Negative role of malnutrition in cell-mediated immune response: Pneumocystis jirovecii pneumonia (PCP) in a severely malnourished, HIV-negative patient with anorexia nervosa.

It is generally acknowledged that malnutrition is a propensity factor for secondary infections in different clinical situations (malnutrition-associated infections in hospitalized patients and malnourished children in developing countries). However, it is not clear how malnutrition might facilitate the development of opportunistic infections in human immunodeficiency virus (HIV)-negative patients without a definite etiology (disease or treatment) of impaired cell-mediated immune response. We report here on a case of Pneumocystis jirovecii pneumonia in an HIV-negative patient suffering from anorexia nervosa with extreme malnutrition, which had a favorable outcome despite the severity of her respiratory failure.

Quantitative assessment of attribution of intentions to others in schizophrenia using an ecological video-based task: a comparison with manic and depressed patients.

Schizophrenia is characterized by the impairment of several facets of social cognition. This has been demonstrated in numerous studies that focused on specific aspects of social cognition such as the attribution of intentions, emotions, or false beliefs to others. However, most of these studies relied on complex verbal descriptions or impoverished social stimuli.

Elaboration of a rehabilitation method based on a pathogenetic hypothesis of "theory of mind" impairment in schizophrenia.

"Theory of mind" skills have repeatedly been shown to be impaired in schizophrenic patients. The purpose of this paper is to develop a therapeutic intervention targeting schizophrenic patients' abilities to attribute mental states to others. This preliminary study tried to test the hypothesis that this kind of intervention should improve patients' communication abilities; we also wondered if this would have a positive impact on their more general psychopathology.
