Dolido por la escasa repercusión y el nulo interés de la geografía (crítica) estadounidense ante los atentados de Al Qaeda en Madrid, el cuaderno de viaje de Margarita del Vez (participante en el 100 Congreso de la Association of American Geographers) reprocha no sólo que el conocimiento geográfico sigue siendo mercantilizado y puesto al servicio del poder, sino que, descontextualizado y desideologizado, a menudo se convierte en una nueva forma de «saber ignorante». Con la deconstrucción formal de la narrativa «científica», el texto pretende ser también una denuncia al hecho de que la institución académica, por guardar las formas, llegue al extremo de dar la espalda a la realidad.

La extracción del tercer molar inferior incluido provoca efectos secundarios como dolor, inflamación y trismo. Presentamos un estudio cuyo objetivo fue relacionar la edad, el sexo, el tabaco y la higiene oral con el postoperatorio de 100 de terceros molares inferiores incluidos. La edad, el sexo y el consumo de tabaco no influyeron significativamente en el postoperatorio. Sólo hallamos una correlación estadísticamente significativa entre la higiene oral y el dolor a las 6 horas de la exodoncia.

Se describe la estructura y el patrón espacial de un ecotono bosque subalpino-pastos alpinos dominado por Pinus uncinata Ram. (Pirineos Orientales, Cerdanya, Estanys de la Pera). La historia de perturbaciones de la zona sugiere que el patrón espacial del ecotono puede haber sido afectado recientemente por el pastoreo. Se situó una parcela rectangular (30 x 100 m) cruzando el ecotono con su lado mayor paralelo a la pendiente. Para cada individuo de P. uncinata dentro de la parcela se midió: su localización (coordenadas x, y), y diversas variables estructurales (diámetros basal y a 1,3 m de altura, altura, radios de las copas, número de cohortes de acículas, edad estimada -número de internodos del tronco). Los individuos vivos de P. uncinata se clasificaron según su tam±o (adultos, jóvenes, vástagos y plántulas) y forma de crecimiento (krummholz -individuos arbustivos policórmicos-). Se describieron cuantitativamente el tipo de sustrato (roca, materia orgánica, suelo) y la cobertura de herbáceas, arbustos y P. uncinata usando transectos paralelos a la pendiente. La estructura del ecotono se describió mediante: (i) los análisis del patrón de puntos (K de Ripley, casos uni- y bivariante) y (ii) del patrón de superficies (correlogramas omni- y unidireccionales de Moran). El ecotono estudiado mostró una distribución de individuos de P. uncinata en agregados, predominando los vástagos. Los análisis espaciales mostraron la existencia y el tam±o de agregados con valores similares para ciertas variables de los árboles situados dentro del bosque (p. ej. 8-10 m para la edad estimada). La edad estimada de los individuos jóvenes (60 ±os <) estaba positivamente correlacionada con la altura y el diámetro basal. La regeneración reciente presentó dos máximos (1965-67, 1973-77). Apareció una posible cohorte de individuos más viejos (1941-57). A partir de 1975, la regeneración declinó de forma exponencial. El establecimiento...

OBJECTIVE To determine the prevalence and clinical significance of hepatitis G virus (HGV) infection in a large cohort of patients with primary Sjögren¿s syndrome (SS). PATIENTS AND METHODS The study included 100 consecutive patients (92 female and eight male), with a mean age of 62 years (range 31¿80) that were prospectively visited in our unit. All patients fulfilled the European Community criteria for SS and underwent a complete history, physical examination, as well as biochemical and immunological evaluation for liver disease. Two hundred volunteer blood donors were also studied. The presence of HGV-RNA was investigated in the serum of all patients and donors. Aditionally, HBsAg and antibodies to hepatitis C virus were determined. RESULTS Four patients (4%) and six volunteer blood donors (3%) presented HGV-RNA sequences in serum. HGV infection was associated with biochemical signs of liver involvement in two (50%) patients. When compared with primary SS patients without HGV infection, no significant differences were found in terms of clinical or immunological features. HCV coinfection occurs in one (25%) of the four patients with HGV infection. CONCLUSION The prevalence of HGV infection in patients with primary SS is low in the geographical area of the study and HCV coinfection is very uncommon. HGV infection alone does not seen to be an important cause of chronic liver injury in the patients with primary SS in this area.

Coraebus undatus is the main insect pest of cork oak worldwide. The larvae tunnel in the cortical cambium filling the bark with galleries and causing the cork to break at harvest. The first objective of this study was to test the effect of purple traps in the attraction of C. undatus because this colour is attractive to other buprestid beetles. The second objective was to develop a diet in which field-collected larvae could be reared to adulthood. Pairs of purple and clear (control) sticky traps were placed in a cork oak forest in Girona, Spain in the summer of 2008

Background: Noroviruses are one of the principal biological agents associated with the consumption of contaminated food. The objective of this study was to analyse the size and epidemiological characteristics of foodborne outbreaks of gastroenteritis in Catalonia, a region in the northeast of Spain. Methods: In all reported outbreaks of gastroenteritis associated with food consumption, faecal samples of persons affected were analysed for bacteria and viruses and selectively for parasites. Study variables included the setting, the number of people exposed, age, sex, clinical signs and hospital admissions. The study was carried out from October 2004 to October 2005. Results: Of the 181 outbreaks reported during the study period, 72 were caused by Salmonella and 30 by norovirus (NoV); the incidence rates were 14.5 and 9.9 per 100,000 person-years, respectively. In 50% of the NoV outbreaks and 27% of the bacterial outbreaks (p = 0.03) the number of persons affected was ≥10; 66.7% of NoV outbreaks occurred in restaurants; no differences in the attack rates were observed according to the etiology. Hospitalizations were more common (p = 0.03) in bacterial outbreaks (8.6%) than in NoV outbreaks (0.15%). Secondary cases accounted for 4% of cases in NoV outbreaks compared with 0.3% of cases in bacterial outbreaks (p < 0.001) Conclusion: Norovirus outbreaks were larger but less frequent than bacterial outbreaks, suggesting that underreporting is greater for NoV outbreaks. Food handlers should receive training on the transmission of infections in diverse situations. Very strict control measures on handwashing and environmental disinfection should be adopted in closed or partially-closed institutions.

The objective of research was to analyse the potential of Normalized Difference Vegetation Index (NDVI) maps from satellite images, yield maps and grapevine fertility and load variables to delineate zones with different wine grape properties for selective harvesting. Two vineyard blocks located in NE Spain (Cabernet Sauvignon and Syrah) were analysed. The NDVI was computed from a Quickbird-2 multi-spectral image at veraison (July 2005). Yield data was acquired by means of a yield monitor during September 2005. Other variables, such as the number of buds, number of shoots, number of wine grape clusters and weight of 100 berries were sampled in a 10 rows × 5 vines pattern and used as input variables, in combination with the NDVI, to define the clusters as alternative to yield maps. Two days prior to the harvesting, grape samples were taken. The analysed variables were probable alcoholic degree, pH of the juice, total acidity, total phenolics, colour, anthocyanins and tannins. The input variables, alone or in combination, were clustered (2 and 3 Clusters) by using the ISODATA algorithm, and an analysis of variance and a multiple rang test were performed. The results show that the zones derived from the NDVI maps are more effective to differentiate grape maturity and quality variables than the zones derived from the yield maps. The inclusion of other grapevine fertility and load variables did not improve the results.
