Infections following orthopedic device implantations often impose a substantial health burden and result in high medical costs. Currently, preventative methods are often employed following an orthopedic implant to reduce risk of infection; however, contamination of the surgical site can still occur. Although antibiotics have demonstrated a substantial reduction in bacterial growth and maintenance, biofilm formation around the implant can often minimize efficacy of the antibiotic. Recently, nanotechnology has garnered significant interest, resulting in the development of several antibiotic delivery strategies that exhibit extended release and increased efficacy. In this review, treatment methods of orthopedic-device-related infections will be discussed and an overview of antimicrobial-based nanotechnologies will be provided. Specifically, nonmetal-, metal- and oxide-based nanotechnologies, incorporating antibacterial strategies, will be discussed.
Background Not all women undergo breast reconstruction despite its vital role in the recovery process. Previous studies have reported that women who are ethnically diverse and of lower socioeconomic status are less likely to undergo breast reconstruction, but the reasons remain unclear. The purpose of this study is to evaluate the demographic characteristics of our patient population and their primary reason for not undergoing breast reconstruction. Methods An institutional review board-approved, single-institution study was designed to evaluate all female breast cancer patients of all stages who underwent mastectomy but did not undergo breast reconstruction from 2008 to 2014. Patients were contacted via telephone and asked to participate in a validated, prompted survey. Data regarding their demographic information and primary reason for not undergoing breast reconstruction were collected. Results Inclusion criteria were met by 181 patients, of which 61% participated in the survey. Overall, the most common reason for not undergoing breast reconstruction (26%) was unwillingness to undergo further procedures. However, the most common reason for patients that identified as Hispanic, Spanish-speaking, high school graduates, or having an annual income less than US $25,000 (P < 0.05) was insufficient information received. Conclusions This study demonstrates that ethnicity and socioeconomic factors play a key role in determining why patients forego breast reconstruction. Ethnicity, language, education, income, and employment status are associated with patients not receiving appropriate education regarding their reconstructive options. Breast surgeons with a diverse patient population should ensure that these patients are adequately educated regarding their options, and if perhaps, more of these patients would decide to partake in the reconstruction process.
Despite its numerous benefits, peritoneal dialysis (PD) can rarely result in dangerous and even life-threatening complications, including peritonitis, hernias, encapsulating peritoneal sclerosis (EPS), and rarely peritoneal pseudocysts. Herein, we present a rare case of a giant intra-peritoneal pseudocyst that presented four months following the discontinuation of a 5-year course of complicated PD. Despite the initially successful drainages, the patient’s symptoms continued to recur, and the imaging findings were concerning for underlying neoplastic processes. As such, a staged surgical approach was performed, starting with a diagnostic laparoscopy and was subsequently followed with cyst excision and marsupialization to the peritoneal cavity. While previous reports of such rare pseudocyst have been documented in the literature as a complication of PD, to our knowledge, this is the second case of pseudocyst formation to occur months after the discontinuation of PD therapy. This case emphasizes the importance of close follow-up in PD patients and showcases how a staged surgical approach can be utilized to accurately diagnose and manage such complicated cases.
Over the last few decades, extracorporeal membrane oxygenation (ECMO) has become a lifesaving modality for patients with severe respiratory failure following burn injury. With the advancement in critical care and ECMO management, this study aims to analyze the outcomes of ECMO in pediatric burn patients. The Extracorporeal Life Support Organization database was queried from 1999 to 2018 for patients 18 years old and under with a burn injury. The data were divided into two decades, the first (1999–2008) and the second (2009–2018), for analysis of background characteristics and clinical outcomes. Ninety-five patients met inclusion criteria. The overall use of ECMO increased in the second decade (60 cases) when compared to the first decade (35 cases), and use of venovenous ECMO increased in the second decade from 16 cases to 38 cases. Although more patients survived because of the increased application of venovenous ECMO, the survival rate was unchanged between decades (53.4% vs. 54.3%; P = 0.937). Patients with pre-ECMO cardiac arrest had a significant improvement in mortality during the second decade (54.5% vs. 0%; P = 0.043). Metabolic (P = 0.022) and renal (P = 0.043) complications were most common in nonsurvivors during the first decade whereas cardiovascular (P = 0.031) and neurologic (P = 0.003) complication were higher in the second decade (P = 0.031, 0.003). Use of ECMO after burn injury has become more common; however, overall mortality remains unchanged. The data suggests pre-ECMO cardiac arrest is no longer a contraindication to start ECMO.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
