Rare Case Of Mycobacterium Avium Complex Peritonitis In A Patient With Multiple Myeloma Undergoing Peritoneal Dialysis, Sacide S. Ozgur, Nida Ansari, Dhruv Patel, Ryan Rahman, Raymond Shih

Journal of Community Hospital Internal Medicine Perspectives

Mycobacterium avium complex (MAC) infections can present as a variety of severe diseases. While it has a predilection for immunocompromised patients such as those with Human immunodeficiency virus (HIV), it can also affect immunocompetent patients as well. One of the rare yet severe diseases that MAC infections can present is MAC peritonitis. Often hard to distinguish from other causes of peritonitis, high clinical suspicion should be maintained for those who are susceptible. Here we present an 85-year-old female with a past medical history of end-stage renal disease on peritoneal dialysis who presented with nausea and vomiting. She was found to …

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 GME 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 …

North Texas GME Research Forum 2024

Toxic Shock Syndrome (TSS) is a toxin induced illness characterized by fever, rash, and hypotension. TSS low incidence report and rapid onset of clinical symptoms makes getting to the diagnosis critical so that treatment can be started as soon as possible. A 65-year-old woman was brought into the emergency department (ED) after being found on the floor unresponsive during a well fair check. 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 …

Case Report: Streptococcus Gallolyticus Prosthetic Joint Infection, Jeffrey Dickerson, Liza Salloum, Amaan Sheikh, Madhukanth Reddy, Bryan Youree

North Texas GME 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 …

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

North Texas GME 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 …

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

North Texas GME 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 …

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

North Texas GME 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 …

Characterization Of Antibiotic Susceptibility Profiles Of Extensively- And Pan-Drug Resistant Acinetobacter Baumannii Clinical Isolates, Rachel Carr, Justin Halim, Rebecca Fliorent, Henry Fraimow, Dejan Nikolic, Valerie Carabetta

Rowan-Virtua Research Day

Acinetobacter baumannii is an opportunistic pathogen common in intensive care units (ICUs), particularly among immunocompromised individuals. Nosocomial A. baumannii infections have become increasingly problematic in recent years, as these bacteria rapidly acquire antibiotic resistance, leading to the emergence of multidrug, extensively drug and pan drug-resistant (MDR, XDR, and PDR, respectively) isolates. Recently, Cooper University Hospital (CUH) experienced a large increase in highly drug-resistant A. baumannii infections, which had a mortality rate of 60%. Oftentimes, physicians had to turn to combinations of drugs with no experimental verification or historically shelved antibiotics, such as the polymyxins, in a desperate attempt to save …

Identification Of Molecular Markers Associated With Copd In Non-Smokers And Smokers: A Bioinformatics Analysis, Agede O. Ayodele, Isa M. Wasagu, Ademola E. Fawibe, Alakija K. Salami

The University of Louisville Journal of Respiratory Infections

Background

Even though the proportional burden of COPD among never-smokers is significant in both developing and developed nations, accounting for around 30% of all COPD in the community, there is little awareness of the prevalence of COPD in this population. Understanding the molecular processes that underlie COPD in nonsmokers is essential.

Methods

Dataset (GSE146560) was acquired from the Gene Expression Omnibus (GEO). The limma and clusterProfiler software tools were used to identify differentially expressed genes (DEGs) and conduct a functional enrichment analysis respectively.

Results

In all, 10,583 DEGs were found, of which 1,065 were up-regulated and 9,518 were down-regulated. The …

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

North Texas GME 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 …

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 GME 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 …

North Texas GME 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 …

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

North Texas GME 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. …
