    Full Text Available Introduction: Asthmatic children are more at risk to environmental tobacco smoke exposure (ETS due to impaired lower airway function. Objective: To investigate the association of low socio-economic status and ETS exposure in asthmatic children. Design: A cross-sectional study on 425 primary school children (aged 5-11years in Merseyside, using a parent completed questionnaire and childrens’ saliva samples. Results: 25.9 % of children had doctor diagnosed asthma and 12 % had a history of hospital admission for respiratory illnesses. The symptom triad of cough, wheeze and breathlessness were reported for 8.5% of children. Mean cotinine level was 2.1 ng/ml (±0.6 SD. 45.6% of children were ETS exposed (cotinine levels >1.0 ng/ml. Asthmatic children and those from disadvantaged households were more likely to be ETS exposed, compared to non-asthmatic and those from advantaged households [OR=1.7 (95%CI=1.1-2.4] and [OR=2.1(1.8-3.2 respectively]. A synergic effect of parental asthma, deprivation and high cotinine levels on childhood asthma was observed in multivariate analysis. Conclusions: A high cotinine level was significantly associated with an increased risk of asthma in children particularly amongst disadvantaged households. Interventions aimed at limiting ETS exposure particularly among disadvantaged groups with asthmatic children are needed.

    Full Text Available Abstract Background Taffic-related air pollution has been related to adverse respiratory outcomes; however, there is still uncertainty concerning the type of vehicle emission causing most deleterious effects. Methods A panel study was conducted among 147 asthmatic and 50 healthy children, who were followed up for an average of 22 weeks. Incidence density of coughing, wheezing and breathing difficulty was assessed by referring to daily records of symptoms and child's medication. The association between exposure to pollutants and occurrence of symptoms was evaluated using mixed-effect models with binary response and poisson regression. Results Wheezing was found to relate significantly to air pollutants: an increase of 17.4 μg/m3 (IQR of PM2.5 (24-h average was associated with an 8.8% increase (95% CI: 2.4% to 15.5%; an increase of 34 ppb (IQR of NO2 (1-h maximum was associated with an 9.1% increase (95% CI: 2.3% to16.4% and an increase of 48 ppb (IQR in O3 levels (1 hr maximum to an increase of 10% (95% CI: 3.2% to 17.3%. Diesel-fueled motor vehicles were significantly associated with wheezing and bronchodilator use (IRR = 1.29; 95% CI: 1.03 to 1.62, and IRR = 1.32; 95% CI: 0.99 to 1.77, respectively, for an increase of 130 vehicles hourly, above the 24-hour average. Conclusion Respiratory symptoms in asthmatic children were significantly associated with exposure to traffic exhaust, especially from natural gas and diesel-fueled vehicles.

    Full Text Available Histamine plays an important role in the development of asthmatic symptoms. Diamine oxidase (DAO histaminase, which inactivates histamine, is located in the intestine and kidney and is released into plasma. Plasma DAO activity in asthmatic children was measured by a recently developed high performance liquid chromatographic method using histamine as the DAO substrate. Diamine oxidase activity was higher in severely asthmatic children than in those with mild asthma. A time course study during the acute exacerbation phase revealed that DAO activity rose during acute asthmatic attacks and then decreased gradually over several days. Although the mechanisms of plasma DAO activity increase during acute asthmatic attacks could not be explained, data showed that plasma DAO activity is an important index of histamine metabolism in asthmatics and may relate to some mechanisms of acute exacerbation of airway inflammation. Consequently, fluctuations in plasma DAO can be used as one of various indices of instability in management of asthma.

    Full Text Available Introduction. Bronchial hyperresponsiveness (BHR is a factor in predicting bronchial asthma independently of inflammation markers. Objective. The aims were to determine the frequency and important predictive facts of BHR and the effect of prophylaxis by Global Initiative for Asthma (GINA and National Asthma Education and Prevention Program (NAEPP on BHR in asthmatic children. Methods. BHR in 106 children was evaluated by the bronchoprovocation test with methacholine. Results. The prevalence rate of symptomatic BHR is 18% for crucial point of PC20=4.1±3.03 mg/ml and PD20=3.22±2.59 μmol methacholine. On average asthmatic children express moderate BHR, which persists even two years after administering prophylaxis. After two years bronchial reactivity is significantly smaller, the change of FEV1 is significantly smaller, the velocity of change of slope dose response curve (sDRC is faster and the provocative concentration of methacholine that causes wheezing is 2-3 times lower. A mild sDRC shows milder bronchoconstriction after two years. The fast change of bronchial reactivity in 41% of asthmatic children is contributed to aero-pollution with sulfur dioxide and/ or, possible insufficient and/or inadequate treatment during two years of administering prophylaxis. A simultaneous effect of allergens from home environment and grass and tree pollens and of excessive aero-pollution on children’s airways is important in the onset of symptomatic BHR. After two years of treatment by GINA and NAEPP children do not show asthma symptoms or show mild asthma symptoms, however bronchial sensitivity remains unchanged. Conclusion. Optimal duration of anti-inflammatory treatment in asthmatic children who show moderate bronchial hyperresponsiveness should be longer than two years.

    Full Text Available Asthma is the most frequent chronic inflammatory disease in childhood, and its prevalence has increased remarkably over the last decades. Therefore, the scientific community became interested in studying the growth of the affected children. The relationship between asthma and growth suffers the influence of the clinical picture, of therapeutics, but the different study methods make it difficult to distinguish the factors responsible for the growth retardation detected by some authors. This review has the purpose of providing an overall outlook on this matter.

    Acute asthma attack in children is an attack responsible for life-threatening acute respiratory distress with partial or no response to bronchodilator drugs. The severity of the episode needs to be quickly evaluated. This presupposes a perfect knowledge of the clinical signs of severity. Treatment is urgent and first based on the administration of high doses of inhaled short-acting beta 2-agonists. In the more obstructed children, anti-cholinergic drugs can be added to nebulized beta 2-agonists. Because of their delayed effect, systemic steroids require an early prescription. Symptomatic treatments are: urgent hospitalization, oxygen if needed, proper hydratation. Continuous nebulization or intravenous perfusion of beta 2-agonists are prescribed with cardiac monitoring when no objective improvement is noted. Admission into the pediatric intensive care unit when bronchial obstruction continues will permit the association of bronchodilator drugs and the proposal of mechanical ventilation if needed. When the episode is resolved, a prophylactic treatment using inhaled corticosteroids must be prescribed. Clinical and spirometric follow-up has to be organized, and the patient and his/her family have to be educated.

    Full Text Available Asthma is one of the most common chronic diseases of childhood. Inhaled corticosteroids (ICS are the recommended controller drug for asthma treatment. The aim of our study was to determine concerns and fears of parents of children with asthma towards the use of ICS. One hundred parents of asthmatic children were interviewed using structural questionnaire. Airway inflammation was reported by only 6% of interviewed parents, whereas airway narrowing was addressed by 34%. Interesting data, 71% of parents were concerned with the role of steroids in asthma treatment, but more than half (53% of them addressed fears from side effects. Apparent gaps were found in knowledge of parents of asthmatic children about ICS as controller asthma medication. So, physician and health providers should explain to asthmatic parents that airway inflammation is the core for asthma management. This may remove fears about ICS and thus improve adherence to treatment.

    The aim of this prospective case control study is to determine CD4(+), CD25(+), and FoxP3(+) T regulatory cells (Tregs) and T helper cells (Ths) in obese, asthmatic, asthmatic obese, and healthy children. Obese (n = 40), asthmatic (n = 40), asthmatic obese (n = 40), and healthy children (n = 40) were included in this study. Blood samples collected from children were marked with CD4, CD25, ve Foxp3 in order to detect Tregs and Ths by flow cytometric method. Statistical analyses were performed. p ≤ 0.05 was chosen as meaningful threshold. Tregs exhibiting anti-inflammatory nature were significantly lower in obese (0.16 %; p ≤ 0.001), asthmatic (0.25 %; p ≤ 0.01), and asthmatic obese (0.29 %; p ≤ 0.05) groups than control group (0.38 %). Ths were counted higher in asthma group than control (p ≤ 0.01) and obese (p ≤ 0.001) groups. T cell immunity plays important roles in chronic inflammatory diseases such as obesity and asthma pathogeneses. Decreased numbers of Tregs found in obese, asthmatic, and asthmatic obese children might represent a challenge of these cells.

    Asthma and obesity are two common disorders often associated in children and characterized by an inflammatory status. Growing evidences support a connection between obesity and asthma since weight reduction can improve asthmatic symptoms. In this study, we have enrolled eighty children: 17 non asthmatics and non obese, 19 obese, 28 asthmatics-obese and, 16 asthmatics non-obese, respectively. In all participants, respiratory functional tests and body mass index (BMI) were calculated. Moreover, systemic inflammation of biomarkers such as T helper (h)1-type, Th2-type and T regulatory-type serum cytokines along with major adipokines was determined. Data will show that the association between asthma and obesity leads to a predominant Th1-type response with an increase in pro-inflammatory cytokines. This inflammatory profile in asthmatics-obese children is sustained by elevated serum levels of leptin and visfatin, while adiponectin concentration is rather diminished. Finally, levels of systemic inflammatory biomarkers positively correlate with the increase in BMI values in all population subgroups.

    Full Text Available Introduction. For future health planning of our country, the type and amount of drugs used for treatment of chronic diseases should be known. Therefore, in the present study the treatment regimen of asthmatic children in the city of Mashhad was studied. Methods. To study the different types of drugs in the treatment regimen of asthmatic children in the city of Mashhad, we evaluated the treatment regimen of 366 primary school children with asthma disease. Starting, maximum and duration of action of three different bronchodilators (salbutamol inhaler, salbutamol syrup, and theophylline syrup were compared. Findings. The results of the first part of this study showed that only 31.6 percent of asthmatic children had history of treatment and only 10.6 percent had current medication. In addition, most of the treated children (38.8 percent had only bronchodilator (salbutamol syrup in their treatment regimen. The effect of salbutamol inhaler on lung function tests starts in 5 min, salbutamol syrup in 15 min and theophylline syrup at 30 min after administration. The maximum response to salbutamol inhaler, salbutamol syrup, and theophylline syrup occurred 15 min, 4 hr and 3 hr after administration, respectively. The reduction of response to salbutamol inhaler occurs after 3 hr, but there was no any reduction in response to salbutamol and theophylline syrup during study period. Conclusion. The prevalence of asthma among children in the city of Mashhad is relatively high, but most of asthmatic children are not treated. Although the oral bronchodilator in mild asthma is effective, salbutamol inhaler is needed for emergency use.

    The aim of this study was to assess the role of European ambulatory pediatricians in caring for asthmatic children, especially in terms of their therapeutic education. We developed a survey that was observational, declarative, retrospective and anonymous in nature. 436 ambulatory pediatricians in Belgium, France, Germany, Italy, Luxembourg and Slovenia were asked to participate in the survey providing information on three children over 6 years old suffering from persistent asthma, who had been followed for at least 6 months. We considered the pediatricians' profile, and their role in the therapeutic education of children. 277 pediatricians (64%) responded: 81% were primary care pediatricians; 46% participated in networks; 4% had specific training in Therapeutic Patient Education; 69% followed more than 5 asthmatic children per month, and over long periods (7 ± 4 years). The profiles of 684 children were assessed. Answers diverged concerning the provision of a Personalized Action Plan (60-88%), training the child to measure and interpret his Peak Expiratory Flow (31-99%), and the prescription of pulmonary function tests during the follow-up programme of consultations (62-97%). Answers converged on pediatricians' perception of their role in teaching children about their condition and its treatment (99%), about inhalation techniques (96%), and in improving the children's ability to take preventive measures when faced with risk situations (97%). This study highlights the role of European pediatricians in caring for asthmatic children, and their lack of training in Therapeutic Patient Education. Programmes and tools are required in order to train ambulatory pediatricians in Therapeutic Patient Education, and such resources should be integrated into primary health care, and harmonized at the European level.

    Full Text Available OBJECTIVE: A case-control study of patients with pneumonia was conducted to investigate whether wheezing diseases could be a risk factor. METHODS: A random sample was taken from a general university hospital in S. Paulo City between March and August 1994 comprising 51 cases of pneumonia paired by age and sex to 51 non-respiratory controls and 51 healthy controls. Data collection was carried out by two senior paediatricians. Diagnoses of pneumonia and presence of wheezing disease were independently established by each paediatrician for both cases and controls. Pneumonia was radiologically confirmed and repeatability of information on wheezing diseases was measured. Logistic regression analysis was used to identify risk factors. RESULTS: Wheezing diseases, interpreted as proxies of asthma, were found to be an important risk factor for pneumonia with an odds ratio of 7.07 (95%CI= 2.34-21.36, when the effects of bedroom crowding (odds ratio = 1.49 per person, 95%CI= 0.95-2.32 and of low family income (odds ratio = 5.59 against high family income, 95%CI= 1.38-22.63 were controlled. The risk of pneumonia attributable to wheezing diseases is tentatively calculated at 51.42%. CONCLUSION: It is concluded that at practice level asthmatics should deserve proper surveillance for infection and that at public health level pneumonia incidence could be reduced if current World Health Organisation's guidelines were reviewed as to include comprehensive care for this illness.

    Full Text Available The T cell hypothesis of asthma is based on the concept that the disease is driven and maintained by the persistence of a specialized subset of chronically activated T memory cells sensitized against an array of allergenic, occupational or viral antigens. Overreaction of CD4+ T cells in the peripheral blood and airway tissues is an invariant feature of asthma; therefore a potent mechanism for augmenting the number of activated T cells in this disease would be the resistance to the normally programmed pathway for cell death. The aim of the study was to evaluate the presence of apoptotic markers on peripheral blood lymphocytes from healthy and asthmatic children before and after stimulation with antiCD95 antibodies. The blood was collected from 21 children with atopic asthma suffering from allergic rhinitis because of house dust mite and/or grass pollen allergens and 8 healthy children matched for their age and sex. Blood was mixed with purified monoclonal antibody antiCD95 (Beckman Coulter, incubated for 24 hours and than stained with Annexin V andPI (Becton Dickinson. Prepared suspensions were analyzed with Cytomics FC 500 (Beckman Coulter flow cytometer. Annexin V(+/PI(- cells were characterized as early apoptotic, Annexin V(+/PI(+ as late apoptotic and Annexin V(-/PI(+ as dead. In unstimulated sample from asthmatic children 21.09+/-11.20% cells were characterized as Annexin V positive/PI negative. After stimulation with antiCD95 Annexin V positive/PI negative cells constituted 18.72+/-9.42% of cells, p=0.1. In unstimulated sample from healthy children 11.69+/-6.70% cells were characterized as Annexin V positive/PI negative. In the sample stimulated with antiCD95 16.54+/-2.98% of cells were Annexin V positive/PI negative, p=0.02. There were no differences between results of late apoptotic and necrotic lymphocytes from healthy and asthmatic children. Performed research indicates that lymphocytes from asthmatic children are resistant to Fas

    The home is increasingly associated with asthma. It acts both as a reservoir of asthma triggers and as a refuge from seasonal outdoor allergen exposure. Racial/ethnic minority families with low incomes tend to reside in neighborhoods with low housing quality. These families also have higher rates of asthma. This study explores the hypothesis that black and Latino urban households with asthmatic children experienced more home mechanical, structural condition-related areas of concern than white households with asthmatic children. Participant families (n = 140) took part in the Kansas City Safe and Healthy Homes Program, had at least one asthmatic child, and met income qualifications of no more than 80% of local median income; many were below 50%. Families self-identified their race. Homes were assessed by environmental health professionals using a standard set of criteria and a specific set of on-site and laboratory sampling and analyses. Homes were given a score for areas of concern between 0 (best) and 53 (worst). The study population self-identified as black (46%), non-Latino white (26%), Latino (14.3%), and other (12.9%). Mean number of areas of concern were 18.7 in Latino homes, 17.8 in black homes, 13.3 in other homes, and 13.2 in white homes. Latino and black homes had significantly more areas of concern. White families were also more likely to be in the upper portion of the income. In this set of 140 low-income homes with an asthmatic child, households of minority individuals had more areas of condition concerns and generally lower income than other families.

    Neck accessory respiratory muscles and mouth breathing suggest a direct relationship among asthma, Temporomandibular (TMD) and Cervical Spine (CSD) Disorders. This study was performed to evaluate and correlate TMD, CSD in asthmatic and non-asthmatic. Thirty asthmatic children (7.1 +/- 2.6 years old), 30 non-asthmatic predominantly mouth breathing children (Mouth Breathing Group - MBG) (8.80 +/- 1.61 years) and 30 non-asthmatic predominantly nasal breathing children (Nasal breathing Group - NBG) (9.00 +/- 1.64 years) participated in this study and they were submitted to clinical index to evaluate stomatognathic and cervical systems. Spearman correlation test and Chi-square were used. The level of significance was set at p temporomandibular joint (TMJ), TMJ sounds, pain during cervical extension and rotation, palpatory tenderness of sternocleidomastoids and paravertabrae muscles and a severe reduction in cervical range of motion were observed in AG. Both AG and MBG groups demonstrated palpatory tenderness of posterior TMJ, medial and lateral pterygoid, and trapezius muscles when compared to NBG. Results showed a positive correlation between the severity of TMD and CSD signs in asthmatic children (r = 0.48). No child was considered normal to CSD and cervical mobility. The possible shortening of neck accessory muscles of respiration and mouth breathing could explain the relationship observed between TMD, CSD signs in asthmatic children and emphasize the importance of the assessment of temporomandibular and cervical spine regions in asthmatic children.

    Full Text Available Abstract Background The role of leukotriene (LT B4, a potent inflammatory mediator, in atopic asthmatic and atopic nonasthmatic children is largely unknown. The lack of a gold standard technique for measuring LTB4 in exhaled breath condensate (EBC has hampered its quantitative assessment in this biological fluid. We sought to measure LTB4 in EBC in atopic asthmatic children and atopic nonasthmatic children. Exhaled nitric oxide (NO was measured as an independent marker of airway inflammation. Methods Fifteen healthy children, 20 atopic nonasthmatic children, 25 steroid-naïve atopic asthmatic children, and 22 atopic asthmatic children receiving inhaled corticosteroids were studied. The study design was of cross-sectional type. Exhaled LTB4 concentrations were measured using liquid chromatography/mass spectrometry-mass spectrometry (LC/MS/MS with a triple quadrupole mass spectrometer. Exhaled NO was measured by chemiluminescence with a single breath on-line method. LTB4 values were expressed as the total amount (in pg of eicosanoid expired in the 15-minute breath test. Kruskal-Wallis test was used to compare groups. Results Compared with healthy children [87.5 (82.5–102.5 pg, median and interquartile range], exhaled LTB4 was increased in steroid-naïve atopic asthmatic [255.1 (175.0–314.7 pg, p 4 than steroid-naïve asthmatics [125.0 (25.0–245.0 pg vs 255.1 (175.0–314.7 pg, p Conclusion In contrast to exhaled NO concentrations, exhaled LTB4 values are selectively elevated in steroid-naïve atopic asthmatic children, but not in atopic nonasthmatic children. Although placebo control studies are warranted, inhaled corticosteroids seem to reduce exhaled LTB4 in asthmatic children. LC/MS/MS analysis of exhaled LTB4 might provide a non-invasive, sensitive, and quantitative method for airway inflammation assessment in asthmatic children.

    Full Text Available Fitness improvement was used to compare morning with afternoon exercise periods for asthmatic children. Children with persistent moderate asthma (according to GINA criteria, 8 to 11 years old, were divided into 3 groups: morning training group (N = 23, afternoon training group (N = 23, and non-training group (N = 23. The program was based on twice a week 90-min sessions for 4 months. We measured the 9-min running distance, resting heart rate and abdominal muscle strength (sit-up number before and after the training. All children took budesonide, 400 µg/day, and an on demand inhaled ß-agonist. The distance covered in 9 min increased (mean ± SEM from 1344 ± 30 m by 248 ± 30 m for the morning group, from 1327 ± 30 m by 162 ± 20 m for the afternoon group, and from 1310 ± 20 m by 2 ± 20 m for the control group (P 0.05 for morning with afternoon comparison. The reduction of resting heart rate from 83 ± 1, 85 ± 2 and 86 ± 1 bpm was 5.1 ± 0.8 bpm in the morning group, 4.4 ± 0.8 bpm in the afternoon group, and -0.2 ± 0.7 bpm in the control group (P > 0.05 for morning with afternoon comparison and P 0.05 for morning with afternoon comparison and P < 0.05 versus control. No statistically significant differences were detected between the morning and afternoon groups in terms of physical training of asthmatic children.

    The stress system co-ordinates the adaptive responses of the organism to stressors of any kind. Inappropriate responsiveness may account for increased susceptibility to a variety of disorders, including asthma. Accumulated evidence from animal models suggests that exogenously applied stress enhances airway reactivity and increases allergen-induced airway inflammation. This is in agreement with the clinical observation that stressful life events increase the risk of a new asthma attack. Activation of the hypothalamic-pituitary-adrenal (HPA) axis by specific cytokines increases the release of cortisol, which in turn feeds back and suppresses the immune reaction. Data from animal models suggest that inability to increase glucocorticoid production in response to stress is associated with increased airway inflammation with mechanical dysfunction of the lungs. Recently, a growing body of evidence shows that asthmatic subjects who are not treated with inhaled corticosteroids (ICS) are likely to have an attenuated activity and/or responsiveness of their HPA axis. In line with this concept, most asthmatic children demonstrate improved HPA axis responsiveness on conventional doses of ICS, as their airway inflammation subsides. Few patients may experience further deterioration of adrenal function, a phenomenon which may be genetically determined.

    The purpose of this study was to evaluate the HRCT findings of bronchial asthma during maintenance bronchodilator therapy and to determine whether there were irreversible bronchial changes occurred in pediatric patients with this condition. HRCT findings of the lung in 21 asthmatic children (14 boys and 7 girls aged between 3.5 and 13.8 (mean: 7.7) years) who were receiving maintenance bronchodilator therapy were retrospectively studied. At the time of CT examination, 16 were receiving nonsteroid bronchodilator therapy only, and five were receiving both bronchodilator and steroid therapy. Thirteen patients were defined as allergic and eight were nonallergic. The clinical severity of chronic asthma was graded as severe in seven cases, and moderate in 14. The duration of the disease ranged from 4 months to 6 years (mean 3.2 years). HRCT was performed in 19 cases for evaluation of the atelectasis, hyperinflation, and prominent bronchovascular bundles seen on plain radiographs, and in two cases for evaluation following acute exacerbation. A CT W-2000 scanner (Hitachi Medical Co. Tokyo, Japan) was used during the end inspiratory phase, and in addition, ten patients were scanned during the expiratory phase. Scans were reviewed for evidence of bronchial thickening, bronchiectasis, emphysema, abnormal density, mucus plugs, and other morphological abnormalities. The presence of bronchial wall thickening or air trapping was evaluated according to the duration, severity and type of asthma. Among the 21 patients, 7 (33.3%) had normal HRCT findings, while in 14 (66.7%), bronchial wall thickening was demonstrated. Eleven of the 14 patients with bronchial wall thickening(78.6%) also had air trapping. No patient was suffering from bronchiectasis or emphysema. There were no statistically significant correlations between the presence of bronchial wall thickening or air trapping and the duration of the disease, its severity, or type of asthma.

    Full Text Available Asthma is a chronic inflammatory disorder of the airways, which is diagnosed by periodic symptoms of inflammation, bronchial spasm, and increased mucosal secretions. It has higher incidence among the preschool children. There are many contradictory reports based on the effect of asthma on oral health, however it has been hypothesized that asthma could lead to poor oral health. The objective of the present study was to investigate oral health indices in 44 preschool children of three to six years old with mild to moderate asthma and 46 matched healthy children in Tehran Children's Respiratory Center.Dental plaque, gingival inflammation, mouth breathing, and dental caries were evaluated by one trained examiner according to World Health Organization [WHO] criteria. Culture and colony counting of streptococcus mutans and lactobacillus species were carried out in saliva specimens of the patients. The effects of different factors on the colony counts were statistically analyzed using linear regression analysis.The level of mother’s education and preexisting asthma disease in children had significant effect  on  the  colony counts  of  streptococcus  species whereas no  factor  was found  to influence the number of lactobacillus counts significantly. The results indicated no significant differences between the children with asthma and those without asthma regarding (decayed, missing, filled, teeth dmft index (mean of 3.34 in asthmatic children and 3.0 in the control group.Therefore, it can be deduced that the presence of asthma disease did not increase the probability of tooth decay.

    Venipuncture testing of adrenocortical function in asthmatic infants and young children receiving inhaled corticosteroids can raise cortisol levels and mask physiological responses. This study aimed to establish reference ranges for salivary cortisol levels and evaluate the safety and effects of jet-nebulized budesonide inhalation suspension (BIS) on salivary cortisol levels and patient outcomes in infants and young children with mild or persistent asthma. Reference salivary cortisol levels were determined in healthy children aged 6 months to 4 years old. A 12-week multicenter, randomized, parallel-group, open-label study was performed involving 53 age-matched asthmatic children who received either 0.5 mg/day of BIS or 40-60 mg/day of cromolyn sodium inhalation suspension (CIS) via compressor nebulizer. The effective measuring range of salivary cortisol concentration in asthmatic children was 0.12-3.00 micrograms/dL. The upper and lower limits of the reference range were 0.827 and 0.076 micrograms/dL, respectively. No significant difference was seen from baseline through week 12 in the CIS and BIS groups. BIS was safe in these patients, with no inhibitory effects on adrenocortical function. Salivary cortisol measurement offers a useful and accurate tool for testing adrenocortical function in infants and young children. Longer-term studies that incorporate testing of the hypothalamic-pituitary-adrenal axis are warranted to confirm our findings.

    Background: It is well established that short-term exposure to ambient air pollutants can exacerbate asthma, the role of early life or long-term exposure is less clear. We assessed the association between severe asthma exacerbations with both birth and annual exposure to outdoor air pollutants with a population-based cohort of asthmatic children in the province of Quebec (Canada). Method: Exacerbations of asthma occurring between 1 April 1996 and 31 March 2011 were defined as one hospitalization or emergency room visit with a diagnosis of asthma for children (<13 years old) already diagnosed with asthma. Annual daily average concentrations of ozone (O3) and nitrogen dioxide (NO2) were estimated at the child’s residential postal code. Satellite based levels of fine particulate (PM2.5) estimated for a grid of 10 km by 10 km were also assigned to postal codes of residence for the whole province. Hazard ratios (HRs) were estimated from Cox models with a gap time approach for both birth and time-dependant exposure. Results: Of the 162,752 asthmatic children followed (1,020,280 person-years), 35,229 had at least one asthma exacerbation. The HRs stratified by age groups and adjusted for the year of birth, the ordinal number of exacerbations, sex, as well as material and social deprivation, showed an interquartile range increase in the time-dependant exposure to NO2 (4.95 ppb), O3 (3.85 ppb), and PM2.5 (1.82 μg/m3) of 1.095 (95% CI 1.058–1.131), 1.052 (95% CI 1.037–1.066) and 1.025 (95% CI 1.017–1.031), respectively. While a positive association was found to PM2.5, no associations were found between exposure at birth to NO2 or O3. Conclusions: Our results support the conclusion, within the limitation of this study, that asthma exacerbations in asthmatic children are mainly associated with time dependent residential exposures less with exposure at birth.

    Full Text Available The development of asthma appears to involve interplay between host factors and environmental exposures. The most important environmental factors are viral respiratory infections and airborne allergens in consist of sensitization to fungal aeroallergens [1]. Exposure to fungal aeroallergens was reported to be a cause of asthma in many parts of the world.There are few data on the prevalence of allergy to molds in Iran. This study was performed to determine the positive skin prick test to molds and their related risk factors in asthmatic children in Shiraz, southern Iran (Table 1.Skin prick test was done in two hundred and thirty asthmatic children with five types of common fungal aeroallergens (Aspergillus fumigatus, Caldosporium herbarum, Penicillium, Alternaria and Rhizopus.Out of 230 asthmatic children (175 boys, 55 girls with mean age 6.34±3 years, 25 (10.9% had positive skin test to molds. In other studies this rate was reported to be different between 2% to 80%[2]. Of 25 children with positive skin test to molds, the common fungal aeroallergen was Aspergillus followed by Cladosporium, Alternaria, Penicillium and Rhizopus. Amin R et al studied airborne fungal spores in Shiraz. The most important fungi, in order of numbers, had been Altenaria, Aspergilus, Rhizopus and Penicillium[3]. With regard to results of skin prick test in our study, it seems that Alternia is the most common outdoor fungus, but Aspergillus could be the most important indoor fungus.Another study showed in asthmatic patients that main skin test reactivity to fungi was for Aspergillus but most frequent cultured fungus was Cladosporium[4].Of 25 subjects with positive skin test to molds, 5 (20% were females, 20 (80% were residents of urban areas and 4 (56% lived in homes older than ten years. There was no significant correlation between the prevalence of mold skin test positivity in males and females, rural and urban habitats and age of homes.There was no difference in the

    Full Text Available Background Asthma is a chronic inflammatory process which involve variety of cells such as inflammatory mediators, reactive oxygen species (ROS, and cytokines. The inflammatory process would be exacerbated in the presence of oxidative stress. Superoxide dismutase (SOD is the first important enzyme to protect the respiratory tract against oxidative stress. The decreased of SOD has a correlation with increased of airway obstruction and bronchospasm. Objective To assess for a correlation between superoxide dismutase (SOD levels and peak expiratory flow, as well as to determine the impact of SOD levels for predicting asthma attacks. Methods We conducted a prospective cohort study at Dr. Sardjito Hospital, Yogyakarta, between February and April 2011 involving asthmatic children aged 5-18 years. Subjects’ serum SOD levels and peak expiratory flow were measured at the same time point. We then performed a prospective study following up on the same subjects to find out if they had a recurrent asthma attack within one month of the tests. We also reassessed their peak expiratory flow one month after blood specimens were obtained. Results Thirty-nine patients were enrolled in this study. There was no significant correlation between SOD level and peak expiratory flow [r=0.289; 95%CI -0.025 to 0.47; P=0.074]. However, older age was significantly associated with higher peak expiratory flow (=0.5; 95%CI 3.10 to 11.57; P=0.01. Lower levels of SOD increased the risk of asthma attacks in a month following the initial measurements (RR=5.5; 95%CI 1.6 to 18.9; P=0.009. Conclusion Superoxide dismutase (SOD level is not significantly associated with peak expiratory flow. However, we find a relationship between older age and higher peak expiratory flow and a relationship between lower SOD levels and risk of asthma attacks within one month following the tests.

    Rationale. The sleep-related factors that modulate the nocturnal worsening of asthma in children are poorly understood. This study addressed the hypothesis that asthmatic children have a REM sleep-related vulnerability trait that is independent of OSA. Methods. We conducted a retrospective cross-sectional analysis of pulse-oximetry signals obtained during REM and NREM sleep in control and asthmatic children (n = 134). Asthma classification was based on preestablished clinical criteria. Multivariate linear regression model was built to control for potential confounders (significance level P ≤ 0.05). Results. Our data demonstrated that (1) baseline nocturnal respiratory parameters were not significantly different in asthmatic versus control children, (2) the maximal % of SaO2 desaturation during REM, but not during NREM, was significantly higher in asthmatic children, and (3) multivariate analysis revealed that the association between asthma and REM-related maximal % SaO2 desaturation was independent of demographic variables. Conclusion. These results demonstrate that children with asthma have a REM-related vulnerability trait that impacts oxygenation independently of OSA. Further research is needed to delineate the REM sleep neurobiological mechanisms that modulate the phenotypical expression of nocturnal asthma in children. PMID:24288619

    This study lends support to the utility of a compliance-adapted health belief framework for exploring mothers' differential adherence to medication regiments prescribed for their asthmatic children. Most of the Model components behaved as hypothesized in predicting mothers' drug administration. The findings offer empirical evidence which can be applied to the purposes of identifying potential noncompliers and designating those specific, health-related orientations of the mother which are related to poor cooperation with therapy. Based on an educational diagnosis, the clinician may thus intervene to alter inappropriate health beliefs in order to enhance the likelihood of compliance for the asthmatic patient.

    Background. Exhaled nitric oxide (FeNO) has been reported to be elevated in the oxidative stress involved in asthmatic patients, and the reaction of nitric oxide (NO) with superoxide anions results in the formation of nitrotyrosine. The purpose of this study was to investigate the effect of inhaled steroid treatment on nitrotyrosine levels collected by exhaled breath condensate (EBC) and on FeNO. Methods. This was a single-blind placebo-controlled study. The lung function, FeNO, and nitrotyrosine levels were evaluated in 10 asthmatic children. Results. The nitrotyrosine levels were stable during the placebo period (T0 = 1.16 ng/ml versus T1 = 1.05 ng/ml; NS.), whereas they decreased after the treatment with flunisolide (T2 = 1.14 ng/ml versus T3 = 0.88 ng/ml; P < .001). No significant reduction in FeNO levels was observed after placebo treatment (T0 = 38.4 ppb versus T1 = 34.7 ppb, NS.). In contrast, FeNO values decreased significantly being at T3 = 14.9 ppb (T1 versus T3; P = .024). Conclusions. This study shows that corticosteroid treatment reduces nitrotyrosine levels in EBC of asthmatic subjects. PMID:17047290

    Inhaled budesonide and salbutamol represent the most important and frequently used drugs in asthmatic children during acute exacerbation. However, there is still no consensus about their resulting metabolic derangements; thus, this study was conducted to determine the distinct metabolic profiles of these two drugs. A total of 69 children with asthma during acute exacerbation were included, and their serum and urine were investigated using high-resolution nuclear magnetic resonance (NMR). A metabolomics analysis was performed using a principal component analysis and orthogonal signal correction-partial least squares using SIMCA-P. The different metabolites were identified, and the distinct metabolic profiles were analysed using MetPA. A high-resolution NMR-based serum and urine metabolomics approach was established to study the overall metabolic changes after inhaled budesonide and salbutamol in asthmatic children during acute exacerbation. The perturbed metabolites included 22 different metabolites in the serum and 21 metabolites in the urine. Based on an integrated analysis, the changed metabolites included the following: increased 4-hydroxybutyrate, lactate, cis-aconitate, 5-hydroxyindoleacetate, taurine, trans-4-hydroxy-l-proline, tiglylglycine, 3-hydroxybutyrate, 3-methylhistidine, glucose, cis-aconitate, 2-deoxyinosine and 2-aminoadipate; and decreased alanine, glycerol, arginine, glycylproline, 2-hydroxy-3-methylvalerate, creatine, citrulline, glutamate, asparagine, 2-hydroxyvalerate, citrate, homoserine, histamine, sn-glycero-3-phosphocholine, sarcosine, ornithine, creatinine, glycine, isoleucine and trimethylamine N-oxide. The MetPA analysis revealed seven involved metabolic pathways: arginine and proline metabolism; taurine and hypotaurine metabolism; glycine, serine and threonine metabolism; glyoxylate and dicarboxylate metabolism; methane metabolism; citrate cycle; and pyruvate metabolism. The perturbed metabolic profiles suggest potential metabolic

    Full Text Available Abstract Background We previously reported that asthmatic children with GSTM1 null genotype may be more susceptible to the acute effect of ozone on the small airways and might benefit from antioxidant supplementation. This study aims to assess the acute effect of ozone on lung function (FEF25-75 in asthmatic children according to dietary intake of vitamin C and the number of putative risk alleles in three antioxidant genes: GSTM1, GSTP1 (rs1695, and NQO1 (rs1800566. Methods 257 asthmatic children from two cohort studies conducted in Mexico City were included. Stratified linear mixed models with random intercepts and random slopes on ozone were used. Potential confounding by ethnicity was assessed. Analyses were conducted under single gene and genotype score approaches. Results The change in FEF25-75 per interquartile range (60 ppb of ozone in persistent asthmatic children with low vitamin C intake and GSTM1 null was −91.2 ml/s (p = 0.06. Persistent asthmatic children with 4 to 6 risk alleles and low vitamin C intake showed an average decrement in FEF25-75 of 97.2 ml/s per 60 ppb of ozone (p = 0.03. In contrast in children with 1 to 3 risk alleles, acute effects of ozone on FEF25-75 did not differ by vitamin C intake. Conclusions Our results provide further evidence that asthmatic children predicted to have compromised antioxidant defense by virtue of genetic susceptibility combined with deficient antioxidant intake may be at increased risk of adverse effects of ozone on pulmonary function.

    Allergy diseases in our province have the characteristic of early appearance of asthma and predominant monosensitization to domestic dust mites due to the climatic condition. In this work we study the influence in allergic children. We selected 1028 mothers that brought their children to hospital for the first time. We divided them in two groups. One was comprised of 459 mothers of atopic children (MA) and another of 569 mothers of non atopic children (MC). All mothers were skin-prick tested (Phazet). The papula area, the mothers with aeroallergen sensitization, were 180 (17.5%) between MA 126 (27.4%) and MC 54 (9.5%). The diagnosis of allergic mothers was higher in MA than in MC. Asthma 8.39%, Rhinitis 4.75% and dermatitis 2%. 53.31% lived on the coast. 51.45% had house moulds. 31% had animals. 34.9% were smokers. There were more adverse drug reactions in MA than in MC. 180 mothers presented sensitization. D. pteronyssinus 66.3%, D. farinae 65.5% Lolium P. 14.55%, Cats 11.6% (MA > MC), Artemisia Vulgaris 6.25% and Cladosporium Herbarum 0.6%. There was no correlation between skin sensitization and domestic animals. There was no influence between children's IgE and mothers with skin sensitization. Skin sensitization to grass pollen correlated with the mother who was living in another country. The mothers who have been living more than five years in our province presented more skin sensitization to aero-allergens.

    Sixteen children aged under 5 years with chronic asthma completed a double-blind crossover trial of treatment with oral choline theophyllinate (6.7 mg/kg four times daily) and nebulised sodium cromoglycate (20 mg four times daily). The trial comprised three 8-week treatment periods during which active sodium cromoglycate, active choline theophyllinate, and placebo were given in random order. Symptom scores for sleep disturbance, cough, wheeze, and daily activities were similar during the three treatment periods if results were analysed using Friedman's non-parametric analysis of variance. However the Mantel-Haenszel test showed that sodium cromoglycate was superior to placebo (P less than 0.05) in maintaining normal daily activities. Either regimen is safe and well tolerated by young children. PMID:6791596

    Full Text Available Acute respiratory tract infections may trigger acute asthma attacks and may be held responsible for etiopathogenesis in children with asthma. Although bacterial infections attract a limited amount of attention, recently Chlamydia pneumoniae (CP and Mycoplasma pneumoniae (MP, in particular, are reported to be the possible factors. IgM and IgG seroprevalence was investigated in 66 children patients with bronchial asthma (between the ages of 3 and 14 for CP and Mycoplasma pneumoniae. In a total of 66 cases, 18 (27.2% patients were detected with IgG positivity for CP whereas 27 of them (40.9% were detected with IgG positivity for MP. IgG positivity was determined in 6 patients (13.0% in the control group for CP, and in 6 patients (10.8% in the control group for MP. The rate of the asthma patients with IgG seropositivity for MP was 4 times higher than that of the control group. It was seen that IgG antibody seropositivity for CP was higher in those with more frequent attacks. No such difference was observed in terms of IgG antibody seropositivity for M. pneumoniae. There are many studies indicating that CP and MP infections take an importance place in the etiology of bronchial asthma and asthma attacks in children. The results obtained reveal the effect of both microorganisms on the etiopathogenesis of the bronchial asthma and the increased number of asthma attacks.

    Full Text Available The purpose of this paper is to highlight the role of physical therapy in the field of respiratory pathology in children, mainly in bronchial asthma. By the hypothesis we want to prove that the intervention through physical therapy applied based on structured programs according to the needs of the subject and implemented by a specific methodology is able to optimize the functionality of asthmatic children. Material. The subjects of the study were three in number, aged 4-6 years, diagnosed with infantile asthma around the age of three years old. The experimental methods were selected based on objective clinical and functional assessment and intervention methods were chosen according with specific objectives, exemplifying respiratory exercises, games with objects and equipment, respiratory flow modulation techniques. Sessions were conducted three times a week totaling an amount of 36 sessions over three months. We obtained favorable results for all evaluated parameters, which were also influenced by the severity and number of occurrences of crises, the precocity of diagnosis and the moment when the treatment program started, the consistency of treatment sessions, the conditions of their entire activity and permanent collaboration between physician, physical therapist and parents. In conclusion, the experiment confirms the effectiveness of respiratory physiotherapy to optimize functionality in asthmatic children. Performing breathing exercises significantly reduces the occurrence of wheezing and improves effort capacity.

    It has been hypothesized that exhaled breath temperature (EBT) is related to the degree of airway inflammation/remodeling in asthma. The purpose of this study was to evaluate the relationship between the level of airway response to exercise and EBT in a group of controlled or partly controlled asthmatic children. Fifty asthmatic children underwent measurements of EBT before and after a standardized exercise test. EBT was 32.92 ± 1.13 and 33.35 ± 0.95°C before and after exercise, respectively (P < 0.001). The % decrease in FEV(1) was significantly correlated with the increase in EBT (r = 0.44, P = 0.0013), being r = 0.49 (P < 0.005) in the children who were not receiving regular inhaled corticosteroids (ICS) and 0.37 (n.s.) in those who were. This study further supports the hypothesis that EBT can be considered a potential composite tool for monitoring asthma.

    Full Text Available BACKGROUND: Acute exacerbations of bronchial asthma remain a major cause of frequent Emergency Department (ED visits by pediatric patients. However, other factors including psychosocial, behavioural and educational, are also reportedly associated with repetitive ED visits. Therefore, it is necessary to determine whether such visits are justifiable. OBJECTIVE: The objective of this cross-sectional study was to identify risk factors associated with visits to ED by asthmatic children. METHODS: Asthmatic children (n = 297 between 1-17 years old were recruited and information collected at the time of visiting an ED facility at two major hospitals. RESULTS: Asthmatic patients visited the ED 3.9 ΁ 3.2 times-per-year, on average. Inadequately controlled asthma was perceived in 60.3% of patients. The majority of patients (56.4% reported not receiving education about asthma. Patients reflected misconceptions about the ED department, including the belief that more effective treatments are available (40.9%, or that the ED staff is better qualified (27.8%. About half of patients (48.2% visited the ED because of the convenience of being open 24 hours, or because they are received immediately (38.4%. Uncontrolled asthma was associated with poor education about asthma and/or medication use. Patients educated about asthma, were less likely to stop corticosteroid therapy when their symptoms get better (OR:0.55; 95% CI:0.3-0.9; P = 0.04. CONCLUSION: This study reports that most patients had poor knowledge about asthma and were using medications improperly, thus suggesting inefficient application of management action plan. Unnecessary and frequent visits to the ED for asthma care was associated with poor education about asthma and medication use. Potential deficiencies of the health system at directing patients to the proper medical facility were uncovered and underline the necessity to improve education about the disease and medication compliance of patients and

    Background: The measurement of exhaled nitric oxide (NO) has recently been proposed as a useful technique for the evaluation of airway inflammation in asthma. The purpose of this study was to determine the effect of methacholine bronchial provocation on the levels of exhaled NO in asthmatic children. Method: Exhaled NO was measurement immediately before and after methacholine provocation in 51 children with mild to moderate asthma. Results: A significant decrease occurred in the level of exhaled NO (p<0.0001) after methacholine bronchial provocation which was not correlated with the percentage fall in forced expiratory volume in 1 second (FEV1). Conclusions: The methacholine test should not be used immediately before measurement of exhaled NO in children with asthma. PMID:12200520

    Full Text Available IntroductionChildren with severe asthma attack are a challenging group of patients who could be difficult to treat and leading to significant morbidity and mortality. Asthma attack severity is qualitatively estimated as mild, moderate and severe attacks and respiratory failure based on conditions such as respiration status, feeling of dyspnea, and the degree of unconsciousness. part of which are subjective rather than objective. We investigated clinical findings as predictors of severe attack and probable requirement for Pediatric Intensive Care Unit (PICU admission.Materials and MethodsIn a cross sectional and analytical study 120 patients with asthma attack were enrolled from April 2010 to April 2014 (80 admitted in the ward and 40 in pediatric intensive care unit. Predictors of PICU admission were investigated regarding to initial heart rate(HR, respiratory rate (RR, Arterial Oxygen Saturation(SaO2 and PaCo2 and clinically evident cyanosis.ResultsInitial heart rate(p-value=0.02, respiratory rate (p-value=0.03, Arterial Oxygen Saturation(p-value=0.02 and PaCo2(p-value=0.03 and clinically evident cyanosis were significantly different in two groups(Ward admitted and PICU admittedConclusion There was a significant correlation between initial vital sign and blood gas analysis suggesting usefulness of these factors as predictors of severe asthma attack and subsequent clinical course.

    Full Text Available Theophylline, (1,3-dimethylxanthine is widely used as a smooth muscle relaxant, myocardial stimulant and a diuretic agent. The most frequent use of theophylline is in treatment of acute and chronic asthma as a bronchodilator.To determine the effect of Theophylline on serum electrolyte and uric acid, 21 asthmatic children (age range 1,5-7 years with severe acute asthma and 25 patients with chronic asthma (5-15 years who were being treated with slow-release theophylline were enrolled in this study. Fifty age and sex matched normal children took part as control. Blood samples (5ml were withdrawn before, during and after completion of the course of intravenous theophylline treatment (0.05-0.70 mg/kg/ hr. Sera obtained were used for analysis of K+, Na+, phosphorus, calcium and uric acid by RA-1000 automated analyzer and the following results were obtained:(1 After treatment, total serum calcium in acute asthmatic patients decreased significantly compared with controls (PWe conclude that the serum levels of phosphate, potassium, calcium and uric acid should be monitored in patient receiving theophylline especially during prolonged use and critical emergency cases.

    Full Text Available There is growing evidence of a positive correlation between asthma and obesity in children and adults. Leptin and adiponectin regulate several metabolic and inflammatory functions. This study aims to evaluate serum leptin and adiponectin concentrations in asthmatic school children to investigate their association with obesity and the degree of asthma control. Obese asthmatic (OA and nonobese asthmatic (NOA children, aged 7 to 14, were randomly enrolled in this prospective study. Data on demographic, anthropometric, serum lipids, and spirometric measures and allergy status were collected and analyzed. Serum leptin was significantly higher (25.8±11.1 versus 8.7±11.1; P<0.0001 and adiponectin levels were lower (2.5±1.2 versus 5.4±2.9; P<0.0001 in OA compared to NOA children. The uncontrolled group had higher leptin and lower adiponectin levels compared to well and partially controlled asthma. BMI was positively correlated with leptin (r=0.79; P<0.001 and negatively with adiponectin (r=-0.73; P<0.001. Mean BMI and leptin levels were observed to be higher in girls compared to boys. Stepwise multiple linear regression analysis showed that higher BMI and female gender had significant effect on serum leptin levels. Among asthmatic children higher serum leptin and lower adiponectin levels were significantly associated with obesity and showed no significant association with degree of asthma controls.

    Tesfaye M Baye

    Full Text Available BACKGROUND: Candidate gene case-control studies have identified several single nucleotide polymorphisms (SNPs that are associated with asthma susceptibility. Most of these studies have been restricted to evaluations of specific SNPs within a single gene and within populations from European ancestry. Recently, there is increasing interest in understanding racial differences in genetic risk associated with childhood asthma. Our aim was to compare association patterns of asthma candidate genes between children of European and African ancestry. METHODOLOGY/PRINCIPAL FINDINGS: Using a custom-designed Illumina SNP array, we genotyped 1,485 children within the Greater Cincinnati Pediatric Clinic Repository and Cincinnati Genomic Control Cohort for 259 SNPs in 28 genes and evaluated their associations with asthma. We identified 14 SNPs located in 6 genes that were significantly associated (p-values <0.05 with childhood asthma in African Americans. Among Caucasians, 13 SNPs in 5 genes were associated with childhood asthma. Two SNPs in IL4 were associated with asthma in both races (p-values <0.05. Gene-gene interaction studies identified race specific sets of genes that best discriminate between asthmatic children and non-allergic controls. CONCLUSIONS/SIGNIFICANCE: We identified IL4 as having a role in asthma susceptibility in both African American and Caucasian children. However, while IL4 SNPs were associated with asthma in asthmatic children with European and African ancestry, the relative contributions of the most replicated asthma-associated SNPs varied by ancestry. These data provides valuable insights into the pathways that may predispose to asthma in individuals with European vs. African ancestry.

    The objective of this study was to determine the association of respiratory symptoms and medication use and exposure to various air pollutants, PM2.5 components, and source factors in a panel of asthmatic and nonasthmatic children in Santiago, Chile. To this end, 174 children (90 asthmatics and 84 nonasthmatics) were followed throughout the winter months of 2010 and 2011. During the study period, children filled out daily diaries to record respiratory symptoms and medication use. Air pollution data were obtained from government central site measurements and a PM2.5 characterization campaign. PM2.5 source factors were obtained using positive matrix factorization (PMF). Associations of symptoms and exposure to pollutants and source-factor daily scores were modeled separately for asthmatic and nonasthmatic children using mixed logistic regression models with random intercepts, controlling for weather, day of the week, year, and viral outbreaks. Overall, high concentrations of air pollutants and PM2.5 components were observed. Six source factors were identified by PMF (motor vehicles, marine aerosol, copper smelter, secondary sulfates, wood burning, and soil dust). Overall, single pollutant models showed significant and strong associations between 7-day exposures for several criteria pollutants (PM2.5, NO2, O3), PM2.5 components (OC, K, S, Se, V), and source factors (secondary sulfate) and coughing, wheezing and three other respiratory symptoms in both in asthmatic and nonasthmatic children. No associations were found for use of rescue inhalers in asthmatics. Two-pollutant models showed that several associations remained significant after including PM2.5, and other criteria pollutants, in the models, particularly components and source factors associated with industrial sources. In conclusion, exposure to air pollutants, especially PM2.5, NO2, and O3, were found to exacerbate respiratory symptoms in both asthmatic and nonasthmatic children. Some of the results suggest

Methods: A retrospective cohort study of 219 asthmatic patients (3-17 years old enrolled in Primary Care Services (PCSs in Embu das Artes (SP, from 2007 to 2011. Secondary data: gender, age, diagnosis of asthma severity, other atopic diseases, family history of atopy, and body mass index. To evaluate the clinical outcome of asthma, data were collected on number of asthma exacerbations, number of emergency room consultations and doses of inhaled corticosteroids at follow-up visits in the 6th and 12th months. The statistical analysis included chi-square and Kappa agreement index, with 5% set as the significance level. Results: 50.5% of patients started wheezing before the age of 2 years, 99.5% had allergic rhinitis and 65.2% had a positive family history of atopy. Regarding severity, intermittent asthma was more frequent (51.6% and, in relation to nutritional status, 65.8% of patients had normal weight. There was no association between nutritional status and asthma severity (p=0.409. After 1 year of follow-up, 25.2% of patients showed reduction in exacerbations and emergency room consultations, and 16.2% reduced the amount of inhaled corticosteroids. Conclusions: The monitoring of asthmatic patients in Primary Care Services showed improvement in clinical outcome, with a decreased number of exacerbations, emergency room consultations and doses of inhaled corticosteroids. No association between nutritional status and asthma severity was observed in this study.

    Full Text Available The Po Valley (Northern Italy has elevated levels of air-pollution due to various sources of pollution and adverse weather conditions. This study evaluates the short-term effects of exposure to particulate matter with a diameter of 10 microns or less (PM10 on asthma symptoms in school-aged children. An initial cross-sectional survey was conducted in the area to estimate asthma prevalence in children. Out of a total of 250 asthmatic children identified by the study, 69 agreed to participate in a panel study. The PM10 exposure assessment was based on a combination of geographic and environmental measurements leading to a focus on three different areas, each characterised by its own daily PM10 level. Participants were monitored daily for respiratory symptoms for eight weeks (January-March 2006. We assessed the relationship between daily PM10 exposure and occurrence of asthma symptoms with a generalised linear model based on a total of 3864 person-days of observation. Exposure to PM10 per m3 was found to be particularly associated with cough (OR=1.03, CI 95% 0.99; 1.08 and phlegm (OR=1.05, CI 95% 1.00; 1.10. In the most polluted area, exposure to PM10 was also associated with wheezing (OR=1.18, CI 95% 1.02; 1.37.

There was a universe of 72 asthmatic children from the number 32, 37, and 49 clinics of Palmira. For life quality estimation three questionnaires were used. We calculated the standard deviation and measure of the variables. The variations in measurement were evaluated through minimum change difference. Three measurements were realized in one month interval. Results: The 61.8% of patients evaluated with the American college quality test had bad life quality. The evaluation of life quality using the questionnaire of the Mc Master the Juniper University threw a moderate life quality, being the emotive sphere the most affected. The evaluation of life quality in caretakers showed a deterioration.

    The first asthma camp in Turkey was organized for one week in Iznik in September 1996. The camps were continued annually around the same time of the year in 1997, 1998, 2000, and in the consecutive years thereafter. The camp includes educational, sports and social activities. Children's knowledge about asthma and their attitudes towards physical and social activities were evaluated by a questionnaire. Pulmonary function tests were performed on the first and last day of the camp. There was no statistically significant difference between the mean spirometric values of the first and last day of the camp in spite of a vigorous physical and social program. Children enhanced their skills and knowledge about asthma and gained self-confidence in participating in sportive and social activities during the camp program. They did not experience any emergency room visit in the following year. In conclusion, a summer camping experience is very beneficial for asthmatic children in terms of both self-education and social and physical participation.

    Background: Concerns regarding the health impact of urban air pollution on asthmatic children are pronounced along the U.S.–Mexico border because of rapid population growth near busy border highways and roads. Objectives: We conducted the first binational study of the impacts of air pollution on asthmatic children in Ciudad Juarez, Mexico, and El Paso, Texas, USA, and compared different exposure metrics to assess acute respiratory response. Methods: We recruited 58 asthmatic children from two schools in Ciudad Juarez and two schools in El Paso. A marker of airway inflammation [exhaled nitric oxide (eNO)], respiratory symptom surveys, and pollutant measurements (indoor and outdoor 48-hr size-fractionated particulate matter, 48-hr black carbon, and 96-hr nitrogen dioxide) were collected at each school for 16 weeks. We examined associations between the pollutants and respiratory response using generalized linear mixed models. Results: We observed small but consistent associations between eNO and numerous pollutant metrics, with estimated increases in eNO ranging from 1% to 3% per interquartile range increase in pollutant concentrations. Effect estimates from models using school-based concentrations were generally stronger than corresponding estimates based on concentrations from ambient air monitors. Both traffic-related and non–traffic-related particles were typically more robust predictors of eNO than was nitrogen dioxide, for which associations were highly sensitive to model specification. Associations differed significantly across the four school-based cohorts, consistent with heterogeneity in pollutant concentrations and cohort characteristics. Models examining respiratory symptoms were consistent with the null. Conclusions: The results indicate adverse effects of air pollution on the subclinical respiratory health of asthmatic children in this region and provide preliminary support for the use of air pollution monitors close to schools to track exposure and

    In children unable to perform reliable spirometry, the interrupter resistance (R(int) ) technique for assessing respiratory resistance is easy to perform. However, few data are available on the possibility to use R(int) as a surrogate for spirometry. We aimed at comparing R(int) and spirometry at baseline and after bronchodilator administration in a large population of asthmatic children. We collected retrospectively R(int) and spirometry results measured in 695 children [median age 7.8 (range 4.8-13.9) years] referred to our lab for routine assessment of asthma disease. Correlations between R(int) and spirometry were studied using data expressed as z-scores. Receiver operator characteristic curves for the baseline R(int) value (z-score) and the bronchodilator effect (percentage predicted value and z-score) were generated to assess diagnostic performance. At baseline, the relationship between raw values of R(int) and FEV(1) was not linear. Despite a highly significant inverse correlation between R(int) and all of the spirometry indices (FEV(1) , FVC, FEV(1) /FVC, FEF(25-75%) ; P 12% baseline increase) with 70% sensitivity and 69% specificity (AUC = 0.79). R(int) measurements fitted a one-compartment model that explained the relationship between flows and airway resistance. We found that R(int) had poor sensitivity to detect baseline obstruction, but fairly good sensitivity and specificity to detect reversibility. However, in order to implement asthma guidelines for children unable to produce reliable spirometry, bronchodilator response measured by R(int) should be systematically studied and further assessed in conjunction with clinical outcomes.

    We examined the changes in arterial blood gas, FEV1 and V50 after the inhalation of procaterol on 19 occasions in 16 asthmatic children. The initial value of PaO2 had statistically significant correlation with the initial values of %FEV1 and %V50. PaO2 fell down in 11 out of 19 (57.9%) and remarkably decreased more than 5 mmHg in 6 out of 19 (31.6%). The fall in PaO2 was most significant at 5 min after the inhalation in almost subjects. The changes in PaO2 after the inhalation had good correlation with the initial value of %FEV1 and %V50. The initial values were quite lower in the patients with decreased PaO2 more than 5 mmHg than those with increased PaO2. Severe patients showed statistically low values of the initial PaO2 and %V50 and showed a fall in PaO2 after inhalation compared with moderate patients. An increase in A-aDO2 elicited that deteriorations of V/Q ratio caused a decrease in PaO2 after inhalation. There were no significant changes in heart rates and no complaints of nausea, headache or tremor.

    Full Text Available Introduction A prospective randomized study encompassed 100 patients with asthma in the stage of acute bronchial obstruction, 7 to 17 years of age, of both sexes and with the similar rate of attack seventy. The patients were spirometrically monitored (FVC, FEVl, PEF and FEF 25-75% by a pediatrician-pulmonologist for 12 days. Fifty patients were subjected to conservative drug therapy, whereas other 50 patients additionally underwent the Su Jok therapy according to the 6-Ki principles, applying laser ray at the acupuncture points in the hand. After 12 days of treatment the group, in which both therapy methods were applied, reached the range of referent values for all investigated parameters. In the same period of time the group undergoing only conservative drug therapy retained values below the reference ones for the given age for 3 (FEVl, PEFR and FEF 25-75% out of 5 investigated parameters. The obtained results differed from the group subjected to the combined therapy with the high rate of statistical significance. On the basis of the obtained results the efficacy of the 6-Ki technique of Su Jok therapy was confirmed as the therapeutic method supplementary to the conservative drug therapy in the treatment of acute bronchial obstruction in asthmatic children, provided that therapy is carried out in stationary conditions and under constant spirometric surveillance of the patient.

    Asthma and type I diabetes are major causes of chronic illness in childhood which, according to the current paradigm, have mutually antagonistic immunopathologies. Nonetheless, the disorders appear to preferably coexist both on population and individual levels. To assess whether children with asthma and type I diabetes might have a common immunoregulatory defect. The spontaneous and anti-CD3+ anti-CD28-stimulated cytokine production patterns by peripheral blood mononuclear cells of 13 children with both asthma and diabetes, nine children with diabetes, 11 children with asthma and nine healthy children were assessed using cytometric bead assay. The spontaneous production of IFN-gamma, TNF-alpha and IL-10 by mononuclear cells in children with both asthma and diabetes was elevated compared to the other study groups (p=0.02, p=0.001 and p=0.04, respectively). Stimulation in vitro increased IL-10 secretion in solely diabetic (p=0.008), asthmatic (p=0.008) and healthy children (p=0.01), but not in children with both diseases (p=0.22). Children suffering from both diabetes and asthma display a unique cytokine secretion pattern, distinct from those of solely diabetic, asthmatic and healthy children. In particular, these children appear to have a defect in regulation of IL-10 secretion.

    Full Text Available Objectives: The main goal of the study was to assess possible association between fetal exposure to fi ne particulate matter (PM2.5 and exhaled carbon monoxide (eCO measured in non-asthmatic children. Material and Methods: The subjects include 118 children taking part in an ongoing population-based birth cohort study in Kraków. Personal samplers of PM2.5 were used to measure fi ne particle mass in the fetal period and carbon monoxide (CO in exhaled breath from a single exhalation effort at the age of 7. In the statistical analysis of the effect of prenatal PM2.5 exposure on eCO, a set of potential confounders, such as environmental tobacco smoke (ETS, city residence area, sensitization to house dust allergens and the occurrence of respiratory symptoms monitored over the seven-year follow-up was considered. Results: The level of eCO did not correlate with the self-reported ETS exposure recorded over the follow-up, however, there was a positive signifi cant relationship with the prenatal PM2.5 exposure (non-parametric trend p = 0.042. The eCO mean level was higher in atopic children (geometric mean = 2.06 ppm, 95% CI: 1.58–2.66 ppm than in non-atopic ones (geometric mean = 1.57 ppm, 95% CI: 1.47–1.73 ppm and the difference was statistically signifi cant (p = 0.036. As for the respiratory symptoms, eCO values were associated positively only with the cough severity score recorded in the follow-up (nonparametric trend p = 0.057. In the nested multivariable linear regression model, only the effects of prenatal PM2.5 and cough severity recorded in the follow-up were related to eCO level. The prenatal PM2.5 exposure represented 5.1%, while children’s cough represented only 2.6% of the eCO variability. Conclusion: Our study suggests that elevated eCO in non-asthmatic children may result from oxidative stress experienced in the fetal period and that heme oxygenase (HO activity in body tissues may be programmed in the fetal period by the exposure to

    Full Text Available Background: Buccal health as integral and determinant part of general health makes us find different ways and methods to elevate life quality in the population. Objective: To establish the risk of suffering from dental cavities in asthmatic patients. Methods: A non match case and control study constituted by 100 children selected at simple random from the universe of asthmatic patients belonging to the General Comprehensive doctor offices number 7,9,10, 11, 43, and 44 from Area II in Cienfuegos municipality. The controlled group was selected in the same offices but from the universe of non asthmatic children. The age in both groups was from 6 to 15 years old. Visits to the children´s home were carried out for the record of the information through health oral dental and buccal health knowledge surveys. Results: The index of cavities, lost, and obturated permanent teeth was higher (3, 28 than in the control group (0, 44. The buccal hygiene indexes and the level of knowledge in both groups did not show significant differences. The most used drugs in asthma therapy were salbutamol and ketotifeno which change the buccal milieu. The odds ratio technique between asthmatic and non asthmatic patients showed 4, 9 times more at risk of suffering from dental cavities in the first group. Finally, it can be stated that the asthmatic patients are more at risk of suffering from cavities than the non asthmatic ones, so a program for buccal health in these patients should be performed.

    This study aimed to identify the relationship between fractional exhaled nitric oxide (FeNO) level and potential factors in non-asthmatic children from Shanghai, China. From March to April 2012, the school-aged children fulfilling the inclusion criteria were recruited. The FeNO levels of non-asthmatic children were detected by the Nano Coulomb nitric oxide analyzer. Questionnaires were recorded, including personal data, family illness history and daily habits. In addition, not only the number of leukocytes and eosinophils but also the level of hemoglobin in peripheral blood, were measured via the automated blood cell analyzer. All data were statistically analyzed with SPSS version 17.0 software and the correlation of these potential factors with FeNO level was calculated via Kendall's rank correlation. A total of 132 healthy children (aging 6-13 years) were enrolled in Minhang District, Shanghai, China. The mean value of FeNO level was 15.05 ppb. The correlation analyses revealed that age (R=0.190, p=0.029) and eosinophil number (R=0.575, p=0.000) were significantly and positively correlated with FeNO levels. The FeNO levels of individuals aged 10-13 years was significantly higher than those of the individuals aged 6-9 years (22.65 ± 18.82 ppb vs. 15.28 ± 9.78 ppb, p<0.05). However, other potential factors were not significantly correlated with FeNO level. The FeNO levels in healthy school-aged children may reflect airway eosinophilic inflammation levels, and was affected by eosinophil count and age significantly.

    Background Airway remodeling is the specific pathological characteristics of asthma, which is related to the clinical symptoms, pulmonary function, and airway hyperreactivity. This study aimed at exploring the effects of dermatophagoides pteronyssinus allergen-specific immunotherapy (SIT) on the serum interleukin (IL)-13 and pulmonary functions in asthmatic children.Methods Fifty-eight pediatric asthma patients allergic to dust mite participated in this study. Thirty-five children received SIT with a standardized dermatophagoides pteronyssinus extract for one year (SIT group), and the other 23 children treated with inhaled corticosteroids (ICS group) according to the Global Initiative for Asthma (GINA) for one year. Serum levels of IL-13, IL-4 and interferon (IFN)-y were examined and the pulmonary functions were checked before and after the treatment.Results After the treatment, the number of emergency visiting for asthma attack in SIT group was significantly less than that in ICS group. The serum levels of IL-4 and IL-13 were clearly reduced, IFN-γ and the ratio of IFN-γ/IL-4 were significantly increased, the pulmonary functions (forced vital capacity (FVC), forced expiratory volume in one second percentage (FEV1%) and peak expiratory flow percentage (PEF%) were significantly improved in the SIT group.Meanwhile, IFN-y and the ratio of IFN-γ/IL-4 were greatly increased, but serum levels of IL-4 and IL-13 had less changes,the pulmonary functions (FVC, FEV1% and PEF%) were poorly improved in ICS group. The basic pulmonary functions in both groups were at the same level, which had made more improvement in SIT group than in ICS group one year later.Conclusions One year of dermatophagoides pteronyssinus SIT can significantly reduce the frequencies of emergency visiting for asthma attack and improve the pulmonary functions of children with allergic asthma, and that is attributed to SIT, which can reduce the levels of IL-4 and IL-13 and regulate the imbalance of the

    The relation between air pollution and the exacerbation of childhood asthma was studied in a panel of 71 children (aged 5 to 7 yr) with mild asthma who resided in the northern part of mexico City. During the follow-up, ambient measures of particulate matter less than 10 microns (PM10, 24-h average) and ozone (1-h maximum) frequently exceeded the Mexican standards for these contaminants. The peak expiratory flow rate (PEFR) was strongly associated with PM10 levels and marginally with ozone levels. Respiratory symptoms (coughing, phlegm production, wheezing, and difficulty breathing) were associated with both PM10 and ozone levels. An increase of 20 micrograms/m3 of PM10 was related to an 8% increase in lower respiratory illness (LRI) among children on the same day (95% confidence interval [CI] = 1.04-1.15), and an increase of 10 micrograms/m3 in the weekly mean of particulate matter less than 2.5 microns (PM2.5) was related to a 21% increase in LRI (95% CI = 1.08-1.35). A 50 parts per billion (ppb) increase in ozone was associated with a 9% increase in LRI (95% CI = 1.03-1.15) on the same day. We concluded that children with mild asthma are affected by the high ambient levels of particulate matter and ozone observed in the northern part of Mexico City.

    Background and objective Asthma is a growing problem worldwide. Acute exacerbations impose considerable morbidity, mortality, and increased cost. Viral respiratory infections are the most common cause (80–85%) of pediatric asthma exacerbations and admissions to the hospital. The aim of this study was to determine the effect of a new synbiotic Lactocare® on viral respiratory infections and asthma exacerbations in asthmatic children. Methods In this double blind, placebo-controlled, randomized clinical trial, 72 children with mild persistent asthma, aged between 6 and 12 years, were randomized to receive either Lactocare®, a Synbiotic containing 1 billion CFU/Capsule of Lactobacillus casei, Lactobacillus rhamnosus, Streptococcus thermophilus, Bifidobacterium breve, Lactobacillus acidophilus, Bifidobacterium infantis, Lactobacillus bulgaricus, and Fructooligosacharide (Zist Takhmir, Tehran, Iran) or placebo daily for 60 days. The primary outcome was the number of viral respiratory infections, and secondary outcomes were school absence, salbutamol and prednisolone usage, outpatient visits, and hospital admission for asthma. The outcomes were compared among study groups using the SPSS 11.5 program and the Mann Whitney and Fisher exact tests. Results Of the 72 children who were enrolled with mild persistent asthma, 36 were assigned randomly to be treated with synbiotic and 36 with placebo. The number of viral respiratory infections was significantly higher in placebo group than the synbiotic group during the first month of intervention (0.74 ± 0.12 vs. 0.44 ± 0.1, p < 0.007) but not during the second month (0.5 ± 0.8 vs. 0.5 ± 0.8, p < 0.641). Considering the total duration of the study (two months), infection episodes also were significantly lower in the synbiotic group (0.92 ± 0.15 vs. 0.69 ± 0.11, p < 0.046). Salbutamol consumption was significantly lower in the synbiotic group, but there were no significant differences in school absenteeism, oral

    Full Text Available Abstract Background Childhood asthma in the Caribbean is advancing in prevalence and morbidity. Though viral respiratory tract infections are reported triggers for exacerbations, information on these infections with asthma is sparse in Caribbean territories. We examined the distribution of respiratory viruses and their association with seasons in acute and stable asthmatic children in Trinidad. Methods In a cross-sectional study of 70 wheezing children attending the emergency department for nebulisation and 80 stable control subjects (2 to 16 yr of age in the asthma clinic, nasal specimens were collected during the dry (n = 38, January to May and rainy (n = 112, June to December seasons. A multitarget, sensitive, specific high-throughput Respiratory MultiCode assay tested for respiratory-virus sequences for eight distinct groups: human rhinovirus, respiratory syncytial virus, parainfluenza virus, influenza virus, metapneumovirus, adenovirus, coronavirus, and enterovirus. Results Wheezing children had a higher [χ2 = 5.561, p = 0.018] prevalence of respiratory viruses compared with stabilized asthmatics (34.3% (24 versus (vs. 17.5% (14. Acute asthmatics were thrice as likely to be infected with a respiratory virus (OR = 2.5, 95% CI = 1.2 – 5.3.

    This study examines attitudes and factors affecting the decisions of pediatrics residents of both sexes toward having children during their residencies. In 1987, the authors surveyed by mail all 742 pediatricians who had trained at eight university-based residencies from 1981 to 1987; 417 responded. Of these, the men were significantly more likely than the women to have had children during their residencies (p less than .001). At the time of their residencies, 265 of these pediatricians were married. Of those who were married but did not have children during their residencies (175), the women were significantly more likely than the men to believe that having a child during residency would have had a negative influence on their careers (p less than .001) and would have been associated with difficulties in arranging child care (p less than .001). By contrast, among those pediatricians who were married and did have children during their residencies (90), their perceptions concerning the impacts on their careers of having children and the difficulty in arranging child care did not differ significantly by gender. The authors suggest that programs might explore the possibilities of greater flexibility in scheduling and of making child care more available so that residents could more easily combine their careers with having children.

    School-based services to improve asthma management need to be accompanied by public policies that can help sustain services, scale effective interventions, create greater equity across schools, and improve outcomes for children. Several national organizations, including the Centers for Disease Control and Prevention, have recommended specific public policies the adoption of which in school settings can improve asthma outcomes for children. Although many states and school districts have adopted some of these policies, adoption is not universal, and implementation is not always successful, leaving inequities in children's access to asthma services and supports. These issues can be addressed by changing public policy. Policy change is a complex process, but it is one that will benefit from greater involvement by asthma experts, including the researchers who generate the knowledge base on what services, supports, and policies have the best outcomes for children. Asthma experts can participate in the policy process by helping to build awareness of the need for school-based asthma policy, estimating the costs associated with policy options and with inaction, advocating for the selection of specific policies, assisting in implementation (including providing feedback), conducting the research that can evaluate the effectiveness of implementation, and ultimately providing information back into the policy process to allow for improvements to the policies.

    The paediatric asthma guidelines have been successful in providing a uniform approach to the management of asthma for the medical profession as a whole. Unfortunately, the guidelines were generated without input from patients themselves and consequently do not consider issues that are important to patients such as a preference for oral treatment. Asthma is a heterogeneous group of conditions and the guidelines do not sufficiently define subgroups of patients and their particular needs. As a result, there has been a tendency to assume that all wheezing in infancy is asthma and this had led to gross overtreatment in certain patients. In contrast, severe asthma often remains underdiagnosed and undertreated. The most recent revision of the guidelines has classified asthma in terms of the patterns of disease; infrequent episodic, frequent episodic and chronic persistent. The treatment required for each of these groups is clearly defined and there is no need for stepwise therapy. Other changes to the guidelines will occur and are needed. None of the treatments available can modify the natural history of asthma; they control the symptoms not the disease process. Evidence from bronchial biopsies suggests that both inflammation and remodelling occur early, even before the first symptoms appear. We need to look for the factors in early life that predict which children will go on to develop asthma and intervene at that stage. Anti-histamines and leukotriene receptor antagonists may be interesting as interventions in that respect. Two important unresolved issues are to understand what drives remodelling and inflammation, and to look at early life origins of asthma. These approaches may provide effective therapeutic targets and, ultimately, a means of prevention.

    The main goal of the study was to test the hypothesis that prenatal and postnatal exposure to polycyclic aromatic hydrocarbons (PAH) is associated with depressed lung function in non-asthmatic children. The study sample comprises 195 non-asthmatic children of non-smoking mothers, among whom the prenatal PAH exposure was assessed by personal air monitoring in pregnancy. At the age of 3, residential air monitoring was carried out to evaluate the residential PAH exposure indoors and outdoors. At the age of 5 to 8, children were given allergic skin tests for indoor allergens; and between 5–9 years lung function testing (FVC, FEV05, FEV1 and FEF25–75) was performed. The effects of prenatal PAH exposure on lung function tests repeated over the follow-up were adjusted in the General Estimated Equation (GEE) model for the relevant covariates. No association between FVC with prenatal PAH exposure was found; however for the FEV1 deficit associated with higher prenatal PAH exposure (above 37ng/m3) amounted to 53 mL (p = 0.050) and the deficit of FEF25–75 reached 164 mL (p=0.013). The corresponding deficits related to postnatal residential indoor PAH level (above 42 ng/m3) were 59 mL of FEV1 (p=0.028) and 140 mL of FEF25–75 (p=0.031). At the higher residential outdoor PAH level (above 90 ng/m3) slightly greater deficit of FEV1 (71mL, p = 0.009) was observed. The results of the study suggest that transplacental exposure to PAH compromises the normal developmental process of respiratory airways and that this effect is compounded by postnatal PAH exposure.

    To explore the use of oscillometry as a measure of airway responsiveness, 69 asthmatic children underwent histamine and methacholine bronchoprovocation using dosimeter-MedicAid (Jaeger Co.; Germany) and DeVilbiss nebulizers (DeVilbiss, Bornemouth; England). The mean increase in R5 resistance in challenge testing measured after methacholine with the dosimeter-MedicAid nebulizer was 77.14% compared with 65.05% using histamine. Using the dosimeter-DeVilbiss nebulizer, the mean increases in R5 resistance following methacholine and histamine testing were 57.50% and 59.36%, respectively. The resistance R5 over R20 significantly correlated with forced expiratory volume in 1 second (FEV1). The MedicAid produced a more aggressive challenge than the DeVilbliss nebulizer. Oscillometry can be used to monitor the level of airway hyperresponsiveness following bronchoprovocation tests.

    1. 40 children with Asthma bronchiale under long-term Cortisone therapy were admitted as in-patients of a clinic in the climate of the Northsea. 37 children needed Cortisone therapy because of serious attacks of Asthma bronchiale, and 3 children because of disturbing neurodermitis constitutionalis. -- 2. Corticoids were discontinued abruptly, immediately after admission. a) In 34 children the discontinuation had no adverse effect the following 6 to 8 weeks, or even longer, there was no need for Cortisone therapy. b) In 4 children during the first 2 weeks and in 2 further children during the 5th or 6th week, the asthmatic disorder deteriorated to such a degree that Cortisone therapy had to be re-introduced. -- 3. On the base of the reported observation, it is concluded that under the conditions of the Northsea climate it is of advantage for children with Asthma bronchiale and Neurodermitis to discontinue abruptly Cortisone therapy because a) this type of therapy which involves the potential risk of unwanted side effects can be shortened and b) the specific positive effect of climatic changes during the first couple of weeks is utilized to a greater extent. The gradual reduction of steroid therapy would diminish this particular stimulation. However, this kind of treatment requires close clinical observation to anticipate an acute "Addison-Crises". -- 4. All children with serious dispuce already during the first days of their stay in the clinic clearly need continuation of steroid therapy. -- Otherwise, even previous steroid therapy for more than one year is no contradiction for the recommended procedure as long as the clinical condition of the patient allows for it.

    Full Text Available BACKGROUND: A rich microbial environment in infancy protects against asthma [1], [2] and infections precipitate asthma exacerbations [3]. We compared the airway microbiota at three levels in adult patients with asthma, the related condition of COPD, and controls. We also studied bronchial lavage from asthmatic children and controls. PRINCIPAL FINDINGS: We identified 5,054 16S rRNA bacterial sequences from 43 subjects, detecting >70% of species present. The bronchial tree was not sterile, and contained a mean of 2,000 bacterial genomes per cm(2 surface sampled. Pathogenic Proteobacteria, particularly Haemophilus spp., were much more frequent in bronchi of adult asthmatics or patients with COPD than controls. We found similar highly significant increases in Proteobacteria in asthmatic children. Conversely, Bacteroidetes, particularly Prevotella spp., were more frequent in controls than adult or child asthmatics or COPD patients. SIGNIFICANCE: The results show the bronchial tree to contain a characteristic microbiota, and suggest that this microbiota is disturbed in asthmatic airways.

    Full Text Available Research that focuses on children who migrate without a parent or legal guardian is most often carried out in low-income countries. Such migration is increasingly associated with child trafficking. In this article the Icelandic custom to send children to the country during the summer months in the last century will be examined. It is based on secondary documents such as journals, magazines, documents and reports from child protection authorities. The Icelandic population shared the opinion that seasonal rural residence for urban children was beneficial for the nation, the family and the child. In the country, the children would enjoy unspoiled nature, clean mountain air and nutritious food. In addition, they would learn to attend animals and proper work. Individuals, associations, charities and child protection authorities collaborated in an effort to organise rural residence for children during the summer months, either at farms or particular summer camps. Rural residence was considered to be particularly important for delinquent children, but also those who suffered from poverty, irresponsible parental behaviour and poor health. Data is lacking on the number of children sent to the country and their experiences however it is known to have varied greatly. Likewise, little is known about the considerations of the farmers who hosted the children and the children’s parents. This custom is typically per definition child migration without a parent or legal guardian. Care should be taken not to classify such customs routinely as child trafficking wherever they are practiced.Rannsóknir á búferlaflutningi barna til lengri eða skemmri tíma án samfylgdar foreldris eða löggilds forráðamanns beinast oftast að börnum sem flytja úr einum stað í annan innan eða milli lágtekjulanda.

    Full Text Available Objective: To evaluate the efficacy of superoxide dismutase (SOD in lung function (FEV1 reversibility and respiratory symptoms (drug scores, symptoms scores in asthmatic and house dust mite allergic children receiving house dust mites immunotherapy. Methods: Forty subjects aged 6–17 years old with asthma, tested positive for house dust mite allergy on skin prick test, and received immunotherapy were enrolled in this study. All subjects completed clinical based assessments and diary-based assessments for drug and symptom scores. Following a four-week baseline assessment, all subjects were randomized to receive SOD or placebo. Respiratory symptoms (drug and symptoms score and FEV1 were evaluated at the end of the 1st, 2nd, 3rd, and 4th weeks after randomization. Drug score, symptoms score, and FEV1 reversibility test results were analyzed using a Paired t test and repeated measure of ANOVA. Results: There was a significant difference in drug scores, symptoms score, and FEV1 reversibility test outcomes between SOD and placebo. SOD group showed a significant decrease in all outcome measures compared to those in placebo group. Conclusions: The use of SOD as antioxidants is effective in accelerating symptom relief for children with asthma and house dust mite allergy receiving house dust mite immunotherapy.

  18. [Physical activities and sports in asthmatic patients].

    Asthma patients are too often advised to refrain from sport. Enforced sedentariness, especially in children, leads to muscle hypotonia, reduced mechanical efficiency, paramorphisms, and adverse psychological consequences. Not all asthmatics develop airway spasm as a result of exercise. On the other hand, there are subjects whose bronchial hyper-reactivity is stimulated solely by muscular effort. The pathogenesis of exercise-induced bronchospasm is not fully understood. In any event, numerous studies have demonstrated the beneficial and even therapeutic effect of physical exercise and sport in cases of asthma. Provided they are practised with judgment and in accordance with a suitable programme, swimming, activities of an alternating aerobic and anaerobic type, cross-country skiing, gymnastics, and fencing are primarily indicated. Some asthmatics have also won Olympic medals. In the light of the studies carried out so far, it is strongly suggested that asthmatics be encouraged to take up sport suitable to their psychophysical characteristics, and not kept wrapped up in cotton wool.

    Objective To investigate the prevalence of allergens in asthmatic children in Haikou. Methods A total of 10 241 children of 0~14 years old were involved and investigated by cluster sampling, in which 324 children were diagnosed as asthma. Allergic sensitization was studied with questionnaire, skin prick tests and specific IgE mea-surements. Results Among the 324 asthmatic children, 224 (69.1%) had allergy history, including 91 cases (28%) of ec-zema, 64 cases (19.8%) of food allergy, 28 cases (8.6%) of drug allergy, 18 cases (5.6%) of cigarette smoke allergy, 19 cases (5.9%) of decoration smell allergy, 13 cases (4.0%) of pet allergy, 11 cases (3.4%) of cooking oil smell allergy, and 9 cases (2.8%) of pollen allergy. A total of 269 asthmatic children (83.0%) showed SPT positive reaction, with 292 cases (90.1%) of Dermatophagoides pteronyssinus (Der p), 289 cases (89.2%) of Dermatophagoides farina (Der f), 277 cases (85.5%) of Blomia tropicalis (Blo t), 64 cases (19.6%) of cockroach, 11 cases (3.4%) of mould, 11 cases (3.4%) of pol-len, 38 cases (11.7%) of cat dander, and 82 cases (25.3%) of dog dander. The specific IgE-positive rate to inhaled aller-gens was 72.2%(235 cases), with 69.8%(226 cases) to mites, which was the highest. The specific IgE-positive rate to food allergens was 28.7%(93 cases), with 25.3%(82 cases) to milk, 9.9%(32 cases) to egg white, 22.8%(74 cases) to crab and shrimp, 9.0%(24 cases) to tropical fruit, and 8.3%(27 cases) to fish. Comparison of inhaled allergen specific IgE-positive rate between different age groups showed that, the positive rate to dust mites, cockroach was significantly higher in 3~7 years old group than 0~3 years old group old, and the positive rate to dust mites, cockroach, dog dander, cat dander was higher in 7~14 years old group than 0~3 years old group. Conclusion House dust mites and Blomia tropicalis are the major allergen sources among asthmatic children in Haikou. Dog dander, cat dander and cockroach are also

    During 2001 to 2004, a study was conducted to assess the indoor environmental and health impact of installing allergen-reducing interventions in the homes of asthmatic children. Based on the results of a pilot study, to determine an intervention that would provide improved symptom scores and a reduction in house dust mite allergen (Der p 1), mechanical ventilation and heat recovery (MVHR) systems were installed in 16 homes. Environmental and respiratory health assessments were conducted before and after the installation of the MVHR systems. The results indicated that the installation of MVHR systems reduced Der p 1 concentrations in living room carpets and mattresses. There were significant reductions in symptom scores for breathlessness during exercise, wheezing, and coughing during the day and night. Although, there was not a parallel control group for the main study, the lack of change in the pilot study control group (who did not receive an intervention), indicated that the changes in symptom scores were in part to do with the intervention. Larger scale trials are needed to determine the efficacy of MVHR systems in homes to improve indoor air quality and reduce asthma symptoms.

To determine the relationship of management behaviors of parents with different levels of self-regulation and main asthma outcomes. Methods Using a cross-sectional design, a total of 151 parent-child pairs completed take-home questionnaires were analyzed. Results Main findings revealed that external resources, self-efficacy and self-regulation were significant predictors of parental use of daily prevention and parental reported medication adherence. Parental management behaviors were found to be moderately related to main asthma outcomes. The more parents used management strategies, the better physical and school performance and the higher quality of life their children had. Trend analysis of family phase differences revealed a significant positive linear correlation between children's pulmonary functioning and quality of life. Conclusions Intervention focused on parental self-efficacy and self-regulation can improve the quality of life of asthmatic children in primary school children.

Levou-se a efeito três estudos de caso com crianças participantes de um Programa de Educação em Asma, utilizando uma abordagem cultural que usa as narrativas como um meio de buscar significações. Foram realizadas observações no ambiente hospitalar e entrevistas com mães. Usou-se as narrativas do brincar, já que este permite ampliar o estudo da subjetividade infantil. A análise das narrativas fundamentaram-se no modelo estrutural de Todorov e os resultados evidenciaram que as narrativas no brincar apresentam uma estrutura peculiar, explicada pelas particularidades psíquicas destas crianças. Elementos da cultura estiveram presentes nas narrativas, permitindo a análise de como a criança negocia seus significados pessoais e familiares com os significados da cultura médico-hospitalar.

    This study was conducted to evaluate the comparative effectiveness of two different asthma educational programs. One was self-management asthma education based on the PRECEDE-PROCEED model to change the influential factors based on a previous need assessment study in Taiwan. The other consisted of regular outpatient asthma education. The purposes were: 1) to compare differences in the asthma knowledge, self-efficacy, perceived effectiveness, children's cooperation, doctor-patient communication, and self-management behaviors in the experimental and control groups before education, and 2 weeks, 3 months, and 6 months after education; and 2) to compare differences in drug use, medication utilization, asthma severity, signs/symptoms of asthma, school absenteeism, and exercise ability before education, and 2 weeks, 3 months, and 6 months after education. Parents of asthmatic children were recruited from among outpatients of Chang Gung Children's Hospital, Taoyuan, Taiwan. They were grouped by registration number: those with even numbers were assigned to the experimental group, and those with odd numbers were assigned to the control group. Measurements were collected four times from all parents by means of a questionnaire and chart review. The General Linear Model: Repeat Measurement was used to compare variance differences. The following results were found. 1) Asthma knowledge, self-efficacy, perceived effectiveness, children's cooperation, and self-management behaviors significantly improved after the self-management asthma educational program based on PRECEDE-PROCEED. Except for perceived effectiveness, all variables still had good effectiveness after 6 months of follow-up. The experimental group was better than the control group in knowledge, children's cooperation, and self-management behaviors at the 3-month follow up, as well as in knowledge and children's cooperation at the 6-month follow-up. 2) In both the experimental and control groups, the educational program

    Objective To investigate the prevalenve of common inhaled allergens in asthmatic children in Hainan for exploring an effective management of allergen avoidance and providing a basis in the promotion of specific immunotherapy. Methods The skin prick test (SPT) with a panel of 13 allergen extracts was undertaken in 2 361 children with asthma, and 450 cases of them futher received specific IgE test against 10 allergens. Results The results of the SPT showed that 86% of the patients were sensitized to at least one allergen extract, and consisting of 91.2% for Dermatophagoides pteronyssinus (Der p), 89.3% for Dermatophogoides farinae (Der f) and 86.3% for Blomia tropicalis (Blo t), respectively. The pereentage of strong SPT positive eases (> 3 class) against three kinds of mites was 65.7% for Der p, 65.4% for Der f and 58.2% for Blo t, respectively. Furthermore, the SPT positive rates for animal dander in children with asthma were 22.4% for dog dander, 14.4% for cat dander, 28.7% for German cockroach, and 21.9% for America cockroach, respectively. However, the positive levels to these alergens were generally low. The positive rate of the specific IgE test in 450 children with asthma was 72.4%, and consisting of 66.2% for Der p and 59.6% for Der f. Conclusions There is a very high prevalence of the sensitization against Der p, Der f, and Blo t,and the sensitization against animal dander including dog, cat and cockroach is also found in a certain proportion in Hainan, that will be significant to avoid allergens and to promote the specific immunotherapy in asthmatic children in Hainan.%目的 了解海南地区儿童哮喘常见吸入性变应原,探讨有效实施变应原避免的措施,为成功开展特异性免疫治疗提供依据.方法 对2 361例哮喘儿童进行13种常见过敏原皮肤点刺试验,对其中450例患儿进行10种过敏原体外特异性IgE检测.结果 2 361例哮喘患儿皮肤点刺阳性率为86.0%,其中,屋

Results were analyzed using Pearson's coefficient. RESULTS: Correlations between absolute and percentage PEF figures and clinical severity score, were negative and very close to zero, signifying a weak correlation with no statistical significance. The same relationship was observed between VEF1 and clinical severity score. The correlation between VEF1 and PEF had a positive value with statistical significance (p = 0.000. CONCLUSIONS: Since the best parameter for evaluating airway obstruction is VEF1, the finding that there is a positive correlation between this measure and absolute PEF reinforces the importance of its use and allows for the recommendation that PEF be measured as part of the management of asthmatic children, particularly in severe cases.

    nested in a cohort of 4,757 pregnant women. A total of 86 six-year-old children were evaluated, born to mothers with a medical diagnosis of asthma before pregnancy. Information was collected regarding clinical symptoms of atopy and respiratory diseases, as well as socioeconomic and exposure variables; the children were submitted to spirometry. RESULTS: Spirometric alterations were observed in 30.3% of cases, with a prevalence of asthma in those who had an obstructive pattern. 9.3% of the children had a previous medical diagnosis of asthma; however, the established diagnosis based on the presence and frequency of asthma symptoms was 18.6%. Of the 86 participating children, 37.2% had a score of five or more points in the International Study of Asthma and Allergies in Childhood (ISAAC questionnaire, which was associated with spirometry alterations (p = 0.002. After multiple logistic regression analysis, higher paternal education, higher number of bedrooms in the family's home, and mother who did not have "wheezing" episodes during pregnancy were statistically significant as protective factors for the presence of respiratory disorder detected by spirometry. CONCLUSIONS: The frequency of spirometry alterations in children of asthmatic mothers was high; the restrictive pattern was more often observed that the obstructive. There was a higher incidence of obstructive test results in those who presented clinical symptoms of asthma, with a higher frequency of clinical diagnosis of asthma than that found in the literature.

  17. Long-term trends of men's co-residence with children in England and Wales

    Full Text Available Background: Increasing numbers of childless men as well as fathers with reduced or no contact with their children have sparked concern about an erosion of fatherhood. Although the general trend is undisputed, claims about men's decreasing family involvement lack a sound empirical basis that enables comparisons between countries and sub-groups of society. Objective: This study derives long-term trends in father-child co-residence over the life course in England and Wales, and provides comparisons of these trends by level of education and ethnic origin. Methods: The paper calculates shares of father-child co-residence from the National Statistics Longitudinal Study (LS and the British Labour-Force Surveys (LFS. Results: There has been a decline of father-child co-residence in England and Wales for men in their thirties, an even greater decline for men in their twenties, and a small increase in the shares of father-child co-residence at higher ages. The trends for different educational groups were similar, but men with a degree had particularly low rates of father-child co-residence at younger ages, and relatively high ones at older ages. Neither less-educated men, nor men from Black-Caribbean and Black-African origins showed rates of father-child co-residence as low as one might have expected. Conclusions: The steady decline of father-child co-residence among men born between 1930 and 1979 in England and Wales lends support to claims about an erosion of fatherhood. However, it is unwarranted to generalize findings from other countries about particularly low levels of father-child co-residence among less-educated men to men in England and Wales.

    Objective To analyze the change of cysteinyl leukotriene ( Cys-LTs) levels and 8-Isopros-tane (8-iso-PG) levels in the exhaled breath condensate (EBC) of asthmatic children from acute exacerbation to clinical remission, and investigate the role of the detection of Cys-LTs and 8-iso-PG in EBC in its severity and pathogenesis , and explore the relationship between the Cys-LTs and 8-iso-PG through measuring Cys-LTs levels and 8-iso-PG levels in the EBC of asthmatic children. Methods The outpatient or inpatient asthmatic children of the pediatrics and a group of healthy children were studied. All subjects′ EBC were collected by the R-Tube produced by American Respiratory Research. The concentration of Cys-LTs and 8-iso-PG in EBC were measured by enzyme-linked immunosorbent assay (ELISA), and compared among children in asthmatic exacerbation, asthmatic remission, and healthy condition. The relevance of their change would be explored at the same time. Results (1) Cys-LTs levels in EBC were higher in asthma exacerbation, compared to healthy controls (P0. 05 ) . ( 2 ) 8-iso-PG levels was higher in asthmatic exacerbation compared to asth-matic remission ( P0.05)。(2) EBC中的8-iso-PG水平发作组较缓解组高( P<0.05);缓解组较健康对照组高( P<0.05)。(3)对三组EBC中Cys-LTs和8-iso-PG分别进行相关性分析,发作组中Cys-LTs与8-iso-PG有显著相关性( n1=35, r1=0.61, P<0.05),缓解组中两者无显著相关性。结论哮喘患儿EBC中8-iso-PG水平与哮喘严重程度有关,可作为疗效监测的客观指标。 Cys-LTs水平与哮喘恶化有关。两种标志物在哮喘发作时有相关性,提示此时气道氧化应激与炎症反应有一定关联。

    358 asthmatic children in our asthma clinic observed from October 2007 to August 2009 were divided into different groups as asthma attack group and non-attack group, and treatment group and non-treatment group. The therapy, attack symptoms and signs of them were recorded into clinical form. Tests of spiromety and FENO were performed at the same time. Results FENO in asthmatic children was 28.5( 15.5 ~ 55.0) × 10-9, there being no significant difference between male and female. FENO in asthmatic children older than 11 years was significantly higher than in normal children[36.0 (20.0 ~ 65.0) × 10-9,12.6(9.5 ~ 17.1 ) × 10-9, Z = -11.352, P < 0.001 ]. FEN O in asthmatic children was positively correlated with age (r = 0.206, P < 0.01 ), not related to asthma history course or FVC, but slightly negatively correlated with FEV1 and MMEF(r = -0.164,P < 0.0l,r = -0.176,P < 0.01). FENO in the group of asthma attack was significantly higher than the group of non-asthma attack [ 38.4 ( 16.7 ~ 59.1 ) × 10-9, 26.0 ( 15.0 ~ 51.0 ) × 10-9;Z = -2.327, 0.01 < P < 0.05] ;in the group of treatment it was significantly lower than in the non-treatment group [24.0( 13.0 ~ 48.5) × 10-9,31.0 (16.7 ~ 57.2) × 10-9, Z = -2.215,0.05 > P > 0.01]. By analysis with ROC in children older than 11 years, the cut-off point was 17.9 × 10-9, sensitivity was 0.802, specificity was 0.825. Seventy-seven out of the 96 asthmatic chil dren with normal lung function showed higher FENO and 15 out of them had asthma attack. Conclusion It is found that FENO in asthmatic children is significantly higher than in normal children. FENO is a useful method to identify non-specific inflammation in asthmatic children from the normal children. The patients who have asthma attack or non-treatment ones have a higher FENO. Higher FENO indicates bad control or even worse condition. Patients who have no symptoms but normal lung function still have abnormal FENO. The test of FENO can be used

    Full Text Available Objective: The objective was to find the prevalence of dental fluorosis among school children residing in Kanpur city, Uttar Pradesh India. Materials and Methods: A total of 1343 school children, residing in the city since childhood and consuming the groundwater, in the age group of 7-17 years was selected from various schools. Schools were selected from all four directions of the city. Children were categorized in five age groups and were examined for dental fluorosis. Dean′s criteria for assessment of dental fluorosis were used, and observations were recorded on a study specific performa. Results: Among the 1343 children examined, 243 (18% were found to be having dental fluorosis, among which number of males (131 was more than females (112. Among the different grades of fluorosis observed, mild dental fluorosis was observed in most of the cases (158. It was observed that the southern part of the city had a maximum number of cases of dental fluorosis. Conclusion: It was evident from the results that the city had a good number of cases of dental fluorosis and that the groundwater in certain areas had more than normal quantity of fluoride. Since this study was the first attempt in this area, more studies can be undertaken to substantiate our findings.

    Despite extensive studies of neighborhood effects on children׳s outcomes, there is little evidence on rural-urban impacts on child mental health. We modeled trajectories of emotional-behavioral problems of white majority children at ages 3, 5, and 7 in England in areas with varying levels of rural and urban settlement, using the Millennium Cohort Study. After adjusting for area selection, children in less sparse rural areas had fewer conduct and peer problems, and children in areas with a mix of rural and urban settlement had fewer emotional symptoms, explained by the quality of their schools. Area differences remained in emotional problems.

    Full Text Available Objective: Nutritional status directly affects the growing up of children in terms of physical and mental development. In the urban slums the underprivileged children lag behind the basic necessary amount of food and nutrition which is likely to lead to their ill development. This study was undertaken to investigate the dietary food intake pattern among urban slum dwelling children attending schools Dhaka city and to examine the association with various social factors.Material & Methods: This study is a cross-sectional study among 396 school going children who are residents of slums in different parts of Dhaka Metropolitan city.Findings: The age of the children were categorized into three age groups; Mean age for the children of age group-1 was 6.51 (±1.01 years, for the age group-2 was 9.24 (±1.09 years and for the age group-3 was 12.5 (±0.91 years. In 77.8 % of the cases the child gets three meals per day but inadequate in amount. In most of the cases the common foods were rice, lentil, potato and green leafy vegetables. The food frequencies reported by the children were; eggs: 1.4 times per week, milk: 1.2 times per week, meat: 0.4 times per week, fish: 2.8 times per week and fruits 2.9 times per week. Those children from families with lower incomes and less educated parents had a dietary pattern which tended to be poor regarding egg, milk, meat and fruit.Conclusion: The diets of these urban slum school children were inadequate for macronutrients and micronutrient, which is a danger for significant nutritional and health implications. The need to develop healthy food supply and habits should be emphasized.

    Full Text Available Asthma is considered to be the most common respiratory disorder complicating pregnancy. Seventy-six asthmatic and 152 non-asthmatic pregnant women were studied. Maternal asthma was significantly associated with adverse infant outcomes, including prematurity, low birth weight and the need for Cesarean delivery. The results of this study could indicate that pregnant women with asthma were at substantially increased risk for adverse infant outcomes and suggest the need for extra attention to mothers with asthma before and during pregnancy.

    Full Text Available The basic needs of the children of the Residence Juan de Lanuza (Zaragoza, Spain are covered by the daily amount of food they are provided with at meals. However, the tasks of the professionals who work in this Home are not restricted to feeding. One of the educational goals is to teach children socially adapted food habits, which are considered essential for the young persons’ “culturisation”. Food socialization has its roots in the ideology of the educating staff. The disciplinary system is based on the containment of deviations from normative food habits. The harshest punishment is inflicted when the child refuses to eat. The aim of this paper is to show that the resistance to food offered by the children of this Home between 6 and 12 years of age, is not due to lack of appetite but is the expression of a specific demand. Through their behaviour the children make explicit their wish to belong to a certain age group, they assert their ethnic difference, they show whether they wish to relate or not to other children or the staff, they ask for the educator’s attention to their state of mind, etc.

    Full Text Available Abstract Background The aim of this retrospective cohort study was to record the prevalence of overweight and obesity in relation to parental education level, parental body mass index and region of residence, in preschool children in Greece. Methods A total of 2374 children (1218 males and 1156 females aged 1–5 years, stratified by parental educational level (Census 1999, were examined from 105 nurseries in five counties, from April 2003 to July 2004, Weight (kg and height (cm were obtained and BMI (kg/m2 was calculated. Both the US Centers for Disease Control (CDC and the International Obesity Task Force (IOTF methods were used to classify each child as "normal", "at risk of overweight" and "overweight". Parental demographic characteristics, such as age and educational level and parental anthropometrical data, such as stature and body weight, were also recorded with the use of a specifically designed questionnaire. Results The overall estimates of at risk of overweight and overweight using the CDC method was 31.9%, 10.6 percentage points higher than the IOTF estimate of 21.3% and this difference was significant (p Conclusion Both methods used to assess prevalence of obesity have demonstarted that a high percentage of the preschool children in our sample were overweight. Parental body mass index was also shown to be an obesity risk factor in very young children.

    Objective To investigate the effect of parental management and cognition of related knowledge on asthmatic children's compliance to therapy. Methods A total of 86 cases of asthmatic children admitted to Department of Pediatrics of our hospital from October 2013 to October 2015, were selected as research objects. Clinical data of these children were collected and a questionnaire was developed. Based on the behavior of children with glucocorticoids dur-ing treatment, all these children were divided into the compliance group (34 cases) and the non-compliant group (52 cas-es). The general information questionnaire, parental knowledge, parental management, medication compliance question-naires and drug inhalation technique questionnaire survey were compared with statistical methods. Results General in-formation on two groups of children and parents showed that the compliance group of children had the lower frequency of outbreak and better educated parents (P<0.05). The cognition score of disease in the compliance group parents was (18.6 ± 2.6) points, significantly higher than the non-compliant group of (12.5 ± 2.1) points (P<0.05). The management score of in the compliance group parents was (119 ± 7) points, significantly lower than the control group of (145 ± 8) points (P<0.05). The children's inhalation technology score of in the compliance group was (5.2±0.8) points, significant-ly higher than that in the control group of (2.1 ± 1.3) points (P<0.05). Logistic regression analysis showed that parental cognition [OR=1.04, 95% CI (1.00~1.13), P=0.02], parental management [OR=0.06, 95%CI (0.50~0.92), P=0.01] and children with inhalation technique [OR=2.68, 95% CI (1.52~6.53), P=0.01] were the influencing factors of treatment compliance in asthmatic children (P<0.01). Conclusion To improve parents' cognition and management can improve medication compliance and symptoms of children with bronchial asthma, and reduce the incidence frequency.%目的:探讨父母认

    Full Text Available Abstract Background Global warming and the established responsibility of the anthropogenic emissions of greenhouse gases represent a strong push towards the construction of new nuclear power plants (NPPs to cope with the growing energy needs. The toxicity of nuclear waste associated with the extreme difficulty of their disposal and increase in cancer mortality and incidence following occupational radiation exposure are considered the only health problems. Methods A search of scientific articles and government documents published since January 1, 1980 to July 1, 2010 was performed to evaluate cancer rate and mortality in residents, particularly children, in the vicinity of NPPs. Results A recent well conducted state-of-the-art case-control study of childhood cancers in the areas around German NPPs (KiKK study showed a statistically significant cancers (2.2-fold increase in leukemia and a 1.6-fold increase in solid tumor among children under five years of age living in the inner 5 km circle around NPPs when compared to residence outside this area. These findings have been confirmed by two meta-analyses. Nevertheless, other UK, France, Spain and Finland studies did not find cancer incidence and/or death increase near NPPs. Conclusions Increased cancer risk near NPPs remains in fact an open question. The stronger evidence from the KiKK study suggests there may well be such increases at least in children regardless of the country in which nuclear reactors are located. In fact, few months ago the U.S. Nuclear Regulatory Commission has asked the National Academy of Sciences (NAS to perform a state-of-the-art study on cancer risk for populations surrounding NPPs.

    Full Text Available A molecular epidemiology survey was performed in order to establish and document the respiratory adenovirus pathogen profiles among children in Southern Palestine. Three hundred and thirty-eight hospitalized pediatric cases with adenovirus-associated respiratory tract infections were analyzed. Forty four cases out of the 338 were evaluated in more detail for the adenoviruses types present. All of the children resided in Southern Palestine, that is, in city, village and refugee camp environments within the districts of Hebron and Bethlehem. Human adenoviruses circulated throughout 2005-2010, with major outbreaks occurring in the spring months. A larger percent of the children diagnosed with adenoviral infections were male infants. DNA sequence analysis of the hexon genes from 44 samples revealed that several distinct adenovirus types circulated in the region; these were HAdV-C1, HAdV-C2, HAdV-B3 and HAdV-C5. However, not all of these types were detected within each year. This is the first study ever conducted in Palestine of the genetic epidemiology of respiratory adenovirus infections.

    Full Text Available Obesity is now recognised as a worldwide epidemic. The recent International Association for the Study of Obesity/International Obesity Taskforce (IASO/IOTF analysis estimates that approximately 1.0 billion adults are currently overweight and a further 475 million are obese. Obesity has huge psychosocial impact with obese children and adolescents facing discrimination and stigmatization in many areas of their lives leading to body dissatisfaction, low self-esteem and depression. Indeed, obesity is recognised as an important risk factor for the development of several chronic diseases such as hypertension, cancer, asthma and metabolic syndrome. Chronic low grade systemic inflammation is considered as a hallmark of obesity and may possibly explain the link between obesity and chronic disease, in particular the increased incidence, prevalence and severity of asthma in obese individuals. There is now strong evidence for infiltration of immune and inflammatory cells into adipose tissue that drives systemic inflammation and subsequent end organ damage. In addition to adipocytes, the key adipose tissue resident immune cells are macrophages and mast cells. Immunometabolism, as an emerging field of investigation, explores the pivotal role of these immune cells in translating immunological changes to metabolic effects in obesity. Abundance of free fatty acids, along with other inflammatory cytokines shift the balance of metabolic homeostasis to pro-inflammatory status by influencing the development of inflammatory cell lineage, which, further exhibits distinct functional phenotypes. There is emerging evidence for macrophage activation and functional polarization of an anti-inflammatory M2 phenotype towards a pro-inflammatory M1 phenotype of macrophages in obese adipose tissue. Similarly, studies in both obese humans and murine models reveal the pathognomic presence of an increased number of mast cells in visceral adipose tissue. These suggest a possible

    Cross-sectional analyses were conducted to evaluate the effects of exposure to highway traffic on pulmonary function in Fresno, California. Traffic and spirometry data were available for 214 children (enrollment ages six to 11 years). Multiple linear regression was used to evaluate the relations between pulmonary function and traffic parameters. Heavy-duty vehicle count was used as a surrogate measure for diesel-related exposures. Pulmonary function was non-significantly associated with longer distance-to-road and non-significantly associated with higher traffic intensity. Evaluation of effect modification by FEF(25-75)/FVC (a measure of intrinsic airway size) showed that all pulmonary function measures of flow were significantly inversely related to a traffic metric that incorporates traffic intensity and roadway proximity. The results indicate that residence proximity to highway traffic is associated with lower pulmonary function among children with asthma, and smaller airway size is an important modifier of the effect of traffic exposure on pulmonary function and a marker of increased susceptibility.

    Full Text Available OBJECTIVE: A case-control study of patients with pneumonia was conducted to investigate whether wheezing diseases could be a risk factor. METHODS: A random sample was taken from a general university hospital in S. Paulo City between March and August 1994 comprising 51 cases of pneumonia paired by age and sex to 51 non-respiratory controls and 51 healthy controls. Data collection was carried out by two senior paediatricians. Diagnoses of pneumonia and presence of wheezing disease were independently established by each paediatrician for both cases and controls. Pneumonia was radiologically confirmed and repeatability of information on wheezing diseases was measured. Logistic regression analysis was used to identify risk factors. RESULTS: Wheezing diseases, interpreted as proxies of asthma, were found to be an important risk factor for pneumonia with an odds ratio of 7.07 (95%CI= 2.34-21.36, when the effects of bedroom crowding (odds ratio = 1.49 per person, 95%CI= 0.95-2.32 and of low family income (odds ratio = 5.59 against high family income, 95%CI= 1.38-22.63 were controlled. The risk of pneumonia attributable to wheezing diseases is tentatively calculated at 51.42%. CONCLUSION: It is concluded that at practice level asthmatics should deserve proper surveillance for infection and that at public health level pneumonia incidence could be reduced if current World Health Organisation's guidelines were reviewed as to include comprehensive care for this illness.OBJETIVO: Investigar, através de um estudo caso-controle de pacientes com pneumonia, se as doenças chiadoras poderiam constituir-se em fator de risco.

    Poor indoor air quality has been linked to the exacerbation of asthma symptoms in children. Because people spend most of their time indoors, improving indoor air quality may provide some relief to asthma sufferers. A study was conducted to assess whether operating an air cleaning/ventilating unit (HEPAiRx {sup registered}) in a child's bedroom can improve his/her respiratory health. Thirty children diagnosed with asthma were randomly split into two groups. For the first six weeks, group A had the air cleaning/ventilating unit (HEPAiRx {sup registered}) running in the bedrooms of the participants and group B did not; for the second six weeks, both groups had the cleaners running in the bedrooms; and, for the final six weeks, group A turned the cleaners off and group B kept theirs running. Indoor air quality parameters, including temperature, relative humidity, particulate matter (PM 0.5-10 {mu}m), carbon monoxide, carbon dioxide and total volatile organic compound (TVOC) concentrations, were monitored in each bedroom using an AirAdvice indoor air quality multi-meter. As a measure of pulmonary inflammation, exhaled breath condensate (EBC) was collected every sixth day and analyzed for nitrate and pH. Peak expiratory flow (PEF) was also measured. PM and TVOC concentrations decreased with operation of the HEPAiRx an average of 72% and 59%, respectively. The EBC nitrate concentrations decreased significantly and the EBC pH and PEF values increased significantly with operation of the unit (p < 0.001 when comparing on/off sample means). These results indicate that air cleaning in combination with ventilation can effectively reduce symptoms for asthma sufferers. (author)

    Full Text Available The expired nitric oxide (NO concentration is known to be higher in asthmatic subjects than in normal subjects. To elucidate the role of NO in asthma, we examined the expired NO concentrations in relation to the type (atopic, mixed, non- atopic, and severity (mild, moderate, severe of asthmatics, as well as the influence of steroid treatment. Twenty-seven normal subjects, 48 asthmatics, 8 subjects with allergic rhinitis, and 13 subjects with pulmonary emphysema participated in the study. The expired NO concentration was significantly higher in asthmatics and patients with allergic rhinitis than in normal subjects (P<0.01. No significant difference was observed between the expired NO concentration in patients with pulmonary emphysema and that of normal subjects. The expired NO concentrations were significantly lower in non- atopic asthma than in atopic asthma. Nitric oxide levels were significantly lower in severe asthma than in mild asthma. High doses of steroid treatment are often used in severe asthma. The dose of inhaled beclomethasone and expired NO concentrations showed a negative correlation (r= −0.51587, P<0.004. Drip infusion of hydrocortisone tended to increase the exhaled NO concentration just after drip infusion, however, it decreased after 24 h. These results suggest that steroid treatment decreases the expired NO concentrations in asthmatics, although it cannot be concluded that NO increases the severity of asthma. The measurement of expired NO concentrations is an easy, non-invasive test, which may be a useful tool for monitoring the condition of asthmatics.

    , total IgE, specific IgE, peak expiratory flow rate (PEF), etc. during a standardized SIT against house dust mite in allergic asthmatic children. Method Children (5-13 years old) with mild to moderate allergic asthma seen from February 2005 to June 2008 were enrolled into this study. A non- randomized retrospective study was performed. All children were diagnosed sensitive to dust mites, the treatment group accepted standardized dust mite allergen specific immunotherapy. Each fourth injections were defined as observation points, the study took 3.4 years. The investigators recorded the treatment, the cumulative allergen extract, changes of daffy doses of inhaled corticosteroid, peak expiratory flow (PEF), total IgE (TIgE), specific IgE (SIgE). The control group only received inhaled corticosteroids. The daily doses of inhaled corticosteroid and the number of asthma attacks,and the control rate were compared between the 2 groups. Result Totally 85 children were treated with SIT [(7.6 ± 1.4) years], 45 males and 40 females; 50 children received only drug treatment [(7.7 ± 1.5)years], 28 males and 22 females. The cumulative dose of allergen was up to (69.7 ± 4.8) μg after the 20 times injection, the dose of inhaled corticosteroids was significantly less than that in the control group ( t =2. 359, P < 0.05). PEF was significantly higher than that of pre-treatment level ( F = 7.874, P < 0.05 ).TIgE and SIgE had no significant change (t = 0.313, P > 0.05, tDerp = 0.517, tDerf = 0.717,P > 0.05 ). After the treatment, the control rate of the SIT group was 85.5%, that of the control group was 62.0% (X2 =10.150, P <0.01).

    Full Text Available Undernutrition among children is a major public health concern worldwide, more prevalent in Asia and Africa. It manifests itself in various forms such as wasting or stunting or underweight and retards physical and mental development, increases susceptibility to infection, and reduces educational attainment and productivity. The present study was undertaken to assess the level of wasting, stunting, and underweight and determine its associates among slum children of 3–9 years of age, residing in Bhubaneswar city, India. After obtaining informed consent, a total of 249 children from 249 households were studied and their parents/guardians were interviewed to collect all relevant information. 23.3%, 57.4%, and 45.4% of children were found to have wasting, stunting, and underweight, respectively. Variables like birth order of child, period of initiation of breastfeeding and mother’s education were found to be strong predictors of wasting, whereas toilet facility in household and practice of drinking water storage were significantly associated with stunting among slum children as revealed in multiple regression analysis. Thus, a multipronged approach is needed such as giving priority to improve education for slum community especially for women, creating awareness regarding benefits of early initiation of breastfeeding, small family size, and proper storage of drinking water, and providing toilet facility in slum households which could improve the nutritional status of slum children.

  20. Directional secretory response of double stranded RNA-induced thymic stromal lymphopoetin (TSLP and CCL11/eotaxin-1 in human asthmatic airways.

    Gustavo Nino

    Full Text Available BACKGROUND: Thymic stromal lymphoproetin (TSLP is a cytokine secreted by the airway epithelium in response to respiratory viruses and it is known to promote allergic Th2 responses in asthma. This study investigated whether virally-induced secretion of TSLP is directional in nature (apical vs. basolateral and/or if there are TSLP-mediated effects occurring at both sides of the bronchial epithelial barrier in the asthmatic state. METHODS: Primary human bronchial epithelial cells (HBEC from control (n = 3 and asthmatic (n = 3 donors were differentiated into polarized respiratory tract epithelium under air-liquid interface (ALI conditions and treated apically with dsRNA (viral surrogate or TSLP. Sub-epithelial effects of TSLP were examined in human airway smooth muscle cells (HASMC from normal (n = 3 and asthmatic (n = 3 donors. Clinical experiments examined nasal airway secretions obtained from asthmatic children during naturally occurring rhinovirus-induced exacerbations (n = 20 vs. non-asthmatic uninfected controls (n = 20. Protein levels of TSLP, CCL11/eotaxin-1, CCL17/TARC, CCL22/MDC, TNF-α and CXCL8 were determined with a multiplex magnetic bead assay. RESULTS: Our data demonstrate that: 1 Asthmatic HBEC exhibit an exaggerated apical, but not basal, secretion of TSLP after dsRNA exposure; 2 TSLP exposure induces unidirectional (apical secretion of CCL11/eotaxin-1 in asthmatic HBEC and enhanced CCL11/eotaxin-1 secretion in asthmatic HASMC; 3 Rhinovirus-induced asthma exacerbations in children are associated with in vivo airway secretion of TSLP and CCL11/eotaxin-1. CONCLUSIONS: There are virally-induced TSLP-driven secretory immune responses at both sides of the bronchial epithelial barrier characterized by enhanced CCL11/eotaxin-1 secretion in asthmatic airways. These results suggest a new model of TSLP-mediated eosinophilic responses in the asthmatic airway during viral-induced exacerbations.

    To determine if there are differences in the nitric oxide metabolites (nitrites) in sputum of patients with persistent asthma and healthy schoolchildren, we performed a case-control study in a tertiary care hospital in Arequipa, Perú. Nitrites in induced sputum samples were measured using the Griess assay in 30 persistent asthmatics (mean age of 10.1 yr) and 30 controls (mean age of 11.9 yr). The mean +/- s.d. of nitrites among asthmatics was significantly higher than the controls (16.30 +/- 8.6 vs. 10.25 +/- 4.68 nmol/ml, respectively, p = 0.001). Moreover, the nitrite level in the sputum in children with severe persistent asthma was higher than in the level found in the moderate and mild asthmatics (32.83 +/- 9.48 vs. 18.10 +/- 1.96 vs. 11.84 +/- 4.73 nmol/ml, respectively, p < 0.01 for linear trend). This study showed for the first time in children that asthmatics have significantly higher levels of nitrites in induced sputum than healthy controls and that the level of nitrite correlates with the severity of the asthma. Nitrite levels in sputum, a simple and cheap, non-invasive method, may be a good alternative to measure the severity of inflammation in asthmatic children.

The Lactobacillus count in study group was (43553.19 ± 58776.96 higher than the control group (8843.84 ± 7982.72 P < 0.01. Subjects using inhaled corticosteroids were more prone to develop dental caries than the control group with odds ratio = 6.26 and 95% confidence interval. Conclusions: The dental caries prevalence increases with the usage of β2agonist and corticosteroid inhalers for the treatment of asthma. Thus in asthmatic children, increase in caries prevalence might be due to the drug treatment and not due to the disease by itself. It can be concluded that asthmatic children have a higher prevalence of dental caries than healthy children. Hence, special oral health care is needed for asthmatic children.

    prestar adequada assistência a crianças e adolescentes asmáticos, especialmente para os menores de dois anos de idade.OBJECTIVE: To assess the prevalence rate and risk factors for hospital admissions among asthma children and to evaluate care delivered to these patients. METHODS: Three-hundred and twenty-five asthmatic children attending a public outpatient reference clinic were studied. Of them, 202 were hospitalized. Care was evaluated using a questionnaire covering general aspects of hospital stay and biological, demographics, socioeconomic and asthma-related factors. Univariate and multivariate analyses were performed to measure the association between hospital admissions and selected independent variables. RESULTS: Of the total, 62.2% had already been hospitalized due to asthma, 64.9% developed asthma episodes, and 60.9% were hospitalized in their first year of life. Most (76.0% had moderate to severe asthma. Despite that, 94.2% were not on anti-inflammatory drugs and were treated only during isolated acute episodes. None of these were regularly seen in primary health care centers for a periodic control of their steroid inhalants. Most parents (97.8% referred not to know how to take care of asthma children. Symptoms onset is normally seen before the age of 12 months (OR=3.20; 95%CI 1.55-6,61 or between 12 and 24 months (OR=3.89; 95%CI 1.62-9.36. Mothers have attended school for less than 7 years (OR=3.06; 95%CI 1.62-5.76. Disease severity (OR=2.32; 95%CI 1.24-3.88, 2 or more monthly visits to emergency wards (OR=2.19; 95%CI 1.24-3.88, and referred recurrent pneumonia (OR=2.00; 95%IC 1.06-3.80 were the main risk factors for hospital admissions. CONCLUSIONS: Organizing health care services is crucial to reduce hospital admissions and provide adequate care for asthma children and adolescents, especially those less than 2 years old.

    Increases in glomerular size occur with normal body growth and in many pathologic conditions. In this study, we determined associations between glomerular size and numbers of glomerular resident cells, with a particular focus on podocytes. Kidneys from 16 male Caucasian-Americans without overt renal disease, including 4 children (≤3 years old) to define baseline values of early life and 12 adults (≥18 years old), were collected at autopsy in Jackson, Mississippi. We used a combination of immunohistochemistry, confocal microscopy, and design-based stereology to estimate individual glomerular volume (IGV) and numbers of podocytes, nonepithelial cells (NECs; tuft cells other than podocytes), and parietal epithelial cells (PECs). Podocyte density was calculated. Data are reported as medians and interquartile ranges (IQRs). Glomeruli from children were small and contained 452 podocytes (IQR=335-502), 389 NECs (IQR=265-498), and 146 PECs (IQR=111-206). Adult glomeruli contained significantly more cells than glomeruli from children, including 558 podocytes (IQR=431-746; Pnumber of podocytes in large glomeruli does not match the increase in glomerular size observed in adults, resulting in relative podocyte depletion. This may render hypertrophic glomeruli susceptible to pathology.

    Full Text Available During asthma development, differentiation of epithelial cells and fibroblasts towards the contractile phenotype is associated with bronchial wall remodeling and airway constriction. Pathological fibroblast-to-myofibroblast transition (FMT can be triggered by local inflammation of bronchial walls. Recently, we have demonstrated that human bronchial fibroblasts (HBFs derived from asthmatic patients display some inherent features which facilitate their FMT in vitro. In spite of intensive research efforts, these properties remain unknown. Importantly, the role of undifferentiated HBFs in the asthmatic process was systematically omitted. Specifically, biomechanical properties of undifferentiated HBFs have not been considered in either FMT or airway remodeling in vivo. Here, we combine atomic force spectroscopy with fluorescence microscopy to compare mechanical properties and actin cytoskeleton architecture of HBFs derived from asthmatic patients and non-asthmatic donors. Our results demonstrate that asthmatic HBFs form thick and aligned 'ventral' stress fibers accompanied by enlarged focal adhesions. The differences in cytoskeleton architecture between asthmatic and non-asthmatic cells correlate with higher elastic modulus of asthmatic HBFs and their increased predilection to TGF-β-induced FMT. Due to the obvious links between cytoskeleton architecture and mechanical equilibrium, our observations indicate that HBFs derived from asthmatic bronchi can develop considerably higher static tension than non-asthmatic HBFs. This previously unexplored property of asthmatic HBFs may be potentially important for their myofibroblastic differentiation and bronchial wall remodeling during asthma development.

    The Sociedad Argentina de Pediatría, SAP (Argentine Society of Pediatrics) offers courses and scientific activities for pediatricians and residents. We evaluated the participation of Pedro de Elizalde Hospital residents in the scientific and training activities of SAP and assessed the trend of participation throughout the residency; 107 residents were surveyed; 48% were members, and the participation increased significantly throughout the residence (p <0.01). None of the surveyed residents were part of any association; 84% did not know the "Pediatricians in Training Group"; 49% participated in continued training programs, with a growing tendency to participation through-out the residency (p <0.01); 80% considered that the SAP is a friendly entity. We concluded that participation of residents in the SAP is scarce during the first two years of training, and that it shows a growth in the senior residents' group. Encouraging the interest of first and second year residents in the activities is necessary.

    Our objective was to examine the association between parental immigration status and child health and health care utilization. Using data from a national sample of immigrant adults who had recently become legal permanent residents (LPR), children (n = 2,170) were categorized according to their parents' immigration status prior to LPR: legalized, mixed-status, refugee, temporary resident, or undocumented. Logistic regression with generalized estimating equations was used to compare child health and health care utilization by parental immigration status over the prior 12 months. Nearly all children in the sample were reported to be in good to excellent health. Children whose parents had been undocumented were least likely to have had an illness that was reported to have required medical attention (5.4 %). Children whose parents had been either undocumented or temporary residents were most likely to have a delayed preventive annual exam (18.2 and 18.7 %, respectively). Delayed dental care was most common among children whose parents had come to the US as refugees (29.1 %). Differences in the preventive annual exam remained significant after adjusting for socioeconomic characteristics. Parental immigration status before LPR was not associated with large differences in reported child health status. Parental immigration status before LPR was associated with the use of preventive annual exams and dental services. However, no group of children was consistently disadvantaged with respect to all measures.

    Full Text Available Background: Asthma constitutes the first disease among chronic diseases in children. The morbid-mortality promoted to continue being elevated in spite of the new therapies. For this reason it is a disease with high priority for investigation in pediatric ages. Method: A control and case group study was carried out. The samples was composed by 72 asthmatic children from three General Comprehensive doctor offices from Palmira health area located in Cienfuegos Province, Cuba; and a control group of 72 children apparently healthy from the same population. A questionnaire with the different risk variables was elaborated. Odds ratio technique was used to estimate the risk. Results: low weight at birth, family history of asthma, brochiolitis antecedent and the excessive usage of antibiotics in children under 1 year old were the main risks found. Conclusions: It is conclusive that the exposure to home allergen plus a genetic favorable factor, the prematurity, and brochiolitis constituted the most outstanding elements to suffer from asthma in the population studied.

    A small spill of approximately 3 mL of mercury from a broken barometer in a residential setting resulted in blood values of 32 μg/L in a boy of 9 months and 26 μg/L in a girl of 2.5 years in samples collected within 6h after the start of the incident. A nanny who attempted to remove the spill had a blood mercury value of 20 μg/L at the same time point. These elevated blood values were attributed to inhalation rather than dermal uptake or ingestion. Exposure was aggravated by the use of a vacuum cleaner in an early attempt to remove the spill and incomplete decontamination of involved persons, leading to a continuation of exposure. Over a period of three months general cleaning was followed by targeted cleaning of hot spots until the indoor air mercury levels reached a median value of 0.090 μg/m(3) with a range of 0.032-0.140 μg/m(3). Meanwhile the family was staying in a shelter home. Human biological monitoring (HBM) was motivated by the complex exposure situation and the involvement of young children. Initially high blood values triggered alertness for clinical signs of intoxication, that (as it turned out) were not observed in any of the exposed individuals. Despite continued exposure from hair and clothes, within six weeks after the incident, blood levels returned to a background level normally seen in children. HBM contributed to reassurance of the parents of the young children that quick elimination of the mercury did not require medical treatment.

    Full Text Available Asthma is one of the most prevalent chronic inflammatory lung diseases among children and adults. A lot of work had been done in various field (including both modern and Ayurvedic on anti-asthmatic drugs to evaluate their action on lungs. The parameters chosen for assessing the properties of drug is mainly based on clinical improvement and improvement in pulmonary function test. These all method employed so far are indirect method for assessment of action of drug on lungs as change in pulmonary function may appear without any relevant change in lungs mechanics. In present study we assess the anti-asthmatic effect of drug directly on respiratory parameter by using MATLAB lung mechanics modeling. Administration of drug is equally distributed throughout lungs and produces significant increase in lung volume which is attributed to the decrease in airways resistance and increase in lung compliance.

The probability of misclassification using all eleven parameters was 19.64% in the analysis of healthy adults and mild asthmatics, and 4.29% in the analysis of healthy adults and moderate asthmatics. There was a little difference in the parameters selected at every step. The discriminant analysis proved that the flow-volume patterns were different according to the severity of bronchial asthma. Thus flow-volume recognition was considered to be important in analyzing the severity of bronchial asthma.

    Full Text Available : This study was done to observe the serum/plasma oxidant-antioxidant status among asthmatic patients. Plasma MDA (Malon-di-aldehyde, an oxidant and Serum SOD (superoxide dismutase, an antioxidant, were assayed among asthmatic patients and their mean values were compared with healthy volunteer controls. Values were also observed in different age groups. The difference in mean pMDA level was found statistically significantly among cases and control, higher among asthmatic patients. Likewise, s-SOD level was significantly reduced among asthmatic patients. Clearly, there was an imbalance between oxidants and antioxidants levels among asthmatic patients and this consideration may be helpful in proper planning of basket of anti-asthma interventions. Future studies are recommended.

    Chlamydia pneumoniae respiratory tract infections were studied in 512 male military conscripts (123 asthmatic and 389 non-asthmatic) taking part in 180-day service between July 2004 and July 2005 in Kajaani, Finland. Respiratory tract infections requiring a medical consultation were analysed prospectively. At baseline, at end of service, and during each episode of respiratory infection, blood samples were obtained for measurement of C. pneumoniae antibodies. Data concerning the clinical features of each infection episode were collected. Serological evidence of acute C. pneumoniae infection was found in 34 of the 512 conscripts with antibody data available, including 9.8% of the asthmatic subjects and 5.7% of the non-asthmatic subjects (p 0.111). A serological diagnosis could be made for 25 clinical episodes in 24 conscripts. The spectrum of respiratory tract infections included 13 episodes of mild upper respiratory tract infection and seven episodes of sinusitis, with five episodes involving asthma exacerbation. Two of three pneumonias were primary infections. Primary infections were diagnosed in five subjects, and re-infection/reactivation in 19 subjects, with the latter comprising 12 non-asthmatic subjects and seven asthmatic subjects (p 0.180). Prolonged infections were present in six asthmatic subjects and one non-asthmatic subject (p 0.001). A wide variety of respiratory tract infections, ranging from common cold to pneumonia, were associated with serologically confirmed C. pneumoniae infections. Infections were often mild, with common cold and sinusitis being the most common manifestations. Acute, rapidly resolved C. pneumoniae infections were equally common among asthmatic subjects and non-asthmatic subjects, whereas prolonged infections were more common among subjects with asthma.

    Objective To study the variety of airborne allergenic insects and its sensibility in asthmatic patients. Methods 300 asthmatic patients and 100 normal controls underwent skin prick test (SPT) with 13 kinds of superior airborne insect vaccine, and sera sIgE of those whose SPT results were positive were tested by BSA-ELISA. Results The total positive rate of SPT with 13 kinds of insect vaccine in asthmatic patients was 58%, and it was significantly higher than that of normal control (P<0.01). The results of SPT with Stayridae, Heliothis armigera, Psilgramma menephorn and other 7 kinds of insects were more than 30% in asthmatic patients which meant these 10 kinds of insects were main allergenic insects to asthmatic patients. The positive rate of sIgE in asthmatic patients was more than 85%, while the normal control was only 6.0%. There was significant difference between two groups (P<0.01). Conclusion Stayridae, Heliothis armigera, Psilgramma menephorn and other 7 kinds of insects were main allergenic insects to asthmatic patients and perhaps they were the main allergens to the onset of asthma at the end summer or the early autumn.

    Background Airway symptoms in asthma are related to decrease of epinephrine secretion, which may be ascribed to elevated nerve growth factor (NGF) in the organism.The aim of this study was to monitor the neuroendocrine alteration in the adrenal medulla of asthmatic rats.Methods Sixteen rats were randomly divided into two groups (n=8), control group and asthma group, and the asthmatic rats were sensitized and challenged with ovalbumin (OVA).The levels of NGF, epinephrine and norepinephrine in serum were detected by enzyme linked immunosorbent assay (ELISA), the NGF expression in adrenal medulla was detected by immunohistochemistry, and the changes in the ultrastructure of the adrenal medulla was observed by electron microscopy.Results The NGF expression was increased in asthmatic rats compared with control rats.Compared with control rats,the results indicated that the epinephrine level was decreased in asthmatic rats, but no significant difference was found in norepinephrine levels.We found more ganglion cells in the adrenal medulla of asthmatic rats than in control rats, with NGF immunostaining mainly located in these ganglion cells.Electron microscopic images showed the density of chromaffin granula decreased and there was shrunken nucleolemma in the adrenal medullary cells of asthmatic rats.Conclusion The innervation of the adrenal medulla is changed in asthmatic rats, and it may contribute to the epinephrine decrease in asthma.

La frecuencia de positividad de la prueba de broncoprovocación fue mayor en el Grupo MG que en el IL (93 versus 65%. El tiempo necesario para la reducción de 20% del VEF1 para el grupo de atópicos fue menor en el MG cuando comparado al IL, 90 (30 a 330 versus 210 (30 a 690 segundos, con pOBJECTIVE: To verify if the bronchoprovocation test with 4.5% hypertonic saline solution allows to detect the gradient of response in asthmatic children and adolescents, according to asthma severity. METHODS: 75 asthmatic patients aged six to 18 years-old were evaluated in this cross-sectional study. They were classified according to asthma severity in: intermittent or mild persistent (IM and moderate or severe persistent (MS. They were also classified according to sensitization to inhaled allergens in atopics: positive skin prick test to Dermatophagoides pteronyssinus, D. farinae and Blomia tropicalis; or non- atopic with negative skin prick tests. All patients underwent a bronchoprovocation test with 4.5% hypertonic saline solution. The result of the bronchoprovocation test was considerd positive if at least a reduction of 20% in the forced expiratory volume in one second (FEV1 was noted. RESULTS: 60 individuals were atopic. The bronchoprovocation test was positive more frequently in the MS group than in the IM one (93 versus 65%. Less time was needed for a 20% fall of FEV1 in the MG compared to the IL group [90 (30 - 330 versus 210 (30 - 690 seconds; p<0.05]. The percentage of FEV1 fall was higher in the MG group than in the IL one [26,4% (14 - 63 versus 20% (0 - 60; p<0.05]. CONCLUSIONS: The 4.5% hypertonic saline solution bronchoprovocation test is safe and easy to perform. It detects a gradient of response in asthmatic children and adolescents regarding asthma severity. Higher frequency of positive tests, shorter

    The use of spacer devices is recommended in asthmatic children for inhaled therapeutics. Therefore, in vitro studies prove the dependent-device delivery of the drug. The aim of this study was to compare, in vivo, the effect of 200 micrograms of albuterol, delivered via one of the five spacer devices currently marketed in France (Aerochamber, Aeroscopic, Babyhaler with a face mask, Nebuhaler or Volumatic) and assessed by the induced peak expiratory flow (PEF) change. One hundred asthmatic children were recruited and randomized in 5 groups. The mean age was 8.9 +/- 3.3 years. Each group was comparable regardless of gender, height, weight, characteristics of asthma and baseline PEF. The maximal change in PEF was obtained with Babyhaler (14.9 +/- 12.8%; p = 0.009). The increase in PEF elicited with Aeroscopic was 9.7 +/- 10.2%. The others spacer devices did not offer a change greater than the variation of PEF in the studied population. Further studies, concerned with a measurement of drug deposition or with an assessment of its use in obstructive episodes of asthma, are required, but Babyhaler with a face mask, usually reserved to infants, deserves to be advised to older children for salbutamol intake.

    Objective: To assess the haematological and lipid profile assays in asthmatics. Methods: Eighty asthmatic subjects were prospectively studied in a major referral centre serving the Niger Delta region of Nigeria for 12 months (2006-2007). Clinico-haematological and serum lipid total cholesterol (TC), triglyceride (TG), and lipoproteins concentration were analyzed after adjusting for age, cigarette smoking, alcohol ingestion, hypertension and diabetes mellitus. Results: Eighty patients (34 males and 46 females) were seen with female predominating in the various age groups (M∶ F ratio, 0.7∶ 1). Total cholesterol and low density lipoproteins-cholesterol for the asthmatics was significantly higher than the controls (P2.3mmol/L) and a significant hypercholesterolemia (HC, >5.2mmol/L) according to the Adult Treatment Panel III definition in asthmatics thereby putting them at increased risk for the development of cardiovascular disease as well as other disorders related to excess lipids. There was a significant thrombocytopenia (P<0.000 1) which may accompany allergen exposure and this persists for 24 h; that asthmatics of African descent showed a significantly increased total leucocyte count (P=0.001) similar to other studies in the Western countries. Conclusion: Hyperlipidaemia is a prevalent medical problem among asthmatics; hence screening for fasting serum lipid levels to identify those who need early intervention is recommended.

  15. Physiological Changes at Altitude in Nonasthmatic and Asthmatic Subjects

    2004-01-01

    Full Text Available Exercised-induced asthma is not due to exercise itself per se, but rather is due to cooling and/or drying of the airway because of the increased ventilation that accompanies exercise. Travel to high altitudes is accompanied by increased ventilation of cool, often dry, air, irrespective of the level of exertion, and by itself, this could represent an 'exercise' challenge for asthmatic subjects. Exercise-induced bronchoconstriction was measured at sea level and at various altitudes during a two-week trek through the Himalayas in a group of nonasthmatic and asthmatic subjects. The results of this study showed that in mild asthmatics, there was a significant reduction in peak expiratory flow at very high altitudes. Contrary to the authors' hypothesis, there was not a significant additional decrease in peak expiratory flow after exercise in the asthmatic subjects at high altitude. However, there was a significant fall in arterial oxygen saturation postexercise in the asthmatic subjects, a change that was not seen in the nonasthmatic subjects. These data suggest that asthmatic subjects develop bronchoconstriction when they go to very high altitudes, possibly via the same mechanism that causes exercise-induced asthma.

    Full Text Available Abstract Background The non-invasive assessment of airway inflammation is potentially advantageous in asthma management. Exhaled carbon monoxide (eCO measurement is cheap and has been proposed to reflect airway inflammation and oxidative stress but current data are conflicting. The purpose of this meta-analysis is to determine whether eCO is elevated in asthmatics, is regulated by steroid treatment and reflects disease severity and control. Methods A systematic search for English language articles published between 1997 and 2009 was performed using Medline, Embase and Cochrane databases. Observational studies comparing eCO in non-smoking asthmatics and healthy subjects or asthmatics before and after steroid treatment were included. Data were independently extracted by two investigators and analyzed to generate weighted mean differences using either a fixed or random effects meta-analysis depending upon the degree of heterogeneity. Results 18 studies were included in the meta-analysis. The eCO level was significantly higher in asthmatics as compared to healthy subjects and in intermittent asthma as compared to persistent asthma. However, eCO could not distinguish between steroid-treated asthmatics and steroid-free patients nor separate controlled and partly-controlled asthma from uncontrolled asthma in cross-sectional studies. In contrast, eCO was significantly reduced following a course of corticosteroid treatment. Conclusions eCO is elevated in asthmatics but levels only partially reflect disease severity and control. eCO might be a potentially useful non-invasive biomarker of airway inflammation and oxidative stress in nonsmoking asthmatics.

    were most often affected. The overall asthma hospitalization rate was 1.3% (336/25,802, rising to 10.7% (336/3140 among the asthmatic children treated in the emergency room. In the rainy season, the percentage of outpatients seeking treatment for asthma was higher than in the dry season: 39.1% (1228/3140 versus 60.9% (1912/3140. However, during the dry season, a greater proportion of such patients were hospitalized: 52.3% (176/336 versus 47.7% (160/336. These differences were statistically significant (p < 0.05. CONCLUSIONS: The dry season, which was correlated with higher asthma hospitalization rates, seems to be related to more severe cases of asthma in children under five years of age.

    The article assessed knowledge of the nutritional and health needs of children among rural dwellers in Nigeria. Focus group discussions were conducted with all male and female groups in four purposively chosen rural communities in Nsukka Senatorial zone of Enugu State. These generated data on participants' knowledge on the nutritional and health needs of the children as well as their socio-demographic characteristics. All the participants were married with mean age of 41 and 36 years for males and females, respectively. The participants had six and four children on the average for male and female participants, respectively. Findings show that participants demonstrate knowledge of basic dietary needs of children; however, actual practice is lacking. Men believe women have the sole responsibility for children's nutrition. Exclusive breastfeeding is not adhered to by participants. Some reservation still exists about immunization. Sustained health education on exclusive breastfeeding and child immunization targeting both sexes is still needed.

    Full Text Available Asthma is characterised by reversible airway obstruction. In most patients, control of disease activity is easily achieved. However, in a small minority, asthma may be fatal. Between the two extremes lie patients with severe asthmatic attacks, refractory to standard treatment. These patients are at an increased risk of recurrent severe attacks, with respiratory failure, and mechanical ventilation. Invasive mechanical ventilation of the asthmatic patient is associated with a higher risk of complications and, therefore, is a measure of last resort. Noninvasive positive pressure ventilation (NPPV is another treatment modality that may be beneficial in patients with severe asthmatic attack who are at an increased risk of developing respiratory failure. These patients have the potential to benefit from early respiratory support in the form of NPPV. However, reports of NPPV in asthmatic patients are scarce, and its usage in asthmatic attacks is, therefore, still controversial. Only a few reports of NPPV in asthma have been published over the last decade. These studies mostly involve small numbers of patients and those who have problematic methodology. In this article we review the available evidence for NPPV in asthma and try to formulate our recommendations for NPPV application in asthma based on the available evidence and reports.

    It has long been known that airway smooth muscle (ASM) contraction contributes significantly to the reversible airflow obstruction that defines asthma. It has also been postulated that phenotypic changes in ASM contribute to the airway hyper-responsiveness (AHR) that is a characteristic feature of asthma. Although there is agreement that the mass of ASM surrounding the airways is significantly increased in asthmatic compared with non-asthmatic airways, it is still uncertain whether there are quantitative or qualitative changes in the level of expression of the genes and proteins involved in the canonical contractile pathway in ASM that could account for AHR. This review will summarize past attempts at quantifying gene expression changes in the ASM of asthmatic lungs as well as non-asthmatic ASM cells stimulated with various inflammatory cytokines. The lack of consistent findings in asthmatic samples coupled with the relative concordance of results from stimulated ASM cells suggests that changes to the contractility of ASM tissues in asthma may be dependent on the presence of an inflammatory environment surrounding the ASM layer. Removal of the ASM from this environment could explain why hypercontractility is rarely seen ex vivo.

    Pulmonary and thermoregulatory reactions to body cooling were studied in eight asthmatic and five normal subjects. The cooling was achieved by a cold shower at water temperature (T) of 15 degrees C for 1 min, followed by exposing the wet body to a high wind generated by a fan for another minute. The skin T, oral T and pulmonary functions were measured before and after cooling. After the cooling, skin T fell a mean of 7 degrees in all subjects and the oral T fell 0.5 degrees in the normals and 0.7 degrees in the asthmatics. In asthmatics, the post-cooling forced expiratory volume in 1 s (FEV1) and maximal mid-expiratory flow (MMEF) fell significantly (P less than .05) to a mean of 79% and 72%of baseline, respectively, and thoracic gas volume (TGV) and airway resistance (Raw) increased significantly to 133% and 198% of baseline, respectively. In normal subjects a small but significant increase in Raw was found. No obstruction developed in the asthmatics after a warm shower at 37 degrees or after breathing the cold shower mist. It is suggested that it is body cooling which leads first to vasoconstriction and then cooling of respiratory mucosa that initiates bronchoconstriction in asthmatics.

    Full Text Available Oxidative stress is involved in the pathogenesis of asthma. Paraoxonase 1 (PON1 and arylesterase are esterase enzymes displaying antioxidant characteristics. PON1 activity varies widely among individuals and ethnic groups, partly related to polymorphisms. The aim of this study was to determine the activities of PON1 and arylesterase including the phenotype distribution of PON1 in asthmatic patients and healthy subjects. Forty-nine asthmatic patients and 41 healthy people were included in this study. Serum PON1 and arylesterase activities were determined by spectrophotometric assays, as well as the lipid profiles. The PON1 ratio (salt stimulated paraoxonase/arylesterase was trimodally distributed and this ratio was used to determine the individual phenotypes of all subjects. The PON1 activity in the asthmatic patients was significantly lower (p=0.024 when compared to the healthy control group, however no significant difference in the activity of arylesterase was observed between the two groups. The prevalence of the PON1 phenotypes in the asthmatic population were 26.5%, 16.3% and 57.2 % for QQ, QR and RR, respectively. PON1 activity was significantly lower in asthmatic patients; in addition, the results of this investigation indicated that PON1 RR phenotype may be an important risk factor in asthma disease.

    Conclusions: Children living at high altitude in China have significantly higher mPAP, dilated right heart and slower regression of right ventricular hypertrophy in the first 14 years of life. Systolic and diastolic functions of both ventricles were reduced with a paradoxically higher CI. There was no significant difference in these features between the Hans and the Tibetans. These values provide references for the care of healthy children and the sick ones with cardiopulmonary diseases at high altitude.

    Full Text Available BACKGROUND: Haemophilus influenzae type b (Hib vaccine and pneumococcal conjugate vaccine (PCV are relatively expensive, newly introduced vaccines in China. This study evaluates the impact of residency and urbanicity on Hib vaccine and PCV coverage for children aged 2 to 7 years living in Shanghai, China, in August 2012. METHODS: In this exploratory cohort study, a sample of children aged 2 to 7 years, all of whom were eligible to have received the complete series of Hib vaccine and PCV, was obtained from the Shanghai Immunization Program Information System. Three measures of vaccination coverage for Hib vaccine and PCV were examined: dose 1 coverage, series completion, and timeliness of dose 1 vaccination. Multivariable binomial regression was used to estimate the difference in vaccination coverage between locals and the floating population. RESULTS: Dose 1 coverage was 50.9% for Hib vaccine and 11.4% for PCV for the 28,141 abstracted pediatric records. For both vaccines, dose 1 coverage was higher in locals than in the floating population. The disparity in coverage between locals and the floating population was greater in suburban areas than urban areas. Of all children who received dose 1, 79.7% completed the Hib vaccine series, and 91.3% completed the PCV series. Timely dose 1 coverage was 8.2% for Hib vaccine and 0.5% for PCV. CONCLUSION: Low vaccination coverage and extremely low levels of timely dose 1 vaccination indicate that current vaccination efforts are inadequate to reduce the burden of Hib and pneumococcal disease among Chinese children, especially infants. Government funding of the Hib vaccine and PCV through the Expanded Program on Immunization would increase uptake and could also ensure that improvement in the timeliness of administration and series completion is targeted for all demographic groups.

    Science.gov (United States)

    BACKGROUND: Asthma is a known risk factor for acute ozone-associated respiratory disease. Ozone causes an immediate decrease in lung function and increased airway inflammation. The role of atopy and asthma in modulation of ozone-induced inflammation has not been determined. OBJECTIVE: We sought to determine whether atopic status modulates ozone response phenotypes in human subjects. METHODS: Fifty volunteers (25 healthy volunteers, 14 atopic nonasthmatic subjects, and 11 atopic asthmatic subjects not requiring maintenance therapy) underwent a 0.4-ppm ozone exposure protocol. Ozone response was determined based on changes in lung function and induced sputum composition, including airway inflammatory cell concentration, cell-surface markers, and cytokine and hyaluronic acid concentrations. RESULTS: All cohorts experienced similar decreases in lung function after ozone. Atopic and atopic asthmatic subjects had increased sputum neutrophil numbers and IL-8 levels after ozone exposure; values did not significantly change in healthy volunteers. After ozone exposure, atopic asthmatic subjects had significantly increased sputum IL-6 and IL-1beta levels and airway macrophage Toll-like receptor 4, Fc(epsilon)RI, and CD23 expression; values in healthy volunteers and atopic nonasthmatic subjects showed no significant change. Atopic asthmatic subjects had significantly decreased IL-10 levels at baseline compared with healthy volunteers; IL-10 levels did not significa

    Full Text Available Although asthma has been commonly associated with sensitivity to cockroaches, a clear causal relationship between asthma, allergy to cockroaches and exposure levels has not been extensively investigated. The objective of the present study was to determine whether asthma occurs more frequently in children living in homes with high cockroach infestation. The intensity of household infestation was assessed by the number of dead insects after professional pesticide application. Children living in these houses in the metropolitan area of Recife, PE, were diagnosed as having asthma by means of a questionnaire based on the ISAAC study. All children had physician-diagnosed asthma and at least one acute exacerbation in the past year. Children of both sexes aged 4 to 12 years who had been living in the households for more than 2 years participated in this transverse study and had a good socioeconomic status. In the 172 houses studied, 79 children were considered to have been exposed to cockroaches and 93 not to have been exposed. Children living in residences with more than 5 dead cockroaches after pesticide application were considered to be at high infestation exposure. Asthma was diagnosed by the questionnaire in 31.6% (25/79 of the exposed group and in 11.8% (11/93 of the non-exposed group (P = 0.001, with a prevalence ratio of 3.45 (95%CI, 1.48-8.20. The present results indicate that exposure to cockroaches was significantly associated with asthma among the children studied and can be considered a risk factor for the disease. Blattella germanica and Periplaneta americana were the species found in 96% of the infested houses.

    Present understanding of the pathophysiological mechanisms of asthma has been severely limited by the lack of an imaging modality capable of assessing airway conditions of asthma patients in vivo. Of particular interest is the role that airway smooth muscle (ASM) plays in the development of asthma and asthma related symptoms. With standard Optical Coherence Tomography (OCT), imaging ASM is often not possible due to poor structural contrast between the muscle and surrounding tissues. A potential solution to this problem is to utilize additional optical contrast factors intrinsic to the tissue, such as birefringence. Due to its highly ordered structure, ASM is strongly birefringent. Previously, we demonstrated that Polarization Sensitive OCT(PS-OCT) has the potential to be used to visualize ASM as well as easily segment it from the surrounding (weakly) birefringent tissue by exploiting a property which allows it to discriminate the orientation of birefringent fibers. We have already validated our technology with a substantial set of histological comparisons made against data obtained ex vivo. In this work we present a comprehensive comparison of ASM distributions in asthmatic and non-asthmatic human volunteers. By isolating the ASM we parameterize its distribution in terms of both thickness and band width, calculated volumetrically over centimeters of airway. Using this data we perform analyses of the asthmatic and non-asthmatic airways using a broad number and variety and subjects.

    Full Text Available Abstract Background In 1996, Mexico started to register cases of childhood cancer. Here, we describe the incidence of cancer in children, residing in ten Mexican jurisdictions, who were treated by the Instituto Mexicano del Seguro Social (IMSS. Methods New cases of childhood cancer, which were registered prospectively in nine principal Medical Centers of IMSS during the periods 1998–2000 (five jurisdictions and 1996–2002 (five jurisdictions, were analyzed. Personnel were specifically trained to register, capture, and encode information. For each of these jurisdictions, the frequency, average annual age-standardized incidence (AAS and average annual incidence per period by sex and, age, were calculated (rates per 1,000,000 children/years. Results In total 2,615 new cases of cancer were registered, with the male/female ratio generally >1, but in some tumors there were more cases in females (retinoblastoma, germ cells tumors. The principal groups of neoplasms in seven jurisdictions were leukemias, central nervous system tumors (CNS tumors, and lymphomas, and the combined frequency for these three groups was 62.6 to 77.2%. Most frequently found (five jurisdictions was the North American-European pattern (leukemias-CNS tumors-lymphomas. Eight jurisdictions had AAS within the range reported in the world literature. The highest incidence was found for children underless than five year of age. In eight jurisdictions, leukemia had high incidence (>50. The AAS of lymphomas was between 1.9 to 28.6. Chiapas and Guerrero had the highest AAS of CNS tumors (31.9 and 30.3, respectively. The frequency and incidence of neuroblastoma was low. Chiapas had the highest incidence of retinoblastoma (21.8. Germ-cell tumors had high incidence. Conclusion The North American-European pattern of cancers was the principal one found; the overall incidence was within the range reported worldwide.

    Full Text Available Abstract Background Exacerbations of asthma are associated with viral respiratory tract infections, of which rhinoviruses (RV are the predominant virus type. Airway smooth muscle is important in asthma pathogenesis, however little is known about the potential interaction of RV and human airway smooth muscle cells (HASM. We hypothesised that rhinovirus induction of inflammatory cytokine release from airway smooth muscle is augmented and differentially regulated in asthmatic compared to normal HASM cells. Methods HASM cells, isolated from either asthmatic or non-asthmatic subjects, were infected with rhinovirus. Cytokine production was assayed by ELISA, ICAM-1 cell surface expression was assessed by FACS, and the transcription regulation of IL-6 was measured by luciferase activity. Results RV-induced IL-6 release was significantly greater in HASM cells derived from asthmatic subjects compared to non-asthmatic subjects. This response was RV specific, as 5% serum- induced IL-6 release was not different in the two cell types. Whilst serum stimulated IL-8 production in cells from both subject groups, RV induced IL-8 production in only asthmatic derived HASM cells. The transcriptional induction of IL-6 was differentially regulated via C/EBP in the asthmatic and NF-κB + AP-1 in the non-asthmatic HASM cells. Conclusion This study demonstrates augmentation and differential transcriptional regulation of RV specific innate immune response in HASM cells derived from asthmatic and non-asthmatics, and may give valuable insight into the mechanisms of RV-induced asthma exacerbations.

    Unsweetened natural cocoa powder is enriched with nutraceutical abundance of anti-asthmatic compounds theobromine and theophylline. Cocoa powder, which is prepared after removal of the cocoa butter, contains about 1.9% theobromine and 0.21% caffeine. Anecdotal reports indicate that regular consumption of unsweetened natural cocoa powder (UNCP), a common practice in Ghana, West Africa, has the potential to reduce the tendency of asthmatic episodes. In the present paper we studied the effect of regular ingestion of aqueous extract of UNCP on hematological and histopathological changes that occur in ovalbumin (OVA)-sensitized guinea pigs. OVA-sensitized guinea pigs were challenged with aerosolized OVA 1 hour after ingestion of 300 mg/kg (low dose) or 600 mg/kg (high dose) of UNCP for 35 consecutive days. Histopathological and haematological changes in the OVA-sensitized guinea pigs were evaluated. Both negative and positive controls with distilled water and prednisolone, respectively, were used. OVA-sensitized guinea pigs demonstrated concentration-independent reduction in immune response to aerosolized OVA. There were no histo-architectural changes in the bronchiolar smooth muscles of the treated groups. Unsweetened natural cocoa powder has potential anti-asthmatic properties when administered orally at the doses tested.

    It is known that the prevalence of gastroesophageal reflux disease (GERD) in asthmatic patients is high. Although an endoscopic diagnosis of GERD based on the established Los Angeles (LA) classification requires the detection of erosive mucosal breaks, there are patients with GERD who have prominent erythema of the esophageal membrane without erosive mucosal breaks. Non-erosive mucosal change denotes the minimal change of the discoloring type of reflux esophagitis. This study was undertaken to determine the prevalence of GERD in asthmatic patients using the LA classification with the inclusion of minimal change, compared to the prevalence determined using the established LA classification without minimal change. The presence of GERD in asthmatic patients (n = 78), non-asthmatic disease control patients (n = 56), and healthy subjects (n = 150) was evaluated by endoscopic examination. The frequency of GERD in asthmatic patients based on the LA classification with minimal change was higher (54/78, 69.2%) than in asthmatic patients based on the LA classification without minimal change (37/78, 47.4%) (p disease control patients (17/56, 30.4%) and healthy subjects (27/150, 18.0%) based on the LA classification with minimum change. These data indicate that asthmatic patients have a high frequency of GERD. In addition, without the inclusion of minimum change to the diagnosis of GERD, the prevalence of GERD appears to be underestimated in asthmatic patients. Therefore, physicians should carefully observe asthmatic patients with minimal change on endoscopy.

    To study the respiratory and physical health of young men, 224 asthmatic and 668 non-asthmatic military conscripts were recruited from the intake groups of July 2004 and January 2005 in Kajaani, Finland. Factors affecting respiratory health were elicited by a questionnaire at the beginning of the service, and results of high sensitive C-reactive protein (hsCRP) determination, peak expiratory flow (PEF), and 12-minute running test were collected at the beginning and the end of the service. Respiratory infections were diagnosed by a study physician. Upon entering military service, asthmatics had frequent exercise- and cold-related asthma symptoms (69.6% and 76.3%), and 48% of them had no medication for asthma. At the beginning, 25.8% of asthmatics and 19.1% of non-asthmatics had a poor result of less than 2,200 m (p = 0.05) in the 12-minute running test, and after 180 to 362 days of service, the corresponding percentages were 11.7% and 9.7% (p = 0.434). The levels of hsCRP, a marker of low-grade systemic inflammation, decreased significantly among both asthmatics, 1.5 (p = 0.001), and non-asthmatics, 1.6 mg/L (p < 0.001). Asthmatic men had 0.2 and non-asthmatics 0.1 respiratory infections per month (p < 0.001). In summary, asthmatic conscripts can enhance their physical fitness by training similarly to non-asthmatic ones. Their levels of hsCRP also decrease.

    The mean global prevalence of asthma among children is approximately 12%, making it the most common chronic disease in children. Influenza infection has been associated with complications such as exacerbations of wheezing and asthma, increased airway hyper-reactivity and hospitalization. Although influenza vaccination is recommended for asthmatic patients by all health authorities, vaccination coverage remains significantly lower than expected and is lowest of all in children. Compliance is affected by the uncertainty of parents and physicians concerning the clinical risk of influenza in asthmatic subjects, the benefits of influenza vaccination in preventing asthma exacerbations and the safety of immunization. The aim of this review is to analyze the rationale for using influenza vaccine, discuss the relationship between influenza and the severity of asthmatic episodes and document the efficacy and safety of influenza vaccination in the pediatric asthmatic population.

    The development of attenuated response ({open_quotes}tolerance{close_quotes}) to daily ozone (O{sub 3}) exposures in the laboratory is well established in healthy adult volunteers. However, the capability of asthmatics to develop tolerance during multiday ozone exposures in unclear. We exposed 10 adult volunteers with mild asthma to 0.4 ppm O{sub 3} in filtered air for 3 h/d on 5 consecutive d. Two similar filtered-air exposures during the preceding week served as controls. Follow-up O{sub 3} exposures were performed 4 and 7 d after the most recent consecutive exposure. All exposures were performed in an environmental chamber at 31 {degrees}C and 35% relative humidity. The subjects performed moderate exercise (mean ventilation rate of 32 l/min) for 15 min of each half-hour. Responses were measured with spirometry and symptom evaluations before and after each exposure, and a bronchial reactivity test (methacholine challenge) was conducted after each exposure. All response measurements showed clinically and statistically significant day-to-day variation. Symptom and forced-expiratory-volume-in-1-s responses were similarly large on the 1st and 2nd O{sub 3} exposure days, after which they diminished progressively, approaching filtered air response levels by the 5th consecutive O{sub 3} day. This tolerance was partially lost 4 and 7 d later. Bronchial reactivity peaked after the first O{sub 3} exposure and remained somewhat elevated after all subsequent O{sub 3} exposures, relative to its control level following filtered-air exposures. Individual responses varied widely; more severe initial responses to O{sub 3} predicted less rapid attenuation. We concluded that asthmatics can develop tolerance to frequent high-level O{sub 3} exposures in much the same manner as normal subjects, although the process may be slower and less fully effective in asthmatics. 27 refs., 3 figs., 4 tabs.

  5. Diabetes mellitus and insulin in an aspirin sensitive asthmatic.

    Caplin, I

    1976-03-01

    The infrequency of diabetes mellitus and asthma in the same individual is re-examined. The antagonism between epinephrine and insulin, as suggested by Konig in 1935, is indeed accurate. The assays done by the Eli Lilly Research Department revealed no in vitro effect of insulin on the CAMP and GMP level of mast cells as occurs in liver cells. It is felt that this effect is probably an in vivo effect produced via the vagus nerve and alpha-adrenergic receptor system stimulation. This would explain the mechanism of aggravation of asthma by excess insulin. Dr. Petersen's studies, the negative intradermal skin tests to insulin and the absence of change on either beef or pork insulin usage by our patient all point to a nonatopic factor in the aggravation of the asthma of this patient. In the uncommon occurrence of asthma and diabetes in the same patient, insulin dosage should be considered as a factor in all such asthmatics who do not respond well to conventional therapy. Two additional asthmatics who also have diabetes did improve with cessation of nocturnal asthma by a reduction of their evening dose of insulin. A high fat, low carbohydrate diet, as suggested by Abrahamson to avoid dietary hyperinsulinism, is certainly worth considering in patients with nocturnal asthma. If patients cannot be made to follow a diet requiring frequent feedings high in protein and fats and low in carbohydrates, another approach suggests itself. Abrahamson was able to relieve the patients who developed nocturnal asthma with hypoglycemia by having them drink a glass of milk. Assuming other causes have been eliminated and a patient awakens each day at 3:00 a.m., an alarm clock could be set at 2:00 a.m. Milk or a milk substitute in milk sensitive patients could be taken at 2:00 a.m. to raise the blood sugar and hopefully prevent the asthma associated with hypoglycemia. Also to be noted is the ubiquitous use of tartrazine in so many drugs, including those used to relieve asthmatic symptoms

    Full Text Available Background: Hereditary, environmental and developmental factors play an important role in dentofacial development, as well as the initiation of malocclusion disorder. Allergic phenomenon such as asthma that induces an alternative mode of breathing in patients is a contributing factor in development of the dental arch. Aim: Our aim in this study was to evaluate the dentoalveolar morphology in asthmatic children and to analyze the effects of asthmatic medications on the dental arch. Setting and Design : This study is centered on 44 asthmatic children aged between 6-12 years from J.S.S Hospital, Mysore. Selected variables from model analysis of the casts of the asthmatic group were subjected to comparison with those of the non-asthmatic group, which comprised of 44 non-asthmatic children. Selected parameters were arch width, arch length and palatal depth. Materials and Methods : Impressions of upper and lower arches were made with rubber based impression material. A sliding digital caliper was used to measure the casts for arch width and arch length. A palatal depth gauge was used to measure the palatal depth. Statistical Analysis : Differences in arch widths, arch lengths and palatal depths between asthmatics and non-asthmatics groups were evaluated by independent sample t-tests. Chi-square test was applied to assess the frequency of occurrence of malocclusion in the asthmatic children. Result: The results obtained revealed that the arch length and palatal depth of asthmatic group had higher values compared to that of non-asthmatic groups for both age groups (6 to 8-year-old males and females, 10 to 12-year-old males and females. Inter molar width showed a significant lower value in asthmatics in the maxillary arches of 10 to 12-year-old females. Fifty percent of the asthmatic children aged 10 to 12-years had open-bite. Children under regular medication showed significant deviation in the dentoalveolar morphology as compared to those under

    Morbidity from allergic diseases is increasing. Basophils play a critical role in systemic anaphylaxis and chronic allergic inflammation. The prenatal environment must be regarded as a possible early risk factor for allergic diseases in children. Our objective was to determine if basophils harvested from neonates genetically predisposed to atopic disease had different levels of CD63 expression and IL-4 release properties in response to various stimuli (peptidoglycan, Dermatophagoides farinae, hyperosmotic mannitol). Blood samples were collected from 16 asthmatic and 18 healthy women and their newborns. Peripheral blood basophil histamine was measured using the human basophil degranulation test (HBDT), whereas activation was assessed by flow cytometric measurement of CD63 expression on the cord blood basophil surface. IL-4 levels were quantified by ELISA following allergen stimulation. The basophil degranulation index (DI) in granulocytes harvested from the peripheral blood of asthmatic women was assessed following stimulation with peptidoglycan (PGN), Dermatophagoides farinae (Df ) extract, or hyperosmotic mannitol. The DI was significantly higher in atopic women than in healthy controls. Upregulation of CD63 on the cord blood basophil surface was also detected in response to these stimuli. Basophils purified from the cord blood of neonates born to atopic mothers produced more IL-4 compared to basophils purified from the controls. These data suggested that various stimuli play a role in augmenting allergic reactions via modulation of activated basophil cytokine secretion. It may require new methods to stabilize the basophils in allergic diseases.

    In order to explore the expression of PI-3K in T lymphocytes of asthmatic rats and the relationship between PI-3K and activation of T lymphocytes, 24 Wistar rats were randomly divided into 4 groups: normal control group, asthmatic one-week group, asthmatic two-week group and asthmatic four-week group. T cells were purified from blood of each rat and the expression of PI-3K was observed by immunocytochemical fluorescence staining, the semiquantitative fluorescence intensity was measured by HPIAS-2000 analytic software, and the expression of IL-4 in supernatants was detected by ELISA. The results showed that the fluorescence intensity of T lymphocytes in asthmatic groups was significantly higher than that in normal control (P<0.001), indicating that the expression of PI-3K in T lymphocytes of asthmatic rats was significantly higher than that in those of normal controls, and the difference between acute and chronic stage asthmatic groups was significant (P<0.05). The expression levels of IL-4 protein in supernatants of asthmatic T lymphocytes were significantly higher than those in the normal controls (P<0.05). There was a significant positive correlation between the expression of PI-3K in T lymphocytes and the IL-4 protein expression in supernatants (r=0.583, P<0.01). It was suggested that PI-3K signal pathway may participate in the processes of activation and other cytological effects of asthmatic T lymphocytes, thus may play an important roles in the pathogenesis of asthma.

    Background Effects of icariin on airway inflammation in asthmatic rats and the intervention of LPS induced inflammation are interfered with the machanism of icariin. Our study aimed to observe the effect of icariin on ovalbumin-induced imbalance of Th1/Th2 cytokine expression and its mechanism.Methods Sixty male SD rats were randomly divided into control group (PBS), asthma group (ovalbumin (OVA)-induced),dexamethasone group, and OVA+icariin low, medium and high dose groups (5, 10, 20 mg/kg, respectively). Each group had ten rats. The model of OVA sensitization was a rat asthma model. Enzyme-linked immunosorbent assay (ELISA)method was used to observe the effects of icariin on interleukin-4 (IL-4) and inerferon Y (IFN-Y) in rats' lung tissue.Immunohistochemical staining was applied to detect the intervention effects of icariin on T cells (T-bet) and gatabinding protein 3 (GATA-3) in rat pulmonary tissue. Realtime RT-PCR was used to observe the intervention effects of icariin on T-bet and GATA-3 mRNA expression in rat pulmonary tissue and spleen lymphocytes. Western blotting was used to observe the icariin intervention effects on T-bet, GATA-3 and nuclear factor-Kappa B (NF-κB) p65 protein expressions in rat pulmonary tissue.Results The ELISA results from pulmonary tissue showed that IL-4 expression was significantly reduced (P <0.05),while the IFN-y expression increased but not significantly when we compared OVA+icariin medium and high dose groups with the asthma group. Immunohistochemical staining of pulmonary tissue showed that the GATA-3 decreased significantly while the T-bet staining did not change in the OVA+icariin high dose group. In pulmonary tissue and spleen lymphocytes T-bet and GATA-3 mRNA expressions were significantly reduced (P <0.05) in icariin treatment groups compared with the asthma model group. GATA-3 and T-bet mRNA in rat spleen lymphocytes in the asthma group were higher than in the control group. GATA-3 mRNA expression in pulmonary

    The aim of this study was to systematically review the safety and efficacy of inhaled beclomethasone for asthma treatment in pregnant women. We performed a systematic review in Medline, LILACS and SciELO electronic databases in December 2012. A total of 3433 articles were found by using the keywords asthma, pregnancy and beclomethasone. Among these, 1666 were from Medline, via PubMed, and 1767 were from LILACS and SciELO. Nine of these articles were selected. Only one paper suggested an increased foetal risk for congenital malformations, and one other for offspring endocrine and metabolic disturbances. Data are mostly reassuring, supporting the use of glucocorticoid inhalants during pregnancy, and we found no evidence of inferiority in relation to efficacy and safety of beclomethasone compared to other drugs used in pregnant asthmatic women.

    A sixty-four year old man with a past history of hypercholesterolemia, asthma, food allergy, epilepsy and myocardial infarction was admitted to the emergency department because of a generalized erythema, nausea, vomiting, and chest pain after taking an oral dose of amoxicillin. Electrocardiography showed ST segment elevation in anterior leads. After coronary angiography, type 2 variant of Kounis syndrome was diagnosed. We present the first case of oral amoxicillin induced Kounis syndrome in an asthmatic patient with severe anaphylactic shock. The present report also shows that atopic people expressing an amplified mast cell degranulation may have more serious hemodynamic decompensation during hypersensitivity reactions. Case selective mast cell surface membrane stabilization should be considered a potential therapeutic strategy for people with food induced allergy, for atopic patients and for patients who have already experienced a first Kounis syndrome.

    Therapeutic effects of Portulaca oleracea for respiratory diseases are indicated in ancient Iranian medical books. The relaxant effect of this plant have also been observed on smooth muscle tissue in previous studies. Therefore, in the present study, the bronchodilatory effect of the boiled extract of Portulaca oleracea in the airway of asthmatic patients was examined. The relaxant effect of the orally administered 0.25 ml/kg of 5% boiled extract in comparison with 3 mg/kg oral theophylline and 200 microg inhaled salbutamol was studied by measuring forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), maximal mid-expiratory flow (MEF(25-75)), and specific airway conductance (sGaw). The FEV1, PEF, MEF(25-75), and sGaw were measured before, administration and repeated 15, 30, 60, 90, and 120 min after administration of the oral extract and theopylline. For inhaled salbutamol measurements were performed 5, 15, 30, and 60 min post-inhalation. Results showed that the boiled extract of Portulaca oleracea caused significant increases in all measured pulmonary function tests (PFTs), (P < 0.05 to P < 0.01). There was no significant difference between the maximum increase in measured PFTs due to the boiled extract and theophylline. However, maximum increase in PEF and MEF(25-75) due to the boiled extract were significantly lower than those of salbutamol (P < 0.05 for both cases). The onset of brochodilatory effect of extract was similar to that of theophylline beginning 60 min, but the effect of extract decline after 120 min after administration. In conclusion, the results of the present study showed that Portulaca oleracea has a relatively potent but transient bronchodilatory effect on asthmatic airways.

    Hyperplasia of airway smooth muscle (ASM) is a feature of the remodelled airway in asthmatics. We examined the antiproliferative effectiveness of the corticosteroid dexamethasone on expression of the key regulator of G(1) cell cycle progression-cyclin D1-in ASM cells from nonasthmatics and asthmatics stimulated with the mitogen platelet-derived growth factor BB. While cyclin D1 mRNA and protein expression were repressed in cells from nonasthmatics in contrast, cyclin D1 expression in asthmatics was resistant to inhibition by dexamethasone. This was independent of a repressive effect on glucocorticoid receptor translocation. Our results corroborate evidence demonstrating that corticosteroids inhibit mitogen-induced proliferation only in ASM cells from subjects without asthma and suggest that there are corticosteroid-insensitive proliferative pathways in asthmatics.

    Disodium cromoglycate is an anti-asthmatic drug that has mast cell-stabilizing effects and other anti-inflammatory effects. However, the mechanisms of its anti-inflammatory effects are unclear. In this study, we evaluated effects of disodium cromoglycate on eosinophilia, early and late asthmatic responses, and production of arachidonic acid metabolites in guinea pig lungs. Guinea pigs were alternately sensitized and challenged by exposure to mists of ovalbumin+Al(OH)(3) and ovalbumin, respectively. Disodium cromoglycate (0.5-2 mg/0.1 ml/animal) administered intratracheally before the fifth challenge dose-dependently inhibited asthmatic response, but early asthmatic response was not affected. Disodium cromoglycate at 2 mg/animal potently suppressed increases in cysteinyl leukotrienes (CysLTs) and thromboxane A(2) in the lung during late asthmatic response. Eosinophilia was slightly reduced by disodium cromoglycate. The inhibitory effect of disodium cromoglycate on late asthmatic response is apparently due to inhibition of the release of arachidonic acid metabolites, some of which may be derived from eosinophils that infiltrate the lung.

    Full Text Available Asthma is the most common chronic disease of childhood. It is known that asthma prevalence has increased significantly especially in children in last 20 years. To stop this increase in asthma, causes and prevention measures should be known better. For the management of the illness, control of environmental and trigger factors causing asthma attack are extremely important. Asthmatic children and family should be informed by health staff about changes in their life and measures to prevent the attacks. Through this information asthmatic children and their families can be supported for a better quality of life. [TAF Prev Med Bull 2010; 9(1.000: 79-86

    The mechanical alterations related to the excessive use of accessory respiratory muscles and the mouth breathing observed in children with asthma may lead to the development of alterations in head posture, shoulders, thoracic region and, consequently, in alterations of body posture. The purpose of this study was to assess body posture changes of children with asthma compared to a non-asthmatic control group matched for gender, age, weight, and height. Thirty children with asthma and 30 non-asthmatic children aged 7 to 12 years were enrolled in this study. Digital photographic records were obtained for analysis of the body posture of the children by computed photogrammetry. The intraclass correlation coefficient and Student's t test (p postural alterations compared to non-asthmatic controls since the only angle for which there was a significant difference between groups showed weak reproducibility. The findings of this study do not support the notion that children with asthma present alterations in body posture.

    Providing hepatitis B vaccine to all neonates within 24 hours of birth (Timely Birth Dose, TBD) is the key preventative measure to control perinatal hepatitis B virus infection. Previous Chinese studies of TBD only differentiated between migrant and non-migrant (local-born generation-LG) children. Our study is the first to stratify migrants in Beijing into first generation migrants (FGM) and second generation migrants (SGM). Based on a questionnaire survey of 2682 people in 3 Beijing villages, we identified 283 children aged 0-15 years, from 246 households, who were eligible for a TBD. Multinomial logistic regression and statistical analyses were used to examine factors explaining TBD rates for LG, FGM and SGM children. Surprisingly, the TBD for LG Beijing children was not significantly different from migrant children. But after stratifying migrant children into FGM and SGM, revealed significant TBD differences were revealed across LG, FGM and SGM according to domicile (p-value Hukou reform to improve SGM TBD; and called for Beijing health authorities to match TBD rates in other provinces, especially by improving practices by health authorities and knowledge of parents.

  11. Barrier disrupting effects of alternaria alternata extract on bronchial epithelium from asthmatic donors.

    Directory of Open Access Journals (Sweden)

    Marina S Leino

    Full Text Available Sensitization and exposure to the allergenic fungus Alternaria alternata has been associated with increased risk of asthma and asthma exacerbations. The first cells to encounter inhaled allergens are epithelial cells at the airway mucosal surface. Epithelial barrier function has previously been reported to be defective in asthma. This study investigated the contribution of proteases from Alternaria alternata on epithelial barrier function and inflammatory responses and compared responses of in vitro cultures of differentiated bronchial epithelial cells derived from severely asthmatic donors with those from non-asthmatic controls. Polarised 16HBE cells or air-liquid interface (ALI bronchial epithelial cultures from non-asthmatic or severe asthmatic donors were challenged apically with extracts of Alternaria and changes in inflammatory cytokine release and transepithelial electrical resistance (TER were measured. Protease activity in Alternaria extracts was characterised and the effect of selectively inhibiting protease activity on epithelial responses was examined using protease inhibitors and heat-treatment. In 16HBE cells, Alternaria extracts stimulated release of IL-8 and TNFα, with concomitant reduction in TER; these effects were prevented by heat-treatment of the extracts. Examination of the effects of protease inhibitors suggested that serine proteases were the predominant class of proteases mediating these effects. ALI cultures from asthmatic donors exhibited a reduced IL-8 response to Alternaria relative to those from healthy controls, while neither responded with increased thymic stromal lymphopoietin (TSLP release. Only cultures from asthmatic donors were susceptible to the barrier-weakening effects of Alternaria. Therefore, the bronchial epithelium of severely asthmatic individuals may be more susceptible to the deleterious effects of Alternaria.

Bronquial asthma is a high frequency desease, and it requires an evaluated attention. Objective: to evaluate the medical attention to the asthmatic patient in the Area III polyclinic of Cienfuegos. Methods: Transversal and descriptive study that included 150 patients randomly selected from the dispensary records of the Area III Educational Polyclinic of Cienfuegos, in December 2001. Medical records were checked and the patients were interviewed. Results: differences were found among the classifications (light, persistent and moderate reflected in medical records and the evaluation the authors made. Only 12 % of the Medical Records had good quality. The 80 % of patients have adequate knowledge about their desease, but most of them do not follow inter-crisis treatment. The place more used for treatment of the crisis was the polyclinic. There is a high level of satisfaction with medical services. Conclusion: The medical care of patient with bronchial asthma can be improved, being more systematic in inter-crisis treatment based on previous evaluation of each patient and in the sequential use of different therapeutic options, particularly in the practice of correct life styles.

  13. The Difficult-to-Control Asthmatic: A Systematic Approach

    2006-09-01

    Full Text Available Abstract With the judicious use of inhaled corticosteroids, β2 agonists, and leukotriene modifiers, most patients with asthma are easily controlled and managed. However, approximately 5% of asthmatics do not respond to standard therapy and are classified as "difficult to control." 1 Typically, these are patients who complain of symptoms interfering with daily living despite long-term treatment with inhaled corticosteroids in doses up to 2,000 μg daily. Many factors can contribute to poor response to conventional therapy, and especially for these patients, a systematic approach is needed to identify the underlying causes. First, the diagnosis of asthma and adherence to the medication regimen should be confirmed. Next, potential persisting exacerbating triggers need to be identified and addressed. Concomitant disorders should be discovered and treated. Lastly, the impact and implications of socioeconomic and psychological factors on disease control can be significant and should be acknowledged and discussed with the individual patient. Less conventional and novel strategies for treating corticosteroid-resistant asthma do exist. However, their use is based on small studies that do not meet evidence-based criteria; therefore, it is essential to sort through and address the above issues before reverting to other therapy.

    Full Text Available Introduction: Air pollution, perfume, aerosol substances, odors of paint and detergent are the most important non-specific irritants stimulating the asthmatic attack. The odors of these substances exist for long time and form the serious risk for the asthmatic patients. This study was planned to determine the frequency of using perfume and substance containing perfume and the sensitivities to the substances among the asthmatic patients using inhaling steroid and b2-mimetic ant asthmatic drugs. Methods: This is a descriptive study and conducted among patients who applied to the Allergic Diseases outpatient service of Gulhane Military Medical Academia in October-December 2004. 83 asthmatic patients who accepted to participate to the study filled out a questionnaire that including patients habits relating perfume, cleaners with perfume, perfume for living room, toilets and bathrooms, and having dyspnea or not when exposed any kind of perfumes and using any b2-mimetik or not. Results: 73.5% (n=61 of participants were male, and 26.5 % (n=22 were women. Their ages were from 18 to 57 years. 79.5% (n=66 of participants expressed that they were sensitive to the odors mentioned and experienced the respiratory problems when they were at the surroundings by odour and 26.5% (n=22 of participants sometimes used the B2-mimetic antiasthmatic drugs for this reason. On the other hand; It was found that 68.7% (n=57 of participants regularly used the perfume for themselves everyday, 85.5% (n=71 of participants washed their clothings by using cleaners and/or softeners with perfume, 44.6% (n=37 of participants used the perfume for their rooms frequently, 62.7% (n=52 of participants used substance with perfume in their toilets and bathrooms. Conclusion: We conclude that the asthmatic patients have not sufficient knowledge about non-spesific irritants stimulating the asthmatic attack, and don’t behave sensitive. It’s important to plan properly the medical

    Full Text Available Steroid resistance is a significant problem in management of chronic inflammatory diseases, including asthma. Accessible biomarkers are needed to identify steroid resistant patients to optimize their treatment. This study examined corticosteroid resistance in severe asthma. 24 asthmatics with forced expiratory volume in one second of less then 80% predicted were classified as steroid resistant or steroid sensitive based on changes in their lung function following a week of treatment with oral prednisone. Heparinised blood was collected from patients prior to oral prednisone administration. Phosphorylated mitogen activated kinases (MAPK (extracellular regulated kinase (ERK, p38 and jun kinase (JNK were analyzed in whole blood samples using flow cytometry. Activation of phospho-p38 MAPK and phospho-mitogen- and stress-activated protein kinase 1 (MSK1 in asthmatics' peripheral blood mononuclear cells (PBMC were confirmed by Western blot. Dexamethasone suppression of the LPS-induced IL-8 mRNA production by steroid resistant asthmatics PBMC in the presence of p38 and ERK inhibitors was evaluated by real time PCR. Flow cytometry analysis identified significantly stronger p38 phosphorylation in CD14+ monocytes from steroid resistant than steroid sensitive asthmatics (p = 0.014, whereas no difference was found in phosphorylation of ERK or JNK in CD14+ cells from these two groups of asthmatics. No difference in phosphorylated p38, ERK, JNK was detected in CD4+, CD8+ T cells, B cells and NK cells from steroid resistant vs. steroid sensitive asthmatics. P38 MAPK pathway activation was confirmed by Western blot, as significantly higher phospho-p38 and phospho-MSK1 levels were detected in the PBMC lysates from steroid resistant asthmatics. P38 inhibitor significantly enhanced DEX suppression of LPS-induced IL-8 mRNA by PBMC of steroid resistant asthmatics. This is the first report demonstrating selective p38 MAPK pathway activation in blood monocytes of

    Bronchial asthma is an intercurrent disease that affects a major portion of the population. Neither its etiopathogenesis nor its complications have been fully established. The purpose of this study was to determine the composition of oropharyngeal bacterial flora in asthmatic patients and compare it with oropharyngeal bacterial flora in a group of healthy patients in order to establish its relationship with the pathogenesis of asthma and its complications. A sample consisting of 116 pharyngeal swabs was analysed from march 1995 to december 1996. 58 of the total amount of pharyngeal swabs corresponded to asthmatic patients (during asthmatic crisis), while the other 58 corresponded to healthy subjects. Common bacteriological culture techniques were carried out in order to obtain the bacteriological diagnosis. The results showed that isolation of transitory flora bacteria in asthmatic patients was 75.8%, which was significantly higher (p crisis. This data must be considered when applying empiric therapy in asthmatic patients complicated with pneumonia. The possibility that certain infectious agents, including bacteria, could play a role in asthma pathogenesis is one of the questions that should be answered in future studies on this topic.

    Acute Chlamydia pneumoniae infection may initiate asthma or worsen asthmatic symptoms. In crowded conditions, such as military service, young men are susceptible to respiratory infections, including C. pneumoniae. We recruited 127 asthmatic and 391 nonasthmatic military conscripts, followed up their respiratory tract infections and the kinetics of serum C. pneumoniae antibodies, and assessed the association between C. pneumoniae and asthma during 6 months of military service in 2 intake groups. During the 6-month period, in the July intake group, IgG antibody prevalence decreased from 60.3% to 43.8% in asthmatic and from 55.6% to 22.6% in nonasthmatic conscripts. In the January intake group, IgG antibody prevalence increased from 38.3% to 48.4% in asthmatic and from 37.2% to 43% in nonasthmatic recruits. IgG and IgA antibodies persisted more often in the asthmatic groups. In conclusion, the prevalence of IgG antibodies showed seasonal variation. Military recruits seem to be most vulnerable to C. pneumoniae infections during the period from January to June. The antibody titer changes were more rapid than previously thought.

    For children to receive needed oral health care, adequate training at both the predoctoral and postdoctoral levels of dental education is required, but previous studies have found inadequacies in predoctoral education that lead to general dentists' unwillingness to treat certain young populations. As another way of assessing predoctoral preparation, the aim of this study was to determine the perspectives of first-year residents and pediatric program directors about residents' preparedness to enter advanced education programs in pediatric dentistry. Surveys were sent to all 74 U.S. program directors and 360 first-year residents. The survey focused on procedures related to prevention, behavior management, restorative procedures, pulp therapy, sedation, and surgery, as well as treating patients funded by Medicaid and with special health care needs. Among the first-year residents, 173 surveys were returned for a 48% response rate; 61 directors returned surveys for an 82% response rate. Only half of the residents (55%) reported feeling adequately prepared for their first year in residency; less than half cited adequate preparation to place stainless steel crowns (SSCs) (42%) and perform pulpotomies (45%). Far fewer felt adequately prepared to provide treatment for children six months to three years of age, including examinations (29%), infant oral exams (27%), and children with severe caries (37%). The program directors were even less positive about the adequacy of residents' preparation. Only 17% deemed them adequately prepared to place SSCs and 13% to perform pulpotomies. Approximately half reported their first-year residents were inadequately prepared to treat very young children and children with severe caries (55% each). This study found that the perceived inadequacy of predoctoral education in pediatric dentistry was consistent at both the learner and educator levels, supporting previous studies identifying inadequacies in this area.

    Full Text Available Objective: The present study evaluated the prevalence of anaemia and its determinants in one- and three-year-old children from the Capricorn District of Limpopo Province, South Africa. Methods: A prospective cohort study conducted in rural villages in the Capricorn District of Limpopo Province, South Africa. At birth, a cohort of 219 children was followed until they were one and three years of age. Data collected included the children’s anthropometric measurements, blood for biochemical analysis (full blood count, ferritin, folate and vitamin B12 and socio-demographic status.Results: At one year, anaemia (Hb < 11 g/dL was present in 52% of the children, decreasing to 22% by the third year. Iron deficiency (ferritin < 12 µg/mL was common in these children (39% and 33% at one year and three years, respectively particularly in the presence of anaemia. Folate and vitamin B12 deficiencies (< 5 ng/mL and < 145 pg/mL, respectively were common at one year, with the children accumulating enough vitamin B12 by three years; however, folate deficiency levels remained fairly constant between the two time points.Conclusion: There was a high prevalence of anaemia in the study participants at one year and three years of age. Factors that increased the risk of anaemia at three years were: a mother with only a primary school education, anaemia at one year, male gender, overweight, and combined overweight and stunting. Protective factors against anaemia were having a younger mother who served as the main caregiver.

    Recently, countries at high latitudes have updated their vitamin D recommendations to ensure adequate intake for the musculoskeletal health of their respective populations. In 2010, the dietary guidelines for vitamin D for Canadians and Americans aged 1-70 years increased from 5 μg/d to 15 μg/d, whereas in 2016 for citizens of the UK aged ≥4 years 10 μg/d is recommended. The vitamin D status of Canadian children following the revised dietary guidelines is unknown. Therefore, this study aimed to assess the prevalence and determinants of vitamin D deficiency and sufficiency among Canadian children. For this study, we assumed serum 25-hydroxy vitamin D (25(OH)D) concentrations D deficient and 71 % were vitamin D sufficient. Children who consumed vitamin D-fortified milk daily (77 %) were more likely to be sufficient than those who consumed it less frequently (OR 2·7; 95 % CI 1·4, 5·0). The 9 % of children who reported taking vitamin D-containing supplements in the previous month had higher 25(OH)D concentrations (OR 6·9 nmol/l; 95 % CI 1·1, 12·7 nmol/l) relative to those who did not. Children who were older, obese, of non-white ethnicity and from low-income households were less likely to be vitamin D sufficient. To improve vitamin D status, consumption of vitamin D-rich foods should be promoted, and fortification of more food items or formal recommendations for vitamin D supplementation should be considered.

    Nursing residents may experience physical and emotional exhaustion from the daily life of attending the Program. The aim of this study was to determine the Burnout incidence among Nursing Residents. An investigative, descriptive, analytical, longitudinal-prospective study was conducted with 16 Residents over two years. The Maslach Burnout Inventory was used, translated and validated for Brazil, as well as a sociodemographic/occupational data tool. Of all residents, 17.2% showed high rates in Emotional Exhaustion and Depersonalization; 18.8% showed impaired commitment in Personal Accomplishment, 75% of which belonged to specialty areas, such as Emergency Nursing, Adult and Pediatric Intensive Care. Age and specialty area were positively correlated with Personal Accomplishment. One of the Residents was identified with changes in three subscales of the Maslach Burnout Inventory, thus characterized as a Burnout Syndrome patient. Nursing Residents have profiles of disease. Knowing these factors can minimize health risks of these workers.

    The problem of educative charge of the asthmatic patient has mobilised general physicians, specialists and kinesitherapists for many years. The first mutual aid associations for asthmatic patients, created at the initiative of pneumologists and allergists or their patients date back for a score or so of years and their principal objectives are the adaption of educational measures, in transmission of clear information and in the loan of surveillance equipment, to ensure that inhalation equipment is adapted appropriately to the case. Since, the mediatisation has reinforced this action in all directions, in the interests of and for the great benefit of asthmatic patients; and so the role of the pharmacist has also become essential not only in the field of information but also in that of control of the self-evaluation of the patient; three inseparable aspects are thus emphasized: information aspect, technical aspect, initiation of surveillance of the illness.

    In asthmatic mice, dexamethasone (30.0 mg/kg) was administered orally once daily on Days 24-27. One hour after dexamethasone on Day 25-27, the mice were exposed to ovalbumin aerosols. Twenty-eight days after the initial ovalbumin immunization, we found that dexamethasone reduced methacholine-induced pulmonary gas trapping and inhibited bronchoalveolar lavage eosinophils and neutrophils. However, five days after the last dose of dexamethasone and last ovalbumin aerosol exposure in other asthmatic mice, the airway obstructive response to methacholine was exacerbated in dexamethasone-treated mice compared to vehicle-treated mice on Day 32. Further, eosinophils, but not neutrophils, were still inhibited after cessation of dexamethasone. Thus, discontinuing dexamethasone worsened methacholine-induced pulmonary gas trapping of asthmatic mice in the absence of eosinophilic airway inflammation.

    Full Text Available Abstract Background Laminins are a group of proteins largely responsible for the anchorage of cells to basement membranes. We hypothesized that altered Laminin chain production in the bronchial mucosa might explain the phenomenon of epithelial cell shedding in asthma. The aim was to characterize the presence of Laminin chains in the SEBM and epithelium in allergic and non-allergic asthmatics. Patients and methods Biopsies were taken from the bronchi of 11 patients with allergic and 9 patients with non-allergic asthma and from 7 controls and stained with antibodies against the Laminin (ln chains alpha1-alpha5, beta1-beta2 and gamma1-gamma2. Results Lns-2,-5 and -10 were the main Laminins of SEBM. The layer of ln-10 was thicker in the two asthmatic groups while an increased thickness of lns-2 and -5 was only seen in allergic asthmatics. The ln gamma2-chain, which is only found in ln 5, was exclusively expressed in epithelial cells in association with epithelial injury and in the columnar epithelium of allergic asthmatics. Conclusion The uncoordinated production of chains of ln-5 in allergic asthma could have a bearing on the poor epithelial cell anchorage in these patients.

    Bronchospasm induced in non-asthmatic human subjects can be easily reversed by a deep inspiration (DI) whereas bronchospasm that occurs spontaneously in asthmatic subjects cannot. This physiological effect of a DI has been attributed to the manner in which a DI causes airway smooth muscle (ASM) cells to stretch, but underlying molecular mechanisms–and their failure in asthma–remain obscure. Using cells and tissues from wild type and zyxin-/- mice we report responses to a transient stretch of physiologic magnitude and duration. At the level of the cytoskeleton, zyxin facilitated repair at sites of stress fiber fragmentation. At the level of the isolated ASM cell, zyxin facilitated recovery of contractile force. Finally, at the level of the small airway embedded with a precision cut lung slice, zyxin slowed airway dilation. Thus, at each level zyxin stabilized ASM structure and contractile properties at current muscle length. Furthermore, when we examined tissue samples from humans who died as the result of an asthma attack, we found increased accumulation of zyxin compared with non-asthmatics and asthmatics who died of other causes. Together, these data suggest a biophysical role for zyxin in fatal asthma. PMID:28278518

    Full Text Available Introduction: Ramadan is the 9th Islamic lunar month during which Muslims avoid eating and drinking from sunrise to sunset. The effect of Ramadan intermittent fasting on asthma control is controversial. The aim of this study was to investigate the effects of Ramadan fasting on the spirometric variables and clinical symptoms on well-controlled asthmatic patients during Ramadan. Material and Methods: a cohort study was conducted in Mashhad, Khorasan Razavi, Iran. Twenty-nine (19 females and 10 males well-controlled asthmatic patients aged 47 (12 years completed the study. The average duration of fasting was 26.5 days. Assessment of spirometric variables (daily peak expiratory flow, peak expiratory flow variability, peak expiratory flow home monitoring as well as asthma clinical symptoms including dyspnea, cough, wheezing, and chest tightness were carried out. Results: No significant changes in clinical symptoms were reported in asthmatic patients at the end of Ramadan fasting. Among spirometric variables, only peak expiratory flow improved after Ramadan (p <0.05. There was a reduction in the mean peak expiratory flow variability from 13% at the first week of fasting to 10% at the fourth week (p <0.05. Conclusion: In well-controlled asthmatic patients, Ramadan fasting resulted in improvement in peak expiratory flow and peak expiratory flow variability.

    Severe asthmatics are characterized by alterations of bifurcation angle, hydraulic diameter, circularity of the airways, and local shift of air-volume functional change. The characteristics altered against healthy human subjects can affect flow structure and particle deposition. A large-eddy-simulation (LES) model for transitional and turbulent flows is utilized to study flow characteristics and particle deposition with representative healthy and severe asthmatic lungs. For the subject-specific boundary condition, local air-volume changes are derived with two computed tomography images at inspiration and expiration. Particle transport simulations are performed on LES-predicted flow fields. In severe asthmatics, the elevated air-volume changes of apical lung regions affect the increased particle distribution toward upper lobes, especially for small particles. The constricted airways are significantly correlated with high wall shear stress, leading to the increased pressure drop and particle deposition. The structural alterations of bifurcation angle, circularity and hydraulic diameter in severe asthmatics are associated with the increase of particle deposition, wall shear stress and wall thickness.

    Michel, O; Ginanni, R; Sergysels, R

    1995-11-01

    Lipopolysaccharides (LPS, the major part of endotoxins) are bacterial proinflammatory substances which can induce in asthmatic patients after inhalation a bronchial obstruction with an increase in both histamine bronchial hyperresponsiveness and blood inflammatory markers. The aim of the present study was to evaluate whether an acute inhalation of sodium cromoglycate, an anti-inflammatory and membrane-stabilizating agent, can block the LPS-induced lung function response. Using a double-blind placebo-controlled crossover method, 7 asthmatic subjects were submitted, at 4 days' interval, to a bronchial challenge test with either solvent solution or LPS (20 micrograms) preceded by inhalation of sodium cromoglycate (10 mg) or placebo. Compared to the solvent reaction, LPS induced a significant bronchial obstruction [measured by both the forced expiratory volume in 1 s (FEV1) and the airway resistances] beginning at the 60th minute and lasting more than 300 min (p sodium cromoglycate significantly inhibited the LPS-induced bronchial obstruction. The total lung capacity did not change significantly after LPS inhalation. Thus, this study showed that in asthmatics the LPS-induced FEV1 response is blocked by acute treatment with sodium cromoglycate. Sodium cromoglycate could be an active treatment in asthmatics exposed to house dust containing endotoxin.

    2003-01-01

    Objective: To investigate the distribution and recruitment of pulmonary dendritic cells (DCs) and the influence of low dosage arsenic trioxide (As2O3) on them in the airway of asthmatic mice. Methods: Thirty BALB/c mice were randomly divided into 3 groups: the control group, the asthmatic group and the As2O3 treated group. The mice asthmatic model was induced via sensitizing with peritoneal injection of ovalbumin (OVA) for two times and then provocated with aerosol inhalation of OVA for a week. The treated group was peritoneally injected with 0.2 ml solution of As2O3 (4mg/kg) 0.5h after each provocation. The immunohistochemistry and computerised image analysis were applied to detect quantitatively the DCs in the lung and airway of mice. Results: All intraepithelial nonlymphoid dendritic cells-145 (NLDC-145) throughout the respiratory tree in the mice of the control group formed a network with the density of DCs varying from (575±54) cells/mm2 epithelial surface in the large airway, to (68±12) cells/mm2 epithelial surface in the small airway. The distribution of airway NLDC-145+ in the asthmatic group was similar to that in the control group, but its density was significantly upregulated (P<0.01). The distribution of airway NLDC-145 in the treated group was similar to that in the asthmatic group, only its density was significantly downregulated (P<0.01). Conclusion: There is an integral network of NLDC-145+ throughout the respiratory tree. To downregulate the density but not change the distribution of pulmonary DCs could be an important therapeutic mechanism of low dosage As2O3 in treating asthma.

    Susanna L Lundström

    Full Text Available BACKGROUND: Asthma is a chronic inflammatory lung disease that causes significant morbidity and mortality worldwide. Air pollutants such as particulate matter (PM and oxidants are important factors in causing exacerbations in asthmatics, and the source and composition of pollutants greatly affects pathological implications. OBJECTIVES: This randomized crossover study investigated responses of the respiratory system to Stockholm subway air in asthmatics and healthy individuals. Eicosanoids and other oxylipins were quantified in the distal lung to provide a measure of shifts in lipid mediators in association with exposure to subway air relative to ambient air. METHODS: Sixty-four oxylipins representing the cyclooxygenase (COX, lipoxygenase (LOX and cytochrome P450 (CYP metabolic pathways were screened using liquid chromatography-tandem mass spectrometry (LC-MS/MS of bronchoalveolar lavage (BAL-fluid. Validations through immunocytochemistry staining of BAL-cells were performed for 15-LOX-1, COX-1, COX-2 and peroxisome proliferator-activated receptor gamma (PPARγ. Multivariate statistics were employed to interrogate acquired oxylipin and immunocytochemistry data in combination with patient clinical information. RESULTS: Asthmatics and healthy individuals exhibited divergent oxylipin profiles following exposure to ambient and subway air. Significant changes were observed in 8 metabolites of linoleic- and α-linolenic acid synthesized via the 15-LOX pathway, and of the COX product prostaglandin E(2 (PGE(2. Oxylipin levels were increased in healthy individuals following exposure to subway air, whereas asthmatics evidenced decreases or no change. CONCLUSIONS: Several of the altered oxylipins have known or suspected bronchoprotective or anti-inflammatory effects, suggesting a possible reduced anti-inflammatory response in asthmatics following exposure to subway air. These observations may have ramifications for sensitive subpopulations in urban areas.

    Uncontrolled asthma is a risk factor for pregnancy-related complications. Hyaluronic acid (HA), a potential peripheral blood marker of tissue fibrosis in various diseases, promotes eosinophil survival and plays a role in asthmatic airway inflammation as well as in physiological processes necessary to maintain normal pregnancy; however the level of circulating HA in asthma and asthmatic pregnancy is unknown. We investigated HA levels in asthmatic patients (N = 52; asthmatic pregnant (AP) N = 16; asthmatic non-pregnant (ANP) N = 36) and tested their relationship to asthma control. Serum HA level was lower in AP than in ANP patients (27 [24.7-31.55] vs. 37.4 [30.1-66.55] ng/mL, p = 0.006); the difference attenuated to a trend after its adjustment for patients' age (p = 0.056). HA levels and airway resistance were positively (r = 0.467, p = 0.004), HA levels and Asthma Control Test (ACT) total score inversely (r = -0.437, p = 0.01) associated in ANP patients; these relationships remained significant even after their adjustments for age. The potential value of HA in the determination of asthma control was analyzed using ROC analysis which revealed that HA values discriminate patients with ACT total score ≥20 (controlled patients) and asthma control, as it correlates with airway resistance and has good sensitivity in the detection of impaired asthma control. Decrease of HA level in pregnancy may be the consequence of pregnancy induced immune tolerance.

    Full Text Available Obesity as a common health risk is increasing all over the world. The aim of this study was evaluation of standing and sitting positions on spirometric values in obese asthmatic patients, in comparison with normal obese subjects.The study included 49 obese asthmatic patients with mean age of 42.63 years and body mass index of 36.06 kg/m2, and 51 control obese normal subjects with mean age of 39.86 years and body mass index of 36.69 kg/m2. Subjects with body mass index of (BMI ≥30 kg/m2  were enrolled in the study. Spirometric values were measured according to American Thoracic Society (ATS recommendation. In both groups forced vital capacity (FVC and forced expiratory volume in 1 second (FEV1 were measured in sitting and standing positions, and the results were compared.The mean±SD of FVC in sitting and standing positions in obese asthmatic patients were: 3.04±0.93 lit and 3.03±0.96lit, p=0.37; and in control group: 3.68±1.12 lit and 3.72± 1.11 lit, p=0.39, respectively. The mean±SD of FEV1 in the sitting position and standing positions in obese asthmatic patients were: 2.38± 0.75 lit and 2.40± 0.81 lit, p=0.20; and in control subjects: 3.17± 0.92 lit and 3.21± 0.93 lit, p=0.07.This study showed that spirometric values in obese asthmatic patients with BMI≥30 are not affected by the standing and sitting positions.

  8. Cigarette smoke causes caspase-independent apoptosis of bronchial epithelial cells from asthmatic donors.

    Directory of Open Access Journals (Sweden)

    Fabio Bucchieri

    Full Text Available Epidemiologic studies have demonstrated important links between air pollution and asthma. Amongst these pollutants, environmental cigarette smoke is a risk factor both for asthma pathogenesis and exacerbation. As the barrier to the inhaled environment, the bronchial epithelium is a key structure that is exposed to cigarette smoke.Since primary bronchial epithelial cells (PBECs from asthmatic donors are more susceptible to oxidant-induced apoptosis, we hypothesized that they would be susceptible to cigarette smoke-induced cell death.PBECs from normal and asthmatic donors were exposed to cigarette smoke extract (CSE; cell survival and apoptosis were assessed by fluorescence-activated cell sorting, and protective effects of antioxidants evaluated. The mechanism of cell death was evaluated using caspase inhibitors and immunofluorescent staining for apoptosis-inducing factor (AIF.Exposure of PBEC cultures to CSE resulted in a dose-dependent increase in cell death. At 20% CSE, PBECs from asthmatic donors exhibited significantly more apoptosis than cells from non-asthmatic controls. Reduced glutathione (GSH, but not ascorbic acid (AA, protected against CSE-induced apoptosis. To investigate mechanisms of CSE-induced apoptosis, caspase-3 or -9 inhibitors were tested, but these failed to prevent apoptosis; in contrast, CSE promoted nuclear translocation of AIF from the mitochondria. GSH reduced the number of nuclear-AIF positive cells whereas AA was ineffective.Our results show that PBECs from asthmatic donors are more susceptible to CSE-induced apoptosis. This response involves AIF, which has been implicated in DNA damage and ROS-mediated cell-death. Epithelial susceptibility to CSE may contribute to the impact of environmental tobacco smoke in asthma.

    The transcription factor PU.1 is involved in regulation of macrophage differentiation and maturation. However, the role of PU.1 in alternatively activated macrophage (AAM) and asthmatic inflammation has yet been investigated. Here we report that PU.1 serves as a critical regulator of AAM polarization and promotes the pathological progress of asthmatic airway inflammation. In response to the challenge of DRA (dust mite, ragweed, and Aspergillus) allergens, conditional PU.1-deficient (PU/ER(T)(+/-)) mice displayed attenuated allergic airway inflammation, including decreased alveolar eosinophil infiltration and reduced production of IgE, which were associated with decreased mucous glands and goblet cell hyperplasia. The reduced asthmatic inflammation in PU/ER(T)(+/-) mice was restored by adoptive transfer of IL-4-induced wild-type (WT) macrophages. Moreover, after treating PU/ER(T)(+/-) mice with tamoxifen to rescue PU.1 function, the allergic asthmatic inflammation was significantly restored. In vitro studies demonstrate that treatment of PU.1-deficient macrophages with IL-4 attenuated the expression of chitinase 3-like 3 (Ym-1) and resistin-like molecule alpha 1 (Fizz-1), two specific markers of AAM polarization. In addition, PU.1 expression in macrophages was inducible in response to IL-4 challenge, which was associated with phosphorylation of signal transducer and activator of transcription 6 (STAT6). Furthermore, DRA challenge in sensitized mice almost abrogated gene expression of Ym-1 and Fizz-1 in lung tissues of PU/ER(T)(+/-) mice compared with WT mice. These data, all together, indicate that PU.1 plays a critical role in AAM polarization and asthmatic inflammation.

  10. Airway protease/antiprotease imbalance in atopic asthmatics contributes to increased Influenza A virus cleavage and replication

    Directory of Open Access Journals (Sweden)

    Kesic Matthew J

    2012-09-01

    Full Text Available Abstract Asthmatics are more susceptible to influenza infections, yet mechanisms mediating this enhanced susceptibility are unknown. Influenza virus hemagglutinin (HA protein binds to sialic acid residues on the host cells. HA requires cleavage to allow fusion of the viral HA with host cell membrane, which is mediated by host trypsin-like serine protease. We show data here demonstrating that the protease:antiprotease ratio is increased in the nasal mucosa of asthmatics and that these changes were associated with increased proteolytic activation of influenza. These data suggest that disruption of the protease balance in asthmatics enhances activation and infection of influenza virus.

Methods: Subjects were evaluated for allelic frequencies of the β2-adrenergic receptor gene, height, weight, body mass index (BMI, BMI Z-score, waist circumference (WC, pubertal stage, resting heart rate (HRres, blood pressure (BP, total cholesterol (TC, glucose, insulin, high density lipoprotein (HDL-C, low density lipoprotein (LDL-C, triglyceride (TG, Homeostasis Metabolic Assessment (HOMA2-IR, Quantitative Insulin Sensitivity Check Index (QUICKI and maximal oxygen uptake (VO2max. The participants were divided in four groups: overweight asthmatic (n=39, overweight non-asthmatic (n=115, normal weight asthmatic (n=12, and normal weight non-asthmatic (n=40. Results: Regarding the Gln27Glu polymorphism, higher total cholesterol was observed in usual genotype individuals than in genetic variant carriers (p=0.04. No evidence was found that the evaluated polymorphisms are influencing the physical fitness. The Arg16 allele was found more frequently among the normal weight asthmatic group when compared to the normal weight non-asthmatic group (p=0.02, and the Glu27 allele was more frequently found in the overweight asthmatics group when compared to the normal weight non-asthmatic group (p=0.03. Conclusions: The association of Arg16 allele with the occurrence of asthma and of the Glu27 allele with overweight asthmatic adolescents evidenced the contribution of the β2-adrenergic receptor gene to the development of obesity and asthma.

    Eosinophils play an important role in the pathogenesis of asthma and can be activated by extracellular nucleotides released following cell damage or inflammation. For example, increased ATP concentrations were reported in bronchoalveolar lavage fluids of asthmatic patients. Although eosinophils are known to express several subtypes of P2 receptors for extracellular nucleotides, their function and contribution to asthma remain unclear. In this article, we show that transcripts for P2X1, P2X4, and P2X5 receptors were expressed in healthy and asthmatic eosinophils. The P2X receptor agonist α,β-methylene ATP (α,β-meATP; 10 μM) evoked rapidly activating and desensitizing inward currents (peak 18 ± 3 pA/pF at -60 mV) in healthy eosinophils, typical of P2X1 homomeric receptors, which were abolished by the selective P2X1 antagonist NF449 (1 μM) (3 ± 2 pA/pF). α,β-meATP-evoked currents were smaller in eosinophils from asthmatic patients (8 ± 2 versus 27 ± 5 pA/pF for healthy) but were enhanced following treatment with a high concentration of the nucleotidase apyrase (17 ± 5 pA/pF for 10 IU/ml and 11 ± 3 pA/pF for 0.32 IU/ml), indicating that the channels are partially desensitized by extracellular nucleotides. α,β-meATP (10 μM) increased the expression of CD11b activated form in eosinophils from healthy, but not asthmatic, donors (143 ± 21% and 108 ± 11% of control response, respectively). Furthermore, α,β-meATP increased healthy (18 ± 2% compared with control 10 ± 1%) but not asthmatic (13 ± 1% versus 10 ± 0% for control) eosinophil adhesion. Healthy human eosinophils express functional P2X1 receptors whose activation leads to eosinophil αMβ2 integrin-dependent adhesion. P2X1 responses are constitutively reduced in asthmatic compared with healthy eosinophils, probably as the result of an increase in extracellular nucleotide concentration.

    Full Text Available Asthma is the most common chronic respiratory disease of children in the world. Serial studies in the world have showed an increased prevalence of bronchial asthma. In this study, the children younger than 12 years old referred to Jahrom hospital and clinic due to asthma were selected. We issued 100 questionnaires, according to International Study of Asthma and Allergies in Childhood (ISAAC criteria and were completed by the physicians. The ratio of male to female was 1 to 9. The patients who were under the age of 4, 3 and 1 year were 82%, 60% and 15% respectively. Passive smoking was present in 56% of the patients, and 22% had pets at home like cat, dog or bird. Home dampness was present in 33%. Ninety percent of patients had used breast feeding during the first year of life. Seventy percent of patients had family history of asthma. Food allergy was present and could trigger asthma in 15%. The result of ISSAC questionnaire showed that during the last year wheezing was present in 10%, 6% had 1-3 attacks and 4% had 4-12 attacks. Sleep disturbance by wheezing had occurred in 5% but cough in 16%. Thirteen percent of patients had wheezing after exercise. In Jahrom town the climate is warm and dry. In this town asthma in children is more common among the children who are younger than 4 years old. The risk factor like smoking at home, pets and home dampness should be eliminated from their environment.

    Full Text Available [b]introduction and objective[/b]. Numerous epidemiologic studies have reported increased risk of allergic rhinitis and asthma in relation to ‘western life-style’, which represents diversity of factors. We hypothesized that residential proximity to major roadways, reflecting an exposure to traffic-related air pollution, is associated with prevalence of allergic respiratory symptoms in children. [b]materials and methods[/b]. A total of 8290 individuals of two age groups: 16 year olds and 7 year olds from Krakow, Poland were included. We used the Polish version of the International Study of Asthma and Allergy in Childhood supplemented with a question concerning the distance between a responder’s house and a high traffic density road: below 200 m, from 200–500 m, or more than 500 m. [b]results[/b]. Children and adolescents with a residential proximity closer to a major roadway had more frequent asthma-related symptoms in the last 12 months and at any time in the past. Consistent with the increased frequency of asthmatic symptoms, responders residing within 200 meters complained more often of sneezing, runny or blocked nose accompanied by itchy-watery eyes and hay fever in comparison to responders who resided 200–500 meters from a major roadway. The lowest rate of nasal symptoms was observed in residents living in the distance to major roads (> 500 meters. The rate of positive answers decreased in a distant-dependent manner. [b]conclusions[/b]. Our findings suggest an important spatial relationship between the distance from a major roadway and the evaluated respiratory symptoms. The results emphasize the need for more comprehensive air quality policies within urban areas with increased motor vehicle density.

    The need to teach professionalism during residency has been affirmed by the Accreditation Council for Graduate Medical Education, which will require documentation of education and evaluation of professionalism by 2007. Recently the American Academy of Pediatrics has proposed the following components of professionalism be taught and measured: honesty/integrity, reliability/responsibility, respect for others, compassion/empathy, self-improvement, self-awareness/knowledge of limits, communication/collaboration, and altruism/advocacy. The authors describe a curriculum for introducing the above principles of professionalism into a pediatrics residency that could serve as a model for other programs. The curriculum is taught at an annual five-day retreat for interns, with 11 mandatory sessions devoted to addressing key professionalism issues. The authors also explain how the retreat is evaluated and how the retreat's topics are revisited during the residency, and discuss general issues of teaching and evaluating professionalism.

    Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity reaction due to a fungus, Aspergillus fumigatus. It is typically seen in patients with long-standing asthma. Our patient was a non-asthmatic 18 years old male who presented with chronic cough for 2 years. Peripheral blood eosinophilia and elevated scrum IgE were observed. His x-ray chest revealed v-shaped opacity in the left upper lobe close to the hilum. High resolution computed tomographic scan of the chest revealed multiple dilated bronchi filled with mucous (bronchoceles) and central bronchiectasis (CB) involving main segmental bronchi. Central bronchiectasis (CB) was typical of ABPA but bronchocele formation was a rare manifestation of the disease. The patient was managed with oral prednisolone and was relieved of his symptoms. Occurrence of ABPA in non-asthmatics is very rare and deserves reporting.

    Many orthopedic residents accrue considerable debt by residency graduation. These debts for graduating medical students continue to increase due to the yearly increase of medical school tuition. The purpose of this study was to examine the causes of financial debt, as well the effects of debt on orthopedic residents.Orthopedic residents from postgraduate years 1 to 5 (N=27) completed an anonymous, optional financial survey. The survey asked questions regarding the characteristics of the residents' debt and their concern caused by their debt. All residents from our institute (N=27) voluntarily participated in the survey. The residents consisted of 4 (15%) women and 23 (85%) men, with 14 (56%) single residents and 12 (44%) married residents. No statistically significant difference existed in total debt >$100,000 between single and married residents or men and women. Forty-eight percent (n=13) of the residents had medical educational debt >$100,000, whereas 45% (n=12) had total debt >$200,000. Residents with total debt >$100,000 were concerned about their debt, whereas 1 of 4 residents with orthopedic residents financially and may cause stress and hinder their medical training. Appropriate measures should be taken to help residents properly manage their debt and to provide supplemental assistance with their financial struggles.

  11. Eicosanoid Mediators in the Airway Inflammation of Asthmatic Patients: What is New?

    Science.gov (United States)

    Sanak, Marek

    2016-11-01

    Lipid mediators contribute to inflammation providing both pro-inflammatory signals and terminating the inflammatory process by activation of macrophages. Among the most significant biologically lipid mediators, these are produced by free-radical or enzymatic oxygenation of arachidonic acid named "eicosanoids". There were some novel eicosanoids identified within the last decade, and many of them are measurable in clinical samples by affordable chromatography-mass spectrometry equipment or sensitive immunoassays. In this review, we present some recent advances in understanding of the signaling by eicosanoid mediators during asthmatic airway inflammation. Eicosanoid profiling in the exhaled breath condensate, induced sputum, or their metabolites measurements in urine is complementary to the cellular phenotyping of asthmatic inflammation. Special attention is paid to aspirin-exacerbated respiratory disease, a phenotype of asthma manifested by the most profound changes in the profile of eicosanoids produced. A hallmark of this type of asthma with hypersensitivity to non-steroid anti-inflammatory drugs (NSAIDs) is to increase biosynthesis of cysteinyl leukotrienes on the systemic level. It depends on transcellular biosynthesis of leukotriene C₄ by platelets that adhere to granulocytes releasing leukotriene A₄. However, other abnormalities are also reported in this type of asthma as a resistance to anti-inflammatory activity of prostaglandin E₂ or a robust eosinophil interferon-γ response resulting in cysteinyl leukotrienes production. A novel mechanism is also discussed in which an isoprostane structurally related to prostaglandin E₂ is released into exhaled breath condensate during a provoked asthmatic attack. However, it is concluded that any single eicosanoid or even their complex profile can hardly provide a thorough explanation for the mechanism of asthmatic inflammation.

    Aspiration of acid to the airway causes airway inflammation, and acid stress to the airway caused by gastroesophageal reflux disease (GERD) has been known as a potential mechanism of deteriorated asthma symptoms. However, the efficacy of the acid suppressive drugs, H(2)-receptor blockers (H(2) blocker) and proton pump inhibitors, on asthma symptoms and pulmonary functions remains controversial. We therefore designed the randomized prospective study to determine the efficacy of an H(2) blocker (roxatidine, 150 mg/day) and a proton pump inhibitor (lansoprazole, 30 mg/day) on asthma symptoms of 30 asthmatic patients with GERD. These patients were divided in the two groups (15 patients for each group) and treated with either roxatidine or lansoprazole. The diagnosis of GERD was established by the method of Los Angeles classification including mucosal minimum change of Grade M and questionnaire for the diagnosis of reflux disease (QUEST) score. The efficacy of acid suppressive drugs was evaluated by peak expiratory flow (PEF), asthma control questionnaire (ACQ) that evaluates the improvement of asthma symptoms, and forced expiratory volume in 1 second (FEV(1.0)). Lansoprazole, but not roxatidine, significantly improved PEF and ACQ scores (p < 0.05) with the improved QUEST scores. However, these acid suppressive drugs did not change the pulmonary function of FEV(1.0) in asthmatic patients. In conclusion, treatment with a proton pump inhibitor, lansoprazole, appears to be useful in improvement of asthma symptoms in asthmatic patients with GERD.

    The cornerstone of asthma management is achieving adequate symptom control and patient education. We studied in our local population of asthmatic patients how well their symptoms were controlled with currently prescribed treatment and their insight into the disease and its management. Over a 6-month period, 93 asthmatics recruited from two local government health clinics and a state hospital were interviewed using a standard questionnaire. Patients were classified into 4 groups based on the treatment they were on according to Global Initiative for Asthma (GINA) treatment guidelines. The number of patients in Step 1 (rescue medication alone), Step 2 (1 controller medication), Step 3 (2 controller medications) and Step 4 (at least 3 controller medications) were 8, 39, 34 and 12, respectively. Except for day symptoms in Step 1 group, fewer than 50% achieved minimum day or night symptoms and no restriction of daily activities. Questions on patient insight were only available for 50 patients. Weather change (74%), air pollution (66%) and physical stress (46%) were the three highest ranked common asthma triggers. More than half correctly recognized the important symptoms of a serious asthma attack but fewer than 15% were familiar with the peak flow meter and its use or with the asthma self-management plan. Most patients perceived that their treatment had helped reduce disease severity and exacerbations. We conclude that symptom control and some aspect of patient education are still lacking in our local asthmatics.

During acute exacerbation, superoxide anion generation was higher in asthmatics than in eleven normal subjects (39.2 ± 14.1 vs. 25.2 ± 7.3 nmol, p 20% after GCS treatment (from 131 ± 18 to 117 ± 21 μm, p = 0.005. Chemokinesis sicantly decreased in all subjects, and the changes significantly correlated with an arbitrary score of the total administered dose of GCS (r = 0.57, p < 0.05. These data suggest that neutrophil activation plays a minor role in asthma, and that treatment with GCS is not able to modify most functions of peripheral neutrophils in asthmatic subjects; chemotaxis seems to be related only to the severity of the asthma and it could reflect the improvement of the disease.

    Full Text Available Introduction: Ramadan is the 9th  Islamic lunar month during which Muslims avoid eating and drinking from sunrise to sunset.  The effect of Ramadan intermittent fasting on asthma control is controversial.  The aim of this study was to investigate the effects of Ramadan fasting on the spirometric variables and clinical symptoms on well-controlled asthmatic patients during Ramadan. Material and Methods: a cohort study was conducted in Mashhad, Khorasan Razavi, Iran. Twenty-nine (19 females and 10 males well-controlled asthmatic patients aged 47 (12 years completed the study.  The average duration of fasting was 26.5 days. Assessment of spirometric variables (daily peak expiratory flow, peak expiratory flow variability, peak expiratory flow home monitoring as well as asthma clinical symptoms including dyspnea, cough, wheezing, and chest tightness were carried out. Results: No significant changes in clinical symptoms were reported in asthmatic patients at the end of Ramadan fasting.  Among spirometric variables, only peak expiratory flow improved after Ramadan (p

    Epidemiologic studies support an association between elevated levels of sulfates and increased symptoms in asthmatics. To determine if these pollutants produce airway responses, 17 asthmatics inhaled the following sulfates: sodium bisulfate, ammonium sulfate, ammonium bisulfate (NH4HSO4), or sulfuric acid (H2SO4) aerosols with an aerodynamic diameter of 0.80 micron at concentrations of 100 micrograms/m3, 450 micrograms/m3, and 1,000 micrograms/m3. A sodium chloride (NaCl) aerosol of similar characteristics, administered by double-blind randomization, served as a control. Subjects breathed these aerosols for a 16-minute period via a mouthpiece. Deposition studies showed 54 to 65% retention of the inhaled aerosols. At the 1,000 micrograms/m3 concentration, the Threshold Limit Value for occupational exposure, H2SO4 and NH4HSO4 inhalation produced significant reductions in specific airway conductance (SGaw) (p less than 0.05) and forced expiratory volume in one second (p less than 0.01) compared with NaCl or pre-exposure values. At the 450 micrograms/m3 concentration, only H2SO4 inhalation produced a significant reduction in SGaw (p less than 0.01). At 100 micrograms/m3, a level 3 to 5 times greater than peak urban levels, no significant change in airway function occurred after any sulfate exposure. These data indicate that asthmatics demonstrate bronchoconstriction after brief exposure to common acidic sulfate pollutants.

    We have studied 175 consecutive asthmatic patients presenting with: 1) a reversible airflow obstruction, demonstrated by an increase in the forced expiratory volume in 1 second (FEV1) or in the forced vital capacity (FVC) by at least 12% along with an absolute increase of 200 ml versus prebronchodilator values after inhalation of salbutamol; 2) FVC below the lower normal limit before administration of the bronchodilator; and 3) normal FVC or slow vital capacity after bronchodilator. Two different criteria for the lower normal limit of the FEV1/FVC ratio were used to determine whether prebronchodilator spirometric patterns could be considered obstructive or not. The use of the predicted FEV1/FVC ratio as the lower normal limit allowed correct identification of obstruction in 94.9% of the patients, whereas taking the estimated fifth percentile as the lower normal limit of the FEV1/FVC correctly identified obstruction in only 78.9% of the asthmatics. Our results suggest that the predicted FEV1/FVC ratio is an adequate estimate of the lower normal limit in asthmatic patients with reduced FVC in order to distinguish obstructive from nonobstructive patterns.

    Sometimes, antitussives can be a valid adjuvant to respiratory tract infections treatment. Although not always needed, this therapeutic support can be extremely useful in selected cases, and when patient is resident and monitored. In this line, the efficacy of a new peripheral antitussive, levodropropizine (Dompé farmaceutici, Milan), has been evaluated in 70 children inpatients of the Pediatric Department at san Paolo Hospital - Milan University - from September 1987 to May 1988. Thirty one male and 29 female children, aged 4 years and 6 months +/- 3 years and 5 months, suffering from various respiratory tract diseases were included in the study. Underlying diseases were represented by 21 acute bronchitis, 20 asthmatic attacks, 18 bronchopneumonia, 11 tracheitis, 6 acute episodes of chronic bronchitis, 2 hypoglottis laryngitis, 1 pertussis, 1 spontaneous pneumothorax. All parents gave their oral informed consent. The basic treatments were antibiotics in 44 patients associated or not with beta 2 agonists (31), theophylline (15), corticosteroids via aerosol (9) or parenterally (3), immunomodulators (2). Treatment with levodropropizine in the oral drops formulation at 2 mg pro kg a day was continued for 5 days and withdrawn according to the clinical evolution. Cough was registered by means of appropriate record forms given to the parents as well as with 120' tape recording whenever possible, i.e. 60 minutes before and 60 minutes after drug administration, on day one and 2. At treatment end, parents and investigator gave an antitussive efficacy judgement. Tolerability was evaluated as per clinical evolution and laboratory parameters.

    Full Text Available Abstract Background Asthma afflicts 6% to 8% of the United States population, and severe asthma represents approximately 10% of asthmatic patients. Several epidemiologic studies in the United States and Europe have linked Alternaria sensitivity to both persistence and severity of asthma. In order to begin to understand genetic risk factors underlying Alternaria sensitivity and asthma, in these studies we examined T cell responses to Alternaria antigens, HLA Class II restriction and HLA-DQ protection in children with severe asthma. Methods Sixty children with Alternaria-sensitive moderate-severe asthma were compared to 49 children with Alternaria-sensitive mild asthma. We examined HLA-DR and HLA-DQ frequencies in Alternaria-sensitive asthmatic by HLA typing. To determine ratios of Th1/Th2 Alternaria-specific T-cells, cultures were stimulated in media alone, Alternaria alternata extract and Alt a1. Sensitivity to IL-4 stimulation was measured by up-regulation of CD23 on B cells. Results Children with Alternaria-sensitive moderate-severe asthma trended to have increased sensitivities to Cladosporium (46% versus 35%, to Aspergillus (43% versus 28%, and significantly increased sensitivities to trees (78% versus 57% and to weeds (68% versus 48%. The IL-4RA ile75val polymorphism was significantly increased in Alternaria-sensitive moderate-severe asthmatics, 83% (0.627 allele frequency compared to Alternaria-sensitive mild asthmatics, 57% (0.388 allele frequency. This was associated with increased sensitivity to IL-4 stimulation measured by significantly increased IL-4 stimulated CD23 expression on CD19+ and CD86+CD19+ B cells of Alternaria-sensitive moderate-severe asthmatics. IL-5 and IL-13 synthesis was significantly increased in Alternaria-sensitive moderate-severe asthmatics compared to mild asthmatics to Alternaria extract and Alt a1 stimulation. The frequency of HLA-DQB1*03 allele was significantly decreased in Alternaria-sensitive moderate

    Full Text Available Resident participation in international health electives (IHEs has been shown to be beneficial, yet not all residents have the opportunity to participate. We sought to determine whether participating in simulated global health cases, via the standardized Simulation Use for Global Away Rotations (SUGAR curriculum, was useful for all pediatric residents, not merely those planning to go on an IHE. Pediatric residents in our program took part in 2 SUGAR cases and provided feedback via an online survey. Thirty-six of 40 residents participated (90%; 72% responded to the survey. Three of 10 residents not previously planning to work in resource-limited settings indicated participation in SUGAR made them more likely to do so. Nearly all residents (88% felt SUGAR should be part of the residency curriculum. All felt better prepared for working cross-culturally. While designed to prepare trainees for work in resource-limited settings, SUGAR may be beneficial for all residents.

    Full Text Available Abstract Introduction Air pollutant exposure has been associated with an increase in inflammatory markers and a decline in lung function in asthmatic children. Several studies suggest that dietary intake of fruits and vegetables might modify the adverse effect of air pollutants. Methods A total of 158 asthmatic children recruited at the Children's Hospital of Mexico and 50 non-asthmatic children were followed for 22 weeks. Pulmonary function was measured and nasal lavage collected and analyzed every 2 weeks. Dietary intake was evaluated using a 108-item food frequency questionnaire and a fruit and vegetable index (FVI and a Mediterranean diet index (MDI were constructed. The impact of these indices on lung function and interleukin-8 (IL-8 and their interaction with air pollutants were determined using mixed regression models with random intercept and random slope. Results FVI was inversely related to IL-8 levels in nasal lavage (p 1 (test for trend p 1 and FVC as was with MDI and ozone for FVC. No effect of diet was observed among healthy children. Conclusion Our results suggest that fruit and vegetable intake and close adherence to the Mediterranean diet have a beneficial effect on inflammatory response and lung function in asthmatic children living in Mexico City.

    Pediatric residency practices face the challenge of providing both behavioral health (BH) training for pediatricians and psychosocial care for children. The University of Rochester School of Medicine and Dentistry and Rochester General Hospital developed a joint training program and continuity clinic infrastructure in which pediatric residents and postdoctoral psychology fellows train and practice together. The integrated program provides children access to BH care in a primary care setting and gives trainees the opportunity to integrate collaborative BH care into their regular practice routines. During 1998-2008, 48 pediatric residents and 8 psychology fellows trained in this integrated clinical environment. The program's accomplishments include longevity, faculty and fiscal stability, sustained support from pediatric leadership and community payers, the development in residents and faculty of greater comfort in addressing BH problems and collaborating with BH specialists, and replication of the model in two other primary care settings. In addition to quantitative program outcomes data, the authors present a case example that illustrates how the integrated program works and achieves its goals. They propose that educating residents and psychology trainees side by side in collaborative BH care is clinically and educationally valuable and potentially applicable to other settings. A companion report published in this issue provides results from a study comparing the perceptions of pediatric residents whose primary care continuity clinic took place in this integrated setting with those of residents from the same pediatric residency who had their continuity clinic training in a nonintegrated setting.

    2004-01-01

    Summary: In order to investigate the effect of nuclear factor-κB (NF-κB) on airway remodeling in asthmatic rats, 18 Wistar rats were divided into three groups: asthmatic group; pyrrolidine dithiocarbamate (PDTC) group, in which rats were injected intraperitoneally with NF-κB specific inhibitor PDTC (100 mg/kg) before ovalbumin (OVA) challenge; control group. The NF-κB activity and the expression of inhibitory protein κBa (I-κBα) in airway were detected by electrophoretic mobility shift assay (EMSA), Western blot and immunohistochemistry respectively. The infiltration of inflammatory cells, the number of Goblet cells, the area of collagen and smooth muscle in airway were measured by means of image analysis system. The results showed that with the up-regulation of airway NF-κB activity in asthmatic group, the number of goblet cells (3.08 ±0.86/100μm basement membrane (BM)), the area of collagen (24.71 ± 4. 24 μm2/μm BM) and smooth muscle (13.81 ± 2.11 μm2/μm BM) in airway were significantly increased (P<0.05) as compared with control group (0.14±0. 05/100μm BM, 14.31 ±3.16 μm2/μm BM and 7.67±2.35 μm2/μm BM respectively) and PDTC group (0. 33±0. 14/100 μm BM, 18. 16±2.85 μm2/μm BM and 8.95±2.16 μm2/μm BM respectively). However, there was no significant difference between PDTC group and control group (P>0.05). It was concluded that the activity of NF-κB is increased in airway of asthmatic rats. Inhibition of NF-κB activation can attenuate constructional changes in asthma airway, suggesting NF-κB may contribute to asthmatic airway remodeling.

    Asthma, a chronic respiratory disease, can be aggravated by exposure to certain chemical irritants. The objectives were first to investigate the extent to which experimental observations on asthmatic subjects are taken into consideration in connection with the registration process under the EU REACH regulation, and second, to determine whether asthmatics are provided adequate protection by the derived no-effect levels (DNELs) for acute inhalation exposure. We identified substances for which experimental data on the pulmonary functions of asthmatics exposed to chemicals under controlled conditions are available. The effect concentrations were then compared with DNELs and other guideline and limit values. As of April 2015, only 2.6% of 269 classified irritants had available experimental data on asthmatics. Fourteen of the 22 identified substances with available data were fully registered under REACH and we retrieved 114 reliable studies related to these. Sixty-three of these studies, involving nine of the 14 substances, were cited by the REACH registrants. However, only 17 of the 114 studies, involving four substances, were regarded as key studies. Furthermore, many of the DNELs for acute inhalation were higher than estimated effect levels for asthmatics, i.e., lowest observed adverse effect concentrations or no-observed adverse effect concentrations, indicating low or no safety margin. We conclude that REACH registrants tend to disregard findings on asthmatics when deriving these DNELs. In addition, we found examples of DNELs, particularly among those derived for workers, which likely do not provide adequate protection for asthmatics.

    2013-11-01

    Certified nurses' assistants (CNAs) employed by a rural nursing home in Northeast Arkansas described their perceptions of resident-to-resident violence in order to provide insight on factors, including unmet needs, that may trigger the phenomenon. Semistructured interviews were conducted with 11 CNAs. Data were analyzed using content analysis and constant comparison. Two categories of triggers emerged from the data-active and passive. Active triggers involved the actions of other residents that were intrusive in nature, such as wandering into a residents' personal space, taking a resident's belongings, and so forth. Passive triggers did not involve the actions of residents but related to the internal and external environment of the residents. Examples were factors such as boredom, competition for attention and communication difficulties. Results indicate that there are factors, including unmet needs within the nursing home environment that may be identified and altered to prevent violence between residents.

    Residents have the rights and responsibilities of both students and employees. Dismissal of a resident from a training program is traumatic and has lasting repercussions for the program director, the faculty, the dismissed resident, and the residency. A review of English language literature was performed using PUBMED and OVID databases, using the search terms, resident dismissal, resident termination, student dismissal, student and resident evaluation, legal aspects of education, and remediation. The references of each publication were also reviewed to identify additional appropriate citations. If the Just Cause threshold has been met, educators have the absolute discretion to evaluate academic and clinical performance. Legal opinion has stated that it is not necessary to wait until a patient is harmed to dismiss a resident. Evaluations should be standard and robust. Negative evaluations are not defamatory as the resident gave consent to be evaluated. Provided departmental and institutional polices have been followed, a resident can be dismissed without a formal hearing. Residencies are entitled to modify academic requirements and dismissal is not considered a breach of contract. Although there is anxiety regarding resident dismissal, the courts have uniformly supported faculty having this role. When indicated, failure to dismiss a resident also places the program director and the faculty at risk for educational malpractice.

    Estimating the prevalence of asthma is an epidemiologic challenge, particularly in rural areas of lesser-developed countries characterized by low literacy and poor access to health care. To avoid under or over reporting of symptoms, questionnaires must use terminology familiar to participants and that accurately describes the triad of cough, wheeze and breathlessness characteristic of asthma. In preparation for a large longitudinal cohort study entitled Chronic Respiratory Effects of Early Childhood Exposure to Respirable Particulate Matter (CRECER) that will examine the effects of variable early lifetime woodsmoke exposure on the respiratory health of Mam-speaking children residing in communities in the western highlands of Guatemala, we conducted individual interviews (n=18) and five focus groups (n=46) with indigenous women from 17 of these communities to elicit and define local Mam and Spanish terms for common respiratory symptoms used to describe their own and their children's respiratory symptoms. Focus group participants were also shown an International Study of Asthma and Allergies in Childhood (ISAAC) video of wheezing children and adults. We developed a conceptual framework that can be used as an efficient model for future studies investigating health and/or disease terminology in isolated communities, an integral step in the development of standardized questionnaires. Among this Mam-speaking population, wheeze was best described as nxwisen or ntzarrin, "breathing sounds that are heard in the neck but come from the chest." The variation in understanding of terms between women with and without children with a history of wheeze (such that for those without wheezing children some terms were virtually unrecognized), has important implications for large-scale population surveys within countries and comparative surveys such as ISAAC. It is important to use linguistically and culturally appropriate terminology to describe wheeze in prevalence studies of

    Full Text Available A higher proportion of children with asthma are overweight and obese compared to children without asthma; however, it is unknown whether asthmatic children are at increased risk of weight gain due to modifiable lifestyle factors. Thus, the aim of this cross-sectional study was to compare weight-gain risk factors (sleep, appetite, diet, activity in an opportunistic sample of children with and without asthma. Non-obese children with (n = 17; age 10.7 (2.4 years and without asthma (n = 17; age 10.8 (2.3 years, referred for overnight polysomnography, underwent measurement of lung function, plasma appetite hormones, dietary intake and food cravings, activity, and daytime sleepiness. Sleep latency (56.6 (25.5 vs. 40.9 (16.9 min, p = 0.042 and plasma triglycerides (1.0 (0.8, 1.2 vs. 0.7 (0.7, 0.8 mmol/L, p = 0.013 were significantly greater in asthmatic versus non-asthmatic children. No group difference was observed in appetite hormones, dietary intake, or activity levels (p > 0.05. Sleep duration paralleled overall diet quality (r = 0.36, p = 0.04, whilst daytime sleepiness paralleled plasma lipids (r = 0.61, p =0.001 and sedentary time (r = 0.39, p = 0.02. Disturbances in sleep quality and plasma triglycerides were evident in non-obese asthmatic children referred for polysomnography, versus non-asthmatic children. Observed associations between diet quality, sedentary behavior, and metabolic and sleep-related outcomes warrant further investigation, particularly the long-term health implications.

A residency club was started in 1982 to increase UOP students' interest in residency training and to provide them with relevant information. Some students needed to be convinced that residencies were primarily educational rather than staffing experiences. Students were made aware of pharmacists' practice in specialty areas, for which residency training is needed, and were taught how to prepare themselves for selection for residencies. The club was formed to encourage mutual support among the students, which would be less likely to occur if residencies were promoted only through work with individual students. Club meetings provide information about available residencies, the application process, and the value of residency training to a career in pharmacy. Students are taught how to prepare curricula vitae, how to interview, and how to select programs to which to apply. Applications for residencies increased. Although the rate of acceptance was low at first, it was expected to increase as more UOP students demonstrated their interest in and qualification for residency training. The promotion of residencies as part of a balanced career planning and placement program for pharmacy students is encouraged.

    Our goal in this study was to examine Accreditation Council for Graduate Medical Education case logs for Stanford anesthesia residents graduating in 2013 (25 residents) and 2014 (26 residents). The resident with the fewest recorded patients in 2013 had 43% the number of patients compared with the resident with the most patients, and in 2014, this equaled 48%. There were residents who had 75% more than the class average number of cases for several of the 12 case types and 3 procedure types required by the Accreditation Council for Graduate Medical Education. Also, there were residents with fewer than half as many for some of the required cases or procedure types. Some of the variability may have been because of the hazards of self-reporting.

    Full Text Available Introduction. It has been suggested that asthmatic patients may have a higher risk for oral diseases, both as a result of the medical condition and effects of medications. Objective. The aim of the study was to determine the oral health status of children with asthma and to evaluate the oral health parameters according to the medications and severity of the disease. Methods. The study group consisted of 158 children with asthma and 100 healthy control subjects aged 2-18 years. The diagnosis of dental caries was performed using the Decayed, Missing, and Filled Teeth (DMFT/dmft criteria. The oral hygiene, periodontal status and gingival health were assessed with the Simplified Oral Hygiene Index (Greene-Vermillion, Community Periodontal Index of Treatment Needs and Gingival Index (Löe-Silness, respectively. Results. Thirty (19% patients with asthma and 43 (43% healthy children were caries-free (p<0.001. There were no significant differences between asthmatic and control children in caries experience (for children with asthma mean DMFT=2.1±1.8, mean dmft=4.2±3.3; for healthy children mean DMFT=2.5±0.9, mean dmft=5.2±1.3. Level of asthma control did not have influence on dental health, while dose of inhaled corticosteroid had impact on primary dentition. Periodontal status and gingival health did not differ between asthmatic and control children. However, children with asthma had poorer oral hygiene (p<0.001. Conclusion. Results of the study do not show a relationship between asthma and oral diseases. However, further improvement could be made in educating children and parents on the importance of good oral hygiene and prevention of oral diseases.

    The authors review trends in the size of the resident foreign population in Spain over time since the 1940s. A continuing growth over time, with temporal fluctuations, is noted, with a rapid rise in immigration in the 1980s, leading to new legislation designed to control immigration in 1985-1986 and 1991. The authors note that Europeans, particularly from countries of the European Union, make up a large percentage of the foreign population, but that the number of immigrants from developing countries has increased significantly in the last 10 years.

    Full Text Available Abstract Background Sex hormones may play an important role in observed gender differences in asthma incidence and severity, as well as in the observed changes in asthma symptoms during times of hormonal fluctuation (i.e.; premenstrual, pregnancy, etc.. This pilot study sought to demonstrate the feasibility of data collection methods to investigate the effects of sex hormones on lung function in women. Findings A cohort of 13 women (6 with and 7 without prior asthma diagnoses who were having menstrual periods and were not taking hormones collected urine samples daily for measurement of estrogen (estrone E1C and progesterone (Pregnanediol-glucuronide PDG metabolites over the course of a menstrual segment (bleeding episode plus the following bleeding-free interval. Hormones were used to estimate menstrual segment phase (follicular versus luteal based on a published algorithm. Daily bleeding and FEV1 measurements were recorded and percent predicted FEV1 was calculated. Percent predicted FEV1 decreased over the course of the follicular but not the luteal phase. More specifically, among women without a prior asthma diagnosis, the E1C/PDG ratio and E1C and PDG were individually associated with FEV1 in the follicular phase. No associations were found between hormones and percent predicted FEV1 in the luteal phase or among asthmatic women. E1C was associated with FEV1 in the five days before bleeding onset only among non-asthmatic women. Discussion A study of contiguous daily hormones and symptoms over menstrual segments from a large group of women with and without asthma is needed to better determine within-woman cyclicity of the observed patterns.

    Objective Exposure of DNA to sulfur mustard gas may increase the inheritance of asthma in chemical warfare victims' (CWV) offspring. The objective of this study was to determine the prevalence of asthma in children of CWV and compare it to asthmatic children in the general population. Methods Four hundred and nine children from 130 CWV fathers and 440 children from 145 asthmatic parents from two cities in Iran participated in this study. The prevalence of asthma was determined by standard questionnaire released for epidemiological survey of asthma in children and compared between two groups. Findings The prevalence of asthma in the CWV group was 15%; this was not significantly different from the control group (12.5%). The children of the CWV group reported a significantly greater incidence of wheezing (1.2±3.1 attacks) per year, but the control group reported more severe attacks leading to speech difficulties (3%) and coughing (7%). Regression analysis showed that with increasing family size in the control group, the number of subjects suffering from asthmatic symptoms decreases significantly (r=0.86, P=0.001). Conclusion Chemical agents may increase the prevalence of asthma in the offspring of CWV. PMID:23056804

    Full Text Available Objective: During the last decades, an increase in the prevalence of asthma and other allergic diseases has been recorded, together with modifications in the living environment and consequent changes in the quality of indoor air. Indoor environment is favorable to the proliferation of allergens such as: house dust mites, fungal spores and cockroaches. The primary action to be undertaken for an effective eradication of infectious agents constitutes in modifying the house environmental conditions, which make it favorable to infestations. Ozone can play a sanitize role, but at the same time it can cause inflammation, especially in the lung. The aim of this study was to verify the role and safety of ozone in the sanitation of the bedroom of a subject suffering from asthma. Methods: A daily ozone treatment was carried during a 14-day time period in the bedroom of an asthmatic patient. Aerobiological sampling in indoor air, microbiological sampling and detection of ATP bioluminescence on the surface were performed before and after treatment at the first day, as well as after treatment at the 7th and 14th day of the study. An aerobiological measurement was also performed outdoor of the patient and #8217;s bedroom only for the first day. Results: Our analysis confirms that low ozone levels induced a marked reduction of indoor air microbiological pollution without adverse effects on lung functionality of the asthmatic patient we considered. Conclusion: Our observations warrant further investigation on the role that ozone-based sterilization might have in controlling asthmatic symptoms. [J Exp Integr Med 2015; 5(3.000: 128-136

    AIM: To study the effect of combined omeprazole(Ome) and domperidone(Dom) therapy on asthma symptoms and pulmonary function in asthmatics with gastroesoph ageal reflux.METHODS: We selected 198 asthmatics with gastro esophageal reflux diagnosed by 24-h esophageal pH moni toring to receive Ome 20 mg twice daily and Dom 10 mg three times daily or placebo for 16 wk (1:1 double-blind randomization). Spirometry was done at baseline and af ter 16 wk of treatment. The primary outcome measures were: mean daily daytime and nighttime asthma symp tom scores. Mean daily reflux symptom scores, albuterol use as rescue medication (number of puffs), daytime and nighttime peak expiratory flow rate (PEFR), postbroncho dilator forced expiratory volume in 1 second (FEV1) and postbronchodilator forced vital capacity (FVC) were sec ondary outcome measures.RESULTS: Comparison of mean change from baseline between antireflux therapy and placebo groups revealed significant reduction in daytime asthma symptom score (17.4% vs 8.9 %), nighttime asthma symptom score (19.6% vs 5.4%), reflux symptom score (8.7% vs 1.6%) and rescue medication use (23.2% vs 3.1%) after antire flux therapy compared to mean change in placebo group (P < 0.001). There was significant improvement in morn ing PEFR (7.9% vs 0.2%), evening PEFR (9.8% vs 0.5%), FEV1 (11.1% vs 3.78%) and FVC (9.3% vs 1.52%) in the antireflux therapy group compared to placebo on comparing the mean change from baseline after 16 wk (P < 0.01).CONCLUSION: Combined therapy with Ome and Dom in adult asthmatics with gastroesophageal reflux may be beneficial by reducing asthma symptoms, rescuing medi cation use, and improving pulmonary function.

    Objective: To study the phytochemistry, anti-asthmatic and antioxidant activities of the aqueous leaf extract of Anchomanes difformis(Blume) Engl.(A. difformis) and to verify claims of use in folk medicine.Methods: For anti-asthmatic activity, male and female guinea pigs with average body weight of(451.4 ± 118.1) g were divided into six groups of six animals each. Group 1served as control(distilled water); Group 2 was administered with salbutamol(reference drug) only; Group 3 served as ovalbumin sensitized group, Group 4, 5 and 6 were treated with A. difformis extract at doses of 100, 200 and 400 mg/kg, respectively. Described methods were used to test fluid viscosity, fluid volume and quantitative phytochemistry analysis. Absorbance was read using a UV–Vis spectrophotometer and results computed in percentage. Total antioxidant assays [2, 2-diphenyl-1-picrylhydrazyl(DPPH) and lipid peroxidation assay], were carried out using reported procedures.Results: The anti-asthmatic evaluation showed that protection from asthma of the animals in Group 6(400 mg/kg, 32.7%) were similar to that in Group 2(salbutamol, 33.0%).Excised trachea was free of mucus secretion in Group 5(200 mg/kg) as was observed in the control group. Fluid volume increase in Groups 3 and 6 indicated mucus secretion.DPPH radical scavenging activity of extract was effective as ascorbic acid which served as standard at 20 mg/m L. But, the extract elicited low lipid peroxidation activity compared with the reference(tocopherol) at concentrations tested.Conclusions: A. difformis aqueous leaf extract is safe and possesses positive antiasthmatic and antioxidant activities as claimed by traditional herbal practitioners in Delta State.

    Full Text Available Gastroesophageal reflux (GER is common in asthma patients and can contribute to sleep disruption. The aim of the present study was to determine the time-related distribution of GER events together with their impact on sleep in asthmatic subjects with GER disease symptoms. The inclusion criteria were: 18-65 years, controlled moderate to severe asthma and GER-compatible clinical evidence. The exclusion criteria were: chronic obstructive lung disease, smoking, infections of the upper airways, use of oral corticosteroids, other co-morbidities, pregnancy, sleep-related disorders, night-time shift work, and the use of substances with impact on sleep. Asthmatic patients with nocturnal symptoms were excluded. All-night polysomnography and esophageal pH monitoring were recorded simultaneously. Of the 147 subjects selected, 31 patients and 31 controls were included. Seventeen patients were classified as DeMeester positive and 14 as DeMeester negative. Both groups displayed similar outcomes when general variables were considered. Sleep stage modification one minute prior to GER was observed in the DeMeester-positive group. Awakening was the most frequent occurrence at GER onset and during the 1-min period preceding 38% of the nocturnal GER. Sleep stage 2 was also prevalent and preceded 36% of GER events. In the DeMeester-negative group, awakening was the most frequent response before and during GER. Modifications in sleep stages, arousals or awakenings were associated with 75% of the total GER events analyzed during the period of one minute before and after the fall of esophageal pH below 4 in the DeMeester-positive group. These data provide evidence that sleep modifications precede the GER events in asthmatic patients.

    Inflammatory monocyte and tissue macrophages influence the initiation, progression, and resolution of type 2 immune responses, and alveolar macrophages are the most prevalent immune-effector cells in the lung. While we were characterizing the M1- or M2-like macrophages in type 2 allergic inflammation, we discovered that FoxO1 is highly expressed in alternatively activated macrophages. Although several studies have been focused on the fundamental role of FoxOs in hematopoietic and immune cells, the exact role that FoxO1 plays in allergic asthmatic inflammation in activated macrophages has not been investigated. Growing evidences indicate that FoxO1 acts as an upstream regulator of IRF4 and could have a role in a specific inflammatory phenotype of macrophages. Therefore, we hypothesized that IRF4 expression regulated by FoxO1 in alveolar macrophages is required for established type 2 immune mediates allergic lung inflammation. Our data indicate that targeted deletion of FoxO1 using FoxO1-selective inhibitor AS1842856 and genetic ablation of FoxO1 in macrophages significantly decreases IRF4 and various M2 macrophage-associated genes, suggesting a mechanism that involves FoxO1-IRF4 signaling in alveolar macrophages that works to polarize macrophages toward established type 2 immune responses. In response to the challenge of DRA (dust mite, ragweed, and Aspergillus) allergens, macrophage specific FoxO1 overexpression is associated with an accentuation of asthmatic lung inflammation, whereas pharmacologic inhibition of FoxO1 by AS1842856 attenuates the development of asthmatic lung inflammation. Thus, our study identifies a role for FoxO1-IRF4 signaling in the development of alternatively activated alveolar macrophages that contribute to type 2 allergic airway inflammation.

    Phloretin (PT), isolated from the apple tree, was previously demonstrated to have antioxidative and anti-inflammatory effects in macrophages and anti-adiposity effects in adipocytes. Inflammatory immune cells generate high levels of reactive oxygen species (ROS) for stimulated severe airway hyperresponsiveness (AHR) and airway inflammation. In this study, we investigated whether PT could reduce oxidative stress, airway inflammation, and eosinophil infiltration in asthmatic mice, and ameliorate oxidative and inflammatory responses in tracheal epithelial cells. BALB/c mice were sensitized with ovalbumin (OVA) to induce asthma symptoms. Mice were randomly assigned to the five experimental groups: normal controls; OVA-induced asthmatic mice; and OVA-induced mice injected intraperitoneally with one of the three PT doses (5, 10, or 20 mg/kg). In addition, we treated inflammatory human tracheal epithelial cells (BEAS-2B cells) with PT to assess oxidative responses and the levels of proinflammatory cytokines and chemokines. We found that PT significantly reduced goblet cell hyperplasia and eosinophil infiltration, which decreased AHR, inflammation, and oxidative responses in the lungs of OVA-sensitized mice. PT also decreased malondialdehyde levels in the lung and reduced Th2 cytokine production in bronchoalveolar lavage fluids. Furthermore, PT reduced ROS, proinflammatory cytokines, and eotaxin production in BEAS-2B cells. PT also suppressed monocyte cell adherence to inflammatory BEAS-2B cells. These findings suggested that PT alleviated pathological changes, inflammation, and oxidative stress by inhibiting Th2 cytokine production in asthmatic mice. PT showed therapeutic potential for ameliorating asthma symptoms in the future. PMID:28243240

    Antecedentes: las redes sociales se utilizan para el apoyo de los pacientes con asma; sin embargo, no se conocen las expectativas de los padres y los cuidadores de los pacientes con respecto al uso de estas redes. Objetivo: evaluar las expectativas de los padres y los cuidadores de niños asmáticos atendidos en el Programa de Prevención del Asma Infantil (PIPA, Uruguaiana, RS) con respecto al uso de las redes sociales. Material y método: estudio observacional, descriptivo, de corte transversal, en el que padres y cuidadores de niños tratados en el Programa de Prevención del Asma Infantil respondieron a un cuestionario escrito acerca del uso de las nuevas tecnologías y las diversas aplicaciones para mejorar la información acerca del asma. Resultados: participaron 210 padres o cuidadores (mediana de edad: 25 años; intervalo de edad: 18-42 años) de pacientes con edad promedio de 7.3 años (intervalo de edad: 2 a 18 años) y duración del asma de 4.7 años; 65% de los padres o cuidadores tuvo menos de ocho años de grado de escolaridad. La mayoría de ellos (72%) no tenía acceso a Internet a través de sus teléfonos y sólo 18% obtenía información activamente acerca del asma por Internet; 87% refirió su interés por recibir información a través de las redes sociales. Conclusión: los padres o cuidadores de niños atendidos en el Programa de Prevención del Asma Infantil expresaron gran interés en el uso de redes sociales, pero pocos las usan para controlar la enfermedad de los niños. Aunque las redes sociales proporcionan un gran beneficio para la salud, esta información debe ser vigilarse en relación con su fiabilidad y calidad. La privacidad de los usuarios (médicos y pacientes) debe ser preservada y debe facilitarse su acceso a Internet.

    Full Text Available Abstract Background Despite the development and dissemination of guidelines for the diagnosis and management of asthma, a gap remains between current recommendations and actual practice. Objectives To assess the physicians attitude towards asthma guidelines and their adherence to its recommendations. Methods Three hundred and fifty two clinicians (101 General practitioners, 131 pediatric specialists, 35 pediatric consultants and 85 doctors did not report the qualification engaged in direct childhood asthma care in Cairo, Egypt were subjected to a self-administered questionnaire with 35 questions of which most were multiple choices, aiming at assessment of three important aspects about the involved physicians; physician's knowledge, practice and attitude. 165 of the clinicians were working in governmental hospitals, 68 clinicians work in private clinics and 119 clinicians work in both. Results Agreement with asthma guidelines was present in 76.2% of the studied physicians, however those who not in agreement with the guidelines claimed that this was mainly due to patient factors, firstly the poor socioeconomic standard of the patient (18.1% and secondly due to poor patient compliance (16%. Poor knowledge was found in 28.5%, poor practice was found in 43.6% and poor attitude was found in 14.4% of the studied physicians. There was positive highly significant correlation between qualification and knowledge, (p Conclusion The attitude of the studied physicians revealed agreement of their majority with the guidelines, while the disagreement was mainly explained by the poor socioeconomic standard of the patients. The degree of poor practice is more marked than that of poor knowledge or poor attitude reflecting resources limitations and applications obstacles in the physician's practice.

    Nuclear imaging plays a critical role in asthma research but is limited in its readings of biology due to the short-lived signals of radio-isotopes. We employed hybrid fluorescence molecular tomography (FMT) and x-ray computed tomography (XCT) for the assessment of asthmatic inflammation based on resolving cathepsin activity and matrix metalloproteinase activity in dust mite, ragweed, and Aspergillus species-challenged mice. The reconstructed multimodal fluorescence distribution showed good correspondence with ex vivo cryosection images and histological images, confirming FMT-XCT as an interesting alternative for asthma research.

    Background The extracellular signal-regulated kinase (ERK) is widely expressed in mammal cells and involved in airway proliferation and remodeling in asthma. In this study, we intend to explore the role of ERK in the expression of the Th2 cytokine, interleukin 13 (IL-13) in lymphocytes in asthma.Methods Forty Sprague-Dawley rats were randomly divided into two groups: normal control and asthmatic groups. Peripheral blood lymphocytes were isolated and purified from the blood of each rat and divided into five groups: control, asthmatic lymphocytes, asthmatic cells stimulated with ERK activator epidermal growth factor (EGF), or with ERK inhibitor PD98059, or with EGF and PD98059 together. The expression of phosphorylated-ERK (p-ERK) was observed by immunocvtochemical staining, the expression of ERK mRNA was determined by reverse transcriptase-PCR, IL-13 protein in supernatants was measured by ELISA.Results (1) The ERK mRNA level and the percentage of cells with p-ERK in lymphocytes from asthmatic rats were significantly higher than those in normal controls, and were significantly increased by EGF administration. This effect of EGF was significantly inhibited by PD98059 pretreatment. (2) IL-13 protein in supematants of asthmatic lymphocytes was higher than that produced by normal control lymphocytes, and was significantly increased by EGF treatment. This EGF effect was partly blocked by PD98059 pretreatment. (3) There was a significant positive correlation between the percentage of cells with p-ERK in peripheral blood lymphocytes and IL-13 protein in supematants of lymphocytes from asthmatic rats.Conclusions In asthma the ERK expression and activation levels were increased, as was the protein level of IL-13. The ERK signaling pathway may be involved in the increased expression of the Th2 cytokine IL-13 in asthma.

    2013-02-01

    The American Academy of Pediatrics (AAP) is committed to the development of rational, equitable, and effective parental leave policies that are sensitive to the needs of pediatric residents, families, and developing infants and that enable parents to spend adequate and good-quality time with their young children. It is important for each residency program to have a policy for parental leave that is written, that is accessible to residents, and that clearly delineates program practices regarding parental leave. At a minimum, a parental leave policy for residents and fellows should conform legally with the Family Medical Leave Act as well as with respective state laws and should meet institutional requirements of the Accreditation Council for Graduate Medical Education for accredited programs. Policies should be well formulated and communicated in a culturally sensitive manner. The AAP advocates for extension of benefits consistent with the Family Medical Leave Act to all residents and interns beginning at the time that pediatric residency training begins. The AAP recommends that regardless of gender, residents who become parents should be guaranteed 6 to 8 weeks, at a minimum, of parental leave with pay after the infant's birth. In addition, in conformance with federal law, the resident should be allowed to extend the leave time when necessary by using paid vacation time or leave without pay. Coparenting, adopting, or fostering of a child should entitle the resident, regardless of gender, to the same amount of paid leave (6-8 weeks) as a person who takes maternity/paternity leave. Flexibility, creativity, and advanced planning are necessary to arrange schedules that optimize resident education and experience, cultivate equity in sharing workloads, and protect pregnant residents from overly strenuous work experiences at critical times of their pregnancies.

    Full Text Available ABSTRACT Background Asthma is difficult to diagnose in children and at times misdiagnosis of an infection can occur. However, little is known about the magnitude and patterns of antibiotic consumption in children with asthma relative to those without asthma. Methods Using population-based data, 128,872 children were identified with at least 6 years of follow-up. The adjusted rate-ratio (RR of antibiotics dispensed to asthmatic as compared to non-asthmatic children was determined. Results At age six, the RR of antibiotic consumption for asthmatics compared to non-asthmatics varied between, 1.66 to 2.32, depending on the year of asthma diagnosis. Of the 18,864 children with asthma at ages 2-8, 52% (n = 9,841 had antibiotics dispensed in the 6 months prior to their index date of asthma diagnosis. The RR of antibiotic consumption in the 1 month prior to asthma diagnosis compared to 5 months prior was 1.66 (95% CI 1.60-1.71. The RR was lower in males compared to females (1.58 vs 1.77, and lower in those who received antibiotics in the first year of life relative to those that did not (1.60 vs. 1.76. Conclusions There is higher antibiotic consumption in children with asthma compared to those without asthma. The pattern of antibiotic use suggests that diagnosis guidelines are difficult to follow in young children leading to misdiagnosis and over treatment with antibiotics.

    Blood concentration of endogenous beta-endorphines can change during the clinical evolution of chronic bronchopneumopathies. The authors assessed the beta-endorphine concentrations in the pulmonary arterial and systemic arterial blood in 8 asthmatic patients during a symptom-free period and after methacholine-induced bronchospasm. The beta-endorphine analysis was performed in duplicate dor each sample, by means of a RIA assay. There is not difference in the systemic arterial blood concentration of beta-endorphines between asthmatic patients and normal subjects. Furthermore, there is no change in the beta-endorphine blood concentration during the passage through the pulmonary tissue after methacoline-induced bronchospasm.

    Variability in children's allergic sensitization has been detected not only among different countries but also among cities within the same nation but yet different climatic areas. The aim of this study was to investigate the sensitization pattern of asthmatic children who lived in different altitude areas: the two largest Turkish cities, Istanbul (sea level) and Erzurum (high altitude). Five hundred and twelve asthmatic children (6-15 years old) from Istanbul (western Turkey, at sea level) and 609 from Erzurum (eastern Turkey, at an altitude of 1800 m) were included in the study. All participants underwent skin testing with common inhalant allergens, spirometry, total IgE level, and clinical examination. The positive sensitization ratio to aeroallergens in children with asthma living at sea level was statistically higher than that in children living in the high altitude group [ p = 0.001, OR (odds ratio) 4.9 (confidence interval (CI) 3.67-6.459)]. However, pollen sensitization in asthmatic children living in high altitudes was significantly higher than that in children living at sea level [ p = 0.00, OR 2.6 (CI 1.79-3.87)]. Children with asthma who live at high altitudes are characterized by higher pollen but lower mite sensitization rates than those living at sea level in Turkey. Different climatic conditions and altitudes may affect aeroallergen sensitization in children with asthma.

    Recently, we reported a reproducible model of asthma in guinea-pigs in vivo, which developed a late asthmatic response (LAR) as well as an early response. In this study, time-related changes in the occurrence of the LAR and leucocyte kinesis were assessed. Furthermore, the state of the activation of eosinophils that migrated into the lower airways was characterized in vitro. Guinea-pigs were alternately sensitized/challenged by inhalation with aerosolized ovalbumin adsorbed on aluminium hydroxide and ovalbumin alone, once every 2 weeks. At defined times before and after the fifth challenge, airway resistance was measured, blood was drawn and bronchoalveolar lavage (BAL) and nasal cavity lavage (NCL) were performed. Superoxide anion (.O2-) production of eosinophils was measured with cytochrome c. Occurrence of LAR and considerable increases in circulating eosinophils coincided with each other 5-7 h after the challenge. After 7 h, eosinophil infiltrations into bronchoalveolar spaces were observed. The capacity of eosinophils from the sensitized animals to produce .O2- was higher than those from the non-sensitized ones, when eosinophils were stimulated by platelet-activating factor. Although an increased number of eosinophils in the NCL fluid was observed, it was much less than that in the BAL fluid. Thus, it has been concluded that eosinophilia in the blood and the lung may participate in the occurrence of the late asthmatic response, which is thought to be preferentially evoked in the lower airways in guinea-pigs in vivo.

  5. Accumulating evidence for increased velocity of airway smooth muscle shortening in asthmatic airway hyperresponsiveness.

    It remains unclear whether airway smooth muscle (ASM) mechanics is altered in asthma. While efforts have originally focussed on contractile force, some evidence points to an increased velocity of shortening. A greater rate of airway renarrowing after a deep inspiration has been reported in asthmatics compared to controls, which could result from a shortening velocity increase. In addition, we have recently shown in rats that increased shortening velocity correlates with increased muscle shortening, without increasing muscle force. Nonetheless, establishing whether or not asthmatic ASM shortens faster than that of normal subjects remains problematic. Endobronchial biopsies provide excellent tissue samples because the patients are well characterized, but the size of the samples allows only cell level experiments. Whole human lungs from transplant programs suffer primarily from poor patient characterization, leading to high variability. ASM from several animal models of asthma has shown increased shortening velocity, but it is unclear whether this is representative of human asthma. Several candidates have been suggested as responsible for increased shortening velocity in asthma, such as alterations in contractile protein expression or changes in the contractile apparatus structure. There is no doubt that more remains to be learned about the role of shortening velocity in asthma.

    Full Text Available Background. Allergic diseases impair health-related quality of life (HR-QoL. However, the relationship between airway inflammation and HR-QoL in patients with asthma and rhinitis has not been fully investigated. We explored whether the inflammation of upper and lower airways is associated with HR-QoL. Methods. Twenty-two mild allergic asthmatics with concomitant rhinitis (10 males, 38 ± 17 years were recruited. The Rhinasthma was used to identify HR-QoL, and the Asthma Control Test (ACT was used to assess asthma control. Subjects underwent lung function and exhaled nitric oxide (eNO test, collection of exhaled breath condensate (EBC, and nasal wash. Results. The Rhinasthma Global Summary score (GS was 25 ± 11. No relationships were found between GS and markers of nasal allergic inflammation (% eosinophils: , ; ECP: , or bronchial inflammation (pH of the EBC: , ; bronchial NO: , ; alveolar NO: , . The mean ACT score was 18. When subjects were divided into controlled (ACT ≥ 20 and uncontrolled (ACT < 20, the alveolar NO significantly correlated with GS in uncontrolled asthmatics (, . Conclusions. Upper and lower airways inflammation appears unrelated to HR-QoL associated with respiratory symptoms. These preliminary findings suggest that, in uncontrolled asthma, peripheral airway inflammation could be responsible for impaired HR-QoL.

    Full Text Available Abstract Background Studies have shown that epinephrine release is impaired in patients with asthma. The pregnancy of female rats (dams with asthma promotes in their pups the differentiation of adrenal medulla chromaffin cells (AMCCs into sympathetic neurons, mediated by nerve growth factor, which leads to a reduction in epinephrine secretion. However, the relatedness between the alteration of AMCCs and increased asthma susceptibility in such offspring has not been established. Methods In this study, we observed the effects of allergization via ovalbumin on rat pups born of asthmatic dams. Results Compared to the offspring of untreated controls, bronchial hyperreactivity and airway inflammation were more severe in the pups from sensitized (asthmatic dams. In pups exposed to nerve growth factor (NGF in utero these effects were aggravated further, but the effects were blocked in pups whose dams had been treated with anti-NGF. Furthermore, alterations in AMCC phenotype corresponded to the degree of bronchial hyperreactivity and lung lesions of the different treatment groups. Such AMCC alterations included degranulation of chromaffin granules, reduction of epinephrine and phenylethanolamine-n-methyl transferase, and elevation of NGF and peripherin levels. Conclusions Our results present evidence that asthma during the pregnancy of rat dams promotes asthma susceptibility in their offspring, and that the transformation of AMCCs to neurons induced by NGF plays an important role in this process.

    Computational fluid dynamic simulations are performed to investigate flow characteristics and quantify particle deposition with normal and severe asthmatic lungs. Continuity and Navier-Stokes equations are solved with unstructured meshes and finite element method; a large eddy simulation model is adopted to capture turbulent and/or transitional flows created in the glottis. The human airway models are reconstructed from CT volumetric images, and the subject-specific boundary condition is imposed to the 3D ending branches with the aid of an image registration technique. As a result, several constricted airways are captured in CT images of severe asthmatic subjects, causing significant pressure drop with high air speed because the constriction of airways creates high flow resistance. The simulated instantaneous velocity fields obtained are then employed to track transport and deposition of 2.5 μm particles. It is found that high flow resistance regions are correlated with high particle-deposition regions. In other words, the constricted airways can induce high airway resistance and subsequently increase particle deposition in the regions. This result may be applied to understand the characteristics of deposition of pharmaceutical aerosols or bacteria. This work was supported in part by NIH grants R01-HL094315 and S10-RR022421.

    Bronchoconstriction in asthma results in patchy ventilation forming ventilation defects (VDefs). Patchy ventilation is clinically important because it affects obstructive symptoms and impairs both gas exchange and the distribution of inhaled medications. The current study combined functional imaging, oscillatory mechanics and theoretical modelling to test whether the degrees of constriction of airways feeding those units outside VDefs were related to the extent of VDefs in bronchoconstricted asthmatic subjects. Positron emission tomography was used to quantify the regional distribution of ventilation and oscillatory mechanics were measured in asthmatic subjects before and after bronchoconstriction. For each subject, ventilation data was mapped into an anatomically based lung model that was used to evaluate whether airway constriction patterns, consistent with the imaging data, were capable of matching the measured changes in airflow obstruction. The degree and heterogeneity of constriction of the airways feeding alveolar units outside VDefs was similar among the subjects studied despite large inter-subject variability in airflow obstruction and the extent of the ventilation defects. Analysis of the data amongst the subjects showed an inverse relationship between the reduction in mean airway conductance, measured in the breathing frequency range during bronchoconstriction, and the fraction of lung involved in ventilation defects. The current data supports the concept that patchy ventilation is an expression of the integrated system and not just the sum of independent responses of individual airways.

    AIM: To determine the expressions of cysteinyl leukotriene receptors, CysLT1 and CysLT2, in airway eosinophilic inflammation of OVA-induced asthmatic mice and the modulation by montelukast, a CysLT1 receptor antagonist.METHODS: Asthma model was induced by chronic exposure to ovalbumin (OVA) in C57BL/6 mice. The eosinophils in bronchoalveolar lavage (BAL) fluid and lung tissues were counted, IL-5 level in BAL fluid was measured,and CysLT1 and CysLT2 receptor mRNA expressions were detected by semi-quantitative RT-PCR. RESULTS:Montelukast (6 mg/kg, once per day for 20 d) significantly suppressed the increased eosinophils in BAL fluid and lung tissue, and increased IL-5 level in BAL fluid in OVA challenged mice. OVA challenge increased CysLT1 but decreased CysLT2 receptor mRNA expression. Montelukast inhibited the increased CysLT1 but not the reduced CysLT2 expression after OVA challenge. CONCLUSION: CysLT receptors are modulated immunologically, and montelukast inhibits up-regulation of CysLT1 receptor and airway eosinophilic inflammation in asthmatic mice.

    This paper aims to investigate the effect of Toll-like receptors 3 (TLR3)/TIR-domain-containing adapter-inducing interferon-β (TRIF) signal pathway on the airway inflammation and remodeling in asthmatic mice. C57BL/6 and TLR3(-/-) mice were randomly divided into three groups (10 mice per group), including Control group (mice inhaled phosphate buffer saline (PBS)), Asthma group (mice inhaled ovalbumin (OVA)) and polyriboinosinic-ribocytidylic acid (poly (I: C)) group (asthmatic mice were injected intraperitoneally with TLR3 agonist poly (I: C)). Hematoxylin-eosin (HE) staining, Wright-Giemsa staining, Enzyme-linked immunosorbent assay (ELISA), Immunohistochemistry, Hydroxyproline assay, quantitative real time polymerase chain reaction (qRT-PCR) and Western blot were used to assess for the indices of airway inflammation and remodeling. In terms of WT mice, all asthma groups with or without the addition of poly (I: C) showed exaggerated inflammation and remodeling in the airways as compared to Control group, which were more seriously in poly (I: C) group than Asthma group. Furthermore, we observed the significant inhibition of airway inflammation and remodeling in the TLR3(-/-) mice in both Asthma no matter with or without addition of poly (I: C) than the WT mice. TLR3 knockout could obviously relieve the airway inflammation and remodeling in asthma through inhibiting TLR3/TRIF signaling pathway.

    Full Text Available Richard F Wagner Jr, Sharon S Raimer, Brent C Kelly Department of Dermatology, The University of Texas Medical Branch, Galveston, Texas, USA Abstract: Programmatic changes for the dermatology residency program at The University of Texas Medical Branch were first introduced in 2005, with the faculty goal incorporating formal dermatology research projects into the 3-year postgraduate training period. This curriculum initially developed as a recommendation for voluntary scholarly project activity by residents, but it evolved into a program requirement for all residents in 2009. Departmental support for this activity includes assignment of a faculty mentor with similar interest about the research topic, financial support from the department for needed supplies, materials, and statistical consultation with the Office of Biostatistics for study design and data analysis, a 2-week elective that provides protected time from clinical activities for the purpose of preparing research for publication and submission to a peer-reviewed medical journal, and a departmental award in recognition for the best resident scholarly project each year. Since the inception of this program, five classes have graduated a total of 16 residents. Ten residents submitted their research studies for peer review and published their scholarly projects in seven dermatology journals through the current academic year. These articles included three prospective investigations, three surveys, one article related to dermatology education, one retrospective chart review, one case series, and one article about dermatopathology. An additional article from a 2012 graduate about dermatology education has also been submitted to a journal. This new program for residents was adapted from our historically successful Dermatology Honors Research Program for medical students at The University of Texas Medical Branch. Our experience with this academic initiative to promote dermatology research by

    Full Text Available In many recent studies in the literature have described and commented on “competency based resident training” in pathology. According to this model, competencies are subclassified in 6 main categories: Patient care, medical knowledge, practice based learning and improvement, interpersonal and communication skills, professionalism, and systems based practice. Assessment of competency forms the main component of this model.Under the framework of Ankara Society of Pathology, a working group, composed of 11 residents, 6 of which representing the Training and Research Hospitals of Ministry of Health and the rest representing the university hospitals in Ankara, was established in order to participate in the think-tank about resident training in pathology. A questionnaire, composed of 12 questions, was prepared. According to this questionnaire, the number of trainers in the university hospitals is much higher than in the commercial hospitals. While the total number of cases and cases per resident do not differ between the university and commercial hospitals, microscopes used for the educational purposes are significantly less in the commercial hospitals, that is due to less number of binocular microscopes. The amount of resident training program, which consists of intra and intersectional meetings, are similar in the university and commercial hospitals, however, theoretic lectures are given only in 3 departments. Residents working in the university hospitals have obviously heavier burden than in the commercial hospitals. Lastly, residents generally exclaimed that the time dedicated to the macroscopy training is less sufficient than time used for the microscopy training.The factors affecting the training of resident in pathology are divided into two main groups: 1 Factors directly affecting training (quality of trainer, time dedicated for education, feed back, eg. and 2 Conditions which waste residents' time.

    Full Text Available Electronic cigarettes (e-cigs are marketed as safer alternatives to tobacco cigarettes and have shown to reduce their consumption. Here we report for the first time the effects of e-cigs on subjective and objective asthma parameters as well as tolerability in asthmatic smokers who quit or reduced their tobacco consumption by switching to these products. We retrospectively reviewed changes in spirometry data, airway hyper-responsiveness (AHR, asthma exacerbations and subjective asthma control in smoking asthmatics who switched to regular e-cig use. Measurements were taken prior to switching (baseline and at two consecutive visits (Follow-up/1 at 6 (±1 and Follow-up/2 at 12 (±2 months. Eighteen smoking asthmatics (10 single users, eight dual users were identified. Overall there were significant improvements in spirometry data, asthma control and AHR. These positive outcomes were noted in single and dual users. Reduction in exacerbation rates was reported, but was not significant. No severe adverse events were noted. This small retrospective study indicates that regular use of e-cigs to substitute smoking is associated with objective and subjective improvements in asthma outcomes. Considering that e-cig use is reportedly less harmful than conventional smoking and can lead to reduced cigarette consumption with subsequent improvements in asthma outcomes, this study shows that e-cigs can be a valid option for asthmatic patients who cannot quit smoking by other methods.

  1. IL-4 increases type 2, but not type 1, cytokine production in CD8+ T cells from mild atopic asthmatics

    2005-07-01

    Full Text Available Abstract Background Virus infections are the major cause of asthma exacerbations. CD8+ T cells have an important role in antiviral immune responses and animal studies suggest a role for CD8+ T cells in the pathogenesis of virus-induced asthma exacerbations. We have previously shown that the presence of IL-4 during stimulation increases the frequency of IL-5-positive cells and CD30 surface staining in CD8+ T cells from healthy, normal subjects. In this study, we investigated whether excess IL-4 during repeated TCR/CD3 stimulation of CD8+ T cells from atopic asthmatic subjects alters the balance of type 1/type 2 cytokine production in favour of the latter. Methods Peripheral blood CD8+ T cells from mild atopic asthmatic subjects were stimulated in vitro with anti-CD3 and IL-2 ± excess IL-4 and the expression of activation and adhesion molecules and type 1 and type 2 cytokine production were assessed. Results Surface expression of very late antigen-4 [VLA-4] and LFA-1 was decreased and the production of the type 2 cytokines IL-5 and IL-13 was augmented by the presence of IL-4 during stimulation of CD8+ T cells from mild atopic asthmatics. Conclusion These data suggest that during a respiratory virus infection activated CD8+ T cells from asthmatic subjects may produce excess type 2 cytokines and may contribute to asthma exacerbation by augmenting allergic inflammation.

Allergic asthma is associated with the production of allergen-specific IgE and expansion of allergen-specific T-cell populations. Progression of allergic inflammation is driven by T-helper type 2 (Th2 mediators and is associated with alterations in the levels of lipid mediators. OBJECTIVES: Responses of the respiratory system to birch allergen provocation in allergic asthmatics were investigated. Eicosanoids and other oxylipins were quantified in the bronchoalveolar lumen to provide a measure of shifts in lipid mediators associated with allergen challenge in allergic asthmatics. METHODS: Eighty-seven lipid mediators representing the cyclooxygenase (COX, lipoxygenase (LOX and cytochrome P450 (CYP metabolic pathways were screened via LC-MS/MS following off-line extraction of bronchoalveolar lavage fluid (BALF. Multivariate statistics using OPLS were employed to interrogate acquired oxylipin data in combination with immunological markers. RESULTS: Thirty-two oxylipins were quantified, with baseline asthmatics possessing a different oxylipin profile relative to healthy individuals that became more distinct following allergen provocation. The most prominent differences included 15-LOX-derived ω-3 and ω-6 oxylipins. Shared-and-Unique-Structures (SUS-plot modeling showed a correlation (R(2 = 0.7 between OPLS models for baseline asthmatics (R(2Y[cum] = 0.87, Q(2[cum] = 0.51 and allergen-provoked asthmatics (R(2Y[cum] = 0.95, Q(2[cum] = 0.73, with the majority of quantified lipid mediators and cytokines contributing equally to both groups. Unique structures for allergen provocation included leukotrienes (LTB(4 and 6-trans-LTB(4, CYP-derivatives of linoleic acid (epoxides/diols, and IL-10. CONCLUSIONS: Differences in asthmatic relative to healthy profiles suggest a role for 15-LOX products of both ω-6 and ω-3 origin in allergic

    The revised ABR board certification process has updated the method by which diagnostic radiology residents are evaluated for competency in clinical radiologic physics. In this work, the author reports the successful design and implementation of a resident-taught physics course consisting of 5 weekly, hour-long lectures intended for incoming first-year radiology residents in their first month of training. To the author's knowledge, this is the first description of a course designed to provide a very early framework for ongoing physics education throughout residency without increasing the didactic burden on faculty members. Twenty-six first-year residents spanning 2 academic years took the course and reported subjective improvement in their knowledge (90%) and interest (75%) in imaging physics and a high level of satisfaction with the use of senior residents as physics educators. Based on the success of this course and the minimal resources required for implementation, this work may serve as a blueprint for other radiology residency programs seeking to develop revised physics curricula.

    Medical resident education in the United States has been a matter of national priority for decades, exemplified initially through the Liaison Committee for Graduate Medical Education and then superseded by the Accreditation Council for Graduate Medical Education. A recent Special Report in the New England Journal of Medicine, however, has described resident educational programs to date as prescriptive, noting an absence of innovation in education. Current aims of contemporary medical resident education are thus being directed at ensuring quality in learning as well as in patient care. Achievement and work-motivation theories attempt to explain people's choice, performance, and persistence in tasks. Expectancy Theory as one such theory was reviewed in detail, appearing particularly applicable to surgical residency training. Correlations between Expectancy Theory as a work-motivation theory and residency education were explored. Understanding achievement and work-motivation theories affords an opportunity to gain insight into resident motivation in training. The application of Expectancy Theory in particular provides an innovative perspective into residency education. Afforded are opportunities to promote the development of programmatic methods facilitating surgical resident motivation in education.

    Full Text Available In the United States and Europe, gastroesophageal reflux (GER is receiving attention as a potential cause of bronchial asthma. Few Japanese case reports have described this relationship. Therefore, we investigated the effect of omeprazole and cisapride on pulmonary function tests, blood gases and home peak expiratory flow rates (PEFR in six Japanese outpatients with asthma and proven GER. After 8 weeks of treatment, reflux esophagitis had improved in all patients. However, the parameters of pulmonary function showed no change other than a significant post- treatment increase in home PEFR (4.4-27.7% in three patients. These results suggest that anti-reflux (omeprazole and cisapride treatment will produce small improvements in the PEFR in some Japanese asthmatics with GER.

    Full Text Available Adrenal suppression secondary to prolonged inhaled corticosteroid use is usually limited to biochemical abnormalities, with no obvious clinical effects. Acute adrenal crisis is much rarer event but has been reported with increasing frequency. We report a case of a 7-year-old asthmatic child who presented with an acute history of lethargy after a respiratory infection. He was maintained on 220 g/day of fluticasone propionate for several years. Initial evaluation revealed severe adrenal suppression, with undetectable cortisol levels and minimal response after stimulation with ACTH. After fluticasone was discontinued, a gradual recovery of the adrenal axis was seen. This case shows that acute adrenal crisis may be a consequence even at the usual prescribed doses, stressing the importance of using the lowest dose of inhaled steroids needed to control symptoms and having an increased awareness of this complication.

    As human life expectancy has improved rapidly in industrialized societies, age-related cognitive impairment presents an increasing challenge. Targeting histopathological processes that correlate with age-related cognitive declines, such as neuroinflammation, low levels of neurogenesis, disrupted blood-brain barrier and altered neuronal activity, might lead to structural and functional rejuvenation of the aged brain. Here we show that a 6-week treatment of young (4 months) and old (20 months) rats with montelukast, a marketed anti-asthmatic drug antagonizing leukotriene receptors, reduces neuroinflammation, elevates hippocampal neurogenesis and improves learning and memory in old animals. By using gene knockdown and knockout approaches, we demonstrate that the effect is mediated through inhibition of the GPR17 receptor. This work illustrates that inhibition of leukotriene receptor signalling might represent a safe and druggable target to restore cognitive functions in old individuals and paves the way for future clinical translation of leukotriene receptor inhibition for the treatment of dementias.

    Full Text Available The objective. was to investigate L-Carnitine level and the effects of its supplementation in children with moderate persistent Asthma. Methods. Free and total serum carnitine levels were measured in 50 children having moderate persistent asthma and 50 healthy control children. The patients group was randomly divided into two subgroups. Subgroup A was supplemented with L-carnitine for 6 months while subgroup B was used as a placebo controls. Both subgroups were assessed by pulmonary function tests (PFT and childhood-asthma control test (C-ACT before and 6 months after carnitine supplementation. Results. Total and free carnitine levels were significantly lower in patient group than in control group. PFT and C-ACT showed significant improvements in asthmatic children supplemented with L-carnitine than in those who were not supplemented. Conclusion. L-carnitine levels were initially lower in moderate persistent asthmatic children as compared to healthy control children. Asthmatic children who received L-carnitine supplementation showed statistically significant improvement of C-ACT and PFT.

    Full Text Available Background. A reliable asthma diagnosis is challenging in preschool wheezing children. As inhaled corticosteroids (ICS are more effective in asthmatics than in children with transient wheeze, an ICS response might be helpful in early asthma diagnosis. Methods. 175 children (aged two–four years with recurrent wheeze received 200 μg Beclomethasone extra-fine daily for eight weeks. Changes in Exhaled Breath Condensate (EBC biomarkers (pH, interleukin (IL-1α, IL-2, IL-4, IL-5, IL-10, IFN-γ, sICAM, and CCL-11, Fractional exhaled Nitric Oxide (FeNO, airway resistance, and symptoms were assessed. At six years of age a child was diagnosed as transient wheezer or asthmatic. Adjusted logistic regression analysis was performed with multiple testing correction. Results. 106 transient wheezers and 64 asthmatics were analysed at six years of age. Neither changes in EBC biomarkers, nor FeNO, airway resistance, or symptoms during ICS trial at preschool age were related to asthma diagnosis at six years of age. However, asthmatics had more airway symptoms before the start of the ICS trial than transient wheezers (P<0.01. Discussion. Although symptom score in preschool wheezing children at baseline was associated with asthma at six years of age, EBC biomarkers, airway resistance, or symptom response to ICS at preschool age could not predict asthma diagnosis at six years of age.

    Full Text Available Background: Pediatric health research is important for improving the health and well-being of children and their families. To foster the development of physicians’ research competencies, it is vital to integrate practical and context-specific research training into residency programs. Purpose: To describe the development of a resident research training program at one tertiary care pediatric academic health sciences center in Ontario, Canada. Methods: We surveyed residents and pediatricians/research staff to establish the need and content for a resident research training program. Results: Residents and resident research supervisors agreed or strongly agreed that research training is important for residents. However, few residents and supervisors believed that their academic health sciences center provided adequate training and resources to support resident research. As such, an online resident research training program was established. Residents and supervisors agreed that the program should focus on the following topics: 1 critically evaluating research literature, 2 writing a research proposal, 3 submitting an application for research funding, and 4 writing a manuscript. Discussion: This highly accessible, context-specific, and inexpensive online program model may be of interest and benefit to other residency programs as a means to enhance residents’ scholarly roles. A formal evaluation of the research training program is now underway.

    2004-01-01

    Summary: The inhibitive effects of all-trans retinoic acid (ARTA) on airway inflammation in asthmatic rats and its mechanism on the basis of the regulation of nuclear factor kappaB (NF-κB) were explored. Thirty-two SD rats were randomly divided into 4 groups: control group, asthma group,dexamethasone treatment group and retinotic acid treatment group. The total and differential cell counts in the collected bronchoalveolar lavage fluid (BALF) were measured. The pathological changes in lung tissues were estimated by scoring. The expression of NF-κB inhibitor (IκBa), NF-κB,intercellular adhering molecule-1 (ICAM-1) in lung tissue was detected by immunohistochemical method. The results showed that in the two treatment groups, the total cell counts and proportion of inflammatory cells in BALF were significantly reduced, but there was no significant difference in differential cell counts in BALF between, them. The pathological changes in lung tissues in the treatment groups were significantly attenuated as compared with asthma group. Except the epithelial injury in retinotic acid treatment group was milder than in dexamethasone treatment group, the remaining lesions showed no significant difference between them. In the two treatment groups, the expression of IκBa was increased, while the expression of NF-κB and ICAM-1 decreased with the difference between the two groups being not significant. It was concluded that the similar anti-inflammatory effects and mechanism of ATRA on airway in asthmatic rats to those of dexamethasone were contributed to the increase of cytoplasmic IκBa content and suppression of NF-cB activation and expression.

  4. Phenotypic responses of differentiated asthmatic human airway epithelial cultures to rhinovirus.

    Full Text Available Human airway epithelial cells are the principal target of human rhinovirus (HRV, a common cold pathogen that triggers the majority of asthma exacerbations. The objectives of this study were 1 to evaluate an in vitro air liquid interface cultured human airway epithelial cell model for HRV infection, and 2 to identify gene expression patterns associated with asthma intrinsically and/or after HRV infection using this model.Air-liquid interface (ALI human airway epithelial cell cultures were prepared from 6 asthmatic and 6 non-asthmatic donors. The effects of rhinovirus RV-A16 on ALI cultures were compared. Genome-wide gene expression changes in ALI cultures following HRV infection at 24 hours post exposure were further analyzed using RNA-seq technology. Cellular gene expression and cytokine/chemokine secretion were further evaluated by qPCR and a Luminex-based protein assay, respectively.ALI cultures were readily infected by HRV. RNA-seq analysis of HRV infected ALI cultures identified sets of genes associated with asthma specific viral responses. These genes are related to inflammatory pathways, epithelial structure and remodeling and cilium assembly and function, including those described previously (e.g. CCL5, CXCL10 and CX3CL1, MUC5AC, CDHR3, and novel ones that were identified for the first time in this study (e.g. CCRL1.ALI-cultured human airway epithelial cells challenged with HRV are a useful translational model for the study of HRV-induced responses in airway epithelial cells, given that gene expression profile using this model largely recapitulates some important patterns of gene responses in patients during clinical HRV infection. Furthermore, our data emphasize that both abnormal airway epithelial structure and inflammatory signaling are two important asthma signatures, which can be further exacerbated by HRV infection.

    We compared the effects of pretreatment with saline, ipratropium bromide, and disodium cromoglycate (DSCG) on bronchoconstriction induced by methoxamine--an alpha-adrenoceptor agonist, in asthmatic subjects. All 12 patients bronchoconstricted in response to methoxamine after saline. The PD20 (the dose of methoxamine causing a 20% fall in forced expiratory volume in 1 s [FEV1]) ranged from 0.3-18 mumol. Ipratropium bromide (200 micrograms administered by aerosol) significantly inhibited (P less than 0.05) the response to methoxamine in all patients without producing significant changes in the mean baseline lung function. The mean PD20 for methoxamine after saline was 6.8 mumol and 95% confidence limits (CL) were 3.6, 12.7 mumol. The mean PD20 for methoxamine after ipratropium bromide was 35.4 (95% CL 28.8, 43.6) mumol. DSCG also produced significant (P less than 0.05) shifts to the right in the methoxamine dose response curves, but did not affect resting airway calibre as measured by the FEV1. The mean PD20 for methoxamine increased from 3.3 mumol (95% CL 1.1, 10.0 mumol) after saline to 25.1 mumol (95% CL 14.1, 44.6) after DSCG pretreatment. These findings suggest that alpha-adrenoceptors in the airways of asthmatic subjects may be located at sites other than smooth muscle--possibly on mast cells but more likely on nerve endings and/or parasympathetic ganglia.

    In previous studies, the relaxant, anticholinergic (functional antagonism) antihistaminic, effects of Nigella sativa have been demonstrated on guinea-pig tracheal chains. In the present study, the prophylactic effect of boiled extract of N. sativa on asthmatic disease was examined. Twenty-nine asthmatic adults were randomly divided into control group (14 patients) and study group (15 patients), and they were studied for 3 months. In the study group 15 mL/kg of 0.1 g% boiled extract and in the control group a placebo solution was administrated daily throughout the study. Asthma symptom score, asthma severity, frequency of symptoms/week and wheezing were recorded in the beginning (first visit), 45 days after treatment (second visit), and at the end of the study (third visit). Pulmonary function tests (PFTs) were also measured, and the drug regimen of the patients was evaluated at three different visits. All asthma symptoms, frequency of asthma symptoms/week, chest wheezing, and PFT values in the study group significantly improved in the second and third visits compared with the first visit (P < 0.05 to P < 0.001). In addition, further improvement of chest wheezing and severity of disease on the third visit were observed compared with the second visit in this group (P < 0.05 for both cases). In the third visit all symptoms in the study group were significantly different from those of the control group (P < 0.01 to P < 0.001). However, in the control group, there were only small improvements in some parameters in just the second visit. The usage of inhaler and oral beta-agonists, oral corticosteroid, oral theophylline and even inhaler corticosteroid in the study group decreased at the end of the study while there were no obvious changes in usage of the drugs in control subjects. The results of phase I study generally suggest a prophylactic effect of N. sativa on asthma disease and warrant further research regarding this effect.

    Cromolyn sodium, a mast cell stabilizing agent, provides an immediate protective effect against the exercise-induced bronchoconstriction while being used before the exercise. However, cromolyn is ineffective in reversing asthmatic bronchospasm; it is used as a maintenance therapy and has a prophylactic role in chronic asthma. The purpose of this study was to determine the extent of change in baseline lung function tests following a single dose of cromolyn sodium in adult asthmatics. Forty volunteers (33 women and 7 men) with moderate to severe persistent asthma were randomly assigned to receive 20 mg cromolyn, 40 mg cromolyn or cromolyn-placebo. The percent of improvement in lung function parameters was compared among the groups, during 1 h of inhalation. Low dose of cromolyn induced more improvement in most lung function parameters such as forced expiratory flow volume in one second, forced vital capacity and peak expiratory flow compared with other groups. After 15 min, the improvement percentage of baseline forced expiratory flow volume in one second was 3.35 ± 1.5, for sodium cromoglycate-20 mg group compared with 0.98 ± 1.43 and - 0.68 ± 1.2 for sodium cromoglycate-placebo and sodium cromoglycate-40 mg, groups respectively. However, the differences between means were not significant. Furthermore, based on the definition of American Thoracic Society (ATS) for a "significant post-bronchodilator response" developed in a few patients 15 min after the inhalation of 20 mg cromolyn sodium. It is suggested that probably the inhalation of 20 mg of cromolyn sodium could immediately improve the lung function in few adults with asthma.

    Mangiferin is a major bioactive ingredient in Mangifera indica Linn. (Anacardiaceae) leaves. Aqueous extract of such leaves have been used as an indigenous remedy for respiratory diseases like asthma and coughing in traditional Chinese medicine. However, underlying molecular mechanisms of mangiferin on anti-asthma remain unclear. In our present study, we investigated the anti-asthmatic effect of mangiferin on Th1/Th2 cytokine profiles and explored its underlying immunoregulatory mechanism in mouse model of allergic asthma. Mangiferin significantly reduced the total inflammatory cell counts and eosinophil infiltration, decreased the production of ovalbumin-specific IgE in serum and PGD2 in BALF. The antibody array analysis showed that mangiferin down-regulated the levels of one group of cytokines/chemokines including Th2-related IL-4, IL-5, IL-13, and others IL-3, IL-9, IL-17, RANTES, TNF-α, but simultaneously up-regulated Th1-related IFN-γ, IL-2 and IL-10 and IL-12 expression in serum. Thus it attenuates the imbalance of Th1/Th2 cells ratio by diminishing the abnormal mRNA levels of Th1 cytokines (IFN-γ and IL-12) and Th2 cytokines (IL-4, IL-5 and IL-13). Finally, mangiferin substantially inhibited the activation and expression of STAT-6 and GATA-3 in excised lung tissues. Our results suggest that mangiferin can exert anti-asthmatic effect. The underlying mechanism may attribute to the modulation of Th1/Th2 cytokine imbalance via inhibiting the STAT6 signaling pathway. PMID:24955743

    Full Text Available Mangiferin is a major bioactive ingredient in Mangifera indica Linn. (Anacardiaceae leaves. Aqueous extract of such leaves have been used as an indigenous remedy for respiratory diseases like asthma and coughing in traditional Chinese medicine. However, underlying molecular mechanisms of mangiferin on anti-asthma remain unclear. In our present study, we investigated the anti-asthmatic effect of mangiferin on Th1/Th2 cytokine profiles and explored its underlying immunoregulatory mechanism in mouse model of allergic asthma. Mangiferin significantly reduced the total inflammatory cell counts and eosinophil infiltration, decreased the production of ovalbumin-specific IgE in serum and PGD2 in BALF. The antibody array analysis showed that mangiferin down-regulated the levels of one group of cytokines/chemokines including Th2-related IL-4, IL-5, IL-13, and others IL-3, IL-9, IL-17, RANTES, TNF-α, but simultaneously up-regulated Th1-related IFN-γ, IL-2 and IL-10 and IL-12 expression in serum. Thus it attenuates the imbalance of Th1/Th2 cells ratio by diminishing the abnormal mRNA levels of Th1 cytokines (IFN-γ and IL-12 and Th2 cytokines (IL-4, IL-5 and IL-13.

    Asthma is a disease characterized by inflammation which affects both proximal and distal airways. We evaluated the prevalence of small airway obstruction (SAO) in a group of clinically stable asthmatics with both normal forced expiratory volume in the first second (FEV1) and normal FEV1/forced vital capacity (FVC) and treated with an association of inhaled corticosteroids (ICSs) and long acting β2-agonists (LABAs). Clinical evaluation included the measurement of dyspnea, asthma control test and drug compliance. The prevalence of SAO was estimated by spirometry and plethysmography and defined by the presence of one or more of the following criteria: functional residual capacity (FRC) > 120% predicted (pred), residual volume (RV) > pred + 1.64 residual standard deviation (RSD), RV/total lung capacity (TLC) > pred + 1.64 RSD, forced expiratory flow (FEF)25-75% slow vital capacity (SVC) - FVC > 10%. Among the 441 patients who were included, 222 had normal FEV1 and FEV1/FVC. At least one criteria of SAO was found in 115 (52%) mainly lung hyperinflation (39% based on high FRC, RV or RV/TLC) and more rarely distal airflow limitation (15% based on FEF25-75% or FEF50%) or expiratory trapping (10% based on increased SVC - FVC). In the patients with only SAO (no PAO), there was no relationship between SAO, asthma history and the scores of dyspnea, asthma control or drug compliance. These results suggest that in asthmatics with normal FEV1 and FEV1/FVC, treated with ICSs and LABAs, SAO is found in more than half of the patients indicating that the routinely used lung function tests can underestimate dysfunctions occurring in the small airways.

    Episodes of acute exacerbation are the major clinical feature of asthma and therefore represent an important focus for developing novel therapies for this disease. There are many reports that the n-3 fatty acids found in fish oil exert anti-inflammatory effects, but there are few studies of the action of fish oil on airway smooth muscle (ASM) function. In the present investigation, we evaluated the effect of fish oil supplementation on smooth muscle force of contraction in ovalbumin-induced asthmatic Wistar rats, and its consequences on static lung compliance, mucus production, leukocyte chemotaxis and production of proinflammatory cytokines. Fish oil supplementation suppressed the infiltration of inflammatory cells into the lung in asthmatic animals (2.04 ± 0.19 × 10(6) cells vs. 3.33 ± 0.43 × 10(6) cells in the control asthmatic group; P < 0.05). Static lung compliance increased with fish oil supplementation in asthmatic rats (0.640 ± 0.053 mL/cm H2O vs. 0.399 ± 0.043 mL/cm H2O; P < 0.05). However, fish oil did not prevent asthma-associated lung eosinophilia and did not affect the concentrations of tumor necrosis factor-α and interleukin-1β in lung tissue or the proportion of the airways obliterated with mucus. Fish oil had no effect on the force of contraction in asthmatic rats in response to acetylcholine (3.026 ± 0.274 mN vs. 2.813 ± 0.364 mN in the control asthmatic group). In conclusion, although fish oil exerts some benefits in this model of asthma, its effectiveness appears to be limited by an inefficient action on airway smooth muscle function.

    Full Text Available Abstract Background Despite intensive studies focused on the pathophysiology of asthmatic inflammation, little is known about how cross-talk between neuroendocrine and immune systems regulates the inflammatory response during an asthmatic attack. We recently showed corresponding changes of cytokines and leukotriene B4 (LTB4 in brain and lung tissues of antigen-challenged asthmatic rats. Here, we investigated how LTB4 interacts with the neuroendocrine-immune system in regulating antigen-induced asthmatic responses in sensitized guinea pigs. Methods Ovalbumin-sensitized guinea pigs were challenged by inhalation of antigen. Vehicle, LTB4 or U75302 (a selective LTB4 BLT1 receptor inhibitor was given via intracerebroventricular injection (i.c.v. 30 min before challenge. Airway contraction response was evaluated using Penh values before and after antigen challenge. The inflammatory response in lung tissue was evaluated 24 h after challenge. The LTB4 content of lung and brain homogenate preparations was detected by reversed phase high-performance liquid chromatography (RP-HPLC. Plasma levels of adrenocorticotropic hormone (ACTH and corticosterone (CORT were measured using ELISA kits. Results Antigen challenge impaired pulmonary function and increased inflammatory cell infiltration in lung tissue. These responses could be significantly suppressed by LTB4, 30 ng i.c.v., in ovalbumin-sensitized guinea pigs. LTB4 content of lung and brain homogenates from antigen-challenged guinea pigs was significantly increased. In addition, administration of LTB4 via i.c.v. markedly increased CORT and ACTH level in plasma before antigen challenge, and there were further increases in CORT and ACTH levels in plasma after antigen challenge. U75302, 100 ng i.c.v., completely blocked the effects of LTB4. In addition, U75302, 100 ng via i.c.v. injection, markedly decreased LTB4 content in lung homogenates, but not in brain homogenates. Conclusions Increased LTB4 levels in

    Background Corticosteroids remain the most effective therapy available for asthma. They have widespread effects on asthmatic airway inflammation. However, little is known about the effects of corticosteroids on the production of bone marrow inflammatory cells in asthma. This study observed the effects of glucocorticoid and cysteinyl leukotriene 1 receptor antagonist on CD34 + hematopoietic cells, so as to explore the possible effectiveness of a bone marrow-targeted anti-inflammatory strategy.Methods Balb/c mice were sensitized and challenged with ovalbumin (OVA) to establish an asthmatic model. For two consecutive weeks, asthmatic mice were challenged with OVA while being given either prednisone, montelukast, prednisone plus montelukast, or sterile saline solution. The mice were killed 24 hours after the last challenge with OVA, and bronchoalveolar lavage fluid (BALF),peripheral blood, and bone marrow were collected. Eosinophils in peripheral blood and BALF, and nucleated cells in BALF, peripheral blood, and bone marrow were counted. The percentages of CD34+cells, CD4 + T lymphocytes and CD8 + T lymphocytes among nucleated cells in peripheral blood and bone marrow were counted by flow cytometry. Immunocytochemistry and in situ hybridization were employed to detect expression of CD34 and interleukin (IL)-5Rαx mRNA (CD34 + IL-5Rα mRNA+ cells)among bone marrow hematopoietic cells.Results Compared with the sterile saline solution group, the number of eosinophils in BALF and peripheral blood, CD34 + cells in peripheral blood and bone marrow, and CD34 + IL-5Rc mRNA+ cells in bone marrow of mice from the prednisone and prednisone plus montelukast groups were significantly lower (P<0.01). The number of eosinophils in BALF from the montelukast group was also significantly lower (P<0.05).Conclusions The results suggest that, in this asthmatic mouse model, prednisone probably inhibits proliferation, differentiation, and migration of CD34 + cells in bone marrow, blocks

A recent Special Report in the New England Journal of Medicine, however, has described resident educational programs to date as prescriptive, noting an absence of innovation in education. Current aims of contemporary medical resident education are thus being directed at ensuring quality in learning as well as in patient care. Achievement and work-motivation theories attempt to explain people's choice, performance, and persistence in tasks. Expectancy Theory as one such theory was reviewed in detail, appearing particularly applicable to surgical residency training. Correlations between Expectancy Theory as a work-motivation theory and residency education were explored. Understanding achievement and work-motivation theories affords an opportunity to gain insight into resident motivation in training. The application of Expectancy Theory in particular provides an innovative perspective into residency education. Afforded are opportunities to promote the development of programmatic methods facilitating surgical resident motivation in education. Keywords: learning, education, achievement

    2010-08-01

    Full Text Available Abstract Background The inhalation of allergens by allergic asthmatics results in the early asthmatic response (EAR, which is characterized by acute airway obstruction beginning within a few minutes. The EAR is the earliest indicator of the pathological progression of allergic asthma. Because the molecular mechanism underlying the EAR is not fully defined, this study will contribute to a better understanding of asthma. Methods In order to gain insight into the molecular basis of the EAR, we examined changes in protein expression patterns in the lung tissue of asthmatic rats during the EAR using 2-DE/MS-based proteomic techniques. Bioinformatic analysis of the proteomic data was then performed using PPI Spider and KEGG Spider to investigate the underlying molecular mechanism. Results In total, 44 differentially expressed protein spots were detected in the 2-DE gels. Of these 44 protein spots, 42 corresponded to 36 unique proteins successfully identified using mass spectrometry. During subsequent bioinformatic analysis, the gene ontology classification, the protein-protein interaction networking and the biological pathway exploration demonstrated that the identified proteins were mainly involved in glycolysis, calcium binding and mitochondrial activity. Using western blot and semi-quantitative RT-PCR, we confirmed the changes in expression of five selected proteins, which further supports our proteomic and bioinformatic analyses. Conclusions Our results reveal that the allergen-induced EAR in asthmatic rats is associated with glycolysis, calcium binding and mitochondrial activity, which could establish a functional network in which calcium binding may play a central role in promoting the progression of asthma.

  3. Pentraxin 3 (PTX3 expression in allergic asthmatic airways: role in airway smooth muscle migration and chemokine production.

    Directory of Open Access Journals (Sweden)

    Jingbo Zhang

    Full Text Available BACKGROUND: Pentraxin 3 (PTX3 is a soluble pattern recognition receptor with non-redundant functions in inflammation and innate immunity. PTX3 is produced by immune and structural cells. However, very little is known about the expression of PTX3 and its role in allergic asthma. OBJECTIVES AND METHODS: We sought to determine the PTX3 expression in asthmatic airways and its function in human airway smooth muscle cells (HASMC. In vivo PTX3 expression in bronchial biopsies of mild, moderate and severe asthmatics was analyzed by immunohistochemistry. PTX3 mRNA and protein were measured by real-time RT-PCR and ELISA, respectively. Proliferation and migration were examined using (3H-thymidine incorporation, cell count and Boyden chamber assays. RESULTS: PTX3 immunoreactivity was increased in bronchial tissues of allergic asthmatics compared to healthy controls, and mainly localized in the smooth muscle bundle. PTX3 protein was expressed constitutively by HASMC and was significantly up-regulated by TNF, and IL-1β but not by Th2 (IL-4, IL-9, IL-13, Th1 (IFN-γ, or Th-17 (IL-17 cytokines. In vitro, HASMC released significantly higher levels of PTX3 at the baseline and upon TNF stimulation compared to airway epithelial cells (EC. Moreover, PTX3 induced CCL11/eotaxin-1 release whilst inhibited the fibroblast growth factor-2 (FGF-2-driven HASMC chemotactic activity. CONCLUSIONS: Our data provide the first evidence that PTX3 expression is increased in asthmatic airways. HASMC can both produce and respond to PTX3. PTX3 is a potent inhibitor of HASMC migration induced by FGF-2 and can upregulate CCL11/eotaxin-1 release. These results raise the possibility that PTX3 may play a dual role in allergic asthma.

The injection of P.major extract and theophylline was administered intraperitoneally for four weeks. At the end of the treatment, all of the rats were sacrificed and lungs were taken out, fixed, and stained with H&E, toluidine blue, and PAS, then histological studies were followed with light microscope. Results: Results showed that, in asthmatic group, the mean number of mast cells was significantly increased (p<0.05. Thickness of alveolar epithelium and accumulation of glycoprotein in airways was increased. Moreover, in some of alveolar sac hemorrhaging was observed. Administration of p.major extract in asthmatic rats restored these changes towards normal group.Conclusion: The present study revealed that P. major compared with theophylline, has a protective effect on lung in asthmatic rats.

  5. Lithium Attenuates TGF-β1-Induced Fibroblasts to Myofibroblasts Transition in Bronchial Fibroblasts Derived from Asthmatic Patients

    2012-01-01

    Full Text Available Bronchial asthma is a chronic disorder accompanied by phenotypic transitions of bronchial epithelial cells, smooth muscle cells, and fibroblasts. Human bronchial fibroblasts (HBFs derived from patients with diagnosed asthma display predestination towards TGF-β-induced phenotypic switches. Since the interference between TGF-β and GSK-3β signaling contributes to pathophysiology of chronic lung diseases, we investigated the effect of lithium, a nonspecific GSK-3β inhibitor, on TGF-β1-induced fibroblast to myofibroblast transition (FMT in HBF and found that the inhibition of GSK-3β attenuates TGF-β1-induced FMT in HBF populations derived from asthmatic but not healthy donors. Cytoplasmically sequestrated β-catenin, abundant in TGF-β1/LiCl-stimulated asthmatic HBFs, most likely interacts with and inhibits the nuclear accumulation and signal transduction of Smad proteins. These data indicate that the specific cellular context determines FMT-related responses of HBFs to factors interfering with the TGF-β signaling pathway. They may also provide a mechanistic explanation for epidemiological data revealing coincidental remission of asthmatic syndromes and their recurrence upon the discontinuation of lithium therapy in certain psychiatric diseases.

The purpose of the present study was to relationship bronchodilator response (BDR with oxygen pulse (OP and ventilatory threshold (VT in asthma children with various body compositions during progressive aerobic activities. Material and Methods: 25 obese children (BMI>25 and %fat>30with asthma(10 subjects, and healthy children (15 subjects  and 25 lean children(BMI<20 and %fat<20 with asthma(13 subjects, and healthy children (7 subjects performed an exercise protocol in a constant temperature environment 2 ± 22 ° C and humidity (5 ± 35%. During exercise, the steady-state levels of cardio-respiratory parameters were measured using gas analyzer (K4B2. Results: The results showed that after a progressive aerobic activity, values peak oxygen consumption(vo2peak ​​, bronchodilator(BDR, oxygen pulse(OP and ventilatory threshold(VT  in lean and obese asthmatic children were lower than in healthy lean and obese children. In addition, lean children with asthma had lower VT and higher VO2peak , OP and BDR values​​, as compared obese asthmatic children. Between BDR and VT in lean and obese asthmatic children an inverse relationship between BDR and OP and a direct link to asthma in obese children and obese asthmatic children, there was a negative relationship non-significant. Conclusion: Compared with lean children, asthma, obesity as an additional load will affect lung function and increase the pressure on childhood asthma. Therefore, we can accept that obesity may limit performance of exercise in childhood asthma.

    Full Text Available Com o objetivo de avaliar o desempenho do Programa de Atenção a Crianças Portadoras de "Chiado no Peito", no Município de Embu, São Paulo, foram estudadas 434 crianças e adolescentes de zero a 14 anos, admitidas no programa de maio/88 a julho/93. Mais de 90% desses pacientes nunca haviam sido acompanhados por esse motivo em serviço médico. Apenas 6,2% foram encaminhados a outros serviços de referência durante o acompanhamento no programa. Segundo critérios clínicos, os pacientes foram classificados em: bebê chiador (21,8%, asmáticos leves (41,7%, asmáticos moderados (28,3%, asmáticos graves (7,6% e outros (0,4%. Ao se analisar o comportamento dos asmáticos moderados e graves acompanhados por mais de um ano, observou-se melhora clínica nesses dois grupos, e o que influenciou positivamente esse fato foi a maior aderência ao uso da medicação. O número de exacerbações decresceu entre os asmáticos graves, após um ano de acompanhamento regular, embora durante os 12 meses analisados tenha havido um consumo praticamente constante de medicação broncodilatadora. O abandono ocorreu em 53,2% das crianças matriculadas, principalmente nos primeiros seis meses de acompanhamento, sendo significantemente mais freqüente entre os asmáticos moderados. Concluímos que as crianças com maior aderência ao programa se beneficiaram do mesmo, apesar das dificuldades e da falta de alguns recursos medicamentosos atualmente existentes.The main objective of this study was to evaluate the effectiveness of the Program Targeting Children with "Chest Wheezing" carried in the city of Embu, São Paulo.

    Airway tolerance is the usual outcome of inhalation of harmless antigens. Although T cell deletion and anergy are likely components of tolerogenic mechanisms in the lung, increasing evidence indicates that antigen-specific regulatory T cells (inducible Treg cells [iTreg cells]) that express Foxp3 are also critical. Several lung antigen-presenting cells have been suggested to contribute to tolerance, including alveolar macrophages (MØs), classical dendritic cells (DCs), and plasmacytoid DCs, but whether these possess the attributes required to directly promote the development of Foxp3(+) iTreg cells is unclear. Here, we show that lung-resident tissue MØs coexpress TGF-β and retinal dehydrogenases (RALDH1 and RALDH 2) under steady-state conditions and that their sampling of harmless airborne antigen and presentation to antigen-specific CD4 T cells resulted in the generation of Foxp3(+) Treg cells. Treg cell induction in this model depended on both TGF-β and retinoic acid. Transfer of the antigen-pulsed tissue MØs into the airways correspondingly prevented the development of asthmatic lung inflammation upon subsequent challenge with antigen. Moreover, exposure of lung tissue MØs to allergens suppressed their ability to generate iTreg cells coincident with blocking airway tolerance. Suppression of Treg cell generation required proteases and TLR-mediated signals. Therefore, lung-resident tissue MØs have regulatory functions, and strategies to target these cells might hold promise for prevention or treatment of allergic asthma.

    Full Text Available AIM AND OBJECTIVES Cross-sectional study to compare the peak expiratory flow rate with the help of “Mini-Wright” peak flow meter among females, normal healthy subjects and subjects who are asthmatics of age group 20–40 years. METHOD 60 adult females of age group 20-40 years (30-Healthy and 30-Asthmatics for whom baseline pulmonary function testing was done to differentiate normal and asthmatic. All cases were clinically examined to rule-out any obvious cardiopulmonary diseases. Subjects were provided one mini Wright’s peak expiratory flow meter, were individually trained for measuring their own PEFR in L/min and were instructed to record the readings with Wright’s portable peak flow meter at 5:00 am, 8:00 am, 11:00 am, 14:00 pm, 17:00 pm, 20:00 pm and 23:00 pm on two consecutive days. They were instructed to obtain at least three recordings at a time. RESULTS In healthy subjects it is observed that mean PEFR values at morning 5:00 hours was 276.966, which is the lowest value of day and 440.653 at evening 17:00 hour, which is the highest value of the day for this shows there is a progressive rise of about 59.1% in mean PEFR value from early morning till evening and at night 11:00 hours we got a mean value of 340.143, a decline of 22.809% when compared to peak value of the day (17:00 hours. In Asthmatic, early morning mean PEFR value at 5:00 hours was 157.888, which is lowest value of the day and 369.774 at evening at 17:00 hours, which is the highest mean PEFR value of the day. There is a significant rise of about 134.2002% in the mean PEFR value from early morning till evening and at night 11:00 hours we got a mean value of 197.666, a decline of 46.5441% when compared to peak value of the day (17:00 hours. CONCLUSION It is seen that though the circadian rhythm in asthmatics follows a similar pattern, i.e. PEFR dip in morning and PEFR peak in late afternoon, but the swing of PEFR from the mean value is more than in normal subjects.

    Full Text Available Background: Asthma constitutes the first disease among chronic diseases in children. The morbid-mortality promoted to continue being elevated in spite of the new therapies. For this reason it is a disease with high priority for investigation in pediatric ages. Method: A control and case group study was carried out. The samples was composed by 72 asthmatic children from three General Comprehensive doctor offices from Palmira health area located in Cienfuegos Province, Cuba; and a control group of 72 children apparently healthy from the same population. A questionnaire with the different risk variables was elaborated. Odds ratio technique was used to estimate the risk. Results: low weight at birth, family history of asthma, brochiolitis antecedent and the excessive usage of antibiotics in children under 1 year old were the main risks found. Conclusions: It is conclusive that the exposure to home allergen plus a genetic favorable factor, the prematurity, and brochiolitis constituted the most outstanding elements to suffer from asthma in the population studied.

    Full Text Available Abstract Background The Mexico City Metropolitan Area is densely populated, and toxic air pollutants are generated and concentrated at a higher rate because of its geographic characteristics. It is well known that exposure to particulate matter, especially to fine and ultra-fine particles, enhances the risk of cardio-respiratory diseases, especially in populations susceptible to oxidative stress. The aim of this study was to evaluate the effect of fine particles on the respiratory burst of circulating neutrophils from asthmatic patients living in Mexico City. Methods In total, 6 subjects diagnosed with mild asthma and 11 healthy volunteers were asked to participate. Neutrophils were isolated from peripheral venous blood and incubated with fine particles, and the generation of reactive oxygen species was recorded by chemiluminescence. We also measured plasma lipoperoxidation susceptibility and plasma myeloperoxidase and paraoxonase activities by spectrophotometry. Results Asthmatic patients showed significantly lower plasma paraoxonase activity, higher susceptibility to plasma lipoperoxidation and an increase in myeloperoxidase activity that differed significantly from the control group. In the presence of fine particles, neutrophils from asthmatic patients showed an increased tendency to generate reactive oxygen species after stimulation with fine particles (PM2.5. Conclusion These findings suggest that asthmatic patients have higher oxidation of plasmatic lipids due to reduced antioxidant defense. Furthermore, fine particles tended to increase the respiratory burst of blood human neutrophils from the asthmatic group. On the whole, increased myeloperoxidase activity and susceptibility to lipoperoxidation with a concomitant decrease in paraoxonase activity in asthmatic patients could favor lung infection and hence disrupt the control of asthmatic crises.
