Staff in the emergency departments of hospitals are reported as being negative or ambivalent toward suicidal or self-harming individuals. According to the literature, these patients are subjected to stigmatization and lack of empathy. This phenomenon has been linked to a decreased quality of care offered to these individuals and to missing an important opportunity to prevent further suicidal behavior or repetition of deliberate self-harm. Also, protocols, proper guidelines and education for the emergency staff call for a revision and an implementation. In this paper, evidence suggesting staff attitudes toward suicidal and self-harming patients is reviewed. An overview of related issues such as clinical judgment, the use of scales and nurses' role is also included in this report.

Several studies suggested the neural networks modulating aspects of emotional behaviour to be implicated in the pathophysiology of mood disorders. These networks involve the medial prefrontal cortex (MPFC) and closely related areas in the medial and caudolateral orbital cortex (medial prefrontal network), amygdala, hippocampus, and ventromedial parts of the basal ganglia, where alterations in grey matter volume and neurophysiological activity are found in cases with recurrent depressive episodes. Such findings hold major implications for models of the neurocircuits that underlie depression. In particular, evidence from lesion analysis studies suggests that MPFC and related limbic and striato-pallido-thalamic structures organize emotional expression. The aim of this paper is to review the contribution of the most relevant studies with single photon emission tomography (SPECT), positron emission tomography (PET) and magnetic resonance imaging (MRI) to the understanding of pathophysiology of major depressive disorder (MDD), with particular focus on the reversibility of functional correlates with treatment.

Reports of self-enucleation are frequent in medical literature, but cases of enucleation towards another are rare.We report the case of a man, 20 years of age, who suffered from psychosis with hydrocephalus and aqueductal stenosis that required a forensic psychiatric investigation to ascertain whether he was of unsound mind when he assaulted and enucleated the right eye of an officer and led to the surgical enucleation of the victim's left eye. Based on his clinical interviews and hospitalization record, we conclude that at the time of the assault, he was suffering from a delusional disorder with religious and demonic content, visual and auditory hallucinations, illusion phenomena, delusional interpretations, imaginative elements, a feeling of terror, and command hallucinations that compelled him to perform the act of aggression.

The identification of mixed features during a major depressive episode is important due to the worse course and treatment issues associated with this condition. Diagnostic and Statistical Manual of Mental Disorders Fifth Edition mixed features specifier criteria are controversial, because it includes typical manic symptoms, whereas it excludes overlapping excitatory symptoms that are frequently reported in mixed depression. Psychomotor agitation, mood lability, and aggressiveness are the new proposed criteria based on the results of the Bipolar Disorders: Improving Diagnosis, Guidance and Education-II-Mix study. Several clinical and course indicators of bipolarity were found to be associated with the presence of mixed characteristics, mainly overlapping excitatory symptoms, during a major depressive episode.
