Atopy and house dust mite sensitization as risk factors for asthma in children
No full textRecent evidence suggests that asthma is not invariably related to atopy. The aim of this study was to evaluate the frequency of atopy, asthma and sensitization to eight common allergens in a large group of children with allergic symptoms.
METHODS:
1426 children referred to our Paediatric Asthma and Allergy Center because of allergic symptoms were examined. Bronchial asthma, allergic rhino-conjunctivitis, food allergy and atopic dermatitis were diagnosed with standardized methods. Atopy was diagnosed if at least one skin test was positive.
RESULTS:
Of the 1426 children examined, 629 (44%) were atopic and 769 (56%) were non-atopic. Asthma was diagnosed in the same proportion (i.e., 64%) of atopic and non-atopic children. However, after division into age groups, non-atopic asthma was significantly more prevalent (chi2 = 8.46) in children between 0 and 3 years old (group 1). On the other hand, atopy was significantly associated with asthma only in group 3 (odds ratio 1.85). Furthermore, a significant association with asthma symptoms was found for house dust mite (HDM) in group 3 (odds ratio 4.8).
CONCLUSIONS:
Asthma is related to atopy in pre-selected children only from the age of 7 years. House dust mite sensitization seems to be an important determinant of asthma in these "older" children
Remnants and Revenants: politics and violence in the work of Agamben and Derrida
No full textThis is the peer reviewed version of the following article: Frazer, Elizabeth, and Kimberly Hutchings. "Remnants and revenants: politics and violence in the work of Agamben and Derrida." The British Journal of Politics & International Relations 13.2 (2011): 127-144, which has been published in final form at http://dx.doi.org/10.1111/j.1467-856X.2010.00428.x. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.Jacques Derrida and Giorgio Agamben both consider the question of whether there can be politics without violence, offering contrasting responses. In the case of Agamben, the remnant (that which remains) is disruptive and destabilising of present institutions; in the case of Derrida the revenant, the spectre, promises a future that is open. This reading of the two theories suggests that Derrida's response to the question of politics and violence is more persuasive than Agamben's. But the abstraction of his argument, like the tensions and contradictions in Agamben's, means that we are not hereby furnished with the resources to think politically about violence

Brisures du romaneque: 'La Malédiction de la Madone', ou d'une pratique ironique du docufiction.
No full textLa Malédiction de la Madone, pubblicato nel 2022, è il primo romanzo in cui Philippe Vilain, scrittore tra i maggiori rappresentanti dell’autofinzione, ab- bandona la narrazione in prima persona per un “docufiction” in terza persona basato sulla vita della camorrista Pupetta Maresca. questo cambio di rotta, an- cor più sorprendente per un autore come Vilain che aveva sempre vilipeso que- sto genere letterario, è occasione di mettere in questione le sue concezioni del romanzo e della letteratura. Ne vien fuori una narrazione tesa tra l’aspirazione a far corpo unico con la sua precedente produzione letteraria e le condizioni im- poste dalla “docufinzionalizzazione” della storia. La Malédiction de la Madone diventa così un vero e proprio laboratorio letterario dove la sperimentazione più fine e pensosa svela inattese punte d’ironia.La Malédiction de la Madone, published in 2022, is the first novel in which Philippe Vilain, a writer among the greatest representatives of autofiction, abandons the first-person narration for a third-person “docufiction” based on the life of the camorrist Pupetta Maresca. This change of course, even more surprising for an author like Vilain who had always vilified this literary genre, is an opportunity to question his conceptions of the novel and of literature. The result is a narrative tended between the aspiration to merge with his previous literary pro- duction and the conditions imposed by “docufictionalization” of the history. The Malédiction de la Madone thus becomes a real literary laboratory where the finest and most thoughtful experimentation reveals unexpected hints of irony
Fractional exhaled nitric oxide (FENO), lung function and airway hyperresponsiveness in naïve atopic asthmatic children.
No full textBackground. Measurement of fractional exhaled nitric oxide (FENO) is a noninvasive,simple, well-tolerated, and reproducible marker of airway inflammation. Asthmatic children with normal respiratory function could be affected by airway inflammation.
The aim of this study was to assess the correlation between FENO and bronchial hyperesponsivenes(Bs HR) to methacholine and between FENO and lung function in atopic children with intermittent asthma. Methods. Thirty-seven children (21 male), aged 7.2-14.4 years (median: 10.9 years), suffering from mild intermittent atopic
asthma with a physician-diagnosed history of wheezing and/or chest tightness were studied. None had taken anti-asthmatic therapy for at least three months before the study. No child had symptoms of respiratory tract infection in the month before the study. All subjects underwent FENO measurement, pulmonary function testing and
the methacholine provocation tests.
Results. The mean percentages of FEVI and FEF25-75 were 91.9+10.5 and 88.3+11.8, respectively.The mean FENO was 62.2+39.2 ppb and PC20 methacholine was 0.93 mg/ml+0.54. Significant correlations were identified between FENO and FEVI (p<0.0059, r=0.468) and between FENO and FEF25-75 (p<0.0098, r=0.439). There was no correlation between FENO and log PC20 (p=0.14).
Conclusions. A single FENO measurement is probably of scarce prognostic and predictive value and it is not surprising to find discordance with BHR. We suggest that FENO measurement could represent a good marker of airway inflammation also in naive atopic children with intermittent asthma. Repeated measurements over time are probably necessary to understand better the clinical implications of the data obtained in this study
FP-INJECTIVE SEMIRINGS, SEMIGROUP RINGS AND LEAVITT PATH ALGEBRAS
No full textIn this paper we give characterisations of FP-injective semirings (previously termed “exact” semirings in work of the first author). We provide a basic connection between FP-injective semirings and P-injective semirings, and establish that FP-injectivity of semirings is a Morita invariant property. We show that the analogue of the Faith-Menal conjecture (relating FP-injectivity and self-injectivity for rings satisfying certain chain conditions) does not hold for semirings. We prove that the semigroup ring of a locally finite inverse monoid over an FP-injective ring is FP-injective and give a criterion for the Leavitt path algebra of a finite graph to be FP-injective
