Phase-Transformation Nanoparticle-Mediated Sonodynamic Remedy: An Effective Method to improve Anti-Tumor Defense Reply by simply Inducing Immunogenic Cellular Demise within Breast Cancer.
The clinical results with extracellular matrix biomaterials are confounded by expectations of material response based on years of experience with permanent or degradable synthetic polymers. However, the remodeling or assimilation of extracellular matrix biomaterials is dictated by cell-mediated processes rather than fibrous encapsulation or hydrolytic degradation. RepSox datasheet Previously, we found that tissue adherence and revascularization were dictated by proximity with de-epithelialized host tissue. We now investigate the effects of polymer and fixation type on attachment strength and rate of cell repopulation in an intra-abdominal implant model. Methods An intra-abdominal implant model in rats was used to probe assimilation properties at 4 weeks and 12 weeks with permanent and degradable suture types as well a combination of suture and biologic attachment (mesothelial abrasion). The mechanical strength of the attachment was measured by peel testing and the repopulation by automated cell counting of histologic sections. Results The intensity of the biologic response was greater with degradable polymers than permanent polypropylene. Tissue attachment strength ranged from 2 to 15 N but changed in elasticity with time. The magnitude and distribution of cell repopulation was highly variable by suture type but ultimately did not affect the long-term strength of the soft tissue attachment. Conclusions The tissue approximating polymer sutures were stretchy and of similar strength regardless of degradation rate or polymer type. The strongest attachment, most rapid repopulation of the deep matrix regions, and most uniform distribution of cells were found with the addition of biologic attachment.Female genital mutilation (FGM) is a growing problem in the United States, with the past few decades showing a dramatic increase in prevalence. This study aims to understand the plastic surgeon experience with FGM and inform preparedness for this rising problem. Methods A 26-question survey was developed and electronically distributed to a random cohort of 2,508 active American Society of Plastic Surgeons members. It was sent three times over a 3-week period in 2018. χ2 statistical tests were used to analyze outcomes, assuming a P less then 0.05 level for statistical significance. Results There was a 7% survey response rate (n=180). Demographic profiles reflected a range of practice types, geographical distribution, and years of experience. Ninety-five percent of respondents had heard of FGM (n=169). Sixty-seven percent were aware that surgical reconstructive options exist for FGM (n=115), with only 5% reporting any formal training on the topic (n=10). Only 13.6% of those surveyed felt prepared to care for a woman with FGM (n=23). Conclusions After surveying plastic surgeons, responses demonstrate that while the majority are familiar with FGM, very few are comfortable or prepared for the care and surgical management of this patient population. Although this study is limited by a low response rate, we believe that the results reflect an existing knowledge gap and demonstrate the need for formal training. This may help to bridge this gap and prepare surgeons to care for this population.Osseous work in facial feminization has been largely developed by comparing the qualitative and quantitative anthropometric differences between male and female cadaveric skulls. While virtual surgical planning has allowed for improved accuracy and ease in osteotomies and recontouring procedures in facial feminization, ultimately, a subjective decision-making process is still required. In this work, we describe a novel method of simplifying facial feminization by virtually modeling all osseous surgical maneuvers for facial feminization with a reference female skull.Craniosynostosis affects 1 in 2,000 live births, which makes it one of the most common craniofacial abnormalities in the United States. Despite this fact, few national epidemiologic reports exist, although US and European studies have reported an increased incidence of metopic craniosynostosis. The aim of our study is to analyze the National Inpatient Sample (NIS) to support those conclusions. Methods We identified hospitalizations from 1998 to 2012 by using the ICD-9-CM diagnosis code for congenital anomalies of skull and face bones (756.0) and procedure codes related to craniosynostosis repair (2.01, 2.03, 2.04, 2.06). Results We analyzed data from 37,815 hospitalizations and 49,505 reconstructive procedures. There was a 61.6% increase in the number of hospitalizations related to craniosynostosis repairs. There was a 180% increase in bone graft to skull procedures, 109% increase in other cranial osteoplasty, 54% increase in formation of cranial bone flap, and a 6% decrease in opening of cranial suture. Conclusions We observed a steady rise in the number of craniosynostosis repairs performed, but whether this is a result of a true increase in incidence, better diagnosis, or change in treatment patterns needs further research. The current classification system does not provide information about the specific suture affected (metopic, sagittal, etc.), the type of repair performed (endoscopic, fronto-orbito advancement, etc.), and whether the repair is a primary procedure or a revision. More descriptive diagnosis and procedural codes are imperative to improve the epidemiologic and outcomes data of craniosynostosis in the United States.Telemedicine is an application of modern technology that allows for the remote delivery of healthcare services to diagnose and treat patients. The potential patient benefits of such a program include added convenience, lowered costs, and improved access. From a practical standpoint, establishing a telemedicine program may seem daunting to the plastic surgeon; success requires not only patient and provider adoption, but also integration of new technology. Despite these challenges, breast reconstruction patients are among those who stand to benefit most from telemedicine technology, as this patient population remains vulnerable to limitations to access following an emotion-provoking breast cancer diagnosis. Geographical limitation, especially in rural areas, represents a major barrier to access. To date, the application of telemedicine in caring for breast reconstruction patients has not been described in the literature. In this article, we describe the protocol developed and implemented by our academic plastic surgery group to care for new breast reconstruction candidates and discuss the role of telemedicine in improved access to breast reconstruction care.
