Randomized Controlled Trial
Effect of hypnosis on pain and blink reflexes in patients with painful temporomandibular disorders.
This study contrasted the effect of hypnosis on self-reported pain and changes in a nociceptive brainstem reflex, the blink reflex (BR), in 39 women with temporomandibular disorder. ⋯ Hypnosis thus seems to reduce complex temporomandibular disorder pain, most likely because of cortical changes with little, if any, involvement of brainstem reflex pathways.

We report a case of a 59-year-old female with severe TN who experienced satisfactory symptom relief from a single-shot trial of intrathecal ziconotide. ⋯ Ziconotide should be considered for treatment of TN, although further investigation is recommended.

Measuring outcomes across multiple domains is essential for an adequate understanding of chronic pain and the effects of pain treatment. Pain interference reflects the negative effects of pain on functioning, and is recognized as a critical outcome domain. The Pain Disability Assessment Scale (PDAS) contains items that assess the negative effects of pain on broad spectrum pain interference domains. The purpose of this study was to examine the factor structure, reliability, and validity of the PDAS. ⋯ The PDAS may be useful when researchers or clinicians require a multidimensional measure of the effects of pain on a patient's life.

The main objective of this study was to investigate different psychometric properties of the Swedish version of the Depression, Anxiety, and Positive Outlook Scale (DAPOS) in patients with chronic musculoskeletal pain in an orthopedic setting. ⋯ To be able to rely on an instrument with as few items as DAPOS, the cross-validation of its constructs for sex and diagnostic groups is a valuable information, particularly when investigated in patients with musculoskeletal pain. Based on these results, we recommend that DAPOS could replace longer and more time-consuming screening tests in clinical settings.

Randomized Controlled Trial Comparative Study
Fluoroscopic stellate ganglion block for postmastectomy pain: a comparison of the classic anterior approach and the oblique approach.
Stellate ganglion block is usually performed with the classic anterior paratracheal approach. The anatomy of the stellate ganglion being in close proximity to various critical structures renders a number of complications, which are potentially associated with its blockade. The aim of this study was to assess the analgesic efficacy and safety of a new approach of the stellate ganglion block using an oblique fluoroscopic view. ⋯ The oblique fluoroscopic approach of the stellate ganglion block is as effective as the anterior paratracheal approach but is safer and more satisfactory to the patients.
