The aim of this study was to evaluate the impact of a written asthma action plan (WAAP) on reducing unscheduled doctor visits, asthma control and quality of life in children with all severities of asthma. This was a randomised controlled, single-blinded study whereby 80 children with asthma were randomly assigned to be either provided a WAAP or verbally counseled . The number of asthmatic exacerbations requiring unscheduled doctor visits, asthma control and quality of life were monitored over 9 mo. At the end of the study, there was no significant difference in the number of unscheduled doctor visits between the 2 groups (p = 0.352). There was no significant difference in asthma control or quality of life between both groups. Hence, the WAAP did not reduce unscheduled doctor visits, nor improve asthma control or quality of life in children with all severities of asthma.
Children with uncontrolled asthma have high risk of poor health outcomes. The aim of this study was to assess asthma control and care in primary school children with reported asthma. A total of 6441 primary school children were first screened for parent-reported physician-diagnosed asthma and 448 (8.9%) children were reported to have asthma. Of these, 311 (69.4%) parents
agreed to participate in assessment of asthma control study using Global Initiative for Asthma
2009 guidelines. Only 161 (51.8%) children were found to have good asthma control, 99 (31.8%) had partly controlled asthma, and 51 (16.4%) had uncontrolled asthma in the past one week. In the past 1 year, 157 (50.5%) children had asthma exacerbations, 21 (6.8%) had hospitalizations, and 104 (33.4%) had received emergency asthma care. Only 108 (34.7%) asthmatic children received regular follow-up care. Controller medications were underutilized (12.2%) compared to reliever medications (35.0%). Asthma control among primary school children was poor indicating suboptimal care.

Children with poor asthma control have poor health outcomes. In Malaysia, the Malays have the highest asthma prevalence and poorest control compared to other ethnicities. We aimed to explore Malay children with asthma and their parents' perceptions on asthma and its control. We conducted focus group discussions (FGD) using a semi-structured interview guide. Interviews were audio-recorded, transcribed verbatim and analysed thematically. Sixteen children and parents (N = 32) participated. The perception of asthma was based on personal experience, cultural and religious beliefs, and there was mismatch between children and parents. Parents perceived mild symptoms as normal, some had poor practices, raising safety concerns as children were dependent on them for self-management. Conflicting religious opinions on inhaler use during Ramadhan caused confusion in practice. Parents perceived a lack of system support towards asthma care and asthma affected quality of life. Urgent intervention is needed to address misconceptions to improve asthma care in children.
The increasing prevalence of allergic disease has been linked to reduced microbial exposure in early life. Probiotics have recently been advocated for the prevention and treatment of allergic disease. This article summarises recent publications on probiotics in allergic disease, focusing on clinical studies of prevention or treatment of allergic disease. Studies employing the combined administration of pre-natal and post-natal probiotics suggest a role for certain probiotics (alone or with prebiotics) in the prevention of eczema in early childhood, with the pre-natal component of treatment appearing to be important for beneficial effects. On the other hand, current data are insufficient to support the use of probiotics for the treatment of established allergic disease, although recent studies have highlighted new hope in this area. Probiotic bacteria continue to represent the most promising intervention for primary prevention of allergic disease, and well-designed definitive intervention studies should now be a research priority.
Seventy patients presented with acute asthma at the emergency department of the University of Malaya Medical Centre, Kuala Lumpur were recruited over a two-week period in July 2001. Fifty-one (73%) patients belonged to the poorly controlled group. Fifty-seven (81%) patients were using inhaled salbutamol but 21 (30%) were still using oral short acting salbutamol. Only 32 (46%) patients used inhaled corticosteroids. In the poorly controlled group, 22 (43.1%) patients were not on regular inhaled corticosteroids, 35 (68.6%) were not receiving "add-on" medication and 18 (35%) did not have regular follow up. The emergency department should implement a protocol for asthma management and follow up to achieve better long term patient care.
Asthma is associated with increased pulmonary inflammation and airway hyperresponsiveness. The current use of corticosteroids in the management of asthma has recently raised issues regarding safety and lack of responsiveness in 5-10% of asthmatic individuals. The aim of the present study was to investigate the therapeutic effect of a non-steroidal small molecule that has cysteinyl leukotriene (cysLT) inhibitory activity, upon attenuation of allergic lung inflammation in an acute murine model. Mice were sensitized with ovalbumin (OVA) and treated with several intraperitoneal doses (100, 20, 2 and 0.2mg/kg) of 2,4,6,-trihydroxy-3-geranylacetophenone (tHGA). Bronchoalveolar lavage was performed, blood and lung samples were obtained and respiratory function was measured. OVA sensitization increased pulmonary inflammation and pulmonary allergic inflammation was significantly reduced at doses of 100, 20 and 2mg/kg with no effect at the lowest dose of 0.2mg/kg. The beneficial effects in the lung were associated with reduced eosinophilic infiltration and reduced secretion of Th2 cytokines and cysLTs. Peripheral blood reduction of total IgE was also a prominent feature. Treatment with tHGA significantly attenuated altered airway hyperresponsiveness as measured by the enhanced pause (Penh) response to incremental doses of methacholine. These data demonstrate that tHGA, a synthetic non-steroidal small molecule, can prevent acute allergic inflammation. This proof of concept opens further avenues of research and development of tHGA as an additional option to the current armamentarium of anti-asthma therapeutics.
OBJECTIVE: Written action plans are regarded as an important part of asthma self-management education and yet they may not be understood by those with limited literacy skills. This study was designed to produce an understandable pictorial asthma action plan.
METHODS: With advice from a group of doctors and nurses a "standard" written action plan was translated by a medical artist into a series of pictorial images. These were assessed using the techniques of guessability and translucency by a series of adults attending a specialist asthma clinic in London and the same process was subsequently used to assess comprehensibility of the images and plans amongst a group of Somalis living in Manchester, UK and Malaysians in Seremban, Malaysia.
RESULTS: Guessability testing showed that the majority of pictograms were well understood by each of the study groups. Translucency testing revealed close agreement with intended meaning for the majority of the images. One image, depicting extra use of reliever medication scored less well in all populations; two other images scored less well in the Somali and Malaysian groups and reflect less use of certain inhaler devices in other countries. The overall plan was well understood by all patients who were able to adequately recount the appropriate actions to take in different clinical scenarios.
CONCLUSION: We have developed a pictorial asthma action plan understandable by 3 different populations of patients with asthma.
PRACTICE IMPLICATIONS: Pictorial representations have been shown by other studies in other situations to be an effective method of reinforcing the spoken word. The pictorial asthma action plan developed for this study has been shown to be comprehensible, personalised to the individual in the usual fashion. It is now suitable for further evaluation in clinical practice.
