Multiple food hypersensitivity as a cause of refractory chronic constipation in adults
2006
Chronic constipation that is unresponsive to laxative treatment is a severe illness, but children unresponsive to laxatives have been successfully treated with an elimination diet. We report the first cases of refractory chronic constipation caused by food hypersensitivity in adults. Four patients with refractory constipation who were unresponsive to high doses of laxatives were put on an oligo-antigenic diet and underwent successive double-blind, placebo-controlled, food challenges (DBPFC). Routine laboratory tests, immunological assays, colonoscopy, esophago-gastroduodenoscopy and rectal and duodenal histology were performed. While on an elimination diet, bowel habits normalized in all pa…
The international EAACI/GA²LEN/EuroGuiDerm/APAAACI guideline for the definition, classification, diagnosis, and management of urticaria
2022
This update and revision of the international guideline for urticaria was developed following the methods recommended by Cochrane and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group. It is a joint initiative of the Dermatology Section of the European Academy of Allergology and Clinical Immunology (EAACI), the Global Allergy and Asthma European Network (GALEN) and its Urticaria and Angioedema Centers of Reference and Excellence (UCAREs and ACAREs), the European Dermatology Forum (EDF; EuroGuiDerm), and the Asia Pacific Association of Allergy, Asthma and Clinical Immunology with the participation of 64 delegates of 50 national and international soci…
Pruritus characteristics in a large Italian cohort of psoriatic patients
2019
Background: Psoriasis (Ps) is a chronic systemic autoimmune disease associated with pruritus in 64–98% of patients. However, few modestly sized studies assess factors associated with psoriatic pruritus. Objective: To investigate factors associated with Ps pruritus intensity. Methods: Psoriasis patients 18 years or older seen in one of 155 centres in Italy between September 2005 and 2009 were identified from the Italian PsoCare registry. Patients without cutaneous psoriasis and those with missed information on pruritus were excluded. Results: We identified 10 802 patients, with a mean age 48.8 ± 14.3 years. Mild itch was present in 33.2% of patients, moderate in 34.4%, severe in 18.7% and ve…
Mosquito Magnet ® traps as a potential means of monitoring blackflies of medical and veterinary importance
2021
Mosquito Magnet® traps, deployed in widespread parts of England as part of nationwide mosquito surveillance projects, also caught blackflies. As many as 1242 blackflies were caught in a trapping session lasting 4 days. Principal among the species caught were Simulium equinum, Simulium lineatum and Simulium ornatum s.l. As S. ornatum s.l. is a vector that transmits Onchocerca linealis to cattle and S. equinum is responsible for dermatitis ('sweet itch') in cattle and horses, it is suggested that Mosquito Magnet® traps could be used to monitor and partially control these pests, as well as nuisance anthropophilic blackflies such as Simulium posticatum that can cause simuliidosis in southern En…
Copolymers sensitive to temperature and pH in water and in water+oil mixtures: A DSC, ITC and volumetric study
2011
Block copolymer micelles are receiving an increasing interest because of the variety of structures and the possibilities to tune them by changing external and internal parameters achieving the desired properties for a specific purpose. We have investigated the acid/base behavior, self-assembling and solubilization ability towards polar oils of star-like copolymers named Tetronics. They are composed of branched four-arms each one consisting of two blocks made of EO and PO units linked to the diethylenediamine group, which confers pH response ability. The copolymers T1107 and T90R4 were studied with a sequential and reverse architecture. The thermodynamics of the acid/base equilibrium was stu…
The care pathway for children with urticaria, angioedema, mastocytosis
2015
Cutaneous involvement characterized by urticarial lesions with or without angioedema and itch is commonly observed in routine medical practice. The clinical approach may still remain complex in real life, because several diseases may display similar cutaneous manifestations. Urticaria is a common disease, characterized by the sudden appearance of wheals, with/without angioedema. The term Chronic Urticaria (CU) encompasses a group of conditions with different underlying causes and different mechanisms, but sharing the clinical picture of recurring wheals and/or angioedema for at least 6 weeks. Hereditary Angioedema (HAE) is a rare disorder characterized by recurrent episodes of non-pruritic,…

Effect of Polymer Length on the Adsorption onto Aluminogermanate Imogolite Nanotubes
2021
This study evidences the adsorption of model nonionic polymers onto aluminogermanate imogolite nanotubes, attractive porous nanofillers with potential molecular loading and release applications. We resolve the underlying mechanisms between nanotubes and polyethylene glycols with different molecular weights by means of nanoisothermal titration calorimetry. The analysis of the results provides a direct thermodynamic characterization, allowing us to propose a detailed description of the energetics involved in the formation of polymer/imogolite complexes. The affinity toward the nanotube surface is enthalpy-driven and strongly depends on the polymer chain length, which significantly affects the…
Real-life practice: rapid improvement in itch symptomatology in patients with atopic dermatitis treated with dupilumab
2019
Sir,Atopic dermatitis is a chronic relapsing inflammatory skin disorder that affects up to 20% of children and 2–5% of the adult population (1). The disease is characterized by erythematous, xeroti...
Avaluació i anàlisi de tutoríes virtual realitzades amb estudiants d'Enginyeria
2010
En aquest article, els autors descriuen com l'ús de plataformes de treball col·laboratiu ajuda a la millora de competències d'estudiants d'enginyeria, així com a la millora contínua de la qualitat de l'ensenyança. Conseqüentment, a través de la implicació dels estudiants que han participat activament en l'experiència d'innovació docent, s'ha aconseguit l'objectiu principal de l'estudi proposat. Els resultats obtinguts mostren amb èxit el grau d'impacte en la qualitat de la docència (concretament en allò relacionat amb tutories docents) a través de l'ús d'una nova plataforma de treball col·laboratiu: ConferenceXP.
