Randomized Controlled Trial
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.

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.

Comparison of Adductor Canal Block and Femoral Triangle Block for Total Knee Arthroplasty.
Adductor canal block (ACB) could provide effective postoperative pain control for patients after total knee arthroplasty (TKA). However, some authors pointed out that the ACB as originally described may be more similar to a femoral triangle block (FTB). Recent neuroanatomic evidences made the authors conjecture that the "true" ACB would provide superior analgesia compared with FTB. Therefore, the study was designed to determine the hypothesis that postoperative analgesia after TKA could be improved by a "true" ACB compared with FTB. ⋯ ACB can provide superior analgesia and preserve more quadriceps strength than FTB. ACB facilitates functional recovery in the early stages and is compatible with the highly recognized concept of rapid rehabilitation, which should be promoted in the clinic.

The current study assessed the role of hypervigilance for bodily sensations in the back in long-term low back pain problems. ⋯ The current study confirmed that individuals preparing a movement attended more toward somatosensory stimuli at the lower back when anticipating back pain during the movement, as measured by the N96 SEP. However, no differences were found between participants with chronic low back pain or recurrent low back pain, or the pain-free controls.

This study aimed to develop a method that objectively measures the clinical benefits of ketamine infusions to treat complex regional pain syndrome (CRPS), thus making it possible, for the first time, to determine the optimal dosing of ketamine and duration of treatment to treat CRPS. ⋯ Our findings suggest that 4 days of treatment are sufficient for the treatment of CRPS of the lower extremities. For the upper extremities, >4 days may be required. Our study is the first to utilize quantitative sensory testing to direct the treatment of a chronic pain disorder.
