In an information processing approach, this paper attempt to show how different levels of processing visual information can be organized Sensory processing makes local coding of some dimensions. Then comme a step of structuration consisting in "putting together" these locally coded dimensions. These informations have finally to be interpreted on the basis of cognitive representations. Several examples are presented illustrating how ambiguities can appear between sensory information and various cognitive interpretations.

[Methotrexate and non-steroidal anti-inflammatory agent combination in rheumatoid arthritis].

It is well known that methotrexate (MTX), used at high dosage in cancer patients, must not be combined with a non-steroidal anti-inflammatory drug (NSAID) because of high risk of side effects; prescribed at low dosage (< or = 15 mg per week) in rheumatoid arthritis patients, MTX is often combined with an NSAID. Some cases reported in the literature underline the potential toxicity of the association of low dose MTX with an NSAID, but most of the pharmacological studies do not confirm this hypothesis. Except for salicylates, NSAIDs do not affect the absorption, distribution, protein binding, area under the curve, half-life, or the elimination of MTX. Therefore, if necessary, MTX (< or = 15 mg per week) can be combined with an NSAID during the treatment of rheumatoid arthritis.
