Randomized Controlled Trial
Effect of topical anesthesia and age on pain scores during retinopathy of prematurity screening.
The efficacy of topical anesthesia during retinopathy of prematurity (ROP) screening has been a controversial issue. To determine the efficacy of proparacaine eye drops (0.5%), we compared the Premature Infant Pain Profile (PIPP) scores in 40 preterm infants undergoing ROP screening. ⋯ Proparacaine eye drops offer significant relief of pain that is apparently short lived. Significantly lower PIPP scores at second ROP examinations suggested that infants of older GA may have a greater ability to tolerate ROP screening. We recommend the use of proparacaine eye drops for the short term, immediate relief of pain during ROP screening in preterm infants of lesser GA.

Randomized Controlled Trial
Effect of a symptom diary on symptom frequency and intensity in healthy subjects.
Symptom and pain diaries are often recommended to or used by patients with chronic pain disorders. Our objective was to examine the effect on recall of symptoms after 14 days of daily symptom diary use in healthy subjects. ⋯ The use of a symptom diary for 2 weeks, even in generally healthy subjects, results in increased recall of daily symptoms and increased perception of symptom severity.

Randomized Controlled TrialReliability, construct validity, and responsiveness of the neck disability index, patient-specific functional scale, and numeric pain rating scale in patients with cervical radiculopathy.
To examine the psychometric properties of the Neck Disability Index, Patient-Specific Functional Scale, and the Numeric Pain Rating Scale in a cohort of patients with cervical radiculopathy. ⋯ In light of the varied distribution of symptoms in patients with cervical radiculopathy, future studies should investigate the psychometric properties of other neck-related disability measures in this patient population.

Randomized Controlled Trial
Development and longitudinal validation of the overall benefit of analgesia score: a simple multi-dimensional quality assessment instrument.
The goal of this study was to develop and validate the overall benefit of analgesic score (OBAS), which assesses pain intensity and the opioid-related adverse effects. ⋯ The OBAS is a simple, multi-dimensional quality assessment instrument to measure patients' benefit from postoperative pain therapy. Opioid symptom distress, pain relief, and patients' satisfaction are combined in a reliable and valid tool.

Randomized Controlled Trial Comparative Study
Insular cortex activity is associated with effects of negative expectation on nociceptive long-term habituation.
It is generally accepted that acute painful experience is influenced by context information shaping expectation and modulating attention, arousal, stress, and mood. However, little is known about the nature, duration, and extent of this effect, particularly regarding the negative expectation. We used a standardized longitudinal pain paradigm and painful heat test stimuli in healthy participants over a time course of 8 consecutive days, inducing nociceptive habituation over time. ⋯ Functional imaging data showed a difference between the two groups in the right parietal operculum. These data suggest that a negative context not only has an effect on immediate pain but can modulate perception of pain in the future even without experience/conditioning. Neuronally, this process is mediated by the right opercular region.
