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.

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.

Comparative Study Historical Article
Office visits and analgesic prescriptions for musculoskeletal pain in US: 1980 vs. 2000.
The treatment of pain has received increasing attention over the past decade promoted by national guidelines, the 'pain as the 5th vital sign' campaign and direct-to-consumer advertising. We examined national trends in office visits and analgesic treatment for musculoskeletal pain in the office setting, comparing data from 1980 and 2000. We analysed the National Ambulatory Medical Care Survey (NAMCS)--a nationally representative survey of visits to office-based physicians--using data from 1980-81 (n=89,000 visits) and 1999-2000 (n=45,000 visits). ⋯ This corresponds to 5.9 million visits where potent opioids were prescribed in 2000--an increase of 4.6 million visits from 1980 (assuming the total number of outpatient visits was constant at the 2000 level). In spite of the increased attention to pain treatment, there has not been an increase in office visits for musculoskeletal pain complaints. The threshold for prescribing NSAIDS and opioids, however, has dropped.

Intrathecal opioid treatment for chronic non-malignant pain: a 3-year prospective study.
Intrathecal (IT) opioid therapy is a treatment alternative for patients with severe chronic non-malignant pain. Several uncontrolled retrospective and prospective outcome studies have suggested a benefit in chronic non-malignant pain patients, but uncertainties about patient selection in these studies weaken the results. This study evaluated long-term outcome of IT opioid therapy in chronic non-malignant pain prospectively, and included two comparative groups to improve understanding of selection criteria and relative severity of intrathecal pump recipients (PRs). ⋯ These same parameters improved among new referrals (less severe patients receiving conservative pain management) while non-recipients significantly worsened. Although PRs improved, they were still worse off at 36 months than new referrals were at baseline. The study showed that when patients with extremely severe pain problems are selected as pump candidates, they will likely improve with the therapy, but their overall severity of pain and symptoms still remains high.
