Anaphylaxis in Elderly Patients-Data From the European Anaphylaxis Registry

Background: Elicitors and symptoms of anaphylaxis are age dependent. However, little is known about typical features of anaphylaxis in patients aged 65 years or more. Methods: The data from the Network for Online Registration of Anaphylaxis (NORA) considering patients aged ≥65 (elderly) in comparison to data from adults (18–64 years) regarding elicitors, symptoms, comorbidities, and treatment measures were analyzed. Results: We identified 1,123 elderly anaphylactic patients. Insect venoms were the most frequent elicitor in this group (p < 0.001), followed by drugs like analgesics and antibiotics. Food allergens elicited less frequently anaphylaxis (p < 0.001). Skin symptoms occurred less frequently in elderly patients (77%, p < 0.001). The clinical symptoms were more severe in the elderly (51% experiencing grade III/IV reactions), in particular when skin symptoms (p < 0.001) were absent. Most strikingly, a loss of consciousness (33%, p < 0.001) and preexisting cardiovascular comorbidity (59%, p < 0.001) were more prevalent in the elderly. Finally, adrenaline was used in 30% of the elderly (vs. 26% in the comparator group, p < 0.001) and hospitalization was more often required (60 vs. 50%, p < 0.001). Discussion and Conclusion: Anaphylaxis in the elderly is often caused by insect venoms and drugs. These patients suffer more often from cardiovascular symptoms, receive more frequently adrenaline and require more often hospitalization. The data indicate that anaphylaxis in the elderly tends to be more frequently life threatening and patients require intensified medical intervention. The data support the need to recognize anaphylaxis in this patient group, which is prone to be at a higher risk for a fatal outcome

Narratives of liberation and narratives of innocent suffering: the rhetorical uses of images of Iraqi children in the British press

This article analyses the rhetoric of pictures of Iraqi children in the British press during the 2003 UK/US invasion of Iraq. The author argues that images of children are particularly potent resources for constructing narratives about the motivations and outcomes of war. Two narratives are explored: the first is sceptical about the legality of the war but nonetheless frames its outcomes within a narrative of liberation. The second, the narrative of the innocent children, shows how the display of the children as abstracted from their social and familial context and therefore in need of adult care may be used to justify the very same military interventions that caused their injuries. The author concludes that it is not proximity or distance from the ‘suffering other’ that shapes whether or not their images will be circulated in the press, but the rhetorical uses of the image in contributing to particular narratives about the causes and consequences of specific events

Anti-HIV antibodies in the CSF of AIDS patients: a serological and immunoblotting study.

CSF and serum samples from 16 AIDS patients were tested for the presence of anti-HIV antibodies either by classical serological methods or by an immunoblot technique based on agarose gel isoelectric focusing and transfer of the specific IgG antibodies onto HIV antigens-loaded nitrocellulose sheets. This method enabled the demonstration of an intrathecal synthesis of anti-HIV oligoclonal IgG antibodies, often superimposed on diffuse polyclonal production, in 14 patients. The two negative cases were devoid of neurological signs or symptoms. However, two patients classified in stage II of the disease (asymptomatic infection) displayed an intrathecal synthesis of anti-HIV antibodies

Relation Between Oxidative Stability and Composition in Argentinian Olive Oils

The relation between oxidative stability and composition in 58 virgin olive oils from different cultivars and Argentinian regions was studied over four harvest years. The oxidative stability of the oils was assessed using the OSI index (110 °C, 20 L/h air flow). A multiple linear regression model is proposed using OSI values as the dependent variable (multiple R = 0.933, p = 1 x 10-15), with positive contributions of the independent variables: fatty acid composition [oleic acid/(linoleic acid ? linolenic acid), 55.3%, p = 1 x 10-15], total polyphenols (24.1%, p = 1.8 x 10-9), carotenes (4.8%, p = 6.1 x 10-5), β-toco- pherol (1.9%, 6.0 x 10-3) and other compounds (13.9%). Highly significant correlation was observed between oxidative stability indexes estimated by the compositional model and those experimentally determined by Rancimat method (b = 0.981, R = 0.924). Chlorophylls and Δ-5- avenasterol contributions to the model were non-significant when variables related with fatty acids and polyphenols were included. The results suggest that the fatty acid composition and the polyphenol content are the main factors that affect the oxidative stability of olive oils. The proposed model allows the estimation of the oxidative stability in olive oils independently of the cultivar. The model was obtained also taking into account samples that lie ossut of the international legal limits in some compositional values due to natural variations.Fil: Ceci, Liliana Noemí.
