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 physi...

We present a case of a 56-year-old man with 3 synchronous gastric tumors. The patient presented with melena, and 3 gastric abnormalities were detected on gastroduodenoscopic examination, including a small ulcerative lesion in the gastric antrum, a submucosal mass in the gastric body, and severe erosion in the fundus. Histological examination of biopsy samples yielded respective diagnoses of gas...

Since the means of culturing Helicobacter pylori may not be available in some laboratories, prolonging the survival of this organism during transportation is a major concern in terms of improving detection rates. A selective transport medium was evaluated for the preservation of H. pylori from 254 gastric biopsy specimens collected from a rural area in China where culturing is not feasible. Gas...

BACKGROUND/AIMS Endoscopic resection (ER) is a well-established treatment modality for gastric epithelial neoplasm. However, there is a discrepancy between forceps biopsy and ER specimen pathology, including a negative pathologic diagnosis (NPD) after ER. It has been suggested that pit dysplasia (PD) is a subtype of gastric dysplasia, and the aim of this study was to assess the significance of ...

A gastric juice-based real-time polymerase chain reaction (PCR) assay was established to identify Helicobacter pylori infection, clarithromycin susceptibility and human CYP2C19 genotypes and to guide the choice of proton pump inhibitor (PPI), clarithromycin and amoxicillin treatment for tailored H. pylori eradication therapy. From January 2013 to November 2014, 178 consecutive dyspeptic patient...

Gastric biopsy specimens from 283 patients with ulcer and non-ulcer dyspepsia attending five gastroenterology clinics in the northern region of the United Arab Emirates (UAE) were tested by the agar gel test (n = 115) or the ultra-rapid endoscopy room test (n = 168) for the presence of Helicobacter pylori urease. Results were compared with a histological technique using the Romanowsky type (Dif...

Mucosal and systemic immunologic recognition of cagA by Helicobacter pylori-infected individuals is associated with peptic ulcer disease; however, in the laboratory, expression of cagA is subject to artificial conditions which may not accurately reflect the conditions in host tissues. Gastric antral and body biopsy specimens and serum for anti-H. pylori immunoglobulin G serology were obtained f...

The synchronous occurrence of primary renal cell carcinoma with gastric cancer is very rare. We report a case of 41 year old male who presented on 05/07/2011 to M S Ramaiah hospital, Bangalore with history of fever, pain abdomen and malena. Ultrasound abdomen and pelvis showed large heterogenous mass arising from the upper pole of left kidney. Computed tomography of the abdomen showed left rena...
