A case of an inverted appendiceal stump with dysplastic mucosa mimicking cecal polyp managed by a combined endoscopic laparoscopic approach.

Endoscopic finding of invaginated appendiceal stump mimicking polyp is very rare. We present a case of patient with appendiceal stump mimicking cecal polyp covered with dysplastic mucosa which makes it even more rare. Polypoid lesions involving the appendiceal area represent a specific diagnostic-therapeutic dilemma.

Infliximab rescue therapy in a patient with acute severe ulcerative colitis and coronavirus disease 2019 followed by Escherichia coli 0157:H7 infection: a case report.

The management of patients with acute severe ulcerative colitis and SARS-CoV-2 presents a clinical challenge. We report on the first case of a patient with acute severe ulcerative colitis and mild coronavirus disease 2019 (COVID-19) who received rescue infliximab therapy, followed by a relapse caused by enterohemorrhagic Escherichia coli 0157:H7. The treatment challenges we faced were biologic therapy administration during active COVID-19, about which little was known at the time, and how to treat EHEC due to the risk of hemolytic uremic syndrome.

Inflammatory bowel disease and SARS-CoV-2 pandemic: current knowledge and recommendations.

In the last year, we are facing a pandemic caused by SARS-CoV-2 which causes a disease called COVID-19. In everyday practice, we encounter a number of issues related to IBD patients and COVID-19. So far, we have a lot of information regarding issues of IBD patients and COVID-19, but they are scattered across numerous scientific articles.

Anemia of chronic disease: illness or adaptive mechanism.

The anemia of chronic disease (ACD) is the most prevalent anemia after iron deficiency anemia. It is associated with infectious, inflammatory and neoplastic disease. ACD is a medical condition caused by the release of cytokines which mediate inflammatory and immune response (tumor necrosis factor, interleukins 1 and 6, and interferon).

[Calcified deep vein thrombosis in a patient with recurrent deep vein thrombosis and sarcoidosis].

In this article, we present a rare case of calcified deep vein thrombosis in a 42-year-old female patient with frequent relapses of pulmonary sarcoidosis since 1995, for which she was on maintenance therapy with corticosteroids and with consequential secondary diabetes. Recent femoral vein thrombosis was diagnosed with color Doppler in 2012. At the same time, calcified occlusive thrombus in vena cava inferior from the level of renal vein to the confluence of hepatic veins was diagnosed on abdominal multi-slice computed tomography (MSCT).
