The main components of A. membranaceus were identified by HPLC. The children with asthma remission were divided into two combination group(control group, the combination of budesonide and terbutaline) and A. membranaceus group(treatment group, the combination of budesonide, terbutaline and A. membranaceus). The therapeutic results were compared between two groups after 3-month therapy.Porcine peripheral blood mononuclear cells(PBMCs) were isolated from venous blood by using density gradient centrifugation on percoll. The levels of Fox P3, EGF-β, IL-17 and IL-23 from PBMCs and serum Ig E were measured. The relative percentage of Treg/Th17 cells was determined using flow cytometry. The main components of A. membranaceus were calycosin-7-O-glucoside, isoquercitrin, ononin, calycosin, quercetin, genistein, kaempferol, isorhamnetin and formononetin, all of which may contribute to asthma therapy. Lung function was significantly improved in the treatment group when compared with a control group(P < 0.05). The efficacy in preventing the occurrence of childhood asthma was higher in the treatment group than the control group(P < 0.05).The levels of Ig E, IL-17 and IL-23 were reduced significantly in the treatment group when compared with the control group, while the levels of FoxP3 and TGF-β were increased in the treatment group when compared with the control group(P < 0.05). A. membranaceus increased the percentage of Treg cells and reduced the percentage of Th17 cells. A. membranaceus is potential natural product for improving the therapeutic efficacy of combination therapy of budesonide and terbutaline for the children with asthma remission by modulating the balance of Treg/Th17 cells.展开更多

The burden of asthma is disproportionate with ruralUSpopulations experiencing a higher prevalence of the disease. Rural populations experience additional disparities regarding health care access, job availability, and daily living resources. Hence, the family impact of having a child with asthma may be influenced by geographic locale. This impact could be a result of health insurance tied to employment, out of pocket costs, and health care provider availability. Few studies have assessed the impact a child’s asthma has on a family. This study sought to answer the question: What is the impact of children with asthma on US rural families? Methods: Multivariate techniques were performed to examine a single year of data from two connected population-based datasets, the 2007-2008 National Survey of Children’s Health and the 2009-2010 Children with Special Health Care Needs Survey. Children with current asthma defined the study population for both datasets. A logistic regression model was performed for each database. The dependent variable for the first model was child in family currently has asthma, for the second it was rural children with current asthma. Results: The first logistic regression model confirmed that rural children were more likely to have asthma than non-rural children. The second logistic regression model yielded that rural families with a child diagnosed with asthma had greater odds of: not having health insurance, having a parent who stopped working, avoided a job change, or experienced financial problems because of the child’s health. Conclusions: This study demonstrated that rural families experience a disproportionate financial hardship as a result of their child’s asthma. Pharmacist intervention in asthma care in rural areas has the potential to decrease the financial burden for a family while also improving a child’s health.展开更多

Methods: This is a school-based cross-sectional study conducted from January to February 2016. A random sample of 544 children aged 12 - 15 years were enrolled from five private schools of Karachi. Dental caries was assessed using DMFT Index (Decayed, Missing, Filled teeth). The main exposure variable was asthma and information on it was collected through the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Results: The data was analyzed using Cox Proportional Hazard algorithm. Crude and adjusted prevalence ratios with 95% CI were reported. Total 554 children, 306 (56.3%) boys and 43.7% girls participated in the study. Mean age of children was 13.2 ± 0.05 years. Total number of children with DMFT > 0 was 30.5%. The decayed component contributed largely (22.8%) to the DMFT score. Overall prevalence of asthma was 20%. Prevalence of caries in asthmatic children was 28.4% as compared to 31% among non-asthmatic children. Adjusted prevalence ratio of dental caries in asthmatic children was 0.8 (95% CI 0.6 - 1.3) after adjusting for carious food intake, age, oral hygiene index and dentist visit;the association between asthma and dental caries turned out to be in-significant. Conclusions: There was no association observed between asthma and dental caries among the children examined in this study.展开更多

Patients and methods: We reviewed the records of children hospitalized in the Pediatric Intensive Care Unit of University Hospital of Brazzaville from January 1 to December 31, 2015, and retained those from two months to 17 years hospitalized for asthma. The study variables were: age, sex, influence of seasons, history of atopy;the factors triggering the crisis, the type of follow-up, the degree of severity of asthma exacerbation, the type of treatment instituted and the course of the disease. In total, out of 2012 hospitalized children, 65 children met the inclusion criteria. Results: The hospital prevalence of asthma was 3.5%. Among 65 children of study, 42 (59.2%) were male and 29 (40.8%) female. The mean age was 3.9 ± 2.9 years (range from 2 months to 14 years). Children aged 30 months to 5 years were the most represented (40%). They were known as asthmatics, n = 18 (27.7%). Family atopy was found, n = 11 (16.9%). Acute Otorhinolaryngologic infections were in all cases the factors triggering the crisis. The peak frequency of hospitalizations for asthma occurred during the short rainy season. The crisis was moderate n = 46 (70%) and severe n = 19 (29%). Beta 2 mimetics were administered in all cases, by subcutaneous in 18 cases (27.7%) and inhaled in 47 cases (72.3%). The outcome was favorable in all cases with a mean hospital stay of 1.46 ± 0.92 days. Conclusion: Childhood asthma remains a public health challenge and severe asthma is the paradigm of uncontrolled and costly asthma. This first work suggests that a large-scale study be carried out for a better knowledge of it.展开更多

Methods: 60 stable allergic asthmatic children aged 7 to 16 years on a low to medium dose treatment with inhaled corticosteroids (ICS) were recruited to a double blind randomised controlled trial. At study entry (visit 1), the following was assessed: FeNO, spirometry, bronchial hyper-responsiveness to mannitol (MDP-?test), quality of life (paediatric asthma quality-of-life questionnaire;PAQLQ) and asthma control (asthma control test;ACT). Subjects were randomly assigned to one of three groups and treatment was modified by a blinded respiratory physician according to the test results of visit 1: ICS dose was doubled when FeNO was >22 ppb (group 1), in case of a positive MDP-test (group 2) or when FEV1 was <80% of a predicted one (group 3), respectively, or remained unchanged for the remaining subjects. After 3 months (visit 2), the subjects were reassessed and all tests were repeated. Results: 48 children successfully completed the study. At the first visit, 8 out of 16 (50%) children in group 1 showed a FeNO > 22 ppb, 8 children out of 16 (50%) in group 2 showed a positive MDP-test and 3 children out of 16 (18.7%) in group 3 had a FEV1 < 80% of that predicted and had their ICS-dose doubled. In group 1, FeNO decreased significantly after the intervention (p = 0.005), whereas the self-administered and the interviewer-administered PAQLQ (p = 0.02 resp. p = 0.033) as well as the ACT (p = 0.031) increased. Neither the number of children with a positive mannitol challenge nor spirometric results changed significantly. In group 2 and group 3, there were no significant changes in none of the assessed parameters. Conclusion: In this small pragmatic double blind randomised controlled study, we showed that ICS dose modification based on FeNO led to increased quality of life and enhanced asthma control, and to a reduction in airway inflammation and was superior to treatment modifications based on bronchial hyper-responsiveness to mannitol or on FEV1.展开更多

Asthma exacerbations also demonstrate a seasonal pattern in which high rates can be seen at a particular season and knowledge of the seasonal pattern of asthma exacerbation in any locality can improve asthma management. Objective: To determine the prevalence, management outcome and seasonal pattern of emergency department visits for acute exacerbation of asthma. Methods: This was a retrospective review of the emergency department register of all asthma admissions in the Rivers State University Teaching Hospital, Portharcourt, Nigeria over a five year period from January 2014 to December 2018. Results: A total of 205 (2.9%) asthma-related visits were recorded out of 7046 emergency room visits. The mean age of the patients was 6.1 (±4.2) yrs, with an M:F ratio of 1.97:1. The median length of hospital stay was 24 hrs. Children older than 11 yrs were more likely to be admitted for >48 hrs (OR 4.18, 95% CI;1.67, 10.39, P;0.003). Emergency department visits for asthma were more in the rainy season April-September 129 (63.9%) with a peak in May. There is a significant variation in the seasonal pattern of emergency room asthma admission with age (P = 0.018). Children >3 yrs have their highest admission rates in May while younger children experience two peaks in February and November. Conclusion: Asthma exacerbation is more in rainy season among children in Portharcourt although there is a variation in seasonal pattern of asthma exacerbation with age.展开更多

Bronchial asthma (BA) is one of the common childhood diseases that affects the respiratory system characterized by recurrent cough, wheezing, chest tightness and difficulty with breathing. The two conditions are different manifestations of allergic disease of the airway;the composition of the inflammatory substrate in the mucosa of allergic patients is similar to the late-phase allergic response seen elsewhere in the respiratory tract, such as in bronchial asthma. Aim: The aim was to compare the impacts of allergic rhinitis and bronchial asthma on tympanometric parameters in children. Patients & Methods: This is a hospital based comparative cross-sectional study. Two groups of participants aged 4 - 12 years, one group with documented clinical diagnosis of allergic rhinitis and the other group with documented clinical diagnosis of bronchial asthma were consecutively selected from ear, nose and throat (ENT) and pediatrics cardiopulmonary outpatient clinics of Aminu Kano Teaching Hospital Kano respectively. Equal number of children aged 4 - 12 years with no history of ENT diseases or bronchial asthma that were selected from elementary schools within the same community served as a control group. An interviewer-administered questionnaire was filled out for all the participants, complete ENT and chest examinations were carried out and subsequently all the selected participants had tympanometry done, findings were recorded and analyzed. Results: The mean age of participants with bronchial asthma was found to be 7.5 ± 2.6 years while participants with allergic rhinitis had the mean age of 6.8 ± 2.1 years. The mean middle ear pressure (MEP) of participants with bronchial asthma was found to be -15.22 dapa and -40.32 dapa in those with allergic rhinitis. Acoustic reflex was found to be absent in 15.4% of the participants with bronchial asthma and 29.6% of allergic rhinitis participants. Type B tympanogram was found in 2.8% of bronchial asthma participants and 7.3% in participants with allergic rhinitis. Type C tympanogram was found in 4.6% of participants with bronchial asthma and 15.5% of participants with allergic rhinitis. Type A tympanogram was found in 90% of participants with bronchial asthma and 75% of participants with allergic rhinitis. The difference between type A, B and C tympanograms of participants with bronchial asthma and those with allergic rhinitis was found to be statistically significant (Type A χ<sup>2</sup> = 14.62, df = 4, p value = 0.01, Type B χ<sup>2</sup> = 14.06, df = 4, p value = 0.01, Type C χ<sup>2</sup> = 17.01, df = 6, p value = 0.01). Conclusion: Participants with allergic rhinitis were found to have more abnormalities of tympanometric parameters compared to participants with bronchial asthma which signifies allergic rhinitis conferred an increased risk of having middle ear diseases and otitis media with effusion compared to bronchial asthma.展开更多

The aim of this study is to examine the association between elevated annual mean concentration of PM2.5 (particulate matter with aerodynamic diameter less than 2.5 micrometers) and surface ozone and asthma prevalence among school children in Japan from 2006 to 2009. Annual rates of asthma prevalence among preschool and school children (5 to 11 years) are obtained from the database of the Ministry of Education, Culture, Sports, Science and Technology—Japan (MEXT). Data on the concentrations of PM2.5 and surface ozone were obtained from 1,183 stations of air quality monitoring distributed in 47 prefectures. Annual means of these concentrations were compared to annual variations in asthma prevalence by using Pearson correlation coefficient. We found different associations between the annual mean concentration of PM2.5 and surface ozone and the annual rates of asthma prevalence among preschool and school children from 2006 to 2009. The positive values of the correlation coefficient in prefectures such as, Gumma, Shimane, and Niigata, are consistent with the previous knowledge. However, significant inverse associations were found in many prefectures. Our study suggests that the association between elevated concentrations of PM2.5 and surface ozone and asthma prevalence among school children in Japan is not strong enough to assume concretely a plausible and significant association.展开更多

Methods: 100 children with cough variant asthma admitted from June 2019 to May 2020 were selected as the object of this study combined with the clinical research subjects of children with cough variant asthma, and were simultaneously divided into the control group and the observation group, and the actual records of the observation and textual research of the disease conditions of the related 100 children were well recorded. Among them, the control group mainly adopts the conventional treatment management measures, while the observation group adopts the clinical treatment implementation plan of "salbutamol and phenergan" to further analyze the optimization effect of the two groups of children in clinical treatment. Results: from the change after treatment, the maximum expiratory flow rate in the observation group was (87.8 ± 4.1) L/min;The change of high expiratory flow rate in the control group was (84.0 ± 4.2) L/min, and the comparison between the two groups was statistically significant (P < 0.05). To sum up, the clinical observation of the actual situation of the treatment of the two groups of patients, of which the maximum group's total effective rate of 94% was significantly higher than the control group of 84%;At the same time, the incidence of treatment after three months was observed, among which the incidence of observation of the other side was 96%(48/50)/ that of the control group was 84%(42/50). There were statistically significant differences between the two groups in the comparison of clinical treatment effect and incidence, P < 0.05. Conclusion: The treatment scheme of salbutamol and phenergan is beneficial to the disease control of children with cough variant asthma, which not only improves the therapeutic effect, but also can prevent the recurrence of the disease, and is worthy of further promotion and application.展开更多

Methods: the children with acute exacerbation of bronchial asthma who were treated in our hospital from January 2021 to January 2022 were selected as the research subjects, and the effects of different treatments were compared, including shegan mahuang decoction and acupoint application + shegan mahuang decoction. Results: after the effective treatment plan was implemented, the condition improved, especially the children treated with acupoint application + shegan mahuang decoction had a higher total effective rate, a lower incidence of adverse reactions, a good trend in FVC and other levels, and symptoms and signs. The scores were lower, and the children who received acupoint application treatment were relatively poor, and the difference was significant (P<0.05). Conclusion: in the treatment of acute exacerbation of bronchial asthma in children, shegan mahuang decoction combined with acupoint application has obvious application value and high safety, and plays a positive role in further shortening the course of the disease in children.展开更多

Further, it has been documented that asthma morbidity responds to socioeconomic variations. This study evaluates the relationship between asthma and five air pollutants along with socioeconomic status in Texas counties from 2005 to 2013. Air pollutants investigated were carbon monoxide (CO), nitrogen dioxide (NO<sub>2</sub>), ozone (O<sub>3</sub>), fine particulate matter (PM2.5), and sulfur dioxide (SO<sub>2</sub>). Exploratory and spatial analyses produced consistent results. Asthma prevalence was positively associated with PM2.5, SO<sub>2</sub>, living near a park, and living in an urban area. Asthma childhood prevalence rates were positively associated with living in a household with a female head and negatively associated with ethnicity: Caucasian, Hispanic, and African American. Adult prevalence rates were positively associated with living in a household with female head, being on food stamps, and PM2.5. Both the overall and adult rates were positively associated with poverty. Asthma hospitalizations in Texas were positively associated with aerosol particles, sulfur dioxide, and low income. Moreover, the majority of air pollution in Texas is formed by stationary sources, which contradicts recent claims that mobile sources are the main emitters in Texas. Our findings are consistent with those from other geographical locations and suggest that additional studies and measures are required to fully explain the associations detected and underlying cause and effect paradigm.展开更多

Methods A cross-sectional, population-based survey of prevalence of asthrna was conducted in children aged from 0 to 14 years in 3 major cities of China （Beijing, Chongqing, and Guangzhou） with different geographic locations. All the subjects were randomly selected by a multi-stage sampling method. Three to five schools and kindergartens in 2 urban districts in each city were randomly selected for the survey, and a validated questionnaire that included the core questions of the International Study of Asthma and Allergies in Childhood, Phase III questionnaire and several additional questions were used. All questionnaires were completed by parents or guardians of the selected children. Children whose parents responded affirmatively to the question＂ Has your child ever been diagnosed as asthma by a doctor＂ were recognized as victims of asthma. Results The prevalence of asthma in Beijing, Chongqing, and Guangzhou was 3.15%, 7.45%, and 2.09%, respectively. These values were significantly higher than those obtained 10 years ago in the national epidemiological survey in 2000 which used the same method of investigation and the same diagnotic criteria （x^2=3.938, P=-0.047; 22=73.506, P≤0.001; x^2=11.956, P=0.001, in each city）. Of the asthmatic children 57.21%, 69.91%, and 60.00% had their first attack before the age of 3 in Beijing, Chongqing, and Guangzhou, respectively. Wheezing was the primary clinical manifestation for all asthmatic children, followed by persistent cough and repeated respiratory infections. Both the prevalence of asthma and asthma-related symptoms were statistically higher in males than in females. Conclusion The prevalence of childhood asthma is statistically higher than that 10 years ago in the three Chinese cities.展开更多

With this regard, pediatricians play a key role in the management of these conditions. The closeness with the family, the knowledge of the clinical case and the care continuity allow the pediatrician to acquire a position of director of every case. When pathological events have a chronic feature, suddenly the quality of life of the whole family changes. For this reason the first communication of chronic disease is very important and the task of the pediatrician should be to provide a positive message to help the family in facing the difficulty of this new challenge. The bronchial asthma is the most common chronic disease worldwide. The incidence, the prevalence, and the mortality of the disease have increased in children over the past decades. These trends are particularly marked above all in preschool children. The success reached by Pediatricians is closely related to the compliance and the implementation of the therapy followed by the little patient and his family. With this regard authors, in this review, focus on the illustration of several strategies, based on the pediatrician’ skills and medicine documents, that can be used for the improvement of communication among pedia- trician-family and child, never forgetting the hu- man aspect of the same doctor, that should con- ciliate with the scientific knowledge in the taking care of a specific chronic disease.展开更多

METHOD A cross-sectional study was conducted among 13 to 15-year-old children from six randomly selected schools in Anuradhapura district of Sri Lanka. Data were collected using translated and validated selfadministered questionnaires(Rome Ⅲ questionnaire, International Study on Asthma and Allergies in Childhood questionnaire, and Pediatric Quality of Life Inventory 4.0) and administered under an examination setting after obtaining parental consent and assent.RESULTS Of the 1101 children included in the analysis, 157(14.3%) had asthma and 101(9.2%) had at least one FAPDs. Of children with asthma, 19.1% had at least one type of FAPDs. Prevalence rates of functional abdominal pain(FAP)(8.9% vs 3.3% in nonasthmatics), functional dyspepsia(FD)(2.5% vs 0.7%), and abdominal migraine(AM)(3.2% vs 0.4%) were higher in those with asthma(P < 0.05, multiple logistic regression analysis), but not in those with irritable bowel syndrome(4.5% vs 3.1%, P = 0.2). Severe abdominal pain(10.8% vs 4.6%), bloating(16.6% vs 9.6%), nausea(6.4% vs 2.9%), and anorexia(24.2% vs 16.2%) were more prevalent among asthmatics(P < 0.05). Lower gastrointestinal symptoms did not show a significant difference. Scores obtained for health related quality of life(HRQoL) were lower in those with asthma and FAPDs(P < 0.05, unpaired t-test).CONCLUSION Asthma is associated with three different types of FAPDs, namely, FD, AM, and FAP. HRQoL is significantly impaired in teenagers with asthma and FAPDs.展开更多

文摘Astragalus membranaceus may be a potential therapy for childhood asthma but its driving mechanism remains elusive. The main components of A. membranaceus were identified by HPLC. The children with asthma remission were divided into two combination group(control group, the combination of budesonide and terbutaline) and A. membranaceus group(treatment group, the combination of budesonide, terbutaline and A. membranaceus). The therapeutic results were compared between two groups after 3-month therapy.Porcine peripheral blood mononuclear cells(PBMCs) were isolated from venous blood by using density gradient centrifugation on percoll. The levels of Fox P3, EGF-β, IL-17 and IL-23 from PBMCs and serum Ig E were measured. The relative percentage of Treg/Th17 cells was determined using flow cytometry. The main components of A. membranaceus were calycosin-7-O-glucoside, isoquercitrin, ononin, calycosin, quercetin, genistein, kaempferol, isorhamnetin and formononetin, all of which may contribute to asthma therapy. Lung function was significantly improved in the treatment group when compared with a control group(P < 0.05). The efficacy in preventing the occurrence of childhood asthma was higher in the treatment group than the control group(P < 0.05).The levels of Ig E, IL-17 and IL-23 were reduced significantly in the treatment group when compared with the control group, while the levels of FoxP3 and TGF-β were increased in the treatment group when compared with the control group(P < 0.05). A. membranaceus increased the percentage of Treg cells and reduced the percentage of Th17 cells. A. membranaceus is potential natural product for improving the therapeutic efficacy of combination therapy of budesonide and terbutaline for the children with asthma remission by modulating the balance of Treg/Th17 cells.

文摘Dear Editor,Cumulative evidence supports the role of early-life viral infections,especially respiratory syncytial virus(RSV)and human rhinovirus(HRV),as major antecedents of childhood asthma(Lemanske,2002;Jackson et al.,2008).In this study,the x TAG respiratory viral panel FAST(RVP FAST)assay,a multiplex polymerase chain reaction(PCR)-based method(Arens et al.,2010;BaladaLlasat et al.,2011;Gharabaghi et al.,2011;Selvaraju,2012),was used to investigate the association of infec-
文摘Introduction: Approximately 7.1 million US children have asthma. The burden of asthma is disproportionate with ruralUSpopulations experiencing a higher prevalence of the disease. Rural populations experience additional disparities regarding health care access, job availability, and daily living resources. Hence, the family impact of having a child with asthma may be influenced by geographic locale. This impact could be a result of health insurance tied to employment, out of pocket costs, and health care provider availability. Few studies have assessed the impact a child’s asthma has on a family. This study sought to answer the question: What is the impact of children with asthma on US rural families? Methods: Multivariate techniques were performed to examine a single year of data from two connected population-based datasets, the 2007-2008 National Survey of Children’s Health and the 2009-2010 Children with Special Health Care Needs Survey. Children with current asthma defined the study population for both datasets. A logistic regression model was performed for each database. The dependent variable for the first model was child in family currently has asthma, for the second it was rural children with current asthma. Results: The first logistic regression model confirmed that rural children were more likely to have asthma than non-rural children. The second logistic regression model yielded that rural families with a child diagnosed with asthma had greater odds of: not having health insurance, having a parent who stopped working, avoided a job change, or experienced financial problems because of the child’s health. Conclusions: This study demonstrated that rural families experience a disproportionate financial hardship as a result of their child’s asthma. Pharmacist intervention in asthma care in rural areas has the potential to decrease the financial burden for a family while also improving a child’s health.
文摘Objective: The study aimed to determine an association between dental caries and asthma among 12 to 15 years old children. Methods: This is a school-based cross-sectional study conducted from January to February 2016. A random sample of 544 children aged 12 - 15 years were enrolled from five private schools of Karachi. Dental caries was assessed using DMFT Index (Decayed, Missing, Filled teeth). The main exposure variable was asthma and information on it was collected through the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Results: The data was analyzed using Cox Proportional Hazard algorithm. Crude and adjusted prevalence ratios with 95% CI were reported. Total 554 children, 306 (56.3%) boys and 43.7% girls participated in the study. Mean age of children was 13.2 ± 0.05 years. Total number of children with DMFT > 0 was 30.5%. The decayed component contributed largely (22.8%) to the DMFT score. Overall prevalence of asthma was 20%. Prevalence of caries in asthmatic children was 28.4% as compared to 31% among non-asthmatic children. Adjusted prevalence ratio of dental caries in asthmatic children was 0.8 (95% CI 0.6 - 1.3) after adjusting for carious food intake, age, oral hygiene index and dentist visit;the association between asthma and dental caries turned out to be in-significant. Conclusions: There was no association observed between asthma and dental caries among the children examined in this study.
文摘Objectives: To describe the epidemiological, clinical and therapeutic aspects of asthma in children at the Pediatric Intensive Care Unit of University Hospital of Brazzaville. Patients and methods: We reviewed the records of children hospitalized in the Pediatric Intensive Care Unit of University Hospital of Brazzaville from January 1 to December 31, 2015, and retained those from two months to 17 years hospitalized for asthma. The study variables were: age, sex, influence of seasons, history of atopy;the factors triggering the crisis, the type of follow-up, the degree of severity of asthma exacerbation, the type of treatment instituted and the course of the disease. In total, out of 2012 hospitalized children, 65 children met the inclusion criteria. Results: The hospital prevalence of asthma was 3.5%. Among 65 children of study, 42 (59.2%) were male and 29 (40.8%) female. The mean age was 3.9 ± 2.9 years (range from 2 months to 14 years). Children aged 30 months to 5 years were the most represented (40%). They were known as asthmatics, n = 18 (27.7%). Family atopy was found, n = 11 (16.9%). Acute Otorhinolaryngologic infections were in all cases the factors triggering the crisis. The peak frequency of hospitalizations for asthma occurred during the short rainy season. The crisis was moderate n = 46 (70%) and severe n = 19 (29%). Beta 2 mimetics were administered in all cases, by subcutaneous in 18 cases (27.7%) and inhaled in 47 cases (72.3%). The outcome was favorable in all cases with a mean hospital stay of 1.46 ± 0.92 days. Conclusion: Childhood asthma remains a public health challenge and severe asthma is the paradigm of uncontrolled and costly asthma. This first work suggests that a large-scale study be carried out for a better knowledge of it.

文摘Aim: The goal of this study was to compare asthma treatment guidance based on bronchial hyper-responsiveness to mannitol, spirometry or exhaled nitric oxide (FeNO) in stable asthmatic children. Methods: 60 stable allergic asthmatic children aged 7 to 16 years on a low to medium dose treatment with inhaled corticosteroids (ICS) were recruited to a double blind randomised controlled trial. At study entry (visit 1), the following was assessed: FeNO, spirometry, bronchial hyper-responsiveness to mannitol (MDP-?test), quality of life (paediatric asthma quality-of-life questionnaire;PAQLQ) and asthma control (asthma control test;ACT). Subjects were randomly assigned to one of three groups and treatment was modified by a blinded respiratory physician according to the test results of visit 1: ICS dose was doubled when FeNO was >22 ppb (group 1), in case of a positive MDP-test (group 2) or when FEV1 was <80% of a predicted one (group 3), respectively, or remained unchanged for the remaining subjects. After 3 months (visit 2), the subjects were reassessed and all tests were repeated. Results: 48 children successfully completed the study. At the first visit, 8 out of 16 (50%) children in group 1 showed a FeNO > 22 ppb, 8 children out of 16 (50%) in group 2 showed a positive MDP-test and 3 children out of 16 (18.7%) in group 3 had a FEV1 < 80% of that predicted and had their ICS-dose doubled. In group 1, FeNO decreased significantly after the intervention (p = 0.005), whereas the self-administered and the interviewer-administered PAQLQ (p = 0.02 resp. p = 0.033) as well as the ACT (p = 0.031) increased. Neither the number of children with a positive mannitol challenge nor spirometric results changed significantly. In group 2 and group 3, there were no significant changes in none of the assessed parameters. Conclusion: In this small pragmatic double blind randomised controlled study, we showed that ICS dose modification based on FeNO led to increased quality of life and enhanced asthma control, and to a reduction in airway inflammation and was superior to treatment modifications based on bronchial hyper-responsiveness to mannitol or on FEV1.
文摘Acute exacerbations of asthma are one of the leading causes of emergency room visits and hospitalizations in children. Asthma exacerbations also demonstrate a seasonal pattern in which high rates can be seen at a particular season and knowledge of the seasonal pattern of asthma exacerbation in any locality can improve asthma management. Objective: To determine the prevalence, management outcome and seasonal pattern of emergency department visits for acute exacerbation of asthma. Methods: This was a retrospective review of the emergency department register of all asthma admissions in the Rivers State University Teaching Hospital, Portharcourt, Nigeria over a five year period from January 2014 to December 2018. Results: A total of 205 (2.9%) asthma-related visits were recorded out of 7046 emergency room visits. The mean age of the patients was 6.1 (±4.2) yrs, with an M:F ratio of 1.97:1. The median length of hospital stay was 24 hrs. Children older than 11 yrs were more likely to be admitted for >48 hrs (OR 4.18, 95% CI;1.67, 10.39, P;0.003). Emergency department visits for asthma were more in the rainy season April-September 129 (63.9%) with a peak in May. There is a significant variation in the seasonal pattern of emergency room asthma admission with age (P = 0.018). Children >3 yrs have their highest admission rates in May while younger children experience two peaks in February and November. Conclusion: Asthma exacerbation is more in rainy season among children in Portharcourt although there is a variation in seasonal pattern of asthma exacerbation with age.

文摘Objective:The purpose of this study is to investigate the application of Chinese and Western medicine in the health management of school-age children with asthma and its research progress,with a view to providing a more comprehensive and effective management strategy for the clinic.Methods:Using the method of literature review,this study systematically searched and analyzed the relevant studies on the combination of Chinese and Western medicine in the health management of school-aged children with asthma in recent years,focusing on Chinese medicine treatment,Western medicine treatment,and the combined health management of Chinese and Western medicine.Results:Chinese medicine treatment,Western medicine treatment,and the health management mode of combining Chinese and Western medicine showed unique advantages in school-age asthmatic children.Through the comprehensive use of Chinese medicine’s diagnosis and treatment,Chinese medicine conditioning,Chinese medicine characteristic therapy,and Western medicine’s modern medical methods,it not only effectively relieved asthma symptoms but also significantly improved the quality of life of the children.At the same time,this management mode also focuses on the psychological guidance and family care of the children,forming an all-round and multi-level health management system.Conclusion:The health management strategy of combining Chinese and Western medicine has a broad application prospect in school-age asthmatic children,and its specific interventions and mechanisms of action should be further studied to provide more scientific and systematic guidance for clinical practice.
文摘Background: Allergic rhinitis (AR) is a multifocal IgE-mediated type I hypersensitivity reaction that affects sino-nasal mucosa and is characterized by excessive sneezing, watery rhinorrhea, nasal itching, nasal stuffiness and eyes itching. Bronchial asthma (BA) is one of the common childhood diseases that affects the respiratory system characterized by recurrent cough, wheezing, chest tightness and difficulty with breathing. The two conditions are different manifestations of allergic disease of the airway;the composition of the inflammatory substrate in the mucosa of allergic patients is similar to the late-phase allergic response seen elsewhere in the respiratory tract, such as in bronchial asthma. Aim: The aim was to compare the impacts of allergic rhinitis and bronchial asthma on tympanometric parameters in children. Patients & Methods: This is a hospital based comparative cross-sectional study. Two groups of participants aged 4 - 12 years, one group with documented clinical diagnosis of allergic rhinitis and the other group with documented clinical diagnosis of bronchial asthma were consecutively selected from ear, nose and throat (ENT) and pediatrics cardiopulmonary outpatient clinics of Aminu Kano Teaching Hospital Kano respectively. Equal number of children aged 4 - 12 years with no history of ENT diseases or bronchial asthma that were selected from elementary schools within the same community served as a control group. An interviewer-administered questionnaire was filled out for all the participants, complete ENT and chest examinations were carried out and subsequently all the selected participants had tympanometry done, findings were recorded and analyzed. Results: The mean age of participants with bronchial asthma was found to be 7.5 ± 2.6 years while participants with allergic rhinitis had the mean age of 6.8 ± 2.1 years. The mean middle ear pressure (MEP) of participants with bronchial asthma was found to be -15.22 dapa and -40.32 dapa in those with allergic rhinitis. Acoustic reflex was found to be absent in 15.4% of the participants with bronchial asthma and 29.6% of allergic rhinitis participants. Type B tympanogram was found in 2.8% of bronchial asthma participants and 7.3% in participants with allergic rhinitis. Type C tympanogram was found in 4.6% of participants with bronchial asthma and 15.5% of participants with allergic rhinitis. Type A tympanogram was found in 90% of participants with bronchial asthma and 75% of participants with allergic rhinitis. The difference between type A, B and C tympanograms of participants with bronchial asthma and those with allergic rhinitis was found to be statistically significant (Type A χ<sup>2</sup> = 14.62, df = 4, p value = 0.01, Type B χ<sup>2</sup> = 14.06, df = 4, p value = 0.01, Type C χ<sup>2</sup> = 17.01, df = 6, p value = 0.01). Conclusion: Participants with allergic rhinitis were found to have more abnormalities of tympanometric parameters compared to participants with bronchial asthma which signifies allergic rhinitis conferred an increased risk of having middle ear diseases and otitis media with effusion compared to bronchial asthma.
文摘Researches on asthma have found that air pollution increased asthma prevalence among sensitive age groups, including school children, and exposed them to the recognized health impacts. The aim of this study is to examine the association between elevated annual mean concentration of PM2.5 (particulate matter with aerodynamic diameter less than 2.5 micrometers) and surface ozone and asthma prevalence among school children in Japan from 2006 to 2009. Annual rates of asthma prevalence among preschool and school children (5 to 11 years) are obtained from the database of the Ministry of Education, Culture, Sports, Science and Technology—Japan (MEXT). Data on the concentrations of PM2.5 and surface ozone were obtained from 1,183 stations of air quality monitoring distributed in 47 prefectures. Annual means of these concentrations were compared to annual variations in asthma prevalence by using Pearson correlation coefficient. We found different associations between the annual mean concentration of PM2.5 and surface ozone and the annual rates of asthma prevalence among preschool and school children from 2006 to 2009. The positive values of the correlation coefficient in prefectures such as, Gumma, Shimane, and Niigata, are consistent with the previous knowledge. However, significant inverse associations were found in many prefectures. Our study suggests that the association between elevated concentrations of PM2.5 and surface ozone and asthma prevalence among school children in Japan is not strong enough to assume concretely a plausible and significant association.

文摘Objective: to observe the clinical therapeutic effect of "salbutamol and phenergan" in the implementation of "children with cough variant asthma" through clinical experiments. Methods: 100 children with cough variant asthma admitted from June 2019 to May 2020 were selected as the object of this study combined with the clinical research subjects of children with cough variant asthma, and were simultaneously divided into the control group and the observation group, and the actual records of the observation and textual research of the disease conditions of the related 100 children were well recorded. Among them, the control group mainly adopts the conventional treatment management measures, while the observation group adopts the clinical treatment implementation plan of "salbutamol and phenergan" to further analyze the optimization effect of the two groups of children in clinical treatment. Results: from the change after treatment, the maximum expiratory flow rate in the observation group was (87.8 ± 4.1) L/min;The change of high expiratory flow rate in the control group was (84.0 ± 4.2) L/min, and the comparison between the two groups was statistically significant (P < 0.05). To sum up, the clinical observation of the actual situation of the treatment of the two groups of patients, of which the maximum group's total effective rate of 94% was significantly higher than the control group of 84%;At the same time, the incidence of treatment after three months was observed, among which the incidence of observation of the other side was 96%(48/50)/ that of the control group was 84%(42/50). There were statistically significant differences between the two groups in the comparison of clinical treatment effect and incidence, P < 0.05. Conclusion: The treatment scheme of salbutamol and phenergan is beneficial to the disease control of children with cough variant asthma, which not only improves the therapeutic effect, but also can prevent the recurrence of the disease, and is worthy of further promotion and application.
文摘Objective: to apply the combined therapy of shegan mahuang decoction and acupoint application in the treatment of acute exacerbation of bronchial asthma in children. Methods: the children with acute exacerbation of bronchial asthma who were treated in our hospital from January 2021 to January 2022 were selected as the research subjects, and the effects of different treatments were compared, including shegan mahuang decoction and acupoint application + shegan mahuang decoction. Results: after the effective treatment plan was implemented, the condition improved, especially the children treated with acupoint application + shegan mahuang decoction had a higher total effective rate, a lower incidence of adverse reactions, a good trend in FVC and other levels, and symptoms and signs. The scores were lower, and the children who received acupoint application treatment were relatively poor, and the difference was significant (P<0.05). Conclusion: in the treatment of acute exacerbation of bronchial asthma in children, shegan mahuang decoction combined with acupoint application has obvious application value and high safety, and plays a positive role in further shortening the course of the disease in children.
文摘Asthma prevalence in the United States and the world has been increasing, affecting millions including children (0 - 17 years old) and causing thousands of deaths every year at a societal cost of over billions of dollars. Further, it has been documented that asthma morbidity responds to socioeconomic variations. This study evaluates the relationship between asthma and five air pollutants along with socioeconomic status in Texas counties from 2005 to 2013. Air pollutants investigated were carbon monoxide (CO), nitrogen dioxide (NO<sub>2</sub>), ozone (O<sub>3</sub>), fine particulate matter (PM2.5), and sulfur dioxide (SO<sub>2</sub>). Exploratory and spatial analyses produced consistent results. Asthma prevalence was positively associated with PM2.5, SO<sub>2</sub>, living near a park, and living in an urban area. Asthma childhood prevalence rates were positively associated with living in a household with a female head and negatively associated with ethnicity: Caucasian, Hispanic, and African American. Adult prevalence rates were positively associated with living in a household with female head, being on food stamps, and PM2.5. Both the overall and adult rates were positively associated with poverty. Asthma hospitalizations in Texas were positively associated with aerosol particles, sulfur dioxide, and low income. Moreover, the majority of air pollution in Texas is formed by stationary sources, which contradicts recent claims that mobile sources are the main emitters in Texas. Our findings are consistent with those from other geographical locations and suggest that additional studies and measures are required to fully explain the associations detected and underlying cause and effect paradigm.

文摘Objective To analyze the prevalence of asthma and asthma related symptoms among children aged 0-14 years in three Chinese cities and to obtain a crude estimation of the trend of childhood asthma prevalence in China. Methods A cross-sectional, population-based survey of prevalence of asthrna was conducted in children aged from 0 to 14 years in 3 major cities of China （Beijing, Chongqing, and Guangzhou） with different geographic locations. All the subjects were randomly selected by a multi-stage sampling method. Three to five schools and kindergartens in 2 urban districts in each city were randomly selected for the survey, and a validated questionnaire that included the core questions of the International Study of Asthma and Allergies in Childhood, Phase III questionnaire and several additional questions were used. All questionnaires were completed by parents or guardians of the selected children. Children whose parents responded affirmatively to the question＂ Has your child ever been diagnosed as asthma by a doctor＂ were recognized as victims of asthma. Results The prevalence of asthma in Beijing, Chongqing, and Guangzhou was 3.15%, 7.45%, and 2.09%, respectively. These values were significantly higher than those obtained 10 years ago in the national epidemiological survey in 2000 which used the same method of investigation and the same diagnotic criteria （x^2=3.938, P=-0.047; 22=73.506, P≤0.001; x^2=11.956, P=0.001, in each city）. Of the asthmatic children 57.21%, 69.91%, and 60.00% had their first attack before the age of 3 in Beijing, Chongqing, and Guangzhou, respectively. Wheezing was the primary clinical manifestation for all asthmatic children, followed by persistent cough and repeated respiratory infections. Both the prevalence of asthma and asthma-related symptoms were statistically higher in males than in females. Conclusion The prevalence of childhood asthma is statistically higher than that 10 years ago in the three Chinese cities.
文摘Today the most important challenge facing the pediatrician is the increasing prevalence of chronic diseases. With this regard, pediatricians play a key role in the management of these conditions. The closeness with the family, the knowledge of the clinical case and the care continuity allow the pediatrician to acquire a position of director of every case. When pathological events have a chronic feature, suddenly the quality of life of the whole family changes. For this reason the first communication of chronic disease is very important and the task of the pediatrician should be to provide a positive message to help the family in facing the difficulty of this new challenge. The bronchial asthma is the most common chronic disease worldwide. The incidence, the prevalence, and the mortality of the disease have increased in children over the past decades. These trends are particularly marked above all in preschool children. The success reached by Pediatricians is closely related to the compliance and the implementation of the therapy followed by the little patient and his family. With this regard authors, in this review, focus on the illustration of several strategies, based on the pediatrician’ skills and medicine documents, that can be used for the improvement of communication among pedia- trician-family and child, never forgetting the hu- man aspect of the same doctor, that should con- ciliate with the scientific knowledge in the taking care of a specific chronic disease.
文摘AIM To find the association between asthma and different types of functional abdominal pain disorders(FAPDs) among teenagers. METHOD A cross-sectional study was conducted among 13 to 15-year-old children from six randomly selected schools in Anuradhapura district of Sri Lanka. Data were collected using translated and validated selfadministered questionnaires(Rome Ⅲ questionnaire, International Study on Asthma and Allergies in Childhood questionnaire, and Pediatric Quality of Life Inventory 4.0) and administered under an examination setting after obtaining parental consent and assent.RESULTS Of the 1101 children included in the analysis, 157(14.3%) had asthma and 101(9.2%) had at least one FAPDs. Of children with asthma, 19.1% had at least one type of FAPDs. Prevalence rates of functional abdominal pain(FAP)(8.9% vs 3.3% in nonasthmatics), functional dyspepsia(FD)(2.5% vs 0.7%), and abdominal migraine(AM)(3.2% vs 0.4%) were higher in those with asthma(P < 0.05, multiple logistic regression analysis), but not in those with irritable bowel syndrome(4.5% vs 3.1%, P = 0.2). Severe abdominal pain(10.8% vs 4.6%), bloating(16.6% vs 9.6%), nausea(6.4% vs 2.9%), and anorexia(24.2% vs 16.2%) were more prevalent among asthmatics(P < 0.05). Lower gastrointestinal symptoms did not show a significant difference. Scores obtained for health related quality of life(HRQoL) were lower in those with asthma and FAPDs(P < 0.05, unpaired t-test).CONCLUSION Asthma is associated with three different types of FAPDs, namely, FD, AM, and FAP. HRQoL is significantly impaired in teenagers with asthma and FAPDs.
文摘<strong>Objective:</strong> To explore the close relationship between respiratory syncytial virus (RSV) infection and acute attack of childhood asthma. <strong>Methods:</strong> A computer-based search of database from Pumbed, CNKI, Wanfang, Baidu Scholar, Chongqing VIP, GeenMedica was performed to screen the articles about respiratory syncytial virus infection and childhood asthma. Then the literatures were screened out by the selection criteria. The RevMan5.3 software was used to test the heterogeneity and effect values of each study, analyze the sensitivity and publication bias of the literature, and draw on Meta forest plot and Funnel plot. <strong>Results:</strong> 5 articles conformed to the selection criteria. There were totally 881 cases in the case group, 826 cases in the control group. The results of heterogeneity test showed no heterogeneity between each study (P > 0.05). The fixed-effects model showed the 6.68 (5.06 - 8.82), (Z = 13.38, P < 0.00001). <strong>Conclusion:</strong> The infection rate of respiratory syncytial virus in children with acute asthma attack is higher than that in remission period. Respiratory syncytial virus infection rate can be used as an indicator of the severity of asthma in children.
