The prevalence of childhood asthma has increased recently. The aim of this study was to assess the epidemiology of asthma and risk factors for hospital admission among children attending the outpatient and emergency clinic in a university hospital in Sohag, Egypt. The prevalence of asthma over a 6-month period among children aged 3-12 years at this hospital was 1.4% (178/12 612). All the asthmatic children were enrolled in an observational, prospective questionnaire study. More of the asthmatics were males, living in rural areas, with recurrent upper respiratory tract infections, passive exposure to tobacco smoke and suffering attacks at night time; 38 children (21.3%) needed hospital admission for asthma. In multivariate regression analysis, significant risk factors for hospital admission were: both cough and dyspnoea as presenting symptoms; using prophylactic therapy; and complaining of continuous symptoms (during both day and night). Proper use of prophylactic therapies is recommended for better outcomes in our asthmatic children.

Background: Bronchial Asthma is one of the important chronic disease in children. This disease can affect the children mentally and physically in various aspects. Health related quality of life (HRQoL) has become an increasing important issue in the management of Asthma and it is how often used to evaluate the effectiveness of antiasthma drugs. The objectives of the study are to assess the health-related quality of life in Pediatric patients by using Pediatric Asthma quality of life questionnaire and also to assess the impact of parent education in health-related quality life of Asthma patient. The other intention of the study is to determine the anti-asthma drugs utilisation pattern in Pediatric patients.Methods: This study was conducted in in-patient and out-patient department of tertiary care Hospital for a period of 1 year. 145 pediatric patients were participated in this study. A comparative study was conducted to describe the HRQoL in asthma and the pediatric asthma quality of life questionnaire is used to determine the HRQoL of the subjects. Statistical analysis was performed using the instant prism ANOVA test and the Bartlett’s test. P <0.05 was considered statistically significant.Results: This study shows that asthma is more common in male compared to female and most common type was Mild Persistent (47.85). Most of the patient are treated with bronchodilator (71%) followed by steroid (49%) and Leukotrien Antagonist (30.43%). Also revealed that most of the patients are taking multiple drug therapy compared to mono therapy. Quality of life having significant difference in all domains by comparing first visits score. Those suffering from the intermittent type of asthma showed higher mean quality of life score in all domains by comparing first visit score vs second visit score vs third visit score.Conclusions: The health-related quality of life having improvement in all domain and overall quality of life by comparing the initial visit to the follow up visits. The patient education plays major role in improving the quality of life of pediatric population and the quality of life score having relationship with gender, age educational status, severity of asthma and the drug utilization improving health related quality of life.

“…[1][2][3][4][5][6][7][8][9] The underlying mechanisms for this autumnal epidemic of asthma morbidity are thought to include some combination of infectious, allergic, environmental, and climatic stimuli. 2,3 More specifically, environmental allergens, viral respiratory infections, exercise, environmental pollutants, tobacco smoke, and emotional stress may contribute to asthma exacerbations.…”

WHAT'S KNOWN ON THIS SUBJECT: Asthma is a clinical condition treated mostly at primary care community clinics. Epidemics of asthma exacerbation occur annually with return to school after summer vacation and have been reported in many countries, including Israel. WHAT THIS STUDY ADDS:In 82 234 asthmatic children, unscheduled primary care physician visits and drug prescriptions for asthma exacerbations peaked in September after a summer trough, with a lesser peak in late autumn and fluctuations through the winter months. abstract OBJECTIVES: Seasonal variations in asthma are widely recognized, with the highest incidence during September. This retrospective population study aimed to investigate whether this holds true in a large group of asthmatic children in primary care and to assess the impact of age, gender, urban/rural living, and population sector. METHODS:The key study outcomes were the diagnosis of asthma exacerbations and asthma medication prescriptions, recorded by family physicians during 2005 to 2009. These were analyzed by "week of diagnosis" in Clalit Health Services' electronic medical record database. Regression models were built to assess relative strength of secular trends, seasonality, and age-group in explaining the incidence of asthma exacerbations. RESULTS:A total of 919 873 children aged 2 to 15 years were identified. Of these, 82 234 (8.9%) were asthmatic, 61.6% boys and 38.4% girls; 49.1% aged 2 to 5 years, 24.1% 6 to 9 years, and 26.8% 10 to 15 years. We observed a 2.01-fold increase in pediatric asthma exacerbations and 2.28-fold increase in prescriptions of asthma bronchodilator medications during September (weeks 37-39 vs weeks 34-36) compared with August. The association between the opening of school and the incidence of asthma-related visits to the primary care physician was greatest in children aged 2 to 5 years (odds ratio, 2.15) and 6 to 11 years (1.90-fold). Adolescents (age 12-15 years) had a lesser peak (1.81-fold). In late fall there was a second rise, lasting with fluctuations throughout winter, with a trough in summer.CONCLUSIONS: Returning to school after summer is strongly associated with an increased risk for asthma exacerbations and unscheduled visits to the primary care physician.
