RESUMO
Los murciélagos son mamíferos vertebrados presentes en la Ciudad de Buenos Aires, estimándose una población de 4 animales por habitante. Son portadores de varias enfermedades importantes y además empeoran las condiciones respiratorias de enfermos crónicos. En el campo cumplen una interesante función, ya que se alimentan de insectos perjudiciales para las siembras. El guano puede ser útil en el abono de la tierra debido al aporte de carbono y nitrógeno. En las ciudades su presencia tiene consecuencias diferentes. Se encuentran en los taparrollos de las habitaciones, así como también en todas las oquedades de muros, árboles, grietas, etc. Se exponen aquí los peligros y los cuidados que deben tenerse en la Ciudad de Buenos Aires ante la invasión de estos quirópteros.

Bats are vertebrate mammals present in the City of Buenos Aires, with an estimated population of 4 animals per inhabitant. They are carriers of several important diseases and also worsen the respiratory conditions of the chronically ill. In rural areas they fulfill an interesting function, since they feed on insects harmful to crops. Guano can be useful in soil fertilization due to its contribution of carbon and nitrogen. In cities their presence has different consequences. They are found in the roll covers of the rooms as well as in all the hollows of walls, trees, cracks, etc. The dangers and precautions to be taken in the city of Buenos Aires in the face of the invasion of these chiroptera are described here.

BACKGROUND: IgE sensitization (atopy) to pets is commonly evaluated using pet dander extracts. However, the diagnosis by components seems to be more adequate to evaluate the clinical relevance (allergy) of sIgE sensitization. OBJECTIVE: To study the association between IgE sensitization to pet allergen components and clinical symptoms. Methodology. Dander extracts and sIgE levels to pet components (Can f 1, Can f 2, Can f 3, Can f 5, Fel d 1, Fel 2, and Fel 4) were measured in a rhinitis group (n = 101) and a control group (n = 101) and a control group (. RESULTS: Dog (34.6% vs. 23.5%) and cat dander (26.7% vs. 8.8%, p = 0.05) IgE sensitization was frequent among rhinitis and no-rhinitis subjects, and it was similar to dog (29.7% vs. 20.5%) and cat (18.8% vs. 8.8%) components. Polysensitization for dog (3.1, 95% CI: 1.5 to 6.1, p = 0.05) IgE sensitization was frequent among rhinitis and no-rhinitis subjects, and it was similar to dog (29.7% vs. 20.5%) and cat (18.8% vs. 8.8%) components. Polysensitization for dog (3.1, 95% CI: 1.5 to 6.1, p = 0.05) IgE sensitization was frequent among rhinitis and no-rhinitis subjects, and it was similar to dog (29.7% vs. 20.5%) and cat (18.8% vs. 8.8%) components. Polysensitization for dog (3.1, 95% CI: 1.5 to 6.1. CONCLUSIONS: Sensitization to pet dander extract identifies atopic patients, but its utility to predict clinical relevance is poor. Allergenic components could help to define the clinical relevance of sensitization to furry animals and could reduce the need for provocation test.

BACKGROUND: To diagnose and treat respiratory allergic diseases, it is important to identify the specific allergens involved. Many differences exist between common inhalant allergens depending on the residential environment and demographic factors. This study aimed to compare common inhalant allergens between Koreans and non-Koreans according to their residential region, age, and sex. METHODS: This study evaluated 15,334 individuals who underwent serum tests for multiple allergen-specific immunoglobulin E at a tertiary academic medical center between January 2010 and December 2016. The individuals included 14,786 Koreans and 548 non-Koreans. The AdvanSure™ Allostation assay (LG Life Science, Korea) was used to test for 33 inhalant allergens. RESULTS: The house dust mite (HDM) was the most common allergen in both Koreans and non-Koreans, although the proportion of individuals with HDM sensitization was greater among Koreans. High sensitization rates for various pollen types were detected among Koreans in Gangwon region, whereas Japanese cedar pollen was unique among Koreans in Jeju region. Grass pollen and animal dander were relatively common among individuals from the Americas, whereas weed and grass pollen accounted for the 10 most common allergens for individuals from Central Asia. The total sensitization rate, sensitization to HDM, and sensitization to animal dander peaked among adolescents and young adults, then subsequently decreased with age. CONCLUSIONS: This large-scale study demonstrates that various regional and age-related differences exist in the allergen sensitization rates of Koreans and non-Koreans. These data could be useful for development of avoidance measures, immunotherapy for causative allergens, and policymaking regarding allergic diseases.
