Gastrointestinal tract conditions

Pneumatosis cystoides intestinalis is a rare and usually benign condition in which multiple thin-walled cysts develop in the submucosa or subserosa of the gastrointestinal tract. While usually asymptomatic, severe cases can result in pneumoperitoneum, which can be managed surgically or medically depending on circumstances.

Hereditary hemorrhagic telangiectasia is an autosomal dominant condition with an estimated prevalence of 1 in 5000. It is characterized by the presence of abnormalities of vascular structures, and may affect many organ systems, including the lungs, brain, spinal cord, gastrointestinal tract, and liver.

Eosinophilic gastrointestinal disorders are rare inflammatory conditions marked by eosinophilic infiltration of the gastrointestinal tract. Endoscopic manifestations vary from patient to patient. However, ulcerative lesion is a rare occurence.

Pneumatosis cystoides intestinalis (PCI) is an uncommon condition where cyst-like locules of gas are present in the submucosa or subserosa of the gastrointestinal tract. The majority of cases are benign and are associated with drugs such as chemotherapy agents or conditions including chronic obstructive airways disease.

Targeted colonic drug delivery systems are needed for the treatment of endemic colorectal pathologies, such as Crohn’s disease, ulcerative colitis, and colorectal cancer. These drug delivery vehicles are difficult to formulate, as they need to remain structurally intact whilst navigating a wide range of physiological conditions across the upper gastrointestinal tract.

Anastomotic leakage is the most important surgical complication following esophagectomy. A major cause of leakage is ischemia of the gastric tube that is used for reconstruction of the gastrointestinal tract.

Campylobacter spp. are a major cause of bacterial food-borne diarrhoeal disease. This mainly arises through contamination of meat products during processing. For infection, Campylobacter spp. must adhere to epithelial cells of the mucus layer, survive conditions of the gastrointestinal tract, and colonise the intestine of the host.

Only 10–30% of oesophageal and rectal adenocarcinoma patients treated with neoadjuvant chemoradiotherapy have a complete pathological response. Inflammatory and angiogenic mediators in the tumour microenvironment (TME) may enable evasion of anti-tumour immune responses.

Eleven Bacillus strains were isolated from foods and evaluated their probiotic potential and safety. Then study the effect of selected strains against pathogens, and on the population of pathogens in reconstituted skim milk (RSM).Seven strains from Bacillus sp. (3) and Bacillus subtilis (4) were selected which were grow in low pH 1.0 to 5.0 and tolerant bile salt 0.3 to 2%, highly resistant to simulated gastrointestinal tract conditions, and showed antimicrobial activity against Salmonella typhimurium ATCC20231 and Staphylococcus aureus ATCC25923.

The normal indigenous intestinal microflora consists of about 1015 bacteria that under physiological conditions reside mainly in the lower gastrointestinal tract. Bacterial overgrowth implies abnormal bacterial colonization of the upper gut, resulting from failure of specific defense mechanisms restricting colonization under physiological conditions.

This Report addresses in considerable detail the consequences of hot particles on and near the skin, in the eye, ear, respiratory system, and gastrointestinal tract. Limits for exposures from hot particles are recommended. If exposures are maintained below the recommended limits, few, if any, deterministic biological effects are expected to be observed, and those effects would be transient in nature. If effects from a hot-particle exposure are observed, the result is an easily treated medical condition involving an extraordinarily small stochastic risk.

Acute emergencies in gastroenterology are extraordinarily severe conditions with high morbidity and mortality. Particularly severe diseases include acute pancreatitis, a difficult course of non-specific intestinal inflammations manifested by toxic colon or acute intestinal obstruction, and even acutely developed intestinal pseudo-obstruction (Ogilvie’s syndrome) or variceal and non-variceal bleeding into the gastrointestinal tract.
