Temporal Artery Pseudoaneurysm In A Pediatric Patient, Gowri Gowda, Donald Mendoza, Amanda Tullos, Jessica Zagory, Malachi Sheahan Dec 2023

Temporal Artery Pseudoaneurysm In A Pediatric Patient, Gowri Gowda, Donald Mendoza, Amanda Tullos, Jessica Zagory, Malachi Sheahan

School of Medicine Faculty Publications

Superficial temporal artery pseudoaneurysms are an uncommon vascular pathology that can present after head or facial trauma. Furthermore, they are rarely reported in the pediatric population. Ultrasound can be a useful tool in the diagnosis because it is easily accessible and can be rapidly acquired. We report a case that demonstrates the utility of ultrasound in the diagnosis of a superficial temporal artery pseudoaneurysm.

BACKGROUND: The American Academy of Orthopedic Surgery recommends intra-articular corticosteroid injections (CSIs) for managing hip osteoarthritis (OA) based on short-term, prospective studies. Recent retrospective studies have raised concerns that CSIs may lead to rapidly progressive OA (RPOA). We sought to systematically review the literature of CSIs for hip OA to estimate the incidence of RPOA. METHODS: MEDLINE, Embase, and Cochrane Library were searched to identify original research of hip OA patients receiving CSIs. Overall, 27 articles involving 5831 patients published from 1988 to 2022 were included. Study design, patient characteristics, CSI details, follow-up, and cases of RPOA were recorded. Studies …

Cytomegalovirus And Varicella Zoster Virus Coinfection-Associated Central Hypoventilation Syndrome (Ondine's Curse), Marine Isakadze, Benjamin Zwain, Alan J. Velander, Jesus Lovera Nov 2023

Cytomegalovirus And Varicella Zoster Virus Coinfection-Associated Central Hypoventilation Syndrome (Ondine's Curse), Marine Isakadze, Benjamin Zwain, Alan J. Velander, Jesus Lovera

School of Medicine Faculty Publications

Central hypoventilation syndrome (CHS) is a rare condition resulting from damage to the respiratory centers in the central nervous system (CNS). It can be congenital or acquired and can cause hypoventilation, inadequate gas exchange, and respiratory failure, often during sleep but sometimes even while awake. CHS can lead to respiratory failure and life-threatening complications if not identified promptly. In this report, we present a rare case of a patient with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), who developed CHS likely due to an opportunistic infection by cytomegalovirus (CMV) and varicella zoster virus (VZV), manifesting as a lesion in the …

Normal thyroid hormone levels are crucial for the homeostasis of many metabolic cycles and processes throughout the human body. Thyroid dysfunction, such as thyrotoxicosis, can result from many different etiologies, including Graves' disease (GD), toxic multinodular goiter (MNG), and toxic adenoma. These hyperthyroid disease states can cause devastating complications and disease, including the disruption of the bone remodeling cycle and skeletal development, which can result in osteoporosis. Osteoporosis is characterized by a decrease in bone mineral density and a propensity for fragility fractures. In addition to patients with overt hyperthyroidism, studies have provided evidence of other high-risk patient demographics, such …

Background: Bivalent mRNA vaccines were recommended since September 2022. However, coverage with a recent vaccine dose has been limited, and there are few robust estimates of bivalent VE against symptomatic SARS-CoV-2 infection (COVID-19). We estimated VE of a bivalent mRNA vaccine dose against COVID-19 among eligible U.S. healthcare personnel who had previously received monovalent mRNA vaccine doses. Methods: We conducted a case-control study in 22 U.S. states, and enrolled healthcare personnel with COVID-19 (case-participants) or without COVID-19 (control-participants) during September 2022–May 2023. Participants were considered eligible for a bivalent mRNA dose if they had received 2–4 monovalent (ancestral-strain) mRNA vaccine …

Left Juxtaposition Of The Right Atrial Appendage: Pitfalls In Diagnosis, Kanya Singhapakdi, Wesam Sourour, Thomas Kimball

School of Medicine Faculty Publications

Several congenital anomalies of the right atrial appendage (RAA) have been described including aneurysm, herniation (in association with a pericardial defect), and left juxtaposition. The left juxtaposition of the RAA (LJRAA), first described by Birmingham in 1893 and subsequently introduced by Dixon in 1954, is usually associated with complex cardiac malformations such as obstruction of the left ventricular outflow tract. In this case report, we will describe an unusual variant of LJRAA in the absence of any other cardiac defects, which was initially misinterpreted as an aortic dissection. The correct diagnosis was made after careful reinterpretation and the use of …

PURPOSE. Patients deficient in peroxisomal β-oxidation, which is essential for the synthesis of docosahexaenoic acid (DHA, C22:6n-3) and breakdown of very-long-chain polyunsaturated fatty acids (VLC-PUFAs), both important components of photoreceptor outer segments, develop retinopathy present with retinopathy. The representative mouse model lacking the central enzyme of this pathway, multifunctional protein 2 (Mfp2−/−), also show early-onset retinal decay and cell-autonomous retinal pigment epithelium (RPE) degeneration, accompanied by reduced plasma and retinal DHA levels. In this study, we investigated whether DHA supplementation can rescue the retinal degeneration of Mfp2−/− mice. METHODS. Mfp2+/− breeding pairs and their offspring were fed a 0.12% DHA …

School of Medicine Faculty Publications

Remarkable medical advancements have been made for people with cystic fibrosis (CF) in recent years, with an abundance of research continuing to be conducted worldwide. With concern for limitations in access to highly effective CFTR modulators, as well as the recent Coronavirus Disease-19 pandemic, there has been a consistent effort to understand and improve CF screening, disease burden, diagnosis, and management. Our aim in this review is to present articles from 2022 with an emphasis on clinically relevant studies. We hope this will serve as a broad overview of the research published in the past year.

Tumor microbiota can produce active metabolites that affect cancer and immune cell signaling, metabolism, and proliferation. Here, we explore tumor and gut microbiome features that affect chemoradiation response in patients with cervical cancer using a combined approach of deep microbiome sequencing, targeted bacterial culture, and in vitro assays. We identify that an obligate L-lactate-producing lactic acid bacterium found in tumors, Lactobacillus iners, is associated with decreased survival in patients, induces chemotherapy and radiation resistance in cervical cancer cells, and leads to metabolic rewiring, or alterations in multiple metabolic pathways, in tumors. Genomically similar L-lactate-producing lactic acid bacteria commensal to other …
