Criteria heterogeneity in the diagnosis of acute bronchiolitis in Spain.

Introduction: Acute viral bronchiolitis (AB) is one of the most common respiratory diseases in infants. However, diagnostic criteria for AB are heterogeneous and not very well known.

Objective: To identify the diagnostic criteria for AB used by experts and clinical paediatricians in Spain.

Looking beyond patients: Can parents' quality of life predict asthma control in children?

Background: Social and family factors may influence the probability of achieving asthma control in children. Parents' quality of life has been insufficiently explored as a predictive factor linked to the probability of achieving disease control in asthmatic children.

Objective: Determine whether the parents' quality of life predicts medium-term asthma control in children.

Association between quality of life in parents and components of asthma control in children.

Objective: Describe the association between parents' quality of life and the two components of asthma control in children: impairment and risk.

Methods: Cross-sectional study with children between 4 and 14 years of age with active asthma recruited at primary care centers in Spain. Asthma control was assessed according to the Third National Asthma Expert Panel Report, classifying "impairment" in three levels (well-controlled asthma, partially controlled, and poorly controlled), and "risk" as high or low.

Wheezing phenotypes in young children: an historical cohort study.

Background: Wheezing phenotypes in young children have usually been described on the basis of questionnaire surveys instead of prospectively doctor-diagnosed episodes, and have never been described in terms of incidence rates.

Aims: To identify wheezing phenotypes in the first three years and describe their incidence trends, and to investigate their relationship with asthma at six years of age.

Methods: Doctor-diagnosed wheezing episodes in the first 36 months and active asthma at six years were identified in a historical cohort of 3,739 children followed from birth in 29 primary care health centres in Spain.

Early patterns of wheezing in asthmatic and nonasthmatic children.

The aim of this study was to describe the time patterns of wheezing in both asthmatic and nonasthmatic children during the first 36 months of life, and to determine whether there are asthma-related breakpoints in the incidence of wheezing. Data from a historical cohort of children followed from birth to 6 years (SLAM cohort) were used. Wheezing episodes until 36 months and asthma at 6 years were both recorded by a doctor.
