25. Aplicação da técnica de pesquisa do linfonodo sentinela no estadiamento do carcinoma gástrico
Gastric adenocarcinoma patients has lymph node metastases as an independently prognosis factor. Radical limphadenectomy can improve survival but also can increase surgical morbidity. As a principle, sentinel node navigation surgery (SNNS) could avoid unnecessary lymphadenectomy without compromising the prognosis. In this study 24 patients with gastric adenoc

27. Reinfecção pelo Helicobacter pylori em pacientes brasileiros com úlcera péptica, em seguimento de 5 anos / Helicobacter pylori reinfection in brazilian patients with peptic ulcer disease, a five year follow-up
Introdução: A reinfecção pelo Helicobacter pylori em países em desenvolvimento parece ser maior do que nos países desenvolvidos. O retratamento da bactéria e o controle periódico de cura são necessários, quando elevadas taxas de reinfecção são verificadas. O objetivo do trabalho foi determinar a taxa anual de reinfecção, em pacientes brasileir

28. Evaluation of Helicobacter pylori genotype in the oral cavity / Pesquisa da cepa de Helicobacter pylori na cavidade bucal
Helicobacter pylori (H. pylori) infection is very prevalent in Brazil, infecting almost 65% of our population, being associated with peptic ulcer disease, gastric cancer, lymphoma and functional dyspepsia. The aim of this study was to evaluate the presence of this bacterium in the oral cavity of epigastric pain syndrome (functional dyspepsia) patients and as

29. Aspectos endoscópicos no manejo da úlcera péptica gastroduodenal
Bleeding remains a common and a potential lethal complication for peptic ulcer disease. Multidisciplinary approach by endoscopists, surgeons and intensive care physicians is necessary to improve results for this severe complication. In this article we intend to introduce surgeons and intensive care physicians to endoscopic concepts and maneuvers commonly use

30. 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

31. Correlation between Helicobacter pylori infection, gastric diseases and life habits among patients treated at a university hospital in Southeast Brazil
Helicobacter pylori is considered a significant agent in the development of various gastric diseases. However, the diseases caused by this bacterium are known as being multi-factorial, with the genotype, immune system and life habits of the host playing important roles in the establishment of the clinical outcome. Also, H. pylori exhibit a high degree of gen

Implicação de genes da zona de plasticidade e da ilha de patogenicidade cag (PAIcag) de Helicobacter pylori no desenvolvimento de doenças gastroduodenais / Implication of Helicobacter pulori plasticity region and cag pathogenicity island (cagPAI) genes on the development of gastroduodenal diseases
Helicobacter pylori is a Gram-negative, spiral-shaped, flagellated, micro-aerophilic bacterium, included in the Helicobacteraceae family, which infects the human stomach cronically. H. pylori infection has a worldwide distribution and is associated with the development of several gastroduodenal diseases, such as gastritis, peptic ulcer disease (PUD) and its

33. Comparação de dois regimes terapêuticos no retratamento da infecção por h. pylori: ensaio clínico aberto, prospectivo e aleatorizado
H. pylori treatment failure is a growing problem in daily practice. Aim: to evaluate and compare the efficacy of two new regimes as second-line options in a randomized, prospective study. Methods: Patients previously submitted, without success, to clarithromycin-based regimes were included. 13C-urea breath test (UBT) was performed in all patients. The patien

Avaliação da relação entre o surgimento da esofagite erosiva e a cepa do Helicobacter pylori erradicado" / Clinical and endoscopic study in patients who have peptic gastroduodenal ulcer, 1 year after the eradication from Helicobacter pylori. Valuation of the relationship between the appearence of erosive esophagitis and the strains from the eradicated Helicobacter pylori
Atualmente, muitas são as diretrizes na literatura quanto à influência do Helicobacter pylori na Doença do Refluxo Gastroesofágico. Alguns autores acreditam que o H. pylori poderia ter um efeito protetor para o desenvolvimento na DRGE e outros até mesmo concluem que o agente possa ser um fator agravante na doença. Muitas publicações nos alertam para

36. 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
