Objective: To profile the characteristics of adult patients with bronchiectasis, drawing comparisons between cystic fibrosis (CF) patients and those with bronchiectasis from other causes in order to determine whether it is rational to extrapolate the bronchiectasis treatment given to CF patients to those with bronchiectasis from other causes. Methods: A retrospective analysis of the medical charts of 87 patients diagnosed with bronchiectasis and under follow-up treatment at our outpatient clinic. Patients who had tuberculosis (current or previous) were excluded. We evaluated the clinical, functional, and treatment data of the patients. Results: Of the 87 patients with bronchiectasis, 38 (43.7%) had been diagnosed with CF, through determination of sweat sodium and chloride concentrations or through genetic analysis, whereas the disease was due to another etiology in 49 (56.3%), of whom 34 (39.0%) had been diagnosed with idiopathic bronchiectasis. The mean age at diagnosis was lower in the patients with CF than in those without (14.2 vs. 24.2 years; p < 0.05). The prevalence of symptoms (cough, expectoration, hemoptysis, and wheezing) was similar between the groups. Colonization by Pseudomonas aeruginosa or Staphylococcus aureus was more common in the CF patients (82.4 vs. 29.7% and 64.7 vs. 5.4%, respectively). Conclusions: The causes and clinical manifestations of bronchiectasis are heterogeneous, and it is important to identify the differences. It is crucial that these differences be recognized so that new strategies for the management of patients with bronchiectasis can be developed.

Objective: To evaluate physical performance on the six-minute walk test (6MWT) in patients with non-cystic fibrosis bronchiectasis and to investigate its relationship with quality of life (QoL). To identify predictors of exercise performance, we also investigated whether six-minute walk distance (6MWD) is associated with clinical and spirometric findings. Methods: This was a cross-sectional study involving patients with non-cystic fibrosis bronchiectasis (age,  18 years), with at least one respiratory symptom for  2 years and an FEV1  70% of predicted. Patients underwent clinical evaluation, pulmonary function tests, the 6MWT, and QoL assessment with the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). Results: We included 70 patients (48 females). Mean age was 54.5 ± 17.7 years, and mean FEV1 was 44.9 ± 14.5% of predicted. The patients were divided into two groups: 6MWD-low (6MWD below the predicted lower limit; n = 23); and 6MWD-norm (normal 6MWD; n = 47). The following variables were significantly lower in the 6MWD-low group than in the 6MWD-norm group: age; age at diagnosis of bronchiectasis; proportion of former smokers; body mass index (BMI); FEV1% of predicted; and MEP% of predicted. There were no significant differences in the SF-36 scores between the groups. In the logistic regression model, lower age and lower BMI were significantly associated with lower 6MWD. Conclusions: In this sample, there was a high proportion of patients who had a lower than expected 6MWD. Although 6MWD was not related to QoL, it was associated with age and BMI.

Background: Bronchiectasis is a frequently found disease in medical practice in Brazil leading to significant morbidity and decrease in quality of life of the affected individuals. Objectives: To study diagnostic and therapeutic aspects in a series of hospitalized patients with bronchiectasis in a department of pulmonary diseases. Methods: Signs, symptoms, microbiological and radiographic data, and therapeutic results were studied in 170 hospitalized patients between 1978 and 2001 - females 62.4%, males 37.6%, and aged from 12 to 88 years (mean age 36.8 yrs). Previous history of pneumonia in childhood was detected in 52.5% of the patients, tuberculosis in 19.8%; 8.8% had bronchial asthma, and 2 had Kartagener's syndrome. Results: The most common symptoms were cough (100.0%), expectoration (96.0%) and pulmonary rales (66.0%). The pulmonary lesions were unilateral in 46.5% of the cases. Pneumococcus, H. influenzae or mixed flora were found in 85.0% of the examined sputa. All 170 patients received antibiotics and postural drainage, and 88 of them (younger and with a higher functional reserve) were also submitted to pulmonary resections (82 unilateral and 6 bilateral). Two deaths occurred, and repetitive hospitalizations were more frequent among the clinically treated patients. The follow up showed that most of the surgically treated patients had significant symptoms improvement and rarely needed to be re-hospitalized. Conclusions: In the majority of the patients, lung resection surgery improved permanently the prolonged bronchopulmonary symptoms of patients with bronchiectasis, differently from the patients who received only clinical treatment.

Objective: To analyze and compare the transport properties of respiratory secretions, classified by selected parameters, in individuals with bronchiectasis unrelated to cystic fibrosis. Methods: We collected mucus samples from 35 individuals with bronchiectasis unrelated to cystic fibrosis. The samples were first classified by their surface properties (adhesive or nonadhesive), as well as by their aspect (mucoid or purulent). We then tested the samples regarding relative transport velocity (RTV), displacement in a simulated cough machine (SCM), and contact angle (CA). For the proposed comparisons, we used ANOVA models, with a level of significance set at 5%. Results: In comparison with nonadhesive samples, adhesive samples showed significantly less displacement in the SCM, as well as a significantly higher CA (6.52 ± 1.88 cm vs. 8.93 ± 2.81 cm and 27.08 ± 6.13° vs. 22.53 ± 5.92°, respectively; p < 0.05 for both). The same was true in the comparison between purulent and mucoid samples (7.57 ± 0.22 cm vs. 9.04 ± 2.48 cm and 25.61 ± 6.12° vs. 21.71 ± 5.89°; p < 0.05 for both). There were no significant differences in RTV among the groups of samples, although the values were low regardless of the surface properties (adhesive: 0.81 ± 0.20; nonadhesive: 0.68 ± 0.24) or the aspect (purulent: 0.74 ± 0.22; mucoid: 0.82 ± 0.22). Conclusions: The respiratory secretions of patients with bronchiectasis showed decreased mucociliary transport. Increased adhesiveness and purulence cause the worsening of transport properties, as demonstrated by the lesser displacement in the SCM and the higher CA.

A pneumonia por Pneumocystis carinii (PPC), que é a infecção oportunista que mais comumente põe em risco a vida de pacientes com síndrome da imunodeficiência adquirida (SIDA), tem sido há bastante tempo associada a outros estados de imunodeficiência. Os relatos iniciais sugeriram que a apresentação clínica da PPC em SIDA difere de sua apresentação em outras situações, embora ambas tenham sofrido modificações nos últimos anos. O objetivo do presente estudo é comparar os achados clínicos e laboratoriais da PPC em SIDA com os de pacientes portadores de PPC sem SIDA. Foram revisados os prontuários médicos de todos os pacientes em nossa instituição que tiveram o diagnóstico confirmado de PPC e SIDA durante o ano de 1994 (17 pacientes) e sem SIDA no período de 1992-1994 (dez pacientes). Quando da apresentação, os pacientes sem SIDA tinham uma duração de sintomas significativamente menor (8,4 ± 7,7 vs 19,5 ± 10,2 dias, p < 0,05), menor PaO2 média a ar ambiente (47 ± 8,2 vs 63 ± 10mmHg, p < 0,05), e mais freqüente infiltrado unilateral no radiograma do tórax (60 vs 6%, p < 0,05). O índice de mortalidade da PPC foi marcadamente maior nos pacientes sem SIDA (40 vs 6%, p < 0,05), e este fato estava associado com retarde no início do tratamento específico nestes pacientes. Devido a seu curso mais agudo, apresentação radiológica atípica e alto índice de mortalidade, concluímos que o diagnóstico de PPC deve ser afastado em pacientes que recebem terapia imunossupressora e que profilaxia anti-PPC deve ser fortemente considerada em pacientes que serão imunossuprimidos.

Objetivo: Realizar a tradução para a língua portuguesa e a adaptação cultural para uso no Brasil do Quality of Communication Questionnaire (QOC) para pacientes com DPOC em cuidados paliativos. Métodos: Após a aprovação do autor do questionário e do comitê de ética da instituição, a versão original do QOC com 13 itens foi traduzida, de forma independente, por dois tradutores brasileiros com fluência na língua inglesa. Uma síntese das duas traduções foi realizada por uma médica bilíngue e os dois tradutores, que chegaram a um consenso, gerando uma versão na língua portuguesa. Essa versão foi retraduzida por dois tradutores nativos de países de língua inglesa com fluência na língua portuguesa. Para resolver quaisquer discrepâncias, um comitê de especialistas comparou a versão original com todas as versões produzidas e, assim, obteve-se a versão pré-final do QOC. O pré-teste foi aplicado em 32 pacientes internados em UTIs de três hospitais públicos da grande Florianópolis (SC) para avaliar a clareza e a aceitabilidade cultural da versão pré-final do QOC. Resultados: A média de idade dos pacientes foi de 48,5 ± 18,8 anos. A maioria dos itens foi bem compreendida e aceita, recebendo pontuações ≥ 8. Um item, sobre morte, suscitou dificuldades na compreensão dos participantes do pré-teste. Ao submeter a retradução ao autor do QOC, ele solicitou alterações em dois itens, que foram acatadas. Após essas alterações, a versão final foi aprovada. Conclusões: A tradução e a adaptação cultural do QOC para uso no Brasil foi concluída com sucesso.
