Stop The Bleed! Acute Epistaxis Management, Christopher R. Cannell 2025 South Shore Health

Stop The Bleed! Acute Epistaxis Management, Christopher R. Cannell

Lynchburg Journal of Medical Science

Epistaxis, the most common Otolaryngology-related emergency, is responsible for one in 200 emergency department (ED) visits in the United States (US) and one-third of otolaryngology visits.1,11 Up to 60% of the population will experience epistaxis during their lifetime, and 6% -10 % will require medical intervention.2,3 Epistaxis occurs in children and adults and has a seasonal variation. Although 85% of nosebleeds are idiopathic, they are more frequent in those on supplemental oxygen, anticoagulation, antiplatelet therapy, and in those with other conditions that may predispose them to bleeding. Most clinicians will encounter patients with acute epistaxis; therefore, it is …


Testosterone Replacement Therapy In The Middle-Aged Male, Gina N. DeMilt 2025 University of Lynchburg

Testosterone Replacement Therapy In The Middle-Aged Male, Gina N. Demilt

Lynchburg Journal of Medical Science

The purpose of this review was to investigate the use of testosterone supplementation in the middle-aged male with a focus on the pathophysiology of testosterone throughout the lifespan, current supplementation options and their adverse effects, and the overall benefit of supplementing to enhance quality of life. A comprehensive search of electronic databases was conducted identifying studies that assessed clinical outcomes, pathophysiology, supplementation options, adverse effects and benefits of treatments. The findings suggested that testosterone levels naturally decline with age with most men developing symptoms of hypogonadism around age 60. Testosterone supplementation outside of current guidelines is not recommended, however men …

Intraoperative Code Status: Moving From Misinformation To Respect For Patient Autonomy, Jacob Applegarth, Jacob M. Morton, Nathan M. Novotny, Ngan Nguyen, Abram Brummett

Conference Presentation Abstracts

Introduction: Intraoperative code status represents a complicated topic for patients and providers. Prior studies demonstrated a lack of understanding of intraoperative code status, specifically do not resuscitate (DNR) orders. This misunderstanding appears common despite clear professional recommendations. A recent survey of surgery residents at our institution showed variability in understanding of intraoperative code status policy despite clear institutional guidelines. Few studies utilized simulated education for surgeons and surgical residents to navigate intraoperative DNR status. This project aims to create a simulation-based program for residents to navigate intraoperative DNR status ethically and to assess its impact on learning, practice patterns and …

BACKGROUND: Scalable identification of patients with post-acute sequelae of COVID-19 (PASC) is challenging due to a lack of reproducible precision phenotyping algorithms, which has led to suboptimal accuracy, demographic biases, and underestimation of the PASC.

METHODS: In a retrospective case-control study, we developed a precision phenotyping algorithm for identifying cohorts of patients with PASC. We used longitudinal electronic health records data from over 295,000 patients from 14 hospitals and 20 community health centers in Massachusetts. The algorithm employs an attention mechanism to simultaneously exclude sequelae that prior conditions can explain and include infection-associated chronic conditions. We performed independent chart reviews …

Case Report: Oral Contraceptives-Induced Cholestasis, Aura Calderon, Taiwo Ajani, Nayiri Derian, Catherine Matos, Ivan Mogollon, Andres Suarez 2025 The University of Texas Rio Grande Valley

Case Report: Oral Contraceptives-Induced Cholestasis, Aura Calderon, Taiwo Ajani, Nayiri Derian, Catherine Matos, Ivan Mogollon, Andres Suarez

Research Symposium

Background: Oral contraceptives represent one of the most prevalently utilized pharmacological interventions for contraception, renowned for their safety and efficacy. However, their advantageous safety profile, these pharmaceuticals are intermittently correlated with infrequent yet significant hepatobiliary complications, including drug-induced cholestasis and hyperbilirubinemia1. The estrogenic constituents of oral contraceptives are recognized for their capacity to disrupt bile acid transport within the hepatic system, culminating in intrahepatic cholestasis2. This phenomenon is particularly alarming in individuals possessing inherent genetic susceptibilities, such as Dubin-Johnson Syndrome, wherein bilirubin metabolism and excretion are already adversely affected3. The identification and comprehension of these adverse effects are imperative for …

An Endocrine Enigma: The Implications Of Pembrolizumab Therapy, Miguel A. Lopez, Mario Trujillo Acosta, Jose Romero Villarreal Calderon, Laura Garcia

Research Symposium

Disorders of the endocrine system are a potential complication of cancer treatment despite newer immunotherapy agents holding promise to improve patient outcomes. Breast cancer in particular requires pharmacologic intervention based on the receptor positivity. For example, a triple negative workup often requires neoadjuvant therapy with the newer immunotherapy agent pembrolizumab. Clinicians should be aware of the potential adverse effects of this drug, most notably adrenal insufficiency. This case follows a 52 year old hispanic female patient with a history of triple negative left sided breast cancer on immunotherapy with pembrolizumab, who presented to the emergency department after a syncopal episode …

Cancer Of Unknown Primary With Squamous Cell Carcinoma Phenotype Presenting As Isolated Axillary Mass, Nicole Liang, Mohamed Ashal, Lynne J. Goebel

Internal Medicine

Cancer of unknown primary (CUP) is a rare metastatic malignancy where no primary tumor can be found. We report the case of a 71-year-old female with a strong family history of breast cancer presenting with isolated axillary lymphadenopathy after a tick bite. A biopsy of the axillary mass revealed poorly differentiated squamous cell carcinoma and after extensive evaluation, she was diagnosed with metastatic squamous cell carcinoma with unknown primary tumor. We present this case because of the role of confounding history complicating her initial diagnosis and bringing awareness to a rare disease.

A Peculiar Pancreatitis: Investigating The Adverse Effects Of Mesalamine, Elias Arellano Villanueva, Miguel Lopez, Alhasan Asaad, Jose Campo Maldonado

Research Symposium

Background: Acute pancreatitis (AP) is a leading cause of gastrointestinal-related hospitalizations in the United States, accounting for approximately 300,000 emergency department visits annually. It is characterized by parenchymal and peripancreatic fat necrosis accompanied by inflammation. The clinical diagnosis of AP is based on elevated serum amylase and lipase levels, characteristic imaging findings, and epigastric pain often radiating to the back. While gallstones and alcohol use are the most common causes of AP, drug-induced pancreatitis (DIP) is a rare but increasingly recognized etiology, contributing to 0.1–5% of cases. DIP is typically diagnosed by excluding other causes and is often associated with …
