Background:Robin sequence is defined by the clinical triad of micrognathia, glossoptosis, and upper airway obstruction, and is frequently associated with cleft palate and failure to thrive. Though the efficacy of certain surgical interventions to relieve airway obstruction has been well established, algorithms dictating decision making and perioperative protocols are poorly defined.Methods:A 22-question survey was sent via e-mail to members of the American Cleft Palate-Craniofacial Association and International Society of Craniofacial Surgeons. Questions were related to surgeon experience in treating neonates with Robin sequence, and specific perioperative protocols.Results:One hundred fifty-one responses were collected. Most respondents were surgeons practicing in North America(82.8%), in a university hospital setting (81.5%) and had completed a fellowship in pediatric plastic surgery or craniofacial surgery (76.2%). Preoperative protocols varied widely by years in training and location of practice. Although 78.8% of respondents always performed direct laryngoscopy, only 49.7% of respondents routinely obtained preoperative polysomnography. Mandibular distraction osteogenesis was the most common primary surgical airway intervention reported by 74.2%, with only 12.6% primarily utilizing tongue-lip adhesion. Slightly less than half of respondents ever performed tongue-lip adhesion. Operative selection was influenced by surgeon experience, with 80% of those in practice 0–5 years primarily utilizing mandibular distraction, compared with 56% of respondents in practice >15 years.Conclusions:This study documents wide variations in preoperative, operative, and postoperative protocols for the surgical airway management of neonates with severe Robin sequence. These results underscore the need to acquire more objective data, to compare different protocols and outcome measures.
Surgery within radiated tissue is associated with increased complication rates. It is hypothesized that impaired wound healing may result from aberrant inflammatory responses that occur in previously radiated tissues. Previous work has demonstrated that the topical application of naturally occurring antigen α-gal (Galα1-3Galβ1-(3)4GlcNAc-R) nanoparticles (AGNs) within wounds accelerates macrophage recruitment and subsequent healing in both normal and diabetic wounds. Herein, we hypothesize that application of this antigen would similarly enhance wound healing in irradiated tissues. Methods: To simulate human physiology, α-1,3-galactosyltransferase knockout (KO) mice were exposed to the antigen to produce anti-α-gal antibodies (anti-Gal). Ten days prior to wounding, the dorsal skin was irradiated with 1 session of 40 Gy. Bilateral dorsal 6-mm splinted full-thickness wounds were created within the radiated skin and treated with 50 µL of AGNs (50 mg/mL) immediately after wounding and again on postoperative day 1. A control KO group underwent similar irradiation and wounding protocols but was treated with phosphate-buffered saline (PBS) vehicle. Wild-type (WT) mice, which do not produce anti-Gal, went through the same irradiation and wounding. Results: Histologic analysis demonstrated enhanced epithelial migration in the radiated/AGN-treated KO wounds, which was significantly elevated in comparison to radiated/PBS-treated KO wounds beginning by day 15 and continuing until the end of the study (p < 0.01). In WT mice, treatment with AGNs showed no effect on epithelial migration. Conclusions: Topical application of AGNs onto irradiated wounds significantly ameliorates the delayed wound healing classically seen in radiated skin and results in faster wound closure with only transient application.
We have established a 3-dimensional model to study complex breast cancer-adipose tissue interactions. Direct transfer of fluorescently labeled lipids from adipocytes to breast cancer cells may indicate aberrant metabolism to fuel malignant growth and adaptive survival. Our novel platform can untangle the complex interplay within the breast cancer tumor microenvironment for high-throughput analysis and better elucidate the safety of AFT in postoncologic mastectomy.
Doximity, Inc. has done an excellent job combining their massive medical network with in app features that attempt to streamline the workflow of all healthcare professionals. From easy communication with colleagues, access to a treasure trove of relevant information, and the ability to call patients without the fear of giving away one's private cell phone, all from a clean and simple UI, Doximity is truly an essential tool in the workplace. Unfortunately, the Doximity app cannot be accessed unless you are a healthcare professional. While the application is intended to be a means of communication with colleagues, the app lacks proper messaging features that could allow for consistent workday communication with team members. Fortunately, the application is built on feedback from users, so any desired features are likely already coming down the pipeline. In creating this application, Doximity, Inc. sets out to tackle one of the biggest issues facing healthcare workers and the patients they treat: miscommunication and handoff errors. The Doximity application aims to do this by creating a platform that enables quick and easy communication between physicians, HIPPA-compatible document transfer, and a streamlined service to securely contact patients and colleagues.
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.
