RESUMEN
BACKGROUND: Preterm infants, particularly those with bronchopulmonary dysplasia (BPD), are at risk of lung development problems. Over the last decades, lung protective strategies have been used, decreasing the risk of chronic lung disease. OBJECTIVE: To evaluate the pulmonary function test (PFT) of preterm infants born after the introduction of lung protective strategies and to assess perinatal determinants of impaired lung function in this population. METHODS: A prospective, observational, single-center study was conducted in the neonatal unit of a high-complexity hospital. The study included newborns with less than 32 weeks gestational age born between 2012 and 2014, who were followed up until they reach school age. For the main outcome, two groups were stablished: no BPD or grade 1 BPD (no BPD/1) and grade 2 or 3 BPD (BPD 2/3). RESULTS: Out of 327 patients, 116 were included. BPD was diagnosed in 49.1% (47), with 50.9% (29) classified as grade 1, 35.1% (20) as grade 2, and 14.0% (8) as grade 3. Mean age at PFT was 8.59 years (SD 0.90). Mean FEV1% was 95.36% (SD 13.21) and FEV1 z-score -0.36 (SD 1.12); FVC% 97.53% (SD 12.59) and FVC z-score -0.20 (SD 1.06); FEV1/FVC ratio 85.84% (SD 8.34) and z-score -0.24 (SD 1.34). When comparing patients with no BPD/1 and BPD 2/3, we observed differences in all pulmonary function parameters, which persisted after adjusting for gestational age. No differences in PFT were observed between patients without BPD and those with grade 1 BPD. Most patients (76.7%, 89) had normal spirometry pattern, with obstructive pattern observed in 12.9% (15), restrictive pattern in 9.5% (11), and mixed pattern in 0.9% (1) of patients. CONCLUSION: Preterm infants with BPD 2/3 showed a decrease in all pulmonary function parameters compared to preterm infants with no BPD/1; an effect that was independent of gestational age. Among patients with BPD who had an altered PFT pattern, the most common pattern was obstructive, followed by restrictive and then, mixed.
RESUMEN
BACKGROUND: Children's diffuse lung disease, also known as children's Interstitial Lung Diseases (chILD), are a heterogeneous group of rare diseases with relevant morbidity and mortality, which diagnosis and classification are very complex. Epidemiological data are scarce. The aim of this study was to analyse incidence and prevalence of chILD in Spain. METHODS: Multicentre observational prospective study in patients from 0 to 18 years of age with chILD to analyse its incidence and prevalence in Spain, based on data reported in 2018 and 2019. RESULTS: A total of 381 cases with chILD were notified from 51 paediatric pulmonology units all over Spain, covering the 91.7% of the paediatric population. The average incidence of chILD was 8.18 (CI 95% 6.28-10.48) new cases/million of children per year. The average prevalence of chILD was 46.53 (CI 95% 41.81-51.62) cases/million of children. The age group with the highest prevalence were children under 1 year of age. Different types of disorders were seen in children 2-18 years of age compared with children 0-2 years of age. Most frequent cases were: primary pulmonary interstitial glycogenosis in neonates (17/65), neuroendocrine cell hyperplasia of infancy in infants from 1 to 12 months (44/144), idiopathic pulmonary haemosiderosis in children from 1 to 5 years old (13/74), hypersensitivity pneumonitis in children from 5 to 10 years old (9/51), and scleroderma in older than 10 years old (8/47). CONCLUSIONS: We found a higher incidence and prevalence of chILD than previously described probably due to greater understanding and increased clinician awareness of these rare diseases.
RESUMEN
OBJECTIVES: Health educational interventions improve health outcomes and quality of life in children with asthma. The main purpose of this study was to evaluate the effect of an education intervention for an asthma inhaler technique during hospital admission for an asthma exacerbation. METHODS: This prospective study was conducted in a pediatric hospitalization unit of a third-level hospital. Children admitted for an asthma exacerbation were eligible for inclusion. It was developed in 2 phases: during hospital admission (T1) and 1 month after discharge (T2). In the T1 phase, caregivers completed the questionnaire to assess asthma control in children (CAN questionnaire) and performed the inhaler technique, which was evaluated with a 6-step checklist. An educational intervention was performed. In the T2 phase, caregivers completed the CAN questionnaire, and the inhaler technique was reevaluated. We hypothesized that the inhaler technique improved after the implementation of an asthma education program. RESULTS: A total of 101 children were included, of whom 85 completed the T2 phase (84%). At baseline, 11.8% of participants performed the inhaler technique correctly. All steps of the inhaler technique upgraded in the T2 phase significantly (P < .01), except for the step "assemble the inhaler device correctly." Former evaluation by a pediatric pneumologist was associated with a higher score in the inhaler technique in the T1 phase. The median CAN questionnaire score in the T1 phase was 8 (interquartile range 4-16), which reduced to 4 (interquartile range 1.2-6) in the T2 phase (P < .01). CONCLUSIONS: The development of an educational intervention during admission improved inhaler technique as well as asthma knowledge.

OBJECTIVE: To describe the epidemiological characteristics, hospital follow-up, and course of patients who underwent surgery for esophageal atresia and its consequences on lung function. POPULATION AND METHODS: Retrospective, longitudinal, and analytical study. The medical records of patients with esophageal atresia born between 1996 and 2017 were reviewed. Perinatal data, type of atresia, associated malformations, respiratory and gastrointestinal complications, and spirometry data were recorded over 3 years. RESULTS: A total of 97 patients were included. The most common type of atresia was III, and the most frequent syndrome, trisomy 21; 13.4 % of patients died in the neonatal period; 23.8 % were followed up by the Department of Pulmonology, and their respiratory complications included exacerbations (46.4 %), wheezing or asthma (36 %), and pneumonia (26.8 %). Gastroesophageal reflux was a risk factor for wheezing (OR: 5.31; p = 0.002), exacerbations (OR: 4.00; p=0.009), and pneumonia (OR: 3.24; p = 0.02). In the first spirometry (n=20), the pattern was normal in 65 %; restrictive in 30 %; and mixed in 5 %. In the second spirometry (n = 19), the pattern was normal in 42.1 %; restrictive in 31.6 %; obstructive in 15.8 %, and mixed in 10.5 %. In the third spirometry (n = 14), the pattern was normal in 50 %; restrictive in 21.4 %; obstructive in 14.3 %, and mixed in 14.3 %. CONCLUSIONS: In our sample of patients, a large proportion had respiratory and gastrointestinal comorbidities. Lung function worsened progressively.
Objetivo: Describir las características epidemiológicas, el seguimiento hospitalario y la evolución de los pacientes intervenidos por atresia esofágica y su repercusión en la función pulmonar. Población y métodos: Estudio retrospectivo, longitudinal y analítico. Se revisaron las historias clínicas de pacientes con atresia esofágica nacidos entre 1996 y 2017. Se registraron datos perinatales, tipo de atresia, malformaciones asociadas, complicaciones respiratorias y digestivas, y los datos espirométricos durante tres años. Resultados: Se incluyeron 97 pacientes. El tipo de atresia más frecuente fue el III y el síndrome más frecuente, la trisomía 21. El 13,4 % fallecieron en el período neonatal. El 23,8 % de los pacientes estuvo en seguimiento por Neumología y presentó como complicaciones respiratorias exacerbaciones (el 46,4 %), sibilancias o asma (el 36 %), neumonías (el 26,8 %). El reflujo gastroesofágico fue factor de riesgo de sibilancias (OR 5,31; p = 0,002), exacerbaciones (OR 4,00; p = 0,009) y neumonías (OR 3,24; p = 0,02). En la primera espirometría (n = 20), un 65 % presentaba patrón normal; un 30 %, restrictivo, y un 5 %, mixto. En la segunda espirometría (n = 19), un 42,1 % presentaba patrón normal; un 31,6 %, restrictivo; un 15,8 %, obstructivo, y un 10,5 %, mixto. En la tercera espirometría (n = 14), el 50 % presentaba un patrón espirométrico normal; el 21,4 %, restrictivo; el 14,3 %, obstructivo, y un 14,3 %, mixto. Conclusiones: En nuestra muestra de pacientes, una importante proporción presentó comorbilidades respiratorias y digestivas. La función pulmonar empeoró progresivamente.
