Objective: To determine whether simple diagnostic methods can yield relevant disease information in patients with rheumatoid arthritis (RA). Methods: Patients with RA were randomly selected for inclusion in a cross-sectional study involving clinical evaluation of pulmonary function, including pulse oximetry (determination of SpO2, at rest), chest X-ray, and spirometry. Results: A total of 246 RA patients underwent complete assessments. Half of the patients in our sample reported a history of smoking. Spirometry was abnormal in 30% of the patients; the chest X-ray was abnormal in 45%; and the SpO2 was abnormal in 13%. Normal chest X-ray, spirometry, and SpO2 were observed simultaneously in only 41% of the RA patients. A history of smoking was associated with abnormal spirometry findings, including evidence of obstructive or restrictive lung disease, and with abnormal chest X-ray findings, as well as with an interstitial pattern on the chest X-ray. Comparing the patients in whom all test results were normal (n = 101) with those in whom abnormal test results were obtained (n = 145), we found a statistically significant difference between the two groups, in terms of age and smoking status. Notably, there were signs of airway disease in nearly half of the patients with minimal or no history of tobacco smoke exposure. Conclusions: Pulmonary involvement in RA can be identified through the use of a combination of diagnostic methods that are simple, safe, and inexpensive. Our results lead us to suggest that RA patients with signs of lung involvement should be screened for lung abnormalities, even if presenting with no respiratory symptoms.

Objective: To present official longitudinal data on the impact of asthma in Brazil between 2008 and 2013. Methods: This was a descriptive study of data collected between 2008 and 2013 from an official Brazilian national database, including data on asthma-related number of hospitalizations, mortality, and hospitalization costs. A geographical subanalysis was also performed. Results: In 2013, 2,047 people died from asthma in Brazil (5 deaths/day), with more than 120,000 asthma-related hospitalizations. During the whole study period, the absolute number of asthma-related deaths and of hospitalizations decreased by 10% and 36%, respectively. However, the in-hospital mortality rate increased by approximately 25% in that period. The geographic subanalysis showed that the northern/northeastern and southeastern regions had the highest asthma-related hospitalization and in-hospital mortality rates, respectively. An analysis of the states representative of the regions of Brazil revealed discrepancies between the numbers of asthma-related hospitalizations and asthma-related in-hospital mortality rates. During the study period, the cost of asthma-related hospitalizations to the public health care system was US$ 170 million. Conclusions: Although the numbers of asthma-related deaths and hospital admissions in Brazil have been decreasing since 2009, the absolute numbers are still high, resulting in elevated direct and indirect costs for the society. This shows the relevance of the burden of asthma in middle-income countries.

Objective: To describe the frequency of popular myths about and features of asthma treatment in children and adolescents in an urban area in southern Brazil. Methods: The parents or legal guardians of public school students (8-16 years of age) completed a specific questionnaire regarding their understanding of asthma, asthma control, and treatment characteristics. The sample included parents or legal guardians of students with asthma (n = 127) and healthy controls (n = 124). Results: The study involved 251 parents or legal guardians, of whom 127 (68.5%) were the mothers and 130 (51.8%) were White. The mean age of these participants was 38.47 ± 12.07 years. Of the participants in the asthma and control groups, 37 (29.1%) and 26 (21.0%), respectively, reported being afraid of using asthma medications, whereas 61 (48%) and 56 (45.2%), respectively, believed that using a metered dose inhaler can lead to drug dependence. However, only 17 (13.4%) and 17 (13.7%) of the participants in the asthma and control groups, respectively, reported being afraid of using oral corticosteroids. In the asthma group, 55 students (43.3%) were diagnosed with uncontrolled asthma, only 41 (32.3%) had a prescription or written treatment plan, and 38 (29.9%) used asthma medications regularly. Conclusions: Popular myths about asthma treatment were common in our sample, as were uncontrolled asthma and inappropriate asthma management. Further studies in this field should be conducted in other developing countries, as should evaluations of pediatric asthma treatment programs in public health systems.
