    Exposición a monóxido de carbono en trabajadores de control vehicular-Cuenca: estudio exploratorio
    (Universidad de Cuenca, 2015-09) Rosas, Ruth; Ochoa, Angélica; Morillo, Diana; García, Nancy; Andrade, Susana
    This exploratory study aims to evaluate the carbon monoxide exposure expressed as percentage of carboxyhemoglobin (%COHb) among the vehicle-examiners of the vehicle control centers (VCC) “DANTON”-Cuenca. All the employees (N=55) in both VCCs in Cuenca (Capulispamba and Mayancela) were included. Blood samples taken at the beginning and at the end of the journey of one day at early February, April and July 2013 were used to estimate %COHb. The results show that the %COHb increased from the beginning to the end of the journey among employees in both VCCs and among smokers and nonsmokers (P<0.001). Among non-smokers (N=42), the %COHb at the end of the journey was higher than the biological limit value (BLV) of 3.5% only for Mayancela employees (4.12%, P<0.05). Among smokers, the mean %COHb at the end of the journey was higher than the BLV in both VCCs. In general, Mayancela employees and those who smoke showed higher exposition to CO measured as a %COHb.

    Prevalencia de alergia alimentaria auto-reportada en adolescentes de Cuenca y Santa Isabel - Ecuador
    (Universidad de Cuenca, 2016-09) Morillo Argudo, Diana Alexandra; Ochoa Avilés, Angélica María; Rodas, Claudia; Córdova, Diana; Zúñiga, Gabriela; García, Ana; Chávez, Ana Cristina; Ramírez, Patricia; Andrade, Susana
    Food allergy (FA) is associated with the development of atopic diseases and anaphylaxis in adolescents. It was determined and compared among adolescents Cuenca and Santa Isabel: i) self-reported FA prevalence, ii) common food allergens and iii) self-reported atopic diseases. Crosssectional study was conducted in adolescents from Cuenca (n = 967) and Santa Isabel (n = 498) between July 2013 and July 2014. Data were collected through self-reported FA questionnaires. The prevalence of self-reported FA was 27.8% (Cuenca 31.5% vs. Santa Isabel 21.1 %; P <0.001). Additives were the major foods reported followed by the non-citrus fruits. 20.4% of adolescents who reported atopic diseases also reported suggestive symptoms of FA, while 7.4% of adolescents who reported suggestive symptoms of FA didn’t report atopic diseases (OR 3.39, 95% CI 2.6 to 4.4, P <0.001). In conclusion, self-reported additives and non-citrus fruits allergy were the most prevalent among adolescents in Cuenca and Santa Isabel. New foods usually not reported were identified. Adolescents with atopic disease were three times more likely to report FA than those who did not have atopic diseases.
