Randomized Controlled Trial
Stimulation of myofascial trigger points with ultrasound induces segmental antinociceptive effects: a randomized controlled study.
Musculoskeletal pain affects a significant proportion of the general population. The myofascial trigger point is recognized as a key factor in the pathophysiology of musculoskeletal pain. Ultrasound is commonly employed in the treatment and management of soft tissue pain and, in this study, we set out to investigate the segmental antinociceptive effect of ultrasound. ⋯ Following the ultrasound intervention, PPT readings were recorded at 1, 3, 5, 10 and 15 min intervals at both infraspinatus and gluteus medius trigger points; the difference between infraspinatus and gluteus medius PPT values, PPT seg, represents the segmental influence on the PPT. The ultrasound test group demonstrated statistically significant increases in PPT seg (decreased infraspinatus sensitivity) at 1, 3 and 5 min, when compared with PPT seg in the sham ultrasound group. These results establish that low-dose ultrasound evokes short-term segmental antinociceptive effects on trigger points which may have applications in the management of musculoskeletal pain.

Randomized Controlled Trial Comparative Study
Social influence and pain response in women and men.
The purpose of this study was to examine the effects of social influence on responses to acute pain in women and men in a randomized experimental design. Sixty-eight undergraduates (32 women; 36 men) were randomly assigned to perform a cold pressor task either alone or in the presence of a same-sex friend. Expressions of pain were assessed with the short form of the McGill Pain Questionnaire. ⋯ Persons who reported high levels of social support on the Krause scale also reported greater cold pressor pain. Results suggest that the presence of a friend can increase pain report to an acute laboratory pain stimulus in women. These findings are consistent with models of social reinforcement in chronic pain syndromes.

Facial pain: a possible therapy with stellate ganglion block.
The goal of the present study is to verify the efficacy of stellate ganglion block (SGB) in the treatment of facial pain that can be found in different pathological syndromes, and also to examine whether the efficacy is dependent upon when this therapy is administered. ⋯ Our results indicate that patients must be treated with SGB therapy precociously to receive its full benefits.

Randomized Controlled Trial Comparative Study
Evaluation of analgesic effect of skin-to-skin contact compared to oral glucose in preterm neonates.
Nonpharmacological interventions are important alternatives for pain relief during minor procedures in preterm neonates. Skin-to-skin contact or kangaroo mother care is a human and efficient way of caring for low-weight preterm neonates. The aim of the present study was to assess the analgesic effect of kangaroo care compared to oral glucose on the response of healthy preterm neonates to a low-intensity acute painful stimulus. ⋯ In group 3 (glucose, n=31), the neonate was in the prone position in the isolette and received oral glucose (1 ml, 25%) 2 min before heel lancing. A smaller variation in heart rate (p=0.0001) and oxygen saturation (p=0.0012), a shorter duration of facial activity (brow bulge, eye squeeze and nasolabial furrowing) (p=0.0001), and a lower PIPP (Premature Infant Pain Profile) score (p=0.0001) were observed in group 2. In conclusion, skin-to-skin contact produced an analgesic effect in preterm newborns during heel lancing.

Randomized Controlled Trial Comparative Study
Observational pain assessment versus self-report in paediatric triage.
To examine if observational pain assessment can be used for purposes of triage in children aged >3 years. ⋯ Observational pain assessment underestimates children's perception of pain and should not be recommended in children aged >3 years. Triage has a calming effect on children.
