BACKGROUND: Despite sparse pediatric data on effectiveness, the majority of critically ill children receive medications to prevent gastrointestinal (GI) bleeding. Stress ulcer prophylaxis may have unintended consequences-increasing the risk of nosocomial infections-which may be more serious and common than the bleeding which these drugs are prescribed to prevent. Randomized controlled trials (RCTs) in pediatric critical care are exceptionally challenging to complete, thus a rigorous pilot RCT is crucial...

Ulcerative Colitis (UC) is a lingering type of Inflammatory Bowel Disease (IBD) which affects the colon mucosa. Ulcerative colitis is majorly associated with oxidative stress and inflammation in colon tissue leading to damage. Averrhoa bilimbi L. fruit is rich in antioxidant phytochemicals including Vitamin C. In the current research, we have evaluated the defence mechanism of Averrhoa bilimbi L. on Ulcerative Colitis (UC). Male wistar rats were treated with Averrhoa bilimbi L. fruit extract (50mg/kg/bwt and 100mg/kg/bwt) and a standard drug Sulfasalazine (100mg/kg/bwt) for 6 consecutive days via intra peritoneally...

INTRODUCTION: Despite its vast occurrence, the aetiology of Recurrent Aphthous Stomatitis (RAS) still remains unknown and its aetiology is multifactorial. The factors believed to be associated with the aetiology of RAS, may disturb the equilibrium of oxidant-antioxidant status of the organism and may accelerate the formation of free radicals, resulting in Oxidative Stress (OS). Psychological stress is believed to act as a triggering factor or modifying factor for RAS. AIM: To find whether oxidant-antioxidant status and psychosocial stress play a role in the pathogenesis of RAS...

Background/Aims: Although proton pump inhibitors (PPIs) have been widely used for the prevention and treatment of stress gastric ulcers in hospital settings, there are concerns that PPIs increase the risk of Clostridium difficile infection (CDI). However, little is known about the risk of CDI following PPI and histamine-2 receptor antagonist (H2RA) use. We evaluated the comparative hospital-acquired CDI occurrence risk associated with the concurrent use of PPIs versus H2RAs. Methods: A systematic search of PubMed, MEDLINE/ Ovid, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, and Google Scholar through August 19, 2016, identified 12 studies that reported the hospital-acquired CDI occurrence following H2RA and PPI use for the prevention and treatment of stress gastric ulcers...

The aim of this study was to prepare and optimize a novel type of in situ gel-forming solid dosage form (gfSDF) to be used in the treatment of mucosal/skin ulcerations. For this purpose, a simple but reliable syringe-based hot melt/moulding method was employed. Chloramphenicol (antibiotic) and ibuprofen (anti-inflammatory) were chosen as model active pharmaceutical ingredients (APIs) to be loaded into the gfSDFs. To optimize the formulations, the gfSDFs of different compositions were studied in terms of APIs release from the matrix, solid-state characteristics, gellification properties and gfSDFs resistance to mechanical stress...

BACKGROUND: Diabetic foot ulcers (DFU) are a major complication in diabetics. Impaired microvascular reactivity is a major contributor to the development of DFU and has been traditionally quantified by time-domain or frequency-domain measures of skin blood flow (SBF). These measures, however, are unable to characterize the changes of nonlinear dynamics of SBF associated with diabetes and peripheral neuropathy. OBJECTIVE: The objective of this study was to investigate altered nonlinear dynamics of skin blood flow in the plantar foot of diabetics with peripheral neuropathy...

Exposure of the organism to a hostile stimulus results in a series of coordinated reactions that aim to avoid the aversive effect and maintain or restore homeostasis of the organism. In response to noxious stimuli corticotropin-releasing factor (CRF), the primary mediator of stress responses is released from the paraventricular nucleus resulting in activation of the hypothalamic-pituitary-adrenocortical axis and coordination of the endocrine, autonomic, behavioral and immune responses to stress. Several other neuropeptides, released in a coordinated way are also involved in the regulation of the stress response...

Crohn's disease and ulcerative colitis, known together as inflammatory bowel diseases (IBDs), and celiac disease are the most common disorders affecting not only adults but also children. Both IBDs and celiac disease are associated with oxidative stress, which may play a significant role in their etiologies. Reactive oxygen species (ROS) such as superoxide radicals (O2•(-)), hydroxyl radicals (•OH), hydrogen peroxide (H2O2), and singlet oxygen ((1)O2) are responsible for cell death via oxidation of DNA, proteins, lipids, and almost any other cellular constituent...

The presence of chronic inflammation in the colonic mucosa leads to an increased risk of cancer. Among proteins involved in the regulation of mucosal inflammation and that may contribute both to structural damage of the intestinal mucosa and to intestinal carcinogenesis, there are myeloperoxidase (MPO) and vanins. The infiltration of colonic mucosa by neutrophils may promote carcinogenesis through MPO, a key enzyme contained in the lysosomes of neutrophils that regulates local inflammation and the generation of reactive oxygen species (ROS) and mutagenic species...
