During chemotherapy in patients with gastrointestinal malignancy, the hepatic lesions may occur as chemotherapy-induced lesions or tumor-associated lesions, with exceptions for infectious conditions and other incidentalomas. Focal hepatic lesions arising from chemotherapy-induced hepatopathies (such as chemotherapy-induced sinusoidal injury and steatosis) and tumor-associated eosinophilic absce...

© 2007 Elsevier. All rights reserved. Upper gastrointestinal bleeding (UGIB) and myocardial ischemia/infarction may occur simultaneously because massive UGIB compromises myocardial perfusion and reflex tachycardia increases myocardial oxygen consumption. Many studies were conducted to evaluate the causes and consequences of UGIB after acute myocardial infarction (AMI) and have found that decrea...

The clinical features of corona virus disease 2019 (COVID-19) are variable, but the majority patients experience mild flu-like symptoms. cases severe include complications such as progressive pneumonia, acute kidney injury, multi-organ failure, and even death. This paper explores association between COVID-19 its effect on multiple organ systems how subsequent treatment this can itself lead to m...

massive upper gastrointestinal bleeding is a known complication of advanced sepsis in trauma patients and carries a grave prognosis. however, to our knowledge, an important cause of massive gastrointestinal bleeding, arterio-visceral fistula, has not been discussed in the literature. the most common cause of this unique clinical entity is penetrating high velocity abdominal injuries, although b...

abstractintroduction: hyperplastic polyps of the esophago-gastric junction are seen during endoscopic evaluation of upper gastrointestinal tract. they are usually asymptomatic and discovered accidentally during endoscopic evaluation for other problems. these protrusions are mucosal regenerative response to surrounding mucosal injury. case: here we present a 9-year-old boy presenting with abdomi...

Inflammation is a non-specific immune response to infection, irritation or other injury, the key features being redness, warmth, swelling and pain. A number of mediators are released which alter the resistance of mucosa to injury induced by noxious substances. Oxidative stress is a unifying mechanism of injury in many types of disease processes, including gastrointestinal diseases. It has been ...

Although the numbers have decreased compared with in the past, cases of patients who ingest caustic substances and visit the emergency room are not rare. However, well-summarized data about caustic injuries are insufficient. Therefore, in this article, I will discuss the etiologic causative agents, injury mechanism, and clinical characteristics, as well as the endoscopic evaluation of the degre...
