Rare Case Of Prosthetic Joint Infection Caused By Salmonella Enterica - A Case Report, Carlos Ramos, Shyama Appareddy, Peter J. Gonzalez

Research Colloquium

Introduction: Collectively, over 1 million total knee arthroplasties (TKA) and total hip arthroplasties (THA) are performed in the United States each year. In 2010 it was estimated that 1.58% of the United States general population has received a TKA. Prosthetic joint infections (PJI) are the most common indication for a TKA revision1 . In total, S. aureus is responsible for about 50% of all prosthetic joint infections, and about 15% are caused by gram negative pathogens2 .

Objective: This is a case report which describes the presentation and clinical course of a 59-yearold female with Salmonella enterica septic arthritis of …

Catheter-Associated Urinary Tract Infections: Patient Characteristics, Treatment, And Clinical Outcomes In One South Texas Acute Care Hospital, Kimberly A. Ambrosini, Jose Campo Maldonado

Research Colloquium

Background: Catheter-associated urinary tract infections (CA-UTIs) account for 40 percent of nosocomial infections worldwide. Their elimination is at the forefront of quality improvement in one South Texas acute care hospital.

Methods: Over a period of 6 months, five CA-UTIs occurred in one South Texas acute care hospital. These cases were identified via regular surveillance by Infection Prevention staff and the Laboratory Department of the hospital. This research reviews patient age, sex, length of stay, bacteria contracted, appropriate antibiotic use, patient characteristics, and overall outcomes.

Results: Between the months of July and December 2021, 5 CAUTIs were contracted. Patients ranged in …

Tuberculosis In Elderly Hispanics: Bcg Vaccination At Birth Is Protective Whereas Diabetes Is Not A Risk Factor, Julia M. Scordo, Genesis P. Aguillón-Durán, Doris Ayala, Ana P. Quirino-Cerrillo, Eminé Rodriguez-Reyna, Francisco Mora-Guzmán, Jose A. Caso, Eder Ledezma-Campos, Larry Schlesinger, Jordi B. Torrelles, Joanne Turner, Blanca I. Restrepo

Research Symposium

Background. Aging increases the risk of tuberculosis (TB) and its adverse outcomes, but most studies are based on secondary analyses, and few are in Hispanics. Diabetes is a risk factor for TB in adults, but its contribution in the elderly is unknown. We aimed to identify the role of diabetes and other risk factors for TB in elderly Hispanics.

Methods. Cross-sectional study among newly-diagnosed TB patients, recent contacts (ReC), or community controls (CoC) totaling 646 participants, including 183 elderly (>60 years; 43 TB, 80 ReC, 60 CoC) and 463 adults (18 to 50 years; 80 TB, 301 …

Covid-19 And Chronic Diabetes: The Perfect Storm For Reactivation Tb?, Genesis P. Aguillón-Durán, Ericka Prieto-Martinez, Doris Ayala, Juan Garcia Jr, John M. Thomas, Juan I. Garcia, Jordi B. Torrelles, Eder Ledezma-Campos, Blanca I. Restrepo

Research Symposium

Background: The Coronavirus disease 2019 (COVID-19) pandemic is predicted to have a net negative effect on tuberculosis (TB) control, with an estimated excess of 6.3 million tuberculosis cases and 1.4 million deaths by 2025. Programmatic issues like the lockdown of TB services affect all patients, while biosocial factors have a differential impact on an individual’s risk for TB or adverse TB outcomes.

Case presentation: We report three cases of incident TB after resolution of COVID-19 episodes.Coincidently, all cases shared a common risk factor: a chronic history poorly-controlled diabetes.

Conclusions: Our findings alert to the threat posed by …

A Case Report Of A Primary Cerebral Abscess Due To Nocardia Asteroides In An Immunocompetent Patient, Ileana Elita Mendez, Nicole Marie Barreto, Alan Lanurias, Luis Alberto Rosas

Research Symposium

Background: Brain abscesses caused by Nocardia are rarely reported and have high mortality. It usually affects patients who are immunocompromised and initiates as a lung infection that disseminates hematogenously, though it can also affect those immunocompetent. Cerebral nocardiosis imitates brain tumors, which can delay the initiation of the appropriate antibiotic therapy.

Case Description: We present a case of a 64-year-old immunocompetent male with multiple cerebral abscesses who presented with headaches, left-sided weakness, and ataxia. Upon imaging, multiple brain lesions were revealed. The patient underwent craniotomy and drainage of the mass. He was initially empirically treated, though cultures later grew Nocardia …
