Objective: To characterize the presentation of burns in children and risk factors associated with their occurrence in a developing country as a basis for future prevention programs. Design: Case-control study. Setting: Burn unit of the National Institute of Child Health (Instituto Nacional de Salud del Niño) in Lima, Peru. Methods: A questionnaire was administered to all consenting guardians of children admitted to the burns (cases) and general medicine (controls) units during a period of 14 months. Guardians of patients were questioned regarding etiology of the injury, demographic and socioeconomic data. Results: 740 cases and controls were enrolled. Altogether 77.5% of the cases burns occurred in the patient's home, with 67.8% in the kitchen; 74% were due to scalding. Most involved children younger than 5 years. Lack of water supply (odds ratio (OR) 5.2, 95% confidence interval (CI) 2.1 to 12.3), low income (OR 2.8, 95% CI 2.0 to 3.9), and crowding (OR 2.5, 95%CI 1.7 to 3.6) were associated with an increased risk. The presence of a living room (OR 0.6, 95% CI 0.4 to 0.8) and better maternal education (OR 0.6, 95% CI 0.5 to 0.9) were protective factors. Conclusions: To prevent burns interventions should be directed to low socioeconomic status groups; these interventions should be designed accordingly to local risk factors.

Jouissance is a Lacanian concept, infamous for being impervious to understanding and which expresses the paradoxical satisfaction that a subject may derive from his symptom. On the basis of Freud’s “experience of satisfaction” we have proposed a first working definition of jouissance as the (benefit gained from) the motor tension underlying the action which was [once] adequate in bringing relief to the drive and, on the basis of their striking reciprocal resonances, we have proposed that central dopaminergic systems could embody the physiological architecture of Freud’s concept of the drive. We have then distinguished two constitutive axes to jouissance: one concerns the subject’s body and the other the subject’s history. Four distinctive aspects of these axes are discussed both from a metapsychological and from a neuroscience point of view. We conclude that jouissance could be described as an accumulation of body tension, fuelling for action, but continuously balancing between reward and anxiety, and both marking the physiology of the body with the history of its commemoration and arising from this inscription as a constant push to act and to repeat. Moreover, it seems that the mesolimbic accumbens dopaminergic pathway is a reasonable candidate for its underlying physiological architecture.

Several clinical case fragments show how a reading of the subject's symptoms at the level of the signifier gives access to its underlying unconscious logic. Freud's "splitting of consciousness" model is proposed to have a neurophysiologic counterpart in LeDoux's model for the processing of emotional stimuli. The language fragments in these dynamics are considered as material phoneme vectors, corresponding to Freud's word-presentation and to Lacan's signifier. Accordingly, neurolinguistic research has uncovered a specific, well-organized lexical brain area in which the words are phonologically encoded. In line with Lacan, psycholinguistic research has shown how the linguistic train always has an ambiguous structure, transiently and unconsciously activating its different meanings, followed by inhibition of the contextually inappropriate meanings. Neurophysiologic research also shows how language is always a motor event. Imminent articulatory intentions that remain without effective execution will therefore give rise to articulatory or phonemic phantoms, searching for relief in substitutive signifiers. A neurophysiologic mechanism for Freudian repression is thus proposed, leading to the return of the repressed in symptoms with a similar phonemic structure though with a radically different meaning. The phonemic phantoms thereby organize the structure of the unconscious by functioning as attractors for the subject's mental energy in its (linguistic) action space.

The dual process theory is central to several models of addiction, implying both an increase of stimulus salience and deficits in inhibitory control. Our major aim is to provide behavioral evidence for an approach bias tendency in smokers and more specifically during smoking cue exposure. The second aim is to examine whether this bias differs in low-dependent versus dependent smokers. Thirty-two smokers (17 low dependent and 15 dependent; cut-off FTND of 4) and 28 non-smokers performed a modified Go/NoGo task using tobacco-related words and neutral words as stimuli. Smokers generally made more mistakes and tended to be faster for smoking-related cues specifically. Low dependents acknowledged more their dependency in declarative questionnaires while making more errors and being slower specifically on smoking cues; dependent smokers were less prone to indicate their addiction, but were faster and accurate when it came to picking the smoking cues. These results suggest that a shift has operated from a mental preoccupation with smoking in the low-dependent group, to smoking as a motor habit in our dependent group. This finding invites experts to rethink smoking addiction in the light of this crucial moment, namely, the shift "from head to hands".
