Objective: To analyze bronchoalveolar lavage (BAL) specimens of burn victims who inhaled smoke, in order to identify alterations associated with mortality or survival. Methods: Eighteen victims of facial burns were submitted to BAL up to 24 h after the event. We investigated cell and protein content, including TNF-α, HLA-DR, CD14, CD68 and iNOS. Results: Of the 18 patients submitted to bronchoscopy, 8 (44.4%) died during the follow-up period. The mean age of patients who died was significantly higher (44.7 vs. 31.5 years). On average, the patients who died had burns covering 60.1% of the total body surface area, compared with 26.1% in the survivors (p < 0.0001). Of the 18 patients submitted to bronchoscopy, 11 (61.1%) showed endoscopic signs of smoke inhalation injury, and 4 (36.4%) of those 11 died. Of the 7 patients with no signs of smoke inhalation injury, 4 (57.1%) died. The mean number of ciliated epithelial cells in the BAL fluid was significantly higher in the patients who died than in the survivors (6.6% vs. 1.4%; p = 0.03). There were no significant differences between the groups in terms of any of the other parameters evaluated. Conclusions: The total body surface area burned was a predictive factor for mortality. Increased numbers of ciliated epithelial cells in the BAL fluid, denoting bronchial epithelial desquamation, were associated with higher mortality in patients with facial burns.

A total of 287 bronchoscopies were performed in 267 patients infected with the human immunodeficiency virus (HIV). Bronchoalveolar lavage (BAL) and transbronchial biopsies (TBB) were sequentially performed in the same lung, in all cases. Specimens were examined after routine laboratory procedures for microbiologic and histologic analysis. Age ranged from 16 to 78 (median 37.2); 228 were men (85.4%) and 39 were women. Dyspnea was the main symptom in 198 cases (69.0%) and interstitial infiltrates (diffuse or localized) were the most common findings at chest radiographs (179 patients, 62.4%). Endoscopic view was normal in 246 patients (85.7%). Mucosal lesions suggestive of Kaposi's sarcoma (KS) were visible in 12 cases (4.2%). BAL detected 97 infectious agents, simultaneous co-infection occurred in 3 cases. TBB identified 165 pathogens (9 of them in association), anticipating a better yield than BAL in the diagnosis of P. carinii (84 versus 51, respectively) and cytomegalovirus (35 v. 0). Biopsies were unique in establishing the appropriate diagnosis of extrabronchial cancer and describing inespecific pneumonitis. Altogether, a definite diagnosis was obtained by bronchoscopic examination (including endoscopic view, BAL and TBB) in 271 of 287 cases (94.4%). Infections were caused by P. carinii in 105 patients (36.6%), Mycobacterium sp in 40 (13.9%), cytomegalovirus in 35 (12.2%), C. neoformans in 13 (4.5%) etc. Malignancies (including KS) were found in 16 patients (5.6%). More than one pathologic process was present in 28 (9.8%). Nonspecific pneumonitis was diagnosed in 56 cases (19.5%) and normal lung in 20 (7.0%). Complications related to bronchoscopy were pneumothorax (8 patients, 2.8%), haemorrhage (8), thoracic pain (2) and distal pneumonia (2). Chest tubes were required in 4 patients, including one fatal case (mortality rate of 0.3%). Combining BAL and TBB results increases the diagnostic yield of bronchoscopy in AIDS, with a low complication rate. If both techniques are performed, a higher number of infectious agents and more multiple causes of pulmonary disease may be identified.

Background: Pulmonary involvement is common in leptospirosis and usually characterized by hemoptysis, dyspnea and diffuse bilateral infiltrates in chest X-rays. Such findings may be compatible with alveolar hemorrhage, already described by some authors both in autopsies and bronchoalveolar lavage (BAL). Objective: To evaluate the presence of alveolar hemorrhage, diagnosed through BAL, in bearers of leptospirosis patients with pulmonary involvement emphasizing the method's importance for early detection of this complication. Method: Seven patients with leptospirosis were submitted to BAL. All presented respiratory symptoms and/or infiltrates in the chest X-rays and/or hypoxemia. Alveolar hemorrhage was defined by the following findings in BAL: percentage of siderophages e"20% and/or Golde score >100 and/or hemorrhagic fluid. Culture and direct tests for leptospirosis were performed in BAL. Diagnosis of disease was confirmed by microscopy serum agglutination. Results: The aspect of the bronchoscopy was normal in five patients, showed blood in the bronchial tree in one case and inflammatory manifestations in another. The BAL aspect was hemorrhagic for all patients portraying alveolar hemorrhage. Culture and direct tests were negative for Leptospiras in the BAL. Conclusions: Leptospirosis must be taken into account in the differential diagnosis of alveolar hemorrhage. The BAL was confirmed as an efficient method for detection of alveolar hemorrhage in leptospirosis, to recommend immediate therapy for the purpose of preventing its evolution to massive hemoptysis and respiratory failure.

Bronchoalveolar lavage is a safe and simple technique to evaluate lung disease related to exposure to mineral dusts. The aim of this study was to characterize the lymphocyte subsets in bronchoalveolar lavage of patients with silicosis. Bronchoalveolar lavage was carried out in 26 workers with different forms of silicosis: simple form (n = 12), complicated (n = 13) and 1 patient with acute form of the disease. As a control group, 7 healthy individuals were included. Compared to the control group, silicotic patients showed intense pleocytosis constituted mainly by alveolar macrophages with slight lymphocytosis. Lymphocyte subsets present in the bronchoalveolar fluid (BAL) of normal individuals were mature lymphocytes with phenotype CD2+TCRab (87.3%) and only 2.9% were CD2+TCRgd. CD4/CD8 ratio was 1.8 with few (16%) immature double negative T cells subsets (CD4-CD8-). In contrast, silicotic patients showed reduction of the more mature lymphocyte subset CD2+CD4+, CD2+CD8+ and a great increase (47%) of immature (CD4-CD8-) T cell subsets. No increase in the NK (CD56+) cell population was observed. Biochemical analysis of protein contents and determination of the Ig/albumin ratio characterized local immunoglobulin production within the pulmonary microenvironment. Furthermore, lack of increase of plasma cells, as well as the maintenance of the percentage of B lymphocyte population (CD19+) in the BAL of silicotic patients, favors the hypothesis that the cells responsible for Ig production are possibly located in the interstitial space. Altogether the results suggest development of lymphopoiesis and tertiary lymphoid tissue within the pulmonary microenvironment during the clinical course of silicosis.

Objective: To present aspects of the evolution of lipoid pneumonia in children, based on clinical, radiological and bronchoalveolar lavage fluid findings, emphasizing the importance of bronchoalveolar lavage for the diagnosis and treatment. Methods: We included 28 children, with a mean age of 20 months (range, 1-108 months), diagnosed with chronic pneumonia refractory to antimicrobial therapy, with TB or with a combination of the two. Most of the children had at least one risk factor for aspiration, and all of them had a history of mineral oil ingestion for intestinal constipation (23/28) or complicated ascaridiasis (5/28). Clinical evaluations, tomographic evaluations and analyses of bronchoalveolar lavage fluid were carried out at the beginning of treatment and throughout a follow-up period of 24 months. Results: Tachypnea and cough were the most common symptoms. The most common radiological alterations were areas of consolidation (23/28), perihilar infiltrates (13/28) and hyperinflation (11/28). Chest CT scans showed areas of consolidation with air bronchogram (24/28), decreased attenuation in the areas of consolidation (16/28), ground-glass opacities (3/28) and crazy-paving pattern (1/28). In the analysis of the bronchoalveolar lavage fluid, Sudan staining revealed foamy macrophages, confirming the diagnosis of lipoid pneumonia. After treatment with multiple bronchoalveolar lavages (mean = 9.6), 20 children became asymptomatic, 18 of those presenting normal tomographic images. Conclusions: A diagnosis of lipoid pneumonia should be considered in patients with chronic refractory pneumonia or TB, especially if there is a history of mineral oil ingestion. Bronchoscopy with multiple bronchoalveolar lavages was an efficient treatment for the clearance of mineral oil from the lung parenchyma and the prevention of fibrosis. This strategy contributed to reducing the morbidity of lipoid pneumonia, which remains a rare diagnosis.

Tuberculosis continues to be a major public health problem worldwide. The aim of the present study was to evaluate the accuracy of the Xpert MTB/RIF rapid molecular test for tuberculosis, using pulmonary samples obtained from patients treated at the Júlia Kubitschek Hospital, which is operated by the Hospital Foundation of the State of Minas Gerais, in the city of Belo Horizonte, Brazil. This was a retrospective study comparing the Xpert MTB/RIF test results with those of standard culture for Mycobacterium tuberculosis and phenotypic susceptibility tests. Although the Xpert MTB/RIF test showed high accuracy for the detection of M. tuberculosis and its resistance to rifampin, attention must be given to the clinical status of the patient, in relation to the test results, as well as to the limitations of molecular tests.

In 1993 the first Brazilian cluster of Hantavirus Cardiopulmonary Syndrome (HCPS) was described in Juquitiba, SP. Since then, there have been descriptions of new cases specially on the southeast and south states of Brazil. Only in 2002 there were observed the first three cases of HCPS in our city: São Carlos. One of our patients was successfully supported with CPAP through facial mask. This is the first severe case of acute respiratory failure induced by Hantavirus that was successfully managed with this kind of respiratory strategy.

Objective: To study the effects of an oronasal interface (OI) for noninvasive ventilation, using a three-dimensional (3D) computational model with the ability to simulate and evaluate the main pressure zones (PZs) of the OI on the human face. Methods: We used a 3D digital model of the human face, based on a pre-established geometric model. The model simulated soft tissues, skull, and nasal cartilage. The geometric model was obtained by 3D laser scanning and post-processed for use in the model created, with the objective of separating the cushion from the frame. A computer simulation was performed to determine the pressure required in order to create the facial PZs. We obtained descriptive graphical images of the PZs and their intensity. Results: For the graphical analyses of each face-OI model pair and their respective evaluations, we ran 21 simulations. The computer model identified several high-impact PZs in the nasal bridge and paranasal regions. The variation in soft tissue depth had a direct impact on the amount of pressure applied (438-724 cmH2O). Conclusions: The computer simulation results indicate that, in patients submitted to noninvasive ventilation with an OI, the probability of skin lesion is higher in the nasal bridge and paranasal regions. This methodology could increase the applicability of biomechanical research on noninvasive ventilation interfaces, providing the information needed in order to choose the interface that best minimizes the risk of skin lesion.

Objective: To compare gastric lavage (GL) performed in inpatients with GL performed in outpatients in terms of its accuracy in diagnosing pulmonary tuberculosis (TB) in children. Methods: A prospective study was carried out in the state of Espírito Santo, Brazil, from 1999 to 2003. A total of 230 children suspected of having TB (103 inpatients and 127 outpatients) were selected to undergo GL. Those thus diagnosed with TB (n = 53) were divided into two groups: inpatient GL (n = 30) and outpatient GL (n = 23). All 53 children were monitored for 6 months in order to evaluate the accuracy of the diagnosis. Accuracy was determined based on any change in diagnosis, cure rate, and the percentage of positive cultures in the two groups studied. Results: The cure rate was 100% in both groups, and there was no change in diagnosis in the 53 children studied. No significant difference was found between the two groups studied in terms of detection of Mycobacterium tuberculosis (RR = 1.47; 95% CI: 0.95-2.27; p = 0.095), although the outpatient group presented a greater rate of positive cultures. Conclusions: Our results show that the accuracy of GL performed in an inpatient setting is similar to that of GL performed in an outpatient setting. This indicates that hospitalization is required only in more severe cases in which GL cannot be performed as an outpatient procedure.

Objective: To determine the characteristics of individuals with asthma who are responsive to aerobic training. Methods: This post hoc analysis of pooled data from previous randomized controlled trials involved 101 individuals with moderate to severe asthma who underwent aerobic training. Participants underwent a maximal cardiopulmonary exercise test and completed the Asthma Control Questionnaire and the Asthma Quality of Life Questionnaire before and after a 24-session aerobic training program. Better and worse responders to aerobic training were identified by cluster analysis. Results: Two clusters were identified according to the improvement in peak VO2 after aerobic training (better and worse responders). Characteristics of the better responder group were being older, being female, having higher BMI, and having higher cardiac reserve at baseline when compared with the worse responder group. Also, better responders had worse clinical control, worse quality of life, and lower physical capacity at baseline. After training, worse responders, in comparison with better responders, showed half the improvement in ?peak VO2 (7.4% vs. 13.6%; 95% CI, -12.1 to -0.92%; p < 0.05) and worse asthma control. A weak, negative, but significant association (r = -0.35; p < 0.05) was observed between clinical control and aerobic fitness only in the better responder group. Both groups showed significant improvement in quality of life. Conclusions: Obese individuals with worse exercise capacity, clinical control, and quality of life showed improvement with aerobic training. Moreover, worse responders also improved with training, but to a lesser extent.

Objective: Failure of noninvasive ventilation (NIV) has been associated with short-term adverse effects related to the use of masks. The aim of this study was to compare the incidence, type and intensity of adverse effects, as well as the comfort, of total face masks (TFMs), facial masks (FMs) and nasal masks (NMs) during NIV. Methods: This was a randomized crossover trial involving 24 healthy volunteers submitted to six sessions of NIV in bilevel positive airway pressure mode using the TFM, FM and NM masks at low and moderate-to-high pressure levels. A written questionnaire was applied in order to evaluate eleven specific adverse effects related to the use of the masks. Comfort was assessed using a visual analog scale. The CO2 exhaled into the ventilator circuit was measured between the mask and the exhalation port. Results: The performance of the TFM was similar to that of the NM and FM in terms of comfort scores. Higher pressure levels reduced comfort and increased adverse effects, regardless of the mask type. When the TFM was used, there were fewer air leaks and less pain at the nose bridge, although there was greater oronasal dryness and claustrophobia. Air leaks were most pronounced when the FM was used. The partial pressure of exhaled CO2 entering the ventilator circuit was zero for the TFM. Conclusions: The short-term adverse effects caused by NIV interfaces are related to mask type and pressure settings. The TFM is a reliable alternative to the NM and FM. Rebreathing of CO2 from the circuit is less likely to occur when a TFM is used.

Objective: To compare the incidence and intensity of acute adverse effects and the variation in the temperature of facial skin by thermography after the use of noninvasive ventilation (NIV). Methods: We included 20 healthy volunteers receiving NIV via oronasal mask for 1 h. The volunteers were randomly divided into two groups according to the ventilatory mode: bilevel positive airway pressure (BiPAP) or continuous positive airway pressure (CPAP). Facial thermography was performed in order to determine the temperature of the face where it was in contact with the mask and of the nasal dorsum at various time points. After removal of the mask, the volunteers completed a questionnaire about adverse effects of NIV. Results: The incidence and intensity of acute adverse effects were higher in the individuals receiving BiPAP than in those receiving CPAP (16.1% vs. 5.6%). Thermographic analysis showed a significant cooling of the facial skin in the two regions of interest immediately after removal of the mask. The more intense acute adverse effects occurred predominantly among the participants in whom the decrease in the mean temperature of the nasal dorsum was lower (14.4% vs. 7.2%). The thermographic visual analysis of the zones of cooling and heating on the face identified areas of hypoperfusion or reactive hyperemia. Conclusions: The use of BiPAP mode was associated with a higher incidence and intensity of NIV-related acute adverse effects. There was an association between acute adverse effects and less cooling of the nasal dorsum immediately after removal of the mask. Cutaneous thermography can be an additional tool to detect adverse effects that the use of NIV has on facial skin.

Objective: Studies assessing the characteristics and management of patients hospitalized with asthma have been limited to a small number of facilities and have evaluated short time periods. The present study evaluated long-term changes among hospitalized asthma patients at a large number of facilities. Methods: This was a retrospective, hospital-based observational case series, designated the Study of Severe Asthma in Latin America and Spain, which was conducted in Spain and in eight Latin-American countries. We reviewed the hospital records of 3,038 patients (age range, 15-69 years) hospitalized with acute severe asthma at one of nineteen tertiary-care hospitals in 1994, 1999 and 2004. Results: Over time, the use of inhaled corticosteroids and long-acting β2 agonists increased significantly, whereas the use of theophylline as a controller medication decreased. The utilization of pulmonary function tests also increased. There was a significant reduction in the mean hospital stay (8.5 days, 7.4 days and 7.1 days in 1994, 1999 and 2004, respectively, p = 0.0001) and a significant increase in the mean of the lowest arterial pH at hospital admission. In contrast, there was a significant decrease in the proportion of cases in which PEF was determined in the emergency room (48.6% in 1994 vs. 43.5% in 2004, p = 0.0001). We found the quality of asthma management and care to be generally better in Spain than in Latin America. Conclusions: Although there have been certain improvements in the management of asthma between severe exacerbations and during hospitalization, asthma management remains suboptimal in Spain and, especially, in Latin America.

Background: Massive hemoptysis is a high morbidity and high mortality condition, independently of the treatment administered. A variety of methods are used to control the acute bleeding. The instillation of iced saline solution through a rigid bronchoscope was described in 1980. Objective: To establish the efficacy of repeated instillations of iced saline solution (4oC) using a rigid bronchoscope for the acute control of massive hemoptysis. Method: A group of 94 patients with massive hemoptysis was treated with rigid bronchoscopy and lavage with iced saline solution of the actively bleeding lung. The absence of bleeding recurrence within the following 15 days was considered a therapeutic success. The causes of hemoptysis included: pulmonary tuberculosis: 78 (83%), among which 48 had active disease, and 30 had tuberculosis sequelae, bronchiectasis (6), lung cancer (5), intracavitary aspergilloma (3), and unknown (2). The bleeding site was found in 93 patients (99%). The mean saline volume used in the bronchoscopy was 528 mL, ranging from 160 mL to 2,500 mL. Results: All patients stopped bleeding during the procedure. Fifteen patients were submitted to some kind of procedure (surgery, embolization, or radiation therapy) within 15 days, and the efficacy of lavage could not be assessed. Twenty of the 79 patients followed-up for more than 15 days had recurrence of hemoptysis. Cold saline lavage was repeated once in 13 patients, twice in 6 patients, and 3 times in one patient. Conclusion: The control of tracheobronchial hemorrhage through bronchoscopy and lavage with iced saline is an effective procedure and can be repeated in case of re-bleeding. It is a safe procedure, and allows the definitive treatment to occur in better clinical conditions.

Objective: To characterize clinical phenotypes of severe asthma. Methods: A total of 111 patients were retrospectively evaluated at a specialized outpatient clinic. A systematic protocol for patient evaluation and follow-up was applied. Treatment compliance and control of the disease at the end of follow-up were defined by clinical and functional data. Patients who did not meet asthma control criteria after six months despite compliance with treatment and correct use of medication were characterized as treatment-resistant. Phenotypes were determined by factorial analysis and compared using various tests. Results: At the end of follow-up, 88 patients were considered treatment compliant and 23 were considered noncompliant. Factorial analysis of the compliant patients identified four phenotypes: phenotype 1 (28 patients) comprised patients who were treatment-resistant, more often presenting nocturnal symptoms and exacerbations, as well as more often using rescue bronchodilators; phenotype 2 (48 patients) comprised patients with persistent airflow limitation, lower ratios of forced expiratory volume in one second/forced vital capacity at baseline, more advanced age and longer duration of symptoms; phenotype 3 (42 patients) comprised patients with allergic rhinosinusitis who were nonsmokers and presented predominantly reversible airflow obstruction; and phenotype 4 (15 patients) comprised cases with a history of aspirin intolerance to acetylsalicylic acid associated with near-fatal asthma. Conclusions: A significant number of patients with severe asthma are noncompliant with treatment. Although many patients with severe asthma have persistent airflow obstruction, the most relevant clinical phenotype comprises patients who are resistant to the typical treatment.

Objective: To determine whether pulmonary mechanics are altered in mice with sepsis. Methods: A total of 40 Balb/c mice were divided into two groups: survival (n = 21) and pulmonary mechanics (n = 19). The survival group was divided into three subgroups: control (n = 7), sublethal (n = 7) and lethal (n = 7). The pulmonary mechanics group was also divided into three subgroups: control (n = 5), sublethal (n = 7) and lethal (n = 7). Sepsis was induced through cecal ligation and puncture, the latter varying in degree (sublethal or lethal). At eight hours after the intervention, pulmonary mechanics were measured through end-inflation occlusion. In the pulmonary mechanics group, the following variables were studied: total pressure, resistance, viscoelasticity, dynamic compliance and static compliance. The data obtained were analyzed using one-way ANOVA. Results: The data for the survival group indicate the efficacy of the model employed. There were no statistically significant differences among the pulmonary mechanics subgroups in terms of dynamic compliance, static compliance, total pressure, resistance or viscoelasticity. Conclusion: At eight hours after cecal ligation and puncture, there were no changes in the lung parenchyma, nor were any alterations observed in the viscous and viscoelastic components of the lung.

Objective: Evaluate the efficacy of the ampicillin-quinolone association in the treatment of severe community-acquired pneumonia. Design: Open, prospective study carried out at the Emergency room of the Hospital Universitário da Universidade Federal de Juiz de Fora. Patients and methods: From March 1994 to September 1995, the authors studied 23 patients with fever and with at least three of the following symptoms: cough, purulent sputum, pleuritic thoracic pain, leukocytosis or leukopenia, and a chest radiological examination showing infiltrations compatible with pneumonia diagnosis. The patient diagnosis would be severe pneumonia if he met the criteria of severe sepsis as established by the American College of Chest Physicians and by the Society of Critical Care Medicine. Results: 23 patients were studied. One was excluded after having a pulmonary tuberculosis diagnosis; 21 patients were considered cured and one died. Adverse drug effects occurred in one patient who presented a mild pharmacodermia. Conclusion: Ampicillin-quinolone is efficient in the treatment of severe community-acquired pneumonia.

Objective: To identify, characterize, and quantify associations of various factors with quality of life (QoL) in patients with asthma, according to the pharmacotherapy employed. Methods: This was a cross-sectional study involving 49 patients (≥ 18 years of age) with severe uncontrolled or refractory asthma treated at a specialized outpatient clinic of the Brazilian Unified Health Care System, regularly using high doses of inhaled corticosteroids (ICs) or other medications, and presenting comorbidities. At a single time point, QoL was assessed with the Asthma Quality of Life Questionnaire (AQLQ). The overall AQLQ score and those of its domains were correlated with demographic variables (gender and age); Asthma Control Questionnaire score; pharmacotherapy (initial IC dose, inhaler devices, and polytherapy); and comorbidities. Results: Better AQLQ scores were associated with asthma control-overall (OR = 0.38; 95% CI: 0.004-0.341; p < 0.001), "symptoms" domain (OR = 0.086; 95% CI: 0.016-0.476; p = 0.001), and "emotional function" domain (OR = 0.086; 95% CI: 0.016-0.476; p = 0.001)-and with IC dose ≤ 800 µg-"activity limitation" domain (OR = 0.249; 95% CI: 0.070-0.885; p = 0.029). Worse AQLQ scores were associated with polytherapy-"activity limitation" domain (OR = 3.651; 95% CI: 1.061-12.561; p = 0.036)-and number of comorbidities ≤ 5-"environmental stimuli" domain (OR = 5.042; 95% CI: 1.316-19.317; p = 0.015). Conclusions: Our results, the importance of this issue, and the lack of studies taking pharmacotherapy into consideration warrant longitudinal studies to establish a causal relationship between the identified factors and QoL in asthma patients.
