Upper age limit for bronchiolitis: 12 months or 6 months?

confidence in their ability to quit experiencing a reduction in their level of motivation, and smokers achieving success boosting them up. We could not establish with confidence whether motivation levels were still balanced between groups throughout the duration of the study. Lastly, it was suggested to expand upon the correlation between behavioural (i.e. GN-SBQ) and physical (i.e. the Fagerström Test for Nicotine Dependence (FTND)) dependence to clarify if they are independent of each other or correlated, in the assumption that a smoker highly dependent on nicotine would also tend to be more behaviourally dependent. In our study, the results of the logistic model analyses indicate that only the use of Paipo is an important predictor of success in smokers with high GN-SBQ score (OR 8.45), whereas FTND has no impact in the model. We also carried out additional analyses in the Paipo users (table 1); cross tabulation of quit rates at week 24 (intent-to-treat analysis) showed that in smokers with low GN-SBQ, chance of success was much higher in low FTND (16.7% success rate) compared to high FTND group (only 10.0% success rate). However, the numbers in some of the cells is so small that no sound conclusion can be reached about potentially important interactions between beha-vioural and physical dependence. Perhaps, as sensibly pinpointed by K. Fagerström, the main strength of this study is that it has the potential to open up a new line of research, in which improved characterisation of beha-vioural sub-phenotypes in smokers undergoing smoking cessation programmes can be exploited to advance current understanding of tobacco dependence and its management. Effect of a nicotine-free inhalator as part of a smoking-cessation programme. MIDULLA et al. [1] published their interesting results on virus-specific 1-yr outcome of infants with bronchiolitis requiring hospital treatment. Originally, 313 bronchiolitis patients aged ,12 months with no previous wheezing histories were recruited during a 5-yr period, excluding summer times. On admission, 195 viruses were detected in 174 (55.6%) infants by PCR from nasal wash samples. As the authors concluded, the virus detection rate was rather low [1]. When nasopharyngeal aspirates are studied and the available PCR panel covers all notable respiratory viruses, the rate can be nearly 100%, as was seen in our recent study in ,6-month-old infants with bronchiolitis [2]. 12 months later, 262 (83.7%) parents were contacted by telephone and interviewed using structured questionnaires, TABLE 1 Cross tabulation (intent-to-treat analysis at week 24) …
