An Unexpected Case Of Herpes Simplex Virus Esophagitis Presenting Amidst Corticosteroid Therapy For An Acute Copd Exacerbation: A Case Report, Aqeel Khanani, Kayvan Mirhadi

Advances in Clinical Medical Research and Healthcare Delivery

Herpes simplex virus (HSV) is prevalent worldwide, with a recent report by the World Health Organization estimating that 3.7 billion individuals under the age of 50 have been infected by the virus. After the initial infection, HSV-1 enters a latent phase with the potential for intermittent reactivation, often secondary to episodes of infection, stress, or immunosuppression. Per current literature review, esophageal involvement in the form of herpes simplex virus esophagitis (HSVE) is more commonly associated with immunocompromised patients, such as transplant recipients and HIV-positive individuals. The patient discussed in this report is a 79-year-old female with a past medical history …

Frequency Of Bystander Exposure To Antibiotics For Enteropathogenic Bacteria Among Young Children In Low-Resource Settings, Elizabeth T. Rogawski Mcquade, Stephanie A. Brennhofer, Sarah E. Elwood, Timothy L. Mcmurry, Joseph A. Lewnard, Estomih R. Mduma, Sanjaya Shrestha, Najeeha Talat Iqbal, Pascal O. Bessong, Gagandeep Kang

Department of Paediatrics and Child Health

Children in low-resource settings carry enteric pathogens asymptomatically and are frequently treated with antibiotics, resulting in opportunities for pathogens to be exposed to antibiotics when not the target of treatment (i.e., bystander exposure). We quantified the frequency of bystander antibiotic exposures for enteric pathogens and estimated associations with resistance among children in eight low-resource settings. We analyzed 15,697 antibiotic courses from 1,715 children aged 0 to 2 y from the MAL-ED birth cohort. We calculated the incidence of bystander exposures and attributed exposures to respiratory and diarrheal illnesses. We associated bystander exposure with phenotypic susceptibility of E. coli isolates in …

Department of Biological & Biomedical Sciences

Coronavirus disease 2019 (COVID-19) has been a pandemic disease reported in almost every country and causes life-threatening, severe respiratory symptoms. Recent studies showed that various environmental selection pressures challenge the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infectivity and, in response, the virus engenders new mutations, leading to the emergence of more virulent strains of WHO concern. Advance prediction of the forthcoming virulent SARS-CoV-2 strains in response to the principal environmental selection pressures like temperature and solar UV radiation is indispensable to overcome COVID-19. To discover the UV-solar radiation-driven genomic adaption of SARS-CoV-2, a curated dataset of 2,500 full-grade genomes from …

How Environmental Change Will Impact Mosquito-Borne Diseases, Arsal Khan

Master's Projects and Capstones

Mosquitos, the most lethal species throughout human history, are the most prevalent source of vector-borne diseases and therefore a major global health burden. Mosquito-borne disease incidence is expected to shift with environmental change. These changes can be predicted using species distribution models. With the wide variety of methods used for models, consensus for improving accuracy and comparability is needed. A comparative analysis of three recent modeling approaches revealed that integrating modeling techniques compensates for trade-offs associated with a singular approach. An area that represents a critical gap in our ability to predict mosquito behavior in response to changing climate factors, …

Neurosyphilis: A Monkey Among Men, Cameron Rowe Do, Nathan Buckley Do, Bhaskar Chhetri Md, Suresh Paudel Md

Journal of Community Hospital Internal Medicine Perspectives

Neurosyphilis is the progression of the untreated sexually transmitted infection caused by Treponema pallidum. When the initial infection is not adequately treated, progression of primary syphilis can lead to a wide variety of serious health sequelae. While neurosyphilis can appear up to 10-30 years after the initial infection, syphilis can invade the nervous system at any stage of infection and can imitate symptoms of many other diseases. This variety of symptoms is why syphilis has been called “The Great Pretender” or “The monkey among diseases” (12). This is a case report of an 83-year-old female with a history of multiple …

Covid-19 Case Complicated With Organizing Pneumonia And Pneumothorax: A Case Report, Tammy E. Phillips, Hammad A. Bhatti, Minh Q. Ho

The University of Louisville Journal of Respiratory Infections

Organizing pneumonia can be idiopathic or caused by multiple etiologies, including viral or bacterial pneumonia, drugs, and autoimmune disorders. It can rarely lead to cyst formation and pneumothorax with the exact mechanism remaining unclear. This case presents a previously healthy 50-year-old male who contracted COVID-19 with subsequent development of organizing pneumonia and pneumothorax. Patients presenting with hypoxic respiratory failure due to COVID-19 should be screened for organizing pneumonia upon discharge. This case also illustrates the importance of following such patients radiologically to monitor interstitial lung disease and consider pneumothorax for patients re-presenting with acute symptoms.
