Cowden syndrome is a rare autosomal dominant familial cancer syndrome with a high risk of breast cancer. The most important clinical features include carcinomas of the breast and thyroid, and hamartomatous polyps of the gastrointestinal tract. There are characteristic mucocutaneous features which allow early recognition of the disease and are generally present before internal malignancies devel...
Chlamydia muridarum is known to colonize in the gastrointestinal tract for long periods of time, which has been hypothesized to serve as a reservoir for spreading to the genital tract. To test this hypothesis, a luciferase-expressing C. muridarum was used to establish a long-lasting infection in the mouse gastrointestinal tract following either intragastric or intrarectal inoculations. In vivo ...
Duplication of the gastrointestinal tract occur any part alimentary from tongue to anus. Male have slightly more predominance than females. Gastrointestinal duplication will a varied presentation. Ileum and oesophagus are most commonly involved. Colonic is rare can present with diagnostic difficulties. has presence well developed coat smooth muscle, intimately attached in mesentric region show ...
There has been speculation that the ingestion of asbestos in food and drinking water may play some role in the etiology of cancer of the gastrointestinal (GI) tract. An important question in the evaluation of the possible human cancer risk associated with asbestos ingestion is whether fibers can penetrate into and through the GI tract in sufficient numbers to cause adverse systemic or local eff...
BACKGROUND Most patients with path_MMR gene variants (Lynch syndrome (LS)) now survive both their first and subsequent cancers, resulting in a growing number of older patients with LS for whom limited information exists with respect to cancer risk and survival. OBJECTIVE AND DESIGN This observational, international, multicentre study aimed to determine prospectively observed incidences of can...
background: gastrointestinal tract cancer (gi.c) is one of the common cancers in world‑wide. the incidence rate of it is different in various geographical regions. this study was performed to assess spatial clusters of the occurrence of gi.c in fars province. methods: in this cross‑sectional study, the new cases were 4569 cases from 2001 to 2009. the crude incidence rates were standardized base...
The aim of this study was to evaluate the effect of two different environments (Faroe Lake and Caspian Sea) on the accumulation of nickel and cadmium in gastrointestinal tissue. A total of 49 mullets collected and transported to the laboratory on Lake Faro and the Iranian shores of the Caspian Sea with ice. After extracting the contents of the gastrointestinal tract, the middle and near the end...
Haptoglobin (Hp) phenotypes were studied in 72 oesophageal and 104 gastric cancer patients and compared with 100 healthy controls to see if there is any association between oesophageal and gastric cancer and haptoglobin type. There was a significantly increased frequency of Hp 2-1 (59.7%) and Hp 2-2 (91.3%) in oesophageal and gastric cancer patients. Our results suggest that genetic factors pla...
BACKGROUND Upper gastrointestinal tract bleeding refers to blood loss within the intraluminal gastrointestinal tract from any location between the upper oesophagus to the duodenum at the ligament of Treitz. The onset and severity of blood loss varies widely. Acute gastrointestinal bleeding is a potentially life-threatening abdominal emergency that remains a common cause of hospitalization. Ther...
BACKGROUND Cell-free DNA (cfDNA) extracted from blood has become a clinically feasible biomarker in various types of cancer. However, the clinical significance of cfDNA in gastrointestinal (GI) tract cancer among Asian populations requires further investigation. RESULTS The median cfDNA copy number was highest in esophageal cancer, followed by colorectal cancer and gastric cancer, which were ...
