Long-term survival and outcome after first stroke in the Sicilian Aeolian Island Archipelago population.
2007
Background: Only a restricted number of population studies based on long-term prognosis after a stroke have been published. We analyzed long-term survival and outcome in insular first-ever stroke population from the Aeolian Archipelago. Subjects and methods: From 1 July, 1999 to 30 June 2002, 62 patients with first-ever stroke were recruited to evaluate short-term incidence and outcome. Information for every patient was collected by phone interviews after 3 months, 1 year, and 4 years. Results: 30 days case fatality rate was 24.2% (95% C.I. 14.22 to 36.75). Fifty-one percent (95% C.I. 35.8 to 66.3) of patients died before last survey and 39.1% died during the first year of follow-up. Annual…
The Balearic toad (Bufo viridis balearicus (BOETTGER, 1881)), human bronze age culture, and Mediterranean biogeography
1981
Abstract Microcomplement fixation analysis of albumin relationship shows that the Balearic green toad (Bufo viridis balearicus) is not an original, autochthonous member of the basically Miocene fauna of these western Mediterranean islands, but a quite recent newcomer. The plasma protein pattern clearly points to its close populational relationship to the Tyrrhenian islands' conspecifics. The male and female release vocalization shows the same, and this is in accordance with the external morphology too. There has been no possibility for toads to reach the Balearic Islands in Pleistocene or Holocene via land bridges, nor are they candidates for any sea drifting. Anthropogenic introduction mu…
A comparison of the structure of helminth communities in the woodmouse, Apodemus sylvaticus, on islands of the western Mediterranean and continental …
2003
We investigated the pattern of helminth species diversity in woodmouse, Apodemus sylvaticus, on western Mediterranean islands. We first performed a survey of the helminth fauna of A. sylvaticus in Sicily. Despite the small sampling effort, parasite species richness in Sicily is large in comparison with parasite species richness on other Mediterranean islands. We tested the nestedness of helminth parasite species from a number of Mediterranean localities using data compiled from epidemiological surveys of the helminth species of A. sylvaticus. We showed a nested pattern for woodmouse helminth species on western Mediterranean islands which suggests that the distribution of parasites on these …
Mycobacterium tuberculosis molecular evolution in western Mediterranean Island of Sicily and Sardinia
2004
Abstract In this study, a total of 204 Mycobacterium tuberculosis DNAs from Sicily ( n = 144) and Sardinia ( n = 60) were studied by three genotyping methods. Results were analyzed both within and across islands, to define the phylogeographical specificities of the genotypes, look for their diversity and infer a molecular evolutionary scenario. A strong link between geography and tuberculosis genotypes was observed in Sardinia. The results were also matched against a world-wide genetic diversity database to compare the population structure of the tubercle bacilli in the islands. Eight common genotypes between Sicily, Sardinia and continental Italy were found which underlines the influences …
Mitochondrial DNA haplotype frequencies in natural and experimental populations of Drosophila subobscura.
1998
Abstract The evolution of Drosophila subobscura mitochondrial DNA has been studied in experimental populations, founded with flies from a natural population from Esporles (Majorca, Balearic Islands, Spain). This population, like other European ones, is characterized by the presence of two very common (>96%) mitochondrial haplotypes (called I and II) and rare and endemic haplotypes that appear at very low frequencies. There is no statistical evidence of positive Darwinian selection acting on the mitochondrial DNA variants according to Tajima's neutrality test. Two experimental populations, with one replicate each, were established with flies having a heterogeneous nuclear genetic back…

Health status, diseases and vaccinations of the homeless in the city of Palermo, Italy.
2018
Introduzione. Un tempo "barboni", oggi senzatetto, il loro numero sta aumentando considerevolmente negli ultimi anni. Molti di loro soffrono di malattie croniche, problemi di salute mentale, dipendenze e necessitano di cure mediche complesse. Il loro stato di salute è spesso esacerbato per maggiori difficoltà nell'accesso alle cure primarie rispetto alla popolazione generale. Materiali e Metodi. È stato distribuito un questionario autosomministrato al fine di valutare le condizioni di salute dei senzatetto che vivono a Palermo. È stato utilizzato un modello di regressione logistica multivariata calcolando gli Odds Ratios aggiustati (aOR). Risultati. Il campione è costituito da 52 senzatetto…
Seasonal variation of air kerma in the "Vulcano Porto" area (Aeolian Islands, Italy).
2001
Abstract Air kerma was measured in the “Vulcano Porto” area of the Vulcano Island, belonging to the Aeolian Islands, in the Mediterranean Sea. Measurements were carried out using thermoluminescence dosimeters. The relationship between observed dose values and source lithology has been assessed. Data show a seasonal variation due to weather conditions but also probably related to features of the soils, making the variation more evident.
The agricultural heritage of Lampedusa (Pelagie Archipelago, South Italy) and its key role for cultivar and wildlife conservation
2011
As occurred on many other little Mediterranean islands, agricultural activity at Lampedusa (Strait of Sicily) underwent a very strong decline in terms of surface area during the second half of the last century. In particular, cereal crops have ceased and horticulture is disappearing, while vineyards still occupy a reduced area but are quickly vanishing and currently survive thanks to a small number of old farmers. Here are presented the results of a research carried out by interviewing seven farmers in order to study not only the techniques and the germplasm used in local viticulture, but also the final use of grapes and an evaluation on the connection between traditional farming and agro-e…
Spatial variability of ecophysiological performances and invasive potential of alien acacias (Acacia spp.) in Sicily and Lampedusa island (Pelagie Ar…
2012
Acacia spp. are among the most widespread and prominent invaders within Mediterranean-type ecosystems, where have already shown the capability to deeply change the characters and the functioning of invaded ecosystems (like in Portugal or S Africa: e.g. Holmes & Cowling, 1997; Hellmann et al., 2011). In Sicily, just in the last few years, two Australian Acacias, notably Acacia cylops A. Cunn. ex G. Don and A. saligna (Labill.) H.L.Wendl., started to regenerate abundantly within different areas (especially afforested sites). However their naturalization process has not been studied up to now.
