Pain relief after laparoscopic cholecystectomy (LC) is an issue of great practical importance. Pain after LC has several origins: incisional, local visceral, peritoneal, and referred. Several modalities have been employed for achieving effective and safe analgesia: nonsteroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase-2 (COX-2) inhibitors, gabapentinoids, local anesthetics, and transversus abdominis plane (TAP) block. ⋯ Factors enhancing the effectiveness of these agents include early instillation before creating the pneumoperitoneum, larger volume of medium used for instillation, and favorable pharmacological characteristics of the agent. Combination of LA with either NSAID/COX-2 inhibitors or fibrin sealant appears to be effective, although more research is required for determining the exact combinations and efficacy using direct comparisons with single-modality interventions. Finally, newer procedures such as TAP block appear promising if replicated.

Retrospective cohort study. ⋯ Nonmechanical findings during a traditional movement screen are not specific to sinister conditions such as metastatic spinal cancer. Clinicians should expect concomitant conditions to exhibit painful or limited findings in patients with and without cancer.

Randomized Controlled Trial Multicenter Study
Successful dose finding with sublingual fentanyl tablet: combined results from 2 open-label titration studies.
This analysis was conducted to determine the likelihood of identifying an effective dose of fentanyl sublingual tablet during the initial titration phase of 2 clinical trials, to characterize the actual effective dose in patients achieving successful titration, and to examine the relationship between baseline characteristics and likelihood of achieving an effective dose. ⋯ Despite stringent criteria, 64.4% of patients achieved an effective dose of fentanyl sublingual tablet within the dose range of 100 to 800 μg. Baseline characteristics were not identified to be associated with the likelihood of successful titration or with the actual effective dose of fentanyl sublingual tablet.

Case Reports
Modulation of somatosensory profiles by spinal cord stimulation in primary Raynaud's syndrome.
Spinal cord stimulation (SCS) is an effective antinociceptive treatment for various neuropathic pain syndromes. Apart from antinociceptive action, it may modulate overall somatosensory perception. This case report targets the question of whether SCS may alter quantitative sensory testing (QST) in a patient with primary Raynaud's syndrome. ⋯ SCS significantly modulated the somatosensory profile in a patient with primary Raynaud's syndrome. These effects were pronounced in qualities involving Aβ, C, and A∂ nerve fibers. Further investigations may help to understand the mechanisms of action of SCS.
