Evidence-Based Approach For Prevention Of Surgical Site Infection, Mehmet Kursat Yilmaz, Nursanem Celik, Saad Tarabichi, Ahmad Abbaszadeh, Javad Parvizi

Rothman Institute Papers

Periprosthetic joint infection (PJI) is regarded as a critical factor contributing to the failure of primary and revision total joint arthroplasty (TJA). With the increasing prevalence of TJA, a significant increase in the incidence of PJI is expected. The escalating number of cases, along with the significant economic strain imposed on healthcare systems, place emphasis on the pressing need for development of effective strategies for prevention. PJI not only affects patient outcomes but also increases mortality rates, thus its prevention is a matter of vital importance. The longer-term survival rates for PJI after total hip and knee arthroplasty correspond with …

Utilization Of Blood Flow Restriction Therapy With A Former Triathlete After Total Knee Arthroplasty: A Case Report, Christopher Keating, Stephanie Muth, Pt, Phd, Cameron Hui, Lisa T. Hoglund

Department of Physical Therapy Faculty Papers

INTRODUCTION AND PURPOSE: Knee osteoarthritis (OA) is a common condition that limits function and reduces quality of life. Total knee arthroplasty (TKA) is a surgical procedure that replaces the joint surfaces to address anatomical changes due to knee OA. While TKA improves symptoms and function, postoperative impairments are common, including reduced quadriceps strength. Blood flow restriction (BFR) may be a viable option for patients following TKA, as it can improve strength with a minimal amount of joint loading compared to traditional strength training. The purpose of this case report is to describe the impact of BFR use in an individual …

Skin Necrosis Following Digital Wart Intralesional Injection Of Cantharidin, Sebastian Arango, Tristan Weir, Andrew Miller, Meredith Osterman

Department of Orthopaedic Surgery Faculty Papers

A right-hand-dominant female presented 5 weeks following a right middle finger intralesional cantharidin injection for a common wart by a dermatologist. The patient experienced progressive stiffness, blistering, swelling, pain, and ultimately, full-thickness skin necrosis surrounding the injection site. Careful debridement followed by a full-thickness skin graft was performed with no evidence of involvement of the germinal matrix or terminal extensor tendon. At the 7-month postoperative mark, the patient’s graft exhibited favorable healing and improved functionality that did not require further follow-up. Intralesional injection of cantharidin solutions for digital warts leads to progressive skin necrosis. Our case required prompt debridement and …

BACKGROUND: Autologous chondrocyte implantation (ACI) and matrix-induced autologous chondrocyte implantation (MACI) are 2-stage procedures requiring an index full-thickness cartilage biopsy. Only a portion of patients ultimately undergo second-stage ACI/MACI.

PURPOSE: To identify patients with articular cartilage defects who underwent arthroscopic debridement with biopsy for ACI/MACI and compare those who did with those who did not proceed with implantation within 2 years after biopsy. Additionally, the authors sought to identify why patients did not proceed with implantation.

STUDY DESIGN: Case-control study; Level of evidence, 3.

METHODS: Patients who underwent arthroscopy and autologous chondrocyte biopsy from January 1, 2015, to December 31, …

Emergency Department Slit Lamp Interdisciplinary Training Via Longitudinal Assessment In Medical Practice, Samara Hamou, Shayan Ghiaee, Christine Chung, Maureen Lloyd, Kelly Khem, Xiao Zhang

Department of Emergency Medicine Faculty Papers

INTRODUCTION: Eye emergencies make up nearly 3% of US emergency department (ED) visits. While emergency physicians (EP) should diagnose and treat these ophthalmologic emergencies, many trainees report limited ocular exposure and insufficient training throughout their residency to confidently conduct a thorough slit-lamp exam.

METHODS: We created an interdisciplinary, simulation-based mastery learning (SBML) curriculum to teach emergency attending physicians how to operate the slit lamp with multimodal learning methodology at a tertiary academic center. The EPs first demonstrate their initial slit-lamp competency with a 20-item checklist, and they then review the necessary curricular content to pass their independent readiness test before …

Hereditary Spherocytosis Due To A Novel Variant, P.Q1034x, In The Beta Subunit Of The Spectrin Gene: A Case Report, Emmalee M. Kugler, Akash Patel, Faraz Afridi, Maria I. Scarano, Rafat Ahmed

Department of Emergency Medicine Faculty Papers

Background: Heterozygous pathogenic variants of SPTB cause hereditary spherocytosis (HS) in a quarter of cases. Case report: A 14-day-old male presenting with persistent anemia and hyperbilirubinemia was diagnosed with HS by increased red blood cell osmotic fragility and decreased fluorescence on the eosin-5′-maleimide binding test. For his failure to thrive and hypotonia, genetic sequencing revealed a de novo variant of the SPTB gene (p.Q1034X) on exon 15. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. A variant of uncertain significance (p.R438W) in the chondroitin sulfate synthase 1 (CHSY1) gene …

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

IMPORTANCE: In-hospital cardiac arrest (IHCA) is a significant public health burden. Rates of return of spontaneous circulation (ROSC) have been improving, but the best way to care for patients after the initial resuscitation remains poorly understood, and improvements in survival to discharge are stagnant. Existing North American cardiac arrest databases lack comprehensive data on the post-resuscitation period, and we do not know current post-IHCA practice patterns. To address this gap, we developed the Discover In-Hospital Cardiac Arrest (Discover IHCA) study, which will thoroughly evaluate current post-IHCA care practices across a diverse cohort.

OBJECTIVES: Our study collects granular data on post-IHCA …

Trifarotene Alleviates Skin Photoaging Injury By Inhibition Of Jnk/C-Jun/Mmps, Xuan Fei, Lele Zixin Yang, Jingjing Zhang, Xiang Li, Mengtian Pan, Guangchen Xu, Cuixia Zhang, Fei Liu, Weirong Fang

Student Papers, Posters & Projects

Long-term exposure to ultraviolet (UV) radiation induces skin photoaging, which manifests as oxidative stress, inflammation, and collagen degradation. Multiple approaches (topical or systemic retinoids, antioxidants, alpha-hydroxy acids, laser, surgery) are used in the treatment of photoaged skin, and the use of topical retinoids is currently a primary clinical treatment. Previous studies revealed that retinoic acid promotes keratinocyte proliferation and reduces melanin deposition and matrix metalloproteinase (MMP) secretion; it also causes potential allergic and inflammatory damage to the skin. This study aimed to investigate the therapeutic effects and mechanisms of trifarotene, a functional retinoic acid analog, on UV-irradiated photoaging ICR and …

We evaluate the impact of donor types on outcomes of hematopoietic cell transplantation (HCT) in myelofibrosis, using the Center for International Blood and Marrow Transplant Research registry data for HCTs done between 2013 and 2019. In all 1597 patients, the use of haploidentical donors increased from 3% in 2013 to 19% in 2019. In study-eligible 1032 patients who received peripheral blood grafts for chronic-phase myelofibrosis, 38% of recipients of haploidentical HCT were non-White/Caucasian. Matched sibling donor (MSD)-HCTs were associated with superior overall survival (OS) in the first 3 months (haploidentical hazard ratio [HR], 5.80 [95% confidence interval (CI), 2.52-13.35]; matched …

A 72-Year-Old Man With Acute Lung Injury And Anti-Melanoma Differentiation-Associated Gene 5 Antibody: A Case Report, Irakli Lemonjava, Jose Manuel Martinez Manzano, Sahar Sultan, Rekha Bhat, Corrado Minimo, Zurab Azmaiparashvili, Sadia Benzaquen

Einstein Health Papers

Anti-melanoma differentiation-associated gene 5 antibody (anti-MDA-5 Ab) is associated with amyopathic dermatomyositis (DM). These patients are particularly at high-risk for developing acute and rapidly progressive interstitial lung disease (ILD). Given the lack of muscle-related symptoms, along with its sudden onset and rapid clinical progression, the diagnosis of anti-MDA-5 Ab + ILD represents a challenge for clinicians. Even after the diagnosis is established, prognosis remains dismal owing to a hyperinflammatory state, mimicking cytokine storm, commonly refractory to potent immunosuppressive therapy. Hence, we present an elderly African American man who developed acute and rapidly progressive ILD in the setting of positive anti-MDA5 …

Endoscopic Transventricular "Inside-Out" Corpus Callosotomy: Illustrative Case, Michael Baumgartner, Elias Atallah, Kathleen Galligan, Pamela Mcdonnell, Benjamin Kennedy

Department of Neurosurgery Faculty Papers

BACKGROUND: Tonic and atonic "drop attack" seizures are a classic and morbid semiology in Lennox-Gastaut syndrome, resulting in frequent injuries and emergency room visits, in addition to neurocognitive sequelae. Recent years have seen a growing interest in less invasive techniques for performing the classic surgical treatment for drop attacks in Lennox-Gastaut syndrome, that is, corpus callosotomy.

OBSERVATIONS: A 5-year-old boy with Lennox-Gastaut syndrome presented for surgical evaluation. He experienced up to 20 daily tonic seizures despite multiple antiseizure medications. Preoperative imaging revealed highly abnormal anatomy with severe ventriculomegaly and thinning of the cortex and corpus callosum. Open microsurgery or an …

Division of Cardiology Faculty Papers

OBJECTIVES: To construct a new scoring system utilizing biomarkers, vitals, and imaging data to predict 30-day mortality in acute pulmonary embolism (PE).

BACKGROUND: Acute PE, a well-known manifestation of venous thromboembolic disease, is responsible for over 100,000 deaths worldwide yearly. Contemporary management algorithms rely on a multidisciplinary approach to care via PE response teams (PERT) in the identification of low, intermediate, and high-risk patients. The PESI and sPESI scores have been used as cornerstones of the triage process in assigning risk of 30-day mortality for patients presenting with acute PE; however, the specificity of these scoring systems has often come …

Minocycline-Induced Retinal Pigment Epithelium Hyperpigmentation Masquerading As Age-Related Macular Degeneration: Case Presentation And Proposed Mechanism, Michael D. Yu, Nikhil Bommakanti, Yoshihiro Yonekawa, Jose S. Pulido

Wills Eye Hospital Papers

PURPOSE: We describe the case of an 80-year-old man with bilateral minocycline-induced retinal pigment epithelium (RPE) hyperpigmentation, which initially masqueraded as AMD. Secondarily, using multimodal imaging features, we propose a mechanism for the development of minocycline-induced RPE hyperpigmentation.

OBSERVATIONS: The patient was referred with concern for AMD given the presence of macular drusenoid deposits on optical coherence tomography. However, funduscopic evaluation showed dense granular parafoveal hyperpigmentation, with a diffuse slate-colored hyperpigmentation throughout the peripheral fundus. Short-wavelength fundus autofluorescence of the macula disclosed no irregularities (as would be expected with drusen) while on near-infrared reflectance (NIR) imaging, numerous hyperreflective foci were …

Background

• Surgery is the primary form of definitive treatment for early-stage lung cancer.
• Poor lung function before surgery places patients at high risk of pulmonary complications after resection.
• Surgeons evaluate patient fitness for surgery using pulmonary function tests (PFTs) to calculate the predicted postoperative PFT (ppoPFT).
• Conventional ppoPFT calculations assume homogeneous lung function, which can be inaccurate.
• 4DCT-ventilation is a novel lung function imaging modality developed in radiation oncology that uses 4DCT data to calculate high-resolution ventilation maps.

Patel, Tsegaye Hailu Kumsa, Vishal A Patel, Selfu Girma, Benjamin K Stoff

SKMC Student Presentations and Publications

BACKGROUND: Cutaneous squamous cell carcinoma (cSCC) is the most common keratinocyte carcinoma in dark-skinned ethnic groups. Available studies are primarily focused on white populations, with fewer data available for black Africans, including Ethiopians. Therefore, less priority may be given to treatment and prevention in this population.

OBJECTIVE: To determine the prevalence and risk factors of cSCC among patients presenting to All Africa Leprosy, Tuberculosis, and Rehabilitation Training Center , Addis Ababa, Ethiopia.

METHODS: A literature review was performed to determine existing knowledge. A retrospective descriptive cross-sectional study was then conducted based on stored data of confirmed cases of cSCC from …

A Follow-Up To Implementing A Sizing Chart For Nasal Cannula Placement To Decrease Associated Pressure Ulcers In Infants, William F. Bucher, Rrt-Nps

Division of Pulmonary, Allergy, and Critical Care Medicine Posters

Background

The Joint commission definition of a “Pressure Ulcer” is a broader term that includes decubitus ulcers, but also includes any ulcerations associated with pressure. In 2015, over a three-month period, the Intensive Care Nursery (ICN) at Thomas Jefferson University Hospital had five patients who developed pressure ulcers due to placement of an improper size nasal cannula being used for that patient. Infant nasal cannulas are typically classified as being for micro premature, premature, neonate, infant, and intermediate infant size patients. To this day, there is no instruction by most manufactures for fitting a nasal cannula to the actual size …
