Resources to handle childhood asthma in Spain: The role of plans and guides and the participation of nurses.

BACKGROUND: Describe the assistance provided to asthmatic patients by Primary Care Paediatricians (PCP) in Spain and the material and human resources available for diagnosis and follow-up. METHODS: A cross-sectional descriptive study using an on-line survey, sent to PCP regarding the availability of diagnostic resources, carrying out programmed and educational activities, collaboration of nursing staff and their relationship with existing institutional plans to care for children with asthma. A latent class model (LCM) was used to describe the differences among paediatricians based on the variables studied. RESULTS: Of the 708 answers, 675 were considered valid; 76% of the paediatricians had a spirometer, 75% specific IgE, 17% prick-test, 95% had placebo inhalers and 97% inhalation chambers. 57% performed programmed activities with their patients, while 56% shared their care of asthmatic patients with their nursing staff, but only 25% of the nurses were involved in the follow-up and 12% in education. LCM identified four patterns. The two groups with greater access to diagnostic resources counted on institutional plans/guidelines. However, the only variable differentiating the groups with more programmed and educational activities was the participation of nurses. CONCLUSIONS: The availability of asthma plans/guidelines and resources for diagnosis and follow-up is not sufficient to improve important aspects of primary care for children with asthma. Organisational changes are necessary to include programmed asthma-related visits and paediatric teams with greater involvement of the nurses when caring for these patients.

[Therapeutic education in asthma management]. / La educación terapéutica en el asma.

All guidelines, protocols and recommendations underline the importance of therapeutic education as a key element in asthma management and control. Considerable evidence supports the efficacy and effectiveness of this measure. Health personnel, as well as patients and their parents, can and should be educated with two main objectives: to achieve the best possible quality of life and to allow self control of the disease. These goals can be attained through an educational process that should be individually tailored, continuous, progressive, dynamic, and sequential. The process poses more than a few difficulties involving patients, health professionals, and the health systems. Knowledge of the various psychological factors that can be present in asthmatic patients, as well as the factors related to the highly prevalent phenomenon of non-adherence, is essential. Awareness of the factors influencing physician-patient-family communication is also highly important to achieve the objectives set in therapeutic education. The educational process helps knowledge and abilities to be acquired and allows attitudes and beliefs to be modified. Patients and caregivers should be provided with an individual written action plan based on symptoms and/or forced expiratory volume in 1 second. Periodic follow-up visits are also required.

[Guidelines for the follow up of patients with bronchopulmonary dysplasia]. / Protocolo de seguimiento de los pacientes con displasia broncopulmonar.

Bronchopulmonary dysplasia (BPD) is the most common complication of preterm birth, and remains a major problem in pediatric pulmonology units. The decision of discharging from the Neonatal Unit should be based on a thorough assessment of the condition of the patient and compliance with certain requirements, including respiratory and nutritional stability, and caregiver education on disease management. For proper control of the disease, a schedule of visits and complementary tests should be established prior to discharge, and guidelines for prevention of exacerbations and appropriate treatment should be applied. In this paper, the Working Group in Perinatal Respiratory Diseases of the Spanish Society of Pediatric Pulmonology proposes a protocol to serve as a reference for the follow up of patients with BPD among different centers and health care settings. Key factors to consider when planning discharge from the Neonatal Unit and during follow up are reviewed. Recommendations on treatment and prevention of complications are then discussed. The final section of this guide aims to provide a specific schedule for follow-up and diagnostic interventions to be performed in patients with BPD.

[Analysis of puberal development and influence of weight loss in obese adolescent girls]. / Análisis e influencia de la pérdida de peso en el desarrollo puberal de adolescentes obesas.

OBJECTIVES: To study several aspects of puberal development in obese adolescent girls, and the influence of weight loss on these aspects. METHODS: A longitudinal retrospective study was performed of a sample of 26 adolescent girls with normal weight and 46 obese adolescent girls at the onset of puberty. The obese teenagers were further divided into two groups (normal and obese) according to their body mass index (BMI) at the end of puberty. Height, chronological and bone age, and growth velocity were evaluated in both groups. RESULTS: Of the teenagers who were obese at the onset of puberty, 63 % remained obese at the end of puberty. The obese teenagers were significantly taller than non-obese teenagers at the onset of puberty (143.2 +/- 6.96 vs 138.9 +/- 5.95 cm, respectively; p < 0.01). However, there were no differences between the two groups in final height. No differences were found between obese teenagers who lost weight and those who did not. There were no differences in chronological or bone age throughout puberal development in any of the groups. The mean growth velocity during puberty was significantly lower in obese teenagers than in non-obese teenagers (6.18 +/- 1.94 and 6.90 +/- 127 cm/year, respectively; p < 0.02). However, there were no differences between obese teenagers who lost weight and those who did not. CONCLUSIONS: Height gain in obese girls is greater in childhood but lower in adolescence. Final height is similar in both groups. Chronological age at the onset and end of puberty and bone maturation are similar in both groups. Weight loss during puberty does not modify growth pattern during this period of development.

[Exhaled nitric oxide in healthy and asthmatic children]. / Oxido nítrico exhalado en niños sanos y asmáticos.

OBJECTIVES: One of the main findings in asthma is chronic inflammation of the airway. Exhaled nitric oxide may be a useful marker of airway inflammation in asthmatic children. To evaluate the concentration of nitric oxide (NO) in exhaled air in healthy and asthmatic children and to relate this variable with different treatments. MATERIAL AND METHODS: A cross-sectional study was performed in a tertiary hospital. The concentration of exhaled NO (in parts per billion) was analyzed by chemoluminescence using the T technique of exhaling against expiratory resistance with positive mouthpiece pressure in two different study groups: group A (control group) consisted of 105 healthy children aged 6-14 years old without a history of respiratory disease; group B (asthmatic group) consisted of 79 children aged 6-14 years old diagnosed with asthma and undergoing anti-asthmatic treatment for at least the previous two months, depending on the severity of their disease. Quantitative variables were analyzed using Student's t-test and the relationship between qualitative variables was analyzed using the chi-squared test. RESULTS: Expired NO concentrations were significantly higher in the asthma group (15.02 ppb) than in the control group (5.40 ppb) (p < 0.01). No significant differences were found among the asthmatic children in asthma severity. Expired NO was higher in asthmatic children treated with nedocromil (16.62 ppb) than in those treated with inhaled corticosteroids (11.8 ppb) but this difference was not significant (p 0.08). Children who presented signs of acute asthma (22.87 ppb) and those with a positive bronchial dilatation test (20.65) showed higher expired NO values (p < 0.05) than those without asthmatic crises and/or a negative bronchial dilatation test. Likewise, children with atopic dermatitis showed higher expired NO concentrations (23.07 ppb) than those without atopic dermatitis (11.68 ppb) (p < 0.001). CONCLUSIONS: Children with asthma of various degrees of severity have higher levels of expired NO than do healthy children. Measurement of expired NO concentrations can be used to monitor bronchial inflammation and to evaluate the efficacy of anti-inflammatory treatments.

[Eosinophil cationic protein in the asthmatic infant: correlation with the clinic and pulmonary function]. / Proteína catiónica del eosinófilo en el asma infantil. Correlación con la clínica y función pulmonar.

PATIENTS AND METHODS: Serum eosinophil cationic protein (ECP) was measured in 99 chronic asthmatic patients (51 males and 48 females) with a mean age of 10.59 years and correlated with the number of eosinophils, lung function, symptoms in the last 6 months and clinical scoring (that reflecting the clinical situation during the last 15 days). RESULTS: Serum ECP showed a significant correlation with the total number of eosinophils (p < 0.001, R = 0.44), clinical scoring (p < 0.05, R = 0.26), number of inhaled beta 2-agonist doses needed in the last 15 days (p < 0.05, R = 0.26), forced expiratory volume during 1 second (FEV1; p < 0.01, R = -0.27), forced vital capacity (FVC; p < 0.05, R = -0.23), maximal mid-expiratory flow (FEF25-27; p < 0.001, R = -0.37). However, there was no significant correlation between the total number of eosinophils and the clinical situation of the children or the FEV1, but we found a significant correlation with the FEF25-27. Patients with ECP < 20 had better results on lung function tests than patients with ECP > 20 (FEV1: 108.89 +/- 17.7 vs 100.5 +/- 22 (p < 0.05), FEF25-27: 93.81 +/- 24.4 vs 75.21 +/- 24.5 (p < 0.001). CONCLUSIONS: The findings of this study suggest that the ECP level is a good marker of the situation of asthma in childhood. The levels of ECP will probably be able to help us to evaluate the degree of bronchial inflammation that neither the clinical state nor the lung function define completely.
