(2003-11-01)
Gastroesophageal reflux disease (GERD) is an uncommon condition in chagasic esophagopathy not previously treated. In this report, a case of chagasic esophagopathy associated to GERD and complicated with Barrett's esophagus ...
Gene Mutations in Esophageal Mucosa of Chagas Disease Patients
(Int Inst Anticancer Research, 2009-04-01)
Background: Chagas disease patients with longstanding megaesophagus have a significantly increased risk for esophageal carcinoma. Materials and Methods: PCR-SSCP analysis and DNA sequencing of esophageal mucosa from Chagas ...
Chromosomal imbalances are uncommon in chagasic megaesophagus
(Biomed Central Ltd., 2010-02-17)
Background: Chagas' disease is a human tropical parasitic illness and a subset of the chronic patients develop megaesophagus or megacolon. The esophagus dilation is known as chagasic megaesophagus (CM) and one of the severe ...

kDNA gene signatures of Trypanosoma cruzi in blood and oesophageal mucosa from chronic chagasic patients
(Elsevier B.V., 2008-11-01)
Trypanosoma cruzi presents a high degree of intraspecific variability, with possible implications for the pathogenesis of Chagas disease. The aim of this study was to evaluate T cruzi kDNA minicircle gene signatures using ...
p53, p16 and Fhit Proteins Expressions in Chronic Esophagitis and Chagas Disease
(Int Inst Anticancer Research, 2008-11-01)
Background: Models have suggested esophageal carcinogenesis can result front the alteration of sequences, leading to esophagitis, atrophy, dysplasia, carcinoma in situ and invasive carcinoma. While numerous genetic alterations ...

(2009-03-01)
The present article relates the occurrence of Proventricular Dilatation Disease (PDD) in a 20 years old blue-fronted amazon parrot (Amazona aestiva). The bird was raised in captivity and was examined at the Ornitopathology ...
Cytogenetic alterations in chagasic achalasia compared to esophageal carcinoma
(Elsevier B.V., 2004-02-01)
Patients with chagasic achalasia (megaesophagus) are liable to have an additional 1.7-20% possibility of developing esophageal squamous cell carcinoma (ESCC). We applied a fluorescence in situ hybridization technique in ...
