BACKGROUND: Numerous etiologies are implicated in the complications of diabetes. A link between diabetes and the predisposition to certain cancers, including colon cancer, has been established during the last decade. However, the relationship between fecal occult blood test (FOBT), a screening method used principally for detection of colon cancer, and diabetes has not been explored. METHODS: We investigated the association of positive FOBT with HbA1c of 5.70-6.49% (prediabetes) and HbA1c of ≥6...

BACKGROUND: Gastric foveolar hyperplastic polyps (GFHPs) are common findings in clinical practice. GFHPs commonly arise in a background of chronic atrophic gastritis, including autoimmune gastritis (type A gastritis), and have a potential risk of malignant transformation. CASE PRESENTATION: In 2005, a 55-year-old Japanese woman underwent upper endoscopy at another hospital and was found to have a pedunculated polyp (10 mm in diameter) on the greater curvature of the lower gastric body...

Wegener's granulomatosis is an uncommon inflammatory disease that manifests as vasculitis, granulomatosis, and necrosis. It usually involves the upper and lower respiratory tracts and kidneys. Although it may essentially involve any organ, gastrointestinal (GI) involvement is notably uncommon. A 20-year-old male patient presented with epigastric pain, vomiting, hematemesis, and melena. On physical examination, he was pale. There was no abdominal tenderness or organomegaly. Upper GI endoscopy revealed dark blue-colored infiltrative lesions in prepyloric area...

Gastrointestinal xanthomas are infrequent non-neoplastic lesions characterized by the accumulation of foam cells in the lamina propria. They are commonly seen in association with dyslipidemia, chemotherapy or radiotherapy, and infections in immunosuppressed patients. However, no clear connection to hyperlipidemia has been found. They occur more frequently in the stomach, and are very rare in the small bowel and esophagus. We identified all cases of non-gastric xanthoma or xanthomatosis reported in the English literature by searching the PubMed database and retrospectively reviewed the clinical, endoscopic, and histopathologic features of the 11 cases of non-gastric gastrointestinal xanthomas diagnosed in our hospital...

Bmps are morphogens involved in various gastric cellular functions. Studies in genetically-modified mice have shown that Bmp disruption in gastric epithelial and stromal cell compartments leads to the development of tumorigenesis. Our studies have demonstrated that abrogation of gastric epithelial Bmp signaling alone was not sufficient to recapitulate the neoplastic features associated with total gastric loss of Bmp signaling. Thus, epithelial Bmp signaling does not appear to be a key player in gastric tumorigenesis initiation...

Gastric polyps occur in 1-4 % of patients undergoing gastroscopy. Although most are sporadic, some gastric polyps are part of an underlying hereditary syndrome. Gastric polyps can be seen in each of the well-known gastrointestinal polyposis syndromes, but also in Lynch syndrome and in several rare not primarily gastrointestinal syndromes. In addition, Gastric Adenocarcinoma and Proximal Polyposis of the Stomach (GAPPS) is a recently described heritable syndrome characterized by isolated gastric polyposis and risk of gastric cancer...

Russell body gastroenteritis has been reported as a reactive inflammatory process in most cases and many of the reports were from the upper gastrointestinal tract, especially the stomach, which may be associated with Helicobacter pylori infection and rarely associated with gastric carcinoma. Russell body containing Mott cells have been rarely seen in Barrett's esophagus and duodenum, and only 2 cases have been reported in colon, including a transplant patient with diarrhea and a rectal tubulovillous adenoma...

We report the case of a 55-year-old woman with a tumor in the greater curvature of the upper gastric body. The tumor was incidentally found on an upper gastrointestinal X-ray series performed during a routine medical examination. Whereas endoscopy revealed a gastric submucosal tumor (SMT), endoscopic ultrasonography demonstrated a heterogeneous tumor with small, cystic, hypoechoic spots originating from the second layer. The patient was clinically asymptomatic, with no contributory family history or abnormal laboratory data...

Inflammatory fibroid polyp of the gastrointestinal tract is a rare, benign neoplasm, most frequently located in the gastric antrum. Symptoms depend on the location and the size of the lesion. Biopsies are limited for the diagnosis of inflammatory fibroid polyps and diagnosis may not be possible until resection. The authors present a case of a 55-year-old woman, presenting with an upper gastrointestinal bleeding due to a large gastric inflammatory fibroid polyp imitating a gastrointestinal stromal tumor.

BACKGROUND AND STUDY AIMS: Gastric hyperplastic polyps (GHP) have been identified as a cause of transfusion-dependent iron-deficiency anemia (tIDA) and transfusion-dependent gastrointestinal bleeding and are commonly identified in the setting of cirrhosis. The aim of this study was to assess the effectiveness of endoscopic resection (ER) for the treatment of tIDA or gastrointestinal bleeding due to GHP in patients with and without liver disease. PATIENTS AND METHODS: This was a single-center retrospective review...

Cowden syndrome (CS) is a rare autosomal dominant disorder characterized by multiple hamartomas in various tissues and cancers (breast, thyroid, and endometrium). We report CS of the esophagus and gastrointestinal tract that was incidentally detected by positron emission tomography/computed tomography (PET/CT) at postoperative surveillance in an endometrial cancer patient. PET/CT showed mildly increased FDG uptake along the entire esophagus and stomach. Upper GI endoscopy and histologic examination revealed glycogenic acanthosis of the esophagus and several hundred gastric polyps...

For the past few years adipokines have been a center of appreciation and interest. They are biologically active molecules causing pleiotropic effects. They assist in angiogenesis, adipose tissue metabolism and inflammation, and modulate tissue sensitivity for insulin. Adipokines are produced in adipose tissue, so an abnormal quantity of this tissue leads to impaired levels of these factors. Because of their different concentrations in various conditions, it would be plausible to use them as markers for individual conditions, such as obesity, type 2 diabetes mellitus, pancreatitis, gastric cancer, lung cancer or colon cancer...

Serrated polyps are classified into 3 distinct types: hyperplastic polyp, sessile serrated adenoma, or transitional serrated adenoma. A serrated adenoma is a precursor lesion for colorectal carcinoma. Serrated polyps are commonly found in the colorectum but have rarely been described in other parts of the gastrointestinal tract. Serrated adenomas in the small intestine may represent aggressive lesions with high malignant potential, according to some reports. A 66-year-old man with no significant medical history underwent esophagogastroduodenoscopy (EGD) for general examination...

One of the main tasks for pathologists when evaluating gastric biopsies from patients with portal hypertensive gastropathy (PHG) is to examine whether there is increased mucosal vasculature as suggested by endoscopy. However, the full spectrum of pathology findings in patients with portal hypertension (pHTN) is largely unknown. We systematically characterized the endoscopic and pathologic features in gastric biopsies from pHTN patients (study group) and compared with those from patients without pHTN (control group)...

Inflammatory fibroid polyps (IFPs) are rare non-neoplastic and proliferating submucosal lesions of the gastrointestinal tract. The classic IFP, which was first described by Vanek, consists of prominent blood vessels and is characterized by a heavy inflammatory infiltrate, which is rich in eosinophilic granulocytes. The clinical presentation depends on the size and location. Inflammatory fibroid polyps cannot be differentiated from malignancy without histological examination. We report a case of IFP in the stomach that mimicked a primary gastric malignancy showing an increased F-FDG uptake...

γ-aminobutyric acid (GABA) receptors, responding to GABA positive allosteric modulators, are present in the freshwater polyp Hydra vulgaris (Cnidaria, Hydrozoa), one of the most primitive metazoans to develop a nervous system. We examined the occurrence and distribution of GABAA receptor subunits in Hydra tissues by western blot and immunohistochemistry. Antibodies against different GABAA receptor subunits were used in Hydra membrane preparations. Unique protein bands, inhibited by the specific peptide, appeared at 35, 60, ∼50 and ∼52 kDa in membranes incubated with α3, β1, γ3 or δ antibodies, respectively...

BACKGROUND: Studies with latest technologies such as endoscopy with magnification and chromoendoscopy showed that various endoscopic aspects are clearly related to infection by Helicobacter pylori (HP). The description of different patterns of erythema in gastric body under magnification of images revived interest in identifying these patterns by standard endoscopy. AIM: To validate the morphologic features of gastric mucosa related to H. pylori infection gastritis allowing predictability of their diagnosis as well as proper targeting biopsies...

BACKGROUND: We recently observed patients with chronic liver disease (CLD) or chronic reflux symptoms (CRS) who developed gastric polyps (GPs) while undergoing surveillance gastroscopies for the detection of esophageal varices or Barrett's esophagus, respectively. OBJECTIVES: To identify risk factors for GP growth and estimate its growth rate. METHODS: GP growth rate was defined as the number of days since the first gastroscopy (without polyps) in the surveillance program, until the gastroscopy when a GP was discovered...

BACKGROUND AND STUDY AIMS: Gastric cancer is highly prevalent in Kashmir, as are lower gastrointestinal (LGI) malignancies. Colonic cancer, gastric cancer, and coeliac disease are the most important gastrointestinal (GI) causes of iron deficiency anaemia (IDA) worldwide. Approximately 9% of patients with IDA present with a suspicious lesion in the GI tract upon examination. However, the absence of GI symptoms and a possible lesion accounting for blood loss in IDA have not been studied in this zone with a high prevalence of GI malignancy...
