OBJECTIVE To describe spirometric reference equations for healthy Brazilian adults who have never smoked and to compare the predicted values with those derived in 1992. METHODS Reference equations for spirometry were derived in 270 men and 373 women living in eight cities in Brazil. Ages ranged from 20 to 85 years in women and from 26 to 86 years in men.(More)
BACKGROUND In hypersensitivity pneumonitis (HP), survival can be predicted on the basis of the severity of fibrosis in surgical lung biopsy, but few data are available on the influence of clinical, functional, tomographic and histologic findings on prognosis. OBJECTIVES To describe the impact on survival of clinical data, histological patterns, and HRCT(More)
BACKGROUND Pulmonary gas exchange impairment (GEI) is a common consequence of intrathoracic sarcoidosis presenting with important therapeutic and prognostic implications. OBJECTIVE To determine the role of clinical, radiographic and functional variables in predicting GEI during moderate exercise at the estimated lactate threshold (theta(L)) in patients(More)
OBJECTIVE To compare the most recent (2006) predicted values of forced vital capacity and forced expiratory volume in one second for spirometry in Brazilians with those obtained using other reference equations and to validate the findings through comparisons with a new sample of normal Brazilians. METHODS Forced spirometry was performed, in accordance(More)
Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia with airflow obstruction is a rare form of lung injury. All of the reported cases have been diagnosed by surgical lung biopsy. Only three of the reported cases presented with diffuse interstitial lung opacities on HRCT scans. We report three additional cases of this entity. All of the patients(More)
Serum levels of interferon-gamma (IFN-γ) were evaluated inCalomys callosus, and Swiss mice during the course of infection by four strains ofTrypanosoma cruzi. All strains stimulated the production of this interleukine; however, the timing of its onset and permanence When chronically infected animals with no detectable serum IFN-γ were challenged with the(More)
Objective: this prospective study aimed to assess the quality of life related to health (QLRH) of patients with lung cancer after chemotherapy treatment. Method: The QLRH was assessed using the questionnaires Quality-of-Life Questionnaire-Core 30 (QLQ-C30) and Lung Cancer Module (LC13), version 3.0. Results: the sample was made up of 11 women and 19 men,(More)
OBJECTIVE To determine the frequency of and the factors related to delayed diagnosis of sarcoidosis in Brazil. METHODS We evaluated patients with a biopsy-proven diagnosis of sarcoidosis, using a questionnaire that addressed the following: time since symptom onset and since the first medical visit; and the number and specialty of the physicians visited.(More)
BACKGROUND Sarcoidosis is a multisystem granulomatous disease of unknown origin that can cause sudden death. OBJECTIVE Electrophysiological evaluation of patients with suspected sarcoidosis with cardiac involvement. METHODS We studied 22 patients with mean age of 55.32 ± 13.13 years, diagnosed with sarcoidosis and suspected cardiac involvement. These(More)
AIM To assess the interference of nail polish on the reading of peripheral oxygen saturation in patients with chronic obstructive pulmonary disease on the step exercise. METHODS In this study, there was the inclusion of patients with chronic obstructive pulmonary disease, current non-smokers, of both sexes. Four different colours of nail polish were used(More)
