodies. Vitamin D measurements were available for analysis in 131 of 135 patients with ASIA in relation to SIIS. Twenty-three patients (18%) tested positive for autoantibodies, from which 18 patients (78%) had either a vitamin D deficiency or insufficiency (median vitamin D level 60.5 mmol/L), whereas five patients (22%) had sufficient vitamin D levels. The risk to develop autoantibodies was significantly increased in vitamin D deficient and/or insufficient patients [RR 3.14; 95% CI, 1.24-7.95; p = 0.009]. Reviewed literature suggested an association between vitamin D levels and the presence and/or titer levels of autoantibodies in different autoimmune diseases. From our current study and from our review of the literature, we conclude that vitamin D deficiency is related to the presence of autoantibodies. Whether vitamin D supplementation results in a decrease of autoimmunity needs to be studied prospectively.

    Breast cancer is the most common malignant tumor-affecting women during the child bearing period. With the rising trend in delaying pregnancy later in life, the issue of subsequent pregnancy and lactation following breast cancer diagnosis has been more frequently encountered. In this context, data is scarce particularly those addressing the issue of lactation. In this review, we discussed different endocrinal, clinical and biological aspects dealing with breast-feeding after breast cancer in an attempt to determine how safe and feasible this approach is.

Methods 28 cases with 56 breasts were included in this study, and the mammography, high-frequency ultrasound and MRI findings and its diagnostic value for silicone breast implant rupture were analyzed. Results The mammography can't show the integrity of the silicone breast implant(0%,0/56), and ultrasound and MRI can show it(100%,56/56). Both mammography, ultrasound and MRI can diagnose extracapsular rupture(7.1%,4/56). Mammography can't detect intracapsular rupture (0%,0/56),and MRI(32.1%,18/56)is better than ultrasound(21.4%,12/56)in detection of intracapsular rupture(P=0.031). Conclusion In detecting silicone breast implant rupture, mammography is a satisfied way, ultrasound is an economic and efficient way, and MRI is the most ideal way and it should be the first choice if the economy allowed.

  6. Immediate placement of endosseous implants into the extraction sockets

    Full Text Available Implant by definition "means any object or material, such as an alloplastic substance or other tissue, which is partial or completely inserted into the body for therapeutic, diagnostic, prosthetic, or experimental purpose." The placement of a dental implant in an extraction socket at the time of extraction or explantation is known as immediate implant placement whereas delayed placement of implant signifies the implant placement in edentulous areas where healing has completed with new bone formation after the loss of tooth/teeth. Recent idea goes by "why late when it can be done immediately." There are several advantages of immediate placement of implants, and lots of studies have been done. In this article, the advantages and disadvantages of immediate versus delayed placement of implants have been reviewed.

    Implantable contraception has been extensively used worldwide. Implants are one of the most effective and reversible methods of contraception available. These devices may be particularly appropriate for certain populations of women, including women who cannot use estrogen-containing contraception. Implants are safe for use by women with many chronic medical problems. The newest implant, Implanon (Organon International, Oss, The Netherlands), is the only device currently available in the United States and was approved in 2006. It is registered for 3 years of pregnancy prevention. Contraceptive implants have failure rates similar to tubal ligation, and yet they are readily reversible with a return to fertility within days of removal. Moreover, these contraceptive devices can be safely placed in the immediate postpartum period, ensuring good contraceptive coverage for women who may be at risk for an unintended pregnancy. Irregular bleeding is a common side effect for all progestin-only contraceptive implants. Preinsertion counseling should address possible side effects, and treatment may be offered to women who experience prolonged or frequent bleeding. Thieme Medical Publishers.

    Striae distensae or stretch marks after breast augmentation are a rare complication. To date, 10 cases have been published. In seven of these cases, the implant was placed in a subglandular position and in the other three cases, placement was submuscular. Two cases of stretch marks in two young nulliparous women who underwent subfacial breast augmentation are presented. To the best of the authors' knowledge, this is the first report of striae distensae after subfascial breast augmentation.

    Decision-making for women requiring reconstruction and post-mastectomy radiotherapy (PMRT) includes oncological safety, cosmesis, patient choice, potential delay/interference with adjuvant treatment and surgeon/oncologist preference. This study aimed to quantitatively assess surgeons' attitudes and perceptions about reconstructive options in this setting, and to ascertain if surgical volume influenced advice given. A questionnaire was sent to surgical members of the UK Association of Breast Surgery (ABS) in March-June 2014. The questionnaire elicited information on surgeon volume, reconstructive practice and drivers influencing decision-making. Response rate was 42% (148/355), representing 71% of UK breast units. Delayed breast reconstruction (DBR) was offered more commonly than immediate implant, delayed-immediate or immediate autologous reconstruction (p Quality of Life (HRQoL). Surgeon volume had no effect on reconstruction choice. Common decision-making drivers included negative effects of radiotherapy upon reconstructive and cosmetic outcome. The majority of surgeons (77%) believe the current evidence base is insufficient to guide decision-making. Despite surgeons believing that cosmesis and quality of life are not equivalent between IBR and DBR, DBR remains the commonest approach to this difficult clinical scenario. Surgeons perceive they are using a variety of newer techniques such as Delayed-Immediate Reconstruction and Acellular Dermal Matrices to try to ameliorate the effects of PMRT. This survey demonstrates that there is wide variation in reported surgical practice in this difficult setting. There is widespread acknowledgement of the lack of evidence to guide decision-making.

    Full Text Available Background/Aim. Today, breast reconstruction is a widely accepted method in the treatment of breast cancer after modified radical mastectomy. Reconstruction methods are associated with an acceptable number of complications and reconstruction favorably impacts quality of life. The aim of the study was to present our experience in breast reconstruction. Methods. We presented here a four-year experience with 84 patients with breast reconstruction after modified radical mastectomy. Results. Implant reconstructions were most common, 44 (52.3%, with primary reconstruction in 31(70.4% and secondary in 13 (29.5% women. Lattisimus dorsi flap (LDF and implant were utilized in 32 (38% of the patients, with primary reconstruction in 24 (75% and secondary in 8 (25% women. Transversal rectus abdominis myocutaneous (TRAM flap was rarely used - just in 8 (9.5% patients and only for secondary breast reconstruction. Postoperatively, some early complications such as hematoma, seroma, infections and partial flap necrosis were observed in 10 (11.9% patients. Late complications, such as implant rejection, hypertrophic scarring and hernias at the flap elevation site, were noted in 10 (11.9% cases. Implant loss occurred in 5 (5.9% cases. All the complications were successfully managed, and patients rated their reconstruction as follows: excellent, 49 (59% cases; very good, 20 (24%, and good, 14 (16.8%. In one case, disease progression was observed 6 months after the primary breast reconstruction. Conclusion. Breast reconstruction is an acceptable method in the treatment of breast cancer in patients in the need for or with already performed mastectomy. The choice of reconstruction approach depends on the breast volume, patient's wish and experience of surgical team. Our results suggest the advantage of breast reconstruction with LDF with implant, since the technique is safe, complications relatively rare and easily manageable, and the results are excellent or very good

    In this text, the authors recall the main principles and data ruling cochlear implants. Then, a first circle of technical equipment for assistance is presented. This circle includes: device setting (DS), Electrically evoked Auditory Brainstem Responses (EABR), Neural Response Telemetry (NRT), Stapedial Reflex (SR) and Electrodogram Acquisition (EA). This first cycle becomes more and more important as children are implanted younger and younger; the amount of data available with this assistance makes necessary the use of models (implicit or explicit) to handle this information. Consequently, this field is more open than ever.

    Objective: To observe growth inhibition effect of adeno-associated viral vectors (AAV) mediated angiostatin (ANG) gene on implanted breast cancer in rat and its mechanism. Methods: Gene transfer technique was used to transfer AAV-ANG to the tumor. Growth curves were drawn to observe the growth of breast cancer implanted in rat, and immunohistochemical method was used to detect the effects of angiostatin on microvesel density (MVD) of breast cancer implanted in rat. Results: Angiostatin inhibited the growth of breast cancer implanted in rat and decreased the microvessel density of tumor. Conclusion: Expression of an angiostatin transgene can suppress the growth of breast cancer implanted in rat through the inhibition of the growth of microvessels, surggesting that angiostatin gene transfer technique may be effective against breast cancer.

    Strock, Louis L

    2010-09-01

    Following the return of silicone gel breast implants to the US market in 2006, augmentation with these implants has become increasingly popular. Surgeons have an array of refined techniques from which to choose when performing these procedures, many of which offer the advantage of reduced or less-obvious postoperative scarring. For obvious reasons, many patients are requesting placement of the implants through incisions that are removed from the breast area (and thereby hidden). The challenge of these approaches is to provide a level of technical control that matches what is afforded with the traditional inframammary approach. The addition of endoscopic assistance has provided a level of tissue visualization and technical control not previously possible with the transaxillary approach, with results that rival those of an inframammary procedure. In this article, the author presents his current operative technique, which has allowed for the routine placement of silicone gel breast implants through a transaxillary incision using endoscopic assistance.

Methods The selected study subjects, twelve outpatients from January 2012 to August 2013 in Stomatological Hospital of Yangzhou restored partial bone defects after the primary GBR treatment on the conditon of the alveolar bone resorption and serious bone implant thinning due to cyst of jaw, trauma, dental caries or periodontal disease after the removal of the anterior teeth. The implants were inserted and GBR technique was applied once again 4-6 months later after the healing. Stage II surgeries of dental implantion were done 4-6 months later and dental crown restoration was completed. All the cases in the repair were taken local dental and oral panoramic X-rays at post-operation simultaneously, 3 months later, 6 months later and 12 months later respectively. Follow-up comparisons in peri implant bone level, bone density and osseointergration degree were conducted. Results Two cases of patients with GBR technology and 12 cases of implant were used in the process of planting, and the results showed that the X film was closely related to the alveolar bone. Conclusion The results showed that in all cases with 6 months to 12 months loading the peri implant bone level was stable locating above the first thread and ideal osseointergration was achieved.%目的:观察两次运用引导骨再生技术(GBR)在上颌前牙唇侧区骨质严重缺损种植修复中的应用效果。方法选取2012年1月~2013年8月我院收治的因外伤或颌骨囊肿拔牙后导致牙槽骨严重缺损患者12例作为研究对象,在首次进行GBR恢复部分骨缺损,愈合4~6个月后,再进行种植体植入术,同时再次使用GBR技术。术后4~6月进行种植二期、牙冠修复完成,所有患者均在修复完成当天、3个月、6个月、12个月行局部牙片和口腔全景片,对比种植

    There have been previous studies on the relationship between periodontitis and peri-implantitis, but limited information is available on how periodontitis affects osseointegration and wound healing of newly placed dental implants adjacent to natural teeth. The objective of the present experiment is to evaluate healing around dental implants adjacent to teeth with untreated experimental periodontitis. The study included six male beagle dogs. Scaling and plaque control procedures were performed on three dogs (control group). In the other three dogs (experimental group), retraction cords and ligature wires were placed subgingivally around all premolars and the first molars. Induced experimental periodontitis was confirmed after 3 months. Each control or experimental group was divided into two subgroups depending on the timing of implant placement (immediate/delayed). Twelve dental implants (two implants for each dog) were placed immediately, and the other 12 dental implants (two implants for each dog) were placed 2 months after extraction. The animals were sacrificed 2 months after implant placement. Histologic and histometric analyses were performed. Four implants (three from the immediate placement group and one from the delayed placement group) failed in the experimental group. There were significant differences in the percentage of bone-to-implant contact and marginal bone volume density between the control and experimental groups. Both parameters were significantly lower in the experimental group than in the control group (P implants is associated with a higher failure rate compared with delayed placement. Untreated experimental periodontitis was correlated with compromised osseointegration in the implants with delayed placement.

    The incidence of breast cancer is increasing each year. Concomitantly, cosmetic breast augmentation has become the second most often performed cosmetic surgical procedure. As the augmented patient population ages, an increasing number of breast cancer cases among previously augmented women can be anticipated. The surgical treatment of these patients is controversial, with several questions remaining unanswered. Is breast conservation therapy feasible in this patient population and can these patients retain their implants? A retrospective review of all breast cancer patients with a history of previous augmentation mammaplasty who were treated at the Revlon/UCLA Breast Center between 1991 and 2001 was performed. During the study period, 58 patients were treated. Thirty patients (52 percent) were treated with a modified radical mastectomy with implant removal. Twenty-eight patients (48 percent) underwent breast conservation therapy, which consisted of lumpectomy, axillary lymph node dissection, and radiotherapy. Twenty-two of the patients who underwent breast conservation therapy initially retained their implants. Eleven of those 22 patients (50 percent) ultimately required completion mastectomies with implant removal because of implant complications (two patients), local recurrences (five patients), or the inability to obtain negative margins (four patients). Nine additional patients experienced complications resulting from their implants, including contracture, erosion, pain, and rupture. The data illustrate that breast conservation therapy with maintenance of the implant is not ideal for the majority of augmented patients. Breast conservation therapy with explantation and mastopexy might be appropriate for rare patients with large volumes of native breast tissue. Mastectomy with immediate reconstruction might be a more suitable choice for these patients.

    To investigate the application of combining mastopexy and triple-plane breast augmentation in correction of breast ptosis and atrophy. Peri-areolar incision was performed to finish the fascia and dermal suspension to correct the breast ptosis. The implant was inserted under the pectoralis major muscle through lateral lower border of the gland and a "X" shape full thickness incision was made on the pectoralis major muscle according to the new position of nipple-areolar complex. 14 patients received combined mastopexy and triple-plane breast augmentation to correct breast atrophy and mastopexy simultaneously. All the patients were regularly followed for 6-12 months. No patients suffered severe complication and the results were satisfied. "Triple-plane" breast augmentation could be safely performed with peri-areolar mastopexy with minor injury. The technique could help to ensure the balance between the gland, nipple-areolar complex and the implant.

    1996-09-01

    Acute puerperal mastitis is an inflammatory condition of the breast with an onset 2 to 3 weeks postpartum and often complicated by abscess formation in the affected breast if treatment is delayed. This case demonstrated a periprosthetic seroma in a patient who developed acute puerperal mastitis in the augmented breast that has not been described previously. Treatment of acute puerperal mastitis includes antistaphylococcal antibiotic coverage within the first 48 hours, with ultrasound examination in the presence of persistent induration, swelling, or tenderness to diagnose breast abscess. Plastic surgeons performing breast augmentation need to be aware of this entity.

    Women undergoing unilateral deep inferior epigastric artery perforator (DIEP) flap breast reconstruction may be offered a contralateral symmetrisation either at the time of reconstruction (simultaneous/immediate) or at a later stage (delayed). Simultaneous contralateral breast symmetrisation may be more beneficial to patients and healthcare institutions by avoiding staged surgery, although there is limited evidence on which to base practice. This deficit formed the rationale for our study. The primary outcome was the overall rate of revision surgery. Over a 6-year period, this prospective cohort study recorded the demographics, cancer treatments and operative outcomes of all consecutive unilateral DIEP flap breast reconstructions with or without contralateral symmetrising surgery. Patients were categorised into three groups: (1) simultaneous symmetrisation, 2) delayed symmetrisation and (3) no symmetrisation for comparative analysis. During the study period, 371 women underwent unilateral DIEP flap breast reconstruction 194 (52.3%) were not symmetrised, 155 (41.8%) were simultaneously symmetrised and 22 (5.9%) underwent delayed symmetrisation. Simultaneous symmetrisation of the contralateral breast and unilateral DIEP flap breast reconstruction increased the mean total operative time by 28 min. There were no differences in the rates of peri-operative complications. There were significantly higher rates of all-cause revision surgery (OR 3.97 [1.58, 9.94], p = 0.003) in women undergoing delayed symmetrisation, because of higher rates of revision lipomodelling, scar revision and revision contralateral symmetrisation. Simultaneous contralateral breast symmetrisation was associated with a lower risk of all-cause revision surgery. It is safe, beneficial and likely to be more cost-effective for women undergoing unilateral free DIEP flap breast reconstruction.

    Imaging findings of breast silicone implant rupture are well described in the literature. On MRI, the linguine sign indicates intracapsular rupture, while the presence of silicone particles outside the fibrous capsule indicates extracapsular rupture. The linguine sign is described as the thin, wavy hypodense wall of the implant within the hyperintense silicone on T2-weighted images indicative of rupture of the implant within the naturally formed fibrous capsule. Hyperintense T2 signal outside of the fibrous capsule is indicative of an extracapsular rupture with silicone granuloma formation. We present a rare case of a patient with a silicone calf implant rupture and discuss the MRI findings associated with this condition. (orig.)

    Immediate loading of dental implants has been evolving into an appropriate procedure for the treatment of partially edentulous jaws. The purpose of this study was to evaluate the clinical success and radiological outcome of immediately and delayed loaded dental implants in anterior and premolar sites. In this retrospective study, data of 163 individuals requiring tooth removal with subsequent implant placement in anterior and premolar sites were analyzed. Implants were immediately loaded by provisional acrylic resin bridges or loaded with delay. Implants were followed up annually for up to 9 years including intraoral radiographs. A total of 285 implants in 163 patients were placed. 218 implants were immediately loaded and 67 implants with delay. Fifteen implants failed during the follow-up period resulting in survival rates of 94.5% for immediate loading and 95.5% for delayed loading. After an initial decrease of 0.3 mm in the first 12 months the marginal bone level remained stable. No statistically significant differences were found in marginal bone loss between immediately and delayed loaded implants (P = 0.518, 95% CI). Within the limits of this study, immediate loading of immediately subcrestally placed dental implants in anterior and premolar sites is a reliable treatment option for dental rehabilitation.

  10. Delayed childbearing.

    Science.gov (United States)

    Francis, H H

    1985-06-01

    In many Western nations, including England and Wales, Sweden, and the US, there is a current trend towards delayed childbearing because of women's pursuit of a career, later marriage, a longer interval between marriage and the 1st birth, and the increasing number of divorcees having children in a 2nd marriage. Wives of men in social classes I and II in England and Wales are, on average, having their 1st child at 27.9 years, 1.6 years later than in 1973, and in social classes IV and V, 1.0 years later than in 1973, at a mean age of 23.7 years. Consequently, the total period fertility rate for British women aged 30-34 years, 35-39 years, and 40 and over increased by 4%, 2%, and 4%, respectively, between 1982-83, in contrast to reductions of 2% and 3%, respectively, in the 15-19 year and 20-24 year age groups, with the 25-29-year-olds remaining static. The average maternal mortality for all parties in England and Wales during 1976-78 was 106/million for adolescents, 70.4/million for 20-24 year-olds, and 1162/million for those aged 40 years and older. The specific obstetric and allied conditions which increase with age are the hypertensive diseases of pregnancy, hemorrhage, pulmonary embolism, abortion, cardiac disease, caesarean section, ruptured uterus, and amniotic fluid embolism. The Swedish Medical Birth Registry of all live births and perinatal deaths since 1973 has shown that the risk of late fetal death is significantly greater in women aged 30-39 years than in those of the same parity and gravidity aged 20-24 years. The risk of giving birth to low birth weight babies preterm and at term and of premature labor are similarly increased. The early neonatal death rate also was increased for primigravidas and nulliparas in the 30-39 year age group but not in parous women. This is, in part, due to the rise in incidence of fetal abnormalities with advancing maternal age because of chromosomal and nonchromosomal anomalies. These also appear to be the cause of the

    For a female-to-male transgender person, mastectomy is the most important procedure making the social interaction easier. Along with the size of the breasts, the quantity and quality of skin will influence the selection of surgical technique. Although complications are rare, corrective surgery is performed for as many as 40% of the patients. Of male-to-female transsexual persons, 60 to 70% opt for breast enlargement. Breast enlargement can be carried out by using either silicone implants or fat transplantation. Since the surgical procedures on breasts are irreversible, their implementation requires confirmation of the diagnosis of transsexualism by a multidisciplinary team.

    The choice of implant length is an essential factor in deciding the survival rates of these implants and the overall success of the prosthesis. Placing an implant in the posterior part of the maxilla and mandible has always been very critical due to poor bone quality and quantity. Long implants can be placed in association with complex surgical procedures such as sinus lift and bone augmentation. These techniques are associated with higher cost, increased treatment time and greater morbidity. Hence, there is need for a less invasive treatment option in areas of poor bone quantity and quality. Data related to survival rates of short implants, their design and prosthetic considerations has been compiled and structured in this manuscript with emphasis on the indications, advantages of short implants and critical biomechanical factors to be taken into consideration when choosing to place them. Studies have shown that comparable success rates can be achieved with short implants as those with long implants by decreasing the lateral forces to the prosthesis, eliminating cantilevers, increasing implant surface area and improving implant to abutment connection. Short implants can be considered as an effective treatment alternative in resorbed ridges. Short implants can be considered as a viable treatment option in atrophic ridge cases in order to avoid complex surgical procedures required to place long implants. With improvement in the implant surface geometry and surface texture, there is an increase in the bone implant contact area which provides a good primary stability during osseo-integration.

    Summary Background Currently about 70% of women who suffer from breast cancer undergo breast-conserving therapy (BCT) without removing the entire breast. Thus, this surgical approach is the standard therapy for primary breast cancer. If corrections are necessary, the breast surgeon is faced with irritated skin and higher risks of complications in wound healing. After radiation, an implant-based reconstruction is only recommended in selected cases. Correction of a poor BCT outcome is often onl...

    In 2004, the authors reported their findings with placement of tissue expanders for breast reconstruction in the partial submuscular position, the equivalent of the "dual-plane" technique for breast augmentation. Limitations with subpectoral expander placement include difficulty controlling the lower pole of the pocket during expansion, unprotected device coverage by a thin inferior mastectomy flap, possible effacement of the inframammary fold, and limited control over the superior migration of the pectoralis major muscle. This study aimed to examine the safety and efficacy of an acellular dermal sling in providing inferolateral support to the device during immediate breast reconstruction and expansion. This study prospectively investigated 58 breasts of 43 consecutive women who underwent immediate breast reconstruction with tissue expanders and acellular dermis. After completion of adjuvant therapy and expansion, the devices were exchanged for implants. The patients were tracked through January, 2007. The study parameters included demographic information, oncologic data, complications, and aesthetic outcomes. The mean time required to complete reconstruction was 8.6 months. The overall complication rate after expander/acellular dermis placement was 12%, whereas the complication rate after exchange to implants was 2.2%. The aesthetic outcome for reconstructed breasts did not differ significantly from that for the control subjects who had no surgery. Acellular dermis appears to be a useful adjunct in immediate prosthetic breast reconstruction. Acellular dermis-assisted breast reconstruction has a low complication rate, helps to reconstruct an aesthetically pleasing breast, and facilitates expeditious completion of the reconstruction.

    Full Text Available People with profound hearing loss are not able to use some kinds of conventional amplifiers due to the nature of their loss . In these people, hearing sense is stimulated only when the auditory nerve is activated via electrical stimulation. This stimulation is possible through cochlear implant. In fact, for the deaf people who have good mental health and can not use surgical and medical treatment and also can not benefit from air and bone conduction hearing aids, this device is used if they have normal central auditory system. The basic parts of the device included: Microphone, speech processor, transmitter, stimulator and receiver, and electrode array.

    2005-04-01

    Evidence shows that early implantation of congenitally deaf children is beneficial. However, infants as young as 6 months of age have started to receive cochlear implants (CIs) in the USA. Such early implantation may be associated with higher risks, including anesthetic risk as well as the increased possibility of a false positive in the diagnosis of profound deafness. On the other hand, delaying implantation may be associated with the risk of missing windows of opportunity or sensitive periods for the development of communication skills. In this study, speech perception and language skills in children who received CIs in the first, second, third, or fourth year of life were compared. Participants were tested at regular 6-month intervals after implantation. The effects of several potential confounds were considered. In general, children implanted earlier outperformed those implanted later, with one exception: infants implanted at 6-12 months showed similar outcomes to children implanted at 12-24 months, at least through 2 to 2-1/2 years of age. This preliminary result may be associated with the difficulty of choosing appropriate stimulation parameters for infants, and its potential influence on the quality of the stimulation patterns delivered by the CI.

    Objectives: study of soft and hard tissues around implants. Material and methods: For the immunohistochemical and histological study of the implant/soft tissue interface, we examined pieces of peri-implant mucosa harvested from 35 patients. The implant/bone interface was assessed using histologic and histomorphometric examination of hard tissues around unloaded, early loaded or delayed loaded dental implants with pre-established design, with a sandblasted and acid-etched surface, placed both in extraction sockets, or after bone healing following tooth removal. This study was performed on 9 common race dogs. Results: The histological study of the implant/soft tissue interface showed regenerative modifications and moderate chronic subepithelial inflammatory reactions. Immunohistochemical evaluation of the soft tissue biopsies revealed the presence of specific immunocompetent cells and proteins of the matrix metalloproteinase (MMP) expression. Bone-implants contacts were more obvious in the apical half of the implants and at the edges of the threads, than between them. A mature, lamelliform bone containing lacunae with osteocytes and lack of connective tissue were noticed around implants that were late placed and loaded. The new-formed bone was also abundant in the crestal zone, not only in the apical part of the implants. Conclusions: A thorough understanding of the microstructure of dental implant/soft and hard tissue interface will improve the longevity of osseointegrated implants.

    The displacement of a dental implant into the maxillary sinus may lead to implant failure due to exposure of the apical third or the tip of the implant beyond the bone, resulting in soft tissue growth. This case report discusses dental implant placement in the upper first molar area with maxillary sinus involvement of approximately 2 mm. A new technique for progressive implant loading was used, involving immediately loaded implants with maxillary sinus perforation and low primary stability. Follow-up was performed with resonance frequency analysis and compared with an implant placed adjacent in the upper second premolar area using a conventional delayed loading protocol. Implants with maxillary sinus involvement showed increasing stability during the healing period. We found that progressive implant loading may be a safe technique for the placement of immediately loaded implants with maxillary sinus involvement.

    The application of the KAL-Technique to the field of implant dentistry allows both patients and dental practices to benefit. It is an exciting advance that decreases frustration and stress in providing implant procedures and lowers overall costs. Professionals using the KAL-Technique report significant predictability in achieving passive framework fit. They are also lowering overall cost of implant cases, which increases the number of patients who can accept implant treatment. It has been well established that the more individuals in a practice that receive implants, the more referrals a practice will gain. This is because implant patients find tremendous advances in the quality of life, and do not hesitate to tell others who can take advantage of this opportunity. Implant dentistry is one of the fastest growing fields in dentistry today. While some other areas of dentistry begin to decline in volume and need, implant dentistry provides the opportunity to keep practices strong and to insure long-term success.

  12. Fewer Revisions in Abdominal-based Free Flaps than Latissimus Dorsi Breast Reconstruction after Radiation

    Smith, Benjamin D.; Liu, Jun; Robb, Geoffrey L.; Kronowitz, Steven J.; Garvey, Patrick B.

    2016-01-01

    Background: The most commonly chosen flaps for delayed breast reconstruction after postmastectomy radiation therapy (PMRT) are abdominal-based free flaps (ABFFs) and pedicled latissimus dorsi (LD) musculocutaneous flaps. The short-and long-term advantages and disadvantages of delayed ABFFs versus LD flaps after PMRT remain unclear. We hypothesized that after PMRT, ABFFs would result in fewer postoperative complications and a lower incidence of revision surgery than LD flaps. Methods: We retrospectively reviewed a prospectively maintained database of consecutive patients who underwent unilateral, delayed breast reconstruction after PMRT using ABFFs or pedicled LD flaps with implants at the MD Anderson Cancer Center between January 1, 2001, and December 31, 2011. We compared outcomes and additional surgeries required between the 2 groups. Univariate and multivariate logistic regression modeling analyzed the relationships between patient and reconstruction characteristics and postoperative outcomes. Results: A total of 139 consecutive patients’ breast reconstructions were evaluated: 101 ABFFs (72.7%) versus 38 LDs (27.3%). Average follow-up was similar for ABFF and LD reconstructions. Although ABFF and LD reconstructions experienced similar rates of overall (30.7% vs 23.7%, respectively; P = 0.53), donor-site (8.91% vs 5.13%, respectively; P = 0.48), and flap (20.7% vs 17.9%, respectively; P = 0.37) complications, the LD reconstructions required more additional surgeries (92.1% vs 67.3%; P surgeries more than 1 year after reconstruction (37.1% vs 14.7%; P = 0.02). Conclusion: Although early complication rates were similar for both types of reconstructions, ABFFs seem to have the advantage of providing a more durable result that required fewer revision surgeries in the long term.

  13. Evaluation of the postoperative breast.

    With widespread use of mammography for breast cancer screening, the number of surgical procedures has also increased. Overlapping with radiographic signs of malignancy, including masses, areas of asymmetric density and architectural distortion, microcalcifications, and skin thickening, postsurgical changes may make mammographic evaluation difficult. After tumor excision and irradiation where breast alterations are more profound and prolonged, the task of distinguishing recurrent tumor from scarring or fat necrosis is even more challenging. Mammograms after breast conservation therapy for carcinoma or after cosmetic surgery require correlation with physical findings and the surgical procedures that were performed. Responses of tissue to lumpectomy and radiation, such as breast edema and skin thickening, are most pronounced 6 to 12 months after treatment, gradually resolving within 1 to 3 years. Carefully tailored mammographic studies will promote the dual goal of early detection of local tumor recurrence and avoidance of misinterpreting postoperative and irradiation changes as malignancy. Sequential examinations should begin with a postoperative preradiation mammogram for residual carcinoma, particularly when microcalcifications have been present, followed by the baseline postradiation examination at 6 months with the next study 6 months later (1 year after initial treatment). Mammograms of the treated breast may be performed at intervals of 6 months until radiographic stability has been recognized. Annual studies thereafter are suggested. The contralateral, unaffected breast should be evaluated mammographically according to screening guidelines or clinical concerns. Mammograms performed after cosmetic and reconstructive procedures should be correlated with the surgical techniques and clinical history. Modified views for silicone implants can maximize visualization of breast parenchyma. Ultrasonography is a useful complement to mammography in demonstrating the

To determine the most optimal technique with minimal morbidity, the authors examined their results and complications based on reconstruction timing (immediate and delayed reconstruction and three reconstruction methods: TRAM flap, latissimus dorsi flap and reconstruction with tissue expanders and implants. Methods. Reconstruction was performed in 60 women of mean age 51.1 years. We analyzed risk factors: age, body mass index (BMI, smoking history and radiation therapy in correlation with timing and method of reconstruction. Complications of all three methods of reconstruction were under 1.5-2-year follow-up after the reconstruction. All data were statistically analyzed. Results. Only radiation had significant influence on the occurrence of complications both before and after the reconstruction, while age, smoking and BMI had no considerable influence of the development of complications. There were no statistically significant correlation between the incidence of complications, time and method of reconstruction. Conclusion. Any of the aforementioned breast reconstruction techniques can yield good results and a low rate of re-operations. To choose the best method, the patient needs to be as well informed as possible about the options including the risks and benefits of each method.

  15. [THE EFFECT OF PREGNANCY ON BREAST CANCER].

    2015-08-01

    Cancer and pregnancy coincide in about one in 1,000 pregnancies. One of the most common malignancies associated with pregnancy is breast cancer. Women with pregnancy-associated breast cancer (PABC) have a higher likelihood of being diagnosed with metastatic disease and estrogen receptor (ER) negative tumors than do non-pregnant women. Controversies exist regarding the effect of pregnancy on breast cancer prognosis. Some researchers suggest that pregnancy does not affect breast cancer prognosis, whereas others claim the opposite. Although PABC is usually discovered in an advanced stage, breast cancer metastasis on the placenta is a rare event. During cancer progression, the surrounding microenvironment co-evolves into an activated state through continuous communication with the malignant cells, thereby promoting tumor growth. The effect of pregnancy and placental environment on breast cancer biology is the issue of this review. Placental and cancer cells implantation processes share similar molecular pathways. This suggests that placental factors may affect breast cancer cells biology. Previously, we analyzed the effect of first trimester human placenta on breast cancer cells. Breast cancer cells were co-cultured with placental explants during their implantation on matrigel substrate. We found that the placenta reduced ER expression on the cancer cells and induced their migration and invasion abilities. As a result of it, breast cancer cells migrated away from the placental implantation sites. Hormonal pathways were involved in these phenomena. These results may explain the high incidence of metastases during pregnancy in on the one hand and the rarity of metastases on the placenta on the other hand.

    MRI is well established in the diagnosis of female breast cancer, with an important role as a problem-solving tool in the postoperative breast and in implant evaluation. Little in the literature mentions the use of MRI in male breast cancer, with there is no clear role for its use at present. We present an unusual case of bilateral male breast carcinoma and demonstrate a similar enhancement pattern to that described in female breast cancer; we also suggest other potential applications of MRI ...

    Background There has been an increasing role of acellular dermal matrices (ADMs) and synthetic meshes in both single- and two-stage implant/expander breast reconstruction. Numerous alloplastic adjuncts exist, and these vary in material type, processing, storage, surgical preparation, level of sterility, available sizes and cost. However, there is little published data on most, posing a significant challenge to the reconstructive surgeon trying to compare and select the most suitable product. The aims of this systematic review were to identify, summarize and evaluate the outcomes of studies describing the use of alloplastic adjuncts for post-mastectomy breast reconstruction. The secondary aims were to determine their cost-effectiveness and analyze outcomes in patients who also underwent radiotherapy. Methods Using the PRSIMA 2009 statement, a systematic review was conducted to find articles reporting on the outcomes on the use of alloplastic adjuncts in post-mastectomy breast reconstruction. Multiple databases were searched independently by three authors (Cabalag MS, Miller GS and Chae MP), including: Ovid MEDLINE (1950 to present), Embase (1980 to 2015), PubMed and Cochrane Database of Systematic Reviews. Results Current published literature on available alloplastic adjuncts are predominantly centered on ADMs, both allogeneic and xenogeneic, with few outcome studies available for synthetic meshes. Outcomes on the 89 articles, which met the inclusion criteria, were summarized and analyzed. The reported outcomes on alloplastic adjunct-assisted breast reconstruction were varied, with most data available on the use of ADMs, particularly AlloDerm® (LifeCell, Branchburg, New Jersey, USA). The use of ADMs in single-stage direct-to-implant breast reconstruction resulted in lower complication rates (infection, seroma, implant loss and late revision), and was more cost effective when compared to non-ADM, two-stage reconstruction. The majority of studies demonstrated

    Full Text Available Abstract Introduction Mycobacterium fortuitum is a rapidly growing group of nontuberculous mycobacteria more common in patients with genetic or acquired causes of immune deficiency. There have been few published reports of Mycobacterium fortuitum associated with breast infections mainly associated with breast implant and reconstructive surgery. Case presentation We report a case of a 51-year-old Caucasian woman who presented to our one-stop breast clinic with a two-week history of left breast swelling and tenderness. Following triple assessment and subsequent incision and drainage of a breast abscess, the patient was diagnosed with Mycobacterium fortuitum and treated with antibiotic therapy and surgical debridement. Conclusion This is a rare case of a spontaneous breast abscess secondary to Mycobacterium fortuitum infection. Recommended treatment is long-term antibacterial therapy and surgical debridement for extensive infection or when implants are involved.

    The loss or mutilation of a breast as a result of surgical treatment of neoplastic disease always represents a negative impact on a woman's psyche and negatively influences the quality of the woman's remaining life. The goal of our work was to implement deferred breast reconstruction into routine practice and the objectification of the influence of reconstruction on bodily integrity, quality of life, and the feeling of satisfaction in women. Women in remission from neoplastic disease after a radical mastectomy were indicated for breast reconstruction. Between January 2002 and December 2011 deferred breast reconstruction was carried out 174 × on 163 women, with an average age of 49.2 and an age range of 29-67 years. The most frequently used reconstruction method was a simple gel augmentation of the breast or a Becker expander/implant - 51 (29.3%) and 37 (21.3%), or in combination with a lateral thoracodorsal flap (31; 17.8% and 47; 27%); reconstruction using a free DIEP flap was carried out 7 × (4%). Complications occurred in 19 operations (10.9%) with a dominance of inflammation and pericapsular fibrosis, in a subjective analysis, satisfaction with the results prevailed, along with an increased quality of life after reconstruction. A growing number of deferred breast reconstructions, women's satisfaction with the results, the positive influence of renewed bodily integrity on the feeling of life satisfaction and the quality of life have elevated breast reconstructions to a qualitatively higher level.

    Osseointegration is an important factor in determining the success of a dental implant. It can be assessed from the osseointegration that occurs between the implant and the bone. The implant stability is determined by the osseous support at the implant-bone interface, which is commonly evaluated by histomorphometric analysis. This study aimed to evaluate whether the osseointegration level measured by a Low Resonance Frequency Analyzer (LRFA) gave results as good as those obtained by histomorphometric examination. Six male Macaca fascicularis were used in this study. In each animal, two types of loading were performed: immediate and delayed loading. Clinical examination and LRFA measurement were performed to determine osseointegration at the first and second weeks and at the first, second, third, and fourth months. After four months, histomorphometric examination was performed. The relationship between the histomorphometric examination and LRFA measurement was compared using the Pearson correlation coefficient. There was no significant difference in the osseointegration between immediate loading and delayed loading (p > 0.05) The bone-implant contact percentage in the first group did not differ significantly from that in the second group. Statistical analysis showed that there was a strong correlation between LRFA measurement and histomorphometric examination. Osseointegration could be evaluated through LRFA measurement as well as through histomorphometric examination.

    Full Text Available Retrograde peri-implantitis constitutes an important cause for implant failure. Retrograde peri-implantitis may sometimes prove difficult to identify and hence institution of early treatment may not be possible. This paper presents a report of four cases of (the implant placed developing to retrograde peri-implantitis. Three of these implants were successfully restored to their fully functional state while one was lost due to extensive damage. The paper highlights the importance of recognizing the etiopathogenic mechanisms, preoperative assessment, and a strong postoperative maintenance protocol to avoid retrograde peri-implant inflammation.

    Cochlear implant surgery became the standard of care in hearing rehabilitation of patients with severe to profound sensorineural hearing loss. This procedure may alter the lives of children and adults enabling them to integrate with the hearing population. In the past, implantation was performed only in one ear, despite the fact that binaural hearing is superior to unilateral, especially in noisy conditions. Cochlear implantation may be performed sequentially or simultaneously. The "sensitive period" of time between hearing loss and implantation and between the two implantations, when performed sequentially, significantly influences the results. Shorter time spans between implantations improve the hearing results after implantation. Hearing success after implantation is highly dependent on the rehabilitation process which includes mapping, implant adjustments and hearing training. Bilateral cochlear implantation in children is recommended as the proposed procedure in spite of the additional financial burden.

    Full Text Available Abstract Background Breast gangrene is rare in surgical practice. Gangrene of breast can be idiopathic or secondary to some causative factor. Antibiotics and debridement are used for management. Acute inflammatory infiltrate, severe necrosis of breast tissue, necrotizing arteritis, and venous thrombosis is observed on histopathology. The aim of was to study patients who had breast gangrene. Methods A prospective study of 10 patients who had breast gangrene over a period of 6 years were analyzed Results All the patients in the study group were female. Total of 10 patients were encountered who had breast gangrene. Six patients presented with breast gangrene on the right breast whereas four had on left breast. Out of 10 patients, three had breast abscess after teeth bite followed by gangrene, one had iatrogenic trauma by needle aspiration of erythematous area of breast under septic conditions. Four had history of application of belladonna on cutaneous breast abscess and had then gangrene. All were lactating female. Amongst the rest two were elderly, one of which was a diabetic who had gangrene of breast and had no application of belladonna. All except one had debridement under cover of broad spectrum antibiotics. Three patients had grafting to cover the raw area. Conclusion Breast gangrene occurs rarely. Etiology is variable and mutifactorial. Teeth bite while lactation and the iatrogenic trauma by needle aspiration of breast abscess under unsterlised conditions could be causative. Uncontrolled diabetes can be one more causative factor for the breast gangrene. Belladonna application as a topical agent could be inciting factor. Sometimes gangrene of breast can be idiopathic. Treatment is antibiotics and debridement.

    The normal radiographic appearance of implantable loop recorders has been illustrated in the radiology literature; however, their mammographic appearance has not been described. Breast imagers should become familiar with the appearance of loop recorders in order to create an accurate report. In this paper we report 3 cases of patients with implantable loop recorders who underwent mammography. We describe the types and components of implantable loop recorders, indications for their placement, and their classic appearance on mammography.

    Delay consideration has been a majorissue in design and test of high performance digital circuits. Theassumption of input signal change occurring only when all internal nodesare stable restricts the increase of clock frequency. It is no longertrue for wave pipelining circuits. However, previous logical delaymodels are based on the assumption. In addition, the stable time of arobust delay test generally depends on the longest sensitizable pathdelay. Thus, a new delay model is desirable. This paper explores thenecessity first. Then, Boolean process to analytically describe thelogical and timing behavior of a digital circuit is reviewed. Theconcept of sensitization is redefined precisely in this paper. Based onthe new concept of sensitization, an analytical delay model isintroduced. As a result, many untestable delay faults under thelogical delay model can be tested if the output waveforms can be sampledat more time points. The longest sensitizable path length is computedfor circuit design and delay test.

    Full Text Available The breast feeding practices adopted in terms of duration, frequency and exclusiveness of breast feeding and weaning have great impact on complete physical, mental and psycho-social development of the child. The objective of conducting the study is to evaluate the breast feeding practices adopted by women in urban community, and s to study factors affecting time of initiation of breast feeding, age of weaning, and food given to the baby other than breast milk. The current cross sectional study conducted among 200 women reveal that 70% of mothers were able to start breast feeding within first hour of life after normal delivery. Out of 26 complicated deliveries, 6 mothers were able to start breast feeding within 4 hours of life. The major reasons for delay in starting of breast feeding were uneasiness to mother and not having adequate breast milk. Exclusive breast feeding was practiced by 50% of the mothers for first six month of life. The common reason given by mother for not giving exclusive breast feeding were no knowledge of exclusive breast feeding (40% and not having adequate breast milk(35%. This study emphasizes the need of breast feeding education programme regarding the duration of exclusive breast feeding and the age of weaning.

    Objective: Implant-based breast reconstructions are conceptually simple but prone to surgical revisions. Additional procedures often fail to address the problems associated with the reconstructive outcome, especially in patients who have received radiotherapy. However, conversion to free flaps may improve symptoms and aesthetic results. We reviewed our experience in the United Kingdom with autologous replacement of failed prosthetic reconstructions with the aims of documenting the indications for “tertiary” reconstructions and comparing our outcomes with those of other centers. Methods: Patients undergoing salvage surgery for suboptimal prosthetic breast reconstructions between 2000 and 2012 were retrospectively reviewed for their original reconstructive operation, previous radiotherapy, indications for revision, corrective procedures undertaken, and final outcomes. Results: Of 14 patients identified, 7 had delayed and 7 had immediate reconstructions. Twelve had received radiotherapy; 6 before the initial delayed prosthetic reconstructions and 6 after immediate reconstructions. Ten patients presented after undergoing previous revisions of their original reconstructions (average 1.6). Indications for autologous conversion were capsular contracture, persistent pain, and poor cosmetic outcomes (often in combination). Salvage comprised explantation, total capsulectomy, and abdominal free flap reconstruction using deep inferior epigastric artery flaps (9) and transverse rectus abdominis myocutaneous flaps (5). The average interval between initial reconstruction and salvage was 8 years (r = 1-14). All flap transfers were successful with satisfactory aesthetic outcomes (average 21 months follow-up). Conclusions: We recommend early salvage autologous conversion of implant-based reconstructions once initial prosthetic reconstructions become unsatisfactory, particularly in recipients of radiotherapy. Many of these patients may have been better served by initial

    Full Text Available BackgroundImmediate breast reconstruction after mastectomy and delayed breast reconstruction with post-supplementary treatment are the two types of breast reconstruction currently performed when treating breast cancer. Post-mastectomy radiation therapy (PMRT not only reduces local recurrence but also improves overall survival. However, the complications and survival rates associated with PMRT need to be clear when determining the timing of breast reconstruction. Accordingly, we investigated the optimal timing of breast reconstruction by observing patients who underwent mastectomy followed by PMRT, based on their overall health and aesthetic satisfaction.MethodsWe retrospectively reviewed 21 patients who underwent breast reconstruction with PMRT between November 2004 and November 2010. We collected data regarding the various methods of mastectomy, and the modality of adjuvant therapy, such as chemotherapy, hormone therapy, and radiotherapy. Telephone interviews were conducted to study the general and aesthetic satisfaction.ResultsPatients who received PMRT after breast reconstruction showed a greater complication rate than those undergoing breast reconstruction after PMRT (P=0.02. Aesthetic satisfaction was significantly higher in the groups undergoing breast reconstruction after PMRT (P=0.03. Patients who underwent breast reconstruction before PMRT developed complications more frequently, but they expressed greater aesthetic satisfaction with the treatment.ConclusionsIt is recommended that the complication rates and aesthetic satisfaction after breast reconstruction be carefully considered when determining the optimal timing for radiotherapy.

    Full Text Available The endeavor towards life-like restoration has helped nurture new vistas in the art and science of implant dentistry. The protocol of "restoration-driven implant placement" ensures that the implant is an apical extension of the ideal future restoration and not the opposite. Meticulous pre-implant evaluation of soft and hard tissues, diagnostic cast and use of aesthetic wax-up and radiographic template combined with surgical template can simplify the intricate roadmap for appropriate implant treatment. By applying the harmony of artistic skill, scientific knowledge and clinical expertise, we can simply master the outstanding implant success in requisites of aesthetics, phonetics and function.

    Objective To evaluate complications after post-mastectomy breast reconstruction, particularly in the setting of adjuvant radiotherapy. Summary-Background Data Most studies of complications after breast reconstruction have been conducted at centers of excellence; relatively little is known about complication rates in radiated patients treated in the broader community. This information is relevant for breast cancer patients' decision-making. Methods Using the claims-based MarketScan database, we described complications in 14,894 women undergoing mastectomy for breast cancer from 1998-2007 who received immediate autologous reconstruction (n=2637), immediate implant-based reconstruction (n=3007), or no reconstruction within the first two postoperative years (n=9250). We used a generalized estimating equation to evaluate associations between complications and radiotherapy over time. Results Wound complications were diagnosed within the first two postoperative years in 2.3% of patients without reconstruction, 4.4% with implants, and 9.5% with autologous reconstruction (preconstruction, 20.5% with implants, and 20.7% with autologous reconstruction (preconstruction (OR 1.48, preconstruction (OR=1.55; P=0.01). Conclusions Complication risks after immediate breast reconstruction differ by approach. Radiation therapy appears to modestly increase certain risks, including infection and implant removal.

    Data on the necessity of performing screening mammographies in transsexual women are lacking. The main objective of this study was to assess the possibility to perform mammography and breast sonography in transsexual women. Fifty Dutch-speaking transsexual women were interviewed about the following: attitude towards mammography and breast sonography, importance attributed to and satisfaction with breast appearance, opinion about the necessity of breast check-up, expectations regarding discomfort during the exams and knowledge about the breast surgery. A fasting blood sample, clinical breast exam, mammography and breast sonography were performed. At mammography the following parameters were noted: density, technical quality, location of the prostheses, presence of any abnormalities and painfulness. At sonography the following parameters were recorded: density, presence of cysts, visualisation of retro-areolar ducts or any abnormalities. Twenty-three percent of patients are not aware of the type of breast implants and 79% do not know their position to the pectoral muscles. Patient satisfaction with the appearance of their breasts was rather high (7.94 on a scale of 0-10). Mean expected and experienced pain from mammography was low (4.37 and 2.00 respectively). There was no statistically significant difference in expected pain between those who already had mammography and those who did not. There was a significant positive correlation between the expected and the experienced pain. Mammography and breast sonography were technically feasible and no gross anomalies were detected. Since both exams were judged as nearly painless, 98% of transsexual women intended to come back if they would be invited. Since breast cancer risk in transsexual women is largely unknown and breast exams are very well accepted, breast screening habits in this population should not differ from those of biological women.

    Breast fibromatosis is a rare entity responsible for 0.2% of all solid breast tumors. It has been associated with scars, pregnancy, implants, and familial adenomatous polyposis. We present an interesting case of breast fibromatosis in a 29 year old woman which encroached upon her saline implant and subsequently filled its cavity once the implant was removed. The patient was put on tamoxifen therapy and at 14 month follow-up there was a significant decrease in the size of the mass. Dynamic MRI images are offered for review and current treatment options are discussed.

    The purpose of this systematic literature review was to compare the clinical performance between conventionally- (delayed) and immediately-loaded implants. A literature search of studies published between 1995 and 2012 was performed using several electronic databases and the following key words: "immediate loading", "dental implants", "immediate function", "early loading", "oral implants", "immediate restoration", and "systematic review" was performed. The electronic search was supplemented with hand-searching in dental journals and cross-referencing within the selected articles. Studies were considered for inclusion if they analyzed the success of the immediate loading protocol for implants, with emphasis given to randomized, controlled clinical trials. Among the clinical studies extracted from the literature, 120 studies met the inclusion criteria and were included in this systematic review. These studies included trials that involved yielded consistent results of success rates of immediately-loaded implants comparable to those known from conventionally-loaded implants, which were subjected to the immediate loading protocol or other loading protocols. According to the findings, there is evidence to suggest that immediate loading protocols demonstrate high implant survival rates and could be cautiously recommended for certain clinical situations. However, studies with a high level of evidence, especially randomized, controlled trials, performed over a longer timeframe are required to show a clear benefit over conventional and other loading types.

    Breast implants are high-risk devices that have been at the epicenter of much debate and controversy. In light of the Poly Implant Prothèse crisis, data registries among 11 national societies around the world are cooperatively calling for the urgent need to establish robust national clinical quality registries based on international best practice within a framework of international collaboration. A survey was conducted on the historic and current status of national breast device registries. Eleven countries participated in the study, illustrating different data collection systems and registries around the world. Data collection was designed to illustrate the capabilities of current national registries, with particular focus on capture rate and outcome reporting mechanisms. A study of national breast implant registries revealed that less than half of the participating countries had operational registries and that none of these had adequately high data capture to enable reliable outcome analysis. The study revealed that the two most common problems that discouraged participation are the complexity of data sets and the opt-in consent model. Recent implant crises have highlighted the need for robust registries. This article argues the importance of securing at least 90 percent data capture, which is achievable through the opt-out consent model. Since adopting this model, the Australian Breast Device Registry has increased data capture from 4 percent to over 97 percent. Simultaneously, it is important to foster international collaboration from the outset to avoid duplication of efforts and enable the development of effective international early warning systems.

    Objective To detect the changes of the left ventricular strain indicators in patients with acute myocardial infarction (AMI) after sent implantation by two-dimensional speckle tracking imaging (2D-STI), and to assess the clinical value of strain imaging diastolic index (SI-DI) in evaluation on regional myocardial delayed relaxation after reperfusion. Methods Totally 40 patients with AMI underwent echocardiography before, 1 day, 7 days and 1 month after percutaneous coronary intervention (PCI). Transverse peak strain (Speak), delayed time to peak strain (TPS) and strain imaging diastolic index (SI-DI) with strain imaging in both nonischemic segments and ischemic segments were measured and compared. Results Acute coronary artery occlusion would result in significant deterioration in regional myocardial systolic and diastolic function. Compared to nonischemic myocardium, Speak of ischemic myocardium significantly reduced, TPS significantly prolonged, and SI-DI significantly decreased (all P<0. 05). Speak of ischemic myocardial significantly increased, TPS significantly shorten, and SI-DI increased 7 days and 1 month after PCI (all P<0. 05). Though systolic deformation parameters Speak and TPS returned to normal after 7 days, the diastolic deformation parameter SI-DI of ischemic myocardium returned to normal after 1 month. No significant difference of the parameters in non-ischemic myocardium was found. Conclusion SI-DI can be used to evaluate the left ventricular delayed relaxation or diastolic stunning in patients with AMI after PCI.%目的 应用二维超声斑点追踪显像(STI)技术检测急性心肌梗死(AMI)患者经皮冠状动脉介入治疗术(PCI)后不同时期的左心室心肌应变指标的变化,探讨应变显像舒张指数(SI-DI)对定量评价再灌注后局部心肌舒张功能延迟恢复的临床应用价值.方法 选择40例AMI患者,分别在PCI术前、术后1天、7天及1个月接受超声心动图检查,应用二维应变显像技术

    Gold weight implantation is the most commonly used method for surgical correction of paralytic lagophthalmos. Numerous techniques for placement of the weight have been described, yet complications with these methods continue to occur (implant migration or extrusion, wound infection, failure to correct the lagophthalmos, and excessive postoperative ptosis). We developed a retrograde, postlevator aponeurosis method for implantation to improve the placement and fixation of the weight. This study describes the rationale, technique, and surgical outcome of the retrograde approach. Retrospective analysis. Data maintained and collected on 25 consecutive cases of retrograde upper lid weight implantation for paralytic lagophthalmos. Pre- and postoperative photographs were obtained, and patients were followed for at least 6 months. All procedures were performed by or under the direction of a single surgeon at tertiary academic medical centers (University of California, San Diego and University of Zurich, Switzerland). Twenty-five consecutive patients were evaluated, 16 male and 9 female, ranging in age from 27 to 86 years. There were no surgical failures or perioperative complications and no instances of implant migration or extrusion. One patient developed a delayed infection requiring removal of the implant, and one patient required replacement of the gold weight with a platinum chain implant to better fit the contour of her eyelid. Retrograde implantation allows more accurate placement of the weight while creating a permanent circumferential seal for fixation. The procedure is minimally invasive, less traumatic than previous methods, and produces an excellent cosmetic result. The efficacy has been demonstrated in the outcome of the 25 cases described in this study.

    In recent years, radical breast cancer surgery has been largely replaced by breast conservation treatment, due to early diagnosis and more effective adjuvant treatment. While breast conservation is mostly preferred, the trend of bilateral mastectomy has risen in the United States. The aim of this study is to determine factors influencing patients' choice for having contralateral prophylactic mastectomy (CPM). This is a retrospective study of 373 patients diagnosed with primary invasive breast cancer who were treated by bilateral or unilateral mastectomy (BM or UM) at the Revlon/UCLA Breast Center between Jan. 2002 and Dec. 2010. In the BM group, only those with unilateral breast cancer who chose CPM were included in the analysis. When compared with the UM group, the following factors were found to be associated with BM: younger age, pre-menopausal, a family history of breast/ovarian cancer, BRCA mutation, more breast biopsies, history of breast augmentation, having MRI study within 6 months before the surgery, more likely to have reconstruction and sentinel lymph node biopsy (SLNB) and fewer had neoadjuvant/adjuvant chemotherapy/radiation. When patients with bilateral breast cancer were excluded, multivariate logistic regression analysis indicated younger patients with negative nodes, SLNB as the only nodal surgery and positive family history were significant factors predicting CPM and immediate reconstruction using tissue expanders or implants. Younger age, lower TN stage, requiring only SLNB and high risk family history predict contralateral prophylactic mastectomy. Tissue expander/implant-based reconstructions were more frequently chosen by patients with BM.

    Most described male breast lesions, such as gynecomastia, are benign. The overall incidence of male breast cancer is less than 3%. Like women, common presentations of male breast diseases are palpable lumps or tenderness. Physical examination, mammography and ultrasound are generally used for work-up of breast diseases in both women and men. However, men do not undergo screening mammograms; all male patients are examined in symptomatic cases only. Therefore, all male breast examinations are diagnostic, whereas the majority of the examinations for women are for screening purpose. The differentiation between benign and malignant breast lesions is important, especially for men, because the reported prognosis of male breast cancer is poor due to delayed diagnosis. In this article, we review the spectrum of male breast diseases, from benign to malignant, and illustrate their ultrasonographic and mammographic imaging features.

    In most instances, delayed emergence from anesthesia is attributed to residual anesthetic or analgesic medications. However, delayed emergence can be secondary to unusual causes and present diagnostic dilemmas. Data from clinical studies is scarce and most available published material is comprised of case reports. In this review, we summarize and discuss less common and difficult to diagnose reasons for delayed emergence and present cases from our own experience or reference published case reports/case series. The goal is to draw attention to less common reasons for delayed emergence, identify patient populations that are potentially at risk and to help anesthesiologists identifying a possible cause why their patient is slow to wake up.

    Full Text Available The anterior maxilla presents a challenging milieu interior for ideal placement of implants because of the compromised bone quality. With the advent of intraoral bone harvesting and augmentation techniques, immediate implant placement into fresh extraction sockets have become more predictable. Immediate implant placement has numerous advantages compared to the delayed procedure including superior esthetic and functional outcomes, maintenance of soft and hard tissue integrity and increased patient compliance. This case report exhibits immediate implant placement in the maxillary esthetic zone by combining a minimal invasive autogenous block bone graft harvest technique for ensuring successful osseointegration of the implant at the extraction site.

  20. Breast reconstruction by pedicled transverse rectus abdominis myocutaneous flap

    Directory of Open Access Journals (Sweden)

    Kozarski Jefta

    2004-01-01

    Full Text Available Reconstruction of the amputated breast in female patients after surgical management of breast carcinoma is possible with the use of autologous tissue, synthetic implants, or by combining autologous tissue and synthetic materials. Autologous tissue provides soft and sufficiently elastic tissue which is usable for breast reconstruction and eventually obtains original characteristics of the surrounding tissue on the chest wall. The use of the TRAM flap for breast reconstruction was introduced in 1982 by Hartrampf Scheflan, and Black. The amount of the TRAM flap tissue allows breast reconstruction in the shape most adequate to the remaining breast. The possibilities of using the TRAM flap as pedicled myocutaneous flap or as free TRAM flap make this flap a superior choice for breast reconstruction in comparison with other flaps.

    A rise in incidence and decrease in mortality rates from breast cancer have lead to an increase in prevalence within developed countries. Presentation is classically with a palpable breast tissue mass that may metastasize to bone, lung, liver, brain, lymph nodes, and skin. We describe a delayed diagnosis, in an 80-year-old female patient, where, on 2 occasions, the primary initial presentation was with a cutaneous squamous cell carcinoma in the right axilla. It was not until the third referral, with an ipsilateral breast lump, that breast cancer was clinically diagnosed. This was histologically identified as the primary malignancy, most likely in-keeping with squamous cell carcinoma of the breast. This unique atypical presentation represents a diagnostic challenge and highlights a clinically relevant learning point that may avoid subsequent diagnostic delay. Cutaneous axillary lesions should be treated with a high index of suspicion, necessitating the requirement for chest examination because of the possible presence of an associated primary breast carcinoma.

  4. Counterview: Pre-operative breast MRI (magnetic resonance imaging) is not recommended for all patients with newly diagnosed breast cancer.

    Solin, Lawrence J

    2010-02-01

    For the woman with a newly diagnosed early stage breast cancer, the routine use of pre-operative breast MRI (magnetic resonance imaging) is not indicated beyond conventional breast imaging (i.e., mammography with correlation ultrasound as indicated). There is no consistent evidence that a pre-operative breast MRI confers a benefit to the patient by improving clinical outcomes or surgical procedures. In a meta-analysis of studies reporting on the use of pre-operative breast MRI for the patient with an established index cancer, multifocal or multicentric disease was found on breast MRI in 16% of the patients, a rate substantially higher than the rate of local recurrence after breast conserving surgery plus definitive radiation treatment. In the largest retrospective study of patients treated with breast conserving surgery plus radiation, no gain was found for adding a breast MRI to conventional breast imaging. No randomized clinical trial has been designed to evaluate long term clinical outcomes associated with adding a pre-operative breast MRI. Adding pre-operative breast MRI can alter clinical management in ways that are potentially harmful to patients, for example, increased ipsilateral mastectomies, increased contralateral prophylactic mastectomies, increased work-ups, and delay to definitive surgery. In summary, the routine use of pre-operative breast MRI is not warranted for the typical patient with a newly diagnosed early stage breast cancer.

    Full Text Available Background:. Despite increasing interest in prepectoral implant-based reconstruction to avoid animation deformity (AD, the prevalence of this deformity and patient attitudes toward it have not been extensively studied. The purpose of this study was to report on AD in the breast reconstruction population and identify those at highest risk. Methods:. A retrospective chart review was completed for patients at least 6 months postoperative from subpectoral, implant-based breast reconstruction using acellular dermal matrix in the lower pole. Patient age, BMI, and implant size were collected. A questionnaire was distributed to the patients. Returned questionnaires were compiled and data were analyzed. Results:. Eighty-four of 108 patients (77.8% returned the questionnaire with 62 (75.6% reporting AD; 75.6% of patients were aware of AD, 14.6% considered it moderate, and 11% considered it severe. No statistically significant differences in age, body mass index, implant size, or athleticism were found between those who noted AD versus those who did not. Forty-one of 79 patients (51.9% would have been interested in an initial surgical procedure without AD; interest dropped significantly if the alternative surgery involved increased risk, cost, or additional stages of reconstruction. Conclusion:. The prevalence of AD in subpectoral implant-based breast reconstruction is significantly higher than in subpectoral augmentation. The majority of patients expressed interest in an alternative procedure to avoid AD unless it involved increased risk, cost, or additional surgeries. We found insignificant differences in age, athleticism, BMI, and implant size between patients who note AD and those who do not. Further study is necessary to better define patients at risk for AD to guide patient-centered breast reconstruction.

    The success of dental implant treatment is determined by the primary stability at placement. One factor that could influence this stability is occlusal loading through provisional restoration. Two types of loading protocols are usually used: immediate and delayed loading. However, some controversies remain about the influence of occlusal loading on implant stability. Therefore, the influence of immediate loading on implant stability must be studied. An animal study was conducted by placing nine dental implants
