Stress-related mucosal damage (SRMD) is a significant cause of morbidity and mortality in critically ill patients due to the gastrointestinal blood loss. Prophylaxis of SRMD with proton pump inhibitors or histamine-2 blockers has gained widespread use in intensive care units. Both demonstrated to be effective in reducing clinically significant bleedings, while PPIs has shown to exert some anti ...

Inflammatory bowel disease, including ulcerative colitis and Crohn's disease, substantially increases the risk of colorectal cancer. However, mechanisms linking mucosal inflammation to the sequence of dysplasia are incompletely understood. Whereas studies have shown oxidative damage to the colon, this study tests whether genotoxicity is elicited systemically by acute and chronic intestinal infl...

BACKGROUND The gut-brain axis plays a potential role in numerous physiological and pathological conditions. Several substances link stomach with central nervous system. In particular, hypothalamo-pituitary-adrenocortical axis, thyrotropinreleasing factor-containing nerve fibers and capsaicin-sensitive nerves are principal mediators of the harmful and protective central nervous system-mediated e...

INTRODUCTION Oxidative stress has been considered to play a primary role in the pathogenesis of stress-induced gastric damage. The aim of this study was to investigate the effects of melatonin, ascorbic acid and β-carotene on stress-induced gastric mucosal damage. MATERIAL AND METHODS Fifty-six male Wistar albino rats were divided into control, stress, stress + standard diet, stress + saline,...

The risk for invasive fungal infections in patients with acute leukemia is generally low (4%–8%), and the routine use of fungal prophylaxis is not warranted except in specific high-risk groups that should be identified among this population. In a prophylactic study with a new agent, fluconazole or itraconazole oral solution represent good choices for the comparator because they are proven bette...

thought of as an imbalance between aggressive factors (acid, pepsin and Helicobacter pylori infection) and local mucosal defenses; the secretion of bicarbonate, mucus and prostaglandins. Although treatment most often is directed at the reduction of aggressive factors, it can be directed at strengthening mucosal defenses of the stomach and the duodenum with so-called cytoprotective agents. Cetra...

Rotavirus gastroenteritis was complicated by Klebsiella Pneumoniae bacteraemia in two infants with glucocorticoid deficient conditions who were treated with 'stress dose' hydrocortisone during their illness. Delayed healing in the context of glucocorticoid administration combined with damage from rotavirus infection may result in increased risk of mucosal invasion by gastrointestinal bacteria a...
