Tuberculose em 228 casos de autópsias
Feitosa, Priscilla Mariana Freitas Aguiar; Ferreira, Márcia Valéria Pitombeira; Silveira, Renan Siebra Capibaribe; Queiroz, Thamiris Silva deObjectives: Tuberculosis is the main cause of death by a single infectious agent in the world. However, few studies have been published about the anatomopathological aspects of tuberculosis (TB) in the organism as a whole. The objective of this article is to analyze the anatomopathological characteristics of deceased patients diagnosed with tuberculosis revealed by autopsy and their relationship with epidemiolo...
Necrópsia: valor diagnóstico
Ferreira, Márcia Valéria Pitombeira; Mendes, Venulda Helena Santos; Camurça, Tainah Braga; Lemos, Luanna de Queiroz; Silva, Oálene GonçalvesIntrodução: a necrópsia garante a acurácia estatística de mortalidade, esclarece mortes não explicadas, é fonte de aprendizado, de pesquisa e controle de qualidade hospitalar. Objetivos: verificar a frequência de necrópsias no Departamento de Patologia e Medicina Legal da Universidade Federal do Ceará (DPML/UFC), avaliar a eficácia diagnóstica da necrópsia, concordância e discordância entre o diagnóstico clínic...
Characterization of gastric cardia tumors : differences in Helicobacter pylori ...
Costa, Débora Menezes da; Pereira, Eliane dos Santos; Silva- Fernandes, Isabelle Joyce de Lima; Ferreira, Márcia Valéria PitombeiraBackground Gastric cancer results from a multifactorial process and is one of the most common causes of death worldwide. These tumors can arise in the distal stomach (non-cardia) and in the cardia region, presenting different characteristics and frequency of occurrence worldwide. Aims To search for differences between tumors of dif- ferent locations that could explain the presence of cardia tumors, considering ...

Differential expression of MYC in H. pylori-related intestinal
Fernandes, Isabelle Joyce de Lima Silva; Alves, Markênia Kélia Santos; Lima, Valeska Portela; Lima, Marcos Antônio Pereira deEvidence suggests that the carcinogenic process guided by Helicobacter pylori is related to the expression of cell cycle and apoptosis proteins as BCL-2, BAX, and MYC. However, the literature is conflicting regarding the expression frequency in the histological subtypes and did not consider cagA gene presence. To investigate the expression of these proteins considering the histological subtypes of gastric cance...
The relationship between Helicobacter pylori genes cag E and vir B11 and gastri...
Lima, Valeska Portela; Lima, Marcos Antonio Pereira de; Ferreira, Márcia Valéria Pitombeira; Barros, Marcos Aurélio Pessoaackground: The association between Helicobacter pylori gene diversity and gastric cancer has been poorly reported, although it is one of the important ways to explain the gastric pathogenesis. The aim of this study was to investigate the frequency of cag E and vir B11 genes in H. pylori isolated from patients with gastric cancer and to analyze the histology profiles. Materials and methods: The presence of H. py...
p27 KIP1 expression in gastric cancer : differential pathways in the histologic...
Alves, Markênia Kélia Santos; Lima, Valeska Portela; André, Ângela Rosa; Ferreira, Márcia Valéria Pitombeira; Barros, Marcos Aurélio PessoaObjective. Decreases in p27 KIP1 and C-MYC expression have been associated with Helicobacter pylori infection. Furthermore, C-MYC seems to be a transcriptional repressor of p27 KIP1 . Therefore, in a series of gastric adenocarcinomas we studied the association of p27 KIP1 expression with H. pylori genotype ( vac A, cag A, cag E and vir B11) and the involvement of C-MYC in this process. Material and methods. Exp...

Lima, Valeska Portela; Lima, Marcos Antonio Pereira de; André, Ângela Rosa; Ferreira, Márcia Valéria Pitombeira; Barros, Marcos Aurélio PessoaAIM: To investigate the interrelationship between H pylori and Epstein-Barr virus (EBV) infection in the gastric carcinogenesis having in focus the p53 mutation and the c-Myc, Bcl-2 and Bax expression. METHODS: seventy-one gastric carcinoma tissues were assessed by polymerase chain reaction (PCR) for H pylori and in situ hybridization for EBV. c-Myc, Bcl-2 and Bax expression were detected by immunohistochemistr...
