Prospective study on prevalence, intensity, type, and therapy of acute pain in a second-level urban emergency department.

Aim: Pain represents the most frequent cause for patient admission to emergency departments (EDs). Oligoanalgesia is a common problem in this field. The aims of this study were to assess prevalence and intensity of pain in patients who visited a second-level urban ED and to evaluate the efficacy of pharmacological treatment administered subsequent to variations in pain intensity.

The evolution of social cognition: goal familiarity shapes monkeys' action understanding.

What is the evolutionary origin of the human ability to understand and predict the behavior of others? Recent studies suggest that human infants' early capacity for understanding others' goal-directed actions relies on nonmentalistic strategies [1-8]. However, there is no consensus about the nature of the mechanisms underpinning these strategies and their evolutionary history. Comparative studies can shed light on these controversial issues.
