Our findings support the hypothesis of a link between maternal depression and infant's wheezing and its severity early in life independent of allergic status. Consequences of our study include the need to assess depressive symptoms in mothers of infants with asthma.
Our study shows that symptoms of asthma, allergic rhinitis and eczema were stable, supporting the effectiveness of national asthma prevention and management guidelines for such diseases. The increase in indices related to lifetime diagnosis could be the result of increased public and professional awareness of the diseases and changes in diagnostic labelling in recent years.
Immediate allergic hypersensitivity reactions with fentanyl are rarely reported. We diagnosed a presumably IgE-mediated allergic hypersensitivity reaction comprising generalized erythema and bronchospasm 4 h after the first-time application of transdermal fentanyl. Prick test remained negative with fentanyl whereas an intradermal test (IDT) with fentanyl was positive (dilution 10(-2)). Cross-reactivity was found with sufentanil but not with remifentanil. The diagnosis was supported by the clinical history and a positive IDT with fentanyl. This case report confirms the need for a systematic allergological investigation in case of immediate hypersensitivity reactions for all drugs and all modes of administration.
Aim. We investigated the relationship between sex (genetic/biological) and gender (environmental/ cultural) factors in relation to adolescent tobacco smoking. Methods. A representative sample of 11,582 students from French secondary public schools participated in the study by completing a self-administered, standardised questionnaire. Results. Using the WHO classification for smoking in the youth, 15.6% of the adolescents were regular smokers, 7.7% occasional smokers, 17.9% experimental smokers and 4.8% ex-smokers, with no statistically significant gender difference. Taking non-smoking as a reference, puberty had a much greater effect on the likelihood of being a regular smoker [OR=18.0 (95% Confidence Interval: 9.6- 32)] than of being an experimental/occasional smoker [OR=3.7 (2.9-4.6)] among girls. For boys, the effect of puberty was not as great [OR=4.7 (3.5-6.5)] for regular vs. [OR=2.1 (1.8-2.5)] for experimental/occasional smokers). Similarly, illicit drug use had a larger effect on the likelihood of being regular smoker vs. non-smoker [OR=15.0 (12.0-20.0) in boys and 12 (8.8-16.0) in girls] than of being experimental/occasional smoker vs. a non-smoker [OR=4.8 (3.7-6.1) and 2.9 (2.1-3.9) respectively]. Other factors related to regular smoking were exposure to passive smoking and regular alcohol consumption. Living with both parents was a protective factor for life and regular smoking in both genders. Conclusions. Our results show that influential factors of sex-related (puberty), gender-specific (environmental tobacco smoking, alcohol consumption, drug abuse) or sex/gender (regular sexual intercourse) are related to the smoking behaviour in French adolescents.
Our data suggest that, besides well-known factors such as genetic background, direct mechanical effects, and reduced physical activity, abnormal eating behaviors and weight concerns might intervene in the relation between obesity and asthma. Psychosocial dimension has to be considered to disentangle the complex relation between obesity and asthma in adolescence in view of prevention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
