Cystic fibrosis has historically been considered a pulmonary disease, but with the increasing life expectancy of these patients, gastrointestinal manifestations are becoming more important. Furthermore, nutritional status is closely linked to pulmonary function and, thus, overall mortality. This article discusses gastrointestinal manifestations (which involve nutritional, pancreatic, hepatobili...

Gastrointestinal problems account for a significant proportion of general practitioners' workload, and gastrointestinal cancers, taken together, make up the largest group of malignancies. Approximately 10% of consultations in general practice in the UK are for gastrointestinal symptoms or problems, split roughly equally between the upper and lower gastrointestinal tract. Gastroenterology repres...

This paper describes the journey of a patient with coeliac disease who presented with overt obscure gastrointestinal bleeding. Upper and lower gastrointestinal endoscopy did not reveal a source of bleeding, but an abdominal CT scan detected abnormal lymphadenopathy and a wireless capsule endoscopy diagnosed a jejunal tumour, which was surgically removed. Gastrointestinal bleeding is rare in cel...

Common causes of lower gastrointestinal bleeding include diverticular disease, vascular disease, inflammatory bowel disease, neoplasms, and hemorrhoids. Lower gastrointestinal bleeding of appendiceal origin is extremely rare. We report a case of lower gastrointestinal bleeding due to angiodysplasia of the appendix. A 72-year-old man presented with hematochezia. Colonoscopy showed active bleedin...

The anatomy and physiology of the ferret is different than cats or dogs. Gastrointestinal disease has is usually manifested by diarrhea, weight loss, and anorexia. The role of Helicobacter mustelae has been studied as a model for gastrointestinal disease in other species. The hedgehog and sugar glider are essentially insectivore/omnivores but have the simple stomach and intestinal tract more si...

Lower gastrointestinal hemorrhage accounts for approximately 20% of gastrointestinal hemorrhage. The most common causes of lower gastrointestinal hemorrhage in adults are diverticular disease, inflammatory bowel disease, benign anorectal diseases, intestinal neoplasias, coagulopathies and arterio-venous malformations. Hemangiomas of gastrointestinal tract are rare. Mesenteric hemangiomas are al...

BACKGROUND The prevalence and nature of arrhythmias in horses following general anaesthesia and surgery is poorly documented. It has been proposed that horses undergoing emergency surgery for gastrointestinal disorders may be at particular risk of developing arrhythmias. Our primary objective was to determine the prevalence and nature of arrhythmias in horses following anaesthesia in a clinical...

BACKGROUND Previous research has shown that dysphagia and gastrointestinal problems occur frequently in carriers of the m.3243A>G mutation; however, the exact frequency and severity have not been determined. We hypothesise that adult carriers have an increased risk for malnutrition. METHODS In this observational study we evaluated the presence of gastrointestinal problems and dysphagia in 92 ...

bacteria usually cause disease in the gastrointestinal tract by colonization and growth in the gastrointestinal tract, where the micro organisms may invade the tissues of host or secretion of an exotoxin that is performed in food and then ingested by the host, examples of second group include: staphylococcal, bacillus cereus, clostridial (c.botulinum and c.perfringens type a) toxin. in this stu...
