Randomized Controlled Trial
A large conditioned pain modulation response is not related to a large blood pressure response: A study in healthy men.
Endogenous pain modulation has been studied with the conditioned pain modulation (CPM) paradigm with large differences in the magnitude of the CPM effect. We hypothesized that differences in CPM effects might be associated with differences in blood pressure responses to the conditioning stimulus when comparing the CPM effects using two different conditioning stimuli. ⋯ Cold pressor pain CS induces larger CPM effects than ischaemic pain CS. The larger CPM effect is, however, not associated with a larger blood pressure response. Other factors related to the CS should be investigated to understand why different CS modalities give different CPM effects.

This study evaluated the prescribing trends of four commonly prescribed strong opioids in primary care and explored utilization in non-cancer and cancer users. ⋯ There has been a huge increase in strong opioid prescribing in the United Kingdom, with the majority of prescriptions for non-cancer pain. Morphine was the most frequently prescribed, but the utilization of oxycodone, buprenorphine and fentanyl increased markedly over time.

Human experimental pain models play an important role in studying neuropathic pain mechanisms. The objective of the present study was to test the reproducibility of the topical menthol model over a 1-week period. ⋯ For an observation period of 1 week, the signs of cold and mechanical hyperalgesia were reproducible with a highly significant correlation of about r = 0.8 and good agreement except for the area size of mechanical pin-prick hyperalgesia. These results demonstrate that the topical menthol pain model is suitable for pharmacological interventions repeated within an observation period of 1 week.

Migraine is an important source of social burden and work-related costs. Studies addressing the association of migraine with job stress are rare. ⋯ We observed a strong association between high-strain jobs and migraine. Job control was a stronger migraine-related factor for women. Low social support was associated with migraine in both sexes.

There are no nationwide trend surveys of the prevalence of musculoskeletal symptoms among university students. The aim of the study was to examine whether the prevalence of perceived musculoskeletal pain symptoms among Finnish university students has changed from 2000 to 2012, and to explore the co-occurrence of these symptoms. ⋯ An increasing trend in the prevalence of frequent musculoskeletal pain was found over the period of 12-years among Finnish university students.
