Objective: To evaluate the impact of a 5-day educational camp program for children with asthma in terms of improving their knowledge of asthma and enhancing their performance in the use of inhaled medication and in physical activities. Methods: Every day, the children received 20-min interactive educational sessions, the technique for using the metered-dose inhaler was reviewed, two peak flow readings were recorded, and the children performed physical activities that included breathing and relaxation exercises. A questionnaire regarding knowledge of asthma, as well as asthma triggers, asthma medications, misconceptions regarding asthma, and the use of spacers, was administered before and after the intervention. Correct use of inhaled medication and exercise-related symptoms were also evaluated before and after the intervention. Results: A total of 37 children with asthma, aged 8-10 years (15 females and 22 males), were included in this study. Of those, 25% showed an improvement in the level of knowledge of asthma after the educational camp program, as evidenced by the greater number of correct answers on three of the twelve questions analyzed (p < 0.05). The exercise-related dyspnea scores decreased significantly (p < 0.05). The ability to use inhaled medication correctly was significantly improved after the intervention (p < 0.05). Conclusions: The asthma educational camp program can improve knowledge about specific questions, encourage participation in physical activities, and improve the asthma management skills of children.

Objective: To analyze clinical and radiological findings that influence the pathological diagnosis of solitary pulmonary nodule (SPN) and to compare/validate two probabilistic models for predicting SPN malignancy in patients with SPN in Brazil. Methods: This was a retrospective study involving 110 patients diagnosed with SPN and submitted to resection of SPN at a tertiary hospital between 2000 and 2009. The clinical characteristics studied were gender, age, presence of systemic comorbidities, history of malignancy prior to the diagnosis of SPN, histopathological diagnosis of SPN, smoking status, smoking history, and time since smoking cessation. The radiological characteristics studied, in relation to the SPN, were presence of spiculated margins, maximum transverse diameter, and anatomical location. Two mathematical models, created in 1997 and 2007, respectively, were used in order to determine the probability of SPN malignancy. Results: We found that SPN malignancy was significantly associated with age (p = 0.006; OR = 5.70 for age > 70 years), spiculated margins (p = 0.001), and maximum diameter of SPN (p = 0.001; OR = 2.62 for diameters > 20 mm). The probabilistic model created in 1997 proved to be superior to that created in 2007-area under the ROC curve, 0.79 ± 0.44 (95% CI: 0.70 0.88) vs. 0.69 ± 0.50 (95% CI: 0.59-0.79). Conclusions: Advanced age, greater maximum SPN diameter, and spiculated margins were significantly associated with the diagnosis of SPN malignancy. Our analysis shows that, although both mathematical models were effective in determining SPN malignancy in our population, the 1997 model was superior.

Aline Arlindo Vieira, Ilka Lopes Santoro, Samir Dracoulakis, Lilian Ballini Caetano, Ana Luisa Godoy Fernandes

J Bras Pneumol.2011;37(1):13-18

Abstract PDF PT PDF EN Portuguese Text

Objective: There is evidence that asthma is associated with an increase in psychiatric symptoms and mental disorders. This association can make it difficult to achieve asthma control. The purpose of this study was to determine whether the level of asthma control is associated with anxiety and depression. Methods: A cross-sectional study involving 78 patients with confirmed moderate or severe asthma and under regular treatment at the Asthma Outpatient Clinic of the Federal University of São Paulo Hospital São Paulo, in the city of São Paulo, Brazil. The patients were divided into two groups by asthma control status, as assessed by the asthma control test, and were subsequently compared in terms of demographic, clinical, and spirometric data, as well as scores for asthma quality of life and hospital anxiety/depression. Results: The sample was predominantly female. Of the 78 patients, 49 (63%) were classified as having uncontrolled asthma. The prevalence of anxiety and of anxiety+depression was significantly higher among patients with uncontrolled asthma than among those with controlled asthma (78% and 100%; p = 0.04 and p = 0.02, respectively), whereas there were no differences between the two groups in terms of the prevalence of depression, spirometry results, or quality of life score. Conclusions: In this sample, the prevalence of anxiety symptoms was higher in the patients with uncontrolled asthma than in those with controlled asthma.In the evaluation of asthma patients, the negative impact of mood states ought to be taken into consideration when asthma control strategies are being outlined.

Objective: To assess the quality of life of patients with lung cancer and to compare it with that of individuals without cancer. Methods: The Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) was administered to 57 patients diagnosed with lung cancer, treated at the Lung Cancer Outpatient Clinic of the Hospital São Paulo, and to a control group of 57 individuals recruited from the Extra Penha workout group. The Mann-Whitney test was used to compare the groups, domain by domain. The first model of logistic regression was adjusted for male gender, nonsurgical treatment, Karnofsky performance status and smoking, which were included as predictors. The second model was adjusted for each SF-36 domain in order to identify increases in the proportions of patients in stage IIIB or IV. Results: The lung cancer group and the control group presented the following mean scores, respectively, for the SF-36 domains: role limitations due to physical health problems, 29.39 ± 36.94 and 82.89 ± 28.80; role limitations due to emotional problems, 42.78 ± 44.78 and 86.55 ± 28.77; physical function, 56.49 ± 28.39 and 89.00 ± 13.80; vitality, 61.61 ± 23.82 and 79.12 ± 17.68; bodily pain, 62.72 ± 28.72 and 81.54 ± 19.07; general health, 62.51 ± 25.57 and 84.47 ± 13.47; emotional well-being, 68.28 ± 23.46 and 82.63 ± 17.44; and social functioning, 72.87 ± 29.20 and 91.67 ± 17.44. The logistic regression model showed that role limitations due to physical health problems, physical function and emotional well-being were predictors of stages IIIB and IV. Conclusions: The patients with lung cancer had a poorer quality of life, especially regarding physical aspects, than did the control subjects.

Objective: To evaluate paranasal sinuses in patients with stable or acute asthma in order to determine the prevalence of acute bacterial rhinosinusitis. Methods: A cross-sectional study including 30 patients with acute asthma (73% females) treated in the emergency room and 30 patients with stable asthma (80% females) regularly monitored as outpatients. All patients completed a questionnaire on respiratory signs and symptoms and were submitted to ear, nose and throat (ENT) examination, as well as to X-ray and computed tomography (CT) imaging of the sinuses. Results: Based on the clinical diagnosis, the prevalence of acute bacterial rhinosinusitis was 40% in the patients with acute asthma and 3% in those with stable asthma. The ENT examination findings and the imaging findings in isolation were not useful to confirm the diagnosis. Conclusions: In themselves, ENT examination findings, X-ray findings and CT findings were not useful for the diagnosis of acute bacterial rhinosinusitis. Our results provide further evidence that a clinical diagnosis of bacterial rhinosinusitis should be made with caution.

Abstract PDF PT PDF EN Portuguese Text

Objective: To evaluate the capacity of the criteria described in Complementary Directive SAS/MS 12, issued on November 12, 2002, to identify patients with severe asthma, describing and comparing clinical, functional and treatment data of such patients. Methods: This was a nested case-control study using a structured database for adult asthma outpatients. We defined cases as asthma patients who met the inclusion criteria described in the directive, defining controls as those who did not. We collected and compared data related to the following: demographic characteristics; history of asthma; medications in use; comorbidities; history of tobacco use; number of exacerbations within the last 12 months, asthma-related hospitalizations and intensive care unit admissions within the last 12 months; spirometry; and sputum cytology. Results: The case and control groups consisted of 29 and 31 patients, respectively. The number of asthma exacerbations and emergency room visits within the last 12 months, as well as the number of patients that received at least one pulse of oral corticosteroids, was significantly higher in the case group than in the control group. In addition, prebronchodilator FVC was lower among the cases than among the controls. Furthermore, cytology revealed that eosinophil counts were significantly higher in the induced sputum of cases than in that of controls. Conclusions: The criteria described in the directive are suited to stratifying patients with severe asthma.

Nutritional evaluation in patients with lung cancer

Avaliação nutricional em pacientes portadores de câncer de pulmão

Sérgio Jamnik, Cesar Uehara, Ilka Lopes Santoro

J Bras Pneumol.1998;24(6):347-353

Abstract PDF PT

The authors analyze the nutritional status of patients with lung cancer. 131 patients, 96 (73.3%) male and 35 (26.7%) female, were classified into three groups: I - malnourished patients; II - eutrophic patients and III - obese patients. Most of the malnourished had anorexia (59.7%), which was not seen in the eutrophic (25%) and obese patients (26.1%). More than 70% of patients reported some degree of previous weight loss at the initial evaluation, weight loss being higher among malnourished patients. Weight loss was observed in more than 60% of the patients during the follow-up period of 3 months after the first evaluation. Patients with squamous carcinoma neoplasms prevailed in the malnourished group whereas adenocarcinoma was more prevalent in the other two groups. Most patients had advanced stages of the disease.

Bronchiectasis: a study of 314 cases tuberculosis x non-tuberculosis

Bronquiectasias: estudo de 314 casos tuberculose x não-tuberculose

Miguel Bogossian, Ilka Lopes Santoro, Sérgio Jamnik, Hélio Ramaldini

J Bras Pneumol.1998;24(1):11-16

Abstract PDF PT

The authors studied 314 patients with bronchiectasis. An elevated percentage of sequelae of tuberculosis (42.7%) was found, and other causes of bronchiectasis represented 57.3%. Mean age was similar in both groups, around 50 years old, with predominance of females (65.0%). As to symptoms and signs, hemoptysis was sharply predominant in the tuberculosis group (37.3% x 22.8%; p < 0.05). Association between asthma and infections during childhood was similar in both groups, but sinusitis was more frequent in the non-tuberculosis group (45.0% x 23.9%; p < 0.05). The most frequent site for bronchiectasis secondary tuberculosis was the right upper lobe; in the other group, the most frequent sites were lower left lobe and lingula. The most frequent morphologic type in greater groups was cylindrical (more than 50% of patients). Lung function tests were abnormal, with reduction in both FEV 1 and FVC in the tuberculosis group. Forty-four percent of the patients in the first group and 37.2% in the second one were smokers. The authors make comments about the high number of patients with tuberculosis scars that have secondary bronchiectasis and the greater impairment of lung function in this group of patients.

Abstract PDF PT PDF EN Portuguese Text

Objective: There is an indirect relationship between airway obstruction in asthma and the intensity of breathlessness (dyspnea). A word labeled visual analog dyspnea scale with a 0-3 score has been widely used for the assessment of the degree of bronchoconstriction, although the perception of such obstruction varies considerably. The objective of this study was to determine whether children and adolescents are able to perceive acute exercise-induced bronchoconstriction (EIB), as well as to measure the discriminatory power of a word labeled visual analog dyspnea scale in relation to the intensity of the EIB. Methods: A cross-sectional study involving 134 children and adolescents with asthma and submitted to a six-minute steady-state exercise test on a cycle ergometer. The intensity of dyspnea was determined using a word labeled visual analog dyspnea scale prior to each determination of FEV1. The scale is scored from 0 to 3, with a logical sequence of pictures, ranging from "no symptoms" to "severe dyspnea". Variables were determined at baseline, as well as at 5, 10, and 20 min after the exercise test. The accuracy of the dyspnea scale in identifying the degree of EIB was determined by means of ROC curves for the post-exercise fall in FEV1, using cut-off points of 10%, 20%, 30%, and 40%. Results: Of the patients selected, 111 finished the study, and 52 (46.8%) presented with EIB. The area under the ROC curve increased in direct proportion to increases in the degree of bronchoconstriction. Conclusions: Among children and adolescents with asthma, the accuracy of this dyspnea scale improves as the post-exercise percentage fall in FEV1 increases. However, the predictive value of the scale is suboptimal when the percentage fall in FEV1 is lower.

J Bras Pneumol.2002;28(5):245-249

Abstract PDF PT

Despite the improvements seen in the treatment of lung cancer, little has improved in the survival of these patients, and a great importance is attributed to the factors that have a role to play in such survival. Purpose: To check for possible prognostic factor differences in two populations of lung cancer patients, one of them with short survival (less than six months), and the other with longer survival (more than 24 months). Methods: From 1997 to 1999, 52 patients with histopathologic diagnosis of homogenous carcinoma were studied, and demographics, clinical parameters, smoking pattern, Karnofsky's index, disease staging, and laboratory dosing of lactic dehydrogenase, alkaline phosphatase, carcinoembryonic antigen, and calcium data were surveyed. Results: 29 patients had less than six month survival, and 23 had more than 24 month survival. The three most important factors for short survival were the low initial Karnofsky's index, loss of appetite, and high serum LDH levels. Conclusion: The three prognosis components are: current physical status, prior physical status, and current status of the disease.

Objective: To determine whether the use of a set of preoperative variables can predict the need for postoperative ICU admission. Methods: This was a prospective observational cohort study of 120 patients undergoing elective pulmonary resection between July of 2009 and April of 2012. Prediction of ICU admission was based on the presence of one or more of the following preoperative characteristics: predicted pneumonectomy; severe/very severe COPD; severe restrictive lung disease; FEV1 or DLCO predicted to be < 40% postoperatively; SpO2 on room air at rest < 90%; need for cardiac monitoring as a precautionary measure; or American Society of Anesthesiologists physical status ≥ 3. The gold standard for mandatory admission to the ICU was based on the presence of one or more of the following postoperative characteristics: maintenance of mechanical ventilation or reintubation; acute respiratory failure or need for noninvasive ventilation; hemodynamic instability or shock; intraoperative or immediate postoperative complications (clinical or surgical); or a recommendation by the anesthesiologist or surgeon to continue treatment in the ICU. Results: Among the 120 patients evaluated, 24 (20.0%) were predicted to require ICU admission, and ICU admission was considered mandatory in 16 (66.6%) of those 24. In contrast, among the 96 patients for whom ICU admission was not predicted, it was required in 14 (14.5%). The use of the criteria for predicting ICU admission showed good accuracy (81.6%), sensitivity of 53.3%, specificity of 91%, positive predictive value of 66.6%, and negative predictive value of 85.4%. Conclusions: The use of preoperative criteria for predicting the need for ICU admission after elective pulmonary resection is feasible and can reduce the number of patients staying in the ICU only for monitoring.

Abstract PDF PT PDF EN

Objective: Lung cancer patients often experience profound physical and psychosocial changes as a result of disease progression or treatment side effects. Fatigue, pain, dyspnea, depression, and sleep disturbances appear to be the most common symptoms in such patients. The objective of the present study was to examine the prevalence of symptoms in lung cancer patients in order to identify subgroups (clusters) of patients, grouped according to the magnitude of the symptoms, as well as to compare the quality of life among the identified subgroups. Methods: A cross-sectional study involving agglomerative hierarchical clustering. A total of 50 lung cancer patients were evaluated in terms of their demographic characteristics and their scores on three quality of life questionnaires, namely the 30-item European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30), the Functional Assessment of Cancer Therapy-Lung, and the Medical Outcomes Study 36-item Short-form Survey. The cluster analysis took into account the magnitude of the most prevalent symptoms as assessed by the EORTC QLQ-C30 symptom scale scores; those symptoms were fatigue, pain, dyspnea, and insomnia. Results: Three clusters (subgroups)_of patients were identified on the basis of the magnitude of the four most prevalent symptoms. The three subgroups of patients were as follows: patients with mild symptoms (n = 30; 60%); patients with moderate symptoms (n = 14; 28%); and patients with severe symptoms (n = 6; 12%). The subgroup of patients with severe symptoms had the worst quality of life, as assessed by the total scores and by the integrated domains of all three instruments. Conclusions: This study highlights the importance of symptom cluster assessment as an important tool to assess the quality of life of patients with chronic diseases, such as lung cancer.

Abstract PDF PT PDF EN Portuguese Text

Objective: The assessment of the quality of life in patients with lung cancer has become one of the main goals in current clinical trials. To assess the quality of life of these patients, the most widely used instrument is the 30-item European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) in conjunction with its supplemental 13-item lung cancer-specific module (QLQ-LC13). The objective of this study was to assess the reproducibility of the Brazilian Portuguese version of these questionnaires. Methods: A prospective study involving 30 stable outpatients with lung cancer who completed the instruments on the first day of the study and two weeks later. Results: The test-retest reproducibility using the intraclass correlation coefficient for the EORTC QLQ-C30 and the QLQ-LC13 ranged from 0.64 to 1.00 and from 0.64 to 0.95, respectively. No correlations were found between the domains of the instruments and clinical parameters. Conclusions: Our findings show that these instruments were reproducible in this sample of patients with lung cancer in Brazil.

Abstract PDF PT PDF EN Portuguese Text

Objective: Patients with lung cancer experience different feelings and reactions, based on their family, social, cultural, and religious backgrounds, which are a source of great distress, not only for the patients but also for their family caregivers. This study aimed to evaluate the impact that lung cancer stage and quality of life (QoL) of lung cancer patients have on caregiver burden. Methods: This was a prospective cross-sectional study. Consecutive patient-caregiver dyads were selected and asked to complete the Hospital Anxiety and Depression Scale and the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). Family caregivers also completed the Caregiver Burden Scale. Group-based modeling was used in order to identify patients with early- or advanced-stage cancer (IA to IIIA vs. IIIB to IV) plus non-impaired or impaired QoL (SF-36 total score > 50 vs. ≤ 50). Patient-caregiver dyads were stratified into four groups: early-stage cancer+non-impaired QoL; advanced-stage cancer+non-impaired QoL; early-stage cancer+impaired QoL; and advanced-stage cancer+impaired QoL. Results: We included 91 patient-caregiver dyads. The majority of the patients were male and heavy smokers. Family caregivers were younger and predominantly female. The burden, QoL, level of anxiety, and level of depression of caregivers were more affected by the QoL of the patients than by their lung cancer stage. The family caregivers of the patients with impaired QoL showed a higher median burden than did those of the patients with non-impaired QoL, regardless of disease stage. Conclusions: Caregiver burden is more affected by patient QoL than by lung cancer stage.

Abstract PDF PT PDF EN Portuguese Text

Objective: To determine the demographic and clinical characteristics of patients with non-small cell lung cancer (NSCLC), as well as their disease course, by age group and gender. Methods: This was a retrospective cohort study of patients diagnosed with NSCLC from 2000 to 2012 and followed until July 2015 in a tertiary referral hospital in the city of São Paulo, Brazil. Based on the 25th and 75th percentiles of the age distribution, patients were stratified into three age groups: < 55 years; ≥ 55 and < 72 years; and ≥ 72 years. Survival time was evaluated during the follow-up period of the study. Functions of overall and gender-specific survival stratified by age groups (event: all-cause mortality) were calculated using the Kaplan-Meier method. Differences among survival curves were assessed via the log-rank test. Results: We included 790 patients with the following age distribution: < 55 years, 165 patients; ≥ 55 and < 72 years, 423; and ≥ 72 years, 202. In the entire sample, there were 493 men (62.4%). Adenocarcinoma was the most common histological pattern in the < 72-year age groups; 575 patients (73%) presented with advanced disease (stages IIIB-IV). The median 5-year survival was 12 months (95% CI: 4-46 months), with no significant differences among the age groups studied. Conclusions: NSCLC remains more common in men, although we found an increase in the proportion of the disease in women in the < 55-year age group. Adenocarcinoma predominated in women. In men, squamous cell carcinoma predominated in the ≥ 72-year age group. Most patients presented with advanced-stage disease at diagnosis. There were no statistical differences in survival between genders or among age groups.

Abstract PDF PT PDF EN Portuguese Text

Objective: To cross-culturally adapt the Wisconsin Smoking Withdrawal Scale (WSWS) for use in Brazil and evaluate the reproducibility of the new (Brazilian Portuguese-language) version. Methods: The original English version of the WSWS was translated into Brazilian Portuguese. For cross-cultural adaptation, the Brazilian Portuguese-language version of the WSWS was administered to eight volunteers, all of whom were smokers. After adjustments had been made, the WSWS version was back-translated into English. The Brazilian Portuguese-language version was thereby found to be accurate. The final Brazilian Portuguese-language version of the WSWS was applied to 75 smokers at three distinct times. For the assessment of interobserver reproducibility, it was applied twice within a 30-min interval by two different interviewers. For the assessment of intraobserver reproducibility, it was applied again 15 days later by one of the interviewers. Intraclass correlation coefficients (ICCs) were used in order to test the concordance of the answers. The significance level was set at p < 0.05. Results: Of the 75 volunteers, 43 (57.3%) were female. The overall mean age was 46.3 years. Interobserver and intraobserver reproducibility was determined for each of the WSWS seven domains, the ICCs for which ranged from 0.87 to 0.94 and from 0.76 to 0.92, respectively. The mean time to completion of the WSWS was 6 min and 44 s, and the response time per question ranged from 4.2 to 12.6 s. Conclusions: The Brazilian Portuguese-language version of the WSWS is reproducible, fast, and simple. It can therefore be used as a tool for assessing the severity of the symptoms of nicotine withdrawal syndrome.
