Facial transplantation: adding to the reconstructive options after severe facial injury and disease

The ability to reconstruct complex facial injuries is still a considerable challenge despite the development of microsurgical techniques. The reconstructive options for conditions such as panfacial burns are severely limited. The result after multiple surgical procedures in this group is often poor in terms of function and cosmesis. Facial transplantation provides a potential solution, but opinion is currently divided about the extent to which the potential benefits to the quality of life can be justified when weighed against the technical, psychological and immunological risks. This paper reviews the current status of the debate and argues that a rigorous research strategy is the only logical basis for countering the ethical objections to a procedure that offers considerable benefits over existing reconstructive options.     

Functional connectivity between amygdala and facial regions involved in recognition of facial threat

The recognition of threatening faces is important for making social judgments. For example, threatening facial features of defendants could affect the decisions of jurors during a trial. Previous neuroimaging studies using faces of members of the general public have identified a pivotal role of the amygdala in perceiving threat. This functional magnetic resonance imaging study used face photographs of male prisoners who had been convicted of first-degree murder (MUR) as threatening facial stimuli. We compared the subjective ratings of MUR faces with those of control (CON) faces and examined how they were related to brain activation, particularly, the modulation of the functional connectivity between the amygdala and other brain regions. The MUR faces were perceived to be more threatening than the CON faces. The bilateral amygdala was shown to respond to both MUR and CON faces, but subtraction analysis revealed no significant difference between the two. Functional connectivity analysis indicated that the extent of connectivity between the left amygdala and the face-related regions (i.e. the superior temporal sulcus, inferior temporal gyrus and fusiform gyrus) was correlated with the subjective threat rating for the faces. We have demonstrated that the functional connectivity is modulated by vigilance for threatening facial features.     

Intuition from Beginning to End? Bion's Clinical Approaches

This paper is intended to offer a foundation for comparison of the approaches of Wilfred Bion and Donald Winnicott. In particular, I try to plot the oscillation of Bion's clinical method from his early Group period at the Tavistock Clinic (up to around 1950) when he emphasized countertransference; his part‐object interpretation method in the 1950s after his analysis with Klein when he and colleagues were experimenting with the psychoanalysis of people in psychotic states (1953–59); and then his return to his investigation of the intuitive approach to clinical data, around 1965–70.
