Primary Pulmonary Artery Sarcoma Confined to the Left Pulmonary Artery.

Primary pulmonary artery sarcomas (PPAS) are extremely rare tumors that are often mislabeled as pulmonary emboli (PE). PPAS usually involve the pulmonary trunk and are histologically classified as leiomyosarcoma, spindle cells sarcoma, fibrous histiocytoma, or undifferentiated sarcoma. Our case involved a 78-year-old man with an undifferentiated PPAS confined to the left pulmonary artery that was initially misdiagnosed as a PE.

Pulmonary arterial hypertension and acute respiratory distress syndrome in a patient with adult-onset stills disease.

Adult-onset Still's disease (AOSD) is an inflammatory disorder characterized by recurrent fevers, arthralgia, leukocytosis, and a salmon-colored rash. Diagnosis is made based on the Yamaguchi criteria. Various cardiac and pulmonary manifestations have been described in association with AOSD, including acute respiratory distress syndrome (ARDS) and pulmonary arterial hypertension (PAH).

The Use of Tranexamic Acid for Upper Gastrointestinal Bleeding by Medical and Surgical Intensivists: A Single Center Experience.

Background: Tranexamic acid (TXA) may be beneficial in the management of upper gastrointestinal bleeding (UGIB). We sought to investigate how frequently intensivists at our academic institution use TXA for patients with UGIB, and to investigate whether the utilization rate of TXA differs between surgical and medical intensivists, and provide an updated literature review on the subject.

Methods: We performed a retrospective cohort study of patients admitted for UGIB to the surgical intensive care unit (SICU) and the medical intensive care unit (MICU) at our academic healthcare facility (University of Florida Health - Shands Hospital) from January 1, 2013 to December 31, 2016.
