An attempt has been made to examine types and style of leadership, but also expectations from them. Perhaps an ability to influence others is one of key determinants of leadership.

To be able to do that, in addition to the fittings, light and general ambience, a future design of such a facility must consider how consumers are likely to access mental healthcare in the future, what aspects of care they are likely to find value-adding and how the inpatient aspect of their care is likely to be integrated within their care continuum. Conclusions The future design must anticipate how consumers are likely to access information, support, care and treatment, how workflows of staff are likely to change, how the diverse needs of mental health consumers will need to be accommodated and how the needs and expectations of staff will be met to enable them to provide support to mental health consumers. A future design of a mental health inpatient unit may have to be very different from the current thinking about the desig...

This resulted in spontaneous resolution of symptoms of depression. The resolution of intrapsychic conflict as a result of development of Ganser syndrome which led to sudden remission of major depressive episode is discussed.

Eight healthy male volunteers participated in four weekly sessions. Each session was associated with one of the following treatments: placebo (physiological saline infused intravenously over 10 min) at 20 degrees C; clonidine hydrochloride (1.5 micrograms kg-1 in 10 ml infused intravenously over 10 min) at 20 degrees C; placebo at 40 degrees C; clonidine at 40 degrees C. Subjects were allocated to treatments and sessions according to a double-blind (for drug condition) balanced design. In each session, the following indices of autonomic function were recorded: systolic and diastolic blood pressure, heart rate, salivation, body temperature, plasma noradrenaline and adrenaline concentrations, baseline and carbachol-evoked sweating, physiological finger tremor. Raised ambient temperature (40 degrees C) caused increases in heart rate, body temperature, carbachol-evoked sweating and physiological finger tremor. Clonidine (at 20 degrees C) reduced systolic blood pressure, body temperature, salivation and plasma noradrenaline concentration, but did not affect any of the other measures. Clonidine (at 40 degrees C) counteracted the increase in heart rate, but not the increases in carbachol-evoked sweating and finger tremor, evoked by high ambient temperature. The high ambient temperature condition abolished the body-temperature-lowering effect of clonidine, but did not modify the effects of clonidine on systolic blood pressure, salivation and plasma noradrenaline concentration. These result indicate that while the effects of the heat stressor are consistent with an increase in sympathetic activity, and most of the effects of clonidine are consistent with a decrease in sympathetic activity, only two functions (body temperature and heart rate) were affected in opposite directions by the two interventions. Indeed physiological antagonism between the two interventions could be demonstrated on body temperature and heart rate only, and there was no evidence for an interaction between the effects of the two variables on any of the other indices of autonomic activity. The failure of clonidine to affect two sympathetically mediated functions, carbachol-evoked sweating and physiological finger tremor, under either temperature condition, indicates that central alpha 2-adrenoceptors cannot be involved in the regulation of these functions.

Method Computerised literature searches were used to identify reports on extrapyramidal symptoms and serotonin reuptake inhibitors. Subsequently, manual searches were made for articles in which there was any indication of the mechanisms responsible for these extrapyramidal symptoms. Results Only a few reports could be identified in which serotonin reuptake inhibitors were implicated in extrapyramidal symptoms in some patients. Conclusions Evidence is discussed from preclinical and clinical studies suggesting the interaction between serotoninergic and dopaminergic neurotransmitter system, as a possible mechanism for production of extrapyramidal symptoms.
