Randomized Controlled Trial
A Randomized Controlled Comparison of Epidural Analgesia Onset Time and Adverse Reactions During Labor with Different dose Combinations of Bupivacaine and Sufentanil.
The purpose was to compare the effects of 3 different dose combinations of bupivacaine and sufentanil on the onset of analgesia and the occurrence of side effects. ⋯ The B125S5 combination may be superior to the B1S5 and B1S10 combinations as an initial dose for epidural analgesia to achieve rapid effective analgesia with minimal side effects.

Dexmedetomidine 2▒ppm is Appropriate for the Enhancement Effect of Local Anesthetic Action of Lidocaine in Inferior Alveolar Nerve Block: A Randomized Crossover Study; A Study that Awaits Confirmation in a Larger Trial.
Local anesthesia is essential for pain management in dentistry. The duration of anesthetic action of the addition of 5.0 and 7.5 ppm of dexmedetomidine (DEX) was significantly longer than the addition of adrenaline, and the mean duration of anesthetic action of the addition of 2.5 ppm DEX was also longer than the addition of adrenaline. We hypothesized that it is possible to safely achieve an equal local anesthesia effect as with 1:80,000 adrenaline, without using adrenaline or felypressin, by the addition of <2.5 ppm DEX to the local anesthetic solution. ⋯ DEX at a concentration of 1.0 to 2.0 ppm enhances the local anesthetic action of lidocaine. DEX at 2.0 ppm produces similar enhancement of local anesthesia effect as the addition of 1:80,000 adrenaline.

Pressure Pain Tolerance Predicts the Success of Emotional Awareness and Expression Therapy in Patients with Fibromyalgia.
Quantitative sensory testing may help predict treatment responses in individuals with chronic pain. Our objective was to determine whether evoked pain sensitivity at baseline predicted preferential treatment responses to either emotional awareness and expression therapy (EAET) or cognitive behavioral therapy (CBT) in individuals with fibromyalgia (FM). ⋯ Normal levels of pressure pain tolerance at baseline predicted greater improvement in clinical pain severity after EAET than CBT. Quantitative sensory testing may provide insights about individual responses to psychologically based therapies for individuals with chronic pain.

Efficacy and Safety of Single and Multiple Doses of a Fixed-dose Combination of Ibuprofen and Acetaminophen in the Treatment of Postsurgical Dental Pain: Results from Two Phase 3, Randomized, Parallel-Group, Double-Blind, Placebo-Controlled Studies.
A previous pilot study demonstrated that various fixed-dose combinations (FDCs) of ibuprofen (IBU) and acetaminophen (APAP) provided analgesic efficacy comparable to a higher dose of IBU, with the same safety profile. These studies further evaluated the chosen FDC IBU/APAP 250/500 mg formulation. ⋯ FDC IBU/APAP 250/500 mg provides superior analgesic efficacy to individual monocomponents (IBU 250 mg and APAP 650 mg), a rapid onset of action, >8-hour duration of pain relief, is generally well tolerated, and may provide an additional nonopioid treatment option for acute pain.

Defining Recovery in Chronic Whiplash: A Qualitative Study.
The meaning of recovery from musculoskeletal injury is complex, and understanding recovery from whiplash may be particularly important, given the chronic, often recalcitrant nature of the condition. Gaining a better understanding of recovery may also aid in the development and interpretation of future clinical trials. The aim of this study was to define the meaning of recovery from whiplash, and the factors influencing recovery, by exploring the perceptions of people with chronic whiplash, and their treating physiotherapists. ⋯ Recovery is a multidimensional and complex construct. In addition to pain intensity and disability, measurement and conceptualization of recovery should focus on emotional well-being, self-perception, and the cultural values and beliefs of the individual. A positive therapeutic relationship, with attention to psychological and social influences, appears to be important in facilitating recovery and well-being.
