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.

Hepatopulmonary Syndrome In A 22 Year Old Gentleman With Liver Cirrhosis, Blesset Alexander, Joseph Caporusso, Priyasha Suri

Research Symposium

Background: Hepatopulmonary syndrome is a severe complication of end-stage liver disease characterized by triad of liver disease, intrapulmonary vascular dilatation, and arterial hypoxemia. Although the pathogenesis is not completely understood, pulmonary vascular dilatation occurs due to imbalance between vasodilators and vasoconstrictors. Liver injury is thought to increase endothelin production and cause bacterial translocation, causing increased nitric oxide production, causing vasodilation of pulmonary vasculature. History and physical examination are important in leading the physician to the correct diagnosis as the majority of these patients present with non-specific clinical manifestations and imaging. Identification of specific physical exam findings is important in not …
