Sustainable development in international law making and trade: International food governance and trade in agriculture

This timely book provides an accessible insight into how the concept of sustainable development can be made operational through its translation into legal terms. Understood as a multidimensional legal principle, sustainable development facilitates coherent international law making. Using this notion as an analytical lens on the WTO Agreement on Agriculture, the book considers the unresolved question of what a sustainable and coherent agricultural trade agreement could look like.

Novel insights into mechanisms of food allergy and allergic airway inflammation using experimental mouse models

Over the last decades, considerable efforts have been undertaken in the development of animal models mimicking the pathogenesis of allergic diseases occurring in humans. The mouse has rapidly emerged as the animal model of choice, due to considerations of handling and costs and, importantly, due to the availability of a large and increasing arsenal of genetically modified mouse strains and molecular tools facilitating the analysis of complex disease models. Here, we review latest developments in allergy research that have arisen from in vivo experimentation in the mouse, with a focus on models of food allergy and allergic asthma, which constitute major health problems with increasing incidence in industrialized countries. We highlight recent novel findings and controversies in the field, most of which were obtained through the use of gene-deficient or germ-free mice, and discuss new potential therapeutic approaches that have emerged from animal studies and that aim at attenuating allergic reactions in human patients.

Eosinophilic esophagitis: analysis of food impaction and perforation in 251 adolescent and adult patients

BACKGROUND ; AIMS: Eosinophilic esophagitis is a rapidly emerging, chronic inflammatory disorder. Prolonged inflammation evokes structural alterations and a fragile esophageal wall prone to perforation/rupture and food impaction. This report assesses the risk of spontaneously arising and procedure-induced complications and proposes practical recommendations. METHODS: The Swiss Esophageal Esophagitis Database documented 251 confirmed cases. A chart review identified which patients had required endoscopic bolus removal and/or experienced transmural esophageal perforation/rupture. In addition, a MEDLINE search for "eosinophilic esophagitis" with "esophageal perforation" or "esophageal rupture" was undertaken. RESULTS: During an 18-year period, 87 patients (34.7%) experienced 134 food impactions requiring flexible (124, 92.5%) or rigid (10, 7.5%) endoscopic bolus removal. Transmural perforation occurred in 20% (2/10) of rigid procedures, and 1 esophageal rupture (Boerhaave's syndrome) was observed. CONCLUSIONS: Bolus removal by rigid endoscopy is a high-risk procedure and should be avoided in eosinophilic esophagitis patients who require a gentler approach. Whether food impaction and esophageal wall remodeling can be prevented with anti-inflammatory medication is still undetermined. All Boerhaave's syndrome cases should be evaluated for underlying eosinophilic esophagitis.
