Introduction: The use of prosthetic mesh in hernia repair provides a powerful tool to increase repair longevity, decrease recurrence rates, and facilitate complex abdominal wall reconstruction. Overall infection rates with mesh are low, but for those affected there is high morbidity and economic cost. The availability of a practicable small animal model would be advantageous for the preclinical testing of prophylactics, therapeutics, and new biomaterials. To this end, we have developed a novel mouse model for implantation of methicillin-resistant Staphylococcus aureus–infected surgical mesh and provide results from antibiotic and immunotherapeutic testing. Materials and Methods: Implantation of surgical mesh between fascial …

Objective: Assessment of the quality of the final product (QFP) is critical in simulation training, such as the clock face suture (CFS) exercise that is used to assess trainees’ needle handling and suturing accuracy. Objective Structured Assessment of Technical Skill (OSATS) scores are the gold standard for the evaluation of trainees. The aim was to investigate variability in the use of OSATS checklists and to evaluate a semi-automatic method of suture analysis vs. OSATS scores. Methods: Details of 287 CFSs performed by trainees during Fundamentals in Vascular Surgery examinations were collected. All were rated according to a seven item OSATS …

Background and Aims: Minimally adherent silver dressings (SILVER MASD) are antimicrobial, nonirritating, provide a moist wound healing environment, and low cost. The purpose of this pilot, single-center, non-blinded randomized controlled trial was to quantify the outcomes of acute surgical wounds treated with MASD versus standard of care (SoC) dressings. Methods: Thirty-two patients with acute wounds were randomized 1:1 to be treated with MASD once weekly or SoC following surgical excision of skin and/or subcutaneous tissue between September 13, 2016 and November 28, 2017. The outcome variables included clinical infection, time to wound closure, and pain scores at dressing changes. Two …

Background: This report describes the presentation and course of treatment for one of the youngest reported cases of empyema of the gallbladder. Given the rare occurrence of this disease process, we elected to proceed with a systematic review of the literature. This is only the 7th case series discussing pediatric empyema of the gallbladder due to Salmonella typhi in the literature, and the second case ever reported in the USA. Case presentation: We report a case of a previously healthy 13-month-old girl who presented with diffuse peritonitis and equivocal imaging studies. Diagnostic laparoscopy revealed purulent peritonitis. The gallbladder was distended …

Objective: Build a microlaryngoscopy surgical simulator for endoscopic laryngeal surgery using standard microsurgical instruments and a CO2 laser. Study design: Anatomical modeling, CAD design and 3D printed manufacturing. Subjects and methods: We created a modular design for a microlaryngoscopy simulator in CAD software. Components include plastic and stainless-steel models of a standard operating laryngoscope and a cassette system for mounting porcine or synthetic models of the vocal folds. All simulator parts, including the metallic laryngoscope model, were manufactured using 3D printing technology. Tumors were simulated in porcine tissue models by injecting a soy protein-based tumor phantom. Residents and faculty in …

COVID-19 morbidity and mortality are driven by poor immune regulation. Narrowband ultraviolet B (NB-UVB) phototherapy is standard of care in a number of immune-dysregulated diseases. To assess the efficacy of NB-UVB phototherapy for improving COVID-19 outcomes in high-risk, hospitalized, we developed the Adaptive Photo-Protection Trial. This is a multi-center, prospective, double-blinded, randomized, placebo-controlled trial. The pilot phase results are reported here. Consecutive patients admitted with a positive COVID-19 PCR were screened for eligibility. Enrolled subjects were computer randomized 1:1 to NB-UVB or placebo phototherapy. Subjects were treated daily with escalating doses on 27% of their body surface area for up …
Expression Of The Preadipocyte Marker Zfp423 Is Dysregulated Between Well-Differentiated And Dedifferentiated Liposarcoma, Thanh N. Dang, Rafael P. Tiongco, Loren M. Brown, Jessica L. Taylor, John M. Lyons, Frank H. Lau, Z. Elizabeth Floyd

Background: Well-differentiated and dedifferentiated liposarcomas are rare soft tissue tumors originating in adipose tissue that share genetic abnormalities but have significantly different metastatic potential. Dedifferentiated liposarcoma (DDLPS) is highly aggressive and has an overall 5-year survival rate of 30% as compared to 90% for well-differentiated liposarcoma (WDLPS). This discrepancy may be connected to their potential to form adipocytes, where WDLPS is adipogenic but DDLPS is adipogenic-impaired. Normal adipogenesis requires Zinc Finger Protein 423 (ZFP423), a transcriptional coregulator of Perixosome Proliferator Activated Receptor gamma (PPARG2) mRNA expression that defines committed preadipocytes. Expression of ZFP423 in preadipocytes is promoted by Seven-In-Absentia Homolog …

Background: Laser interstitial thermal therapy (LITT) has emerged as a treatment option for deep-seated primary and metastatic brain lesions; however, hardly any data exist regarding LITT for lesions of the posterior fossa. Methods: A quantitative systematic review was performed. Article selection was performed by searching MEDLINE (using PubMed), Scopus, and Cochrane electronic bibliographic databases. Inclusion criteria were studies assessing LITT on posterior fossa tumors. Results: 16 studies comprising 150 patients (76.1% female) with a mean age of 56.47 years between 2014 and 2021 were systematically reviewed for treatment outcomes and efficacy. Morbidity and mortality data could be extracted for 131 …
