To identify predictive factors requiring high-dose transdermal fentanyl in opioid switching from oral morphine or oxycodone to transdermal fentanyl in patients with cancer pain. ⋯ Our study indicates that breast cancer, total protein, alanine aminotransferase, advanced age, and male sex are significant predictors of a need for higher dose transdermal fentanyl in opioid switching. Our results are considered likely to contribute to the establishment of evidence-based medicine in pain relief and palliative care.

Assessing pain in elderly persons, who have diminished capacity to communicate verbally, requires use of observational scales that focus upon nonverbal behavior. Facial expression has been recognized as providing the most specific and sensitive nonverbal cues for pain. This study examined the validity of facial expression components of 6 widely used pain assessment scales developed for elders with dementia. Descriptions of the facial expression of pain vary widely on these scales. ⋯ Facial expression items on observational scales for assessing pain in the elderly benefit from adherence to empirically derived descriptions. Those using the scales should receive specific direction concerning cues to be assessed. Observational scales that provide descriptors that correspond to how people actually display facial expressions of pain perform better at differentiating intensities of pain.

Temporomandibular disorders (TMDs) are considered to be comorbid with headaches. Earlier population studies have suggested that TMD may also be a risk factor for migraine progression. If that is true, TMD should be associated with specific headache syndromes (eg, migraine and chronic migraine), but not with headaches overall. Accordingly, our aim was to explore the relationship between TMD subtypes and severity with primary headaches in a controlled clinical study. ⋯ TMD, TMD subtypes, and TMD severity are independently associated with specific headache syndromes and with headache frequency. This differential association suggests that the presence of central facilitation of nociceptive inputs may be of importance, as positive association was observed only when muscular TMD pain was involved.

Randomized Controlled Trial
Efficacy of small doses of ketamine with morphine to decrease procedural pain responses during open wound care.
The purpose of this study was to evaluate differences in pain intensity, pain quality, physiological measures, and adverse effects when patients received morphine with saline (MS) compared with morphine and a small dose of ketamine (MK) before an open wound care procedure (WCP). ⋯ Ketamine with morphine significantly reduced procedural wound pain intensity during WCP. Adverse effects and higher diastolic BP occurred with MK. Further research is warranted to determine the optimal analgesic dose of ketamine or if the addition of a benzodiazepine would mitigate the psychotomimetic effects of ketamine.

The objective of this systematic review was to assess the effectiveness of guided imagery (GI) as a treatment option for musculoskeletal pain (MSP). ⋯ It is concluded that there are too few rigorous RCTs testing the effectiveness of GI in the management of MSP. Therefore, the evidence that GI alleviates MSP is encouraging but inconclusive.
