Comparative Study
Rheumatoid arthritis: determination of pain characteristics and comparison of RAI and VAS in its measurement.
The purposes of this study were to determine pain characteristics in female patients with rheumatoid arthritis (RA) and to determine the relationship between the outcome of the Ritchie Articular Index (RAI) and pain intensity as measured by the visual analogue scale (VAS). The sample consisted of 30 female patients with a definite diagnosis of RA and a functional capacity of class II. The results indicated that the pain fluctuated during the day. ⋯ A high correlation r = 0.86 (P less than 0.01) was found between the scores of RAI and present pain on the VAS. This finding suggests that the pain in RA is associated with the hyperalgesic state induced by the inflammatory condition associated with RA. There was no significant correlation between blood tests like ERS, WBC and VAS or RAI.

Randomized Controlled Trial Comparative Study Clinical Trial
[Critical aspects of an outside evaluation of postoperative pain in infants. A placebo-controlled double-blind study of the question of the reliability and validity of the measurement system].
Postoperative analgesia in infants and young children is a topic of growing interest in pediatric anesthesia. Two systems measuring postoperative pain in this group of patients have been offered recently: CHEOPS (Childrens Hospital of Eastern Ontario Pain Scale) by McGrath et al. and OPS (Objective Pain Scale) by Hannallah et al. and Broadman et al. [3, 7, 8]. Both systems are economical and not reactive, but their validity is not satisfying. ⋯ The design of the study was accepted by the ethic committee with the provision that neither a sedative nor an analgesic drug should be withheld from any child if indicated. Therefore, all children who seemed to feel discomfort according to the subjective impression of the anesthetist received midazolam intraveneously to a maximal dose of 2 mg. All the behavioral data were included in a factor analysis (principal components)...

Musculoskeletal disorders of the stomatognathic system comprise the majority of diagnoses responsible for chronic orofacial pain. The most common signs for these disorders include tenderness, limitation in range of motion, deviation in range of motion, and joint noise. Although these signs are used routinely for diagnosis, the reliability, validity, and accuracy of their use as diagnostic criteria or outcome measures has not been established. ⋯ Both tenderness and dysfunction improved with treatment but did not become normal. The percent agreement of these signs as diagnostic criteria for the presence and stage of a temperomandibular joint (TMJ) internal derangement was about 80% compared with arthrotomography. These studies suggest that these clinical characteristics can be used with adequate reliability and validity to diagnose and measure severity if standardized methods are used.

Comparative Study[Changes in the RIII response of the flexion reflex with painful maneuvers].
In the search for reliable indirect indices of pain sensation, interest has recently focused on the nociceptive flexion reflex and late components of the brain evoked potentials. In ten volunteers with sciatica, the nociceptive flexion reflex (RIII) and the late component (N150-P220) of the evoked potentials were recorded, with the subjects at rest and during pain produced by the Lasegue manoeuvre. ⋯ In contrast, the amplitude of the N150-P220 components did not change significantly. Our results indicate that, of the two parameters tested, RIII alone is a reliable index for measuring pain sensation.

In order to provide burn patients with adequate pain relief, the nurses must be able to accurately evaluate the patients' pain levels and to assess whether sufficient analgesia is achieved or not. The present study examined this issue by comparing the pain ratings in 42 patients hospitalized for burn injuries and 42 nurses. The patient and the attending nurse were asked to rate, independently of each other, the intensity of the pain felt by the patient during a therapeutic procedure and at rest. ⋯ However, the number of years of experience in burn-nursing had a significant influence on the nurses' estimation of the patients' pain during therapeutic procedures. Theoretical and clinical implications of these results are discussed with a particular emphasis on the need to implement systematic procedures to assess pain and success of analgesia. Additional recommendations to optimize pain management in burn patients are also made.
