1. The role of high sensitive C-reactive protein and histopathological evaluation in chronic gastritis patients with or without Helicobacter pylori infection
Abstract Purpose: To evaluate serum levels of high-sensitivity C-reactive protein (hs-CRP) in chronic gastritis patients to predict Helicobacter pylori (HP) infection, inflammatory activity, and precancerous lesions. Methods: A total of 811 patients with upper gastrointestinal symptoms and histopathological diagnosis of chronic gastritis were enrolled in

2. [ARTICLE PARTIAL RETRACTION] PREVALENCE OF HELICOBACTER PYLORI INFECTION IN DYSPEPTIC PATIENTS AND ITS ASSOCIATION WITH CLINICAL RISK FACTORS FOR DEVELOPING GASTRIC ADENOCARCINOMA
RESUMO CONTEXTO: No Brasil, particularmente nas áreas mais pobres, a prevalência da infecção por Helicobacter pylori pode variar até 90%. Esses índices aumentam com o envelhecimento da população e são distintos entre as diferentes regiões do país. Podendo manifestar diferentes sintomatologias, essa infecção está diretamente relacionada com o

3. Oral and systemic manifestations in HIV-1 patients
INTRODUCTION: This study aimed to estimate the prevalence of the most frequent oral and systemic manifestations in human immunodeficiency virus-1 (HIV-1)-positive patients. METHODS: The study was conducted on 300 HIV-1 patients attending the Reference Unit Specialized in Special Infectious Parasitic Diseases in Belém, Pará, Brazil. RESULTS: The most preva

4. Dermatomyositis: analysis of 109 patients surveyed at the Hospital das Clínicas (HCFMUSP), São Paulo, Brazil
BACKGROUND: Dermatomyositis affects striated muscles, skin and other organs. OBJECTIVE: To characterize the disease from January 1992 to December 2002, assessing its classification, cutaneous and systemic manifestations, and also laboratory results, therapeutic and prognostic findings compared to those in the literature. METHODS: Data were obtained from

5. Differences in virulence markers between Helicobacter pylori strains from the Brazilian Amazon region
Introduction This study compares virulence markers of Helicobacter pylori isolated from patients in 2 cities in the Brazilian Amazon. Methods The study analyzed 168 patients with chronic gastritis from Belém and 151 from Bragança, State of Pará, Brazil. Levels of bacterial DNA associated with cagA and vacA alleles were checked by PCR, and hematoxylin-e

6. cagE as a biomarker of the pathogenicity of Helicobacter pylori
IntroductionHelicobacter pylori infection is associated with gastro-duodenal diseases. Genes related to pathogenicity have been described for H. pylori and some of them appear to be associated with more severe clinical outcomes of the infection. The present study investigates the role of cagE as a pathogenicity biomarker of H. pylori compare it to cagA, vacA

7. Evaluation of diagnostic methods for the detection of Helicobacter pylori in gastric biopsy specimens of dyspeptic patients
Helicobacter pylori infects nearly 50% of the world's population. This microorganism is accepted as the most important agent of gastritis and as a risk factor for peptic ulcer disease and gastric adenocarcinoma. Currently many diagnostic methods exist for detecting H. pylori, however they all have limitations, thus it is recommend a combination of at least t

8. ABO blood groups and Helicobacter pylori cagA infection: evidence of an association
Diseases resulting from Helicobacter pylori infection appear to be dependent on a host of genetic traits and virulence factors possessed by this microorganism. This paper aimed to investigate the association between the ABO histo-blood groups and H. pylori cagA infections. Genomic DNA samples (n = 110) of gastric biopsies obtained from patients with endoscop

10. Prevalência de manifestações esofagogastroduodenais em pacientes com HIV/Aids, submetidas à endoscopia digestiva alta, no Hospital Universitário de Brasília
With aim of characterize the esophagic, gastric and duodenal manifestations among patient with AIDS submitted to upper digestive endoscopy in the University Hospital of Brasília, we accomplished a transverse descriptive study. There were included all the patients with confirmed diagnosis of HIV infection submitted to upper endoscopy among the period of apri

11. Alterações gástricas em potros submetidos ao estresse do desmame.
This study evaluated 20 160-day-old foals half-bred Brasileiro de Hipismo, raised in Florestal area, state of Minas Gerais, Brazil, born between December 2003 and March 2004. The group was homogeneous, constituted of 12 fillies and 8 colts, 85% of them originated from the same stallion. The foals were submitted to abrupt artificial weaning, aiming to produce

12. Clinical and pathological importance of vacA allele heterogeneity and cagA status in peptic ulcer disease in patients from North Brazil
We have examined the prevalence of gene cagA and vacA alleles in 129 patients, 69 with gastritis and 60 with peptic ulcer diseases from North Brazil and their relation with histopathological data. vacA and cagA genotype were determined by polymerase chain reaction. Hematoxylin-eosin staining was used for histological diagnosis. 96.6% of the patients were col
