Abstract PDF PT PDF EN Portuguese Text

Objective: To develop and validate a Portuguese-language version of the Asthma Control Test (ACT) for use in Brazil. Methods: The study comprised 290 asthma outpatients over 12 years of age. The patients completed the ACT questionnaire and had an appointment with a pulmonologist in order to assess asthma control in two visits. In the first visit, the patients also underwent spirometry. The second visit took place at least four weeks later. Results: We found that a cut-off score of 18 points-to differentiate between subjects with controlled asthma and those with uncontrolled asthma-had a sensitivity of 93%, a specificity of 74%, a negative predictive value of 86% and a positive predictive value of 85%. The positive and negative likelihood ratios were 3.58 and 0.09, respectively. The questionnaire has an outstanding capacity to differentiate uncontrolled asthma from controlled asthma, with an area under the ROC curve of 0.904. The patients whose symptoms remained stable between the two visits had similar scores, demonstrating good test-retest reproducibility, with an intraclass correlation coefficient of 0.93. The patients whose symptoms improved in the second visit had significantly higher scores, demonstrating good responsiveness of the questionnaire in the identification of changes in disease control. Conclusions: The Portuguese-language version of the ACT showed good test-retest reproducibility and was capable of discriminating the levels of asthma control and detecting changes in asthma control in a population of patients with a low level of education and low family income at a public health facility in Brazil.

Abstract PDF PT PDF EN Portuguese Text

Objective: To analyze the clinicopathological aspects of bronchioloalveolar carcinoma (BAC) and the survival in a sample of patients at clinical stage I. Methods: A retrospective study involving 26 patients diagnosed with clinical stage I BAC and undergoing surgery at the Thoracic Diseases Institute of the Federal University of Rio de Janeiro, in the city of Rio de Janeiro, Brazil, between 1987 and 2007. We analyzed clinicopathological and radiological aspects, as well as mortality and survival. The data, which were collected from the medical charts of the patients, were statistically analyzed. Results: Females predominated (n = 16). The mean age at diagnosis was 68.5 years. Most patients were active smokers (69.2%). The most common forms of presentation of BAC were the asymptomatic form (84.6%) and the nodular form (88.5%). Involvement of the upper lobes predominated (57.7%). Stage IB was the most common pathological stage, followed by stages IA and IIB (46.2%, 38.4% and 15.4%, respectively). There was no in-hospital mortality. Four patients died during the postoperative follow-up, with a mean disease-free survival time of 21.3 months. The overall five-year survival rate was 83%. The probability of survival for the patients diagnosed after 1999 showed a trend toward an increase when compared with that for those diagnosed up through 1999 (three-year survival rate: 92% vs. 68%; p = 0.07). Conclusions: The clinicopathological aspects of this study sample were similar to those of patients with BAC evaluated in previous studies.

J Bras Pneumol.2010;36(2):175-180

Abstract PDF PT PDF EN Portuguese Text

Objective: To determine the main congenital lung malformations treated and the principal diagnostic methods employed, as well as the indications for surgical treatment and the results obtained, at a referral facility for pediatric thoracic surgery. Methods: We reviewed the medical charts of 52 patients anatomopathologically diagnosed with congenital lung malformations and who had been submitted to pulmonary resection between January of 1997 and December of 2006. Exclusion criteria were age ≥ 12 years and incomplete clinical data. The final sample comprised 35 patients. Results: In this sample, the mean age was 31 months, and there was a predominance of males (n = 21). The anatomopathological findings were cystic adenomatoid malformation (n = 14), congenital lobar emphysema (n = 13), pulmonary sequestration (n = 8) and arteriovenous malformation (n = 1). The most common type of lung resection was left lower lobectomy (in 25.71%) followed by different types of segmentectomy (in 22.85%), left upper lobectomy (in 22.85%), right upper lobectomy (in 14.28%), right lower lobectomy (in 8.57%) and middle lobectomy (in 5.71%). Of the 35 patients, 34 (97.14%) were submitted to closed pleural drainage, with a mean duration of thoracic drainage of 3.9 days. Ten patients (28.5%) presented with postoperative complications. There were no deaths in our sample. Conclusions: Pulmonary resection for the treatment of congenital lung malformations is a safe procedure, presenting low morbidity and no mortality at a referral facility for pediatric thoracic surgery.

5 - Short-term effect of tiotropium in COPD patients being treated with a β2 agonist

Efeito de curto prazo do tiotrópio nos portadores de DPOC em tratamento com β2-agonista

Frederico Leon Arrabal Fernandes, Vanessa Aparecida Leão Pavezi, Sérvulo Azevedo Dias Jr., Regina Maria Carvalho Pinto, Rafael Stelmach, Alberto Cukier

J Bras Pneumol.2010;36(2):181-189

Abstract PDF PT PDF EN Portuguese Text

Objective: To evaluate the short-term impact of tiotropium in patients with severe or very severe COPD who complain of dyspnea despite being currently treated with other bronchodilators. Methods: A prospective study including patients with severe or very severe COPD and complaining of dyspnea at rest or on minimal exertion. Every 15 days, the bronchodilator treatment regimen was altered, from salmeterol to tiotropium to salmeterol+tiotropium. At the end of each regimen, pulmonary function tests and the six-minute walk test (6MWT) were performed. The degree of dyspnea and the ability to perform activities of daily living were also assessed. To evaluate patient ability to perform activities of daily living, we employed the London Chest Activity of Daily Living (LCADL), validated for use in Brazil. Results: We evaluated 52 patients, 30 of whom completed the study. The use of tiotropium in isolation resulted in significant improvement in dyspnea at baseline (mean Medical Research Council scale score reduced from 3.0 to 2.5) and at the end of 6MWT (mean Borg scale score reduced from 6.1 to 4.5), and the differences were significant (p < 0.05 for both). The use of the salmeterol+tiotropium combination resulted in a significant (81 mL) increase in FEV1 and a 5.7 point improvement in the LCADL score. Conclusions: The introduction of tiotropium into the treatment of patients with severe or very severe COPD and using long-acting β2 agonists improves pulmonary function and provides symptomatic relief, as perceived by patients in the short term. These results, obtained under real life treatment conditions, support the use of the salmeterol+tiotropium combination in specific treatment protocols for these patients.

J Bras Pneumol.2010;36(2):190-196

Abstract PDF PT PDF EN Portuguese Text

Objective: To evaluate the competence of senior medical students in diagnosing tuberculosis (TB) based on their reading of chest X-rays, as well as to identify the factors associated with high scores for the overall interpretation of chest X-rays. Methods: In October 2008, a convenience sample of senior medical students who had undergone formal training in radiology at the Federal University of Rio de Janeiro School of Medicine, in the city of Rio de Janeiro, Brazil, were invited to participate in the study. Six chest X-rays (three of TB patients and three of patients without TB) were selected. Participants were asked to choose one of the three probable radiological interpretations, and one of the four subsequent suitable clinical approaches. They also completed a questionnaire designed to collect data related to demographics, career of interest, time spent in emergency rooms and year of study. The sensitivity and specificity related to competence in the radiological diagnosis of TB, as well as a score for the overall interpretation of chest X-rays, were calculated. Results: The sensitivity of the probable radiological diagnosis of pulmonary TB, based on the three chest X-rays of patients with TB (minimal, moderate and extensive) was 86.5%, 90.4% and 94.2%, respectively, and the specificity was 90%, 82% and 42%. The only factor associated with a high score for the overall radiological interpretation was the year of study. Conclusions: In this sample of medical students, who had received formal training in radiology early in their medical school course, the competence in interpreting the chest X-rays of TB patients was good. The year of study seems to influence overall chest X-ray reading skill.

J Bras Pneumol.2010;36(2):197-204

Abstract PDF PT PDF EN Portuguese Text

Objective: To evaluate breathing pattern and thoracoabdominal motion during breathing exercises. Methods: Twenty-four patients with class II or III obesity (18 women; 6 men) were studied on the second postoperative day after gastroplasty. The mean age was 37 ± 11 years, and the mean BMI was 44 ± 3 kg/m2. Diaphragmatic breathing, incentive spirometry with a flow-oriented device and incentive spirometry with a volume-oriented device were performed in random order. Respiratory inductive plethysmography was used in order to measure respiratory variables and thoracoabdominal motion. Results: Comparisons among the three exercises showed significant differences: tidal volume was higher during incentive spirometry (with the flow-oriented device or with the volume-oriented device) than during diaphragmatic breathing; the respiratory rate was lower during incentive spirometry with the volume-oriented device than during incentive spirometry with the flow-oriented device; and minute ventilation was higher during incentive spirometry (with the flow-oriented device or with the volume-oriented device) than during diaphragmatic breathing. Rib cage motion did not vary during breathing exercises, although there was an increase in thoracoabdominal asynchrony, especially during incentive spirometry with the flow-oriented device. Conclusions: Among the breathing exercises evaluated, incentive spirometry with the volume-oriented device provided the best results, because it allowed slower, deeper inhalation.

Abstract PDF PT PDF EN Portuguese Text

Objective: Physiologically, VC can vary according to gender, age, body weight and posture, as well as ethnic and anthropometric characteristics. In addition, various diseases can alter VC. In order to measure VC, it is necessary to motivate the patient, to make the instructions understandable, to provide clear information and to have a capable examiner. The objective of this study was to determine the impact that positive reinforcement during spirometry has on the measurement of VC in healthy volunteers. Methods: A randomized clinical trial involving 105 healthy volunteers, randomly allocated to one of two groups: control and intervention. In both groups, VC was assessed as baseline (VC1) and again 15 days later (VC2). Positive reinforcement was provided only to patients in the intervention group and only during the determination of VC2. Results: There were no significant differences between the groups regarding the baseline characteristics. Females predominated in both groups. There was an increase in VC2 in both groups (p < 0.01), and VC2 was higher in the intervention group than in the control group (p < 0.01). Conclusions: These findings demonstrate the importance of using the behavioral strategy in combination with traditional practice in order to obtain better results. The use of positive reinforcement during the determination of VC has proven to be an effective, simple and easily applied strategy.

Abstract PDF PT PDF EN Portuguese Text

Objective: To determine the prevalence of respiratory symptoms and smoking, as well as pulmonary function parameters among charcoal production workers in three cities in southern Brazil. Methods: This was an observational study including 67 individuals. Data were obtained by means of interviews and spirometry. Results: Of the 67 workers, 50 (75.0%) were male; mean age, 46.52 ± 13.25 years; mean BMI, 25.7 ± 3.85 kg/m2; FEV1, 3.24 ± 0.82 L (93.2 ± 16.0% of predicted); FVC, 4.02 ± 0.92 L (95.5 ± 14.3% of predicted); and FEV1/FVC, 80.31 ± 9.82. The most common upper airway symptoms were sneezing and nasal secretion-in 24 workers (35.82%)-whereas the most common lower airway symptom was cough-in 15 (22.38%). Of the 67 workers, 21 (31.34%) were smokers. In comparison with the nonsmokers, the smokers more often presented with cough (OR = 5.00; p = 0.01), nasal obstruction (OR = 3.50; p = 0.03), nasal itching (OR = 8.80; p = 0.01) and wheezing (OR = 10.0; p = 0.03), as well as presenting with lower FEV1 values (2.93 ± 0.80 vs. 3.38 ± 0.80 L; p = 0.04). We detected occupational rhinitis in 14 workers (20.85%), asthma in 4 (5.97%) and COPD in 4 (5.97%). Conclusions: Respiratory symptoms and airflow reduction were more common in the smoking workers. Controlling the progression of the pyrolysis did not increase the prevalence of respiratory symptoms in the charcoal production workers studied.

Abstract PDF PT PDF EN Portuguese Text

Objective: To identify characteristics related to smoking in hospitalized patients and to assess the knowledge that such patients have regarding the relationship between nicotine dependence and smoking-related diseases. Methods: The study included 186 patients (males, 59%; mean age, 51.3 ± 16.8 years) who were evaluated regarding demographic characteristics, diagnosis at admission, smoking history and passive smoke exposure. All of the patients completed a questionnaire regarding their knowledge of the relationship between smoking and disease. Results: Of the 186 patients, 42 (22.6%) were smokers, 64 (34.4%) were former smokers and 80 (43%) stated they were never smokers; 136 (73%) reported passive smoke exposure. In the sample as a whole, 21.5% of the patients were diagnosed with a smoking-related disease at admission, compared with 39% of those who were smokers or former smokers. The proportion of individuals who were unaware of the relationship between smoking and the cause of hospitalization was similar among current smokers and former smokers (56% and 65%, respectively). Only 19% of the current smokers believed that smoking might have affected their health, compared with 32% of the former smokers (p = 0.22). The proportion of individuals who believed that quitting smoking depends on willpower was significantly higher among former smokers and never smokers than among current smokers (64% and 53%, respectively, vs. 24%; p < 0.001 and p = 0.008). Although 96% of the patients believed that smoking causes dependence, only 60% identified smoking as a disease. Conclusions: This study shows the disconnect between the recognition of smoking as a cause of dependence and the recognition of smoking as a disease, as well as the general lack of awareness that former and current smoking constitute a risk factor for the development and progression of disease.

Abstract PDF PT PDF EN Portuguese Text

Objective: To determine the drug resistance profile of Mycobacterium tuberculosis in the state of Mato Grosso do Sul, Brazil, between 2000 and 2006. Methods: Descriptive study of reported tuberculosis cases in the Brazilian Case Registry Database. We included only those cases in which M. tuberculosis culture was positive and sensitivity to drugs (rifampicin, isoniazid, streptomycin and ethambutol) was tested. Löwenstein-Jensen and Ogawa-Kudoh solid media were used for cultures, as was an automated liquid medium system. Sensitivity tests were based on the proportion method. Results: Among the 783 cases evaluated, males predominated (69.7%), as did patients in the 20-49 year age bracket (70%), a diagnosis of pulmonary tuberculosis (94.4%) and positive HIV serology (8.6%); 645 (82.4%) were new cases, and 138 (17.6%) had previously been treated. Resistance to at least one drug was found in 143 cases (18.3%). The primary resistance (PR) rate was, respectively, 8.1%, 1.6%, 2.8% and 12.4%, for monoresistance, multidrug resistance (MDR), other patterns of resistance and resistance to at least one drug, whereas the acquired resistance (AR) rate was 14.5%, 20.3%, 10.9% and 45.7%, respectively, and the combined resistance (CR) rate was 9.2%, 4.9%, 4.2% and 18.3%, respectively. In PR, streptomycin was the most common drug, whereas isoniazid was the most common in AR and CR (7.2% and 3.7%, respectively). Conclusions: These high levels of resistance undermine the efforts for tuberculosis control in Mato Grosso do Sul. Acquired MDR was 12.7 times more common than was primary MDR, demonstrating that the previous use of drug therapy is an indicator of resistance. These levels reflect the poor quality of the health care provided to these patients, showing the importance of using the directly observed treatment, short course strategy, as well as the need to perform cultures and sensitivity tests for the early diagnosis of drug resistance.

Abstract PDF PT PDF EN Portuguese Text

Objective: To determine the principal adverse effects of the tuberculosis treatment regimen recommended by the Brazilian Ministry of Health. Methods: A prospective descriptive study involving 79 tuberculosis patients treated at the Clinical Research Center of the Cassiano Antonio Moraes University Hospital, in the city of Vitória, Brazil, between 2003 and 2006. The treatment regimen consisted of isoniazid, rifampicin, pyrazinamide and ethambutol for four months, followed by rifampicin and isoniazid for two months. During the treatment period, the patients were clinically evaluated every week and had a monthly medical visit. Results: The overall incidence of adverse effects was 83.54%. Articular/bone/muscle involvement was the most common, followed by skin involvement (24.94% and 22.09%, respectively). Adverse effects were more common in the second month of treatment (41.59%). Modification of the treatment regimen was unnecessary. One patient required concomitant medication to counter the adverse effects. The cure rate was 100%. Conclusions: The overall incidence of adverse effects related to the new treatment regimen recommended by the Brazilian Ministry of Health was high. However, none of those effects demanded a change in the regimen, which was effective in the patients evaluated.

Atitudes dos pneumologistas brasileiros em face da dependência de nicotina: inquérito nacional

Carlos Alberto de Assis Viegas, Antonio Gabriel Teles Valentim, Jaene Andrade Pacheco Amoras, Euler Junior Moreira Nascimento

J Bras Pneumol.2010;36(2):239-242

Abstract PDF PT PDF EN Portuguese Text

Smoking is a medical condition, since there is drug dependence, and health professionals should treat it as a chronic disease. In order to understand the attitudes of Brazilian pulmonologists toward smokers, we conducted a national survey, using a questionnaire posted on the Internet, of 2,800 pulmonologists, 587 (21%) of whom completed and returned the questionnaires. We found that 3.2% of the respondents did not believe that smoking is a medical condition. Only 14.7% treated smokers, and 32.4% stated that they would refer smokers to another professional for treatment. These results suggest that Brazilian pulmonologists have insufficient knowledge of smoking cessation therapies.

Tuberculose em pacientes com artrite reumatoide: a dificuldade no diagnóstico da forma latente

Daniela Graner Schuwartz Tannus Silva, Bruna Daniella de Souza Silva, Ana Paula Junqueira-Kipnis, Marcelo Fouad Rabahi

J Bras Pneumol.2010;36(2):243-251

Abstract PDF PT PDF EN Portuguese Text

Since the beginning of the use of anti-TNF in the treatment of rheumatoid arthritis and other inflammatory diseases, cases of pulmonary tuberculosis and extrapulmonary tuberculosis have been reported in patients receiving such treatment. In most cases, the disease develops by the time the patient has received the sixth infusion. Every patient should be evaluated for latent tuberculosis infection prior to the use of a TNF inhibitor. However, the diagnosis of latent tuberculosis infection is a challenge. The tuberculin test, which was the only test available to detect latent tuberculosis infection for nearly a century, presents a number of limitations. Tests based on the detection of the in-vitro production of IFN-γ by mononuclear cells activated by specific antigens appear to be more accurate and have been studied in patients with rheumatoid arthritis.

15 - The educational component in an integrated approach to bronchial asthma

El componente educativo en el abordaje integral del asma bronquial

María Paola Fasciglione, Claudia Elena Castañeiras

J Bras Pneumol.2010;36(2):252-259

Abstract PDF PT PDF EN Portuguese Text

Bronchial asthma is an inflammatory chronic disease of the respiratory tract whose prevalence is increasing worldwide. Since there is no curative treatment available, the principal objective of every approach is to control the disease and to improve the quality of life of patients. Over the last few decades, intervention programs supplementing conventional medical treatments have been tested and implemented. The majority of such programs consist of educational interventions or include some type of educational component. In this study, we attempted to determine the characteristics and the impact of educational interventions on asthma by means of the following: a) an updated review of the various educational interventions developed and implemented for asthma patients; b) the identification of aspects that are common to all of these interventions; and c) the analysis of the findings in the literature regarding the impact that these interventions have on the health and quality of life of patients. We conclude that educational interventions are effective in improving the health and quality of life of asthma patients, as well as in reducing the use and costs of health resources. These findings indicate the importance of including an educational component as part of an integrated approach to this population. Likewise, the inherent complexity of the educational process highlights the importance of a complementary joint effort including various health professionals.

16 - Usefulness of chest CT in the diagnosis of pulmonary sequestration

A utilidade da TC de tórax no diagnóstico do sequestro pulmonar

José Gustavo Pugliese, Thiago Prudente Bártholo, Heron Teixeira Andrade dos Santos, Eduardo Haruo Saito, Cláudia Henrique da Costa, Rogério Rufino

J Bras Pneumol.2010;36(2):260-264

Abstract PDF PT PDF EN Portuguese Text

Pulmonary sequestration is a rare congenital anomaly, characterized by nonfunctional embryonic pulmonary tissue. Pulmonary sequestration accounts for 0.15-6.40% of all congenital pulmonary malformations. This anomaly, which is classified as intralobar or extralobar, involves the lung parenchyma and its vascularization. We report the case of a 56-year-old male presenting with hemoptysis. A chest X-ray showed an area of opacity behind the cardiac silhouette in the base of the left hemithorax. Chest CT scans with intravenous contrast revealed pulmonary sequestration. The patient underwent surgery, in which the anomalous tissue was successful resected. The postoperative evolution was favorable, and the patient was discharged to outpatient treatment.

Abstract PDF PT PDF EN Portuguese Text

Despite preventive measures, lung hyperinflation is a relatively common complication following single lung transplantation to treat pulmonary emphysema. The progressive compression of the graft can cause mediastinal shift and respiratory failure. In addition to therapeutic strategies such as independent ventilation, the treatment consists of the reduction of native lung volume by means of lobectomy or lung volume reduction surgery. We report two cases of native lung hyperinflation after single lung transplantation. Both cases were treated by means of lobectomy or lung volume reduction surgery.
