A Comparative Analysis Of Positive And Negative Stimuli For Takotsubo Cardiomyopathy: A Pooled Analysis Of Two Studies And A Systematic Review, Arankesh Mahadevan, Vamsikalayan Borra, Lakshmi Prasanna Vaishnavi Kattamuri, Vikash Jaiswal, Ikechukwu R. Ogbu

School of Medicine Publications and Presentations

Takotsubo cardiomyopathy (TTC) is characterized by transient myocardial dysfunction triggered by both negative and positive emotional experiences, known respectively as broken heart syndrome (BHS) and happy heart syndrome (HHS). Despite the scarcity of comparative analyses between HHS and BHS in the literature, our pooled analysis, incorporating two retrospective registry analyses of 1395 TTC patients (57 HHS and 1338 BHS), reveals that while BHS is more prevalent, both conditions exhibit similar clinical presentations and outcomes. Statistical analyses, utilizing binary random effects models, indicate that diabetes mellitus is less common in HHS patients and serves as a predictor for BHS. Furthermore, there …

Research Symposium

Background: Given the current climate of the pandemic, lung cancer patients are especially vulnerable to complications from severe acute respiratory syndrome coronavirus 2 infection. As a high-risk population group, these patients are strongly advised to receive coronavirus disease 2019 vaccination in accordance with Center for Disease Control and Prevention guidelines to minimize morbidity and mortality. In recent years, immunotherapy has taken a preeminent role in the treatment of non-small cell lung cancer with dramatic improvement in overall survival. Reactive lymphadenopathy following the administration of a coronavirus disease 2019 vaccination can confound the radiographic interpretation of positron emission tomography-computed tomography or …

Too Yellow: An Idiopathic Case Of Autoimmune Hemolytic Anemia, Shreel Patel, Kashif Ali, Donnel Dockery-Joseph, Eunbee Cho, Sriharsha Koneru, Taha Al Hassan, Aramide Tijani, Elimar Gonzalez Morales

Research Symposium

Background: Autoimmune hemolytic anemia is caused by autoantibodies that react with self red blood cells and cause them to be destroyed. Warm AIHA, due to antibodies that are active at body temperature, is the most common type of the AIHA. It is mostly caused by the underlying disease like infections, autoimmune disorders, lymphoproliferative disorders, immunodeficiency or physiologic state like pregnancy. Rarely it happens that there is no underlying cause. Therefore, here we present a case of idiopathic autoimmune hemolytic anemia without any underlying cause.

Case Discussion: A 77 year old lady with known history of the diabetes mellitus type 2, …

Spontaneous Tumor Lysis Syndrome In A Patient With Recent Diagnosis Of Multiple Myeloma — An Unusual Presentation, Taha Al Hassan, Olga G. Cantu-Rodriguez, Eunbee Cho, Edgar G. Dorsey Trevino

Research Symposium

Background: Tumor lysis syndrome (TLS) is an oncologic emergency that surfaces as a constellation of metabolic imbalances due to the rapid destruction of cancer cells and subsequent dissemination of their contents. However, a markedly rare subtype of TLS, known as spontaneous TLS (STLS), occurs without an evident trigger, such as cytotoxic therapy, and carries a similar mortality risk. It is paramount to recognize high-risk cases early and implement therapeutic measures to prevent complications of STLS.

Case Presentation: We present the case of a 74-year-old gentleman with a recent diagnosis of Kappa-restricted multiple myeloma who presented with worsening weakness, tremors, ataxia, …

Little Bit About Liddle: Big Improvement In Blood Pressure, Shreel Patel, Roy Kondapavuluru, Eunbee Cho, Fatimah Bello, Jian Garcia Cruz

Research Symposium

Background: Liddle syndrome is a rare autosomal dominant disorder associated with abnormalities in function of the collecting tubule sodium channel, also called the epithelial sodium channel (ENaC). ENaC function is increased in the Liddle’s syndrome leading to the manifestations of mineralocorticoid excess symptoms, such as hypertension, hypokalemia, and metabolic alkalosis. The diagnosis is made when these features are seen with low renin and low plasma or urinary aldosterone. Genetic testing is not required for the diagnosis of Liddle syndrome. Liddle's syndrome has an excellent response to amiloride.

Case Presentation: A 56-year-old gentleman, with longstanding uncontrolled hypertension was seen for functional …

Case Of Rosai Dorfman Disease In A Patient With Newly Diagnosed Hodgkin Lymphoma, Liza Salloum, Jennifer Rojas Huen, Ricardo Serna, Alisha Valdez

Research Symposium

Background: Rosai Dorfman Disease (RDD, also known as sinus histiocytosis with massive lymphadenopathy) is a rare non-Langerhans cell histiocytosis, classified into nodal (classic) and extranodal disease. Most patients present with non-tender cervical lymphadenopathy, although other sites including the inguinal and axillary regions have been reported. Extranodal disease (~43% of cases) can involve any organ system. RDD is more common in children, but cases have been reported in patients in their 70s. The prognosis of nodal RDD can correlate with the number of nodal groups involved. Many cases can be managed only with observation, although surgery, chemotherapy, corticosteroids, and immunomodulators have …

An Unusual Presentation Of The Severe Hypothyroidism Presenting As Shortness Of Breath, Shreel H. Patel, Kashif Ali, Eunbee Cho, Fatimah Bello, Andres Suarez Parraga, Alcibiades Fleires

Research Symposium

Background: Hypothyroidism is defined as failure of the thyroid gland to produce sufficient thyroid hormone to meet the metabolic demands of the body. Untreated hypothyroidism can contribute to hypertension, dyslipidemia, infertility, cognitive impairment, and neuromuscular dysfunction. It may occur as a result of primary gland failure or insufficient thyroid gland stimulation by the hypothalamus or pituitary gland. Primary gland failure can result from the congenital abnormalities, autoimmune destruction, iodine deficiency, and infiltrative diseases. Patients can clinically present with weight gain, cold intolerance, depression, muscle fatigue, poor concentration, and menstrual irregularities. The best laboratory test for the thyroid assessment is serum …

A True Bloody Emergency: An Unusual Case Of Thrombotic Thrombocytopenic Purpura, Joshua M. Ninan

Research Symposium

Background: Thrombotic thrombocytopenic purpura (TTP) is a primary thrombotic microangiopathy that is classically characterized by thrombocytopenia and microangiopathic hemolytic anemia (MAHA). Although rare with an annual incidence of 3.7 cases per one million adults, it is considered a true hematological emergency due to its fatality rate of almost 100% if appropriate treatment is not initiated immediately. This makes it vitally important to identify and treat patients with TTP, a task that becomes unusually challenging in the absence of the disorder’s other characteristically diagnostic clinical features such as mucosal bleeding, fever, or presence of schistocytes.

A Rare Encounter: Extracranial Meningioma Mimicking Musculoskeletal Neoplasms, Liza Salloum, Jennifer Rojas Huen, Ricardo Serna, Andrew Kolodziej

Research Symposium

Background: Meningiomas are the most common primary brain tumor in adults. While commonly encountered intracranially, 2% manifest extracranially. Although usually benign, 10% of meningiomas can become malignant. Despite their relatively high incidence, they are often difficult to diagnose due to long asymptomatic periods, often diagnosed after mass effect symptoms occur. This case explores the intricacies of diagnosing and managing an extracranial meningioma that mimicked musculoskeletal neoplasms.

Case Presentation: A 70-year-old female, with a history of hypertension and dyslipidemia, presented with diplopia, blurry vision, and intermittent right orbital pain. A recent CT had identified a slow-growing right temporal mass, yet she …

Managing Diffuse Alveolar Hemorrhage In A Critical Care Setting, Yong-Chan Kim, Jessica Marcela Daza, Juan C. Naranjo, Timothy Heath

Research Symposium

Background: Diffuse alveolar hemorrhage (DAH) is defined as disruption of the alveolar-capillary basement membrane, causing bleeding into the alveolar spaces. It is one of the rarest complications in systemic lupus erythematosus (SLE) and life-threatening conditions. Symptoms include shortness of breath, cough, fluctuating fever, and rarely hemoptysis. Complications include acute respiratory distress syndrome. The test of choice for diagnosis is bronchoalveolar lavage (BAL). The hallmark is that BAL aliquots are progressively more hemorrhagic. CT-chest shows ground glass or consolidative opacities that are usually diffuse and bilateral nonspecific. There is no cornerstone therapy for DAH due to SLE. Considering this a fatal …

New Onset Bilateral Pleural Effusion: An Uncommon Presentation Of Subclinical Hypothyroidism Or A Premature Closure Diagnosis Error?, Molly Chapman, Andrea Soto Abarca, Duc Khiem Ngo, Carlos T. Ramos

Research Symposium

Background: Subclinical hypothyroidism is biochemically defined with normal serum-free T4 in the presence of an elevated serum TSH. Common symptoms of an underactive thyroid can include fatigue, weakness, cold intolerance, weight gain despite poor appetite, hair loss, constipation, and depression. Pleural effusions have also been recognized as a clinical sequelae in the literature, where up to 25% of patients can develop a pleural fluid collection in the setting of hypothyroidism. Although not well understood, a mechanism includes an increased capillary permeability that leads to the retention of fluid in pleural cavities and other tissues.

From Carious To Salivarius: A Case Of Streptococcus Salivarius Infective Endocarditis, Maria E. Torres Perez, Ed Wong Alvarado, Cecilia Salinas Domene, Jennifer Rojas Huen, Sara G. Mojica, C. Garza, Usman Sheriff

Research Symposium

Background: Streptococcus salivarius forms part of the Viridans family which accounts for almost 40% of all endocarditis cases. However, S.salivarius is only attributed to 2% of those cases. In the most common setting, S.salivarius is a commensal bacterium of both the oral mucosa and the gut, but it has proven to have infective potential. S.salivarius accounts as an easily missed and commonly misdiagnosed Viridians strep species, but has been implicated as a rare cause of infective endocarditis.

Case presentation: We present the case of a 43-year-old male who presented with worsening fatigue, chest pain, shortness of breath, and subjective fever. …

Asymptomatic Spontaneous Pneumopericardium In A Young Post-Covid-19 Patient: A Case Report, Jose Gomez Casanovas, Andreina Baird Borja, Eric Sanchez, Alcibiades Fleires, Daniela Hernandez

Research Symposium

Background: Pneumopericardium is a rare clinical condition which is defined as the presence of air or gas in the pericardial cavity. Although uncommon to see, it can present after chest trauma, barotrauma, fistula between the pericardium and surrounding structures, gas producing microorganisms and iatrogenic causes. But spontaneous presentations are even more uncommon. Coronavirus Disease 2019 (COVID 19) infection became a large global epidemic and in addition to respiratory symptoms, involvement of other organs such as pericardium was also reported. We here present a young patient post COVID 19 infection with isolated spontaneous pneumopericardium.

Enterococcus Avium Peritonitis, Jian Garcia Cruz, Johanne Chaglasian, Oliverio Abarca Guzman

Research Symposium

Introduction: Enterococcus spp. are part of normal human GI tract flora which has been known to cause community acquired UTI, bacteremia, and nosocomial infections. Enterococcus faecalis and faecium are the most commonly isolated pathogens within enterococcus family although there have been few to no cases reported of peritonitis secondary to enterococcus avium in the setting of recent paracentesis and end-stage-liver disease. The incidence of peritonitis from rare organisms is increasing because of improved microbiological identification techniques. This case is relevant because it shows us that enterococcus avium even if it is not common show be considered when choosing antibiotics coverage …

Syncope As A Presentation Of Waldenstrom Macroglobulinemia, Jian Garcia Cruz, Julio Perez Rodriguez, Roy Subash Kondapavuluru, Eunbee Cho

Research Symposium

Abstract: Syncope as defined by ACC/AHA is defined as a symptom that presents with an abrupt, transient, complete loss of consciousness, associated with inability to maintain postural tone, with rapid and spontaneous recovery without clinical features of other non-syncope causes of loss of consciousness, such as seizure, antecedent head trauma, or apparent loss of consciousness. Syncope is a common complaint treated in the emergency department and a major reason for hospital admissions. Identification of the etiology of syncope is important for diagnostic and therapeutic purposes. Syncope is a symptom as a presentation with multiple differential diagnosis listed and clearly explained …

Grey Turner's Sign Unveiling A Rare Case Of Neuroendocrine Tumor In The Tail Of The Pancreas: A Reminder To Expand The Differential In Young Patients With Chronic Back Pain, Jennifer Rojas Huen, Gilbert Flores Jr., Ismael Pavel Polo Pérez, Nabeel Sarhill

Research Symposium

Background: Pancreatic cancer is often difficult to diagnose due to its asymptomatic nature, silent progression or symptoms overlapping with more common benign conditions. We present a case of a 30-year-old male with chronic worsening back pain, weight loss, and Grey Turner's sign, ultimately leading to the diagnosis of a neuroendocrine tumor in the tail of the pancreas. The rarity of this diagnosis in a young patient with atypical symptoms emphasizes the importance of considering uncommon diagnoses and expanding differentials, even when presented with seemingly typical symptoms, to enable early detection and intervention.

Case Presentation: 30-year-old male past medical history of …

Wait, Wait, Could It Be Autoimmune Pancreatitis? A Case Of Localized Autoimmune Pancreatitis Mimicking Pancreatic Cancer, Grecia Dominguez Rivera, Hari Movva, Heriberto Cantu, Nabeel Sarhill

Research Symposium

Background: Autoimmune pancreatitis (AIP), an IgG4-related disorder, is a rare condition that typically presents as obstructive jaundice and pancreatic enlargement in older adults mimicking the manifestations of pancreatobiliary malignancies. Although the diagnosis of AIP has improved through growing awareness and proposed diagnostic criteria, differentiating between AIP and pancreatic cancer remains challenging.

Case Presentation: A 69-year-old Hispanic male presented with a 1-month history of nausea, epigastric pain, jaundice, and 20-pound weight loss. His medical history revealed type 2 diabetes.

The Great Mimicker. A Case Of Gastrointestinal Tuberculosis., Grecia Dominguez Rivera, Jose Roberto Flores Gonzalez

Research Symposium

Background: Gastrointestinal (GI) tuberculosis (TB) is rare, accounting for 1-3 % of all TB cases worldwide. Mycobacteria enter the GI tract via hematogenous spread from active pulmonary TB, swallowing infected sputum, or ingesting contaminated food. The ileocecal area is most affected; however, tuberculous enteritis can involve any part of the GI tract. The vague clinical presentation makes the diagnosis challenging and often delayed requiring a high index of suspicion.

Case Presentation: A 28-year-old female who emigrated to the US from Mexico presented to the ED with a 4-month history of abdominal pain, vomiting, diarrhea, anorexia, 40-pound weight loss, intermittent fever, …

Spindle-Cell Mesothelioma Arising From The Right Pleura: A Case Report And Review Of The Literature, Duc Khiem Ngo, Karina Torres, Sobia Hassan Memon, Carlos T. Ramos Jr.

Research Symposium

Background: Spindle cell mesothelioma, or Sarcomatoid mesothelioma, is a rare and insidious type of malignant mesothelioma with a high mortality rate. It arises from mesothelial surfaces of the pleural cavity, peritoneal cavity, tunica vaginalis, or pericardium, and it is usually associated with asbestos exposure. Spindle cell mesothelioma could be challenging to treat because most patients have advanced disease at presentation with an average prognosis of six months. In this case report we present a rare case of spindle-cell mesothelioma arising from the right pleura.

Case presentation: An 82-year-old male with a history of atrial fibrillation and coronary artery disease, status …

Delayed Management Of Pfo After Stroke Presentation In A Healthy Hispanic Female, Diana Othon Martinez, Barbara Malaga-Espinoza, Nestor Gerardo Astorga, Vamsikalayan Borra, Roque Mifuji

Research Symposium

Background: Strokes are a leading cause of long term disability. Around 800,000 people in the USA have a stroke every year. (CDC) 25% of the population have a Patent foramen ovale (PFO). Stroke in the presence of PFO has been described to be found in up to 40% of patients with “embolic stroke of undetermined source”, otherwise known as cryptogenic strokes. Despite the aforementioned prevalence, there is mixed data on PFO management options. Current management guidelines include dual anti-platelet therapy, anticoagulants, and percutaneous transcatheter closure. Some studies suggest that PFO might be an incidental finding in patients with cryptogenic stroke. …

Anaphylaxis After Avocado Ingestion In A Patient Located In The Rio Grande Valley, Eric Sanchez, Andreina Baird Borja, David London, Daniela Hernandez, Jose Gomez Casanovas

Research Symposium

Background: The avocado is an integral part of the Tex-Mex cuisine, especially in the Rio Grande Valley. Cases of severe anaphylactic reaction related to avocado mostly occur with previous history of latex-sensitization, also known as "latex-fruit syndrome," rather than caused by avocado alone. One of the major identified avocado allergens is the protein Prs a 1, a chitinase that helps the plant for protection and has cross-reaction with natural rubber latex allergens. According to the most recent national survey done in 2014, the prevalence of anaphylaxis in the United States ranged from 1.6% to 5.1%. Food reactions accounted as the …

Hiding In Plain Sight: Renal Cell Carcinoma Due To Suspected Von Hippel-Lindau Syndrome, Eric Sanchez, Andreina Baird Borja, Jose Gomez Casanovas, Alcibiades Fleires, Daniela Hernandez
