1. Estudo inter e intra observadores da reprodutibilidade do diagnóstico histológico da gastrite crônica, de acordo com o sistema Sydney atualizado
Objectives: To investigate the reproducibility of chronic gastritis histological diagnosis according to the updated Sydney system, in the working conditions of our environments pathology laboratories. Methods: We studied 168 dyspeptic patients from whom were obtained gastric endoscopic biopsies from the five locations recommended by the protocol above.The sl

2. Helicobacter pylori and idiopathic thrombocytopenic purpura / Helicobacter pylori em pacientes com purpura trombocitopenica idiopatica
Helicobacter pylori is a gram-negative bacterium that is related to the development of gastric and extragastric diseases. Gastric diseases include gastric cancer, chronic gastritis, peptic ulcer and MALT lymphoma. Extragastric diseases include iron deficiency anemia and some auto-immune conditions such as reumathoid arthritis and idiopathic thrombocytopenic

3. Endoscopic and histopathologic evaluation of the excluded stomach after bariatric surgery / Avaliação endoscópica e histopatológica do estômago excluso após cirurgia bariátrica
The surgical treatment for morbid obesity is the only modality that in the long term obtains the supported loss of weight and maintenance. Vertical banded Roux-en-Y gastric bypass is the most used technique worldwide and in Brazil. Through this technique, the stomach is divided in two assimetrical pouchs, one vertical and tubular with about 5 cm of extension

4. Dermatomyositis: analysis of 109 patients surveyed at the CHSPU / Dermatomiosite: estudo de 109 pacientes avaliados no HCFMUSP
Dermatomyositis is a chronic idiopathic inflammatory disorder which affects the striated skeletal muscles, the skin, and other organs. This present study aims at characterizing the patients who have been affected by this disease and were under treatment at HCFMUSP from January, 1992 to December, 2002 Its classification, the cutaneous and systemical manifesta

5. Helicobacter pylori (HP) gastric colozation and cytotoxin associated gene A (cagA) : relationship with cell proliferation and apoptosis / "Colonização gástrica por Helicobacter pylori associada à citotoxina do gene A (cagA): relação com proliferação celular e apoptose"
HP, uma bactéria gram-negativa envolvida na patogênese do tecido gastroduodenal, foi classificada como carcinogênico classe I em 1994. Seus mecanismos são pouco entendidos, mas a presença da ilha de patogenicidade (PAI) é fator importante de virulência. PAI sugere aumento da proliferação celular, diminuindo a apoptose. A detecção do HP e da PAI (c

6. Gastrite alcalina de refluxo : estudo experimental sobre a etiopatogenia
The duodenogastric reflux is a phenomenon know around 100 years. In the beggining it was considered verified that the reflux caused inflamation on the gastric mucosa. Later the reflux gastritis was observed in patients submitted to gastrojejunostomy or gastrectomy. Since then, several clinical and experimental studies were realized to reach better knowledge

7. The pattern of involvement of the gastric mucosa in lymphocytic gastritis is predictive of the presence of duodenal pathology.
AIM: To determine whether the pattern of involvement of the gastric mucosa in lymphocytic gastritis is predictive of the presence or absence of duodenal pathology. METHODS: 50 cases (M:F, 26:24; median age 57 years) diagnosed as lymphocytic gastritis between 1986 and 1998 with concurrent duodenal (D2) biopsies were identified from a computer search of the pa

8. Animal and public health implications of gastric colonization of cats by Helicobacter-like organisms.
The bacterial genus Helicobacter contains a number of species which colonize the gastric mucosa of mammals. Natural and/or experimental gastric pathology has been correlated with colonization in humans and a wide variety of animal species. Historical reports in the literature suggest that a high percentage of cats are colonized by large, spiral, gastric heli

9. Induction of Follicular Gastritis following Postthymectomy Autoimmune Gastritis in Helicobacter pylori-Infected BALB/c Mice
Helicobacter pylori is the major causative agent of chronic antral gastritis and is thought to be involved in the pathogenesis of mucosa-associated lymphoid tissue lymphoma (MALToma) developing in the human stomach. The aim of this study was to clarify whether corporal autoimmune gastritis (AIG), which is known to decrease acidity due to destruction of parie

10. Bile reflux and intestinal metaplasia in gastric mucosa.
AIM: To determine associations between enterogastric bile reflux and gastric mucosal pathology. METHOD: A retrospective study using fasting gastric juice bile acid measurements and antral or prestomal biopsy specimens from 350 patients, 66 of whom had previously undergone surgery that either bypassed or disrupted the pyloric sphincter. RESULTS: Bile reflux w

11. Phenotypic Variation of Helicobacter pylori Isolates from Geographically Distinct Regions Detected by Lectin Typing
A total of 309 Helicobacter pylori isolates from 18 different countries were analyzed with a previously developed lectin typing system. The system was developed by using a proteolytic pretreatment to enhance the carbohydrate fraction of the sample. Four lectins from Ulex europaeus, Lotus tetragonolobus, Erythrina cristigali, and Triticum vulgaris were used t

12. Helicobacter pylori serology in patients with coeliac disease and dermatitis herpetiformis.
AIMS: To investigate whether Helicobacter pylori infection or autoimmune gastritis is responsible for the reported increase in gastric pathology and abnormalities of gastric function in patients with coeliac disease and dermatitis herpetiformis (DH). METHODS: Serum H pylori IgG antibodies were assayed by enzyme linked immunosorbent assay and intrinsic factor
