Randomized Controlled Trial
γ-Aminobutyric acid (GABA) oral rinse reduces capsaicin-induced burning mouth pain sensation: An experimental quantitative sensory testing study in healthy subjects.
In burning mouth patients, analgesia after oral administration of clonazepam may result from modulation of peripheral γ-aminobutyric acid (GABA) receptors. ⋯ Rinsing the mouth with an oral GABA containing solution ameliorated burning pain and increased heat sensitivity produced by application of capsaicin to the tongue. This finding suggests that GABA can act as a local analgesic agent in the oral cavity.

Randomized Controlled Trial
Efficacy and safety of a fixed-dose combination of ibuprofen and caffeine in the management of moderate to severe dental pain after third molar extraction.
Ibuprofen is an effective analgesic treatment with a ceiling effect at doses above 400 mg. This study compared the combination of ibuprofen 400 mg and caffeine 100 mg with ibuprofen 400 mg monotherapy, caffeine and placebo in the analgesic treatment of moderate to severe acute dental pain following third molar extraction. ⋯ This trial showed superior efficacy of 400/100 mg ibuprofen/caffeine, compared to 400 mg ibuprofen alone, for treating acute pain, reflecting that caffeine is an effective analgesic adjuvant. Data on efficacy of 400 mg ibuprofen combined with caffeine for the treatment of acute pain were not available yet.

Randomized Controlled Trial
Equimolar mixture of nitroux oxyde and oxygen during post-operative physiotherapy in patients with cerebral palsy: A randomized, double-blind, placebo-controlled study.
The administration of an equimolar mixture of nitrous oxide and oxygen (N2O) is recommended during painful procedures. However, the evaluation of its use during physiotherapy after surgery has not been reported, although pain may hamper physiotherapy efficiency. This study investigated whether the use of N2O improves the efficacy of post-operative physiotherapy after multilevel surgery in patients with cerebral palsy. ⋯ During this randomized placebo-controlled double-blind study, children receiving nitrous oxide and oxygen (N2O) achieved more often the targeted range of motion during physiotherapy sessions after multilevel surgery. Compared to placebo, nitrous oxide and oxygen (N2O) enabled a better management of acute pain related to physiotherapy procedures.

Randomized Controlled Trial
Visually induced analgesia during massage treatment in chronic back pain patients.
Previous findings suggest that watching sites of experimental and chronic pain can exert an analgesic effect. Our present study investigates whether watching one's back during massage increases the analgesic effect of this treatment in chronic back pain patients. ⋯ This study shows that inducing visual induced analgesia during massage treatment can be helpful in alleviating chronic pain.

Randomized Controlled Trial
Testing the validity of telephone interviews to assess chronic pain in children and adolescents: A randomized cross-over trial.
Telephone surveys are intended to reduce attrition in longitudinal studies. For paediatric chronic pain patients, the comparability of pain-related information gathered using telephone interviews and postal surveys remain unknown. Furthermore, it remains unknown how social desirability may influence answers. ⋯ Telephone interviews are a good method to achieve a high response rate and obtain valid data in studies with paediatric chronic pain patients.
