      Surgida na literatura em 1974, a information literacy liga-se à necessidade de se exercer o domínio sobre o sempre crescente universo informacional. Incorporando habilidades, conhecimentos e valores relacionados à busca, acesso, avaliação, organização e difusão da informação e do conhecimento. A information literacy é a própria essência da competência em informação. O objetivo deste trabalho é definir a information literacy a partir do entendimento do conceito, objetivos e práticas relacionadas, com ênfase no papel educacional das bibliotecas e do bibliotecário. Inicialmente, apresenta-se a evolução do conceito segundo um referencial histórico. Examina-se a information literacy enquanto processo de interiorização de conhecimentos, habilidades e valores ligados à informação e ao aprendizado. Define-se a expressão, suas características e objetivos. Discutem-se diferentes concepções de information literacy, segundo três referenciais: informação, conhecimento e aprendizado. Em seguida, são elencados pontos relevantes de atuação de bibliotecas e bibliotecários na implementação de uma educação voltada para a information literacy. Explorando a information literacy education, evidencia-se a necessidade de construção de um novo paradigma educacional ante a sociedade atual que incorpore a competência em informação.

          Guillain-Barré syndrome.

           F. Hahn (1998)
          Guillain-Barré syndrome (GBS) is viewed as a reactive, self-limited, autoimmune disease triggered by a preceding bacterial or viral infection. Campylobacter jejuni, a major cause of bacterial gastroenteritis worldwide, is the most frequent antecedent pathogen. It is likely that immune responses directed towards the infecting organisms are involved in the pathogenesis of GBS by cross-reaction with neural tissues. The infecting organism induces humoral and cellular immune responses that, because of the sharing of homologous epitopes (molecular mimicry), cross-react with ganglioside surface components of peripheral nerves. Immune reactions against target epitopes in Schwann-cell surface membrane or myelin result in acute inflammatory demyelinating neuropathy (85% of cases); reactions against epitopes contained in the axonal membrane cause the acute axonal forms of GBS (15% of cases). Care for such patients may be challenging, yet the prognosis overall is favourable. Optimal supportive care and anticipation and prevention of complications are the mainstay of therapy. Admission to the intensive-care unit is necessary in 33% of patients who require intubation and assisted ventilation. Immunomodulation with infusions of IgG or plasma exchange treatments foreshorten the disease course.
