1. INVESTIGATION OF ENTEROCOCCUS FAECALIS POPULATION IN PATIENTS WITH POLYP AND COLORECTAL CANCER IN COMPARISON OF HEALTHY INDIVIDUALS
RESUMO CONTEXTO: O câncer colorretal é um dos cânceres mais comumente diagnosticados em todo o mundo. Um dos fatores envolvidos no desenvolvimento do câncer colorretal é a mudança na flora normal do intestino. OBJETIVO: O número médio de cópias de Enterococcus faecalis em pessoas com pólipos e pessoas com câncer colorretal foram avaliados em c

2. Colonoscopic findings in patients aged 50 years and older: a critical analysis of 1614 exams
RESUMO Introdução: A colonoscopia mostra-se útil no diagnóstico de diversas patologias. Ao permitir a visualização direta da mucosa, possibilita a tomada de medidas terapêuticas, como a remoção de pólipos, dilatação de estenoses e realização de biopsias. Tal método pode ser empregado também no rastreio do câncer colorretal, que atualmente r

3. CLINICAL, EPIDEMIOLOGIC, AND ENDOSCOPIC PROFILE IN CHILDREN AND ADOLESCENTS WITH COLONIC POLYPS IN TWO REFERENCE CENTERS
Objetivos - Conhecer a frequência, o perfil clínico, os achados endoscópicos, de crianças e adolescentes submetidos à colonoscopia em dois centros de referência em gastroenterologia e endoscopia pediátrica. Métodos - Foram avaliados e acompanhados pacientes com idade menor ou igual a 18 anos com diagnóstico de pólipos identificados à colonoscopi

4. Thymosin ß4 expression in colorectal polyps and adenomas
OBJECTIVE: Thymosin beta 4 (Tβ4) is a ubiquitous peptide that plays pivotal roles in the cytoskeletal system and in cell differentiation. Recently, a role for Tβ4 has been proposed in experimental and human carcinogenesis, including gastrointestinal cancer. This study was aimed at evaluating the relationship between Tβ4 immunoreactivity and the initial s

5. Are histological alterations observed in the gallbladder precancerous lesions?
INTRODUCTION: Gallbladder cancer, which is characterized by rapid progression and a poor prognosis, is a complex disease to treat. Unfortunately, little is known currently about its etiology or pathogenesis. A better understanding of its carcinogenesis and determining risk factors that lead to its development could help improve the available treatment option

6. Inflammatory and apoptosis pathway in ileal pouches of patients with ulcerative colitis and familial adenomatous polyposis / Estudo da atividade inflamatoria e apoptose em reservatorios ileais de doentes operados por polipose adenomatosa familiar e retocolite ulcerativa inespecifica
Ileal pouch-anal anastomosis is the surgical procedure of choice for patients with refractory ulcerative colitis (UC) and for familial adenomatous polyposis (FAP) with rectal polyps. Pouchitis is the most common complication in UC, while it is quite rare in FAP. Objective: Evaluate the inflammatory and apoptotic activity in endoscopically normal ileal pouch

7. Síndrome de Peutz-Jeghers: relato de caso
Peutz-Jeghers syndrome (PJS) is a dominant autosomal inherited disorder characterized by intestinal hamartomatous polyps in association with mucocutaneous melanocytic maculae. This syndrome is rare, and the frequency reaches from 1 in 60,000 to 1 in 300,000 people in the USA. The symptom presentations vary greatly in this disease. Some patients require minor

8. NEOPLASIAS COLORRETAIS: ASPECTOS EPIDEMIOLÓGICOS, ENDOSCÓPICOS E ANATOMOPATOLÓGICOS - ESTUDO DE SÉRIE DE CASOS
O carcinoma colorretal (CCR) é a segunda neoplasia mais freqüente na população mundial. A alta incidência do CCR e a diferença nos resultados do tratamento desta neoplasia, de acordo com o estádio da doença, justificam os esforços para o rastreamento, prevenção e detecção precoce. Objetiva-se neste estudo descrever os aspectos: epidemiológicos,

9. Intestinal polyps in the Nigerian African.
Intestinal polyps appear to be relatively rare in the African including Nigerians, South African Bantus, and Ugandans. Only 40 histologically confirmed cases were encountered over a period of ten years. Analysis of these cases reveals a preponderance (60%) of the non-neoplastic juvenile type of polyp. Neoplastic polyps were not encountered in any female pati

10. Morphological range of hyperplastic polyps and carcinomas arising in hyperplastic polyps of the stomach.
A morphological range of 67 hyperplastic polyps was studied. They included polyps removed endoscopically and polyps found incidentally in resected stomachs with gastric ulcers and cancer. The hyperplastic polyps were essentially composed of cystic foveolae and pyloric type glands, lined by cells identical to those of the normal gastric mucosa. Thirty one pol

11. Loss of Apc heterozygosity and abnormal tissue building in nascent intestinal polyps in mice carrying a truncated Apc gene.
Mutations in the APC (adenomatous polyposis coli) gene appear to be responsible for not only familial adenomatous polyposis but also many sporadic cases of gastrointestinal cancers. Using homologous recombination in mouse embryonic stem cells, we constructed mice that contained a mutant gene encoding a product truncated at a 716 (Apc delta 716). Mendelian tr
