Limited evidence is available about factors influencing observers' anticipatory emotional responses to another's pain. We investigated fear and distress towards the threat of pain in others, and the moderating role of observers' psychopathic traits and catastrophizing about their own or others' pain. Thirty-six dyads of healthy participants were randomly assigned to either the role of observer or observed participant. Both participants were instructed that 1 colored slide (blue or yellow) signalled that a pain stimulus could possibly be delivered to the observed participant (=pain signal), whereas no pain stimulus would be delivered when a differently colored slide was presented (=safety signal). Observers' self-reported fear, fear-potentiated startle, and corrugator electromyography activity during pain and safety signals were measured. Furthermore, observers rated the presence of pain after each trial allowing assessment of observers' perceptual sensitivity to others' pain. Results indicated that self-reported fear, fear-potentiated startle, and corrugator electromyography activity were augmented during pain signals compared to safety signals. Moreover, these negative emotional responses were heightened in observers highly catastrophizing about others' pain, but reduced in observers with heightened psychopathic traits. Psychopathic traits were also related with a diminished perceptual sensitivity to others' pain. The results are discussed in light of affective-motivational perspectives on pain. PERSPECTIVE: This study investigated observers' negative emotional responses in anticipation of pain in another, and the moderating role of observers' psychopathic traits and pain catastrophizing. Knowledge about characteristics influencing observers' emotional response to others' pain may provide insight into why observers engage in particular behaviors when faced with another in pain.

Little is known about how a child's experience of pain affects his or her parents. Using a vignette methodology, this study investigated the emotional responses of parents who were asked to imagine different painful situations that their child might experience. A sample of 650 parents of school children (325 mothers; 325 fathers) read 8 short stories/vignettes about their child, which varied in terms of type of situation (pain vs other stressful situation), intensity (high vs low), and frequency of occurrence (high vs low). The role of individual differences in parental catastrophizing about their child's pain, catastrophizing about their own pain, dispositional empathy, and gender was also investigated. Parents' dispositional empathy was found to have an impact on parental distress and concern for their child. Catastrophizing about their child's pain had a unique contribution to parents' emotional responses to the vignettes describing their child in pain, beyond the influence of other variables. The impact of parental catastrophizing about their child's pain was most pronounced for parental distress, probably reflecting the high threat value that they attribute to their child's pain. The findings are discussed within recent models of empathy and pain, delineating possible relationships with parents' behavioral responses to their child's pain. PERSPECTIVE: This vignette study found preliminary evidence for the importance of parent characteristics, beyond situational characteristics, in parental emotional responses to their child's pain. The findings provide indications for the processes implied in parental helping behavior. [ABSTRACT FROM AUTHOR]

Fear of blood, injections, and needles commonly prevents or delays individuals’ receipt of health care, such as vaccines or blood draws. Innovative methods are needed to overcome these fears and reduce anxiety related to activities of this nature. The present study describes initial testing of an arm illusion paradigm that may prove useful during early phases of graded exposure for people with blood and needle fear. Seventy-four undergraduate students aged 18–29 years were tested. In line with study aims, results indicated that the virtual blood draw paradigm promoted strong perceptions of arm ownership and elicited significant changes in physiological indices (blood pressure, heart rate, electrodermal activity, respiratory rate) in response to key procedure elements (e.g., needle insertion). Further, bivariate correlations indicated that individual differences in self-reported blood and needle fear collected prior to the illusion paradigm were significantly associated with presyncopal symptoms reported following the procedure. In regression analyses, self-reported measures of blood and needle fear explained unique variance in presyncopal symptoms even after controlling for general state anxiety. These findings provide initial support for the virtual blood draw paradigm as a promising tool to help provide graded exposure to medical procedures involving needles and blood draw.

Abstract: The intramedullary nailing of humerus has emerged as one of the treatments of reference for proximal fractures. We have reviewed 38 patients aged 64.2 on average with a mean follow of 18 months. The functional scores used were the Constant and Murley''s score as well as the DASH self-administered quality of life questionnaire. Radiological criteria have been analyzed, namely the cephalic angle noted αF and the presence of any osteolysis of the major tuberosity. Patients were grouped by type of fracture, according to Neer''s classification, with nine cases in Neer 2 group, 19 in Neer 3 group, and ten in Neer 4 group. The unrefined Constant score was 53.4 points on average, balanced to 71.6%. The joint mobilities were an average forward elevation of 108°, an average abduction of 100° and an external rotation of 27°. These scores were even worse than the fracture was comminuted. It was not found a radioclinical correlation between value of the angle αF and clinical outcome, but the presence of osteolysis of the major tuberosity was significantly associated with poor late functional results. Five cases of osteonecrosis have been counted, divided with 10.5% in the Neer stage 3, and 30% in the Neer stage 4. The average unrefined Constant score from these patients was 38.5 points on average, balanced to 57.7%. Intramedullary nailing allows fixation of comminuted fractures with three or four fragments, but control of fixing and strength of assembly were not always practiced. In young patients, where tuberosities consolidation is essential, screwed plates seem to be a favorable alternative. Moreover, total reverse prosthesis seems to have more and more arguments to impose itself like the preferred treatment towards fractures in four fragments in people aged over 75 years.
