Advances in Clinical Medical Research and Healthcare Delivery

Herpes zoster is a common disease that can have several complications. Here, we present a case of herpes zoster ophthalmicus with coexisting encephalitis that unfortunately resulted in patient mortality. A 70-year-old male with a past medical history of Parkinson’s disease and schizophrenia presented to the emergency department after being found altered at home. Physical exam was notable for left-sided crusted facial rash, left conjunctival injection, and purulent drainage coming from the right eye. Given the location and appearance of his rash, he was diagnosed with herpes zoster ophthalmicus. There was suspicion for encephalitis given his altered mental status but unfortunately, …

Mycobacterium Shimoidei: A Case Report Of A Rare Nontuberculous Mycobacterial Infection In An American Patient With A Favorable Outcome, Madison Baker, Farah Majdoub, Asad Nasir

Advances in Clinical Medical Research and Healthcare Delivery

Non-tuberculous mycobacteria (NTM) are common environmental pathogens, but they are an uncommon cause of illness. One such mycobacteria, Mycobacterium shimoidei, was discovered in 1968 and found to cause a respiratory illness in 1975. Since then, fewer than 100 cases have been reported worldwide. Symptoms can include cough, fever, weight loss, and hemoptysis This report describes an American patient with no travel history who was found to have significant pulmonary disease caused by this rare non-tuberculous mycobacteria.

A Case Of Listeria Monocytogenes Bacteremia In A Middle-Aged Woman With A History Of Primary Biliary Cholangitis, Caleb Smack, Jared T. Lausen, Aaron Mills

Eastern Virginia Medical Journal

In this report, we discuss the case of a patient with Listeria monocytogenes bacteremia likely resulting from primary biliary cholangitis (PBC) induced cirrhosis. We aim to bolster the body of literature on Listeria bacteremia and establish PBC as a risk factor for this rare complication. Our patient, who presented with sepsis, was subsequently found to have Listeria bacteremia and received intravenous antibiotic treatment of ampicillin for 3 total weeks with complete resolution of her disease. This is the first case suggesting that cirrhosis as a result of PBC may be an independent risk factor for Listeria bacteremia. In patients at …

A Rare Case Of Disseminated Strongyloidiasis Causing Polymicrobial Sepsis In A Patient With Lupus: A Diagnostic Conundrum, Greeshma Molugu, Anupama Chennupati, Ayo Dereje, Machaiah Madhrira

North Texas GME Research Forum 2026

Introduction: Disseminated strongyloidiasis is a very rare condition with case-fatality rates approaching 90%. However, the diagnosis is often delayed because of nonspecific presenting symptoms. Early diagnosis relies on a high index of clinical suspicion, especially in immunocompromised hosts. Long-term corticosteroid therapy, leading to some suppression of inflammatory and immunologic responses, is a well-known risk factor for severe strongyloidiasis.

Case presentation: A 52-year-old male with a past medical history of lupus on chronic corticosteroid therapy presented with chief complaints of dyspnea and diarrhea. He has a recent history of travel to Mexico. Hemoglobin was 5.3. CTAP with contrast showed diffuse colitis …

Altered Natural Killer Cell Function In Children With Severe Malaria, Grace Turyasingura, Kagan A. Mellencamp, Ruth Namazzi, Robert Opoka, Chandy C. John, Geoffrey T. Hart

Paediatrics and Child Health, East Africa

Memory-like natural killer (NK) cells with enhanced antibody-dependent cellular cytotoxicity (ADCC) have correlated with protection from uncomplicated malaria in prior studies. However, the role of NK cells in severe malaria (SM) has not been characterized. In Ugandan sites with moderate and low malaria transmission, we evaluated NK cell (CD56bright, CD56dim, CD56neg) phenotype and ADCC function by flow cytometry in children < 5 years of age with SM (n = 21) and control community children (CC, n = 19). Children with SM had similar total NK cell counts to CC. Children with SM had a higher proportion of LILRB1+ NK cells than CC. The level of malaria transmission …

Garlant, Seshadri Vasan, Komal Jain, Saka Vinod Kumar, Vishnukanth Govindaraj, Vir Singh Negi, Karen E. Kempsell

Research outputs 2022 to 2026

This study investigated immune cell distributions, cell-specific immune markers, and selected biomarker targets in pulmonary tuberculosis (PTB) and extrapulmonary tuberculosis (EPTB) using multiparametric flow cytometry (MFC). Whole blood was collected from 45 individuals, including healthy controls (HC), EPTB, and PTB patients (n = 15/group). Peripheral blood leukocytes were analysed by MFC to characterize CD4+ and CD8+ T cells, natural killer (NK), invariant NKT (iNKT) and NKT cells, classical (CM), intermediate (IM) and non-classical monocytes (NCM), and activated monocytes (AM). Expression of GBP1, CALCOCO2, IFIT3, SNX10, ARG1, PD-1, and PD-L1 was assessed across these immune subsets. Increased frequencies of NK, NKT, …

Cefazolin: A Rare Etiology Of Induced Coagulopathy, Ahmed Ismail, Anam Habib, Cayleigh Blumrick

Department of Medicine Faculty Publications

Cefazolin, a first-generation cephalosporin, is commonly used to treat methicillin-susceptible Staphylococcus aureus (MSSA) infections. Although generally well tolerated, coagulation abnormalities have rarely been reported during therapy. We describe the case of an 81-year-old man treated with prolonged cefazolin for MSSA endocarditis who developed severe coagulopathy characterized by marked elevation of both the international normalized ratio (INR) and activated partial thromboplastin time (aPTT). The abnormalities occurred after initiation of cefazolin and worsened despite cessation of other anticoagulants. Following discontinuation of cefazolin and administration of vitamin K, coagulation parameters rapidly improved and subsequently normalized. This case highlights a rare but clinically significant …

The Diversity Of Flavivirus Antibody Dependent Enhancement (Ade) Profiles From A Pediatric Cohort In Mexico, Maiesha Samiha Mahmood

Graduate Studies Theses and Dissertations 2026

The Aedes mosquito-borne flaviviruses Zika (ZIKV) and dengue (DENV-1-4) cause an estimated 400 million annual infections globally and pose an increasing threat to public health. Typically, individuals infected with ZIKV or a DENV serotype generate neutralizing serotype-specific antibodies and non-neutralizing, cross-reactive antibodies that bind multiple flaviviruses. Upon secondary heterotypic infection, pre-existing antibodies can either protect or exacerbate disease through antibody dependent enhancement (ADE). ADE occurs when non- or sub-neutralizing concentrations of cross-reactive antibodies facilitate viral uptake into FcγR-bearing myeloid cells, enabling infection of otherwise non-permissive cells and driving severe disease. To date, ADE has not been characterized at a population …
