Selective IgA deficiency (SIgAD) is the most prevalent immunodeficiency worldwide, progressing to common variable immunodeficiency only in few reported cases. We report the case of a Spanish female aged 22 and diagnosed of selective IgA deficiency, a long history of bronchitis, several episodes of pneumonia, bilateral bronchiectasis, normal IgG, IgM, IgG subclasses, and detectable pre-vaccination IgG antibodies against tetanus toxoid and Streptococcus pneumoniae. She was evaluated in our clinic in order to rule out common variable immunodeficiency. We observed good antibody response to tetanus toxoid, absence of circulating switched memory B cells, decreased response to pneumococcal polysaccharide antigens and a lack of response to Salmonella typhi vaccine. Most SIgAD patients presents with upper respiratory tract infections or mild diarrhea. Those with lower tract infections, pneumonia or untreatable diarrhea should follow B-cell subpopulations' study and antibody response to vaccines. Absence of response to Salmonella typhi vaccine allowed us to expose the defective antibody production. [ABSTRACT FROM AUTHOR]

Inflation expectations are key unobservable variables for decision-making, especially in managing monetary policy. Understanding how to formulate them, if they are rational or adaptive, is vital. This study answers these questions through a panel data analysis of the micro data from the inflation expectation survey of the Central Bank of Uruguay. The main findings indicate: i) a low predictive power of the analysts surveyed in the 12-month horizon; ii) a convergence of the individual forecasts to the released monthly median; iii) an overweight of the inflation target ceiling and the dynamics of inflation; and iv) an underweight of monetary policy instruments. With respect to the evidence of rationality, we find the partial use of available information and, in some cases, there is a systematic bias. [ABSTRACT FROM AUTHOR]

El artículo presenta un análisis sobre el traspaso de las tasas de interés en el sistema bancario uruguayo. Se destaca la política monetaria implementada por el Banco Central del Uruguay, utilizando una tasa de interés nominal de corto plazo como instrumento operativo en un régimen de metas de inflación flexible.

The purpose of this article is to discuss what type of integration Uruguay should be sought in the context of global system-wide changes occurring since the fall of the Berlin Wall. This work is structured with the intention of linking three distinct but closely related levels. First, in what way Uruguay's foreign policy is impacted by the growing need to interact with an increasingly globalized -as opposed to merely international- world. Second, how can we redefine the link between the country and a globalized world, and with a region that is the geographic area with which it has a natural imperative to become integrated. Third -and a consequence of the aforementioned-, what sort of actions could be undertaken to adapt the country's international position to the remarkable changes happening in the midst of the international system. The paper ends with some thoughts on the country's productive sectors and the types of organization deemed the most suitable to transform them into export engines in the current regional and international scenario.

El articulo trata la situación de a lengua mapuche (mapuzugun) al enfrentar el proceso creciente de hispanización de lés comunidades mapuches de a Argentina. El trabajo se plantea a partir de datos que proceden de una investigacion de campo en algunas comunidades y escuelas mapuches desarrollada en septiembre de 2001, como parte de un proyecto de investigacion del Centro Interdipartimentale di Studi sull'America Indigena de la Universidad de Siena -a la cual pertenecen los dos autores italianos, Canuti y Giannelli- sobre el bilingüismo mapuche-castellano, que tuvo en la Argentina la colaboración del Programa de Investigación Geogràfico Politico Patagónico de la Universidad Católica Argentina con sede en Buenos Aires, dirigido por el otto autor, Alex H. Vallega. Después de una ilustración sobre la historia y la situación actual de las comunidades mapuches y de las caracteristicas del trabajo, se ofrecen datos sobrela situación sociolingóistica, considerando las clãsicas variables sociales. Los datos recogidos por medio de cuestionarios auto-evaluativos muestran una lengua amenazada, tal vez con diferencias geograficas, pero siempre con una idiosincrasia fuerte y creciente, con una actitud ideologica positiva hacia la lengua nativa y una dificultad en la pràctica del mapuzugun. Se advierte que rara vez es la primera lengua de los más jóvenes y existe una tendencia a restringir su empleo a pocos dominios. Dentro de esta tendencia general, se encuentran elementos complejos. como un proceso limitado de rescate (parcial) de la lengua por parte de adolescentes que tienen el castellano como primera lengua.
