Most gastrointestinal stromal tumors (GISTs) arise from the proper muscle layer of the upper gastrointestinal (GI) tract and have a low malignant potential. They are sometimes accompanied by symptoms, but in most cases are detected by chance. Endoscopic surgery of subepithelial tumors in the upper GI tract has been actively performed, and its merits include the need for fewer medical devices co...

Mucosa-associated lymphoid tissue lymphoma (MALToma) is a subtype of B-cell non-Hodgkin's lymphoma, comprising ∼17% of all gastrointestinal (GI) tract lymphomas. It is associated with chronic inflammation and autoimmunity, for example Helicobacter pylori gastritis and Sjogren's syndrome, respectively. Approximately 50% of GI MALTomas occur in the stomach, with small bowel and colonic lesions be...

Background/Aims We evaluated the distribution of lower and upper gastrointestinal (GI) symptoms among individuals with irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC) in a nationwide survey. Methods Individuals (≥ 18 years of age) were identified from a nationwide sample of ＞ 70 000 United States adults. Participants completed the National Institut...

Aim: To investigate upper GI bleeding as a particular complication in chronic kidney disease patients. Material and methhod: 30 chronic kidney disease patients admitted to the Nephrology Department for upper gastrointestinal bleeding over a period of 5 years. Results: 16 patients were undergoing hemodialysis (53.3%) and 14 patients were not in a hemodialysis program. There were no patients unde...

A 21-year-old male reporting melena over one week is presented. Laboratory testing revealed severe anemia (Hgb 7 g/dL). Hyperpigmentation spots were present in the patient’s bucal mucosa and lower lip that arose during infancy. Three years ago, these lesions had raised the clinical suspicion of Peutz-Jeghers syndrome (PJS) and the patient had undergone an upper gastrointestinal (GI) endoscopy a...

To compare gastrointestinal (GI) problems among children with: (1) autism spectrum disorder (ASD), (2) developmental delay (DD) and (3) typical development (TD), GI symptom frequencies were obtained for 960 children from the CHildhood Autism Risks from Genetics and Environment (CHARGE) study. We also examined scores on five Aberrant Behavior Checklist (ABC) subscales comparing ASD children with...

Background : Gastrointestinal endoscopy is a procedure for diagnosis and treatment of GI abnormalities. It is one of the most common interventional medical procedures performed throughout the world. The authors studied anesthetic data as a basis for further research. Objective : To report and evaluate the choices and techniques, drug usuage and complications of anesthesia for GI endoscopy from ...

In [K1] and earlier in [K2], questions of the following type are considered: suppose a family (gi)i of matrices in some (algebraic) matrix group are given, with rational coefficients. What is the “typical” Galois group of the splitting field Ki of the characteristic polynomial of gi (defined as the field generated over Q by the roots of the characteristic polynomial)? Is this characteristic pol...
