A Case Report Of Mesalazine-Induced Pulmonary Injury In A Patient With Ulcerative Colitis, Vasileios Paraschou, Vasileios Papavasileiou, Ilektra Voulgareli, Vasilios Tzilas

HCA Healthcare Journal of Medicine

Introduction

Mesalazine (5-aminosalicylic acid) is widely used as a first-line therapy for ulcerative colitis (UC) due to its efficacy and safety profile. Rarely, it can cause pulmonary toxicity with variable clinical and radiologic manifestations, making diagnosis challenging.

Case Presentation

We report the case of a 52-year-old woman with UC who developed persistent fever and progressive exertional dyspnea following escalation of mesalazine dosage. Imaging revealed diffuse bilateral ground-glass opacities, while infectious and UC-related pulmonary causes were excluded. Pulmonary function testing demonstrated restriction and markedly reduced diffusing capacity. Following mesalazine discontinuation and initiation of corticosteroid therapy, the patient experienced rapid symptomatic, functional, …

Optimizing Antibiotic Strategies With A Clinical Pathway Approach: Enhanced Initiation And De-Escalation In Community-Acquired Pneumonia, Ahmad Behzadpour

HCA Healthcare Journal of Medicine

Background

Community-acquired pneumonia (CAP) remains a leading cause of hospitalization, mortality, and health care expenditure worldwide. Inappropriate use of broad-spectrum antibiotics contributes to antimicrobial resistance, adverse drug events, and increased costs. Antibiotic stewardship and standardized clinical pathways are key strategies to improve prescribing practices.

Methods

This quality improvement (QI) initiative was conducted at a 240-bed tertiary care teaching hospital from January 2023 through January 2025. A CAP-specific digital clinical pathway was developed using Curbside Health® and integrated into the electronic health record (EHR), accessible through a structured order set to support real-time clinical decision-making. The intervention included provider education and …

Hemoptysis And Shock From A Proximal Bronchial Artery Aneurysm Successfully Treated With Endovascular Embolization, Gautham Raghuthaman, Charmi Mehta, Tamer Hudali

North Texas GME Research Forum 2026

Background: Bronchial artery aneurysm (BAA) is a rare vascular abnormality and an uncommon cause of hemoptysis. Although many BAAs are asymptomatic, rupture can result in life-threatening hemorrhage and shock. Proximal BAAs arising near the bronchial artery origin are particularly rare and may be underrecognized due to nonspecific clinical and radiographic findings.

Case Presentation: Patient is a 49-year-old male with a history of pituitary tumor resection complicated by secondary adrenal insufficiency and hypothyroidism presented with three days of cough, fatigue, and hemoptysis. He was hypotensive and hypoxic on arrival and required vasopressor support with stress-dose corticosteroids. Computed tomography angiography (CTA) of …

Challenges Of Thrombectomy In Submassive Pulmonary Embolism With Patent Foramen Ovale, Sana Khan, Syed Ahmed, Muhammad T. Siddique, Edic Stephanian

North Texas GME Research Forum 2026

BACKGROUND/ INTRODUCTION: Submassive, or intermediate-risk, pulmonary embolism (PE) is defined by preserved systemic blood pressure with evidence of right ventricular (RV) strain. The presence of a patent foramen ovale (PFO) in this setting significantly increases the risk of hypoxemia, paradoxical embolization, and procedural complications during catheter-based interventions. Mechanical thrombectomy has become an important treatment option for selected patients with intermediate- to high-risk PE; however, experience in patients with concomitant large PFOs remains limited.

CASE PRESENTATION: A 78-year-old woman presented with acute dyspnea, hypoxemia, and chest pain and was found to have a saddle PE with severe RV dilation and biomarker …

Roles Of Thyroid Stimulating Hormone (Tsh) And Vitamin D Levels In Asthma Severity And Length Of Stay, Kumail Rizvi, Kenny Tran, Michele Mccarrol, Mohan Sengodan

North Texas GME Research Forum 2026

Background: Asthma exacerbations leading to hospitalization are very common and result from multifactorial causes. This research aims to investigate factors such as thyroid-stimulating hormone (TSH) and Vitamin D, which may play a role in the modulation of asthma-related hospitalizations and patient outcomes. TSH influences numerous cellular processes in the body, particularly during times of stress and illness, yet its role in asthma exacerbations and hospital length of stay remains unclear. Vitamin D has been studied for its role in enhancing medication absorption and regulating immune function, and multiple studies have shown that low serum Vitamin D levels are associated with …

Don’T Blame The Heart When On Steroids: A Rare Case Of Glucocorticoid Dependant Childhood Asthma Causing Non-Ischemic Dilated Cardiomyopathy, Greeshma Molugu, Srinivasan Rajaganapathy, Machaiah Madhrira, Karthik Anand

North Texas GME Research Forum 2026

Background: Steroids are known to have various cardiac side effects, such as hypertension, left ventricular hypertrophy, myocardial infarction, and sudden cardiac death. They are also known to cause rare but potentially life-threatening cardiomyopathy. The mechanisms behind steroid-induced cardiomyopathy are multifactorial, potentially involving direct or indirect myocardial toxicity, such as tissue fibrosis, apoptosis, and alterations in cardiac remodeling pathways via the renin-angiotensin-aldosterone system. Cardiomyopathy is known to occur with anabolic steroid use, but the literature on glucocorticoid-induced cardiomyopathy is scant. We present a rare case of glucocorticoid-induced dilated cardiomyopathy(DCM) in a patient with a history of refractory asthma who was treated …

Invasive Pulmonary Aspergillosis: A Two-Year Journey, Jason Woods, Padmaditya Sureddi, Nga Van, Danielle Ford

North Texas GME Research Forum 2026

BACKGROUND: Highly active anti-retroviral therapy (HAART) has decreased the incidence of opportunistic infections among persons with HIV. Invasive aspergillosis specifically is uncommon among individuals with clusters of differentiation 4 (CD4) count >100 cells/mm3. Furthermore, treatment of aspergillosis in the HIV-infected population has not been examined systematically. We report a patient with CD4 count >200 cells/mm3, compliant with HAART therapy who developed invasive pulmonary aspergillosis (IPA) over the course of two years that was successfully treated through a combination of bronchial artery embolization and liposomal amphotericin.

CASE PRESENTATION: A 56-year-old man from southern Africa with four-year history of HIV-1 on HAART …

Reducing Respiratory Viral Testing In A Pediatric Emergency Department: A Quality Improvement Initiative, Anna Suessman

North Texas GME Research Forum 2026

Background: Respiratory viral testing in pediatric emergency departments (EDs) is frequently performed despite limited impact on clinical management for many low-risk presentations. Unnecessary testing increases cost and operational burden may delay patient throughput and can provide false reassurance to caregivers. Additionally, pediatric emergency department nurses agreed with overburden and impact to throughput based on overuse of viral testing (qualitative nursing survey conducted on September 4, 2024 showed >98% felt testing was unnecessary). We hypothesized that reducing testing through standardized team education and discharge processes would not negatively affect patient experience. This initiative aimed to decrease unnecessary respiratory viral testing during …
