ABSTRACT

OBJECTIVE@#To study the correlation between fractional exhaled nitric oxide (FeNO) and airway reversibility in children with IgE-mediated asthma.@*METHODS@#A total of 86 children, aged 6-14 years, who were initially diagnosed with acute attack of asthma from September 2016 to August 2018 were enrolled as subjects. According to the results of serum specific IgE, they were divided into IgE mediated group with 61 children and non-IgE mediated group with 25 children. According to the results of allergen detection, the IgE mediated group was further divided into four groups with one, two, three, and four or more positive allergens. FeNO and the parameters of pulmonary ventilation function before and after dilation test were measured. Pearson correlation analysis was used to evaluate the correlation of FeNO with each parameter of pulmonary function.@*RESULTS@#The IgE mediated group had significantly higher FeNO than the non-IgE mediated group (P0.05). In the non-IgE mediated group, FeNO level was not correlated with the above indicators (P>0.05).@*CONCLUSIONS@#FeNO level is associated with the degree of allergies. For children with IgE-mediated asthma, FeNO is positively correlated with airway reversibility, which has a certain value in the diagnosis of asthma, disease evaluation, and understanding of airway reversibility. For children with non-IgE-mediated asthma, FeNO cannot be used to evaluate airway reversibility. These two types of asthma should be treated differently.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the prevalence, current treatment, and clinical characteristics of asthma, as well as the risk factors for this disease, among children aged 0-14 years in 2010 in urban Zhongshan, China.</p><p><b>METHODS</b>A total of 10 336 children aged 0-14 years were selected from urban Zhongshan by cluster random sampling. The Third National Childhood Asthma Epidemiological Questionnaire 2010 was used to analyze the prevalence, current treatment, and clinical characteristics of childhood asthma, as well as the risk factors for this disease.</p><p><b>RESULTS</b>Asthma was diagnosed in 179 cases (1.73%). The prevalence of asthma in male children was significantly higher than that in female children (2.25% vs 1.16%; P<0.01). Of the 179 patients, severe attacks were common in 104 cases (58.1%), 110 cases (61.5%) had slow onset, 102 cases (57.0%) had gradually relieved conditions, 61 cases (34.1%) suffered from asthma during seasonal transition, and 150 cases (83.8%) developed asthma due to respiratory tract infection. Among all asthmatic children, 71.5% had been treated with inhaled corticosteroids, and 71.5% had been treated with bronchodilator. The multivariate logistic regression analysis showed that a history of penicillin allergy, a family history of allergy, food allergy, eczema, allergic rhinitis, cesarean delivery, family mould, and perinatal passive smoking were independent risk factors for childhood asthma.</p><p><b>CONCLUSIONS</b>The prevalence of childhood asthma in urban Zhongshan is on a high level, and is associated with gender. The treatment of asthma has been standardized, but still needs further improvement. The onset of asthma attack is influenced by various factors.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the incidence of wheezing and chronic cough in children aged 3-14 years in different living areas of Zhongshan, China.</p><p><b>METHODS</b>According to the unified program of the 2010 national epidemiological survey of asthmatic children aged 0-14 years, a questionnaire survey of the children aged 3-14 years in rural and urban areas of Zhongshan was conducted.</p><p><b>RESULTS</b>A total of 15 763 children were included in the survey. Among all participants, 8 248 were from the urban area, and 7 515 from the rual area; 8 306 were boys, and 7 457 were girls. The percentage of children with a history of wheezing was significantly higher in the urban group than in the rural group (6.6% vs 3.2%; P<0.05), and it was significantly higher in boys than in girls for each group (P<0.05). The urban group had a significantly higher percentage of individuals who had wheezing in the past one year than the rural group (2.8% vs 1.5%; P<0.05), and this percentage was significantly higher in boys than in girls for each group (P<0.05). Compared with the rural group, the urban group had a significantly higher percentage of individuals who had chronic cough (duration 1 year) (7.9% vs 3.1%; P<0.05). The above indices were relatively high in children under 6 years of age, and all but the percentage of girls who had wheezing in the past one year in both rural and urban areas showed significant differences between all age groups.</p><p><b>CONCLUSIONS</b>The incidence of wheezing and chronic cough varies with age, sex, and living area for children aged 3-14 years in Zhongshan, and it is relatively high under 6 years of age, in the urban area, and among boys.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the causes of unintentional injuries in children and to provide reference for reducing the incidence of unintentional injuries in children.</p><p><b>METHODS</b>A retrospective analysis was performed on the clinical data of 924 children with unintentional injuries who were hospitalized in Zhongshan Boai Hospital from January 2008 to December 2010.</p><p><b>RESULTS</b>Of the 924 cases, 26.4% suffered falls, which was the most common cause of injuries, 15.7% suffered burns and scalds, 14.0% were injured by foreign bodies, and 13.1% were injured in traffic accidents. Unintentional injuries occurred mainly among children aged 0-3 years (67%). The proportion of cases in summer (July to September) was significantly higher than in any other season (P < 0.05), and burns were the common causes of injuries in summer. Home was the most common place where unintentional injuries occurred (36.9%). The incidence of traffic accidents was significantly higher in non-local children than in local children (P < 0.001). As for the parents' educational levels, the children whose parents had an education level below junior middle school accounted for the highest proportion of all cases of unintentional injury (45.5%). Injuried cases in rural areas accounted for a significantly higher percentage than in urban areas (P < 0.05).</p><p><b>CONCLUSIONS</b>Falls are the principal cause of unintentional injuries in children. Young children (0-3 years) are most vulnerable to unintentional injuries. Unintentional injuries mostly occur at home. The incidence of traffic accidents is higher in non-local children than in local children. Parents' education levels are associated with the incidence of unintentional injuries. In order to reduce the incidence of unintentional injuries in children, preventive measures must be carried out, and safety education should be enhanced in consideration of children's age, sex and family background.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the roles of the residential environment and eating habits in the pathogenesis of bronchial asthma in school children.</p><p><b>METHODS</b>One hundred and twenty-nine children between 6-12 years who were diagnosed with asthma were enrolled. Two hundred and fifty-eight healthy age- and gender-matched children were used as the control group. A questionaire which included 23 factors related to respiratory tract anaphylactic diseases such as residential environment and eating habits were completed by the children's parents.</p><p><b>RESULTS</b>Logistic regression analysis showed that 6 variances out of 16 agents of the residential environment, the experience of raising pets, the type of floor, the type of pillow, the type of quilts, the heating equipments and the house area, were entered into the regression equation; none of the 7 variances of eating inhabits was entered into it.</p><p><b>CONCLUSIONS</b>The residential environment plays an impotent role in the pathogenesis of bronchial asthma in children. The incidence of bronchial asthma in children can be reduced by the improvement of the residential environment.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study changes of plasma motilin concentration and it's effect on enteral nutrition in premature infants.</p><p><b>METHODS</b>The plasma motilin concentration of 72 premature infants was measured within 12 hours after birth before enteral feeding and on day 3 and 7 of life by using radioimmunoassay. Sixteen full-term neonates were enrolled as controls.</p><p><b>RESULTS</b>(1) The plasma concentrations of motilin in premature infants before enteral feeding after birth and on day 3 and 7 were 198.65 +/- 58.42 ng/L, 248.83 +/- 56.00 ng/L, and 376.77 +/- 139.46 ng/L, respectively, which were significantly lower than those in the control group (300.33 +/- 67.15 ng/L, 334.26 +/- 83.81 ng/L, 510.64 +/- 179.85 ng/L) (P < 0.001 or < 0.01). There was positive correlation between the concentration and gestational age, age in day and the volume of milk. On day 7 the level of motilin was higher than the pre-enteral feeding level of the full term control group. (2) The plasma motilin concentration in feeding un-tolerated premature infants group was lower than that in the normal group, especially on day 3 of life (P < 0.05). (3) Early enteral feeding could improve the plasma motilin levels, gastrointestinal motility and nutrition tolerance in premature infants.</p><p><b>CONCLUSIONS</b>The gastrointestinal functions of premature infants are adaptable to enteral nutrition. Early enteral feeding (including minimal enteral nutrition and non-nutritive sucking) can promote adaptive rapid growth and development of intestine.</p>
