Examining The Matrix: A Case Of Anti-Nuclear Matrix Protein 2 (Nxp-2) Positive Dermatomyositis, Victoria Cuello, Ramiro Oquita, Emilia Dulgheru
Research Symposium
Background: Dermatomyositis is a disease characterized by proximal muscle weakness, elevated muscle enzymes and cutaneous skin findings including heliotrope rash, periungual erythema, Gottron’s papules/sign and shawl-sign. Myositis-specific autoantibodies (MSA) can be used to predict disease manifestations, response to therapy and prognosis. Specifically, patients with dermatomyositis with positive anti-nuclear matrix protein (NXP-2) typically present with classical skin findings, subcutaneous edema, profound muscle weakness, severe dysphagia and hypophonia.
Case Presentation: A 21-year-old Hispanic lady presented to the hospital for severe muscle weakness. She reported soreness in her thighs for three months prior to presentation followed by arm soreness. She also developed a …
A True Bloody Emergency: An Unusual Case Of Thrombotic Thrombocytopenic Purpura, Joshua M. Ninan
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.
Case Presentation: A 30-year-old gentleman with …

Research Symposium
Introduction: Mixed cryoglobulinemia syndrome (MCS) is a systemic inflammatory syndrome affecting small-medium sized vessels due to the presence of type II or III cryoglobulins in the serum. MSC can manifest as systemic vasculitis with symptoms varying from weakness, arthralgia, palpable purpura, peripheral neuropathy, and renal involvement. The most common cause of MCS includes lymphoproliferative disorders, autoimmune diseases and viral infections, with hepatitis C virus (HCV) being the most common etiology.
Case Presentation: A 60-year-old lady was referred to our office for evaluation of rheumatoid arthritis. She reported history of bilateral thumb pain, bilateral knee pain associated with episodes of swelling, …
Clinical Characteristics And Risk Factors For Mortality During The 'First Wave' Of Covid-19 In Reynosa, Tamaulipas, Luis G. Vargas Garcia, Francisco E. Díaz Cisneros, Antonio Gutiérrez Sierra, Juan Rosales Martínez, Manlio F. Lara Duck, Netzahualcoyotl Mayek Pérez
Clinical Characteristics And Risk Factors For Mortality During The 'First Wave' Of Covid-19 In Reynosa, Tamaulipas, Luis G. Vargas Garcia, Francisco E. Díaz Cisneros, Antonio Gutiérrez Sierra, Juan Rosales Martínez, Manlio F. Lara Duck, Netzahualcoyotl Mayek Pérez
Research Symposium
Background: The COVID-19 pandemic has impacted public health in Mexico. As of February 2020, there have been at least four "waves" of contagion that resulted in 5.82 million positive cases and more than 325 thousand deaths. At the beginning of the COVID-19 pandemic, hospital and population-based information was available, frequently with non-specific symptoms. Little was known about the risk factors for mortality in specific conditions. We described the clinical characteristics of patients with COVID-19 in Reynosa, Tamaulipas during 2020 and identified the risk factors for mortality.
Methods: The COVID-19 cases registered from March to November 2020 in Reynosa were divided …

That Which Keeps On Giving - A Case Of Class Iv Diffuse Proliferative Lupus Nephritis In A Hispanic Woman With Underlying Systemic Lupus Erythematosus, Josenny L. Rodriguez-Paez, Christine E. Loftis, Rosa White-Guedez
Research Symposium
Background: Glomerulonephritis is the primary cause of morbidity and mortality of systemic lupus erythematosus (SLE). Lupus nephritis is characterized by immune complex deposition in the mesangium leading to complement activation and hypocomplementemia. Studies show that up to 60% of adults with lupus develop renal involvement and it has been well established that Hispanic patients show poorer outcomes than Caucasians despite advances in treatment. Preserved kidney function with new-onset proteinuria should raise clinical suspicion for acute lupus nephritis. Further evaluation with a kidney biopsy is paramount in establishing a diagnosis, helping to define treatment strategy, and determining response to treatment.
