Metaplasia represents the process of transforming a well-differentiated adult tissue into another type of adult tissue. Pancreatic metaplasia of the gastric mucosa represents the process in which the normal mucosa of the stomach is replaced with pancreatic formations, which mimic the structure of
A survey of the histology of gastric biopsies in 501 dogs, consisting of 19 clinically healthy dogs and 482 vomiting dogs is presented. Whole stomachs of four young clinically healthy laboratory dogs were used as controls. Eleven percent of forceps biopsies were unsuitable for examination; all
Angiogenesis is part of the pathophysiology of myelofibrosis with myeloid metaplasia (MMM). PTK787/ZK 222584 (PTK/ZK) is a novel inhibitor of vascular endothelial growth factor receptors. Twenty-nine patients with MMM received a continuous dosing schedule of PTK/ZK doses of 500 or 750 mg twice daily
Ependymoma is a circumscribed glioma composed of uniform glial cells with bland nuclei in a fibrillary matrix. It is characterized by the presence of perivascular pseudorosettes. Unusual histopathological findings have rarely been reported in ependymomas, 0.5% of all diagnosed cases. Such unusual
BACKGROUND
Whether plasma ghrelin/obestatin levels are associated with Helicobacter pylori (H. pylori) infection, subtypes of functional dyspepsia (FD), and gastric mucosal histology has not yet been established in elderly patients.
OBJECTIVE
The aim of this study was to determine whether plasma
BACKGROUND
Active gastritis, atrophic gastritis (AG) and intestinal metaplasia are lesions associated with Helicobacter pylori (H. pylori) infection in adults.
OBJECTIVE
To assess the prevalence of chronic gastritis, its histological characteristics and clinical features in children.
METHODS
345
In a group of 12 patients with reflux esophagitis resistant to the medical treatment and normal LES pressure, gastric emptying and bile-gastric (B.G.) reflux (HIDA-CCK test) were determined. All of the patients had delayed gastric emptying associated in seven with high levels of B.G. reflux. Two of
We report an eight years female child of symptomatic giant Rathke's cleft cyst extending from right parasellar, paraventricular region to right fronto-temporo-parietal cortical surface which is an unusual site for Rathke's cyst. MRI Brain scans of patient who presented with diminution of vision in
Fourteen patients were selected with advanced superficial chronic gastritis (grade II), marked chronic gastritis with partial atrophy (grade III), or chronic gastritis with total atrophy in which intestinal metaplasia was observed (grade IV). Azathioprine was administrated to all of them for periods
Gastric hyperplastic polyps in organ transplant recipients have been recently described; however, the clinical significance of hyperplastic polyps in this setting remains unclear. The aim of this study is to further characterize the clinical presentation and histopathology of gastric hyperplastic
A 10-y-old Irish Setter was presented with a history of recurrent episodes of regurgitation and vomiting, with more recent development of tachypnea. Megaesophagus had been diagnosed in the dog 2 y prior to this presentation. A solitary polypoid mass present immediately rostral to the lower
BACKGROUND
Endoscopic radiofrequency ablation (ERFA) is being evaluated as definitive treatment for patients with Barrett's esophagus (BE). Guidelines have yet to be developed for the application of this technology to patients with ultralong-segment BE (ULBE, > or = 8 cm). This study reports a
It is now recognised that Helicobacter pylori, like most enteric infections, is mainly acquired in childhood. Adults rarely become infected, with seroconversion rates varying between 0.33and 0.5% per person year. The age at which children are most likely to become infected is still unclear, but
Background: The Sydney system for assessing inflammatory lesions in the gastric mucosa is based on endoscopic and histological examinations. This study aimed to apply the Sydney system to diagnose gastritis in dogs. The study also
Neurenteric cysts are extremely rare congenital anomalies, often presenting in the first 5 years of life, and are caused by an incomplete separation of the notochord from the foregut during the third week of embryogenesis. They are frequently accompanied with spinal or gastrointestinal
