To determine the relationship between chronic pain patients' responses to self-report measures of pain intensity, and self-reported strategies when completing such measures. ⋯ (1) Chronic pain patients' elicited beliefs and strategies concerning how they complete pain intensity questionnaires are sometimes, but not invariably, reflected in their responses to these measures. Thus, purely qualitative methodologies alone cannot provide completely reliable information and point to the need to use a "mixed methods" approach combining both qualitative and quantitative data; (2) the lack of association between pain intensity measures and interference with activities of daily living, as well as relative insensitivity to different etiologies underlines the problem in relying on pain intensity measures as the primary means of evaluating the success of a treatment, either for pain management or in clinical research.

FMRI of spinal and supra-spinal correlates of temporal pain summation in fibromyalgia patients.
Fibromyalgia syndrome (FM) is a debilitating chronic pain condition, which afflicts primarily females. Although the etiology of this illness is not completely understood, FM pain is thought to rely on enhanced pain sensitivity maintained by central mechanisms. One of these mechanisms is central pain amplification, which is characterized by altered temporal summation of second pain (TSSP). ⋯ FM subjects, however, required significantly lower stimulus intensities than NC to achieve similar TSSP. fMRI analyses of perceptually equal TSSP identified similar brain activity in NC and FM subjects; however, multiple areas in the brainstem (rostral ventromedial medulla and periaqueductal grey region) and spinal cord (dorsal horn) exhibited greater activity in NC subjects. Finally, increased after-sensations and enhanced dorsal horn activity was demonstrated in FM patients. In conclusion, the spinal and brainstem BOLD responses to TSSP are different between NC and FM patients, which may indicate alterations to descending pain control mechanisms suggesting contributions of these mechanisms to central sensitization and pain of FM patients.

Pain Management Algorithms for Implementing Best Practices in Nursing Homes: Results of a Randomized Controlled Trial.
To enhance pain practices in nursing homes (NHs) using pain assessment and management algorithms and intense diffusion strategies. ⋯ Future research needs to identify and test effective implementation methods for changing complex clinical practices in NHs, including those to reduce pain.

Randomized Controlled Trial Comparative StudyLidocaine 10% spray to the cervix reduces pain during intrauterine device insertion: a double-blind randomised controlled trial.
Fear of pain during intrauterine device (IUD) insertion can be a barrier to widespread use of this safe and highly effective contraceptive method. Our objective was to determine the effectiveness of topical 10% lidocaine spray for pain control during IUD insertion. ⋯ Significant pain reduction during IUD insertion can be achieved by using 10% lidocaine spray alone. Lidocaine spray can be accepted as a non-invasive, easy to apply and more comfortable local anaesthetic method for IUD insertion.

Randomized Controlled TrialDouble-dorsal versus single-volar digital subcutaneous anaesthetic injection for finger injuries in the emergency department: A randomised controlled trial.
The objective of this present study is to compare pain associated with the double-dorsal versus a single-volar subcutaneous injection in the provision of digital anaesthesia for finger injuries presenting to the ED. ⋯ In ED patients with finger injuries requiring digital anaesthesia, both the double-dorsal or single-volar subcutaneous injection techniques have similar pain of injection and success rates of anaesthesia. Single-volar injection appears suitable alternative to the commonly performed double-dorsal injection in the ED.
