We studied the relationship between gastroduodenal inflammation and the presence of Campylobaeter pylori from biopsy specimens of the gastric mucosa in 91 patients with gastritis with or without ulcers and 9 controls, healthy or suffering from other diseases. 68 of the patients were positive for the presence of C. pylori in their gastric mucosa. C. pylori was confirmed bacteriohistological...
Before the introduction of endoscopy, four out of 720 cases of gastric cancer were diagnosed before the cancer had breached the muscularis propia, an incidence of 0.5%. Using endoscopy and endoscopic biopsy, 10 out of 101 cases of gastric cancer were diagnosed at this "early" stage, an incidence of 10%. Their clinical, morphological, and histological characteristics are compared with those of J...
We describe the first case of gastritis in a male Australian sea lion (Neophoca cinerea) in which members of the family Helicobacteraceae, particularly the genus Wolinella, were detected. The sea lion exhibited clinical signs of gastrointestinal disease, including abdominal pain, lack of appetite, and lethargy. Examination of one ileal and five gastric biopsy specimens collected over a 10-year ...
AIMS To determine the prevalence of Helicobacter pylori colonisation in the mouths of patients with H pylori gastritis. METHODS A nested polymerase chain reaction test for the 16S ribosomal RNA gene of H pylori was used on saliva, dental plaque, gastric juice and gastric biopsy specimens from patients attending a dyspepsia clinic. RESULTS Thirteen patients had histologically confirmed Helic...
Although there are general guidelines on endoscopic biopsy for diagnosing gastric neoplasms, they are predominantly based on outdated literature obtained with fiberscopes without analyses specific to tumor characteristics.This study aims to comprehensively characterize the contemporary endoscopic biopsy by determining the diagnostic yield across different lesion morphologies and histological st...
Twenty freshly resected stomach specimens, each containing an ulcerated carcinoma, were studied in an attempt to determine the best site for gastric biopsy. Using endoscopic biopsy forceps multiple biopsies were obtained from various sites around the ulcer. Carcinoma was detected with similar frequency in biopsies from the slough and from the rim of the ulcer. The positive biopsy rate was incre...
Objectives: Several biologics therapy reportedly regress gastric amyloid deposition in AA amyloidosis patients, but it is uncertain whether they can also regress renal amyloid deposition. We carried out serial renal biopsy to clarify the regression of amyloid deposition in kidney by biologics. Methods: After the diagnosis of AA amyloidosis was determined by gastric biopsy to rheumatoid arthriti...
Objectives: To compare doing brush cytology before and after biopsy. in the diagnosis of gastric malignancies Study Design: This prospective study included 7 4 cases referred to endoscopy clinic for suspected gastric lesions during a year (2013-2014). In 38 cases brush was done before and in ,36 cases it was done after biopsy. All the cytology and biopsy slides were randomly coded and reviewed ...
Ectopic breast tissue has the ability to undergo all the pathological changes of the normal breast, including breast cancer. Gastrointestinal metastasis of breast cancer is rarely observed and it is very difficult to differentiate gastric metastases from primary gastric cancer. We present a case of 52-year-old female, who suffered from abdominal pain. Physical examination showed a palpable mass...
Stool, gastric biopsy, and serum samples were collected from 22 subjects. DNA from stool was extracted, amplified, and hybridized with primers specific for the 16S rRNA gene of Helicobacter pylori. DNA from gastric biopsy specimens was analyzed similarly for comparison. Universal primers were used to confirm successful extraction of DNA from samples. Histologic, serologic, and DNA analyses were...
