Most pain in patients aged ≥50 years affects multiple sites and yet the predominant mode of presentation is single-site syndromes. The aim of this study was to investigate if pain sites form clusters in this population and if any such clusters are associated with health factors other than pain. ⋯ These results indicate that in a general population aged ≥50 years, pain forms four clusters shaped by two dimensions-number of pain sites (low, medium, high) and, within the medium cluster, the absence or presence of back pain. The usefulness of primary care treatment approaches based on this simple classification should be investigated.

Pressure Pain Sensitivity in Patients With Suspected Opioid-Induced Hyperalgesia.
This study was designed to test whether a brief quantitative sensory testing assessment could be used to detect hyperalgesia in patients with suspected opioid-induced hyperalgesia (OIH). ⋯ Whereas there were no differences between patients suspected of having OIH and the healthy controls, the finding that higher doses of opioids were associated with more sensitivity suggests that dose might be an important factor in the development of hyperalgesia. In addition, male patients demonstrated a hyperalgesic response after a bolus of fentanyl. Future studies are needed to develop better diagnostics for detecting hyperalgesia in the clinical setting.

The detailed course of recovery following compensable whiplash associated disorders (WAD) is not well understood. Some people recover within months and others report symptoms for extended periods. Recent research identified distinct recovery pathways. Identifying recovery pathways for people with this condition in compensable settings could assist clinical and claim management. ⋯ There is a strong and plausible association between severe disability, clinical levels of pain catastrophising and low mental health. Claimants can be identified at claim notification based on three estimated recovery trajectories. Claim and clinical interventions can be targeted to the profile within each recovery trajectory.
