[Anatomic and topographic models of the cerebral areas that activates during the linguistic functions].

Aim: A brief revision was performed in order to develop a topographic model of cerebral activation during silent reading, syllable's repetition and emotional prosody, based in recent neuroimaging studies.

Development: It has been reported that the words are analyzed in both occipital hemispheres during silent reading, after they are 'written' in the right temporal cortex while the integration of the semantic and phonologic processes are integrated on different left temporal areas and also in the left frontal lower part. The understanding is achieved in the left-middle temporal cortex.

[Desensitization to human recombinant DNA insulin in an adolescent with insulin-dependent diabetes mellitus].

Background: Adverse reactions to drugs have increased in the last years, about 15% of all side effects are thought to be immune mediated according to the Coombs and Gell classification they can be type I (immediate) hypersensitivity, type II (cytotoxic) type III (immune complex mediated) or type IV (delay). Allergy to insulin is defined as an immunological response type I, and type II or III to exogenous insulin solutions occurring the 0.1% and 0.
