The aim of the present study is to analyze relationships between land uses and anthropogenic pressures, and nutrient loadings in the Po river basin, the largest hydrographic system in Italy, together with the changes they have undergone in the last half century. Four main points are addressed: 1) spatial distribution and time evolution of land uses and associated N and P budgets; 2) long-term trajectories of the reactive N and P loadings exported from the Po river; 3) relationships between budgets and loadings; 4) brief review of relationships between N and P loadings and eutrophication in the Northern Adriatic Sea. Net Anthropogenic N (NANI) and P (NAPI) inputs, and N and P surpluses in the cropland between 1960 and 2010 were calculated.

We report the case of a 62-year old man who presented a wheat-dependent, exercise-induced anaphylaxis (WDEIA). The case illustrates the usefulness of skin prick test not only with wheat extract, but also with native gliadin extract. Moreover we confirm the value of recombinant IgE dosage with rTri a 19 omega-5 gliadin in the diagnostic pathway of this condition.

Methods: General surgery residents at the University of Pittsburgh completed questionnaires measuring attitudes and knowledge about surgical ethics before and after four 60-minute, faculty-facilitated seminars implementing the American College of Surgeons ethics curriculum.
Results: Most residents experienced ethical challenges at least once every rotation: competition of interests (75%), professional obligations (75%), confidentiality (83%), truth telling (88%), surrogate decision making (91%), and end-of-life issues (100%).
In Escherichia coli, the TolC-AcrAB complex forms a major antibiotic efflux system with broad substrate specificity. During the complex assembly, the periplasmic helices and bottom turns of TolC are thought to interact with a hairpin helix of AcrA and hairpin loops of AcrB respectively. In the present study we show that a four-residue substitution in TolC's turn 1, which connects outer helices 3 and 4 proximal to TolC's periplasmic aperture, confers antibiotic hypersensitivity, without affecting TolC-mediated phage or colicin infection.

Aim Of The Study: We compared the allergenic potency of three commercial extracts for skin prick testing and evaluated batch-to-batch differences within each product.
The patch test with food antigens (atopy patch test, APT) has been reported as a more specific method than prick or RAST for the early detection of cow's milk and/or egg sensitizations in children. Standardization of APT extracts is a major issue on the road towards full clinical exploitation of this assay. Here, we used sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) to characterize sensitivity and specificity of commercial preparations of APT for milk and egg allergies, which are expected to improve the reliability of this test, when compared with fresh food allergen sources.

Background: We previously demonstrated that one year of sublingual immunotherapy (SLIT) with natural rubber latex (NRL) was safe and efficacious in paediatric patients with NRL allergy.
Research Design And Methods: We studied 12 NRL-allergic children (age 4-15), previously assigned to the treated arm of a double-blind placebo controlled study, who received a commercial latex SLIT for three years. Adverse reactions were monitored.
Background: Sublingual specific immunotherapy (SLIT) is a valid treatment for allergies. However, there are few data on a large sample size regarding its clinical role in 'real life'.
Study Aim: We performed a multicentre, case-control study to evaluate the effectiveness of SLIT in patients with allergic rhinitis (AR).
Background: Specific subcutaneous immunotherapy (SCIT) with house dust mite (HDM) preparation has recently been shown to improve eczema in patients with atopic dermatitis (AD). So far, there is less data regarding efficacy and safety of specific sublingual immunotherapy (SLIT) in patients with AD.
Study Aim: To evaluate in an open non-controlled, non-randomized pilot trial the effect of SLIT with HDM allergen extracts preparation (SLITone, ALK Abellò Italy) on SCORAD in adult patients with mild-moderate AD.
Compliance is a major determinant for allergy treatment, especially in children. Sublingual immunotherapy (SLIT) is self-managed at home, and no quantitative data on pediatric adherence are available. We studied the compliance in a large real-life setting.

Background: Due to optimal safety of sublingual immunotherapy (SLIT), it was suggested that a slow up-dosing phase maybe not necessary, and therefore the treatment will be more patient-friendly, avoiding dosing mistakes.
Patients: Twenty adult patients suffering allergic rhinitis due to Parietaria, were enrolled. Half of them received the traditional schedule and the other half immediately started with 200 STU.
Venom immunotherapy (IT) is a very effective method for the treatment of Hymenoptera venom allergy. We compared safety, efficacy, and modulation of specific immunologic parameters in 70 patients sensitized to Apis mellifera, treated for > or = 5 years with standardized quality (SQ) aqueous IT, either with a rush (n = 20) or with a cluster (n = 20) induction protocol, or with an SQ depot extract and a cluster induction protocol (n = 30). We made an open, noncontrolled study.

Medical statistics may contribute to ameliorate research by improving the design of studies and identifying the optimal method for the analysis of results. Sometimes, nevertheless, it could be misemployed flawing the benefit potential. Allergic diseases pathogenesis is recognized to be systemic but global initiatives such as GINA and ARIA documents define allergic asthma and rhinitis as organ diseases; such an asymmetrical view raises a set of known and unknown confounding that could influence the quality of the process of evidence-based decision-making (topic symptomatic therapeutic interventions versus systemic pathogenetic interventions).
View Article and Find Full Text PDFBackground: Allergic rhinitis is induced by an IgE mediated inflammation after allergen exposure of the membranes lining the nose which, in predisposed individuals, may constitute a risk factor for the occurrence of asthma.
Objective: To detect early changes in nasal inflammation after allergen exposure, 11 children [9.0 (7, 11) yrs], sensitized to house dust mites (HDM), with rhinoconjunctivitis and asthma and an age- and gender-matched control group (Ctr) were studied.
Parallel follow-up of clinical and inflammatory markers during sub-lingual immunotherapy (SLIT) is highly beneficial. Twenty-four children (age 4-16) monosensitized to house dust mite were randomized to receive either active or placebo SLIT for 1 yr in a double-blind placebo controlled design (Marcucci et al., Allergy 2003: 58: 657-62).

Objective: We sought to study the safety and efficacy of injective immunotherapy in European patients sensitized to Ambrosia artemisiifolia.
Methods: Thirty-two patients (18 M/14 F, mean age 36.
Background: In atopic subjects, dysfunctions of the upper and lower airways frequently coexist and allergic rhinitis seems to constitute a risk factor for the occurrence of asthma in predisposed individuals.
Aim Of The Study: To evaluate whether in atopic subjects nasal inflammation could reflect changes in respiratory functions, 11 allergic children, sensitized to house dust mites (HDM), with rhinoconjunctivitis and asthma and 10 nonatopic controls (ctrs) were studied.
Methods: All subjects underwent nasal brushing to detect percentages of nasal eosinophils (Eos %) and intercellular adhesion molecule-1 (ICAM-1) expression by nasal epithelial cells.
Background: Clinical documentation about effects on local markers of inflammation of sublingual immunotherapy (SLIT) in children is still poor.
Methods: Twenty-four children (age range 4-16 years, average 8.5 years) monosensitized to house dust mites (HDMs) were randomized to receive active or placebo SLIT for this allergen according to a double-blind, placebo-controlled design.
