Dear Editor: Kasabach–Merritt syndrome (KMS) is characterised by the association of haemangioma, thrombocytopenia and consumption coagulopathy. The mechanism of consumption coagulopathy is the adhesion and activation of platelets inside the vascular lesion (due to the interaction with the endothelium) with the consequent activation of the whole coagulation(More)
BACKGROUND Enadenotucirev (formerly ColoAd1) is a tumor-selective chimeric adenovirus with demonstrated preclinical activity. This phase 1 Mechanism of Action study assessed intravenous (IV) delivery of enadenotucirev in patients with resectable colorectal cancer (CRC), non-small-cell lung cancer (NSCLC), urothelial cell cancer (UCC), and renal cell cancer(More)
OBJECTIVE To determine whether the features of adenomas identified in a first endoscopic examination may predict the presence of polyps with advanced pathological features that may have gone unnoticed and whether early colonoscopy may benefit these patients. MATERIAL AND METHODS We examined 133 patients with diagnosis of colonic adenomas who had undergone(More)
