1. Diagnosis of acute graft-versus-host disease in the gastrointestinal tract of patients undergoing allogeneic hematopoietic stem cell transplantation. A descriptive and critical study of diagnostic tests
ABSTRACT Introduction: Acute graft-versus-host disease (GVHD) is one of the major causes of morbidity and mortality in patients undergoing allogeneic hematopoietic stem cell transplantation (AHSCT) and has become the subject of several studies to understand and treat it. Objective: This study does a descriptive analysis of the apoptotic index (AI) evaluati

2. Prevalência de doença celíaca em pacientes dispépticos sem diarreia atendidos na Disciplina de Gastroenterologia e Endoscopia Digestiva do Hospital Universitário Pedro Ernesto da UERJ / Prevalence of celiac disease in dyspeptic patients without diarrhea referred to the Gastroenterology Division at Pedro Ernesto University Hospital in Rio de Janeiro
A Doença Celíaca (DC) é uma doença autoimune que afeta o intestino delgado de indivíduos geneticamente susceptíveis após contato com o glúten. Diversos estudos têm relatado aumento da prevalência ao longo dos anos. Objetivo: Determinar a prevalência de DC em pacientes adultos sem diarreia encaminhados à Disciplina de Gastroenterologia do HUPE da

3. Biodistribuição do pertecnetato de sódio (Na99mTcO4) em ratos submetidos à ressecção extensa de intestino delgado
Massive resection of the small intestine results in short bowel syndrome with anti-absorptive effect and repercussions on the metabolism. Morphologic and functional evaluation may be necessary in order to control wrapped organs. Scintigraphy an examination with little invading and no biologic damage can be used. The purpose were to assess the biodistribution

4. Glycoconjugate expression in normal, metaplastic, and neoplastic human upper gastrointestinal mucosa.
Glycoconjugate structure in upper gastrointestinal epithelium was studied using five lectins to determine the relationship between aberrant differentiation and glycoconjugate expression. Specimens of normal esophagus, stomach, and duodenum were examined and compared with specimens of columnar metaplasia in the esophagus (Barrett's esophagus) and specimens of

5. Villous tumors of the duodenum.
Nineteen cases of villous tumors of the duodenum are reported. They have a predilection for the ampullary region, tend to present with obstructive jaundice, especially if malignancy is present, and have a high prevalence of cancer (12 of 19, or 63%). Even when biopsies are available, the diagnosis of cancer is frequently missed (5 of 9 proven cancers, 56% fa

6. Induction and Distribution of Intestinal Immune Responses after Administration of Recombinant Cholera Toxin B Subunit in the Ileal Pouches of Colectomized Patients
The induction and dissemination of mucosal immune responses to recombinant cholera toxin B subunit (rCTB) administered into the ileal pouches of patients, who had been colectomized because of ulcerative colitis, was analyzed. Biopsies from the duodenum and ileal pouch were collected, along with peripheral blood and ileostomy fluids. Two immunizations induced

7. Nature of the inflammatory cell infiltrate in duodenitis.
Counts of lamina propria and intraepithelial cells, lymphoid and polymorphonuclear, have been performed on semithin sections of endoscopic biopsies from the duodenum of patients with ulcer-associated duodenitis, with non-specific duodenitis, and from controls. In both types of duodenitis there were significant increases in lamina propria counts of plasma cel

8. Biopsy specimen appearances of ischaemic gastritis in splanchnic arterial insufficiency.
A 74 year old man presented with a one month history of epigastric discomfort, anorexia, weight loss, and postprandial vomiting. The diagnosis of ischaemia was made on endoscopic biopsies from the stomach and duodenum. He was too ill for major vascular surgery and died eight days after admission. Postmortem examination confirmed the diagnosis of splanchnic a

9. Technique for microdissection and measurement in biopsies of human small intestine.
A microdissection and measurement technique has been adapted for biopsy of human small intestine. Specimens fixed in alcohol and acetic acid are Schiff stained in bulk. Villi and crypts are then dissected out under a dissecting microscope, placed under a coverslip, examined, measured, and the number of mitoses in individual crypts counted. With this method s

10. Localization of Persistent Enterocytozoon bieneusi Infection in Normal Rhesus Macaques (Macaca mulatta) to the Hepatobiliary Tree
Enterocytozoon bieneusi is the most common microsporidian parasite recognized in human patients with AIDS. Recently, we identified a virtually identical organism causing a spontaneous infection associated with hepatobiliary and intestinal disease in simian immunodeficiency virus (SIV)-infected macaques. To examine the natural history of the infection, we exa

11. Ribotyping of Helicobacter pylori from clinical specimens.
Ribotyping is a method used to type strains of bacteria by analyzing the restriction enzyme digestion patterns of the rRNA genes. This method was applied to 126 strains of Helicobacter pylori from 100 unrelated symptomatic patients who had endoscopies done and to 15 strains from 15 infected subjects from seven families. Analysis of the rRNA gene patterns rev

12. ΔF508 CFTR protein expression in tissues from patients with cystic fibrosis
Heterologous expression of the cystic fibrosis transmembrane conductance regulator (CFTR) provided evidence that the major cystic fibrosis (CF) mutation ΔF508 leads to defective protein folding in the endoplasmic reticulum, which prevents its processing and targeting to the cell surface. In this study, we investigated endogenous CFTR expression in skin biop
