Adherence to follow-up recommendations in asthma

A cross-sectional study showed that 130 out of 1758 (8%) primary school children without a previous asthma diagnosis had undiagnosed asthma. Thirty-eight per cent of their parents refused to visit a general practitioner for this disorder. Factors associated with the refusal were high maternal education, mild symptoms and absence of airway reversibility

Quality of life in children with undiagnosed and diagnosed asthma

This study describes the impact of undiagnosed and diagnosed asthma on quality of life in schoolchildren aged 7-10 years and their caregivers in a cross-sectional community-based study. Diagnosed asthma was defined as the parents' confirmation of a physician's diagnosis of asthma. Undiagnosed asthma was defined by asthma symptoms combined with airway reversibility or bronchial hyperresponsiveness. Quality of life was evaluated in all children with asthma and a sample of healthy controls by the Pediatric Asthma Quality of Life Questionnaire, and by the Paediatric Asthma Caregiver's Quality of Life Questionnaire. We studied the impact of breathing problems on school absence. Compared with healthy controls, quality of life scores among children and their caregivers were lower if the child had asthma (P < 0.05), with lowest scores in diagnosed asthma (P < 0.05 compared with undiagnosed asthma). Children with asthma reported more school absence (P < 0.05), with highest absence rate in those with diagnosed asthma. In conclusion, both undiagnosed and diagnosed asthma have a significant impact on the quality of life of both children and their caregivers

Pseudomonas aeruginosa diversity in distinct paediatric patient groups

ABSTRACTPseudomonas aeruginosa is a pathogen that often infects patients who are either immunocompromised or have local defects in host defences. It is known that cystic fibrosis (CF) patients are sometimes infected with certain clonal isolates. It is not clear whether these clonal isolates also infect non-CF patients and whether clonality of isolates occurs in other patient groups. The aim of this study was to investigate P. aeruginosa diversity and the occurrence of clones within five distinct paediatric patient groups susceptible to P. aeruginosa infection. P. aeruginosa isolates were cultured from 157 patients (CF first infection (CF-1 group) (29); CF chronic infection (CF-chronic group) (27); urinary tract infection (34); chronic suppurative otitis media (43); and intensive-care hospitalization/immunodeficiency (24)). All 202 phenotypically different isolates were tested for antimicrobial resistance and further typed by pulsed-field gel electrophoresis. Simpson's diversity index was calculated for the five groups. CF-chronic patients carried the highest number of distinct P. aeruginosa phenotypes and genotypes per culture. Isolates from the CF-chronic group were significantly less diverse than those from the other groups. A group of clonal isolates was observed among patients from the CF-chronic and CF-1 groups. These or different clonal isolates were not encountered among the three other patient groups. No characteristic resistance pattern could be identified among isolates from the distinct patient groups and among the clonal isolates. In conclusion, isolates of the CF-chronic group were less diverse than those in the other patient groups with P. aeruginosa infection; clonal isolates were not encountered in non-CF patients. Transmission of clonal CF isolates to other patient groups was not observed
