Low back pain is a common and expensive health complaint. Many low back pain trials have been conducted, but these are reported in a variety of ways and are often difficult to interpret. ⋯ A group of back pain experts reached a high level of consensus on a statement recommending reporting methods for patient-reported outcomes in future low back pain trials. The statement has the potential to increase interpretability and improve patient care.

Randomized Controlled Trial
Effect of morphine in needle procedures in children with cancer.
The aim was to investigate whether children experience less fear, distress, and/or pain when they receive oral morphine vs. placebo before a needle is inserted in a subcutaneously implanted intravenous port when combined with topical anesthesia. ⋯ We could not reject the null hypothesis that there is no difference between the oral morphine and placebo groups assuming an effect size of 15 mm on VAS. Therefore it seems that oral morphine at 0.25 mg/kg does not give any additional reduction of fear, distress or pain compared with placebo when combined with topical anesthesia in pediatric patients undergoing subcutaneous port needle insertion, and would not be expected to be of any advantage for similar procedures such as venipuncture and venous cannulation when topical anesthesia is used.

Pain is thought to interfere with training-induced plasticity of corticomotor pathways. Although this implies direct interference with plastic processes, it may be explained by compromised performance in the training task during pain. Repeated finger movements can induce plasticity and change the amplitude/direction of acceleration of finger movement evoked by transcranial magnetic stimulation (TMS). ⋯ There was no change in FDI MEPs in any conditions. These data do not support direct effects of nociceptive input (pain) on training-induced plasticity of corticomotor pathways. Remote pain may compromise learning due to distraction from the training task or other complex central pain processes.

Herpes zoster results from the reactivation of the varicella-zoster virus, which is often accompanied by a prodrome of dermatomal pain. Little is known about the burden of prodromal pain. ⋯ The burden of prodromal pain is significant and should be considered when evaluating the overall benefit of herpes zoster vaccination.

Temporomandibular disorders (TMD) can be related to self-reported musculoskeletal pains. The aim of the study was to investigate the association of clinical findings of TMD with self-reported pain in other parts of the body, and to discriminate pain clusters according to definite profiles of pain conditions including TMD among subjects in general population. ⋯ TMD findings associate with pain in several locations. Female gender and presence of impaired health were particularly related to occurrence of multiple pain conditions.
