North Texas GME Research Forum 2026

Peri-partum infective endocarditis (IE) is a rare but serious condition with high maternal and fetal morbidity and mortality. IE is exceedingly uncommon in young healthy patients, especially without any known risk factors such as intravenous (IV) drug use, congenital heart disease, or rheumatic heart disease. IE is estimated to complicate 0.00002% of in-hospital deliveries. Similar to the general population, staphylococcal and streptococcal species remain the most common pathogens in obstetric patients. Enterococcal species make up less than 10% of IE cases in pregnant women. Very few cases of enterococcal IE in the post-partum period are reported in the literature. We …

An Unusual Source Of A Lethal Pathogen: Paeniclostridium Sordellii Bacteremia In Acute Cholecystitis, Myrna Garcia, Leena Algarin, Olutoyin Abitoye, Rachel Gnanaprakasam

North Texas GME Research Forum 2026

Paeniclostridium sordellii is a spore-forming, gram-positive, anaerobic bacilli known for its highly virulent toxin production, often leading to fulminant sepsis and shock. It is most commonly associated with gynecologic infections and necrotizing soft tissue infections associated with intravenous drug use. However, reports of P. sordellii bacteremia in the setting of gall bladder infections are quite rare. This case report highlights an unusual presentation of P. sordellii infection with bloodstream infection originating from acute cholecystitis, demonstrating a non-fulminant clinical course and successful treatment with ceftriaxone.

A Hidden Culprit: Disseminated Tuberculosis Masquerading As Abdominal Abscesses, Sudiksha Veerareddy, Alex Hall, Urvi Sakhuja, Sarah Abuelayyan, Evangelista Ezenduka, Rinu Varghese

North Texas GME Research Forum 2026

Introduction: Tuberculosis (TB) is an insidious pulmonary infection that is most prevalent in developing countries. Primary TB may also become latent after initial infection and remain dormant in the body until the patient becomes immunocompromised. The infection will then resume and can become disseminated, moving hematogenously and through the lymphatics to other areas of the body. Disseminated TB is known to manifest in a variety of ways, making it difficult to diagnose.

Case Presentation: A 28-year-old- male patient presented to Medical City Arlington with complaints of left lower quadrant abdominal pain. He immigrated from Cameroon 4 years prior. Initial CT …

Extra-Intestinal Clostridioides Difficile Abscess In A Small Bowel Gist: A Rare Tumor-Associated Complication, Nicholas Gerden, Pradip Gautam, Asad Rehman, Long Hoang

North Texas GME Research Forum 2026

Extra-intestinal infections caused by Clostridioides difficile are exceedingly rare and typically occur in settings that disrupt the gastrointestinal barrier, including recent gastrointestinal surgery, bowel perforation or microperforation, and severe colonic disease.

We present the case of a 75-year-old man with abdominal pain and hemoperitoneum in the setting of a suspected small bowel leak secondary to an intestinal mass. Computed tomography angiography revealed an 11.0 × 9.6 cm pelvic fluid collection, prompting exploratory laparotomy with drainage of a pelvic abscess and evacuation of hemoperitoneum. Intraoperatively, a small bowel perforation caused by a 4.4 cm gastrointestinal stromal tumor (GIST) was identified. Operative …

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 …

Cytomegalovirus As A Potential Trigger For Acute Coronary Syndrome: A Case Of Nstemi In A Previously Healthy Patient, Hussam Al Hennawi, Muhammad Sabri, David Teng, Maxwell Berman, Botros Shenoda

Abington Jefferson Health Papers

Cytomegalovirus (CMV) infection has been implicated in endothelial dysfunction and atherogenesis, yet its role as a potential trigger for acute coronary syndrome (ACS) remains underrecognized. We present a case of a 32-year-old male with no prior medical history who developed non-ST elevation myocardial infarction (NSTEMI) and was subsequently found to have active CMV infection. The patient had no known history cardiovascular disease, though subsequent testing did reveal additional underlying risk factors. This case highlights the need to consider infectious etiologies, including CMV, as contributors to ACS in young, otherwise apparently healthy individuals. Understanding the interplay between viral infections and atherosclerotic …

Extensive Superficial Dermatomycosis Caused By Cladophialophora Sp., A Deep Mycosis Pathogen: A Case Report, Nikko Vanda Limantara, Agnes Sri Siswati, Flandiana Yogianti

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Superficial dermatomycosis, predominantly caused by dermatophytes, affects approximately 20–25% of the global population. However, non-dermatophytic fungi, such as Cladophialophora species (sp.), can also cause similar cutaneous infections. Although less common, these organisms are particularly concerning in immunocompromised individuals.

Case Illustration: A 66-year-old immunocompromised male presented with widespread pruritic and erythematous patches, initially misdiagnosed as tinea corporis. Despite receiving standard antifungal therapy, his condition persisted. Further investigation through fungal culture identified Cladophialophora sp., which was resistant to common antifungal agents such as fluconazole, itraconazole, and ketoconazole. However, the fungus was sensitive to terbinafine, which has …

Infective Endocarditis And Meningitis In A Healthy Newborn Without Underlying Heart Disease, Due To Streptococcus Agalactiae - A Case Report., Dalal Siddig Idris, Muath Mohammed Al Ghamdi, Maria Laura Bellovalls, Mohammed Fararjeh

Journal of the Saudi Heart Association

Streptococcus Agalactiae endocarditis is a rare clinical entity in newborns with a normal structured heart. It is generally characterized by acute onset, the presence of large vegetations, rapid valvular destruction and frequent complications, particularly embolization. Mortality is high with medical therapy alone. We are reporting a rare case of infective endocarditis (IE) with mitral valve vegetation in a 9-day old healthy newborn following Streptococcus Agalactiae sepsis, complicated by meningitis and micro-abscesses. Mitral valve (MV) vegetation was removed surgically; the patient received intravenous antibiotics for six weeks. Transthoracic echocardiography after surgery showed severe MV regurgitation and severe pulmonary hypertension which was …

Implementing A Sepsis Questionnaire To Reduce Readmissions…A Health Plan’S Experience, Vernita L. Kelley

All Doctor of Nursing Practice (DNP) Scholarly Projects

Problem: Sepsis is a life-threatening condition with high readmission risk, threatening patient recovery and survival. In the managed care organization (MCO) where this DNP project was implemented, sepsis ranks among the top five readmission diagnoses. The organization's 30-day readmission rate of 15.5% is substantially higher than the benchmark of 9.29%, highlighting a clinical quality issue, a strain on patient outcomes, and a strain on healthcare resources.

Aim of the Project: This quality improvement (QI) project aimed to reduce sepsis readmissions by embedding a sepsis questionnaire into case management workflows to identify clinical risks and social determinants of health, improve transitions, …

Bilateral Small Vessel Strokes In A Young Male With Coccidioidal Meningitis And Suspected Cns Vasculitis, Hugo Zamarron, Ahsan Ali

Research Colloquium

Background: Cerebral small vessel strokes in young, otherwise healthy adults without traditional vascular risk factors are rare and warrant further investigation. Central nervous system (CNS) vasculitis is an uncommon etiology that may be triggered by infections, including fungal pathogens. This case is notable for a suspected primary CNS vasculitis manifesting as bilateral deep infarcts in the setting of Coccidioidal meningitis. It highlights the importance of considering fungal infections and vasculitis in the differential diagnosis of stroke in younger patients.

Case Presentation: A 32-year-old previously healthy male presented with fever, headache, and was diagnosed with aseptic meningitis. He was later readmitted …

Background. Bacterial vaginosis (BV) is a vaginal dysbiosis characterized by polymicrobial communities of BV-associated bacteria (BVAB) adhered to the vaginal epithelium. Despite decades of research, its etiology remains unknown. We aimed to investigate BV biofilm formation over time among women who developed incident BV (iBV) using peptide nucleic acid-fluorescence in situ hybridization (PNA-FISH), focusing on 3 key BVAB (Gardnerella species, Prevotella bivia, and Fannyhessea vaginae). Methods. Heterosexual, nonpregnant women ages 18–45 with optimal vaginal microbiota were enrolled to self-collect twice-daily vaginal specimens for 60 days. iBV was defined as a Nugent score of 7–10 on ≥ 4 consecutive specimens. For …

Synergistic Cefiderocol-Containing Antibiotic Combinations Active Against Highly Drug-Resistant Acinetobacter Baumannii Patient Isolates With Diverse Resistance Mechanisms, Justin Halim, Andrew P. Keane, Jeannete Bouzo, Tope Aderibigbe, Jessica A. Chicola, Katie T. Nolan, Keertana Jonnalagadda, Jason X. Tran, Valerie J. Carabetta

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Acinetobacter baumannii is a nosocomial pathogen known for rapidly developing resistance to nearly all antibiotics, including last-line agents. Cefiderocol, a novel siderophore cephalosporin, has shown in vitro activity against A. baumannii and is now used clinically, but resistance is emerging. Data on cefiderocol-based antibiotic combinations are limited.

OBJECTIVES: To evaluate the in vitro activity of cefiderocol alone and in combination with other antibiotics against XDR and PDR A. baumannii clinical isolates, and to explore resistance mechanisms underlying cefiderocol synergy.

METHODS: We tested 21 XDR/PDR clinical isolates and one NDM-1-producing strain using broth microdilution and checkerboard assays with cefiderocol and …

Fatal Facial Necrotizing Fasciitis: A Case Report Highlighting Diagnostic And Therapeutic Challenges, Muhammad Sheraz Hameed, Syed Rafay Hussain Zaidi, Ali Iqbal, Muhammad Ahsan, Austin Mitchell, Azka Asad Mirza, Joshiah Gordon, Rahmat Gul Omarzai

Department of Medicine Faculty Papers

BACKGROUND: Facial Necrotizing Fasciitis (FNF) is a rare but aggressive, life-threatening infection involving the face's subcutaneous tissues and underlying musculature. It can rapidly progress to septic shock and multi-organ failure if not promptly recognized and treated. The clinical course, including severe pain, disproportionate tenderness, and systemic signs, is often the most crucial factor in diagnosis. While computed tomography (CT) can aid in identifying early signs such as soft tissue swelling and gas formation, clinical suspicion remains paramount and should not be delayed by reliance on imaging alone. Without early intervention, FNF may lead to devastating outcomes, including disfigurement, blindness, or …
