Community-acquired pneumonia by Chlamydophila pneumoniae: a clinical and incidence study in Brazil.

As there was not any data on Chlamydia pneumoniae (TWAR) infections in Brazil so far, a prospective cohort study of adult patients hospitalized due to CAP was carried out for one year in a Brazilian university general hospital to detect the incidence of CAP by Chlamydophila pneumoniae (TWAR) for one year. During a whole year 645 consecutive patients hospitalized due to an initial presumptive diagnosis of respiratory diseases by ICD-10 (J00-J99), excluding upper respiratory diseases, were screened; 59 consecutive patients with CAP were diagnosed. They had determinations of serum antibodies to C.

Community-acquired pneumonia by Legionella pneumophila serogroups 1-6 in Brazil.

A prospective cohort study of adult patients hospitalized due to community-acquired pneumonia was carried out for 1 year in a Brazilian university general hospital to detect the incidence of community-acquired pneumonia by Legionella pneumophila serogroups 1-6. During a whole year, a total of 645 consecutive patients who were hospitalized due to a initial presumptive diagnosis of respiratory disease by ICD-10 (J00-J99), excluding upper respiratory diseases, were screened to detect the patients with community-acquired pneumonia. Fifty-nine consecutive patients hospitalized due to community-acquired pneumonia between July 19, 2000 and July 18, 2001, were included in the study.

Transjugular liver biopsy: histological diagnosis success comparing the trucut to the modified aspiration Ross needle.

Background: Transjugular liver biopsy is an alternative procedure for patients who present contraindications to standard percutaneous procedure.

Aim: To compare the rate of histological diagnosis obtained on transjugular liver biopsy with an automated trucut needle and with a modified Ross needle. PATIENTS / METHOD: Eighty-five patients with suspicion of chronic liver diseases and presenting contraindications for percutaneous liver biopsy (coagulopathy, massive ascites, morbid obesity, or chronic renal problems) were submitted to 89 transjugular liver biopsies between March 1994 and April 2001 at "Hospital São José, Irmandade da Santa Casa de Misercórdia", Porto Alegre, RS, Brazil.

[Experience in patients with suspected chronic liver disease and contraindication for percutaneous biopsy using modified Ross needle].

Purpose: This work aimed at introducing the transjugular liver biopsy technique oriented by radiologic methods in our hospitals. This technique is indicated for obtaining histopathologic diagnosis in patients clinically and laboratory suspected of having chronic liver disease with contraindications to percutaneous liver biopsy.

Methods: Liver biopsy was obtained with a modified Ross needle through the right jugular vein and right hepatic vein under fluoroscopic control.

Efficacy of computed axial tomography in the evaluation of the involvement of the respiratory tract in patients with squamous cell carcinoma of esophagus.

Squamous cell carcinoma of the esophagus is endemic in Rio Grande do Sul, the most southern state of Brazil, where the incidence reaches 27 out of 100,000 inhabitants per year. Palliative treatments, surgical or nonsurgical, impose lower mortality and lower costs. The choice of the best treatment for each patient depends on the neoplasia staging, and the local involvement of the tracheobronchial tree by tumor characterizes incurability.
