Emanuel Sarinho, Gladys Reis e Silva de Queiroz, Maria Laura Campelo de Melo Dias, Alexandre Jorge Queiroz e Silva

J Bras Pneumol.2007;33(4):365-371

Abstract PDF PT PDF EN Portuguese Text

Objective: To determine whether the children and adolescents with acute asthma attacks admitted to two public hospitals in the city of Recife, Brazil underwent outpatient follow-up treatment for the prevention and control of asthma. Methods: A prospective case series study of hospitalized patients with asthma. The patients were asked to complete a questionnaire at admission in order to determine the frequency of prophylactic outpatient follow-up treatment. Patients presenting two or more attacks of asthma that were responsive to bronchodilators were classified as having asthma. Results: In the intervals between asthma attacks, 67% (112/167 - data regarding 2 patients were not available) of the patients had been treated only in the emergency room. Although 53.3%(89/167 - data regarding 2 patients were not provided) of the patients had been referred to outpatient treatment, only 16% (27/169) had visited an outpatient asthma clinic regularly for preventive treatment, and only 13% (22/169) had used prophylactic medication. Conclusion: Most of the children and adolescents hospitalized with asthma had not undergone preventive outpatient follow-up treatment. Various problems related to the health care system, such as non-referral for outpatient follow-up treatment at hospital discharge, limited access to outpatient clinics, and the cost of prophylactic medication, might have contributed to the low rate of outpatient follow-up treatment in the population studied. Public health care policies that allow asthma control programs to work effectively should be implemented.

5 - Causes of death in asthma patients enrolled in the Bahia State Program for the Control of Asthma and Allergic Rhinitis

Causas de óbitos entre asmáticos graves admitidos no Programa de Controle da Asma e da Rinite Alérgica na Bahia

Adelmir Souza-Machado, Carolina Souza-Machado, Daisy Freitas Silva, Eduardo Vieira Ponte, Alvaro A. Cruz

J Bras Pneumol.2007;33(4):372-379

Abstract PDF PT PDF EN Portuguese Text

Objective: To report demographic and clinical characteristics of patients with asthma who evolved to death, as well as to describe the conditions related to this outcome in a subgroup of patients admitted to the Program for the Control of Asthma and Rhinitis in Bahia (ProAR). Methods: A descriptive, retrospective, observational study. Data from clinical charts and death certificates of 16 patients of 930 subjects with severe asthma monitored at the ProAR Central Reference Center from December 2003 to June 2006 were reviewed. Results: Of the 930 patients participating in the program, 16 (1.72%) died. Of these, there were 10 males and 6 females, ranging in age from 39 to 74 years (median, 55 years); 12 (75%) of the patients were black. Time since diagnosis ranged from 1 to 68 years (median, 30 years). In 43.8 and 53.8%, respectively, there was a personal or family history of atopy. Ex-smokers (<10 pack-years) accounted for 37.5% of the cases. Causes of death listed on the death certificates were as follows: asthma or asthma exacerbations in 8 (50%); respiratory failure in 3 (18.75%); acute heart infarction in 2 (12.5%); hepatitis in 1 (6.25%); hypovolemic shock in 1 (6.25%); and cardiorespiratory arrest in 1 (6.25%). Of the 16 deaths, 13 (81.25%) occurred inside hospitals. Conclusion: Asphyxia and cardiovascular diseases were the most common atributed causes of mortality in this subgroup of patients with severe asthma. Hospital-based mortality, male gender, advanced age, long-term disease and fixed airflow obstruction were the aspects most frequently observed in the cases studied.

J Bras Pneumol.2007;33(4):380-388

Abstract PDF PT PDF EN Portuguese Text

Objective: To describe the prevalence of signs and symptoms of respiratory disease among pig farmers in Braço do Norte, Santa Catarina, Brazil, evaluating the characteristics of swine confinement buildings and identifying potential risk factors. Methods: An exploratory, cross-sectional, observational study involving interviews and pulmonary function tests (spirometry). Aspects related to job history, work conditions, and environment, as well as to respiratory status and smoking, were evaluated. Odds ratios were used to estimate the chances of exposure when comparing pig farmers according to the signs and symptoms of respiratory disease. Results: The prevalence of clinical signs and symptoms of respiratory disease was 84.3%, clinical manifestations of bronchial asthma were detected in 5.6% of the farmers evaluated, and chronic bronchitis was diagnosed in 5.1% of the workers over the age of 40. Only 2.6% used specific individual respiratory protection devices. Respiratory disease was positively associated with low socioeconomic level, low level of education, smoking, the use of wood stoves, and the use of disinfectants. Work load and length of employment were both apparently associated with a lower prevalence of respiratory disease. Conclusion: The association between duration of employment and lower prevalence of respiratory disease can be attributed to the healthy worker effect. However, the evident respiratory impairment among pig farmers and the limited use of personal protective equipment draw attention to the need to implement a program to monitor exposure and regulate environmental factors.

7 - Inspiratory capacity, exercise limitation, markers of severity, and prognostic factors in chronic obstructive pulmonary disease

Capacidade inspiratória, limitação ao exercício, e preditores de gravidade e prognóstico, em doença pulmonar obstrutiva crônica

Clarice Guimarães de Freitas, Carlos Alberto de Castro Pereira, Carlos Alberto de Assis Viegas

J Bras Pneumol.2007;33(4):389-396

Abstract PDF PT PDF EN Portuguese Text

Objective: To correlate the postbronchodilator (post-BD) inspiratory capacity (IC), % of predicted, with other markers of severity and prognostic factors in chronic obstructive pulmonary disease (COPD). Methods: Eighty stable patients with COPD performed forced vital capacity and slow vital capacity maneuvers, as well as the 6-min walk test, prior to and after receiving albuterol spray (400 μg). Patients were divided into four groups, based on post-BD forced expiratory volume in one second. Several variables were tested to establish correlations with the post-BD distance walked, using univariate and multivariate analysis. Post-BD IC was found to correlated with Global Initiative for Chronic Obstructive Lung Disease (GOLD) staging and with the Body mass index, airway Obstruction, Dyspnea, and Exercise capacity (BODE) index. Results: Multivariate regression analysis revealed that the distance walked, % predicted, correlated significantly with the IC post-BD, % predicted (p = 0.001), long-term oxygen use (p = 0.014), and number of medications used in the treatment (p = 0.044). IC ≤ 70% was observed in 56% patients in GOLD stages 3 or 4 vs. 20% in GOLD 1 or 2 (p < 0.001). IC ≤ 70% was observed in (60%) patients with BODE score 3 or 4 vs. (33%) BODE score 1 or 2 (p = 0.02). Conclusion: Post-BD IC% predicted is the best functional predictor of distance walked and is significantly associated with GOLD staging and BODE index. Therefore, We propose that the inspiratory capacity should be added to the routine evaluation of the COPD patients.

8 - New reference values for forced spirometry in white adults in Brazil

Novos valores de referência para espirometria forçada em brasileiros adultos de raça branca

Carlos Alberto de Castro Pereira, Taeko Sato, Sílvia Carla Rodrigues

J Bras Pneumol.2007;33(4):397-406

Abstract PDF PT PDF EN Portuguese Text

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. Spirometry examinations followed the recommendations of the Brazilian Thoracic Society. Lower limits were derived by the analysis of the fifth percentiles of the residuals. Results: Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC and FEV1/forced expiratory volume in six seconds (FEV6) were best fitted by linear regression. Flows were best fitted using log equations. For both genders, greater height resulted in lower values for FEV1/FVC, FEV1/FEV6 and flow/FVC ratios. The reference values for FEV1 and FVC in the present study were higher than those derived for Brazilian adults in 1992. Conclusion: New predicted values for forced spirometry were obtained in a sample of white Brazilians. The values are greater than those obtained in 1992, probably due to technical factors.

J Bras Pneumol.2007;33(4):407-413

Abstract PDF PT PDF EN Portuguese Text

Objective: To assess, using ultrasound, the effects that changes in body position have on diaphragmatic mobility in healthy subjects during spontaneous breathing. Methods: The study involved seven healthy female volunteers, all of whom were nonsmokers, well nourished, and free of any cardiopulmonary disease. They were submitted to pulmonary function testing and ultrasound evaluation of the mobility of the right diaphragm by the craniocaudal displacement of the left branch of the portal vein using an ultrasound device in mode B. The mobility of the right diaphragm was evaluated in right decubitus and in left decubitus. The order of evaluation was previously determined in a random drawing. Results: The average mobility of the right diaphragm in right decubitus (51.30 ± 9.69 mm) was significantly higher (p = 0.03) than that observed in left decubitus (45.93 ± 10.37 mm). Conclusion: The results suggest that, during spontaneous ventilation, the dependent portion of the diaphragm presents greater mobility than does the nondependent portion, and that the technique used was sufficiently sensitive to detect variations in diaphragmatic mobility related to changes in posture.

Abstract PDF PT PDF EN Portuguese Text

To evaluate the applicability of the 12-Item Short-Form Health Survey (SF-12) as an instrument to measure health-related quality of life in a sample of patients with progressive systemic sclerosis (PSS) through the analysis of its reproducibility and its correlation with functional and clinical parameters. Methods: A test-retest reproducibility study for the comparative analysis of the intraclass correlation coefficients (ICCs) of the SF-12 and the SF-36. A total of 46 patients diagnosed with PSS were studied, regardless of the presence of respiratory symptoms. Results: The physical component summary 12 (PCS-12) score had an ICC of 0.47 (95%CI: 0.05-0.71; p < 0.02), whereas the mental component summary (MCS-12) score had an ICC of 0.72 (95%CI: 0.49-0.84; p < 0.001). The PCS-36 score had an ICC of 0.88 (95%CI: 0.78-0.93; p < 0.001), and the MCS-36 score also had an ICC of 0.88 (95%CI: 0.78-0.93; p < 0.001). Conclusion: The SF-12 is a reliable instrument for measuring health-related quality of life in patients with PSS, since it has been proven to be reproducible. However, this version of the SF-12 should only be used in clinical research settings.

J Bras Pneumol.2007;33(4):423-428

Abstract PDF PT PDF EN Portuguese Text

Objective: To compare the American-European Consensus Conference (AECC) definition of acute respiratory distress syndrome (ARDS) to autopsy findings. Methods: All patients who died in the intensive care unit of the Federal University of Juiz de Fora University Hospital between 1995 and 2003 and were submitted to autopsy were included in the study. Patient clinical charts were reviewed to establish whether cases met the AECC criteria for a diagnosis of ARDS, histologically defined as the presence of diffuse alveolar damage (DAD). Results: During the study period, 592 patients died, and 22 were submitted to autopsy. Of those 22 patients, 10 (45%) met the AECC criteria, and 7 (32%) met the histopathological criteria for DAD. The AECC clinical criteria presented a sensitivity of 71% (95%CI: 36-92%) and a specificity of 67% (95%CI: 42-85%). The positive and negative predictive values were, respectively, 50 and 83%, whereas the positive and negative likelihood ratios were, respectively, 2.33 and 0.47. The histopathological findings in the 5 patients who met AECC criteria but did not present DAD were pneumonia (n = 2), pulmonary embolism (n = 1), tuberculosis (n = 1), and cryptococcosis (n = 1). Conclusion: The accuracy of the AECC definition of ARDS was godless than satisfactory. Due to the low positive predictive value and the low positive likelihood ratio, other hypotheses must be considered when ARDS is suspected.

Abstract PDF PT PDF EN Portuguese Text

Objective: To describe the differences in the clinical and radiological presentation of tuberculosis in the presence or absence of HIV infection. Methods: A sample of 231 consecutive adults with active pulmonary tuberculosis admitted to a tuberculosis hospital were studied, assessing HIV infection, AIDS, and associated factors, as well as re-evaluating chest X-rays. Results: There were 113 HIV-positive patients (49%) Comparing the 113 HIV-positive patients (49%) to the 118 HIV-negative patients (51%), the former presented a higher frequency of atypical pulmonary tuberculosis (pulmonary lesions accompanied by intrathoracic lymph node enlargement), hematogenous tuberculosis, and pulmonary tuberculosis accompanied by superficial lymph node enlargement, as well as presenting less pulmonary cavitation. The same was found when HIV-positive patients with AIDS were compared to those without AIDS. There were no differences between the HIV-positive patients without AIDS and the HIV-negative patients. Median CD4 counts were lower in HIV-positive patients with intrathoracic lymph node enlargement and pulmonary lesions than in the HIV-positive patients with pulmonary lesions only (47 vs. 266 cells/mm3; p < 0.0001), in HIV-positive patients with AIDS than in those without AIDS (136 vs. 398 cells/mm3; p < 0.0001) and in patients with atypical pulmonary tuberculosis than in those with other forms of tuberculosis (31 vs. 258 cells/mm3; p < 0.01). Conclusion: Atypical forms and disseminated disease predominate among patients with advanced immunosuppression. In regions where TB prevalence is high, the presence of atypical pulmonary tuberculosis or pulmonary tuberculosis accompanied by superficial lymph node enlargement should be considered an AIDS-defining condition.

J Bras Pneumol.2007;33(4):437-442

Abstract PDF PT PDF EN Portuguese Text

Objective: To develop a system for the molecular diagnosis of tuberculosis by polymerase chain reaction (PCR), constructing primers based on the difference in gene organization of the intergenic region of phospholipase C (plcB-plcC region), which differentiates Mycobacterium tuberculosis from other mycobacteria. Methods: A PCR product of the expected size (432 bp) was obtained from M. tuberculosis and M. africanum only. A total of 33 mycobacterial isolates and 273 clinical samples from patients suspected of having tuberculosis were examined. These were used in the comparative study of the PCR technique versus culture. Results: For PCR versus culture, the data showed 93.8% accuracy (p < 0.0001), 93.1% sensitivity (CI: 88.7-96.0), and 96.4% specificity (CI: 96.1-99.4). The Kappa value (0.82) shows that there was a near-perfect concordance between the two tests. Conclusion: The use of the plcB-plcC region in PCR amplification was found to be an important and reliable tool for the specific diagnosis of tuberculosis in the samples analyzed.

Abstract PDF PT PDF EN Portuguese Text

To describe some aspects of tuberculosis in a low-income community (the Complexo de Manguinhos, in Rio de Janeiro, Brazil), a retrospective study was carried out. Of the 290 cases reported in the 2000-2002 period, 75.8% were new cases. The annual incidence rates were 157/100,000 (2000), 205/100,000 (2001), and 145/100,000 (2002). Although there was a tendency toward a decrease in the number of cases over the period studied, the difference was not significant, suggesting that tuberculosis continues to be endemic in the area. Therefore, despite the existence of local public health care services, more efficient strategies should be implemented in order to increase the effectiveness of tuberculosis control programs in the area.

15 - Technical modification of unilateral lung transplantation in rats

Modificação da técnica de alotransplante pulmonar unilateral em ratos

Pablo Gerardo Sánchez, Lucas Krieger Martins, Frederico Krieger Martins, Ricardo Schimer, Paulo Francisco Guerreiro Cardoso, Cristiano Feijó Andrade

J Bras Pneumol.2007;33(4):443-447

Abstract PDF PT PDF EN Portuguese Text Vídeo

The increasing demand in transplantation research requires efficient and less expensive animal models in order to obtain reliable results that are reproducible in larger animal models and, ultimately, applied clinically. The model of unilateral left lung transplantation in rats has proven to be a useful alternative for those purposes. We demonstrate a technical modification of this model, which consists of the isolation and ligation of the contralateral (right) pulmonary artery, allowing blood circulation exclusively in the transplanted lung. This model is feasible and reproducible. However, the short survival time restricts the assessment of the transplanted lung to a maximum period of three hours.

16 - The role of breastfeeding, diet and nutritional status in the development of asthma and atopy

O papel do aleitamento materno, da dieta e do estado nutricional no desenvolvimento de asma e atopia

Aline Petter Schneider, Renato Tetelbom Stein, Carlos Cezar Fritscher

J Bras Pneumol.2007;33(4):454-462

Abstract PDF PT PDF EN Portuguese Text

In many populations, the prevalence of asthma and atopy has increased in recent years. As a result, both conditions have become major public health problems. The possible influence of nutrition-related factors has been demonstrated in an increasing number of studies. Information regarding the role of breastfeeding, diet, nutritional status (obesity in particular), as well as regarding the immunologic responses triggered, helps to improve our understanding of the correlation between oxidative stress, bronchial inflammation, and the development of atopic and asthma symptoms. The article presents a review of the published literature on the relationships established between and among nutrition, asthma, and atopy over the last two decades.

17 - Pectus carinatum

Pectus carinatum

Marlos de Souza Coelho, Paulo de Souza Fonseca Guimarães

J Bras Pneumol.2007;33(4):463-474

Abstract PDF PT PDF EN Portuguese Text

Among the deformities of the thoracic wall,pectus carinatum has not received the same attention as has pectus excavatum. Few pulmonologists, pediatricians, and thoracic surgeons are aware of the approaches to treating this condition. As a consequence, patients with pectus carinatum are not referred for treatment. This deformity, with an incidence of 1:1000 teenagers, is oligosymptomatic. However, for aesthetic and emotional reasons, it accounts for a large number of medical appointments. Such patients are introverted and do not engage in physical activities, since they are unwilling to expose their chest, which also discourages them from going to the beach or to swimming pools. The diagnosis is clinical and visual, and details are obtained through chest X-rays and computed tomography. The treatment is based on a well-known organogram that summarizes orthopedic and surgical procedures. Dynamic compression, combined with physical exercises, is indicated for teenagers with flexible thorax in inferior and lateral pectus carinatum, with limited indication for those with superior pectus carinatum. For individuals of any age with rigid thorax, surgery is indicated for aesthetic reasons. Among the techniques described, the modified sternum chondroplasty stands out due to the excellent aesthetic results achieved.

Abstract PDF PT PDF EN Portuguese Text

Gastrobronchial fistula is a rare condition as a complication following bariatric surgery. The management of this condition requires the active participation of a pulmonologist, who should be familiar with aspects of the main types of bariatric surgery. Herein, we report the cases of two patients who presented recurrent subphrenic and lung abscess secondary to fistula at the angle of His for an average of 19.5 months. After relaparotomy was unsuccessful, cure was achieved by antibiotic therapy and, more importantly, by stenostomy and endoscopic dilatation, together with the use of clips and fibrin glue in the fistula. These pulmonary complications should not be treated in isolation without a gastrointestinal evaluation since this can result in worsening of the respiratory condition, thus making anesthetic management difficult during endoscopic procedures.

19 - Postemetic rupture of the esophagus: Boerhaave's syndrome

Ruptura pós-emética do esôfago: a síndrome de Boerhaave

Henrique José da Mota, Manoel Ximenes Netto, Aldo da Cunha Medeiros

J Bras Pneumol.2007;33(4):480-483

Abstract PDF PT PDF EN Portuguese Text

Postemetic rupture of the esophagus, also known as spontaneous rupture or Boerhaave's syndrome, was first described by Herman Boerhaave in 1724. This is a severe disease that causes high mortality rates and is difficult to diagnose not only because it is rare but also because it is frequently confused with other severe clinical conditions, such as acute myocardial infarction, perforated peptic ulcer, and acute pancreatitis. Herein, we describe three cases of patients with this syndrome. Two underwent primary repair of the rupture, and one underwent esophagectomy followed by reconstruction. There was one death due to septic shock in the immediate postoperative period. The other two patients presented favorable long-term evolution.

J Bras Pneumol.2007;33(4):484-486

Abstract PDF PT PDF EN Portuguese Text

Inflammatory pseudotumor of the lung is a rare form of benign neoplasia and is generally characterized by a solitary pulmonary nodule. The endobronchial presentation is uncommon. Conservative surgery remains the treatment of choice, and surgeons should always strive to achieve tumor-free margins due to the possibility of local recidivism. This article reports the case of a 36-year-old male patient with recurrent attacks of wheezing and cough. The patient underwent successful bronchoplasty for the resection of an endobronchial inflammatory pseudotumor.

21 - Fatal outcome in bronchus-associated lymphoid tissue lymphoma

Linfoma do tecido linfóide associado ao brônquio com evolução fatal

Romulo Loss Mattedi, Fabiola del Carlo Bernardi, Carlos Eduardo Bacchi, Sheila Aparecida Coelho Siqueira, Thais Mauad

J Bras Pneumol.2007;33(4):487-491

Abstract PDF PT PDF EN Portuguese Text

Primary pulmonary lymphoma is rare. The most common histological type is the bronchus-associated lymphoid tissue lymphoma. This type of lymphoma has an indolent course and excellent response to therapy. One-third of all cases are diagnosed incidentally. However, due to the rarity of this disease, little is known about its natural history in terms of dissemination and evolution. Herein, we report the unusual case of a 61-year-old man who refused treatment after being diagnosed with bronchus-associated lymphoid tissue lymphoma and died 2 years later from massive lung infiltration without dissemination to other organs.
