BACKGROUND Pancreatic involvement in AIDS is rarely mentioned in medical literature. AIMS To identify the main morphological patterns of the pancreas using optical and electron microscopy in AIDS patients. DESIGN An open, prospective, and sequential study in a tertiary institutional hospital. METHODS Consecutive post-mortems of 109 AIDS patients and(More)
BACKGROUNDS Dyspepsia is a condition that affects 25% of the U.S. population, and, when associated with pyrosis, its prevalence reaches 40%. Patients with chronic renal insufficiency not only present higher circulating levels of gastrin and gastric dysmotilty, but also make use of a great amount of drugs for the treatment of their comorbidities. This(More)
BACKGROUNDS The aim of this study is identify the main morphological patterns of the pancreas in AIDS patients in use of Higly Active Antiretorviral Therapy (HAART). METHODS We conducted a cross sectional study in the year of 2010. The inclusion criteria were patients older than 18 years who died of AIDS with the use of HAART (2006-2009) and underwent to(More)
INTRODUCTION Frequent histologic changes (90%) in the pancreas suggesting protein-energy malnutrition were found in a previous necropsy study of pancreas morphology in patients with AIDS. However, additional studies were required to clarify subcellular changes. AIM To ultrastructurally analyze pancreas changes in AIDS patients through transmission(More)
In HIV-seropositive individuals, the incidence of acute pancreatitis may achieve 40% per year, higher than the 2% found in the general population. Since 1996, when combined antiretroviral therapy, known as HAART (highly active antiretroviral therapy), was introduced, a broad spectrum of harmful factors to the pancreas, such as opportunistic infections and(More)
OBJECTIVES To determine the efficacy of a simple, short-term and low-cost eradication treatment for Helicobacter pylori (H. pylori) using omeprazole, tetracycline, and furazolidone in a Brazilian peptic ulcer population, divided into 2 subgroups: untreated and previously treated for the infection. PATIENTS AND METHODS Patients with peptic ulcer disease(More)
Hepatitis B is responsible for the development of half of hepatocellular carcinoma cases and is a major cause of hepatic insufficiency. The vaccine against hepatitis B virus does not exhibit the same high efficacy in patients on hemodialysis as it does in immunocompetent individuals. The medical literature recommends vaccination with four doses (40 mg each)(More)
The involvement of the gastrointestinal tract in the co-infection of HIV and Leishmania is rarely reported. We report the case of an HIV-infected adult man co-infected with a disseminated form of leishmaniasis involving the liver, lymph nodes, spleen and, as a feature reported for the first time in the English literature, the pancreas. Light microscopy(More)
OBJECTIVES Infection caused by Helicobacter pylori (H. pylori) is one of the most common causes of chronic infection in the world. The presence of the infection is strongly associated with the neoplasia of the gastrointestinal tract, and its diagnosis is easily made by means of invasive or non-invasive methods. Among such methods, the H. pylori antigen(More)
PURPOSE To determine the eradication rate of an ultra-short treatment schedule for Helicobacter pylori infection in a population with peptic ulcers, using omeprazole, secnidazole, and azithromycin in a once-daily dose for 3 days. METHODS Thirty patients with peptic ulcer diagnosed by upper endoscopy and for Helicobacter pylori infection by rapid urease(More)
