Eye Direction Detection and Perception as Premises of a Social Brain: A Narrative Review of Behavioral and Neural Data.

The eyes and the gaze are important stimuli for social interaction in humans. Impaired recognition of facial identity, facial emotions, and inference of the intentions of others may result from difficulties in extracting information relevant to the eye region, mainly the direction of gaze. Therefore, a review of these data is of interest.

Misuse of opioid analgesics in elderly patients: a review.

Opioid analgesic (OA) addiction occurs frequently among the elderly, and results in high morbidity and mortality due to geriatric pathologies associated with pharmacokinetic modifications. However, patients with this type of addiction are under-identified and specific screening tools should be more widely used to detect the risk factors for OA addiction. Before initiating an opioid prescription, exhaustive research into associated treatments (to track drug interaction) and opioid prescriptions by other clinicians (a phenomenon known as "doctor shopping") is required.

[Analgesic opioids misuse in the elderly: A review].

Analgesic opioids addiction (AOA) is very frequent in the elderly, and results in a high morbi-mortality due to geriatric associated pathologies with pharmacokinetics modifications. However, it is poorly detected in these subjects and specific screening tools should be widely used to detect the risk factors for AOA prevention. Before initiating opioid prescription, exhaustive search of associated treatments (to track drug interaction) and of opioid prescription by other clinicians (doctor shopping) are requisite.
