Case Report: Carbon Monoxide Poisoning: A Sleuth, Joel Collins Ii, Wayne Tamaska, Anna Barton, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

We report a case of a 18 year old male who presented via EMS who was called for an unconscious male in his car diagnosed initially with opioid overdose and later found to have carbon monoxide poisoning. The differential diagnosis of carbon monoxide poisoning is someone broad and non specific, but in general, carbon monoxide poisoning can be initially elusive in diagnosis and requires continued consideration. This remains true especially in this case of an unconscious male with initial responsiveness to naloxone. It is predictable that as with time the preponderance and relative commonality of this condition will decrease with …

When Constipation Becomes Lethal: Septic Shock Induced By Stercoral Colitis In A 77-Year-Old Female, Anna Delancy, Nicholas Tomasello, Joan Wiley, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Stercoral colitis is a form of colitis caused by fecal impaction distending the colon and causing fecaloma formation. Fecalomas lead to pressure necrosis of the colon and eventual perforation. The increased intraluminal pressure from the distention of the colon causes vascular compromise and ischemia. The most common locations of necrosis are in the sigmoid colon and rectum . When progressed to perforation, the mortality rate is as high as 60%. The most common cases of stercoral colitis occur in nursing home patients, mentally impaired patients, or those with chronic constipation. Here we describe an unusual case of stercoral colitis causing …

Pathophysiology, Presentation, And Management Of Interstitial Cystitis In The Acute Setting, David Koziel

Rowan-Virtua Research Day

Interstitial cystitis (IC) also known as bladder pain syndrome (BPS) and more infrequently by other monikers represents a debilitating disease with a poorly understood pathophysiology. According to the Centers for Disease Control the incidence of IC ranges from 1 to 5.1 cases per 100,000 individuals. While a relatively rare condition, it is common enough that the provider in the acute setting recognizes the pathophysiology and is familiar with the management of this condition. It is a disease that is more prevalent in women, however men can also be affected. Due to the significant overlap with more common conditions, it is …

Brief Review: Iv Fluid Choice In The Emergency Department, Kaywan Saed, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Normal saline and balanced crystalloids, such as lactated Ringer's (LR) and Plasma-Lyte A, are commonly used in the emergency setting for fluid resuscitation. However, there has been growing interest in recent years in whether balanced crystalloids may be superior to normal saline, particularly in critically ill patients.

Normal saline has been the traditional fluid of choice for decades due to its widespread availability, low cost, and presumed safety. However, normal saline has a high chloride concentration (154 mmol/L), which can lead to hyperchloremic metabolic acidosis and other adverse effects, such as renal vasoconstriction and reduced renal blood flow.

In contrast, …

Case Report: Vocal Cord Paralysis In The Ed, Richard Baluyot, Russell Mordecai, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

The incident rate of vocal cord paralysis varies greatly depending on the cause of paralysis as well as if it's unilateral or bilateral, for this poster we will be focusing on unilateral paralysis. From 1985 to 1995 cancer was the primary cause for vocal cord paralysis, however this shifted to primarily iatrogenic surgical injury from 1996 to 2005. In another study it was found that idiopathic paralysis and tumors to both be the primary cause (31.11% respectively), with surgery consisting of 28.89%, and trauma, brain problems, systemic disease and other causes being 2.2%.

Spontaneous Iliac Arteriovenous Fistula, High-Output Heart Failure, And Cardiac Arrest, J. Maxwell Piraneo, Russell Mordecai, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

High-output heart failure is a potentially life-threatening condition that can lead to cardiac arrest. The most common causes of this condition are obesity, liver disease, arteriovenous shunts, lung disease, and myeloproliferative disorders, however the exact prevalence remains uncertain [1]. Here we describe an unusual case of cardiac arrest as a consequence of high-output heart failure, secondary to rupture of an iliac artery aneurysm into the common iliac vein, with arteriovenous (AV) fistula formation.

Case Report: Cavitary Pneumonia In A 28 Year Old Male, Dan Zaayenga, Katelyn Courtney

Rowan-Virtua Research Day

Cavitary pneumonia can be caused by several different mechanisms. Such causes include suppurative necrosis (pyogenic lung abscess), caseous necrosis (tuberculosis), ischemic necrosis (pulmonary infarction) cystic dilatation of lung structures (ball value obstruction and Pneumocystis pneumonia) as well as malignant processes. Causes are subject to both environmental factors and host susceptibility. The most common cause of infectious process is tuberculosis with its propensity to cause extensive caseous necrosis. The potential for secondary infection after an individual develops a cavitary pneumonia is also great as it provides a shelter for various pathogens the flourish in an environment otherwise usually well-guarded by host …

Rowan-Virtua Research Day

A 35 year old male presented to the Emergency Department (ED) with a rash of his left lateral lower leg of a 2 months duration. The patient had been using an electric space heater and the affected area was the closest part of his body to the heater. A diagnosis of erythema ab igne was made. Here we discuss erythema ab igne in reference to the medical history of the diagnosis, pathophysiology, modern causative heat sources such as laptop computers and treatment.

Sigmoid Perforation Extending Into The Abdominal Wall, Zamran Masih, Wayne Tamaska, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Sigmoid colon perforation and spread into the abdominal wall is a rare condition that can occur due to various causes such as diverticulitis, trauma, malignancy, or iatrogenic injury during surgery. Although rare, sigmoid colon perforation into the abdominal wall can result in significant morbidity and mortality if not promptly diagnosed and treated. Most common cause of diverticular disease leading to perforation is diverticulitis, accounting for 60% of all colonic perforations.

New Onset Lichen Planus And Back Pain Leading To Discovery Of A Peri Aortic Abscess, Monica Diep, Wayne Tamaska, Philip Carhart, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Back pain is a common chief complaint in the emergency department. With the differential ranging from musculoskeletal pain to cauda equina, there are a plethora of diagnoses. Differentiating between benign back pain and back pain that warrants further evaluation and even possible emergent surgical intervention is often a challenge in the acute setting. In this case report, a strange combination of all new symptoms including lichen planus, fevers, chills and atraumatic back pain lead to the eerie and very unexpected diagnosis of a peri-aortic abscess.

Laboratory Evaluation Of An Enzyme Immunoassay To Detect Coccidioides Galactomannan Antigens In Serum Samples, Anneliese Ahrens

Biological Sciences Undergraduate Honors Theses

Introduction: Coccidioidomycosis (cocci) is an infection caused by fungal pathogens in soil of dry and arid regions in the Southwestern states of the United States. The disease can present itself anywhere in the body, but usually is found in the lungs. The symptoms are very similar to the symptoms of a bacterial or viral respiratory infection, which is one of the reasons it is commonly misdiagnosed or left untreated. The CDC reports cases to have increased 143% from 2014 to 2019, with a mortality rate of 200 deaths per year, however this is likely underreported because of the inadequacies of …

Irritable Bowel Syndrome: Proposed Mechanisms Of Pathophysiology And The Underlying Dysregulation Of Brain-Gut Interaction, Hailey Haddix

Senior Honors Theses

Irritable bowel syndrome (IBS) is a disease of the gastrointestinal tract affecting approximately 11-21% of people worldwide (Xiao et al., 2021). This research focuses on the dysregulation of gut homeostasis in IBS and explains how the pathophysiology of the gut is controlled by the bidirectional brain-gut axis. The mechanisms of the brain-gut axis consist of neuro-immune cross talk, neuro-hormone cross talk, microbiome-gut signaling, and the HPA-axis. Each of these contribute to one or more of the possible phenotypes of gut pathophysiology, which could include intestinal permeability, visceral hypersensitivity, and motility disturbance (Xiao et al., 2021). Stress is also an important …

Chronic Overlapping Pain Conditions And Long-Term Opioid Treatment, Maria Ukhanova, Robert W Voss, Miguel Marino, Nathalie Huguet, Steffani R Bailey, Daniel M Hartung, Jean O'Malley, Irina Chamine, John Muench

Faculty, Staff and Student Publications

OBJECTIVES: One in 5 people in the United States lives with chronic pain. Many patients with chronic pain experience a subset of specific co-occurring pain conditions that may share a common pain mechanism and that have been designated as chronic overlapping pain conditions (COPCs). Little is known about chronic opioid prescribing patterns among patients with COPCs in primary care settings, especially among socioeconomically vulnerable patients. This study aims to evaluate opioid prescribing among patients with COPCs in US community health centers and to identify individual COPCs and their combinations that are associated with long-term opioid treatment (LOT).

Introduction and Case Presentation: We report an unusual case of an adult midgut volvulus presenting first as a transverse colon volvulus. A 62-year-old man with no significant past medical history presented to the emergency department with complaints of intractable nausea, vomiting, and abdominal pain for twenty-four hours. He had been evaluated at an outside hospital where an abdominal and pelvis computed tomography was read as a transverse colon volvulus, a vanishingly rare medical condition. A CT reimaging of the abdomen and pelvis illustrated a whirlpool sign in the region of the small bowel, consistent with a small bowel volvulus. In …

Case Series: Continued Remission Of Ptsd Symptoms After Discontinuation Of Prazosin, Christie Richardson, Jonathan Yuh, Jing Su, Martin Forsberg

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Post-traumatic stress disorder is a debilitating chronic illness that affects 6 out of 100 adults after a severe trauma. The alpha-adrenergic antagonist prazosin, which is prescribed off-label for flashbacks and nightmares due to trauma, is often continued indefinitely due to reports of symptoms returning upon discontinuation. There is no standard guidance for a trial of discontinuation of prazosin due to intolerance or side effects. In this case series, three patients are started on prazosin leading to remission of trauma-related symptoms, and symptoms continue to remit after treatment for an average of about 2 years followed by discontinuation of the medication. …

“Healing Can Be A Very Jagged Line”: Reflections On Life As A Covid-19 Long Hauler, Leah M. Hecht, Rhonda Adams, Danielle Dutkiewicz, Debbie Radloff, Mallory N. Wales, Jeffory Whitmer, Dana Murphy, Sara Santarossa

Journal of Patient-Centered Research and Reviews

“Long COVID” — a term referring to COVID-19-associated symptoms and conditions (ie, sequelae) that remain or emerge after resolution of a SARS-CoV-2 infection — is a multifaceted condition about which little is known. As part of formalized patient-engaged research at a large Midwestern health system, patient stakeholders with long COVID (N = 5) wrote stories based on their lived experience, as this was their preferred format for detailing their experience with the condition. These patient stakeholders reviewed one another’s stories, identified relevant quotes, and provided opportunities for elaboration. Independently, a trained researcher extracted quotes from the stories, identified themes, and …

Met Alterations Are Associated With Osimertinib Resistance In Egfr Mutant Lung Cancers, A Meta-Analysis, Annie Le, Marissa Viola, Jun Wang

Research Day

Osimertinib is a third-generation tyrosine kinase inhibitor (TKI) that has been used to treat EGFR mutant lung cancers, especially those with EGFR T790M mutation. Resistance to osimertinib is likely associated with acquired genetic alterations in these cancer cells. Mesenchymal epithelial transition (MET) is a tyrosine kinase and its amplification is frequently seen in osimertinib resistant patients. To investigate whether the presence of MET alteration is associated with osimertinib resistance, a meta-analysis was conducted using published observations of EGFR mutant lung cancer patients treated with osimertinib. Frequencies of MET alterations are variable, ranging from 0-43% in osimertinib resistant patients. MET alteration …

Kearns-Sayre Syndrome: Two Case Reports And A Review For The Primary Care Physician., Chad Richmond, Leonard Powell, Zachary D. Brittingham, Alison Mancuso

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Kearns-Sayre syndrome (KSS) is a mitochondrial encephalopathic disorder. Because mitochondria are ubiquitous organelles that are present in almost every human tissue, their dysfunction can affect nearly any organ system and give rise to a wide range of clinical characteristics. 1: As is the case with most diseases associated with mitochondrial DNA (mtDNA) mutations, the clinical features of KSS were defined before modern molecular genetic classifications emerged. 2: The exact prevalence of KSS is unknown; however, estimates place it at about 1:100,000 people. Although it is a rather rare syndrome, the ability to recognize or consider KSS as part of a …
