Randomized Controlled Trial
Modification of experimental, lower limb ischemic pain with transcutaneous electrical nerve stimulation.
Transcutaneous electrical nerve stimulation (TENS) has been shown to be effective for the reduction of experimentally induced ischemic pain in the upper limb. No studies have been published on the effects of TENS for lower limb ischemic pain. ⋯ HF-TENS had stronger modifying effects on several aspects of laboratory-induced ischemic pain than did P-TENS. HF-TENS delayed the onset of pain, reduced pain levels, and delayed the onset of extreme pain over a period of several minutes.

Review Case Reports
Use of buprenorphine in children with chronic pseudoobstruction syndrome: case series and review of literature.
Abdominal pain is the most challenging symptom in chronic intestinal pseudoobstruction (CIPO) syndrome, because of its severity and the limited availability of suitable opioid formulations, especially in pediatric patients with digestive problems. Most of the children with CIPO cannot tolerate oral formulations. ⋯ CIPO and the unique pharmacological profile of buprenorphine are reviewed briefly.

Randomized Controlled Trial
The pain quality response profile of pregabalin in the treatment of neuropathic pain.
To identify and describe the response profile of pregabalin on the qualities of pain associated with peripheral neuropathy. ⋯ Pregabalin had a greater effect on PQAS-assessed paroxysmal pain than on surface or deep pain in patients with peripheral neuropathy. The findings corroborate previous research demonstrating differential effects of analgesic drugs across pain qualities, further emphasizing the need to assess individual pain qualities in addition to overall pain intensity.

Previous research suggests that children with autism spectrum disorders (ASD) are at a higher risk for painful experiences, but there is limited research examining pain in children with ASD. ⋯ This is the first study to successfully obtain self-report of pain from youth with ASD. Implications for the understanding of pain and pain assessment in high-functioning youth with ASD are discussed.

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.
