A Rare Sequela Of Untreated Streptococcus Pharyngitis: A Case Report., Meredith Hiltbrand Lehoe, Emily Cushing

Ambulatory and Primary Care Articles

Pharyngitis is commonly caused by the gram positive bacteria, streptococcus. Given the potential morbid complications of untreated streptococcal pharyngitis, antibiotics are critical. One of the rarer complications is pulmonary-renal syndrome (PRS), defined as rapidly progressive glomerulonephritis and diffuse alveolar hemorrhage. PRS is associated with high rates of morbidity and mortality, making swift diagnosis and treatment imperative for survival. More common causes of PRS are tied to autoimmune diseases. This case describes a novel progression of PRS caused by streptococcus. A 26-year-old male with no significant medical history presented to our emergency department with streptococcal group A-positive sore throat. After discontinuing …

Implementation Of A Tracheostomy Discharge Education Class For Nicu Nurses, Todd N. Chamoy

Doctor of Nursing Practice Final Manuscripts

Infants who are ventilator-dependent or have anatomic anomalies of their airway frequently require tracheostomy placement prior to discharge from the hospital in order to be cared for safely at home. At this large quaternary children’s hospital in Southern California, preparing these infants for discharge after tracheostomy placement has not been the role of the NICU nurse. There was no system in place on how to train caregivers, and the NICU staff felt unprepared. Evidence supports use of intensive educational programs to improve nurse knowledge and skills of tracheostomy care, allowing NICU nurses to provide improved care and pre-discharge teaching.

Sharma, John Ceremsak, Ryan H. Belcher, James D. Phillips, Jay A. Werkhaven, Amy S. Whigham, Lyndy J. Wilcox, Christopher T. Wootten, Frank W. Virgin, Jason S. Park

School of Medicine Faculty Publications

Objective: Evaluate the use of tranexamic acid (TXA) and observation as a management option for pediatric patients presenting with posttonsillectomy hemorrhage (PTH). Study Design: Retrospective analysis of a prospectively implemented quality improvement initiative with a historical control comparison group. Setting: Tertiary children's hospital. Methods: Patients < 18 years of age who underwent adenotonsillectomy (AT) and returned to the Emergency Department for PTH were included. Patients who were stable without large volume or active bleeding were given intravenous TXA and admitted for overnight observation. Data were compared in a before-and-after analysis: preprotocol (April 2022 to March 2023) versus postprotocol (April 2023 to March 2024). For cost-effectiveness analysis, we analyzed aggregated claims data from a commercial claims database. Results: Preprotocol 1800 adenotonsillectomies were performed, and 40 procedures were performed for control of hemorrhage (2.2 per 100 AT). Postprotocol 2356 adenotonsillectomies were performed, and 30 procedures were performed to control hemorrhage (1.3 per 100 AT) showing a significant reduction in return to the operating room (relative risk [RR] = 0.59, 95% confidence interval [CI] [0.358, 0.916], P-value.020). There were no reported adverse events attributable to TXA. An estimated 21 surgeries were avoided, and 26 additional patients were observed in the hospital during the postprotocol period, for an estimated net cost savings of $174,970. Conclusion: The implementation of a standardized TXA protocol significantly reduced the need for return to the operating room for PTH in pediatric patients, without complications and with net cost savings to the health care system.

Intertrial Coherence As A Measure Of Synchrony In Ocular Vestibular Evoked Myogenic Potentials And The Effect Of Gaze Angle, Sydney Brown

Dissertations, 2020-current

Ocular vestibular evoked myogenic potentials (oVEMPs) are produced by highly synchronous bursts of extraocular muscle activity in response to stimuli. These responses reflect utricular function and can be recorded using surface electromyography electrodes. Traditional analysis of oVEMPs is limited to time-domain waveform measurements, such as amplitude and latency of response peaks. Objective synchrony-based measures have not yet been applied to the analysis of oVEMPs, particularly in the comparison of synchrony across gaze angles. We followed the new time-frequency method of analysis developed by Clinard et al. (2022) that was successfully applied to cervical VEMPs to quantify response synchrony. Air-conducted oVEMPs …

Postoperative Caregiver Decision Regret Following Velopharyngeal Dysfunction Surgery, Rohit Nallani, Nathan Farrokhian, Meghan Tracy, Kevin Sykes, Jill M. Arganbright

Research Days

Background

Decision regret (DR) is a powerful factor in medical decision-making, particularly for surgical decisions which carry multiple risks, impact quality of life (QOL), and have uncertain outcomes. While prior studies have investigated caregiver DR after tonsillectomy and otologic surgery, there is a paucity of data assessing DR following pediatric otolaryngology procedures. The aim of this study is to measure DR following velopharyngeal dysfunction (VPD) surgery.

Methods

A cross-sectional survey study with chart review was performed of caregivers of children who had VPD surgery performed by a single surgeon at a tertiary children’s hospital. Demographic, medical, and surgical history were …

Department of Otolaryngology - Head and Neck Surgery Posters

Abstract

- There are four common treatment modalities for obstructive sleep apnea (OSA)

• CPAP, MAD, UAS, MMA

- Retrospective data was examined to compare efficacies between these treatments for patients treated with one of these four OSA therapies.

• Primary outcome: Mean disease alleviation (MDA) - calculated value based on improvement of AHI adjusted by compliance.
• Secondary outcomes: Patient reported outcome measures (PROMs) - ESS, PRAQ, SAQLI

- It was found that the greatest mean disease alleviation was found in patients who underwent MMA. PROMs showed the most significant improvement in daytime sleepiness (ESS) for MMA.

A Multimodal Intervention To Improve Treatment And Clinical Outcomes In Children With Recurrent Otitis Media, Daniel Courtaney

Evidence-Based Practice Project Reports

Acute otitis media is the number one cause for primary health care visits and antibiotic prescriptions in the pediatric population (El Feghaly & Jackson, 2023). Upwards of 27% of children experience multiple episodes of otitis media (OM) that meet recurrent otitis media (ROM) diagnosis criteria (Pelton & Marchisio, 2023). Guided by the Iowa Model (Iowa Model Collaborative, 2017), the project’s purpose was to implement a multimodal intervention to decrease recurrent OM and repeat clinic visits. A comprehensive literature search of 5 databases yielded 16 sources ranging from levels I-IV (Melnyk & Fineout-Overholt, 2023). Using the AGREE II and JBI Critical …

Artificial Intelligence-Based Virtual Staining Platform For Identifying Tumor-Associated Macrophages From Hematoxylin And Eosin-Stained Images, Arpit Aggarwal, Mayukhmala Jana, Amritpal Singh, Tanmoy Dam, Himanshu Maurya, Tilak Pathak, Sandra Orsulic, Kailin Yang, Deborah Chute, Justin A Bishop, Farhoud Faraji, Wade M Thorstad, Shlomo Koyfman, Scott Steward, Qiuying Shi, Vlad Sandulache, Nabil F Saba, James S Lewis, Germán Corredor, Anant Madabhushi

Faculty, Staff and Students Publications

Background: Virtual staining is an artificial intelligence-based approach that transforms pathology images between stain types, such as hematoxylin and eosin (H&E) to immunohistochemistry (IHC), providing a tissue-preserving and efficient alternative to traditional IHC staining. However, existing methods for translating H&E to virtual IHC often fail to generate images of sufficient quality for accurately delineating cell nuclei and IHC+ regions. To address these limitations, we introduce VISTA, an artificial intelligence-based virtual staining platform designed to translate H&E into virtual IHC.

Methods: We applied VISTA to identify M2-subtype tumor-associated macrophages (M2-TAMs) in H&E images from 968 patients with HPV+ oropharyngeal squamous cell …

Case Report: Haemophilus Influenzae Meningitis In A 65 Year Old Female, Kaywan Saed, Russell Mordecai

Rowan-Virtua Research Day

We report a case of a 65-year-old female who presented with fever, altered mental status, and neck stiffness. Cerebrospinal fluid (CSF) analysis confirmed Haemophilus influenzae meningitis. The differential diagnosis of bacterial meningitis in older adults is broad and includes Streptococcus pneumoniae, Neisseria meningitidis, Listeria monocytogenes, and Haemophilus influenzae. However, in the post-Hib vaccine era, non-typeable H. influenzae has emerged as a significant cause of invasive disease in older adults, particularly in those with underlying comorbidities.

Older patients often present with atypical symptoms, which may delay diagnosis and treatment. In this case, early recognition and prompt administration of empiric antibiotic therapy …

The Impact Of Biomaterial Characteristics On Macrophage Phenotypes In Tissue Engineering: A Review, Julian Jackson, Hani Samarah, William Palmer, Zachary Kaplan, Marianna Nicodem, Parvesh Kumar, Spenser Short, Kelly Bridgham, Larry Harshyne, Joseph Curry

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Macrophages are highly plastic cells central to pathogen removal, tissue regeneration, and inflammation, making them key targets in biomaterial design for improved clinical outcomes. Foreign body responses (FBRs) to implanted biomaterials often involve excessive macrophage-mediated inflammation, leading to fibrotic encapsulation, infection, and implant failure. Advances in tissue engineering demonstrate that macrophage polarization - the transition from pro-inflammatory M1 to anti-inflammatory M2 phenotypes - can be influenced by biomaterial properties to mitigate these responses and enhance regeneration. This review synthesizes the relationship between biomaterial properties, such as surface chemistry, structure, and stiffness, and their ability to modulate macrophage behavior. Key innovations, …

Faculty, Staff and Student Publications

Background: Exposomes are critical drivers of carcinogenesis. However, how they modulate tumor behavior remains unclear. Extensive clinical data show cigarette smoke to be a key exposome that promotes aggressive tumors, higher rates of metastasis, reduced response to chemoradiotherapy, and suppressed anti-tumor immunity. We sought to determine whether smoke itself can modulate aggressive tumor behavior in head and neck squamous cell carcinoma (HNSCC) through reprogramming of the cellular reductive state.

Methods: Using established human and murine HNSCC cell lines and syngeneic mouse models, we utilized conventional western blotting, steady state and flux metabolomics, RNA sequencing, quantitative proteomics and flow cytometry to …
