A Common Complaint With An Unexpected Diagnosis: A Case Of Mycobacterium Avium Complex Pulmonary Abscesses, Maryam Fallahi, Mark Cheneler, Qazi Haider, Madhukanth Reddy

North Texas Research Forum 2024

Introduction: Mycobacterial infections are an atypical organism for pulmonary infections. These infections are classically separated in tuberculous (MTB) and nontuberculous (NTM) groups due to their differing pathogenicity and microbiologic therapy regimens. MTB is typically treated with a 4-drug therapy known as RIPE (rifampin, isoniazid, pyrazinamide, and ethambutol) however NTM is typically treated with 3- or 4-drug therapy with a backbone of rifampin, macrolide, and ethambutol. Due to the long courses of therapy required for NTM, stringent diagnostic criteria of clinical, radiologic, and microbiologic findings are required. Despite meeting all 3 criteria for diagnosis, not every patient is a candidate for …

It was noted that she has not been seen or heard from by her family members in the last five days. She has no known past medical history and she was unresponsive and hemodynamically unstable in the …

A Challenging Diagnosis Of Intestinal Tuberculosis Mimicking Crohn's Disease, Justin Sanchez, Gabriel Gonzales, Monte Troutman

North Texas Research Forum 2024

Intestinal tuberculosis (ITB) is an underrecognized disease that shares many clinical, radiologic, endoscopic, and pathologic features with Crohn's disease, making differentiation difficult. This poses a significant problem as initiation of immunosuppressives for an assumed diagnosis of CD in a patient with ITB can lead to exacerbation of infection and life-threatening consequences. A 30-year-old Nepali man with a medical history only significant for Raynaud disease presented with a febrile illness, right lower quadrant abdominal pain, and productive cough over the course of a month. He immigrated from Nepal 3 years prior to presentation, denying other risk factors or specific symptoms of …

North Texas Research Forum 2024

Streptococcus gallolyticus, part of the Streptococcus bovis/Streptococcus equinus complex (SBSEC) formerly known as Group D streptococi, is strongly associated with colorectal cancer and infective endocarditis. Its appearance in septic arthritis is rare, and its role in septic arthritis has not been as thoroughly investigated. We present the case of a 69 year old male with a history of atrial fibrillation and hypertension who was admitted to our hospital after undergoing a right knee replacement in 2023 with a chief complaint of right knee pain, fever, and chills. Arthrocentesis and blood cultures were performed, and the patient was started on …

Improving Clostridium Difficile Detection At Medical City Arlington: A Quality Improvement Project, Bremmy Alsbrooks, Nur-Alhuda Shahub, Shabaz Mallick, Jesse Brown

North Texas Research Forum 2024

INTRODUCTION: Hospital acquired Clostridium difficile infection are one of the costliest hospital acquired infections. Over the past year, there were 19 C diff cases. Reasons for this uptick in cases from previous years could be waiting too long for collection (where a patient has C diff on admission, but does not receive testing until several days later), antibiotics, environmental (for example, using the same toilet brush to clean bathrooms on the floor as well as the bathroom in a C diff patient's room, cleaning high touch areas less than two times during the day, etc.), or staff education. From our …

Mast Cell Colitis Associated With Yersinia Enterocolitica, Olufemi Osikoya, Gregory Brennan

North Texas Research Forum 2024

Introduction: Mast cells (MCs) have many functions including regulation of GI epithelial homeostasis, cross talk of the brain gut axis, host immune defenses, and inflammatory pathways. MCs are found in all layers of the GI tract and have been implicated in various gastrointestinal diseases. Although previously described in the literature, mast cell colitis is not considered a distinct clinical entity. This poses a challenge to the gastroenterologist who encounters such pathologic findings. Case Presentation: This is a case of a 76-year-old woman who was referred to the gastroenterology clinic for evaluation of a new diagnosis of colitis. The patient …

Disseminated Coccidioidomycosis Discovered Through Skin Biopsy In A Pregnant Patient From Mexico, Henry Lim, Christina Guo, Marshall Hall, Christian Scheufele, Christopher M. Wong

North Texas Research Forum 2024

Introduction: Coccidioidomycosis is an infection caused by the organism Coccidioides immitis, a fungus endemic to the southwestern United States, Mexico, Central and South America. The presentation of coccidioidomycosis can range from symptoms resembling a simple upper respiratory infection, such as cough, to more severe systemic symptoms including fever, malaise, and chills. Cutaneous lesions of coccidioidomycosis demonstrate a large heterogeneity of clinical manifestations but are significant as they may be the presenting sign of disseminated disease. While usually confined to the lungs, extrapulmonary coccidioidomycosis can occur in about 1 in 200 patients, most commonly associated with immunocompromised status. Pregnancy is an …

A Unique Case Of Spontaneous Pectoral Abscess, Martin Sentmanat, Zachary Shields, David Ross

North Texas Research Forum 2024

Pyomyositis is a rare disease that is often misdiagnosed. Formerly more common in tropic areas, it has been more prevalent in temperate climates in the past couple of decades. Most cases of pyomyositis have a known cause or the patient is immunocompromised, but there are a few documented cases of spontaneous pyomyositis in an otherwise healthy patient. Our case describes a 35-year-old male with no past medical history or history of IV drug use who presented to the emergency department with right sided chest pain. The patient was initially seen and diagnosed with a pectoral muscle strain and fever. He …

North Texas Research Forum 2024

Introduction: Tinea corporis, a superficial fungal skin infection, typically manifests as pruritic annular erythematous scaly plaques with central clearing. This condition can involve every body region. Here we present tinea corporis across various skin pigmentations. The goal of this presentation is to highlight distinctions and similarities in light, medium, and dark skin tones, using the Fitzpatrick scale for stratification of skin types. We hope this can aid primary care clinicians in early recognition of this common condition. Case Presentation: We present a series of cases illustrating the diverse manifestations of tinea corporis across different Fitzpatrick skin types. In Figure 2, …

The Impact Of Tamsulosin And Duration In Catheter-Associated Uti (Cauti) At Weatherford, Feeza Hasan, Diana Steedley, Maria Guerrero, Muhammad Siddique

North Texas Research Forum 2024

Among Catheter-Associated Urinary Tract Infections (CAUTI) acquired in the hospital, approximately 75% are associated with a urinary catheter, which is a tube inserted into the bladder through the urethra to drain urine. Between 15-25% of hospitalized patients receive urinary catheters during their hospital stay. A urinary tract infection (UTI) is an infection involving any part of the urinary system, including urethra, bladder, ureters, and kidney. UTIs are the most common type of healthcare-associated infection reported to the National Healthcare Safety Network (NHSN). The most important risk factor for developing a CAUTI is prolonged use of the urinary catheter. Therefore, catheters …

An Interesting Case Of Suppurative Thrombophlebitis And Perivascular Abscesses As A Cause Of Complicated Mrsa Bacteremia, Ramya Ramachandran, Punjan Patel, Nasima Mehraban, Win Leth Shwe Yee

North Texas Research Forum 2023

Methicillin resistant staph aureus (MRSA) Bacteremia has become a serious re-emerging infection. As per the Centers of Disease Control (CDC), the worsening opioid epidemic has created a snowballing effect, in that there is not only an increase in invasive MRSA infections but also in complications from MRSA. Early source control through the form of early foci identification, obtaining serial blood cultures, decolonization and hygiene measures, appropriate antibiotic stewardship are used to eradicate this bacteria and prevent its spread. There are multiple challenges in treating injection drug users with MRSA bacteremia is not only in medical management but also in trying …

Decreasing Rate Of Clabsi At Medical City North Hills With Implementation Of A “Central Line Cart”, William Mangin, Hong Lou, David Maldonado

North Texas Research Forum 2023

Central line associated blood stream infections (CLABSI) impart both a significant increase in mortality but also a substantial financial burden onto hospitals. Several processes have been shown to reduce the rate of CLABSIs, most of which have already been implemented at Medical City North Hills (MCNH) Hospital. Key areas of improvement are in those of compliance; namely, the implementation of a dedicated central line cart and a reminder check list to help staff. The project involved implementation of a dedicated line cart at MCNH Hospital. The cart contains supplies for placement of central lines, including trialysis catheters, and arterial lines. …

Extraintestinal Salmonellosis Unmasked In A Parotid Mass, Kahmalia-Kalee Sada

North Texas Research Forum 2023

Salmonella infection can cause a wide range of presentations, predominantly gastrointestinal but occasionally with cardiovascular or other extraintestinal manifestations. The diagnosis of extraintestinal salmonellosis requires a high degree of clinical suspicion and should be considered in patients with deep-seated abscesses. [1]. Typically, these types of infections, are extremely rare, and when revealed are typically seen in the immunocompromised patient with chronic illness, HIV, or Hepatitis. While the incidence of nontyphoid salmonellosis is estimated at over 2 million cases annually, extraintestinal manifestations account for less than 1% of cases. Studies have revealed that individuals with diabetes have risk for salmonellosis due …

North Texas Research Forum 2023

Here we present a unique case of a 38-year-old Hispanic male with a history of alcohol abuse and multiple sexual partners, who presented with fulminant sepsis with shock, multiorgan failure, and livedo racemosa after a dog bite a week prior. Patient was intubated on arrival and started on vasopressors and antibiotics. He later developed gangrene of all of extremities, due to the severity of hypoperfusion and disseminated intravascular coagulation (DIC). Eventually, the patient’s clinical status improved, and he was transferred out of the intensive care unit (ICU). Peripheral blood smear showed gram-negative intracellular rods. Blood cultures tested positive for gram-negative …

Early Diagnosis Of Purulent Pericarditis Secondary To Methicillin-Sensitive Staphylococcus Aureus In An End-Stage Renal Disease Patient, Stephen Shey, Alejandro Espinosa-Tello, Amnah Andrabi

North Texas Research Forum 2023

Introduction Purulent pericarditis is a rare illness in the modern age of medicine due to the increased usage of antibiotics. Unfortunately, diagnosis of this disease is often delayed due to its nonspecific symptoms. Without treatment, the mortality is nearly one hundred percent due to major complications such as cardiac tamponade and constrictive pericarditis. As a result, most cases of purulent pericarditis are discovered post-mortem. This case report details an early diagnosis of purulent pericarditis secondary to methicillin-sensitive Staphylococcus aureus (MSSA) in an end-stage renal disease (ESRD) patient. Case Presentation A 66-year-old female with past medical history of ESRD initially presented …

Subacute Stroke Like Presentation Likely Due To Disseminated Histoplasmosis In An Immunocompromised Patient, Ashley R. Diaz, Priya Mohan, Utmitha Konda, Alfonso Manotas, Issac Ichoa

East Florida Research Day 2023

Histoplasmosis capsulatum is an opportunistic fungal infection that is largely asymptomatic and found to have nonspecific signs and symptoms. It predominates in Central and North America, and is one of the leading causes of hospitalization among the fungal family. However, in the right host, such as in this case, a patient with significant immunosuppression can develop serious manifestations as it disseminates outside of the pulmonary system. The challenging element of disseminated histoplasmosis is that despite proper treatment immunocompromised patients will frequently relapse with worsening presentation. There is limited literature on subacute stroke-like presentation in a patient with chronic infection of …
