Summary: Volume replacement in oncoplastic breast reconstruction most commonly uses pedicled flaps. In thin patients with small breasts, free-tissue transfer may be better suited to preserve breast size. Evidence on microvascular oncoplastic reconstruction is limited, and reconstruction has often required sacrifice of potential future donor sites. The free superficially based low-abdominal mini (SLAM) flap uses a narrow strip of lower abdominal tissue based on superficial perfusion of the abdominal wall that is anastomosed to chest wall perforators to preserve the ability to perform future abdominally based autologous breast reconstruction. Five patients underwent reconstruction with SLAM flaps for immediate oncoplastic reconstruction. Their mean age was 49.8 years, and their mean body mass index was 23.5. Tumor location was most commonly in the lower outer quadrant (40%). Average lumpectomy weight was 30 g. Two flaps were based on the superficial inferior epigastric artery, and three, on the superficial circumflex iliac artery. Recipient vessels included internal mammary perforators (40%), serratus branch (20%), lateral thoracic vessel branch (20%), and lateral intercostal perforators (20%). All patients underwent radiation therapy without delay and maintained volume, symmetry, and contour at an average period of 11.7 months after surgery. There were no cases of flap loss, fat necrosis, or delayed wound healing. The free SLAM flap allows for immediate oncoplastic breast reconstruction in thin, small-breasted patients with limited regional tissue without sacrificing future potential donor sites for autologous breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Oncoplastic breast reconstruction has improved esthetic results after breast‐conserving surgery with low complication rates and stable oncologic outcomes. Basic principles can be applied across different volume displacement and replacement techniques including restoration of breast shape and symmetry through esthetic incisions while eliminating dead space. Technique selection is guided by several factors including breast size, resection‐to‐breast ratio, and patient desires. A surgeon familiar with all techniques will allow individualization of treatment and optimization of outcomes.

Background: The revenue generated by plastic surgeons assisting other surgical services is poorly captured by hospital accounting systems, which categorize solely by attending physician of record. The financial impact of reconstructive surgery is thus systematically underestimated. The authors sought to quantify the overlooked value of plastic surgeons as consultants who facilitate complex and profitable operations. Methods: Hospital billing data were reviewed for inpatient operations over a 3-year fiscal period (2015 to 2017). Cases in which a plastic surgeon assisted were identified. Case mix index, a measure of complexity that correlates with profit, and contribution margin, defined as revenue minus cost, were obtained for each case. Results: Five hundred fifty-four cases required a reconstructive surgeon; 18,904 nonconsultation cases were identified for comparison. Average net revenue per case involving a consultation was 1.79 times greater than for control cases (p < 0.0001). Average contribution margin was 1.73 times greater (p < 0.005). The highest contribution margins stemmed from joint cases with cardiothoracic surgery and neurosurgery. Case mix index was significantly higher for consultation cases than for controls (4.5 versus 3.9; p < 0.0001). In 434 cases (78 percent), plastic surgery assisted with an integral aspect of the operation, meaning the surgery could not have been technically performed without reconstructive assistance. Conclusions: The authors’ findings demonstrate that cases involving plastic surgeons have a higher profit margin than those performed by any department alone. However, this revenue is not appropriately attributed because of oversimplified financial metrics. The skill set of reconstructive surgeons is an undervalued resource for both patient care and hospital economics.

Technology is changing the way that we live our lives. With the advances in technology, Social Media attains a lot of attention from the people around us. With the advancement of technology, fake news with both political or commercial motives is growing very fast on the internet. Users might be affected easily by falsified news, which has brought about mammoth effects on humanity. The foremost goal is to stop the spread of rumors and focus on the true, substantiate news columns. This paper focuses on techniques such as training deep learning neural network models and natural language processing (NLP) techniques for text analytics based on news titles or news content. These techniques can be used for the treatment of the data. Some of the treating steps are tokenizing the input, lemmatizing it, Stemming and removal of irrelevant words (stop words) are done prior to converting them into N-gram vectors using a technique known as TF-IDF that is term frequency-inverse document frequency. With the help of Machine learning and natural language processing, we will try to aggregate the news and later determine whether the news is real or fake using deep neural networks. Experimental evaluation yields the simplest performance using Term Frequency-Inverted Document Frequency (TF-IDF) as a feature extraction technique.

The use of free flaps in lower extremity reconstructive surgery has seen growing adoption for treating tissue loss in patients with diabetes mellitus and peripheral artery disease as a means for limb preservation. The superficial circumflex iliac perforator artery (SCIP) flap is one of the most commonly utilized flaps in foot reconstruction and has demonstrated benefits over amputation. Patients with impaired vascular and neurologic function are predisposed to complications following lower extremity reconstructive surgery, particularly ischemia in the angiosomes of the arteries used for flap anastomosis. We present the case of a patient who underwent successful SCIP flap reconstruction of the calcaneus but developed gangrene in the forefoot region supplied by a hypoplastic posterior tibial artery in subsequent months. The changes in tissue oxygenation and hemoglobin distribution of the foot are shown using spatial frequency domain imaging throughout the flap healing process and eventual tissue necrosis.

As the sophistication of microsurgical breast reconstruction continues to evolve, plastic surgeons are focusing on techniques to improve functional and psychosocial outcomes for patients, including breast sensation. Interest in neurotization of breast flaps, among both patients and surgeons, has grown significantly in recent years. This study aimed to review the outcomes of neurotization across autologous flap reconstructions, to provide a comprehensive analysis of the efficacy of this technique in improving postoperative sensory recovery.

Background: Lymphedema is a condition characterized by dysfunction of the lymphatic system resulting in chronic, progressive soft tissue edema that can negatively impact individuals' function, self-image, and quality of life. Understanding of the disease process has evolved significantly in the past two decades with advances in diagnostic modalities and surgical techniques revolutionizing prior treatment algorithms. Methods and Results: We reviewed our current approach at the University of Southern California to improving outcomes in lymphedema treatment. Given the complexity of this medical condition, patients are best served by a multidisciplinary approach. At our institution, this involves a collaborative effort between bench researchers, lymphatic therapists, medical physicians, and lymphedema surgeons. Basic science and translational research provide further understanding into the underlying mechanisms of lymphangiogenesis and the possibility for potential therapeutic interventions. Our surgical algorithms require patients to undergo a thorough diagnostic evaluation and consultation with certified lymphatic therapists prior to undergoing either physiologic or debulking operations. Patients are followed clinically following any interventions. Further community outreach and education is carried out in order to improve upon early diagnosis and symptom recognition. Conclusions: Optimizing lymphedema care requires a collaborative interplay between researchers, physicians, and therapists. Additionally, patient and provider education on early disease recognition and treatment options is an equally critical aspect of improving patient outcomes.
