RESUMO
A case series is presented of five overweight or obese patients with confirmed coronavirus disease 2019 (COVID-19) in South Miami, Florida, United States. A multitude of coagulation parameters was suggestive of a hypercoagulable state among the hospitalized COVID-19 patients. This article reports various manifestations of hypercoagulable states in overweight and obese patients, such as overt bleeding consistent with disseminated intravascular coagulation, venous thromboembolism, gastrointestinal bleeding as well as retroperitoneal hematoma. All of the required admission to the intensive care unit and subsequently patients died. The characteristics of COVID-19-associated coagulopathy are atypical and warrant a further understanding of the pathophysiology to improve clinical outcomes, specifically in overweight or obese patients.
RESUMO
In 2008, the American Cancer Society endorsed computed tomography colonography (CTC) to virtually visualize the large intestine and help diagnose atypical pathological features of the colon. Virtual navigation through the colon provides the physician an increased opportunity to locate abnormalities without the risks associated with traditional colonoscopy. This article discusses why patients undergo CTC, how the examination is performed, and how patients should prepare. Although CTC primarily is used for the detection of polyps and cancerous tumors, the examination can benefit any patient who requires a minimally invasive alternative to a traditional colonoscopy.
