Randomized Controlled Trial Comparative Study Clinical Trial
A double-blind placebo-controlled comparison of tramadol/acetaminophen and tramadol in patients with postoperative dental pain.
The objective of this study was to compare the analgesic efficacy of tramadol/acetaminophen (APAP) (total dose 75 mg/650 mg) and tramadol (total dose 100 mg) for the control of pain after oral surgery. A total of 456 patients with moderate-to-severe pain within 5 h after extraction of two or more third molars were randomized to receive two identical encapsulated tablets containing tramadol/APAP 37.5 mg/325 mg, tramadol 50 mg, or placebo. ⋯ The most common adverse events with active treatment were nausea, dizziness, and vomiting; these events occurred more frequently in the tramadol group than in the tramadol/APAP group. This study established the superiority of tramadol/APAP 75 mg/650 mg over tramadol 100 mg in the treatment of acute pain following oral surgery.

Single-dose clinical trial methods for evaluating analgesics have been used successfully for over 50 years. The aims of this review were to examine which pain measurement scales have been used in high quality acute pain trials, to investigate other common measurements or characteristics, to confirm that different scales used by standard methods give the same estimate of analgesic effect, to investigate remedication methodologies and the potential of 'time to remedication' as a standard outcome. Published reports of randomised, double blind, placebo-controlled trials, investigating at least 20 adult patients (10 patients per treatment arm) experiencing moderate or severe pain using at least one standard pain intensity or pain relief scale were sought. ⋯ Possible improvements include reporting the number of patients with certain levels of pain relief, or the actual number (percentage) of patients with a certain level of pain relief at a certain time, or more useful information on remedication from trials of at least 12 h duration. Most useful would be all three. Further exploration would only be possible from analysis at the individual patient level.

Shoulder complaints are common and have an unfavourable outcome in many patients. Only 50% of all new episodes of shoulder disorders end in complete recovery within 6 months. There is no consensus about prognostic indicators that can identify patients at high and low risk of chronicity. ⋯ There is strong evidence that high pain intensity predicts a poorer outcome in primary care populations and that middle age (45-54) is associated with poor outcome in occupational populations. There is moderate evidence that a long duration of complaints, and high disability score at baseline predict a poorer outcome in primary care. These results need to be interpreted with caution because of the small number of studies on which these conclusions are based, and the large heterogeneity among studies regarding follow-up, outcome measures, and analysis.

Randomized Controlled Trial Clinical Trial
Effect of acupuncture treatment on chronic neck and shoulder pain in sedentary female workers: a 6-month and 3-year follow-up study.
The study was carried out to examine whether acupuncture treatment can reduce chronic pain in the neck and shoulders and related headache, and also to examine whether possible effects are long-lasting. Therefore, 24 female office workers (47+/-9 years old, mean+/-SD) who had had neck and shoulder pain for 12+/-9 years were randomly assigned to a test group (TG) or a control group (CG). Acupuncture was applied 10 times during 3-4 weeks either at presumed anti-pain acupoints (TG) or at placebo-points (CG). ⋯ Three years after the treatments TG still reported less pain than before the treatments (Pw < 0.001) contrary to what CG did (Pb < 0.04) The degree of headache fell during the treatment period for both groups, but more for TG than for CG (Pb=0.02) Three years after the treatments the effect still lasted for TG (Pw < 0.01) while the degree of headache for CG was back to the pre-treatment level (Pb < 0.001) PPT of some muscles rose during the treatments for TG and remained higher 6 months after the treatments (Pw < 0.05) which contrasts the situation for CG. Adequate acupuncture treatment may reduce chronic pain in the neck and shoulders and related headache. The effect lasted for 3 years.

Recurrent pain in childhood are common and frequently impact children's everyday functioning. However, there are currently limited tools available to measure the impact of recurrent pain on children's daily activities, in particular, that can be used to identify appropriate targets for intervention and measure response to such interventions. The purpose of this study was to develop and validate a new measure, the Child Activity Limitations Interview (CALI), to improve the assessment of functional impairment due to recurrent pain in school-age children and adolescents, and to compare this measure to the Functional Disability Inventory. ⋯ One-month test-retest reliability (r = 0.33, child report) and cross-informant reliability (r = 0.43) were moderate. Results demonstrate support for face, construct, and concurrent validity as well as responsiveness to pain symptom fluctuation. Findings demonstrate that the CALI is a promising measure for assessing and monitoring subjective report of functional impairment in school-age children and adolescents with recurrent and chronic pain.
