Objectives: To determine the effect that the treatment of GERD has on the clinical management, as well as the respiratory function, of patients with asthma and to evaluate the clinical characteristics of this group of patients. Methods: Patients with asthma and concomitant GERD, documented using 24 h pH-metry, were evaluated by means of quality of life questionnaires, as well as questionnaires related to respiratory and digestive symptoms. In addition, esophageal manometry, spirometry and the determination of peak expiratory flow were also performed prior to and after the study. Forty-nine individuals who were diagnosed with GERD by means of 24 h esophageal pH-metry were selected and participated in a clinical randomized double-blind placebo-controlled study, involving the administration of 40 mg/day of pantoprazol for 12 consecutive weeks. Results: Forty-four individuals completed the study (n = 22 per group). There was significant improvement in the scores for respiratory symptoms and quality of life only in the group that received pantoprazol (p = 0.01 and p = 0.001, respectively). No respiratory function parameters changed in either group. Conclusions: In this study, the effective treatment of GERD improved patient quality of life, and the symptoms of asthma significantly decreased in the group that received the medication. There were no changes in pulmonary function parameters.

Abstract PDF PT PDF EN Portuguese Text

Objective: To determine the accuracy of the variables related to the fixed-height stair climbing test (SCT) using maximal oxygen uptake (VO2 max) as the gold standard. Methods: The SCT was performed on a staircase consisting of 6 flights (72 steps; 12.16 m total height), with verbal encouragement, in 51 patients. Stair-climbing 'time' was measured, and the variables 'work' and 'power' also being calculated. The VO2 max was measured using ergospirometry according to the Balke protocol. We calculated the Pearson linear correlation (r), as well as the values of p, between the SCT variables and VO2 max. To determine accuracy, the VO2 max cut-off point was set at 25 mL/kg/min, and individuals were classified as normal or altered. The cut-off points for the SCT variables were determined using the receiver operating characteristic curve. The Kappa statistic (k) was used in order to assess concordance. Results: The following values were obtained for the variable 'time': cut-off point = 40 s; x_ = 41 ± 15.5 s; r = −0.707; p < 0.005; specificity = 89%; sensibility = 83%; accuracy = 86%; and k = 0.724. For 'power', the values obtained were as follows: cut-off point = 200 w; x_ = 222.3 ± 95.2 w; r = 0.515; p < 0.005; specificity = 67%; sensibility = 75%; accuracy = 71%; and k = 0.414. Since the correlation between 'work' and VO2 max was not significant, that variable was discarded. Conclusion: Of the SCT variables tested, using VO2 max as the gold standard, the variable 'time' was the most accurate.

J Bras Pneumol.2007;33(2):134-140

Abstract PDF PT PDF EN Portuguese Text

Objective: To create a reference map of mediastinal lymph nodes through the analysis of their size, number and distribution in various lymph node stations. Method: A total of 50 cadavers, 38 males and 12 females, were studied. Of those 50, 39 were Caucasian. The mean age was 59.9 ± 14.1 years, the mean height was 173.1 ± 7.6 cm, and the mean weight was 71.0 ± 12.0 kg. A bilateral mediastinal dissection was performed in order to resect and isolate all lymph nodes. The area, as well as the major and minor transverse diameters, of each lymph node was determined by radiographic imaging analysis. Results: In a sample of 485 chains, 1742 lymph nodes were dissected (2.58 ± 1.89 lymph nodes/station), revealing a mean number of 21.2 ± 8.5 lymph nodes on the right and 13.6 ± 6.3 on the left. The lymph node stations 1, 2R, 4R, 5, and 7 were present in more than 90% of the sample. Only the 4R and 7 lymph node stations were always present. The lymph node stations 2L, 3p, and 8 were present in 32, 36, and 54% of the sample, respectively. Mediastinal lymph nodes were present in greater numbers in the 2R, 4R and 7 lymph node stations. In addition, these stations presented the largest mediastinal lymph nodes. Conclusion: Composing a reference map for lymph node sizes was feasible. No alterations were observed in the distribution, number, or size of lymph nodes in the age brackets studied, regardless of gender, race, weight, or height.

Abstract PDF PT PDF EN Portuguese Text

Objective: To compare the resistance of manual suture with that of mechanical suture immediately after the suture of the left bronchial stump of dogs submitted to pneumonectomy. Methods: A total of 15 mixed-breed dogs of both genders, each weighing between 8 and 23 kg, were randomly divided into 2 groups. In group I (n = 7), the bronchial stump was sutured manually (the Sweet method) and, in group II (n = 8), it was stapled. Immediately after the closure of the bronchial stump, the intratracheal pressure was progressively increased in a controlled manner. Results: The mean rupture pressure of the bronchial stump suture line was 33.71 mmHg in group I and 89.87 mmHg in group II (p < 0.01). Conclusion: These data allowed us to conclude that mechanical suture of the bronchial stump, submitted to pressure immediately after closure, is more resistant than is manual suture in dogs submitted to pneumonectomy.

Objective: To determine the efficacy of using forced expiratory volume in six seconds (FEV6) as a surrogate for forced vital capacity (FVC) in the diagnostic screening for chronic obstructive pulmonary disease (COPD) by comparing FEV1/FVC ratios with FEV1/FEV6 ratios. Methods: In November of 2003, on World COPD Day, we conducted a campaign of diagnostic screening for COPD. The participants completed the clinical questionnaire of the Global Initiative for Obstructive Lung Disease, and those who responded affirmatively to at least three questions underwent spirometry. Results: A total of 134 individuals responded to three questions affirmatively and underwent spirometry. Of those, 59 were excluded: 45 for being non-smokers and 14 due to the fact that their tests did not meet the American Thoracic Society criteria for satisfactory spirometry. The number of tests in which the FEV1/FEV6 ratio was below 70% was similar to that found for the FEV1/FVC ratio. The sensitivity of FEV1/FEV6 in diagnosing airway obstruction (defined as FEV1/FVC below 70%) was 92%, and its specificity was 99%. The positive predictive value was 100%, and the negative predictive value was 98%. The Kendall correlation test revealed r = 0.99 (p < 0.0001). The t-test for paired samples revealed a negative correlation: t = −5.93 (p < 0.0001). Conclusion: The FEV1/FEV6 proved efficient for use in the diagnostic screening for COPD. There is a strong correlation between FEV1/FVC and FEV1/FEV6.

9 - Effect of theophylline associated with short-acting or long-acting inhaled β2-agonists in patients with stable chronic obstructive pulmonary disease: a systematic review

Efeito da teofilina associada ao β2-agonista inalatório de curta ou longa duração, em pacientes com doença pulmonar obstrutiva crônica estável: revisão sistemática

Eliane Cristina Zacarias, Aldemar Araújo Castro, Sônia Cendon

J Bras Pneumol.2007;33(2):152-160

Abstract PDF PT PDF EN Portuguese Text

Objectives: To determine whether, in stable patients with chronic obstructive pulmonary disease, administration of theophylline in combination with short-acting or long-acting inhaled β2-agonists is more efficacious than is a placebo or each of these drugs used in isolation. Methods: A systematic review and meta-analysis were carried out. All randomized and double-blind clinical trials found in the literature were selected. Results: A total of eight studies were included. In comparing the effect of theophylline combined with β2-agonists to that of a placebo, we found a statistically significant improvement in mean FEV1 (0.27 L; 95%CI: 0.11 to 0.43) and mean dyspnea (-0.78; 95%CI: -1.26 to -0.29). None of the meta-analyses performed detected any difference between the results obtained using theophylline combined with β2-agonists and those obtained using β2-agonists alone. When the administration of theophylline combined with β2-agonists was compared to that of theophylline alone, there was a statistically significant improvement in mean dyspnea (-0.19; 95%CI: -0.34 to 0.04). Conclusion: In patients with stable chronic obstructive pulmonary disease, theophylline combined with β2 agonists is more efficacious than is a placebo in terms of improving FEV1 and dyspnea. In addition, theophylline combined with β2 agonists is more efficacious than is theophylline in improving dyspnea. Furthermore, administration of theophylline combined with β2 agonists is no more efficacious, for any of the variables studied, than is the use of β2-agonists in isolation.

Abstract PDF PT PDF EN Portuguese Text

Objective: To evaluate the health-related quality of life of patients with chronic obstructive pulmonary disease receiving long-term oxygen therapy (LTOT) at home through oxygen cylinders and compare these results with those obtained six months after the transition from oxygen cylinders to oxygen concentrators. Methods: A total of 45 patients were evaluated. Of those, 24 had chronic hypoxemia and 21 presented no evidence of hypoxemia. The patients with chronic hypoxemia had been regularly receiving LTOT for at least the last six months and were evaluated at baseline, while using cylinders, and six months after the transition from cylinders to concentrators. The non-hypoxemic patients were evaluated at the same time points as were the hypoxemic patients. In order to evaluate quality of life, a version of the Saint George's Respiratory Questionnaire (SGRQ), translated and validated for use in Brazil, was administered. Results: At baseline, quality of life, as evaluated using the total score and the symptom and impact domain scores of the SGRQ, was more impaired in the hypoxemic patients than in the non-hypoxemic patients. After six months of using the concentrators, the hypoxemic patients presented a significant improvement in the quality of life, and, at that time, no difference was found between the patients with and without hypoxemia. Conclusion: Our findings show that quality of life is impaired in patients with chronic obstructive pulmonary disease and chronic hypoxemia, that their quality of life can be improved through regular use of LTOT, and that the oxygen delivery system has an influence on this improvement.

Abstract PDF PT PDF EN Portuguese Text

Objective: To analyze the shuttle walk test, and its respective retest, comparing children with cystic fibrosis (CF) to normal children. Methods: The children were divided into two groups: the CF group, composed of children in whom the diagnosis had been confirmed through sweat testing; and the control group, composed of normal children with no history of pulmonary diseases and no alterations in respiratory function. The children were submitted to at least two consecutive tests, 30 min apart. We evaluated distance walked, cardiac overload, peripheral oxygen saturation (SpO2) and subjective perception of exertion (dyspnea at rest scale and Borg dyspnea scale). Results: A total of 28 children were evaluated. Ages ranged from 7 to 15 years (11.57 ± 2.50 and 11.28 ± 1.85 years for the CF and control groups, respectively). The Borg scale scores were significantly higher in the controls (p = 0.007). No differences were found regarding cardiac overload and SpO2. In relation to the intergroup retest, the controls presented significant improvements on the second test, both in the distance walked and in dyspnea at rest (p = 0.014 and p = 0.036, respectively). The CF group presented a significant improvement only in the dyspnea at rest score (p = 0.168 and p = 0.042, respectively). Conclusion: The cardiac overload imposed by the test did not differ between the groups. The greater fatigue at the beginning of the second test suggests that the 30 min rest between the tests was insufficient.

Abstract PDF PT PDF EN Portuguese Text

Objective: To evaluate the impact that the implementation of therapeutic guidelines has on the empirical treatment of nosocomial pneumonia. Methods: A clinical trial, using historical controls and involving current ICU patients who had acquired nosocomial pneumonia, was carried out from June of 2002 to June of 2003. All were treated according to therapeutic guidelines developed by the Commission for Nosocomial Infection Control of the institution (group with intervention). As controls, the medical charts of the patients who acquired nosocomial pneumonia between June of 2000 and June of 2001 (group without intervention) were analyzed. Mortality and mean treatment period, as well as the length of hospital and ICU stays, were determined for the patients who acquired nosocomial pneumonia. Results: Mortality associated with pneumonia was lower in the group treated according to the therapeutic guidelines (26 vs. 53.6%; p = 0.00). As for overall mortality, there was no statistically significant difference between the two periods (51 vs. 57.9%; p = 0.37). There was also no difference in the type of microorganisms isolated, treatment period, length of hospital stay or length of ICU stay. Conclusion: The implementation of therapeutic guidelines for the treatment of nosocomial pneumonia acquired in the ICU can be efficacious in decreasing mortality rates.

Objective: To determine the levels of the tumor markers carcinoembryonic antigen (CEA), cytokeratin 19 fragment (CYFRA21-1) and carbohydrate antigen 15-3 (CA 15-3) in the blood and pleural fluid of patients with benign or malignant pleural effusion, evaluating the sensitivity of each marker in these fluids. Methods: We prospectively evaluated 85 patients with pleural effusion. The study of the pleural fluid observed the criteria established in the literature. Levels of the markers were determined using electrochemiluminescence. The sensitivity was determined on the condition that the specificity was ≥ 90%. Results: Of the 85 cases, 36 (42.4%) were malignant, 30 (35.3%) were benign, and the results were inconclusive in 19 (22.3%). In the malignant cases, the CEA and CYFRA21-1 levels were higher in the pleural fluid than in the blood, which was not observed for CA 15-3. In the benign cases, the CYFRA21-1 levels were higher in the pleural fluid than in the blood, whereas the opposite was found for CEA and CA 15-3. There were significant differences between malignant and benign cases for all markers, in pleural fluid and blood. In the pleural fluid, the sensitivity of CEA, CYFRA21-1 and CA 15-3 was 69.4, 69.4 and 66.7%, respectively, and the combined sensitivity was 80.6%. In the blood, the sensitivity was 57.1%, 71.4% and 48.6% for CEA, CYFRA21-1 and CA 15-3, respectively, and the combined sensitivity was 77%. Conclusion: The results suggest that these markers might be useful in the differentiation between malignant and benign pleural effusion.

Abstract PDF PT PDF EN Portuguese Text

Objective: To describe treatment outcomes (cure, noncompliance or death) after the implementation of the Directly Observed Treatment, Short-course (DOTS) strategy for tuberculosis control in the city of São José do Rio Preto, Brazil, between 1998 and 2003. Methods: A descriptive study, based on secondary data (National Case Registry database, Tuberculosis Epidemiology database, and the 'Black Book' Registry), was conducted using a specific instrument. The data were analyzed using descriptive statistics. Results: After the implementation of the DOTS strategy, there was a decrease in noncompliance and case detection rates as well as an increase in cure and death rates. The increase in the number of tuberculosis-related deaths might be attributable to three factors: the predominance of the disease in individuals over 50 years of age, tuberculosis/HIV co-infection, and the presence of accompanying diseases. Conclusion: The implementation of the DOTS strategy strengthened the decentralization of the tuberculosis control plans as well as the integration of the Basic Health Care Clinic teams with the Tuberculosis Control Program team. Political commitment of the administrator to tuberculosis control, in conjunction with the policy of benefits and incentives, is essential for the sustainability of the DOTS strategy.

Abstract PDF PT PDF EN Portuguese Text

Objective: To present epidemiological data on patients diagnosed with tuberculosis, as well as on associated factors, and to determine the efficacy of the National Tuberculosis Control Program in Bagé, Brazil. Methods: A retrospective study was carried out at the Pablo Barcellos Center, analyzing cases of tuberculosis reported from January 2001 to December 2004. Data were collected through the review of clinical charts and from the National Case Registry database. Results: During this period, of the 4468 sputum smear microscopies performed, 131 were positive, with higher prevalence among males aged 26 to 35 years old. Prevalence was lower among those aged 65 and above. Over 50% of the patients were Caucasian, had only 1 to 3 years of schooling and worked in low-income jobs (mean salary, 265 Brazilian reals/month). There was no significant difference between smokers and former smokers/nonsmokers, and only one of the 131 cases was HIV positive. Conclusion: The number of sputum smear microscopies performed in Bagé increased in the past four years. In 2003 and 2004, it exceeded the goal of the National Tuberculosis Control Program. However, the number of new cases decreased, demonstrating the efficacy of the active search for tuberculosis cases in the city.

16 - Transfusion-related acute lung injury

Lesão pulmonar aguda associada à transfusão

Antonio Fabron Junior, Larissa Barbosa Lopes, José Orlando Bordin

J Bras Pneumol.2007;33(2):206-212

Abstract PDF PT PDF EN Portuguese Text

Transfusion-related acute lung injury (TRALI) is a serious clinical syndrome associated with the transfusion of plasma-containing blood components. Recently, TRALI has come to be recognized as the leading cause of transfusion-related death in the United States and United Kingdom. This complication typically presents as shortness of breath, hypoxemia, hypotension, fever and noncardiogeneic pulmonary edema, all occurring during or within 6 h after transfusion. Although the mechanism of TRALI has not been fully elucidated, it has been associated with human leukocyte antigen antibodies (class I, class II or neutrophil alloantigens) and with biologically active mediators in stored cellular blood components. Most of the donors implicated in cases of TRALI are multiparous women. Rarely diagnosed, TRALI can be confused with other causes of acute respiratory failure. Greater knowledge regarding TRALI on the part of clinicians could be crucial in preventing and treating this severe complication of blood transfusion.

17 - Diabetes mellitus in patients with cystic fibrosis

Diabetes melito: uma importante co-morbidade da fibrose cística

Crésio de Aragão Dantas Alves, Renata Arruti Aguiar, Ana Cláudia S Alves, Maria Angélica Santana

J Bras Pneumol.2007;33(2):213-221

Abstract PDF PT PDF EN Portuguese Text

Cystic fibrosis-related diabetes (CFRD) is the principal extra-pulmonary complication of cystic fibrosis, occurring in 15-30% of adult cystic fibrosis patients. The number of cystic fibrosis patients who develop diabetes is increasing in parallel with increases in life expectancy. The aim of this study was to review the physiopathology, clinical presentation, diagnosis and treatment of CFRD. A bibliographic search of the Medline and Latin American and Caribbean Health Sciences Literature databases was made. Articles were selected from among those published in the last twenty years. Insulin deficiency, caused by reduced β-cell mass, is the main etiologic mechanism, although insulin resistance also plays a role. Presenting features of type 1 and type 2 diabetes, CFRD typically affects individuals of approximately 20 years of age. It can also be accompanied by fasting, non-fasting or intermittent hyperglycemia. Glucose intolerance is associated with worsening of nutritional status, increased morbidity, decreased survival and reduced pulmonary function. Microvascular complications are always present, although macrovascular complications are rarely seen. An oral glucose tolerance test is recommended annually for patients ≥ 10 years of age and for any patients presenting unexplained weight loss or symptoms of diabetes. Patients hospitalized with severe diseases should also be screened. If fasting hyperglycemia persists for more than 48 h, insulin therapy is recommended. Insulin administration remains the treatment of choice for diabetes and fasting hyperglycemia. Calories should not be restricted, and patients with CFRD should be managed by a multidisciplinary team.

J Bras Pneumol.2007;33(2):222-225

Abstract PDF PT PDF EN Portuguese Text

A 27-year-old male patient presented with respiratory symptoms, bilateral enlargement of the cervical lymph nodes and enlarged liver. In the imaging studies, bilateral enlargement of the hilar nodes was observed, together with pulmonary infiltrate. The patient was submitted to lung and liver biopsies, which revealed noncaseating granulomas. The clinical, radiological and histopathological findings were consistent with sarcoidosis and lymph node amyloidosis. The combination of sarcoidosis and amyloidosis has rarely been reported.

J Bras Pneumol.2007;33(2):226-228

Abstract PDF PT PDF EN Portuguese Text

Castleman disease is a rare disorder generally characterized by a mediastinal nodule, with a great variety of alternative presentations regarding age, clinical manifestations and evolution. This case report describes a 40-year-old female patient presenting with uncharacteristic chest pain for a few years. A chest X-ray revealed a hypotransparency on the right side. Computed tomography and pulmonary arteriography did not elucidate the diagnosis, which was made through surgical resection and anatomopathological examination of the nodule, which presented characteristics of angiofollicular hyperplasia, or Castleman disease. This article emphasizes the importance of adding this disease to the list of morbidities in the differential diagnosis of pulmonary solitary nodules.

Abstract PDF PT PDF EN Portuguese Text

Lymphangiomatosis, a rare diseases of controversial origin, occurs in individuals of any age, regardless of gender, but is predominantly seen in younger individuals. It often presents with thoracic involvement, although, the bones, spleen and liver can also be affected. Histologically, the pulmonar involvement includes proliferation, complex anastomoses and secondary dilatation of the lymphatic vessels. Clinically, the presentation is variable. Although radiographic findings can be suggestive of the disease, the final diagnosis is made histologically. We report two cases of lymphangiomatosis, both in females: one was oligosymptomatic and is being treated for the disease; the other had a more progressive form, was diagnosed quite late and ultimately died of the disease.
