Randomized Controlled Trial
Pain coping but not readiness to change is associated with pretreatment pain-related functioning.
The purpose of the present study was to determine if readiness to use adaptive and avoid maladaptive pain-coping skills before initiation of psychosocial treatment for chronic pain was related to reports of present coping, and whether those variables, together or separately, explained variance in pain, pain interference, and symptoms of depression. ⋯ Overall, the results indicate that adaptive coping is associated with better pain-related functioning and maladaptive coping is associated with poorer functioning, whereas readiness appears to not play a significant role in patient functioning before psychosocial pain treatment. The findings support the discriminant validity of the coping and readiness measures and inform treatment conceptualization.

Comparative Study
Comparison of a novel direct measure of rapid pain intensity change to traditional serial 100 mm VAS measurement of pain intensity.
Key diagnostic decisions often turn on measurement of change in pain intensity after diagnostic anesthetic blocks. This study aimed to introduce a new direct measure pain intensity change and compare it with percent change as calculated from the traditional preprocedure and postprocedure pain visual analog scales. ⋯ The 2 methods are not interchangeable. The new method measures the pain intensity change dimension directly, whereas the traditional method estimates change indirectly by calculation. Face validity is better served by adopting the new method for decisions regarding whether a patient is a "responder" or "nonresponder" to diagnostic blocks. The traditional method should be retained for estimation of pain intensity preprocedure and the duration of pain relief postprocedure.

To assess pain burden in neonates during their hospitalization in China and thus provide evidence for the necessity of neonatal pain management. ⋯ Neonates, particularly preterm neonates, were exposed to numerous invasive painful procedures without appropriate analgesia in hospitals in China. The potential long-term impacts of poorly treated pain in neonates call for a change in pediatric practice in China and in countries with similar practices.

To identify predictive factors for the occurrence of postherpetic neuralgia (PHN). ⋯ Our study indicates that advanced age and deep pain at the initial visit are significant predictors for PHN. Our results are considered likely to contribute to the establishment of evidence-based medicine in the optimal treatment of PHN.

The objective of the study was to assess diffuse noxious inhibitory control (DNIC) function in women with provoked vestibulodynia (PVD) compared with healthy controls through the use of 2 different methodologies. Furthermore, the study aimed to assess whether pain characteristics correlate with DNIC in women with PVD. ⋯ Results support previous findings of intact DNIC function in women with PVD, using both an ascending method of limits and a temporal summation paradigm. Pain-related variables were not correlated with DNIC function in women with PVD, perhaps this unexpected finding is due to the possibility that central processes other than DNIC, such as descending facilitation, provoke or maintain this chronic pain condition.
