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.


Rethinking Congenital Cytomegalovirus: A Narrative Review Of The Clinical, Public Health, And Ethical Challenges Of A Preventable Cause Of Childhood Hearing Loss, M. Peyton Simons, Gauri Mankekar 2025 LSU Health Sciences Center - New Orleans

Rethinking Congenital Cytomegalovirus: A Narrative Review Of The Clinical, Public Health, And Ethical Challenges Of A Preventable Cause Of Childhood Hearing Loss, M. Peyton Simons, Gauri Mankekar

School of Medicine Faculty Publications

Congenital cytomegalovirus (cCMV) is the most common non-genetic cause of pediatric sensorineural hearing loss, affecting approximately tens of thousands of infants annually in the United States. While cCMV may present symptomatically at birth, many infants are asymptomatic initially and later develop progressive or fluctuating hearing loss, which is often undiagnosed without early screening. Despite advances in diagnostic methods such as polymerase chain reaction (PCR) testing, the absence of a national screening policy in the U.S. results in significant variability in early detection and follow-up care. This narrative review provides an overview of the clinical manifestations, diagnostic strategies, and treatment options …

Chronic rhinosinusitis (CRS) affects quality-of-life (QoL) in people with cystic fibrosis (PwCF), despite the reduction in symptoms and symptom severity associated with cystic fibrosis transmembrane conductance regulator (CFTR) modulators [1]. To precisely assess sinus symptoms and treatment needs in the post-modulator period, patient-related QOL instruments should be revisited. The 22-item SinoNasal Outcome Test (SNOT-22) measures CRS burden and QoL. Abbreviated surveys can lessen respondent fatigue. Item response theory (IRT) can help refine surveys by identifying the most informative survey items while maintaining reliability [2–4]. IRT assesses item discrimination (ɑ), the ability to differentiate trait levels, and difficulty (β), which defines …

It is estimated that 1 in every 200 US newborns has congenital cytomegalovirus (cCMV). Delayed identification of cCMV in newborns precludes timely intervention to mitigate sequelae of the infection such as hearing loss and other neurological complications. Newborn testing for cCMV enables appropriate diagnosis and intervention by multidisciplinary teams to properly manage the immediate sequelae of cCMV, avoid unnecessary additional testing that can result from delayed diagnosis, and monitor for future complications. It is the position of the American Cochlear Implant Alliance, the National CMV Foundation, and the American Academy of Otolaryngology-Head and Neck Surgery that universal newborn cCMV screening …

Faculty, Staff and Student Publications

Background: Human papillomavirus (HPV)-driven cancers include head and neck squamous cell carcinoma and cervical cancer and represent approximately 5% of all cancer cases worldwide. Standard-of-care chemotherapy, radiotherapy, and immune checkpoint inhibitors (ICIs) are associated with adverse effects and limited responses in patients with HPV-driven cancers. The integration of targeted therapies with ICIs may improve outcomes. In a previous study, we demonstrated that Aurora kinase A (AURKA, Aurora A) inhibitors lead to apoptosis of human HPV-positive cancer cells in vitro and in vivo. Here, we explored the potential of Aurora A inhibition to enhance response to ICIs in immune-competent …

Gain-Of-Function Tp53 Mutations Induce Non-Canonical Nf-Κb Transcriptional Targets To Promote Tumor Development, Kelsey A. Yutan 2025 Scripps College

Gain-Of-Function Tp53 Mutations Induce Non-Canonical Nf-Κb Transcriptional Targets To Promote Tumor Development, Kelsey A. Yutan

Scripps Senior Theses

Background: Gain-of-function TP53 mutations have previously been shown to induce chromosomal instability (CIN) in cancer cells, triggering the cGAS-STING innate immune response and subsequently activating the non-canonical NF-κB (NC-NF-κB) signaling pathway. This signaling cascade promotes cancer cell metastasis and an immunosuppressive tumor microenvironment (TME), significantly impacting tumor development and progression. However, the precise downstream mechanisms by which the mutp53-CIN-cGAS-STING-NC-NF-κB signaling pathway facilitates tumor development and progression remain poorly understood. Here, our objective was to identify direct downstream targets of mutp53-CIN-cGAS-STING-induced NC-NF-κB signaling that potentially impact the TME to promote the development and progression of oral squamous cell carcinoma.

Acute Exacerbations Of Chronic Rhinosinusitis, Robert M. Frederick, Kent Lam, Joseph K. Han 2025 Macon & Joan Brock Virginia Health Sciences at Old Dominion University

Acute Exacerbations Of Chronic Rhinosinusitis, Robert M. Frederick, Kent Lam, Joseph K. Han

Department of Otolaryngology (ENT) Faculty Publications

Purpose of Review

We aim to highlight recent advancements on the evolving chronic rhinosinusitis (CRS) phenotype: acute exacerbations of chronic rhinosinusitis (AECRS). We focused on studies that expanded the current understanding of its pathophysiology, patient characteristics, and disease burden.

Recent findings

Defining AECRS has been a topic of discussion for many years. A recent regulatory definition of AECRS in the literature incorporates a > 3 day requirement of worsened symptoms and an escalation of treatment. It is important not to rely on patient-reported rescue medication frequency as it was recently demonstrated these are only obtained for 1/3 of reported AECRS episodes. …

Semi-Automated Virtual Endoscopy Of The Frontal Recess, Ali Jafar, William Yao, Martin Citardi

Faculty, Staff and Student Publications

Introduction: Virtual endoscopy (VE) is the computer-based reprocessing of diagnostic imaging to simulate endoscopy of an anatomic region of interest. VE of the Frontal Sinus Outflow Tract (FSOT) may assist surgical planning and education.

Method: VE was performed on 16 normal sinus computed tomography (CT) scans for a total of 32 sides using the "path-to-target" tool on the TruDi surgical navigation system (ver. 2.3; Acclarent, Irving, CA, USA). To aid orientation during VE, planning points were placed on the middle turbinate, ethmoidal bulla, and skull base. The VE representation of anatomy and FSOT accuracy was manually confirmed by reviewing the …

Faculty, Staff and Student Publications

Introduction: Although surgical navigation is commonly used in rhinologic surgery, data on real world performance are sparse because of difficulties in collecting measurements for target registration error (TRE). Despite publications showing submillimeter TRE, surgeons do report TRE of >3 mm. We describe a novel method for assessing TRE during surgery and report findings with this technique.

Methods: The TruDi navigation system (Acclarent, Irving, CA) was registered using a contour-based protocol. The surgeon estimated target registration error (e-TRE) at up to 8 points (anatomic regions of interest [ROI]) during endoscopic sinus surgery (ESS). System logs were used to simulate the localization …

Faculty, Staff and Student Publications

Background and purpose: Prior work on adaptive organ-at-risk (OAR)-sparing radiation therapy has typically reported outcomes based on fixed-number or fixed-interval re-planning, which represent one-size-fits-all approaches and do not account for the variable progression of individual patients' toxicities. The purpose of this study was to determine the personalized optimal timing of re-planning in adaptive OAR-sparing radiation therapy, considering limited re-planning resources, for patients with head and neck cancer (HNC).

Materials and methods: A novel Markov decision process (MDP) model was developed to determine optimal timing of re-planning based on the patient's expected toxicity, characterized by normal tissue complication probability (NTCP), for …
