Inflammatory bowel disease and thromboembolism

引用

World Journal of Gastroenterology 2014年第38期20卷 13863-13878页

作者： petros Zezos georgios Kouklakis Fred Saibil Gastrointestinal Endoscopy Unit University General Hospital of AlexandroupolisDemocritus University of Thrace Division of Gastroenterology Department of Medicine Sunnybrook Health Sciences CentreUniversity of Toronto

patients with inflammatory bowel disease (IBD) have an increased risk of vascular complications. Thromboembolic complications, both venous and arterial, are serious extraintestinal manifestations complicating the course of IBD and can lead to significant morbidity and mortality. patients with IBD are more prone to thromboembolic complications and IBD per se is a risk factor for thromboembolic disease. Data suggest that thrombosis is a specific feature of IBD that can be involved in both the occurrence of thromboembolic events and the pathogenesis of the disease. The exact etiology for this special association between IBD and thromboembolism is as yet unknown, but it is thought that multiple acquired and inherited factors are interacting and producing the increased tendency for thrombosis in the local intestinal microvasculature, as well as in the systemic circulation. Clinicians’ awareness of the risks, and their ability to promptly diagnose and manage tromboembolic complications are of vital importance. In this review we discuss how thromboembolic disease is related to IBD, specifically focusing on: (1) the epidemiology and clinical features of thromboembolic complications in IBD; (2) the pathophysiology of thrombosis in IBD; and (3) strategies for the prevention and management of thromboembolic complications in IBD patients.

World Journal of Gastroenterology 2009年第27期15卷 3434-3436页

Metastatic disease from cutaneous melanoma can af-fect all organs of the body, and varies in its biological behavior and clinical presentation. We present the case of a 58-year-old man who arrived at our clinic with acute abdominal pain, which, after investigation, was diagnosed as acute cholecystitis. The patient under-went laparotomy and cholecystectomy. Two years ago, he underwent surgical removal of a primary cutaneous melanoma on his right upper back. pathological exami-nation revealed the presence of malignant melanoma with a metastatic lesion of the gallbladder.

Frailty and Liver resection: where do we stand?

引用

Hepatoma Research 2020年第2期6卷 11-19页

作者： georgios S.Sioutas Ioannis A.Ziogas georgios Tsoulfas Department of Medicine School of Health SciencesDemocritus University of ThraceAlexandroupolis 68100Greece First Department of Surgery Papageorgiou University HospitalAristotle University of ThessalonikiThessaloniki 54622Greece

As the world population is continuously aging, the number of older patients requiring liver surgery is also on the rise. Data have shown that age should not be a limiting factor for liver resection, as it cannot accurately predict postoperative outcomes. Instead, frailty can serve as a more reliable measure of the patient's overall health and functional reserves. Several frailty assessment tools have been implemented for preoperative risk stratification before liver surgery, and higher scores have commonly been associated with postoperative morbidity, mortality, and length of hospital stay. However, no consensus has been reached on the most useful screening tool. Future studies should focus on comparing the currently available assessment tools, constructing a liver resection-specific tool, and assessing the role of frailty assessment tools in preoperative patient optimization.

NORMA:The Network Makeup Artist—A Web Tool for Network Annotation Visualization

引用

Genomics, proteomics & Bioinformatics 2022年第3期20卷 578-586页

作者： Mikaela Koutrouli Evangelos Karatzas Katerina papanikolopoulou georgios A.pavlopoulos Institute for Fundamental Biomedical Research BSRC“Alexander Fleming”Vari 16672Greece Department of Informatics and Telecommunications University of AthensAthens 15703Greece

The Network Makeup Artist(NORMA) is a web tool for interactive network annotation visualization and topological analysis, able to handle multiple networks and annotations simultaneously. precalculated annotations(e.g., Gene Ontology, pathway enrichment, community detection,or clustering results) can be uploaded and visualized in a network, either as colored pie-chart nodes or as color-filled areas in a 2D/3D Venn-diagram-like style. In the case where no annotation exists,algorithms for automated community detection are offered. Users can adjust the network views using standard layout algorithms or allow NORMA to slightly modify them for visually better group separation. Once a network view is set, users can interactively select and highlight any group of interest in order to generate publication-ready figures. Briefy, with NORMA, users can encode three types of information simultaneously. These are 1) the network, 2) the communities or annotations of interest, and 3) node categories or expression values. Finally, NORMA offers basic topological analysis and direct topological comparison across any of the selected networks. NORMA service is available at http://***, whereas the code is available at https://***/pavlopoulos Lab/NORMA.

Rectal neuroendocrine tumor with uncommon metastatic spread:A case report and review of literature

引用

World Journal of Gastrointestinal Oncology 2016年第2期8卷 231-234页

作者： Nikolaos Tsoukalas Michail Galanopoulos Maria Tolia Maria Kiakou georgios Nakos Aristoula papakostidi georgios Koumakis department of medical oncology 401 general military hospital11525 AthensGreece second department of medical oncology "agios savvas"anticancer hospital11525 AthensGreece department of gastroenterology general hospital of athens"evaggelismos"10676 AthensGreece department of pathology 401 general military hospital11525 AthensGreece

Neuroendocrine tumors of the gastrointestinal tract are rare neoplasms. Rectal neuroendocrine tumors consist approximately the 5%-14% of all neuroendocrine neoplasms in Europe. These tumors are diagnosed in relatively young patients,with a mean age at diagnosis of 56 years. Distant metastases from rectal neuroendocrine tumors are not very common. Herein we describe a case of a rectal neuroendocrine tumor which metastasized to the lung,mediastinum and orbit. This case underscores the importance of early identification and optimal management to improve patient's prognosis. Therefore,the clinical significance of this case is the necessity of physicians' awareness and education regarding neuroendocrine tumors' diagnosis and management.
