A Budding Pancreatic Mass: A Review Of Disseminated Blastomycosis, Tina C. L. Phan, Chloe N. Hundman, Neena Thomas-Gosain, Christopher D. Jackson

Journal of Community Hospital Internal Medicine Perspectives

A 67-year-old male patient presented with anorexia, weight loss, skin masses, and flank pain over the past three months. Imaging revealed a lung mass and a cystic lesion in the pancreatic head. After initial diagnostic work-up and clinical deterioration, broad based budding, seen on pathology, led to a diagnosis of disseminated blastomycosis. After receiving a 14-day course of liposomal amphotericin B followed by itraconazole, the patient showed significant clinical improvement. We reviewed all disseminated blastomycosis cases in the medical literature involving gastrointestinal organs. Although pancreatic involvement is rare, we suggest that it should be suspected in those with a rapidly …

Evaluation Of Human Mesenchymal Stromal Cells (Msc) As An Adjuvant Therapeutic For Chronic Lyme Disease, Matthew Teryek

Rowan-Virtua Research Day

Background: Lyme disease, caused by the spirochetal bacterium Borrelia burgdorferi, is the most prevalent vector-borne illness in the Northern Hemisphere. If undiagnosed or untreated, the disease progresses through multiple stages of increasing clinical severity. While antibiotics such as doxycycline and ceftriaxone are the current standard of care, patients with chronic or late-stage Lyme disease may require additional therapeutic interventions.

Rationale: Human mesenchymal stem cells (MSCs) are of growing clinical interest due to their immunomodulatory properties, low immunogenicity, and potential to promote tissue repair. These characteristics position MSCs as promising adjuvant therapies for chronic Lyme disease, with the potential to …

Rowan-Virtua Research Day

The advent of immunomodulatory therapies and their ever-expanding number of treatment indications necessitates the understanding of their associated complications. Neutropenic fever serves as an example of these complications often encountered in clinical practice. Although neutropenic fever can result from virtually any pathogen, episodes of the syndrome secondary to tick-borne illness remain relatively undocumented in the scientific literature. In the case presented, a 77-year-old female with a pertinent past medical history of smoldering IgG multiple myeloma on active immunosuppressive therapy presented with a first-time episode of neutropenic fever likely secondary to tick-borne illness. Through this overview of a broader report, attention …

An Unusual Cause Of Sepsis: Capnocytophaga Canimorsus, Capnocytophaga, Christopher Dellmyer, Kishan B. Patel

Rowan-Virtua Research Day

Septic shock can be caused by numerous different pathogens. A few of the more common causes are Streptococcus Pneumoniae, Staphylococcus Aureus, Escherichia Coli, Pseudomonas Aeruginosa, and Candida Albicans. Although these are the pathogens involved in the majority of septic shock cases, it is imperative to take the entire clinical picture into account when treating a patient with septic shock. Here we will discuss a seemingly unimpressive dog bite leading to Capnocytophaga canimorsus bacteremia, septic shock and end organ failure.

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 Emergency Room Overcrowding On The Incidence Of Healthcare-Acquired Infections Among Patients, Hayya Ali

Rowan-Virtua Research Day

Emergency department (ED) visits are vital components of healthcare delivery, serving as the primary site for acute medical care, particularly for individuals with urgent medical needs. The ED is among the most crowded hospital units. The fast-paced setting and over-crowdedness of an emergency room have become the reality of every hospital across the United States. Overcrowding causes problems for patients and staff, which include the risk of contracting healthcare-acquired infections. This is due to several factors that in most cases lead to an increase in the number of people within the ED, an increase in mortality and morbidity, and a …

Treatment Rates In A Two-Step Clostridioides Difficile Diagnostic Testing Algorithm, Renee Ringler, Matthew Sims

Posters

Clostridioides difficile is a Gram-positive obligate anaerobe long associated with healthcare-acquired infections in the United States. 1 Clostridioides difficile infection (CDI) has thus become a key metric for assessing facility cleanliness and iatrogenic infection. C. difficile carriage is common, present in approximately 8% of hospitalized patients.2 Therefore, appropriate patient selection for testing and careful testing procedures is crucial to appropriately identify CDI while avoiding the detection of chronic colonization.

Considerable variability exists among institutions regarding standardized CDI laboratory diagnostic methods. Historically, the gold standard for CDI testing was the clinically inefficient toxigenic culture (TC). 3 This was followed by cytotoxic …
