Objective: To evaluate the correlation between perception of dyspnea during a mild to moderate asthma attack using the Modified Borg Scale (MBS) and peak expiratory flow rate (PEFR).Methods: This was a cross-sectional study conducted with children and adolescents who sought a pediatric emergency service due to an asthma attack. Data were collected from July 2005 to June 2006. Demographic data were recorded. Patients and those in charge of them were requested to grade, individually, the patient's dyspnea using the MBS; afterwards, the PEFR was measured.Results: 181 asthmatic patients were evaluated, with a mean age of 7.2 (± 2.4) years (range, 4-12). The mother sought medical aid in 83.4% of the cases (151/181). Patient symptoms included coughing in 68.5% (124/181), dyspnea in 47.0% (85/181), and wheezing in 12.7% (23/181). Thirty-six percent (65/181) had a mild attack, and 64.1% (116/181) a moderate one. A significant negative correlation was found between the patients' and accompanying adults' perceptions of patient's dyspnea and the PEFR (% predicted; r s = -0.240 and r s = -0.385, respectively).
Conclusion:Both the patients and those looking after them had a poor perception of the severity of the patient's dyspnea. This emphasizes the need to monitor objective measures such as the PEFR and to develop better ways of evaluating dyspnea.J Pediatr (Rio J). 2011;87(6):541-6: Perception, asthma and dyspnea.
ResumoObjetivo: Avaliar a correlação entre a percepção da dispneia durante uma crise de asma leve a moderada, por meio da escala modificada de Borg, com a medida do pico de fluxo expiratório (PFE).
Métodos
IntroduçãoA percepção pode ser definida como sensação consciente de um problema fisiológico apreciada pelo paciente. É o resultado final de uma série de processos: ativação de terminações aferentes por estímulos fisiopatológicos, transmissão e processamento de informações pelas vias neuronais, interpretação no córtex cerebral e reconhecimento pelo paciente.
Clinical and radiological diagnosis in TB cases were valuable and it is important to consider the disease as an adverse event in patients with rheumatic diseases, regardless of the drugs in use.
This prospective study describes the use of Gene-Xpert Ultra for the diagnosis of extrapulmonary tuberculosis (EPTB) in children and adolescents, in Rio de Janeiro, Brazil. Eighteen patients were studied; the final diagnosis of EPTB was established in 13 (72%). Gene-Xpert Ultra results showed detection in 10/13 (77%) of EPTB cases (7 of these 10 with trace-positive results). Gene-Xpert Ultra proved to be a promising method for the diagnosis of childhood EPTB.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
