The pharmacological management of asthma has changed considerably in recent decades, as it has come to be understood that it is a complex, heterogeneous disease with different phenotypes and endotypes. It is now clear that the goal of asthma treatment should be to achieve and maintain control of the disease, as well as to minimize the risks (of exacerbations, disease instability, accelerated loss of lung function, and adverse treatment effects). That requires an approach that is personalized in terms of the pharmacological treatment, patient education, written action plan, training in correct inhaler use, and review of the inhaler technique at each office visit. A panel of 22 pulmonologists was invited to perform a critical review of recent evidence of pharmacological treatment of asthma and to prepare this set of recommendations, a treatment guide tailored to use in Brazil. The topics or questions related to the most significant changes in concepts, and consequently in the management of asthma in clinical practice, were chosen by a panel of experts. To formulate these recommendations, we asked each expert to perform a critical review of a topic or to respond to a question, on the basis of evidence in the literature. In a second phase, three experts discussed and structured all texts submitted by the others. That was followed by a third phase, in which all of the experts reviewed and discussed each recommendation. These recommendations, which are intended for physicians involved in the treatment of asthma, apply to asthma patients of all ages.
Objective: This study aimed to evaluate the prevalence of developmental defects of enamel (DDEs) in relation to asthma severity, symptom onset and pharmacological treatment in pediatric asthma patients. Methods: Children and adolescents (68 asthma patients and 68 controls), 5-15 years of age and residents of the city of Londrina, Brazil, were enrolled in the study. Medical and dental histories were collected through the use of a structured questionnaire. Each participant underwent a dental examination in which the examiner employed the DDE index. Results: Of the 68 asthma group subjects, 61 (89.7%) presented dental enamel defects, compared with only 26 (38.2%) of those in the control group. Using multivariate logistic regression analysis, we estimated the risk of DDEs in permanent dentition to be 11 times higher in pediatric subjects with asthma than in those without (OR = 11.88, p = 0.0001). The occurrence of dental enamel defects correlated with greater asthma severity (p = 0.0001) and earlier symptom onset (p = 0.0001). However, dental enamel defects did not correlate with the initiation of treatment (p = 0.08) or the frequency of medication use (p = 0.93). Conclusions: Pediatric patients with severe, early-onset asthma are at increased risk of dental enamel defects and therefore require priority dental care.Keywords: Asthma/prevention & control; Bronchodilator agents; Adrenal cortex hormones/therapeutic use; Dental enamel; Amelogenesis. ResumoObjetivo: Avaliou-se a prevalência de developmental defects of enamel (DDEs, defeitos de desenvolvimento do esmalte dentário) em pacientes pediátricos com asma e sua relação com a severidade da asma, o início dos sintomas e o tratamento medicamentoso. Métodos: Os participantes do estudo eram residentes do município de Londrina (PR), com 5 a 15 anos, sendo 68 asmáticos e 68 controles. Foram levantados dados retrospectivos da história médica e de saúde bucal da população do estudo através de um questionário estruturado. Todos os participantes foram submetidos a um exame dental. Para a avaliação dos defeitos de desenvolvimento do esmalte dentário, utilizou-se o Índice DDE. Resultados: Neste estudo, foi observado que 61 (89,7%) dos 68 pacientes asmáticos apresentavam defeitos de desenvolvimento do esmalte dentário quando comparado à ocorrência em 26 (38,2%) dos no grupo controle. Através da análise multivariada por regressão logística, foi observado que um paciente pediátrico com asma apresenta risco aumentado em 11 vezes para o aparecimento de defeitos de desenvolvimento do esmalte em dentes permanentes (OR = 11,88, p = 0,0001). Além disso, foi observado uma associação entre defeitos do esmalte dentário e maior severidade da asma (p = 0,0001) e início dos sintomas mais precoce (p = 0,0001). Não se observou associação entre o início do tratamento (p = 0,08) ou frequência de uso da medicação (p = 0,93) com o aparecimento de defeitos de desenvolvimento do esmalte dentário. Conclusões: Pacientes pediátricos com asma apresentam risco aumentado para a ocorrência de defei...
Although asthma can cause reduction in flow rate, the illness did not seem to influence dental caries experience in children with access to proper dental care.
This study evaluated the caries risk of asthmatic patients on the basis of mutans streptococci (MS) and lactobacilli levels in saliva samples as well as the index of oral hygiene and dental caries (DMFT index). The study population was composed of 80 asthmatic children, aged 3–15 years, who use specific medication, and 80 matched, healthy control children. The parents were interviewed about oral health-related factors. The World Health Organization criteria were used for dental examinations. The Köhler and Bratthal methodology was used to detect salivary MS levels and dilutions of saliva were done for lactobacilli counting. No differences between asthma and control groups were observed for caries prevalence in children aged 3–6 and 7–10 years, except in severe cases in the younger group. However, higher caries prevalence for permanent dentition was observed in 11- to 15-year-old asthmatic children. An increased dental biofilm was observed in the asthma group, as well as salivary levels of MS. No differences were observed in levels of lactobacilli. No statistical correlations were found between medication, frequency of treatment, method of consumption and caries experience, dental biofilm and salivary levels of MS or lactobacilli. However, there was a correlation between MS levels and treatment duration. The logistic regression revealed that MS level is an important risk factor for increased caries experience. Asthma should be evaluated as a risk factor for caries experience because it can increase the levels of MS and the dental biofilm.
O Estado do Paraná apresenta grande variabilidade climática por estar situado numa área de transição entre regimes de clima tropical e temperado. O objetivo do trabalho foi definir e analisar algumas variáveis pluviométricas mais significativas em termos ambientais para utilizá-las na composição de zonas pluviométricas homogêneas. Foram utilizados dados pluviométricos de 469 postos meteorológicos, obtidos num período de 30 anos. Os dados foram submetidos às análises de Componentes Principais e de Agrupamento. Concluiu-se que as precipitações de inverno e verão foram importantes para o agrupamento de zonas. Onde há menor pluviometria, há maior diferença entre os trimestres de verão e também nos de inverno e a precipitação de verão é mais concentrada. Nas áreas de maior pluviometria, no sudoeste do Estado, ocorrem as mais elevadas precipitações de inverno e no litoral do Paraná, as chuvas de verão assumem um maior peso na precipitação total anual. Há uma zona intermediária, no centro do Estado, que constitui uma zona de transição, onde os grupos ficaram mais dispersos.
Objective: To report the results of a workshop regarding asthma management programs and centers (AMPCs) in Brazil, so that they can be used as a tool for the improvement and advancement of current and future AMPCs. Methods: The workshop consisted of five presentations and the corresponding group discussions. The working groups discussed the following themes: implementation of asthma management strategies; human resources needed for AMPCs; financial resources needed for AMPCs; and operational maintenance of AMPCs. Results: The workshop involved 39 participants, from all regions of the country, representing associations of asthma patients (n = 3), universities (n = 7), and AMPCs (n = 29). We found a direct relationship between a lack of planning and the failure of AMPCs. Based on the experiences reported during the workshop, the common assumptions about AMPCs in Brazil were the importance of raising awareness of managers; greater community participation; interdependence between primary care and specialized care; awareness of regionalization; and use of medications available in the public health system. Conclusions: Brazil already has a core of experience in the area of asthma management programs. The implementation of strategies for the management of chronic respiratory disease and their incorporation into health care system protocols would seem to be a natural progression. However, there is minimal experience in this area. Joint efforts by individuals with expertise in AMPCs could promote the implementation of asthma management strategies, thus speeding the creation of treatment networks, which might have a multiplier effect, precluding the need for isolated centers to start from zero.
