BACKGROUND: Over 90% of women report to be very dissatisfied with the aspect of their breast after bariatric surgery. Breast reconstructive surgeries are often not funded by the National Health Service or private health insurances in many countries and the patient must pay a high economic amount to undergo it. PATIENTS AND METHODS: A prospective randomized clinical trial of patients undergoing bariatric surgery was performed. Patients were randomly assigned into 3 groups: patients undergoing percutaneous electrostimulation of the pectoral muscle combined with specific training (group 1), patients doing the specific training alone (group 2), and patients without any specific treatment (group 3)...

BACKGROUND: With the development of new surgical techniques in breast cancer, such as oncoplastic breast surgery, increased knowledge of risk factors for poor satisfaction with conventional breast-conserving surgery (BCS) is needed in order to determine which patients to offer these techniques to. The aim of this study was to investigate patient satisfaction regarding aesthetic result and skin sensitivity in relation to patient, tumour, and treatment factors, in a consecutive sample of patients undergoing conventional BCS...

: 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...

Background Higher body mass index (BMI) has been shown to increase postoperative complications in autologous breast reconstruction. However, the correlation with flap weight is unknown. Here, we explore the relationship of flap weights and complication rates in patients undergoing microvascular breast reconstruction. Methods Retrospective chart review identified all patients undergoing microvascular breast reconstruction with abdominally based flaps at a single institution between November 2007 and April 2013...

Herein, we first describe a perfusion chip integrated with an AC electrothermal (ACET) micromixer to supply a uniform drug concentration to tumor cells. The in-plane fluid microvortices for mixing were generated by six pairs of reconstructed novel ACET asymmetric electrodes. To enhance the mixing efficiency, the novel ACET electrodes with rotating angles of 0°, 30°, and 60° were investigated. The asymmetric electrodes with a rotating angle of 60° exhibited the highest mixing efficiency by both simulated and experimental results...

Ultrasound imaging is used for detecting and characterizing breast lesions. A state of the art imaging method is the contrast source inversion (CSI), which solves the full wave nonlinear inverse problem. However, when the measurements are acquired in noisy environments, CSI can diverge from the correct solution after several iterations. Problems associated with noisy data were originally solved by including total variation (TV) regularization. Unfortunately, for very noisy data, TV regularization alone is not sufficient...

UK best practice guidelines for oncoplastic breast reconstruction were published in 2012. Implant-based reconstruction quality indicator (QI) targets for readmission, return to theatre and implant loss rates were set at 5% by 3 months, along with guidance to achieve these targets. The aims of this study were to quantify complication rates following implant-based reconstruction before and after the implementation of the guidelines. A retrospective audit of 86 patients with 106 implants in the 12 months to June 2013 was performed, C1...

Post-mastectomy reconstruction is performed using implant-based or autologous techniques. Many women refuse or are poor candidates for implant-based reconstruction. We previously described a single-stage autologous technique that was most applicable in obese women with significant ptosis that made use of the mastectomy skin flap and subcutaneous tissue to reconstruct a breast mound. Here, we extend this technique to smaller breasted women by incorporating a second stage of skin tailoring and fat grafting. This technique does not require donor site surgery nor extended operative and recovery times...

BACKGROUND: The evidence to support dressing standards for breast surgery wounds is empiric and scarce. OBJECTIVE: This two-arm randomized clinical trial was designed to assess the effect of dressing wear time on surgical site infection (SSI) rates, skin colonization and patient perceptions. METHODS: A total of 200 breast cancer patients undergoing breast reconstruction were prospectively enrolled. Patients were randomly allocated to group I (dressing removed on the first postoperative day, n = 100) or group II (dressing removed on the sixth postoperative day, n = 100)...

OBJECTIVE: In postmastectomy reconstruction, procedure choice is heavily influenced by the relative risks of the various options. This study sought to evaluate complications in a large, multicenter patient population. SUMMARY OF BACKGROUND DATA: Previous studies have reported widely varying complication rates, but have been limited by their single center designs and inadequate controlling for confounders in their analyses. METHODS: Eleven sites enrolled women undergoing first time, immediate, or delayed reconstruction following mastectomy for cancer treatment or prophylaxis...

OBJECTIVE: Reconstruction following mastectomy offers women an opportunity to mollify some of the emotional and aesthetic effects of this devastating disease. PATIENTS AND METHODS: The authors reviewed the files of 83 patients who underwent immediate postmastectomy reconstruction with tissue expander between January of 2003 and June of 2012 at our hospital. The patients were divided into two groups: Group A (study group) included 30 patients with previous quadrantectomy and radiotherapy who underwent salvage mastectomy after local recurrence; Group B (control group) included 53 patients submitted to primary radical mastectomy...

Optoacoustic tomography (OAT), also known as photoacoustic tomography, is a rapidly emerging hybrid imaging technique that possesses great potential for a wide range of biomedical imaging applications. In OAT, a laser is employed to illuminate the tissue of interest and acoustic signals are produced via the photoacoustic effect. From these data, an estimate of the distribution of the absorbed optical energy density within the tissue is reconstructed, referred to as the object function. This quantity is defined, in part, by the distribution of light fluence within the tissue that is established by the laser source...

This study investigates shear wave phase map reconstruction using a limited number of color flow images (CFIs) acquired with a color Doppler ultrasound imaging instrument. We propose an efficient reconstruction method to considerably reduce the number of CFIs required for reconstruction and compare this method with Fourier analysis-based color Doppler shear wave imaging. The proposed method uses a two-step phase reconstruction process, including an initial phase map derived from four CFIs using an advanced iterative algorithm of optical interferometry...

High-resolution imaging of densely connected samples such as pathology slides using digital in-line holographic microscopy requires the acquisition of several holograms, e.g., at >6-8 different sample-to-sensor distances, to achieve robust phase recovery and coherent imaging of specimen. Reducing the number of these holographic measurements would normally result in reconstruction artifacts and loss of image quality, which would be detrimental especially for biomedical and diagnostics-related applications...

OBJECTIVE: Currently, dynamic contrast-enhanced (DCE) breast magnetic resonance imaging (MRI) prioritizes spatial resolution over temporal resolution given the limitations of acquisition techniques. The purpose of our intrapatient study was to assess the ability of a novel high spatial and high temporal resolution DCE breast MRI method to maintain image quality compared with the clinical standard-of-care (SOC) MRI. MATERIALS AND METHODS: Thirty patients, each demonstrating a focal area of enhancement (29 benign, 1 cancer) on their SOC MRI, consented to undergo a research DCE breast MRI on a second date...

BACKGROUND: The use of acellular dermal matrix (ADM) in implant-based immediate breast reconstruction has been increasing. The current ADMs available for breast reconstruction are offered as aseptic or sterile. No published studies have compared aseptic and sterile ADM in implant-based immediate breast reconstruction. The authors performed a retrospective study to evaluate the outcomes of aseptic versus sterile ADM in implant-based immediate breast reconstruction. METHODS: Implant-based immediate breast reconstructions with ADM conducted between April 2013 and January 2016 were included...

Considering the high incidence of breast cancer and the subsequent need for a mastectomy, the number of patients having breast reconstruction remains relatively low the world over. Most studies from the west show that anywhere between 5% to around 50% of women proceed to reconstruction following a complete mastectomy. There is a great paucity of literature on the subject in Pakistan. Anecdotal and unofficial accounts would suggest that less than a fraction of 1% of women in Pakistan undergo reconstruction following a mastectomy...
