Introduction: Although most cases of colon ischemia (CI) are mild and self-limiting, when severe it implies high mortality rates. We aimed to evaluate the risk predictive value classification proposed by American College Gastroenterology (ACG) guidelines (2015), created provide a management algorithm. Methods: A retrospective multicenter study was conducted on adult patients with definite CI (clinical, endoscopic, pathologic culture criteria), between 2013 2016. Data collected clinical...

Cytomegalovirus (CMV) infection in ulcerative colitis (UC) is common during relapses however true CMV rare. It poses as a clinical challenge since no optimal method for relevant has been determined even though current recommendations agree on histology/immunohistochemistry (IHQ). However these parameters require extensive biopsies diagnosis and are not readily available most centres. Therefore based decision seems peremptory. Clinical, laboratory, endoscopic, pathological data of patients...

Die Pi*Z-Mutation im SERPINA1 Gen führt zur Akkumulation von abnormalem Alpha-1-Antitrypsin (AAT) in Hepatozyten. Dies zu Einschlusskörpern und proteotoxischem Stress. heterozygote Variante (Pi*MZ) stellt einen wichtigen Risikofaktor für die Entwicklung einer Leberzirrhose bei Individuen mit vorbestehenden Lebererkrankung dar. Um ihren Stellenwert der Gesamtpopulation klären, haben wir Pi*MZ-Individuen Trägern homozygoten (Pi*ZZ), jeweils ohne vorbestehende Lebererkrankung, verglichen.

A 51-year-old man was referred to our institution for removal of a large semipedunculated polyp (0-Isp) involving the appendiceal orifice ([Fig. 1]).
