Evaluation of the prevalence of skin prick test positivity to Alternaria and Cladosporium in patients with suspected respiratory allergy. A European multicenter study promoted by the Subcommittee on Aerobiology and Environmental Aspects of Inhalant Allergens of the European Academy of Allergology and Clinical Immunology.This trial was undertaken to study, in several geographically spread European countries, the prevalence of skin prick test (SPT) positivity to Alternaria (A) and Cladosporium (C) in subjects with nasal and/or bronchial symptoms of suspected allergic cause. Each patient completed an anamnestic questionnaire and underwent SPT with a panel of common inhalant allergens and also A and C supplied by three different laboratories, to allow for manufacturer bias. Specific scrum IgE determination was carried out only in subjects with SPT positivity to A and/or C with an immunoassay system. In nine European allergology centers, a total of 877 subjects was enrolled in the trial; 83 of them showed SPT positivity to A and/or C; only nine patients showed monosensitization to A, and none to C The highest percentage of positive subjects was found in Spain (20%); the lowest in Portugal (3%). In the other seven centers, the variation was 7–10%. The age range of mold-positive subjects was 5–60 years. Rhinitis was by far the most common symptom, whether associated or not with asthma and/or conjunctivitis.

Notes: Abstract Volcanic catastrophes constitute a majorproblem in many developing and developed countries. Inrecent years population growth and the expansion ofsettlements and basic supply lines (e.g., water, gas,etc.) have greatly increased the impact of volcanicdisasters. Correct land-use planning is fundamental inminimising both loss of life and damage to property.In this contribution Geographical Information Systems(GIS), linked with remote sensing technology andtelecommunications/warning systems, have emerged asone of the most promising tools to support thedecision-making process. Some GIS are presented fortwo volcanic areas in Italy, Mt. Etna and Vesuvius.GIS role in risk management is then discussed, keepingin mind the different volcanic scenarios of effusiveand explosive phenomena. Mt. Etna system covers alarge area (more than 1,000 km2) potentiallyaffected by effusive phenomena (lava flows) whichcause damage to both houses and properties in general.No risk to life is expected. The time-scales of lavaflows allow, at least in principle, modification ofthe lava path by the building of artificial barriers.Vesuvius shows typically an explosive behaviour. Inthe case of a medium size explosive eruption, 600,000people would potentially have to be evacuated from anarea of about 200 km2 around the Volcano, sincethey are exposed to ruinous, very fast phenomena likepyroclastic surges and flows, lahars, ash fallout,etc. Ash fallout and floods/lahars are also expectedin distal areas, between Vesuvius and Avellino,downwind of the volcano. GIS include digital elevationmodels, satellite images, volcanic hazard maps andvector data on natural and artificial features (energysupply lines, strategic buildings, roads, railways,etc.). The nature and the level of detail in the twodata bases are different, on the basis of thedifferent expected volcanic phenomena. The GIS havebeen planned: (a) for volcanic risk mitigation (hazard,value, vulnerability and risk map assessing), (b) toprovide suitable tools during an impending crisis, (c)to provide a basis for emergency plans.
